Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved defecation treatment device for inserting into the rectum of a patient with dysfecation or the like and smoothly and safely shaving and removing stool.

[0002]

2. Description of the Related Art As the population ages, the number of bedridden elderly people is increasing. In addition, there are many people with physical disabilities due to traffic accidents and congenital factors, and nearly half of them are accompanied by nerve palsy. For these people, although the treatment of defecation is one of the major problems in daily life, only a urine collection device has been developed as a defecation device, and a laxative and an enema still remain for fecal defecation treatment. Alternatively, a method of urging defecation such as excretion is adopted. Particularly, for patients who have a hard stool with difficult symptoms of defecation, a means of forcible excretion is combined with a combination of treatments such as high-pressure enema, defecation, and suppositories, but these treatments are physical to the patient. Not only does this cause severe psychological distress, but also the defecation practitioner has to engage in defecation work for a long time, and is obliged to perform aversive work that must endure the odor of feces.

As a means for solving such various problems in defecation treatment, the present applicant has already developed many excretion treatment devices for efficiently crushing and removing feces in the rectum by utilizing mechanical vibration. However, it has been proposed (JP-A-1-198540).
JP-A-2-218362, JP-A-3-140161, JP-A-3-151981, JP-A-5-345017, JP-A-5-161711, and JP-A-5-309133. ).

Among these, the defecation treatment device according to Japanese Patent Laid-Open No. 345017/1993 inserts an insertion tool equipped with a horn that causes mechanical vibrations into the rectum through the anus, and irrigation means for lavage fluid and suction means for crushed feces. In a device for excrement and removal of feces via, a pressure sensor for detecting the internal pressure on the irrigation side and the suction side,
It is a mechanism including a pressure control unit for actuating / stopping an irrigation pump, a suction pump, and a drive unit of a vibration source in response to a signal from the pressure sensor.

[0005]

According to the defecation treatment device having the above-mentioned pressure control unit (Japanese Patent Laid-Open No. 5-345017), the internal pressure signals on the irrigation side and the suction side captured by the pressure sensor are detected by the pressure control unit. When the overpressure exceeds the preset pressure range, the irrigation pump and vibration drive are automatically stopped, and at the same time, the suction pump is operated to remove the feces by suction, and the internal pressure decreases to the set pressure. When it falls below the level, the suction pump stops, the irrigation pump operates to raise the rectal internal pressure, and the mechanism that drives the vibration source to vibrate the horn repeats the process. Therefore, the rectal internal pressure that fluctuates during the excretion treatment process is automatically adjusted to an appropriate range, and the defecation treatment can be safely and smoothly advanced.

However, in this mechanism, since the suction pump is stopped at the stage when the irrigation pump and the vibration drive section are activated, the feces attracted by the suction means are re-energized by the enema fluid ejected from the insertion tool and the straightening energy of the horn. There has been a problem that the fecal fragmentation effect is incomplete due to the phenomenon of migration from the tip of the insertion tool to the depth of the rectum.

The present invention has been made to solve the above problems, and at least after the operation stage after the start of vibration drive, the suction means is always operated, and the rectal pressure fluctuates in this state. An object of the present invention is to provide a stool processing apparatus capable of crushing and sucking and removing stool safely and efficiently by a mechanism that activates / stops an irrigation means and a vibration drive unit.

[0008]

In order to achieve the above object, the defecation treatment device according to the present invention has an irrigation means for enema fluid by inserting an insertion tool having a horn that causes mechanical vibration into the rectum through the anus. And a device for discharging and removing feces through the suction means of crushed feces, a vibration sensor, a pressure sensor for detecting the internal pressure on the irrigation side and the suction side in a state where the irrigation pump and the suction pump are operated, and the pressure sensor The operation of the irrigation pump or / and the vibration drive unit is stopped when the internal pressure obtained by the signal from reaches the high pressure upper limit set value, and is restarted when the internal pressure drops to the high pressure lower limit set value. Between the control unit that has a control mechanism that operates the drive unit and the insertion tool and the suction pump. Is installed in the suction tube, pressure is characterized in the configuration that a safety valve mechanism for opening operation when it reaches the lower pressure limit set value.

In addition, the defecation treatment method according to the present invention uses the defecation treatment device described above, until the internal pressure reaches the high-pressure upper limit set value or before a predetermined period of time before the vibration drive section starts operating. The internal pressure is always high by operating only the irrigation pump inside the chamber and then repeatedly operating the vibration drive unit, the irrigation pump and the suction pump within a separately set period, or operating only the suction pump. It is characterized by the step of holding between the upper limit set value and the low pressure lower limit set value.

[0010]

According to the apparatus of the present invention, the pressure sensor installed in the system captures the internal pressure state on the irrigation side and the suction side and transmits the signal to the control section. During operation,
The suction pump, which is a suction means, operates at all times except at the initial stage before the start of vibration drive, sucks and removes crushed feces inside the rectum, and sequentially attracts new solid feces to the anus. Run.
When the irrigation amount is superior to the suction amount and exceeds the predetermined high pressure upper limit set value, and the internal pressure of the rectum becomes overpressure, the control unit operates, and the vibration drive unit that automatically becomes the irrigation pump and / or the crushing means is set. Stop it,
Prevents heat generation due to vibration. When the internal pressure of the rectum decreases to a predetermined high-pressure lower limit set value due to the operation of the suction pump, the irrigation pump or / and the vibration drive section are automatically operated. On the other hand, when the suction amount becomes larger than the irrigation amount and the negative pressure degree of the suction pipe reaches a certain low pressure lower limit set value, the safety valve opens and the negative pressure does not fall below the low pressure lower limit set value. Even if the set amount of irrigation amount is not balanced, it is possible to operate within an appropriate pressure range.

Further, according to the stool processing method of the present invention using the above-mentioned device, the stool can be swollen and suspended by water by irrigation for a certain period of time which is operated before starting the crushing means, and thereafter, It is possible to control the internal pressure between the high pressure upper limit set value and the low pressure lower limit set value by repeating the cycle of vibration drive, irrigation, and suction switching.

Due to such an action, the rectal internal pressure fluctuating during the excretion treatment process is automatically adjusted to an appropriate range, and the stool in the rectum is attracted to the vicinity of the crushing means by the constant operation of the suction means to effectively crush and remove it. Therefore, it is possible to perform a complete defecation removal process within a short time.

[0013]

Embodiments of the present invention will be described below in detail with reference to the overall configuration diagram shown in FIG. The insertion tool 1 to be inserted into the anus has a horn 2 which is a vibration source inside,
Typically, the structure shown in FIG. 1 of JP-A-5-309133 is used.

In FIG. 1, the solid line route indicates the piping lines on the irrigation side and the suction side. The piping line on the irrigation side is connected to the irrigation nipple of the insertion tool 1 via the enema solution container 3, the irrigation pump 4, and the irrigation chamber 6 by the irrigation pipe 5. The suction-side piping line includes a storage container 11 from the insertion tool 1 through the suction pipe 7, the pressure measurement port 8 and the suction pump 10.
to go into. The enema fluid container 3 is a tank for storing the enema fluid, but it is also possible to preheat the enema fluid by a not-shown preheater or the like to reduce irritation to the intestine. The enema solution does not need to be sterilized, and tap water can be used.

A safety valve 9 is provided in the suction pipe 7 between the insertion tool 1 and the suction pump 10 so that there is no crushed feces in the rectum, or a phenomenon such as suction of the intestinal wall occurs so that a certain amount of stool remains. When the degree of negative pressure is reached, the opening operates,
Prevents intestinal damage due to excessive suction. The strength of suction is
Control is performed by the rotation speed of the suction pump 10, but if the safety valve 9 is opened, excessive suction does not occur even when the suction pump 10 is rotating at high speed. As the safety valve 9, a check valve having a mechanism in which the valve is closed by the force of the spring until a certain low pressure lower limit setting value is reached, and when the low pressure lower limit lower limit setting value is reached, the spring force is overcome to open the valve. Is preferred.

In FIG. 1, the route shown by the broken line is the sensing line, and the route shown by the alternate long and short dash line is the control signal line. The irrigation chamber 6 and the pressure measurement port 8 are connected to the pressure sensor 13, and the signal captured by the pressure sensor 13 is transmitted to the control unit 14.
The control unit 14 normally stops the operation of the irrigation 4 and / or the vibration drive unit 12 by the signal of the pressure sensor 13 when the irrigation amount exceeds the suction amount, and the suction pump 10 that constantly operates reduces the pressure to a predetermined pressure. At this point, the control mechanism is designed to operate the irrigation pump 4 and / or the vibration drive unit 12 again.

When ultrasonic waves are used as the crushing means of the insertion tool 1, irrigation is necessary also for the purpose of suppressing heat generation of the horn 2 due to the vibration thereof. Therefore, the control unit 14 simultaneously operates the irrigation pump 4 and the driving unit 12. The mechanism is such that The pressure sensor 13 is -760 to 7
It suffices if it can measure within the range of 60 mmHg, and the type may be a gauge type or a differential pressure type, but it is preferable to use a differential pressure type that can measure both positive and negative pressure with reference to atmospheric pressure. It is suitable.

The material of the irrigation pipe 5, the suction pipe 7, the sensing line (pipe) shown by the broken line, which constitutes the piping line, is preferably made of soft polyvinyl chloride or silicone resin. The irrigation chamber 6 and the pressure measurement port 8 are not particularly limited in type of material as long as they are transparent resins whose contents can be observed.

In the defecation process, the tip portion of the insertion tool 1 is inserted from the anus into the rectum. The enema fluid is supplied to the irrigation tube 5 by the irrigation pump 4 and injected into the rectum from the tip of the insertion tool 1 through the irrigation chamber 6. The suction pump 10 is actuated, and at the same time, the vibration drive unit 12 is actuated to apply the crushing vibration to the insertion tool 1. The pressure sensor 13 detects the internal pressure of the rectum as a signal from the irrigation chamber 6 or the pressure measurement port 8 while the vibration drive unit 12, the irrigation pump 4, and the suction pump 10 are operating.
When the detected pressure exceeds a predetermined high-pressure upper limit set value, the irrigation pump 4 and / or the vibration drive unit 12 is stopped by the control signal from the control unit 14, and the internal pressure due to the suction of the suction pump 10 that is constantly operating. Wait for the drop. When the internal pressure of the rectum decreases and reaches the high-pressure lower limit setting value, the signal of the control unit 14 restarts the operation of the irrigation pump 4 and / or the vibration drive unit 12. Further, when the suction is strong and the degree of negative suction pressure reaches a constant low pressure lower limit set value, the safety valve 9 automatically opens to return the pressure to the normal lower limit value.

In the above-mentioned defecation treatment operation, before the operation of the vibration drive unit 12 is started, the internal pressure reaches the high-pressure upper limit set value in order to swell and float the feces, or within a predetermined fixed period. A state in which an operation for operating only the irrigation pump 4 is inserted, and then the vibration drive unit 12, the irrigation pump 4 and the suction pump 10 are operated within a separately set fixed period,
Alternatively, it is a preferable processing method to keep only the suction pump 10 in an operating state and repeat the operation of always maintaining the internal pressure within the range between the high pressure upper limit set value and the low pressure lower limit set value. Therefore, after the operation of the vibration drive unit 12, the suction pump 10 is always operated to attract feces in the rectum to the anus side, and when the vibration drive unit 12 is operated, the irrigation pump 4 is always operated to prevent heat generation. Ready to go.

This fecal treatment method can be operated as follows. First, before the vibration drive unit 12 starts operating, only the irrigation pump 4 is operated for a predetermined period, and then the operation period of the vibration drive unit 12 is fixed and the irrigation pump 4 and the suction pump 10 are simultaneously operated. Then, during the operation period of only the irrigation pump 4, when the internal pressure reaches the high-pressure upper limit set value, the operation is switched to the operation of only the suction pump 10 and at the same time the operation period of the vibration driving unit 12 is started. During operation, vibration drive (including operation of irrigation pump and suction pump) and operation switching of only suction pump keeps internal pressure between high and low high limit settings even when irrigation is stronger than suction. To do. Therefore, for the operation, for example, after performing the irrigation step for 5 seconds,
The timer is set to cycle the vibration drive and suction at the same time for 15 seconds, and the operation is continued while repeating each operation. Further, when the suction becomes stronger than the irrigation and the internal pressure reaches the low pressure lower limit installation value, the safety valve 9 automatically operates to prevent the pressure from becoming lower than this value.

FIG. 2 is a graph schematically showing changes in intestinal pressure when such an operation is repeatedly performed under the condition that irrigation is stronger than suction. That is, when the irrigation is stronger than the suction and the intestinal internal pressure rises, the irrigation and the vibration drive are temporarily stopped at the time (a) when the high pressure upper limit setting value is reached. When the intestinal pressure decreases due to the effect of suction and decreases to the high-pressure lower limit set value (b), irrigation and vibration drive are restarted. When the high voltage upper limit setting value is reached in the middle of the irrigation when combining the irrigation steps (c), adjustment is performed by shifting to the operations of irrigation / vibration drive / suction even within the set time of the irrigation step. With such an internal pressure adjusting mechanism, it is controlled within a predetermined pressure range while repeating the vertical movement as shown by the graph line.

FIG. 3 is a graph schematically showing changes in intestinal pressure when the above-described repeated operation is performed under the condition that suction is stronger than irrigation. In this case, the intestinal pressure tends to decrease during irrigation / vibration drive / suction operation, resulting in negative pressure.
When this negative pressure degree reaches the low pressure lower limit set value, the safety valve 9
Is operated so that it does not become an excessive negative pressure (d).
