Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drip counter used for adjusting a drip rate during drip work of medical infusion.

[0002]

2. Description of the Related Art Conventionally, in a natural drip infusion device, a nurse measures the number of infusions per minute while visually observing. There is also a method in which a sensor detects the number of drug drops dropped in the drip cylinder, and the calculated number is calculated by converting the number of drops dropped per unit time.

[0003]

However, the visual adjustment is very inaccurate in addition to the time and effort required to alternately visually count the second hand of the wristwatch and the number of drip. Further, the sensor type requires a large size of the entire apparatus and is expensive and complicated to handle. Therefore, an object of the present invention is to provide a liquid infusion drip counter that can easily grasp the number of natural drip infusions and that is convenient to carry.

[0004]

In order to solve the above-mentioned conventional problems, the drip counter of the present invention comprises means for setting and inputting a designated number of drops of infusion solution per unit time in an infusion device, and unit time of the infusion solution. A means for inputting the actually measured number of drops, a means for comparing and calculating the designated number of drops and the actually measured number of drops, and it is determined whether the actually measured number of drops is within the allowable range of the designated number of drops based on the comparison calculation result. And means for doing so.

Further, the means for inputting the actually measured number of drops of the infusion solution is configured so that the start of the drop measurement is the first drop, the number of drops below is counted, and the desired number of drops can be selected with the input button. Further, the result display means for displaying the determination result as to whether or not it is within the permissible range on either or both of the warning sound and the counter panel display makes it possible to easily adjust the number of drops.

[0006]

[Function] Since it is possible to immediately determine and display whether or not the designated number of drops of the infusion solution and the actually measured number of drops are within the allowable range, the number of drops can be easily adjusted.

Further, since the input of the actually measured number of drops only needs to be made by selecting the input of the first drop to be started and the input of the desired several drops thereafter, it is extremely possible to grasp the actually measured number of drops. It's easy.

[0008]

Embodiments of the present invention will now be described with reference to FIGS. Here, FIG. 1 is a front view showing the appearance of the drip counter, and FIG. 2 is a block diagram showing the configuration of the drip counter.

In FIG. 1, the drip counter is composed of a card-shaped main body 1, and on the board surface thereof, a photocell as a power source 2, a designated drop number input section 3, a measured drop number input section 4, a digital display plate 5, and The comparison result display portion 6 is formed.

Reference numeral 31 is a numeric keypad for inputting a designated number of drops. 41
Is a drop count push button, and the buttons of numbers 1, 4, 6, and 8 are formed to have a slightly different size or shape from the other number buttons. This is for distinguishing the number buttons corresponding to the number of drops to be easily pressed. 5 is a digital display board. Reference numeral 6 is a comparison result display unit, 61 is within the range, 62 is a down arrow, and 63 is an up arrow, which is used for instructing to decrease or increase the number of drops.

Therefore, a method of using the drip counter of the present invention will be described.

The designated drip number determined by the infusion amount of the drip device and the drip time instructed by the doctor is the infusion set constant 19 or 60 (drop / m) at the designated drip number input section.
Press l) to specify, then enter the infusion volume and drip time with the numeric keypad, and press [=] to display the calculation result on the digital display plate 5.

There is a case in which it is known that, for example, this infusion solution is dropped by 56 drops for 1 minute without calculating the specified drop number. In such a case, enter 56 with the numeric keypad, [=]
If is pressed, 56 is entered as the specified number of drops, which has the same effect as the above calculation result.

Next, the nurse adjusts the flow rate regulator of the drip device to measure the number of trial drops of the infusion solution, and starts the work to approach the specified number of drops. For the actual measurement of the number of drops for this purpose, pay attention to the drop situation of the drip cylinder, press the start button of the first drop at the same time as the drop, and then perform 4, 6 or 8 below.
Press the same button as the number of drops on any of the drops. Pressing 8 when the drip is early and pressing 4 or 6 when the drip is slow makes the timing easier. For example, if the sixth drop is pressed after pressing the first drop at the start, the number of seconds taken during that time is divided by 60 seconds and the dropping interval is multiplied by 5, to be converted into the number of drops per minute. It is convenient to display this converted value as the actually measured number of drops on the digital display unit 5 for about two seconds, replacing the specified number of drops.

At the same time, the specified number of drops and the actually measured number of drops are compared and calculated by the calculator 7, and the judging device 8 judges whether the specified value is within the permissible range, above or below the allowable range, and compares. Within the range of the result display portion 6, 61, down arrow 62, up arrow 6
It is displayed in any one of 3.

Looking at this result, the nurse operates the flow regulator of the drip device at the time of the down arrow 62 and conversely operates the flow regulator of the drip device at the time of the up arrow 63 to open it. Then, the adjustment work as described above is repeated again.

The measurement and adjustment are repeated until the permissible range of the designated number of drops of the infusion solution in which the actually measured number of drops is set in this way is reached. Normally, if the difference is within ± 5% with respect to the specified number of drops, it is regarded as within the allowable range.

Although the case of converting the number of drops per minute at the time of designation and actual measurement has been described as an example, the same result can be obtained even if comparison is made at intervals of each drop. Needless to say.

Further, as a display of the comparison result, when the deviation is out of the permissible range, an alarm sound may be given. According to this, there is an advantage that the adjustment can be made more surely because the information can be confirmed by eyes and ears.

[0020]

In summary, according to the apparatus of the present invention, the designated drop number can be easily obtained by operating the designated drop number input section 3 without using a general-purpose calculator or the like. In addition, when counting the number of trial drops, you can easily count by simply pressing each button while counting the number of drops, without using a wristwatch or the like. In addition, the comparison calculation results are displayed as sounds or arrows, making them easy to use and easy to adjust. It is small and lightweight and fits in your pocket, making it easy to carry to each hospital room.
