Description

[Detailed Description of the Invention] The present invention relates to a washer-disinfector for fiberscopes.

A fiberscope consists of an operating section provided with various operating buttons and a tube body provided with an objective lens, an air/water supply port, etc. at the tip, and has a structure in which both are connected by a connecting portion. In addition, a guide cord containing air and water pipes, electric wires, etc. is connected to the operating section.

When this fiberscope is used, mucus from organs and germs adhere to the tube body, so this must be removed in preparation for the next use.
However, the main purpose of the fiberscope tube is
It is difficult to clean due to its 120cm long and narrow shape.
Currently, except in cases where disinfection is essential, such as with biliary fiberscopes, it is simply wiped with alcohol gauze.

Since the fiberscope's tubular body comes into contact with organs, from the standpoint of hygiene, it is desirable to clean and disinfect not only the biliary fiberscope but also all fiberscopes.
Therefore, fiberscope cleaners have recently been developed and provided. However, this cleaning device is extremely large and complicated to handle, and involves various problems in terms of use, installation location, etc. In other words, the large size means that installation locations are limited, and it is not always possible to install it near the location where the fiberscope is used, and it may be necessary to transport it to a distant location for cleaning. . In particular, recent fiberscopes are integrated into a unit, including a light source device that is connected to the operating section via a guide cord.
If the light source device was disconnected each time it was cleaned, the significance of unitization would be lost. Furthermore, the large size makes it impossible to install one cleaning device for one fiberscope, which may reduce cleaning efficiency. Furthermore, the handling is complicated, which means that when a large number of people are being examined continuously, cleaning cannot be done in time for the next person after the end of the examination for one person, and many fiberscopes are required. Must be prepared.

In view of these points, the present applicant has filed Utility Application No. 57-190270 (U.S. Pat.
No. 59-93503) and Utility Model Application No. 58-58890 (Japanese Utility Model Application No. 59-164602) have been filed for cleaning devices for fiberscopes, but both of these cleaning devices are designed for cleaning only the insertion section of fiberscopes. The purpose is cleaning. However, the so-called operation part is not directly inserted into the patient's body and is not directly contaminated, but when the examiner's hands are contaminated, it is a site that is contaminated through the hands. Therefore, it is desirable that the entire fiberscope, including the operating section, be cleaned and disinfected after at least one day of use for medical examinations.

Therefore, the present applicant has proposed a fiberscope washer-disinfector that is small and easy to handle, and is capable of cleaning and disinfecting the entire fiberscope including the operating section. (Jitsugan 58-58890).

However, this method was designed to clean the tubular body with a cleaning liquid. This method is not suitable for cleaning operating parts that have poor watertightness, and there are also problems in using a cleaning liquid for the pipe body.

Therefore, the fiberscope washer/disinfector of the present invention has a tube insertion section formed into a diameter that allows the fiberscope tube to be inserted, one end of which is closed and the other end is open, and a fiberscope that is connected to the open end of the tube insertion section. It consists of a main body storage part in which the operation part of the scope can be stored, and a pipe is provided in the main body storage part, and the injection nozzle provided in the pipe is directed into the main body storage part, and a part of the main body storage part can be opened and closed. It is characterized by

Embodiments of the present invention shown in the drawings will be explained in detail below.

The fiberscope washer/disinfector of the present invention consists of a tube insertion section 1 and a main body storage section 2.

The pipe body insertion part 1 is made of a flexible material such as rubber or synthetic resin that does not change in quality with detergents or disinfectants and does not leak water, and is made of a metal pipe, etc., and has a closed end with one end closed or a removable plug. 11 is provided, and a socket is provided as necessary, and the other end is an open end 12, and is formed to have a diameter that allows the tube body 31 of the fiberscope 3 to be inserted therethrough.

The main body storage section 2 is formed into a shape that can accommodate the operation section 32, connection section 33, etc. of the fiberscope 3, and has a base section 2 connected to the open end 12 of the tube insertion section 1.
1 and a removable lid 22 joined to the base 21, and a substantially cylindrical body whose upper end may be sealed or opened, but a part or all of one side thereof may be closed by force. Some have a joint 24 that can be opened by. A semicircular notch is provided in the base 21 and the lid 22 at the joint portion of the two, and both the notches join together to form the guide cord 3 of the fiberscope 3.
4 through holes 23. It is desirable that the joint structure between the base 21 and the lid 22 be, for example, a structure that allows them to be fixedly held as a fitting structure. In addition to this fitting structure, in the case of a structure in which they simply face each other, a protrusion is provided on one side of the base 21 and the lid 22, and a latch is provided on the other, and the two are fixed and held by this fixture. Good too. Also,
At the joint portion between the two and the inner peripheral surface of the insertion hole 23,
It is desirable to provide packing material. Joint part 24
For example, it is opened and closed using a fastener, but is molded so as to form an overlapping part and then pull it open. In this case, an insertion hole 23 for the guide cord 34 of the fiberscope 3 is formed at the end of the joint 24 .

When using the fiberscope washer/disinfector of the present invention, first remove the lid 22 of the main body storage section 2,
Move the fiberscope 3 from the tip of the tube body 31 to the base 2.
When the fiberscope 3 is further inserted into the tube body insertion part 1 and the operating part 32, connecting part 33, etc. of the fiberscope 3 are stored in the main body storage part 2, the guide cord 34 of the fiberscope 3 is inserted into the base part 21 as the insertion hole 23. It locks into the semicircular notch provided. Therefore, the lid 22 is inserted into the insertion hole 23 in the locked guide cord 34.
The lid 22 is placed over the base 21 so as to match the notches provided in the lid 22.

Furthermore, the base 21 and the lid 22 are fixed using the fixing tool 4 as necessary.

In the case of the joint part 24, the fiberscope 3 is inserted from the tip of the tube body 31 into the tube body insertion part 1 by opening and closing the joint part 24, and the operation part 32 is inserted into the body storage part 2.
The joints 24 such as fasteners or overlapping parts
Close. At this time, the guide cord 34 is also surrounded by the extension of the joint 24. Reference numeral 8 denotes pleats provided in the cylindrical main housing portion 2 as needed, and are formed to facilitate opening and closing of the joint portion 24.

In this way, the fiberscope washer/disinfector of the present invention that houses the fiberscope 3 has a sealed structure. The packing material 5 reinforces this sealed structure.

Reference numeral 4 denotes a pipe, the end of which is connected to a cleaning agent container, a disinfectant container, and a water supply, and is provided with a pot or the like so that desired chemicals and water can be selectively supplied. The tip of the pipe 4 is inserted into the main housing 2,
Alternatively, the upper end is inserted from the open part or positioned above the open part. In addition, a nozzle 41 such as a spout is formed inside the main housing portion 2 of the pipe or above the opening. It is preferable that the nozzle 41 is directed toward the inside of the main body storage section 2. A desired cleaning agent or disinfectant (preferably in the form of a liquid agent) is sent through the pipe 4 and is sprayed inward from the main housing 2 from the nozzles 41, 41. Rinse with water before and after using cleaning solution and disinfectant, and when desired. It is also possible to blow out hot air from a nozzle through the pipe 4 for hot air drying.

The fiberscope washer/disinfector of the present invention can also be disinfected with gas if it has a sealed structure. That is, if a disinfectant such as formalin is added together with the fiberscope 3 when the fiberscope 3 is stored, it is possible to penetrate and disinfect even finer areas than the liquid.

Further, the tube body 31 in the tube body insertion section 1 may be cleaned and disinfected in the conventional manner, but since the cleaning and disinfecting liquid ejected from the pipe 4 is directly flowed into the tube body insertion section 1, it can also be used as is.

When using the fiberscope washer/disinfector of the present invention, as shown in FIG. You can use it by placing it on top or standing it up. Even when used upright, the center of gravity of the current fiberscope 3 is designed so that the guide cord 34 can be hung over the hand.
By supporting the guide cord 34 in the insertion hole 23 provided in the main body storage part 2, the fiberscope 3
maintains a normal posture and does not cause any damage to any parts.

As described above, according to the present invention, the entire fiberscope including the operating section can be cleaned and disinfected, and since the operating section is cleaned and disinfected with a liquid gas injection, there is no infiltration of the liquid, and work can be carried out reliably and with peace of mind. Furthermore, there is provided a washer-disinfector for fiberscopes that is easy to operate without requiring any human labor, and is small and easy to handle.
