この発明はオートクレーブなどの消毒を有効に
行なうことができるようにした内視鏡に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope that can effectively disinfect an autoclave or the like.
一般に、内視鏡を消毒する手段としては、薬液

う。 By the way, the main body of the endoscope has an airtight structure. Therefore, in order to autoclave or sterilize the endoscope with ethylene oxide gas, when a pressure that varies from near vacuum to about 2 atmospheres is applied to the body of the endoscope, the body sterilizes its interior and exterior. damage due to the pressure difference between the

ら、その都度コツクの開閉操作を行なわなければ
ならないという煩わしさがあり、しかも薬液消毒
を行なう際にコツクを閉じ忘れて本体内に薬液を
流入させてしまう虞れもある。 Therefore, in the past, when the main body was sterilized, the pressure inside and outside of the main body was equalized by drilling a hole in the main body or installing a hole in this hole, thereby preventing damage to the main body. This was what was being done. However, if the main body is simply provided with a through hole, when the main body is immersed in a chemical liquid for disinfection, the chemical liquid will flow into the main body through the through hole, which is an inconvenience. On the other hand, if the hole is equipped with a hole, it is possible to prevent the chemical solution from flowing into the main body by closing the hole, but when performing autoclaving etc., the hole must be opened. There is a hassle of having to open and close the pot each time, and there is also a risk that the pot may be forgotten to close when disinfecting with a chemical solution and the drug solution may flow into the main body.

提供することにある。 This invention was made based on the above circumstances, and its purpose is to provide a through hole in the main body, provide a valve body to seal the through hole, and prevent the valve body from changing external pressure. An object of the present invention is to provide an endoscope in which the main body can be easily and reliably sterilized by automatically opening the through hole in response to the need.

を密封するように付勢されている。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In the figure, 1 is the main body of the endoscope. This main body 1 has a curved portion 2 and a tip forming portion 3 at the tip.
It consists of a flexible tube 5 having an operating section 4 provided at its rear end, and a connector 6 connected to the operating section 4. The operating portion 4 is provided with a through hole 7 that communicates the inside and outside thereof. A substantially cylindrical receiver 8 is attached to the inner surface of the operating portion 4 facing the through hole 7 with screws 9, and a valve body 10 is accommodated within the receiver 8. This valve body 10 is moved to the through hole 7 by a spring 11 as a first valve body release means provided in the receiver 9.

態が設定されている。 Further, a support member 13 is provided upright in the vicinity of the through hole 7 in the operating portion 4, and a bellows 14 that expands and contracts in response to fluctuations in external pressure connects one end of the support member 13 in the axial direction. . A pressing body 15 is attached to the other end of the bellows 14 so as to face the through hole 7, and this pressing body 15 and the bellows 14 constitute a second valve body release means. In addition, main body 1
The mounting state of the bellows 14 is set so that the pressing body 15 does not press the valve body 10 when the pressure is at atmospheric pressure.

つたのち２気圧程度まで上昇する。したがつて、
上記本体１は、その内部と外部とに圧力差が生
じ、この圧力差によつて損傷する虞れがある。 When the endoscope main body 1 having the above configuration is to be autoclaved, for example, the main body 1 is placed in an airtight container (not shown), the inside of this container is preheated, and then high pressure steam is introduced into the container to disinfect the main body 1. However, at this time, the pressure inside the container becomes negative and then rises to about 2 atmospheres. Therefore,
There is a pressure difference between the inside and outside of the main body 1, and there is a risk of damage due to this pressure difference.

て、本体１が損傷することがない。 Therefore, when the external pressure becomes negative pressure, as shown in FIG. and displace this valve body 1.
Since the through hole 7, which had been sealed by 0, is opened, the inside of the main body 1 has the same pressure as the outside, and the main body 1 is not damaged. Further, when the external pressure becomes positive pressure, the bellows 14 contracts as shown in FIG. Displaced against the biasing force of valve body 1
0 is spaced apart from the main body 1 and opens the through hole 7, so the pressure inside the main body 1 is the same as the outside in this case as well, and the main body 1 is not damaged.

薬液を流入させてしまうこともない。 That is, according to the endoscope having the above configuration, the main body 1
The pressure inside the valve is automatically adjusted by the first and second valve release means so that the pressure is the same as the outside pressure.
Disinfection by autoclaving or ethylene oxide gas sterilization can be performed without damaging the main body 1. Furthermore, when the main body 1 is under atmospheric pressure, the valve body 10 seals the through hole 7, so when the main body 1 is immersed in a chemical solution for disinfection, the chemical solution may flow into the main body 1. Nor.

As shown in FIG. 5, if the valve body 10' is formed of an elastic material and one end is fixed to the inner surface of the operating portion 4 so as to close the through hole 7, this valve body 10'' deforms as shown by the chain line in the figure in response to fluctuations in external pressure, causing the valve body 10' to separate from the main body 1 and open the through hole 7. As in the above embodiment, the inside of the main body 1 is exposed to external pressure. can be made the same as

て有用である。 As described above, the present invention provides a main body having an airtight structure with a through hole that communicates with the inside thereof, and seals this through hole from the inside of the main body with a valve body.
Since the main body is provided with a valve release means that acts on the valve body to open the through hole in response to fluctuations in external pressure, the through hole is opened in response to fluctuations in external pressure. Therefore, even if negative or positive pressure is applied to the body in order to, for example, autoclave the body, the inside of the body is automatically maintained at the same pressure as the outside through the through hole, so there is no risk of damaging the body. It is possible to sterilize an autoclave, etc. without exposing it to air. Further, when the main body is disinfected with a chemical solution under approximately atmospheric pressure, since the above-mentioned through hole is closed, the chemical solution does not flow into the main body, which is extremely useful in practice.
