Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spray container for removing deposits accumulated in the nozzle portion of the air/water inlet of a fiberscope.

(Prior technology) When observing or treating the inside of the stomach with a fiberscope, body fluids such as blood, gastric juice, mucous membranes, etc. may enter and adhere to the nozzles of the air and water ports that open at the end of the insertion tube. After use, it solidifies and the nozzles of the air/water supply ports become clogged, making them unusable.

For this reason, conventionally, after use, the fiberscope is hung and its insertion portion is allowed to hang down, allowing body fluids to naturally flow out from within the nozzle of the air/water supply port.

(Problem that the invention aims to solve) However, with this method, not only does it take a long time to drain the body fluid, but also the body fluid cannot be completely discharged and some of it gets stuck inside the nozzle. It remains and solidifies, interfering with the smooth flow of air and water through the air and water ports.

For this reason, a thin needle-like object is inserted into the nozzle of the air/water supply port to remove the coagulated material. It requires skill to insert the needle and remove the coagulated material, and if the nozzle wall is damaged by the tip of the needle during this process, there are problems such as having to replace the expensive air and water inlets. The point was hot.

It is also possible to insert the nozzle of a spray container filled with compressed gas into the air/water supply port and use the gas flow pressure to expel body fluids adhering to the nozzle of the air/water supply port to the outside. The air and water supply ports are provided at the tip of the tube-shaped light guide extending from the operating section of the fiberscope, while the nozzle is provided at the tip of the tube-shaped insertion section extending from the tip of the operating section. Since the air/water inlet passage in the light guide section is provided with a spray nozzle, the operation section allows you to connect the air/water inlet passage in the light guide section to the air/water inlet passage in the insertion section, and connect the air/water inlet nozzle to the spray nozzle. The operation of inserting and fitting the connector into the connector must be performed at the same time, and this requires two workers, which complicates the operation and prevents smooth operation.

The object of the present invention is to provide a fiberscope spray container that can solve these problems.

(Means for Solving the Problems) In order to achieve the above object, the fiberscope spray container of the present invention is a container filled with compressed gas such as fluorocarbon gas, as shown in the drawings corresponding to the embodiments. Fiberscope a on main body 1

In parallel with the spray nozzle 2, an insertion guide part 5 for the light guide 6 provided in the air/water supply port 7 of the fiber scope a is provided in the vicinity of the spray nozzle of the container main body 1. It is something.

(Function) After or before use of the fiberscope, when the light guide 6 protruding from the tip of the light guide part is inserted into the insertion guide part 5 provided on the main body 1 of the container, the light guide 6 becomes the insertion guide. Spray nozzle 2 is guided by air/water inlet 7 which is guided by part 5 and protrudes from the light guide 6 at a certain distance.
to fit.

Even if you let go of the device in this state, the light guide 6 is supported by the insertion guide portion 5, so the air/water inlet 7 remains fitted into the spray nozzle 2.

Next, the passage in the light guide section of the air/water supply port 7 is brought into communication with the passage of the air/water supply port of the insertion section, which has a nozzle at its tip, and the light guide section is pressed to open the spray nozzle. 2
When the air/water supply port 7 is pressed against the air/water supply port 7, the spray nozzle 2 moves back and the compressed gas in the container passes from the air/water supply port 7 through the passage in the light guide section.
The air is rapidly injected from the inside of the operation part to the outside from the nozzle 11 through the air/water supply port passage in the insertion part, and the body fluid remaining inside the nozzle 11 is instantly blown away.

(Example) To explain the example of the present invention with reference to the drawings, 1

Reference numeral 4 denotes a cylindrical wall body made of a suitable material such as synthetic resin, which is attached to the container main body 1 so as to surround the spray nozzle 2, and whose lower part is fitted onto the container main body 1 and fixed to the main body 1, or is inserted into the main body 1. It is removably covered, and its upper part protrudes from the upper end surface of the container main body 1.

Reference numeral 5 denotes an insertion guide section made of a small diameter tube integrally fixed to the inner circumferential surface of the cylindrical wall body 3, which protrudes from the distal end surface of the light guide section c made of a flexible tube extending from the operating section b of the fiberscope a. The provided light guide 6 is inserted and fitted so as to be vertically slidable.

Moreover, an air/water supply port 7 is provided at the tip of the light guide part c in parallel with the light guide 6,
The opening at the tip of the air/water inlet 7 is fitted into the tip of the spray nozzle 2. Therefore, the center of the spray nozzle 2 and the insertion guide part 5
The center-to-center dimension of is equal to the center-to-center dimension of the light guide 6 and the air/water supply port 7 .

Note that the insertion guide portion 5 need not be formed into a cylindrical shape, but may have any shape such as a ring shape that can guide the light guide 6 in the vertical direction.

Reference numeral 8 denotes a cover part that closes the upper end opening of the cylindrical wall body 3, and has a support hole 9 in the center thereof through which the tip of the spray nozzle 2 is inserted, and a support hole 9 in the vicinity of the support hole 9. A guide light insertion hole 10 is bored through which the upper end opening of the insertion guide portion 5 is exposed.

To clean the inside of the air/water supply port nozzle 11 exposed at the distal end surface of the insertion section d, which is a flexible tube extending from the operating section b of the fiberscope a, using the spray container configured in this way. After or before using fiberscope a,
When the light guide 6 protruding from the tip of the light guide part c is inserted into the insertion guide part 5 provided on the top surface of the container main body 1, the tip of the air/water inlet 7 arranged parallel to the light guide 6 will be inserted into the container. It is inserted into the tip opening of the spray nozzle 2 of the main body 1.

In this state, operate section b of fiberscope a.
After closing the vent hole 12 protruding from the light guide section c with a finger to prevent gas from leaking from the passage communicating with the air/water supply port 7 provided in the light guide part c, , when the light guide 6 is inserted and pushed into the guide part 5, the air/water supply port 7 moves down together to push down the spray nozzle 2, and the container main body 1 is pushed down.
The compressed gas inside blows out into the air/water supply port 7.

This ejected gas passes from the air/water passage provided in the light guide part c, through the passage in the operating part b, through the air/water passage in the insertion section, and reaches the open end of the air/water passage. The nozzle 11 is ejected to the outside, and at that time, the body fluid adhering to the inner surface of the nozzle 11 is blown out and removed.

FIG. 3 shows another embodiment of the present invention, in which the cylindrical wall body 4 is formed to have a small diameter, and its lower end is connected to the inside of the upper mouthpiece 13 of the container body 1 in which the spray nozzle 2 is disposed in the center. It is fitted integrally or removably with the circumferential surface, and the insertion guide portion 5 is integrally provided on the outer circumferential surface of this cylindrical wall body 4.
