DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for injecting into a body cavity, which is used for, for example, an enema test in which barium or the like is enema.

[0002]

2. Description of the Related Art This enema test is similar to gastroscopy,
By injecting the barium solution from the anus and changing the body position, the barium solution is moved to the transverse colon as much as possible, and then air is introduced.In this way, the barium solution is converted into the large intestine by repositioning and repeating air supply. To the innermost cecum, and at the same time inflate the large intestine by reinflation, so-called double (with barium solution and air)
This test is performed to diagnose the entire large intestine (from the rectum to the cecum) such as colorectal cancer, intestinal tuberculosis, and inflammatory diseases by imaging.

[0003] As a tool used for such an enema examination, an enema examination tool has been conventionally used. This tool is also called an “enema syringe”, and FIG. 4 is an external view showing one example thereof. As shown in FIG. 4, this tool has a rubber balloon portion B interposed between injection tubes P1 and P2. A valve (not shown) is provided at one end on the side of the injection pipe P1 at an inlet port K for sucking a drug solution or the like. This valve has the function of a check valve that allows only inflow from outside to the injection tube. On the other hand, a discharge port T for discharging a chemical solution or the like is provided at the other end on the side of the injection pipe P2. V is a discharge valve installed near the discharge port T.

Accordingly, when the suction port K at one end of the injection pipe P1 is immersed in the drug solution and the balloon portion B is reduced by hand, the valve (not shown) of the suction port K is closed. As it is, the air in the balloon portion is discharged from the discharge valve V to the discharge port portion T.
Is discharged from Next, when the hand is released, the balloon portion B is restored by the elasticity of the rubber. At this time, the valve at the suction port K is opened to suck the drug solution (barium). Reduction of this balloon part B,
When the pumping operation of the inflation is repeated two or three times, the liquid medicine is sequentially filled in the device. Insert the injection tube P2 side into the anus of the human body. When the pump operation of the balloon portion B is further repeated in this state, the medicinal solution is enema by opening and closing both valves.

[0005]

The conventional inspection tool has a problem in use. That is, cleaning is necessary when using this inspection tool again. The reason is that this test tool is
The two sides are inserted into the patient's anus (rectum) by about 5 to 10 cm, so that feces and the like may enter the infusion tube P2. Therefore, there is a possibility of infection such as AIDS infection, hepatitis (A, B, C) bacterial infection, sexually transmitted disease and the like. Therefore, sufficient cleaning and disinfection are essential. Here, in the case of cleaning, it is necessary to use rubber gloves and carry out with sufficient care. However, this operation requires skill, and cleaning by a layman can sometimes result in infection. In relation to handling filthy materials, hygiene,
Cleaning and disinfection require time and trouble to prevent infection. In particular, it is unclear to what position feces and the like have entered the injection tube P2, and the injection tube is thin and requires careful cleaning and disinfection. Further, if the washing and disinfection are repeated frequently, the portion of the injection tube P2 is worn and damaged, and the discharge port T may be detached from the injection tube P2 in the intestine, which may cause an accident. It can be connected.

Further, the balloon portion B is made of a rubber material. Although the reduction is easily performed by gripping force or the like, the expansion becomes very slow (slow). In particular, when a viscous chemical such as barium is injected, the expansion (restoration) is slow, and there is a drawback that smooth injection cannot be performed.

[0007]

In order to solve the above-mentioned problems, a device for injecting into a body cavity provided by the present invention has a transparent tube detachably provided from a balloon portion to an injection tube on a discharge port side. Therefore, it is possible to visually confirm the state of injection of the infused drug solution and the like by using the transparent tube, and also to know the state of invasion of feces and the like and to which part the invasion has occurred. Further, by disposing the transparent tube in a disposable form, the number of members to be cleaned is reduced.

[0008] Further, the intracavity injection tool provided by the present invention has a balloon portion provided with an elastic portion for expansion.
Therefore, expansion can be performed quickly.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a device for injecting into a body cavity provided by the present invention will be described with reference to embodiments shown in the drawings.

FIG. 1 is a view showing the appearance of a device for injecting into a body cavity provided by the present invention, wherein 1 is a balloon portion, 2 is a suction side injection tube, and 3 is a discharge side injection tube. A suction port 4 is provided at the tip (one side) of the suction-side injection pipe 2. A valve with a check valve is provided in the suction port 6 so as to allow only the inflow of the drug solution from the suction port 4. The balloon portion 1 is made of rubber and has elasticity. The balloon portion 1 is reduced by being pressed by hand, and is expanded and restored by elasticity when released. The chemical solution (barium or the like) is sucked from the suction port portion 4 by the repetitive operation of reducing and expanding (pump operation), and is pumped and discharged on the discharge side injection pipe 3 side.

In the present invention, the transparent tube 5 is detachably connected to the other end of the discharge-side injection tube 3, which is a feature of the present invention. The transparent tube 5 is made of, for example, a vinyl chloride material. In this case, the transparent tube 5 is bendable and can be easily inserted into a body cavity, that is, into the rectum. A discharge port 6 is provided at the tip. This discharge port 6
Also, a check valve type valve (not shown) is provided therein. Then, the inhaled chemical is discharged by the above-described pump operation into the discharge port 6.
From the intestine.

The transparent tube 5 is detachably connected to the discharge-side injection tube 3, and reference numeral 7 is a connecting member. The connecting member 7 has a multi-step uneven portion formed by connecting a plurality of umbrella-shaped protrusions, and has a configuration that allows the transparent tube 5 to be attached and detached and prevents the transparent tube 5 from being inadvertently removed at the time of connection.

In the illustrated example, the transparent tube 5 is a discharge side injection tube 3.
And a discharge port 6. As a way of this interposition, there is no discharge side injection pipe 3 other than the illustrated example, and the entire area between the balloon part 1 and the discharge port part 6 can be made a transparent pipe. Conversely, a discharge side injection pipe 3 connected to the balloon section 1 is provided, and an opaque injection pipe attached to the discharge port section 6 is provided with a slight length, and a transparent pipe 5 is interposed between the opaque injection pipes. You may make it.

In the present invention, the transparent tube 5 is made of vinyl chloride, can be manufactured at low cost, and can be constituted as a disposable member. In this case, the discharge port portion 4 is also small and can be manufactured at low cost, and can be a disposable member like the transparent tube 5. The length of the transparent tube 5 is set so that the injection of the drug solution such as barium reaches the inside of the intestine, and is set in consideration of the longest arrival point of reverse invasion of feces and the like.

The infusion tool provided by the present invention is as described above. At the time of injecting a drug solution, the situation can be confirmed through the transparent tube 5 and the situation of reverse invasion of feces and the like from the body cavity side, The position can be confirmed visually. Further, the transparent tube 5 can be removed from the connecting tool 7 and can be disposable. Therefore,
Cleaning and disinfection work is extremely simplified, and infection can be prevented.

The present invention is further characterized in that the balloon portion 1 is provided with an expansion elastic portion. That is, specifically, as shown in FIGS. 2 and 3, the stainless wire SW is inserted into the convex portion 1 </ b> B of the balloon portion 1. The convex portion 1B is formed so as to protrude about six places around the inner surface, and the stainless wire SW is embedded in the convex portion 1B. FIG. 2 shows a cross section perpendicular to the axis of the balloon portion 1, and FIG. 3 shows a vertical cross section parallel to the coaxial core. Such a stainless steel wire SW functions as an elastic material, and is deformed when the balloon portion 1 is reduced, thereby ensuring that the balloon portion 1 is reduced in size. At the same time, when the balloon portion 1 is expanded, a quick expansion is realized by the elastic force (restoring force) of the stainless wire SW even if the medical solution is filled.

The intracavitary injection device provided by the present invention is as described in detail above, but is not limited to the above and illustrated examples. In particular, the material of the transparent tube 5 is not limited to vinyl chloride alone. The connection device and connection method with the opaque rubber injection tube are not limited to the illustrated example.
However, it is premised that it can be detached and disposable. The injection tool of the present invention can be used as a cleaning tool for the nasal cavity or the like or an enema tool, and can also be used for injection of a drug (a laxative, a hemostatic agent, a medical solution such as a steroid) or a cleaning solution. The elastic portion provided on the balloon portion is not limited only to the inner portion of stainless steel wire or the like. For example, only the rubber material itself of the balloon portion is used to make the inward convex portion (rib portion) large, Also included are those that allow the expansion to be quicker due to the rigidity of the part. Alternatively, a number of stainless wire rings (circular) that deform into a flat ellipse when reduced may be provided on the inner surface in the axial direction of the balloon portion. In this case, rings having different diameters are provided. Thus, the elastic portion is not limited to the illustrated example.

[0018]

As described above, the device for injecting into a body cavity provided by the present invention can be confirmed through a transparent tube when a drug solution such as barium is injected into the intestine. Further, in the case of washing at the time of reuse, the transparent tube can be detached and can be disposable, so that the number of washing members is small and it is simple. In particular, the reverse invasion site of feces and the like can be confirmed, and since the transparent tube is disposable (discarded) on it, there is no risk of infection and the safety is improved. That is, when the reverse penetration of feces or the like extends over the entire length of the transparent tube, thorough cleaning and disinfection including the balloon portion is performed, and safety is improved.

Further, in the intracavity injection tool having an elastic portion provided on the balloon portion, the balloon is quickly expanded, the pump operation is fast, and the injection of a drug such as barium is smoothly performed.
