Description

  The present invention relates to a disposable enema device that is inexpensive, easy to handle, and excellent in sealing performance.

  Conventionally, in medical institutions such as hospitals and clinics, enema is performed on patients before surgery, and surgery is performed after excretion of stool in the rectum or large intestine. In addition, even when a pregnant woman delivers, an enema is given before delivery.

  In the case of applying these enemas, conventionally, an injection enema device containing a 50% aqueous solution of glycerin was used. After injecting into the rectum, the enema device was washed, refilled, and repeatedly used. .

In recent years, however, disposable enemas have come into use as blood infections such as AIDS and hepatitis B have become a problem.
As such an enema, a container is known which has a bellows-like container and is completely infused with a chemical solution to prevent inhalation of stool in the rectum (see, for example, Patent Document 1 and Patent Document 2). .)
Patent Document 1 describes an enema device having a bellows-like container body. In this case, an injection tube is provided at the top of the bellows-like container, an enema liquid agent inlet is provided at the bottom of the container, and an enema liquid is filled from this inlet. For this reason, the opening of the bottom of the container is heat sealed with aluminum foil to seal the enema solution, but an expensive machine is required, or the container cylindrical part is simply inserted into the injection tube with an adhesive. Because of the adhesive structure, there was a risk that the enema solution would leak. Patent Document 2 describes another type of bellows-like enema. In this case, an injection tube with a cap (bending nozzle) is attached to the injection port of the container. However, since only the cap is used, there is a possibility that the enema liquid may leak.

  An object of the present invention is to provide a hygienic and disposable enema device that has a simple structure, does not leak an enema solution, and can quantitatively and inject the enema solution without waste.

  That is, the present invention provides a bellows-like container body that accommodates an enema solution provided with a container mouth tube, an inner stopper, a long infusion tube, and a removable tube cap provided at the tip of the infusion tube. In the enema device, which compresses the bellows and injects the enema solution in the container body into the body cavity from the tip of the injection tube, the container tube portion of the container body has a diameter that can be filled with the enema solution. In addition, a screw thread is provided on the outer periphery outside of the container mouth tube portion, and the inner plug is a fitting tube fitted on the inner periphery of the container mouth tube portion and an insertion tube inserted into the rear end of the injection tube. And a cap at the boundary of the insertion tube and the insertion tube, and the injection tube has an injection hole for the enema liquid at the tip and is screwed onto the outer periphery of the container mouth tube at the rear end It is related with the enema organ characterized by having.

According to the present invention, since an enema solution such as glycerin can be filled from the container mouth tube portion at the top of the container, filling is easy. Further, the inner plug is fixed by the jaw portion being sandwiched between the container mouth tube portion and the rear end of the injection tube, and the inner tube fitting tube is fitted to the inner periphery of the container mouth tube portion, and the insertion tube Is inserted into the rear end of the injection tube, thereby closely contacting the inner periphery near the rear end of the injection tube. As a result, the joint between the container mouth tube and the injection tube is sealed. And, by screwing the cap provided at the rear end of the tube to the main body, the outer periphery of the inner plug is more closely attached to the inner periphery of the container mouth tube portion and the inner periphery of the rear end of the injection tube, so that leakage of the enema liquid does not occur .
In addition, since it is a bellows type container, if the finger is left compressed, the enema solution does not flow back and the enema solution can be injected in a fixed amount.

Hereinafter, the present invention will be described in detail with reference to the drawings.
The enema apparatus of the present invention comprises a bellows-like container body 1, an inner stopper 2, and a long infusion tube 3. The enema apparatus of the present invention injects the liquid agent in the container body 1 into the body cavity from the tip of the injection tube 3 by compressing the bellows 4. Since the container body 1 has a bellows shape, the enema liquid can be easily quantitatively injected.
The container body is formed of a synthetic resin such as polyethylene, polypropylene, or vinyl chloride. The synthetic resin that composes the container body is moderately flexible and rigid so that the bellows of the container body is reversed by compression and the original shape cannot be restored against the reverse pressure from the body cavity even when the compression force is released. It is preferable that the resin has stretchability and elasticity, and low density polyethylene is preferable from these points.

The plurality of bellows elements constituting the bellows-shaped container body have a diameter that gradually decreases toward one of the ends of the container body, and each bellows element intersects the first surface that intersects at the top thereof. The first surface is reversed to the second surface side of the adjacent bellows element by compression of the bellows, and is not restored to the shape before compression by releasing the compression force. It is preferable to do.
When the bellows of the container main body is compressed, the first surface of the bellows element constituting the bellows is reversed to the second surface side of the adjacent bellows element, and is in close contact with or close to the second surface. As a result, the internal volume of the container body is reduced, and the enema solution in the container body is injected into the human body through the injection tube.

  At this time, the reversed first surface does not return to its original state even when the compressive force is released because the elasticity acts in the direction of reversal. In addition, if the bellows element is gradually reduced in diameter as it goes toward one of the ends of the container body, the bellows element having a large diameter covers the bellows element having a small diameter when the bellows element is reversed. The enema solution in the container can be almost completely injected by overlapping all bellows elements.

  The container mouth tube 5 provided in the container body 1 is provided with an opening of a size that can be filled with an enema solution, so that it can be easily filled with an enema solution such as glycerin as in a normal container. Can do. A screw thread 6 is provided on the outer periphery of the container mouth tube portion 5.

  The inner plug 2 includes a fitting cylinder 7 fitted to the inner periphery of the container mouth cylinder 5, an insertion cylinder 8 inserted into the rear end of the injection tube 3, and a boundary portion between the fitting cylinder 7 and the insertion cylinder 8. It consists of the buttocks 9 of. The inner plug is preferably a high-pressure low-density polyethylene from the viewpoint of hermeticity. The fitting cylinder 7 is fitted to the container mouth cylinder part 5 up to the collar part 8.

The injection tube 3 has an enema liquid jetting hole 10 at the front end and a cap 11 screwed onto the outer periphery of the container mouth tube at the rear end. A removable cap 12 is provided at the tip of the injection tube 3. The insertion tube 8 of the inner plug 3 is inserted in close contact with the tube portion of the injection tube 3. The injection tube 3 is preferably made of a soft vinyl chloride resin, and by screwing a cap 11 with a screw provided at the rear end into the container mouth tube portion 5 to the flange portion 9, The fitting cylinder 7, the injection tube 3, and the insertion cylinder 8 are brought into close contact with each other, and leakage from the connection portion between the injection tube 3 and the container mouth tube portion 5 can be prevented.
When the injection tube is made of a soft plastic material and the inner plug is made of a hard plastic material, the insertion tube of the inner plug is pressed against the inner peripheral wall of the injection tube, thereby further preventing leakage.

  Since the enema apparatus of the present invention has a simple structure in which two large parts are simply connected by an inner plug, the number of parts is small and can be manufactured at low cost.

The bellows container body is made of Nippon Polyethylene Co., Ltd. low density polyethylene LB280, the inner plug is made of Sumitomo Chemical Co., Ltd. high pressure method low density polyethylene G201-F, and the injection tube is made of Koyo Kasei Co., Ltd. soft polyvinyl chloride resin FG650. To form an enema.
Ten enemas were filled with enema solution and packed in a cardboard box for transportation, but no leakage occurred during transportation.
