Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a surgical anastomosis device to be attached to a patient after a surgical operation.

[Prior art and its problems]

An anastomosis device attached to the human body is used to collect excrement and fluid from an opening in the human body, such as a stoma, fistula, or wound surface, such as a surgically formed colostomy or artificial bladder. This is well known. There are various types of this anastomotic device, but the one that is currently widely used consists of a skin-contacting part that is attached around the patient's stoma and a pouch part that stores excrement; It is adapted to be adhesive on the human body side and has a convex ring on the side opposite to the human body side, while the bag part has a concave ring that can fit with the convex ring of the skin contact part and the bag body, When in use, the bag is fixed to the skin by fitting the concave ring on the bag into the convex ring on the skin, in a so-called snap-lock style, and the bag is removed from the skin after excretion. After cleaning the bag, it is reused. This type of anastomotic device has the advantages of being easy to operate, being economical as the pouch can be reused, and being able to change the direction of the pouch. When fitting the convex ring on the inner part and the concave ring on the pouch part, a certain amount of external pressure must be applied to securely lock the ring. This causes abdominal pressure, especially when fitted to a patient immediately after surgery, causing extreme pain. In addition, it is not easy to confirm whether or not the mating is complete, so excrement may leak during use when the mating is incomplete, or excessive force may be applied to the patient. It has the disadvantage of causing pain as described above, and furthermore, excrement accumulates on the back side of the fitting part between the convex ring and the concave ring, which cannot be removed even by cleaning, making it unsanitary and potentially becoming a breeding ground for bacteria. be. In addition, the convex ring on the skin contact area is covered with a thin film.
Alternatively, it is attached to the body of the skin contact part through a bellows so that it is flexible, and the external pressure during fitting is supported by the hand from the back side of the convex ring, so that abdominal pressure is not applied to the patient. Although some of the above-mentioned drawbacks have been solved, considerable force is still required to fit the convex and concave rings together, and the effective diameter of the opening is small, making it difficult for the film, There remain drawbacks such as the fact that it is not easy to remove excrement adhering to the bellows, and the operability is not very satisfactory.

[Purpose of invention]

The present invention aims to solve all of the problems of conventional anastomosis devices.

[Structure of the idea]

According to the present invention, this purpose is to provide a skin-contacting part and a bag part, one of which can be fitted into a male ring body, and the other can be fitted into this male ring body. The male ring body or the female ring body provided on the skin-contacting part is arranged so as to be able to surround an opening formed in the human body, and the female ring body provided on the pouch part The mold ring body or the male ring body has a bag body on the side opposite to the skin-contacting part, the male ring body has a groove and a sealing member arranged along its outer periphery, and the female ring body consists of an inner ring and an outer ring that surround a male ring body, the inner ring extends along the inner surface of the male ring body, and the outer ring has a projection provided on the inside that can be inserted into and removed from a groove in the male ring body. This is achieved by becoming like this.

Providing a vertical split in the outer ring of the female ring body makes it easier to fit the male ring body and the female ring body, and is advantageous because no pressure is applied during fitting.

Suitable materials for the male ring body and the female ring body include polyethylene, ethylene vinyl acetate, vinyl chloride, nylon, and polypropylene, preferably polyethylene and ethylene vinyl acetate, from the viewpoint of sealing properties. Further, the sealing member can be formed of a general sealing material such as rubber, silicone rubber, or urethane rubber.

[Example of idea]

Next, embodiments of the present invention will be described with reference to the drawings.

Figures 1 to 4 show a male ring body on the skin contact side.
An embodiment of the present invention is shown in which a female ring body is provided in the bag part, FIG. FIG. 3 is a plan view of the skin portion, FIG. 3 is a plan view of the bag portion, and FIG. 4 is an enlarged sectional view of the main parts in a state where the male ring body and the female ring body are connected. In each figure, the same parts are given the same reference numerals.

The skin-contacting part 1 has a male ring body 6 arranged on a laminate of a release paper 2, a flexible skin protection agent 3, and a polyethylene film 4 so as to surround an opening 5 provided in the center thereof. Along the outer periphery, this male ring body 6 is provided with a groove 7 at its base and a sealing member 8, such as an O-ring, above the groove 7. Male ring body 6
The inner surface 9 is formed so as to be slightly conical and open outward from the skin-contacting side.

The bag part 10 has a bag body 11 and a female ring body 12, and the female ring body 12 is connected to the male ring body 6 of the skin contacting part.
an inner ring 13 so as to surround it from the inside and outside.
and an outer ring 14, with a bridging portion 1 between both rings.
A bag body 11 is fixed to the outer surface of 5. The inner ring 13 extends along the inner surface 9 of the male ring body 6,
The outer ring 14 is provided with a projection 16 on the inner periphery of its open end and is also partially provided with longitudinal splits 17 (four in the illustrated embodiment). In addition, female ring body 1
2 has an operating knob 18 and a belt hanging flange 19, as shown in FIG.

When installing this device, first peel off the release paper 2 of the skin-contacting portion 1, and use the adhesive function of the skin protective agent 3 to fix it to the patient's body so that, for example, a stoma is located in the opening 5. Next, holding the operating knob 18 of the female ring body 12 of the bag portion 10 in your hand, insert about half of the protrusion 16 of the outer ring into the groove 7 at the base of the male ring body 6, and then insert the remaining half of the outer ring. When the open end of the female ring body 12 is expanded by bending it and placed over the male ring body 6 so that the protrusion 16 exceeds the sealing member 8 of the male ring body 6 and the hand is released, the female ring body 12 becomes the male ring body. Fits on body 6. At this time, a "click" sound is emitted, allowing you to know that the mating is complete. In the fitted state, as shown in FIG. 4, all the protrusions 16 on the inner peripheral surface of the outer ring of the female ring body 12 are fitted into the grooves 7 of the male ring body 6, so both ring bodies 6, 12 are integrated, and the sealing member 8 is pressed against the inner surface of the outer ring 14 to form a sealing function. Furthermore, the inner ring 13 of the female ring body 12 contacts the inner surface 9 of the male ring body 6 to prevent excrement from the stoma from entering the gap between the two ring bodies 6 and 12. Next, the belt is passed through the belt hanging flange 19 and wrapped around the body, and the device is ready for use.

When the pouch is to be washed after excretion or when it is to be replaced with a new pouch, the belt is removed, and the operating knob 18 is grasped and lifted in a slightly upward diagonal direction, so that the protrusion 16 of the outer ring 14 of the female ring body 12 partially fits into the groove 7 of the male ring body 6.
Therefore, by further lifting the female ring body 12, the engagement between the two ring bodies 6, 12 can be easily released and the bag portion 10 can be removed from the skin attachment portion 1.

In the above embodiment, the male ring body is provided in the skin contact part and the female ring body is provided in the bag part. It is likewise possible to provide a male ring body. Furthermore, the split provided on the outer ring of the female ring body has the effect of making it easier to warp the outer ring of the female ring body and widen its open end during installation, but this effect is due to the material that makes up the outer ring. It is not necessary to provide it because it is sufficient to obtain the property that it originally has.

[Effect of idea]

According to the present invention, the following various effects can be obtained.

(1) When installing, the female ring body can be partially inserted into the male ring body, and the remaining part of the female ring body can be fitted by simply pushing in lightly. It is not necessary to push the convex ring of the skin-contacting part and the concave ring of the pouch part with great force over the entire circumference of both, and there is no pain to the patient.

(2) The fit between the male ring body and the female ring body is achieved by three elements: the sealing member and groove of the male ring body, and the protrusion of the female ring body. The inner sides of both ring bodies exposed to the holes can be formed with a structure unrelated to the mechanism necessary for fitting, that is, for example, in a tapered shape without protrusions, so that even if excrement adheres to this part, it will not occur. Easy to remove and hygienic.

(4) The wall of the male ring body or female ring body formed on the skin-contacting part can be stood upright, and additional mechanisms such as bellows are not required, so the effective diameter of the opening can be made large. can.
