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 anastomosis device, but the one that is currently widely used consists of a skin part that is attached around the patient's stoma and a pouch part that stores excrement; The body side is adhesive 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 on the skin contact part and the bag body. When excreting, 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 after defecation, the bag is removed from the skin. The bag is reused after cleaning. This type of anastomosis 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 the invention] The purpose of the invention is to solve all the problems of such conventional anastomosis devices.

[Structure of the idea]

According to the present invention, this purpose is to include a skin contact part and a bag part, one of the skin contact part and the bag part is a male ring body, and the other is capable of fitting with this male ring body. each having a female ring body attached to the face plate of the skin-contacting part, the open end of the male ring body or the female ring body on the side fitting with the bag part being inclined with respect to the axis of the face plate, This is achieved by tapering the height from the face plate of the male ring body or the female ring body to the open end.

Materials for the male ring body and female ring body include polyethylene, ethylene vinyl acetate, vinyl chloride,
Nylon, polypropylene, preferably polyethylene, ethylene vinyl acetate are suitable.

[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 male ring body and the female ring body in a combined state. In each figure, the same parts are given the same reference numerals.

The skin contact part 1 is a male ring body arranged on a face plate 5 made of a laminate of a release paper 2, a flexible skin protection agent 3, and a polyethylene film 4 so as to surround an opening 6 provided in the center thereof. 7. The open end 8 of the male ring body 7 on the side opposite to the face plate 5, that is, the side that fits with the female ring body, is inclined with respect to the axis 9 of the face plate 5, and the height from the face plate 5 to the open end 8 is one side. (height
h ₁ ) toward the other (height h ₂ ). The male ring body 7 is also provided with a sealing member 10, such as an O-ring, and a groove 11 along the outer periphery near the open end 8, and the inner surface 12 is formed to open slightly conically from the face plate side toward the open end side. has been done.

The bag part 13 has a bag body 14 and a female ring body 15, and the female ring body 15 has an inner ring 1 so as to surround the male ring body 7 of the skin contact part 1 from inside and outside.
6 and an outer ring 17, and a bag body 14 is fixed to the outer surface of a bridging portion 18 of both rings. The inner ring 16 extends along the inner surface 12 of the male ring body 7, and the outer ring 17 is provided with a protrusion 19 on the inner periphery of its open end and partially with a longitudinal split 20.
(four in the illustrated embodiment). The female ring body 15 has an operating knob 21 and a belt hanging flange 22, as shown in FIG.

When installing this device, first peel off the release paper 2 of the skin contact part 1, and use the adhesive function of the skin protectant 3 to fix the face plate 5 to the patient's body so that the stoma, for example, is located in the opening 6. do. Next, hold the operating knob 21 of the female ring body 15 of the bag portion 13 in your hand, and place about half of the protrusion 19 of the outer ring 17 on the male ring body 7 at the lower height from the face plate (in the figure). Insert the outer ring 17 into the groove 11 from the left side (height h ₂ side), then bend the remaining half of the outer ring 17 to widen its open end, so that the protrusion 19 is inserted into the groove 11 from the higher side (height h 2 side) of the male ring body 7 from the face plate. When the female ring body 15 is placed over the male ring body 7 so as to pass over the sealing member 10 on the right side (height h ₁ in the figure) and released, the female ring body 15 fits onto the male ring body 7. At this time, a "click" sound is emitted, allowing you to know that the mating is complete. It is further advantageous that the above-described mounting operation is performed while holding the male ring body 7 with a hand, in that there is no risk of abdominal pressure being applied to the patient. In the fitted state, as shown in FIG. 4, all the protrusions 19 on the inner peripheral surface of the outer ring of the female ring body 15 are fitted into the grooves 11 of the male ring body 7, so both ring bodies 7, 15 are integrated, and the sealing member 10 is pressed against the inner surface of the outer ring 17 to form a sealing function. In addition, the inner ring 16 of the female ring body 15 is in contact with the inner surface 12 of the male ring body 7, and the excrement from the stoma is transferred to both ring bodies 7, 15.
Prevent it from penetrating into the gaps between them. The belt is then passed through the belt hanging flange 22 and wrapped around the body, and the device is ready for use.

If you want to clean the bag after excretion, or if you want to replace it with a new one, remove the belt and then lift the operating knob 21 slightly diagonally upward to release the female ring body 15. The protrusion 19 of the outer ring 17 partially fits into the groove 1 of the male ring body 7.
1, so if the female ring body 7 is further lifted, the two ring bodies 7 and 15 can be easily disengaged, and the bag part 13 can be removed from the skin contact part 1.

In the above embodiment, a male ring body is provided in the skin contact part and a female ring body is provided in the bag part. It is likewise possible to provide a male ring body. Further, the fitting mechanism between the male ring body and the female ring body is not limited to the above-mentioned example, and various types can be used.

[Effect of idea]

The effects obtained by the present invention are as follows.

(1) When attaching the bag to the skin contact area or removing the bag from the skin contact area, fit the male ring body and female ring body while holding the base of the male ring body with your hand. By combining or separating them, it is possible to avoid applying any abdominal pressure that causes pain to the patient.

(2) Since the fitting part of the male ring body or the female ring body of the skin contact part is inclined with respect to the face plate, when fitting both the ring bodies of the skin contact part and the bag part, Among the forces applied between the two, the force that causes pain to the patient is a force perpendicular to the patient's body, and therefore becomes a component of the above-mentioned force, which can weaken the force applied to the patient's body.

(3) Since the open end of the male ring body is tapered, it can function as a protective cover by surrounding an opening such as a stoma.

(4) Since there are no protrusions in the path leading from the opening of the skin-contacting part to the pouch, material discharged from the patient's opening does not accumulate on the way, making it hygienic.

(5) The diameter of the opening in the skin contact area can be increased.
