Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a urination connector that is connected to a conduit for guiding drainage of an artificial bladder, a urine collection device, or the like.

[Conventional technology]

People with artificial bladders attach an artificial bladder bag to their stoma to manage urine, but sometimes it is necessary to increase the urine storage capacity depending on living conditions, so the artificial bladder bag is connected to a spare leg bag fixed to the leg. At night, the artificial bladder bag is connected to a drainage bag, tank, bottle, etc. using a connecting tube.

In such cases, the urinary opening of the artificial bladder bag and the connecting tube must be connected or separated. Therefore, the first method conventionally used is to insert a rubber tube or PVC pipe of the connecting tube into the urinary opening, but since the inner diameter of the tube is smaller than the outer diameter of the urinary opening, it is difficult to insert and it is difficult to remove. Sometimes, when the tube is pulled, the tube material stretches and acts to tighten the urinary opening, so with rubber tubes it is necessary to remove the tube end by flipping it up with your fingertips, and with PVC tubes, it is necessary to remove it by cutting the tip. As a result, your hands get dirty with urine, and the tube wears out a lot. In the second method, a screw-type connector is used to screw the connecting tube into the urination port, but if urine particles accumulate on the threaded part, it may not move smoothly or may not be completely tightened. Further, each time the screw is tightened, the connecting tube twists, and since the tube is directional, the bag connected to the lower end of the tube may sometimes be oriented in a direction that is difficult to use.

A similar problem occurs when a urine collection device and a urine storage bag are connected.

[Problem that the invention attempts to solve]

The purpose of this invention is to allow devices that are fixed to the patient's body, such as artificial bladder bags, urine collectors, etc., and urine collection bags for excrement to be connected with tubes, so that they can be easily attached and detached without getting the hands dirty. There is no connector available.

[Means for solving problems]

According to the present invention, the above object is to fix the lower ends of a plurality of engaging arms extending in the upper axial direction on the side of a cylindrical connector body and having upper ends curved inward,
The upper end of each engagement arm is provided with an inwardly directed claw that engages with a connecting portion connected to the connector body, and a ring that is movable in the axial direction on the connector body is provided between the connector body and the engagement arm. , the gap between the connector body and the engagement arm is formed to increase or decrease in the axial direction in a section where the ring can move, and the inner diameter of the engagement arm is such that the inner diameter of the engagement arm increases or decreases in the direction in which the gap decreases in that section. The ring has a portion smaller than the outer diameter, and by moving the ring in the direction of decreasing the gap, the upper end of the engaging arm opens outward, and by moving the ring in the direction of increasing the gap, the upper end of the engaging arm closes inward. It's becoming like that.

[Effect]

In the present invention, with the ring moved to a position where the upper end of the engaging arm closes inward, the connector body is pushed into the connection part of the outlet of the artificial bladder bag, urine collection device, etc. to be connected. The engaging arm moves in the axial direction while being pushed outward by the outer surface of the connecting part, and engages and locks with an engaging part, such as a flange, formed on the connecting part, and the connecting part and the connector body are connected. be done. When separating the connector body from the connection part, by moving the ring in a direction that reduces the gap between the connector body and the engagement arm, a force is exerted by the outer edge of the ring to push the engagement arm outward, so that the engagement arm The upper end opens outward, and the claw of the engaging arm disengages from the engaging portion, such as the flange, of the connecting portion, and the connecting portion and the connector body are separated.

〔Example〕

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

1, 2, and 3 are a vertical front view, a side view, and a plan view, respectively, of an embodiment of the present invention, in which a cylindrical connector body 1 is connected to a connection port 2 on the side of an artificial bladder bag, etc. Tube side connection port 3
The lower ends of two engaging arms 4, 5 are fixed at opposing positions on one diameter of the connector body on the outer wall of the connector body 1, which has a extends upward in the axial direction of the connector body, and its upper end curves inward in a dogleg shape, and the gap between the inner wall of the engaging arm and the opposing outer wall of the connector body becomes smaller toward the lower end of the engaging arm. ing.
Claws 6, 7 are provided at the upper ends of the engaging arms 4, 5.

A ring 8 is inserted onto the connector body 1 so as to be located between the connector body 1 and the engaging arms 4 and 5 on the connection port 2 side of the connector body 1,
The ring 8 is adapted to be able to move axially within a gap 9 between the connector body 1 and the engaging arms 4, 5. The outer surface 10 of the ring 8 is slightly inclined inward, and the links 8 form an inverted truncated cone.

The connector body 1 and the ring 8 can be molded from materials such as polyacetal, polypropylene, vinyl chloride, polyethylene, and the like.

Next, a method for attaching and detaching the connector of the present invention will be explained using FIGS. 4 and 5.

In the figure, reference numeral 11 denotes, for example, a connecting portion of an artificial bladder bag, and a flange 13 is provided on the outer wall near the urinary opening 12. Now, when the urination port 12 is inserted into the connection port 2 of the connector body 1, the engaging arms 4,
The claws 6 and 7 at the upper end of the connector 5 follow the outer surface of the connecting part 11, eventually go over the flange 13, and are engaged with the upper surface of the flange 13 to be locked, and the inner wall of the connecting port 2 of the connector body 1 and the artificial bladder bag. The outer wall of the urinary opening 12 is fitted and sealed. Therefore, via the connecting tube connected to the connecting port 3 of the connector body 1, the artificial bladder bag is connected to a drainage bag or the like connected to the tip of the connecting tube.

If you want to remove the connecting tube from the artificial bladder bag now, hold the connector body 1 in your hand and push down the ring 8 in the direction of the arrow, as shown in FIG. Then, the outer surface 10 of the ring 8 pushes the inner surfaces 14, 15 of the engagement arms 4, 5 downward, so the engagement arms 4, 5 move slightly in the direction of opening outward as shown by the arrows.
The claws 6, 7 are removed from the flange 13, the lock is released, and the connection part 11 of the artificial bladder bag can be pulled out from the connector body 1.

Although the above example describes a structure in which the lock is released by pushing down the ring, it is also possible to adopt a structure in which the engagement arm opens outward by pushing the ring up. Further, the number of engaging arms is not limited to two, and three or more engaging arms may be provided at axially symmetrical positions.

FIGS. 6a and 6b are plan and front views of different embodiments of the ring. The ring 16 has handles 17 and 18 on both left and right sides, and the handles 17 and 18 make it easy to separate the rings. can.

[Effect of idea]

According to this invention, it is possible to seal and lock the connector by simply pushing the connector body into the mating side, and the lock is released by simply moving the ring, so it is extremely easy to attach and detach without getting your hands dirty.
It can be used safely even by the elderly and visually impaired, and has the advantage of being compact in structure and without directionality.
