A stool characterized by having an internal space of a large size, usually housing the stool collection part, and a columnar outer cylinder that allows the stool collection part to be exposed when the pusher is pressed. It is a collection instrument. Preferably, the outer cylinder is tapered and includes a tip made of an elastic body.

This stool collection device can easily collect stool from the rectum by inserting it into the anus of a person or animal.

That is, the stool collection device of the present invention consists of a pusher part (plunger part) and an outer cylinder that encloses and stores the pusher part, and the pusher part has a tapered tip and a plurality of recesses on the surface near the tip. The pusher is equipped with a recessed portion for collecting stool, and a pressing portion at the rear end of the pusher.

Furthermore, this outer cylinder has an internal space large enough to accommodate the pusher main body, and normally accommodates the pusher stool collection section, and when the pusher is pressed from the rear end, the tip of the pusher is It has an opening at the tip to allow exposure of the stool collection part, and is made of an elastic material near the tip.

The tip of the outer cylinder is tapered and open. The tip of the outer cylinder is made of an elastic material and can open when pushed by a plunger.

There is a narrow space between this outer cylinder and the plunger, which can store or hold the collected stool, and a spring is installed near the base of the rear end to push the plunger and release the stool after the stool collection. As soon as the pressure is removed, the plunger returns to its original position and grasps the collected stool.

The stool collection device according to the present invention includes a synthetic resin outer cylinder with a hollow portion, the outer cylinder opening, that is, the vicinity of the tip, is configured to have elasticity, and the other parts of the synthetic resin outer cylinder are elastic. A rod-shaped pusher is inserted from the end, and the pusher is attached to the inner wall of the outer cylinder with a spring. A pressing portion is provided at the base of the pusher for pushing the pusher so that the pusher is exposed from the opening of the outer cylinder. Further, the other end of the pusher, that is, the tip side, is tapered and has a plurality of recesses on the surface near the tip.
It is for collecting stool. This tip is usually
Alternatively, when it is inserted into the rectum, it is stored in the outer cylinder, but when it is pressed for stool collection after insertion into the rectum, it is exposed from the tip of the outer cylinder, causing surrounding stool to adhere to the stool collection recess. It returns to its outer cylinder at the same time without pressing, and stool collection can be easily performed with a simple operation.

The pusher can usually be manufactured from synthetic resin.

Pusher (plunger) of the stool collection device of the present invention
can be made using synthetic resins such as polyethylene, polypropylene, polystyrene, and polyethylene terephthalate.

These synthetic resins can be molded by injection molding, extrusion molding, blow molding, vacuum forming, etc. to make pushers.

Further, it is preferable to use a thermoplastic elastomer for the portion near the tip of the outer cylinder, and for example, it can be molded using an elastomer such as an olefin elastomer or a styrene elastomer.

[Function] When collecting stool, the stool collection device according to the present invention pushes the plunger with a tapered tip and pushes it out of the outer cylinder, so that the stool accumulated in the rectum is pushed into the recess on the surface near the tip of the plunger. When the pressure is released, the pusher returns to the outer cylinder and the stool can be collected.

[Example] Next, the stool collection device of the present invention will be explained using the following specific example, but the present invention is not limited to the explanation.

FIG. 1 is a sectional view showing the structure of a stool collection device according to the present invention.

1 is a plunger member, 2 is a tip of an elastic outer cylinder, for example, a cylinder made of thermoplastic elastomer or rubber, and 3 is an outer cylinder, and as shown in the figure, 3 is thicker than 2 and has a base. It becomes thicker as it gets closer to . 4 is an elastic spring, for example, a plastic or metal spring, and 5 is a toilet recess provided on the outer surface of the plunger.

2 is an elastic body to relieve pain when inserting the stool collection device. 2 and 3 form the columnar outer cylinder of the plunger 1. The outer cylinder 3 need not have more elasticity than the outer cylinder 2, and may be relatively hard.

Further, in detail, the elastic outer cylinder tip 2 gradually becomes thinner from the wide hollow part of the hollow cylinder shape to the narrow tip part, and the elastic force is greatest at the tip and does not damage the rectal wall even when inserted into the rectum. good.

The plunger 1 has a tapered tip and is housed in a space within the tip portion 2 of the elastic outer cylinder, and when inserted into the rectum, the plunger 1 is inserted further into the tip than the tip. That is, the tip of the elastic outer cylinder tip 2 is closed.
Therefore, the tip is easy to push in and does not damage the rectal wall.

As shown in FIG. 3, when the plunger 1 is pushed after rectal insertion, the tip of the elastic outer cylinder 2 opens, and
Feces adhere to the recess 5 provided on the surface near the tip of the plunger 2 and can be stored therein. When the pressure on the plunger 1 is stopped, the plunger 1 is returned by the spring 4, and the plunger 1 returns into the elastic outer cylinder 2. And feces can be stored in it. By covering it with the protector 6 (shown in FIG. 2), it can be held in the hand without any hygienic problems.

FIG. 2 shows, in cross section, a protector (cap) 6 for covering the stool collection device of the present invention after stool collection. That is, it is placed over the tip of the stool collection device after collecting stool to protect the stool and prevent external contamination. Therefore, as shown in the figure, 6 is a hollow cylindrical container that matches the shape of the tip of the stool collection device.
