[Detailed description of the device]

[0001]

[Industrial field of use] The present invention is an insertion tool for an excretion treatment device that is inserted into the rectum of a patient with difficulty in defecation, etc., and efficiently smashes and sucks feces through the vibrating force of ultrasonic waves to remove them outside the body. Regarding

[0002]

2. Description of the Related Art As artificial aging progresses, the number of bedridden elderly people is increasing. Despite the fact that the treatment of excrement is a major problem in daily life for these people, only a urine collection device has been developed as a device for excretion, and diapers are still generally used. is the current situation. However, wearing a diaper not only causes mental pain to the patient but also burdens the nurse.

Further, in the excretion of feces, a method of accelerating defecation such as laxative, enema and anal stimulation is usually adopted depending on the constipation of the patient, and especially for patients with dysphagia, a high-pressure enema. , Stools, suppositories, etc. are used alone or in combination. However, even when these treatments are carried out, the physical and mental distress of the patient and the defecation operator are extremely great.

In order to solve the above-mentioned problems, the present inventors have previously developed and already proposed an excretion treatment device for efficiently crushing and removing stool in the rectum by utilizing mechanical vibration by ultrasonic waves. (JP-A-1-198540 and JP-A-2-1724
71, JP-A-2-218362). Regarding the insertion tool of the excretion treatment device, the ultrasonic horn, etc., Japanese Patent Application No.
-280169 and Japanese Utility Model Application No. 1-52979.

In these prior arts, the basic construction of an insertion tool that is inserted into the rectum and crushes / sucks feces comprises a protective cover 2 and a vibrator 3 at the tip of which a horn 1 is set as shown in FIG. It has a built-in wide-diameter portion at the rear, and a supply hole 5 is provided at the center for penetrating the intestinal washing liquid into the intestine from the horn tip through the inside of the horn 1 from the irrigation nipple 4, and the protective cover 2 A suction nipple 6 for sucking and removing the crushed feces is installed in a taper portion between the large diameter portion and the large diameter portion. In use, as shown in FIG. 4, the insertion tool is inserted into the anus 7, and the intestinal fluid is injected through the small hole formed at the tip of the horn 1 and ultrasonic waves are oscillated to solidify in the rectum 8. 9 is crushed into mud and suctioned to the outside to remove it.

[0006]

However, in the structure of the above-described insertion tool, the power of the oscillating ultrasonic wave propagates only from the tip end in the straight traveling direction (the direction of the arrow in FIG. 4), so that the ultrasonic power does not propagate. There is a problem in that a stagnant part 10 of the feces that is not crushed is formed around the anus located on the side surface of the, and smooth and complete excretion cannot be performed. The purpose of the present invention is to
An object of the present invention is to provide an inserter for an excretion processing device, which has an improved protective cover and has a structure in which ultrasonic power evenly extends to feces located around the anus.

[0007]

The insertion tool of the excretion processing device according to the present invention for achieving the above object is an insertion tool of the excretion processing device for crushing and sucking away feces in the rectum by ultrasonic vibration. The structural feature is a structure in which one or more side holes are formed in a side surface portion located 5 to 100 mm rearward from the tip of the protective cover enclosing the horn.

[0008]

According to the structure of the insertion tool of the present invention, not only the tip of the protective cover but also one or more side holes are formed in the side surface of a specific range. It acts to evenly disperse from the tip hole and side hole of the insertion tool to crush the intervening feces.

The dispersion of the oscillating power effectively increases the target range of the feces to be crushed, and the stool around the anus, which has been stagnant in the conventional insertion tool, is also crushed and sucked smoothly. Therefore, it is possible to always perform a complete fecal excretion process.

【Example】

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 and 2. In these figures, the same components as those in FIGS. 1 and 2 are designated by the same reference numerals.

FIG. 1 is a partially cutaway side sectional view showing an insertion tool of an excrement disposal apparatus according to the present invention, in which 1 is a horn, 2 is a protective cover, 3 is a vibrator, 4 is an irrigation nipple, 5
Is a supply hole, and 6 is a suction nipple. This basic structure is the same as that of the conventional insertion tool shown in FIG. 1, but an improved main body structure such as Japanese Patent Application No. 1-280169 may be used.

The original function of the protective cover 2 is to avoid the situation where the ultrasonically vibrating horn 1 directly contacts the anus or rectal wall, but in addition to that, the crushed feces together with the intestinal fluid are washed. It also serves as a passage for sucking and discharging from the suction nipple 6 to an external storage container, and also functions as a guide tube for ejecting the intestinal cleansing liquid from the supply hole 5 through a small hole at the tip of the horn. Therefore, the tip end of the protective cover 2 is formed with a tip hole 11 of a size large enough to eject the intestinal cleansing fluid. The protective cover 2 is made of metal, plastic,
Although it can be made of an appropriate material such as rubber, it is desirable that it be made of plastic, rubber, or a combination of these materials, which does not give a cold feeling when sliding in the anus.

The structure of the present invention is characterized by a structure in which one or a plurality of side holes 12 are formed in a side surface portion located 5 to 100 mm behind the tip of the protective cover 2. The size of the side hole 12 to be perforated is not particularly limited, and may be any size as long as the rectal wall is sucked and does not come into contact with the horn 1 in the suction stage. The shape of the side hole 11 can be appropriately set to a circle, a rectangle, an ellipse, or the like.
Position the side hole 12 from the tip of the protective cover 2 to 5 to 100 mm
The position of the protective cover to be inserted in the rectum is about 100 mm, and the ultrasonic wave propagating from the tip has a sufficient effect within the range of 5 mm from the tip. Is. Therefore, it is only necessary to form an appropriate number of holes on the same peripheral surface or the stepped peripheral surface in the side surface portion within this range.

FIG. 2 is a sectional view schematically showing a state in which the insertion tool of the excretion treatment device according to the present invention is inserted into the anus 7 and the rectum 8 of a patient for treatment. In this case, the ultrasonic power generated by the oscillation of the horn 1 not only proceeds straight from the tip, but also propagates from the side hole 12 in the peripheral direction. Therefore, the ultrasonic waves are evenly dispersed in the feces staying around the anus, which was conventionally difficult to crush, and the crushing proceeds smoothly.

As a specific example, an insertion tool was prepared using a protective cover made of polysulfone resin in which three oval side holes were bored on the same circumferential surface 10 mm behind the tip, and a contrast agent was orally administered to this. Ultrasound was oscillated while monitoring the X-ray stool that had been inserted into the anus of a piglet and was made radiopaque. As a result, convection, which seems to be a straight flow, was observed from the side hole, and it was confirmed that the convection was acting on the feces staying around the anus.

[0016]

As described above, when the inserter of the excrement disposal device according to the present invention is used, the ultrasonic wave in the peripheral direction oscillated from the side hole of the protective cover propagates not only in the straight direction but also in the peripheral part. Since the stool crushing in the direction proceeds smoothly, it is possible to crush and remove the stool of all parts existing in the rectum surely. Therefore, the fecal excretion treatment progresses rapidly, and the practical effect on the medical treatment is brought about by shortening the treatment time.
