Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used for patients with dysuria, etc., to efficiently and safely crush and suction the feces in the rectum using mechanical vibrations of ultrasonic waves, and remove them from the body. Possible excretion treatment! This is related to the J position.

(Prior art) As the population ages, the number of bedridden elderly people is increasing. For these people, disposal of excrement is a major problem in their daily lives, but the only excretion device that has been developed is a urine collection device, and diapers are still commonly used. be. In addition to the mental pain experienced by patients who wear diapers, the physical and mental burden on caregivers associated with changing diapers is also large, and excretion disposal has become an important factor in the problem of bedridden elderly people.

For fecal excretion treatment, methods such as laxatives, enemas, and anal stimulation are usually used to encourage defecation depending on the patient's constipation status. Suppositories or a combination of these have been used, but these methods have the following problems.

(1) With high-pressure enema, if the patient has hard stools, the patient may not be able to defecate completely and it will take a long time, causing great pain to the patient.

(2) The method of dissection is to put on gloves for internal examination, insert a finger directly into the patient's anus, and scrape out the stool; however, if the stool is hard, it may be difficult to insert the finger into the rectum. This is an extremely difficult procedure, and there is a risk of damaging the mucous membrane within the rectum.Furthermore, it causes embarrassment to the patient, and is an unpleasant task due to the odor and the like for the operator.

(3) The method using suppositories is effective for mild constipation, but is hardly effective for patients with hard stools.

As mentioned above, conventional methods of defecation treatment do not provide sufficient defecation efficiency, and cause physical and mental pain, especially for patients with dyschezia whose stools are hard, and some methods may damage the rectal mucosa and cause bleeding. There is also the risk of infection, etc., and on the other hand, it is a very unpleasant task for the person performing the defecation procedure, which requires a long period of time and the necessity of enduring the odor of feces.

[Purpose of the invention]

The present invention aims to eliminate the need for conventional techniques such as enema or disimpaction, which cause physical and mental pain for patients, practitioners, and caregivers over a long period of time for patients with hard stools, such as those with dyschezia. As a result of intensive research to improve what was already there, we discovered that the feces in the rectum can be efficiently (and safely) crushed and suctioned out of the body using mechanical vibrations using ultrasonic waves. The processing device has now been completed.
