Abstract

PURPOSE:To obtain an excretion treatment device which gives no damage even though the rectum wall is contacted to the tip of a horn when the excrement is absorbed by operating a process to wash and smash by an ultrasonic wave, and a process to suck and remove the smashed and emulsified excrement out of the living body alternatively in an adequate cycle. CONSTITUTION:By providing a protective cover 13 from the tip of a horn 2 a little longer than the horn 2, a washing liquid is let flow through a circular washing liquid passage 27, and sprayed from the opening 28 at the top of the protective cover 13 to the excrement, in the process when the horn 2 is ultrasonic-vibrated, and the excrement is smashed and emulsified. The washing liquid is atmized and accelerated, its permeability to the excrement is increased, its injection to the inner wall of the rectum which is the organization of a fibrous substance is made softer, and the rectum inner wall is never contacted directly to the horn 2 which is being ultrasonic-vibrated. In the sucking operation, the rectum inner wall is never contacted directly to the tip of the horn 2 when the smashed and emulsified excrement is sucked by a suction hole 21, because the protective cover 13 is longer than the horn 2, and even though an excessive suction pressure is applied, no damage is given to the rectum inner wall, because the ultrasonic vibration of the horn 2 is already stopped.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used for patients with defecation disorders, etc., to efficiently and safely crush feces in the rectum using ultrasonic mechanical vibrations, and remove the feces by suction outside the body. The present invention relates to an excretion treatment device.

[Conventional technology]

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. These methods have been carried out using agents or a combination thereof, 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 for the patient.

(2) A simple method is to put on gloves for internal examination and insert your finger directly into the patient's anus to scrape out the stool, but if the stool is hard, it is difficult to insert the finger into the rectum, making this method extremely difficult. In addition, there is a risk of damaging the rectal mucosa. Moreover, it causes embarrassment to the patient, and is also unpleasant for the operator due to its odor.

(3) The method using suppositories is effective for mild constipation, but has little effect on patients with hard stools.

As mentioned above, conventional methods of defecation treatment do not have a sufficient effect on defecation, and they cause physical and mental pain, especially for patients with dysphagia whose feces are hard, and some methods may damage the rectal mucosa and cause bleeding. There is also the risk of infection, and on the other hand, it is also an aversive task for the defecation practitioner, who has to listen to the defecation work for a long time and has to endure the smell of feces.

As a means to solve these problems in defecation processing, the present inventors have invented a device that efficiently crushes and suctions feces in the rectum using mechanical vibration using ultrasonic waves, and has developed a device that Application No. 62-325506 and Actual Application No. 63-64
Although disclosed in No. 020, the method for preventing damage to the rectal wall was insufficient.

[Problem to be solved by the invention]

The present invention aims to improve the effectiveness of conventional devices that crush and suction remove feces using mechanical vibrations using ultrasonic waves for patients with hard feces, such as patients with defecation disorders, which do not sufficiently prevent damage to the rectal wall. As a result of intensive research to improve the safety of products,
Having obtained the knowledge that damage to the rectal wall caused by ultrasonic vibration can be prevented by alternately operating the washing and ultrasonic crushing process and the suction removal process of crushed and emulsified feces, This has led to the completion of the present invention.

[Means to solve the problem]

The present invention solves the problems of conventional methods,
Its main components are: an insertion tool that is inserted into the rectum through the anus and whose tip vibrates ultrasonically; an ultrasonic oscillator that causes the horn at the tip of the insertion tool to vibrate ultrasonically; In an excretion treatment device comprising a cleaning liquid supply section for softening feces and performing an enema treatment, and a suction section for suctioning and removing feces crushed by ultrasonic vibration from the body, the steps of cleaning and ultrasonic crushing are performed. By alternately operating the steps of , suctioning and removing crushed emulsified feces out of the body in an appropriate cycle, no damage will be caused even if the rectal wall comes into contact with the tip of the horn during suction. This excretion treatment device has the following characteristics.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. 1st
The figure is an overall configuration diagram for implementing the present invention, which mainly consists of an ultrasonic generation section, an irrigation section, and a suction section.
FIG. 2 shows an insertion tool to be inserted into the anus.

First, the ultrasonic ordering section will be explained. The insertion tool (1) has a built-in vibrator such as an electrostrictive vibrator or a magnetostrictive vibrator, and the horn (1) is the tip of the insertion tool (1).
2) produces Rtia-like vibrations of ultrasonic waves. The oscillator (4) is an ultrasonic oscillator for supplying high frequency power in the ultrasonic range to the vibrator (3) via the cable (5).

Next, the irrigation section will be explained. The irrigation pump (6) is a cleaning liquid container (7) that stores a cleaning liquid such as an enema liquid that is isotonic or harmless to living organisms such as physiological saline.
It is a liquid pump such as a roller type that sends the washing liquid into the rectum through the insertion tool (1), and the preheater (8) keeps the washing liquid sent into the rectum at a temperature close to the rectal temperature. , for example, is a warmer with a built-in heater or the like for preheating to about 35 to 42°C. This preheater (8) may be installed at any position between the insertion tool (1) and the cleaning liquid container (7), but it is better to install it between the cleaning liquid container (7) and the irrigation pump (6). However, the irrigation pump (
This is desirable because it eliminates the need to receive the pumping pressure in 6). In addition, the irrigation pump (6) can be omitted if the cleaning liquid container (7) is set at a required height, for example, 50 to 100 cm higher than the insertion tool (1), since the flow will flow due to the head difference. 9) is a tube made of soft vinyl chloride resin, silicone resin, etc., and supplies cleaning liquid to the tip of the horn (2).

Next, the suction section will be explained. The storage container 00) is a suction tube made of soft vinyl chloride resin, silicone resin, etc., which collects excrement such as feces crushed by the ultrasonic mechanical vibration of the horn (2) at the tip of the insertion tool (1). 01), and the insertion tool (
This is a container that is installed between 1) and the Sucsidine pump Oz, and can contain a plastic container, glass bottle, or disposable plastic bag.

A zero force is provided in a penetrating state on the back cover 0ω of the insertion device, and the suction tube 0υ shown in FIG. 1 is connected to this suction nipple surface.

A suction hole (21) is passed through the horn (2) and the vibrator (3) in the axial direction, and connected to the suction nipple (0''7) using an appropriate method such as a rubber tube. [OEL includes a vibrator (
A cable (5) for supplying high-frequency power to 3) is provided in a penetrating state through the back cover θω of the insertion tool, and this cable (5)
is connected to the oscillator (4) shown in FIG. The protective cover 03) is for preventing the ultrasonic vibrating horn (2) from coming into contact with the anus or rectal wall. The rear surface of this protective cover 03) from the irrigation nipple 04),
In other words, there is an 0-ring Of! inside the vibrator (3) side. J is installed to prevent the cleaning liquid from flowing into the vibrator (3) from the annular cleaning liquid passage formed between the horn (2) and the protective cover 0. Inside the insertion tool body 05), the front side of the fixed plate [phase] of the built-in vibrator (3), that is, the horn (
Flight 21 is provided with a vibrator holding O-ring 09) for holding the vibrator (3).

When the vibrator (3) is an electrostrictive vibrator, PZT (
Lead zirconate titanate) is preferred, and its structure is preferably a so-called bolted Langevin transducer (BLT).

Next, the mechanism of action of crushing and suctioning out feces in the rectum according to the present invention will be explained based on FIGS. 1, 2, and 3. Straight part (
22) to an appropriate length straight from the anus (23) into the rectum 1M (24), and inject a cleaning solution such as physiological saline into the rectum through the irrigation nipple 04, and at the same time insert the oscillator (
By supplying the high frequency power generated from 4) to the vibrator (3), the tip of the horn (2) that is in contact with the feces (25) shown in Figure 3 (a) generates ultrasonic waves in the axial direction. It vibrates and begins to crush the feces (25). The cleaning solution removes feces (2
5) is emulsified with the phenomenon of hand-vitesicon. This emulsified feces is pumped through the suction hole in the horn (2) by the negative pressure generated by the suction pump 021.
21), the suction nipple 07), and the suction tube 00, the liquid is suctioned and discharged and stored in the storage container 001. As the feces (25) in the rectum (24) are sequentially crushed and suctioned out, the rectum gradually contracts.
As a result, feces are sequentially supplied to the tip of the horn (2), and all the feces (25) in the rectum (24) can be crushed and removed by suction.

However, if suction is continued with ultrasonic vibration, the inner wall of the rectum (26) will be damaged by the horn (2), as shown in Figure 3(b).
) There is a risk of an accident in which the inner wall of the rectum (26) is damaged by the tip of the horn (2) which is attracted to the tip of the horn (2) and vibrates ultrasonically. As a means to solve this problem, by alternately repeating the process of ultrasonic vibration while performing irrigation and the process of suction, the tip of the horn (2) is protected from the horn (2) while it is undergoing ultrasonic vibration. Washing liquid is ejected from the annular passage formed between the cover side and the ejecting pressure that prevents the inner wall of the rectum (26) from coming into contact with the tip of the horn (2), and during this period, no suction operation is performed. Therefore, the rectal inner wall (26) is not sucked into the ultrasonic vibrating horn (2), and the fecal matter that has been crushed and emulsified by this process can be used in the next step, which is suction only or suction and irrigation. When used in combination, the suction is removed from the body, but if the suction operation is performed while spraying an appropriate amount of irrigation fluid, the emulsified feces in the rectum (24) will be better fluidized and the treatment can be performed without difficulty.

A system for switching between the first step and the second step will be explained based on FIG. 1. The irrigation pump (6), suction pump 02) and oscillator (4) are each electrically connected to a time limit setting device (30).

The time limit setting device (30) consists of a motor timer IC counter, etc., and during the first process of irrigation and ultrasonic crushing, the irrigation pump (6) and the oscillator (4) are in the ON state, and the suction pump 021 is in the ON state. O
In the FF state, during the second step of suction operation, the sakushi town pump 02) is in the ON state, and the oscillator (4) is OFF.
At this time, the irrigation pump Q''IJ can be set to ON or OFF depending on the case.

In addition, instead of turning on and off this succinct pump 021, although not shown, an electromagnetic on-off valve may be installed on the piping of the succinct tube θO to replace this function. This time limit setting device (30) may be provided with a function of repeating each step of step 2 a plurality of times.

FIG. 4 shows an example of a more desirable protective cover shape as an embodiment of the present invention, in which crushing by ultrasonic vibration and suction operation are performed alternately.
By providing a protective cover 03) longer than the tip of the horn (2), the structure prevents the tip of the horn (2), which generates mechanical ultrasonic vibrations, from directly touching the inner wall of the rectum. In the process in which the horn (2) vibrates ultrasonically, the cleaning liquid flows through the annular cleaning liquid passageway (27) formed between the outer periphery of the horn (2) and the inner periphery of the protective cover, and the cleaning liquid flows through the opening at the tip of the protective cover. It is ejected from the horn (28) toward the feces, and the feces are crushed and emulsified by ultrasonic vibrations at the tip of the horn (2). During this process, the jet of cleaning liquid is accelerated by the frequency of vibration in the axial direction of the horn (2), making the cleaning liquid atomized, which increases the permeability to feces and makes it easier to clean the fibrous tissue. The jet is softer against the rectal inner wall, and during the zero-order suction operation in which the rectal inner wall does not come into contact with the ultrasonic vibrating horn (2), the feces crushed and emulsified in the previous step are removed. When suctioning through the suction hole (21),
Since the protective cover θ is longer than the horn (2), the inner wall of the rectum does not come into direct contact with the tip of the horn (2), and even if excessive suction pressure is applied, the horn (2) will not absorb ultrasonic vibrations. Because it is stationary, it does not cause damage to the inner wall of the rectum.

As shown in FIG. 4, the shape of this protective cover tip opening (28) has an R shape, and a tapered protective cover taper part (29) is designed to facilitate insertion during anal insertion. ) is preferable, and the distance between the end face of the protective cover hot water and the end face of the horn (2) is as follows:
0.5 to 1Qam, preferably 1 to 5III in order to prevent the cleaning liquid from being directly sucked into the suction hole (21).
It is better to set it to 11.

The preferable frequency of the ultrasonic waves generated by the oscillator (4) used in the present invention is determined in order to allow the straight part (22) of the protective cover 031 to be inserted into the rectum through the anus to be long, and to make the horn (2) For the purpose of increasing the vibration amplitude, the frequency is 17 to 40 KHz, preferably 18 to 23 KHz.
is appropriate, and the power required to drive the vibrator (3) is 100W to IKW, preferably 200 to 500KW.
W is good, the vibration amplitude of the horn (2) is 40 to 300 μm
, preferably 100 to 200 μm, allows for good fecal fragmentation.

The first step is to crush and emulsify feces using ultrasonic vibration while performing irrigation, and the second step is to perform a suction operation.
A desirable distribution of time for performing these steps alternately is 3 to 20 seconds for the first step and 1 to 10 seconds for the second step, and more preferably 5 to 10 seconds for the first step and 1 to 10 seconds for the second step. 3 to 7 seconds is appropriate.

In addition, between the first step and the second step, as necessary,
And/or a short rest period may be provided between the second step and the next first step. Furthermore, it is also effective to repeat the first step and the second step multiple times with a short rest period in between, for uniformly crushing and emulsifying the feces and ensuring reliable suction removal.

〔Effect of the invention〕

As described above, according to the configuration of the present invention, feces in the rectum can be crushed, emulsified, and removed by suction more efficiently than conventional methods of excretion using enemas, simple methods, suppositories, etc., and there is no fear of damage to the inner wall of the rectum. It is possible to excrete and remove even extremely hard feces in an extremely safe manner, generates little odor, and does not cause physical or mental pain to patients or caregivers. It is possible to provide an excretion treatment device that is medically excellent.
