Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a defecation treatment device for inserting into the rectum of a patient with dysfecation or the like to smoothly and safely remove stool by crushing and sucking.

[0002]

2. Description of the Related Art As the population ages, the number of bedridden elderly people is increasing. In addition, there are many people with physical disabilities due to traffic accidents and congenital factors, and about half of them are accompanied by nerve palsy. For these people, although the treatment of defecation is one of the major problems in daily life, only a urine collection device has been developed as a defecation device, and a laxative and an enema still remain for fecal defecation treatment. Alternatively, a method of urging defecation such as excretion is adopted. Particularly, for patients who have a hard stool with difficult symptoms of defecation, a means of forcible excretion is combined with a combination of treatments such as high-pressure enema, defecation, and suppositories, but these treatments are physical to the patient. Not only does this cause severe psychological distress, but also the defecation practitioner has to engage in defecation work for a long time, and is obliged to perform aversive work that must endure the odor of feces.

As a means for solving such problems in the defecation treatment, the present inventors have developed an excretion treatment device for efficiently crushing and removing the feces in the rectum by utilizing mechanical vibration. Have already been proposed (JP-A-1-198540, JP-A-2-218362, JP-A-1-280169, JP-A-1-293369, etc.).

In these excrement disposal devices according to the prior art, the control mechanism is mainly performed by the time limit setting device. That is, as shown in FIG. 2, the basic configuration of the conventional device is such that the irrigation side has an irrigation pipe 6 from an irrigation liquid container 3 to a preheater 4 and an irrigation pump 5 in an insert 1 having a horn 2 built in at a distal end thereof. And a suction pipe 7 is connected to the storage container 8 and the suction pump 9 on the suction side, and an oscillator 10 for vibrating the horn 2 is connected to the insertion tool 1. . The time limit setting device 11 is connected to the irrigation pump 5, the suction pump 9 and the oscillator 10, and serves as a mechanism for controlling the processes of intestinal washing, crushing and suction according to the set time.

[0005]

However, in the control method using only the time setting device, the internal pressure of the rectum becomes too high, for example, in the process of washing the intestines or crushing, and conversely, the internal pressure of the rectum becomes low in the step of sucking and removing feces. Since it is impossible to detect and deal with the situation that becomes too much, it is not possible to eliminate the rectal damage or the pain and discomfort of the patient due to such a rapid change in the rectal pressure.

An object of the present invention is to solve the above problems,
It is an object of the present invention to provide a defecation treatment device having a mechanism capable of constantly detecting the pressure state inside the rectum and automatically performing an intestinal washing, crushing or suction treatment according to the situation and controlling the pressure within a set pressure range.

[0007]

In order to achieve the above object, the defecation treatment device according to the present invention has an irrigation means for intestinal lavage fluid by inserting an inserter equipped with a horn that causes mechanical vibration into the rectum through the anus. In a device for excretion and removal of feces through suction means of crushed feces, a pressure sensor for detecting internal pressures on the irrigation side and the suction side, and an irrigation pump, a suction pump and a vibration source that receive a signal from the pressure sensor. The structural feature is a mechanism including a pressure control unit for activating / deactivating the driving unit.

In addition to this structure, a mechanism is provided in which a temperature sensor is attached to the distal end of the insertion tool and a signal from the temperature sensor is transmitted to a heat exchanger for controlling the temperature of the intestinal cleansing fluid via a temperature controller. Then, it becomes possible to inject an intestinal fluid equivalent to the body temperature into the rectum, which further reduces the discomfort of the patient.

[0009]

According to the apparatus of the present invention having the above-mentioned structure, the pressure sensor installed in the system captures the internal pressure states on the irrigation side and the suction side, and transmits the signal to the pressure control section. The pressure control unit automatically stops the irrigation pump and the vibration drive unit at the time of overpressure out of a preset pressure range, and at the same time operates the suction pump to suck and remove feces to lower the internal pressure of the rectum.
On the other hand, when the pressure is lower than the set pressure range, the suction pump is stopped and the irrigation pump is activated to increase the rectal internal pressure and input it to the vibration drive unit to vibrate the horn.

Due to such an action, the rectal internal pressure which fluctuates during the excretion treatment process is automatically adjusted within an appropriate range, so that the phenomena such as damage to the rectal tissue and the pain and discomfort of the patient are effectively eliminated. Therefore, it becomes possible to proceed the defecation process safely and smoothly.

[0011]

Embodiments of the present invention will be described below in detail with reference to the overall configuration diagram shown in FIG. Note that the same members as those in FIG. In FIG. 1, the solid line route indicates the piping lines on the irrigation side and the suction side. The piping line on the irrigation side is connected to the irrigation nipple of the insertion tool 1 through the intestinal fluid container 3, the irrigation pump 5, the heat exchanger 12, and the irrigation chamber 13 by the irrigation pipe 6. The piping line on the suction side enters the storage container 8 from the insertion tool 1 through the suction pipe 7 and the suction chamber 14, and the storage container 8 is provided with a vacuum pump type suction pump 9 for holding a reduced pressure inside the container. It is connected. Adjustment of the degree of pressure reduction is performed by a pressure regulating valve 15 which is installed branching from a pipe leading to the suction pump 9. Further, a branch pipe 16 connecting the irrigation pipe 6 and the suction pipe 7 is connected between the downstream position of the irrigation pump 5 and the upstream position of the suction chamber 14. The pinch valves 17, 18, and the irrigation pipe 6, the suction pipe 7, and the branch pipe 16, respectively
19 are installed. These pinch valves have a mechanism that can be reliably clamped.

The material of the irrigation pipe 6, the suction pipe 7, the branch pipe 16 and the like which compose the piping line is preferably soft polyvinyl chloride or silicone resin. The irrigation chamber 13 and the suction chamber 14 are not limited in type as long as they are hollow containers made of transparent resin whose contents can be observed.
Further, the storage container 8 is made of a material having a bottle shape and having a strength capable of withstanding reduced pressure.

In FIG. 1, the route shown by the broken line is the sensing line, and the route shown by the alternate long and short dash line is the control signal line. Among these, the pressure control mechanism, which is the main component of the present invention, is connected to the irrigation chamber 13 and the suction chamber 14 and the pressure sensor 20 by a pipe, and the signal captured by the pressure sensor 20 is generated by the pressure control unit 21. A control signal for operating / stopping is transmitted to a drive unit 24 of a vibration source that vibrates the irrigation pump 5, the suction pump 9 and the insertion tool 1 within a pressure range preset by a control function. At this time, the irrigation chamber 13 and the suction chamber 14 function as sites for monitoring the rectal internal pressure. Installed pressure sensor 20 is -760 ~ 760mmH
It suffices that it can measure in the range of g, and the type may be a gauge type or a differential pressure type. However, it is preferable to use a differential pressure type that can measure both positive and negative pressures with reference to atmospheric pressure.

The temperature control mechanism is for adjusting the temperature of the intestinal cleansing fluid to a temperature suitable for injecting it into the body, and the temperature control unit 23 receives a signal detected by the temperature sensor 22 attached to the distal end portion of the insertion tool 1. Convert to a proper temperature control signal with the heat exchanger 12
Communicate to. The temperature sensor 22 may be of any type as long as it has a function of converting temperature into an electric signal, but a small one such as a thermistor or a thermocouple is suitable for the purpose of the present invention. The control mechanism of the temperature controller 23 is, for example, O
It can be configured by N-OFF control, PID control, fuzzy control, or the like. The heat exchanger 12 performs a temperature control function of cooling the intestinal juice when it rises too much due to the heat generated by the vibration of the horn, and heating the intestinal juice during the injection before the vibration, and its mechanism is a heater and a compressor. However, it is preferable to use an electronic cooling / heating system that utilizes the Peltier effect, which can perform cooling and heating depending on the direction of the current.

At the stage of irrigation and vibration crushing during the defecation process, the pinch valve 17 is open and both pinch valves 18 and 19 are closed. In this state, the intestinal cleansing fluid is supplied by the irrigation pump 5 and enters the heat exchanger 12,
The irrigation chamber 13 is adjusted to the proper temperature here.
And is injected into the rectum from the distal end portion of the insertion tool 1 through. Then, the drive unit 24 is operated to apply ultrasonic vibration to the horn 2 of the insertion tool 1. The rectal pressure is detected by the pressure sensor 20 inside the irrigation chamber 13 that functions as a monitoring unit. When the detected pressure exceeds the upper limit of the preset pressure range, the irrigation pump 5 and the drive unit 24 are stopped by the control signal from the pressure control unit 21, and at the same time, the suction pump 9 is activated to remove the suction. To reduce rectal pressure.

In the suction stage, the pinch valve 18 is opened, and the pinch valve 17 is opened when the intestinal fluid is supplied and closed when it is not supplied. Regulator valve
The pressure is adjusted at 15, and the suction pump 9 is operated to suck and collect the crushed feces and the intestinal juice in the rectum in the storage container 8. At this time, the rectal internal pressure is measured by detecting the internal pressure of either the irrigation chamber 13 or the suction chamber 14 with the pressure sensor 20, because neither the irrigation side nor the suction side is open to the outside. When the detected pressure falls below the lower limit of the set pressure, the control signal from the pressure control unit 21 stops the suction pump 9, and at the same time operates the drive unit 24 and the irrigation pump 5 to supply the intestinal cleansing fluid to increase the rectal pressure. Raise to the proper range.

When undigested seeds or the like are clogged at a site such as the suction part of the insertion tool 1 during suction, the phenomenon can be detected by the difference in internal pressure between the irrigation chamber 13 and the suction chamber 14. When a blockage is detected, the pinch valves 17 and 18 close and the pinch valves
19 is opened, and the intestinal cleansing fluid flows in through the branch pipe 16 to remove seeds and the like.

Such an intestinal cleansing, crushing and suctioning process is automatically repeated to promote a smooth defecation process.

[0019]

As described above, by using the defecation treatment apparatus according to the present invention, it becomes possible to automatically control the rectal pressure that fluctuates at the stages of irrigation and suction during defecation treatment within an appropriate range. Therefore, the rectal damage and the pain and discomfort experienced by the patient, which are seen in the conventional device, are eliminated, which is extremely useful in the medical industry.
