BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excrement disposal device for inserting into the rectum of a patient with dysfecation or the like and smoothly and safely shaving and removing stool.

[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, despite the fact that excrement treatment is a major problem in daily life, only a urine collector has been developed as an excretion device, and a laxative for fecal excretion treatment still remains, A method of encouraging defecation by enema or excision 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. (JP-A-1-198540 and JP-A-21985)
-218362).

According to the excretion treating apparatus according to these prior arts, it becomes possible to rapidly and smoothly proceed the excretion treatment even for the hard feces of patients with dysfunction of defecation and the like. However,
During excretion, the tip of the crushing insert tool vibrates and sucks at the same time.Therefore, if the tip of the crushing insert tool contacts the rectal wall, the rectal wall may be damaged by mechanical vibration or the temperature may rise. May get burned,
There is also the risk of the rectal wall being sucked into the insert and damaged due to the suction effect.

The inventors of the present invention have provided an excretion treatment device with a pressure sensor having a mechanism for preventing such a situation, detecting the pressure state inside the rectum, and automatically controlling the intestinal washing, crushing or suction treatment according to the situation. Proposed as Japanese Patent Application No. 3-15851 and Japanese Patent Application No. 3-352457.

DISCLOSURE OF THE INVENTION According to the present invention, when the electrical load state at the tip of the crushing insertion tool is taken as a difference signal of acoustic impedance, it is possible to discriminate between the rectal wall and feces without attaching a pressure sensor as described above. It has been clarified that it will be possible to develop.

Therefore, an object of the present invention is to accurately identify feces or rectal wall by utilizing the sensing function of the crushing inserter itself, and the horn vibration, suction pressure,
An object of the present invention is to provide an excretion treatment device with a fecal detection device having a mechanism capable of always crushing and sucking away solid feces by safely and efficiently controlling the flow rate of intestinal fluid and the like.

[0008]

In order to achieve the above object, an excrement disposal device with a feces detecting device according to the present invention is provided with a crushing insert having a vibrator and a horn for oscillating mechanical vibration from the anus to the rectum. In the device for excretion and removal of feces from the body through the means for supplying an intestinal fluid and the suction means for crushed feces, a stool detection circuit for detecting an electrical load applied to the crushing insertion tool, and a stool detection circuit A mechanism that transmits a signal to a high-frequency oscillation circuit that controls horn vibration via an oscillation control circuit, and a mechanism that transmits a signal from the fecal detection circuit to a suction pressure adjusting valve and an opening / closing valve via a suction pressure control circuit, And a mechanism for transmitting a signal from the fecal detection circuit to the supply pump via the intestinal fluid flow rate control circuit.

[0009]

According to the apparatus of the present invention having the above-mentioned structure, the electrical load state such as the voltage and the current applied to the vibrator is first captured in the vicinity of the tip of the crushing insert during excretion processing in accordance with the change in the acoustic impedance. By doing so, it is possible to identify whether the object contacting the tip of the crushing insert is feces or the rectal wall. The identification signal is converted into a predetermined electric signal by the feces detection circuit and transmitted to each system of oscillation control, suction control and intestinal fluid flow rate control. In the oscillation control system, the signal from the fecal detection circuit is transmitted to the high-frequency oscillation circuit via the oscillation control circuit, and when the tip of the crushing insert comes in contact with the rectal wall, the degree of horn vibration is adjusted to damage the rectal wall. Control to a vibration state that does not give In the suction control system, the signal of the fecal detection circuit is transmitted to each valve connected to the suction pump via the suction pressure control circuit, and the suction degree is controlled so that the phenomenon that the rectal wall is sucked into the crushing inserter does not occur. Further, in the flow rate control system of the intestinal fluid, the signal of the fecal detection device gives an instruction to the supply pump via the flow control circuit for the intestinal fluid to adjust the supply amount of the intestinal fluid so that the inside of the rectum has an appropriate internal pressure level.

As described above, in the present invention, in addition to the functions of the crushing inserter such as the stool crushing, the supply of the intestinal fluid and the suction removal, the function of the sensing function utilizing the acoustic impedance of the tip portion is accompanied by the identification of the stool or the rectal wall It is possible to control each system. Therefore, it is possible to effectively eliminate the phenomena such as the pain and discomfort of the patient due to the damage or inhalation of the rectal wall without providing a special sensor, so that the defecation process can always proceed safely and smoothly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the illustrated embodiments. The crushing insert 1 attached to the excrement processing device with a feces detecting device of the present invention has substantially no difference from the conventional one, and has a structure as shown in FIG. 1 (a side view having a partial cross section showing the whole). It is a thing. The main body has a wide-diameter vibrator cover portion 2, a protective cover 3 that is continuously provided via a taper portion in the front axis direction, and a back cover 6 that attaches an irrigation nipple 4, a vibrator cable 5 and the like to the rear end portion. The vibrator cover 2 has a vibrator built therein, and the horn 7 is set in the center of the protective cover 3. A suction nipple 9 communicating with a suction / removal passage 8 for discharging crushed feces is installed in the taper portion, and an intestinal fluid supply hole communicating with the irrigation nipple 4 through the vibrator and the horn 7 is provided on the central axis. It has a formed structure.

The protective cover 3 is made of, for example, plastic, synthetic rubber or
It is formed of natural rubber or a combination of these materials. Further, it is preferable that the vibrator cover portion 2 is also made of the same material. As a mechanism of the vibrator, a vibration method using various elements such as a cam type or an unbalanced mass rotation type driven by a mechanical motor, an electric piezoelectric type, an electrostrictive type, a magnetostrictive type, and an electromagnetic type can be applied. There is no particular limitation. The material of the horn 7 is made of a metal such as stainless steel, aluminum alloy such as duralumin, or titanium alloy, which has high corrosion resistance and excellent toughness that does not absorb vibration.

According to the present invention, in the above-mentioned crushing insert 1,
It is characterized in that it captures the electrical load applied to the vibrator to form a sensor mechanism. Since the feces, the rectal wall, other internal tissues, residual substances in the body, and the like have their own acoustic impedances, the electrical load applied to the oscillator of the crushing insert during high frequency oscillation differs depending on the substances interposed near the tip. There is no limitation on the type of electrical load to be captured, for example, the phase difference between the current and voltage applied to the vibrator, frequency, current value,
The voltage value, power value, etc. are targeted. By capturing such an electrical load and converting information such as whether stool is present near the tip of the crushing insert or whether the rectal wall is in contact with it into an oscillation control system, a suction control system and an intestinal fluid flow control system. introduce.

FIG. 2 is an overall constitutional view of the excrement processing device with a feces detecting device according to the present invention. From the feces detecting circuit 10 for converting the electric load captured by the vibrator of the crushing insert 1 into a predetermined electric signal, Oscillation control system of path 11, suction control system of path 12,
It is configured to branch to the flow control system of the intestinal cleansing fluid on the route 13.

The oscillation control system is a system for mechanically vibrating the oscillator of the crushing insert 1, and an electric signal from the feces detection circuit 10 is an ultrasonic wave generated by the high frequency oscillation circuit 15 after being controlled by the oscillation control circuit 14. Adjusts the amplitude and turns on / off. With this function, when there is no feces at the distal end of the crushing insert 1, the vibration of the horn 7 is stopped or the amplitude is reduced to prevent damage to the rectal wall.

The suction control system is a system for sucking and removing the crushed feces outside the body, and the suction nipple 9 of the crushing insert 1 is used.
A suction pressure control circuit connected to the path 12 from the suction tube 16 connected to the suction tube 16 through the opening / closing valve 17, the storage container 18, and the suction pressure adjusting valve 19 to the suction pump 20.
It is formed by interposing 21. Therefore, the suction pressure control circuit that receives the electric signal from the feces detection circuit 10
On / off valve 17 for suction removal on / off according to the instruction from 21
However, the suction pressure adjusting valve 19 adjusts the suction pressure. This function prevents the situation where suction is stopped or the suction pressure is lowered and the rectal wall is sucked into the crushing inserter in a state where the tip of the crushing inserter 1 contacts the rectal wall.

The intestinal fluid flow control system is a pump for supplying an intestinal fluid container 22 filled with an intestinal fluid such as water or physiological saline.
23 (Roller pump) to form the intestinal cleansing fluid through the heat exchanger 24 through the irrigation tube 25 and the route for connecting the irrigation nipple 4 of the insertion tool 1 to the cleaning fluid flow control circuit 26 connected to the path 13. Has been done. The control of this system is performed by a mechanism in which the supply pump 23 adjusts the flow rate by the operation of the intestinal fluid flow control circuit 26 which receives a signal from the fecal detection circuit 10. With this function,
Extreme changes in internal pressure inside the rectum are suppressed, and patient distress and discomfort are effectively reduced.

The process of removing feces using the excrement device with a feces detecting device of the present invention is usually a step of supplying an intestinal fluid in which the intestinal fluid is ejected with the tip of the crushing insertion tool 1 inserted from the anus into the rectum. Then, an ultrasonic wave oscillating step in which the horn is vibrated in parallel with the supply of the intestinal fluid and a suction removal step of finally removing the crushed and water-solubilized feces outside the body are set as one cycle, and a procedure of repeating this is adopted. At which stage the feces should be detected in this processing stage is appropriately determined depending on the situation, but there is a preferable way to deal with the detection stage.

First, when feces are detected immediately before the start of excretion processing, ultrasonic oscillation for feces detection is performed immediately before the start of the first cycle, and when feces are detected, the excretion processing is started and the rectal wall is started. If this is detected, a warning is issued to reconfirm the insertion position of the crushing insert or the excretion process is stopped. Also, when performing fecal detection immediately before the start of each stage or just before the start of the designated stage,
If ultrasonic wave is generated to detect feces and feces are detected, each step is started, and if rectal wall is detected, a warning and / or excretion to reconfirm the insertion position of the crushing insert Pauses or interrupts processing.

If fecal detection is to be performed during each stage of processing, the following is performed. During the supply of cleansing fluid, ultrasonic wave oscillation for fecal detection was performed during the whole process or instantaneously in parallel with the supply of cleansing fluid, and when fecal matter was detected, this process was continued and the rectal wall was detected. In this case, the warning and / or the process is temporarily stopped or interrupted as described above. During the steps of supplying the enema fluid and ultrasonic oscillation, ultrasonic oscillation for fecal detection is performed during the whole process or instantaneously, and when feces are detected, the processing is continued or the oscillation amplitude is increased to increase the crushing force. When the rectal wall is detected, the same warning and / or temporary suspension or interruption of the processing are performed. During the suction removal step, ultrasonic oscillation for fecal detection is performed during the whole process or instantaneously in parallel with suction removal, the processing is continued when feces are detected, and the above is performed when rectal wall is detected. Similar warnings and / or suspension, interruption, or reduction of suction pressure to prevent rectal wall inhalation.

As described above, since feces can be detected at all stages of processing and each stage, full-time, real-time feces detection and feces detection at any stage can be appropriately selected through the process of excreting all feces.

[0022]

As described above, by using the excretion treatment device according to the present invention, the horn vibration can be started / stopped or controlled within an appropriate amplitude range depending on the contact state between the tip of the crushing insert and the feces or the rectal wall. At the same time, it becomes possible to suck and remove feces while keeping the suction pressure of crushed feces at a safe level. In addition, the operator can know in real time whether the contact target of the fracturing insert is feces or the rectal wall. Therefore, the mechanical vibration in the state where the distal end of the crushing insertion tool is in contact with the rectal wall, which is a problem in the conventional device, and the rectal damage associated with suction removal, the pain and discomfort experienced by the patient, etc. are eliminated. It is extremely useful in industry.
