BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to an excretions treating apparatus which can extract and remove excrements from a rectum of an inevacuative patient.
2. Background Art
A patient who needs a certain excretions treatment (to be called "a patient" hereinafter) has been treated with a laxative, a clyster, an anal stimulus and the like according to the condition of the patient. On the other hand, as to the inevacuative patient, a high pressure clyster, a removal of excrements, a suppository or the combination thereof has been applied. The condition of "inevacuative" means that it is impossible to evacuate without help of other person.
However, the above-described treatments arise the following problems.
In the high pressure clyster, a catheter and a large-sized-syringe are used to inject medical fluid into a patient's rectum through his anus so as to stimulate evacuation. However, in this case, there is a fear that a rectum wall is damaged In addition, if excrements is hard, the high pressure clyster cannot demonstrate its ability effectively, with the result that the evacuation cannot be fully conducted. Furthermore, it takes a too time to do this treatment, whereby the patient is considerably physical suffering.
In the removal of the excrements, fingers with a sanity glove worn are inserted directly through patient's rectum to scrape out the excrements. However, if excrements is hard, it is difficult to scrape them out completely, with the result that the evacuation cannot be fully conducted. In addition, there is a fear that a mucous membrane on the patient's rectum is damaged.
Suppository is almost useless for hard excrements.
In order to overcome the above-described problems, a suction type excretions treatment apparatus has been proposed, which is one of high pressure clyster methods (JP-A-61-293472). In this suction type excretions treatment apparatus, there are provided an outer pipe and a guide pipe which is slidable within the outer pipe. After the outer pipe has been inserted into the patient's rectum, the guide pipe is extended into the patient's rectum beyond an end portion of the outer pipe, and then the medical fluid is injected there through into the patient's rectum. After the excrements has been softened, the guide pipe is retracted to open the end portion of the outer pipe Then, the thus-softened excrements are extracted from the opened portion of the outer pipe by a vacuum pump into an external reservoir tank through the outer pipe.
However, since the excrement is softened simply by the medical fluid, this apparatus could not demonstrate its ability effectively for hard excrements.
DISCLOSURE OF INVENTION
Accordingly an object of the present invention is to provide an excretions treating apparatus which can solve these problems and is capable of a effective and safe full evacuation.
To this end, according to the present invention, an excretion treating apparatus comprises crushing means for crushing excrements by mechanical vibrations caused by ultrasonics, and extracting and excreting means for excreting the crushed excrements outside the patient's body.
According to another aspect of the present invention, an excretion treating apparatus comprises, in addition to the crushing means and the extracting and excreting means, medical fluid injection means for injecting medical fluid into excrements in the rectum to soften it.
According to the crushing means, even if the excrements is hard, it can be crushed and extracted readily and fully.
Then, a preferred embodiment of the present invention will be described hereinunder with reference to the accompanying drawings:
