2. The process of inflating and deflating the air bag is completed manually, the automation degree is low, and in the inflating process, due to certain requirements on the air pressure value of the air bag, medical workers are required to grasp the inflation quantity, so that the operation process is troublesome, and a lot of working strength is increased for nursing staff who originally work busy.

Disclosure of Invention

The invention aims to solve the problems of the prior art and provides a medical defecation drainage device which solves the problems that the operation of the conventional defecation collector is troublesome and the local skin of the anus of a patient is easily damaged.

The purpose of the invention can be realized by the following technical scheme: the medical defecation drainage device is characterized by further comprising a control box and two connecting pipes, wherein the two air bags are arranged on the anal pipe at intervals along the length direction of the anal pipe, the two connecting pipes are connected with the two air bags in a one-to-one correspondence mode respectively, an air pressure detection element for detecting the air pressure in the corresponding connecting pipes is arranged on each connecting pipe, an inflator pump, a controller and two vent pipes are arranged in the control box, the two vent pipes are communicated with the two connecting pipes in a one-to-one correspondence mode respectively, each vent pipe is communicated with the inflator pump through one inflator pipe respectively, an electromagnetic valve capable of controlling the on-off of the corresponding inflator pipe is arranged on each inflator pipe, an automatic exhaust valve capable of enabling the corresponding vent pipe to exhaust is arranged on each vent pipe, and the inflator pump, each air pressure detection element, the air pressure detection element and the air pressure detection element are, Each electromagnetic valve and each automatic exhaust valve are connected with a controller.

The working principle and the using method of the medical defecation drainage device are as follows:

when in use, the anal canal is inserted into the anus of a patient to a proper depth, and the two air bags on the anal canal are both in an uninflated state;

then, the controller controls one of the electromagnetic valves to be opened, the other electromagnetic valve is still in a closed state, the inflator pump starts to work, and gas sent by the inflator pump enters one of the air bags through the inflation tube, the vent tube and the connecting tube in sequence to inflate the air bag. In the process of inflating the air bag, the connecting pipe is always communicated with the air bag, so that the air pressure in the connecting pipe is detected through the air pressure detection element, the air pressure in the air bag can also be detected, when the air pressure value detected by the air pressure detection element reaches a set value, the air pressure detection element sends a signal to the controller, and the controller controls the opened electromagnetic valve to be closed and controls the inflator to stop working. At the moment, due to the action of the air bag, the anal tube can be positioned in the anus of the patient, and when the patient defecates, excrement can flow into the collecting bag through the anal tube and the drainage tube.

After the inflated air bag lasts for a period of time, the controller controls the other electromagnetic valve to be opened, and the electromagnetic valve opened in the previous step is kept in a closed state, so that the inflated air bag is prevented from being inflated again. Meanwhile, the controller controls the inflator pump to start working to inflate the other air bag. Similarly, when the airbag is inflated to a set air pressure value, the air pressure detection element corresponding to the airbag can also generate a signal to the controller, and the controller controls the electromagnetic valve corresponding to the airbag to close and the inflator pump to stop working.

And then, the controller controls the automatic exhaust valve corresponding to the first-time inflated air bag to be opened, and the gas in the first-time inflated air bag is discharged through the connecting pipe, the vent pipe and the automatic exhaust valve in sequence to realize deflation.

Obviously, this medical defecation drainage ware is through setting up two gasbags, in the use, through the gassing state of filling that switches two gasbags for the patient receives the position that the gasbag oppressed can be relaxed, consequently avoided when adopting single gasbag because the gasbag oppresses the problem that the skin ulcerate that the same position of patient anus caused all the time. Meanwhile, the process of inflation and deflation of the air bag and the process of air bag switching in the medical defecation drainage device can be controlled and finished by the controller, the degree of automation is higher, the problem of troublesome operation is avoided, and the working strength of medical personnel can be reduced.

In foretell medical drainage ware of defecation, be equipped with the exhaust branch pipe that has the gas vent on the lateral wall of breather pipe, on the inner wall of control box with the position that the gas vent is relative is equipped with and is cylindric guide part, automatically exhausting valve including fixed electro-magnet that sets up in the guide part with can by the absorbent sliding block of electro-magnet, the sliding block is located between electro-magnet and the exhaust branch pipe and the sliding block slides and sets up in the guide part, the sliding block is equipped with elastic sealed piece towards being equipped with on the side of exhaust branch pipe, the electro-magnet with be equipped with spring one between the sealed piece, spring one can the roof pressure sliding block remove and make sealed piece sealed towards the gas vent, can adsorb the sliding block and remove and open towards the direction of keeping away from the gas vent when the electro-magnet circular. A cylindrical guide portion is provided to guide the movement of the slide block and stabilize the movement of the slide block. When the controller control electro-magnet circular telegram, the electro-magnet can adsorb the sliding block and remove and open the gas vent towards the direction of keeping away from the gas vent, and the gas in the breather pipe can be discharged through the gas vent of exhaust branch pipe this moment to the realization is deflated corresponding gasbag. When the controller control electro-magnet outage, the sliding block alright reset under the effect of spring one, seal the gas vent.

In the medical defecation drainage device, the front side face of the control box is provided with the display screen, one end of each vent pipe penetrates out of the rear side face of the control box and is connected with the corresponding connecting pipe, and the other end of each vent pipe is further connected with the manual exhaust valve respectively.
