This application relates to the field of medical machinery, and for example, to a wearable working head of a nursing machine.
With the improvement of people's living standards, bedridden patients who are unable to take care of themselves with respect to urination and defecation due to e.g. cardiovascular and cerebrovascular diseases are increasing year by year, which brings great pressure on families and society. Because the patients cannot take care of themselves with defecation, they need the assistance of accompanying staff. The uncertainty of a patient's defecation times increases the workload of the accompanying staff, and also causes great pain and burden to the patient's physiology, especially his/her mental state. Therefore, medical institutions and patients' families often use a dedicated toilet nursing machine to automatically clean human excreta and also clean and dry the patients' lower bodies by a nursing machine main unit and a wearable working head.

Air outside the working head may be sucked in between the front wearing part and the human body through the air supplement pipeline 4, and the air is sucked out along with an excreta through a drain pipe. When the air pressure in the toilet recess 10 is a negative pressure with respect to the outside of the working head, the air outside the working head is supplied into the toilet recess 10 through the inner cavity 58 of the rear part and the air supplement pipeline 4 in sequence. The second end port 41 of the air supplement pipeline 4 may be located within the inner cavity 58 of the rear part. The air supplement pipeline 4 may be bent in the inner cavity 58 of the rear part, so it can prevent the excreta and cleaned water from leaking through the air supplement pipeline 4. Even if a small amount of the excreta or cleaning water may enter the air supplement pipeline 4, once the suction operation starts, the excreta or cleaning water would be able to be sucked out of the air supplement pipeline 4 through the air supplement port 40 and further out of the working head as long as there is no leakage. A part of the air supplement pipeline 4 may be bent upward in the inner cavity 58 of the rear part, or a part of the air supplement pipeline 4 may be bent leftward or rightward in the inner cavity 58 of the rear part. The air supplement pipeline 4 may include an outer bending section located outside the rear part, and two opposite ends of the outer bending section are each connected to the rear part. The outer bending section may have a shape of a hollow bent pipe. The outer bending section may include a left bending section 420 and a right bending section 421 that are joined together. The second end port 41 may be opened at the rear end wall right part 511 and forms an end port of the right bending section 421, the left bending section 420 may be connected to the rear end wall left part 510, the right bending section 421 may be connected to the rear end wall right part 511 and the left bending section 420 and the right bending section 421 are joined together in left and right orientation. The joint connection of the left bending section 420 and the right bending section 421 may be sealed. The right bending section 421 may be integrally connected to the rear end wall right part 511, and the left bending section 420 may be integrally connected with the rear end wall left part 510.
The air supplement pipeline 4 may include a first pipe section 430 integrally connected to the first housing 13, a second pipe section 431 integrally connected to the front side wall 50, and a third pipe section 432 integrally connected to the left bending section 420. The first pipe section 430 is joined with the second pipe section 431, the second pipe section 431 is joined with the third pipe section 432, the second pipe section 431 and the third pipe section 432 are arranged in the inner cavity 58 of the rear part, and the first pipe section 430 passes backwards through the front side wall 50 to enter the inner cavity 58 of the rear part.
It can also be designed that the second end port 41 of the air supplement pipeline 4 is directly communicated with the outside of the working head, and when the air pressure in the toilet recess 10 is a negative pressure with respect to the outside (when the nursing machine performs a sucking operation, the air pressure in the toilet recess 10 is a negative pressure relative to the outside), the air outside the working head may enter the air supplement pipeline 4 from the second end port 41 and be replenished into the toilet recess 10 through the air supplement port 40. The air supplement pipeline 4 may pass through the front wearing part to enter the rear part and then pass through the rear part, or the air supplement pipeline 4 may pass through the front wearing part to enter the rear part, and the second end port 41 of the air supplement pipeline 4 is opened in the shell of the rear part. The suction pipeline 95 communicating with the toilet recess 10 passes through the rear part, the excreta inlet 950 of the suction pipeline 95 is arranged at the rear wall 132, the excreta inlet 950 communicates with the toilet recess 10, the air supplement port 40 is located at a side lower part of the drying and blowing hole 98, and the air supplement port 40 is located at a side upper part of the excreta inlet 950.

The first urine sensors 96 and the second urine sensors 97 may be capacitive sensors. In an embodiment, it is necessary for all the first urine sensors 96 each to output the liquid detected signal or all the second urine sensors 97 each to output the liquid detected signal before the urine detection circuit outputs the urine signal. The liquid detected signal output by the first urine sensor 96 may be a low level, and the liquid detected signal output by the second urine sensor 97 may be a low level.

When more than one first urine sensor 96 outputs a liquid detected signal or when more than one second urine sensor 97 outputs a liquid detected signal, it may be regarded as that a urination is performed by the human body, which will trigger a disposal action of a human excreta, and when only one first urine sensor 96 outputs the liquid detected signal or only one second urine sensor 97 outputs the liquid detected signal or only one first urine sensor 96 and one second urine sensor 97 each output the liquid detected signal, it is regarded as that no urination is performed by the human body, thus the disposal action of the human excreta is not triggered. When more than one first urine sensor 96 outputs the liquid detected signal or when more than one second urine sensor 97 outputs the liquid detected signal, the urine disposing program of the nursing machine is triggered, and when only one first urine sensor 96 outputs the liquid detected signal or only one second urine sensor 97 outputs the liquid detected signal or only one first urine sensor 96 and one second urine sensor 97 each output the liquid detected signal, the urine disposing program of the nursing machine is not triggered.
