Description

Intelligent electric control toilet auxiliary device

Technical Field

The invention relates to the technical field of medical instruments, in particular to an intelligent electric control toilet assisting device.

Background

Old person, the weak patient (including internal medicine, surgery postoperative patient etc.), because reasons such as ageing, disease, when like the lavatory, especially on squatting accomplish the stool pot, when standing up, take place the unstable and fall down that leads to of standing, usually in order to solve this problem, often need medical personnel or family members to accompany, greatly increased like the psychological burden of lavatory crowd, also indirect simultaneously causes unnecessary trouble (like the smell like the lavatory to cause unnecessary influence to the surrounding environment) for medical personnel and family members.

At present, in the prior art, the handrails and the chairs are mostly adopted to assist the patient to go to the toilet; the armrests of the patient chair cannot meet the requirements of all patients, particularly for the elderly and the infirm patients, and the hand strength of the patients cannot fully guarantee the body stability of the patients when the patients squat and stand; while another chair or wheelchair, when in use, will be pushed into the toilet and is only suitable for patients who cannot walk, stand, but not for patients who can walk.

In order to facilitate the defecation, a part of hospitals can also modify a seat or a wheelchair into a toilet bowl to realize two functions of the toilet bowl and the seat, and compared with an independent and private space such as a toilet, the defecation on the seat or the wheelchair has psychological barrier for many people. Therefore, the falling-down of the old and the weak patients during the toilet is prevented, so that the economic burden of the patients, families and society is relieved; simultaneously, let old person and the patient that can the initiative activity, can be safe like the lavatory by oneself, promote this crowd's self-care ability and quality of life, provide one kind specially and alleviate nursing staff's physical burden, reduce the handicapped person mental disorder, the patient of being convenient for is like the automatically controlled auxiliary device that like the lavatory of intelligence of lavatory.

Retrieving the current patent application: CN107997667A discloses a toilet support, belonging to the technical field related to medical appliances. The method mainly comprises the following steps: an upper layer framework; the upper layer framework is connected with the middle layer framework through a connecting rod; the middle layer framework is connected with the lower layer framework through a connecting rod; universal wheels are mounted at the lower part of the lower layer framework; the universal wheel comprises a main support, a limiting frame is connected to the inner side of the main support, a steering shaft is inserted into the limiting frame, the lower end of the steering shaft is fixedly connected with a roller frame, and a roller is mounted on the roller frame; and a spring is sleeved on the steering shaft and positioned between the limiting frame and the roller frame. The device can make the independent action of squatting and rising of completion on the closestool of patient, makes the patient can be like the lavatory independently under the prerequisite that does not have other people's help. But the whole use is inconvenient, can't carry out the upper and lower activity regulation to strutting arrangement, and the universal wheel of bottom is fixed unstably, causes unnecessary injury to the patient easily.

The patent application: CN112168513A discloses a wheelchair like lavatory, relates to the medical instrument field, including the wheelchair main part, be equipped with the side riser that bedplate and symmetry set up in the wheelchair main part, the geometric centre position of bedplate is equipped with like the lavatory hole, like be equipped with the backing plate in the lavatory hole and be used for not using when like the lavatory hole with it shutoff, the below of bedplate is equipped with rotary mechanism and is used for rotatory whole bedplate, be equipped with backing plate displacement mechanism respectively on the side riser and be used for putting aside the backing plate when like the lavatory, the four corners position symmetry of side riser is equipped with lifting air bar and is used for the lifting bedplate, and the device can be when the user like the lavatory by user front drive make whole seat position move to the closestool top, and the rethread overturns whole seat and realizes that the user alone can like the lavatory with the backing plate to the mode of opening is moved to both sides to set up lifting mechanism in the wheelchair both sides, can lift user's upper part of the body from user's armpit, and convenience of user goes the clothing, facilitates the use. However, the wheelchair structure of the device is easy to cause psychological disorders to patients, and meanwhile, medical care personnel are required to push the device into a toilet, so that the device is complex to operate and inconvenient to use, and the workload of the medical care personnel and family members is increased.

Therefore, in summary, there is a need for an intelligent electronic control toilet assisting device which is easy to operate, convenient to use, and capable of facilitating the self-control of a patient in toilet and improving the safety and stability of the patient in toilet, but no report is found about the intelligent electronic control toilet assisting device.
