Wheelchair bed with functions of full posture changing and defecation cleaning

Abstract

A wheelchair bed with functions of full posture changing and defecation cleaning comprises a bed body and a defecation cleaning system. Bed boards are longitudinally composed of three sections, and each section is horizontally divided into a left part, a middle part and a right part. Adjacent edges of the bed board parts are hinged together. The top of each of a center bearing bracket, a back bed board bracket and a leg bed board bracket is hinged to the bottom of each of the buttock bed board section, the head and back bed board section and the leg bed board section. The bottom of each of a rollover electric cylinder, a back lifting electric cylinder and a leg curving electric pull rod is connected with the bottom of the center bearing bracket, while the top of each of the rollover electric cylinder, the back lifting electric cylinder and the leg curving electric pull rod is hinged to the buttock bed board section bottom, the back bed board bracket and a leg curving slider. One end, close to a bedside, of the center bearing bracket is hinged to a base, while the other end thereof is pressed on the base. Two ends of a vertical horizontally-lying electric cylinder are respectively hinged to the base and the center bearing bracket. The bed board sections on the left and right are connected with brackets under the bed board through side supporting rods. A chamber pot, a defecation storage box, a water-storage box, and the like are mounted in the bed body. The wheelchair bed with the functions of the full posture changing and the defecation cleaning is good in stability and safe to use, and easy to move since frames of a bedstead disappear when the wheelchair bed is used as a wheelchair.

Description

technical field [0001] The invention relates to a wheelchair bed with functions of fully changing posture and defecating, and belongs to the technical field of medical nursing beds. [0002] Background technique [0003] At present, there are many types of medical nursing beds on the market, most of which have single functions, such as turning over, bending legs, sitting up, pituitary supine and heart lying, and nursing beds with functions of defecation, cleaning, drying and deodorizing. few. Some existing nursing beds have the function of standing up, rolling over and defecating, but there are many key shortcomings in usability and safety. For example, the Chinese patent No. 200920011127.8 discloses a medical bed, which adopts an oil cylinder as a posture-changing drive mechanism. Although it can realize various posture-changing functions, the structure is relatively complicated, and it is difficult to install a toilet cleaning system; leaks are prone to occur during use....

Problems solved by technology

[0003] At present, there are many types of medical nursing beds on the market, most of which have single functions, such as turning over, bending legs, sitting up, pituitary supine and heart lying, and nursing beds with functions of defecation, cleaning, drying and deodorizing. few

There are some existing nursing beds with the functions of standing up, rolling over and defecation, but there are many key shortcomings in terms of usability and safety.

For example, the Chinese patent No. 200920011127.8 discloses a medical bed, which adopts an oil cylinder as a posture-changing drive mechanism. Although it can realize various posture-changing functions, the structure is relatively complicated, and it is difficult to install a toilet cleaning system; leaks are prone to occur during use. Oil pollutes the environment of the ward, and the control accuracy is relatively poor

The Chinese patent No. ZL201020573578.3 discloses another electric medical nursing bed, which also has multiple posture changing functions such as turning over and sitting up. The structure is more advanced than the 200920011127.8 patent, and there is no oil pollution. The frame still exists, which makes it inconvenient to move; when turning over, the sitting position changing mechanism under the bed board swings left and right, which is easy to hurt people

In addition, the existing nursing beds with a defecation system generally have the following problems: the toilet is directly connected to the indoor sanitary pipeline, or connected to an independent suction cleaning machine, so that the bed is inconvenient to move; When the toilet is raised to the height of the bed surface, the structure is more complicated, which will affect the installation of the cleaning pipe and other driving mechanisms; there is no anal gasket at the defecation opening, and the anus cannot be separated naturally during defecation and cleaning, and it is difficult to clean; there is no toilet cover, flat It is easy to stain the bed sheet when lying down; the warm water washing device cannot be moved and adjusted, and cannot adapt to different sizes of human bodies and defecation positions
