Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, this embodiment includes pressure sensors 1, 2, lever mechanism 3, driving roller mechanism 4, driven roller mechanism 5, stepper motor 6, single-chip microcomputer 7, positioning and clamping mechanism 9, displacement sensor 10, adjustable pressing Mechanism 11, bed body 12.

[0019] Each of the front supporting feet of the bed body is provided with a pressure sensor, and a front bracket is installed at one end of the bed body. A lever mechanism and an active roller mechanism are arranged on the front bracket, wherein the active roller mechanism is composed of a pair of friction cylinders 8. The first friction cylinder in the pair of friction cylinders is driven by a stepping motor, the second friction cylinder is mounted on one end of the lever mechanism, and the other end of the lever mechanism is equipped with an adjustable pressi...

Abstract

The invention discloses a gravity-controlled automatic bed sheet replacement system which comprises a pressure sensor, a lever mechanism, a drive roller mechanism, a driven roller mechanism, a step motor, a single chip, a positioning and clamping mechanism, a displacement sensor, an adjustable compaction mechanism and a bed body. When a patient lies on the bed body, the pressure sensor is stressed and outputs a corresponding analog signal, and the single chip is used for judging if the patient lies down for examination and leaves from an examining bed after examination according to signal jumping, so that the step motor is controlled to finish an automatic bed sheet replacement operation. The automatic bed sheet replacement system can be suitable for sickbeds with different widths, and is additionally configured on the basis of not changing the existing hospital sickbed structure to achieve full-automatic replacement of the bed sheets of the sickbeds.

Description

technical field [0001] The invention belongs to the field of auxiliary medical devices and relates to a gravity-controlled bed sheet automatic replacement system. Background technique [0002] For a long time, medical resources are in short supply, there are many patients, and the workload of medical staff is heavy. The time and manpower it takes to replace the mattress of the medical examination bed cannot be ignored during the examination process. In view of the above status quo, it is of great significance to provide a method based on the principle of pressure sensor weighing, using a single-chip microcomputer and corresponding control circuits to realize automatic replacement of the mattress of the examination bed. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a gravity-controlled bed sheet automatic replacement system. [0004] The invention includes a pressure sensor, a lever mechanism, a driving roller mec...
