Method for controlling linkage lifting of bottom board for supination table of bed or the like

Abstract

The present invention relates to a method for controlling the interlocking lifting and lowering of the floor of a supine platform such as a bed. In a supine platform having a back floor for lifting the back of a supine person and a knee floor for raising and lowering the knees of a supine person, each floor passes through In supine platforms such as beds that can be raised and lowered by separate lifting devices, it is characterized in that an external force detection device in the sliding direction is provided on the back bottom plate to detect the rise of the back bottom plate due to the rising state of the knee bottom plate. When the external force in the sliding direction is applied, all the base plates start from a lowered flat state, and when the back base plate is rotated and raised to form an inclined state, the knee base plate is also raised appropriately. At this time, when the external force in the sliding direction is detected by the above When the external force detected by the device in the sliding direction applied to the patient's back etc. rises to the set value, the knee floor is controlled to descend.

Description

technical field [0001] The present invention relates to a method for controlling the linkage lifting of supine platforms such as ordinary beds (hospital beds, ICU beds, household beds, etc.) and stretchers. In order to achieve the following purpose, the supine platform of the knee bottom plate of the knee portion is a linked lifting control method that makes the back bottom plate and the knee bottom plate rise and fall in conjunction. Background technique [0002] Supine platforms such as beds and stretchers are configured to have a back base for lifting the back of a supine person and a knee base for raising and lowering the knees of a supine, and the bases can be raised and lowered separately by separately provided lifting devices. [0003] As such a supine bed, there are many examples such as US Patent Nos. 5,469,591, 5,448,789, and 5,388,290. [0004] For example, the bed described in U.S. Patent No. 5,469,591 has a back base for raising and lowering the back of a supin...

Problems solved by technology

[0013] A. First of all, in method a, the supine person or the caregiver must simultaneously or alternately operate the driving devices of the back floor and the knee floor. The operation is very complicated and cumbersome and requires proficiency. It is difficult to optimally lift and lower the floor respectively

[0014] B. In the method b, due to the use of mechanical interlocking devices, the lifting state formed by the linkage of the back floor and the knee floor cannot be easily adjusted or changed, and it is difficult to effectively prevent the body from slipping and pressure. The Two Sides of Comfort

In addition, the back floor and the knee floor cannot be operated independently
