Description
Technical field
The utility model is related to technical field of medical instruments, more specifically a kind of controllable backboard release of production sick bed speed
Device.
Background technology
The sick integration bed backboard of production in the market all has CPR functions, that is, requires that the backboard that patient is lain can be fast
Being laid flat for speed, promptly does CPR to patient.But this quick release has lied on a bed due to occurring in patient
Situation, so too fast speed can cause serious impact and cause unnecessary injury to patient particularly puerpera.Therefore it is right
Speed control during backboard quick release also becomes an important research project of CPR functions.
The mainstream scheme to speed control is to do damping due to rotation in the electric pushrod of driving backboard motion at present, so as to reach
Decrease speed of the control nut along screw mandrel when opening is switched to electric pushrod quick release.But it is due to that use this is electronic to push away
Bar needs to cause the order cycle time long from external import, and price is high, so as to bringing many inconvenience using producer.
There is a kind of electric pushrod with fast release function in the market, because this electric pushrod is in fast quick-release
When putting opening, only rely on the frictional force between feed screw nut to prevent the motion of push rod, thus backboard can not be controlled well
Decrease speed, and when the load down on backboard, backboard can be caused faster to decline.
The content of the invention
To solve the above problems, overcoming the deficiencies in the prior art, the utility model, which intends offer one kind, can be rapidly completed the back of the body
Plate falls to requiring, without because of the too fast controllable backboard release device of production sick bed speed damaged to patient of falling speed.
To achieve the above object, the controllable backboard release device of production sick bed speed that the utility model is provided, including backboard, frame
Frame, damper rod, electric pushrod, lower gas spring, upper gas spring, upper hopper chute, gliding groove;Backboard is under one end of frame mid portion
