When patient needs using the present invention, after medical staff bandages patient, suspender belt is first hung over to the neck of patient
Or on shoulder, then top shoe is skidded off out of upper sliding rail again, top shoe drives fixing belt to skid off, and then can be by the large arm of patient
It is put into bracket, then again slides into top shoe in upper sliding rail, and then fixing belt can fix the large arm of patient, then
The forearm of patient is put into supporting plate by medical staff, and the position of web plate is then adjusted according to the concrete condition of patient, works as needs
When adjusting the position of web plate, medical staff first extracts inserted link out of aperture, and the first spring is stretched, then by arc shaped slider in arc
It is slided on shape sliding rail, then medical staff can be adjusted, and after medical staff is adjusted in place, medical staff, which unclamps, to be inserted
Bar, inserted link are inserted into aperture under the spring-force driven dual of the first spring, so that the position of web plate is fixed, it so can be effective
Prevent patient there is a situation where accidentally encountering wound, while web plate is only protected on the outside of wound, gas permeability is preferable, ventilation effect
Fruit is good, is conducive to the recovery of wound, and last medical staff adjusts strainer and suspender belt is adjusted to suitable position, feels patient more
Comfortably, when needing dressing, medical staff only need to take out the forearm of patient out of supporting plate, then link block is rotated down, i.e.,
Dressing can be carried out, it is thus very convenient, it also will not influence the operation of medical staff, when patient is without the use of the present invention, medical care
Personnel take out the forearm of patient and large arm out of supporting plate and bracket respectively, then again by suspender belt from the neck or shoulder of patient
It removes, the effect of strut is two side's supporting plates of connection left and right, and the placement for the forearm of patient provides support.
In use, top shoe moves in upper sliding rail and is provided with cross bar and circular hole the present invention in order to prevent, when
When medical staff needs to move top shoe in upper sliding rail, medical staff presses down on vertical bar, and vertical bar stress moves down, the
Two springs are compressed, and wedge block is moved to the left under the action of vertical bar, and then cross bar is driven to be moved to the left, and third spring is pressed
Contracting, cross bar is deviate from out of circular hole therewith, and then medical staff can move top shoe, when moving in place, medical care people
Member no longer presses vertical bar, and vertical bar moves up under the spring-force driven dual of second spring, and second spring resets, and wedge block is in third
It moves right under the spring-force driven dual of spring, and then cross bar is driven to move right, third spring reset, cross bar is inserted into circle therewith
In hole, so that the position of top shoe be fixed, prevent top shoe from arbitrarily moving.
The present invention in use, when patient needs to adjust the position between forearm and large arm, first will by medical staff
The rotation of butterfly-type screw rod positive direction, and then screws out out of threaded hole, washer no longer with arc panel front contact, then medical staff be
The position of removable link block, so as to adjust until Patients' satisfaction, after adjustment, medical staff is anti-by butterfly-type screw rod again
Direction rotates, and then is screwed into threaded hole, thus make washer compress arc panel, position is fixed, the effect of pull rod be
Medical staff is facilitated to fix the position of arc panel when mobile link block, the effect of round bar is led for the movement of arc panel
To.
When needing dressing, medical staff first screws out butterfly-type screw rod out of threaded hole, washer no longer with arc prelaminar part
Contact, then pull pull rod to rotate clockwise arc panel, and then bar is snapped onto U-shaped piece, then medical staff can incite somebody to action
Link block rotates counterclockwise, and facilitates dressing, and after finishing changing medicine, pushing drawing rod rotates counterclockwise arc panel to medical staff again, gear
Bar is deviate from out of U-shaped piece, after then adjusting link block, then butterfly-type screw rod is screwed into threaded hole, the effect of elastic piece
It is by bar clamping.
The invention has the following advantages that the present invention is slided on arc-shaped slide rail by arc shaped slider, web plate can adjust
Position, web plate is placed in the side for being easy to happen and colliding with, then again fixes the position of web plate, can so be effectively prevent
Patient is there is a situation where accidentally encountering wound, while web plate is only protected on the outside of wound, and gas permeability is preferable, ventilation effect
It is good, be conducive to the recovery of wound, and the configuration of the present invention is simple, lighter weight is conducive to mitigate patient's burden, disk with connect
The connection of block rotary type is conducive to medical staff and carries out dressing, easy to operate.
