It applies medicinal lotion or ointment to doctor or when suture needle when the arm of patient needs are stretched, doctor first controls motor clockwise or the inverse time
Needle rotation, motor rotation move up or down the second N-type frame by the cooperation of screw rod and threaded hole, when the second N-type frame to
When lower mobile, contacted at the top of mandril and the first N-type frame, the first spring works as a buffer, and can so adjust the height of U-shaped frame
Degree after regulating height, closes motor.Doctor pulls up the first link block, and mobile connecting rod also moves up on the first link block,
Then arm is placed in U-shaped frame by patient, then decontrols the first link block, and arc pressuring plate is made to push down arm, then doctor start for
The arm of patient is applied medicinal lotion or ointment or suture needle.After applying medicinal lotion or ointment or suture needle is completed, pulling up the first link block makes arc pressuring plate and hand
Arm does not contact, and then takes out arm.
When the second N-type frame moves up, the second hook is not contacted with the first hook, and such framework can be in second spring
Elastic force effect under move right, then will apply medicinal lotion or ointment or the drug of suture needle needs and object be put into framework.Use completion
Framework is pushed back again afterwards, then starts motor and rotates clockwise, motor, which rotates clockwise, drives screw rod rotation, and screw rod rotation makes the
Two N-type framves move down, and the second N-type frame, which moves down, makes the first hook tangle the second hook, hang over the second extension when first
Motor is closed after on hook.So facilitate doctor to facilitate at work and takes required object.
When framework moves right or is moved to the left, pulley slides in second sliding slot, abrasion when preventing framework from moving left and right.
When arm is put into U-shaped frame, arm is placed on protection pad, since arm has weight, protection pad can be made to move down, and
The 5th spring is compressed, is worked as a buffer.After doctor wipes medicine or stitched needle, the arm of patient is taken away, and protection pad is in the 5th bullet
The elastic force effect of spring is lower to be resetted.The arm of patient can so put more comfortable.
Beneficial effects of the present invention: the present invention is rotated by motor, and motor drives screw rod rotation, and screw rod is matched with threaded hole
It closes, to drive the second N-type frame to move up, to adjust the height of U-shaped frame and its upper-part, to adapt to patient
Height, and also protect the arm of patient using protection pad, while be also placed on arm comfortably on protection pad, mitigate pain
Sense.
