Abstract

The invention relates to the design improvement of a medical tool for transferring a wounded person. A mechanical hand for transferring the wounded person is provided with a male grabbing arm and a female grabbing arm, wherein the male grabbing arm and the female grabbing arm are respectively provided with a limiting plate and are respectively and fixedly provided with a grabbing hand, a convex plate on the male grabbing arm is placed in a groove in the female grabbing arm, a hole in the male grabbing arm is enabled to be aligned with a hole in the female grabbing arm, a through shaft is then arranged in a clearance way, and a tension spring is arranged between the male grabbing arm and the female grabbing arm. The mechanical hand is characterized in that the grabbing hands are manufactured made of high-strength engineering plastics, claws are in triangular wedge shapes, the thickness of the top end of each claw is 3 mm, each claw is in a smooth arc shape, and the thickness of each claw is 5 mm. The mechanical hand disclosed by the invention has the characteristic that the structure is simple, the use is convenient, safety and reliability are realized, and the like.

Description

A kind of sick and wounded's mechanical hand that shifts

Technical field

The present invention relates to medical treatment and shift the design improvement of sick and wounded's instrument, is a kind of sick and wounded of transfer mechanical hand.

Background technology

At present after medical surgery has been performed the operation, it is to rely on many people to complete in sick and wounded both sides hand rest mode from transferring to injuredly ambulance and operating-table that patient transfers to sick bed, the wounded from operating-table, this mode is not only very required great effort, and easily causes that because of carelessness the sick and wounded are painful and may cause secondary injury.

Summary of the invention

Object of the present invention will solve in medical operating sick and wounded treatment process exactly, and the sick and wounded shift inconvenience, takes people's effort, causes sick and wounded's secondary injury problem.

Concrete scheme of the present invention is: a kind of sick and wounded's mechanical hand that shifts, it has male gripping arm, female gripping arm, in male gripping arm and female gripping arm, be respectively equipped with a limiting plate, in male gripping arm and female gripping arm, fixedly mount respectively a handgrip with screw bolt and nut, male gripping arm convex platform is installed to female gripping arm upper groove, and ensure in male gripping arm on hole and female gripping arm that hole aligns, then gap installs axis, and between male gripping arm and female gripping arm, an extension spring is installed.It is characterized in that: handgrip is to be made up of high-strength engineering plastic, long L is 800～900 millimeters, and wide B is 250～300 millimeters, each handgrip is provided with 9～11 uniform claws, and claw is triangle wedge shape, thick 3 millimeters of top, smooth circular arc, thick 5 millimeters of end.

Use principle of the present invention is: male gripping arm and female gripping arm can be rotated arbitrarily and pull open around axis, when the mobile sick and wounded, only need pull open male gripping arm and female gripping arm, claw on handgrip inserts from sick and wounded's upper body both sides, in the time of limiting plate closing, in axis inner via hole, penetrate round bar, can move, if when mechanical hand length is not enough, can increases by a mechanical hand and merge use.

The present invention has the features such as simple in structure, esy to use, safe and reliable.
