Abstract

The utility model discloses a novel emergency stretcher, essentially consisting of a stretcher body (1), a stretcher board (2) and a four-bar linkage mechanism (3); wherein, the stretcher body (1) is formed by welding a vertical beam (11), a transverse beam (13) and stretcher legs (14), the front end and the back end of the stretcher body (1) are provided with the four-bar linkage mechanism (3) which is formed by hinging an overturning crank (31), a connecting bar (32), a frame connecting rod (33) and the transverse beam (13); the overturning crank (31) is turned by a rotating grip (12), the four-bar linkage mechanism (3) manipulates a stretcher board A (21) and a stretcher board B (22) which are fixedly connected with connecting bar (32) to realize the process of unlocking and butt joint, and wounded and diseased persons can be safely rescued by the butt joint process. The emergency stretcher has novel and simple structure, low production cost as well as simple usage, maintenance and repair.

Description

Novel first aid stretcher

Technical field

This utility model relates to a kind of medical rescue apparatus, especially a kind of novel first aid stretcher.

Background technology

Stretcher is the basic tool a kind of commonly used of the carrying sick and wounded in field first aid and the clinical treatment work.When existing stretcher is carried the enforcement sick and wounded, all to realize that the sick and wounded are from the transfer between the scene of the accident, emergency tender, sick bed, various examinating couch and the operating-table etc. basically by the lift to move sick and wounded.For after stupor, shock, spinal fracture, myocardial infarction, the operation and long-term bed etc. should not and the sick and wounded that move of inconvenience, not only can increase their pain and misery after moving, and exist some potential danger, cause that easily sick and wounded's state of an illness increases the weight of or produce pair to damage.Because how unordered in a jumble the people is, often cause that also various transfusions and drainage pipe people take off for pulling in the handling process, loosening etc.Design a kind of stretcher for this reason, guarantee that the sick and wounded's whole body posture in the carrying transfer process does not change, finish the process of immigration (going out) stretcher stably, injury and the harmful effect to them is very necessary in this process thereby reduce.

Summary of the invention

According to background technology, the purpose of this utility model is to avoid above-mentioned deficiency, providing a kind of is divided into two the stretcher plate, be separately fixed on the connecting rod of doing the Planar Compound motion in two four-bar mechanisms, rotation upset crank during work, the stretcher plate is turned to horizontal level and achieves a butt joint, in this process, make stretcher dock a side and remain the approximate straight line motion track, the stretcher plate just inserts the gap between its back and horizontal plane from both sides, sick and wounded back along horizontal line like this, with the sick and wounded and surface separation, last two plates close up butt joint, thereby the sick and wounded " are embraced " the stretcher from ground (perhaps other positions)! Realize the novel first aid stretcher of stretcher plate self-locking then by four-bar mechanism self character and auxiliary seat belt apparatus.

To achieve these goals, this utility model is achieved through the following technical solutions:

A kind of novel first aid stretcher, mainly by stretcher body (1), stretcher plate (2) and quadric chain (3) are formed, wherein: vertical beam (11), crossbeam (13) and stretcher lower limb (14) are by being welded to connect, and rotate grip (12), whole formation stretcher body (1) to what be provided with vertical beam (11) axial rotation relatively at the end axis of vertical beam (11); Stretcher plate (2), form by neutral straight plate face and dual-side curved surface, and it is identical structurally to be divided into shape from the centre, two stretcher plate A (21) and stretcher plate B (22) that size equates, and at stretcher plate A (21) and the last seat belt (23) of installing of stretcher plate B (22); Go up by rotating pin (34) hinged at crossbeam (13) with an end of upset crank (31) and side link (33), the other end of upset crank (31) and an end of connecting rod (32) are hinged, the other end of side link (33) and connecting rod (32) are hinged on the appropriate location of shaft, fixedly connected with stretcher plate (2) in lower end at connecting rod (32), upset crank (31) is affixed with rotation grip (12), common formation quadric chain (3), the link position parameter of its quadric chain (3) should guarantee the correct butt joint of navigability and stretcher plate A (21) and stretcher plate B (22), about 40 ° of α angle maximum, stretcher plate A (21) and stretcher plate B (22) opposite flank opening time are apart from the about 1.08m of H-number.

Owing to adopt technique scheme, the utlity model has following advantage and effect:

1, this utility model has been removed some potential dangers of inconvenience, pain and existence that the sick and wounded suffer at the scene in first aid and the clinical treatment work basically to greatest extent in all kinds of carryings, has embodied the design concept that people-oriented.

2, this utility model novel structure is simple, and manoeuvrable is easy to use, and is cheap, and working service and repairing are simple and easy.

The specific embodiment

By Fig. 1, Fig. 2 and Fig. 3 a kind of novel first aid stretcher is shown, mainly by stretcher body 1, stretcher plate 2 and quadric chain 3 are formed, wherein: vertical beam 11, crossbeam 13 and stretcher lower limb 14 are by being welded to connect, and rotate grip 12, whole formation stretcher body 1 to what be provided with vertical beam 11 axial rotation relatively at the end axis of vertical beam 11; Stretcher plate 2 be made up of neutral straight plate face and dual-side curved surface, and it is identical structurally to be divided into shape from the centre, two stretcher plate A21 that size equates and stretcher plate B22, and seat belt 23 is installed on stretcher plate A21 and stretcher plate B22; Hinged with an end of upset crank 31 and side link 33 at crossbeam 13 by rotating pin 34, the other end of upset crank 31 and an end of connecting rod 32 are hinged, the other end of side link 33 and connecting rod 32 are hinged on the appropriate location of shaft, fixedly connected with stretcher plate 2 in lower end at connecting rod 32, upset crank 31 is affixed with rotation grip 12, common formation quadric chain 3, the link position parameter of its quadric chain 3 should guarantee the correct butt joint of navigability and stretcher plate A21 and stretcher plate B22, about 40 ° of α angle maximum, stretcher plate A21 and stretcher plate B22 opposite flank opening time are apart from the about 1.08m of H-number.

Other knows, rotates the promptly rotatable upset crank 31 fixed with it of grip 12 by manual rotation, by upset crank 31 drivening rods 32 and side link 33, i.e. butt joint and the unlatching of may command stretcher plate A21 and stretcher plate B22.

In the motor process of butt joint, satisfy its relative lateral edges and in motor process, remain the approximate straight line motion track, guaranteed that stretcher plate 2 can insert the gap between its back and horizontal plane smoothly from both sides, sick and wounded back along the horizontal line direction, the sick and wounded from ground (perhaps other positions) are embraced the stretcher; The sick and wounded move into that its whole body posture does not change in (going out) stretcher process, move, thereby reduce in this process injury and other harmful effects to them.
