Detailed description of the invention

Fig. 1 is the structural schematic diagram of the embodiment of the present invention.

Specific embodiment

Present invention is further described in detail with specific embodiment with reference to the accompanying drawing: as shown in Figure 1, mark is such as Under: lifting support A, bottom vertical part a1, horizontal part a2, high vertical part a3, edge of bed fixed frame B, motor 1, spoke shaft 2, spoke 3, iron cable 4, horizontal axis 5, spring 6, briquetting 7, pressing sleeve 8, pilot sleeve 9, edge of bed fixing clamp 10, pulley horizon bar 11, pulley are fixed Bar 12, bolt handle 13, variable force pulley 14, conflict block 1, light emitting diode 16, conflict block 2 17, lower bracket 18, upper bracket 19, strip grooves 20, radius adjustment hole 21, top connection 22, lower contact 23, height adjusting holes 24, motor cabinet 25, driving gear 26, Driven gear 27, bearing 28, revolving speed counter 29, spoke cooperate with bar 30.

A kind of light heart compressions instrument includes the spoke shaft 2 that the motor 1 of bottom surface is arranged in and is driven by it, spoke shaft Both ends be each provided with a spoke 3, a lifting support A is each provided with above two spokes in left and right and is connected with iron cable 4 It connects, lifting support includes bottom vertical part a1, horizontal part a2 and high vertical part a3, the inside bending of horizontal part, two lifting supports pair in left and right Claim setting, horizontal axis 5, the intermediate lower section setting spring 6 of horizontal axis and the pressing for heart compressions are provided between two high vertical parts Block 7, the periphery of briquetting is provided with pressing sleeve 8 and the two can be relatively movable, and spring is set in the periphery of briquetting, spring Upper end against horizontal axis, the outer casing top surface of the lower end of spring against pressing sleeve；This is a simplest scheme, lifting branch Frame is made into integration, and no height adjustment and left and right adjusting function, lifting support are pulled downward on by iron cable, so that briquetting pressing disease The chest of people, instead of manually pressing；But because iron cable is flexible connection, on spoke rotation another side, iron cable can not provide lift The active force of lifting support is risen, lifting support is lifted as power to pressing sleeve and the counter of spring by human chest at this time, from And realize reciprocating operation.

Preferably, lifting support is divided into lower bracket 18 and upper bracket 19, two brackets are docked in horizontal part, are led at docking It crosses strip grooves 20 to fix with bolt, so that the position of briquetting can move left and right, the cardiac position of patient can be displaced to, Lower bracket and the preferred stainless steel of upper bracket or aluminium alloy square bar, it is vertically arranged.Further, there are six radius tune for setting on spoke Knothole 21, the both ends of iron cable are respectively arranged with top connection 22 and lower contact 23, and jack is provided in lower contact, and lower contact passes through tune Knothole fixator 31 is inserted in one of radius adjustment hole；The bottom end of top connection and bottom vertical part passes through height adjusting holes 24 and spiral shell Bolt docking, there are six height adjusting holes, and radius adjustment hole is consistent with the spacing of height adjusting holes, top connection and/or bottom vertical part Bottom end is arranged in pilot sleeve；Two positions, which are provided to realize, is adjusted and is pressed amplitude tune by the starting altitude of die block Section enables briquetting to carry out pressing work with suitable height and dynamics, also spring can be made to obtain enough screen resiliences.

One is disclosed in patent database with cluster patent CN104546427A outer pressing device for critically ill patients, uses battery Elastic balloon and pressing plate is driven to carry out heart compressions, in the course of work, the stress of the rib cage of human body and rebound are same positions It sets, rib cage is be easy to cause to be broken, especially for child old man or the adult of constitution difference, because heart compressions need strength very Greatly, each pressing of adult, heart exterior feature will sink 3-4CM or so.

And in the application, when pushing, sleeve was pressed before this and contradicts thorax then briquetting downlink again, that is to say, that originally The active force born by the thorax of briquetting, some is pressed the thorax at sleeve and shares, and area, which increases, adds two It is secondary to put forth effort, it can preferably protect rib cage and its perienchyma；When rebound, and pressing sleeve and briquetting are jacked up simultaneously.

Iron cable belongs to flexible connection, and when spoke goes to another side, lower pressure can suddenly disappear, and patient's thorax only needs to push up Lifting bracket, the weight for pressing sleeve and briquetting；And in patent CN104546427A outer pressing device for critically ill patients, bullet The frequency of property air bag can only theoretically accomplish it is consistent with the thorax fluctuating frequency of patient, in fact, can be in the lower limit pole of thorax An active force to liquidate is generated on point or uplink pole with pressing plate, this point injures rib cage larger.

The inner surface of pressing sleeve is provided with conflict block 1, and the outer surface for pressing sleeve is provided with light emitting diode 16, The outer surface of briquetting is provided with conflict block 2 17, and when conflict block two contacts conflict block for the moment, circuit is connected, light emitting diode hair In place whether light press each time for being promoted.

The bottom surface of motor is provided with motor cabinet 25, and motor selects low speed adjustable motor, is provided with master on the output shaft of motor Moving gear 26 is provided with driven gear 27 on spoke shaft, and driving gear is engaged with driven gear, and the end of the output shaft of motor is set It is equipped with bearing 28 and revolving speed counter 29, bearing is fixed on motor cabinet；Revolving speed counter 29 is for recording the number such as time, number According to.

Edge of bed fixed frame B is provided with outside the bottom section of bottom vertical part, edge of bed fixed frame has included guidance lifting direction and can prevent The only pilot sleeve 9 of lifting support lodging and the edge of bed fixing clamp 10 for clamping patient bed edge, pilot sleeve is vertically arranged, bed It is put along fixing clamp horizontal direction, opening is arranged inwardly；Edge of bed fixed frame further includes pulley horizon bar 11 and two pulley fixed links 12, pilot sleeve runs through edge of bed fixing clamp, and edge of bed fixing clamp is laterally put, and the bottom surface of edge of bed fixing clamp is arranged in pulley horizon bar And it is longitudinal put, the bottom surface of pulley horizon bar and angularly disposed is arranged in pulley fixed link；Edge of bed is fixed to accompany upper layer and lower layer folder Piece and it is provided with bolt handle 13.

The bottom end of pulley fixed link is provided with variable force pulley 14, and two variable force pulleys clamp iron cable, because when spoke rotates, The movement of iron cable can convert aspect, and power can be conducted to lifting support, bring it about and rock；Pilot sleeve, edge of bed fixing clamp, Pulley horizon bar and pulley fixed link are welding integral, the preferred stainless steel of material.

A spoke collaboration bar 30 is provided between two pulley horizon bars, spoke cooperates with bar to run through pulley horizon bar, prevents Height on both sides are inconsistent when rocking or run when only lifting support works.
