Abstract

The utility model discloses an external cardiac pressing device for medical treatment, particularly an external cardiac device for prompting the cardiac resuscitation. The utility model is composed of a bottom plate for fixing a patient, a bracket arranged on the bottom plate and a pressing device arranged on the bracket, wherein the pressing device is provided from top to bottom with a motor, an upper compass which is fixed on a rotary shaft of the motor and is provided with a roller, and a lower compass which is provided with a circular ring-shaped track having different depths; the lower end surface of the lower compass is provided with a pressing head; the motor rotates to drive the upper compass to rotate; the roller on the upper compass rolls in the track of the lower compass to realize the up and down movement of the pressing head, and accordingly, the purpose of pressing the chest is achieved. The utility model has the advantages of simple structure and convenient operation.

Description

The closed cardiac massage squeezer

Technical field

This utility model relates to a kind of medical instrument, and especially breast impels the medical apparatus and instruments of cardiac resuccitation outward.

Background technology

Traditional CCCR, the method that mostly adopts operator's both hands to push rhythmically at patient's chest realizes.Require when pushing: push the degree of depth 3-4cm that sink, compression frequency is 80 times/minute, thereby manipulation strength is bigger.In practical operation, often stretch not directly because of operator's arm, it is firmly uneven to form palm; Or excessive because of operator's physical demands, need continually many reasons such as exchange operators, the effect that influence is pushed particularly is prone to complication such as fracture of rib.

Summary of the invention

The purpose of this utility model is, a kind of closed cardiac massage squeezer is provided, and it can alleviate operator's manipulation strength effectively, strengthens to push effect, simultaneously, can avoid tradition to push because of the firmly generation of the uneven complication such as fracture of rib that cause.

The purpose of this utility model is achieved through the following technical solutions: a kind of closed cardiac massage squeezer, it is characterized in that it comprises that support, support below connect base plate, support top is pressurizing unit, the flexible extrusion head that pressurizing unit connects by power-driven mechanism with driving mechanism is formed, power-driven mechanism comprises housing, device is loaded on the last compass on the motor output shaft at the intravital motor of shell, following compass, the extrusion head that is positioned at compass below be contained in down compass below; Following compass has the annular groove track on the upper surface, and the degree of depth of track not equal-height position and low ebb is symmetry shape; The roller that symmetrically arranged two orbital motions are arranged on the last compass lower surface is flexible connection with housing around the following compass.

The utility model has the advantages that: simple in structure, small and exquisite, conveniently moving, fixing invalid base plate and pressurizing unit are in aggregates, and squeezing effect is good.

The specific embodiment

As shown in Figure 1, base plate (4) is used for fixing patient, and two ends are bent upwards, in the middle of it for plug-in type to adjust its width according to patient, support (3) and auxiliary stand (5) are housed, support (3) adjustable height at the two ends of base plate.Pressurizing unit is contained on the support (3).Motor (6) is arranged in housing (1), on motor (6) axle, compass (7) is housed, the useful pillar in last compass (7) lower surface (12) is contained in the roller (10) on compass (7) lower surface, compass (8) under again being, the lower surface dress extrusion head (2) of following compass (8), there is annular groove track (9) upper surface, and the degree of depth of track (9) does not wait, and high lower is symmetry shape.Descend in the present embodiment compass (8) to be fixed on the housing (1) with some symmetrically arranged springs (9).Motor (6) adopts stepless speed-regulating motor.

Its work process is: patient lain on the back on base plate (4), adjusts baseplate width and support (3) highly, and auxiliary stand in the support (5), energized promptly begins extruding.When roller (10) moves to the low ebb of track (9), following compass (8) does not bear pressure and extrusion head (2) is pulled on the answer normal condition by spring (9), compressing compass (8) down when roller (10) moves to track (9) high-order, moving downward minimum point together with extrusion head pushes patient's chest, so repeatedly, motor whenever turns around and once pushes, and the extruding frequency is adjusted by buncher (6).

Claims

1, a kind of closed cardiac massage squeezer, it is characterized in that it comprises that support (3), support (3) below connect base plate (4), support top is pressurizing unit, the flexible extrusion head that pressurizing unit connects by power-driven mechanism with driving mechanism is formed, power-driven mechanism comprises housing (1), the motor (6) of device in housing (1) is loaded on the last compass (7) on the motor output shaft, is positioned at the following compass (8) of compass (7) below, the lower surface that extrusion head (2) is contained in down compass (8); Following compass (8) has annular groove track (9) on the upper surface, and the degree of depth of track (9) not equal-height position and low ebb is symmetry shape; Symmetrically arranged two rollers (10) along track (9) motion are arranged on last compass (7) lower surface, be flexible connection with housing (1) around the following compass (8).

2, a kind of closed cardiac massage squeezer according to claim 1 is characterized in that compass (8) is articulated on the housing (1) with some symmetrically arranged springs (11).

3, a kind of closed cardiac massage squeezer according to claim 1 is characterized in that the base plate two ends upsweep, and intermediate width is adjustable.

4, a kind of closed cardiac massage squeezer according to claim 1 is characterized in that at the other end of base plate auxiliary stand (5) being arranged.
