Abstract
The utility model relates to an execution device for replacing the artificial extracorporeal heart compression, which belongs to the field of medical devices and is used for rescuing patients with cardiac arrest. The execution device has the following characteristics: (1) the volume is small: the overall dimension of a whole resuscitation machine is that length*width*height is equal to 600*500*150mm; (2) the structure is reliable, and the reliable chest compression performance is realized through a mechanical transfer device; (3) the use is convenient and fast, when the execution device is used for rescuing the patient, the rescue can be carried out by switching on as long as the patient is fixed by a compression belt; and (4) energy conservation: power of the machine is provided by a direct current battery, and the charging can be carried out at any time. The device is driven by adopting a direct current motor, speed reduction is carried out through a two-stage open gear speed reducer, and the device is connected with a gear eccentric wheel connecting rod mechanism through a coupling, thereby transforming the continuous rotation to the reciprocating swing, further transforming the reciprocating swing to the reciprocating rotation of a gear through a gear-rack mechanism, directly connecting the compression belt on a gear shaft, doing the relaxing-tensing actions under the drive of the whole mechanism and further achieving the purpose of chest compression of the patient. The mechanism can realize the adjustment of compression frequency, depth and pressure and simultaneously solve the problems of lock relaxing and resetting. Compared with the prior art, the execution device has the advantages of simple structure, convenient use, easy maintenance and carrying and low cost, thereby being very suitable for the field cardiopulmonary resuscitation needs outside hospitals and during the wartime.
Description
Affiliated technical field
This utility model relates to a kind of actuating unit that substitutes artificial external cardiac compression, belongs to medical instruments field, is used to rescue the sudden cardiac arrest patient.
Background technology
To the sudden cardiac arrest patient, adopt and manually push following 1/3rd intersections in the breastbone at present.By hand cardio-pulmonary resuscitation Chang Yin push the position inaccurate, firmly method not to, according to pressing depth be difficult to grasp, compression frequency is irregular, push and loosen time ratio and forbidden, push and attend to one thing and lose sight of another with breathing and influence resuscitation effect.Repeatedly substituting needs repeatedly location, loses time, and the recovery success rate is low.The purpose of this utility model exploitation is to design and develop out a kind of portable belt cardio-pulmonary resuscitation machine at lower cost, with satisfy outside the institute, the demand of on-the-spot cardio-pulmonary resuscitation in wartime, cardio-pulmonary resuscitation machine at various pneumatic principles and theory of mechanics on the present market is bulky, difficult in maintenance, not portable, characteristics such as cost an arm and a leg design a kind of being easy to carry, novel cardio-pulmonary resuscitation machine easy to use, that cost is little.
Summary of the invention
The purpose of this utility model provides a kind of outer chest heart pressing device, make cardiac compression more laborsaving, save time, push effectively, safety the success rate height.
Characteristics of the present utility model are: one, volume is little: whole resuscitating machine overall dimension, length * wide * height=600 * 500 * 150mm.Two, reliable in structure realizes chest compression function, dependable performance by mechanical driving device.Three, convenient to use.When giving emergency treatment to a patient, only patient need be used by pressure zone and fix, energising can be rescued.Four, energy-conservation: the power of machine is provided by dc-battery, needs little energy, also can charge at any time.The technical scheme that its technical problem that solves this utility model adopts is: device adopts dc motor to drive, slow down through a secondary exposed gear decelerator, connect the gear eccentric wheel connecting rod mechanism by shaft coupling, to rotate continuously and be converted into reciprocally swinging, again by rack-and-pinion, reciprocally swinging is converted into the reciprocal rotation of gear, directly be connected on the gear shaft by pressure zone, under the driving of entire mechanism, do and unclamp the tensioning action, thereby reach the purpose of pushing the patient thoracic cavity.
This utility model compared with prior art has following advantage: simple in structure, easy to use, be easy to safeguard carry, cost is low, is fit to very much outside the institute, the demand of on-the-spot cardio-pulmonary resuscitation in wartime.
Description of drawings
Fig. 1 is this utility model schematic three dimensional views
Fig. 2 is this utility model transmission diagram.
Fig. 3 is this utility model schematic top plan view.
Fig. 4 is the local intention of this utility model.
Among the figure: 1 motor, 2 yielding couplings, 3-8 are secondary helical gear reducer (shaft coupling, high speed shaft, high speed shaft gear, jackshaft, slow-speed shaft, slow-speed shaft gear), 9,11 eccentric gear mesh, 10 motors, 12 connecting rods, 13 slide blocks, 14 press the pressure zone installation shaft, 15 rack-and-pinion.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further: this utility model adopts 24V dc motor 1 to drive, and motor is battery-powered, also can power through adapter; Yielding coupling 2 connects motor and a secondary open type helical gear reducer (3-8) slows down, transmit motion on the gear eccentric 9-11 through shaft coupling again, the connecting rod 12 of eccentric guide-bar mechanism is done reciprocally swinging, the linear reciprocation that is converted into tooth bar 15 moves, warp and gears engaged, be converted into reciprocal rotation, directly be fastened on the gear shaft 14 by pressure zone, the reciprocal rotation of the angle that under the driving of entire mechanism, fixes, make to do and unclamp tensioning action, thereby reach the purpose of pushing the patient thoracic cavity by pressure zone.About three adjustable realizations: chest compression frequency 100 times/minute, adjustable; Chest compression degree of depth 2-5cm, adjustable; Press pressure: the 20-50 kilogram, adjustable.
Wherein compression frequency is realized by the mode of speed regulation of direct current generator, change armature voltage U and reduce the armature voltage speed governing, but armature circuit must have the dc source of adjust blood pressure, armature circuit and energized circuit resistance are as far as possible little, the voltage drop slow-speed of revolution descends, artificial characteristics's hardness is constant, running speed stable, but stepless speed regulation; According to pressing depth with pressure by lie in the patient on one's body with the position realize.
Loosen realization with reset issues about locking
Consideration is realized eccentric wheel connecting rod mechanism by geared linkage mechanism, so that at the eccentric place one motor is installed.Motor cooperates block to realize reset issues.When locking took place, main motor quit work, and is discharged by motor.
