A kind of portable stretcher type external chest compression reanimate device
Technical field
The present invention relates to a kind of portable stretcher type external chest compression reanimate device, belong to technical field of medical instruments.
Background technology
After the human body generation sudden cardiac arrest, need manual work be pressed into not a half hour by international practice, maybe be longer to some patient, Te Te is that the patient to coronary thrombosis is nowhere near.Push extremely effort because of manual work, especially on ambulance, because the working place is limited, it is not enough that medical personnel push duration, often occurs affecting adversely, abandons rescuing cardiopulmonary all standing patient's treatment.
Summary of the invention
The present invention is a kind of portable stretcher type external chest compression reanimate device, can cooperate stretcher to use, and the patient lies on the back and is positioned on the stretcher; By two rope bands main frame is lain in the front; Cooperate storage battery power supply, can realize constantly back and forth pushing automatically the patient chest, be specially adapted to the disaster field first aid.
Portable stretcher type external chest compression reanimate device comprises reducing motor, special shape gear, piston rod, spring, pressing plate, and reducing motor drives special shape gear and rotates, and said special shape gear upper outer circumference divides circumference to have teeth; On the said piston rod tooth bar is set, said tooth bar and teeth interlock, said piston rod lower end connects pressing plate, and the other end connects spring, and said piston rod promotes spring savings energy.
Advantage of the present invention:
(1) design of employing special shape gear and spring, " the fast pressure "---" putting slowly " combines, and sense of rhythm is strong; Having overcome other electromechanics pushes the full stroke uniform of reanimate device and pushes drawback; Approaching manual work more pushes process (explain: at anodontia half cycle, because piston rod loses the interlock of motor, spring is in abrupt release mechanical energy; Drive pressing plate and act on patient's chest, can realize " the fast pressure "; The half cycle of tooth is being arranged, can artificially regulate rotating speed of motor, recently realizing by changing the motor deceleration; As the patent protection content, piston rod does not move upward, and pressing plate leaves patient's chest; Compress the spring acting simultaneously; Deposit mechanical energy realizes pushing preparing for lower half, can realize " putting slowly ");
(2) pressure controlled (selecting the coefficient of elasticity of spring) is convenient to different patients' rescue;
(3) frame for movement is simple, portable convenience;
(4) liberation medical personnel both hands improve rescued effect;
(5) can implement machinery recovery with the shortest time to the cardiopulmonary patient that stops fighting in onset site, and the overall process that is maintained until in transit, is admitted to hospital and finishes up to rescuing, the required time of enough artificial resuscitation rescues is prolonged.

The specific embodiment
Below in conjunction with specific embodiment, the present invention is elaborated.
With reference to figure 1, Fig. 2 and Fig. 3, portable stretcher type external chest compression reanimate device comprises reducing motor 1, axle 2, special shape gear 3, piston rod 4, spring 5, pressing plate 6, after reducing motor 1 energized 11; Pass torque to special shape gear 3 through axle 2; Special shape gear 3 upper outer circumference divide circumference to have teeth, when special shape gear 3 turns clockwise, and the teeth interlock on the beginning of A point and the piston rod 4; Dragging piston moves upward; And the spring 5 at compression main frame top, until the B point, the spring compression finishes; Special shape gear 3 does not have teeth after the B point, loses interlock moment, reducing motor 1 zero load this moment, and piston rod 4 presses down rapidly under the effect of spring 5, drives the pressing plate 6 that is attached thereto and accomplishes an external chest compression process; At this moment, two rope band 14 1 ends lie on the rope band hook 7 of main frame both sides, and an end lies in stretcher 13 both sides, patient 10 relative fixed of lying on the back.Under the effect of motor, special shape gear and piston rod begin interlock next time then, go round and begin again, and both can realize constantly back and forth pushing automatically the patient chest.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
