Abstract

The invention relates to a medical appliance, in particular to a voice prompt manual cardiopulmonary resuscitator used in first aid and rescue of cardiac arrest cases. The major technology adopts manual operation that: a user can hold a handle by hand to press down an adjustable pressing rod at a frequency of 100times/minute; thus, a pressing column is driven to move up and down 4 to 5cm, and a pressing rubber head presses the lower part of a breastbone to move up and down 4 to 5cm in the same way, thereby reaching the goal of cardiac compression; moreover, when moving up and down, the pressing column pulls an air-compressing rack and an air sac cover to move downwards periodically at a frequency of 10times/minute; and a ventilation change-over switch at the upper end of the air-compressing rack can be adjusted to ensure that 300 or 600ml air in an air sac enters the respiratory tract of a patient through a chassis air sac blow vent, an air division check valve, and the like; thus, an inspiratory process of the patient is completed. The voice prompt manual cardiopulmonary resuscitator has the advantages of simple structure, easy manufacturing, low price and no restriction on using condition.

Description

Voice prompt manual cardiopulmonary resuscitator

Technical field

The present invention relates to a kind of medical apparatus and instruments, more particularly, it is that voice prompt manual cardiopulmonary resuscitator is rescued in a kind of first aid that is used for the cardiac arrest case.

Background technology

At present, China overwhelming majority medical institutions, basic unit's middle and small hospital particularly, most with free-hand cardiopulmonary resuscitation rescue cardiac arrest case, before free-hand cardiopulmonary resuscitation almost is cardiac arrest institute, the unique method of first aid outside the institute, but free-hand cardio-pulmonary resuscitation is because the difficult control of rhythm and frequency, factors such as amplitude and number of times are hard to keep cause salvage success rate not high, during particularly single implementation and operation, because cardiac compression is forced to interrupt often, factors such as operator's fatiguability cause salvage success rate lower, cross infection between the doctors and patients takes place simultaneously easily, the case that minority hospital uses cardio-pulmonary resuscitation machine to rescue cardiac arrest, but existing cardio-pulmonary resuscitation machine miscellaneous, all depend on electricity (electronic), gas power sources such as (pneumatic), can only be limited in the institute and use, and have use inconvenience, complicated operation, problem such as cost an arm and a leg has obviously restricted popularizing of cardio-pulmonary resuscitation machine.At present, still finding no voice prompt manual cardiopulmonary resuscitator on medical apparatus and instruments market sells.

Summary of the invention

The objective of the invention is to overcome in the prior art not enough, provide a kind of simple in structure, be easy to processing and manufacturing, manual operation, simple and fast, be not subjected to condition restriction, cheap a kind of voice prompt manual cardiopulmonary resuscitator.

The present invention can obviously improve before the hospital, institute and the salvage success rate of heart beating all standing case outside the institute, and avoided the cross infection between the doctors and patients, alleviated operators' such as medical worker labor intensity, simultaneously because this machine adopts voice suggestion, institute even can be generalized to high-risk place and family so that in medical institutions, particularly middle and small hospital, community medical service center popularize, reduce national sudden death rate, prolong whole people's average life span.

Purpose of the present invention is achieved by following technical proposals:

The present invention adopts manually, handle is fixed on two scalable pressing levers, in the parallel insertion adapter of this pressing lever, the front end of this adapter is connected with pivot bolt on the casing, the rear end is connected with upper end by compression leg, the lower end that should press compression leg connects by the moulding head, should make tooth bar by the middle part of compression leg, the outer tooth ring interlock of this rack and pinion mechanism, the internal gear of this gear mechanism is fixed on the power transmission shaft, the fixedly connected imperfect eccentric gear of this power transmission shaft, the different parts of this imperfect eccentric gear and the rotating tooth bar interlock of calming the anger, this tooth bar of calming the anger is connected with airbag cover, this airbag cover is pressed on the air bag, have back-moving spring to be fixed on the chassis in this air bag, this chassis is connected on the underframe by two pairs of chassis pull bars, and the part of every pair of chassis pull bar is made into pull bar tooth bar while and synchromesh gear interlock.Underframe is connected with the column plug-in type of base, Spring Card by underframe is connected with the locked groove card-locked type of column, two parts of this base connect by the slide bar plug-in type, air bag is connected by managing in breather and the chassis, should connect air filtration check-valves and air back valve by interior pipe, this air back valve connects steam hose, and this hose connection gas divides flow check valve, this minute, flow check valve was connected with exhalation vents with face shield, and was hung on the hook at headrest two ends.Voice module is installed in the headrest and connects speaker, starting switch.The calm the anger upper end of tooth bar connects the ventilation change-over switch ventilation is selected between 300 or 600 milliliters.

Owing to take its beneficial effect of above-mentioned side's technical scheme voice prompt manual cardiopulmonary resuscitator provided by the invention to be: (1) is compared with free-hand cardio-pulmonary resuscitation, and cardiac compression of the present invention is finished indirectly by the scalable pressing lever, and leverage makes the operator laborsaving a lot; (2) according to patient and operator's different situations, the adjustable pressing lever of push-and-pull, the size of exerting oneself when promptly scalable is pushed is operated light indefatigability; (3) this machine has been avoided because the compression number that operator's fatigue causes and the decay of amplitude guarantee resuscitation effect by beat sound and seven color scale indication compression frequency and amplitudes; (4) this machine is by the air bag air feed, and frequency, the quality and quantity of lung ventilation are more scientific and reasonable, meet up-to-date international standard, effectively improve salvage success rate; (5) this machine has cuboid voice suggestion headrest, can select different height pads in patient's neck, makes different bodily form patients' air flue all more unobstructed, and the rhythm and pace of moving things and points for attention are installed, pushed to the machine of voice suggestion simultaneously; (6) stopped the operator and contacted, effectively avoided cross infection with the direct of disease population, nose; (7) compare with existing various cardio-pulmonary resuscitation machines, the gentle power source that waits of not electricity consumption is not subject to the objective condition restriction so use, and volume is little, in light weight in addition, rescues so both can be used for hospital, also can be used for institute before, institute outside, on the way in first aid, of many uses; (8) base and sole adopt can expand, inserted mode, be applicable to the patient of the various bodily forms; (9) base and sole etc. also adopt inserting mode, assemble very conveniently rapidly only to use the 10-15 time of second from being installed to use, do not waste each second of first aid and rescue; (10) the very simple and outfit sound prompt function of in-local, not only the medical worker can use, and the general population all can use in simple training or after reading description, is beneficial to especially and popularizes high-risk place, family etc.; (11) production cost is lower, and the market price should be starkly lower than other cardio-pulmonary resuscitation machines, obtains small medical mechanism and individual's recognition and acceptance easily, and the future market has a extensive future.
