Description

The special-purpose respirator of emergency resuscitation

Technical field

This utility model relates to medical instruments field, is specifically related to the special-purpose respirator of a kind of emergency resuscitation.

Background technology

Patient's sudden cardiac arrest can occur in any time and (in the hospital or outside the hospital) Anywhere, be to implement cardio-pulmonary resuscitation (CPR) for one of the most effective rescue means of such patient, and in cardio-pulmonary resuscitation, providing rule for patient, quick and enough breathing supports (respiratory resuscitation) have medical status of equal importance with external chest compression (cardiac resuccitation).The recovery of tradition artificial heart-lung or machinery (electronic) Heart-lung restoring instrument all can only be absorbed in external chest compression (cardiac resuccitation), and effective breathing support of the special-purpose respirator of shortage recovery, thereby cause the following state of present cardio-pulmonary resuscitation: 1, as when the artificial heart-lung recovery, for reasonable rule is provided, effectively breathe and support, need the special medical care personnel of outfit or when cardio-pulmonary resuscitation, supported as the artificial respiration by the first-aid personnel of professional training.Can cause professional health care personnel waste like this, and under current condition, originally Zhuan Ye first aid medical personnel have been awkward just, and medical care personnel really need be provided at many first aids scene the support that practices artificial respiration, really made the matter worse.The both sides medical personnel that manually press and breathe support during 2, owing to cardio-pulmonary resuscitation need to keep in operation rule and rhythm, so may occur tacit disappearance mutually between the medical worker, cause and press and breathe antagonism.3, as using the motor machine Heart-lung restoring instrument to carry out external chest compression, the support that practices artificial respiration simultaneously also can produce and press and the stationary problem of breathing, and causes operational conflict, and this is disadvantageous for effectively suing and labouring of patient.Even 4 are rescuing the scene, has respirator commonly used, or even the respirator of very high-end costliness arranged, also because the people is asynchronous with such respirator, or electronic recovery instrument is asynchronous with respirator cooperates, and causes having respirator not use at last, because the required breathing support function of such respirator function and recovery patient is different fully, therefore under a lot of rescue states (respirator is arranged), still can only give the difficult situation that patient respiration is supported by the people.5, because modern first aid requirement is high, can be from tens minutes to several hours to whole rescue process, so tediously long rescue process can make the medical worker who provides breathing to support drained, even reduces rescue effect.

The utility model content

The technical problems to be solved in the utility model provide a kind of easy to use laborsaving, need not patent rescue knowledge, breathing gas supply with stablize high-quality, implement rescue effective, can not cause and press and breathe antagonism, breathe the emergency resuscitation special use respirator of good, applied range synchronously.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

The special-purpose respirator of a kind of emergency resuscitation, comprise housing and the pneumatic logic working cell and the control unit that are fixed on the housing, described housing is provided with display screen, key-press module and indicating lamp module, described pneumatic logic working cell comprises the air inlet air relief valve that is communicated with successively, pneumatic filter, gas allocation proportion valve, the pressure reduction vapour lock, gas delivery port, described control unit comprises continuous pressure transducer and controller, described display screen, key-press module, indicating lamp module links to each other with controller respectively, described pressure transducer is gathered gas allocation proportion valve respectively, the pressure reduction vapour lock, the air pressure of gas delivery port is also exported to controller, and described controller shows the duty of exporting and controlling gas allocation proportion valve according to the air pressure of input with the air pressure of input to display screen.

As further improvement in the technical proposal:

Described housing is rectangle plastics housings, and described air inlet air relief valve is fixed in the left side of housing, and described gas delivery port is fixed in the right side of housing.

The utlity model has following advantage: this utility model comprises housing and the pneumatic logic working cell and the control unit that are fixed on the housing, housing is provided with display screen, key-press module and indicating lamp module, the pneumatic logic working cell comprises the air inlet air relief valve that is communicated with successively, pneumatic filter, gas allocation proportion valve, the pressure reduction vapour lock, gas delivery port, control unit comprises continuous pressure transducer and controller, therefore can respiration parameter be set by key-press module, controller is according to the duty of the air pressure signal control gas allocation proportion valve of the respiration parameter that arranges and input, can realize the supply of more scientific and reasonable breathing gas on the one hand, and the knowledge that the enforcement rescuer does not need to give first aid to fully also can realize, can not cause and press and breathe antagonism, and press with breathe good synchronously, breathing quality height, highly beneficial to suing and labouring, the rescuer can also be saved from press on the other hand, can implement other rescue related measure, greatly improved the emergency resuscitation effect, the cardio-pulmonary function support that cooperatively interacts when improving cardio-pulmonary resuscitation, reduce the personnel selection cost, have easy to use laborsaving, need not patent rescue knowledge, the breathing gas supply is stablized high-quality, it is effective to implement rescue, can not cause and press and breathe antagonism, breathe good advantage synchronously, and it is little to the utlity model has volume, in light weight, easy to operate, portability, advantage such as removable, can be in hospital, outside the hospital, on the stretcher, use on the ambulance, also can be in the mine, the field, army, battlefield, use on the sea-going ships, can in the emergency medical equipment, have critical role.
