Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of electropneumatic device for resuscitating heart and pulmones.
Background technology
(the sanguimotor maintenance of CPR (cardiopulmonary resuscitation) process is by chest by current CPR
Outer the fundamentals such as to press, loosen, just ventilating and form, either side can influence the production of CPR processes forward blood flow (Reperfu- sion)
It is raw.The kinetic energy of first-aid personnel's external chest compression is converted into the increase of chest pressure during CPR, in the assistance of cardiovascular valve structure
Lower generation forward blood flow.The efficiency that external chest compression generates forward blood flow is held by the frequency, strength and external chest compression of external chest compression
The continuous time accounts for entire pressing --- and the ratio of relaxation time is determined.The generation of CPR process forward blood flows is by intrathoracic pressure power
What changes with time was realized, external chest compression causes artery and vein vascular system pressure consistency in thoracic cavity to increase.Pressing force is to influence blood flow
The principal element of generation.Then intrathoracic pressure is higher for pressing force increase, and forward blood flow is consequently increased；But Overexertion presses
It can lead to wound and thoracic cavity profile deforms and excessively high intrathoracic pressure, so as to have a negative impact to Clinical Outcome.
In practical pressing, Manual press depth of the medical worker in CPR is often inadequate, is primarily due to wish to keep away
Exempt to damage breastbone, the wall of the chest and intrathoracic internal organs, while also have and artificially press insufficient propensity, if excessively shallow, be not achieved
The purpose in thoracic cavity is squeezed, if the too deep internal organ that can injure patient or causing patient's fracture of sternum.The frequency of chest compression is 110
Beat/min, which can make output quantity reach maximum in the range of rescue personnel's physical efficiency is born, but actual conditions are first aid people
Member tends not to reach this index, because external chest compression is big to the physical fitness requirement of first-aid personnel, and when needing longer pressing
Between.Low-frequency pressing, which ultimately causes patient's brain, still can not obtain enough blood supplies.
Pressing is the part in CPR, and the rebound of the wall of the chest can be such that intrathoracic pressure reduces so as to increase venous return volume, this
Blood volume (being generated by the inertia formed during pressing) than passively flowing back to heart is much greater.Effectively pressing and chest is complete
It is complete to loosen for generating forward blood flow, ensureing that important organ perfusion has the synergistic effect being mutually improved, it will be during recovery be made
Cardiac output maximizes.But desired success in salvage only is extremely difficult to by manually pressing, loosening, and to the rescue of rescue personnel
Technical ability and rescue skill requirement are higher, and easily generation rescue is ineffective, delays the problem of relief opportunity, even causes doctors and patients' lance
Shield.
