Abstract

The invention provides a control circuit of device used in rescuing asphyxia people belonging to the electronic technical field, which solves the problems of the prior cardio-pulmonary resuscitation machine such as single function, complex operation and fixed frequency of massage and oxygen therapy. The control circuit of cardio-pulmonary resuscitation machine comprises a control center, wherein the control center is connected with an electrical source module supplying electricity for the control center and a display used for displaying work information; a display drive chip is arranged between the display and the control center; the control center is connected with a massage controller and a respiratory controller; massage frequency of the massage controller, ventilation frequency of the respiratory controller and quantity of sub-oxygen therapy are controlled by the control center; moreover, the control center is also connected with an adjusting device used to adjust massage frequency, massage ventilation frequency and quantity of sub-oxygen therapy. With complete functions, simple operation and reasonable design, the invention can select appropriate ratio of massage frequency and ventilation frequency in time according to resuscitation state of patient, thereby possessing high success rate of rescue.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a control circuit of a device for rescuing asphyxiated persons. Background technique [0002] In the emergency rescue of suffocation caused by drowning, electric shock, gas poisoning, etc., the traditional method is manual chest compression and artificial respiration. Manual resuscitation has its limitations, and the resuscitation technique of rescuers directly determines the effect of resuscitation; at the same time, people who perform manual resuscitation are more prone to fatigue, and at the same time, they cannot increase the frequency of external chest compressions to ≥100 times per minute. One-person operation often causes rib fractures and visceral injuries due to excessive physical exertion, improper pressing force and inaccurate position; frequent replacement of performing personnel will lead to interrupted pressing, affect the effect of resuscitation, and reduce the s...
