External chest compression auxiliary device

Abstract

The invention relates to an external chest compression auxiliary device which comprises an external chest compression auxiliary pad, limiting auxiliary supporting structures and an adaptive base supporting structure. The two sides of the external chest compression auxiliary pad are each detachably connected with one set of limiting auxiliary supporting structures, and an auxiliary plate capable ofmoving up and down is arranged on each limiting auxiliary supporting structure; the two sides of the external chest compression auxiliary pad are connected with the auxiliary plates, the limiting auxiliary supporting structures are provided with limiting assemblies for limiting the up-down movement range of the auxiliary plates and detection assemblies for detecting the up-down movement frequencyof the auxiliary plates, the limiting auxiliary supporting structures are detachably installed on the adaptive base supporting structure, and the adaptive base supporting structure is used for adjusting the mounting height of the limiting auxiliary supporting structures; and the external chest compression auxiliary device further comprises an interaction assembly for intelligent interaction, andthe detection assemblies are connected to the interaction assembly. Compared with the prior art, the device can be rapidly deployed, auxiliary support of the pressing frequency and the pressing depthcan be provided, and the effectiveness of external chest compression is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a chest compression auxiliary device. Background technique [0002] According to statistics, there are at least 135 million deaths due to cardiovascular diseases in the world every year, and 1.8 million deaths due to cardiac arrest in my country each year, accounting for 6% of the overall mortality rate. However, if patients with sudden cardiac arrest can be effectively rescued within 6 minutes, irreversible damage to brain cells can be avoided, and the success rate of rescue within 1 minute is as high as 90%. Nevertheless, due to the low rate of cardiopulmonary resuscitation (CPR) mastery in my country, it is difficult for rescuers who have not received professional training to meet the effective frequency and depth requirements of CPR when an emergency occurs. The success rate is much less than 1%. Therefore, if professional auxiliary equipment is used to improve the q...

Problems solved by technology

[0003] Patent CN201342068 discloses a portable auxiliary chest compression detection pad. The device is only equipped with a pressure detection sensor, which cannot provide an intuitive judgment on the depth of compression. At the same time, the device relies on wireless transmission and PC for compression guidance. The communication is unstable and the deployment time is long. , unable to respond quickly

[0004] Patent CN206651984U discloses an auxiliary compression pad for cardiopulmonary resuscitation. The device obtains the depth of chest compression by calculating the data signal of the acceleration / pressure sensor, but the algorithm cannot effectively suppress the drift of the integral baseline

After a long time of high-frequency pressing, the calculation depth will accumulate a large error
