Portable cardiac compression apparatus that can intuitively measure and control the compression depth

Abstract

The invention discloses a cardiac compression apparatus that can intuitively measure and control the compression depth. The cardiac compression apparatus comprises a compressing head, a compressing cross rod, and a handle for a rescuer to hold. The compressing head is connected with the compressing cross rod, the first end of the compressing cross rod is connected with a supporting part, the second end of the compressing cross rod is connected with a vertical floating contact bottom rod, and the handles are arranged on opposite sides of the compressing head; the compressing head moves up and down along with at least one side of the handle; a measuring sleeve rod is sleeved on the lower part of the floating contact bottom rod at the second end of the pressing cross rod, which is provided with a length scale, the length scale whose reading reflects the displacement distance between the measuring sleeve rod and the floating contact bottom rod, equal to the moving distance of the pressinghead corresponding to the displacement distance. With the cardiac compression apparatus that can intuitively measure and control the compression depth, the depth value can be conveniently measured, the operation can be simplified and the physical strength can be saved, and the apparatus is suitable for the popularization of hospitals and public places.

Description

technical field [0001] The invention belongs to the technical field of medical emergency equipment, and in particular relates to a portable heart compressor capable of visually observing and controlling the compression depth. Background technique [0002] Sudden cardiac arrest leads to the sudden cessation of effective heart pump function and blood circulation, which will immediately cause severe ischemia, hypoxia and metabolic disorders of the tissue cells of the whole body, and will cause irreversible damage to the patient's brain and other vital organs and tissues after 4 to 8 minutes. Therefore, the rescue must be carried out against time, and even a minute or a few seconds ahead may be of great significance. [0003] According to the "China Cardiovascular Disease Report 2016" released by the National Center for Cardiovascular Diseases, the number of sudden cardiac arrest deaths in my country exceeds 500,000 each year, and more than 60% to 70% of them occur outside medic...

AI Technical Summary

Problems solved by technology

In the above process, you need to remember two values ​​(compression initial reading and compression end reading), and the compression initial scale value and compression end scale value are different according to the difference of the patient's chest thickness, which are random values ​​(according to the patient's chest thickness). different thicknesses), it is impossible to display exactly the limit value of the compression depth or an integer multiple of the limit value of the compression depth, and generally it is impossible to display exactly zero; therefore, the compression depth readings of the existing depressor measuring devices are not intuitive and need to be converted , it is not conducive to rescue against time and seconds, and it is easy to make mistakes in conversion when panicked;

[0013] 3. The entire mechanical press must be connected with the back lying part (bed) before it can be used. The overall volume is large and the weight is also heavy, so it is only suitable for deployment in hospitals, not in public places (there are no public places) Matching bed), and not suitable for ordinary households (due to too much space and high cost to equip)

[0014] It can be seen that there are deficiencies in the existing above-mentioned three emergency compression methods. Due to the above-mentioned many problems and difficulties, among the total number of about 500,000 people who suffer from cardiac arrest in my country every year, less than 1% of them can be rescued.
