Portable medical first-aid automatic cardiac pressing device

Abstract

The invention relates to a portable medical first-aid automatic cardiac pressing device which is characterized by comprising a fixed support, a pressing mechanism and control equipment. The fixed support is an n-shaped support; the pressing mechanism is composed of two pressing plates capable of moving up and down and is driven by a stepping motor to do reciprocating pressing motions, and the pressing height and frequency are limited by a mechanical structure; the control equipment comprises a stepping motor driver, a voltage stabilization storage battery and a PLC; the control equipment has astarting function, a control function and an energy module, and the control equipment is mainly used for starting the stepping motor driver to drive the stepping motor, adjusting the rotating speed output of the motor and providing power for the whole system. The cardiac resuscitation pressing device can conduct cardiac resuscitation on a patient according to the standard cardiac resuscitation pressing force and frequency, and the problems that the cardiac resuscitation rhythm is disordered, and the force and the depth do not meet the standard due to the fact that medical staff are not skilled in technique and physical strength is reduced are solved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a portable medical first-aid automatic heart pressing device. Background technique [0002] Cardiac compression is a measure of first aid. If the patient is in shock, or has impaired consciousness, does not respond to calls, etc., but faints, this method can be used for first aid. [0003] The specific method is as follows: [0004] 1. Lay the patient on his back, untie the collar, and open the airway by raising the head and raising the chin. The rescuer is on the patient's left. [0005] 2. The pressing site is the junction of the middle 1 / 3 of the sternum and the lower 1 / 3 of the sternum. [0006] 3. Put the heel of the left palm close to the compression area, and put the heel of the right palm on the back of the left hand, so that all fingers are separated from the chest wall. [0007] 4. The rescuer's arms should be straightened, and the shoulders should be di...

AI Technical Summary

Problems solved by technology

[0012] It can be seen from the above that cardiac compression resuscitation requires the rescuer to have relatively accurate control of the force and frequency, but people are not machines. With rapid compression, the physical strength of the person will decrease, and the frequency of compression will be disordered. The intensity and depth of compression It will also have an impact, and artificial respiration cannot be performed according to the frequency; a skilled rescuer who presses the heart has the above problems, and an unskilled rescuer or a person who does not understand at all rescues a patient who needs cardiac compression. It is more difficult to control the pressure and the rhythm of artificial respiration. In severe cases, it will aggravate the patient's condition and put the cart before the horse. Therefore, a standard heart compression first aid device is needed.
