Problems solved by technology

[0004] 1. The pressing force is concentrated on a small part of the patient's sternum, which may easily cause fractures and contusions;
[0005] 2. If the motor is out of control, resulting in excessive compression depth, it will cause fatal injury to the patient;
[0006] 3. In the working state, the huge mechanical drive module is above the patient's chest, which makes this type of device unable to be popularized and applied in narrow environments such as stretchers and ambulances, and also hinders other first aid operations for patients by medical staff

Embodiment 1

[0038] A cam-actuated belt-type chest compression device, see figure 1 and figure 2 , the cam-driven belt-type chest compression device includes: a backboard 1 , a wrap-around belt 2 , a head groove 3 , a fixing ring 4 , a portable handle 5 , a transmission belt 6 , a cam 7 and a motor 8 .

[0039] A wrap-around strap 2 is arranged on the backboard 1, a head groove 3 is arranged at the place where the head of the backboard 1 is placed, and a wrap-around strap 2 and the head groove 3 are arranged on the backboard 1 There are several fixed rings 4; several portable handles 5 are arranged on both sides of the backboard 1; several cams 7 are arranged inside the backboard 1, and a transmission belt 6 is arranged on the cam 7, and the transmission belt 6 runs through the Wrap-around belt 2; a motor 8 is provided inside the backboard 1, and the motor 8 drives the rotation of the cam 7, and the number of the cam 7 matches the number of the motor 8.

[0040] In summary, the embodim...

Embodiment 2

[0042] Combine below Figure 1-Figure 4 , the specific device model further introduces the solution in Embodiment 1, see the following description for details:

[0043] see figure 1 , the cam-driven belt-type chest compression device uses the surrounding belt 2 to press the patient's chest, and the patient can generate blood flow perfusion through the loosening or tightening of the surrounding belt 2; the pressure is widely distributed on a larger contact area , less harm to the patient.

[0044] The position of the head of the patient when lying on the backboard 1, a head groove 3 is designed to keep the airway of the patient open; The neck is fixed; a portable handle 5 is designed to facilitate the handling of emergency personnel.

[0045] see figure 2 , motor 8 (the preferred model is the motor of SAMSR TSM24) drives cam 7 to rotate by rotation, and the long side and short side of cam 7 press transmission belt 6 in turn, causing the encircling belt 2 that is connected...

Abstract

The invention discloses a cam-driven bandage-type external chest compression device, and relates to the field of external chest compression devices. The cam-driven bandage-type external chest compression device comprises a backboard, and an encircling-type bandage is arranged on the backboard, and is used for allowing a patient to generate blood perfusion; a head groove is formed in the head placing portion of the backboard, and is used for allowing an air way of the patient to be kept open; a plurality of fixing rings are arranged between the encircling-type bandage on the backboard and the head groove, and are used for fixing a shoulder neck part; a plurality of cams are arranged inside the backboard, and a conveying belt is arranged on the cams and penetrates through the encircling-typebandage; motors are also arranged inside the backboard and drive the cams to rotate. According to the cam-driven bandage-type external chest compression device, a bandage-type compression structure is adopted and is in flexible and large-area contact with the patient, pressure is nearly distributed on the whole chest, and harm to the body is smaller; fracture and contusion risks of the patient are reduced, and the better blood perfusion effect is generated.

Description

technical field [0001] The invention relates to the field of chest compression devices, in particular to a cam-driven belt-type chest compression device. Background technique [0002] Chest compression is a key link in cardiopulmonary resuscitation first aid. High-quality chest compression plays an irreplaceable role in generating blood perfusion and eventually restoring circulation in patients with cardiac arrest; in traditional cardiopulmonary resuscitation first aid, chest compressions are performed by Manual implementation, however, is often not of satisfactory quality. The 2015 and 2017 CPR guidelines updated by the AHA Committee have increasingly stringent requirements for chest compression operations, requiring a compression depth of 5-6cm and a frequency of 100-120 times per minute, which is difficult even for personnel trained in CPR Such strict requirements; with the exhaustion of physical strength, the quality of manual chest compressions will further decline. ...
