Description

Piston cap manufacturing method of cardiopulmonary resuscitation device}

The present invention relates to a method for manufacturing a piston cap of a CPR device, and more particularly, to a CPR device capable of continuously providing a buffering action for relieving and distributing the pressure acting on a patient's chest during compression of the patient's chest. It relates to a method of manufacturing a piston cap.

Various types of devices for cardiopulmonary resuscitation (CPR) are known in the prior art. One such device is powered by compressed air or breathing gas (Jolife AB, Lund, Sweden; LucasTM). As a unique advantage of the cardiopulmonary resuscitation device, it is possible to transport due to its low weight. Another advantage is the elastic nature of compressed air, whereby gas-powered CPR devices cause less damage to the patient's chest than devices equipped with rigid compression means. The known device can be used as an emergency facility in a life-saving situation. In addition, the known device may be supplied with drive gas from a hospital air supply line, which may be desirable for uninterrupted blows of CPR when a patient is hospitalized.

However, even if the elastic properties of compressed air are used, the material of the compression means itself is hard, so when the patient's chest is compressed, strong pressure is applied to the patient's chest, causing rib fractures and hemothorax during CPR. .

A piston fitting part 711 forming a piston fitting hole 7110 so that the lower end of the piston 310 for compressing the patient's chest with the first mold 50 is fitted, and a lower surface A first protruding member 7120, a second protruding member 7121, a first fitting member 7120a, and a second fitting member 7121a formed on the bottom portion 712 integrally formed pad body 710 Including; molding the pad 700 provided with;
In step c-2),
When the second mold 60 is configured to mold the second vacuum 900, the second mold 60 is provided with a first protruding member insertion hole 911a as the second molding material. After molding the second housing 910b equipped with the first housing 910a and the second protruding member insertion hole 911b, a part of the first housing 910a is divided into a plurality of regions by a partition 915. and forms a plurality of first air flow ports 912a through the plurality of regions of the first housing 910a partitioned by the partition 915, and penetrates the center of the second housing 910b to form a plurality of air flow ports 912a. Forming the second vacuum 900 by forming a second air flow port (912b); manufacturing method of the piston cap of the CPR device, characterized in that it comprises a. According to claim 8,
In step e),
e-1) When the second vacuum 900 is taken out from the second mold 60, the coupling part 70 disposing the second vacuum 900 lower than the pad 700 ;
e-2) In the coupling part 70, the first protruding member 7120 is attached to the first protruding member insertion hole 911a and the second protruding member 7121 is attached to the second protruding member insertion hole 911b, respectively. adjusting the position of the pad 700 so that it is fitted; and
e-3) After applying an adhesive means to the upper portions of the first housing 910a, the second housing 910b, and the partition 915 in the coupling part 70, the first protruding member 7120 is By fitting and coupling the first protruding member insertion hole 911a and the second protruding member 7121 to the second protruding member insertion hole 911b, respectively, the cap is bonded to the pad 700 and the second vacuum 900. Manufacturing a; Piston cap manufacturing method of the CPR device comprising a.
