Title:
PNEUMATIC CARDIOPULMONARY RESUSCITATION COMPRESSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/073614
Kind Code:
A1
Abstract:
Provided is a pneumatic cardiopulmonary resuscitation compression apparatus, comprising a cylinder (1) and a buffer chamber (2), the buffer chamber (2) being arranged adjacent to the cylinder (1); the cylinder (1) is internally provided with a piston (3), a compression head (4) is connected to the ejection end of the piston (3), the air inlet port of the cylinder (1) is connected to the air supply port (51) of a control valve (5), and the air inlet (52) of the control valve (5) is connected to a air supply (7) by means of an air inlet tube (6); a bronchial tube (8) is arranged at one end of the air inlet tube (6) adjacent to the control valve (5), and the bronchial tube (8) connects the air inlet tube (6) to the buffer chamber (2). The pneumatic cardiopulmonary resuscitation compression apparatus not only solves the technical problem of insufficient air inflation in the cylinder caused by air resistance or flow restriction, which has long plagued pneumatic compression devices, but also improves the clinical application environment of the pneumatic compression device, such that the clinical effectiveness of the compression device can be guaranteed under different air supplies.
