The invention discloses a cardiopulmonary resuscitation presser capable of transmitting X rays. The cardiopulmonary resuscitation presser comprises a pressing part and an electronic control part; thepressing part and the electronic control part are of a split structure; the pressing part is made of a non-metal material and comprises a pressing head, an air cylinder and a pneumatic control valve,the pressing head is connected with the ejection end of the air cylinder, and the pneumatic control valve is used for controlling to charge or discharge gases into a cylinder body of the air cylinderso as to drive the pressing head to perform a pressing action; an air inlet of the pneumatic control valve is connected with an air source by an air inlet pipe; and the electronic control part communicates with a chamber of the pneumatic control valve by a pneumatic control pipe to control a valve element of the pneumatic control valve to reciprocate on a gas charging position and a gas discharging position, and furthermore, a piston rod in the air cylinder is controlled to be ejected or shrunk. The cardiopulmonary resuscitation presser capable of transmitting X rays, disclosed by the invention, meets an application demand of a patient for a clinic environment requiring X ray transmittance and makes up the technical blank in clinic at present.
Description
technical field [0001] The invention relates to the technical field of cardiopulmonary resuscitation pressing devices, in particular to an X-ray-permeable cardiopulmonary resuscitation pressing device. Background technique [0002] Cardiopulmonary resuscitation compressor (hereinafter referred to as compressor) is one of the most commonly used and most important equipment for medical emergency. Compressors can be divided into two categories: pneumatic and electric according to different powers. However, both pneumatic and electric pressers cannot be directly used in clinical environments that require X-ray fluoroscopy due to the inclusion of metal parts. [0003] And X-ray fluoroscopy is often the clinical environment that is often faced in the first aid and rescue process. If the presser is excluded during the X-ray detection process, precious rescue time will be delayed. In addition, operations in the cardiac catheterization laboratory need to be performed under the guid...
