Description
Technical field
The present invention relates to external chest compression device field more particularly to a kind of actuated by cams girdle type external chest compression devices.
Background technology
External chest compression is a key link in CPR first aid, and the external chest compression of high quality is to sudden cardiac arrest patient
Generating blood perfusion or even final cycle of restoring has irreplaceable role；In traditional CPR first aid, external chest compression
All by manually implementing, however its quality is often not fully up to expectations.The AHA committees newer 2015 and 2017 type page lung Resuscitation Guidelines
Requirement to external chest compression operation is further harsh, it is desirable that according to pressing depth between 5-6cm, frequency is per minute at 100-120 times, i.e.,
The personnel for having received cardiopulmonary resuscitation training is made also to be difficult to reach such strict requirements；With the consumption of muscle power, manual chest compression
Quality can also further decline.
To solve this predicament, all occur some mechanical external chest compression devices both at home and abroad：Such as patent
" for performing the method and apparatus of alternate breast compressions and decompression " disclosed in 201380055420.3, patent
Disclosed in " cardiac resuscitator " disclosed in 201520047669.6, patent 201420629694.0 " critically ill patient heart compressions device "
Deng.But existing mechanical compression device all works in a manner that patient's breastbone is oppressed in vertical precession, therefore, there is that it is common
Shortcoming：
1st, pressing force concentrates on the sub-fraction of patient's breastbone, be easy to cause patients with fractures with dampening；
2nd, in case of motor is out of control, cause according to pressing depth excessive, mortal injury can be caused to patient；
3rd, under working condition, huge Mechanical Driven module is in above patient chest, makes the type device that can not carry on a shoulder pole
The narrow environments such as frame, ambulance are widely applied, and also hamper medical staff and other first aids of patient are operated.
Therefore, it is necessary to explore a kind of new external chest compression device, problem above is overcome.
Invention content
The present invention provides a kind of actuated by cams girdle type external chest compression devices, and present invention reduces patients with fractures and contusion
Risk, and better blood perfusion effect is generated, the narrow environments such as stretcher transhipment, ambulance is suitble to use, it is described below：
A kind of actuated by cams girdle type external chest compression device, the external chest compression device include：Backboard,
Circulating type band is provided on the backboard, the circulating type band is used to that patient to be made to generate blood perfusion；
The head lay down location of the backboard is provided with head recess, the head recess is used to keep the air flue of patient
It is open；
Several retainer rings are provided between the circulating type band and the head recess on the backboard, it is described
Retainer ring is used to that shoulder neck to be fixed；
Several cams are internally provided in the backboard, transmission belt, and the transmission are provided on the cam
Band is through the circulating type band；
Motor is additionally provided in the inside of the backboard, the motor drives the rotation of the cam.
Further, the long side of the cam and short side oppress the transmission belt in turn, cause and the transmission band connection
The circulating type band in periodically push or relaxation state.
Preferably, the both sides of the backboard are provided with several Portable handles.
During specific implementation, the peripheral shape of the cam is in sector structure.
Preferably, the model SAMSR TSM24 of the motor.
During specific implementation, when the number of the cam is 2, the long side and short side of the cam be respectively 3.5cm and
1cm is according to pressing depth 5cm.
Preferably, the quantity of the retainer ring is 2；The quantity of the Portable handle is 4；The cam and the electricity
The quantity of machine matches.
The advantageous effect of technical solution provided by the invention is：
1) present invention is using girdle type pressing structure, flexible with patient and come into contact in a large area, and pressure is almost distributed in entirely
Chest, to the injury smaller of body；
2) head position of the present invention when patient lies down, devises a groove, and patient airway can be made to keep opening；
3) present invention uses cam-type driving structure, simple and reliable, ensure that maximum according to pressing depth not from hardware configuration
More than long side and the diameter difference of short side (such as：5cm), it avoids and is pressed caused by electronic control system is out of control excessively to patient
Caused by mortal injury, it is therefore safer；
4) present invention passes through the design to cam peripheral shape, you can generates different by corrugating；For example, by using in Fig. 3
Cam face, can make that pushing process is more smooth, the most deep position of pressing is kept for the longer time, loosens process faster, so as to
It reduces patients with fractures and dampens risk, and generate better blood perfusion effect；
5) present invention is compared with existing external chest compression device, and compact-sized, " head " of neither one burden is more suitable for
It is used in narrow environments such as stretcher transhipment, ambulance first aids, does not influence other operations of medical staff.
