Description
Technical Field
The utility model relates to a surgery first aid technical field specifically is a thoracic surgery is cardiopulmonary resuscitation supplementary press device for first aid.
Background
In hospital emergency, when a patient suffering from sudden cardiac arrest is encountered, cardiopulmonary resuscitation needs to be applied to the patient, and if the patient is not rescued and resuscitated in time, irreversible damage to the brain and other important organs and tissues of the human body of the patient can be caused. It is common practice to compress the chest or heart on site by pressing the patient's lower sternum halves with both hands, allowing blood flow to facilitate resuscitation of the heart.
The external chest compression method consumes a large amount of physical power of an operator, so that the compression quality of the operator begins to decrease (the frequency and amplitude and the chest wall resetting condition are not ideal) after the compression begins for 2 minutes, the resuscitation success rate can be reduced, the compression interruption can be caused by the replacement of the operator, the coronary artery and cerebral blood flow can be interrupted too much, and the resuscitation success rate is obviously reduced. Therefore, there is a need for a chest compression emergency device that can replace or assist the operator to address these problems.
In the prior art, an emergency pressing device exists, for example, the invention patent 'cardiac pressing device for emergency treatment in thoracic surgery' with application number 201910190686.8 discloses a pressing device which is placed above a patient and a pressing plate, the position of the pressing device is adjusted through a walking wheel and a movable cross rod, the height of a pressing unit is adjusted through a vertical extending device, and the pressing device can effectively adapt to patients with different fat and thin bodies to carry out rescue operation. However, in the cardiac resuscitation, a large force needs to be applied to the chest of a patient, the chest needs to be pressed down by 4-5cm according to standard requirements, the position can be accurately adjusted during manual operation, but the light weight of the device enables the reaction force of pressing to easily enable the whole pressing device to jump up and displace, and further the pressing position is inaccurate. Meanwhile, the structure of the pressing unit also makes it easy to cause injury to the human body. Another mechanical type cardiopulmonary resuscitation among the prior art machine will press the unit restriction to pressing the position through the magic tape, and the magic tape is walked around patient's back and is carried out the parcel formula fixed, and the small and exquisite portable of this kind of device exerts pressure the also effectual effect of exerting pressure of having improved to the thorax through the magic tape jointly, but this will hardly realize effectual pressing the degree of depth, and it is very little to fat patient even partial female patient effect.
