Description

Abdominal pressurizing device for cardiopulmonary resuscitation

Technical Field

The invention belongs to the technical field of cardiopulmonary resuscitation auxiliary devices, and particularly relates to an abdomen pressurizing device for cardiopulmonary resuscitation.

Background

Cardiopulmonary resuscitation is a vital emergency procedure, and when a person's heart is suddenly stopped, the blood supply to the brain and other vital organs will be interrupted, resulting in rapid failure of physiological functions of the various organs. In this case, immediate cardiopulmonary resuscitation can be used to fight for valuable time for further treatment and rescue, which serves as a life saving function. Cardiopulmonary resuscitation maintains cardiopulmonary function by chest compression and artificial respiration, reestablishes aerobic blood circulation for the patient to ensure blood supply to important viscera. Chest compression is an important operation of cardiopulmonary resuscitation techniques, and according to the latest standard guidelines, chest compression is performed by pressing the midpoint of the line connecting the two nipples at 1/3 of the middle and lower part of the sternum of a patient, and when an adult is pressed, the chest is depressed 5-6cm at a rate of 100-120 times per minute. The device is pressed and reset rapidly by external force. The pressure ensures enough pressing depth to increase the pressure in the chest to squeeze the heart, so that the blood in the heart flows to the aorta and other organs. During the resetting, the peripheral blood returns to the heart through the rebound of the thoracic cage. The blood supply to the vital organs is maintained over and over again.

However, when the chest is depressed by pressing the sternum, the intrathoracic pressure is suddenly increased, and besides the outward ejection of the heart, the diaphragm is rapidly moved downwards, so that part of the energy of the pressing is converted into the upward and downward swinging of the diaphragm rhythms when the chest is pressed by the force pushing the diaphragm to move, the tissues in the abdominal cavity are pushed, and the rhythmic fluctuation of the belly of the patient can be seen. When chest is pressed, the pressure in the chest is increased, the diaphragm moves downwards, the volume of the chest is increased, and then the pressure in the chest is reduced, so that the heart ejection energy is reduced, and the effect of chest pressing is influenced by the downward movement of the diaphragm. When the chest is rebound and reset, the intrathoracic pressure is reduced and peripheral blood enters the heart. Meanwhile, the diaphragm can be lifted up, and the negative pressure of the chest cavity is reduced, so that the reflux of peripheral blood to the heart is influenced. Therefore, when the chest and lung are resuscitated and the chest and the heart is pressed, if the diaphragm can be limited to swing, the ejection energy of the heart during pressing and the blood filling of the heart during chest rebound can be improved, so that the perfusion pressure of each organ during chest and lung are improved, and the quality and effect of pressing are greatly facilitated.

Disclosure of Invention

The invention aims at overcoming the defects of the prior art, and provides an abdomen pressurizing device for cardiopulmonary resuscitation, which can compress the heart and increase the chest pressure to push the blood circulation by continuously and constantly pressing the abdomen to limit the movement of the abdominal wall and the internal organs of the abdomen, thereby reducing the movement of diaphragm muscle during cardiopulmonary resuscitation, reducing the loss of pressure in the chest during chest compression, and improving the quality and effect of chest compression.

In order to achieve the purpose, the technical scheme is that the abdomen pressurizing device for cardiopulmonary resuscitation comprises an abdominal belt, wherein the two sides of the abdominal belt are connected with binding belts, the middle part of the abdominal belt is provided with a pressurizing block attached to the abdomen of a human body, and a constant force spring is arranged at the joint of the binding belts and the abdominal belt and used for ensuring that the pressure exerted by the pressurizing block is constant. The constant force spring can prevent the pressure from changing due to fluctuation of the abdominal wall, and the pressurizing block can apply constant pressure to the abdomen.

The side pressure blocks are adhered to the bellyband through the magic tape. The side pressing block is attached to the side wall of the abdomen when in use, so that the movement of the side abdominal wall when the chest is pressed is reduced.

The number of the positioning notches is three at two sides respectively, and the distances between the positioning notches and the side face of the bottom plate are sequentially distributed from near to far. The structure can meet the use requirements of patients with different abdomen widths.

By adopting the structure, compared with the prior art, the heart-lung recovery device has the advantages that the movement of the abdominal wall and organs in the abdominal cavity can be reduced through the bellyband and the pressurizing block when the heart-lung recovery is carried out, so that the movement of diaphragm muscles is reduced, the excessive loss of energy during pressing is avoided, the chest pressure can be mostly improved by the pressing energy, the heart is extruded, and the pressing quality and effect are improved. And because the movement of diaphragm muscle is reduced, the capacity of chest cavity is relatively fixed, after the pressing efficiency is raised, the depth of chest compression can be properly reduced, so that the occurrence of complications of rib fracture, sternal fracture and the like in the past pressing process can be reduced. Meanwhile, the constant force spring ensures that the pressurizing force of the pressurizing device to the abdominal cavity is constant during cardiopulmonary resuscitation, and avoids the damage to viscera caused by the change of the pressurizing force caused by the fluctuation of the abdominal wall during chest compression.
