Description

Technical Field

[0001] The invention belongs to the technical field of cardiopulmonary resuscitation auxiliary devices, and in particular relates to an abdominal compression device used for cardiopulmonary resuscitation. Background Art

[0002] Cardiopulmonary resuscitation is a vital first aid measure. When a person's heart stops suddenly, the blood supply to the brain and other important organs will be interrupted, causing the physiological functions of various organs to fail rapidly. In this case, immediate cardiopulmonary resuscitation can buy precious time for further treatment and rescue, and play a role in saving lives. Cardiopulmonary resuscitation maintains cardiopulmonary function through chest compression and artificial respiration, and reestablishes aerobic blood circulation for patients to ensure blood supply to important organs. Chest compression is an important operation of cardiopulmonary resuscitation technology. According to the latest standard guidelines, chest compression is performed by pressing the midpoint of the line connecting the two nipples at the lower 1 / 3 of the patient's sternum. When pressing an adult, the chest should be sunken 5-6cm at a speed of 100-120 times per minute. Quickly press and reset with external force. Ensure sufficient compression depth during compression to increase the pressure in the chest cavity to squeeze the heart, so that the blood in the heart flows to the aorta and other organs. When resetting, the peripheral blood returns to the heart through the rebound of the chest. Repeat this cycle to maintain the blood supply to important organs.

[0003] However, when the sternum is pressed to cause the chest to collapse, the intrathoracic pressure rises suddenly. In addition to causing the heart to eject blood, the diaphragm also moves downward rapidly, converting part of the compression energy into the force that drives the diaphragm to move. During chest compression, the diaphragm swings up and down rhythmically, pushing the tissues in the abdominal cavity. The patient's belly can be seen to fluctuate rhythmically. During chest compression, the intrathoracic pressure increases, the diaphragm moves downward, and the volume of the chest increases, which will reduce the intrathoracic pressure, thereby reducing the energy of cardiac ejection. The downward movement of the diaphragm affects the effect of chest compression. When the chest rebounds and resets, the intrathoracic pressure decreases, and peripheral blood enters the heart. At the same time, the diaphragm rises, which also reduces the negative pressure in the chest, thereby affecting the return of peripheral blood to the heart. Therefore, during cardiopulmonary resuscitation chest compression, if the diaphragm swing can be limited, the ejection energy of the heart during compression and the blood filling of the heart during chest rebound will be increased, thereby increasing the perfusion pressure of various organs during chest compression, which is greatly beneficial to the quality and effect of compression. Summary of the invention

[0004] The purpose of the present invention is to provide an abdominal compression device for cardiopulmonary resuscitation in view of the deficiencies of the above-mentioned prior art, which limits the movement of the abdominal wall and abdominal organs by compressing the abdomen with continuous and constant force, thereby reducing the movement of the diaphragm during cardiopulmonary resuscitation, thereby reducing the loss of intrathoracic pressure during external chest compression, so that most of the compression energy can be used to squeeze the heart and increase the chest pressure to promote blood circulation, thereby improving the quality and effect of external chest compression.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an abdominal pressure device for cardiopulmonary resuscitation, which includes an abdominal belt, with straps connected to both sides of the abdominal belt, and a pressure block in the middle of the abdominal belt that fits the abdomen of the human body, and a constant force spring is provided at the connection between the strap and the abdominal belt, and the constant force spring is used to ensure that the pressure applied by the pressure block is constant. In use, the two ends of the strap can be connected to each other around the abdomen to fix the abdominal belt and the pressure block; the constant force spring can prevent the pressure from changing due to the fluctuation of the abdominal wall, so that the pressure block can give a constant pressure to the abdomen.

[0006] The pressure block is convex or concave. In use, when the patient's abdomen is in a bulging state, the concave pressure block can be used; and when the patient's abdomen is in a flattened state, the convex pressure block can be used.

[0007] The pressure block is a convex structure, which includes an upper convexity, a middle convexity and a lower convexity. The upper convexity fits with the ribs of the abdomen during use, the middle convexity fits with the abdomen during use, and the lower convexity fits with the pelvis during use. The upper convexity, the middle convexity and the lower convexity are an integrally formed block structure. When in use, the upper convexity fits with the ribs of the abdomen to restrict its movement, the middle convexity fits with the abdomen to restrict its movement, and the lower convexity fits with the pelvis to restrict its movement. Both the upper convexity and the lower convexity are semi-arc structures, so that the abdomen can be more comprehensively compressed and the abdominal movement can be restricted.

[0008] The pressure block has an inwardly concave structure, which is a suction cup structure; this suction cup structure can fit the bulging part of the abdomen when in use.

[0009] It also includes a base plate and a positioning piece, wherein the base plate is made of a hard material, the positioning piece is a plurality of positioning slots opened on both sides of the base plate, and there are binding posts between the positioning slots. During use, the binding strap passes through the positioning slots and is wrapped around the binding posts, and is bound to the base plate through the fixing pieces thereon.

[0010] The abdominal belt is provided with detachable side pressure blocks, which are respectively located on both sides of the pressure block.

[0011] A force gauge is provided at the connection between the abdominal belt and the straps, one end of the force gauge is connected to the abdominal belt, and the other end thereof is connected to a constant force spring, and the other end of the constant force spring is connected to the straps; or, one end of the force gauge is connected to the straps, and the other end thereof is connected to a constant force spring, and the other end of the constant force spring is connected to the abdominal belt; the force gauge is used to monitor changes in the tension of the abdominal belt during pressing.

[0012] The side pressure block is attached to the abdominal belt by Velcro, and when in use, the side pressure block fits with the side wall of the abdomen, thereby reducing the movement of the side abdominal wall during chest compression.

[0013] There are three positioning notches on each side, and the distances from the sides of the bottom plate are distributed in sequence from near to far. This structure can meet the use needs of patients with different abdominal widths.

[0014] After adopting the above structure, the advantages of the present invention compared with the prior art are: the present invention can reduce the movement of the abdominal wall and abdominal organs through the abdominal belt and the pressure block during cardiopulmonary resuscitation, thereby reducing the movement of the diaphragm, avoiding excessive energy loss during compression, and allowing most of the compression energy to increase the chest pressure and squeeze the heart, thereby improving the quality and effect of compression. In addition, since the movement of the diaphragm is reduced, the capacity of the chest cavity is relatively fixed. After the compression efficiency is improved, the depth of external chest compression can be appropriately reduced, thereby reducing the occurrence of complications such as rib fractures and sternum fractures during previous compressions. At the same time, the constant force spring ensures that the force of the pressure device on the abdominal cavity during cardiopulmonary resuscitation is constant, avoiding damage to the internal organs due to changes in the pressure intensity caused by the fluctuation of the abdominal wall during external chest compression.
