Description

Technical Field

[0001] The present invention relates to a manual cardiopulmonary resuscitator, belonging to the technical field of medical equipment. Background Art

[0002] Cardiopulmonary resuscitation (CPR) is an emergency measure to maintain blood circulation and oxygen supply through manual operation when cardiac arrest or respiratory arrest occurs, which can buy precious rescue time for patients. Standard CPR requires the rescuer to cross the hands and place them at the lower edge of the patient's sternum, and press vertically with the gravity of the upper body, with a depth of 5-6 cm and a frequency of 100-120 times per minute. However, it is often difficult for those without professional training to meet the standards. When the compression is too shallow (<5 cm), it will lead to insufficient cardiac compression, reduced blood pumping efficiency, insufficient blood supply to vital organs, and difficulty in restoring the spontaneous heartbeat of the heart. When the compression is too deep (>6 cm), it may cause complications such as rib fractures and pneumothorax, and affect the blood return of the heart. In addition, the standard CPR posture (hands crossed and overlapped) is likely to cause finger pain to the rescuer, and even professional personnel will find it difficult to maintain the standard operation due to physical exhaustion and discomfort in the kneeling position after a long time of compression. Therefore, accurately controlling the compression depth and frequency is the key to the success of CPR, but it is extremely challenging for non-professionals.

[0003] Chinese Patent No. 202420710431.6 provides a manual cardiopulmonary resuscitator that can control the compression depth. This patent provides a manual cardiopulmonary resuscitator for controlling the CPR compression depth. However, it is found in use that this device has the following defects: 1. The original intention of this device is that when the pressing column presses against the bottom plate, the stroke of the pressing column (i.e., the length of the pressing column) is the compression depth, and the compression depth is controlled by the length of the pressing column. However, it is found in use that when pressing to the bottom, the pressing handle at the top of the pressing column will press against the bottom plate, and the applied pressure is transmitted to the support rod. At this time, the support rod will bend, causing the bottom plate to sink. At this time, the pressing distance will exceed the length of the pressing column, that is, the compression depth is the length of the pressing column + the sinking height of the bottom plate, resulting in the compression depth exceeding the standard and failing to achieve the purpose of controlling the compression depth of this patent; 2. When pressing, the pressing handle and the bottom plate are in sudden rigid contact, and the feedback time transmitted to the pressing person is too short, making it difficult for the pressing person to receive force in time, which is likely to cause harm to the patient, and the rigid contact between the pressing handle and the bottom plate is likely to cause damage to the bottom plate. Summary of the Invention

[0004] The purpose of the present invention is to provide a manual cardiopulmonary resuscitator that overcomes the above-mentioned drawbacks and can ensure the compression depth and compression effect.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: A manual cardiopulmonary resuscitator includes a support plate, a strap, a hard bracket and a back plate. A through hole is provided in the middle of the support plate, and a pressing column is inserted through the through hole. A pressing plate is provided at the top of the pressing column, and a pressing head is provided at the bottom of the pressing column. The circumference of the pressing plate is larger than that of the pressing column. An elastic member is sleeved on the pressing column connected below the pressing plate. The elastic member is located between the pressing plate and the support plate, and the pressing head is located below the support plate. The support plate is detachably connected to the back plate through a hard bracket. The strap is divided into a left strap and a right strap. The upper ends of the left strap and the right strap are respectively detachably connected to the left and right ends of the bottom plate, and the bottom ends of the left strap and the right strap are respectively detachably connected to the back plate. Further, the hard bracket includes a left support rod and a right support rod. Positioning rods are respectively provided at the tops of the left support rod and the right support rod, and the bottom ends of the left support rod and the right support rod are respectively supported on the left and right ends of the back plate. Transverse position adjusting mechanisms for adjusting the positions of the tops of the hard brackets are respectively provided at both ends of the support plate. The transverse position adjusting mechanism includes a base, a U-shaped elastic piece, positioning rods provided at the tops of the left support rod and the right support rod, and a cover plate. The base is fixed on the top of the support plate. A horizontal long hole is provided on the side of the base. The positioning rod is inserted through the long hole, and the positioning rod can slide back and forth along the axial direction of the long hole. One single-side arm of the U-shaped elastic piece is fixedly connected to the top of the support plate, and the other arm of the U-shaped elastic piece is fixedly connected to the cover plate. A plurality of inclined and bottom-open clamping grooves are provided on the cover plate, and the cover plate realizes buckling and locking of the positioning rod through the cooperation of the clamping grooves and the positioning rod. Further, the length of the pressing column above the support plate is between 5.5 - 6.5 cm. Further, the elastic member is a corrugated spring or a compression spring, and the length of the corrugated spring or the compression spring is between 2 - 3 cm.

[0006] The positive and beneficial technical effects of the present invention are as follows: 1. By providing a hard support, the support plate is fully supported by the non-deformable left support rod and right support rod during pressing, so that the depth of each press can be the same as the height of the pressing rod, and the depth of each press can reach the standard, ensuring the pressing effect. 2. The provided transverse position adjusting mechanism can conveniently adjust the position of the support rod on the support plate, thereby adjusting the height of the support plate to adapt to patients of different body types. 3. The spring sleeved on the pressing column connected below the pressing plate plays a role of micro-damping when the pressing is almost in place, which can prompt the pressing personnel that the pressing depth is almost in place, and the spring itself can also prevent the pressing column from continuing to descend, ensuring that the pressing depth is within the standard range. 4. By providing a plurality of parallel card slots at both ends of the back plate, the bottom ends of the left support rod and the right support rod are clamped in the card slots, and it is also possible to simply adjust the inclination of the left support rod and the right support rod to adjust the height of the bottom plate of the presser to adapt to the height of the thoracic cavity of different people. 5. The present invention can also adopt pressing methods such as kneeling on both knees, kneeling on one knee, and leaning over to press. When pressing in a standing position, since the presser can apply the weight of the upper body to the pressing column, it is easy to cause the pressing depth to exceed the standard. The feedback mechanism and hard support of the elastic part provided in the present invention can fundamentally prevent the situation of pressing too deep. BRIEF DESCRIPTION OF THE DRAWINGS
