Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical auxiliary appliances, and in particular relates to a cardiopulmonary resuscitation pressing auxiliary device. Background Art
[0002] Cardiopulmonary resuscitation is a vital emergency rescue technique. When a person's heart stops beating, the blood supply to the brain and other 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. According to the cardiopulmonary resuscitation guidelines, chest compression is performed by pressing the lower 1 / 3 of the patient's sternum. The depth of compression for adults is to make the chest cavity sink 5-6cm. The principle is to increase the pressure in the chest cavity by pressing the chest wall with external force, so that the blood in the heart flows to the aorta and other organs. When the chest cavity rebounds and resets, the peripheral blood returns to the heart, and the cycle repeats itself.
[0003] However, there are the following problems in the actual cardiopulmonary resuscitation process:
[0004] During rescue, the depth of manual chest compression is difficult to control. If the compression is too shallow, the compression effect will not be achieved; if the compression is too deep, it may cause rib and sternum fractures, causing medical injuries and affecting the success rate of rescue; it is impossible to determine whether the chest wall has fully rebounded during manual CPR; manual chest compression too deep can cause fractures and other injuries. Although there are CPR machines that can control the compression depth in clinical practice, they need to be equipped with a power supply or power device when used, which is not convenient to use and affects the usage scenarios.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] Reference Figure 1-Figure 5 As shown, the present embodiment provides a cardiopulmonary resuscitation pressing auxiliary device, comprising a base plate 1, a clamping mechanism is fixedly connected to one side of the top surface of the base plate 1, a longitudinal rod 4 is detachably connected to the clamping mechanism, a plurality of limit holes 11 are evenly spaced on the longitudinal rod 4, a limit ruler 5 is inserted into the limit hole 11, a pressing mechanism is slidably connected to the longitudinal rod 4, the pressing mechanism is located above the limit ruler 5, the pressing mechanism comprises a second slider 6 slidably connected to the longitudinal rod 4, the second slider 6 is located above the limit ruler 5, a pressing plate 7 is provided on one side of the second slider 6, a pressing plate 18 is slidably connected to the pressing plate 7.
[0026] When performing emergency compression, the base plate 1 is placed under the patient, the longitudinal rod 4 is installed on the first slider 3, the second slider 6 is installed on the longitudinal rod 4, the pressing plate 7 can rotate horizontally around the longitudinal rod 4 with the second slider 6 as the center, the position of the longitudinal rod 4 can be adjusted by the clamping mechanism, the position of the pressing plate 7 and the sliding pressing plate 18 are rotated, so that the pressing plate 18 is located at the position of the line connecting the two nipples on the patient's chest, and the limit ruler 5 is installed on the limit hole 11 corresponding to the longitudinal rod 4 according to the required compression depth, and the patient is subjected to external chest compression.
[0027] A further optimized solution is that the clamping mechanism includes a slide rail 2 fixedly connected to the base plate 1, a first slider 3 is slidably connected to the slide rail 2, a socket 8 is provided on the top surface of the first slider 3, a longitudinal rod 4 is arranged in the socket 8, a locking rod 9 is provided on one side of the first slider 3, the locking rod 9 passes through the side wall of the first slider 3 to the socket 8 and abuts against the longitudinal rod 4, and a pull ring 10 is provided on the end of the locking rod 9 located outside the first slider 3.
[0028] When installing the longitudinal rod 4, first pull the locking rod 9 outward through the pull ring 10 to insert the longitudinal rod 4 to the bottom of the insertion hole 8, then release the pull ring 10, and the locking rod 9 will hold the longitudinal rod 4 to limit the longitudinal rod 4. At the same time, the bottom of the longitudinal rod 4 and the first slider 3 are set to the same color, which is convenient for operators to identify and install.
[0029] According to a further optimization scheme, the limit ruler 5 includes an insertion rod end and a scale end. The insertion rod end is provided with a limit protrusion 21 , and the limit protrusion 21 cannot pass through the limit hole 11 .
[0030] By setting a plurality of limit holes 11, the height of the limit ruler 5 is adjusted, and the limit protrusion 21 is used to limit the distance that the limit ruler 5 extends into the limit hole 11, so that the second slider 6 can slide along the longitudinal rod 4.

[0035] By hingedly connecting the pressing plate 7 with the second slider 6, when the chest of some patients is too high, the pressing position can be adjusted to improve the adaptability of the device. The top surface of the pressing plate 18 is a plane, which is convenient for the rescuer to press with the palm of his hand. The bottom surface of the pressing plate 18 is a suction cup-shaped rubber plate. The top surface and the bottom surface of the pressing plate 18 are fixedly connected by a screw. To suit patients of different body shapes, the bottom surface of the pressing plate 18 can be replaced with suction cups of different sizes and thicknesses.
