Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a cardiopulmonary resuscitation machine control system. Background Technology

[0002] In traditional cardiopulmonary resuscitation (CPR), the operator typically uses both hands to press on the patient's chest. The required compression depth is 3-5 cm, and the compression rate is 100-120 times per minute. This requires considerable effort, and in practice, the operator's arms are often not fully extended, resulting in uneven force application. Therefore, an automated cardiopulmonary resuscitation (APR) device is needed to perform chest compressions.

[0003] Currently, existing automated cardiopulmonary resuscitation (CPR) devices typically involve fixing the device in place and using a cylinder to drive the compression unit to perform chest compressions. However, this method has limitations when used on different patients. Because the compression depth is fixed, the quality of chest compressions varies from patient to patient, posing a risk of sternal fracture. Additionally, the excessive reaction force during compressions makes it difficult to fix the patient in place. Therefore, we propose a CPR machine control system. Summary of the Invention

[0017] Beneficial effects

[0018] This invention provides a control system for a cardiopulmonary resuscitation machine. It has the following beneficial effects:

[0019] (1) The cardiopulmonary resuscitation machine control system based on adaptive impedance adjustment uses the adjustment device and resuscitation components to adjust the distance of the positioning slide slide according to different patients, thereby adjusting the distance of the compression spring of the compression body. By adjusting the elastic coefficient and compression amount of the compression spring, the magnitude of the compression force of the compression body can be adjusted, so that the device can improve the quality of chest compressions and reduce the risk of sternal fracture when performing compressions on different patients.

[0020] (2) The cardiopulmonary resuscitation machine control system based on adaptive impedance adjustment uses protective auxiliary components, which enables the device to adjust the height of the support column and the height of the connector when used on different patients. Then, under the action of the pull rope, the elastic pad is stretched upward, which makes it easier for the elastic pad to limit the chest of different patients, ensuring the stability of the patient when being pressed, and at the same time protecting the patient from external chest compressions, further reducing the risk of sternal fracture.

[0021] (3) The cardiopulmonary resuscitation machine control system based on adaptive impedance adjustment uses the resuscitation components so that when the device is pressing the patient, the guide rod can slide in the limiting groove when the pressure rod compresses the spring, thereby allowing the roller to open to both sides and roll and press the patient's chest on both sides, further improving the quality of chest compressions and further improving the stability of the patient when performing chest compressions.

[0029] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-5 This invention proposes a cardiopulmonary resuscitation (CPR) machine control system, including an adjustable support column 1. A protective auxiliary component 2 is installed on the outer wall of the adjustable support column 1. By using the protective auxiliary component 2, the height of the support column 1 can be adjusted to limit the chest position of different patients, ensuring stability during chest compressions and protecting against chest compressions, thus reducing the risk of sternal fracture. A top plate 3 is fixedly connected to the top of the adjustable support column 1. An adjustment device 4 is installed above the protective auxiliary component 2, allowing the device to adjust the downward pressure of the resuscitation component 5. The distance allows the device to improve the quality of chest compressions and reduce the risk of sternal fractures when performing chest compressions on different patients. The adjustment device 4 includes a rotary motor 41, which is fixedly connected to the outer wall of the top plate 3. A rotating shaft 42 is fixedly connected to the output shaft of the rotary motor 41. A rotating component 43 is fixedly connected to the end of the rotating shaft 42 away from the rotary motor 41. A resuscitation component 5 is provided below the adjustment device 4. By using the resuscitation component 5, the device can press and squeeze both sides of the patient's chest during chest compressions, improving the quality of chest compressions and increasing the stability of the patient during chest compressions.

[0032] In an embodiment of the present invention, in order to protect patients before chest compressions according to different patients and reduce the risk of sternal fracture, specifically, a fixed suction cup 101 is fixedly connected to the bottom of the adjustable support column 1 to improve the stability of the adjustable support column 1. The protective auxiliary component 2 includes a fixing member 21, an elastic pad 22 is fixedly connected to the fixing member 21, a pressing pad 23 is fixedly connected to the outer wall of the elastic pad 22, and a pull rope 24 is fixedly connected to the outer wall of the elastic pad 22. The end of the pull rope 24 away from the elastic pad 22 is fixedly connected to the connector 25, and the connector 25 is fixedly connected to the telescopic end of the adjustable support column 1. By adjusting the telescopic end of the support column 1, the position of the connector 25 can be raised or lowered, thereby driving the pull rope 24 to lift the position of the elastic pad 22, so that the elastic pad 22 can protect different patients and fix the patient's position, improving the stability during subsequent chest compressions.

[0033] Furthermore, in order to adjust the compression distance of the resuscitation component 5 according to different patients, and to facilitate subsequent adjustment of the compression force and depth of the resuscitation component 5 to improve the quality of chest compressions, specifically, a positioning component 44 is provided above the resuscitation component 5, and a through groove 31 is opened on the outer wall of the top plate 3. The positioning component 44 is fixedly connected to the through groove 31. A positioning slide plate 45 is provided below the positioning component 44. The rotating component 43 includes a turntable 431. A small motor 433 is fixedly connected to the outer wall of the turntable 431. A lead screw 432 is fixedly connected to the output shaft of the small motor 433. A sliding block 434 is threadedly connected to the lead screw 432. The sliding block 434 is limited by the groove of the turntable 431, so that the lead screw 432 can stably drive the sliding block 434 to slide when rotating. A round rod 435 is fixedly connected to the outer wall of the sliding block 434. The end of the round rod 435 away from the sliding block 434 is fixedly connected to the outer wall of the sliding block 434. A fixed connection is established with a limiting ring 436. A round rod 435 is slidably connected in a limiting member 437. A vertical rod 438 is fixedly connected to the bottom outer wall of the limiting member 437. The vertical rod 438 passes through the positioning member 44 and is slidably connected to the positioning member 44. The output shaft of the small motor 433 rotates, driving the lead screw 432 to rotate, causing the sliding block 434 to move the round rod 435, adjusting its distance from the center of the turntable 431. Then, the output end of the rotary motor 41 rotates, causing the rotating shaft 42 to drive the turntable 431 to rotate, which in turn drives the round rod 435 to rotate. Under the action of the limiting member 437 and the positioning member 44, the vertical rod 438 is driven to rise and fall stably. At the same time, the distance between the round rod 435 and the center of the turntable 431 is adjusted to adjust the lifting distance of the vertical rod 438, thereby adjusting the sliding distance of the positioning slide plate 45, achieving the effect of adjusting the compression depth, and thus improving the quality of chest compressions.

[0034] Furthermore, to further improve the quality of chest compressions and adjust the compression pressure according to different patients, the resuscitation assembly 5 specifically includes a fixed cylinder 51, which is fixedly connected to the bottom of the positioning slide plate 45. A pad 52 is slidably connected to the inner wall of the fixed cylinder 51, and the pad 52 is elastically connected to the inner wall of the positioning slide plate 45 by a compression spring 53. A pressure rod 54 is fixedly connected to the side of the pad 52 away from the compression spring 53, and a compression body 55 is fixedly connected to the bottom of the pressure rod 54. A hinge rod 56 is hinged to the outer wall of the fixed cylinder 51, and a roller 57 is rotatably connected to the end of the hinge rod 56 away from the fixed cylinder 51. A crossbar 58 is fixedly connected to the outer wall of the pressure rod 54, and a guide rod 5 is fixedly connected to the end of the crossbar 58 away from the pressure rod 54. 9. A limiting groove 561 is provided on the outer wall of the hinge rod 56, and the limiting groove 561 is slidably connected to the guide rod 59. As the positioning slide plate 45 descends, it drives the fixed cylinder 51 to descend, which in turn drives the compression body 55 to press the chest of the human body. At this time, the pressure rod 54 moves upward, which drives the pad 52 to compress the compression spring 53. By adjusting the lifting distance of the vertical rod 438, the lowering distance of the fixed cylinder 51 can be adjusted, so that the compression distance of the compression spring 53 can be adjusted. According to the compression amount and elastic coefficient of the compression spring 53, the force of the compression body 55 pressing the patient's chest can be controlled, and the force gradually increases, further reducing the possibility of chest fractures and further improving the quality of chest compressions.

[0035] It should be noted that when the pressure rod 54 compresses and tightens the spring 53, it can drive the guide rod 59 to slide in the limiting groove 561, thereby allowing the roller 57 to open to both sides and roll and press on both sides of the patient's chest, further improving the quality of chest compressions and further improving the stability of the patient when performing chest compressions.

[0036] In this invention, during use, the position of the connecting piece 25 is raised or lowered by adjusting the telescopic end of the support column 1 according to different patients, thereby driving the pull rope 24 to lift the position of the elastic pad 22, so that the elastic pad 22 can protect different patients and fix the position of the patients. Then, the small motor 433 is started, the output shaft of the small motor 433 rotates, driving the lead screw 432 to rotate, causing the sliding block 434 to drive the round rod 435 to move, adjusting its distance from the center of the turntable 431.

[0037] Simultaneously, the rotary motor 41 is started. The output end of the rotary motor 41 rotates, causing the rotating shaft 42 to drive the turntable 431 to rotate, which in turn drives the round rod 435 to rotate. Then, under the action of the limiting member 437 and the positioning member 44, the vertical rod 438 is driven to move up and down stably, which in turn drives the fixed cylinder 51 to descend, which in turn drives the pressing body 55 to press the chest of the human body. At this time, the pressing rod 54 moves upward, which drives the pad 52 to compress the compression spring 53. By adjusting the lifting distance of the vertical rod 438, the lowering distance of the fixed cylinder 51 can be adjusted, so that the compression distance of the compression spring 53 can be adjusted. According to the compression amount and elastic coefficient of the compression spring 53, the force of the pressing body 55 pressing the patient's chest can be controlled, and the force gradually increases, further reducing the probability of chest fracture.

[0038] At the same time, when the pressure rod 54 compresses and tightens the spring 53, it can drive the guide rod 59 to slide in the limiting groove 561, thereby allowing the roller 57 to open to both sides and roll and press on both sides of the patient's chest, further improving the quality of chest compressions and further improving the stability of the patient when performing chest compressions.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
