Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a cardiopulmonary resuscitation pressing device for emergency critical care in coordination with ECMO catheterization for cardiac arrest. Background Art

[0002] Emergency critical illness usually refers to the patient's organ failure, including the "six failures"; the more organs that fail, the more serious the condition (more than two are called "multiple organ failure"), and the most serious situation is cardiac arrest, which requires extracorporeal life support (extracorporeal life resuscitation, VA-ECMO for cardiac arrest patients, and treatment). During this rescue process, one group of people needs to perform cardiopulmonary resuscitation and another group needs to perform ECMO catheterization. During the catheterization process, it is also necessary to interrupt and start compressions according to the requirements of the ECMO operator. It is a human resource intensive technology.

[0003] At present, after the manual mechanical compression device is installed on the patient's body, due to the different tightness of the straps, the compression device may not be able to effectively provide compression depth and arterial perfusion, resulting in poor neurological prognosis of the patient. When the compression quality is low, more than two nurses are required to adjust the tightness of the compression device, which increases the compression interruption time, thereby increasing communication costs and human resource consumption, and further reducing the ECPR survival rate. For this reason, we propose a cardiopulmonary resuscitation compression device for emergency critical care with coordinated cardiac arrest ECMO catheterization. Summary of the invention

[0031] Embodiment 2: Figure 4 As shown, this is a further description of Example 1. In this embodiment, the retracting mechanism 19 includes an installation box 20. The inner wall of the installation box 20 is provided with sound insulation cotton to reduce noise. The outside of the installation box 20 is fixedly connected with a frequency converter 41. The frequency converter 41 is a prior art and is convenient for adjusting the retracting mechanism 19. The installation box 20 is fixedly installed on the top of one of the brackets 2. The interior of the installation box 20 is symmetrically fixedly connected with shock-absorbing springs 32. The two shock-absorbing springs 32 are fixedly connected with dampers 31. The tops of the two dampers 31 are fixedly connected with arc blocks 30. The tops of the two arc blocks 30 are fixedly connected with motors 21. The arc blocks 30 are in contact with the outer wall of the motor 21. The motor 21 provides a power source for the retracting mechanism 19. The shock-absorbing springs 32 cooperate with the dampers 31 to effectively reduce the vibration of the motor 21, which is convenient for achieving a shock-absorbing effect on the retracting mechanism 19.

[0032] Specifically, see Figure 1 The output end of the motor 21 passes through the mounting box 20 and is fixedly connected with a rotating shaft 25. The outside of the rotating shaft 25 is provided with a thread, which can play an anti-slip effect. The rotating shaft 25 passes through and is rotatably connected to one of the brackets 2. The outside of the rotating shaft 25 is fixedly connected to the strap 17. At the same time, an opening is provided in the middle to facilitate the fixation of the strap 17. A rolling sleeve is provided on the outside of the rotating shaft 25 (not shown in the figure), and part of the strap 17 is located inside the rolling sleeve and is in a curled state.

[0033] Furthermore, the output end of the motor 21 is fixedly connected to a driving wheel 22, which is rotatably connected to the outside of one of the brackets 2, and the outside of the other bracket 2 is rotatably connected to a driven wheel 23, and the outside of the driving wheel 22 is rotatably connected to a belt 24, and the other end of the belt 24 passes through the inclined plate 1 and is rotatably connected to the driven wheel 23. Through holes are provided on the two side walls of the inclined plate 1 to facilitate the belt 24 to pass through, and the two brackets 2 are fixedly connected to the side close to the inclined plate 1 with support rods 26, and the insides of the two support rods 26 are rotatably connected to rotating rods 27, and the outsides of the two rotating rods 27 are The two rollers 28 are fixedly connected to each other, and the support rod 26 is used to connect the rollers 28. The rollers 28 play a turning role and cooperate with the adjusting piece 29 to make the strap 17 have a buffer process. The outsides of the two rollers 28 are rotatably connected to the strap 17. The motor 21 rotates the driving wheel 22, and then drives the driven wheel 23 to rotate through the belt 24. At the same time, the two shafts 25 are driven to rotate at the same time. At the same time, the rollers 28 rotate, and then drive the strap 17 to contract. The driving wheel 22 and the driven wheel 23 cooperate with each other, so that one motor 21 is used to achieve a linkage effect.

[0034] For further information, see Figure 2 and Figure 4The adjusting member 29 includes a return spring 37, which has an elastic effect, so that the return spring 37 is symmetrically fixedly connected to the bottom of the arc plate 4, and the bottom of the two return springs 37 is fixedly connected with a silicone pad 38, which is elastic. The bottom of the two silicone pads 38 is fixedly connected with a sensor 39. The specific model of the sensor 39 is selected according to the actual situation. The sensor 39 can prevent the contraction from being too tight, and can cooperate with the ultrasonic blood flow patch 34 to facilitate the cooperation of the contraction mechanism 19, so as to achieve the effect of automatic contraction. This device not only greatly reduces the interruption time of compression, reduces the communication cost and the human resource consumption of rescue, but also can greatly improve the quality of compression. When the compression quality is low, feedback is given immediately. There is no need for more than two nurses to adjust the tightness of the compression mechanism, but the strap 17 is tightened by the contraction mechanism 19, and the speed of the motor 21 is adjusted by the inverter 41. The adjustment member 29 can prevent the contraction from being too tight, which is convenient for protecting the patient, and then the self-feedback real-time adjustment is made through the self-contained carotid artery ultrasonic patch, which is expected to greatly improve the existing ECPR treatment survival rate.

[0035] To sum up, when using this device, first place the inclined plate 1, connect the connecting line 33 with the ultrasonic blood flow patch 34, let the patient lie on the inclined plate 1, then place the arc plate 4 above the patient's body, and stick the ultrasonic blood flow patch 34 on the patient's neck. At the same time, unfold the cushion 36 flatly to contact the patient, then press the movable rod 7 to connect the fixed hook 8 with the fixed ring 12, then reset the movable rod 7, rotate the rotating plate 10, and make it vertical with the connecting rod 14 and the rotating plate 10, so as to strengthen the fixed hook 8. At the same time, start the motor 21, and the frequency converter 41 cooperates to adjust the speed of the motor 21. The motor 21 rotates the driving wheel 22 to rotate, and then drives the driven wheel 23 to rotate through the belt 24. At the same time, it drives the two rotating wheels. The shaft 25 rotates at the same time, and at the same time, the roller 28 rotates, thereby driving the strap 17 to contract. At the same time, the motor 21 reduces noise and vibration with the cooperation of the damping 31 and the shock-absorbing spring 32. At the same time, the silicone pad 38 and the sensor 39 are in contact with the patient, and the reset spring 37 cooperates with the flexible pad 18 to play a buffering role to prevent excessive contraction, and the pressing mechanism 3 is started to press the patient. During the ECMO catheter placement process, the operator can interrupt and start pressing at any time according to his own requirements through the remote control 40, tighten the strap 17 through the contraction mechanism 19, and then adjust it in real time through the self-feedback of the built-in ultrasonic blood flow patch 34, so as to avoid extra waste of human resources and the time interval in between, avoid unnecessary interruptions of pressing, and shorten the interruption time of pressing.
