Description

Technical Field

[0001] The invention relates to the technical field of cardio-cerebral-pulmonary resuscitation, in particular to a cardio-cerebral-pulmonary resuscitation rescue device for an emergency department. Background Art

[0002] During emergency CPR, medical staff are required to continuously press the patient's chest at a certain frequency and strength. This high-intensity repetitive pressing action will cause the medical staff's arms, shoulders and other muscle groups to bear a huge physical burden in a short period of time. When medical staff perform long-term CPR operations, they often find it difficult to maintain a stable pressing frequency and strength due to excessive physical exhaustion. Studies have shown that after performing traditional compression CPR for several minutes in a row, the medical staff's pressing force may fluctuate significantly, which has an adverse effect on the effect of CPR. Since the operator is prone to fatigue, compression interruptions may occur. Compression interruptions during CPR are very dangerous. Each interruption will reduce the blood perfusion of important organs such as the heart and brain. When the compression interruption time exceeds 10 seconds, the patient's blood circulation and oxygen supply will be significantly affected, thereby reducing the success rate of CPR.

[0003] Some existing cardiopulmonary resuscitation assist devices lack sufficient precise adjustment capabilities for different patients. The physical characteristics of different patients, especially the thickness of the chest cavity, are different. Traditional devices often cannot adapt well to such differences, which may lead to inaccurate compression positions or compression strength that does not achieve the optimal effect. For patients with thicker chest cavities, if the device cannot be properly adjusted, the compression force may not be effectively transmitted to the heart. For patients with thinner chest cavities, excessive compression may cause complications such as rib fractures.

[0004] During cardiopulmonary resuscitation, the patient's body needs to be effectively fixed to ensure the accuracy of the compression operation. Some existing devices have defects in fixing the patient's body. Some devices cannot fit the human chest structure well. During cardiopulmonary resuscitation, the patient's body is prone to sliding, which not only affects the effect of compression, but also may cause medical staff to constantly adjust the compression position during the operation, wasting precious rescue time.

[0005] In summary, in view of these problems existing in traditional cardiopulmonary resuscitation operations and some existing devices, there is an urgent need for a new emergency department cardiopulmonary resuscitation rescue device that can solve the problem of operator fatigue, has precise adjustment functions and good fixation effects.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The braking device of the present invention adopts a rotating design. Compared with the traditional pressing braking method, it greatly reduces the physical burden of the operator. In the traditional cardiopulmonary resuscitation pressing operation, the operator needs to continuously apply vertical pressing force, which will cause the arm muscles to fatigue quickly. The rotating pressing design of the present device changes the way the force acts, and the operator is more labor-saving when operating. This labor-saving operation method enables the operator to continue cardiopulmonary resuscitation operations and prolongs the endurance of the operation. In the emergency cardiopulmonary resuscitation process, it can ensure that the patient receives uninterrupted and continuous pressing, which is crucial to improving the success rate of cardiopulmonary resuscitation. In the long-term rescue process, the traditional pressing method may cause the pressing frequency and force to be unstable due to the fatigue of the operator, and the present device can effectively avoid this situation. The braking device adopts the principle of the pressing and rotating mechanism, which further optimizes the labor-saving operation. When the relevant components are rotated to drive the operation, through the specific structural design, the device does not require the operator to apply excessive force when realizing the cardiopulmonary resuscitation function. This principle is ergonomic, and the operator can easily operate according to the design requirements, which not only reduces physical exertion, but also ensures the accuracy and stability of the operation.

[0014] 2. The first arc plate in the support device can move up and down and be precisely fixed by a nut. Since the chest thickness of different patients varies, this adjustable design is of great significance. Medical staff can adjust the position of the first arc plate according to the actual thickness of the patient's chest, thereby ensuring that the position and force of the compression can accurately act on the patient's heart during cardiopulmonary resuscitation. This helps to improve the effectiveness of cardiopulmonary resuscitation and reduce the risk of complications such as rib fractures caused by improper compression, excessive or insufficient compression. It is suitable for patients of different body shapes such as children and adults, and improves the versatility of the device.

[0015] 3. The second curved plate in the fixing device adopts an arc-shaped design, which fits the human chest structure. During cardiopulmonary resuscitation, this design can effectively fix the patient's chest and prevent the patient's body from sliding. The third groove opened on the second curved plate fits the human heart area, which not only helps to improve the accuracy of fixation, but also can better cooperate with the braking device to ensure that the pressing operation acts accurately on the heart area, thereby improving the effect of cardiopulmonary resuscitation.

[0016] 4. The rebound clip in the fixing device realizes the automatic rebound function through the torsion spring shaft, and its inner wall is provided with threads, which can be clamped and fixed with the second threaded rod. This fixing method is convenient and fast, and has high stability and reliability. During the installation and disassembly process, the automatic rebound characteristic of the rebound clip makes the operation easier. At the same time, the connection firmness between the fixing device and the supporting device is further enhanced through the threaded clamping, ensuring the stable fixation of the patient's body during the cardiopulmonary resuscitation operation, and avoiding the operation accuracy of the cardiopulmonary resuscitation affected by the movement of the patient's body.

[0017] 5. A U-shaped groove is provided on one side of the top surface of the lying board of the supporting device. This design facilitates the patient to tilt his head back so that artificial respiration can be performed smoothly. During cardiopulmonary resuscitation, the effective coordination of cardiopulmonary compression and artificial respiration is one of the key factors to improve the success rate of patient resuscitation. The existence of the U-shaped groove enables the device to better meet the various operational requirements during cardiopulmonary resuscitation and improve the overall rescue efficiency.

[0018] To sum up, the supporting device, braking device and fixing device in the present invention work together. The supporting device provides a stable basic platform for cardiopulmonary resuscitation operation, the braking device realizes labor-saving and effective pressing operation, and the fixing device ensures the stability of the patient's body. This collaborative working mode makes the entire cardiopulmonary resuscitation rescue process more efficient and orderly. The functions of each component complement each other, which maximizes the success rate of cardiopulmonary resuscitation and provides a more ideal equipment solution for cardiopulmonary resuscitation rescue work in the emergency department.
