Description

Technical Field

[0001] The invention relates to the field of emergency medical rescue, in particular to a cardiopulmonary resuscitation device for emergency medical rescue. Background Art

[0002] Cardiac arrest refers to the sudden cessation of heart beating due to various reasons in unexpected circumstances and time, which leads to the sudden cessation of effective cardiac pump function and effective circulation, causing severe ischemia, hypoxia and metabolic disorders of tissue cells throughout the body. If not rescued in time, life can be lost immediately. At present, the treatment method for cardiac arrest is mostly based on cardiopulmonary resuscitation. During cardiopulmonary resuscitation, the compression depth is at least 5 cm, and after each set of compressions, the patient needs to be supplied with oxygen to maintain the patient's vital signs. At present, cardiopulmonary resuscitation is mostly carried out by pressing the patient by hand for rescue; when medical staff perform rescue by hand, they consume a lot of physical energy, which will lead to insufficient compression force and depth in the later stage, thus affecting the rescue effect.

[0003] With the development of medical equipment in various departments, most cardiopulmonary resuscitation currently uses cardiopulmonary resuscitation devices. The various forms of cardiopulmonary resuscitation are divided into the following categories:

[0004] 1) Flatbed / bed-type cardiopulmonary resuscitation equipment, that is, a medical bed / flatbed is integrated with a cardiopulmonary resuscitation device, such as a medical care bed suitable for cardiopulmonary resuscitation disclosed in publication number CN106955214A. In this patent, the bed board in the device can be taken down and used as a stretcher to facilitate first aid for the patient, and the device can perform compression operations for cardiopulmonary resuscitation on the patient. The bed board is placed on the upper end of the rectangular frame, four handle seats are clamped on the rectangular frame, two bed legs are inserted into two bed leg sockets on the slide bar board, the slide bar hole is inserted into the slide bar, and the wheel fits the slide bar board, a bearing is inserted into the bearing groove, a connecting cylinder on the rotating bracket is inserted into the bearing on the bearing groove, and a fixed column is inserted into the fixed column slot, a cardiopulmonary resuscitation device frame is inserted into the upper end of the rotating bracket body through the rotating bracket socket, a hand-screw is pressed against the rectangular plate, two reciprocating rods on the cardiopulmonary resuscitation device, and an axis rod frame on a hand-cranked mechanism are connected to the cardiopulmonary resuscitation device frame body through screws, and the other end of the connecting rod on the hand-cranked mechanism is connected to the middle position of the top rod through a pin.

[0005] 2) Single-pressing resuscitation equipment, such as a chest-abdomen alternating compression cardiopulmonary resuscitation device disclosed in publication number CN103735402A. In this patent, the chest-abdomen alternating compression cardiopulmonary resuscitation device includes: a backboard, a support frame, left and right supports, and also includes two pressers for chest-abdomen alternating compression cardiopulmonary resuscitation. A telescopic mechanism for adjusting the distance between the two pressers is provided between the two pressers. The presser for pressing the chest is fixedly connected to the support frame. The upper ends of the left and right supports are hinged to the two ends of the support frame through hinges, and the lower ends of the left and right supports are fixed to the two ends of the backboard through a snap structure. The present invention belongs to the field of medical devices. The chest-abdomen alternating compression cardiopulmonary resuscitation device adds abdominal lifting and pressing functions, overcomes the existing resuscitation mode of single chest pressing of cardiac resuscitators, promotes the return of blood to the heart, increases the preload of the heart, and improves the success rate of rescue; alternating chest and abdomen compression helps blood flow to important organs, increases aortic pressure and central arterial pressure, and ensures blood supply and oxygen supply to important organs.

[0006] Although the above-mentioned cardiopulmonary resuscitation can be performed well, it still has some technical defects:

[0007] 1. Compared with the single-press type resuscitation device, the flatbed / bed type CPR device can perform resuscitation without the need for a medical bed. However, the CPR device disclosed in CN106955214A has a fixed bed board, which is not easy to adjust. In addition, the patient needs to be patted at a high frequency before CPR, which is impossible for this device to achieve.

[0008] 2. Compared with flatbed / bed-type cardiopulmonary resuscitation equipment, single-press resuscitation has the characteristics of small size and easy mobile installation, and can be used in emergency rooms, outdoors, etc. However, the cardiopulmonary resuscitation device disclosed in CN103735402A is also not equipped with the function of patting the patient to wake him up. In addition, the position of the presser of the device is limited, and it cannot be adjusted when encountering some obese patients.

[0009] Based on the defects of the above-mentioned flatbed / bed-type cardiopulmonary resuscitation equipment and single-press-type resuscitation equipment, the present invention proposes a cardiopulmonary resuscitation equipment for emergency medical rescue. The cardiopulmonary resuscitation equipment is improved based on the existing flatbed / bed-type cardiopulmonary resuscitation equipment, so that the height of the bed frame assembly can be adjusted, which is convenient for users to use; in addition, the equipment of the present invention can use the adsorption / repulsion force between high-frequency electromagnets and magnetic blocks to generate high-frequency vibrations in the early stage of cardiopulmonary resuscitation to achieve a patting wake-up function; at the same time, the pressing resuscitation unit provided in the present invention is integrated in the telescopic enclosure of the high-frequency patting unit and does not occupy space. In addition, the telescopic enclosure can also provide protection for the pressing resuscitation unit. Summary of the invention
