Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically designs an automatic abdominal pressure lifting cardiopulmonary resuscitation device. Background Art

[0002] Active abdominal compression-decompression CPR [AACD-CPR] is a technique that stems from the limitation of traditional chest compression CPR for cardiac arrest. In addition, about 30% to 80% of patients will suffer from rib or sternum fractures and separation of the bone-cartilage junction, which will lead to damage to the lung, pleura and heart. This limits the implementation of traditional chest compression techniques and affects the success rate of CPR. Therefore, a new approach of "abdominal approach when chest is blocked" was explored, which is abdominal compression CPR. Abdominal compression CPR is a technique for patients with cardiac arrest that changes the pressure inside and outside the chest and abdomen by lifting and pressing the abdomen, exerting the "abdominal pump" mechanism, and then establishing a CPR that emphasizes both artificial circulation and breathing. How do we save the lives of patients with cardiac arrest in clinical practice? It is a cardiopulmonary resuscitation device that uses abdominal lifting and pressure. Its suction cup is attached to the upper and middle abdomen of a cardiac arrest patient. The rescuer holds the handle and actively pulls and presses the abdomen to change the intra-abdominal pressure, driving the diaphragm between the chest and abdomen to move up and down to create an "abdominal pump" mechanism, which in turn changes the volume of the chest cavity and the pressure gradient inside and outside the chest cavity, exerting the multi-pump effect of "chest pump", "heart pump" and "lung pump", increasing cardiac output while completing extracorporeal abdominal respiration, thereby realizing cardiopulmonary resuscitation technology that combines artificial circulation and breathing.

[0003] However, the abdominal lifting and compression cardiopulmonary resuscitation devices currently on the market are generally manually operated. When long-term operation is required, multiple people are required to assist on site. In the case of busy hospitals, this is a waste of manpower and time. If the abdominal lifting and compression cardiopulmonary device can automatically perform the lifting work, only one medical staff member is needed to observe the operation. Such a solution is provided by the utility model CN215915632U and the invention CN215875493U, but it was later discovered that the automatic abdominal lifting and compression cardiopulmonary devices disclosed in these two patents are all integrated. The integrated equipment takes up space and is troublesome to carry when in use. If the vehicle cannot reach the patient's location for various reasons when going out for emergency treatment, and can only be carried by medical staff, the difficulty in carrying the device will hinder the rescue time and consume the medical staff's excess physical strength, resulting in rescue delays or failures. Secondly, the integrated device is also inconvenient to maintain.

[0004] In summary, the abdominal lifting and compression cardiopulmonary devices currently on the market have the above problems, so an automatic abdominal lifting and compression cardiopulmonary device is designed. Utility Model Content

[0033] The biggest disadvantage of the abdominal compression cardiopulmonary device currently on the market is that it requires human operation and multiple people to assist, which is very troublesome. The utility model can realize the automation of the abdominal compression cardiopulmonary device, and the process is as follows: turn on the power of the compression device 1, and control the operation of the compression device 1 through the instrument button 103. After the control is issued, the signal is sent to the compression head 5 through the telescopic rod 6 and the electric contact 501 on the pressure lifting head 5, so that the telescopic rod 6 starts to extend and retract, and the negative pressure chamber 502 under the pressure lifting head 5 starts to work, and the patient is given abdominal compression cardiopulmonary resuscitation treatment. The instrument display screen 104 is used as an auxiliary to help medical personnel observe the operation of the machine. If a special situation is encountered, such as rescue outside, the terrain is uneven, and the wounded cannot be immediately transferred to a flat area, and the entire machine cannot rescue the patient, the button of the buckle 102 on the compression device 1 can be pressed to remove the compression device 1 as a whole and manually rescue the patient.

[0034] When this type of automatic abdominal lifting and compression cardiopulmonary resuscitation device is disclosed, such as the utility model CN215915632U and the invention CN215875493U, since it is an integrated machine, it is not easy to put away after use, and it is troublesome to carry when in use. If the vehicle cannot reach the patient's location due to various reasons during emergency treatment outside, and the medical staff can only carry it, the difficulty in carrying the device will hinder the rescue time and consume the medical staff's excess physical strength, resulting in rescue delays or failures. Secondly, the integrated device is also inconvenient to maintain. This situation will not occur in the present invention. When it is necessary to carry it out or store it when not in use, you can press the button of the buckle 102 on the lifting and pressing device 1 to remove the lifting and pressing device 1 as a whole, and then rotate the fixing ring 201 on the instrument bracket 2 to adjust it from the horizontal state to the vertical state, and then push the rotatable push rod 306 at the head of the support frame 3, push it out a certain distance, and then lock the tenon 305 to leave the slot. At this time, rotate the rotatable push rod 306 ninety degrees, release your hand, and the spring above the latch 304 will bounce upwards due to the lack of pressure. Above the spring is a stopper for the rotatable push rod 306, and below is a stopper for the slot, and the rotatable push rod 306 The push rod 306 is connected to the latch 304, so when the spring bounces upward, the latch is pushed to a position away from the ratchet 202. At this time, the instrument bracket 2 is rotated clockwise, and after rotating 270°, it merges with the support frame 3, so that the support frame 3 and the instrument bracket 2 are folded. When the base is connected to the base 4, it needs to be disassembled. Hold the handle of the support frame and push the push rod 307 with your thumb. The push rod hits the bottom of the connection hole of the base 4. The reaction force pushes the latch 310 out of the base 4 to complete the disassembly. The lifting head 5 can be removed from the telescopic rod 6 after rotation, and the entire disassembly is completed. Although the description is long, the actual disassembly time is less than one minute.
