[0002] The emergency stretcher is the core equipment for transporting patients during medical emergency, especially in the emergency scene of critical conditions such as cardiac arrest, it is necessary to carry out emergency operations such as cardiac compression during transportation.

[0003] For example, a rescue vehicle with cardiopulmonary resuscitation auxiliary function disclosed in CN221691666U includes a vehicle body frame and a table surface for carrying patients. The vehicle body frame is provided with moving wheels to facilitate the transportation of patients. One end of the vehicle body frame is connected to a turnover mechanism, and a cardiopulmonary resuscitation machine is connected to the turnover mechanism. The turnover mechanism can make the cardiopulmonary resuscitation machine in a first position or a second position. In the first position, the cardiopulmonary resuscitation machine is located below the table surface and does not block the patient from being lifted onto the table surface. In the second position, the cardiopulmonary resuscitation machine is located above the table surface and corresponds to the patient's heart and lung compression position. When in use, the rescuer lifts the patient onto the emergency stretcher, quickly moves the turnover mechanism, and makes the cardiopulmonary resuscitation machine in the first position move to the second position. Starting the power supply of the cardiopulmonary resuscitation machine can perform regular and uninterrupted cardiac compression, which can greatly save the installation time of the cardiopulmonary resuscitation machine, does not need to move the patient, can reduce the secondary accidents, and can save the rescue time for the patient. However, the emergency vehicle with cardiopulmonary resuscitation auxiliary function lacks limitation on the patient's body when using the cardiopulmonary resuscitation machine to perform cardiopulmonary resuscitation on the patient. The jolt and vibration during the driving of the emergency vehicle, combined with the high-frequency and high-intensity pressing action of the cardiopulmonary resuscitation machine, can easily cause the patient's body to shift, making it difficult to ensure the stability of the patient's body position. Not only can it cause the compression position to deviate and the depth to be out of control, but also can cause airway obstruction and other secondary risks, which seriously affect the emergency effect.

The first movable frame 16 is threadedly connected to the left side of the lead screw 9. The first movable frame 16 is slidably connected to the second connecting plate 4. The first movable frame 16 is located between the top plate 11 and the guide plate 12.

[0032] Using the blocking component of this device, the patient can be blocked after being raised. While rotating the lead screw 9, the first moving frame 16 is driven to move to the right, so that the first moving frame 16 presses the guide plate 12 to move to the right. Through the force of the second spring 13, the top plate 11 moves to the right and contacts the patient's feet, thereby blocking the patient and preventing the patient's body from sliding down after being raised. The second guide column 14 guides the top plate 11. The second spring 13 and the third spring 15 allow the position of the top plate 11 to be adjusted to accommodate patients of different body types.

[0033] like Figure 2 As shown, it also includes a weighing device 25. The weighing device 25 is connected to the upper side of the middle part of the first connecting plate 3. The presser 24, the weighing device 25 and the processor are electrically connected through the control module. The weighing device 25 is located between the guide side plates 17.
