Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of first aid equipment, and in particular relates to a cardiopulmonary resuscitation stretcher. Background Art
[0002] In the pre-hospital setting (120), patients with cardiac arrest (CA) are often encountered; CA may also occur when troops are performing tasks in special environments such as plateaus (mountains). CA is the most serious and urgent medical emergency.
[0003] For patients with out-of-hospital cardiac arrest (OHCA), cardiopulmonary resuscitation (CPR) is required on site. Once the resuscitation is successful, they must be immediately transferred to the hospital and continue to receive advanced life support treatment. CA may occur again at any time during the transfer and CPR must be performed immediately. Some require direct transportation to the hospital. The transportation method from the first scene to the ambulance varies greatly depending on the institution and region, and there is no consensus in our country.
[0004] When CA occurs in some old residential communities without elevators, the only way to transport the patient is to use the stairs. For CA patients, when medical staff carry them through the stairs, chest compressions may be temporarily interrupted due to the narrow stairs and insufficient medical staff, which reduces the quality of CPR. Statistics show that it takes an average of 1.8 minutes (1.1 minutes to 3.6 minutes) to carry a patient from the 3rd floor up the stairs to the 1st floor, and an average of 4.76 minutes (3.4 minutes to 5.8 minutes) to carry a patient from the 6th floor up the stairs to the 1st floor, far exceeding the time limit for compressions within the "golden 4 minutes". If chest compressions are not performed during this period, circulation will be interrupted for 4-6 minutes, and irreversible pathological changes and irreversible damage will occur, followed by the transition to biological death. This is more time-consuming and labor-intensive for heavier patients. In addition, according to the National Standard Residential Design Code (GB009-2011), the width of the elevator car shall not be less than 1.43 meters and the depth shall not be less than 1.25 meters. Only the minimum dimensions are specified. The current dimensions of the elevator cars in most residential communities do not meet the stretcher size requirements (2 meters × 0.6 meters). When a soft stretcher is used for emergency medical assistance to transport a patient into a narrow elevator, chest compressions will be interrupted, reducing the quality of CPR.
[0005] In addition, CA may occur when troops are performing tasks in special environments such as plateaus (mountains), and the wounded need to be urgently transferred down the mountain from the top of the mountain. If there is no professional equipment to continuously perform high-quality chest compressions during the transfer process, the best opportunity for treatment will be lost, resulting in irreversible consequences.
[0006] Moreover, when carrying a stretcher, it will be more inconvenient for the person carrying the front side of the stretcher to move, especially when carrying the stretcher on an inclined road, which will increase physical exertion. Utility Model Content

[0015] Furthermore, the slide blocks of the electric slide rails are respectively fixedly mounted with Hall effect rockers, the ends of the Hall effect rockers are respectively fixedly connected to the second internally threaded tubes, and the Hall effect rockers are respectively connected to the control switches of the corresponding electric slide rails through circuits.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. A cardiopulmonary resuscitation stretcher according to an example of the present invention. When using the device, the first extension rod and the second extension rod are laid flat, and the corresponding first internal threaded tube is rotated to connect the telescopic rod, the first extension rod and the second extension rod into one body. The telescopic rod is adjusted to extend or retract according to the patient's body shape, and the resuscitation machine base is placed on the telescopic rod. The resuscitation machine base is fixed with the first buckle and the anti-slip belt. The patient is then transferred to the bottom of the resuscitation machine base and the resuscitation machine is started. This allows the patient to be transported in different environments while being able to perform uninterrupted and continuous high-quality chest compressions. When encountering a narrow space, the first internal threaded tube corresponding to the second extension rod is rotated to remove the fixation between the second extension rod and the telescopic rod. The patient's lower limbs are flexed and the telescopic rod is pushed to shorten the stretcher. In this process, the continuous high-quality cardiopulmonary resuscitation of the upper body is not affected. Press, and after use, rotate the corresponding first internal threaded tube to fold the first extension rod and the second extension rod into a 90-degree angle, so that the stretcher frame forms a U-shaped box structure, and the resuscitation machine base and the resuscitation machine are stored in the box structure, so as to facilitate the protection and carrying of the resuscitation machine body. Through this device, the full-size or corresponding-size equipment can be unfolded according to the environmental conditions during use, thereby greatly saving the equipment assembly time and environmental requirements when transporting patients in different environments, and being able to perform uninterrupted and continuous high-quality chest compressions on patients during stretcher first aid, seize the best treatment time, and improve the patient's survival rate. It is also convenient for rescue personnel to operate and lift the stretcher during use, and after use, the device can be folded and placed, which is more portable and can protect the resuscitation machine body while carrying it.
[0018] 2. A cardiopulmonary resuscitation stretcher according to the present invention is used by passing the anti-slip belt around the telescopic rod, passing it through the buckle and tightening it, so that the resuscitation machine base can be fixed on the buckle.
[0019] 3. A cardiopulmonary resuscitation stretcher in the example of the present invention, after the device is folded and stored, the Velcro surface A is bonded to the Velcro surface B to form a pulling strap structure, which is convenient for the portable device to be carried as a whole.
[0020] 4. A cardiopulmonary resuscitation stretcher according to an example of the present invention can facilitate the movement of the trunk support plate, the head support plate and the lower limb support plate along the corresponding telescopic rod, the first extension rod and the second extension rod through the ring.
[0021] 5. A cardiopulmonary resuscitation stretcher according to an example of the present invention can conveniently fix the trunk support plate, the head support plate and the lower limb support plate to the corresponding telescopic rod, the first extension rod and the second extension rod by tightening the bolts.
[0022] 6. A cardiopulmonary resuscitation stretcher according to an example of the present invention, when in use, when one person is carrying the stretcher in front, the operator wears a vest, connects the two screws to the second internal threaded tube respectively and rotates the second internal threaded tube to connect. When two people are carrying the stretcher in front, the two people wear vests respectively and insert a screw into the second internal threaded tube respectively. By controlling the electric slide rail, the corresponding second internal threaded tube is driven to rise and fall, which can facilitate the adjustment of the height of the stretcher when carrying it, and reduce the patient's comfort caused by the stretcher tilting when carrying it on a sloping road.
[0023] 7. A cardiopulmonary resuscitation stretcher in the example of the present invention can drive the Hall rocker to shift when the stretcher tilts.
