Description

Technical Field

[0001] This utility model relates to the technical field of rescue stretchers, and in particular to a rapid-inflation rescue stretcher. Background Technology

[0002] Emergency rescue generally refers to the activities and plans for prevention, preparation, response and recovery in response to sudden and destructive emergencies. Emergency events are prone to cause casualties. During rescue operations, it is necessary to evacuate the injured or those in need of rescue from the scene of the incident to avoid secondary injuries and more serious consequences, and to minimize losses.

[0003] Existing rescue stretchers, such as the portable rescue stretcher disclosed in utility model patent application number 202121343070.9, mainly include an inflatable airbag for the patient to lie flat, a first box installed at one end of the inflatable airbag to store the inflatable airbag, and a second box installed at the other end of the inflatable airbag to store the inflatable airbag. The inflatable airbag is equipped with an inflation port for inflation and a deflation port for deflation, and a sealing cap is connected to the deflation port. In use, the first box and the second box are first pulled apart, and the length of the pull apart is determined by the length of the telescopic rod. The inflatable airbag is inflated through the inflation port, which expands the inflatable airbag and allows the patient to lie flat comfortably.

[0004] However, most of the existing inflatable rescue stretchers use disposable gas cylinders. These cylinders cannot be reused, and each cylinder can only be filled once. The inflation volume cannot be adjusted according to changes in climate and environment, and the rigidity requirements cannot be met. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a quick-inflating rescue stretcher that can be repeatedly filled with gas, uses an aluminum cylinder as a gas source, is lightweight, has an adjustable gas cylinder valve, inflates the stretcher valve through a quick-connect one-way valve with a flexible air tube, and automatically closes the one-way valve after being fully inflated. The stretcher is equipped with a highly wear-resistant protective plate under it, allowing it to be dragged in harsh environments.

[0006] This utility model relates to a rapid inflatable rescue stretcher, which includes a stretcher, a fixing mechanism, a lifting mechanism, and an inflation mechanism. The fixing mechanism is installed on the stretcher to secure the patient, the lifting mechanism is installed on the stretcher to facilitate lifting, and the inflation mechanism is installed on the stretcher to inflate the air cushion. The operator connects the inflation mechanism to the stretcher, inflates the air cushion, places the patient on the stretcher, secures the patient with the fixing mechanism, and then lifts and transports the stretcher and the patient using the lifting mechanism.

[0007] Preferably, the stretcher includes a drag plate, an air cushion, four sets of handles, a safety valve, and a one-way valve. The air cushion is mounted on the drag plate, all four sets of handles are mounted on the air cushion, the safety valve is mounted on the air cushion, and the one-way valve is mounted on the air cushion. The drag plate facilitates dragging by staff and avoids friction damage to the air cushion. The inflation mechanism is connected to the one-way valve to inflate the air cushion, improving patient comfort. Staff can easily move the air cushion by operating the four sets of handles, and the safety valve allows for timely depressurization.

[0008] Preferably, the fixation mechanism includes a head fixation strap, two sets of waist fixation straps, and leg fixation straps. The head fixation strap is installed on the air cushion, both sets of waist fixation straps are installed on the air cushion, and the leg fixation straps are installed on the air cushion. The staff uses the head fixation strap, the two sets of waist fixation straps, and the leg fixation straps to fix the patient's head, waist, and feet respectively to prevent the patient from falling off the air cushion and to ensure the fixation effect on the patient.

[0009] Preferably, the lifting mechanism includes four sets of lifting buckles, four sets of lifting ropes, and a hook. The four sets of lifting buckles are all installed on the air cushion, and the four sets of lifting ropes are respectively tied to the four sets of lifting buckles. The hook is installed on the helicopter and connected to the four sets of lifting ropes. The hook at the bottom of the helicopter hooks the four sets of lifting ropes, and the air cushion is easily lifted by the four sets of lifting ropes and the four sets of lifting buckles, which facilitates rapid transfer.

[0010] Preferably, the inflation mechanism includes an air tank, a manual cylinder head valve, a connecting high-pressure hose, and a quick-connect fitting. The manual cylinder head valve is installed on the air tank, the connecting high-pressure hose is installed on the manual cylinder head valve, and the quick-connect fitting is installed on the connecting high-pressure hose. When inflation is required, the operator inserts the quick-connect fitting into the one-way valve, adjusts the inflation volume through the manual cylinder head valve, and the compressed air in the air tank is delivered to the air cushion through the connecting high-pressure hose.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff connects the inflation mechanism to the stretcher, inflates the air cushion, then places the patient on the stretcher, the fixing mechanism fixes the patient, and the lifting mechanism lifts and transports the stretcher and the patient.
