Technical Field

[0001] This utility model relates to the technical field of stretchers, specifically a warm and waterproof air transport stretcher. Background Technology

[0002] Air transport stretchers are key equipment used in medical rescue for the rapid transfer of the wounded / patients (especially in areas inaccessible by land transportation, such as mountainous areas, disaster areas, and offshore platforms). They need to meet core requirements such as lightweight, high strength, rapid fixation, and basic protection. For example, the patent announcement number CN222604833U provides a stretcher including a stretcher body, a neck fixation strap, a chest fixation strap, an abdominal fixation strap, a pelvic fixation strap, a limb fixation strap, and fixation rings. The stretcher body has a groove for placing a patient's body. The neck fixation strap, chest fixation strap, abdominal fixation strap, pelvic fixation strap, and limb fixation strap are respectively provided on both sides of the groove. Several fixation rings are provided at the bottom of the stretcher body, and these fixation rings can be connected to a transport vehicle via fixing ropes. This invention effectively secures the patient lying on the stretcher by providing neck, chest, abdominal, pelvic, and limb fixation straps, reducing the likelihood of movement. The fixing rings at the bottom of the stretcher, along with the fixing ropes, can secure the stretcher to the transport vehicle, improving the safety of patient transport.

[0003] However, existing air transport stretchers have fundamental deficiencies in the coordinated design of "waterproof" and "warmth retention", which makes it impossible for the device to simultaneously ensure the patient's body temperature is stable and the body is dry in complex environments. Especially in air transport scenarios, patients have lower tolerance for environmental changes, which seriously affects the continuous operating efficiency of the equipment. Therefore, in order to address the above-mentioned problems, there is an urgent need to innovate the design of existing air transport stretchers. Summary of the Invention

[0004] The purpose of this utility model is to provide a warm and waterproof air transport stretcher to solve the fundamental deficiency in the coordinated design of "waterproof" and "warm" in the current air transport stretchers mentioned in the background art. This results in the device being unable to simultaneously ensure the patient's body temperature is stable and the body is dry in complex environments. Especially in air transport scenarios, patients have lower tolerance to environmental changes, which seriously affects the continuous operating efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating and waterproof air transport stretcher, characterized in that it comprises: An integrated waterproof cover, and a multi-layer composite insulating pad fitted inside the integrated waterproof cover, with a waterproof zipper on the upper side of the integrated waterproof cover, a viewing window on the rear side of the waterproof zipper, a first support column on the outer side of the integrated waterproof cover, a first connecting buckle on the inner side of the first support column, a second support column connected to the left side of the first support column, a preset block inside the first support column, an extension rod connected to the inner side of the preset block, a limit ring in the middle of the extension rod, and an elastic locking component inside the second support column; The second anti-slip ring is attached to the outside of the limiting ring.

An anti-slip pad is attached to the outside of the end.

[0006] As a preferred embodiment of this utility model, the first support column and the second support column are rotatably connected, and the first connecting buckle is evenly spaced on the inner side of the first support column.

[0007] By adopting the above technical solution, the rotatable and foldable function of the first and second support columns makes it easy for operators to compress and store the device after use.

[0008] As a preferred technical solution of this utility model, the preset block and the extension rod are driven by a thread, and the limiting ring is rotatably connected to the extension rod.

[0009] By adopting the above technical solution, the extension length of the extension rod is locked by the limiting ring, which makes it easy to adjust the extension length of the device according to the usage needs of different personnel.

[0010] As a preferred embodiment of this utility model, the second anti-slip ring and the limiting ring are engaged and connected, and the longitudinal section of the second anti-slip ring is a circular structure.

[0011] By adopting the above technical solution, the extension rod is locked in place by the pre-tightening force generated by the second anti-slip ring in conjunction with the first anti-slip ring, thus preventing the extension rod from moving during use.

[0012] As a preferred embodiment of this utility model, the connecting ring and the extension rod are rotatably connected, and the extension plate provided on the inner side of the connecting ring is slidably connected to the first support column and the second support column.

[0013] By adopting the above technical solution, the extension plate is driven to extend outward from the inner side of the first support column and the second support column through the connecting ring, which makes it easy to adjust the extension length of the device according to the usage needs of different personnel.

[0014] As a preferred embodiment of this utility model, the second connecting buckle is evenly spaced in the middle of the extension plate, and the longitudinal section of the second connecting buckle is an arc-shaped structure.

[0015] Using the above technical solution, the movement of the connecting ring and the extension rod is guided by the extension plate in conjunction with the second connecting buckle. At the same time, the second connecting buckle set inside the extension plate can also provide more fixing points for the installation of the integrated waterproof cover.

[0016] As a preferred embodiment of this utility model, the connecting rod and the extension rod are threadedly connected, and the end is rotatably connected to the extension rod.

[0017] By adopting the above technical solution, the anti-slip pad is fixed to the end of the extension rod through the connecting rod and the end head, so as to avoid the sticky rain and snow on the surface from affecting the grip of the device and improve the stability of the device.

[0018] As a preferred technical solution of this utility model, the elastic locking assembly includes a return spring installed inside the second support column, and a locking block is connected to the right side of the return spring. A guide block is provided on the inner side of the locking block, and a guide plate is connected to the inner side of the guide block. An operating block is installed on the upper side of the locking block. The locking block is engaged with the first support column, and the locking block and the guide block are slidably connected to the guide plate.

[0019] By adopting the above technical solution, the connection between the second support column and the first support column is locked by the locking block, so as to prevent the first support column and the second support column from bending during use.

[0020] The integrated waterproof cover is made of high-density polyurethane coated Oxford cloth, and the multi-layer composite thermal pad inside the integrated waterproof cover is a combination of aluminum foil composite non-woven fabric and hollow fiber cotton.

[0021] By adopting the above technical solution, the combination of an integrated waterproof cover and a multi-layer composite warming pad ensures that patients are not easily harmed by water seepage or heat loss inside the device.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This warm and waterproof air transport stretcher wraps the patient with an integrated polyurethane-coated Oxford cloth and an insulated inner liner, which can effectively ensure the patient's body temperature is stable and the body is dry even in complex environments, avoiding the device from losing temperature in air transport scenarios and preventing the continuous operation efficiency of the device from being affected. At the same time, a large number of quick-release structures are set inside the device, which allows the operator to quickly fold and store the device after use, minimizing the space occupied by the device, thereby reducing the transportation and use costs of the device and achieving better use results, as shown in the following details. 1. This utility model uses the reverse pre-tightening force generated by the limiting ring and the second anti-slip ring to lock and limit the extension rod, so that the operator can adjust the extension length of the device according to the usage needs of different personnel. At the same time, this telescopic structural design makes it easy for the operator to retract the extension rod after the device is used, thereby reducing the footprint of the device. 2. This utility model uses an integrated waterproof cover combined with a multi-layer composite heat-insulating pad to wrap and protect the patient placed inside, making it difficult for the heat radiation generated by the patient's body to dissipate rapidly to the outside of the device. At the same time, the integrated structural design makes it difficult for rain and snow on the outside of the device to enter the inside and stay on the patient's skin surface, further reducing heat consumption and making it easy for the device to continue to operate in low-temperature environments. 3. This utility model uses an operating block and a guide plate to move the locking block and the guide block to the left to compress the reset spring. This release of the leftward movement locks the first support column. At this time, due to the rotating connection structure between the first and second support columns, the operator can easily fold the first and second support columns inward to compress them. This makes it easy for the operator to effectively fold the device after use, further reducing the area occupied by the device and thus reducing the transportation cost of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please see Figure 1-5 The present invention provides the following technical solution: a warm and waterproof air transport stretcher, comprising: an integrated waterproof cover 1, a multi-layer composite warm pad 2, a waterproof zipper 3, a viewing window 4, a first support column 5, a first connecting buckle 6, a second support column 7, a return spring 8, a locking block 9, a guide block 10, a guide plate 11, an operating block 12, a drain outlet 13, a preset block 14, an extension rod 15, a first anti-slip ring 16, a limiting ring 17, a second anti-slip ring 18, a connecting ring 19, an extension plate 20, a second connecting buckle 21, an end 22, a connecting rod 23, and an anti-slip pad 24; As attached Figure 1 Appendix Figure 3 and attached Figure 5As shown, before the device is used, the extension rod 15, which passes through the first support column 5 and the second support column 7, is rotated to make the extension rod 15 rotate outward along the preset block 14. At this time, the outward rotation of the extension rod 15 causes the connecting ring 19 to move outward, which in turn causes the connecting ring 19 to move outward along its inner side. When it reaches the designated location, the limiting ring 17 set in the middle of the extension rod 15 is rotated in the opposite direction, causing the limiting ring 17 to move inward toward the first support column 5 and the second support column 7. At this time, the inward movement... The side-rotating limiting ring 17 pushes the second anti-slip ring 18 to contact the first anti-slip ring 16 that is attached to the outer side of the first support column 5 and the second support column 7. The reverse pre-tightening force generated by the limiting ring 17 and the second anti-slip ring 18 locks the extension rod 15, preventing the extension rod 15 from telescopic movement during use. This makes it easy for operators to adjust the extension length of the device according to the usage needs of different personnel. At the same time, this telescopic structural design makes it easy for operators to retract the extension rod 15 after use, thereby reducing the footprint of the device. Simultaneously, the first support column 5 and the second support column 7 are installed along the first connecting buckle 6 and the second connecting buckle 21 inside them on the left and right sides of the integrated waterproof cover 1 to form an air transport stretcher. At this time, by pulling the waterproof zipper 3 on the upper side of the integrated waterproof cover 1, the upper opening of the integrated waterproof cover 1 is opened, making it easier for medical staff to place the patient inside the integrated waterproof cover 1. At the same time, pulling the waterproof zipper 3 in the opposite direction closes the upper opening of the integrated waterproof cover 1. At this time, the multi-layer composite warming pad 2 attached inside the integrated waterproof cover 1 can effectively reflect the heat radiation generated by the human body due to its material structure, preventing the patient placed inside the integrated waterproof cover 1 from losing body temperature rapidly. At the same time, the integrated waterproof cover 1 can ensure that rain and snow from the outside of the device cannot easily enter its interior, assisting the patient. The waterproof zipper 3 is placed on the skin surface to further reduce heat consumption. At this time, medical staff can observe the patient's condition lying inside the integrated waterproof cover 1 in real time through the viewing window 4 set on the back of the waterproof zipper 3. This avoids the inability of medical staff to provide timely rescue in case of an accident. At the same time, the end 22 is placed at the end of the extension rod 15. When the end 22 is rotated, the threaded connection structure between the connecting rod 23 and the extension rod 15 allows the end 22 to be effectively fixed at the end of the extension rod 15 during the rotation process. This makes it easy for the operator to grasp the anti-slip pad 24 attached to the outside of the end 22 to lift the device and the patient to move in the designated direction. At this time, due to the anti-slip material properties of the anti-slip pad 24, the rain and snow sticking to the surface of the anti-slip pad 24 are prevented from affecting the grip of the device, thus improving the stability of the device.

[0026] As attached Figure 1 Appendix Figure 2 and attached Figure 4As shown, after the device is used, the first support column 5 and the second support column 7 are removed outwards. At this time, the operating block 12 is pulled to the left, causing the operating block 12 to move the locking block 9 connected to its lower end to the left, compressing the return spring 8. Due to the sliding connection structure between the locking block 9, the guide block 10, and the guide plate 11, the locking block 9, which moves to the left, is guided and limited by the guide plate 11 and the guide block 10, preventing the locking block 9 from shifting its position during movement. At the same time, the drain outlet 13 at the lower end of the locking block 9 can effectively drain the rainwater trapped inside the return spring 8. Water is drained to prevent prolonged retention of rainwater from affecting the rebound stability of the return spring 8. Due to the locking connection structure between the locking block 9 and the first support column 5, the locking block 9, which moves to the left, releases its locking on the first support column 5. At this time, due to the rotating connection structure between the first support column 5 and the second support column 7, the operator can easily fold the first support column 5 and the second support column 7 inward to compress them. This facilitates effective folding of the device after use, further reducing the area occupied by the device and thus reducing the transportation cost of the device.

[0027] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
