Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an emergency oxygen supply device and method which is convenient for transportation. Background Art

[0002] In various emergencies and emergency medical situations, such as traffic accidents, natural disasters or sudden illnesses, patients often need rapid and effective oxygen supply to maintain vital signs. Traditional oxygen delivery devices are often bulky and complex to operate, and are easily damaged or affect the oxygen delivery effect during transportation, which greatly limits the flexibility and efficiency of emergency work. In order to solve this problem, emergency oxygen delivery devices that are easy to transport came into being. The original intention of the design of this type of device is to reduce the size as much as possible, simplify the operation, and enhance its portability and durability while ensuring the oxygen delivery effect.

[0003] During the transportation of the oxygen supply device, it is crucial to fix and transport the oxygen supply device in different scenarios to ensure stability. Most of the existing oxygen supply devices are equipped with four sets of universal wheels, and oxygen supply mechanisms such as oxygen cylinders are placed vertically for transportation during transportation. It is difficult to control the balance when encountering uneven outdoor roads, and it is easy to tilt forward, causing damage to the oxygen cylinder, thereby affecting the efficiency of first aid. In addition, the oxygen supply device lacks a fixing mechanism in transportation scenarios such as transfer vehicles, and the oxygen cylinder is easy to shake in the vehicle. If the transfer rack is laid down, it will take up too much space and is not easy to transport. Summary of the invention

[0030] Embodiment 1: See also Figure 1-Figure 3In order to reduce the risk of damage to the oxygen supply device 3, this embodiment proposes an emergency oxygen supply device that is convenient for transportation, including a transportation mechanism 2 and an oxygen supply mechanism 3. The oxygen supply mechanism 3 is an oxygen cylinder and an oxygen mask connected to the oxygen cylinder. The transportation mechanism 2 includes a frame 21. One end of the frame 21 is connected to a cart handle 22, and the other end is folded upward to form a base 29. The base 29 is provided with wheels 28. The wheels 28 are arranged at the corners of the frame 21 and the bottom plate 29. In addition, the wheels 28 of this embodiment use large-size shock-absorbing tires, which greatly improves the safety of the patient. The transportation stability on uneven roads is improved; two sets of folding legs 24 are also connected to the bottom of the frame 21, and the folding legs 24 can provide support when the frame 21 is tilted; compression belts 210 are also connected to both sides of the frame 21, and a fixed space is formed between the compression belt 210, the frame 21 and the base 29, and the oxygen supply mechanism 3 is arranged in the fixed space to complete the fixation; in this embodiment, the compression belt 210 adopts a snap-on adjustable elastic belt, which can be adjusted according to oxygen supply mechanisms of different sizes to ensure the stability of the fixation of the oxygen supply mechanism.

[0031] In this embodiment, the folding leg 24 can adopt a conventional structure on the market, or can adopt the following structure, including: a boss 219 is connected to the bottom of the frame 21, the folding leg 24 is hinged on the boss 219, a limiting groove 211 is opened on the side of the folding leg 24 opposite to the frame 21, and a first limiting hole 25 is also opened on the folding leg 24, the first limiting hole 25 vertically passes through the limiting groove 211, and one end of the limiting hole is connected to the first fixing nut 217; a limiting rod 26 is provided at the bottom of the boss 219, one end of the limiting rod 26 is hinged on the frame 21, and the other end of the limiting rod 26 is opened. The end of the limiting rod 26 can extend into the limiting groove 211 to align the first limiting hole 25 with the second limiting hole 212, and the limiting bolt 27 can pass through the first limiting hole 25 and the second limiting hole 212 and be connected to the second fixing nut 218.

[0032] At the same time, a third limiting hole 214 is opened at the other end of the folding leg 24 hinged to the boss 219, and a limiting plate 215 is connected to the corresponding frame 21. A fourth limiting hole 216 is opened on the limiting plate 215, and one end of the fourth limiting hole 216 is connected to the first fixing nut 217. The limiting bolt 27 can pass through the third limiting hole 214 and the fourth limiting hole 216 to fix the end of the folding leg 24 on the frame 21. When the folding leg 24 is stored, the folding leg 24 is folded up, and the fixing bolt is passed through the third limiting hole 214 and the fourth limiting hole 216 to connect with the first fixing nut 217, so as to fix the folding leg 24 on the frame 21; when the folding leg 24 is supported, the fixing nut is removed, and the folding leg 24 and the limiting rod 26 are opened at the same time, and the end of the limiting rod 26 is extended into the limiting groove 211, and the second limiting hole 212 and the first limiting hole 25 are aligned, and the fixing bolt is passed through the first limiting hole 25 and the second limiting hole 212 in turn to connect with the second fixing nut 218 to form a triangular stable structure to achieve support.

[0033] In this embodiment, in order to facilitate the alignment of the first limiting hole 25 on the limiting rod 26 with the second limiting hole 212 , the bottom of the limiting rod 26 is flush with the end of the limiting groove 211 so that the limiting rod 26 is placed at the end of the limiting groove 211 .

[0034] The width of the limit rod 26 is the same as the distance from the inner side of the folding leg 24 to the frame 21 when the folding leg 24 is connected to the limit plate 215. This arrangement can ensure that the folding leg 24 can clamp the limit rod 26 when folded and stored, and there is no need to set an additional fixing mechanism for the limit rod 26.

[0035] Embodiment 2: See also Figure 1-Figure 8 In order to facilitate the fixing of the transfer mechanism 2 on the transfer vehicle to reduce bumps, based on the first embodiment, the device further includes a fixing mechanism 1 arranged on the side wall 4 of the transfer vehicle. The appearance of the transfer vehicle is as follows: Figure 8 As shown, the fixing mechanism 1 can be engaged with the transfer mechanism 2 so that the transfer mechanism 2 is fixed on the side wall 4 of the transfer vehicle.

[0036] The fixing mechanism 1 in this embodiment includes a fixing plate 14, which is fixed on the side wall 4 of the transfer vehicle. The fixing plate 14 is connected to a fixing block 11, and vertical guide grooves 12 are provided on both sides of the fixing block 11; an accommodating cavity is provided inside the fixing block 11, and a sliding plate 19 is provided in the accommodating cavity. Guide rods 13 are provided on both sides of the sliding plate 19, and the guide rods 13 extend out of the fixing block 11 and can slide vertically along the guide grooves 12; the top of the sliding plate 19 is connected to one end of a compression spring 18, and the other end of the compression spring 18 is fixed to the top of the fixing block 11; the bottom of the sliding plate 19 is connected to a clamping block 17, and the bottom of the clamping block 17 extends out of the fixing block 11; a clamping groove 23 is provided on the cart handle 22 of the transfer mechanism 2, and the clamping block 17 can extend into the clamping block 17 to fix the transfer mechanism 2 on the fixing plate 14.

[0037] The trolley handle 22 of the transfer mechanism 2 extends toward the back of the frame 21 so that the end face of the trolley handle 22 and the outer side of the folding leg 24 are on the same plane. This arrangement can ensure that when the transfer mechanism 2 is fixed to the fixing mechanism 1, the trolley handle 22 and the folding leg 24 are both attached to the fixing plate 14.

[0038] In addition, in order to strengthen the fixation of the transfer mechanism 2, a fixing groove 15 is also connected to the bottom of the fixing plate 14. After the transfer mechanism 2 is clamped with the fixing mechanism 1, the fixing groove 15 can extend between the folding legs 24, and the clamping rod 16 can pass through the gap between the folding legs 24 and the frame 21 and connect with the fixing groove 15 to fix the transfer mechanism 2 to the bottom of the fixing mechanism 1.

[0039] For ease of use, the bottom of the clamping block 17 is beveled so that the handle 22 of the cart can push the clamping block 17 backwards to push the clamping block 17 upwards so that the clamping block 17 automatically falls into the clamping slot 23 .

[0040] Directions: After transporting the transfer mechanism 2 to the transfer vehicle, place the transfer mechanism 2 vertically, align the clamping block 17 and push the transfer mechanism 2 backward, so that the clamping block 17 is pushed upward and then clamped into the clamping slot 23 under the action of the compression spring 18, and then the clamping rod 16 is horizontally inserted between the two folding legs 24 and the fixing slot 15 to achieve simultaneous fixation of the upper and lower parts; when disassembling, it is only necessary to pull out the clamping rod 16 and then lift the guide rod 13 to achieve the separation of the transfer mechanism 2 from the side wall 4 of the transfer vehicle, and the oxygen supply mechanism can be transported to the emergency site.

[0041] Embodiment three: See also Figure 9-11 In order to facilitate the transfer mechanism 2 to cooperate with Fig.11In the use of the emergency stretcher, on the basis of the first embodiment, a U-shaped card plate 221 is set at the cart handle 22, and a vertical slide groove 222 is opened on the side of the U-shaped card plate 221. A fastening bolt 220 that can move along the vertical slide groove 222 is provided in the vertical slide groove 222. The fastening bolt 220 is fixed to the side of the cart handle 22, and a groove 223 is opened at the top of the cart handle 22 corresponding to the U-shaped card plate 221. When the U-shaped card plate 221 is not in use, the U-shaped card plate 221 can be clamped down in the groove 223 without affecting the cooperation between the transfer mechanism 2 and the fixing mechanism 1.

[0042] Embodiment 4: See also Figure 1-Figure 13 In this embodiment, other parts are the same as those in the first embodiment, except that: when the oxygen delivery device of the second embodiment is fixed on the transport vehicle, due to the lack of support at the front end of the base 29, a rotation torque will be generated with the wheel 28 as the rotation axis, so that the card slot 23 and the card block 17 are subjected to a large shear force, which reduces the service life of the oxygen delivery device. Therefore, in this embodiment, a support assembly is connected to the bottom of the base 29 of the frame 21, and the support assembly includes a rotating rod 224 that penetrates the base 29, and the rotating rod 224 is rotatably connected to the base 29, and both ends of the rotating rod 224 extend The base 29 is extended outward, and the two ends of the rotating rod 224 are respectively connected to the support rod 225. The middle part of the support rod 225 is bent so that the support rod 225 is tilted when supporting the ground; the top of the support rod 225 is connected to the counterweight rod 226, and the middle part of the counterweight rod 226 is provided with a magnetic block 228, which can be magnetically connected to the oxygen cylinder in the oxygen supply mechanism 3; the bottom of the support rod 225 is supported on the ground in the supporting state of the support rod 225; a clamping block 227 is also provided on the side of the base 29, and when the support rod 225 is in the storage state, the bottom of the support rod 225 is against the bottom of the clamping block 227.

[0043] How it works: In the transport state, that is, the natural state, due to the existence of the counterweight rod 226, the support rod 225 will be against the bottom of the block 227. At this time, the support rod 225 is arranged parallel to the base 29; when support is needed, the counterweight rod 226 is pulled upward to make the magnetic block 228 on the counterweight rod 226 adsorbed onto the oxygen cylinder. At this time, the support rod 225 is supported on the ground to form a support; the support rod 225 can be bent in the middle so that the support rod 225 can be supported on the oxygen cylinder to form a support.

[0044] Embodiment five: In this embodiment, based on the oxygen delivery device in the fourth embodiment, a method for transporting the oxygen delivery device is designed, comprising the following steps: S1. In the hospital, the oxygen supply device is fixed to the fixed space of the frame 21 and fixed by the compression belt 210, the oxygen supply device is placed at an angle as a whole, and the handle of the cart is pushed to transport the oxygen supply device; S2.

Fix the oxygen delivery device; stand up the oxygen delivery device, connect the frame 21 to the fixing mechanism 1 on the transport vehicle, press the cart handle 22 to push the card block 17 upward and fall into the card slot 23 under the action of the compression spring 18; use the card rod 16 to pass through the fixing slot 15 and the gap between the folding leg 24 and the frame 21 to fix the transport mechanism 2 to the fixing mechanism 1; S5. Transfer: Start the transfer vehicle and transport the oxygen supply device to the emergency location; S6. Close the support assembly; after the transport vehicle arrives at the location, lift the guide rod 13 and pull out the card rod 16 to release the frame 21, separate the counterweight rod 226 from the oxygen supply mechanism 3, the counterweight rod 226 rotates under its own weight, so that the support plate 225 is stuck to the bottom of the block 227; S7. Fix the oxygen supply device; open the folding legs 24; tilt and push the transport mechanism 2 and the oxygen supply mechanism 3 from the transport vehicle to the emergency position, remove the limit bolt 27, open the folding legs 24, extend the end of the limit rod 26 into the limit groove 211 so that the first limit hole 25 is aligned with the second limit hole 212, and the limit bolt 27 passes through the first limit hole 25 and the second limit hole 212 and connects with the second fixing nut 218; S8.
