[0060] The portable transport device for emergency oxygen cylinders according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0061] Reference Figures 1 to 6 As shown, the portable transport device for emergency oxygen cylinders provided according to an embodiment of the utility model includes a towing basket 10 , casters 20 and a rotating arm 30 .

[0062] Specifically, the trailer basket 10 is formed into a strip mesh basket structure adapted to the oxygen cylinder 50, and the trailer basket 10 is made of a light but high-strength metal or other material. It not only ensures sufficient structural strength, but also reduces its own weight burden. One end of the trailer basket 10 in the length direction is a closed end, and the other end of the trailer basket 10 in the length direction has a handle 1011 suitable for holding. One side of the trailer basket 10 in the width direction is open to form a loading chamber P10 for loading the oxygen cylinder 50. This laterally open loading chamber P10 is convenient for loading and unloading the oxygen cylinder 50. The closed end ensures that after the oxygen cylinder 50 is loaded into the loading chamber P10, the bottom of the oxygen cylinder 50 can be abutted against the closed end to position and fix the oxygen cylinder 50. The handle 1011 on the trailer basket 10 is convenient for the user to hold and then drag the trailer basket 10.

[0063] Casters 20 are provided at the bottom of the closed end so that the trailer basket 10 can be freely dragged and moved. The casters 20 can play a supporting and rolling role. The trailer basket 10 can be freely moved by using the casters 20, which is easy and labor-saving.

[0064] The rotating arm 30 is located on the side of the trailer basket 10 facing away from the loading chamber P10, and one end of the rotating arm is adjacent to the handle 1011 and is pivotally connected to the trailer basket 10, so that the rotating arm 30 can be pivoted between an open position and a folded position. For example, a cylindrical rod is provided at one end of the trailer basket 10 away from the caster 20, and a hollow tube is provided at one end of the rotating arm 30. The hollow tube is sleeved on the cylindrical rod, and the rotating arm 30 is rotated relative to the trailer basket 10 in turn. Exemplarily, the rotating arm 30 can be formed by combining a plurality of pipes, so that it can ensure strength and stability while also having a lighter weight.

[0065] When the rotating arm 30 is in the open position, a predetermined angle is formed between the rotating arm 30 and the trailer basket 10 to support the trailer basket 10 tilted on the ground; when the rotating arm 30 is in the folded position, the rotating arm 30 is attached to the side of the trailer basket 10 in the width direction facing away from the loading cavity P10.

[0066] When the device is in use, the rotating arm 30 can be pulled open by one hand to form a predetermined angle with the trailer basket 10. At this time, the entire device is supported on the ground in an inclined posture, and medical staff directly use the oxygen cylinder 50 to supply oxygen to the patient. After use, the rotating arm 30 can be pushed to automatically fit and store it on one side of the trailer basket 10, thereby restoring the overall portable form.

[0067] According to the portable transport device for emergency oxygen cylinders provided by the embodiment of the utility model, the strip mesh basket structure is used to not only reliably fix the oxygen cylinder 50, but also to minimize the overall weight. Combined with the casters 20, the device is easy to drag and has good mobility. Medical staff can push and pull the device at will and can move quickly in an emergency environment. In addition, the device also has the function of tilt support. The tilt state of the device can be easily switched by the rotating arm 30. When not in use, the rotating arm 30 can be completely attached to the side of the trailer basket 10, and will not take up additional space. It is easy to use, manage and carry. The transport device meets the requirements of the emergency environment for high efficiency, speed and convenience in transporting oxygen cylinders 50, greatly reduces the burden on medical staff, and improves the efficiency of emergency work.

[0068] Reference Figure 1 to Figure 2 and Figure 5 to Figure 6 As shown, in some embodiments of the utility model, the trailer basket 10 includes a bottom plate 104 and a basket body, the basket body includes a U-shaped tube 101, an arc tube and a bracket 103, the two arms of the U-shaped tube 101 extend downward, the arc tube 102 and the bracket 103 are arranged on the two arms of the U-shaped tube 101 at intervals along the length direction of the U-shaped tube 101, and define the loading cavity P10 between the U-shaped tube 101. The lower ends of the two arms of the U-shaped tube 101 and the lower end of the bracket 103 are fixed on the bottom plate 104.

[0069] In this embodiment, the interior of the basket body is formed into a loading cavity P10 by using a combination of a U-shaped tube 101, an arc tube and a bracket 103, so as to facilitate loading and unloading of oxygen cylinders 50. This structural design not only makes the entire basket 10 more portable and the structure more solid and reliable, but also the shape and size of the loading cavity P10 can meet the specifications of conventional medical oxygen cylinders.

[0070] Reference Figure 1 to Figure 2As shown, in one embodiment of the present invention, the caster 20 is located on the side of the bottom plate 104 away from the loading cavity P10. The upper end of the U-shaped tube 101 is bent toward the side away from the loading cavity P10 to form an inclined opening, which is communicated with the loading cavity P10, and the handle 1011 is formed at the upper end of the U-shaped tube 101.

[0071] When towing, the caster 20 can touch the ground by holding the upper end of the U-shaped tube 101, which is convenient for towing and moving. The upper end of the U-shaped tube 101 is bent, which is convenient for users to hold, and the inclined opening formed is convenient for loading or removing the oxygen cylinder 50. Through the optimized design of the above structure, the towing basket 10 is more convenient to use, and the user experience is improved.

[0072] Reference Figures 1 to 6 As shown, in some embodiments of the present invention, a limit frame 40 is provided at the upper end of the U-shaped tube 101. When the rotating arm 30 rotates to the open position, the limit frame 40 stops the rotating arm 30 to limit the rotating arm 30 to the open position.

[0073] When the device needs to be supported to form a tilted state, the operator only needs to gently push the rotating arm 30, and the rotating arm 30 can be opened to abut against the limit frame 40. In this way, a stable supporting posture can be obtained under the action of the limit frame 40. After use, the rotating arm 30 is automatically folded and abutted against the side.

[0074] In this embodiment, the design of the limit frame 40 realizes automatic positioning of the open position, while also improving the stability and safety of the support, avoiding the risks that may be caused by accidental shaking, and making the operation of the entire device safer and more reliable.

[0075] Reference Figures 2 to 3 As shown, in one embodiment of the present invention, the limit frame 40 includes a fixed arm 401, a telescopic rod 402 and a stop rod 403, and the fixed arm 401 is fixed to the upper end of the U-shaped tube 101. The fixed arm 401 can be a metal tube body, which is firmly connected to the upper end of the U-shaped tube 101 by welding or the like. The diameter of the fixed arm 401 is slightly larger than the telescopic rod 402, so that one end of the telescopic rod 402 can be slidably inserted into the interior of the fixed arm 401 to form a sliding fit relationship.

[0076] One end of the telescopic rod 402 is slidably connected to the fixed arm 401, and a multi-stage elastic positioning fastener is provided between the telescopic rod 402 and the fixed arm 401, so that the length of the telescopic rod 402 can be adjusted in multiple stages. The telescopic rod 402 is a rod, one end of which is slidably connected to the fixed arm 401 to form an adjustable structure that can be telescoped.

[0077] The stop rod 403 is connected to the other end of the telescopic rod 402, and when the rotating arm 30 rotates to the open position, the stop rod 403 abuts against the rotating arm 30. The stop rod 403 is a cross bar, which can be vertically connected to the telescopic rod 402 by welding or other methods. Preferably, there are two fixed arms 401 and two telescopic rods 402, and the two telescopic rods 402 correspond to the two fixed arms 401 one by one, and the stop rod 403 is connected between the two telescopic rods 402. When the rotating arm 30 is in the open state, the rotating arm 30 just abuts against the stop rod 403. After the length of the telescopic rod 402 is adjusted, the position of the stop rod 403 can be changed, thereby changing the limiting angle of the rotating arm 30, thereby realizing the angle adjustment of the rotating arm 30.

[0078] In order to adjust the length of the telescopic rod 402, a plurality of positioning holes H401 are provided on the outer surface of the fixed arm 401 at equal intervals along the axial direction, and a matching elastic fastener 404 is provided on the wall of the telescopic rod 402. By inserting the head of the spring buckle into different positioning holes H401, the extended length of the telescopic rod 402 can be adjusted and locked.

[0079] When the opening angle of the rotating arm 30 needs to be changed, the operator only needs to press the spring fastener lightly to disengage it from the original positioning hole H401, then slide the telescopic rod 402 axially to the desired length, and then release the spring fastener to lock it in the new position. The change in the length of the telescopic rod 402 will cause the stop rod 403 to change its position, thereby changing the limiting angle of the rotating arm 30.

[0080] The design of the adjustable limit frame 40 makes the device more applicable. According to different scenarios and needs, the rotating arm 30 can be flexibly adjusted to open to different angles, so that the device can obtain an ideal support state in various application environments, further improving the adaptability of the product.

[0081] Reference Figure 1 to Figure 2 As shown, in one embodiment of the present invention, an angle less than 90° is formed between the fixing arm 401 and the upper end of the U-shaped tube 101, and the fixing arm 401 is suitable for being hung on one side of the bed.

[0082] In some cases, if the device needs to be combined with a bed for use, it is only necessary to move the device to the side of the bed, rotate the rotating arm 30 to the folded position, and then hang the fixed arm 401 on the bed. In this way, the oxygen cylinder 50 can be hung on the side of the bed to facilitate oxygen supply. This design provides more ways of use and is more flexible and convenient to use.

[0083] Reference Figure 2As shown, in one embodiment of the present invention, a latch 1031 is provided on one side of the bracket 103 facing the rotating arm 30 , and when the rotating arm 30 is in the folded position, the latch 1031 is suitable for latching and fixing the rotating arm 30 .

[0084] That is, when the rotating arm 30 is in the folded state, the rotating arm 30 can be fastened to the snap-fitting part of the bracket 103, and the snap-fitting part 1031 can be used to firmly snap-fit ​​the rotating arm 30 to the side of the bracket 103. When the rotating arm 30 needs to be opened, the operator only needs to use a little force to move the rotating arm 30 so that the rotating arm 30 is separated from the snap-fitting part 1031, and the rotating arm 30 can be freely rotated to the open position.

[0085] The design of the buckle 1031 further enhances the stability of the rotating arm 30 in the folded state, and avoids the inconvenience caused by the accidental movement of the rotating arm 30 when not in use. In addition, the buckle mode of the buckle 1031 is convenient and simple to use.

[0086] Reference Figures 1 to 2 As shown, in some embodiments of the present invention, a hanging chain 105 is provided on one arm of the U-shaped tube 101, and a hook 106 is provided on the other arm of the U-shaped tube 101. The hanging chain 105 is suitable for bypassing the loading chamber P10 and then being hung on the hook 106 to constrain the oxygen cylinder 50 in the loading chamber P10.

[0087] When loading the oxygen cylinder 50, the oxygen cylinder 50 is first placed in the loading chamber P10 easily, and then the oxygen cylinder 50 is passed around from one side and one end of the hanging chain 105 is hung on the hook 106 on the opposite side. By adjusting the tightness of the hanging chain 105, the loaded oxygen cylinder 50 can be firmly restrained in the loading chamber P10.

[0088] The combination design of the hanging chain 105 and the hook 106 is adopted to form a simple and effective restraint mechanism. In addition, installation and disassembly are very convenient, and the medical staff can quickly connect or separate the free end of the hanging chain 105 and the hook 106.

[0089] Reference Figure 4 As shown, in one embodiment of the present invention, when the limiting frame 40 is retracted to the shortest state and the rotating arm 30 is in the folded position, the limiting frame 40 and the casters 20 can support the trailer basket 10 on the ground and keep it in a substantially horizontal state. In this way, when not in use, the entire device can be placed horizontally on the ground, which can reduce the occupied space, facilitate storage management, and ensure safety.
