[0002] With the continuous improvement of hospital medical technology and first-aid capacity, the treatment of critical patients is increased, and the use rate of pre-hospital advanced first-aid equipment is greatly increased. In the traditional transfer mode, due to the limited space of the stretcher, various equipment cannot be placed, including the oxygen cylinder for maintaining the smooth breathing of the patient. The oxygen cylinder and other equipment are usually placed in the gap of the stretcher or carried by medical staff, but this will occupy human resources, which is not conducive to the observation of the patient's condition by medical staff, nor is it conducive to the effective first-aid measures for the patient. The current medical staff need to control the oxygen cylinder portable vehicle while using the stretcher to transport the patient, so as to maintain the distance between the oxygen cylinder and the stretcher, and prevent the oxygen cylinder from tipping over during transportation. Once the oxygen cylinder tips over, it is easy to cause a fire. Therefore, the current oxygen cylinder portable vehicle consumes a lot of energy and physical strength of medical staff, affecting the safety of patients and equipment.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application are clearly and completely described below through specific specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the present application. The present application can also be implemented or applied through other different specific embodiments. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0026] An oxygen cylinder transfer device, such as Figures 1-5As shown, the device comprises: a connecting rod frame 1, the connecting rod frame 1 is connected with a first surrounding part 11 and a second surrounding part 12, the first surrounding part 11 and the second surrounding part 12 are coaxial, the second surrounding part 12 is provided with an intercepting piece 121, when an oxygen cylinder passes through the first surrounding part 11 and extends into the second surrounding part 12, the intercepting piece 121 limits the movement of the oxygen cylinder along its own axis; a hanging part 2, comprising a base plate 21 and a hook 22 connected with each other, the base plate 21 is connected with the connecting rod frame 1, and the hook 22 is linearly distributed on the outer wall of the base plate 21 away from the connecting rod frame 1; a fixing part 3, comprising a supporting leg 31 and an elastic piece 32, the supporting leg 31 is rotationally connected with the connecting rod frame 1, and the two ends of the elastic piece 32 are connected with the connecting rod frame 1 and the supporting leg 31 respectively, the supporting leg 31 can move to an initial position and a supporting position, and the supporting leg 31 has a movement trend towards the connecting rod frame 1 under the driving of the elastic piece 32 when the supporting leg 31 is away from the initial position. Specifically, when the connecting rod frame 1 is placed on a horizontal plane or a plane parallel to the horizontal plane, the movement plane crossed by the relative rotation between the supporting leg 31 and the connecting rod frame 1 coincides with the direction of gravity, that is, the rotation of the supporting leg 31 is towards or away from the direction of gravity in this state. The supporting leg 31 can also move to an equilibrium position, when the supporting leg 31 moves to the equilibrium position, the supporting leg 31 and the elastic piece 32 are in the same plane, at this time, the supporting leg 31 still has a trend of being pulled by the elastic piece 32 and moving towards the connecting rod frame 1, but the trend of the supporting leg 31 rotating to both sides of the axis is in a balanced state, when the supporting leg 31 is subjected to an external force away from or towards the direction of gravity in this state, the balance of the supporting leg 31 and the elastic piece 32 is broken and the supporting leg 31 approaches the connecting rod frame 1 away from the direction of gravity under the pulling of the elastic piece 32; or, the supporting leg 31 is pressed against the plane where the connecting rod frame 1 is located towards the direction of gravity under the pulling of the elastic piece 32, when the supporting leg 31 is pressed against the ground, the supporting leg 31 and the connecting rod frame 1 form stable support for the rotating device. When the supporting leg 31 is in the initial position, the elastic piece 32 does not deform; when the supporting leg 31 is in the supporting position, the end of the supporting leg 31 away from the connecting rod frame 1 is in contact with the ground and the supporting leg 31 is limited, the reason why the supporting leg 31 is limited is that the supporting section 141 of the fixed connecting rod 14 and the end of the supporting leg 31 away from the connecting rod frame 1 are pressed against the ground at the same time and the other end of the supporting leg 31 is pressed against the connecting rod frame 1, so that all the degrees of freedom of the supporting leg 31 are locked in this state.

[0027] In some embodiments of the present application, as Figures 1-5As shown, the connecting rod frame 1 comprises fixed connecting rods 14 and movable connecting rods 13, the first surrounding part 11 is connected with the movable connecting rod 13, the second surrounding part 12 is connected with the fixed connecting rod 14, the movable connecting rod 13 is coaxially and slidingly connected with the fixed connecting rod 14, and the movable connecting rod 13 drives the first surrounding part 11 to move close to or away from the second surrounding part 12 when the movable connecting rod 13 moves along the axis thereof. The first surrounding part 11 and the second surrounding part 12 are both hollow cylindrical structures, so that a limiting channel with a specific stroke can be generated when the first surrounding part 11 is coaxial with the second surrounding part 12, the effective constraint length of the channel is the distance from the first surrounding part 11 to the intercepting part 121 along the axis, and the effective constraint diameter of the channel is the inner diameter of the first surrounding part 11 and the second surrounding part 12. When the oxygen cylinder passes through the first surrounding part 11 and abuts against the intercepting part 121 under the action of gravity, it is considered to be constrained. Oxygen cylinders have various specifications, and by adjusting the relative position relationship between the fixed connecting rods 14 and the movable connecting rods 13, the distance between the first surrounding part 11 and the second surrounding part 12 can be changed, so that different lengths of oxygen cylinders can be accommodated.

[0028] In some embodiments of the present application, as shown in Figures 1-5 The number of fixed connecting rods 14 is at least two, the end of the fixed connecting rod 14 away from the movable connecting rod 13 is provided with a supporting section 141 which is perpendicular to the fixed connecting rod 14, the number of movable connecting rods 13 is the same as that of the fixed connecting rods 14, and the end of the movable connecting rod 13 away from the fixed connecting rod 14 is provided with a holding section 131. When the transfer device is placed on the ground and the supporting leg 31 moves to the supporting position, the central axis of the supporting leg 31 is not parallel to the central axis of the supporting section 141, so that the supporting leg 31 and the supporting section 141 can abut against the ground at the same time to provide a stable supporting surface for the connecting frame.

[0029] In some embodiments of the present application, as shown in Figures 1-5As shown, the moving link 13 is provided with a reset pin 132 along the radial direction of the moving link 13, the fixed link 14 is hollow and the outer wall of the fixed link 14 is provided with a limiting hole 142, the limiting holes 142 are linearly distributed along the movement direction of the moving link 13, and the reset pin 132 is limited from moving when the reset pin 132 extends out of the outer wall of the fixed link 14 through the limiting hole 142. The reset pin 132 can be compressed along the radial direction of the moving link 13 and retracted into the moving link 13, and the reset pin 132 is constrained by the outer wall of the fixed link 14 when the moving link 13 moves in the fixed link 14. When the reset pin 132 is aligned with the limiting hole 142, the reset pin 132 extends out of the limiting hole 142 to prevent the moving link 13 from moving along the axial direction of the moving link 13. Since the number of the moving links 13 is at least two, any moving link 13 will not rotate around the axial direction of the moving link 13 when the corresponding fixed link 14 slides relative to the moving link 13, which makes the linearly distributed limiting holes 142 always in the movement path of the reset pin 132. When the reset pin 132 extends out of different limiting holes 142, the first ring 11 can correspond to the second ring 12 to constrain oxygen cylinders of different length specifications. Specifically, the reset pin 132 includes a spring and a pin body, the spring is arranged in the moving link 13, and the pin body can be retracted into the moving link 13 under the action of an external force or extended out of the limiting hole 142 under the driving of the spring.

[0030] In some embodiments of the present application, as shown in Figures 1-5 The first ring 11 includes at least two coaxial first constraint rings 111, and the second ring 12 includes at least two coaxial second constraint rings 122. The first constraint rings 111 are connected with the moving links 13, and the second constraint rings 122 are connected with the fixed links 14. Strengthening ribs 112 are arranged between adjacent first constraint rings 111, and strengthening ribs 112 are also arranged between adjacent second constraint rings 122. The arrangement direction of the strengthening ribs 112 is the same as the axial direction of the first ring 11, which is beneficial to improve the structural strength of the first ring 11 and the second ring 12, and is also beneficial to maintain the coaxial relationship between the first ring 11 and the second ring 12.

[0031] In some embodiments of the present application, as shown in Figures 1-5 The base plate 21 is sleeved on the outer wall of the fixed link 14, and the number of the base plates 21 is at least two. At least one hook 22 is arranged on each base plate 21, and the arrangement positions of the base plates 21 on the corresponding fixed links 14 are the same. The outer edge of the stretcher bed hung by the hooks 22 is perpendicular to the fixed links 14, so that the oxygen cylinders are perpendicular to the bed plate of the stretcher bed, which is beneficial to maintain the stability of the oxygen cylinders and the transfer device when the stretcher bed moves. The medical staff only needs to hold with one hand, which can effectively prevent the oxygen cylinders from rolling over or falling off, and is beneficial to greatly reduce the energy and physical exertion of the medical staff.

[0032] In some embodiments of the present application, as shown in Figures 1-5As shown, the connecting plate 15 is connected with the fixed connecting rod 14, the foot 31 is connected with the connecting plate 15, and the elastic member 32, which is one of an elastic band or a tension spring, is connected with the connecting plate 15.

[0033] In some embodiments of the present application, a positioning structure, which is specifically a positioning pin, is arranged between the foot 31 and the connecting plate 15. Specifically, the foot 31 and the connecting plate 15 are respectively provided with through holes, and the positioning pin can reciprocate along the axis direction of the through holes. When the foot 31 moves to the supporting position, the through holes of the foot 31 and the connecting plate 15 are aligned, so that the positioning pin can pass through the two through holes and fix the relative position relationship between the foot 31 and the connecting plate 15, thereby fixing the relative position relationship between the foot 31 and the supporting section 141, so that the device can stably stand on the ground when the oxygen cylinder is accommodated or not accommodated.

[0034] In some embodiments of the present application, as shown in Figures 1-5 The connecting plate 15 is provided with an anti-collision member 151, and the foot 31 abuts against the anti-collision member 151 when the foot 31 moves to the initial position. The anti-collision member 151 plays a buffering role when the foot 31 collides with the connecting plate 15, which is beneficial to greatly reduce the sound generated when the foot 31 moves to the initial position, thereby improving the service life of the connecting plate 15 and the foot 31, and preventing the patient from being startled. The end of the foot 31 away from the connecting rod frame 1 is provided with an anti-skid member 311, and the material of the anti-skid member 311 is one of rubber, silicone or plastic, and the material of the anti-collision member 151 is the same as that of the anti-skid member 311.

[0035] In some embodiments of the present application, as shown in Figures 1-5 The connecting rod frame 1 is also symmetrically provided with wheels 16 on both sides, and the central axes of the wheels 16 on both sides coincide. When the foot 31 moves to the supporting position, the wheels 16, the anti-skid member 311 and the supporting section 141 are respectively abutted against the ground. Although the central axes coincide, the shafts connected with the wheels 16 on both sides are different, so that the wheels 16 on both sides can independently rotate, which makes the transfer device flexible to turn. By arranging the anti-skid member 311, when the transfer device is placed on the ground and the foot 31 moves to the supporting position, if the wheels 16 on both sides have the same movement trend, the anti-skid member 311 limits the transfer device to do linear motion; if the wheels 16 on both sides independently move, the anti-skid member 311 limits the transfer device to do circular motion.
