Abstract
Description
Technical Field
[0001] This utility model relates to the field of infusion rod technology, specifically an adjustable infusion rod. Background Technology
[0002] Infusion stands are common medical devices in hospitals, used to hang IV bottles or medicine bags. Existing infusion stands include ceiling-mounted infusion stands and upright infusion stands, which are usually composed of support rods and hooks. Ceiling-mounted infusion stands are particularly common in wards.
[0003] Currently, ceiling-mounted IV stands typically adjust their extension length by pulling the inner rod, which slides along a groove on the outer rod. However, the end of the pull rod is quite close to the hook. Shorter medical staff need to stand on tiptoe or a stool to adjust the hook's height. Furthermore, to prevent the medication bag from pulling the hook downwards, the friction between the inner and outer rods is significant. When taller medical staff adjust the hook's height by pushing the inner rod into the outer rod, they need to ensure the inner and outer rods are perpendicular to the ceiling rail and pushed upwards. Otherwise, the force generated when the outer rod is tilted can easily damage the connection between the outer rod and the ceiling rail. Therefore, the practicality is not ideal, and there is room for improvement. Utility Model Content

[0023] 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.
[0024] In the prior art, an adjustable infusion rod includes a top rail 1 and an infusion rod 2. A movable roller 3 is driven and connected inside the top rail 1. A screw is provided at the lower part of the movable roller 3. The upper part of the infusion rod 2 is provided with a threaded hole and is threadedly connected to the screw. The movable roller 3 and the infusion rod 2 are connected together through the threaded connection between the screw and the threaded hole of the infusion rod 2. Then, the infusion rod 2 is pushed, and the movable roller 3 moves within the top rail 1, so that the infusion rod 2 moves along the top rail 1. The inside of the threaded hole is provided with an internal thread, and the outside of the screw is provided with an external thread that matches the internal thread. The two are matched for easy installation.
[0025] Please see Figures 1-6 This utility model discloses an adjustable infusion rod 2. The infusion rod 2 has a cavity 4 inside, and the lower part of the cavity 4 passes through the end of the infusion rod 2. A sliding rod 5 is inserted into the cavity 4, and a base 6 is provided at the lower part of the sliding rod 5. Hooks are provided around the base 6. The sliding rod 5 moves within the cavity 4 of the infusion rod 2, which can drive the base 6 and hooks to move up and down. A pull rod 7 is provided at the lower part of the base 6. Medical staff can grasp the pull rod 7 and pull it down to adjust the height of the hooks.
[0026] The infusion rod 2 has a through groove 8 on its side wall, and the sliding rod 5 has a limit block 9 on its side wall, which is through the through groove 8. The limit block 9 moves through the through groove 8 and can move with the sliding rod 5. The infusion rod 2 has several adjustment grooves on its side wall. During adjustment, the limit block 9 moves in the adjustment groove to adjust the position of the sliding rod 5 in the cavity 4 and adjust the height of the hook. After the limit block 9 is slid into the adjustment grooves of different heights, the sliding rod 5 is restricted and no longer moves in the cavity 4, thereby fixing the sliding rod 5 at that height and thus fixing the hook at that height.
[0027] A spring 10 is installed inside the cavity 4. The other end of the spring 10 is fixedly connected to the end of the sliding rod 5. The spring 10 provides tension to the sliding rod 5. When the limiting block 9 at one end of the sliding rod 5 slides into the adjustment groove, the spring 10 pulls the sliding rod 5 and fixes the limiting block 9 in the adjustment groove. The diameter of the spring 10 is smaller than the diameter of the cavity 4, so that the spring 10 is not affected by the cavity 4 when it extends or contracts.
[0028] The adjustment groove includes the travel groove 11. The limiting block 9 moves from the through groove 8 into the travel groove 11. The other end of the travel groove 11 is provided with a locking groove 12. The spring 10 pulls the limiting block 9 into the locking groove 12. When the hook moves to a height that medical staff can reach, the sliding rod 5 is rotated so that the limiting block 9 at one end of the sliding rod 5 slides into the corresponding travel groove 11 and then moves to the locking groove 12. Under the pulling force of the spring 10, it enters the locking groove 12, thereby fixing the sliding rod 5 and preventing it from rotating.
[0029] The top of the slot 12 is higher than the top of the travel groove 11 connected to it, so that when the limiting block 9 is inserted into the slot 12, the part above the travel groove 11 will not rotate under the restriction of the slot 12, and thus will not enter the travel groove 11.
[0030] The lower part of the lever 7 is equipped with a gripping part, and the outside of the gripping part is equipped with an anti-slip pad. When medical staff grasp the anti-slip pad and pull the lever 7 and rotate the lever 7, there will be no slippage.
[0031] In summary, when using this adjustable infusion rod for the first time, medical staff should grasp the gripping part of the pull rod 7 and pull it downwards to pull the limiting block 9 out of the slot 12 and move it into the travel groove 11. Then, rotate the pull rod 7 to drive the sliding rod 5 to rotate within the cavity 4, causing the limiting block 9 to slide from the travel groove 11 into the through groove 8. Afterwards, the sliding rod 5 can be pulled downwards to move downwards within the cavity 4, causing the lower hook to move downwards. When the hook reaches an accessible height, the limiting block 9 is moved into the closest travel groove 11, and the sliding rod 5 is rotated to slide the limiting block 9 into the travel groove 11. When it moves into the slot 12, the pull rod 7 is released, the spring 10 contracts, and the sliding rod 5 and other devices move upwards until the limiting block 9 is engaged in the slot 12.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
