Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, and in particular relates to a medical infusion stand. Background Technology

[0002] Intravenous infusion is one of the most common methods of drug administration in clinical treatment. Infusion stands are commonly used auxiliary tools in intravenous infusion. The height of the infusion stand directly affects the safety, effectiveness, and patient comfort of infusion therapy. When the infusion stand is too low, the hydrostatic pressure of the drug solution is insufficient, which may cause venous blood to flow back into the infusion tube, leading to needle blockage or intravascular coagulation. If the infusion stand is too high, the hydrostatic pressure is too high, and the drug drip rate is too fast, which may cause excessive circulatory load or local extravasation of the drug solution, resulting in tissue swelling. The appropriate infusion height also varies with the patient's infusion level and height. Therefore, a height-adjustable medical infusion stand is needed. Utility Model Content

[0003] The purpose of this invention is to achieve adjustable height of the infusion stand by using the threaded connection between the screwing part and the adjusting rod, and the limiting cooperation between the limiting part and the blocking part. By rotating the screwing part, the adjusting rod can move up and down within a certain range, thereby solving the problem in the above-mentioned background technology that the height of the infusion stand needs to be adjusted according to the patient's infusion level and height.

[0004] The specific technical solution of this utility model is as follows: A medical infusion stand includes a base, a support rod vertically mounted on the upper surface of the base, the support rod having a circular cross-section, and a screw-on component connected to the support rod, the screw-on component having an annular cross-section, a positioning groove provided around the outer periphery of the support rod, and a positioning element circumferentially provided on the inner wall of the screw-on component to mate with the positioning groove. The screw-on component achieves a rotatable connection with the support rod through the sliding engagement of the positioning element and the positioning groove. An adjusting rod with an annular cross-section is threaded onto the screw-on component. A connecting rod with a circular cross-section is provided at the top of the support rod, and a limiting element with a circular cross-section is provided at the top of the connecting rod. The outer periphery of the limiting element is in sliding engagement with the inner wall of the adjusting rod.

[0016] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] See Figures 1 to 5This embodiment discloses a medical infusion stand, including a base 1. A support rod 2 is vertically provided on the upper surface of the base 1. The support rod 2 has a circular cross-section. A screwing component 3 is connected to the support rod 2. The screwing component 3 has an annular cross-section. Further optimization is possible by providing anti-slip textures on the outer periphery of the screwing component 3 for easy screwing operation. A positioning groove 21 is provided around the outer periphery of the support rod 2. A positioning element 31, which matches the positioning groove 21, is provided circumferentially on the inner wall of the screwing component 3. The screwing component 3 achieves a rotatable connection with the support rod 2 through the sliding engagement of the positioning element 31 and the positioning groove 21. An adjusting rod 4 is threadedly connected to the screwing component 3. In this embodiment, the inner wall of the screwing component 3 has an internal thread, and the outer periphery of the adjusting rod 4 has an external thread that matches the internal thread. The adjusting rod 4 has an annular cross-section. A connecting rod 22 is provided at the top of the support rod 2. The connecting rod 22 has a circular cross-section. A limiting element 23 is provided at the top of the connecting rod 22. The limiting element 23 has a circular cross-section, and its outer diameter is larger than that of the connecting rod 2. The outer diameter of the infusion stand is such that the outer periphery of the limiting member 23 slides with the inner wall of the adjusting rod 4. A barrier 41 is provided circumferentially on the inner wall of the adjusting rod 4, with a circular cross-section. The outer periphery of the connecting rod 22 slides with the inner wall of the barrier 41. The limiting member 23 is located above the barrier 41. The top of the adjusting rod 4 is provided with a suspension part 6 for suspending the infusion container. When the infusion stand is in use, if the height needs to be adjusted, simply rotate the screw 3. Due to the sliding fit between the positioning member 31 and the positioning groove 21, the screw 3 will not move up or down, while the adjusting rod 4, which is threadedly connected to the screw 3, will move up and down, thereby achieving the purpose of adjusting the overall height of the infusion stand. This allows the height of the infusion stand to flexibly adapt to infusion users in different positions and of different heights, improving the patient's treatment comfort. The limiting fit between the limiting member 23 and the barrier 41 prevents the adjusting rod 4 from disengaging from the screw 3 during the upward movement, thus preventing safety accidents and improving the safety and reliability of the infusion stand height adjustment.

[0019] A storage mechanism 5 is fitted onto the outer periphery of the support rod 2. The storage mechanism 5 includes a positioning sleeve 51, which is fitted onto the support rod 2. Several opening slots 511 are arranged in a ring at the lower part of the positioning sleeve 51, and the opening slots 511 are axially arranged along the pipe wall. A fastener 52 is threaded onto the outer periphery of the positioning sleeve 51. The fastener 52 has a threaded hole 521, and the vertical section of the threaded hole 521 is trapezoidal. A shelf 53 is provided at the top of the positioning sleeve 51. Through the elastic contraction characteristics of the trapezoidal inner wall of the threaded hole 521 and the opening slots 511 on the positioning sleeve 51, the rotational motion of the fastener 52 is converted into the radial contraction force of the positioning sleeve 51, thereby reducing the diameter. The opening slots 511 on the periphery of the positioning sleeve 51 axially compress the pipe. The end of the tube is divided into multiple independent elastic flaps, giving this part the ability to deform radially. When the fastener 52 is tightened, the fastener 52 moves along the axial direction of the tube, and its conical inner wall gradually squeezes the elastic flaps of the positioning sleeve 51. Due to the inclined plane effect of the conical surface, the thrust generated by the axial force of the fastener 52 is decomposed into a radial component, forcing the flaps to retract towards the center, causing the diameter of the positioning sleeve 51 to shrink until it is in close contact with the outer wall of the support rod 2, generating friction to achieve clamping, thereby fixing the storage mechanism 5 to the support rod 2. Tightening the fastener 52 in the opposite direction causes the trapezoidal inner wall to disengage from the flaps, and the flaps rebound under elastic action, restoring the inner diameter of the positioning sleeve 51, allowing the storage mechanism 5 to move up and down to adjust its height. The shelf 53 can be used to place ready-to-use infusion containers and patients' mobile phones and other miscellaneous items.

[0020] A storage box 54 is provided on one side of the shelf 53. The storage box 54 is used to place infusion containers and patients' mobile phones and other miscellaneous items to prevent them from falling. An extension plate 55 is hinged to the other side of the shelf 53. In this embodiment, the shelf 53 and the extension plate 55 are hinged together. When the area of ​​the shelf 53 is not enough, the patient can unfold the extension plate 55 to expand the area of ​​the shelf 53 and meet the patient's needs.

[0021] The suspension part 6 includes a support 61. The lower surface of the support 61 is fixedly connected to the top of the adjusting rod 4. The top of the support 61 is provided with a vertical shaft 611. The vertical shaft 611 is rotatably connected to a suspension part 62. The lower surface of the suspension part 62 is provided with a shaft hole 621 that matches the vertical shaft 611. Several hooks 63 are rotatably connected to the side of the suspension part 62. The suspension part 62 is rotatably connected to the support 61 through the shaft hole 621 and the hole shaft of the vertical shaft 611. By rotating the suspension part 62, hooks 63 in different positions can be selected, which improves the flexibility of using the infusion stand.

[0022] The top of the vertical shaft 611 is provided with an anti-detachment component 612, and the top of the shaft hole 621 is provided with a limiting groove 622 that matches the anti-detachment component 612. Through the limiting cooperation between the anti-detachment component 612 and the limiting groove 622, the suspension component 62 can be prevented from falling off the support component 61 when rotating, thereby improving the stability and safety of the infusion stand.

[0023] The side of the suspension component 62 is provided with several slots 623, and hooks 63 are rotatably connected to the slots 623. The side of the support component 61 is provided with a locking groove 613 that is adapted to the hooks 63. When the hooks 63 are in use, the hook body of the hooks 63 is located in the locking groove 613. Through the cooperation between the hook body of the hooks 63 and the locking groove 613, the rotation of the suspension component 62 can be restricted, preventing the suspension component 62 from being rotated during the patient's infusion, which would affect the patient's infusion or even pull the infusion tube and cause injury to the patient.

[0024] The top of the hook 63 is provided with a shaft 631, and the two vertical walls of the groove 623 are provided with round holes 6231 that are used to match the shaft 631. The hook 63 achieves a rotatable connection with the suspension component 62 through the shaft 631 and the round hole 6231.

[0025] The hook 63 has a ball head 632 at its tip. The ball head 632 prevents the hook tip from piercing the infusion container when it is hung on the hook 63. The upper surface of the hanging part 62 has a ball groove 624 that matches the ball head 632. The ball head 632 and the ball groove 624 are magnetically connected. The bottom of the ball head 632 and the ball groove 624 can use magnetic materials. When the hook 63 is not in use, rotating the hook 63 will magnetically connect the ball head 632 and the ball groove 624 together, which increases the storage stability of the hook 63.

[0026] The lower surface of the base 1 is provided with several casters 7 for easy movement of the base 1. Further optimization is possible by using casters 7 as universal wheels with brakes. The side of the base 1 is provided with a hook groove 11, and a limit rod 111 is provided in the hook groove 11. The side of the base 1 is provided with a tow hook 12 that is used in conjunction with the limit rod 111. The tow hook 12 and the hook groove 11 are located opposite each other on both sides of the base 1. When storing or using the IV stand, if it is necessary to move multiple IV stands, simply hook the tow hook 12 of one IV stand with the limit rod 111 of the adjacent IV stand, and repeat this process to connect several IV stands together. One person can move multiple IV stands.

[0027] Working principle: When using the IV stand, if the height needs to be adjusted, simply rotate the screw 3. Due to the sliding engagement between the positioning part 31 and the positioning groove 21, the screw 3 will not move up or down, while the adjusting rod 4, which is threadedly connected to the screw 3, will move up and down, thereby achieving the purpose of adjusting the overall height of the IV stand. This allows the height of the IV stand to flexibly adapt to IV patients in different positions and of different heights, improving the patient's treatment comfort. The limiting engagement between the limiting part 23 and the blocking part 41 ensures that the adjusting rod 4 will not disengage from the screw 3 during the upward movement, preventing safety accidents and improving the safety and reliability of the IV stand height adjustment. The base 1 is equipped with a hook 12 and a limiting rod 111. When storing or using the IV stand, if multiple IV stands need to be moved, the hook 12 of one IV stand can be hooked onto the limiting rod 111 of the adjacent IV stand. By operating in sequence, several IV stands can be connected together, facilitating the movement of multiple IV stands.
