Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an infusion medicine suspension device. Background Art

[0002] In the field of medical care, infusion therapy is a common and important treatment method. As a key device supporting this process, the design and function of the infusion solution suspension device directly affect the patient's treatment experience and the convenience of operation for medical staff. Traditional infusion stands mostly use fixed heights or simple manual adjustment methods, which are not flexible and efficient when dealing with patients of different heights or when the infusion height needs to be adjusted frequently. In addition, these traditional devices lack a precise height adjustment mechanism, making it difficult to meet the needs of specific medical scenarios. For example, in emergency or intensive care environments, quickly and accurately adjusting the infusion height is crucial to ensuring treatment effectiveness.

[0003] With the development of medical technology and the increasing demand for patient care quality, a variety of IV stands with electric or mechanical adjustment functions have appeared on the market. However, these products often have problems such as complex structure, inconvenient operation, and insufficient stability. In particular, the function of quickly adjusting the infusion height and fine-tuning the coordinated adaptation in emergency situations still needs to be strengthened. Specifically: Although the existing electric adjustment IV stands can achieve height adjustment, their gear rack structure lacks a self-locking mechanism, which can easily cause the height of the infusion bag to slip due to vibration; and although the mechanical adjustment device has self-locking properties, it cannot take into account both rapid coarse adjustment and fine adjustment functions. In addition, neither type of device solves the risk of uncontrolled falling during rapid adjustment.

[0004] Therefore, in view of the above situation, there is an urgent need to develop an infusion solution suspension device that can achieve convenient, stable and precise height adjustment and is easy to operate, so as to overcome the shortcomings in current practical applications.

[0010] According to a further technical solution, the linkage shaft is arranged perpendicular to the transmission shaft, a lifting operating lever is fixed to the outer end of the transmission shaft, and a driving handle is rotatably installed on the end of the lifting operating lever away from the transmission shaft.

[0011] According to a further technical solution, both ends of the linkage shaft are rotatably connected to the inner wall of the transmission box and the side wall of the main body stabilizing column respectively.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 The figure shows an infusion solution suspension device provided by one embodiment of the present invention, comprising a suspension support plate 1 and a device support base 9. An adjustable height column 4 and a main body stabilizing column 6 are fixed to the lower side of the suspension support plate 1 and the upper side of the device support base 9, respectively. The adjustable height column 4 and the main body stabilizing column 6 are slidably connected. A hanging hook 2 is also installed on the lower outer ring of the suspension support plate 1. Multiple hanging hooks 2 can be evenly distributed around the circumference to facilitate the hanging of infusion bags / bottles. It also includes: A transmission box 12 is fixed to the upper part of the main stabilizing column 6. A transmission shaft 13 and a linkage shaft 19 are rotatably mounted on the transmission box 12. A worm 21 is fixed to the transmission shaft 13 on the inner side of the transmission box 12. A worm wheel 20 is fixed to the linkage shaft 19 on the inner side of the transmission box 12. The worm wheel 20 and the worm 21 are meshed and connected. A gear 22 is fixed to the linkage shaft 19 on the inner side of the main stabilizing column 6. A control component is provided on one side of the adjustable height column 4 with a second groove 16, and a rack 17 capable of meshing with the gear 22 is installed on one side of the second groove 16. The adjustable height column 4 is also equipped with a control component for controlling the movement of the rack 17 relative to the gear 22; Adjustment component: the adjustable height column 4 is also equipped with an adjustment component for adjusting the sliding resistance between it and the main body stabilizing column 6.

[0022] In an embodiment of the present invention, a conventional infusion suspension structure is formed by suspending a support plate 1, a device support base 9, an adjustable height column 4, a main body stabilizing column 6, and a hook 2. Furthermore, a transmission box 12 and other transmission components are stacked. When the rack 17 is engaged with the gear 22, the transmission shaft 13 is rotated, which in turn drives the worm gear 20 via the worm 21, thereby driving the coaxial gear 22 to rotate. This drives the rack 17 and the adjustable height column 4 to rise and fall. The worm 21 and worm gear 20 have a self-locking effect, automatically maintaining stability after adjustment. Furthermore, if the adjustable height column 4 needs to be quickly raised or lowered, the control assembly can be used to control the rack 17 to move away from the gear 22. This allows the adjustable height column 4 to be quickly adjusted to its proper position, and then fine-tuned by rotating the transmission shaft 13. The adjustment assembly can adjust the sliding resistance between the adjustable height column 4 and the main body stabilizing column 6, thereby preventing the adjustable height column 4 from rapidly descending after the rack 17 separates from the gear 22, thereby improving its reliability.

[0023] In summary, the present invention ensures the convenience, stability and reliability of height adjustment of the infusion device through the worm gear self-locking mechanism and the fine adjustment and quick adjustment functions of the adjustable height column 4.

[0024] like Figure 1-4 As shown, as a preferred embodiment of the present invention, a plurality of rollers 10 are installed circumferentially on the bottom of the device supporting base 9, which is convenient for moving the device. The rollers 10 are preferably provided with a locking structure to ensure their stability, which is not limited or elaborated.

[0025] In order to improve the stability of the main stabilizing column 6, a plurality of structural reinforcement ribs 8 are circumferentially distributed and fixed between the main stabilizing column 6 and the device supporting base 9. The structural reinforcement ribs 8 can improve the overall structural strength.

[0026] In order to facilitate the movement of the device, the entire device is made of lightweight materials. A holding handle 11 is fixed to the upper part of the main stabilizing column 6, and the holding handle 11 is used to facilitate the movement of the device.

[0027] In order to prevent the adjustable height column 4 from slipping, a limit rope 18 is fixed to the lower end of the adjustable height column 4. The lower end of the limit rope 18 is fixedly connected to the inner bottom of the main stabilizing column 6. The length of the limit rope 18 can be set as needed.

[0028] The linkage shaft 19 and the transmission shaft 13 are arranged vertically, and the two ends of the linkage shaft 19 are rotatably connected to the inner wall of the transmission box 12 and the side wall of the main stabilizing column 6 respectively. A lifting control lever 14 is fixed to the outer end of the transmission shaft 13, and a driving handle 15 is rotatably installed on the end of the lifting control lever 14 away from the transmission shaft 13. Operating the driving handle 15 can drive the transmission shaft 13 to rotate.

[0029] like Figure 1-4 As shown in Figures 7-9, as a preferred embodiment of the present invention, a first groove 3 is formed on one side of the upper portion of the adjustable height column 4, and an avoidance opening 7 is formed on the main stabilizing column 6 corresponding to the first groove 3. A second cavity 35 is formed on the inner side of the adjustable height column 4, and the rack 17 slides into the second cavity 35. The control assembly includes a spring 33 and an unlocking handle 5. Notches 34 are formed at both ends of the rack 17, and a spring 33 is fixed to the notch 34. The other end of the spring 33 is fixedly connected to the end of the second cavity 35 away from the rack 17. An unlocking handle 5 is also provided in the first groove 3. The unlocking handle 5 adopts a U-shaped structure, and the two branches of the unlocking handle 5 slide into the second cavity 35 and are fixedly connected to the rack 17. When there is no external force, the rack 17 and the gear 22 are in a meshing connection state under the elastic force of the spring 33. Pulling the unlocking handle 5 can separate the rack 17 and the gear 22, thereby releasing the meshing connection state, making it convenient for manual operation to quickly raise and lower the adjustable height column 4.

[0030] like Figure 1-6 As shown in FIG. 2 , as a preferred embodiment of the present invention, a first cavity 27 is further provided on the inner side of the adjustable height column 4. The adjustment assembly includes a support block 23, an outer tube 24, an inner rod 25, a damping wheel 26, a wheel axle 28, an abutment plate 29, a threaded cylinder 30, a wheel frame 31 and a screw 32. The support block 23 is fixed in the first cavity 27. The outer tube 24 is fixed through the support block 23. The upper end of the outer tube 24 extends from the top of the suspension bearing plate 1, and the outer tube 24 is fixedly connected to the suspension bearing plate 1. Then, an inner rod 25 is rotatably installed on the inner side of the outer tube 24, a knob is fixed to the upper end of the inner rod 25, a screw 32 is fixed to the lower end of the inner rod 25, a wheel frame 31 is fixed to the lower end of the outer tube 24, a damping wheel 26 is rotatably installed on the wheel frame 31 through a wheel axle 28, the damping wheel 26 abuts against the inner wall of the main stabilizing column 6, a threaded cylinder 30 is also slidably provided on the wheel frame 31, and the inner rod 25 is threadedly connected to the threaded cylinder 30, and an abutment plate 29 abutting against the damping wheel 26 is fixed to the lower end of the threaded cylinder 30. The support block 23 can provide stable support for the outer tube 24 and other components. The operating knob drives the inner rod 25 to rotate, which can drive the screw 32 to rotate. Since the screw 32 is threadedly connected to the threaded barrel 30, the threaded barrel 30 can be driven to rise and fall, thereby adjusting the abutment tightness between the abutment plate 29 and the damping wheel 26, and then controlling the resistance of the damping wheel 26 to the rotation relative to the main stabilizing column 6, completing the adjustment of the sliding resistance between the adjustable height column 4 and the main stabilizing column 6, avoiding the rapid decline of the adjustable height column 4 after the rack 17 is separated from the gear 22, and improving its reliability.

[0031] The outer edge of the damping wheel 26 is coated with a polyurethane rubber layer with a Shore hardness of 70±5 HA. By rotating the inner rod 25 with a knob, the screw 32 is driven, causing the threaded barrel 30 to drive the abutment plate 29 downward, pressing the damping wheel 26. This increases the contact deformation between the damping wheel 26 and the inner wall of the main stabilizing column 6, thereby linearly increasing the sliding friction resistance.

[0032] The above-described embodiment of the present invention provides an infusion suspension device. A self-locking mechanism is implemented within the transmission box 12, utilizing a worm gear 20 and worm 21 to ensure stability after adjusting the infusion height. During operation, the worm 21 is rotated by rotating the lift lever 14 on the transmission shaft 13. This in turn drives the worm gear 20 and its coaxial gear 22, thereby raising and lowering the rack 17 meshing with the gear 22 and the adjustable height column 4.

[0033] If the height needs to be adjusted quickly, the rack 17 can be pulled out of the gear 22 by the unlocking handle 5 in the control assembly, thereby quickly adjusting the height of the adjustable height column 4, and then fine-tuning it to the desired position using the transmission shaft 13.

[0034] In addition, the adjustment component adjusts the relative position between the inner rod 25 and the threaded cylinder 30 through the knob, changes the pressure of the abutment plate 29 on the damping wheel 26 to adjust the sliding resistance and prevent the adjustable height column 4 from falling rapidly after the rack 17 is separated from the gear 22.

[0035] In summary, the design of the entire device not only ensures the convenience of height adjustment, but also improves the stability and reliability of use, while being easy to move and carry.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
