Description

Technical Field

[0001] This application relates to the field of medical care technology, and more specifically, to a medical care infusion device. Background Technology

[0002] Infusion stands are essential medical devices used to hang IV bottles or bags. The ceiling-mounted infusion stand is one type. This type of stand mainly consists of a track, a hanging rod with hooks on the outer bottom, and control buttons at the bottom of the rod. Holding the rod allows it to slide along the track, making the entire device relatively small in size compared to other types of IV stands. However, the control buttons at the bottom of the hanging rod prevent vertical IV stands from being stored within its hanging rod. While directly fixing the vertical IV stand to the outer wall of the hanging rod with fasteners reduces the footprint, it is more difficult to remove and requires moving the IV bottle or bag from the ceiling-mounted stand to the hanging bracket on the vertical stand. This fails to meet the requirement of maintaining a small footprint while also allowing for easier switching between vertical and vertical IV stands, making it inconvenient for patients. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a medical infusion device that allows for effortless switching between a suspended infusion stand and a floor-mounted infusion stand, while also enabling the floor-mounted infusion stand to be stored within the suspended infusion stand, maintaining the advantage of a small footprint and making it convenient for patients to use.

[0004] The medical infusion device according to an embodiment of this application includes a ceiling track component mounted on the ceiling, and further includes:

[0005] A suspended infusion frame includes a hanging cylinder mounted on the ceiling rail component. A rotation control component with a steel wire rope is installed at the bottom of the outer wall of the hanging cylinder. An installation hole is opened on the upper wall of the hanging cylinder. A guide wheel is rotatably installed in the installation hole. The steel wire rope extends into the hanging cylinder through the guide wheel. A hanging rod for suspending infusion bottles is detachably fixed at the bottom of the hanging cylinder through the rotation control component.

[0006] The ground-mounted infusion frame includes a positioning post that is movably located in the inner cavity of the hanging cylinder and fixedly connected to the wire rope, an infusion cylinder located at the bottom of the positioning post, and a sliding base located at the bottom of the infusion cylinder.

The through hole A and the mounting hole are respectively opened at the bottom of the inner cylinder and the upper part of the outer cylinder A.

[0014] According to some embodiments of this application, the hanging rod includes a hollow sleeve fitted outside the positioning post and an annular block fixed to the bottom of the outer wall of the hollow sleeve. Hanging rods are provided at equal intervals on the outer wall of the annular block. A stepped groove is opened on the inner wall of the inner cylinder. The hollow sleeve can be inserted into the stepped groove from the bottom of the inner cylinder and communicates with the inner diameter of the inner cylinder. The through hole B and the annular groove are both provided on the hollow sleeve, and the hollow sleeve and the inner cylinder can be fixed by inserting the cylinder.

[0015] According to some embodiments of this application, the infusion cylinder includes an outer cylinder B connected to the bottom end of the positioning column and an inner rod sleeved inside the outer cylinder B. The inner rod has a sliding groove B, and an insert block B is slidably connected in the sliding groove B. A spring B is connected to the inner end of the insert block B and the inner end of the sliding groove B. The outer cylinder B has equidistant locking grooves that are adapted to the insertion of the insert block B. Both the insert block B and the locking grooves are polygonal in design.

[0016] According to some embodiments of this application, the medical infusion device further includes a rotating component mounted on a trolley. The rotating component includes a stepper motor, and the output end of the stepper motor is connected to a rotating rod that is rotatably connected to the two side walls of the trolley. The rotating rod is fixedly inserted through the outer cylinder A, and the outer cylinder A can be rotated by the stepper motor using the rotating rod.

[0017] According to some embodiments of this application, the annular block is provided with mounting grooves at equal intervals, and a U-shaped plate A is fixed at the bottom of the mounting groove. One end of the hanging rod is rotatably connected to the U-shaped plate A, and a spring C is fixed on both the outer wall of the hanging rod and the upper wall of the mounting groove. In its natural state, the spring C can pull the hanging rod to a vertical position. An annular slide rail is also connected to the outer wall of the annular block, and a limiting block for laterally positioning the hanging rod is slidably connected at equal intervals on the annular slide rail.

[0018] According to some embodiments of this application, the cross-section of the track cavity inside the annular slide rail is an inverted T-shaped design.

[0019] According to some embodiments of this application, the sliding base component includes two staggered and fitted base plates, with rollers installed at both ends of the bottom of the two base plates.

An electric telescopic rod is fixed on the opposite side of the L-shaped baffle and the shell, and the electric telescopic rod can drive the L-shaped baffle to move and block.

[0021] The beneficial effects of this application are:

[0022] When the ground-mounted IV stand needs to be deployed, the patient controls the rotating mechanism with one hand. This lowers the steel cable attached to the hanging cylinder, causing the positioning post, which is connected to the cable, to descend under gravity. At a certain position, the automatic locking mechanism on the positioning post engages and secures the hanging rod. The rotating mechanism then separates the hanging rod from the hanging cylinder, allowing the steel cable to continue extending. The sliding base will then touch the ground. Separating the steel cable from the positioning post allows the ground-mounted IV stand to be detached from the suspended IV stand. The patient can then use the ground-mounted IV stand independently. This single operation allows for easy switching between the suspended and ground-mounted IV stands, saving effort and making it more convenient for the patient. Furthermore, the shared hanging rod between the two types of IV stands reduces operating costs.

[0023] When the ground-mounted infusion stand is not in use, the wire rope can be re-fixed to the positioning column and the rotating control device can be used to retract the ground-mounted infusion stand into the hanging cylinder of the suspended infusion stand. During the storage process, the hanging cylinder and the hanging rod are reassembled and fixed. This design also maintains the advantage of the infusion equipment having a small footprint. At the same time, it saves space occupied during storage compared to directly fixing the vertical infusion stand to the outer wall of the ceiling track infusion stand with fasteners.

[0024] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0046] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The following description, with reference to the accompanying drawings, describes a medical care infusion device according to an embodiment of this application.

[0049] like Figure 1 , Figure 3 As shown, the medical care infusion device according to an embodiment of this application includes:

[0050] Including the ceiling track component 100 installed on the ceiling, it also includes:

[0051] The suspended infusion frame component 200 includes a hanging cylinder component 210 mounted on the ceiling rail component 100. A rotation control component 220 with a steel wire rope 228 is installed at the bottom of the outer wall of the hanging cylinder component 210. An installation hole 212 is opened on the upper wall of the hanging cylinder component 210. A guide wheel 230 is rotatably installed in the installation hole 212. The steel wire rope 228 extends into the hanging cylinder component 210 through the guide wheel 230. A hanging rod component 240 for suspending infusion bottles is detachably fixed at the bottom of the hanging cylinder component 210 through the rotation control component 220.

[0052] The ground-mounted infusion frame component 300 includes a positioning post 310 that is movably located in the inner cavity of the hanging cylinder component 210 and is fastened and fixed with a wire rope 228, an infusion cylinder component 320 located at the bottom of the positioning post 310, and a sliding base component 330 located at the bottom of the infusion cylinder component 320. The positioning post 310 is provided with an automatic locking component 340, which is detachably fixed to the hanging rod component 240 by the retraction and extension of the wire rope 228.

[0053] The above solution involves housing the ground-mounted infusion frame component 300 within the suspended infusion frame component 200. Under normal conditions, the ground-mounted infusion frame component 300 does not need to be removed from the suspended infusion frame component 200. When the patient wants to move out of the track area (e.g., to use the restroom or to move around and get some fresh air in other parts of the hospital), the patient controls the rotation control component 220 with one hand. The rotation control component 220 lowers the steel wire rope 228 located inside the hanging cylinder component 210. The positioning post 310, which is connected to the steel wire rope 228, moves down by gravity. When it reaches a certain position, the automatic locking component 340 locks the hanging rod component 240 and the positioning post 310 together. After fixing, the hanging rod 240 is separated from the hanging cylinder 210 using the rotation control component 220. As the wire rope 228 continues to move downward, the sliding base 330 will touch the ground. Separating the wire rope 228 from the positioning column 310 will separate the ground-mounted infusion frame 300 from the suspended infusion frame 200. The entire downward movement process is mainly achieved using the rotation control component 220, which does not require much effort. Moreover, the ground-mounted infusion frame 300 can be moved by the patient himself, making it convenient for the patient to use. In addition, the fact that the two types of infusion stands share a single hanging rod 240 also saves on usage costs.

[0054] When the ground-mounted infusion frame 300 needs to be retracted into the suspended infusion frame 200, the wire rope 228 is fastened to the positioning column 310 at the opposite position. The rotating control component 220 is used to pull the wire rope 228 located inside the hanging cylinder 210, so that the positioning column 310 and the hanging rod 240 move upward together with the wire rope 228. When the hanging rod 240 is stuck at the bottom of the hanging cylinder 210, the rotating control component 220 is used to fix the hanging rod 240 and the hanging cylinder 210 again. At this time, the rotating control component 220 is used to control the wire rope 228 to move upward, and the automatic locking component 340 disengages from the hanging rod 240, so that the positioning column 310 and the infusion cylinder 320 can be smoothly retracted into the hanging cylinder 210, so that the entire device can be converted back into a suspended infusion stand for use. This design also maintains the advantage of the infusion equipment having a small footprint. Meanwhile, the relatively direct use of fasteners to fix the vertical IV stand to the outer wall of the ceiling-mounted IV stand also saves space during storage.

[0055] like Figure 6 and 8As shown, the rotation control component 220 includes a rotating shaft 221 on which a steel wire rope 228 is wound, and mounting blocks 223 rotatably connected to both ends of the rotating shaft 221 and fixed by connecting rods 222. One of the mounting blocks 223 is fixed to the bottom of the outer side of the lifting cylinder component 210. Specifically, the mounting block 223 is a ring-shaped block design with a bearing embedded in its inner ring that is connected to the rotating shaft 221, which facilitates the rotation and fixation of the rotating shaft 221 and the mounting block 223. A polygonal cavity 2211 is provided on the rotating shaft 221, through which both ends are connected. A polygonal block 224 is provided in the polygonal cavity 2211. A cylinder 225 is provided at one end of the polygonal block 224. Through holes A211 and B241 adapted to the cylinder 225 are respectively provided on the walls of the hanging cylinder 210 and the hanging rod 240. The cylinder 225 can move through the through holes A211 and B241 to achieve detachable fixation between the hanging rod 240 and the hanging cylinder 210. A positioning block is connected to the outer end of the polygonal block 224. A positioning rod 227 is screwed on the positioning block. Screw holes A2231 adapted to the positioning rod 227 are provided at equal intervals on the outer mounting block 223. Specifically, the positioning rod 227 can be screwed into the nearby screw hole A2231 when rotated to a certain position, which facilitates the storage of the ground-mounted infusion frame 300 into the suspended infusion frame 200. The positioning rod 227, which is screwed out from the screw hole A2231, can control the rotation and translation of the polygon block 224. When the ground-mounted infusion stand component 300 needs to be moved outward, rotate the positioning rod 227 so that its end disengages from the corresponding screw hole A2231. Continue rotating the positioning rod 227 on the positioning block to release the steel wire rope 228 wound around the rotating shaft 221. At this time, the positioning post 310, which is fastened to the steel wire rope 228, will move down by gravity. It will move down to the automatic locking component 340 to lock the hanging rod component 240 and the positioning post 310. Pull the positioning rod 227 outward so that the cylinder 225 moves out of the through hole B241. The fixed relationship between the hanging rod component 240 and the hanging cylinder component 210 can be released, leaving only the locking relationship between the hanging rod component 240 and the positioning post 310. Continue rotating the positioning rod 227 to drive the sliding base component 330 at the bottom of the infusion cylinder component 320 to the ground. Then, the originally fastened positioning rod 227 and the steel wire rope 228 are separated, thus realizing the conversion from a hanging infusion stand to a vertical infusion stand, which is convenient for patients to use.

[0056] like Figure 6 As shown, the inner wall of the polygonal cavity 2211 is adhered to an anti-slip rubber pad 229 that is attached to the polygonal block 224; the frictional force between the anti-slip rubber pad 229 and the polygonal block 224 can indirectly increase the stability of the positioning rod 227 during movement. Both the positioning post 310 and the outer wall of the polygonal block 224 have scale lines (not shown). The markings on the scale lines allow the patient to better control the rotation or translation of the positioning rod 227, further improving the stability of the positioning rod 227 during operation.

[0057] like Figure 10 , Figure 13 As shown, the inner wall of the hanging rod 240 is provided with an annular groove 242 that is adapted to the automatic locking component 340. Specifically, the annular groove 242 has a semi-circular cross-section. The positioning post 310 has a sliding groove A311 for installing the automatic locking component 340. The automatic locking component 340 includes a spring A341 and two inserts A342 connected to its two ends and having a T-shaped cross-section. The spring A341 and the two inserts A342 are all located in the sliding groove A311. In the natural state, the end of the insert A342 exposed outside the positioning post 310 is designed as a hemispherical shape. The insert A342 can be inserted into the matching annular groove 242 under the action of gravity. Due to the weight of the steel wire rope 228 and the positioning post 310 and its lower structure, during the downward movement of the positioning post 310, the insert block A342 will pass through the annular groove 242 and extend into the annular groove 242 by the release force of the spring A341, thereby achieving detachable fixing of the positioning post 310 and the hanging rod 240.

[0058] like Figure 13 As shown, at least two automatic locking components 340 are designed, and all automatic locking components 340 are evenly distributed on the positioning post 310. Adding multiple automatic locking components 340 allows the positioning post 310 to engage with the hanging rod 240 from more angles, increasing the stability of their connection and indirectly improving the stability of the hanging rod 240 when suspending the infusion bottle or bag.

[0059] like Figure 6 , Figure 8 As shown, a key buckle 226 is fixedly connected to the outer end of the wire rope 228, and a lifting ring 350 is connected to the top of the positioning post 310. The key buckle 226 and the lifting ring 350 are fastened together. The fastening relationship between the key buckle 226 and the lifting ring 350 makes it easy to separate the positioning post 310 from the wire rope 228, thereby indirectly achieving complete separation of the ground-mounted infusion frame component 300 from the suspended infusion frame component 200.

[0060] like Figure 2 , Figure 13 As shown, the ceiling track component 100 includes a housing 110 mounted on the ceiling and an I-shaped inner rail 120 connected to the inner top wall of the housing 110. A trolley 130 is slidably mounted on the I-shaped inner rail 120, and a rubber pad (not shown) is adhered to the outer wall of the I-shaped inner rail 120 at the location corresponding to the trolley 130. The design of the rubber pad facilitates the stability of the trolley 130 during movement. The hanging cylinder component 210 is mounted on the trolley 130 and can slide along the I-shaped inner rail 120. When movement is required, medical staff or patients can hold the hanging rod component 240 to slide the entire device along the I-shaped inner rail 120, adjusting the infusion position of the hanging infusion stand for convenient patient use.

[0061] like Figure 5 , Figure 7As shown, the lifting cylinder 210 includes an outer cylinder A213 mounted on a trolley 130 and an inner cylinder 214 sleeved inside the outer cylinder A213. Locking bolts are installed on the outer wall of the outer cylinder A213, and holes adapted to the locking bolts are evenly spaced on the outer wall of the inner cylinder 214. Through holes A211 and mounting holes 212 are respectively located at the bottom of the inner cylinder 214 and the upper part of the outer cylinder A213. The engagement of the locking bolts with the threaded holes allows for easy adjustment of the relative positions of the inner cylinder 214 and the outer cylinder A213, enabling adaptive adjustment of the height of the lifting cylinder 210 from the bottom surface, facilitating use in indoor buildings of varying heights.

[0062] like Figure 4 , Figure 9 , Figure 10 , Figure 13 As shown, the hanging rod 240 includes a hollow sleeve 243 fitted over the positioning post 310 and an annular block 244 fixed to the bottom of the outer wall of the hollow sleeve 243. Hanging rods 245 are evenly spaced on the outer wall of the annular block 244, facilitating the hanging of infusion bottles or bags. A stepped groove is formed on the inner wall of the inner cylinder 214. The hollow sleeve 243 can be inserted into the stepped groove from the bottom of the inner cylinder 214 and communicate with the inner diameter of the inner cylinder 214. The stepped groove helps to limit the installation of the hanging rod 240. When the top of the hollow sleeve 243 reaches the bottom of the stepped groove and the annular block 244 abuts against the bottom of the inner cylinder 214, the cylinder 225 can be used to fix the hollow sleeve 243 to the inner cylinder 214. The inner diameter of the hollow sleeve 243 does not obstruct the movement of the positioning post 310 within the inner cylinder 214. Both the through hole B241 and the annular groove 242 are provided on the hollow sleeve 243, and the hollow sleeve 243 and the inner cylinder 214 can be fixed by inserting a cylinder 225. Under the control of the positioning rod 227, the cylinder 225 can be inserted into or removed from the through hole B241, thereby fixing or disassembling the hollow sleeve 243 and the inner cylinder 214; and the design of the annular groove 242 can be used in conjunction with the automatic snap-fit ​​component 340 to realize the installation of the hollow sleeve 243 and the positioning post 310.

[0063] like Figure 8 , Figure 11As shown, the infusion cylinder 320 includes an outer cylinder B321 connected to the bottom end of the positioning post 310 and an inner rod 322 sleeved inside the outer cylinder B321. The inner rod 322 has a sliding groove B3221. An insert block B323 is slidably connected in the sliding groove B3221. A spring B324 is connected to the inner end of the insert block B323 and the inner end of the sliding groove B3221. The outer cylinder B321 has equidistant locking grooves 3211 that are adapted to the insertion of the insert block B323. Both the insert block B323 and the locking grooves 3211 are polygonal in shape. Press the insert block B323 in the locking groove 3211 and pull the outer cylinder B321 upward so that the insert block B323 is realigned with the locking groove 3211 slightly above. The pushing force of the spring B324 causes the insert block B323 to snap into the new locking groove 3211, thereby expanding the overall length of the outer cylinder B321 and the inner rod 322 after combination, which can meet the height adjustment of the vertical infusion stand.

[0064] The aforementioned suspended infusion stand is usually in a suspended state, that is, the hanging cylinder 210 containing the ground-mounted infusion stand component 300 is always perpendicular to the ceiling rail component 100, making it difficult to store it inside the ceiling rail component 100. Although it reduces the floor area and reduces the space occupied to a certain extent, it cannot further reduce the space occupied, resulting in safety hazards for patient movement.

[0065] To solve the above problem, the specific configuration of the present invention is as follows: Figure 7 , Figures 14-15 As shown, the medical infusion device also includes a rotating component 400 mounted on a trolley 130. The rotating component 400 includes a stepper motor 410, and the output end of the stepper motor 410 is connected to a rotating rod 420 that is rotatably connected to both side walls of the trolley 130. The rotating rod 420 is fixedly inserted through the outer cylinder A213. The stepper motor 410 can drive the outer cylinder A213 to rotate ±90° using the rotating rod 420. Before turning off the lights at night, the stepper motor 410 is started to drive the rotating rod 420 to rotate, causing the outer cylinder A213 to rotate and fold under the I-shaped inner rail 120. This smoothly folds the suspended infusion frame component 200 and the ground-mounted infusion frame component 300 under the ceiling rail component 100, reducing the space occupied and indirectly improving the safety of patients' nighttime activities, making it easier for patients to use.

[0066] like Figure 4 , Figure 9As shown, the annular block 244 has equidistant mounting grooves 2441. A U-shaped plate A246 is fixed at the bottom of the mounting groove 2441. One end of the hanging rod 245 is rotatably connected to the U-shaped plate A246. A spring C247 is fixed on both the outer wall of the hanging rod 245 and the upper wall of the mounting groove 2441. In its natural state, the spring C247 can pull the hanging rod 245 to a vertical position. An annular slide rail 248 is also connected to the outer wall of the annular block 244. A limiting block 249 for laterally positioning the hanging rod 245 is equidistantly connected to the annular slide rail 248. When in normal use for intravenous infusion, rotate the hanging rod 245 downwards until its side wall fits against the bottom of the mounting groove 2441. Slide the limiting block 249 on the annular slide rail 248 to limit the hanging rod 245, thus adjusting the hanging rod 245 to a horizontal position for assisted infusion. When folding the infusion stand is required, slide the limiting block 249 away from the hanging rod 245. The tension of the spring C247 pulls the hanging rod 245 up to a vertical position, increasing the convenience of folding and storing the infusion stand. At the same time, when not in use during the day, the hanging rod 245 can also be adjusted to a vertical position, reducing the risk of injury caused by accidental collisions with the scraper 245 by patients or family members.

[0067] like Figure 4 As shown, the cross-section of the track cavity inside the annular slide rail 248 is an inverted T-shape. It should also be noted that the cross-section of the track cavity inside the annular slide rail 248 and the cross-section of the bottom of the limiting block 249 can also be I-shaped or circular. The purpose is to reduce the probability of the limiting block 249 accidentally detaching from the annular slide rail 248 and improve the stability of the connection between the limiting block 249 and the annular slide rail 248.

[0068] like Figure 12 , Figure 14 , Figure 16 As shown, the sliding base component 330 includes two staggered base plates 331. Rollers 332 are mounted at both ends of the bottom of each base plate 331. A U-shaped plate B333 is also provided on the upper base plate 331. Through holes C are opened at the center of the U-shaped plate B333 and the two base plates 331, and bolts A334 with nuts are provided to fix all three together. Through holes D are opened on both side walls of the U-shaped plate B333. A screw hole B, matching the through hole D, is opened at the bottom of the inner rod 322. Bolts B335 with nuts are provided on the screw hole B to fix the inner rod 322 and the U-shaped plate B333. When it is necessary to accommodate the folding of the infusion stand, loosening the nut on bolt A334 adjusts the relative position between the two base plates 331, and tightening the nut on bolt A334 moves the two base plates 331 to the desired position. Figure 14 and Figure 16Loosen the nut on bolt B335, rotate U-shaped plate B333 to a certain position, and then tighten the nut on bolt B335. This will adjust the sliding base 330 and inner rod 322 to the desired position. Figure 14 and Figure 16 This design allows for easy folding and storage of the IV stand.

[0069] Meanwhile, the two base plates 331 can be adjusted to stagger their positions using bolts A334 with nuts, so that the base plates 331 and the hanging rod 245 can be staggered so as not to affect the normal use of the hanging rod 245.

[0070] The aforementioned infusion stand equipment, since the infusion stand is suspended below or stored inside the ceiling rail component 100, usually uses medical disinfectant for disinfection in order to maintain the hygienic environment of the hospital. However, its height position limits the convenience of disinfection.

[0071] To solve the above problem, the specific configuration of the present invention is as follows: Figure 17 , Figure 18 As shown, an ultraviolet lamp 500 is fixed to the top of the housing 110. A pull-out opening is provided on the bottom side wall of the housing 110, and an L-shaped baffle 140 that can be inserted through the pull-out opening to block the open bottom of the housing 110 is movable. An electric telescopic rod 600 is fixed on the opposite side of the L-shaped baffle 140 and the housing 110. The electric telescopic rod 600 can drive the L-shaped baffle 140 to move and block the opening. When the suspended infusion frame component 200 and the ground-mounted infusion frame component 300 are folded and stored under the ceiling rail component 100, the electric telescopic rod 600 is used to retract and drive the L-shaped baffle 140 to block the open bottom of the housing 110 along the pull-out opening. The ultraviolet lamp 500 is then turned on to disinfect the equipment inside the housing 110 for a certain period of time, which improves the convenience of disinfection of infusion equipment.

[0072] Specifically, the working principle of this medical infusion device is as follows: When the ground-mounted infusion frame 300 needs to be moved outward, the positioning rod 227 is rotated so that its end disengages from the corresponding screw hole A2231. Continuing to rotate the positioning rod 227 on the positioning block causes the steel wire rope 228 inside the hanging cylinder 210 to move downward. Simultaneously, the positioning post 310, which is connected to the steel wire rope 228, also moves downward or falls due to gravity. When it reaches a certain position, the insertion block A342 aligns with the annular groove 242 and extends into the annular groove due to the release force of the spring A341. Within the groove 242, the positioning post 310 and the hanging rod 240 are detachably fixed. Pulling out the positioning rod 227 allows the cylinder 225 to be removed from the through hole B241, thus releasing the fixed relationship between the hollow sleeve 243 and the inner cylinder 214, leaving only the snap-fit ​​relationship between the hollow sleeve 243 and the positioning post 310. Continuing to rotate the positioning rod 227 causes the roller 332 to touch the ground, separating the key buckle 226 from the hanging ring 350, thereby realizing the conversion from a hanging infusion stand to a standing infusion stand, making it convenient for patients to use when going to the toilet or walking to other nearby places.

[0073] When it is necessary to reassemble the ground-mounted infusion frame component 300 back into the suspended infusion frame component 200, the key buckle 226 is re-engaged with the lifting ring 350, and the positioning rod 227 is rotated to move the wire rope 228 inside the hanging cylinder component 210 upward, causing the positioning column 310 to move upward again into the inner cylinder 214, so that the hollow sleeve 243 is locked in the stepped groove at the bottom of the inner cylinder 214. At this time, the positioning rod 227 is pushed to make the cylinder 225 pass through the through hole A211 into the through hole B241, realizing the hollow sleeve 243 is fixed to the inner cylinder 214. The rotating positioning rod 227 continues to pull the steel wire rope 228 upward. The insert block A342 will move out of the annular groove 242 under the action of uniform tension. At this time, the positioning column 310 will continue to move upward. When the ground-mounted infusion frame component 300 retracts to a certain position in the inner cavity of the hanging cylinder component 210, the positioning rod 227 is aligned with the corresponding screw hole A2231 for fixing. The ground-mounted infusion frame component 300 and the suspended infusion frame component 200 can then be combined to complete the storage and reduce the floor space occupied by the infusion equipment.

[0074] Before turning off the lights at night, start the stepper motor 410 to drive the rotating rod 420 to rotate, which indirectly causes the outer cylinder A213 to rotate and fold under the I-shaped inner rail 120. This allows the suspended infusion frame component 200 and the ground-mounted infusion frame component 300 to be folded under the ceiling rail component 100, further storing the infusion equipment and indirectly improving the safety of patients' nighttime activities, while also reducing the space occupied.

[0075] When the suspended infusion frame component 200 and the ground-mounted infusion frame component 300 are folded under the ceiling rail component 100, the electric telescopic rod 600 retracts to drive the L-shaped baffle 140 to seal the open bottom of the cover 110 along the pull-out opening. The ultraviolet lamp 500 is turned on to disinfect the equipment inside the cover 110 for a certain period of time. The disinfection improves the safety of the medical environment.

[0076] It should be noted that the specific models and specifications of the stepper motor 410, ultraviolet lamp 500 and electric telescopic rod 600 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0077] The power supply and operating principle of the stepper motor 410, the ultraviolet lamp 500, and the electric telescopic rod 600 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
