Description

Technical Field

[0001] This invention relates to the field of medical care equipment technology, specifically to a multifunctional infusion stand with partitioned storage shelves. Background Technology

[0002] Intravenous infusion is the most widely used method of drug administration and supportive therapy in clinical diagnosis and treatment. As a core basic instrument for completing infusion therapy, the infusion stand is a key medical and nursing equipment in the field of biomedical engineering, designed for clinical nursing scenarios and adaptable to the needs of the entire diagnosis and treatment process. Existing conventional infusion stands mostly adopt a vertical, movable structure, with the core basic function of suspending and supporting infusion containers. With the upgrading of clinical diagnosis and treatment needs, additional functions such as storage trays, height adjustment, and tubing fixation have gradually emerged to adapt to diverse infusion scenarios such as outpatient, inpatient, emergency, and transport settings. With the continuous development of biomedical engineering technology, clinical requirements for infection control, ease of operation, and full-process safety management of infusion therapy are constantly increasing. Existing infusion stand designs mostly focus on optimizing single basic functions, failing to form a systematic solution for the core clinical needs of the entire infusion process, and thus struggling to meet the high-quality development requirements of modern clinical nursing.

[0003] Existing IV stands have numerous technical shortcomings in clinical applications that are incompatible with infection control standards, clinical nursing procedures, and infusion safety management requirements in the biomedical engineering field. The storage structure of existing IV stands is mostly an open, universal tray or a single, unisolated chamber, lacking physical isolation zones that meet infection control requirements. This easily leads to cross-contamination from the mixing of sterile medical consumables, patient personal items, and medical waste. Furthermore, the storage chamber lacks convenient access structures for small infusion consumables, making it difficult to remove items manually once they fall to the bottom, increasing nursing procedures and the risk of contamination. Simultaneously, they cannot meet the real-time disinfection needs of high-frequency use scenarios, and their overall functionality is fragmented, failing to meet the safety management requirements of the entire infusion process. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional infusion stand with partitioned shelving, in order to solve the problems mentioned in the background art. These problems include: the storage structure of existing infusion stands is mostly an open, universal tray or an unisolated, integral chamber, lacking physical isolation partitions that meet hospital infection control requirements, easily leading to cross-contamination of sterile consumables, patient personal items, and medical waste; the lack of a convenient structure for retrieving small consumables, making item retrieval inconvenient and increasing the risk of contamination; the absence of a real-time disinfection design for high-frequency scenarios; and the fragmented functions, making it difficult to adapt to the safety management requirements of the entire infusion process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional infusion stand with partitioned storage racks, comprising a base, a threaded rod fixed to the middle of the top of the base, and a support rod coaxially fixed to the top of the threaded rod. Several infusion hooks are fixedly arranged around the top of the support rod. A disc box is coaxially sleeved on the outer side of the middle of the support rod. A folding assembly is provided on the outside of the threaded rod. Several sealing covers are arranged around the top surface of the disc box.

[0006] Furthermore, the folding assembly includes a rotating sleeve, a limiting ring, and several pull rods. The rotating sleeve is threaded onto the outside of the threaded rod, the limiting ring is rotatably engaged onto the outside of the rotating sleeve, and the several pull rods are arranged around the outside of the limiting ring.

[0007] Furthermore, one end of each of the several pull rods is rotatably mounted outside the limiting ring, and a flip frame is rotatably mounted on the edge of the base corresponding to the position of each pull rod. A caster wheel is mounted on the bottom of the flip frame away from the base, and the other end of each of the several pull rods is rotatably mounted on the top of the flip frame on the corresponding side.

[0008] Furthermore, the opening and closing assembly includes a rotating ring and an auxiliary sleeve. The rotating ring is rotatably sleeved on the outside of the support rod near the disc box, and the auxiliary sleeve is rotatably sleeved on the outside of the support rod near the rotating ring. The bottom end of the auxiliary sleeve is fixedly connected to the top end of the rotating ring, and one end of each sealing cover is fixedly installed on the outside of the rotating ring.

[0009] Furthermore, the rotating ring has several sliding grooves that run through its interior. Each groove has a slider that is slidably engaged with it. The bottom end of the slider is fixedly connected to the top end of the connecting rod at the corresponding position. The storage cavity has an installation groove on the side wall facing the connecting rod. The top end of the slider is fixed with a handle.

[0010] Furthermore, a positioning block is slidably sleeved on the outer side of the connecting rod near its top end. One end of the positioning block is fixedly installed on the inner wall of the mounting groove. A return spring is sleeved on the outer side of the connecting rod. The two ends of the return spring are fixedly connected to the bottom surface of the positioning block and the top surface of the support plate, respectively. A positioning sleeve is fixed at the bottom end of the disc box. The positioning sleeve is sleeved on the outer side of the support rod. A threaded hole is opened through one side wall of the positioning sleeve, and a limit bolt is installed in the threaded hole.

[0011] Furthermore, the disinfection assembly includes a positioning rod, a piston block, and a collection cylinder. The positioning rod is vertically fixed to the middle of the inner bottom wall of the storage cavity. The piston block is fixed to the top of the positioning rod. The collection cylinder is slidably and sealingly sleeved on the outside of the piston block. A fixing frame is sleeved and fixed on the outside of the collection cylinder.

[0012] Furthermore, compression rods are vertically fixedly installed at both ends of the fixing frame, the bottom end of the compression rod is fixedly installed on the inner bottom wall of the storage cavity, and a compression spring is sleeved on the outside of the compression rod. The two ends of the compression spring are fixedly connected to the bottom surface of the fixing frame and the inner bottom wall of the storage cavity, respectively.

[0013] Furthermore, a one-way drain valve pipe is fixedly inserted through the middle of the top of the liquid collecting cylinder, a diversion cavity is opened in the middle of the bottom of the support plate, an annular cotton ring is fixedly fixed around the outside of the support plate, and several flow guiding channels communicating with the diversion cavity are opened around the inside of the support plate between the diversion cavity and the annular cotton ring. A sealing ring is fixed on the inner wall of the opening end of the diversion cavity facing the one-way drain valve pipe.

[0014] Furthermore, the disc box has a storage cavity inside, and a one-way liquid inlet valve pipe is fixedly connected to one side of the top of the liquid collecting cylinder. The input end of the one-way liquid inlet valve pipe is connected to the inside of the storage cavity, and an inlet pipe is provided between the outside of the top of the disc box and the inside of the storage cavity.

[0015] Compared with the prior art, the beneficial effects of the present invention are: Through the coordinated design of the folding assembly, opening and closing assembly, lifting assembly, and disc box, this infusion stand can quickly switch between static and transport states during use via the rotation sleeve, limiting ring, pull rod, and flip frame. This ensures stable support of the base without tipping or wobbling during static use, while the casters allow for flexible movement during transport. The storage slot provides temporary storage for commonly used instruments, and the rotating ring and auxiliary sleeve drive the sealing cover to easily open and close the independent storage chamber. This achieves physical isolation and partitioned storage in accordance with infection control standards in the biomedical engineering field. The handle, slider, slide, and connecting rod smoothly lift the support plate, facilitating the removal of small items from the storage chamber. The positioning block and return spring ensure smooth return to the starting position, avoiding the risk of contamination from hand insertion into the chamber. This design adapts to the diverse needs of the entire clinical infusion process.

[0016] By linking the disinfection and lifting components, this multi-functional infusion stand with partitioned shelves can centrally store and replenish disinfectant through the storage chamber and inlet tube. A one-way inlet valve allows for unidirectional disinfectant replenishment. The positioning rod, piston block, and collection cylinder work together to automatically draw a measured amount of disinfectant when the support plate is raised, and when the support plate falls, the one-way drain valve forces the disinfectant into the distribution chamber, where it is evenly soaked in the annular cotton ring through the guide channel. A compression rod and spring ensure the stability of the collection cylinder's movement, and a sealing ring ensures the sealing of the flow channel connection. During the raising and lowering of the support plate, the annular cotton ring cleans and disinfects the inner wall of the storage chamber. High-frequency, real-time disinfection can be achieved without additional operation, effectively reducing the risk of cross-contamination and complying with infection control standards in the biomedical engineering field.

[0021] The folding assembly includes a rotating sleeve 9, a limiting ring 10, and several pull rods 8. The rotating sleeve 9 is threaded onto the outside of the threaded rod 2. The limiting ring 10 is rotatably engaged onto the outside of the rotating sleeve 9. Several pull rods 8 are arranged around the outside of the limiting ring 10.

[0022] One end of each of the several pull rods 8 is rotatably mounted on the outside of the limiting ring 10. A flip frame 6 is rotatably mounted on the edge of the base 1 corresponding to the position of each pull rod 8. A universal wheel 7 is mounted on the bottom of the flip frame 6 away from the base 1. The other ends of the several pull rods 8 are rotatably mounted on the outside of the top of the flip frame 6 on the corresponding side.

[0023] The opening and closing assembly includes a rotating ring 14 and an auxiliary sleeve 15. The rotating ring 14 is rotatably sleeved on the outside of the support rod 3 near the disc box 4. The auxiliary sleeve 15 is rotatably sleeved on the outside of the support rod 3 near the rotating ring 14. The bottom end of the auxiliary sleeve 15 is fixedly connected to the top end of the rotating ring 14. One end of each sealing cover plate 11 is fixedly installed on the outside of the rotating ring 14.

[0024] The rotating ring 14 has several grooves 19 that are circumferentially opened inside the ring body. Each groove 19 has a slider 18 that is slidably engaged inside. The bottom end of the slider 18 is fixedly connected to the top end of the connecting rod 22 at the corresponding position. The storage cavity 13 has an installation groove 17 on the side wall facing the connecting rod 22. The top end of the slider 18 is fixed with a handle 20.

[0025] A positioning block 21 is slidably sleeved on the outer side of the connecting rod 22 near its top end. One end of the positioning block 21 is fixedly installed on the inner wall of the mounting groove 17. A return spring 39 is sleeved on the outer side of the connecting rod 22. The two ends of the return spring 39 are fixedly connected to the bottom surface of the positioning block 21 and the top surface of the support plate 16, respectively.

A threaded hole is opened through one side wall of the positioning sleeve 23. A limit bolt 24 is installed in the threaded hole.

[0026] This embodiment of the multifunctional infusion stand with partitioned shelves is a specialized medical nursing device developed in the field of biomedical engineering to meet the nursing needs of the entire clinical intravenous infusion process. Its core working principle and operation process are as follows, fully adapting to the needs of all scenarios of clinical infusion, including static therapy, bedside transport, and nursing operations, and strictly conforming to the infection control standards and clinical nursing operation logic in the field of biomedical engineering: This IV stand can quickly switch between stable stationary and flexible transport modes according to clinical usage scenarios, adapting to diverse clinical needs such as outpatient infusion, inpatient bedside treatment, emergency, and transport. When stable stationary use is required, the rotating sleeve 9, which is fitted on the outside of the threaded rod 2, is rotated. The rotating sleeve 9 moves upward along the axis of the threaded rod 2, simultaneously driving the outer rotatable locking limit ring 10 upward. During the upward movement of the limit ring 10, the pull rod 8 arranged around it pulls the corresponding connected flip frame 6 upward along the hinge point of the base 1, causing the universal wheels 7 at the end of the flip frame 6 to rise and detach from the ground. At this time, the base 1 directly contacts the ground for support, and the overall center of gravity is concentrated in the center of the base 1, eliminating the risk of tipping over and swaying. This ensures the stability of the device during infusion treatment and prevents displacement of the IV stand. Adverse events such as needle slippage and infusion interruption caused by pulling the infusion tubing are prevented. When it is necessary to move and transfer the infusion stand, the rotating sleeve 9 is rotated in the opposite direction, causing the rotating sleeve 9 to move downward along the threaded rod 2. At the same time, the limiting ring 10 moves downward, and the pull rod 8 pushes the flipping frame 6 to flip downward, so that the caster 7 contacts the ground and lifts the base 1 off the ground. At this time, the infusion stand can be flexibly pushed by the caster 7 to complete the transfer. No additional auxiliary tools are required throughout the operation. A single person can quickly complete the state switch, which greatly improves the efficiency of clinical nursing operations and meets the clinical adaptability design requirements of devices in the field of biomedical engineering.

[0027] During the use of the IV stand, the height of the disc box 4 can be flexibly adjusted according to the needs of the operator and the usage scenario. The disc box 4 is coaxially sleeved on the outside of the support rod 3 through the positioning sleeve 23 fixed at the bottom. By loosening the limiting bolt 24 in the threaded hole on the side wall of the positioning sleeve 23, the disc box 4 can slide up and down along the axis of the support rod 3. After adjusting to the target height, tightening the limiting bolt 24 will make the end of the limiting bolt 24 abut against the outer wall of the support rod 3, thus completing the rigid limiting and fixing of the disc box 4. This structure can adapt to the height requirements of different scenarios such as nurses standing to prepare medicine, bedridden patients raising their hands to pick up objects, and young pediatric patients receiving IV infusions. It avoids patients getting up to pick up objects and pulling on the IV tubing, while reducing the frequency of nurses bending over and reducing the risk of occupational injury. It fully meets the ergonomic design requirements of clinical nursing and is the core embodiment of humanized design of nursing devices in the field of biomedical engineering.

[0028] This IV stand utilizes a multi-chamber partitioned structure in the disc box 4 to achieve categorized storage that complies with hospital infection control standards, addressing the core pain point of cross-contamination caused by mixed storage of items in existing IV stands. The storage slot 12 on the top surface of the disc box 4 can temporarily hold commonly used nursing instruments such as tourniquets and IV patches, facilitating easy access during operation. For sterile medical consumables, medications, and medical waste requiring sealed isolation, the opening and closing mechanism can be used to open and close the corresponding storage chamber 13. Rotating the auxiliary sleeve 15 synchronously drives the rotating ring 14, which is fixedly connected to it, to rotate coaxially around the support rod 3. During the rotation of the rotating ring 14, the outer fixed sealing cap is also rotated. The plate 11 rotates synchronously, causing the sealing cover 11 to misalign with the slot of the corresponding storage cavity 13, thus opening the storage cavity 13 to allow for the storage and retrieval of items. After storage and retrieval are completed, the auxiliary sleeve 15 is rotated in the opposite direction to reset the sealing cover 11 and cover the slot of the storage cavity 13, completing the full sealing and locking. This structure achieves physical hard isolation and partitioning through multiple independent storage cavities 13, which can strictly divide sterile areas, clean areas, and contaminated areas according to hospital infection control requirements, effectively reducing the risk of cross-contamination caused by the mixed storage of sterile consumables, patient personal items, and medical waste. It is highly consistent with the core design specifications for hospital infection control in the field of biomedical engineering and greatly improves the infection control capabilities during infusion therapy.

[0029] Addressing the clinical challenge of retrieving small infusion consumables from the bottom of the storage cavity 13 by hand, this infusion stand utilizes a lifting mechanism for convenient retrieval while completely eliminating the risk of contamination from inserting hands deep into the storage cavity 13. When retrieving a small item from the storage cavity 13, the handle 20 above the corresponding cavity is pulled upwards. The handle 20 causes the bottom-fixed slider 18 to slide upwards along the groove 19 on the rotating ring 14. Simultaneously, the slider 18 moves the bottom-fixed connecting rod 22 upwards, which in turn moves the sliding support within the storage cavity 13. The plate 16 is smoothly lifted along the cavity wall, simultaneously lifting the items stored on the support plate 16 to the slot position of the storage cavity 13. Items can be easily retrieved without reaching deep into the cavity, greatly simplifying the nursing operation steps and avoiding contamination of sterile consumables caused by hand contact with the depths of the cavity. After the items are removed, the handle 20 is released, and the return spring 39, sleeved on the outside of the connecting rod 22, springs back to its original position. The return spring 39 pushes the support plate 16 smoothly back down along the inner wall of the storage cavity 13 to the bottom of the cavity, simultaneously driving the connecting rod 22, the slider 18, and the handle 20 back to their initial state. The slide groove 19 extends through the rotating ring 14 axially. During the rotation of the rotating ring 14 to adjust the opening and closing of the sealing cover 11, the slider 18 can remain relatively stationary within the slide groove 19 and will not be displaced with the rotation of the rotating ring 14, thus avoiding structural motion interference and ensuring the independence and smoothness of the operation of each component. The positioning block 21 is sleeved on the outside of the connecting rod 22, which not only provides guidance and limit for the up and down sliding of the connecting rod 22, but also provides stable support for the return spring 39, ensuring the smoothness of the lifting process of the support plate 16 without jamming or displacement risk. It is well adapted to the durability requirements of high-frequency clinical use and meets the reliability design standards of medical devices in the field of biomedical engineering.

[0030] Example 2: Please refer to Figure 7 - Figure 11 This embodiment further describes Example 1. The disinfection assembly includes a positioning rod 27, a piston block 28, and a liquid collection cylinder 29. The positioning rod 27 is vertically fixed in the middle of the inner bottom wall of the storage cavity 13. The piston block 28 is fixed at the top of the positioning rod 27. The liquid collection cylinder 29 is slidably and sealingly sleeved on the outside of the piston block 28. A fixing frame 30 is sleeved and fixed on the outside of the liquid collection cylinder 29.

[0031] Compression rods 31 are vertically fixedly installed at both ends of the fixed frame 30. The bottom end of the compression rod 31 is fixedly installed on the inner bottom wall of the storage cavity 13. A compression spring 32 is sleeved on the outside of the compression rod 31. The two ends of the compression spring 32 are fixedly connected to the bottom surface of the fixed frame 30 and the inner bottom wall of the storage cavity 13, respectively.

[0032] A one-way drain valve pipe 34 is fixedly inserted through the middle of the top of the liquid collecting cylinder 29. A diversion cavity 35 is opened in the middle of the bottom of the support plate 16. An annular cotton ring 38 is fixedly fixed around the outside of the support plate 16. Several guide channels 37 that communicate with the diversion cavity 35 are opened around the inside of the support plate 16 between the diversion cavity 35 and the annular cotton ring 38. A sealing ring 36 is fixed on the inner wall of the opening end of the diversion cavity 35 facing the one-way drain valve pipe 34.

[0033] The disc box 4 has a storage cavity 25 inside. The top of the liquid collecting cylinder 29 is fixedly connected to a one-way liquid inlet valve pipe 33. The input end of the one-way liquid inlet valve pipe 33 is connected to the inside of the storage cavity 25. An inlet pipe 26 is provided between the outside of the top of the disc box 4 and the inside of the storage cavity 25.

[0034] In this embodiment, the disinfection component is a purely mechanical disinfection structure developed based on the core structure of Embodiment 1, specifically addressing the core needs of infection control in medical infusion devices in the biomedical engineering field. It is fully integrated with the lifting component throughout the entire process, enabling automated cleaning, wiping, and immersion disinfection of the inner wall of the placement cavity 13 without the need for additional disinfection instruments or manual reapplication of disinfectant. Its complete working principle, operation process, and technical effects are as follows: It is deeply coordinated with the lifting component's raising and lowering movements throughout the entire process, with no independent redundant operations, making it well-suited for high-frequency clinical use scenarios: Before use, medical alcohol or other compliant medical disinfectant can be injected into the storage chamber 25 inside the disc box 4 through the inlet tube 26 on the top surface of the disc box 4. The storage chamber 25 serves as a centralized liquid storage tank and is connected to the disinfection components in each storage chamber 13 through a one-way inlet valve tube 33. The one-way inlet valve tube 33 only allows the disinfectant to flow from the storage chamber 25 into the collection cylinder 29 in one direction, preventing the disinfectant from flowing back and ensuring the independent and stable liquid supply to the disinfection components in each chamber, thus avoiding cross-contamination.

[0035] When the inner wall of the storage cavity 13 needs to be disinfected after a period of use, the auxiliary sleeve 15 is pulled to drive the rotating ring 14, which is fixedly connected to it, to slide upward on the support rod 3. When the rotating ring 14 slides upward, through the locking structure of the sliding groove 19 and the slider 18, it synchronously drives the handles 20 and connecting rods 22 corresponding to all storage cavities 13 to move upward, thereby driving the support plate 16 in each storage cavity 13 to be smoothly lifted along the cavity wall, so as to realize the synchronous disinfection operation of the whole cavity. Alternatively, for a single contaminated storage cavity 13, the handle 20 can be pulled up by a single groove to realize the independent disinfection of a single cavity, which can adapt to different clinical use needs.

[0036] During the lifting process of the support plate 16, the annular cotton ring 38 fixed around its outer wall is in close contact with the inner wall of the storage cavity 13 throughout the process. As the support plate 16 continues to rise, the annular cotton ring 38 completes a full-coverage pre-cleaning wipe of the inner wall of the storage cavity 13, removing residual drug stains, debris and impurities from the cavity wall, and preparing for subsequent immersion disinfection. At the same time, during the upward movement of the support plate 16, the diversion cavity 35 at its bottom end is completely separated from the one-way drain valve pipe 34 at the top of the collection cylinder 29. Under the rebound force of the compression spring 32, the collection cylinder 29 slides upward along the compression rod 31 through the fixing frame 30, driving the collection cylinder 29 to slide upward along the piston block 28 at the top of the positioning rod 27, so that a negative pressure environment is formed inside the collection cylinder 29. Then, a certain amount of disinfectant is drawn from the storage cavity 25 into the collection cylinder 29 through the one-way inlet valve pipe 33, completing the automatic quantitative replenishment of disinfectant without the need for manual separate addition, greatly simplifying the disinfection operation process.

[0037] After completing the upward cleaning and disinfectant replenishment, the auxiliary sleeve 15 is released. Under the rebound force of the return spring 39 sleeved on the outside of the connecting rod 22, the support plate 16 smoothly descends along the inner wall of the placement cavity 13. During the descent, when the support plate 16 descends to the preset docking position, the sealing ring 36 fixed on the inner wall of the opening end of the diversion cavity 35 facing the one-way drain valve pipe 34 tightly abuts against the output end of the one-way drain valve pipe 34, forming a sealed and leak-free flow channel to prevent the disinfectant from overflowing during subsequent squeezing and dispensing. As the support plate 16 continues to descend, a continuous and stable downward pressure is formed on the collection cylinder 29 through the one-way drain valve pipe 34, driving the collection cylinder 29 along the compression rod 31 via the fixing frame 30. As the liquid slides downwards, the compression spring 32 is compressed synchronously, and the collection cylinder 29 slides downwards relative to the piston block 28. The piston block 28 forms a stable pressure on the disinfectant inside the collection cylinder 29, causing the disinfectant inside the collection cylinder 29 to be pressed unidirectionally into the diversion chamber 35 at the bottom of the support plate 16 through the one-way drainage valve pipe 34. Then, through the guide channel 37 that is opened around the diversion chamber 35 and the annular cotton ring 38, the disinfectant is evenly guided and soaked into the interior of the annular cotton ring 38, realizing automatic and uniform liquid application of disinfectant without manual application. This solves the common pain points of the industry, such as cumbersome disinfection operation and incomplete disinfection of the existing infusion stand storage chamber. It is highly consistent with the core design specifications for hospital infection control in the field of biomedical engineering and significantly reduces the risk of cross-infection related to infusion.

[0038] This disinfection unit adopts a purely mechanical linkage structure, requiring no external power supply or electric control components, thus posing no electrical safety risks. It is suitable for most clinical infusion scenarios, including outpatient infusion, bedside treatment, emergency care, and transport, and meets the safety design standards for medical devices. Each placement chamber 13 corresponds to an independent disinfection unit, and the disinfection process of each chamber does not interfere with each other, flexibly adapting to diverse needs such as single-chamber disinfection and simultaneous disinfection of all chambers. The ring-shaped cotton ring 38 uses medical-grade sterile consumables that can be quickly disassembled and replaced. All contact parts are made of medical-grade materials that are resistant to disinfection and corrosion, and can be repeatedly disinfected and reused, fully complying with the usage specifications of clinical medical consumables. Together with the partitioned storage and convenient retrieval structure of Example 1, it forms a hospital infection control system adapted to the entire infusion process, possessing outstanding creativity and clinical application value.
