Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a classification and identification device for a micro-infusion pump extension tube. Background Technology

[0002] Patients in the terminal stage of malignant tumors, those in the bone marrow suppression stage after chemotherapy, those complicated with septic shock, or those with multiple organ dysfunction often need to use multiple micro-infusion pumps simultaneously to continuously infuse chemotherapy drugs, vasoactive drugs, sedatives and analgesics, antiemetics, targeted agents, anti-infective drugs, and nutritional support solutions, in order to maintain circulatory stability, control tumor progression, relieve cancer pain symptoms, and ensure the continuity of treatment.

[0003] However, the multi-pump simultaneous infusion mode also brings some unresolved clinical nursing challenges: 1. Cancer patients often have multiple infusion channels such as central venous catheters (PICC, port-a-catheter, CVC) and peripheral venous access. When multiple micro-infusion pump extension tubes are superimposed, the irregular crossing of the tubing can easily lead to entanglement. Moreover, the current clinical practice commonly uses paper tape to directly stick the labels on the surface of the tubing. The font of the labels is generally small and the placement of the labels is inconsistent. Medical staff need to spend a lot of time sorting and identifying the tubing, which makes it difficult to quickly identify the tubing.

[0004] 2. Infusion sets should be changed every 24 hours. If contamination or compromised integrity is suspected, they should be replaced immediately. Infusion accessories (including micro-infusion pump extension tubing, T-connectors, infusion connectors, filters, etc.) should be replaced along with the infusion set. In other words, the micro-infusion pump extension tubing, as an infusion accessory, should be replaced every 24 hours along with the infusion set in routine clinical settings to reduce the risk of catheter-related bloodstream infections (CRBSI). However, in clinical practice, due to heavy nursing workloads and numerous patient tubing connections, healthcare professionals often find it difficult to accurately remember the specific replacement time for each extension tubing, resulting in the use of extension tubing beyond its expiration date.

[0005] 3. During shift handover, medication changes, and daily rounds, nurses need to repeatedly check tubing, verify labels, manually record information, and remind nurses to extend the tubing replacement time. These non-therapeutic operations consume a lot of nursing time, which not only increases the workload of nurses but also reduces the overall efficiency of nursing work.

[0006] Therefore, there is an urgent clinical need for an infusion pump extension tube management device that integrates functions such as anti-tangling, classification identification, and timer reminders to improve the efficiency of clinical nursing work and the level of medical safety. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model proposes a classification and labeling device for micro-infusion pump extension tubes. One objective of this utility model is to provide an extension tube management device that integrates anti-tangling and classification labeling. Another objective is to provide an injection pump extension tube management device that integrates anti-tangling, classification labeling, and timing reminder functions.

[0008] The technical solution to the technical problem solved by this utility model is as follows: A micro-infusion pump extension tube classification and marking device includes a box body and an openable and closable lid. The box body has a plurality of spaced-apart lower grooves along its width. The lid includes a cover body with a downwardly extending flange on its circumference. An upper groove is formed on the flange at a position corresponding to each of the lower grooves. When the lid is fastened to the box body, the lower grooves and the upper grooves align to form a cavity for the extension tube to pass through and for limiting its position. An identification sticker for marking the corresponding extension tube is detachably provided on the cover body at a position corresponding to each cavity.

[0009] Preferably, the cover is made of transparent material, the two ends of the label are provided with first magnets, and the cover body is provided with second magnets corresponding to the positions of the first magnets, and the first magnets can be magnetically connected to the second magnets.

[0010] Preferably, the label has a first fitting hole, in which the first magnet is fitted; the cover has a second fitting hole, in which the second magnet is fitted.

[0011] Preferably, the label is an erasable label made of erasable board material.

[0012] Preferably, one side of the lid is hinged to the corresponding side of the box body; the other side of the lid is magnetically attached to the corresponding side of the box body or is attached by Velcro.

[0013] Preferably, at least one first pipe clamp and a second pipe clamp are provided in the lower groove. The first pipe clamp includes a base, and the base is provided with two elastic claws arranged opposite to each other. A conductive sheet is embedded in the first pipe clamp, and the two contact ends of the conductive sheet extend to the outside of the two elastic claws respectively. Contact seats are provided on the inner wall of the lower groove at positions corresponding to the two contact ends. It also includes a sleeve fitted on the extension tube. When the extension tube drives the sleeve to be inserted into the first tube clamp, the sleeve expands outward with two elastic claws, so that the two contact ends of the conductive sheet respectively contact the corresponding contact seat to conduct electricity. The bottom of the box is provided with an installation cavity, and each of the installation cavities is provided with an independent control module corresponding to each of the lower grooves. The control module includes a power supply, a controller and an audible and visual alarm. The conductive sheet and two contact bases together form a switch, which is connected in series in the power supply circuit between the power supply and the controller. The controller has a built-in 24-hour timing unit, and the audible and visual alarm is connected to the output terminal of the controller. When the conductive plate makes contact with the contact base, the power supply circuit is closed, the controller is powered on and starts a 24-hour countdown. After the countdown ends, the controller controls the audible and visual alarm to issue an alarm reminder.

[0014] Preferably, the power source is a button cell battery.

[0015] Preferably, the sleeve has a slot on its wall along the axial direction that allows the extension tube to pass through.

[0016] Preferably, the audible and visual alarm includes an LED indicator and a buzzer; the controller has a built-in pre-reminder unit, and when the countdown has a preset duration remaining, the controller controls the LED indicator to flash at a first frequency to warn of an impending event; after the countdown ends, the controller controls the LED indicator to flash at a second frequency and simultaneously activates the buzzer to sound an alarm, the second frequency being higher than the first frequency.

[0017] Preferably, the bottom of the box body is also provided with a bottom cover that is adapted to the mounting cavity, and the four corners of the bottom cover are bolted to the box body by screws.

[0018] The above technical solution has the following advantages or beneficial effects: 1. This device forms independent cavities by aligning the lower and upper grooves, which separates and neatly arranges multiple micro-pump extension tubes, solving the problems of tangled and stacked tubes. At the same time, the labels are set one-to-one with the cavities, making the drug information intuitive and eye-catching. Medical staff can quickly locate the target tubes, significantly shortening the tube identification time.

[0019] 2. This device uses a conductive plate within the first tube clamp to interact with the contact base to form a trigger switch. Once the extension tube is installed, the power supply circuit automatically closes, triggering the controller to start a 24-hour countdown without additional operation. After the countdown ends, an audible and visual alarm proactively issues a replacement reminder, achieving independent control of "one tube, one timer, one alarm." This design eliminates the need for medical staff to manually record and remember the replacement time of each tube, effectively solving the problem of extended tubes being used beyond their expiration date in clinical practice, ensuring strict adherence to intravenous therapy nursing procedures, and reducing the risk of catheter-related bloodstream infections.

[0020] 3. This device adopts an openable and closable flip-top structure, making tubing installation and removal convenient; the label is detachable and uses an erasable material to quickly update drug information without repeatedly sticking tape; at the same time, each tubing corresponds to an independent control module, and the replacement and reset of a single tubing do not interfere with each other, significantly shortening the time spent on tubing sorting and verification during shift handover, drug changes, and daily rounds, reducing the nursing time occupied by non-therapeutic operations, and improving the efficiency of clinical nursing work.

[0021] 4. This device is compact in size and uses a built-in power supply, eliminating the need for external wiring. It can be flexibly installed in various locations such as bed rails and infusion pump stands. The sleeve has an axial groove, allowing for fitting without disconnecting the tubing, which is compatible with existing clinical extension tube usage habits. The installation cavity is equipped with a sealed bottom cover to protect the internal circuitry, combining flexibility in use with operational reliability. Attached Figure Description

Detailed Implementation

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] Example 1: like Figure 1 - Figure 3 As shown, this embodiment proposes a micro-infusion pump extension tube classification and marking device, which is the basic implementation of this utility model. It can independently realize the functions of anti-winding and neatness and classification and marking of the extension tube 14. It includes a box body 1 and an openable and closable cover 2. The box body 1 is generally a long rectangular box structure. The box body 1 is provided with a number of spaced-apart lower grooves 3 along the width direction. In this embodiment, the lower grooves 3 can be set to 6 to 8 groups, which can simultaneously accommodate the corresponding number of micro-infusion pump extension tubes 14, adapting to the clinical routine multi-pump simultaneous infusion needs. The cover 2 includes a cover body, and the circumference of the cover body is provided with a downwardly extending baffle. The baffle is integrally formed with the cover 2. The baffle surrounds to form a fastening groove that matches the top shape of the box body 1, so that the cover 2 can be accurately aligned and not easily shifted laterally when fastened. Upper grooves 4 are provided on the edge, corresponding to the lower grooves 3 one by one. Specifically, the upper grooves 4 are provided on the front and rear side walls of the edge. When the cover 2 is fastened to the box body 1, the lower grooves 3 and the upper grooves 4 are aligned to form a cavity 6 for the extension tube 14 to pass through and for limiting its position. Each cavity 6 separately accommodates a micro pump extension tube 14, limiting the extension tube 14 and preventing the tube from deviating. This eliminates the problem of multiple tubes crossing and tangling from a physical structure perspective.

[0035] The cover is detachably equipped with a label 5 for identifying the corresponding extension tube 14 at a position corresponding to each lumen 6, which is used to mark the name of the drug in the corresponding pipeline and other information, so as to achieve accurate classification and identification of one label per tube.

[0036] In a preferred embodiment, the cover 2 is made of a transparent material, specifically medical-grade transparent ABS or PC material. The label 5 has first magnets 7 at both ends, and the cover has second magnets 8 corresponding to the positions of the first magnets 7. The first magnets 7 and second magnets 8 can be magnetically connected, thus achieving a detachable connection between the label 5 and the cover. Using magnetic fixation, the label 5 can be removed and installed without tools, allowing for quick and easy removal or alignment by hand. This replacement efficiency is far higher than traditional adhesive tape methods, and it leaves no adhesive residue on the cover surface, facilitating daily cleaning and disinfection.

[0037] In some embodiments, the label 5 has a first fitting hole, and the first magnet 7 is fitted into the first fitting hole. Specifically, the first fitting hole is a blind hole structure, and the first magnet 7 is fitted and fixed in the first fitting hole by an interference fit. The outer surface of the first magnet 7 is flush with the surface of the label 5. The cover has a second fitting hole, and the second magnet 8 is fitted into the second fitting hole. Specifically, the second fitting hole is also a blind hole structure, and the second magnet 8 is fitted and fixed in the second fitting hole by an interference fit.

[0038] It should be noted that the installation position of the label 5 can be flexibly selected according to clinical use needs. It can be set on the front (top) of the cover or on the back of the cover (the side facing the inside of the box 1). Both arrangements are within the protection scope of this utility model.

[0039] When the label 5 is placed on the front of the cover, medical staff can directly read the drug information and remove the label 5 to modify the content without opening the cover 2. The operation is simple and suitable for clinical scenarios where drug labels are frequently checked and updated.

[0040] When the label 5 is placed on the back of the cover, the label 5 is located inside the cover, and the label content can be clearly read from the outside through the transparent cover. This arrangement prevents the label 5 from being directly exposed to the outside, avoids contamination of the label surface during clinical operations, and also reduces the problem of label displacement and detachment caused by external scratches. This is the preferred embodiment of the present invention.

[0041] Label 5 is an erasable label sheet made of erasable board material. Specifically, it can be made of medical-grade glossy PET erasable film or high-gloss acrylic board, with a dense, non-porous surface. When using it, medication information can be written on the label surface with a fine-tipped medical whiteboard marker; the writing is clear and eye-catching. When modification or updating information is needed, the writing can be completely erased with a dry erasing cloth, leaving no residue. The label sheet can be reused repeatedly. Compared to traditional paper label tape, erasable label sheets are waterproof, resistant to drug stains, less prone to curling and peeling, and have a longer service life.

[0042] In this embodiment, the lid 2 can be either a snap-on or flip-top design, with a flip-top structure being preferred. Specifically, one side of the lid 2 is hinged to the corresponding side of the box body 1 via a hinge; the lid 2 can be flipped open and closed around the hinge axis, opening the top opening of the box body 1, facilitating the batch deployment or adjustment of the extension tubes 14 by medical personnel. The other side of the lid 2 is magnetically attached to the corresponding side of the box body 1 via a magnetic attraction structure or by Velcro. When using a magnetic attraction structure, another set of magnets is embedded at corresponding positions on the lid and the box body 1, automatically engaging and locking when closed by magnetic force. As another alternative implementation, the snap-on connection between the lid 2 and the box body 1 can also be achieved using a Velcro structure. Specifically, a Velcro hook surface is horizontally attached to the lower surface of the free end of the lid, and a Velcro loop surface matching the hook surface is attached to the top surface of the corresponding side of the box body 1; when the lid 2 is snapped down to the closed position, the hook surface and the loop surface interlock and adhere to each other, thus achieving the locking and limiting of the lid 2 and the box body 1.

[0043] In some embodiments, the bottom surface of the box body 1 may also be provided with hook and loop fasteners or hooks for easy hanging.

[0044] The following is an example of how to use this device, using sticker 5 on the front: 1. Laying out the pipeline: Turn the cover 2 over and open it. Place the multiple micro-pump extension tubes 14 one by one into the lower grooves 3 of the box body 1, and straighten the axial direction of the pipeline.

[0045] 2. Fastening and limiting: The cover 2 is fastened downwards, and the upper groove 4 and the lower groove 3 are aligned to form an independent cavity 6, which separates and limits each extension tube 14 to prevent the pipeline from crossing and shifting.

[0046] 3. Labeling: Write the drug name and other information for the corresponding pipeline on the label 5, and attach it to the top of the corresponding cavity 6 on the cover by magnetic adsorption to complete the pipeline classification labeling.

[0047] 4. Updates and replacements: When the drug information needs to be adjusted, simply remove the label 5, erase and rewrite it, and then reset it; when the tubing needs to be replaced, open the cover 2, remove the old tubing, and insert the new tubing.

[0048] Technical benefits: This device forms independent cavities 6 by aligning the lower groove 3 and the upper groove 4, which separates and neatly arranges multiple micro-pump extension tubes 14, solving the problems of tangled and stacked tubes; at the same time, the label 5 is set one-to-one with the cavity 6, making the drug information intuitive and eye-catching, and medical staff can quickly locate the target tube, significantly shortening the tube identification time.

[0049] Example 2: like Figure 4 - Figure 9As shown, this embodiment is a further optimization based on Embodiment 1 and is a preferred embodiment of this utility model. It integrates functions such as anti-tangling and neat tubing, classification labeling, and 24-hour replacement timer reminder, which can fully implement the standardized operation of intravenous therapy nursing and reduce the risk of catheter-related bloodstream infections. Specifically: Based on the above embodiment, at least one first pipe clamp 9 and a second pipe clamp 10 are provided in the lower groove 3, and the first pipe clamp 9 and the second pipe clamp 10 are spaced apart along the axial direction. Among them, the second pipe clamp 10 is a conventional elastic open pipe clamp, which is used to assist in supporting the extension pipe 14, maintaining the axial straightness of the pipeline, avoiding bending, displacement or detachment of the pipeline, and ensuring unobstructed infusion passage.

[0050] The first tube clamp 9 is a dedicated tube clamp structure with circuit triggering function. The first tube clamp 9 includes a base 91, which is fixedly embedded in the bottom of the lower groove 3. The base 91 is provided with two oppositely arranged elastic claws 92, forming a clamping space between the two elastic claws 92. The first tube clamp 9 is embedded with a conductive sheet 93, and the two contact ends of the conductive sheet 93 extend to the outside of the two elastic claws 92 respectively. The inner wall of the lower groove 3 is provided with contact seats 15 at positions corresponding to the two contact ends. Under normal conditions, the elastic claws 92 are in a retracted state, the contact ends of the conductive sheet 93 are separated from the contact seats 15, and the circuit is in a disconnected state.

[0051] This embodiment also includes a sleeve 13 fitted onto the extension tube 14. The sleeve 13 is made of medical-grade rigid PVC or ABS material and has sufficient radial rigidity. When the extension tube 14 drives the sleeve 13 to be inserted into the first tube clamp 9, the sleeve 13 expands outward with two elastic claws 92, so that the two contact ends of the conductive sheet 93 respectively contact and conduct with the corresponding contact seat 15.

[0052] To facilitate operation, the sleeve 13 has a slot 131 cut along the axial direction on the tube wall to allow the extension tube 14 to pass through. Medical staff can use the slot 131 to laterally clamp the sleeve 13 onto the outer wall of the extension tube 14, completing the assembly without disconnecting the tubing or interrupting the infusion, which is fully compatible with existing clinical operating procedures.

[0053] Because the extension tube 14 of the micro-pump is a flexible medical tube with extremely low radial stiffness, if it is directly inserted between the elastic claws 92, the tube itself will undergo radial deformation, failing to provide sufficient spreading force to both sides to make the contacts conductive. The rigid sleeve 13, after being installed, moves synchronously with the extension tube 14. As a rigid force transmission component, it can convert the downward pressure of the tube into radial spreading force. When the extension tube 14 drives the sleeve 13 downward to be inserted between the two elastic claws 92, the rigid outer wall of the sleeve 13 expands the two elastic claws 92 outward, causing the contact end of the conductive piece 93 on the outside of the elastic claw 92 to move outward synchronously until it makes tight contact with the contact seat 15 on the groove wall, thus achieving reliable circuit conduction. When the extension tube 14 is pulled out, the sleeve 13 is removed along with the tube. After the elastic claws 92 lose external support, they automatically rebound due to their own elasticity, and the conductive piece 93 separates from the contact seat 15 again, and the circuit is immediately disconnected.

[0054] The bottom of the housing 1 has an installation cavity, and each lower groove 3 has an independent control module installed in the installation cavity. The operation of each control module is independent and does not interfere with each other, realizing independent control of "one module, one timer, and one alarm". The control module includes a power supply, a controller, and an audible and visual alarm 11. The conductive sheet 93 and the two contact seats 15 together form a switch, which is connected in series in the power supply circuit between the power supply and the controller. The controller is a mature commercially available component with a built-in 24-hour timer unit. The audible and visual alarm 11 is connected to the output terminal of the controller. When the conductive sheet 93 contacts the contact seat 15 and conducts electricity, the power supply circuit is closed, the controller is powered on and starts the 24-hour countdown. After the countdown ends, the controller controls the audible and visual alarm 11 to issue an alarm reminder.

[0055] The power supply circuit is connected as follows: the positive terminal of the power supply is connected to the power supply pin of the controller and the power supply terminal of the audible and visual alarm 11 in sequence via a wire, and finally connected to one of the contact bases 15; the negative terminal of the power supply is directly connected to the other contact base 15 via a wire. The two contact bases 15 are independent of each other and are normally in the open state. The conductive sheet 93 and the two contact bases 15 together form a trigger switch connected in series in the main power supply circuit.

[0056] When the two contact ends of the conductive sheet 93 make contact with the two contact seats 15 respectively, the positive terminal of the power supply, the controller, the audible and visual alarm 11, one side contact seat 15, the conductive sheet 93, the other side contact seat 15, and the negative terminal of the power supply form a complete closed circuit, and the entire control module is energized. The controller has a built-in timing unit, which automatically starts the preset 24-hour countdown program after being energized. After the countdown ends, the controller outputs a control signal to the audible and visual alarm 11 to trigger the light and sound alarm, prompting medical staff to replace the extension tube 14 in time.

[0057] As can be seen, this device uses the conductive plate 93 inside the first tube clamp 9 to cooperate with the contact seat 15 to form a trigger switch. After the extension tube 14 is installed in place, the power supply circuit automatically closes, triggering the controller to start a 24-hour countdown without additional operation. After the countdown ends, the audible and visual alarm 11 actively issues a replacement reminder, realizing independent control of "one tube, one timer, one alarm". This design eliminates the need for medical staff to manually record and remember the replacement time of each tube, effectively solving the problem of using the extension tube 14 beyond its expiration date in clinical work, ensuring strict implementation of intravenous therapy nursing operation standards, and reducing the risk of catheter-related bloodstream infections.

[0058] In some embodiments, the power supply uses a button cell battery or a lithium battery, with a preference for button cells, which are small in size and can provide long-term power to a single control module without the need for an external power cord.

[0059] The audible and visual alarm 11 includes an LED indicator and a buzzer. The controller has a built-in pre-reminder unit. When the countdown has a preset duration remaining, the controller controls the LED indicator to flash at a first frequency as a warning. After the countdown ends, the controller controls the LED indicator to flash at a second frequency and simultaneously activates the buzzer, with the second frequency being higher than the first frequency. Specifically, the controller has a built-in pre-reminder unit with tiered reminder logic: when the countdown has a preset duration remaining (e.g., 1 hour or 30 minutes), the controller controls the LED indicator to flash slowly at the first frequency to issue a warning, allowing medical staff to prepare replacement supplies in advance and rationally arrange their work schedule; when the 24-hour countdown ends, the controller controls the LED indicator to switch to a second frequency of rapid flashing and simultaneously activates the buzzer to emit an intermittent sound, with the second frequency being higher than the first frequency. The difference in flashing frequency distinguishes between warning and expiration alarm states, allowing medical staff to quickly determine the urgency of tubing replacement.

[0060] LED indicator lights can be embedded in the top edge of the corresponding lower groove 3, with their positions corresponding to the upper label 5; the buzzer is embedded inside the box 1, and the side wall of the box 1 has an array of sound holes corresponding to the position of the buzzer, which ensures that the reminder volume is clear while controlling the noise intensity, thus balancing the reminder effect with the quiet environment of the ward.

[0061] In some embodiments, the bottom of the housing 1 is also provided with a bottom cover 12 that fits the mounting cavity. The four corners of the bottom cover 12 are bolted to the housing 1 with screws to form a detachable sealed structure. The internal control module and battery can be inspected and replaced by removing the bottom cover 12, making subsequent maintenance convenient.

[0062] How to use: The specific operation flow of this embodiment is as follows: 1. Pre-installed rigid sleeve 13 Take a rigid sleeve 13 that is compatible with the extension tube 14, and cut an axial groove 131 along the side wall of the sleeve 13 to laterally clamp the sleeve 13 into the preset position of the extension tube 14. This operation does not require disconnecting the infusion passage and can be directly installed on the existing pipeline without affecting normal treatment.

[0063] 2. Lay out the pipeline and start the timing. Flip open the cover 2, and place the extension tubes 14 with rigid sleeves 13 one by one into the corresponding lower grooves 3. Align the sleeve 13 with the two elastic claws 92 of the first tube clamp 9 and press down to make the rigid sleeve 13 fully inserted and open the elastic claws 92 on both sides. At this time, the conductive sheet 93 contacts the contact seat 15 and conducts electricity. The power supply circuit of the corresponding control module is closed, and the controller automatically starts a 24-hour countdown. After the pipeline is laid out, close the cover 2 and lock it. Then, magnetically fix the label 5 with the drug information on the cover to the corresponding position to complete the entire laying operation.

[0064] 3. Routine inspections and early warning assessments During routine inspections, the identification information and LED indicator status can be directly viewed through the transparent cover: when the indicator is off or dimly lit at a low frequency, it indicates that the timer is running normally; when the indicator flashes slowly at the first frequency, it indicates that the corresponding extension tube 14 is about to be replaced, prompting medical staff to prepare replacement supplies in advance and arrange the work sequence reasonably.

[0065] 4. Replacement upon expiration and automatic reset When the 24-hour countdown for the corresponding extension tube 14 ends, the LED indicator switches to high-frequency rapid flashing, and the buzzer emits intermittent beeps as a reminder. Medical staff remove the expired extension tube 14; the elastic claw 92 automatically springs back to its original position, the conductive plate 93 separates from the contact seat 15, the control module is powered off, and it automatically resets to zero. After replacing the extension tube 14 with a new one and pre-installing the rigid sleeve 13, inserting the first tube clamp 9 according to the above steps will automatically start a new 24-hour countdown.

[0066] 5. Routine maintenance For routine disinfection, medical disinfectant can be used to wipe the outer surface of the device directly. When it is necessary to replace the battery or repair the internal circuit, unscrew the screws of the bottom cover 12 and remove the bottom cover 12 to replace and maintain the control module and button battery in the installation cavity. The operation is simple.

[0067] In summary: This device features a closable flip-top structure, facilitating easy tubing installation and removal. The label 5 is detachable and, with its erasable material, allows for rapid updates of medication information without the need for repeated tape application. Furthermore, each tubing has an independent control module, ensuring that individual tubing replacement and resetting do not interfere with each other. This significantly reduces the time spent on tubing organization and verification during shift changes, medication changes, and daily rounds, minimizing non-therapeutic procedures and improving clinical nursing efficiency. The device is compact, powered by an internal power supply, eliminating the need for external wiring, and can be flexibly installed on bed rails, infusion pump stands, and other locations. The sleeve 13 has an axial slot 131, allowing for fitting without disconnecting the tubing, and is compatible with existing clinical extension tube 14 usage habits. The installation cavity is equipped with a sealed bottom cover 12 to protect the internal circuitry, combining flexibility and operational reliability.

[0068] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
