Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a monitoring device for patient infusion safety. Background Art

[0002] Peripheral infusion is mainly to infuse drugs into the patient's blood through peripheral intravenous infusion, so as to achieve the effect of treating diseases. Common peripheral infusion is mainly to deliver multiple bottles of different drug solutions into the human body in sequence through intravenous drips.

[0003] During the intravenous infusion process, the infusion tube needs to be pulled out from the empty liquid bottle in time and reconnected with the infusion bottle filled with liquid medicine. If the infusion tube is not switched in time and the liquid medicine flows out, the blood in the infusion part of the patient will flow back into the infusion tube, causing a safety hazard to the patient. At present, there are devices on the market that monitor the weight of the infusion bottle and alarm to remind medical staff to switch the medicine bottle. For example, the patent with the prior art announcement number CN114470401A discloses an infusion device for clinical nursing that is easy to monitor. By setting a card block, a roller and a transmission belt, a structure similar to a fixed pulley is formed, which can automatically trigger the alarm. When the liquid medicine is lifted, the main force-bearing structure is the transmission belt, which is not easy to deform and is exposed on the outside of the structure, which is convenient for observing the damage. Even if it is deformed and elongated to a certain extent due to long-term use, it will not affect the automatic triggering mechanism. Compared with the spring, the reliability of the automatic triggering of the device is greatly improved.

[0004] However, the existing technology still has the following defects: although this technology can alarm the infusion bottle after the medicine is infused, the monitoring effect is poor. It lacks the function of limiting the flow of infusion. If the medical staff or caregivers fail to arrive in time to replace the infusion bottle, blood will still return to the patient's infusion site. Summary of the invention

[0005] In view of the problem that the prior art only provides a capacity reminder for an infusion bottle but lacks an active flow limiting function, a monitoring device for patient infusion safety is proposed.

[0006] Its purpose is to clamp and intercept the infusion tube after the drug delivery in the infusion bottle is completed, delay the drug delivery time, and ensure that medical staff or caregivers can replace the infusion bottle in time.

[0007] The technical solution of the present invention is a monitoring device for patient infusion safety, comprising a support frame, and also comprising a rotating frame installed at the upper end of the support frame, the rotating frame comprising a base fixedly connected to the support frame, the upper end of the base is rotatably connected to a rotating seat, a plurality of lifting rods are rotatably connected to the rotating seat, the end of the lifting rod away from the rotating seat is connected to a hanging member, and a cut-off mechanism is installed on the rotating frame; the cut-off mechanism comprises a driving component movably arranged inside the lifting rod, and a transmission component installed in the base, and also comprises a clamping assembly installed at the lower end of the base, and the driving component is used to drive the transmission component to move the clamping assembly The holding assembly clamps the infusion tube; the driving component includes a driving block movably connected to the inside of the lifting rod, and the driving block is fixedly connected to the driving rod on the side facing the base; the transmission component includes a rotating rod rotatably connected to the base, the upper end of the rotating rod abuts and cooperates with the driving rod, and the lower end of the rotating rod is transmission-connected with a T-shaped rod; the clamping assembly includes a bottom plate fixedly connected to the base, one end of the bottom plate is symmetrically structured and rotatably connected to two rotating plates, one end of the rotating plate is fixedly connected to a clamping plate, a spring is elastically connected between the two rotating plates, and one end of the T-shaped rod is used to limit the two rotating plates.

[0008] By adopting the above technical scheme, the hanging part is used to hang the infusion bottle, and a part of the infusion tube is arranged between the two clamping plates after being plugged into the infusion bottle. When the infusion bottle is full of liquid medicine, the end of the lifting rod away from the rotating seat tilts downward. As the liquid medicine in the infusion bottle gradually decreases, the end of the lifting rod away from the rotating seat rotates upward. When the liquid medicine in the infusion bottle is transported, the lifting rod is inclined at a certain angle, the driving block slides in the lifting rod and drives the rotating rod to rotate, the rotating rod drives the T-shaped rod to translate, the T-shaped rod cancels the limit on the two rotating plates, and drives the two clamping plates closer to each other under the pulling force of spring 1, clamps the infusion tube, makes the infusion channel of the infusion tube smaller, reduces the flow rate of the liquid medicine, thereby extending the transportation time of the remaining liquid medicine in the infusion tube.

[0009] Furthermore, the hanging member includes a sliding seat fixedly connected to the bottom of the lifting rod, a limiting plate is slidably connected inside the sliding seat, and a hook is fixedly connected to the bottom of the limiting plate; one end of the lifting rod passes through the rotating seat and is connected to a counterweight block.

[0010] By adopting the above technical solution, when the infusion bottle containing liquid medicine is not hung on the hook, the counterweight block causes the end of the lifting rod away from the rotating seat to tilt upward, and the movable limit plate can adjust the position of the hook so that it can be adjusted and adapted according to the size of the infusion bottle or the capacity of the liquid medicine. Therefore, when the infusion bottle containing liquid medicine is hung on the hook, the end of the lifting rod away from the rotating seat tilts downward.

[0011] Furthermore, the plurality of lifting rods are distributed in a ring-like shape with equal intervals, and the lifting rods are symmetrically rotatably connected with connecting plates on both sides, and the connecting plates are fixedly connected to the rotating seat, and a steering limit assembly is installed between the two connecting plates; the steering limit assembly includes a U-shaped rod rotatably connected to the two connecting plates, and the U-shaped rod is fixedly connected with tooth plates on both sides, and a ratchet is snap-fitted on one side of the tooth plate, and the ratchet is coaxially connected and fixed to the lifting rod.

[0012] By adopting the above technical solution, the U-shaped rod is in an inclined state so that the tooth plate abuts against the ratchet. When the weight of the infusion bottle gradually decreases, the end of the lifting rod away from the rotating seat gradually tilts upward, and the ratchet rotates counterclockwise synchronously with the lifting rod. The tooth plate limits the clockwise rotation of the ratchet, thereby preventing the lifting rod from being rotated by external force during the infusion process, avoiding affecting the judgment of the volume of the medicine in the infusion bottle.

[0013] Furthermore, rollers are rotatably connected at the corners on both sides of the driving block, and the rollers are in rolling contact with the inner wall of the lifting rod; an arc groove with an inferior arc structure is provided at the bottom of the driving block, and a limit block is slidably contacted in the arc groove, and a yielding inclined surface is provided on the limit block. The limit block is rotatably connected to the lifting rod, and a directional block is fixedly connected to the lower side of the limit block.

[0014] By adopting the above technical solution, a give-way slope is opened at the upper left part of the limit block. When the lifting rod rotates, the directional block keeps the limit block unchanged. When the inclination of the lifting rod is parallel to the give-way slope, the driving block can make the arc groove separate from the limit block under the action of gravity, move downward along the lifting rod, and make the driving rod hit the rotating rod.

[0015] Furthermore, a rotating column is fixedly connected to the lower end of the rotating rod, a tooth groove is opened on the rotating column, a gear is meshedly connected to the lower side of the tooth groove, a guide wheel is eccentrically connected to one side of the gear, and the guide wheel is slidably connected to the T-shaped rod; the rotating column and the gear are both rotatably connected to the base.

[0016] By adopting the above technical solution, the driving block moves along the inclined surface of the lifting rod so that the driving rod hits the rotating rod. The rotating rod rotates counterclockwise by a certain angle and drives the gear to rotate half a circle through the tooth groove. The guide wheel drives the T-shaped rod to move toward the end close to the base.

[0017] Furthermore, one end of the T-shaped rod is rotatably connected to two limiting wheels, and the limiting wheels are in rolling contact with a positioning block fixedly connected to the rotating plate; the T-shaped rod is slidably connected to the base plate, and a spring 2 is sleeved on the T-shaped rod, and the two ends of the spring 2 are respectively fixedly connected to the T-shaped rod and the base plate.

[0018] By adopting the above technical solution, after the T-shaped rod drives the limiting wheel to cancel the contact with the positioning block, the spring 1 makes the right ends of the two rotating plates approach each other under the action of tension, so that the two clamping plates cooperate to clamp the infusion tube, making the infusion tube channel smaller and the flow rate of the liquid medicine reduced.

[0019] Furthermore, the positioning block is in an L-shaped structure, and adjacent ends of two positioning blocks are abutted and matched.

[0020] By adopting the above technical solution, when the limiting wheel cancels the contact with the positioning block, the right ends of the two positioning blocks abut against each other, so that there is a certain distance between the two clamping plates, thereby preventing the two clamping plates from clamping the infusion tube too tightly, causing permanent deformation of the edge of the infusion tube and making it unable to recover, affecting the subsequent drug delivery.

[0021] Furthermore, a plurality of cut-off plates are fixedly connected to one side opposite to the two clamping plates, the plurality of cut-off plates are vertically staggered, and a bundle of pipes is fixedly connected to the clamping plates, the bundle of pipes is in a J-shaped structure.

[0022] By adopting the above technical solution, one of the bundled tube members is connected to the upper side of the clamping plate, and the other bundled tube member is connected to the lower side of the clamping plate, and the infusion tube is arranged between the two bundled tube members, so that the clamping plates can accurately clamp the infusion tube when they are close to each other. When the two clamping plates cooperate to clamp the infusion tube, the intercepting plates of the two clamping plates make the clamped part of the infusion tube form an S-shaped channel, thereby increasing the flow path of the liquid medicine and further extending the flow time of the liquid medicine.

[0023] Furthermore, a plurality of clearance grooves are provided on both sides of the clamping plate, guide rods are hinged in the clearance grooves, and guide blocks are fixedly connected in the clearance grooves, and the guide rods are in sliding contact with the guide blocks adjacent to the guide rods in the transverse direction.

[0024] By adopting the above technical scheme, when the infusion tube is deformed by the clamping plate, the infusion tube located in the make way groove part is not affected by the clamping plate so that the deformation degree is small, and after the guide rod slides in contact with the guide block laterally adjacent, the guide rods on both sides of the infusion tube apply a force perpendicular to the clamping plate to the infusion tube, which can further reduce the deformation degree of the infusion tube located in the make way groove part, which is beneficial to the automatic recovery of the infusion tube after the clamping plate cancels the clamping of the infusion tube.

[0025] Furthermore, an alarm unit is installed on the rotating frame, and the alarm unit includes a contact piece 1 fixedly connected to the inner wall of the base, a contact piece 2 fixedly connected to the bottom of the counterweight block, and a buzzer fixedly connected to the top of the rotating seat.

[0026] By adopting the above technical solution, when the liquid medicine in the infusion bottle is delivered, the end of the lifting rod away from the rotating seat rotates upward, and the counterweight block descends, driving the contact piece 2 to contact with the contact piece to trigger the switch of the buzzer. At this time, the buzzer can emit a sound reminder to change the liquid.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. When the liquid medicine in the infusion tube is delivered, the end of the lifting rod away from the rotating seat tilts upward, the counterweight block drops to make the alarm unit sound an alarm, and at the same time the driving block slides downward and hits the rotating rod, so that the limit wheel cancels the contact with the positioning block. The two rotating plates approach each other under the action of spring 1, clamping the infusion tube, making the infusion tube channel smaller and the flow rate of the liquid medicine reduced, thereby extending the delivery time of the liquid medicine in the infusion tube and ensuring that medical staff or caregivers can replace the infusion bottle in time.

[0029] 2. The two clamping plates cooperate with the intercepting plate to form an S-shaped channel in the clamped part of the infusion tube, thereby increasing the flow path of the liquid medicine, further extending the flow time of the liquid medicine, and increasing the liquid replacement time.

[0030] 3. The infusion tube located in the make way groove is not affected by the clamping plate, so the deformation degree is small. After the guide rod contacts the guide block, the guide rods on both sides of the infusion tube apply a force perpendicular to the clamping plate to the infusion tube, which can further reduce the deformation degree of the infusion tube located in the make way groove, which is beneficial to the automatic recovery of the infusion tube after the clamping plate cancels the clamping of the infusion tube, ensuring that the normal infusion speed of the infusion tube is not affected.

[0031] 4. By setting up the alarm unit, the lifting rod gradually rotates with the weight of the infusion bottle. When the contact piece 1 contacts the contact piece 2, the buzzer alarm is triggered to remind the infused patient. At the same time, an infusion replacement reminder is sent to the nurse station to remind the medical staff on duty to replace the infusion bottle in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0047] Example 1, reference Figure 1-Figure 10, which is the first embodiment of the present invention, provides a monitoring device for patient infusion safety, including a support frame 1, and also includes a rotating frame 2 installed on the upper end of the support frame 1, the rotating frame 2 includes a base 21 fixedly connected to the support frame 1, the upper end of the base 21 is rotatably connected to a rotating seat 22, and a plurality of lifting rods 23 are rotatably connected to the rotating seat 22, and the lifting rod 23 is connected to a hanging member 24 at one end away from the rotating seat 22, and a cut-off mechanism is installed on the rotating frame 2; the cut-off mechanism includes a driving component 4 movably arranged inside the lifting rod 23, and a transmission component 5 installed in the base 21, and also includes a clamping assembly 6 installed at the lower end of the base 21, and the driving component 4 is used to drive the transmission component 5 to move so that the clamping assembly The component 6 clamps the infusion tube; the driving component 4 includes a driving block 41 movably connected to the inside of the lifting rod 23, and the driving block 41 is fixedly connected to the driving rod 42 on the side facing the base 21; the transmission component 5 includes a rotating rod 51 rotatably connected to the base 21, the upper end of the rotating rod 51 abuts and cooperates with the driving rod 42, and the lower end of the rotating rod 51 is transmission-connected to a T-shaped rod 54; the clamping component 6 includes a bottom plate 61 fixedly connected to the base 21, one end of the bottom plate 61 is symmetrically structured and rotatably connected to two rotating plates 62, one end of the rotating plate 62 is fixedly connected to a clamping plate 63, a spring 64 is elastically connected between the two rotating plates 62, and one end of the T-shaped rod 54 is used to limit the two rotating plates 62.

[0048] Specifically, the hanging member 24 is used to hang the infusion bottle. After the infusion tube is connected to the infusion bottle, a part of it is arranged between the two clamping plates 63. When the infusion bottle is full of liquid medicine, the end of the lifting rod 23 away from the rotating seat 22 tilts downward. As the liquid medicine in the infusion bottle gradually decreases, the end of the lifting rod 23 away from the rotating seat 22 rotates upward. When the liquid medicine in the infusion bottle is transported, the lifting rod 23 is inclined at a certain angle, and the driving block 41 slides in the lifting rod 23 and drives the rotating rod 51 to rotate. The rotating rod 51 drives the T-shaped rod 54 to translate. The T-shaped rod 54 cancels the limit on the two rotating plates 62, and drives the two clamping plates 63 to approach each other under the pulling force of the spring 64, clamps the infusion tube, makes the infusion channel of the infusion tube smaller, reduces the flow rate of the liquid medicine, and thereby prolongs the transportation time of the remaining liquid medicine in the infusion tube.

[0049] Reference Figure 3-Figure 4 The hanging member 24 includes a sliding seat 241 fixedly connected to the bottom of the lifting rod 23, a limiting plate 242 is slidably connected inside the sliding seat 241, and a hook 243 is fixedly connected to the bottom of the limiting plate 242; one end of the lifting rod 23 passes through the rotating seat 22 and is connected to a counterweight block 25.

[0050] Specifically, when an infusion bottle containing liquid medicine is not hung on the hook 243, the counterweight 25 causes the end of the lifting rod 23 away from the rotating seat 22 to tilt upward, and the movable limit plate 242 can adjust the position of the hook 243 so that it can be adjusted and adapted according to the size of the infusion bottle or the capacity of the liquid medicine. Therefore, when the infusion bottle containing liquid medicine is hung on the hook 243, the end of the lifting rod 23 away from the rotating seat 22 tilts downward.

[0051] Among them, refer to Figure 4 The bottom surface of the limit plate 242 and the slide 241 are both provided with card slots, and the limit plate 242 is connected to the slide 241 through the card slots to prevent the limit plate 242 from moving arbitrarily, and the bottom surface of the slide 241 is engraved with millimeter scales, and a pointer is fixedly connected to the hook 243. Through the cooperation of the pointer and the scale, the hook 243 can be adjusted in direction according to the weight of the mount.

[0052] Reference Figure 3 , Figure 5 , multiple lifting rods 23 are distributed in a ring shape with equal intervals, and the lifting rods 23 are symmetrically connected to the connecting plates 26 on both sides, and the connecting plates 26 are fixedly connected to the rotating seat 22, and a steering limit assembly 3 is installed between the two connecting plates 26; the steering limit assembly 3 includes a U-shaped rod 31 rotatably connected to the two connecting plates 26, and the U-shaped rod 31 has tooth plates 32 fixedly connected on both sides, and a ratchet 33 is snap-fitted on one side of the tooth plate 32, and the ratchet 33 is coaxially connected and fixed to the lifting rod 23.

[0053] Specifically, the U-shaped rod 31 is in an inclined state so that the tooth plate 32 abuts against the ratchet 33. When the weight of the infusion bottle gradually decreases, the end of the lifting rod 23 away from the rotating seat 22 gradually tilts upward, and the ratchet 33 rotates counterclockwise synchronously with the lifting rod 23. The tooth plate 32 restricts the clockwise rotation of the ratchet 33, thereby preventing the lifting rod 23 from being rotated by external force during the infusion process, thereby avoiding affecting the judgment of the volume of the liquid in the infusion bottle.

[0054] It can be understood that when the lifting rod 23 needs to be restored, the lifting rod 23 can be automatically rotated by pushing the U-shaped rod 31 to the left to drive the tooth plate 32 to cancel the contact with the ratchet 33. In addition, a baffle rod fixedly connected to the connecting plate 26 is provided on the left side of the U-shaped rod 31. The baffle rod limits the rotation of the U-shaped rod 31, so that the U-shaped rod 31 is always tilted to the right to drive the tooth plate 32 to contact the ratchet 33.

[0055] Reference Figure 6-Figure 7 The corners on both sides of the driving block 41 are rotatably connected with rollers 43, and the rollers 43 are in rolling contact with the inner wall of the lifting rod 23; an arc groove 44 with a inferior arc structure is provided at the bottom of the driving block 41, and a limit block 45 is in sliding contact in the arc groove 44. A yielding inclined surface 46 is provided on the limit block 45. The limit block 45 is rotatably connected to the lifting rod 23, and a directional block 47 is fixedly connected to the lower side of the limit block 45.

[0056] Specifically, the yield slope 46 is opened at the upper left part of the limit block 45, and when the lifting rod 23 rotates, the orienting block 47 keeps the limit block 45 unchanged. When the inclination of the lifting rod 23 is parallel to the yield slope 46, the driving block 41 can make the arc groove 44 separate from the limit block 45 under the action of gravity, move downward along the lifting rod 23, and make the driving rod 42 hit the rotating rod 51.

[0057] Among them, the angle between the give-way slope 46 and the horizontal line is any degree between 10° and 30°. When the inclination angle of the lifting rod 23 is parallel to the slope angle of the give-way slope 46, the give-way slope 46 faces the arc groove 44, so that the limit block 45 does not contact the driving block 41, and the driving block 41 can move through the roller 43 under the action of gravity.

[0058] Reference Figure 2 , Figure 7 , Figure 8 The lower end of the rotating rod 51 is fixedly connected to a rotating column 52, a tooth groove 53 is opened on the rotating column 52, a gear 56 is meshed and connected to the lower side of the tooth groove 53, a guide wheel 57 is eccentrically connected to one side of the gear 56, and the guide wheel 57 is slidably connected to the T-shaped rod 54; the rotating column 52 and the gear 56 are both rotatably connected to the base 21.

[0059] Specifically, the driving block 41 moves along the inclined surface of the lifting rod 23 to make the driving rod 42 hit the rotating rod 51, and the rotating rod 51 rotates counterclockwise by a certain angle and drives the gear 56 to rotate half a circle through the tooth groove 53, and the guide wheel 57 drives the T-shaped rod 54 to move toward the end close to the base 21.

[0060] Reference Figure 8-Figure 9 One end of the T-shaped rod 54 is rotatably connected to two limiting wheels 55, and the limiting wheels 55 are in rolling contact with the positioning blocks 65 fixedly connected to the rotating plate 62; the T-shaped rod 54 is slidably connected to the bottom plate 61, and a spring 2 58 is sleeved on the T-shaped rod 54, and the two ends of the spring 2 58 are respectively connected and fixed to the T-shaped rod 54 and the bottom plate 61.

[0061] Specifically, after the T-bar 54 drives the limiting wheel 55 to cancel the contact with the positioning block 65, the spring 1 64 pulls the right ends of the two rotating plates 62 closer to each other under the action of tension, so that the two clamping plates 63 cooperate to clamp the infusion tube, making the infusion tube channel smaller and the flow rate of the liquid medicine reduced.

[0062] It can be understood that when the guide wheel 57 drives the T-shaped rod 54 to move, the spring 2 58 is compressed and stores force. When the left parts of the two rotating plates 62 approach each other and the two positioning blocks 65 move away from each other, the spring 2 58 can drive the T-shaped rod 54 to move in the opposite direction, so that the guide wheel 57 is reset in the positioning block 65.

[0063] Reference Fig.10The positioning block 65 is in an L-shaped structure, and the adjacent ends of the two positioning blocks 65 are abutted and matched.

[0064] Specifically, when the limiting wheel 55 cancels the contact with the positioning block 65, the right ends of the two positioning blocks 65 abut against each other, so that there is a certain distance between the two clamping plates 63, thereby preventing the two clamping plates 63 from clamping the infusion tube too tightly, causing permanent deformation of the edge of the infusion tube and making it unable to recover, affecting the subsequent delivery of the drug solution.

[0065] Reference Fig.11 A plurality of intercepting plates 66 are fixedly connected to one side opposite to the two clamping plates 63 . The plurality of intercepting plates 66 are vertically staggered. A pipe bundle 7 is fixedly connected to the clamping plates 63 . The pipe bundle 7 is in a J-shaped structure.

[0066] Specifically, one of the bundled tube members 7 is connected to the upper side of the clamping plate 63, and the other bundled tube member 7 is connected to the lower side of the clamping plate 63. The infusion tube is arranged between the two bundled tube members 7, so that the clamping plates 63 can accurately clamp the infusion tube when they are close to each other. When the two clamping plates 63 cooperate to clamp the infusion tube, the intercepting plates 66 of the two clamping plates 63 form an S-shaped channel at the clamped part of the infusion tube, thereby increasing the flow path of the liquid medicine and further extending the flow time of the liquid medicine.

[0067] Example 2, reference Fig.11 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a plurality of clearance grooves 67 are provided on both sides of the clamping plate 63, a guide rod 68 is hinged in the clearance groove 67, and a guide block 69 is fixedly connected in the clearance groove 67, and the guide rod 68 is in sliding contact with the guide block 69 which is adjacent to the guide block 69 in the transverse direction.

[0068] Specifically, when the infusion tube is deformed by the clamping plate 63, the infusion tube located in the clearance groove 67 is not affected by the clamping plate 63, so the deformation degree is small, and after the guide rod 68 slides and contacts with the guide block 69 adjacent to the horizontal direction, the guide rods 68 on both sides of the infusion tube apply a force perpendicular to the clamping plate 63 to the infusion tube, which can further reduce the deformation degree of the infusion tube located in the clearance groove 67, which is conducive to the automatic recovery of the infusion tube after the clamping plate 63 cancels the clamping of the infusion tube. The rest of the structure is the same as that of the first embodiment.

[0069] Example 3, reference Figure 2-Figure 3 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that an alarm unit 8 is installed on the rotating frame 2, and the alarm unit 8 includes a contact piece 1 81 fixedly connected to the inner wall of the base 21, and a contact piece 2 82 fixedly connected to the bottom of the counterweight block 25, and also includes a buzzer 83 fixedly connected to the top of the rotating base 22.

[0070] Specifically, when the liquid medicine in the infusion bottle is delivered, the end of the lifting rod 23 away from the rotating seat 22 rotates upward, and the counterweight block 25 descends, driving the contact piece 2 82 to contact the contact piece 1 81 to trigger the switch of the buzzer 83. At this time, the buzzer 83 can emit a sound reminder to change the liquid.

[0071] Among them, a flash light is also installed at one end of the lifting rod 23. When the contact piece 2 82 at the end of one of the lifting rods 23 is connected to the contact piece 1 81, the flash light connected to the lifting rod 23 flashes, allowing medical staff to quickly know the location where the infusion bottle needs to be replaced.

[0072] It is understandable that, referring to Figure 3 and Fig.12 A protective cover is fixedly installed on the top of the rotating seat 22, a buzzer 83 is arranged in the protective cover, and a central processing unit and a power supply are also arranged in the protective cover. The central processing unit is used to coordinate the work of various components, and the power supply is used to provide electrical energy to the components. When the contact piece 2 82 contacts the contact piece 1 81, the circuit is closed to form a loop, and the central processing unit receives the current change signal and controls the buzzer 83 to emit an alarm sound reminder. The rest of the structure is the same as that of Example 2.

[0073] Example 4, reference Figure 3 and Fig.12 The alarm unit 8 also includes a background management platform, a wireless communication module, and a receiving terminal. The wireless communication module is arranged in a protective cover and connected to the central processor signal. The background management platform interacts with the wireless communication module and the receiving terminal through wireless signals. The background management platform marks each infusion stand. Each infusion stand can be customized with a number and location information, and is displayed in real time on the background management platform, which is convenient for locating the infusion stand. At the same time, the infusion stand can be bound to the patient information currently using the infusion stand. The background management platform can display the patient name, location, and infusion information corresponding to the infusion stand. Multiple infusion stands are divided into zones according to hospital areas or floors, and each zone corresponds to multiple responsible nurses. The receiving terminal is a nurse's mobile phone. The process is as follows:

[0074] Infusion monitoring: The contact piece 2 82 cooperates with the contact piece 1 81 to monitor the remaining flow in the infusion bottle;

[0075] Low liquid volume warning: When the contact piece 2 82 contacts the contact piece 1 81, the central processing unit controls the buzzer 83 to sound an alarm, and at the same time, the central processing unit controls the wireless communication module to send a warning signal (including patient information, infusion position, infusion information, etc.) to the background management platform;

[0076] Backstage processing: The backstage management platform receives warning signals and performs data processing and analysis. The platform automatically generates fluid change reminder information based on preset rules and sends it to the mobile phone of the nurse in charge on duty via SMS, APP push, etc.

[0077] Nurse response: After receiving the fluid change reminder, the nurse will go to the patient's bed in time to perform the fluid change operation. After the fluid change is completed, the nurse can send the fluid change completion confirmation information to the backend management platform through the mobile phone APP or the confirmation button on the infusion stand;

[0078] Record update: After receiving the confirmation information, the background management platform updates the patient's infusion record and marks the completion of the fluid change. At the same time, the background system can generate relevant statistical reports to facilitate hospital management and analysis. The rest of the structure is the same as that of Example 3.

[0079] In summary, the working principle of the present invention is as follows: a plurality of infusion bottles are hung on the hooks 243 of each lifting rod 23, respectively. At this time, the gravity of the end of the lifting rod 23 away from the rotating seat 22 is greater than that of the other end, so that the end of the lifting rod 23 away from the rotating seat 22 is tilted downward, and the infusion tube is plugged into the infusion bottle located on the upper side of the clamping assembly 6, and the infusion tube is connected to the two bundle pipe pieces 7. As the liquid medicine in the infusion bottle gradually decreases, the end of the lifting rod 23 away from the rotating seat 22 rotates downward. When the liquid medicine in the infusion bottle is delivered, the tilt angle of the lifting rod 23 is parallel to the inclined surface of the yielding inclined surface 46, and the driving block 41 slides downward in the lifting rod 23 and causes the driving rod 42 to hit the rotating rod 51, the rotating column 52 rotates to make the tooth groove 53 drive the gear 56 to rotate half a circle, and the guide wheel 57 drives the T-shaped rod 54 to move to the end close to the base 21. After the T-shaped rod 54 drives the limiting wheel 55 to cancel the contact with the positioning block 65, the spring 1 64 makes the right ends of the two rotating plates 62 approach each other under the action of tension, so that the two clamping plates 63 and the intercepting plate 66 cooperate to clamp the infusion tube, making the infusion tube channel smaller and the flow rate of the liquid medicine reduced. At the same time, the counterweight block 25 descends to drive the contact piece 2 82 to contact the contact piece 1 81 to trigger the switch of the buzzer 83. At this time, the buzzer 83 can emit a sound reminder for changing the liquid, and the flash light at the end of the lifting rod 23 flashes for prompting.

[0080] After the infusion tube is disconnected from the current infusion bottle, the rotating seat 22 can be rotated to place the next infusion bottle filled with liquid medicine above the clamping assembly 6, and the infusion tube is reconnected to the infusion bottle to continue the infusion operation.

[0081] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
