Description

Technical Field

[0001] This invention relates to the field of hospital monitoring technology, specifically to an infusion stand. Background Technology

[0002] Intravenous infusion, also known as drip infusion or IV drip, is a large-dose injection of intravenous fluids. It is usually packaged in glass or plastic infusion bottles or bags and does not contain preservatives or antibacterial agents. When used, the drip rate is adjusted by the infusion set to continuously and stably enter the vein to replenish body fluids, electrolytes or provide nutrients. Hospital patients often need to receive intravenous infusions in their wards to treat their conditions.

[0003] Chinese invention patent CN202011201726.3 discloses a hospital patient monitoring alarm device and system, including a support frame placed next to a hospital bed. Multiple sorting racks are fixedly connected to the top of the support frame. The sides of the sorting racks have mounting grooves, and vertically arranged mounting rods are fixedly connected to the inner walls of the mounting grooves. Sliding blocks are slidably connected to the inner walls of the mounting rods, and mounting springs are sleeved on the outer walls of the mounting rods. The two ends of the mounting springs are fixedly connected to the top of the sliding blocks and the side walls of the mounting grooves, respectively. A mounting plate is fixedly connected to the side of the sliding blocks, and an IV drip bottle is connected to the bottom of the mounting plate via a hook. This device requires sorting the IV drip bottles during use, suspending different bottles on their corresponding sorting racks. However, if a patient needs multiple IV drips of different weights, multiple sorting racks are required, making it inconvenient to use. Furthermore, during IV infusions, especially in cold weather, the low temperature of the medication can irritate the body. If the medication is irritating, the patient may experience stinging, affecting their medical experience.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an infusion stand that has the advantages of automatically calling medical staff, being suitable for different IV drips with one stand, and creating a temperature-appropriate space for the patient's arm. It solves the problems of using different sorting stands for IV drips of different weights and the stinging sensation experienced by patients in cold weather or when the medication is irritating.

[0006] To address the technical problems of using different sorting racks for IV drips of varying weights and the stinging sensation experienced by patients in cold weather or due to medication irritation, this invention provides the following technical solution: an IV stand, comprising an IV support, with a fixing box at the upper end of the IV support. Inside the fixing box, on both sides of the IV support, are respectively arranged a linkage mechanism and a suspension mechanism. A pressure sensor is installed inside the linkage mechanism. When the pressure sensor reaches a threshold force, it transmits a signal to a main controller. The main controller is located at the nurses' station, controlling an alarm to sound and displaying the bed number on a screen. Nurses then proceed to the ward according to the bed number to change the IV fluid for the patient. A support mechanism is provided through one side of the IV stand to support the patient's arm.

[0007] Preferably, the infusion stand has a first through hole on its side, and the support mechanism is disposed through the first through hole. The support mechanism includes a first screw, and a driving member and a support block are respectively fixedly disposed at both ends of the first screw. The driving member is used to drive the first screw to rotate, and the support block is used to fix the first screw. A first connecting block is threadedly connected to the middle of the first screw. The first connecting block is disposed through the first through hole and extends to the outside of the infusion stand. A support platform is fixedly connected to the end of the first connecting block located on the outside of the infusion stand, and a heating mechanism is snapped onto the support platform.

[0008] Preferably, the support platform has T-shaped slots at both ends of its upper and lower surfaces. The heating mechanism is engaged in the T-shaped slots. The heating mechanism includes T-shaped blocks that are engaged in the T-shaped slots. A semi-cylindrical container is fixedly connected between the two T-shaped blocks. The semi-cylindrical container has an inner cavity. A container lid is fixedly mounted on the semi-cylindrical container and is connected to the inner cavity of the semi-cylindrical container. The upper part of the container lid is detachably mounted on the lid. Hot water is poured into the inner cavity of the semi-cylindrical container from the container lid. The heat emitted by the hot water is transferred outward through the wall of the semi-cylindrical container to heat the patient's arm.

[0009] Preferably, the suspension mechanism includes a spring, the upper end of which is fixedly connected to the fixing box, and the lower end of which is fixedly connected to a circular plate. A first hook is fixedly provided on the lower surface of the circular plate for suspending the IV drip. Several telescopic rods are evenly arranged on the upper surface of the circular plate outside the spring. The upper ends of the telescopic rods are fixedly connected to the fixing box. The IV drip is suspended by the first hook. As the amount of medicine in the IV drip gradually decreases, the length of the spring gradually shortens, causing the circular plate and the first hook to gradually rise.

[0010] Preferably, a second connecting block is fixedly disposed on the side of the circular plate near the infusion support, and the linkage mechanism is rotatably connected inside the second connecting block. The linkage mechanism is used to change the positional relationship between the pressure sensor and the circular plate.

[0011] Preferably, the linkage mechanism includes a first connecting rod, and second through holes are provided on both sides of the infusion support. The first connecting rod is disposed through the second through hole. A third connecting block is rotatably connected to the end of the first connecting rod away from the second connecting block. A second screw is threadedly connected to the third connecting block. The two ends of the second screw are rotatably connected to the infusion support and the fixing box, respectively.

[0012] Preferably, a second connecting rod is rotatably connected to the upper part of the second screw, and a fourth connecting block is rotatably connected to the end of the second connecting rod away from the second screw. A third screw is threadedly connected to the fourth connecting block, and the two ends of the third screw are rotatably connected to the infusion bracket and the fixing box, respectively. A support rod is fixedly connected to one side of the fourth connecting block, and the pressure sensor is disposed at the end of the support rod away from the fourth connecting block. The support rod is slidably sleeved in the infusion bracket, and when the fourth connecting block is closest to the infusion bracket, the support rod can extend to the other side of the infusion bracket.

[0013] Preferably, the infusion stand is fixedly provided with a button and a second hook on its side. The button is used to activate the drive unit, and the second hook is used to suspend the remaining medication of the patient.

[0014] Beneficial effects

[0015] 1. By incorporating a pressure sensor, when the IV drip reaches its highest point, the pressure sensor inside the linkage mechanism presses against the upper surface of the circular plate, exceeding a threshold. The pressure sensor then transmits a signal to the main controller, which activates the alarm and displays the bed number on the screen. The nurse then proceeds to the corresponding ward to change the IV fluid. This system monitors the patient's IV infusion process using a pressure sensor, eliminating the need for the patient to call for a nurse. It also allows nurses to easily change dressings at appropriate times, simplifying their work.

[0016] 2. By setting up a heating mechanism, a heating mechanism filled with hot water at a suitable temperature is attached to the upper part of the support platform to heat the air inside the heating mechanism, creating a suitable temperature space for the patient's arm, reducing the stinging sensation during infusion, and improving the patient's medical experience. In addition, when used in conjunction with the support mechanism, it can prevent the patient's arm from falling off during infusion and causing danger.

[0017] 3. By setting up a linkage mechanism and a suspension mechanism, and connecting the two, the position between the pressure sensor and the circular plate is controlled by the gravity of the suspended bottle, so that the pressure sensor transmits signals at the appropriate time.

[0018] 4. By setting up multiple hooks, nurses can hang all of the patient's medications on the infusion stand before the infusion begins. Then, when changing the medications, nurses no longer need to carry the medications from the nurses' station. This makes it easier for nurses to work and avoids confusion caused by too many medications at the nurses' station.

[0019] In summary, this application utilizes the gravitational change caused by the reduction of the infusion solution as the driving force. Through a mechanical linkage mechanism, the minute vertical displacement is converted into lateral displacement, automatically triggering the pressure sensor alarm. This achieves automatic monitoring of the infusion process without the need for an external power source, solving the technical problems of continuous power consumption and short battery life in traditional electronic infusion monitoring devices. Simultaneously, this linkage mechanism works in conjunction with the support and heating mechanisms to automatically provide support and protection for the patient's arm when an alarm is triggered, preventing arm displacement and needle dislodgement risks caused by the patient getting up to check the IV drip.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-7 An infusion stand includes an infusion stand 1, with a fixing box 12 at the upper end of the infusion stand 1. Inside the fixing box 12, a linkage mechanism and a suspension mechanism are respectively arranged on both sides of the infusion stand 1. A pressure sensor 26 is installed inside the linkage mechanism. When the pressure sensor 26 reaches a threshold force, it transmits a signal to the host controller. The host controller is located at the nurse station. The host controller controls the alarm to sound and displays the bed number on the display screen. The nurse goes to the ward according to the bed number to change the patient's medication. A support mechanism is installed through one side of the infusion stand 1 to support the patient's arm.

[0024] Furthermore, the infusion stand 1 has a first through hole 2 on its side, and a support mechanism is disposed through the first through hole 2. The support mechanism includes a first screw 4, with a driving component 3 and a support block 5 fixedly disposed at both ends of the first screw 4, respectively. The driving component 3 is used to drive the first screw 4 to rotate, and the driving component 3 is a servo motor, which can drive the first screw 4 to rotate clockwise or counterclockwise. The support block 5 is fixedly disposed inside the infusion stand 1 to fix the first screw 4. A first connecting block 6 is threadedly connected to the middle of the first screw 4. The first connecting block 6 is disposed through the first through hole 2 and extends to the outside of the infusion stand 1, and the width of the first connecting block 6 is equal to the width of the first through hole 2. The connecting block 6 is fixedly connected to the support platform 7 at the outer end of the infusion stand 1. A heating mechanism is snapped onto the support platform 7. In specific applications, the drive component 3 is first opened, and the drive component 3 drives the first screw 4 to rotate. Since the first connecting block 6 is threadedly connected to the first screw 4, the first connecting block 6 moves vertically upward or downward during the rotation of the first screw 4, thereby driving the support platform 7 to move vertically upward or downward. Once it moves to the height of the patient, the drive component 3 can be closed. Then, the patient can place their arm on it for infusion. The support mechanism supports the patient's arm, and there is a heating mechanism on the side to prevent the patient's arm from falling off during infusion and causing danger.

[0025] Furthermore, T-shaped slots 8 are provided at both ends of the upper and lower surfaces of the support platform 7. The heating mechanism is engaged in the T-shaped slots 8. The heating mechanism includes T-shaped blocks 9, which are engaged inside the T-shaped slots 8. A semi-cylindrical container 10 is fixedly connected between the two T-shaped blocks 9. The semi-cylindrical container 10 has an inner cavity, and a container lid 11 is fixedly installed on the semi-cylindrical container 10. The container lid 11 is connected to the inner cavity of the semi-cylindrical container 10. The upper part of the container lid 11 is detachably equipped with a lid. Hot water is poured into the inner cavity of the semi-cylindrical container 10 from the container lid 11. The heat emitted by the hot water is transferred outward through the wall of the semi-cylindrical container 10 to heat the patient's arm, especially during intravenous infusion, in cold weather. In some cases, the temperature of the medication is low, which can cause some irritation to the body after entering the body. If the medication is irritating, the patient will experience a stinging sensation. In this case, it is necessary to heat the patient's arm to reduce the stinging sensation. Before the infusion, the heating mechanism is engaged in the T-shaped slot 8 on the lower surface of the support platform 7. Then, the heating mechanism is removed, the cover is opened, and hot water of a suitable temperature is injected into the inner cavity of the semi-cylindrical container 10 from the container cover 11. After that, the cover is closed, and the heating mechanism is engaged in the T-shaped slot 8 on the upper surface of the support platform 7. At this time, the heating mechanism is located on the upper part of the patient's arm, heating the air inside the heating mechanism to create a suitable temperature space for the patient's arm, reducing the stinging sensation during the infusion and improving the patient's medical experience.

[0026] Furthermore, the suspension mechanism includes a spring 13, the upper end of which is fixedly connected to the fixed box 12, and the lower end of which is fixedly connected to a circular plate 14. A first hook 15 is fixedly provided on the lower surface of the circular plate 14 for suspending the IV drip. Several telescopic rods 16 are evenly provided on the upper surface of the circular plate 14 outside the spring 13. The upper ends of the telescopic rods 16 are fixedly connected to the fixed box 12. First, the IV drip is suspended on the first hook 15. Since there is a certain amount of liquid in the IV drip, the spring 13 is pulled down by gravity. The spring 13 is deformed by the force and its length is extended. It has a reaction force on both the fixed box 12 and the circular plate 14. As the infusion time increases, the amount of medicine in the IV drip gradually decreases, that is, the downward pulling force on the spring 13 gradually decreases. As a result, the length of the spring 13 gradually shortens under the action of the reaction force, thereby driving the circular plate 14 and the first hook 15 to gradually rise. In addition, telescopic rods 16 are also provided on the outside of the spring 13 to ensure that the IV drip moves in the vertical direction during the up and down movement.

[0027] Furthermore, a second connecting block 17 is fixedly installed on the side of the circular plate 14 near the infusion stand 1. A linkage mechanism is rotatably connected within the second connecting block 17. This linkage mechanism changes the positional relationship between the pressure sensor 26 and the circular plate 14, so that when the IV drip reaches its highest point, the pressure sensor 26 inside the linkage mechanism presses against the upper surface of the circular plate 14 beyond a threshold. The pressure sensor 26 then transmits a signal to the main controller, which activates the alarm and displays the bed number on the screen. The nurse then proceeds to the corresponding ward to change the IV fluid according to the displayed bed number. This system uses the pressure sensor 26 to monitor the patient's IV infusion process without requiring the patient to call for a nurse, and it also allows nurses to conveniently go to the ward to change the medication at appropriate times, simplifying their work.

[0028] Furthermore, the linkage mechanism includes a first connecting rod 19, and second through holes 18 are correspondingly opened on both sides of the infusion support 1. The height of the second through holes 18 is relatively long, so as not to affect the movement of the first connecting rod 19. The first connecting rod 19 is inserted through the second through hole 18. The end of the first connecting rod 19 away from the second connecting block 17 is rotatably connected to a third connecting block 20. A second screw 21 is threadedly connected to the third connecting block 20. The two ends of the second screw 21 are rotatably connected to the infusion support 1 and the fixing box 12, respectively. Since the first connecting rod 19 is rotatably connected to the second connecting block 17, as the circular plate 14 gradually rises, the end of the first connecting rod 19 away from the second connecting block 17 gradually moves away from the infusion support 1. Since the third connecting block 20 is threadedly connected to the second screw 21, the first connecting rod 19 drives the third connecting block 20, which is rotatably connected to it, to gradually move away from the infusion support 1. The threaded connection between the two is more stable than the sliding connection between the two, and avoids the third connecting block 20 from frequently sliding left and right on the second screw 21.

[0029] Furthermore, a second connecting rod 22 is rotatably connected to the upper part of the second screw 21, and a fourth connecting block 23 is rotatably connected to the end of the second connecting rod 22 away from the second screw 21. A third screw 24 is threadedly connected to the fourth connecting block 23. The two ends of the third screw 24 are rotatably connected to the infusion bracket 1 and the fixing box 12, respectively. A support rod 25 is fixedly connected to one side of the fourth connecting block 23. A pressure sensor 26 is located at the end of the support rod 25 away from the fourth connecting block 23. The support rod 25 is slidably sleeved in the infusion bracket 1, and when the fourth connecting block 23 is closest to the infusion bracket 1, the support rod 25 can extend to the other side of the infusion bracket 1.

[0030] Specifically, when the fourth connecting block 23 moves to the position closest to the infusion support 1, the support rod 25 can pass through the infusion support 1 and make the pressure sensor 26 at its end face and contact the upper surface of the circular plate 14.

[0031] As the third connecting block 20 moves away, the end of the second connecting rod 22 connected to the third connecting block 20 moves away from the infusion bracket 1. The other end of the second connecting rod 22 is connected to the fourth connecting block 23, so the fourth connecting block 23 moves closer to the infusion bracket 1. Since the support rod 25 is fixedly connected to the fourth connecting block 23, the support rod 25 moves closer to the infusion bracket 1 as the fourth connecting block 23 moves closer to the infusion bracket 1. When the fourth connecting block 23 moves to the closest point to the infusion bracket 1, the pressure sensor 26 on the lower surface of the other end of the support rod 25 is pressed against the upper surface of the circular plate 14. That is, the pressure sensor 26 at the other end of the support rod 25 will come into contact with the upper surface of the circular plate 14 and be pushed upward by the circular plate 14, thereby applying pressure to the pressure sensor 26.

[0032] Furthermore, a button 27 and a second hook 28 are fixedly provided on the side of the infusion stand 1. The button 27 is used to activate the drive component 3, and the second hook 28 is used to hang the remaining medication of the patient. Before the infusion, the nurse hangs all the patient's medication on the infusion stand 1. Then, when the nurse changes the medication, there is no need to carry the medication from the nurse station. This is convenient for the nurse's work and avoids the medication being mixed up due to excessive medication at the nurse station.

[0033] Working principle: When in use, the IV drip is suspended on the first hook 15, and the other IV drips are suspended on the second hook 28. After the IV drip is suspended on the first hook 15, due to the presence of a certain amount of liquid in the IV drip, the spring 13 is pulled down by gravity. The spring 13 is deformed by the force and its length is extended, which has a reaction force on the fixing box 12 and the circular plate 14.

[0034] Press button 27 to control the drive unit 3 to open. The drive unit 3 drives the first screw 4 to rotate. Since the first connecting block 6 is threadedly connected to the first screw 4, the first connecting block 6 moves vertically upward or downward during the rotation of the first screw 4, thereby driving the support platform 7 to move vertically upward or downward. Once it moves to the height of the patient, the drive unit 3 can be closed, and then the patient can place their arm on it for infusion.

[0035] If the infusion is to be performed in cold weather or when the medication is irritating, first remove the heating device from the T-shaped slot 8 on the lower surface of the support platform 7, open the cover, and inject hot water of suitable temperature into the inner cavity of the semi-cylindrical container 10 from the container cover 11. Then close the cover and insert the heating device into the T-shaped slot 8 on the upper surface of the support platform 7. At this time, the heating device is located on the upper part of the patient's arm and heats the air inside the heating device.

[0036] As the infusion time increases, the amount of medicine in the IV bag gradually decreases, meaning the downward pull on spring 13 gradually decreases. Consequently, under the action of the reaction force, the length of spring 13 gradually shortens, causing the circular plate 14 and the first hook 15 to gradually rise. During the process of the circular plate 14 gradually rising, the end of the first connecting rod 19 away from the second connecting block 17 gradually moves away from the infusion support 1, thereby causing the third connecting block 20, which is rotatably connected to it, to gradually move away from the infusion support 1. Then, through the second connecting rod 22, the fourth connecting block 23 gradually moves closer to the infusion support 1, which in turn causes the support rod 25, which is fixedly connected to the fourth connecting block 23, to gradually move towards the infusion support 1. When the fourth connecting block 23 moves to the closest point to the infusion support 1, the pressure sensor 26 on the lower surface of the other end of the support rod 25 is pressed against the upper surface of the circular plate 14.

[0037] When the IV drip reaches its highest point, the pressure sensor 26 inside the linkage mechanism presses against the upper surface of the circular plate 14, exceeding the threshold. Then, the pressure sensor 26 transmits a signal to the main controller, which activates the alarm and displays the bed number on the screen. The nurse then goes to the ward according to the bed number to change the IV fluid for the patient.

[0038] When the nurse replaces the IV drip with a fully loaded one, the weight of the drip will stretch the spring 13 again, causing the circular plate 14 to move downwards. This movement is then reversed via the linkage mechanism, causing the pressure sensor 26 to disengage from the circular plate 14. The system then automatically resets and waits for the next alarm.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
