Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical assistance technology, and particularly to a self-heating infusion system. Background Art
[0002] In clinical treatment, intravenous infusion is one of the common treatment methods. Especially for critically ill, postoperative or weak patients, continuous and large amounts of infusion are often required to maintain the balance of water and electrolytes or deliver drugs. However, during the infusion process, especially when the environmental temperature is low or the infusion speed is fast, the direct entry of low-temperature liquid into the patient's blood vessels may cause heat loss, leading to adverse reactions such as shivering, vasospasm, and even hypothermia. This not only increases the discomfort of the patient, but also may affect the treatment effect and even bring additional medical risks.
[0003] Currently, in clinical practice, natural rewarming or simple heating methods (such as using hot water bags, warm babies, etc.) are usually used to heat the infusion liquid. However, the temperature control of these methods is not accurate, which may cause the liquid to overheat or be underheated, affecting safety or comfort. In addition, this traditional heating method requires manual intervention and cannot be seamlessly connected with the infusion process, increasing the workload of medical staff.
[0004] Therefore, there is an urgent need for a new type of infusion heating device to provide an effective solution to the defects of the existing technology. Summary of the Invention
[0005] The purpose of the present invention is to provide a self-heating infusion system to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the present invention provides the following technical solutions:
[0007] A self-heating infusion system includes a controller and an infusion tube heating sleeve: The infusion tube heating sleeve includes a vertical hinge column, and a pair of half sleeves are rotatably installed on the vertical hinge column. The half sleeve is a semi-cylindrical structure, and a semi-tube groove with the same semi-cylindrical structure is provided on the inner side. When the two half sleeves are combined, they form a cylindrical structure, and a cylindrical tube groove is formed at the central position. Electric heating sheets are provided on the surfaces of the two semi-tube grooves. A temperature sensor is provided at the bottom of one side of the semi-tube groove. The temperature sensor and the electric heating sheet are electrically connected to the controller through wires. A display screen, a power switch, a temperature setting button, and a time setting button are provided on the front of the controller.
[0008] Further, a normal working state indicator light and a temperature deviation indicator light are provided on the top of the controller. The normal working state indicator light emits green light, and the temperature deviation indicator light emits yellow light.
[0009] Further, a liquid level sensor is provided at the bottom of the half pipe groove on the side where the temperature sensor is not installed. The liquid level sensor is also electrically connected to the controller through a wire. A liquid break warning light is provided at the top of the controller, and the liquid break warning light emits red light. A liquid break buzzer is provided on the side of the controller, and the liquid break buzzer emits an alarm sound. A reset button is provided at the bottom of the front of the controller, and the reset button is used to turn off the liquid break buzzer and the liquid break warning light.
[0010] Further, a wireless signal transmission module is also provided in the controller. When the liquid level sensor detects that the liquid level in the infusion tube drops to this position or the temperature sensor detects that the infusion temperature deviates from the set range, the wireless signal transmission module automatically sends a signal to the nurse station.
[0011] Further, convex rubber edges are equidistantly distributed on the surface of the half pipe groove from top to bottom. After the two half sleeves on both sides are combined, the rubber edges are closely attached to the outer surface of the infusion tube.
[0012] Further, strip-shaped grooves are provided on the end faces of both half sleeves on the side away from the vertical hinge column. Permanent magnets are installed in the strip-shaped grooves. After the two half sleeves on both sides are combined, the permanent magnets on both sides adsorb each other. Finger plates protruding outward are provided on the outer surfaces of both half sleeves on the side away from the vertical hinge column.
[0013] Further, a heat insulation layer is provided inside the half sleeve.
[0014] Further, the controller is detachably installed on the vertical column of the infusion rack. A sleeve is sleeved on the vertical column of the infusion rack. A locking screw is threadedly connected to the sleeve. A handle is provided at one end of the locking screw extending out of the sleeve. A socket is provided on the circumferential outer wall of the sleeve. A plug is provided at the rear of the controller. The plug is in plug-in fit with the socket. The socket is an arc-shaped tile-like structure closely attached to the surface of the column, and the plug is also an arc-shaped tile-like structure.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] 1. Through the closed-loop control of the electric heating sheet, temperature sensor, and controller, the present invention ensures a constant infusion temperature, preventing problems such as patient shivering and hypothermia; and the liquid level sensor cooperates with the liquid break alarm to automatically remind, eliminating the need for manual inspection of the infusion progress. The present invention effectively solves the problems of inaccurate temperature and dependence on manual labor in traditional infusion heating methods, significantly improving the safety of infusion and the efficiency of medical care.
[0017] 2. Through wireless alarm, nurses can master the abnormal infusion situation without frequently traveling back and forth to the hospital beds, greatly reducing the work intensity. At the same time, it reduces the risks of blood backflow or temperature out of control caused by the failure to handle in time after the infusion is completed, improving medical safety and management efficiency. The present invention realizes the remote intelligent monitoring of the infusion state, overcomes the lag of traditional manual inspections, and is especially applicable to the unattended scenarios at night or in busy wards.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0028] Example 1: A self-heating infusion system, including a controller 2 and an infusion tube heating sleeve 18: The infusion tube heating sleeve 18 includes a vertical hinge post 19, and a pair of half sleeves 20 are rotatably installed on the vertical hinge post 19. The half sleeves 20 are of a semi-cylindrical structure, and a semi-tube groove 26 of the same semi-cylindrical structure is provided on the inner side. After the two side half sleeves 20 are combined, they form a cylindrical structure, and a cylindrical tube groove is formed at the central position. Electric heating sheets 22 are provided on the surfaces of the two side semi-tube grooves 26. A temperature sensor 27 is provided at the bottom of one side semi-tube groove 26. The temperature sensor 27 and the electric heating sheets 22 are electrically connected to the controller 2 through wires 17. A display screen 3, a power switch 4, a temperature setting button 5, and a time setting button 6 are provided on the front of the controller 2.
[0029] A normal working state indicator light 9 and a temperature deviation indicator light 10 are provided on the top of the controller 2. The normal working state indicator light 9 emits green light, and the temperature deviation indicator light 10 emits yellow light.
[0030] A liquid level sensor is provided at the bottom of the semi-tube groove 26 of the half sleeve 20 on the side where the temperature sensor 27 is not installed. The liquid level sensor is also electrically connected to the controller 2 through wires 17. A liquid break warning light 11 is further provided on the top of the controller 2. The liquid break warning light 11 emits red light. A liquid break buzzer 8 is provided on the side of the controller 2. The liquid break buzzer 8 emits an alarm sound. A reset button 7 is provided at the bottom of the front of the controller 2. The reset button 7 is used to turn off the liquid break buzzer 8 and the liquid break warning light 11.
[0031] Convex rubber ridges 23 are equidistantly distributed on the surface of the semi-tube groove 26 from top to bottom. After the two side half sleeves 20 are combined, the rubber ridges 23 closely adhere to the outer surface of the infusion tube.
[0032] Bar-shaped grooves 24 are provided on the end faces of the two side half sleeves 20 away from the vertical hinge post 19. Permanent magnets 25 are installed in the bar-shaped grooves 24. After the two side half sleeves 20 are combined, the two side permanent magnets 25 adsorb each other. Finger plates 21 protruding outward are provided on the outer surfaces of the two side half sleeves 20 away from the vertical hinge post 19.
[0033] A heat insulation layer is provided inside the half sleeve 20.
[0034] Working principle of this embodiment:
[0035] When this embodiment is in use, as Figures 6-7 shown, the operator opens the two side half sleeves 20 through the finger plates 21 and places the infusion tube into the semi-tube groove 26. The half sleeves 20 rotate and close through the vertical hinge post 19 and are adsorbed and fixed by the permanent magnets 25 to form a complete cylindrical tube groove to wrap the infusion tube. The rubber ridges 23 closely fit the outer wall of the infusion tube to prevent sliding. As Figures 2-4As shown, the target temperature and working time are set through the time setting button 6 and temperature setting button 5 of the controller 2. The electric heating sheet 22 starts to work to heat the liquid in the infusion tube. The temperature sensor 27 monitors the liquid temperature in real time and feeds the data back to the controller 2. The normal working status indicator light 9 lights up green, indicating that the system is operating normally. If the temperature is abnormal, the temperature deviation indicator light 10 lights up yellow. The liquid level sensor is located at the bottom of the half-tube slot 26 on the side where the temperature sensor is not installed to detect the infusion status. If a break in the flow or the end of the infusion is detected, the controller 2 triggers the liquid break warning light 11 and the liquid break buzzer 8 to alarm. Pressing the reset button 7 can turn off the alarm.
[0036] As Figures 7-8 shown, a heat insulation layer is provided inside the half set 20 to reduce heat dissipation and improve the heating efficiency.
[0037] In this embodiment, through the closed-loop control of the electric heating sheet 22, temperature sensor 27, and controller 2, it is ensured that the infusion temperature is constant, preventing problems such as patient shivering and hypothermia; and the liquid level sensor cooperates with the liquid break alarm to provide automatic reminders without the need for manual inspection of the infusion progress. This embodiment effectively solves the problems of inaccurate temperature and dependence on manual labor in traditional infusion heating methods, significantly improving the safety of infusion and the efficiency of medical care.
[0038] Embodiment 2: A self-heating infusion system, which is different from Embodiment 1 in that a wireless signal transmission module is also provided in the controller 2. When the liquid level sensor detects that the liquid level in the infusion tube drops to this position or the temperature sensor 27 detects that the infusion temperature deviates from the set range, the wireless signal transmission module automatically sends a signal to the nurse station.
[0039] The working principle of this embodiment:
[0040] The built-in wireless signal transmission module of the controller 2 uses low-power Bluetooth (BLE) or Wi-Fi technology to wirelessly connect to the central monitoring system of the nurse station. When the liquid level sensor detects that the liquid level in the infusion tube drops to the set threshold (such as approaching the end of infusion) or the temperature sensor 27 monitors that the liquid temperature exceeds the preset range (such as a deviation of ±2°C), the controller 2 immediately sends a real-time alarm signal to the nurse station through the wireless signal transmission module. The main control terminal of the nurse station can display the specific bed number, alarm type (liquid break or temperature abnormality), and current value, and supports sound and light reminders to ensure that medical staff respond in a timely manner. This module uses adaptive signal strength adjustment technology to avoid communication interruption due to distance or interference, and at the same time has low-power characteristics to ensure long-term stable operation.
[0041] This embodiment realizes the remote intelligent monitoring of the infusion state, overcomes the lag of traditional manual inspections, and is especially suitable for unattended scenarios at night or in busy wards. Through wireless alarms, nurses can grasp the abnormal infusion conditions without frequently traveling back and forth to the hospital beds, greatly reducing the work intensity. At the same time, it reduces the risks of blood backflow or temperature out of control caused by the failure to handle the infusion completion in a timely manner, improving medical safety and management efficiency.
[0042] Embodiment 3: A self-heating infusion system, which is different from Embodiment 1 in that the controller 2 is detachably installed on the column of the infusion stand 1. A sleeve 14 is sleeved on the column of the infusion stand 1. A locking screw 15 is threadedly connected to the sleeve 14. One end of the locking screw 15 extending out of the sleeve 14 is provided with a handle 16. A socket 13 is provided on the circumferential outer wall of the sleeve 14. A plug 12 is provided on the rear side of the controller 2. The plug 12 is in plug-in fit with the socket 13. The socket 13 is an arc-shaped tile-like structure closely attached to the surface of the column, and the plug 12 is also an arc-shaped tile-like structure.
[0043] The working principle of this embodiment:
[0044] As Figure 1 、 Figure 3 、 Figure 5 and Figure 6 shown, the controller 2 realizes the quick disassembly and assembly with the infusion stand 1 through the plug-in structure. Specifically, the sleeve 14 is sleeved on the column of the infusion stand, and the position is fixed by the locking screw 15 with the handle 16. The arc-shaped tile-like socket 13 provided on the outer wall of the sleeve 14 forms a tight plug-in fit with the plug 12 of the same structure on the rear side of the controller 2. The profiling design not only ensures a firm connection but also facilitates the disassembly and assembly operations and does not occupy space.
