Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an infusion set and its control system. Background Technology

[0002] In the medical field, intravenous infusion therapy is a common and important treatment method used to replenish body fluids, nutrients, and medications. Traditional infusion sets mainly consist of infusion bottles / bags, infusion tubing, drip chambers, and needles. Their function is relatively simple, relying primarily on medical staff to manually adjust the drip rate and monitor the infusion status. This has several shortcomings: 1. Limitations of manual adjustment: Medical staff need to frequently check and manually adjust the drip rate to meet the patient's specific needs. This not only increases their workload but also, in emergencies, may lead to improper drip rates due to human error, affecting treatment effectiveness. 2. Lack of real-time monitoring: Traditional infusion sets cannot monitor the infusion status in real time, such as low fluid levels, abnormal drip rates, or changes in drug temperature. This can easily lead to infusion interruptions, air embolism, or patient discomfort, posing a potential threat to patient safety. 3. Lack of alarm mechanisms: The lack of an effective alarm system means that infusion abnormalities, such as excessively fast or slow drip rates or low fluid levels, are often not detected in time, delaying treatment and increasing treatment risks. Therefore, we propose an infusion set and its control system. Summary of the Invention

[0003] The main objective of this invention is to provide an infusion set that can effectively solve the problems in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An infusion set includes a housing body and an infusion tubing fixedly connected within the housing body. The two ends of the infusion tubing pass through the upper and lower ends of the housing body and extend to the outside of the housing body. A low-speed regulating device and a liquid level sensing device connected to the infusion tubing are provided inside the housing body. A heating device acting on the infusion tubing is provided inside the housing body. An alarm device connected to the liquid level sensing device, the drip rate regulating device, and the heating device is provided inside the housing body.

[0006] As a further improvement to the above solution, the housing body includes a rear housing and a front cover plate. The left and right sides of the rear housing are integrally formed with side connecting plates. The front cover plate is detachably installed at the front end of the rear housing through the side connecting plates on both sides. The front end of the front cover plate is provided with a display screen, indicator lights, an alarm and function selection buttons.

[0007] As a further improvement to the above solution, each of the two side connecting plates is provided with two sliding grooves at their opposite ends, and a connector is slidably connected to each other in the two sliding grooves. Each of the two side connecting plates is provided with two guide grooves on the side away from the opposite ends, and the two guide grooves correspond to the positions of the two sliding grooves respectively, and the guide grooves communicate with the interior of the corresponding sliding grooves.

[0008] As a further improvement to the above solution, the connector includes a slider that works with the slide groove. The slider is slidably connected inside the slide groove. Two springs are fixedly connected to one end of the slider. The ends of the springs away from the slider are fixedly connected to the inner wall of the slide groove. Two insert rods are fixedly installed on the ends of the slider away from the springs. The insert rods penetrate the inner wall of the slide groove and extend to the outside of the slide groove. A pull rod is provided on the slider and is slidably connected to the guide groove.

[0009] As a further improvement to the above solution, a liquid inlet is provided at the upper end of the rear housing, and a liquid outlet is provided at the lower end of the rear housing. Protective sleeves are embedded in both the liquid inlet and the liquid outlet.

[0010] As a further improvement to the above solution, the lower end of the infusion pipeline passes through the protective sleeve inside the inlet and the protective sleeve inside the outlet in sequence and extends to the bottom of the rear housing.

[0011] As a further improvement to the above solution, both the left and right ends of the rear housing are provided with connecting grooves for use with the side connecting plates, and the inner wall of the connecting groove is provided with insertion holes for use with the insertion rod.

[0012] As a further improvement to the above solution, the two side connecting plates are slidably connected in the connecting grooves on the left and right sides of the rear housing, and the plug is engaged in the corresponding plug hole to fix the front cover plate to the front end of the rear housing.

[0013] The present invention also discloses a control system for an infusion set, including the aforementioned infusion set, a sensing and detection unit, a data comparison unit, and a system alarm unit. The data comparison unit is connected to the sensing and detection unit and the system alarm unit. The data comparison unit is used to read the value output by the sensing and detection unit, compare it with a set value, and determine whether the current status information is correct. The system alarm unit is used to issue an alarm prompt to trigger a system alarm when the current status information is not correct.

[0014] As a further improvement to the above solution, the control system also includes a control unit for controlling the opening and closing of the liquid level sensing device, the drip rate regulating device, the heating device, and the alarm device based on the detection results of the data comparison unit.

A heating device acting on the infusion tubing 2 is provided inside the housing body 1. An alarm device connected to the liquid level sensing device, the drip rate regulating device, and the heating device is provided inside the housing body 1.

[0034] In a specific embodiment, the housing body 1 includes a rear housing 3 and a front cover plate 4. Side connecting plates 5 are integrally formed on both the left and right sides of the rear housing 3.

The connecting member 53 includes a slider 531 that cooperates with the sliding groove 51. The slider 531 is slidably connected within the sliding groove 51. Two springs 532 are fixedly connected to one end of the slider 531, with the springs 532 located away from the slider. One end of slider 531 is fixedly connected to the inner wall of slide 51. Two insert rods 533 are fixedly installed at the end of slider 531 away from spring 532. The insert rods 533 penetrate the inner wall of slide 51 and extend to the outside of slide 51. A pull rod 534 is provided on slider 531 and is slidably connected to guide groove 52. Both the left and right ends of the rear housing 3 are provided with connecting grooves 34 that cooperate with side connecting plates 5. The inner wall of the connecting grooves 34 is provided with insertion holes 35 that cooperate with insert rods 533. The two side connecting plates 5 are slidably connected in the connecting grooves 34 on the left and right sides of the rear housing 3, and the insert rods 533 are engaged in the corresponding insertion holes 35 to fix the front cover plate 4 to the front end of the rear housing 3. This realizes quick disassembly and assembly between the front cover plate and the rear housing, which facilitates the maintenance and cleaning of the device inside the housing body 1, reduces maintenance costs, and facilitates the installation of infusion tubing. The operation is convenient.

[0035] In a specific embodiment, the upper end of the rear housing 3 is provided with an inlet 31, and the lower end of the rear housing 3 is provided with an outlet 32.

[0038] It should be noted that this invention relates to an infusion set and its control system, the working principle of which is as follows:

[0039] (1) Preliminary preparations: Squeeze the pull rods 534 on both sides, and slide the slider 531 in the slide groove 51 by sliding the pull rods 534 in the guide groove 52. Use the spring 532 to compress and store the insertion rod 533 in the slide groove 51. Then separate the rear housing 3 and the front cover plate 4. Then connect one end of the infusion tubing 2 to the infusion bottle, and the other end passes through the protective sleeve 33 on the inlet 31 and the protective sleeve 33 on the outlet 32 ​​in sequence to connect to the needle converter. Then fix the front cover plate 4 to the front end of the rear housing 3.

[0040] (2) Liquid level sensing and drip rate adjustment: The liquid level sensing device continuously monitors the liquid level in the infusion bag. When the liquid level is detected to be lower than the preset value, the drip rate adjustment device automatically slows down or stops the drip rate to prevent air from entering the blood vessels. At the same time, the heating device keeps the medicine solution within a suitable temperature range to reduce patient discomfort.

[0041] (3) Intelligent alarm mechanism: Once the system detects that the liquid level is too low, the drip rate is abnormal or the heating is faulty, the system alarm unit will be activated immediately and emit sound or light signals through the alarm to remind medical staff to take appropriate measures.

[0042] (4) Coordinated operation of the control system: The control unit intelligently analyzes and adjusts the working status of the liquid level sensing device, drip rate regulating device and heating device based on the real-time data of the sensing and detection unit to ensure the safety and effectiveness of the infusion process.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
