[0002] Current infusion set technology is widely used in the medical field to deliver medications intravenously. These sets typically consist of an IV bag, tubing, and a needle, and are sterile-processed to ensure safety. During the infusion process, monitoring the status of the fluid is crucial to ensure the correct and safe delivery of the medication.

[0003] The existing Chinese patent with publication number CN217430591U discloses an auxiliary alarm device based on an infusion pump. The technical solution includes an infusion pump main body and an infusion auxiliary alarm component arranged thereon. The core innovation lies in using a temperature sensor to monitor the temperature changes of the infusion pump main body. Since the drug solution usually needs to be stored at low temperature, there is an obvious temperature difference between the infusion pump main body containing the drug solution and the infusion pump main body not containing the drug solution. By monitoring these temperature differences, the device can realize the alarm function of the infusion status and effectively avoid no alarm or false alarm. Although this technical solution provides a new method for monitoring the infusion status, there may still be some limitations. For example, the temperature sensor may be sensitive to changes in ambient temperature, which may lead to false alarms when the ambient temperature fluctuates greatly.

[0004] In view of the above-mentioned related technologies, an alarm device for an infusion set is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0027] Combine Figure 1-Figure 4, an alarm device for an infusion set comprises a main shell 1, a shell cover 2 is provided on the main shell 1, one end of the shell cover 2 is rotatably connected to the main shell 1, and the other end is connected to the main shell 1 by a snap buckle, and an observation slot 20 is provided on the shell cover 2, which is convenient for medical staff to intuitively observe the internal situation of the drip bucket and timely understand the infusion status; the main shell 1 and the shell cover 2 are sleeved on the drip bucket 3 of the infusion set and completely wrap it, and the coordinated design of the main shell 1 and the shell cover 2 enables the entire device to tightly wrap the drip bucket 3 of the infusion set, providing a stable and sealed monitoring environment; a charging port 11 is provided on the main shell 1, and a battery module 12 is installed on the main shell 1, which is convenient for charging the internal battery module 12 to ensure the continuous operation of the device; a buzzer 13 and an alarm light 14 are electrically connected to the battery module 12, and the alarm light 14 has two groups of different colors, which emit corresponding color warnings according to different warning levels, and remind medical staff to pay attention to changes in the infusion status in an intuitive way; a first-level warning unit 4 and a second-level warning unit 5 are provided on the main shell 1;

[0028] The secondary warning unit 5 includes a point sensor 51. The two point sensors 51 are respectively installed at the beginning and end of the contact between the main shell 1 and the drip bucket 3 infusion tube. The point sensor 51 is a capacitive proximity sensor. It adopts capacitive proximity sensor technology and can accurately detect the presence or absence of liquid in the drip bucket 3 and the change of the liquid flow state; the point sensor 51 is electrically connected to the electric telescopic rod 52 through the control module 6. The output end of the electric telescopic rod 52 is fixedly connected to the elastic pressure block 53. A buffer spring 54 is provided between the elastic pressure block 53 and the electric telescopic rod 52. When the liquid flow is abnormal, such as when the infusion stops or the flow is slow, it can respond quickly and trigger an early warning through the telescopic action.

[0029] The main shell 1 is provided with a crescent groove 10, a drip groove 30, a mounting groove 510 and a brake groove 520. The control module 6 is installed in the crescent groove 10, which serves as the core of the entire alarm system and is responsible for processing the signals from each sensor and triggering the corresponding alarm mechanism; a point sensor 51 is fixedly installed in the mounting groove 510, and an electric telescopic rod 52 is fixedly installed in the brake groove 520, further enhancing the functionality and stability of the device.

[0030] The control module 6 is electrically connected to the battery module 12 , the buzzer 13 , the alarm light 14 , the first-level warning unit 4 and the second-level warning unit 5 , respectively, thereby realizing dual monitoring of the infusion status.

[0031] The first-level warning unit 4 includes a pressure sensor 41 and a weighing sensor 42. The pressure sensor 41 and the weighing sensor 42 are symmetrically installed on both sides of the bottom end of the drip bucket 30. The pressure sensor 41 and the weighing sensor 42 are both in contact with the outer wall of the bottom end of the drip bucket 3, and can monitor the pressure and weight changes in the drip bucket in real time, providing more accurate feedback for the infusion status.

[0032] Working principle: The infusion status is monitored in real time through the first-level warning unit 4 and the second-level warning unit 5 to ensure the safety of infusion. The first-level warning unit 4 includes a pressure sensor 41 and a weighing sensor 42, which are symmetrically installed on both sides of the bottom end of the drip bucket 30 and abut against the outer wall of the bottom end of the drip bucket 3. The infusion status is detected by monitoring the pressure and weight changes of the drip bucket 3; the second-level warning unit 5 includes a point sensor 51, which is a capacitive proximity sensor installed at the beginning and end of the contact between the main shell 1 and the drip bucket 3 infusion tube. When there is no liquid flowing through the upper infusion tube, that is, the infusion may be interrupted, the point sensor 51 can immediately detect the change in capacitance value. This change is captured by the sensor and quickly fed back to the control module 6. The control module 6 then starts the preliminary warning program and issues a warning through the alarm light 14 to provide a warning. This alerts medical staff to check the infusion status, thus avoiding potential medical delays. If the flow interruption occurs in the lower infusion tube, near the drip chamber 3, the point sensor 51 can also detect the change in capacitance. In this case, the control module 6 not only sounds an alarm but also triggers the electric telescopic rod 52. The output end of the electric telescopic rod 52 is fixedly connected to an elastic pressure block 53, and a buffer spring 54 is sleeved between the elastic pressure block 53 and the electric telescopic rod 52. This structural design enables the electric telescopic rod 52 to promptly respond to the control module's instructions, pushing the elastic pressure block 53 through the telescopic action, thereby achieving the timely termination of the infusion procedure. The control module 6 is installed in the crescent groove 10 and is responsible for receiving signals from the first-level warning unit 4 and the second-level warning unit 5, and controlling the buzzer 13 and the alarm light 14 to provide audible and visual alarms. When an abnormal situation occurs, the buzzer 13 sounds an audible alarm, and the alarm light 14 provides a visual warning by lighting different colors. In addition, the housing 2 is provided with an observation slot 20 to facilitate medical staff to observe the infusion status in the drip chamber 3. The charging port 11 on the main housing 1 is used to charge the battery module 12 to ensure the continuous operation of the alarm device. The entire alarm device is connected to the main housing 1 through a rotating and snap-on connection between the shell cover 2 and the main housing 1, tightly wrapping the drip chamber 3 to achieve all-round monitoring and protection.
