Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infusion alarm. Background Art

[0002] An infusion set is a medical device used to deliver medication or liquids into a patient's body. It typically consists of an infusion tube, a dropper, an infusion needle, and other components. The infusion set controls the flow rate of medication or liquids through gravity or mechanical pumps, ensuring they are accurately delivered to the patient's body according to doctor's orders. Infusion sets are widely used in medical practice and are an important tool for treatment, fluid replacement, and drug infusion. As they are used, they are becoming increasingly intelligent. Alarms are paired with infusion sets for monitoring, enabling flow and liquid level detection during infusion. Automatic alarms are activated if an abnormality is detected, eliminating the need for medical staff to frequently patrol for fluid replacement, reducing the consumption of human resources.

[0003] Current infusion alarms usually use infrared liquid level sensors installed on the outside of the dropper to detect liquid levels and generate alarms. Such alarms are generally small and lightweight, but patients may easily misoperate them and pull the infusion tube, thereby causing infusion interruption. Current alarms do not have good protection functions and are single in functionality. They cannot monitor the number of drops and changes in the drip rate, and their use effect is poor.

During installation, the infrared liquid level sensor 403 is fitted with the top of the dropper 2. At this time, the torsion spring clip 402 is mounted on the outer wall of the dropper 2 to complete the fixation. During operation, the liquid level data is recorded by the infrared liquid level sensor 403. When the liquid level data is too high or too low, the controller 404 processes the data and starts the alarm light 405 to start the alarm, so that the staff can arrive and deal with it in time.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, the fixing mechanism 3 includes a fixing frame 5, a threaded column 6 and a load-bearing component 7. The threaded column 6 is threadedly connected to the fixing frame 5. A load-bearing component 7 is provided on one side of the fixing frame 5. The load-bearing component 7 includes a mounting frame 701 fixedly connected to the fixing frame 5. A rotating shaft 702 is rotatably connected to the mounting frame 701. An axial hole corresponding to the rotating shaft 702 is opened on the mounting frame 701, and the rotating shaft 702 passes through the center of the axial hole; so that the rotating shaft 702 can rotate at the center of the mounting frame 701, and then the connecting cable 703 can be driven to reel in the handle 704, and the connecting cable 703 is rotated to the Pull up the alarm component 4 to offset the gravity of the alarm component 4. At the same time, after the winding of the connecting cable 703 is fixed, the alarm component 4 no longer exerts pressure on the dropper 2, ensuring the connection stability between the dropper 2 and the infusion tube 1. The outer wall of the rotating shaft 702 is installed with a connecting cable 703, and the other end of the connecting cable 703 is installed with a hook 7031. A snap ring 7032 is installed on the mounting bracket 401. The hook 7031 and the snap ring 7032 are buckled together, so that the connecting cable 703 and the mounting bracket 401 can be detached by the hook 7031 and the snap ring 7032. The connection is convenient for the patient to carry the infusion device out of bed, which improves the portability of use. One end of the rotating shaft 702 is fixedly connected to the handle 704, the outer wall of the rotating shaft 702 is fixedly connected to the gear 705, the rear end face of the mounting frame 701 is fixedly connected to the support frame 706, and the support frame 706 is slidably connected to a tooth plate 707 that meshes with the gear 705. The top of the tooth plate 707 is fixedly connected to a mounting block 708, and a plurality of springs 709 are fixedly connected between the mounting block 708 and the support frame 706; buckle the hook 7031 and the snap ring 7032, and then pull the mounting block 708 upwards, The mounting block 708 moves upward and drives the tooth plate 707 to move, releasing the engagement between the tooth plate 707 and the gear 705. The handle 704 is then turned to reel in the connecting cable 703. After the connecting cable 703 is reeled in to a certain extent, it exerts an upward pulling force on the alarm component 4. At this time, the mounting block 708 is released. Due to the rebound force of the spring 709, the tooth plate 707 is reset and engages with the gear 705, completing the adjustment and fixation. At this time, the alarm component 4 no longer has a downward gravity on the dropper 2. The connecting cable 703 bears the gravity of the alarm component 4. The alarm component 4 is equipped with a lighting lamp 8.

[0026] The working principle of the present invention is as follows: first, the fixing mechanism 3 is installed on the placement rack of the medicine bottle, the fixing rack 5 is installed with the placement rack, and the threaded column 6 is rotated to clamp and fix it so that it is stably fixed, and then the alarm component 4 is installed on the outer wall of the dropper 2 so that the infrared liquid level sensor 403 is located at the top of the dropper 2, the torsion spring clamp 402 is opened, and then the dropper 2 is placed in the center of the torsion spring clamp 402 to complete the fixation, and then one end of the infusion tube 1 is inserted into the medicine bottle for infusion, and the hook 7031 is buckled with the snap ring 7032, and then the mounting block 708 is pulled upward, and the mounting block 708 moves upward while driving the tooth plate 707 to move, releasing the engagement between the tooth plate 707 and the gear 705, and then the handle 704 is turned to reel in the connecting cable 703, and the connecting cable After 703 is rolled up to a certain extent, it exerts an upward pulling force on the alarm component 4. At this time, the mounting block 708 is released. Due to the rebound force of the spring 709, the tooth plate 707 is reset and meshed with the gear 705, completing the adjustment and fixation. At this time, the alarm component 4 no longer has a downward gravity on the dropper 2. The connecting cable 703 bears the gravity of the alarm component 4. After waiting for the central liquid level of the dropper 2 to stabilize, the liquid level data is recorded through the infrared liquid level sensor 403. When the liquid level data is too high or too low, the controller 404 processes the data and starts the alarm light 405 to start the alarm. The staff can arrive and deal with it in time. The lighting lamp 8 can facilitate nurses to observe the fluid infusion situation during night patrols without turning on the ward headlights, ensuring the normal rest of the patients and having a better use effect.
