[0033] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.
[0034] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0035] This invention provides an infusion drip rate detection alarm, which is used to detect the number of droplets within a set time during infusion, thereby realizing the detection of infusion drip rate.
[0036] like Figures 1 to 3 As shown, the infusion drip rate detection alarm includes a housing 1, a cover plate 2, and a power supply unit 101, a drip detection sensor 102, a main control unit 100, an alarm unit, and a near-field communication unit 103, all housed within the housing 1. A receiving groove 3, penetrating both ends of the housing 1, is provided on the first side of the housing 1, with the drip chamber 5 of the infusion tube located within the receiving groove 3. The cover plate 2 is detachably connected to the first side of the housing 1 via a snap-fit and slot-locking mechanism, with the drip chamber 5 of the infusion tube abutting between the cover plate 2 and the receiving groove 3. When installing the infusion drip rate detection alarm, first separate the cover plate 2 from the housing 1. After the drip chamber 5 of the infusion tube is placed in the receiving groove 3, reconnect the cover plate 2 to the housing 1. The cover plate 2 and the receiving groove 3 secure the drip chamber 5 of the infusion tube, thus stably attaching the infusion drip rate detection alarm to the drip chamber 5 of the infusion tube. This design facilitates easy installation and disassembly and convenient use. An observation window 4 is provided on the cover plate 2 for manual observation of the infusion drip rate within the drip chamber 5.
[0037] like Figures 2 to 4As shown, the drip detection sensor 102 is disposed on both sides of the receiving tank 3. The power supply unit 101, alarm unit, drip detection sensor 102, and near-field communication unit 103 are all connected to the main control unit 100. The main control unit 100 uses an existing circuit structure / integrated chip, and this application does not modify any circuit structure / chip of the main control unit 100. The power supply unit 101 supplies power to the entire device. The drip detection sensor 102 is used to detect when no liquid passes through within the interval of two drops or the minimum threshold interval, and the main control unit collects the signal from the drip detection sensor 102. The near-field communication unit 103 is used to communicate with a mobile phone or control device, allowing adjustment of the parameters of the main control unit 100 via the mobile phone or control device. These parameters include the drip rate threshold and alarm time. When the drip rate exceeds or falls below the threshold, the main control unit 100 issues an alarm signal through the alarm unit, making it convenient for medical personnel to be aware of the situation. It quantifies the drip rate and provides real-time alerts to medical staff to ensure that the drip rate does not exceed or fall below the threshold, thereby improving the accuracy of drip rate control by medical staff; it also avoids the safety hazards and space-consuming nature of relying solely on manual monitoring.
[0038] like Figure 2 As shown, the receiving tank 3 includes a first receiving tank 31 and a second receiving tank 32 that are interconnected. The first receiving tank 31 is connected to the lower end face of the housing 1, and the second receiving tank 32 is connected to the upper end face of the housing 1. The upper part of the drip chamber 5 of the infusion tube is located in the first receiving tank 31, and the conduit 6 of the infusion tube is located in the second receiving tank 32. Specifically, the bottom of the first receiving tank 31 is arc-shaped, and the shape of the first receiving tank 31 matches the shape of the drip chamber 5. The width of the first receiving tank 31 is slightly larger than the outer diameter of the drip chamber 5 to avoid inaccurate drip rate detection due to excessive gap between the drip chamber 5 and the first receiving tank 31. The width of the second receiving tank 32 is smaller than the outer diameter of the drip chamber 5 of the infusion tube. The upper end face of the drip chamber 5 abuts against the connection between the first receiving tank 31 and the second receiving tank 32. After installation, the infusion drip rate detection alarm is hung on the drip chamber 5 by its own weight, eliminating concerns about the infusion drip rate detection alarm falling off and improving the stability of the infusion drip rate detection alarm installation.
[0039] like Figure 3 As shown, the alarm unit includes a buzzer 104 and an indicator light 105. Both the buzzer 104 and the indicator light 105 are connected to the main control unit 100, and audible and visual alarms are provided through the buzzer 104 and the indicator light 105. Preferably, a through hole and a sound amplification hole are provided on the second side of the housing 1. The first side and the second side of the housing 1 are a pair of opposing surfaces. The indicator light 105 is disposed in the through hole, and the buzzer 104 is installed at the sound amplification hole.
[0040] like Figure 3As shown, the housing 1 is provided with an interactive button 11, which is connected to the main control unit 100 and is used for the interaction of the entire infusion drip rate detection alarm, including start / stop, mute, and unmute, which are achieved by the length of time the button is pressed.
[0041] In a preferred embodiment, the drip detection sensor 102 includes an infrared emitter and an infrared receiver arranged opposite each other. The infrared emitter and receiver are respectively connected to the two side walls of the receiving tank 3. The infrared light emitted by the infrared emitter passes through the dripping container 5 and illuminates the infrared receiver. When the liquid passes through, the liquid undergoes a series of optical phenomena, including but not limited to reflection, refraction, and scattering. The main control unit collects the intensity of the infrared light received by the infrared sensor. When the intensity of the infrared light differs from the normal value, it counts once. An infrared filter 7 is provided on the observation window 4 of the cover plate 2, which will not obstruct the user's view and can also prevent external infrared light from entering the receiving tank 3 and affecting the normal operation of the infrared receiver.
[0042] like Figure 3 As shown, the power supply unit 101 includes multiple stacked button batteries, reducing the weight and size of the device and lowering its cost, allowing it to be used as a disposable product. An insulating sheet is provided between any two adjacent button batteries. After removing the insulating sheet through an opening on the housing 1, the batteries become electrically connected, supplying power to start the device.
[0043] This invention addresses the practical use cases in hospitals, especially during surgery, by replacing manual monitoring of the infusion drip rate with an infusion drip rate detection and alarm device, thus achieving fully automatic and highly reliable drip rate monitoring and alarm.
