[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a drip chamber detection device, see embodiments thereof. Figure 1 and Figure 2 The device includes a fixing component for detachable connection with the dropper to be tested. A sensor is provided on the side of the fixing component connected to the dropper to sense the liquid information in the dropper. The sensor is connected to a signal transmission line to transmit the liquid information in the dropper.
[0032] In this embodiment, the drip chamber detection device is mainly connected to the drip chamber to acquire the parameters of the liquid in the drip chamber. In specific implementation, it is preferable to detachably connect to the drip chamber to be tested through a fixing member, which can be recycled. A sensor is set on the side of the fixing member connected to the drip chamber to sense the liquid information in the drip chamber and output parameter information through a signal transmission line. After acquiring the parameter information, such as the drip rate or the liquid volume in the drip chamber, intelligent control can be achieved to avoid the drip rate being too fast or too slow. It can also monitor the liquid volume in the drip chamber to add medicine in time or complete the infusion.
[0033] See Figure 1 and Figure 3 In some possible embodiments of this application, the drip detection device includes a first clamping member and a second clamping member, which are rotatably connected.
[0034] In this embodiment, the fixing member preferably includes two clamping members. The first clamping member and the second clamping member are rotated together to fix the member to the dripping container. When fixation is required, the first clamping member and the second clamping member are separated, and the first clamping member and the second clamping member rotate relative to each other to connect with the dripping container. After the first clamping member and the second clamping member are connected to the dripping container, a spring is provided at the connection between the first clamping member and the second clamping member. The elastic restoring force of the spring will drive the first clamping member and the second clamping member to return to their original positions, thereby clamping the dripping container and thus fixing the member to the dripping container.
[0035] In some possible embodiments of this application, the dripping chamber detection device includes a transmitter / receiver on the first clamping member and a receiver / transmitter at a corresponding position on the second clamping member. The dripping rate of the liquid in the dripping chamber is obtained by the data changes between the receiver and the transmitter.
[0036] In this embodiment, the dripping rate of the dripping bucket can be detected. A transmitter is provided on the first clamping member, and a receiver is provided on the second clamping member. In specific implementation, since the transmitter is sending signals in real time and the receiver is receiving signals, when the liquid drips, it will interfere with the signal of the transmitter, which may interrupt the signal or cause fluctuations, making the data received by the receiver different from the normal data. Therefore, the dripping rate of the liquid can be obtained based on the interval of the data difference, that is, the time interval between two abnormal occurrences.
[0037] See Figure 4 and Figure 5 In some possible embodiments of this application, the drip detection device includes a transmitter and a receiver on the first clamping member and a reflector on the second clamping member, through which the signal emitted by the transmitter is reflected.
[0038] In another embodiment of this application, both the transmitter and the receiver are mounted on the first clamp. In order for the receiver to receive data, a reflector is provided on the second clamp. The reflector reflects the signal emitted by the transmitter. By mounting the transmitter and receiver on the same clamp, it is easier to lay out the cables.
[0039] In some possible embodiments of this application, the drip detection device includes a transmitter used to emit an infrared signal.
[0040] In this embodiment of the application, the signal emitted by the transmitter is preferably an infrared signal, which has the following advantages:
[0041] 1. Non-contact detection: Infrared sensors do not need to contact the object being detected, thus avoiding problems such as mechanical wear and contamination, and will not cause damage to the object being detected.
[0042] 2. Fast response speed: Infrared sensors have a very fast response speed and can detect the state of objects in real time, with high real-time performance.
[0043] 3. Wide applicability: Infrared sensors can detect objects of different materials, shapes, and colors, making them widely applicable.
[0044] 4. High reliability: Infrared sensors are characterized by high precision, high sensitivity, and high stability, and can work for a long time in harsh environments.
[0045] In some possible embodiments of this application, the reflector in the drip detection device is preferably a reflective sheet.
[0046] In some possible embodiments of this application, the drip chamber detection device includes conductive cotton on the first clamping member and / or the second clamping member, and a capacitance detection electrode is provided on the side of the conductive cotton that contacts the drip chamber.
[0047] In this embodiment, the dripping chamber detection device can detect not only the dripping rate of the medicine in the dripping chamber, but also the remaining liquid level in the dripping chamber. Specifically, conductive cotton is provided on the first clamping member or the second clamping member, or conductive cotton is provided on both the first clamping member and the second clamping member. A capacitance detection electrode is provided on the side of the conductive cotton that contacts the dripping chamber. When the liquid level in the dripping chamber changes, the capacitance change can be detected by the capacitance detection electrode to know the change in the liquid level in the dripping chamber, thereby transmitting specific liquid level information and facilitating the determination of whether the medicine is sufficient.
[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
