When in use, the Murphy's dropper is engaged between the two positioning plates 6, so that the Murphy's dropper can be positioned by the two positioning plates 6 to avoid the Murphy's dropper piece from being offset;
[0023] To further explain, Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, a controller 11 is preferably included, and the controller 11 is installed in the installation box 4, wherein a transmitter 7 for emitting light is installed on one positioning plate 6, and a receiver 10 for receiving light is installed on the other positioning plate 6, and the controller 11 is electrically connected to the buzzer 12 and the display screen 5 respectively; the controller 11 is used to receive and process the signals transmitted by the transmitter 7 and the receiver 10, and to control the start and stop of the buzzer 12; in this embodiment, the controller 11 can adopt a control system such as a microcontroller and a single-chip microcomputer, and the controller 11 is electrically connected to the buzzer 12, the display screen 5, the transmitter 7 and the receiver 10 respectively; the transmitter 7 and the receiver 10 are aligned with the axis of the Murphy's dropper; in this embodiment, the transmitter 7 and the receiver 10 respectively adopt an infrared transmitter and an infrared receiver, and the infrared receiver itself can only receive infrared light signals, and convert them into electrical signals and transmit them to the controller 11 for processing and analysis. When the liquid medicine passes through the infrared rays emitted by the transmitter 7, it will cause the scattering of the infrared rays, so that the light signal received by the receiver 10 will fluctuate in strength, and the infrared transmitter and the infrared receiver are both existing products; when in use, the infrared transmitter and the infrared receiver are used. The transmitter 7 and the receiver 10 are respectively located on both sides of the Murphy's dropper. The receiver 10 receives the infrared light signal from the transmitter 7. When liquid medicine drips from the Murphy's dropper, the liquid will pass through the space between the receiver 10 and the transmitter 7. The infrared light signal emitted by the transmitter 7 will be interfered by the liquid medicine. The intensity of the infrared light signal received by the receiver 10 from the transmitter 7 will change for a moment. The fluctuation data of the intensity of the infrared light signal from the receiver 10 will be transmitted to the controller 11. The receiver 10 will receive and record each fluctuation data and store the fluctuation data within the time period after a period of time. The number of fluctuation data is transmitted to the display screen 5, and the number is displayed on the display screen 5, so that the medical staff can clearly see the dripping speed of the medicine in the Murphy's dropper, which is convenient for adjusting the dripping speed of the medicine in real time; when the dripping speed of the medicine in the Murphy's dropper is faster than the maximum value or lower than the minimum value, the controller 11 will control the buzzer 12 to alarm, and when the medicine in the Murphy's dropper is no longer dripping, the controller 11 will also control the buzzer 12 to alarm, so that the patient himself, the accompanying personnel and the medical staff can find out in time that the liquid in the infusion bottle is empty, avoiding unnecessary harm to the patient's body;This scheme as a whole constitutes a dripping speed monitoring component for monitoring the dripping speed of the Chinese medicine liquid in Murphy's dropper. Of course, the dripping speed monitoring component can also use a photoresistor, a light-emitting element and a controller. The photoresistor and the light-emitting element are aligned parallel to each other and fixed on the positioning plate 6. The photoresistor and the light-emitting element are aligned with the axis of the Murphy's dropper respectively. The controller is electrically connected to the photoresistor and the light-emitting element and fixed in the installation box 4. The photoresistor is a semiconductor element based on the internal photoelectric effect. Its resistance value changes with the change of the incident light intensity. The light emitted by the light-emitting element is received by the photoresistor. When the liquid medicine drips, the light emitted by the light-emitting element will be scattered by the liquid medicine, so that the light signal received by the photoresistor is reduced for a moment. The controller receives, processes and records the fluctuating data. The number of fluctuating data in the time period will be transmitted to the display screen 5 within a period of time. When the dripping speed exceeds or falls below a certain threshold, and when the liquid medicine stops dripping, the controller will control the buzzer 12 to sound an alarm. ;
