[0046] Example four

[0047] As shown in Figure 7 , the infusion drip speed adjusting device further comprises: a key area 20 located on the fixed frame 1, for issuing an instruction to the microcontroller 7 to set the time and flow rate.

At the same time, the microcontroller 7 is installed in the fixed frame 1, and is connected with the key area 20 and the display area 21 through wires.

[0050] As shown in Figure 8 The infusion drip rate adjusting device further comprises a conversion module 22 located on the microcontroller 7, which is used to convert the electrical signals transmitted by the flow sensor 12 and the electrical signals transmitted by the key area 20 into digital signals, so that the display area 21 displays.

[0051] It should be noted that the conversion module 22 receives signals from various input sources, including time, flow rate and other parameters set by medical staff through the key area 20, and real-time data fed back by various sensors (such as liquid level sensor, physiological parameter monitor, etc.).

[0052] As for the setting of the above-mentioned time, flow rate parameters, the collection and analysis of sensor data, and the display of data, the related programming is a conventional technical means in the field, and the operator can realize it only by setting the keys or buttons, which will not be described here.

[0053] The technical scheme provided by the utility model in the implementation:

[0054] The medical staff takes out the infusion tube 2, inserts one end of the infusion tube 2 into one of the circular grooves 19 formed at both ends of the fixed frame 1, then passes the infusion tube 2 through the roller clamp 3 located on the fixed frame 1, ensures that the infusion tube 2 is placed at a position where the roller clamp 3 can be normally adjusted, and finally makes the infusion tube 2 pass out from the circular groove 19 at the other end of the fixed frame 1, and then passes through the flow sensor 12 installed on one side of the fixed frame 1. At this time, the needle is installed at one end of the infusion tube 2, the other end of the infusion tube 2 is connected with the infusion bottle, and thus the installation preparation work of the infusion tube 2 on the device is completed.

[0055] According to the kind of liquid material to be injected, the patient's physical condition, and the treatment plan, etc., the required infusion speed at different time periods can be determined directly by operating the button area 20 on the fixed frame 1, and setting the corresponding infusion speed value according to the predetermined different time periods, and setting the infusion time period corresponding to each speed. After receiving the setting instruction, the button area 20 will transmit the relevant electrical signal to the central control module 8 in the microcontroller 7, and the central control module 8 will then send the signal to the speed setting module 9 and the time monitoring module 10, respectively. The central control module 8 will start the drive 6 installed on the side wall of the adjustment plate 4 in a timely manner according to the time parameters set in the button area 20.

[0056] After the drive 6 is started, it will drive the threaded rod 17 connected thereto to rotate. Since the threaded rod 17 is threadedly connected with the small slider 15 in the second sliding groove 14, and the threaded rod 17 is rotatably connected with the fixed block 16 at one end, when the threaded rod 17 rotates, the small slider 15 will slide in the second sliding groove 14. Since the small slider 15 is connected with the side wall of the sliding plate 5, and the first sliding groove 13 and the second sliding groove 14 are connected with each other, the sliding of the small slider 15 in the second sliding groove 14 will drive the sliding plate 5 to slide synchronously in the first sliding groove 13 on the side of the adjustment plate 4 close to the roller clamp 3. When the sliding plate 5 slides in the first sliding groove 13, the texture structure 18 provided on the side close to the roller clamp 3 will interact with the roller clamp 3. Through this meshing connection, the roller clamp 3 is driven to adjust the flow size of the liquid material in the infusion tube 2. After the liquid material in the infusion tube 2 is adjusted by the roller clamp 3, it will continue to flow through the flow sensor 12. The flow sensor 12 can monitor the flow of the adjusted infusion tube 2 in real time, and transmit the detected flow data to the microcontroller 7 through electrical signals. The conversion module 22 in the microcontroller 7 will convert the electrical signal transmitted by the flow sensor 12 into a digital signal, and then display it on the display area 21 on the fixed frame 1, so that medical personnel can intuitively understand the current flow rate of the infusion tube 2.

[0057] During the infusion process, the time monitoring module 10 in the microcontroller 7 continuously records the length of time after the infusion speed is adjusted, when the time monitoring module 10 records the same time period as the time period set by the speed setting module 9, the time monitoring module 10 sends a signal to the feedback adjustment module 11, after receiving the signal of the time monitoring module 10, the feedback adjustment module 11 transmits to the central control module 8 according to the speed set by the speed setting module 9 in the next time period, the central control module 8 controls the operation of the driving part 6 again according to the instruction transmitted by the feedback adjustment module 11, so as to adjust the flow of the liquid material in the infusion tube 2 according to the steps of the above infusion speed adjustment stage, and realize the automatic and accurate adjustment of the infusion speed according to the different time periods. Through the above complete working process, the functions of the infusion drop speed adjusting device can be fully utilized, efficient, accurate and automatic infusion drop speed adjustment is realized, and the smooth progress of infusion treatment is ensured.
