Embodiment 1
[0033] Embodiment 1: Example of product preparation of the present invention
[0034] The main structure of the product is as image 3 As shown, the specific parameters of the main components are:
[0035] 1. Single-chip microcomputer (1): Microchip microcontroller chip, model MCUPIC18F4620-I / PT.
[0036] 2. Drip speed monitoring module (3): Set a drip speed measurement window at the position where the Murphy drip funnel (11) is placed above the dropper limit groove (14) of the main body casing (13), and the infrared pair tube is placed on the measurement window Inside. Based on infrared photoelectric sensing technology, through the infusion droplets passing through the infrared beam to sense the change of the infrared beam, obtain relevant information such as the dynamic droplet flow rate and send it back, and then under the action of amplification, filtering and other circuits, the collected data will be collected through AD digital-to-analog conversion The analog signal ...
Embodiment 2
[0054] Embodiment 2: Preparation of split quick-connect type product of the present invention
[0055] 1. If Figure 4 As shown, the dropper limiting device and the main body are respectively prepared by injection molding the shell (13), and the two shells (13) have a good fit, and the magnetic sucker (17) can be quickly absorbed into one body and is not easy to fall off.
[0056] 2. The drip speed monitoring module (3) and the drip speed control spool (6) are set inside the drip tube limit device.
[0057] 3. The dropper stop device and the main unit adopt a hot-swappable quick-connect port (16) for Unicom work, and the dropper stop device and the main unit adopt a magnetic sucker (17) for fast adsorption combination and are not easy to fall off.
[0058] The present invention prepares example product each component parameter embodiment 1, and according to Figure 4 Structure assembly.
[0059] During the normal infusion process, the dropper stop device and the main machin...
Embodiment 3
[0061] Embodiment 3: the clinical application example of the present invention
[0062] The product prepared according to Example 1 is used for the routine infusion application of patients, and the operation method is as follows:
[0063] 1. Fix the product prepared in Example 1 on the infusion stand, place the Murphy dripping funnel (11) and the infusion pipeline (12) of the infusion set on the left side of the main machine shell (13) and set the dropper limit groove ( 14) Inside.
[0064] 2. Turn on the host and set the dripping speed to 40 drops / minute.
[0065] 3. Disinfect and puncture according to the norms of intravenous infusion care.
[0066] 4. Fix the pulse rate sensor (7) on the patient's index finger, stick the temperature sensor (8) on the patient's forehead, and start the infusion.
[0067] 5. After the droplets flow into the Murphy dropping funnel (11), the drip speed monitoring module (3) automatically starts to monitor the drip speed and enters the servo con...
