The pressure sensor detects the pressure change in the infusion tube and feeds back the pressure change to the microcomputer system, and when the pressure change drops to an alarm value preset by the microcomputer system, the microcomputer system sends a signal to the alarm device to prompt and alarm, so that the situations of blood backflow and the like caused by too low pressure in the infusion tube are prevented. The ultrasonic wave bubble sensor detects bubbles existing in the infusion tube, and when the bubbles are detected to be generated and the volume of the bubbles is larger than a preset alarm value of the microcomputer system, the microcomputer system sends a signal to the alarm device to prompt and alarm, so that the phenomenon that the bubbles with overlarge volume are input into a human body to cause harm to the human body is prevented.
The infrared drop number sensor 131 comprises an infrared transmitting tube and a photosensitive receiving tube, wherein the two ends of the infrared transmitting tube and the photosensitive receiving tube are oppositely arranged, when the medicine drops, the light intensity is weakened, so that the voltage change of the photosensitive receiving tube is caused, the dropping of the medicine liquid is judged according to the voltage change of the photosensitive receiving tube, the number of the drops of the medicine liquid is counted, and the transfusion speed of the infrared drop number sensor can be displayed on a display screen damaged by a fixing frame.
Calculating the infusion speed of the infrared drop number sensor:
the number of milliliters (ml/h) input per hour is (number of drops per minute) × 60)/drop coefficient (drop/ml), the drop coefficients commonly used in China are three types, namely 10 drops/ml, 15 drops/ml and 20 drops/ml, the drop coefficient is 10 drops/ml for example, and the number of milliliters (ml/h) input per hour is (number of drops per minute) × 6.
Specifically, the infrared drop number sensor records the number and rate of drops of the medical fluid in the drip chamber, compares the number and rate of drops with the infusion rate input by the pump device, and adjusts the infusion rate of the pump device. The specific adjustment scheme is as follows: the difference value between the infusion speed of the pump device of the infusion pump in the initial working state and the infusion speed recorded by the infrared drop number sensor is set, and the difference value between the infusion speed of the pump device and the infusion speed recorded by the infrared drop number sensor is not accurate enough due to certain error of the infusion speed of the pump device after a period of use, so that when the difference value between the infusion speed of the pump device and the infusion speed recorded by the infrared drop number sensor is too large, the microcomputer system can adjust the infusion speed of the pump device based on the infusion speed of the infrared drop number sensor and the set difference value, and then calibration is carried out.
Referring to fig. 4, as shown in the figure, the infrared transmitting tube and the photosensitive receiving tube of the infrared drop number sensor are mounted on the fixing frame 3, the infrared transmitting tube and the photosensitive receiving tube are mounted on the upper half portion of the drip cup, and the fixing frame 3 is provided with a visible window 31. The position of the fixed frame is 10cm-20cm away from the position of the pump device, so that the metering position of the infrared drop number sensor is a certain distance away from the pumping position of the pump device, and the metering accuracy of the infrared drop number sensor and the pumping position of the pump device is ensured. Meanwhile, the visible window arranged on the fixing frame can clearly observe the height of the liquid level in the drip cup, so that the liquid level is prevented from being too high, and the transfusion safety is prevented from being influenced.
The pressure sensor monitors the pressure in the infusion tube, and the prior art such as patent CN201610757166.7 can be adopted to prevent the problems of blood backflow, empty bottle conveying and the like, when abnormal conditions occur, the pressure sensor feeds back to the microcomputer system in time, and the microcomputer system sends a signal to the alarm device to finish abnormal alarm work until the abnormality is removed.
The ultrasonic wave bubble sensor monitors bubbles in the infusion tube, prevents bubbles influencing the safety of a human body from being input into the human body, and can adopt the prior art such as patent CN201521019977.4 and the like to prevent large bubbles from being input into the human body, timely feed back to a microcomputer system when abnormal conditions occur, and the microcomputer system sends a signal to an alarm device to finish abnormal alarm work until the abnormality is removed.
It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present patent.
