Problems solved by technology

Since the shape of the droplet is not fixed, and the Murphy dropper is easily affected by pulling, the electric pulse signal output by the photoelectric detection module has interference narrow pulses, especially at the front and rear edges of the droplet electric pulse. Jitter interference pulses , resulting in a decrease in the accuracy of infusion drip velocity detection

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] figure 1 It is a block diagram of an embodiment of an infusion drip speed monitoring device, including a controller unit 11 , a drip speed signal generation unit 12 , a key unit 13 , a display unit 14 , and an alarm unit 15 . The dripping speed signal generation unit 12 converts the dripping speed of the infusion into the counting pulse of the dripping speed and sends it to the controller unit 11; Limit value; the display unit 14 is connected to the controller unit for displaying the upper limit value of the infusion drip speed, the lower limit value of the infusion drip speed and the current actual infusion drip speed; the alarm unit 15 is connected to the controller unit for When the infusion drip speed exceeds the set infusion drip speed upper limit or the infusion drip speed lower limit, it will alarm. The controller unit 11 converts the input drip speed counti...

Abstract

The invention discloses a transfusion dropping speed monitoring device which comprises a controller unit, a dropping speed signal generation unit, a button unit, a display unit and an alarm unit. By adopting the transfusion dropping speed monitoring device, a transfusion dropping speed can be automatically detected and displayed, and an alarm can be made automatically if the transfusion dropping speed exceeds an upper limit or a lower limit; due to adoption of the dropping speed signal generation unit, narrow impulse interference in impulse output from a photoelectric detection module can be automatically filtered off; and the interference impulse filtering effect can be adjusted by adjusting upper limit amplitude of an amplitude limiting accumulation value of the dropping speed signal generation unit or by changing a comparison threshold of the upper limit and the lower limit.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a monitoring device for infusion drop speed. Background technique [0002] Infusion is one of the most basic medical methods. In the process of treating patients with infusion, it is necessary to select the appropriate drip rate of intravenous infusion according to the medicine infused and the patient's condition. At present, the monitoring of intravenous infusion generally adopts a manual method, and the nurse adjusts the speed to an appropriate value according to experience. When the liquid is infused and the dressing is not changed or the needle is pulled out in time, or the needle moves or the infusion tube is folded, etc., air will enter the blood vessel to form an air embolism, blood clots and the needle will be blocked. Constantly observing the infusion situation increases the workload of nurses or accompanying staff. [0003] To detect the dripping speed of th...
