Abstract

The invention discloses a nursing device. A pulse measuring mechanism and a dripping speed measuring device are arranged on a bracket; the pulse measuring device comprises a first infrared transmitting tube and a first photoelectric receiving tube which are arranged on the bracket and are respectively positioned on the two sides of a finger of a patient to be measured; the first photoelectric receiving tube is connected with a first amplifying and shaping circuit; the first amplifying and shaping circuit is connected with an analogue-to-digital (A / D) converter; the A / D converter is connected with a calculator; the calculator is connected with a light-emitting diode (LED) display device; the dripping speed measuring device comprises a second infrared transmitting tube and a second photoelectric receiving tube which are arranged on the bracket and are respectively positioned on the two sides of a Murphy's tube to be measured; the second photoelectric receiving tube is connected with a second amplifying and shaping circuit; the second amplifying and shaping circuit is connected with the A / D converter; the A / D converter is connected with the calculator; and the calculator is connected with the LED display device. The nursing device has a reasonable structure, and can rapidly realize pulse measurement and infusion dripping speed count and immediately display measurement results on a display screen with numbers.

Description

technical field [0001] The invention relates to a medical device. Background technique [0002] Clinically, infusion is an important way and basic treatment method for clinical administration. Different ages, different diseases and different medicines require completely different infusion speeds. For example, the elderly and heart disease patients require slower infusion speeds, shock and dehydration. Patients require faster infusion speed; the infusion speed of vasoactive drugs requires very precise infusion speed. When the nurses observe the infusion speed or change the liquid in the ward, the nurse usually counts and adjusts it by looking at the watch. It takes at least 15-30 seconds or even more to clearly count the infusion speed. The disadvantage is that it is time-consuming and imprecise. And labor-intensive. [0003] Pulse measurement includes instantaneous pulse measurement and average pulse measurement. Clinically, average pulse measurement is usually used to ref...
