Intravenous injection liquid flow rate display device based on nursing teaching

Abstract

The invention discloses a nursing teaching intravenous injection-based liquid flow rate display device, which comprises a mounting bracket and an infusion apparatus, the infusion apparatus comprises a drip bottle, the bottom of the drip bottle is communicated with a hose, the upper part of the hose is provided with a drip chamber, and the top of the mounting bracket is provided with a hook for hanging the drip bottle. The upper portion of the installation support is provided with an amplification display assembly used for measuring the flow velocity of liquid, a display belt is connected between the two rotating wheels, the surface of the display belt is provided with a plurality of projection areas, and the projection areas can be used for receiving refraction light spots of a laser transmitter. By means of the arranged amplification display assembly, when the liquid level of the drip chamber changes, refracted light rays generated by the laser transmitter can form light spots on a projection area and move up and down, and within a certain time, the flow speed of intravenous injection at the moment can be visually obtained through the change of the up-down distance of the light spots.

Description

technical field [0001] The invention relates to the technical field of intravenous injection, in particular to a liquid flow rate display device based on intravenous injection in nursing teaching. Background technique [0002] In the traditional teaching process, nursing teachers and students in professional colleges and universities need to use traditional clocks to count and calculate the flow rate of the intravenous fluid flow rate. The existing assessment of new teachers is based on feeling, and cannot be used. Intuitively see the current speed. During the assessment process, teachers cannot judge the flow rate very well. They rely more on experience to judge whether the current student's operation meets the requirements. Therefore, a nursing-based teaching method is now provided. Intravenous fluid flow display device. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a liquid flow rate display device based on intravenous injection o...

[0002] In the traditional teaching process, nursing teachers and students in professional colleges and universities need to use traditional watch clocks to count and calculate the flow rate of the intravenous fluid flow rate. The existing assessment for new teachers is based on feeling, and cannot Intuitively see the current speed, in the assessment process, the teacher can not judge the flow rate very well, more rely on experience to judge whether the current students' operation meets the requirements, so here is a nursing teaching based Liquid flow rate display device for intravenous injection
