Infusion bracket

Abstract

The invention discloses an infusion bracket which comprises a first vertical bracket, a first horizontal bracket, a second horizontal bracket, a second vertical bracket and a power measuring device. The first horizontal bracket is connected with the first vertical bracket through a bearing and can rotate up and down in a vertical plane. The second horizontal bracket is connected to the first vertical frame and is located under the first horizontal bracket. The second vertical bracket is fixedly connected below the first horizontal bracket and is located under the second horizontal bracket. A pressure sensor for measuring pressure signals is arranged on the second horizontal bracket. The tail end of the second vertical bracket is placed on the pressure sensor. The power measuring device comprises a pressure sensor, an A / D (Analogue to Digital) conversion module, a controller, a display screen, an alarm and a button. The infusion bracket provided by the invention can amplify gravity of an infusion bag manyfold by means of lever principle and converts the gravity to pressure of the pressure sensor, the A / D conversion module can convert the pressure signal to a digital signal, the controller can calculate the digital signal and displays the result on a display screen, and quantitive alarm can be set through the button and the alarm. The infusion bracket provided by the invention can quantitively analyze the infusion process, and is high in precision and strong in antijamming capability.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to an infusion stand. Background technique [0002] The infusion speed of the patient during infusion is generally adjusted by the nurse based on the experience of the dripping speed, which often cannot be accurately adjusted to the infusion speed suitable for the patient, making the patient less comfortable during the infusion process. In addition, when the patient is infused, it is generally necessary for the medical staff to observe the remaining infusion volume at any time, and remove the infusion device from the patient when the remaining infusion volume is not much, so it is inconvenient to manually observe the remaining infusion volume at any time . At present, the detection device used for medical infusion generally adopts an infrared pair tube, that is, an infrared light-emitting diode and an infrared receiving photosensitive transistor are respectively install...

AI Technical Summary

Problems solved by technology

This detection method is susceptible to changes in ambient light and water mist in the muffier dropper

In addition, there is a method to calculate the infusion speed by measuring the weight of the infusion bag in real time, but because each drop of the infusion is very small and weighs very little, this method of directly measuring the weight change of the infusion bag has low measurement accuracy
