Miniature intelligent drip controller

Abstract

The invention provides a miniature intelligent drip controller, which comprises mechanical executing parts, a control module, a sensor, an illuminating module, lampshades, buttons and a shell. The control module, through information acquired by the sensor, is used for controlling the mechanical executing parts so as to achieve whole-process control over the automation of entire infusion without human intervention. By adopting the combination of a steering engine and a cam to drive a bolt, a purpose of independently controlling each of a plurality of infusion tubes is achieved through the rotating range of the steering engine within 180 degrees, and with the control of the control module, selection among a plurality of modes is achieved; for example, the controller can monitor a patient who is subjected to multiple bottles of drips in order and can simultaneously monitor the one-to-one infusion mode of multiple patients, and the controller can adopt different alarm forms in accordance with the different modes since the controller detects the completion of the infusion so as to facilitate distinguishing; therefore, the working efficiency is greatly improved and the labor intensity of doctors and nurses is reduced. In addition, the drip controller, which is provided with a power supply and the illuminating module, can conduct normal infusion activities under the circumstance without a light source and the power supply.

Description

Technical field [0001] The invention relates to medical equipment, in particular to a miniature intelligent drip controller. Background technique [0002] The current drip controllers are mainly divided into two categories. The first type relies on a DC motor and a matched screw nut to convert the rotary motion into a linear motion, pushing a flat cone head and clamping the infusion tube in cooperation with the infusion tube slot to lock the infusion tube to control the infusion. The second type relies on the solenoid valve to directly drive the flat cone head to cooperate with another flat cone head to lock the infusion tube to control the infusion. The above two types of controllers have many defects. Among them: the first type of DC motor is bulky and consumes a lot of power, so it is difficult to achieve miniaturization and light weight, and can only be used in a fixed manner, which limits the use occasion; the rotation motion is converted to linear motion through the coope...

AI Technical Summary

Problems solved by technology

Among them: the first type of DC motor is bulky and consumes a lot of power, so it is difficult to achieve miniaturization and light weight. Slow response slows down, and this structure directly leads to the fact that one motor can only control one infusion tube at the same time, and multiple infusion tubes can only be controlled by multiple motors separately, which is very expensive

The second type uses a solenoid valve, which is bulky and consumes a lot of power, making it difficult to miniaturize and lighten

The locking action can only be performed after the solenoid valve is energized. Once the power is cut off or the power supply fluctuates, the locking action cannot be maintained, so it is not safe.

Using a solenoid valve to lock the infusion tube also has the problem that one solenoid valve can only control one infusion tube at the same time. When multiple infusion tubes need to be controlled, multiple solenoid valves are required, which is very expensive
