Drop type infusion control system

Abstract

The invention discloses a drop type infusion control system which comprises a dropping liquid sensing component, an infusion tube flow control component and a control module. The dropping liquid sensing component is arranged on one side of a dripping kettle and is higher than the liquid level in the dripping kettle and can monitor liquid drops dropping into the dripping kettle and calculate a time interval t between two adjacent liquid drops. The infusion tube flow control component is arranged on one side of an infusion tube at the lower end of the dripping kettle and can control the opening size of an inner cavity of the infusion tube at the lower end of the dripping kettle through squeezing. The control module sets the range of the time interval t, and when the time interval t exceeds a set range, the control module controls the infusion tube flow control component to increase or reduce opening and closing spaces of the inner cavity of the infusion tube, so that the time interval t is within the set range. According to the drop type infusion control system, an infusion bottle / infusion bag can be switched automatically.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an infusion bottle / infusion bag fixation, puncturing, and bottle changing device and a drop-type infusion control system composed of the same. Background technique [0002] Liquid drip infusion is the method of injecting medicinal liquid into the human vein by utilizing the principle of pressure difference (gravity) generated by liquid head drop, which is a common method for clinical rescue and treatment of patients. [0003] The work of intravenous infusion for many years has been operated, monitored and cared by medical personnel manually. Due to the uncertainty of environmental factors in manual operations, such as dust, fiber bacteria, viruses or other particles in the air, these uncertain environmental factors will cause imperceptible changes in the liquid medicine when medical staff perform infusions and switch bottles. Pollution has a negative impact on clinical drug safety...

AI Technical Summary

Problems solved by technology

[0007] During the infusion process, there is no equipment on the market that can control the temperature of the infusion solution well. There is only one simple heating rod on the existing market to heat the temperature of the infusion liquid; moreover, it is a one-time heater, which cannot be used repeatedly to waste a lot of
