Description

Technical Field

[0001] The invention relates to a flow rate detection and control device for a medical infusion tube, and in particular to an automatic flow rate detection and control device and method for a medical infusion tube. Background Art

[0002] Medical infusion tubes, commonly known as disposable intravenous infusion sets in medicine, are one of the important medical consumables that have been sterilized. It is mainly used to establish a channel between the vein and the liquid medicine to achieve intravenous infusion to meet the patient's treatment needs. Medical infusion tubes are generally composed of multiple components connected, including intravenous needles or injection needles, needle caps, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, bottle stopper punctures, air filters, etc. Some infusion sets are also equipped with additional functional components such as injection parts and dosing ports. Under the action of atmospheric pressure, the liquid in the bottle flows into the drip bucket along the thinner infusion hose. When the water column pressure of the drip bucket is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. The flow rate regulator is used to control the infusion speed of the liquid to ensure the accuracy of the infusion and the comfort of the patient.

[0003] Traditional infusion flow rate regulators mainly rely on mechanical principles to control the infusion speed. These regulators usually squeeze the infusion line by sliding buttons or rotating regulators to change the size of the liquid diameter. According to the principles of fluid dynamics, the larger the diameter, the smaller the resistance generated by the pipeline and the faster the flow rate; conversely, the smaller the diameter, the greater the resistance and the slower the flow rate.

[0004] However, when using traditional infusion flow rate regulators, they can generally only be adjusted mechanically, and cannot achieve stepless adjustment. The adjustment range and accuracy are limited. Therefore, to a certain extent, the ability of medical staff to make fine adjustments based on the patient's specific condition and the properties of the drug is limited. In addition, during use, due to limited adjustment accuracy and a single adjustment method, traditional infusion flow rate regulators are prone to infusion speeds that are too fast or too slow, thereby increasing the risk of adverse reactions in patients.

[0062] The integrated sensor 1.4 monitors the flow rate of the liquid medicine in the infusion tube in real time and transmits the data to the intelligent control system in the control unit in real time. The intelligent control system controls the flow rate of the liquid medicine in the infusion tube by adjusting the distance between the first baffle 1.2 and the second baffle 2.5 according to the preset flow rate range.

[0063] If there is no liquid medicine flowing in the infusion tube, the intelligent control system will immediately trigger the warning light 2.2 to warn, and automatically adjust the distance between the first flow blocking member 1.2 and the second flow blocking member 2.5 to achieve automatic blocking. In addition, when the device needs to be disassembled, it is only necessary to press the key pad 6.4 in the reset member 6, and the reset bolt 6.2 will push out the positioning pin 2.9 located in the through hole 1.9, thereby easily releasing the lock between the fixed frame mechanism 1 and the fixed cover mechanism 2.
