Continuous infusion device for automatically switching infusion channel sequence

Abstract

The invention relates to a continuous infusion device for automatically switching infusion channel sequence, comprising a puncturing device (1), an infusion switch (2), an infusion hose (3), a Maffeitube (5), a flow rate regulator (6), a pharmaceutical liquid filter (7) and an intravenous infusion needle (8), wherein the continuous infusion device further comprises a controller (4). The infusionswitch (2) is used for controlling the infusion lines of a plurality of infusion bags, the controller (4) utilizes the float slide valve as the driving force with buoyancy and gravity as the driving force, realizes the automatic switching of the multi-infusion channels through the clever mechanical structure, achieves the sequential continuous infusion of the multi-infusion bags without manual intervention, and has the automatic exhaust effect, further prevents the accidental occurrence. The infusion device is simple in structure, stable in control and low in cost, and is very suitable for popularizing and using in medical institutions such as hospitals, so as to reduce the workload of medical workers and improve efficiency.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an infusion set which can automatically switch infusion channels and realize continuous infusion according to a certain infusion sequence. Background technique [0002] Intravenous infusion is a commonly used treatment method in clinical treatment. In clinical treatment, patients often need to infuse multiple different medicinal solutions, and these medicinal solutions require a certain infusion sequence according to the doctor's order. The common infusion set that adopts for intravenous infusion can't realize the continuous infusion of medicinal liquid at present, often needs to transfuse a bag of medicinal liquid earlier, open the infusion switch of next bag of medicinal liquid by the nurse or change infusion bag. Waste a lot of time and manpower like this, cause the workload of medical staff to increase. In the process of opening the next bag of medical solution or changing th...

Problems solved by technology

The main problem of this regulating dropper is: the vertical infusion channel of the sliding valve core is a closed space, the valve core is difficult to slide up and down due to the difficulty of exhaust, and the air coming in from the infusion bag during the infusion process cannot be discharged in time to cause danger; Sequential continuous infusion can be realized, but the structure of the device is complex, and the assembly of the electromechanical modules will cause the device to be too large and require additional energy consumption

The main disadvantage of this infusion head is that after the first bag of liquid medicine is infused, the liquid level in the automatic liquid control room of the infusion head under the infusion bag at the back may drop, causing the valve to open, so that each bag of liquid medicine in the back will be closed. outflow, the reliability of sequential infusion becomes worse; in actual use of this device, each infusion bag needs an infusion head, which is expensive, cumbersome and unreasonable
