Micro-infusion multi-flow control device and disposable infusion pump

Abstract

The invention discloses a micro-infusion multi-flow control device. The micro-infusion multi-flow control device comprises a base, a flow control member, a spring and a fixing member. The base is provided with a piston cavity. The closed end of the piston cavity is provided with a plurality of circularly distributed liquid outlets. The flow control member is provided with at least one front-back through runner. The front end of the flow control member is provided with a piston head and is fitted into the piston cavity of the base, and the rear end of the flow control member is provided with an operating handle. The runner can be in one-to-one but joint with the liquid outlets when the flow control member rotates. The fixing member is arranged at the open end of the piston cavity and is provided with a rotary positioning structure matching with the flow control member. The spring is sleeved to the flow control member. One end of the spring is supported on the piston head of the flow control member, and the other end of the spring is supported on the fixing member. The control device allows for multi-position control for the flow of a disposable infusion pump, so that the clinical application requirement is met. The invention discloses the disposable infusion pump with the control device.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a micro-infusion multi-flow control device of a disposable infusion pump. The invention also relates to a disposable infusion pump provided with said control device. Background technique [0002] With the development of clinical medical technology and the improvement of pharmaceutical technology, more and more intravenous drugs (such as anesthetics, analgesics, etc.) need to be continuously infused during or after the operation. [0003] At present, disposable infusion pumps have been widely used for continuous injection of patients in clinical micro-infusion therapy (such as intravenous, subcutaneous), and are also widely used for postoperative analgesia, chronic pain treatment, malignant tumor analgesia and other Treatment with minimal continuous infusion of liquid medicine is required. [0004] Disposable infusion pump is a micro-infusion device that uses infusion po...

AI Technical Summary

Problems solved by technology

[0006] Since the flow rate of the disposable infusion pump is small, which belongs to the trace level, and the flow control is relatively difficult, most of the existing disposable infusion pumps do not have the function of flow adjustment, or only have the function of simple flow conversion, which cannot meet the needs of the patients. clinical use requirements
