Embodiment 1

[0023] Such as figure 1 As shown, a multi-stage flow control device applied to an infusion pump includes a valve body 1, the valve body 1 has a cylindrical valve cavity 2 that penetrates up and down, and the valve body 1 is also provided with side passages A3, Side channel B4 and side channel C5, the inlet ends of the side channel A3, side channel B4 and side channel C5 communicate with the middle end of the valve chamber 2 in turn from top to bottom, and the side channel C5, side channel B4 and side channel The outlet port of A3 communicates with the lower end of the valve chamber 2 respectively; the upper and lower ends of the valve body 1 are respectively provided with a protrusion A6 and a protrusion B7 communicating with the valve chamber 2, and the cavity cross-sectional area of ​​the protrusion A6 is smaller than that of the valve body. The cross-sectional area of ​​the cavity 2, the cavity of the protrusion A6 and the valve cavity 2 are connected with a valve stem, the...

Embodiment 2

[0030] Such as Figure 5As shown, a multi-stage flow control device applied to an infusion pump includes a valve body 1, the valve body 1 has a cylindrical valve cavity 2 that penetrates up and down, and the valve body 1 is also provided with side passages A3, Side channel B4 and side channel C5, the inlet ends of the side channel A3, side channel B4 and side channel C5 communicate with the middle end of the valve chamber 2 in turn from top to bottom, and the side channel C5, side channel B4 and side channel The outlet port of A3 communicates with the lower end of the valve chamber 2 respectively; the upper and lower ends of the valve body 1 are respectively provided with a protrusion A6 and a protrusion B7 communicating with the valve chamber 2, and the cavity cross-sectional area of ​​the protrusion A6 is smaller than that of the valve body. The cross-sectional area of ​​the cavity 2, the cavity of the protrusion A6 and the valve cavity 2 are connected with a valve stem, the...

Abstract

The invention relates to an infusion pump assembly, in particular to a multi-level flow control device applied to an infusion pump. Through cooperation among arc-shaped protrusions, an upper groove, amiddle groove and a lower groove, a liquid outlet is matched with a lateral channel A, a lateral channel B and a lateral channel C, and therefore flow adjustment is achieved. The device has the advantages that the structure is simple, control is simple, microscale accurate control and supply of medicine are achieved, multi-level flow control can also be achieved, and clinical use requirements aremet.

Description

technical field [0001] The invention relates to an infusion pump assembly, in particular to a multistage flow control device applied to the infusion pump. Background technique [0002] The infusion pump, also known as the analgesic pump, maintains a timely and stable concentration of analgesic drugs in the blood plasma, and allows the patient to press the drug by himself to quickly enhance the effect and make the treatment more individualized. 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] The infusion pump is a micro-infusion device that injects drugs at a certain speed, in a small amount, continuously and evenly through the control of the flow-limiting device by means of infusion power. The infusion power forms mainly include mechanical elastic force and electric drive. For ex...
