Description

Multiple Flow Regulators for Single Use Infusion Pumps

technical field

The utility model relates to the technical field of medical equipment, in particular to a multi-flow regulator for a disposable infusion pump.

Background technique

Currently clinically used multi-flow regulators for disposable infusion pumps all have a single flow rate, such as 2 milliliters per hour or 5 milliliters per hour. During use, once a certain flow rate is selected, it cannot be changed. However, in actual clinical use, it is often necessary to change the amount of fluid given according to the treatment conditions of different patients. However, current single-use infusion pumps cannot meet this function.

For example, in 2013, the patent publication No. CN203634574U discloses a self-control liquid supply device for a disposable infusion pump, which is characterized in that: the device includes an upper cover, a lower cover, a liquid inlet, a liquid outlet, and an exhaust valve. , a two-way joint, a tee pipe and a small liquid bag, the liquid inlet is communicated with the two-way joint, and the two-way joint is connected with a pipeline one and a pipeline two, and the pipeline one passes through the small The liquid bag is also connected to the branch pipe of the three-way pipe; the second pipeline is connected to the main pipe of the three-way pipe, and a silicone tube is provided at the junction of the main pipe of the three-way pipe and the branch pipe. This utility model can't according to the treatment situation of different patients, or the pain tolerance of patient's self adds the fluid volume.

In 2015, the patent publication No. CN104721910 disclosed a multi-flow rate controller for an analgesic pump, including: a flow tube; press the wall of the flow tube to change the cross-section area of the flow tube; the inlet tube communicates with the flow; and the outlet tube communicates with the flow tube. This patent can achieve flow regulation to a certain extent, but the flow regulation is likely to cause inaccurate drug administration during use. In clinical applications, due to strict restrictions on drug use, this patent still has a lot of room for improvement.
