Embodiment 1

[0017] Embodiment 1 Preparation and use of a polymethyl methacrylate transfusion chip

[0018] A three-channel dispensing infusion chip, made of polymethyl methacrylate, the structure of the chip is designed as follows: figure 1 As shown, the preparation method is as follows: first, use computer-aided design software to design and draw the microchannel pattern in the microfluidic chip; then, process the required microchannel on the surface of the polymethyl methacrylate substrate through the numerical control lathe processing technology ( 2) and mixing channels (3), while processing drug inlets (1) and outlets (4) on the polymethyl methacrylate cover sheet; finally aligning the substrate with the channel structure and the cover sheet with fluid inlets and outlets After bonding, thermal bonding completes the preparation of the infusion chip. Among them, the width of the channel is 0.5 mm, the depth is 0.3 mm, the diameter of the inlet and outlet is 3 mm, and the length, width ...

Embodiment 2

[0020] Embodiment 2 Preparation and use of a polycarbonate transfusion chip

[0021] A dual-channel drug dispensing infusion chip is made of polycarbonate, and the structure of the chip is designed as follows: figure 1 As shown, the difference is that the number of drug inlets is 2, and the chip preparation method is as follows: first, use computer-aided design software to design and draw the microchannel graphics in the microfluidic chip; Process the required channels on the surface of the sheet, and process the drug inlet and outlet on the polycarbonate cover sheet; finally, after aligning the base material and the cover sheet, thermal bonding completes the preparation of the infusion chip. Among them, the width of the channel is 1 mm, the depth is 0.5 mm, the diameter of the inlet and outlet is 2 mm, and the length, width and thickness of the chip are 70 mm, 30 mm and 5 mm, respectively.

Abstract

The invention provides an infusion chip and a production method thereof. The infusion chip comprises a drug inlet, a passage, a fluid mixing unit, and an outlet. When the infusion chip is used for compounding drugs and infusion, different drug solutions can be automatically mixed in the infusion chip only by guiding in the different drug solutions from the drug inlet of the chip, and drug compounding and infusion can be performed for patients by guiding out the mixed drug solutions from the outlet. The infusion chip is convenient to operate, low in material cost and processing cost, suitable for batch production of disposable infusion sets, and has predictable great market value.

Description

technical field [0001] The invention relates to an infusion device, in particular to an infusion chip and a preparation method thereof. Background technique [0002] Infusion is a commonly used medical method, and infusion sets based on plastic infusion tubes are widely used in medical institutions today. But the infusion set used at present is basically a single-channel infusion set, and each use is limited to the infusion of a kind of medicine. However, in reality, there are many occasions where simultaneous infusion of multiple drugs is required. For example, when infusing amino acids and fat emulsion, the infusion of fat emulsion needs to be more than 6 hours, and it is better to combine the infusion with amino acids for better effect. In these occasions, it is necessary to develop simple and easy multi-channel infusion devices, such as "Y-shaped infusion set" [Chinese invention patent, application number 200910229841.9] and "medicine dispensing infusion set" [Chinese ...
