Embodiment 1

[0030] Example 1 Injection molding method of degradable infusion set three-way valve / dosing device:

[0031] The first step, vacuum drying: vacuum-dry the degradable substrate pellets of formula 1, formula 2 or formula 3 at 50-55° C. for 4 hours, and set aside.

[0032] The second step, injection molding: add the dried degradable substrate pellets of formula 1, formula 2 or formula 3 to an injection molding machine for injection molding.

[0033] The barrel temperature is set as: feed inlet 155-165°C, compression section 160-170°C, metering section 160-175°C, nozzle 155-170°C;

[0034] Mold temperature: 20-30°C;

[0035] Injection pressure: 55-90Mpa;

[0036] Injection time: 40-45 seconds;

[0037] Pressure holding time: 0-4 seconds;

[0038] The screw speed is: 180 rpm;

[0039] Obtain the infusion set three-way valve / dosing device that adopts the degradable base material of formula 1, formula 2 or formula 3 to make.

[0040] The above-mentioned embodiment has described...

Abstract

The present invention provides a degradable material for an infusion apparatus three-way valve / doser and a manufacturing method. The degradable infusion apparatus three-way valve / doser is prepared by a degradable polymer ingredient of a degradable substrate and an enhancer. The injection molding process includes that: a feed inlet is of 155-165 DEG C, a compression segment is of 160-170 DEG C, a metering segment is of 160-175 DEG C, a nozzle is of 155-170 DEG C, the mold temperature is 20-30 DEG C, the injection pressure is 55-90 Mpa, the injection time is 40-45 seconds, the dwell time is 0-4 seconds, and the screw speed is 180 r / min. So the degradable infusion apparatus three-way valve / doser is obtained. The used degradable infusion apparatus three-way valve / doser does not need burning, and can completely biodegrade by landfill in the natural environment to achieve low-carbon, energy-saving and environmental-protection purposes.

Description

technical field [0001] The invention relates to the technical field of bioengineering of medical devices, in particular to a degradable material and a preparation method for a three-way valve / dosing device of an infusion set. Background technique [0002] The "three-way valve / dosing device" of the existing disposable infusion set is all made of non-degradable petroleum-based plastics, because of its relatively cheap price, especially the "three-way valve / dosing device" as a disposable The accessories of the infusion set are widely used for one-time use to prevent cross-infection of diseases, etc., but after decades of clinical practice, it has been proved that there are many problems in the "three-way valve / dosing device" of the plastic disposable infusion set. It is well known that after use, it needs to be recycled and incinerated, and plastics will produce a lot of black smoke when incinerated, and at the same time release toxic and carcinogenic substances such as hydroge...
