Embodiment 1

[0027] Example 1 Injection molding method of environmentally friendly, energy-saving and degradable disposable infusion set needle:

[0028] The first step is vacuum drying: the degradable substrate pellets of formula 1 or formula 2 are vacuum dried at 52°C for 5 hours, and then set aside.

[0029] The second step, injection molding: add the dried degradable substrate pellets of formula 1 or formula 2 into the hopper of the injection molding machine for injection molding.

[0030] The temperature of the barrel is set as: 150°C at the inlet, 155°C in the compression section, 165°C in the metering section, 170°C in the nozzle;

[0031] The mold temperature is: 20℃;

[0032] The injection pressure is: 75pa in the first section, 80Mpa in the second section, and 50Mpa in the third section;

[0033] Injection cycle: 45 seconds;

[0034] Holding time: 0 seconds;

[0035] The screw speed is: 180 rpm.

Abstract

The invention provides an environment-friendly and energy-saving biodegradable type disposable infusion device thrusting needle and a preparation method thereof. The environment-friendly and energy-saving biodegradable type disposable infusion device thrusting needle is formed by proportioning biodegradable macromolecular main ingredients and enhancers of biodegradable base materials. The injection molding process includes that the temperature of a feed inlet is 145-160 DEG C, the temperature of a compression section is 155-165 DEG C, the temperature of a metering section is 160-175 DEG C, and the temperature of a nozzle is 165-175 DEG C; the temperature of a mould is 10-20 DEG C; the injection pressure is 50-80 Mpa; the injection period is 41-52 seconds; the dwell time is 0 second; and the screw speed is 180 turns per minute. Thus, the environment-friendly and energy-saving biodegradable type disposable infusion device thrusting needle can be manufactured, the thrusting needle does not need to be incinerated after being discarded and can be absolutely biodegraded in the natural environment through landfill, and therefore the purposes of saving energy and protecting environment and human health are achieved.

Description

Technical field [0001] The invention relates to the technical field of bioengineering of medical devices, in particular to an environmentally friendly, energy-saving and degradable disposable infusion set needle and a manufacturing method. Background technique [0002] "Disposable infusion set needle", one end is connected with the infusion tube of the infusion set, and the other end is used to insert the tube of the infusion bag to connect the infusion channel. Commonly used disposable infusion set (straight hole plastic pin ), disposable blood transfusion set (side-hole plastic pin), such as the patent No. 01256294.7 "the bottle pin in the disposable infusion set", the existing "disposable infusion set pin", it is not possible to use ABS etc. It is made of degradable petroleum-based plastics, but after decades of clinical practice, it has been proved that plastic disposable infusion set needles need to be burned together after use. When the plastic is burned, a large amount of ...
