Medicine bottle operation needle and processing method thereof

Abstract

The invention relates to a medicine bottle operation needle and a processing method thereof, which relate to the field of medical apparatuses. The medicine bottle operation needle comprises a syringe needle and a needle tube, wherein the syringe needle is provided with a second bevel close to a needle point, a first bevel on the rear of the second bevel, and an inner bevel inclined inwards within 50 to 70 percent of an area of the whole edge of an opening of the first bevel and the edge of an opening of the second bevel which is connected with the first bevel; and the operation needle can be an infusion bottle dropping funnel needle, an infusion bottle air inlet needle or a dispensing diluting needle. The processing method for the operation needle is to grind two-thirds of the wall thickness of the needle tube again to form the inner bevel on the basis of grinding to form the first bevel and the second bevel. The operation needle processed by the method has a novel structure, is smooth to insert, can completely stop pollution of rubber stopper particles under the condition of medicine supply through stems, reduces infusion reaction, improves the use efficiency and the safety of the operation needle, and is a novel generation of product of the medicine bottle operation needle.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a needle structure suitable for dispensing and diluting injection needles, bottle insertion needles and air intake needles and a processing method thereof. Background technique: [0002] Intravenous infusion is a common basic nursing operation in clinical practice, and it is also an important method for the hospital to treat and rescue patients. In the dispensing process of intravenous infusion, dispensing dilution injection needles, infusion sling drop needles, and infusion sling inlet needles are widely used, which are collectively referred to as "operation needles" in the present invention. Among these types of needles, the infusion bottle dropper needle and the infusion bottle inlet needle basically act on the stopper of the medicine bottle and do not contact the human body. Generally, there is a specification of Φ1.6×30mm infusion bottle dropper needle, Φ1. 6×35mm infusion sling bottle air in...

Problems solved by technology

[0011] Fourth, when preparing intravenous drip medicine, the rubber stopper often blocks the needle tube to produce rubber stopper particles in the liquid, which will seriously affect the quality of the drug.
