Embodiment Construction

[0031] The present invention is mainly realized by improving the needle structure of operation needles such as the existing infusion bottle intake needle (referred to as the intake needle), the infusion bottle dripping needle (referred to as the bottle insert needle), and the dispensing dilution injection needle (referred to as the dispensing needle). The purpose of the invention.

[0032] For the needle structure of the working needle of the present invention, see Figure 5 As shown, first of all, the needle tip of the needle 1 is no longer closed but in an open state. The front end of the needle 1 is provided with a second inclined surface 12 close to the needle tip and a first inclined surface 11 thereafter. The first inclined surface 11 is a needle tube 14 (see Figure 3A~3C ), the first inclined surface 11 and the wall of the needle tube 14 are between 15 degrees, and the second inclined surface 12 is between 18 degrees and the wall of the needle tube; wherein, the entire edge...

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...
