Needle pushing mechanism for dispensing medicine and method of use

Abstract

Provided are a needle-body push mechanism for dispensing medicine, and a method for use thereof; the needle-body push mechanism comprises a frame (1); the frame (1) is slidingly provided with a slider (4) and a clamp member (5); a flexible member (6) is connected between the slider (4) and the clamp member (6); a needle body (7) is detachably connected to the clamp member (5), and the end part (72) of the tip of the needle has a flat-bottomed shape; the slider (4) is driven to move by means of a driving member; under the effect of the flexible member (6), the slider (4) drives the clamp member (5) to slide upward and downward with respect to the frame (1), and is used for inserting the needle body (7) into a medicine-dispensing bottle body or pulling it out of the medicine-dispensing bottle body; the method for using the push mechanism comprises preparing, pushing the needle body (7), and inserting the needle body (7) into the bottom of the medicine-dispensing bottle. In the push mechanism, a slider (4) and a clamp member (5) are slidably arranged on a frame (1), and a flexible member (6) is arranged between the slider (4) and clamp member (5); under the pushing effect of the clamp member (5), the needle body (7) may be inserted, for suction, into the bottoms of medicine-dispensing bottles having different specifications and lengths without damaging the end part (72) of the tip of the needle body (7); the structure is simple and dispensing medicine is convenient, improving medicine-dispensing efficiency, and the invention is widely adaptable.

Description

technical field [0001] The invention relates to the field of medical device dispensing, in particular to a needle pushing mechanism for dispensing and a method for using it. Background technique [0002] At present, in the field of medical dispensing, for example, when dispensing injections in ampoules or vials, it is necessary to use dispensing devices such as syringes to fit the dispensing needles in order to suck out the medicinal liquid. Most of the existing dispensing needles adopt figure 1 As shown, it includes a needle body 101 with a needle tip 102 at one end and a needle head 103 at the other end. A liquid medicine channel 104 is provided in the needle body. In order to facilitate insertion and extraction, the needle point 102 is designed as a sharp end; because the needle point 102 is a sharp shape, the sharp section is generally longer, about 3-8 mm, therefore, in order to avoid damaging the sharp part of the needle point 102 when dispensing medicine, generally av...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the existing needle tip of the existing dispensing needles in the prior art as a sharp part. When dispensing medicine, no matter whether the medicine is dispensed by holding the needle body or holding the needle body with mechanical claws, in order to avoid damage to the needle body, it is impossible to The needle body is inserted into the bottom of the ampoule or vial, and the ampoule or vial needs to be tilted to draw more thoroughly, which brings the above-mentioned shortcomings of troublesome dispensing and low dispensing efficiency. A needle body pushing mechanism for dispensing and its use are provided. method
