Needle body pushing mechanism for medicine dispensing and using method

Abstract

The invention discloses a needle body pushing mechanism for medicine dispensing and a using method. The needle body pushing mechanism comprises a support. A sliding block and a clamping component are arranged on the support in a sliding mode. An elastic component is connected between the sliding block and the clamping component. A needle body is detachably connected to the clamping component. The end of a needle point of the needle body is in a flat bottom shape. The sliding block is driven by a driving component to move. Under the effect of the elastic component, the sliding block drives the clamping component to slide up and down relative to the support, and therefore the needle body is inserted into the body of a medicine dispensing bottle or drawn out of the body of the medicine dispensing bottle. The using method of the pushing mechanism comprises the steps of carrying out preparation, pushing the needle body and inserting the needle body to the bottom of the medicine dispensing bottle. According to the pushing mechanism, the sliding block, the clamping component and the elastic component between the sliding block and the clamping component are arranged on the support, the needle body can be inserted into bottoms of medicine dispensing bottles of different specifications and lengths under the push effect of the clamping component for suction, the end of the needle point of the needle body is not damaged, the structure is simple, medicine dispensing is convenient, the medicine dispensing efficiency can be effectively improved, and the application range is wide.

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
