[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

Embodiment 1
[0040] Such as Figure 2-4 As shown, a pushing mechanism of a needle body 7 for dispensing medicine includes a bracket 1, wherein a slider 4 and a clamping part 5 are slidably provided on the bracket 1, and an elastic part 6 is connected between the slider 4 and the clamping part 5. A needle body 7 is detachably connected to the clamping part 5, and the needle tip 72 of the needle body 7 is flat-bottomed; the slider 4 is driven to move by the driving part, and under the action of the elastic part 6, the slider 4 drives the clamping part 5 Sliding up and down relative to the bracket 1, it is used to insert the needle body 7 into the medicine dispensing bottle or extract it from the medicine dispensing bottle.
[0041] Such as Figure 6 As shown, the above-mentioned needle body 7 is provided with a liquid medicine inflow opening 73 , the opening 73 communicates with the liquid medicine channel 71 in the needle body 7 and extends to the flat bottom surface of the needle tip 72 o...
Embodiment 2
[0046] Such as Figure 7 As shown, the present invention also provides a method for using the pushing mechanism of the needle body 7 for dispensing, including the pushing mechanism of the needle body 7 for dispensing in the above-mentioned embodiment 1, including the following steps:
[0047] Step 1, preparation, connect the needle body 7 pushing mechanism to the catheter and the liquid bag, and place the dispensing bottle under the needle body 7;
[0048] Step 2, push the needle body 7, start the driving part, the driving part drives the slider 4 to move downward, and under the elastic force of the elastic part 6, push the clamping part 5 and the needle body 7 to move downward;
[0049] Step 3: Insert the needle body 7. After the needle body 7 is inserted into the dispensing bottle, the driving part continues to drive the slider 4 to move, under the action of the elastic force of the elastic part 6, until the needle tip 72 of the needle body 7 on the holding part 5 contacts ...

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...
