Abstract
The utility model relates to structural improvement of a blood taking needle. The structural improvement of the blood taking needle comprises a needle handle, a needle body and a needle cap, wherein a needle frame groove is formed in the needle handle. The needle handle and the needle cap are of an integral injection molding structure. The connecting portion of the needle handle and the needle cap is a separating portion of the needle handle and the needle cap. The needle body extends into the needle cap. The structural improvement of the blood taking needle is characterized in that a crescent-shaped groove is formed in the needle cap of the connecting portion of the needle cap and the needle handle, a cone-shaped boss is arranged on the end face of the needle handle, corresponding to the position of the groove, and the cone-shaped boss is connected with the crescent-shaped groove in a plastic mode. On one hand, the structural improvement of the blood taking needle can shorten the length of the needle body exposed outside, and reduces pain of needle entering. On the other hand, the structural improvement of the blood taking needle improves intensity between the needle body and the needle handle, improves concentricity between the needle body and the needle handle to prevent the needle body from being taken away or loosening when the needle cap and the needle handle are separated. A cone-shaped structure is adopted, so that the structural improvement of the blood taking needle has the advantages of facilitating demolding actual manufacture, reducing binding area with the needle cap, and improving separating effect. In addition, the structural improvement of the blood taking needle has the advantages of being simple in structure, reasonable in design, beautiful in appearance and the like.
Description
Technical field
This utility model belongs to blood taking needle manufacturing technology field, particularly relates to a kind of architecture advances of blood taking needle.
Background technology
at present, the blood taking needle that adopts in tip blood collecting technology field mainly comprises needle handle, needle body and pin cap, described needle handle is provided with the punch block groove, described needle handle and pin cap are integrated injection structure, described needle handle and pin cap junction are the separated part of needle handle and pin cap, described needle body extends in the pin cap, the structure of described pin cap is circular, wherein the end face of the junction needle handle of pin cap and needle handle is planar structure, such problem can appear in the Practical manufacturing process, the pin cap with after needle handle separates again the end face of needle handle still have residual, cause the pin cap to separate unclean with needle handle and pollution that cause, in addition, according to effective depth of needle of actual clinical blood taking needle in the 1.2mm left and right, if pain long that cause is stronger, if when Practical manufacturing just with the tip position of needle body design 1.2mm left and right, adhesion with the pin cap will be affected so, in order to overcome the problems referred to above, the following technical scheme of ad hoc meter, this technical scheme has solved above-mentioned technical problem.
Summary of the invention
This utility model provides a kind of simple in structure, reasonable in design, pain when reducing blood sampling for solving the technical problem that exists in known technology, improve come off when reality the is used architecture advances of clean blood taking needle of product.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
A kind of architecture advances of blood taking needle, comprise needle handle, needle body and pin cap, described needle handle is provided with the punch block groove, described needle handle and pin cap are integrated injection structure, described needle handle and pin cap junction are the separated part of needle handle and pin cap, and described needle body extends in the pin cap, it is characterized in that: the junction pin cap of described pin cap and needle handle is provided with crescent shaped groove, the end face of the described needle handle in respective slot position is provided with cone boss, and described cone boss plasticity connects crescent shaped groove.
This utility model can also adopt following technical measures:
The excircle of described punch block groove is provided with reinforced pier.
Cone boss junction on the bottom of described crescent shaped groove and needle handle end face be provided with the needle handle end face on the symmetrical cone boss of cone boss.
Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme, namely be provided with crescent shaped groove on the pin cap of the junction of pin cap and needle handle, the end face of the described needle handle in respective slot position is provided with cone boss, described cone boss plasticity connects crescent shaped groove, can shorten the exposed length of needle body so on the one hand, reduce the pain of inserting needle; On the other hand, improve the intensity between needle body and needle handle, improve the concentricity between needle body and needle handle, prevent from needle body being taken out of or being become flexible when pin cap and needle handle disengaging, adopt pyramidal structure also to be convenient to the demoulding when Practical manufacturing, reduce simultaneously the adhesion area with the pin cap, improved the advantage of separating effect.In addition, this utility model also has the advantages such as simple in structure, reasonable in design, good looking appearance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A cutaway view in Fig. 1;
