This utility model is realized by following approach:

The needle stand of flexible protective sleeve is installed, is comprised housing and holder, holder is fixedly mounted on an end of housing, and its structural feature is, also includes a pipe box, and the one end is fixedly mounted on the holder, and an end of needle tubing is fixedly plugged in the other end of pipe box.

Between holder and needle tubing, has a pipe box like this, this pipe box one end is fixed, the other end, and just free end then connects needle tubing, like this when needle tubing is done the time spent, even needle tubing length is long, the stress on the needle tubing at first acts on the free end of pipe box, bears the stress that the needle tubing motion is brought by pipe box, because the diameter of section of pipe box is big than needle tubing, can select the strong material of toughness, even so pipe box be subjected to big stress also to be not easy to rupture, safe and reliable; The degree of freedom of needle tubing just becomes big in addition, uses more flexible.

This utility model can further be specially:

The length that needle tubing is socketed in the pipe box is 10%～80% of pipe box length.

The length that needle tubing is socketed in the pipe box is 10%～50% of pipe box length.

The length that needle tubing is socketed in the pipe box is 10%～30% of pipe box length.

Needle tubing is socketed in the length scale in the sleeve pipe, depends on the length of needle tubing self, and needle tubing length is long more, and its length that is socketed in the sleeve pipe should be long more.For medical needle now commonly used, as remaining needle etc., the length that general needle tubing is socketed in the pipe box is 10%～30%.

This technical scheme is also brought a unexpected technique effect: because the length of needle tubing was shorter, length difference is by the pipe box substituting, the material of needle tubing always needs high-quality, high-tech rigid material to make, its cost is high a lot of more than pipe box, after the part of needle tubing is replaced by pipe box, in the accumulation of amount, can save sizable cost, also save resource simultaneously.

The length of pipe box is 50%～120% of needle stand shell length.

But the shell length of the length needle stand of pipe box and actual needs and decide generally will be more than 10mm, and for medical needle commonly used now, as remaining needle, its length should be suitable with the needle stand shell length, or longer than needle stand shell length.

The pipe box inner chamber has one deck viscose glue, and itself and needle tubing are firmly affixed.

One end of needle tubing need be prevented coming off of needle tubing by affixed, damages, and therefore adopts viscose glue to come the cementation needle tubing it to arrive better fixation.

This utility model can also further be specially:

One side of needle stand housing has a flank, and an end of this flank is fixedlyed connected with this housing.

The flank effect is to provide user the manual position of convenience, makes the use of pin convenient and simple.

Be connected with a needle tubing protective sleeve on the pipe box; this protective sleeve is made up of a plurality of tubular structures; these a plurality of tubular structures, and can be stretched and compress to the big tubular structure socket successively of sectional area in regular turn by the little tubular structure of sectional area, can coat whole needle tubing after the stretching.

In use, the needle tubing protective sleeve is a compressive state, can be compressed in the inner chamber of needle stand; after the use, be the exposed user of stabbing of needle point that prevents needle tubing, the needle tubing protective sleeve stretches and opens; until coating whole needle tubing, needle point is limited in the protective sleeve, have more safety with regard to the use that makes pin like this.

The needle tubing protective sleeve can further be specially:

Be connected with a valve pocket on the free end of the tubular structure of sectional area maximum, this valve pocket is a column structure, has a valve constitution in its inner chamber, and the internal diameter of valve pocket is identical with the external diameter of the tubular structure of sectional area maximum.

After protective sleeve stretches and coats whole needle tubing, expose once more outside the protective sleeve for preventing needle point, the valve arrangement in the valve pocket can stop the activity of needle point, thereby further guarantees the safety that pin uses.

Valve pocket can also further be specially:

The cross section internal diameter of valve pocket is identical with the cross section external diameter of needle stand.

Because protective sleeve can wholely be compressed in the inner chamber of needle stand, valve pocket can and connect with needle stand, as a kind of retaining valve; in addition because the cross section internal diameter of valve pocket is identical with the cross section external diameter of needle stand; the erection space of whole needle set is dwindled, make easier for installationly, installation cost reduces greatly.

In sum, advantage of the present utility model is, a kind of needle stand that flexible protective sleeve is installed is provided; this needle stand uses a pipe box to connect needle tubing, has strengthened the freedom of movement of needle tubing, makes it not easy fracture; strengthened the security reliability that needle set uses, also made the use of needle set have more flexibility ratio in addition.In addition, also has a unexpected technique effect, that is: the material of needle tubing always needs high-quality, high-tech rigid material to make, its cost is high a lot of more than pipe box, after the part of needle tubing is replaced by pipe box, in the accumulation of amount, can save sizable cost, also save resource simultaneously.
