Description
Technical field
The utility model is related to a kind of puncture needle.
Background technology
Existing puncture needle, intensity is not high, is easily snapped off when puncturing；
In addition, when the lid to bottle (container such as reagent bottle or Reagent Tube) is punctured, due to inner and outer air pressure difference
In the presence of liquid can be caused can not to suction out or inject；Although many puncture needles are all that air bleed slot is provided with the outside of pin on the market,
Processing and use environment are had higher requirements, the requirement of balanced seal sampling pipe inner and outer air pressure is extremely difficult to.
Moreover, existing puncture needle, liquid injection port is arranged on point, easily block, cause fluid injection or draw decoction failure.
Therefore, it is necessary to design a kind of new puncture needle.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of puncture needle, and the puncture needle structure is ingenious, and intensity is high,
It is not easily broken, it is easy to implement.
The technical solution of utility model is as follows：
A kind of puncture needle, including outer pin and interior pin；Outer needle guard is on interior pin；The front end of interior pin is used to puncture provided with one
Point；
At least one interior needle cannula is provided between interior pin and outer pin；
The front end of interior pin is provided with the interior needle cannula described in one.
Interior needle cannula is at least two, and one of them interior needle cannula is arranged on the rear end of interior pin.
Have between interior pin and outer pin every dead band；Sealed between interior pin and outer pin；The tube wall of outer pin provided with air admission hole and
Steam vent；Air admission hole and steam vent are connected with every dead band.
Air admission hole is located at the front end of outer pin, and steam vent is located at the rear end of outer pin.
Air admission hole and steam vent are multiple.Multiple air admission holes or steam vent is set to prevent wherein some or multiple quilts
Block, such as blocked by bottle cap.
Length direction of multiple air admission holes along outer pin is equidistantly arranged；Length direction of multiple steam vents along outer pin is equidistant
Arrangement.
Outer pin is provided with 3 steam vents and 3 air admission holes.Can also be 2-6 steam vent or 2-6 air admission hole.
Described puncture needle also includes pin fixed block, and interior pin and outer pin are each attached on pin fixed block.
Described point is the solid member of closing.Inlet opening is not opened up on point.
The sidepiece of interior pin front end is provided with inlet opening, and inlet opening is located at the rear of point.
The front end of outer pin has the transition of arc or slope shape.
Beneficial effect：
Puncture needle of the present utility model, bottle cap or bottle stopper (generally quality of rubber materials) for penetrating sample tube or reagent bottle
Plastic bottle closure is sampled, and puncture needle two ends are designed with sleeve pipe, for strengthening interior pin intensity, it is ensured that pin does not bend change penetrating bottle cap
Shape；Air admission hole and steam vent are set on outer pin, when pin pierces into sample tube, air inlet pipe in sample tube, steam vent outside sample tube,
Gas is discharged from stomata in sample tube, makes sample tube inside and outside air pressure balance, is improved and is inhaled sample accuracy；Needle tip closing is beneficial to wear
Saturating bottle cap, it is not easy to block pin hole and produce rubbish；Interior pin is connected the air tight no leakage of sealing with outer pin.Sum it up, this wear
Pricker compact conformation, penetrates function by force, is not easily broken, easy to use, is adapted to promotion and implementation.
