Abstract
The utility model discloses a kind of syringe anti-pollution injector needle, comprise pin stalk, pintle and needle point, the top of described pintle is provided with annular groove, and the pintle in annular groove is provided with deflector, and described deflector is multiple and is distributed on the outer surface of pintle.This utility model by be arranged on the groove on pintle top can effectively stop operator take out add medicinal liquid process herb liquid from needle point flow out pollute.
Description
Technical field
This utility model relates to and belongs to medical apparatus and instruments, relates in particular to a kind of syringe anti-pollution injector needle.
Background technology
The nipple of the ordinary syringe of current clinical use is connected not bery tight with the pintle of syringe needle, the two easily separates, and needs operator's the fixing pintle of forefinger, to prevent the two separation in dosing process.Forefinger contacts the pollution that has caused pintle with pintle.Taking out while adding medicinal liquid, be easy to medicinal liquid to discharge needle point, flow to the pollution that causes medicinal liquid on pintle.In the time that the medicinal liquid of our preparation need to aspirate repeatedly (as 100 milliliters of SHENMAI ZHUSHEYE are added to 250 ml physiological salines), contaminated medicinal liquid can flow into foul solution in sterile solution along pin stalk, contaminated solution easily causes the complication such as infection after being input in patient body, and patient is caused to injury again.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, a kind of syringe anti-pollution injector needle that can effectively stop backflow medicinal liquid to cause sterile solution to pollute.
This utility model is achieved through the following technical solutions:
A kind of syringe anti-pollution injector needle, comprises pin stalk, pintle and needle point, and the top of described pintle is provided with annular groove, and the pintle in annular groove is provided with deflector, and described deflector is multiple and is distributed on the outer surface of pintle.
The utility model has the advantages that: this utility model by be arranged on the groove on pintle top can effectively stop operator take out add medicinal liquid process herb liquid from needle point flow out pollute.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Embodiment: syringe anti-pollution injector needle as shown in the figure, comprise pin stalk 1, pintle 4 and needle point 5, the top of described pintle 4 is provided with annular groove 3, and the pintle 4 in annular groove 3 is provided with deflector 2, and described deflector 2 is multiple and is distributed on the outer surface of pintle 4.Take out the medicinal liquid being flowed out by needle point 5 places while adding medicinal liquid and flow in the annular groove 3 on pintle 4 tops through pin stalk 1, can stop like this medicinal liquid to continue toward dirty, avoided the medicinal liquid flowing out to contact with contaminated pintle 4.Can reduce patient in the process of medication due to the former of operator thereby the infection that causes.
