Abstract
The utility model relates to a once used syringe needle, belonging to medical instruments. The utility model is formed by that a needle stick which is provided with a needle tip, a blood observation window, and a needle plug are connected in sequence and are connected into integration. When the utility model is operated, the phenomenon of backflow of the blood can be observed through the blood observation window, and the pollution that the blood is sucked into the inner cavity of the syringe is avoided.
Description
This utility model belongs to medical apparatus.
The present used syringe needle of each medical institutions is to be joined successively by needle point and pin stalk and pintle to constituting one, during use, after medical personnel were thrust muscle with syringe needle, piston was drawn in examination, checked whether intravasation of syringe needle, as when taking out piston, when loseing the blood extraction, know that then syringe needle not in blood vessel, can push medicinal liquid, extract out if any blood, then should change the injection site, this moment, the syringe inner chamber was contaminated, caused cross infection easily.In addition, a kind of disposable syringe is arranged still now, though it can avoid cross infection, its cost is higher, and just by whole jettisonings, this is waste material not only after using, and bring white elephant economically can for the patient.
The purpose of this utility model is to provide a kind of disposable aspiration needle.
The purpose of this utility model is achieved in that the pin stalk that is provided with needle point and blood observation window and the pintle formation one of joining successively.
This utility model can directly have been found not blood back phenomenon for medical personnel because of between pin stalk and pintle a blood observation window being set when operating, do not make blood be inhaled into the inner chamber of syringe, pollutes, and syringe still can continue to use, to save equipment.
Concrete structure of the present utility model is described further in conjunction with the accompanying drawings.
Fig. 1 is this utility model structure chart.
The pintle 4 that is provided with the pin stalk 3 of needle point 1 and is provided with blood observation window 2 is through being injection molded into one, and needle point 1 and pin stalk 3 can select for use steel to manufacture, and blood observation window 2 and pintle 4 can select for use transparent plastic to manufacture.
Claims (1)
- A kind of disposable aspiration needle, being joined successively by needle point 1 and pin stalk 3 and grouping 4 constitutes, and it is characterized in that being provided with blood observation window 2 between pin stalk 3 and the pintle 4.
