Description
Technical field
This utility model relates to disposable syringe, particularly extracts medicinal liquid for clinical device puncture bottle stopper and uses, and can avoid pricking wound clinically and reduce the disposable use needleless bottle plug puncture unit that pollutes.
Background technology
The nurse is abideing by doctor's advice in the patient injection process, need need the preparation injecting drug use according to doctor's advice at different patient schemes.And in the process of making up a prescription, need to use syringe, i.e. dispenser.Common dispenser generally all is with pin, and in use, medical personnel's plug that pin need be punctured may cause pricking wound, and the use of needle tubing, has introduced the risk of needle tubing to liquid medicine contamination again.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of disposable use needleless bottle plug puncture unit, avoids the pricking wound risk and reduces the pollution of needle tubing to medicinal liquid.
In order to address the above problem the technical solution of the utility model is such:
Disposable use needleless bottle plug puncture unit is characterized in that, comprising:
The bottle stopper puncture needle has a puncture on the described bottle stopper puncture needle body, has a filler port in the body, has a filler in puncture, and this filler and described filler port one end connect, the other end opening of described filler port;
One dosing connector has the stepped hole of a hollow in the described dosing connector, described dosing connector is threaded with described bottle stopper puncture needle;
An one sealing plug and a spring, sealing plug and spring are installed in the stepped hole of described dosing connector, and an end of described spring props up described bottle stopper puncture needle body, and the other end withstands the sealing plug, to seal up an end of described stepped hole.
After preventing that the bottle stopper puncture needle from inserting bottle stopper, from bottle stopper, extract repeated use again, described puncture is provided with agnail.
Spring of the present utility model adopts taper spring, and a wherein large diameter end props up described bottle stopper puncture needle body, and an end of minor diameter withstands described sealing plug.Adopt taper spring, can apply a higher power, thereby guarantee that the sealing plug can seal up dosing connector well to the sealing plug.
This utility model dosing connector is provided with the locked groove that is connected with the infusion apparatus that has the external taper joint, and infusion apparatus can be connected with dosing connector stabilized seal ground.
During use, the bottle stopper puncture needle is inserted in the Plastic bottle plug, then syringe or other are had the infusion apparatus of external taper joint, insert or be screwed on the dosing connector, push away the sealing cork downwards, the sealing of sealing cork and dosing connector is opened, and spring is compressed accumulation of energy, heparin or other liquid can normally be annotated like this, and the liquid of filling is input in the plastic bottle by filler port in the bottle stopper puncture needle and filler.After filling finishes, take off syringe or other has the infusion apparatus of external taper joint, spring is released, and forces the sealing plug to come back to original sealing station, and the liquid in the plastic bottle just can not leak out like this.
This utility model is avoided the pricking wound risk and is reduced the risk of needle tubing to liquid medicine contamination owing in use need not the participation of needle tubing.
Description of drawings
Describe this utility model in detail below in conjunction with the drawings and specific embodiments.
