In a word, this take detention needle of positive pressure valve structural design is reasonable, can effectively prevent the backward flow of blood, has made things convenient for the medicine that adds, is fit for using widely.
Description
Technical Field
The utility model relates to a take delay needle of positive pressure valve belongs to medical supplies technical field.
Background
The retention needle is a needle head which can be repeatedly used for a plurality of times after once puncturing a blood vessel when a transfusion bottle is used for a long time, can relieve the pain of a patient caused by a plurality of injections, and is particularly suitable for the patient with edema. After the conventional retention needle is used, in the process of pulling out the infusion line, blood can flow back to the retention needle due to the absence of the positive pressure valve.
In order to solve the technical problem, the utility model discloses a take delay needle of positive pressure valve, this take delay needle of positive pressure valve and positive pressure valve between be in the same place through catheter connection, be equipped with the liquid stopping clamp on the catheter, the liquid stopping clamp can make liquid flow temporarily, make things convenient for the operation of syringe needle, be equipped with the silica gel sealing member in the inlet of positive pressure valve, the inlet of positive pressure valve is equipped with the external screw thread outward, the existence of positive pressure valve can make the in-process that the transfer line was extracted on the delay needle keep the malleation, avoided blood to flow backwards to in the delay needle, be equipped with the pencil on the side of positive pressure valve, the pencil has made things convenient for the joining of medicament, be equipped with sealing cap on the pencil, sealing cap can play effective guard action to the pencil. In a word, this take detention needle of positive pressure valve structural design is reasonable, can effectively prevent the backward flow of blood, has made things convenient for the medicine that adds, is fit for using widely.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a take needle that is detained of positive pressure valve, includes syringe needle, catheter and positive pressure valve, its characterized in that: the syringe needle with the positive pressure valve between link together through the catheter, be equipped with on the catheter and end the liquid clamp, be equipped with the silica gel sealing member in the inlet of positive pressure valve, the inlet of positive pressure valve is equipped with the external screw thread outward, be equipped with on the side of positive pressure valve and add the pencil, be equipped with sealed cap on the pencil.
The utility model discloses a take delay needle of positive pressure valve, this take delay needle of positive pressure valve and positive pressure valve between link together through the catheter, be equipped with only the liquid clamp on the catheter, only the liquid clamp can make liquid flow temporarily, make things convenient for the operation of syringe needle, be equipped with the silica gel sealing member in the inlet of positive pressure valve, the inlet of positive pressure valve is equipped with the external screw thread outward, the existence of positive pressure valve can make the in-process that the transfer line was extracted on the delay needle keep the malleation, blood has been avoided flowing backwards to in the delay needle, be equipped with the pencil on the side of positive pressure valve, the pencil has made things convenient for the joining of medicament, be equipped with sealed cap on the pencil, sealed cap can play effective guard action to the pencil. In a word, this take detention needle of positive pressure valve structural design is reasonable, can effectively prevent the backward flow of blood, has made things convenient for the medicine that adds, is fit for using widely.
