Abstract

The utility model discloses a non-needle connecting retaining needle, which comprises a canula, a retaining pinhead in the front of the canula and one or a plurality of channels are arranged at the connector in the back of the canula. Envelop means is arranged at the port of the connector, envelop means comprises a connecting sleeve of which the front end is fixed with the connector and the back end is connected to the injector or the transfusion apparatus. Connecting sleeve is provided with seal sleeve of which the front end is open communicated with the connector and back end is provided with cut. The utility model can be connected to the injector or the transfusion apparatus without an injector, which avoids the phenomenon that the sufferer is infected by the germy needle. At the same time, the screw connecting between the connecting sleeve of the remain needle and the injector or transfusion apparatus is more reliable and prevents the turn between the injection end and the connecting sleeve and guarantees the injection efficacy.

Description

Needleless interconnection system remaining needle
Technical field
This utility model relates to a kind of medical apparatus, relates in particular to the remaining needle that uses on the clinical medicine.
Background technology
Venous detaining needle is as the regeneration product of scalp draw point, be widely used in clinical, its advantage more and more by the nursing staff cognition.
The advantage of venous detaining needle has: (1) venous indwelling needle cannula is made by advanced person's biomaterial Vialon, and sleeve pipe softness, toughness be big, be difficult for the injured blood vessel wall and cause and exosmose that its leakage rate is below 13.8%.(2) venous indwelling is stabbed for a short time at blood vessel, protects blood vessel effectively, and tube drawing reduces the destruction to blood vessel after of short duration reparation is promptly reusable.(3) venous detaining needle has reduced the patient's blood vessel puncture time, has alleviated patient's misery, has alleviated nurse's workload.(4) trocar retention time in blood vessel is longer, can accomplish venous transfusion at any time for patients such as operation, neonate, critical, rescues, guarantees treatment.(5) economical price of the trocar equates both economical practicality substantially with common scalp draw point transfusion consumptive material.
Present remaining needle comprises remaining needle head part, conduit and has the connector of one or more passages.One end of conduit is connected with the remaining needle head part, and the other end of conduit is communicated with connector, and the port of connector generally is equipped with calparine cap and seals.
But the dispensing end that syringe that is connected with such remaining needle or transfusion device need the band entry needles inserts in the calparine cap, if inject entry needle has antibacterial before injection after, be easy to cause that the phenomenon of patient infection's disease produces again.In addition, between existing syringe, transfusion device and the calparine cap be connected and unreliable.
Summary of the invention
This utility model purpose is: a kind of needleless interconnection system remaining needle is provided, this remaining needle need not entry needle when being connected with syringe or transfusion device, avoided because of the carry disease germs generation of the phenomenon that causes patient infection's disease of entry needle, syringe, transfusion device adopt the mode that is spirally connected to be connected with the fitting sleeve of remaining needle simultaneously, make connection more reliable, prevent the rotation between dispensing end and the fitting sleeve, guaranteed the injection effect.
The technical solution of the utility model is: a kind of needleless interconnection system remaining needle, comprise conduit, the front end of conduit is communicated with the remaining needle head part, the rear end of conduit is communicated with the connector with one or more passages, the port of connector is provided with pipe sealing device, described pipe sealing device comprises fitting sleeve, the front end and the connector of fitting sleeve are fixed, the rear end of fitting sleeve can connect syringe or transfusion device, be provided with sealing shroud in the fitting sleeve, the sealing shroud front opening, opening is communicated with connector, the back end closure of sealing shroud seals and is provided with otch.
The further technical scheme of this utility model is: a kind of needleless interconnection system remaining needle, comprise conduit, the front end of conduit is communicated with the remaining needle head part, the rear end of conduit is communicated with the connector with one or more passages, the port of connector is provided with pipe sealing device, described pipe sealing device comprises fitting sleeve, the front end and the connector of fitting sleeve are fixed, the rear end of fitting sleeve can connect syringe or transfusion device, be provided with sealing shroud in the fitting sleeve, the sealing shroud front opening, opening is communicated with connector, the back end closure of sealing shroud seals and is provided with otch; The endoporus rear end of described fitting sleeve is provided with step, the diameter of the fitting sleeve inwall of the diameter of the fitting sleeve inwall before the step after greater than step, the rear end outer wall of sealing shroud and the rear end inwall of fitting sleeve closely cooperate, and the rear end face of sealing shroud and the rear end face of fitting sleeve are in the same plane.
The more detailed technical scheme of this utility model is: a kind of needleless interconnection system remaining needle, comprise conduit, the front end of conduit is communicated with the remaining needle head part, the rear end of conduit is communicated with the connector with one or more passages, the port of connector is provided with pipe sealing device, described pipe sealing device comprises fitting sleeve, the front end and the connector of fitting sleeve are fixed, the rear end of fitting sleeve can connect syringe or transfusion device, be provided with sealing shroud in the fitting sleeve, the sealing shroud front opening, opening is communicated with connector, the back end closure of sealing shroud seals and is provided with otch; The endoporus rear end of described fitting sleeve is provided with step, the diameter of the fitting sleeve inwall of the diameter of the fitting sleeve inwall before the step after greater than step, the rear end outer wall of sealing shroud and the rear end inwall of fitting sleeve closely cooperate, and the rear end face of sealing shroud and the rear end face of fitting sleeve are in the same plane; The outer wall of described fitting sleeve rear end is provided with external screw thread.
This utility model advantage is:
1. this utility model need not entry needle when being connected with syringe or transfusion device, has avoided because of the carry disease germs generation of the phenomenon that causes patient infection's disease of entry needle.
2. this utility model adopts the mode that is spirally connected to be connected with syringe, transfusion device, makes connection more reliable, has prevented the rotation between dispensing end and the fitting sleeve, has guaranteed the injection effect.
