Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of protection patient life security, the protection type malleation remaining needle of avoiding remaining needle to be polluted.
Technical background
Along with the raising of people's living standard, the remaining needle less to blood vessel injury has been widely used in clinical.Remaining needle is a kind of medical apparatus and instruments for the venous transfusion treatment, and remaining needle is easy and simple to handle, is applicable to the puncture at any position, has alleviated the misery of patient's repeated localised puncture simultaneously, has alleviated nursing staff's workload, is protected deeply clinically to suffer from and welcomes.When clinical use, puncture needle leads the remaining needle sleeve pipe to enter the vein blood vessel of human body.After seeing blood back, confirm the venipuncture success, puncture needle is extracted out, and only the remaining needle sleeve pipe of material softness is retained in the vein blood vessel.Medicinal liquid is by remaining needle sleeve pipe input human body.The remaining needle sleeve pipe adopts softness to have certain elastic material and makes, can in the safe indwelling time of human vein, use, and crooked synchronously with vein with people's limb motion, make the injection site still can freely move, do not have the anxiety of thorn perforating veins.So just avoided frequent puncture to cause suffering to the patient.
Yet find that in clinical manipulation when medical personnel used remaining needle, puncture needle was very likely stabbed medical personnel.In addition, the remaining needle operated by rotary motion has the threeway positive pressure connector, to make things convenient for the patient can fail two kinds of medicinal liquids simultaneously, wherein the long duct joint links to each other with thimble assembly by long duct, infusion connector generally is exposed to the outside when not using, dispose helmet on the side cone joint, and be three to five days the service time that remaining needle is general, therefore infusion connector is easy to bacterial infection, threatens patient's life security.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of patient's life security of can protecting, the protection type malleation remaining needle of avoiding remaining needle to be polluted.
The purpose of this utility model is achieved in that this remaining needle comprises the needle tubing assembly in suit and the thimble assembly, the threeway positive pressure connector that links to each other with thimble assembly by long duct, wherein, thimble assembly comprises sleeve pipe, sleeve pipe is connected with the threeway casing seat by metal wedge, one end of threeway casing seat is connected with notch needle tubing suit in the needle tubing assembly by batching pig, the other end links to each other with long duct, the needle tubing assembly comprises the notch needle tubing, the notch needle stand, the threeway positive pressure connector comprises the conduit Connection Block that is connected with long duct, the conduit Connection Block links to each other with cone joint respectively at infusion connector by triple-valve body, be disposed with sealing ring between triple-valve body and the infusion connector, spring and spool; Tongs is installed on the long duct, and protective sleeve is equipped with in the outside of sleeve pipe, and the length of protective sleeve is greater than the length of notch needle tubing, and the outer cover of cone joint is equipped with the end cap of usheing to seat, and the end cap top of usheing to seat is provided with the Bacteria-prevention cap seat, and the Bacteria-prevention cap seat is connected with the Bacteria-prevention cap suit.Described cone joint with usher to seat between the end cap to being threaded.Described end cap and the Bacteria-prevention cap seat of usheing to seat is structure as a whole.
The utlity model has simple in structure, cost is low, thereby can avoid remaining needle to be polluted threatening the advantage of patient's life security.
