Abstract
The utility model relates to an upright seal off vein indwelling needle, comprising a sheath, an indwelling needle sleeve, a sleeve base, a puncture needle and a needle handle. The sleeve is connected to the sleeve base, and a closing plug and a closing plug conduction bracket are arranged inside the sleeve base back cavity. The puncture needle punctures the closing plug and the hole in the closing plug conduction bracket to the indwelling needle sleeve. By using the utility model, the closing plug can completely shut off the blood bleeding after the indwelling needle is pulling off. When the standard transfusion coupling head is connected, the closing plug conduction bracket is pushed forward so that the taper-shaped tip punctures the closing plug and push off the closing plug needle slot to free the transfusion way to carry out transfusion. The utility model is of simple and professional structure, easy operation and good sealing properties to effectively shut off the blood bleeding, as well as to avoid injures to medical care personnel.

We know that venous detaining needle is a kind of medical apparatus and instruments that is used for the venous indwelling transfusion, and it mainly includes sheath, remaining needle sleeve pipe, casing seat, puncture needle tubing, infusion connector assembly, and the sleeve pipe rear end is connected with casing seat.Straight formula venous detaining needle, extract the puncture needle tubing after, the casing seat rear portion directly is connected with the infusion connector assembly and infuses.In the three way type venous detaining needle casing seat sealing-plug is housed also, the puncture needle tubing was inserted sealing-plug hermetically, was positioned at the remaining needle sleeve pipe, and the casing seat side direction is connected with transfusion three way cock assembly by connecting leg.After medical personnel use venous indwelling at the patient's vein vascular puncture, the needle tubing that will puncture is extracted from casing seat rear end and remaining needle sleeve pipe, comparatively softish sleeve portion is kept somewhere in the patient's vein blood vessel, carries out continuously to the patient or transfusion discontinuously by the remaining needle sleeve pipe.Existing most remaining needle is after extracting puncture needle, and patient's blood can flow out from blood vessel along sleeve pipe, pollutes the site of puncture, even infects medical personnel, to the very big prestige evil of patient and medical personnel's healthy formation.Excessive for preventing blood, medical personnel need push down blood vessel and sleeve pipe with finger when pulling out pin, and operation is inconvenience very, but can not stop the blood outflow fully.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple and reasonable for structure, easy to use, closure is good, can prevent blood seepage flow effectively, the airtight venous detaining needle of straight formula of avoiding it that medical personnel are damaged.
The technical scheme in the invention for solving the above technical problem is: the airtight venous detaining needle of a kind of straight formula, it includes sheath, remaining needle sleeve pipe, casing seat, puncture needle and needle handle, telescopic joint on casing seat, it is characterized in that: casing seat rear portion inner chamber is equipped with sealing-plug and sealing-plug conducting support, puncture needle passes the endoporus of sealing-plug and sealing-plug conducting support, in the remaining needle sleeve pipe, the sealing-plug rear portion is provided with groove, and the tapered front end of sealing-plug conducting support is arranged in the sealing-plug groove.Promoted by extrapolability, it can move forward and strut sealing-plug pin seam.
Sealing-plug axial centre described in the utility model position is provided with the pin seam, puncture needle can therefrom pass easily, when puncture finishes when extracting puncture needle, sealing-plug was from movable sealing when the tip of puncture needle was withdrawed from from sealing-plug, the needle tray seam can seal fully, stops leakage and prevent that blood from flowing out from casing seat; The sealing-plug rear end is provided with the groove of band seam, the degree of depth of groove is consistent with the tapered front end of sealing-plug conducting support, the tapered front end that can hold sealing-plug conducting support, during transfusion, after the transfusion connector at casing seat rear portion inserted the infusion connector of standard, infusion connector matched with sealing-plug conducting support, promoting sealing-plug conducting support moves forward, the tapered front end of sealing-plug conducting support moves forward into sealing-plug, struts sealing-plug pin seam, forms the transfusion path.
Casing seat described in the utility model bottom is provided with double-vane, and casing seat top is provided with the double-vane cross structure of projection.Double-vane and whole remaining needle reliably cosily can be attached on patient's the skin convenient fixing by adhesive plaster.Pushing casing seat when the double-vane cross structure of casing seat upper lobes is just operated with medical personnel uses.
This utility model is owing to be equipped with sealing-plug and sealing-plug conducting support at casing seat rear portion inner chamber, against existing technologies, medical personnel are after extracting the retained needle puncture needle assembly, sealing-plug has been blocked the blood outflow fully, behind the connection standard infusion connector, strut sealing-plug pin seam by sealing-plug conducting support, make infusion path unimpeded, realize transfusion smoothly.This utility model is simple and reasonable for structure, operation, easy to use, and closure is good, can prevent the blood outflow effectively, avoids it that medical personnel are damaged.
