Abstract
The utility model discloses a vein remaining needle hemostasis sealing plug. The front part of the sealing plug is cut with a cutting mark with the maximum breadth smaller than the diameter of the sealing plug along the axial direction; the rear part of the sealing plug is cut with a cutting mark with the width smaller than that of the cutting mark at the front part along the same cutting face at front part. The utility model has the advantages of simple structure, convenient utilization, good sealing, which is able to prevent blood seeping effectively.
Description
Technical field
This utility model relates to a kind of hemostatic seal plug of vein-retaining needle.
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 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, because left pin hole of puncture needle or pin seam is arranged on the sealing-plug, it is unreliable to seal, patient's blood can flow out from blood vessel along sleeve pipe easily, pollute the site of puncture, even infect medical personnel, to patient and medical personnel's the big harm of healthy formation machine.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 also are to stop the blood outflow fully.
Summary of the invention
This utility model purpose is: a kind of hemostatic seal plug of vein-retaining needle is provided, and the sealing plug structure is simple, easy to use, good airproof performance, can prevent blood seepage flow effectively.
The technical solution of the utility model is: a kind of hemostatic seal plug of vein-retaining needle, the front portion of sealing plug is cut the cut channel of a Breadth Maximum less than the sealing-plug diameter vertically, the rear portion of sealing-plug along the front portion same tangent plane cut the cut channel of a width less than anterior cut channel.
The further technical scheme of this utility model is: a kind of hemostatic seal plug of vein-retaining needle, the front portion of sealing plug is cut the cut channel of a Breadth Maximum less than the sealing-plug diameter vertically, the rear portion of sealing-plug along the front portion same tangent plane cut the cut channel of a width less than anterior cut channel; The forward cut channel of described sealing-plug vertically is half elliptic, and semielliptical minor axis is positioned at the front end face of sealing-plug, and semielliptical major axis is positioned on the axis of sealing-plug, and the cut channel at sealing-plug rear portion is vertically rectangular, and the orthogonal axial length of side is far longer than the radially length of side.
The more detailed technical scheme of this utility model is: a kind of hemostatic seal plug of vein-retaining needle, the front portion of sealing plug is cut the cut channel of a Breadth Maximum less than the sealing-plug diameter vertically, the rear portion of sealing-plug along the front portion same tangent plane cut the cut channel of a width less than anterior cut channel; The forward cut channel of described sealing-plug vertically is half elliptic, and semielliptical minor axis is positioned at the front end face of sealing-plug, and semielliptical major axis is positioned on the axis of sealing-plug, and the cut channel at sealing-plug rear portion is vertically rectangular, and the orthogonal axial length of side is far longer than the radially length of side; The middle part of described sealing-plug outer surface is provided with a ring groove.
This utility model advantage is:
1. the cut channel at forward cut channel of this utility model and rear portion is convenient to passing of puncture needle, and puncture needle passes Shi Buhui and takes buffings out of, the safe and sanitary when having guaranteed operation.
2. when extracting puncture needle, the cut channel at forward cut channel of this utility model and rear portion can be sealed pin hole immediately, and sealing is reliable, and patient's blood can not flow out from blood vessel along sleeve pipe, has avoided that the site of puncture is contaminated, medical personnel are infected.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the longitudinal sectional view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Wherein: 1 cut channel (front portion); 2 cut channels (rear portion); 3 ring grooves.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2 and shown in Figure 3, a kind of hemostatic seal plug of vein-retaining needle, the front portion of sealing plug is cut the cut channel 1 of a Breadth Maximum less than the sealing-plug diameter vertically, the rear portion of sealing-plug along the front portion same tangent plane cut the cut channel 2 of a width less than anterior cut channel 1; The middle part of sealing-plug outer surface is provided with a ring groove 3.
The forward cut channel 1 of sealing-plug vertically is half elliptic, and semielliptical minor axis is positioned at the front end face of sealing-plug, and semielliptical major axis is positioned on the axis of sealing-plug, and the cut channel 2 at sealing-plug rear portion is vertically rectangular, and the orthogonal axial length of side is far longer than the radially length of side.
The cut channel 2 at forward cut channel 1 of this utility model and rear portion is convenient to passing of puncture needle, and puncture needle passes Shi Buhui and takes buffings out of, the safe and sanitary when having guaranteed operation; When extracting puncture needle, the cut channel 2 at forward cut channel 1 of this utility model and rear portion can be sealed pin hole immediately, and sealing is reliable, and patient's blood can not flow out from blood vessel along sleeve pipe, has avoided that the site of puncture is contaminated, medical personnel are infected.
The annular protrusion that is provided with in the ring groove 3 at this utility model outer surface middle part and the casing seat cooperates, and is used for hemostatic seal plug stably is fixed in the Injector Bushing base.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within this utility model scope required for protection.
