Abstract
The utility model relates to a vein indwelling needle tampon, which is mounted inside a sleeve seat for an indwelling needle and shaped in a cylinder. Front part of the utility model is uniformly cut into two halves along its axial line. In its rear part, a cut mark in width smaller than diameter of the cylinder is punched in the center of the same cutting face as that in the front part. Thus, a gap that is integrally cut and the cut mark that is partially punched make for putting puncture needles through, and moreover, no silica-gel fabrics will be brought out when the puncture needles go through. When the puncture needles are removed, the gap, which is cut open on the tampon, and the punched cut mark can immediately seal the needle holes with reliable air tightness. The utility model is characterized in simple & reasonable structure, convenient operation & utilization and perfect air tightness. Bleeding outside can be prevented effectively and injure to paramedics can be avoided.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of hemostatic seal plug of vein-retaining needle.
Background technology
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, 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 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, provides a kind of simple and reasonable for structure, easy to use, and closure is good, and sealing is reliable, can prevent the hemostatic seal plug of vein-retaining needle of blood seepage flow effectively.
The technical scheme in the invention for solving the above technical problem is: a kind of hemostatic seal plug of vein-retaining needle, it is installed in the Injector Bushing base, cylindrical, it is characterized in that: the front portion is dissectd equably vertically and is two halves, the rear portion along the front portion same tangent plane at the center the die-cut trace that cuts open that is provided with a width less than cylindrical diameter.Like this, the trace that cuts open that the slit of whole incision and part are die-cut is convenient to passing of puncture needle, and puncture needle passes Shi Buhui and takes buffings out of; When extracting puncture needle, the slit of cutting on the sealing-plug and die-cut cut open trace and can seal up pin hole immediately, sealing is reliable.
This utility model hemostatic seal plug of vein-retaining needle is provided with an annular groove in the middle of its cylindrical outer surface.The annular protrusion that is provided with in itself and the casing seat cooperates, and is used for hemostatic seal plug stably is fixed in the Injector Bushing base.
This utility model sealing-plug be provided with the slit of a whole incision and part die-cut cut open trace, against existing technologies, it is convenient to installing and fixing of puncture needle, can not take buffings out of, strengthened the sealing property of sealing-plug, extract puncture needle after, sealing-plug has been blocked the blood outflow fully.This utility model is simple and reasonable for structure, and closure is good, can prevent the blood outflow effectively, makes things convenient for operation of medical workers, avoids medical personnel are damaged.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is a structural representation of the present utility model.
1. slits among the figure, 2. annular groove 3. cuts open trace.
The specific embodiment
As seen from Figure 1, a kind of hemostatic seal plug of vein-retaining needle, it is installed in the Injector Bushing base, and is cylindrical, and its length is 2-10mm, and diameter is 1-8mm.Generally be to make of the elastomeric material of good springiness.Before sealing was used, puncture needle was axially to go up by this part.After puncture is finished, extract puncture needle, pin hole is sealed, be mainly used in and prevent leaking outside and exosmosing of liquid and blood during transfusion and the indwelling by the extruding of casing seat inwall and the elasticity of sealing-plug rubber itself.
This utility model characteristics are: the front portion of cylindrical seal plug integral body is vertically dissectd equably and is two halves, and there is slit 1 centre, whole two halves smooth surface of cutting.Same tangent plane is die-cut at the center along the front portion at the rear portion is provided with a width and cuts open trace 3 less than cylindrical diameter.Slit 1 and cut open trace 3 and be communicated with.The length that this utility model front portion is dissectd is the 1/5-3/5 of whole sealing-plug length, and the length that the front portion is dissectd is generally 0.4-6mm.The rear portion is cutd open trace 3 die-cut width and is generally 0.6-6mm.Like this, the trace 3 that cuts open that whole slit of dissecing 1 and part are die-cut is convenient to passing of puncture needle, and puncture needle passes Shi Buhui and takes buffings out of; When extracting puncture needle, slit 1 of cutting on the sealing-plug and the die-cut trace 3 that cuts open seal up pin hole immediately by the extruding of casing seat inwall and the elastic energy of sealing-plug rubber itself, and sealing is reliable.
Be provided with an annular groove 2 in the middle of this utility model cylindrical outer surface.The annular protrusion that is provided with in itself and the casing seat cooperates, and is used for hemostatic seal plug stably is fixed in the Injector Bushing base.
Claims (4)
1. hemostatic seal plug of vein-retaining needle, it is installed in the Injector Bushing base, and is cylindrical, it is characterized in that: the front portion is dissectd equably vertically and is two halves, the rear portion along the front portion same tangent plane at the center the die-cut trace that cuts open that is provided with a width less than cylindrical diameter.
2. hemostatic seal plug of vein-retaining needle according to claim 1 is characterized in that: it is 0.4-6mm that length is dissectd in the front portion.
