Abstract
The utility model provides a sealing tube core of an indwelling pin, which relates to a field of medical appliance. The structure of the utility model is characterized in that a conical core seat (2) is provided with a tube core (1), and a screw-cap (3) is equipped outside of the core seat (2), the interior of the core seat is provided with screw threads which externally fit with the tube seat of the indwelling pin and connectes the sealing tube core and the tube seat of the indwelling pin. The utility model has the advantages of reasonable design, simple structure, economic manufacture, convenient employment, safety and reliability, and has no side effects for the human body.
Description
Affiliated technical field:
This utility model relates to the medical apparatus field, relates to a kind of venous detaining needle tube sealing core particularly.
Background technology
In the prior art, venous detaining needle adopts the calparine cap tube sealing usually clinically, and be used heparin sodium liquid, in case hemostasis liquid solidifies plugging, though convenient feasible advantage is arranged, but have following shortcoming simultaneously: the one, the heparin liquid that envelope adopts during indwelling needle catheter, enter into blood after, the human liver is had harm; The 2nd, during with calparine cap envelope indwelling needle catheter, because the pressure of venous blood, blood enters in the conduit and forms face with heparin sodium liquid, enter this part blood in the conduit, be easy to solidify, enter when infusing once more in the body, form thrombosis, human body is worked the mischief, stop up conduit when serious, remaining needle can not reuse, the indwelling of have to puncturing once more, both cause patient's misery, be unfavorable for clinical care again.Along with the development of society, progress of science and technology, people wish appearing on the market of a kind of novel remaining needle tube sealing core, with treatment and the nursing demand that satisfies clinical remaining needle, improve people's health level.
Summary of the invention
The purpose of this utility model provides a kind of remaining needle tube sealing core, and it is the shutoff remaining needle rapidly, can overcome the problems of present clinical existence again effectively.
The purpose of this utility model is achieved through the following technical solutions, the main feature of its structure is to be provided with tube core 1 on conical core print seat 2, outside tube core 2, be provided with screw-cap 3, be provided with the screw thread that matches with indwelling needle catheter in it outward, be connected in tube sealing core and indwelling needle catheter seat.
The diameter of its construction features tube core 1 matches with the inlying catheter internal diameter, and its length is identical with indwelling needle catheter.
Good effect of the present utility model:
One, reasonable in design, simple in structure, make economical, easy to use;
Two, be used for clinical use with physical method, thoroughly overcome of the harm of heparin sodium liquid the human liver, without any side effects;
Three, overcome blood and in conduit, stopped, hemopexis can not occur, avoided causing the harm of thrombosis to patient;
Four, in use do not have conduit and stop up, guarantee that remaining needle stays the time of planting long, safe and reliable.
Description of drawings
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is the structural front view according to the remaining needle tube sealing core that the utility model proposes.
Fig. 2 is the structure left view according to the remaining needle tube sealing core that the utility model proposes.
1-tube core among the figure, 2-core print seat, 3-screw-cap.
The specific embodiment
As shown in Figure 1 and Figure 2, this utility model is formed by connecting by tube sealing core 1, core print seat 2 and screw-cap 3, and construction features is to be provided with tube core 1 on conical core print seat 2, is provided with screw-cap 3 outside core print seat 2.Be provided with in it and the outer screw thread that matches of indwelling needle catheter (not drawing among the figure), connect tube sealing core and indwelling needle catheter seat.The diameter of tube core 1 matches with indwelling needle catheter internal diameter (not drawing among the figure), and its length is identical with indwelling needle catheter, and its material is identical with indwelling needle catheter, and this product can disposablely use, to prevent cross infection.Its work process is as follows, during use earlier with retained needle puncture in human body, transfusion then, behind the liquid of being totally lost, with remaining needle tube sealing core by the remaining needle base insert in the conduit (not drawing among the figure) interior after, be inserted in to screw on the indwelling needle catheter seat with screw-cap 3 and get final product.It is reasonable in design, and is simple in structure, easy to operate.
Claims (2)
1, a kind of remaining needle tube sealing core that contains tube core, core print seat, screw-cap, it is characterized in that on conical core print seat (2), being provided with tube core (1), outside core print seat (2), be provided with screw-cap (3), be provided with the screw thread that matches with the indwelling needle catheter seat in it outward, be connected in tube sealing core and indwelling needle catheter seat.
2, according to claim 1, described remaining needle tube sealing core is characterized in that the diameter of tube core (1) matches with the indwelling needle catheter internal diameter, and its length is identical with indwelling needle catheter.
