Description

Plug assembly and the remaining needle without glue connection is isolated
Technical field
The present invention relates to a kind of infusion isolation plug assembly and with the isolation plug assembly without glue connection indwelling Needle belongs to medical instruments field.
Background technique
Substitute of the venous detaining needle as scalp acupuncture, has that easy to operate, soft, indwelling time is long, no in vein The advantages that easily wearing out blood vessel, alleviates the workload of pain and nursing staff that patient punctures repeatedly.
Remaining needle in the prior art, as shown in Figure 1, connected using glue at A, B, C tri-.Although medical Glue, but polymer substance is existing using water as carrier, there are following harm in real use:
1, it there are non-uniform situation when putting glue, be easy to cause and is bonded loosely, cause blood or transfusion liquid to leak, cause Malpractice;
2, in use, glue bonding site is easy to be influenced by environment temperature, humidity and chemical mediator etc.;
3, when dispensing operates, glue causes stimulation to injure skin, the eyes of operator, when serious, causes malpractice;
4, glue is chemical industry article, and chemical component is harmful to the human body after being precipitated;
5, there are heavy metals exceeding standards for the medical glue in part, and in use, heavy metal ion releasing has length to human health Remote harm.
In addition, that is, at batching pig, by the side opening dispensing on threeway needle stand, making to fill in the looping pit of batching pig at for B Full glue, to realize the gluing between batching pig and threeway needle stand.And the batching pig is made of the harder rubber of material, Process complexity is cumbersome, at high cost, and because of central imperforate, the inaccurate situation of positioning is easy to appear in contact pin, influences to wear Transfusion operation is pierced, the discomfort of patient is also easily caused.
CN2015103650398 discloses a kind of batching pig and the venous detaining needle with the batching pig, which is One elastomer for being punctured or being pulled away by needle tubing forms in batching pig after needle tubing punctures intervention batching pig and punctures access, puncture logical Road coats the periphery of needle tubing and has press force to the tube wall of needle tubing, and puncturing has gap between access and needle tubing tube wall.It is this After needle tubing exits, puncturing hole can disappear the batching pig of structure at once, though it is effectively prevent blood backflow, but its next time punctures When, it is inaccurate still to there is a situation where positioning, and because designing channel on batching pig, and cause sealing effect bad, in addition, this rubber Rubber plug is also that glue is connect with catheter block, and especially under high pressure, rubber stopper is easy to disengage with catheter block and cause to reveal.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of design of structure is more reasonable and anti- Plug assembly and the remaining needle without glue connection with the isolation plug assembly is isolated in the good infusion of thrombus effect.
To achieve the above object, the technical solution adopted by the present invention first is that: isolation plug assembly, including batching pig are special Sign is that the batching pig is made using silica gel or silicon rubber or polyisoprene material, and the batching pig is being worn Pricker extract after with middle part outwardly against or both ends outwardly against elasticity;It is machined at batching pig center and is mutually fitted with puncture needle The central through hole that should cooperate;It is equipped with baffle in one end of batching pig, the center of baffle is provided with coaxial with batching pig central through hole Pin hole.
The technical solution adopted by the present invention second is that: the remaining needle of no glue connection, including threeway needle stand, be set to threeway The indwelling hose of needle stand front end and puncture needle, setting and threeway needle stand into indwelling hose are penetrated from threeway needle stand rear end Interior isolation plug assembly, transfusion catheter, Y-type three way type attachment base, which is characterized in that threeway needle stand be isolated between plug assembly, three It is no glue connection between cleansing pin seat and transfusion catheter and between transfusion catheter and Y-type three way type attachment base.
Preferably, threeway needle stand be isolated between plug assembly without glue connection type are as follows: the rear end of threeway needle stand at Type has the buckle for baffle in clamping isolation plug assembly, is isolated between the baffle of plug assembly and threeway needle stand using interference card Button connection.
Preferably, the top surface being bonded on the threeway needle stand with batching pig front end is plane convex surface or concave curved surface Or convex inclined plane or the face that concaves.The design of convex inclined plane and the face that concaves, it is intended that because baffle and threeway needle stand are connected using interference buckle The mode connect, from mounting distance, the deformation of the adjustable batching pig of the design of convex inclined plane and the face that concaves, to reach sealing Effect.
Preferably, between the threeway needle stand and transfusion catheter without glue connection type are as follows: transfusion catheter and three cleansing pins It snaps through by the way of being full of pressing, riveting and connects using riveted, inclined-plane pressing, double card between medical fluid input port on seat.
Preferably, between transfusion catheter and Y-type three way type attachment base without glue connection type are as follows: conveying Y-type three way type connection It snaps through by the way of being full of pressing, riveting and connects using riveted, inclined-plane pressing, double card between seat and transfusion catheter.
The batching pig of isolation plug assembly of the invention, silica gel or silicon rubber therein or the production of polyisoprene material Outer diameter is less than threeway needle stand diameter of bore, and colloid can be with Free Transform to achieve the effect that sealing.
Compared with prior art, the beneficial effect that the present invention has is:
1, it by special isolation plug assembly, need to can only be produced using bench, injection molding, manufacturing procedure is simple, instead of falling original The vulcanization compression molding come, greatly reduces cost;And because of the setting of central through hole, positioning, drop are easy in pin puncture Low operation difficulty, the situation for also avoiding puncturing repeatedly and influencing patient's discomfort occur;
2, isolation plug assembly of the invention, the connection type buckled between baffle therein and threeway needle stand using interference fit, High pressure can be born during infusion by making plug assembly entirely is isolated, and have high voltage bearing effect;
3, isolation plug assembly of the invention, wherein isolation plug assembly can release silicon when isolation plug assembly and threeway needle stand assemble The use of oil or lubricant, it is convenient for assembly;
4, by the buckle of baffle and threeway needle stand rear end, the connection between batching pig and threeway needle stand is realized, is effectively replaced It for glue connection, avoids generating a series of side effects because glue connects, and because batching pig has after puncture needle extraction Middle part outwardly against or both ends outwardly against elasticity, therefore batching pig can be always maintained at sealing state, also high pressure resistant, effectively prevent Blood and infusion reflux;
5, between the medical fluid input port on transfusion catheter and threeway needle stand, and conveying Y-type three way type attachment base and transfusion catheter it Between using riveted, inclined-plane press etc. by the way of connect, effectively instead of glue connect, avoid because glue connection due to generates accordingly Harm, reduces the pain of patient.
