Abstract
A jugular puncture central vein indwelling catheter joint for plasma replacement of patients with severe hepatitis. Mainly solves the problem that the prior severe hepatitis patient has no proper catheter joint when plasma replacement is carried out and the central vein is reserved by the cervical puncture. The method is characterized in that: the outside of the leading-out conduit (2) is connected with a circular main joint, and the main joint is composed of a plurality of joint monomers (6) sealed in the sealing paper (3) and a communicating chassis (5); wherein the leading-out conduit (2) is communicated with the communicating chassis (5), and the plurality of joint monomers (6) are also communicated with the communicating chassis (5); the joint single body (6) is provided with an external thread matched with the connecting thread on the heparin cap and is stuck with tin sealing paper (4). The structure of the indwelling catheter joint is very simple, and after the sealing of one single joint fails, another new single joint can be started until all the single joints are used up, so that the patient is prevented from suffering from the re-indwelling catheter joint.
Description
Technical field
This utility model relates to a kind of medical auxiliary implement that is used for liver disease, specifically, relates to a kind of inlying catheter joint of using when the hepatitis gravis patient carries out plasmapheresis of being used for.
Background technology
The therapeutic plasma exchange that what is called is used for the hepatitis gravis patient is outside the blood lead body with hepatitis; Process membrane type blood plasma separation method or other separation method are separated patient's blood plasma and are discarded from whole blood; Replenish the displacement liquids such as FFP or human albumin of equivalent then; So just, can remove intravital various metabolism toxin of patient and virulence factor, thereby reach therapeutic purposes.Before carrying out plasmapheresis, need set up the artery and vein passage earlier, arterial end blood is introduced plasma separator, behind isolation of purified, blood and the displacement liquid that will purify are fed back in the body by vein end again.In carrying out this therapeutic process, several kinds of conduits are inserted method below adopting mostly: one of which is that arteriovenous keeps intubation, generally selects dorsal artery of foot and internal malleolus great saphenous vein intubate for use; It two is the outer fistula method of artery and vein, promptly selects the cephalic vein of radial artery and companion's row thereof for use, inserts the entad end of artery and vein respectively with two silicone rubber tubes, and row skin connects the organizator external shunt outward; It three is the subclavian vein tremie method, is about to double channel catheter and inserts subclavian vein, and blood, is fed back in the body by interior pipe behind the plasma separator of flowing through through the sucking-off of trocar sheath side opening again.The problem that exists in the prior art is, no matter which kind of method of employing all need be inserted the arteriovenous end with conduit and keep somewhere when carrying out plasmapheresis; When especially carrying out puncturing in the neck central venous cattaeter; Operation is complicated, if repeatedly keep somewhere, will bring huge misery to the patient.But existing inlying catheter joint tends to again cause seal failure because repeatedly screw in calparine cap, makes and has in a therapeutic process, repeatedly change the catheter retaining joint, and increased patient institute suffer, what influence was performed the operation normally carries out.
Summary of the invention
In order to solve the problem that prior art that background technology proposes exists; This utility model provides a kind of severe hepatopath plasmapheresis with puncture central venous cattaeter joint in the neck; This kind inlying catheter joint design is very simple, can after a monomer joint sealing lost efficacy, launch another new monomer joint; Use up until whole monomer joints, thereby make the patient avoid the hardship of inlying catheter joint again.
The technical scheme of this utility model is: this kind severe hepatopath plasmapheresis is with puncture central venous cattaeter joint in the neck; Comprise the extraction catheter that has built-in conduit connector; The total joint that outside said extraction catheter, connects a circle, said total joint is made up of with the connection chassis some joint monomers that are closed in the sealed paper; Wherein, extraction catheter is connected with the connection chassis, and some joint monomers also are connected with the connection chassis; Have on the joint monomer with calparine cap on the external screw thread that matches of connecting thread, and be pasted with stannum envelope paper.
In addition, for ease of opening each monomer joint, the edge of the monomeric sealed paper of corresponding each joint is pressed with peelable dotted line impression.
The utlity model has following beneficial effect: this kind severe hepatopath plasmapheresis is with puncture central venous cattaeter joint in the neck; On a total joint, be equipped with some monomer joints; Monomer joint sealing lost efficacy and can not be again with after calparine cap is connected, launch another new monomer joint and through sealing with wax used joint, like this; Use up until whole new monomer joints, just can once keep somewhere the operation of joint again.Through using this kind catheter adapter, can finish a plasmapheresis basically with the treatment course of treatment of puncturing in the neck, thereby make the patient avoid the hardship of inlying catheter joint again.
Description of drawings:
Fig. 1 is the structural representation after this utility model is torn the corresponding sealed paper of a joint monomer.
Fig. 2 is that this utility model is torn the corresponding sealed paper of a joint monomer and shown the sketch map that is communicated with chassis structure.
Fig. 3 is in the structural representation of unused state for this utility model.
The built-in conduit connector of 1-among the figure, the 2-extraction catheter, the 3-sealed paper, 4-stannum envelope paper, 5-is communicated with the chassis, 6-joint monomer.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is described further:
As shown in Figure 1; This kind of severe hepatopath plasmapheresis is with puncture central venous cattaeter joint in the neck; Comprise the extraction catheter 2 that has built-in conduit connector 1; The total joint that outside said extraction catheter 2, connects a circle, said total joint is made up of with connection chassis 5 some joint monomers 6 that are closed in the sealed paper 3.Wherein, extraction catheter 2 is connected with connection chassis 5, and some joint monomers 6 also are connected with connection chassis 5; Have on the joint monomer 6 with calparine cap on the external screw thread that matches of connecting thread, and be pasted with stannum envelope paper 4.
In addition, for ease of opening each monomer joint, the edge of the sealed paper 3 of corresponding each joint monomer 6 is pressed with peelable dotted line impression.
During use, at first conduit connector 1 is connected with pre-buried conduit in artery and vein, afterwards, just can directly uses after tearing the sealed paper of corresponding certain joint monomer 6.Monomer joint sealing lost efficacy and can not be again with after calparine cap is connected, launch another new monomer joint and, like this, use up until whole new monomer joints through sealing with wax used joint, just can once keep somewhere the operation of joint again.
Claims (2)
1. a severe hepatopath plasmapheresis comprises the extraction catheter (2) that has built-in conduit connector (1) with puncture central venous cattaeter joint in the neck, it is characterized in that:
The outer total joint that connects a circle of said extraction catheter (2), said total joint is closed in the joint monomer (6) in the sealed paper (3) and is communicated with chassis (5) formation by some; Wherein, extraction catheter (2) is connected with connection chassis (5), and some joint monomers (6) also are connected with connection chassis (5); Have on the joint monomer (6) with calparine cap on the external screw thread that matches of connecting thread, and be pasted with stannum envelope paper (4).
