Abstract
The utility model discloses a one-piece peripherally inserted central catheter, comprising a catheter, a catheter connector, a silicon tube, a connection three-way valve, a heparin cap, a lining wire, a lining wire seat, a luer cap, a luer connection piece, a hose and a stop valve, wherein one end of the catheter is connected with one end of the catheter connector; another end of the catheter connector is connected with one end of the silicon tube; another end of the silicon tube is connected with one end of the connection three-way valve, a second end of the connection three-way valve is connected with the heparin cap, the lining wire seat is connected with the heparin cap by the lining wire; a third end of the connection three-way valve is connected with the luer connection piece by the hose, the luer connection piece is connected with the luer cap; the stop valve is arranged on the hose. Because the one-piece peripherally inserted central catheter is used and the catheter is assembled in one piece with the other fittings in advance, the catheter insertion operation is simpler and easily operated, the time of the catheter insertion operation is shortened and the difficulty of the catheter insertion operation is reduced.
Description
Technical field
This utility model relates to a kind of venous duct, is integral type periphery central venous catheter specifically.
Background technology
Chemotherapy is the important means of Internal Medicine-Oncology treatment malignant tumor, and clinical route of administration commonly used is shallow venipuncture administration repeatedly.Because chemotherapeutics will cause blood vessel injury inevitably to the stimulation of blood vessel, also can make chemotherapeutics extravasation like misoperation, cause local tissue necrosis, even influence carrying out smoothly of chemotherapy.Along with the development of medical skill, the intravenously administrable method of tumour patient chemotherapeutics becomes various and brings in constant renewal in.
Periphery is inserted central venous catheter (penpherally inserted central catheter; PICC) since German doctor Forssmaon in 1992 uses first; Because of its convenient, effective and safe characteristics are widely used, compare PICC with traditional deep vein puncture and put pipe and have the characteristics that wound is little, easy and simple to handle, indwelling time is long and complication is few and be applied to clinical more and more widely.When carrying out the operation of PICC tube placing operation, by peripheral vein (median cubital vein, basilic vein, cephalic vein) puncture, its tip is positioned at superior vena cava or subclavian vein.Can for the patient provide in, secular venous transfusion treatment (7 days-1 year), or be used to the situation that needs the venoclysis hypertonicity, the zest medicine is arranged.It has the less patient suffering of alleviating, and reduces the effect that the nurse job amount improves therapeutic effect.Especially long-term fasting being needed the infusion of nutritional support, chemotherapeutics, infusion is a life pipe to the big medicine of blood zest, cancer of late stage, peripheral blood vessel puncture difficulty etc., is that the doctors and nurses rescues the successful key of critical patient.
At present, many hospitals have carried out the PICC tube indwelling technology, and have obtained clinical manipulation personnel and patient's extensive recognition and acceptance.Mostly the general clinically PICC product that uses is split-type design, complicated operation, and accessory is prone to lose, and increased the additional effort of clinical worker.
The utility model content
Goal of the invention: the purpose of this utility model is to overcome the deficiency of prior art, and a kind of integral type periphery central venous catheter easy to use is provided.
Technical scheme: to achieve these goals; This utility model provides integral type periphery central venous catheter, and it comprises: conduit, catheter extension, silica gel tube, connection three-way valve, calparine cap, guiding wire, filament guiding seat, Rule medicated cap, Rule connector, flexible pipe and vessel clamp.
The annexation of above-mentioned parts is following: said conduit one end is connected with catheter extension one end; The catheter extension other end is connected with an end of silica gel tube; The other end of silica gel tube connects with an end that is connected three-way valve; Said connection three-way valve has three ports, and this second end that connects three-way valve is connected with calparine cap, and filament guiding seat is connected with calparine cap through guiding wire; The 3rd end that connects three-way valve is connected with Rule connector through flexible pipe, and Rule connector connects Rule medicated cap; Said flexible pipe is provided with flow-stop valve.
Conduit described in this utility model is single chamber or two-chamber.Said tube material is silica gel or polyureas ammoniacum.The three-dimensional valve is positioned at the side of conduit or the top of conduit plug, and length is 4-7mm.
The function of parts is following in this utility model:
1) conduit described in this utility model, the total length autoradiography can cut catheter length according to individual instances;
2) conduit is connected with silica gel tube through catheter extension in advance in this utility model;
3) connecting three-way valve one termination described in this utility model has calparine cap, and guiding wire is connected with connection tube with conduit via calparine cap, and seal wire mainly plays guide function when putting pipe, and after conduit was inserted superior vena cava, guiding wire was promptly pulled out by filament guiding seat.
4) positive pressure infuser and negative pressure blood drawing are mainly carried out through the calparine cap puncture in this utility model;
5) said Rule medicated cap through Rule connector and flexible pipe be connected the three-way valve connection, the normal saline washing pipe carries out through Rule medicated cap;
6) flow-stop valve be furnished with of said flexible pipe, said flow-stop valve is in open mode when carrying out the normal saline washing pipe, otherwise, be in closed condition.
Beneficial effect: the described integral type periphery of this utility model central venous catheter compared with prior art has following advantage:
Because the integral type assembling in advance of the described integral type periphery of this utility model central venous catheter, its conduit and other pipe fittings makes tube placing operation simpler, easy to operate, has shortened the time of tube placing operation, has lowered the difficulty of tube placing operation.
