The peripheral vein transfusion catheter can be directly used as an indwelling catheter at the basilic vein, the cephalic vein, the median cubital vein and the like, can carry out puncture under direct vision, is high in success rate, is small in trauma, enables hemostasis to be easy, reduces the infection probability, enables a patient to feel safe, and is accepted easily.
Description
Technical field
The present invention relates to medical instruments field, be specifically related to a kind of Peripheral vein infusion conduit.
Background technology
Along with the development of venous transfusion technology, venous duct technology because it is simple to operate, safety, puncture success rate is high, little to patient's wound; few intercurrent disease, does not affect patient's normal activity, can keep somewhere the long period in body; the advantages such as patient is acceptant, are used widely clinically.At present common venous duct have central venous catheter (CVC), through Peripherally inserted central catheter (PICC), hemodialysis catheter etc.No matter be that CVC or PICC need in conduit centering venous duct, put that pipe complicated operation, complication are many and cost is high.If adopt remaining needle mode to infuse for the patient who needs long-term infusion, because being subject to the restriction of Integrated catheter and indwelling time to be difficult to satisfy the demands.Adopt peripheral vein catheterization, through a venipuncture, just can be retained in intravenous for a long time to patient infusion, also have do not leak blood, avoid infection, the feature such as easy to operate, both solved and carried out the misery that venipuncture could be infused every day, eliminated needle tubing and often punctured at intravenous the harm that vein causes local hematoma, solved again expensive, the excessive risk defect of CVC and PICC, for venous transfusion provides a kind of safer, effectively selection.But be not specifically applied in the market the product of peripheral vein catheterization infusion treatment, thereby restricted the selection of Peripheral vein infusion treatment.
Summary of the invention
The object of the invention is to solve the problem of the Peripheral vein infusion conduit that is not specifically applied to peripheral vein catheterization infusion treatment in prior art, a kind of peripheral venous catheter that is applicable to basilic vein, cephalic vein, Cubital vein place tube is provided.
The object of the invention is to be achieved through the following technical solutions:
Venous infusion catheter, comprise main body tube, infusion medicinal liquid joint and connecting device, main body tube is connected by connecting device with infusion medicinal liquid joint, described connecting device comprises in conjunction with handle and extension pipe, in conjunction with handle front end, be connected with main body tube, rear end is connected with infusion medicinal liquid joint through extension pipe, on described extension pipe, is provided with tongs.
Further, the built-in seal wire of described venous infusion catheter.
Further, described venous infusion catheter is provided with anti-reflux valve, the T-shaped structure of described anti-reflux valve, and anti-reflux valve one end access node closes handle, a termination extension pipe, one end is connected with seal wire joint.
More preferably, the combination handle of Peripheral vein infusion conduit and main body tube connecting portion adopt reducing to process, and in conjunction with the caliber of handle and main body tube connecting portion, along main body tube direction, diminish gradually, prevent from occurring when main body tube from inserting human body fracture of root.
More preferably, Peripheral vein infusion catheter main body catheter tip is the round and smooth structure that has certain taper, can reduce the damage to blood vessel in use procedure.
More preferably, Peripheral vein infusion conduits join handle is made by soft silica gel, reduces the stimulation to skin.
More preferably, Peripheral vein infusion conduit, by adopting the not saturating X ray silica gel of medical grade to make, reduces phlebitis and other complication probability of happening, reduces the stimulation to blood vessel, is difficult for occurring thrombosis.
More preferably, infusion medicinal liquid joint adopts female Luer.
The invention has the beneficial effects as follows, Peripheral vein infusion conduit of the present invention can be directly used in basilic vein, cephalic vein, Cubital vein place tube, can under direct-view, puncture, and success rate is high; Wound is little, and hemostasis easily; Infecting probability can lack; Patient feels safe, acceptant.The clinical rescue that can be used for patient, use the treatments such as dehydrant, intravenous nutrition and long-term infusion.Peripheral vein infusion conduit has the following advantages: (1), for subclavian vein puncture and internal jugular vein puncture (central venous catheter), has complication still less, simple to operate and risk is little; (2) with respect to remaining needle, have longer indwelling time and service time, and minimizing is oozed out; (3) with respect to other venous ductes, more save medical expense; (4) reduce the risk infecting; (5) compare with chemotherapy pump, do not need operation to place; (6) puncture when patient does not need to infuse at every turn, reduces puncture risk, reduces painful, more comfortable; (7) nursing is simple, reduces medical personnel's labor intensity.

The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with the drawings and the specific embodiments in detail the present invention is described in detail.But should be appreciated that the specific embodiment described herein is only for explaining the present invention, and for limiting the present invention.
One embodiment of the present invention, as shown in Figure 1, venous infusion catheter, comprise main body tube 1, infusion medicinal liquid joint 5 and connecting device, main body tube 1 is connected by connecting device with infusion medicinal liquid joint 5, and described connecting device comprises in conjunction with handle 2 and extension pipe 3, in conjunction with handle 2 front ends, is connected with main body tube 1, rear end is connected 5 through extension pipe 2 with infusion medicinal liquid joint, on described extension pipe 2, is provided with tongs 4.Peripheral vein infusion conduit is in order to meet different clinical demands, and its specification is divided into 16GA, 18GA, 20GA, 22GA, and main catheter body length is 13 ㎝, 16 ㎝, 20 ㎝, 30 ㎝ etc.
The preferred embodiment of the present invention, as shown in Figure 2, the built-in seal wire 7 of venous infusion catheter, is provided with anti-reflux valve 8, and anti-reflux valve 8 is T-shaped structure, and anti-reflux valve 8 one end access nodes close handle 2, one termination extension pipes 3, and one end is connected with seal wire joint 6.The built-in seal wire of Peripheral vein infusion conduit, easy to operate, T-shaped anti-reflux valve, while extracting seal wire out after putting pipe, can effectively stop blood backflow.Micro-movement of conduit when T-shaped anti-reflux valve also can reduce operation.Further improve the performance of venous infusion catheter.
As shown in Figure 3, the combination handle 2 of Peripheral vein infusion conduit and main body tube 1 connecting portion adopts reducing to process, and in conjunction with the caliber of handle and main body tube connecting portion, along main body tube direction, diminishes gradually, prevents from occurring when main body tube from inserting human body fracture of root.
As shown in Figure 4, Peripheral vein infusion catheter main body catheter tip is the round and smooth structure that has certain taper, can reduce the damage to blood vessel in use procedure.
Its clinical practice of Peripheral vein infusion conduit of the present invention, can be with reference to Fig. 5, and it is depicted as basilic vein and puts pipe, and clinical basilic vein, median cubital vein or the cephalic vein conventionally selected is as site of puncture.During use, need to measure intubation length, select suitable conduit.According to routine operation, Peripheral vein infusion conduit B is sent into vein, catheter tip arrives precalculated position A, checks the suitable rear A/C of catheter position, and extension pipe is connected on infusion pipeline and is infused.While not using, after being full of with suitable heparin-saline, with calparine cap, seal.
