Abstract
The utility model provides an infusion set connecting piece for dialysis. The infusion set connecting piece comprises a blood backflow pipe, wherein a branching pipe and a rotary valve are arranged in the middle of the blood backflow pipe; the branching pipe is communicated with the blood backflow pipe; the rotary valve and the blood backflow pipe are in threaded connection; the branching pipe and the blood backflow pipe are jointlessly formed when being manufactured; a snap ring is further arranged on the blood backflow pipe; a connection pipe is arranged at the end part of the branching pipe; a filter is arranged in the middle of the branching pipe; the snap ring and the blood backflow pipe are jointlessly formed when being manufactured; and the filter, the connection pipe and the branching pipe are jointlessly formed when being manufactured. The infusion set connecting piece for dialysis has a simple structure, is used conveniently; and antipyrotic liquid medicine can be infused when dialyzed blood flows back, so that pains suffered by a patient and caused by repeated subcutaneous injection can be avoided.
Description
Technical field:
This utility model relates to technical field of medical instruments, particularly a kind of dialysis transfusion device connector.
Background technology:
Dialysis is to be diffused into the principle of water (or buffer) by micromolecule through semipermeable membrane, a kind of separating and purifying technology that micromolecule and biomacromolecule are separated.Dialysis therapy is the Therapeutic Method that the composition (solute or moisture) in the body fluid is excreted by semipermeable membrane, generally can be divided into two kinds of hemodialysis and peritoneal dialysis.Wherein, about the hemodialysis of nephropathy, be called for short hemodialysis, popular saying also is referred to as artificial kidney, washes kidney, is a kind of of blood purification technology.It utilizes the semipermeable membrane principle, by diffusion, various harmful and unnecessary metabolic wastes and too much electrolyte shift out externally in the convection cell, reach the purpose that purifies the blood, and inhales and reaches the purpose of correcting Water-Electrolyte and acid-base balance.The Therapeutic Method that composition (solute or moisture) in the body fluid is excreted by semipermeable membrane.Be usually used in situation acute or that chronic renal failure, medicine or other poisonous substances are accumulated in vivo.Dialysis commonly used has hemodialysis and peritoneal dialysis.Hemodialysis therapy: patient's blood and dialysis solution are introduced dialyser (both flow directions are opposite) simultaneously, utilize the semipermeable membrane of dialyser (artificial kidney), go out the too much toxin accumulated in the blood and too much moisture external clearly, and additional base is to correct acidosis, adjust electrolyte disturbance, substitute the excretory function of kidney.Hemodialyzer is commonly called as artificial kidney, and hollow fibre type, coil-type and plate 3 kinds are arranged.The most frequently used is the hollow fibre type, is made up of 1～1.5 ten thousand hollow fibre, and the wall of hollow fibre is a dialyzer, tool semipermeable membrane character.Blood flows in the every hollow fibre during hemodialysis, and dialysis solution flows through outside every hollow fibre, and the flow direction of blood is opposite with the mobile direction of dialysis solution, removes poisonous substance by the semipermeable membrane principle, removes moisture by ultrafiltration and infiltration.When doing hemodialysis, need be in blood circulation state for a long time, all need in patient's vein place imbedding needle, be that the patient does the misery that subcutaneous puncture brings to the patient to avoid as far as possible repeatedly.Blood behind the diafiltration also needs independent subcutaneous injection infusion anti-inflammation drugs in body simultaneously in being back to body the time sometimes, to avoid the fever situation of back patient in the blood re-injection body, at this moment, then needs intravenous injection anti-inflammation drugs separately again.In view of above-mentioned technical problem, press for occur a kind of simple in structure, easy to use, can be when dialysis blood refluxes a kind of dialysis transfusion device connector of infusion antiinflammatory medicinal liquid.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, can be when dialysis blood refluxes a kind of dialysis transfusion device connector of infusion antiinflammatory medicinal liquid.
To achieve these goals, this utility model provides a kind of dialysis transfusion device connector, comprise bleed back tube, wherein, the middle part of described bleed back tube is provided with branched pipe and rotary valve, described branched pipe is connected with described bleed back tube, is threaded between described rotary valve and the described bleed back tube, and described branched pipe and described bleed back tube are one-body molded during fabrication.
Further be provided with snap ring on the described bleed back tube, the end of described branched pipe is provided with connection tube, the middle part of described branched pipe is provided with filter, described snap ring and described bleed back tube are one-body molded during fabrication, and described filter, described connection tube and described branched pipe are one-body molded during fabrication.
Described bleed back tube, described snap ring, described branched pipe, described connection tube are nontoxic PE goods.
Described rotary valve is used to control opening or closing of branched pipe.
Advantage of the present utility model is, and is simple in structure, easy to use, can be when dialysis blood refluxes infusion antiinflammatory medicinal liquid, avoid doing the misery that subcutaneous injection brings to the patient repeatedly.Specific as follows:
One end of bleed back tube of the present utility model plugs together with the seam of patient's vein imbedding needle and is connected, and the other end plugs together with the return pipe of dialysis machine and is connected, and so promptly forms closed circuit with dialysis machine.Connection tube on the branched pipe plugs together with intravenous garter needle tubing and is connected, and rotary valve is used to control opening or closing of branched pipe.When needs were given the patient infusion anti-inflammation drugs, the rotation rotary valve made branched pipe be connected with bleed back tube.Can be for the patient import anti-inflammation drugs in the dialysis blood that refluxes, the misery of avoiding the subcutaneous skin of repeated localised puncture patient to bring.

The specific embodiment:
Below in conjunction with accompanying drawing, this utility model is described.
As shown in Figure 1, Fig. 1 is a structural representation of the present utility model.Comprise bleed back tube 1, wherein, the middle part of bleed back tube 1 is provided with branched pipe 6 and rotary valve 3, and branched pipe 6 is connected with bleed back tube 1, is threaded between rotary valve 3 and the bleed back tube 1, and branched pipe 6 and bleed back tube 1 are one-body molded during fabrication.Further be provided with snap ring 2 on the bleed back tube 1, the end of branched pipe 6 is provided with connection tube 4, the middle part of branched pipe 6 is provided with filter 5, and snap ring 2 is one-body molded during fabrication with bleed back tube 1, and filter 5, connection tube 4 and branched pipe 6 are one-body molded during fabrication.Bleed back tube 1, snap ring 2, branched pipe 6, connection tube 4 are nontoxic PE goods.Rotary valve 3 is used to control opening or closing of branched pipe 6.
One end of bleed back tube of the present utility model plugs together with the seam of patient's vein imbedding needle and is connected, and the other end plugs together with the return pipe of dialysis machine and is connected, and so promptly forms closed circuit with dialysis machine.Connection tube on the branched pipe plugs together with intravenous garter needle tubing and is connected, and rotary valve is used to control opening or closing of branched pipe.When needs were given the patient infusion anti-inflammation drugs, the rotation rotary valve made branched pipe be connected with bleed back tube.Can be for the patient import anti-inflammation drugs in the dialysis blood that refluxes, the misery of avoiding the subcutaneous skin of repeated localised puncture patient to bring.
