Description
Technical field
The present invention relates to medical apparatus and instruments, be specifically related to a kind of dialysis catheter for nephrology department fixture.
Background technology
Kidneys filter blood, removes discarded material.If renal failure, refuse is accumulated in vivo, finally can poison human body.Rend dialysis is also known as artificial kidney, and also someone is blood dialysis (abbreviation hemodialysis) or washes kidney.Hemodialysis English is that Hemodialysis, Hemo refer to blood, and dialysis, from Greek, is meant to discharge Cucumber, and the English meaning is dialysis.It is the one of blood purification technology.Relying on majority in 500,000 patients dialysing and sustain life in the whole world is hemodialysis.Hemodialysis, to alleviating patients symptomatic, extends life cycle and all has the certain significance.
Dialysis refer to solute from the side of semipermeable membrane through film to the process of opposite side.Any naturally (as peritoneum) or artificial semipermeable membrane, as long as this film contains the aperture making a certain size solute pass through, so those solutes just can move to the opposite side of film by disperse and convection current from the side of film.Hemodialysis is the principle utilizing semipermeable membrane, and patient blood and dialysis solution are introduced dialyser simultaneously, in dialyzer both sides in movable in the other direction, by means of the solubility gradient of semipermeable membrane both sides, osmotic gradient and hydraulic pressure gradient, by disperse, convection current, adsorption removal toxin; By moisture unnecessary in ultrafiltration and infiltration purged body; Supplement the material needed simultaneously, correct electrolyte, acid base imbalance." poisonous substance " in human body comprises metabolite, medicine, exogenous poisonous substance, as long as its atomic weight or molecular size range are suitably, just can be cleared out of external by dialysis.Its ultimate principle is disperse and convection current.Disperse is exactly semipermeable membrane both sides liquid contained solute concentration gradient and its different osmotic concentration of forming separately, and solute is moved to the side that concentration is low from the side that concentration is high by semipermeable membrane.Convection current also claims ultrafiltration, refers to that solute and solvent are because of the hydrostatic pressing of dialyzer both sides and the process of transmembrane transport different with osmotic pressure gradient.
Traditional Urology Department dialysis operation is not owing to having fixture, and Dialysis tubing is disorderly and unsystematic, therefore in operation technique usually for hospitalized patients brings puzzlement.
Summary of the invention
The invention provides a kind of dialysis catheter for nephrology department fixture, solve existing Dialysis tubing disorderly and unsystematic, the problem of inconvenient operation technique, concrete technical scheme is as follows:
A kind of dialysis catheter for nephrology department fixture, comprise metal sizing flexible pipe and fixed connecting piece, described fixed connecting piece is provided with the through hole through metal sizing flexible pipe, described metal sizing flexible pipe is interval with fixed connecting piece, described fixed connecting piece is cylinder, and the first draw-in groove be around provided with for fixing Dialysis tubing, the axis being parallel of described first draw-in groove and fixed connecting piece, described first draw-in groove cross section is major arc; Interval arranges fixed connecting piece, strengthens the fixation to Dialysis tubing, has the better suitability simultaneously, and metal sizing flexible pipe is used for arbitrarily adjustment angle and facilitates fixed connecting piece to place, and the first draw-in groove cross section is arranged to the clamping ability that major arc increases draw-in groove.
Concrete, be provided with a ring groove around described fixed connecting piece, described annular groove cross section is minor arc; Facilitate doctor's taking and excision to Dialysis tubing to fixed connecting piece.
Concrete, described fixed connecting piece is also provided with the second draw-in groove between the first draw-in groove, and described second draw-in groove both sides are clamping plane; This clamping plane is used for by fixed connecting piece card on a metal plate.
