Description
Technical field
The present invention relates to medicine equipment, and in particular to a kind of dialysis catheter for nephrology department fixing device.
Background technology
Kidneys filter blood, remove discarded material.If renal failure, waste is accumulated in vivo, eventually poisons
Human body.Rend dialysis is also known as artificial kidney, and also someone is blood dialysis (abbreviation hemodialysis) or washes kidney.Haemodialysis English is
Hemodialysis, Hemo refer to blood, and dialysis comes from Greek, means and discharge Cucumber, and the English meaning is
Dialysis.It is one kind of blood purification technology.It is hemodialysis that majority in 500,000 patients that dialysis sustains life is relied in the whole world.Blood
Thoroughly to mitigating patient symptom, extension life cycle has the certain significance.
Dialysis refers to the process of solute from the side of pellicle through film to opposite side.Any naturally (such as peritonaeum) or people
The pellicle made, as long as the film contains the aperture for passing through a certain size solute, then those solute cans pass through disperse
The opposite side of film is moved to from the side of film with convection current.Hemodialysis is the principle using pellicle, by patient blood and dialyzate
Dialyzer is introduced simultaneously, is in opposite direction activity in dialysis membrane both sides, by solubility gradient, osmotic gradient and the water of pellicle both sides
Gradient is pressed, passes through disperse, convection current, adsorption removal toxin；Moisture unnecessary in vivo is removed by ultrafiltration and infiltration；Supplementing simultaneously needs
The material wanted, correct electrolyte, disturbance of acid-base balance." poisonous substance " in human body includes metabolite, medicine, exogenous poisonous substance,
As long as its atomic weight or molecular size range are appropriate, it becomes possible to are cleared out of by dialysis external.Its general principle is disperse and convection current.
Disperse is exactly pellicle both sides liquid each contained solute concentration gradient and the different osmotic concentrations that it is formed, and solute is from concentration
Moved by pellicle to the low side of concentration high side.Convection current is also referred to as ultrafiltration, refers to solute and solvent because of dialysis membrane both sides
Hydrostatic pressing and osmotic pressure gradient be different and the process of transmembrane transport.
Traditional Nephrology dept.'s dialysis operation is due to no fixing device, and dialysis tubing is disorderly and unsystematic, therefore is grasped in operation
Usually from hospitalized patients bring puzzlement in work.
The content of the invention

Diameter parallel, the first neck cross section are major arc；Fixedly connected part is arranged at intervals, strengthens the fixation to dialysis tubing,
There is more preferable applicability simultaneously, metal stereotypes hoses facilitate fixedly connected part to place for random adjustment angle, the first neck
Cross section is arranged to the clamping ability of major arc increase neck.
Specifically, being provided with a ring groove around the fixedly connected part, the annular groove cross section is minor arc；Facilitate doctor couple
Fixedly connected part take and the excision to dialysis tubing.
Specifically, being additionally provided with the second neck in the fixedly connected part between the first neck, the second neck both sides are
Clamping plane；The clamping plane is used for fixedly connected part card on a metal plate.
Specifically, the bottom of second neck is provided with spherical magnet, the clamping plane, which is provided with, prevents spherical magnet
The projection to drop, the adsorption capacity between spherical magnet increase and metallic plate.
Specifically, the first neck top is provided with rounding；Facilitate scratch dialysis tubing, increase the success rate of clamping.
Specifically, the second neck top is provided with chamfering, metallic plate is conveniently blocked.
Specifically, first pocket numbers are more than 2, depending on surgery situation.
Effective effect
The present invention provides a kind of dialysis catheter for nephrology department fixing device, by fixedly connected part and metal stereotypes hoses come pair
Dialysis tubing is fixed and adjusted, and prevents that dialysis tubing tampers in dialysis operation, facilitates doctor to check, improves the accurate of operation technique
