Description
Technical field
The invention belongs to field of medical article technology more particularly to a kind of animal peritoneal dialysis catheters.
Background technology
At present, the prior art commonly used in the trade is such：
In recent years chronic kidney disease incidence inside and outside the whole nation in ascendant trend year by year, chronic kidney disease in China's Adult Groups
Incidence is 10.8% (about 1.2 hundred million), and secondary nephrotic is with hypertension, diabetes, gout, systemic loupus erythematosus etc.
The raising of incidence, China's chronic kidney disease incidence and the death rate are in increase year by year.Regardless of it is protopathy or secondary kidney
Disease, renal failure are the final final results of chronic kidney disease.After patient enters chronic renal failure, dialysis and kidney transplant are patients
The unique channel of extending life and quality of making the life better, but in view of the limitation in organ transplant source at present so that kidney transplant
It can not popularize on a large scale.So dialysis is just into the unique selection of ordinary people.Dialysis has haemodialysis and peritoneal dialysis, blood
Liquid dialysis is stringent and very big for the dependence of medical institutions and medical worker to the physical qualification situation demand of patient, it is necessary to
To specific medical institutions and there is professional medical staff to coordinate completion.Peritoneal dialysis is then low to patient body situation demand, more
Number patient can row peritoneal dialysis treatment；Secondly, a kind of continuity therapeutic modality of peritoneal dialysis room, closer to the physiology mistake of people
Journey, it is small to hemodynamic effects, be conducive to protect residual renal function；Again, peritoneal dialysis is a kind of family therapy mode, main
It to be performed by patient and family members, medical care guidance makes patient preferably return family, return society.Have in peritoneal dialysis numerous excellent
While point, the shortcomings that it also exists simultaneously it, most important shortcoming is that chronic peritoneal dialysis causes peritonaeum blood vessel hyperplasia, peritonaeum
Thicken, peritoneal fibrosiss and eventually lead to ultrafiltration failure, patient have to terminate peritoneal dialysis treatment.Thus, it much grinds at present
Study carefully or carrying out exploring the mechanism of peritoneal fibrosiss and how prevent.In order to more preferably understand internal peritoneal fibrosiss
Pathologic process, peritoneal dialysis animal model are best experimental models.But existing peritoneal dialysis catheters are when being placed in abdominal cavity
It needs to open abdominal cavity, wound is big, and peritonaeum is influenced greatly, to be unfavorable for restoring, conduit can not be fixed intraperitoneal, and animal is in activity
Conduit is easily deviate from, and catheter length can not be adjusted, and when exposed too long on the outside, animal can be baited, and influences dialysis experiment.Mesh
Preceding market is there is not yet the dedicated peritoneal dialysis catheters of animal model.Because current most peritoneal dialysis zooperies are short-term
Experiment, the intraperitoneal perfusion method that short-term peritoneal dialysis person selects has direct injection device to be injected intraperitoneally or self-control conduit is short temporarily
It dialyses in phase, therefore the situation of many posterior peritoneum of puncture repeatedly damages or self-control dialysis catheters posterior peritoneum adhesion is not obvious.And
Uremic patient needs long-term peritoneal dialysis to sustain life even to the end of life, and the most of patients peritoneal dialysis service life is
Several years or even more than ten years or many decades.And experimental model seldom really simulates the chronic peritoneal dialysis of human body substantially at present.I
Animal peritoneal dialysis catheter in addition to simulation people's peritoneal dialysis catheters function other than, additionally use emerging macromolecule material
Material, is known as the polyurethane (polyurethane) of " the fifth-largest plastics ", histocompatbility is good, is made using this material
Conduit can be not easy to be wrapped to form fiber great waves by peritonaeum with longer-term persistence intraperitoneal, so as to increase the effect of peritoneal dialysis.
In conclusion problem of the existing technology is：
(1) existing peritoneal dialysis catheters are big to peritonaeum wound when being placed in abdominal cavity, are unfavorable for restoring；
(2) conduit can not be fixed intraperitoneal, easily be deviate from；
(3) catheter length can not be adjusted, and when exposed too long on the outside, animal can be baited.
(4) penetration damage peritonaeum repeatedly, is unfavorable for abundant peritoneal dialysis.
(5) existing conduit material is easily wrapped up intraperitoneal by peritonaeum, be easy to cause catheter blockage and can not continue into
Row peritoneal dialysis.
Solve the difficulty and meaning of above-mentioned technical problem：
Difficulty is to lack the dedicated peritoneal dialysis catheters of animal model；Meaning is to be more convenient to carry out animal model abdomen
Film dialysis experiment, so as to more preferably understand the pathologic processes of internal peritoneal fibrosiss, help to explore the mechanism of peritoneal fibrosiss and
How to prevent.
