Abstract
The utility model discloses an anti peritoneal dialysis pipe that backflows, including peritoneal dialysis solutions ascending pipe, peritoneal dialysis waste liquid discharge pipe and the anti device that backflows of peritoneal dialysis, peritoneal dialysis prevents backflowing device and peritoneal dialysis waste liquid discharge pipe and concatenates mutually, and both ends all keep unobstructed, the device of preventing backflowing is interior to be set up including buoyancy ball and unhurried current chamber, the unhurried current chamber be an ellipse spherical cavity, upper and lower both ends and the peritoneal dialysis waste liquid discharge pipe is linked together, works as when the unhurried current intracavity is full of the dialysis waste liquid, buoyancy ball will float to unhurried current chamber top, and buoyancy ball contacts with the inner wall in unhurried current chamber, constitutes simple and easy one way switch, forms sealedly to reach the mesh that prevention and cure peritoneal dialysis waste liquid backflowed. But prevent with the unhurried current chamber that the peritoneal dialysis waste liquid from backflowing through setting up buoyancy ball, avoid peritoneal dialysis patient to appear infecting at the treatment in -process, have simple structure, with low costs, advantage that the facilitate promotion was used.
Description
Technical field
The invention belongs to medical instruments field, particularly a kind of anti-reflux peritoneal dialysis catheter.
Background technology
Peritoneal dialysis is the peritoneum utilizing human body self a kind of dialysis as dialyzer.By pouring into the saturating of abdominal cavity
Analysis liquid and the plasma fraction in the blood capillary of peritoneum opposite side carry out the exchange of solute and moisture, the generation being detained in purged body
Thank product and too much moisture, supplement material necessary to body by dialysis solution simultaneously.By constantly changing peritoneal dialysis liquid, reach
Substitute or the purpose of Supporting Therapy to kidney, be that End-stage renal failure or Acute Renal Failure Patients clinic are conventional and have
The renal replacement therapies mode of effect.
But, Patients With Kidney Diseases infects owing to many factors is likely to cause antibacterial when carrying out peritoneal dialysis, severe patient
And then initiation peritonitis, thus cause patient cannot continue to use peritoneal dialysis mode to treat, cause the biggest to patient
Injury, increases the financial burden of patient.And cause factor that antibacterial infects one of them be at dialysis waste liquid from abdominal cavity of patients
When being expelled to external, antibacterial is along with the entrance human abdominal cavity of backflowing of dialysis waste liquid；This phenomenon is frequent in automated peritoneal dialysis
Occur.
Summary of the invention
It is an object of the invention to provide a kind of prevent dialyse waste liquid backflow into a kind of anti-reflux peritoneum of human abdominal cavity
Dialysis tubing.The technical scheme realizing the object of the invention is: a kind of anti-reflux peritoneal dialysis catheter, including peritoneal dialysis solution ascending pipe,
Peritoneal dialysis waste liquid discharge pipe and peritoneal dialysis anti-reflux device；Described peritoneal dialysis anti-reflux device is arranged with peritoneal dialysis waste liquid
Go out pipe concatenation, and two ends all keep clear；Arrange in peritoneal dialysis anti-reflux device and include buoyant spheres and unhurried current chamber, described slow
Stream chamber is an elliposoidal cavity, and upper and lower two ends are connected with described peritoneal dialysis waste liquid discharge pipe, when described unhurried current intracavity is full of
During dialysis waste liquid, described buoyant spheres will float to top, chamber of flowing slowly, buoyant spheres and the contact internal walls in unhurried current chamber, constitutes simple single
To switch, formed and seal, thus reach to prevent and treat the purpose that peritoneal dialysis waste liquid backflows.
The invention has the beneficial effects as follows dialysis waste liquid discharge pipe in concatenate anti-reflux device, by arrange can buoyant spheres and
Unhurried current chamber prevents peritoneal dialysis waste liquid from backflowing, it is to avoid patients undergoing peritoneal dialysis occurs infecting over the course for the treatment of, has structure letter
List, low cost, advantage easy to utilize.
Accompanying drawing explanation
Fig. 1 is a kind of anti-reflux peritoneal dialysis catheter schematic diagram of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows: peritoneal dialysis solution ascending pipe 1, and peritoneal dialysis waste liquid is discharged
Pipe 2, buoyant spheres 3, chamber 4 of flowing slowly, peritoneal dialysis anti-reflux device 5.
Detailed description of the invention
In conjunction with Fig. 1, a kind of anti-reflux peritoneal dialysis catheter of the present invention, including peritoneal dialysis solution ascending pipe 1, peritoneal dialysis
Waste liquid discharge pipe 2 and peritoneal dialysis anti-reflux device 5；Described peritoneal dialysis anti-reflux device 5 is discharged with dialysis waste liquid
Pipe 2 phase concatenates, and two ends all keep clear；Peritoneal dialysis anti-reflux device 5 includes buoyant spheres 3 and unhurried current chamber 4；Described slow
Stream chamber 4 is an elliposoidal cavity, and upper and lower two ends are connected with described peritoneal dialysis waste liquid discharge pipe 2, when filling in described unhurried current chamber 4
Completely during dialysis waste liquid, described buoyant spheres 3 will float to top, chamber of flowing slowly, buoyant spheres 3 and the contact internal walls in unhurried current chamber 4, constitutes
Simple single-way switch, is formed and seals, thus reaches to prevent and treat the purpose that peritoneal dialysis waste liquid backflows.
Peritoneal dialysis solution ascending pipe 1 one end can connect peritoneal dialysis solution, and the other end can connect through operation and insert human body abdomen
The conduit in chamber, peritoneal dialysis solution can enter human abdominal cavity by dialysis solution ascending pipe 1；Dialysis solution discharge pipe 2 one end connects human body
The conduit in abdominal cavity, other end connection is for holding the container of peritoneal dialysis waste liquid.
When waste liquid of dialysing flows to, from human abdominal cavity, the container holding dialysis waste liquid, buoyant spheres 3 moves downward, and makes path beat
Open；Otherwise, if dialysis waste liquid backflows, buoyant spheres 3 moves upward, and buoyant spheres 3 will float to top, chamber of flowing slowly, buoyant spheres 3
With the contact internal walls in unhurried current chamber 4, constitute simple single-way switch, formed and seal, thus reach to prevent and treat what peritoneal dialysis waste liquid backflowed
Purpose.
