Abstract
Medical devices equipment technical field is the utility model is related to, specifically the utility model is related to a kind of peritoneum dialysis catheter.A kind of peritoneum dialysis catheter, including peritoneal dialysis solution ascending pipe, peritoneal dialysis waste liquid discharge pipe and peritoneal dialysis anti-reflux device；The peritoneal dialysis anti-reflux device concatenates with peritoneal dialysis waste liquid discharge pipe, and both ends keep clear；Being set in peritoneal dialysis anti-reflux device includes flow slowly chamber, the first check valve, the second check valve and inflation emptying air bag, the unhurried current chamber is an elliposoidal cavity, upper and lower ends are connected with the peritoneal dialysis waste liquid discharge pipe, when the unhurried current intracavitary is full of dialysis waste liquid, air bag inflating pressure is emptied by inflating, first closed check valve, the second check valve are opened, the peritoneal dialysis waste liquid of emptying unhurried current intracavitary；Waste fluid bag can be improved when patients undergoing peritoneal dialysis activity, because the cut-off of the second check valve acts on, preventing and treating peritoneal dialysis waste liquid backflows, and reaches and allows the purpose of a wide range of activity of patients undergoing peritoneal dialysis.
Description
Technical field
Medical devices equipment technical field is the utility model is related to, specifically the utility model is related to a kind of peritoneal dialysis
Pipe.
Background technology
Peritoneal dialysis be by the use of human body itself peritonaeum as dialysis membrane a kind of dialysis.By pouring into the saturating of abdominal cavity
Analysis liquid carries out exchanging for solute and moisture, the metabolism that removing is detained in vivo with the plasma fraction in the capillary of peritonaeum opposite side
Product and excessive moisture, while pass through material necessary to dialyzate supplement body.By constantly updating peritoneal dialysis liquid, reach
Kidney substitutes or the purpose of supportive treatment, is that End-stage renal failure or Acute Renal Failure Patients are clinical conventional and effective
Renal replacement therapies mode.
However, Patients With Kidney Diseases when carrying out peritoneal dialysis because many factors are likely to cause bacterium infection, severe patient
And then trigger peritonitis, so as to cause patient can not continue to be treated using peritoneal dialysis mode, caused to patient very big
Injury, increases the financial burden of patient.And it is to dialyse waste liquid from abdominal cavity of patients to cause one of factor of bacterium infection
When being expelled to external, bacterium is backflowed into human abdominal cavity with dialysis waste liquid；This phenomenon is frequent in automated peritoneal dialysis
Occur.
If directly to adding a check valve to prevent waste liquid from flowing backwards, due to existing check valve on peritoneum dialysis catheter
Operation principle is realized by the pressure differential at valve both ends, thus when the height of waste fluid bag is higher than the height of waste liquid discharge pipe
When, the pressure differential that check valve both ends will so occur is too small and the problem of check valve can not be opened, such peritoneal dialysis
Waste liquid cannot be transported to well in waste fluid bag.
The content of the invention
It is saturating that the purpose of this utility model is to provide a kind of peritonaeum that a kind of waste liquid that prevents from dialysing backflows into human abdominal cavity
Analysis pipe.The technical scheme for realizing the utility model purpose is：A kind of peritoneum dialysis catheter, including peritoneal dialysis solution ascending pipe, peritonaeum
Dialysis waste liquid discharge pipe and peritoneal dialysis anti-reflux device；The peritoneal dialysis anti-reflux device and peritoneal dialysis waste liquid discharge pipe
Concatenation, and both ends keep clear；Setting in peritoneal dialysis anti-reflux device includes unhurried current chamber, the first check valve, second unidirectional
Valve and inflation emptying air bag, the unhurried current chamber is an elliposoidal cavity, upper and lower ends and the peritoneal dialysis waste liquid discharge pipe phase
Connection, when the unhurried current intracavitary is full of dialysis waste liquid, air bag inflating pressure is emptied by inflating, the first closed check valve, the
Two check valves are opened, the peritoneal dialysis waste liquid of emptying unhurried current intracavitary；Waste fluid bag can be improved when patients undergoing peritoneal dialysis activity,
Because the cut-off of the second check valve acts on, simple single-way switch is formed, forms sealing, preventing and treating peritoneal dialysis waste liquid backflows, reached
Allow the purpose of a wide range of activity of patients undergoing peritoneal dialysis.
The beneficial effects of the utility model are the concatenation anti-reflux devices in waste liquid discharge pipe of dialysing, and are flow slowly by setting
Chamber, the first check valve, the second check valve and inflation empty air bag to prevent peritoneal dialysis waste liquid from backflowing, and avoid patients undergoing peritoneal dialysis
Infect over the course for the treatment of, there is the advantages of simple in construction, cost is low, easy to utilize.
Brief description of the drawings
Fig. 1 is a kind of anti-reflux peritoneum dialysis catheter schematic diagram of the present utility model.
In Fig. 1:1st, ascending pipe, 2, feed liquor bag, 3, rotatable connection folder, 4, inflation emptying air bag, the 5, first check valve, 6,
Second check valve, 7, waste fluid bag, 8, waste liquid sampling end, 9, unhurried current chamber, 10, waste liquid discharge pipe.
Embodiment
With reference to Fig. 1, a kind of peritoneum dialysis catheter of the present utility model, including peritoneal dialysis solution ascending pipe 1, peritoneal dialysis give up
Liquid discharge pipe 10 and peritoneal dialysis anti-reflux device；The peritoneal dialysis anti-reflux device is gone here and there with peritoneal dialysis waste liquid discharge pipe 10
Connect, and both ends keep clear；It is unidirectional to include unhurried current chamber 9, the first check valve 5, second for setting in peritoneal dialysis anti-reflux device
Valve 6 and inflation emptying air bag 4, the unhurried current chamber 9 are an elliposoidal cavity, upper and lower ends and the peritoneal dialysis waste liquid discharge pipe
10 are connected, and when in the unhurried current chamber 9 full of dialysis waste liquid, the inflating pressure of air bag 4, the first check valve 5 are emptied by inflating
Close, the second check valve 6 is opened, the peritoneal dialysis waste liquid in emptying unhurried current chamber 9；Can be useless when patients undergoing peritoneal dialysis activity
Liquid bag 7 is improved, and because the cut-off of the second check valve 6 acts on, forms simple single-way switch, forms sealing, and preventing and treating peritoneal dialysis is given up
Liquid backflows, and reaches and allows the purpose of a wide range of activity of patients undergoing peritoneal dialysis.
During operation, the one end of peritoneal dialysis solution ascending pipe 1 can connect peritoneal dialysis feed liquor bag 2；The connection of rotatable connection folder 3 is logical
Cross the pipe joint that human abdominal cavity is inserted in operation.
Waste liquid discharge pipe 10 connects the unhurried current chamber 9 of peritoneal dialysis anti-reflux device, when patients undergoing peritoneal dialysis is movable on a large scale,
Waste fluid bag 7 can be improved fixation；Pass through waste liquid sampling end（8）Medical worker's sample examination can be facilitated.
