Abstract

An apparatus for carrying out peritoneal dialysis on a patient having a catheter ending in a patient connector, includes a tubing set in a "Y" configuration, including a first, second and third arm. Each arm has a clamp and terminates in a connector. Along with the "Y" tubing set are also provided a cover for covering and protecting the patient connector after the tubing set has been disconnected, and a closure for sealing a dialysate container after it has been emptied, so that it can be used in a subsequent procedure as a drain bag.

Claims

1. A method for carrying out peritoneal dialysis on a patient whose peritoneal cavity is in fluid communication, via a tubular pathway, with a threaded patient connector, utilizing an apparatus comprising:

a tubing set having first, second and third tubing arms, each tubing am having a first end and a second end, the first end of each tubing arm being connected to and in communication with the first ends of the other two arms,

first connecting means on the second end of the first tubing arm, said first connecting means being threaded and adapted to be connected to said threaded patient connector,

second connecting means on the second end of the second tubing arm, said second connecting means being adapted to be connected to a fresh dialysate container,

third connecting means on the second end of the third tubing arm, said third connecting means being adapted to be connected to a drain bag,

clamping means at an intermediate location of each tubing arm,

threaded cover means for engaging, covering and protecting the patient connector after the tubing set has been used and disconnected, said threaded cover means being initially closed by a threaded cap, both the cover means and its cap being filled with disinfectant,

closure means for sealing a dialysate container after it has been emptied,

said method comprising the steps;

a) closing all said clamping means,

b) then in any order;

threadably connecting the first connecting means to the patient connector, connecting the second connecting means to a fresh dialysate container, and connecting the third connecting means to a drain bag,

then in consecutive order;

c) opening the clamping means on the second and third tubing arms,

d) allowing sufficient time for dialysate from said container to flow through the second and third tubing arms and into the drain bag, thus flushing the second and third tubing arms,

e) closing the clamping means on the second tubing arm,

f) opening the clamping means on the first tubing arm,

g) allowing dialysate in the patient'"'"'s peritoneal cavity to drain into the drain bag,

h) closing the clamping means on said third tubing arm,

i) opening the clamping means on the second tubing arm and allowing dialysate to flow from the container into the patient'"'"'s peritoneal cavity,

j) closing the clamping means on the second tubing arm,

k) closing the remaining clamping means,

l) disconnecting the patient connector from said first connecting means by unscrewing,

m) removing the cap from the cover means by unscrewing, then in any order;

n) thereby connecting the cover means to the patient connector, and

o) threadably connecting the cap to said first connecting means.

2. The method claimed in claim 1, in which, after all of the dialysate in a given container has been transferred to the patient'"'"'s peritoneal cavity, said given container is re-used as a drain bag.

3. The method claimed in claim 1, in which the apparatus includes at least one cartridge containing disinfectant, the cartridge being adapted to close and disinfect said second connecting means, whereby the tubing set can be used for more than a single dialysis treatment.

4. An apparatus for carrying out continuous ambulatory peritoneal dialysis on a patient whose peritoneal cavity is in communication, via a tubular pathway, with a threaded patient connector, the apparatus comprising:

a tubing set having first, second and third tubing arms, each tubing arm having a first end and a second end, the first end of each tubing arm being connected to and in communication with the first ends of the other two arms,

first connecting means on the second end of the first tubing arm, said first connecting means being threaded and adapted to be connected to said threaded patient connector,

second connecting means on the second end of the second tubing arm, said second connecting means being adapted to be connected to a fresh dialysate container,

third connecting means on the second end of the third tubing arm, said third connecting means being adapted to be connected to a drain bag,

clamping means at an intermediate location of each tubing arm,

threaded cover means for covering and protecting the patient connector after the tubing set has been used and disconnected, the cover means being closed by a threaded cap, both the cover means and the cap being filled with disinfectant, said cap being adapted to threadably seal said first connecting means after disconnection of the tubing set from the patient connector, while the cover means threadably closes and protects the patient connector, in order to allow the patient to completely disconnect from the tubing set during the peritoneal dialysis phase of the treatment, prior to reconnecting back to the same set to continue with the treatment,

closure means for sealing a dialysate container after it has been emptied, and

wherein said closure means is a closed spike, said second connecting means being an open spike.
