Abstract
Abstract A process for peritoneal dialysis, whose main characteristic consists in comprising: a first phase during which an end of a first tube (2) branched from a pocket (1) containing a dialyzing solution, and an end portion (35) of a second tube (24) containing a disinfecting liare connected to one another; a second phase during which the dialyzing solution contained in the peritoneal cavity of the patient is allowed to flow through the said second tube (24) and through a third tube communicating with the said first (2) and second (24) tubes; a third phase during which the dialyzing solution contained in the pocket (1) is introduced into the peritoneal cavity; and a fourth phase during which the said first (2) and second (24) tubes are disconnected and the said end portion (35) is filled with disinfecting liquid and closed hermetically.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
360 words
- A process for the peritoneal dialysis, characterized in comprising: - a first phase during which a first end of a first tube (2) communicating by means of a second end with the interior of a pocket (1) containing a dialysing solution is connected to a first end portion (35) of a second tube (24) having a second and opposed end portion (34) communicating with the peritoneal cavity of a patient; the flow along the said first (2) and second (24) tubes being discontinued by first (36) and second (32) interception means respectively, and the said first and second end portions (35, 34) of the said second tube (24) containing, respectively, a disinfecting liquid and a part of a dialyzing solution contained in the said peritoneal cavity; - a second phase during which the flow within the said second tube (24) is enabled so that the said dialyzing solution, contained in the said peritoneal cavity, and the said disinfecting liquid contained in the said first end portion (35) of the said second tube (24) will flow towards the outside through the said second tube (24) and a third tube (7, 41) which communicates with the said first (2) and second (24) tubes between the said first (36) and second (32) interception means; - a third phase which takes place at the end of the flow of the said dialyzing solution from the said peritoneal cavity and during which the flow along the said third tube (7, 41) is discontinued and then the flow along the said first tube (2) is allowed to take place so that the said dialyzing solution contained in the said pocket (1) will be introduced into the said peritoneal cavity through the said second tube (24); - a fourth phase during which, in order, the flow along the said second tube (24) is interrupted, the said first tube (2) is detached from the said second tube (24), the said first end portion (35) of the said second tube (24) is filled with a disinfecting liquid, and the said first end portion (35) of the said second tube (24) is sealed by means of a plug (33).
Claim 2
Dependent Claim
360 words
- A process for the peritoneal dialysis, characterized in comprising: - a first phase during which a first end of a first tube (2) communicating by means of a second end with the interior of a pocket (1) containing a dialysing solution is connected to a first end portion (35) of a second tube (24) having a second and opposed end portion (34) communicating with the peritoneal cavity of a patient; the flow along the said first (2) and second (24) tubes being discontinued by first (36) and second (32) interception means respectively, and the said first and second end portions (35, 34) of the said second tube (24) containing, respectively, a disinfecting liquid and a part of a dialyzing solution contained in the said peritoneal cavity; - a second phase during which the flow within the said second tube (24) is enabled so that the said dialyzing solution, contained in the said peritoneal cavity, and the said disinfecting liquid contained in the said first end portion (35) of the said second tube (24) will flow towards the outside through the said second tube (24) and a third tube (7, 41) which communicates with the said first (2) and second (24) tubes between the said first (36) and second (32) interception means; - a third phase which takes place at the end of the flow of the said dialyzing solution from the said peritoneal cavity and during which the flow along the said third tube (7, 41) is discontinued and then the flow along the said first tube (2) is allowed to take place so that the said dialyzing solution contained in the said pocket (1) will be introduced into the said peritoneal cavity through the said second tube (24); - a fourth phase during which, in order, the flow along the said second tube (24) is interrupted, the said first tube (2) is detached from the said second tube (24), the said first end portion (35) of the said second tube (24) is filled with a disinfecting liquid, and the said first end portion (35) of the said second tube (24) is sealed by means of a plug (33).
Claim 3
Dependent Claim
69 words
'- A process as claimed in Claim 1, characterized in comprising between the said first phase and the said second phase an intermediate phase during which the flow along the said first tube (2) is enabled for a pre-established period of time so that a determined quantity of the said dialyzing solution contained in the pocket (1) will flow towards the outside through the said third tube (7, 41).
Claim 4
Dependent Claim
56 words
