Apparatus for carrying out peritoneal dialyses
First Claim
1. An apparatus for conducting peritoneal dialysis comprising at least one flexible container for handling a fluid useful in said peritoneal dialysis, supply means for supplying said fluid to said at least one flexible container, weighing means for weighing the contents of said at least one flexible container, a conduit connected to said at least one flexible container for conducting a flow of said fluid, enclosure means surrounding said at least one flexible container thereby forming a space between said at least one flexible container and said enclosure means, and pressure control means for altering the pressure within said space for transferring said fluid from said at least one flexible container through said conduit.

Abstract
Apparatus for carrying out peritoneal dialysis. The apparatus comprises a weighing device (37) provided with a case (50) for forming an airtight space. A heat bag (38) and, optionally, a discharge bag (42) are positioned in the space, said bags being connected with a catheter for the patient, who is to perform peritoneal dialysis. The apparatus comprises a pump arrangement (57) connected with the case (50) for producing overpressure and underpressure, respectively, in the space inside the case. Valve arrangements (39, 44) are adapted to connect either the discharge bag (42) or the heat bag (38) with the patient'"'"'s catheter. By providing an underpressure in the case (50). fresh dialysis solution is provided to the heat bag (38) from supply bags, whereupon used dialysis fluid is extracted from a patient to the discharge bag (42). By causing an overpressure in the case (50), a fresh and heated dialysis solution is supplied from the heat bag (38) to the patient, whereupon the discharge bag (42) is drained to a waste or to collection bags. The flow of dialysis solution is monitored by the apparatus by means of weighing the case (50) and its contents. Suitable data for the treatment is stored in a memory unit of the apparatus.
