An air separator () comprises a first chamber () where blood or other fluid can be received, an inlet and an outlet port associated to the bottom wall () and in fluid communication with the first chamber. A first channel () extending along the lateral wall of the separator and has a first and a second portion (and). The channel second portion () terminally forms an orifice () facing the chamber and extending in an area closer to a top wall () of the chamber () than to the bottom wall of the same chamber. The orifice faces the top of the separator and has a flow passage cross section greater than that of a first portion () of the channel.

Air separator for extracorporeal fluid treatment sets

A rigid tubular piece and a cassette assembly for extracorporeal blood circulation having the rigid tubular piece are disclosed. The rigid tubular piece is used for submitting fluid circulating therein to measurements and includes a protrusion or a recess in correspondence of at least an end connector. A blood treatment medical apparatus using the cassette assembly is also disclosed. The apparatus is able to detect if the right rigid tubular piece is in proper position before authorizing measurements of a blood property.

Disposable extracorporeal blood circuit and apparatus for the extracorporeal treatment of blood

In an infusion apparatus, an infusion line () connects a container () of an infusion fluid to an extracorporeal blood circuit (). A first valve () closes the infusion line downstream of an infusion pump (). An expansion chamber (), provided with a pressure sensor (), is arranged between the infusion pump and the first valve. A second valve () closes a vent line () of the expansion chamber. The processor closes the first valve when the container is emptied. After replacement with a new and full container, the processor restarts the pump and selectively opens the first valve or the second valve according to the increase in pressure measured in the expansion chamber.

Infusion apparatus

An apparatus for hemo(dia)filtration comprises an extracorporeal blood circuit and a supply line of a replacement fluid to the extracorporeal blood circuit. The supply line has a bifurcation which divides a main branch () into a pre-dilution branch () and a post-dilution branch (). A pump tube tract () is predisposed in the supply line for coupling with a circuit pump of the replacement fluid. An expansion chamber is predisposed in the extracorporeal blood circuit and is fluidly connected to the pre-dilution branch. The invention provides a disposable fluid circuit usable for performing a hemodiafiltration treatment with pre-dilution and post-dilution which is couplable simply, rapidly, economically and reliably to a machine for monitoring the treatment.

Hemo(dia) filtration apparatus

An extracorporeal blood chamber () comprises an expansion reservoir () having a first access () arranged laterally and a second access () arranged on the bottom of the chamber (). The chamber comprises, integrally with the reservoir, a first conduit terminating in the first access, a second conduit terminating in the first access, and a third conduit terminating in the second access. The extracorporeal blood enters the reservoir through the first conduit and there mixes with an infusion fluid which enters through the second conduit. The resulting mixture exits through the third conduit. The chamber is used in a hemo(dia)filtration apparatus to mix the blood optimally with the replacement fluid.

Extracorporeal blood chamber

In a blood transfer chamber, a filter () is arranged at an outlet located on a bottom of the chamber. The filter is truncoconical with a vertically-disposed axis. The filter has a plurality of openings () for fluid passage, a size of which openings increases gradually in an upwards direction going from bottom to top of the chamber. The filter is used in a venous air-blood separation chamber of a dialysis set. The invention enables a reduction of a risk of hemolysis during treatment as well as a reduction of the risk of formation of air bubble retention in the filter during a priming stage.

Blood transfer chamber

An extracorporeal blood circuit, comprising an expansion chamber for air-blood separation, wherein a filter () retains the solid particles in the blood. The filter has a trunco-conical filtering wall with a vertical axis surmounted by a top head () provided with upper openings () conformed and arranged such as to define a fluid passage which is asymmetrical with respect to the vertical axis. The top head does not retain air bubbles internally thereof, thus preventing a situation in which the air bubbles are directed towards an outlet of the expansion chamber and thus towards the patient. The extracorporeal circuit is used in a dialysis apparatus.

Extracorporeal blood circuit

A rigid tubular piece () and a cassette assembly () for extracorporeal blood circulation having the rigid tubular piece are disclosed. The rigid tubular piece is used for submitting fluid circulating therein to measurements and includes a protrusion or a recess in correspondence of at least an end connector. A blood treatment medical apparatus using the cassette assembly is also disclosed. The apparatus is able to detect if the right rigid tubular piece is in proper position before authorizing measurements of a blood property.

In an infusion circuit (), a peristaltic pump () displaced the infusion fluid along a line (), sourcing it from a batch container (). When a weight sensor () detects an emptying of the batch container (), the pump is halted. If on stopping the pump the pressure measured by a sensor () operating in an expansion chamber () does not drop in excess of a predetermined threshold with respect to a non-empty container (), a non-secure situation is signalled, due to an excessive quantity of air in the expansion chamber.

Cassette for dialysis

Module for fluid transport of medical fluid and blood

The transducer-protector device for medical apparatus comprises a housing formed by two half-shells, a membrane defining a gas-permeable anti-contamination barrier, a female Luer first connection port, a second connection port for connection to a flexible tube, a helical bellows-conformed deformable member. The device, which operates in a service line of an extracorporeal blood circuit associated to a dialysis machine, is for protecting the machine from contaminating agents originating from the circuit. The device is simple and economical to manufacture.

Transducer-protector device for medical apparatus

A rigid support element for an infusion line for medical use has a first and second portion rigidly connected to each other and capable of holding a first length of tubing. The first portion incorporates a continuous separator for separating fluid into a gaseous portion and a liquid. This separator has a containing body formed on a support element and a pair of membranes, one hydrophobic and one hydrophilic, interacting with each other.

Support element for an extracorporeal fluid transport line

An infusion device for medical use has a container designed to hold a specified quantity of a liquid to be infused into a patient, a weighing device associated for operation with the container to measure the weight of the container and emit a corresponding signal, a transport line connected to the container, a pump, and a control unit associated with the weighing device and with the pump. The control unit is capable of detecting the end of infusion condition and of commanding the pump to stop the transport of fluid. A separator for continuously separating fluid into a gaseous portion and a liquid portion operates in the infusion line downstream of the pump and prevents the infusion of gas during the stopping transient of the pump at the end of infusion.
