摘要:
A medical device for separating a fluid, in particular for separating platelet-rich plasma from whole blood, comprises three containers (10, 20, 30) and at least one corresponding connection line (40) having an intermediate bifurcation (41). Provided on the connection line (40) are valve means (42, 45, 47a, 48a-48b) for enabling or preventing a flow of fluid. At least one container (10) comprises a hollow container body (11) and a plunger (12) associated in a movable way to the container body (11). The device (1) has a modular structure comprising a plurality of modules (A, B, C), which are connected together in a separable way, for enabling separation thereof according to the step of use of the device (1), and include at least one first module (A), which comprises at least the first container (10) and a corresponding portion (40a) of the first connection line (40), and a second module (B), which comprises at least one between the second and third containers (30, 20) with a corresponding portion (40b, 40c) of the first connection line (40). Provided at least at the interface between two modules (A, B, C) of the modular structure are releasable connectors (43, 44), in particular hydraulic connectors comprising at least two parts that can be coupled together, each of which belongs to a corresponding module (A, B, C).
摘要:
A heater device comprises a supporting body (5) and a plurality of heating elements in the supporting body (5). Each heating element includes a first electrode (14), a second electrode (15), and a material having a PTC effect (16) arranger at least in part between the two electrodes (14, 15). The first electrodes (14), respectively the second electrodes (15), are set at a distance apart in the supporting body (5), with the first electrodes (14) generally parallel to and facing the second electrodes (15). The first electrodes (14) are connected to a first common electrical conductor element (17), and the second electrodes (15) are connected to a second common electrical conductor element (18), and the material having a PTC effect (16) comprises a plastic-based or polymeric-based material moulded or overmoulded at least in part between facing surfaces of the first and second electrodes (14, 15). The supporting body (5) is formed at least in part with a plastic material overmoulded at least in part on the first shaped lamina (19), on the second shaped lamina (20), and on the material having a PTC effect (16).
摘要:
The invention relates to a sensor (2-2 IV ) for detecting the density and the viscosity of a liquid fuel, in particular for a vehicle, comprising a sensing element (4, 4 III , 4 IV ) placed in contact with said liquid fuel and near a reference element (28, 28 I , 28 II , 28 III , 31), so as to affect the motion of the liquid fuel flow by increasing the viscous friction effect of the sensing element (4, 4 III , 4 IV ), so that the resonance frequency of said sensing element (4, 4 III , 4 IV ) will be affected more by the density and viscosity of said liquid fuel.
