Abstract: A suspension of a therapeutic substance (e.g., embolic beads) dispersed within a liquid can be delivered via a catheter by using a bidirectional pump to rapidly draw the mixture of the therapeutic substance and liquid from an external syringe into an internal reservoir, then rapidly push the mixture back out into the external syringe. The rapid operation of the bidirectional pump mixes the two constituents so that the therapeutic substance is temporarily suspended within the liquid. Then, a low-speed pump is used to inject the mixture out via the catheter. In some embodiments, the parameters of the low-speed pump are controlled so that the fluid exiting the catheter will experience laminar flow. When the therapeutic substance comprises embolic beads, this can advantageously prevent reflux of the embolic beads, which can be dangerous.

Abstract: In a pressure compensation type flow rate control valve, overshoot of a flow rate when an upstream pressure is abruptly increased is suppressed. A first variable orifice 11 is provided on the side of an inflow opening and a second variable orifice 15 is provided on the side of an outflow opening. As the spool 3 is displaced from its initial position by a pressure of fluid entering when the upstream fluid pressure is increased, the opening of the first variable orifice 11 is gradually reduced, and the opening of the second variable orifice 15 is gradually increased. Since the second variable orifice 15 on the side of the outflow opening is previously reduced, even if the upstream pressure is abruptly increased, fluid more than a predetermined amount does not flow out toward the downstream.

Abstract: A water system uses a pressure reservoir of an extremely small size. A valve device is placed between a water pump and the pressure reservoir. The valve device has a constant outlet pressure to limit the flow from the pump at high pressures. The pump is turned on and off by a pressure on/off switch. The valve device maintains the pressure to the reservoir at or below the on switch pressure except for a trickle flow. The trickle flow fills the reservoir when there is little or no water usage from the reservoir.

Each time the valve opens any debris in the notch is washed from the notch thereby keeping the notch free of debris. Back flow of the trickle is prevented with a roll seal valve by restricting the trickle to a flow path and incorporating a check valve in the flow path.
