Abstract: A syringe piston used in fat transplantation is structured such that free oil is easily separated from suctioned fat by a syringe piston having a filter and naturally discharged through the rear side thereof. The syringe piston without a shaft, used in fat transplantation, disposed in a syringe-shaped cylindrical vessel, includes a piston body without the shaft, a packing coupled with an outer surface of the piston body to seal between the piston body and the syringe-shaped cylindrical vessel, a free oil discharging hole communicated with the front side and the rear side of the piston body, an opening and closing device for opening and closing the free oil discharging hole, and a filtering device disposed in a passage through which free oil is discharged to filter fat and pass the free oil.

Abstract: A subcutaneous valve having a body defining a chamber and including an inlet orifice and an outlet orifice opening out into the chamber, a shutter member suitable for closing the inlet orifice, at least in part, a resilient return member configured to hold the shutter member against the inlet orifice to regulate the passage of liquid through said inlet orifice, and a rotor housed in the chamber having a cam-forming surface, the resilient return member bearing against the cam-forming surface of the rotor by forming a moving contact with this surface.

Abstract: A hemodialysis catheter assembly adapted for use in a subcutaneous tunneling procedure incorporates a mechanism for securing the catheter hub member to the elongated catheter, and to provide the requisite fluid communication between fluid passages within the hub and the catheter lumens within the catheter. The catheter hub member may be connected to the elongated catheter after implantation of the catheter via a subcutaneous tunneling procedure.

Abstract: A catheter includes a tubular body having a channel having its ends opening out respectively at the ends of the tubular body, injector element for injecting fluid into the channel, a tubular endpiece having a channel with ends opening out respectively at the ends of the tubular endpiece, and element for connecting the endpiece and the body together so that the end of the channel and the end of the channel are in alignment on an axis, the connection element being constituted essentially by a ring that partially covers the body and the endpiece, and being also arranged in such a manner that the connection can be broken by exerting a force couple of predetermined value respectively on the endpiece and on the body. The invention is applicable to safety catheters for performing endovascular treatments by injecting embolic fluid, for example for treating arteriovenous malfunctions.

Abstract: A radiation shielding syringe carrier comprising a top cap, a main body and a needle shield, all formed from a radiation dense material. The main body preferably includes a syringe shield shaped to be threadably engaged to the bottom of the carrier. Preferably a separate top cap and shipping cap are provided.

Abstract: A device for protecting an injection apparatus for injecting a product, the said apparatus comprising a needle and a piston connected to an actuating rod surmounted by a piston head, the said device comprising: a support sleeve, a protective sleeve for protecting the needle, first retaining means for holding the protective sleeve in its standby configuration in a first position, second retaining means for holding the protective sleeve in its standby configuration in a second position, an intermediate collar comprising collaboration means for collaborating with the piston head, and deactivation means for deactivating the first and second retaining means. The second retaining means being able to be deactivated by the deactivation means of the intermediate collar by the release of the pressure of the piston head on the collaboration means of the intermediate collar to allow the protective sleeve to deploy under the action of pushing means.

Abstract: The invention concerns an arrangement to couple an intravenous hose having a roller clamp with an infusion pump. A hose clamp has clamping surfaces in the form of legs which can move relative one another about a hinge, the legs being enveloped on their outside by a biased clamping spring, and the device is formed by an expander rib that is fastened on the inside of the door and can be brought into engagement with the legs of the hose clamp so to produce the open position after closing the door to expand the legs. The housing has a receiver, into which the hose clamp can be snapped, and that a locking device is present in the housing that prevents the closing of the door if the hose clamp is not inserted into the receiver and permits the closing of the door when the hose clamp is fully inserted.

Abstract: Injection device comprising a tubular elongated main body, a needle shield slidably arranged in said main body, a needle shield link slidably connected to said needle shield, a enclosure containing medicament arranged in said main body, a needle connected to said enclosure, a plunger operatively arranged to said enclosure for ejecting said medicament through said needle and arranged on its upper part with a number of outwardly extending stop members, spring means arranged to said plunger for operating said plunger, a dose activating means, a needle shield spring surrounding the needle shield link.
