摘要： A drip chamber is described that is used in medical infusion therapy, wherein the drip chamber utilizes valving to control flow of one or more fluids to a patient. The drip chamber includes a body forming a chamber, wherein fluid may enter via two or more flow ports, and an output port, where fluid may exit the chamber. A float controls fluid flow through one or more flow ports into the chamber such that the flow exiting the chamber may be limited to a single fluid or a combination of the fluids entering the chamber. The float is configured to be retained within the chamber, and the float moves within the chamber based on a level of fluid within the chamber. The control characteristics of the float are determinable by attributing specific buoyancy and dimensions to the float.

摘要： An intravenous set with an automatic stopping mechanism in the drip chamber comprising a drip chamber (16) wherein the top portion of the drip chamber (16) has a cap (17) with a sharp tooth (18) extending radially outwards for puncturing a container or bottle (15); wherein a lower portion of the drip chamber (16) is connected to a joint or stem (23); wherein the joint or stem 23 is connected to a flexible tube (19) ending in a valve (13) to be connected to a catheter; wherein the flexible tube (19) has a manual flow control device (11); wherein inside the drip chamber (16) contains a stopper (22) for automatic control of flow of fluid from the drip chamber (16); wherein the stopper (22) comprises of a lower part or diaphragm (3), a middle part or stem (4) and a upper part (2); and wherein the stem (4) and the diaphragm (3) are connected by a stud (3), which stud is flexible and a part of the diaphragm (3); and wherein the stopper (22) is submerged as fluid filled in the drip chamber (16), fluid flows through the exit (19) of the drip chamber (16) to cause the stopper (22) to fall, thereby stopping fluid exiting when the diaphragm (3) of the stopper (22) blocks the exit of the drip chamber (16) and fluid in the drip chamber (16) is used up.

摘要： A contrast media delivery system having a flow regulator assembly that allows a practitioner to regulate the passage of contrast media into a burette while minimizing turbulence and the formation of microbubbles in the contrast media. The flow regulator assembly can be actuated by twisting a rotatable cap. When the rotatable cap is released, the flow of contrast media from the inlet to the burette is stopped. A diffuser having a contact surface is provided which disperses contrast media as it passes into the burette to ensure that the contrast media flows smoothly and uniformly down the wall of the burette and into the volume of contrast media. A float and seating assembly which provides optimal sealing of the outlet of the burette while also allowing separation of the float from the seat when the burette is being refilled with contrast media.

摘要： A magnetic automatic stop valve formed in a container of a medical fluid administration system has one magnetic element located in a float and another magnetic element located proximate a valve seat. As the fluid level in the container decreases, the magnetic field established between the float and the valve seat eventually overcomes the buoyancy of the float in the fluid and attracts the float into the valve seat at which position the flow of fluid from the container is stopped. The float is formed of two identical halves each of which has one half of an internal post. When joined together to make the float, the internal post is fully formed and extends from one end of the float to the other. One magnetic element is slid over the post during manufacture and is free to slide from one end of the float to the other. Due to the symmetrical nature of the float and the freedom of movement of the internal magnetic element on the post, the float may be inserted into the fluid container without regard to which direction it faces thus lowering manufacturing costs. Flow seals are provided to completely shutoff flow when the float is seated.

摘要： A perfusion system incorporating a sealed reservoir in communication with a pump which allows any negative pressure at the suction inlet of the pump to be communicated into the reservoir and thereby communicated to any lines connected to the sealed reservoir. The sealed reservoir provides filtration and defoaming elements. An oxygenator and a heat exchanger may be connected to the outlet of the pump to prepare the blood for return to the patient. A control system which operates clamps and displays pressure, temperature, fluid level, and other information measured at various points in the perfusion system, is utilized with a perfusion system. In another embodiment, a hard-shell reservoir utilizing an outlet located at the bottom of the reservoir, said outlet having integral to that outlet a floating ball valve, to where the valve will be opened if there is fluid in the reservoir and closed if no fluid exists in the reservoir.
