Apparatus for supporting a syringe includes a handle portion and a cradle. A clip is provided for connecting the plungers of two or more syringes, and two or more syringes are operated by placing one in the cradle and attaching the clip to the plungers for simultaneous operation of the plungers. The handle portion also forms a cavity for storing the clips. The apparatus is preferably used in combination with an applicator tip that combines the outputs from the two or more syringes.

Apparatus for holding and operating one or more syringes

A method, and apparatus for transferring a fluid to a sterile field includes the use of a sterile enclosure () housing a syringe (). The enclosure () is made in two parts, and allows the syringe () to be operated while it is in the enclosure. When it is desired to pass the fluids to the sterile field, the enclosure is separated into at least two parts to allow the syringe to be removed. This removal of the syringe is done such that the user in the non-sterile field does not touch the syringe. Thus, the syringe, and fluid therein are easily transferred to the sterile field.

Apparatus for the sterile transfer of fluids

A self-contained portable unit for heating physiological fluids is disclosed. A heat exchanger is disposable to ensure sterility, and the hot exchanger is attached to a heating system by inserting it between opposed fluid connection elements. One of the fluid connection elements is movable to permit the heat exchanger to be installed and removed easily by inserting one end of the heat exchanger in one of the fluid connection units and moving the other fluid connection unit into contact with an opposite end of the heat exchanges. The heating fluid is heated by an electric heating element and is circulated by an electric pump.

A system for the collection of physiological fluids includes a vacuum source ( ) that is controlled to provide low vacuum as a function of whether fluids are entering the system. The suction wand and associated tubing are made of thin flexible materials, and the pressures employed do little damage to the collected fluids.

System for collection of blood without damage

The invention comprises a disposable tubing set ( ) for connection to a rigid canister ( ) that is maintained at a controlled reduced (vacuum) pressure. The set is used for collecting and anti-coagulating a patient's blood for later re-infusion into the same patient

System for withdrawal of blood

A system for collection of blood during surgery includes an interlock that requires conduits supplying collected blood to a bag to be properly connected before the system is operated. The interlock includes a source of electromagnetic energy that illuminates connectors to determine whether they are connected. In a preferred embodiment, the connector is a Luer connector with a cylindrical portion that redirects the electromagnetic energy when the connector is in place.

Container with integral pump platen

A flexible, integral polymer resistance heated conduit is provided that is particularly suitable for use with physiological fluids. The conduit is highly effective in uniformly heating a fluid and in maintaining the fluid at a uniform, predetermined temperature. The conduit is inexpensive and easy to manufacture, and is at least partially transparent or translucent, thereby allowing easy viewing of its contents.

A gas elimination device for cellular fluids has a cylindrical chamber that is divided radially into two parts by a cylindrical filter centrally located in the chamber. The fluid inlet is directed tangentially to the outer part of the chamber to create a vortex flow. The vortex flow is stopped by passage of the fluid through the filter, and gas bubbles that have formed rise to the top of the outer part of the chamber. A hydrophobic membrane covers the top of the chamber and allows the gas to exit the chamber to the atmosphere. A one way valve formed in a two part cap covering the chamber prevents flow of air into the chamber. A float valve stops flow when the chamber fills with air.

An injection site designed for use with a needleless syringe includes a housing placed in an infusion line and an inlet for engaging the syringe and conveying a fluid to be mixed with the infusate to the interior of the housing. A liner within the housing controls flow of fluid through the inlet by sealing the inlet when the pressure in the housing is equal to or exceeds the pressure in the syringe. The housing is made of two parts, each of which includes a flange. When assembled, the spaced flanges are on opposite ends of the liner, which is not directly attached to the housing, to limit movement of the liner to maintain its position in the housing.

A heater for physiological solutions that is effective at low and high flow rates includes first and second heat exchangers that have different fluid heating characteristics. The first heat exchanger is capable of heating solutions at high flow rates, while the second heat exchanger is designed to heat the solutions at low flow rates. A warming fluid is circulated through the heat exchangers, and a manifold is provided to control the flow of the warming fluid that is directed to the two heat exchangers. The solution to be warmed is directed to both heat exchangers such that a warmed solution is provided irrespective of the flow rates.

Heater for physiological solutions effective at both low and high flow

A device for reducing the amount of a gas contained in a liquid includes a central core with an inlet channel, an outlet channel, and a transverse channel. A first chamber is formed on a first side of the core for receiving the liquid from the inlet channel, and a second chamber is formed on the opposite side of the core for receiving the liquid after it has passed through the first chamber. Each of the chambers includes a hydrophobic membrane for allowing gas that has separated from the liquid to pass to the atmosphere. The two chambers are arranged such that gas escaping from the liquid rises to the top of at least one of the chambers for any orientation of the device. The device, accordingly, is not dependent on orientation for effectiveness.

Orientation-independent device for removal of gas from a cellular fluid

A heat exchanger useful for supplying infusates over substantial distances uses an extrusion which provides a central tube for carrying an infusate and two outer channels for carrying a heat exchange fluid. A first of the channels carries the heat exchange fluid from an inlet end to an opposite end, and the other of the channels returns the heat exchange fluid to the inlet end. An end cap at the inlet end is easily connected to a source of heat exchange fluid and communicates with the channels. An end cap at the opposite end receives the heat exchange fluid from the first channle and redirects it to the second channel. Both of the end caps have connectors for facilitating connection with lines from a source of infusate and a patient.
