Infusion fluid warmer
The present invention relates in one aspect to an infusion fluid warmer which comprises a casing shell having an upper wall structure and a lower, opposing, wall structure. The casing shell encloses a fluid channel or passage extending through the casing shell in-between the upper and lower wall structures and fluid inlet and outlet ports coupled to opposite ends of the fluid channel or passage to allow a flow of infusion fluid through the casing shell. A housing shell is formed in a thermally conducting and electrically insulating material and a heating element is bonded to the housing shell and thermally coupled thereto. The fluid channel or passage extends through the housing shell or extends around the housing shell such that heat energy is transferred to the infusion fluid by direct physical contact with housing shell material.

Heated patient tube assembly
A heated patient tube assembly that carries and gradually warms fluids to a desired temperature and maintains the desired temperature until the fluids are delivered to a patient includes an elongated hollow tube; a heating assembly at least partially embedded within the tube for heating the tube and fluids carried in the tube; and a control assembly for controlling the heating assembly such that the fluids exit the tube at a desired and consistent temperature.

Systems, methods, and devices for artificial placentas and amniotic bed incubators
Described herein are systems, devices, and methods for an extracorporeal, artificial, placenta. In some embodiments, an artificial placenta and amniotic bed system may comprise a control unit, a gas delivery unit, a gas exchange unit or membrane oxygenator, a fluids delivery unit, an amniotic fluid bed, and a human machine interface. In some embodiments, the artificial placenta and amniotic bed systems, devices, and methods described herein may improve survival rates and minimize long-term disabilities in preterm, gestational-age, newborns. In some embodiments, the extracorporeal systems, devices, and methods comprise an artificial network through which oxygen and nutrient-rich blood may flow into a fetus (residing in an amniotic fluid bed), while carbon dioxide and wastes may be removed, thus re-establishing a form of intrauterine placental circulation.
Thermal system with drainage bag
A drainage bag is provided for a thermal control unit adapted to deliver temperature-controlled liquid to a patient in order to control the patient's temperature. The drainage bag is used to hold and transport the liquid when the liquid inside the thermal control unit is changed. The drainage bag includes a bottom layer, a top layer sealed thereto, and a float secured to the top layer that is positioned adjacent an opening in the top layer. As the liquid from the thermal control unit drains into the opening in the top layer, the liquid lifts the float and the float lifts the top layer of the bag. The bag thereby expands its volume to accommodate the liquid from the thermal control unit. The bag may further be designed to be carried without sealing the opening and without spilling the liquid. A method for using the bag is also disclosed.

Bursitis treatment device and method
A bursitis treatment device (100; 200) for treatment of inflammation of a bursa (150; 502) in a patient's joint includes: a rinsing aid; a reservoir (101; 201) for holding the rinsing aid in fluid, freezing fluid or gaseous state; a supply line (103; 204, 208) for transporting the rinsing aid; a heat exchanger (104; 203) for controlling the temperature of the rinsing aid—such that the temperature of the rinsing aid enables to destroy cells causing the inflammation; an access device (209) for injecting the rinsing aid into the bursa (150; 205); and a drain (105; 210) for removing the rinsing aid from the bursa (150; 205) for elimination.
Syringe with temperature modulation capabilities
Disclosed herein are syringes having temperature modulation capabilities particularly with regard to changing the temperature of the material being ejected from or injected into the syringe and methods of use. In a specific embodiment of this invention, the syringe comprises a phase transition composition which is to be maintained in one phase within the syringe chamber and ejected in a different phase from the syringe.
