摘要： A heat exchanger has a laminar fluid flow path receivable between the heating plates of a high flow rate infusion unit to which heat is conducted by contact with the heating plates. A bubble trap and a valve are integrated with the heat exchanger. The bubble trap collects air from the infusate exiting the laminar flow path, and includes an air vent in contact with the infusate that vents the air from the bubble trap. The valve shuts off the flow of infusate if air is detected in the bubble trap.

摘要： A forced air warming unit has a casing with inlet and outlet openings. The casing encloses a scroll housing with a curved inside surface in which a blower is disposed. A circuit board in the casing encloses the blower in the scroll housing. At least one opening penetrates the circuit board. A heater plate is disposed between the circuit board and the blower. The blower draws air through the inlet opening, along a first side of the circuit board through the at least one opening into the scroll housing. The blower also forces air along a second side of the circuit board which faces the scroll housing, through air passages in the circuit board, along the first side through the at least one opening, into the scroll housing. The blower accelerates air along the curved inside surface and past the heater plate. Heated, pressurized air exits through the outlet opening.

摘要： An air blower unit operates with reduced noise while providing a stream of warmed air. The blower unit includes a housing with an inlet at a first end and an outlet at a second end. A support positions the housing above a support surface such that the inlet points toward the support surface, and the outlet does not point away from the support surface. A rotatable blower creates an airstream by flowing air into the housing through the inlet and out of the housing through the outlet. The outlet is coupled to a delivery conduit having an elbow that absorbs some noise from the blower, and reflects remaining noise downward. The delivery conduit my be connected to a convective thermal blanket, for example. A motor, mechanically linked to the blower, rotates the blower and resides in the housing upstream of the blower. A heater, interposed between the blower and the motor, heats the fluid stream as it passes the heater.

摘要翻译： 鼓风机单元以降低的噪音工作，同时提供暖气空气。 鼓风机单元包括壳体，其具有在第一端处的入口和在第二端处的出口。 支撑件将壳体定位在支撑表面上方，使得入口指向支撑表面，并且出口不指向远离支撑表面。 可旋转鼓风机通过入口将空气流入壳体并通过出口流出壳体来产生气流。 出口连接到具有弯头的输送导管，该弯头吸收来自鼓风机的一些噪音，并将剩余的噪声反射下来。 例如，输送导管连接到对流热毯上。 机械地连接到鼓风机的马达使鼓风机旋转并驻留在鼓风机上游的壳体中。 介于吹风机和电动机之间的加热器在通过加热器时加热流体流。
