Heat treatment apparatus for inactivating viruses in blood includes a series of four tubing coils with connectors at the opposite ends of the series for connecting the tubing to a blood source and a blood destination, a microwave heating chamber arranged to receive the first coil of the series, a dwell chamber to receive the second coil of the series, a cooling chamber adapted to receive the third coil of the series, and a microwave reheating chamber to receive the fourth coil of the series, with the first, second, and fourth chambers employing microwave energy for heating the blood as it flows within the coils and providing a radiometer circuit for monitoring the temperatures of the blood in the first, second, and fourth coils to produce first, second, and fourth temperature signals in response thereto, which is responded to by a controller to control the energy producing means to impart a selected time/temperature profile to the blood flowing through the tubing and to deliver that blood at a selected delivery temperature.

A container system configured to transfer heat to a fluid contained within the container system, such as dialysate. The container system may be configured to fluidly couple to a medical machine. The container system includes a flexible material comprising a wall of the container system. In examples, the flexible material defines a container volume configured to contain the fluid. The flexible material mechanically supports a circuit configured to generate and transfer heat to the fluid. The circuit is configured to flex and/or bend when the flexible material flexes and/or bends. In examples, the container system includes control circuitry configured to cause the circuit to generate heat based on a temperature of the fluid.

A humidification arrangement can be configured to have multiple compartments with each compartment having at least one moisture source and at least one heater. The compartments can be thermally isolated and can be controlled such that the moisture output of both the first and second compartments is set to a function of the same set of input signals.

A hollow fiber membrane laminate that includes a plurality of hollow fiber membranes wound to form a plurality of layers in a cylinder shape. The hollow fiber membranes are wound around a central axis while reciprocating a feeding point of the hollow fiber membranes along a central axis. Hollow fiber membranes adjacent to each other in each respective layer are separated by a predetermined separation distance. A speed differential z is reduced for successive layers approaching an outer side of the cylinder to maintain the predetermined separation distance. The speed differential z has a value obtained by dividing a pitch of the hollow fiber membranes within a respective layer by a traverse reciprocating distance.

The present disclosure provides a liquid constant temperature heating apparatus, an infusion device and a formula milk preparation device. The liquid constant temperature heating apparatus includes: a heating portion, the heating portion having a heating chamber, and the heating chamber having a liquid inlet and a liquid outlet; a liquid inlet pipe, the liquid inlet pipe being connected with the liquid inlet of the heating portion; a liquid outlet pipe, the liquid outlet pipe being connected with the liquid outlet of the heating portion; a temperature sensor, the temperature sensor being arranged on the liquid outlet pipe and in communication with the heating portion; and a controller, which is in signal connection with the temperature sensor by a signal and configured to control heating of the heating portion according to a measurement result of the temperature sensor.

An artificial lung device includes: a housing which is formed in a tubular shape including both end portions closed, includes a blood inflow port and a blood outflow port, and is arranged such that a center axis of the housing is directed in a lateral direction; a hollow fiber body (gas exchanger) which is arranged in the housing and performs gas exchange with respect to blood while the blood flows from the blood inflow port to the blood outflow port; and a straightening frame (gas guide portion) by which a gas having flowed through the gas exchanger by the flow of the blood is guided to the gas exchanger again in the housing.

The present application relates to a method for disinfection of a temperature control device for human body temperature control during extracorporeal circulation which temperature control is conducted by use of a heat exchanger and a temperature control liquid circulating through the heat exchanger and the temperature control device. According to the present application, the temperature control device is connected to a temperature control liquid supply and, during operation of the temperature control device for human body temperature control, a disinfectant is selectively added to the temperature control liquid supply upstream of the temperature control device.

Disclosed is a local cooling anesthesia device for spraying a coolant on a treatment site. The local cooling anesthesia device includes a housing which forms an outward form and from which the coolant is sprayed and a spraying unit installed in the housing to spray the coolant. The device also includes a cooling temperature regulator connected to the spraying unit to apply thermal energy to the sprayed coolant for temperature regulation and a control unit connected to the cooling temperature regulator to control the cooling temperature regulator. The cooling anesthesia device has functions of measuring and regulating the temperature of the coolant, and thus can apply the coolant to the treatment site within a safe temperature range according to the purpose of treatment, thereby enabling a desired treatment purpose such as local anesthesia to be safely and rapidly accomplished without side effects such as cytoclasis.
