At least some aspects of the present disclosure feature a convective device, comprising: a pneumatic structure formed by one or more layers, a partially detachable access duct, and a separation device disposed on a side of the partially detachable access duct. The partially detachable access duct in fluid connection with the pneumatic structure.

A hot air producing system produces and stores hot air, and applies the stored hot air to a human body. The system includes a heating apparatus to heat the air, a temperature setting gauge to allow a user to set a desired temperature, a pressure gauge to measure a pressure of the air in the container, a pump to pump the hot air, a fill connection, an expandable container for receiving and storing the hot air, with a valve to connect to the fill connection such that the expandable container can receive the hot air, an adjustable flow release mechanism to allow a user to adjust an amount of flow of hot air out of the expandable container, and a flexible hose connected to the adjustable flow release mechanism, with a nozzle to direct the hot air to a portion of the human body.

A heat exchange module having a heat transfer fluid channel and a heat transfer plate in heat transfer relation with fluid in the channel. The reference side of a thermoelectric cooler (TEC) is in thermal contact with the plate. A heat transfer tile is in thermal contact with a user side of the TEC. The module is configured to be operatively positionable with the tile in heat transfer relation with skin of a patient.

A medical device for warming a patient. The medical device includes bed configured to support the patient thereon and a heater configured to produce heat for the patient when supported on the bed. A temperature sensor is configured to detect an ambient air temperature apart from the bed. A controller is provided in communication with the temperature sensor, where the controller produces a signal based on the ambient air temperature from the temperature sensor.

An electric heating pad for warming a patient. The electric heating pad may be a heated underbody support, heated mattress or heated mattress overlay. An embodiment of the heating pad includes a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges. The heating pad may also include a shell covering the heating element and comprising at least two sheets of flexible material (e.g., two sheets may be one sheet folded over to form at least two sheets). The two sheets of flexible material may be coupled together about the edges of the heating element by a weld. The material of the two sheets may include urethane. In some embodiments, a catalyst to accelerate hydrogen peroxide decomposition is coated on or impregnated into an element within the shell, or on the interior surface of the shell.
