A neck fan, configured to be worn around a neck of a user, includes: an inner shell, disposed near the neck; an outer shell, connected to the inner shell and disposed opposite to the inner shell and away from the neck, wherein the outer shell and the inner shell cooperatively define a receiving space; a plurality of fan assemblies. Each fan assembly is received in the receiving space and connected to the inner shell and the outer shell. Each of the inner shell and the outer shell defines a plurality of air inlets, each fan assembly corresponds to both the air inlets in the inner shell and the air inlets in the outer shell, each of the plurality of fan assemblies is configured to intake air from an outside of the neck fan into the receiving space through the corresponding plurality of air inlets.

A method of preparing cryogenic air for use in cryotherapy procedures, characterized in that liquid nitrogen (1) is fed from a cryogenic nitrogen tank (2) via a cryogenic duct (3) to at least one exchanger (4), wherein at the same time a breathing mixture (6), containing oxygen in a concentration of 17% to 100%, is fed, via an oxygen duct (7), from a breathing mixture (6) source (5), through the filter (8), to at least one exchanger (4), then in at least one exchanger (4), by means of a heat exchange between the breathing mixture (6) and liquid nitrogen (1), the breathing mixture (6) is cooled to the set temperature of minus 80° C. to minus 160° C., and then the cooled breathing mixture (6) is fed from at least one exchanger (4), via an upper pipe (9).

Systems and methods for treating a body region are provided herein. A treatment device for treating a body region is provided, and may include a first applicator and a second applicator. The first and second applicators are held on the body region by a belt. The first applicator may include a first magnetic field generating device and a radiofrequency electrode. The second applicator may include a second magnetic field generating device. The first and second magnetic field generating devices may each generate a time-vary magnetic field with a plurality of sequential magnetic impulses to cause muscle contraction in the body region. The radiofrequency electrode may provide radiofrequency waves causing heating of tissue within the body region. The treatment device may further include an energy storage device and a switching device. The switching device my discharge energy from the energy storage device to the first or the second magnetic field generating device to generate the time-vary magnetic field.

A neck fan includes an arc-shaped shell and a fan assembly. The arc-shaped shell is configured to be worn around a neck of a user. The shell has a first side and a second side opposite to the first side. Each of the first side and the second side defines air inlets. At least one of the first side and the second side defines air outlets. The shell further defines a receiving space, and the receiving space includes an air duct communicating with the air inlets and outlets. The fan assembly is received in the receiving space and configured to drive the air to flow from the air inlets of both sides, through the air duct, reaching the air outlets.

The present invention provides a cold air therapy device (1) for applying a cooled air flow to a body surface, comprising: cooling means (2) configured to cool the air flow to be applied to the body surface; air guiding means (3) coupled to the cooling means (2) and configured to direct the air flow, in order to direct the air flow to be applied to the body surface, which is cooled by the cooling device (2), to a cold air outlet (4); and an air disinfection device (5) which is configured to at least reduce the germ load and/or the bacterial load of the air flow to be applied to the body surface.

A self-contained, hyperthermic conditioning unit and selectively controllable environment for exercising. The unit comprises a base portion having a bed therein and a removable cover connected to the base portion to enclose a personal compartment within the unit. One or more heating elements provide heat to the personal compartment and one more pieces of physical exercise equipment are provided within the personal compartment.

A treatment system delivers a breathing gas and frozen stem cells or other biologic particles (FBP) to a bronchus of a lung of a patient in order to treat lung and other conditions. The breathing gas and the FBP are usually delivered through separate lumens. The FBP may be delivered concurrently with other frozen particles, such as frozen saline particles (FSP). The FBP/FSP will remain frozen at all times from preparation to delivery, and will thaw only after they are released into the lung.

An apparatus and method for providing heat exchange in the lungs of the mammal during partial liquid ventilation are provided. The apparatus and method can control delivery and removal of partial liquid ventilation to the lungs of a mammal by responding to pressure change in the lungs to minimize danger of causing barotrauma to the patient.

A neck fan includes an arc-shaped shell configured to hang around user's neck and at least four fan assemblies arranged in the shell. The shell includes a first part and a second part. Each of the first part and the second part defines an accommodating space, air inlets and air outlets communicated with the accommodating space, at least one partition is arranged in the accommodating space and configured to divide the accommodating space into at least two accommodating parts arranged along an extension direction of the shell. Each of the fan assemblies is arranged in one of the at least two accommodating parts and is configured to direct air into the one of the at least two accommodating parts through corresponding air inlets and to direct air out of the one of the at least two accommodating parts through corresponding air outlets.

A head-mounted heat dissipation device includes a fan assembly and a wearing assembly. The wearing assembly is connected to the fan assembly to fix the fan assembly onto a head of a user. The fan assembly includes a casing and fans arranged in the casing. Air inlets and air outlets are defined in the casing. The air outlets are located on an inner side of the bottom surface of the casing, so that the air from the air outlets can be blown to the user's face. In addition, air guide strips are arranged side by side on a side of the air outlet within the casing for concealing the operation of the fans.
