A hemodialysis system including one or more ultraviolet chambers is disclosed. The hemodialysis system including a dialyzer arranged and configured to filter a patient's blood, a hemodialysis machine arranged and configured to pump, move, or the like dialysate through the dialyzer, the hemodialysis machine including an outlet valve and an outlet fluid flow path to pump or move dialysate from the hemodialysis machine to the dialyzer, and an inlet valve and an inlet fluid flow path to pump or receive dialysate from the dialyzer, and one or more ultraviolet chambers arranged and configured to kill bacteria, viruses, or a combination thereof. Thus arranged, by incorporating one or more ultraviolet chambers in strategic areas of the system, the ultraviolet chambers may eliminate, or at least greatly reduce, the possibility of cross-contamination in, for example, the dialysate, and thus eliminate the need for disinfecting the system between treatments.

A hookah device (202) which attaches to a hookah (246). The hookah device (202) comprises a plurality of ultrasonic mist generator devices (201) for generating a mist for inhalation by a user. The hookah device (202) comprises a driver device (202) which controls the mist generator devices (201) to maximize the efficiency of mist generation by the mist generator devices (201) and optimize mist output from the hookah device (202).

An exhalation assembly that controls the pressure of exhaled gas in a ventilation system is described. The exhalation assembly includes a filter body and a condensate trap. Additionally, a filter/trap module that includes a filter body and a condensate trap is also described.

Systems, methods, and devices related to removing fluids from a patient are provided. In one instance, fluid is removed from the patient and delivered to a canister using reduced pressure. Reduced pressure is supplied to the canister via a reduced-pressure delivery conduit that includes a moisture processing device and a hydrophobic filter. The moisture processing device condenses moisture from the air to prevent condensation from occluding the hydrophobic filter. The moisture processing devices includes an expanded volume and one or more liquid-impermeable, vapor-permeable membranes. The liquid-impermeable, vapor-permeable membrane allows vapor to egress the moisture processing device. Other systems, methods, and devices are presented.

This invention provides a universal respiratory equipment cap which can be used to effectively block a number of different medical devices used in the respiratory care units of hospitals, EMT vehicles and the like. The cap has a small end and a large end, each with blocks or plugs of different diameters. A middle section has a flange which is tapered, thereby allowing for the blocking of additional diameters of tubes and devices. The flange creates two cavities into which anti-bacterial pads can be inserted to further enhance the effectiveness of the device.

An isolation chamber and disinfection system. The novel system includes an enclosure for providing a sturdy, lightless and soundproofed environment and for containing a solution for supporting a user in a state of floatation; a disinfection system for disinfecting the solution, the disinfection system including an ultraviolet disinfection system and an ozone injection system; and a pump for removing the solution from the enclosure and circulating it through the disinfection system at a predetermined flow rate. The enclosure is formed from interlocking, foam-insulated panels and lined with a potable liner that holds the solution. In relationship to the isolation chamber, in accordance with the present teachings, an improved method of disinfection is taught using UV radiation with ozone injection. Ozone has a short half-life and leaves substantially no toxic byproducts. Verification of disinfection can be accomplished by monitoring the dissolved ozone, which can be determined accurately utilizing a dissolved ozone sensor system.

The present invention relates to a mask and an inflatable structure thereof. The inflatable structure which is provided in a mask's body comprises: a ventilation seat; a sleeving connection which is sleeved at one end of the ventilation seat and sandwiches the mask's body together with the ventilation seat, with the sleeving connection provided with a socket tube so that the mask's body, the ventilation seat and the socket tube are in air communication; an air-sealed hood which is connected to the sleeving connection and provided around the socket tube. By virtue of the structure in the present invention, the air flow can be effectively imported into the patient to significantly increase the survival rate of the patient.

Air impeller devices for providing assisted ventilation during spontaneous breathing are described. The devices include a motor; a fan driven by the motor, and a casing defining a housing for the fan. The housing is connectable through a single inlet and outlet port to a respiratory mask, wherein a pressure inside the housing is adjustable according to a rotational speed of the fan such that, in use, an inspiration air flow and an exhalation air flow circulate substantially through the inlet and outlet port. A kit including such an air impeller device and a respiratory mask is also disclosed.

Apparatus and methods for inhibiting the odor of an anesthesia mask, and thereby reducing patient anxiety, generally comprising the use of a towelette treated with a pleasant odorant or flavorant to wipe down a piece of medical equipment, generally a piece of non-metallic or plastic equipment, such as a breathing mask, prior to it being positioned on a patient, and in a location on the patient where the odorant or flavorant can be smelled or tasted.

The disclosure describes an exhalation valve sensor assembly. The disclosure describes a novel exhalation valve sensor assembly that is configured for refurbishing. Accordingly, the disclosure further describes systems and methods for maintaining an exhalation valve assembly and describes a kit for refurbishing an exhalation valve sensor assembly.
