A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.

An isolation shroud adapted to enclose and protect a medical gas tank against contamination, which is further replaceable between patients to prevent cross-contamination, comprising a sleeve portion with an open end and interior space, and a hood portion with a hood lower opening, adapted to enclose the body and upper end of the medical gas tank respectively. The hood portion is attached to and is continuous with a sleeve order surrounding the open end of the sleeve portion, allowing the open end and sleeve border to be simultaneously lifted to enclose the body and open end respectively. The hood portion further has a hood front opening, allowing a hose to extend from the medical gas tank outwardly through either the hood lower opening or front opening. A fastener attached to the hood portion further allows the hood lower opening to be sealed against the sleeve portion.

A device for enclosing a positive end valve (PEEP valve) and converting the PEEP valve to an inline valve for use in a differential multi-ventilation system is described. The device includes a housing configured to enclose the PEEP valve. The housing also includes a ventilator-side arm, a pass-through arm and a patient-side arm. The pass-through arm permits extension of the multi-ventilation system to add one or more patients to the system.

A gaming system is provided, including a jackpot server and a gaming server. The jackpot server accumulates respective contributions from gaming client devices into a progressive jackpot. The gaming server presents wagering games to a player on a gaming client device. The wagering games include a first wagering game having a progressive jackpot component, and a second wagering game not having a progressive jackpot component. The gaming server receives a jackpot token from the player, including a token identification associated with the player and a progressive jackpot identification correlating to a token progressive jackpot. A wager is received for the second wagering game, which is conducted such that the player participates in the token progressive jackpot. The gaming server transmits a message to the jackpot server, including a portion of the wager as a contribution to the token progressive jackpot and an outcome of the second wagering game.

A measurement device and a method for monitoring a condition of a patient. The measurement device includes: a gas-guide apparatus, connected between an medical gas provider and a patient and configured to deliver medical gas from the medical gas provider to the patient; and at least one sensing apparatus, placed on an outer surface of the gas-guide apparatus and configured to detect real-time measurement data of the medical gas passing through the gas-guide apparatus. In this way, the at least one sensing apparatus is placed on the outer surface of the gas-guide apparatus, since the measurement data is a relative value which indicates a change of internal environment of the gas-guide apparatus, this can also avoid a problem of contamination compared with setting a sensor inside a respiratory device, thus improving the security of the measurement.

A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.

A peritoneal dialysis (“PD”) system having an air-aided pumping sequence is disclosed herein. In an example, a PD system includes a housing, a PD fluid pump housed by the housing, an airtrap, a fluid line extending from the airtrap, a fluid line valve positioned and arranged to operate with the fluid line, a gas line extending from an upper portion of the airtrap, and a gas line valve positioned and arranged to operate with the gas line. The system also includes a control unit configured to cause the fluid line valve to close, the gas line valve to open, and the PD fluid pump to pump gas from the airtrap into the gas line after a patient drain to create a pocket of gas in the fluid line and push residual used PD fluid towards a drain line.

A syringe for use with a medical injector system includes a barrel and a semi-rigid hub, the hub having an outer surface adapted to slidingly move within the barrel, and an inner surface having a continous circumferential wall. The hub further includes an annular engaging portion recessed within at least part of the continous circumferential wall forming a groove, at least one radially extendable and retractable retention member disposed at partially within a proximal cylindrical portion of the hub, and the elastometric seal engaged with a seal engaging portion on the hub and slidingly engaged with the barrel of the syringe. The semi-rigid hub and the elastomeric seal are reciprocally slidable within the barrel, and the at least one radially entendable and retractable retention member is configured to releasably engage the groove upon retraction of the plunger to permit the semi-rigid hub to be selectively withdrawn within the barrel.

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.

Apparatuses and methods of using them to collect blood, are provided, by first ensuring that the patient's skin is properly cleaned, to prevent contamination of the collected blood. One feature is a blood collection device configured to collect blood from a patient. Another feature is a scrub timer integrated into the device and configured to indicate to a user a scrub time period prior to beginning a blood draw process. The scrub timer can be configured to audibly and/or visually indicate to a user the start and stop times of a scrub cleaning process. In one embodiment, the scrub timer can be restarted, either manually or automatically, if the scrub cleaning process is not followed properly.
