Embodiments relates to an advance type of portable hydrogen ventilator, which mainly includes: main body, main battery, function board, electrolytic sheet, electrolytic cell and end cover; wherein the bottom of the main body is provided with a battery, the side is provided with a function key, and the top of the main body is closed by an end cover; one side of the function board is connected with a battery, the other side is connected with an electrolytic sheet, and the function board is provided with a function Key; the electrolytic piece is fixed on the main body and placed in an electrolytic cell; the top of the electrolytic cell is provided with a hydrogen filtering chamber. By fixing the electrolytic sheet on the main body, the utility model is convenient for disassembly and replacement, and the electrolysis process is better controlled through the cooperation of the function key and the function sheet. At the same time, the problem of electrolyte leakage is avoided; the utility model has the advantages of simple structure, high gas production quality, convenient operation and low cost.

A conduit for a breathing circuit includes a heater associated, at least in part, with a hydrophilic layer. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked up by the hydrophilic layer. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.

A system is disclosed for recovering autologous thrombin from a blood product. The blood product is drawn into an injecting syringe and a clot is allowed to form. A discharge port of the injecting syringe is communicably connected to an intake port of an aspirating syringe through a hydrophilic filter assembly. The injecting and aspirating syringes are simultaneously operated to transmit blood product through the filter such that fibrous clotting material and red blood cells are removed by the filter and a concentrated, high-quality thrombin solution is recovered.

Handheld carboxy therapy applicators are disclosed. In one implementation, a handheld carboxy therapy applicator includes a heater module, a humidification module, and a hypodermic needle. The heater module is configured to receive a flow of gas and to warm gas within the flow of gas. The humidification module is in fluid communication, such as in a serial connection, with the heater module. The humidification module is configured to receive the flow of gas from the heater module and to humidify the gas within the flow of gas. The hypodermic needle is in serial connection with the humidification module. The hypodermic needle is configured to receive the flow of gas from the humidification module and to inject the flow of gas into a tissue of a patient.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

A disposable transfer device has an injection device support surface for receiving an on-body injection device thereon and a flow path arrangement for transfer of fluid into the injection device, the transfer device being configured to define preferential gripping areas for user gripping of an injection device when such device is located on the support surface and interfering areas for interfering with user gripping of the injection device in the interfering areas.

A breathing circuit having a semipermeable membrane, an outer cage, and optionally an inner cage. The semipermeable membrane contains a poly(tetrafluoroethylene) membrane and a graphene anti-bacterial compound. The semipermeable membrane is affixed to the outer cage; optionally between the inner cage and the outer cage. Breathing circuits and breathing systems may contain such a cartridge.

Skin-contact products with a transpiration function such as medical devices or medicinal products, of which face masks, aspirators, ventilators, breast pumps or wound dressings are examples are described especially a skin-contact product with a transpiration function with an improved microclimate at a patient interface material-skin contact area. In an embodiment a material system is described that comprises a hydrophobic silicone base material and a hydrophilic silicone material that is combined with the hydrophobic base material.

A wound dressing according to certain embodiments includes an adhesive layer for adhering the wound dressing adjacent to a wound, a wound contact layer for contacting the wound, a backing layer comprising a port, a tube having a first end connected with the port and an opposite second end, a first fitting connected to the second end of the tube, the first fitting configured for connection with a second fitting of the negative pressure wound therapy system to apply a negative pressure via the port, and a filter disposed within the first fitting. In certain embodiments, the filter is formed of polyethersulfone (PESU) and has an average pore size of at least 2 microns.
