A red, green, and blue values for a fluid are received. A standard red, green, and blue values for the fluid are determined. A tolerance red, green, and blue values are determined for the fluid based on the standard red, green, and blue value for the fluid. An updated red, green, and blue values for the fluid are received. Whether any of the updated red, green, and blue values for the fluid are outside of the associated tolerance red, green, and blue values for the fluid is determined.

Distinctly keyed male-female couplers are pneumatically connected to medical ventilator by distinct lines carrying pulsatile gas or sensory signals. Ventilator-mounted female coupler has entranceway cavity and larger receiving cavity delimited by catch edge. Male fence-forming longitudinal winglets extend from sealing plate carry terminal end convexities which latch onto catch edge. Winglets move inward due to larger fence circumference than entranceway and seat on catch. Winglets placed in tension due to locking length less than entranceway span, then convert force into sealing compressive force between sealing plate and female tube end. Conjoining male tube bayoneted and sheathed by projecting female tube, resulting in another gas seal. Two compressive seals formed between male distal port and pneumatic line. Extending male key(s) on winglet insertable into matching female slots. Convexities block insertion of non-matching couplers set due to interference by convexities on female on entranceway edges.

A display for outputting information contents of at least one parameter, adjustment value or measurement value of medical devices within at least one display region, wherein the at least one display region is in the form of a tachometer-like display.

Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound contact layer, an absorbent layer over the wound contact layer, the absorbent layer comprising one or more apertures, a cover layer configured to cover and form a seal over the wound contact layer and the absorbent layer, and an electronics assembly comprising a negative pressure source. The cover layer can be configured to be compressed within the aperture in the absorbent layer when negative pressure is applied to the wound dressing apparatus and indicate a level of negative pressure below the cover layer. In some embodiments, the wound dressing apparatus can comprise an indicator material layer configured to protrude when negative pressure is applied to the wound dressing apparatus and indicate a level of negative pressure below the cover layer.

An airway stabilization system including an airway device and a securing mechanism or faceplate therefor is provided which includes active stabilizing components on both the airway device and the faceplate which prevent clinically significant movement of the airway device with respect to the patients vocal cords in response to the application of significant forces in any direction to the device, be they longitudinal, torsional/rotational or bending. The system includes an airway device and an attached retention collar which interacts with a securing device/patient to ensure proper airway insertion depth and provide unparalleled strength and stability against movement. The airway stabilization system includes a unique stabilizer readily adapted for use in field situations to releasably engage or release a retention structure on the airway device to facilitate ease of application in all conditions, a twist-off 15 mm connector which allows a secure connection of the 15 mm connector to the airway device while facilitating easy disconnection thereof, and a universal bite block which cooperates with the securing system to prevent oral and/or dental damage and discomfort to the patient when the system is installed.

A needle and syringe system, wherein a needle head is attached to a syringe assembly. The syringe assembly includes a syringe barrel and a plunger rod with a plunger head. A needle base is affixed to the syringe barrel. A tubular cavity is formed in the needle base and a post extends through the tubular cavity. A needle extends through the post. A spacer is provided. The spacer is displaced into the tubular cavity within the needle base as the plunger head is advanced within the syringe barrel. A protective cover is disposed about the needle base. The spacer moves the protective cover between a first position and a second position as the spacer is displaced into the tubular cavity. As the protective cover moves between positions, the protective cover surrounds the needle and prevents the needle from causing any inadvertent needle stick injuries.

An on-body drug delivery device having a housing carried by a substrate. The substrate includes one or more cut-outs and/or one or more perforations to allow the substrate to better conform to the patient's body.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.

The invention relates to a drug delivery device comprising: a syringe with a body from which a needle extends and an inner sheath; a piston rod comprising a piston and an actuation head, a support sheath for holding the body. It is envisaged that the support sheath and the actuation head comprise corresponding indicators.

A portable modular assistive device for storing, measuring, drawing and administering liquid injectable medication or other fluids from a vial and syringe, specifically to insulin for consumers and medical professionals in homes, while traveling and in medical facilities, having means to allow users to quickly, securely, easily and accurately measure and draw the desired amount of insulin and then administer the medication. The device is a portable syringe guide and vial holder comprising a horizontal elongated stabilizer made of rigid light-weight material with high tolerance and low friction, a rigid liquid medication vial protector at one end; a rigid movable syringe carriage with an opening on the top side to firmly hold the assembled syringe and needle to perfectly align the needle to the center section of the rubber top of the vial; a flexible expandable color-coded security strap; a flexible expandable color-coded resistance spacer ring, a removeable adjustable magnifier and calibrator bar, a rigid end cap at the other end of the horizontal stabilizer, with said holder having means to allow users to transport said holder in a pocket or pouch without risk of spillage from the vial, dislodging the components or damage to the vial, needle or syringe. Thus, a considerably more versatile, cost-effective, durable and efficient syringe guide and vial holder is provided that can accommodate a plurality of syringe and needle sizes as well as various liquid medications and other fluids in vials in the first embodiment as well as in other embodiments with ease of tracking quantities, contents, sizes and locations of a variety of vials, syringes and needles.
