A nasal cannula device according to various embodiments can include a flexible tube, an anti-kink device, and an ear protection device. The anti-kink devices may be attached to or integral with the distal end of the flexible tube that connects to a connection adapter, so that the anti-kink device provides support to the flexible tube to prevent kinking of the flexible tube. The ear protection device may be attached to or integral with a portion of the flexible tube that contacts a user's ear. The ear protection device comprises a soft material to mitigate skin irritation of the user's ear.

A catheter system may include a needle assembly coupled to a catheter adapter. The needle assembly may include a housing, an introducer needle, a distal opening, a first magnet, and a second magnet. In response to proximal withdrawal of the introducer needle, the first magnet may move towards the second magnet, which may block the distal opening and/or prevent blood from leaking out the distal opening.

A patient interface is disclosed which is comfortable for the user to wear and includes at least in part a moisture permeable or breathable area in the body of the patient interface. In another embodiment the patient interface is a strapless mask that is moulded to fit the contours of a user's face and maximise the mask-to-skin seal. An adhesive material is bonded to the mask cushion and is stamped in place to form substantially the same shape as the cushion such that it fits the facial contours of the user.

An aortic adapter assembly is provided, including a T-shaped flow connector, including: an inserted conduit portion, having a blood-contacting surface which is smooth; an extruded neck portion, wherein the inserted conduit portion is joined with the extruded neck portion; and a truss, disposed in the inserted conduit portion; wherein the T-shaped flow connector has a polymeric elastomer reinforced by the truss having a Nitinol material; wherein the inserted conduit portion has an inner wall which is gradually thinning at two conduit ends of the inserted conduit portion, with a proper distance of a tip of the conduit end to the outmost boundary of the truss, and the conduit end possesses a compliance-matching effect to an implant site artery; wherein a proximal end of the extruded neck portion is configured to be joined with an inlet adapter of a blood pump. The aortic adapter assembly is accompanied with a quick-connector type coupler and a deployment method to accomplish an insertion type flow communication between a ventricular assist device and the human circulation.

A pre-filled syringe is disclosed, comprising a barrel and a plunger, the barrel having an outlet, the barrel containing a pharmaceutically acceptable solution having a non-physiological pH, wherein the syringe further comprises an ion exchange material. The ion exchange material is provided at a position to allow contact with the pharmaceutically acceptable solution upon ejection of the pharmaceutically acceptable solution from the barrel via the outlet. The ion exchange material is capable of adjusting the pH of the solution from a non-physiological pH, at which the pharmaceutically acceptable solution is stored in order to ensure acceptable shelf life, to a more physiological pH at which the discomfort and/or pain experienced during injection may be alleviated.

An absorbent cuff for use with a male patient wearing a catheter is provided, the cuff including a nonpermeable body operable to receive and enclose an absorbent material and to prevent leakage of a fluid retained. A circumferentially concave opening is operable for positioning on the catheter below the head of a patient's penis and surround the point of insertion of the catheter into the patient's urethra. A catheter passage is operable to enclose a catheter and to receive and retain fluid discharged from a catheter. A slit enables a catheter to be inserted into the catheter passage of the absorbent material. An absorbent pad operable for use with female patients includes an absorbent material, a nonpermeable backing, a catheter passage, and a slit to allow for insertion and removal of a catheter.

Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.

A respiratory protective mask that prevents carbon dioxide rebreathing is disclosed. The respiratory mask includes a filter element that is dimensioned to cover an opening of a wearer's mouth. A cup like element is configured to rest against and retain the filter element against a wearer's chin. A top extent of the filter element extends laterally across a wearer's lip between a wearer's nose and the opening of the wearer's mouth, when worn. An arm of the filter element is defined by a convergence of the top extent and a lower extent of the filter element. The lower extent that converges upwardly from the cup like element towards a lateral end of the filter element subjacent to a wearer's ear, when worn. A retaining element is attached at the lateral end of the filter element and is configured to removably secure the filter element to cover the wearer's mouth.

A positive airway pressure device includes a blower and a base. A blower outlet passage is connected to the blower and has a central tubular portion and a flexible sealing portion surrounding an outer circumferential surface of the central tubular portion. The base receives a tub with a heat conducting base plate, an internal air passage configured to receive the pressurized flow of respiratory gas from the blower outlet passage, and a pair of tub flanges extending laterally from respective side walls of the tub. Each tub flange has a horizontal portion and a tapered portion. The base further includes a floor with a heater plate a pair of base flanges. Each base flange extends laterally inward from a respective one of the side walls and engages a respective tub flange as the tub is inserted into the base with the tapered portions of the tub flanges being received first.

A cannula system is provided. The system may comprise: a cannula having a hose element having front and rear end regions, wherein a channel extends from the front end region to the rear end region, a hollow body having a front end region, and a connector which, in a connected state of the cannula system in which the front end region of the hollow body is introduced into the channel of the hose element, receives the front end region of the hose element and the front end region of the hollow body in an inner region of the connector. The connector may exert clamping forces on the front end region of the hose element and clamp the front end region of the hose element between the front end region of the hollow body and the connector. Also provided is a blood pump system including such a cannula system.
