A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethsmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

A fixture is provided for attachment to a device to be inserted into a nasal cavity. Further, the fixture is a nasal cavity insertion device fixture formed of a wire rod. The fixture includes a first wire rod part, a second wire rod part, and a third wire rod part. The second wire rod part is connected to the first wire rod part and formed by folding back the wire rod so as to be opposed to the first wire rod part. The third wire rod part is connected to the second wire rod part and formed by bending the wire rod so as to be disposed oppositely to a side of the second wire rod part facing the first wire rod part.

Described here are devices and methods for measuring a distance in an airway. In some instances, the devices may comprise an outer shaft and an inner shaft that is slidably disposed in a lumen of the outer shaft. An expandable stopper may be positioned at a distal end of the inner shaft, which may be configured to engage a carina of a patient. The device may comprise one or more alignment markings and one or more displacement markings that may be used to measure a distance between a distal tip of an endotracheal tube and the carina. In some variations, measurement may be facilitated by the use of an alignment guide that may attach to a predetermined portion of an endotracheal tube.

A fluid dispensing catheter including an elongate body having a proximal portion and a distal portion and defining a passage between the proximal and distal portions, and a plug having a proximal section positioned within the passage in the distal portion of the elongate body to partially occlude the passage, the plug being substantially cylindrical and having a flat parallel to and offset from a longitudinal axis of the plug, the flat defining a gap with the elongate body.

The present invention provides medical devices comprising at least one visualization device sealed to, attached to or otherwise combined with at least one of the following second devices: an oral airway, ventilating mask, urinary catheter, trocar, a tool tube, and a medical glove. The present invention also provides methods for rapid and accurate placement of a medical device in a patient and continuous real time monitoring, including a remote monitoring, of the patient after the placement.

A patient tube securement apparatus is disclosed that may be used for oral or nasal intubation of a patient.

The apparatus may comprise an endotracheal tube securement apparatus for securing an endotracheal tube to a patient, the apparatus comprising a dermal patch arranged to be positioned on the skin of the patient, and at least one tube holder on the dermal patch.

The apparatus may comprise a patient tube securement apparatus for securing a patient tube to a patient, the apparatus comprising a dermal patch arranged to be positioned on the skin of the patient, and at least one tube holder on the dermal patch.

Examples are provided in which the tube holder is adjustably mounted on the dermal patch such that the position of the tube holder on the dermal patch can be adjusted without removing the dermal patch from the skin of the patient.

Described herein are examples of pharyngeal respirators. Pharyngeal respirators may include a connection end having a first outer width, a flange disposed on the connection end having a second outer width greater than the first outer width, and a socket disposed on the flange. The connection end may be insertably disposed within a receiver of a pharyngeal breathing tube. The flange may not fit within the receiving end of the pharyngeal breathing tube. The socket may receive a medical fitting. The connection end, the flange, and the socket may form a tubular structure having a first end comprising the connection end and a second end comprising the socket.

Some implementations of the disclosure are directed to a balloon dilator system, including: a balloon pump hand piece configured to pump pressurized fluid through a flexible tube to inflate an inflatable balloon, the balloon pump hand piece comprising: an attachment mechanism for removably coupling the balloon pump hand piece to a proximal end of an endoscope; the flexible tube, wherein the flexible tube is configured to be in fluid communication with the balloon pump hand piece at a first end of the flexible tube, and the inflatable balloon at a second end of the flexible tube; a hollow inner cannula; and the inflatable balloon, wherein the inflatable balloon is external to and circumferentially attached to the hollow inner cannula between the proximal end of the hollow inner cannula and the distal end of the hollow inner cannula.

A heating device for heating surgical tubes is disclosed herein. The heating device comprises a hollow housing configured to receive the surgical tubes therein. A heating element provided on the hollow housing. A first sensor is assembled on the heating element and configured to sense the temperature of the heating element. A controller is coupled to the heating element and the first sensor, wherein the controller is configured to receive an input associated with a required heating temperature from a user for heating the surgical tubes, and accordingly regulate the operation of the heating element based on the required heating temperature and an actual temperature sensed via the first sensor.

A head frame apparatus is secured to a human head during maxillofacial surgery and includes devices to easily position and secure an endotracheal (breathing) tube and an anesthesia delivery circuit for the patient that reduces the likelihood that the flow of oxygen through the tube is restricted thereby reducing the risk of severe injury or death. The head frame apparatus also includes a removable reference indicator, which may be easily attached and removed while identifying a reference point of the patient's face. Also the reference indicator includes a universal joint and pointer with an attached ruler. A transport apparatus positions multiple preset reference indicators and allows for preoperative transportation and removal, while protecting the preset reference indicators from inadvertent adjustment. A bendable reference indicator used in an articulator for preoperative modeling allows for easily identifying reference points in a cast model. An orbiting segment apparatus positions a portion of a cast of a jaw in relation to a condyle ball of the articulator.
