A connector for a component of a medical breathing circuit. The connector comprises an inner body and an outer body. The outer body is configured to be slidable along the inner body between each of an inoperative orientation and an operative orientation with respect to the inner body. The outer body and the inner body are configured to be in engagement or in an operative association with each other when the outer body is provided in the operative orientation. The outer body and the inner body are disengaged from each other or in an inoperative association with each other when the outer body is provided in the inoperative orientation. At least one or each of a surface of the inner body or a surface of the outer body comprises of a surface relief feature(s) providing for a resistance to the outer body being moved from the inoperative orientation to the operative orientation.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration. A system and method for fusing independent measures of the physiological parameters, in some examples using a Kalman filter for each possible combination of sensor measurements.

This apparatus produces a capnogram for a patient, comprising airflow means arrangeable such that air flowing into and out of a patient during a breathing cycle of the patient are conducted through the airflow means; a CO2 monitor (50) for repeatedly determining the presence, and level, of CO2 in the air within the airflow means; an airflow direction sensor for distinguishing between periods when air is flowing into the patient, when air is flowing out of the patient, and when air in the airflow means is stationary; a processor for producing a graph on a display of time versus an indication of CO2 levels, wherein the display includes different graphical qualities to distinguish between the level of CO2 in the air flowing out of the patient, the level of CO2 in the stationary air between breaths, and the level of CO2 in the air flowing into the patient.

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.

A breathing apparatus includes a control unit configured to control operation of the breathing apparatus based on at least a first input value and a second input value. The breathing apparatus also includes a graphical user interface connected to the control unit. The control unit is configured to display a visual output on the graphical user interface including an area defined by a first axis and a second axis. In addition, the breathing apparatus includes an input unit configured to provide selection of a portion of the area. The control unit is configured to set the first input value in response to the position of the selected portion relative the first axis and to set the second input value in response to the position of the selected portion relative the second axis.
