This document describes medical systems that use artificial intelligence to facilitate autonomous or semi-autonomous medical procedures. For example, this document describes heart/lung machine systems that are used in conjunction with artificial intelligence systems to facilitate autonomous or semi-autonomous open-heart surgery operations.

Semi-autonomous medical systems and methods

A blood parameter measurement cassette or other device is configured to control incidental liquid discharged during the device's calibration process. The cassette includes optical sensors which are chemically responsive to blood constituents and require calibration with a blood parameter monitoring device prior to use in a medical procedure. During the calibration process, an incidental amount of a liquid may be expelled from the cassette. The present invention is directed towards controlling the expelled liquid by absorbing it using an absorbent material disposed on the exterior of the cassette's main body. The absorbent material thereby prevents the liquid from causing detrimental effects to the monitoring and calibration equipment used in conjunction with the cassette. The scope includes additional embodiments wherein the inventive concept is applied to other fluid-handling medical devices that require venting of gases.

A tubing set for use with a blood handling system is described that decreases the priming volume and surface area of the blood handling circuit, lowering the risk of hemodilution, platelet activation, and hemolysis. The tubing set also reduces the number of manual connections required, and uses quick-disconnect couplings to facilitate connections between the various lines, and between the lines and the arterial and venous cannulae.

Tubing set for blood handling system and methods of use

A device for supporting and displaying interrelated medical components, such as cardiopulmonary bypass circuit components. The device includes a rigid or flexible chassis having openings therein for receiving the components. A plurality of retainers, such as straps, hooks, or tabs, are provided adjacent the openings for releasably securing the components therein. The chassis may be formed of a thin, flexible polymer sheet having tabs cut therein and adapted to be bent out of the plane of the sheet for securely retaining the various components. The pre-arrangement of the components in close proximity greatly simplifies the task of setting up a particular medical circuit, and reduces the potential for error. For cardiopulmonary bypass circuits, the support device enables the tubing lengths to be reduced, thus reducing the prime volume of the circuit. The chassis is provided with apertures for mounting on rods in the operating room, which rods may extend from the operating table. Handles are also provided on the chassis for conveniently transporting the components or circuit. The compact nature of the chassis and components thereon simplifies and reduces the cost of packaging and shipping. In addition, disposal of a used circuit is facilitated by the provision of a clean bag around the entire system. A pumpless cardioplegia delivery system is also provided.
