The invention relates to a balloon catheter device (1) for use in an aorta of a rabbit or a human being. The device (1) comprises a balloon catheter (2), a syringe (3), an actuator (4), a pressure sensor (5), a balloon retracting unit (6), a first control unit (7) and a second control unit (8). The balloon catheter (2) comprises a flexible tube (10) and a balloon (11) at a distal end (12) of the tube (10) and the syringe (3) comprises a chamber (16) containing a fluid, wherein the chamber (16) is connected to a proximal end of the tube (10). The actuator (4) is adapted for increasing/decreasing a volume of the fluid contained within the balloon (11). The pressure sensor (5) is adapted for sensing an inflation pressure of the balloon (11) and the balloon retracting unit (6) is adapted for retracting the balloon (11) out of the aorta. The first control unit (7) is adapted to receive pressure data representing the inflation pressure of the balloon (11) measured by the pressure sensor (5) and to control the actuator (4) depending on the received pressure data, such that the inflation pressure of the balloon (11) is kept stable at a predefined inflation pressure value, and the second control unit (8) is adapted to control the balloon retracting unit (6), such that the balloon (11) is retracted out of the aorta at a constant speed.

A method and process for providing three dimensional (3-D) virtual image of a patient in metaverse for surgical or other procedures, wherein the avatar of a medical practitioner, imitating the actions of the practitioner performing the procedure, can visually identify the organs and the location of the instruments in real-time inside patient. Such an image reconstruction with spatial coordination provides a usable metaverse implementation with the medical professional's persona as avatar, usable as a training and supportive tool in medical applications. It is a very valuable, especially for the medical and surgical community. The implemented Metaverse provides all details collected and combined from the multiple imaging systems. It is usable as a diagnostic tool, a practice tool a teaching tool and real time direction and feedback tool by the medical community for procedures. The real-time image implemented as Metaverse provides critical visual capabilities during procedures.

Disclosed are methods, materials and devices for approximation of blood volume in a fluid, such as in a biological fluid collected during a surgical procedure. The method and devices include the use of a RBC flocculant, such as polyDADMAC, and an approximate blood hematocrit for the type of animal, as well as a calculated RBC packing ratio corresponding to the collection device being used. Also provided is a Blood Indicator Panel (BIP), comprising a series of markings calculated from an observed red blood settlement volume, the average animal type hematocrit, and a calculated RBC packing ratio ? value for the collection device. Pediatric (about 200 ml or 250 ml size container), adult human (about 1,000 ml-1,500 ml) and veterinary (about 500 ml-2,500 ml) collection containers are also disclosed, that include a RBC flocculant, for use in approximating blood volume in a fluid.

Bird carriers and methods of restraining birds are disclosed. Each bird carrier may include a torso support, one or more leg clamps, and a head support. The head support may further include a beak receiving passage such that at least a portion of the birds' beaks are exposed. The bird carriers may restrain one or both legs and heads of the birds while supporting their torsos. Restraining the legs and the heads of the birds while supporting their torsos may produce a calming effect such that the birds exhibit significantly reduced struggling in an attempt to free themselves from the carrier.

A medical device that includes a plurality of members forming a body that can transition from a delivery configuration to a deployed configuration. The plurality of members form a plurality of openings each with a long axis extending substantially longitudinally relative to a longitudinal axis of the medical device in a delivery configuration. A plurality of end portions are associated with a distal portion of the medical device, the end portions extending towards the longitudinal axis in a deployed configuration.

A syringe includes a first syringe barrel and a second syringe barrel. Each barrel includes a delivery end to which an end piece with a channel is secured, a piston which is arranged movable in the syringe barrel and can be moved towards the delivery end in order to deliver a fluid located between the delivery end and the piston via the channel. The two syringe barrels are mechanically connected to each other such that the distance between them cannot be changed. At least one of the two end pieces can be secured to the allocated delivery end in different positions for adjustment of the distance between the two channels.
