A Lindbergh perfusion pump, c. 1935, an early device for simulating natural perfusion. Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, [1] usually referring to the delivery of blood to a capillary bed in tissue. Perfusion may also refer to fixation via perfusion, used in histological ...
When Lindbergh saw the crudeness of Carrel's machinery, he offered to build new equipment for the scientist. Eventually they built the first perfusion pump, an invention instrumental to the development of organ transplantation and open heart surgery. Lindbergh considered Carrel his closest friend, and said he would preserve and promote Carrel's ...
A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
Ex vivo lung perfusion, EVLP, is a form of machine perfusion aimed at sustaining the active aerobic cellular metabolism of donor lungs outside the donor's body prior to lung transplantation. This medical preservation technique typically occurs within a specialised machine engineered to mimic the conditions of the natural circulatory system .
Machine perfusion (MP) is an artificial perfusion technique often used for organ preservation to help facilitate organ transplantation.MP works by continuously pumping a specialized solution through donor organs, mimicking the body's natural blood flow while actively controlling temperature, oxygen levels, chemical composition, and mechanical stress within the organ.
The user interface of pumps usually requests details on the type of infusion from the technician or nurse that sets them up: . Continuous infusion usually consists of small pulses of infusion, usually between 500 nanoliters and 10 milliliters, depending on the pump's design, with the rate of these pulses depending on the programmed infusion speed.
Mousetrap, mouse, bait (chocolate) Wood mouse is captured with cage snap case An early patented mousetrap is a live capture device patented in 1870 by W K Bachman of South Carolina. [ 11 ] These traps have the advantage of allowing the mouse to be released into the wild, or the disadvantage of having to personally kill the captured animal if ...
In the rat bait pellets, mouse bait pellets, place packs, and wedge baits, the active ingredient was brodifacoum, typically at 0.005% concentration. [21] In contrast, earlier d-CON products that used warfarin had 0.5% concentration. [5] In the refillable and disposable bait stations, the active ingredient was diphacinone. [22]
