High-precision constant-temperature perfusion instrument for isolated organs

Abstract

The invention discloses a high-precision constant-temperature perfusion instrument for isolated organs. The high-precision constant-temperature perfusion instrument comprises an organ solution perfusion module, a state monitoring module and a GPS positioning module. The organ solution perfusion module comprises: a control unit; a fresh liquid storage case, an artificial lung filtering container, a first peristaltic pump, an organ accommodating case, a pH meter container, a second peristaltic pump and a used liquid storage case which are communicated in sequence; and a temperature sensor acquisition module, an ultrasonic measurement module, a display output module and a stepping motor which are electrically connected with the control unit; wherein the stepping motor is in transmission connection with the first peristaltic pump and the second peristaltic pump, the temperature sensor acquisition module is arranged in the organ accommodating case, measured temperature information is used for acoustic velocity temperature compensation, and the ultrasonic measurement module is used for measuring the flow velocity of a solution in a catheter. The high-precision constant-temperature perfusion instrument can monitor other physiological parameters of the organs and accurately control temperature and a perfusion speed; and due to introduction of a GPS positioning function, accurate conveying of the isolated organs is facilitated, an optimal path may be selected, and conveying time can be saved.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a high-precision constant temperature perfusion instrument for isolated organs. Background technique [0002] With the advancement of surgical technology and the advent of new immunosuppressants, organ transplantation has been vigorously developed as the only effective treatment for end-stage organ diseases. On the whole, maintaining the vitality of the graft during organ preservation is the key to the success of organ transplantation. Organ preservation has made a significant contribution to organ transplantation. Although some new organ preservation techniques, such as mechanical continuous perfusion preservation and normal temperature preservation, have begun to be applied clinically, pure low temperature preservation is still the first choice of major organ transplantation centers. [0003] Although the emergence of organ transplantation surgery has made it possible to compl...

Problems solved by technology

On the other hand, traditional cryopreservation (mixture of ice and water) is destructive to isolated organs, and the nutrient consumption of static storage can easily inactivate organs. Therefore, how to achieve high-precision constant temperature control is currently the most important aspect of perfusion preservation of isolated organs. One of the pressing problems facing the instrument
