Water Chiller Chemotherapy

RIGID Mini Water Chiller is a device used in clinical settings to provide cooling to a patient’s body before or after surgery. The chiller works by using a miniature dc compressor to circulate chilled water through a closed-loop system. Before surgery, the chiller is typically used to cool the patient’s body temperature in order to reduce the risk of bleeding during the procedure. This is achieved by circulating the chilled water through a special blanket or pad that is placed on the patient’s body. After surgery, the chiller can be used to help reduce pain and swelling in the affected area. This is achieved by circulating the chilled water through a specially designed hose and cuff. No need for ice!  The mini chiller itself is typically a small, portable unit that can be easily integrated into medical devices, so it can be moved from room to room or from one patient to another.

Overall, the mini water chiller is the best choice for Clinic Devices, providing temperature-controlled cooling to reduce pain, swelling, and bruising following surgery or injury. It helps to improve patient outcomes and speed up the recovery process after surgery.
