TyTek Medical's disposable portable suction unit with its resilient silicone bulb performs reliably in even the harshest climates without loss of suction. The TVAC Manual Suction Unit comes in a field friendly compact package, just pull out the built-in tube and start sucking. No bulky cartridges or brittle parts to break. After use, simply place the entire TVAC Manual Suction Unit back inside its packaging, seal, expose the biohazard label on the package and dispose appropriately. This entirely removes the possibility of cross contamination. TVAC delivers 100% of the suction -- 100% of the time.
