The disclosure herein provides system, methods, and devices for collection of fluids, for example, bodily fluid and other fluids. An aspiration and fluid collection device for collecting bodily fluid and other fluids comprises a cap which may be mounted on a compressible resilient body comprising a cavity for storage of collected bodily fluid and other fluids. The cap comprises an inlet port comprising a first one-way valve positioned to enable bodily fluid and other fluids to flow into the cavity through the inlet port, but not out of the cavity through the inlet port and an outlet port comprising a gas permeable but liquid resistant membrane positioned to enable gas to be expelled from the cavity through the outlet port, but to resist bodily fluid and other fluids being expelled from the cavity through the outlet port. The outlet port further comprises a second one-way valve positioned to enable gas to be expelled from the cavity through the outlet port, but not into the cavity through the outlet port.
