The invention relates to medical wireless WIFI transmission B-mode ultrasound equipment. The medical wireless WIFI transmission B-mode ultrasound equipment comprises a shell, a probe, a WIFI module, a built-in antenna, an antenna terminal, an FPGA chip, a receiving chip, a transmitting chip, an upper cover and a host. Due to the fact that only the transmitting chip, the receiving chip and the FPGA chip are included for simple signal processing and beam forming, the part with the large information handling capacity is transplanted to the host, more image processing is conducted through the powerful function of the host, excellent images are obtained, and then correct diagnosis of clinicians is guaranteed. Due to the fact that the data volume transmitted through WIFI is limited, signal transmission is completed through eight-channel data transmission, the patch antenna is arranged, and the transmission efficiency of the wireless WIFI is improved.
