The invention provides a medical pressure extension tube with a one-way valve. The medical pressure extension tube comprises a first tube body, and one end of the first tube body is communicated with a filter cavity; the one-way valve seat is arranged on the pressure extension pipe, and the sealing groove and the sealing block are arranged in the one-way valve seat, so that the pressure extension pipe has the purpose of sealing a passage, the condition of backflow caused by conveyed liquid is prevented, and the pressure extension pipe is matched with an adjusting shaft arranged in the adjusting valve and is used through a flow baffle block; when the position of the adjusting shaft is adjusted, the flow stopping block can adjust the size of a liquid flowing channel, the filtering grating is installed in the filtering hopper, bubbles in flowing liquid can be filtered for the first time, secondary crushing work on the bubbles in the liquid is achieved through puncturing spikes and a filtering net, and the filter
