Manual perfusion of coupling agent is more cumbersome and troublesome, and it is difficult to empty the air bubbles in the coupling agent, which affects the clarity of the rectal cavity ultrasound examination image; In the prior art, the commonly used perfusion device is usually fixed in size, such as 80ml, 100ml, etc. Although the perfusion device of this size meets the use requirements to some extent, it also has obvious limitations. Too small size will increase the number of perfusion devices needed during examination, thereby increasing the operation complexity and time cost; and too large size will increase the difficulty of filling coupling agent into the perfusion device, affecting the operation efficiency; Most of the perfusion devices in the prior art are designed for one-time use, which not only leads to the increase of material cost, but also increases the labor and time cost. Multiple perfusion devices filled with coupling agent need to be prepared in advance for each examination and discarded after use, which undoubtedly increases the operating cost of medical institutions; In order to solve the above technical problems, the present application discloses a coupling agent quantitative positioning perfusion device for rectal cavity ultrasound examination.
