Description

Technical Field

[0001] The utility model belongs to the technical field of transrectal perfusion ultrasound imaging, and more specifically, relates to a transrectal perfusion ultrasound imaging device. Background Art

[0002] Transrectal ultrasound imaging is a medical diagnostic device used to evaluate the pathology and function of the rectum and surrounding tissues. It combines ultrasound imaging with contrast agent technology to improve image clarity and accuracy.

[0003] Patent application number CN202023196653.1 discloses a transrectal ultrasound angiography device, which solves the problem that there is no device on the market that can automatically stir and measure the temperature of the intestinal contrast agent. In addition, medical staff need to use 90-100℃ boiling water to brew the contrast agent, stir it continuously, and then inject the contrast agent into the patient's intestine after the contrast agent brewing liquid cools to 30-50℃. In actual use, this method is cumbersome, time-consuming and labor-intensive, and cannot accurately control the temperature of the contrast agent. At the same time, the rate of injection of the contrast agent into the patient's intestine is also very slow. The device includes a stirring drum with a solution cavity formed therein; a magnetic stirring device provided on the stirring drum; a contrast agent inlet tube connected to the solution cavity, the contrast agent inlet tube being provided with a balloon; a pressurizing tube connected to the solution cavity; and a temperature sensor provided on the stirring drum. During use, after the contrast agent and water are added to the mixing drum, they are continuously stirred by a magnetic stirring device, while a temperature sensor continuously monitors the temperature of the liquid in the mixing drum. When the temperature is appropriate, the contrast agent is infused into the patient's intestines through the contrast agent inlet tube. The pressurized tube increases the air pressure in the mixing drum, thereby accelerating the rate at which the contrast agent enters the patient's intestines. However, in the above-mentioned technical solution, part of the balloon moves toward the anus, resulting in incomplete blockage of the anus, which can cause contrast agent to leak out and affect the contrast detection data.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a transrectal perfusion ultrasound imaging device is provided to achieve a purpose with greater practical value. Utility Model Content
