Auxiliary device for cardiac ultrasonic examination

Abstract

The invention discloses an auxiliary device for cardiac ultrasonic examination, and effectively solves the problem that the body position is inconvenient to change during cardiac ultrasonic examination. The auxiliary device comprises a bed plate; a rectangular groove is formed in the bed plate; a fixed plate is arranged in the rectangular groove; a rotating plate is hinged in the rectangular groove; the lower end of the rotating plate is provided with an L-shaped plate; the lower end of the bed plate is provided with a U-shaped plate; a screw rod is connected in the U-shaped plate in threadedmanner; a main internal meshing gear is rotationally connected inside the U-shaped plate; the rear side of the main internal meshing gear is eccentrically hinged with the L-shaped plate through a connecting rod; the screw rod is provided with a main gear; a square groove is formed in the bed plate; a headrest is hinged in the square groove; the lower end of the bed plate is provided with a reset plate; the lower end of the headrest is connected with the reset plate through a spring; the front side and the rear side of the headrest are each provided with an inflatable fixed air bag; the two fixed air bags are connected through a connecting pipe; the left side wall of the U-shaped plate is rotationally connected with a secondary internal meshing gear; the left side of the screw rod is provided with a pinion; and the lower end of the headrest is connected with the secondary internal meshing gear through a connecting rope. The auxiliary device is simple in structure, novel in conception, convenient to use and high in usability.

Description

technical field [0001] The invention relates to the technical field of ultrasonic instruments, in particular to an auxiliary device for cardiac ultrasonic examination. Background technique [0002] Cardiac color Doppler ultrasound is the only inspection method that can dynamically display the structure of the heart cavity, heart beat and blood flow. Through color doppler ultrasound, medical staff can understand the type and degree of heart disease in patients. [0003] When performing cardiac color ultrasound examination, patients need to make different postures to cooperate with the examination. The supine or left decubitus position is required for transthoracic overtime examination, and the head is tilted back for the examination of the aortic arch through the suprasternal fossa. The patient turns the body angle by himself, or asks the medical staff to help the patient turn the body. After turning over, the body position is often not standard, and the doctor needs to repea...
