Respiratory adjustment device for magnetic resonance examination

Abstract

The invention discloses a respiratory adjustment device for magnetic resonance examination. The device comprises a lacing and a cylinder sleeve, wherein an elastic spherical bag is fixedly arranged onone side of the front of the lacing, a plurality of elastic strip bags parallel to each other are fixedly arranged on the other side of the front of the lacing, the upper portion of the cylinder sleeve is provided with an opening, the cylinder sleeve is internally provided with a piston, the outer circumference of the piston is cooperatively in contact with the inner wall of the cylinder sleeve,the piston can slide vertically along the cylinder sleeve, the bottom face of the piston is hinged to the upper end of a connecting rod, the bottom of the back face of the inner wall of the cylinder sleeve is fixedly provided with a cam provided with a power device, the front top of the cam is hinged to the lower end of the connecting rod, one side of the cylinder sleeve is fixedly connected to one end of a sleeve, and the sleeve is communicated with the inner portion of the cylinder sleeve. The respiratory adjustment device for the magnetic resonance examination has the advantages that the movement of a baffle is achieved through a mechanical structure, the installation of the power device in the sleeve is eliminated, the energy can be saved, a waterproof device can be also avoided from being installed outside the power device, the structure is more simplified, the components of the device are all made from non-magnetic materials, so that the magnetic field cannot be interfered, imaging cannot be affected, and the device is suitable for widespread use.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a breathing adjustment device for magnetic resonance examination. Background technique [0002] When MRI scans the abdomen, the patient's abdominal respiration often causes the abdominal wall to move up and down. On the MRI image, tissues such as fat and water with high signal will produce half-moon or cord-like motion artifacts with the movement of the abdominal wall. Affected. Publication No. CN104783797A describes a breathing adjustment device for magnetic resonance examination, which can enable the subject to breathe passively, and timely adjust the breathing frequency and amplitude to keep stable, eliminate breathing artifacts in MR images, and improve image clarity. Manpower is required to adjust the breathing frequency and amplitude, which is a great challenge to the physical strength of medical staff, and the consistent breathing frequency cannot be guaranteed.

Publication No. CN104783797A describes a breathing adjustment device for magnetic resonance examination, which can enable the subject to breathe passively, and timely adjust the breathing frequency and amplitude to keep stable, eliminate breathing artifacts in MR images, and improve image clarity. Manpower is required to adjust the breathing frequency and amplitude, which is a great challenge to the physical strength of medical staff, and the consistent breathing frequency cannot be guaranteed. Training is required before operation, and the use is limited; automatic breathing adjustment has also appeared in the existing structure device, but its function is single, unable to relieve the emotions of the subject, because the MRI examination takes a long time, and the subject's nerves are tense for a long time, which is not conducive to the recovery of the disease
