Description

Auxiliary device capable of reducing magnetic resonance noise Technical Field The utility model belongs to the technical field of medical appliances, and particularly relates to an auxiliary device capable of reducing magnetic resonance noise. Background Nuclear Magnetic Resonance (MRI) is an imaging examination method widely applied in clinic, and the MRI technique has the characteristics of no wound, no radiation, clear display to soft tissues, and the like, is widely applied in the medical field, brings positive effects to diagnosis of doctors, and has very important effects. However, during nuclear magnetic resonance examination, a loud sound is generated, and the sound volume is usually 60 to 90 db, like construction site or heavy traffic noise. Noise is mainly due to the magnetic field variations of the machine and the gradient coil operation. The length of the examination is variable, typically 15 to 30 minutes, during which the noise continues. Such noise is tolerable to most people, but may be uncomfortable for sound sensitive people, children, elderly people, and stress people. Aiming at the problems, the prior art mainly uses earplugs or earmuffs for prevention and treatment, but the earmuffs are poor in sound insulation effect and cannot well block noise, the earmuffs are easy to loose and incline in the use process, the earmuffs lose the original isolation effect after moving when the earmuffs are used, meanwhile, the prior earmuffs are difficult to realize one-key fixation and release, and the existing earmuffs lack of switching between isolation and non-isolation of sound, so that defects still exist to a certain extent. Accordingly, there is a need for a magnetic resonance noise reduction assist device that solves the above-mentioned problems. Disclosure of utility model In order to solve the technical problems, the utility model designs an auxiliary device capable of reducing magnetic resonance noise, which comprises an arc-shaped bracket, an external supporting cover and an adjusting component, wherein two ends of the arc-shaped bracket are fixedly connected with the external fixing cover, the external fixing cover is of a hollow hemispherical structure, a through hole is formed in the middle of the external fixing cover, and the adjusting component is fixedly arranged on the through hole; The adjusting component comprises a fixed cylinder, a supporting rod, a rotating head and an internal connector, wherein the fixed cylinder is fixedly arranged on the through hole, a spring is fixedly arranged in the fixed cylinder, the supporting rod is sleeved in the spring, the rear end of the supporting rod is fixedly connected with the spring, the front end of the supporting rod extends out of the fixed cylinder, a bearing joint is fixedly arranged at the rear end of the supporting rod, arc-shaped inclined grooves are symmetrically arranged on the side wall of the bearing joint, grooves are arranged between the arc-shaped inclined grooves, the internal connector is fixedly arranged in the rotating head, side slats are fixedly arranged on the outer side wall of the internal connector, and slide on the arc-shaped inclined grooves and the grooves; The front end of the support rod is detachably connected with an inner fixing component, and the inner fixing component comprises an inner fixing cover and an inner extension rod, wherein a sleeve joint is fixedly arranged at the rear end of the inner fixing cover and detachably arranged on the support rod, the inner extension rod is fixedly arranged in the inner fixing cover, and the front end of the inner extension rod is fixedly provided with a blocking head; Further, the sleeve joint is detachably arranged on the supporting rod in a threaded connection mode, is connected in an inserting mode or is connected in a magnetic attraction mode; furthermore, the support rod is made of silica gel material, and the material used for the plugging head comprises silica gel, sponge and rubber; further, a rear support is fixedly arranged on one side end wall of the arc-shaped support, the rear support is of an arc-shaped structure and is attached to a biological anatomical structure from the hindbrain to the neck of a human body, and the arc-shaped support is in telescopic connection through a fixing bolt.
