Abstract
The utility model discloses an anti-interference anti-noise headset player for a magnetic resonance imaging. The headset player comprises copper boxes, players, a connecting rod, and soft leather sponge cushions. The copper boxes comprise internal cylindrical bodies and copper box outer covers. The players are disposed in the copper boxes. The soft leather sponge cushions are used to wrap inside of the copper boxes. The connecting rod is provided with a thin copper pipe inside, and the thin copper pipe is used to shield a magnetic field of a lead connecting with a horn. Since the headset player uses the closed copper boxes, magnetic fields in the copper boxes are effectively shielded. Therefore, the headset player not only does not influence nuclear magnetic resonance signals, but also can play music independently, and a common play function is provided.
Description
Technical field
The utility model relates to anti-tampering headset, particularly the anti-tampering noise control headset of a kind of magnetic resonance examination player.
Background technology
Along with the development of society, the superconduction NMR system begins slowly to popularize, but there is a general problem in the superconduction nuclear magnetic resonance machine: large very large times than permanent magnetic resonance of noise causes the patient to stand for a long time.Method commonly used is to clog ear with earplug, but effect is not fine, still can be difficult to be subjected to; After common headset band got on, because there is metal the headset the inside, perhaps small magnet can't normal play under the highfield of nuclear-magnetism, but also can have a strong impact on the nuclear magnetic scanning signal, makes image unavailable.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the anti-tampering noise control headset of a kind of magnetic resonance examination player.
The technical scheme that solves the problems of the technologies described above is: the anti-tampering noise control headset of magnetic resonance examination player, comprise copper box, player, connecting rod and moccasin foam-rubber cushion, and described copper box comprises built-in cylindrical shell and copper box enclosing cover; Described player places described copper box inner; It is inboard that described moccasin foam-rubber cushion is used for parcel copper box; Be provided with a thin copper pipe in the described connecting rod, be used for the magnetic field that shielding connects the loudspeaker wire.
As improvement, the shell of described player is plastic raw materials.
As improvement, the inboard of described copper box is scale copper.
The beneficial effects of the utility model are: owing to adopt the copper box of sealing, effectively shield the magnetic field in the copper box, therefore, not only do not affect NMR signal, and can also independently play music, common playing function is provided.

Fig. 2 is the copper box enclosing cover figure of the anti-tampering noise control headset of magnetic resonance examination player.
Fig. 3 is the copper box front elevation of the anti-tampering noise control headset of magnetic resonance examination player.
Fig. 4 is the copper box back view of the anti-tampering noise control headset of magnetic resonance examination player.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Such as Fig. 1-shown in Figure 4, the anti-tampering noise control headset of magnetic resonance examination player comprises copper box 3, player 4, connecting rod 1 and moccasin foam-rubber cushion 2, and described copper box 3 comprises built-in cylindrical shell and copper box enclosing cover 10; Described player places described copper box inner; Described moccasin foam-rubber cushion 2 is used for parcel copper box 3 inboards; Be provided with a thin copper pipe in the described connecting rod 1, be used for the magnetic field that shielding connects the loudspeaker wire; The shell of described player 4 is plastic raw materials; The inboard of described copper box is scale copper.
As shown in Figure 3 and Figure 4, described player comprises lithium battery 8, loudspeaker 9, and circuit board is play chip, TF card slot 6 and charging jack 7; Also be provided with start/shutdown 5, last head, a rear head, broadcast/pause button on the panel of player.
In the utility model, owing to adopt the copper box of sealing, effectively shield the magnetic field in the copper box, therefore, not only do not affect NMR signal, and can also independently play music, common playing function is provided.
