Problems solved by technology

[0004] Although the existing sound insulation device can play a certain sound insulation effect, the noise can still enter the sound insulation device along the unclosed position, therefore, the sound insulation effect of the existing sound insulation device is not good
Moreover, during the MRI examination, the doctor needs to communicate with the pregnant woman from time to time to guide the pregnant woman to perform the examination in the correct way. Therefore, the pregnant woman needs to repeatedly take the earplugs, which will also have a huge impact on the mood of the pregnant woman.

Embodiment 1

[0029] Embodiment one, as figure 1 The schematic diagram of the structure of the nuclear magnetic resonance detection system is shown, the detection device is provided with a nuclear magnetic resonance scanning device 1 and a sliding bed 2, and a soundproof cabin 3 made of a non-magnetic material is placed on the sliding bed 2, and the soundproof cabin 3 is provided with a single To the sound transmission channel 4, the one-way sound transmission channel 4 communicates the inside and the outside of the soundproof cabin 3, and a sound transmission direction switching device is arranged inside the channel.

[0030] Specifically, both the nuclear magnetic scanning device 1 and the sliding bed 2 are existing devices. By placing the soundproof cabin 3 on the sliding bed 2 to form a closed soundproof space, pregnant women only need to lie down in the soundproof cabin 3 during the examination. No need to wear any wearable device. The soundproof cabin 3 can isolate the noise generate...

Embodiment 2

[0053] Embodiment 2. Embodiment 2 is roughly the same as Embodiment 1. The main difference is that the sound transmission direction switching device is provided with two unidirectional sound transmission ducts 18, and the sound transmission directions of the two unidirectional sound transmission ducts 18 are opposite. , and arranged side by side in the one-way sound transmission channel 4, each one-way sound transmission pipeline 18 is provided with a soundproof door 19 at the pipe opening, and the two soundproof doors 19 are connected by an interlocking mechanism.

[0054] Specifically, the structure of the one-way sound transmission pipe 18 is the same as that of the existing one-way sound transmission channel 4, as in the above-mentioned patent "broadband one-way sound transmission channel", the opening and closing states of the two soundproof doors 19 can be switched through the interlocking mechanism , so as to switch the one-way sound transmission pipe 18 communicated wit...

Abstract

The invention discloses a nuclear magnetic resonance detection system. The nuclear magnetic resonance detection system is equipped with a nuclear magnetic scanning device and a sliding bed; a sound-proof cabin which is made of non-magnetic conductive materials is arranged on the sliding bed; a one-way sound transmission channel is arranged in the sound-proof cabin and communicates with the insideand the outside of the sound-proof cabin; and a sound transmission direction switching device is arranged in the channel. Noise which occurs during checking is isolated through the sound-proof cabin,so that embryos and pregnant women can be prevented from noise influence; and the pregnant women who stay in the sound-proof cabin can contact doctors through the one-way sound transmission channel.

Description

technical field [0001] The invention relates to the field of measurements for diagnostic purposes, in particular to nuclear magnetic resonance measurements. Background technique [0002] Every pregnant woman undergoes multiple ultrasound examinations during pregnancy to determine fetal growth. Ultrasound examination is a medical imaging diagnosis technology based on ultrasound. Its main principle is to make the ultrasound probe scan the uterus of pregnant women. During the scanning process, the ultrasound probe will continuously emit ultrasound and receive the reflected ultrasound after encountering the fetus. Determine the condition of the fetus. Although ultrasonography is routine, fetal images are blurry. Therefore, MRI is often used to examine the fetus when clear images of the fetus are required. [0003] The MRI machine will generate a lot of noise when it is working. The noise will not only affect the emotions of pregnant women, but also have a certain impact on th...
