The utility model relates to an inflating device for fixed head magnetic resonance examination, the pad is composed of a connecting plate plate plate, shoulder and back his head round and oval of them constitute a whole; the head airbag galeated, extending to the frontal part of the head airbag, airbag and human body back contact part of local adhesion; the inflatable part with an elliptical hole in both sides of the ear, two cheeks at the contact with the human body is pasted with linen bag; lower jaw extends along the facial contour; the side of the air bag at the top of the fixed inflatable inflatable tube, one end of the tube and the air bag charging port and the other end with adhesion plug; his head plate and the airbag brain part together with the air after the outer wall of the inner wall of coil and magnetic resonance scanner head tightly, the head wall and the air tight fitting stable patients. The advantages are: simple structure, easy to use, easy to carry and store. Because the patient's head is completely fixed, the accuracy and correctness of the medical image is high, and the work efficiency is high.

核磁共振頭部檢查用的充氣固定裝置
本技術(shù)涉及一種固定裝置,特別是涉及一種結(jié)構(gòu)簡(jiǎn)單、定位準(zhǔn)確、患者舒服的核磁共振頭部檢查用的充氣固定裝置。
技術(shù)介紹
眾所周知,隨著年齡的增長(zhǎng),人類腦血管結(jié)構(gòu)和功能逐漸退化,腦血管病變?cè)谥欣夏昊颊叩陌l(fā)病率隨之增高,而出現(xiàn)不同的癥狀和體征,治療不及時(shí)會(huì)使患者病灶造成不可逆的改變,早期及時(shí)診斷治療會(huì)降低患者致殘率,提高患者的生存質(zhì)量;目前,多采用核磁共振成像技術(shù)對(duì)腦血管病變進(jìn)行早期診斷;然而,核磁共振成像對(duì)運(yùn)動(dòng)的敏感性較高,哪怕出現(xiàn)輕微運(yùn)動(dòng)也會(huì)引起圖像模糊,產(chǎn)生偽影或重疊影像;尤其對(duì)于意識(shí)喪失或病情危重躁動(dòng)患者,很難使其頭部保持長(zhǎng)時(shí)間的靜止?fàn)顟B(tài),又因患者頭顱與核磁共振掃描儀線圈中間存在一定間隙,故在核磁共振檢查過(guò)程中,患者的自主性和生理性運(yùn)動(dòng)常常難以避免,它將影響數(shù)據(jù)的采集過(guò)程,破壞圖像的輪廓和細(xì)節(jié),造成醫(yī)學(xué)圖像的模糊,而干擾正確診斷;此時(shí),只能重復(fù)掃描程序,這就延長(zhǎng)了掃描時(shí)間,增加了患者在檢查過(guò)程中因不可預(yù)料的因素造成的危險(xiǎn)性;由于核磁共振檢查時(shí)禁止攜帶任何含有金屬成分如鐵、鋼等物品,使得頭部固定裝置的使用受到限制;目前,采用在核磁共振接收器線圈與患者頭顱兩頰的中間處填充非金屬物的固定方法,極不安全很可能碰到頸動(dòng)脈,另外,存在對(duì)患者造成傷害的隱患。
