Description
【０００１】[0001]
本考案は、頭部検査の際に、被検者の頭部を載せて固定する頭部固定器に関す るものである。 The present invention relates to a head immobilizer for mounting and fixing the head of a subject during a head examination.
【０００２】[0002]
ＣＴ検査等の最中に被検者の頭部が動いたりすると、正確な検査ができなくな る。従って、特に個人差の大きい頭頸部を確実に固定する必要がある。 If the subject's head moves during a CT examination, accurate examination cannot be performed. Therefore, it is necessary to surely fix the head and neck, which has a large individual difference.
【０００３】[0003]
本考案は、上記要求を満たす頭部固定器を提供することを目的とするものであ る。 The present invention aims to provide a head immobilizer that meets the above requirements.
【０００４】[0004]
この目的を達成するために、本考案は、寝台の一端に取付角度調節可能に取り 付けられ、断面形状が略半円状になったベースシェルと、このベースシェルの内 側に装着されたエアマットと、エアマット上に被検者の頭部を載せて仰臥したと き額部を固定する額部固定手段とから構成される。さらにこの構成に、顎部を固 定する顎部固定手段を設けた構成とする。 In order to achieve this object, the present invention has a base shell attached to one end of a bed with an adjustable mounting angle and a semi-circular cross section, and an air mat mounted inside the base shell. And a forehead fixing means for fixing the forehead when the subject's head is placed on the air mat and the person is supine. Further, a jaw fixing means for fixing the jaw is provided in this configuration.
【０００５】[0005]
エアマットに適度のエアを吹き込んで膨らますと、被検者の後頭部や側頭部、 頸部にエアマットが十分密着し、上から額部を額部固定手段により頭部を確実に 固定することができる。また、被検者に対して麻酔剤を投与し、比較的長時間に わたって検査する場合は、顎部固定手段を併用することにより、確実な固定が可 能となる。 When a proper amount of air is blown into the air mat to inflate it, the air mat will come into close contact with the occipital region, temporal region, and neck of the subject, and the forehead can be securely fixed with the forehead fixing means from above. . In addition, when an anesthetic is administered to a subject and the examination is performed for a relatively long period of time, the jaw can be fixed in combination for reliable fixation.
【０００６】[0006]
【実施例】 以下、図面を参照して実施例を詳細に説明する。図１は、本考案の一実施例を 示したもので、１は樹脂成形品からなるベースシェルであり、合板あるいはメタ クリル樹脂からなる台座２をポリウレタン単泡スポンジ製マット３で覆った寝台 の一端に、取付角度θが調節可能に取り付けられている。４はベースシェル１の 内側に装着されたエアマット、５は、エアマット４上に被検者の頭部を載せて仰 臥したとき額部を固定する額部固定バンド、６は顎部を固定する顎部固定金具で ある。Embodiments Embodiments will be described in detail below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which 1 is a base shell made of a resin molded product, and a pedestal 2 made of plywood or metacryl resin is covered with a mat 3 made of polyurethane single-foam sponge. At one end, the mounting angle θ is mounted so as to be adjustable. Reference numeral 4 denotes an air mat attached to the inside of the base shell 1. Reference numeral 5 denotes a forehead fixing band that fixes the forehead when the head of the subject is placed on the air mat 4 and supine, and 6 fixes the jaw. It is a jaw fixing bracket.
【０００７】 図２は、本実施例の頭部固定器の側面図、図３は、図２のＡ矢視図である。ベ ースシェル１は、台座２の一端に設けた軸11に基部１aが回動自在に支持され、 また基部１aの裏面に固定のアングル12に軸支されたナット13と、台座２に取り 付けたねじ14とが係合している。従って、ねじ14を回転することによりナット13 が上下し、寝台に対するベースシェル１の取付角度θを調節することができる。FIG. 2 is a side view of the head immobilizer of this embodiment, and FIG. 3 is a view taken in the direction of arrow A in FIG. The base shell 1 has a base 1a rotatably supported on a shaft 11 provided at one end of the base 2, and a nut 13 pivotally supported on an angle 12 fixed to the back surface of the base 1a and attached to the base 2. The screw 14 is engaged. Therefore, by rotating the screw 14, the nut 13 moves up and down, and the mounting angle θ of the base shell 1 with respect to the bed can be adjusted.
【０００８】 ベースシェル１の頭部載置部は、断面形状が略半円状になっており、その内側 にエアマット４が装着される。エアマット４は、図４に示したように、空気室が いくつかに仕切られており、空気吹込口４aから空気を入れると、各空気室が適 度に膨らむ。従って、吹き込む空気の量によって、個人差のある被検者の後頭部 や側頭部、頸部に十分フィットする形状になる。なお、エアマット４に設けた空 気室の仕切線は、後頭部付近においては横方向に形成してもよい。The head mounting portion of the base shell 1 has a substantially semicircular cross section, and the air mat 4 is mounted inside thereof. As shown in FIG. 4, the air mat 4 is divided into several air chambers, and when air is introduced from the air blowing port 4a, each air chamber expands appropriately. Therefore, depending on the amount of air blown in, the shape will be such that it fits well to the occipital region, temporal region, and neck of the subject, which varies from person to person. The partition line of the air chamber provided in the air mat 4 may be formed laterally near the back of the head.
【０００９】 額部固定バンド５は、エアマット４上に被検者の頭部を載せて仰臥したとき額 部を押え、バンドの左右内側に設けたマジックテープ15を、ベースシェル１の外 面に取り付けたマジックテープ16に止める。The forehead fixing band 5 presses the forehead when the head of the subject is placed on the air mat 4, and holds the forehead. Velcro tapes 15 provided on the left and right inner sides of the band are attached to the outer surface of the base shell 1. Stop on the attached Velcro 16.
【００１０】 顎部固定金具６は、被検者が麻酔剤を吸入した効果による顎部の落ち込みを防 止するためのもので、顎当部材17の位置を自由に調節できるようになっている。The jaw fixing member 6 is for preventing the subject from being depressed due to the effect of inhaling an anesthetic on the subject, and the position of the jaw support member 17 can be freely adjusted. .
【００１１】 なお、顎部固定金具６の代りに額部固定バンド５と同様な固定バンドを用いても よい。Instead of the jaw fixing fitting 6, a fixing band similar to the forehead fixing band 5 may be used.
【００１２】 図５は、上記構成の頭部固定器に被検者の頭部を固定した状態を示したもので ある。個人差の大きい頭頸部にエアマット４がぴったりとフィットし、上から額 部固定バンド５と顎部固定金具６で押えることによって、頭部が確実に固定され る。なお、比較的短時間の検査の場合は、顎部固定手段は使用しなくてもよい。FIG. 5 shows a state in which the head of the subject is fixed to the head fixing device having the above configuration. The air mat 4 fits snugly to the head and neck, which varies widely from person to person, and the head is securely fixed by pressing it with the forehead fixing band 5 and the jaw fixing bracket 6 from above. It should be noted that the jaw fixing means may not be used in the case of the inspection for a relatively short time.
【００１３】[0013]
