The actual application of this utility model bed board:
In the CT Room, bed board 1 is placed on the examinating couch of CT machine, utilizes the laser calibration device then, by the graduation mark that 1 four sides of bed board are provided with, the position of proofreading and correct bed board is then with bed board 1 and examinating couch relative fixed.
Place the medicated pillow of patient's special use in the square opening 10 of bed board 1, this patient lies or crouches and is placed on the medicated pillow on bed board 1 and with head.Pass through CT scan, determine the definite position of patient's tumor focus, at this moment, the thermoplastic plate made from the macromolecule thermoplastic material, by patient's tumor focus region of living in, make the phantom of the corresponding body part shape of this patient's special use, and on phantom, make and the corresponding position mark in tumor focus position.
Radiotherapy is indoor, will be positioned on the therapeutic bed with the identical bed board 1 that CT Room uses, and utilizes the laser calibration device, and by the graduation mark that 1 four sides of bed board are provided with, the position of proofreading and correct bed board 1 is then with bed board 1 and therapeutic bed relative fixed.
In the square opening 10 of bed board 1, place the medicated pillow of above-mentioned patient's special use.Patient adopts and the interior identical posture of the CT Room upper bed board 1 of lying or crouch, and head is placed on the medicated pillow.
This patient's who makes with CT Room special-purpose phantom makes patient and bed board 1 fixing.The labelling of making on the mobile therapeutic bed, the cross point that two bundles that the laser calibration device is sent are crossed as " ten " font laser rays and phantom overlaps, thereby calibrates the relative position of focus and head, begins radiotherapy.
Tumor focus is the patient of head, the dowel hole that is provided with on the head mould of making to measure is penetrated alignment pin A 2 and alignment pin B 7 location head moulds respectively, four screws that nylon is made are connected with bed board 1 by four screws around the square opening 10 respectively, be with a macromolecular material on each screw accordingly and make pressing plate, push down the side of head mould with pressing plate, tighten screw, head mould is fixed, thereby patient's head is fixed.
Tumor focus is the patient of neck and shoulder part, and the dual-side with the neck and shoulder part phantom of making to measure snaps in respectively in bar-shaped trough A9 and the bar-shaped trough B11, again lucite is made "
" the shape voussoir snaps in bar-shaped trough, and the neck and shoulder part phantom is fixedlyed connected with bed board 1, patient is fixed.
Tumor focus is the patient of chest, abdominal part or shank, with the dual-side of chest phantom, abdominal part phantom or the shank phantom of making to measure, snaps in different bar-shaped troughs respectively according to patient's build.
The patient of build slight of stature snaps in bar-shaped trough D13 and bar-shaped trough G16 respectively with the dual-side of its chest phantom, abdominal part phantom or shank phantom, again lucite is made "
" the shape voussoir snaps in bar-shaped trough, and chest phantom, abdominal part phantom or shank are fixedlyed connected with bed board 1, patient is fixed.
The patient that build is more fat snaps in bar-shaped trough C 12 and bar-shaped trough H 17 respectively with the dual-side of its chest phantom, abdominal part phantom or shank phantom, again lucite is made "
" the shape voussoir snaps in bar-shaped trough, and chest phantom, abdominal part phantom or shank phantom are fixedlyed connected with bed board 1, patient is fixed.
For the patient of some behavior off one's feet, during treatment, need its two lower limb is fixed respectively, again its whole body is fixed, to prevent occurring accident in the radiotherapy process.At this moment; with head mould its head is fixed, its trunk is fixed, the dual-side of a shank phantom is snapped in bar-shaped trough E14 and bar-shaped trough D 13 respectively with chest phantom or abdominal part phantom; perhaps snap in bar-shaped trough E14 and bar-shaped trough C 12, then lucite is made "
" the shape voussoir snaps in corresponding bar-shaped trough, and patient's one leg is fixed, and the dual-side of another shank phantom is snapped in bar-shaped trough F15 and bar-shaped trough G 16 respectively, perhaps snaps in bar-shaped trough F15 and bar-shaped trough H 17, then lucite is made "
" the shape voussoir snaps in corresponding bar-shaped trough, patient's one leg is in addition fixed, thereby patient's whole body is fixed on the bed board 1.
Some especial patient needs to use vacuum pad.During this patient radiotherapy for the first time, the alignment pin that nylon is made inserts dowel hole A3, dowel hole B4, dowel hole C5 and the dowel hole D6 that is provided with on the bed board 1 respectively, place a vacuum pad then on the bed board 1, patient lies on this vacuum pad, by the laser calibration device, the head of radiotherapy machine is aimed at the patient's tumor focus, at this moment, begun the vacuum pad evacuation.
Took out above the vacuum pad of vacuum, formed the appearance profile of human body, below this vacuum pad, formed four corresponding grooves corresponding to the position of four alignment pins.
When repeating radiotherapy, this vacuum pad is aimed at and placed to the alignment pin of setting on the groove below the above-mentioned vacuum pad of taking out vacuum and the bed board 1, in patient lies this profile above vacuum pad then, make patient be in a fixed position with respect to bed board 1.
Afterwards, utilize the laser calibration device, the labelling on the phantom of patient's use is overlapped with " ten " font cross point of laser beam, be about to tumor focus and place accurately under the head of radiotherapy machine.
This utility model bed board; by the position of laser calibration device correction bed board 1 with therapeutic bed; with both position relative fixed; by phantom or the vacuum pad of taking out vacuum patient's position and the relative position between the bed board 1 are fixed then; repeat in the radiotherapy process; the each all definite positions on bed board 1 of patient; utilize the laser calibration device again; the labelling of the tumor focus position of making on the calibration phantom; thereby quickly and accurately patient's focus is aimed at the head of radiotherapy machine, carry out radiotherapy.Bed board 1 in use need not combination, dismounting and resetting, does not also need to change the bed board that is suitable for this patient's use according to different patients, reduced unnecessary link, for radiotherapy provides great convenience, alleviated medical and technical staff's labor intensity simultaneously, improved work efficiency.
