Description

  The present invention relates to an X-ray imaging assisting tool, and more particularly to an X-ray imaging assisting tool that assists in imaging of a stomach region by pressing against an abdomen of a subject.

Currently, X-ray imaging of the human stomach is usually performed by the standard imaging method recommended by the NPO Japan Gastrointestinal Cancer Screening Accuracy Control and Evaluation Organization, or by a new imaging method based on guidelines published by the Japanese Cancer Screening Society. Has been done.
These radiographs are usually placed in the prone position abdominal compression body that presses against the pigtail (seasonal assistant) of the subject who has been prone on the examination table, presses the abdomen, extends the stomach region, and expands the drawing range. Hereinafter, the abdominal compression body is abbreviated), for example, using a compression pillow or a compression futon.
Of these compression maculas and compression futons, the compression macula usually consists of a bath towel, and this bath towel has a small number of turns in the lean type according to the body type of the subject, for example, the body type such as lean or obese. The obese type uses multiple rolls, with a size (thickness) and shape adjusted, and the compression futon is usually made of a small zabuton. And it is selected and used according to the body shape.

  For such bath towels and small Zabtons, change the thickness and shape of bath towels according to the patient's body shape, and select different sizes and thicknesses for small Zabtons. Therefore, a more devised abdominal compression body has been proposed because it is troublesome to select ones with different thicknesses and shapes or different sizes or thicknesses.

  For example, Patent Document 1 below proposes an X-ray imaging aid that provides compression means including two balloons and performs X-ray imaging of the stomach.

  As shown in FIG. 11, this X-ray imaging assisting tool is a subject who is prone on the bed when performing X-ray imaging of the stomach with an X-ray imaging apparatus having a tiltable bed. An x-ray imaging assisting tool that is disposed in the epigastric region and used for compressing the abdomen, and includes a compression means 40 that expands when fluid is supplied, and a fluid feed that supplies fluid to the compression means. The compression means 40 includes two balloons 41 and 41 that are inflated by the inflow of fluid, and a restraining body 43 that prohibits the balloons from expanding beyond a predetermined volume. After the volume reaches the volume, the fluid can flow into the balloon to adjust the hardness of the compression means, and the compression means is a state in which a plurality of balloons on which the restraining body 43 is attached are stacked in the balloon inflating direction. It is equipped with an integration means that integrates The conjugated unit, has a structure in which a package 42 which encloses the balloon plurality superimposed state.

According to this auxiliary tool, the compression means for compressing the abdomen of the subject includes a balloon that is inflated by the inflow of fluid, and a restraining body that prohibits the balloon from expanding beyond a predetermined volume. Since the hardness of the compression means can be adjusted by allowing fluid to flow into the balloon even after the predetermined volume is reached, deformation of the compression means can be made difficult to occur, and the compression state of the abdomen by the compression means changes Can be suppressed.
In particular, even when the tilting state of the bed of the X-ray imaging apparatus is changed, the pressure means is hardly deformed, so that the pressure state of the abdomen by the pressure means does not change, and the subject is aware of maintaining the posture. There is no need, and the burden on the subject can be greatly reduced.

  Similar X-ray imaging aids are also described in Patent Documents 2 to 5 below.

Japanese Patent No. 5936050 Japanese Patent Laying-Open No. 2015-173895 JP-A-8-150139 Japanese Patent No. 3755531 Japanese Utility Model Publication No. 5-30436

  However, among the above-mentioned abdominal compression bodies, the compression pillow made of bath towels is crafted into a predetermined size and shape by crafting an irregular bath towel into a round shape, etc., in accordance with the body shape of the subject. Since it must be adjusted, it is difficult to handle, requires skill, and is a difficult task for beginners, and its quality is reflected in the test results, and if it is not possible, accurate test results may not be obtained . On the other hand, the rolled towel is not elastic or springy, and if the hard part hits the abdomen strongly, it will cause pain to the subject. This may cause medical accidents.

  In addition, the compression futon made of small Zabuton must be matched to the body shape, and each time it has to be selected, the number increases. On the other hand, the elasticity or spring force is insufficient, and the stomach part is desired. There is a risk that it will not be possible to progress to the range.

  Furthermore, the X-ray imaging auxiliary tool described in Patent Document 1 prohibits compression means comprising two balloons, fluid supply means for supplying fluid to the means, and expansion of the balloon volume beyond a predetermined level. It is comprised from the restraint body, the integrated means integrated in the state where several balloons were piled up in the expansion | swelling direction of each balloon, and the package body which contains the balloon of the several piled-up state. For this reason, there are many means and objects such as compression means and restraints, and the auxiliary tools are expensive, and their operations are extremely troublesome and cannot be handled by beginners. In addition, the fluid (air) adjustment to the balloon (balloon) must be adjusted each time according to the subject, so it takes time and the examination efficiency deteriorates. This is an issue in cases such as group screening.

  In addition, the X-ray imaging aids described in other Patent Documents 2 to 5 have substantially the same configuration, and thus have similar problems.

  By the way, the stomach of a person changes in shape or deformation depending on sex, body shape, organs around the stomach, etc., and varies depending on the individual, so to speak, it is different from 10 people to 10 different colors. For example, by obesity type, the obese type is generally cow horn-shaped, the standard type is cocoon-like, or the heel-height type is elongate, while the stomach is also deformed. Deformation, extra-stomach compression, wall irregularity, wall hardening, gastric angle is transformed into U-shaped deformation, crab-shaped deformation, disappearance of gastric angle, right angle, straightening, sharpening, etc. with respect to normal stomach.

  Furthermore, in the X-ray imaging apparatus, the examination table is tiltable, and the position of barium (carbon dioxide) in the stomach is adjusted by appropriately tilting the subject who is prone to the examination table, Accurate positioning is required between the stomach shape of the subject and the X-ray imaging aid.

  When such an X-ray imaging aid is used, as described above, the stomach of a person changes in shape or deformation depending on the sex, body type, surrounding organs, etc., and varies depending on the person. It is another thing, and it requires accurate positioning between the stomach part of the subject who is prone and the assisting device with barium (carbon dioxide). In addition, depending on the type of assisting device used and how it is pressed or placed on the abdomen, the compression or extension state of the stomach region changes. Cannot shoot.

  However, the conventional assistive devices do not know where the stomach part corresponds to the stomach shape, and most of them are based on the experience or intuition of clinical radiologists (hereinafter referred to as radiologists). I had to rely on it.

Then, hospitals and other facilities are equipped with different types of X-ray imaging aids, which are selected and operated by the radiologist, but the proficiency level of the radiologist, that is, the experienced radiologist, the mid-career radiologist, and the initial radiation. Depending on the engineer, the test results will differ, and as a result, there will be a disparity between facilities and an inspection disparity between radiologists. In addition, if a reexamination is necessary at a later date, X-ray imaging film will be used to check what X-ray imaging aids are used in the previous imaging and how they are pressed against the abdomen. I can't do that because there is no history. For this reason, even if the selection and use method of the X-ray imaging auxiliary tool is inappropriate, the history review cannot be performed, the opportunity for improvement is lost, and the same may be repeated in subsequent imaging.
Under these circumstances, academic societies and others have published standard shooting guidelines and attempted to correct the inspection gap, but these inspection gaps have not yet been resolved.

  Therefore, the present inventors have been engaged in X-ray imaging for over 30 years so far in order to solve this problem and respond to the request because the prior art has the above-mentioned problems and various demands. The abdominal compression bodies constituting the X-ray imaging auxiliary tool are composed of a small number and simple shapes, and by using them alone or in combination, a gastric shape that varies depending on the subject, for example, a rod-shaped stomach It can be used for almost all stomach shapes such as the transverse stomach (cow horn stomach), the pituitary stomach, and the stomach stomach, and by attaching X-ray markers to these abdominal compression bodies, they can be monitored at the time of photographing. The X-ray marker makes it possible to grasp the state of use at the time of the examination at a later date, and it can be used for re-examination or verification. As a result, the examination disparity between facilities and radiologists is eliminated and accurate Conceive that a shadow, which has led to the completion of the present invention.

  The present invention has been made to solve the above-described problems of the prior art and to meet the above-mentioned various demands.

  Hereinafter, the detailed configuration of the X-ray imaging aid and other features and effects will be described.

An abdominal compression body will be described with reference to FIGS. 1A and 2. 1 shows an X-ray imaging auxiliary tool according to Embodiment 1 of the present invention, FIG. 1A is a perspective view of a prone position abdominal compression body, FIG. 1B is a perspective view of an auxiliary spring body, and FIG. 1C is a cover body. FIG. 2 is a perspective view, FIG. 2 shows the prone position abdominal compression body of FIG. 1A, FIG. 2A is a side view, and FIG. 2B is a top view.
As shown in FIG. 1A and FIG. 2A, the abdomen compression body 11 is a block body of a predetermined shape having a front and back area and thickness of a predetermined size, for example, a body cushion portion 12 having a disk shape or a small Zabuton shape, And a mountain-shaped spring protrusion 13 having a predetermined height protruding from the front or back surface of the main body cushion portion 12, in this embodiment, the substantially central portion of the back surface (the lower surface in FIG. 1). It is made of a sponge material made of a synthetic resin having excellent properties, cushioning properties and shock absorption. In addition, although a block body is not limited to the thing of a specific shape, Arbitrary things may be sufficient, Hereinafter, it demonstrates with a disk-shaped thing.

As shown in FIG. 2A, the main body cushion portion 12 is a disk-shaped block body composed of upper and lower flat surfaces 12a and 12b having a predetermined size and a peripheral surface 12c having a predetermined height, and the upper flat surface 12a is formed on the abdomen. The pressing surface or the mounting surface of the auxiliary spring body 15 is provided, and the peripheral side surface 12 c is curved and a part of the peripheral surface 12 c is an attachment surface of the X-ray marker 14. Incidentally, the upper flat surface 12a is to dispose desorption member an auxiliary spring member 14 at a substantially central portion 12 ₁ can be detachably mounted (not shown) preferred.

Further, the spring protrusion 13 is formed of a mountain block protruding at a predetermined height from the substantially central portion of the back surface 12b (the lower surface of FIG. 1) of the main body cushion portion 12.
The chevron spring protrusion 13 is composed of a chevron block in which a large block 13a and a small block 13b are stacked in two stages, and is formed of a sponge material integrated with the main body cushion 12. Yes.

  The size of the abdomen compression body 11 is in the main body cushion portion 12, the diameter D1 of the upper flat surface 12a is 200 mm, the thickness H1 is 50 mm, the height H2 of the spring projection 13 is 50 mm, and the spring projection 13 The large block 13a has a bottom surface diameter D2 of 100 mm and a height of 25 mm, and the small block block 13b has a bottom surface diameter D3 of 50 mm and a height H3 of 25 mm. In addition, this dimension is an example, Comprising: It is not limited to these.

  The abdomen compression body 11 includes a main body cushion part 12 and a spring projection part 13, which are formed of a sponge material and have a predetermined thickness and height, respectively, so that the abdomen compression body 11 is pressed against the abdomen. At the same time, the main body cushion portion 12 becomes a cushion and is elastically compressed, and at the same time, the spring protrusion 13 is similarly compressed and a repulsive force is exerted, so that the stomach region can be stretched by appropriate elasticity and spring force. it can. Of course, there is no pain like a compression mackerel made of a conventional bath towel.

  The main body cushion portion 12 has an X-ray marker 14 attached to a part of its side peripheral surface 12c.

The X-ray marker will be described with reference to FIG. 2C. FIG. 2C is a side view of the X-ray marker.
The X-ray marker 14 is made of a plate-like body having a predetermined thickness W and length H, and is formed of an X-ray semi-absorbing material or an absorbing material. The thickness d is 2 mm, the length h is 20 mm, and the width w is 10 mm, for example.

As for the X-ray semi-absorbing material and the absorbing material, the larger the element symbol, the lower the X-ray transmission, and the lowest transmission is lead (blocks X-rays), and then silver, iron, and titanium. Among them, titanium has a high X-ray transmittance. In this embodiment, aluminum is used.
The X-ray marker 14 can monitor the abdominal compression body 11 at the time of examination, and is also a scaler. In other words, the X-ray marker can measure the size of advanced gastric cancer, and the X-ray examination result can be used as a verification example at a later date. This verification example can also improve future examination methods.

The length as the scaler is preferably in the range of 10 mm to 20 mm. If gastric cancer is found by examination, it is said that if the length of the cancer tissue is about 10 mm, the risk of life is low and can be almost cured, and if it is 20 mm, the risk of life increases to 70-80%. . Since the X-ray marker and the cancer tissue are copied from the X-photo, the cancer risk can be easily determined from the comparison between the two.
The X-ray marker 14 is attached to a part of the side peripheral surface 12c of the main body cushion portion 12 by pasting or embedding. By making the X-ray marker detachable, the radiologist can arbitrarily select it.
The X-ray marker 14 is not limited to a plate-like body, and may have another shape such as a rod-like body. Further, it may be bent not in a straight line, but in a "<" shape, for example.

The auxiliary spring body will be described with reference to FIGS. 1B and 3. 3 shows the auxiliary spring body of FIG. 1A, FIG. 3A is a front view, FIG. 3B is a side view, FIG. 3C is a bottom view, and FIG. 3D is a perspective view of a usage example.
The auxiliary spring body 15 has rectangular upper and lower surfaces 15a and 15b and side peripheral surfaces 15c to 15f having a predetermined size, is formed of a rectangular columnar block body having a predetermined height, and is formed of a sponge material. The dimensions of the auxiliary spring body 15 are, for example, a horizontal width W1 of 100 mm, a length L of 200 mm, and a vertical width W2 of 60 mm.

As shown in FIG. 3D, the auxiliary spring body 15 is used by being folded in half at a substantially central portion and mounted on the surface 12 a of the main body cushion portion 12 constituting the abdomen compression body 11. By folding in half, the auxiliary spring body is curved in a substantially “<” shape and a relatively strong spring force is generated, which is added to the spring force of the abdomen compression body 11, strengthening the pressing to the abdomen, and making the stomach part more Can be effectively extended. The abdomen compression body 11 and the auxiliary spring body cause a problem that the conventional pressure compression mackerel (makura with a rolled bath towel) holds even if the spring force becomes stronger, and does not hurt the subject. In order to ensure the placement of the abdomen compression body 11 on the surface 12a, it is preferable to provide the placement portion 12 ₁ (see FIG. 1A) of the auxiliary spring body 15.

The X imaging assisting tool 10 is used by covering the abdominal compression body 11 alone or the abdominal compression body 11 and the auxiliary spring body 15 with a cover body 16 at the time of inspection. The cover body, as shown in FIG. 1C, includes a housing portion 16a with an opening 16 ₁ and the cord 16b closes the opening is attached, has to be sealed. The cover body 16 is made of a thin rubber material. The material is not limited to the rubber material, and may be made of other materials. For example, if it is made of a non-slip material, it is possible to prevent slipping during inspection.

An X-ray imaging method using the X-ray imaging aid of Embodiment 1 will be described with reference to FIGS. 4 shows an X-ray imaging method for each stomach shape using the X-ray imaging assisting tool of Embodiment 1, FIG. 4A is a schematic view of a stomach stomach / pituitary stomach imaging, and FIG. 4B is a slightly lateral gastroscopy image. FIG. 5 is a schematic diagram showing another gastric X-ray imaging method using an X-ray imaging aid, FIG. 5A is a schematic diagram of transverse gastroscopy, and FIG.
4 and 5 show the position of the subject's head, abdominal wall, diaphragm, and xiphoid process (pigeon) and the X-ray imaging aid used when the subject is placed prone on the examination table. Showing the relationship.
The term “prone position” means a state in which the subject's face is laid face down on its face in a natural shape. Further, the X-ray imaging assisting tool to be used differs depending on the stomach shape. In the case of the stomach shape of FIG. 4, the abdominal compression body is used alone, and in the case of the stomach shape of FIG. 5, the combination of the abdominal compression body and the auxiliary spring body is used. It has become.

(A) Shooting of stomata / pituitary stomach When the subject's stomach is stomata / pituitary, the abdominal compression body 11 is used alone as an X-ray imaging aid 10 and monitored with an X-ray marker. The position is adjusted while accurately positioning and X-ray imaging is performed.
That is, the rod-shaped stomach is a stomach that is bent like a fishing hook or a saddle, and is a stomach part that is difficult to photograph the stomach body part, the vestibule part, and the pylorus part, but as shown in FIG. By pressing the compression body 11 against the subject's pigeon tail, the U, M, and L portions of the stomach stomach are expanded and expanded, and the anterior stomach wall is also expanded and expanded in the U, M, and L portions of the stomach stomach. Because of the widening, accurate X-ray imaging can be performed.

  The drooping stomach is a stomach that is drooping and has a gastric cut at the corner of the stomach that extends beyond the iliac line and covers the pelvis. This stomach is a stomach that is difficult to photograph the stomach, vestibule, and pylorus. Although it is a part, by moving the abdominal compression body 11 to the position of the dotted line in FIG. 4A, the U, M, and L portions of the hypogastric stomach are expanded and enlarged, and the rendering range is widened. X-ray photography is possible.

(B) Slightly transverse stomach photography The mild transverse stomach is the stomach, vestibule, and pylorus. The stomach is further shortened and tilted to the side and rotated slightly to the side of the head. Extension in the vertical direction and flattening in the horizontal direction are required.
Therefore, as shown in FIG. 4B, this slightly lateral stomach is photographed by pressing the abdominal compression body 11 against the pigeon tail of the subject in the same manner as the rodent stomach of FIG. 4A. The result will be the same as that taken from the stomach.

(C) Imaging of the lateral stomach For the lateral stomach, as shown in FIG. 5A, the auxiliary spring body 15 is folded in two and attached to the abdominal compression body 11, and the abdominal compression body 11 is attached to the pigeon tail of the subject. Press to shoot.

(D) Shooting of the stomach-like stomach The stomach-like stomach is a stomach where the ridge is swollen on the back side, and this is observed like a cloth. However, it is difficult to photograph the body of the stomach, the vestibule, and the pylorus. It is the stomach part. Therefore, as shown in FIG. 5B, the X-ray assisting tool 10 is obtained by folding the auxiliary spring body 15 on the abdomen compression body 11 and attaching the abdomen compression body 11 to the pigeon tail of the subject. .
