Description

  [Technical Field] The present invention relates to a pillow for medical examination used when an examinee who lies on his / her back on a couch top of a medical examination apparatus fixes his / her head.

In recent years, examination techniques such as computed tomography (CT) and nuclear magnetic resonance imaging (MRI) have been widely used in medical practice.
In general, when performing a CT examination, an MRI examination, or the like, a person to be examined sleeps on his / her back on a couch top of the examination apparatus. At this time, in order to acquire a clear image, the examinee on the top board places the head on the pillow for medical examination and fixes it.

In this specification, “medical examination apparatus used in CT examination, MRI examination, etc.” is simply referred to as “inspection apparatus” unless otherwise specified, and “medical examination used in CT examination, MRI examination, etc.” Unless otherwise specified, the “bed of the apparatus bed” is simply referred to as “top plate”.
A general medical examination pillow used by an examinee to fix a head is often an elongated rectangular parallelepiped (see, for example, Non-Patent Document 1). The horizontal width of this general inspection pillow is substantially equal to the width of the head of the subject or slightly longer than the width of the head of the subject.

In the following description, “general medical examination pillow used by the examinee to fix the head” is simply “general medical examination pillow” unless otherwise specified. I will call it.
Moreover, a medical head neck support has been proposed as a pillow for medical examination designed for a subject to fix his / her head (see Patent Document 1).

  This medical head neck support has a cervical support part formed with a convex cervical support surface for placing the patient's cervical part, and a curved part for placing the patient's occipital region continuously at the rear end of the cervical support surface A head support portion on which a posterior head support surface is formed, and a rear wall portion on which a head contact surface is formed to contact the patient's head top continuously with the rear end of the occipital support surface The cervical support surface is a three-dimensional curved surface defined by a convex curved surface in which the top is formed in the middle position in the front-rear direction, and a symmetric concave curved surface in the width direction, and the occipital support surface is In the front-rear direction, the three-dimensional curved surface is defined by a concave curved surface in which the deepest part is formed in the middle position, and in the width direction is defined by a left-right symmetric concave curved surface in which the deepest part is formed. Top The surface is a three-dimensional curved surface defined by a concave curve in the front-rear direction and a concave curved surface that is symmetric in the width direction. The center has a cut-out portion cut into a symmetrical concave curved surface whose rear end edge is the deepest part.

  The lateral width of the medical head neck support in the left-right direction is slightly shorter than the width of the head of the subject.

Amazon Japan Co., Ltd., “Kakuma Black / Vinyl (12.5 × 34.5 × 8 cm)”, [online], [Searched on December 11, 2014], Internet <URL: http: // www. amazon. co. jp / gp / product / B009RKKBOS / ref = s9_simh_bw_p201_d0_i1? pf_rd_m = AN1VRQENFRJN5 & pf_rd_s = merchandised-search-12 & pf_rd_r = 18NYK2D1CFTF4P0YG7XM & pf_rd_t = 101 & pf_rd_p = 180030509_pf = rd944509

The above-mentioned existing general medical examination pillow and medical head neck support have the following problems.
First, when a subject undergoes a CT examination or the like, he or she must take various postures on the top board according to the image to be photographed. As typical postures taken by the examinee who has slept on the top board, for example, the following two postures can be cited.

The first posture is a posture in which both arms are stretched along the body side while lying on the top on the top board. The second posture is a posture in which both arms are extended upward in the height direction while lying on the top on the top board.
In this specification, “the posture in which both arms are stretched upward in the height direction while lying on the top plate” is “the arms in the height direction upward while lying on the top plate in the height direction” It is a posture that extends to the side (that is, the head side in the height direction) and is aged, with the back of the hand facing the top plate and the elbows of both arms lightly bent outward. In this specification, “an attitude in which both arms are stretched upward in the height direction while lying on the top of the table” is simply referred to as “an both arms extended attitude” unless otherwise specified. And

  Consider a case where an examinee who puts his head on a general pillow for examination is in an arm extended posture. As described above, the width of a general inspection pillow is narrow. For this reason, the examinee cannot put his / her upper arm or forearm on a general examination pillow, and cannot put both arms on the top plate. After all, the examinee is forced to take a state where the upper arm and the forearm are suspended in the air. For this reason, it is physically burdensome for the subject to keep taking both arms extended posture while undergoing the examination.

If an examinee with both arms extended posture tries to put his / her upper arm or forearm on the top plate, the shoulder joint may be damaged. In some cases, it causes dislocation of the shoulder joint. In particular, when the examinee is an elderly person whose joint is hard or a child whose skeleton is not solid, there is a high possibility that such a shoulder joint accident will occur.
The same applies to a case where an examinee who places his / her head on a medical head neck support takes an extended posture on both arms.

  The present invention solves the above-mentioned problems, and the object of the present invention is to have an examinee sleeping on his / her back on a couch top of a medical examination apparatus so that both arms are on the upper side in the height direction. It is an object of the present invention to provide a pillow for medical examination that makes it possible to take an extended posture easily and safely, and to keep this posture easily and safely.

The present invention has the following configuration in order to solve the problem. The pillow for medical examination according to the invention of claim 1 is used by an examinee who lies on his or her back on the couch top of a medical examination apparatus and places it on the couch to fix his head. A pillow for medical examination, comprising: a head placement portion comprising a dent on which the subject places his head; and arm placement portions formed on both left and right sides of the head placement portion; Each of the arm placement portions has an inclined surface forming an upper arm placement surface and an inclined surface forming a forearm placement surface, and the forearm placement surface is continuous with the front end of the upper arm placement surface. Between the angle α ° at which the upper arm placement surface is inclined with respect to the bottom surface and the angle β ° at which the forearm placement surface is inclined with respect to the bottom surface,
55 ° ≧ α ° ≧ 35 ° (1)
40 ° ≧ β ° ≧ 20 ° (2)
α °> β ° (3)
The relationship is established.

  It is assumed that an examinee who lies on his or her back on the top plate of the bed of the inspection apparatus puts his head on the depression of the head placement portion of the pillow for medical examination, and takes both arms upright posture. At this time, the subject can place the upper arm on the upper arm placement surface and the forearm on the forearm placement surface. For this reason, it is not necessary for the examinee to keep the upper arm or the forearm in the air, and it is possible to easily keep the upper arm extended posture. In addition, because the upper arm and forearm are supported from below by the arm placement part, it is easy to prevent excessive force from being applied to the shoulder etc. due to the time signature, and it is easy to hurt the shoulder joint Can be prevented.

  According to the knowledge obtained by the inventor of the present application, if the angle α ° at which the upper arm placement surface is inclined with respect to the bottom surface of the pillow for medical examination is 55 ° ≧ α ≧ 35 °, both arms are extended. The examinee can easily put the upper arm on the upper arm placement surface, and no excessive force is applied to the shoulder. And according to the further knowledge obtained by the inventor of the present application, it is even more preferable that the angle α ° is 48 ° ≧ α ≧ 42 ° from the viewpoint of further reducing the load on the shoulder of the subject. .

  According to the knowledge obtained by the inventor of the present application, if the angle β ° at which the forearm mounting surface is inclined with respect to the bottom surface of the pillow for medical examination is 40 ° ≧ β ≧ 20 ° and α °> β °, The examinee who takes both arms extended posture can bend the elbow lightly and easily put the forearm on the forearm placement surface, and the entire arm can be supported by the arm placement section. And according to the further knowledge obtained by the inventor of the present application, the angle β ° is more preferably 33 ° ≧ β ≧ 27 ° from the viewpoint of further reducing the load on the shoulder of the subject. .

According to the calculation by the present inventor based on the Japanese physique data, the medical examination pillow preferably has the following dimensions.
That is, it is preferable for the Japanese who uses the pillow for medical examinations that the lateral width of the head placement part is 18 to 20 cm. It is preferable for the Japanese who uses the pillow for medical examinations that the height from the bottom surface of the portion of the head placement portion on which the occipital region of the subject is placed is 4 to 6 cm. It is preferable for the Japanese who use the pillow for medical examination that the lateral width of the left and right arm placement portions is 16 cm or longer. In the left and right upper arm placement surfaces, the length in the front-rear direction along the inclined surface of the upper arm placement surface is preferably 21 to 25 cm for Japanese who use a pillow for medical examination. In the left and right forearm placement surfaces, the length in the front-rear direction along the inclined surface of the forearm placement surface is preferably 22 to 26 cm for Japanese who use a pillow for medical examination. Or the length of the front-back direction along the inclined surface of a forearm mounting surface may be 26 cm or more. If the length in the front-rear direction along the inclined surface of the forearm placement surface is increased, the examinee who takes the upper arm extension posture can place the back of the hand on the forearm placement surface.

  In addition, in the pillow for medical examination, the lateral width of the head placement part, the height from the bottom surface of the head placement part where the occipital region of the subject rests, the left and right direction of each arm placement part The horizontal width, the length in the front-rear direction along the inclined surfaces of the left and right upper arm placement surfaces, and the length in the front-rear direction along the inclined surfaces of the left and right forearm placement surfaces are not limited to the above-mentioned dimensions. Of course, the dimensions can be changed according to the physique of the person to be inspected, and the dimensions do not interfere with the bore of the gantry of the inspection apparatus.

  The head mounting portion can be formed of, for example, a low resilience foam or a polymer gel. Moreover, it is also possible to form an arm mounting part with a low resilience foam, a polymer gel, etc., for example. By forming at least the head placement portion and the arm placement portion with such a material, the head placement portion is deformed according to the shape of the head of the subject, and the arm placement portion is also the arm of the subject. The subject can be deformed according to the shape, and the inspected person can easily maintain the required posture.

Furthermore, it is preferable that the material forming the head placement portion or the arm placement portion has air permeability. Since the material forming the head placement portion and the arm placement portion has air permeability, discomfort due to sweating of sweat can be prevented.
Of course, the material for forming the head placement portion and the arm placement portion is not limited to the low-rebound resilience foam or the polymer gel. You may cover a head mounting part and an arm mounting part with toweling cloth, a nonwoven fabric, etc.

The inspection pillow according to the invention of claim 2 is the inspection pillow according to claim 1, wherein the flat surface portion is provided on the rear end side of the arm placement portion, The inclined surface of the forearm placement portion is continuous.
The subject to be inspected with both arms extended can place the back of the hand on a flat surface formed continuously with the inclined surface of the forearm placement portion. Further, if necessary, equipment such as an infusion tube or a three-way stopcock can be placed on this flat portion.

  Because it is a pillow for medical examination as described above, it is easy and safe for an examinee who lies on his or her back on the couch top of a medical examination apparatus to have both arms extended upward in the height direction. This makes it possible to easily and safely maintain a posture in which both arms are extended upward in the height direction.

It is a perspective view of the pillow for medical examinations. It is a side view of the pillow for medical examinations. It is a front view of the pillow for medical examinations.

For example, d1 = 20 cm can be set according to the Japanese physique. And the height from the bottom face 19 in the front side end of the back head mounting surface 12 is h. For example, h = 5 cm can be set according to the Japanese physique and the size of the gantry bore of the inspection apparatus.
The arm placement portion 15L includes an inclined surface that forms the upper arm placement surface 16L and an inclined surface that forms the forearm placement surface 17L. The upper arm placement surface 16L and the forearm placement surface 17L are adjacent to each other, and the rear edge portion of the upper arm placement surface 16L is continuous with the front edge portion of the forearm placement surface 17L. The upper arm placement surface 16L and the forearm placement surface 17L are formed of a low-rebound elastic foam having air permeability.

  The inclined surface forming the upper arm placement surface 16L is inclined with respect to the bottom surface 19 at an angle α °. For example, α ° = 45 ° can be set according to the physique of the Japanese and the size of the bore of the gantry of the inspection apparatus. Further, the inclined surface forming the forearm placement surface 17L is inclined with respect to the bottom surface 19 at an angle β °. For example, β ° = 30 ° can be set according to the Japanese physique and the size of the gantry bore of the inspection apparatus. Expressions (1) to (3) are established between the angle α ° and the angle β °.

55 ° ≧ α ° ≧ 35 ° (1)
40 ° ≧ β ° ≧ 20 ° (2)
α °> β ° (3)

Further, when the medical examination pillow 10 is viewed from the front side, the lateral width of the upper arm placement surface 16L and the lateral width of the forearm placement surface 17L are both d2. For example, d2 = 16 cm can be set according to the Japanese physique and the size of the gantry bore of the inspection apparatus.

For example, d6 = 52 cm can be set in accordance with the Japanese physique and the size of the gantry bore of the inspection apparatus.
The above is the configuration of the medical examination pillow 10.

Next, the operation and effect of the medical examination pillow 10 will be described by taking as an example a case where the subject undergoes examinations such as CT examination and MRI examination.
The medical examination pillow 10 is placed on the top plate 32 of the bed 31 of the examination apparatus. At this time, the surface of the top plate 32 and the bottom surface 19 are parallel to each other. Then, the examinee lies on his / her back on the surface of the top plate 32 and places the occipital region on the occipital region placement surface 12 of the head placement unit 11.

Here, the front-rear direction of the pillow 10 for medical examination coincides with the height direction of the examinee. The front side of the medical examination pillow 10 faces the lower side in the height direction of the inspected person (that is, the direction of the leg side in the height direction of the inspected person), and the rear side of the medical examination pillow 10 faces the inspected person's height. It faces the upper side in the height direction (that is, the direction of the head side in the height direction of the examinee).
The low resilience foam that forms the head placement portion 11 is deformed according to the shape of the head of the subject, and the head of the subject is firmly fixed to the head placement portion 11. Since the low resilience foam forming the head placement portion 11 has air permeability, the examinee does not feel discomfort such as stuffiness on the head.

  If necessary, the subject takes a posture of extending both arms. An examinee who takes both arms in an extended posture places his upper right arm on the upper arm placement surface 16L, slightly bends the right elbow outward and places the right forearm on the forearm placement surface 17L. Further, the examinee places the back of the right hand on the flat surface portion 18. Similarly, the subject places the left upper arm on the upper arm placement surface 16R, slightly bends the left elbow outward, places the left forearm on the forearm placement surface 17R, and places the back of the left hand on the flat portion 18. Put on.

  The angle α ° and the angle β ° satisfy Expressions (1) to (3), and the lateral width d2 of the upper arm placement surface 16L and the forearm placement surface 17L in the left-right direction has the above-described length. For this reason, the examinee can support the upper right arm and the right forearm from below by the arm placement portion 15L. Even if the subject has a hard shoulder joint or the like, the arms can be easily extended in the upper arm without placing a burden on the shoulder joint.

  The low resilience elastic foam that forms the upper arm placement surfaces 16L and 16R and the forearm placement surfaces 17L and 17R is deformed according to the shape of the left and right arms of the subject, and both arms of the subject are arm placement portions. It is easily and securely fixed on 15L and 15R. Furthermore, since the low resilience elastic foam forming the arm placement portions 15L and 15R has air permeability, the subject does not feel discomfort due to the stuffiness of both arms.

As long as both the arms are placed on the arm placement portions 15L and 15R, the examinee can easily maintain the arms extended posture for a long time. And by supporting both arms from below by the arm placement portions 15L and 15R, it is possible to easily prevent an excessive load on the shoulders and arms and to easily cause an accident such as dislocation in the shoulders and arms. Can be prevented.
In some cases, the person to be inspected needs to receive a drip treatment or the like while lying on his or her back on the top board 32. In such a case, instruments necessary for the treatment can be placed on the flat surface portion 18.
