Patent Document 2 discloses a combination sleep pillow having a structure in which a double pillow that carries a head and a large-diameter cylindrical pillow that carries a neck can be attached and detached by a Velcro fastener so that the user can use various forms. Has been proposed.

Utility Model Registration No. 3138540 JP-A-10-52347

  Here, the pillow for radiation therapy and examination as disclosed in Patent Document 1 can be fixed at a fixed position on the treatment table or examination table by hanging the portion from the neck to the head of the patient. And a contour-shaped neck support surface corresponding to the neck and a contour-shaped head support surface corresponding to the back of the head. Because there are individual differences in the shape and size of the patient's head, in order to fix the portion from the neck to the head, the neck support surface and head support that match the patient's head shape and size It is necessary to use a pillow with a face. However, conventionally, a pillow that can flexibly cope with individual differences in the shape and size of a patient's head has not been proposed.

  In addition, in general pillows, as disclosed in Patent Document 2, it has been proposed to connect a plurality of pillows and use them in various modes, but it matches the shape and size of the user's head. A pillow having a neck support surface and a back head support surface has not been proposed for a pillow that can flexibly cope with individual differences in head shape and size.

  In view of this point, the problem of the present invention is that it can be used in combination according to the shape and size of the human neck to the head, and the body position (the part from the neck to the head) can be combined. The present invention is to propose a split pillow set of linked pillows that can be changed in height, angle, etc.

In order to solve the above-mentioned problem, the present invention is a split pillow set used to configure a connected pillow of different shapes and sizes,

An original curved surface is desirable. Further, it is desirable that the abutment surface is a three-dimensional curved surface defined by a concave curve in the front-rear direction and defined by a symmetrical concave curved surface in the upper surface width direction. In this way, if these support surfaces are formed so as to follow the anatomical shape from the human neck to the head, the head placed on the head is securely fixed at a fixed position. And can be repeatedly fixed at the same position.

  In this case, the front divided pillow obtained by dividing the coupled pillow at a position between the deepest part of the back head support surface and the rear edge of the head contact surface is the first divided pillow, and the rear The side divided pillow can be the second divided pillow. For example, if a variety of long and short sizes are prepared as the second divided pillow, a connected pillow that matches the head size can be obtained by selecting an appropriate one from these.

  Here, on the rear edge of the top contact surface on the top surface of the coupled pillow, a cut-out part is formed that is cut into a symmetric concave curved surface whose center is the deepest part of the rear edge in the width direction of the upper surface. It is desirable that When the size of the user's head is long in the vertical direction, this can be dealt with by projecting the tip of the top of the head backward from the cutout portion. Therefore, there is an advantage that it is not necessary to prepare a large number of divided pillows.

  Next, the split pillow set of the present invention is used to configure a connecting pillow used as a medical pillow for fixing a portion of the patient from the neck to the head at the time of treatment or examination by radiation. Can do.

  In such a medical pillow, it is necessary to accurately set the radiation irradiation position with respect to the patient's head, etc. For this purpose, the height position of the part from the patient's neck to the head, the vertical direction It is necessary to set the position in the (head-and-foot direction) and the position in the width direction accurately, and to fix the position. If the combination pillow as a medical pillow is configured using the divided pillow set of the present invention, a shape and size most suitable for each patient can be provided, so that the patient's head is fixed at a desired position. And reproducibility of fixing repeatedly at a desired position is improved.

  In the divided pillow set of the present invention, the second divided pillow is selected so as to fit the shape and size of the user's neck from the head, and this is connected to the first divided pillow and integrated. A coupled pillow having a neck support surface, a back head support surface, and a crown contact surface corresponding to individual differences is obtained. If a plurality of first divided pillows having different shapes and sizes are prepared, the applicability to the shape and size of the user from the neck to the head can be further enhanced. Therefore, the split pillow set of the present invention can be used in combination so as to obtain a coupled pillow that fits the shape and size of the human neck from the head. A connected pillow that can be set in a desired state can be realized.

(Effects of split pillow set)
The effect of the medical linked pillow 1 constituted by the first and second divided pillows 31 and 32 will be described. First, one first divided pillow 31 and one second divided pillow 32 are selected from the divided pillow set 30 so as to match the shape and size of the patient's neck and head. By connecting and integrating both of the selected divided pillows 31 and 32, the medically connected pillow 1 that substantially conforms to the shape and size of the patient from the neck to the head can be obtained. Thus, by selecting the first and second divided pillows from the divided pillow set 30, the shape and size of the medical linked pillow 1 can be adjusted to suit the patient.

  Further, the constructed medical pillow 1 includes a rear wall 7 having a top contact surface 6 that contacts the patient's top, and the top contact surface 6 of the rear wall 7. The rear end edge 15 is formed with a concave curved cutout 21. When the size of the patient's head is long in the vertical direction, this can be dealt with by projecting the tip of the top of the head backward from the cutout portion 21. In this way, according to the shape and size of the patient's head, the position where the patient's head is placed on the medical linking pillow 1 is finely adjusted, and the portion of the patient's neck that is hung on the head is adjusted. It can be fixed at a desired position and angle.

  In the medical linkage pillow 1 of the present example, the tip of the top of the patient's head rides on the cut-out portion 21 cut into a concave curved surface, and the patient's head is positioned below the occipital support surface 4. And supported from both sides. Therefore, the movement of the head in the width direction X can be restricted by the concave curved upper surface of the cutout portion 21. Therefore, the effect that the patient's head can be reliably positioned and fixed also in the width direction X is obtained.

  The rear end edge deepest portion C of the rear wall portion 7 and the top deepest portion A of the top portion 2a extending in the width direction of the neck support surface 2 are set to the same height. Thus, the state where the patient's head placed on the occipital support surface 4 is supported by three points (A, F, F) at the same height position higher than the concave curved occipital support surface 4 is present. It is formed. Since the position in the longitudinal direction and the width direction of the head is defined by the three-point support, the effect of improving the positioning and fixing properties of the head and the reproducibility of positioning can be obtained.

(Other embodiments)
In this example, as shown in FIG. 5 (a), the medical linking pillow 1 is divided into two parts in the front-rear direction at a position between the deepest portion B of the back head support surface 4 and the rear edge 15 of the head contact surface 6. The front and rear divided pillows obtained in this way are the first divided pillow 31 and the second divided pillow 32. Instead, as shown in FIG. 5 (b), the medical pillow 1 is divided into two parts at the front and rear at a position 43 between the top 2a of the neck support surface 2 and the deepest part B of the back head support surface 4. The front and rear divided pillows obtained in this way can also be used as the first divided pillow 41 and the second divided pillow 42. Further, as shown in FIG. 5 (c), the position 54 between the top 2 a of the neck support surface 2 and the deepest part B of the occipital support surface 4 and the deepest part B of the medical linkage pillow 1. It can also be set as the divided pillow set which consists of the divided pillows 51, 52, and 53 obtained by dividing into three front and back in the position 55 between the head and the rear-end edge 15 of the head top contact surface 6.

  Next, in the above-described medically connected pillow 1, the cutout portion 21 is formed on the upper end surface of the rear wall portion 7 so that the position where the patient's head is placed can be finely adjusted. For example, if a plurality of types of divided pillows are prepared, it is possible to configure a medically connected pillow that matches the shape and size of each patient's head without providing such a cutout 21. In such a case, as shown in FIG. 6, a medical linked pillow 1 </ b> A having a shape in which the cutout portion 21 is omitted can be used. Therefore, the shape of the divided pillow may be changed correspondingly.

  Further, as shown in FIG. 7A, a medical pillow having a shape in which the rear wall portion 7 is omitted from the medical linked pillow 1 shown in FIG. 1 is known. Such a medical pillow can be provided as a medical linking pillow using the divided pillow according to the present invention. In this case, for example, the divided pillows obtained by dividing the front and back into two at the position 73 between the top 2a of the neck support surface 2 and the deepest part B of the occipital support surface 4 are first and second divided pillows, respectively. It can be set as the medical connection type pillow 1B using it as 71,72.

  On the other hand, each of the above examples applies the present invention to configure a medical pillow, but the split pillow set of the present invention is not limited to a medical pillow but is also used to configure other pillows. be able to. Moreover, the shape of each divided pillow and the shape of the coupled pillow constituted by these are not limited to the shapes of the above examples, but can take various shapes.
