Description

  The present invention relates to a cervical spine height measuring device for measuring a cervical spine height necessary for selecting or designing an appropriate pillow.

  For the human body, the cervical vertebra is structurally located at the top of the spinal column and is a combination of seven neck bones that support the head, called the vertebrae, in which there are nerves and surrounding blood vessels and muscles ing.

  Functionally, it is a nerve transmission path that connects the brain and body, which is important for living, and motor nerves, sensory nerves, and autonomic nerves are all distributed throughout the cervical spine.

  Specifically, the first and second vertebrae are related to breathing, the second and third are related to the head, the fourth and fifth are the nerves that control the neck and shoulders, Furthermore, there are nerves that control the functions of the hands and feet from the fifth to the seventh.

  For this reason, when a strong pressure is applied to the cervical vertebrae or there is a disorder, unpleasant symptoms such as damage and stiffness appear in the part of the cervical vertebra.

  Therefore, it is important to properly support the cervical vertebrae and maintain a proper sleeping posture during sleep, in order to obtain a good night's sleep and to maintain good health. (For example, refer to Patent Document 1).

  FIG. 3 is an explanatory diagram showing an ideal sleeping posture using a cervical support type pillow. As shown in the figure, in order to maintain an ideal sleeping posture using the cervical support pillow P, it is most important that the height of the cervical support P1 of the pillow P matches the cervical height H. It is also important to match the length of the cervical spine support portion P1 with the length L from the cervical spine portion to the scapula portion of the user.

  Thus, in order to select or design an appropriate pillow, it is necessary to know the height of the cervical vertebra of the user, and Patent Literature 2 proposes a cervical vertebra height measuring instrument for pillow design.

  However, the cervical spine height measuring device of Patent Document 2 needs to be used with the person to be measured lying on his back, and is not convenient. Further, since the cervical spine height changes depending on the posture in the supine position, it is difficult to measure the accurate cervical spine height in an ideal sleeping posture.

  Patent Document 3 proposes a head measuring instrument for digitizing the positional relationship between the neck and the back of the head and selecting an appropriate pillow.

However, since the head measuring instrument of Patent Document 3 is used by fixing the vertical substrate to the wall surface or the back plate of the chair, when measuring the cervical spine height, the measuring body is perpendicular to the vertical substrate. Need to slide in the direction to align with the cervical spine. As described above, the head measuring instrument of Patent Document 3 has a problem in that the configuration is complicated because the vertical position adjustment mechanism of the measuring body is necessary, and the use place is limited because it is a fixed type.
Utility Model Registration No. 3066086 JP 2002-336217 A Japanese Patent No. 2967473

  The problem to be solved by the present invention is to provide a cervical spine height measuring device capable of accurately and simply measuring the cervical spine height necessary for selecting or designing an appropriate pillow.

  The cervical vertebra height measuring instrument of the present invention is a lateral member that contacts the shoulder blades of both shoulders of a human body, a longitudinal member that is fixed to the lateral member and extends vertically upward from the lateral member, and a measurement that is attached to the longitudinal member. And is used by a measurer by hand. Here, the measuring member is attached to the longitudinal member at a position facing the cervical vertebra of the human body in a state where the lateral member is in contact with the shoulder blades of both shoulders of the human body, and is advanced and retracted toward the cervical vertebra of the human body. Installed as possible. In the present invention, when measuring the height of the cervical vertebra, the level member indicating the vertical degree of the vertical member is provided in order to accurately measure the cervical vertebra height with the vertical member mounted with the measurement member in a vertical state. It is said.

  In other words, the present invention improves the convenience by adopting the handy type that the measurer holds in hand, and the problem that the error is likely to occur in the measurement of the cervical spine height with the handy type is achieved by the leveling device. It is a solution that balances convenience and accuracy.

  In the present invention having such a configuration, the measurement member is advanced toward the cervical vertebra while holding the horizontal member in contact with the shoulder blades of both shoulders with the hand held by the measurer, and the distal end of the measurement member is By measuring the protruding length when contacting the cervical vertebra, the cervical spine height can be measured.

  Moreover, in this invention, in order to measure the protrusion length of a measurement member easily, it is preferable to provide the measurement member with the scale which shows the protrusion length from a vertical member.

  Furthermore, the vertical member can be provided with a scale indicating the vertical length from the position where the measuring member contacts the cervical vertebra of the human body to the horizontal member. As a result, the length from the cervical vertebra to the scapula can be easily measured, and the length of the cervical vertebra support P1 described above with reference to FIG. 3 can be designed or selected appropriately.

  According to the present invention, the height of the cervical spine can be measured accurately and simply, and an appropriate pillow for each user can be selected or designed easily and quickly.

  Embodiments of the present invention will be described below based on the embodiments shown in the drawings.

  1A and 1B show an embodiment of a cervical spine height measuring device according to the present invention, in which FIG. 1A is an exploded perspective view and FIG. 1B is an assembled perspective view.

  The cervical vertebra height measuring tool shown in FIG. 1 mainly includes a transverse member 1, a longitudinal member 2 fixed to the transverse member 1 and extending vertically upward from the transverse member 1, and a measuring member 3 attached to the longitudinal member 2. It is said.

  The transverse member 1 has a length that spans the scapula of both shoulders of the human body, and has a predetermined width (about 6 cm in the embodiment) in the vertical direction. The longitudinal member 2 is provided with a mounting hole 2a at a position facing the cervical vertebra when the lateral member 1 is brought into contact with the scapula, and the tip is formed in an arc shape in this mounting hole 2a. The member 3 is mounted so as to be able to advance and retract in a direction orthogonal to the vertical member 2. As a result, as will be described later, the measurement member 3 can advance and retract toward the cervical vertebra.

  In addition, the measuring member 3 is provided with a scale 4 indicating the protruding length from the vertical member 2. The scale 4 is provided with a position at the rear of the measuring member 3 as far as the width W of the vertical member 2 from the front end. Therefore, the numerical value of the scale 4 overlapping the rear end of the vertical member 2 represents the protruding length of the measuring member 3 from the vertical member 2.

  On the other hand, the vertical member 2 is provided with a scale 5 facing downward starting from a position corresponding to the most advanced position of the measuring member 3. The scale 5 indicates the vertical length from the position where the measuring member 3 abuts on the cervical vertebra to the lateral member, and thereby the vertical length from the cervical vertebra to the scapula can be measured.

  Furthermore, the vertical member 2 is provided with a level 6. Since the level of the vertical member 2 can always be grasped by the level 6, the vertical member 2 can always be maintained in the vertical state when measuring the cervical spine height.

  FIG. 2 is a side view showing a usage state of the cervical spine height measuring device according to the present invention. As shown in the figure, when measuring the height of the cervical spine, the person to be measured looks at the floor surface about 3 m ahead, and in this state, the person holding the measuring member 3 holds the vertical member 2, for example. The horizontal member 1 is horizontally brought into contact with the apex portions of the scapulas of both shoulders so as to face the cervical vertebra, and the vertical member 2 is kept vertical while looking at the level 6. Here, the length from the scapula to the cervical vertebra varies slightly depending on the physique of the person being measured. However, since the horizontal member 1 has a width in the vertical direction, the horizontal member 1 can be slid up and down to The position of the measuring member 3 is adjusted so as to oppose the cervical vertebra by changing the position of contact with the apex of the scapula.

  Then, as shown in FIG. 2, the measuring member 3 is advanced and brought into contact with the cervical vertebra part, and the cervical spine height is measured by the scale 4 (about 3 cm in the embodiment). Further, the scale 5 measures the length from the cervical vertebra to the apex of the scapula (in the example, about 14 cm). Based on the height of the cervical vertebra and the length from the cervical vertebra to the apex of the scapula, the pillow suitable for the measurement subject is selected or designed.

  The present invention is applicable both for selecting an appropriate pillow from ready-made pillows and for designing custom-made pillows.

One Example of the cervical vertebra height measuring device of this invention is shown, (a) is a disassembled perspective view, (b) is a perspective view of an assembly state. It is a side view which shows the use condition of the cervical vertebra height measuring device of this invention. It is explanatory drawing which shows the ideal sleep posture using the cervical spine support type pillow.
