Description

  The present invention relates to an arm band of a sphygmomanometer, and more particularly, to an arm band characterized by an elastic plate that is disposed outside a bladder and holds its own annular form.

  As shown in FIG. 2 (perspective view) and FIG. 3 (cross-sectional view), an armband of a sphygmomanometer generally has an air bag 91 and an elastic plate 92 arranged in a cloth bag 90. 93 is connected, and a hook-and-loop fastener 94 is attached to the outside of the cloth bag 90. The elastic plate 92 is disposed outside the air bag 91 and is used for holding the armband in an annular shape by its own elastic force, and has a uniform thickness as shown in FIG. , Having a perfect circular cross-sectional shape, part of which is a discontinuous portion 92a.

However, the elastic plate 92 as shown in FIG. 4A has the following problems AC.
A) It is difficult to open the elastic plate 92 for mounting on the arm.

That is, since the cross-sectional shape is a perfect circle, the elastic plate 92 must be opened before being attached to the arm. Specifically, in order to open the elastic plate 92, the elastic plate 92 needs to be pulled with a moderate strength. In order to attach the elastic plate 92 in the open state to the arm as it is, some degree of familiarity is required.
B) The end of the elastic plate 92 bites into the arm.

In the case of the elastic plate 92 having a true circular cross-sectional shape, when the elastic plate 92 is worn on the arm, the edge of the discontinuous portion 92a bites into the arm due to the elastic force and often gives pain to the subject. Such a tendency is remarkable especially in a thick arm.
C) Arm thickness and shape such as thin arms, thick arms, arms with large inclination (arms with large thickness change from shoulder to elbow), straight arms (arms with small thickness change from shoulder to elbow), etc. Corresponding deformation is not possible and it is difficult to fit the arm.

  This is because the thickness of the elastic plate 92 is uniform and the cross-sectional shape is a perfect circle, so that the elastic plate has a shape that is easily adapted to everyone, even though the thickness and shape of the arms are various. This is because it is not 92.

On the other hand, there is an elastic plate as shown in FIG. 4B as an elastic plate that facilitates attachment to the arm and enhances the fit (see, for example, Patent Document 1). The elastic plate 92 'described in Patent Document 1 is formed so that the thickness gradually increases from both end portions (discontinuous portions 92'a) toward the central portion, thereby gradually increasing the rigidity. The wall thickness and rigidity are maximum at the center.
Japanese Patent Laid-Open No. 61-238229

  However, the elastic plate 92 ′ described in Patent Document 1 also has a thickness that is gradually increased from both ends toward the center. Therefore, in terms of adaptability to various arms, the deformation corresponding to the arms does not occur. There is a need for an elastic plate that is not flexible, has room for improvement, and has superior performance.

  The present invention has been made by paying attention to such conventional problems and actual situations, and is an elastic plate that is easy to perform the wearing operation on the arm, does not give pain after wearing, and exhibits excellent fit characteristics. An object of the present invention is to provide an arm band of a blood pressure monitor provided.

  In order to achieve the above-mentioned object, the armband of the sphygmomanometer according to the present invention has an air bag and an elastic plate disposed inside the air bag for holding its own annular shape inside. The elastic plate is characterized in that its inner peripheral surface is substantially circular and its outer peripheral surface is polygonal.

  This elastic plate has a cross-sectional shape in which the circular inner peripheral surface is inscribed (not strictly inscribed) with the polygonal outer peripheral surface, and is thick at the corners of the polygon and thin at the sides. Become. Accordingly, the thickness of the elastic plate is substantially changed, the deformation corresponding to the variation of the arm can be made, the bite into the arm is difficult, and the fit is good.

  According to the armband of the sphygmomanometer of the present invention, since the inner peripheral surface is substantially circular and the outer peripheral surface is provided with an elastic plate having a polygonal shape, not only the wearing operation on the arm is easy, but also the arm It is difficult for the end to bite into the arm when worn on the wrist, and does not hurt the subject. In addition, it can be deformed according to arm variations and has good fit.

  Hereinafter, the present invention will be described based on embodiments. However, the present invention is characterized by the elastic plate in the arm band of the sphygmomanometer, and the structure of the arm band may be the normal one shown in FIG. Of course, the description of the action of the elastic plate also applies to the armband provided with the elastic plate.

  A perspective view of an elastic plate according to an embodiment provided in an arm band of a sphygmomanometer is shown in FIG. 1A, and a cross-sectional view thereof is shown in FIG. The elastic plate 1F has an inner peripheral surface 1a that is substantially circular and an outer peripheral surface 1b that is formed in a polygonal shape (substantially hexagonal here). With this structure, the corner of the polygon becomes the thick portion 35 and the side becomes the thin portion 36. Therefore, the elastic plate 1F results in a form in which the wall thickness is changed, can be deformed corresponding to the variation of the arm, does not easily bite into the arm, and has good fit. Moreover, since the other end part 28 is extended outside the one end part 27, the attachment to an arm is also easy.

They are a perspective view (a) of an elastic board concerning an embodiment with which an arm band of a sphygmomanometer is equipped, and a sectional view (b) of the elastic board. It is a perspective view which shows a general armband. It is sectional drawing which shows the inside of the arm band of FIG. It is a perspective view (a) of the elastic board which concerns on the example of a prior art arrange | positioned inside the arm band of FIG. 2, and a perspective view (b) of the elastic board which concerns on another prior art example.
