  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1A is a perspective view of the sphygmomanometer 1, and FIG. 1B is a cross-sectional view of the sphygmomanometer 1. The sphygmomanometer 1 is configured to be compact and simple for home use, and a box-shaped arm insertion block 2 is formed with an arm insertion hole 3 penetrating in the front-rear direction. A cylindrical cuff ring (not shown) is arranged, and a cuff band 4 holding a blood-proof bag is arranged at the outer peripheral position of the cuff ring.

  The cuff band 4 is connected to an automatic winding mechanism (such as an electric motor), and when the switch 5 is turned on, the cuff band 4 is wound and the blood-insulating bag is wound around the upper arm 6A at a predetermined timing. The ischemic bag is inflated to occlude the artery of the upper arm 6A, and blood pressure is measured.

  An elbow support base 8 that is attached to the rear side wall 2a of the arm insertion block 2 and extends to the back side (rear side) is provided at the lower part of the arm insertion hole 3 near the outlet 3a.

  The elbow support base 8 is for placing the elbow 7 of the upper arm 6 </ b> A inserted into the arm insertion hole 3.

  Thus, by providing the elbow support base 8 near the outlet 3a of the arm insertion hole 3 of the arm insertion block 2, the sphygmomanometer 1 is placed on the table 9 or the like, and the measurer puts the upper arm 6A in the arm insertion hole 3. When the arm is inserted, placing the elbow 7 on the elbow support base 8 is a measure of how far the upper arm 6A should be inserted into the arm insertion hole, so blood pressure can always be measured at a fixed measurement position. Reliability of measurement accuracy is improved.

  Moreover, since the elbow support base 8 should just be provided only in the exit 3a vicinity of the arm insertion hole 3 of the arm insertion block 2, it can be provided compactly.

  When the sphygmomanometer 1 is placed on the table 9 or the like, depending on the height of the table 9 or the like, the insertion angle of the upper arm 6A and the center of the arm insertion hole 3 may not coincide with each other, and the cuff belt 4 is firmly attached to the upper arm 6A. Can not be wrapped around.

  Therefore, as shown in FIG. 2 (a), the lower part of the arm insertion block 2 on the outlet 3a side of the arm insertion hole 3 is supported on the base base 10 of the sphygmomanometer 1 by the hinge member 11, and the arm insertion block 3 is It can be tilted to the side (see arrow a). In this case, the elbow support base 8 extends beyond the hinge member 11.

  If comprised in this way, if a measurer will insert the upper arm 6A in the arm insertion hole 3, and will place the elbow 7 on the elbow support base 8, the arm insertion block 2 will be tilted back by the weight of the elbow 7, Since the center of the arm insertion hole 3 coincides with the insertion angle of the upper arm 6A, the cuff band 4 can be tightly wound around the upper arm 6A, so that the reliability of measurement accuracy is improved.

  2B, the arm insertion block 2 and the base table 10 are fixed, and the base table 10 is supported on a table or the like 9 by a hinge member 11, so that the arm insertion block 3 and the base table 10 are fixed. Can be tilted backward (see arrow a).

  As shown in FIG. 3 (a), the elbow support base 8 is formed by forming an elbow rest surface 8a in a lateral concave arc surface, and when the elbow 7 is placed on the elbow support base 8, Since the displacement of the direction can be prevented, stable blood pressure measurement can always be performed, and variations in measurement accuracy can be reduced.

  Further, as shown in FIGS. 3A and 3B, if the back of the elbow support surface 8 a of the elbow support base 8 is formed on the raised surface 8 b, the elbow 7 is placed when the elbow 7 is placed on the elbow support base 8. Can be recognized by tactile sensation, and displacement of the elbow 7 in the depth direction can be prevented, so that stable blood pressure measurement can always be performed, and variations in measurement accuracy can be reduced.

  If the elbow support base 8 is made of a soft material (for example, rubber material or the like and having a hardness of about 70 to 90), pain of the elbow 7 placed on the elbow support base 8 can be reduced.

  In this case, if the elbow support portion 8c of the elbow support base 8 is made of a soft material and the attachment portion 8d to the arm insertion block 2 is made of a hard material (for example, hard synthetic resin or metal), the elbow placed on the elbow support portion 8c. 7 can be reduced, and the attachment force to the arm insertion block 2 can be sufficiently secured.

  Although the elbow support base 8 is not specifically illustrated, the elbow support base 8 can be formed of an inflatable / defensible air bag. If it is this structure, while being able to reduce the pain of the elbow 7 set | placed on the elbow support stand 8 made from an air bag, the elbow support stand 8 can be accommodated compactly by shrink | contracting an air bag.

  In addition, the air bag can be inflated and deflated by using an air supply pump and an air exhaust valve for the ischemic bag built in the sphygmomanometer 1 as means for injecting / extracting air from the air bag. .

  As shown in FIG. 4, if the elbow support pedestal 8 is supported by a hinge member 11 at the lower part near the outlet 3a of the arm insertion hole 3 so as to be swingable up and down, the elbow support pedestal 8 is inserted into the arm when not in use. Since it can be folded to the block 2 side (see the two-dot chain line b), the elbow support base 8 can be stored in the arm insertion hole 3 in a compact manner.

  As shown in FIG. 5 (a), if the arm support base 12 for placing the lower arm 6B (see FIG. 5 (b)) is provided continuously to the elbow support base 8, the entire arm can be supported. The posture of the entire arm during measurement becomes stable.

  Further, when the elbow support base 8 is supported by the hinge member 11 so as to be swingable up and down, and the arm support base 12 connected in a chain shape is used, the arm support base 12 is as shown in FIG. Moreover, since it can be folded to the arm insertion block 2 side together with the elbow support base 8, the elbow support base 8 and the arm support base 12 can be stored in the arm insertion hole 3 in a compact manner. The arm support base 12 connected in a chain shape is bent at each joint part in the folding direction, and has a structure that is not bent by being locked by a stopper at each joint part in the extending direction.

  In addition, as shown in FIG. 6A, the arm support base 12 may be a telescopic rod.

  As shown in FIGS. 5 (a) and 6 (b), when the grip portion 12a that can be gripped by the hand 6C is provided at the tip of the arm support base 12, the palm side of the hand 6C (the blood vessel side on which blood is desired to be blocked). Is naturally upward, so blood pressure can be measured accurately.

  As shown in FIG. 7A, when the elbow 7 (R) of the right arm is viewed from the front, the bone portion 7a protruding from the elbow 7 (R) is inward. Further, as shown in FIG. 7B, when the elbow 7 (L) of the left arm is viewed from the front, the bone portion 7a protruding from the elbow 7 (L) is inward.

  Therefore, if the elbow support surface 8a of the elbow support base 8 is flat, the elbow 7 (R, L) position fixing is not stabilized by the protruding bone portion 7a, so that the measurement site is the elbow 7 (R) of the right arm. For example, as shown in FIG. 7 (a), a recess 8e that fits the bone 7a of the right arm elbow 7 (R) may be formed on the elbow rest surface 8a of the elbow support base 8, and the measurement site is the elbow 7 of the left arm. In the case of (L), as shown in FIG. 7B, a recess 8f that fits the bone 7a of the left arm elbow 7 (L) may be formed on the elbow rest surface 8a of the elbow support base 8. .

  However, since the measurer does not know which arm to measure as the left or right arm, as shown in FIG. 7C, the elbow 7 (L , R), the depressions 8e and 8f that match the bones are formed.

  Thus, as shown in the figure, when the right arm elbow 7 (R) is placed on the elbow rest surface 8 a of the elbow support base 8, the bone 7 a is aligned with the recess 8 e and the elbow 7 (R) position is stabilized. At the same time, if the left arm elbow 7 (L) is placed on the elbow support surface 8a of the elbow support base 8 as shown in FIG. 7 (d), the bone portion 7a is aligned with the depression 8f and the elbow 7 (L) position is fixed. Become stable.

  If the elbow support base 8 is made of low elasticity urethane, the left and right arm elbows 7 (L, L) can be formed without forming the depressions 8e and 8f as described above on the elbow rest surface 8a of the elbow support base 8. Regardless of the elbow shape of R), the elbow support base 8 fits to the elbow 7 (L, R), so that the elbow position is stabilized.

  As shown in FIG. 8 (a), an upright portion 8c can be provided at the tip of the elbow support base 8 that is supported by a hinge portion 8b so that it can swing up and down (see arrow c). . In order to erect this standing part 8c, the leaf spring 13 that urges the standing part 8c in the standing direction is insert-molded across the elbow support base 8 and the standing part 8c.

  If comprised in this way, by providing the standing part 8c in the front-end | tip of the elbow support stand 8, a measurer inserts an arm in the arm insertion hole 3, and the elbow 7 of the bent arm is applied to the standing part 8c. The elbow 7 can be positioned, and when the elbow 7 is subsequently extended as shown in FIG. 8 (b), the upright portion 8c falls down linearly against the urging force of the leaf spring 13 accordingly. If the elbow 7 does not hit 8c, the pain of the elbow 7 can be reduced.

  As shown in FIG. 9, a female screw 2b is formed on the rear side wall 2a of the arm insertion block 2 in the lower portion of the arm insertion hole 3 near the outlet 3a, and a male screw 8g screwed to the female screw 2b is attached to the elbow support base 8. The position in the insertion direction of the upper arm 6A of the elbow support base 8 can be adjusted by attaching and changing the screwing position of the male screw 2b (see arrow d). In addition to the female screw 2b and the male screw 8b, a click stop structure or the like can be employed.

  Therefore, even when a measurer having a different length of the upper arm 6A is used, the elbow 7 can be placed at an appropriate position.

  If the elbow support base 8 is supported so as to be movable back and forth between the vicinity of the entrance of the arm insertion hole 3 and the vicinity of the exit 3a, the elbow support base 8 is moved to the vicinity of the entrance of the arm insertion hole 3 and the elbow support base 8 is moved. Since the upper arm 6A can be inserted into the arm insertion hole 3 together with the elbow support base 8 with the elbow 7 placed on the arm insertion position 3, the position where the elbow 7 is placed is easy to understand. It becomes possible to solve the shortage.

  Further, the arm insertion block 2 is supported by the base table 10 so as to be movable in the arm insertion direction, and the elbow support table 8 is attached to the base table 10 corresponding to the vicinity of the entrance of the arm insertion hole 3 of the arm insertion block 2. Then, by moving the arm insertion block 2 with the elbow 7 placed on the elbow support base 8, the upper arm 6A can be inserted into the arm insertion hole 3 together with the elbow support base 8, so the elbow 7 is placed. Since the position is easy to understand, it is possible to eliminate excessive or insufficient insertion of the upper arm 6A with respect to the arm insertion hole 3. Further, since the arm insertion block 2 is merely moved while the elbow 7 is placed on the elbow support base 8, the measurer can measure in a natural posture without being bent forward.

  Further, when the elbow support pedestal 8 is provided with detection means (such as a switch) for detecting that the measurer has placed the elbow 7, the detection means detects that the measurer has placed the elbow 7 on the elbow support pedestal 8. Then, since a notification sound or the like can be generated for notification, the measurer can recognize that the elbow 7 is placed at an appropriate position, and can measure with confidence. Further, when detection is performed by the detection means, automatic measurement can be performed by starting automatic winding of the cuff belt 4 and the like.
