FIG.

  As shown in FIGS. 1 and 2, this sphygmomanometer includes a square box-shaped case 10, an arm band 20 accommodated in the case 10, a winding drum 110 of the arm band 20, an air pump 80 ( 5), and other means (not shown) necessary for blood pressure measurement, a display unit, and the like.

  The case 10 has an arm mount 11 on which the upper arm of the subject is placed on the upper surface, an opening (feeding portion) 12 for feeding the arm band 20 on one side across the arm mount 11, and a connector insertion port on the other side. 13 In the connector insertion opening 13, a frame-shaped lock guide 50 (tip lock portion) for locking the connector 30 at the tip of the extended armband 20 is disposed.

  The arm band 20 is wound around the winding drum 110 from the base end side, and the connector 30 at the distal end is drawn out from the opening 12 for feeding and locked to the lock guide 50 in the connector insertion port 13. Thus, an intermediate portion between the distal end and the proximal end is wound around the upper arm placed on the arm rest 11. The feeding opening 12 is formed large so that the armband 20 is sufficiently wound around the upper arm. For the same reason, the armband 20 is drawn from the take-up drum 110 from the side closer to the arm rest 11. In addition, concave receiving portions 14 for receiving both side portions of the connector 30 are provided on the case side walls on both sides of the opening portion 12 for feeding.

  The connector 30 is made of a hard resin band plate, and is used to introduce air into the handle 31 for grasping by hand, the two lock holes (locked portions) 32, and the air bag 22 inside the arm band 20. The air inlet 40 is provided.

  Further, as shown in FIG. 3, the lock guide 50 is a frame having a space into which the connector 30 can be inserted. When the connector 30 is inserted into the space, the lock guide 50 and the lock hole 32 on the connector 30 side are formed. A lock protrusion 52 to be engaged, an eject lever 51 for releasing the lock, and a slit 53 into and out of a cam 123 of the lock lever 120 described later are provided. The eject lever 51 is formed in a thin frame shape so as to have flexibility, and a lock projection 52 is disposed in the vicinity of the base thereof.

  Further, in the vicinity of the lock guide 50, as shown in FIG. 5, when the connector 30 is inserted into the lock guide 50 and locked, the air discharge port of the air pump 80 connected to the air inlet 40 on the connector 30 side. 82 is arranged.

  As shown in FIGS. 3 and 4, the take-up drum 110 is attached to the case 10 via a shaft 130, and is a spring that is a rotation urging member interposed between the take-up drum 110 and the shaft 130. (Not shown) is always urged to rotate in the direction of arrow A (the direction in which the armband 20 is wound). On the circumference of both ends of the winding drum 110 in the axial direction, ratchet claws 111 for locking the rotation of the winding drum 110 are provided.

  Further, between the winding drum 110 and the lock guide 50, when the connector 30 at the tip of the arm band 20 is locked to the lock guide 50, the rotation of the winding drum 110 is locked and the base of the arm band 20 is locked. A lock lever (drum lock mechanism) 120 for fixing the end side is disposed. The lock lever 120 is swingably attached to the case 10 via a shaft 140 at a position parallel to the winding drum 110.

  The lock lever 120 has a lock claw 121 at a position where it engages with the ratchet claw 111 at both ends of the winding drum 110, and a cam 123 at a position corresponding to the slit 53 of the lock guide 50. The lock lever 120 is urged in the direction of arrow B by a spring (not shown). When the cam 123 is not pushed, the lock claw 121 is held at a position away from the ratchet claw 111 by the urging force of the spring. . The cam 123 is pushed by the connector 30 when the connector 30 at the tip of the armband 20 is inserted into the lock guide 50, so that the lock lever 120 swings in the direction opposite to the arrow B direction against the spring. Let

Next, the operation will be described.
In the initial state, the armband 20 is wound around the winding drum 110 and is housed inside the case 10. When blood pressure is measured by the subject himself / herself from this state, the left upper arm is placed on the arm rest 11, the handle 31 attached to the connector 30 is pulled with the right hand, and the armband is pulled out from the opening 12 for feeding. 20 is pulled out and wound around the upper arm placed on the arm rest 11.

  When the connector 30 at the tip of the armband 20 is inserted into the connector insertion port 13 of the case 10 with the armband 20 wrapped around the upper arm, the connector 30 is locked to the lock guide 50 and the winding of the armband 20 is completed. . At this time, the arm band 20 wound around the take-up drum 110 is pulled out against the rotational biasing force, so that the tension at this time becomes the initial tightening force when wound around the upper arm.

  Here, in the state before locking, as shown in FIG. 4A, the lock lever 120 is subjected to the rotational force in the direction of arrow B, and the ratchet pawl 111 provided on the take-up drum 110 is locked. Since the nail | claw 121 is separated, the winding drum 110 can rotate. A cam 123 provided on the lock arm 120 enters the slit 53 of the lock guide 50.

  However, as shown in FIG. 4B, when the connector 30 is inserted into the connector insertion slot 13, the connector 30 enters the lock guide 50, and the lock protrusion 52 and the lock hole 32 are caused by the flexibility of the eject lever 51. Engages and the tip of the armband 20 is locked to the case 10. At the same time, when the connector 30 hits the cam 123 of the lock lever 120 protruding from the slit 53 of the lock guide 50, the cam 123 is pushed down, and as a result, the lock lever 120 is moved in the direction opposite to the arrow B direction. As a result, the lock claw 121 of the lock lever 120 engages with the ratchet claw 111 of the take-up drum 110, and the rotation of the take-up drum 110 is locked. Therefore, at this stage, the arm band 20 is wound around the upper arm while the proximal end side and the distal end side are fixed at the same time.

  Further, when the connector 30 is locked to the lock guide 50 in this way, the arm inlet 20 side air inlet 40 and the air outlet 80 of the air pump 80 are connected as shown in FIG. Blood pressure can be measured by injecting air into the band 20. Even if air is injected into the armband 20, the take-up drum 110 is locked, so it does not rotate and the armband 20 does not loosen.

  When the measurement is completed, if the eject lever 51 provided in the lock guide 50 is pushed in the direction of releasing, the lock is released and the connection between the tip of the armband 20 and the case 10 is released. When the connector 30 is further pulled out from the lock guide 50, the cam 123 of the lock lever 120 is also released from the pushed-down state by the connector 30. Therefore, the lock lever 120 is rotated again in the direction of arrow B by the force of a spring (not shown). As a result, the lock claw 121 of the lock lever 120 is detached from the ratchet claw 111 of the take-up drum 110, and the take-up drum 110 is again moved. The armband 20 that is rotated in the direction of arrow A and unlocked is taken up by the take-up drum 110 and accommodated in the case 10. Further, when the connector 30 is pulled out from the lock guide 50, the coupling between the air inlet 40 and the air outlet 82 is also released.

  As described above, according to the sphygmomanometer including the armband take-up device of the present embodiment, the armband 20 can be extended from the case 10 by the required length during use, and the armband 20 can be automatically used after use. Therefore, the armband 20 can be stored so as not to get in the way. Also, one arm is placed on the arm rest 11, the tip of the armband 20 is pulled out with another hand, and the connector 30 at the tip is inserted into the connector insertion port 13 of the case 20 to be locked. Since both ends of the armband 20 can be locked in a state where the tension by the rotation bias of the take-up drum 110 is applied, the armband 20 can be wound around the arm with an appropriate pressure. Therefore, by introducing air into the armband 20 in this state, it is possible to efficiently apply air pressure to the arm via the armband 20 and to measure blood pressure.

  In this way, the blood pressure can be measured simply by placing the arm on the arm rest 11 and the arm band 20 is extended and locked by the other hand, so that the blood pressure can be measured as in the prior art. Compared to wrapping an arm band around the arm with one hand, it is easier to handle. In addition, the structure is simple compared to a conventional arm-in type sphygmomanometer, so it is compact and inexpensive, and it is not necessary to pass an arm through a narrow hole, so that operability is good.

  Also, if the tip of the armband 20 is pulled out of the case 10 and locked, the air inlet 40 on the armband 20 side and the air outlet 82 on the air pump 80 side can be automatically connected. When the air pump 80 is disposed therein, the air pump 80 can be easily laid out without being disturbed by the winding drum 110.

  In addition, by providing the hard material connector 30 provided at the tip of the armband 20 with the lock hole 32 and the air injection port 40 together, and inserting the connector 30 into the connector insertion port 13 on the case 10 side, Since the air inlet 40 and the air outlet 82 on the pump 80 side are connected at the same time as the distal end of the arm band 20 is locked, the distal end of the arm band 20 can be securely locked and the air passages are connected to each other. Can also be done reliably. In addition, by providing the connector 30 made of a hard material at the tip of the armband 20 having flexibility, there is also an advantage that the tip of the armband 20 can be easily handled.

  Further, since the connector 30 provided at the tip of the armband 20 is received by the receiving portion 14, it is possible to apply a winding stop to the armband 20 biased in the winding direction. 30 inadvertent pop-outs can be prevented, and preparation for the next smooth extension of the armband 20 can be made.

  Although the armband winding device of the present invention may be configured integrally with the main body of the sphygmomanometer as in the above embodiment, it is configured separately from the main body of the sphygmomanometer, It may be connected. In that case, a tube may be connected to the air discharge port 82.
