DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cuff wrapping device for a finger-type blood pressure monitor for measuring blood pressure with a finger or the like.

[0002]

2. Description of the Related Art In an electronic sphygmomanometer for measuring blood pressure with a finger or the like, a cuff wrapping device as shown in FIG. 5 is used to easily wrap a cuff around a finger. In FIG. 5, case 23
The cuff 22 is housed therein so that a finger can be inserted. The extended protruding end of the cuff 22 provided with the rubber bag 21 is fixed to the slider 24. A locking claw 25 is set on a slider 24 slidably provided on the case 23. As shown in FIG. 6, the locking claw 25 is provided with an engaging portion 27 of a rack 26 set along the sliding direction of the slider.
And the slider 24 does not move in the cuff loosening direction. When the slider 24 slides to measure the blood pressure and the cuff 22 is wound around the finger, the locking claw 25 is elastically deformed and the engaging portion 27 of the rack 26 is engaged.
When the appropriate cuff wrapping force is obtained, the locking claw 25 is engaged with the engaging portion 27 to fix the slider 24, and the cuff wrapping state is maintained. In this state, air can be supplied to the rubber bag 21 to tighten the finger, and the blood pressure can be measured. After the blood pressure measurement is completed, the button 28 is pressed to move the locking claw 25 downward, so that the engagement between the locking claw 25 and the engaging portion 27 can be released. The slider 24 is free, and the cuff 22 can be loosened by sliding.

[0003]

However, in the above cuff winding device, when the slider is slid to wind the cuff, the force for sliding the slider before and after the engaging claw passes over the engagement portion is obtained. They tended to change, often applying great force to the slider. For this reason, there has been a problem that the cuff wrapping force varies, and in particular, the cuff tends to be overtightened. If the cuff is wound tightly, blood is likely to be congested on the finger, which may cause pain to the user.
An object of the present invention is to provide a cuff wrapping device for a finger-type sphygmomanometer that can easily obtain a proper cuff wrapping force.

[0004]

In order to solve the above-mentioned problems, the present invention provides a case body having a finger insertion portion, a cuff stored in the finger insertion portion of the case body, and a case book.
A slider slidable on the body, and
Slider fixed to any sliding position on the base body
A mechanism is connected to one end of the cuff, and
Increase or decrease the inner diameter of the cuff as the rider slides
Cuff slider that can be moved in the direction
A cuff wrapping device for a finger-type blood pressure monitor, comprising:
By operating the material, the cuff slider is moved to the inner diameter of the cuff.
So that it can be displaced in the direction to set
It is characterized by having done.

[0005]

[Function] When operating the slider to wind the cuff around the finger, press the button which is the operation member to release the fixing mechanism by the stopper and the locking claw and displace the cuff slider by a certain amount, Preset so that is smaller. When the cuff is wrapped around the finger and the hand is released from the slider and button, the button rises and the slider is fixed to the body, and the cuff slider returns to the original position by the preset amount on the slider, slightly expanding the inner diameter of the cuff Works in a similar manner.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1, 3, and 4 are cross-sectional views of main parts of an embodiment of the present invention, and FIG. 2 is an enlarged view of main parts of the embodiment of the present invention as viewed from inside a case. A slider top 10 is fixed to an upper part of the slider 1 slidably provided on the case 11. At a substantially central portion of the slider 1, there is provided a button 2 which is an operation member that can be smoothly moved in the vertical direction between the slider 1 and the slider top 10. Further, a coil spring 5 is mounted in a gap between the button 2 and the slider 1 to urge the button 2 toward the slider top 10. Also, cuff slider 3
Is set to be slidable on the slider 1 and is arranged so as to be able to engage with the tip of the button 2. Further, a tip (not shown in FIG. 2) of a cuff 8 is fixed to the cuff slider 3. Convex portions 3a, 3 of cuff slider 3
b, 3c and 3d prevent the cuff from coming off the cuff slider 3. The engaging portion of the cuff slider 3 with the tip of the button 2 forms a slope 9. When the button 2 is depressed, the tip of the button 2 presses the slope 9 of the engaging portion with the cuff slider 3. The rider 3 is displaced in the direction of arrow A, and the cuff 8 can be preset in a direction to reduce the inner diameter of the cuff by a certain amount.
Further, a locking claw 4 is fixed to the slider 1, and the locking claw 4 constitutes a fixing mechanism for engaging the rack 6 to fix the slider 1 to the case. A stopper 7 is fixed near the lower end of the button 2.

As shown in FIG. 1, when the button 2 is not depressed, the stopper 7 is located between the locking claws 4, and the ends 4a and 4b of the locking claw 4 come close to the stopper 7 to close. I have. For this reason, the displacement of the locking claw 4 is hindered, so that the slider 1 cannot move. As shown in FIG. 4, when the button 2 is pressed down, the locking claw 4 and the stopper 7 separate, and the locking claw 4 can be displaced.
Sliding is also possible. When measuring the blood pressure, insert a finger into the cuff storage portion 11a in the case 11, depress the button 2 to release the engagement between the stopper 7 and the locking claw 4, and preset the cuff slider 3 by a certain amount, and the entire slider 1 Slide in the direction to reduce the inner diameter of the cuff. Release the button from button 2 when you have finished wrapping the cuff around your finger. At this time, the button 2 is returned upward by the elastic force of the coil spring 5, and the locking claw 4 and the stopper 7 are engaged, thereby preventing the slider 1 from moving. The cuff slider 3 is pulled by the cuff 8 receiving a force in the direction of arrow B to increase the inner diameter due to the elasticity of the tightened finger, and returns by a preset amount, and releases the tightened finger by an appropriate amount. The preset amount is preferably about 1 to 3 mm. This avoids over-tightening of the finger and the cuff is properly wrapped.

[0008]

As described above, the cuff wrapping device for a finger-type blood pressure monitor according to the present invention comprises: a case body having a finger insertion portion;
A cuff that is housed in the finger insertion portion of the case body, wherein
A slider slidable on the case body, and the slider
To secure the slide to any sliding position on the case body.
And one end of the cuff is connected
Then, as the slider slides, the inside of the cuff
A cuff slider that can move in the direction to increase or decrease
A cuff wrapping device for a finger-type sphygmomanometer including a working member,
By operating the operation member, the cuff slider is moved to the
Displaceable in the direction to set the inner diameter of the cuff smaller by a certain amount
With such a configuration , the cuff is not wound with an excessively strong force, and the finger is not excessively pressed. Furthermore, since the cuff can be wound around the finger in a favorable state, the reliability of blood pressure measurement can be improved. Another advantage is that it can be manufactured at low cost because of its simple configuration.
