Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an electronic sphygmomanometer having a cuff housing.

[Problems to be Solved by Prior Art and Invention]

As a conventional technique, electronic blood pressure monitors shown in FIGS. 10 and 11 are known.

In the conventional example shown in FIG. 10, a cuff case 3 accommodating a band-shaped cuff 2 and a rubber tube (not shown) is provided in the rear part of the sphygmomanometer main body 1, and a lid 4 is provided in the peripheral edge part of the opening of the cuff case 3. It is provided so as to be openable and closable via the hinge 5 provided.

The conventional example shown in FIG. 11 is an electronic sphygmomanometer shown in Japanese Utility Model Application Laid-Open No. 64-19403, in which a sphygmomanometer body 6 and a cuff case 7 capable of accommodating the cuff 2 are connected via a hinge 8. The structure is such that the cuff 2 and the like are put in and taken out by opening 7 upward.

In any of these electronic blood pressure monitors, the vertical cross section of the cuff cases 3 and 7 is U-shaped, and to remove the cuff, insert your hand between the cuff and the cuff case, bend your fingertips, and remove the cuff. There is a problem in that the ease of taking out is not taken into consideration because it has to be taken out by pushing it up toward the opening or by grasping the entire cuff.

In addition, recently, the volume occupied by the cuff case has been reduced due to the demand for compaction of the entire electronic sphygmomanometer. In this case, since the flexible cuff is compressed and accommodated in the cuff case, the cuff can be accommodated after or at the time of accommodation. Expands due to self-restoration. And a cuff case with a U-shaped vertical section
In 3 and 7, since the opposing side walls forming the cuff case are parallel to each other, the expanded cuff presses the opposing side wall in the vertical direction, and a large pressure contact force acts between the cuff and the cuff case forming side wall. Therefore, when the cuff 2 is put in and taken out of the cuff cases 3 and 7, the pressure contact force between the cuff and the side wall forming the cuff case acts as a load, and as a result, it is difficult to store the cuff in the cuff case or it is difficult to take out the cuff. is there.

Further, in the conventional example shown in FIG. 11, there is also a problem that the sphygmomanometer body 6 becomes large due to the structure in which the cuff case is inverted.

The present invention has been made in view of the above-mentioned problems of the prior art,
An object of the present invention is to provide an electronic sphygmomanometer that includes a cuff and a cuff case in which a rubber tube can be easily taken in and out, and is compact as a whole sphygmomanometer.

[Means for Solving the Problems]

In order to achieve the above object, in the electronic sphygmomanometer according to claim (1), an electric component is mounted on the front surface of the rear casing, the front casing is assembled on the front surface of the rear casing, and the upper casing having a display portion is provided. The sphygmomanometer case is configured by being integrated with the front and rear casings, and a recess is formed on the rear surface side of the rear casing to have a vertical cross section of approximately V.
The C-shaped cuff case is pivotally supported on the rear casing so that it can project and retract into the recess.When the cuff case is projected from the recess, the cuff case opening opens rearward of the sphygmomanometer case, allowing the cuff to be taken in and out. When the cuff case is immersed,
The cuff case opening is closed so that the cuff can be stored in the sphygmomanometer case.

Further, in claim (2), the volume of the cuff case is made smaller than the volume of the cuff that is wound or folded.

Further, in claim (3), the component mounting portion is formed to project at the same angle in the front direction on the surface of the electrical component device of the rear casing.

Further, in claim (4), stopper means for holding the cuff case in the recessed state is provided between the cuff case and the rear casing.

[Action]

In claim (1), when the cuff case is rotated around the shaft supporting portion and protrudes from the recess, the cuff case opening opens rearward of the sphygmomanometer case, and the cuff can be taken in and out of the cuff case. Since the cuff case has a substantially V-shaped vertical cross section and the inside of the cuff case is widened toward the opening, for example, when a hand is inserted between the cuff and the cuff case, the cuff is pushed up along the inner surface of the cuff case, and the opening is opened. Since it is pushed toward, it will be in a state where it can be naturally grasped by the hand, and the cuff can be taken out easily. Further, since the inside of the cuff case expands toward the opening, it is easy to accommodate the cuff. Then, when the cuff case accommodating the cuff is rotated around the pivotal support portion and retracted into the recess, the cuff case opening is closed and the cuff is accommodated in the sphygmomanometer case.

Further, the cuff case is pivotally supported on the back side of the sphygmomanometer case so that it can be projected and retracted with respect to the back side, and the portion for accommodating the cuff is provided not on the front side or the top side of the sphygmomanometer case, but on the back side.

Further, in claim (2), since the volume of the cuff case is smaller than the volume of the cuff that is wound or folded, the cuff housed in the cuff case must be a single cuff when the cuff case opening is open. The part is in a state of protruding from the cuff case opening.

Further, in claim (3), the component mounting portions projecting at the same angle in the front direction on the front surface of the rear casing enable the components to be mounted from the same direction.

Further, in claim (4), since the stopper means for holding the cuff case in the recessed state is provided between the cuff case and the rear casing, the cuff case can be arbitrarily projected or retracted into the recessed portion. You can

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

The figure is a vertical cross-sectional view showing a state in which the cuff is housed in the electronic sphygmomanometer, FIG. 3 is a perspective view showing the state in which the cuff case is attached to the recessed area of the electronic sphygmomanometer, and FIG. 4 is the vicinity of the V-shaped corner of the cuff case. FIG. 5 is a front view showing the shaft support portion, FIG. 5 is a sectional view taken along line VV shown in FIG. 4, and FIG. 6 is an exploded perspective view of the electronic blood pressure monitor.

In these figures, a display part 12 is provided on the upper surface of a hollow container-shaped synthetic resin sphygmomanometer case 11 in which electrical components are installed, and a synthetic resin cuff case 60 capable of accommodating a cuff is a case.
The electronic sphygmomanometer 10 is pivotally supported on the back surface of the case 11, and the cuff case 60 is capable of projecting and retracting with respect to the back surface of the case 11 by rotating the cuff case 60 around the axis supporting portion. Reference numeral 2 is a flexible cuff that is in the form of a band and includes an air reservoir, is connected to the electronic sphygmomanometer 10 via the rubber tube 9, and is housed in the cuff case 60 when not in use. Reference numeral 9a is an air plug provided at the end of the rubber tube 9,
Reference numeral 55 is a connection hole (see FIGS. 3 and 6) provided in the electronic sphygmomanometer 10, and is an air socket to which the air plug 9a is connected.
83 is provided in the connection hole 55.

As shown in FIG. 1 and FIG. 2, the sphygmomanometer case 11 has a front wall and a rear wall which protrude toward the front as they go upward, and the rear wall is made higher than the above walls, and a surface which passes through the central axis through the thick cylinder. The external shape is like a divided body cut into 8 equal parts.
For this reason, the upper surface can be grasped and carried without a handle. Further, the upper surface of the case on which the display unit 12 is provided is inclined forward by about 45 degrees so that the user can
The 12 displays are easy to read. Furthermore, switches are provided on the top of the sphygmomanometer case 11 to facilitate the switch operation with one hand. On the other hand, the back surface of the sphygmomanometer case 11 is engraved on the front side (inside the case).
In addition, the structure is such that the cuff case 60 having a substantially V-shaped vertical cross section can be completely accommodated. That is, the display portion is generally formed on the front surface and the top surface of the sphygmomanometer case that are easy for the user to see, but since the cuff case is housed on the back surface of the sphygmomanometer case, the display portion can be made large and the display portion formation position There is an advantage that there are few restrictions.

Reference numeral 14 is coupled to the rear wall of the sphygmomanometer case,
An engraved portion forming side wall which forms 50, an engaging hole 58 which is a support portion of the cuff case is formed in the engraved portion forming side wall 14. Reference numeral 68 is an engaging protrusion projecting near the V-shaped corners of the left and right side walls 60b of the cuff case 60. The engaging protrusion 58 is supported by the engaging hole 58 and is provided inside the sphygmomanometer case 11 within the shaft supporting portion 15 (see FIG. 2). reference)
The shaft support portion 15 has a good appearance without being exposed to the outside of the case 11. In this way, the cuff case 60 rotates around the shaft support portion 15 and protrudes from the cutout portion 50 and moves backward from the cutout portion 50 from the state where the cuff case 60 is retracted into the cutout portion 50 and the opening portion 61 is opened (see the solid line position in FIG. 2). It becomes a state in which it is greatly opened (see the phantom line position in FIG. 2). The state where the opening 61 is closed, that is,
When the cuff case 60 is completely accommodated in the electronic sphygmomanometer 10, the rear wall 60a of the cuff case is flush with the peripheral portion of the back wall of the sphygmomanometer case and forms a part of the rear wall of the sphygmomanometer case. As a result, the electronic blood pressure monitor 10 looks good.

Further, the side wall 14 for forming the engraved portion has a hollow double wall structure that opens to the front side (inside the case), as shown in FIGS. 3 and 6. Then, from the open end of the engraved part to the engaging hole
A guide groove 57 that extends horizontally to 58 is formed, and further, the depth of the guide groove 57 is the inner wall of the wall 14 (the wall where the engagement hole 58 is formed).
The engaging hole 58 and the guide groove 57 can be formed at the same time. That is, the engagement hole 58 can be formed at the same time when the back wall of the sphygmomanometer case is formed, and the troublesome post-drilling process is unnecessary.

The guide groove 57 is provided with a cuff case rotation restricting means. That is, as shown in FIGS. 3 to 5, the guide groove 57 is made wider than the engaging hole 58 and a vertical wall-shaped contact surface 57a is formed at the peripheral edge portion of the engaging hole 58. An arcuate convex portion 67 corresponding to the contact surface 57a is formed at the base of the engaging protrusion 68. For this reason, the cuff case 60
When is rotated to open, the end surface 67a of the convex portion 67 comes into contact with the contact surface 57a of the guide groove 57, and the cuff case 60 stops in a state (the virtual line in FIG. 2) in which the opening portion 61 is oriented somewhat toward the engraved portion. , The cuff does not fall from the cuff case, making it easy to put in and take out the cuff. Further, the slope 68 is formed on the engaging projection 68 on the cuff case side.
a is formed, and the engaging protrusion 68 is formed through the guide groove 57.
It can be smoothly slide-pressed into 8 and makes it easy to attach the cuff case 60 to the sphygmomanometer case 11.

The volume of the cutout portion 50, which is the accommodation portion of the cuff 2, is set to a size capable of accommodating the cuff 2 in a compressed state in cooperation with the cuff case 60, that is, the space occupied by the cuff accommodation portion is reduced, and the sphygmomanometer accordingly. The case, that is, the electronic blood pressure monitor 10 is downsized. On the other hand, the volume of the cuff case 60 is smaller than that of the engraved portion 50, and when the cuff case is opened (see the phantom line position in FIG. 2), the cuff 2 partially protrudes from the cuff case 60, and the cuff 2 can be immediately grasped. It is convenient to take out the cuff as it can be grabbed.

Further, since the cuff case 60 has a substantially V-shaped container in vertical section as described above, the inside of the case expands toward the opening side, and the cuff can be easily taken in and out. Also, when the cuff case is opened and the cuff 2 is in an uncompressed state, the cuff packed in the cuff case returns to its original state by the self-restoring force, so that the cuff bulges above the opening of the cuff case and the cuff 2 is held by hand. It becomes easy to grasp with.

A stopper mechanism is provided between the fluff case 60 and the peripheral edge portion 52 (see FIG. 3) of the cuff case, which automatically operates when the cuff case is closed and holds and holds the cuff case 60 in the closed portion 50 in the closed state.

The amount of movement of 63 is restricted by the width of the long hole 66 with which the knob 63b engages. A spring member 65a is interposed between the back surface of the hook of the stopper member 63 and the stopper presser 65, and the stopper member 63 is biased in a direction in which the hook 64 always projects from the upper edge of the cuff case rear wall 60a. Then, the hook 64 protruding from the upper edge of the cuff case rear surface wall 60a is engaged with the engagement hole 59 formed on the side of the cutout forming wall,
The cuff case 60 is kept closed. The hook 64 has a distal end portion having a wedge shape in a vertical cross section, which includes a sloped surface portion 64a and a flat surface portion 64c, so that the hook 64 can be smoothly engaged with the engagement hole 59. That is, the cuff case 60 is engraved
When it is attempted to immerse it in the hook 50, the hook slope 64a comes into contact with the cutout forming wall edge 52a (see FIG. 3) and slides, the spring member 65a is compressed, and the stopper member 63 is retracted.
The cuff case 60 enters the engraved portion 50. Then, when the cuff case 60 is sufficiently immersed in the engraved portion 50, the positions of the hook 64 and the engagement hole 59 are aligned, the stopper member 63 is pressed by the restoring force of the spring member 65a, and the hook 64 is engaged with the engagement hole. Engage with 59. After that, since the restoring force of the spring member 65a acts, the flat surface portion 64c of the hook catches on the peripheral edge portion of the engaging hole 59, and the hook 64 is held in the retaining state. in this way,
If you push the cuff case 60 into the engraved part 50, the stopper mechanism will automatically operate and the cuff case will be kept closed.
The cuff 2 put in the cuff case 60 is accommodated in the electronic blood pressure monitor 10 in a compressed state.

On the other hand, when the cuff case 60 is opened, the knob 63b is held and the stopper member 63 is pushed down to disengage the hook 64 from the engagement hole 59. The cuff case 60 rotates clockwise from the engraved portion 50 in FIG. Then, when the cuff case 60 is rotated with a little hand to assist, the cuff case 60 is then rotated by the weight of the cuff and the cuff case, the rotation is stopped at the position where the restricting means is present, and the cuff in the cuff case can be easily taken out.

Reference numeral 62 denotes a cutout portion formed from the side wall 60b to the back wall 60a of the cuff case 60, which is a rubber tube 9 extending to the cuff 2.
It is for inserting. On the other hand, a chamfered portion 67 for preventing a load from acting on the rubber tube 9 led out from the cutout portion 62 is formed at a position corresponding to the cutout portion 62 on the side wall 14 for forming the cutout portion. When using the cuff, cuff 2 and cuff case
When the rubber tube 9 is taken out from 60 and the cuff case is closed by inserting the rubber tube 9 into the cutout portion 62, the rubber tube 9 is put in a state of being passed through the hole formed by the cutout portion 62 and the chamfered portion 67. That is, the cuff case 60
