Description

  The present invention relates to a storage unit for a button-type battery and a medical electronic device including the same.

Small and lightweight button-type batteries are used in various electronic devices, and many examples are used in medical electronic devices.
For example, in an electronic thermometer that measures body temperature, a button-type battery is used as a power source for calculating and displaying the body temperature (see Patent Document 1). In addition, a biological information collecting apparatus has been proposed that allows a patient to read biological information such as body temperature with a device such as an electronic thermometer at home or the like (see Patent Document 2). The biological information collection device is also brought down in size and thickness because it is brought to a hospital, for example, and a button-type battery is used as its power source.

  Such a button-type battery is generally replaced because of its low power capacity, and therefore, the battery is structured to be detachable. For example, in the case of Patent Document 1, as shown in FIGS. 5 and 6, a concave portion SP in which a button-type battery is detachably accommodated and a lid member 24 that covers the opening of the concave portion SP are provided. doing. The concave portion SP has a wall surface portion 30R disposed adjacent to the outer peripheral surface of the button type battery, and prevents the button type battery from falling off. And when replacing a button type battery, the cover member 24 is removed and the button type battery accommodated in the recessed part SP is taken out.

JP 2013-65424 A Japanese Patent No. 3759784

However, in the conventional storage part for the button-type battery including the concave part SP and the lid member 24, since the button-type battery is housed deeply in the concave part, it is difficult to remove the button-type battery and the replacement work is easy. is not. In Patent Document 1, there is a notch in the wall surface portion 30R surrounding the button-type battery, and a tool with a thin tip such as a toothpick is inserted from there to make it easier to remove the button-type battery compared to a general attachment / detachment structure. However, it cannot be said that it is still easy to remove, especially for medical electronic devices handled by elderly people and nurses.
SUMMARY OF THE INVENTION An object of the present invention is to provide a battery storage unit and a medical electronic device that can easily replace a button-type battery.

  The subject includes a battery accommodating portion for accommodating a button-type battery, and a lid member capable of opening and closing the battery accommodating portion, and the lid member includes the battery accommodating portion in the closed state. The button-type battery can be attached to and detached from the inner surface facing each other, and the inner surface of the lid member is adjacent to the button-type battery mounting region and is located in each of the diametrically opposite regions of the mounting region. A claw that is formed integrally with each of the two guide portions for guiding the button-type battery and the two guide portions, and holds the button-type battery so as to be pressed from above. And at least a protrusion lower than the thickness of the button-type battery in the direction of sliding the button-type battery in the periphery of the attachment area, and the protrusion is on the attachment area side, Wearing It is solved by the housing portion of the button-type battery, wherein a slanted surface which is adapted to gradually increase the height is formed with distance from the band.

According to the above configuration, the battery housing portion for housing the button-type battery and the lid member capable of opening and closing the battery housing portion are provided, and the lid member faces the battery housing portion in the closed state. A button-type battery is detachable on the inner surface. Then, if the button-type battery is attached to the lid member, the button-type battery can be detached from the battery housing portion as the lid member opens and closes with respect to the battery housing portion. Therefore, even if the battery accommodating portion has a deep concave shape for accommodating the button type battery, the button type battery can be easily taken out from the concave portion.
Here, on the inner surface of the lid member, there are two guide portions that are erected in each of the diametrically opposite regions of the attachment region adjacent to the attachment region of the button type battery. Therefore, when the button-type battery is mounted on the lid member, for example, if the button-type battery is pushed so as to slide in one direction substantially orthogonal to the imaginary line connecting the two guide parts, the guide part 2 guides the battery. It is easily arranged between the guide portions at the positions, that is, in an appropriate mounting region of the button type battery.
If a button-type battery is placed between the two guide parts, the button-type battery is pressed from above and fixed to the lid member by two claw parts formed integrally with the two guide parts. can do.
Also, to remove the button-type battery from the lid member, the button-type battery can be slid in one direction as described above, and if the button-type battery is pressed and kept slid, the button-type battery is held from above. Since it leaves | separates from the position of a part, the latching state by the said nail | claw part is cancelled | released and it can remove from a cover member.
The above “pressing from above” is intended to prevent the button-type battery from being detached from the lid member, and the button battery need not be pressed against the inner surface of the lid member as long as the button-type battery is not detached. The “two guide portions” means that guide portions are formed in regions opposite to each other in the diameter direction of the button-type battery, and a plurality of guide portions are formed in each portion. It does not exclude what is done.

  Further, the inner surface of the lid member has a protrusion that is at least around the button-type battery thickness in the sliding direction around the button-type battery mounting region. For this reason, when removing the button-type battery from the lid member, if the button-type battery is slid by pushing with a finger while being guided by the guide portion as described above, the button-type battery hits the projecting portion with a short height, Slide. Therefore, for example, even if the lid member is small and there are walls, ribs, or the like at the edge thereof, the button-type battery can be removed from the lid member by overcoming them.

In addition, the projecting portion is formed with an inclined surface that gradually increases in height as the distance from the mounting area increases.
Therefore, when removing the button-type battery, if the button-type battery in the mounting area is pushed and slid toward the protrusion, the button-type battery can be easily lifted while being guided by the inclined surface of the protrusion. The button battery can be easily replaced.

Preferably, the battery accommodating portion has a connection terminal portion that comes into contact with an electrode disposed on a main surface of the button-type battery, and the main surface of the button-type battery is on an inner surface of the lid member. When it is directed, the button-type battery cannot be mounted by hitting the claw portion.
Therefore, when the electrode surface to be mounted on the front surface of the button type battery is mistakenly directed to the inner surface of the lid member, the button type battery cannot be attached to the lid member, and erroneous mounting can be prevented.

In addition, the above-described problem is a medical electronic device that uses a button-type battery as a power source, and includes a battery housing portion for housing the button-type battery, and a lid member that can close the battery housing portion so as to be opened and closed. The button member is attachable to and detachable from the inner surface of the cover member facing the battery housing portion in the closed state, and the button battery is attached to the inner surface of the cover member. Two guide portions for guiding the button-type battery so as to be slidable in one direction by being erected in each of the diametrically opposite regions of the mounting region adjacent to the region; and A claw portion that is integrally formed with each of the guide portions and that locks the button-type battery so as to be pressed from above, and at least the button-type battery in the sliding direction around the mounting region. Thickness And low projections are solved by a medical electronic device is formed than.
Therefore, even a medical electronic device using a button-type battery, which is likely to become a user by a weak person such as an elderly person or a viewer, and the frequency of battery replacement is relatively high, The button type battery can be easily replaced by using the detachable structure.

  As described above, according to the present invention, it is possible to provide a battery storage unit and a medical electronic device that can easily perform replacement work of a button-type battery.

It has portions 34 and 35 and a substantially 1/4 circumferential portion 36.

  5 is a plan view showing the inner surface side of the lid member 30 shown in FIG. 4, and FIG. 6 is a perspective view showing the inner surface side of the lid member 30 shown in FIG. In FIG. 5, the button type battery BA is not installed, and FIG. 6 shows the state where the button type battery BA is installed. 5 is an enlarged perspective view of a protrusion 41 to be described later, and the figure surrounded by a two-dot chain line in FIG. 5 is a cross-sectional view taken along line AA in FIG. Further, the “inner surface” referred to here is a surface opposite to the outer surface on which the lid member 30 shown in FIG. 4 is represented, and the battery housing in a state where the battery housing portion 101 of FIG. It is a surface facing the part 101.

Here, before explaining the structure of the lid member 30, the structure example of the button-type battery BA shown in FIG. 6 will be briefly described. The button-type battery BA is also called a coin-type battery, and many are primary batteries. A lithium battery, an alkaline manganese battery, or the like. The button type battery BA has a thin cylindrical shape as a whole, and includes a plus electrode 29A, a minus electrode 29B, and an insulator 29C. The plus electrode 29A has a circular bottom surface 29D arranged to face the inner surface 38 of the lid member 30, and an outer peripheral side surface 29E electrically connected to the bottom surface 29D. In such a button-type battery BA, when the negative electrode 29B arranged on the main surface is directed upward as shown in FIG. 6, a step portion (upward step portion in the figure) 29F is provided substantially at the position of the insulator 29C. Have.
As types, there are CR1620, CR2016, CR2025, CR2032, CR2354, CR2453, CR3032 and the like depending on the size (diameter) and thickness. Here, the upper two digits indicate the diameter (mm), and the lower two digits indicate the thickness. For example, CR1620 has a diameter of 16 mm and a thickness of 2.0 mm, and CR2032 has a diameter of 20 mm and a thickness of 3.2 mm. In the present specification, CR 2032 will be described as an example.

As shown in FIG. 5 and FIG. 6, the lid member 30 has an attachment portion 60 for fixing the battery housing portion 101 (see FIG. 8) on the casing side to be described later when the lid member 30 is closed. The mounting portion 60 has a substantially cross-sectionally L-shaped claw 61 facing downward in FIG. 6, and this claw 61 is elastically deformed, and the mounting portion 70 of the container-type back member 22 of FIG. And can be engaged. Thereby, as shown in FIG. 4, the lid member 30 is detachably attached to the housing 20 so as to close the notch 90 of the container-type back surface member 22.
As shown in FIGS. 5 and 6, the lid member 30 has a flat plate portion 37, and linear wall portions 34, 35 and a substantially ¼ circumference on the edge of the flat plate portion 37. The wall portion 36 stands on the side where the button type battery BA is attached. These wall portions 34, 35, and 36 increase the rigidity of the flat plate portion 37, and the side portions 25 and 27 of the housing 20 (back surface member 22) with the notch portion 90 closed as shown in FIG. 4. A part of the corner 22A is configured.
6 is an extension line of an imaginary line connecting protrusions 40 and 41, which will be described later, and is disposed in the vicinity of the protrusion 40, and the attachment part 60 and the protrusion 40 are connected to each other. The plate thickness D <b> 1 in the intermediate portion 37 a is formed to be thinner than the other portions of the flat plate portion 37. This reduces the influence of the stress generated by the deformation of the mounting portion 60 on the protruding portion 40 and prevents the button-type battery BA from being detached from the lid member 30 when the lid member 30 is attached to or detached from the housing 20. It is preventing.

A circular positioning recess 39 is formed on the inner surface 38 of the flat plate portion 37 shown in FIGS. This positioning recess 39 is a button battery BA mounting region (an appropriate region to be mounted), and has a planar shape corresponding to the mounting region. (In the figure, the diameter of the recess 39 is substantially the same as the diameter of the circular bottom surface 29D of the button-type battery BA). When the button-type battery BA is placed in the recess 39, which is the mounting area for the button-type battery BA, the circular bottom 29D and the outer peripheral side 29E of the positive electrode 29A are partially inserted into the button-type battery BA. Is positioned with the negative electrode 29B facing up.
The recess 39 has a very shallow depth. In the case of the figure, the depth is about 0.2 to 0.5 mm and less than 1 mm. In combination with the claw portions 40B and 41B described later, the button-type battery BA is provided. The lid member 30 is positioned and regulated (it is freely rotatable in the circumferential direction, and the vertical direction is regulated by the claw portions 40B and 41B and the recess 39).

Further, on the inner surface 38 of the flat plate portion 37, two projecting portions 40 and 41 projecting upward with the inner surface 38 facing upward and the button-type battery BA mounted thereon are, for example, elastic thermoplastic. It is made of styrene resin (high impact styrene, ABS resin, etc.), which is a resin, and has a required elastic force. Antibacterial properties can be obtained by adding about 1.5% by weight of a silver compound such as silver zeolite, silver silica gel, and zirconium phosphate silver compound as an additive.
The projecting portions 40 and 41 facing each other have a function of positioning and regulating the button-type battery BA with respect to the lid member 30 (movable in the circumferential direction), and a guide function serving as a guide when the button-type battery BA is attached and detached. It is for making it exhibit, and has guide parts 40A and 41A and claw parts 40B and 41B.
The claw portions 40B and 41B regulate the positioning of the button type battery BA in the lid member 30 in the vertical direction, and have a height of about 0.5 to 1.0 mm in the radial direction, and any one of them functions.

The guide portions 40A and 41A are adjacent to each other along the circumference of the positioning concave portion (mounting region) 39. When the button type battery BA is mounted, the guide portions 40A and 41A are adjacent to the outer peripheral side surface 29E of the button type battery BA. Two cells S1 and S2 are provided so as to rise substantially perpendicularly in each of the regions S1 and S2 on the opposite side (180 ° opposite side) in the diameter direction DL of the type battery BA. That is, the guide portions 40A and 41A are arranged so as to face each other along the diameter direction DL of the button type battery BA with the button type battery BA interposed therebetween.
Thereby, the button-type battery can be passed only in the sliding direction SL substantially perpendicular to the imaginary line (line in the diameter direction DL) connecting the guide portion 40A and the guide portion 41A. Accordingly, when the user attaches the button type battery BA to the lid member 30, the user pushes the button type battery BA to slide between the guide part 40A and the guide part 41A and is guided to the guide parts 40A and 41A. The button-type battery BA can be disposed in the positioning recess 39. Further, when the button-type battery BA is removed from the lid member 30, it can be easily removed by pressing the button-type battery BA with a thumb or the like with a force of about 300 to 500 gf so that the button-type battery BA is similarly slid in the sliding direction SL.

In the guide portions 40A and 41A of the present embodiment, the surfaces 18 facing each other (see the diagram surrounded by the one-dot chain line in FIG. 5) are in contact with a part of the outer peripheral side surface 29E of the button type battery BA as shown in FIG. It is also designed to be pinched.
The guide portions 40A and 41A shown in FIGS. 5 and 6 have a required width W (preferably about 1/13 of the circumferential direction) along the circumferential direction of the outer peripheral side surface 29E of the button-type battery BA. The facing surface 18 is curved corresponding to the outer peripheral side surface 29E of the button type battery BA, thereby increasing the degree of clamping. As described above, even when the guide portions 40A and 41A have the required width W, they have the required elastic force in the direction of the imaginary line (the direction DL in the figure) that connects the guide portions 40A and 41A. In this manner, the guide portions 40A and 41A can sandwich the button type battery BA and slide the button type battery BA in the sliding direction SL.

The claw portions 40B and 41B are portions for mainly exerting the fixing function as described above, and are formed integrally with the two guide portions 40A and 41A, respectively, in the diameter direction DL of the button type battery BA. Arranged in the opposite regions S1 and S2. And as shown in FIG. 6, the nail | claw parts 40B and 41B are locked so that the button type battery BA may be pressed from the top. Note that “pressing from above” does not mean that the button-type battery BA is strongly pressed against the inner surface 38 by the claw portions 40B and 41B, but the inner surface 38 from which the button battery BA is detached from the lid member 30. The purpose is to prevent floating from.
In the case of the figure, the claw portions 40B and 41B are formed so as to protrude substantially horizontally toward the inside from the upper end portions of the guide portions 40A and 41A so as to face each other. And the nail | claw part 40B, 41B hooks on the upper edge part of the outer peripheral side surface 29E of the button type battery BA, ie, the step part 29F. Thereby, in this embodiment, the situation where the button-type battery BA pops out from the positioning recess 39 is prevented. At this time, in a state where the button-type battery BA is pressed by the claw portions 40B, 41B, the button-type battery BA may float slightly from the inner surface 38 of the lid member 30 within a range in which the button-type battery BA does not come out of the recess 39.
Note that the opposing surfaces 19 (see the diagram surrounded by the one-dot chain line in FIG. 5) of the two claw portions 40B and 41B are curved substantially corresponding to the ring-shaped insulator 29C of the button-type battery BA. .

Further, as shown in FIGS. 5 and 6, on the flat plate portion 37 of the inner surface 38 of the lid member 30, there is a slide around a positioning recess (appropriate mounting area for the button type battery BA) 39. A protrusion 42 is formed on one side in the direction SL.
The protrusion 42 has a lift-up function for lifting the slid button-type battery BA when the button-type battery BA is removed so that the button-type battery BA does not completely slide against the button-type battery BA. The height H is at least lower than the thickness of the button-type battery BA.
Further, the protrusion 42 is preferably disposed adjacent to the outer peripheral side surface 29E of the attached button battery BA, and as a result, the button battery BA is not subject to any external force that intentionally pushes the button battery BA. It is possible to exhibit the function of a stopper that prevents a situation in which the user slides in the sliding direction SL beyond the mounting area.
In order to satisfy such lift-up function and stopper function, the height H of the protrusion 42 is about 1 to 2 mm (that is, about 1/3 to 1/2 of the thickness of the button type battery BA used). The width W2 is preferably about 1 to 2 mm. That is, if the height H of the protrusion 42 exceeds 2 mm, the lift-up function is obstructed when the button-type battery BA is removed from the positioning recess 39, and if the height H is less than 1 mm, the slide-type battery BA slides when the button-type battery BA is mounted. The function as a stopper in the direction SL is reduced.
If the width W2 exceeds 2 mm, the lift-up function is obstructed when the button-type battery BA is removed from the positioning recess 39, and if it is less than 1 mm, it serves as a stopper in the sliding direction SL when the button-type battery BA is mounted. The function of is reduced.
In addition, the protrusion part 42 of this embodiment is continuous from the inner peripheral side surface 39a of the said recessed part 39 along the circumference of the recessed part 39 for positioning, as shown in the figure enclosed with the dashed-two dotted line of FIG. It is formed to stand up.

The projecting portion 42 has an inclined guide portion 43 and a flat top portion 44.
The inclined guide portion 43 is an inclined surface that gradually increases in height as it moves away from the button-type battery BA on the side of the attached button-type battery BA (positioning recess 39 side). When the button-type battery BA is removed and is slid with a thumb or the like in the SL direction toward the protrusion 42, the inclination angle θ that can get over the wall 34 at the edge of the lid member 30 is 40 degrees to 50 degrees, preferably It is preferable to set the angle to 45 degrees, so that the button-type battery BA can be easily removed simply by pushing the button-type battery BA in the SL direction toward the protrusion 42. If this inclination angle θ exceeds 50 degrees, it will interfere with an easy lift-up function when the button-type battery BA is removed from the positioning recess 39, and if it is less than 40 degrees, it will slide when the button-type battery BA is mounted. The function as a stopper in the direction SL is reduced.
The protrusions 42 of the present embodiment are formed only on one side in the sliding direction SL with reference to the button type battery BA, but the present invention is not limited to this form, and the other side in the sliding direction SL. A protrusion may be provided in S3. In this case, it is preferable that the protrusion provided on the S3 side has substantially the same shape so as to have an inclined surface on the mounting region side, like the protrusion 42. As a result, the degree of fixing can be increased by sandwiching the button-type battery BA between the protrusions facing each other, and the button-type battery BA can be easily mounted while being guided by the inclined surface.
