DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic sound augmentation case which is used by being attached to an electronic thermometer.

[0002]

2. Description of the Related Art An electronic thermometer, which has a probe for temperature measurement at its tip and digitally displays a body temperature measured via the probe on a liquid crystal display unit, has become widespread.

The temperature measurement by the electronic thermometer is performed for a certain period of time (for example, about 1 minute), and when the temperature measurement is completed, an electronic sound is emitted to notify the user. As a sound source that emits an electronic sound, for example, a buzzer plate is used.

By the way, such an electronic thermometer, particularly an electronic thermometer used in a medical institution such as a hospital, requires a waterproof function because it performs cleaning, disinfection, and the like. Therefore, the casing of the electronic thermometer has a closed structure. Has become.

[0005] Therefore, there is a problem that the electronic sound (buzzer sound) emitted from the sound source is blocked by the casing having the closed structure, and the volume cannot be sufficiently increased.

[0006] The volume of the electronic sound of the electronic thermometer may be insufficient depending on the usage form and the user of the electronic thermometer. For example, when an electronic thermometer is put in the armpit to measure body temperature, it may be difficult to hear the electronic sound depending on the insertion depth when the electronic thermometer is pinched in the armpit or the condition of the clothes worn. In addition, it may be difficult for a person whose hearing has declined due to the elderly to hear the electronic sound.

[0007] The oscillation frequency of the buzzer is changed.
It is also conceivable to address this problem by changing the sound source itself to a high-performance one. But even in this case,
There is a limit to the increase in volume, and there are also problems such as an increase in the size of the electronic thermometer and an increase in manufacturing cost.

[0008]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an electronic sound amplifying case according to the present invention.

FIG. 1 shows a first example of the electronic sound amplifying case of the present invention.
FIG. 2 is a perspective view showing the embodiment, and FIG. 2 is a sectional side view of the electronic sound amplifying case shown in FIG. As shown in these figures, the electronic sound augmentation case 1 of the present invention is used by being mounted on an electronic thermometer 20.

The electronic thermometer 20 has a tip portion 21 having a metal probe for temperature measurement.
A rear end 22 having a cap required for assembly is provided at a position opposite to the longitudinal direction.

The electronic thermometer 20 has a sound source 3 inside.
For example, a buzzer plate is stored as 2.

A display 23 for displaying the measured body temperature is provided on the upper surface (front surface) of the electronic thermometer 20 and at a position between the front end 21 and the rear end 22. The display unit 23 includes a liquid crystal display element that displays the measured body temperature value using liquid crystal (for example, a display such as “36.8 ° C.”) and a transparent window member that covers the liquid crystal display element.

The electronic sound augmenting case 1 is formed of a housing having an approximately rectangular parallelepiped outer diameter. The electronic sound amplifying case 1 has a pair of upper wall 2 and lower wall 3 facing each other, a pair of side walls 4 and 5 facing each other, and a rear wall 6. Upper wall 2 and lower wall 3
, The side walls 4, 5 and the rear wall 6 are orthogonal to each other. The front end side of the electronic sound amplifying case 1 is open to form an opening 7 into which the rear end 22 of the electronic thermometer 20 can be inserted.

The thickness of the walls of the housing, that is, the upper wall 2, the lower wall 3, the side walls 4, 5, and the rear wall 6 is not particularly limited, but is practically about 0.2 to 3.0 mm. Is preferred.

A space 8 is formed inside the electronic sound amplifying case 1 so as to accommodate the rear end 22 of the electronic thermometer 20. Circular holes 9, 10 and 11 are formed in the upper wall 2, the side wall 4 and the rear wall 6, respectively, so as to penetrate the wall. Thereby, the space 8 and the outside communicate with each other through the holes 9, 10, and 11. Such holes 9, 10, 1
By providing 1, the electronic sound (such as a buzzer sound) emitted from the sound source 32 and propagated to the rear end portion 22 reverberates (resonates) in the space 8 and goes out of the housing through the holes 9, 10, and 11. Released.

The holes 9, 10 and 11 are formed on three mutually orthogonal walls (upper wall 2, side wall 4 and rear wall 6). Thereby, the electronic sound is uniformly emitted in the other direction, and the electronic sound can be heard from any position or direction. Also, even if one or two of the holes 9, 10, 11 are closed, an electronic sound is emitted from the remaining holes and can be heard.

The respective opening areas of the holes 9, 10 and 11 is not particularly limited, usually, preferably about 7～60Mm ^2, and more preferably ² about 30 to 50 mm.

If the opening area is too small, it is difficult for the reverberation sound to be emitted to the outside of the electronic sound augmentation case 1, and if the opening area is too large, the echo itself is less likely to occur inside the electronic sound augmentation case 1.

In the illustrated embodiment, the holes 9, 10, 1
The shape of 1 is circular, but is not limited thereto, and may be any shape such as a triangle, a rectangle, and an ellipse.
Further, the position and the number of holes to be formed are not limited to those illustrated.

The electronic sound amplifying case 1 has positioning means for determining a positional relationship with the electronic thermometer 20 when the electronic sound thermometer 20 is mounted on the electronic thermometer 20. That is, the positioning means is constituted by the convex portion 12 formed to protrude from the inner surface of the lower wall 3.

As shown in FIG. 2, when the rear end 22 of the electronic thermometer 20 is inserted into the space 8 through the opening 7 of the electronic sound amplifying case 1, the insertion depth reaches a predetermined depth. At this time, the rear end of the electronic thermometer 20 engages with the protrusion 12 and stops at that position. Thereby, the positional relationship of the electronic thermometer 20 with respect to the electronic sound increase case 1 is determined. When this state is referred to as “a state of being attached to the electronic thermometer 20”, in a state of being attached to the electronic thermometer 20, the electronic sound emitted from the sound source is located between the rear end face of the electronic thermometer 20 and the inner surface of the rear wall 6. A resonance space is formed in which can resonate. Therefore, the electronic sound emitted from the sound source is increased in this resonance space, and the holes 9,
It is released to the outside from 10 and 11.

When mounted on the electronic thermometer 20, the volume of the resonance space is preferably about 700 to 3600 mm ³ . Further, it is more preferably about 1600 to 2700 mm ³ , and the effect of increasing the electronic sound is large.

The electronic sound augmentation case 1 has a shape and dimensions so as not to cover the body temperature display section 23 of the electronic thermometer 20 when mounted on the electronic thermometer 20.
Thus, after the body temperature is measured, the body temperature displayed on the body temperature display unit 23 can be viewed without removing the electronic sound increase case 1 from the electronic thermometer 20.

The electronic sound augmentation case 1 has such a symmetry that the electronic thermometer 20 can be worn regardless of whether the electronic thermometer 20 is on the front or back. That is, FIG.
In, even when the electronic thermometer 20 is turned upside down (front and back), the electronic sound increasing case 1 can be mounted.
Thus, when the electronic sound increasing case 1 is mounted on the electronic thermometer 20, the mounting operation can be performed without considering the vertical (front and back) directions of the electronic thermometer 20, and the operability is excellent.

The constituent material of the housing of the electronic sound enhancement case 1 is as follows.
The material is not particularly limited, and a material that is hard and easily resonates is preferable, and examples thereof include various resin materials, various metal materials, and various ceramic materials.

As the resin material, for example, polycarbonate, acrylic resin, acrylonitrile-butadiene-styrene copolymer (ABS resin) and the like can be used.

As the metal material, for example, an Fe alloy such as stainless steel, Cu or Cu alloy, Al or A
l-based alloys and the like.

Examples of the ceramic material include alumina, apatite, and aluminum nitride.

With the electronic sound increasing case 1 attached to the electronic thermometer 20, the probe 21 of the electronic thermometer 20 is sandwiched, for example, under the armpit, and measurement of body temperature (temperature measurement) is started. After a lapse of a predetermined time (for example, about 1 minute), an electronic sound is emitted from a sound source 32 built in the electronic thermometer 20 to notify the end of the temperature measurement. This electronic sound reverberates (resonates) in the space 8, and its volume (sound pressure) is increased, and the holes 9, 10,
11 to the outside of the electronic sound augmentation case 1. The body temperature measurer hears this electronic sound and knows that the temperature measurement has been completed. Then, while the electronic sound increasing case 1 is attached to the electronic thermometer 20, the measured value of the body temperature displayed on the display unit 23 can be viewed.

The electronic sound that can be heard by the body temperature measurer is smaller than the case where the electronic sound increase case 1 is not attached to the electronic thermometer 20.
