Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.

1 is a view illustrating a state in which a stethoscope plate of a stethoscope is inserted into a stethoscope sterilization apparatus according to a first embodiment of the present invention, and FIG. 2 is a side cross-sectional view showing a state before the stethoscope plate is inserted into the stethoscope sterilization apparatus of FIG. 1. .

Typically, the stethoscope 1 is provided with a stethoscope plate 15 for contacting the patient's body at one end of the Y-shaped tube 14 and the branch pipe 12 is provided at the other end of the tube. Branch pipe 12 is elastically supported in the direction tightened close to each other by a clip 13 installed on one end of the branch pipe 12, ear plug 11 that the doctor plugs into the other end of the branch pipe 12 Is installed.

Stethoscope sterilization apparatus 3 according to the present invention is a device for sterilizing and protecting the stethoscope plate 15 of the stethoscope 1 described above. The stethoscope sterilization apparatus 3 is formed in a substantially cylindrical shape so as to surround a circular stethoscope plate. The sterilization device 3 has a stethoscope plate accommodating portion 70 surrounded by an inner casing 50. The inner casing is formed in a concave shape with an open upper end, the entrance side of the concave space is provided with a stethoscope plate accommodating portion 70, and a substrate having an ultraviolet light emitting diode 40 (UV LED) mounted therein. 42) is installed. In one embodiment, the ultraviolet light emitted from the ultraviolet light emitting diode is deep ultraviolet light (DUV) having a peak wavelength of 275 nm.

The reason why the peak wavelength of ultraviolet rays is 275 nm is that the wavelength is 270 nm, which is the wavelength absorbed best by the DNA or RNA of a normal bacteria or virus, while being somewhat separated from 255 nm, which is the wavelength absorbed by the normal human DNA. This is because the wavelength is very close to. Conventional UVC lamp has a problem that the absorption of the human body than the above pathogens by irradiation of ultraviolet rays having a peak wavelength in the vicinity of 253nm, the present invention, UV light source using a UV LED that can be produced by adjusting the peak wavelength By setting the peak wavelength toward the wavelength that the DNA or RNA of the pathogen is better absorbed, the sterilization efficiency for the pathogen is further increased, and the risk to the body is minimized. In particular, since the LED has a narrow half width of the spectrum, an LED having a peak wavelength in the vicinity of 275 nm can significantly reduce the UV intensity in the vicinity of 255 nm compared to a conventional UVC lamp. Therefore, the peak wavelength of the UV LED may be set within the range of 260 nm to 280 nm, and more preferably, the peak wavelength may be set within the range of 265 nm to 275 nm to reduce the effect on the body and to increase the bactericidal power against the pathogen.

The inner casing 50 includes a rear flat portion 51 having a circular flat plate shape and a cylindrical side surface portion 53 extending forward from the edge of the rear surface 51 (above in the drawing in FIG. 2). A substrate 42 is provided on an inner surface of the back portion 51, and an ultraviolet light emitting diode 40 is mounted on the substrate 42 to irradiate ultraviolet rays toward the front. A stethoscope plate receiving portion 70 is located in front of the ultraviolet light emitting diode 40, which is surrounded by the side portion 53 of the inner casing 50.

The inner side 57 of the side portion 53 of the inner casing 50 is fixed with a protective window 71 in the form of a circular flat plate. The protective window 71 is a material through which the DUV is not absorbed and can be mostly transmitted. For example, the protective window 71 may be quartz, fused silica, or a mixture thereof. The transmittance of the DUV is preferably 80% or more, more preferably 95% or more. While the protective window 71 protects the ultraviolet light emitting diode 40 from the outside, the front surface thereof is a boundary of the stethoscope plate accommodating portion 70. That is, the space is defined by the stethoscope plate receiving portion 70 by the front surface of the protective window 71 and the inner surface 57 of the inner casing 50.

On the inner side 57 of the inner casing 50, a stethoscope plate fixture 73 is provided further forward than the position where the protective window is installed. The stethoscope plate fixing member 73 is configured to fix and support the stethoscope plate accommodated in the stethoscope plate receiving unit 70. The stethoscope plate fixture 73 is deformed or its position is changed when the stethoscope plate is inserted into the stethoscope plate receiving portion 70, and after the stethoscope plate is inserted into the stethoscope plate receiving portion, the deformation of the stethoscope plate fixture is eliminated or removed. The stethoscope will be fixed by moving in the direction of returning to the position. Detailed description thereof will be described later with reference to FIGS. 7 to 9.

The inner casing 50 is in close contact with the back of the substrate 42. The ultraviolet light emitting diode 40 has a lower efficiency of converting electrical energy into light energy than in the visible light region, which tends to be particularly lower toward the DUV region. In addition, since energy that is not converted from electrical energy to light energy is eventually converted into heat, in the case of a diode that emits ultraviolet rays in the UVC region necessary for sterilization, the amount of heat generated is considerable. Accordingly, in the present invention, the inner casing 50 is closely attached to the rear surface of the substrate so that heat generated from the ultraviolet light emitting diode can be quickly discharged to the outside. The inner casing 50 is made of a high thermal conductivity material, for example, aluminum. Since aluminum is a material that reflects ultraviolet rays well, if the inner casing is made of aluminum, the inner surface 57 of the inner casing 50 may be realized as a surface capable of reflecting ultraviolet rays well.

In particular, the present invention pays attention to the fact that the heat generation amount of the ultraviolet light emitting diode is considerable, and it is one technical feature to use such heat for heating the stethoscope plate. To this end, in the present invention, the side surface portion 53 extending in the vertical direction from the edge of the back portion 51 of the inner casing 50 is formed in a cylindrical shape, and the stethoscope plate accommodating portion 70 is disposed therein. Therefore, the heat generated when the ultraviolet light-emitting diode is turned on is transferred to the side surface portion 53 via the back portion 51 of the inner casing 50 in close contact with the back surface of the substrate, and the heat is transferred to the stethoscope plate accommodating portion 70. It is used to heat the stethoscope plate 15 accommodated in the).

In order to efficiently use the heat generated in the ultraviolet light emitting diode to heat the stethoscope plate, the present invention is another technical feature of surrounding the outer portion of the inner casing 50 with the outer casing 60. The outer casing 60 may be made of an insulating material having a much lower thermal conductivity than the inner casing 50. Referring to FIG. 2, the outer casing 60 made of a heat insulating material covers a rear surface of the rear portion 51 of the inner casing and an outer surface of the side portion 53. In other words, the outer casing may also be referred to as a concave shape whose top is open. The outer casing 60 of this type prevents heat generated from the ultraviolet light emitting diodes from escaping through the rear surface of the rear portion 51 of the inner casing and the outer surface of the side portion 53, and the rear portion 51 and the side portion 53. While passing through the inner casing (50) of the inner surface (57) and the front (55) to let out. As heat generated in the ultraviolet light emitting diode is conducted in the inner casing and escapes through the inner side and the front side, the stethoscope plate accommodated in the stethoscope plate receiving portion may be heated. As described above, according to the present invention, while sterilizing the stethoscope plate with ultraviolet rays irradiated from the ultraviolet light emitting diodes, heat generated from the ultraviolet light emitting diodes is rapidly dissipated to prevent the luminous efficiency of the ultraviolet light emitting diodes from being lowered, and at the same time, the stethoscopes are in the path of heat dissipation. It is possible to heat the stethoscope plate by heat generated from the ultraviolet light emitting diode without a separate heating means by having a plate receiving portion.

Figure 3 is a side cross-sectional view (a) and a plan view (b) showing a stethoscope sterilization apparatus according to a second embodiment of the present invention. The sterilization apparatus shown in FIG. 3 differs from that in FIG. 2 in that the outer casing 60 protrudes further forward than the front face 55 of the inner casing 50. The protruding portion 62 of the outer casing prevents the user's hand from directly contacting the front surface 55 of the inner casing 50 while exposing the front surface 55 of the inner casing 50 to the outside to improve heat dissipation efficiency. Raised.

In addition, the outer casing 60 of the present invention may further include a shield 64 covering at least a portion of the front surface 55 of the inner casing 50. The shield 64 covers at least a portion of the front surface of the inner casing 50 so that heat transferred from the back portion 51 of the inner casing 50 to the side portion 53 is greater than the front surface 55 than the front surface 55. By more exiting, it is possible to further increase the heating efficiency of the stethoscope plate accommodated in the stethoscope plate receiving portion (70). In addition, the shield 64 further functions to prevent the user's hand directly touching the front of the inner casing.

The shield 64 may have a shape extending inward from an end of the cylindrical outer casing 60 as shown in FIG. 3. The length of the shielding portion may be such that it covers a part of the inner casing front surface 55, or may cover the entire inner casing front surface. In addition, as shown in (b) of FIG. 3, it is also possible to configure such that the partially extended portion and the fully extended portion are arranged alternately inwardly along the circumference, this form of the user's hand on the front of the inner casing It is noteworthy that heat dissipation can be achieved through the front surface without direct contact.

Figure 4 is a side cross-sectional view showing a stethoscope sterilization apparatus according to a third embodiment of the present invention, Figure 5 is a view showing a state in which the stethoscope sterilization apparatus shown in Figure 4 inserted into the tube of the stethoscope.

Stethoscope sterilization apparatus of the present invention is simply considering the function of sterilizing and warming by inserting a stethoscope plate, considering the environment using the same. Referring to Figure 4, the backside of the sterilization apparatus includes a flat surface. This is to make it easy to place the back of the sterilization apparatus on a flat floor such as a desk. For example, when a doctor sees a patient in a doctor's office, he or she is placed with a stethoscope on the doctor's desk. In consideration of such a usage environment, in the present invention, the rear surface of the sterilization apparatus is formed flat and the anti-slip pad 85 is attached, thereby making it convenient to use the sterilization apparatus on a desk.

Next, a tube accommodating groove 81 for inserting the tube 14 of the stethoscope 1 in the back of the stethoscope sterilization device was provided to allow the tube to be inserted therein, and the tube 14 was inserted into the tube accommodating groove. The tube was fixed with a tube fixture so that the tube did not come out of the tube receiving groove (81). Tube fixture 82 may be a protruding jaw shown in FIG. 4. That is, when the tube 14 is forcibly inserted between the tube fixtures 82, the tube is deformed and received in the tube receiving groove 81. After the tube is received, the tube is caught by the tube fixture 82 while the tube is restored to its original shape by elasticity. Will not fall out from the receiving groove (81). Also, when the tube 14 is removed from the tube receiving groove 81, if the tube is similarly forcibly pulled out, the tube may be deformed and drawn out between the tube fixtures 82.

In the embodiment of the present invention, but the locking jaw structure that can be implemented in the simplest way, but in addition to the opening and closing by the hinge shaft, or can be applied to the tube fixture 82 of various forms, such as a snap structure of course. .

Tube receiving groove 81 and the fixture 82 is to consider the environment in which the doctor moves and uses a stethoscope. That is, as shown in FIG. 5, the stethoscope 14 is worn while the tube 14 of the stethoscope 1 is inserted into the tube receiving groove, and the stethoscope plate 15 is inserted into the sterilization apparatus 3 when the stethoscope is not used. When you want to use a stethoscope, you can use the stethoscope in such a way that by removing the stethoscope plate (15).

6 is a perspective view of the stethoscope sterilization apparatus of FIG. Although not shown, a secondary battery capable of charging and discharging may be built in the stethoscope sterilizer. Of course, the outer casing 60 is provided with a charging terminal 91 for charging such a secondary battery. Since the ultraviolet light emitting diode 40 is located inside the protective window 71, it is reliably protected from external shock. A circumference of the stethoscope plate accommodating part 70 is provided with a fixture 73 for fixing the stethoscope plate.

7 is a partial side cross-sectional view of a stethoscope sterilization apparatus showing an embodiment of a stethoscope plate fixture of the stethoscope sterilization apparatus. As shown in FIG. 7, a part of the ball 77 may protrude from the inner surface of the inner casing 50, and the ball 77 is elastically supported toward the center of the sterilization device by a spring, which is an elastic member 75. do. According to this structure, the ball is pressed by the stethoscope plate in the process of accommodating the stethoscope plate 15 in the accommodating part 70 and received into the inner casing, and then protrudes again when the stethoscope plate is fully inserted into the accommodating part. Interference with the back prevents the stethoscope board from exiting the receptacle.

8 is a plan view of a stethoscope sterilization apparatus showing another embodiment of the stethoscope plate fixture of the stethoscope sterilization apparatus, and FIG. 9 is a cross-sectional view taken along line AA ′ of FIG. 8. As illustrated, as the stethoscope plate fixture 73, an annular ring 78 made of synthetic rubber or silicone, which is an elastic member 75, may be used. The annular ring 78 may be implemented in a divided form as shown in FIG. 8 as well as in the form of a single ring as a whole. The cross-sectional shape of the annular ring 78 may be formed in a shape corresponding to the cross-sectional shape of the back of the stethoscope plate as shown in FIG. According to such a stethoscope plate fixture, when the stethoscope plate is inserted, the annular ring 78 is elastically deformed by the outer peripheral surface of the stethoscope plate to pass through the stethoscope plate, and after the stethoscope plate is completely received, the annular ring 78 is returned to its original state. It is elastically restored to form. Since the cross-sectional shape of the annular ring 78 corresponds to the cross-sectional shape of the back of the stethoscope plate, when the annular ring 78 is elastically restored as described above, the annular ring 78 interferes with the back of the stethoscope plate to fix the stethoscope plate. .

As described above, the stethoscope plate fixture may be implemented in such a way that its position is changed or its shape is changed in the process of passing the stethoscope plate, and after passing through the stethoscope plate, it is returned to its original position or restored to its original shape.

On the other hand, the present invention further includes a detection unit for detecting whether the stethoscope plate is inserted into the stethoscope plate receiving unit. This is a safety device for operating the ultraviolet light emitting diode only when the stethoscope plate is accommodated in the receiving portion, so that the user is not exposed to ultraviolet rays for sterilization.

Referring to FIG. 9, the trigger switch 74 may be used as such a safety device. The trigger switch 74 is a switch that distinguishes a state in which the switch is physically pressed and a state in which the switch is not pressed. When the trigger switch 74 is installed in the stethoscope plate accommodating part 70 as illustrated, the trigger switch 74 is triggered by the stethoscope plate. It is possible to judge whether the stethoscope board is accommodated based on whether the switch is pressed. In the present invention, a structure in which the trigger switch is installed on the inner side 57 of the inner casing is illustrated, but the installation position of the trigger switch may vary. These trigger switches are connected in series and are installed at two or more positions spaced apart from each other, so that the stethoscope plate can be determined to be inserted into the stethoscope plate accommodating unit only when all trigger switches are pressed at the same time. For example, even if a person touches a stethoscope switch protective device and accidentally presses one trigger switch, the stethoscope plate may not be judged to be inserted unless both trigger switches installed at two or more positions apart from each other are pressed.

In addition, although not shown, a photosensitive sensor capable of sensing light in the visible light region is mounted together on the substrate 42 so that the stethoscope plate is inserted into the receiving part only when the photosensitive sensor does not detect visible light. It is also possible. That is, when the stethoscope plate is accommodated in the stethoscope plate accommodating part and the external light cannot reach the substrate part, the photosensitive sensor does not detect visible light, and thus the stethoscope plate is accommodated in the accommodating part. The photosensitive sensor may be mounted on a substrate separately from the ultraviolet light emitting diode, or may be mounted on the substrate in the form of a package with the ultraviolet light emitting diode.

In addition, by measuring the distance continuously using a distance measuring sensor (IR sensor, etc.), it is also possible to determine whether the stethoscope plate is accommodated in the accommodating part by determining whether the stethoscope plate is in the state in which the stethoscope plate is accommodated. .

According to the present invention, two or more sensing units having different principles as described above may be installed, and the power may be controlled to supply power to the ultraviolet light emitting diode only when all of them detect that the stethoscope plate is accommodated in the receiving unit. For example, if only the distance measuring sensor is installed, there is a possibility of erroneous detection when an object other than a stethoscope plate enters the stethoscope plate receiver. There is a possibility that the trigger switch may be misdetected due to the user being accidentally pressed in the process of touching the sterilization device. Accordingly, the present invention can control the ultraviolet light emitting diode from the ultraviolet light emitting diode only when the plurality of sensing parts for detecting whether the stethoscope plate is mounted in the different principles are detected.

It is preferable that the light emission time of ultraviolet rays is made until the sterilization rate is 99.9% or more. According to the present invention, since the distance between the ultraviolet light emitting diode 40 and the stethoscope plate 15 is very close, sterilization can be completed within a few minutes. Therefore, in the present invention, when it is detected that the stethoscope plate 15 is accommodated in the stethoscope plate accommodating part 70, ultraviolet rays may be irradiated for a preset time.

On the other hand, in the present invention, in consideration of the fact that the stethoscope plate is excessively heated and may cause the patient to feel hot or burned, if the stethoscope plate is heated above the set temperature, a temperature sensing means for shutting off the power supplied to the ultraviolet light emitting diode is provided. Can be. As such a temperature sensing means, a method in which a deformation is made when the temperature rises above a predetermined temperature, such as bimetal, may be used to disconnect the electrical contact. On the contrary, it is also possible to detect when the stethoscope board is too cold and to control the power supply to the ultraviolet light emitting diode.

10 to 21 relates to a sterilizing apparatus of a stethoscope including a heating member. 10 to 21, the description of the same configuration as the stethoscope sterilizer according to the first to third embodiments will be omitted.

The heat generating member 110 is a component that heats the stethoscope plate 15 when the stethoscope 1 is mounted to the sterilization apparatus 3. By the heating member 110 to maintain the stethoscope plate 15 to a warm temperature, the patient may not feel discomfort due to the cold stethoscope.

In the sterilization apparatus 3 according to the fourth embodiment, the heat generating member 110 is disposed on the front surface of the rear portion 51 of the inner casing 50. Here, the front surface of the rear part 51 is a surface facing the stethoscope plate accommodating part 70, and the opposite surface is a rear surface. The heat generating member 110 is a heat dissipating component. In the fourth embodiment, the heat generating member 110 emits infrared light to generate heat. For example, the heating member 110 that emits infrared light may be an infrared light emitting diode or an infrared lamp.

The heat generating member 110 emits infrared light to the protective window 71. Therefore, when the stethoscope plate 15 is located in the stethoscope plate accommodating part 70, the stethoscope plate 15 is heated by the infrared light of the heat generating member 110.

Referring to FIG. 10, the heating member 110 is mounted on the substrate 42 on which the ultraviolet light emitting diode 40 is mounted. In this case, the ultraviolet light emitting diode 40 and the heat generating member 110 are supplied with power by one substrate 42. However, the present invention is not limited to such a structure.

The heat generating member 110 may be directly mounted on the rear surface 51 of the inner casing 50 or may be mounted on a separate component from the substrate 42 of FIG. 10. As such, when the ultraviolet light emitting diode 40 and the heat generating member 110 are disposed in different components, the heat of the heat generating member 110 may reduce the influence on the ultraviolet light emitting diode 40. In addition, a control component that controls the heating operation of the heat generating member 110 may be located inside or outside the inner casing 50, and may be electrically connected to the heat generating member 110.

The heat generating member 110 may be operated in conjunction with the ultraviolet light emitting diode 40. That is, the heating member 110 may start the heating or stop the heating according to an on operation of irradiating the ultraviolet light of the ultraviolet light emitting diode 40 or an off operation of stopping the ultraviolet irradiation.

In addition, the heating member 110 may operate by the ultraviolet light emitting diode 40 and a timer (not shown). For example, the heating member 110 starts to generate heat when the ultraviolet light emitting diode 40 starts ultraviolet irradiation. Thereafter, the heating member 110 generates heat for a time set by the timer, and stops the heating operation after the set time elapses.

In addition, the heating member 110 may start the heating or stop the heating by receiving a signal by the trigger switch described in the previous embodiment. The trigger switch described in the previous embodiment is formed as a separate component from the stethoscope plate fixture 73. However, the stethoscope plate fixture 73 may also serve as a trigger switch at the same time. When the stethoscope 1 is mounted to the sterilization device 3, at least a part of the stethoscope plate fixture 73 is inserted into the inner casing 50 by the stethoscope plate 15, or it has been inserted back into its original position. You can return. In this case, a part of the stethoscope plate fixture 73 inserted into the inner casing 50 may transmit a signal to a component (not shown) disposed in the inner casing 50 by contacting or pressing. In this case, the component receiving the signal may transmit a signal such that the heating member 110 performs the heating operation.

On the contrary, when the stethoscope 1 is detached from the sterilizing device 3, at least a part of the stethoscope plate fixture 73 is inserted into it and returned to its original position. At this time, the stethoscope plate fixture 73 transmits a signal to the component disposed inside the inner casing 50, and eventually the heating member 110 stops the heating operation.

In addition, the heating member 110 may operate by receiving a signal indicating that the stethoscope 1 is mounted or detached from the sterilizing device 3 from the sensing unit such as the photosensitive sensor and the distance measuring sensor described in the previous embodiment.

In addition, the heat generating member 110 is a trigger switch, a stethoscope plate fixture 73 that also serves as a trigger switch, a signal indicating that the stethoscope 1 is mounted or detached from the sterilization device 3, all from two or more components of one or more detection units When received, fever may begin or stop fever.

That is, the heating member 110 may operate by receiving a separate signal from the trigger switch, the stethoscope plate fixture 73, the sensing unit, etc., instead of the signal caused by the operation of the ultraviolet light emitting diode 40.

In addition, the sterilization apparatus 3 may further include a temperature sensing means 120. The temperature sensing unit 120 controls the heating member 110 to maintain the temperature of the stethoscope plate 15 in a predetermined range. When the temperature exceeds the maximum value of the set range, the temperature sensing means 120 may stop the heat generation of the heat generating member 110. In addition, if the temperature is less than the minimum value of the set range, the temperature sensing means 120 may cause the heating member 110 to start to generate heat. The temperature detected by the temperature sensing means 120 may be the temperature of the stethoscope plate 15 or the temperature of the surrounding space of the heat generating member 110.

By the temperature sensing means 120, the stethoscope plate 15 can be prevented from being heated too hot or kept cold to be harmful or unpleasant to the patient.

The above-described heating start and heat generation stop method of the heating member 110 may be equally applied to the heating member 110 in the following embodiment.

11 is a cross-sectional view of the sterilizing apparatus of the stethoscope according to the fifth embodiment of the present invention. 12 and 13 are exemplary views showing an embodiment of a heating member, respectively.

In the sterilization apparatus 3 according to the fifth embodiment, the heating member 130 is disposed on the front surface of the protective window 71. Here, the front surface of the protective window 71 is a surface located in the stethoscope plate receiving portion 70. The heat generating member 130 is formed of a material that generates heat when the power is supplied. For example, the heating member 130 may be formed of a hot wire or a thermal fiber. Although not shown, a control component for supplying power to the heat generating member 130 and controlling the operation of the heat generating member 130 may be formed inside or outside the inner casing 50.

When the stethoscope 1 is mounted on the sterilizing device 3, the lower surface of the stethoscope plate 15 is located in close contact with or in contact with the heat generating member 130. Here, the lower surface of the stethoscope plate 15 is a surface sterilized by ultraviolet rays. Therefore, heat of the heat generating member 130 may be directly transmitted to the stethoscope plate 15.

The heating member 130 may be formed on the edge of the protective window 71 as shown in FIG. Alternatively, the heating member 130 may be formed in a lattice structure on the protective window 71 as shown in FIG. 13. At this time, in the portion where the heat generating member 130 is not located in the protective window 71, ultraviolet rays of the ultraviolet light emitting diodes 40 are passed through and irradiated to the stethoscope plate 15.

12 and 13 is a structure of the heating member 130 as an embodiment, the structure of the heating member 130 is not limited thereto. The heating member 130 may be formed in a variety of structures if a sufficient amount of ultraviolet light for sterilization of the stethoscope plate 15 can be irradiated to the stethoscope plate 15 through the protective window 71.

According to an embodiment of the present invention, the heat generating member 130 is disposed on the protective window 71, the ultraviolet light emitting diode 40 is disposed on the back portion 51 of the inner casing 50, different components Is placed. In addition, the heat generating member 130 and the ultraviolet light emitting diode 40 are positioned at different heights. Thus, the heat generating member 130 has a long heat conduction path to the ultraviolet light emitting diode 40. The heat generated from the heat generating member 130 by the heat conduction path may reduce the influence of the ultraviolet light emitting diodes 40, thereby preventing the ultraviolet light emitting diodes 40 from being damaged.

According to the sixth embodiment, the heat generating member 140 is formed on the inner wall of the side portion 53 that forms the stethoscope plate receiving portion 70 in the inner casing 50. Here, the inner wall of the side portion 53 corresponds to the inner side 57 of the inner casing 50. For example, the heating member 140 may be formed of a hot wire or a thermal fiber. The heat generating member 140 may be formed in various structures, and may be continuously or discontinuously formed along the inner surface 57 of the inner casing 50.

When the stethoscope 1 is mounted on the sterilization apparatus 3, the side surface of the stethoscope plate 15 is in close contact with or is in contact with the heating member 140. Therefore, the heat of the heat generating member 140 is transmitted through the side of the stethoscope plate 15, the stethoscope plate 150 is heated.

According to the seventh embodiment, the inner casing 50 includes a back portion 51, a side portion 53, and an insulation portion 150. In the present embodiment, the heating member 140 is formed on the inner wall of the side portion 53.

The insulation part 150 is formed between the side part 53 and the back part 51. The insulating part 150 may be formed of a material having a different thermal conductivity from at least one of the side part 53 and the rear part 51. For example, the insulating part 150 is formed of a material having a lower thermal conductivity than the side part 53 and the rear part 51. The rear part 51 and the side part 53 are thermally separated by the insulating part 150 formed of a material having low thermal conductivity. Therefore, it is possible to prevent the heat of the heat generating member 140 from being conducted to the back portion 51 through the side portion 53. In addition, since the rear part 51 and the side part 53 are thermally separated, the rear part 51 only performs heat radiation with respect to the ultraviolet light emitting diode 40. Therefore, the heat radiation efficiency with respect to the ultraviolet light emitting diode 40 is improved.

According to an embodiment of the present invention, the back portion 51 and the side portion 53 constituting the inner casing 50 may be formed of the same material, it may be formed of different materials. When the back portion 51 and the side portion 53 are formed of different materials, they may be formed of materials having different thermal conductivity. For example, the side portion 53 may be formed of a material having low thermal conductivity to insulate the stethoscope 1, and the rear part 51 may be formed of a material having high thermal conductivity to dissipate the light emitting diodes 40. .

According to the eighth embodiment, the inner casing 50 consists of a back portion 51 and a side portion 53. In addition, the side portion 53 includes a first side portion 58, a second side portion 59, and an insulation portion 150.

The first side portion 58 is in contact with the rear portion 51, and the second side portion 59 is formed in front of the first side portion 58. In the present embodiment, the heat generating member 140 is formed on the inner wall of the second side portion 59.

The insulating portion 150 is formed between the first side portion 58 and the second side portion 59. The insulating part 150 may be formed of a material having a different thermal conductivity from at least one of the first side part 58 and the second side part 59. For example, the insulation portion 150 is formed of a material having a lower thermal conductivity than the first side portion 58 and the second side portion 59. The first side portion 58 and the second side portion 59 are thermally separated by the insulating portion 150. That is, the insulating part 150 prevents the heat of the heat generating member 140 formed in the second side part 59 from being conducted to the first side part 58. Therefore, it is possible to prevent the heat of the heat generating member 140 from being conducted to the ultraviolet light emitting diode 40 through the inner casing 50.

In addition, since the first side portion 58 and the second side portion 59 are thermally separated from each other, the first side portion 58 and the rear portion 51 only perform heat radiation on the ultraviolet light emitting diode 40. Therefore, the heat radiation efficiency with respect to the ultraviolet light emitting diode 40 is improved.

In another embodiment, when the inner casing 50 is formed on the front surface of the protective window 71, the insulating part 150 may be formed at a lower position than the protective window 71 or the inner casing 50. Even in this case, the heat of the inner casing 50 formed in the protective window 71 through the insulating portion 150 can be prevented from being conducted to the first side surface portion 58.

According to the exemplary embodiment of the present disclosure, the back part 51, the first side part 58, and the second side part 59 may be formed of the same material, and at least one may be formed of a different material. For example, the second side portion 59 is formed of a material having low thermal conductivity for keeping the stethoscope 1 warm, and the rear portion 51 and the first side portion 58 have high thermal conductivity for heat radiation of the light emitting diode. It may be formed of a material. In addition, when the back portion 51 is not integral with the first side portion 58, it may be formed of different materials.

According to the ninth embodiment, the substrate 42 and the ultraviolet light emitting diode 40 are located inside the back 51 of the inner casing 50.

A cavity 54 is formed in the rear portion 51 of the inner casing 50. An ultraviolet light emitting diode 40 is disposed in the cavity 54.

17 illustrates a structure in which the substrate 42 is disposed below the cavity 54. However, the present invention is not limited thereto, and both the substrate 42 and the ultraviolet light emitting diode 40 may be disposed in the cavity 54.

In addition, the protective window 71 is disposed in the cavity 54. The protective window 71 is located in front of the ultraviolet light emitting diode 40, and one surface of the protective window 71 is positioned in line with one surface of the rear part 51. Here, one surface of the protective window 71 and one surface of the rear part 51 are surfaces exposed to the stethoscope plate accommodating part 70. However, the position where the protective window 71 is disposed is not limited thereto. The protective window 71 may be disposed at any position between the ultraviolet light emitting diode 40 and the stopper 160.

The heat generating member 140, the stopper 160, and the trigger switch 74 are formed at the side portion 53 of the inner casing 50.

The stopper 160 is formed to protrude from the side portion 53 of the inner casing 50, and is formed to be located in front of the ultraviolet light emitting diode 40. When the stethoscope 1 is mounted on the sterilizing apparatus 3, the lower surface of the stethoscope plate 15 comes into contact with the stopper 160.

The stopper 160 is for separating the stethoscope plate 15 from the ultraviolet light emitting diode 40 and the rear part 51 when the stethoscope 1 is mounted on the sterilization apparatus 3. When the stethoscope plate 15 is located too close to the ultraviolet light emitting diode 40, ultraviolet rays are not irradiated on the entire lower surface of the stethoscope plate 15. Therefore, in order to irradiate ultraviolet rays to the entire lower surface of the stethoscope plate 15, a space between the stethoscope plate 15 and the ultraviolet light emitting diode 40 is required. In addition, when the stethoscope plate 15 comes in contact with the rear part 51, ultraviolet rays are not irradiated to a portion of the bottom surface of the stethoscope plate 15 that comes into contact with the back part 51. Therefore, the stethoscope plate 15 should also be spaced apart from the ultraviolet back part 51.

The trigger switch 74 is for detecting that the stethoscope 1 is mounted to the sterilization device 3. Instead of the trigger switch 74, it is possible to apply any of the sensing units described in the previous embodiment.

In addition, in the present exemplary embodiment, the heating member 140 is formed on the side portion 53 by way of example. However, the heat generating member 140 may be formed on one surface of the rear portion 51 or both the side portion 53 and the rear portion 51.

In the present embodiment, it is also possible to omit the protective window 71 at the choice of those skilled in the art.

According to the tenth embodiment, the substrate 42 is located inside the back 51 of the inner casing 50. In addition, a part of the ultraviolet light emitting diode 40 is located inside the rear part 51, and the other part is located outside the rear part 51. A stopper 160 is formed on the side portion 53 of the inner casing 50. The stopper 160 is positioned in front of the ultraviolet light emitting diode 40 to space the stethoscope plate 15 from the ultraviolet light emitting diode 40.

As such, when the stethoscope 1 is mounted to the sterilization apparatus 3 by the stopper 160, ultraviolet rays may be irradiated on the entire lower surface of the stethoscope plate 15. In addition, although a part of the ultraviolet light emitting diode 40 is located outside the rear part 51, the protective window 71 is omitted since the ultraviolet light emitting diode 40 does not contact the stethoscope plate 15 by the stopper 160. can do.

In addition, the substrate 42 and the ultraviolet light emitting diode 40 may also be disposed on the front surface of the rear portion 51 may be applied to the present embodiment.

19 is a cross-sectional view of a sterilizing apparatus of a stethoscope according to an eleventh embodiment of the present invention. 20 is a plan view of a sterilizing apparatus of a stethoscope according to an eleventh embodiment of the present invention.

According to the FIG. 11 embodiment, the inner casing 50 is composed of a back portion 51, a first side portion 58 and a second side portion 59. The first side portion 58 is in contact with the rear portion 51, and the second side portion 59 is formed in front of the second side portion 59.

The protective window 71 is formed of a material that transmits ultraviolet rays and has low thermal conductivity. The heating member 130 is disposed on the front surface of the protective window 71.

A portion of the protective window 71 and the heat generating member 130 is disposed between the first side portion 58 and the second side portion 59. That is, this embodiment has a structure in which the first side portion 58, the protective window 71, the heating member 130 and the second side portion 59 are stacked.

Since the protective window 71 is formed of a material having low thermal conductivity, the first side portion 58 and the second side portion 59 are thermally separated. Alternatively, the heat generating member 130 and the first side portion 58 are thermally separated. That is, it is possible to prevent the heat of the heat generating member 130 from being transferred to the first side surface portion 58 by the protective window 71 to affect the ultraviolet light emitting diode 40.

In the present embodiment, the heat generating member 130 has been described as an example disposed between the first side portion 58 and the second side portion (59). However, only the protective window 71 is disposed between the first side surface portion 58 and the second side surface portion 59, and the heat generating member 130 is disposed in front of the protective window 71 in the stethoscope plate accommodating portion 70. It is also possible. Alternatively, the heating member 130 may be formed on the inner wall of the second side portion 59.

The outer casing 60 is formed to surround a portion of the outer side 56 and the front side 55 of the inner casing 50. That is, the outer casing 60 is formed to surround a part of the front surface of the second side portion 59 and the outer surfaces of the first side portion 58 and the second side portion 59. The first side part 58, the second side part 59, the protective window 71, and the heat generating member 130 are fixed to each other without a separate adhesive material by the outer casing 60 formed as described above. In addition, the heat of the heat generating member 130 is prevented from being released to the outside by the outer casing 60, so that the heating efficiency of the stethoscope plate 15 is improved. Here, the portion surrounding the front surface 55 of the inner casing 50 in the outer casing 60 corresponds to the shield (64 in FIG. 3). As shown in FIG. 3, a plurality of shields 64 may be formed to be spaced apart from each other. In addition, although not shown, the shield 64 may be continuously formed along the front surface 55 of the inner casing 50. For a detailed description and effects of the shield 64, refer to the description of FIG.

In addition, the outer casing 60 is formed to expose the back surface of the back portion 51 of the inner casing 50 to the outside. Therefore, since the rear part 51 can directly radiate heat of the ultraviolet light emitting diode 40 to the outside, the heat dissipation effect of the sterilization apparatus 3 can be improved.

Referring to FIG. 21, the outer casing 60 is formed to surround a portion of the outer surface 56 and a portion of the front surface 55 of the inner casing 50. That is, the outer casing 60 may include a portion of the front surface of the second side portion 59, an outer surface of the second side portion 59, a protective window 71, a portion of the outer surface of the heat generating member 130, and the first side portion 58. It is formed to surround.

By the outer casing 60, the first side part 58, the second side part 59, the protective window 71, and the heat generating member 130 are fixed so as not to separate from each other without a separate adhesive material. In addition, since the heat of the heat generating member 130 is prevented from being released to the outside by the outer casing 60, the heating efficiency of the stethoscope plate 15 is improved.

In addition, the outer casing 60 is formed to expose a portion of the outer side surface of the first side surface portion 58 and the rear surface of the rear surface portion 51 to the outside. Therefore, the first side portion 58 and the back portion 51 may directly radiate heat of the ultraviolet light emitting diode 40 to the outside through the portion exposed to the outside. Therefore, the heat dissipation effect of the sterilization apparatus 3 can be improved.

Although not shown in FIGS. 1 to 21, a reflection member for reflecting ultraviolet rays may be further formed on the inner surface of the inner casing or the inner surface of the cavity. The reflection member may increase the sterilization efficiency of the sterilization apparatus by preventing the ultraviolet rays emitted from the ultraviolet light emitting diodes from being absorbed and lost by the inner casing.

Although the present invention has been described with reference to the drawings exemplified as above, the present invention is not limited to the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that modifications can be made. In addition, even if the above described embodiments of the present invention while not explicitly described by describing the effect of the configuration of the present invention, it is obvious that the effect predictable by the configuration is also to be recognized.
