Description

Sterilizing Apparatus for Stethoscope

The present invention relates to a sterilizing apparatus for a stethoscope, and more particularly, to a sterilizing apparatus for preventing a stethoscope from being cold during storage of a stethoscope for a while, thereby preventing a patient from feeling uncomfortable due to a cold stethoscope, To a sterilizing device for a stethoscope capable of sterilizing.

The stethoscope was first used in 1816 as the invention of the French physician Laennec, R. A stethoscope is a device that amplifies and hears the sounds of a person's heart, lungs, and bowels. The doctor puts a stethoscope on the body part where he or she wants to hear the sound while listening to the amplified sound.

However, since the portion of the stethoscope that touches the human body is not a single-use, it is constantly in contact with the skin of many patients. This form of use may cause transmission of bacterial or viral skin diseases.

Also, the area of the stethoscope should be in close contact with the skin. On a cold day, the area of the stethoscope is too cold, and the patient who comes in contact with the stethoscope may feel frightened or uncomfortable with the cold stethoscope.

In order to solve such a problem, a technique has been disclosed in which a stethoscope is sterilized with an ultraviolet LED (light emitting diode) and a stethoscope is heated using a heat generating means to maintain an uncooled state.

However, the conventional stethoscope sterilization and heating method has a structure for sterilizing the stethoscope and a structure for heating the stethoscope separately, so that the number of internal structures is too large compared to the size of the apparatus, which is complicated and requires a lot of power consumption.

The technology also lacks an indication of an ultraviolet light source that can be most effective against bacterial or viral contamination that may occur in contact with any skin. In addition, the fact that the safety of ultraviolet rays with a high energy level is so low as to have sterilizing power is also insufficient.

Next, there is also a lack of understanding of the environment in which a stethoscope is always carried by a doctor.

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

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

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

Typically, the stethoscope 1 is provided with a stenting plate 15 at one end of the Y-shaped tube 14 to contact the patient's body and a branch tube 12 at the other end of the tube. The branch pipe 12 is elastically supported in the direction of being tightened close to each other by the clip 13 provided at one end of the branch pipe 12 and the other end of the branch pipe 12 is connected to the ear plug 11, Respectively.

The stethoscope sterilizing device 3 according to the present invention is a device for sterilizing and protecting the stethoscope 1 of the stethoscope 1 described above. The stethoscope sterilizing device 3 is formed in a substantially cylindrical shape so as to surround a circular stent plate. The sterilizing device (3) has a stethoscope receiving portion (70) surrounded by an inner casing (50). The inner casing has a concave shape with its top surface opened. The entrance side of the concave space serves as a stethoscope receiving portion 70, and a substrate (not shown) having an ultraviolet light emitting diode (UV LED) 42 are installed. In one embodiment, the ultraviolet light emitted from the ultraviolet light emitting diode is a deep ultraviolet light (DUV) having a peak wavelength of 275 nm.

The reason for setting the peak wavelength of ultraviolet light to 275 nm is that the wavelength is somewhat distant from 255 nm which is the wavelength most commonly absorbed by the human body DNA and is 270 nm which is the wavelength most absorbed by ordinary bacterium or virus DNA or RNA Is very close to the wavelength. In the conventional UVC lamp, there is a problem that ultraviolet rays having a peak wavelength near 253 nm are irradiated to absorb more easily from the human body than the above-mentioned pathogens. In the present invention, by using a UV LED which can be manufactured by adjusting the peak wavelength, And by setting the peak wavelength to a wavelength that is better absorbed by DNA or RNA of the pathogen, it increases the bactericidal efficiency against pathogens, while minimizing the risk to the body. In particular, since the LED has a narrow spectrum half width, if an LED having a peak wavelength at 275 nm is constituted, ultraviolet intensity at around 255 nm can be drastically reduced as compared with a conventional UVC lamp. Therefore, the peak wavelength of the UV LED can be set within the range of 260 nm to 280 nm, and more preferably, the peak wavelength can be set within the range of 265 nm to 275 nm so that the effect on the body is reduced while the sterilizing power against pathogenic bacteria is high.

The inner casing 50 includes a circular-plate-shaped rear portion 51 and a cylindrical-shaped lateral portion 53 extending forward (upward in FIG. 2) at the edge of the rear portion 51. A substrate 42 is provided on the inner surface of the rear portion 51 and an ultraviolet light emitting diode 40 is mounted on the substrate 42 to irradiate ultraviolet rays forward. A stethoscope plate receiving portion 70 is located in front of the ultraviolet light emitting diode 40 and is surrounded by a side portion 53 of the inner casing 50.

The inner side surface 57 of the side surface portion 53 of the inner casing 50 is fixed to the protective window 71 in the form of a circular plate. The protection window 71 may be a material that can be mostly permeated without absorbing the DUV, for example, quarts, fused silica, or a mixed material thereof. The transmittance of the DUV is preferably 80% or more, more preferably 95% or more. The protection window 71 protects the ultraviolet light emitting diode 40 from the outside, and its front surface is the boundary of the stent plate accommodating portion 70. That is, the space of the stent plate receiving portion 70 is defined by the front surface of the protective window 71 and the inner surface 57 of the inner casing 50.

A stethoscope plate fixture 73 is further provided in front of the inner side surface 57 of the inner casing 50 than the position where the protective window is provided. The stethoscope plate fixture 73 is configured to fix and support the stent plate contained in the stethoscope plate receiving portion 70. The stent plate fixing member 73 is deformed or changed in position when the stent plate is inserted into the stent plate holding portion 70 and after the stent plate is inserted into the stent plate holding portion, And the stent plate is fixed. A detailed description thereof will be described below with reference to FIGS. 7 to 9.

The inner casing 50 is in close contact with the back surface of the substrate 42. The ultraviolet light emitting diode 40 has a lower efficiency of converting electric energy into light energy than in the case of the visible light region, and this tends to become lower as it goes to the DUV region in particular. In addition, energy that is not converted from electric energy to light energy is ultimately converted into heat. Therefore, in the case of a diode that emits ultraviolet rays in the UVC region necessary for sterilization, the amount of heat generated is significant. Accordingly, in the present invention, the inner casing 50 is closely attached to the back surface of the substrate so that heat generated from the ultraviolet light emitting diode can be rapidly discharged to the outside. The inner casing 50 is made of a material having high thermal conductivity, and may be aluminum, for example. Aluminum is a material which reflects ultraviolet rays well. Therefore, if the inner casing is made of aluminum, the inner surface 57 of the inner casing 50 can be realized as a surface that can reflect ultraviolet rays well.

Particularly, the present invention focuses on the fact that the calorific value of the ultraviolet light emitting diode is significant, and uses this heat for heating the stent panel. To this end, the side part 53 extending in the vertical direction at the edge of the back part 51 of the inner casing 50 is formed into a cylindrical shape, and the stethoscope receiving part 70 is disposed inside the side part. The heat generated when the ultraviolet light emitting diode is lit is conducted and transmitted to the side surface portion 53 through the back surface portion 51 of the inner casing 50 closely attached to the back surface of the substrate and the heat is transmitted to the stent plate receiving portion 70 ) Of the stent plate (15).

Another technical feature of the present invention is that the outer casing 60 surrounds the outer portion of the inner casing 50 in order to efficiently use heat generated from the ultraviolet light emitting diode in heating the stent panel. The outer casing 60 can be made of an insulating material having thermal conductivity much lower than that of the inner casing 50. Referring to FIG. 2, the outer casing 60, which is a heat insulating material, covers the back surface of the back surface portion 51 of the inner casing and the outer surface of the side surface portion 53. That is, the outer casing may also be a concave shape whose upper surface is open. The outer casing 60 of this type prevents the heat generated in the UV light emitting diode from escaping through the back surface of the back surface portion 51 of the inner casing and the outer surface of the side surface portion 53 and prevents the back surface portion 51 and the side surface portions 53 So as to escape through the inner surface 57 and the front surface 55 of the inner casing 50. Heat generated in the ultraviolet light emitting diode is conducted through the inner casing and escapes through the inner surface and the front surface, so that the stent sheet accommodated in the stent plate receiving portion can be heated. As described above, according to the present invention, even when the stent plate is sterilized by ultraviolet rays emitted from the ultraviolet light emitting diode, heat generated in the ultraviolet light emitting diode is dissipated rapidly to prevent the luminous efficiency of the ultraviolet light emitting diode from being lowered, It is possible to heat the stent plate by the heat generated from the ultraviolet light emitting diode without a separate heating means by placing the plate accommodating portion.

3 is a side sectional view (a) and a top view (b) of a stethoscope sterilizing apparatus according to a second embodiment of the present invention. The sterilizing apparatus shown in FIG. 3 differs from the sterilizing apparatus shown in FIG. 2 in that the outer casing 60 is formed further forward than the front surface 55 of the inner casing 50. The protrusion 62 of the outer casing prevents the user's hands 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, .

The outer casing 60 of the present invention may further include a shielding portion 64 covering at least a part of the front surface 55 of the inner casing 50. The shielding portion 64 covers at least a part of the front surface of the inner casing 50 so that the heat transmitted from the back surface portion 51 of the inner casing 50 to the side surface portion 53 passes through the inner surface 57 It is possible to further increase the heating efficiency of the stent plate accommodated in the stent plate accommodating portion 70. [ The shielding portion 64 further functions to prevent the user's hand from directly touching the front surface of the inner casing.

The shape of the shield 64 may be inwardly extended from the end of the cylindrical outer casing 60 as shown in FIG. The length at which the shielding portion extends may be a length that covers a part of the inner casing front surface 55 or may cover the entire surface of the inner casing. In addition, as shown in Fig. 3 (b), it is also possible to arrange such that portions extending only partially inwardly and portions extending all along the periphery are alternately arranged, It is noteworthy that it is possible to make heat dissipation through the front surface while avoiding direct contact.

FIG. 4 is a side sectional view showing a stethoscope sterilizing apparatus according to a third embodiment of the present invention, and FIG. 5 is a view showing a state where the stethoscope sterilizing apparatus shown in FIG. 4 is inserted into a tube of a stethoscope.

The stethoscope sterilization apparatus of the present invention not only functions to sanitize and insulate a stethoscope by simply inserting a stethoscope, but also considers the environment in which it is used. Referring to FIG. 4, the back surface of the sterilizing apparatus includes a flat surface. This is to make it easy to place the back surface of the sterilizing device on a flat surface such as a desk. For example, when a doctor treats a patient in an office, a doctor may put the stethoscope down on the doctor's desk, and a stethoscope can be carried only when necessary. In consideration of such a use environment, in the present invention, since the back surface of the sterilizing device is made flat and the non-slip pad 85 is attached, the sterilizing device is placed on a desk and used conveniently.

Next, a tube receiving groove 81 capable of fitting the tube 14 of the stethoscope 1 is provided on the back surface of the stethoscope sterilizing device so that the tube can be inserted. After the tube 14 is inserted into the tube receiving groove The tube was fixed by the tube fixing hole so that the tube was not detached from the tube receiving groove 81. The tube fixture 82 may be a protruding lip shown in Fig. That is, when the tube 14 is forcedly inserted between the tube fixing holes 82, the tube is deformed and accommodated in the tube receiving groove 81. After being accommodated, the tube is restored to its original shape by elasticity, So that it does not come out of the receiving groove 81. Similarly, when the tube 14 is pulled out from the tube receiving groove 81, if the tube is forcibly pulled out, the tube is deformed and can escape through the tube fixing holes 82.

Although the embodiment of the present invention provides a hanging jaw structure that can be implemented most simply, it is needless to say that various types of tube fastening holes 82 such as a shape that is opened / closed by a hinge shaft or a snap structure can be applied .

The tube receiving groove 81 and the fixture 82 are designed to allow the physician to move and take the environment in which the stethoscope is used. 5, a stethoscope is worn while the tube 14 of the stethoscope 1 is inserted into the tube receiving groove. When the stethoscope is not used, the stethoscope 15 is inserted into the sterilizing device 3 , A stethoscope can be used in such a manner that the stethoscope 15 is removed when the stethoscope is used.

Fig. 6 is a perspective view of the stethoscope sterilizing apparatus of Fig. 2; Although not shown, a secondary battery capable of charging and discharging can be built in the inside of the stethoscope sterilizing device. Of course, the external casing 60 is provided with a charging terminal 91 for charging the secondary battery. Since the ultraviolet light emitting diode 40 is located inside the protection window 71, it is protected from external impact. A fixture 73 for fixing the stent plate is provided around the stent plate accommodating portion 70.

7 is a partial side cross-sectional view of a stethoscope sterilizing device showing one embodiment of a stethoscope holder of a stethoscope sterilizer. A part of the ball 77 may protrude from the inner surface of the inner casing 50 and the ball 77 may be urged toward the center of the sterilizing device by a spring as the elastic member 75, do. According to this structure, when the stent plate 15 is received in the receiving portion 70, the ball is pressed by the stent plate and received inside the inner casing. When the stent plate 15 is fully inserted into the receiving portion, Interference with the back surface prevents the stent plate from coming out of the receiving portion.

FIG. 8 is a plan view of a stethoscope sterilizing apparatus showing another embodiment of a stethoscope holder of a stethoscope sterilizing apparatus, and FIG. 9 is a sectional view taken along line A-A 'of FIG. As shown in the figure, an annular ring 78 made of synthetic rubber, silicone, or the like, which is an elastic member 75, can be used as the stethoscope plate fixture 73. The annular ring 78 can be implemented in a divided form as shown in FIG. 8, as well as a single ring as a whole. The cross-sectional shape of the annular ring 78 may be a shape corresponding to the cross-sectional shape of the back surface of the stent plate as shown in Fig. According to such a stethoscope plate fixture, when the stethoscope is inserted, the annular ring 78 is elastically deformed by the outer circumferential surface of the stethoscope plate to pass the stethoscope plate. After the stethoscope plate is completely received, . Since the sectional shape of the annular ring 78 corresponds to the sectional shape of the back surface of the stent plate, when the annular ring 78 is resiliently restored as described above, the annular ring 78 interferes with the back surface of the stent plate to fix the stent plate .

In this way, the stethoscope plate fixture can be realized in such a manner that its position is changed or its shape is deformed in the process of passing the stethoscope plate, and after the stethoscope plate is returned to its original position or restored to its original shape.

The present invention further includes a sensing unit for sensing whether or not a stethoscope is inserted into the stethoscope receiving unit. This is a safety device for preventing the user from being exposed to ultraviolet rays for sterilization by operating the ultraviolet light emitting diode only when the stent plate is accommodated in the accommodating portion.

Referring to Fig. 9, a trigger switch 74 can be used as this safety device. The trigger switch 74 is a switch for physically separating the state where the switch is pressed and the state where the switch is not pressed. When the trigger switch 74 is provided in the stethoscope receiving part 70 as shown in the figure, It is possible to judge whether or not the stent plate is accepted based on whether the switch is pressed. In the present invention, the structure in which the trigger switch is provided on the inner side surface 57 of the inner casing is illustrated, but the installation position of the trigger switch may be various. These trigger switches are connected in series and are installed at least at two or more positions apart from each other, so that it can be determined that the stent plate is inserted in the stent plate accommodating portion only when all the trigger switches are simultaneously pressed. For example, even if a person touches the stethoscope protective sterilizer and accidentally presses one trigger switch, he or she may not judge that the stethoscope is inserted unless the trigger switches installed at two or more positions apart from each other are depressed.

Also, although not shown, a photosensitive sensor capable of sensing light in the visible light region may be mounted on the substrate 42 to determine that the stethoscope is inserted into the containing portion only when the photosensitive sensor does not detect visible light It is possible. That is, since the stent plate is accommodated in the stent plate receiving part, when the external light can not reach the substrate part, the photosensor can not detect the visible light, so that the stent sheet is received in the receiving part. The photosensitivity sensor may be mounted on the 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, it is also possible to continuously measure the distance using a distance measuring sensor (IR sensor or the like) to determine whether or not the stent plate is accommodated in the accommodating portion by determining whether or not the stent plate is accommodated in the stethoscope accommodating portion .

In the present invention, two or more sensing units having different principles as described above are installed, and power can be controlled so that power is supplied to the ultraviolet light emitting diode only when they sense that the stent plate is accommodated in the accommodating portion. For example, if only a distance measuring sensor is installed, there is a possibility of misdetection when an object other than a stethoscope is received in the stethoscope holding part, and when there is a sterilizing device in a dark pocket or bag, And the trigger switch may be erroneously detected due to accidental depression, for example, when the user touches the sterilizing device. Therefore, according to the present invention, ultraviolet rays emitted from the ultraviolet light emitting diode can be controlled to emit ultraviolet rays only when a plurality of sensing units sensing the presence or absence of the receptacle of the stent plate are accommodated.

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

In the present invention, in consideration of the fact that the stent plate is excessively heated and the patient may feel hot or may be burned, in order to shut off the power supplied to the ultraviolet light emitting diodes . Such a temperature sensing means may be a bimetal, such as a bimetal, in which when the temperature rises above a predetermined temperature, deformation occurs and electrical contacts are cut off. On the contrary, it is also possible to detect that the stethoscope is excessively cold and to control the power supply to the ultraviolet light emitting diode.

10 to 21 relate to a sterilizing apparatus for a stethoscope including a heating member. 10 to 21, a description of a sterilizing apparatus for a stethoscope will be omitted. The sterilizing apparatus of the stethoscope according to the first to third embodiments will not be described.

The heating member 110 is a component for heating the stent plate 15 when the stethoscope 1 is mounted on the sterilizing device 3. [ The heating member 110 can maintain the temperature of the stethoscope 15 at a warm temperature so that the patient does not feel uncomfortable due to the cold stethoscope.

10 is an exemplary view showing a sterilizing apparatus for a stethoscope according to a fourth embodiment of the present invention.

In the sterilizing apparatus 3 according to the fourth embodiment, the heating member 110 is disposed on the front surface of the rear portion 51 of the inner casing 50. Here, the front surface of the back surface portion 51 faces the stent plate receiving portion 70, and the opposite surface is the back surface. The heating member 110 is a component for dissipating heat. In the fourth embodiment, the heating member 110 emits infrared light for generating heat. For example, the heat generating member 110 for emitting infrared light may be an infrared light emitting diode or an infrared light lamp.

The heat generating member (110) emits infrared light to the protection window (71). Therefore, when the stent plate 15 is located in the stent plate receiving portion 70, the stent 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. At this time, power is supplied to the ultraviolet light emitting diode 40 and the heat generating member 110 by one substrate 42. However, the present invention is not limited to such a structure.

The heating member 110 may be mounted directly on the front surface of the rear portion 51 of the inner casing 50 or may be mounted on a component different from the substrate 42 shown in FIG. Thus, when the ultraviolet light emitting diode 40 and the heat generating member 110 are disposed in different constituent parts, the heat of the heat generating member 110 can be prevented from affecting the ultraviolet light emitting diode 40. A control unit for controlling the heat generating 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 heating member 110 may be operated in conjunction with the ultraviolet light emitting diode 40. [ That is, the heating member 110 may start or stop generating heat in accordance with an on operation for irradiating the ultraviolet light of the ultraviolet light-emitting diode 40 or an off operation for stopping the ultraviolet light irradiation.

In addition, the heat generating member 110 can be operated 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 to irradiate ultraviolet light. Thereafter, the heat generating member 110 generates heat for a predetermined time by the timer, and stops the heat generating operation after a predetermined time.

Further, the heat generating member 110 may receive a signal by the trigger switch described in the previous embodiment, and start or stop the heat generation. 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 perform the role of the trigger switch at the same time. When the stethoscope 1 is mounted on the sterilizing device 3, at least a part of the stethoscope plate fixture 73 is inserted into the interior casing 50 by the stethoscope plate 15, inserted into the interior casing 50, Can return. At this time, a part of the stethoscope plate fixture 73 inserted into the inner casing 50 can transmit a signal to the constituent part (not shown) disposed inside the inner casing 50 by a method such as contact, pressurization or the like. At this time, the component receiving the signal may transmit a signal so that the heat generating member 110 performs the heat generating operation.

On the other hand, when the stethoscope 1 is separated from the sterilizing device 3, at least a part of the stethoscope plate fixture 73 is inserted into the inside and returns to the original position again. At this time, the signal is transmitted to the component arranged inside the inner casing 50, so that the heat generating member 110 stops the heat generating operation.

Further, the heating member 110 can be operated by receiving a signal that the stethoscope 1 is mounted or separated from the sterilizing device 3 from the sensing unit such as the photosensor, the distance measuring sensor, etc. described in the previous embodiment.

The heating member 110 also includes a trigger switch, a stethoscope plate fixture 73 serving also as a trigger switch, and a signal indicating that the stethoscope 1 is mounted or separated from the sterilizing device 3 from two or more of the one or more sensing portions When you receive it, you may start or stop fever.

That is, the heating member 110 may operate by receiving a separate signal from the trigger switch, the stethoscope fixing unit 73, the sensing unit, and the like, not by the signal of the operation of the ultraviolet light emitting diode 40.

In addition, the sterilizing device 3 may further include a temperature sensing means 120. The temperature sensing means 120 controls the heating member 110 so that the temperature of the stenting plate 15 is maintained within a predetermined range. The temperature sensing means 120 can stop the heat generation of the heat generating member 110 if the temperature exceeds the maximum value of the set range. Also, the temperature sensing means 120 may cause the heat generating member 110 to start generating heat if the temperature is less than the minimum value of the set range. Here, the temperature sensed by the temperature sensing means 120 may be the temperature of the stenting plate 15 or the temperature of the space around the heat generating member 110.

The temperature sensing means 120 can prevent the stent plate 15 from being heated too hot or kept cold so that the patient is not harmed or uncomfortable.

The method of starting the heating of the heating member 110 and stopping the heating of the heating member 110 may be applied to the heating member 110 of the following embodiments.

11 to 13 are diagrams showing an example of a sterilizing apparatus for a stethoscope according to a fifth embodiment of the present invention.

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

In the sterilizing apparatus 3 according to the fifth embodiment, the heating member 130 is disposed on the front surface of the protection window 71. [ Here, the front surface of the protection window 71 is a surface located in the stethoscope receiving portion 70. The heating member 130 is formed of a material that generates heat when power is supplied thereto. For example, the heating member 130 may be formed of heat or thermal fibers. A control unit for supplying power to the heating member 130 inside or outside the inner casing 50 and controlling the operation of the heating member 130 may be formed.

When the stethoscope 1 is mounted on the sterilizing device 3, the lower surface of the stethoscope 15 is positioned or brought into close contact with the heating member 130. Here, the lower surface of the stent plate 15 is a surface sterilized by ultraviolet rays. Thus, the heat of the heat generating member 130 can be directly transmitted to the stenting plate 15.

The heating member 130 may be formed at the edge of the protective window 71 as shown in FIG. Or the heating member 130 may be formed in a lattice structure in the protection window 71 as shown in FIG. At this time, ultraviolet rays of the ultraviolet light-emitting diode 40 pass through the protective window 71 where the heat generating member 130 does not exist, and are irradiated to the stethoscope plate 15.

The structure of the heating member 130 shown in FIGS. 12 and 13 is an embodiment, and the structure of the heating member 130 is not limited thereto. The heating member 130 may be formed in various structures as long as a sufficient amount of ultraviolet rays for sterilizing the stent plate 15 can be irradiated to the stent plate 15 through the protective window 71. [

The heating member 130 is disposed on the protection window 71 and the UV light emitting diode 40 is disposed on the back surface portion 51 of the inner casing 50. In this case, . In addition, the heating member 130 and the ultraviolet light emitting diode 40 are located at different heights. Therefore, the heat generating member 130 has a long heat conduction path to the ultraviolet light emitting diode 40. [ It is possible to reduce the influence of the heat generated in the heat generating member 130 by the heat conduction path on the ultraviolet light emitting diode 40, thereby preventing the ultraviolet light emitting diode 40 from being damaged.

14 is an exemplary view showing a sterilizing apparatus for a stethoscope according to a sixth embodiment of the present invention.

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

When the stethoscope 1 is mounted on the sterilizing device 3, the side surface of the stethoscope 15 comes into close contact with or comes into contact with the heating member 140. Therefore, the heat of the heat generating member 140 is transmitted through the side surface of the stenting plate 15, and the stenting plate 150 is heated.

15 is an exemplary view showing a sterilizing apparatus for a stethoscope according to a seventh embodiment of the present invention.

According to the seventh embodiment, the inner casing 50 includes a back surface portion 51, a side surface portion 53, and an insulating portion 150. In this embodiment, the heat generating member 140 is formed on the inner wall of the side portion 53.

The insulating portion 150 is formed between the side surface portion 53 and the back surface portion 51. The insulating portion 150 may be formed of a material having a thermal conductivity different from that of at least one of the side surface portion 53 and the back surface portion 51. For example, the insulating portion 150 is formed of a material having a thermal conductivity lower than that of the side surface portion 53 and the back surface portion 51. The back surface portion 51 and the side surface portion 53 are thermally separated by the insulating portion 150 formed of a material having a low thermal conductivity. Therefore, it is possible to prevent the heat of the heat generating member 140 from being conducted to the back surface portion 51 through the side surface portion 53. Since the back surface portion 51 and the side surface portion 53 are thermally separated from each other, the back surface portion 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 the embodiment of the present invention, the back surface portion 51 and the side surface portion 53 constituting the inner casing 50 may be formed of the same material or different materials. When the back surface portion 51 and the side surface portion 53 are formed of different materials, they may be formed of materials having different thermal conductivities. For example, the side surface portion 53 may be formed of a material having a low thermal conductivity for maintaining the temperature of the stethoscope 1, and the back surface portion 51 may be formed of a material having a high thermal conductivity for dissipating heat of the light emitting diode 40 .

16 is an exemplary view showing an apparatus for sterilizing a stethoscope according to an eighth embodiment of the present invention.

According to the eighth embodiment, the inner casing 50 is made up of the back surface portion 51 and the side surface portion 53. The side surface portion 53 includes a first side surface portion 58, a second side surface portion 59, and an insulating portion 150.

The first side surface portion 58 is in contact with the back surface portion 51 and the second side surface portion 59 is formed in front of the first side surface portion 58. In this 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 portion 150 may be formed of a material having a thermal conductivity different from that of at least one of the first side portion 58 and the second side portion 59. For example, the insulating portion 150 is formed of a material having a thermal conductivity lower than that of the first side portion 58 and the second side portion 59. The first side surface portion 58 and the second side surface portion 59 are thermally separated by the insulating portion 150. That is, the insulating portion 150 prevents the heat of the heat generating member 140 formed on the second side surface portion 59 from being conducted to the first side surface portion 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.

Since the first side surface portion 58 and the second side surface portion 59 are thermally separated from each other, only the first side surface portion 58 and the back surface portion 51 perform 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.

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

According to the embodiment of the present invention, the rear portion 51, the first side portion 58, and the second side portion 59 may be formed of the same material, and at least one may be formed of another material. For example, the second side surface portion 59 is formed of a material having low thermal conductivity for keeping the stethoscope 1 at a low temperature. The back surface portion 51 and the first side surface portion 58 are formed of a material having a high thermal conductivity And may be formed of a material. In addition, if the back surface portion 51 is not integrated with the first side surface portion 58, it may be formed of different materials.

17 is an exemplary view showing a sterilizing apparatus for a stethoscope according to a ninth embodiment of the present invention.

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

A cavity 54 is formed in the back surface portion 51 of the inner casing 50. The cavity 54 is provided with an ultraviolet light emitting diode 40.

FIG. 17 shows a structure in which the substrate 42 is disposed under the cavity 54. FIG. However, the present invention is not limited thereto, and it is also possible that both the substrate 42 and the ultraviolet light emitting diode 40 are disposed in the cavity 54.

Further, a protection window 71 is disposed in the cavity 54. The protection window 71 is located in front of the ultraviolet light emitting diode 40 and one side of the protection window 71 is positioned on a straight line with one side of the back side portion 51. Here, one surface of the protection window 71 and one surface of the back surface portion 51 are the surfaces exposed to the stent plate receiving portion 70. However, the position where the protection window 71 is disposed is not limited thereto. The protection window 71 may be disposed at any position between the UV light emitting diode 40 and the stopper 160.

A heating member 140, a stopper 160, and a trigger switch 74 are formed on the side surface portion 53 of the inner casing 50.

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

The stopper 160 is for separating the stent plate 15 from the ultraviolet light emitting diode 40 and the back surface portion 51 when the stethoscope 1 is mounted on the sterilizing device 3. [ When the stent plate 15 is located too close to the ultraviolet light emitting diode 40, ultraviolet rays are not irradiated to the entire lower surface of the stent plate 15. [ Therefore, in order to irradiate ultraviolet rays to the entire bottom surface of the stent plate 15, a spacing space is required between the stenting plate 15 and the ultraviolet light emitting diode 40. When the stent plate 15 is brought into contact with the back surface portion 51, ultraviolet rays are not irradiated to portions of the lower surface of the stent plate 15 that are in contact with the back surface portion 51. Therefore, the stenting plate 15 should be separated from the ultraviolet ray backing part 51 as well.

The trigger switch 74 is for detecting that the stethoscope 1 is attached to the sterilizing device 3. [ Instead of the trigger switch 74, it is possible to apply any of the sensing units described in the previous embodiments.

Further, in this embodiment, the heat generating member 140 is formed on the side surface portion 53 as an example. However, it is also possible that the heat generating member 140 is formed on one surface of the back surface portion 51 or both of the side surface portion 53 and the back surface portion 51.

In this embodiment, it is also possible to omit the protection window 71 according to the selection of a person skilled in the art.

18 is an exemplary view showing a sterilizing apparatus for a stethoscope according to a tenth embodiment of the present invention.

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

As described above, when the stethoscope 1 is attached to the sterilizing device 3 by the stopper 160, ultraviolet rays can be irradiated to the entire lower surface of the stethoscope plate 15. [ Since the UV light emitting diode 40 is not in contact with the stent plate 15 by the stopper 160, the protective window 71 is omitted can do.

Also, the substrate 42 and the ultraviolet light-emitting diode 40 are disposed on the front surface of the rear portion 51, which is also applicable to the present embodiment.

19 and 20 are diagrams illustrating an example of a sterilizing apparatus for a stethoscope according to an eleventh embodiment of the present invention.

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

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

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

A portion of the protective window 71 and the heating member 130 is disposed between the first side portion 58 and the second side portion 59. That is, the present embodiment has a structure in which the first side surface portion 58, the protection window 71, the heating member 130, and the second side surface portion 59 are laminated.

Since the protection window 71 is formed of a material having a low thermal conductivity, the first side surface portion 58 and the second side surface portion 59 are thermally separated. Or the heat generating member 130 and the first side surface portion 58 are thermally separated from each other. That is, it is possible to prevent the heat of the heating member 130 from being transmitted to the first side surface portion 58 by the protection window 71 and affecting the ultraviolet light-emitting diode 40.

The heat generating member 130 is disposed between the first side surface portion 58 and the second side surface portion 59 in the present embodiment. 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 on the front surface of the protective window 71 in the stent plate accommodating portion 70 It is also possible. Or the heat generating member 130 may be formed on the inner wall of the second side surface portion 59.

The outer casing 60 is formed to enclose the outer surface 56 of the inner casing 50 and a part of the front surface 55. That is, the outer casing 60 is formed to surround a part of the front surface of the second side surface portion 59 and the outer side surfaces of the first side surface portion 58 and the second side surface portion 59. The first side surface portion 58, the second side surface portion 59, the protection window 71 and the heat generating member 130 are fixed by the outer casing 60 so as not to be separated from each other without a separate adhesive material. In addition, heat from the heat generating member 130 is prevented from being discharged to the outside by the outer casing 60, and the heating efficiency of the stuttering plate 15 is improved. Here, the portion of the outer casing 60 surrounding the front surface 55 of the inner casing 50 corresponds to the shielding portion (64 in Fig. 3). As shown in FIG. 3, a plurality of shielding portions 64 may be formed and spaced apart from each other. Also, although not shown, the shielding portion 64 may be formed continuously along the front surface 55 of the inner casing 50. The detailed description and the effect of the shielding portion 64 will be described with reference to FIG.

The outer casing 60 is formed to expose the rear surface of the back surface portion 51 of the inner casing 50 to the outside. Therefore, since the back surface portion 51 can directly discharge the heat of the ultraviolet light-emitting diode 40 to the outside, the heat radiation effect of the sterilizing device 3 can be improved.

FIG. 21 is an exemplary view showing a sterilizing apparatus for a stethoscope according to a twelfth embodiment of the present invention. FIG.

21, the outer casing 60 is formed so as to surround a part of the outer surface 56 of the inner casing 50 and a part of the front surface 55. That is, the outer casing 60 includes a portion of the front surface of the second side surface portion 59, an outer surface of the second side surface portion 59, a protective window 71, a portion of the outer surface of the heat generating member 130 and the first side surface portion 58 As shown in FIG.

The first side portion 58, the second side portion 59, the protection window 71 and the heat generating member 130 are fixed by the outer casing 60 so as not to be separated from each other without a separate adhesive material. Further, since the heat of the heat generating member 130 is prevented from being discharged to the outside by the outer casing 60, the heating efficiency of the stuttering plate 15 is improved.

The outer casing 60 is formed to expose a part of the outer side surface of the first side surface portion 58 and a rear surface of the back surface portion 51 to the outside. Therefore, the first side surface portion 58 and the back surface portion 51 can directly radiate the heat of the ultraviolet light-emitting diode 40 to the outside through the externally exposed portion. Therefore, the heat radiation effect of the sterilizing device 3 can be improved.

Although not shown in FIGS. 1 to 21, a reflective member for reflecting ultraviolet light may be further formed on the inner surface of the inner casing or the inner surface of the cavity. The reflection member can prevent the ultraviolet rays emitted from the ultraviolet light emitting diode from being absorbed and lost by the inner casing, thereby increasing the sterilizing efficiency of the sterilizing apparatus.
