Description

  The present invention relates to an incubator for providing a suitable physiological environment for a newborn who cannot adjust body temperature or the like by his / her own power to protect and nurture the newborn.

  The incubator is provided with a newborn accommodation room that provides a suitable physiological environment for the newborn. In the closed type incubator, not only the temperature but also the humidity and oxygen concentration are controlled in the neonatal chamber enclosed by the side walls and the ceiling. Even in an open type incubator, a side wall is provided in the newborn chamber to prevent falling of the newborn in the newborn chamber, heat insulation, etc., and a bed in the newborn chamber is provided by a heat ray radiation source disposed above the newborn chamber. The temperature of the table and the body temperature of the newborn baby are controlled. In addition, there is a switchable incubator in which the ceiling of the newborn housing chamber is separated from the side wall and can be switched at any time between a closed type incubator and an open type incubator by raising and lowering the ceiling.

  When various treatments are performed on a newborn housed in the newborn accommodation chamber of such an incubator, it may be necessary to illuminate the newborn to improve the visibility of the newborn. For this reason, conventionally, when performing the above-described treatment, an illumination light source is attached to the incubator and positioned above the newborn accommodation chamber, and the newborn in the newborn accommodation chamber is placed outside the newborn accommodation chamber with this illumination light source. Illuminated (for example, Patent Document 1 and Patent Document 2). That is, conventionally, the incubator does not have a built-in illumination light source, and the incubator and the illumination light source are separate from each other.

  However, if the incubator and the illumination light source are separate from each other as in the above-mentioned Patent Documents 1 and 2, prior to the illumination, the neonatal storage chamber is appropriately designed so that the newborn in the newborn storage chamber is appropriately illuminated. Since it is necessary to position the illumination light source at an appropriate position every time, the work of a treatment person such as a doctor or a nurse is complicated. In addition, it is necessary to move the illumination light source prior to this treatment so that the illumination light source does not interfere with the treatment that does not require illumination. In addition to the power source for the incubator, a power source for the illumination light source is also required, which increases the construction cost of the medical facility.

  Furthermore, since the ceiling of the newborn storage room is generally curved, if an illumination light source separate from the incubator is positioned above the newborn storage room, the incubator in which the newborn to be illuminated is stored The light from the illumination light source easily reaches not only the inside but also the newborn in the incubator near the incubator after reflection on the outer surface of the ceiling of the newborn accommodation room. Since the light from the illumination light source causes stress on newborns that are not subject to illumination, work is required to prevent this stress. Therefore, the present invention provides an incubator that requires less work for a treatment person and does not increase the cost of constructing a medical facility when a newborn baby in the incubator is subjected to a treatment that requires illumination or a treatment that does not require illumination. It is aimed.

  In the incubator according to the first aspect, the illumination light source is fixed to the outer surface of the ceiling of the newborn accommodation room. For this reason, it is not necessary to position the illumination light source at an appropriate position with respect to the newborn accommodation chamber every time prior to the treatment requiring illumination. Also, it is not necessary to move the illumination light source prior to this treatment so that the illumination light source does not interfere with treatments that do not require illumination. In addition, since the power supplied to the incubator can be supplied to the illumination light source, a power source only for the illumination light source is unnecessary.

  Furthermore, the area | regions other than the opposing part with the outer surface of the ceiling of a newborn accommodation chamber among the light sources for illumination are light-shielded. Therefore, the light from the illumination light source reaches the newborn in the incubator near the incubator in which the newborn that is the subject of the treatment requiring illumination is reflected on the outer surface of the ceiling of the newborn accommodation room. Without doing so, the work for preventing the stress caused by the light from the illumination light source may be small.

  In the incubator according to the second, fourth, and fifth aspects, since the desired illuminance by the illumination light source can be set by the illuminance setting adjustment unit, the newborn can be illuminated with appropriate illuminance. Also, since the illuminance setting adjustment unit adjusts the luminance of the illumination light source to the luminance corresponding to the most recently set desired illuminance, the treatment person sets the desired illuminance every time using the illumination light source with the illuminance setting adjustment unit There is no need to do.

  In the incubator according to the third, fourth, and fifth aspects, if the desired illuminance by the illumination light source is not set by the illuminance setting adjusting unit, the illuminance setting adjusting unit sets the predetermined illuminance to the desired illuminance. For this reason, it is not always necessary for the treatment person to set the illuminance at the illuminance setting adjustment unit when using the illumination light source.

  In the incubator according to claim 6, the illuminance meter is disposed in the neonatal chamber and connected to the illuminance setting adjustment unit, and the luminance of the illumination light source is adjusted so that the output of the illuminance meter becomes equal to the desired illuminance. The illuminance setting adjuster adjusts. For this reason, even if the actual illuminance in the newborn accommodation chamber by the illumination light source fluctuates for some reason from the desired illuminance, illumination with the desired illuminance is performed automatically.

  In the incubator according to claim 7, when the ceiling of the neonatal chamber is raised or lowered in the switchable incubator, the luminance of the illumination light source is set to the luminance corresponding to the desired illuminance in each state. The adjuster adjusts. For this reason, even if the switching type incubator is switched between the closed type incubator and the open type incubator, it is not necessary for the treatment person to set the desired illuminance by the illumination light source at the illuminance setting adjustment unit every time.

  In the incubator according to the eighth to tenth aspects, since the irradiation range adjusting unit that adjusts the irradiation range by the illumination light source is provided, only the necessary range of illumination can be irradiated by the illumination light source. For this reason, it is difficult for the light from the illumination light source to reach the newborn in the incubator in the vicinity of the incubator in which the newborn that is the subject of the illumination is accommodated, and to prevent stress due to this light Less work is required.

  In the incubator according to claim 11, the irradiation range setting unit can set a desired irradiation range by the light source for illumination, and operates the irradiation range adjustment unit based on the desired irradiation range set most recently. Let For this reason, it is not necessary for the treatment person to adjust the irradiation range every time when the illumination light source is used.

  In the incubator according to the twelfth aspect, if the desired irradiation range is not set by the irradiation range setting unit, the irradiation range setting unit sets the predetermined irradiation range as the desired irradiation range. For this reason, when using the illumination light source, the treatment person does not necessarily need to set the irradiation range in the irradiation range setting unit.

  In the incubator according to claim 13, when the ceiling of the neonatal chamber is raised or lowered in the switchable incubator, the irradiation range by the illumination light source is set to the desired irradiation range in each of these states. Adjust. For this reason, even if the switching type incubator is switched between the closed type incubator and the open type incubator, it is not necessary for the treatment person to set the irradiation range by the illumination light source at the irradiation range setting unit every time.

  In the incubator according to claim 1, it is not necessary to position the light source for illumination at an appropriate position with respect to the newborn accommodation room every time prior to the treatment requiring illumination, and the light source for illumination is provided prior to the treatment not requiring illumination. There is no need to move, and there is little work to prevent stress from light from the light source for the newborn in the incubator near the incubator where the newborn that is the subject of the treatment requiring illumination is housed. Therefore, it is possible to reduce the work of the operator when performing a treatment requiring illumination or a treatment not requiring illumination on the newborn in the incubator. In addition, since a power source only for the illumination light source is unnecessary, the construction cost of the medical facility does not increase.

  In the incubator according to the second, fourth, and fifth aspects, since the newborn can be illuminated with an appropriate illuminance, the optimum treatment can be performed on the newborn. In addition, since it is not necessary for the treatment person to set a desired illuminance at the illuminance setting adjustment unit every time the light source for illumination is used, the work of the treatment person is further reduced when performing a treatment requiring illumination on the newborn in the incubator. It's okay.

  In the incubator according to claims 3, 4 and 5, the treatment person does not necessarily need to set the illuminance by the illuminance setting adjustment unit when using the illumination light source, so the newborn in the incubator is subjected to a treatment requiring illumination. In some cases, the operator's work may be further reduced.

  In the incubator according to claim 6, since the illumination with the desired illuminance is automatically performed even if the actual illuminance in the newborn housing chamber due to the illumination light source fluctuates for some reason from the desired illuminance, When a newborn baby is subjected to a procedure requiring lighting, the operator's work may be further reduced.

  In the incubator according to claim 7, even if the switching type incubator is switched between the closed type incubator and the open type incubator, it is necessary for the treatment person to set a desired illuminance by the illumination light source at the illuminance setting adjustment unit every time. Therefore, it is possible to further reduce the work of the operator when performing a treatment requiring illumination on the newborn in the incubator.

  In the incubator according to claims 8 to 10, it is difficult for the light from the illumination light source to reach the newborn in the incubator in the vicinity of the incubator in which the newborn that is the target of the treatment requiring illumination is accommodated. Since the work for preventing stress due to light may be small, the work of the operator may be further reduced when performing a treatment requiring illumination on the newborn in the incubator.

  In the incubator according to the eleventh aspect, it is not necessary for the treatment person to adjust the irradiation range every time when the light source for illumination is used. Less.

  In the incubator according to the twelfth aspect, the treatment person does not necessarily set the irradiation range in the irradiation range setting unit when using the illumination light source. The person's work may be further reduced.

  In the incubator according to claim 13, even if the switchable incubator is switched between the closed incubator and the open incubator, it is necessary for the treatment person to set the irradiation range by the illumination light source every time in the irradiation range setting unit. As a result, the operator's work may be further reduced when a newborn baby in the incubator is subjected to a treatment requiring illumination.

Another pair of left and right struts 32 (FIG. 3) are nested in the pair of left and right struts 31 so that each strut 32 can slide in each strut 31.

  The ceiling 26 and the infrared heater 33 of the newborn housing chamber 16 are supported by one and the other of the pair of left and right columns 32, respectively. Can be raised and lowered independently of each other. This raising / lowering is performed by a doctor, a nurse, or the like giving an operation instruction to a drive mechanism such as an electric motor (not shown). An operation / display panel 34 is attached to one of the left and right support columns 31. The operation / display panel 34 has an illumination light on / off switch 35, a phototherapy device on / off switch 36, and an illuminance setting. A switch 37 and an irradiation range setting switch 38 are provided. The support 31 is also provided with a protector 41 that prevents the infrared heater 33 from colliding with a wall surface (not shown) of the room.

  FIG. 1 shows a ceiling 26 and its vicinity in the incubator 11 according to the first embodiment of the present invention. A support arm 42 is attached to one of the left and right support columns 32, and the ceiling 26 is suspended from a support shaft 43 of the support arm 42. A pair of elastic supports 44, 45 are attached to the support arm 42, and the elastic supports 44, 45 press the ceiling 26, thereby rotating the ceiling 26 around the support shaft 43 within a predetermined angular range. Restricted to As the structure of the elastic supports 44 and 45, for example, a structure in which a rubber hemispherical pressing portion is attached to the tip of the compression coil spring is conceivable. In the vicinity of the elastic support 44, an illumination light source 46 and a light treatment light source 47 (FIGS. 6 and 7) are fixed to the outer surface of the ceiling 26, and the support arm 42, the illumination light source 46, the light treatment light source 47, etc. Is covered with an opaque cover 48.

  FIGS. 6-8 has shown the light source 46 for illumination, the light source 47 for phototherapy, and those vicinity parts. The illumination light source 46 and the phototherapy light source 47 are arranged in the left-right direction of the newborn baby 22 on the bed table 21, and each has one light source unit 51. Both the illumination light source 46 and the light treatment light source 47 are fixed to the outer surface of the ceiling 26 via the diaphragm mechanism 52. The illumination light source 46 and the light therapy light source 47 are displaced from the center of the bed 21 in the neonatal chamber 16, and the illumination light source 46 and the light therapy light source 47 are centered on the center of the bed 21. In order to perform irradiation, the light source units 51 of the illumination light source 46 and the light treatment light source 47 are inclined with respect to the outer surface of the ceiling 26.

  As shown in FIG. 9, the aperture mechanism 52 includes a gear 53, a rack 54, and an actuator 55. When the actuator 55 is actuated, the rack 54 is linearly driven, and the gear 53 is rotated by the linear drive. By this rotation, the opening 56 in the aperture mechanism 52 is shown as shown in FIGS. The size of is adjusted. A worm may be used in place of the rack 54. In this case, the gear 53 is rotated by rotational driving of the worm. A stepping motor may be used instead of the actuator 55. The size of the opening 56 in the aperture mechanism 52 is controlled by position detection by a linear potentiometer (not shown) or an encoder (not shown).

  The light shielding guide cover 57 of the light source unit 51 is fixed on the diaphragm mechanism 52, and the LED 62 fixed to the substrate 58 and covered with the diffusing lens 61 as shown in FIG. Has been placed. A diffusion lens 63 other than the diffusion lens 61 is also disposed in the light shielding guide cover 57. In the illumination light source 46 and the light treatment light source 47, a region other than the portion facing the outer surface of the ceiling 26, that is, a region other than the opening 56 of the diaphragm mechanism 52 is shielded from light. As shown in FIGS. 4 and 5, an illuminance meter 64 is disposed in the vicinity of the newborn baby 22 on the upper surface of the bedtop 21. The illuminometer 64 measures both the illuminance as the photometric quantity and the spectral irradiance as the radiation amount, and outputs these measured values to the operation / display panel 34.

  In the incubator 11 according to the first embodiment as described above, the operation / display panel 34 is used when illumination is necessary to perform phototherapy or other treatment on the newborn 22 accommodated in the newborn accommodation room 16. The illumination lamp on / off switch 35 is turned on, and the illuminance setting switch 37 is pressed. Since the illuminance setting screen (not shown) is displayed on the operation / display panel 34 by this pressing, the illuminance setting of the illumination light source 46 is selected on this illuminance setting screen, and the illuminance setting screen of the displayed illumination light source 46 is displayed. Then, a desired illuminance (unit: lx) at a predetermined distance (for example, 30 cm) from the illumination light source 46 is set. The latest set value is stored in the operation / display panel 34.

  The desired illuminance may be set at a stage such as high, low, high, medium, low, etc. instead of being directly set as a numerical value. Further, instead of the illumination lamp on / off switch 35, the illumination setting switch 37, and the illumination setting screen displayed on the operation / display panel 34, a dial for sequentially setting the illumination lamp on / off and illumination is used. May be.

  The operation / display panel 34 adjusts the power supplied to the LED 62 of the light source unit 51 of the illumination light source 46, specifically the voltage, current, pulse duty ratio, and the like by the above setting, and stores the desired The illumination light source 46 is adjusted so as to obtain a luminance corresponding to the illuminance. If the desired illuminance setting itself by the illumination light source 46 has not been set yet and the desired illuminance setting value by the illumination light source 46 is not stored in the operation / display panel 34, the operation / display panel 34 is the default. The luminance of the illumination light source 46 is adjusted by setting the illuminance (approximately 600 lx) to a desired illuminance.

  The operation / display panel 34 automatically adjusts the luminance of the illumination light source 46 so that the illuminance output from the illuminometer 64 becomes equal to the desired illuminance. Accordingly, when the state of the incubator 11 is changed from the state of the closed type incubator shown in FIGS. 2 and 4 to the state of the open type incubator shown in FIGS. In this case, the operation / display panel 34 automatically increases the luminance of the illumination light source 46 until the illuminance output from the illuminometer 64 becomes equal to the desired illuminance. Conversely, when the state of the incubator 11 is changed from the state of the open type incubator to the state of the closed type incubator, the operation / display panel 34 automatically reduces the luminance of the illumination light source 46.

  In order to set a desired irradiation range of light emitted from the illumination light source 46, the irradiation range setting switch 38 of the operation / display panel 34 is pressed. Since the irradiation range setting screen (not shown) is displayed on the operation / display panel 34 by this pressing, the irradiation range setting of the illumination light source 46 is selected on the irradiation range setting screen, and the displayed illumination light source 46 is displayed. A desired irradiation range is set on the irradiation range setting screen. When the desired irradiation range by the illumination light source 46 is changed, the operation / display panel 34 operates the diaphragm mechanism 52.

  For the irradiation range by the illumination light source 46, the latest set values in the closed incubator state and the open incubator state are stored in the operation / display panel 34. For this reason, if the state of the incubator 11 is changed between the state of the closed type incubator and the state of the open type incubator, the irradiation range by the illumination light source 46 is also automatically changed. If the setting value of the desired irradiation range by the illumination light source 46 is not stored in the operation / display panel 34, the operation / display panel 34 is a default in the state of the closed type incubator and the state of the open type incubator. The irradiation range of the illumination light source 46 is adjusted by setting the irradiation range to a desired irradiation range.

On the other hand, when the newborn baby 22 on the bed 21 is hyperbilirubinemia and phototherapy is performed on the newborn baby 22, the phototherapy device on / off switch 36 of the operation / display panel 34 is turned on, and the illuminance is further increased. Press the setting switch 37. Since the illuminance setting screen (not shown) is displayed on the operation / display panel 34 by this pressing, the illuminance setting of the light therapy light source 47 is selected on this illuminance setting screen, and the illuminance of the displayed light therapy light source 47 is displayed. On the setting screen, a desired spectral irradiance (unit: μW / cm ² / nm) at a predetermined distance (for example, 30 cm) from the light therapy light source 47 is set. The latest set value is stored in the operation / display panel 34.

  Note that the desired spectral irradiance may be set at a stage such as high, low, high, medium, low, etc. instead of being directly set as a numerical value. Further, instead of the phototherapy device on / off switch 36, the illuminance setting switch 37, and the illuminance setting screen displayed on the operation / display panel 34, the phototherapy device on / off and the spectral irradiance are sequentially set. A dial may be used.

  According to the above settings, the operation / display panel 34 adjusts and stores the power supplied to the LED 62 of the light source unit 51 of the light therapy light source 47, specifically the voltage, current, pulse duty factor, etc. The light therapy light source 47 is adjusted so that the spectral radiance corresponding to the desired spectral irradiance is obtained. If the desired spectral irradiance setting by the light therapy light source 47 has not yet been set and the desired spectral irradiance setting value by the light therapy light source 47 is not stored in the operation / display panel 34, the operation / display panel 34 The display panel 34 adjusts the spectral radiance of the light therapy light source 47 by setting the predetermined spectral irradiance to a desired spectral irradiance.

The spectral irradiance required for phototherapy is 35 μW / cm ² / nm or more, but the light emitted from the phototherapy light source 47 contains a large amount of ultraviolet components, causing damage to the eyes of the newborn 22. there is a possibility. For this reason, an eye mask is attached to the newborn baby 22 during phototherapy, and the above-mentioned predetermined spectral irradiance is set to 10 μW / cm ² / nm or less in consideration of forgotten wearing. Further, even when the stored set value is 10 μW / cm ² / nm or more, the spectral radiance of the light therapy light source 46 is gradually increased from the spectral radiance corresponding to the spectral irradiance of 10 μW / cm ² / nm or less. To increase.

  The operation / display panel 34 automatically adjusts the spectral radiance of the light therapy light source 47 so that the spectral irradiance output from the illuminometer 64 becomes equal to the desired spectral irradiance. Accordingly, when the state of the incubator 11 is changed from the state of the closed type incubator shown in FIGS. 2 and 4 to the state of the open type incubator shown in FIGS. In this case, the operation / display panel 34 emits the spectral radiation of the light therapy light source 47 until the spectral irradiance output from the illuminometer 64 becomes equal to the desired spectral irradiance. Increase brightness automatically. Conversely, when the state of the incubator 11 is changed from the open type incubator state to the closed type incubator state, the operation / display panel 34 automatically reduces the spectral radiance of the light therapy light source 47.

  In order to set a desired irradiation range of light emitted from the light therapy light source 47, the irradiation range setting switch 38 of the operation / display panel 34 is pressed. Since the irradiation range setting screen (not shown) is displayed on the operation / display panel 34 by this pressing, the irradiation range setting of the light therapy light source 47 is selected on the irradiation range setting screen, and the displayed light therapy light source is displayed. A desired irradiation range is set on the irradiation range setting screen 47. When the desired irradiation range by the light therapy light source 47 is changed, the operation / display panel 34 operates the aperture mechanism 52.

  As for the irradiation range by the light therapy light source 47, the latest set values in the closed incubator state and the open incubator state are stored in the operation / display panel 34. For this reason, when the state of the incubator 11 is changed between the state of the closed type incubator and the state of the open type incubator, the irradiation range by the light therapy light source 47 is also automatically changed. If the setting value of the desired irradiation range by the phototherapy light source 47 is not stored in the operation / display panel 34, the operation / display panel 34 is in the closed incubator state and the open incubator state, respectively. The irradiation range of the light source for phototherapy 47 is adjusted by setting the predetermined irradiation range to a desired irradiation range.

  In the incubator 11 of Example 1 described above, as shown in FIGS. 6 and 7, the illumination light source 46 and the light treatment light source 47 are arranged in the left-right direction of the newborn baby 22 on the bed 21. However, the illumination light source 46 and the light therapy light source 47 may be arranged in the height direction of the newborn baby 22 on the bed 21. The light therapy light source 47 is not necessarily provided.

  12-14 has shown the light source 46 for illumination in the incubator 11 of Example 2 of this invention, the light source 47 for light therapy, and those vicinity parts. In the second embodiment, the illuminance adjustment and irradiation range adjustment of the illumination light source 46 and the phototherapy light source 47 are performed manually instead of automatically. Accordingly, the illuminance meter 64 is not disposed on the upper surface of the bed 21, and the diaphragm mechanism 52 for the illumination light source 46 and the diaphragm mechanism 52 for the light treatment light source 47 include a gear 53, a rack 54, and an actuator 55. Is not provided, and the operation / display panel 34 is not provided with the irradiation range setting switch 38. Instead, the throttle mechanism 52 is provided with an adjustment lever 65, and an opening 66 is provided in the cover 48 for projecting the adjustment lever 65 from the inside of the cover 48 to the foot side of the newborn baby 22 on the bed 21. Yes.

  In the incubator 11 of Example 2 as described above, the desired illuminance by the illumination light source 46 and the desired spectral irradiance by the light therapy light source 47 are set on the operation / display panel 34, and the most recent set values and The state of the incubator 11 when these settings are made, that is, whether it is a closed type incubator or an open type incubator is stored in the operation / display panel 34. With the above settings, the operation / display panel 34 adjusts the luminance of the illumination light source 46 and the spectral radiance of the light therapy light source 47. If the setting value of the desired illuminance by the illumination light source 46 or the desired spectral irradiance by the light therapy light source 47 is not stored in the operation / display panel 34, the predetermined illuminance or spectral radiation corresponding to the state of the incubator 11 is stored. The illuminance is set to a desired illuminance or spectral irradiance.

  Therefore, when the state of the incubator 11 is changed between the state of the closed type incubator and the state of the open type incubator, the luminance of the illumination light source 46 and the spectral radiance of the light therapy light source 47 are manipulated and displayed. Automatically adjusted by panel 34. However, in order to adjust to the desired illuminance or spectral irradiance when the actual illuminance or spectral irradiance in the neonatal chamber 16 fluctuates for some other reason, the desired illuminance or light beam by the illumination light source 46 is used. It is necessary to reset the desired spectral irradiance by the treatment light source 47 on the operation / display panel 34.

  In order to adjust the irradiation range of the light emitted from the illumination light source 46 or the light treatment light source 47, as shown by the solid line and the alternate long and short dash line in FIG. By manually rotating the adjusting lever 65, the size of the opening 56 in the aperture mechanism 52 is adjusted as shown in FIGS. Therefore, when the state of the incubator 11 is changed between the state of the closed type incubator and the state of the open type incubator, the irradiation range by the light source for illumination 46 and the light source for light therapy 47 also varies. Therefore, it is necessary to adjust the irradiation range by the illumination light source 46 and the light treatment light source 47 by manually rotating the adjustment lever 65.

  In the incubator 11 of Example 2 described above, as shown in FIGS. 12 and 13, the illumination light source 46 and the phototherapy light source 47 are arranged in the left-right direction of the newborn baby 22 on the bed 21. However, the illumination light source 46 and the light therapy light source 47 may be arranged in the height direction of the newborn baby 22 on the bed 21. In this case, the adjustment lever 65 for the illumination light source 46 or the adjustment lever 65 for the light treatment light source 47 located on the head side of the newborn baby 22 on the bed 21 has the shape of the cover 48 shown in FIGS.
