  The thickness of the sheet-like member 51 is, for example, 0.1 mm to 0.3 mm. A predetermined nameplate can be affixed or printed on the surface of the PET layer on the base material layer side. The sheet-like member 51 can be manufactured by cutting or the like. The sheet-like member 51 is configured to be substantially tapered so that the width gradually decreases toward the side where the thermistor 10 is disposed (probe portion 82 side).

  The sheet-like member 51 is provided with an opening 51H for visually recognizing the display panel 31 from the outside. A transparent protective member 56 made of resin or the like is disposed in the opening 51H. In addition, when the sheet-like member 51 has transparency, the opening 51H and the transparent protective member 56 are unnecessary. The opening 51H for visually recognizing the display panel 31 from the outside may be provided in the case body 52 described below. In this case, the display unit 30 is provided so as to be exposed on the back side of the substrate 29, and the display panel 31 is disposed toward the case body 52 side.

  The case body 52 is configured in a container shape by vacuum molding or the like from a thermoplastic member such as PET, PVC (polyvinyl chloride), PE (polyethylene), or PP (polypropylene). The thickness of the case body 52 is, for example, 0.5 mm to 1.0 mm.

The upper end portion 52K in the present embodiment extends in a flange shape from the tip in the standing direction of the annular wall portion 52U toward the outside of the case body 52, and has an annular shape as a whole.

  The bottom surface portion 52S is located on one end side (front end side) of the electronic thermometer 100 and has a substantially concave shape in cross-sectional view (see FIG. 4). The bottom surface portion 52R is continuous with the bottom surface portion 52S and is located on the other end side (rear end side) of the electronic thermometer 100. The bottom surface portion 52S is formed shallower than the bottom surface portion 52R so that the electronic thermometer 100 can be easily inserted toward the measurement subject's armpit or tongue.

  When the electronic thermometer 100 is assembled, the built-in package 95 is disposed on the bottom surface portions 52S and 52R of the case body 52. Specifically, the tip 92U of the bag-like member 92 that accommodates the thermistor 10 (the temperature sensing part 11 and the lead wire 12) is disposed on the bottom face part 52S. The rear end (joining portion 92V) side of the bag-like member 92 that accommodates the control substrate 20, the display unit 30, the power supply unit 40, and the substrate 29 is disposed on the bottom surface portion 52R. In this state, the sheet-like member 51 is joined to the upper end portion 52K of the case body 52. By the bonding, a space 53 (see FIG. 4) in which the built-in package 95 is sealed in a substantially airtight manner is formed.

  In order to join the sheet-like member 51 and the upper end portion 52K to each other, the sheet-like member 51 and the upper end portion 52K of the case body 52 are arranged to face each other. In this state, ultrasonic waves are applied to the contact portion between the sheet-like member 51 and the upper end portion 52K. The sheet-like member 51 (such as a sealant layer) is temporarily dissolved by the applied ultrasonic waves. By the melting, the sheet-like member 51 is welded (crimped) to the upper end portion 52K of the case body 52. The sheet-like member 51 and the upper end portion 52K of the case body 52 may be joined by heat welding or an adhesive.

  As shown in FIG. 4, the temperature sensing part 11 and at least a part of the inner surface 92S of the bag-like member 92 are preferably in contact with each other (in this embodiment, two locations indicated by reference numerals 92S and 92S). , The temperature sensing part 11 and the inner surface 92S are in contact with each other). Furthermore, the outer surface 92T of the bag-like member 92 corresponding to the inner surface 92S with which the temperature sensing part 11 is in contact is formed on the inner peripheral surface 51S of the sheet-like member 51 or the bottom surface portion 52S (inner peripheral surface) of the case body 52. It should be in contact. According to this configuration, heat transfer from the housing 50 (the sheet-like member 51 or the case body 52) and the bag-like member 92 (the tip 92U) to the temperature-sensing unit 11 is enhanced, and the heat-responsiveness in the temperature-sensing unit 11 is improved. Can be made.

  With reference to FIG. 5, as described above, the electronic thermometer 100 includes the temperature sensing unit 11, the operation unit 21, the control unit 22, the memory unit 23, the notification unit 24, the display unit 30, and the power supply unit 40.

The power supply unit 40 includes, for example, a button battery 42 (see FIG. 1) and supplies power as a power source to the control unit 22.

  The control unit 22 includes a processing circuit for performing body temperature measurement, and measures body temperature based on a program read from the memory unit 23. At that time, the control unit 22 calculates the body temperature as the measurement result by processing the temperature data input from the temperature sensing unit 11. The control unit 22 displays the calculated body temperature on the display unit 30, stores the calculated body temperature in the memory unit 23, or notifies the measurement subject that the measurement is completed using the notification unit 24. Next, the electronic thermometer 100 is controlled.

(Action / Effect)
The housing 50 of the electronic thermometer 100 is simply composed of a sheet-like member 51 and a case body 52. The sheet-like member 51 is an extremely thin member made of PET or the like. Since the sheet-like member 51 is thin and manufactured by cutting or the like, it can be prepared at low cost. Since the case body 52 is also an extremely thin member made of PET or the like by vacuum molding or the like, it can be prepared at a low cost. According to the electronic thermometer 100, the manufacturing cost can be reduced compared to a general so-called pencil-type electronic thermometer in which the entire casing is made of molded resin.

  Since the electronic thermometer 100 is manufactured at low cost, the electronic thermometer 100 is suitable for being used as a so-called disposable type. If it is a disposable type, it is discarded every time the electronic thermometer 100 is used (or every predetermined number of times of use), for example, at a medical site. According to the electronic thermometer 100, it is possible to reduce the cost burden on the user side or the person to be measured that occurs at each disposal.

  Moreover, the housing 50 of the electronic thermometer 100 deteriorates by using the electronic thermometer 100 repeatedly. When the body temperature of an infectious disease patient or the like is measured using the electronic thermometer 100, pathogenic bacteria or the like may adhere to the housing 50 (probe unit 82) of the electronic thermometer 100. When the housing 50 deteriorates or a pathogen or the like adheres to the housing 50, in the electronic thermometer 100, only the housing 50 can be replaced and the built-in package 95 can be reused.

  In the built-in package 95, the thermistor 10, the control substrate 20, the display unit 30, the power supply unit 40, and the substrate 29 are integrated by a bag-shaped member 92. The electronic thermometer 100 is highly convenient when the housing 50 is replaced and the built-in package 95 is reused. The internal package 95 may be reused after the surface of the bag-like member 92 is washed with ethanol or the like.

  Even if water or the like enters the housing 50, the thermistor 10, the control board 20, the display part 30, the power supply part 40, and the board 29 are covered with the bag-like member 92 in the built-in package 95. According to the electronic thermometer 100, it is possible to suppress the failure of these built-in devices (built-in device 18) due to water intrusion. Note that it is also possible to measure the body temperature of the measurement subject (without using the housing 50) using only the built-in package 95 as necessary.

  As described above, the temperature sensing part 11 is in contact with at least a part of the inner surface 92S of the bag-like member 92, and further, the outer surface of the bag-like member 92 corresponding to the inner surface 92S with which the temperature sensing part 11 is in contact. 92T may be in contact with the inner peripheral surface 51S of the sheet-like member 51 or the bottom surface portion 52S (inner peripheral surface) of the case body 52 (see FIG. 4). According to this configuration, heat transfer from the housing 50 (the sheet-like member 51 or the case body 52) and the bag-like member 92 (the tip 92U) to the temperature-sensing unit 11 is enhanced, and the heat-responsiveness in the temperature-sensing unit 11 is improved. Can be made.

  The inside of the bag-like member 92 is preferably filled with a gas (air or the like) so that the inside of the bag-like member swells. In other words, the bag-like member 92 is preferably filled with gas so that the internal pressure of the bag-like member 92 is higher than the external pressure of the bag-like member 92. According to this configuration, for example, when the electronic thermometer 100 is dropped, the devices (the control board 20, the display unit 30, or the power supply unit) inside the built-in package 95 are generated by the elasticity generated by the pressure of the gas filled in the bag-like member 92. 40 etc.) is mitigated.

  In addition, a predetermined protrusion may be formed due to breakage of a device (the control board 20, the display unit 30, or the power supply unit 40) inside the built-in package 95. In this case, the protrusions make a hole in the bag-like member 92 from the inside of the bag-like member 92, and the air filled inside leaks out. A user or the like of the electronic thermometer 100 notices that the air in the bag-like member 92 has leaked out and the bag-like member 92 is in a deflated state, so that damage to the device inside the built-in package 95 can be detected early. You can also. A user or the like of the electronic thermometer 100 estimates the use state (whether it is unused or the period of use) of the electronic thermometer 100 (or the built-in package 95) from the leakage state of air in the bag-like member 92. It is also possible.

  The inside of the bag-like member 92 may be sealed in a substantially vacuum shape. Similar to the above-described case where the bag-like member 92 is filled with gas, a predetermined protrusion is formed by damage to the device (the control board 20, the display unit 30, or the power supply unit 40) inside the built-in package 95. There is a case. Also in this case, the protrusions make a hole in the bag-like member 92 from the inside of the bag-like member 92, and the internal vacuum is broken.

  When the user of the electronic thermometer 100 notices that the vacuum in the bag-like member 92 is broken, it is possible to detect the breakage of the equipment inside the built-in package 95 at an early stage. The user of the electronic thermometer 100 estimates the use state (whether it is unused or the period of use) of the electronic thermometer 100 (or the built-in package 95) from the air intrusion state into the bag-like member 92. It is also possible to do.

[Modification of Embodiment 1]
(First modification)
Referring to FIG. 6, a filling member 16 such as silicon gel may be filled between the periphery of the temperature sensing unit 11 and the bag-like member 92 (tip 92U). The thermal conductivity to the temperature sensing part 11 is improved, and the positional deviation of the temperature sensing part 11 is prevented inside the bag-like member 92 (tip 92U). In this case, the temperature sensing part 11 is in contact with at least a part of the inner surface 92S of the bag-like member 92 via the filling member 16, and the temperature sensing part 11 is in contact via the filling member 16. The outer surface 92T of the bag-like member 92 corresponding to the inner surface 92S may be in contact with the inner peripheral surface 51S of the sheet-like member 51 or the bottom surface portion 52S (inner peripheral surface) of the case body 52.

  According to this configuration, heat transfer from the housing 50 (the sheet-like member 51 or the case body 52) and the bag-like member 92 (the tip 92U) to the temperature-sensing unit 11 is enhanced, and the heat-responsiveness in the temperature-sensing unit 11 is improved. Can be made.

(Second modification)
Referring to FIG. 7, only the periphery of the temperature sensing unit 11 may be sealed in a substantially vacuum shape. In this case, the periphery of the temperature sensing unit 11 is covered with a bag-like member 92 (tip 92U) in an airtight manner. Also in this case, the thermal conductivity to the temperature sensing part 11 is improved.

A predetermined nameplate can be affixed or printed on the surface of the PET layer on the base material layer side. The first sheet-like member 51A and the second sheet-like member 52A can be manufactured by cutting or the like. The first sheet-like member 51A and the second sheet-like member 52A are configured in a substantially U shape in plan view so that the width gradually decreases toward the side on which the thermistor 10 is disposed.

  The first sheet-like member 51A may be configured from a member having transparency.

  When the electronic thermometer 101 is assembled, the built-in package 95 is disposed on the second sheet-like member 52A (see the arrow in FIG. 8). In the present embodiment, the distal end 92U side of the bag-like member 92 including the thermistor 10 is disposed on one end side of the second sheet-like member 52A along the longitudinal direction of the second sheet-like member 52A. The rear end side of the bag-like member 92 including the control board 20, the display unit 30, the power supply unit 40, and the like is disposed on the other end side of the second sheet-like member 52A along the longitudinal direction of the second sheet-like member 52A. The

By this joining, an annular joining region 54 (see FIG. 9) is formed on the outer edges of the first sheet-like member 51A and the second sheet-like member 52A, and the built-in package 95 is sealed in a substantially airtight space 53 (see FIG. 9). 9) is formed.

  In order to join the first sheet-like member 51A and the second sheet-like member 52A to each other, the first sheet-like member 51A and the second sheet-like member 52A are arranged to face each other so that the periphery of the first sheet-like member 51A coincides with the periphery of the second sheet-like member 52A. . In this state, ultrasonic waves are applied to the contact portion (the portion corresponding to the bonding region 54) of the first sheet-like member 51A and the second sheet-like member 52A. Due to the applied ultrasonic waves, the periphery (such as a sealant layer) of the first sheet-like member 51A and the second sheet-like member 52A is temporarily dissolved. By the melting, the peripheral edges of the first sheet-like member 51 </ b> A and the second sheet-like member 52 </ b> A are welded (crimped) in the joining region 54. The peripheral edges of the first sheet-like member 51A and the second sheet-like member 52A may be joined by heat welding or an adhesive.

  In the state where the electronic thermometer 102 is assembled, the opening 50H is closed by ultrasonic welding or the like. Since the surface of the electronic thermometer 102 (housing 50B) is configured to be smooth, the sanitary aspect when the electronic thermometer 102 is cleaned and disinfected using ethanol or the like is further improved.

  The housing 50B configured in a bag shape can also be established as an invention independent of the technical idea that the built-in package 95 is provided in the housing 50B. By adopting the bag-shaped housing 50B in an electronic thermometer, problems such as improvement in hygiene after cleaning and disinfection can be solved.

[Embodiment 3]
FIG. 11 is a perspective view showing an exploded state of the built-in package 95A of the electronic thermometer in the present embodiment. FIG. 12 is a plan view showing the assembled state of the built-in package 95A.

  In the electronic thermometer in the present embodiment, the bag-like member 92A of the built-in package 95A has a first sheet-like member 97 and a second sheet-like member 98 that are formed in the same shape. The first sheet-like member 97 and the second sheet-like member 98 are, for example, a base material layer made of paper or a polyethylene film, a sealant layer disposed on the lower surface side of the base material layer, and an upper surface side of the base material layer. Each is configured by laminating an arranged PET layer (Polyethylene Terephthalate layer).

  The thickness of the first sheet-like member 97 and the second sheet-like member 98 is, for example, 0.1 mm to 0.3 mm, respectively. A predetermined nameplate can be affixed or printed on the surface of the PET layer on the base material layer side. The first sheet-like member 97 and the second sheet-like member 98 can be manufactured by cutting or the like. The first sheet-like member 97 and the second sheet-like member 98 are configured in a substantially U shape in plan view so that the width gradually decreases toward the side where the thermistor 10 is disposed.

  The 1st sheet-like member 97 is good to be comprised from the member which has transparency. When the first sheet-like member 97 is not composed of a member having transparency, a part of the first sheet-like member 97 is a protective member having transparency so that the display panel 31 of the display unit 30 can be visually recognized from the outside. Should be provided.

  When the built-in package 95A is assembled, the thermistor 10, the control substrate 20, the display unit 30, the power supply unit 40, and the substrate 29 are arranged on the second sheet-like member 52A (see the arrow in FIG. 11). In this state, the peripheral edge of the first sheet-like member 97 and the peripheral edge of the second sheet-like member 98 are joined to each other. By the joining, a bag-like member 92A is formed by joining the first sheet-like member 97 and the second sheet-like member 98 to each other. An annular joining region 99 (see FIG. 12) is formed on the outer edges of the first sheet-like member 97 and the second sheet-like member 98, and a space 93 (see FIG. 12) in which the inside is sealed in a substantially airtight manner is formed. The

  In order to join the first sheet-like member 97 and the second sheet-like member 98 to each other, the first sheet-like member 97 and the second sheet-like member 98 are arranged to face each other so that the periphery of the first sheet-like member 97 and the periphery of the second sheet-like member 98 coincide. . In this state, ultrasonic waves are applied to the contact portion (the portion corresponding to the joining region 99) of the first sheet-like member 97 and the second sheet-like member 98. Due to the applied ultrasonic waves, the periphery (such as a sealant layer) of the first sheet-like member 97 and the second sheet-like member 98 is temporarily dissolved. By the melting, the peripheral edges of the first sheet-like member 97 and the second sheet-like member 98 are welded (bonded) in the joining region 99.

  By using the built-in package 95A thus obtained in the same manner as the electronic thermometer in the above-described first and second embodiments, the same operation and effect as in the first and second embodiments can be obtained. It becomes possible.

  As mentioned above, although each embodiment based on this invention was described, each embodiment disclosed this time is an illustration and restrictive at no points. The technical scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
