Description

【Technical Field】 【0001】 The present invention relates to a portable diagnostic device used in the dental or veterinary field (dentistry). 【Background Art】 【0002】 Conventionally, in order to perform home visits for dental treatment of people undergoing home care, dentists, dental hygienists, assistants, and veterinarians (hereinafter referred to as dentists, etc.) carry a dedicated portable diagnostic device that houses dental diagnostic instruments or driving equipment such as compressors. For example, there is a home visit dental diagnostic device that stores diagnostic instruments and the like in a portable housing (see Patent Document 1). In such a device, an opening / closing lid is provided at the opening of the housing. The lid is provided with a holder (hereinafter also referred to as a hanger) for detachably supporting the diagnostic instrument. During diagnosis and treatment, a diagnostic instrument with a hose connected to the base is attached to the holder on the upper side of the opened lid, making it easier for the dentist performing the treatment to use the diagnostic instrument. 【0003】 Also, a portable dental unit with a detachable holder is known (see Patent Document 2). In such a device, a lid member is erected from one side of the opened case opening, and a holder is attached to the upper side of the lid member. After the treatment is completed, the diagnostic instrument is removed from the holder, and then the holder is removed from the upper side of the lid member and stored in the case. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 JP 2013 - 233334 【Patent Document 2】 JP 2021 - 83749 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 However, with conventional mobile dental treatment devices, when finishing treatment and packing up, it was not possible to close the lid with the dental instruments still attached to their holders. The instruments had to be moved to another holder inside the housing, and the hoses had to be bundled together and stored in a way that they would not interfere with opening and closing the device. 【0006】 Furthermore, with portable dental units, it is not possible to close the lid and store the unit with the dental instruments attached to the holders. Therefore, at the end of a medical examination, the medical instruments must be removed from their holders and stored in the case, and then the holders must be separated from the lid and stored as well. Furthermore, at the start of treatment, it is necessary to attach the holder to the top of the lid component and then support the medical instrument in the holder to set it up. Furthermore, in both cases, the casing and lid occupy a certain amount of space in the treatment area, making it difficult to bring the holder close to the dentist or patient. Therefore, the instruments are difficult to use because they are far from the dentist during treatment, and further improvements are needed. 【0007】 The present invention aims to provide a portable medical device that can be set up and taken down easily and quickly, while improving convenience during treatment. [Means for solving the problem] 【0008】 The portable medical device of the present invention comprises a housing having a concave storage compartment with an open top, a medical instrument stored in the storage compartment, and a holder for detachably holding the medical instrument. The portable medical device also comprises an arm whose tip is connected to the holder and whose base is rotatably connected to the housing via an arm rotation axis, and a hose whose tip is connected to the medical instrument and whose base is connected to the housing. With the hose connected to the medical instrument held in the holder and the housing, the arm rotates toward the storage compartment to store the arm, holder, and medical instrument in the storage compartment, and rotates toward the opposite side of the storage compartment to position the holder and medical instrument above the housing. The housing is equipped with a power source located in the center. The storage section comprises an arm storage section for storing the arm, an instrument storage section for storing the holder and medical instruments, and a hose storage section for storing the hose. The arm storage section, instrument storage section, and hose storage section are arranged to surround the power source from three sides.It is characterized by the following. [Effects of the Invention] 【0009】 According to the present invention, a portable medical device is provided that improves convenience during treatment while being easy and quick to set up and take down.

[Figure 6] This is a cross-sectional view taken along the line VI-VI in Figure 5, schematically illustrating the hoses stored inside the housing when the arm is in the retracted position of a portable medical device. [Modes for carrying out the invention] 【0011】 Hereinafter, a portable medical device 1 according to an embodiment of the present invention will be described with reference to the drawings as appropriate. 【0012】 As shown in Figure 1, the portable medical device 1 of Embodiment 1 comprises a housing 3 having a concave storage compartment 100 with an open top, and a plurality of medical instruments 4 to 7 that are stored in the storage compartment 100. Furthermore, the portable medical device 1 includes an arm 20, a plurality of hoses 30, a lid 9 (see Figure 3) that opens and closes the upper opening of the storage section 100, and a holder 10 that detachably holds the medical instruments 4 to 7. 【0013】 Among these, the housing 3 has a substantially rectangular shape when viewed from above and exhibits a rectangular parallelepiped box shape having a predetermined height in the vertical direction. At the opening edge 102 of the upper part of the housing 3, a first side 103 provided on a relatively short short side and a second side 104 provided on a long side that is orthogonal to the first side 103 and longer than the first side 103 are formed. Further, on the opposite side of the first side 103, a third side 105 is formed in parallel with the first side 103. Also, on the opposite side of the second side 104, a fourth side 106 is formed in parallel with the second side 104. And the upper opening of the storage part 100 is surrounded by the four sides of the first side 103, the second side 104, the third side 105, and the fourth side 106. 【0014】 The housing 3 of the portable medical device 1 that needs to be carried around for home visits or the like is preferably of a size and weight that can be transported. Also, the housing 3 of the embodiment is provided with a handle 18 or a shoulder strap or the like. The handle 18 is used when a transporter such as a dentist or an assistant transports it. 【0015】 Also, as shown in FIG. 3, a concave storage part 100 is provided inside the housing 3. The storage part 100 includes an arm storage part 107 for storing the arm 20, an instrument storage part 108 for storing the holder 10 at the tip of the arm 20 and the medical instruments 4 to 7, and a hose storage part 109 for storing the hose 30. 【0016】 Also, the housing 3 is provided with an arm 20 for detachably holding the medical instruments 4 to 7. The arm 20 is composed of a rod-shaped body having a predetermined length. The base end portion 22 of the arm 20 is rotatably connected within a predetermined movable range via an arm rotation shaft 23. Also, the arm rotation shaft 23 is provided so as to be at the height of the opening edge 102 (see FIG. 4) located at the upper part inside the housing 3. And a holder 10 is rotatably connected to the tip portion 21 of the arm 20. 【0017】 In Figure 1, medical instruments 4-7 each have handpieces 8a, 8b, etc. (see Figure 1) that require sterilization for each patient, and connecting parts that are detachably held in the holder 10 and connect each handpiece 8a, etc. Normally, each handpiece 8a, etc., is not stored in the portable medical device while connected during visits or when packing up. Instead, a sterilized handpiece 8a, etc., is stored in an individual storage device (such as a bag) for each patient at the visiting location and transported, and connected during treatment as a measure to prevent infection. Therefore, the medical instruments 4 to 7 used in the description in the embodiments are medical instruments of the present invention even when the detachable handpiece 8a is removed for sterilization (even if only the connecting part is present). 【0018】 Furthermore, the arm 20 of the embodiment has a range of motion that extends upward from position a (approximately -10 degrees below horizontal position HL) where it is stored in the arm storage section 107. In the arm 20 of the embodiment, the range of motion α1 is set to be within the range of approximately -10 degrees to approximately 190 degrees (see position c), and preferably, the range of motion α2 is set to be within the range of approximately -10 degrees to approximately 120 degrees. As a result, at position b, where the arm 20 is rotated to its outermost position, the upper part of the arm 20 protrudes beyond the first side edge 103 formed outside the arm rotation axis 23 within the opening periphery 102. Therefore, the arm 20 can be easily set to approach the optimal hand position for treatment by a dentist or other professional at position b, where the holder 10 at its tip stops rotating. 【0019】 The holder 10 has a cylindrical shape and is cantilevered to the tip 21 of the arm 20, with the holder rotation axis 24 as the center of rotation. The holder 10 is provided with a plurality of holding portions 14 to 17. In this embodiment, the holding portions 14 to 17 are provided at four equal intervals along the longitudinal direction of the holder 10. As shown in Figure 5, the holding portions 14 to 17 in this embodiment have the same pitch P2 as the pitch P1 of the plurality of hose connection portions 33 provided on the housing 3. The retaining parts 14 to 17 are partially cut out in the shape of vertical grooves, and each has a retaining recess that has a roughly C-shaped horizontal cross-section. A hose 30 is inserted through each vertical groove, and each of the medical instruments 4 to 7 is detachably held in each retaining recess. Furthermore, the holder 10 is not limited to a cylindrical shape; it may also be prismatic, or any block shape with multiple holding parts. 【0020】 These holding parts 14 to 17 are aligned in a direction perpendicular to the direction of the holder rotation axis 24 of the holder 10, and hold the respective medical instruments 4 to 7. Furthermore, the holding parts 14 to 17 are configured to rotate the holder 10 around the holder rotation axis 24, thereby causing the tips of the medical instruments 4 to 7 to protrude upward and the base end to which the hose 30 is connected to be pointed downward (see Figure 1). 【0021】 As shown in Figure 2, the holder 10 is pivotally supported by a holder rotation axis 24 located at the tip 21 of the arm 20 and positioned parallel to the arm rotation axis 23. When the arm 20 is rotated upwards above the housing 3 and then raised to an upright position, the longitudinal dimensions of the arm 20 are set such that the position of the holder 10 rises to a height near the dentist's hand. 【0022】 The arm rotation axis 23 or holder rotation axis 24 of the embodiment has a torque hinge structure 200, 201 that holds at any angle as long as a force exceeding a predetermined amount is not applied. This configuration allows the medical instruments 4-7 to be held in the desired position during treatment and stopped at any angle for setting, and when dismantling, the arm 20 and holder 10 can be rotated by applying a predetermined force, making them easy to move. 【0023】 Furthermore, the arm rotation axis 23 or the holder rotation axis 24 has a locking mechanism 300, 301 (see Figure 1) that can be locked at a desired angle. The locking mechanisms 300 and 301 allow the arm 20 or holder 10 to be stopped at a desired angle by operating the lever member to perform a locking operation. Furthermore, the locking mechanisms 300 and 301 can be released by operating the lever members, allowing the arm rotation axis 23 or the holder rotation axis 24 to rotate freely around their respective axes. This makes it possible to rotate the arm 20 or the holder 10 to a desired angle. 【0024】 As described above, in this embodiment, the arm rotation axis 23 is provided with a torque hinge structure 200 and a locking mechanism 300, while the holder rotation axis 24 is provided with a torque hinge structure 201 and a locking mechanism 301. Therefore, the arm rotation axis 23 and the holder rotation axis 24 can be held at any angle as long as a force exceeding a predetermined level is not applied. Furthermore, they can be locked to prevent rotation by the locking mechanisms 300 and 301 as needed. For example, the tips of the medical instruments 4-7 can be made to protrude upward, while the base end to which the hose 30 is connected can be fixed facing downward. 【0025】 Furthermore, the hose 30 has its tip 31 connected to the medical instruments 4-7, respectively, and its base 32 connected to the housing 3. In this embodiment, each of the base ends 32 of the multiple hoses 30 is provided with a hose connection portion 33 connected to the housing 3. The hose connection portion 33 is located on the upper surface of the housing 3. The hose connection portion 33 is aligned parallel to the arm rotation axis 23 and is located near the outer position of the arm rotation axis 23 when viewed from above (see Figure 5). 【0026】 Furthermore, a drive source 400 is located in the center of the housing 3 shown in Figure 5. The drive source 400 includes a compressor and power control device for driving medical instruments 4, and a vacuum pump as needed. The arm storage section 107, instrument storage section 108, and hose storage section 109 are provided to surround the drive source 400 from three sides. 【0027】 Furthermore, the arm 20 is configured to rotate toward the storage section 100 while the hose 30 is connected to the medical instruments 4-7 held in the holder 10 and the housing 3, thereby storing the arm 20, holder 10, and medical instruments 4-7 in the arm storage section 107 and instrument storage section 108, respectively, and storing the hose 30 in the hose storage section 109. 【0028】 The arm 20 can then rotate to the opposite side of the storage section 100 to remove the holder 10 and the medical instruments 4-7 from the upper opening of the housing 3 and position them above the housing 3. Furthermore, as shown in Figure 1, as the arm 20 rotates toward the opposite side of the storage section 100, it rotates further from above the housing 3 (see Figure 2) to the outside of the first side edge 103. If the arm 20 rotates further in conjunction with this rotation, the holder 10 and the medical instruments 4-7 are positioned diagonally above and to the outside of the arm rotation axis 23. 【0029】 In this embodiment, the first side 103 is formed on the outside near the arm rotation axis 23, parallel to the arm rotation axis 23. The second side 104 is provided in a direction perpendicular to the first side 103. The second side 104 is recessed in a direction that causes the arm 20 to tilt inward into the housing 3 with the arm rotation axis 23 as the center of rotation. Then, as shown in Figure 3, the arm 20 is housed in the arm storage section 107 of the storage section 100 with its longitudinal direction aligned along the second side edge 104. 【0030】 Furthermore, a third side 105 is formed on the opposite side of the first side 103, parallel to the first side 103. Also, a fourth side 106 is formed on the opposite side of the second side 104, parallel to the second side 104. As shown in Figure 6, an instrument storage section 108 for storing the holder 10 and medical instruments 4-7 is recessed on the inside of the third side 105, extending to near the bottom surface 13. In the portable medical device 1 of this embodiment, the arm 20 is rotated toward the storage section 100 to store the holder 10 and medical instruments 4-7 in the instrument storage section 108. At this time, the holder 10 connected to the tip 21 of the arm 20 is rotated around the holder rotation axis 24 as the center of rotation. 【0031】 The arm 20 of this embodiment is configured so that the holder rotation axis 24 can be positioned below the arm rotation axis 23 by a distance h1 in the vertical direction. As a result, even if the tips of the medical instruments 4-7 protrude upward from the holder 10, they will fit inside the storage section 100 and will not interfere with the lid 9. 【0032】 The total length L1 (omitted in the figure) of each hose 30 in this embodiment is set to be longer than the straight-line distance L2 between the hose connection part 33 and the holder 10 when the holder 10 is positioned above the housing 3, as shown in Figure 2. Note that the total length of each hose 30 does not need to be the same for all hoses 30. 【0033】 Furthermore, the total length L1 of each hose in this embodiment is set to be at least twice the vertical dimension h3 from the hose connection part 33 to the bottom surface 13 of the housing 3, as shown in Figure 4. Furthermore, the housing 3 of this embodiment is configured such that the vertical dimension h3 from the bottom surface 13 to the hose connection part 33 is added to the total length dimension of the hose 30, thereby expanding the space in which medical instruments 4 to 7 can be used to the upper part of the housing 3. 【0034】 Furthermore, as shown in Figure 3, the portable medical device 1 has a lid 9 detachably attached to the top of the housing 3. The lid 9 has the same dimensions as the opening periphery 102 of the top opening of the housing 3. Furthermore, as shown in Figure 6, a recessed space with a predetermined vertical dimension is formed on the inside of the lid 9, continuous with the upper part of the storage section 100. This prevents the upwardly protruding arm rotation shaft 23 from interfering with the inside of the lid 9 when the lid 9 is closed. Furthermore, the depth of the concave shape of the lid 9 may be set so that the tips of the medical instruments 4 to 7 stored in the storage section 100 do not interfere with the inside of the lid 9 when it is attached. This allows the lid 9 to be attached to the housing 3 even if the upper parts of the stored medical instruments 4 to 7 protrude slightly upward from the upper opening of the housing 3. 【0035】 Next, the effects and advantages of the portable medical device 1 of the embodiment will be explained in the order of installation, setting up, and dismantling at the treatment site. In the portable medical device 1 of this embodiment, the housing 3 is transported to and installed at the medical treatment location where the patient is treated. Then, the lid 9 shown in Figure 3 is removed to open the top of the storage compartment 100. 【0036】 Next, setting is performed in preparation for treatment. In setting, first, as shown in Figure 2, the arm 20 is rotated to the opposite side from the storage unit 100. As a result, the arm 20 is pulled upward while rotating around the arm rotation axis 23 as the center of rotation. The holder 10, which is located at the tip of the arm 20, is removed from the instrument storage unit 108 while still holding the medical instruments 4-7. 【0037】 As the arm 20 rotates, the operator applies a force exceeding a predetermined limit to the torque hinge structure 200 shown in Figure 1. This allows rotation around the arm rotation axis 23, enabling the arm 20 to rotate to the desired position. 【0038】 For example, as shown in Figure 2, the arm 20 can be rotated to the opposite side of the storage section 100, allowing the holder 10 and the medical instruments 4-7 to be positioned above the housing 3 and stopped directly above the arm rotation axis 23. In other words, if a force exceeding a predetermined value is applied in the direction that rotates the arm 20, the torque hinge structure 200 will not be able to maintain the stopped state of the arm 20 beyond a preset tolerance value. This allows the holder 10 to be rotated around the holder rotation axis 24. Similarly, the torque hinge structure 201 allows the medical instrument 4 held in the holder 10 to be set at an upward angle, protruding upward from the holder 10 by a predetermined distance. 【0039】 The torque hinge structures 200 and 201 can hold the arm 20 and holder 10 so that they do not move at any angle unless a force exceeding a predetermined level is applied. Therefore, the holder 10 can be stopped at a desired position while holding the medical instruments 4 to 7. This allows the dental instruments 4-7 held in the holder 10 to be positioned closer to the dentist's hand level, making them easier to use. 【0040】 Furthermore, as shown in Figure 1, the holder 10 and the dental instruments 4-7 can be moved further outward from above the housing 3 by rotating the arm 20. This allows the dental instruments 4-7 held in the holder 10 to be brought closer to the dentist's hand level, making them easier to use, without the housing 3 obstructing the treatment space. In this case, the rotational angle positions of the arm 20 and holder 10 can be fixed using the locking mechanisms 300 and 301 shown in Figure 1. This prevents the arm 20 or holder 10 from rotating due to the weight of the medical instruments 4-7 or unintended collisions. 【0041】 Furthermore, once the treatment is complete, the portable medical device 1 is dismantled by storing the medical instruments 4-7 used in the treatment inside the housing 3. During the dismantling process, the arm 20 is rotated toward the storage section 100, and the arm 20, holder 10, and medical instruments 4-7 are stored in the storage section 100. Then, the top of the housing 3 can be closed with the lid 9 without the tips of the medical instruments 4-7 interfering with each other. 【0042】 In this way, the portable medical device 1 rotates the arm 20 around the arm rotation axis 23 in a single action while the medical instruments 4 to 7 are held in the holder 10. As a result, the medical instruments 4, etc., can be positioned as desired, and the medical instruments 4 to 7 can be stored in the housing 3 while still being held in the holder 10. Thus, a portable medical device 1 is provided that can be set up and taken down easily and quickly. 【0043】 Furthermore, as shown in Figure 5, even if the arm 20 is made to a length that can be stored in the arm storage section 107 of the housing 3, the vertical dimension h3 from the hose connection section 33 to the bottom surface 13 of the housing 3, as shown in Figure 4, is added to the length of the arm 20. Therefore, the dental instruments 4 to 7 can be easily set up at approximately the height of the dentist's hand. 【0044】 Furthermore, as shown in Figure 5, the hose connection portion 33 is aligned outward and parallel to the arm rotation axis 23 of the housing 3. Also, the total length L1 of the hose 30 may be set to be at least twice the vertical dimension h3 from the bottom surface 13 of the housing 3 to the hose connection portion 33, as shown in Figure 4. This allows dentists to improve convenience when performing treatments using dental instruments 4-7, thus providing practically beneficial effects. 【0045】 As described above, the portable medical device 1 of the present invention, as shown in Figure 1, comprises a housing 3 having a concave storage section 100 with an open top, and medical instruments 4 to 7 stored in the storage section 100. The portable medical device 1 also comprises a holder 10 for detachably holding the medical instruments 4 to 7. Furthermore, the portable medical device 1 comprises an arm 20 whose tip 21 is connected to the holder 10 and whose base 22 is rotatably connected to the housing 3 via an arm rotation axis 23, and a hose 30 whose tip 31 is connected to the medical instruments 4 to 7 and whose base 32 is connected to the housing 3. 【0046】 As shown in Figure 3, with the hose connected to the medical instrument held in the housing and holder, the arm 20 rotates toward the storage section 100 to store the arm 20, holder 10, and medical instruments 4-7 in the storage section 100. As shown in Figure 2, it also rotates toward the opposite side of the storage section 100 to position the holder 10 and medical instruments 4-7 above the housing 3. 【0047】 The present invention, configured in this manner, can provide a portable medical device 1 that improves convenience during treatment while being easy and quick to set up and take down. In other words, during treatment, as shown in Figure 2, the arm 20 can be rotated to the opposite side of the storage unit 100, allowing the holder 10 and the dental instruments 4-7 held in the holder 10 to be positioned above the housing 3. This brings the dental instruments 4-7 closer to the dentist's hand level for easy setup, improving convenience during treatment. Furthermore, when treatment is complete, as shown in Figure 3, the arm 20 can be rotated toward the storage unit 100, allowing the arm 20, holder 10, and the medical instruments 4-7 held by the holder 10 to be stored in the storage unit 100. Therefore, the portable medical device 1 can be easily dismantled. 【0048】 In this way, the portable medical device 1 allows for easy and quick setup at the start of treatment and removal at the end of treatment by holding the medical instruments 4 to 7 in the holder 10 and rotating the arm 20 around the arm rotation axis 23 in a single action. 【0049】 Furthermore, as shown in Figure 1, when the arm 20 is rotated to the opposite side of the storage section 100, the holder 10 and the medical instruments 4-7 can be moved and positioned outside the opening periphery 102 of the storage section 100 (see Figure 4). 【0050】 Therefore, even if the housing 3 occupies a certain amount of space in the treatment area, the rotation of the arm 20 allows the treatment instruments 4-7 to be set up in a position away from the housing 3, thus preventing them from interfering with treatment. For example, instruments 4-7 can be positioned to be more easily used, such as by bringing them closer to the dentist's hands. 【0051】 As shown in Figure 5, the opening periphery 102 has a first side 103 formed outside the arm rotation axis 23, and a second side 104 formed in a direction perpendicular to the first side 103 and longer than the first side 103. The arm 20 is housed in the storage section 100 with its longitudinal direction aligned with the second side 104. Therefore, the overall length of the arm 20 can be set to be greater than when it is stored along the first side 103. Thus, in the setting shown in Figure 2, where the arm 20 is rotated to the opposite side of the storage section 100, the medical instruments 4 to 7 held in the holder 10 can be positioned further above the housing 3. 【0052】 In this embodiment, as shown in Figure 4, the arm rotation axis 23 is positioned at the height of the opening periphery 102 located at the upper part of the housing 3. Therefore, the holder 10 can move over an even wider range by adding the vertical dimension h3 from the hose connection part 33 to the bottom part 13 to the length of the arm 20. Furthermore, the hose connection portion 33 is located near the arm rotation axis 23 and outside the arm rotation axis 23, between it and the first side 103. Therefore, the hose 30, which is removed from the storage compartment 100 and hangs down outside the opening perimeter 102, is less likely to interfere with the arm 20. Therefore, the placement of the medical instruments 4-7 can be changed to be positioned above and outside the housing 3 according to the treatment space, thereby improving ease of use. 【0053】 Furthermore, as shown in Figure 5, the holder 10 is rotatably supported on a holder rotation shaft 24, which is provided at the tip 21 of the arm 20 and is arranged parallel to the arm rotation shaft 23. Therefore, the twisting of the hose 30 is reduced, allowing it to be smoothly inserted into and removed from the storage compartment 100. 【0054】 Furthermore, as shown in Figure 6, with the arm 20 rotated toward the storage section 100, the holder rotation axis 24 is positioned below the arm rotation axis 23. As a result, even if the medical instruments 4-7 held in the holder 10 protrude upward from the holder 10, the holder 10 can be moved below the arm rotation axis 23, allowing the upper ends of each medical instrument 4-7 to be housed within the instrument storage section 108. Therefore, the medical instruments 4 to 7 can be easily stored in the storage section 100 while still being held in the holder 10. 【0055】 As shown in Figure 5, a hose connection section 33 is provided where the base ends 32 of multiple hoses 30 are each connected to the housing 3, and the hose connection sections 33 are aligned parallel to the arm rotation axis 23. This ensures that even when multiple medical instruments 4-7 are held in the holder 10, spacing is maintained between it and other adjacent hoses 30. Therefore, the risk of the hoses 30 becoming entangled is reduced. 【0056】 Furthermore, at least one of the arm rotation axis 23 or the holder rotation axis 24 has a torque hinge structure 200, 201 that holds it at any angle as long as a force exceeding a predetermined level is not applied. As a result, during treatment, a force greater than a predetermined amount is applied in the direction opposite to the storage unit 100 to extend the arm 20 from the storage unit 100 and rotate it. Once the arm has rotated to the desired angle, it will stop with the medical instruments 4-7 held in the holder 10 at its tip, unless force is applied. Therefore, dentists can position the dental instruments 4-7 in a convenient and desired location, such as within easy reach of their hands. Furthermore, when withdrawing the device, applying a force exceeding a predetermined level causes the arm 20 and holder 10 to rotate and move easily. Therefore, the dentist can rotate the arm 20 around the arm rotation axis 23 in a single action, release their hand at the desired position, and stop it there, thus improving convenience. 【0057】 Furthermore, at least one of the arm rotation axis 23 or the holder rotation axis 24 has a locking mechanism 300, 301 that can be locked at a desired angle. As a result, the arm 20 or holder 10 can be locked in place by operating the locking mechanisms 300 and 301 at a convenient angle, preventing rotation. Therefore, the dentist can further stabilize and fix the holder 10 in the desired position by using the locking mechanisms 300 and 301. For example, the holder 10 or arm 20 can be prevented from moving even if the dentist or assistant attaches or detaches the dental instruments 4-7 held in the holder 10, or accidentally touches them. 【0058】 Furthermore, as shown in Figure 5, the portable medical device 1 is equipped with a drive source 400 located in the center of the housing 3. The storage section 100 includes an arm storage section 107 for storing the arm 20, an instrument storage section 108 for storing the holder 10 and medical instruments 4-7, and a hose storage section 109 for storing the hose 30. The arm storage section 107, the instrument storage section 108, and the hose storage section 109 are arranged to surround the drive source 400 from three sides. 【0059】 As a result, the heavy drive source 400 is positioned in the center of the chassis 3, and the chassis is evenly balanced without any bias. Therefore, for example, transporters such as dentists and assistants can reduce their burden when transporting the device using the handle 18 or shoulder strap provided on the housing 3. 【0060】 Furthermore, the arm storage section 107, the equipment storage section 108, and the hose storage section 109, which surround the drive source 400 from three sides, can be made larger in size to conform to the inside of the opening periphery 102 of the housing 3. Therefore, the arm storage section 107, the instrument storage section 108, and the hose storage section 109 can each accommodate the arm 20, the holder 10, and the hose 30, which are set to have relatively long overall lengths. Consequently, the range of use for medical instruments 4-7 can be further expanded. 【0061】 Furthermore, as shown in Figure 1, the holder 10 has holding parts 14 to 17 that hold the medical instruments 4 to 7 at the same pitch P2 as the pitch P1 of the multiple hose connection parts 33. The total length of the hose 30 is set to be longer than the straight-line distance L2 between the hose connection part 33 and the holder 10, with the holder 10 positioned above the housing 3. 【0062】 As shown in Figure 5, the pitch P2 of the holding parts 14-17 of the holder 10 is the same pitch P1 as the hose connection part 33 of the housing 3. Therefore, as shown in Figure 2, the length of each hose 30 can be made equal for even greater ease of use. 【0063】 Furthermore, the total length of the hose 30 can be set to be longer than the straight-line distance L2 between the medical instruments 4-7 held in the holder 10 and the hose connection part 33. For example, as shown in Figure 1, the set hose 30 can be dropped from the hose connection part 33 to the outside of the opening periphery 102 and left to sag on the floor. Therefore, when using medical instruments 4 to 7, the hose 30 can be extended without interfering with the arm 20 or housing 3, and the length of the hose can be used effectively. 【0064】 As shown in Figure 4, the total length of the hose 30 is set to be more than twice the dimension h3 from the hose connection part 33 to the bottom surface part 13 of the housing 3. This allows the portable medical device 1 to have a longer overall length for the hose 30. For example, in this embodiment, as shown in Figure 3, the hose 30 is bent and folded and stored in the hose storage section 109. As shown in Figure 5, the hose storage section 109 is located inside the fourth side 106 of the housing 3 and is recessed to the vicinity of the bottom surface 13, as shown in Figure 6. Therefore, even a long hose 30 can be folded and coiled vertically and stored compactly inside the hose storage compartment 109. During medical treatment, the hose 30 extends from the hose connection part 33, which is located on the top surface of the housing 3 at a high position, without coming into contact with other parts. In this way, the hose 30, which is set to be relatively long, can be used effectively to expand the range in which the medical instruments 4-7 can be moved. Therefore, practical benefits such as improved operability of medical instruments 4-7 and enhanced convenience during treatment are achieved. 【0065】 The present invention is not limited to the embodiments described above, and various modifications are possible. The embodiments described above are illustrative examples provided to facilitate understanding of the present invention, and are not necessarily limited to those comprising all the configurations described.

In addition, it is possible to delete parts of the configuration of each embodiment, or to add or replace other configurations. Possible modifications to the above embodiments are as follows, for example. 【0066】 In this embodiment, the holder 10 is provided at the tip 31 of the arm 20 and rotatably supported on a holder rotation axis 24 that is arranged parallel to the arm rotation axis 23. However, the present invention is not limited thereto. For example, the holder 10 may be configured to rotate around a vertical axis provided at the tip 31 of the arm 20, that is, the holder 10 may be configured to pivot horizontally to the floor with the vertical axis as the center of rotation. In other words, the shape of the arm 20 and the holder 10, the number of holding parts 14, and other components, and the materials may be any. 【0067】 Furthermore, in this embodiment, the arm rotation axis 23 or the holder rotation axis 24 is provided with torque hinge structures 200, 201 and locking mechanisms 300, 301, respectively, but it is not limited to this. For example, either the torque hinge structures 200, 201 or the locking mechanisms 300, 301 may be provided. Furthermore, the components may be combined in any way, for example, by providing a torque hinge structure 200 on the arm rotation axis 23 and only a locking mechanism 301 on the holder rotation axis 24. In other words, the shape, structure, number, and combination of the torque hinge structures 200, 201 and the locking mechanisms 300, 301 may be configured in any way.
