[Figure 7] FIG. 2 is a cross-sectional view showing a YZ cross section of the clamping portion. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of a medical display device according to an embodiment of the present invention. FIG. 1 depicts an X-axis, a Y-axis, and a Z-axis. In FIG. 1, the direction from the lower left to the upper right is referred to as the X-direction, left-right direction, or both-side direction, the upper right direction is referred to as the "+X-direction" or right side, and the lower left direction is referred to as the "-X-direction" or left side. In FIG. 1, the up-down direction is referred to as the Y-direction or up-down direction, the upper direction is referred to as the "+Y-direction" or upper side, and the lower direction is referred to as the "-Y-direction" or lower side. In FIG. 1, the direction from the lower right to the upper left is referred to as the Z-direction or depth direction, the lower right direction is referred to as the "+Z-direction" or front side, and the upper left direction is referred to as the "-Z-direction" or back side.

[0012] The medical display device 1 shown in FIG. 1 is, for example, a biological information monitor (also called a bedside monitor) that measures and displays biological information such as a patient's heart rate and blood pressure in a hospital room or operating room. The medical display device 1 includes a main body 10. The main body 10 has a display 11, an external input terminal group 12, and an operation switch 13. The main body 10 has a housing 20. The housing 20 houses a control module, a circuit board for a measurement module, and a battery. The display 11 is, for example, a touch panel type liquid crystal display panel that displays biological information. The external input terminal group 12 has various connectors for connecting a measurement unit such as a cuff. The operation switch 13 is, for example, a power standby switch (auxiliary power switch).

[0013] The housing 20 is made of a thermoplastic resin, such as a mixture of PC resin (polycarbonate resin) and ABS resin (acrylonitrile, butadiene, styrene copolymer synthetic resin). The housing 20 comprises a main body case 21 and a front panel 22. The main body case 21 houses the circuit board and battery. The front panel 22 is disposed on the front side (+Z direction) of the main body case 21. The display unit 11 is attached to the front side of the front panel 22. An operation switch 13 is attached to a lower edge 23D (described later) of the front panel 22.

[0014] Fig. 2 is a front view of the front panel of the medical display device. As shown in Fig. 2, the front panel 22 has a rectangular peripheral edge 23. The peripheral edge 23 is composed of a left edge 23A, a right edge 23B, an upper edge 23C, and a lower edge 23D, which are located on the right (+X direction), left (-X direction), upper (+Y direction), and lower (-Y direction) sides of the rectangular center, respectively.

[0015] The front panel 22 has a continuous groove 30 with a U-shaped cross section. In this embodiment, the continuous groove 30 has a groove bottom along the entire length of the groove, but the present invention is not limited to this. For example, the continuous groove 30 may not have a groove bottom along the entire length of the groove, or may not have a groove bottom only in a portion of the length of the groove. The continuous groove 30 is arranged along the rectangular peripheral edge 23. Specifically, the continuous groove 30 has a left groove portion 30A extending linearly along the left edge 23A, a right groove portion 30B extending linearly along the right edge 23B, and an upper groove portion 30C extending linearly along the upper edge 23C.

[0016] The continuous groove 30 further includes a curved groove portion 30D that extends in a curved manner to connect the upper end of the left groove portion 30A to the left end of the upper groove portion 30C, a curved groove portion 30E that extends in a curved manner from the lower end of the left groove portion 30A toward the lower edge 23D, a curved groove portion 30F that extends in a curved manner to connect the upper end of the right groove portion 30B to the right end of the upper groove portion 30C, and a curved groove portion 30G that extends in a curved manner from the lower end of the right groove portion 30B toward the lower edge 23D. In other words, the continuous groove 30 is a clockwise continuation of the curved groove portion 30E, the left groove portion 30A, the curved groove portion 30D, the upper groove portion 30C, the curved groove portion 30F, the right groove portion 30B, and the curved groove portion 30G. A tubular member 40 serving as a sealing member is fitted along the continuous groove 30 .

[0017] The tubular member 40 is an elastic body having a constant cross-sectional shape. A silicone tube having an outer diameter of 1.5 mm and an inner diameter of 0.7 mm is used for the tubular member 40. The length of the tubular member 40 corresponds to the entire length of the continuous groove 30.

[0018] Fig. 3 is a front view of the front panel with the tubular members removed from the continuous grooves. As shown in Fig. 3, clamping portions 31 are arranged at predetermined intervals in the groove length direction in each of the left groove portion 30A, right groove portion 30B, and upper groove portion 30C. Fig. 3 shows the positions at which the clamping portions 31 are arranged.

[0019] Fig. 4 is a partially enlarged view showing curved groove portion 30D. As shown in Fig. 4, clamping portions 31 are arranged at both ends in the groove length direction of curved groove portion 30D. Similarly, clamping portions 31 are arranged at both ends in the groove length direction of each of curved groove portions 30E, 30F, and 30G shown in Fig. 3.

[0020] As described above, continuous groove 30 has clamping portion 31 and non-clamping portion 32, which is a general portion other than clamping portion 31. The groove depth direction of continuous groove 30 is the back side (-Z direction).

[0021] FIG. 5 is an enlarged view showing the clamping portion. FIG. 6 is a cross-sectional view showing the YZ cross section of the non-clamping portion. As shown in FIGS. 5 and 6, the groove depth of the non-clamping portion 32 is 0.9 mm. The groove width of the non-clamping portion 32 is 1.6 mm. This provides a minute gap 33 (play) of 0.1 mm (=1.6-1.5) between the groove wall of the non-clamping portion 32 and the outer periphery of the tubular member 40. The gap 33 is shown in FIG. 6 as gap S1 and gap S2.

[0022] FIG. 7 is a cross-sectional view showing the YZ cross section of the clamping portion. As shown in FIGS. 5 and 7, the groove width of the clamping portion 31 is 1.4 mm. As a result, the groove width of the clamping portion 31 is narrower than the outer diameter of the tubular member 40 by 0.1 mm (=1.5-1.4). Furthermore, the groove depth of the clamping portion 31 is 0.9 mm. As a result, the groove depth of the clamping portion 31 is 60% (=0.9 / 1.5) of the outer diameter of the tubular member 40. In other words, more than half of the radial direction of the tubular member 40 is fitted into the clamping portion 31. As described above, because the groove width of the clamping portion 31 is narrower than the outer diameter of the tubular member 40 and the groove depth of the clamping portion 31 is more than half of the radial direction of the tubular member 40, the clamping portion 31 can reliably clamp the tubular member 40 from the groove width direction.

[0023] As shown in FIGS. 6 and 7 , the display unit 11 is attached to the front panel 22 with the tubular member 40 fitted into the continuous groove 30. At this time, the tubular member 40 is crushed by the display unit 11. As a result, the gaps (gaps on the upper side and both the left and right sides) between the display unit 11 and each of the left edge 23A, right edge 23B, and upper edge 23C of the front panel 22 are closed by the tubular member 40. Furthermore, the gaps between the display unit 11 and each of the curved portions of the left edge 23A of the front panel 22 that curve from the lower end toward the lower edge 23D (the portion where the curved groove 30E is located) and the curved portions of the right edge 23B of the front panel 22 that curve from the lower end toward the lower edge 23D (the portion where the curved groove 30F is located) are closed by the tubular member 40. The front panel 22 with the display unit 11 attached is assembled with other components of the medical display device 1. When the front panel 22 is tilted at an angle of 15 degrees or less from the vertical direction and liquid falls and seeps into the gap, the gap is blocked from the top (+Y direction), right side (+X direction), and left side (-X direction) by the tubular member 40, so the medical display device 1 is not adversely affected by the liquid.

[0024] Next, a description will be given of the assembling operation of fitting the tubular member 40 into the continuous groove 30. Here, a description will be given of the assembling operation of fitting the tubular member 40 in a clockwise direction.

[0025] When assembling the tubular member 40, first, one end of the tubular member 40 is fitted along the curved groove portion 30E. Next, the tubular member 40 is fitted along the left groove portion 30A, the curved groove portion 30D, the upper groove portion 30C, the curved groove portion 30F, and the right groove portion 30B in this order. Finally, the other end of the tubular member 40 is fitted along the curved groove portion 30G.

[0026] In assembling the tubular member 40, the tubular member 40 is an elastic body having a constant cross-sectional shape, and the continuous groove 30 also has a constant cross-sectional shape. Furthermore, the continuous groove 30 has a constant cross-sectional shape, excluding the difference between the groove width of the clamping portion 31 and the groove width of the non-clamping portion 32. This allows any portion of the tubular member 40 to be aligned with the continuous groove 30. Furthermore, a small gap 33 (play) is provided between the groove wall of the non-clamping portion 32 and the outer periphery of the tubular member 40, allowing the tubular member 40 to automatically conform to the shape of the continuous groove 30. As a result, in assembling the tubular member 40 as a sealing member, it is only necessary to repeatedly fit the tubular member 40 into the continuous groove 30. Unlike conventional waterproof structures, the assembly work does not require the shape of the sealing member (sponge member) and the shape of the continuous groove 30 to be matched, and therefore does not require advanced skills. As a result, the ease of assembling the tubular member 40 can be improved. Furthermore, because each of the clamping portions 31 arranged at predetermined intervals in the continuous groove 30 clamps a respective portion of the tubular member 40 in the longitudinal direction from the groove width direction, the tubular member 40 will not come off the continuous groove 30. This eliminates the need to re-insert the tubular member 40 into the continuous groove 30, making it possible to improve the workability of assembling the tubular member 40.

[0027] Furthermore, during the assembly of the tubular member 40, particularly in the case of the curved grooves 30D, 30E, 30F, and 30G, the tubular member 40 fitted along each of the curved grooves 30D, 30E, 30F, and 30G is more likely to come off each of the curved grooves 30D, 30E, 30F, and 30G due to its restoring force than a tubular member 40 fitted into a linear left groove 30A or the like. However, because the clamping portions 31 located at both ends of each of the curved grooves 30D, 30E, 30F, and 30G clamp the tubular member 40 from the groove width direction, the tubular member 40 does not come off each of the curved grooves 30D, 30E, 30F, and 30G. This eliminates the need to refit the tubular member 40 into the continuous groove 30.

[0028] As described above, in the assembly work of the tubular member 40, the tubular member 40 can be automatically aligned with the continuous groove 30, so there is no need to perform the assembly work while matching the shape of the tubular member 40 with the shape of the continuous groove 30. Furthermore, because the clamping portion 31 is disposed at a predetermined position in the continuous groove 30, the tubular member 40 does not come off the continuous groove 30. This eliminates the need to re-insert the tubular member 40 into the continuous groove 30. As a result, it becomes possible to insert the front panel 22 into the display unit 11 from above, with the display unit 11 placed underneath. This also makes it easier to replace the front panel 22, improving maintainability.

[0029] The medical display device 1 of the above embodiment comprises a front panel 22 having a left edge 23A, a right edge 23B, an upper edge 23C, and a lower edge 23D, and having a continuous groove 30 with a U-shaped cross section that is arranged continuously at least along the left edge 23A, the right edge 23B, and the upper edge 23C; a display unit 11 that is attached to the front panel 22 and displays biological information; and a tubular member 40 that is fitted along the continuous groove 30 and is arranged so as to be tightly sandwiched between the continuous groove 30 and the display unit 11.

[0030] According to the above configuration, in the assembly work of fitting the tubular member 40 serving as a sealing member into the continuous groove 30, the tubular member 40 automatically conforms to the shape of the continuous groove 30, so the worker can simply repeat the work of fitting the tubular member 40 into the continuous groove 30, without requiring advanced skills. This makes it possible to improve the ease of assembling the tubular member 40. As in conventional waterproof structures, depending on the shape of the sealing member (sponge member), the yield of materials can decrease, which can increase manufacturing costs. However, in this embodiment, a tubular member is used as the sealing member, so there is no decrease in yield of materials and it is possible to reduce manufacturing costs.

[0031] Furthermore, in the medical display device 1 according to the above embodiment, clamping portions 31 that clamp the tubular member 40 in the groove width direction are arranged at predetermined locations in the groove length direction in the continuous groove 30. This prevents the tubular member 40 from coming off the continuous groove 30, eliminating the need to re-insert the tubular member 40 into the continuous groove 30, thereby improving the workability of assembling the tubular member 40. Furthermore, in the medical display device 1 according to the above embodiment, the groove width of the continuous groove 30 excluding the clamping portion 31 is equal to or greater than the diameter of the tubular member 40. This makes it easier to fit the tubular member 40 into the continuous groove 30 excluding the clamping portion 31, thereby further improving the ease of assembling the tubular member 40.

[0032] Furthermore, in the medical display device 1 according to the above embodiment, the clamping portions 31 are arranged at both ends in the groove length direction of each of the curved groove portions 30D, 30E, 30F, and 30G. As a result, even in the curved groove portion 30D where the tubular member 40 is particularly likely to come off due to the restoring force of the tubular member 40, the tubular member 40 does not come off each of the curved groove portions 30D, 30E, 30F, and 30G. This eliminates the need to re-insert the tubular member 40, thereby improving the workability of assembling the tubular member 40.

[0033] Furthermore, in the medical display device 1 according to the above embodiment, the groove depth of the clamping portion 31 is 60% or more of the outer diameter of the tubular member 40. This allows the clamping portion 31 to reliably clamp the tubular member 40 from the groove width direction, making it difficult for the tubular member 40 to come off the continuous groove 30.

[0034] In the medical display device 1 according to the above embodiment, the present invention has been described as being applied to a biological information display monitor having a display unit that displays biological information, but the present invention is not limited to this and may be broadly applied to, for example, a medical display device having a display unit that displays medical information.

[0035] Furthermore, the above-described embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be construed as being limited by these embodiments. In other words, the present invention can be carried out in various forms without departing from the gist or main features thereof. [Industrial Applicability]

[0036] The present invention is suitably used for a medical display device having a display main body portion that is required to have improved workability in assembling a sealing member. [Explanation of symbols]
