比較して約10dB（Ａ特性）低減された。 The present invention will be explained below according to one embodiment. FIG. 1 shows a top view of the overall configuration of a diaphragm type blood pressure monitor pump employing the present invention. A hex pin 6 attached to the shaft of a motor 7 is inserted into a hex pin insertion portion 9 of the diaphragm 1. The diaphragm 1 is held between a base 2 and a cover 3, and the cover 3 is attached to the base 2 with cover attachment screws 11. Similarly, the motor 7 is also fixed to the base 2 with a motor support plate 8. In this embodiment, a diaphragm is used in which the diaphragm portion and the exhaust side and intake side valve bodies (none of which are shown) are integrally formed of an elastic body. FIG. 2 is a perspective view of FIG. 1. As shown in the figure, a sound insulating wall 10 with a height equal to or higher than the center of the motor rotation shaft 12 is provided on the outer periphery of the cover 3 so as to surround the diaphragm 1 and the valve body, which are the sound sources, except for the part where the shaft of the motor 7 passes through. It is formed integrally with 3. According to the pump having such a configuration, the sound insulating wall 10 blocks horizontal propagation of the sound generated by the up-and-down reciprocating movement of the diaphragm 1 and the reciprocating movement of the intake and exhaust valves. FIG. 3 shows an external view of a blood pressure monitor incorporating a pressurizing pump unit of this configuration. Operation switch 15 and display section 1 are on the front side of the figure.
6 are arranged. Figure 4 shows the AA shown in Figure 3.
FIG. As shown in the figure, the upper opening of the cover 3 of the pressurizing pump unit described above is formed with a sound insulating wall by the control board 17 and the display board 18, and the propagation of sound from the upper opening is greatly reduced. be able to. According to the configuration of the present invention,
By forming the sound insulating wall 10 integrally with the cover 3, and by using a circuit board disposed inside for sound insulating the upper open height part, it is not only inexpensive without requiring separate parts, but also easy to assemble. It's very good. Of course, there are gaps between the sound insulating wall 10 and the joints of each circuit board, and complete sound isolation is not possible, but the leakage of sound from there is kept away from the case 13.
and 14, it is at a level that can sufficiently insulate sound, and the structure described above can provide sufficient effects. The sound pressure level at a horizontal distance of 50 cm from the surface where the operation switch 15 of the blood pressure monitor with the above configuration is installed is approximately 10 dB (A characteristic) compared to the configuration without any sound insulation measures. Reduced.

い。 In the embodiment described above, the sound insulating wall 10 is formed integrally with the cover 3, but the present invention is not limited to this, and the same effect can be obtained even if the sound insulating wall 10 is formed separately. Further, in this embodiment, the sound insulating wall is composed of two circuit boards, but the present invention is not limited to this, and it may be composed of one board. Further, the configuration of each part of the pump unit, the external shape of the blood pressure monitor, etc. do not affect the effects of the present invention.
