Embodiments of the present invention will now be described with reference to the drawings. 1 to 5 show an embodiment in which the present invention is applied to an electronic blood pressure monitor for a finger. FIG. 1 is an exploded perspective view of the electronic blood pressure monitor, FIG. 2 is a vertical sectional view of the blood pressure monitor, and FIG. A perspective view of a cuff connector integrated air socket, which is a main part of an air supply / discharge path,
4 is a vertical sectional view of the socket, FIG. 5 is a perspective view of an assembly portion of the socket with a sphygmomanometer main body case, and FIG. 6 is a sectional view of the socket with an inspection jig inserted.

In these drawings, reference numeral 10A is a container-shaped lower case of the sphygmomanometer body, and the cuff 1 is placed in the lower case 10A.
4, the cuff holder 12 to which 4 is attached, the feeding / discharging mechanism 20 constituting the air feeding / discharging path, the printed circuit board 60, and the like are accommodated, and the lid-shaped sphygmomanometer main case 10B is the lower case 1
It is engaged with 0A and integrated as a sphygmomanometer body.

The air supply / discharge mechanism 20 includes an air pump 22 which is a compressed air supply source for the cuff 14, an air socket 30 provided in an air supply / discharge path between the air pump 22 and the cuff 14,
It is composed of a pressure sensor 24 for detecting the cuff pressure and an exhaust valve 26 for adjusting the cuff pressure. Exhaust valve 26
Is a structure that allows the exhaust to be adjusted at two speeds, high speed exhaust and low speed exhaust. Compared to the case where the conventional high speed exhaust valve and low speed exhaust valve are independently provided, the air tube is connected. It's easy. Then, in the air socket 30 fixedly held on the bottom surface of the lower case 10A in an upright state, the base 15 of the cuff 14, the air tube 25 extending from the pressure sensor 24, the air tube 27 extending from the exhaust valve 26, the air tube extending from the air pump 22. 23 are connected to each other.

As shown in FIGS. 3 and 4, the air socket 30 is a cylindrical body whose upper end is closed, and the air tube attachment portions 31 and 3 that project horizontally to the outer surface of the air socket.
2 and 33 are arranged in a line in the vertical direction, and the air tube attachment portions 31, 32, and 33 are arranged in this order from the top to the pressure sensor air tube 25 and the exhaust valve air tube 2.
7. The air tube 23 for the air pump is attached. Further, a cuff attachment portion 34 is formed so as to project at the same height as the lowermost air tube attachment portion 33, and the mouthpiece 15 of the cuff 14 is attached directly to the cuff attachment portion 34. The air tube between the air socket and the cuff of the structure is omitted. In this way, the air tube attachment parts 31 to 31
Since 33 are arranged in series, the air tubes 23, 25, 27 connected to the air socket 30 are aligned in the vertical direction. The air tubes 23, 25, 27 and the air tube attachment portions 31 to 33 are connected to each other in order to prevent the air tubes from crossing each other, as shown in FIG. Although the air tube is connected in accordance with the positions of 22, the exhaust valve 26, and the pressure sensor 24, the air tube attachment parts 31 to 33 are connected.
Since the air ports 31a to 33a formed in 1 are communicated with each other in the air passage 35 in the air socket 30, even if the air tubes 23, 25 and 27 are attached to any of the air tube attachment portions 31 to 33. Often, this arrangement simplifies the work of connecting the air tube.

An air passage 35 extending downward is formed in the air socket 30, and air tube attachment portions 31, 32, 33 and a cuff attachment portion 34 are formed on an inner peripheral surface of the air passage 35.
Corresponding to the air ports 31a, 32a, 33a, 34a
Is open. Between the air ports adjacent to each other in the upper and lower portions of the air passage 35, steps 36a and 36b having a smaller inner diameter toward the upper side are formed.
Is formed, and the air passage 35 has a stepped concentric columnar shape having a smaller inner diameter toward the upper side. An opening 37 is provided at the lower end of the air socket 30 and is continuous with the air passage 35. Usually, the opening 37 is provided with a removable cap 38.
Is inserted and attached to maintain the air passage 35 in the air socket in a hermetically sealed state. Reference numeral 37a is a rib provided around the inner peripheral surface of the opening 37, and a cap 38 is attached to the rib 37a.
, The cap 38 is prevented from coming off,
As a result, the air socket 30 is held upright without rattling with respect to the lower case 10A.

A pair of plate-shaped slide pieces 39, 39 are formed at the lower end of the air socket 30 so as to project therefrom. The slide pieces 39, 39 are formed in the lower case 1 of the sphygmomanometer body.
It is gripped by gripping claws 41, 41 protruding upward from the bottom surface of 0A. That is, as shown in FIG. 5, inside the bottom surface of the lower case 10A, as shown in FIG.
The slide pieces 39, 39 of the air socket 30 are slide-fitted between the grip claws 41, 41, the slide pieces 39, 39 are gripped by the grip claws 41, 41, and the cap 38 is inserted. As a result, the slide piece 39 is sandwiched and fixed between the grip claw 41 and the bottom surface of the case. An opening 37 is formed in the central portion between the grip claws 41 on the bottom surface of the lower case of the main body.
And an opening 42 corresponding to the opening 4 is formed.
The cap 38 can be inserted and removed via the connector 2.

Further, as shown in FIG. 6, the cap 38
Can be removed, and an inspection jig indicated by reference numeral 50 can be inserted into the opening 37 from the opening 42 on the bottom surface of the case to inspect air leakage from the air tube or the pressure sensor and the linearity of the pressure sensor. . That is, as described above, since the air passage 35 has a stepped shape in which the inner diameter is smaller toward the upper side, the inspection jigs having different outer diameters at the tip end are provided with the air passages 3.
5 can be inserted to close an arbitrary air port, so that an air leak in an arbitrary air supply / discharge path can be inspected. Reference numeral 43 is a slide die slide hole formed on the bottom surface of the case for molding the grip claw 41.

Although the present invention has been described with reference to the electronic blood pressure monitor for the finger in the above-mentioned embodiment, it goes without saying that the same can be applied to the electronic blood pressure monitor for the arm.
