The plug 6 is provided with a protruding spring receiving piece 51, and the spring receiving piece 51 is provided with a locking recess 52.

11 and 12.
As shown in the figure, when the spring receiving piece 51 is inserted into the insertion openings 2 and 8 of the insertion block 12, the spring receiving piece 51 is also inserted into the insertion gap 49, and the locking protrusion 59 and the locking recess 52 are locked.

This not only prevents the plug 6 from coming out, but also prevents the insertion tubes 7 and 1.
It is possible to confirm whether the plug 6 is inserted to a predetermined position and securely sealed, and furthermore, when the plug 6 is turned upside down and tried to be inserted, it does not enter, making it possible to provide directionality for attachment and detachment.

Furthermore, as shown in FIG. 13, hook protrusions 53 are provided on both sides of the insertion block 12, and insertion curves 54 are formed on both sides of the insertion block 12.

A notch 55 into which the insertion block 12 can be inserted is provided in the component mounting plate 22 of the blood pressure monitor body 10, and frame-shaped hooked portions 56 are protruded from both sides of the notch 55.

Then, as shown in FIG. 14, the insertion block 12 is inserted into the notch 55, both side edges of the notch 55 are inserted into the insertion groove 54, and the hooking protrusion 53 is hooked onto the hooked portion 56.

In this way, the insertion block 12 can be easily installed without using screws.

To use the blood pressure monitor formed as described above, first, insert the insertion tube 1 and the insertion tube 10 of the plug 6 into the insertion port 2 and the insertion port 8, respectively, and connect them. Turn on.

Next, wrap the cuff band 4 around your arm and press the start operation switch knob 33 to activate the pump 14.
, air is sent into the cuff band 4, the arm is tightened by the cuff band 4, and the Korotkoff sound is detected by the microphone 18 via the sound collection tube 9.

When the generation of this Korotkoff sound disappears, the operation of the pump 14 is stopped, and the solenoid valve 16 is activated so that the cuff band 4
The air inside begins to escape.

In this way, the air gradually escapes from the cuff band 4 and the tightness on the arm begins to loosen, and the microphone 18 detects the first Korotkoff sound, and the pressure detector 15 detects the air pressure in the cuff band 4 at this time. , the systolic blood pressure is digitally displayed on the display panel 37 as shown in FIG. is detected and digitally displayed on the display panel 37 as the lowest blood pressure.

The present invention provides a blood pressure monitor body as described above with an insertion port for cuff pressure and an insertion port for sound collection in parallel, and connects the ends of the cuff pressure tube and sound collection tube that can be led out from the cuff band to the plug. The plug is equipped with an insertion tube for cuff pressure and an insertion tube for sound collection, and the pair of insertion tubes are inserted into the pair of insertion ports, so just by inserting and removing the plug, the blood pressure monitor body and cuff band can be connected. It is easy to use as it can be connected to and removed from the cuff pressure tube and the cuff pressure tube. The sound collection tubes can be connected and disconnected at the same time, making it even easier to handle, and since a pair of insertion tubes are inserted into a pair of insertion ports, you only need to insert one insertion tube into one insertion port. It is less likely to come off than the other type, and can be connected more reliably, and the gap between the insertion port for cuff pressure and the insertion tube for cuff pressure is sealed with a compression type packing such as an O-ring, and the insertion tube for collecting sound is sealed. A lip-shaped gasket seals between the mouth and the sound-collecting insertion tube, which not only reliably prevents cuff pressure from leaking, but also provides a rough seal on the sound-collecting side, which is less susceptible to leakage. This can absorb the sagging of the two insertion tubes of the plug.

Furthermore, in the combined invention of the present invention, the insertion block is divided into two parts, the first block and the second block, and the packing to be attached to the insertion opening is attached to the divided part, so that there is no problem inside the insertion opening. The packing can be easily attached even if the
