As shown in FIG. 4, the air unit 20 includes a housing 22, an air pump 24, a driving motor 26, an exhaust module 28, a switch unit, a control circuit unit 30, and a power supply unit. It includes an organic bonding structure.

The housing 22 forms the outer shape of the air unit 20. The housing 22 is in the form of a bulb corresponding to a pump in the form of a bulb that supplies air in a conventional apparatus. Accordingly, in the conventional blood pressure measuring device, only the bulb-type pump may be replaced with the air unit 20. The shape of the housing 22 is not particularly limited to the shape of the bulb and may be variously modified. In addition, the housing 22 may be made of a rubber material, and may be made of various materials such as plastic.

At one end of the housing 22, the coupling hole 23 is formed to protrude so that the air hose 13 connected to the arm 12 is fitted. The coupler 23 has a structure in which a tooth-shaped uneven portion is formed on a surface thereof to increase the bonding force with the air hose 13.

In addition, in the present embodiment, the housing 22 is divided into two spaces by the partition wall 25 installed therein, and in one space, the air pump 24, the driving motor 26, the switch part, and the control circuit part. 30 is built-in and the power supply unit is disposed in the remaining space. This is for the removal of the power supply unit will be described later.

The air pump 24 discharges air by generating pneumatic pressure through the rotational force of the driving motor 26. The air pump 24 supplies air generated in communication with the coupling hole 23 of the housing 22 to the air hose 13 through the coupling hole 23. The drive motor 26 is operated according to the signal of the control circuit to drive the air pump 24.

In the present embodiment, the exhaust module 28 is installed between the air pump 24 and the coupling port 23 on the outside of the housing 22. The exhaust module 28 has a structure in which the exhaust switch 29 is installed to the outside to discharge the air inside the connection hose 13 communicated through the coupler 23 according to the operation of the exhaust switch 29 to the outside. It is. The exhaust switch 29 may have a structure of a rotary method, a push or pull method, or a slide method, and is not particularly limited.

The switch unit is installed at one side of the housing 22 to operate the driving motor 26 according to the user's pressing operation. The switch unit is connected to the control circuit unit 30 to operate the main motor 32 and the intermittent switch for intermittently operating the drive motor 26 connected to the control circuit unit 30 ( 34).

The main switch 32 and the intermittent switch 34 installed inside the housing 22 are exposed to the outside through a hole 35 formed in the housing 22 so that the user can press them. In the present embodiment, the hole 35 formed in the housing 22 is provided with a cover 36 surrounding each switch 32 and 34 and blocking the hole from the outside.

The control circuit unit 30 is a circuit board having an internal circuit pattern formed thereon and forming a logic circuit, and is electrically connected to each switch, the driving motor 26, and the power supply unit. Accordingly, when the power applied from the power supply unit is selectively applied to the drive motor 26, the drive motor 26 is controlled to operate.

The power supply unit includes a secondary battery 40 provided in the housing 22 and a charging terminal 42 connected to the secondary battery 40 to apply charging power to the secondary battery 40. In this embodiment, the housing 22 is detachably installed at the end of the cover 44, the secondary battery 40 is embedded in the space between the cover 44 and the housing 22. The cover 44 forms part of the outer shape of the housing 22.

The secondary battery 40 is a battery that stores external electrical energy in the form of chemical energy and then repeatedly charges the battery to generate electricity when needed.

A male screw 45 and a female screw 46 are processed on the fastening surface between the cover 44 and the housing 22 so as to be screwed together. Accordingly, the cover 44 can be attached to and detached from the housing 22 by a screwing method. The internal terminal 41 installed in the secondary battery 40 is electrically connected to the (+) terminal 47 and the (-) terminal 48 of the control circuit unit 30 protruding through the partition wall 25.

Here, the connection between the terminals 47 and 48 and the internal terminal 41 of the secondary battery 40 may be applied in various structures.

When the power cable is connected through the charging terminal 42 installed in the cover 44 from the outside it is possible to charge the secondary battery 40 as required by receiving external power.

With the above structure, after wrapping the arm 12 in the measurement part, the user can inflate the arm 12 only by pressing the main switch 32 installed in the housing 22 of the apparatus. When the main switch 32 is operated, the control circuit unit 30 receiving the signal of the main switch 32 applies the power of the secondary battery 40 to the driving motor 26. The drive motor 26 is rotated to operate, and the air pump 24 connected to the drive motor 26 is operated to pump air into the air hose 13. The air generated from the air pump 24 is supplied to the air hose 13 through the coupler 23 at the tip of the housing 22 and supplied to the arm 12 connected to the air hose 13. The arm 12 is inflated to compress the blood pressure measurement site. When sufficient air is supplied to the arm 12, the main switch 32 is turned off to cut off the power applied to the driving motor 26. When the pressure necessary for blood pressure measurement is insufficient after turning off the main switch, the intermittent switch 34 is operated to compensate for the insufficient amount of pressure. When the intermittent switch 34 is operated, the control circuit unit 30 controls the driving motor and the air pump by a predetermined amount to apply pneumatic pressure as a band.

In this case, the switch 22 is installed in the form of a bulb such as a conventional pump, the user can perform the switch operation as described above in a state where the housing 22 is easily gripped in the hand.

In this way, the air can be supplied to the apparatus only by the switch operation. In this process, when the pressure for measuring blood pressure is insufficient, the intermittent switch 34 may be operated to supply additional air.

On the other hand, the present pumping device 50 for supplying air to the blood pressure measuring device is the same as the structure of the air unit 20 for supplying and exhausting air to the arm 12 in the blood pressure measuring device. Therefore, since the description of the structure of the present popping device 50 is the same as already mentioned, a detailed description thereof will be omitted. The pumping device 50 has the above-described structure so that the air supply can be mechanically supplied when the air pump 13 is connected to the air hose 13 instead of the bulb-type pump provided in the conventional blood pressure measuring device.

This device is made in the form corresponding to the conventional bulb-type pump in this way can be used by the user without a particular sense of rejection, the air supply is made only by pressing the switch operation.
