Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electronic blood pressure monitor in which a main body case housing a blood pressure measurement circuit is integrated with a cuff wrapped around the arm of a subject.

(B) Prior Art Conventionally, this type of electronic blood pressure monitor has a wrist cuff wrapped around the arm of the patient and a main body that houses the blood pressure measurement circuit, which are separately provided, and both are connected by a rubber tube with a signal transmission line. Those that did were common. However, according to this conventional method, the arm cuff and the main body are separate, making it difficult to carry, and furthermore, the pressurized pressure of the arm cuff is transmitted to the main body using a long rubber tube with a signal transmission line, making measurement difficult. There is a risk that sensitivity will deteriorate and reliability will decrease.

(C) Purpose of the Invention The blood pressure monitor of the present invention has good portability by integrating the body case housing the blood pressure measurement circuit with the arm cuff, and also provides a microphone for detecting Korotkoff sounds by attaching the cuff to the arm. can be worn in 14 positions on the arm at the same time.

B) Structure of the Invention The sphygmomanometer of the present invention has a curved bottom surface formed to follow the arm of the subject, and includes a main body case that houses a blood pressure measurement circuit inside, and a sound collecting surface that extends along the arm of the subject. It is equipped on the curved bottom part so as to face the subject, and houses the subject's Korotkoff sound and cuff band, and has a base part and a free end part attached to both ends of the curved bottom part, and is wound around the arm. It is characterized by having a cloth bag arm cuff.

(E) Function: Therefore, simply by attaching the cuff to the patient's arm, the main body case of the blood pressure monitor can be attached to the arm at the same time.Furthermore, the air tube connecting the cuff band and the blood pressure measurement circuit can be short, which improves measurement sensitivity. The device does not deteriorate, and the microphone embedded in the curved bottom of the blood pressure monitor accurately detects Korotkoff sounds.

(v) Example +1) is the main case of the blood pressure monitor of the present invention, and the upper case (2)
and a lower case (3).

In the lower case (3), (4) is a rectangular housing-like base having a lower storage part (5) with an upper opening and a bottom surface (6) having a curved cross section, and (7) is this base. The bottom of (4)! 6
1 K screw (8) is fixed to the armature body that covers a part of the bottom surface (6), and the armature body (6) is attached to the subject's arm (A).
an outer surface (10) having a curved bottom surface (9) formed along the bottom surface (9) and abutting the bottom surface (6) of the base (4);
Grooves (11) (II) are perforated in the circumferential direction, and sound collection through holes (12) extending from the outer surface (10) to the curved bottom surface (9) are provided therethrough. (131 is a thin film diaphragm, α is a sound collection cavity (a diaphragm valve with +61,
As shown in FIG. 6, the through hole (12) K and the diaphragm (1
The diaphragm (131) is stretched over the curved bottom surface (9) by fitting the periphery of the diaphragm valve (14) through 4. (1φ is this diaphragm valve 04) This is a condenser microphone embedded in the bottomless microphone storage recess θ with the sound collecting surface (16a) facing the subject's arm, that is, facing the diaphragm (131).(+8) is an arm cuff mounting bracket made by bending a wire into a square shape and along the groove (11), and the arm cuff body (7) is sometimes attached to the base (4) by the groove. By fitting it into the strip (11), it is held between the armature body (7) and the base body (4). (19) is a rubber cuff band having an air pipe; ]) A durable cloth bag armband that stores a dovetail cuff band (+9), and the armband (21) has its base (z 1a) attached to one end (18a) of the metal fitting (1). Further, the upper case (2) has an upper storage part with a lower opening that closes the lower case (3), and has an upper rear portion raised in the shape of a triangular prism. Display window (2) fitted with display lens (%)

The cuff band connecting tube 14z and the pressurized air tube (43 The pressurizing rubber bulb 144) is communicated with a slow exhaust valve (4G) inserted into the connecting hole.

Then, insert the armature body (7) on the bottom of the main body case (1) into the diaphragm (131 is just the other end Qsb of the test subject instrument α) for the microphone (1), and fold it back. By doing so, the main body case fl) is attached to the arm (A) together with the arm cuff (21), and after a, the pressurizing rubber bulb (44) is operated to send pressurized air to the arm cuff (19), and the arm cuff (21) is attached. Once the arterial blood vessel is ischemized, the pressurized air is exhausted by the slow exhaust valve (4G), and when the Korotkoff sound is detected by the microphone outlet, the pressure sensor The air pressure of the pressure sensor □) when it is no longer detected by the microphone sound is displayed on the digital display (341) as the diastolic blood pressure value.

(g) Effects of the Invention Therefore, according to the present invention, the blood pressure monitor main body case is attached to the arm of the subject together with the arm cuff, so portability is very good, and the main body case can be attached to the arm to detect Korotkoff sounds. The microphone is also positioned and attached to the arm at the same time, making it extremely easy to use.Furthermore, since there is no need for a long air pipe between the cuff band and the pressure sensor, unlike conventional methods, the measurement sensitivity is good and accurate. It is possible to obtain accurate systolic and diastolic blood pressure values.
