  • the pneumatic system and the electrical system were constructed as independent units such troubles as twisting tangling of the rubber tube and cable were inevitable.
  • an air bulb and an arm band containing or bonded to a rectangular rubber bag connected to a pressure meter are generally used. Doctors, nurses or specially trained persons can readily handle the blood pressure meter, but from the standpoint of health control it is desirable that unskilled persons can use such blood pressure meter without the aid of a specialist.

  • FIGS. 1, 2 and 3 A preferred embodiment of this invention shown in FIGS. 1, 2 and 3 comprises an elongated hollow casing l or main body made of a synthetic resin such as ABS (Acrylonitrile-Butadiene-Styrene) resin or vinyl chloride resin.
  • a pressure meter 2 is mounted on the top of the casing 1 parallel to or at a predetermined angle with respect to the longitudinal axis of the casing 1.
  • An air bulb 5 is seated in a recess at one side of the casing near the bottom thereof and an air pressure adjusting knob 8 in the form of a dial position is located on the opposite side of the air bulb.
  • a source switch 6 and a connector 7 are provided at the bottom of the casing l for attachment to an air supply pipe 11 and electric terminals 12. There is also provided a volt meter 9 for indicating the voltage of a source and a plurality of screws 10 are used to hold the casing 1.
  • a hybrid type integrated circuit 13 is contained in the bottom of the top of the casing 1, and a power source in the form of batteries 26 is contained in the hollow casing just behind the air bulb 5.
  • the battery may be recharged when discharged so that it is not necessary to replenish it frequently.
  • the electric system of the blood pressure meter comprises terminals 12 to be connected with a microphone to be described later, the integrated circuit 13 described above, and a light source 17 in the form of a display lamp.
  • the signal detected by the microphone is sent to the integrated circuit 13 via terminals 12 to be amplified by the integrated circuit to form a pulse which is used to light the display lamp for indicating to the observer the correct time at which the blood pressure is measured.
  • the pneumatic pressure applied to the upper arm of a patient for measuring the blood pressure is provided by the following pneumatic system.
  • air is sucked into the bulb 5 through an intake port 24 and compressed air is admitted into the pressure meter through pipes 22 and 21 and into the inflatable rubber bag of an arm band to be described later via a pressure regulating valve 19 and pipes 20 and 11 so as to indicate the pressure in the rubber bag by the deflection of the pointer of the pressure meter.
  • the pressure meter is housed in a casing 23.
  • the blood pressure meter of this invention constructed as above described it is possible to grasp by a single hand both the central portion of the casing 1 and the air bulb 5 so that by repeating compression and release of the air bulb it is possible to apply pressurized air to the arm band while observing the pressure meter.
  • Another feature of this invention lies in an improved construction of the display member of the pressure meter 2. More particularly, an inclined surface 16 having an inclination angle 0 (45 in the example illustrated) is formed around the periphery of a transparent base plate 15 made of glass or acrylic resin, and a light shield plate 18 having a diameter smaller than that of the base plate 15 so that the inclined surface 16 will not be covered by the shield plate is superposed upon the base plate 15.
  • the scale (not shown) of the pressure meter is graduated on the periphery of the base plate 15. It should be understood that the light shield plate 18 may be substituted by a coating of an opaque coating material.
  • An opening is formed at a suitable portion of the base plate 15 to receive the light source 17 in the form of an incandescent lamp or a luminous diode.
  • the arm band comprises a hollow bag 27a comprising a plurality of sheets of cloths which are sewed together and an inflatable rubber bag 28 contained in the bag 27a and connected to an air supply pipe to be described later.
  • a microphone 33 is disposed between the bag of cloth 27a and the rubber bag 28.
  • a longitudinal pocket 30 is formed on one side of the arm band to receive a spring member 31 having a construction as shown in FIG. 7.
  • a reenforcing member 32 is provided on one side of the arm band and adhesive tapes 29 are bonded to the arm band at the opposite ends thereof on the opposite surfaces.
