  • Patent number: 6336901
    Abstract: A cuff for a sphygmomanometer is constituted of an air bag for pressurization into which a predetermined amount of air is supplied and connected to a pressure sensor, an air bag for press into which a predetermined amount of fluid is supplied for causing the pressurization air bag to press the artery in the wrist portion, and a band for attaching both air bags to the wrist portion. When blood pressure is to be measured, a predetermined amount of air is supplied into the pressurization air bag and then air is supplied into the press air bag. The press air bag is accordingly expanded to cause the pressurization air bag to pressurize the artery. In this way, the sphygmomanometer cuff is provided which can overcome discomfort due to a feeling of being overly pressurized or dampness and ensure blocking of the blood flow in the artery so as to achieve measurement with higher precision.

  • Patent number: 6309359
    Abstract: An occlusive cuff is placed around a limb (e.g. an arm) of a patient. A fluid, such as air, is pumped into the cuff, and the pressure in the cuff is measured. The pressure variation in the cuff with respect to time is caused by the pump and expansion/contraction of the arm caused by blood being pumped therethrough by the patient's heart. This variation in pressure is used to calculate systolic and diastolic pressure, artery lumen area compliance and artery volume compliance, artery lumen area, and the blood flow rate through the patient's arteries (e.g. the brachial artery for the case of the patient's arm, or the femoral artery or the case of the patient's leg).

  • Patent number: 6228036
    Abstract: The present invention is directed to an electronic sphygmomanometer for determining a blood pressure depending on variation in pulse wave amplitude variation waveform and cuff pressure formed by variation in the amplitude of the pulse wave, comprising: detecting the pulse wave amplitude and cuff pressure when the pulse wave exceeds a first threshold to define a first threshold; detecting the pulse wave amplitude and cuff pressure when the pulse wave exceeds a second cuff pressure to define a second point; and then, calculating a pulse wave amplitude linear equation for connecting the first and the second points to obtain a systolic blood pressure value. According to the invention, the electronic sphygmomanometer is capable of precisely measuring a blood pressure even if dispersion occurs in pulse wave amplitude depending on how to mount the cuff or even if there is certain distortion in pulse wave depending on the physical conditions of a subject.

  • Patent number: 6213953
    Abstract: An improved ausculatory blood pressure cuff, of the type used in self-testing locations, operates with no moving parts other than the inflatable bladder. No springs or mechanical motors are used to close the bladder portion of the machine around the arm of the user. A generally cylindrically shaped housing is mounted on a base support. The housing has an opening where it is mounted onto the base support; and a hollow fabric sleeve, having a first portion releasably attached to the interior of the cylindrical housing and having a second portion spaced from the first portion located on the interior of the housing, is placed in the housing. An inflatable bladder is located in the space between the two portions of the hollow sleeve; and air is supplied under pressure to inflate the bladder to predetermined pressures. When this is done, the bladder and sleeve expand to constrict the space in the cylindrical housing to close the bladder and sleeve about the arm of a user.

Devices. The prototype of this unit consists of an electrical/pedal pumps combined with a manual inflation units. This will allow the electrical/pedal pumps to be used first for inflation of most of the inflatable part and then the manual unit will be used for a lesser degree of inflation as well as the adjustment of the inflation units. This combination is to prevent straining of the hands. It will also allow quick and easy action. This unit also allows a trigger system to be used for controlling the pressure in the system to prevent from the discomfort of the rotational action; it also has safety valves to prevent the pressure from exceeding a predicted level.
