| 20120232412 | BLOOD PRESSURE MEASUREMENT DEVICE, CONTROL METHOD OF ELECTRONIC SPHYGMOMANOMETER AND CONTROL PROGRAM OF ELECTRONIC SPHYGMOMANOMETER - A sphygmomanometer, in a deflation process after inflation to prescribed pressure adjusts a drive voltage of an exhaust valve such that a deflation speed of a fluid bag achieves a prescribed deflation speed during an adjustment period, which is a prescribed period after starting deflation. When the adjustment period ends or when the deflation speed of the fluid bag achieves the prescribed speed, control is subsequently performed to fix the drive voltage of the exhaust valve and deflate the fluid bag while holding a gap of the exhaust valve constant. | 09-13-2012 |
| 20120271179 | FEMORAL COMPRESSION DEVICE - A femoral compression device ( | 10-25-2012 |
| 20130178752 | VALVE, FLUID CONTROL DEVICE - In a fluid control device, a check valve includes a first valve housing and a first diaphragm. The first diaphragm defines a first valve chamber and a second valve chamber. An exhaust valve includes a second valve housing and a second diaphragm. The second diaphragm defines a third valve chamber and a fourth valve chamber. The check valve is opened and closed by a difference in pressure between the first valve chamber and the second valve chamber. The exhaust valve is opened and closed by a difference in pressure between the third valve chamber and the fourth valve chamber. | 07-11-2013 |
| 20130226014 | SPHYGMOMANOMETER WITH ACCESSORY LOW-SPEED PRESSURE RELEASE DEVICE - A sphygmomanometer with an accessory low-speed pressure release device comprises: a main body, having a multi-channel pipeline, and a pressure pump coupled to the multi-channel pipeline; a circuit device, including a microprocessor and a pressure sensor, and the pressure sensor is coupled to the multi-channel pipeline, and the circuit device is coupled to the pressure pump through an electric circuit; a cuff device, coupled to the multi-channel pipeline through an air channel; and an accessory low-speed pressure release device, installed on the air channel and disposed outside the main body, so that the accessory low-speed pressure release device is adjusted according to the cuffs of different sizes and operated at an optimal air release speed to obtain measurements more quickly and accurately when cuffs of different sizes are used. | 08-29-2013 |
| 20130331715 | FLOW RATE CONTROL VALVE AND BLOOD PRESSURE INFORMATION MEASUREMENT DEVICE INCLUDING THE SAME - A flow rate control valve includes a casing provided with an inlet port and an outlet port through which a fluid, the flow rate of which should be controlled, flows in and out, a diaphragm that partitions a space inside the casing into a flow space in which the fluid flows and a working space in which a working medium is present, and a valve body provided on a portion of the diaphragm that opposes the inlet port. The diaphragm is displaced in accordance with a change in the internal pressure of the working space, and the valve body is accordingly moved. This results in a change in the distance between the valve body and the inlet port, and thus the flow rate of the fluid flowing into the flow space through the inlet port is adjusted. Therefore, the flow rate of the fluid flowing out through the outlet port is variably controlled. | 12-12-2013 |
| 20150038859 | BLOOD PRESSURE MONITOR WITH VALVE-CHAMBER ASSEMBLY - A blood pressure measurement system is provided that includes an inflatable cuff, a valve assembly and chamber assembly. The chamber assembly can house a gas canister for providing gas to the inflatable cuff. The valve assembly can include a valve having a high pressure cavity, a low pressure cavity, and a channel providing a gas pathway between the high pressure cavity and the low pressure cavity. The valve assembly can further include a channel cover and spring in the high pressure cavity. The spring can exert a force on the channel cover to create a seal between the high pressure cavity and the channel. The valve assembly can further include a rod extending through the channel and exerting a force on the channel cover to create a gas pathway between the high pressure cavity and the channel. | 02-05-2015 |
| 20150088009 | SEMI-AUTOMATIC SPHYGMOMANOMETER SYSTEM - An embodiment of a semi-automatic sphygmomanometer apparatus that provides a means for initiating and terminating inflation of a vascular cuff is disclosed. The semi-automatic sphygmomanometer apparatus includes a motor that operates a pump which generates air pressure to inflate the vascular cuff, wherein operation of the pump is initiated when the inflationary button is depressed and wherein operation of the pump is terminated when the inflationary button is released. | 03-26-2015 |
| 20160120417 | SOLENOID VALVE AND ELECTRONIC BLOOD PRESSURE MONITOR EQUIPPED WITH THE SAME - In a solenoid valve, a bobbin and a solenoid coil are accommodated in a casing. A rod-shaped plunger is slidably inserted into the bobbin. A core provided with a flow port through which a fluid flows is disposed on one side of the casing. A valve body is attached to one end opposing the flow port of the plunger. In a non-operating period during which a solenoid coil is in a non-energized state, the valve body moves away from the flow port due to the biasing force applied by the biasing portion and another end of the plunger protrudes outward from the casing through the through hole, abuts against lock portions disposed outside of the casing, and is thereby locked. The lock portions can be elastically deformed by an external force such that separation of the plunger and the valve body from the casing is allowed. | 05-05-2016 |
| 20160128585 | Medical Device - A carrier assembly includes a sub-assembly including a pump, at least one solenoid valve, and a check valve. The pump, the at least one solenoid valve, and the check valve are in fluid communication with each other and with at least one pressure transducer via a manifold. Also, the carrier assembly is configured to be mounted to a medical device's main assembly board. | 05-12-2016 |
