The said finger arteriotony of this embodiment continuous detecting adopts the sensing device structure of three-dimensional shape with sensing device.In the structure, the shape of hollow cuff 2 is a solid figure.It simultaneously sticks on the ABS plate (Acrylonitrile-butdiene-styrene, acrylonitrile/butadiene/styrene copolymer plate) with curved shape, has formed the very big arc substrate 1 of rigidity.And another side and people's finger has roughly the same radius of curvature, and when in hollow cuff 2, pumping into air, the expansion of hollow cuff 2 can effectively compress the skin of the finger section that is touched, and the pressure of hollow cuff 2 is delivered on the blood vessel wall to greatest extent.What the photoelectric sensor of being made up of light emitting diode 6 and photodiode 7 adopted is elastic construction.Light emitting diode 6 is bonded in respectively on the medial surface of hollow cuff 2 and contact skin side with 7 two photoelectric cells of photodiode, and light emitting diode 6 becomes roughly 45 configuration with 7 on photodiode.And light emitting diode 6 is connected with arc substrate 1 through the soft U type of the LED that becomes U font circuit board 9, and photodiode 7 is connected with arc substrate 1 through the soft U type of the PD that becomes U font circuit board 10.When pumping into air in the hollow cuff 2, hollow cuff 2 and contact skin one side are because the expansion of hollow cuff 2 makes the distance elongation of light emitting diode 6 and photodiode 7 photoelectric cells and 1 of arc substrate.On the other hand, light emitting diode 6 and photodiode 7 are connected through U font flexible circuit board and arc substrate 1, and the position of light emitting diode 6 and photodiode 7 is changed in certain scope.Like this, when hollow cuff 2 expanded, light emitting diode 6 outwards extended with hollow cuff 2 with photodiode 7, is adjacent to the skin that detects the position all the time; When hollow cuff 2 was leaked, the elasticity of the soft U type of LED circuit board 9 and 10 two U fonts of the soft U type of PD circuit board flexible circuit board can retract hollow cuff 2, loosened 2 pairs of compressings that detect position skin of hollow cuff.Therefore, light emitting diode 6 and photodiode 7 unstability that variation brought owing to optical path distance when blood pressure detects have been avoided.Simultaneously, the comfortableness of detection also increases.In addition, pressure transducer 8 directly is connected with hollow cuff 2 through the aperture at arc substrate 1 back side of ABS sheet material matter, and the accuracy of detection of gas pressure is high in the hollow cuff 2, and is with magic tape fixed test device, easy to adjust.
Palm one side of finger 3 contacts with three-dimensional hollow cuff 2, at the interior side bonds light emitting diode 6 and the photodiode 7 of hollow cuff 2, and about the about 9mm of air line distance of light emitting diode 6 and photodiode 7.Hold down finger after 3 when hollow cuff 2 expands, cross light emitting diode 6 and arrive about about 45 ° of central angle folded between the straight line at finger center with photodiode 7 to the straight line at finger center.For guaranteeing that peripheral vessel congestion degree is reduced to minimum, be provided with gripper shoe 4 and be fixed on the magic tape at the offside of hollow cuff 2, have only two places oppressed on the finger when making the blood pressure continuous detecting.
In the embodiment shown in Figure 2, arc substrate 1 is fixed together with glue in the inboard of arc substrate 1 with hollow cuff 2.Be bonded in the light emitting diode 6 of hollow cuff 2 inboards and photodiode 7 is connected in arc substrate 1 respectively with a flexible circuit board inboard; And join through binding post and lead in the outside of arc substrate 1, the lead-out wire of light emitting diode 6 and photodiode 7 is electrically connected with patch panel 11.Pressure transducer 8 links to each other with the inner chamber of hollow cuff 2 through the aperture of arc substrate 1, to detect the cuff pressure inside.As shown in Figure 3, the soft U type of LED circuit board 9 is made U word shape, and the soft U type of PD shown in Figure 4 circuit board 10 is made U word shape, mainly is to be convenient to can be out of shape when hollow cuff 2 expands, and light emitting diode 6 and photodiode 7 can not broken away from hollow cuff 2 inboards.Simultaneously, when hollow cuff 2 was exitted, the elasticity of the U font flexible circuit board of light emitting diode 6 and photodiode 7 can be withdrawn into the home position with hollow cuff 2.
