Abstract
The utility model belongs to a medical sensor is a pulse wave sensor with get pulse position and instruct, and characterized by has the pressure probe that has the cantilever beam structure three or more than three, and the position of sensor contact skin is a platform, and each pressure probe's terminal surface all is located the plane of this platform, and the effect of platform is a flat position with subcutaneous surveyed arterial wall extrusion. Because the sensor is provided with a plurality of probes, the width of each probe is equal to or less than 1 mm, each probe can give subcutaneous pressure change, and the probe at the middle part is easy to align at the middle part of the artery wall. The simpler one is a pulse wave sensor with three probes, the middle probe is used for measuring blood pressure waves, and the probes on the two sides have the function of taking pulse position indication.
Description
This utility model belongs to medical energy converter, is a kind of many probes pulse sensor of getting the indication of arteries and veins position that has, and can be used for percutaneous blood pressure ripple and measures.
At present, in the mensuration of pulse wave, generally use the bigger pressure pulse sensor of probe area, though this pulse sensor energy measurement pulse wave, but do not have good linear relationship between this pulse wave and the blood pressure value, this is because under the pressure probe end area situation more much bigger than tremulous pulse caliber, ductus arteriosus wall with pop one's head between the pressure transmission area in continuous change.If reduce the area of pressure probe, then be difficult to seek and judge whether sensor probe is placed on the tram.If sensor probe is not placed into the central part of tested arterial wall, the pulse wave of gained and blood pressure waveform all have bigger difference on amplitude, form.Utilize this pulse wave to carry out hemodynamic result calculated and often have big error.
Whether correct the purpose of this utility model provides a kind of many probe pulse sensors, and each probe all has independently cantilever beam type pressure measurement structure, and the pick off overall structure meets blood pressure ripple measuring principle, and can provide sensor determination position criterion easily.
For achieving the above object, the pulse sensor of this utility model design, there are one 0.4 square centimeter or bigger platform in position at contact skin, the pressure probe that an area 0.5-2 square millimeter is arranged in the middle part of this platform, when this probe is positioned at tested ductus arteriosus wall and has been pressed into the middle part at smooth position by platform, can measure blood pressure waveform well.Whether correct increase pressure probe quantity and reasonable disposition probe on this basis according to pulse wave form and the amplitude that pressure probe is measured, can provide and get the indication of arteries and veins position.
Solution of the present utility model can be further with following embodiment explanation.
A kind of configuration mode such as Fig. 1 of sensor probe, at the middle part of platform plane P one rectangular opening is arranged, dispose the rectangle probe of two millimeters of a, b, three wide millimeters long of c in the rectangular opening, the plane of all probe end all is in same plane with plane P, a, b, three probes of c are arranged in a straight line, a, c probe lays respectively at two sides of b, and the gap between adjacent probe is the 0.1-0.2 millimeter.Each probe all has a cantilever beam type pressure measurement structure that structure is identical, sensitivity is close, makes the measurement sensitivity unanimity of each probe by the gain of regulating each probe amplifier.When measuring pulse wave, plane P extrudes a flat part with the shallow table tremulous pulse under the skin, regulate the pick off placement location, make probe a, c be positioned at tested tremulous pulse two sides, if the probe pulse wave signal amplitude that a, c obtained is substantially the same, the expression measuring probe is positioned at the middle part of tested tremulous pulse, gets the arteries and veins correct position, if the pulse wave amplitude that a, c two probes are obtained differs bigger, illustrating needs to continue to adjust to get the arteries and veins position.
Another kind of configuration mode such as Fig. 2 of sensor probe adopt the probe of circular end surface, and the center of circle of the end face of three probe A, B, C is positioned at three summits of an isosceles triangle.If need in the width of 3 millimeter, dispose three pressure probes with cantilever beam structures, when adopting the rectangular cantilever beam of triangle cantilever beam or broad, the structure of Fig. 1 has certain difficulty in design and processing, adopt probe configuration mode shown in Figure 2 can solve this difficulty.Adopt an embodiment of this scheme to be, sensor outer housing is rounded, there is an outwards outstanding platform at the shell middle part, the end face of platform is equal with the pressure probe end face, the height of platform plane S is 4 millimeters, and length is 10 millimeters, and wide is 8 millimeters, distance between A, the C two probe end face centers of circle is 3 millimeters, and the probe B end face center of circle is 3 millimeters to the distance of line between A, the C probe end face center of circle.The diameter of each pressure probe is 1 millimeter, is suspended in diameter on the S plane respectively and is in 1.2 millimeters the hole, and each probe all has the pressure measurement structure of cantilever beam type separately.
In order to measure the distribution of blood pressure ripple or mensuration pulse wave more easily, pick off can have the probe more than three.The pick off of five pressure probes for example, five probes are a straight line to be arranged, or the mutual cross arrangements of five probes become two row (Fig. 3).
The pick off of this utility model design not only can be used as pulse wave measuring, and is applicable to the blood pressure ripple mensuration of shallow table tremulous pulsies such as carotid artery, radial artery.
