According to the finger clamp type blood oxygen probe, improvement is conducted on the basis of a traditional blood oxygen probe, as the measuring baffle is added to the probe, the fact that the measuring optical elements accurately light nails is guaranteed, interference produced by movement of fingers can be reduced well, cost is low, use is convenient, and the finger clamp type blood oxygen probe can be widely applied in the market.
Description
Technical field
This utility model relates to blood oxygen probe field, particularly a kind of finger clip type blood oxygen probe.
Background technology
Studies show that HbO2 Oxyhemoglobin and deoxyhemoglobin have different absorbances to the different wave length incident illumination.When a certain position of the fixing irradiation finger of monochromatic light, arterial blood changes with the transparent area arteriopalmus the Optical Absorption rate, and the tissue such as skin, muscle, skeleton and vein is invariable to Optical Absorption.
Existing finger clip type blood oxygen probe is after finger stretches into blood oxygen probe, because can't see light emitting diode and finger, so accurately the positioning luminous diode shines the position at fingernail place.When finger stretched into when shallow, cause diode to be radiated at the finger fingertip position, the tissue area that is subject to illumination is too small, obtains the pulse useful information not enough.And that finger stretched into was dark, causing probe to be radiated at bone tissue place, and the bone light transmission is poor, can not obtain useful arterial pulse wave information.Simultaneously point in use and move before and after having due to user, the logical light path when causing the probe irradiation changes, thereby produces motion artifacts, has affected the accuracy of Oximetry.
The present invention is directed to the problems referred to above, improve on the basis of traditional blood oxygen probe, point irradiation position by the location, make light emitting diode can accurately shine fingernail, when obtaining better pulse wave, can reduce again the interference that finger motion produces, and with low cost, easy to use, can be widely used in market.
The utility model content
For solving the problems of the technologies described above, this utility model provides a kind of finger clip type blood oxygen probe, comprising: form the U-shaped cavity upper clamping part, lower clamping part, be arranged at data wire in described one clamping part, be arranged at the measurement optical element on described upper clamping part, lower clamping part and measure baffle plate respectively.Described measurement baffle plate is arranged on the closing end of described U-shaped cavity and measures between optical element.
Preferably, described measurement optical element comprises the light emitting diode of transmitting terminal and light-to-frequency converter or the phototriode of receiving terminal.
Preferably, the distance between described measurement baffle plate and described light emitting diode is regulated by two gears.
Preferably, the first span between described measurement baffle plate and described light emitting diode is from being 0.2-0.6cm.
Preferably, the distance of the second gear between described measurement baffle plate and described light emitting diode is 0.4-2cm.
Preferably, described measurement baffle plate is fixed on the upper clamping part or lower clamping part at the described light emitting diode 0.4-0.6cm of distance place.
Preferably, described measurement baffle plate is shaped as rectangle, cylinder, grid, little fence or irregular figure.
Useful technique effect of the present utility model is: fingernail can be accurately shone by finger locating being guaranteed light emitting diode, the interference that finger motion produces can be reduced preferably, and with low cost, easy to use, can be widely used in market.
Description of drawings

Fig. 2 is the structural representation of finger clip type blood oxygen probe user mode in this utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, be the structural representation of finger clip type blood oxygen probe in this utility model.
Described finger clip type blood oxygen probe comprises: form the U-shaped cavity upper clamping part 2, lower clamping part 6, control upper and lower clamping part openings of sizes probe afterbody 3 and 8, be arranged at data wire 1 in clamping part 2 or lower clamping part 6, the measurement baffle plate 5 between the closing end that is arranged at the measurement optical element on described upper clamping part 2, lower clamping part 6 and is arranged on described U-shaped cavity respectively and measurement optical element.Described measurement optical element comprises the light emitting diode 4 of transmitting terminal and light-to-frequency converter or the phototriode 7 of receiving terminal.
This utility model is mainly to improve on the basis of traditional blood oxygen probe.That is, arrange one at upper clamping part 2 or lower clamping part 6 and measure baffle plate 5, this measurements baffle plate 5 has a bit of distance apart from light emitting diode 4, for the length that auxiliary positioning enters the finger of cavity, makes light emitting diode 4 can accurately be radiated at the fingernail place.
The size of this distance can be regulated according to the situation of user, and two gears are set herein usually.Wherein, first grade more is applicable to child, and the distance of measuring between baffle plate 5 and described light emitting diode 4 is 0.2-0.6cm.Second gear more is applicable to the adult, and the distance of measuring between baffle plate 5 and described light emitting diode 4 is 0.4-2cm.
The regulative mode of gear is not limit.For example the design by structure adopts piece-picking type to regulate, on the one clamping part near first grade of the blood oxygen probe cavity arranged outside plectrum with second gear; By the mode of electrical adjustment, be perhaps child or adult according to user, input corresponding gear by the doctor, adjusted by structure corresponding in clamping part.
Consider simplicity of design, also can adopt the total distance between first grade and second gear, for example will measure baffle plate 5 apart from the distance of light emitting diode 4 in the somewhere between 0.4-0.6cm and be fixed on clamping part 2 or time clamping part 6.Through such improvement, when finger 9 stretches into (as Fig. 2), only need finger tips to touch and measure baffle plate 5, light emitting diode 4 in probe can be radiated at the middle part of fingernail more accurately, the signal that just can guarantee to gather is when comprising necessary human body information, amplitude is of moderate size, neither can be too low too high only.
In the present embodiment, the shape of measurement baffle plate 5 can be for rectangle, cylinder, grid or little fence etc., as long as can effectively play barrier effect.
Need to prove, each technical characterictic listed above, it mutually makes up and can form each embodiment, and each embodiment listed above, it makes up formation mutually without each embodiment that describes in detail, should be regarded as belonging to the scope of this utility model description record.And the above is only of the present utility model better feasible, and unrestricted protection domain of the present utility model, and the equivalent structure that all utilization this utility model description and accompanying drawing content have been done changes, and all is included in protection domain of the present utility model.
