A kind of blood oxygen sampled by light-guiding pillar gathers sensing deviceTechnical field
The present invention relates to medical treatment electronic equipment, gather sensing device particularly to a kind of blood oxygen sampled by light-guiding pillar.
Background technology
Along with popularizing of wearable device, increasing detection and monitoring equipment are applied.Such as detecting or monitor the finger-clipped of oximetry data, finger ring type BOLD contrast or the wearable device such as blood oxygen harvester or wrist-watch, bracelet, foot ring, medicated cap, clothes.The sensing station of current signals collecting is all be close to collection position to place, distinct device is different to the placement location of blood oxygen transducer, this just requires need to by the sensor design diverse location at monitoring equipment when design, but the collection point of difference wearable device is not necessarily suitable for placing blood oxygen transducer, which limits wearable device development.
Summary of the invention
The purpose of the present invention is to propose to a kind of blood oxygen sampled by light-guiding pillar and gather sensing device, by a light pipe, transducing signal is extended, it is achieved blood oxygen gathers the multipurpose function of sensing device.
To achieve these goals, the technical scheme is that a kind of blood oxygen sampled by light-guiding pillar gathers sensing device, including the sensor being connected with blood oxygen acquisition process circuit and wearable device, described sensor has a luminous tube and a reception pipe, wherein, described luminous tube and reception pipe are connected with the blood oxygen acquisition port of wearable device respectively through luminous light pipe and reception light pipe.
Scheme is further: described luminous light pipe and to receive light pipe be optical fiber tube.
Scheme is further: described optical fiber tube is outer surface is the lighttight optical fiber tube of black, and the medium in optical fiber tube is the one in glass, PVC, PMMA.
Scheme is further: described wearable device is the one in bracelet, foot ring, wrist-watch, ring, glove, medicated cap.
Scheme is further: described blood oxygen acquisition port is in a plane of wearable device, or not in one plane.
Scheme is further: described luminous light pipe and receive the length of light pipe and be not more than the length that light loss permissible value requires.
The invention has the beneficial effects as follows:
Light is directed to the convenient position easily measuring blood oxygen by light pipe by the sensor of blood oxygen equipment by the present invention, so can avoid using wire harness to connect sensor in the place not easily laid, reduce process costs, be also convenient for assembling.
The present invention can specially arrange luminous tube, receive the position of pipe, therefore, sensor can be positioned over the optional position of equipment, and this be that the multiplexing of luminous tube provides conveniently, luminous tube can be used as the multiplexing of other functions of instruction, thus reducing the cost of equipment.
Below in conjunction with drawings and Examples, the present invention is described in detail.

Detailed description of the invention
A kind of blood oxygen sampled by light-guiding pillar gathers sensing device, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, including the sensor being connected with blood oxygen acquisition process circuit and wearable device 1, blood oxygen acquisition process circuit is arranged in wearable device, described sensor has a luminous tube 2 and a reception pipe 3, wherein, described luminous tube and reception pipe are connected with the blood oxygen acquisition port of wearable device respectively through luminous light pipe 4 and reception light pipe 5, and blood oxygen acquisition port includes the acquisition port 6 being connected with luminous light pipe 4 and the acquisition port 7 being connected with reception light pipe 5；This structure can arrange blood oxygen acquisition process circuit and sensor flexibly, the blood oxygen transducer setting broken traditions, light is directed to conveniently by light-guiding pillar medium, easily measures the position of blood oxygen, not only reduce the difficulty that technique manufactures, and luminous tube can also do multiplexing functions, used by the display lamp of other functions, the injection forming mold of design wearable device housing, sensor and light pipe, after once having designed, so that it may use, facilitate the design of wearable device always.
In embodiment: the selection of light pipe material is extremely important, luminous light pipe described in the present embodiment and reception light pipe are optical fiber tubes；For making light reduce the interference of external environment and the loss in Medium Propagation process in the process guided, the present invention have chosen solid casting skin optical fiber, crust is wrapped up by the epidermis of black, the internal substantial glass of uniform dielectric, PVC, PMMA material, it may be assumed that described optical fiber tube is outer surface is the lighttight optical fiber tube of black.
In embodiment: described wearable device is the one in bracelet, foot ring, wrist-watch, ring, glove, medicated cap, described blood oxygen acquisition port is in a plane of wearable device, or not in one plane.Fig. 5 illustrates the application in ring, because the blood vessel in finger belly is relatively more, and band ring in finger belly, luminous tube and reception pipe need to be directed to the blood oxygen acquisition port 6 and 7 of the both sides of finger belly, between the angle of blood oxygen acquisition port is spent at 30 degree-90,60 degree are best.Fig. 6 illustrates the application at bracelet or wrist-watch: blood oxygen acquisition port 6 and 7 is arranged at the place below ulna near upper arm, solves, by light-conductive optic fibre, the aging loose contact problem that wire harness causes due to bending.Fig. 7 illustrates application on medicated cap: blood oxygen acquisition port 6 and 7 is arranged at the supraorbital artery place on forehead eye socket top；The top of medicated cap uses VELCRO to be fixed by blood oxygen acquisition process circuit.
In embodiment: the length of described luminous light pipe and reception light pipe is not more than the length that light loss permissible value requires.Light must be lossy in antivacuum propagation, if loss is too much, cannot reach accurately to measure the effect of blood oxygen.This choosing of derivation tube material will meet certain requirement with its length.
First bigger loss is owing to length loss causes, it is known that the input power of HONGGUANG and infrared light、, and accurately to measure the Output optical power needed for blood oxygen、, and the proportion of goods damageds that light is in media as wellAccording to formula, secondly consider docking loss and the bending loss of optical fiber, the greatest length of light-conductive optic fibre can be calculated；Wherein: Pin and Pout respectively inputs and Output optical power.
