The specific embodiment
Basic conception of the present invention is: utilize the research of existing transudate color and pathology sense corresponding relation, increase the online measuring ability of transudate color at existing negative pressure treatment equipment, obtained color signal or the visual signal of transudate by the color acquisition system, the color detection control unit calculates corresponding color according to color signal or visual signal, offer in real time alarm device, or study for medical personnel after the storage.
Below in conjunction with accompanying drawing, by specific embodiment negative pressure wound treating system of the present invention is elaborated.
Embodiment one
Referring to Fig. 2, be the negative pressure wound treating system that detects the transudate color of the present invention, comprise the parts such as liquid-collecting bottle 5, negative pressure wound therapy device 8, wound external member and color acquisition system 9, color detection control unit, wherein:
Liquid-collecting bottle 5 is used for collecting wound fluid;
Negative pressure wound therapy device 8 is comprised of negative pressure source 6 and controller 7;
The wound external member be used for to be filled and wound closure 1,---wound dressing 2, the wound closure---pad pasting 3 that comprises the wound implant, and wound dressing 2 wherein is communicated with liquid-collecting bottle 5 by connection tube 4;
Color acquisition system 9 is arranged on the connection tube 4, obtains to flow through wound fluid or the color signal of secretions---the rgb value that connection tube 4 extracts; Certainly, also can obtain the visual signal of transudate.
Color detection control unit (scheming not shown) is arranged in the controller 7, and the color signal of the transudate that obtains and/or visual signal calculate the corresponding color of transudate.The colouring information of these transudates offers alarm device in real time, in order to be in time to take measures having an accident; Simultaneously, they also are stored in the memory element, in order to further study for medical personnel.
Color acquisition system 9 as shown in Figure 3, inner in its optical system: the light from point source 91 (xenon lamp) forms directional light by parabolic mirror 92; Directional light passes a diffusion sheet 93 that is made of translucent polyethylene, makes light become evenly soft; Light forms diffuse-reflectance through diffuse reflector 94 and enters color sensor light chamber 95; Dispersed and distributed trichromatic color sensor 96 in light chamber bottom is so that qualitative and/or obtain quantitatively the three primary colors that color sensor light chamber 95 receives light; For guarantee light can uniform irradiation on three primary colors color sensor 96, another piece diffusion sheet 97 and an IR filter 98 have been installed in the light chamber, be evenly distributed on the different color sensor 96 to guarantee light.
Especially, the 95 inner all level dyeing of color sensor light chamber are black and airtight, to guarantee the close property of its light, avoid arranging at color sensor 96 generation of end light leakage phenomena.Avoid to greatest extent thus inner light reflection, light at utmost is radiated on the color sensor 96 after by the aperture with little angle of scattering.
Another important component part of color sensor 96 optical systems is fin 910, is made of irregularly shaped aluminium flake.This fin 910 is placed in the optical system of color sensor 96, can be used to the element radiatings such as commutator in reflecting mirror and the light source place circuit.
Most color all can be combined in varing proportions by R, G, B three primary colors, and the trichroism wavelength of three primary colors red, green, blue is different, and frequency is different.Three primary colors color sensor 96 receives the separately color of frequency, and the value of its change in voltage is also different, thereby can calculate the shared ratio of three primary colors according to the magnitude of voltage that receives three primary colors, finally derives the color of transudate.
The transudate corresponding color of obtaining can offer the alarm signal generation unit that arranges in the controller, in order to the transudate corresponding color that obtains is contrasted with the corresponding table of color-alarm signal of presetting, generates corresponding alarm signal.
In the above-mentioned negative pressure wound treating system that detects the transudate color, the alarm signal generation unit is set further in the controller 7, the transudate corresponding color that obtains can be contrasted with the corresponding table of color-alarm signal of presetting, generate corresponding alarm signal.Therefore, this system can detect online to the color of transudate, in time sends corresponding alarm signal, and caution medical personnel or patient are so that medical personnel can in time do Prevention Processing before the accident that may lead to grave consequences; Simultaneously, medical personnel also can according to the wound information that comprises at least colouring information of storing in the memory element, carry out more deep research.
The using method of the negative pressure wound treating system of the detected transudate color of present embodiment is: when the treatment wound, fill wound dressing 2 at wound 1 place, connection tube 4 is inserted in the wound dressing, the above seals with pad pasting 3,4 places arrange Color Detecting System 9 at connection tube, and this Color Detecting System 9 comprises color sensor.When negative pressure source 6 work, the transudate that extracts from wound 1 or secretions are by way of the Color Detecting System 9 at connection tube 4 places the time, Color Detecting System 9 gathers the color signal-rgb value of transudate or secretions, and be sent in the controller 7, the color detection control unit in the controller 7 calculates the color of this transudate or secretions.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with the determined scope of claim.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
