The specific embodiment
Below in conjunction with accompanying drawing, the negative pressure wound treating system that detects the transudate transparency of the present utility model is elaborated by specific embodiment.
Embodiment one
Referring to Fig. 2 and Fig. 3, Fig. 2 is the structural representation of the negative pressure wound treating system of the detected transudate transparency in the present embodiment, and Fig. 3 is the light path sketch map at A place among Fig. 2.
The negative pressure wound treating system of the detected transudate transparency in the present embodiment comprises:
Liquid-collecting bottle 5 is used to collect wound fluid;
Negative pressure wound therapy equipment 8 comprises negative pressure source 6 and controller 7;
The wound external member is used to fill wound and wound closure, comprises wound implant 2, wound closure 3, and wound implant 2 is communicated with liquid-collecting bottle 5 by connection tube 4;
On the sidewall of liquid-collecting bottle 5, longitudinally also be provided with four wound fluid transparency detection modules 9 at interval in the same manner;
Wherein, display unit is the LED display interface.Certainly, also can select other display interfaces for use, as the LCD interface.
Wherein, each wound fluid transudate volume detection module 9 comprises:
Receiving element 92 receives through liquid-collecting bottle 5 refractive electromagnetic wave signals, relatively is arranged on the opposite side of liquid-collecting bottle 5 with transmitter unit 91.
Detect control unit, the size that electromagnetic wave that receives according to receiving element or ultrasonic signal size are judged the wound fluid transparency.Be specially: the correspondence table that preestablishes the value of a wound fluid transparency and the electromagnetism wave number that receiving element receives, in this table, the corresponding transparency maximum 100 of the electromagnetic wave signal maximum that receives, the minima 0 of the corresponding transparency of the electromagnetic wave signal minima that receives, in 0～100 scope, each numerical value is all corresponding with an electromagnetic wave signal value, and therefore, the electromagnetic wave signal value that receives according to receiving element can be searched and be obtained corresponding wound fluid transparence value.Between receiving element and transmitter unit during no transudate, the electromagnetic wave signal maximum of receiving element, this moment, the value of corresponding transparency was a maximum, the electromagnetic wave signal that receiving element receives is during less than maximum, then meaning between transmitter unit and the receiving element has transudate, and signal value is more little, and transparency is low more, when not receiving signal fully, the transparency minimum.Certainly the transparency size also can be corresponding one by one by the height of gear with the size of electromagnetic wave signal, is divided into 2,3,4,5,6 etc. grades such as the size with transparency, the corresponding gear of each gear correspondence electromagnetic wave signal value.

Wherein, receiving element 92 according to four wound fluid transparency detection modules 9 that vertically are provided with along liquid-collecting bottle receives the infrared signal size, can judge the size of the interior relevant position of the liquid-collecting bottle transudate transparency of each wound fluid transparency detection module 9 present position correspondence, because it is inconsistent with the wound penetrating fluid transparency that is in the below to be in the transparency of the wound fluid above the liquid-collecting bottle, therefore, the corresponding wound fluid transparency size of size of the infrared signal that receives by each receiving element 92, calculate meansigma methods, as the transparence value of current wound fluid.
Embodiment two
The difference of present embodiment and embodiment one is:
A wound fluid transparency detection module 9 only is set, transmitter unit and receiving element collection are located at together, referring to Fig. 6, wound fluid volume detection module 9 is enclosed within on the vertical screw mandrel 10 that extends of a centrage, and screw mandrel 10 centrages are parallel with liquid-collecting bottle 5 above-below directions; Preferably, wound fluid transparency detection module 9 is suffered restraints on screw mandrel 10 centrage circumferential direction, only can on screw mandrel 10 centerline directions, move; One end of screw mandrel 10 is connected with motor 11, under the driving of motor 11, screw mandrel 10 is around its centrage rotation, thereby driving wound fluid transparency module 9 moves up and down along screw mandrel 10 centrages, the electromagnetic wave signal size that liquid-collecting bottle 5 relevant positions are received detects, and then measures wound transparency size.
Wherein, screw mandrel 10 also can be substituted as in: gear train, belt, the skin wheel any by other drive mechanisms; As long as wound fluid transparency detection module 9 can moved at longitudinal direction with respect to liquid-collecting bottle 5, just can realize detecting the purpose of liquid-collecting bottle 5 relevant position transparencys.
When motor 11 work, driving wound fluid transparency detection module 9 by screw mandrel 10 moves up and down, controller 7 can calculate the transparency of differing heights place wound fluid in the liquid-collecting bottle 5 according to the stroke of motor, thereby calculates the average transparency of wound fluid in the liquid-collecting bottle 5.
Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with the determined scope of claim.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
