The specific embodiment
Below in conjunction with accompanying drawing, the negative pressure wound treating system that detects the transudate transparency of the present invention is elaborated through concrete 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 thing 3, and wound implant 2 is communicated with liquid-collecting bottle 5 through 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 identically;
Wherein, display unit is the LED display interface.Certainly, also can select other display interfaces for use, like 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 corresponding tables 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 obtained corresponding wound fluid transparence value.During no transudate, the electromagnetic wave signal of receiving element is maximum between receiving element and transmitter unit, and 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, transparency is minimum.Certainly the transparency size also can be corresponding one by one through 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, the electromagnetic wave that adopts in the present embodiment is an infrared ray, as other embodiment, also can adopt visible light, ultraviolet, laser or other electromagnetic signals, can adopt ultrasound wave, infrasonic wave or other acoustic signals.
Referring to Fig. 3; Transmitter unit 91 sends infrared ray S1; Penetrate refraction through liquid-collecting bottle sidewall 51 1 sides and get into liquid-collecting bottle interior zone 52; And then from the ejaculation of liquid-collecting bottle sidewall 51 opposite sides, receiving element 92 receives and penetrates the infrared ray S1 that refraction is come, and another part IR is through being reflected into reflection ray S2.
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 relevant position transudate transparency in the corresponding liquid-collecting bottle in each wound fluid transparency detection module 9 present position; Because it is inconsistent with the wound penetrating fluid transparency that is in the below to be in the transparency of wound fluid of liquid-collecting bottle top, therefore, the corresponding wound fluid transparency size of size of the infrared signal that receives through 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 transparency 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; Move up and down along screw mandrel 10 centrages thereby drive wound fluid transparency module 9, 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 like 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 through 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 invention below, should be pointed out that above-mentioned preferred implementation should not be regarded as limitation of the present invention, protection scope of the present invention should be as the criterion with the determined scope of claim.For the technical staff in present technique field, do not breaking away from the spirit and scope of the present invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
