The specific embodiment
The present invention is based on existing non-invasive blood-sugar detecting instrument probe designs, be used to improve the accuracy and shortening interval time of measurement of blood glucose measurement.
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
As shown in Figure 1, be the structure chart of heat conducting device among the present invention, the structure of heat conducting device comprises: down contact 1, contact seat board 2, fin 3, base circuit plate 4, compression spring 5, packing ring 6, screw 7, heat conductive bar 8 down.
As shown in Figure 2, be to contact 1 structure chart among the present invention down.Under contact 1 on the middle part has contact square hole 101, be provided with in the position, next door of last contact square hole 101 and contact groove 102.
The bottom that contacts seat board 2 down is provided with four seat board fixed legs 201, is provided with the thin end 202 of contact seat board fixed leg down in seat board fixed leg 201 bottoms, and the middle part of following contact seat board 2 has down contact seat board square hole 203.Contact 1 down and be arranged on down the top that contacts seat board 2.
As shown in Figure 3, be the structure chart of base circuit plate 4 among the present invention.Base circuit plate 4 has base circuit plate circular hole 401 in four bights, has base circuit plate square hole 402 at the middle part, and the upper surface of base circuit plate 4 is the face 403 that touches on the base circuit plate.
As shown in Figure 4; Be the structure chart of heat conductive bar 8 among the present invention, heat conductive bar 8 is decussate texture on the whole, and top is heat conductive bar butt end 804; The bottom is the thin end 805 of heat conductive bar; About the upper surface of two sides be the face 801 that touches on the heat conductive bar salient point, touch on the heat conductive bar salient point face 801 with about the lower surface of two sides be the face 802 that touches under the heat conductive bar salient point, the top of heat conductive bar butt end 804 is heat conductive bar upper limb 803.
As shown in Figure 5; It is the accessory assembly drawing of heat conducting device among the present invention; Four contact the thin end 202 of seat board fixed leg down and run through fin circular hole 301, base circuit plate circular hole 401, compression spring 5 from top to down successively; Bottom at compression spring 5 is provided with packing ring 6, and packing ring 6 is fixed on the screw 7, and screw 7 is fixed on down the bottom of the thin end 202 of contact seat board fixed leg.Four compression springs 5 are enclosed within four respectively and contact down on the thin end 202 of seat board fixed leg between base circuit plate 4 and packing ring 6.
The thin end 805 of the heat conductive bar of heat conductive bar 8 passes base circuit plate square hole 402, is fixed on the base circuit plate square hole 402, touches under the heat conductive bar salient point to touch face 403 on face 802 and the base circuit plate and contact also adhesion and fix; The heat conductive bar butt end 804 of heat conductive bar 8 pass successively from the bottom up fin square hole 302, down contact seat board square hole 203 with on contact square hole 101.Heat conductive bar upper limb 803 passes contact square hole 101, and is positioned at the top of contact square hole 101.
Under contact seat board fixed leg 201,202 and combine whole heat conducting device as a whole.Wherein base circuit plate circular hole 401 is very smooth with the contact surface that contacts the thin end 202 of seat board fixed leg down, makes base circuit plate 4 abilities hold 202 to be free to slide along contact seat board fixed leg is thin down.
When heat conductive bar upper limb 803 received finger pressure, heat conductive bar 8 pressed down base circuit plate 4, and base circuit plate 4 presses down compression spring 5, base circuit plate 4 under the support of compression spring 5 along under contact the thin end 202 of seat board fixed leg and move down.
As shown in Figure 6, the state diagram of heat conducting device when being the pressure that following contact is not pointed among the present invention.The position of base circuit plate 4 and heat conductive bar 8 is the state when resetting; The pressure that this moment, heat conductive bar 8 was not pointed; Compression spring 5 is pushed into base circuit plate 4 and heat conductive bar 8 highest order of design; Touch face 802 on the heat conductive bar salient point and prop up fin 3, at this moment base circuit plate 4 and the very little gap that has that contacts seat board fixed leg butt end 201 down.State when heat conductive bar 8 receives a relatively large pressure, this moment, heat conductive bar 8 was in lowest order, compression spring 4 elastic deformations reach maximum, base circuit plate 4 with time contact the maximum that distance between the seat board fixed leg butt end 201 reaches design.
As shown in Figure 7, be the structure chart of popping one's head among the present invention.The structure of probe comprises: heat conducting device, base 9, torsionspring 10, cover plate 11, base 9 and cover plate 11 are connected through hinge, and torsionspring 10 is fixed between base 9 and the cover plate 11, and heat conducting device is placed in the base 9.
Below in conjunction with structure of the present invention, use is described in detail.
When the probe that has a heat conducting device when use is measured the patient; At first open probe mount 9 and cover plate 11, place the finger groove of contact 1 to tested finger, the finger nature keeps flat; Finger tip props up down contact groove 102, and this moment, the finger tip abdominal part can touch heat conductive bar upper limb 803.Close up base 9 and cover plate 11 then, under the effect of torsionspring 10,11 of base 9 and cover plates apply a pressure to finger.This pressure passes to heat conductive bar 8 through finger, and the base circuit plate 4 of 8 drives of heat conductive bar holds 202 under the support of compression spring 5, to move down along contact seat board fixed leg is thin down; When measurement finishes when removing the pressure of finger, 5 on compression spring promotes base circuit plate 4 and drives heat conductive bars 8 and move up until resetting.Through the regulating action of 5 pairs of pressure of compression spring, finger remains in the suitable scope the pressure of heat conductive bar 8 in measuring process, has effectively avoided because the measurement error that the finger size difference causes.
After using probe to accomplish one-shot measurement, finger shifts out probe, and when this moment, heat conductive bar 8 did not receive finger pressure to be in reset mode, contact surface 801 closely contacted with fin 3 on the heat conductive bar salient point, and heat can conduct to the fin 3 from heat conductive bar 8 under this state.
