Description
Technical field
This utility model relates to field of medical device, in particular it relates to one refers to press from both sides BOLD contrast.
Background technology
Existing finger folder BOLD contrast the most all includes upper shell, lower house and measuring circuit plate, together with upper shell is pivotally connected with lower house, upper shell and lower house can rotate around a common pivot under wind spring effect with mutually drawing close, to clamp measured finger, thus carry out the measurement of blood oxygen saturation.
Additionally, in order to increase the finger measured comfort level, adapt to different thicknesses, existing blood oxygen measuring device typically uses and arranges, at upper-lower casing opposite face, the silicagel pad that shape therewith is identical, and, in order to the finger locating preventing user is inaccurate or unconsciously makes finger be moved during measuring, the accuracy that impact is measured, existing blood oxygen measuring device uses the mode arranging raised points, raised item in silicagel pad, prompting user to place a finger on position accurately and measure.This mode adds assembly difficulty and adds production cost.
Summary of the invention
This utility model is in order to overcome above-mentioned deficiency of the prior art, it is provided that following technical scheme:
One refers to press from both sides BOLD contrast, including upper shell, lower house and measuring circuit plate, described measuring circuit plate is arranged in described upper shell, together with described upper shell is pivotally connected with lower house, the opposite face of described upper shell and lower house is respectively arranged with measurement luminous tube and light receiving tube, described opposite face forms finger cavity, and the upper surface of described lower house is provided with the projection of the finger tripe supporting measured finger.
Wherein, the lower surface of upper shell is provided with the projection of the finger tripe supporting measured finger.
Wherein, described projection cross section in the horizontal direction be shaped as U-shaped, the opening of described projection is towards the Way in of described finger cavity, and the blind end of described projection is towards the direction of described pivot, and around described measurement luminous tube or light receiving tube.
Wherein, the longitudinal centre line of described projection overlaps with the longitudinal centre line of described lower house.
Wherein, described projection cross section semicircular in shape vertically or polygon.
Wherein, the smallest lateral dimension in described projection cross section vertically is between 0.5-2mm.
Wherein, the maximum height in protruding cross section vertically is between 0.3-2.0mm.
Wherein, the inner width width of bump openings end is between 5-15mm.
Wherein, described projection near the height of the part of pivot more than the height of part away from pivot.
Wherein, described projection is continuous distribution or discontinuously arranged.

Detailed description of the invention
For making those skilled in the art be more fully understood that the technical solution of the utility model, the finger folder BOLD contrast embodiment provided this utility model below in conjunction with the accompanying drawings is described in detail.
Refer to Fig. 1 to Fig. 3, the finger folder BOLD contrast of this utility model first embodiment, including upper shell 1, lower house 2 and measuring circuit plate (not shown), measuring circuit plate is arranged in described upper shell 1, upper shell 1 and lower house 2 connect 3 by pivot and are connected together, the opposite face of upper shell 1 and lower house 2 is respectively arranged with measurement luminous tube (not shown) and light receiving tube 5, described opposite face forms finger cavity, and the upper surface of lower house 2 is provided with the projection 4 of the finger tripe supporting measured finger.
Equally, it is also possible to being provided with the projection of the finger tripe supporting measured finger on the lower surface of upper shell 1, its principle is identical with aforesaid way, no longer describes in detail at this.
Such as Fig. 3, described protruding 4 cross sections in the horizontal direction be shaped as U-shaped, the described opening of protruding 4 41 is towards the Way in of finger cavity, i.e. away from the direction of pivot 3；The described blind end of protruding 4 42 is towards the direction of pivot 3, and around described light receiving tube 5.
Accordingly, if the lower surface at upper shell 1 arranges protruding 4, then the blind end 42 of protruding 4 is around the measurement luminous tube corresponding with light receiving tube 5 being arranged on upper shell.
Such as Fig. 1, the protruding longitudinal centre line of 4 overlaps with the longitudinal centre line of described lower house 2.
Such as Fig. 2, protruding 4 cross section semicirculars in shape vertically, square or polygon, or other desired shape, its shape can make different selections according to practical situation.
The smallest lateral dimension in protruding 4 cross sections vertically is between 0.5-2mm, and preferred size is 1.5mm；The maximum height in protruding 4 cross sections vertically is between 0.3-2.0mm, and preferably height is 1.5mm.
The inner width width of protruding 4 openings is between 5-15mm, and preferable width is 12mm.Preferably, in the present embodiment, protruding 4 near the height of the part of pivot 3 more than the height of the part away from pivot 3, the shape of finger finger tip of so can preferably fitting.
The finger folder BOLD contrast of the present embodiment, by arranging projection at the upper surface of lower house 2, supports tested finger tripe, it is ensured that in finger, blood flowing is not by referring to that clamping force is affected, and concurrently forms the structure of finger locating, improves accuracy of measurement and comfortableness.Use projection to substitute existing silicagel pad, product can be made to be easy to assembling, maintenance, and reduce production cost.
Fig. 4 is the bulge-structure schematic diagram referring to folder BOLD contrast of this utility model the second embodiment.The present embodiment is with the difference of first embodiment, and what the present embodiment provided refers to that the projection of folder BOLD contrast is discontinuously arranged.Concrete, it is the shape being become a U-shaped by multiple bump array.The finger folder BOLD contrast of the present embodiment, by arranging discontinuous projection at lower house upper surface, supports tested finger tripe, it is ensured that in finger, blood flowing is not by referring to that clamping force is affected, and concurrently forms the structure of finger locating, improves accuracy of measurement and comfortableness.Use projection to substitute existing silicagel pad, product can be made to be easy to assembling, maintenance, and production cost can be reduced further.
As deformation, finger of the present utility model folder BOLD contrast, its projection can be to be one or dismountable with upper shell or lower house, and what the material of the housing of protruding and its connection can be identical can also be different.
It is understood that embodiment of above is merely to illustrate that principle of the present utility model and the illustrative embodiments that uses, but this utility model is not limited thereto.For those skilled in the art, in the case of without departing from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
