Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of recessing tool that is used for the blood of human body sampling.
Background technology
When the doctor did the blood of human body sampling, routine techniques had two kinds.Using maximum is to draw blood behind patient's finger skin and make sample with being needled into.Another kind of adopt single-edge blade to point facing to the patient to make manual otch and draw blood sample, above-mentioned two kinds of traditional operation methods are easy, practical, can implement fast.But all there is a common drawback in existing two kinds of technology, and promptly the manually-operated poor accuracy can not accomplish that every routine depth selection is identical, and the diversity of particularly different doctor's operations is bigger.Because there is above-mentioned shortcoming in prior art, can not accomplish that all samplings all draw blood under same prescribed depth, so the diversity of taking a sample is bigger, must influence the accuracy of testing result.
The utility model content
This utility model is primarily aimed at the deficiencies in the prior art, a kind of simple in structure, processing ease is proposed, impose a condition do down fast, the quantitative medical miniature recessing tool of otch, guarantee that every example all draws blood sample under same depth, to improve the accuracy that detects.
This utility model is achieved through the following technical solutions technical goal.
The medical miniature recessing tool, it comprises switch, plug-in unit, housing, cutterhead, torque spring and cutter hub.Described housing be about two rectangular box that are harmonious and are formed by connecting, its upper left corner leaving certain gaps uncovered by the economic plan, bottom surface middle part length direction is provided with open slot.Spacer pin down is positioned at sheet end face middle part, a housing left side, and the reclinate arc groove of housing left side sheet middle inside boss is a track, and it is the pivot pin and the annulus at center that the right sheet inside bottom of housing is provided with the arc groove center of circle.Its improvements are: described housing upper left corner indentation, there is installed the drawer type switch, and spacer pin stretches in the switch end face open slot and constitutes position limiting structure.Described cutterhead left side setting-in cutter hub is installed to housing left and right sides chip bonding portion, oval tabular cutterhead small end up, the big end down, the arc groove matched in clearance on the small end left side on the sheet of the guide finger of an evagination and housing left side, large end face is provided with cannelure and cooperates formation location swinging structure with pivot pin.Described torque spring is sleeved on the annulus outer wall, and an end is made power in the right sheet of housing base, and an end roof pressure of pretension constitutes structure to be revolved on limit, cutterhead big end left side.Described plug-in unit is a kind of movable part, is inserted into switch and the vertical junction of breach, the housing upper left corner, and switch withstands cutterhead and constitutes safety structure.After taking out plug-in unit, the pull switch initial stage makes cutterhead dextrorotation to the right, and when switch missed cutterhead, it is left-handed that cutterhead drives cutter hub under the effect of torque spring, and the cutter hub point exposes open slot 0.9mm～1.1mm when being threaded to the middle position.
In the said structure, cutterhead small end left lateral is provided with open slot, and the right-hand member of switch is top to cooperate spacing cutterhead with open slot.Cutter hub is the single face cutter, and its blade is towards the right side.
This utility model compared with prior art has following good effect:
1, quantitative otch does not have artificial operate miss, and sampling is consistent;
2, quick otch, it is small to accept sampling person's misery;
3, simple and reasonable for structure, easy to manufacture.

The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Medical miniature recessing tool shown in the drawings, it comprises switch 1, plug-in unit 2, housing 3, cutterhead 4, torque spring 5 and cutter hub 6.Described housing 3 is a basic component, is a kind of rectangular box, by about two be harmonious and be formed by connecting.Housing 3 upper left corner leaving certain gaps uncovered by the economic plans, middle part, bottom surface length direction is provided with open slot 3.3, spacer pin 3.1 down is located at sheet end face middle part, a housing left side, the reclinate arc groove 3.2 of housing left side sheet middle inside boss is a track, and it is the pivot pin 3.4 and the annulus 3.5 at center that right sheet inside bottom is provided with arc groove 3.2 centers of circle.But described switch 1 is installed in housing 3 left upper move left and right, and spacer pin 3.1 stretches in the switch 1 end face open slot and constitutes position limiting structure.Cutterhead 4 left side setting-in cutter hubs 6 are installed to housing 3 left and right sides chip bonding portions, and oval tabular cutterhead 4 small ends are held down greatly up, the guide finger 4.1 of evagination and arc groove 3.2 matched in clearance on the housing 3 left sheets on the small end left side.Cutterhead 4 large end faces are provided with cannelure 4.2 and cooperate formation location swing mechanism with pivot pin 3.4.Torque spring 5 is for holding the power element in this utility model, and torque spring 5 is sleeved on annulus 3.5 outer walls and constitutes fulcrum, and an end is put forth effort on housing 3 right sheet bases, and an end roof pressure of pretension constitutes mechanism to be revolved as shown in Figure 1 on limit, cutterhead 4 big end left side.Described plug-in unit 2 is a kind of movable parts, is inserted into switch 1 and the vertical junction of housing 3 upper left corner breach, and switch 1 withstands cutterhead 4 and constitutes safety structure.During this utility model practical application, be placed on medical miniature recessing tool housing 3 bottom surfaces and examined on the patient's finger, as shown in Figure 1, after pulling out plug-in unit 2,1 initial stage of pull switch makes cutterhead 4 dextrorotation to the right, when switch 1 misses cutterhead 4, cutterhead 4 drive cutter hubs 6 are left-handed under the effect of torque spring 5, when cutterhead 4 was threaded to 3 vertical line position of casing shown in the accompanying drawing 2, cutter hub 6 points of a knife of setting-in exposed 0.9mm～1.1mm on the cutterhead 4 from open slot 3.3, and present embodiment is 1mm.The cutting edge of cutter hub 6 is towards the right side, and dextral cutter hub 6 is scratched and examined the patient and point, because the point of a knife length of exposing is certain, is 1mm with this notch depth of doing sampling, and otch fast, and the patient suffering is few.When cutter hub 6 dextrorotation to terminal during the position, point of a knife is hidden in housing 3 bottom surfaces as shown in Figure 3.This utility model is accomplished all notch depth unanimities from structure, guarantees that sampling is consistent, thereby improves detection accuracy.
