As this utility model preferred embodiment, the bottom of housing 1 is needle stand, and the tail end of needle bar fixed bar 2 is fixed on needle stand, and needle stand is provided with bending mouth 15.As preferred embodiment, bending mouth 15 is arranged in the both sides of needle stand, can more conveniently assemble thus.Bending mouth 15 is at least provided with one, also can be arranged on other position on housing.
The setting of bending mouth 15, can facilitate this blood taking needle structure to realize disposablely completing injection molding or injection moulding, after injection molding or injection moulding complete, only needs simple bending or pressing can complete the assembling of safety blood taking needle product.
As this utility model preferred embodiment, the tail end being positioned at housing 1 is provided with the adjutage 6 mated with housing 1 tail end, is provided with screens 61 of loading in adjutage 6, is provided with the screens 61 of loading of at least one in adjutage 6.As preferred embodiment, in each adjutage 6, be provided with the screens 61 of loading that at least one pair of is symmetrical.
As this utility model preferred embodiment, the bottom opening of adjutage 6, the tail end being positioned at adjutage 6 is provided with and coordinates the compound lock 62 that on blood collecting pen, compound lock hole is fixed.
As this utility model preferred embodiment, compound lock 62 is symmetrically arranged two projections in adjutage 6, each projection be taper, semicircle, trapezoidal in one, also can be other shapes.
This safety type blood collecting needle construction can coordinate blood collecting pen to use, now, the reset folder 22 that needle bar fixed bar 2 tail end is arranged or positor 23 can coordinate with the top of blood collecting pen and be fixed, after completing blood sampling by blood collecting pen, in the process that blood collecting pen is regained, can reply under blood collecting pen regains active force with the needle bar fixed bar 2 of blood collecting pen top secure fit.
Be blood collecting pen with the use of process in, screens 61 of loading can better realize and being fixedly connected with between blood collecting pen with compound lock 62, ensures better to connect effect.
Be provided with screens 61 of loading in adjutage 6, be at least provided with one, be preferably two, lateral symmetry is placed, the block device of strip in traverse, with specify blood collecting pen load device with the use of.Promote compound slide bar to retrodisplacement for blood taking needle 8 in the process of specifying blood collecting pen to be combined, reach the object of loading.After blood taking needle has been combined with appointment blood collecting pen, maintains compound slide bar in relevant position, kept state of loading.Unload at bullet when bullet unloads under the thrust of spring and pushed away blood collecting pen forward by the compound slide bar push rod that will load.Screens 61 of loading also can adopt semicircle, trapezoidal or other shape, modes of emplacement also can adopt place vertically, tiltedly put, other modes of emplacement such as asymmetric placement.
Be provided with compound lock 62 in this safety blood taking needle, be at least provided with one, be preferably the block devices of two groups of tapers, in upper and lower, symmetrical placement on adjutage 6, with specify the compound lock hole of blood collecting pen with the use of.With compound lock hole in conjunction with time, as clamping device, form an inside pressure, by blood taking needle together with a body compact siro spinning technology.Coordinate with compound lock hole, reach the object keeping state of loading and bullet to unload state after bonding simultaneously.Coordinate with compound lock hole, reach the object keeping bullet to unload state after firing.Compound lock 62 also can adopt semicircle, trapezoidal or other shape, modes of emplacement also can adopt place vertically, tiltedly put, other modes of emplacement such as asymmetric placement.
As this utility model preferred embodiment, the outside being positioned at housing 1 is provided with housing and fixes buckle 7.Housing is fixed buckle 7 and also can be placed on inside housing 1, between housing 1 and needle stand.
As this utility model preferred embodiment, the tail end of needle bar fixed bar 2 is provided with the trigger shaft extended back.Preferably cylindrical, facilitating staff pressing and blood collecting pen percussion hammering to send out, also can be other shape.
As this utility model preferred embodiment, the tail end of needle bar fixed bar 2 is provided with outward extending gripper shoe.Be preferably both sides to arrange, as percussion fulcrum during handled easily person one-handed performance.
As this utility model preferred embodiment, the upper end of housing 1 is narrowed to top, is also provided with the needle bar fixed bar motion guide rail that guiding needle bar fixed bar 2 slides in housing 1.
As this utility model preferred embodiment, needle bar fixed bar motion guide rail is provided with the localizer revising needle bar fixed bar 2 movement locus, be preferably more than two-stage, subordinate's localizer positioning precision higher than the positioning precision of higher level's localizer.The present embodiment adopts three grades, is respectively column localizer, taper localizer and plane localizer.
After blood taking needle percussion, needle bar fixed bar 2 is from easy knick point or deviate from from resetting block, along needle bar fixed bar motion guide rail forward slip, needle bar fixed bar 2 is introduced into column localizer and tentatively revises needle bar fixed bar 2 movement locus, enter taper localizer again, secondary fine setting revises needle bar fixed bar 2 movement locus to plumbness, then enters plane positioning device and guarantee needle stand movement locus thus make needle point and needle outlet be in plumbness, and needle point is given prominence to needle outlet and completed percussion.
This safety type blood collecting needle construction, by arranging trigger shaft and gripper shoe, can realize the singlehanded percussion to blood taking needle.Also by arranging adjutage 6, compound lock 62 and screens 61 of loading, coordinate with appointment blood collecting pen and reach better blood sampling effect, more excellent reached one hand, both blood collecting pens are general.
As this utility model preferred embodiment, be provided with can to extending out the skin tensioner 9 of stretching for housing 1.
Skin tensioner 9 is positioned at the outside on housing 1 top, when blood taking needle uses, leans on human body skin by housing 1 top, then skin tensioner 9 is pressed to both sides distortion expansion, can tighten the skin of blood sampling site.The setting of skin tensioner 9 can make needle point more successfully puncture and enter tissue, alleviate the pain of patient during acupuncture.
Device of the present utility model, structure is simple, assembly is few, assembling is easy, reliability is high, use safety.By arranging bending part and bayonet unit, disposablely can complete injection molding or injection moulding, only needing simple bending and pressing can complete the assembling of product.Greatly save material, reduce operation and reduce production cost, obviously alleviate medical institutions and patient's financial burden.
This blood taking needle structure can reach when supporting the use with supporting blood collecting pen a key pulls the trigger the function of fast loading that thorax and bullet unload thorax, handled easily human users.
Certainly, this utility model is created and is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to this utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
