Detailed description of the invention
With reference to Fig. 1��Fig. 5, the present invention is a kind of safety type blood collecting needle construction, including housing 1, the fixing bar 2 of needle bar being positioned at described housing 1 and the fixing blood taking needle 8 being positioned at the fixing bar 2 of needle bar; Described housing 1 is provided with needle outlet 11; The fixing locating piece 4 being provided with the fixing bar 2 of fixing needle bar between bar 2 and housing 1 of described needle bar.
Blood taking needle 8 is fixed in housing 1 by this safety type blood collecting needle construction, the blood taking needle unreasonable exposure when not using can be avoided, external force of blood taking needle 8 passing through when using triggers the fixing bar 2 of needle bar, fixing for needle bar bar 2 is skidded off from locating piece, and then promote blood taking needle 8, blood taking needle 8 can be promoted to take a blood sample through needle outlet 11, and this safety blood taking needle coordinates different structures can reach one-handed performance and/or the purpose used with supporting blood collecting pen, the operation of the blood sampling that can effectively ensure safety.
As the preferred embodiment of the present invention, blood taking needle 8 is the sharp object of needle-like, it would however also be possible to employ the sharp object of other shapes such as blade.
As the preferred embodiment of the present invention, blood taking needle 8 is provided with the needle point protection rod 23 of parcel needle point.
As the preferred embodiment of the present invention, the fixing bar 2 of needle bar extends forward the needle point protection rod 23 being provided with parcel needle point.
As the preferred embodiment of the present invention, the junction of needle point protection rod 23 and the fixing bar 2 of needle bar is provided with easily splits portion 24.
The setting of needle point protection rod 23 can avoid needle point to be exposed to the external world before use, rotates and comes off, can ensure sterilization effect during use. Easily splitting the setting in portion 24 can facilitate rotation to come off needle point protection rod 23, reaches needle point protection rod 23 and the fixing bar 2 of needle bar separates.
As the preferred embodiment of the present invention, the fixing bar 2 of needle bar stretches out and is provided with the stopping means 21 of fixing bar 2 both sides of needle bar, is provided with and coordinates stopping means 21 to make the resetting means that the fixing bar 2 of needle bar resets in housing 1.
As the preferred embodiment of the present invention, the Breadth Maximum of stopping means 21 forms the Breadth Maximum of hole more than the fixing bar of needle bar after coming off. So, stopping means 21 both can control blood taking needle 8 thorn on triggering and go out length, thus ensureing that blood taking needle 8 can rationally be taken a blood sample after stinging out, it is possible to prevent blood taking needle 8 from deviating from housing 1 after blood sampling completes from rear portion, and person of blood collecting, operator and scrap concrete person are not damaged.
Meanwhile, after blood sampling completes, resetting means coordinates stopping means 21 that blood taking needle 8 can be made to return in housing 1, and avoids causing cleaning trouble, and the injury to operator and patient.
As the preferred embodiment of the present invention, resetting means is that housing 1 extends internally and forms and to the elastic rod 3 of housing 1 bottom angled.
As the preferred embodiment of the present invention, housing 1 extends internally the elastic rod 3 being provided with to housing 1 bottom angled.
As the preferred embodiment of the present invention, housing 1 extends internally the elastic rod 3 being provided with to housing 1 bottom angled, elastic rod 3 and housing 1 integral production.
Under the form that arranges of this kind of resetting means, in the process that blood taking needle 8 stings out, elastic rod 3 is compressed, and after blood taking needle 8 stings out and puts in place and take a blood sample, elastic rod 3 replys original state under himself elastic reaction, can realize the perfect reset of blood taking needle 8.
Resetting means be provided with multiple way of realization, can pass through to arrange the associate members such as spring on the fixing bar 2 of needle bar, it is possible in housing 1, arrange independent reset components to realize the reset function of blood taking needle 8.
As the preferred embodiment of the present invention, housing 1 being positioned at the extension of needle outlet 11 both sides and is provided with shutoff damper, the Breadth Maximum on fixing bar 2 top of needle bar is more than the Breadth Maximum of needle outlet 11.
Shutoff damper is for being arranged at needle outlet both sides, and be the baffle plate of level at housing 1 private side, shutoff damper is when blood taking needle is launched and taken a blood sample, after blood taking needle is launched by needle outlet 11, the front end of the fixing bar 2 of needle bar can be blocked, it is prevented that the syringe needle of blood taking needle 8 excessively exposes by shutoff damper.
The top of shutoff damper and the fixing bar 2 of needle bar can be annulus and the cylinder of the different-diameter cooperated, it is preferred to the internal diameter of needle outlet 11 is less than the external diameter of the fixing bar 2 of needle bar, and shutoff damper is at least provided with one group.
Shutoff damper is preferably one group, it is arranged on the housing 1 of needle outlet 11 periphery and the front portion of the fixing bar 2 of needle bar, any part on housing 1, the fixing bar 2 of needle bar can also be arranged on, it is also possible to be internal part and or the external components various devices limiting the fixing bar displacement of needle bars that are arranged between housing 1 and the fixing bar 2 of needle bar alone or in combination.
The setting of shutoff damper, it is possible to limit the maximum displacement of the fixing bar 2 of needle bar well, control paracentesis depth, it is prevented that syringe needle excessively exposes.
As the preferred embodiment of the present invention, the fixing bar 2 of described needle bar is arranged independently of one another with housing 1.

As the preferred embodiment of the present invention, the tail end of the fixing bar 2 of needle bar is provided with outward extending gripper shoe. Gripper shoe is preferably both sides and arranges, as percussion fulcrum when facilitating operator's one-handed performance.
As the preferred embodiment of the present invention, the upper end of housing 1 is narrowed to top, is additionally provided with the fixing bar motion guide rail of needle bar that the fixing bar 2 of guiding needle bar slides in housing 1.
This safety type blood collecting needle construction is by arranging trigger shaft and gripper shoe, it may be achieved the singlehanded percussion to blood taking needle. Also by arranging adjutage 6, compound lock 62 and screens 61 of loading, coordinating, with specifying blood collecting pen, the effect that reaches more preferably to take a blood sample, more excellent reached one hand, both blood collecting pens are general.
As the preferred embodiment of the present invention, the extension of housing 1 top is provided with can to extending out the skin tensioner stretched.
Skin tensioner is positioned at the outside on housing 1 top, when blood taking needle uses, acts against on human body skin by housing 1 top, then skin tensioner is pressed to both sides deformation expansion, can tighten the skin of blood sampling site. The setting of skin tensioner can make needle point more successfully puncture entrance tissue, alleviates the pain of patient during acupuncture.
Assembly of the invention, simple in construction, assembly are few, assembling is easy, reliability is high, use safety. Saving material by designs such as external power, reducing operation thus reducing production cost, hence it is evident that alleviate medical institutions and patient's financial burden.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the premise without prejudice to spirit of the present invention, and these equivalent modification or replacement are all contained in the application claim limited range��
