Description
Technical field
This utility model relates to a kind of Dispoable medical blood taking needle, is specifically related to a kind of disposable notes formula blood taking needle.This blood taking needle can be used as and the matching used blood taking needle of reusable ejecting type inserting needle device (also claiming " hemostix "), also can be used as the blood sampling parts in " mini " disposable safe automatic blood-taking needle that carries ejection structure, all right conduct is blood taking needle manually.
Background technology
Along with medical level improves, disposable notes formula blood taking needle becomes basically universal in each medical institutions, and annual use amount is considerable, especially can with the supporting blood taking needle of reusable ejecting type inserting needle device, because effective, the low price of blood sampling is welcome by medical personnel very.So-called disposable notes formula blood taking needle is meant and adopts injection moulding process that needle body is fixed on blood taking needle in needle handle and the pin medicated cap.China's patent was announced a name on February 24th, 1999 and was called " disposable use sterile blood sampling pin ", and the patent No. is 97235181.1, and notification number is the utility model patent of CN2308348Y.This patent is the theme with disposable notes formula blood taking needle and discloses a kind of representative technical scheme, its structure mainly is made up of needle body, needle handle and the pin medicated cap of band needle point, needle body is fixed in the needle handle, needle point stretches out and is inserted in the pin medicated cap from an end of needle handle, and the transition structure by the envelope needle body between needle handle and the pin medicated cap fuses.The needle body of this structure blood taking needle adopts stainless steel material, and needle handle and pin medicated cap adopt plastics, during making needle body are put into the die cavity single injection-molded, and needle body is fixed in the needle handle and pin medicated cap that plastic material makes the most at last.Turn the pin medicated cap during use, make the fracture of pin medicated cap and needle handle transition junction, pull up the needle point that the pin medicated cap exposes certain-length then.Technique scheme is simple in structure, safe and reliable, easy to operate, has technique effect preferably undoubtedly, but in the practice because the restriction of injected plastics material and technological level, often make between needle body and the needle handle to be connected fastness not enough, when using because needle handle covers with pin fuses, need twist into two parts and tide over connection and just can extract pin lid, and in rotation pin lid process, cause needle body loosening easily, even connect the phenomenon that needle body is extracted together.With regard to its reason, the one, there is defective on the structure, specifically be that needle body is a cylinder, needle point then is made up of many corner angle, although the linkage section between pin lid and the needle point is shorter, its frictional force is often greater than the frictional force between needle handle and the needle body; The 2nd, the restriction of injected plastics material and technological level, we know that another key factor of above-mentioned generation band pin phenomenon is the material and the manufacturing process of needle handle and pin lid, if avoid being with the pin phenomenon to occur, then the more requirement of Gao Gengyan has been proposed for material and manufacturing process, correspondingly pay more costs.
Summary of the invention
This utility model purpose provides a kind of disposable notes formula blood taking needle structure that prevents that needle body from becoming flexible in needle handle.
For achieving the above object, the technical solution adopted in the utility model is: a kind of disposable notes formula blood taking needle, comprise needle body, needle handle and the pin medicated cap of being with needle point, needle body is fixed in the needle handle, needle point stretches out and is inserted in the pin medicated cap from an end of needle handle, transition structure by the envelope needle body between needle handle and the pin medicated cap fuses, and the needle body that is fixed in the needle handle is provided with locking fixed structure.
In the technique scheme, described locking fixed structure comprises following two kinds of situations:
1, locking fixed structure is made of the bending structure that is located on the needle body.About the position problems of bending structure, can be located at front portion, middle part and the rear portion of needle body, wherein be located at afterbody for best.About the shape problem of bending structure, as long as needle body vertically produces bending, in other words, needle body is provided with a bending at least.
2, locking fixed structure is the fixed block that is located on the needle body, and fixed block is fixedlyed connected with needle body.About the position problems of fixed block, can be located at front portion, middle part and the rear portion of needle body, wherein fixed block is located at the afterbody of needle body for best.In this programme, a fixed block can be set specially, and then fixed block is fixed on the needle body by fixed form; Also can directly fixed block be fixed on the needle body, be pricker or soldering piece such as fixed block.Obviously latter's structure is a preferred plan.Fixed block can also be made for materials such as plastics with certain intensity and caking ability, rubber, lucites, and its essential requirement is a needle body and the fastness that is connected that fastness is greater than needle body and needle handle that is connected of fixed block, and positive effect is so just arranged.
This utility model operation principle is: by a locking fixed structure is set on needle body, and locking fixed structure is injection molded into needle handle with needle body.Because needle body is provided with one section abrupt-change cross section structure, makes needle body be connected fastness and be multiplied, and be far longer than the fastness that is connected of needle point and pin medicated cap, so needle body can not take place when turning and pulling out the pin medicated cap become flexible and be with the pin phenomenon with needle handle.
Because the technique scheme utilization, this utility model compared with prior art has following advantage:
1, because this utility model needle body is provided with the technical measures of locking fixed structure, increased the resistance and the frictional force of needle body and needle handle greatly, made needle body become multiplication, thereby obtained good anti-loosening and anti-band pin effect with the fastness that is connected of needle handle.
2, because this utility model needle body is provided with the technical measures of locking fixed structure, can reduce material and Shooting Technique requirement to the plastics needle handle, it is easy and economical the manufacturing of blood taking needle to be become just add.
When 3, the locking fixed structure of this utility model adopts the bending structure, can make full use of the concordance that bending technique guarantees whole needle body length, thereby guarantee the concordance of needle point exposed length.Specifically can before bending technique, needle body be located in mould, needle point contact plastics king locating piece, needle body carries out bending to the needle body afterbody under clamp position, so just the error of needle body length can be stayed the backshank after the bending.
4, because this utility model needle body is provided with the technical measures of locking fixed structure, the phenomenon that needle body pushes up the handle of threading a needle can not take place in blood taking needle yet when using back needle handle, needle point and pin lid by accompanying drawing 5 mode plug-in mountings.
