Abstract
The utility model discloses a split type insulin injector, which is characterized in that a movable needle seat is arranged in the tube neck of an outer sleeve, the movable needle seat is composed of an upper needle seat and a lower needle seat, the upper needle seat and the lower needle seat adopt an integrated structure, an interference sealing ring is arranged at the lower needle seat, a convex ring is arranged on the outer wall of the lower end of the lower needle seat, a lower step matched with the convex ring is arranged at the lower end of the tube neck of the outer sleeve, and an upper step is arranged in the tube neck of the outer sleeve; the inner hole of the tube neck of the outer sleeve of the insulin injector can be enlarged through the design structure of the product, the die core is enlarged during the injection molding process, so that the center can be positioned. The split type insulin injector has the advantages that production difficulty is reduced, the product condemnation factor of the product is controlled efficiently, the production cost is lowered, the residual quantity can be reduced to the largest extent through the built-in needle seat, the injection molding of the product is convenient, the packaging technology is convenient, the working stability is high, the structure thereof is reasonable, and the design concept is novel.
Description
Technical field:
This utility model relates to the technical field of medical device, a kind of specifically split type insulin syringe, particularly its mechanical connecting structure.
Background technology:
At present, existing international standard of insulin syringe and national sector standard, ISO 8537:1991 and YY 0497-2005 have stipulated all in two standards that insulin syringe is divided into 8 types.Class1-type 4 has the 6:100 conehead, and type 5-type 8 is to have fixed needle.Though difficulty was little when Class1-type 4 was made, the medicinal liquid residual quantity is big when being to use; Though the medicinal liquid residual quantity was little when type 5-type 8 was used, because overcoat is elongated, overcoat top endoporus is tiny, so the core of overcoat can't live the center surely, and crooked easily during the overcoat injection mo(u)lding, manufacture difficulty is big, the cost height.Two class syringes always have certain defective.
Documents, the patent No.: ZL200420082178.7, publication number: CN2722937, the patentee: Longde Medical Apparatus and Instruments Co. Ltd. Hangzhou discloses a kind of " the aseptic insulin syringe of disposable use " in this case, it includes: overcoat, core bar, piston, pin medicated cap and end cap, it is characterized in that: piston is located at the top of core bar, and is located at the inside of overcoat, and entry needle is made up of needle tubing and needle stand, needle tubing is arranged on the needle stand and bonding connection, and the pin medicated cap is in the outside of entry needle; The lower curtate of needle stand and needle tubing stretches into the least significant end in the overcoat; Piston nose face and injection needle are accessibly connected.
Above-mentioned patent is a prior art, but still has the weak point that can't overcome, so still need prior art is further improved.
Summary of the invention:
The purpose of this utility model is to provide a kind of split type insulin syringe, it effectively reduces the manufacture difficulty of syringe, reduces the scrappage of product in manufacture process, reduces manufacturing cost, reduce the medicinal liquid residual quantity, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, technical scheme of the present invention is: split type insulin syringe, it mainly comprises in overcoat, the needle tubing overcoat and is provided with core bar, it is characterized in that: be provided with the active pointer headstock in the tube neck of described overcoat, described active pointer headstock is made of last needle stand and following needle stand, last needle stand and following needle stand are into a single integrated structure, following needle stand place is provided with the interference sealing ring, the outer wall of following needle stand lower end is provided with bulge loop, and outer sleeve neck lower end is provided with getting out of a predicament or an embarrassing situation of matching with bulge loop, is provided with in the outer sleeve neck and tops bar.
The utility model discloses a kind of split type insulin syringe, it is provided with the active pointer headstock in insulin syringe outer sleeve neck, movable needle holder is assembled by the jacking of overcoat top from top to bottom in assembling process, because the active pointer headstock is made of last needle stand and following needle stand, and the following needle stand of the diameter of last needle stand is big, topping bar in such respective outer side edges outer sleeve neck, can play position-limiting action, make that the active pointer headstock can be again to bottom offset, after the active pointer headstock has assembled fully, the bulge loop of following needle stand lower end protrudes in getting out of a predicament or an embarrassing situation of outer sleeve neck bottom, such structural design can prevent that the active pointer headstock upwards is subjected to displacement, and the interference sealing ring that is arranged on down the needle stand place can play sealing function, such product design structure can be so that the endoporus of insulin syringe outer sleeve neck increases, injection moulding adds man-hour, mold cores just increases, can live the center surely, manufacture difficulty reduces, effectively control the scrappage of product, reduce and make finished product, and built-in needle holder can also at utmost reduce residual quantity, for accurately controlling syringe insulin medicinal liquid, the patient provides possibility, the product injection moulding is convenient, packaging technology is convenient, the job stability height, and it is rational in infrastructure, the design concept novelty.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to the accompanying drawings, this utility model further is described
This utility model is a kind of split type insulin syringe, as shown in fig. 1, it mainly comprises overcoat 1, needle tubing 4, be provided with core bar 2 in the overcoat 1, it is characterized in that: be provided with active pointer headstock 3 in the tube neck of described overcoat 1, described active pointer headstock is made of last needle stand 5 and following needle stand 6, last needle stand and following needle stand are into a single integrated structure, following needle stand place is provided with interference sealing ring 7, the interference sealing ring is than the big 0.05mm-0.15mm of tube neck endoporus, so can finely play sealing function, the outer wall of following needle stand lower end is provided with bulge loop 8, and outer sleeve neck lower end be provided with match with bulge loop get out of a predicament or an embarrassing situation 9, be provided with in the outer sleeve neck and top bar 10, the described diameter of going up the diameter of needle stand 5 greater than following needle stand 6, the big up and small down structure of whole active pointer headstock.
The product design structure of this novelty can be so that the endoporus of insulin syringe outer sleeve neck increases, make injection moulding add man-hour, mold cores effectively increases, and can live the center surely, reduce the manufacturing process difficulty, effectively the scrappage of control product reduce and make finished product, and built-in needle holder can also at utmost reduce residual quantity, for accurately controlling syringe insulin medicinal liquid, the patient provides possibility, the product injection moulding is convenient, and packaging technology is convenient, the job stability height.
