Abstract
The utility model discloses an assembled connector for soft transfusion bag, which comprises a connecting head, a butyl rubber plug and a top cover. Wherein, a pore at one end of the connecting head is corked with the butyl rubber plug and provided a collar flange. The top cover can be integrated into a whole by a retainer ring. An upper end face of the collar flange on the connecting head is provided with an annular clamping groove. A lower end of the retainer ring can be closely retained into the annular clamping groove to press the butyl rubber plug and seal the soft transfusion bag, thus preventing liquid medicine penetration and ensuring excellent sealing effect. Meanwhile, the retainer ring and clamping groove enhance connector strength. The utility model directly and hermetically connects the connecting head with the soft transfusion bag to thin wall of the sealed connecting head, enhance connecting head elasticity, eliminate hose between the connecting head and the transfusion bag and ensure more simple and rational structure.
Description
Technical field
This utility model relates to the accessory field of medical package container, specifically is the built-up joint of transfusion flexible bag.
Background technology
In the medical package field of containers, transfusion flexible bag is used very extensive, the union joint structure of transfusion flexible bag is so at present: connecting first end is the flexible catheter that connects on the transfusion flexible bag, the place, aperture of the other end is clogged by butyl rubber plug, the plug of butyl rubber plug is along fitting with the collar flange at place, union joint aperture, tight casing pressure one aluminium-plastic cap outside them, aluminium-plastic cap central authorities leave aperture, expose a part of butyl rubber plug surface.The transfusion flexible bag union joint of said structure is not fine at butyl rubber plug and union joint junction sealing, and the intensity of union joint is not high yet; In addition, transfusion flexible bag union joint and being connected by flexible catheter of soft bag connect, and structure is not quite reasonable.
The utility model content
At the defective that technique scheme exists, the purpose of this utility model is to provide the built-up joint of transfusion flexible bag, has the intensity height, good seal performance, simple and reasonable characteristics.
For achieving the above object, be achieved by the following technical solution:
The built-up joint of transfusion flexible bag, form by union joint, butyl rubber plug and top cover, one stomidium mouth place of union joint is clogged by butyl rubber plug, the place, aperture has collar flange, it is characterized in that: top cover is integral by a snap ring engagement connection, collar flange upper surface at union joint is provided with the ring-type slot, and the lower end of snap ring can closely be fastened in the ring-type slot.
Be respectively arranged with annular projection on the inside and outside wall of described snap ring lower end.
Has the annular recess that engages with snap ring inside and outside wall annular projection on the ring-type slot two side of described union joint.
The lower end of described union joint is connected with the direct driving fit of transfusion flexible bag, and the wall thickness of the union joint of driving fit connecting portion is less than the wall thickness of non-driving fit connecting portion, and its wall thickness range is between 0.45 millimeter～0.95 millimeter.
Adopt the built-up joint of the transfusion flexible bag of said structure, between union joint and top cover, be provided with snap ring, and be provided with in the collar flange upper surface of union joint and snap ring can closely engage the ring-type slot of sealing, after linking into an integrated entity with top cover earlier by snap ring, butyl rubber plug clogs union joint, and the snap ring that will have top cover closely is fastened in the ring-type slot of union joint, push butyl rubber plug simultaneously, can realize the sealing that transfusion flexible bag connects, medicinal liquid can be to the dew that exosmoses, good sealing effect; Simultaneously, the snap ring of increase and the combination of slot have strengthened the intensity of joint more; In addition, in this utility model union joint is connected with the direct driving fit of soft bag, the wall thickness of driving fit part union joint reduces, and has increased the elasticity of union joint, does not re-use hose connection soft bag and union joint, and structure is simpler, reasonable.
Description of drawings
Fig. 1 is a STRUCTURE DECOMPOSITION sketch map of the present utility model;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
As Fig. 1, shown in 2, the built-up joint of transfusion flexible bag, by union joint 1, butyl rubber plug 2 and top cover 3 are formed, one stomidium mouth place of union joint 1 is clogged by butyl rubber plug 2, the place, aperture has collar flange 4, collar flange 4 upper surfaces are provided with ring-type slot 5, top cover 3 is integral by a snap ring 6 engagement connections, be respectively arranged with annular projection 61 on the inside and outside wall of snap ring 6 lower ends, 62, have on ring-type slot 5 two sides of union joint 1 and snap ring 6 inside and outside wall annular projections 61, the annular recess 51 of 62 engagings, 52, the lower end of snap ring 6 can closely be fastened in the ring-type slot 5; Direct driving fit is connected union joint 1 with soft bag, the wall thickness of the union joint of driving fit connecting portion 7 is less than the wall thickness of non-driving fit connecting portion 8, its wall thickness range is between 0.45 millimeter～0.95 millimeter, optimum embodiment is to select 0.7 millimeter wall thickness as driving fit connecting portion 7, increase the elasticity of union joint, do not re-used hose connection transfusion flexible bag and union joint.When using, after linking into an integrated entity with top cover 3 earlier by snap ring 6, butyl rubber plug 2 clogs union joint 1, and the snap ring 6 that will have top cover 3 closely is fastened in the ring-type slot 5 of union joint 1, pushes butyl rubber plug 2 simultaneously, can realize the sealing that transfusion flexible bag connects.
