Abstract
The utility model discloses a combined cover of a hard opening pipe of an infusion bag, comprising a single-opening pipe, wherein the lower end of the single-opening pipe is connected with an infusion bag film; an opening pipe cover is used for sealing the single-opening pipe and has an integrated structure; a rubber plug is arranged in the opening pipe cover by secondary injection molding; and the rubber plug and the opening pipe cover form an integrated structure. The combined cover avoids the problem that the liquid leaks due to unstable connection of the cover in the combination, and can reduce the processing procedures, avoid the pollution in the combination of the cover, reduce the production cost and improve the connecting firmness of the hard opening pipe and the infusion bag film.
Description
Technical field
This utility model relates to the medical package field, specifically refers to the hard-mouth tube composite cover as the transfusion bag infusion channel.
Background technology
At present, the transfusion bag hard-mouth tube composite cover structure that can see as shown in Figure 1, include enclosing cover 1 ', inner cap 2 ' and be built in plug ' 3 between inner cap and the enclosing cover, enclosing cover 1 ' on have easy-to-draw medicated cap 4 ', open easy-to-draw medicated cap 4 ' can carry out puncture procedure.Said structure, enclosing cover, plug and inner cap all are parts independently, the three's is fixing fastening by engaging mode or screw thread rotation mode, and meeting generation connection is insecure in the anabolic process causes the leakage problem, and too much parts unavoidably cause the raising of production cost.
The utility model content
At the defective that exists in the prior art, the purpose of this utility model is to provide a kind of transfusion bag hard-mouth tube composite cover, avoided lid in anabolic process because of connecting the not firm leakage problem that causes, can reduce manufacturing procedure, avoid the pollution in the cover combination process, reduce production costs, and improve the firmness that hard-mouth tube is connected with the transfusion bag thin film.
Above-mentioned purpose is achieved through the following technical solutions:
Transfusion bag hard-mouth tube composite cover includes the single port pipe, and single port pipe lower end is connected with the transfusion bag thin film, mouth pipe lid is used for sealing up the single port pipe, it is characterized in that: described mouthful of pipe lid is structure as a whole, and plug is built in mouthful pipe lid by double injection molding, and a plug and a mouthful pipe lid are formed overall structure.
Described mouthful of pipe lid lid mouth is provided with the sealing film sheet.
Described sealing film sheet becomes the water droplet shape, and the tip position of water droplet shape is that holding of sealing film sheet torn the position.
The both sides of described single port pipe lower end connecting portion are provided with the extension fin, in order to improve the degree of being connected firmly and the reliability of single port pipe and non-PVC thin film.
Described mouthful of pipe covers end and is the plug containing cavity, and the plug containing cavity is one or more numbers.
Has the threaded side wall that increases fastening force in the described plug containing cavity.
Adopt the transfusion bag hard-mouth tube composite cover of said structure, mouth pipe lid is structure as a whole, reduced inner cap structure of the prior art, after the injection moulding of mouth pipe lid, plug is built in mouthful by double injection molding in the plug containing cavity of pipe lid, and a plug and a mouthful pipe lid are formed an overall structure, avoided lid in anabolic process because of connecting the not firm leakage problem that causes, can reduce manufacturing procedure, avoid the pollution in the cover combination process; The mode of mouth pipe lid mouthful employing film seal seals, and the water droplet shape of thin film can make to seal and open conveniently, and is reliable; In addition, be provided with the extension fin, improve the degree of being connected firmly and the reliability of single port pipe and non-PVC thin film at single port pipe and transfusion bag thin film link.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 2-6, transfusion bag hard-mouth tube composite cover, include single port pipe 1, single port pipe lower end connecting portion 11 is connected with the transfusion bag thin film, and a mouthful pipe covers 2 and is used for sealing up single port pipe 1, described mouthful of pipe covers 2 and is structure as a whole, the mouth pipe covers end and has plug containing cavity 3, and plug containing cavity 3 is one or more numbers, and plug 4 is built in the containing cavity 3 by double injection molding, have the threaded side wall 31 that increases fastening force in the plug containing cavity 3, a plug 4 and a mouthful pipe cover 2 forms overall structure.The mouth pipe covers 2 and is structure as a whole, reduced inner cap structure of the prior art, after the mouth pipe covers 2 injection mouldings, plug 4 is built in mouthful pipe by double injection molding and covers in 2 the plug containing cavity 3, a plug 4 and a mouthful pipe cover 2 forms overall structure, avoided lid in anabolic process because of connecting the not firm leakage problem that causes, can reduce manufacturing procedure, avoid the pollution in the cover combination process;
As shown in Figure 4, the both sides of single port pipe lower end connecting portion 11 are provided with extension fin 12, in order to improve the degree of being connected firmly and the reliability of single port pipe and non-PVC thin film.
As Fig. 2, shown in Figure 6, a mouthful pipe cover 2 lids and mouthful is provided with sealing film sheet 5,5 one-tenths water droplet shapes of sealing film sheet, and the position is torn for holding of sealing film sheet in the tip position 51 of water droplet shape, can make and seal unlatching conveniently, reliably.
