Abstract
The utility model discloses an external compression soft bag connecting pipe orifice cover, which comprises a plastic connecting pipe (1), a rubber plug (2) and a pipe orifice connecting cover (3). The utility model is characterized in that the middle lower part of the plastic connecting pipe (1) takes a shape of flat trumpet; the longitudinal section of the rubber plug (2) is of a T-shape; the outer edge of the rubber plug (2) is pressed on the upper edge of an upper port of the plastic connecting pipe (1); the outer edge of the upper port of the plastic connecting pipe (1) is provided with a reverse tooth-shaped bulge (4); the structure of the pipe orifice connecting cover (3) corresponds to that of the outer edge of the upper port of the plastic connecting pipe (1); the structures of the pipe orifice connecting cover (3) and the plastic connecting pipe (1) both correspond to that of the rubber plug (2); and the plastic connecting pipe (1), the rubber plug (2) and the pipe orifice connecting cover (3) are in close fit with each other. The internal caliber of the plastic connecting pipe of the utility model is increased from top to bottom so that the medicinal liquid can flow in or flow out smoothly. The outer edge of the rubber plug is pressed on the upper edge of the plastic connecting pipe and is compressed and buckled by the pipe orifice connecting cover and the plastic connecting pipe so that the rubber plug cannot move downward to enter the pipe when being punctured. The external compression soft bag connecting pipe orifice cover has the advantages of safe puncture, smooth liquid flowing and good using effect.
Description
Affiliated technical field
This utility model belongs to the drug packaging field, a kind of specifically soft bag connection tube flap.
Background technology
At present, the packing of some transfusion medications is to adopt non-PVC-soft-bag, and its key position is the connection tube flap, and the structure influence at this position is to the cost and the result of use of packaging bag.In the prior art, JIUYUE in 2006 State Intellectual Property Office's Granted publication on the 6th one key name be the patent of " non-PVC-soft-bag transfusion dosing connection tube flap ", the patent No. is: ZL200520085693.5; Granted publication number is CN2812919Y.This patented technology structure comprises: rubber stopper and mouth of pipe connection cover in plastic union pipe, the mouth of pipe, its innovative point is the flat pipe of elastic closure for the plastic union pipe lower end.The deficiency that this patented technology exists is: the end face middle part of rubber stopper is the boss platform, and the middle part, bottom surface is a pit, in use, causes rubber stopper to move down easily with pin puncture rubber stopper, and very the person can push in the pipe; In addition, the rubber stopper of this structure is stressed not steady when puncture, and operation has some setbacks or stings partially.The plastic union pipe lower end of this technology is the flat pipe of elastic closure, under the situation of the thin flat and latus rectum of pipeline, often causes by the medicinal liquid in the mouth of pipe injection can be trapped in the flat pipe, need just can enter in the bag by external force, has brought inconvenience to operation.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved soft bag connection tube flap is provided, and its puncture flow liquid is smooth and easy, easy and safe to operate, and result of use is good.
For reaching above-mentioned purpose, this utility model is taked following technical scheme: this utility model includes: plastic union pipe, rubber stopper and mouth of pipe connection cover, it is characterized in that: the middle and lower part of plastic union pipe is flat horn-like, the rubber stopper vertical profile is "T"-shaped, and its outer is pressed in the upper edge of plastic union pipe upper port.
This utility model is taked technique scheme, have following beneficial effect: this utility model is designed to the middle and lower part of plastic union pipe flat horn-like, the down interior bore of Guan Yue is big more, thereby the orifice area of bottom is increased, and makes things convenient for medicinal liquid to flow in the mouth of pipe, flow out.In the process of normally making up a prescription, do not accumulate medicinal liquid in the pipe, medicinal liquid can flow in the soft bag fast, makes the full and uniform mixing of medicinal liquid energy.The rubber stopper outer is pressed in the upper edge of plastic union pipe upper port, and is closely compressed by mouth of pipe connection cover and plastic union pipe and to fasten, and can not move down when it is stung to cause in the propulsion tube.This utility model is easy to make and operation, puncture safety, and flow liquid is smooth and easy, and result of use is good.
Description of drawings
Below in conjunction with drawings and Examples this utility model is elaborated:
Fig. 1 cuts open figure for the main TV structure of this utility model specific embodiment.
Fig. 2 cuts open figure for the side-looking structure of this utility model specific embodiment.
Labelling among the figure: 1-plastic union pipe, 2-rubber stopper, 3-mouth of pipe connection cover, 4-projection.
The specific embodiment
By Fig. 1, shown in Figure 2, this utility model includes: plastic union pipe 1, rubber stopper 2 and mouth of pipe connection cover 3, the middle and lower part of plastic union pipe 1 are flat horn-like, that is: it opens wide enlarging in both sides to the left and right, it is big that internal diameter becomes, and front and back are constant, is convenient to bonding with soft bag like this.Rubber stopper 2 vertical profiles are "T"-shaped, and its outer is pressed in the upper edge of plastic union pipe 1 upper port.
The upper port outer of this utility model plastic union pipe 1 is provided with pawl shape projection 4, and mouth of pipe connection cover 3 is corresponding with the upper port outer structure of plastic union pipe 1, and the two is all corresponding with rubber stopper 2 structures, and the three closely cooperates.
This utility model plastic union pipe 1 upper orifice is circular, fades to flat ellipse downwards, and main looking is the flat horn-like of back-off, and the middle and lower part intracanalicular type is " eight " font.
This utility model plastic union pipe 1 afterbody is the flat ellipse hard tube, pipe and film are easily welded, film is not yielding, there is not the welding blind spot, and the each several part pressurized is even when film and mouth of pipe welding, in the pressing process, make the degree of drawing of film little, on soft bag, can weld in the lump two or more, so also be applicable to the occasion of double bimouth pipe or many mouthfuls of pipes.
