Abstract
The present utility model relates to a medical device. Aims to provide a residue-free interface for a double-tube infusion bag, which has the characteristics of smooth liquid outlet and less residue of liquid medicine in the bag. The technical scheme is a double-tube infusion bag is with no interface that remains, its characterized in that: the top orifice area of the infusion hole is larger than the cross-sectional area of the inner cavity of the infusion hole.
Description
Technical Field
The utility model relates to a medical apparatus, in particular to a residue-free interface for a double-tube infusion bag.
Background
The prior intravenous infusion bag mainly comprises a bag body made of PP film and an interface arranged at the opening position of the bag body. The interface has the functions of sealing the opening of the sealed bag body, guiding the external medicine to be injected into the bag body smoothly and guiding the internal medicine liquid to flow out smoothly.
In the actual transfusion process, a small amount of liquid medicine remained in the transfusion bag is difficult to smoothly discharge in the last stage of transfusion, and can not be effectively utilized and only be discarded, but when high-grade and expensive medicines are used, larger waste is caused if the medicines are directly discarded, and further improvement is needed.
Disclosure of Invention
The utility model aims to overcome the defects in the background technology and provide a residue-free interface for a double-tube infusion bag, which has the characteristics of smooth liquid outlet and less residue of liquid medicine in the bag.
The technical scheme of the utility model is as follows:
the residue-free interface for the double-tube infusion bag comprises a base, and a medicine adding tube and an infusion tube which are vertically fixed on the bottom surface of the base; an axially extending infusion hole is formed in the infusion tube; the dosing tube is internally provided with a dosing hole extending axially; the infusion hole and the dosing hole extend to the top surface of the base; the method is characterized in that: the top orifice area of the infusion hole is larger than the cross-sectional area of the inner cavity of the infusion hole.
The top orifice of the transfusion hole is provided with a guide part extending towards the center of the base.
The guide part is connected with the inner wall of the transfusion hole through a guide surface which is obliquely arranged.
The projection of the base on the horizontal plane is ship-shaped.
The side of base is equipped with 3 strengthening ribs that the level was arranged respectively, still is equipped with toward the convex welding muscle of side on every strengthening rib.
The base both ends are equipped with the fin that vertical arrangement was arranged.
The beneficial effects of the utility model are as follows:
the utility model improves the structure of the transfusion hole (the guide part is added at the top of the transfusion hole), and the residual liquid medicine in the transfusion bag is guided by the guide part to rapidly flow into the transfusion tube and be discharged outwards, so that the liquid medicine in the transfusion bag can be completely discharged, the medicine waste is avoided, and the treatment effect of a patient is ensured.

Fig. 2 is a schematic cross-sectional structure of fig. 1.
Fig. 3 is a schematic top view of the present utility model.
Fig. 4 is a schematic view of the front view of the infusion bag.
Detailed Description
The present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to the following examples.
As shown in figure 1, the residue-free interface for the double-tube infusion bag comprises a base 1, a medicine adding tube 2 and an infusion tube 3. The infusion tube and the dosing tube are vertically fixed on the bottom surface of the base, the horizontal distance between the infusion tube and the dosing tube is 15-25mm, an axially extending infusion hole 3.1 is arranged in the infusion tube, an axially extending dosing hole 2.1 is arranged in the dosing tube, and the infusion hole and the dosing tube hole both extend upwards to the top surface of the base.
As shown in fig. 3, the projection of the base on the horizontal plane is ship-shaped, and the two ends of the base are provided with fins 1.3 extending outwards. As shown in fig. 1, 3 reinforcing ribs 1.1 extending horizontally are arranged on the side face of the base, a welding rib 1.2 protruding horizontally is further arranged on each reinforcing rib, the welding ribs are arranged in the middle of the reinforcing ribs, and two ends of the welding ribs extend horizontally to the fins at two ends. The base adopts the ship structure can reduce the area of contact of the bag body and the base, and simultaneously the welding rib increases the fusion effect of the welding position, thereby effectively ensuring the integral tightness of the infusion bag.
As shown in fig. 3, a guide part is arranged at the top of the infusion hole, and the guide part is arranged at one side of the infusion hole facing the center of the base and extends towards the center of the base.
As shown in fig. 3, in this guide portion: the top orifice of the infusion hole is egg-shaped, the left side edge 3.2 of the orifice protrudes towards the center of the base, the distance between the left side edge of the orifice and the central axis of the infusion hole is larger than the distance between the right side edge 3.3 of the orifice and the central axis of the infusion hole, and the left side edge of the orifice is connected with the inner wall of the infusion hole through a guide surface 4 which is obliquely arranged (arc transition). The guide surface is arranged in the base, and the cross-sectional area of the infusion hole in the base gradually decreases from top to bottom. The guide surface and the left edge of the orifice form the guide part.
As shown in fig. 2, since the infusion tube is disposed on the right side of the base, the guide portion is disposed on the left side of the infusion hole. In the infusion process, when only a small amount of liquid medicine is left in the infusion bag, the residual liquid medicine can quickly enter the infusion hole through the guide part and be discharged outwards, so that the liquid medicine residue in the infusion bag is avoided.
