Abstract

The invention relates to an infusion bag connector. The infusion bag connector comprises a fixed base, a liquid inlet pipe, a medicine storage chamber and an outer cover connecting part, wherein the periphery of the fixed base is fixed between inner membranes of an infusion bag body; the fixed base gradually thins and performs smooth transition from the middle to the two ends; thin edges are arranged at the two tail ends of the fixed base; one end of the liquid inlet pipe is connected with the fixed base, is arranged in the center of the fixed base and runs through the fixed base, and the other end of the liquid inlet pipe is connected with the medicine storage chamber; the liquid inlet pipe connected with the medicine storage chamber is cylindrical; the cross section of the liquid inlet pipe which is connected with and runs through the fixed base is rhombic; the connecting part is a protruding edge formed at the tail end of the medicine storage chamber. The infusion bag connector has the beneficial effects that the fixing sealability of connection with an infusion bag is greatly improved by adopting an outer cover connector, and materials are further saved by adopting a reinforcing rib structure of the outer cover connector; the firmness and durability of an outer cover in the connection and using processes are reinforced by adopting a reinforcing plate; the outer cover connector is safe, reliable, convenient and feasible in the using process.

Description

technical field

[0001] The invention relates to the technical field of medical packaging, in particular to an interface for an infusion bag. Background technique

[0002] With the widespread application of infusion therapy, the infusion method has undergone a development process from open, semi-open to fully enclosed, and the infusion set has changed from the initial glass bottle to the current non-PVC composite film soft bag. In order to realize infusion, the soft bag is generally provided with an infusion bag button-type combined cover and an interface matched with it, so that it is convenient for adding medicine or inserting a needle. In the prior art, the liquid tube of the interface of the infusion bag is usually cylindrical, so that when in use, the circular liquid tube is completely immersed in the liquid medicine, which is not conducive to the smooth dripping of the liquid medicine. Contents of the invention

[0003] In view of the above-mentioned problems in the ...

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Such as figure 1 As shown, the outer cover interface 2 of the present invention includes a fixing seat 21 , a liquid pipe 22 , a drug storage chamber 23 and a connecting portion 24 . The fixing seat 21 gradually becomes thinner and transitions smoothly from the middle to both ends, and the cross-sectional shape of the fixing seat 21 is substantially a rhombus shape. combine figure 1 and 2 It can be seen that there are thin edges 210 at both ends of the fixing seat 21 . It can be seen from the figure that the liquid tube 22 is placed in the center of the fixed seat 21, runs through the fi...
