Abstract

The utility model discloses a rigid opening tube type transfusion soft bag, comprising a transfusion bag body, combination covers, and transfusion opening tubes. The transfusion opening tubes are disposed between the transfusion bag body and the combination covers and are formed by one-off injection molding with PP material; each transfusion opening tube comprises a first opening tube, a second opening tube and a connecting part; the connecting part is disposed between the first opening tube and the second opening tube; and the section of the connecting part is a trapezoid with a wide upper side and a narrow lower side. The transfusion opening tubes are formed by one-off injection molding with the PP material, and, compared with a conventional soft tube, can be welded and encapsulated with the transfusion bag body through hot seal easily and can be sealed and covered by the combination covers through the hot seal easily, thereby improving efficiency greatly. The rigid opening tube type transfusion soft bag is also characterized by concise and elegant appearance and less material, thereby enjoying favorable application prospect.

Description

A kind of hard-mouth tube formula transfusion flexible bag

Technical field

This utility model relates to technical field of medical instruments, particularly relates to a kind of hard-mouth tube formula transfusion flexible bag.

Background technology

Transfusion flexible bag is a kind of medical transfusion device that is widely used at present, and along with the change of medical transfusion mode and the continuous development of medical treatment device technical field, infusion model has experienced transformation from open to fully closed; And infusion apparatus is also thereupon by the transformation to plastic bottle of originally vial; Transfusion flexible bag comprises that mainly transfusion bag body and the composite cover that is installed in its top constitute, and is connected with the infusion port pipe between composite cover and the transfusion bag body, and what the mouth pipe of existing widely used transfusion flexible bag adopted is two flexible pipe heat-sealing ways of connecting; Bag-making equipment is required high; When flexible pipe and the heat-sealing of transfusion bag body, need in flexible pipe, add a metal bar, make that flexible pipe keeps original shape when the heat-sealing welding is exerted pressure; This shows when flexible pipe seals; The requirement of bag technology than higher, technology more complicated and there is the serious phenomenon of waste of material, in view of above-mentioned defective, is necessary the design of existing transfusion flexible bag is proposed new improvement.

The utility model content

To the problems referred to above, this utility model provide a kind of manufacturing process simple, save the novel hard-mouth tube formula infusion tube of material and appearance looks elegant.

This utility model is that the technical scheme that its technical problem of solution is adopted is:

A kind of hard-mouth tube formula transfusion flexible bag comprises transfusion bag body, composite cover and infusion port pipe, and said infusion port pipe is located between said transfusion bag body and the composite cover, it is characterized in that: said infusion port pipe is a PP material single injection-molded hard-mouth tube.

As the further improvement to such scheme, said infusion port pipe comprises first mouthful of pipe, second mouthful of pipe and connecting portion, and said connecting portion is located between first mouthful of pipe and the second mouthful of pipe.

In addition, the cross section of said connecting portion is following narrow trapezoidal of last hem width.

The beneficial effect of this utility model is: this utility model is as a kind of hard-mouth tube formula transfusion flexible bag; The infusion port pipe is a PP material single injection-molded hard-mouth tube; For traditional flexible pipe; This utility model is easy to connect with the soldering and sealing of transfusion bag calor innatus, fill, and is convenient to and composite cover heat-sealing capping, has therefore greatly improved efficient; In addition, this utility model also possesses the succinct attractive in appearance and few advantage of materials of profile, therefore possesses good prospects for application.

Description of drawings

Below in conjunction with accompanying drawing and embodiment this utility model is described further:

Fig. 1 is this utility model overall structure sketch map;

Fig. 2 is this utility model infusion port tubular construction sketch map.

The specific embodiment

With reference to Fig. 1-Fig. 2, a kind of hard-mouth tube formula transfusion flexible bag comprises transfusion bag body 1, composite cover 2 and infusion port pipe 3; Infusion port pipe 3 is located between said transfusion bag body 1 and the composite cover 2, and said infusion port pipe 3 is PP material single injection-molded hard-mouth tube, and infusion port pipe 3 comprises 31, second mouthfuls of pipes 32 of first mouthful of pipe and connecting portion 33; Connecting portion 33 is located between 31 and second mouthfuls of pipes 32 of first mouthful of pipe, and the cross section of connecting portion 33 is following narrow trapezoidal of last hem width, the described infusion port pipe 3 of this utility model; Be applied to transfusion bag body 1; Its effect mainly is as dosing mouth and infusion port usefulness, and the general form of heat-sealing that adopts makes said infusion port pipe 3 be connected with transfusion bag body 1 on the industry, and this utility model infusion port pipe is a PP material single injection-molded hard-mouth tube; For traditional flexible pipe; This use is novel to be easy to and the 1 heat-sealing welding of transfusion bag body, fill, and is convenient to and composite cover 2 heat-sealing cappings, has therefore greatly improved efficient.

More than the preferable enforcement of this utility model is specified; Certainly; This utility model can also adopt the form different with above-mentioned embodiment; These do not constitute any restriction to this embodiment, and those of ordinary skill in the art should belong in the protection domain of this utility model conversion of under the prerequisite of this utility model spirit, being done that is equal to or corresponding the change.
