Abstract
A soft packing bag of sodium bicarbonate injection is characterized in that a medical flexible plastic inner bag used for being filled with sodium bicarbonate injection is arranged in a soft outer protection bag made of gas-tightness material in a vacuum way, and a communication structure closed through a closed structure is arranged on the inner bag. The soft packing bag can enable the sodium bicarbonate injection in the inner bag to be protected by double gas-tightness material and relieve the pressure generated by thermal dilatation during sterilization heat treatment to the utmost extent, so that the whole packing bag, especially the inner bag, is ensured to be prevented from such damage as breakage or gross distortion and the like; and the soft packing bag of the sodium bicarbonate injection is easy to manufacture, process and store, and is beneficial to ensure the quality of the sodium bicarbonate injection.
Description
Technical field
This utility model relates to the soft packaging bag of a kind of packing bag for medical use, particularly a kind of sodium bicarbonate injection.
Background technology
In the medical packaging field, flow of infusate is adopted medical flexible packaging made from plastic to become present main flow trend and is widely used.For sodium bicarbonate injection, because sodium bicarbonate own characteristic decision, it can decompose and produces carbon dioxide in the process of storing, and the pH value of injection is changed, and is injected into the pH value disorder that can cause body fluid behind the human body.By chemical general knowledge as can be known, the decomposition of sodium bicarbonate is a reversible process, as long as the carbon dioxide that decomposes does not run off, this reversible reaction system can be in a kind of poised state.
Given this, provide a kind of plastic packaging bag of sodium bicarbonate injection Chinese patent 200720177747.X number, what adopt is that bag at gas-barrier material protects and is provided with a plastics inner bag that can hold sodium bicarbonate injection in the bag, and all is filled with carbon dioxide respectively in inner bag and bag protect cavity between bag and inner bag.Practice is found, this kind packaging bag remain open defect be: bag and the carbon dioxide that fills in the cavity between inside and outside two bags within it, under the higher temperature of heat sterilization, can violently expand, can cause the gross distortion of plastics inner bag and/or outer bag even break waiting damage, seriously influence the quality that sodium bicarbonate injection packs and the use of injection.
The utility model content
At above-mentioned situation, this utility model will provide a kind of soft packaging bag of sodium bicarbonate injection of new model, to address the above problem.
The basic structure of sodium bicarbonate injection soft packaging bag of the present utility model, be outside gas-barrier material soft, to protect in the bag to be provided with the medical flexible plastic inner bag that is used to fill with sodium bicarbonate injection, also be provided with the connectivity structure that seals through enclosed construction on this inner bag as required in the usual way with vacuum mode.
In the soft packaging bag of above-mentioned sodium bicarbonate injection, the connectivity structure on the said medical flexible plastic inner bag can be the simply connected form of tubes, also can be doubly-linked siphunculus form, or other can satisfy the structure of the appropriate format that uses needs.
In the soft packaging bag of the above-mentioned sodium bicarbonate injection of this utility model, allow as said should soft outer gas-barrier material that protects bag, can adopt as comprise above-mentioned document now in the document mode of report and/or use realize.Adopt the production method of the sodium bicarbonate injection of the above-mentioned packaging bag of this utility model, as comprise perfusion, packaging bag sealing and Vacuum Package etc. to medicinal liquid, all the production process with existing like product is as good as, and all can realize according to the process of present routine.
Compare with sodium bicarbonate injection soft packaging bag currently reported and/or that use; the remarkable advantage of this utility model said structure packaged bag is embodied in: because the coefficient of expansion of liquid is much smaller than gas; after filling with sodium bicarbonate injection medicine and encapsulation in the inner bag; not only can be subjected to inner bag and protect outward the bag duplicate protection; and since inner bag and in; all there is not gas to exist between outer bag; therefore when heat sterilization; can alleviate inner bag to greatest extent and protect bag outward because of the suffered compressing power of thermal expansion; prevent and avoided inner bag and protect outward the bag distortion or break, guaranteed the quality of sodium bicarbonate injection.Packaging bag of the present utility model also helps producing, processes and stores.
Below in conjunction with the specific embodiment, foregoing of the present utility model is described in further detail again by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of this utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of this utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
Description of drawings
Fig. 1 is the sketch map of a kind of version of soft packaging bag of this utility model sodium bicarbonate injection.
Fig. 2 is the sketch map of the another kind of version of soft packaging bag of this utility model sodium bicarbonate injection.
The specific embodiment
The soft packaging bag of this utility model sodium bicarbonate injection as shown in Figure 1, be outside gas-barrier material (specifically can with reference to aforementioned documents or other existing form) soft, to protect in the bag 4, be provided with the medical flexible plastic inner bag 2 that is used to fill with sodium bicarbonate injection with vacuum mode, on inner bag 2, also be provided with through form connectivity structures such as communicating pipe of enclosed construction sealing at present commonly used such as sealing plug or valve or connected entrances.This connectivity structure shown in the figure is simply connected pipe 1 form.
The sodium bicarbonate injection soft packaging bag of the another kind of form of this utility model that shown in Figure 2 is, the form that it is outer to protect bag 4 and inner bag 2 is identical with Fig. 1's, difference be on this medical flexible plastic inner bag 2 the connectivity structure employing be doubly-linked siphunculus 1,11 form.
Claims (3)
1. the soft packaging bag of sodium bicarbonate injection, it is characterized in that outside gas-barrier material soft, protecting in the bag (4) being provided with the medical flexible plastic inner bag (2) that is used to fill with sodium bicarbonate injection, also be provided with the logical structure of sealing on the inner bag (2) through enclosed construction with vacuum mode.
2. the soft packaging bag of sodium bicarbonate injection as claimed in claim 1 is characterized in that the connectivity structure on the said medical flexible plastic inner bag (2) is simply connected pipe (a 1) form.
3. the soft packaging bag of sodium bicarbonate injection as claimed in claim 1 is characterized in that said medical flexible plastic inner bag (2) connectivity structure is doubly-linked siphunculus (1, a 11) form.
