Abstract

This application belongs to medical field, concretely relates to to a two port pipe infusion bag. The utility model provides a new infusion bag, this infusion bag has an oval part of separating in its bag portion welding on one's body, two parts about divideing into the liquid medicine room. This ellipse is separated the part and is played the cushioning effect to the bag body with oral siphon welding parts, has avoided the liquid medicine because of receiving the extrusion to cause the impact to bag body and oral siphon junction in transport or transportation to the seepage of bag body with oral siphon welding parts has effectively been prevented. In addition, the infusion bag of this structure makes simply, and with low costs, market prospect is good.

Description

A kind of transfusion bag

Technical field:

The application belongs to field of medicaments, is specifically related to a kind of double bimouth pipe transfusion bag.

Background technology:

Non-PVC infusion packaging is a kind of novel medicinal packaging material grown up the nineties in 20th century, its safety coefficient, ring Guarantor's indexs etc. are the most universally acknowledged.Adapt to international System of Infusion Drugs package development trend, pack replacement China now with non-PVC Popular vial, plastic bottle packing have become the certainty of development in China.Non-PVC packaging transfusion and glass infusion bottle and plastics Bottle packaging transfusion is compared, and outside atmospheric pressure compressing medicinal liquid in use can be relied on to ooze, enter medicine without extraneous air In liquid bag, greatly reduce the probability of secondary pollution, the feature that this is vial and plastic bottle does not possesses.Non-PVC-soft-bag is defeated The packaged form of liquid also has the process that a development is perfect.Initially application single tube list plug system, i.e. dosing and transfusion are at one Mouth pipe.The most rational most advanced non-PVC multi-layer co-extruded film bag packaging transfusion application double bimouth pipe system, i.e. dosing at present Mouth pipe separates with transfusion port tube.Its advantage is: one, dosing is carried out, thoroughly at two different mouth pipes respectively from the process of transfusion Avoid the cross-contamination of two processes；Two, the single more convenient feeding operations of dosing mouth pipe；Three, avoid make up a prescription between transfer To the pollution (because infusion port is not broken seal during this) during between transfusion, many bags of the most same patient infuses its safety The most prominent.There is the problem of mouth pipe and bag body connecting portion easy-to-leak liquid in the double bimouth pipe packed in flexible pouchy of domestic production at present, especially After carrying or transport, leakage problem is more prominent, and product quality exists the biggest potential safety hazard.

Based on the problems referred to above, design is invented a kind of novel transfusion bag and is just seemed particularly necessary.

Summary of the invention

For the problem overcoming double bimouth pipe transfusion bag of the prior art to exist, the application provides a kind of new transfusion bag, this transfusion Bag is welded with the partition member of ellipse its bag of body, and medicinal liquid room is divided into upper and lower two parts.This ellipse partition member Cushioning effect is played at bag body and mouth sealing of tube position, it is to avoid medicinal liquid in the carrying or transportation because of be squeezed and to bag body with Mouth pipe junction impacts, thus effectively prevent the seepage of bag body and mouth sealing of tube position.It addition, the transfusion bag of this structure, It is simple to manufacture, low cost, good market prospects.

To achieve these goals, the technical scheme that the application is used is as follows:

A kind of transfusion bag, including rectangular bag body, is medicinal liquid room by the inside of rectangular bag body, at one end marsupial of rectangular bag body minor face Body and mouth sealing of tube position, mouth pipe is connected to rectangular bag by this welding position；The top of rectangular bag body is provided with heat-sealing The partition member formed, described partition member is oval, and the longer axis parallel of this ellipse is in the width of rectangular bag body, and is shorter than The width of rectangular bag body；

Described partition member is real weldering or rosin joint, is made up of upper partition member and lower partition member, and upper and lower two partition members Form oval partition member；

The distance on two end-point distances rectangular bag height limits of the major axis of described oval partition member 7 is identical；

Mostly use, during transfusion bag vanning, the mode placed vertically or keep flat, often by from side or pressure effect above, by In transfusion bag material and mouth pipe material not exclusively as, welding between the two is also and insecure, it is easy to by outer masterpiece Separate with rear, cause the phenomenon of leakage to occur.According to statistics, the leakage position of more than 99% occurs in the weld part of transfusion bag and mouth pipe Position, and have oval partition member at the upper weld of transfusion bag, the instantaneous medicinal liquid gushed can be played certain cushioning effect, Decrease the impact to bag body Yu mouth pipe junction, it is therefore prevented that medicinal liquid is revealed；On the other hand, when transfusion, oval separation Parts are easy to medicinal liquid and are flowed at the mouth pipe of medicinal liquid room from both sides, it is therefore prevented that liquor residue, decrease medicinal liquid boil on the nape opposite the mouth pipe simultaneously and connect The pressure at place；

In sum, by arranging the partition member of ellipse in transfusion bag, decrease the medicinal liquid impact for mouth pipe junction, Prevent liquid leakage.

Specific embodiment

Embodiment 1

A kind of transfusion bag, including rectangular bag body 5, is medicinal liquid room 6 by the inside of rectangular bag body 5, at the one of rectangular bag body 5 minor face End marsupial body and mouth sealing of tube position 1, mouth pipe 2 is connected on rectangular bag body 5 by this welding position 1；At rectangular bag body 5 Top be provided with heat-sealing formed partition member 7, described partition member 7 be ellipse, the longer axis parallel of this ellipse in The width of rectangular bag body 5, and it is shorter than the width of rectangular bag body 5；Described partition member 7 is real weldering or rosin joint, by upper partition member 3 and lower partition member 4 form, and upper and lower two partition members formed ellipse partition member 7；

The distance on two long limits of end-point distances rectangular bag body 5 of the major axis of described oval partition member 7 is identical；

Mostly use, during transfusion bag vanning, the mode placed vertically or keep flat, often by from side or pressure effect above, by In transfusion bag material and mouth pipe material not exclusively as, welding between the two is also and insecure, it is easy to by outer masterpiece Separate with rear, cause the phenomenon of leakage to occur.According to statistics, the leakage position of more than 99% occurs in the weld part of transfusion bag and mouth pipe Position, and have oval partition member at the upper weld of transfusion bag, the instantaneous medicinal liquid gushed can be played certain cushioning effect, Decrease the impact to bag body Yu mouth pipe junction, it is therefore prevented that medicinal liquid is revealed；On the other hand, when transfusion, oval separation Parts are easy to medicinal liquid and are flowed at the mouth pipe of medicinal liquid room from both sides, it is therefore prevented that liquor residue, decrease medicinal liquid boil on the nape opposite the mouth pipe simultaneously and connect The pressure at place；

In sum, by arranging the partition member of ellipse in transfusion bag, decrease the medicinal liquid impact for mouth pipe junction, Prevent liquid leakage.
