Description

Clip type partition liquid bag

Technical Field

The application relates to a liquid bag, in particular to a partition type liquid bag.

Background

In medical treatment, the liquid bag contains liquid for infusion, which can be liquid medicine or nutrient solution. Sometimes several liquids are contained in a bag, but are not mixed during storage, but are merely mixed and shaken before use. The fluid bag shown in fig. 1 comprises

regions

1, 2, 3, the separation of fluid between adjacent regions being formed by pressing together the front and back sheets of the bag body. The partitioned liquid bag is convenient to produce, but is inconvenient to use, if the press-fit line is too tight, a nurse needs to strongly press liquid with air pressure when opening the press-fit line to open the press-fit line, and the bag body is often pressed and exploded in the process; if the line is too loose, and is squeezed during storage or transport, the liquids are prone to mixing accidentally.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present application aims to provide a clip type partitioned fluid bag in which partitioned areas are easily opened and adjacent areas are not communicated when pressed.

The utility model provides a clip type subregion liquid bag, it includes the bag body that comprises anter and back part, includes the drain nozzle on the bag body; at least one convex strip is transversely arranged on the rear piece of the bag body; the convex strip comprises a first surface and a second surface which are parallel to each other, and the width of the first surface is larger than that of the second surface; two ends of each convex strip are flush with two sides of the bag body;

a concave strip is detachably arranged on the front piece of the bag body corresponding to each convex strip; the length of the concave strip is not less than that of the convex strip corresponding to the concave strip; the contour of the inner circumferential surface of the concave strip corresponds to the contour of the outer circumferential surface of the convex strip; the concave strips are tightly buckled on the convex strips corresponding to the concave strips, and part of the front sheet and the rear sheet of the bag body is clamped between the convex strips and the concave strips, so that the liquid in the bag body can not flow through the part of the bag body clamped by the convex strips and the concave strips, and the bag body is divided into a plurality of areas, wherein each area is used for containing one type of liquid.

Preferably, the cross section of the convex strip is formed in an isosceles trapezoid.

Preferably, the recessed strip is formed with a protruding handle at a first end thereof.

Preferably, the concave strip is formed with a stopper at an inner side of the first end thereof.

Preferably, the extending direction of the liquid outlet nozzle is parallel to or perpendicular to the extending direction of the convex strip.

The liquid bag is divided into a plurality of areas through convex strips and concave strips which are matched front and back; when in use, the concave strip is only needed to be drawn out, which is very convenient. The convex strips are not easy to be separated from the concave strips due to compression during transportation, and the separation areas are not communicated accidentally.

Detailed Description

The clip-on partition liquid bag of the present application will be described in detail with reference to the accompanying drawings.

The clamping type partition liquid bag comprises a bag body consisting of a front sheet A and a rear sheet B, wherein the bag body comprises a liquid outlet nozzle; at least one convex strip 12 is transversely arranged on the back sheet B of the bag body; the convex strip 12 comprises a first surface and a second surface which are parallel to each other, and the width of the first surface is larger than that of the second surface; the two ends of each convex strip 12 are flush with the two sides of the bag body.

A concave strip 11 is detachably arranged on the front piece A of the bag body corresponding to each convex strip 12; the length of the concave strip 11 is not less than that of the convex strip 12 corresponding to the concave strip; the contour of the inner circumferential surface of the concave strip 11 corresponds to the contour of the outer circumferential surface of the convex strip; the concave strips 11 are tightly buckled on the convex strips 12 corresponding to the concave strips, and part of the front sheet A and the back sheet B of the bag body is clamped between the convex strips 12 and the concave strips 11, so that the liquid in the bag body can not flow through the part of the bag body clamped by the convex strips and the concave strips, thereby separating the bag body into a plurality of

areas

1, 2 and 3, wherein each area is used for containing one type of liquid.

The cross section of the convex strip 12 is formed into an isosceles trapezoid. The concave bar 11 is formed at a first end thereof with a protruding handle 11a to facilitate a pulling or pushing operation of the concave bar 11. The concave bar 11 is formed with a stopper 11b at an inner side of a first end thereof to abut on a first end of the convex bar when a second end of the concave bar 11 is completely flush with a second end of the picture bar 12. The extending direction of the liquid outlet nozzle is parallel or vertical to the extending direction of the convex strip 12. In fig. 2 and 3, the liquid outlet nozzle is parallel to the protruding strip 12, and may be positioned on the left or right side of fig. 2 and 3 and perpendicular to the protruding strip 12.

In this application, the bag body is the plastic bag, and concave strip and sand grip are the plastic strip, and concave strip and sand grip all have certain rigidity.

Although not shown in the drawings, corresponding to each divided area, the area may be individually formed with a dedicated pipe line according to a process or flow of filling the liquid, so as to facilitate the injection of the liquid into the divided area at a factory; the pipeline can be sealed by a heat sealing process after being filled with external liquid, or a joint can be arranged on the pipeline. The filling mode of the liquid in the partition area in the application is completely the same as that of the liquid in the existing partition liquid bag, so the detailed description is omitted.

When the device is used, the handle of the concave strip is held by hand, and the concave strip is pulled out from the convex strip, so that the separation state of adjacent areas formed by buckling the concave strip and the convex strip and separating is eliminated, and liquid can flow and be mixed. When the pressure is applied in the transportation process, the concave strips and the convex strips which are buckled together are difficult to open, so that the safety in the transportation process is ensured.
