Description

Double-tube type transfusion bag ship-shaped connector

Technical Field

The utility model relates to a medical appliance, in particular to a medical infusion bag interface.

Background

An infusion bag is a disposable medical product used for intravenous infusion, and electrolytes and medicines in the infusion bag are infused into a human body through veins. The infusion bag structure includes the bag body that flexible material (adopting PP film usually) made and sets up the interface (adopting PP material preparation usually) that just has the transfer line in bag body open position, and the interface realizes sealedly through many strengthening ribs and the bag body welded fastening that set up around the base. However, the sealing performance between the bag body and the base is still insufficient, and during production, transportation and use, liquid leakage still occurs at the welding position, which easily causes medical accidents and needs to be further improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough among the above-mentioned background art, provide a double tube formula infusion bag ship type interface, this interface should have sealed effectual characteristics.

The technical scheme of the utility model is that:

double-tube type infusion bag ship type interface includes base and vertical infusion tube and the dosing pipe of fixing in the base bottom surface, its characterized in that: the two sides of the base are respectively provided with 3 reinforcing ribs which are horizontally arranged, and each reinforcing rib is also provided with a welding rib which protrudes to the side surface; the projection of the base on the horizontal plane is ship-shaped.

The base side comprises 6 parts, including two first sides that are parallel to the base length direction axis and two pairs of second sides that set up respectively at the base both ends and be certain angle crossing.

And the two ends of the base are provided with vertically arranged fins which extend outwards from the intersection of each pair of second side surfaces.

And the base is respectively provided with an infusion tube hole communicated with the infusion tube and a medicine adding tube hole communicated with the medicine adding tube.

The horizontal distance between the infusion tube and the medicine feeding tube is 15-25 mm.

The utility model has the advantages that:

the utility model discloses change conventional rhombus base into ship type base to add the welding muscle on the strengthening rib of base, not only shortened the width of base and the girth of base, greatly reduced bag body open-ended deformation degree and with the area of contact of base, the welding muscle is changeed and is melted on the strengthening rib moreover, has further improved the integration effect between base and the bag body, has reduced the risk of taking place the seepage after the welding.

Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

As shown in fig. 1, the double-tube transfusion bag boat-shaped interface comprises a base 1, a transfusion tube 2 and a medicine feeding tube 3. The infusion tube and the dosing tube are vertically fixed on the bottom surface of the base, the horizontal distance between the infusion tube and the dosing tube is 15-25mm, an infusion tube hole 1.3 communicated with the infusion tube and a dosing tube hole 1.4 communicated with the dosing tube are respectively arranged on the base, and the infusion tube hole and the dosing tube hole are communicated with the upper end surface and the lower end surface of the base. A blocking plate 3.1 is arranged in the dosing pipe.

As shown in fig. 2, the projection of the base on the horizontal plane is boat-shaped, the shape is formed by enclosing a plurality of planes, and the boat-shaped projection comprises two first side surfaces 1.1 and four second side surfaces 1.2, the first side surfaces are parallel to the longitudinal axis (the horizontal axis of fig. 2) of the base, the second side surfaces are pairwise arranged at two ends of the base, each pair of second side surfaces intersect with each other at a certain angle, and the intersecting position of each pair of second side surfaces is further provided with a fin 6 extending outwards.

As shown in fig. 1, 3 horizontally extending reinforcing ribs 4 are symmetrically arranged on both sides of the base in the width direction (vertical axis of fig. 2), the reinforcing ribs form a boat-shaped appearance of the base, each reinforcing rib is further provided with a welding rib 5 horizontally protruding towards the side, the welding rib is arranged in the middle of the reinforcing rib, two ends of the welding rib horizontally extend to fins at two ends, the width (the size in the vertical direction in fig. 1) of the welding rib is 0.1-0.3mm (preferably 0.2mm), and the height (the distance of the welding rib horizontally protruding from the surface of the reinforcing rib, and the size perpendicular to the paper surface in fig. 1) of the welding rib is 0.1-0.3mm (preferably 0.2 mm).

When infusion bag is produced, the base is wrapped by the opening of the bag body 7 (the PP film is used as the bag body), the base and the bag body are welded and fixed through hot melting welding, the structural design of the ship shape reduces the contact area of the bag body and the base, meanwhile, the welding ribs increase the fusion effect of the welding position, and the overall sealing performance is effectively guaranteed.
