Description

Novel 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

The infusion bag is a disposable medical article for intravenous infusion, and needs to meet the requirements of no toxicity, no peculiar smell, good strength, scratch resistance, stable performance and the like so as to ensure that the electrolyte and the medicine in the infusion bag can be safely infused into a human body in an intravenous infusion mode. Infusion bag structure includes the bag body that flexible material made (adopts PP film preparation usually) and sets up the interface that has the transfer line at bag body open position (adopts PP material preparation usually), the interface is sealed through many strengthening ribs and bag body welded fastening realization that set up around the base, still be equipped with transfer line and dosing pipe on the base, set up baffler 3.1 and plug 8 (as shown in figure 8 and figure 9) usually in the dosing pipe, the plug is used for blockking that medicine oozes from the dosing pipe in the bag body, the baffler is used for blockking that the plug from adding the dosing pipe endwise slip (the dosing pipe inner wall is equipped with throat chucking plug), the open position that adds the dosing pipe still need cover pad 7 and cover the plug. When intravenous infusion is carried out, electrolyte and medicine in the bag body are discharged through an infusion tube, and when medicine is added, the medicine is sucked by using the needle cylinder and inserted into the medicine adding tube to inject the medicine into the bag body. However, the prior infusion bag has the following defects: 1. the sealing performance between the bag body and the interface base is still to be improved, and liquid leakage can occur at the welding position with a certain probability in the production, transportation and use processes; 2. the sticking film covering the rubber plug is needed to be torn off when the transfusion is carried out, so that the rubber plug can be pulled out of the medicine adding pipe along with the situation, and the rubber plug can be pulled out when the syringe is pulled out after the medicine is added by using the syringe.

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 novel 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.

The chemical feeding pipe is internally provided with a blocking plate 3.1, the outer circumferential surface of the bottom end of the chemical feeding pipe is provided with a boss 3.2, the bottom surface of the boss is a conical surface, and the bottom surface of the boss is also provided with a vertically and downwardly extending extension pipe 3.3. The boss has an outer diameter of 11-13mm (preferably 12mm) and a height of 6-7mm (preferably 6.5 mm). The outer diameter of the extension pipe is smaller than that of the boss, the outer diameter of the extension pipe is 9-10mm (preferably 10mm) and the height of the extension pipe is 1.5-2.0mm (preferably 1.8 mm).

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 the 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 in the direction perpendicular to the paper surface in fig. 1) of the welding rib is 0.1-0.3mm (preferably 0.2 mm).
