Description

Technical Field

[0001] The utility model belongs to the technical field of infusion sets, and in particular relates to an extendable parenteral nutrition infusion set. Background Art

[0002] Infusion sets are commonly used medical consumables in clinical practice, that is, they can use the principles of atmospheric pressure and liquid static pressure to inject large amounts of sterile liquids, electrolytes, and drugs into the body through veins. Their scope of action includes aspects such as parenteral infusion, nutritional support, and medication therapy. Since critically ill patients are in a critical condition and have lost consciousness, enteral nutrition solutions have become the preferred option to ensure daily nutritional needs. At present, infusion sets are used clinically to infuse nutrient solutions, but the length of the infusion sets is not long. When turning over and performing rehabilitation training for critically ill patients, the infusion set is easily caused to fall off due to the insufficient length of the infusion set. In severe cases, it can cause the gastric tube and nasointestinal tube to come out, resulting in an increase in the rate of unplanned extubation and the rate of secondary catheterization for patients. In view of this, the present utility model is specially proposed. Utility Model Content

One end of the silicone hose 6 is connected to the other end of the lower infusion tube 4 through the connector 5 for extending the infusion pipeline. One end of the catheter 7 is sleeved on the outside of the other end of the silicone hose 6, and the other end of the catheter 7 is connected to a tapered tube 8 for diverting and extending the pipeline.

[0029] Specifically, the flow-stop clamp 2 includes a clamp body 21, a through hole 22 is provided in the middle of one end of the clamp body 21, the through hole 22 is connected with the upper infusion tube 1, a slot 23 is provided inside the clamp body 21, a plug plate 24 is inserted inside the slot 23, the plug plate 24 can press the upper infusion tube 1 to stop the flow, an elastic card plate 25 is fixed to the end of the plug plate 24 away from the slot 23, the elastic card plate 25 is set to a U-shaped structure, and both sides are set to elastic structures, notches 56 are provided on both sides of one end of the clamp body 21, the notch 56 is adapted to the two ends of the elastic card plate 25, and the elastic card plate 25 cooperates with the notch 56 to limit the plug plate 24, so that the plug plate 24 can stably squeeze the upper infusion tube 1 to ensure continuous flow stopping.

[0030] More specifically, the connector 5 includes a connecting sleeve 51 fixed to the outside of one end of the lower infusion tube 4, and one end of the connecting sleeve 51 is fixed with a plurality of arc-shaped clamping plates 52 distributed in a circular array. The connector 5 also includes a connecting tube 53 fixed to one end of the silicone hose 6, and one end of the connecting tube 53 is inserted into the interior of the connecting sleeve 51. A sealing ring 54 is bonded to one end of the connecting tube 53, and the sealing ring 54 plays a sealing role to prevent air from entering the infusion tube. An annular stopper 55 is fixed to the outside of the other end of the connecting tube 53, and a plurality of notches 56 distributed in a circular array are provided on the circumference of the annular stopper 55, and the notches 56 are adapted to the arc-shaped clamping plate 52, and the arc-shaped clamping plate 52 cooperates with the block to play a limiting role, thereby stably limiting the connecting tube 53 and the connecting sleeve 51, thereby stably connecting the lower infusion tube 4 and the silicone catheter 7 and will not easily loosen.

[0032] When the flow-stop clamp 2 stops the flow, it presses the elastic card plate 25, and the elastic card plate 25 drives the plug plate 24 to move into the slot 23 until the plug plate 24 squeezes the upper infusion tube 1 and stops the flow of the upper infusion tube 1. At this time, the two ends of the elastic card plate 25 are inserted into the card grooves 26 on both sides of the clamp body 21, which plays a limiting role and prevents the plug plate 24 from returning, so that the plug plate 24 can stably stop the flow of the upper infusion tube 1.

[0033] When the connecting piece 5 is connected, first insert the connecting pipe 53 into the connecting sleeve 51 until the arc-shaped clamping plate 52 passes through the notch 56 on the stopper and is clamped on the back of the stopper, which plays a limiting role. The notch 56 limits the arc-shaped clamping plate 52 to prevent the arc-shaped clamping plate 52 from rotating at will, thereby preventing the connecting pipe 53 and the connecting sleeve 51 from rotating relative to each other.
