Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a local puncture and irrigation drug injection device for gout. Background Technology

[0002] Knee joint lavage has significant therapeutic effects on a variety of common knee joint diseases, including suppurative arthritis, osteoarthritis, gouty arthritis, acute, chronic, or traumatic synovitis, and rheumatoid arthritis. Joint lavage can minimize bacterial counts, remove debris, loose bodies, and tophi, and clear various inflammatory mediators and immune complexes. By improving the local environment within the knee joint cavity, it alleviates pain, thereby reducing clinical symptoms and even achieving therapeutic effects. For acute synovitis and gouty arthritis, timely and effective knee joint lavage combined with local hydraulic anti-inflammatory treatment has achieved significant clinical results and is recognized both domestically and internationally.

[0003] To meet treatment needs, a device is required that can perform both flushing and drug administration. Utility Model Content

[0004] To address the aforementioned problems, a local puncture and irrigation drug injection device for gout is provided, aiming to solve the problems existing in the prior art.

[0005] The specific technical solution is as follows:

[0006] A local puncture and irrigation drug delivery device for gout includes a puncture needle and a connecting tube. The puncture needle is disposed at the lower end of the connecting tube. The puncture needle includes an outer puncture tube and an inner delivery tube. The lower end of the outer puncture tube is set as a pointed tip. The inner delivery tube is disposed in the outer puncture tube. An irrigation chamber is provided between the inner delivery tube and the outer puncture tube. The connecting tube is provided with an irrigation water chamber and a drug delivery chamber. The irrigation water chamber is connected to the irrigation chamber. The drug delivery chamber is connected to the inner cavity of the inner delivery tube.

[0007] The aforementioned local puncture and irrigation injection device for gout also has the following feature: the upper end of the inner infusion cylinder is flush with the upper end of the outer puncture cylinder, and the lower end of the inner infusion cylinder does not reach the inclined opening of the outer puncture cylinder.

[0008] The beneficial effects of the above scheme are: the lower end of the inner tube does not extend beyond the lower opening of the outer tube, thus avoiding the inner tube affecting the puncture effect when the outer tube is puncturing.

[0009] The aforementioned local puncture and irrigation injection device for gout also has the following features: the connecting tube includes an inner guide tube, an outer guide tube, and an annular chamber. The inner guide tube is disposed inside the outer guide tube, with an irrigation water chamber between them. The upper end of the irrigation water chamber is connected to the annular chamber, and an inlet is provided on the annular chamber. The upper end of the inner guide tube passes through the annular chamber, and an openable and closable opening is provided at the upper end of the inner guide tube.

[0010] The beneficial effects of the above scheme are as follows: the annular chamber is used to connect the flushing water chamber with the external flushing water input device. After flushing is completed, the medicine can be injected into the perforation site through the inner guide tube.

[0011] The aforementioned local puncture and irrigation drug delivery device for gout also has the feature that the upper opening of the inner guide tube is provided with a movable connection port for connecting to an external drug delivery device.

[0012] The beneficial effects of the above solution are: after rinsing, the movable connection port can be connected to the external drug delivery device to inject drugs into the puncture site.

[0013] In summary, the beneficial effects of this scheme are:

[0014] The local puncture, irrigation, and drug injection device for gout provided by this utility model features a two-layer structure for the puncture needle. The outer cavity is used to deliver the irrigation fluid, and the inner cavity is used to deliver the medication, allowing irrigation and drug injection to be completed with a single puncture. This device avoids the repeated damage to the patient caused by multiple punctures. Attached Figure Description
