Description

Technical Field

[0001] The utility model belongs to the technical field of drainage catheters, in particular to a drainage catheter kit. Background Art

[0002] Drainage catheters use the principle of siphon or negative pressure suction, are placed in the surgical area or body cavity of the human body and pass through the skin incision to the outside of the body, and guide the pus, exuded blood, tissue fluid and other fluids accumulated between human tissues or in the body cavity to the outside of the body to prevent fluid accumulation from causing postoperative infection. Ordinary drainage catheters are mainly used to drain gases and liquids in the body, such as digestive fluid, peritoneal fluid, pus and surgical incision exudates. Expelling these liquids to the outside of the body can reduce local pressure and adhesion, and promote wound healing. When using ordinary drainage tubes, it is necessary to place the spare items on the treatment cart and push them to the patient's bedside, and explain the work to the patient. The drainage catheter dedicated to the lacrimal duct may not be common in real life, and can be used as a long-term indwelling drainage tube. The front end of the metal probe of the lacrimal duct drainage tube is teardrop-shaped, and the smooth transition can reduce damage to the lacrimal duct, making it easy to hook and pull out the silicone rubber material from the nasal cavity, so it is used more frequently in clinical practice.

[0003] The Chinese authorized announcement number CN217187424U is a puncture drainage catheter kit. The puncture needle pre-punctures the cavity to be drained, removes the needle core, and uses the needle jacket as an injection channel to inject a small amount of contrast agent into the diseased area, thereby judging the accuracy of the puncture and analyzing the specific situation of the diseased area more clearly, so that when the guide wire, dilation tube and drainage tube are subsequently delivered to the diseased area, the position and shape of each component can be better controlled, reducing the risk of damage to the surrounding tissues of the diseased area, and being safer to use. However, if the patent uses puncture drainage in combination with drugs such as urokinase during treatment, there is a risk of causing secondary bleeding. The steps are relatively cumbersome, and the drainage catheter cannot meet the requirements of emergency surgery, reducing the practicality of the drainage catheter when in use. Therefore, we proposed a drainage catheter kit. Utility Model Content
