Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a chest drainage tube. Background Technology
[0002] Lung cancer is the leading cause of cancer-related morbidity and mortality worldwide. Surgery is currently the preferred treatment for lung cancer. During and after surgery, lung cancer patients usually need to have a chest tube placed. However, the chest tubes currently used in clinical practice are all single straight tubes, which cannot meet complex clinical requirements, such as pleural irrigation, injection of drugs into the pleural cavity, and the inability to adjust the angle of the chest tube according to the drainage site during surgery. This makes the operation of the chest tube inconvenient and may even cause discomfort and pain to patients during and after surgery. Utility Model Content
[0003] Purpose of the invention: In view of the defects and deficiencies of the existing technology, the purpose of this utility model is to provide a chest drainage tube, which uses a silicone main tube and inner delivery tube to reduce irritation to the affected area, and the shaped substrate can shape and bend the chest drainage tube to reduce the pressure and irritation of the affected area caused by the rebound of the chest tube, thereby reducing the patient's discomfort.
[0004] Technical Solution: To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a chest drainage tube, comprising a main chest tube, an inner infusion tube, a heparin cap, and a shaping substrate. Both the main chest tube and the inner infusion tube are made of silicone, and the inner infusion tube is disposed inside the main chest tube. The infusion end of the inner infusion tube extends out of the front end of the main chest tube, and the tail end of the inner infusion tube passes through the main chest tube, and the tail end of the inner infusion tube is provided with a heparin cap. The shaping substrate is disposed on the side wall of the main chest tube.
[0005] Preferably, the shaping substrate is a metal wire mesh skeleton or metal wire disposed in the side wall of the main chest tube.
[0006] Preferably, the shaping substrate is located inside the side wall of the main chest tube on the side away from the inner infusion tube.
[0007] Preferably, the front end of the main chest tube is provided with several side holes on its side wall.
[0008] Preferably, the tail end of the main chest tube is connected to a chest drainage bottle.
[0009] Beneficial effects: Compared with existing technologies, this invention uses a combined inner and outer tube structure made of silicone, which effectively solves the problems of irrigation and drug injection while reducing the discomfort of PVC tubes to patients. More importantly, the chest tube of this invention has a pre-embedded shaping substrate made of metal wire or metal wire mesh skeleton, which allows the angle of the chest tube to be adjusted according to the patient's actual situation, making it easier to fit the chest tube to the surgical site, reducing the pressure and irritation of the chest tube device on the pleura, thereby reducing patient discomfort.

[0014] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0015] like Figure 1 As shown, the chest drainage tube of this invention includes a main chest tube, an inner infusion tube, a heparin cap, and a shaping substrate. Both the main chest tube and the inner infusion tube are made of silicone. The main chest tube is used for irrigation of the affected area and is connected to a drainage bottle at its tail end for drainage and irrigation. The inner infusion tube is located inside one side of the main chest tube. On the other side of the main chest tube, a pre-embedded metal wire mesh framework or several metal wires facilitate bending of the chest tube to match and fix it to the position of the affected area, reducing the pressure and stimulation on the pleura that may occur during conventional chest tube insertion, thereby alleviating patient discomfort. The infusion end of the infusion tube extends beyond the front end of the main chest tube, and its tail end protrudes beyond the rear end of the main chest tube (exposed portion). A heparin cap is placed at the tail end of the inner infusion tube to control the drainage operation and prevent reflux. Two to five side holes can be opened on the side wall of the front end of the main chest tube to increase the efficiency of drug delivery, irrigation, and drainage. Its tail end is connected to the chest drainage bottle.
[0016] In this invention, the shaping substrate and the inner infusion tube are preferably positioned opposite each other within the main chest tube, providing space for bending operations and preventing compression of the inner infusion tube. When using this chest drainage tube, the surgeon bends the chest tube at multiple angles according to the patient's chest cavity characteristics to fix it within the chest cavity, ensuring the drainage tube conforms as closely as possible to the patient's needs. Figure 2 and 3 As shown, the chest tube of this invention can be bent at different angles as needed. The invention uses a silicone main tube and an inner delivery tube to reduce irritation to the affected area. While cleaning and draining through the main chest tube, medication is injected through the inner delivery tube to reduce the patient's pain.
[0017] The above description is only a partial embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
