Description

Technical Field

[0001] The utility model relates to the technical field of pleural effusion drainage, in particular to a minimally invasive pleural effusion drainage device. Background Art

[0002] For patients with pleural effusion (or pneumothorax), pleural effusion or gas is extracted through thoracentesis for diagnosis and treatment of the disease. After the puncture, a sterile chest drainage tube and drainage bottle are connected to drain the pleural effusion or gas in the patient's body. Since the chest drainage tube can only be removed 2 to 3 days after the operation, the patient still needs a chest drainage tube to drain the pleural effusion after the operation;

[0003] Current pleural effusion drainage devices generally include a fluid storage bag and a drainage tube. The drainage tube is directly introduced into the drainage port of the patient's chest for drainage, and the fluid storage bag is used to store the drainage fluid. However, when the existing pleural effusion drainage device is draining, the patient needs to keep the drainage tube in a fixed position when getting out of bed and walking. During the walking process, the drainage tube is easily twisted due to the patient taking the fluid storage bag, which can easily cause the drainage tube to move out of the patient's chest. For this reason, we propose a minimally invasive pleural effusion drainage device. Utility Model Content

[0004] The purpose of the utility model is to provide a minimally invasive pleural effusion drainage device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a minimally invasive pleural effusion drainage device, comprising a liquid storage bag, a drainage tube, a connecting mechanism, a drainage tube and a chest connecting piece, the top of the liquid storage bag is connected to the drainage tube, and the end of the drainage tube is provided with a connecting mechanism, the drainage tube is connected to the drainage tube through the connecting mechanism, a chest connecting piece is installed on the outside of the drainage tube, and an adhesive piece is provided on the side of the chest connecting piece away from the connecting mechanism.

[0006] Preferably, the connecting mechanism comprises a connecting plate, one end of the drainage tube away from the liquid storage bag is rotatably connected to the bottom of the connecting plate, a connecting tube is integrally provided on the top of the connecting plate, and the bottom end of the drainage tube is clamped in the connecting tube.

[0007] Preferably, a card slot is symmetrically opened on the top of the connecting tube, a support rod is symmetrically fixedly connected to the outer side of the bottom end of the drainage tube, the support rod is clamped in the card slot, a fixing rod is symmetrically fixedly connected to the outer side of the connecting plate, and a rubber band is arranged on the outer side of the fixing rod, and the fixing rod and the support rod are connected by the rubber band.

[0008] Preferably, connecting ropes are symmetrically fixed to the side walls of the chest connecting piece, and ends of the connecting ropes are fixedly connected to the connecting plates.

[0009] Preferably, a sealing ring is provided on the inner wall of the connecting tube at one end of the connecting plate, and the drainage tube is in contact with the sealing ring.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model arranges the guide tube installed on the liquid storage bag and the connecting plate to be rotatably connected. During the drainage process, when the patient takes the liquid storage bag while walking or pours out the liquid in the liquid storage bag, the guide tube can adjust its position by rotating at the bottom of the connecting plate. During the placement of the liquid storage bag, there is no need to consider whether the drainage tube is twisted, which is more convenient to use and solves the problem of the drainage tube being detached from the patient's chest cavity due to twisting.
