Description

Technical Field

[0001] This utility model relates to the field of drainage bottle technology, specifically a modified single-cavity closed thoracic drainage bottle. Background Technology

[0002] Single-chamber closed thoracic drainage bottles are a commonly used traditional closed thoracic drainage tool in cardiothoracic surgery. They have the advantages of simple structure and low cost. The existing single-chamber closed thoracic drainage bottles are water-seal single-bottle drainage devices, which use the water seal principle to drain air and fluid from patients with pneumothorax and pleural effusion.

[0003] The single-chamber closed thoracic drainage bottle mainly consists of a bottle body, a water seal tube, a drainage tube interface, a fluid inlet, and a drainage tube. The bottle body has a 5cm diameter circular opening at the top, which is sealed with a cap. The cap has a pre-installed fluid inlet and a drainage tube interface. The drainage tube interface is integrated with the water seal tube, with the end of the water seal tube submerged in water to form a water seal, thus allowing drainage of pleural effusion and pneumothorax. However, the following drawbacks exist during use: Defect 1: Adding water seal solution is time-consuming and prone to overflow: In daily operation, 500ml of physiological saline needs to be poured into the bottle through the inlet to form a water seal before connecting the drainage bottle. Because the inlet diameter is only 1cm, adding solution is inconvenient. Although an inlet funnel is provided, the addition time is still long and overflow is common. Defect 2: Pouring drainage solution is inconvenient: When pouring drainage solution, the drainage tube must be clamped beforehand, the bottle cap opened, and the drainage solution poured out through the round opening at the top of the bottle. If the clamping process is missed, it can easily cause pneumothorax. Because the bottle cap and water seal tube are... The integrated design exposes the water seal tube when the cap is opened, which can easily lead to contamination of the water seal tube and thus the bottle cavity. Furthermore, since the filling port and the pouring port are actually the same outlet, the reverse pouring process can also easily contaminate the bottle cavity. Due to the excessively large diameter of the drainage fluid outlet (5cm), the drainage fluid can easily splash out during the pouring process, causing environmental pollution. The third defect is that the existing single-chamber closed chest drainage bottle does not have a one-way valve design. When the patient's chest cavity pressure changes, body position changes, or the chest drainage level is too high, the drainage fluid or gas in the bottle can easily flow back into the chest cavity through the water seal tube and drainage fluid interface, which can easily cause a feeling of backflow.

[0004] Therefore, it is necessary to propose an improved single-chamber closed thoracic drainage bottle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an improved single-chamber closed thoracic drainage bottle. It has the advantages of solving the problems of long filling time and inconvenience by optimizing the filling port design, reducing the risk of induced pneumothorax by adding a drainage tube sealing device, and increasing the drainage fluid discharge outlet design to enable unidirectional drainage and reduce the probability of contamination of the drainage bottle and the environment. It solves the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a modified single-chamber closed thoracic drainage bottle, comprising: The bottle opening is installed at the middle of the upper surface of the drainage bottle, and a drainage tube is installed on one side of the bottle opening; A water seal pipe is installed at the lower end of the drainage tube, and a one-way valve is installed at the upper end of the drainage tube. A bottle cap is connected to the outer surface of the bottle mouth. Four sets of equidistant sliding grooves are opened on the inner side wall of the bottle cap. The four sets of sliding grooves are formed by annular grooves. A locking block is installed at equal intervals on the outer surface of the bottle mouth. The inside of the sliding groove is movably connected to the outer surface of the locking block. The outer surface of the locking block is engaged with the inside of the annular groove. Four sets of elastic columns are installed at equal intervals on the top inside of the bottle cap. A hollow sealing gasket is fixedly connected to the lower end of the four sets of elastic columns. The lower surface of the hollow sealing gasket is in contact with the upper surface of the bottle mouth. An exhaust pipe is installed in the middle of the bottle cap.

[0007] Preferably, a discharge tube is installed at the lower end of one side of the drainage bottle, and both the discharge tube and the drainage tube are equipped with clips.

[0008] Preferably, the inside of the drainage bottle is pre-set with a water seal liquid level, and the lower end of the water seal tube is below the water seal liquid level.

[0009] Preferably, the inner width of the groove is the same as the outer width of the block, and the height of the annular groove is the same as the height of the block.

[0010] Preferably, the outer surface of the exhaust pipe is fixedly connected to the inside of the bottle cap, and the lower end of the outer surface of the exhaust pipe is fitted to the inside of the hollow sealing gasket.

[0011] Preferably, the diameter of the hollow sealing gasket is the same as the diameter of the top of the bottle opening.

[0012] Preferably, a U-shaped block is installed on the side of the drainage bottle, and a shaft connecting block is rotatably connected to the other side of the U-shaped block. The shaft end of the shaft connecting block is rotatably connected to the inside of the U-shaped block. A rubber pad is sleeved at the contact point between the shaft end of the shaft connecting block and the inside of the U-shaped block. A semi-circular protective shell is fixedly connected to the other side of the shaft connecting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This improved single-chamber closed thoracic drainage bottle, while maintaining the original drainage bottle design, features a rotating snap-on cap at the bottle opening, making the connection between the cap and the bottle opening more convenient and facilitating the addition of water seal fluid. A pre-set clip on the drainage tube allows for easy closure at any time, ensuring a sealed thoracic cavity. A one-way valve on the drainage tube prevents backflow of drainage fluid or gas due to changes in the patient's thoracic cavity pressure, thus preventing retrograde infection. An additional drain tube on the side of the drainage bottle changes the original pouring method from the bottle opening, creating a one-way drainage system and avoiding potential retrograde infection and environmental contamination during pouring.
