Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a chest drainage device and a method for using the same. Background Art

[0002] It is known that patients receiving treatment in the respiratory department of a hospital often need chest drainage treatment; and the existing chest drainage method mainly adopts closed drainage, that is, closed chest drainage; this method uses a special silicone tube, plastic tube or surgical chest drainage tube as a drainage device, one end of which is inserted into the pleural cavity, and the other end is connected to a water seal bottle at a lower position than it, so as to continuously discharge the gas, pus, blood or other liquids in the chest cavity, and after the gas is discharged or the liquid in the chest cavity is collected, the lung tissue is reopened and the function is restored; the water seal bottle is the key to the closed drainage of this method, which not only ensures the outflow of gas and liquid, but also prevents the air from flowing back into the chest cavity due to negative pressure.

[0003] However, in actual use, the existing devices and methods for chest drainage have some problems: 1. The existing chest drainage bottle is large in size and is inconvenient to carry when multiple chest tubes are drained; and the water seal bottle used in the existing chest drainage device needs to be placed on the ground, so there is a risk of the water seal bottle tipping over during the transportation and movement of the patient, releasing pollutants and air into the chest cavity; 2. The traditional chest closed drainage bottle cannot accurately record the amount of chest drainage fluid and lacks collection measures; therefore, a chest drainage device and a method of use thereof are proposed as a further improvement.

[0010] Furthermore, the volume of the water seal device is no more than 100 ml, a scale is provided on the drainage bag, and the materials of the drainage bag and the water seal device are both set to be transparent materials.

[0011] Furthermore, the airway pipe is connected to the second section of the pipe body to form a Y-shaped pipe shape, and a guide piece is fixedly installed on the inner wall of the second section of the pipe body close to the airway pipe.

[0027] Technical effects and advantages of the present invention:

[0028] 1. Compared with the prior art, the gas-liquid separation is achieved by setting up a drainage bag and a water seal device. The drainage bag not only provides a collection function, but also can accurately record the amount of chest drainage. Compared with the conventional water seal bottle, the water seal device is smaller in size and moved up in position, so it is convenient to observe the water column fluctuation of the airway in the water seal device. The low-position drainage bag does not need to worry about tipping over even if it is on the ground, and the overall structure is easy to carry.

[0029] 2. Compared with the prior art, a one-way air intake device is provided, and a second one-way valve and a third one-way valve are utilized. When the resettable airbag is pressed, the air in the resettable airbag will pass through the third one-way valve and enter the second tube body along the air intake pipe; when the resettable airbag is reset by releasing the external force after being pressed, the air of the external environment will be sucked into the resettable airbag from the second one-way valve; repeatedly pressing the resettable airbag in this way will continuously press the air into the second tube body, and the second tube body will be closed in cooperation with the three-way valve, so that the gas that can be added will clear the second tube body, allowing foreign matter to enter the drainage bag, and the excess gas will be discharged from the water seal device along the airway, thus keeping the second tube body unobstructed; the conventional method of manually squeezing the chest tube when the tube is blocked is changed, thereby avoiding the pain of the patient caused by squeezing the chest tube.

[0030] 3. Compared with the prior art, the method for using the chest drainage device disclosed in the present invention creatively integrates the use of water seal bottle, drainage bag, three-way valve, air bag, Y-tube and one-way valve components into a whole, giving full play to the role of each component, thereby achieving the effect of easy carrying, convenient operation and easy observation; therefore, it is creative.
