[0001] The utility model belongs to the technical field of drainage bottles, in particular to a multifunctional drainage bottle. Background Art

[0002] A drainage bottle is a device used to guide, collect and store fluid. It usually consists of a container or bottle with a large opening and a connecting pipe to control the flow of fluid in and out of the bottle. It is used for closed chest drainage. One end of the drainage tube is placed in the chest cavity, and the other end is connected to a water seal bottle at a lower position to discharge gas or collect fluid in the chest cavity, so that the lung tissue can reopen and restore function.

[0003] Among them, after searching, it was found that there is an application number CN202120077003.0, which discloses a multifunctional drainage bottle, including a bottle body, a three-way pipe connected to the upper side of the bottle body through a liquid inlet pipe, and the left and right ends of the three-way pipe are connected to joints through connecting pipes. A joint and a switch clamp are set, which is convenient for docking the drainage tube with the bottle body, reducing the operation steps. A one-way valve and a piston that can be moved left and right are provided, which are convenient for generating negative pressure inside the bottle body, reducing the volume of the drainage device, and reducing the cost of drainage. A baffle that can be moved left and right is provided to avoid the phenomenon of repeated disassembly and assembly of the joint to dump the accumulated liquid, and avoid the leakage of the accumulated liquid and repeated contamination caused by the disassembly and assembly of the joint. An observation plate that can be moved up and down is provided to facilitate the observation of the strength of the negative pressure inside the bottle body, and avoid the phenomenon that the negative pressure inside the bottle body is too small and the drainage fluid cannot be discharged. This has the advantages of simple structure, convenient operation, novel conception and strong practicality.

[0004] However, after research, it was found that: when using the drainage bottle, the piston needs to be moved left and right to generate negative pressure inside the bottle body, which is not convenient to use. When moving the drainage bottle, the drainage tube should be clamped for safety. The drainage bottle does not have a structure for clamping the drainage tube, and the patient needs to clamp the drainage tube manually. If the patient accidentally lets go, it is easy to cause air leakage, which is not safe to use. Therefore, a new device is provided to solve this problem. Utility Model Content

The top of the drainage bottle 1 is provided with an exhaust port 103, and a one-way valve B1031 is installed at the outlet of the exhaust port 103. The surface of the drainage bottle 1 is provided with an integrated pressing area 104, and the pressing area 104 is provided in a semicircular arc shape, and the pressing area 104 is made of soft PVC. A connecting groove 1042 is symmetrically fixedly installed at a side of the drainage bottle 1 corresponding to the pressing area 104, and a pressing plate 1041 is elastically connected to the inside of the two connecting grooves 1042, and the shape of the pressing plate 1041 matches the shape of the pressing area 104, and the pressing plate 1041 and the pressing area 104 are bonded together;

[0023] The staff presses the pressing plate 1041, and the pressing area 104 is deformed by the pressing plate 104, which reduces the internal volume of the pressing area 104 and increases the water seal level inside the drainage bottle 1, squeezing the gas inside the pressing area 104 out from the exhaust port 103. The one-way valve B1031 can prevent external air from entering the drainage bottle 1. The staff then releases the pressing plate 1041, and the spring force causes the pressing plate 1041 to reset close to the connecting groove 1042. The pressing plate 1041 also drives the pressing area 104 to reset, so that the volume of the drainage bottle 1 is restored. At this time, the interior of the drainage bottle 1 is in a negative pressure state, and the effusion or gas in the patient's chest cavity is sucked into the drainage bottle 1 through the drainage tube 101 for collection.

[0024] Reference Figure 1 , 3 In this embodiment, a one-way valve A1012 is installed at the outlet of the drainage tube 101, a connecting sleeve 1011 matching with the interface 102 is nested outside the drainage tube 101, and an internal thread matching with the external thread of the interface 102 is arranged inside the connecting sleeve 1011, and the connecting sleeve 1011 is sealed and threadedly connected with the interface 102, and a drainage port 106 is arranged on one side of the bottom of the drainage bottle 1, and a sealing cover 1061 is threadedly connected at the outlet of the drainage port 106;

[0028] Working principle: First, add 8-12 ml of normal saline into the drainage bottle 1 from the interface 102, then extend the outlet of the drainage tube 101 into the water seal of the drainage bottle 1, and screw the connecting sleeve 1011 on the interface 102 to achieve the purpose of connecting the drainage tube 101 to the drainage bottle 1. Connect the drainage tube 101 to the patient's chest cavity, and then the staff presses the pressing plate 1041. The pressing plate 1041 presses the pressing area 104 to deform, so that the internal volume of the pressing area 104 becomes smaller, and the water seal liquid level inside the drainage bottle 1 rises, and the gas inside the pressing area 104 is squeezed out from the exhaust port 103. The one-way valve B1031 can prevent external air from entering the drainage bottle 1, and then loosen it. Open the pressure plate 1041, and under the action of the spring force, the pressure plate 1041 is reset close to the connecting groove 1042. The pressure plate 1041 also drives the pressing area 104 to reset, so that the volume of the drainage bottle 1 is restored. At this time, the interior of the drainage bottle 1 is in a negative pressure state, and the effusion or gas in the patient's chest cavity is sucked into the drainage bottle 1 through the drainage tube 101 for collection. When the patient needs to move, the drainage tube 101 is folded back, and the opening clamp 1071 is removed from the connecting plate 107 and clamped on the folded part of the drainage tube 101 to close the drainage tube 101.
