[0025] In order for those skilled in the art to better understand the technical solutions of the application, the application will be clearly and completely described below in combination with the drawings in the embodiments of the application. However, the application can be implemented in many other ways different from the description below, and therefore, all other embodiments obtained by those skilled in the art based on the embodiments provided by the application without creative labor should belong to the protection scope of the application.

[0026] It should be noted that the terms "first", "second", "third", and the like in the claims, specification and drawings of this application are used for distinguishing between similar objects and are not necessarily used to describe a particular sequential or chronological order. Use of the terms so shall be interpreted to include a "reverse order" where appropriate unless explicitly stated otherwise. Also, the terms "comprising", "having", "including", and "containing" are to be construed as open-ended terms (i.e., meaning "including, but not limited to,") unless otherwise noted. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Further, to the extent that any definition or usage of a term in this document conflicts with the definition or usage of that term in a document incorporated by reference, the definition or usage contained in this document shall control.

[0027] Referring to Figures 1-4 The chest closed drainage barrel provided by the application comprises a drainage barrel body 1, a liquid seal pipe 2 is arranged in the drainage barrel body 1, one end of the liquid seal pipe 2 enters the barrel body through a drainage interface, and the other end of the liquid seal pipe 2 is connected with a chest drainage tube of a patient, a water slowing plate 3 is arranged in the drainage barrel body 1, one end of the liquid seal pipe 2 penetrates through the water slowing plate 3 and extends below the water slowing plate 3, the water slowing plate 3 is lower than the liquid level in the drainage barrel body 1, and a plurality of through holes 4 are formed in the water slowing plate 3, and the water slowing plate 3 is used for slowing down the flow speed of liquid in the drainage barrel body 1.

[0028] In the embodiment, the drainage barrel body 1 can be a drainage barrel that can be directly purchased, and the liquid seal pipe 2 can be a rigid pipe or a flexible pipe.

[0029] In the embodiment, the water slowing plate 3 can block the flow of liquid, so that the liquid flows slowly. In the technical solution of the application, the liquid below the water slowing plate 3 flows slowly, and when the drainage barrel body 1 is tilted, the liquid seal pipe 2 port below the water slowing plate 3 is separated from the liquid at a slower speed. Therefore, the liquid seal pipe 2 port below the water slowing plate 3 can not be separated from the liquid at the first time when the drainage barrel body 1 is tilted, so as to provide a certain time for the patient's family members or medical staff to hold up the drainage barrel body 1. Although the liquid seal pipe 2 port below the water slowing plate 3 is separated from the liquid at a slower speed, the technical solution of the application can delay the time, and the fault tolerance of the chest closed drainage barrel is higher than that of the existing drainage barrel body 1.

[0030] The application sets the water slowing plate 3, if the drainage bucket body 1 appears to dump, because the existence of the water slowing plate 3, can slow down the flow speed of the liquid below the water slowing plate 3, so, the liquid seal tube 2 end below the water slowing plate 3 is more not easy to separate from the liquid relative to the existing drainage bucket body 1, if dumping, under the action of the water slowing plate 3, can give more time to the medical staff and family to help the drainage bucket body 1, therefore, the closed thoracic drainage bucket of the application is safer to use.

[0031] In a specific embodiment, a T-shaped three-way ball valve 5 is further included; the first channel of the three-way ball valve 5 is in communication with the liquid seal tube 2, the second channel is in communication with the thoracic drainage tube, and the third channel is connected to the water inlet pipe 13; the three-way ball valve 5 can be in communication with the liquid seal and the thoracic drainage tube while closing the water inlet pipe 13; the three-way ball valve 5 can close the liquid seal tube 2 and the thoracic drainage tube; the three-way ball valve 5 can be in communication with the water inlet pipe 13 and the liquid seal tube 2 while closing the thoracic drainage tube.

[0032] In the embodiment, the T-shaped three-way ball valve 5 is set, which is a tool that can make the other two channels communicate and flexibly control the confluence or separation of the medium in the pipeline. In the application, during the preparation, the T-shaped three-way ball valve 5 is in communication with the water inlet pipe 13 and the liquid seal tube 2, and by injecting physiological saline into the water inlet pipe 13, it can be delivered to the drainage bucket body 1 through the water inlet pipe 13 and the liquid seal tube 2. When in communication with the drainage tube of the patient, the T-shaped three-way ball valve 5 can close the water inlet pipe 13 and communicate the drainage tube and the liquid seal tube 2. When it is necessary to stop the drainage halfway, the channel of the drainage tube and the liquid seal tube 2 can be directly closed. The scheme of the application can prolong the service life of the drainage tube compared with the existing scheme of closing the drainage tube with a metal clamp or a plastic clip.

[0033] It can be understood that in the technical scheme of the application, a plastic clip can also be prepared for selective use by doctors.

[0034] In order to further facilitate use, a mark can be provided on the T-shaped three-way ball valve 5, and when the switch of the T-shaped three-way ball valve 5 reaches the current mark, the expected communication state is reached.

[0035] In a specific embodiment, as shown in Figure 1 A pipe interface 6 is provided on the three-way ball valve 5, which is used to connect with the thoracic drainage tube of the patient. The pipe interface 6 is used to connect the thoracic drainage tube, which is conducive to improving the stability of the connection.

[0036] In one specific embodiment, an external thread 7 is provided on the outer side wall of the end of the water inlet pipe 13, and a threaded cap adapted to the external thread 7 at the end of the water inlet pipe 13 is also included. The threaded water inlet pipe 13 replaces the plug-in water inlet pipe 13. The water inlet pipe 13 with the thread and threaded cap has a more stable connection, and the threaded cap is less likely to fall off the water inlet pipe 13.

[0037] In one specific embodiment, the liquid seal pipe 2 includes a first section 8 and a second section 9; the first section 8 is a rigid pipe, which enters the barrel body through the drainage interface and extends to the bottom of the water-slowing plate 3; the second section 9 is a flexible hose, which is sleeved on the outside of the first section 8 and is sealed to the first section 8; a counterweight 10 is provided on the second section 9.

[0038] In this embodiment, see Figure 4 As shown, by dividing the liquid seal tube 2 into two parts, the first part 8 is rigidly connected to the water-slowing plate 3, making the connection more stable. On the other hand, the flexible second part 9 is arranged below the water-slowing plate 3. When the drainage bucket body 1 tilts, the position of the flexible second part 9 will change with the direction of water flow. At this time, the flexible second part is less likely to separate from the liquid, further improving the safety performance of the closed thoracic drainage bucket of this application.

[0039] In addition, this application sets a counterweight 10, which can be a pendant or other harmless material. This application does not limit the type of material. It should be noted that the density of the counterweight 10 needs to be greater than the density of the liquid in the closed thoracic drainage bucket. In this way, the counterweight 10 can provide the second part 9 with the downward movement power.

[0040] In one specific embodiment, a water outlet 11 is provided at the bottom of the drainage bucket body 1, and a threaded plug is provided with the water outlet 11. After the drainage is completed, it is necessary to drain the liquid in the drainage bucket body 1. At this time, it can be drained by opening the water outlet 11 at the bottom of the drainage bucket body 1. The operation is simple and convenient.

[0041] In one specific embodiment, a scale line 12 is provided on the drainage bucket body 1. This facilitates medical staff in observing the liquid level inside the drainage bucket body 1 and makes it easier for users to operate.

[0042] In this embodiment, the patients after thoracic surgery mostly need to stay thoracic closed drainage tube, which is used for draining pleural effusion and gas. The device is injected with physiological saline into the drainage barrel body 1 to the water level line, one end is connected with the thoracic closed drainage tube led out of the patient's chest wall, and the drainage tube and the liquid seal tube 2 are connected through the three-way ball valve 5. The drainage barrel body 1 is usually placed in a low position under the bed and hung on the beam under the bed by the hanging hook. The traditional water seal bottle is placed under the bed, and it is often knocked down by family members walking or moving the bed, causing the end of the water seal tube to be exposed to the air, which can easily cause the patient to have pneumothorax. The present application effectively delays the disadvantage that the water seal tube leaks liquid surface to contact air by setting the flexible second part 9 and the counterweight 10, and setting the water delay plate 3. In order to prevent the drainage liquid from flowing backward during the patient's examination and handling, the drainage tube can be closed through the three-way ball valve 5, and at the same time, in order to be safe, a plastic clamp can be added to the drainage tube to solve the problem that the current hemostatic forceps are easy to detach.

[0043] Although the present application is disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application should be subject to the scope defined by the claims of the present application.
