Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a drainage device for thoracic surgery. Background Technology

[0002] Thoracic drainage is a treatment method that involves draining pus, blood, or fluid from the pleural cavity through puncture. It is mainly used for cases where there is fluid accumulation, blood accumulation, or abscess in the pleural cavity.

[0003] Patent CN222488309U discloses a thoracic drainage device for use in thoracic surgery. It consists of a drainage bottle, drainage tube, fixing needle, cleaning tube, valve, connector, cleaning needle, and sealing device. When the drainage tube becomes blocked, the cleaning needle is connected to the connector, and the valve is opened. The cleaning needle then injects a dissolving solution into the drainage tube through the connector, valve, and cleaning tube to dissolve the blood clots and pus. Aspiration is then performed to clear the blockage, ensuring smooth drainage. Simultaneously, the sealing device is activated to seal the end near the fixing needle, preventing the cleaning needle from affecting the patient when aspirating blockages from the drainage tube. Afterward, the valve is closed, and the sealing device is activated, allowing the drainage tube to continue smoothly for the patient's drainage.

[0004] However, in actual use, if the required dissolving solution cannot be found temporarily, the time spent searching may delay the removal of blood clots and pus, reduce the efficiency of the removal, and make it unsuitable for use. It is also dependent on the dissolving solution. Therefore, a drainage device for thoracic surgery is proposed. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0006] Therefore, one objective of this utility model is to provide a drainage device for thoracic surgery, which can use an air-intake balloon to continuously purge blood clots and pus, making it convenient to use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drainage device for thoracic surgery, comprising: a drainage bottle; a connecting tube, the connecting tube being connected to the drainage bottle and having an injection tube connected to it; a housing, the housing being connected to one end of the connecting tube, two rotating rods being rotatably connected inside the housing, a multi-port tube being fixedly connected inside the housing, a sphere being rotatably connected inside the multi-port tube, the sphere having a through hole inside, and one end of the rotating rods being fixedly connected to the sphere; and an air inlet bladder, the air inlet bladder being fixedly connected to the outside of the housing, one end of the air inlet bladder being connected to the inside of the multi-port tube.

[0008] Preferably, one end of the multi-port tube is connected to a needle.

[0009] Preferably, a ball valve is installed on the injection tube.

[0010] Preferably, the air intake airbag is made of silicone.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features a multi-port tube and an air inlet bladder. The air inlet bladder connects to the connecting tube via a through-hole. Pressing the air inlet bladder uses gas to impact blood clots and pus within the connecting tube, achieving a cleaning effect and allowing the blood clots and pus to flow into the drainage bottle. Alternatively, by opening the ball valve, a dissolving liquid can be injected into the connecting tube through the injection tube, making it easier to clean blood clots and pus. This invention achieves a cleaning method that, in addition to dissolving blockages with the injected dissolving liquid, continuously uses the air inlet bladder to propel the blood clots and pus with gas. It is convenient to use and reduces dependence on the dissolving liquid. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a drainage device for thoracic surgery, comprising: a drainage bottle 1; a connecting tube 2 connected to the drainage bottle 1, with an injection tube 6 connected to the connecting tube 2; a housing 3 connected to one end of the connecting tube 2, with two rotating rods 4 rotatably connected inside the housing 3, a multi-port tube 8 fixedly connected inside the housing 3, a ball 10 rotatably connected inside the multi-port tube 8, a through hole 11 opened inside the ball 10, and one end of the rotating rods 4 fixedly connected to the ball 10; and an air inlet 5 fixedly connected to the outside of the housing 3, with one end of the air inlet 5 connected to the inside of the multi-port tube 8, and one end of the multi-port tube 8 connected to a needle 9.

[0020] When blood clots and pus are present in the connecting tube 2 during use, the rotating rod 4 near the needle 9 is rotated to close the connection with the ball 10. Then, the rotating rod 4 near the drainage bottle 1 is opened to rotate the ball 10, thereby allowing the air inlet 5 to connect with the connecting tube 2 through the through hole 11. Pressing the air inlet 5 will cause the blood clots and pus in the connecting tube 2 to be impacted by gas to achieve a cleaning effect, allowing the blood clots and pus to flow into the drainage bottle 1.

[0021] Among them, a ball valve 7 is installed on the injection tube 6.

[0022] Alternatively, by opening the ball valve 7, dissolving liquid can be injected from the injection tube 6 into the connecting tube 2, making it easier to remove blood clots and pus.

[0023] When the air intake bladder 5 is not needed, rotate the ball 10 near the connecting tube 2 to connect it to the multi-port tube 8, and then turn the rotating rod 4 near the needle 9 to open the connection of the ball 10.

[0024] The air intake bladder 5 is made of silicone.

[0025] Working principle summary: When blood clots and pus are present in the connecting tube 2 during use, rotating the rotating rod 4 near the needle 9 causes the ball 10 to close the connection. Then, opening the rotating rod 4 near the drainage bottle 1 causes the ball 10 to rotate, thereby connecting the air inlet 5 to the connecting tube 2 through the through hole 11 and the multi-port tube 8. Pressing the air inlet 5 causes gas impact to clean the blood clots and pus in the connecting tube 2, allowing the blood clots and pus to flow into the drainage bottle 1. Alternatively, by opening the ball valve 7, dissolving liquid can be injected into the connecting tube 2 from the injection tube 6, making it easier to clean the blood clots and pus.

[0026] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
