[0002] Cardiovascular drainage is a method of placing one end of a drainage tube into the chest cavity, while the other end is connected to a water-seal bottle at a lower position or a drainage bottle connected to a negative pressure device, so as to discharge gas or collect fluid in the chest cavity, allowing the lung tissue to reopen and restore function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases.

[0003] Existing negative pressure drainage bottles usually include a bottle body, a bottle cap and a drainage tube. The bottle cap is usually provided with two interfaces, namely a liquid inlet interface and a negative pressure interface. During operation, one end of the drainage tube is inserted into the liquid inlet of the bottle cap, and the other end of the drainage tube is placed on the drainage position. The negative pressure interface on the bottle cap is connected to a negative pressure suction device through a negative pressure connecting tube, and negative pressure is generated in the bottle body through the negative pressure suction device, thereby drawing the drainage fluid into the bottle body.

[0004] However, when the patient has a large amount of pleural effusion, the negative pressure drainage bottle is easily filled up.

DETAILED DESCRIPTION

[0029] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0030] Please also read Figure 1-Figure 5 , this embodiment provides a drainage device for effusion, including a fixed tube 1, a diversion assembly 2, a diversion bottle 11, a first elastic support member 12, a sealing assembly 3, a connecting plate 13 and a diversion bottle 14;

[0031] The guide assembly 2 is arranged on the fixed tube 1, and the guide bottle 11 can be raised and lowered on the guide assembly 2, and is connected to the guide assembly 2 through the first elastic support member 12; it should be understood that the first elastic support member 12 can support the guide bottle 11 so that it can maintain a fixed height before the accumulated fluid flows into it. When the guide bottle 11 flows into the accumulated fluid, the guide bottle 11 will descend and press down the first elastic support member 12, and the first elastic support member 12 is preferably a spring.

[0032] A diversion hole 211 is provided on the diversion component 2, the connecting plate 13 is provided on the fixed tube 1, and the diversion bottle 14 is provided on the connecting plate 13, and the opening of the diversion bottle 14 is opposite to the diversion hole 211; it should be understood that the connecting plate 13 is lower than the diversion component 2, and the side of the fixed tube 1 is preferably provided with an opening, through which the diversion bottle 14 can be placed or taken.

[0033] A diversion port 111 is provided at the bottom of the diversion bottle 11. The closing component 3 is elastic and slidably provided on the diversion bottle 11. The closing component 3 can close the diversion port 111. The descent of the diversion bottle 11 can cause the closing component 3 to squeeze the diversion component 2 to open the diversion port 111, and the diversion port 111 and the diversion hole 211 are opposite to each other.

[0034] That is to say, one end of the two ends of the diversion hole 211 is opposite to the opening of the diversion bottle 14, and the other end is opposite to the diversion port 111 at the bottom of the diversion bottle 11. After the diversion bottle 11 starts to flow into the accumulated liquid, the diversion bottle 11 gradually descends. After the diversion bottle 11 descends to a certain height, the diversion component 2 squeezes the closing component 3 to make the closing component 3 slide to open the diversion port 111. After the diversion port 111 is opened, the accumulated liquid in the diversion bottle 11 flows from the diversion port 111 through the diversion groove into the diversion bottle 14. When the diversion liquid in the diversion bottle 11 is reduced, the weight of the diversion bottle 11 is reduced and it rises under the action of the first elastic support member. The closing component 3 away from the diversion component 2 is reset and the closing port is closed again under the action of its own elasticity.

[0035] In the present application, when the accumulated liquid in the guide bottle 11 reaches a certain weight, the guide port 111 at the bottom of the guide bottle 11 can be opened, and the accumulated liquid can flow into the diversion bottle 14, so as to avoid excessive accumulation of liquid in the guide bottle 11 and the need to repeatedly replace the guide bottle 11, thereby reducing the cumbersome operations required for replacing the guide bottle 11, such as inserting the guide tube into the new guide bottle 11.

[0036] In other schemes, the flow guide assembly 2 includes a flow guide plate 21, a limiting tube 22 and an extrusion boss 23; the flow guide plate 21 is fixed on the fixed tube 1, a flow guide hole 211 is provided on the flow guide plate 21, the limiting tube 22 is fixed on the flow guide plate 21, the limiting tube 22 is fixed on the flow guide plate 21, the flow guide bottle 11 can be raised and lowered in the limiting tube 22, and is connected to the flow guide plate 21 through the first elastic support 12; the extrusion boss 23 is fixed on the flow guide plate 21, and can squeeze the closure assembly 3 to slide. Specifically, the flow guide bottle 11 is a square bottle, the limiting tube 22 is a square tube, one end of the flow guide hole 211 is located in the limiting tube 22, after the flow guide bottle 11 is pressed down and the flow guide port 111 is opened, the accumulated liquid flows into the limiting tube 22 through the flow guide port 111, and then flows into the diversion bottle 14 through the flow guide hole 211, and preferably, the flow guide hole 211 is an inverted Z-shaped.

[0037] In other embodiments, the closing assembly 3 includes a closing plate 31, a wedge 32, an elastic connector 33 and a closing fixing plate 34; the closing plate 31 is slidably connected to the bottom of the guide bottle 11, and is connected to the closing fixing plate 34 through an elastic support member, the closing fixing plate 34 is fixed to the bottom of the guide bottle 11, and the wedge 32 is fixed to one end of the closing plate 31 close to the guide plate 21. It should be understood that the closing plate 31 can close the guide port 111, and the extrusion boss 23 can squeeze the wedge 32 when the closing plate 31 is pressed down, so that the closing plate 31 slides and opens the guide port 111.

[0038] In other schemes, a bottom plate 4, a limit assembly 5, a drive assembly 6, a second elastic support member 7, a feed pipe 8 and an arc-shaped baffle plate 9 are also provided; the bottom plate 4 is fixed in the fixed tube 1, and the top end of the bottom plate 4 is connected to the connecting plate 13 through the second elastic support member 7, and the connecting plate 13 can be raised and lowered and slidably connected in the fixed tube 1; the diverter bottle 14 is equidistantly arranged on the connecting plate 13, and the arc-shaped baffle plate 9 is rotatably arranged on the diverter plate, and the two ends of the arc-shaped baffle plate 9 are respectively abutted against the open side of the diverter bottle 14, and can close the guide hole 211; that is, the rotation of the diverter bottle 14 drives the arc-shaped baffle plate 9 to rotate, and closes the guide hole 211 in turn.

[0039] The limit assembly 5 is rotatably arranged on the bottom plate 4, and passes through the connecting plate 13 to frame each diverter bottle 14. The feed pipe 8 is fixed in the fixed pipe 1, and passes through the bottom plate 4 and the connecting plate 13 respectively. The rotation of the limit assembly 5 can push the diverter bottle 14 into the feed pipe 8 in sequence. After the bottom of the diverter bottle 14 loses support, it will fall into the feed pipe 8. The driving assembly 6 is arranged on the bottom plate 4, and can drive the limit assembly 5 to rotate. The driving assembly 6 is controlled by the touch switch 65 on the bottom plate 4, and the downward pressure of the connecting plate 13 can squeeze the touch switch 65.

[0040] That is, when there is too much liquid accumulated in the diverter bottle 14, the connecting plate 13 will be pressed down, and the touch switch 65 will be squeezed to rotate the limit assembly 5. The diverter bottle 14 with too much liquid accumulated will rotate to the discharge pipe 8 through the rotation of the limit assembly 5. The next diverter bottle 14 will rotate to the bottom of the guide hole 211. The diverter bottle 14 on the discharge pipe 8 will fall down after losing the support of the connecting plate 13. The connecting plate 13 will rise again and reset due to the elastic force of the second elastic support member 7 after losing the heavy pressure. Specifically, except for the diverter bottles 14 at the first and last ends, the adjacent diverter bottles 14 are placed at equal angles and equal intervals.

[0041] With this structure, when a single diverter bottle 14 stores too much fluid, a new diverter bottle 14 can be automatically replaced, thus eliminating the need for replacement operations.

[0042] In other embodiments, the limiting assembly 5 includes a rotating shaft 51, a connecting rod 52 and a limiting frame 53; the rotating shaft 51 is rotatably connected to the bottom plate 4 and passes through the connecting plate 13, one end of the connecting rod 52 is fixedly connected to the rotating shaft 51, and the other end is fixedly connected to the limiting frame 53, and the limiting frame 53 has a diverter bottle 14 built in. It should be understood that the connecting rod 52, the fixing frame and the diverter bottle 14 correspond one to one. Specifically.

[0043] In other embodiments, the limiting frame 53 is an arc frame. Setting it as an arc frame can facilitate the horizontal insertion of the diverter bottle 14. Specifically, the arc frame is elastic and fits the outer ring of the diverter bottle 14. It can be preferably slightly larger than the diverter bottle 14.

[0044] In other schemes, the rotating shaft 51 is also coaxially fixed to the groove wheel 54, and the driving assembly 6 includes a motor 61, a rotating disk 62, an arc-shaped boss 63 and a toggle column 64; the motor 61 is fixed to the bottom plate 4, the rotating disk 62 is coaxially fixed to the output shaft of the motor 61, and the toggle column 64 is eccentrically fixed to the rotating disk 62 and can drive the groove wheel 54 to rotate; the arc-shaped boss 63 is coaxially fixed to the rotating disk 62 and can limit the rotation of the groove wheel 54 within the rotation gap of the groove wheel 54. Through this structure, the rotating shaft 51 can be rotated intermittently, giving the diversion bottle 14 with too much fluid accumulation enough time to fall and the second elastic support member 7 enough time to reset.

[0045] In other embodiments, a switchable closed door is also provided on the feed pipe 8. The split bottle 14 can be conveniently removed by switching the closed door.

[0046] The above-mentioned fluid drainage device can automatically guide the accumulated fluid into the diversion bottle after the guide bottle is filled with sufficient accumulated fluid, thereby eliminating the operation of replacing the guide bottle.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
