Description

An anti-reflux drainage tube that can be cleaned in use

technical field

The utility model relates to a medical device, in particular to an anti-reflux drainage tube which can be cleaned during use.

Background technique

Postoperative drainage is an important preventive measure to avoid fluid and blood accumulation in the operation area and prevent poor postoperative wound healing. At present, the clinical drainage method mostly adopts negative pressure drainage, that is, the drainage tube is connected to the lower part of the operation area through a negative pressure device, so as to facilitate the outflow of fluid. However, as the pressure of the negative pressure device gradually weakens, and the drainage tube is pulled and folded by external forces, the drainage fluid may flow back into the operation area, resulting in the possibility of retrograde infection in the operation area. Bacteria are easy to breed in the drainage tube, and the drainage tube is connected to the operation area during use, so it is difficult to clean the drainage tube during use, so it is easy to cause the operation area to be infected by the breeding bacteria.

Utility model content

In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an anti-reflux drainage tube that can be cleaned during use, and the drainage tube can effectively avoid the possibility of surgical area infection during the use of the drainage tube.

The technical scheme adopted in the utility model is:

An anti-reflux drainage tube that can be cleaned in use, including a tube body, the tube body is provided with a one-way valve, and the one-way valve divides the tube body into a front tube section on the side of the liquid inlet and a liquid outlet The rear pipe section on one side is provided with a flushing device connected to the rear pipe section.

As a further improvement of the above technical solution, the one-way valve includes 2 or 3 valves with openings facing the liquid outlet of the tube body and equally divided.

As a further improvement of the above technical solution, the flushing device includes a flushing tube connected to the rear pipe section, and the flushing pipe is connected to the front end of the rear pipe section close to the one-way valve.

As a further improvement of the above technical solution, the flushing pipe is provided with a flushing valve.

As a further improvement of the above technical solution, a piston conveyor is installed at the end of the flushing pipe.

The beneficial effects of the utility model are: the utility model is provided with a one-way valve in the tube body, so that the liquid inside the operation area can flow out smoothly, and can prevent the external liquid from regurgitating, avoiding the possibility of retrograde infection in the operation area. The flushing device is convenient for the external disinfectant to flush the drainage tube, so as to avoid the possibility of bacteria growing in the drainage tube from infecting the operation area.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the schematic diagram of the use state of the utility model;

Fig. 3 is a schematic diagram of another usage state of the utility model.

Detailed ways

As shown in Figure 1, an anti-reflux drainage tube that can be cleaned in use includes a tube body, and a one-way valve 1 is arranged in the tube body, and the one-way valve 1 divides the tube body into a front tube section on the side of the liquid inlet 2 and the rear pipe section 3 on the side of the liquid outlet. The liquid inlet leads to the operation area, and is used to absorb the liquid inside the operation area. The liquid outlet is connected with a negative pressure device 7, and the liquid in the operation area is sucked out from the drainage tube by the effect of negative pressure. As shown in Figure 2, due to the effect of the one-way valve 1, the liquid can only flow from the liquid inlet to the liquid outlet, but cannot flow back from the liquid outlet to the liquid inlet, thus avoiding the gradual weakening of the pressure due to the negative pressure device. , and the drainage tube is pulled and folded by external force, which may cause the drainage fluid to flow back into the operation area, thus creating the possibility of retrograde infection in the operation area.

The rear pipe section 3 is provided with a flushing device connected to the rear pipe section 3 . As shown in Figure 3, when the drainage tube needs to be cleaned, the disinfectant enters the rear pipe section 3 from the flushing device, and the one-way valve 1 prevents the disinfectant from entering the front pipe section 2 and thus enters the operation area, and only from the rear pipe section 3 The flow is directed to the outlet so that the irrigation function can also be used during use with the drain inserted in the surgical field.

As a further preferred embodiment, the one-way valve 1 includes 2 or 3 valves 1 that open toward the fluid outlet of the tubular body and are evenly divided. When there is effusion in the operation area, the valve 1 is opened to allow the effusion to pass through. If the negative pressure of the rear tube section 3 weakens or disappears, the valve 1 is closed and the fluid cannot flow back.

As a further preferred embodiment, the flushing device includes a flushing tube 4 communicating with the rear tube section 3 , and the flushing tube 4 is connected to the front end of the rear tube section 3 close to the one-way valve 1 . Entering the disinfectant from the rear tube section 3 close to the one-way valve 1 can make the rear tube section 3 obtain the most sufficient disinfection effect.

As a further preferred embodiment, the flushing tube 4 is provided with a flushing valve 5, and the drainage tube closes the flushing valve 5 during use, and opens the flushing valve 5 only when disinfection flushing is required.

As a further preferred embodiment, a piston conveyor 6 is installed at the end of the flushing pipe 4 . The sterilizing solution can be pushed into the rear pipe section 3 by the piston head of the piston conveyor 6 .

The above descriptions are only preferred implementations of the present utility model, and they do not constitute a limitation to the protection scope of the present utility model.
