As shown in fig. 1 to fig. 2, an embodiment of the present invention provides a drainage device, including:

the drainage bag 1 is provided with a port 11 for the inflow of drainage liquid;

the drainage tube 2 is communicated with the interface 11, the drainage tube 2 is provided with a three-way valve 3, and the three-way valve comprises a first opening 31, a second opening 32 and a third opening 33 which can be communicated in pairs;

the first opening 31 is connected with a section of the drainage tube 2 far away from the drainage bag 1;

the second opening 32 is connected with a section of the drainage tube 2 close to the drainage bag 1;

the third opening 33 is used for drawing a drainage fluid sample or injecting a drug.

The application provides a drainage device sets up three-way valve 3 on drainage tube 2, through adjusting in first opening 31, second opening 32, the third opening 33 which two communicate each other, can satisfy drainage, sampling, wash, pour into the medicine and remain a plurality of demands such as, and need not to dismantle drainage bag 1 and drainage tube 2, can the simplified operation, raise the efficiency to can reduce the contaminated probability of drainage bag.

Specifically, the drainage tube 2 is divided into a first section between the three-way valve 3 and the patient and a second section between the three-way valve 3 and the drainage bag 1 due to the three-way valve 3; the first opening 31 of the three-way valve 3 is connected with a section of the drainage tube 2 far away from the drainage bag 1, namely, one end of the section of the drainage tube 2 extends into a wound of a patient, and the other end of the section of the drainage tube is connected with the first opening 31 of the three-way valve; the second opening 32 is connected with a section of the drainage tube 2 close to the drainage bag 1, which means that one end of the section of the drainage tube is connected with the second opening 32 of the three-way valve, and the other end is connected with the connector 11 of the drainage bag.

Since the three-way valve 3 can make two of the first opening 31, the second opening 32 and the third opening 33 communicate with each other and the other opening is closed, the following operations can be implemented according to different requirements:

during normal drainage, the first opening 31 and the second opening 32 are communicated, the third opening 33 is closed, and drainage liquid flows into the drainage bag 1 from the wound of the patient through the drainage tube 2.

When a drainage liquid sample needs to be collected for inspection, the first opening 31 and the third opening 33 are communicated, so that the second opening 32 is closed, and the drainage liquid flowing out of the wound of the patient flows out through the third opening 33 to be collected for inspection. The collection procedure may be performed using a syringe inserted into the third opening 33.

When the medicine needs to be injected, the first opening 31 and the third opening 33 are firstly communicated, so that the second opening 32 is closed, the medicine is injected from the third opening 33, so that the medicine enters a section of the drainage tube 2 communicated with the patient, and then the first opening 31 is closed, so that the medicine can be retained in the section of the drainage tube 2 communicated with the patient without additionally using a clamp; after the preset retention time is reached, the first opening 31 and the second opening 32 are communicated, and the mixed liquid of the medicine and the drainage liquid flows into the drainage bag and can continuously perform drainage.

Preferably, at least part of the wall of the drainage tube 2 is provided with corrugations to form a telescopic part 21.

Further, a plurality of telescopic parts 21, for example, 2-3 telescopic parts 21, may be provided at the drainage tube 2. The plurality of telescopic parts 21 are provided at different positions of the drainage tube 2 as needed.

Since the drainage bag 1 has a large volume and a heavy weight after being filled with drainage fluid, it is usually necessary to adjust the position between the drainage bag 1 and the patient, and therefore, it is preferable that the bellows 21 be provided between the three-way valve 3 and the port 11. When a plurality of the telescopic parts 21 are provided, the telescopic parts 21 may be provided at the drains 2 on both sides of the three-way valve 3, respectively.

Preferably, the drainage bag 1 is further provided with an outlet 12 for drainage liquid to be discharged, the outlet 12 is provided with a first drainage valve 4, the outlet 12 is further connected with a metering device 5, a shell of the metering device 5 is a hard shell, and the metering device 5 is provided with scales.

Clinically, the water inlet and outlet amount of some patients needs to be calculated, and drainage liquid is an important component of the output amount and needs to be strictly observed and accurately measured; for the convenience of use by patients, the drainage bag 1 is soft and irregular in shape, the measurement is not accurate enough by observing the measurement scale lines on the surface of the drainage bag body, the observation and judgment of the state of an illness are influenced, and the operation is not convenient enough if the drainage bag is poured into other measuring instruments for measurement. Consequently, the device of leading way that this application provided still prefers to set up metering device 5 in drainage bag 1 below, and 5 casings of metering device are the stereoplasm casing, metering device 5 non-deformable itself, just metering device 5 is equipped with the scale, can be accurate, convenient reading degree in leading into metering device 5 with the drainage liquid to confirm the volume of drainage liquid.

Preferably, the metering device 5 is further provided with a drain port 51 for draining drainage fluid, and the drain port 51 is provided with a second drain valve 6.

The metering device 5 can be arranged smaller than the drainage bag 1, so that the metering device 5 can be carried along with the drainage bag 1 without influencing the movement of the patient. For example, the metering device 5 is set to have a capacity of 100ml and the graduation marks are 5 ml/grid.

When the drainage bag is used, the drainage liquid with larger volume in the drainage bag 1 is put into the metering device 5 in batches for metering by controlling the first drainage valve 4 arranged at the outlet 12 of the drainage bag 1, and then the sum is calculated; the measured drainage liquid is discharged and discarded or treated by other processes under the control of a second drainage valve 6 at a drainage port 51.

In addition, the metering device 5 and the drainage bag 1 can be detachably connected, and the metering device 5 can be connected to the drainage bag 1 for use when needed.

Preferably, the metering device 5 has a rectangular parallelepiped shape.
