Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description, hereinafter, the drainage is hereinafter referred to as a general term for exudates, gastrointestinal drainage, and the like, which accumulate in the body.

1 and 2 show a drain bag assembly according to an embodiment of the present invention.

As shown in these drawings, the drain bag assembly 10 according to an embodiment of the present invention includes a drain bag 11, a tube 31, and a drain pumping portion 61.

The drainage bag 11 stores drainage discharged from the body.

The drainage bag 11 is provided with a transparent window 13 to check the state and color of the stored drainage. The transparent window 13 is provided along the vertical direction of the drainage bag 11.

A scale 15 is formed on one side of the transparent window 13 of the drainage bag 11. Thereby, it is possible to easily grasp the amount of drainage stored in the drainage bag 11.

In the upper region of the drain bag 11, a gas outlet 17 for smoothly discharging gas and odor discharged from the drainage stored in the drain bag 11 to the outside of the drain bag 11 is provided.

The upper end of the drainage bag 11 is provided with a hook 19 for rotation that can be rotated 360 degrees, so that the drainage bag 11 can be easily hanged on equipment or the like when the patient stays on the bed or moves.

A discharge tube 21 is mounted on one side of the lower end of the drainage bag 11. Although not shown at the distal end of the discharge tube 21, a discharge clamp 23 for controlling discharge of the drainage stored in the drainage bag 11 is mounted. Here, a discharge valve (not shown) may be provided in place of the discharge clamp 23.

On the other hand, the distal end of the tube 31 is maintained at the upper end of the drainage bag 11, and is inserted into it.

The tube 31 is made of a cannula tube, and interconnects a drain tube (not shown) connected to the body and a drain bag 11. The tube 31 forms a flow path 33 through which drainage discharged from the body flows. The tube 31 is preferably made of a flexible material that can freely deform the path shape between the drain tube and the drain bag (11).

The tube 31 is provided with an air pump 35 for promoting drainage when drainage of drainage is not smooth.

In addition, the tube 31 is branched with a port 37 capable of injecting and discharging physiological saline at the time of collecting or draining for drainage for inspection. In the tube 31 between the port 37 and the air pump 35, a clamp 39 for a tube that blocks the drainage flowing along the tube 31 when collecting the drainage through the port 37 Can be prepared.

A backflow prevention valve 51 for a bag is mounted at the end of the tube 31 accommodated in the drainage bag 11.

The backflow prevention valve 51 for the bag is made of a pair of membranes 53a and 53b, and the pair of membranes 53a and 53b have both edges so as to form a drainage passage 55 through which the drainage flows in the center. Are mutually adhered, and mutually close and spaced. That is, when the effluent does not flow through the central effluent passage 55, the pair of membranes 53a and 53b adhere to each other so that the external effluent cannot flow into the effluent passage 55. When the effluent flows into the effluent passage 55, the pair of membranes 53a, 53b are spaced apart from each other, and the effluent is smoothly discharged. Here, when the pressure greater than the suction pressure acting on the pumping housing 63 is applied to the bag backflow prevention valve 51, it is preferable that the drainage passage 55 is opened.

On the other hand, a drainage pumping portion 61 is provided on the tube 31 facing the drainage bag 11.

The drainage pumping part 61 has a pumping housing 63, an inlet 65, an outlet 67, and a backflow prevention valve 71 for pumping.

The pumping housing 63 has a hollow cylindrical shape accommodating a certain volume of drainage, and has a relatively larger diameter than the tube 31. The pumping housing 63 is mounted to the tube 31 so as to be elongated and contracted in length along the longitudinal direction of the tube 31. The pumping housing 63 is preferably made of a material having a certain elastic force and excellent elasticity. In addition, although not shown, by forming a wrinkle having a continuous wave shape along the longitudinal direction of the tube 31 on the outer surface of the pumping housing 63, it is also possible to double the elastic force of the pumping housing (63).

On one side of the pumping housing 63, an inlet 65 through which drainage flows into the pumping housing 63 is formed, and the inlet 65 communicates with the flow path 33 of the tube 31.

On the other side of the pumping housing 63, an outlet 67 through which drainage contained in the pumping housing 63 is discharged toward the drainage bag 11 is formed, and the outlet 67 is a flow path of the tube 31 ( 33).

On the other hand, in the region of the inlet 65 of the pumping housing 63, the drainage contained in the pumping housing 63 is prevented from flowing back into the tube 31 through the inlet 65, and the expansion and contraction action of the pumping housing 63 By the inlet 65 is provided with a pump backflow prevention valve 71 for opening and closing.

The backflow prevention valve 71 for pumping has a plate shape and is rotatably coupled to the inlet 65 of the pumping housing 63 to open and close the inlet 65.

Thus, the drainage pumping unit 61 sucks the drainage from the body into the pumping housing 63 due to the stretching action of the pumping housing 63 or the drainage received in the pumping housing 63 toward the drainage bag 11 Discharge.

In addition, the drainage pumping unit 61 is accommodated in the pumping housing 63, the inlet 65 and the outlet 67 further includes an elastic member 81 that provides elastic force to maintain a predetermined distance.

As described above, by further providing the elastic member 81 in the drainage pumping portion 61, the receiving volume of the drainage of the pumping housing 63 is kept constant, and the pumping housing 63 when the pumping housing 63 is elongated ), And at the same time, a suction pressure is generated to suck the effluent in the body into the pumping housing 63, so that the effluent in the body can be drained quickly and smoothly.

Here, in this embodiment, the elastic member 81 is shown as being accommodated in the pumping housing 63, but is not limited thereto, and the elastic member 81 may be provided outside the pumping housing 63. In addition, in this embodiment, although the coil spring is shown as the elastic member 81, the present invention is not limited thereto, and as the elastic member 81, various types of elastic members 81, such as a plate spring and a sponge, may be provided.

In addition, reference numeral 41, which is not described, is a connector for connecting the tube 31 to the drainage pipe connected to the body.

With this configuration, a description will be given of the process of draining the drainage material in the body using the drainage bag assembly 10 according to an embodiment of the present invention.

Prior to the description, it is revealed in FIG. 1 to FIG. 4 that the movement state of the effluent was illustrated with an arrow.

After the drain tube connected to the body and the drain bag 11 are interconnected with the tube 31, when the pumping housing 63 is compressed so that the pumping housing 63 is reduced in length, the pumping housing 63 has its own elastic force and elasticity. The length is extended by the elastic force of the member 81, and suction pressure is generated in the pumping housing 63.

Accordingly, as shown in FIG. 1, the backflow prevention valve 71 for pumping rotates inside the pumping housing 63 to open the inlet 65 and at the same time, the drainage in the body follows the tube 31. It flows and flows into the pumping housing 63 through the inlet 65. At this time, as the pressure applied to the backflow prevention valve 51 for the bag is smaller than the pressure for opening the drainage passage 55. As shown in Figure 2, the bag backflow prevention valve 51 maintains a closed state.

Subsequently, when a certain volume of drainage is received in the elongated pumping housing 63, the pumping housing 63 is compressed so that the pumping housing 63 is reduced in length.

As the pumping housing 63 is compressed, a pressing force is applied toward the inlet 65 and the outlet 67 of the pumping housing 63 in the pumping housing 63, and the backflow prevention valve 71 for pumping is shown in FIG. 3 As shown in the close contact with the inlet 65 of the pumping housing 63 to close the inlet 65, and at the same time a pair of membranes (53a, 53b) of the bag backflow prevention valve 51 is spaced apart from each other 4, the drainage passage 55 is opened.

Thus, the drainage contained in the pumping housing 63 does not flow back into the tube 31 through the inlet 65 of the pumping housing 63, but through the outlet 67 of the pumping housing 63, the backflow prevention valve for the bag It is smoothly discharged and stored in the drainage bag 11 through 51.

Therefore, according to the expansion and contraction action of the pumping housing 63, that is, when the pumping housing 63 is compressed, the drainage contained in the pumping housing 63 passes through the inlet 65 of the pumping housing 63 to the tube 31. It does not flow back and is stored in the drain bag 11 through the backflow prevention valve 51 for the bag through the outlet 67 of the pumping housing 63.

When the compressed pumping housing 63 is extended by an elastic force, the backflow prevention valve 71 for pumping is opened by the suction pressure generated in the pumping housing 63, and the body fluid is introduced into the pumping housing 63. , The backflow prevention valve 51 for a bag is kept in a closed state.

With a simple operation, the drainage can be quickly discharged, and the backflow of the drainage can be prevented, the convenience of use can be improved, and the working hours of the medical staff can be shortened.

In the above-described embodiment, the drain bag assembly is described as being limited to a drain bag, a tube, and a drain pumping unit. However, the drain bag assembly according to the present invention may be formed of a tube and drain pumping unit.

The embodiments of the present invention have been described above with reference to the accompanying drawings, but a person skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing its technical spirit or essential features. You will understand. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive.
