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

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

The liquid-discharging bag (11) stores the discharged liquid discharged from the body.

A liquid pouring bag (11) is provided with a transparent window (13) for confirming the condition and color of a stored liquid. A transparent window (13) is provided along the vertical direction of the liquid-discharge bag (11).

A scale 15 is formed on one side of the transparent window 13 of the liquid-discharge bag 11. Thereby, the amount of the liquid to be drained stored in the liquid-discharging bag 11 can be easily grasped.

A gas discharge port 17 is provided in the upper area of the liquid-discharge bag 11 for smoothly discharging the gas and odor discharged from the liquid stored in the liquid-discharge bag 11 to the outside of the liquid-discharge bag 11.

A coupling ring 19 capable of rotating 360 degrees is provided on the upper end of the liquid-discharge bag 11, so that the liquid-pouch 11 can easily be hooked on a device or the like when the patient stays or moves on the bed.

A discharge tube (21) is attached to one side of the lower end of the liquid-discharge bag (11). Although not shown at the distal end of the discharge tube 21, a discharging clamp 23 for controlling the discharge of the liquid stored in the liquid-discharging bag 11 is mounted. Here, instead of the discharge clamp 23, a discharge valve (not shown) may be provided.

On the other hand, at the upper end of the liquid-dispensing bag 11, the distal end portion of the tube 31 is hermetically fitted and inserted.

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

The tube 31 is also provided with a port 37 through which saline solution can be injected and discharged during collection of drainage for examination or gastric washing. The tube 31 between the port 37 and the air pump 35 is provided with a tube clamp 39 for blocking the fluid flowing along the tube 31 when collecting the fluid through the port 37 .

A backflow prevention valve 51 for a bag is attached to the end of the tube 31 accommodated in the liquid-discharge bag 11.

The bag backflow prevention valve 51 is constituted by a pair of membranes 53a and 53b and the pair of membranes 53a and 53b are arranged at the opposite side edges so as to form a drainage passage 55 through which the drainage flows in the center, Are adhered to each other, and are in close contact with and spaced from each other. That is, when the drainage does not flow to the central drainage passageway 55, the pair of membranes 53a and 53b adhere to each other, so that the outside drainage can not flow into the passage 55 of the drainage product. When the drainage material flows into the drainage passageway 55, the pair of membranes 53a and 53b are separated from each other, and the drainage material is smoothly discharged. Here, it is preferable that the drain passage 55 is opened when a pressure greater than the suction pressure acting on the pumping housing 63 acts on the bag backflow prevention valve 51.

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

The drain pump pumping section 61 has a pumping housing 63, an inlet port 65, an outlet port 67, and a pumping check valve 71 for pumping.

The pumping housing 63 has a hollow cylindrical shape for accommodating a predetermined volume of liquid and has a relatively larger diameter than the tube 31. The pumping housing 63 is mounted to the tube 31 so that the tube 31 can be elongated and reduced in length along the length of the tube 31. The pumping housing 63 preferably has a constant elasticity and is made of a material having excellent elasticity. Although not shown in the drawings, a wrinkle having a continuous wavy shape along the longitudinal direction of the tube 31 may be formed on the outer surface of the pumping housing 63 to multiply the expansion and contraction of the pumping housing 63.

At one side of the pumping housing 63 is formed an inlet port 65 through which the waste material flows into the pumping housing 63 and the inlet port 65 communicates with the flow path 33 of the tube 31.

The discharge port 67 is formed at the other side of the pumping housing 63 so that the drainage contained in the pumping housing 63 is discharged toward the drainage bag 11. The discharge port 67 is connected to the flow path 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 to the tube 31 through the inlet 65, and the expansion and contraction of the pumping housing 63 Backward valve 71 for opening and closing the inlet 65 by means of the backflow prevention valve 71 for pumping.

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.

Thereby, the drain pump pumping section 61 sucks the drainage in the body to the expansion and contraction action of the pumping housing 63 to the pumping housing 63, or the drainage solution housed in the pumping housing 63 flows toward the drainage bag 11 .

The drain pumping section 61 further includes an elastic member 81 accommodated in the pumping housing 63 and providing an elastic force such that the inlet 65 and the outlet 67 are spaced apart from each other.

As described above, the resupply pumping section 61 is further provided with the elastic member 81, so that the receiving volume of the pumping housing 63 is kept constant, and the pumping housing 63 And at the same time a suction pressure is generated so as to suck the drip material in the body into the pumping housing 63 so that the drip material in the body can be swiftly and smoothly discharged.

Although the elastic member 81 is illustrated as being accommodated in the pumping housing 63 in the present embodiment, the elastic member 81 is not limited thereto. The elastic member 81 may be provided outside the pumping housing 63. In this embodiment, the coil spring is shown as the elastic member 81, but the present invention is not limited to this, and various types of elastic members 81 such as leaf springs and sponges may be provided as the elastic members 81.

Reference numeral 41 is a connector for connecting the tube 31 to a drain tube connected to the body.

With this configuration, a process of draining a liquid in the body using the liquid-dispensing bag assembly 10 according to an embodiment of the present invention will be described.

Prior to the explanation, it is clarified beforehand that the moving state of the drainage is shown by arrows in Figs. 1 to 4.

When the pumping housing 63 is compressed so that the length of the pumping housing 63 is reduced after interconnecting the drainage tube and the liquid pouch 11 connected to the body by the tube 31, the pumping housing 63 has its own elasticity and elasticity And the suction pressure is generated in the pumping housing 63. The suction force is generated by the elastic force of the member 81,

1, the pumping backflow prevention valve 71 is pivoted to the inside of the pumping housing 63 to open the inlet port 65 and the liquid in the body flows along the tube 31 And flows into the pumping housing 63 through the inlet 65. [ At this time, as the backflow prevention valve for bag 51 is subjected to a pressure smaller than the pressure for opening the drainage passage 55, The bag backflow prevention valve 51 is kept closed as shown in Fig.

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

As the pumping housing 63 is compressed, a pressing force is applied toward the inlet port 65 and the outlet port 67 of the pumping housing 63 in the pumping housing 63, The inlet port 65 is closed by being brought into close contact with the inlet port 65 of the pumping housing 63 and at the same time the pair of membranes 53a and 53b of the bag backflow prevention valve 51 are spaced apart Thereby opening the drainage passage 55 as shown in Fig.

The drain water contained in the pumping housing 63 does not flow back into the tube 31 through the inlet 65 of the pumping housing 63 but flows through the discharge port 67 of the pumping housing 63, And is smoothly discharged and stored in the liquid-discharging bag 11 through the liquid-discharging opening 51.

Accordingly, when the pumping housing 63 is compressed in accordance with the expansion and contraction of the pumping housing 63, the drip contained in the pumping housing 63 is guided to the tube 31 through the inlet 65 of the pumping housing 63 And is stored in the drainage bag 11 through the backflow prevention valve 51 for the bag via the outlet 67 of the pumping housing 63 without returning.

When the compressed pumping housing 63 is elongated by the elastic force, the backflow prevention valve 71 for pumping is opened by the suction pressure generated in the pumping housing 63, , The bag backflow prevention valve 51 is kept closed.

It is possible to quickly discharge the drainage fluid by a simple operation, to prevent backflow of the drainage fluid, to improve the convenience of use, and to shorten the working hours of the medical staff.

In the above-described embodiments, the liquid-dispensing bag assembly is limited to a liquid-dispensing bag, a tube, and a liquid-pumping unit.
