Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid storage bags, in particular to a waste liquid storage bag which is convenient for dumping waste liquid. Background Art

[0002] Currently, when collecting waste liquid in clinical practice, the corresponding CRRT waste liquid collection bag is needed. When conducting CRRT treatment, the patient's waste liquid needs to be processed. When the treatment is completed, the waste liquid also needs to be processed immediately.

[0003] A CRRT waste liquid storage bag generally has a liquid inlet and a liquid outlet, through which the waste liquid is discharged. In order to facilitate the discharge of waste liquid, the waste liquid bag in the prior art is provided with a longer discharge pipe on the liquid outlet of the waste liquid bag, which is used to shorten the distance between the waste liquid bag and the collection device, thereby avoiding the problem of splashing or leakage of waste liquid during discharge due to the height difference between the two.

[0004] However, because the outlet is lengthened, after the outlet valve is closed, there will still be residual liquid in the discharge pipe. If the collection device is removed at this time, the waste liquid inside the discharge pipe will drip onto the ground or other waste collection devices, causing environmental pollution and even cross infection. Therefore, in view of the above problems, a waste liquid storage bag that is convenient for waste liquid dumping is now proposed to solve the above defects. Utility Model Content

[0005] The utility model aims to provide a waste liquid storage bag for convenient dumping of waste liquid, so as to solve the problem in the above background technology that after the liquid outlet is extended, waste liquid is retained in the discharge pipe and the waste liquid will drip.

[0008] As a further solution of the utility model: wherein, the extension tube is fixedly installed with an elastic hook on the end face away from the discharge pipe, and a fixing seat is fixedly installed at the connection between the discharge pipe and the extension tube, and a hanging plate corresponding to the position and size of the elastic hook is fixedly installed on the fixing seat.

[0009] As a further solution of the utility model: wherein, a covering portion is provided at the end point of the elastic hook, a docking portion is provided on the hanging plate, the covering portion corresponds to the docking portion, and the covering portion can be inserted into the docking portion.

[0010] As a further solution of the utility model: wherein, the hanging plate is provided with a placement groove corresponding to the extension tube body.

[0011] As a further solution of the utility model: wherein, the extension tube is made of elastic material.

[0012] As a further solution of the utility model: wherein, a throttle valve is arranged on the liquid inlet, and the throttle valve can be used to control the flow of liquid into the bag body, and a hanging hole is arranged above the bag body.

[0013] As a further solution of the utility model: wherein, a control valve is provided on the drain pipe, and the control valve is screwed inward to squeeze the drain pipe, and the drain pipe outlet is closed, and the liquid cannot flow out; when the control valve is screwed outward, the drain pipe outlet is opened, and waste liquid can flow out of the drain pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The waste liquid storage bag, which is convenient for dumping waste liquid, has the cover portion corresponding to the docking portion, and the cover portion can be inserted into the docking portion to form a stable docking. When the extension tube is not in use, the end of the extension end can be hung on the hanging plate through the cover portion and the docking portion to prevent the waste liquid retained in the extension tube from continuing to drip.

[0024] See also Figure 1 A waste liquid storage bag for convenient dumping of waste liquid comprises a bag body 10 for storing waste liquid, wherein the bag body 10 is provided with a liquid inlet 11 on the top and a liquid outlet 12 on the bottom, and a throttle valve 13 is provided on the liquid inlet 11, through which the throttle valve 13 can control the flow of liquid into the bag body 10.

[0025] Furthermore, the liquid outlet 12 is arranged at the midline of the bag body 10, and the bottom of the bag body 10 is designed in an arc shape. In this embodiment, the bottom of the bag body 10 is designed in an arc shape, so that the liquid outlet 12 is at the lowest point of the liquid flow, thereby facilitating the complete discharge of the waste liquid. In order to facilitate the storage / hanging of the bag body 10, a hanging hole 14 is arranged above the bag body 10, and a hook can also be arranged to complete the hanging of the bag body 10.

[0026] On the basis of the prior art, the waste liquid storage bag also includes a discharge mechanism 20 arranged at the liquid outlet 12, and the discharge mechanism 20 includes a discharge pipe 21 designed to be connected to the liquid outlet 12 arranged on the bag body 10, and a control valve 22 is arranged on the discharge pipe 21. The control valve 22 is screwed inward to squeeze the discharge pipe 21, and the outlet of the discharge pipe 21 is closed, and the liquid cannot flow out at this time; when the control valve 22 is screwed outward, the outlet of the discharge pipe 21 is opened, and the waste liquid can flow out from the discharge pipe 21.

[0027] Of course, in order to better allow the waste liquid to enter the collection device, such as Figures 2 to 6As shown, an extension mechanism 30 is provided below the drain pipe 21, and the extension mechanism 30 includes an extension pipe 31 designed to be connected to the drain pipe 21 at one end, and an elastic hook 32 is fixedly installed on the end face of the extension pipe 31 away from the drain pipe 21, and a fixing seat 33 is fixedly installed at the connection between the drain pipe 21 and the extension pipe 31, and a hanging plate 34 corresponding to the position and size of the elastic hook 32 is fixedly installed on the fixing seat 33. In this embodiment, when in use, the elastic hook 32 can be removed from the hanging plate 34, and at this time, the extension pipe 31 changes from the initial curved state to a straight line, thereby increasing the liquid outlet length, which facilitates the discharge of waste liquid from the bag body 10 into the collection device (waste liquid collection barrel).

[0028] Furthermore, a covering portion 321 is provided at the end point of the elastic hook 32, and a docking portion 341 is provided on the hanging plate 34. The covering portion 321 corresponds to the docking portion 341, and the covering portion 321 can be inserted into the docking portion 341 to form a stable docking. When the extension tube 31 is not in use, the end of the extension end 31 can be hung on the hanging plate 34 by the covering portion 321 and the docking portion 341 to prevent the waste liquid retained in the extension tube 31 from continuing to drip. On the one hand, it can avoid the problem that the waste liquid retained in the extension tube 31 continues to drip after the control valve 22 is closed after the extension tube 31 is extended, and at the same time, it can also avoid the inconvenience of the longer extension tube 31 during the use of the waste liquid bag.

[0029] However, because the height of the waste liquid storage bag is not consistent during use, the extension tube 31 may be too close to the collection device after being lowered, and the lower end of the extension tube 31 may be immersed in or contact with the waste liquid in the waste liquid collection device. In order to avoid this problem, the following improvements have been made.

[0030] First, a placement groove 342 corresponding to the tube body of the extension tube 31 is provided on the hanging plate 34. In this embodiment, the distance between the extension tube 31 and the collection device can be changed by placing the tube body of the extension tube 31 into the placement groove 342, and the extension tube 31 placed in the placement groove 342 will not affect the drainage problem. After use, the elastic hook 32 can be hung on the hanging plate 34.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
