[0035] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0038] The existing drainage bag can cause the problems of clogging or poor drainage when the patient gets out of bed or sits in a posture that causes the drainage bag to be bent or squeezed. Moreover, the above-mentioned drainage bag relies on gravity drainage and cannot be used with a negative pressure device, thereby existing the problem of easy backflow. If used with a negative pressure device, the drainage hose needs to be communicated with the negative pressure device. Because the permeate in the drainage bag has strong fluidity, it can flow into the negative pressure device along the drainage hose, causing damage or clogging of the negative pressure device.

[0039] Referring to Figure 1 and Figure 2The utility model discloses a disposable portable drainage bag, which comprises a bag body 100, a liquid absorbing interlayer 200, a filter 300, a negative pressure pipe 400 and a drainage pipe 500.

[0040] Specifically, in the embodiment, referring to Figure 1 The bag body 100 has two partition portions 120, and the bag body 100 is divided into three chambers 110 arranged along the length direction of the bag body 100. Further, the negative pressure pipe 400 and the drainage pipe 500 are integrally formed with the bag body 100. Of course, the negative pressure pipe 400 and the drainage pipe 500 can be bonded with the bag body 100, which should also be within the protection scope of the utility model embodiment.

[0041] When the disposable portable drainage bag is used, the drainage pipe 500 is used to communicate with the patient, the negative pressure pipe 400 is used to communicate with the negative pressure equipment, and the negative pressure equipment provides negative pressure to make the liquid flow into the bag body 100 from the drainage pipe 500. The liquid is adsorbed by the liquid absorbing interlayer 200 after entering the bag body 100, and the drainage pipe 500 and the negative pressure pipe 400 are removed when the liquid absorbing interlayer 200 is full or other conditions requiring the drainage bag to be removed.

[0042] The filter 300 is installed between the bag body 100 and the negative pressure pipe 400, and the filter 300 is air-permeable and water-impermeable, which effectively ensures that the exudate will not enter the negative pressure equipment along the negative pressure pipe 400 when the bag body 100 is full of liquid.

[0043] The partition portion 120 divides the bag body 100 into a plurality of chambers 110 in communication with each other; when the bag body 100 has one partition portion 120, the bag body 100 is divided into two chambers 110 in communication with each other; when the bag body 100 has a plurality of partition portions 120, the plurality of partition portions 120 are arranged at intervals along the length direction of the bag body 100, and the bag body 100 is divided into more than two chambers 110 in communication with each other. In the drainage process, the exudate will fill each chamber 110 in turn from bottom to top, ensuring full application of the drainage bag space; even if bending occurs, the exudate can still enter the secondary chamber 110 through the osmotic effect when passing through the communication passage between the two adjacent chambers 110.

[0044] The chamber 110 is filled with a liquid absorption interlayer 200, which absorbs the liquid in the bag body 100 by its adsorption, effectively avoiding the backflow of the liquid in the bag body 100, and the liquid can permeate through the liquid absorption interlayer 200, and the patency of the drainage bag can be ensured regardless of the extrusion state of the bag body 100.

[0047] Specifically, the water-absorbing resin (Super Absorbent Polymer, SAP for short) is a new type of functional high polymer material; it has the function of absorbing several hundred to several thousand times water than itself, and has excellent water retention performance, and once it absorbs water and expands into a hydrogel, it is difficult to separate the water even under pressure. The high water-absorbing resin is a functional high polymer material with a large number of hydrophilic groups. The water-absorbing resin is a gel-like substance after absorbing water, effectively avoiding the backflow of the liquid in the bag body 100, and being more convenient than the traditional tube clamp form.
