Description

Technical Field

[0001] This utility model belongs to the field of medical drainage bag technology, specifically relating to an adjustable disposable drainage bag. Background Technology

[0002] Disposable drainage bags are clinically used for postoperative drainage of urine or organs in the chest, abdomen, and pelvis. When draining fluid, especially pleural effusion and ascites, it is important to avoid draining too much or too quickly at once. In some patients with severe conditions, this can easily cause discomfort and pose certain risks. Existing drainage bags do not allow for adjustment of the bag's internal volume, making it difficult to control the amount of fluid drained. Therefore, we propose an adjustable disposable drainage bag. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable disposable drainage bag to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solution: an adjustable disposable drainage bag, comprising a bag body and an inlet pipe and an outlet pipe disposed on the bag body, wherein the inner cavity of the bag body is composed of multiple independent liquid storage chambers, and a connecting component is provided between the liquid storage chambers, the connecting component being configured to adjust the volume of the inner cavity of the bag body, the inner diameter of the connecting component being adjustable to adjust the drainage speed of the drainage bag.

[0005] As a further embodiment of this utility model, the connecting component includes a locking strip and a locking groove, which can be engaged and sealed together. The locking strip and the locking groove are respectively adhered and fixed to the two side walls of the bag body, and the locking strip and the locking groove are located between two adjacent independent liquid storage chambers.

[0006] As a further embodiment of this utility model, a connecting pipe is provided between the two adjacent independent liquid storage chambers. The connecting pipe is connected to the first liquid storage chamber and the second liquid storage chamber respectively. A regulating valve is provided on the connecting pipe, and the connecting pipe passes through the regulating valve. A clamping bolt is provided on the regulating valve along the radial direction of the connecting pipe.

[0007] As a further embodiment of this utility model, any of the independent liquid storage chambers is provided with volume scale lines.

[0008] The beneficial effects of this utility model are as follows: By dividing the bag into multiple independent liquid storage chambers, the volume of liquid drainage can be controlled. When the independent liquid storage chamber near the inflow pipe end is full, the connecting component is further opened to connect the second liquid storage chamber with the first liquid storage chamber, thereby expanding the volume of the bag. At the same time, the connecting component is equipped with an adjustment device to adjust the flow rate of liquid between the first and second liquid storage chambers, thereby adjusting the drainage speed. The operation is convenient and quick. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 In this embodiment of the present invention, an adjustable disposable drainage bag includes a bag body and an inflow pipe 3 and an outflow pipe 6 disposed on the bag body. The bag body is characterized in that the inner cavity of the bag body is composed of multiple independent liquid storage chambers, and a connecting component is provided between the liquid storage chambers. The connecting component is configured to adjust the volume of the inner cavity of the bag body, and the inner diameter of the connecting component is adjustable to adjust the drainage speed of the drainage bag.

[0017] Before use, the air inside the bag is removed. During use, the inflow tube 3 on the bag is connected to the patient's body. Due to the low pressure inside the bag, the accumulated fluid in the patient's body is drawn into the bag through the inflow tube 3, dividing the bag's inner cavity into several independent storage chambers. The volume of each independent storage chamber is relatively constant. When one independent storage chamber is full, the patient can choose whether to connect adjacent storage chambers to the full chamber, depending on the amount of fluid in the patient's body. Since the patient initially has a large amount of fluid, the amount decreases after collecting a certain amount. If the bag's volume is too large, it can easily lead to fluid imbalance and discomfort. Therefore, by dividing the bag into multiple independent storage chambers, the drainage capacity can be controlled. When the independent storage chamber near the end of the inflow tube 3 is full, the connecting component is opened to connect the second storage chamber with the first, thereby increasing the bag's volume. At the same time, the connecting component is equipped with an adjustment device to adjust the flow rate of fluid between the first and second storage chambers, thus adjusting the drainage speed. The operation is convenient and quick.

[0018] In some embodiments, such as Figure 3 and 4 As shown, the connecting component includes a retaining strip 7 and a retaining groove 8. The retaining strip 7 and the retaining groove 8 can be engaged and sealed. The retaining strip 7 and the retaining groove 8 are respectively glued and fixed to the two side walls of the bag body. The retaining strip 7 and the retaining groove 8 are located between the adjacent first liquid storage chamber 1 and second liquid storage chamber 2. That is, the bag body is divided into multiple liquid storage chambers by the cooperation of the existing sealing soft rubber retaining strip and the retaining groove. The retaining strip 7 and the retaining groove 8 can be separated externally. At the same time, the distance between the retaining strip 7 and the retaining groove 8 can be adjusted, thereby realizing the speed of liquid flow between the first liquid storage chamber 1 and the second liquid storage chamber 2.

[0019] In another embodiment, such as Figure 2 As shown, a connecting pipe 4 is provided between two adjacent independent liquid storage chambers. The connecting pipe 4 is connected to the first liquid storage chamber 1 and the second liquid storage chamber 2 respectively. A regulating valve 5 is provided on the connecting pipe 4. The connecting pipe 4 passes through the regulating valve 5. A clamping bolt is provided on the regulating valve 5 along the radial direction of the connecting pipe 4. The closing of the connecting pipe 4 and the flow rate of the liquid accumulation between the first liquid storage chamber 1 and the second liquid storage chamber 2 can be controlled by turning the regulating valve 5. The operation is convenient and quick.

[0020] More preferably, each of the independent fluid storage chambers is provided with a volume scale line, which facilitates medical staff to visually observe the drainage volume of the patient's accumulated fluid.
