Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a drainage bag that is easy to replace. Background Technology

[0002] For patients with ascites, a drainage tube will be placed after surgery. To facilitate the patient's movement and prevent infection, a drainage bag is usually installed in conjunction with the drainage tube to store the fluid, and it is changed in a timely manner.

[0003] For example, Chinese Patent No. CN209332826U discloses a fixed drainage bag for a disposable drainage tube, which discloses that a drainage bag is placed outside the drainage tube to store accumulated fluid, and the drainage bag is glued to the patient's abdomen to keep the drainage bag fixed.

[0004] As fluid accumulates in the drainage bag, it usually needs to be replaced. However, in the above-mentioned methods, when the drainage bag needs to be replaced, it is usually only possible to tear off a large area of ​​its adhesive part and forcefully tear it open, or to cut the drainage bag with a foreign object. This method is not only difficult for the operator to perform, but also can easily affect the drainage tube during the tearing of the adhesive part and the drainage bag, thus causing discomfort to the patient.

[0005] Therefore, providing a drainage bag that is easy to replace, so as to reduce the difficulty of replacement and avoid the impact on the drainage tube during the replacement process, is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a drainage bag that is easy to replace.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A replaceable drainage bag for connection to a drainage tube to store fluid discharged from the drainage tube, comprising:

[0009] The bag body has a liquid storage chamber;

[0010] The adhesive part is fixed to the bag body;

[0011] An installation hole penetrates the bag body and the adhesive part. The installation hole is used to connect with the drainage tube, and a flow channel connecting the liquid storage chamber is formed between a local area of ​​the installation hole and the outer wall surface of the drainage tube.

[0012] The first dividing groove extends from the mounting hole to the outer edge of the bag body;

[0013] The second dividing groove extends from the mounting hole to the outer edge of the adhesive part, and the second dividing groove extends in the same direction as the first dividing groove.

[0014] Preferably, it also includes an auxiliary tearing section;

[0015] The auxiliary tearing section includes a first partition and a second partition, which are arranged opposite to each other to form the first dividing groove;

[0016] The first partition and the second partition are fixedly connected to the opposite ends of the bag body, respectively.

[0017] Preferably, the first partition and / or the second partition protrude at least partially from the outer wall of the bag body to form a protrusion for the operator to apply force with their hand.

[0018] Preferably, it also includes auxiliary fasteners;

[0019] The auxiliary fastener is detachably located at the end of the bag body away from the adhesive part.

[0020] The auxiliary fastener extends from one side of the first partition to one side of the second partition to pull the first partition and the second partition into contact.

[0021] Preferably, the first and second partition grooves are arranged in multiple ways opposite to each other.

[0022] Preferably, the first dividing groove is provided as one;

[0023] The first dividing groove extends from the mounting hole to the end away from the liquid storage cavity.

[0030] The opening has an opening that connects to the outside and the liquid storage chamber, and the opening can be in an open state or a closed state.

[0031] Preferably, the opening is held in the closed state by itself being rolled up, and / or by a fixing clamp.

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0033] This utility model provides a replaceable drainage bag. Through the design of a first dividing groove extending from the mounting hole to the outer edge of the bag body, and a second dividing groove extending from the mounting hole to the outer edge of the adhesive part, when the drainage bag needs to be replaced, the operator only needs to apply force to the bag body from both ends of the first dividing groove to allow the two ends of the bag body and the two ends of the adhesive part to move along the groove. Figure 1 The bag is separated in directions S1 and S2, allowing the bag to be easily disconnected along the first dividing groove and the adhesive part to be separated along the second dividing groove. At this time, when the operator peels the adhesive part off the user's skin, neither the bag nor the adhesive part will pull on the drainage tube. At the same time, the drainage tube will not restrict the removal of the bag, which reduces the difficulty of replacing the drainage bag and avoids pulling on the drainage tube during the replacement of the drainage bag, thus improving the user experience.

[0043] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] See Figures 1 to 6 This utility model embodiment provides an easily replaceable drainage bag for connecting to the drainage tube 100 to store the liquid discharged from the drainage tube 100.

[0047] Specifically, the drainage bag includes a bag body 1, an adhesive part 2, a mounting hole 3, a first dividing groove 4, and a second dividing groove 5. The bag body 1 has a liquid storage chamber 11 for storing accumulated fluid; the adhesive part 2 is fixed to the bag body 1 for attaching the bag body 1 to the user's skin; the mounting hole 3 penetrates the bag body 1 and the adhesive part 2, and is used to connect to a drainage tube 100, with a local area of ​​the mounting hole 3 forming a flow channel connecting the liquid storage chamber 11 to the outer wall of the drainage tube 100; the first dividing groove 4 extends from the mounting hole 3 to the outer edge of the bag body 1; the second dividing groove 5 extends from the mounting hole 3 to the outer edge of the adhesive part 2, and the second dividing groove 5 extends in the same direction as the first dividing groove 4. This design allows the operator to apply force to the bag body 1 from both ends of the first dividing groove 4 when the drainage bag needs to be replaced, thereby causing the two ends of the bag body 1 and the two ends of the adhesive part 2 to move along the same direction. Figure 1 The bag body 1 is separated in the S1 and S2 directions, making it easy to disconnect the bag body 1 along the first dividing groove 4 and separate the adhesive part 2 along the second dividing groove 5. At this time, when the operator peels the adhesive part 2 off the user's skin, neither the bag body 1 nor the adhesive part 2 will pull on the drainage tube 100, and the drainage tube 100 will not restrict the removal of the bag body 1. This reduces the difficulty of replacing the drainage bag and avoids pulling on the drainage tube 100 during the replacement of the drainage bag, thus improving the user experience.

[0048] To further reduce the difficulty of replacing the drainage bag, the drainage bag also includes an auxiliary tear section 6, which can provide a force fulcrum for the operator.

[0049] Specifically, in this embodiment, the auxiliary tearing part 6 includes a first partition 61 and a second partition 62, which are arranged opposite to each other to form a first dividing groove 4. The first partition 61 and the second partition 62 are fixedly connected to the opposite ends of the bag body 1, so that the two ends of the bag body 1 opposite to the first dividing groove 4 are separated by the first partition 61 and the second partition 62, which can not only prevent leakage, but also make it easier for the operator to apply force.

[0050] Furthermore, the first partition 61 and the second partition 62 have greater resistance to deformation than the bag body 1.

[0051] To facilitate the operator's application of force when lifting the bag 1, the first partition 61 and / or the second partition 62 at least partially protrude from the outer wall surface of the bag 1, forming a protrusion 63 for the operator's hand to apply force. Specifically, in this embodiment, both the first partition 61 and the second partition 62 protrude from the bag 1 to form a protrusion 63, and the protrusion 63 protrudes from the end face of the bag 1. Of course, in other embodiments, the protrusion 63 may also protrude from the side wall surface of the bag 1, or one of the first partition 61 or the second partition 62 may protrude from the outer wall surface of the bag 1 to form a protrusion 63.

[0052] To improve the installation stability of the bag body 1, the drainage bag also includes auxiliary fixing parts 7.

[0053] In this embodiment, the auxiliary fastener 7 is detachably disposed at the end of the bag body 1 away from the adhesive part 2; the auxiliary fastener 7 extends from one side of the first partition 61 to one side of the second partition 62 to pull the first partition 61 and the second partition 62 to abut.

[0054] Furthermore, the auxiliary fastener 7 can be configured as an adhesive tape, a clip, or an elastic winding rope, etc., to achieve the contact between the first partition 61 and the second partition 62 by means of adhesion, clamping, or winding tension.

[0055] In this embodiment, a first dividing groove 4 is provided; the first dividing groove 4 extends from the mounting hole 3 to the end away from the liquid storage cavity 11, so that when the bag body 1 is disconnected from the first dividing groove 4, the liquid in the liquid storage cavity 11 will not leak. It is understood that a second dividing groove 5 is also provided, and extends from the mounting hole 3 to the end away from the liquid storage cavity 11.

[0056] Of course, in other embodiments, there may be multiple first partition slots 4 and second partition slots 5.

[0057] In this embodiment, the adhesive part 2 can fix the bag 1 to the surface of the user's skin, so as to achieve the fixed placement of the bag 1 and prevent the drainage tube 100 from being pulled by the accumulated liquid stored in the bag 1 when the user moves, thereby avoiding discomfort to the user to a certain extent.

[0058] Furthermore, the adhesive part 2 is provided with an annular structure surrounding the drainage tube 100. On the one hand, it can increase the bonding area between the adhesive part 2 and the user's skin; on the other hand, the annular adhesive part 2 can apply a certain supporting force to the drainage tube 100 radially, so as to prevent the drainage tube 100 from tilting or shifting, which is conducive to maintaining the stability of the drainage tube 100.

[0059] It is known that when the adhesive part 2 is attached to the edge of the mounting hole 3, the flow channel is formed on the inner edge of the adhesive part 2. In order to avoid liquid leakage to a certain extent, in this embodiment, the adhesive part 2 is set as a hydrophilic colloid.

[0060] In this embodiment, the bag body 1 includes an inner layer and an outer layer; the inner layer is a high-barrier membrane, and the outer layer is a water-repellent nonwoven fabric.

[0061] An opening 8 is provided at one end of the bag body 1 away from the first dividing groove 4; the opening 8 has an opening 80 that connects to the outside and the liquid storage chamber 11, and the opening 80 has an open state or a closed state.

[0062] Furthermore, the opening 80 remains closed by its own retraction, thereby avoiding an increase in the overall weight of the bag body 1. Of course, in other embodiments, the opening 8 is also held in place by a fixing clamp to keep the opening 80 closed, or the opening 80 can be kept closed by the retraction of the opening 8 itself and the sealing provided by the fixing clamp.

[0063] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
