[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a collection bag for exudate drainage, which has the following beneficial effects:

[0018] 1. This collection bag for seepage drainage is equipped with an installation mechanism, a filtration mechanism, and a fixing mechanism. The filter screen of the filtration mechanism is initially positioned by rectangular plates embedded in the mounting grooves of the support plate. The wedge plates of the fixing mechanism are slidably installed on both sides of the support plate. The wedge plates can be manually pushed inward by a U-shaped rod. The inclined surface of the wedge plate fits against the top of the rectangular plate. When the wedge plate slides inward, its inclined surface will press down on the rectangular plate, making the edge of the filter screen fit tightly against the inner wall of the rectangular groove, forming a seal. The fixing spring connects the wedge plate to the outside of the support plate and provides a reverse pulling force. When the U-shaped rod is manually released, the spring will pull the wedge plate outward, relieving the pressure on the rectangular plate and facilitating the removal and replacement of the filter screen. The seepage enters the collection bag through the through holes of the adhesive patch and the soft inner ring, first contacting the guide sleeve. The guide sleeve has a tapered structure that is wider at the top and narrower at the bottom, which guides the exudate to converge towards the center and reduces splashing. The exudate flows along the guide sleeve into the rectangular groove of the tray. At this time, the filter screen is placed horizontally in the rectangular groove to filter the exudate. The filter screen can effectively intercept impurities such as solid particles and tissue fragments in the exudate. The filtered exudate flows into the bottom of the collection bag through the drainage hole at the bottom of the tray and is finally discharged through the discharge pipe. The edge of the filter screen fits tightly against the inner wall of the rectangular groove to prevent the exudate from flowing directly into the collection bag around the filter screen, ensuring the filtration effect and achieving the purpose of having a filtration structure.

[0019] 2. This collection bag for seepage drainage has a support mechanism. The support mechanism's strips are fixed to the front and rear sides of the inner wall of the rectangular groove, symmetrically distributed from left to right. Each group of two strips jointly supports the central area of ​​the filter screen. The top of the strips is fixedly connected to the inner side of the guide sleeve and the inner side of the mounting ring plate through a support rod, forming a stable triangular support structure, which enhances the overall rigidity. The support rod ensures the normal use of the drainage channel and prevents the inner wall of the guide sleeve from sticking, thus achieving the purpose of having a support structure.

[0039] The discharge pipe 41 extends to the bottom of the collection bag to discharge the seepage in the collection bag. A valve 42 is movably installed on the pipe wall to facilitate the control of seepage discharge. The valve 42 controls the opening and closing of the discharge pipe 41 to prevent accidental discharge of seepage. It is easy to operate and has good sealing performance.

[0040] The mounting mechanism 5 includes a mounting ring plate 51. The mounting ring plate 51 is fixedly installed on the inner side of the connecting ring 33. A guide sleeve 52 is fixedly installed on the front side of the mounting ring plate 51. A support plate 53 is fixedly installed on the bottom of the guide sleeve 52. A rectangular groove 54 is opened on the top of the support plate 53. A drain hole 55 is opened on the bottom of the support plate 53 and communicates with the inner bottom wall of the rectangular groove 54. Two mounting grooves 56 are opened on the top of the support plate 53 and communicate with the left and right sides of the inner wall of the rectangular groove 54 respectively.

[0041] The mounting plate 51 is fixed inside the connecting ring 33, providing a mounting base for components such as the guide sleeve 52 and the support plate 53. The guide sleeve 52 provides a channel for the seepage to flow into the filter mechanism 6, and also plays a guiding and buffering role. It has a tapered structure that is wider at the top and narrower at the bottom, which facilitates the smooth flow of seepage into the filter screen 61. The support plate 53 supports the filter screen 61, ensuring its stability and filtration effect. A rectangular groove 54 and a mounting groove 56 are provided at the top to facilitate the installation and fixing of the filter screen 61. A drain hole 55 is provided at the bottom to facilitate the outflow of filtered seepage.

[0042] The filter mechanism 6 includes a filter screen 61. The filter screen 61 is movably installed inside the rectangular groove 54. Rectangular plates 62 are fixedly installed at both ends of the filter screen 61, respectively located inside the two mounting grooves 56.

[0043] The guide sleeve 52 has a tapered structure that is wider at the top and narrower at the bottom. The filter screen 61 is made of medical non-woven fabric or nylon. The pore size of the filter screen 61 is 0.1-0.5mm. The edge of the filter screen 61 fits against the inner wall of the rectangular groove 54.

[0044] The filter screen 61 filters impurities and solid particles in the exudate to prevent clogging of the discharge pipe 41 and affecting the observation of the exudate. It is a medical non-woven fabric or nylon filter screen with a pore size of 0.1-0.5mm, which has good filtration effect and biocompatibility. The edge fits into the inner wall of the rectangular groove 54 to ensure no leakage. The rectangular plate 62 fixes the two ends of the filter screen 61, which facilitates its installation and fixation in the installation groove 56.

[0045] The support mechanism 7 includes strips 71. Four strips 71 are fixedly installed between the front and rear sides of the inner wall of the rectangular groove 54. Two strips 71 form a group and are symmetrically distributed from left to right. A support rod 72 is fixedly installed on the top of the strips 71, which fits against the inner side of the guide sleeve 52 and is fixedly connected to the inner side of the mounting ring plate 51.

[0046] The strip plate 71 supports the filter screen 61 to prevent it from deforming or being damaged due to leakage pressure. There are four strip plates 71, which are arranged in pairs and symmetrically distributed from left to right to provide stable support. The support rod 72 connects the inner side of the strip plate 71 and the guide sleeve 52 to further enhance the stability of the support mechanism. It is fixedly connected to the inner side of the mounting ring plate 51 to ensure the overall stability of the support mechanism and the mounting mechanism 5.

[0047] The fixing mechanism 8 includes a wedge plate 81. Both sides of the support plate 53 are slidably installed with wedge plates 81 that extend into two mounting slots 56 and are attached to the top of the rectangular plate 62. Two mounting blocks 82 are fixedly installed on one side of the wedge plate 81. A fixing spring 83 that is fixedly connected to the outside of the support plate 53 is fixedly installed on one side of the mounting block 82. A U-shaped rod 84 is fixedly installed on one side of the wedge plate 81.

[0048] The wedge plate 81 is slidably installed on both sides of the support plate 53, extending into the mounting groove 56 and fitting against the top of the rectangular plate 62, fixing the position of the filter screen 61. The elastic force of the fixing spring 83 ensures that the wedge plate 81 and the rectangular plate 62 fit tightly together, preventing the filter screen 61 from loosening or falling off. The mounting block 82 and the fixing spring 83 connect the wedge plate 81 and the outside of the support plate 53, providing the mounting base for the fixing spring 83. The fixing spring 83 has good elasticity and durability, ensuring the stable fixing effect of the wedge plate 81. The U-shaped rod 84 is fixed on one side of the wedge plate 81, making it convenient for medical staff to operate the sliding of the wedge plate 81. Its shape conforms to the ergonomic design, making it easy to grip and operate.

[0049] When using the bag, check its integrity to ensure that no parts are damaged or missing. Clean the patient's skin and ensure that the application area is dry and free of grease and dirt. Peel off the protective paper on the back of the adhesive patch 1 to expose the medical pressure-sensitive adhesive layer. Align the bag with the exudate site and gently press the adhesive patch 1 to ensure it adheres tightly to the skin. The exudate will automatically enter the bag through the perforation. Medical staff can periodically observe the amount of exudate in the bag for timely replacement or drainage. During the collection process, the exudate will be filtered by the filtration mechanism 6. The support mechanism 7 will ensure the stability and filtration effect of the filtration mechanism 6. When the amount of exudate in the bag reaches a certain level, open the valve 42 to drain the exudate through the drain pipe 41. After drainage, close the valve 42 and continue collecting the exudate. When the amount of exudate in the bag approaches or reaches its maximum capacity, or when the bag needs to be replaced due to prolonged use, a new bag should be used. To replace the bag, first peel off the adhesive patch 1, then gently remove the old bag and re-attach the new bag following the steps described above.

[0050] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0051] In summary, by setting up the installation mechanism 5, the filtering mechanism 6, and the fixing mechanism 8, the filter screen 61 of the filtering mechanism 6 is embedded in the mounting groove 56 of the support plate 53 at both ends through the rectangular plate 62, forming a preliminary positioning. The wedge plate 81 of the fixing mechanism 8 is slidably installed on both sides of the support plate 53. The wedge plate 81 can be manually pushed inward by the U-shaped rod 84. The inclined surface of the wedge plate 81 is in contact with the top of the rectangular plate 62. When the wedge plate 81 slides inward, its inclined surface will press down on the rectangular plate 62, so that the edge of the filter screen 61 is tightly in contact with the inner wall of the rectangular groove 54. The fixing spring 83 connects the wedge plate 81 and the outside of the support plate 53, providing a reverse pulling force. When the U-shaped rod 84 is manually released, the spring 83 will pull the wedge plate 81 to slide outward, relieving the pressure on the rectangular plate 62, which facilitates the disassembly and replacement of the filter screen 61. The seepage enters the collection bag through the through hole of the adhesive patch 1 and the soft inner ring 22, and first contacts the guide sleeve 52. The guide sleeve 52 has a tapered structure that is wider at the top and narrower at the bottom, which guides the exudate to converge towards the center and reduces splashing. The exudate flows along the guide sleeve 52 into the rectangular groove 54 of the support plate 53. At this time, the filter screen 61 is placed horizontally in the rectangular groove 54 to filter the exudate. The filter screen 61 can effectively intercept impurities such as solid particles and tissue fragments in the exudate. The filtered exudate flows into the bottom of the collection bag through the drainage hole 55 at the bottom of the support plate 53, and is finally discharged through the discharge pipe 41. The edge of the filter screen 61 is tightly fitted with the inner wall of the rectangular groove 54 to prevent the exudate from flowing directly into the collection bag around the filter screen, ensuring the filtration effect and achieving the purpose of having a filtration structure. By setting up a support mechanism 7, the strip 71 of the support mechanism 7 is fixed to the rectangular groove. The inner walls of filter 61 are symmetrically distributed on both sides. Each group of two strips 71 jointly supports the middle area of ​​filter 61. The top of the strips 71 is fixedly connected to the inner side of the guide sleeve 52 and the inner side of the mounting ring plate 51 through the support rod 72, forming a stable triangular support structure, which enhances the overall rigidity. The support rod 72 ensures the normal use of the drainage channel and prevents the inner wall of the guide sleeve 52 from sticking together. This achieves the purpose of having a support structure and solves the problem that without a corresponding filter structure, it is impossible to block solids, flocculent materials, etc., which leads to easy blockage of the outlet and affects the use of the collection bag. In addition, without a support structure, the bag body cannot be effectively supported. If the membrane of the bag body sticks to the wall, it will affect the drainage effect.
