Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically a drainage filter device and a drainage kit. Background Technology

[0002] Drainage is a surgical treatment method that includes external drainage and internal drainage. External drainage involves using drainage tubes to transfer pus, blood, and other fluids accumulated between body tissues, outside body cavities, and inside internal organs to the outside of the body. Examples of external drainage include thoracic drainage, abdominal drainage, biliary drainage, nephrostomy, cystostomy, and urine drainage.

[0003] During drainage, a surgical incision or puncture site needs to be created in the skin to allow the drainage tube to be inserted into the body. However, due to the influence of factors such as the body's immune response and its own tissue fluid, the effusion contains a lot of protein and other components. When the effusion flows to the outside through the drainage tube, the protein and other components in the effusion can easily accumulate in the drainage tube and at the valve body that controls the opening and closing of the drainage tube, thereby blocking the tube and affecting the drainage of the effusion and the opening and closing of the valve body. Utility Model Content

[0004] To reduce the possibility of blockage in the drainage tubing and to prevent protein from accumulating in the fluid at the valve body and affecting its operation, this application provides a drainage filter device and a drainage kit.

[0005] A filtration device for drainage includes: a housing having a filtration chamber inside, and an inlet and an outlet connecting the outside to the filtration chamber; a partition having multiple receiving grooves on its top and bottom surfaces, the filtration chamber having multiple partitions arranged in an array along the thickness direction of the partitions, adjacent partitions having a gap, and working sections formed between adjacent partitions and between the partitions and the top and bottom walls of the filtration chamber, the partitions having a first opening, the projections of the two first openings of adjacent partitions onto one of the partitions being located at both ends of the length direction of the partition, and the working sections being connected in series through the first openings to form a liquid channel for liquid flow, the two ends of the liquid channel being connected to the inlet and the outlet respectively.

[0006] In one embodiment of this application, the outer shell includes a main body and a cover connected to the main body. The cover is movably connected to the main body and can open or close the filter chamber. The drainage filter device also includes a frame, with each partition fixedly connected to the frame and the frame detachably connected to the filter chamber.

[0007] A drainage kit includes a drainage filter device, which includes a housing with a filter chamber inside, and an inlet and an outlet connecting the filter chamber to the outside. A partition has multiple receiving grooves on its top and bottom surfaces. Multiple partitions are arranged in an array along the thickness direction of the partitions, with gaps between adjacent partitions. Working sections are formed between adjacent partitions and between the partitions and the top and bottom walls of the filter chamber. Each partition has a first opening, and the projections of two first openings of adjacent partitions onto one of the partitions are located at opposite ends of the partition's length. Each working section is connected in series through the first openings to form a liquid channel for liquid flow, with both ends of the liquid channel connected to the inlet and outlet, respectively. The housing includes a main body and a cover connected to the main body. The cover is movably connected to the main body and can open or close the filter chamber. The drainage filter device also includes a frame, with each partition fixedly connected to the frame, and the frame detachably connected to the filter chamber. The drainage kit also includes a flexible main pipe that connects to the inlet, and the main pipe is also equipped with a tubing stop hose clamp.

[0008] In one embodiment of this application, the drainage kit further includes a three-way valve and two flexible branch lines, with the inlet of the three-way valve connected to the outlet and the two outlets of the three-way valve respectively connected to the two branch lines.

[0009] In one embodiment of this application, the three-way valve includes a valve core and a valve body, with the valve core and valve body being threadedly connected.

[0010] In one embodiment of this application, one end of the branch pipeline is connected to the outlet of the three-way valve, and the other end is detachably connected to a protective cap.

[0011] In one embodiment of this application, the drainage kit further includes a drainage bottle, which is detachably connected to one of the branch lines.

[0012] In one embodiment of this application, a negative pressure drainage ball is connected to the top of the drainage bottle.

[0013] In one embodiment of this application, the wall of the drainage bottle is provided with a capacity scale.

[0014] In one embodiment of this application, the main pipeline is a transparent pipeline.

[0015] The beneficial effects of this application are at least as follows:

[0016] 1. Because the partition has a receiving groove, when the liquid flows through the filter chamber, the proteins and other substances in the liquid can be retained in the receiving groove, reducing the accumulation of proteins and other substances in the pipeline and avoiding pipeline blockage. At the same time, the presence of the first opening on the partition allows the viscous liquid to flow more smoothly in the filter chamber.

[0017] 2. The filter chamber can be opened or closed, and the frame and filter chamber are detachably connected. The partition connected to the frame can be removed from the filter chamber for cleaning. Attached Figure Description

[0033] Please see Figures 1 to 7 Learn more about this application.

[0034] See Figure 1 , Figure 2 , Figure 3 A drainage filtration device includes a housing 101 and a partition 202. The housing has a filtration chamber, an inlet 104, and an outlet 105 connecting the filtration chamber to the outside. The partition 202 has multiple receiving grooves 204 on its top and bottom surfaces. The filtration chamber contains multiple partitions 202 arranged in an array along its thickness direction. Adjacent partitions 202 are spaced apart. A partition 202 adjacent to the top wall of the filtration chamber is spaced apart from the top wall, and a partition 202 adjacent to the bottom wall of the filtration chamber is spaced apart from the bottom wall. These spaces, along with the spaces between adjacent partitions 202 and the top wall of the filtration chamber, and between the partitions 202 and the bottom wall of the filtration chamber, form a working section 205. Each partition 202 has a first opening 203. The projections of the two first openings 203 of adjacent partitions 202 onto one of the partitions 202 are located at both ends of the length of the partition 202. This results in opposite liquid flow directions in the working sections 205 on the upper and lower sides of the same partition 202. The working sections 205 are connected in series through the first openings 203 to form a liquid channel for liquid flow. The partitions 202 and the wall of the filter chamber form a liquid channel for accumulated liquid flow. The two ends of the liquid channel are connected to the inlet 104 and the outlet 105, respectively. The accumulated liquid entering the filter chamber through the inlet 104 can pass through multiple partitions 202. The receiving tanks 204 of the partitions 202 collect easily accumulated substances such as proteins in the accumulated liquid, preventing blockages from accumulating in other parts of the pipeline and affecting the flow of the accumulated liquid in the pipeline. (See also...) Figure 4 When a large blockage enters between the two baffles 202, the large blockage can get stuck between the two baffles 202. At the same time, the baffles are set with a large width, so that the working section 205 is wide. Even if the large blockage is stuck in the working section 205, the working section 205 still has pores for liquid to flow through, avoiding the large blockage from blocking the liquid channel. Preferably, the flow cross-sectional area of ​​the liquid channel gradually decreases.

[0035] See Figure 1 , Figure 3 In one embodiment of this application, the outer shell 101 includes a main body 102 and a cover 103 connected to the main body 102. The cover 103 is movably connected to the main body 102. For example, the cover 103 is detachably connected to the main body 102 through a snap-fit ​​structure or a pin hole structure, so that the cover 103 can open or close the filter chamber. The drainage filter device also includes a frame 201. Each partition 202 is fixedly connected to the frame 201. The frame 201 is detachably connected to the filter chamber. For example, when the frame 201 is placed in the filter chamber, the cover 103 and the main body 102 clamp the frame 201, thereby realizing the detachable connection between the frame 201 and the filter chamber. Of course, the frame 201 can also achieve the detachable connection with the filter chamber through a snap-fit ​​structure or a threaded connection structure, which will not be described in detail here.

[0036] See Figure 5 A drainage kit includes a drainage filter device and a flexible main pipeline 301 connected to an inlet 104. The main pipeline 301 is also equipped with a conduit stop hose clamp 302. The drainage filter device includes a housing 101 with a filter chamber inside, and an inlet 104 and an outlet 105 connecting the filter chamber to the outside. A partition 202 has multiple receiving grooves 204 on its top and bottom surfaces. Multiple partitions 202 are arranged in an array within the filter chamber, arranged along the thickness direction of each partition 202. Adjacent partitions 202 are spaced apart, and working sections 2 are formed between adjacent partitions 202 and between the partitions 202 and the top and bottom walls of the filter chamber. 05. The partition 202 is provided with a first opening 203. The projections of the two first openings 203 of adjacent partitions 202 on one of the partitions 202 are located at both ends of the length direction of the partition 202. Each working section 205 is connected in series through the first opening 203 to form a liquid channel for liquid flow. The two ends of the liquid channel are connected to the liquid inlet 104 and the liquid outlet 105 respectively. The outer shell 101 includes a main body 102 and a cover 103 connected to the main body 102. The cover 103 is movably connected to the main body 102 and can open or close the filter chamber. The drainage filter device also includes a frame 201. Each partition 202 is fixedly connected to the frame 201, and the frame 201 is detachably connected to the filter chamber.

[0037] When the main tube 301 is inserted into the patient's chest cavity or other locations, the main tube 301 can be sealed by the catheter closure hose clamp 302. Then, the cover 103 and the main body 102 are separated, the partition 202 is removed, and the partition 202 and the filter chamber are cleaned to prevent excessive blockage from affecting the flow of fluid in the tube. In one embodiment of this application, the main tube 301 is a transparent tube, which facilitates observation of the situation in the main tube 301.

[0038] In one embodiment of this application, the diameter of the main pipeline 301 is 5 mm to 13 mm.

[0039] See Figure 5 In one embodiment of this application, the drainage kit further includes a three-way valve 401 and two flexible branch pipes. The inlet of the three-way valve 401 is connected to the outlet 105, and the two outlets of the three-way valve 401 are respectively connected to the two branch pipes. For better description of this application, the two branch pipes are named the first branch 303 and the second branch 304. One end of each branch pipe is connected to the outlet of the three-way valve 401, and the other end is detachably connected to a protective cap 305. See [link to relevant documentation]. Figure 5 The second branch 304 is connected to a protective cap 305. There are various ways to achieve the detachable connection between the branch pipeline and the protective cap 305, such as threaded connection or snap-fit ​​connection between the branch pipeline and the protective cap 305. The protective cap 305 can prevent external pollutants from entering the branch pipeline.

[0040] See Figure 6 In one embodiment of this application, the three-way valve 401 includes a valve core 403 and a valve body 402. The valve core 403 and the valve body 402 are threadedly connected so that the valve core 403 and the valve body 402 can be separated during use to facilitate cleaning of the three-way valve 401.

[0041] The drainage kit also includes a drainage bottle 306, which is detachably connected to one of the branch lines via a threaded or plug-in connection. See [link to details]. Figure 5 The drainage bottle 306 is connected to the outlet of the three-way valve 401 via the first branch 303. When cleaning the drainage bottle 306 is required, the three-way valve 401 is used to disconnect the first branch 303 from the main pipeline 301, separating the drainage bottle 306 from the first branch 303. The first branch 303 and the protective cap 305 are then connected for cleaning. Furthermore, the drainage bottle 306 has volume markings on its wall for easy observation of the amount of fluid in the bottle, allowing for assessment of the patient's condition and timely emptying of the fluid as needed. By connecting the main pipeline 301 to the first branch 303 and the second branch 304 via the three-way valve 401, medical staff can open or disconnect the connection between the main pipeline 301 and the first branch 303, the main pipeline 301 and the second branch 304, and the first branch 303 and the second branch 304 as needed. Alternatively, the main pipeline 301 can be directly closed and not connected to other branch pipelines. Medical staff can connect the main pipeline 301 to the second branch 304 to sample the accumulated fluid, or they can use the catheter stop hose clamp 302 to close the main pipeline 301 and connect the first branch 303 and the second branch 304 to flush the first branch 303, the three-way valve 401, and the second branch 304 with liquid.

[0042] See Figure 7 In one embodiment of this application, a negative pressure drainage ball 307 is connected to the top of the drainage bottle 306. The negative pressure drainage ball 307 can draw liquid from the pipeline, allowing the liquid to enter the drainage bottle 306, which facilitates the collection of accumulated liquid and pipeline flushing fluid.
