[0001] This utility model belongs to the field of liquid drainage technology, and more specifically, it relates to a drainage bag for collecting flushing fluid. Background Technology

[0002] In clinical surgery, wounds are frequently irrigated with irrigation fluid, which is then drained into a waste container using a drainage bag to prevent contamination of the surrounding surgical drapes. However, the irrigation fluid often contains valuable pathological specimens. Currently, drainage bags include a filter to collect these specimens, but this method results in significant specimen residue remaining on the inner wall of the drainage bag, leading to poor collection efficiency and difficulty in removing the specimens. Utility Model Content

[0003] The purpose of this invention is to provide a drainage bag for collecting rinsing fluid, so as to solve the technical problems of poor collection effect of pathological specimens and difficulty in removing pathological specimens from the drainage bag in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drainage bag for collecting rinsing fluid is provided, comprising a membrane, a collection chamber, a drainage tube, and a filtrate storage component; the collection chamber is fixedly installed on the membrane, and has an inlet and an outlet at its upper and lower ends respectively; the lower side of the collection chamber has a conical section that is wider at the top and narrower at the bottom, and the outlet is located at the lower end of the conical section; the drainage tube is fixedly installed on the collection chamber, and its upper end is connected to and communicates with the outlet; the filtrate storage component is installed in the outlet and is used to filter substances in the rinsing fluid and store pathological specimens; the filtrate storage component has a storage cylinder adapted to the inner wall of the drainage tube and a filter layer installed at the lower end of the storage cylinder.

[0005] In one possible implementation, the liquid collection chamber further includes a straight section located above the conical section, the lower end of the straight section being connected to the upper end of the conical section; the liquid inlet is located at the upper end of the straight section.

[0006] In one possible implementation, the upper end of the straight section is provided with a conformally arranged support wire.

[0026] Please see Figures 1 to 5The present invention provides a drainage bag for collecting rinsing fluid. A drainage bag for collecting rinsing fluid includes a membrane 10, a collection chamber 20, a drainage tube 30, and a filtrate storage container 40. The collection chamber 20 is fixedly installed on the membrane 10, and has an inlet 21 and an outlet 22 at its upper and lower ends, respectively. A conical section 23, wider at the top and narrower at the bottom, is provided on the lower side of the collection chamber 20, and the outlet 22 is located at the lower end of the conical section 23. The drainage tube 30 is fixedly installed on the collection chamber 20, and its upper end is connected to and communicates with the outlet 22. The filtrate storage container 40 is installed in the outlet 22 and is used to filter substances in the rinsing fluid and store pathological specimens. The filtrate storage container 40 has a storage cylinder 41 adapted to the inner wall of the drainage tube 30 and a filter layer 42 installed at the lower end of the storage cylinder 41.

[0027] Compared with the prior art, the irrigation fluid collection drainage bag provided by this utility model is used in a different way. During use, the entire drainage bag is adhered to the surgical site with the help of a film 10, so that the collection chamber 20 is located to the side or below the surgical incision. During the operation, the irrigation fluid flows smoothly through the inlet 21 of the collection chamber 20; then, through the conical section 23 in the collection chamber 20, the irrigation fluid flows towards the outlet 22, allowing it to first enter the filtrate storage container 40. Under the action of the filter layer 42, the pathological specimens in the irrigation fluid are blocked and stored in the storage cylinder 41, while the irrigation fluid enters the drainage tube 30 for discharge. After the operation, the filtrate storage container 40 can be removed from the collection chamber 20 to collect the pathological specimens. In this way, a larger amount of pathological specimens in the irrigation fluid enters the lower end of the collection chamber 20 and is collected in the storage cylinder 41. Furthermore, after the operation, the filtrate storage container 40 can be directly removed to collect the pathological specimens.

[0028] The conical section 23 allows for the smooth discharge of the rinsing fluid under gravity. The conical section 23, which is wider at the top and narrower at the bottom, allows the pathological specimens in the rinsing fluid to naturally collect in the storage cylinder 41, reducing residue on the inner wall of the collection chamber 20.

[0029] Please see Figures 1 to 3 As a specific embodiment of the flushing fluid collection drainage bag provided by this utility model, the collection chamber 20 further includes a straight section 24 located above the conical section 23, with the lower end of the straight section 24 connected to the upper end of the conical section 23; the inlet 21 is located at the upper end of the straight section 24; the straight section 24 allows the flushing fluid to pass through the inlet 21 and flow smoothly downwards along the straight section 24, enabling the flushing fluid to flow more smoothly into the collection chamber 20. A scale marking may be provided on the outside of the straight section 24, allowing the amount of liquid entering the collection chamber 20 to be visually observed. The straight section 24 is made of transparent high-strength plastic.

[0030] Please see Figures 1 to 4 As a specific embodiment of the flushing fluid collection drainage bag provided by this utility model, the upper end of the straight section 24 is provided with a conformally arranged support wire 25. Since the upper port of the straight section 24 is the liquid inlet 21, in order to ensure that the liquid inlet 21 does not deform and guide the flushing fluid into the collection chamber 20, the support wire 25 is arranged circumferentially along the upper end of the straight section 24, so that the upper end of the straight section 24 maintains its working shape and does not deform. The support wire 25 closely fits the shape of the straight section 24, giving the straight section 24 a stable support. Whether the straight section 24 is subjected to external pressure impact or its own deformation tendency under different environments, the support wire 25 can effectively resist and correct it. This allows the straight section 24 to always maintain its proper shape and structural integrity, ensuring that the entire drainage bag can be used normally and stably.

[0031] Please see Figures 1 to 4 As a specific embodiment of the flushing fluid collection drainage bag provided by this utility model, the straight cylindrical section 24 is provided with a sealing membrane 26 for surrounding the supporting metal wire 25; that is, by using the sealing membrane 26 to completely wrap the supporting metal wire 25, the corrosion of the supporting metal wire 25 by the external environment can be effectively prevented; similarly, it also prevents the supporting metal wire 25 from interfering with or affecting external factors. Specifically, the sealing membrane 26 is made of a material that is heat-resistant and has good flexibility.

[0032] Please see Figures 1 to 4 In one specific embodiment of the flushing fluid collection drainage bag provided by this utility model, the straight cylindrical section 24, the conical cylindrical section 23, and the sealing membrane 26 are integrally formed. The straight cylindrical section 24 and the sealing membrane 26 are used to accommodate the inner cavity 27 of the supporting metal wire 25. The integral forming method ensures high connection strength, stability, and sealing performance between the conical cylindrical section 23 and the straight cylindrical section 24. The sealing membrane 26 is a thickened layer on the outer wall of the straight cylindrical section 24, forming the inner cavity 27 inside the thickened layer, where the supporting metal wire 25 is installed. Because the inner cavity 27 formed by the straight cylindrical section 24 and the sealing membrane 26 has a regular shape, it can accurately accommodate the supporting metal wire 25, avoiding the displacement or damage of the supporting metal wire 25 that may occur due to the irregular shape of the inner cavity 27.

[0033] Please see Figure 2 and Figure 3 As a specific embodiment of the flushing fluid collection drainage bag provided by this utility model, the outer diameter of the storage cylinder 41 is larger than the inner diameter of the drainage pipe 30; this structure prevents the storage cylinder 41 from entering the drainage pipe 30 under the impact of the liquid, thus improving stability.

[0034] Please see Figure 5As a specific embodiment of the drainage bag for collecting rinsing fluid provided by this utility model, the upper end of the storage cylinder 41 is provided with a retaining ring 43 for installation or removal. When installing the storage cylinder 41 or removing the storage cylinder 41 from the collection chamber, a tool is used to act on the retaining ring 43, thereby more smoothly and stably removing the storage cylinder 41 and the pathological specimen located inside the storage cylinder 41. There are two retaining rings 43, which are symmetrically arranged on both sides of the upper end of the storage cylinder 41. The tool can be a hook or tweezers, etc.

[0035] As a specific embodiment of the flushing fluid collection drainage bag provided by this utility model, the inner wall of the drainage tube 30 is provided with a protrusion for limiting the filtrate storage component 40; the protrusion provides support and limits the filtrate storage component 40, thereby making the filtrate storage component 40 work more stably. Specifically, there are multiple protrusions, which are arranged at intervals along the circumference of the inner wall of the drainage tube 30, so that the filtrate storage component 40 is subjected to uniform force.

[0036] Please see Figure 1 , Figure 2 and Figure 5 As a specific embodiment of the flushing fluid collection drainage bag provided by this utility model, the storage cylinder 41 has a steel ring structure. This structure simplifies the structure of the filtrate storage component 40 and provides high overall strength and stability. Simultaneously, the filter layer 42 using a filter screen effectively screens the material, preventing pathological specimens from entering the drainage tube 30. The steel ring is a solid structure, ensuring effective storage of pathological specimens.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
