Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a device for collecting leakage liquid at a percutaneous outlet of a drainage tube. Background Art

[0002] In clinical practice, surgeons place indwelling drainage tubes after abdominal surgeries, such as those involving the liver or pancreas, to drain excess or harmful fluids, such as pus, blood, and exudate, from tissues or cavities to the outside of the body. This helps promote wound healing and prevent postoperative infection. Furthermore, the color and properties of the drained fluid are observed to assess postoperative complications such as bleeding, anastomotic leakage, and infection. However, a common problem is persistent leakage from the percutaneous exit site of the abdominal drain due to various factors, including excessive intraperitoneal fluid pressure, poorly sutured percutaneous exit sites, changes in the patient's condition, or postoperative complications. For example, ascites caused by hypoproteinemia, liver failure, and various anastomotic leakages can cause fluid to leak from around the drainage tube opening.

[0003] Percutaneous exudates from abdominal drainage tubes primarily include ascites, bile, gastrointestinal fluid, pus, and other fluids requiring proper management. These acidic or alkaline exudates can cause persistent and adverse irritation to the skin surrounding the outlet, leading to redness, swelling, dermatitis, and even ulceration. Furthermore, they can contaminate dressings, clothing, and bedding surrounding the drainage outlet, necessitating multiple daily (3–5 times / day, or even more) changes of wound dressings, clothing, and bedding. This not only increases the risk of wound infection and the financial and psychological burden on patients, but also increases the workload of medical staff and the department's laundry costs.

[0004] To solve the problem of extravasation of drainage fluid from the percutaneous opening of the abdominal drainage tube after abdominal surgery, the methods commonly used in clinical nursing are:

[0005] 1) After the patient has an indwelling drainage tube, gauze or other dressings are covered around the exposed percutaneous exit of the drainage tube to absorb the exudate, and the tube is fixed to the patient's skin with butterfly wings.

[0006] 2) Use of colonic, ileal, or urostomy bags to collect exudate at the percutaneous site of the drainage tube and modification of these bags with a hand-cut hole in the bag to allow the drainage tube to pass through.

[0007] Since the drainage tubes used clinically vary in size and material properties, existing technical means are difficult to meet clinical application needs.

[0008] 1) When there is a lot of exudate around the drainage tube, the use of auxiliary material absorption methods is limited in effectiveness and can easily cause infection and discomfort to the skin around the drainage tube. For example, current clinical nursing practices typically use gauze to cover the ascites puncture site to treat the exudate. However, this gauze covering method requires frequent gauze changes and is prone to falling off. When using gauze, the odor of the exudate from the ascites puncture site spreads into the air, causing discomfort. In addition, long-term moisture in the dressing can easily cause skin infection in patients, leading to skin flushing, erosion, and even ulcers, causing harm and pain to the patient. Therefore, using a drainage tube alone still fails to alleviate the patient's pain, prolongs treatment time, and places a financial and mental burden on the patient. Continuous exudate from the drainage tube requires doctors to constantly change dressings and nurses to replace contaminated bedding, increasing their workload.

[0009] 2) Using existing ostomy bags, manually cutting a hole to pass the drainage tube through, and then tying it with string or tape also fails to address the problem of leaking fluid. To manage leaking fluid from the drainage tube opening, clinical practice currently involves cutting a small opening in the bag (through which the drainage tube passes) to collect it. However, the hole cut in the back of the bag to accommodate the drainage tube is handmade, so it can be too large or too small. Furthermore, fitting the drainage tube through these irregular holes often results in a poor fit. Therefore, modified ostomy bags must be tied with string or taped with thick glue or transparent patches, but these methods offer poor fixation and a loose fit. Once the patient gets out of bed, exudate often leaks from the small opening, contaminating clothing and bedding, making care more difficult for medical staff.

[0010] 3) Specially designed drainage connection devices with ostomy bags are difficult to connect because the diameters of drainage tubes vary. In addition, this type of device is generally designed with only one external drainage connection tube, so the clinical application of drainage connection devices is limited and the cost is relatively high.

[0011] 4) Adding an inflation sealing hole to the ostomy bag allows drainage tubes of different diameters to pass through the bag and be sealed, but the inflation sealing structure is relatively complex, which increases the manufacturing cost of the product and the financial burden on the patient. It is also unreliable and cumbersome to operate.

[0012] 5) The openable sealing window on the existing ostomy bag is a semi-rigid plastic structure, which is relatively hard and often feels like a foreign body when worn on the patient. Utility Model Content

[0066] The following combination Figures 1 to 13 The present invention is described in detail with specific implementation methods.

[0067] In some specific embodiments of the present invention, Figures 1 to 13 As shown, the present invention provides a device for collecting leakage at the percutaneous outlet of a drainage tube, comprising: a collection bag 10, comprising a first body 11 and a second body 12 arranged opposite to each other, a receiving cavity 15 for receiving leakage formed between the first body 11 and the second body 12, and a first opening 13 is provided on the first body 11, and a second opening 14 is provided on the second body 12; an operation window 20, connected to a side of the first body 11 facing away from the second body 12, and arranged corresponding to the first opening 13; an adhesive plate 30, connected to a side of the second body 12 facing away from the first body The first body 11 is connected to one side of the second body 12 and is provided corresponding to the second opening 14; the elastic perforated membrane 40 is provided on the side of the first body 11 having the operation window 20, and is spaced apart from the operation window 20 along the first direction N. The elastic perforated membrane 40 is provided with a through hole 41, and the through hole 41 forms an elastic sealed channel for the drainage tube 50 to pass through. The first direction N is perpendicular to the direction connecting the first body 11 and the second body 12; wherein, after passing through the skin, the drainage tube 50 passes through the adhesive plate 30, the accommodating cavity 15 and the through hole 41 in sequence, and is connected to the external drainage bag.

[0068] It should be noted that the present invention completely solves the problem of leakage of exudate that may occur when drainage tubes 50 of various diameters pass through the collection bag 10 by providing the elastic perforated membrane 40 .

[0069] Furthermore, the natural form mentioned in the present invention refers to the form of the through hole 41 when the flow tube 50 passes through the through hole 41 .

[0070] Furthermore, the collection bag 10 of the present invention can reduce the risk of skin infection around the opening of the drainage tube 50, increase the comfort of the patient, and reduce the workload of medical staff in changing dressings and bedding, thereby saving medical resources.

[0071] In a possible embodiment, the collecting bag 10 is arranged in an inverted pear shape and is used to collect and store the leaked liquid.

[0072] In a possible embodiment, the number of the drainage tubes 50 ranges from 1 to 5.

[0073] In a possible embodiment, a variety of drain tube 50 connections can be configured to address the issue of maintaining a seal when drain tubes 50 of varying outer diameters are passed through the exudate collection bag 10. The use of the collection bag 10 does not affect the sterile, sealed drainage of the existing drain tube 50, and allows medical staff to better collect and observe the color, properties, and flow rate of the exudate. While effectively collecting exudate around the drain tube 50, it also reduces contamination of the skin, dressings, clothing, and other items, minimizing patient discomfort, the risk of skin infections, and the financial burden of frequent dressing changes. This avoids the increased need for clothing and bedding changes caused by exudate, reducing the workload of medical staff.

[0074] In some possible embodiments of the present invention, the elastic perforated membrane 40 is provided with a through hole 41;

[0075] Alternatively, the elastic perforated membrane 40 is provided with at least two through holes 41 , wherein the apertures of all the through holes 41 are the same or the apertures of all the through holes 41 have at least two sizes.

[0076] Specifically, this embodiment provides an implementation of a through hole 41. The setting of one or more through holes 41 can simultaneously accommodate one or more drainage tubes 50 passing through the collection bag 10, and an operation window 20 is provided to facilitate operation and daily cleaning and maintenance of the drainage port.

[0077] In some possible implementations of the present invention, the first body 11 and the second body 12 are transparent containing structures connected by ultrasonic welding (thermal fusion) or strong adhesive.

[0078] Specifically, this embodiment provides an implementation method of the connection between the first body 11 and the second body 12. By arranging the first body 11 and the second body 12 to be ultrasonically welded, the collecting bag 10 can form a receiving cavity 15 for receiving the leaked liquid.

[0079] In some possible implementations of the present invention, an isolation layer made of a flexible material is provided on a surface of the first body 11 facing away from the second body 12 , and on a surface of the second body 12 facing away from the first body 11 .

[0080] Specifically, this embodiment provides an implementation method of an isolation layer, in which an isolation layer is arranged on the outside of the first body 11 and the second body 12, so that the collection bag 10 can provide the patient with a better contact experience during the contact with the patient's skin, improve the patient's comfort, and at the same time improve the strength of the collection bag 10.

[0081] In a possible embodiment, the isolation layer is a soft nonwoven fabric.

[0082] In some possible implementations of the present invention, the adhesive plate 30 is an adhesive component made of a breathable and waterproof wound adhesive material.

[0083] Specifically, this embodiment provides an implementation of an adhesive plate 30, which is made of a breathable and waterproof wound adhesive material. When the collection bag 10 is attached to the patient's skin, it can effectively prevent the exudate from infecting the patient's skin.

[0084] In some possible embodiments of the present invention, it also includes: a connecting valve 60, which is arranged at the end of the collecting bag 10 along the first direction N; a check valve 70, which is arranged in the accommodating chamber 15 and divides the accommodating chamber 15 into a first chamber 16 and a second chamber 17, the drainage tube 50 passes through the first chamber 16, and the connecting valve 60 is connected to one side of the second chamber 17; wherein the check valve 70 includes a conductive state for allowing leakage liquid to flow from the first chamber 16 into the second chamber 17, and a closed state for preventing leakage liquid from flowing back from the second chamber 17 to the first chamber 16.

[0085] Specifically, this embodiment provides an implementation of a connecting valve 60 and a check valve 70 . The connecting valve 60 is located at the end of the collecting bag 10 and at the bottom of the entire collecting bag 10 , and is used to discharge the leaked liquid in the accommodating cavity 15 .

[0086] Furthermore, the check valve 70 is a thin film structure, which is arranged inside the accommodating chamber 15 and divides the accommodating chamber 15 into a first chamber 16 and a second chamber 17, and is used to prevent the collected exudate from flowing back due to changes in the patient's body position, thereby soaking the skin around the patient's wound, further reducing the risk of the exudate soaking the skin around the drainage tube 50 and leaking from the bag of the drainage tube 50.

[0087] It should be noted that the connecting valve used at the bottom of the collection bag 10 can further prevent leakage of exudate during emptying and sampling, effectively avoiding the risk of skin infection at the patient's drainage port, improving the patient's hygiene and comfort, and reducing nursing workload and costs.

[0088] In a possible embodiment, the connecting valve 60 is provided with a Luer connection thread to facilitate connection with an automatic drainage (or exudate) monitoring device and minimize the risk of leakage of the collected exudate during operations such as emptying and sampling.

[0089] In some possible embodiments of the present invention, the operating window 20 includes: a window seat 21, which is connected to the first body 11 and is provided with an operating port 22; a window cover 23, which is detachably connected to the window seat 21 corresponding to the operating port 22; wherein the window seat 21 and the window cover 23 are both sheet structures made of flexible material.

[0090] Specifically, this embodiment provides an implementation method of an operating window 20. By setting a window seat 21 and a window cover 23, medical staff can perform daily cleaning and maintenance of the drainage port through the operating window 20. At the same time, the window seat 21 and the window cover 23 are detachably connected, reducing the difficulty of operation.

[0091] Furthermore, the window seat 21 and the window cover 23 are made of flexible ultra-thin materials, which facilitates the patient to put on and turn over, and improves wearing comfort while preventing drainage fluid leakage.

[0092] In some possible embodiments of the present invention, a first annular sealing groove 211 and a second annular sealing groove 212 are provided on one side surface of the window seat 21 facing the window cover 23. The first annular sealing groove 211 and the second annular sealing groove 212 are annular sealing structures, and the groove-shaped openings of the first annular sealing groove 211 and the second annular sealing groove 212 face one side of the window cover 23; the window cover 23 is provided with a first sealing protrusion 231 and a second sealing protrusion 232, and the first sealing protrusion 231 is plugged into and fitted with the groove-shaped opening of the first annular sealing groove 211, and the second sealing protrusion 232 is plugged into and fitted with the groove-shaped opening of the second annular sealing groove 212; wherein, the diameter of the first annular sealing groove 211 is smaller than the diameter of the second annular sealing groove 212.

[0093] Specifically, this embodiment provides an implementation method of a window seat 21 and a window cover 23. By setting a first annular sealing groove 211 and a second annular sealing groove 212, and corresponding first sealing protrusions 231 and second sealing protrusions 232, a double-ring sealing structure is formed. The window seat 21 and the window cover 23 are sealed and detachable by plugging and fitting the protrusions and the grooves.

[0094] Furthermore, the window seat 21 and the window cover 23 provided by the present invention can be quickly and conveniently closed and opened repeatedly, and ensure that no liquid leaks occur when the operating window 20 is closed.

[0095] In a possible embodiment, in addition to the double-ring first sealing protrusion 231 and the second sealing protrusion 232 on the side of the window cover 23 facing the window seat 21, a thin transparent structure is provided on the side of the window cover 23 facing away from the window seat 21, so as to facilitate clearer observation of the interior of the accommodating cavity 15 from the outside.

[0096] In a possible embodiment, Figure 8 and Figure 9 As shown, the window cover 23 and the thin transparent structure are detachably connected, for example, by bonding, and a simple operation can be performed by separating the window cover 23 from the thin transparent structure without disassembling the window cover 23 and the window seat 21.

[0097] In a possible embodiment, the window cover 23 and the thin transparent structure are an integrated structure. Figure 8 and Figure 9 In the figure, the positions of the window cover 23 and the transparent sheet are shown only to more clearly show the first sealing protrusion 231 and the second sealing protrusion 232 on the window cover 23, and does not mean that the window cover 23 and the transparent sheet are separate structures.

[0098] In some possible implementations of the present invention, the first annular sealing groove 211 , the second annular sealing groove 212 , the first sealing protrusion 231 , and the second sealing protrusion 232 are all sealing structures made of flexible materials.

[0099] Alternatively, the first annular sealing groove 211 is a sealing groove structure made of a material with less flexibility than the second annular sealing groove 212 , and the first sealing protrusion 231 is a rib-like structure made of a material with less flexibility than the second sealing protrusion 232 .

[0100] Alternatively, the first annular sealing groove 211 is a sealing groove structure made of a material with less flexibility than the second annular sealing groove 212 , and the first sealing protrusion 231 is a rib-like structure made of a material with greater flexibility than the second sealing protrusion 232 .

[0101] Alternatively, the first annular sealing groove 211 is a sealing groove structure made of a material with greater flexibility than the second annular sealing groove 212 , and the first sealing protrusion 231 is a rib-like structure made of a material with less flexibility than the second sealing protrusion 232 .

[0102] Specifically, this embodiment provides an implementation method for the structural form of a first annular sealing groove 211, a second annular sealing groove 212, a first sealing protrusion 231 and a second sealing protrusion 232. By setting flexible multiple forms of differences in the cooperation between the first annular sealing groove 211, the second annular sealing groove 212, the first sealing protrusion 231 and the second sealing protrusion 232, the sealing effect between the window seat 21 and the window cover 23 is improved, thereby preventing leakage of seepage liquid from between the window seat 21 and the window cover 23.

[0103] In some possible embodiments of the present invention, it further includes: an adhesive connecting layer 45, which is arranged between the elastic perforated membrane 40 and the first body 11; wherein the through hole 41 is a through hole; when the drainage tube 50 does not pass through the through hole 41, the first body 11 realizes the sealing of the accommodating cavity 15.

[0104] Specifically, this embodiment provides an implementation method of the through hole 41. By setting the through hole 41 as a through hole, the passage of the drainage tube 50 is facilitated, and by setting the adhesive connecting layer 45, the elastic perforated membrane 40 and the first body 11 are connected, and when the drainage tube 50 does not pass through, the first body 11 itself achieves sealing of the accommodating cavity 15.

[0105] In a possible embodiment, the diameter of the through hole 41 is between 1 mm and 5 mm.

[0106] In a possible embodiment, according to clinical needs, the diameters of the through holes 41 may be the same or different.

[0107] In a possible embodiment, the elastic perforated membrane 40 is made of a highly elastic medical synthetic material such as modified TPE, and is fixedly connected to the lower portion of the first opening 13 of the first body 11 of the collecting bag 10 by ultrasonic welding (thermal fusion) or strong adhesive.

[0108] In a possible embodiment, the diameter of the drainage tube 50 is between 2 mm and 10 mm.

[0109] In a possible embodiment, the elastic perforated membrane 40 has a shape of any one of square, circle, and triangle.

[0110] In a possible embodiment, the through holes 41 on the elastic perforated membrane 40 may be distributed on the same horizontal line or at a certain angle, for example, three through holes 41 may be distributed in a straight line or in a triangular shape.

[0111] In some possible embodiments of the present invention, the elastic perforated membrane 40 includes: a membrane body gap 42, which is arranged in the elastic perforated membrane 40 corresponding to the through hole 41, and divides the through hole 41 into a first hole position 43 and a second hole position 44; the first hole position 43 and the second hole position 44 are connected to form a through hole 41, and the through hole 41 includes a sealed state in a natural form and an open state when the drainage tube 50 passes through; wherein, the first hole position 43 is a through hole, the second hole position 44 is a countersunk hole, and an elastic film 46 is arranged in the second hole position 44; or, the first hole position 43 is a countersunk hole, the second hole position 44 is a through hole, and an elastic film 46 is arranged in the first hole position 43.

[0112] Specifically, this embodiment provides an implementation method of an elastic perforated membrane 40. When it is necessary to increase the sealing effect, a membrane gap 42 is set in the elastic perforated membrane 40, and the through hole 41 is divided to form a first hole position 43 and a second hole position 44, and the first hole position 43 and the second hole position 44 are provided with a structural combination of through holes and countersunk holes to improve the sealing. At the same time, the membrane gap 42 can ensure that the drainage tube 50 can obtain a certain deformation when passing through the first hole position 43 and the second hole position 44, thereby improving the sealing strength between the elastic perforated membrane 40 and the drainage tube 50.

[0113] It should be noted that when there is no drainage tube 50 passing through, the through hole 41 is in a sealed state. It can be understood that due to the action of the elastic film 46, the through hole 41 is in a sealed state in its natural form. When the drainage tube 50 passes through the through hole 41, the elastic film 46 is punctured by the drainage tube 50, and the elastic film 46 hugs the drainage tube 50 to achieve sealing.

[0114] Furthermore, when the drainage tube 50 is pulled out, the elastic film 46 can achieve sealing due to its own elasticity, that is, the elastic perforated film 40 can be reused.

[0115] Furthermore, the through hole 41 has two forms: a through hole and a semi-through countersunk hole. However, no matter what state the through hole 41 is in, a layer of elastic film 46 is arranged in the through hole 41. The elastic film 46 comes from the elastic perforated membrane 40, that is, the elastic film 46 is part of the elastic perforated membrane 40. Therefore, when there is no drainage tube 50 passing through, no leakage will occur in the through hole 41.

[0116] In a possible embodiment, the elastic perforated membrane 40 has a shape of any one of square, circle, and triangle.

[0117] In a possible embodiment, the through holes 41 on the elastic perforated membrane 40 may be distributed on the same horizontal line or at a certain angle, for example, three through holes 41 may be distributed in a straight line or in a triangular shape.

[0118] In a possible embodiment, the remaining thickness of the elastic perforated membrane 40 at the bottom of the semi-through countersunk hole is between 0.1 mm and 0.25 mm.
