[0012] According to some embodiments of this application, the leachate collection bag further includes a third bag body, which is connected to the third interface and is used to collect the leachate.
[0013] According to some embodiments of this application, the first bag is marked with scale lines, which are used to indicate the volume of the exudate collected in the first bag.
[0014] According to some embodiments of this application, the adhesive tray includes: an adhesive base having an adhesive surface and a through hole formed in the middle of the adhesive base; and a cutting tray disposed within the through hole and having a spirally extending cutting line along which the cutting tray can be cut.

[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0035] The following is for reference. Figures 1-7 The exudate collection bag 100 according to an embodiment of the present application is used to collect the exudate 400 of a patient 200, and a drainage device 300 is provided at the affected area of the patient 200. The exudate collection bag 100 can collect the exudate 400 that oozes from the affected area of the patient 200.
[0036] Currently, in the field of medical technology, surgical drainage is a treatment method and one of the most important surgical techniques, playing a crucial role in clinical practice. Surgical drainage is widely used in clinical practice as an important treatment and adjunctive therapy, primarily for draining accumulated air or fluid from body cavities, lavage of cavities, and monitoring of the patient's condition, in order to relieve symptoms, prevent or control infection, promote recovery, reduce pain, and improve the patient's quality of life.
[0037] The drainage device 300 should maintain the airtightness of the drainage tube 301, allowing the drainage fluid to be drawn out of the body along the lumen of the drainage tube 301. However, in actual operation, leakage from the drainage tube 301 at the patient's incision site 200 is often encountered. This usually includes the following situations: blockage within the lumen, poor drainage, and leakage from the periphery of the drainage tube 301 due to excessive local fluid pressure; poor sealing at the drainage tube 301, such as an excessively large incision, loosening or dislodging of sutures, etc.; prolonged indwelling drainage time, causing the drainage tube 301 to compress surrounding tissues and loosen at the tube opening; infectious drainage, corrosion of normal tissues, etc.
[0038] It should be noted that when there is exudation at the patient's surgical site (i.e., the surgical incision), at least the following problems exist: It increases the clinical workload of medical staff and the need for more medical consumables, such as the need for frequent dressing changes to keep the drainage device 300 and the surgical incision dry; it affects the patient's comfort and can easily lead to other complications, such as the exudate 400 causing the patient's skin to become moist (risk of eczema), reducing the patient's comfort and affecting postoperative recovery; it increases the risk of infection, such as bacterial growth at the site, increasing the risk of surgical site infection; it makes drainage measurement difficult, as most patients with drainage devices 300 require precise measurement of the drainage volume for timely feedback on subsequent treatment; inaccurate drainage will render it useless in guiding subsequent treatment; and it increases the difficulty of nursing care. Therefore, it is necessary to install an exudate collection device to collect the exudate 400 generated at the patient's surgical site to solve the above-mentioned technical problems.
[0039] In related technologies, existing exudate collection devices are mainly used for abdominal and pelvic drainage. These areas (i.e., the aforementioned abdominal and pelvic cavities) mainly involve fluid drainage, so there are no special requirements for whether or not the drainage device 300 needs to be retained. However, for areas where the collection of exudate 400 at which the drainage device 300 needs to be retained is strictly required, existing exudate collection devices are prone to interference with the drainage device 300, making it impossible to collect the exudate 400 while retaining the drainage device 300.
[0040] The aforementioned "strict requirement to retain the drainage device 300" includes, but is not limited to: closed chest drainage, drainage with a negative pressure device, etc. Taking closed chest drainage as an example, while ensuring the airtightness of the chest cavity, it is necessary to ensure that the position of the drainage device 300 drawn from the patient 200 remains unchanged. In other words, when the exudate collection device is attached to the patient 200, the drainage device 300 cannot be moved.
[0041] like Figure 1 As shown in this application, the leachate collection bag 100 includes a first bag body 1 and a second bag body 2.
[0042] Combination Figure 2 and Figure 3 As shown, the first bag body 1 is provided with an adhesive tray 11, which is used to adhere to the skin of the patient 200. The adhesive tray 11 can also be used for the drainage device 300 to pass through, and the first bag body 1 is used to collect exudate 400.
[0043] The adhesive tray 11 is attached to the skin of the patient 200 to fix the first bag 1 to the skin of the patient 200, so that the exudate 400 oozing from the patient 200 at the affected area can be collected in the first bag 1, and the adhesive tray 11 can be used for the drainage device 300 to pass through, so that the adhesive tray 11 can avoid the drainage device 300.
[0044] Combination Figure 1 and Figure 2 As shown, the first bag body 1 is provided with a first docking part 12, which forms a first pair of interfaces 121 opposite to the adhesive tray 11. The first pair of interfaces 121 allows the drainage device 300 to pass through, so that the drainage device 300 can pass through the adhesive tray 11 and the first pair of interfaces 121 from the first bag body 1. The second bag body 2 is provided with a second docking part 21, which is connected and cooperates with the first docking part 12 to connect the first pair of interfaces 121 and the second pair of interfaces 211 of the second docking part 21, so that the drainage device 300 can be inserted into the second bag body 2 through the second pair of interfaces 211.
[0045] Furthermore, the second bag body 2 is also provided with a sealing opening 22, which is used for part of the drainage device 300 to pass through, so that the drainage device 300 can pass through the second bag body 2, and the second bag body 2 can form a seal at the sealing opening 22, thereby forming a sealed structure between the second bag body 2 and the drainage device 300, which helps to provide a relatively closed environment for the patient 200's affected area.
[0046] Combination Figure 4 and Figure 6As shown, the drainage device 300 can extend from the patient's 200's affected area by sequentially passing through the adhesive tray 11, the first pair of interfaces 121, the second pair of interfaces 211, and the sealing port 22, and then extending into the second bag body 2. This allows the drainage device 300 to remain on the patient's 200, and the exudate 400 from the affected area can be collected through the first bag body 1, improving the accuracy of the collected exudate 400. In other words, the exudate collection bag 100 in this application can be adapted to various drainage devices 300, such as local single drainage tubes, local multiple drainage tubes, irregularly shaped drainage tubes, and drainage tubes of various diameters.
[0047] It should be noted that the adhesive tray 11 allows the drainage device 300 to pass through, and the first bag 1 is attached to the affected area of the patient 200 through the adhesive tray 11, which can avoid the drainage device 300. Furthermore, the exudate 400 generated at the affected area can enter the first bag 1 through the adhesive tray 11, and the exudate 400 is collected through the first bag 1.
[0048] Furthermore, the first bag 1 and the second bag 2 are connected and cooperated through the first docking part 12 and the second docking part 21. That is to say, the first bag 1 and the second bag 2 are detachably connected, so that the affected area can be observed through the first pair of interfaces 121 and the second pair of interfaces 211, and the affected area can be treated (such as dressing, disinfection, debridement, etc.).
[0049] In this application, the exudate collection bag 100 includes a first bag body 1 and a second bag body 2 connected together. The first bag body 1 is attached to the skin of the patient 200 at the affected area via an adhesive tray 11, so that the exudate 400 at the affected area can be collected in the first bag body 1. The drainage device 300 can pass through the first bag body 1 and extend into the second bag body 2 and extend out from the sealing opening 22 of the second bag body 2. The sealing opening 22 can form a seal between the second bag body 2 and the drainage device 300, which can provide a closed environment for the affected area while leading the drainage device 300 out from the exudate collection bag 100. Thus, the drainage device 300 can be retained and the exudate 400 can be collected through the first bag body 1. This achieves quantitative collection of perivascular exudate while retaining the drainage device 300 and providing a relatively closed environment for the affected area, which is convenient for the care of the patient 200's affected area.
[0050] In some embodiments of this application, the seepage collection bag 100 is provided with a sealing element 3, which is disposed on at least one of the first docking portion 12 and the second docking portion 21, and the sealing element 3 is used to form a seal between the first docking portion 12 and the second docking portion 21 to improve the sealing performance between the first bag body 1 and the second bag body 2.
[0051] It is understandable that the seal 3 may be provided only on the first mating portion 12, or only on the second mating portion 21. The seal 3 may also be divided into two parts, respectively provided on the first mating portion 12 and the second mating portion 21. (Refer to...) Figure 3 As shown, the sealing element 3 is disposed on the second mating part 21 and is located on some surfaces of the second mating part 21 that are in relative cooperation with the first mating part 12.
[0052] Furthermore, the sealing element 3 can be constructed as a sealing ring, which can avoid the drainage device 300, allowing the drainage device 300 to pass through the sealing ring. When the first mating portion 12 and the second mating portion 21 are connected and engaged, the sealing ring can be sandwiched between the first mating portion 12 and the second mating portion 21 to form a seal between the first mating portion 12 and the second mating portion 21. The sealing ring can be constructed as a silicone element, and the shape of the sealing ring is adapted to the first mating portion 12 or the second mating portion 21.
[0053] like Figure 1 As shown, in some embodiments of this application, the first docking portion 12 is constructed as a first annular seat, which defines a first pair of interfaces 121, and the second docking portion 21 is constructed as a second annular seat, which defines a second pair of interfaces 211. The first annular seat and the second annular seat are engaged, and a connecting strap 4 connects the first annular seat and the second annular seat, thereby connecting the first bag body 1 and the second bag body 2.
[0054] Understandably, when the exudate collection bag 100 is not used with the patient 200, the first bag body 1 and the second bag body 2 are connected only by the connecting strap 4. When the exudate collection bag 100 needs to be applied to the affected area of the patient 200, the first docking part 12 and the second docking part 21 are connected to connect the first bag body 1 and the second bag body 2, and a seal is formed at the connection between the first bag body 1 and the second bag body 2, so that the drainage device 300 passes through the first bag body 1 and the second bag body 2 in sequence and then extends out.
[0055] It should be noted that if one of the first bag body 1 and the second bag body 2 needs to be replaced, the first bag body 1 and the second bag body 2 can be separated by cutting the connecting strap 4, and the first bag body 1 or the second bag body 2 can be replaced as needed. Taking the replacement of the second bag body 2 as an example, when the second bag body 2 needs to be replaced, the first docking part 12 and the second docking part 21 can be separated after cutting the connecting strap 4, and the second docking part 21 of the second bag body 2 to be replaced can be connected and fitted with the first docking part 12 to realize the replacement of the second bag body 2. In particular, when the bag body (such as the first bag body 1 and the second bag body 2 mentioned above) is damaged or the seal fails, the bag body can be replaced to ensure the sealing effect of the seepage collection bag 100.
[0056] In some embodiments of this application, the second bag 2 is provided with a drawstring 23, which is located near the sealing opening 22. The drawstring 23 is used to tie the second bag 2 and the drainage tube 301 of the drainage device 300 tightly together to form a seal between the second bag 2 and the drainage tube 301, providing a relatively closed environment for the affected area.
[0057] The drawstring 23 is removably installed in the second bag body 2 near the sealing opening 22. When the drainage device 300 passes through the sealing opening 22, the second bag body 2 and the drainage tube 301 can be tied together by pulling the drawstring 23 to achieve a seal between the second bag body 2 and the drainage tube 301.
[0058] In some embodiments of this application, the second bag body 2 is provided with an adhesive strip 24, which is located near the sealing opening 22. The adhesive strip 24 can be attached to the drainage device 300 to form a seal between the sealing opening 22 of the second bag body 2 and the drainage tube 301 of the drainage device 300, providing a relatively closed environment for the affected area.
[0059] The adhesive strip 24 is positioned in the second bag body 2 near the sealing opening 22. When the drainage device 300 passes through the sealing opening 22, it can be attached to the drainage tube 301 through the adhesive strip 24 to fix one end of the second bag body 2 forming the sealing opening 22 to the drainage tube 301, thus forming a seal between the sealing opening 22 of the second bag body 2 and the drainage tube 301.
[0060] The second bag body 2 may contain only one of a drawstring 23 and an adhesive strip 24, or both. The drawstring 23 or adhesive strip 24 is positioned within the second bag body 2 near the sealing opening 22 to facilitate a seal between the second bag body 2 and the drainage tube 301 at that location. It should be noted that the specific placement and arrangement of the drawstring 23 and adhesive strip 24 within the second bag body 2 are not specifically limited, as long as a seal between the second bag body 2 and the drainage tube 301 is achieved using the drawstring 23 and adhesive strip 24.
[0061] In some embodiments of this application, the second bag 2 is constructed as a long strip, and the first pair of interfaces 121 and sealing openings 22 are respectively disposed at both ends of the second bag 2 in the length direction. This sets the sealing position of the second bag 2 and the drainage device 300 away from the docking and communication position of the second bag 2 and the first bag 1, increasing the distance between the sealing position and the seepage position. The second bag 2 can play a certain restraining effect on the drainage device 300, thereby reducing the amount of seepage caused by the shaking of the drainage device 300.
[0062] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this application, the first bag 1 is provided with a drainage section 13, which is used to drain the exudate 400 collected in the first bag 1, thereby emptying the first bag 1 and collecting the exudate 400 again through the first bag 1.
[0063] Understandably, the first bag 1 can be used to collect and store exudate 400, and the storage capacity of the first bag 1 for exudate 400 is limited (e.g., 200ml, 300ml, etc.). Therefore, the exudate 400 collected in the first bag 1 can be selectively discharged according to usage needs. For example, when a certain amount of exudate 400 has been collected and stored in the first bag 1 (the amount of exudate 400 stored in the first bag 1 has reached the preset range), the exudate 400 in the first bag 1 can be discharged. After the exudate 400 in the first bag 1 is discharged, the exudate 400 can be collected again through the first bag 1. When the first bag 1 has collected exudate for a preset time (e.g., 12 hours, 24 hours), the exudate 400 in the first bag 1 can be discharged, thereby enabling the periodic collection of exudate 400 generated by patient 200 to facilitate the assessment of patient 200's condition.
[0064] It should be noted that when the exudate collection bag 100 is applied to the affected area of the patient 200, the drainage section 13 is located below the adhesive tray 11, thereby allowing the exudate 400 to be drained from the bottom of the first bag body 1, ensuring the effective drainage of the exudate 400. The adhesive tray 11 is arranged in the upper region of the first bag body 1, thus creating a space for storing the exudate 400 in the area below the adhesive tray 11 within the first bag body 1, and preventing backflow of the exudate 400.
[0065] like Figure 1 As shown in a further embodiment of this application, the drainage section 13 includes a drainage pipe 131 and a plug 132. One end of the drainage pipe 131 communicates with the interior of the first bag 1, and the other end of the drainage pipe 131 is used to cooperate with the plug 132. The plug 132 can seal the other end of the drainage pipe 131, allowing the exudate 400 to be collected inside the first bag 1. When it is necessary to drain the exudate 400 from the first bag 1, the plug 132 can be removed from the drainage pipe 131, allowing the exudate 400 in the first bag 1 to be discharged outward from the drainage pipe 131.
[0066] When a quantitative drainage is required, the exudate 400 in the first bag 1 can be directly poured out and measured by pulling out the plug 132. Alternatively, another drainage bag can be connected to the end of the drain pipe 131 that is matched with the plug 132, and the exudate 400 can be continuously collected and measured through the drainage bag.
[0067] like Figure 5 As shown, in some embodiments of this application, the drain section 13 is configured as a three-way valve 133.
[0068] The first port 1331 of the tee 133 is connected to the interior of the first bag body 1, so that the exudate 400 in the first bag body 1 can flow into the tee 133 through the first port 1331. The second port 1332 of the tee 133 is connected to the drainage tube 301, so that the liquid in the drainage tube 301 can flow into the tee 133 through the second port 1332. The exudate 400 flowing into the tee 133 can be discharged through the third port 1333.
[0069] In a further embodiment of this application, the leachate collection bag 100 further includes a third bag body, which is connected to the third interface 1333 and is used to collect leachate 400.
[0070] The third port 1333 of the three-way valve 133 is connected and cooperates with the third bag (not shown), so that the exudate 400 generated by the patient 200 and the liquid drawn out by the drainage tube 301 can be collected through the third bag.
[0071] In a further embodiment of this application, the third bag may be marked with graduations to facilitate the acquisition of fluid volume parameters by nursing staff. This reduces the difficulty of drainage measurement, allowing nursing staff to directly obtain the amount of fluid drained by the patient 200 by observing the third bag, achieving simultaneous measurement of the exudate 400 from the affected area and the drainage fluid from the drainage tube 301, and making the measurement more accurate and intuitive.
[0072] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the first bag 1 is marked with a scale line 14. The scale line 14 is used to mark the volume of the exudate 400 collected in the first bag 1, and the scale line 14 allows the caregiver to intuitively obtain the amount of exudate 400 in the first bag 1.
[0073] Reference Figure 7 As shown, the first bag 1 is used to collect the exudate 400 generated by the patient 200 at the affected area. When it is necessary to measure the drainage of the exudate 400 generated by the patient 200, the nursing staff can obtain the amount of exudate 400 collected in the first bag 1 by observing the scale line 14 on the first bag 1.
[0074] in, Figure 6 and Figure 7The affected area of patient 200 shown in the figure is located in the chest cavity. In the chest cavity, closed chest drainage or a drainage device 300 with a negative pressure device (not shown in the figure) is usually required for drainage. Therefore, when the exudate collection bag 100 is attached to patient 200, it is necessary to ensure that the position of the drainage device 300 does not change. That is, the position of the drainage device 300 drawn from the patient 200's body is fixed, and the position of the drainage device 300 does not change during the process of attaching the exudate collection bag 100 to the patient 200's skin.
[0075] like Figure 3 As shown, in some embodiments of this application, the adhesive tray 11 includes an adhesive base 111 and a cutting tray 112. The adhesive base 111 has an adhesive surface for adhering to the skin of the patient 200 to fix the first bag 1 to the patient 200. A through hole is formed in the middle of the adhesive base 111. The cutting tray 112 is disposed in the through hole and has a spirally extending cutting line. The cutting tray 112 can be cut along the cutting line to adjust the opening size at the adhesive tray 11.
[0076] It should be noted that the cutting method of the cutting tray 112 is not limited to this. The cutting tray 112 can also be freely cut according to the arrangement requirements of the drainage device 300. For example, when multiple adjacent drainage devices 300 need to pass through the same adhesive tray 11, the shape of the cutting tray 112 can be adapted to the position of the drainage device 300 leading out of the patient 200, so that the shape and size of the opening formed on the cutting tray 112 can match the multiple drainage devices 300. When the cutting tray 112 is used for the passage of irregularly shaped drainage tubes, the cutting tray 112 can be adapted to the cross-sectional size and shape of the irregularly shaped drainage tubes to meet the arrangement requirements of the irregularly shaped drainage tubes passing through the cutting tray 112.
[0077] Reference Figure 3 The adhesive base 111 is used to adhere to the patient 200, and the through hole of the adhesive base 111 is used for the drainage device 300 to pass through.
[0078] The cutting disc 112 is disposed in the through hole of the adhesive base 111. The cutting disc 112 can block the through hole. By cutting the cutting disc 112, the blocking area of the cutting disc 112 on the through hole can be adjusted, thereby forming an opening at the cutting disc 112 that is suitable for the drainage device 300 to pass through. While ensuring the blocking effect at the through hole, the compatibility between the adhesive disc 11 and the drainage device 300 is improved.
[0079] Reference Figure 3 As shown, when it is necessary to increase the size of the opening formed by the cutting disc 112, the cutting range can be gradually increased from the center of the cutting disc 112 outwards to gradually increase the size of the opening formed at the cutting disc 112.
[0080] Reference Figures 1-7 Describes the usage process of the seepage collection bag 100 according to an embodiment of this application:
[0081] When it is necessary to place the exudate collection bag 100 on the affected area of the patient 200, the cutting plate 112 at the adhesive plate 11 is first cut to form an opening suitable for the drainage device 300 to pass through. Then, the drainage device 300 is passed through the adhesive plate 11 and the first interface 121 in sequence, so that the drainage device 300 passes out from the first bag body 1. At this time, the adhesive plate 11 can be attached to the skin of the patient 200 to attach the first bag body 1 to the affected area and collect the exudate 400 through the first bag body 1.
[0082] Furthermore, the drainage device 300 is inserted into the second bag body 2 through the second pair of interfaces 211, and the drainage device 300 is led out from the sealing opening 22 of the second bag body 2. At this time, the first docking part 12 and the second docking part 21 can be docked and matched, and then a seal is formed at the sealing opening 22 by a sealing structure (such as: drawstring 23, adhesive strip 24).
[0083] Understandably, when the bags in the exudate collection bag 100 (e.g., the first bag 1, the second bag 2, and the third bag) need to be replaced, the bags that need to be replaced can be replaced individually, thereby reducing the cost of medical consumables.
[0084] The seepage collection bag 100 according to the embodiments of this application has at least the following advantages compared with the prior art:
[0085] (1) The exudate collection bag 100 can be used with the patient 200 while retaining the drainage device 300 completely, and can collect the exudate 400 generated by the patient 200 at the affected site, which can meet the usage requirements of the drainage device 300 for closed chest drainage and drainage with negative pressure device. At the same time, the exudate collection bag 100 can be adapted to the drainage device 300 with local single drainage tube, local multiple drainage tube, special-shaped drainage tube, and drainage tubes of various sizes and diameters.
[0086] (2) The first bag 1 and the second bag 2 are connected and fitted together through the first docking part 12 and the second docking part 21. That is to say, the first bag 1 and the second bag 2 are detachably connected, so that the affected area can be observed through the first pair of interfaces 121 and the second pair of interfaces 211, and the affected area can be easily treated (such as dressing change, disinfection, debridement, etc.). At the same time, when it is necessary to replace the bag, the corresponding bag can be replaced according to the replacement needs, saving medical consumable costs.
[0087] (3) The outlet position of the drainage device 300 is limited to the area of the first pair of interfaces 121 and the second pair of interfaces 211, and the drainage device 300 and the second bag body 2 are sealed together at the sealing port 22, so that the drainage device 300 can be constrained and positioned by the seepage collection bag 100.
[0088] (4) One end of the second bag 2 forming the sealed opening 22 can be fixed to the drainage tube 301 by the drawstring 23 and the adhesive strip 24, which can reduce the damage to the second bag 2 caused by the stretching and deformation of the drainage device 300, help keep the affected area clean and facilitate care.
