Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a combined postoperative abdominal binder that combines drainage management and external drug application functions. Background Technology

[0002] Following abdominal surgery, patients often require both wound drainage and topical medication. Drainage tubes are used to remove postoperative abdominal fluid, while topical medications (such as Glauber's salt poultices) are used to reduce swelling, fight infection, and promote wound healing. Currently, clinical practice typically uses separate drainage tube fixation devices and individual abdominal binders or medication bags to perform these two functions, which is cumbersome and ineffective.

[0003] Existing technologies already include several solutions that combine abdominal binders with drainage tube fixation functions. For example, Chinese patent CN221787029U discloses an abdominal binder for use after gynecological abdominal surgery to facilitate drainage of accumulated fluid. This binder uses a perforation hole in the binder for the drainage tube to pass through, and a hook to secure the drainage tube. However, the perforation hole in this design is fixed in position, making it impossible to flexibly adjust to different patients' wound locations. Furthermore, it lacks flexible clamping protection for the drainage tube, which may still be compressed or pulled due to patient movement. In addition, this abdominal binder does not have a medicated dressing function.

[0004] On the other hand, Chinese patent CN209361635U discloses a modular detachable Glauber's salt abdominal binder, which is formed by multiple detachably connected outer bags, and an inner bag of Glauber's salt can be placed inside the outer bags for external application of the medicine. However, this solution only solves the problem of external application of the medicine and does not address the management and fixation of the drainage tube. Furthermore, the outer bags are simply connected by buckles, lacking planning and limiting design for the passage path of the drainage tube.

[0005] Therefore, existing technologies lack a postoperative abdominal binder that can simultaneously provide flexible fixation and zonal medication application, and can be flexibly configured according to individual patient conditions. To address these issues, this invention proposes a combined postoperative abdominal binder that integrates drainage management and medication application functions. Summary of the Invention

[0006] The purpose of this invention is to provide a combined postoperative abdominal binder that combines drainage management and external drug application functions, solving the problems in existing postoperative abdominal binders that cannot simultaneously achieve flexible fixation of drainage tubes and external drug application functions, and that are difficult to configure flexibly according to individual patient conditions.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a combined postoperative abdominal binder that combines drainage management and external drug application functions, including a central abdominal binder and multiple first side abdominal binders that are combined and spliced ​​with the central abdominal binder; The central abdominal band has a medicine application groove in the middle and multiple first drainage tube limiting grooves on its side. A second drainage tube limiting groove corresponding to the first drainage tube limiting groove is provided on the side of the first side abdominal band. A first splicing hook and loop fastener is provided on the first side abdominal band, and a fourth hook and loop fastener adapted to the first splicing hook and loop fastener is provided on the middle abdominal band. After the second drainage tube limiting groove is aligned with the first drainage tube limiting groove, it is used to limit the drainage tube. A first limiting airbag is provided in the first drainage tube limiting groove, and a second limiting airbag is provided in the second drainage tube limiting groove. After the first limiting airbag and the second limiting airbag are inflated, they clamp and position the drainage tube.

[0008] Furthermore, first Velcro straps are provided at both ends of the central abdominal band for wrapping around the abdomen and connecting at the waist; second Velcro straps are provided at both ends of the first side abdominal band for wrapping around the abdomen and connecting at the waist.

[0009] Furthermore, a first inflation tube connecting each of the first limiting airbags is embedded in the middle abdominal band, and an inflation valve is provided at the end of the first inflation tube.

[0010] Furthermore, a sealing airbag for the application groove is provided at the bottom of the application groove to fit the skin, and the sealing airbag is connected to a first inflation tube.

[0011] Furthermore, a first side abdominal band and a second side abdominal band are symmetrically arranged on both sides of the central abdominal band; wherein the first side abdominal band and the second side abdominal band have the same structure.

[0012] Furthermore, a third drainage tube limiting groove corresponding to the first drainage tube limiting groove is provided on the side of the second side abdominal binder; third Velcro straps are respectively provided at both ends of the second side abdominal binder for wrapping around the abdomen and connecting at the waist. A second Velcro fastener is provided on the second side abdominal band, and a fourth Velcro fastener adapted to the second Velcro fastener is provided on the middle abdominal band. After the third drainage tube limiting groove is aligned with the first drainage tube limiting groove, it is used to limit the drainage tube.

[0013] Furthermore, multiple second drainage tube limiting grooves are evenly spaced on the side of the first side abdominal band. A first splicing Velcro is provided on the non-attached surface of the first side abdominal band and between two adjacent second drainage tube limiting grooves; The second limiting airbags in the second drainage tube limiting groove are inflated through the second inflation tube. An airbag inflation valve is provided at the end of the second inflation tube. The second inflation tube is embedded in the first side abdominal band.

[0014] Furthermore, the middle part of the fourth hook and loop fastener is connected to the middle abdominal band, and its two ends are respectively provided with hook or loop surfaces for connecting the first splicing hook and loop fastener.

[0015] Furthermore, an arc-shaped piece is provided in the second drainage tube limiting groove, and the top of the arc-shaped piece extends above the non-attached surface of the first side abdominal band.

[0016] Furthermore, an absorbent material layer is provided on the inner wall of the application trough.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) Flexible clamping and positioning of drainage tube: By setting an inflatable airbag in the limiting groove of the drainage tube, the drainage tube can be flexibly clamped and positioned after inflation. Compared with the existing technology of using tape or rigid buckle to fix, the present invention can not only firmly fix the drainage tube, but also avoid excessive pressure on the drainage tube, which would lead to poor drainage, and at the same time avoid the discomfort caused to the patient's skin by tape.

[0018] (2) Modular splicing structure, flexible fit: The central abdominal band and the side abdominal bands can be detached and spliced ​​together by Velcro. The number and splicing position of the side abdominal bands can be flexibly selected according to the patient's body shape and wound location. The drainage tube limiting groove is adjusted synchronously with the side abdominal bands to ensure that the drainage tube always passes out of the abdominal band through the shortest path, reducing the risk of the drainage tube bending outside the body.

[0019] (3) Integration of drainage management and external drug application functions: The middle abdominal belt integrates both the drug application groove and the drainage tube limiting groove, so that the normal passage and fixation of the drainage tube can be achieved while realizing external drug application treatment, thus solving the problem that the two functions cannot be taken into account in the existing technology.

[0020] (4) Good sealing of the dressing tray: The bottom of the dressing tray is equipped with a sealing airbag. After inflation, the edge of the dressing tray can be closely attached to the patient's skin to prevent the medicine from leaking and contaminating clothing and sheets. At the same time, the absorbent material layer can absorb excess exudate and keep the area around the wound dry.

[0021] (5) Easy to operate and high patient comfort: The airbag inflation operation is simple and can be uniformly inflated through the inflation valve; the Velcro splicing method makes it easy for medical staff to quickly assemble and disassemble, and also makes it easy to clean, disinfect or replace individual parts.

[0024] Example 1 This embodiment discloses a combined postoperative abdominal binder that combines drainage management and external drug application functions, including a central abdominal binder 1 and multiple first side abdominal binders 2 that are combined and spliced ​​with the central abdominal binder 1.

[0025] The central abdominal band 1 is a flexible band structure made of medical cotton or elastic fabric. Its width can be selected according to the size of the patient's abdomen, generally preferably 8-15cm. A medication application groove 13 is provided in the middle of the central abdominal band 1. The medication application groove 13 is an inwardly recessed bag-like structure used to hold external medication packs (such as Glauber's salt packs, traditional Chinese medicine plasters, etc.). The depth of the medication application groove 13 is preferably 1-3cm, and its shape can be circular, elliptical, or rectangular, depending on the shape of the external medication. An absorbent material layer is provided on the inner wall of the medication application groove 13. The absorbent material layer is preferably medical absorbent cotton or non-woven fabric, used to absorb wound exudate or medication seepage from the medication pack, keeping the area around the wound dry.

[0026] A sealing airbag 131 is provided at the bottom edge of the application tray 13. The sealing airbag 131 is continuously or segmented along the periphery of the application tray 13. The sealing airbag 131 is connected to an external inflation device through a first inflation tube 14. When the sealing airbag 131 is inflated, it expands towards the patient's skin, causing the edge of the application tray 13 to fit tightly against the patient's abdominal skin, forming a sealed structure and preventing the medicine from seeping out from the edge of the application tray 13 and staining clothing and sheets.

[0027] The two ends of the central abdominal band 1 are respectively provided with a first Velcro 11 (specifically, the hook side or the rough side of the Velcro), which is used to connect and fix the central abdominal band 1 around the patient's abdomen at the waist.

[0028] Multiple first drainage tube limiting grooves 12 are also provided on the side of the central abdominal band 1. The first drainage tube limiting groove 12 is a slotted structure that runs through the thickness direction of the central abdominal band 1, and its width is slightly larger than the outer diameter of a conventional drainage tube so that the drainage tube can pass through freely. The first drainage tube limiting grooves 12 are evenly distributed along the length direction of the central abdominal band 1, and the distance between two adjacent first drainage tube limiting grooves 12 is preferably 2 to 5 cm.

[0029] A first limiting airbag 121 is provided within the first drainage tube limiting groove 12. The first limiting airbag 121 is arranged in a ring or C-shape on the inner wall of the first drainage tube limiting groove 12. Each first limiting airbag 121 is interconnected through a first inflation tube 14 embedded inside the central abdominal band 1. An inflation valve is provided at the end of the first inflation tube 14, which can be a one-way valve or a valve with a pressure relief function. When air is inflated into the first inflation tube 14 through the inflation valve, each first limiting airbag 121 expands synchronously, forming a ring-shaped wrapping clamp on the drainage tube passing through the first drainage tube limiting groove 12.

[0030] refer to Figure 1 , Figure 7 , Figure 8 The first side abdominal band 2 is a flexible band-like structure similar in structure to the central abdominal band 1, and its length can be selected as needed. Second Velcro closures 21 are provided at both ends of the first side abdominal band 2 for securing it around the patient's abdomen at the waist. A second drainage tube limiting groove 22, corresponding to the first drainage tube limiting groove 12, is provided on the side of the first side abdominal band 2. The structure of the second drainage tube limiting groove 22 is the same as that of the first drainage tube limiting groove 12, and a second limiting airbag 221 is provided within it.

[0031] A first hook-and-loop fastener 23 is provided on the first side abdominal band 2, and a fourth hook-and-loop fastener 4 adapted to the first hook-and-loop fastener 23 is provided on the middle abdominal band 1. The middle part of the fourth hook-and-loop fastener 4 is fixedly connected to the middle abdominal band 1, and its two ends are respectively provided with hook or loop surfaces for connecting the first hook-and-loop fastener 23. When the first side abdominal band 2 and the middle abdominal band 1 are joined, the second drainage tube limiting groove 22 is aligned with the first drainage tube limiting groove 12, and then the first hook-and-loop fastener 23 and the fourth hook-and-loop fastener 4 are glued together to achieve a fixed connection. The aligned first drainage tube limiting groove 12 and the second drainage tube limiting groove 22 together form a complete drainage tube passage channel, through which the drainage tube exits the abdominal band.

[0032] The second limiting airbags 221 within the second drainage tube limiting groove 22 are inflated via second inflation tubes 222, with an inflation valve 223 located at the end of each inflation tube 222. The second inflation tubes 222 are embedded within the first side abdominal band 2. This independent inflation method allows each second limiting airbag 221 to have its inflation volume individually controlled according to actual needs, achieving differentiated clamping force on different sections of the drainage tube.

[0033] A plurality of second drainage tube limiting grooves 22 are evenly spaced along the sides of the first side abdominal band 2, and the distance between two adjacent second drainage tube limiting grooves 22 is the same as the distance between two adjacent first drainage tube limiting grooves 12 on the central abdominal band 1. A first splicing Velcro closure 23 is provided on the non-attached surface (i.e., the side away from the patient's skin) of the first side abdominal band 2 and between two adjacent second drainage tube limiting grooves 22.

[0034] Preferably, an arc-shaped piece is also provided in the second drainage tube limiting groove 22, with the top of the arc-shaped piece extending above the non-attached surface of the first side abdominal band 2. The arc-shaped piece can serve as a guide structure when the drainage tube passes through, making it easier for medical staff to pass the drainage tube out of the limiting groove. At the same time, the arched structure of the arc-shaped piece can resist the pressure of external pressure on the drainage tube to a certain extent.

[0035] Example 2 Based on Example 1, this embodiment provides a first side abdominal band 2 and a second side abdominal band 3 symmetrically arranged on both sides of the central abdominal band 1, wherein the first side abdominal band 2 and the second side abdominal band 3 have the same structure.

[0036] The second side abdominal band 3 has a third Velcro closure 31 at each end for securing it around the waist after wrapping around the abdomen. The second side abdominal band 3 has a third drainage tube limiting groove 32 on its side, corresponding to the first drainage tube limiting groove 12. The structure of the third drainage tube limiting groove 32 is the same as that of the first drainage tube limiting groove 12 and the second drainage tube limiting groove 22.

[0037] A second hook-and-loop fastener 33 is provided on the second side abdominal band 3, and a fourth hook-and-loop fastener 4 adapted to the second hook-and-loop fastener 33 is provided on the middle abdominal band 1. After the third drainage tube limiting groove 32 is aligned with the first drainage tube limiting groove 12, the second hook-and-loop fastener 33 and the fourth hook-and-loop fastener 4 are glued together to form a drainage tube passage.

[0038] In this embodiment, side abdominal bands can be simultaneously spliced ​​onto both sides of the central abdominal band 1, which is suitable for patients with wounds or drainage tubes on both sides of the abdomen. Medical staff can choose to splice side abdominal bands onto one or both sides of the central abdominal band 1 according to actual needs, flexibly meeting the clinical needs of different patients.

[0039] Example 3 This embodiment provides a method for using the combined postoperative abdominal binder that combines drainage management and external medication functions, including the following steps: Step 1: Assemble the abdominal binder Based on the patient's body size and wound location, select an appropriate number of first side abdominal bands 2 (and / or second side abdominal bands 3). Align the drainage tube limiting grooves on the selected side abdominal bands with the first drainage tube limiting grooves 12 on the central abdominal band 1, and then fix them by attaching the splicing Velcro on the side abdominal bands to the fourth Velcro 4 on the central abdominal band 1 to complete the assembly of the abdominal bands.

[0040] Step Two: Place the medication Place the medicated dressing (such as a Glauber's salt pack) into the dressing tray 13 of the central abdominal bandage 1. If cold or hot compresses are required, an ice pack or heating pad can be placed in the dressing tray 13 before placing the medicated dressing. The absorbent material layer 15 on the inner wall of the dressing tray 13 can absorb exudate and keep the wound dry.

[0041] Step 3: Seal the application tank Inflate the medicine application groove sealing airbag 131 by inflating it through the inflation valve at the end of the first inflation tube 14. This causes the medicine application groove sealing airbag 131 to expand, tightly sealing the edge of the medicine application groove 13 against the patient's abdominal skin to form a seal and prevent leakage of the medicine.

[0042] Step 4: Put on the abdominal binder The assembled abdominal binder is placed on the patient's abdomen, with the dressing groove 13 aligned with the area where the medication needs to be applied, and the first drainage tube limiting groove 12 aligned with the position where the drainage tube exits the wound. The first Velcro 11 at both ends of the central abdominal binder 1 is wrapped around the patient's lower back and then fastened at the waist. Subsequently, the Velcro 21 / 31 at both ends of each side abdominal binder are wrapped around the patient's lower back and then fastened at the waist, completing the initial wearing and fixation of the abdominal binder.

[0043] Step 5: Insert the guide tube The drainage tube, brought out from the patient's wound, is passed through the abdominal binder through the aligned drainage tube limiting groove (formed by the first drainage tube limiting groove 12, the second drainage tube limiting groove 22, and the third drainage tube limiting groove 32). After the drainage tube is passed through, it can be further guided to a collection device such as a drainage bag as needed.

[0044] Step Six: Use an airbag to clamp and secure the drainage tube. Inflation is achieved by inflating the first limiting airbag 121 through the inflation valve at the end of the first inflation tube 14 on the central abdominal band 1, causing the first limiting airbag 121 to expand and clamp and position the drainage tube portion passing through the first drainage tube limiting groove 12. Simultaneously, inflation is achieved by inflating the corresponding second limiting airbag 221 (or the limiting airbag in the third drainage tube limiting groove 32) through the airbag inflation valve 223 at the end of the second inflation tube 222 on each side abdominal band, causing each limiting airbag to expand and clamp and position the corresponding section of the drainage tube.

[0045] The inflation volume of each limiting airbag can be adjusted according to the diameter of the drainage tube and the required clamping force, so as to securely fix the drainage tube without causing excessive pressure on the drainage tube and thus obstructing drainage.

[0046] Step 7: Adjustments during use During use, if it is necessary to replace the external medication pack in the medication packing tray 13, first deflate the sealing airbag 131 of the medication packing tray, remove the old medication pack, put in the new medication pack, and then re-inflate and seal the sealing airbag 131 of the medication packing tray. If it is necessary to adjust the position of the drainage tube or replace the drainage tube, first deflate the corresponding limiting airbag to release the clamp on the drainage tube, complete the adjustment, and then re-inflate and clamp it.

[0047] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
