Description
Technical Field
[0001] The utility model relates to the technical field of postoperative wound care, in particular to a postoperative wound dressing system. Background Art
[0002] After surgical operations, especially when drainage tubes are required, wound management becomes particularly important. Effective wound management aims to promote early healing while preventing contamination by external microorganisms and the formation of fluid and gas accumulation. However, the monolithic wound dressings currently used in clinical practice cannot fully meet these needs. In particular, when it comes to the fixation and management of drainage tubes, existing dressing designs have obvious limitations. On the one hand, monolithic dressings need to be cut out with holes for the drainage tube to pass through before use. This process is not only time-consuming and inefficient, but may also affect the coverage of the dressing or the passage of the drainage tube due to improper cutting; on the other hand, existing dressings lack an effective mechanism for secondary fixation of the drainage tube, and clinical nursing staff often need to use additional medical fixation patches or tapes for fixation, which not only increases the workload, but may also affect the drainage effect due to improper fixation.
[0003] In response to these problems, it is necessary to develop a new dressing design that can provide better wound coverage while allowing the drainage tube to pass through and fix smoothly. The new dressing should be able to adapt to wounds of different sizes and shapes, ensure the stable fixation of the drainage tube, maximize the absorption of blood and exudate around the wound, and prevent the occurrence of unplanned extubation. Such a dressing design can not only improve the efficiency of clinical care, but also promote early wound healing and provide patients with a more comfortable and safe recovery environment. Utility Model Content
[0004] The purpose of the utility model is to solve the above-mentioned problems and provide a postoperative wound dressing system, in which the drainage tube is supported and fixed by a fixing member so that the drainage tube can remain upright without being folded. At the same time, the dressing with preset through holes makes it simple to operate during assembly and use without the need for additional cutting.
[0005] The utility model achieves its invention purpose through the following technical solutions:
[0006] A postoperative wound dressing system, wherein the fixing part is a movable fixing part or a detachable part, which is fixed on the outer surface of a drainage tube, and the fixing part wraps a supporting part to support the drainage tube; the postoperative dressing system is composed of a drainage tube with a self-fixing part, an absorption layer and a dressing layer, and is used to absorb exudate exudated from the wound and protect the wound.
[0007] Furthermore, the movable fixing part is composed of a vertical supporting tube and a horizontal anti-slipping part, a hollow pipe with the same diameter is located between the supporting tube and the anti-slipping part, and the outer diameter of the anti-slipping part is 0.5-2 times the outer diameter of the supporting tube.
[0008] Furthermore, the lower surface of the anti-slip component has a plurality of drainage grooves, the drainage grooves penetrate the inner diameter and the outer diameter of the anti-slip component, and the drainage grooves are formed by being recessed inwardly along the lower surface of the anti-slip component.
[0009] Furthermore, the postoperative wound dressing system also wraps an absorption layer placed close to the side surface of the anti-slip component, wherein the absorption layer is a hollow annular structure, and the inner diameter of the annular structure is the same as the outer diameter of the anti-slip component.
[0010] Furthermore, the postoperative wound dressing system also wraps a dressing layer, and a preset hole with a diameter the same as the outer diameter of the drainage tube is provided in the center of the dressing layer. The preset hole passes through the drainage tube and is placed above the absorption layer and the anti-slip component, and is fixed to the skin by the adhesive on the lower surface of the dressing layer.

DETAILED DESCRIPTION
[0031] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work. The content of the utility model is further explained below in conjunction with the drawings.
[0032] In order to solve the nursing problem of drainage tubes left after surgery, it is required that the drainage tubes should be fixed vertically on the skin surface without bending, so as to ensure smooth drainage; secondly, in the wounds that need drainage after surgery, there will often be exudate seeping between the drainage tubes and the wounds, and the absorption of the exudate must be considered to prevent the exudate from directly soaking the dressings, causing the dressings to fail quickly. This situation is very bad for nursing, because the drainage tubes are left in the body, and it is very inconvenient to change the dressings alone without removing the tubes, and it may also cause secondary damage or failure of the drainage tubes. Example 1
[0033] As shown in the figure, Figure 2 , Figure 3 , Figure 4 As shown, there is a movable fixing member 200 on the outer surface of the drainage tube 100, which is achieved by passing the fixing member 200 through the drainage tube 100 and sleeved on the outer surface of the drainage tube 100. The fixing member 200 is composed of a vertical hollow support tube 210 and an anti-slip member 220 horizontally arranged perpendicular to the fixing member 200. The anti-slip member 220 is a hollow cylinder with a thickness of 1-10 mm. The outer diameter of the anti-slip member 200 is greater than the outer diameter of the support tube 210, and the outer diameter of the anti-slip member 200 is 0.5-2 times the outer diameter of the support tube 210. The inner diameters of the anti-slip member 200 and the support tube 210 are the same.
[0034] The support tube 210 is a hollow tubular structure. When the drainage tube 100 is placed therein, it provides a supporting force so that the drainage tube 100 can remain vertical and not bend under the action of the support tube 210, and can drain smoothly. The drainage tube 100 is usually easy to bend at the wound surface, resulting in poor drainage. By propping it up for a distance, the drainage tube 100 is filled with drainage fluid, and then the drainage tube 100 is placed in a drainage bottle or drainage bag, so that drainage can be smoothly achieved.
[0035] There are several drainage grooves 230 on the lower surface of the anti-slip component 200 (the side in contact with the wound). The drainage grooves 230 penetrate the inner diameter and outer diameter of the anti-slip component 220 to form a drainage groove 230 that is recessed inward along the lower surface of the anti-slip component 200.
[0036] In the dressing system composed of the drainage tube with a fixing part, an absorption layer 300 is also included. The cross section of the absorption layer 300 is a hollow ring. The inner diameter of the ring is the same as the outer diameter of the anti-slip part 220. When in use, the absorption layer 300 is placed on the side surface of the anti-slip part 220. At this time, the inner side of the absorption layer 300 is in direct contact with the outlet of the drainage groove 230. The thickness of the absorption layer 300 is 1-10mm. The exudate flowing out of the wound will flow into the absorption layer 300 along the drainage groove 230 and be absorbed by the absorption layer 300, thereby avoiding the exudate from directly infiltrating the dressing layer. The absorption layer 300 is made of a material with high absorption performance, such as polyvinyl alcohol material.
[0037] Finally, in the dressing system, the dressing layer 400 is also wrapped. The dressing layer 400 is a conventional wound protection dressing, and its thickness is usually thin. For example, the thickness of a hydrogel dressing is usually 1-5 mm, the thickness of a foam dressing is usually 1-10 mm, and the thickness of an alginate dressing is usually within a few millimeters. In this embodiment, the dressing layer 400 is a rounded rectangular dressing, and a preset hole 410 is preset at the center of the dressing layer 400. The preset hole 410 has been opened in advance and is connected to the body of the dressing layer 400 through multiple points. When in use, it only needs to be removed with a little force without cutting. The diameter of the preset hole 410 is the same as the outer diameter of the support tube 210. When in use, the preset hole 410 is passed through the outer surfaces of the drainage tube 100 and the support tube 210 in sequence and placed above the absorption layer 300. After the drainage tube 100 is placed, the position of the fixing part 200 is adjusted so that its lower surface is placed around the wound. At this time, the absorption layer 300 is also located around the wound, and then it is adhered and fixed to the skin surface through the upper dressing layer 400 (there is an adhesive on the lower surface of the dressing layer 400, and the adhesive range at least covers the area of the dressing layer 400 outside the absorption layer 300). Example 2
[0038] On the basis of Example 1, the universality of the fixing member 200 is considered so that it can be suitable for drainage tubes of different sizes and shapes, such as Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the fixing member 200 is optimized to form a detachable fixing member 500. The detachable fixing member 500 is detachably fixed on the outer surface of the drainage tube 100, and the detachable fixing member 500 is composed of a first part 510 and a second part 520, and the first part 510 and the second part 520 are composed of a first vertical plate 540 and a second vertical plate 550 and a connecting curved surface 560 connecting the first vertical plate 540 and the second vertical plate 550, wherein the first vertical plate 540 and the second vertical plate 550 are arranged in parallel.
[0039] On the side surface (on the right surface in the figure) of the free end of the first vertical plate 540 and the second vertical plate 550 of the first part 510, there is a slot 511 formed by an inward depression, and the depth of the slot 511 is 1 / 3-2 / 3 of the width of the first vertical plate 540. On the side surface (on the left surface in the figure) of the free end of the first vertical plate 540 and the second vertical plate 550 of the second part 520, there is an insertion part 521 of the same shape and size as the slot 511, and the insertion part 521 is fixed by inserting into the slot 511, and the fixed position can be adjusted. The first part 510 and the second part 520 are closely attached to the connecting curved surface 560 and are provided with a supporting sponge 530 inwardly, and the supporting sponge 530 plays a role of auxiliary support and fixation. When in use, the drainage tube 100 is wrapped inside by the first part 510 and the second part 520, and the drainage tube 100 can be supported and fixed by adjusting it to a suitable size. In this process, the sponge plays an auxiliary role, and the drainage tube 100 is fixed by the cooperation of the slot 511 and the insertion part 521.
[0040] In addition, an adhesive layer 540 is fixed above the supporting sponge 530 . When the drainage tube 100 is buckled into the first part 510 and the second part 520 , the adhesive layer 540 is adhered to the outer surface of the drainage tube 100 , thereby achieving double fixation.
[0041] The structure with the adhesive layer 540 is particularly suitable for the first dressing system composed of the structural assembly of Example 2. Specifically, after the drainage tube 100 is retained in the body, the first part 510 and the second part 520 are fastened to the outer surface of the drainage tube 100 through the slot 511 and the insertion part 521. After adjusting to a suitable position, the adhesive layer 540 is adhered to the outer surface of the drainage tube 100. At this time, the adhesive layer 540 and the detachable fixing part 500 provide sufficient height support for the drainage tube 100. In addition, the dressing layer and the absorption layer are omitted (the support sponge 530 also serves as the absorption layer). This dressing system is suitable for wounds with little exudate.
[0042] In addition, there is another conventional assembly method, such as Figure 7 As shown, the outer surface of the drainage tube 100 is sequentially passed through the superimposed absorption layer 300 and the dressing layer 400, where the inner diameters of the absorption layer 300 and the dressing layer 400 are the same as the outer diameter of the drainage tube 100. Finally, the detachable fixing member 500 is fixed on the top of the dressing layer 400 and next to the dressing layer 400. At this time, the support sponge 530 in the detachable fixing member 500 only plays the role of auxiliary support and fixation of the drainage tube 100.
[0043] The detachable fixing part 500 in this embodiment is applicable to circular drainage tubes or elliptical drainage tubes, and can also be applicable to drainage tubes of different sizes. It has a wider range of applications. In addition, it is easier to replace the dressing without removing the drainage tube 100. The detachable fixing part 500 is easier to remove, and a lateral force is applied during removal instead of a longitudinal force. Comparatively, it is not easy to remove the drainage tube 100 from the body.
