Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wound care, and in particular to a novel negative pressure drainage tube suitable for wounds with more pus and a dressing system using the drainage tube. Background Art
[0002] As an effective means to promote wound healing, negative pressure drainage technology has been widely used in the treatment of various types of wounds, especially in the treatment of complex or large-area trauma. However, existing negative pressure drainage dressings are mostly produced in standardized specifications, which to a certain extent limits their flexibility in use in special parts, such as curved or irregular areas such as hands. The traditional approach is to manually cut the dressing to fit the shape and size of these special parts, which is not only time-consuming and labor-intensive, but also difficult to achieve a perfect fit for the wound. Sometimes, improper cutting may even affect the efficiency and effectiveness of negative pressure drainage.
[0003] Of course, there are dressings suitable for special parts, but they are still not widely used in clinical practice. The main reason is that the dressing is only suitable for a certain part and is not universal. In addition, due to demand, the mass production quantity is small, which makes the price of this dressing relatively high.
[0004] In addition, the treatment of large wounds often faces the situation where the dressing requirements exceed the coverage of a single dressing, which requires that the dressings can be effectively spliced to form a continuous treatment area. These requirements force us to rethink the design concept of dressings and find a solution that can flexibly adapt to wounds of different shapes and sizes and can easily realize the splicing of multiple dressings.
[0005] Therefore, there is an urgent problem that needs to be solved: how to optimize the design of negative pressure drainage dressings so that they can meet the needs of individualized treatment, quickly adapt to wounds of different shapes and sizes, and achieve effective splicing and transfer of dressings when treating large wounds without relying on manual cutting and complicated operation processes. Solving this problem will greatly improve the applicability and efficiency of negative pressure drainage therapy, promote rapid wound healing, and improve the patient's treatment experience. Utility Model Content
[0006] The utility model discloses a negative pressure drainage dressing system with a splicing structure, which is suitable for wounds of different shapes and sizes and solves the problem that the existing dressings are inconvenient to use due to standardized production and cannot be used for special parts or large-area wounds.
[0007] A negative pressure drainage dressing system with a splicing structure, the dressing system is spliced by a first dressing unit and a second dressing unit, the first dressing unit and the second dressing unit are in the shape of a square or a regular hexagon, and the shape of the spliced dressing system includes but is not limited to: a positive direction, a rectangle, a right angle, a T-shape, a cross, and a honeycomb.
[0008] Furthermore, the first dressing unit and the second dressing unit are composed of a dressing and a first drainage tube and a second drainage tube passing through and wrapped inside the dressing.
[0009] Furthermore, two ends of the first drainage tube and the second drainage tube have a first splicing structure and a second splicing structure respectively.
[0010] Furthermore, the first splicing structure is located inside the first drainage tube, and its port is located on the side of the dressing; the second splicing structure is located outside the second drainage tube, and its port is perpendicular to and protrudes from the side of the dressing.
[0011] Furthermore, the second splicing structure is composed of an insertion surface with a gradually decreasing diameter and a fixing surface perpendicular to the insertion surface, and the distance between the fixing surface and the insertion surface is 1-2 cm; the shape of the first splicing structure matches the second splicing structure.
[0012] Furthermore, a silicone ring is fixed on the side surface of the insertion surface in a semi-inwardly recessed manner.
[0013] Furthermore, a plurality of spring buckles are fixed on the side surface of the fixing surface, and a plurality of spring buckle grooves are provided inside the first splicing structure to match the spring buckles.
[0014] Furthermore, it also includes a plugging head, which is composed of an end face and a plug column perpendicular to the end face, and the plugging head is inserted into the exposed drainage tube around the dressing system and fixed.
[0015] Furthermore, the side surface of the plug has several semi-recessed fixed silicone rings.
[0016] Furthermore, the cross-sectional shape of the plug is trapezoidal or rectangular.
[0017] In order to achieve the above purpose, the following technical solutions are adopted:
[0018] By designing a unit structure, the units can be spliced into various regular or irregular shapes during use to meet the care needs of wounds of various sizes and shapes. At the same time, it is very friendly to industrialization. It only needs to customize large, medium and small sizes, as well as two corresponding unit structures, which can cover most clinical use scenarios. For example, for small wounds such as fingers, small units can be directly spliced. Of course, the specific size can be customized according to clinical needs.
[0019] The splicing structure is simple and can be fixed by plugging. At the same time, considering the scene that needs to be strengthened, spring buckles and spring buckle grooves can be used for fixing;
[0020] By adding a plugging head, it is easier to create a negative pressure environment;
[0021] The silicone ring can both fix and assist in sealing, which has a dual effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the examples of the implementation of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only representative embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.
[0032] If you want the dressing to be flexibly applied to various parts, including but not limited to: regular flat wounds, wounds on fingers, wounds on armpits and neck, and large wounds. At this time, the standardized production of dressings is not a big problem for regular flat wounds, but if it is used on fingers or other parts, it needs to be cut. At this time, the dressing and drainage tube need to be cut separately, and then the dressing and drainage tube are combined into a new dressing for use.
[0033] Based on the above limitations, if the dressing and the drainage tube can be designed as a whole into a unitized module, there is no need for cutting and self-assembly, and only the module units need to be spliced together to form a specific shape. Example 1
[0034] A negative pressure drainage dressing system with a splicing structure, such as Figure 1 and Figure 2 As shown, the first dressing unit 10 and the second dressing unit 20 can be spliced into various shapes. The first dressing unit 10 and the second dressing unit 20 are negative pressure dressings (such as sponges) respectively having a first drainage tube 110 and a second drainage tube 210 built therein.
[0035] The two ports of the first drainage tube 110 and the second drainage tube 210 have a first splicing structure 100 at one end and a second splicing structure 200 at the other end; the first drainage tube 110 and the second drainage tube 210 are connected together by the first splicing structure 100 and the second splicing structure 200, and then the first dressing unit 10 and the second dressing unit 20 are also connected together.
[0036] In order to ensure that the joints can be tightly connected together and adjacent dressings can fit tightly together, the first splicing structure 100 is located inside the dressing, and the second splicing structure 200 protrudes from the dressing and is located outside the dressing. After the second splicing structure 200 is inserted into the first splicing structure 100, the first dressing unit 10 and the second dressing unit 20 can fit tightly together.
[0037] In order to facilitate insertion and fixation, the cross section of the second splicing structure 200 (perpendicular to the direction of the hollow pipe of the drainage tube) is a trapezoidal shape, whose diameter is smaller than the diameter of the drainage tube and gradually decreases in the direction away from the drainage tube, so that the second splicing structure 200 forms an insertion surface 211 for easy insertion; in addition, it continues to extend vertically 1-2 cm forward at the smallest diameter to form a fixing surface 212, which plays a fixing effect. Of course, correspondingly, there is an insertion portion formed by an inward depression inside the first splicing structure 200, which matches the size of the insertion surface 211 and the fixing surface 212. Example 2
[0038] For relatively flat wound surfaces, the fixed connection strength of Example 1 is sufficient. However, for wound surfaces with large curvature or unevenness, higher requirements are placed on the fixing strength between units. This example optimizes the fixing strength based on Example 1.
[0039] First, the first reinforcement is to embed a silicone ring 400 inwardly on the surface of the insertion surface 211, such as Figure 3 As shown, after the silicone ring 400 is inserted into the insertion surface 211 , it can play both a fixing effect and a sealing effect.
[0040] Secondly, the second reinforcement is that a plurality of spring buckles 220 are fixed on the side surface of the fixing surface 212. Correspondingly, there are spring buckle grooves 120 inside the first splicing structure 100. After insertion, Figure 4 As shown, the spring hook 220 is snapped into the spring hook groove 120 to achieve fixation.
[0041] The two strengthening methods mentioned above can be selected either one or used together. Example 3
[0042] The dressing can be spliced through the unit structure of Example 1 or Example 2, but the drainage tube ports are exposed on all sides after the splicing is completed. Although a film layer will be sealed on the dressing when negative pressure drainage is used to create a negative pressure environment; however, if the exposed ports on all sides can be sealed, it will be easier to establish a negative pressure environment.
[0043] In this embodiment, the plugging head 300 suitable for plugging is as follows: Figure 5As shown, the plugging head 300 as a whole is composed of an end face 310 and a plug 320 perpendicular to the end face. A plurality of silicone rings 400 are embedded inwardly on the side surface of the plug 320. The function of the silicone ring 400 is the same as that in Example 2.
[0044] Regarding the shape of the plug 320, it can be a shape with an inclined side surface, which is adapted to the first splicing structure 100; another shape of the plug 320 is cylindrical, and the diameter of the cylinder is the same as the inner diameter of the second drainage tube 210. When in use, the second splicing structure 200 exposed outside the periphery is cut off with scissors, and then the plug 320 is inserted into the second drainage tube 210 and fixed. Example 4
[0045] On the basis of the above-mentioned embodiments, this embodiment demonstrates two shapes of dressing units, splicing combination methods and applicable scenarios of the utility model.
[0046] like Figure 6 and Figure 7 As shown, a first shape of dressing unit of the present invention is shown, namely, a square unit 500. The square unit 500 can be spliced into a square or rectangular shape, which can be used for ordinary, relatively flat wound surfaces, or large-area wound surfaces.
[0047] The square units 500 can also be spliced into right-angle, T-shape, cross-shape and the like, which can be used on wounds on the hands or underarms, neck and the like.
[0048] Of course, it can also be spliced into irregular shapes according to the shape of the wound.
[0049] like Figure 8 As shown, a second shape of dressing unit of the present invention is shown, which is a regular hexagonal unit 600. The regular hexagonal unit 600 can be spliced into various irregular shapes such as honeycomb and heart shapes, which are suitable for wounds in the armpits, neck, etc.
[0050] The reason why the present invention only selects the square unit 500 and the regular hexagonal unit 600 is that they can be spliced into various shapes, the splicing method is simple, and no gaps will be generated after splicing.
[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description of the present invention and its drawings should also be included in the protection scope of the present invention.
