Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a protective dressing and drainage tube fixing device. Background Art

[0002] Draining body fluids during or after surgery is a common practice in the medical field. During drainage, the drainage tube needs to be fixed on the skin, which can easily cause the drainage tube to press on the skin for a long time, causing discomfort to the patient. Based on this, in the prior art, a dressing is usually applied to the skin surface below the drainage tube. The dressing is used to reduce the pressure of the drainage tube on the skin. However, when using traditional foam dressings with self-adhesive adhesive to protect the wound and the skin around the wound bandage, it has blind spots for protection. Based on this, a new solution is urgently needed to solve the above problem. Summary of the Invention

[0003] The purpose of the present invention is to provide a protective dressing and drainage tube fixing device to solve the problems existing in the above-mentioned prior art and improve patient comfort and safety.

[0004] To achieve the above object, the present invention provides the following solutions:

[0005] The present invention provides a protective patch, comprising: a buffer pad with a self-adhesive edge, at least part of the edge of the buffer pad does not have the self-adhesive edge, and the self-adhesive edge can enable the protective patch to be applied to the human skin when adhered to the human skin.

[0006] In some embodiments, when the protective dressing is applied to human skin, the edge of the buffer pad without the self-adhesive edge is used to contact the edge of the wound bandage.

[0007] In some embodiments, the buffer pad is a rectangular structure, and at least one side edge does not have the self-adhesive edge.

[0008] In some embodiments, only one edge of the buffer pad does not have the self-adhesive edge.

[0009] In some embodiments, the buffer pad is made of foam material.

[0010] In some embodiments, the self-adhesive edges are provided on only two opposite edges of the buffer pad.

[0011] The present invention also provides a drainage tube fixing device, comprising a body surface fixing patch and the protective dressing as described above, wherein the body surface fixing patch is used to fix and press the drainage tube onto the buffer pad.

[0012] In some embodiments, a plurality of the body surface fixing patches are provided.

[0013] In some embodiments, the body surface fixing patch is provided with one.

[0014] Compared with the prior art, the present invention has achieved the following technical effects:

[0015] When using the protective dressing and drainage tube fixing device provided by the present invention, the edge of the protective dressing without the self-adhesive edge is aligned with the bandage on the wound, and is as close to the bandage as possible to reduce the gap between the bandage and the protective dressing, thereby reducing the dead angle area, or even completely eliminating the dead angle area. The drainage tube is then placed on the protective dressing. The presence of the protective dressing can reduce the pressure of the drainage tube on the human skin, thereby improving the patient's comfort. In addition, the drainage tube fixing device provided by the present application also includes a body surface fixing patch, and the body surface fixing patch is used to fix the drainage tube on the protective dressing, thereby limiting the freedom of movement of the drainage tube, avoiding the phenomenon that the drainage structure inserted into the human body stretches the patient's wound due to the movement of the drainage tube, and avoiding the phenomenon of the tube falling off, thereby improving the safety of the patient.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The purpose of the present invention is to provide a protective dressing and drainage tube fixing device to solve the problems existing in the above-mentioned prior art and improve patient comfort and safety.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] First, some technical terms involved in the embodiments of this application are introduced.

[0025] Foam dressing: A medical cushioning pad made of polyurethane or polyvinyl alcohol material used to isolate the drainage tube from contact with the skin.

[0026] Self-adhesive: medical grade adhesive.

[0027] Self-adhesive edge: Film with self-adhesive adhesive on one side.

[0028] Surface fixation patch: a drainage tube fixation device with an adhesive base.

[0029] For ease of understanding, a foam patch with self-adhesive edges on all four sides in the prior art is used as an example for illustration.

[0030] Since the foam dressing in the prior art has self-adhesive edges on all four sides, when in use, the foam dressing needs to be applied to one side of the patient's wound, and there is a bandage on the wound, and the bandage is replaced frequently, but the foam dressing and the drainage tube do not need to be replaced. Based on this, the self-adhesive edge of the foam dressing cannot stick to the surface of the bandage, which affects the replacement of the bandage. Therefore, in the prior art, when using the foam dressing to reduce the pressure of the drainage tube on the skin, the foam dressing is usually applied to one side of the bandage. However, due to the presence of the self-adhesive edge, the main structure of the foam dressing (i.e., the cushion that plays a buffering role, corresponding to the present application) There must be a certain distance between the cushion pad in the following embodiments and the bandage. This distance is the protection blind spot area. The skin in the protection blind spot area will still be compressed by the drainage tube, thereby reducing the patient's comfort. Based on this, medical staff usually reduce the distance between the bandage and the pad as much as possible. The most extreme case is: the outer edge of the self-adhesive edge and the outer edge of the bandage are in contact with each other, but they do not block each other. This can reduce the protection blind spot area as much as possible, thereby reducing the pressure on the patient's skin to a certain extent. However, it is still not ideal. Based on this, the present invention provides the following embodiments to overcome the above-mentioned defects.

[0031] The following combination Figures 1 to 3 , describing embodiments of the present invention.

[0032] Example 1

[0033] This embodiment provides a protective dressing 1, comprising: a buffer pad 11 with a self-adhesive edge 12, at least part of the edge of the buffer pad 11 does not have the self-adhesive edge 12, and the self-adhesive edge 12 can enable the protective dressing 1 to be applied to the human skin when adhered to the human skin.

[0034] When the protective dressing 1 provided by the present invention is in use, the edge of the protective dressing 1 not provided with the self-adhesive edge 12 is aligned with the bandage 2 on the wound, and is as close to the bandage 2 as possible to reduce the distance between the bandage 2 and the protective dressing 1, thereby reducing the dead angle area 5, or even completely eliminating the dead angle area 5. Then, the drainage tube 3 is placed on the protective dressing 1. The presence of the protective dressing 1 can reduce the pressure of the drainage tube 3 on the human skin, thereby improving the patient's comfort.

[0035] In some embodiments, when the protective dressing 1 is applied to human skin, the edge of the buffer pad 11 without the self-adhesive edge 12 is used to contact the edge of the wound bandage 2 .

[0036] This embodiment limits the function of the edge of the cushion pad 11 without the self-adhesive edge 12, thereby further improving the comfort of the patient.

[0037] In some embodiments, the buffer pad 11 is a rectangular structure, and at least one edge thereof does not have the self-adhesive edge 12 .

[0038] This embodiment provides a structure of the cushion pad 11. The cushion pad 11 has a regular structure, is easy to manufacture, and has a low manufacturing cost. It is understood that in some examples, the cushion pad 11 may also be circular, oval, or even have a special structure due to the need to be applied to the skin surface of some special structures of the human body.

[0039] It should be noted that "at least one side edge does not have a self-adhesive edge 12" includes multiple situations, such as only one side edge does not have a self-adhesive edge 12, or only two opposite edges are provided with self-adhesive edges 12, as long as it can play the role of applying the buffer pad 11 on the human skin and has one side edge for contacting the bandage 2.

[0040] In some embodiments, the cushion pad 11 is made of foam material. Compared to the foam dressing in the prior art, the protective dressing 1 in this embodiment only eliminates the self-adhesive edge 12 on one side of the cushion pad 11.

[0041] This embodiment provides a specific material composition of a cushion pad 11. The foam material has a good cushioning effect. In some examples, cotton material or other materials with cushioning effect can also be used.

[0042] In some embodiments, the buffer pad 11 is made of flexible material.

[0043] In some embodiments, one side of the cushion pad 11 is covered with a whole film, the edge of which extends beyond the outer edge of the cushion pad 11 , and a self-adhesive adhesive is provided on the inner side of the extended portion of the film to form a self-adhesive edge 12 .

[0044] It is understandable that the above is only a specific method for forming the self-adhesive edge 12 . In other embodiments, it is only necessary to connect a film to the edge of the buffer pad 11 and then provide self-adhesive glue on the inner side of the film.

[0045] Example 2

[0046] This embodiment provides a drainage tube fixing device, including a body surface fixing patch 4 and the protective dressing 1 described in the first embodiment. The body surface fixing patch 4 is used to fix and press the drainage tube 3 onto the buffer pad 11.

[0047] When the drainage tube fixing device provided by the present invention is in use, the edge of the protective dressing 1 without the self-adhesive edge 12 is aligned with the bandage 2 at the wound, and is as close to the bandage 2 as possible to reduce the gap between the bandage 2 and the protective dressing 1, thereby reducing the dead angle area 5, or even completely eliminating the dead angle area 5, and then the drainage tube 3 is placed on the protective dressing 1. The presence of the protective dressing 1 can reduce the pressure of the drainage tube 3 on the human skin, thereby improving the patient's comfort. In addition, the drainage tube fixing device also includes a body surface fixing patch 4. In this embodiment, the body surface fixing patch 4 can be used to fix the drainage tube 3 on the protective dressing 1, thereby limiting the freedom of movement of the drainage tube 3, avoiding the phenomenon that the drainage structure inserted into the human body stretches the patient's wound due to the movement of the drainage tube 3, and avoiding the phenomenon of the tube falling off, thereby further improving the patient's comfort.

[0048] In some embodiments, a plurality of body surface fixing patches 4 are provided.

[0049] In this embodiment, the drainage tube 3 can be fixed by a plurality of body surface fixing patches 4, thereby improving the stability of the fixation of the drainage tube 3, avoiding the phenomenon of the tube falling off, and thus improving safety.

[0050] In some embodiments, one body surface fixing patch 4 is provided.

[0051] In this embodiment, the drainage tube 3 can be fixed by a body surface fixing patch 4 .

[0052] The body surface fixing patch 4 is a film with self-adhesive adhesive on one side. The body surface fixing patch 4 can compress the drainage tube and stick to the cushion.

[0053] The number of body surface fixing patches 4 needs to be set according to needs.
