Description

Technical Field

[0001] This utility model relates to a medical dressing, specifically to a dressing that can relieve discomfort when applied. Background Technology

[0002] Medical dressings (such as wound dressings, electrode pads, medicated plasters, monitoring sensor patches, etc.) are widely used medical devices in clinical medicine. Their core functions usually rely on close and long-term adhesion to the patient's skin surface to achieve purposes such as fixation, drug delivery, signal acquisition, or wound protection.

[0003] However, most medical dressings in the prior art, especially those that rely on adhesive matrix (such as pressure-sensitive adhesive) to achieve skin fixation, have a significant clinical drawback: prolonged continuous application can severely hinder the skin's normal physiological heat dissipation process.

[0004] This obstacle mainly stems from:

[0005] Physical barrier effect: The patch itself and its adhesive layer form a relatively sealed covering, which directly blocks the heat exchange (conduction, convection, radiation) between the skin surface and the external environment.

[0006] Moisture buildup: The sweat that the skin continuously secretes in a closed environment (both non-vaporizable and visibly sweating) cannot be effectively evaporated through the patch, resulting in a significant increase in the humidity of the local microenvironment.

[0007] The combined effect of impaired heat exchange and moisture accumulation directly leads to an abnormal increase in skin temperature (local heat accumulation) and a high-humidity microenvironment at the application site. This abnormal "heat-humidity" microenvironment triggers a series of adverse physiological reactions:

[0008] Impaired skin barrier function: High temperature and humidity can accelerate the overhydration of the stratum corneum, soften or even destroy the lipid structure of the stratum corneum, and weaken its physical barrier function.

[0009] Increased risk of irritation and allergic reactions: A damaged skin barrier is more susceptible to penetration from the dressing material itself (such as adhesive monomers, residual solvents, additives) or irritants accumulated in sweat, potentially triggering contact irritant dermatitis or allergic contact dermatitis. Additionally, high temperatures can enhance the sensitizing properties of certain chemicals.

[0010] Risk of microbial growth: Warm and humid environments also provide favorable conditions for the overgrowth of resident bacteria or foreign pathogenic microorganisms on the skin surface, which may trigger or aggravate skin infections and inflammation.

[0011] Therefore, the impaired heat dissipation caused by prolonged application and the resulting local heat accumulation and high humidity environment are key contributing factors to allergic and irritant reactions such as erythema, itching, papules, blisters, and even erosion at the application site. This problem not only reduces patient comfort and compliance but may also affect treatment efficacy and even lead to complications such as secondary infections. It is a significant clinical challenge that urgently needs to be addressed in current adhesive medical dressing technology. Utility Model Content

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] Example:

[0040] See Figure 1 and Figure 2 This embodiment discloses a dressing that can alleviate discomfort from adhesive application, including a fixation patch 10, a dressing bag 20, a liquid tube 30, and a liquid storage bag 40. The fixation patch 10 has a ring structure, and adhesive is provided on one side of the fixation patch 10. This side of the fixation patch 10 is defined as the adhesive side, and the other side of the fixation patch 10 is the non-adhesive side.

[0041] The dressing bag 20 is filled with dressing material and is located in the middle of the fixing ring. The bag body of the dressing bag 20 is made of non-woven fabric, which can effectively allow the drug ingredients in the dressing to penetrate into the patient's wound.

[0042] Multiple liquid tubes 30 are provided on the adhesive surface of the fixing sticker 10. The liquid tubes 30 contain fluid for heat dissipation. All liquid tubes 30 are distributed at equal intervals and along the length of the fixing sticker 10.

[0043] The liquid storage bag 40 is elastic, is disposed on the non-adhesive surface of the fixing sticker 10, and is connected to all liquid tubes 30.

[0044] In this embodiment, by setting a liquid tube 30 on the patch and driving the liquid flow in the liquid tube 30 through the liquid storage bag 40, the heat at the patching location is carried away, thereby achieving the effect of auxiliary heat dissipation.

[0045] Preferably, the patch further includes a heat dissipation bag 50 and a return tube 60, wherein the heat dissipation bag 50 is disposed on the non-adhesive surface of the fixing patch 10, and the heat dissipation bag 50 is connected to all liquid tubes 30.

[0046] Specifically, the heat dissipation bag 50 and the liquid storage bag 40 are respectively connected to the two ends of the liquid pipe 30, and the return pipe 60 is set on the non-adhesive surface of the fixing sticker 10, and the two ends of the return pipe 60 are also connected to the heat dissipation bag 50 and the liquid storage bag 40 respectively.

[0047] In this technical solution, the liquid in the liquid pipe 30 and the return pipe 60 is driven by the liquid storage bag 40, thereby enabling timely replacement of the fluid in the liquid pipe 30 to achieve a continuous auxiliary heat dissipation effect. After the fluid temperature in the liquid pipe 30 increases, it is naturally dissipated after flowing into the heat dissipation bag 50 and the return pipe 60.

[0048] In another preferred embodiment, in order to reduce the pressure of the liquid tube 30 on the patient's wound and skin, the liquid tube 30 is configured with a flat rectangular cross-section, and the wider side of the liquid tube 30 contacts the patient's wound and skin.

[0049] In addition, to reduce the pressure of the liquid tube 30 on the patient's wound and skin, the following technical solution can be adopted: grooves are provided on both the fixation patch 10 and the dressing bag 20, and the liquid tube 30 is embedded in the grooves, so that the surface of the liquid tube 30 is flush with the surface of the fixation patch 10 and the dressing bag 20.

[0050] In another preferred embodiment, a liquid guide tube 70 is provided at each end of the adhesive surface of the fixing sticker 10. The two ends of the liquid tube 30 are connected to the two liquid guide tubes 70 respectively. The two liquid guide tubes 70 are respectively connected to the liquid storage bag 40 and the heat dissipation bag 50. In this embodiment, by setting the liquid guide tubes 70, it is beneficial to evenly distribute the fluid output from the liquid storage bag 40 to each liquid tube 30, and to gather the fluid in each liquid tube 30 into the heat dissipation bag 50.

[0051] Preferably, a forward flow check valve is provided in the liquid guide pipe 70 connected to the liquid storage bag 40. A return flow check valve is provided in the return pipe 60. By setting the forward flow check valve and the return flow check valve, the fluid in the liquid pipe 30, the heat dissipation bag 50, the return pipe 60 and the liquid storage bag 40 can be controlled to flow in a single reverse direction, that is, to flow sequentially in the liquid storage bag 40, the liquid pipe 30, the heat dissipation bag 50 and the return pipe 60, and finally flow back to the liquid storage bag 40 through the return pipe 60.

[0052] In another preferred embodiment, the surface of the heat dissipation bag 50 is provided with fins. By adding fins, the heat dissipation effect of the fluid at the heat dissipation bag 50 can be improved.

[0053] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
