Description

Technical Field

[0001] This utility model relates to a dressing, specifically a medical non-woven fabric dressing. Background Technology

[0002] Medical dressings are basic consumables widely used in clinical medicine and home care. Their core functions are to cover wounds, protect wounds, fix instruments or catheters, absorb exudate, and provide a certain degree of barrier protection. To achieve these functions and ensure that the dressing adheres firmly to the patient's skin surface during use, preventing displacement or detachment, most medical dressings have a pressure-sensitive adhesive layer coated on the skin contact surface of their substrate (such as non-woven fabric, film, hydrocolloid, foam, etc.).

[0003] However, currently widely used medical dressings present a significant technical challenge in practical use, especially in scenarios requiring repeated changes (such as chronic wound care, long-term intravenous infusion fixation, frequent vital sign monitoring, and stoma care), impacting patient experience and skin health: each removal and replacement of the dressing causes varying degrees of irritation and potential damage to the patient's skin. This irritation primarily stems from mechanical damage and pain during removal, manifesting in the following ways:

[0004] Adhesion Challenges: To ensure sufficient adhesion and tack, dressings typically require strong initial tack and peel strength. When removing the dressing, the adhesive forces between the adhesive and the stratum corneum and skin surface microstructures (such as hair, pores, and skin texture) must be overcome. This direct physical peeling process inevitably creates pulling, stretching, and even shear stress on the skin surface.

[0005] Stratum corneum damage: The outermost layer of the skin, the stratum corneum, is an important barrier. Rough or repeated peeling operations can directly cause stratum corneum cells to be stuck, peeled off, or damaged, temporarily weakening the skin barrier function, making it fragile, dry, and even causing visible micro-damage or peeling.

[0006] Pain and discomfort: The mechanical pulling during the peeling process, especially for people with delicate skin (such as newborns, infants, and the elderly), sensitive skin, or poor skin conditions (such as eczema and dermatitis), often causes significant pain, stinging, or burning sensations, which significantly reduces patient comfort and compliance. Utility Model Content

[0007] In view of the technical problems of mechanical damage and peeling pain in the existing technology when the dressing needs to be changed repeatedly, this utility model provides a medical non-woven fabric dressing.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example:

[0030] See Figure 1 and Figure 2 This embodiment discloses a medical non-woven fabric dressing, including a fixing patch 10, a dressing bag 20, and a limiting rope 30. The fixing patch 10 is made of a soft material, generally non-woven fabric. The fixing patch 10 has a ring structure with a hollow structure in the middle. Adhesive is provided on one side of the fixing patch 10 for bonding with the patient's skin. Hereinafter, the side of the fixing patch 10 with adhesive is referred to as the adhesive side, and the other side is the non-adhesive side.

[0031] The dressing bag 20 is located in the hollow structure in the middle of the fixation patch 10, and the dressing bag 20 contains a dressing for treatment, and the dressing has micropores densely distributed on at least one side of it.

[0032] One end of the limiting rope 30 is fixedly mounted on the non-adhesive side of the fixing patch 10, and the other end of the limiting rope 30 is detachably connected to the other side of the non-adhesive side of the fixing patch 10. The limiting rope 30 can also press against the dressing bag 20.

[0033] In use, the adhesive side of the fixation patch 10 is attached to the outer periphery of the area to be treated on the patient. Then, the dressing bag 20 is placed in the hollow structure in the middle of the fixation patch 10. The end of the limiting rope 30 is then connected to the non-adhesive side of the fixation patch 10, thereby fixing the dressing for treatment to the area to be treated on the patient.

[0034] In this embodiment, when a dressing needs to be changed, the dressing bag 20 can be removed simply by disassembling the end of the limiting rope 30. This avoids repeated adhesion and separation of the adhesive from the patient's skin, thereby preventing mechanical damage and peeling pain.

[0035] In one specific embodiment:

[0036] To alleviate the discomfort caused by prolonged adhesion of the fixation patch 10 to the patient's skin, several ventilation holes are provided on the fixation patch 10 to improve the breathability of the adhesion point and achieve timely heat dissipation.

[0037] In another specific embodiment:

[0038] To improve the stability of the dressing bag 20, the limiting rope 30 is made of an elastic material, and the natural length of the elastic rope (when not under external force) is required to be less than or equal to the width of both sides of the fixing patch 10.

[0039] In another specific embodiment:

[0040] The medical non-woven dressing also includes a connecting block 40 and a limiting block 50. The connecting block 40 has a T-shaped structure, and one end of the connecting block 40 is fixedly mounted on one end of the limiting rope 30.

[0041] The limiting block 50 has an L-shaped structure. One end of the limiting block 50 is fixedly set on the non-adhesive surface of the fixing sticker 10, so that the other end of the limiting block 50 is suspended.

[0042] Two limiting blocks 50 with a gap are provided at adjacent positions of the fixing sticker 10, and the suspended ends of the two limiting blocks 50 and the non-adhesive surface of the fixing sticker 10 form a connecting groove. During installation, the other two ends of the connecting block 40 are respectively locked in the two limiting blocks 50, so that the connecting block 40 can be detachably connected in the connecting groove.

[0043] In this embodiment, the connection block 40 and the connection groove are matched to enable the quick installation and removal of the limiting rope 30.

[0044] In another specific embodiment:

[0045] Each end of the fixing patch 10 and each end of the dressing bag 20 is provided with a Velcro 60, and the two Velcro 60s are used to assist in the positioning of the dressing bag.

[0046] In another specific embodiment:

[0047] The fixing sticker 10 is equipped with multiple limiting ropes 30. By setting multiple limiting ropes 30, the stability of the auxiliary material bag can be improved.

[0048] 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.
