Description

Technical Field

[0001] The utility model relates to the technical field of fixing patches, in particular to a catheter fixing patch. Background Art

[0002] Currently, many catheters are used when treating patients in hospitals, such as drainage tubes, infusion tubes, etc. These catheters need to be fixed on the human body, usually with fixed adhesive stickers. First, the base sticker is pasted and fixed on the patient's skin, and then the catheter is pasted and fixed on the base sticker with tape.

[0003] When the catheter is fixed by the above adhesive tape, the bottom tape has poor air permeability, and the skin adhered to the bottom tape has difficulty in heat dissipation, sweat is produced and not easy to evaporate, and sweat accumulates on the skin surface, which is easy to cause skin allergies or even blister rupture for patients with sensitive skin. In addition, the traditional adhesive tape has a large adhesion area to the skin, which is not comfortable for the patient, and when the bottom tape is torn off, it causes excessive traction on the skin, aggravating the patient's pain. Utility Model Content

[0004] The utility model aims to provide a catheter fixing patch with good ventilation effect and high comfort level, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A catheter fixing patch comprises a base patch pad, one large surface of the base patch pad is a fixing surface, the other large surface is an adhesion surface, a plurality of first air holes are evenly distributed on the base patch pad, each of the first air holes penetrates the fixing surface and the adhesion surface, a fixing pad is fixed in the middle of the fixing surface of the base patch pad, second air holes are evenly distributed on the fixing pad, a fixing adhesive patch for fixing the catheter is adhered to the surface of the fixing pad, and the four top corners of the base patch are all rounded.

[0007] It can be seen that the catheter can be fixed by sticking the adhesive surface of the base pad on the skin of the patient at the required position, and then using the fixing adhesive sticker to stick and fix the catheter on the fixing pad. Since the first air holes are evenly distributed on the base pad and the second air holes are evenly distributed on the fixing pad, the breathability of the entire catheter patch is increased, which is helpful for the heat dissipation of the covered skin and the evaporation of sweat, improves the comfort of the patient's skin surface, and is suitable for patients with sensitive skin. In addition, the catheter is fixed to the fixing pad using the high-lift platform method using the fixing adhesive sticker, which makes the catheter fixation more firmly and stably. The four corners of the base pad are rounded, which not only increases the overall aesthetics, but also ensures that the base pad stuck on the skin is not easy to curl up and fall off.

[0008] Furthermore, a plurality of adhesive portions are arranged on the adhesive surface of the base pad, and the plurality of adhesive portions are adjacent to the four side edges of the base pad and are arranged at intervals, and there is a gap between two adjacent adhesive portions.

[0009] The base patch can be adhered to the skin using the adhesive portion, and the adhesive portions are spaced apart along the four edges of the base patch to provide a multi-point adhesion effect, which not only ensures the firmness of the adhesion, but also reduces the adhesion coverage area compared to traditional guide rail patches, which not only improves the patient's comfort but also makes it easier to tear off the base patch. Secondly, there is a gap between two adjacent adhesive portions, which facilitates lateral air circulation and further improves the breathability effect.

[0010] Furthermore, the adhesive portions at the four top corners of the adhesive surface are in the shape of an elongated arc, and the curvature of the four adhesive portions matches the curvature of the four rounded corners of the base pad, and the remaining adhesive portions are all in the shape of long strips.

[0011] The adhesive parts at the four corners are in the shape of an extended arc, which are adapted to the four rounded corners of the base pad, and the extended design can ensure the firmness of the adhesion between the four corners of the base pad and the skin. Combined with the design of the four rounded corners of the base pad, the four corners of the base pad are not easy to warp up, and the remaining adhesive parts are in the shape of long strips, providing additional adhesion effect, which complements the adhesion effect of the extended arc-shaped adhesive parts, ensures the firmness of the adhesion of the base pad, makes it difficult for the catheter to fall off the patient, and further improves the fixation effect of the catheter.

[0012] Furthermore, a through hollow slot is provided at the center of the base pad, and the fixing pad covers the hollow slot.

[0013] By arranging hollow slots on the base pad, the area on the base pad covered by the fixed pad can be set to be hollow, avoiding the double-layer arrangement of the base pad and the fixed pad resulting in a large overall thickness and reduced ventilation effect. Combined with the second ventilation hole arranged on the fixed pad, the ventilation effect of the area on the base pad covered by the fixed pad is effectively guaranteed.

[0014] Furthermore, each adhesive portion is pasted with a protective film, and the protective film is made of polyethylene film.

[0015] By sticking a protective film on the adhesive part, the protective film is made of polyethylene film, which has good waterproof and dustproof effects. Before use, it can provide protection for the adhesive part to prevent the adhesive part from losing its stickiness. When using, just tear off the protective film from the adhesive part.

[0016] Furthermore, the base pad is made of non-woven fabric material, and each viscose part is made of medical hydrogel.

[0017] The base pad is made of non-woven fabric, so that the base pad itself has good breathability. Combined with the first breathable hole opened thereon, its breathability and heat dissipation effect is further improved. In addition, the non-woven fabric is soft and skin-friendly, and it is more comfortable when in contact with the patient's skin. Medical hydrogel has a high water content and good breathability and moisturizing properties. Using medical hydrogel as the viscose part can effectively reduce the pressure of friction on the patient's skin.

It is suitable for patients with sensitive skin.

[0020] 2. The utility model utilizes the adhesive part to stick the base patch pad on the skin. The adhesive parts are arranged at intervals along the four side edges of the base patch pad to provide a multi-point adhesion effect, which not only ensures the firmness of the adhesion, but also reduces the adhesion coverage area compared to the traditional guide rail patch, which not only improves the patient's comfort but also makes it convenient to tear off the base patch pad. Secondly, there is a gap between two adjacent adhesive parts, which is conducive to lateral air circulation and further improves the ventilation effect.

[0021] 3. The utility model designs the adhesive parts at the four corners of the base pad into an elongated arc shape, which is adapted to the four rounded corners of the base pad, and the elongated design can ensure the firmness of the adhesion between the four corners of the base pad and the skin. Combined with the design of the four rounded corners of the base pad, the four corners of the base pad are not easy to curl up, and the remaining adhesive parts are long strips, providing additional adhesion effect, which complements the adhesion effect of the elongated arc-shaped adhesive parts, ensures the firmness of the adhesion of the base pad, makes it difficult for the catheter to fall off the patient, and further improves the fixation effect of the catheter.

[0022] 4. The utility model arranges hollow notches on the base pad, so that the area on the base pad covered by the fixed pad can be set to be hollow, avoiding the double-layer arrangement of the base pad and the fixed pad resulting in a large overall thickness and reduced ventilation effect. Combined with the second ventilation holes arranged on the fixed pad, the ventilation effect of the area on the base pad covered by the fixed pad is effectively guaranteed.
