Description

Technical Field

[0001] This utility model relates to the field of plaster technology, and in particular to a plaster that is easy for a single person to operate. Background Technology

[0002] Plasters are one of the important dosage forms for external treatment in traditional Chinese medicine. They have the advantages of being convenient to use, having a long-lasting effect, and being non-invasive. They are widely used in the treatment of diseases in orthopedics, dermatology, and other fields. In traditional techniques, plasters generally include a base layer made of non-woven fabric. One side of the base layer is coated with ointment and colloid, and a peelable release paper is attached to the colloid for protection. When using, the release paper is peeled off to expose the colloid, and then the plaster is applied to the affected skin. There are generally two specific methods for this procedure.

[0003] The first method involves completely peeling off the release paper and then holding the plaster with both hands to apply it. During this process, the operator's hands are very likely to come into contact with the adhesive of the plaster, causing contamination and stickiness. Moreover, for larger, softer plasters, after completely peeling off the release paper, the plaster itself is very prone to curling and sticking together. Because the adhesive on the plaster is very sticky, the plaster becomes difficult to restore after sticking together, affecting its use. Especially when used by a single person, the operator often cannot simultaneously stretch the plaster to prevent it from sticking together and accurately apply the plaster to the affected area.

[0004] The second method involves first peeling off a portion of the release paper, then sticking the exposed adhesive onto the skin. The release paper is then peeled off gradually, with each peeled section revealing new adhesive that is then applied to the skin. This method avoids the plaster curling or sticking together, but it generally requires another person to operate. A single person needs to hold the plaster while slowly peeling off the release paper. In areas that are inherently difficult to access, such as the lumbar spine or shoulder blades, this is very troublesome for a single person.

[0005] Based on this, the applicant believes there is a need to provide a plaster that avoids the above problems and is easy for a single person to operate. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of existing plasters being difficult for a single person to operate and prone to self-adhesion.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A medicated plaster that is easy for one person to use, comprising: A base layer, one side of which has a colloidal layer and is coated with an ointment; A plurality of release papers are provided, wherein the adhesive layer is divided into multiple regions, and the plurality of release papers are sequentially bonded to the adhesive layer corresponding to the multiple regions and covering the entire adhesive layer. Each release paper has a first edge located within the base layer and a second edge aligned with the edge of the base layer. The first edge of each release paper has a first handle portion that overlaps the surface of the adjacent release paper and is not bonded to the adhesive layer.

[0008] Preferably, a second handle portion extends from the second edge of each release paper outside the base layer.

[0009] Preferably, a third handle portion without a colloidal layer extends from the edge of the base layer.

[0010] Preferably, the colloidal layer is divided into multiple regions along the length of the rectangle, or the colloidal layer is divided into multiple regions along the width of the rectangle.

[0011] Preferably, the base layer is circular, and the colloidal layer is divided into multiple fan-shaped regions along the circumferential direction of the circle.

[0012] Preferably, the base layer has an easy-tear structure, and the base layer and its colloidal layer are divided into multiple regions by the easy-tear structure.

[0013] Preferably, the easy-tear structure is a continuous pre-cut line.

[0014] Preferably, the first handle portion on each of the release papers occupies 10% to 20% of its area.

[0015] Preferably, the first pull portion on each release liner and the overlapping portion of the adjacent release liner are connected by an easy-peel adhesive with a peel strength less than the adhesion strength between the release liner and the adhesive layer.

[0016] Preferably, each of the first handle portions is provided with an indicator mark to indicate the correct direction for separating its corresponding release paper.

[0017] The medicated plaster provided by this utility model is easy for a single person to operate and has the following significant advantages compared with the prior art: 1. Multiple release papers are used to cover the adhesive layer, and each release paper has a handle for easy application of force by the operator. This allows the operator to remove the release paper in stages and gradually apply the plaster to the skin, effectively preventing the plaster from self-adhesive and folding.

[0018] 2. Each release paper has two types of handles, which can be peeled off from different directions. When used by a single person, the direction of force can be selected to peel off the release paper according to the actual situation.

[0019] 3. The base layer edge has a third handle that does not adhere to the adhesive layer. When the ointment has been partially adhered to the skin surface, the operator can use the third handle to keep the ointment stretched with one hand and easily peel off the release paper with the other hand.

[0020] 4. The plaster is divided into multiple areas by easy-tear lines and each area is covered with release paper. Depending on the size and location of the affected area, the plaster can be divided into multiple pieces and then combined and pasted to create a shape that better suits the patient's condition.

[0021] 5. The first handle is attached to the adjacent release paper with an easy-peel adhesive, which not only avoids premature peeling of the release paper due to friction or accidental contact during transportation, but also does not affect the user's manual operation.

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] like Figure 1 As shown, this utility model provides an easy-to-use plaster for single-person operation. It improves upon existing plasters by retaining a soft and resilient base layer made of non-woven fabric or similar materials. A medicated ointment and adhesive substance for treating or relieving corresponding symptoms are applied to one side of the base layer to form a gel layer. The core improvement lies in dividing the originally monolithic release paper into several independent units, which are then placed over the gel layer. This divides the gel layer into different areas. Each release paper has a first edge located within the base layer area and a second edge aligned with the base layer edge. This design facilitates peeling and prevents adjacent... The release liner creates gaps, exposing the adhesive layer. Specifically, each release liner has a first handle extending outward from its first edge, which can overlap and cover the surfaces of adjacent release liner but not adhere to the adhesive layer. By peeling off the release liner sequentially and then gradually applying the adhesive, the soft base layer can be effectively prevented from curling and self-adheding after the release liner is completely torn off. Furthermore, for ease of operation, a second handle is provided on the second edge of each release liner, allowing the user to peel off the release liner from different directions. When used by a single person, the user can choose the direction from which to apply more force to peel off the release liner.

[0028] The above is the basic technical solution of this utility model. The following detailed embodiments will be used to further illustrate it.

[0029] Example 1 like Figures 1 to 3 As shown, this embodiment provides a plaster that is easy for a single person to operate, including a base layer 1, an adhesive layer 2, and three release papers 3.

[0030] The base layer 1 is made of non-woven fabric and has a rectangular structure with a length of 150 mm and a width of 100 mm. One side of the base layer 1 has a colloidal layer 2 made of medical pressure-sensitive adhesive, which has good adhesion and breathability. A paste, a traditional Chinese medicine preparation, is uniformly coated on the colloidal layer 2. This paste has the effects of promoting blood circulation, removing blood stasis, reducing swelling, and relieving pain. Furthermore, pores 9 are uniformly distributed on the base layer 1. These pores 9 are present in subsequent embodiments and will not be described again hereafter.

[0031] The colloidal layer 2 is divided into three regions along the length of the base layer 1: a first region, a second region, and a third region, each region being approximately 50 mm in length. Three release papers 3 cover the three regions respectively, and completely cover the colloidal layer 2.

[0032] Each release liner 3 is a rectangular structure made of silicone paper with good anti-stick properties. Each release liner 3 has a first edge 31 located within the base layer 1 and a second edge 32 aligned with the edge of the base layer 1.

[0033] Importantly, each release liner 3 has a first handle portion 4 at its first edge 31. The first handle portion 4 overlaps the surface of the adjacent release liner 3 but is not bonded to the adhesive layer 2. The width of the first handle portion 4 is 15 mm, occupying approximately 15% of the area of ​​the release liner 3. The first handle portions 4 between adjacent release liner 3 are lightly connected by an easy-peel adhesive with a peel strength of approximately 0.5 N / 25 mm, significantly less than the adhesion strength between the release liner 3 and the adhesive layer 2 (approximately 2.0 N / 25 mm).

[0034] Each release paper 3 extends a second handle 5 at the second edge 32. The second handle 5 is located outside the base layer 1 and extends for 10 mm, making it easy for the operator to pinch with their fingers.

[0035] A third handle portion 6 extends from one side edge of the base layer 1. The third handle portion 6 uses the same non-woven fabric material as the base layer 1 but does not have a gel layer 2. It is semi-circular in shape to fit the shape of a thumb.

[0036] Each first handle 4 is marked with an arrow-shaped indicator, pointing in the direction that needs to be peeled off, making it easy for the operator to identify the correct peeling direction.

[0037] How to use: S1: First, take out the plaster and observe the indicator mark on the first pull handle 4 on the first release paper 3 to confirm the peeling direction; S2: Pinch the first pull part 4 or the second pull part 5 of the first release paper 3 with your thumb and forefinger, and gently lift it up in the direction of the indicator mark. Since the first pull part 4 is connected to the adjacent release paper 3 with an easy-to-peel adhesive, the peeling strength is small, and the first release paper 3 can be easily peeled off from the colloid layer 2. S3: After completely peeling off the first release paper 3, accurately apply the exposed first area of ​​the colloid layer 2 to the affected skin and gently press it with your palm to ensure full adhesion. S4: Hold the third pull handle 6 on both sides of the base layer 1 with both hands to keep the plaster flat and prevent it from curling or folding. S5: Pinch the first pull part 4 of the second release paper 3, peel off the second release paper 3 in the same way, and stick the adhesive layer 2 of the second area onto the skin; S6: Finally, peel off the release paper 3 one by one and completely adhere the colloid layer 2 of the third area to the skin.

[0038] Specifically, in S6, when a single user operates the plaster, one hand holds the third handle 6 and applies slight force to stretch the plaster. Then, the other hand uses either the first handle 4 or the second handle 5 to peel off the release paper 3, depending on the direction of convenient force application. (See reference) Figure 5 and Figure 6 This simulates a scenario where a single person applies a plaster to their shoulder blade.

[0039] Figure 5 The traditional method of using medicated plasters involves peeling off a portion of the release paper, sticking the adhesive layer at point A onto the skin, and then using both hands. One hand applies pressure at point B, peeling off the remaining portion of the release paper in the direction indicated by the arrow. Since it is impossible to apply pressure at point C, the other hand needs to press the base layer gradually in the direction of the arrow to ensure a smooth adhesion. This ensures that the adhesive layer is stably and evenly adhered to the skin. If the affected area is in the lumbar spine, this action is relatively simple, but if it is in the scapula area, this action becomes very difficult and inconvenient for single-person use.

[0040] and Figure 6 To use this utility model, first peel off one release paper 3, and stick the exposed part, namely the adhesive layer 2 at point A, onto the skin. Then, hold the third pull handle 6 with one hand and apply force in the direction of the arrow to ensure that the plaster body is stretched. Then, use the other hand to apply force in the direction of the arrow through the second pull handle 5 to peel off the remaining two release papers 3. This action is simpler than the traditional technical solution.

[0041] This embodiment utilizes a three-part release paper (3) method, allowing the operator to peel off the release paper (3) while gradually applying the plaster to the skin, effectively preventing the plaster from self-adhesively folding. The first handle (4) and second handle (5) provide two different peeling directions, allowing the operator to choose the most convenient method based on the application area. The third handle (6) enables single-person operation, allowing one hand to keep the plaster flat while the other hand peels off the release paper (3), greatly improving operational convenience.

[0042] Example 2 This embodiment is similar in basic structure to Embodiment 1, with the main difference being the partitioning direction of the colloid layer 2 and the number of release papers 3.

[0043] The base layer 1 is also a rectangular structure, with a length of 120mm and a width of 180mm. The colloid layer 2 is divided into four regions along the width of the base layer 1, each region being approximately 45mm wide. Four release papers 3 cover the four regions respectively.

[0044] The first handle portion 4 of each release paper 3 occupies approximately 12% of its area. The first handle portions 4 of adjacent release papers 3 are connected by an easy-peel adhesive with a peel strength of approximately 0.3 N / 25 mm. The extension length of the second handle portion 5 is 10 mm, and the base layer 1 has symmetrical third handle portions 6 on both sides.

[0045] How to use: S1: This embodiment is suitable for application to wider areas such as the waist or back. The operator can first roughly position the plaster on the affected area, and then gradually peel off the release paper 3 from the middle to both sides; S2: First, peel off either of the two release papers 3 in the middle and attach the corresponding area to the center of the affected area; S3: Hold the third pull handle 6 with one hand to keep the plaster flat, and peel off the adjacent release paper 3 with the other hand to spread the adhesive layer 2 outward and stick it on. S4: Peel off the remaining release paper 3 one by one, and gradually complete the pasting of the entire plaster from the center to both sides.

[0046] The technical advantages of this embodiment are: the width-divided design makes the plaster more suitable for use on wide application areas. The application method from the center outwards better conforms to the curves of the human body, avoiding wrinkles or air bubbles. The division into four zones allows for more precise application and can adapt to different shapes and sizes of affected areas.

[0047] Example 3 This embodiment provides a circular plaster structure suitable for areas such as joints.

[0048] like Figure 7 and Figure 8 As shown, the base layer 1 has a circular structure with a diameter of 100 mm. The colloidal layer 2 is divided into four sector-shaped regions along the circumferential direction of the circle, and the four sector-shaped release papers 3 cover the four sector-shaped regions respectively.

[0049] The first edge 31 of each fan-shaped release paper 4 is located on the boundary line between adjacent fan-shaped areas, and the first handle part 4 is located on the radially outer side of the first edge 31, overlapping on the surface of the adjacent release paper 4, occupying about 10% of the area of ​​each release paper 4.

[0050] The second edge 31 of each fan-shaped release paper 3 is aligned with the circumferential edge of the base layer 1. A second handle portion 5 may or may not be provided on it. Each first handle portion 4 is printed with a clockwise or counterclockwise arc-shaped arrow indicator to indicate the peeling direction. The first handle portions 4 of adjacent release papers 3 are connected by an easy-peel adhesive. A third handle portion 6 may not be provided for circular plasters.

[0051] How to use: S1: Place the round plaster with the center aligned with the joint area; S2: Select a release paper 3 as the starting point, pinch its first pull handle 4, and peel it off in the direction of the markings; S3: Apply the first fan-shaped area of ​​the gel layer 2 that has been peeled off to the skin; S4: In a clockwise or counterclockwise direction, peel off the adjacent release paper 3 in sequence, and immediately attach each fan-shaped area to the skin after peeling it off; S5: After completing the application of all fan-shaped areas, press the entire plaster with your palm, especially the edges, to ensure full adhesion.

[0052] The technical advantages of this embodiment: The circular fan-shaped partition design allows the plaster to perfectly conform to the spherical or curved shape of the joint area. Peeling off the release paper 3 gradually from the center outwards reduces wrinkles during application, ensuring the plaster adheres smoothly and evenly. The four fan-shaped areas ensure ease of use and accommodate skin stretching during joint movement, improving wearing comfort.

[0053] Example 4 This embodiment provides a separable plaster with an easy-tear structure, which can be used flexibly according to actual needs. Specifically, based on the previous embodiment, an easy-tear line is provided to substantially divide the base layer 1 of the plaster and the colloid layer 2 into three regions. Figure 1 and Figure 4 As shown, the easy-tear line 7 is a continuous pre-cut line set along the width direction of the base layer 1, dividing the base layer 1 into three rectangular areas. The depth of the pre-cut line is 70% of the thickness of the base layer 1, ensuring both easy tearing and the stability of the overall structure before tearing. The colloid layer 2 and the paste 3 are also divided into three areas along the position of the pre-cut line. Furthermore, for further convenience, V-shaped easy-tear openings 8 are provided at both ends of the easy-tear line 7 on the plaster body.

[0054] How to use: When used as a whole: S1: Do not tear along the easy-tear line 7; use the plaster as a whole. S2: Following the method in Example 1, gradually peel off the three release papers and stick them to the affected area one by one from one end to the other.

[0055] When used separately: S1: Determine the number of areas to be used based on the actual area and shape of the affected area; S2: Pinch the plaster on both sides of the easy-tear line 7 and apply force in different directions to tear the plaster body along the easy-tear line 7 into three independent small pieces. Each small piece of plaster has a corresponding release paper 3. S3: The three small plasters can be used individually or combined to form a pattern that suits the shape of the affected area, such as an I-shape or a cross shape or other irregular shapes. These two shapes are also suitable for use on joints and can even stay close to the skin during joint bending better than round plasters.

[0056] The technical advantages of this embodiment: The easy-tear line 7 makes the plaster separable, allowing for flexible adjustment of the application area according to the actual condition of the affected area. For small areas or irregularly shaped affected areas, only a portion can be used, avoiding waste. The combination of multiple plasters can also adapt to special areas such as joints and the spine where specific areas need to be avoided or adhered to. The design of dividing each area into two small release sheets further improves the convenience of single-person operation, and even small, independent areas can avoid self-adhesion problems.

[0057] Example 5 This embodiment is an improvement on Embodiments 2 and 4. Since the base layer 1 has a large area, each area is covered by two release papers 3, and each release paper 3 has two vertical first handles 4. The advantage of this design is that the small plaster after being torn off can also be pasted by peeling off the two small release papers 3 in sequence.

[0058] Example 6 This embodiment provides a more user-friendly plaster based on Embodiment 1. The base layer 1 is rectangular, with a length of 150mm and a width of 100mm. The adhesive layer 2 is divided into three regions along its length, each region being approximately 50mm long. Three release papers 3 cover the three regions respectively.

[0059] The key feature of this embodiment lies in the design of the first handle portion 4. The first handle portion 4 occupies 18% of the area of ​​each release liner 3, which is relatively large and provides ample gripping space. The bonding area between the first handle portion 4 and the easy-peel adhesive between the first handle portion 4 and the adjacent release liner 3 is small, and the peel strength is controlled at 0.2N / 25mm, ensuring that the operator can peel it off very easily.

[0060] Furthermore, the surface of each first handle portion 4 is frosted to increase friction and facilitate finger grip. Additionally, the first handle portion 4 is a different color from the main body of the release paper 3; the main body is white, while the first handle portion 4 is light blue for easy identification. The second handle portion 5 extends 12mm in length, and the ends of the extended portion are rounded to prevent damage during use and carrying.

[0061] Furthermore, the indicator markings on each first handle 4 feature embossed arrow patterns, which can be visually identified and also sensed by touch, making them especially suitable for elderly people with poor eyesight.

[0062] The usage method is basically the same as in Example 1, but because the first handle part 4 has a larger area, enhanced friction, and more distinct colors, it is easier to operate. Especially in low-light environments or when the operator's vision is poor, the raised indicator marks and color contrast can help with quick identification and correct operation.

[0063] The technical advantages of this embodiment are as follows: By optimizing the area, friction characteristics, color recognition, and tactile markings of the first handle portion 4, the ease of operation and success rate are greatly improved. It is especially suitable for use by the elderly, visually impaired individuals, or in special environments. The larger area of ​​the first handle portion 4 also reduces the possibility of accidentally peeling off multiple release papers 3 simultaneously.

[0064] It should be noted that the various embodiments of this utility model can be implemented individually or in combination. For example, the circular plaster can also be divided into multiple fan-shaped small plasters by easy-tear lines, or the user experience of the first handle can be enhanced.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
