It should be noted that, as those skilled in the art will appreciate, the medical wearing apparatus referred to herein includes, but is not limited to, blood glucose monitoring sensor devices, traditional Chinese medicine applications, radiotherapy positioning applications, infusion needle applications, and the like.

In order to realize the above thought, the utility model provides a fixing patch for fixing medical wearing equipment, wherein the fixing patch comprises a reinforcing layer, an adhesive layer and a protective layer which are sequentially laminated from top to bottom; the reinforcing layer is at least attached to the outer edge of the bonding layer so as to prevent the edge of the bonding layer from warping; the adhesive layer is used for adhering to the medical wearing equipment and/or the skin surface of the user; the protective layer comprises a plurality of removing force parts, wherein the removing force parts are used for exposing the middle area and/or the side area of the adhesive layer when being stressed. From this, through setting up the enhancement layer in the top of tie coat, not only can guarantee that the user will fix when the cover of pasting is established in the periphery of medical wearing equipment at the singlehanded and make the pasting of pasting in the week side of medical wearing equipment with pasting, can guarantee moreover that the user is at the in-process of installing the pasting of fixing, the difficult emergence of adhesive layer warp to make the adhesive layer paste on user's skin surface more smoothly, thereby can effectively guarantee the fixed effect of pasting. In addition, the protective layer comprises a plurality of removing force parts, so that a user can conveniently remove the protective layer step by step to expose the adhesive layer, and the fixing patch is more convenient for the user to install by one hand.

Further, the reinforcing layer also has at least one slit. Thus, the slits are generally provided so that after the adhesive layer is adhered to the skin surface of the user, the user can easily tear the reinforcing layer entirely from the upper surface of the adhesive layer at the slits and remove it therefrom.

Further, the adhesive layer has a fixing location for the medical wearing device to pass through or attach to the medical wearing device, the fixing location being matched with the outer contour of the medical wearing device. Therefore, the fixing position is arranged on the adhesive layer, so that a user can accurately position the adhesive layer when the solid adhesive is sleeved on the periphery of the medical equipment by one hand, and deflection is not easy to occur.

Further, the protective layer comprises a first protective layer and a second protective layer, wherein the first protective layer is provided with a first removing force part for exposing the middle area of the adhesive layer when being stressed, the second protective layer is provided with a second removing force part for exposing the side area of the adhesive layer when being stressed, and the first removing force part extends in a direction away from the middle area of the adhesive layer and is erected on the lower side of the second removing force part. Therefore, the setting can be more convenient for a user to remove the protective layer by one hand, and further the user can finish the bonding of the bonding layer by one hand.

Referring to fig. 1 to fig. 4, fig. 1 is a schematic front perspective view of a fixing patch according to some embodiments of the present utility model; FIG. 2 is a schematic view of a back side perspective view of a fastening patch according to some embodiments of the present utility model; FIG. 3 is a schematic exploded view of a patch according to some embodiments of the present utility model; fig. 4 is a schematic view showing the distribution of the adhesive in the fixing patch on the plastic film according to some embodiments of the present utility model. As shown in fig. 1 to 4, in the present embodiment, the fixing patch includes a reinforcing layer 100, an adhesive layer 200, and a first protective layer 300, which are laminated in this order from top to bottom; the reinforcing layer 100 has a first through hole 110 penetrating through both axial ends thereof, the adhesive layer 200 has a second through hole 230 penetrating through both axial ends of the adhesive layer 200, the second through hole 230 is a fixing position matching with the outer contour of the medical wearing apparatus 500 (see fig. 8 b), and the first through hole 110 is coaxially arranged with the fixing position; the adhesive layer 200 includes a plastic film 210 and an adhesive 220 disposed on the lower surface of the plastic film 210, the adhesive 220 being distributed in a lattice-like manner on the lower surface of the plastic film 210; at least one side of the first protective layer 300 is bent downward and is disposed apart from the adhesive layer 200 to constitute a first removing force portion 320. Thus, in the use process of the fixing patch, the first protective layer 300 may be removed through the first removing portion 320, then the fixing patch after the removal of the first protective layer 300 is sleeved on the outer circumference of the medical wearable apparatus 500 through the second through hole 230, and then the subsequent adhering step is performed.

Although the drawings in the present embodiment illustrate the case where the cross section of the second through hole 230 is substantially rectangular, it should be understood by those skilled in the art that this is not a limitation of the present utility model, and the cross section of the second through hole 230 may be other shapes, and a fixing patch having the second through hole 230 matching the outer contour of the medical wearing apparatus may be selected as needed for fixing the medical wearing apparatus according to different types of medical wearing apparatuses.

Specifically, the reinforcing layer 100 may be a reinforcing film or a reinforcing paper capable of providing a certain deformation resistance to the fixing patch, and the first protective layer 300 may be a release paper or a release film, which is not limited in the present utility model.

Further, in order to improve the fixing effect of the fixing patch provided in the present embodiment on the medical wearable apparatus 500, a fit tolerance between the second through hole 230 and the outer contour of the medical wearable apparatus 500 is within ±0.50mm.

In one exemplary embodiment, the plastic film 210 is a PU film (polyurethane film). Since the PU film (polyurethane film) has excellent elasticity, and still has excellent water repellency and excellent moisture permeability in the case of extremely thin thickness, by using the PU film as the substrate for carrying the adhesive 220 of the adhesive layer 200, not only the water repellency of the adhesive layer 200 but also the moisture permeability of the adhesive layer 200 can be improved, and thus the comfort of a user wearing the fixing patch provided by the present utility model can be effectively improved. In addition, since the PU film (polyurethane film) also has good transparency, the invisible effect can be better achieved.

In one exemplary embodiment, adhesive 220 is a skin friendly gel. Thus, by using the skin-friendly adhesive as the adhesive 220 of the adhesive layer 200, the comfort of the user wearing the fixing patch provided by the present utility model can be further improved.

With continued reference to fig. 3, as shown in fig. 3, the inner diameter of the second through hole 230 is smaller than the inner diameter of the first through hole 110. Therefore, the medical wearing device 500 can not only effectively penetrate through the adhesive layer 200 and the reinforcing layer 100, but also reduce the contact area between the reinforcing layer 100 and the adhesive layer 200, so that after the adhesive layer 200 is fixed on the skin surface of a user, the user can remove the reinforcing layer 100 by one hand, and the fixing patch provided by the utility model is more convenient to use.

Referring to fig. 1 and 5, fig. 5 is a schematic structural diagram of a reinforcing layer 100 in a fixing patch according to some embodiments of the present utility model. As shown in fig. 1 and 5, in an exemplary embodiment, the reinforcing layer 100 further has at least one first slit 120, one end of the first slit 120 extends to the outer edge of the reinforcing layer 100, and the other end of the first slit 120 extends to one side of the first through hole 110. Thus, by providing at least one first slit 120 on the reinforcing layer 100, it is more convenient for a user to easily tear and remove the reinforcing layer 100 entirely from the upper surface of the adhesive layer 200 at the first slit 120 after the adhesive layer 200 is adhered. It should be noted that, although the present embodiment is described taking the reinforcing layer 100 having one first slit 120 as an example, it should be understood by those skilled in the art that this is not a limitation of the present embodiment, and in other embodiments, the fixing patch provided in the present embodiment may further have two, three or more first slits 120.

Preferably, in this embodiment, the reinforcing layer 100 has a first slit 120. Thus, by providing one first slit 120, the user can tear and remove the reinforcing layer 100 entirely from the upper surface of the adhesive layer 200 by the first slit 120 only once.

Further, as shown in fig. 1 and 5, a side of the first through hole 110 adjacent to the first slit 120 is provided with a first V-shaped sharp corner 130, and the first slit 120 extends to a first sharp point 131 of the first V-shaped sharp corner 130. Thus, by providing the first V-shaped sharp corner 130 at one side of the first through hole 110 and providing the first slit 120 at the first sharp point 131 of the first V-shaped sharp corner 130, it is possible to more easily recognize the position of the first slit 120 by the user and to tear and remove the reinforcing layer 100 entirely from the upper surface of the adhesive layer 200 by the first slit 120.

With continued reference to fig. 1 and 5, as shown in fig. 1 and 5, the inner corners 111 of the first through holes 110 are rounded. Therefore, by setting the inner corners 111 of the first through holes 110 to be rounded transitions, the reinforcing layer 100 can be effectively prevented from breaking at the inner corners 111 of the first through holes 110 in the process of removing the reinforcing layer 100 from the upper surface of the adhesive layer 200, so that the user can be effectively ensured to smoothly tear the entire reinforcing layer 100 from the upper surface of the adhesive layer 200 and remove the same.

With continued reference to fig. 3, 6 and 7, fig. 6 is a front view of a fixing patch according to some embodiments of the present utility model; fig. 7 is an enlarged partial schematic view of the portion a in fig. 6. As shown in fig. 3, 6 and 7, in an exemplary embodiment, both sides of the first protective layer 300 are bent downward and are separately disposed from the adhesive layer 200 to form two first removing force portions 320, the protective layer further includes two second protective layers 400 disposed in one-to-one correspondence with the two first removing force portions 320 of the first protective layer 300, the second protective layers 400 are disposed between the adhesive layer 200 and the first protective layer 300, and for each second protective layer 400, a side of the second protective layer 400 away from the other second protective layer 400 is connected to the adhesive layer 200 to cover a corresponding side region of the adhesive layer 200, and a side of the second protective layer 400 close to the other second protective layer 400 is bent downward to form a second removing force portion 410. In some embodiments, the second protective layer 400 may be connected to the first protective layer 300 and the adhesive layer 200 by opposite sides, respectively, and further preferably, the edge of the second protective layer 400 extends outwards (not shown) with respect to the first protective layer 300 to distinguish the first protective layer 400 from the second protective layer 300; in other embodiments, the second protective layer 400 may be connected to the first protective layer 300 and the adhesive layer 200 by the same side, i.e., the second protective layer 400 is bent and angled, so that the side is connected to the first protective layer 300 and the adhesive layer 200 and the first protective layer 300 and the adhesive layer 200 are separated (as shown in fig. 7), thereby easily removing the second protective layer 400 and the first protective layer 300 step by step. Specifically, the second protective layer 400 may be a release paper or a release film.

Thus, the lower surface of the middle region of the adhesive layer 200 may be covered by the first protective layer 300, and the lower surfaces of both side regions of the adhesive layer 200 may be covered by the two second protective layers 400. Further, by providing the segmented protective layer (including the first protective layer 300 and the second protective layer 400), the process of attaching the adhesive layer 200 can be divided into three attaching steps: a first step of attaching, namely removing the first protective layer 300 and attaching the intermediate adhesive area of the adhesive layer 200 to the medical wearing apparatus 500 and/or the skin surface of the user; a second step of attaching, namely removing the second protective layer 400 on one side and attaching the exposed adhesive area on one side of the adhesive layer 200 to the medical wearing apparatus 500 and/or the skin surface of the user; a third attaching step of removing the second protective layer 400 on the other side and attaching the exposed other side attaching region of the attaching layer 200 to the medical wearing apparatus 500 and/or the skin surface of the user. It can be seen that by providing the segmented protective layers (including the first protective layer 300 and the second protective layer 400), the user can more conveniently complete the bonding of the bonding layer 200 by one hand. In addition, in some embodiments, for each second protection layer 400, since a side of the second protection layer 400 close to the other second protection layer 400 is also bent downward, a second removing portion 410 may be provided for the user, so that the user may remove the second protection layer 400 from the lower surface of the adhesive layer 200 with one hand more conveniently.

With continued reference to fig. 3, as shown in fig. 3, in an exemplary embodiment, the surface area of the second removing force portion 410 is smaller than the surface area of the first removing force portion 320, and the second removing force portion 410 is exposed after the first removing force portion 320 is removed. Therefore, the first removing portion 320 is protruded outwards relative to the second removing portion 410, so that the first protective layer 300 can be removed from the lower surface of the adhesive layer 200 by a single hand of a user, and the second protective layer 400 can be effectively prevented from being erroneously removed during the removal process.

It should be understood by those skilled in the art that, in other embodiments, the protective layer may also include two second protective layers 400, without the first protective layer 300, where two second protective layers 400 extend from two sides of the adhesive layer 200 to the middle region and cover corresponding sides of the adhesive layer 200, and where the two second protective layers 400 are folded down after joining the middle region to form a removing force portion, where the removing force portion allows the user to remove the two second protective layers 400 in steps, for example, removing one second protective layer 400 to expose a left side region and half of the middle region of the adhesive layer 200, then applying force to make the exposed adhesive layer 200 more closely adhere to the upper surface of the self-adhesive tape on the bottom of the medical wearable apparatus 500 and/or to the skin surface of the user, and then removing the other second protective layer 400 to expose a right side region of the adhesive layer 200 and half of the middle region, and applying force to make the newly exposed adhesive layer 200 partially adhere more tightly, and completing the adhesion of the adhesive layer 200 in two steps, thereby facilitating the user's one-hand operation and ensuring the adhesion, aesthetic effect and firmness.

It should be noted that, in order to attach the adhesive tape, the adhesive tape is generally attached from inside to outside, that is, the adhesive tape is sequentially attached in a direction away from the medical wearable apparatus 500, so that the attaching degree is higher, the probability of lifting/wrinkling is reduced, the removing force portion is generally easy to apply force to the patient and has the same extending direction as the corresponding adhesive layer 200 to be exposed, and in other embodiments, the adhesive layer 200 is exposed stepwise in other sequences to achieve the effect sought after by the present utility model, which should be regarded as the protection scope of the present utility model when not explicitly shown.

With continued reference to fig. 2 and 3, as shown in fig. 2 and 3, in the present embodiment, the first protection layer 300 has a third through hole 310 penetrating through two axial ends thereof, the third through hole 310 is coaxially disposed with the second through hole 230, and an inner diameter of the third through hole 310 is smaller than or equal to an inner diameter of the second through hole 230. Thus, by providing the third through hole 310 on the first protective layer 300, it is possible to reduce the area of the first protective layer 300 affected by the adhesive layer 200, and reduce the force required to be applied when removing the first protective layer 300, thereby more facilitating the user to remove the first protective layer 300 from the lower surface of the adhesive layer 200 with one hand. By setting the inner diameter of the third through-hole 310 to be smaller than or equal to the inner diameter of the second through-hole 230, it is ensured that the first protective layer 300 can effectively cover the lower surface of the middle region of the adhesive layer 200, to better protect the adhesive 220 located on the lower surface of the middle region of the adhesive layer 200, and to reduce resistance to removal of the first protective layer 300.

The specific installation process of the fixing patch provided in this embodiment will be described with reference to fig. 8a to 8 h. As shown in fig. 8a to 8h, the specific installation process of the fixing patch provided in this embodiment includes the following steps: step one, removing the first protective layer 300 from the lower surface of the adhesive layer 200; aligning the fixing patch with the first protective layer 300 removed with the medical wearable apparatus 500, and sleeving the fixing patch with the first protective layer 300 removed on the periphery of the medical wearable apparatus 500, so as to bond the middle bonding area (namely the primary bonding area marked in fig. 8 d) of the bonding layer 200 with the upper surface of the self-carried adhesive patch at the bottom of the medical wearable apparatus 500 and/or the skin surface of the user; step three, removing the second protective layer 400 on one side, and adhering the exposed adhesive area (i.e. the secondary adhesive area marked in fig. 8 e) on one side of the adhesive layer 200 to the upper surface of the self-adhesive tape on the bottom of the medical wearable apparatus 500 and/or the skin surface of the user; step four, removing the second protective layer 400 on the other side, and adhering the exposed adhesive area on the other side (i.e. the third adhesive area marked in fig. 8 f) of the adhesive layer 200 to the upper surface of the self-adhesive tape on the bottom of the medical wearable apparatus 500 and/or the skin surface of the user; and step four, removing the reinforcing layer 100 and smoothing the adhesive layer 200 to finish the installation of the fixing patch.

Please continue to refer to fig. 9, which is a diagram illustrating a wearing effect of the fastening patch according to some embodiments of the present utility model. As shown in fig. 9, after the fixing patch provided in this embodiment is installed, the adhesive layer 200 may be smoothly adhered to the skin surface of the user, so as to perform a secondary fixing function on the medical wearing apparatus.

Fig. 10 to 13 are schematic perspective views of a hollow area 240 in a fixing patch according to other embodiments of the present utility model in an unstretched state; FIG. 12 is a schematic exploded view of a patch according to other embodiments of the present utility model; fig. 11 is a schematic perspective view illustrating a stretched state of a hollowed-out area 240 in a fixing patch according to other embodiments of the present utility model; fig. 13 is a wearing effect diagram of a fixing patch according to other embodiments of the present utility model. As shown in fig. 10 to 13, the main difference between the fixing patch provided in this embodiment and the fixing patch provided in the previous embodiment is that in this embodiment, the fixing portion is a hollowed-out area 240 disposed on the adhesive layer 200, and the hollowed-out area 240 can be stretched to wrap the medical wearable apparatus 500. Because the hollowed-out area 240 (i.e. the fixing position) can be upwards protruded after being stretched, the medical wearing equipment 500 can be wrapped, and further the medical wearing equipment 500 can be effectively prevented from shaking in the fixing position, so that the fixing effect of the fixing patch provided by the embodiment on the medical wearing equipment can be effectively improved.

Preferably, an adhesive 220 is disposed on a lower surface of at least a portion of the hollowed-out region 240. Therefore, the fixing effect of the fixing patch provided by the embodiment on the medical wearing equipment can be further effectively guaranteed through the arrangement.

Further, as shown in fig. 12, the fixing patch provided in this embodiment also has the following differences from the fixing patch provided in the first embodiment: in the present embodiment, the first protective layer 300 does not have the third through-holes 310 in the first embodiment. Therefore, the first protection layer 300 can cover the lower surface of the hollowed-out area 240, so as to protect the lower surface of the hollowed-out area 240.

Further, as shown in fig. 10 to 13, the hollowed-out area 240 includes a first wrapping portion 241, a plurality of second wrapping portions 242, and a plurality of holes 243, where the first wrapping portion 241 and the second wrapping portion 242 are disposed to intersect and enclose to form the plurality of holes 243. Therefore, the arrangement can ensure that the hollowed-out area 240 has certain strength so as to prevent the hollowed-out area 240 from breaking in the stretching process, and ensure that the hollowed-out area 240 (i.e. the fixing position) can be smoothly and upwardly protruded after being stretched so as to smoothly wrap the medical wearing equipment 500.

Preferably, as shown in fig. 10 and 13, the first wrapping portion 241 is disposed along the length direction of the adhesive layer 200, and the second wrapping portion 242 is disposed along the width direction of the adhesive layer 200. Therefore, the arrangement not only can facilitate the processing of the hollowed-out area 240 on the adhesive layer 200, but also can ensure that the hollowed-out area 240 has a certain strength so as to prevent the hollowed-out area 240 from breaking in the stretching process.

Referring to fig. 10 to 11, as shown in fig. 10 to 11, in an exemplary embodiment, the inner contour of the first through hole 110 matches the outer contour of the hollow area 240 in a stretched state, and the reinforcing layer 100 further has a plurality of fourth through holes 140 spaced around the outer periphery of the first through hole 110. Because the inner contour of the first through hole 110 is matched with the outer contour of the hollow area 240 in the stretched state, that is, the inner diameter of the first through hole 110 is slightly larger than the outer contour size of the hollow area 240 in the stretched state, a certain constraint effect can be achieved on the medical wearing device 500 through the first through hole 110, so that the medical wearing device 500 is prevented from breaking the hollow area 240, and meanwhile, the adhesive layer 200 is prevented from wrinkling in the process of inserting the medical wearing device 500 into the hollow area 240. In addition, by providing the reinforcing layer 100 with the plurality of fourth through holes 140 spaced around the outer circumference of the first through hole 110, it is further ensured that the adhesive layer 200 does not wrinkle during the process of inserting the medical wearing apparatus 500 into the hollowed-out area 240.

Preferably, as shown in fig. 10 to 11, the inner corners 141 of the fourth through holes 140 are rounded. Therefore, in the process of removing the reinforcing layer 100 from the upper surface of the adhesive layer 200, the reinforcing layer 100 is effectively prevented from being broken at the inner corner 141 of the fourth through hole 140, so that the user can be effectively ensured to smoothly tear the reinforcing layer 100 from the upper surface of the adhesive layer 200 and remove the reinforcing layer.

Further, as shown in fig. 10 to 11, the fixing patch provided in this embodiment is different from the fixing patch provided in the previous embodiment in that, in this embodiment, the reinforcing layer 100 has at least one second slit 150, one end of the second slit 150 extends to the outer edge of the reinforcing layer 100, and the other end of the second slit 150 extends to the side of one of the fourth through holes 140 away from the first through hole 110. Thus, the present embodiment can facilitate the user to easily tear the whole reinforcing layer 100 from the upper surface of the adhesive layer 200 and remove it by the second slits 150 after the adhesive layer 200 is adhered by providing at least one second slit 150 on the reinforcing layer 100. It should be noted that, although the present embodiment is described by taking the reinforcing layer 100 having one second slit 150 as an example, it should be understood by those skilled in the art that this is not a limitation of the present embodiment, and in other embodiments, the fixing patch provided in the present embodiment may further have two, three or more second slits 150.

Preferably, in this embodiment, the reinforcing layer 100 has a second slit 150. Thus, by providing one second slit 150, the user can tear the reinforcing layer 100 entirely from the upper surface of the adhesive layer 200 and remove it therefrom by only one operation.

Further, at least one of the fourth through holes 140 is provided with a second V-shaped sharp corner 160 at a side remote from the first through hole 110, one end of the second slit 150 extends to an outer edge of the reinforcing layer 100, and the other end of the second slit 150 extends to a second sharp point 161 of the second V-shaped sharp corner 160. As shown in fig. 12, a side of the fourth through hole 140, which is disposed corresponding to the second slit 150 and is away from the first through hole 110, is provided with a second V-shaped sharp corner 160, and the second slit 150 extends to a second sharp point 161 of the second V-shaped sharp corner 160. Thus, by disposing the second slit 150 at the second point 161 of the second V-shaped sharp corner 160, it is possible to more easily recognize the position of the second slit 150 by the user and to tear and remove the reinforcing layer 100 entirely from the upper surface of the adhesive layer 200 by the second slit 150.

Further, as shown in fig. 10 to 11, in the present embodiment, the reinforcing layer 100 further has at least one third slit 170, one end of the third slit 170 extends to a portion of the reinforcing layer 100 between two adjacent fourth through holes 140, and the other end of the third slit 170 extends to the first through hole 110. Thus, by further providing at least one third slit 170 on the reinforcing layer 100, the present embodiment can further facilitate the user to easily tear the reinforcing layer 100 entirely from the upper surface of the adhesive layer 200 and remove it from the second slit 150 and the third slit 170 after the adhesive layer 200 is adhered. It should be noted that, although the present embodiment is described as having one third slit 170 in the reinforcing layer 100, it should be understood by those skilled in the art that this embodiment is not limited thereto, and in other embodiments, the fixing patch provided in the present embodiment may further have two, three or more third slits 170.

Preferably, in this embodiment, the reinforcing layer 100 has a third slit 170. Thus, by providing the third slit 170, not only the user can tear the reinforcing layer 100 entirely from the upper surface of the adhesive layer 200 and remove it by only one operation from the second slit 150 and the third slit 170, but also the reinforcing effect of the reinforcing layer 100 on the adhesive layer 200 can be ensured.

It should be noted that, as will be understood by those skilled in the art, in order to avoid redundancy, only the differences between the patch provided by this embodiment and the patch provided by the previous embodiment are described in detail, but the differences between the patch provided by this embodiment and the patch provided by the previous embodiment are not described, and the relevant content of the differences between the patch provided by this embodiment and the patch provided by the previous embodiment may be referred to the relevant description in the previous embodiment.
