Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to an underarm apocrine gland tracing device. Background Technology

[0002] Axillary osmidrosis, commonly known as "body odor," is a condition caused by the secretions produced by the apocrine glands in the armpits, which are then broken down by bacteria, resulting in a pungent odor. Treatment for axillary osmidrosis is currently divided into two main categories: surgical and non-surgical treatments. There are various surgical methods; generally, an incision of 1 cm or more allows for direct visualization or special techniques / devices to determine the distribution of the apocrine glands during surgery. Smaller incisions or non-surgical treatments cannot accurately determine the distribution of the apocrine glands.

[0003] To determine the distribution range of apocrine glands, the axillary iodine-starch test is currently performed. The specific experimental procedure is as follows: first, iodine is applied to the armpit, and after the iodine dries, starch is applied. When sweat is secreted, the iodine and starch will change color and develop when they come into contact with water. The distribution range of the apocrine glands can be determined by observing the area of ​​color change and development.

[0004] However, this method has the following drawbacks: 1. Applying iodine and starch is time-consuming and laborious, taking approximately 30 to 40 minutes in total. In winter, when sweat secretion is lower, the iodine and starch take even longer to change color. 2. The ratio of starch to iodine is not constant. The amount of starch and iodine applied depends entirely on technique and experience, resulting in uneven development in some areas and poor development in others, thus affecting the accuracy of determining the distribution range of apocrine glands. 3. To increase sweating, a thin film is applied to the skin after starch application. This film reduces sweat evaporation, locking in moisture and improving the development effect. However, the film is unstable and prone to displacement, causing starch or developing particles to shift, resulting in inaccurate display range and affecting the accuracy of determining the apocrine gland area. Utility Model Content

[0005] The present invention aims to provide an underarm apocrine gland tracing device to quickly and accurately display the distribution range of apocrine glands in a non-invasive manner.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an underarm apocrine gland tracing device, comprising a cover film, a developing reaction layer and a protective film, wherein the developing reaction layer is located between the cover film and the protective film, and the developing reaction layer is fixed on the cover film; the developing reaction layer contains solid iodine and starch.

[0007] The principle and advantages of this solution are as follows: the developing reaction layer is fixed on the cover film, and the protective film covers the developing reaction layer. The developing reaction layer is held in place by the cover film and the protective film. In this way, when not in use, the cover film and the protective film protect the developing reaction layer, preventing it from absorbing moisture from the air and becoming ineffective, thus improving the storage life of the developing reaction layer.

[0008] When using it, peel off the protective film from the cover film to expose the developing reaction layer. Place the cover film under the armpit, and the developing reaction layer will come into contact with the armpit skin. When the armpit sweats, the solid iodine and starch react with the sweat and change color, thus developing the reaction layer. Based on the area of ​​the reaction layer, the distribution range of the apocrine glands can be determined.

[0009] The beneficial effects of this solution are as follows: 1. This axillary apocrine gland tracing device is easy to use. After peeling off the protective film, it can be directly applied to the armpit for use. The operation is simple and convenient, and there is no trauma to the body. At the same time, compared with the development method in the prior art, there is no need to apply liquid iodine and starch, which greatly shortens the operation time (it can be completed in a few minutes), and improves the speed and efficiency of determining the distribution range of apocrine glands. 2. The covering film adheres to the skin and can effectively lock in sweat, reduce sweat evaporation, ensure that there is enough moisture for the iodine and starch reaction, shorten the reaction time, improve the development effect, and reduce the error in determining the distribution range of apocrine glands. 3. Compared with the prior art of applying iodine or starch by experience and technique, since this device can be manufactured and sold according to certain standards, it can be directly applied to the armpit for use. The amount of solid iodine and starch used is calculated and designed during production. The amount of solid iodine and starch used is relatively fixed, and the ratio of the two is relatively constant, avoiding the error caused by the inconsistency of the ratio of iodine and starch, thus making the development effect relatively stable.

[0010] Preferably, as an improvement, the developing reaction layer comprises a solid iodine layer and a starch layer bonded together.

[0011] Preferably, as an improvement, the solid iodine layer is fixed on the covering film, and the starch layer covers the solid iodine layer.

[0012] Thus, the starch layer covers the solid iodine layer, with the solid iodine layer located between the starch layer and the covering film, thereby reducing the exposure of the solid iodine layer, reducing iodine volatilization and failure, and improving the service life of the solid iodine layer.

[0013] Preferably, as an improvement, the cover film has an adhesive layer. This adhesive layer allows the cover layer to be directly bonded to the skin without the need for additional adhesive tape, making the application simpler and more stable. The adhesive layer fixes the cover layer to the skin, preventing displacement and thus ensuring a relatively fixed position of the developing reaction layer. This avoids displacement of the developing reaction layer and accurately displays the distribution range of apocrine glands, solving the problem of inaccurate determination of apocrine gland distribution caused by the displacement of developing substances in current methods.

[0014] Preferably, as an improvement, the adhesive layer surrounds the outer side of the developing reaction layer. This significantly improves the stability of the cover film adhering to the skin, while the adhesive layer surrounding the outer side of the developing reaction layer confines the developing reaction layer within the area surrounded by the adhesive layer, preventing displacement of the developing reaction layer relative to the cover layer, thereby accurately displaying the distribution range of apocrine glands.

[0015] Preferably, as an improvement, the developing reaction layer is in the form of a grid or scattered dots.

[0016] Preferably, as an improvement, at least one of the solid iodine layers is in the form of a grid or scattered pattern.

[0017] Therefore, the developing reaction layer or solid iodine layer can be designed as a grid or a scattered pattern. When a grid is used, the spacing between the grids can be set to a fixed spacing, and the grid width can be set to a fixed width. When a scattered pattern is used, the spacing between each scattered point can also be set to a fixed spacing. In this way, by visually observing the number of grids or scattered points corresponding to the developing area, it is convenient to measure the distance of the developing area.

[0018] Preferably, as an improvement, the cover film has multiple grooves, and the developing reaction layer sinks into the grooves.

[0019] Preferably, as an improvement, the covering film has multiple grooves, and at least the solid iodine layer is submerged in the grooves.

[0020] As a result, the developing reaction layer or the solid iodine layer sinks into the groove, thereby increasing the contact area between the developing reaction layer and the cover film, improving the fixation of the developing reaction layer and the cover film, and making it less likely for the developing reaction layer and the cover film to shift relative to each other. At the same time, the solid iodine layer sinking into the groove allows the groove to cover the solid iodine layer, thereby reducing the contact between the solid iodine layer and the outside air, which helps to reduce the volatilization of iodine and increase the accuracy of the experiment.

[0021] In addition, when the solid iodine layer is set in a grid or scattered pattern, the grooves on the covering film can adapt to the grid or scattered pattern on the solid iodine layer, so that the solid iodine layer can be placed in the grooves.

[0022] Preferably, as an improvement, the entire developing reaction layer is grid-like or dotted (not just the solid iodine layer is grid-like or dotted); the cover film has multiple through holes; the through holes are located between the grid gaps, or between the gaps of the multiple dots; the side of the cover film away from the developing reaction layer is covered with a sealing film.

[0023] Therefore, during use, after development, the sealing film can be peeled off from the covering film, exposing the perforations in the covering film. Then, depending on the development, the medication can be injected into the corresponding area of ​​the skin using a syringe through the perforations. Alternatively, depending on the development, a pen can be used to draw marks on the skin through the perforations. Finally, the covering film can be peeled off the skin, and the pen marks left through the perforations can be connected to draw the specific area of ​​sweating on the skin.

[0024] If the through-hole function is not used, the sealing film is normally placed on top of the cover film, and the sealing film blocks the through-hole, thereby preventing the developing reaction layer from coming into contact with the outside air through the through-hole.

[0025] The through-holes are located between the grid gaps, or between the gaps of multiple scattered points. When the syringe is used for puncture, the developing reaction layer does not obstruct the needle puncture, and the needle tip will not puncture the developing reaction layer and bring the substances in the developing reaction layer into the body.

[0026] Preferably, as an improvement, the entire developing reaction layer is grid-like or dotted (not just the solid iodine layer is grid-like or dotted); an adhesive layer is provided on the cover film, and the adhesive layer and the developing reaction layer are alternately arranged; the adhesive layer is located between the grid gaps, or the adhesive layer is located between the gaps of multiple dots.

[0027] Therefore, the adhesive layer is located between the grid gaps, or between the gaps of multiple scattered points. In this way, the adhesive layer and the developing reaction layer are staggered, with the adhesive layer surrounding the developing reaction layer. This helps to increase the contact area between the adhesive layer and the skin, and improve the adhesion of the cover film.

[0028] Preferably, as an improvement, the solid iodine is solid iodine tincture or solid potassium iodide.

[0029] Preferably, as an improvement, the starch layer is a water-soluble starch layer or a water-soluble starch film. Attached Figure Description

[0040] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: cover film 1, developing reaction layer 2, solid iodine layer 21, starch layer 22, protective film 3, adhesive layer 4, through hole 5, and sealing film 6.

[0041] Example 1 The basics are as follows: Figures 1-2 The device shown is a tracing device for axillary apocrine glands, comprising a cover film 1, a developing reaction layer 2, and a protective film 3. In this embodiment, the cover film 1 is made of a transparent material, allowing the developing reaction layer 2 to be observed to undergo color-changing development. The cover film 1 is specifically a plastic film or a paper film, and the protective film 3 can also be a plastic film or a paper film (such as release paper). The developing reaction layer 2 is located between the cover film 1 and the protective film 3, and is fixed to the cover film 1 by adhesive bonding. The developing reaction layer 2 contains solid iodine and starch; specifically, it can be a mixture of starch and solid iodine. The solid iodine can be solid iodine tincture or solid potassium iodide. The mass ratio of solid iodine to starch is approximately 1:1; however, in actual implementation, this ratio can be adjusted appropriately.

[0042] Combination Figure 1 and Figure 2As shown, the cover film 1 has an adhesive layer 4. The adhesive layer 4 surrounds the outside of the developing reaction layer 2, enclosing the developing reaction layer 2. One side of the adhesive layer 4 is adhered to the cover film 1, and the other side of the adhesive layer 4 is adhered to the protective film 3. In different embodiments, the developing reaction layer 2 can be square, circular, or irregularly shaped, and the cover film 1 and the protective film 3 can also be square, circular, or irregularly shaped.

[0043] In this embodiment, the thickness of the developing reaction layer can be 1-2 mm. In different implementations, other thicknesses can be set according to actual conditions.

[0044] Thus, the developing reaction layer 2 is bonded and fixed on the cover film 1, and the protective film 3 covers the developing reaction layer 2. The developing reaction layer 2 is held in place by the cover film 1 and the protective film 3. In this way, when not in use, the cover film 1 and the protective film 3 protect the developing reaction layer 2, preventing it from absorbing moisture from the air and becoming ineffective, thereby improving the storage life of the developing reaction layer 2.

[0045] In use, the protective film 3 on the developing reaction layer 2 is peeled off, exposing the developing reaction layer 2 on the covering film 1. The covering film 1 is then applied to the armpit, and the adhesive layer 4 adheres to the skin, ensuring a stable bond. At this point, the developing reaction layer 2 is in contact with the armpit skin. When sweating occurs, the solid iodine and starch in the developing reaction layer 2 react with the sweat, causing a color change and thus developing the apocrine glands. The distribution area of ​​the apocrine glands is determined based on the developed area. Furthermore, after development is complete, the covering film is removed from the skin, leaving a developmental mark that can be used to further reference the distribution area of ​​the apocrine glands for disease treatment.

[0046] In this embodiment, since the covering film 1 covers the skin under the armpit, the covering film 1 can effectively lock in sweat, prevent sweat evaporation, ensure that the iodine and starch reaction has sufficient moisture, shorten the reaction time, improve the imaging effect, and reduce the error in determining the distribution range of apocrine glands.

[0047] Example 2 This embodiment further defines the scope of Embodiment 1, and combines it with... Figure 3 As shown, the developing reaction layer in this embodiment is specifically configured in layers. The specific developing reaction layer 2 includes a solid iodine layer 21 and a starch layer 22 bonded together. Thus, solid iodine forms a layer 21 on its own, and starch forms a layer 22 on its own. The solid iodine layer 21 and the starch layer 22 are bonded together.

[0048] When using, peel off the protective film 3, and then attach the covering film 1 to the armpit. After the solid iodine layer 21 and the starch layer 22 absorb sweat, they fuse together and react to produce color change and development.

[0049] The upper and lower positional relationship between the solid iodine layer 21 and the starch layer 22 is not limited. However, it is preferable to place the starch layer 22 above the solid iodine layer 21 (on the side of the solid iodine layer 21 away from the covering film 1). In this way, the solid iodine layer 21 is located between the starch layer 22 and the covering film 1, the solid iodine layer 21 has less contact with the outside air, and the starch layer 22 can reduce the volatilization of iodine in the solid iodine layer 21, thus ensuring the effectiveness of the solid iodine layer 21.

[0050] In specific production implementation, the solid iodine layer 21 in this embodiment can be a layer structure formed after the iodine solution applied to the covering film 1 dries; or the solid iodine layer 21 can be a layered structure formed by first applying iodine solution to non-woven fabric (at this time, there is no non-woven fabric as the skeleton of the solid iodine layer 21), and then the solid iodine layer 21 is adhered to the covering film 1.

[0051] The starch layer 22 can be a water-soluble starch film made of starch, which covers the solid iodine layer 21. Alternatively, starch can be directly coated onto the solid iodine layer 21 to form a starch layer on the solid iodine layer 21.

[0052] Example 3 Combination Figure 4 As shown, this embodiment is limited to embodiment 1. In this embodiment, the developing reaction layer 2 is grid-shaped. Specifically, the developing reaction layer 2 includes multiple horizontal strips and multiple vertical strips. The multiple horizontal strips and multiple vertical strips are arranged to intersect each other and coated on the cover film 1 to form a grid shape.

[0053] Alternatively, the developing reaction material is applied to a mesh-like nonwoven fabric. Since the nonwoven fabric is mesh-like, the developing reaction layer 2 is also formed after applying the developing material (starch and solid iodine). Then, the developing reaction layer 2 is bonded to the cover film 1.

[0054] In this way, the developing reaction layer 2 has multiple grids, each with a relatively fixed width or a relatively fixed distance between two adjacent grids. This allows for easy measurement of the distance in the developing area by visually observing the number of grids corresponding to the developing area.

[0055] Of course, this embodiment can be further limited based on Embodiment 2, in which case at least one solid iodine layer 21 in the developing reaction layer 2 is mesh-shaped (the starch layer 22 can also be designed as a mesh). The mesh-shaped solid iodine layer 21 can be formed by directly coating solid iodine into a mesh shape, or by coating solid iodine onto a mesh-shaped nonwoven fabric, thereby forming a mesh-shaped solid iodine layer. In this embodiment, the width of each mesh can be 1-3 mm, and the mesh can be a square mesh. Of course, in specific implementation, the width of the mesh can be set according to the actual situation.

[0056] Because the solid iodine layer 21 is in contact with the cover film 1, while the starch layer 22 is not in direct contact with the cover film 1, the solid iodine layer 21 is set in a grid shape, which makes it easy to visually observe the number of grids corresponding to the developing area through the transparent cover film 1, thereby facilitating the measurement of the distance to the developing area.

[0057] Example 4 This embodiment further defines the feature of embodiment 3. In this embodiment, the cover film 1 is provided with multiple grooves, and at least the solid iodine layer 21 sinks into the grooves when the developing reaction layer 2 is layered. The shape of the grooves is the same as the grid shape of the grid-like solid iodine layer 21, that is, the grooves are also grid-shaped, so that the solid iodine layer 21 can sink into the grooves better.

[0058] Combination Figure 5 As shown, in a more preferred embodiment, not only does the solid iodine layer 21 sink into the groove, but the starch layer 22 also sinks into the groove in a grid pattern (the grid pattern of the starch layer 22 coincides with the grid pattern of the solid iodine layer 21).

[0059] As a result, the solid iodine layer 21 sinks into the groove, thereby increasing the contact area between the developing reaction layer 2 and the covering film 1, improving the fixation of the developing reaction layer 2 and the covering film 1, and making it less likely for the developing reaction layer 2 and the covering film 1 to shift relative to each other. At the same time, the groove can cover the solid iodine layer 21. The solid iodine layer 21 is wrapped by the inner wall of the groove and the starch layer 22, thereby reducing the contact between the solid iodine layer 21 and the outside air, which helps to reduce the volatilization of iodine and increase the accuracy of the experiment.

[0060] Example 5 Combination Figure 6 As shown, the difference between this embodiment and embodiment 4 is that in this embodiment, only the solid iodine layer 21 is mesh-shaped and sinks into the groove, while the starch layer 22 is not mesh-shaped. The starch layer 22 is located above the film and the solid iodine layer 21 and covers the entire film and the solid iodine layer 21.

[0061] Example 6 This embodiment is based on embodiment 1 or embodiment 2 with some limitations.

[0062] When defining Example 1, in conjunction with Figure 7 As shown, the developing reaction layer 2 is in the form of scattered dots, that is, the developing reaction material is applied to the cover film 1 in a dotted pattern, and the developing reaction layer 2 is composed of multiple protruding scattered dots.

[0063] When defining Example 2, the developing reaction layer 2 is also dotted, except that the developing reaction layer 2 is divided into a starch layer 22 and a solid iodine layer 21.

[0064] For scattered points, the radius can be 1-2mm, specifically 1.5mm. Of course, in actual implementation, the radius can be set according to the actual situation.

[0065] In this way, the developing reaction layer 2 includes multiple scattered points, and the distance between adjacent scattered points is relatively fixed. By visually observing the number of scattered points corresponding to the developing area, it is easy to measure the distance of the developing area.

[0066] Of course, in this embodiment, multiple grooves can also be provided on the cover film 1. In this case, the grooves are circular, and the developing reaction layer 2 fills the grooves. The function of these grooves is the same as that of the grooves in embodiment 4, and will not be described in detail in this embodiment.

[0067] Example 7 In this embodiment, when the entire developing reaction layer 2 is grid-like or scattered, regardless of whether the developing reaction layer 2 is a single piece or consists of a starch layer 22 and a solid iodine layer 21, the adhesive layer 4 on the cover film 1 is combined with... Figure 8 As shown, the adhesive layer 4 and the developing reaction layer 2 are staggered. That is, when the developing reaction layer 2 is grid-like, the adhesive layer 4 is located within the grid (within the grid gaps), and when the developing reaction layer 2 is dotted, the adhesive layer 4 is located between the gaps of multiple dots.

[0068] Therefore, the adhesive layer 4 is located between the grid gaps, or between the gaps of multiple scattered points. The adhesive layer 4 and the developing reaction layer 2 are staggered, and the developing reaction layer 2 is surrounded by the adhesive layer 4. Figure 8 Specifically, the starch layer 22 and the adhesive layer 4 are alternately arranged, which makes it easier for the adhesive layer 4 to contact the skin and improves the adhesion of the covering film 1.

[0069] Example 8 Combination Figures 9-10 As shown, when the entire developing reaction layer 2 is grid-like or scattered, regardless of whether the developing reaction layer 2 is a single piece or divided into a starch layer 22 and a solid iodine layer 21, the cover film 1 is provided with multiple through holes 5.

[0070] When the developing reaction layer 2 is grid-like, the through holes 5 are located between the grid gaps, with each through hole 5 corresponding to a pore of one grid. Of course, in other embodiments, the through holes 5 and the grids may not correspond one-to-one. In this case, not every grid has a through hole 5; instead, a through hole 5 can be set in one grid every few grids.

[0071] Alternatively, when the developing reaction layer 2 is dotted, the through-hole 5 is located between the gaps of multiple dots. Of course, the through-hole 5 may not be located between every two adjacent dots; it can be placed every few dots between adjacent dots.

[0072] A sealing film 6 is placed on the side of the cover film 1 away from the developing reaction layer 2. The sealing film is a transparent plastic film or release paper, and the sealing film 6 is bonded to the cover film 1.

[0073] Therefore, before use, the sealing membrane 6 is placed on the covering membrane 1 to seal the through hole 5, thereby preventing external gas from entering between the covering membrane 1 and the protective membrane 3 through the through hole 5.

[0074] In use, after the developing reaction layer 2 has developed, the sealing film 6 can be peeled off from the covering film 1, exposing the through-hole 5 on the covering film 1. Then, depending on the development, the therapeutic drug can be injected into the corresponding area of ​​the skin through the through-hole 5 using a syringe. Alternatively, depending on the development, a pen can be used to draw marks on the skin through the through-hole 5. Finally, the covering film 1 can be peeled off from the skin, and the pen marks left through the through-hole 5 can be connected to draw the specific area of ​​sweating on the skin.

[0075] In this embodiment, the through hole 5 is located between the grid gaps, or between the gaps of multiple scattered points. When the syringe is used for puncture, the developing reaction layer 2 will not block the needle tip from puncturing, and the needle tip will not puncture the developing reaction layer 2 and bring the substances in the developing reaction layer 2 into the body.

[0076] In the above embodiments, iodine can also be replaced with potassium iodide.

[0077] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
