Description

Technical Field

[0001] This invention relates to the technical field of expanders, and more particularly to an expander protection device and its processing method. Background Technology

[0002] In medical procedures, expanders are widely used in various surgical or therapeutic operations to open up specific human tissues or cavities, facilitating subsequent diagnosis and treatment. However, existing expanders often lack effective protective measures during use, making them susceptible to external impacts, friction, and other factors. This can damage the expander itself, shorten its lifespan, and increase medical costs. Furthermore, if the skin surface is damaged, it can lead to risks such as infection and expander leakage, threatening the patient's health. Therefore, there is an urgent need for a device that can properly protect expanders. Summary of the Invention

[0003] This invention aims to at least partially address one of the problems in related technologies. Therefore, one objective of this invention is to provide an expander protection device that provides comprehensive protection for the expander, effectively improving the safety and stability of its use.

[0004] An expander protection device, the expander protection device comprising: An elastic pad, wherein the elastic pad has a receiving groove for covering the expander; The fabric is sewn to form a wrapping cavity with an opening, the shape of which is adapted to the shape of the elastic pad, the elastic pad is disposed inside the wrapping cavity, and the receiving groove is provided corresponding to the opening; A securing strap is attached to the fabric and is used to secure the garment to the user.

[0005] Furthermore, the material of the elastic cushion is natural latex, silicone, polyurethane elastomer, or thermoplastic elastomer.

[0006] Specifically, the materials available for the elastic pads include natural latex, silicone, polyurethane elastomers, or thermoplastic elastomers. These materials all possess a certain degree of elasticity and flexibility, meeting the functional requirements of a close fit to the expander and cushioning external forces. The differences in the properties of different materials provide diverse options for products in various application scenarios.

[0007] Furthermore, the fixing strap is made of nylon, polyester fiber, or spandex.

[0008] Specifically, the securing strap can be made of nylon, polyester, or spandex. Nylon is strong and abrasion-resistant; polyester is durable and wrinkle-resistant; and spandex is elastic. These properties allow the securing strap to better adapt to different usage environments and user needs, ensuring both a secure and comfortable fit when securing protective devices.

[0009] Furthermore, the material of the fabric is non-woven fabric, gauze, ice silk fabric, cotton fabric, or a blend of polyester fiber and cotton.

[0010] Specifically, the fabric material can be non-woven fabric, gauze, ice silk fabric, cotton fabric, or a blend of polyester and cotton. Each fabric has its unique properties: non-woven fabric is low-cost and has decent breathability; gauze has strong water absorption; ice silk fabric has excellent breathability and moisture absorption; cotton fabric is soft and comfortable; and blended fabrics combine multiple advantages. This provides a basis for selecting appropriate fabrics according to different medical scenarios and patient needs, expanding the applicability of the product.

[0011] Furthermore, the surface of the fabric is also coated with a nano-coating.

[0012] Specifically, the fabric surface undergoes a special treatment, being coated with a self-cleaning nano-coating. This coating utilizes the superhydrophobic properties of nanomaterials, making it difficult for stains, blood, and other liquids to adhere to the fabric surface. Even if a small amount of stains occurs, they can roll off with slight shaking or airflow, keeping the fabric clean for a long time and reducing a breeding ground for bacteria.

[0013] Furthermore, the fabric has a replacement opening on one side surface opposite the opening, and the fabric is also provided with a zipper connected to open or close the replacement opening.

[0014] Specifically, the interchangeable opening and zipper design facilitates the replacement of elastic pads or other internal components, improving the ease of maintenance and reusability of the device. In particular, when the elastic pads are damaged or require cleaning, the entire device can be replaced without disassembling it, reducing operating costs and operational difficulties, and providing convenience for the long-term use and management of the product.

[0015] Furthermore, the expander protection device also includes a display and control device and a pressure sensor. The pressure sensor is disposed on the wall of the receiving groove, and the display and control device is connected to the elastic pad and electrically connected to the pressure sensor. The display and control device includes a controller and a flexible display screen.

[0016] Specifically, a display and control device and a pressure sensor are introduced. The pressure sensor, placed on the wall of the receiving tank, monitors the force applied to the expander. The display and control device (including a controller and a flexible display screen) is electrically connected to it and can display pressure information in real time. This design enables the monitoring of the expander's operating status, helping medical staff to understand the expander's working condition in a timely manner, avoiding expander damage or medical accidents caused by abnormal pressure, and improving the intelligence and safety of the device.

[0017] Furthermore, the fabric is also provided with a clearance opening, which is provided in relation to the display and control device. When the elastic pad is installed in the wrapping cavity, the display and control device is correspondingly located in the clearance opening.

[0018] And / or, the expander protection device further includes a plurality of heating elements and a plurality of cooling elements, wherein the plurality of heating elements and the plurality of cooling elements are disposed on the elastic pad and spaced apart along the edge of the receiving groove, and the plurality of heating elements and the plurality of cooling elements are electrically connected to the controller; And / or, the expander protection device further includes a piezoelectric material sheet disposed on the side surface of the fixing band facing the elastic pad, the piezoelectric material sheet being electrically connected to the controller.

[0019] Specifically, clearance openings are provided on the fabric to ensure that the display and control device can be accurately positioned after the elastic pad is installed, so that the display and control function can be realized smoothly.

[0020] Specifically, heating and cooling elements are spaced apart along the edge of the receiving slot and electrically connected to a controller. This allows for temperature adjustment around the expander, enabling heating or cooling of the contact area during wear, improving comfort and safety. On the other hand, piezoelectric material sheets are placed on the fixing band and electrically connected to the controller. When the user (medical staff or patient) experiences minor stretching or bending deformation of the fixing band during activity, the piezoelectric material converts mechanical energy into electrical energy and stores it. The piezoelectric material sheets collect this mechanical energy and convert it back into electrical energy to power the device. The collected electrical energy can be used to power the microelectronic components in the intelligent sensing and monitoring module and the temperature regulation module, reducing reliance on external batteries, extending the device's battery life, enhancing its energy self-sufficiency and environmental adaptability, and further improving the product's functional diversity and innovation.

[0021] Furthermore, the expander protection device also includes a water reservoir valve protection assembly and a connecting strap. The water reservoir valve protection assembly includes a rubber ring and double-sided adhesive. One end of the connecting strap is connected to the fixing strap, and the other end is connected to the outer surface of the rubber ring. The double-sided adhesive is connected to one end face of the rubber ring.

[0022] In medical procedures, if the expander involves a water reservoir, its valve area is relatively fragile and easily damaged by contamination, impact, etc. The rubber ring in the water reservoir valve protection component can fit tightly around the valve, providing initial protection and sealing, reducing the risk of skin necrosis and leakage on the valve surface caused by impact and external factors; the double-sided adhesive can use its stickiness to adhere the rubber ring to the user's skin, thus fixing the valve, and is convenient and easy to use.

[0023] The present invention also proposes a method for manufacturing an expander protection device, for producing the expander protection device as described above, using elastic pads, fabric, and fixing straps. The method for manufacturing the expander protection device includes the following steps: Measure the size of the user's expander; Based on the measured expander size, the elastic pad is cut to the target size, and the receiving groove is provided in the elastic pad, the volume of the receiving groove being adapted to the expander size; According to the size of the elastic pad, the fabric is cut and sewn, and an opening is made in the sewn fabric to form the enclosing cavity, the volume of which is adapted to the size of the elastic pad; Connect the fixing strap to the fabric. Compared with the prior art, the above-mentioned technical solution provided in this application has the following advantages: The expander protection device of this application includes an elastic pad, a fabric, and a fixing strap. The elastic pad is precisely cut according to the actual size of the expander and has a receiving groove inside. The shape of this receiving groove is adapted to the shape of the expander, which can tightly and alignedly cover the user's expander, effectively preventing the expander from shifting and providing stable support and protection. In addition, the use of flexible materials can reduce impact and achieve the effect of protecting the expander. The fabric is finely sewn according to the size of the elastic pad to form a wrapped cavity with an opening. This wrapped cavity is specifically used to cover the elastic pad, and the position of the opening corresponds to the receiving groove on the elastic pad, ensuring that the expander can enter and exit smoothly. The fabric has waterproof and dustproof effects, making the protection device suitable for humid or dusty environments. The fixing strap is firmly connected to the fabric. Its design purpose is to facilitate fixing with the user and ensure that the protection device will not accidentally slip or shift during use.

[0024] The expander protection device of the present invention has a simple structure and reasonable design. Through the coordinated use of elastic pads, fabric and fixing straps, it provides all-round protection for the expander, effectively improving the safety and stability of the expander during use.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Example 1 like Figure 1 - Figure 3 As shown, the expander protection device 1 provided in this application includes: The elastic pad 10 has a receiving groove 11 for covering the expander. Fabric 30 is sewn to form a wrapping cavity 33 with an opening 31. The shape of the wrapping cavity 33 is adapted to the shape of the elastic pad 10. The elastic pad 10 is disposed in the wrapping cavity 33, and the receiving groove 11 is correspondingly disposed to the opening 31. The fixing strap 40 is attached to the fabric 30 and is used to secure the user.

[0033] In this embodiment, the elastic pad 10 is made of natural latex, the fabric 30 is made of ice silk fabric 30, and the fixing strap 40 is an elastic band. Natural latex has good elasticity and flexibility, which can not only fit tightly to the expander and buffer external impact, but also prevent scratching damage to the surface of the expander. Ice silk fabric 30, with its good breathability and moisture absorption, brings a more comfortable user experience, and can effectively reduce skin discomfort even when worn for a long time. The elastic band, as the fixing strap 40, not only allows users to adjust it according to their own needs and ensures the stability of the device, but also adapts to users of different body types to a certain extent, improving the applicability and convenience of the device.

[0034] Optionally, the expander protection device can be designed as multiple modules. The elastic pad 10 serves as the core load-bearing module, directly contacting the expander; the fabric 30 serves as the protective isolation module; and the fixing strap 40 serves as the fixing support module. The modules are combined together using convenient snap-fit, slot, or magnetic connection methods. When a module is damaged or needs replacement, there is no need to replace the entire device; simply disassemble the corresponding module and replace it with a spare, greatly reducing operating costs and improving the device's versatility and flexibility.

[0035] Optionally, when there are two fixing straps 40, the connection and fixing methods for the two fixing straps 40 can be snap-fit ​​connection, slot connection, magnetic connection, etc. Snap-fit ​​connection: Snap-fits made of plastic or metal are used, and their structure includes a male and a female snap-fit. The male snap-fit ​​has a protruding head, and the female snap-fit ​​has a corresponding slot. When the male and female snap-fits are engaged, the head can be tightly embedded in the slot, achieving a secure connection between the two fixing straps 40. Slot connection: Slots and pins are provided on the edges of the two fixing straps 40. The slots adopt a rectangular or circular hole structure, and the pins match the slots. When it is necessary to connect the two fixing straps 40, the pin is inserted into the slot, and the module is fixed through friction and mechanical action. Magnetic connection: Magnets made of strong magnetic materials such as neodymium iron boron are used, and are respectively installed on the two fixing straps 40. The polarity of the magnets is designed to attract each other. When the two fixing straps 40 are close together, the magnets will automatically attract each other, achieving a quick connection. To ensure the stability of the magnetic connection, some positioning protrusions or grooves can be set at the connection points of the two fixing straps 40 so that the two fixing straps 40 can be accurately aligned when connected.

[0036] Example 2 like Figure 1 - Figure 3 As shown, the expander protection device 1 provided in this application includes: The elastic pad 10 has a receiving groove 11 for covering the expander. Fabric 30 is sewn to form a wrapping cavity 33 with an opening 31. The shape of the wrapping cavity 33 is adapted to the shape of the elastic pad 10. The elastic pad 10 is disposed in the wrapping cavity 33, and the receiving groove 11 is correspondingly disposed to the opening 31. The fixing strap 40 is attached to the fabric 30 and is used to secure the user.

[0037] In this embodiment, the elastic pad 10 is made of silicone, the fabric 30 is made of non-woven fabric, and the fixing strap 40 is made of polyester fiber. Silicone has good elasticity and softness, effectively protecting the expander from impact and damage during use. Non-woven fabric has good breathability and a certain degree of abrasion resistance, ensuring air circulation within the enclosure cavity 33 and preventing moisture and bacterial growth. Polyester fiber has high strength and abrasion resistance, ensuring the stability and durability of the fixing strap 40, making the protective device more reliable.

[0038] Example 3 like Figure 1 - Figure 3 As shown, the expander protection device 1 provided in this application includes: The elastic pad 10 has a receiving groove 11 for covering the expander. Fabric 30 is sewn to form a wrapping cavity 33 with an opening 31. The shape of the wrapping cavity 33 is adapted to the shape of the elastic pad 10. The elastic pad 10 is disposed in the wrapping cavity 33, and the receiving groove 11 is correspondingly disposed to the opening 31. The fixing strap 40 is attached to the fabric 30 and is used to secure the user.

[0039] In this embodiment, the elastic pad 10 is made of polyurethane elastomer, the fabric 30 is made of a polyester fiber and cotton blend, and the fixing strap 40 is made of spandex. Polyurethane elastomer has excellent abrasion resistance, tear resistance, and resilience, effectively improving the overall performance of the expander protection device. The polyester fiber and cotton blend combines the high strength of polyester fiber with the comfort of cotton, making the wrapping cavity 33 both durable and skin-friendly. Spandex, as the material of the fixing strap 40, gives it good elasticity and stretchability, facilitating fixation to the user without causing excessive restriction.

[0040] Example 4 like Figure 4 , Figure 5 As shown, the expander protection device 1 provided in this application includes: The elastic pad 10 has a receiving groove 11 for covering the expander. Fabric 30 is sewn to form a wrapping cavity 33 with an opening 31. The shape of the wrapping cavity 33 is adapted to the shape of the elastic pad 10. The elastic pad 10 is disposed in the wrapping cavity 33, and the receiving groove 11 is correspondingly disposed to the opening 31. The fixing strap 40 is attached to the fabric 30 and is used to secure the user.

[0041] In this embodiment, the elastic cushion 10 is made of natural latex, the fabric 30 is made of ice silk fabric 30, and the fixing strap 40 is an elastic band.

[0042] Furthermore, the surface of fabric 30 is also coated with a nano-coating.

[0043] Specifically, the surface of fabric 30 is specially treated by coating it with a self-cleaning nano-coating. This coating utilizes the superhydrophobic properties of nanomaterials to make it difficult for stains, blood, and other liquids to adhere to the surface of fabric 30. Even if a small amount of stains are present, they can roll off with slight shaking or airflow, keeping fabric 30 clean for a long time and reducing the breeding ground for bacteria.

[0044] Optionally, a nano-self-cleaning coating based on titanium dioxide (TiO2) can be used. This coating has superhydrophilicity and photocatalytic activity, and under ultraviolet irradiation, it can decompose organic matter adhering to the surface of fabric 30 into carbon dioxide and water, thereby achieving a self-cleaning effect.

[0045] Optionally, an antibacterial agent, such as a silver ion antibacterial agent, can be mixed into the elastic pad 10 and the fabric 30. Silver ions can be continuously released, effectively inhibiting the growth and reproduction of microorganisms such as bacteria and fungi, further reducing the risk of infection, and providing more reliable protection for patients when wearing and using the expander protection device.

[0046] Furthermore, in addition to silver ion antibacterial agents, chitosan antibacterial agents can also be used. Chitosan is a natural polysaccharide compound with good biocompatibility and antibacterial properties.

[0047] Furthermore, a replacement opening is provided on the side of the fabric 30 opposite to the opening 31, and the fabric 30 is also equipped with a zipper 37, which is connected to open or close the replacement opening. The replacement opening facilitates the replacement and cleaning of the elastic pad 10, improving the practicality and hygiene of the expander protection device. As a common connector, the zipper 37 is easy and quick to operate, effectively ensuring the sealing of the replacement opening and preventing external bacteria or contaminants from entering the expander protection device through the replacement opening. At the same time, the zipper 37 is also durable and can meet the requirements of long-term use.

[0048] Furthermore, the expander protection device also includes a display and control device 50 and a pressure sensor 60. The pressure sensor 60 is located on the wall of the receiving groove 11. The display and control device 50 is connected to the elastic pad 10 and electrically connected to the pressure sensor 60. The display and control device 50 includes a controller 51 and a flexible display screen 53.

[0049] Specifically, miniature pressure sensors 60 are embedded inside or close to the surface of the elastic pad 10. These sensors can detect changes in pressure experienced by the expander during use in real time. Once the pressure exceeds the normal operating range, such as in the event of an accidental impact or excessive tissue compression of the expander, the sensors immediately send a signal to the connected microcontroller 51. The microcontroller 51 is equipped with Bluetooth or other wireless transmission modules, which can transmit abnormal pressure information in real time to a smart terminal (such as a wristband, mobile app, etc.) worn by medical personnel, issuing an alarm to remind them to adjust their operation in time and avoid damage to the expander and potential harm to the patient.

[0050] Optionally, the display and control device 50 includes a controller 51 and a flexible display screen 53. Using flexible transparent display screen technology, it is attached to a specific area on the surface of the fabric 30. The display screen is connected to the micro controller 51 and can display the pressure data and temperature information of the expander in real time. It can even be connected to the hospital information system to display the patient's basic medical information, such as allergy history and medications currently in use. This allows medical staff to fully grasp key data during operation without having to look away, providing strong support for precision medicine.

[0051] Furthermore, the fabric 30 is also provided with a clearance opening 39, which corresponds to the display and control device 50. When the elastic soft pad 10 is installed in the wrapping cavity 33, the display and control device 50 is correspondingly located in the clearance opening 39.

[0052] Specifically, the design of the clearance opening 39 not only ensures that the display and control device 50 can be smoothly exposed on the fabric 30, but also avoids unnecessary friction or compression of the display and control device 50 during use, thereby ensuring its normal operation and service life. In addition, the shape and size of the clearance opening 39 can be customized according to the specific dimensions of the display and control device 50 to ensure optimal installation effect and ease of operation.

[0053] Optionally, miniature visual labels can be printed or embedded on the outer layer of the fabric 30. These labels can include the user's name, surgery date and time, precautions, or a diagram showing the correct placement and orientation of the expander. For inexperienced medical personnel, these labels allow them to quickly refer to the labels to ensure accurate positioning of the expander, reducing time delays and potential risks caused by operational errors.

[0054] And / or, the expander protection device also includes a plurality of heating elements 70 and a plurality of cooling elements 80, all of which are disposed on the elastic pad 10 and spaced apart along the edge of the groove of the receiving groove 11, and all of which are electrically connected to the controller 51. And / or, the expander protection device also includes a piezoelectric material sheet 90, which is disposed on the side surface of the fixing band 40 facing the elastic pad 10, and the piezoelectric material sheet 90 is electrically connected to the controller 51.

[0055] Specifically, ultra-thin flexible heating / cooling elements 80, such as a film based on the thermoelectric effect, are laid inside the elastic pad 10 or within the fabric 30 interlayer. These elements are connected to a small temperature control module, which automatically adjusts the heating or cooling power according to a preset temperature range (ideally close to human body temperature). By adjusting the temperature of the expander protection device, the environment around the expander can be kept suitable, avoiding stimulation of human tissue due to excessively low or high temperatures, improving wearing comfort and safety, and reducing the probability of adverse reactions after wearing.

[0056] Optionally, the thermoelectric thin film can be made of bismuth telluride (Bi2Te3)-based thermoelectric materials. This material has high thermoelectric conversion efficiency, enabling rapid heating or cooling when an electric current is applied. The thin film employs a multi-layer composite design, with the thermoelectric material in the middle layer and electrode and insulating layers on either side. The electrode layers are made of metallic materials, such as copper or silver, for conducting current; the insulating layers are made of ceramic or polymer materials to prevent current leakage. Furthermore, a temperature control module is included, employing a PID control algorithm-based temperature control chip. This chip can precisely control the temperature by adjusting the current of the heating / cooling element 80 based on a preset temperature value and real-time temperature data collected by a sensor. Simultaneously, the temperature control module can also integrate a temperature display function, showing the current temperature value in real-time via an LED or OLED display screen.

[0057] Specifically, a miniature piezoelectric material sheet 90 is integrated into the fixing band 40. When the user (medical staff or patient) causes slight stretching, bending, or other deformations to the fixing band 40 during activity, the piezoelectric material can convert mechanical energy into electrical energy and store it. The collected electrical energy can be used to power the microelectronic components in the intelligent sensing and monitoring module and the temperature regulation module, reducing reliance on external batteries and extending the device's battery life.

[0058] Optionally, a piezoelectric material sheet 90 made of lead zirconate titanate (PZT) piezoelectric ceramic material is selected. This material has a high piezoelectric coefficient and can generate a large amount of charge when subjected to external force. The piezoelectric material sheet 90 adopts a multi-layer stacked design to increase the output voltage and charge. At the same time, in order to improve the energy conversion efficiency, some microstructures, such as protrusions or grooves, can be formed on the surface of the piezoelectric material sheet 90 to enhance its ability to absorb and convert mechanical energy.

[0059] Furthermore, the expander protection device also includes a water bottle valve protection assembly 100 and a connecting strap 110. The water bottle valve protection assembly 100 includes a rubber ring 101 and double-sided adhesive 102. One end of the connecting strap 110 is connected to the fixing strap 40, and the other end is connected to the outer surface of the rubber ring 101. The double-sided adhesive 102 is connected to one end face of the rubber ring 101.

[0060] The expander protection device includes a water bottle valve protection assembly 100 and a connecting strap 110. The water bottle valve protection assembly 100 consists of a rubber ring 101 and double-sided adhesive 102. The rubber ring 101 has an opening, and the double-sided adhesive 102 facilitates adhesion to the skin. The main function of this assembly is to protect the water bottle valve, which may be affected by the expander. The connecting strap 110 connects to the fixing strap 40 at one end and to the outer surface of the rubber ring 101 at the other end. Its function is to connect the water bottle valve protection assembly 100 to the entire protection device, making all parts an integrated whole.

[0061] The rubber ring 101 in the water reservoir valve protection assembly 100 can tightly fit around the valve, providing initial protection and sealing, reducing the risk of necrosis and leakage of the valve surface due to impact and external factors, thus effectively protecting the water reservoir valve and ensuring the expander can operate normally during water injection operations. The connecting strap 110 connects the water reservoir valve protection assembly 100 to the fixing strap 40, making the entire expander protection device structure more complete. On the one hand, this connection method allows the water reservoir valve protection assembly 100 to be stably installed on the protection device, preventing it from shaking or falling off; on the other hand, it also facilitates the overall control and use of the protection device by medical personnel during operation, improving the ease of use of the device.

[0062] The rubber ring 101 can be made of silicone rubber, which has good temperature resistance, chemical stability, and sealing performance, maintaining stable performance in various medical environments. Alternatively, the rubber ring 101 can be made of hard sponge, which has excellent resilience and cushioning properties, allowing it to better conform to the skin around the valve, improving wearing comfort and sealing effect. The double-sided adhesive 102 uses medical-grade double-sided tape, with moderate adhesion, which can firmly attach the rubber ring 101 without causing irritation or damage to the user's skin.

[0063] The rubber ring 101 can be designed into a special shape that fits tightly with the valve of the water bottle, such as a ring with a lip structure. The lip can fit the valve surface better and enhance the sealing effect.

[0064] The connecting strap 110 can be made of high-strength polyester fiber, which has good wear resistance and tensile strength, ensuring that it will not easily break during use and stably connects the fixing strap 40 and the water bottle valve protection assembly 100. Alternatively, it can be made of elastic spandex, which can adapt to different stretching requirements to a certain extent, making the protection device more flexible in use.

[0065] The connecting strap 110 can be designed as a flat strap structure, which ensures connection strength while reducing pressure on the user and improving wearing comfort. Alternatively, it can be a chain-like structure with multiple connecting holes. By selecting different connecting holes, the length of the connecting strap 110 can be flexibly adjusted to adapt to different usage scenarios.

[0066] The present invention also proposes a method for processing an expander protection device 1, which includes the expander protection device. The specific structure of the expander protection device is as described in the above embodiments. Since the processing method of this expander protection device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0067] In the actual manufacturing process, firstly, according to the specifications and models of common expanders, various sizes of elastic pads 10 are prepared. Using high-precision molds or cutting equipment, they are cut to predetermined dimensions, and receiving grooves 11 are punched out using a special mold to ensure the precision and smoothness of the grooves. Next, medical-grade fabric 30, such as non-woven or cotton fabric 30, is selected and, after sterilization, sewn according to the shape and size of the elastic pads 10. An opening 31 is left during sewing, and the edges of the opening 31 are bound to prevent unraveling. Finally, fixing straps 40, such as webbing with Velcro, are sewn to appropriate positions on the fabric 30, usually on both sides or one end, to facilitate fixation around the user's body or limbs.

[0068] When using the device, medical staff first align the elastic pad 10 with the opening 31 of the covering cavity 33 of the fabric 30 and slowly push it in so that the fabric 30 completely covers the elastic pad 10. Then, they align the receiving groove 11 of the elastic pad 10 with the user's expander and wrap the elastic pad 10 around the expander to ensure a tight fit.
