Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insulin pump fixing application, in particular to an insulin pump fixing and protecting device. BACKGROUND

[0002] The insulin pump fixing and protecting device is a medical device used to assist the use of insulin pump. Its main function is to ensure that the insulin pump is firmly attached to the patient's body during use through a specific fixing method, preventing loosening or falling off due to movement or other external forces.

[0003] However, the existing insulin pump fixing and protecting device has certain defects in use. The existing insulin pump fixing and protecting device performs poorly in waterproofing. Patients need to remove the insulin pump when taking a bath or swimming, otherwise water may enter the device, causing damage to the device or affecting its normal operation. The existing insulin pump fixing and protecting device usually directly adheres the insulin pump to the skin, which may cause skin discomfort, allergy and other adverse reactions. In order to improve concealment, the existing insulin pump fixing and protecting device is mostly directly adhered to the skin, but has poor air permeability, and long-term wearing may cause skin sweating, dampness and increase the risk of skin infection. SUMMARY

[0004] In view of the problems in the prior art, the present application provides an insulin pump fixing and protecting device.

[0005] The technical scheme adopted by the present application to solve the technical problem is: the insulin pump fixing and protecting device comprises a sticking layer, a bottom film and a film covering. The sticking layer has adhesion on one side and is used to adhere to the skin, which can tightly adhere to the skin and provide a stable base for the entire device. The bottom film is fixed to the non-adhesive side of the sticking layer and serves as an intermediate connecting layer. The film covering is adhered to the side of the bottom film away from the sticking layer and is used to adhere and wrap the insulin pump, so that the insulin pump is fixed to one side of the bottom film. The film covering cooperates with the bottom film to form a waterproof sealing patch, effectively blocking the intrusion of external moisture and protecting the insulin pump from a humid environment.

[0006] Preferably, the sticking layer has a breathable patch in the middle, which has breathable holes to provide air permeability for the skin, avoiding skin heat, sweating or discomfort caused by long-term wearing of the device.

[0007] Preferably, the bottom film is fixed to the breathable patch of the sticking layer, which can tightly combine the bottom film with the breathable part of the sticking layer, ensuring the stability and functionality of the entire device.

[0008] Preferably, a mesh-structured pad is provided between the bottom film and the breathable patch, and the pad has interconnected air vents, which can further enhance the breathability and spatial isolation effect of the device. The mesh structure of the pad creates a certain space between the bottom film and the breathable patch, preventing them from being directly and tightly adhered, thereby providing more channels for gas circulation.

[0009] Preferably, the covering includes an edge seal, a support frame, and an elastic membrane. The edge seal has a U-shaped structure, and the side of the edge seal closest to the base film is adhesive. This adhesiveness tightly adheres to the base film, forming a sealed boundary to prevent moisture and external contaminants from seeping in from the edge, ensuring the waterproof performance of the entire device. The support frame also has a U-shaped structure and is fixed inside the edge seal, providing support for the elastic membrane and ensuring that the elastic membrane maintains its shape and tension. The elastic membrane is fixed to the support frame, allowing it to tightly conform to the shape of the device when wrapping the insulin pump. The covering not only tightly adheres to the base film, creating a good seal, but also, through the synergistic effect of the support frame and the elastic membrane, ensures the stability and safety of the insulin pump during use.

[0010] Preferably, the elastic membrane, supported by the support frame, protrudes to the side away from the base membrane, forming a cavity with a certain space. This protruding structure provides a suitable housing space for the insulin pump, preventing excessive compression when the pump is encased. The elastic membrane is transparent and elastic; its transparent design allows medical staff and patients to directly observe the working status of the insulin pump, including important information such as the device's display screen and indicator lights.

[0011] Preferably, an adhesive layer for securing the insulin pump is fixed to the center of the base membrane on the side away from the adhesive layer. The position of the adhesive layer corresponds to the position of the elastic membrane. By setting the adhesive layer, which is located in the center of the base membrane, it is specifically used to secure the insulin pump. Its adhesive design ensures that the insulin pump adheres firmly to the base membrane, preventing the device from shifting or falling off during use. The side of the adhesive layer away from the base membrane is adhesive and has a protective layer applied before use to prevent the adhesive layer from sticking to the elastic membrane.

[0012] Preferably, a sealing strip is attached to the end of the base film near the overlay for wrapping around the insulin pump tubing connection. The sealing strip is adhesive on the side near the base film, and its design is an important supplement to the sealing and reinforcement of the insulin pump tubing interface. After sealing the insulin pump body with the base film and overlay, the sealing strip is peeled off and wrapped around the insulin pump tubing interface. The adhesive side of the sealing strip near the base film allows it to adhere tightly around the tubing interface, forming an additional sealing layer.

[0013] Preferably, the adhesive layer at both ends is connected with an adhesive tape with adhesion, which can provide additional adhesive area and adhesion, thereby enhancing the fixation firmness of the whole device with the skin, and ensuring that the device will not be easily displaced or detached during the patient's daily activities or movements. The adhesive tape is arranged upwardly inclined, which can provide upward tension, so that the device can better disperse the stress when subjected to external force, avoiding loosening or falling off due to excessive local stress.

[0014] The beneficial effects of the present application are:

[0015] (1) In the present application, the insulin pump fixing and protecting device is provided with a bottom film and a film cover, after the insulin pump is adhered to the adhesive layer of the bottom film, the film cover is pasted back to the bottom film, the edge of the film cover is tightly pasted with the bottom film, and the elastic film can wrap and press the insulin pump to seal the insulin pump. By the cooperation of the bottom film and the film cover, water can be effectively prevented from entering, so that the insulin pump can be well protected even when the patient is taking a bath or swimming, and damage or influence on the normal work of the device caused by water contact can be avoided. The patient does not need to take off the insulin pump before taking a bath or swimming, which reduces the trouble of operation, and also reduces the irritation and damage to the skin caused by frequent taking off and wearing of the insulin pump, thereby improving the convenience of the patient wearing the insulin pump. In addition, the good sealing property of the device can also prevent dust and bacteria from entering, which helps to keep the insulin pump clean and sanitary, prolongs the service life, and improves the safety of use.

[0016] (2) In the present application, the sealing effect of the film cover of the insulin pump fixing and protecting device with the bottom film is higher than that of directly combining with the skin. The bottom film serves as a relatively flat and stable base, which can better cooperate with the film cover to form a more tightly sealed structure. At the same time, the adhesive layer separates the insulin pump from the human skin, avoiding the discomfort caused by the direct contact of the insulin pump with the skin. The adhesion of the adhesive layer can ensure the firm adhesion of the device with the skin, and the bottom film provides a stable fixing platform for the insulin pump. This layered fixing method not only improves the sealing effect, but also increases the comfort of use. Since the insulin pump does not directly contact the skin, the friction and irritation to the skin are reduced, and the incidence of adverse reactions such as skin allergy is reduced. For patients who need to use the insulin pump for a long time, the use experience can be improved, the discomfort caused by the inadaptability of the device is reduced, and the patient can use the insulin pump for treatment more comfortably.

[0017] (3) In the present application, the adhesive layer of the insulin pump fixing protection device is provided with a breathable sticker with air holes. After fixing the insulin pump, the skin can breathe through the air holes on the breathable sticker, making the skin more comfortable and breathable. In addition, the spacer layer is arranged to leave a space between the breathable sticker and the bottom film, further improving the ventilation effect. The grid structure of the spacer layer and the breathable holes not only increase the air flow channel, but also can quickly drain water after using the device to fix the insulin pump for activities such as bathing and swimming, keeping the wearing place dry. Long-term wearing of the insulin pump may cause the skin to sweat or become damp, and good ventilation performance can reduce the stuffy and uncomfortable feeling of the skin and reduce the risk of skin infection. At the same time, after water activities, the spacer layer can quickly drain water to prevent water from accumulating on the skin surface for a long time, further keeping the wearing place dry, which helps to maintain the healthy state of the skin.

[0024] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.

[0025] As Figures 1-4As shown, the insulin pump fixing and protecting device comprises a sticking layer 1, a bottom film 2 and a film covering 3. The sticking layer 1 has adhesion on one side for sticking to the skin, can tightly adhere to the skin, provides a stable base for the whole device, and ensures its firmness in the patient's daily activities. The bottom film 2 is fixed on the side of the sticking layer 1 without adhesion, and the bottom film 2 is fixed on the non-adhesive side of the sticking layer 1, which serves as an intermediate connecting layer to enhance the overall structural stability of the device and provide a flat fixing platform for the insulin pump. The film covering 3 is attached to the side of the bottom film 2 away from the sticking layer 1, used to stick and wrap the insulin pump, so that the insulin pump is fixed on one side of the bottom film 2, and the film covering 3 cooperates with the bottom film 2 to form a waterproof sealing patch, effectively blocking the intrusion of external moisture, protecting the insulin pump from the influence of a humid environment, especially suitable for patients taking a bath or swimming. This structure not only improves the fixing firmness of the insulin pump, but also enhances its waterproof performance, ensuring that the device can work safely and stably in various environments, reducing the risk of device failure caused by environmental factors, and improving the patient's use experience and life convenience. The insulin pump fixing and protecting device realizes stable fixing and effective protection of the insulin pump through the cooperation of the sticking layer 1, the bottom film 2 and the film covering 3.

[0026] A further improvement of the present embodiment is that the sticking layer 1 has a breathable patch 101 in the middle, which has breathable holes to provide breathability for the skin, avoiding skin heat, sweating or discomfort caused by long-term wearing of the device. The breathable holes allow air circulation, allowing the skin to breathe normally while wearing the device, reducing the risk of skin allergy or infection. At the same time, the breathable patch 101 can also improve the comfort of the patient, so that the device does not cause excessive pressure or irritation to the skin during long-term use. This structure cooperates with the adhesive part of the sticking layer 1 to ensure the firmness of the device and also meets the skin's need for breathability, achieving a balance between fixing and comfort, and improving the overall experience of the patient using the insulin pump fixing and protecting device.

[0027] A further improvement of the present embodiment is that the bottom film 2 is fixed on the breathable patch 101 of the sticking layer 1, which can tightly combine the bottom film 2 with the breathable part of the sticking layer 1, ensuring the stability and functionality of the whole device. The breathable patch 101 itself has breathable holes to provide good breathability and reduce the discomfort of the skin during long-term wearing. The whole device can maintain close contact with the skin during use and allow the skin to breathe through the breathable holes of the breathable patch 101, reducing skin problems that may be caused by long-term wearing.

[0028] A further improvement in this embodiment is that a mesh-structured padding layer 102 is provided between the base film 2 and the breathable patch 101. The padding layer 102 has interconnected ventilation openings, which further enhances the breathability and spatial isolation effect of the device. The mesh structure of the padding layer 102 creates a certain spatial gap between the base film 2 and the breathable patch 101, preventing them from being directly and tightly adhered, thus providing more channels for gas circulation. The ventilation openings further ensure that air can circulate freely in the padding layer 102, allowing the skin to breathe better when wearing the device, reducing the stuffiness and discomfort caused by prolonged wear. It not only improves the breathability of the entire device, but also further reduces the direct pressure of the base film 2 on the skin through the spatial isolation effect of the padding layer 102, increasing wearing comfort. At the same time, the mesh structure and ventilation opening design of the padding layer 102 can quickly expel sweat and moisture from the skin surface, keeping the wearing area dry and reducing the risk of skin infection.

[0029] A further improvement in this embodiment is that the covering 3 includes an edge sealing strip 301, a support frame 302, and an elastic film 303. The edge sealing strip 301 has a "U"-shaped structure, and the side of the edge sealing strip 301 closest to the bottom film 2 is adhesive. This adhesiveness tightly adheres to the bottom film 2, forming a sealed boundary to prevent moisture and external contaminants from seeping in from the edge, ensuring the waterproof performance of the entire device. This design not only enhances the device's sealing performance but also provides a stable foundation for the internal support frame 302 and elastic film 303. The support frame 302 has a "U"-shaped structure and is fixed inside the edge sealing strip 301, providing support for the elastic film 303 and ensuring that the elastic film 303 maintains a certain shape and tension. This support structure allows the elastic film 303 to apply force evenly when wrapping the insulin pump, avoiding loosening or damage to the device due to uneven local force. The elastic film 303 is fixed to the support frame 302, ensuring a tight fit to the shape of the device when wrapping the insulin pump. The overlay 3 not only adheres tightly to the base membrane 2, creating a good seal, but also ensures the stability and safety of the insulin pump during use through the synergistic effect of the support frame 302 and the elastic membrane 303. The adhesive boundary of the sealing tape 301, the structural support of the support frame 302, and the elastic wrapping of the elastic membrane 303 work together to achieve waterproofing and stable fixation of the insulin pump, improving the reliability of the entire device and the user experience.

[0030] A further improvement in this embodiment is that the elastic membrane 303, supported by the support frame 302, protrudes to the side away from the base membrane 2, forming a cavity with a certain space. This protruding structure provides a suitable housing space for the insulin pump, preventing excessive compression when the pump is wrapped. The elastic membrane 303 is transparent and elastic. Its transparent design allows medical staff and patients to directly observe the working status of the insulin pump, including important information such as the device's display screen and indicator lights. This transparency not only facilitates routine device checks but also allows for timely detection and handling of abnormalities, improving safety and reliability. The elastic properties of the elastic membrane 303 enable it to adapt to insulin pumps of different sizes and shapes, providing good wrapping and fit.

[0031] A further improvement in this embodiment is that an adhesive layer 201 for fixing the insulin pump is fixed to the middle of the side of the base film 2 away from the adhesive layer 1. The position of the adhesive layer 201 corresponds to the position of the elastic membrane 303. By setting the adhesive layer 201, which is located in the middle of the base film 2, it is specifically used to fix the insulin pump. Its adhesive design ensures that the insulin pump is firmly adhered to the base film 2, preventing the device from shifting or falling off during use. In addition, it facilitates positioning when fixing the insulin pump, and the adhesive layer 201 makes it easier to apply the covering patch 3, improving the convenience of use. The position of the adhesive layer 201 corresponds to the position of the elastic membrane 303, so that when the insulin pump is wrapped by the elastic membrane 303, it can be accurately placed within the protection range of the elastic membrane 303, further enhancing the stability of the fixation. The side of the adhesive layer 201 away from the base film 2 is adhesive and has a protective layer before use, which can prevent the adhesive layer 201 from sticking to the elastic membrane 303.

[0032] A further improvement in this embodiment is that a sealing strip 5 for wrapping the insulin pump tubing connection is attached to the end of the base film 2 near the cover 3. The sealing strip 5 is adhesive on the side near the base film 2, and its design is an important supplement to the sealing reinforcement of the insulin pump tubing interface. After the base film 2 and cover 3 have sealed the insulin pump body, the sealing strip 5 is torn off and wrapped around the insulin pump tubing interface. The adhesive side of the sealing strip 5 near the base film 2 allows it to adhere tightly around the tubing interface, forming an additional sealing layer. The insulin pump tubing interface is a relatively weak point and is prone to poor sealing. The reinforcement with the sealing strip 5 effectively compensates for this deficiency, further enhancing the waterproof performance of the entire device. This ensures that the insulin pump maintains a good seal under all circumstances, preventing moisture from seeping in from the tubing interface, thereby better protecting the insulin pump and avoiding risks such as equipment malfunction or insulin leakage due to moisture ingress. At the same time, this reinforcement measure also improves the reliability of the device, making patients feel more at ease during use and reducing their concerns about the safety of the equipment.

[0033] A further improvement in this embodiment is that adhesive tape 4 is attached to both ends of the adhesive layer 1, providing additional adhesive area and force, thereby enhancing the fixation of the entire device to the skin and ensuring that the device will not easily shift or fall off during the patient's daily activities or exercise. The design of the adhesive tape 4 provides additional stability to the device, especially when the patient is engaged in more strenuous activities, effectively preventing the device from loosening due to external forces. The upward tilt of the adhesive tape 4 provides upward tension, allowing the device to better distribute the force when subjected to external forces, avoiding loosening or falling off due to excessive localized force.

[0034] In practical applications, the adhesive layer 1 and adhesive tape 4 should be made of soft and elastic materials, including but not limited to non-woven fabric or silicone. The adhesive material for the adhesive layer 1 and adhesive tape 4 can be medical-grade pressure-sensitive adhesive to ensure it adheres firmly to the skin while being easy to remove without causing skin damage. The breathable patch 101 and padding layer 102 should be made of breathable materials, such as breathable polyethylene. The base film 2 needs to have a certain mechanical strength and stability; polyethylene or polypropylene materials of a certain thickness can be used to ensure it is not easily deformed or broken during use. The adhesive layer 201 should use medical-grade pressure-sensitive adhesive to ensure the insulin pump adheres firmly to it. The sealing tape 301 should use medical-grade pressure-sensitive adhesive with strong adhesion to ensure a tight fit. The base membrane 2 forms a good sealing boundary. The material can be polyethylene or polypropylene film to ensure its waterproof performance. The support frame 302 should be made of a material with certain rigidity and elasticity, such as polyester fiber or nylon, to ensure that it can provide stable support for the elastic membrane 303 and maintain its shape when subjected to external force. The elastic membrane 303 should be made of a transparent and highly elastic material, such as polyurethane film or silicone film. These materials not only provide good transparency for easy observation of the insulin pump's working status, but also have excellent elasticity to adapt to insulin pumps of different sizes. The sealing strip 5 should use medical-grade pressure-sensitive adhesive to ensure that it can be firmly wrapped around the interface of the insulin pump tubing to form a good sealing effect. The base of the sealing strip 5 can be polyethylene film.

[0035] When using the device, first, apply the adhesive side of the adhesive layer 1 to the patient's skin, ensuring that the adhesive layer 1 adheres tightly to the skin. At the same time, apply the adhesive tape 4 upwards to the skin to enhance the fixation effect. Then, peel off the film 3 and remove the protective layer of the adhesive layer 201 on the base film 2. Place the insulin pump on the adhesive layer 201 and ensure it adheres firmly. Finally, attach the film 3 back to the base film 2, so that the insulin pump is wrapped inside the elastic film 303. Ensure that the sealing tape 301 adheres tightly to the base film 2 to complete the installation of the entire fixation and protection device. If necessary, peel off the sealing strip 5 and wrap the sealing strip 5 around the interface of the insulin pump tubing.
