Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of medical protective equipment, and particularly relates to an anti-static and anti-skid surgical shoe with a silver ion conductive lining. BACKGROUND
[0002] The operating room is a high-precision medical operation place, and has strict requirements on environmental cleanliness, safety and stability. The static electricity phenomenon is easily ignored in the operating room environment, but has a major hidden danger: the static electricity generated by the human body in the process of friction between the surgical gown and the skin, walking and friction with the ground, may adsorb dust particles in the air, and destroy the sterile environment; the tiny sparks generated by static electricity discharge may interfere with the normal operation of precision medical equipment such as electrocardiogram monitors and anesthetizing machines, and even cause fire risks of flammable and explosive disinfectants such as alcohol. At the same time, the floor of the operating room is often in a slippery state due to residual water stains, blood or body fluid leakage after cleaning and disinfection, and the risk of slipping is much higher than that in ordinary environment for medical staff standing and walking for a long time.
[0003] At present, there are related patent technologies of anti-static surgical gowns in the industry, which can realize the static electricity dissipation of the upper body of the human body through conductive fiber fabric, but there is a technical gap in the special anti-static protective equipment for the operating room. The existing protective equipment is mainly divided into two categories: industrial anti-static shoes and ordinary operating room special shoes, both of which cannot simultaneously meet the comprehensive needs of anti-static, anti-skid, sterile, comfortable and other needs in the operating room, and are difficult to directly adapt to the operating room scene for optimization, as follows:
[0004] (1) For the industrial anti-static shoes, the core technology is to realize static electricity dissipation through a metal contact steel sheet conductive structure, and to conduct the static electricity of the human body to the ground, but there are the following limitations: ① the metal contact steel sheet of the shoe sole will reduce the anti-skid performance, and combined with the wet ground (disinfectant, water stain) in the operating room, it will easily cause personnel to fall down; ② the gap between the metal contact steel sheet and the shoe body is easy to leave pollutants, and cannot be completely sterilized, which has a risk of cross infection; ③ the metal contact steel sheet may reflect electromagnetic signals, and interfere with the operation of precision equipment such as high-frequency electrosurgical units and monitors in the operating room; ④ if the edge of the metal contact steel sheet is not smooth, it may scratch the sterile cloth, surgical gown and other sterile barriers, and cause contamination of consumables.
[0005] (2) For the ordinary operating room special shoes, the focus is to solve the comfort, ventilation and basic protection needs, the shoe sole is made of high-temperature resistant rubber and is provided with a grid-shaped or wavy pattern to realize basic anti-skid, and the upper and the sole are integrally formed to facilitate high-temperature disinfection, but there are the following limitations: ① no static electricity dissipation structure is designed, and there is no anti-static function, which cannot dissipate the static electricity of the human body, and there is a risk of equipment interference and dust adsorption; ② the existing anti-skid pattern is easy to form a water film on the wet and slippery ground, and the anti-skid performance is limited, and the wet and slippery ground is easy to slip, and the risk of anti-skid failure is high; ③ part of the upper is low, and the foot protection is insufficient. SUMMARY
[0006] The purpose of the present application is to overcome the defects of poor anti-skid performance of existing industrial anti-static shoes, inadaptation to the disinfection and sterility requirements of operating rooms, and lack of anti-static function and insufficient anti-skid performance of ordinary operating room special shoes, and to provide an anti-static and anti-skid surgical shoe with a silver ion conductive lining to achieve efficient anti-static in the operating room environment, meet the sterility and disinfection requirements of the operating room, enhance foot protection and improve wet and slippery ground anti-skid performance, and improve long-term wearing comfort.
[0007] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:
[0008] An anti-static and anti-skid surgical shoe with a silver ion conductive lining, comprising a shoe body, the shoe body comprising a conductive and anti-skid sole and a closed upper, the closed upper being integrally formed with medical-grade high-temperature-resistant silicone rubber, the conductive and anti-skid sole being integrally formed with medical-grade anti-skid rubber added with carbon black conductive particles, and the conductive and anti-skid sole being fixedly connected with the bottom of the closed upper by vulcanization; a silver ion conductive lining for direct contact with the skin of the foot is fixedly attached to the inner side of the closed upper, and medical conductive glue is connected between the silver ion conductive lining and the conductive and anti-skid sole.
[0009] I. Overall design concept of the present application
[0010] The present application is an anti-static and anti-skid surgical shoe specially designed for operating rooms, which adopts the design principle of "extreme simplicity + core function", focuses on the core needs of anti-static, anti-skid, and prevention of blood splashing, and adopts the extreme simple structure design of "closed upper + silver ion conductive lining + integrated conductive and anti-skid sole", without complex detachable parts, facilitating quick disinfection and operation convenience, and taking into account the sterile, easy-to-disinfect, and comfortable needs of the operating room.
[0011] The closed upper is integrally formed with medical-grade high-temperature-resistant silicone rubber, and has a closed structure, which can effectively prevent blood and body fluids from splashing into the shoe during surgery, avoid foot contamination, reduce the risk of instrument injury, enhance foot protection, and facilitate easy wearing and removal.
[0012] The conductive and anti-skid sole is integrally formed with medical-grade anti-skid rubber added with carbon black conductive particles, and is integrally vulcanized and fixed with the bottom of the closed upper to form a complete shoe body structure; the conductive and anti-skid sole is made of high-elasticity anti-skid material with a Shore hardness of 55~60 degrees, which has good friction performance in dry and wet and slippery environments, and the addition of carbon black conductive particles does not affect the anti-skid properties, realizing the synergy of anti-skid and conductive functions.
[0013] The silver ion conductive lining is attached to the inner side of the closed shoe upper, and can directly contact with the skin of the foot. The silver ion conductive lining is connected with the conductive anti-skid sole by using medical conductive glue, so that the static electricity can be smoothly conducted. In this way, on the one hand, the static electricity generated by human activity can be quickly captured, and on the other hand, the silver ion has excellent antibacterial performance and can inhibit the breeding of bacteria, which is suitable for the sterile requirement of the operating room.
[0014] All materials of the anti-static and anti-skid surgical shoe can withstand high temperature and high pressure disinfection of 134 DEG C and 0.2 MPa, and the conductive performance and structural stability are not affected after disinfection. The overall structure of the shoe body is simplified, there is no redundant part, and the weight is light. The upper surface of the conductive anti-skid sole is attached to the conventional foot bottom curve, without additional protruding structure, reducing the feeling of foot compression, and being suitable for long time standing and walking.
[0015] Second, the anti-static conductive path design of the present application
[0016] The present application adopts the simple and stable "human body-silver ion conductive lining-conductive anti-skid sole-ground" anti-static conductive path, which ensures that the static electricity is quickly and stably discharged, and avoids the risk of static electricity accumulation and discharge. The specific design is as follows:
[0017] (1) Charge collection: the silver ion conductive lining directly contacts with the foot, and the static electricity generated by human walking and rubbing is quickly captured by the silver ion conductive lining through contact conduction, so as to avoid the accumulation of electric charge in the human body;
[0018] (2) Charge conduction: the silver ion conductive lining is closely attached to the conductive anti-skid sole (the integration of the upper and the sole ensures close contact), and the captured static electricity is directly conducted to the conductive anti-skid sole through the silver ion conductive lining;
[0019] (3) Charge discharge: the conductive anti-skid sole is made of rubber material with added carbon black conductive particles, which has stable conductive performance and can finally conduct the electric charge to the ground after contacting with the ground; by adjusting the addition ratio of carbon black particles, the ground resistance of the conductive anti-skid sole is strictly controlled within the safety range of 10 6 Ω~10 9 Ω, which can ensure the quick discharge of static electricity and avoid the risk of electric shock, without affecting the normal operation of medical equipment;
[0020] (4) Rubber surgical ground: as the final static discharge point. Material characteristics: the conductivity of ordinary rubber is poor, but the conductivity of the rubber surgical ground can be significantly improved after special treatment (such as adding conductive materials) during the construction of the operating room ground. The static electricity conducted through the conductive anti-skid sole will finally be conducted to the ground, so as to eliminate the accumulation of static electricity.
[0021] In some specific technical solutions of the present application, the silver ion conductive lining is a silver ion conductive fiber cloth, and the thickness of the silver ion conductive fiber cloth is 0.2mm~1mm.
[0022] In some specific technical solutions of the present application, the silver ion conductive lining is fixedly connected to the inner side surface of the closed shoe upper through a medical-grade high-temperature resistant adhesive. In this way, there is no risk of loosening and falling off, and no redundant structure is added inside the shoe.
[0023] In some specific technical solutions of the present application, the edge of the opening of the closed shoe upper is rounded to reduce the feeling of compression and friction damage when wearing, and to avoid abrasion of the feet.
[0024] In some specific technical solutions of the present application, the lower surface of the conductive and anti-skid sole is provided with a grid-shaped groove pattern to ensure the grip on wet and slippery ground.
[0025] In some specific technical solutions of the present application, the height of the upper of the shoe body is 10-12 cm. This upper height takes into account the protection and convenience of putting on and taking off, and is suitable for the daily putting on and taking off habits of medical staff who need to quickly change clothes.
[0026] In some specific technical solutions of the present application, the thickness of the conductive and anti-skid sole is 4-5 mm, and the edges of the toe and heel of the shoe body are thickened by 0.3-0.6 mm. In this way, the anti-skid stability of the key stress area can be enhanced, and the friction coefficient on the common wet and slippery ceramic tile floor in the operating room is ≥0.8, meeting the safety requirements.
[0027] In some specific technical solutions of the present application, at least one air hole is provided on the side surface of the closed shoe upper. By adopting the side air hole design, both the air permeability when wearing and the penetration of disinfectant media such as disinfectant gas and liquid are ensured, and thorough sterilization inside and outside the shoe is ensured to prevent bacterial growth.
[0028] Preferably, a plurality of air holes are provided, and the plurality of air holes are equidistantly spaced on the same side of the closed shoe upper.
[0029] In some specific technical solutions of the present application, the diameter of the air hole is 6-12 mm, and the distribution spacing is 5-25 mm.
[0030] Compared with the prior art, the present application provides an anti-static and anti-skid surgical shoe with a silver ion conductive lining, which has the following beneficial effects:
[0031] (1) Precise adaptation of anti-static performance to operating room: the present application designs a simple anti-static conductive path, and through the cooperative design of "silver ion conductive lining-conductive and anti-skid sole", the structure is simplified while realizing efficient, safe and stable dissipation of static electricity, and the resistance of the sole to the ground is controlled at 10 6 Ω~10 9The safe range of Omega can effectively avoid the risk of electrostatic adsorption of dust and interference with precision medical equipment, and meets the needs of antibiosis and sterility, filling the technical gap of foot anti-static in operating rooms.
[0032] (2) Anti-skid and anti-pollution: The closed shoe surface can block blood splashing and prevent contamination and instrument puncture risk, ensuring protection; the conductive anti-skid sole with carbon black conductive particles is matched with the grid-shaped groove pattern design suitable for water and blood environment, the friction coefficient of wet ground is greater than or equal to 0.8, which greatly reduces the risk of slipping, and realizes the synergy of conductive and anti-skid functions, and has the functions of "conductive-anti-skid-temperature resistant disinfection".

[0046] Please refer toFigure 1 One embodiment of the present invention provides an antistatic and anti-slip surgical shoe with a silver ion conductive lining, comprising a shoe body, which includes a conductive and anti-slip sole 1 and a closed upper 2. The closed upper 2 is integrally molded from medical-grade high-temperature resistant silicone rubber, forming a closed structure that effectively prevents blood and bodily fluids from splashing into the shoe during surgery, avoiding foot contamination, reducing the risk of instrument punctures, enhancing foot protection, and ensuring ease of putting on and taking off. The conductive and anti-slip sole 1 is integrally molded from medical-grade anti-slip rubber with added carbon black conductive particles. The conductive and anti-slip sole 1 is vulcanized and fixedly connected to the bottom of the closed upper 2 to form a complete shoe structure. The high-elasticity anti-slip material used in the anti-slip sole gives it a Shore hardness of 55-60 degrees. This material has good friction performance in both dry and wet environments, and the addition of carbon black conductive particles does not affect the anti-slip properties, achieving a synergistic effect of anti-slip and conductive functions. The inner side of the closed upper 2 is fully fitted with a silver ion conductive liner 3 for direct contact with the skin of the foot. The silver ion conductive liner 3 is connected to the conductive and non-slip sole 1 by a medical conductive adhesive 4, which allows static electricity to be conducted smoothly. In this way, on the one hand, the static charge generated by human activity can be quickly captured, and on the other hand, silver ions have excellent antibacterial properties, which can inhibit the growth of bacteria and meet the sterile requirements of the operating room.
[0047] By employing a minimalist and stable antistatic conductive path—"human body - silver ion conductive lining - conductive and non-slip sole - earth"—static electricity can be quickly and stably discharged, avoiding the risks of static buildup and discharge. Furthermore, all materials in the antistatic and non-slip surgical shoes can withstand high-temperature and high-pressure sterilization at 134℃ and 0.2MPa without affecting conductivity or structural stability. The overall shoe structure is simplified, with no redundant parts, making it lightweight. The upper surface of the conductive and non-slip sole conforms to the natural curve of the foot, without any additional protruding structures, reducing foot pressure and making it suitable for prolonged standing and walking.
[0048] In some specific embodiments, the silver ion conductive liner 3 is a silver ion conductive fiber cloth with a thickness of 0.2 mm to 1 mm. As an example, the thickness of the silver ion conductive liner can be set to 0.5 mm.
[0049] In some specific embodiments, the silver ion conductive liner 3 is fixedly connected to the inner surface of the closed upper 2 using a medical-grade high-temperature resistant adhesive. This eliminates the risk of loosening or detachment and does not add redundant structures to the shoe's interior.
[0050] In some improved embodiments, such as Figure 1 As shown, the edge of the shoe opening of the closed upper 2 is rounded, which can reduce the feeling of pressure and friction damage when wearing, and avoid chafing the feet.
[0051] In some improved embodiments, the lower surface of the conductive anti-slip sole 1 is provided with a grid-like groove pattern 11 to ensure grip on wet and slippery surfaces. Specifically, the grid-like groove pattern is evenly distributed, which can quickly drain water stains and blood between the sole and the ground, preventing the formation of a water film that would cause the anti-slip effect to fail.
[0052] In some specific embodiments, the upper height of the shoe body is 10cm to 12cm. This upper height balances protection and ease of putting on and taking off, adapting to the daily dressing habits of medical personnel who need to quickly change clothes. As an example, the upper height of the shoe body can be set to 10mm.
[0053] In some specific embodiments, the conductive anti-slip sole 1 has a thickness of 4mm to 5mm; the edges of the toe and heel of the shoe body are thickened by 0.3mm to 0.6mm respectively. This enhances the anti-slip stability of key stress areas, and tests show a coefficient of friction ≥0.8 on commonly slippery tile floors in operating rooms, meeting safety requirements. As an example, the thickness of the conductive anti-slip sole 1 can be set to 4mm, with the edges of the toe and heel of the shoe body thickened by 0.5mm respectively.
[0054] In some improved embodiments, at least one ventilation hole 21 is provided on the side of the closed upper 2. By adopting the side ventilation hole design, both breathability is ensured and disinfection media such as disinfectant gases and liquids can be easily penetrated, ensuring thorough sterilization of the inside and outside of the shoe and preventing bacterial growth.
[0055] Preferably, there are multiple ventilation holes 21, which are evenly spaced on the same side of the closed shoe upper 2.
[0056] Preferably, the diameter of the vent holes 21 is 6mm~12mm, and the spacing between them is 5mm~25mm.
[0057] As an example, such as Figure 1 As shown, four ventilation holes 21 are provided on one side of the closed shoe upper 2. The maximum diameter of the ventilation holes 21 can be set to 10mm, and the distribution spacing can be set to 10mm. In some other embodiments, the diameter of the ventilation holes 21 can also be set to 6mm, 8mm, 12mm, etc., and the distribution spacing can also be set to 5mm, 15mm, 20mm, 25mm, etc.
[0058] The above embodiments are merely illustrative of the concept and technical solution of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
