Description

A postoperative infection prevention and protection device for urology Technical Field

[0001] This invention relates to the field of postoperative protection technology, and in particular to a postoperative infection prevention and protection device for urological surgery. Background Technology

[0002] Urology is a medical field that focuses on diseases of the urinary and male reproductive systems. It involves organs such as the kidneys, ureters, bladder, and urethra, as well as the testes, epididymis, and prostate in men. Physicians in this field are responsible for diagnosing and treating various urinary system diseases, such as kidney stones, cystitis, benign prostatic hyperplasia, and kidney tumors. For diagnosis, urologists typically use imaging techniques (such as ultrasound, CT, and MRI), urinalysis, and endoscopy to determine the nature and extent of the disease. Treatment methods are diverse, with surgical approaches ranging from open surgery to minimally invasive procedures, such as laparoscopic surgery and transurethral surgery.

[0003] Postoperative infection is a significant concern affecting patient recovery after urological surgery. Existing infection prevention techniques typically include postoperative antibiotics, sterile dressings, and closed drainage systems. However, these methods often cannot completely prevent infection, and some may even lead to other complications. Therefore, developing novel infection protection devices is crucial. Postoperative infection protection devices for urology are designed to form a physical barrier, preventing the invasion of external microorganisms while allowing wound ventilation to promote healing. The use of this device can significantly reduce the incidence of postoperative infection, thereby shortening hospital stays, reducing treatment costs, and improving postoperative quality of life. Furthermore, patients using this device experience less psychological stress during recovery, as they have better assurance regarding infection risk control. Some urological surgeries involve sensitive areas, making postoperative care more complex. Postoperative care not only needs to focus on the recovery of sensitive areas but also consider how to avoid further damage to the wound. Moderate exercise can help accelerate recovery, but during exercise, patients can easily touch the wound accidentally, potentially causing secondary injury and further limiting their mobility.

[0004] Assessing the patient's recovery is crucial during postoperative care. Urine test results are a key indicator. When urine testing is required, samples are usually collected temporarily. However, urine may accidentally spill during defecation, potentially contaminating the wound and increasing the risk of infection, especially concerning hygiene in the genital area. Therefore, postoperative care requires close attention to the patient's urination and defecation habits to ensure cleanliness and safety of sensitive areas and minimize the chance of infection. This necessitates meticulous observation and skillful nursing techniques from caregivers to provide more attentive care and ensure a smooth recovery.

[0005] While existing postoperative infection prevention methods in urology can address some infection issues through medication, their solutions for preventing infection in the external parts of the urinary system that are in direct contact with air after surgery are not yet mature enough.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Example

[0032] A postoperative infection prevention and protection device for urology according to the present invention is described below with reference to Figures 1-9.

[0033] As shown in Figures 1-3, an embodiment of the present invention provides a postoperative infection prevention and protection device for urology, comprising: a protective system 1, a fixing component 2, a splash-proof component 3, and a valve component 4. The fixing component 2 is installed on the human body. It can be adjusted to fit different body types. The protective system 1 is detachably connected to the fixing component 2. When providing protection, the protective system 1 is connected to the human body via the fixing component 2, allowing it to function even during human movement and preventing it from being affected by the body's condition. The splash-proof component 3 is installed within the fixing component 2. It disperses urine excreted by the body, reducing splashing caused by impact. The valve component 4 is disposed within the protective system 1 and fixedly connected to it. The main function of the valve component 4 is to seal the protective system 1 after urine is excreted, preventing external contamination of the protective system 1.

[0034] The fixing component 2 includes a large strap 21, two connecting straps 22, two leg straps 23, two telescopic straps 24, and a locking buckle 25. The large strap 21 and the two leg straps 23 work together to secure the entire protective device tightly to the human body. The telescopic straps 24 allow the position of the protective system 1 to be adjusted as needed, providing infection protection even during normal walking. One end of each of the two connecting straps 22 is fixedly connected to the large strap 21, while the other end is detachably connected to the protective system 1. The main function of the two connecting straps 22 is to restrict the position of the protective system 1. The connecting straps 22 can be adjustable, allowing the protective system 1 to adapt to different body types by adjusting their length. The two leg straps 23 are symmetrically arranged on both sides of the protective system 1 and are detachably connected to it. Once the position of the protective system 1 is determined, the two leg straps 23 are adjusted to bind it to the thighs, restricting the position of the protective system 1. The two telescopic straps 24 are movably connected to both ends of the large strap 21. One end of the telescopic belt 24 is inherently connected to a rack, which passes through the locking buckle 25. By adjusting the locking buckle 25, the two telescopic belts 24 can move in opposite or relative directions. The locking buckle 25 is used to lock the two telescopic belts 24. When the two telescopic belts 24 have moved to the appropriate position, stopping the adjustment of the locking buckle 25 can fix the position of the telescopic belts 24.

[0035] The latch 25 includes a lock housing 251, a locking gear 252, and a knob 253. The lock housing 251 is typically made of aluminum alloy, which provides high hardness while maintaining excellent mechanical properties, ensuring the stability and durability of the latch 25. Two telescopic straps 24 are slidably connected to the lock housing 251 to limit their position relative to the locking gear 252. Both telescopic straps 24 are engaged with the locking gear 252; adjusting the rotation direction of the locking gear 252 loosens or tightens the two telescopic straps 24. The locking gear 252 is rotatably connected to the lock housing 251, preventing deviation during rotation. The knob 253 is fixedly connected to the locking gear 252. By rotating knob 253, locking gear 252 is rotated, which in turn drives the two telescopic straps 24 to move in opposite or relative directions, making the large strap 21 more securely bound to the body and preventing slippage. This allows the large strap 21 to provide stable support and a comfortable user experience during daily activities.

[0036] The protective system 1 includes a protective chamber 11, a collection chamber 12, a urination tube 13, and a sealing joint 14. The protective chamber 11 is typically made of polyurethane, a material that combines flexibility and abrasion resistance, providing a degree of comfort while offering protection. Polyurethane (PU) is a highly flexible material widely used in the medical field, especially in the manufacture of rigid protective gear. Polyurethane has high flexibility and elasticity, effectively absorbing impact. Its high surface hardness and abrasion resistance allow it to withstand wear and tear during daily use, extending the lifespan of the protective gear. Some polyurethane materials have good breathability; when used with a sterilization layer, this helps reduce dampness and discomfort while preventing infection, enhancing comfort. Surface-modified polyurethane can increase its hydrophilicity or reduce its surface energy, reducing irritation and allergic reactions upon skin contact. Adding antibacterial agents to the polyurethane material can prevent bacterial growth, reduce the risk of infection, and improve the safety of the material in contact with the skin. One end of the collection chamber 12 is fixedly connected to the protective chamber 11. The collection chamber 12 is primarily made of polycarbonate, which offers high toughness and transparency while also being impact-resistant. Polycarbonate is transparent with high light transmittance, similar to glass. Its excellent transparency allows for easy observation of the internal structure. However, it is lightweight and less prone to breakage than glass. Polycarbonate retains its physical properties at relatively high temperatures, typically operating within a temperature range of -40℃ to 120℃. Therefore, it is perfectly suited for urine storage and discharge. Polycarbonate can be processed and molded using various methods such as injection molding, extrusion, and thermoforming to meet different needs. The other end of the collection chamber 12 is fixedly connected to one end of the discharge tube 13. The discharge tube 13 is usually made of a soft material, such as polyurethane, which has high tear resistance and tensile strength, meeting the requirements for long-term use. A sealing joint 14 is fixedly installed at the other end of the discharge tube 13. The sealing joint 14 is mainly used to fix the valve assembly 4 and the push rod assembly 5, ensuring that the valve assembly 4 and the push rod assembly 5 can only operate within the range defined by the sealing joint 14.

[0037] The protective chamber 11 has arc-shaped grooves on both sides to restrict its position on the inner thigh. These grooves not only provide necessary space restriction but also reflect a design that considers ergonomics and freedom of movement. The shape of the grooves closely follows the contour of the inner thigh, effectively conforming to the leg structure and ensuring the protective chamber 11 does not easily slip or shift during use. This allows the protective chamber 11 to remain stable under various movement conditions, increasing the user's sense of security and comfort. The depth and width of the grooves are precisely calculated to accommodate the needs of users with different body types. This structural design helps to distribute pressure during exercise or activity, avoiding excessive localized pressure on muscles and joints, and reducing the risk of injury.

[0038] As shown in Figures 4-7, the valve assembly 4 includes a fixed disc 41, a movable disc 42, multiple sealing blocks 43, multiple limit blocks 44, and multiple limit blocks 45. The fixed disc 41 is fixedly connected to the sealing section 14. Multiple limit grooves 411 are provided on the fixed disc 41 to restrict the movement direction of the limit blocks 44, allowing them to move within a set range. The sealing blocks 43 have a fan-shaped cross-section. When the multiple sealing blocks 43 are closed, they can completely close together, resembling the shutter structure of a camera. The multiple limit blocks 44 are fixedly connected to the multiple sealing blocks 43. When the limit blocks 44 slide along the limit grooves 411, they move the sealing blocks 43. The multiple sealing blocks 43 abut against each other to restrict the movement of all sealing blocks 43, ensuring perfect closure and opening. The multiple limit blocks 45 are fixedly connected to the multiple sealing blocks 43. Limiting block 1 44 and limiting block 2 45 are located on opposite sides of the blocking block 43. The control process among the three is as follows: limiting block 2 45 controls the operation of the blocking block 43, and limiting block 1 44 restricts the overall movement of the blocking block 43. Multiple limiting blocks 1 44 are slidably connected to the fixed plate 41. Multiple limiting blocks 2 45 are slidably connected to the movable plate 42. The movable plate 42 has a limiting groove 2 421, and the limiting block 2 45 is set in the limiting groove 2 421. By rotating the movable plate 42, the limiting block 2 45 can move accordingly, ultimately causing the multiple blocking blocks 43 to converge inward, thereby achieving the purpose of blocking the urinary catheter 13. Similarly, by controlling the opening and closing of the valve assembly 4, the flow rate and velocity of urine can be controlled to meet the needs of different patients.

[0039] The postoperative infection prevention and protection device for urology also includes a push rod assembly 5 for rotating the movable disc 42. The push rod assembly 5 includes a push rod 51 and a limiting rod 52. The push rod 51 is fixedly connected to the movable disc 42. The limiting rod 52 is fixedly connected to the push rod 51. The limiting rod 52 is slidably connected to the sealing section 14. Pushing the push rod 51 allows the movable disc 42 to rotate within its confined space. The limiting rod 52 ensures that the push rod 51 always rotates around the same center of rotation as the movable disc 42, preventing it from shaking or loosening and affecting the sealing effect.

[0040] As shown in Figures 8 and 9, the splash guard assembly 3 includes a splash guard 31, a second knob 32, two second latches 33, a second locking gear 34, and two first racks 35. It is mainly used to prevent urine splashing. The splash guard 31 is slidably connected to the protective chamber 11, making it easier to replace. The two second latches 33 are slidably connected to the splash guard 31. By adjusting the position of the two second latches 33, they interact with the protective chamber 11, achieving the purpose of locking the splash guard 31. The two first racks 35 are fixedly connected to the two second latches 33 respectively. The second locking gear 34 meshes with the two first racks 35. The second locking gear 34 is rotatably connected to the splash guard 31. The second knob 32 is fixedly connected to the second locking gear 34. By rotating knob 32, locking gear 34 is driven to rotate, which in turn drives two racks 35 to move in opposite or opposite directions, so that they intersect or disconnect with the protective chamber 11, thereby achieving the purpose of locking or opening the splash guard 31.

[0041] The splash guard 31 has multiple splash holes 311. The multiple splash holes 311 are used to disperse urine. The distribution of the multiple splash holes 311 can effectively extend the distribution range of urine, so that when urine comes into contact with the splash guard 31, it is no longer concentrated at one point, but is evenly dispersed to prevent urine from splashing.

[0042] In summary, the working principle of a postoperative infection prevention and protection device for urology according to the present invention is described below:

[0043] As shown in Figures 1-9, when wearing the protective system, the protective chamber 11 of the protective system 1 covers the lower body. Then, the two telescopic straps 24 are inserted into both ends of the large strap 21, and then into the locking case 251 of the buckle 25. Turning the knob 253 moves the two telescopic straps 24 in opposite directions, thus securing the large strap 21. The leg straps 23 are then fixed to the groin to restrict the position of the protective system 1, preventing relative displacement with movement during use, and ensuring the protective chamber 11 fits snugly against the lower body for increased sealing. The end of the urination tube 13 furthest from the collection chamber 12 is then connected to an external collection device or used for urination. During urination, the push rod 51 is moved, causing the movable disc 42 to rotate, which moves the multiple sealing blocks 43 within a restricted range, eventually moving them away from the center of the valve assembly 4, opening the valve assembly 4 and thus opening the urination tube 13. During urination, the splash guard 31 has multiple splash holes 311. The distribution of these holes effectively extends the range of urine dispersion, preventing urine from concentrating at a single point upon contact with the splash guard 31 and instead dispersing evenly to prevent splashing. When urination is finished, simply move the push rod 51 in the opposite direction to rotate the movable disc 42, allowing the multiple blocking blocks 43 to move within a restricted range and ultimately converge at the center of the valve assembly 4, closing the valve assembly 4 and sealing the urination pipe 13.
