Description

Technical Field

[0001] The present invention relates to the technical field of urology nursing appliances, in particular to a bandage sleeve for urology postoperative nursing care. Background Art

[0002] Urological postoperative dressings are commonly used as an aid in postoperative care, designed to help stabilize the surgical site, promote wound healing, and provide necessary support. Postoperative care for urological procedures (such as prostate and bladder surgeries) requires a particular focus on wound protection, infection prevention, and comfort. Dressings must be designed to meet these basic requirements and can be customized to suit the patient's needs.

[0003] The prior art document CN114788759A provides a dressing sleeve for postoperative care in urological surgery. The dressing sleeve is composed of a first sleeve body and a second sleeve body. The first sleeve body and the second sleeve body are placed on the outside of the penis and then fixed with a receiving cavity, a fixing piece and a Velcro. No secondary damage is caused to the penis during operation. After installation, the inflation of the airbag can protect the penis from collision damage. In addition, the size of the dressing sleeve can be adjusted by adjusting the filling level of the gas in the dressing sleeve.

[0004] When used in the prior art, the bandage is primarily fixed to the male genitals by inflating the airbag, which may exert a certain degree of compression on the wound. This compression may affect wound healing and may even cause pain or bleeding. In addition, the gravity of the bandage fixed to the male genitals may exert a continuous pulling force on the male genitals, especially when the patient is moving, which may cause discomfort, pressure or pain, affecting the blood circulation and functional recovery of the genitals. Moreover, although the inflation of the airbag can provide a certain fixation effect, the genitals are subject to various forces such as friction and pulling during daily activities. These forces may cause the fixation between the airbag and the genitals to become unstable, thereby increasing the risk of the bandage falling off.

[0005] In summary, the existing technology lacks an effective auxiliary fixation technical solution for the bandage sleeve. Summary of the Invention

This can effectively disperse the gravity of the bandage sleeve, reduce the pressure on the genitals, and prevent the bandage sleeve from falling off, while providing patients with greater comfort, stability, and freedom of movement. In addition, by providing a mounting sleeve, the internal compression ring cooperates with spring A to press and fix the T-shaped gauze sleeve when installing the bandage sleeve; when disassembling, pull the pull frame to drive the limit rod to move, and the limit on the bandage sleeve can be released, making it easy to disassemble and quickly replace the T-shaped gauze sleeve in the bandage sleeve.

[0018] 2. The slidable sleeve at one end of the bandage can be easily retracted when the patient urinates, allowing the patient to urinate normally without having to completely remove the bandage, saving the patient time and energy. This is particularly suitable for postoperative recovery periods when excessive manipulation is inconvenient. When not urinating, the sleeve completely covers and protects the genitals, reducing external irritation and contamination of the wound, providing the patient with necessary protection, avoiding external friction or pressure, and facilitating rest and recovery of the genitals.

[0019] 3. The ventilation seat on the removable sleeve allows the exhaust fan to inject air filtered by the medical filter cotton into the dressing sleeve, maintaining ventilation and dryness inside, thereby reducing the risk of moisture and bacterial growth, helping to keep the genital area fresh and comfortable, especially suitable for long-term dressing scenarios. Furthermore, the cross connected to the tension spring B can be stretched to loosen the clamp on the medical filter cotton, facilitating quick and easy filter replacement. With simple operation, the caregiver can ensure the cleanliness and filtration of the filter cotton. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0031] like Figures 1-9The shown embodiment is a bandage sleeve for postoperative care in urological surgery, comprising a fixed shorts 1, a fixed sleeve 2 being fixedly connected to one side of the fixed shorts 1, a mounting sleeve 3 being rotatably connected to the fixed sleeve 2, a bandage sleeve 4 being provided on one side of the mounting sleeve 3, a movable sleeve 5 being slidably provided on one side of the bandage sleeve 4, a transmission rod 6 being rotatably connected to the inner wall of the movable sleeve 5, a ventilation seat 7 being provided at the opening at one end of the movable sleeve 5, and a fixed ring 8 being slidably provided inside the movable sleeve 5.

[0032] like Figure 4 As shown, a rubber sleeve 201 is fixedly connected to one side of the fixing sleeve 2 , and the other end of the rubber sleeve 201 is fixedly connected to the installation sleeve 3 .

[0033] like Figure 5 As shown, a compression ring 301 is provided on the inner wall of one end of the mounting sleeve 3, which is close to the dressing sleeve 4. A plurality of springs A302 are fixedly connected to the inner end of the compression ring 301. The other ends of the springs A302 are fixedly connected to the inner wall of the mounting sleeve 3. Under the action of the springs A302, the compression ring 301 presses one end of the T-shaped gauze sleeve 402 into the compression groove 401, thereby limiting and fixing the T-shaped gauze sleeve 402.

[0034] A pull frame 303 is provided on the installation sleeve 3 in a sliding manner. A spring B304 is fixedly provided on the pull frame 303. The other end of the spring B304 is fixedly connected to the installation sleeve 3. A limit rod 305 is provided on the inner wall of the pull frame 3 in a sliding manner. The limit rod 305 is arranged in an inclined structure, and one end of the limit rod 305 is slidably fitted with the installation sleeve 3. When the pull frame 303 is pushed, it causes the pull frame 303 to retract and separate the two limit rods 305. Then, the installation rod 407 on the wrapping sleeve 4 is aligned with the installation sleeve 3 and inserted into the installation sleeve 3. When the pull frame 303 is released, the spring B304 causes the pull frame 303 to return to its original position, thereby causing the two limit rods 305 to move and cross, thereby limiting and fixing the installation rod 407.

[0035] By installing the dressing sleeve 4 on the mounting sleeve 3, which is rotatably connected to the fixing sleeve 2, and by virtue of the fixed shorts 1 fitting snugly against the body, the dressing sleeve 4 can be secured. This effectively disperses the weight of the dressing sleeve 4, reducing pressure on the genitals and preventing it from falling off, while also providing the patient with greater comfort, stability, and freedom of movement. Furthermore, by providing the mounting sleeve 3, the internal compression ring 301 cooperates with the spring A302 to compress and secure the T-shaped gauze sleeve 402 during installation. During removal, the pull frame 303 is pulled to move the limiting rod 305, releasing the limit on the dressing sleeve 4. This facilitates removal and quick replacement of the T-shaped gauze sleeve 402 within the dressing sleeve 4.

[0036] like Figure 6As shown, a mounting rod 407 is fixedly provided on the bandage sleeve 4, and the mounting rod 407 is movably contacted with the outer wall of the limiting rod 305. A clamping groove 401 is provided at one end of the bandage sleeve 4 close to the mounting sleeve 3, and the inner wall of the clamping groove 401 is adapted to the outer wall of the clamping ring 301. A T-shaped gauze sleeve 402 is provided on the inner wall of one end of the bandage sleeve 4, and a ventilation cavity 403 is provided in the middle of the bandage sleeve 4. A plurality of ventilation holes 404 are provided through the inner wall of the ventilation cavity 403, and a plurality of ventilation pipes 405 are fixedly provided on one side of the ventilation cavity 403. The outer end of the ventilation pipe 405 is slidably matched with the movable sleeve 5, and a positioning hole 406 is provided on the inner wall of one end of the bandage sleeve 4 close to the movable sleeve 5.

[0037] like Figure 7 As shown, a pressing rod 501 is provided at one end of the movable sleeve 5 in a sliding manner. A positioning head 502 is fixedly connected to one end of the pressing rod 501 located inside the movable sleeve 5. The positioning head 502 is movably plugged into the positioning hole 406. A tension spring A503 is fixedly connected to the bottom end of the pressing rod 501. The other end of the tension spring A503 is fixedly connected to the inner wall of the movable sleeve 5. An air guide cavity 504 is provided in the middle of the movable sleeve 5. Two air inlets 505 are provided at the end of the movable sleeve 5 near the ventilation seat 7. By pressing down the pressing rod 501, the positioning head 502 on the pressing rod 501 can be removed from the positioning hole 406. Then, the pressing rod 501 is pushed, causing the pressing rod 501 to drive the movable sleeve 5 to retract.

[0038] like Figure 8 As shown, one end of the transmission rod 6 is fixedly connected to the ventilation seat 7, and a transmission groove 601 is opened on the outer wall of the transmission rod 6. The transmission groove 601 consists of a spiral part and a straight part.

[0039] like Figure 8 As shown, a guide head 801 is fixedly connected to the inner wall of one end of the fixing ring 8. The guide head 801 is slidably engaged with the inner wall of the transmission groove 601. A fixing rod 802 is fixedly connected to one end of the fixing ring 8. The other end of the fixing rod 802 extends through the inner wall of the air guide cavity 504 to the outside and is fixedly connected to the inner wall of the dressing sleeve 4. Under the action of the guide head 801 in the fixing ring 8, the transmission rod 6 with the transmission groove 601 is driven to rotate, so that the transmission rod 6 drives the connected ventilation seat 7 to rotate and move away.

[0040] like Figure 9As shown, an air outlet 701 is provided at a position corresponding to the air inlet 505 on one side of the ventilation seat 7, an exhaust fan 702 is fixedly connected to the inner wall of the ventilation seat 7, a mesh plate 703 is threadedly connected to the opening on one side of the ventilation seat 7, and a cross 704 is slidingly provided on one side of the inner end of the mesh plate 703, and a plurality of tension springs B705 are fixedly connected to the cross 704, and the other end of the tension spring B705 is fixedly connected to the mesh plate 703, and a medical filter cotton 706 is clamped and fixed between the cross 704 and the mesh plate 703. By using the exhaust fan 702 to filter the external air through the medical filter cotton 706, the air is drawn into the ventilation seat 7, and then injected into the air guide cavity 504 through the air outlet 701 and the air inlet 505, and then injected into the ventilation cavity 403 on the dressing sleeve 4 through the ventilation pipe 405, and then blown out through the ventilation hole 404 to realize the flow of air inside the dressing sleeve 4. When the medical filter cotton 706 needs to be replaced, first rotate and remove the mesh plate 703, then pull the cross 704 outward, then take out the old medical filter cotton 706, and then place the new medical filter cotton 706 into the mesh plate 703, loosen the cross 704, and under the action of the tension spring B705, the cross 704 clamps and fixes the medical filter cotton 706.

[0041] Working principle: After urological surgery, first put on the fixed shorts 1, then put the fixed sleeve 2 on the genitals, then put the T-shaped gauze sleeve 402 into the bandage sleeve 4, then put the bandage sleeve 4 on the genitals, and then push the pull frame 303, so that the pull frame 303 drives the two limit rods 305 to retract and separate, and then align the installation rod 407 on the bandage sleeve 4 with the installation sleeve 3 and insert it on the installation sleeve 3, and then when the pull frame 303 is released, under the action of the spring B304, the pull frame 303 is reset, thereby driving the two limit rods 305 to move and cross, and the installation rod 407 is limited and fixed. At this time, the clamping ring 301 on the installation sleeve 3 will press one end of the T-shaped gauze sleeve 402 into the clamping groove 401 under the action of the spring A302, so as to limit and fix the T-shaped gauze sleeve 402;

[0042] During the use of the dressing sleeve 4, the external air is filtered through the medical filter cotton 706 by using the exhaust fan 702, and then drawn into the ventilation seat 7, and then injected into the air guide cavity 504 through the air outlet 701 and the air inlet 505, and then injected into the ventilation cavity 403 on the dressing sleeve 4 through the ventilation pipe 405, and then blown out through the ventilation hole 404 to realize the flow of air inside the dressing sleeve 4. When the medical filter cotton 706 needs to be replaced, first rotate and remove the mesh plate 703, then pull the cross 704 outward, and then take out the old medical filter cotton 706, and then place the new medical filter cotton 706 into the mesh plate 703, loosen the cross 704, and under the action of the tension spring B705, the cross 704 clamps and fixes the medical filter cotton 706;

[0043] When the patient needs to urinate, the pressing rod 501 is pressed down so that the positioning head 502 on the pressing rod 501 can be moved out of the positioning hole 406, and then the pressing rod 501 is pushed so that the pressing rod 501 drives the movable sleeve 5 to be retracted. At this time, under the action of the guide head 801 in the fixed ring 8, the transmission rod 6 with the transmission groove 601 will be driven to rotate, so that the transmission rod 6 drives the connected ventilation seat 7 to rotate and move away, making it convenient for the patient to urinate.
