Description

Technical Field

[0001] This invention relates to the field of wound protection technology in thoracic surgery nursing, specifically a wound protection device for thoracic surgery nursing. Background Technology

[0002] Thoracic surgery incisions are mostly located in the chest, armpit, and below the xiphoid process. These incisions are relatively long and in special locations, and are greatly affected by breathing, coughing, and activity. Proper wound protection is key to promoting healing, preventing infection, reducing pain, and minimizing complications. The main objectives are to keep the wound clean and dry, prevent incision infection and fat liquefaction, reduce incision traction pain during coughing, turning over, and activity, promote good wound healing, reduce scarring and complications, and facilitate early recovery and ambulation. Wound protection devices are nursing instruments used to fix, reduce tension, protect, and promote healing of thoracic surgical incisions after surgery. They can reduce incision traction, infection, pain, and the risk of dehiscence.

[0003] In thoracic surgery, fixation straps are commonly used for wound protection. While these straps are very simple, they are often difficult to adjust precisely according to the patient's body shape and wound location when wrapped around the outside of the chest and ribs. Furthermore, the straps also secure drainage tubes, making it inconvenient to operate on them after wrapping. Therefore, fixation straps present the problem of being difficult to adjust according to the wound location.

[0004] Combining the above issues, we find that existing wound protection devices for thoracic surgery care are difficult to simultaneously avoid the problems mentioned above. Even if they can be solved, they require the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a wound protection device for thoracic surgery care.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: a wound protection device for thoracic surgery care, including a main body 1, the main body 1 including a fixing strap 11, and a wound adjustment mechanism 2 provided on the outside of the fixing strap 11; The wound adjustment mechanism 2 includes a position adjustment unit 21, which is located inside the fixing band 11. The position adjustment unit 21 is used to flexibly adjust the lateral position of the protective component according to the actual position of the wound.

[0023] As a further definition of the wound adjustment mechanism 2 of the present invention, the position adjustment unit 21 includes several identical adjustment plates 2101. The inner side of the fixing band 11 contacts the outer surface of four of the adjustment plates 2101. Each adjustment plate 2101 has several identical connecting holes 2107 on one side. A locking tube 2105 is fixedly installed on the inner wall of each connecting hole 2107. A locking rod 2106 is threadedly connected to the inner wall of each locking tube 2105. Two movable plates 2102 are fixedly installed on the inner side of the fixing band 11. The outer surface of each movable plate 2102 contacts the outer surface of the adjustment plate 2101. A drive plate 2110 is provided on the inner side of each plate 2102. A guide plate 2108 is slidably connected to the bottom of each drive plate 2110. A fixing plate 2103 is fixedly installed on the bottom surface of each guide plate 2108. The outer surface of each fixing plate 2103 is in contact with the outer surface of the adjusting plate 2101. A sliding groove 2109 is provided on the upper surface of each guide plate 2108. A movable slider 2112 is slidably connected inside each sliding groove 2109. A matching nut 2113 is fixedly installed on the inner wall of each movable slider 2112. A small lead screw 2114 is threadedly connected to the inner wall of each matching nut 2113. Four first pulleys 2117 are provided on the outer side, and the inner walls of two of the first pulleys 2117 are fixedly connected to the outer surface of the small lead screw 2114. A first synchronous belt 2118 is drivenly connected to the outer surface of every two first pulleys 2117. A rotating shaft 2111 is fixedly installed on the inner wall of the other two first pulleys 2117. Two second pulleys 2120 are provided on the outer side of each rotating shaft 2111. The outer surface of each rotating shaft 2111 is fixedly connected to the inner wall of the second pulley 2120. A second synchronous belt 2121 is drivenly connected to the outer surface of every two second pulleys 2120. The inner walls of the two second pulleys 2120 are threaded together. The connecting rod 2119 has its outer surface threadedly connected to the inner wall of the fixing band 11. The outer surfaces of each rotating shaft 2111, the small lead screw 2114, and the connecting rod 2119 are rotatably connected to the inner wall of the guide plate 2108. With the position adjustment unit 21, the lateral position of the protective component can be flexibly adjusted according to the actual position of the wound. Specifically, when the position of the protective component needs to be adjusted, the fixing band 11 and the wound protection component on it can be adjusted to accurately correspond to the wound position of different patients, effectively solving the problem that traditional fixing bands are difficult to adjust accurately according to the wound position. Please see Figure 6Mounting plates 2104 are fixedly installed on the side of the two fixed plates 2103 that are close to each other. The outer surface of each small lead screw 2114 is rotatably connected to the inner wall of the mounting plate 2104. Through the mounting plate 2104, a stable support and rotation base point can be provided for the small lead screw 2114, ensuring that the small lead screw 2114 will not deviate or shake during rotation, thereby ensuring the smooth movement of the moving slider 2112 and improving the accuracy and reliability of position adjustment. Please see Figure 7 Each mounting plate 2104 has a drive rod 2116 rotatably connected to its inner wall. One end of each drive rod 2116 and one end of each small lead screw 2114 are fixedly mounted with a bevel gear 2115. Through the drive rod 2116, medical staff can rotate the drive rod 2116 and use the meshing transmission of the bevel gear 2115 to drive the small lead screw 2114 to rotate synchronously.

[0024] The specific implementation method of this embodiment is as follows: When using the fixation strap 11, an additional adjustment plate 2101 can be added according to the wound location to change the length of the fixation strap 11 and the adjustment plate 2101 to adapt to the lateral size requirements of different patients' chests. In specific operation, first align the additional adjustment plate 2101 with the existing adjustment plate 2101 so that the connecting holes 2107 are interconnected. Then, screw the locking rod 2106 into the corresponding locking tube 2105 until both ends of the locking rod 2106 are respectively fastened to the locking tubes of the adjacent adjustment plates 2101. In section 2105, the adjustment plate 2101 is spliced ​​and fixed, while the moving plate 2102 and the fixed plate 2103 can adapt to the length of the adjustment plate 2101. Medical staff rotate the drive rod 2116, and the bevel gear 2115 at one end of the drive rod 2116 rotates accordingly, meshing with the bevel gear 2115 at one end of the small lead screw 2114, thereby driving the small lead screw 2114 to rotate under the support of the mounting plate 2104. The rotation of the small lead screw 2114 causes the matching nut 2113 threaded to it to rotate under the guidance of the slide groove 2109. The sliding block 2112 drives the drive plate 2110 to slide along the length of the guide plate 2108. The movement of the drive plate 2110 pushes the moving plate 2102 in contact with it. At the same time, when the small lead screw 2114 rotates, the first pulley 2117 on its outer side drives the first pulley 2117 on the rotating shaft 2111 to rotate synchronously through the first synchronous belt 2118. The rotating shaft 2111 rotates accordingly, which in turn causes the second pulley 2120 on the rotating shaft 2111 to drive the second pulley 2120 on the connecting rod 2119 to rotate through the second synchronous belt 2121. Since the connecting rod 2119 is threadedly connected to the fixing belt 11 and its outer surface is rotatably connected to the inner wall of the guide plate 2108, the connecting rod 2119 will fix the moving plate 2102 under the drive of the second pulley 2120. The fixing belt 11 uses rigid material at each place where there is a rod to supply the connecting rod 2119 and locking tube 2105, etc., to ensure the normal use of the connecting rod 2119 and other structures. In this way, the precise adjustment of the lateral position of the protective component is achieved, so that it can accurately correspond to the specific position of the patient's wound.

[0025] Example 2: Please refer to Figure 1 , Figure 2 and Figures 9-11 The present invention provides a technical solution: a wound protection device for thoracic surgery care. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The wound adjustment mechanism 2 also includes a wound tube adjustment unit 22, which is located inside the fixation band 11. The wound tube adjustment unit 22 adjusts the drainage tube connected to the wound according to the adjustment of the position adjustment unit 21, and is used to adjust the drainage tube and the wound.

[0026] As a further definition of the wound adjustment mechanism 2 of the present invention, the wound channel adjustment unit 22 includes two frame plates 2201. The outer surface of each frame plate 2201 is in contact with the outer surface of the adjustment plate 2101. A wound protection plate 2202 is snapped into the interior of each frame plate 2201. A mounting groove 2203 is provided on one side of each wound protection plate 2202. The outer surface of each mounting plate 2104 is fixedly connected to the inner wall of the mounting groove 2203. The inner wall of each wound protection plate 2202 is fixedly connected to the inner wall of the mounting groove 2203. Several identical sliding tubes 2205 are fixedly installed. Each sliding tube 2205 has a lifting rod 2213 slidably connected inside. The outer surface of each lifting rod 2213 is slidably connected to the inside of a wound protection plate 2202. A protective strip 2204 is slidably connected inside the wound protection plate 2202. The upper surface of each protective strip 2204 is fixedly connected to the bottom end of the lifting rod 2213. An air chamber 2212 is formed on the outer surface of each lifting rod 2213. Each air chamber 2212 contains... Each wound protection plate 2202 has an air supply pipe 2214, and a miniature air pump 2215 is fixedly installed on the inner wall of each miniature air pump 2215. Each miniature air pump 2215 is fixedly connected to an output pipe 2211, and each output pipe 2211 is fixedly connected to a ring pipe 2206. The interior of each air supply pipe 2214 is connected to the interior of the ring pipe 2206. An input pipe 2210 is fixedly connected to the interior of each miniature air pump 2215. By incorporating a wound tubing adjustment unit 22, flexible wound protection can be achieved. According to the position adjustment unit 21, the wound tube adjustment unit 22 can be aligned with the wound position as a whole, forming a flexible cover and protection for the wound, avoiding external friction or pulling that could irritate the wound. At the same time, removing the wound protection plate 2202 allows for flexible adjustment of the direction and angle of the drainage tube, preventing the drainage tube from bending or being pulled due to the patient's turning over, coughing, or other movements, ensuring smooth drainage. This solves the problem of inconvenience in operating the drainage tube after the traditional fixation band 11 is wrapped around it. Please see Figure 11 Each input tube 2210 has a guide block 2207 fixedly installed on its outer surface. The interior of each guide block 2207 is slidably connected to the outer surface of the wound protection plate 2202. Through the guide block 2207, the position of the input tube 2210 can be guided and limited, ensuring that the input tube 2210 maintains a stable posture when it moves with the wound protection plate 2202 or when its position is adjusted. Please see Figure 11Each guide block 2207 has a rotating shaft 2208 rotatably connected to its inner wall. Each rotating shaft 2208 has a locking plate 2209 fixedly installed at its bottom end. The upper surface of each locking plate 2209 is in contact with the bottom surface of the guide block 2207. Through the rotating shaft 2208 and the locking plate 2209, when the guide block 2207 drives the input tube 2210 to a suitable position, medical staff can rotate the rotating shaft 2208 until the bottom surface of the locking plate 2209 is tightly attached to the outer surface of the wound protection plate 2202.

[0027] The specific implementation of this embodiment is as follows: After the position adjustment unit 21 is adjusted, the wound tubing adjustment unit 22 is located at the wound position. During use, the protective band 2204 protects the wound. The micro air pump 2215 works to draw in outside air through the input pipe 2210 and deliver it to the ring pipe 2206 through the output pipe 2211. Then, the ring pipe 2206 distributes it to each air supply pipe 2214, and finally it enters the air chamber 2212 of the lifting rod 2213. As the air pressure in the air chamber 2212 increases, the lifting rod 2213, guided by the slide pipe 2205, moves upward. Slide it downwards, causing the protective band 2204 to move down synchronously, so that it forms a moderately flexible fit with the skin around the patient's wound. This can protect the wound without causing excessive pressure. If it is necessary to adjust the direction of the drainage tube or perform wound care operations, the micro air pump 2215 can be controlled in reverse to draw air, so that the air pressure in the air chamber 2212 is reduced. The lifting rod 2213 drives the protective band 2204 to move upwards. The protective band 2204 can be made of medical-grade silicone composite non-woven fabric. Then, the wound protection plate 2202 can be removed as a whole, so that the drainage tube can be easily operated or the wound can be exposed.

[0028] Example 3: Please refer to Figures 1-3 The present invention provides a technical solution: a wound protection device for thoracic surgery care. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The wound adjustment mechanism 2 also includes a fastening adjustment mechanism 3. The fastening adjustment mechanism 3 is located outside the fixation strap 11. The fastening adjustment mechanism 3 is used to adjust in real time according to the tightness of the fixation strap 11 on the patient's chest, so as to ensure that the device can fit the patient's chest securely.

[0029] As a further definition of the fastening adjustment mechanism 3 of the present invention, the fastening adjustment mechanism 3 includes four telescopic belts 301. The bottom surface of each telescopic belt 301 is fixedly connected to the upper surface of the fixed belt body 11. An adhesive tape 302 is fixedly installed at one end of each telescopic belt 301. A connecting belt 306 is fixedly installed at the end of each telescopic belt 301 away from the adhesive tape 302. A movable flexible plate 303 is fixedly installed on the bottom surface of each connecting belt 306. Several identical support rods 305 are slidably connected inside each movable flexible plate 303. Each support rod 305 is fixedly installed on the fixed belt body 11. On the upper part, a protective soft plate 304 is snapped onto the outer surface of each movable soft plate 303. The outer surface of each protective soft plate 304 is in contact with the outer surface of the fixing strap 11. By setting a fastening adjustment mechanism 3, the tightness of the fixing strap 11 can be adjusted in a personalized and real-time manner according to the patient's body shape and chest contour characteristics. The whole can drive the position adjustment unit 21 and the wound tube adjustment unit 22 to change position, ensuring that the device maintains a stable fit without causing the patient an excessively tight feeling of restraint, and ensuring that the position adjustment unit 21 and the wound tube adjustment unit 22 correspond to the wound position.

[0030] The specific implementation method of this embodiment is as follows: When the overall binding and fixing strap 11 is performed, the four telescopic straps 301 can be initially fixed to the sides or back of the patient's chest using adhesive tape 302. At this time, the movable soft plate 303 is in a slidable state on the support rod 305. When the medical staff adjusts the position of the telescopic straps 301 according to the patient's actual feeling and the tightness requirements of the chest, they push the protective soft plate 304 along the length direction of the support rod 305, which drives the movable soft plate 303 and the connecting strap 306 to move synchronously, thereby stretching or contracting the telescopic straps 301. When the fixing strap 11 reaches the appropriate tightness, the pushing is stopped. The protective soft plate 304, at this time, the friction between the support rod 305 and the movable soft plate 303 can temporarily fix the position. If further strengthening of the fixation is required, the adhesive position of the adhesive tape 302 can be adjusted, and the amount of extension of the telescopic tape 301 can be coordinated to achieve precise control of the overall tightness of the fixing tape body 11. In this way, the fastening adjustment mechanism 3 can flexibly adapt to the body shape of different patients, ensuring that the position adjustment unit 21 and the wound tube adjustment unit 22 can still stably correspond to the wound position when the patient moves. It will not cause the device to shift due to being too loose, nor will it affect the patient's breathing or cause skin pressure damage due to being too tight.
