Description

Technical Field

[0001] This invention relates to the field of medical debridement equipment technology, specifically a portable outdoor debridement kit for general surgery. Background Technology

[0002] Wound debridement is a crucial step in surgical nursing. It involves removing foreign objects from open wounds, excising necrotic, devitalized, and severely contaminated tissue, and suturing the wound to minimize contamination and even create a clean wound, thus promoting healing and facilitating the recovery of function and morphology of the injured area. Especially in emergency rescue at accident scenes, it is sometimes necessary to clean or bandage a patient's wound on-site. However, most accident scenes are dirty and unsanitary, lacking suitable spaces for wound cleaning, and medical waste generated during the process cannot be disposed of indiscriminately, causing considerable inconvenience to medical personnel.

[0003] Most existing medical kits are box-shaped structures with an opening at the top that can be opened. When using the kit, opening the lid directly during wound cleaning exposes contaminants inside the kit to the outside, which can easily cause the contaminants to spread to other parts of the patient's body and cause secondary contamination.

[0004] Therefore, this invention proposes a portable outdoor wound cleaning kit for general surgery to compensate for and improve the shortcomings of existing technologies. Summary of the Invention

[0005] In view of the above problems, the present invention provides a portable outdoor wound cleaning kit for general surgery, which can effectively solve the problem of contaminants being directly exposed to the outside in the prior art, easily leading to the spread of contaminants to the outside. To achieve the above objective, the embodiments of this application provide the following technical solution:

[0006] This invention discloses a portable outdoor wound cleaning kit for general surgery, including a box body. The box body is provided with a flipping mechanism to reduce the outward diffusion of contaminants. The flipping mechanism is provided with a scraping mechanism to reduce contaminant residue. The box body is also provided with a limiting mechanism to prevent the flipping mechanism from shaking. The box body is provided with a supporting mechanism to prevent the box body from tilting.

[0007] The flipping mechanism includes hollow rotating shafts symmetrically connected to the side wall of the box. A semi-circular plate for receiving pollutants is fixedly connected between the two hollow rotating shafts. A top cover is fixedly connected to the top of the box. A cover plate is rotatably connected to the surface of the top cover. The two ends of the cover plate are rotatably connected to the outside of the hollow rotating shafts.

[0008] Furthermore, a gear is rotatably connected to the outside of the hollow shaft, the gear meshes with a rack, the rack is slidably connected to the outside of the housing, and a lever is rotatably connected to the end of the rack away from the gear, the middle of the lever being rotatably connected to the side of the housing.

[0009] Furthermore, a ratchet is rotatably sleeved on the outside of the hollow shaft, and the ratchet is located in the cavity of the gear. A pawl is also rotatably connected in the cavity of the gear, and the pawl meshes with the ratchet. An elastic plate is also fixedly connected in the cavity of the gear, and the side of the elastic plate is in close contact with the side of the pawl.

[0010] Furthermore, the scraping mechanism includes a mounting shaft that horizontally penetrates two hollow rotating shafts, with both ends of the mounting shaft extending outside the hollow rotating shafts, and both ends of the mounting shaft are fixedly connected to a fixing bracket, which is fixedly connected to the side of the housing.

[0011] Furthermore, sleeves are symmetrically fixedly connected to the outside of the mounting shaft. A sliding rod is slidably sleeved in the cavity of the end of each sleeve away from the mounting shaft. A first scraper for scraping off contaminants from the inner wall of the semi-circular plate is fixedly connected to the end of the sliding rod away from the sleeve. A first spring is provided in the cavity of the sleeve. One end of the first spring is fixedly connected to the sleeve, and the other end of the first spring is fixedly connected to the sliding rod. A first limiting block for restricting the movement distance of the sliding rod is also fixedly connected inside the cavity of the sleeve.

[0012] Furthermore, guide rods are fixedly connected to the cavities at both ends of the first scraper, and a second scraper for scraping off contaminants at both ends of the semicircular plate is slidably connected to the outside of each guide rod. A second spring that pushes the second scraper toward the end face of the semicircular plate is sleeved on the outside of the guide rod, and a second limiting block that restricts the movement distance of the second scraper is fixedly connected to the cavity of the first scraper.

[0013] Furthermore, the limiting mechanism includes U-shaped rods symmetrically slidably connected to the housing to prevent the semicircular plate from rotating, each of the U-shaped rods being slidably inserted into the housing and positioned directly below the semicircular plate.

[0014] Furthermore, a return spring is sleeved on the outside of the U-shaped rod, and the return spring is located outside the box. A lever is also rotatably connected to the outside of the box. One end of the lever is slidably connected to the outside of the U-shaped rod, and the lever is rotatably connected to a protrusion on the side of the box. The other end of the lever extends to the bottom of the hollow rotating shaft. An arc-shaped protrusion for pushing the lever is fixedly connected to the side of the cover plate. The arc-shaped protrusion is slidably connected to the end of the lever away from the U-shaped rod.

[0015] Furthermore, the support mechanism includes a storage slot at the bottom of the box, and symmetrically rotatably connected inside the storage slot to support rods for preventing the box from tilting. Each support rod has a torsion spring sleeved on its pivot shaft. One end of the torsion spring is fixedly connected to the support rod, and the other end of the torsion spring is fixedly connected to the outside of the box.

[0016] Furthermore, the support mechanism also includes an L-shaped limiting rod that is slidably connected to the side of the box to prevent the support rod from unfolding. The vertical section of the L-shaped limiting rod extends into the storage groove, and the bottom of the L-shaped limiting rod has an inclined surface. The horizontal section of the L-shaped limiting rod extends to the outside of the box. A compression spring is fixedly connected to the top of the L-shaped limiting rod, and the end of the compression spring away from the L-shaped limiting rod is fixedly connected to the box.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This device is equipped with a flipping mechanism, which effectively collects all rinsing fluid, blood, and waste tissue by a semi-circular plate. After operation, the semi-circular plate can be flipped by a gear and rack drive to completely lock the contaminants inside the box. With the top cover closed, a sealed isolation space is formed, blocking the diffusion path of contaminants to the external environment. This not only protects the patient's uninjured parts from cross-infection but also ensures the operational safety of medical staff, solving the pain point of poor sterile environment in outdoor sites.

[0019] 2. This device is equipped with a scraping mechanism. When the semicircular plate is flipped by the flipping mechanism, the stationary scraper will slide against the inner wall and end face of the semicircular plate under the action of the spring force, automatically scraping off the sticky contaminants attached to the plate wall. This prevents the dirt from drying and solidifying inside the box, which not only reduces the labor intensity of medical staff for subsequent cleaning and disinfection, but also ensures that the wound cleaning box can keep the inside clean and be ready for use at any time during continuous use.

[0020] 3. This device is equipped with a limiting mechanism. When the cover is opened for operation, the limiting mechanism automatically locks the semicircular plate and uses a U-shaped rod inserted under the semicircular plate to prevent the semicircular plate from rotating, thus preventing the pollutants at the bottom of the box from spreading to the outside when the semicircular plate is used to collect pollutants.

[0021] 4. This device is equipped with a support mechanism that uses the elastic force of a torsion spring to allow the support rod to automatically unfold and support itself on the ground. This prevents the box from tilting during the rotation of the semicircular plate, thereby preventing the spread of pollutants inside the box to the outside and further reducing the threat of pollutants to patients and medical staff.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to embodiments.

[0036] See Figures 1 to 10 This embodiment of a general surgery portable outdoor wound cleaning kit includes a box body 10. The box body 10 is provided with a flipping mechanism 20 for reducing the outward diffusion of contaminants. The flipping mechanism 20 is provided with a scraping mechanism 30 for reducing contaminant residue. The box body 10 is also provided with a limiting mechanism 40 to prevent the flipping mechanism 20 from shaking. The box body 10 is provided with a support mechanism 50 to prevent the box body 10 from tilting.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The flipping mechanism 20 includes hollow rotating shafts 202 symmetrically connected to the side wall of the box 10. A semi-circular plate 201 for receiving pollutants is fixedly connected between the two hollow rotating shafts 202. A top cover 203 is fixedly connected to the top of the box 10. A cover plate 204 is rotatably connected to the surface of the top cover 203. Both ends of the cover plate 204 are rotatably connected to the outside of the hollow rotating shafts 202.

[0038] A gear 205 is rotatably connected to the outside of the hollow rotating shaft 202. The gear 205 meshes with a rack 206. The rack 206 is slidably connected to the outside of the housing 10. A lever 207 is rotatably connected to the end of the rack 206 away from the gear 205. The middle part of the lever 207 is rotatably connected to the side of the housing 10. A slot is provided at the connection between the lever 207 and the rack 206. The rack 206 is slidably connected in the slot of the lever 207. When the lever 207 pushes the rack 206 to move, the bottom of the rack 206 slides in the slot of the lever 207.

[0039] A ratchet 208 is rotatably sleeved on the outside of the hollow shaft 202, and the ratchet 208 is located in the cavity of the gear 205. A pawl 209 is also rotatably connected in the cavity of the gear 205. The pawl 209 meshes with the ratchet 208. An elastic plate 210 is also fixedly connected in the cavity of the gear 205. The side of the elastic plate 210 fits tightly against the side of the pawl 209.

[0040] In practice, when cleaning the wound, first rotate the cover plate 204 to open the opening at the top of the top cover 203. The contaminants cleaned from the wound are then poured into the semi-circular plate 201 through the opening of the top cover 203. After one cleaning is completed, rotate the cover plate 204 again to cover the opening of the top cover 203. Then, by pressing the lever 207, since the middle part of the lever 207 is rotatably connected to the outside of the housing 10, the lever 207 pushes the rack 206 upward when it rotates. When the rack 206 moves upward, it drives the gear 205 to rotate synchronously. Because the pawl 209 is elastically pushed by the elastic plate 210, it meshes with the ratchet 208. Therefore, when the gear 205 rotates, it synchronously drives the hollow shaft 202 to rotate. The rotating hollow shaft 202 drives the semicircular plate 201 to rotate 180 degrees. After the semicircular plate 201 rotates, the lever 207 is lifted upward again, and the lever 207 drives... As the rack 206 moves downward, due to the unidirectional rotation characteristics of the ratchet 208 and pawl 209, the rack 206 drives the gear 205 to rotate outside the hollow shaft 202. At this time, the gear 205 does not drive the hollow shaft 202 to rotate. During the rotation of the semicircular plate 201, the contaminants in the semicircular plate 201 slide into the box 10. After the semicircular plate 201 rotates 180 degrees, it can prevent the contaminants inside the box 10 from spreading outward. During the next debridement, after the cover 204 is opened again, the contaminants put into the semicircular plate 201 during the previous debridement have already slid into the box 10. The semicircular plate 201 can prevent the contaminants inside the box 10 from spreading outward. The semicircular plate 201 in the flipping mechanism 20 acts as a temporary receiving container, collecting all medical waste and other contaminants into the box 10, preventing contaminants from dripping directly into the outdoor environment or the patient's healthy parts, and blocking the path of cross-infection.

[0041] See Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 The scraping mechanism 30 includes a mounting shaft 301 that horizontally passes through two hollow rotating shafts 202. Both ends of the mounting shaft 301 extend to the outside of the hollow rotating shafts 202, and both ends of the mounting shaft 301 are fixedly connected to a fixing bracket 302. The fixing bracket 302 is fixedly connected to the side of the housing 10.

[0042] A sleeve 303 is symmetrically fixedly connected to the outside of the mounting shaft 301. A slide rod 304 is slidably sleeved in the cavity of the end of each sleeve 303 away from the mounting shaft 301. A first scraper 305 for scraping off contaminants from the inner wall of the semi-circular plate 201 is fixedly connected to the end of the slide rod 304 away from the sleeve 303. A first spring 306 is provided in the cavity of the sleeve 303. One end of the first spring 306 is fixedly connected to the sleeve 303, and the other end of the first spring 306 is fixedly connected to the slide rod 304. A first limiting block 310 is also fixedly connected inside the cavity of the sleeve 303 to limit the movement distance of the slide rod 304. The first limiting block 310 limits the movement distance of the first scraper 305, thereby preventing the first scraper 305 from detaching from the arc-shaped working surface of the semi-circular plate 201.

[0043] Guide rods 309 are fixedly connected to the cavities at both ends of the first scraper 305. A second scraper 307 for scraping away contaminants from both ends of the semi-circular plate 201 is slidably connected to the outside of each guide rod 309. A second spring 308 is sleeved on the outside of each guide rod 309 to push the second scraper 307 towards the end face of the semi-circular plate 201. A second limiting block 311 is fixedly connected to the cavity of the first scraper 305 to limit the movement distance of the second scraper 307. The second limiting block 311 restricts the movement distance of the second scraper 307, preventing the second scraper 307 from detaching from the working surfaces at both ends of the semi-circular plate 201 when the semi-circular plate 201 rotates.

[0044] In specific operation, during the rotation of the semicircular plate 201, under the elastic force of the first spring 306, the slide rod 304 moves away from the sleeve 303, thereby tightly pressing the first scraper 305 at the end of the slide rod 304 away from the sleeve 303 against the arc surface of the semicircular plate 201. Therefore, when the semicircular plate 201 rotates, the mounting shaft 301 remains fixed by the fixing bracket 302, and the first scraper 305 can scrape off the contaminants attached to the inner arc surface of the semicircular plate 201. Similarly, under the elastic force of the second spring 308, the second scraper 307 moves along the guide rod 309 towards both ends of the first scraper 305, so that the second scraper 307 tightly presses against both ends of the semicircular plate 201. 7. The contaminants attached to both ends of the semicircular plate 201 are scraped off. The contaminants temporarily stored in the semicircular plate 201 are fully slid into the box 10 by the first scraper 305 and the second scraper 307. The scraping mechanism 30 realizes the automatic cleaning of the semicircular plate 201, prevents the dirt from drying and solidifying inside the semicircular plate 201, reduces the labor intensity of medical staff for subsequent cleaning and disinfection, ensures the internal cleanliness of the wound cleaning box during continuous use, and reduces the diffusion of residual contaminants inside the semicircular plate 201 to the outside. The first limiting block 310 and the second limiting block 311 simultaneously limit the movement distance of the first scraper 305 and the second scraper 307, and prevent the first scraper 305 and the second scraper 307 from popping out of the semicircular plate 201 when the semicircular plate 201 is rotated.

[0045] See Figure 1 , Figure 2 , Figure 3 and Figure 9 The limiting mechanism 40 includes U-shaped rods 401 symmetrically slidably connected to the housing 10 to prevent the semicircular plate 201 from rotating. Each U-shaped rod 401 is slidably inserted into the housing 10 and is located directly below the semicircular plate 201.

[0046] A return spring 402 is sleeved on the outside of the U-shaped rod 401, and the return spring 402 is located outside the housing 10. A lever 403 is also rotatably connected to the outside of the housing 10, and the lever 403 is rotatably connected to a protrusion on the side of the housing 10. The middle part of the lever 403 is rotatably connected to the protrusion on the side of the housing 10. One end of the lever 403 is slidably connected to the outside of the U-shaped rod 401, and the other end of the lever 403 extends to the bottom of the hollow rotating shaft 202. An arc-shaped protrusion 404 for pushing the lever 403 is fixedly connected to the side of the cover plate 204. The arc-shaped protrusion 404 is slidably connected to the end of the lever 403 away from the U-shaped rod 401.

[0047] In actual operation, when the cover plate 204 is opened, the cover plate 204 drives the arc-shaped protrusion 404 to rotate around the hollow rotating shaft 202. The arc-shaped protrusion 404 lifts one end of the lever 403, causing the bottom of the lever 403 to push the U-shaped rod 401 to overcome the elastic force of the return spring 402 and move into the box 10. The U-shaped rod 401 is inserted into the bottom of the semi-circular plate 201. The U-shaped rod 401 blocks the rotation of the semi-circular plate 201. Through the linkage between the limiting mechanism 40 and the cover plate 204, it is ensured that the semi-circular plate 201 is firmly locked during the debridement process and will not accidentally shake or flip. The semi-circular plate 201 stably covers the top of the box 10, preventing the contaminants inside the box 10 from spreading outward, and providing medical staff with a stable contaminant receiving platform.

[0048] See Figure 1 , Figure 4 , Figure 9 and Figure 10 The support mechanism 50 includes a storage groove 501 formed at the bottom of the box 10. The storage groove 501 is symmetrically rotatably connected with support rods 502 for preventing the box 10 from tilting. Each support rod 502 has a torsion spring 505 sleeved on its rotating shaft. One end of the torsion spring 505 is fixedly connected to the support rod 502, and the other end of the torsion spring 505 is fixedly connected to the outside of the box 10.

[0049] The support mechanism 50 also includes an L-shaped limiting rod 503 that is slidably connected to the side of the housing 10 to prevent the support rod 502 from unfolding. The vertical section of the L-shaped limiting rod 503 extends into the storage groove 501, and the bottom of the L-shaped limiting rod 503 is provided with an inclined surface. The horizontal section of the L-shaped limiting rod 503 extends to the outside of the housing 10. A compression spring 504 is fixedly connected to the top of the L-shaped limiting rod 503, and the end of the compression spring 504 away from the L-shaped limiting rod 503 is fixedly connected to the housing 10.

[0050] During the actual operation, when cleaning the wound, the L-shaped limiting rod 503 is pushed upwards, causing it to disengage from the support rod 502. At this time, under the torque of the torsion spring 505, the two support rods 502 rotate 90 degrees from the storage slot 501, so that the two support rods 502 are supported on the ground. The support mechanism 50 ensures that the box 10 remains stable even on uneven outdoor ground, preventing the box 10 from tilting during subsequent cleaning operations or the movement of the flipping mechanism 20, thus avoiding the spillage of internal contaminants. When storing the support rod 502, rotate the support rod 502. The support rod 502 slides along the inclined surface at the bottom of the L-shaped limiting rod 503 into the storage groove 501. After the support rod 502 rotates into the storage groove 501, it stores the force of the torsion spring 505, providing power for the subsequent unfolding of the support rod 502. Under the elastic force of the compression spring 504, the L-shaped limiting rod 503 prevents the support rod 502 from unfolding from the storage groove 501.

[0051] Working principle:

[0052] During debridement, the support mechanism 50 ensures that the box 10 remains stable even on uneven outdoor ground. Then, the flipping mechanism 20 slides the contaminants in the semi-circular plate 201 into the box 10. At the same time, the scraping mechanism 30 ensures that the contaminants in the semi-circular plate 201 slide into the box 10. When using the semi-circular plate 201 to temporarily store contaminants, the limiting mechanism 40 prevents the semi-circular plate 201 from rotating, ensuring that the semi-circular plate 201 is firmly locked during the debridement process and will not shake or flip accidentally. The semi-circular plate 201 stably covers the top of the box 10, preventing the contaminants inside the box 10 from spreading outward, providing medical staff with a stable platform for receiving contaminants.
