Description

Technical Field

[0001] This invention belongs to the field of emergency medical equipment technology, specifically relating to a wound cleaning device for emergency patients. Background Technology

[0002] Currently, most cars lack standardized first-aid supplies and equipment. In most car accident cases, the injured do not receive on-site treatment before arriving at the hospital. Due to the harsh environment at the accident scene, wounds are exposed for a long time and are easily contaminated by bacteria, which can worsen the infection. If the wound is not cleaned in time, it may lead to uncontrollable bleeding and worsen shock. However, while existing wound cleaning devices can effectively clean the wounds, they do not fix the blood vessels, tissues, and nerves around the fracture at the scene of the accident, which can easily cause secondary damage. Furthermore, they cannot prevent the collection and containment of the flushing fluid after cleaning, which can easily lead to splashing of the flushing fluid, resulting in a large amount of blood and fluid in the treatment area and increasing the risk of contamination.

[0003] To address the aforementioned issues, this application proposes an emergency patient wound cleaning device. Summary of the Invention

[0039] 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.

[0040] Example 1

[0041] An emergency patient wound cleaning device includes a cleaning fluid tank 1, an extraction pump 2 fixed to the upper surface of the cleaning fluid tank 1, and an inlet pipe 21 fixed to the output end of the extraction pump 2. The input end of the extraction pump 2 is connected to the interior of the cleaning fluid tank 1 via a water pipe.

[0042] In this implementation plan: When a wound is exposed for a long time, it is easily contaminated by bacteria, which can aggravate wound infection. If the wound is not cleaned in time, it may cause uncontrollable bleeding and worsen shock. However, although existing patient wound cleaning devices can effectively clean patient wounds, they do not fix the blood vessels, tissues and nerves around the wound for patients with fractures at the scene of a car accident, which can easily cause secondary damage. Furthermore, they cannot block and collect the flushing fluid after cleaning, which can easily lead to splashing of the flushing fluid, resulting in a large amount of blood and fluid in the treatment area and increasing the risk of contamination of the treatment area. To solve this technical problem, a cleaning mechanism 3 has been added to this application.

[0043] like Figures 1-14 As shown:

[0044] In conjunction with the above, in order to clean the wound on the patient's leg and rinse away blood, sand, dirt, or other foreign objects inside the wound, a cleaning mechanism 3 is also included, which is installed on one side of the cleaning fluid tank 1. The cleaning mechanism 3 includes a clamping component 31, a cleaning component 32, and a suction component 33. The clamping component 31 is installed on one side of the cleaning fluid tank 1. The cleaning component 32 is installed inside the clamping component 31 near the end of the inlet pipe 21. The suction component 33 is installed inside the clamping component 31 near the side of the cleaning component 32.

[0045] In this implementation plan: the clamping component 31 can clamp and fix the patient's leg wound to prevent fractures. Insufficient fixation of the patient's leg can also prevent secondary damage to blood vessels, tissues, nerves, etc., around the wound during subsequent cleaning. The cleaning component 32 can clean the patient's leg wound, washing away blood, sand, dirt, and other foreign objects inside the wound to prevent bacterial contamination and worsening of wound infection due to prolonged exposure. The suction component 33 can quickly and evenly extract the large amount of blood and cleaning fluid generated during wound cleaning, preventing blood and cleaning fluid from splashing and contaminating the treatment area. The extracted blood and cleaning fluid are transported to the collection box 331 through the outlet pipe 3321 to collect the blood and cleaning fluid.

[0046] Furthermore:

[0047] In conjunction with the above, to clamp and fix the patient's leg wound, a clamping assembly 31 is also included. The clamping assembly 31 includes a main clamping plate 311, a secondary clamping plate 312, a pressure plate 313, a support plate 314, a fixing plate 315, a locking lug 316, a fixing frame 317, a locking rod 318, and a spring A319. A U-shaped main clamping plate 311 is fixed to one side of the cleaning fluid tank 1. U-shaped secondary clamping plates 312 are symmetrically fixed to both ends of the main clamping plate 311. The tops of both sets of secondary clamping plates 312 are hinged to pressure plates 313. The secondary clamping plates 312 and pressure plates 313... A fixing plate 315 is provided between 13, and a support plate 314 is fixed between the two sets of fixing plates 315. Locking ears 316 are symmetrically fixed on the side of the two sets of pressure plates 313 away from the cleaning fluid tank 1. An L-shaped fixing frame 317 is fixed on the side of the auxiliary clamping plate 312 near the locking ear 316. A locking rod 318 is provided inside the fixing frame 317. A locking ball head is fixed at one end of the locking rod 318 near the locking ear 316. A spring A319 is wound around the surface of the locking rod 318. The two ends of the spring A319 are respectively fixed between the fixing frame 317 and the locking ball head.

[0048] In this implementation plan: When using the emergency patient wound cleaning device, first place the patient's leg inside the main clamp 311, then hold the handle 3141 and flip the support plate 314 to move the fixing plate 315 and pressure plate 313 on the surface of the auxiliary clamp 312 until the fixing plate 315 and pressure plate 313 cover the patient's leg. During this process, the flipping of the pressure plate 313 can drive the locking ear 316 to move synchronously. The flipping of the locking ear 316 can then squeeze the locking ball head at one end of the locking rod 318, thereby squeezing the spring A319. Under the action of the fixing frame 317, the spring can... When A319 deforms and generates elasticity, when the locking ball head at one end of the locking rod 318 is aligned with the locking groove 3161, the rebound force of the locking rod 318 can engage the locking ball head at one end of the locking rod 318 into the interior of the locking groove 3161, thereby locking the locking ear 316 and the locking rod 318. This fixes the pressure plate 313 and the auxiliary clamp 312, thus clamping and fixing the patient's leg wound, preventing fractures at the wound site, ensuring the fixation of the patient's leg is not too stable, and avoiding secondary damage to the blood vessels, tissues, nerves, etc. around the wound during subsequent cleaning.

[0049] It should be noted that the inner wall of the fixing plate 315 is provided with a protective layer and has ventilation holes. Furthermore, a heating mechanism (not shown in the figure) can be installed inside the cleaning fluid tank 1 to heat the cleaning fluid inside the cleaning fluid tank 1, so that the temperature of the cleaning fluid is moderate, reducing the stimulation of the cleaning fluid on the patient's wound and thus improving the patient's comfort.

[0050] In an optional embodiment: the fixing frame 317 has a groove inside that matches the locking rod 318, and the locking rod 318 and the fixing frame 317 are slidably connected through this groove. A ring-shaped pull ring 3181 is fixed to the end of the locking rod 318 away from the locking ear 316. A locking groove 3161 that matches the locking ball head is opened inside the locking ear 316. A handle 3141 is fixed to the upper surface of the support plate 314. A threaded rod 3151 is provided on one side of the handle 3141, and the threaded rod 3151 is threadedly connected to one of the pressure plates 3. Inside 13, the threaded rod 3151 and one of the fixed plates 315 are rotatably connected by bearing A. A handwheel 3152 is fixed at one end of the threaded rod 3151 away from one of the fixed plates 315. A limit slide rod 3153 is provided on the side of the handle 3141 away from the threaded rod 3151. The limit slide rod 3153 is fixedly connected to another set of fixed plates 315. A limit slide groove adapted to the limit slide rod 3153 is opened inside the other set of pressure plates 313. The limit slide rod 3153 and the other set of pressure plates 313 are slidably connected through this limit slide groove.

[0051] In this implementation scheme: depending on the thickness of the patient's leg, rotating the handwheel 3152 can drive the threaded rod 3151 to rotate inside the pressure plate 313, thereby driving one set of fixing plates 315 to move up and down. Under the action of the support plate 314, it can drive the other set of fixing plates 315 to move synchronously, and drive the limiting slide rod 3153 to slide in the limiting slide groove opened inside the pressure plate 313, thereby clamping and fixing the wound on the patient's leg.

[0052] Furthermore:

[0053] In conjunction with the above, to clean the wound on the patient's leg and flush out blood, sand, dirt, or other foreign matter inside the wound, a cleaning assembly 32 is also included. The cleaning assembly 32 includes a liquid outlet cylinder 321, a dispensing pipe 322, a cleaning nozzle 323, an impeller 324, a drive shaft 325, a transmission cylinder 326, a support 327, a transmission rod 328, and a cover 329. The liquid outlet cylinder 321 is fixed inside the support plate 314 on the side near the inlet pipe 21. The liquid outlet cylinder 321 is connected to the inlet pipe 21, and an elliptical dispensing pipe 322 is fixed to the end of the liquid outlet cylinder 321 away from the inlet pipe 21. The surface of the dispensing pipe 322 is away from the liquid outlet. A number of cleaning nozzles 323 are fixed in an elliptical, equidistant array on one side of the cylinder 321. An impeller 324 is installed inside the liquid outlet cylinder 321. A drive shaft 325 is fixed inside the impeller 324. The end of the drive shaft 325 away from the impeller 324 is rotatably connected to a hollow transmission cylinder 326 via a bearing B. Two sets of supports 327 are symmetrically fixed on the surface of the transmission cylinder 326 and are fixed inside the liquid outlet cylinder 321. Two sets of transmission rods 328 are symmetrically rotatably connected inside the transmission cylinder 326 via a bearing C. An open-top cover 329 is installed below the support plate 314 and is fixed to the surface of the liquid outlet cylinder 321.

[0054] In this implementation scheme: the movement of the support plate 314 can drive the cover 329 to move closer to the patient's leg. When the fixing plate 315 is pressed against the patient's leg, the cover 329 will also be pressed tightly against the patient's leg. Then, the extraction pump 2 is turned on, and the extraction pump 2 extracts the cleaning liquid inside the cleaning liquid tank 1 and delivers it to the inside of the liquid outlet cylinder 321 through the liquid inlet pipe 21. Through the impact of the cleaning liquid, the impeller 324 can be driven to rotate inside the liquid outlet cylinder 321, which in turn drives the drive shaft 325 to rotate inside the transmission cylinder 326, thereby driving the transmission rod 328 to rotate synchronously. The cleaning liquid after impact will be injected into the liquid distribution pipe 322 and then sprayed out by the cleaning nozzle 323, which can clean the wound area of ​​the patient's leg, thereby washing away bloodstains, sand, dirt or other foreign objects inside the wound, preventing the wound from being exposed for a long time and causing bacterial contamination and aggravating the wound infection.

[0055] It should be noted that an atomizing mesh (not shown in the figure) can be installed inside the cleaning nozzle 323. The atomizing mesh (not shown in the figure) can make the sprayed cleaning liquid finer and gentler, and will not cause a large impact on the patient's wound due to the large water mist particles, thus avoiding secondary damage to the wound.

[0056] In an optional embodiment: bevel gears B3252 are fixed at one end of each of the two sets of transmission rods 328 near the drive shaft 325, and bevel gears A3251 are fixed at one end of the drive shaft 325 near the two sets of bevel gears B3252. Bevel gears A3251 are meshed with the two sets of bevel gears B3252. A sealing skirt 3291 is fixed at one end of the cover 329 away from the support plate 314. Several sets of marking spotlights 3292 are fixed on the lower surface of the support plate 314 near the cover 329.

[0057] In this implementation scheme: the rotation of the drive shaft 325 inside the transmission cylinder 326 can drive the bevel gear A3251 to rotate synchronously. The rotation of the bevel gear A3251 can then drive the bevel gears B3252 on both sides to rotate, which in turn drives the transmission rod 328 to rotate synchronously. By turning on the marking spotlight 3292, the marking spotlight 3292 emits positioning rays towards the patient's leg. By adjusting the position of the main clamp 311, the area of ​​the patient's wound to be cleaned is positioned directly below the cover 329.

[0058] It should be noted that the marking coverage of the marking spotlight 3292 is greater than the coverage area of ​​the cover 329, and all the electrical components involved in this application are powered by an internal power supply.

[0059] Furthermore:

[0060] In conjunction with the above, to quickly and evenly extract the large amount of blood and cleaning fluid generated during wound cleaning, a suction assembly 33 is also included. The suction assembly 33 includes a collection box 331, suction seats 332, a drive seat 333, a crankshaft 334, a rotating shaft 335, a connecting rod 336, a piston 337, a piston cylinder 338, and a suction head 339. Collection boxes 331 are symmetrically fixed to both sides of the cleaning fluid tank 1, and the collection boxes 331 are fixedly connected to the auxiliary clamping plate 312. Suction seats 332 are symmetrically fixed to both sides of the upper surface of the support plate 314. Two sets of drive seats 333 are fixed to adjacent sides of each of the two sets of suction seats 332. A crankshaft 334 is installed inside the drive seat 333. A rotating shaft 335 is fixed inside the 4, and the rotating shaft 335 is rotatably connected to the inside of the drive seat 333 via a bearing C. A connecting rod 336 is hinged inside the crank 334 via a hinge rod. The end of the connecting rod 336 away from the rotating shaft 335 passes through the surface of the suction seat 332 and extends into the inside of the suction seat 332, and is hinged to the piston 337 located inside the suction seat 332. A clearance groove adapted to the connecting rod 336 is opened inside the suction seat 332. A hollow piston cylinder 338 is fixed inside the suction seat 332 on the side near the piston 337, and the piston 337 and the piston cylinder 338 are slidably connected. Several sets of suction heads 339 are arranged in a ring array inside the cover 329.

[0061] In this implementation scheme: the rotation of the rotating shaft 335 drives the crank 334 to rotate inside the drive seat 333. The rotation of the crank 334 then drives the connecting rod 336 to reciprocate inside the suction seat 332, which in turn drives the piston 337 to reciprocate inside the piston cylinder 338. Each reciprocating motion of the piston 337 inside the piston cylinder 338 results in two suction and discharge processes. This process is repeated to quickly and evenly extract the large amount of blood and cleaning fluid generated during wound cleaning, preventing blood and cleaning fluid from splashing out and causing contamination of the treatment area. The extracted blood and cleaning fluid are transported to the collection box 331 through the discharge pipe 3321 to collect the blood and cleaning fluid.

[0062] It should be noted that: the surface of the cleaning fluid tank 1 is fixed with an injection pipe (not shown in the figure), which can be used to add cleaning fluid to the tank in advance; the surface of the collection tank 331 is fixed with a drain pipe (not shown in the figure), which can be opened to drain the fluid after cleaning is completed.

[0063] In an optional embodiment: the end of the rotating shaft 335 away from the crank 334 passes through the interior of the drive seat 333 and extends into the interior of the support plate 314, and is fixedly connected to the first gear 3351 disposed inside the support plate 314. A second gear 3352 is meshed between the two sets of first gears 3351. A transmission shaft 3353 is fixed inside the second gear 3352, and the transmission shaft 3353 is rotatably connected to the interior of the support plate 314 through the bearing D. A bevel gear C3354 is fixed on the surface of the transmission shaft 3353, and a bevel gear D3355 is fixed at the end of the transmission rod 328 near the bevel gear C3354, and the bevel gear C3354 and the bevel gear D3355 are meshed together.

[0064] In this implementation scheme: the rotation of the transmission rod 328 can drive the bevel gear D3355 to rotate synchronously, which in turn drives the bevel gear C3354 to rotate, thereby driving the transmission shaft 3353 to rotate inside the support plate 314, which in turn drives the second gear 3352 to rotate synchronously. As the second gear 3352 rotates, it can drive the first gears 3351 on both sides to rotate, which in turn drives the rotating shaft 335 to rotate synchronously.

[0065] It should be noted that the rotating shaft 335 can also be driven by a motor (not shown in the figure), thus ensuring that the fluid between the cover 329 and the patient's leg can still be extracted after cleaning stops.

[0066] In an optional embodiment: a liquid outlet pipe 3321 is fixed to the upper surface of the suction seat 332, and the end of the liquid outlet pipe 3321 away from the suction seat 332 is connected to the collection box 331. A suction pipe 3322 is fixed to the side of the surface of the suction seat 332 away from the liquid outlet pipe 3321. A ring-shaped liquid collection pipe 3323 is fixed inside the cover 329 near the suction head 339, and the end of the suction pipe 3322 away from the suction seat 332 is connected to the liquid collection pipe 3323. The two sides of the plug cylinder 338 are symmetrically fixed. There is a baffle A3381. Inside the suction seat 332, a baffle B3382 is fixed on the side near the baffle A3381. A water passage gap is formed between the baffle A3381 and the baffle B3382. A sealing plate 3383 is provided between the baffle A3381 and the baffle B3382. The sealing plate 3383 is attached to the surface of the baffle A3381 and the baffle B3382. A spring B3384 is fixed on the opposite side of the two sets of sealing plates 3383. The other end of the spring B3384 is fixedly connected to the suction seat 332.

[0067] In this implementation scheme: when the piston 337 moves to the right inside the cylinder 338, it causes the cleaning fluid inside the suction seat 332 and the cylinder 338 to move. This causes the sealing plate 3383 located on the lower left side inside the suction seat 332 to move closer to the sealing plate 3383 located on the upper left side inside the suction seat 332. This causes the cooperating spring B3384 to deform and generate elastic force, which opens the water passage gap between the baffle A3381 and the baffle B3382 located on the lower left side inside the suction seat 332. Then, the blood and cleaning fluid between the cover 329 and the patient's leg are drawn through the suction pipe 3322, the collection pipe 3323, and the suction head 339. As the piston 337 moves to the right, it causes the sealing plate 3383 located on the upper right side inside the suction seat 332 to move closer to the inside of the suction seat 332. This causes the spring B3384, which is in conjunction with the sealing plate, to deform and generate elastic force. This opens the water passage gap between the baffle A3381 and the baffle B3382 located on the upper right side inside the suction seat 332, allowing liquid to drain. Conversely, as the piston 337 moves to the left, the water passage gap between the baffle A3381 and the baffle B3382 located on the lower right side inside the suction seat 332 opens to draw in liquid, while the water passage gap between the baffle A3381 and the baffle B3382 located on the upper left side inside the suction seat 332 opens to drain liquid.

[0068] The working principle and usage process of this invention: When using this emergency patient wound cleaning device, first place the patient's leg inside the main clamp 311, then hold the handle 3141 and flip the support plate 314 to drive the fixing plate 315 and pressure plate 313 to move on the surface of the auxiliary clamp 312 until the fixing plate 315 and pressure plate 313 cover the patient's leg. During this process, the flipping of the pressure plate 313 can drive the locking ear 316 to move synchronously. The flipping of the locking ear 316 can then squeeze the locking ball head at one end of the locking rod 318, thereby squeezing the spring A319. Under the action of the fixing frame 317, the spring A319 can deform and generate elastic force. When the locking ball head at one end of the locking rod 318 is aligned with the locking groove 318... At position 161, the rebound force of the locking rod 318 allows the locking ball head at one end of the locking rod 318 to be engaged into the locking groove 3161, thereby locking the locking ear 316 and the locking rod 318, thus fixing the pressure plate 313 and the auxiliary clamp 312. Then, the marking spotlight 3292 is turned on, emitting a positioning beam towards the patient's leg. By adjusting the position of the main clamp 311 until the area of ​​the patient's wound to be cleaned is directly below the covering 329, and then, depending on the thickness of the patient's leg, rotating the handwheel 3152 causes the threaded rod 3151 to rotate inside the pressure plate 313, thereby moving one set of fixing plates 315 up and down. Under the action of the support plate 314, this allows... The other set of fixing plates 315 moves synchronously, causing the limiting slide rod 3153 to slide within the limiting groove inside the pressure plate 313, thereby clamping and fixing the wound on the patient's leg to prevent fractures. Insufficient fixation of the patient's leg also prevents secondary damage to surrounding blood vessels, tissues, and nerves during subsequent cleaning. During this process, the movement of the support plate 314 moves the cover 329 closer to the patient's leg. When the fixing plate 315 presses against the patient's leg, the cover 329 also adheres tightly to the patient's leg, and the sealing skirt 3291 ensures a seal between the cover 329 and the patient's leg. Then, the extraction pump 2 is activated to pump the cleaning fluid. The cleaning liquid inside the tank 1 is extracted and transported to the outlet cylinder 321 through the inlet pipe 21. The impact of the cleaning liquid drives the impeller 324 to rotate inside the outlet cylinder 321, which in turn drives the drive shaft 325 to rotate inside the transmission cylinder 326. This, in turn, drives the bevel gear A3251 to rotate synchronously. The rotation of bevel gear A3251 then drives the bevel gears B3252 on both sides to rotate, which in turn drives the transmission rod 328 to rotate synchronously. The rotation of the transmission rod 328 drives the bevel gear D3355 to rotate synchronously, which in turn drives the bevel gear C3354 to rotate. This, in turn, drives the transmission shaft 3353 to rotate inside the support plate 314, which in turn drives the second gear 3352 to rotate synchronously.As the second gear 3352 rotates, it drives the first gears 3351 on both sides to rotate, which in turn drives the rotating shaft 335 to rotate synchronously. The cleaning liquid after impact is injected into the separatory pipe 322 and then sprayed out by the cleaning nozzle 323 to clean the wound on the patient's leg, thereby washing away blood, sand, dirt, and other foreign objects inside the wound and preventing bacterial contamination and worsening of wound infection due to prolonged exposure. The rotation of the rotating shaft 335 drives the crank 334 to rotate inside the drive seat 333, and the rotation of the crank 334 drives the connecting rod 336 to rotate in the suction seat 33. The piston 337 reciprocates within the cylinder 338, causing it to reciprocate within the cylinder 338. When the piston 337 moves to the right within the cylinder 338, it moves the cleaning fluid within the suction seat 332 and the cylinder 338. This causes the sealing plate 3383 located on the lower left side of the suction seat 332 to move closer to the sealing plate 3383 located on the upper left side of the suction seat 332. This causes the spring B3384, which it works with, to deform and generate elastic force. This opens the water passage gap between the baffle A3381 and the baffle B3382 located on the lower left side of the suction seat 332. Furthermore, the blood and cleaning fluid between the cover 329 and the patient's leg are extracted through the suction tube 3322, the collection tube 3323, and the suction head 339. As the piston 337 moves to the right, it causes the sealing plate 3383 located on the upper right side inside the suction seat 332 to move closer to the interior of the suction seat 332. This causes the cooperating spring B3384 to deform and generate elastic force, opening the water passage gap between the baffles A3381 and B3382 located on the upper right side inside the suction seat 332, thus allowing drainage. Conversely, as the piston 337 moves to the left, the water passage gap between the baffles A3381 and B3382 located on the upper right side inside the suction seat 332... The water passage gap between the lower baffles A3381 and B3382 opens to draw in liquid, while the water passage gap between the baffles A3381 and B3382 located on the upper left side inside the suction seat 332 opens to drain liquid. The piston 337 reciprocates once inside the cylinder 338, resulting in two suction and drainage processes. This allows for the rapid and even extraction of the large amount of blood and cleaning fluid generated during wound cleaning, preventing splashing and contamination of the treatment area. The extracted blood and cleaning fluid are then transported to the collection box 331 via the outlet pipe 3321 for collection.
