Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a limb debridement device. Background Technology

[0002] Wound debridement is a treatment measure that removes dead tissue, blood clots, foreign bodies, and other harmful substances from wounds or lesions. It is of great significance for softening blood crusts at the wound site, thereby more effectively cleaning the wound, improving local blood circulation, promoting the repair of damaged tissues, and reducing pain. By rinsing open wounds or lesions with a medicated solution (usually physiological saline), dirt is removed, blood clots and foreign bodies are eliminated, and the wound or lesion is prevented from being contaminated, creating favorable conditions for healing and improving the recovery speed.

[0003] During limb debridement, the affected limb is typically placed on a debridement cart to assist doctors in rinsing the wound or lesion surface. (The debridement cart used by the inventor's unit is a trolley with casters at the bottom, a funnel fixed to the bottom of the top plate, and a trash can placed inside, with the funnel's outlet aligned with the trash can; the saline bag used for debridement is suspended on the cart, and the saline bag includes a saline reservoir, an irrigation tube, and a drip chamber and flow controller attached to the irrigation tube.) During the debridement process, medical personnel need to stably position the patient's affected limb on the debridement cart in a suitable position (e.g., height and angle) to facilitate the debridement operation and the collection of debridement waste. However, the aforementioned debridement cart lacks components for supporting, limiting, and adjusting the limb, making it inconvenient for the stable placement and flexible adjustment of the patient's limb. Furthermore, the overall height of the cart is fixed, and the limb height cannot be adjusted as needed; for example, the support height of the limb is obviously different when debridement of the upper limb and the lower limb. Therefore, there is an urgent need for a limb debridement cart with limb support, limiting, and adjustment components to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the background art and to provide a limb debridement device that can support, limit and adjust the affected limb in limb debridement engineering.

[0005] The present invention adopts the following technical solution: a limb debridement device, including a debridement trolley, a collection tank and a support assembly. The debridement trolley includes a panel and a collection basin. A through groove is opened in the middle of the panel. The collection basin is fixedly installed on the bottom surface of the panel. The top opening of the collection basin is connected to the through groove. The collection tank is placed inside the debridement trolley. The outlet of the collection basin is connected to the inlet of the collection tank.

[0006] The support assembly includes a support block and a height adjustment component. The bottom end of the height adjustment component is fixedly installed on one side of the top surface of the panel, and the top end is connected to the support block through a universal adjustment component. The patient's affected limb is supported on the support block. The height adjustment component is used to adjust the support height of the support block, and the support block adjusts the support angle through the universal adjustment component.

[0007] Furthermore, the height adjustment component includes a sleeve, a telescopic rod, and a pin. The bottom end of the sleeve is fixedly installed on one side of the top surface of the panel. The top end of the telescopic rod is connected to the support block through a universal adjustment component. A socket is opened perpendicular to the sleeve, and at least two adjustment holes are opened at equal intervals along the length of the telescopic rod. The telescopic rod is sleeved inside the sleeve and can move vertically along the sleeve. When the socket is aligned with the adjustment hole at the target position, the pin is used to pass through the socket and the adjustment hole to fix the support height of the support block.

[0008] Furthermore, the universal adjustment component includes a universal ball fixed to the top of the height adjustment component and a ball groove formed on the bottom surface of the support block. The universal ball is matched and installed in the ball groove, so that the support block can rotate around the universal ball to adjust the support angle of the support block.

[0009] Furthermore, the support block is made entirely of a rigid material, and a limiting groove is formed on the top surface of the support block, with a flexible pad layer laid on the limiting groove.

[0010] Furthermore, the support block extends towards one end of the through slot to directly above the through slot.

[0011] Furthermore, the debridement trolley also includes a base plate, support rods, bracket, hooks, and casters. The four support rods are upright and fixed on the base plate. The panel is fixedly installed on the top of the four support rods. The four casters are fixedly installed on the bottom surface of the base plate. The collection tank is installed on the base plate. The bracket is upright and fixedly installed on one side of the top surface of the panel. At least one hook is fixedly installed on the top of the bracket.

[0012] Furthermore, the limb debridement device also includes a heating component, which includes a heating sleeve, a hanging ring, and a power cord. The hanging ring is fixed to the top of the heating sleeve. The heating sleeve consists of a heat-conducting layer, a heating layer, and a heat-insulating layer from the inside out. Heating wires are evenly laid in the heating layer. The power cord is electrically connected to the heating wires. Velcro fasteners that can be stuck together are provided at both ends of the heating sleeve.

[0013] Furthermore, the heating layer is filled with asbestos or glass fiber, the insulation layer is made of foam board, and the heat-conducting layer is made of aluminum foil. A temperature controller is also connected to the power cord to set the heating constant temperature.

[0014] Furthermore, the heating component also includes an airbag layer, an air tube, and a balloon. The airbag layer is fixedly wrapped around the outside of the insulation layer. One end of the air tube is connected to the airbag layer, and the other end is connected to the balloon. The balloon is used to inflate and deflate the airbag layer.

[0015] The limb debridement device of this invention supports the affected limb on a support block, and the support angle of the affected limb can be adjusted by a height adjustment component and a universal adjustment component, so as to achieve stable placement of the affected limb and flexible adjustment to a suitable position, which facilitates the debridement operation of medical staff and the collection of debridement waste fluid. The saline bag is hung on a hook, and medical staff can rinse the wound by pointing the end of the irrigation tube at the wound or lesion. The waste fluid, blood clots and foreign objects after rinsing enter the collection basin and are finally discharged into the collection bucket for subsequent centralized treatment. At the same time, the heating component is wrapped around the saline bag to heat the saline at a constant temperature, preventing the patient from hypothermia, local vasoconstriction and slowed blood flow, which are not conducive to wound cleaning and healing. The air bladder layer can keep the heating component in close contact with the saline bag to ensure the heating and constant temperature effect. At the same time, the saline bag can be inflated and pressurized to promote the rapid discharge of saline. Attached Figure Description

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. The invention will be further described below in conjunction with the drawings:

[0024] Example 1

[0025] Refer to the instruction manual appendix Figure 1 A limb debridement device includes a debridement cart 1, a collection tank 2, and a support assembly 3.

[0026] Refer to the instruction manual appendix Figure 2 The cleaning cart 1 includes a panel 11, a base plate 12, a support rod 13, a collection basin 14, a bracket 16, a hook 17, casters 18, and a sleeve 19. The panel 11, base plate 12, support rod 13, collection basin 14, bracket 16, hook 17, and sleeve 19 can be made of stainless steel and are connected and fixed by welding or screws. The whole is stable and durable, and easy to clean and disinfect.

[0027] Four support rods 13 are upright and fixed to the top surface of the base plate 12. The panel 11 is fixedly installed on the top of the four support rods 13. Four casters are fixedly installed on the bottom surface of the base plate 12. A through groove is opened in the middle of the panel 11. The collection basin 14 is fixedly installed on the bottom surface of the panel 11. The bottom surface of the collection basin 14 is closed and the top surface is open. The opening on the top surface of the collection basin 14 is connected to the through groove. An outlet 15 is opened on the bottom surface of the collection basin 14. The collection bucket 2 is placed on the base plate 12 (a groove is provided on the top surface of the base plate 12, and the bottom end of the collection bucket 2 is placed in the groove to prevent the collection bucket 2 from shifting or even slipping off the base plate 12 when the cleaning cart 1 moves). The collection bucket 2 is wrapped with... The container includes a barrel body and a lid. A liquid inlet is provided at the top of the lid. A drain pipe with a switch is connected to the lower part of the barrel body. A corrugated pipe is fixedly connected to the outlet 15 of the collection basin 14. The other end of the corrugated pipe extends from the liquid inlet into the collection barrel 2. A bracket 16 is vertically and fixedly installed on one side of the top surface of the panel 11. The bracket 16 includes two uprights and a crossbar fixedly connected to the top of the two uprights. Three hooks 17 are fixedly installed at equal intervals on the crossbar of the bracket 16. A sleeve 19 is fixedly installed on the top surface of the panel 11 (e.g., by welding) on ​​the side opposite to the bracket 16. A horizontal insertion hole 191 is provided on the sleeve 19.

[0028] Refer to the instruction manual appendix Figure 3 , 4 The support component 3 includes a support block 31, a telescopic rod 32, a pin 33, and a universal ball 34. The support block 31 is made of a rigid material (such as rigid plastic). A limiting groove 311 is formed on the top surface of the support block 31. The limiting groove 311 is U-shaped and is a through groove in the front and back direction. The limiting groove 311 facilitates the stable support of the limb on the support block 31 and prevents the limb from slipping. A flexible padding layer (such as a silicone padding layer, a foam padding layer, and a gel padding layer) is laid on the limiting groove 311 to make the limb flexibly contact the support block 31 and increase comfort.

[0029] Four adjustment holes 321 are equally spaced along the length of the telescopic rod 32. The telescopic rod 32 is sleeved in the sleeve 19 and can move vertically along the sleeve 19. When the insertion hole 191 is aligned with the adjustment hole 321 at the target position or target height, the pin 33 is passed through the insertion hole 191 and the adjustment hole 321 to fix the support height of the support block 31. The universal ball 34 is fixed to one end of the telescopic rod 32. A ball groove 312 is opened on the bottom surface of the support block 31. The universal ball 34 is matched and installed in the ball groove 312, so that the support block 31 can rotate around the universal ball 34 to adjust the support angle of the support block 31. The ideal support height and angle are: after adjusting and fixing the support height of the support block 31 according to the patient's position, the limb is tilted and supported on the support block 31, and the end of the limb extending towards the collection basin 14 is the lower end, which can ensure that the saline for debridement and irrigation flows into the collection basin 14 along the limb.

[0030] When a limb is supported on the support block 31 and the wound or lesion is close to the support block 31, some saline solution may be flushed onto the support block 31 or flow down the limb onto the support block 31 during saline irrigation. In order to ensure that the saline solution on the support block 31 flows into the collection basin 14 and does not flow outside the debridement cart 1, the end of the support block 31 facing the through groove extends to the top of the through groove. Since the support block 31 is also in an inclined state after supporting the limb, and the side facing the collection basin 14 is the lower end, the saline solution on the support block 31 will drip down the support block 31 into the collection basin 14.

[0031] The method of using the limb debridement device in this embodiment 1 is as follows: Before the debridement operation begins, the saline bag is suspended on the hook 17. The patient abducts and opens the affected limb at a suitable angle. The angle of the support block 31 is rotated to support the patient's affected limb in the limiting groove 311 of the support block 31 (the upper limb is supported at the elbow joint or the upper arm above the elbow joint, and the lower limb is supported at the knee joint or the thigh above the knee joint). The height of the support block 31 is adjusted by the sleeve 19, the telescopic rod 32, and the pin 33 to make the patient's affected limb in a suitable position and to make the limb tilted and supported on the support block 31, with the end of the limb extending towards the collection basin 14 being the lower end. Medical staff can then hold the irrigation tube to perform debridement and irrigation operations on the wound or wound surface, and the flow rate of the saline can be controlled by the flow controller. The generated irrigation waste enters the collection basin 14 and enters the collection bucket 2 in sequence through the outlet 15, the corrugated pipe, and the inlet for subsequent centralized treatment.

[0032] Example 2

[0033] The inventors discovered that in seasons or environments with lower temperatures, the temperature of saline solution used for wound cleaning and rinsing is also lower. If saline solution with a lower temperature is used directly to clean and rinse wounds or lesions, it may cause hypothermia in patients, and may also cause local vasoconstriction, slowing blood flow, which is not conducive to wound cleaning and healing. In fact, the lower temperature of saline solution may even cause cold stimulation to patients, causing them to move or retract their limbs due to physical reflexes, which makes wound cleaning inconvenient.

[0034] Therefore, in view of the above problems, based on Embodiment 1 and referring to the appendix of the specification, Figure 1 A limb debridement device includes a debridement cart 1, a collection tank 2, a support component 3, and a heating component 4.

[0035] Refer to the instruction manual appendix Figure 5 , 6The heating component 4 includes a heating sleeve 41, a hanging ring 42, and a power cord 43. The hanging ring 42 is fixed to the top of the heating sleeve 41. The heating sleeve 41 can be hung on the hook 17 through the hanging ring 42. Velcro 415 that can be stuck together are provided at the left and right ends of the heating sleeve 41. After the heating sleeve 41 is wrapped around the outside of the saline bag, the left and right ends of the heating sleeve 41 are connected by the Velcro 415 to ensure that the heating sleeve 41 and the saline bag fit tightly.

[0036] The heating jacket 41 consists of a heat-conducting layer 411, a heating layer 412, and an insulation layer 413 from the inside out. Heating wires are evenly laid inside the heating layer 412, and asbestos or glass fiber is also filled inside the heating layer 412. After the heating wires are heated, the heat is transferred to the asbestos or glass fiber for heat preservation. The insulation layer 413 can be a foam board, which has good heat preservation effect, low price, and light weight. The heat-conducting layer 411 can be made of aluminum foil, which can make the heat conduction more even. The power cord 43 is electrically connected to the heating wires, and the other end of the power cord 43 can be connected to a power bank. A pocket for placing a power bank can be provided on the outside of the heating jacket 41 for convenient use. A temperature controller is also connected to the power cord 43 to set the heating constant temperature (e.g., 35~42 degrees).

[0037] The inventors also discovered that as saline solution is used for wound cleaning, the saline bag will gradually deflate from being full, causing the heating sleeve 41 to not fit tightly with the saline bag, and even to detach in some places, affecting the heating and heat preservation effect.

[0038] Therefore, in response to the above problems, please refer to the appendix to the instruction manual. Figure 5 , 6 The heating component 4 also includes an airbag layer 414, a trachea 44, and a balloon 45. The airbag layer 414 is fixedly wrapped around the outside of the insulation layer 413. One end of the trachea 44 is connected to the airbag layer 414, and the other end is connected to the balloon 45. The balloon 45 is used to inflate and deflate the airbag layer 414. The function of the balloon 45 is similar to that of the balloon on a manual blood pressure monitor. By squeezing the balloon 45, the airbag layer 414 is inflated, thereby achieving close contact between the heating sleeve 41 and the saline bag and squeezing the saline bag. On the one hand, it can make the heating component fit tightly against the saline bag to ensure the heating and constant temperature effect. On the other hand, it can also inflate and pressurize the saline bag to promote the rapid discharge of saline and ensure the flushing effect. A knob switch is also provided at the connection section between the balloon 45 and the trachea 44 to switch between deflation and inflation.

[0039] The method of using the limb debridement device in this embodiment 2 is as follows: Before the debridement operation begins, hang the saline bag on the hook 17, hang the ring 42 on the hook 17, and wrap the heating sleeve 41 around the outside of the saline bag. Then, connect the left and right ends of the heating sleeve 41 with Velcro 415 to ensure that the heating sleeve 41 is tightly attached to the saline bag. Set the heating constant temperature through the temperature controller.

[0040] The patient abducts and opens the affected limb at a suitable angle. The angle of the support block 31 is rotated to support the patient's affected limb within the limiting groove 311 of the support block 31 (upper limb supported at or above the elbow joint, lower limb supported at or above the knee joint). The height of the support block 31 is adjusted using the sleeve 19, telescopic rod 32, and pin 33 to position the patient's affected limb appropriately, ensuring the limb is tilted and supported on the support block 31, with the end of the limb extending towards the collection basin 14 being the lower end. After the saline solution is heated to the target temperature, medical staff... The handheld irrigation tube can be used to clean and irrigate wounds or lesions. The flow rate of saline can be controlled by a flow controller. During the cleaning and irrigating process, medical staff can inflate the airbag layer 414 by squeezing the balloon 45, thereby achieving close contact between the heating sleeve 41 and the saline bag and squeezing the saline bag, ensuring the heating and constant temperature effect of the saline and the irrigating effect. The generated irrigating waste liquid enters the collection basin 14 and enters the collection bucket 2 in sequence through the outlet 15, the corrugated pipe, and the inlet for subsequent centralized treatment.

[0041] Obviously, modifications and / or additions can be made to the above-mentioned limb debridement device and corresponding methods without departing from the field and scope of this utility model.

[0042] It is equally clear that, although this invention has described the limb debridement device in detail, those skilled in the art will certainly be able to obtain many other equivalent forms of limb debridement devices and corresponding methods, which have the features described in the claims and are therefore within the scope of protection defined herein.
