Description

Technical Field

[0001] The invention relates to the field of diabetic foot wound cleaning, and in particular to a horizontal diabetic foot wound cleaning device. Background Art

[0002] Diabetic wound cleansing requires procedures like flushing with liquid medicine, negative pressure drainage, and plastic surgery, which generate significant amounts of waste fluids and solid waste. Furthermore, the patient's foot must be elevated or supported by a support device during these procedures. Traditionally, patients sit or lie down with their feet suspended in the air or supported by a stool. A waste fluid recovery bucket is then placed below the foot, and the procedures are performed above the bucket.

[0003] There are many defects when using traditional methods to clean diabetic foot wounds, which are mainly reflected in: First, the foot is suspended in the air or supported by a device, and the height of the foot cannot be adjusted during the specific operation, which brings inconvenience to the operation; second, the traditional cleaning method requires medical staff to place multiple devices around to assist in completing the cleaning operation. Negative pressure suction, liquid supply and other equipment require medical staff to adjust their positions during operation, affecting the cleaning efficiency; third, traditional cleaning methods often cause splashing and turbulence during waste liquid recovery, resulting in the inability to effectively recover the waste liquid into the waste liquid collection bucket, which has an adverse impact on the surrounding environmental hygiene and causes waste liquid pollution.

[0004] Therefore, the existing diabetic foot wound cleaning operation has defects such as inconvenient operation and incomplete waste liquid recovery. These defects affect the efficiency of the cleaning operation. There is an urgent need to provide a horizontal diabetic foot wound cleaning device that can improve operational efficiency, prevent waste liquid pollution during the operation process, and at the same time has a high degree of integration and is easy to operate.

[0029] like Figure 1 、 2 As shown in Figures 3, 4, 5, 6 and 7, a horizontal diabetic foot wound cleaning device comprises a support frame 1, a back support plate 3 is fixedly mounted on the top of the front side of the support frame 1, a leg adaptive support lifting device is mounted on the top of the support frame 1 on the rear side of the back support plate 3, an operating table 10 is fixedly mounted on the rear end of the support frame 1, a retractable liquid supply nozzle 13 and a retractable negative pressure suction joint 15 are mounted on the operating table 10, a waste liquid pool 20 matched with the rear end of the leg adaptive support lifting device is mounted on the front side of the bottom of the operating table 10, a small hydraulic station 24 is arranged at the front end of the waste liquid pool 20, a support rod 29 is mounted in the support frame on the rear side of the back support plate 3, a hydraulic rod 30 connected to the small hydraulic station 24 is mounted on the support rod 29, and the output end of the hydraulic rod 30 is connected to the bottom of the front end of the leg adaptive support lifting device. The leg adaptive support lifting device includes a lifting plate 4 connected to the rear side of the back support plate 3 through a first rotating connector 5, the lifting plate 4 is connected to the knee joint support block 6 through a second rotating connector 7, and the knee joint support block 6 is connected to the linkage support plate 9 through a third rotating connector 8. The linkage support plate 9 is provided with a foot placement slot 18 that matches the top of the waste liquid pool 20, and the middle part of the bottom surface of the lifting plate 4 is hinged to the output end of the hydraulic rod 30.

[0030] Specifically, this product adopts a combined structure of a support frame 1 and an operating table 10. The combined structure is an integral support surface for horizontal operations. The top of the back support plate 3 is the patient's back-bearing part when in use, and an armrest 2 can be added on its upper part. The top surface of the support frame 1 on the rear side of the back support plate 3 is a hollow structure, and the leg adaptive support lifting device is installed on the upper part of the hollow structure. The retractable liquid supply nozzle 13 and the retractable negative pressure suction joint 15 are installed on the top of the operating table 10 and distributed on both sides of the center position of the operating table 10, which is convenient for medical staff to operate with both hands. The top surface of the waste liquid pool 20 corresponds to the foot placement slot 18 in the initial state and after the position is changed. During operation, it is ensured that the waste liquid can flow from the feet into the waste liquid pool 20.

[0031] The lifting plate 4, the knee joint support block 6 and the linkage support plate 9 are all connected by a rotating connector. After the output at the top of the hydraulic rod 30, the output end force acts on the bottom surface of the lifting plate 4. The connection position of the lifting plate 4 and the back support plate 3 is in a rotating connection state. When the hydraulic rod 30 continues to output, the lifting plate 4 rotates around the rear end of the back support plate 3. During the rotation process, the knee joint support block 6 and the linkage support plate 9 are displaced accordingly. Under the support of the hydraulic rod 30, the knee joint support block 6 supports the knee joint area, and the linkage support plate 9 supports the calf area with the slotted area. The foot is freely supported in the foot placement slot 18. After the foot is adjusted in height as required, its working surface faces the front side of the operating table 10, which can correspond to the operator's operating position. In addition, during the process of cleaning the foot wound, the operator can adjust the foot position of the operating surface in real time according to the needs, including height, angle, etc.

[0032] An opening and closing door 11 is provided on the rear side of the operating table 10, and storage drawers 12 are symmetrically installed on both sides of the upper part of the opening and closing door 11. A liquid medicine tank 31 and a suction storage tank 37 are installed in the operating table 10. A first plug-in hole 26 and a second plug-in hole 25 are provided on the top surface of the operating table 10. The pull-out liquid supply nozzle 13 and the pull-out negative pressure suction joint 15 are respectively installed in the first plug-in hole 26 and the second plug-in hole 25. A liquid pump 32 is provided on the top of the liquid medicine tank 31, and the liquid pump 32 is connected to the pull-out liquid supply nozzle 13 through an elastic hose installed in the first plug-in hole 26. One side of the top of the suction storage tank 37 is connected to the pull-out negative pressure suction joint 15 through an elastic hose installed in the second plug-in hole 25, and the other side of the top of the suction storage tank 37 is connected to the negative pressure suction machine 36 through a pipeline.

[0033] Specifically, the operating table 10 is equipped with an opening and closing door 11 to facilitate the taking and placing of the liquid medicine tank 31 and the suction storage tank 37. The installation of the storage drawer 12 can provide the medical staff with access to stored items within the radiation range of the left and right hands during operation, which increases the practicality of the product, improves the space utilization rate, and facilitates the collection of items during operation. The liquid medicine tank 31 is filled with medicine for disinfection, anti-inflammatory and other needs. When the liquid pump 32 is turned on, the liquid medicine is transported through a pipe to the retractable liquid supply nozzle 13 and sprayed on the wound surface of the foot. The suction storage tank 37 is used to store the suction waste. When the negative pressure suction machine 36 is turned on, the waste on the surface of the foot sucked by the retractable negative pressure suction connector 15 is transported through a pipe to the suction storage tank 37. The medicine liquid tank 31 and the suction storage tank 37 are both located in the inner cavity of the operating table 10. The retractable liquid supply nozzle 13 and the retractable negative pressure suction connector 15 are installed on the top of the operating table 10 in a plug-in manner, and are connected to the corresponding tank bodies through pipes respectively, which can provide flexible operating space for the wound position during operation.

[0034] A first electric controller 33 and a second electric controller 34 are installed in the operating table 10. The first electric controller 33 is connected to the liquid supply switch 14 installed on the side of the retractable liquid supply nozzle 13. The second electric controller 34 is connected to the negative pressure suction switch 16 installed on the side of the retractable negative pressure suction joint 15. A hydraulic control switch 17 connected to the small hydraulic station 24 is provided on the side of the negative pressure suction switch 16. A hot air blower 35 is installed under the top plate of the operating table 10. The output end of the hot air blower 35 is connected to the air distribution box 19. The outer end of the air distribution box 19 is set at the front end of the top of the operating table 10. An air outlet 38 facing the front end of the support frame 1 is opened on the air distribution box 19. The air outlet 38 is a triangular slot structure that is inclined at an angle of 45 degrees to the horizontal plane and discharges air downward. A hot air blower switch 39 connected to the hot air blower 35 is provided on the top surface of the operating table 10. The waste liquid pool 20 and the small hydraulic station 24 are fixedly supported by a support frame 23 below, the rear end of the support frame 23 is fixedly connected to the bottom of the front end of the operating table 10, and a drain pipe 22 with a drain valve is provided at the bottom of the waste liquid pool 20.

[0035] Specifically, the electronic control part of this product is also located in the inner cavity of the operating table 10. The liquid supply, negative pressure suction, and hydraulic control are all located on the top surface of the operating table 10 for easy control. A hot air blower 35 is also configured. Hot air can be blown out through the triangular slot structure air outlet 38 set at the front, which is tilted at a 45-degree angle to the horizontal plane and blows out air downward. Hot air is applied to the feet after the liquid medicine is sprayed, thereby improving the efficiency of the cleaning operation. The outlet position of the air distribution box 19 corresponds to the placement position of the feet. It does not adopt the method of induced air outlet at 45 degrees downward. It prevents the environmental pollution caused by the splashing of excess liquid medicine during the hot air drying process and ensures that the waste liquid can be efficiently recovered into the waste liquid pool 20.

[0036] The lifting plate 4 is a square plate-like structure, the length of which is equal to the width of the support frame 1, and the lifting plate 4 is arranged on the top surface of the support frame 1. The knee joint support block 6 is a cylindrical structure with a curved top surface, and the knee joint support block 6 is arranged on the top surface of the support frame 1, and the length of the knee joint support block 6 is equal to the width of the support frame 1. The length of the linkage support plate 9 is equal to the width of the support frame 1, and the foot placement slot 18 extends from the rear end of the linkage support plate 9 to the front terminal position. The length of the foot placement slot 18 is no greater than the length of the waste liquid tank 20, and the width of the foot placement slot 18 is no greater than the width of the waste liquid tank 20. The waste liquid tank 20 is a trough-like structure with an opening at the top, and a perforated filter screen 21 is arranged in the middle of the waste liquid tank 20. Two sliding protrusions 28 are symmetrically installed below the linkage support plate 9, and a limiting guide groove 27 for installing the sliding protrusions 28 is provided at the top of the support frame 1.

[0037] Specifically, in order to improve the stability of the product during operation, a protrusion 28 is installed at the bottom of the linkage support plate 9 of this product. The protrusion 28 is located in the limiting guide slot 27. When the linkage support plate 9 is displaced along with the knee joint support block 6 and the lifting plate 4, the mutual limiting effect of the protrusion 28 and the limiting guide slot 27 ensures the stability of the linkage support plate 9 during operation, thereby achieving stable support during the change of the patient's leg position.

[0038] During the specific operation of the present invention, in the initial state, the lifting plate 4, the knee joint support block 6 and the linkage support plate 9 are all in a horizontal support state, so that the patient lies flat on the lifting plate 4, the knee joint support block 6, the linkage support plate 9 and the back support plate 3 in a supine position, with the patient's feet facing the operating table 10. After the supine position is prepared, the foot wound cleaning operation begins.

[0039] During the cleaning process, the medical staff first observes the location of the patient's foot wound. When the patient's foot wound is located at the toe position, the wound can be cleaned by lying down, and the output operation of the hydraulic rod 30 is not required at this time. The medical staff selects the retractable liquid supply nozzle 13 or the retractable negative pressure suction joint 15 or uses the retractable liquid supply nozzle 13 and the retractable negative pressure suction joint 15 at the same time to clean the patient's foot wound. During the cleaning process, after the liquid supply switch 14 is turned on, the liquid pump 32 starts to pump liquid, and the liquid in the liquid tank 31 is transported to the retractable liquid supply nozzle 13 through the pipeline. The retractable liquid supply nozzle 13 is held by the hand to spray the liquid at a fixed point on the foot wound. When the negative pressure suction switch 16 is turned on, the negative pressure suction machine 36 operates, sucking out the air from the suction storage tank 37. Simultaneously, the pipe connecting the suction storage tank 37 and the retractable negative pressure suction connector 15 performs the suction operation. The retractable negative pressure suction connector 15 is held in hand to suction foreign matter from a specific location. During operation, excess waste liquid is recovered into the waste liquid reservoir, and the open space of the foot placement slot 18 does not obstruct the waste liquid recovery.

[0040] When the patient's foot wound is located on the sole or top of the foot, the output control of the hydraulic rod 30 is required to achieve support for the patient's leg position change. When the hydraulic control switch 17 is turned on, the output end of the hydraulic rod 30 performs an ejection operation on the lifting plate 4. The bottom of the hydraulic rod 30 is connected to the support rod 29 via a hinged connection. The bottom of the lifting plate 4 is also connected to the output end of the hydraulic rod 30 via a hinged connection. When the hydraulic rod 30 output operation is in operation, the lifting plate 4 rotates around the rear end of the back support plate 3, driving the knee joint support block 6 to rise during this rotation. The bottom of the rear end of the linkage support plate 9 is limited by the interaction between the sliding protrusion 28 and the limiting guide groove 27. The rear end of the linkage support plate 9 moves toward the position of the back support plate 3 during the raising of the knee joint support block 6. The lifting plate 4, knee joint support block 6, and linkage support plate 9 form an inverted V-shaped structure. The patient is in a prone position with knees bent, and the foot is now elevated and supported. The control of the hydraulic rod 30 can adjust the height and front-back position of the foot.

[0041] After completing the foot position adjustment operation, the medical staff selects the retractable liquid supply nozzle 13 or the retractable negative pressure suction connector 15 or uses the retractable liquid supply nozzle 13 and the retractable negative pressure suction connector 15 at the same time to perform wound cleaning operations on the patient's foot. During the cleaning operation, after turning on the liquid supply switch 14, the liquid pump 32 operates to extract liquid, and the liquid in the liquid tank 31 is transported to the retractable liquid supply nozzle 13 through the pipeline. The retractable liquid supply nozzle 13 is held by hand to perform a fixed-point liquid spraying operation on the foot wound. When the negative pressure suction switch 16 is turned on, the negative pressure suction machine 36 operates, and the air in the suction storage tank 37 is sucked out. At the same time, the pipeline connecting the suction storage tank 37 and the retractable negative pressure suction connector 15 performs a suction operation. The retractable negative pressure suction connector 15 is held by hand to perform suction on foreign objects in a specific position. During operation, excess waste liquid is recovered downwardly into the waste liquid pool, and the open space of the foot placement slot 18 will not hinder the waste liquid recovery.

[0042] When performing operations in the above two positions, after completing the foot wound cleaning operation, the hot air blower switch 39 is turned on, and the hot air blower 35 starts to work. Hot air is blown out from the air outlet 38 of the triangular slot structure arranged on the air distribution box 19, which is inclined at an angle of 45 degrees to the horizontal plane and discharges air downward. The hot air blowing and drying operation is performed on the feet of the patient who is lying flat or lying flat with the knees bent after adjustment, to ensure the dryness of the feet, and the excess waste liquid is recovered into the waste liquid pool 20.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
