Description

Technical Field

[0001] The present invention relates to the technical field of dressing change racks, and specifically to a dressing change rack for diabetic foot. Background Art

[0002] When dressing a diabetic foot, a special dressing change rack is used. The patient's leg is placed on the dressing change rack to support the leg, so that medical staff can easily dispose of the foot wound.

[0003] Chinese Patent No. 202210681357.5 discloses "a dressing change device for diabetic foot". Under the coordinated action of the medicine application mechanism, the mixing mechanism and the reciprocating mechanism, the medicine storage barrel can be driven to move up and down in a cyclic reciprocating manner while the mixing blades rotate, so that the medicine liquid can be quickly and fully mixed, and the fully mixed medicine liquid can be evenly sprayed on the appropriate position of the patient's foot, thereby effectively improving the treatment effect.

[0004] However, during the use of this device, the medicine application mechanism is in an open state and directly exposed to the air. In scenarios where air circulation is poor, disinfection measures are not in place or environmental pollution is relatively serious (such as a temporarily built field hospital, an emergency scene, a dressing change room in an old hospital, etc.), viruses, bacteria or tiny particulate impurities in the air will enter the patient's wound through the atomizing nozzle or the medicine delivery hose, causing secondary infection. Since diabetic foot patients have poor local blood circulation and low immune function, wound infection is likely to lead to delayed healing, and in severe cases, it may cause cellulitis, sepsis, and even require amputation.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a dressing change rack for diabetic foot, having the following beneficial effects:

[0019] 1. For this dressing change rack for diabetic foot, with the setting of the positive pressure mechanism, the hot air in the top support column will also enter the sandwich cavity through the through pipe and then be output and blown through the annular exhaust port, so as to form a positive pressure environment in the spherical bin, thereby preventing pollutants in the external air from entering the spherical bin, maintaining the cleanliness and sterility of the treatment area, and improving the safety of treatment or operation.

[0020] 2. For this dressing change rack for diabetic foot, with the setting of the positive pressure mechanism, the hot air will pass through the hollow interior of the U-shaped footrest, heating the U-shaped footrest, which helps to warm the surrounding environment and directly improve the comfort of the user. Especially when used in a cold environment, through the dissipation of the hot air, a warm experience can be provided.

[0021] 3. For this dressing change rack for diabetic foot, with the setting of the homogeneous feeding mechanism, when the water pump sucks liquid through the hollow annular part and the oblique liquid inlet, a reverse acting force will be generated when sucking liquid through the oblique liquid inlet to drive the hollow annular part to rotate, so that the oblique liquid inlet rotates to absorb the liquid medicine. Rotary liquid absorption can make the surrounding liquid medicine flow more evenly, reduce precipitation, ensure the stability of the concentration of the inhaled liquid medicine. At the same time, the hollow annular part drives the fan blades to rotate, stirring the liquid medicine, which can further enhance the uniformity of the liquid medicine, avoid liquid medicine precipitation, improve the liquid absorption efficiency, and ensure the stability of the concentration of the sprayed or transported liquid medicine, thereby improving the treatment effect. The liquid medicine output by the output end of the water pump is output and sprayed through the connecting column, the arc-shaped connecting part and the nozzle.

[0022] 4. The dressing change rack for diabetic foot uses a circulating mechanism. When the stepper motor is turned on, it drives the half gear to rotate. The half gear drives the main gear to rotate, the main gear drives the secondary gear to rotate, and the secondary gear drives the volute spring to store energy. The main gear drives the connecting column, the arc-shaped connecting piece, and the nozzle to rotate. After the arc-shaped connecting piece rotates to the other side of the top support column, the toothless part of the half gear rotates to one side of the main gear, so that the half gear no longer meshes with the main gear at this time. At this time, the volute spring releases and drives the secondary gear to rotate, and the secondary gear drives the main gear to reverse and return to its original position until the toothed part of the half gear continues to mesh and drives the main gear to rotate. This cycle repeats, causing the nozzle to rotate back and forth in a cyclic manner for spraying, enabling the liquid medicine to evenly cover the target area, improving the uniformity of spraying and the treatment effect, and at the same time avoiding the problem of uneven coverage caused by a fixed spraying angle, thereby enhancing the utilization rate of the liquid medicine and the treatment efficiency.

The electric fan 38 is responsible for outputting the heated air. A temperature sensor 310 is fixedly connected to the top of the electric fan 38. The temperature sensor 310 is connected to the heating device 39 through a signal line. The temperature sensor 310 is used to monitor the air temperature in real time and feedback it to the heating device 39, so that the heating device 39 adjusts the heating intensity according to the feedback of the temperature sensor 310 to ensure that the output air temperature always remains within the set safe range. A footrest exhaust port 311 is arranged at the bottom of the U-shaped footrest 33, so that the output hot air can be discharged through the footrest exhaust port 311, which means that the hollow interior of the U-shaped footrest 33 will pass through hot air to heat the U-shaped footrest 33, which helps to warm the surrounding environment and directly improves the comfort of the user. Especially when used in a cold environment, through the dissipation of hot air, a warm experience can be provided. The seal cover 34 is fixedly connected to the bottom support column 31 by bolts.

A water pump 43 is fixedly connected to the inner wall of the medicine storage device 41. The output end of the water pump 43 is rotationally connected to a communicating column 44. An arc-shaped communicating part 45 is fixedly connected to the inner wall of the communicating column 44. A spray head 46 is arranged on the arc-shaped communicating part 45. A compression spring 47 is arranged on the inner wall of the medicine storage device 41. One end of the compression spring 47 is fixedly connected to the inner wall of the medicine storage device 41, and the other end of the compression spring 47 is fixedly connected to a sealing disc 48. A guiding column 49 is fixedly connected to the outer wall of the sealing disc 48. The outer wall of the guiding column 49 is slidably connected to the inner wall of the medicine storage device 41. The outer wall of the sealing disc 48 is in piston connection with the inner wall of the medicine storage device 41. When it is necessary to fill the liquid medicine, the liquid medicine is input into the medicine storage device 41 through the medicine inlet 42 by using high pressure. At this time, the sealing disc 48 in the medicine storage device 41 is extruded, so that the sealing disc 48 drives the compression spring 47 to be compressed. The input end of the water pump 43 is rotationally connected to a hollow ring 410. An inclined liquid inlet 411 is fixedly connected to the inner wall of the hollow ring 410. A fan blade 412 is fixedly connected to the hollow ring 410. When the water pump 43 sucks liquid through the hollow ring 410 and the inclined liquid inlet 411, a reverse acting force will be generated when the inclined liquid inlet 411 sucks liquid, driving the hollow ring 410 to rotate, so that the inclined liquid inlet 411 rotates to absorb the liquid medicine. Rotational liquid absorption can make the surrounding liquid medicine flow more evenly, reduce precipitation, ensure the stability of the concentration of the inhaled liquid medicine. At the same time, the hollow ring 410 drives the fan blade 412 to rotate, stirring the liquid medicine, which can further enhance the uniformity of the liquid medicine, avoid liquid medicine precipitation, improve the liquid absorption efficiency, and ensure the stability of the concentration of the sprayed or transported liquid medicine, thereby improving the treatment effect.

[0040] The circulation mechanism 5 includes a main gear 51, the main gear 51 is fixedly connected to the outer wall of the communicating column 44. A stepping motor 52 is fixedly connected to the inner wall of the spherical bin 2. The output shaft of the stepping motor 52 is fixedly connected to a semi-gear 53.

One end of the scroll spring 54 is fixedly connected to the shaft of the secondary gear 55, and the other end of the scroll spring 54 is fixedly connected to the inner wall of the spherical bin 2. The secondary gear 55 meshes with the main gear 51.

[0041] In summary, when using this dressing change stand for diabetic foot, turn on the electric fan 38 and the heating device 39. The heating device 39 is used to heat the air, and the electric fan 38 is responsible for outputting the heated air. The temperature sensor 310 is used to monitor the air temperature in real time and feedback it to the heating device 39, so that the heating device 39 adjusts the heating intensity according to the feedback of the temperature sensor 310 to ensure that the temperature of the output air always remains within the set safe range. The hot air output by the electric fan 38 can pass through the inner walls of the bottom support column 31, the top support column 32, and the U-shaped footrest 33, and then be discharged through the footrest exhaust port 311. This means that the hollow interior of the U-shaped footrest 33 will pass through hot air, heating the U-shaped footrest 33, which helps to warm the surrounding environment and directly improve the comfort of the user, especially when used in a cold environment. Through the dissipation of hot air, a warm experience can be provided.

[0042] The hot air in the top support column 32 will also enter the sandwich cavity 312 through the through-tube 36 and then be output and blown through the annular exhaust port 313, so as to form a positive pressure environment in the spherical chamber 2, thereby preventing pollutants in the external air from entering the spherical chamber 2, maintaining the cleanliness and sterility of the treatment area, and improving the safety of treatment or operation.

[0043] Then turn on the water pump 43. When the water pump 43 sucks liquid through the hollow annular part 410 and the inclined liquid inlet 411, a reverse acting force will be generated when the inclined liquid inlet 411 sucks liquid, driving the hollow annular part 410 to rotate, so that the inclined liquid inlet 411 rotates to absorb the liquid medicine. Rotary liquid absorption can make the surrounding liquid medicine flow more evenly, reduce precipitation, ensure the stability of the concentration of the absorbed liquid medicine. At the same time, the hollow annular part 410 drives the fan blade 412 to rotate, stirring the liquid medicine, which can further enhance the uniformity of the liquid medicine, avoid liquid medicine precipitation, improve the liquid absorption efficiency, and ensure the stability of the concentration of the sprayed or transported liquid medicine, thereby improving the treatment effect.

[0044] The liquid medicine output by the output end of the water pump 43 is output and sprayed through the connecting column 44, the arc-shaped connecting part 45, and the nozzle 46.

[0045] Then, start the stepper motor 52 to drive the half gear 53 to rotate. The half gear 53 drives the main gear 51 to rotate, the main gear 51 drives the secondary gear 55 to rotate, and the secondary gear 55 drives the scroll spring 54 to store energy. The main gear 51 drives the connecting column 44, the arc-shaped connecting member 45, and the nozzle 46 to rotate. After the arc-shaped connecting member 45 rotates to the other side of the top support column 32, the toothless part of the half gear 53 rotates to one side of the main gear 51, so that the half gear 53 no longer meshes with the main gear 51 at this time. At this time, the scroll spring 54 releases to drive the secondary gear 55 to rotate, and the secondary gear 55 drives the main gear 51 to reverse and return to its original position until the toothed part of the half gear 53 continues to mesh and drive the main gear 51 to rotate. This cycle repeats, causing the nozzle 46 to rotate back and forth in a reciprocating motion for spraying, enabling the liquid medicine to evenly cover the target area, improving the uniformity of spraying and the treatment effect, and at the same time avoiding the problem of uneven coverage caused by a fixed spraying angle, thereby enhancing the utilization rate of the liquid medicine and the treatment efficiency.
