Detailed implementation manners

[0030] The technical solution provided by the present invention will be further described below in conjunction with the accompanying drawings and according to the specific implementation manners.

[0031] As Figures 1 to 13 shown, a dressing - changing aid for breast and thyroid treatment includes a smearing mechanism 1. The smearing mechanism 1 includes a pair of medicine storage bins 102. The tops of the medicine storage bins 102 are fixedly connected by a soft connecting plate 101. A pressing rubber plate 109 is fixedly installed between the bottoms of the medicine storage bins 102. A plurality of decontamination cotton sheets 117 are fixedly installed at the bottom of the pressing rubber plate 109 through Velcro. The decontamination cotton sheets 117 are used to adsorb the stains on the body surface of the patient. A plurality of movable support plates 103 are hinged between the medicine storage bins 102 through a connecting rod 104. Cylindrical keys are fixedly installed at the tops of the left and right sides of the medicine storage bins 102. A pair of cylindrical keys are fixedly installed at the outer tops of the movable support plates 103. The connecting rod 104 is hinged to the cylindrical keys at the tops of the medicine storage bins 102 and the movable support plates 103. While maintaining the distance between the two medicine storage bins 102, the multi - section hinged movable support plates 103 enable the device to change its own curvature according to the curvature of the human body surface, facilitating the pressing rubber plate 109 to better fit on the human body surface to wipe the affected area, and facilitating subsequent medicine application.

[0032] As Figures 1 to 13As shown in the figure, a chute is provided at the top inside the movable support plate 103. A transmission rod 108 is horizontally rotatably installed inside the medicine storage bin 102. Gears are fixedly installed at both the front and rear ends of the transmission rod 108. A rubber transmission belt 110 is rotatably installed between the two transmission rods 108. Gear teeth are provided on the inner ring of the rubber transmission belt 110. The gear teeth on the inner ring of the rubber transmission belt 110 mesh with the gears at both ends of the transmission rod 108. The transmission rod 108 is in sliding fit with the chute inside the movable support plate 103. A pulley is fixedly installed on the transmission rod 108. A first driving motor 111 is fixedly installed inside the medicine storage bin 102. A pulley is fixedly installed on the first driving motor 111. The first driving motor 111 and the transmission rod 108 are connected by a belt. A pressing mechanism 2 is horizontally slidably installed in the chute inside the movable support plate 103. The pressing mechanism 2 is used to press the affected area to assist in discharging the fluid in the wound, facilitating the postoperative recovery of the patient. The pressing mechanism 2 includes a sliding support frame 201. A positioning block is fixedly installed on the inner ring of the rubber transmission belt 110. Positioning grooves are provided at both ends of the sliding support frame 201. The positioning block on the inner ring of the rubber transmission belt 110 is fixedly connected to the positioning grooves on both sides of the sliding support frame 201. By starting the first driving motor 111 to drive the transmission rod 108 to rotate, the rotation of the transmission rod 108 drives the rubber transmission belt 110 to roll in the chute inside the movable support plate 103. The positioning block on the rubber transmission belt 110 drives the pressing mechanism 2 to reciprocally slide in the chute of the movable support plate 103, move along the affected area in a fitting manner, and clean and drain the affected area.

[0033] As Figures 1 to 13 shown, a driving crank 203 is horizontally rotatably installed inside the sliding support frame 201. A plurality of massage rods 205 are longitudinally slidably installed at the bottom of the sliding support frame 201. The bottom of the massage rod 205 is in contact and cooperation with the top of the pressing rubber plate 109. The massage rod 205 and the driving crank 203 are hinged by a massage transmission rod 204. A gear is fixedly installed at one end of the driving crank 203. A second driving motor 202 is fixedly installed at one end of the sliding support frame 201. A gear is fixedly installed on the second driving motor 202. The gear on the second driving motor 202 meshes with the gear on the driving crank 203. By starting the second driving motor 202 to drive the driving crank 203 to rotate, when the driving crank 203 rotates, it drives the massage rod 205 to longitudinally reciprocally slide inside the sliding support frame 201 through the massage transmission rod 204, and massages the affected area through the massage rod 205 to squeeze the fluid in the affected area.

[0034] As Figures 1 to 13As shown in the figure, a liquid medicine soaking bin 107 is fixedly installed at the bottom of the medicine storage bin 102 for temporarily storing the liquid medicine for applying to the affected area. A winding rod 105 is horizontally rotatably installed inside the liquid medicine soaking bin 107. A medicine applying plate 118 is wound and installed in the middle part of the winding rod 105. A cotton strip is fixedly installed at the top of the medicine applying plate 118 for adsorbing the liquid medicine. A liquid storage tank is arranged inside the medicine storage bin 102. An inlet 106 is fixedly installed at the top of the medicine storage bin 102. The inlet 106 is communicated with the liquid storage tank inside the medicine storage bin 102. The liquid storage tank in the medicine storage bin 102 is communicated with the liquid medicine soaking bin 107 through a diversion pipe. An outlet chute is arranged at the top inside the liquid medicine soaking bin 107. The medicine applying plate 118 wound on the winding rod 105 extends out through the outlet chute on the liquid medicine soaking bin 107. Both ends of the sliding support frame 201 are fixedly installed with massage support rods 206 through telescopic rods. A pair of medicine applying support rods 207 are rotatably installed between the two massage support rods 206. The two medicine applying support rods 207 are respectively fixedly connected with one end of the medicine applying plates 118 wound on the two winding rods 105. Ratchets are arranged at both ends of the medicine applying support rod 207. Pawls are arranged inside the massage support rod 206. The ratchets at both ends of the medicine applying support rod 207 cooperate with the pawls inside the massage support rod 206 to control the medicine applying support rod 207 to rotate only in one direction. When the sliding support frame 201 slides between the movable support plates 103, the two medicine applying support rods 207 are driven by the massage support rods 206 to move on the affected area. At the same time, the medicine applying support rod 207 at the front end in the sliding direction is controlled by the ratchet to roll between the massage support rods 206, squeezing the liquid medicine in the cotton strip at the top of the medicine applying plate 118 onto the affected area, controlling the medicine applying support rod 207 at the rear end in the sliding direction to stop sliding, for wiping off the excess liquid medicine and at the same time spreading the liquid medicine evenly, facilitating the recovery of the patient.

[0035] As Figures 1 to 13 shown, special-shaped wheels are fixedly installed at both ends of the winding rod 105. The special-shaped wheels are round wheels with four arc-shaped grooves evenly arranged on the outer ring. A pair of chutes are arranged on the left and right sides inside the medicine storage bin 102. A second limiting rod 114 is longitudinally slidably installed in the chute of the medicine storage bin 102. A semi-circular key is arranged at the bottom of the second limiting rod 114. The semi-circular key at the bottom of the second limiting rod 114 is in contact and cooperation with the arc-shaped grooves on the special-shaped wheels at both ends of the winding rod 105 for intercepting the rotational movement of the winding rod 105 in the liquid medicine soaking bin 107, preventing the medicine applying plate 118 between the medicine applying support rod 207 and the winding rod 105 from contacting the skin at other positions of the patient due to being too loose, resulting in waste of medicine.

[0036] As Figures 1 to 13As shown in the figure, friction drive wheels 115 are fixedly installed on both the left and right sides of the drive rod 108. A plurality of drive semi-circular keys 116 are fixedly installed on the outer ring of the friction drive wheels 115. A friction drive ring 112 is horizontally rotatably installed on the outer ring of the friction drive wheels 115. A plurality of drive sliding keys 119 are radially slidably installed on the inner ring of the friction drive ring 112. The drive sliding keys 119 are in contact and cooperation with the drive semi-circular keys 116. A compression spring is fixedly installed between the bottom of the drive sliding keys 119 and the friction drive ring 112. A convex rod is fixedly installed on the friction drive ring 112. A first limiting rod 113 is hinged on the convex rod of the friction drive ring 112. An adjustment chute is provided at the top of the second limiting rod 114. An adjustment rod is fixedly installed at the bottom of the first limiting rod 113. The adjustment rod at the bottom of the first limiting rod 113 is slidably installed in the adjustment chute at the top of the second limiting rod 114. A semi-circular groove is provided at the top of the first limiting rod 113. The semi-circular groove at the top of the first limiting rod 113 is in contact and cooperation with the outer ring of the friction drive ring 112. When the first drive motor 111 drives the drive rod 108 to rotate, the friction drive ring 112 is driven to rotate synchronously through the contact and cooperation between the drive semi-circular keys 116 and the drive sliding keys 119, and the second limiting rod 114 is driven to slide in the chute inside the medicine storage bin 102 through the first limiting rod 113. The winding rod 105 at the front end of the sliding support frame 201 in the sliding direction is stopped from rotating through the contact and cooperation between the semi-circular key at the bottom of the second limiting rod 114 and the semi-circular groove on the special-shaped wheels at both ends of the winding rod 105, ensuring that the medicine application plate 118 is in a taut state and improving the utilization rate of the liquid medicine.

[0037] Working principle: When it is necessary to perform wound care on a patient who has undergone breast and thyroid surgery, first place the device directly above the wound. Through the interconnection between the multiple movable support plates 103, the device is closely attached to the patient's wound. Then start the first drive motor 111 to drive the drive rod 108 to rotate, driving the sliding support frame 201 to slide between the movable support plates 103. At the same time, start the second drive motor 202 to drive the drive crank 203 to rotate inside the sliding support frame 201, driving the massage rod 205 to reciprocate inside the sliding support frame 201 to press on the wound, assisting medical staff to drain the accumulated fluid in the wound. At the same time, through the contact between the medicine application support rod 207 and the skin, the medicine application support rod 207 at the front end of the sliding support frame 201 is driven to rotate between the massage support rods 206, squeezing the liquid medicine in the cotton strip on the top of the medicine application plate 118 onto the wound. At the same time, the medicine application support rod 207 at the rear end of the sliding support frame 201 is restricted by the ratchet, and the excess liquid medicine at the wound is wiped off through the medicine application support rod 207 at the rear end, and the liquid medicine is evenly applied.

[0038] At the same time, the second limiting rod 114 is driven to slide in the chute of the medicine storage bin 102 through the drive rod 108, restricting the rotation of the winding rod 105 at the front end of the sliding direction of the medicine storage bin 102, keeping the medicine application plate 118 taut, and preventing waste of the liquid medicine.
