The output shaft of the motor 132 and the right rotating shaft 9 are driven by a synchronous belt assembly.

[0036] See also Figure 7As shown, the spray assembly includes an arc frame 14, a liquid adding pipe 141 and a water pump 142. The arc frame 14 is symmetrically fixed to the upper inner part of the left and right circular shells 3. The arc frame 14 can be used to place disinfectant and water. The top middle of the arc frame 14 is connected with a liquid adding pipe 141. The liquid adding pipe 141 passes through the top of the circular shell 3. A water pump 142 is installed at the bottom of the arc frame 14. The water outlet end of the water pump 142 faces the electric wiping frame 121, and the water pump 142 is electrically connected to the control panel 21.

[0037] First, pour an appropriate amount of hydrogen peroxide into the liquid filling cylinder 7. The hydrogen peroxide is medical grade hydrogen peroxide with a concentration of 3%. Discharge an appropriate amount of disinfectant into one of the arc-shaped frames 14 through the liquid filling tube 141. Then discharge an appropriate amount of clean water into the other arc-shaped frame 14 through the liquid filling tube 141. Then cover the shell 1 on the patient's chest and cardiovascular surgery wound, and make the fitting pad 12 contact with the patient's skin. Then pull the elastic bandage 2 to fix the shell 1 through the effect of Velcro. Press the control panel 21 to control the atomizing nozzle 8 to start through the control module. The atomizing nozzle 8 starts to atomize and spray the hydrogen peroxide in the liquid filling cylinder 7. The atomized hydrogen peroxide contacts the disinfection cotton pad 4, and the hydrogen peroxide penetrates into the disinfection cotton pad 4. Then press the control panel 21 to control the control panel 21 to start the atomizing nozzle 8. The micro fan 5 is reversed, and the micro fan 5 is reversed to discharge air into the shell 1 through the breathable net 6, and the air is blown onto the sterilized cotton pad 4, which sterilizes the air to prevent infection at the patient's chest wound. It is suitable for wound care after thoracic surgery. The sterilized air passes through the air guide holes of the sterilized cotton pad 4 and penetrates into the surface of the filter gauze 11. The air is then blown onto the patient's wound by the filter gauze 11. At the same time, the air is discharged from the contact position between the fitting pad 12 and the patient's chest skin through the groove on the fitting pad 12. This is repeated, so that the air can flow continuously to ventilate the wound position, which can not only protect the wound through the action of the protective plate 10 and the fitting pad 12, but also ensure the breathability of the wound position. , and the air can reduce the bacteria in the air after being filtered by the filter gauze 11 to prevent bacteria from infecting the wound. When the patient's wound is ventilated for a suitable time, first press the control panel 21 to control the atomizing nozzle 8 and the micro fan 5 to be closed through the control module, the air stops flowing and the hydrogen peroxide stops spraying, pull the elastic band 2 to loosen the shell 1, remove the shell 1 from the patient's chest surgery wound position, and the fitting pad 12 is out of contact with the patient's chest position. Press the control panel 21 again and control the motor 132 to rotate forward through the control panel 21. The motor 132 rotates forward and drives the worm 131 to rotate forward through the synchronous belt assembly. The worm 131 rotates forward and drives the worm gear 13 to reverse. The worm gear 13 reverses and drives the left and right shafts 9 to reverse. The shaft 9 reverses and drives The protection plate 10 is reversed, and the protection plate 10 reverses to drive the fitting pad 12 and the filter gauze 11 to reverse, and the right protection plate 10 is reversed to the right electric wiping frame 121. At this time, the right protection plate 10 drives the right fitting pad 12 to reverse and contact with the electric wiping frame 121. At the same time, the left protection plate 10 is reversed to contact with the bottom of the shell 1. At this time, the left fitting pad 12 is reversed to the bottom of the shell 1 for use, and the motor 132 is turned off. The worm 131 stops driving the worm gear 13 to reverse, and the protection plate 10 stops driving the fitting pad 12 to reverse. It can be used again according to the above operation, and at the same time, the control panel 21 is pressed to control the water pump 142 corresponding to the clean water on the right to start through the control module. The water pump 142 corresponding to the clean water on the right pumps the clean water in the arc frame 14 out.The extracted clean water is sprayed onto the electric wiping frame 121 by the water pump 142, and the electric wiping frame 121 is started again to rotate to clean and remove impurities from the used bonding pad 12 with clean water. When the bonding pad 12 is cleaned and the impurities are removed, the water pump 142 corresponding to the clean water on the right is turned off, and the water pump 142 corresponding to the disinfectant on the right is started again. The water pump 142 corresponding to the disinfectant on the right draws out the disinfectant in the arc frame 14, and the extracted disinfectant is sprayed onto the electric wiping frame 121 by the water pump 142, and the electric wiping frame 121 is started again to rotate to disinfect the used bonding pad 12 with disinfectant. In this way, the wound can continue to be protected while being disinfected, so that it can be used continuously, thereby improving the use efficiency. When the disinfection of the bonding pad 12 is completed, the electric wiping frame 121 and the water pump 142 are turned off, and the disinfectant stops spraying. Similarly, when it is necessary to remove it again, the motor 132 is started to drive the worm 131 to rotate forward, so that the protective plate 10 rotates forward and drives the bonding pad 12 to rotate forward. The left bonding pad 12 rotates forward into the left circular shell 3, and the sterilized bonding pad 12 on the right rotates forward to the use position, and the device can be used again. When the filter gauze 11 has been used for a long time and has reached the end of its service life, the filter gauze 11 can be removed from the protective plate 10 for replacement, and a new filter gauze 11 can be installed on the protective plate 10.

[0038] See also Figure 9 As shown, the wound protection device for thoracic and cardiovascular surgery also includes a wiping assembly installed between the round shell 3 and the electric wiping frame 121.

The fixed disk 154 is fixedly connected to the middle part of the inner side of the circular shell 3 along the circumferential direction. The contact ball 155 is rotatably connected to the eccentric position of the bottom of the fixed disk 154. The contact ball 155 contacts the top of the drive ring 152. When the drive ring 152 rotates, the contact ball 155 can drive the drive ring 152 to move downward.

[0039] See also Figure 10-12As shown, the wound protection device for thoracic and cardiovascular surgery also includes a cleaning component installed between the shell 1 and the micro fan 5, the cleaning component includes an annular plate 16, a discharge pipe 161, an opening and closing component and a brush plate 166, the outer top of the shell 1 is fixedly connected to the annular plate 16, the middle part of the front side of the annular plate 16 is connected to the discharge pipe 161, the shaft of the micro fan 5 is connected to the brush plate 166 through a one-way clutch, the brush plate 166 is in contact with the air permeable net 6, when the brush plate 166 rotates, the brush plate 166 can remove impurities attached to the air permeable net 6, and a brush plate 166 is provided between the annular plate 16 and the micro fan 5. The opening and closing component can realize the opening and closing and closing of the annular plate 16; the opening and closing component includes a four-hole disk 162, a cross plate 163 and a rotating rod 164. The upper inner part of the annular plate 16 is connected to the four-hole disk 162 in a circumferential direction. The four-hole disk 162 is circumferentially provided with a guide groove 1621. The middle part of the annular plate 16 is rotatably connected with the rotating rod 164. The rotating rod 164 is fixedly connected to the top end of the shaft of the micro fan 5. The upper part of the rotating rod 164 is fixedly fitted with a cross plate 163. The cross plate 163 is located in the guide groove 1621. The cross plate 163 can realize the opening and closing and closing of the holes of the four-hole disk 162.

[0040] When the protective plate 10 drives the bonding pad 12 to rotate and contact with the electric wiping frame 121, the protective plate 10 also drives the filter gauze 11 to rotate and contact with the brush plate 151, and then the electric wiping frame 121 rotates to first clean the used bonding pad 12 with water to remove impurities, and part of the clean water will be discharged through the liquid guide hole 156 and contact with the brush plate 151. At the same time, the electric wiping frame 121 drives the guide rod 15 to rotate circumferentially, and the circumferential rotation of the guide rod 15 drives the driving ring 152 and the brush plate 151 to rotate. The brush plate 151 rotates to first wipe and clean the filter gauze 11 with clean water to remove the hydrogen peroxide and impurities on the filter gauze 11. When the filter gauze 11 is clean, the clean water stops being discharged, and the electric wiping frame 121 rotates to disinfect the used bonding pad 12 with disinfectant, and part of the disinfectant will pass through the liquid guide hole 156 is discharged and contacts with the brush plate 151, and the brush plate 151 rotates to wipe and disinfect the filter gauze 11 with the disinfectant. At the same time, the driving ring 152 rotates so that the convex part contacts the contact ball 155, and the contact ball 155 drives the driving ring 152 to move downward, and the connecting spring 153 is compressed. The driving ring 152 moves downward to drive the guide rod 15 to move downward, and the guide rod 15 drives the brush plate 151 to move downward. The driving ring 152 continues to rotate so that the convex part is out of contact with the contact ball 155. Due to the action of the connecting spring 153, the driving ring 152 moves upward and resets, and drives the brush plate 151 to move upward and reset through the guide rod 15, and so on. Whenever the brush plate 151 rotates, the brush plate 151 can continuously move up and down to slap the filter gauze 11, so that the disinfectant can better penetrate the filter gauze 11 for disinfection. When the electric wiping frame 121 is closed, the electric wiping frame 121 stops driving the guide rod 15 to rotate in a circle, and the guide rod 15 stops driving the driving ring 152 and the brush plate 151 to rotate, and the brush plate 151 also stops moving up and down. In this way, a large amount of bacteria on the filter gauze 11 can be prevented from affecting the subsequent filtering effect of the air, thereby improving the filtering effect of the filter gauze 11.

[0041] When the micro fan 5 is reversed, the micro fan 5 reverses and drives the rotating rod 164 to reverse, and the rotating rod 164 reverses and drives the cross plate 163 to reverse, and the cross plate 163 reverses and slides in the guide groove 1621, and the cross plate 163 stops reversing to close the holes of the four-hole disk 162, and the outside air can also be discharged into the annular plate 16 through the four-hole disk 162 through the air-permeable net 6. When the cross plate 163 reverses to the maximum stroke in the guide groove 1621, the cross plate 163 continues to reverse and drives the four-hole disk 162 to reverse through the guide groove 1621. Due to the effect of the one-way clutch, the reversal of the micro fan 5 will not drive the brush plate 166 to reverse, so as to prevent the brush plate 166 from reversing and removing impurities on the air-permeable net 6 from being sucked into the housing 1. When the micro fan 5 is turned off, the micro fan 5 stops driving The rotating rod 164 rotates in reverse, stops, and drives the cross plate 163 in reverse, starting the micro fan 5 to rotate forward, driving the rotating rod 164 in forward rotation. The forward rotation of the rotating rod 164 drives the cross plate 163 in forward rotation. The cross plate 163 rotates forward first, sealing the holes of the four-hole disk 162. The cross plate 163 then continues to rotate forward, driving the four-hole disk 162 in forward rotation. The micro fan 5 rotates forward, blowing air upward. Since the four-hole disk 162 is sealed, air flows and is discharged through the discharge pipe 161. At the same time, the forward rotation of the micro fan 5 drives the brush plate 166 in reverse via the one-way clutch. The reverse rotation of the brush plate 166 removes impurities attached to the air permeable mesh 6. The removed impurities are discharged through the discharge pipe 161 along with the air. When the impurities on the air permeable mesh 6 are completely removed, the micro motor is turned off and the brush plate 166 stops rotating. This prevents a large amount of impurities attached to the air permeable mesh 6 from affecting subsequent air flow, thereby ensuring the normal use of the air permeable mesh 6.

[0042] See also Figure 13 As shown, the wound protection device for thoracic and cardiovascular surgery also includes an adhesive cloth 17. Four adhesive cloths 17 are fixed to the outer side surface of the shell 1 at even intervals along the circumferential direction. The adhesive cloths 17 can stick the rolled elastic bandage 2.

[0043] When the device is not needed for wound protection, the four elastic bands 2 are rolled up, and then the Velcro on the elastic bands 2 is adhered to the adhesive cloth 17. The adhesive cloth 17 limits the position of the rolled elastic bands 2. When it is needed, the Velcro on the elastic bands 2 is pulled out of contact with the adhesive cloth 17, and the rolled elastic bands 2 are loosened for use. This prevents the elastic bands 2 from being stored in a loose state and causing knots to affect subsequent use, thereby facilitating subsequent use of the elastic bands 2.

[0044] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in this field based on the above content of the present invention are all within the scope of protection required by the present invention.
