Please refer to fig. 1 and 3, a water pump 38 is installed on the top of the liquid medicine box 3, an input end of the water pump 38 is connected to a liquid inlet pipe 39 penetrating the liquid medicine box 3, an output end of the water pump 38 is connected to a liquid outlet pipe 40, a heater 41 is disposed in the middle of the liquid outlet pipe 40, and a nozzle 42 is disposed at one end of the liquid outlet pipe 40.

This kind of medical orthopedics device of changing dressings can heat the liquid medicine through the heater 41 that sets up, avoids the liquid medicine that the temperature is low excessively to cause secondary injury to patient's affected limb.

Referring to fig. 6, 7 and 8, a latch 31 is disposed at one end of the first magnet block 24, and a latch slot 32 is disposed at one end of the second magnet block 25 and is matched with the latch 31.

This kind of supplementary device that changes dressings based on orthopedics is clinical can slide in the inside of draw-in groove 32 through the fixture block 31 that sets up, and second electromagnetism piece 25 can rotate better when being convenient for second electromagnetism piece 25 and first electromagnetism piece 24 outage.

Referring to fig. 10, a second piston rod 51 penetrating to the top of the second device case 49 is disposed inside the second device case 49, and a plurality of sets of weights 52 are disposed on the top of the outside of the second piston rod 51.

This kind of auxiliary device changes dressings based on orthopedics is clinical cup joints in the outside of second piston rod 51 through the weight 52 that sets up, and weight 52 can increase quantity at will, and then more convenient adjustment to second piston rod 51 weight of pushing down, and it is more convenient to use.

The working principle is as follows: when the medical liquid medicine box is used, medical staff puts liquid medicine into the liquid medicine box 3 in advance, then the spongy cushion 43, the film 44 and the bandage 45 are wrapped from inside to outside in sequence, because the arc-shaped sheet 53 is of an arc-shaped elastic structure, the spongy cushion 43, the film 44 and the bandage 45 wrapped outside the arc-shaped sheet 53 can be of the arc-shaped structure, then a nurse pulls the fixing rope 59 outwards, two ends of the bandage 45 are fastened by using the fixing rope 59, when the bandage 45 needs to be replaced, only the fixing rope 59 needs to be untied, meanwhile, the fixing rope 59 can be wound outside the winding roller 56 under the action of the second spring 57 when not used, the condition that the fixing rope is exposed outside for a long time to cause artificial damage is avoided, a patient can independently complete medicine changing after the bandage 45, the affected limb is firstly placed on the sliding plate 36, then the sliding plate 36 is pressed downwards by using the uninjured part, the arranged sliding plate 36 can drive the placing plate 10 and the sleeve 7 to move downwards, so that the sleeve 7 drives the fixing plate 11 and the first rack 13 to move downwards, the fixing plate 11 triggers the switch 12 after descending to a certain distance, at the moment, the water pump 38 is started, the water pump 38 pumps a certain amount of liquid medicine in the liquid medicine box 3 into the liquid outlet pipe 40, and then the liquid medicine is sprayed out through the spray head 42, because the liquid outlet pipe 40 is internally provided with the pressure reducing valve, the spray head 42 can only drip the liquid medicine and can not spray, so that the bandage 45 on the first roller 19 can fully absorb the liquid medicine, meanwhile, the first rack 13 is matched with the first gear 14, the first gear 14 is matched with the second gear 15, so that the second gear 15 drives the second rack 16 to move downwards, the second rack 16 drives the mounting frame 17 to move downwards, because the radius of the second gear 15 is half of the radius of the first gear 14, when the first gear 14 rotates for one circle, the second gear 15 can rotate for two circles, when the first rack 13 descends for a certain distance, the second rack 16 can descend for twice the same distance, so that the descending speed of the mounting rack 17 is always faster than that of the placing plate 10, the first roller 19 and the second roller 20 can contact the affected limb of the patient, meanwhile, the second gear 15 can drive the fourth gear 28 to rotate when rotating, under the action of the fourth rack 29, the fourth gear 28 drives the fifth gear 30 and the sixth gear 33 to rotate, the sixth gear 33 drives the third rack 27 to rotate, so that the third gear 26 drives the second roller 22 to rotate, the second roller 22 drives the second bevel gear 23 to rotate, the second bevel gear 23 is matched with the first bevel gear 21, so that the first bevel gear 21 can drive the first roller 18 to rotate, and further, the first roller 19 and the second roller 20 can rotate, when a patient feels that the pressing force between the first roller 19 and the second roller 20 and the affected limb of the patient is right, the patient stops pressing the placing plate 10, then slowly moves the sliding plate 36 leftwards, the pressing block 37 on the left side of the sliding plate 36 can be in contact with the pressure switch 47 on one side of the supporting plate 46, the pressure switch 47 can cut off the power between the first electromagnetic block 24 and the second electromagnetic block 25 after being triggered, meanwhile, the third rack 27 can drive the first piston rod 50 to compress downwards when moving downwards, so that the gas in the first device box 48 can be continuously compressed and the hydraulic oil in the first device box 48 can enter the second device box 49, at the moment, the hydraulic oil in the second device box 49 is continuously increased and drives the second piston rod 51 to move upwards, and when the power between the first electromagnetic block 24 and the second electromagnetic block 25 is cut off, the weight 52 outside the second piston rod 51 can fall down and drive the second piston rod 51 to move downwards, the first piston rod 50 moves upwards and drives the third rack 27 to move upwards, so that the fifth gear 30 drives the fourth gear 28 to rotate, the first electromagnetic block 24 is not rotated when the second electromagnetic block 25 rotates due to the power failure between the first electromagnetic block 24 and the second electromagnetic block 25, and further the placing plate 10 is not lifted, the lifting of the third rack 27 can drive the first roller 19 and the second roller 20 to rotate for a certain time in the opposite direction, so that the first roller 19 and the second roller 20 can roll and apply medicine conveniently, meanwhile, when the arm of a patient contacts the bandage 45, the arc-shaped sheet 53 is stressed inwards to be compressed, so that the bandage 45 outside the arc-shaped sheet 53 can wrap the wounded area on the surface of the affected limb of the patient, and further the medicine can be applied conveniently by the patient, the medicine applying effect is better, after the patient applies medicine by using the first roller 19, the second drum 20 may be used to wipe the affected limb after the application of the medicine.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
