DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0028] As Figures 1-7The burn wound drying device is characterized in that a sleeve joint mechanism 3 for controlling drying area adjustment is movably connected to the surface of the support 1, the sleeve joint mechanism 3 comprises two slide rings 31 slidably mounted on the surface of the support 1, a telescopic heat preservation layer 32 fixed between the slide rings 31, a rubber ring 33 fixed to the inner wall of the slide rings 31, a tooth roller 34 rotatably mounted around the slide rings 31, a cable 35 wound on the tooth roller 34, a tooth ring 36 rotatably sleeved around the slide rings 31, a telescopic rod 37 slidably connected to the right wall of the slide rings 31, a groove 38 fixed to the bottom of the telescopic rod 37, a pin rod 39 slidably inserted into the bottom of the slide rings 31 and abutting against the inner wall of the support 1, a heating mechanism 4 fixed to the rear end of the sleeve joint mechanism 3 for providing hot air, the heating mechanism 4 comprises an electromagnetic exhaust valve pipe 41 fixed to the inner wall of the slide rings 31, an inlet electric heating valve disc 42 fixed to the bottom of the slide rings 31, a special-shaped exhaust valve pipe 43 fixed to the inlet electric heating valve disc 42, a fan 44 rotatably mounted on the port of the special-shaped exhaust valve pipe 43, one end of the special-shaped exhaust valve pipe 43 along the direction of the fan 44 being in communication with the inner cavity of the telescopic heat preservation layer 32, an electric push rod 45 fixed to the bottom of the inlet electric heating valve disc 42, an electromagnetic disc 46 fixed to the front end of the electric push rod 45, a telescopic disc 47 fixed to the rear end of the electromagnetic disc 46, and a telescopic heat preservation sleeve 48 fixed between the telescopic disc 47 and the inlet electric heating valve disc 42.

[0029] More specifically, by controlling the electric push rod 45 to drive the electromagnetic disc 46 to expand the telescopic thermal sleeve 48 in an analogous manner according to the size of the wound area and the same telescopic volume of the telescopic thermal layer 32, the estimated demand air inhaled in the telescopic thermal sleeve 48 can be preheated by the inflow electric heating valve disc 42, and when the temperature detected by the temperature sensor on one side of the inflow electric heating valve disc 42 reaches the standard, the inflow electric heating valve disc 42 stops heating under feedback regulation. When positioning the arm later, the teeth ring 36 is deflected clockwise by pre-pressing the two telescopic rods 37 to lower, and each tooth roller 34 is wound around the cable 35 to expand the rubber ring 33, which facilitates the patient's arm to pass through the cuff 31 with the smallest covered area and supports and positions with the handrail 2. At the same time, the pin rod 39 moves left due to the downward movement of the slot 38 driven by the telescopic rod 37, which releases the movement restriction of the cuff 31, and the two cuffs 31 can be controlled to move to the edge of the wound, and then the sealing of the rubber ring 33 and the positioning of the cuff 31 are reset, which realizes the optimal control of the dry space and the maximum utilization of heat. The heated air in the telescopic thermal sleeve 48 is fully pressed into the telescopic thermal layer 32 through the special-shaped exhaust valve pipe 43 by controlling the electromagnetic disc 46 to run fully repel the telescopic disc 47, and the original cold air in the telescopic thermal layer 32 is continuously discharged through the electromagnetic exhaust valve pipe 41. Since the wound is gradually heated, the temperature change of the wound is relatively gentle, the dry comfort of the wound is enhanced, and when the temperature change of the air discharged by the electromagnetic exhaust valve pipe 41 tends to be flat, the temperature sensor on the electromagnetic exhaust valve pipe 41 monitors and timely feedback controls to close the electromagnetic exhaust valve pipe 41. The synchronous fan 44 runs to make the hot air in the telescopic thermal layer 32 continuously flow in a closed manner to speed up the drying efficiency of the wound and reduce the waste of heat.

[0030] As shown in Figures 2-3 , in some embodiments, the middle edge of the rubber ring 33 includes an extension part expanding in the front-back direction, and the middle edge of the rubber ring 33 is fixedly connected with the cable 35, and the tooth roller 34 is engagedly connected with the teeth ring 36. When positioning the arm, the rubber ring 33 can be expanded by controlling the teeth ring 36 to drive each tooth roller 34 to wind the cable 35, so that the patient's arm can pass through the cuff 31 conveniently, and when the rubber ring 33 restores, the extension part of the middle edge of the rubber ring 33 plays a sealing role to avoid the subsequent heat loss in the telescopic thermal layer 32.

[0031] As shown in Figure 2 and Figure 7 , in some embodiments, the telescopic rod 37 is rotationally connected to the right wall of the teeth ring 36, and the telescopic rod 37 is controlled to move up and down to control the deflection of the teeth ring 36, thereby conveniently controlling the opening and closing state of the rubber ring 33.

[0032] As shown in Figure 4As shown, in some embodiments, the bottom of the groove 38 is provided with a curved groove that engages with the pin 39. The curved groove includes an inclined portion at the top and a vertical portion at the bottom. Initially, the pin 39 abuts against the inner wall of the bearing 1 to limit the position of the retaining ring 31. When the groove 38 is controlled to move downward, the pin 39 is guided to move to the left to release the positioning restriction on the retaining ring 31.

[0033] like Figures 5-7 As shown, in some embodiments, the two ends of the electromagnetic drain valve pipe 41 are connected to the inner cavity of the telescopic insulation layer 32 and the outside, respectively. Temperature sensors are fixed at the end of the electromagnetic drain valve pipe 41 connected to the outside and at the side where the inlet electric heating valve disc 42 is connected to the telescopic insulation sleeve 48. The temperature sensors respectively provide feedback control to the inlet electric heating valve disc 42, the electromagnetic drain valve pipe 41 and the fan 44. When the temperature sensor on the side of the inlet electric heating valve disc 42 detects that the temperature of the preheated air drawn into the telescopic insulation sleeve 48 meets the standard, the inlet electric heating valve disc 42 is adjusted by feedback and stops heating to avoid overheating. When the temperature sensor on the electromagnetic drain valve pipe 41 detects that the temperature change of the air discharged from the electromagnetic drain valve pipe 41 tends to be gradual, the electromagnetic drain valve pipe 41 is controlled by feedback and closes in time. The fan 44 runs synchronously, so that the hot air inside the telescopic insulation layer 32 continuously circulates in a closed manner to accelerate the drying efficiency of the wound and reduce the waste of heat.

[0034] like Figure 1 and Figure 5 As shown, in some embodiments, both the electric disk 46 and the telescopic disk 47 are slidably connected to the inner wall of the support 1. When the electric disk 46 is energized, the magnetic poles on the side adjacent to the telescopic disk 47 are the same. The elastic force of the telescopic disk 47 is much greater than the elastic force of the telescopic insulation sleeve 48. When the electric push rod 45 is extended to control the movement of the electric disk 46, the inner wall of the support 1 provides support for the electric disk 46 and the telescopic disk 47, and the telescopic insulation sleeve 48 is stably stretched and expanded to draw in air. Subsequently, when the electric disk 46 is energized, the telescopic disk 47 is then subjected to corresponding pressure deformation to expel the air in the telescopic insulation sleeve 48.

[0035] like Figures 5-6 As shown, in some embodiments, the telescopic insulation sleeve 48 and the telescopic insulation layer 32 have the same volume under the same extension length. The telescopic insulation sleeve 48 is connected to the irregularly shaped drain valve pipe 43. Based on the size of the wound area and the fact that the telescopic insulation sleeve 48 and the telescopic insulation layer 32 have the same extension volume, the electric push rod 45 is controlled in an analogous manner to drive the electric disk 46 to expand the telescopic insulation sleeve 48. The estimated required air drawn into the telescopic insulation sleeve 48 can be preheated by the inlet electric heating valve plate 42. Then, the preheated air can be input into the telescopic insulation layer 32 by the irregularly shaped drain valve pipe 43 to satisfy the venting of sufficient cold air from the telescopic insulation layer 32.

[0036] like Figures 1-4As shown, in some embodiments, the sleeving mechanism 3 includes two slidingly mounted on the surface of the seat 1 ring 31, fixed between the ring 31 stretch insulation layer 32, fixed in the inner wall of the ring 31 rubber ring 33, rotatingly mounted around the ring 31 toothed roller 34, on the toothed roller 34 winding cable 35, rotatingly sleeved on the outer periphery of the ring 31 toothed ring 36, slidingly connected to the right wall of the ring 31 telescopic rod 37, the bottom of the telescopic rod 37 is fixed with a groove 38, the bottom of the ring 31 is slidingly connected with the pin 39 abutting the inner wall of the seat 1, specifically, the two main bodies of the sleeving mechanism 3 can be adjusted along the seat 1, when positioning the arm, the two telescopic rods 37 are pressed downward to make the ring 31 close, and the middle part of the rubber ring 33 is expanded, that is, the patient's arm is conveniently put through the ring 31 to cooperate with the handrail 2 for supporting and positioning, and then the two rings 31 are adjusted step by step to be respectively on both sides of the wound area, and the rubber ring 33 is reset and sealed, that is, the optimization control of the dry space and the maximum utilization of heat are realized.

[0037] As shown, Figures 5-7 As shown, in some embodiments, the heating mechanism 4 includes an electromagnetic exhaust valve pipe 41 fixed in the inner wall of the ring 31, an inlet electric heating valve disc 42 fixed at the bottom of the ring 31, a special-shaped exhaust valve pipe 43 fixed on the inlet electric heating valve disc 42, a fan 44 rotatingly mounted on the port of the special-shaped exhaust valve pipe 43, one end of the special-shaped exhaust valve pipe 43 along the direction of the fan 44 is in communication with the inner cavity of the stretch insulation layer 32, the bottom of the inlet electric heating valve disc 42 is fixed with an electric push rod 45, the front end of the electric push rod 45 is fixed with an electromagnetic disc 46, the rear end of the electromagnetic disc 46 is fixed with a telescopic disc 47, and the telescopic disc 47 is fixed between the inlet electric heating valve disc 42 and the stretch insulation sleeve 48, specifically, according to the size of the wound area and the same telescopic volume of the stretch insulation sleeve 48 and the stretch insulation layer 32, the electric push rod 45 drives the electromagnetic disc 46 to expand the stretch insulation sleeve 48 in an analogous manner, that is, the estimated required air in the stretch insulation sleeve 48 is preheated by the inlet electric heating valve disc 42, when the temperature detected by the temperature sensor meets the standard, the inlet electric heating valve disc 42 stops heating, the electromagnetic disc 46 runs to repel the telescopic disc 47, so that the heated air in the stretch insulation sleeve 48 is fully pressurized to the stretch insulation layer 32 through the special-shaped exhaust valve pipe 43, during which the original cold air in the stretch insulation layer 32 is continuously discharged by the electromagnetic exhaust valve pipe 41, which makes the temperature change of the wound area more gentle, when the temperature change of the air discharged by the electromagnetic exhaust valve pipe 41 tends to be flat, the corresponding temperature sensor monitors and feeds back to control the electromagnetic exhaust valve pipe 41 to close, and the fan 44 runs synchronously, so that the hot air in the stretch insulation layer 32 continuously flows in a closed manner, to speed up the drying efficiency of the wound area and reduce the waste of heat.
