In view of the situation where serious illness is referred to a large hospital and later rehabilitation treatment is returned to a community hospital, if the community hospital can make full use of the medical imaging data obtained in the large hospital, it will help the doctors in the small hospital to better understand the condition and reduce the inspection time. Improve diagnosis and treatment efficiency. However, because most of the medical inspection systems in various hospitals are still closed, doctors in community hospitals mainly use the printed medical image light films to understand the previous inspection results.

Existing medical imaging light films such as X-ray films are basically placed directly in the corresponding handbags. In actual use, medical imaging light films are usually taken directly by hand, and are often temporarily placed outside after viewing. There are many opportunities for contamination. Before the patient goes to the community hospital, these medical image light films are brought back by the patient or their family members, which are more prone to scratches or stains. Similar to the way that some photo surfaces are protected by being sandwiched by a protective film, the medical imaging light film can also be placed in a transparent protective film interlayer for protection, so that the medical imaging light film itself is not easily affected due to the protection of the protective film when placed or viewed.

When the 8 is output upward, the upper conveying wheel 31 is actively rotated to sandwich the medical image light sheet 8 between the protective films 7 and output upward.

Before the present invention is used, a certain amount of clean water or cleaning liquid is firstly loaded into the cleaning water tank 52, and the power is turned on to prepare for use. When viewing the medical image light sheet 8 covered with the protective film 7 , in order to prevent the stains on the protective film 7 from affecting the viewing effect, the user puts it from the upper part of the device, that is, from the upper conveying wheel 31 Put in, pay attention to let the concave-convex side edges 72 contact the upper conveying wheels 31 on the left and right sides respectively. Then, the upper conveying wheel 31 is activated to send the medical image light sheet 8 downward.

When the medical image light sheet 8 passes through the photoelectric sensor, the photoelectric sensor temporarily stops the upper conveying wheel 31, and the opening edge 73 of the protective film 7 is between the heaters 43 and the heater 43 is turned on to heat it. Since the outer side of the opening edge 73 is fixedly attached with a shrinking strip 74 , the shrinking strip 74 is made of a reversible thermally shrinkable material, such as a polyaramide material; In this way, when the opening edge 73 is heated, the opening edge 73 expands outward because the shrinking strip 74 shrinks or the expansion volume of the shrinking strip 74 is smaller than that of the inner protective film 7 .

After heating for a short period of time to make the opening edge 73 open outward, the controller automatically starts the driving device to make the driving shaft 45 in the take-up roller 41 rotate, first from the bottom to the inside, and the original part of the roller 41 is located in the take-up roller 41. The elastic retractable strip 42 protrudes outward, and the extension end 422 with the clip is extended along the guide rail 44 from the outlet of the clip. Due to the blocking by the side wall protruding plate 425, the elastic opening and closing sleeve 423 is blocked here, and the elastic retractable strip 42 Continue to extend a part, push the V-shaped clip 421 out of the elastic opening and closing sleeve 423 so that the V-shaped clip 421 is naturally opened outward, and the opened opening edge 73 enters the opened V-shaped clip 421 .

First start the lower conveying wheel 32 to convey the clamped medical image light sheet 8 upward, and convey it upward through the adjacent guide groove body 33 until the upper end of the medical image light sheet 8 contacts the bottom edge of the upper sealing edge 71, The transport wheel 31 rotates synchronously with it to transport the medical image light sheet 8 upward. At this time, the driving shaft 45 and the upper conveying wheel 31 are in a state of co-rotating. The upper conveying wheel 31 presses the concave-convex side edges 72 of the protective film 7 with each other and conveys them upwards, and at the same time, the protective film 7 and the protective film 7 on the take-up roller 41 are also conveyed upward. The clip is pulled outwards, and the protective film 7 is pressed by the upper conveying wheel 31 to wrap the medical imaging light sheet 8 again.

When the protective film 7 passes the heating lamp 56 , the heating lamp 56 bakes the surface of the protective film 7 to dry it in the on state, but when the opening edge 73 approaches the heating lamp 56 , the heating lamp 56 is automatically turned off to prevent the shrinking strip 74 from being heated. The clip and the elastic stretchable strip 42 are pulled out, and finally the clip is pulled between the heaters 43. At this time, because the elastic opening and closing sleeve 423 is blocked by the baffle plate 426 again, the V-shaped frame is pushed out again, and the protection is released. The opening edge 73 of the film 7, because the shrink strip 74 that has been cleaned and has not been heated at this time will not shrink, so as to prevent the opening edge 73 from opening outward, so when the concave-convex side edges 72 are pressed together, the opening edge 73 naturally Adducted, the bottom is attached to prevent the medical imaging light sheet 8 from falling out from the bottom. Finally, the upper conveying wheel 31 outputs the recovered medical imaging light sheet 8 covered with the protective film 7 from the top, and finally the clip is recovered into the cleaning box 51 by the driving shaft 45 along with the elastic retractable strip 42 .
