[0058] Figure 1 This is a schematic structural diagram of a switching display panel according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 17This utility model provides an intravenous drug infusion dose conversion display panel 10, including a support 100, a rotating shaft 300, a dose disk 400, and a shielding cover 500. A suction cup 200 is provided on the rear side of the support 100. The rotating shaft 300 is horizontally positioned at the center of the support 100. The dose disk 400 has multiple dose areas 410 evenly distributed, each dose area 410 having a table 420, and each table 420 having a first dividing strip 430 at the line position. The dose disk 400 is rotatably mounted on the rotating shaft 300. Multiple handheld posts 440 are provided at the edge of the dose disk 400, each handheld post 440 being located at the connection point of two dose areas 410. The shielding cover 500 is fixedly disposed at the front end of the rotating shaft 300, and the front end of each handheld post 440 is rotatably mounted inside the shielding cover 500. The lower half of the shielding cover 500 has a viewing window corresponding to one dose area 410.

[0059] The support 100 is fixed by the suction cup 200. Multiple dosage zones 410 can correspond to multiple different intravenous drug dosage charts. Each dosage zone 410 is equipped with a table 420, on which the corresponding injection dosage of the intravenous drug can be filled in according to age or weight. The viewing window of the cover 500 is located at the bottom for easy viewing by medical personnel. Only one dosage zone 410 is visible, which can prevent medical personnel from misreading the dosage when comparing a certain intravenous drug dosage, thereby reducing the possibility of medical accidents. When it is necessary to switch to a different intravenous drug dosage chart, the handheld column 440 can be held and the dosage disc 400 can be rotated to make the dosage chart of the required intravenous drug visible through the viewing window.

[0060] Furthermore, in some embodiments of this utility model, such as Figure 5As shown, the number of dose regions 410 is even. The shielding cover 500 includes a support ring, multiple support strips, multiple fixed covers 530, and multiple movable covers 540. The support ring is coaxially arranged with the rotating shaft 300, and has a rearward-facing sliding groove. The front end of the handheld column 440 is provided with a ball head, which is inserted into the sliding groove. One end of each support strip is connected to the rotating shaft 300, and the other end is connected to the support ring. The size of the area between two adjacent support strips corresponds to the size of one dose region 410. The size of each fixed cover 530 corresponds to the size of one dose region 410. Each fixed cover 530 is fixedly disposed between two corresponding support strips. A fluoroscopic window is formed between every two adjacent fixed covers 530. The size of each movable cover 540 corresponds to the size of one dose region 410. Each movable cover 540 is configured to open or close one fluoroscopic window. The fixed covers 530 have multiple fluoroscopic windows, and medical personnel can open one or more fluoroscopic windows according to their own habits. When medical staff need to simultaneously view the corresponding injection dosage of one or more intravenous drugs with age or weight, they can use one or more movable covers 540 to open the corresponding fluoroscopic window.

[0061] Furthermore, in some embodiments of this utility model, such as Figures 5 to 6 As shown, each movable cover 540 is mounted on a fixed cover 530 and is rotatably mounted about a pivot 300. Each fixed cover 530 has a first positioning post 550, and the corresponding movable cover 540 has two first positioning grooves 560. When the first positioning post 550 is inserted into one of the first positioning grooves 560, the corresponding movable cover 540 and the fixed cover 530 overlap. When the first positioning post 550 is inserted into the other first positioning groove 560, the corresponding movable cover 540 blocks the corresponding viewing window. When it is necessary to open a viewing window, the movable cover 540 is rotated, and the first positioning post 550 is inserted into one of the first positioning grooves 560, at which point the viewing window is opened. When it is necessary to close a viewing window, the movable cover 540 is rotated again, and the first positioning post 550 is inserted into the other first positioning groove 560, at which point the viewing window is closed.

[0062] In some embodiments of this utility model, such as Figure 7 As shown, the movable cover is provided with a handle 580. When it is necessary to rotate the movable cover, the handle 580 can be held. Since the movable cover is relatively thin, it will deform under force, the first positioning pin will disengage from the first positioning groove, and the movable cover will be moved.

[0063] In some embodiments of this utility model, such as Figure 7 and 8As shown, the movable cover includes a mounting plate portion 542, a shielding plate portion 541, and a connecting plate portion 543 connecting the mounting plate portion 542 and the shielding plate portion 541. The mounting plate portion has a mounting hole into which a rotating shaft is inserted. The shielding plate portion is located outside and behind the mounting plate portion, and is used to shield the viewing window. The connecting plate portion 543 connects the end of the mounting plate portion 542 away from the mounting hole and the end of the shielding plate portion 541 near the mounting hole. The widths of the connecting plates of the multiple movable covers are different along the front-to-back direction, so that the multiple shielding plates are in the same plane.

[0064] In some embodiments of this utility model, such as Figure 10 and 11 As shown, the conversion display panel 10 also includes a rotating disk 600, a second positioning post 110, a first elastic element 140, and a plurality of second positioning grooves. The rotating disk 600 is disposed on the rear side of the dosage disk 400. The rotating disk 600 is rotatably mounted on the rotating shaft 300, and the dosage disk 400 is connected to the rotating disk 600. A rotating post 630 is disposed on the rotating disk 600, and the rotating post 630 has a through hole for insertion into the rotating shaft 300. The dosage disk 400 is connected to the rotating post 630. The second positioning post 110 is telescopically disposed on the support 100 in the front-rear direction. The first elastic element 140 is disposed between the second positioning post 110 and the support 100 to cause the second positioning post 110 to move forward. A plurality of second positioning grooves are disposed on the rear side of the rotating disk 600 so that after the dosage disk 400 rotates to switch a dosage area 410, the second positioning post 110 is inserted into a second positioning groove. When it is necessary to switch the display content, the hand-held column, the dosage disk and the rotating disk 600 rotate simultaneously. When the dosage disk and the rotating disk 600 rotate to the point where the second positioning post 110 set on the support 100 corresponds to a second positioning groove, the second positioning post 110 moves forward under the drive of the first elastic member 140 and inserts into a second positioning groove. The dosage disk stops rotating, thus realizing the switching of the display content.

[0065] Furthermore, in some embodiments of this utility model, such as Figure 16 As shown, the top of the second positioning post 110 is spherical, and the depth of the middle part of the second positioning groove 610 is greater than the depth of both ends. When it is necessary to rotate again, hold the hand post 440 by hand and rotate the dosing plate and the rotating plate 600, and the top of the second positioning post 110 will rotate out of the second positioning groove 610.

[0066] In some embodiments of this utility model, such as Figure 14 and Figure 15 As shown, the conversion display panel 10 also includes multiple expansion panels, each of which is retractable and extendable behind a dosage area 410. The expansion panels can record non-standard doses of intravenous drug infusions, such as the dose for overweight patients; these are not normally opened but are opened when needed.

[0067] Furthermore, in some embodiments of this utility model, such as Figure 14 and Figure 15 As shown, each expansion disc includes a main disc 710, a second elastic member 740, and two sub-discs 720. The main disc 710 is movably disposed on the rear side of the dosing disc 400 along the radial direction of the dosing disc 400. The second elastic member 740 connects the main disc 710 and the rotating post 630 and is configured to cause the main disc 710 to move inward. The two sub-discs 720 are disposed on both sides of the main disc 710 and are expandable relative to the main disc 710. Each sub-disc 720 has a first edge strip 730 on its edge, which extends along the radial direction of the dosing disc 400 and is movably disposed along the boundary of the corresponding dosing region 410 and along the radial direction of the dosing disc 400. When the expansion disk is needed, pull the main disk 710, causing the first edge strip 730 of each sub-disk 720 to move outward along the boundary of the corresponding dose area 410 and in the radial direction of the dose disk 400. This causes the main disk 710 to move outward in the radial direction of the dose disk 400. Once in position, the two sub-disks 720 naturally open. The arrangement of the sub-disks 720 can expand the display area of ​​the expansion disk.

[0068] In some embodiments of this utility model, such as Figure 17As shown, a third positioning groove 740 is provided on the rear side of the main disk 710. The third positioning groove 740 is a strip-shaped groove with an arc shape. The depth of the middle part of the strip-shaped groove is greater than the depth of the two ends, and the bottom surface of the strip-shaped groove includes two symmetrically arranged half-bottom surfaces, which are located on both sides of the middle part of the strip-shaped groove. A strip-shaped hole 620 is provided at a corresponding position on the rotating disk 600. The two ends of the strip-shaped hole 620 are inclined surfaces, and each half-bottom surface is connected to the corresponding inclined surface and is on the same plane. Multiple third positioning posts 120 are telescopically provided on the support 100. A third elastic element 130 is fitted on each third positioning post 120 to cause the third positioning post 120 to extend forward, pass through the corresponding strip-shaped hole 620, and insert into the third positioning groove 740. After the third positioning post 120 is inserted into the corresponding third positioning groove 740, the corresponding expansion disk is in an outwardly extended state. Once the main disk 710 is in place, the third positioning post 120 extends forward, passes through the corresponding slot 620, and inserts into the third positioning groove 740 to fix the main disk 710, allowing medical personnel to easily view the contents of the main disk 710 and the auxiliary disks 720. When it is necessary to switch the display content of the display disk 10, hold the hand column 440 and rotate the dosage disk 400. Under the pressure of the bottom surface of the third positioning groove 740, the third positioning post 120 gradually exits the third positioning groove 740. The main disk 710 moves inward under the action of the second elastic element 740. During the movement of the main disk 710, the two auxiliary disks 720 also retract into the interior of the main disk 710. The third positioning post 120 also gradually exits the slot 620 under the pressure of the inclined surface of the slot 620.

[0069] In some embodiments of this utility model, such as Figure 4 As shown, each expansion disk has multiple second dividing protrusions 800 on its front side. Each second dividing protrusion 800 extends radially along the dosing disk 400 and is movably arranged in the radial direction of the dosing disk 400. Each main disk 710 and auxiliary disk 720 has an arc-shaped groove at its inner end, and each second dividing protrusion 800 has a driving cylinder at its inner end, with the rear end of each driving cylinder inserted into the arc-shaped groove. As the main disk 710 and auxiliary disk 720 move radially outward along the dosing disk 400, the arc-shaped groove drives the driving cylinder, which in turn drives the second dividing protrusions 800 to move radially outward along the dosing disk 400. A guide groove 450 is provided on the rear side of the dosing disk, and the second dividing protrusions are located within the guide groove. This arrangement facilitates the division of the expansion disk into multiple display areas using multiple second dividing protrusions 800, making it easier to clearly see the content on the expansion disk.

[0070] In some embodiments of this invention, each main disc 710 has a handle groove 750 at the outer end of its front surface, and a clearance window 570 is provided in the corresponding area of ​​the dosage disc 400. This arrangement facilitates medical personnel to insert their hands into the handle groove 750, pull out the main disc 710, and the two auxiliary discs 720 will open naturally.

[0071] Of course, in some embodiments of this utility model, such as Figure 4 As shown, the outer end of the front surface of each main plate 710 may not have a handle groove.

[0072] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
