Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary equipment, and in particular to an automatic paper output device for ultrasonic examination. Background Art

[0002] When performing ultrasound examinations, ultrasound physicians are accustomed to frequently extracting paper with their left hand, using it to wipe off the ultrasound coupling gel and to pass it to patients for cleaning. When a pack of paper designed specifically for ultrasound examinations is first used, the extraction process is relatively smooth because the paper has not yet been squeezed. However, this specialized paper is not only thicker per sheet, but also comes in larger quantities per pack, making it different from the thin paper used in everyday households. As the paper is used, the difficulty of extracting the paper increases significantly when reaching the middle and lower parts of the pack, forcing the physician to repeatedly try to grasp it. This repetitive action can damage muscles and tendons, causing strain and exacerbating the damage to the left hand, which already requires repeated daily operation of the ultrasound machine panel.

[0003] However, existing paper dispensers take up a lot of space or need to be attached to a vertical wall. Since the ultrasound operating table also needs to be placed on other items, the table cannot provide placement space and vertical mounting surface for existing paper dispensers. Therefore, existing paper dispensers cannot meet the more flexible paper extraction needs for ultrasound examinations. Utility Model Content

[0004] The purpose of this application is to provide an automatic paper dispensing device for ultrasonic examination, which can more flexibly adapt to different working environments and usage requirements, improve paper extraction efficiency, and avoid muscle strain in the user's hands.

When the thickness of the paper decreases, the controller controls the rotation of the drive motor, and the rotation of the drive motor drives the rotation of the drive gear. During the rotation of the drive gear, the drive rack applies a reaction force to the drive gear to make the drive motor and the lifting plate approach the first paper output roller pair.

[0011] In one embodiment, the paper output assembly further includes a second pair of paper output rollers, which are arranged in the shell for conveying the paper on the lifting plate to the first pair of paper output rollers, and a plurality of paper pickup papers are circumferentially spaced on the axial surface of the second pair of paper output rollers.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] In the description of this application, it should be noted that the terms "inner" and "outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0034] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] The embodiment of the present application provides an automatic paper outlet device for ultrasonic examination, comprising a rack 100, a shell 200 and a paper outlet assembly 300.

[0036] The shell 200 is detachably mounted on the rack 100, the shell 200 is used for storing paper 480, and the shell 200 is provided with a paper outlet 210.

[0037] The paper outlet assembly 300 comprises a first paper outlet pair of rollers 310, the first paper outlet pair of rollers 310 is mounted in the shell 200 and located at the paper outlet 210, and the first paper outlet pair of rollers 310 rotates to drive the paper 480 in the shell 200 to be discharged from the paper outlet 210.

[0038] Through the movement or fixed setting of the rack 100, the doctor can adjust the position of the device according to the actual use demand, so as to provide more comfortable use experience. This design avoids the inconvenience of using the traditional ultrasonic examination paper towel due to improper height or position, and also reduces the problem of occupying the desktop space, so that the working environment is more clean and efficient.

[0039] The design of the paper outlet assembly 300 realizes the automatic discharge of the paper 480, especially through the rotation of the first paper outlet pair of rollers 310 to drive the paper 480 to be discharged from the paper outlet 210. This not only simplifies the process of replacing and managing the paper 480, but also improves the work efficiency and reduces the hand muscle strain.

[0040] Due to the detachable connection design between the shell 200 and the rack 100, the shell 200 can be placed on the desktop for use, or placed on the ground through the rack 100. The device can flexibly adapt to different working environments and use demands, and can meet the individual needs of different doctors and patients.

[0041] As shown in Figure 4 and Figure 6 In one embodiment, a paper taking gap 320 is arranged on the shaft surface of the first paper outlet pair of rollers 310.

[0042] As shown in Figure 6As shown, multiple papers 480 are provided and stacked on each other. The paper 480 on the upper layer is closer to the first paper-exiting roller 310 than the paper 480 on the lower layer. The paper 480 on the upper layer is limited to the paper 480 on the lower layer and is pulled out of the housing 200 by the first paper-exiting roller 310. For the convenience of understanding and describing the technical solution of the present application, two papers 480 are set as an example. The paper 480 on the upper layer is called the first paper, and the paper 480 on the lower layer is called the second paper. The first paper is pulled out by the first paper-exiting roller 310 before the second paper. In the process of the first paper-exiting roller 310 pulling out the first paper, as shown in FIG. Figure 6 As shown, in the actual process, a gap will be generated between the first paper pulling and the second paper pulling. If the paper picking gap 320 is not set on the surface of the roller group 490, as shown in FIG. Figure 5 As shown, the second paper drawing may be peeled off from the first paper drawing by the axial surface of the roller group 490, resulting in the inability to continuously draw paper. In this application, as shown in FIG. Figure 6 As shown, by setting the paper pickup gap 320, the side wall of the paper pickup gap 320 will push the second paper pulling roller to approach the first paper output roller 310, which to a certain extent curbs the problem of discontinuous paper output.

[0043] The provision of the paper pickup gap 320 effectively prevents the lower sheet 480 (the second sheet withdrawal) from being separated from the upper sheet 480 by the axial surface of the roller assembly 490 during the withdrawal of the upper sheet 480 (the first sheet withdrawal). The sidewalls of the paper pickup gap 320 push the second sheet withdrawal toward the first paper discharge rollers 310, thereby reducing the gap between the sheets 480 and preventing the lower sheet 480 from being accidentally withdrawn and interrupting the continuous paper discharge process.

[0044] The provision of the paper pickup gap 320 ensures that the paper 480 can be drawn out sequentially and continuously, thereby avoiding paper discharging interruption caused by the paper 480 being peeled off, thereby improving the overall paper discharging efficiency.

[0045] like Figures 2 to 4 As shown, in one embodiment, the paper discharge assembly 300 further includes a lifting plate 350, which is slidably installed in the shell 200, and the paper 480 in the shell 200 is placed on the lifting plate 350. The sliding of the lifting plate 350 can drive the paper 480 to approach the first paper discharge roller 310. Even if the paper 480 is gradually pulled out and the thickness decreases, as the lifting plate 350 slides, the top layer of paper 480 can still maintain a fixed distance from the first paper discharge roller 310, thereby improving the paper discharge reliability.

[0046] The design of the lifting plate 350 allows it to slide and adjust its position even if the paper 480 is stacked on it and its thickness decreases as the paper 480 is withdrawn, ensuring that the topmost paper 480 always maintains a fixed distance from the first paper discharge roller pair 310. This dynamic adjustment ensures that the paper 480 can be withdrawn smoothly and continuously, thereby improving paper discharge reliability.

[0047] By sliding the lifting plate 350 , it can be ensured that the paper 480 always maintains a certain tension during the extraction process. The stable tension of the paper 480 helps to avoid problems such as paper jams and wrinkles.

[0048] like Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, the paper output assembly 300 further includes a driving rack 360 and a driving motor 370 .

[0049] The driving rack 360 is installed in the housing 200. For example, the driving rack 360 is fixed to the inner wall of the housing 200 by gluing, welding, clamping or bolting. The driving rack 360 is installed along the moving direction of the lifting plate 350.

[0050] The drive motor 370 is fixedly mounted on the lifting plate 350. For example, the drive motor 370 is fixed to the lifting plate 350 by gluing, welding, clamping, or bolting. A drive gear 380 is provided on the output shaft of the drive motor 370, and the drive gear 380 on the drive motor 370 meshes with the drive rack 360. The forward rotation of the drive motor 370 drives the drive gear 380 to rotate forward. During the forward rotation, the drive gear 380 meshes with the drive rack 360. The drive rack 360 is fixed in position. The drive rack 360 exerts a reaction force on the drive gear 380, causing the drive gear 380 and the drive motor 370 to approach the first paper discharge roller 310. The engagement of the drive gear 380 on the output shaft of the drive motor 370 with the drive rack 360 drives the lifting plate 350 toward the first paper discharge roller 310, thereby ensuring that the top sheet of paper 480 always maintains a fixed distance from the first paper discharge roller 310.

[0051] Illustratively, the drive motor 370 rotates in the opposite direction, driving the drive gear 380 to rotate in the opposite direction. During the reverse rotation of the drive gear 380, the drive rack 360 applies a reaction force to the drive gear 380, causing the drive gear 380 and the drive motor 370 to move away from the first paper output roller 310. The drive motor 370 moves to drive the lifting plate 350 away from the first paper output roller 310, so as to increase the distance between the lifting plate 350 and the first paper output roller 310, thereby facilitating the addition of paper 480.

[0052] like Figure 8 As shown, in one embodiment, a slot 352 is provided on the lifting plate 350, and the slot 352 matches the driving rack 360, so that the inner wall of the slot 352 of the lifting plate 350 slides with the side wall of the driving rack 360, and then the lifting plate 350 is guided to move along the driving rack 360 through the side wall of the driving rack 360.

[0053] The matching design of the slot 352 and the driving rack 360 enables the lifting plate 350 to be precisely guided by the side wall of the driving rack 360 during movement, thereby avoiding shaking or deviation of the lifting plate 350 during movement and improving the stability and accuracy of its movement.

[0054] like Figure 3 and Figure 4 As shown, in one embodiment, the automatic paper discharging device for ultrasonic inspection further includes a controller and a distance sensor 400 .

[0055] The controller is electrically connected to the drive motor 370 and can control the forward and reverse rotation of the drive motor 370 . For example, the controller is a central processing unit (CPU), a programmable logic controller (PLC), or an electronic device with logic control functions.

[0056] A distance sensor 400 is installed in the housing 200 to detect the thickness of the paper 480 on the lifting plate 350 and convert the detection result into an electrical signal to be transmitted to the controller. As the paper is continuously drawn out of the housing, the distance between the remaining paper and the distance sensor gradually increases. When the distance sensor detects that the paper is moving away, it determines that the paper thickness has decreased. When the thickness of the paper 480 decreases, the controller controls the drive motor 370 to rotate forward. This forward rotation of the drive motor 370 drives the drive gear 380 to rotate. During the forward rotation of the drive gear 380, the drive rack 360 applies a reaction force to the drive motor 370, causing the drive motor 370 and the lifting plate 350 to move closer to the first paper output roller 310, ensuring that the top sheet of paper 480 always maintains a fixed distance from the first paper output roller 310. This dynamic adjustment ensures that the paper 480 can be drawn out smoothly and continuously, thereby improving paper output reliability.

[0057] Exemplarily, the distance sensor 400 includes, but is not limited to: an optical displacement sensor, an infrared distance sensor, a radar distance sensor, or a laser distance sensor.

[0058] Exemplarily, the automatic paper dispensing device for ultrasonic examination further includes an interactive component electrically connected to the controller, through which a user interacts with the controller; the interactive component includes, but is not limited to, a touch screen, buttons, or knobs. When paper 480 is exhausted, the user uses the interactive component to cause the controller to control drive motor 370 to rotate in the reverse direction, moving lift plate 350 away from first paper dispensing roller pair 310. This increases the distance between lift plate 350 and first paper dispensing roller pair 310, making it easier to refill paper 480.

[0059] The distance sensor 400 detects the thickness of the paper 480 on the lifting plate 350 in real time, converts the detection result into an electrical signal, and transmits it to the controller. The controller controls the forward and reverse rotation of the drive motor 370 based on the signal, thereby dynamically adjusting the position of the lifting plate 350. This arrangement ensures that the topmost layer of paper 480 always maintains a fixed distance from the first paper discharge roller pair 310. Even if the thickness of the stack of paper 480 changes, the paper 480 can be smoothly and continuously extracted, avoiding paper jams and paper discharge problems, and improving the reliability and stability of paper discharge.

[0060] like Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, the paper discharge assembly 300 further includes a second paper discharge roller pair 330, which is disposed in the housing 200 and is used to transport the paper 480 on the lifting plate 350 to the first paper discharge roller pair 310. A plurality of paper feed plates 340 are circumferentially spaced apart on the axial surface of the second paper discharge roller pair 330. The gaps between the paper feed plates 340 can also play the same role as the paper feed gaps. Figure 7 As shown, the second paper-discharging roller pair 330 can convey the paper 480 to the first paper-discharging roller pair 310. The second paper-discharging roller pair 330 can ensure that the first paper puller and the second paper puller remain in contact during the conveying process, and prevent the second paper puller from being separated from the first paper puller due to factors such as gravity during the conveying process, resulting in a discontinuous paper discharge process.

[0061] In one embodiment, Figure 2 As shown, the housing 200 is provided with a paper feed port 220. Figure 9 As shown, a sliding groove 230 is provided on the side wall of the paper inlet 220 .

[0062] The automatic paper discharging device for ultrasonic examination further includes a sliding door 450 , which is slidably installed in the slide groove 230 . The sliding door 450 is pulled to open or close the paper feed port 220 .

[0063] For example, a handle is provided on the sliding door 450, which can prevent the sliding door 450 from slipping out of the slide groove 230 and can restrict the sliding door 450 in the slide groove 230. For example, the handle is fixed to the sliding door 450 by gluing, welding, clamping or bolting.

[0064] The design of the sliding door 450 allows the user to easily open or close the paper feed port 220 , thereby conveniently loading new paper 480 .

[0065] When paper 480 is not needed to be loaded or replaced, the sliding door 450 can tightly close the paper inlet 220, preventing dust, dirt, or other debris from entering the device, keeping the device clean and the internal mechanical components operating normally. Furthermore, closing the paper inlet 220 can reduce safety risks caused by accidental contact or misoperation.

[0066] like Figure 2 As shown, in one embodiment, the rack 100 includes a chassis 110 , a telescoping pole 120 , and a storage platform 130 .

[0067] The telescopic rod 120 is capable of extending and retracting, and one end of the telescopic rod 120 is mounted on the chassis 110. Exemplarily, the telescopic rod 120 includes, but is not limited to, a hydraulic telescopic rod 120, a pneumatic telescopic rod 120, an electric push rod, a threaded screw mechanism, etc. Exemplarily, one end of the telescopic rod 120 is mounted on the chassis 110 by welding, gluing, clamping, or bolting.

[0068] The storage platform 130 is provided at the other end of the telescopic rod 120. For example, one end of the telescopic rod 120 is connected to the storage platform 130 by welding, gluing, clamping or bolting. The telescopic rod 120 is extended and retracted to drive the storage platform 130 to rise and fall.

[0069] like Figure 1 As shown, the storage platform 130 has a storage space capable of storing paper 480 and the like.

[0070] like Figure 1 As shown, the storage platform 130 provides an installation base for the shell 200, and the telescopic rod 120 is extended and retracted to drive the storage platform 130 and the shell 200 to rise and fall. The height of the shell 200 is adjusted by raising and lowering the telescopic rod 120, so as to adjust the height of the paper outlet 210, thereby improving adaptability.

[0071] like Figure 2 As shown, in one embodiment, the rack 100 includes universal wheels 140 , which are mounted on the chassis 110 to facilitate movement of the rack 100 .

[0072] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0073] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
