Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a pressing device for irregularly shaped adhesive tape. Background Technology

[0002] Medical adhesive tape is a common medical aid, often used to fix catheters, items, and bandage wounds. It is usually an adhesive tape with a self-adhesive backing, and some tapes have a protective layer on the adhesive side. With the rapid development of medical technology and the increasing diversity of patient needs, the demand for various shaped adhesive tapes in clinical work has increased dramatically to meet different clinical scenarios and uses. These shaped adhesive tapes are not only used for fixing drainage tubes and endotracheal tubes in daily life, but also widely used for fixing medical devices, protection, and auxiliary support during rehabilitation. They are an indispensable consumable in medical practice.

[0003] Pre-made adhesive tape is expensive and its shape is fixed and not easily changed. Traditional tape cutting mainly relies on manual operation by medical staff. Although this process seems simple, it is actually time-consuming and labor-intensive, especially in emergency treatment or when there are many patients. Medical staff need to spend a lot of time cutting and preparing tape, which not only reduces work efficiency but also distracts them from direct patient care, affecting the quality and efficiency of medical services. Summary of the Invention

[0018] The main benefits of this application are:

[0019] 1. First, wrap the protective tape around the No. 2 drive shaft, and then wrap one end of the tape around the bottom of the roller and extend it through the other side of the arc groove. Then, install the fixing cover on the base. At this time, the fixing plate, telescopic motor and pressing plate are located inside the roller. Start the telescopic motor to make the pressing plate squeeze the pressing plate, which in turn causes the pressing plate to drive the pressing mold installed on it to press the tape, thereby realizing the adjustment of the tape shape.

[0020] 2. When it is necessary to change the shape of the irregularly shaped adhesive tape, start motor number one. Through the continuous meshing of gear number one and gear number two, the rotation of gear number two drives the mold assembly to rotate through the roller. By placing different mold assemblies under the pressing plate, different irregularly shaped adhesive tapes can be output during subsequent pressing actions.

[0021] 3. During the pressing process, the pressing plate mainly drives the pressing mold to press the adhesive tape. The displacement distance of the pressing plate directly reflects the pressing force of the pressing mold on the adhesive tape. The distance change of the pressing plate is monitored by the first distance sensor, which in turn represents the pressing force of the pressing mold on the adhesive tape. This allows it to be adapted to the use of adhesive tape of different conditions or thicknesses, ensuring the pressing effect.

[0022] 4. The number of rotations and angles of the No. 1 gear and the output end of the No. 1 motor are consistent. Since the number of teeth of the No. 1 gear and the No. 2 gear are proportional, the rotation angle of the No. 2 gear can be determined by knowing the number of teeth of the No. 1 gear, the number of rotations of the No. 1 gear, and the angle. Therefore, by monitoring the number of rotations and angles of the output end of the No. 1 motor through the first encoder, the rotation angle of the No. 2 gear can be calculated, thereby realizing the adjustment of the position of different mold components.

[0023] 5. The second and third encoders monitor the rotation speed of the output ends of motors 2 and 3, respectively. Since motor 2 drives the transmission roller to rotate through drive shaft 1, the transmission roller will come into contact with the adhesive tape. As the transmission roller rotates, the friction between the transmission roller and the adhesive tape will cause the adhesive tape to flow out. At the same time, motor 3 drives drive shaft 2 to rotate, thereby realizing the unwinding action of the adhesive tape wound on drive shaft 2. By monitoring and controlling the rotation speed of the output ends of motors 2 and 3, the flow speed of the adhesive tape is guaranteed.

[0024] 6. Since the tape will wrap around the surface of the second drive shaft, the distance between the second drive shaft and the inner wall of the placement cavity will be shortened. The second distance sensor can monitor the distance between the second drive shaft and the inner wall of the placement cavity to determine the tape wrapping situation.

[0025] 7. The operating status of motor 1, motor 2, motor 3, first encoder, second encoder, third encoder, first distance sensor and second distance sensor will be transmitted to the controller. The controller will then transmit the data to the display screen and the wireless communication device. Users can observe the operating status by watching the display screen, and the wireless communication device will display the data on the screen, thus achieving the effect of remote monitoring.

[0044] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8In one or more embodiments, a pressing device for irregularly shaped adhesive tape is provided, comprising: a base 100, the base 100 having an arc-shaped groove 101, a cavity 102, and a connecting hole 103 inside, the cavity 102, the connecting hole 103, and the arc-shaped groove 101 being sequentially connected, a first motor 104 being disposed inside the cavity 102, the output end of the first motor 104 being connected to a first gear 105, the surface of the first gear 105 extending into the connecting hole 103, and the inner wall of the arc-shaped groove 101 being provided with... A limit plate 120 is provided. A controller 106 is installed inside the base 100, and the controller 106 is electrically connected to a first motor 104. A second gear 200 has its surface meshing with the surface of the first gear 105. The limit plate 120 abuts against the surface of the second gear 200. A roller 201 is provided on the front of the second gear 200, and a mold assembly 207 is provided on the roller 201. The mold assembly 207 includes a pressing plate 204 and a limit rod 205. The roller 201 has a... A through hole 202 and a limiting hole 203 are provided. A limiting rod 205 is disposed inside the limiting hole 203. A pressing plate 204 passes through the through hole 202 and the limiting hole 203. The pressing plate 204 is sleeved on the surface of the limiting rod 205. A return spring 206 is provided on the surface of the limiting hole 203 and outside the limiting rod 205. A pressing mold is detachably connected to the side of the pressing plate 204 facing the arc-shaped groove 101. There is a distance gap between the second gear 200 and the roller 201 and the arc-shaped groove 101. Mold assembly 2 There are multiple 07s, and the multiple pressing molds have different shapes; a fixed cover 300 is detachably connected to the base 100. A fixed plate 301 is provided on the surface of the fixed cover 300. The fixed plate 301 extends into the inner cavity of the roller 201. A telescopic motor 302 is provided at the bottom of the fixed plate 301. A pressing plate 303 is provided at the output end of the telescopic motor 302. The bottom of the pressing plate 303 can abut against the surface of the pressing plate 204. The telescopic motor 302 is electrically connected to the controller 106.

[0045] In this embodiment, the adhesive is placed on the arc-shaped groove, with one end of the adhesive extending out of the groove. Then, the second gear drives the roller 201 and the mold assembly 207 to be placed on the arc-shaped groove. The second gear is located between the limiting plates 120, and the second gear and the first gear are meshed. The fixing cover 300 is installed on the base 100. At this time, the fixing plate 301, the telescopic motor 302, and the pressing plate 303 are located inside the roller 201. The telescopic motor 302 is activated, causing the pressing plate 303 to press the pressing plate 204, which in turn causes the pressing plate 204 to drive the pressing mold installed on it to press the adhesive, thereby achieving the adjustment of the irregular shape of the adhesive. Since the pressing molds on different mold assemblies 207 have different shapes to adapt to the pressing of different shaped adhesives, when it is necessary to change the pressing shape of the irregular adhesive, the first motor 104 is activated, and the first gear 105 and the second gear 200 continuously mesh... The rotation of gear 200, in turn, drives the mold assembly 207 to rotate via roller 201. By placing the pressing plates 204 of different mold assemblies 207 below the pressing plate 303, different shaped adhesive tapes can be output during subsequent pressing actions. It should be noted that the fixed cover 300 and the base 100 are detachably connected by bolts, buckles, and other structures. The detachable connection between the pressing plate 204 and the pressing mold is mainly achieved by setting a slot on the pressing plate 204 that matches the pressing mold. A squeezing pad and other structures are set in the slot to squeeze the pressing mold inserted into the slot, thereby achieving a detachable connection, which facilitates the replacement of the pressing mold and reduces the difficulty of cleaning and disinfection. A cutting blade 121 can be set on the top of the base 100, on the side where the adhesive tape flows out. When the adhesive tape flows out, the user presses down on the adhesive tape, and the cutting blade 121 cuts the adhesive tape to meet the user's needs.

[0046] Please see Figure 1 , Figure 3 , Figure 5 and Figure 6 In some embodiments, a transmission cavity 107 is provided inside the base 100, and the transmission cavity 107 is connected to the arc-shaped groove 101. A second motor 108 is provided inside the base 100. The output end of the second motor 108 is connected to a first drive shaft 109. The other end of the first drive shaft 109 is movably connected to the inner wall of the transmission cavity 107. A transmission roller 110 is provided on the surface of the first drive shaft 109, and the surface of the transmission roller 110 extends into the interior of the arc-shaped groove 101.

[0047] In this embodiment, the second motor 108 drives the transmission roller 110 to rotate via the first drive shaft 109. The transmission roller 110 comes into contact with the adhesive tape. As the transmission roller 110 rotates, the adhesive tape flows out under the action of friction. The transmission roller 110 has anti-slip textures or anti-slip particles to increase friction and ensure stable flow of the adhesive tape.

[0048] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 9 In some embodiments, the base 100 has a placement cavity 111 and a limiting groove 112 inside. The limiting groove 112 and the arc-shaped groove 101 are both connected to the placement cavity 111. A third motor 113 is installed inside the base 100. The output end of the third motor 113 is connected to a second drive shaft 114. A compression spring 115 is installed inside the limiting groove 112. A clamping plate 116 is installed inside the limiting groove 112. One side of the clamping plate 116 extends into the limiting groove 112. The surface of the compression spring 115 abuts against the surface of the clamping plate 116. One side of the clamping plate 116 is sleeved on the surface of the second drive shaft 114. There are at least two clamping plates 116. The third motor 113 and the controller 106 are electrically connected.

[0049] In this embodiment, after one end of the adhesive tape is fixed to the second drive shaft 114, the third motor 113 is started to rotate the drive shaft, thereby causing the adhesive tape to be rolled onto the second drive shaft 114. During this process, the elastic force of the compression spring 115 is used to compress the adhesive tape through the clamping plate 116, thereby restricting the position of the adhesive tape. When the third motor 113 causes the second drive shaft 114 to rotate in the opposite direction, the unwinding action of the adhesive tape is achieved.

[0050] Please see Figure 1 , Figure 8 and Figure 10 In some embodiments, a first distance sensor is provided inside the fixing plate 301. The first distance sensor is used to monitor the distance change of the pressing plate 204. The first distance sensor is electrically connected to the controller 106.

[0051] In this embodiment, the pressing process mainly relies on the pressing plate 204 to drive the pressing mold to press the adhesive tape. The displacement distance of the pressing plate 204 directly represents the pressing force of the pressing mold on the adhesive tape. The distance change of the pressing plate 204 is monitored by the first distance sensor, which in turn represents the pressing force of the pressing mold on the adhesive tape. This allows it to be adapted to the use of adhesive tape of different thicknesses or under different conditions, ensuring the pressing effect.

[0052] Please see Figure 1 , Figure 3 andFigure 10 In some embodiments, a first encoder is provided on the surface of the first motor 104. The first encoder is used to monitor the number of rotations and angle of the output end of the first motor 104. The teeth of the first gear 105 and the second gear 200 are proportional. The first encoder is electrically connected to the controller 106.

[0053] In this embodiment, the number of rotations and angles of the output end of the first gear 105 and the first motor 104 are consistent. Since the number of teeth of the first gear 105 and the second gear 200 are proportional, the rotation angle of the second gear 200 can be determined by knowing the number of teeth, the number of rotations and the angle of the first gear 105. Therefore, by monitoring the number of rotations and the angle of the output end of the first motor 104 through the first encoder, the rotation angle of the second gear 200 can be calculated, thereby enabling the adjustment of the positions of different mold components 207.

[0054] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 10 In some embodiments, a second encoder is provided on the surface of the second motor 108, and a third encoder is provided on the surface of the third motor 113. The second encoder is used to monitor the rotation speed of the output end of the second motor 108, and the third encoder is used to monitor the rotation speed of the output end of the third motor 113. The second encoder and the third encoder are electrically connected to the controller 106.

[0055] In this embodiment, the second encoder and the third encoder monitor the rotation speed of the output terminals of the second motor 108 and the third motor 113, respectively. Since the second motor 108 drives the transmission roller 110 to rotate through the first drive shaft 109, the transmission roller 110 will come into contact with the adhesive tape. As the transmission roller 110 rotates, the friction between the transmission roller 110 and the adhesive tape will enable the adhesive tape to flow out. At the same time, the third motor 113 drives the second drive shaft 114 to rotate, thereby enabling the adhesive tape wound on the second drive shaft 114 to unwind. By monitoring and controlling the rotation speed of the output terminals of the second motor 108 and the third motor 113, the flow speed of the adhesive tape is ensured.

[0056] Please see Figure 1 , Figure 2 , Figure 3 and Figure 10 In some embodiments, a second distance sensor is provided inside the base 100. The second distance sensor is used to monitor the distance between the surface of the second drive shaft 114 and the placement cavity 111. The second distance sensor is electrically connected to the controller 106.

[0057] In this embodiment, since the tape will wrap around the surface of the second drive shaft 114, the distance between the second drive shaft 114 and the inner wall of the placement cavity 111 will be shortened. The second distance sensor can monitor the distance between the second drive shaft 114 and the inner wall of the placement cavity 111 to know the tape wrapping situation.

[0058] Please see Figure 1 and Figure 10 In some embodiments, a display screen 117 is provided on one side of the base 100. The display screen 117 is electrically connected to the controller 106. The base 100 also includes a terminal, which includes a display and a wireless communication device. The display and the wireless communication device are electrically connected, and the controller 106 and the wireless communication device are communicatively connected.

[0059] In this embodiment, the operating status of motor 104, motor 108, motor 113, first encoder, second encoder, third encoder, first distance sensor, and second distance sensor is transmitted to controller 106. Controller 106 then transmits the data to display screen 117 and wireless communication device. Users can observe the operating status by viewing display screen 117, and the wireless communication device displays the received data on the display screen, thus achieving remote monitoring. The terminal can be a mobile phone, tablet, computer, etc., and the communication connection can be 4G, 5G, WIFI, Bluetooth, local area network, etc.

[0060] Please see Figure 1 , Figure 5 and Figure 10 In some embodiments, a battery 118 is provided inside the base 100. The battery 118 is used to power the first motor 104, the second motor 108, the third motor 113, the controller 106, the first encoder, the second encoder, the third encoder, the display screen 117, the first distance sensor and the second distance sensor. A charging hole 119 is provided on one side of the base 100.

[0061] In this embodiment, the battery 118 can power the first motor 104, the second motor 108, the third motor 113, the controller 106, the first encoder, the second encoder, the third encoder, the display screen 117, the first distance sensor, and the second distance sensor, while the battery 118 can be charged through the charging port 119.

[0062] It should be noted that the specific models and specifications of the battery 118, motor 104, motor 108, motor 113, controller 106, first encoder, second encoder, third encoder, display screen 117, first distance sensor, second distance sensor, wireless communication device, and display in this disclosure need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be described in detail here. The power supply and its principle are clear to those skilled in the art, and will not be described in detail here. The connection and installation of each part and the signal transmission principle are well known in this field.

[0063] Specifically, the working principle of the pressing device for irregularly shaped adhesive tape provided in this application is as follows:

[0064] After fixing one end of the adhesive tape to the second drive shaft 114 in advance, start the third motor 113 to make the drive shaft rotate, so that the adhesive tape is rolled up to the second drive shaft 114. The other end of the adhesive tape passes through the arc groove and is placed on the other side of the arc groove. Then, the second gear drives the roller 201 and the mold assembly 207 to be placed on the arc groove. The second gear is located between the limit plates 120, and the second gear and the first gear are meshed. The fixing cover 300 is installed on the base 100. At this time, the fixing plate 301, the telescopic motor 302 and the pressing plate 303 are located inside the roller 201.

[0065] The telescopic motor 302 is activated to cause the pressing plate 303 to press the pressing plate 204, which in turn causes the pressing plate 204 to drive the pressing mold installed on it to press the adhesive tape, thereby realizing the adjustment of the shape of the adhesive tape. Since the pressing molds on different mold components 207 have different shapes to adapt to the pressing of different shaped adhesive tapes, when it is necessary to change the pressing shape of the adhesive tape, the first motor 104 is activated. Through the continuous meshing of the first gear 105 and the second gear 200, the rotation of the second gear 200 drives the mold component 207 to rotate through the roller 201. By placing the pressing plate 204 of different mold components 207 under the pressing plate 303, the output of different shaped adhesive tapes can be realized during subsequent pressing operations.

[0066] When the adhesive tape flows out, motor 108 and motor 113 work simultaneously, which causes drive shaft 109 and drive shaft 114 to rotate. When drive shaft 114 rotates in the opposite direction, the adhesive tape is unwound. In conjunction with the transmission roller 110, the adhesive tape flows out under the action of friction during rotation. By monitoring and controlling the speed of the output ends of motor 108 and motor 113, the flow rate of the adhesive tape is ensured.

[0067] The distance change of the pressing plate 204 is monitored by the first distance sensor, which represents the pressing force of the pressing mold on the adhesive tape, and thus can be adapted to the use of adhesive tape of different conditions or different thicknesses.

[0068] By monitoring the number of rotations and angle of the output of motor 104 by the first encoder, the rotation angle of gear 200 can be calculated, thereby enabling the adjustment of the position of different mold components 207.

[0069] The distance sensor monitors the distance between the second drive shaft 114 and the inner wall of the placement cavity 111 to determine the tape wrapping situation.

[0070] The operating status of motor 104, motor 108, motor 113, first encoder, second encoder, third encoder, first distance sensor and second distance sensor will be transmitted to controller 106. Controller 106 will transmit the data to display screen 117 and wireless communication device. Users can observe the operating status by viewing display screen 117, and the wireless communication device will display the data on the display screen, thus achieving the effect of remote monitoring.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
