Description

Technical Field

[0001] This invention belongs to the field of storage technology, and specifically relates to a quantitative storage device for topical medications. Background Technology

[0002] Topical medications are widely used in various medical fields such as dermatology, surgery, and rheumatology, and are commonly used to treat various skin diseases, pain, and inflammation. Currently, the most common packaging for topical medications on the market is a soft tube, which requires squeezing the tube to dispense the medication before applying it to the affected area. However, this packaging and usage method has significant drawbacks: users find it difficult to precisely control the amount of medication dispensed each time, relying mainly on experience and feel. Excessive force can lead to too much medication being dispensed, resulting in waste, while insufficient force may result in an insufficient dosage, affecting the treatment effect. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quantitative storage device for topical medications. This application uses the cooperation of a rotating arm, a push rod, a sliding frame, a pull rod, and a squeezing element to adjust the internal space of the storage tube, thereby achieving the purpose of quantitative medication storage. Patients can select a sufficient amount of medication to apply as needed, which not only prevents medication waste but also ensures the therapeutic effect of the medication on the patient.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A quantitative storage device for topical medication includes a storage tube, a base plate, a housing, and an adjusting component. The storage tube is disposed on top of the base plate, and a squeezing component is disposed inside the storage tube. The adjusting component includes a fixed frame, a rotating arm, a push rod, a sliding frame, and a pulling rod. The fixed frame is set on the outer wall of the storage tube. The rotating arms are symmetrically arranged on both sides of the storage tube. One end of the rotating arm is rotatably mounted on the fixed frame, and a connecting shaft is set on the other end of the rotating arm. One end of the push rod is connected to the connecting shaft. A strip hole is opened on the side wall of the storage tube. One end of the push rod passes through the strip hole on the storage tube and is connected to the extruder. The sliding frame is slidably set on the storage tube. The two ends of the pulling rod are respectively connected to the connecting shaft and the sliding frame. Pushing the sliding frame causes one end of the pulling rod to move. The other end of the pulling rod will pull the end of the rotating arm with the connecting shaft mounted to move closer to the storage tube. When the connecting shaft moves, it will cause one end of the push rod to move closer to the storage tube. The other end of the push rod will push the extruder to move inside the storage tube, thus completing the adjustment of the storage space inside the storage tube. The housing is located on top of the base plate and outside the storage tube and the adjusting component. A locking component is also fixedly installed on the sliding frame, and the locking component cooperates with the housing to fix the sliding frame.

[0005] Preferably, the adjusting component further includes a guide plate, which is symmetrically arranged on both sides of the storage tube. The two ends of the guide plate are respectively installed on the inner wall of the storage tube and the shell. A guide hole is opened in the middle of the guide plate, and the connecting shaft is arranged in the guide hole. The guide plate is arc-shaped, and the center of the guide plate coincides with the hinge of the rotating arm and the fixed frame. The guide plate can guide the movement of the connecting shaft and prevent the connecting shaft and the rotating arm from shaking during rotation, thus ensuring the stability of the rotating arm during operation.

[0006] Preferably, a guide rail is fixedly installed on the outer wall of the storage tube, and a guide groove is opened on the inner wall of the sliding frame. The guide groove slides in conjunction with the guide rail. The guide rail can guide the sliding frame and ensure that the sliding frame moves normally up and down along the storage tube.

[0007] Preferably, the extrusion component includes an extrusion plate with an installation groove inside. Clearance holes are provided on both opposite side walls of the installation groove. The clearance holes cooperate with a push rod. An adjustment plate is also provided inside the installation groove, with both ends of the adjustment plate slidably disposed within the clearance holes. The push rod is connected to the adjustment plate. The extrusion plate, in conjunction with the adjustment component, can adjust the internal space of the storage tube, thereby achieving the purpose of quantitative drug storage.

[0008] Preferably, a fixed plate is provided in the middle of the adjusting plate, and adjusting holes are provided on both side walls of the fixed plate. A guide rod and a sliding block are provided in the adjusting holes. The sliding blocks on both sides of the fixed plate are located at both ends of the fixed plate. The two ends of the guide rod are fixedly installed on the two inner walls of the adjusting holes. The sliding blocks are slidably disposed in the adjusting holes and are slidably connected to the guide rods. The arrangement of the adjusting holes, guide rods, and sliding blocks can ensure the normal pushing operation of the push rod and prevent the side walls of the strip hole from contacting the push rod and causing interference, thus greatly ensuring the normal operation of the device.

[0009] Preferably, a spring is also provided in the adjustment hole, the spring is sleeved on the guide rod, and the end of the push rod is rotatably connected to the sliding block. The spring can provide a pushing force to the sliding block.

[0010] Preferably, a guide rod, an adjusting block, and a threaded rod are also provided in the mounting groove. Side ears are provided on both sides of the middle portion of the adjusting plate. The guide rod and threaded rod are symmetrically arranged on both sides of the adjusting plate. A fixing seat is also provided on the inner wall of the mounting groove, symmetrically arranged on both sides of the adjusting plate. The two ends of the guide rod are connected to the inner wall of the mounting groove and the fixing seat, respectively. The side ear on one side of the guide rod is slidably connected to the guide rod. The two ends of the threaded rod are rotatably connected to the inner wall of the mounting groove and the fixing seat, respectively. The end of the threaded rod extends through the fixing seat to the other side of the fixing seat. The side ear on one side of the threaded rod is connected to the threaded rod. The adjusting block is fixedly installed at the end of the threaded rod. The adjusting block facilitates the rotation of the threaded rod by the operator, improving the rotation efficiency of the threaded rod. The threaded rod enables the adjustment of the space within the storage tube. Rotating the threaded rod causes relative movement between the adjusting plate and the extrusion plate, thereby increasing the adjustment range of the space within the storage tube and ensuring the normal operation of the storage tube.

[0011] Preferably, the locking component includes a push block and a handle. The push block is symmetrically arranged on both sides of the sliding frame. A fixing groove is formed on the push block. Inside the fixing groove, a rotating shaft, a gear, an upper rack, a lower rack, and a limiting plate installed at the end of the rack are arranged. The rotating shaft is rotatably installed in the fixing groove, and one end of the rotating shaft passes through the push block and extends to the outside of the push block. The handle is located on the outside of the push block and is fixedly installed on the rotating shaft. The gear is fixedly installed on the rotating shaft. The upper rack and lower rack are symmetrically arranged on the upper and lower sides of the gear, and both the upper rack and lower rack mesh with the gear. The sliding frame has a strip-shaped through hole on its shell. The push block is slidably positioned inside the strip-shaped through hole, and the limiting plate cooperates with the strip-shaped through hole. The locking component is used to lock the sliding frame to prevent it from moving up and down during drug storage, thus ensuring the accuracy of the drug storage quantity in the storage tube. By turning the handle, the rotating shaft is driven to rotate, which in turn drives the gear to rotate. The gear rotation simultaneously drives the upper and lower racks to move outward. During the outward movement of the upper and lower racks, the limiting plate is driven to move outward until the limiting plate contacts the strip-shaped through hole, thereby achieving the purpose of fixing the sliding frame.

[0012] Preferably, several limiting grooves are evenly opened on both sides of the strip-shaped through hole. The limiting grooves cooperate with the limiting plate. The setting of the limiting grooves can limit the limiting plate and ensure the normal locking operation of the locking component.

[0013] Preferably, an upper slide rail and a lower slide rail are also fixedly installed on the fixed groove. Slide grooves are opened on both the upper rack and the lower rack. The slide groove on the upper rack slides in cooperation with the upper slide rail, and the slide groove on the lower slide rail slides in cooperation with the lower rack. The upper slide rail and the lower slide rail can guide the upper rack and the lower rack, prevent the upper rack and the lower rack from shaking during movement, and ensure the normal operation of the locking parts.

[0014] The beneficial effects of this invention are: 1) This device can adjust the internal space of the storage tube through the cooperation of the rotating arm, push rod, sliding frame, pull rod and squeezing component, so as to achieve the purpose of quantitative storage of drugs. Patients can choose to apply a sufficient amount of drugs as needed, which not only prevents waste of drugs, but also ensures the therapeutic effect of drugs on patients.

[0015] 2) The guide plate of this device can guide the movement of the connecting shaft and prevent the connecting shaft and the rotating arm from shaking during rotation, thus ensuring the stability of the rotating arm during operation.

[0016] 3) The guide rail of this device can guide the sliding frame and ensure that the sliding frame moves up and down normally along the storage tube.

[0017] 4) The two ends of the adjustment plate of this device are slidably set in the clearance hole. The push rod is connected to the adjustment plate and the squeezing plate, together with the adjustment component, can adjust the internal space of the storage tube, thereby achieving the purpose of quantitative storage of drugs.

[0018] 5) The adjustment hole, guide rod, and sliding block of this device can ensure the normal pushing operation of the push rod and prevent the side wall of the strip hole from contacting the push rod and causing interference, thus greatly ensuring the normal operation of the device.

[0019] 6) The device is also equipped with a spring in the adjustment hole. The spring is sleeved on the guide rod, and the end of the push rod is rotatably connected to the sliding block. The spring can provide a pushing force to the sliding block.

[0020] 7) The adjustment block of this device facilitates the rotation of the threaded rod by the operator, improves the rotation efficiency of the threaded rod, and enables the extension and adjustment of the space inside the storage tube. The relative movement between the adjusting plate and the extrusion plate when the threaded rod is rotated increases the adjustment range of the space inside the storage tube, thus ensuring the normal operation of the storage tube.

[0021] 8) The locking mechanism of this device is used to lock the sliding frame to prevent it from moving up and down during drug storage, thus ensuring the accuracy of the drug storage quantity in the storage tube. By turning the handle, the rotating shaft is driven to rotate, which in turn drives the gear to rotate. The gear rotation simultaneously drives the upper and lower racks to move outward. During the outward movement of the upper and lower racks, the limiting plate is driven to move outward until the limiting plate contacts the strip-shaped through hole, thereby achieving the purpose of fixing the sliding frame.

[0022] 9) Several limiting grooves are evenly opened on both sides of the strip-shaped through hole. The limiting grooves cooperate with the limiting plate. The setting of the limiting grooves can limit the limiting plate and ensure the normal locking operation of the locking parts.

[0023] 10) The upper and lower slide rails of this device can guide the upper and lower racks, prevent them from shaking during movement, and ensure the normal operation of the locking components. Attached Figure Description

[0042] In this embodiment, as Figure 5 As shown, the extrusion member 6 includes an extrusion plate 601, with an installation groove 6014 inside the extrusion plate 601. Clearance holes 602 are provided on both opposite side walls of the installation groove 6014. The clearance holes 602 cooperate with the push rod 408. An adjustment plate 605 is also provided inside the installation groove 6014. The two ends of the adjustment plate 605 are slidably disposed within the clearance holes 602. The push rod 408 is connected to the adjustment plate 605. The extrusion plate 601, in conjunction with the adjustment member 4, can adjust the internal space of the storage tube 3, thereby achieving the purpose of quantitative drug storage.

[0043] In this embodiment, as Figure 7 As shown, a fixed plate 6012 is provided in the middle of the adjusting plate 605. Adjusting holes 6010 are provided on both sides of the fixed plate 6012. A guide rod 609 and a sliding block 6011 are provided in the adjusting holes 6010. The sliding blocks 6011 on both sides of the fixed plate 6012 are located at both ends of the fixed plate 6012.

[0047] In this embodiment, as Figure 8 , Figure 9 As shown, the locking component 5 includes a push block 501 and a handle 505. The push block 501 is symmetrically arranged on both sides of the sliding frame 405. A fixing groove 502 is formed on the push block 501. Inside the fixing groove 502, a rotating shaft 504, a gear 503, an upper rack 5011, a lower rack 506, and a limiting plate 509 installed at the end of the rack are arranged. The rotating shaft 504 is rotatably installed in the fixing groove 502, and one end of the rotating shaft 504 extends through the push block 501 to the outside of the push block 501. The handle 505 is located on the outside of the push block 501 and is fixed. The gear 503 is fixedly mounted on the rotating shaft 504. The upper rack 5011 and the lower rack 506 are symmetrically arranged on the upper and lower sides of the gear 503, and both the upper rack 5011 and the lower rack 506 mesh with the gear 503. A strip-shaped through hole 201 is opened on the housing 2. The pushing block 501 is slidably arranged in the strip-shaped through hole 201, and the limiting plate 509 cooperates with the strip-shaped through hole 201. The locking member 5 is used to lock the sliding frame 405 to prevent the sliding frame 405 from moving up and down during the storage of drugs, thus ensuring the accuracy of the storage amount of drugs in the storage tube 3.

[0048] By rotating the handle 505, the rotating shaft 504 is driven to rotate. The rotation of the rotating shaft 504 drives the gear 503 to rotate. The rotation of the gear 503 simultaneously drives the upper rack 5011 and the lower rack 506 to move outward. During the outward movement of the upper rack 5011 and the lower rack 506, the limiting plate 509 is driven to move outward until the limiting plate 509 contacts the strip-shaped through hole 201, thereby achieving the purpose of fixing the sliding frame 405.

[0049] In this embodiment, as Figure 1 As shown, several limiting grooves 202 are evenly opened on both sides of the strip-shaped through hole 201. The limiting grooves 202 cooperate with the limiting plate 509. The setting of the limiting grooves 202 can limit the limiting plate 509 and ensure the normal locking operation of the locking part 5.

[0050] In this embodiment, as Figure 9 As shown, an upper slide rail 5010 and a lower slide rail 508 are also fixedly installed on the fixed groove 502. Slide grooves 507 are opened on both the upper rack 5011 and the lower rack 506. The slide groove 507 on the upper rack 5011 slides in cooperation with the upper slide rail 5010, and the slide groove 507 on the lower slide rail 508 slides in cooperation with the lower rack 506. The upper slide rail 5010 and the lower slide rail 508 can guide the upper rack 5011 and the lower rack 506, prevent the upper rack 5011 and the lower rack 506 from shaking during movement, and ensure the normal operation of the locking part 5.

[0051] Staff can determine the size of the space inside the storage tube 3 by observing the interaction between the limiting plate 509 and the limiting grooves 202 at different positions on the strip-shaped through hole 201.

[0052] The adjustment process is as follows: Pushing the push block 501 along the strip-shaped through hole 201 causes the sliding frame 405 to move along the storage tube 3. The movement of the sliding frame 405 causes one end of the pull rod 404 to move. The other end of the pull rod 404 then pulls the end of the rotating arm 403 with the connecting shaft 407 mounted thereon to move closer to the storage tube 3. As the connecting shaft 407 moves, it causes one end of the push rod 408 to move closer to the storage tube 3. The other end of the push rod 408 pushes the extruder 6 to move inside the storage tube 3, thereby achieving the purpose of adjusting the internal space of the storage tube 3. After the adjustment is completed, turn the handle 505 to drive the rotating shaft 504 to rotate. The rotation of the rotating shaft 504 will drive the gear 503 to rotate. The rotation of the gear 503 will drive the upper rack 5011 and the lower rack 506 to move simultaneously toward the limiting groove 202 on the side wall of the strip-shaped through hole 201, until the limiting plate 509 extends into the limiting groove 202, thereby fixing the sliding frame 405.

[0053] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
