This invention provides a device for applying ointments for rheumatic and immunological diseases, comprising a box body with an ointment chamber at the top and a buffer chamber inside the box body, the buffer chamber having a flat opening; a control rod rotatably connected to the inner cavity of the buffer chamber, a buffer plate being provided on one side of the control rod, and a first spring connecting the buffer plate and the buffer chamber; a conveyor plate rotatably mounted inside a cylindrical chamber, the conveyor plate having multiple transfer grooves evenly distributed around its circumference; a first tube being provided on the top side of the cylindrical chamber and a second tube being provided on the bottom side; a drive mechanism capable of driving the conveyor plate to rotate. The ointment continuously flowing into the buffer chamber pushes the buffer plate towards the bottom of the buffer chamber, and the first spring also provides an elastic force that pushes the buffer plate upwards. Under the mutual pushing action of the ointment and the buffer plate, the ointment is compressed, reducing gaps and air bubbles, and is discharged from the flat opening, resulting in a uniform and dense ointment without gaps, eliminating the need for secondary coating and repair, and reducing drug waste while ensuring drug absorption.

Description

Technical Field

[0001] This invention relates to the field of drug application devices, specifically to a drug application device for rheumatic and immune diseases. Background Technology

[0002] Rheumatological and immunological diseases are a group of diseases in internal medicine, mainly including rheumatoid arthritis, ankylosing spondylitis, systemic lupus erythematosus, osteoarthritis, gout, and primary Sjögren's syndrome. Rheumatological and immunological diseases can affect multiple organs and systems, and the hematopoietic system is also frequently involved.

[0003] In the treatment of rheumatic and immunological diseases, targeted medications are used, which require applying ointments to the affected area. Currently, ointments are usually squeezed directly onto the affected area. However, it is difficult to control the amount of ointment squeezed out by hand. In addition, ointments themselves usually have many gaps and air bubbles. When applying the medication, some areas often have too much medication while others have too little or no medication, resulting in unsatisfactory drug absorption.

[0004] Therefore, there is an urgent need to develop an ointment application device that can evenly apply ointment to the affected area. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention proposes a device for applying ointments for rheumatic and immunological diseases to solve the above problems.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] The present invention provides a device for applying ointments for rheumatic and immunological diseases, comprising:

[0008] The box has an ointment compartment at the top and a buffer compartment at the bottom of the inner cavity. The bottom side of the buffer compartment has a flat opening that communicates with the outside.

[0009] A control lever is rotatably connected to the bottom of the buffer chamber near the flat opening. A buffer plate is provided on the side of the control lever away from the flat opening. The edge of the buffer plate abuts against the side wall of the buffer chamber and is connected to the bottom of the buffer chamber by a first spring.

[0010] A cylindrical container has a conveyor disc rotatably mounted inside. The edge of the conveyor disc abuts against the inner wall of the cylindrical container and is evenly distributed with multiple transfer grooves around its circumference. A first tube communicating with an ointment container is located on the top side of the cylindrical container, and a second tube communicating with the top of a buffer container is located on its bottom side.

[0011] A drive mechanism that can drive the conveyor disc to rotate.

[0012] Furthermore, the driving mechanism includes a drive shaft, a transmission shaft, and a transmission belt. The drive shaft is rotatably connected to the bottom of the inner cavity of the box. A drive wheel protruding from the bottom of the box is provided on the drive shaft. The transmission shaft is coaxially connected to the conveyor plate, and its end penetrates the side wall of the cylindrical compartment and is connected to the drive shaft via the transmission belt.

[0013] Furthermore, it also includes a balancing assembly, which includes an insert plate, a sliding seat, and connecting rods. The two ends of the control rod pass through both sides of the buffer chamber. One end of each of the two connecting rods is fixedly connected to the two protruding ends of the control rod, and the other end extends upward and is provided with a movable groove. The sliding seat is installed on the top of the inner cavity of the box. The insert plate is slidably installed on the sliding seat, with one end sliding through one side of the first tube. The other end has connectors on both sides that are slidably connected to the corresponding movable grooves. When the buffer plate rotates toward the bottom of the buffer chamber, the control rod will drive the connecting rod to push the insert plate into the first tube.

[0014] Furthermore, it also includes a locking assembly, which includes a toothed ring and a locking rod. The toothed ring is located on the outside of the drive shaft. One end of the locking rod is fixedly connected to one end of the control rod, and the other end is provided with a locking pawl. When the buffer plate rotates to the bottom of the buffer chamber, the control rod will drive the locking rod to rotate so that the locking pawl abuts against the toothed ring.

[0015] Furthermore, a push groove is provided at one end of the second tube facing the cylindrical chamber, and a push plate is slidably installed in the push groove. A second spring is connected between the push plate and the bottom of the push groove so that the push plate can press against the edge of the conveyor tray.

[0016] Furthermore, the transfer groove and the edge of the conveyor tray are connected by a rounded transition.

[0017] Furthermore, a diversion chamber is provided at the top of the buffer chamber, and multiple diversion ports communicating with the diversion chamber are opened at the top of the buffer chamber. The top of the diversion chamber is connected to the bottom end of the second tube.

[0018] Furthermore, the top of the ointment container is provided with a lid.

[0019] As can be seen from the above technical solution, the present invention provides a device for applying ointments for rheumatic and immune diseases:

[0020] 1. The ointment continuously flowing into the buffer chamber pushes the buffer plate towards the bottom of the buffer chamber, while the first spring also provides elastic force to push the buffer plate upward. Under the mutual squeezing action of the ointment and the buffer plate, the ointment will be compressed to reduce gaps and air bubbles, and will be discharged from the flat opening, so that the discharged ointment is of uniform thickness and tight without gaps, eliminating the need for secondary coating and leak repair, improving the ointment coating efficiency, and reducing drug waste while ensuring drug absorption. When the conveyor tray stops rotating, the delivery of ointment will also be interrupted.

[0021] 2. By using a balancing component, the ointment delivery is reduced when the amount of ointment in the buffer chamber increases and increased when the amount of ointment in the buffer chamber decreases. This helps to maintain a dynamic balance of the amount of ointment in the buffer chamber, achieving adaptive adjustment. This keeps the downward pressure of the ointment flowing into the buffer chamber and the upward pressure of the first spring on the buffer plate within a controllable range, ensuring stable pressure in the buffer chamber and thus ensuring that the ointment can be smoothly discharged from the flat opening.

[0022] 3. When the buffer plate rotates to the bottom of the buffer chamber, that is, when the amount of ointment in the buffer chamber reaches the storage threshold, the control lever will drive the locking lever to rotate so that the locking pawl abuts against the toothed ring. The locking pawl is locked between the teeth of the toothed ring, thereby locking the rotation of the drive wheel, stopping the rotation of the conveyor plate, and thus directly stopping the ointment delivery until the amount of ointment in the buffer chamber is reduced.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] like Figure 1-4 As shown, this embodiment provides a rheumatic immune disease ointment application device, which includes a box body 1, a control rod 2, a cylindrical chamber 3, and a drive mechanism 4.

[0037] Please see Figure 2 The top of the box body 1 is provided with an ointment container 11, which is used to hold ointment. Preferably, the top of the ointment container 11 is provided with a lid 14. Opening the lid 14 allows ointment to be added to the ointment container 11 or to balance the pressure inside the ointment container 11. A buffer chamber 12 is installed at the bottom of the inner cavity of the box body 1. The buffer chamber 12 is used to temporarily store the ointment that is about to be discharged. The ointment will enter the buffer chamber 12 from the top through the cylindrical chamber 3. A flat opening 121 communicating with the outside is opened on one side of the bottom of the buffer chamber 12. The ointment is sorted and discharged through the flat opening 121, so that the discharged ointment can be evenly and flatly applied to the affected area.

[0038] The control lever 2 is rotatably connected to the bottom of the inner cavity of the buffer chamber 12 near the flat opening 121. A buffer plate 21 is provided on the side of the control lever 2 away from the flat opening 121. The edge of the buffer plate 21 abuts against the side wall of the buffer chamber 12 to prevent the ointment from seeping below the buffer plate 21. A first spring 22 is connected between the buffer plate 21 and the bottom of the buffer chamber 12. The first spring 22 can provide elastic force to make the buffer plate 21 rotate towards the top of the buffer chamber 12. When the ointment continuously flows into the buffer chamber 12 from the top, it will push the buffer plate 21 to rotate towards the bottom of the buffer chamber 12. The buffer plate 21 will also squeeze and push the ointment above it to the flat opening 121 under the elastic force of the first spring 22. This is beneficial for squeezing and accumulating before the ointment is discharged, reducing gaps or air bubbles in the ointment, and ensuring that the ointment is discharged evenly without gaps.

[0039] The cylindrical chamber 3 is rotatably mounted with a conveyor plate 31. The edge of the conveyor plate 31 abuts against the inner wall of the cylindrical chamber 3 and is evenly distributed with multiple transfer grooves 311 around the circumference. The top side of the cylindrical chamber 3 is provided with a first tube 32 that communicates with the ointment chamber 11, and the bottom side of the cylindrical chamber 3 is provided with a second tube 33 that communicates with the top of the buffer chamber 12.

[0040] The drive mechanism 4 can drive the conveyor plate 31 to rotate.

[0041] In practical use, the ointment in the ointment container 11 falls through the first tube 32 into the transfer groove 311 on the top side of the conveyor plate 31. The drive mechanism 4 drives the conveyor plate 31 to rotate, so that each subsequent transfer groove 311 can receive the ointment in turn. When the transfer groove 311 is transferred to the top of the second tube 33, the ointment will fall into the buffer chamber 12 through the second tube 33. The ointment continuously flowing into the buffer chamber 12 will push the buffer plate 21 towards the bottom of the buffer chamber 12. At the same time, the first spring 22 also provides an elastic force to push the buffer plate 21 upward. Under the mutual squeezing action of the ointment and the buffer plate 21, the ointment will be compressed to reduce gaps and air bubbles, and will be discharged from the flat opening 121. The discharged ointment is uniform in thickness and tight without gaps, eliminating the need for secondary coating and repair, improving the ointment coating efficiency, and reducing drug waste while ensuring the drug absorption effect. When the conveyor plate 31 stops rotating, the delivery of the ointment will also be interrupted.

[0042] like Figure 2 and Figure 3 As shown, preferably, the second tube 33 has a push groove 331 at one end facing the cylindrical chamber 3. A push plate 332 is slidably installed in the push groove 331. A second spring 333 is connected between the push plate 332 and the bottom of the push groove 331 so that the push plate 332 can press against the edge of the conveyor plate 31. When the conveyor plate 31 rotates, the push plate 332 presses against the surface of the conveyor plate 31 and the transfer groove 311 and scrapes off the ointment attached to the inner wall of the transfer groove 311, so that the ointment is fully scraped off the transfer groove 311 passing through the top of the second tube 33, thereby improving the transfer efficiency.

[0043] Furthermore, the rounded transition between the edges of the transfer groove 311 and the conveyor plate 31 helps to improve the smoothness of the contact between the push plate 332 and the transfer groove 311 and the conveyor plate 31, so that the attached ointment is scraped off more thoroughly.

[0044] like Figure 2 and Figure 4 As shown, in one embodiment, the drive mechanism 4 includes a drive shaft 41, a transmission shaft 42, and a transmission belt 43. The drive shaft 41 is rotatably connected to the bottom of the inner cavity of the box body 1. A drive wheel 411 protruding from the bottom of the box body 1 is provided on the drive shaft 41. The transmission shaft 42 is coaxially connected to the conveyor plate 31, and its end passes through the side wall of the cylindrical compartment 3 and is connected to the drive shaft 41 via the transmission belt 43. In actual use, the bottom of the box body 1 is moved against the patient's symptom area, which drives the drive wheel 411 to roll, thereby driving the conveyor plate 31 to rotate through the transmission belt 43. The ointment is continuously delivered while the ointment is applied, improving the efficiency of the ointment application. When the box body 1 stops moving, the rolling of the drive wheel 411 will also stop, thereby stopping the delivery of the ointment, which is convenient for the user to operate.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, a balancing component is also included, which includes a plate 23, a sliding seat 24, and a connecting rod 25. The two ends of the control rod 2 pass through both sides of the buffer chamber 12. One end of each of the two connecting rods 25 is fixedly connected to the two protruding ends of the control rod 2, and the other end extends upward and is provided with a movable groove 251. The sliding seat 24 is installed on the top of the inner cavity of the box body 1. The plate 23 is slidably installed on the sliding seat 24, and one end of the plate 23 slides through one side of the first tube 32. The other end is provided with connectors 231 that are slidably connected to the corresponding movable grooves 251 on both sides. In practical use, when the buffer plate 21 is pushed by the continuously flowing ointment and rotates towards the bottom of the buffer chamber 12, the control rod 2 will drive the connecting rod 25 to rotate synchronously, and drive the insert plate 23 to slide along the sliding seat 24, so that the insert plate 23 is pushed into the first tube 32 synchronously, so that the passage of the first tube 32 is gradually blocked by the insert plate 23, thereby reducing the amount of ointment falling into the cylindrical chamber 3, preventing too much ointment from entering the buffer chamber 12 and forming high pressure, which would cause the ointment to spray out excessively from the flat opening 121; when the buffer plate 21 is pushed upward by the first spring 22, the control rod 2 will drive the connecting rod 25 to drive the insert plate 23 to gradually move away from the first tube 32, so that the passage of the first tube 32 is expanded again, thereby increasing the amount of ointment falling into the cylindrical chamber 3, so as to ensure that the amount of ointment in the buffer chamber 12 is sufficient.

[0046] By using a balancing component, the ointment delivery is reduced when the amount of ointment in the buffer chamber 12 increases, and the ointment delivery is increased when the amount of ointment in the buffer chamber 12 decreases. This helps to maintain a dynamic balance of the amount of ointment in the buffer chamber 12, achieving adaptive adjustment. This keeps the downward pressure of the ointment flowing into the buffer chamber 12 and the upward pressure of the first spring 22 on the buffer plate 21 within a controllable range, ensuring stable pressure in the buffer chamber 12, and thus ensuring that the ointment can be smoothly discharged from the flat opening 121.

[0047] Furthermore, a locking assembly is included, comprising a toothed ring 26 and a locking rod 27. The toothed ring 26 is located on the outside of the drive shaft 41. One end of the locking rod 27 is fixedly connected to one end of the control rod 2, and the other end is provided with a locking pawl 271. When the buffer plate 21 rotates to the bottom of the buffer chamber 12, that is, when the amount of ointment in the buffer chamber 12 reaches the storage threshold, the control rod 2 will drive the locking rod 27 to rotate so that the locking pawl 271 presses against the toothed ring 26. The locking pawl 271 is locked between the teeth of the toothed ring 26, thereby locking the rotation of the drive wheel 411, stopping the rotation of the conveyor plate 31, and thus directly stopping the ointment delivery until the amount of ointment in the buffer chamber 12 is reduced.

[0048] like Figure 2 As shown, preferably, the top of the buffer chamber 12 is provided with a diversion chamber 13, and the top of the buffer chamber 12 has multiple diversion ports 122 communicating with the diversion chamber 13. The top of the diversion chamber 13 is connected to the bottom end of the second tube 33, which is beneficial to allow the ointment to flow evenly from the top of the buffer chamber 12 and balance the pressure. The above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it; although the present invention 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; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
