Description

Technical Field

[0001] This invention relates to the field of auxiliary ointment application, and more specifically to an auxiliary ointment application device for rheumatic and immunological diseases. Background Technology

[0002] Rheumatic and immunological diseases are a class of diseases in internal medicine that affect multiple systems and organs, including rheumatoid arthritis. Their etiology is complex, often related to factors such as genetics, infection, and immune abnormalities, and can cause damage to the blood system and other organs. Among the many rheumatic and immunological diseases, rheumatoid arthritis (RA) is one of the most common clinical types. In the early stages, it often manifests as joint pain, swelling, and stiffness, with "morning stiffness" being a typical characteristic. This means that patients experience joint stiffness and limited mobility upon waking, usually lasting for more than one hour, which gradually eases after activity. As the disease progresses, joint damage gradually worsens, potentially leading to joint deformities, functional impairment, and even disability, severely affecting the patient's daily activities.

[0003] Currently, the core objectives of treating rheumatic and immunological diseases are to control inflammation, relieve symptoms, protect joint function, and slow disease progression. Treatment methods mainly include oral medication, topical medication, and surgery. Among these, the comprehensive treatment plan combining oral and topical medications is the most widely used in clinical practice. Topical medications, as an important means of local treatment, can act directly on the skin surface of the affected joint, quickly relieving local pain, swelling, and other symptoms. They also have low systemic absorption and mild adverse reactions, making them the treatment method used by most patients.

[0004] Topical medications involve two steps: squeezing out the ointment and applying it. For patients with rheumatic and immunological diseases affecting the finger joints, such as rheumatoid arthritis, there are significant challenges in using them. Patients often experience finger joint deformities and decreased grip strength, making it difficult for them to independently squeeze and apply the ointment. Traditional ointment tubes require forceful pinching to squeeze out the ointment, which is difficult and can easily cause joint pain for patients with limited finger joint mobility and insufficient grip strength. There are squeeze clips available on the market to assist with squeezing, such as ointment squeezers, which include a squeezing clip. When the squeezing clip is pushed, the ointment can be squeezed out from the dispensing port. The advantage is that it not only helps patients easily squeeze out the ointment but also maximizes the amount of ointment squeezed out of the tube, reducing waste. However, in practical use, it has been found that the small size of the clip makes it easy to lose. Furthermore, most patients use traditional application methods (such as applying by hand or with a cotton swab), which are difficult to apply evenly to the affected area, leading to ointment waste and insufficient contact with the lesion, thus affecting the treatment effect. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an auxiliary medication application device for rheumatic and immunological diseases, which integrates auxiliary squeezing and auxiliary application into one unit. It is used to assist patients with rheumatic and immunological diseases in squeezing and applying medication, compensating for the inconvenience caused by finger joint deformities and decreased grip strength, and providing convenience for patients in applying medication.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An auxiliary application device for rheumatic and immunological diseases includes an ointment and a hollow container. A base is fixedly connected to the container, and a connection port is opened on the base. The dispensing end of the ointment is fixedly connected to the connection port. The sealing end of the ointment is detachably connected to a squeezing component for squeezing the ointment. A drug storage cavity is provided at the bottom of the container. An arc-shaped contact surface is fixedly connected to the bottom of the container. Several through holes are provided on the contact surface. All through holes communicate with the drug storage cavity. A ball bearing is fixedly connected to the bottom of each through hole.

[0007] The technical principles of the above solution are as follows: When a patient needs to use medication, they first press the squeeze component. The ointment inside the container is squeezed out of the tube and enters the storage chamber. Under the action of gravity, the ointment enters the through hole. The patient places the contact surface on the knee or other areas of rheumatic pain, holds the container with their hand, and rolls it back and forth. The rolling ball causes the ointment in the through hole to roll out and come into contact with the patient's skin, achieving the effect of assisting in the application of medication.

[0008] The above approach has the following beneficial effects: 1. In this solution, the base fixes the ointment to prevent it from shifting or tilting during the squeezing process, thus ensuring stable dispensing.

[0009] 2. In this method, the rollerball assists in the even application of the ointment to the patient's joints, improving the uniformity and comfort of the application and reducing the problem of uneven application when using manual methods.

[0010] 3. This design features an arc-shaped contact surface, which better conforms to the patient's joint curvature, improving the compatibility between the device and the affected area, enhancing the user experience and the effectiveness of medication application.

[0011] Furthermore, the extrusion assembly includes a clamping plate with a clamping opening, and a push rod assembly is detachably connected to the side wall of the clamping plate.

[0012] Beneficial effects: The clamp holds and fixes the sealed end of the ointment, and works with the push rod assembly to achieve synchronous pressing, making the squeezing action more stable and the force more even, avoiding the ointment from tilting or wrinkling during squeezing.

[0013] Furthermore, the push rod assembly includes a first push rod and a second push rod, and a first slide groove and a second slide groove are respectively provided on both sides of the receiving body. The first push rod and the second push rod pass through the receiving body and are slidably connected with the first slide groove and the second slide groove respectively.

[0014] Beneficial effects: The first and second chutes guide and limit the movement of the first and second push rods, ensuring a straight and stable extrusion path, reducing the risk of jamming, and improving the smoothness of operation and the overall reliability of the device. Furthermore, both the first push rod and the bottom of the second push rod are detachably connected to a squeezing rod located within the housing. The bottom of each squeezing rod is equipped with a cleaning component for assisting in cleaning the contact surface through the vertical movement of the squeezing rod.

[0015] Beneficial effects: It integrates squeezing and cleaning, and can clean the contact surface, ball bearings and through holes after the medicine is applied, so as to avoid the ointment residue drying and clogging.

[0016] Furthermore, each cleaning component includes a cleaning airbag, which is fixedly connected to the top of the base. Each cleaning airbag contains a volatile cleaning liquid, and the liquid outlet of the cleaning airbag is fixedly connected to the top of the contact surface.

[0017] Beneficial effects: The cleaning solution can be released by pressing to clean the contact surface. The cleaning solution evaporates quickly without leaving any residue, which ensures the cleaning effect and avoids moisture contamination of the skin or ointment.

[0018] Furthermore, the connector is provided with an internal thread corresponding to the ointment dispensing end.

[0019] Beneficial effects: Enables a detachable threaded connection between the ointment and the device, ensuring a tight connection without leakage, convenient disassembly and replacement, and compatibility with commonly used ointments.

[0020] Furthermore, wedges are provided between the rollers to help the ointment spread in all directions.

[0021] Beneficial effects: The wedge can guide and divert the outflowing ointment, allowing the ointment to spread more evenly in all directions as the ball rolls, improving the coverage and uniformity of the ointment application.

[0022] Furthermore, the contact surface is provided with an elastic layer.

[0023] Beneficial effects: The elastic layer can cushion the hard contact pressure between the device and the skin, improve the comfort of the fit, and reduce the pressure and irritation on the joints of rheumatism patients.

[0024] Furthermore, the container is symmetrically connected with gas channels, each of which is connected to a trachea. The tracheas are distributed in a mesh pattern within the contact surface, and each trachea is connected to a through hole.

[0025] Beneficial effects: During the application of the medicine, it can balance the internal air pressure of the container, prevent the ointment from being difficult to flow out smoothly due to negative pressure, ensure continuous and stable dispensing, and improve the smoothness of the application.

[0026] Furthermore, an arc-shaped rubber cap is detachably attached to the top of the container.

[0027] Beneficial effects: The arc-shaped rubber cap can form a closed gas-containing cavity. When the rubber cap is pressed, the residual ointment in the through hole can be fully squeezed out, reducing ointment waste and preventing ointment residue from drying and causing blockage.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The following detailed description illustrates the specific implementation method: Example 1:

[0034] As attached Figure 1 and Figure 2 As shown: An auxiliary medication application device for rheumatic and immunological diseases includes an ointment and a hollow container 1. A base 2 is welded to the inner wall of the container 1, and a connection port 3 is opened on the base 2. The connection port 3 has an internal thread 13 corresponding to the dispensing end of the ointment, and the dispensing end of the ointment is fixed to the connection port 3 by the thread. The sealing end of the ointment is detachably connected to a squeezing component for squeezing the ointment. A drug storage cavity 19 is provided at the bottom of the container 1, and an arc-shaped contact surface 4 is welded to the bottom of the container 1. An elastic layer 15 is provided at the bottom of the contact surface 4. Figure 4 As shown, the contact surface 4 is provided with several through holes 5, all of which are connected to the medicine storage cavity 19, and several balls 6 are fixed at the bottom of each through hole 5.

[0035] The extrusion assembly includes a clamping piece 7 with a clamping opening 8 (the width of the clamping opening 8 is the same as the width of the sealing end of the ointment). A push rod assembly is detachably connected to the side wall of the clamping piece 7. The push rod assembly includes a first push rod 901 and a second push rod 902 (a slot is provided on the side wall of the clamping piece 7, and a buckle corresponding to the slot is provided at one end of the first push rod 901 and the second push rod 902). A first sliding groove 101 and a second sliding groove 102 are respectively provided on both sides of the receiving body 1. The first push rod 901 and the second push rod 902 pass through the receiving body 1 and are slidably connected to the first sliding groove 101 and the second sliding groove 102 respectively.

[0036] The specific implementation process is as follows: Before the patient applies the medicine, the first push rod 901 and the second push rod 902 are pushed downwards. The first push rod 901 and the second push rod 902 drive the clamp 7 to move downwards. The clamp 8 squeezes the ointment tube, causing the ointment to be squeezed out. Then the ointment enters the medicine storage chamber 19 and flows into the through hole 5 under the action of gravity, completing the squeezing action before applying the medicine. After squeezing is completed, in order to prevent accidental contact and continued squeezing, the first push rod 901 and the second push rod 902 can be pushed upwards.

[0037] The patient then aligns the contact surface 4 with the affected joint and makes contact. The contact surface 4 has an elastic layer 15 that can effectively protect the patient's affected area and reduce irritation. The patient then pushes the container 1 back and forth, and the roller ball 6 rolls back and forth during the pushing process. The ointment follows the roller ball 6 and is evenly applied to the affected area. Because the contact surface 4 adopts an arc-shaped structure design, it can better fit the curved contour of the human joint, so that the roller ball 6 can make more full contact with the skin of the affected area. This not only improves the uniformity of the ointment application, but also enhances the patient's comfort during use, effectively solving the problems of uneven manual application and inconvenience in fitting the joint area.

[0038] When the ointment in the container 1 needs to be replaced, push the clip 7 horizontally. The buckles on the first push rod 901 and the second push rod 902 slide out along the slot on the clip 7. Remove the clip 7, rotate the ointment in the opposite direction to remove the used ointment from the base 2, and then rotate the new ointment in the forward direction to fix it on the base 2. Finally, clamp one end of the ointment with the clip 8 of the clip 7. Then, the slot on the clip 7 locks with the buckles on the first push rod 901 and the second push rod 902 respectively. Finally, the first push rod 901 and the second push rod 902 are reset.

[0039] Rheumatism patients often experience symptoms such as finger joint deformities and decreased grip strength, making it difficult for them to squeeze out ointments. This solution uses a clamp 7, a first push rod 901, and a second push rod 902 in conjunction to transform the action of pushing the first push rod 901 and the second push rod 902 into a squeezing action on the ointment tube, allowing patients to more easily complete the application of the ointment and achieving the purpose of assisting patients in applying the ointment. In addition, considering the general shape of ointments on the market, the ointment is generally a long and thin cylinder, with the tube gradually narrowing from the dispensing end to the sealing end. The width of the clamp 8 is the same as the width of the sealing end of the ointment, allowing the clamp 7 to form a tight grip on the ointment tube. The ointment is subjected to more even and sufficient force during the squeezing process, and almost all the ointment in the tube can be squeezed out, effectively reducing the ointment residue in the tube, significantly improving the utilization rate of the ointment, and avoiding resource waste. Meanwhile, the overall structure of this solution is simple and the installation process is easy to understand. Patients can complete the installation themselves without the help of others. The device is reusable, taking into account both practicality and economy, and is more in line with the daily use needs of rheumatism patients.

[0040] Example 2:

[0041] As attached Figure 2 and Figure 5 As shown, the difference from Example 1 is that, in order to spread the ointment more evenly in all directions during the rolling of the roller ball 6, avoiding local accumulation or uneven application, as... Figure 6As shown, each of the 6 ball bearings is equipped with a wedge 14 to assist in the diffusion of the ointment in all directions. Meanwhile, considering that the ointment may become clogged in the through-hole 5 due to its viscous texture or long-term residue during long-term storage or frequent use, thus affecting the normal flow of the ointment, the container 1 is connected to a gas channel 16, such as... Figure 5 As shown, each gas channel 16 is connected to an air tube 18, which is distributed in a mesh pattern within the contact surface 4. The air tubes 18 are connected to each through hole 5, and an arc-shaped rubber cap 17 is detachably connected to the top of the container 1. The rubber cap 17 can help to completely squeeze out the ointment.

[0042] The specific implementation process is as follows: The arc-shaped rubber cap 17 not only serves as a seal, but also can hold a large amount of gas. When the patient presses the rubber cap 17, the rubber cap 17 deforms, causing the gas inside the rubber cap 17 to move towards the bottom of the container 1 and enter the gas channel 16. Then, it enters the interior of each through hole 5 through the air tube 18, forming a uniform air pressure. This continuously squeezes the ointment remaining on the inner wall of the through hole 5, fully squeezing the attached ointment to the application site, effectively reducing ointment waste, and preventing residual ointment from accumulating and drying out and clogging the through hole 5, thus ensuring the normal use of the device in the future.

[0043] After the ointment is completely squeezed out, the through hole 5 allows air to circulate. Under the influence of the air pressure difference, the outside air flows back into the rubber cap 17 through the through hole 5, air tube 18, and gas channel 16, pushing the deformed rubber cap 17 to gradually return to its original shape, completing the reset process. Throughout the process, the sealing performance and elastic deformation characteristics of the arc-shaped rubber cap 17 are utilized to achieve the compression, pressure transmission, and reset functions of the piston. The structure is simple and highly practical.

[0044] In terms of application, the arc-shaped structure of the contact surface 4 results in less ointment in the through hole 5 far from the center, while the amount of ointment in the through hole 5 in the middle is large. This may cause accumulation or even blockage during the application process. When a large amount of ointment is on the surface of the ball 6, the ointment is transferred to the next ball 6 along the inclined surface of the wedge block 14, which further spreads the ointment along the wedge block 14 to the surrounding areas, effectively avoiding local accumulation or uneven application.

[0045] This solution uses the rubber cap 17 and the air tube 18 to achieve air pressure assistance to squeeze out the through hole 5, forming a uniform air pressure to squeeze the residual ointment on the inner wall of the through hole 5, achieving full extrusion, reducing waste and preventing the through hole 5 from becoming blocked; and the design of the wedge block 14 guides the ointment to spread it evenly in all directions, further preventing the ointment from accumulating locally, solving the problem of blockage caused by ointment residue, optimizing the flow path of the ointment on the application surface, so that patients can apply the medicine more effortlessly and evenly during the operation.

[0046] Example 3:

[0047] As attached Figure 2As shown, the difference from Embodiment 2 is that the bottoms of both the first push rod 901 and the second push rod 902 are detachably connected to a squeezing rod 11 located within the housing 1 (the squeezing rod 11 adopts a telescopic structure, composed of multiple sections of squeezing rods, each section of squeezing rods is slidably connected, and each section of squeezing rods is provided with a locking bead, which can increase the resistance of a single section of squeezing rods and prevent insufficient pressure). The bottom of each squeezing rod 11 is provided with a cleaning component for assisting in cleaning the contact surface 4 through the vertical movement of the squeezing rod 11. Each cleaning component includes a cleaning airbag 12, which is fixed to the top of the base 2. The cleaning airbag 12 contains a volatile cleaning liquid, and the liquid outlet end of the cleaning airbag 12 is welded to the top of the contact surface 4.

[0048] The specific implementation process is as follows: When the patient presses the first push rod 901 and the second push rod 902, the vertical movement of the squeezing rod 11 causes the cleaning airbag 12 at the bottom of the squeezing rod 11 to be squeezed against the base 2 and deformed (when the squeezing rod 11 is squeezed downwards, the pressure rod contracts under force, and the locking ball increases the resistance between the pressure rods, preventing the cleaning airbag 12 from failing to deform due to insufficient pressure). After the cleaning airbag 12 is squeezed, the volatile cleaning fluid inside it is slowly released from the liquid outlet of the cleaning airbag 12 under pressure and evenly distributed on the surface of the contact surface 4. The cleaning fluid, with its good volatility and permeability, can effectively clean key structural parts such as the ball bearing 6, the through hole 5, and the wedge block 14.

[0049] The cleaning solution uses a volatile formula that evaporates quickly after use, eliminating the need for additional wiping or rinsing. The contact surface 4 will dry out completely, making it ready for the next use. After applying the medication, patients can easily clean key areas such as the roller ball 6, through-hole 5, and wedge 14 without the need for external tools. The operation is simple and labor-saving, fully considering the practical needs of rheumatism patients with limited hand function.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
