Description

Technical Field

[0001] This invention relates to the field of biomedical technology, and in particular to a device for uniformly applying drugs. Background Technology

[0002] In the medical field, topical application of medication is a common treatment method, used to evenly apply ointments or drugs to the affected area to achieve a therapeutic effect. Traditional methods of topical application usually involve directly applying the ointment using cotton swabs, brushes, or other tools. While this method is simple, it is prone to introducing bacteria or contaminating the ointment in practical applications, especially when multiple people use it or when it is repeatedly applied, increasing the risk of cross-infection. Secondly, traditional methods can easily leave ointment residue during the application process, which not only wastes the medication but also affects the distribution of the medication on the affected area and the therapeutic effect. In addition, the need for repeated application and wiping makes the operation cumbersome and inconvenient for patients or their families with limited mobility, thus affecting the efficiency of treatment. Summary of the Invention

[0003] To address the problems mentioned in the background section, the present invention provides a drug uniform application device.

[0004] The technical solution of the present invention is as follows: a drug uniform application device, comprising two protective covers that are in contact with each other, a bottom shell detachably connected to one side of the two protective covers, a protective shell detachably connected to the other side of the two protective covers, ointment placed inside the two protective covers, two fixing frames fixedly connected inside the protective shell, two guide rollers rotatably connected between the two fixing frames, a contact wheel fixedly connected to the guide rollers away from the protective shell, and a drug delivery belt wound around the two guide rollers.

[0005] As a further preferred embodiment, a fixing ring is fixedly connected between the two fixing frames. The fixing ring is threadedly connected to the ointment. The fixing ring is fixedly connected to and connected to a guide tube. The guide tube is used to guide the medication in the ointment to the delivery belt.

[0006] As a further preferred embodiment, the fixing ring is fixed with a number of spikes.

[0007] As a further preferred embodiment, two extrusion frames are rotatably connected between the two fixed frames, and fixed plates are fixed to the opposing sides of the two extrusion frames. The side of the fixed plate away from the adjacent extrusion frame is a wavy side, and the wavy sides of the two fixed plates match each other. The fixed plates are used to extrude the guide tube.

[0008] As a further preferred embodiment, the protective shell is provided with two sets of symmetrically distributed guide grooves, each set of guide grooves consisting of two symmetrically distributed guide grooves. The guide grooves in the same set are slidably connected to a pressing rod, which is used to press the adjacent pressing frame. The two pressing rods are slidably connected to two connecting rings, and both connecting rings are located outside the protective shell. Two fixing frames are fixed inside the protective shell, and a first tension spring is provided between the fixing frame and the adjacent pressing frame.

[0009] As a further preferred embodiment, the guide groove is L-shaped, and the distance between two adjacent guide grooves in different groups of guide grooves first decreases and then increases.

[0010] As a further preferred embodiment, a sliding frame is provided between the two protective covers for limiting and sliding connection. The sliding frame is slidably connected to a pressing member that slides along the adjacent protective cover. The sliding frame is rotatably connected to a support frame. The support frame is slidably connected to two extrusion plates, and the two extrusion plates are used together to extrude the ointment.

[0011] As a further preferred embodiment, the support frame is slidably connected to a sliding plate, and a second tension spring is provided between the sliding plate and the support frame. The sliding plate slides along the two extrusion plates, and the sliding plate is fixedly connected to at least two U-shaped frames, which are used to extrude the two extrusion plates.

[0012] As a further preferred embodiment, a first rack is fixedly connected to the protective cover near the pressing member. An elastic lever is detachably connected to the side of the first rack away from the pressing member. A locking tooth is provided on the side of the pressing member near the first rack. The elastic lever is used to squeeze the locking tooth of the pressing member. When the locking tooth contacts the first rack, it restricts the position of the pressing member. A spring is provided between the pressing member and the adjacent protective shell.

[0013] As a further preferred embodiment, the protective shell, located away from the pressing member, is fixedly connected to a second rack, and the bearing frame is fixedly connected to a gear that meshes with the second rack.

[0014] The present invention has the following advantages: The present invention applies the medicine in the ointment to the patient's lesion by rotating the medicine delivery belt along two guide rollers, in order to simulate the working mode of the correction belt. It designs a device that can transfer and apply medicine evenly and hygienically. This method can not only solve the problems of easy introduction of bacteria, increased risk of cross-infection, ointment residue and waste, and cumbersome operation in the traditional method, but also improve the patient's treatment experience.

[0015] After the medication is applied, the adjacent extrusion rods are locked by the guide groove to isolate the medication inside the ointment from the outside environment.

[0016] To avoid the formation of drug residue on the inner wall of the ointment after long-term use or repeated squeezing, which leads to low utilization and unnecessary waste, this invention addresses this problem by using a rotating support frame to wind the ointment during movement. This changes the way force is applied to the ointment, reduces residue, improves utilization, and ensures uniform application of the drug. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setup" and "connection" 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 the present invention based on the specific circumstances.

[0032] To address the risks of ointment contamination, residue and waste, and cumbersome procedures associated with traditional drug application methods in practical applications, which can affect treatment efficacy and patient compliance, the following explanation is provided.

[0033] Example 1

[0034] A drug uniform application device, such as Figures 1-6 As shown, it includes two protective covers 1 that are in contact with each other. A bottom shell 2 is detachably connected to one side of the two protective covers 1. A protective shell 3 is detachably connected to the other side of the two protective covers 1. Ointment 4 is placed inside the two protective covers 1. Two fixing brackets 5 are fixed inside the protective shell 3. Two guide rollers 6 are rotatably connected between the two fixing brackets 5. A contact wheel 601 is fixed to the guide roller 6 away from the protective shell 3. A medicine delivery belt 7 is wound around the two guide rollers 6.

[0035] In the above scheme, the protective shell 3 can be a transparent hard shell. In this embodiment, the two protective covers 1 can be transparent soft shells. The outer side of the drug delivery belt 7 is a smooth part, which can be a polyester film to prevent drug accumulation. The inner side of the drug delivery belt 7 is a rough part to increase the friction between it and the two guide rollers 6. The diameter of the upper guide roller 6 is smaller than the diameter of the lower guide roller 6. The distance between the outer side of the contact wheel 601 and the axis of the upper guide roller 6 is greater than the distance between the upper side of the drug delivery belt 7 and the axis of the upper guide roller 6. By simulating the working mode of the correction belt, the drug is applied to the patient's lesion to solve the problems of easy introduction of bacteria, infection risk, ointment residue and waste, and cumbersome operation in the traditional method.

[0036] like Figures 6-8 As shown, a fixing ring 8 is fixed between the two fixing frames 5. The fixing ring 8 is threadedly connected to the ointment 4. The fixing ring 8 is fixed and connected to a guide tube 9. The guide tube 9 is used to guide the medicine in the ointment 4 through the fixing ring 8 to the delivery belt 7. Several spikes 801 are fixed inside the fixing ring 8.

[0037] In the above scheme, the guide tube 9 is made of deformable material. The guide tube 9 is used to transport the medicine in the ointment 4 to the outside of the delivery belt 7. The spike 801 is used to pierce the seal of the ointment 4 so that the ointment 4 can guide the medicine into the guide tube 9.

[0038] like Figure 6 and Figure 7 As shown, two extrusion frames 10 are rotatably connected between the two fixed frames 5. Fixed plates 11 are fixed to the opposing sides of the two extrusion frames 10. The side of the fixed plate 11 away from the adjacent extrusion frame 10 is a wavy side. The wavy sides on the two fixed plates 11 match each other. The fixed plates 11 are used to extrude the guide tube 9.

[0039] In the above scheme, the fixing plate 11 is made of a deformable material. When the two fixing plates 11 squeeze the guide tube 9, they achieve the effect of isolating the medicine in the ointment 4 from contact with the outside world.

[0040] like Figures 3-7 As shown, the protective shell 3 is provided with two sets of symmetrically distributed guide grooves 12. Each set contains two symmetrically distributed guide grooves 12. The two guide grooves 12 in the same set are slidably connected to a pressing rod 13. The pressing rod 13 is used to press the adjacent pressing frame 10. The two pressing rods 13 are slidably connected to two connecting rings 14, and both connecting rings 14 are located outside the protective shell 3. Two fixing frames 15 are fixed inside the protective shell 3. A first tension spring is provided between the fixing frame 15 and the adjacent pressing frame 10. The guide grooves 12 are L-shaped. The distance between two adjacent guide grooves 12 in different sets of guide grooves 12 first decreases and then increases.

[0041] In the above scheme, when the connecting ring 14 moves upward, the two extrusion rods 13 slide towards each other under the guidance of the corresponding guide groove 12. When the extrusion rod 13 is located on the upper side of the corresponding guide groove 12, the extrusion rod 13 is locked to prevent the extrusion rod 13 from being pulled by the first tension spring adjacent to the extrusion frame 10.

[0042] Before applying the medication using this device, the user first removes the bottom shell 2 and the two protective covers 1 from the bottom of the protective shell 3, and then screws the ointment 4 into the retaining ring 8. As the retaining ring 8 is screwed in, the spike 801 pierces the seal on the top of the ointment 4, allowing the ointment 4 to guide the medication into the guide tube 9. After the ointment 4 is installed, the user reinstalls the bottom shell 2 and the two protective covers 1 onto the bottom of the protective shell 3.

[0043] When the device is needed to apply medication, the user squeezes the protective cover 1, which deforms and squeezes the ointment 4, allowing the medication in the ointment 4 to enter the guide tube 9. The guide tube 9 then guides the medication to the delivery belt 7. At the same time, the user brings the delivery belt 7 and the contact wheel 601 into contact with the patient's wound. The user then moves the device, during which the contact wheel 601 rotates along the patient's skin, thereby driving the delivery belt 7 to rotate via the guide roller 6. The delivery belt 7 rotates along the two guide rollers 6 and applies the medication to the patient's wound. When the delivery belt 7 applies the medication to the patient's wound, it squeezes the medication to spread it evenly on the wound, achieving a uniform application effect.

[0044] After the application of the medicine is about to be completed, the user stops squeezing the protective cover 1, and the ointment 4 is no longer squeezed. Then the user pushes the two connecting rings 14 toward the side closer to the patient's injury, so that the two connecting rings 14 drive the two squeezing rods 13 to slide along the corresponding guide grooves 12. During the sliding process, the two squeezing rods 13 approach each other and squeeze the corresponding squeezing frame 10. The squeezing frame 10 drives the corresponding fixing plate 11 to swing toward the guide tube 9 and squeeze the guide tube 9 (during the swing of the squeezing frame 10, the adjacent first tension spring is stretched, so that the first tension spring is in a stretched state).

[0045] After the two fixed plates 11 squeeze the guide tube 9 into a flat shape, the remaining medicine in the guide tube 9 is transferred to the delivery belt 7, which then applies the medicine to the patient's wound. This completes the application to the patient's wound. Subsequently, the user moves the two squeezing rods 13 to the side of the corresponding guide groove 12 closest to the guide roller 6. The guide groove 12 locks the adjacent squeezing rods 13, preventing the squeezing rods 13 from being pulled by the first tension spring adjacent to the squeezing frame 10. Through the above actions, the medicine in the ointment 4 is isolated from contact with the outside world.

[0046] When the device is needed again to apply the medication to the patient's wound, the user presses the two connecting rings 14 downwards, causing the two connecting rings 14 to drive the two extrusion rods 13 to slide along the corresponding guide grooves 12 respectively. This prevents the two extrusion rods 13 from contacting the side of the corresponding guide groove 12 closest to the guide roller 6. Then, under the action of the adjacent first tension spring of the extrusion frame 10, the extrusion frame 10 is driven to open outwards, and the two extrusion frames 10 then stop extruding the guide tube 9. The subsequent medication application can be repeated as described above.

[0047] Example 2

[0048] Existing ointments typically use a squeezing method to expel the medication from a tube. This method has the following problems in practical use: after long-term use or repeated squeezing, medication residue easily forms on the inner wall of the tube, resulting in low utilization rate and unnecessary waste. The present invention solves the above problems through the following description:

[0049] Based on Example 1, such as Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, a sliding frame 16 is slidably connected between the two protective covers 1. The sliding frame 16 is slidably connected to a pressing member 17 that slides along the adjacent protective cover 1. The sliding frame 16 is rotatably connected to a bearing frame 18. The bearing frame 18 is slidably connected to two extrusion plates 19. The two extrusion plates 19 are used together to extrude the ointment 4.

[0050] In the above scheme, the ointment 4 is squeezed and fixed when the two extrusion plates 19 are close to each other. In this embodiment, the two protective covers 1 are transparent hard shells.

[0051] like Figures 10-12 As shown, a sliding plate 20 is slidably connected to the support frame 18. A second tension spring is provided between the sliding plate 20 and the support frame 18. The sliding plate 20 slides along two extrusion plates 19. At least two U-shaped frames 21 are fixedly connected to the sliding plate 20. The U-shaped frames 21 are used to extrude the two extrusion plates 19.

[0052] In the above scheme, two symmetrically distributed inclined grooves are provided on the upper side of the U-shaped frame 21, and the distance between the two inclined grooves gradually decreases from bottom to top. The part of the extrusion plate 19 that contacts the inclined groove of the adjacent U-shaped frame 21 is cylindrical. Figure 10 The state in which the two extrusion plates 19 have squeezed and fixed the ointment 4, and the second tension spring between the sliding plate 20 and the bearing frame 18 is in a stretched state.

[0053] like Figures 9-13As shown, a first rack frame 22 is fixedly connected to the protective cover 1 near the pressing member 17. An elastic lever 23 is detachably connected to the side of the first rack frame 22 away from the pressing member 17. A locking tooth is provided on the side of the pressing member 17 near the first rack frame 22. The elastic lever 23 is used to squeeze the locking tooth of the pressing member 17. When the locking tooth contacts the first rack frame 22, it restricts the position of the pressing member 17. A spring is provided between the pressing member 17 and the adjacent protective shell 3. A second rack frame 24 is fixedly connected to the protective shell 3 away from the pressing member 17. A gear 25 that meshes with the second rack frame 24 is fixedly connected to the support frame 18.

[0054] In the above scheme, when the locking teeth of the pressing member 17 contact the first rack frame 22, the pressing member 17 is locked. The spring between the pressing member 17 and the adjacent protective shell 3 is a non-linear spring. During the upward movement of the pressing member 17, the adjacent spring is squeezed. During the compression process, the spring gradually increases the resistance to achieve the effect of reminding the user.

[0055] When the device is needed to apply the medicine to the patient's affected area, the user first repeats the fixing method of the ointment 4 in Example 1, and then inserts the protective shell 3 and the ointment 4 into the protective cover 1. As the ointment 4 gradually penetrates, the ointment 4 contacts and squeezes the sliding plate 20 (the sliding plate 20 squeezes the second tension spring during its movement), causing the sliding plate 20 to drive the U-shaped frame 21 to move downward. During the movement of the U-shaped frame 21, the two inclined grooves on its upper side squeeze the two extrusion plates 19, so that the two extrusion plates 19 come close together and squeeze the lower side of the ointment 4.

[0056] After the protective shell 3 and protective cover 1 are assembled, the two extrusion plates 19 have fixed the lower side of the ointment 4. When the medicine in the ointment 4 needs to be applied to the patient's affected area, the user first presses the pressing member 17, causing the pressing member 17 to slide along the sliding frame 16 towards the center. During the sliding process of the pressing member 17, the locking teeth move synchronously (the locking teeth squeeze the elastic paddle 23 during the movement), so that the locking teeth no longer contact the first rack frame 22. Then, the user pushes the pressing member 17 towards the side closer to the protective shell 3 (the pressing member 17 squeezes the spring during the movement). The pressing member 17 drives the bearing frame 18 and its attachments through the sliding frame 16. As the components move synchronously, the carrier frame 18 drives the gear 25 to rotate and move upward along the second rack frame 24, causing the carrier frame 18 to rotate during its movement. During the rotation of the carrier frame 18, the ointment 4 is wound around its components to change the way force is applied to the ointment 4. By winding, the medicine in the ointment 4 is squeezed and enters the guide tube 9 to achieve the export of the medicine. When the medicine is no longer needed, the user can release the pressing piece 17. The elastic lever 23 rebounds and drives the pressing piece 17 to move in the opposite direction and reset. During the reset process of the pressing piece 17, the locking teeth re-engage into the first rack frame 22.

[0057] When the ointment 4 is used up, the user presses the pressing part 17, and then the pressing part 17 moves the sliding frame 16 and its parts back to their original position under the action of the spring, so that the ointment 4 changes from the rolled state to the unrolled state. Then the user removes the protective shell 3 and the ointment 4. After the ointment 4 leaves the protective cover 1, the sliding plate 20 moves in the opposite direction under the action of the second tension spring. During the movement of the sliding plate 20, the U-shaped frame 21 moves synchronously. The two inclined grooves on the U-shaped frame 21 squeeze the two extrusion plates 19, so that the two extrusion plates 19 move in opposite directions. The ointment 4 can be replaced and the above actions can be repeated.

[0058] Although this disclosure has been shown and described with reference to specific exemplary embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made to this disclosure without departing from the spirit and scope thereof.
