Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an auxiliary extrusion device for mupirocin ointment. Background Art

[0002] Mupirocin ointment is a topical antibiotic with strong antibacterial activity against Gram-positive cocci (such as Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes), and is also effective against methicillin-resistant Staphylococcus aureus (MRSA). Mupirocin ointment is commonly used to reduce skin inflammation, relieving symptoms such as redness, swelling, pain, and itching associated with boils. It effectively promotes the repair of damaged skin tissue and accelerates wound healing. It also promotes healing by stimulating keratinocyte proliferation and increasing growth factors. It is particularly suitable for areas of damaged or inflamed skin, reducing the risk of infection spread.

[0003] Mupirocin ointment is a paste-like medication typically packaged in a specialized aluminum tube. It must be squeezed out of the tube for use. If the boil is on the hand, squeezing the ointment out and applying it to the affected area with one hand is inconvenient. Furthermore, the boil may be red, swollen, or inflamed, so applying the ointment may cause discomfort, such as pain. Summary of the Invention

[0004] In order to improve the situation where patients have difficulty squeezing out the ointment and experience pain and other discomfort when applying the ointment, the present application provides an auxiliary extrusion device for mupirocin ointment.

An extrusion port is provided at the center of the smear head for extruding the ointment, and an auxiliary extrusion mechanism for extruding the ointment is provided in the fixed extrusion part.

[0010] Optionally, the rotary drive mechanism includes an air blowing pipe, and there are multiple air blowing pipes that are spaced apart around the inner wall of the rotating coating part.

The air outlet of the air blowing pipe is inclined downward toward the side wall of the air flow plate to blow the air flow plate through the airflow.

[0011] Optionally, the air vent plate is an arc-shaped plate with its opening facing the air outlet of the air pipe.

[0012] Optionally, the air blowing pipe further includes an air inlet and an internal air blowing channel, and the diameter of the air blowing channel gradually decreases along the direction from the air inlet to the air outlet of the air blowing pipe.

[0013] Optionally, the aeration plate and the coating head are fixed via a connecting rod so that the aeration plate and the coating head rotate synchronously.

[0014] Optionally, a sliding groove is provided at the end of the rotating application portion away from the fixed extrusion portion, and the massage balls are all slidably connected in the sliding groove, with a portion of the massage balls exposed outside the sliding groove to contact the patient's skin.

[0015] Optionally, the rotating coating part and the fixed extrusion part are detachably connected, and the rotating coating part and the fixed extrusion part are respectively provided with an air inlet groove and an air outlet groove at one end close to each other. When the rotating coating part and the fixed extrusion part are connected as one, the air inlet groove and the air outlet groove are merged into a complete air guide groove, and the air outlet groove is connected to multiple air guide pipes, and the air guide pipe is connected to the cold air generating module at one end away from the rotating coating part, and the air blowing pipe is connected to the internal space of the air inlet groove.

[0016] Optionally, cooling components are embedded in both the air inlet and outlet slots. The cooling components are annular and have multiple layers. The multiple layers of cooling components are spaced apart along the axis of the rotating coating portion, and a gap is left between adjacent cooling components for airflow to pass through. Each cooling component has a wavy appearance with ups and downs, and the cooling component is made of phase-change heat-absorbing material.

[0017] Optionally, the auxiliary extrusion mechanism includes two parallel extrusion rollers, the axes of the extrusion rollers are perpendicular to the axis of the fixed extrusion part, and a positioning block is provided inside the fixed extrusion part near one end of the rotating application part.

[0019] In summary, this application has at least one of the following beneficial effects:

[0020] 1. By arranging a plurality of massage balls that can rotate in a circle at the end of the rotating application part, the massage balls protrude from the rotating application part. Therefore, when applying the ointment to the affected area, the massage balls are in direct contact with the patient's skin. When the ointment needs to be applied to the affected area, the cold air generating module provides a cold air flow to the air blowing pipe through the air guide pipe and the air guide groove. The air flow is gradually accelerated when it is blown out from the air outlet of the air blowing pipe with a gradually decreasing diameter. At this time, the air flow has been sufficiently accelerated when it is blown out from the air outlet of the air blowing pipe. At this time, the air flow speed is relatively fast, and the air flow blows directly to the arc-shaped scoop plate. The scoop plate starts to rotate in the rotating application part under the impact of the high-speed air flow. The rotating scoop plate drives the corresponding massage balls to rotate synchronously. All the rotating massage balls rotate around the boil affected area. At this time, the rotating massage balls can massage a circle of skin around the affected area, thereby alleviating the pain caused by the patient when applying the ointment and improving the patient's comfort.

[0021] 2. Since the cold air generating module provides a relatively low-temperature cold airflow, and the massage balls can be made of metal materials with good thermal conductivity, the cold airflow can cool the surface of the massage balls while driving the massage balls to rotate and massage, thereby reducing the surface temperature of the massage balls. After the surface temperature is reduced, the massage balls directly contact the skin around the boil, bringing a noticeable cooling sensation to the skin around the affected area, thereby further alleviating the pain caused by the patient applying the ointment.

[0022] 3. A driving member is provided in the fixed extrusion part, which can drive the coaxially fixed driving gear to rotate. The driving gear is engaged with the rack, so the driving gear will roll along the length direction of the rack, and the moving driving gear drives the two parallel extrusion rollers to move synchronously through the connecting frame. Since the two extrusion rollers clamp the bottom end of the ointment aluminum tube, the two extrusion rollers will gradually squeeze out the ointment in the aluminum tube during the movement, and the ointment will be squeezed out from the center of the applicator head. Since the applicator head is fixed to the wind board through a connecting rod, the applicator head will rotate synchronously with the wind board. The rotating applicator head can evenly apply the extruded ointment to the affected area of ​​the boil, which can effectively assist the patient in applying the ointment to the affected area, greatly reducing the difficulty of the patient's one-handed operation.

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The present application discloses an auxiliary extrusion device for mupirocin ointment, referring to Figure 1 and Figure 2The auxiliary extrusion device for mupirocin ointment includes a detachably connected rotating smearing part 1 and a fixed extruding part 2. The fixed extruding part 2 has a cylindrical appearance as a whole. The interior of the fixed extruding part 2 is hollow and is used to place the ointment aluminum tube 3. The rotating smearing part 1 is coaxially arranged at one end of the fixed extruding part 2. The rotating smearing part 1 can be cylindrical or truncated cone-shaped. In an embodiment of the present application, the detachable connection between the rotating smearing part 1 and the fixed extruding part 2 can be a threaded connection. Specifically, the outer wall of the end of the fixed extruding part 2 close to the rotating smearing part 1 is provided with an external thread, and the inner wall of the rotating smearing part 1 close to one end of the fixed extruding part 2 is provided with an internal thread. When connecting the rotating smearing part 1 and the fixed extruding part 2, it is only necessary to align and rotate the rotating smearing part 1 to fix the rotating smearing part 1 and the fixed extruding part 2 as a whole through a threaded connection.

[0033] Further, refer to Figures 2 to 4 When the auxiliary extrusion device is in use, the ointment aluminum tube 3 can be placed inside the fixed extrusion part 2. In order to fix the ointment aluminum tube 3, two parallel extrusion rollers 21 and two positioning blocks 22 are provided in the fixed extrusion part 2, and in the initial state, the extrusion rollers 21 and the positioning blocks 22 are respectively located at both ends of the aluminum tube 3, for clamping the aluminum tube 3 from both ends, wherein the positioning block 22 is provided on the side of the fixed extrusion part 2 close to the rotating coating part 1, and the two extrusion rollers 21 and the two positioning blocks 22 are symmetrically distributed relative to the axis of the fixed extrusion part 2. A fixed block is provided on the opposite side of the two positioning blocks 22, and the fixed block is fixed on the inner wall of the fixed extrusion part 2. The fixed block corresponds to the positioning block 22 one by one. One side of the positioning block 22 is slidably connected to the corresponding fixed block, and the sliding direction is perpendicular to the axis direction of the fixed extrusion part 2. A compression spring is provided inside the fixed block, one end of the compression spring abuts against the inner wall of the fixed block, and the other end abuts against the end of the positioning block 22. The positioning blocks 22, which can slide within the fixed blocks, can better adapt to aluminum tubes 3 of different sizes by moving their own positions, and the restoring force generated by the compression spring can push the positioning blocks 22 to always clamp the aluminum tube 3. In the embodiment of the present application, the positioning blocks 22 are long, curved blocks, so that the two positioning blocks 22 can better adapt to the outer surface of the aluminum tube 3.

[0034] To extrude the ointment from the aluminum tube 3, the axis of the extrusion roller 21 is perpendicular to the axis of the fixed extrusion section 2. A connecting frame 211 is fixed at each end of the extrusion roller 21. The connecting frame 211 also fixes the ends of the two extrusion rollers 21, so that the two extrusion rollers 21 are connected as a whole through the connecting frames 211 at both ends and move synchronously. Each connecting frame 211 is rotatably connected to a drive gear 212, and the rotation axis of the drive gear 212 is perpendicular to the axis of the extrusion roller 21. At the same time, a driving member 213 is also fixed on the connecting frame 211. The driving member 213 can be a micro motor. The output shaft of the driving member 213 is coaxially fixed with the driving gear 212, so that the driving member 213 can drive the driving gear 212 to rotate. A rack 23 is fixed on the inner wall of the fixed extrusion section 2. The rack 23 extends along the length direction of the fixed extrusion section 2, and the rack 23 corresponds to the driving gear 212 and meshes with each other.

[0035] The two driving members 213 respectively drive the two driving gears 212 to rotate synchronously and at the same speed, and the driving gears 212 are engaged with the rack 23, so the two driving gears 212 will roll along the length direction of the corresponding rack 23 respectively. The moving driving gear 212 drives the two parallel extrusion rollers 21 to move synchronously through the connecting frame 211. In the initial state, the two extrusion rollers 21 clamp the bottom end of the ointment aluminum tube 3, so the two extrusion rollers 21 will gradually squeeze the bottom of the aluminum tube 3 during the movement, thereby squeezing out the ointment in the aluminum tube 3.

[0036] Reference Figures 2 to 7 A rotatable coating head 11 is provided inside the rotating coating part 1, and the rotation axis of the coating head 11 is coaxially arranged with the axis of the fixed extrusion part 2. Specifically, a rotary joint 111 is fixed to the end of the coating head 11 close to the aluminum tube 3, and the rotary joint 111 is rotatably connected to the end of the coating head 11 away from the coating head 11 with a connector 112, and the coating head 11 rotates inside the connector 112 following the rotary joint 111. The interior of the connector 112 is recessed inward to form a receiving space for placing the port of the aluminum tube 3. The rotation axis of the rotary joint 111 is coaxially arranged with the axis of the fixed extrusion part 2, and an extrusion port 113 is coaxially opened inside the rotary joint 111. The extrusion port 113 is connected to the internal receiving space of the connector 112, and one end of the rotary joint 111 extends outward to the center of the coating head 11. In an embodiment of the present application, the coating head 11 is three silicone spheres distributed circumferentially around the axis of the rotary joint 111, and the extrusion port 113 is arranged at the center of the three silicone spheres. When the fixed extrusion part 2 and the rotating application part 1 are fixed together, the end of the aluminum tube 3 is located in the connecting head 112, so that the ointment squeezed out from the aluminum tube 3 can be squeezed out along the extrusion port 113 in the rotating joint 111. At this time, the position where the ointment is extruded is located at the center of the application head 11. The rotating application head 11 can evenly apply the squeezed ointment to the affected area of ​​the boil, which can effectively assist the patient in applying the ointment to the affected area, greatly reducing the difficulty of the patient's one-handed operation.

[0037] Furthermore, four massage balls 4 are provided on the end face of the rotating application portion 1 away from the fixed extrusion portion 2. The massage balls 4 can be made of a metal material with good thermal conductivity, such as stainless steel or iron. The actual number of massage balls 4 can be increased or decreased according to the actual size of the end face of the rotating application portion 1, so that the massage balls 4 can adapt to extrusion devices of different sizes. The surface of the massage balls 4 is smooth, and all the massage balls 4 are distributed in a circular array around the central axis of the fixed extrusion portion 2, so that all the massage balls 4 are distributed around the outer ring of the application head 11. An annular sliding groove 12 is provided on the end face of the rotating application portion 1. The massage balls 4 are all slidably connected in the sliding groove 12, and part of the body of the massage balls 4 is exposed outside the sliding groove 12, so that the massage balls 4 can protrude outside the rotating application portion 1 and can contact the patient's skin.

[0038] To further limit the sliding of the massage balls 4 on the end surface of the rotating application section 1, a scoop plate 5 is provided within the rotating application section 1. Each scoop plate 5 corresponds to each massage ball 4, and its length aligns with the axis of the fixed extrusion section 2. The sidewalls of the scoop plate 5 are slidably connected to the inner wall of the rotating application section 1 via a connecting block. The massage balls 4 are rotationally connected to one end of the scoop plate 5, with the axis of rotation perpendicular to the axis of the application head 11. The scoop plate 5 and the massage balls 4 can move synchronously along the sliding groove 12. To further maintain the smooth movement of the scoop plate 5 and the massage balls 4, both sides of the scoop plate 5 along the axis of rotation of the massage balls 4 are slidably connected to the inner wall of the rotating application section 1 via connectors 112. The sidewalls of the scoop plate 5 away from the massage balls 4 are also slidably connected to the inner wall of the rotating application section 1 via connectors 112.

[0039] To drive the movement of the air board 5 and massage balls 4, four air blowing tubes 13 are fixed to the inner sidewall of the rotating application portion 1. These four air blowing tubes 13 are spaced around the inner wall of the rotating application portion 1. A cold air generating module 24 is also provided within the fixed extrusion portion 2 to provide a cold air flow to the air blowing tubes 13. The air outlet 131 of the air blowing tube 13 is tilted downward toward the sidewall of the air board 5. When the air board 5 passes near the air outlet 131 of the air blowing tube 13, the airflow from the air outlet 131 can move the air board 5. In other embodiments of the present application, the number of air blowing tubes 13 can be increased or decreased according to actual conditions to ensure sufficient airflow to move the air board 5. The cold air generating module 24 is an integrated module, integrating a small exhaust unit and a refrigeration module. A through hole is provided on the sidewall of the fixed extrusion portion 2 corresponding to the cold air generating module 24, allowing the exhaust unit to draw in external air, which is then cooled by the refrigeration module to form a cold air flow.

[0040] To make the airflow more easily blown by the airflow, in the embodiment of the present application, the airflow plate 5 is an arc-shaped plate with its opening facing the air outlet 131 of the air blowing pipe 13. The airflow plate 5 is also thin, making it more easily blown by the airflow. Furthermore, the air blowing pipe 13 also includes an air inlet 132 and an internal air blowing channel 133. The diameter of the air blowing channel 133 gradually decreases along the direction from the air inlet 132 to the air outlet 131 of the air blowing pipe 13, so that the flow cross-section of the airflow gradually decreases during the process of flowing from the air inlet 132 to the air outlet 131, thereby gradually increasing the flow rate of the airflow. When the airflow is blown out from the air outlet 131, the wind speed has been increased to a speed sufficient to blow the airflow plate 5 and the massage balls 4. The air outlet 131 of the air blowing pipe is staggered with the sliding groove 12, so that the cold airflow blown out of the air blowing pipe does not flow directly out of the sliding groove 12. At the same time, the apron plate 5 and the coating head 11 are fixed via a connecting rod 51 so that the apron plate 5 and the coating head 11 rotate synchronously.

[0041] When ointment needs to be applied to the affected area, the cold air generating module 24 provides a cold air flow to the air blowing pipe 13 through the air guide pipe 61 and the air guide groove 6. The air flow will gradually accelerate when it is blown out from the air blowing pipe 13 with a gradually decreasing diameter, so that the air flow has been sufficiently accelerated when it is blown out from the air outlet 131 of the air blowing pipe 13. At this time, the speed of the air flow is faster, and the air flow blows directly to the arc-shaped air scoop plate 5. The air scoop plate 5 will start to rotate in the rotating application part 1 under the impact of the high-speed air flow. The rotating air scoop plate 5 will drive the corresponding massage balls 4 to rotate synchronously, and all the rotating massage balls 4 will rotate around the boil affected area. At this time, the rotating massage balls 4 can massage a circle of skin around the affected area, thereby reducing the pain caused by the patient when applying the ointment and improving the patient's comfort. At the same time, since the cold air generating module 24 provides a cold air flow with a lower temperature, and the massage balls 4 can be made of a metal material with good thermal conductivity, the cold air flow can cool the surface of the massage balls 4 while driving the massage balls 4 to rotate and massage, so that the temperature of the surface of the massage balls 4 is reduced. After the surface is cooled, the massage balls 4 directly contact the skin around the boil, which can bring a significant cooling sensation to the skin around the affected area, thereby further alleviating the pain caused by the patient when applying the ointment; and the cold air flow will collide with the surface of the ventilation plate 5 when blowing towards the surface of the ventilation plate 5, thereby greatly slowing down the flow speed of the cold air flow. At this time, the temperature of the air flow is still relatively low, and the cold air flow will then be blown out from the sliding groove 12. The cold air flow with a lower temperature blows directly on the skin around the affected area, further bringing a cooling sensation to the skin around the affected area.

[0042] An energy storage battery 25 is fixed inside the fixed extrusion part 2 at one end away from the rotating coating head 11. The energy storage battery 25 can supply power to all electrical components inside the auxiliary extrusion device, and the energy storage battery 25 can be a rechargeable battery. When the energy storage battery 25 is almost exhausted, the charger can be used to directly recharge the energy storage battery 25. The rotating coating part 1 and the fixed extrusion part 2 are respectively provided with an air inlet groove 14 and an air outlet groove 26 at one end close to each other. The air inlet groove 14 and the air outlet groove 26 are respectively arranged around the inner wall of the rotating coating part 1 and the fixed extrusion part 2, and the opening of the air inlet groove 14 faces the fixed extrusion part 2, while the opening of the air outlet groove 26 faces the rotating coating part 1. When the rotating coating part 1 and the fixed extrusion part 2 are threadedly connected as one, the air inlet groove 14 and the air outlet groove 26 are merged into a complete air guide groove 6. One side of the air outlet groove 26 is connected to the cold air generating module 24 through multiple air guide pipes 61, and the air inlet 132 of the blowing pipe 13 is connected to the internal space of the air inlet groove 14.

[0043] Furthermore, to further reduce the temperature of the airflow and enable the cold airflow to effectively cool the surface of the massage roller 4, cooling elements (not shown) are embedded within the air inlet slot 14 and the air outlet slot 26 of the fixed extrusion section 2 and the rotating application section 1, respectively. These cooling elements are annular and comprise multiple layers, spaced apart along the axis of the rotating application section 1. A gap is left between adjacent cooling elements for airflow to pass through. Each cooling element exhibits an undulating, wavy appearance and is made of a phase-change, heat-absorbing material. In this embodiment of the present application, the cooling element can be made of paraffin, a composite phase-change material, or a low-temperature phase-change material, enabling it to effectively absorb heat and cool the airflow at room temperature. When the airflow enters the air guide groove 6 from the air guide pipe 61, the cooled airflow flows through the gaps left between the multiple layers of cooling elements, extending the flow path of the airflow, allowing the cooling elements to fully cool the airflow. In addition, the cooling elements are in an undulating wave shape, further extending the flow path of the airflow on the surface of the cooling elements, thereby effectively cooling the airflow. In other embodiments of the present application, if the ambient temperature is not high, the refrigeration module in the cold air generating module 24 can be directly removed, and the airflow can be cooled only by the cooling elements. In this case, a cooling element can also be set in the air guide pipe 61, so that the airflow can cool the massage balls 4 while reducing the manufacturing cost of the auxiliary extrusion device.

[0044] In this embodiment, ointment extrusion and application are performed in two separate steps, each controlled by two operating buttons (not shown) on the fixed extrusion unit 2. Both operating buttons are electrically connected to a control unit (not shown) within the auxiliary extrusion device, which may be a circuit board with a control chip. When the ointment needs to be extruded, the operating buttons control the synchronous operation of the driver 213 to extrude the ointment. Subsequently, another operating button controls the cold air generation module 24 to generate a cold air flow, thereby controlling the rotation of the ventilation plate 5.

[0045] The cold air flow generated by the cold air generating module 24 flows into the air guide groove 6 formed by merging the air outlet groove 26 and the air inlet groove 14 through the air guide pipe 61 , and the cold air flow is redistributed in the air guide groove 6 , and then blown out through each blowing pipe 13 .

[0046] The implementation principle of the auxiliary extrusion device for mupirocin ointment in the embodiment of the present application is as follows: two moving driving gears 212 drive two parallel extrusion rollers 21 to move synchronously through a connecting frame 211. During the movement, the extrusion rollers 21 gradually squeeze the bottom of the aluminum tube 3, thereby squeezing the ointment in the aluminum tube 3 from the outlet to the surface of the affected area. Then, the cold air flow blows the scoop plate 5 to slide, and the scoop plate 5 drives the corresponding massage balls 4 to move in circles along the sliding groove 12, so that the massage balls 4 can massage the skin around the affected area, thereby relieving the patient's pain. At the same time, the cold air flow arc can cool the surface of the massage balls 4, so that the massage balls 4 after the surface is cooled directly contact the skin around the boil affected area, which can bring a significant cooling sensation to the skin around the affected area, thereby further alleviating the pain caused by the patient when applying the ointment. The scoop plate 5 is connected to the applicator head 11 through a connecting rod 51, so that the scoop plate 5 and the applicator head 11 rotate synchronously, thereby achieving cooling and massaging around the affected area while applying the ointment.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
