[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 an external antibiotic with strong antibacterial activity against Gram-positive cocci (such as Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, etc.), and also has a certain effect on methicillin-resistant Staphylococcus aureus (MRSA). Mupirocin ointment is often used to reduce skin inflammatory reactions, relieve symptoms such as redness, swelling, pain, and itching such as boils, and can effectively promote the repair of damaged skin tissue and accelerate wound healing; it can also promote healing by stimulating keratinocyte proliferation and increasing growth factors. It is especially suitable for damaged or inflamed skin and can reduce the risk of infection spread.

[0003] Mupirocin ointment is a paste-like medicine, usually contained in a special aluminum tube. When using it, the ointment needs to be squeezed out of the aluminum tube.

[0015] In summary, the present application includes at least one of the following beneficial effects: 1. A plurality of massage balls that can rotate in a circle are arranged at the end of the rotating application part, and the massage balls protrude from the rotating application part. Therefore, when applying the ointment to the affected part, the massage balls are in direct contact with the patient's skin. When the ointment needs to be applied to the affected part, 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 blowing pipe with a gradually decreasing diameter, so that 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 speed of the air flow is relatively fast, and the air flow blows directly to the arc-shaped wind board. The wind board will start to rotate in the rotating application part under the impact of the high-speed air flow. The rotating wind board will drive the corresponding massage balls to rotate synchronously, and all the rotating massage balls will rotate around the furunculosis affected part. At this time, the rotating massage balls can massage a circle of skin around the affected part, thereby alleviating the pain caused by the patient when applying the ointment and improving the patient's comfort. 2. Since the cold air generation module provides a relatively low-temperature cold air flow, and the massage balls can be made of metal materials with good thermal conductivity, the cold air flow can cool down the surface of the massage balls while driving the massage balls to rotate and massage, so that the surface temperature of the massage balls is reduced. After the surface temperature is reduced, the massage balls directly contact the skin around the affected area of ​​the boil, which can bring a significant cooling feeling to the skin around the affected area, thereby further alleviating the pain caused by the patient when applying the ointment; 3. A driving member is provided in the fixed extrusion part, and the driving member can drive the coaxially fixed driving gear to rotate. The driving gear is meshed with the rack, so the driving gear will roll along the length direction of the rack, and the moving driving gear drives 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 application head. Since the application head is connected and fixed to the wind board through a connecting rod, the application head will rotate synchronously with the wind board. The rotating application 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.

[0018] The following is combined with Figure 1-7 This application is described in further detail.

[0019] The present application embodiment discloses an auxiliary extrusion device for mupirocin ointment, referring to Figure 1 and Figure 2 The 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 the 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 by threaded connection.

[0020] Further, see 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 arranged in the fixed extrusion part 2, and in the initial state, the extrusion rollers 21 and the positioning blocks 22 are respectively located at the two ends of the aluminum tube 3, which are used to clamp the aluminum tube 3 from both ends, wherein the positioning block 22 is arranged on one 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 arranged 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, and one side of the positioning block 22 is slidably connected in the corresponding fixed block, and the sliding direction is perpendicular to the axis direction of the fixed extrusion part 2. A compression spring is arranged inside the fixed block, and 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 block 22 that can slide in the fixed block can better adapt to aluminum tubes 3 of different sizes by moving its own position, and the restoring force generated by the compression spring can push the positioning block 22 to always clamp the aluminum tube 3. In the embodiment of the present application, the positioning block 22 is a long arc block, so that the two positioning blocks 22 can better adapt to the outer surface of the aluminum tube 3.

[0021] To extrude the ointment in the aluminum tube 3, the axis direction of the extrusion roller 21 is perpendicular to the axis direction of the fixed extrusion part 2. A connection frame 211 is fixed at each end of the extrusion roller 21. The connection frame 211 is fixedly connected to the ends of the two extrusion rollers 21 at the same time, so that the two extrusion rollers 21 are connected as a whole through the connection frames 211 at both ends for synchronous movement. Each connection frame 211 is rotatably connected to a driving gear 212, and the rotation axis of the driving gear 212 is perpendicular to the axis direction of the extrusion roller 21. At the same time, a driving member 213 is also fixed on the connection frame 211. The driving member 213 can be a micro motor, and 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 part 2, and the rack 23 extends along the length direction of the fixed extrusion part 2, and the rack 23 corresponds to the driving gear 212 one by one and meshes with each other.

[0022] 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 meshed with the rack 23, so the two driving gears 212 will roll along the length direction of the corresponding rack 23 respectively, and the moving driving gears 212 drive 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.

[0023] Reference Figures 2 to 7 , a rotatable coating head 11 is arranged inside the rotating coating part 1, and the rotation axis of the coating head 11 is arranged coaxially with the axis of the fixed extrusion part 2. Specifically, a rotating joint 111 is fixed to the end of the coating head 11 close to the aluminum tube 3, and the rotating joint 111 is rotatably connected to the end of the coating head 11 away from the coating head 11, and the coating head 11 rotates in the connector 112 following the rotating joint 111. The interior of the connector 112 is recessed inward to form a accommodating space for placing the port of the aluminum tube 3. The rotation axis of the rotating joint 111 is arranged coaxially with the axis of the fixed extrusion part 2, and an extrusion port 113 is coaxially opened inside the rotating joint 111, and the extrusion port 113 is connected to the internal accommodating space of the connector 112, and one end of the rotating joint 111 extends outward to the center of the coating head 11. In the embodiment of the present application, the coating head 11 is three silicone spheres distributed circumferentially around the axis of the rotating 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.

[0024] Furthermore, four massage balls 4 are arranged on the end face of the rotating application part 1 away from the fixed extrusion part 2. The massage balls 4 can be made of metal materials 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 part 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 arranged in a circular array around the central axis of the fixed extrusion part 2, so that all the massage balls 4 are distributed around the outer ring of the application head 11. The end face of the rotating application part 1 is provided with an annular sliding groove 12, and 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 part 1, so as to be able to contact the patient's skin.

[0025] In order to further limit the massage ball 4 from sliding on the end surface of the rotating coating part 1, a wind board 5 is provided in the rotating coating part 1. The wind board 5 corresponds to the massage ball 4 one by one, and the length direction of the wind board 5 is consistent with the axis direction of the fixed extrusion part 2. The side wall of the wind board 5 is slidably connected to the inner wall of the rotating coating part 1 through a connecting block. The massage ball 4 is rotatably connected to one end of the wind board 5, and the rotation axis is perpendicular to the axis of the coating head 11. The wind board 5 and the massage ball 4 can move synchronously along the sliding groove 12. In order to further maintain the smoothness of the movement of the wind board 5 and the massage ball 4, both sides of the wind board 5 along the rotation axis direction of the massage ball 4 are slidably connected to the inner wall of the rotating coating part 1 through the connecting head 112, and at the same time, the side wall of the wind board 5 away from the massage ball 4 is also slidably connected to the inner wall of the rotating coating part 1 through the connecting head 112.

[0026] In order to drive the air board 5 and the massage ball 4 to move, four air blowing pipes 13 are fixed on the inner wall of the rotating coating part 1, and the four air blowing pipes 13 are spaced around the inner wall of the rotating coating part 1. At the same time, a cold air generating module 24 is arranged in the fixed extrusion part 2 to provide a cold air flow for the air blowing pipe 13. The air outlet 131 of the air blowing pipe 13 is tilted downward toward the side wall of the air board 5. When the air board 5 passes near the air outlet 131 of the air blowing pipe 13, the air flow blown out from the air outlet 131 can blow the air board 5 to move. In other embodiments of the present application, the number of air blowing pipes 13 can be increased or decreased according to actual conditions so that there is sufficient air flow to blow the air board 5 to move. The cold air generating module 24 is an integrated module, which integrates a small air extraction component and a refrigeration module. At the same time, a through hole is opened at the side wall of the fixed extrusion part 2 corresponding to the cold air generating module 24, which can be used for the air extraction component to extract external air, and then the air is cooled by the refrigeration module to form a cold air flow.

[0027] In order to make the airflow plate 5 easier to be blown by the airflow, in the embodiment of the present application, the airflow plate 5 is an arc-shaped plate with an opening facing the air outlet 131 of the air blowing pipe 13, and the thickness of the airflow plate 5 is relatively thin, so that the airflow plate 5 is easier to be blown by the airflow. Further, the air blowing pipe 13 also includes an air inlet 132 and an internal air blowing channel 133. Along the direction from the air inlet 132 to the air outlet 131 of the air blowing pipe 13, the diameter of the air blowing channel 133 gradually decreases, so that in the process of flowing from the air inlet 132 to the air outlet 131, the flow cross section of the airflow gradually decreases, so that the flow rate of the airflow gradually increases, so that 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 ball 4. The air outlet 131 of the air blowing pipe is staggered with the sliding groove 12, so that the cold airflow blown out from the air blowing pipe does not flow out directly from the sliding groove 12. At the same time, the air vent plate 5 and the coating head 11 are fixed via a connecting rod 51 so that the air vent plate 5 and the coating head 11 rotate synchronously.

[0028] 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 guiding pipe 61 and the air guiding 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 relatively fast, and the air flow blows directly to the arc-shaped air vent plate 5. The air vent plate 5 will start to rotate in the rotating application part 1 under the impact of the high-speed air flow. The rotating air vent 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 relatively low 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 surface temperature of the massage balls 4 is reduced. After the surface is cooled, the massage balls 4 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; and the cold air flow will collide with the surface of the wind board 5 when blowing toward the surface of the wind board 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, and the cold air flow with a relatively low temperature will directly blow on the skin around the affected area, further bringing a cooling sensation to the skin around the affected area.

[0029] 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 power of the energy storage battery 25 is almost exhausted, the charger can be directly used to charge 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, and 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, and one side of the air outlet groove 26 is connected to the cold air generating module 24 through a plurality of air guide pipes 61, and the air inlet 132 of the air blowing pipe 13 is connected to the internal space of the air inlet groove 14.

[0030] In addition, in order to further reduce the temperature of the airflow so that the cold airflow can effectively cool the surface of the massage ball 4, the fixed extrusion part 2 and the rotating application part 1 are respectively embedded with cooling parts (not shown) in the air inlet groove 14 and the air outlet groove 26. The cooling parts are annular and have multiple layers. The multiple layers of cooling parts are spaced along the axis direction of the rotating application part 1, and there is a gap between two adjacent cooling parts for airflow to pass through. Each cooling part has an undulating wavy appearance, and the cooling part is made of phase change heat-absorbing material. In the embodiment of the present application, the cooling part can be made of paraffin, composite phase change material or low-temperature phase change material, so that the cooling part can effectively absorb heat and cool the airflow at room temperature. When the airflow enters the air guide groove 6 from the air guide duct 61, the refrigerated airflow flows in the gaps left between the multiple layers of cooling components, extending the flow path of the airflow, so that the cooling components can fully cool the airflow, and the cooling components are in an undulating wave shape, further extending the flow path of the airflow on the surface of the cooling components, 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 by the cooling components only. At this time, a cooling component can also be set in the air guide duct 61, so that the airflow can cool the massage balls 4 while reducing the manufacturing cost of the auxiliary extrusion device.

[0031] In the embodiment of the present application, the extrusion and application of the ointment are carried out in two steps, which can be controlled by two operating buttons (not shown) on the fixed extrusion part 2, respectively. The two operating buttons are electrically connected to the control unit (not shown) inside the auxiliary extrusion device, and the control unit can be composed of a circuit board with a control chip. When the ointment needs to be extruded, the driving member 213 is controlled to operate synchronously by the operating button to extrude the ointment; then another operating button is used to control the cold air generation module 24 to generate a cold air flow to control the rotation of the ventilating plate 5.

[0032] 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 the cold air flow is blown out through each blowing pipe 13 .

[0033] 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 the connecting frame 211, and the extrusion rollers 21 gradually squeeze the bottom of the aluminum tube 3 during the movement, so that the ointment in the aluminum tube 3 is squeezed out from the outlet to the surface of the affected part, and then the air flow blows the air vent plate 5 to slide, and the air vent plate 5 drives the corresponding massage ball 4 to move in a circle along the sliding groove 12, so that the massage ball 4 can massage the skin around the affected part, thereby relieving the patient's pain. At the same time, the cold air flow arc can cool the surface of the massage ball 4, so that the massage ball 4 after the surface is cooled directly contacts the skin around the furuncle affected part, which can bring obvious cooling feeling to the skin around the affected part, thereby further alleviating the pain caused by the patient when applying the ointment, and the air vent plate 5 is connected to the application head 11 through the connecting rod 51, so that the air vent plate 5 and the application head 11 rotate synchronously, thereby realizing cooling and massaging the area around the affected part while applying the ointment.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
