Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a delivery device for mupirocin ointment. Background Technology

[0002] Mupirocin ointment is a topical antibiotic whose main ingredient is mupirocin. Its mechanism of action is to inhibit bacterial protein synthesis, thereby exerting an antibacterial effect and treating skin infections. Currently, the common method of applying mupirocin ointment is to squeeze it onto the wound, spread it evenly on the wound surface using a cotton swab or finger, and then cover and bandage with sterile gauze. This helps prevent and treat wound infection and promotes wound healing.

[0003] During the above procedures, when the ointment is squeezed out, its shape will match the opening of the ointment dispenser, usually cylindrical. This makes it difficult to fully cover the wound, requiring the use of a cotton swab or finger to spread the ointment evenly. Firstly, controlling the amount of ointment dispensed is difficult. Using too much may lead to medication waste, increase skin burden, and reduce local skin permeability, hindering wound healing. Excess ointment can also easily smudge onto clothing, causing inconvenience. Conversely, using too little ointment will not effectively cover the wound and surrounding infected area, failing to fully exert the drug's antibacterial effect, potentially leading to poor infection control and affecting treatment outcomes.

[0004] Secondly, it is important to ensure that the ointment is applied evenly to the wound during the application process. When applying the ointment, the cotton swab and fingers need to come into contact with the wound, which may cause pain to the patient.

[0005] In conclusion, manual application has many drawbacks, affecting wound healing efficiency and causing discomfort to patients. Summary of the Invention

[0006] The purpose of this application is to provide a delivery device for mupirocin ointment, which can relieve patient discomfort while evenly applying mupirocin ointment to the wound and improving wound healing efficiency.

[0007] This application provides a drug delivery device for mupirocin ointment, which adopts the following technical solution:

[0008] A delivery device for mupirocin ointment, comprising, arranged sequentially from bottom to top:

[0009] The storage section includes a sliding sleeve and a storage box slidably disposed within the sliding sleeve, the storage box being used to store mupirocin ointment;

[0016] Optionally, a limiting boss is provided on the inner wall of the connecting ring, the edge of the gauze rests on the limiting boss, the fixing shell can be inserted into the connecting ring and fix the gauze on the limiting boss, the limiting boss and the fixing shell are magnetically connected, and the middle area of ​​the gauze abuts against the reset block.

[0017] Optionally, the temperature regulation component includes a composite temperature control tube coiled inside the reset block. The composite temperature control tube includes, from the inside out, a heating layer, an insulating layer, a heat-conducting layer, a cooling layer, and an outer shell layer. The heating layer can heat the reset body, while the cooling layer is attached to the outside of the heat-conducting layer to achieve active cooling.

[0018] Optionally, the cooling layer uses a semiconductor refrigeration chip, and multiple semiconductor refrigeration chips are densely attached to the outer wall of the heat-conducting layer. The inner wall of the fixed housing is provided with a power source for driving the composite temperature control tube to heat or cool.

[0019] Optionally, the power supply includes an AC power supply for driving the heating layer to generate heat and a low-voltage DC power supply for driving the semiconductor cooling chip to generate heat. A conductive sheet is attached to the inner wall of the locking groove. The conductive sheets in different locking grooves are connected to different types of power supplies. The locking rod is made of conductive material and is electrically connected to the composite temperature control tube.

[0020] Optionally, the rotating cylinder has a vertically arranged sliding hole on its peripheral wall, the sliding sleeve has an annular sliding groove on its inner wall, and the storage box has a sliding end that is fixedly connected to the sliding hole and the annular sliding groove.

[0021] Optionally, the slide sleeve is provided with an observation window, which allows observation of changes in the liquid level inside the storage box, and the observation window is provided with scale markings.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Place the gauze inside the connecting ring, connect the squeezing part to the connecting part, and the edge of the gauze is attracted between the bottom of the fixed shell and the limiting boss. The protrusion applies a pushing force to the middle of the gauze, causing the gauze to bulge outward. Control the storage box to rise in the sliding sleeve until the protruding part of the gauze contacts the mupirocin ointment in the storage box, so that the protruding part of the gauze is adhered to the mupirocin ointment. Then separate the connecting part from the storage part, align the connecting ring with the wound, and press the sliding block so that the gauze covers the wound. The reset block deforms and fits against the body surface. At the same time, as the fixed shell moves down, the reset block can detach the edge of the gauze from between the fixed shell and the limiting boss. The gauze passes through the connecting ring and fits against the body surface.

[0024] In this application, gauze is applied to the wound in contact with mupirocin ointment before the gauze is covered, which revolutionizes the traditional method of medication application and has the following advantages:

[0025] First, by pressing the gauze with the repositioning block, the gauze is made to fit completely against the wound. During the pressing process, the mupirocin ointment is squeezed and overflows towards the periphery of the wound, thereby improving the evenness of the mupirocin ointment application to the wound.

[0026] Secondly, when the repositioning block is squeezed, it deforms, allowing it to adhere to the body surface. This enables the gauze to fully adhere to the body, reducing the possibility of gaps between the gauze and the wound caused by uneven body surfaces. This further improves the coverage of the mupirocin ointment on the wound.

[0027] Thirdly, when mupirocin ointment is routinely applied to a wound using a cotton swab or finger, the nerve endings at the wound site are exposed and quite sensitive. When the cotton swab or finger comes into direct contact, the pressure, temperature, and other stimuli directly act on the nerve endings, generating pain signals that are transmitted to the brain, causing pain. Gauze, on the other hand, acts as a buffer, dispersing pressure and reducing direct stimulation of the nerve endings, thereby alleviating pain.

[0028] Secondly, when people directly touch a wound, they tend to focus more on the wound, which psychologically amplifies the feeling of pain. However, applying pressure through gauze can distract attention to some extent and give a psychological suggestion that the wound is relatively safe and not directly touched, thus reducing the subjective pain perceived.

[0029] Fourthly, the temperature regulating component can adjust the temperature of the repositioning block, causing it to rise or fall. When there is significant local swelling and the wound is in the early stage of inflammation, the temperature regulating component lowers the temperature of the repositioning block, thereby achieving a cold compress effect on the wound, reducing edema around the incision, and accelerating the fading of bruising. When the wound is in the later stage of recovery, with bruising or induration, the temperature regulating component raises the temperature of the repositioning block, thereby achieving a hot compress effect on the wound, promoting blood circulation and drug absorption.

[0030] 2. When the telescopic rod and the reset block are connected, when the reset block comes into contact with the wound, the telescopic rod will move towards the elastic element when the reset block encounters resistance, compressing the elastic element. The elastic buffer can reduce the damage to the wound tissue and also reduce pain.

[0031] 3. Install the conductive plate of the power supply in the locking groove of the locking assembly. Before the preparation work, the power supply provides power to the temperature regulation assembly to heat up or cool down the reset block. When the reset block moves down, the conductive plate disconnects from the locking rod, realizing the power failure protection function of the temperature regulation assembly.

[0032] 4. The storage section, connecting section, and extrusion section are integrated and detachable, with good sealing performance, reducing the chance of mupirocin ointment in the storage box coming into contact with the outside air and causing oxidation of the ointment, thus facilitating the preservation of the ointment.

[0039] Reference Figure 1 This application provides a delivery device for mupirocin ointment, referring to... Figure 1 and Figure 2 The device includes a storage section 1, a connecting section 2, and a squeezing section 3 connected sequentially from bottom to top. The storage section 1 is used to store mupirocin ointment. The two ends of the connecting section 2 are detachably connected to the storage section 1 and the squeezing section 3, respectively. The connecting section 2 is used to accommodate gauze, which can contact the mupirocin ointment in the storage section 1. The squeezing section 3 includes a fixed housing 31 and a squeezing assembly that slides vertically inside the fixed housing 31. The squeezing assembly is used to apply a pushing force to the gauze and adhere the gauze to the wound.

[0040] Reference Figure 2 and Figure 3 The storage unit 1 includes a rotating cylinder 11, a sliding sleeve 12, and a storage box 13. A rotating handle is integrally formed at the bottom of the rotating cylinder 11. The sliding sleeve 12 is fitted onto the rotating cylinder 11, and the storage box 13 is disposed within the inner cavity of the rotating cylinder 11. Two corresponding vertical sliding holes 111 are formed on the inner wall of the rotating cylinder 11. Two limiting holes 112 are vertically connected to the two ends of each vertical sliding hole 111, and the two limiting holes 112 are opened in opposite directions. Two spirally arranged annular sliding grooves 121 are formed on the inner wall of the sliding sleeve 12. An opening is provided at the top of the storage box 13, and two sliding ends 131 are provided on the outer wall of the storage box 13. One end of each sliding end 131 passes through the sliding hole 111 and is engaged in the annular sliding groove 121.

[0041] Hold the sliding sleeve 12 and turn the handle. The sliding end 131 first slides from the limiting hole 112 to the sliding hole 111. Continue to rotate the rotating cylinder 11. When the sliding end 131 moves along the annular sliding groove 121, the sliding hole 111 rotates with the annular sliding groove 121, so that the storage box 13 moves upward as it rotates until the mupirocin ointment contacts the protrusion 331 of the gauze.

[0042] Reference Figure 2 An observation window 14 is provided on the upper part of the sliding sleeve 12, and the bottom of the observation window 14 is flush with the bottom of the storage box 13 at the highest point inside the rotating cylinder 11. Both the rotating cylinder 11 and the storage box 13 are colorless. The observation window 14 allows observation of the contact between the mupirocin ointment and the gauze inside the storage box 13, and also allows observation of the amount of mupirocin ointment stored in the storage box 13. The observation window 14 is provided with scale marks 15. When the storage box 13 moves to the highest point inside the rotating cylinder 11, the scale marks 15 clearly show the amount of mupirocin ointment in the storage box 13, as well as the amount that needs to be replenished.

[0043] Reference Figure 2 The connecting part 2 includes a connecting ring 21. An annular limiting boss 22 is provided on the inner wall of the connecting ring 21. A magnetic element is provided on the bottom wall of the limiting boss 22. The bottom of the fixed housing 31 is magnetically connected to the limiting boss 22. The outer wall of the bottom of the connecting ring 21 is provided with an external thread. The inner wall of the rotating cylinder 11 is provided with an internal thread that engages with the external thread. A circular gauze can be placed inside the connecting ring 21. The edge of the gauze rests on the limiting boss 22. The middle part of the gauze is aligned with the inner cavity of the connecting ring 21 and can pass through the connecting ring 21 to contact the mupirocin ointment in the storage box 13.

[0044] Reference Figure 2 The connecting part 2 and the storage part 1 are connected by threads. On the one hand, it is convenient to disassemble and assemble the connecting part 2 and the storage part 1, and to conveniently feed the storage box 13. On the other hand, the threaded connection can ensure the airtightness of the connecting part 2 and the storage part 1, reduce the air entering the storage part 1 from the connection, and thus improve the shelf life of mupirocin ointment.

[0045] The compression component applies pressure to the gauze, thus adhering it to the wound. The fixing housing 31 can be inserted into the connecting ring 21. The gauze is sheet-shaped, and its size is larger than the inner cavity of the connecting ring 21. Therefore, the edges of the gauze are positioned on the limiting boss 22, and the bottom of the fixing housing 31 can be magnetically connected to the limiting boss 22, thereby fixing the edges of the gauze between the fixing housing 31 and the limiting boss 22. This facilitates unfolding the gauze, allowing mupirocin ointment to adhere to the portion of the gauze that passes through the inner cavity of the connecting ring 21. The gauze is for single use only; when reused, it needs to be replaced periodically.

[0046] Reference Figure 4 The extrusion assembly includes a sliding block 32 and a reset block 33 slidably disposed in the inner cavity of the fixed housing 31. The sliding block 32 and the reset block 33 are connected. The reset block 33 is made of elastic silicone. The part of the bottom of the reset block 33 that protrudes from the fixed housing 31 is a protrusion 331. When the fixed housing 31 is fixed with the connecting ring 21, the protrusion 331 pushes the middle part of the gauze through the inner cavity of the connecting ring 21, so that the mupirocin ointment can contact the gauze of the protrusion 331.

[0047] Reference Figure 4 The sliding block 32 has several through holes 34 inside. A fixed sleeve 35 is fixedly connected inside the through hole 34. A telescopic rod 36 is slidably arranged inside the fixed sleeve 35. One end of the telescopic rod 36 extends out of the through hole 34 and is fixedly connected to the reset block 33. A sealing ring is provided at the opening of the through hole 34. The other end of the telescopic rod 36 is connected to an elastic element 37, which is a spring. The other end of the elastic element 37 is fixedly connected to the inner wall of the through hole 34.

[0048] When gauze needs to be applied to the wound, the sliding block 32 is pushed to slide within the fixed housing 31. The telescopic rod 36 pushes the reset block 33 towards the gauze. As the reset block 33 pushes the gauze, the edge of the gauze detaches from the fixed housing 31 and the limiting boss 22, and passes through the connecting ring 21 to adhere to the skin. When the reset block 33 first contacts the wound, it applies a reverse thrust to the telescopic rod 36, causing the telescopic rod 36 to compress the elastic element 37. The remaining parts will experience elastic buffering after contacting the skin, thus causing the reset block 33 to deform and adhere to the skin. This reduces the possibility of gaps between the gauze and the wound due to uneven skin, which could prevent the mupirocin ointment from fully covering the wound, thereby improving the full contact of the mupirocin ointment with the wound.

[0049] At the same time, the gauze is pressed by the reset block 33, so that the gauze is completely attached to the wound. During the pressing process, the mupirocin ointment is squeezed and overflows towards the periphery of the wound, thereby improving the uniformity of the mupirocin ointment application to the wound.

[0050] Secondly, when mupirocin ointment is applied to the wound using a cotton swab or finger, the nerve endings at the wound site are exposed and quite sensitive. When the cotton swab or finger comes into direct contact, the pressure, temperature, and other stimuli directly act on the nerve endings, generating pain signals that are transmitted to the brain, causing pain. Gauze, on the other hand, acts as a buffer, dispersing pressure and reducing direct stimulation of the nerve endings, thereby alleviating pain.

[0051] When people directly touch a wound, they tend to focus more on the wound and psychologically amplify the feeling of pain. However, applying pressure through gauze can distract attention to some extent and give a psychological suggestion that it is relatively safe and that the wound is not being touched directly, thus reducing the subjective pain perceived.

[0052] Reference Figure 4 A locking component 4 is provided inside the reset block 33. The locking component 4 is used to fix the relative position of the reset block 33 and the fixed housing 31, so that the reset block 33 is not easy to slide within the fixed housing 31 due to gravity. A plurality of locking grooves 41 are provided on the inner wall of the fixed housing 31. The locking component 4 includes a plurality of grooves 43 formed on the side wall of the reset block 33. A locking rod 42 is slidably disposed in the groove 43. One end of the locking rod 42 is fixedly connected to a locking spring 44. The other end of the locking spring 44 is connected to the inner wall of the groove 43. The other end of the locking rod 42 is cylindrical and can be inserted into the locking groove 41. A guide slope is provided on the side wall of the locking groove 41. A sliding groove 45 communicating with the locking groove 41 is provided on the inner wall of the fixed housing 31. The length of the sliding groove 45 limits the sliding distance of the reset block 33 within the fixed housing 31.

[0053] When the reset block 33 is pushed toward the guide slope, the locking rod 42 compresses the locking spring 44 and retracts into the groove 43. At this time, the reset block 33 can move vertically downward in the inner cavity of the fixed housing 31.

[0054] Reference Figure 4 The reset block 33 is provided with a temperature regulating component 5. The temperature regulating component 5 includes a composite temperature control tube 51 coiled inside the reset block 33. The composite temperature control tube 51 is located in the edge area of ​​the reset block 33 and is used to regulate the temperature of the edge of the reset block 33, so as to apply hot or cold compresses to the skin around the wound.

[0055] Reference Figure 4 and Figure 5 The composite temperature control tube 51 comprises, from the inside out, a heating layer 511, an insulating layer 512, a heat-conducting layer 513, a cooling layer 514, and an outer shell layer 515. The heating layer 511 is a metal resistance wire. The insulating layer 512 is magnesium oxide powder filled between the heating layer 511 and the heat-conducting layer 513, possessing high temperature resistance, strong insulation, and heat transfer properties. The heat-conducting layer 513 is a metal sleeve that encloses the insulating layer 512, providing mechanical support and rapidly conducting heat to the outside. The cooling layer 514 is a semiconductor cooling chip attached to the outside of the sleeve, achieving active cooling through the Peltier effect, forming a unified heating and cooling structure with the heating layer 511. The outer shell layer 515 is a protective layer, primarily a plastic shell, protecting the cooling layer 514. In this embodiment, when heating through the heating layer 511, the heating temperature is controlled below 35 °C to prevent burns to users or the mupirocin ointment from becoming ineffective.

[0056] Reference Figure 4 and Figure 5 The composite temperature control tube 51 also includes a power supply 52 disposed within the fixed housing 31. The power supply 52 includes an AC power supply 52 for driving the heating layer 511 to generate heat and a low-voltage DC power supply 52 for driving the semiconductor cooling chip to generate heat. A conductive sheet 53 electrically connected to the power supply 52 is fixedly connected to the inner wall of the locking groove 41. The conductive sheets 53 in different locking grooves 41 are respectively connected to different types of power supplies 52, and the locking rod 42 is made of conductive material. The end of the locking rod 42 is electrically connected to the composite temperature control tube 51. In this embodiment, the locking rod 52 can be disposed at different positions depending on the thickness of the fixed housing 31, or it can be disposed on the outer wall of the fixed housing 31.

[0057] During the preparation phase, when the locking rod 42 is inserted into the locking groove 41, the power supply 52 supplies power to the composite temperature control tube 51, which heats or cools the reset block 33. The specific situation needs to be judged according to the patient's wound condition. When the wound has obvious local swelling and is in the early stage of inflammation, the AC power supply 52 is turned off, and the low-voltage DC power supply 52 supplies power to the composite temperature control tube 51, which causes the semiconductor cooling chip to absorb heat and cool down, thus cooling the reset block 33. When the reset block 33 presses the gauze, it can simultaneously cool the skin around the wound.

[0058] When the wound is in the later stage of recovery, with bruising or hardening, the low-voltage DC power supply 52 is turned off, and the temperature regulating component 5 increases the temperature of the reset block 33, thereby achieving the effect of hot compress on the wound, promoting blood circulation and drug absorption.

[0059] When the reset block 33 is pushed down, the locking rod 42 compresses the locking spring 44 and retracts into the groove 43. At this time, the conductive sheet 53 separates from the locking rod 42. When the reset block 33 is in indirect contact with the locking spring 44, the composite temperature control tube 51 is in a de-energized state, which reduces the harm to the human body in the event of leakage and realizes the power-off protection function of the temperature regulation component 5.

[0060] The implementation principle of a drug delivery device for mupirocin ointment according to an embodiment of this application is as follows: the connecting ring 21 is separated from the fixed housing 31, gauze is placed inside the connecting ring 21, and then the fixed housing 31 is inserted into the limiting boss 22 to fix the gauze. The protrusion 331 drives the middle part of the gauze to pass through the connecting ring 21, connects to the sliding sleeve 12, and rotates the rotating handle so that the storage box 13 moves upward in the rotating cylinder 11. The liquid surface of mupirocin ointment is observed to contact the gauze of the protrusion 331 in the observation window 14 until the mupirocin ointment adheres to the surface of the gauze of the protrusion 331.

[0061] Depending on the condition of the wound, determine whether to use the heating layer 511 or the cooling layer 514, and disconnect the power supply 52 of the other. When the locking rod 42 is in the locking groove 41, power is supplied to the composite temperature control tube 51, causing the composite temperature control tube 51 to heat up or cool down, thereby increasing or decreasing the temperature of the edge of the reset block 33 accordingly.

[0062] Separate the connecting part 2 from the storage part 1, align the connecting ring 21 with the wound, push the sliding block 32, and the locking rod 42 slides on the guide slope into the sliding groove 45. When the reset block 33 pushes the gauze, the edge of the gauze separates from the fixed housing 31 and the limiting boss 22, and passes through the connecting ring 21 to adhere to the skin. When the part of the reset block 33 first contacts the wound, it will apply a reverse thrust to the telescopic rod 36, causing the telescopic rod 36 to compress the elastic element 37. The remaining parts will experience elastic buffering after contacting the skin, thereby causing the reset block 33 to deform and adhere to the skin. This reduces the possibility that gaps exist between the gauze and the wound due to uneven skin, which would prevent the mupirocin ointment from fully covering the wound, thus improving the full contact of the mupirocin ointment with the wound.

[0063] Applying hot or cold compresses to the edge of the repositioning block 33 around the wound can improve the wound's healing effect.

[0064] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
