Description

Technical Field

[0001] This utility model relates to the field of skin medication tools, specifically a portable drug application device for dermatology. Background Technology

[0002] Portable medication application tools, such as disposable cotton swabs, disposable plastic clips, and cotton balls, can be used to pick up medication and apply it to damaged skin. However, medications come in both ointment and liquid forms. While cotton swabs and cotton balls can evenly apply ointment-like medications, the gaps between them can absorb some of the medication, leading to waste. When applying liquid medications, cotton swabs pick up too little, requiring multiple applications to cover a large area, while cotton balls pick up too much, absorbing excessive amounts. When a cotton ball is removed from the medication bottle, the loose texture of the cotton ball causes the medication to drip onto the floor, resulting in significant waste. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1: Please refer to Figures 1-4 The illustration shows a portable dermatological drug application device, which includes: a limiting sleeve 1 and a rod 7 located inside the limiting sleeve 1. The rod 7 is provided with a silicone paddle 8 and a sterile gauze ball 9 at its two ends, respectively.

[0038] Also includes:

[0039] The first connecting component is located between the rod body 7 and the silicone paddle 8;

[0040] The second connecting component is located between the rod body 7 and the sterile gauze ball 9;

[0041] A sliding component is disposed between the rod 7 and the limiting sleeve 1, and is used for axial movement of the rod 7 inside the limiting sleeve 1.

[0042] The first connecting component includes a threaded sleeve 13 fixed to one end of the silicone paddle 8 near the rod 7. The rod 7 has a threaded portion 12 at one end near the silicone paddle 8, and the threaded sleeve 13 is threaded onto the outside of the threaded portion 12. When the rod 7 extends out of the limiting sleeve 1 with the silicone paddle 8, the ointment can be evenly applied to the damaged skin through the silicone paddle 8 without wasting the ointment.

[0043] The second connecting component includes a spherical protrusion 10 fixedly disposed on the outer surface of the rod body 7, and the number of spherical protrusions 10 is at least two. The sterile gauze ball 9 is movably wrapped around the outside of the spherical protrusion 10. The spherical protrusion 10 allows the sterile gauze ball 9 to remain on the outer surface of the rod body 7, which has a certain limiting effect on the sterile gauze ball 9, thereby allowing multiple sterile gauze balls 9 to be pre-assembled on the surface of the rod body 7.

[0044] An elliptical cone head 11 is provided at the end of the rod body 7 away from the silicone paddle 8, which makes it easier for sterile gauze balls 9 to be inserted into the rod body 7.

[0045] The sliding component includes a slider 4 fixedly sleeved on the outer surface of the rod 7. The two end faces of the slider 4 are flush with the two end faces of the limiting sleeve 1. The surface of the limiting sleeve 1 has two grooves 2 for sliding of the slider 4, and the grooves 2 are parallel to the rod 7. The outer surface of the slider 4 is fixedly provided with two symmetrically distributed limiting plates 5, and the end face of the two limiting plates 5 away from the rod 7 slides against the inner wall of the limiting sleeve 1. Through the sliding assembly of the slider 4 and the grooves 2, and the limiting effect of the two limiting plates 5, the rod 7 can be stably axially slid inside the limiting sleeve 1.

[0046] Limiting grooves 14 are provided on both ends of the slider 4. The limiting grooves 14 are used to increase the friction between the operator's hand and the surface of the slider 4.

[0047] Each limiting plate 5 is equipped with a set of second magnetic inserts 6 inside, and the upper and lower end faces of the limiting sleeve 1 are equipped with three sets of first magnetic inserts 3. Two sets of first magnetic inserts 3 located on the same side are distributed at the beginning and end of the groove 2, and the other set of first magnetic inserts 3 is distributed between the two sets of first magnetic inserts 3. Each set of first magnetic inserts 3 and second magnetic inserts 6 has four units. The magnetic poles of the opposing end faces of the first magnetic inserts 3 and second magnetic inserts 6 located on the same side are opposite. Through the magnetic attraction limiting treatment of the second magnetic inserts 6 and the three sets of first magnetic inserts 3, the slider 4 can be limited to three positions in the limiting sleeve 1, namely the silicone paddle 8 extended state, the sterile gauze ball 9 extended state, and the silicone paddle 8 and the sterile gauze ball 9 simultaneously retracted into the limiting sleeve 1.

[0048] Example 2: Please refer to Figure 2 This embodiment is a further explanation of Embodiment 1. In the figure, both ends of the limiting sleeve 1 are provided with rounded skirts 22. The rounded skirts 22 are used to separate the skin tissue and the limiting sleeve 1, and the rounded surface is used to avoid skin scratches and pain.

[0049] Example 3: Please refer to Figure 1 , Figure 5 and Figure 6This embodiment is a further explanation of Embodiment 1. In the figure, a protective sleeve 15 is movably sleeved on the outside of the limiting sleeve 1. One end of the protective sleeve 15 is a closed port and the other end is an open port. A sealing cap 18 is provided at the open port of the protective sleeve 15. A silicone gasket 19 is fixedly provided on one end face of the sealing cap 18 near the protective sleeve 15. The silicone gasket 19 is in movable contact with the open port of the protective sleeve 15. A limiting component is provided between the sealing cap 18 and the protective sleeve 15. Under the action of the limiting component, the sealing cap 18 can be tightly closed at the open port of the protective sleeve 15.

[0050] The limiting component includes limiting straight grooves 16 formed on two opposite end faces of the protective sleeve 15. Each limiting straight groove 16 has several ratchet grooves 17 arranged in a straight line at equal intervals inside. The limiting straight grooves 16 are distributed outside the open port of the protective sleeve 15. Two levers 20 are fixedly provided at one end of the sealing cover 18 near the protective sleeve 15, and the levers 20 slide and engage with the limiting straight grooves 16. At least one of the opposing end faces of the two levers 20 is fixedly engaged with the ratchet grooves 17. The ratchet block 23 and the paddle 20 have a raised part 21 on the end face away from the sealing cover 18. The raised part 21 can be used to paddle the paddle 20 to separate the ratchet block 23 from the ratchet groove 17. The silicone gasket 19 has a hollow structure. When the silicone gasket 19 is squeezed, it is easier to undergo elastic deformation, and the resulting reaction elastic force can make the ratchet block 23 and the ratchet groove 17 fit more tightly. The protective sleeve 15, the sealing cover 18 and the paddle 20 are all medical-grade rigid TPU plastic.

[0051] The application principle of this solution is as follows: When applying the medication to the damaged skin, depending on the state of the medication, it can be selectively applied using a silicone paddle 8 or a sterile gauze ball 9. If it is a paste-like medication, the operator can push the rod 7 using the slider 4, so that the silicone paddle 8 can extend out of the limiting sleeve 1. At this time, the second magnetic insert 6 can also be magnetically attracted and limited by a set of first magnetic inserts 3 on the left side, thus making it convenient for the operator to hold the limiting sleeve 1 and apply the paste-like medication using the silicone paddle 8. Applying the paste-like medication using the silicone paddle 8 can effectively avoid the waste of the paste-like medication, and at the same time, it can also evenly apply the paste-like medication to the skin surface.

[0052] If the medication is liquid, the operator pushes slider 4 to the other side, allowing rod 7 to extend sterile gauze ball 9 out of rounded skirt 22. Through the magnetic attraction of the second magnetic insert 6 and a set of first magnetic inserts 3 on the other side, the operator can hold the limiting sleeve 1 and insert the sterile gauze ball 9 into the medication bottle via rod 7. Depending on the size of the wound, the operator can selectively immerse one or more sterile gauze balls 9 simultaneously in the liquid medication. During immersion, rod 7 should be kept vertically inserted into the medication bottle. Then quickly remove the sterile gauze ball 9 from the liquid surface. This dipping method ensures that the medication will not drip from the surface of the sterile gauze ball 9 even when it is not fully saturated with the medication. The medication will only penetrate into the interior of the sterile gauze ball 9, even if it has not been fully absorbed. When the rod 7 carries the sterile gauze ball 9 away from the medicine bottle, there will be no dripping, thus avoiding waste of medication and effectively reducing liquid medication loss. The cooperation between the limiting sleeve 1 and the rod 7 also makes it convenient for operators to apply the sterile gauze ball 9, which has absorbed the medication, to the skin surface.

[0053] In this design, the limiting sleeve 1 is stored inside the protective sleeve 15. Through the sliding assembly of the paddle 20 and the limiting groove 16, the sealing cover 18 can be closed on the end of the protective sleeve 15. During the process of pressing the sealing cover 18 on the end of the protective sleeve 15, the silicone gasket 19 can be squeezed, causing the silicone gasket 19 to undergo elastic deformation. When the ratchet block 23 engages with the ratchet groove 17, the reaction elastic force generated by the silicone gasket 19 can also make the sealing cover 18 and the protective sleeve 15 more tightly connected, while ensuring the sealing between the protective sleeve 15 and the sealing cover 18.

[0054] It should be noted that the portable application device in this solution can be reused multiple times after disinfection. The sterile gauze ball 9 can slide directly off the surface of the rod body 7 to assemble a clean sterile gauze ball 9. Moreover, the sterile gauze ball 9 located at the end of the rod body 7 simultaneously covers the spherical protrusion 10 and the elliptical cone head 11, that is, the end of the elliptical cone head 11 will not be exposed, thus preventing the medicine from dripping down the elliptical cone head 11.
