Description

Technical Field

[0001] The invention relates to the field of medical medicated applicators, and in particular to a skin infection prevention and medication application device. Background Art

[0002] Dermatology departments often prescribe ointments or reagents for application to the skin. Patients with skin diseases require continuous application of these medications to the affected areas during long-term treatment. Proper application technique ensures effective absorption and minimizes side effects. Applying the ointment too thickly can cause the drug to penetrate too deeply into blood vessels, potentially causing systemic side effects. Applying the ointment too thinly can result in superficial penetration, compromising treatment effectiveness.

[0003] Currently, the fingertip unit (FTU) method is often used to control drug dosage. For example, an adult can apply ointment (about 0.5g) on ​​the end of the index finger to the area of ​​2 palms, while children need to use a smaller amount. Controlling the dosage of the drug with the fingertips is not accurate in the drug supply, and it is difficult to ensure uniformity when applying it over a large area. At the same time, when applying the drug with both hands, the ointment is usually sticky and sticky to the hands. If the hand washing and disinfection process is not done properly, it is easy for bacteria to be carried to the ointment or the patient's infected area, affecting the efficacy. Summary of the Invention

[0004] To address the problems of the prior art, the present invention proposes a skin anti-infection medication application device that automatically squeezes out ointment and applies it to the infected area of ​​the patient, reducing the patient's limbs from contact with the ointment, thereby reducing infection. Furthermore, the automatic extrusion of the medication during application improves the uniformity of the medication application.

[0005] To achieve the above object, the present invention adopts the following technical solution: a skin infection prevention and medication device, comprising a housing, a handle on the housing, an opening on the handle, and a driving component rotatably connected to the handle for covering the opening;

[0006] The roller assembly includes a pair of roller frames arranged in parallel, the roller frames are provided with a U-shaped groove for rotatably connecting the smear roller, and the two sides of the U-shaped groove are also relatively slidably connected to the limit rod, and the limit rod is connected to the roller frame through a spring. When the smear roller slides from the end of the U-shaped groove to and contacts the limit rod, the limit rod slides away from the U-shaped groove. When the smear roller slides to the bottom of the U-shaped groove, the limit rod rebounds and engages the smear roller;

[0007] The delivery assembly includes a drug container mounted within a housing and an elastic airbag mounted at the handle position, the drug container and the elastic airbag being connected via a first delivery tube, the elastic airbag being further connected to a second delivery tube, the second delivery tube extending between the applicator rollers; the first delivery tube and the second delivery tube being respectively provided with a first one-way valve and a second one-way valve; the drug container also being provided with a pressure relief hole; when the elastic airbag is compressed or rebounded, the drug in the drug container can be drawn along the first delivery tube and the second delivery tube to the applicator roller;

[0008] An extrusion assembly includes a housing for mounting the elastic airbag, a push plate slidably connected to one side of the elastic airbag in the housing chamber, and the push plate is connected to the handle via a first spring; the push plate can be rotated by the driving component to contact the handle and slide back and forth in the housing chamber;

[0009] A squeeze plate is hingedly connected to one side of the push plate adjacent to the elastic airbag, and a second spring is provided at the end of the squeeze plate near the outlet of the elastic airbag, connected to the push plate. When the push plate drives the squeeze plate to move, the end of the squeeze plate away from the outlet of the elastic airbag first contacts the elastic airbag, and then squeezes along the bottom of the elastic airbag to the outlet, thereby discharging the medium contained in the elastic airbag.

[0010] Furthermore, the outlet end of the elastic airbag is provided with an I-shaped structure, which is detachably engaged with the fracture of the side wall of the accommodating chamber, and is provided with a covering member, which is fixedly connected to the first delivery tube and the second delivery tube, so that the first delivery tube and the second delivery tube are connected to the airbag; the handle is also rotatably connected to a screw, which is threadedly connected to the covering member, and rotating the screw can drive the covering member away from or closer to cover and seal the outlet of the elastic airbag;

[0011] Furthermore, the medicine container is further provided with a medicine replenishing port, and the pressure relief hole is provided at the medicine replenishing port.

[0012] The beneficial effects of the present invention are as follows: When in use, the present invention can be used to press the driving component by holding the handle, causing it to contact the push plate, which further drives the extrusion plate to contact the bottom of the elastic airbag, gradually squeezing the gas inside the elastic airbag from bottom to top and discharging it from the second delivery tube. The ointment follows the gas flow from the drug container into the elastic airbag through the first delivery tube, and then continuously pressing the driving plate causes the drug medium to be discharged from the second delivery tube under the guidance of the one-way valve. The discharged drug is evenly applied to the infected area of ​​the patient by the rolling of the application roller, reducing the contact of the patient's limbs with the ointment application, thereby reducing infection. At the same time, the extruded drug is applied by the application roller, which also improves the uniformity of the drug application. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0021] See Figures 1 to 6 The figure shows a skin infection prevention and medication application device, comprising a cylindrical housing 1 with a handle 101. Handle 101 has an opening 104 oriented toward the axis of housing 1. A driving component 103 is rotatably connected to handle 101 and capable of closing opening 104. Driving component 103 is a cover adapted to the curvature of handle 101. A pressing head 1031 is disposed on driving component 103, facing the interior of handle 101. When driving component 103 rotates to close opening 104, it drives pressing head 1031 to extend toward the interior of handle 101.

[0022] like Figure 3The illustrated medication dispensing device further includes a roller assembly 2, which is disposed at one end of the housing 1. A pair of roller frames 201 are disposed side by side thereon. The roller frames 201 are provided with a U-shaped groove 2011 for rotatably connecting to a smear roller 202. Specifically, a roller shaft 203 of the smear roller 202 can be placed at the bottom of the U-shaped groove 2011, and the roller shaft 203 can be loosely fitted with the U-shaped groove 2011, allowing it to rotate at the bottom of the U-shaped groove 2011. Limiting rods 204 are also slidably connected to each other on both sides of the U-shaped groove 2011. The limiting rods 204 are connected to the roller frame 201 via a spring, and the end of the limiting rod 204 near the U-shaped groove 2011 is V-shaped. During use, when the roller shaft 203 of the smear roller 202 slides from the end of the U-shaped groove 2011 to contact the V-shaped end of the limiting rod 204, it guides the limiting rod 204 away from the U-shaped groove 2011, stretching the limiting spring 205, allowing the limiting rod 204 to release the smear roller 202. When the smear roller 202 slides to the bottom of the U-shaped groove 2011, the limiting rod 204 rebounds and engages the smear roller 202. Because patients are very susceptible to infection when applying medication to their skin, the smear roller 202 can be configured as a disposable item. The roller assembly 2 described above makes it easy to remove and replace the smear roller 202, reducing secondary use and preventing cross-infection. During replacement, when removing or installing the smear roller 202 from the U-shaped groove 2011, the limiting rod 204 can automatically retreat to avoid or rebound to engage the rotating shaft of the smear roller 202, improving removal efficiency.

[0023] like Figure 4 The diagram shows the delivery assembly 3 of the medication application device, which includes a medication container 301 mounted within the housing 1 and an elastic airbag 302 mounted at the handle 101. The medication container 301 and the elastic airbag 302 are connected by a first delivery tube 305. The elastic airbag 302 is also connected to a second delivery tube 306, which extends between the two applicator rollers 202. The first and second delivery tubes 305 and 306 are respectively equipped with a first one-way valve 303 and a second one-way valve 304. The medication container 301 also has a pressure relief hole 308 for balancing the pressure difference between the interior of the medication container 301 and the external environment, facilitating the flow of the medication medium. When the elastic airbag 302 is pressed, the medication medium flowing in the first and second delivery tubes 305 and 306 is directed in a single direction under the guidance of the first and second one-way valves 303 and 304. Therefore, the medicine in the medicine container 301 can be drawn along the first delivery tube 305 and the second delivery tube 306 to between the two application rollers 202 by compression or rebound of the elastic airbag 302. Figure 2The second delivery tube 306 is shown to be spaced a certain distance from the discharge end of the applicator roller 202 to the patient's skin and the outside of the applicator roller 202. This arrangement reduces infection. The applicator roller 202 rolls over the infected area on the patient's outer skin. Holding the handle 101 and pushing the medication dispensing device in either direction causes one of the two applicator rollers 202 to roll and evenly distribute the dispensed medication, thereby improving the uniformity of medication application.

[0024] like Figure 5 The extrusion assembly 4 of the medication dispensing device is shown. It includes a housing 401 for mounting the elastic airbag 302. A push plate 402 is slidably connected to one side of the elastic airbag 302 within the housing 401. The push plate 402 is connected to the handle 101 via a first spring 404, allowing the push plate 402 to reset as it moves within the housing 401. The push plate 402 can be rotated into contact with the drive component 103, specifically, through the pressing head 1031 of the drive component 103, and can slide back and forth within the housing 401.

[0025] A squeeze plate 403 is hingedly connected to the side of the push plate 402 adjacent to the elastic airbag 302. A support rod 4021 is provided on the push plate 402, forming a T-shaped structure. The squeeze plate 403 is hinged to the top of the support rod 4021. The end of the squeeze plate 403 closest to the outlet of the elastic airbag 302 is also provided with a second spring 405 connected to the push plate 402. When the push plate 402 drives the squeeze plate 403 to move, the end of the squeeze plate 403 farther from the outlet of the elastic airbag 302 first contacts and squeezes the elastic airbag 302, causing the bottom of the elastic airbag 302 to contact the sidewall of the receiving chamber 401. Guided by the sidewall of the receiving chamber 401, the squeeze plate 403 rotates along the tip of the support rod 4021, stretching the second spring 405 and squeezing the liquid along the bottom of the elastic airbag 302 to the outlet, thereby expelling the drug medium contained in the elastic airbag 302. This arrangement can preferentially squeeze the drug medium at the bottom of the elastic airbag 302, reduce the pressure on the elastic airbag 302, and increase the service life of the elastic airbag 302. At the same time, it can also increase the discharge volume of the drug medium inside the elastic airbag 302, avoiding residual drug medium inside the elastic airbag 302.

[0026] The outlet of the elastic airbag 302 is an I-shaped structure that removably snaps onto the break 406 in the sidewall of the accommodating chamber 401. A cover 502 is also provided on the cover. The cover 502 has a conical, concave structure and a sealing ring installed within it, corresponding to the conical structure of the outlet of the elastic airbag 302. The cover 502 is fixedly connected to the first and second delivery tubes 305, 306, connecting the first and second delivery tubes 305, 306 to the airbag. A screw 501 is also rotatably connected to the handle 101. The lower end of the screw 501 extends beyond the lower end of the handle 101 and is threadedly connected to the cover 502. Rotating the screw 501 drives the cover 502 away from or toward the outlet of the elastic airbag 302. With this arrangement, the cover 102 at the handle 101 can be opened, and the screw 501 can be rotated to drive the cover 502 away from the outlet end of the elastic airbag 302, making it easy to remove and replace the elastic airbag 302. Of course, to improve the mobility of the cover 502, the first delivery tube 305 and the second delivery tube 306 are made of a flexible material, such as a plastic hose.

[0027] like Figure 4 The illustrated drug container 301 also has a drug refill port 307, and a pressure relief hole 308 is disposed at the drug refill port 307. To ensure airtightness within the drug container 301, in some preferred embodiments, a threaded cap is provided to cover the pressure relief hole 308. Only during use is the threaded cap removed, exposing the pressure relief hole 308 to balance the pressure inside the drug container 301 with the external environment, thereby facilitating the flow of the drug medium within the delivery assembly 3.

[0028] When in use, the present invention places the medication applicator so that the axis of the housing 1 is perpendicular to the patient's infected area, and the applicator roller 202 contacts the affected area. By gripping the handle 101 and pressing the drive component 103, the drive component 103 contacts the push plate 402, which further drives the extrusion plate 403 to contact the bottom of the elastic airbag 302, gradually squeezing the gas inside the elastic airbag 302 from bottom to top and discharging it from the second delivery tube 306. The ointment agent flows from the medication container 301 into the elastic airbag 302 along with the gas through the first delivery tube 305. Continuous reciprocating pressure on the drive plate causes the agent medium to be discharged from the second delivery tube 306 under the guidance of the one-way valve. The expelled agent is evenly applied to the patient's infected area by the rolling of the applicator roller 202, reducing the patient's limbs from contacting the ointment application. The agent medium discharge end maintains a distance from the patient's infected area, thereby reducing infection. Simultaneously, the extruded drug is applied by the applicator roller 202, also improving the uniformity of the drug application.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
