Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a skin medicine applicator. Background Art

[0002] The largest organ in the human body is the skin, which accounts for 5% to 15% of the total weight and covers an area of ​​about 1.5 to 2 square meters. Depending on individual differences and location, its thickness may be between 0.5 and 4 mm. The skin is spread all over the body, protecting the internal tissues and organs and resisting various external insults, such as physical, mechanical, chemical, and pathogenic microorganisms. Therefore, dermatology mainly studies and treats various skin problems. When people suffer from skin diseases, local fungal infections often occur. If the infected area is not resolved in time during surgery or treatment recovery, it may lead to systemic infection. Therefore, in daily care, we need to clean the infected area frequently.

[0003] Among the majority of elderly patients in dermatology, many middle-aged and elderly people have gradually reduced immunity due to their aging, and shingles have become a frequent visitor to dermatology. Patients with this disease need to apply medicine to the affected area almost every day, but in real life, patients almost always go home and apply the medicine by themselves after getting the medicine in the hospital. Most of them use cotton swabs to dip the medicine and apply it to the affected area. However, after using the medicine, most patients will dip the used cotton swabs into the medicine again. After application, the medicine at the medicine outlet will generally flow back into the medicine container as the force of squeezing the medicine disappears. At the same time, bacteria will also enter the container and contaminate the entire medicine, which can easily lead to secondary contamination when applying next time. In addition, the hands can easily come into contact with the medicine during the whole process, resulting in drug contamination, affecting the subsequent treatment cycle.

[0004] Chinese patent number: CN209451134U, discloses a skin medicine coating device, including a medicine storage bottle, a medicine guide tube and a medicine coating rod, the medicine storage bottle and the medicine coating rod are connected to the medicine inlet and outlet of the medicine guide tube respectively, the tube wall of the medicine guide tube is provided with a protrusion and a slide switch, a support rod is provided inside the medicine guide tube, the support rod includes a slider, a support block, a blocking block and a spring, the blocking block can block the medicine outlet of the medicine guide tube, when the slide switch pushes the support rod, under the action of the spring, due to the cooperation of the slider and the protrusion, the blocking block can block or open the medicine outlet, when the medicine outlet is opened, the medicine liquid can flow into the medicine coating rod with a plurality of fine holes. The above-mentioned skin medicine coating device can avoid some drug contamination or cross infection caused by traditional hand or cotton swab application, and different patients are equipped with special medicine coating rods, the use of medicine is hygienic and safe, and it is easy to disassemble and clean after use. However, in actual use in life, since a large part of skin disease drugs are ointment-type jelly-type, it is very likely that the ointment cannot be squeezed out normally in the device when using the drug applicator in the application, and the ointment is also very likely to be blocked and sticky in the drug applicator, so the device is still inconvenient to use when using ointment-type skin disease drugs. At the same time, when the device needs to be cleaned for a second use after use, it is also easy to be not cleaned thoroughly due to the complex internal structure of the device.
