Description

Technical Field

[0001] This utility model belongs to the field of medical devices and relates to a non-contact ointment application device, and in particular to a multi-level ointment administration and application device. Background Technology

[0002] Some patients with skin diseases need to apply ointments to their affected areas regularly. During application, they must follow the doctor's prescription, applying the ointment in the prescribed amount evenly, and avoiding cross-infection. Currently, the most common method of applying ointments is to squeeze the ointment onto the affected area and then spread it with a cotton swab. Some patients find this method inconvenient and sometimes apply it directly with their fingers. Therefore, existing methods of ointment application not only make it difficult to ensure accurate dosage, but cotton swabs also tend to absorb some of the ointment, and applying with hands is unhygienic. Utility Model Content

[0003] The purpose of this invention is to solve the problems of unstable dosage control, uneven application, and lack of hygiene in existing ointment application methods. It provides a multi-level ointment application device that, based on the telescopic principle of a press-and-retract ballpoint pen, has multiple levels corresponding to different ointment dosages. A push-out stop is set between adjacent levels, and a silicone stop at the front end of the push rod is used as the application tool. This allows for targeted and quantitative drug delivery, avoiding direct contact.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a multi-level ointment application device, including an outer casing, a push rod slidably disposed inside the outer casing, a rotating head disposed at the rear end of the push rod, a pressing head disposed at the rear end of the rotating head, and axial guide grooves uniformly disposed around the inner wall of the rear end of the outer casing. Each guide groove is provided with a limiting block to restrict the retraction distance of the rotating head. The guide grooves are sequentially arranged along the circumferential direction as a first-level groove, a ejection groove, a second-level groove, an ejection groove...N-level grooves, and an ejection groove; the depth of the limiting blocks of the first-level groove, the second-level groove...N-level grooves, and the ejection groove decreases sequentially.

[0005] This device adopts the telescopic principle of a press-and-retract ballpoint pen. When the pressing head pushes the rotating head away from the guide groove, the rotating head rotates half the width of the guide groove. When the pressing head retracts, the rotating head is pushed by the end face of the guide groove and rotates another half the width of the guide groove. This allows the rotating head to move one guide groove position in a fixed direction with each press. When the rotating head rotates through the first, second, ... Nth level grooves, it is restricted by the different depths of the limiting blocks. The depth of the push rod is also different. The front end of the push rod and the inner wall of the outer sleeve form a quantitative drug delivery space. Different dosage scale values ​​can be marked on the front end of the outer sleeve. The front end of the outer sleeve can be made of transparent material, allowing real-time observation of the dosage level. Push-out grooves are set between each pair of the first, second, ... Nth level grooves. In use, first adjust the device to the desired medication level by repeatedly pressing the press head. Then, squeeze the ointment into the space at the front of the outer casing. Press the press head again to retract the push rod and squeeze the ointment onto the affected area. When you release the press head, the rotating block will be in the ejector slot position, and the push rod will remain extended, serving as a tool for applying the ointment. After medication administration, clean the push rod and outer casing. Replace the silicone stopper if necessary.

Nth gear slide groove, the front end of the push rod is retracted into the inner side of the outer sleeve at different depths; when the rotating head is engaged in the ejection slide groove, the front end of the push rod extends out of the front end of the outer sleeve.

[0009] Preferably, a first spring is provided between the middle of the push rod and the front end of the outer sleeve.

[0010] Preferably, a second spring is provided between the rear end of the rotating head and the pressing head.

[0011] Preferably, the outer cover includes a detachable front cover and a rear cover, which are connected by threads.

[0012] Preferably, the pressing head is a shell-shaped structure with an open front end, the front side of the pressing head is toothed, the rear end of the rotating head is embedded inside the pressing head, the side of the rotating head is provided with a guide strip, the rear end of the guide strip is provided with a first guide slope that matches the toothed edge of the pressing head, and the front end of the guide groove is provided with a second guide slope that matches the first guide slope.

[0013] Preferably, the first-stage slide, the ejection slide, the second-stage slide, the ejection slide...N-stage slide, and the ejection slide are arranged in two sets symmetrically around the circumference, and guide strips are respectively provided on both sides of the rotating head.

[0014] Preferably, the pressing head is provided with guide blocks that slide along the guide groove evenly around its circumference.

[0015] Preferably, the sum of the thicknesses of the guide block and the limiting block does not exceed the thickness of the guide groove, while the sum of the thicknesses of the guide strip and the limiting block is greater than the thickness of the guide groove. The guide block and the limiting block do not interfere with each other, and the limiting block can restrict the retraction position of the guide strip.

[0016] This invention references the telescopic principle of a press-and-retract ballpoint pen, setting different levels so that the push rod can be at different telescopic lengths, thereby forming different quantitative drug administration levels. A push-out position is set between different drug administration levels, so that the extended push rod can be used as an application tool after one dose is administered, avoiding direct contact.
