Description

Technical Field

[0001] This utility model belongs to the field of medical devices and relates to a non-contact ointment application device, particularly to a quantitative ointment delivery 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 quantitative ointment applicator that can be adjusted to suit different ointment dosages, accurately administers the medication, and maintains isolation during application to avoid cross-infection.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A quantitative ointment applicator includes a front and back through outer sleeve, a push rod slidingly inserted inside the outer sleeve, an elastic buckle provided on one side of the rear end of the outer sleeve, a plurality of engaging steps corresponding to the elastic buckle on the rear part of the push rod, and a silicone sleeve fitted on the front end of the push rod.

[0005] This device uses different locking steps at the rear of the push rod and elastic buckles at the rear of the outer sleeve to position different medication dosages. When the elastic buckles engage different locking steps, the medication dosage can be adjusted between 4ml, 8ml, and 12ml (other dosages can also be set according to different specifications). During administration, after determining the dosage adjustment, squeeze the ointment from the front of the outer sleeve, filling the space between the front of the silicone sleeve of the push rod and the inner wall of the outer sleeve. Then, aim at the affected area and push the push rod forward to squeeze the ointment onto the affected area. Afterward, pull the push rod out of the silicone sleeve, using the silicone sleeve to spread the ointment evenly. This device allows for precise dosage control by adjusting the push rod setting. During administration, a very small amount of ointment adheres to the inner wall of the outer sleeve, reducing waste. Finally, the silicone sleeve acts as a barrier to evenly spread the ointment and prevent cross-infection.

[0006] Preferably, a venting gap is provided between the outer wall of the silicone sleeve and the inner wall of the outer sleeve. When the ointment is squeezed in, air can be expelled through the venting gap, preventing air pockets from affecting the dosage. The venting gap can be achieved through a clearance fit between the silicone sleeve and the outer sleeve, or by providing a shallow axial groove on the outer wall of the silicone sleeve or the inner wall of the outer sleeve.

[0007] Preferably, the push rod is a hollow shell, and its front end has a vent hole for easy assembly and disassembly of the silicone sleeve. This vent hole allows the space between the push rod's front end and the silicone sleeve to communicate with the outside, facilitating the assembly and disassembly of the silicone sleeve.

[0008] Preferably, the front end of the push rod is a flat surface or a forward-convex arc surface.

[0009] Preferably, the elastic buckle includes a rotating shaft that is rotatably fixed to the rear end of the outer casing. One side of the rotating shaft is a locking head for attaching to the step hook, and the other side of the rotating shaft is a pressing wrench. An elastic piece for resetting is provided between the inner side of the pressing wrench and the outer wall of the outer casing.

[0010] Preferably, the snap-fit ​​step is an annular protrusion that surrounds the rear of the push rod, with the rear end face of the annular protrusion being the snap-fit ​​plane and the front end face being the guide slope.

[0011] Preferably, the rear end face of the push rod is provided with an annular limiting protrusion.

[0012] This invention allows for the adjustment of the push rod position according to different dosages, enabling quantitative drug administration. During the administration process, a very small amount of ointment adheres to the inner wall of the outer sleeve, reducing waste. Finally, a silicone sleeve is used as an isolation layer to evenly apply the ointment and avoid cross-infection. Attached Figure Description

[0017] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0018] Example: A quantitative ointment applicator, such as... Figure 1 , 2 As shown, it includes a cylindrical outer casing 1 that runs through the entire length of the casing. A push rod 2 slides through the interior of the casing. An elastic buckle 3 is located on one side of the rear end of the outer casing. The rear of the push rod has several engaging steps 8 corresponding to the elastic buckle, with different engaging steps corresponding to different drug dosages. A silicone sleeve 12 is fitted over the front end of the push rod. An venting gap 10 is provided between the outer wall of the silicone sleeve 12 and the inner wall of the outer casing 1. The venting gap 10 can be achieved through a clearance fit between the silicone sleeve and the outer casing, or by creating a shallow axial groove on the outer wall of the silicone sleeve or the inner wall of the outer casing.

[0019] The elastic buckle 3 includes a rotating shaft 4 rotatably fixed to the rear end of the outer casing.
