Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

The embodiment of the invention comprises the following steps: as shown in fig. 1-5, an auxiliary applicator for oral cavity comprises a housing 1 and a push rod 2, wherein the housing 1 is a circular tube structure, the push rod 2 is connected with one end of the housing 1 in an inserting manner, the outer diameter of the push rod 2 is equal to the inner diameter of the housing 1, an applicator cover body 3 is formed at the other end of the housing 1, a plurality of applicator holes 4 are uniformly distributed on the applicator cover body 3, and an applicator tip 5 matched with the applicator cover body 3 is fixedly arranged at one end of the push rod 2 inserted into the housing 1.

When the medicine applying cover is used, firstly the medicine applying end 5 is adhered with a proper amount of ointment according to the requirement, then one end with the medicine applying end 5 is inserted into the shell 1, preferably, the medicine applying cover is not required to be inserted to the bottom once, a certain space is reserved, then the shell 1 is held by hand, the medicine applying cover body 3 is propped against the position of the dental ulcer, and the medicine applying cover body 3 is preferably made of latex materials or food-grade soft plastics materials in order to improve the use comfort. After the position is found, the push rod 2 is pressed forcefully to enable the medicine dipping end 5 to be tightly abutted to the medicine coating cover body 3, and the ointment on the surface of the medicine dipping end 5 is extruded from the medicine outlet hole 4 and coated on the affected part.

In a preferred embodiment, the housing 1 is provided with an auxiliary push plate 6 at an end thereof remote from the applicator housing 3. The auxiliary push plate 6 extrudes the push rod 2 at last, so that the hands of the patient can be better stressed, and the operation by one hand is convenient.

Further, the medicine applying cover body 3 is of a hemispherical structure, the medicine dipping end 5 is also of a hemispherical structure, the outer diameter of the medicine dipping end 5 is smaller than or equal to the inner diameter of the medicine applying cover body 3, in the embodiment, the outer diameter of the medicine dipping end 5 is preferably designed to be as large as the inner diameter of the medicine applying cover body 3, and therefore the ointment can be extruded more fully.

Because the medicine dipping end 5 adopts a hemispherical structure, if the surface of the medicine dipping end is too smooth, the medicine dipping effect is affected, and the quantity of ointment is not easy to control, a plurality of bristles 16 are preferably arranged on the outer wall of the medicine dipping end 5. The brush hair 16 is soft hair, which not only facilitates the sticking of the ointment, but also can ensure that the ointment is fully extruded by extrusion.

In another preferred embodiment, a first annular limiting groove 7 and a second annular limiting groove 8 are formed on the inner wall of the shell 1 close to the medicine applying cover body 3, the second annular limiting groove 8 is positioned at one side close to the medicine applying cover body 3, the distance from the groove wall of the first annular limiting groove 7 to the axis of the shell 1 is greater than that from the groove wall of the second annular groove 8 to the axis of the shell 1, and a first limiting convex ring 9 matched with the first annular limiting groove 7 and a second limiting convex ring 10 matched with the second annular limiting groove 8 are arranged on the outer wall of the push rod 2.

The first limiting convex ring 9 and the second limiting convex ring 10 are made of rubber materials. Of course, other soft materials can be adopted, and through the design of the structure, when the first limiting convex ring 9 and the second limiting convex ring 10 are respectively clamped into the first annular limiting groove 7 and the second annular limiting groove 8, a gap is formed between the outer wall of the medicine dipping end 5 and the inner wall of the medicine coating cover body 3.

The design purpose of this structure is to prevent patient's maloperation, if once only push rod 2 pushes away to the end then the ointment is directly extruded, causes the waste, and has increased first spacing bulge loop 9 and the spacing bulge loop 10 of second, can be effectively spacing, again because first spacing bulge loop 9 and the spacing bulge loop 10 of second adopt rubber material, need press push rod 2 with great strength and just can extrude the ointment. For convenience of operation, the positions of the first annular limiting groove 7 and the second annular limiting groove 8 are preferably designed to be made of rubber materials or other soft materials.

Further preferably, the push rod 2 is located the outer one end tip of casing 1 and is formed with screw hole 11, is formed with air flue 12 in the push rod 2, and the one end and the screw hole 11 intercommunication of air flue 12, the top of being stained with medicine end 5 is located to the other end of air flue 12, still includes rubber gasbag 13, is provided with the spliced pole 14 of outband screw thread on the rubber gasbag 13, and rubber gasbag 13 passes through spliced pole 14 and the screw hole 11 spiro union. The position of the medicine-coating cover body 3 opposite to the air outlet end of the air channel 12 is provided with an air blowing hole 15.

Through the setting of rubber gasbag 13 and air flue 12, can realize the operation of drying by blowing dry to canker sore earlier through extrusion rubber gasbag 13 before scribbling the medicine, prevent that the ointment from scribbling the back and coming off soon to strengthen treatment. The first limiting convex ring 9 and the second limiting convex ring 10 are matched, so that the phenomenon that ointment is extruded due to misoperation is avoided when the drying operation is carried out.

In another preferred embodiment, the inner wall of the medicine-applying cover body 3 is formed with a connecting pipe 17 communicated with the air blowing hole 15, the air outlet end of the upper air passage 12 of the medicine wetting end 5 is formed with a connecting hole 18, the connecting hole 18 is arranged opposite to the connecting pipe 17, the connecting pipe 17 is connected with the connecting hole 18 in an inserting way, the outer diameter of the connecting pipe 17 is equal to the diameter of the connecting hole 18, and the length of the connecting hole 18 is larger than that of the connecting pipe 17.

Specifically, the air blowing hole 15, the connecting pipe 17, the air channel 12 and the connecting hole 18 are coaxially arranged, air is blown through the rubber air bag 13 during use, the position of the dental ulcer is dried, ointment is easily blown out directly if the connecting pipe 17 is not arranged, the connecting pipe 17 is arranged, when the first limiting convex ring 9 and the second limiting convex ring 10 are clamped into the first annular limiting groove 7 and the second annular limiting groove 8 respectively, the connecting pipe 17 is also inserted into the connecting hole 18, and therefore air blown out through the rubber air bag 13 is directly blown out through the air blowing hole 15 without blowing out the ointment together, and user experience is improved. For the ointment entering the connecting hole 18 when the medicine dipping end 5 is dipped in the medicine, the ointment in the connecting hole 18 can be extruded out by pressing the rubber air bag 13 once after the push rod 2 is installed in place, and then the ointment is normally used.

The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
