Description

Technical Field

[0001] This utility model relates to the field of daily necessities, and more particularly to medical devices, specifically an improved medicine application brush stick. Background Technology

[0002] In dental procedures, small cotton swabs are commonly used to apply materials or medications, such as for bonding crowns during denture restorations, applying adhesives during resin fillings, and applying desensitizing agents to patients with sensitive teeth. Current technology only uses unidirectional application brushes, which require manual bending and adjustment of the head and tail angles each time they are used to facilitate subsequent procedures. However, this manual bending method results in inconsistent angles after each bend, often necessitating multiple adjustments to suit the specific needs. Utility Model Content

[0003] The purpose of this invention is to provide an improved medicine application brush stick, which solves the technical problem that the bending angle of the brush stick cannot be precisely controlled manually in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An improved application brush stick includes a hollow rod and a hollow cone. The cone is positioned above the rod. The top end of the rod and the bottom end of the cone are connected by a flexible connecting ring. The flexible connecting ring is concave in the circumferential direction. The inner cavities of the rod and the cone are connected by the flexible connecting ring. A spherical bristle is provided at the top of the cone, and an annular moisture-proof cotton is provided below the bristle. A sliding groove is provided on the side wall of the rod, and the sliding groove is provided along the length of the rod. A slider is provided in the sliding groove, and the sliding groove and the sliding groove form a sliding pair. One side of the slider extends into the inner cavity of the rod. A filamentous first connector is provided in the inner cavity of the rod. The upper end of the first connector is connected to the top end of the inner cavity of the cone, and the lower end of the first connector is connected to the inner side of the slider.

[0006] Furthermore, a filamentous second connector is provided in the inner cavity of the rod. The upper end of the second connector is connected to the top end of the inner cavity of the cone, and the lower end of the second connector is connected to the bottom surface of the inner cavity of the rod.

[0007] Furthermore, the side of the groove is provided with graduations.

[0008] Furthermore, a support piece is provided on the side of the moisture-proof cotton facing the rod.

[0009] Working principle:

[0010] This device uses a wire-like connector between a rod and a cone. A slider pulls the connector down to the top of the cone, causing the rod and cone to bend. The slider slides within the groove, making the bending angle controllable within a preset range.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the bending angle of the cone and the rod can be controlled, which facilitates operation by medical staff, improves operation efficiency, and at the same time plays a role in moisture isolation.

[0016] Example 1

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution:

[0018] An improved application brush stick includes a hollow rod 1 and a hollow cone 2. The cone 2 is positioned above the rod 1. The top end of the rod 1 and the bottom end of the cone 2 are connected by a flexible connecting ring 3. The flexible connecting ring 3 is concave in the circumferential direction. The inner cavity of the rod 1 and the inner cavity of the cone 2 are connected by the flexible connecting ring 3. A spherical bristle 4 is provided at the top of the cone 2. An annular moisture-proof cotton 5 is provided below the bristle 4. A groove 6 is provided on the side wall of the rod 1. The groove 6 is arranged along the length of the rod 1. A slider 7 is provided in the groove 6. The groove 6 and the groove 7 form a sliding pair. One side of the slider 7 extends into the inner cavity of the rod 1. A filamentous first connector 8 is provided in the inner cavity of the rod 1. The upper end of the first connector 8 is connected to the top end of the inner cavity of the cone 2, and the lower end of the first connector 8 is connected to the inner side of the slider 7.

[0019] Furthermore, a filamentous second connector 9 is provided in the inner cavity of the rod 1. The upper end of the second connector 9 is connected to the top of the inner cavity of the cone 2, and the lower end of the second connector 9 is connected to the bottom surface of the inner cavity of the rod 1.

[0020] Furthermore, the side of the slide 6 is provided with a scale.

[0021] Furthermore, a support plate is provided on the side of the moisture-proof cotton 5 facing the rod.

[0022] Work process:

[0023] Specifically, the first connector 8 and the second connector 9 can be steel wires.

[0024] The scale on the side of the slide 6 makes it easy to preset the bending angle. The user pulls down the slider 7 according to the scale, and the first connecting piece 8 pulls the top of the cone 2 down, and the cone 2 and the rod 1 bend at the flexible connecting ring 3.

[0025] The flexible connecting ring 3 can deform without breaking.

[0026] The second connector 9 is used to improve the stability of bending.

[0027] The moisture-proof cotton 5 is used to isolate the patient's oral cavity from moisture and saliva, preventing moisture and saliva from affecting the medication on the brush bristles 4.

[0028] The section connected to the bristles 4 is made of a cone shape, which makes it easy to insert into the patient's mouth for operation.
