Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel oral care cotton swab. Background Technology

[0002] Currently used oral care tools in clinical practice have the following main problems: most oral care tweezers are straight and rigid, unable to bend, making it difficult to reach deep into the corners of the mouth (such as between teeth and the lateral walls of the throat); at the same time, the operator's hands can block light during operation, affecting the observation of the cleaning location; the traditional method of using tweezers to pick up cotton balls is prone to loosening and falling off, posing a safety hazard; existing disposable care tweezers are mostly of a one-piece structure, and even if the tweezer is intact, it must be discarded as a whole after cleaning the head, making it impossible to reuse the tweezer for the same patient, resulting in resource waste. Utility Model Content

[0003] To address the aforementioned technical problems, a novel oral care cotton swab is provided. The technical means employed in this invention are as follows: A novel oral care cotton swab, characterized in that it comprises: a rod body, a bendable portion, a detachable cotton head, and a support rod, one end of which is fixedly connected to the front end of the rod body, the bendable portion is sleeved on the outside of the support rod, the bendable portion is a corrugated tube structure, and the support rod is a shape memory metal wire or a shape-measuring metal wire, and the bendable portion is driven and maintained by bending the support rod. The cotton head includes a supporting wooden stick, one end of which is fixed with a medical degreased cotton ball. The other end of the supporting rod is integral with the supporting wooden stick. Alternatively, the other end of the supporting wooden stick is provided with a connecting part, and the other end of the supporting rod is fixedly connected with a metal connector.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1 This invention provides a novel oral care swab, comprising a shaft 1, a bendable portion 2, and a detachable cotton head 3. The bendable portion 2 is located at the front end of the shaft 1, and has a deformable support rod 4 inside. Both ends of the support rod 4 are connected to the support structure (a supporting wooden stick 5) of the shaft 1 and the cotton head 3, respectively. The shape of the bendable portion 2 is driven and maintained by bending the support rod 4. The support rod 4 does not deform on its own; during use, the bending angle of the support rod 4 is manually adjusted according to actual usage needs (such as the position in the mouth).

[0025] The bendable part 2 has a corrugated tube structure with protrusions on its inner wall to increase locking friction. The support rod 4 is made of shape memory metal wire or shapeable metal wire, and is covered with a medical-grade flexible insulating coating. A medical degreased cotton ball is fixed to one end of the support structure, and a connecting part 6 is provided at the other end. The support rod 4 and the connecting part 6 are an integral structure, or the support rod 4 and the connecting part 6 are detachably connected by threads. The support rod 4 and the connecting part 6 can also be detachably connected by a buckle, which can adopt an existing structural form. The cross-section of the support rod 4 is circular or elliptical. The material of the bendable part 2 is medical-grade thermoplastic elastomer or modified engineering plastic (existing materials). The surface of the rod body 1 is provided with an anti-slip grip area 7, which is a textured surface or a silicone coating.

[0026] The angle of the cotton head can be adjusted and stabilized by bending the built-in support rod, making it easy to clean complex areas of the oral cavity. The corrugated structure of the bendable part works in conjunction with the internal support rod to provide an angle locking mechanism of "coarse adjustment + fine adjustment", which enhances the stability and reliability of use. The cotton head is detachable, so the rod (including the bendable part) can be reused by the same patient after disinfection, and only the cotton head needs to be replaced, saving resources.

[0027] Example 2 The rod 1 is injection molded from medical-grade polypropylene (PP, an existing material), with a length of 10cm and a diameter of 3mm. The tail end is molded with anti-slip textures as an anti-slip grip area 7. The bendable part 2 is a corrugated tube structure made of medical-grade thermoplastic polyurethane (TPU), with a wall thickness of approximately 0.5mm and evenly distributed hemispherical protrusions on the inner wall. The deformable support rod 4 is made of 0.8mm diameter shape memory alloy (nickel-titanium alloy) wire, coated with a food-grade silicone coating. One end of the support rod 4 is fixed to the cavity at the front end of the rod 1 using medical epoxy adhesive.

[0028] One end of the support rod 5 of the cotton head 3 is fixed to a medical absorbent cotton ball by heat pressing, and the other end is machined with a micro external thread of M2 as a connecting part 6. The free end of the support rod 4 is passed through the corrugated tube (i.e., the bendable part 2), and then fixed to a prefabricated metal connector with epoxy resin. The metal connector is embedded in a plastic joint, which is fixed to the front end of the bendable part 2 by heat fusion. In use, the external thread on the support rod 5 of the cotton head 3 is screwed into the internal thread of the plastic joint to complete the assembly.

[0029] During the procedure, medical staff manually bend the corrugated tube according to the areas of the patient's mouth that need cleaning. The internal shape memory alloy support rod 4 deforms accordingly and remains at the new angle. After applying an appropriate amount of warm water or mouthwash, the cleaning can be performed. After use, the cotton head 3 can be discarded by rotating it counterclockwise. The rod body can be thoroughly wiped with 75% alcohol (especially the flexible parts), or soaked in medical disinfectant for 10-15 minutes. After drying, a new sterile cotton head 3 can be replaced for the next treatment.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
