Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, and particularly relates to an oral speculum protective cap. Background Art

[0002] When performing oropharyngeal surgery in otolaryngology department, an oral speculum is needed to assist the surgery. Currently, the oral speculum used clinically is the Davis oral speculum. As shown in the attached drawings Figure 1 The Davis oral speculum includes a tooth fixing hook 01 for fixing teeth and a tongue depressor 02 for pressing down the tongue. The tooth fixing hook and the tongue depressor are connected by a U-shaped connecting frame 03 and a sliding sleeve 04. When in use, the tooth fixing hook and the tongue depressor cooperate to assist the patient to open the mouth.

[0003] However, in actual use, since both the tooth fixing hook and the tongue depressor are made of metal materials and are relatively hard, they are likely to damage the teeth and the tongue. To solve this problem, doctors will pad gauze blocks on the tooth fixing hook and the tongue depressor for protection. However, the gauze is prone to displacement during use, and the fixing effect is poor, thus resulting in a poor protection effect on the teeth and the tongue. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an oral speculum protective cap to solve the technical problem that the oral speculum in the prior art is likely to damage the teeth and the tongue.

[0005] To solve the above technical problem, the utility model specifically provides the following technical solutions:

[0006] An oral speculum protective cap includes a cap body. The cap body is a bag-shaped structure with one end open and flat. The open end of the cap body is set as the opening end. Two hanging ears are fixedly connected to the opening end. A plurality of convex strips parallel to the opening end are fixedly connected to both sides of the inner wall of the cap body. The cross-section of the convex strip is triangular.

[0007] The cap body is made of an elastic material, and a plurality of air bubbles are arranged inside the side wall of the cap body.

[0008] As a preferred scheme of the utility model, the side of the convex strip close to the opening end is set as an inclined surface inclined in the direction away from the opening end.

[0009] As a preferred scheme of the utility model, the diameter of the air bubble is 1-3 millimeters.

[0010] As a preferred scheme of the utility model, an anti-slip strip is arranged on one side of the outer surface of the cap body. The cross-section of the anti-slip strip is trapezoidal.

[0011] The utility model has the following beneficial effects compared with the prior art:

[0012] The utility model makes the cap body closely fit with the fixed tooth hook and the tongue depressor on the mouth opener by providing an elastic flat cap body and a convex strip with a triangular cross-section. The design of the triangular convex strip makes the cap body easy to put on but not easy to take off, so that the protective cap is not easy to shift, and at the same time has a good protective effect on the teeth and tongue.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] As Figure 2 shown, the present invention provides a protective cap for a mouth opener, which mainly protects the fixed tooth hook and the tongue depressor through the convex strip 40 and the cap body 10.

[0023] The mouth gag protector cap includes a cap body 10, the cap body 10 is a bag-shaped structure with a flat shape and an open end, the open end of the cap body 10 is set as an open end 30, and two hanging ears 20 are fixedly connected to the open end 30. On both sides of the inner wall of the cap body 10, a plurality of rib strips 40 parallel to the open end 30 are fixedly connected, and the cross-section of the rib strip 40 is triangular;

[0024] The cap body 10 is made of an elastic material, and a plurality of air bubbles 11 are arranged inside the side wall of the cap body 10.

[0025] In actual use, since both the tooth fixing hook and the tongue depressor are made of metal materials and are relatively hard, they are likely to damage the teeth and tongue. To solve this problem, doctors will pad gauze blocks on the tooth fixing hook and the tongue depressor for protection. However, the gauze is prone to displacement during use, and the fixing effect is poor, which in turn makes the protection effect on the teeth and tongue also poor. Therefore, it is necessary to develop an oral opener protection device that is not easy to damage the teeth and tongue.

[0026] In this embodiment, by providing an elastic flat cap body 10 and rib strips 40 with a triangular cross-section, the cap body 10 is closely attached to the tooth fixing hook and the tongue depressor on the oral opener. The design of the triangular rib strips 40 makes the cap body 10 easy to put on but not easy to take off, making the protection cap not easy to displace, and at the same time having a good protective effect on the teeth and tongue.

[0027] In actual use, 1. The cap body 10 has various sizes, and a suitable size is selected according to the part to be sleeved;

[0028] 2. Pinch the two hanging ears 20 with fingers and pull the hanging ears 20 towards both sides of the cap body 10, so that the open end 30 of the cap body 10 deforms. Then, sleeve the cap body 10 on the tooth fixing hook or the tongue depressor, and then release the pulling of the hanging ears 20;

[0029] 3. Due to the design of the rib strips 40, the friction between the cap body 10 and the tooth fixing hook or the tongue depressor is increased, preventing the cap body 10 from slipping off;

[0030] 4. Since the cap body 10 is made of an elastic material, the cap body 10 can deform. During use, due to the existence of the air bubbles 11 inside the side wall of the cap body 10, the elasticity of the cap body 10 is increased, and it can better protect the teeth and tongue.

[0031] As a preferred embodiment of this embodiment, as Figure 2 shown, the side of the rib strip 40 close to the open end 30 is set as an inclined surface 41 inclined in a direction away from the open end 30. This makes it easier to sleeve the cap body 10, and the cap body 10 is not easy to fall off, improving the firmness of the connection between the cap body 10 and the tooth fixing hook or the tongue depressor.

[0032] Furthermore, the diameter of the bubble 11 is 1-3 mm. By providing the bubble 11, when the fixed tooth hook or the tongue depressor squeezes the teeth or the tongue, the extrusion force can be buffered, increasing the protection effect.

[0033] On the basis of increasing the connection firmness between the cap body 10 and the fixed tooth hook or the tongue depressor, the stability between the cap body 10 and the teeth or the tongue is also very important to improve the stability of the mouth opener. Specifically, an anti-slip strip 12 is provided on one side of the outer surface of the cap body 10, and the vertical cross-section of the anti-slip strip 12 is trapezoidal. By providing the anti-slip strip 12, the friction between the outer side of the cap body 10 and the teeth or the tongue is increased. At the same time, the gap between the anti-slip strips 12 can catch the teeth, increasing the stability of the mouth opener.

[0034] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
