Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a nasal hemostatic sponge. Background Technology

[0002] Nasal sponges are typically long, flat, or cylindrical. When the nose bleeds, the sponge is inserted into the nasal cavity through the nostril to absorb the blood. Because the sponge expands after absorbing blood, its diameter is usually smaller than the opening of the nostril. During insertion, the sponge is secured within the nasal cavity by the pressure of the nasal tissue at its tip. However, this fixation is limited, and there is a risk of the sponge falling out due to loosening of the fixation, affecting the user experience. Furthermore, because the sponge blocks the nostril, even though it uses a porous, sponge-like material, it can still somewhat impede the smoothness of nasal breathing. Utility Model Content

[0003] The purpose of this invention is to provide a nasal hemostatic sponge that can reduce discomfort during use and improve the fixation strength of the hemostatic sponge in the nasal cavity, thereby reducing the risk of the hemostatic sponge falling out of the nasal cavity.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A nasal cavity hemostatic sponge includes a main body made of sponge material. The main body is cylindrical and has a vent hole extending through it along the axial direction. The upper end of the main body is frustum-shaped and has several protrusions on its side.

[0006] As a further improvement to the above technical solution, each of the protrusions is arranged in a dot matrix pattern on the side of the main body.

[0007] As a further improvement to the above technical solution, a circular flow-limiting strip is provided at the connection between the upper and lower ends of the main body.

[0008] As a further improvement to the above technical solution, the vent hole is provided with several grooves, which are circular and arranged at equal intervals along the axial direction of the main body.

[0009] As a further improvement to the above technical solution, the vent hole is provided with several protrusions, which are circular and arranged at equal intervals along the axial direction of the main body.

[0010] As a further improvement to the above technical solution, the lower end of the main body has two opposite positions with cut surface structures.

[0011] As a further improvement to the above technical solution, a pull wire groove is provided at the lower end of the main body along the circumference of the main body, and a pull wire is wound in the pull wire groove.

[0012] As a further improvement to the above technical solution, the upper edges of both the main body and the vent are provided with a chamfered structure.

[0013] As a further improvement to the above technical solution, the vent hole is cylindrical.

[0014] Compared with the prior art, this utility model has the following advantages and effects:

[0015] This invention, through the design of ventilation holes on the main body, ensures both the hemostatic effect of the main body and the smoothness of nasal breathing, reducing discomfort when using the hemostatic sponge. At the same time, due to the protrusion on the upper end of the main body, the friction between the upper end of the main body and the nasal cavity tissue is increased when the upper end of the main body enters and contacts the tissue, thereby ensuring the compression and fixation strength between the two, reducing the risk of the main body falling out of the nasal cavity, and ensuring the effectiveness and stability of the hemostatic sponge.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0022] Example 1.

[0023] See Figure 1 , Figure 2This embodiment provides a nasal hemostatic sponge, comprising a main body 1. The main body 1 is made of sponge material and is cylindrical with a cylindrical air hole 11 extending through it along the axial direction. This ensures unobstructed breathing while reducing the processing difficulty of the air hole 11 on the main body 1. The upper end of the main body 1 is frustum-shaped and has several protrusions 2 on its side, which can increase the friction between the nasal cavity tissue and the main body 1, thereby ensuring the fixation effect of the upper end of the main body 1 in the nasal cavity.

[0024] In this embodiment, each of the protrusions 2 is arranged in a dot matrix on the side of the main body 1, so that the protrusions 2 on the side of the main body 1 are staggered in the vertical direction, thereby ensuring the fixation of the upper end of the main body 1 in the nasal cavity and also playing a certain role in preventing blood from flowing out of the nasal cavity.

[0025] See Figure 1 The connection 3 between the upper and lower ends of the main body 1 is provided with a circular flow-limiting strip 4, which not only fixes the main body 1 in the nasal cavity, but also limits the flow of blood out of the nasal cavity, thereby ensuring the degree of absorption of blood in the nasal cavity by the upper end of the main body 1.

[0026] See Figure 1 The upper edges of the main body 1 and the vent 11 are provided with chamfered structures 5, which improves the comfort of inserting the upper end of the main body 1 into the nasal cavity while reducing the risk of puncturing the nasal tissues.

[0027] To improve the visual appeal of the hemostatic sponge and thus reduce the aversion to its use, the lower edges of the main body 1 and the vent 11 may also be provided with a chamfered structure 5.

[0028] See Figure 1 , Figure 2 The lower side of the main body 1 has two opposite cut structures 6, which makes it easy to pinch the main body 1 for use and ensures control over the movement of the hemostatic sponge.

[0029] See Figure 2 The ventilation hole 11 is provided with several protrusions 7. The protrusions 7 are circular and each protrusion 7 is arranged at equal intervals along the axial direction of the main body 1, which increases the difficulty for blood in the nasal cavity to flow out through the ventilation hole 11 and ensures the absorption effect of the hemostatic sponge on the blood in the nasal cavity.

[0030] Example 2.

[0031] See Figure 3The structure of this embodiment is basically the same as that of embodiment one. The difference is that the ventilation hole 11 is provided with a number of grooves 8. The grooves 8 are circular and each groove 8 is arranged at equal intervals along the axial direction of the main body 1. While preventing blood in the nasal cavity from flowing out through the ventilation hole 11, it also reduces the processing and manufacturing difficulty of the main body 1 to a certain extent.

[0032] Example 3.

[0033] See Figure 4 The structure of this embodiment is basically the same as that of Embodiment 1 and Embodiment 2. The difference is that a pull-wire groove 9 is provided on the lower end of the main body 1 along the circumference of the main body 1, and a pull-wire 91 is wound in the pull-wire groove 9. This makes it convenient for the user to pull the main body 1 out of the nasal cavity by pulling the pull-wire 91. This reduces the risk of the hands getting blood absorbed by the hemostatic sponge, while also ensuring the storage of the pull-wire 91 and reducing the impact of the pull-wire 91 hanging down during the use of the hemostatic sponge on the user experience.

[0034] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
