Description

Nasal cavity tampon

Technical Field

The utility model relates to a nasal cavity tampon.

Background

Nasal bleeding is a condition encountered by most people, and occurs at ordinary times or after operations on chronic sinusitis and nasal polyps. At present, the nasal cavity is stuffed by hemostatic materials such as hemostatic sponge and the like, and the purpose of hemostasis is achieved through physical compression. The hemostatic sponge can expand after blood suction when in use, thereby realizing physical compression. When the hemostatic sponge needs to be taken out after hemostasis, because the hemostatic sponge is expanded and the blood coagulated on the surface can lead part of the hemostatic sponge to be bonded with the inner surface of the nasal cavity, secondary trauma can be caused if the hemostatic sponge is pulled out forcibly.

In order to solve the problems, part of the nasal cavity tampons adopt inflatable air bags to realize physical compression, and can be conveniently taken out after being deflated when needing to be taken out, but the nasal cavity tampons are necessary to be provided with inflation and deflation structures such as inflation tubes and inflation valves, so that the structure becomes complicated, the number of parts is increased, the size is increased, the nasal cavity tampon is inconvenient to carry and use, and the cost is high. And the components of the nasal cavity tampon must be sealed to avoid air leakage, and the process cost is high.

Detailed Description

The present invention will be further described with reference to the following examples.

The first embodiment is as follows:

as shown in fig. 1 and fig. 2, a nasal tampon according to a first embodiment includes a base 1, a central pillar 2, a hemostatic sponge pillar 3, and a soft and elastic outer mesh 4, wherein the outer mesh 4 is made of medical rubber.

A through hole 1.2 is arranged in the middle of the seat body 1, the central column 2 is cylindrical, the central column 2 movably penetrates through the through hole 1.2, the diameter of the through hole 1.2 is larger than that of the central column 2, a column cap 2.1 which is convenient for a user to grasp and pull out the central column is arranged at the outer end (the end which is positioned outside the nasal cavity when in use is the outer end, and the lower end shown in figure 2 is the outer end) of the central column 2, the column cap 2.1 is larger than the through hole, the column cap 2.1 is abutted against the outer surface of the seat body 1 (the surface which is positioned facing the nasal cavity when in use is the outer surface, and the lower surface shown in figure 2 is the outer surface), the hemostatic sponge column 3 is made of hemostatic sponge, the hemostatic sponge column 3 is wrapped on the part of the central column 2 which penetrates out from the inner surface of the seat body (the surface which is positioned facing the nasal cavity when in use is the inner surface, and the upper surface, the length of the part of the center pillar 2, which penetrates out of the inner surface of the seat body 1, is equal to or greater than the length of the hemostatic sponge column 3, the outer net cover 4 covers the outer surface of the hemostatic sponge column 3, the edge of the opposite seat body 1 of the outer net cover 4 is fixedly connected with the inner surface of the seat body 1, the fixed connection mode can be adhesion, the outer net cover 4 and the seat body 1 can also be made into a whole, a plurality of meshes 4.1 are arranged on the outer net cover 4, and the sponge at the position, corresponding to the meshes 4.1, of the hemostatic sponge column 3 is exposed out of the meshes 4.1.

When in actual use, can design several kinds of different size and dimension's nasal cavity tampons according to the size of nasal cavity, when needs stanch the nasal cavity, select the suitable nasal cavity tampon, during the tip that will be provided with hemostasis sponge post 3 and outer net cover 4 fills in the nasal cavity, hemostasis sponge post 3 absorbs the blood inflation through mesh 4.1, outer net cover 4 is stretched to the realization realizes the hemostasis by compression to the physics oppression of nasal cavity. When the hemostasis completion needs take out, grab tight column cap 2.1, toward outer extraction center pillar 2, form a mesopore in the centre to relieve the physics oppression to the nasal cavity, take out smoothly, and when hemostatic sponge post 3 because of absorbing the too hard of blood after-setting, the accessible is slightly pressed or is stretched into mesopore inside not hard up hemostatic sponge post 3 through instruments such as tweezers, also can stretch into the mesopore inside through the cylinder and instil into appropriate amount of liquid and make hemostatic sponge post 3 soft, thereby conveniently take out. The nasal cavity hemostatic plug is disposable.

In order to better grasp the column head 2.1 and more easily take out the center pillar 2, the two sides of the column head 2.1 are respectively provided with the sheet-shaped handles 2.2 extending outwards, the outer end parts of the sheet-shaped handles 2.2 are tilted, the outer edge edges of the sheet-shaped handles 2.2 are arc-shaped edges, when the center pillar 2 needs to be pulled out, the sheet-shaped handles 2.2 can be grasped by fingers, and therefore the center pillar 2 can be more easily taken out.

In order to be safer to use, the two side edges of the base body 1 are respectively provided with the limiting edges 1.1 which are used for abutting against the outer edge of the front end of the nostril in the embodiment, when the nasal cavity hemostatic plug is used, the limiting edges 1.1 abut against the outer edge of the front end of the nostril, the length of the nasal cavity hemostatic plug inserted into the nasal cavity can be limited through the limiting edges 1.1, and the nasal cavity hemostatic plug is prevented from being inserted too deeply.

The center pillar 2 of this embodiment also can adopt medical rubber to make for the whole of nasal cavity tampon has certain compliance, thereby adaptation nasal cavity that can be better. The seat body 1 can also be made of medical rubber and can also be made of medical plastic.
