Abstract
Description
Technical Field
[0001] The utility model relates to a hemostatic device, in particular to a nasal hemostatic device. Background Art
[0002] Nosebleed is one of the common clinical symptoms, and one or more bleeding points can often be seen at the front of the nasal cavity. At the same time, within a period of time after the nosebleed stops, the broken ends of blood vessels can also be seen on the surface of the nasal mucosa, showing as localized protrusions. Currently, nasal packing and electrocoagulation are mostly used in clinical work. The nasal packing method is to fill the nasal cavity with vaseline gauze, which causes great pain to the patient. And the broken ends of blood vessels left after the gauze is removed also have a high risk of rebleeding. The electrocoagulation method is to use an electrocoagulation pen to cauterize the blood vessels to stop bleeding, which requires certain surgical preparations and instrument support. Some clinical doctors often fail to stop bleeding in time because they cannot quickly obtain instrument support. Utility Model Content

[0021] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0022] See attached Figure 1 , Figure 1 The schematic diagram of the structure of a nasal hemostasis device is shown in FIG. The nasal hemostasis device includes: a pipe 10 and a push rod 20. The pipe 10 includes a first end and a second end. The first end is provided with a plug 11, and a cotton ball 12 wraps the first end and the plug 11; the second end is provided with a buckle cover 13; a sliding piston 14 is provided in the pipe 10, and a silver nitrate solution 15 is filled between the sliding piston 14 and the plug 11. The push rod 20 includes a rod 21 and a pressing portion 22 connected to one end of the rod 21. The other end of the rod 21 can be inserted into the pipe 10 from the second end to push against the sliding piston 14, so that the plug 11 is separated from the first end and the silver nitrate solution 15 enters the cotton ball 12.
[0023] Specifically, the pipe 10 and the push rod 20 can be made of plastic material. The silver nitrate solution 15 uses a 50% silver nitrate solution to better achieve nasal hemostasis. It should be noted that the concentration of the silver nitrate solution 15 can also be other concentrations, and its concentration is not limited. In order to store the silver nitrate solution 15 away from light, the pipe 10 is brown as a whole. The length of the pipe 10 is 5 cm to 13 cm, for example, 12 cm. The diameter of the pipe 10 is 0.3 cm to 0.5 cm.
[0024] Optionally, an inner groove 16 is provided on one side of the sliding piston 14 near the second end, and an outer protrusion 23 is provided at the end of the rod portion 21, and the outer protrusion 23 can be matched and snapped into or screwed into the inner groove 16, so as to facilitate pushing the sliding piston 14 through the push rod 20. Preferably, the outer protrusion 23 has an external thread, and the inner groove 16 has a matching external thread.
[0025] The first end of the pipe 10 extends inward to form an opening, and the plug 11 blocks the opening. That is, the opening is smaller than the diameter of the pipe 10. Thus, on the one hand, the plug 11 does not need to be designed to be too large and is easier to push open. On the other hand, when in use, the smaller opening makes it easier to control the amount of silver nitrate solution 15 entering the absorbent cotton ball 12. The plug 11 and the sliding piston 14 are both made of rubber.
[0026] The buckle cover 13 is designed to prevent the silver nitrate solution 15 in the tube 10 from leaking during carrying or transportation.
[0027] Usage: After observing and finding the broken end of the blood vessel, remove the buckle cover 13 of the pipe fitting 10, gently screw the outer protrusion 23 of the push rod 20 into the sliding piston 14 in the pipe fitting 10, ensure that the connection is in place, press the part 22, push the sliding piston 14 to slide, and the pressure of the silver nitrate solution 15 will push out the plug 11 at the first end, and the silver nitrate solution 15 will flow out and soak the absorbent cotton ball 12. The cotton head that has absorbed the solution will contact the bleeding point of the nasal cavity or around the broken end of the blood vessel until the mucosa turns white and there is no bleeding. The bleeding can be stopped by the effect of the silver nitrate solution 15. The amount of silver nitrate solution 15 can be controlled by the pressure during the process, which can be used for multiple cauterizations, and can also prevent excessive solution from burning normal mucosa.
[0028] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
