[0034] In order to enable those skilled in the technical field to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0035] The embodiment of this application provides a nasal cavity hemostasis device.

[0036] Embodiment 1 is as Figure 1 shown.

[0037] A nasal cavity hemostasis device includes a telescopic component 1 with a ventilation channel in the middle, which does not affect the normal breathing of the patient while hemostasis.

[0038] The telescopic component 1 includes an outer tube 11, an inner tube 12, a base 13, and a handle 14. The inner tube 12 is rotatably connected to the inside of the outer tube 11. The inner tube 12 is provided with a ventilation channel in the middle. The bottom end of the inner tube 12 is provided with a handle 14. The bottom end of the outer tube 11 is provided with a base 13. Rotate the handle 14 to move the inner tube 12 up and down along the outer tube 11, so as to adjust the position of the top end of the inner tube 12 and better align with the nasal cavity bleeding site.

[0039] A nasal cavity hemostasis device includes a hemostasis component 2 installed on the top of the telescopic component 1 to stop bleeding in the nasal cavity bleeding area;

[0040] The hemostatic component 2 includes an expandable rubber plug 21. A number of expandable rubber plugs 21 are arranged at the top of the movable end of the telescopic component 1. The expandable rubber plugs 21 are arranged adjacent to each other at equal intervals. The expandable rubber plugs 21 expand when encountering blood. The expandable rubber plug 21 is made of hydrophilic modified silica gel and its volume expands rapidly when encountering blood.

[0041] A blood collection groove 22 is formed in the middle of a number of the expandable rubber plugs 21. A collection tube 23 is installed inside the blood collection groove 22. The inner cavity of the collection tube 23 is communicated with the expandable rubber plug 21. Collection holes 24 corresponding to the position of the expandable rubber plug 21 are formed on the surface of the collection tube 23. The collection tube 23 is made of a flexible material and has a certain ductility to prevent the expandable rubber plug 21 from expanding and breaking the collection tube 23. A micro air pump 25 is installed at the bottom of the telescopic component 1. An output end of the micro air pump 25 is installed with a connecting pipe 26. The connecting pipe 26 extends to the upper end of the inner tube 12 through the ventilation channel. The top of the connecting pipe 26 is connected with a negative pressure tube 27. Negative pressure holes adapted to the negative pressure tube 27 are formed on the side wall of the inner tube 12 and the side wall of the expandable rubber plug 21. The negative pressure tube 27 passes through the negative pressure hole and is communicated with the collection tube 23. A first electromagnetic valve 28 is installed inside the negative pressure tube 27. When locking the nasal bleeding area, the micro air pump 25 is started and the first electromagnetic valve 28 is opened. At this time, the inside of the collection tube 23 is in a negative pressure state. Then the handle 14 is rotated to drive the expandable rubber plug 21 etc. to move upward through the inner tube 12 until the blood at the bleeding point is sucked into the collection tube 23. The blood flows into the collection tube 23 along the collection holes 24. The blood triggers the corresponding expandable rubber plug 21 at this place, mechanically locking the bleeding point. The expandable rubber plug 21 expands to compress and stop bleeding at the bleeding point. The collection holes 24 are directly opposite to the expandable rubber plug 21 to achieve a zero-delay response of "expanding when sucking blood".

[0042] A gel bag 29 is pasted on the surface of the expandable rubber plug 21. The gel bag 29 is filled with a coagulation gel. Two gel bags 29 cover the surface of each expandable rubber plug 21, respectively located on the upper and lower sides of the expandable rubber plug 21 to wrap the expandable rubber plug 21 therein. That is, they are respectively located on both sides of the collection tube 23 of the expandable rubber plug 21. When the expandable rubber plug 21 expands, due to the volume expansion, the adhesion between the gel bag 29 and the expandable rubber plug 21 will be torn, so that the coagulation gel in the gel bag 29 flows out to the surface of the expandable rubber plug 21 and then is driven by the expandable rubber plug 21 to press on the nasal bleeding area. The physical blockage of the expandable rubber plug 21 + the coagulation promotion of the coagulation gel make the hemostatic effect better and the recurrence rate lower.

[0043] A barrier ring 3 is arranged at the top of the movable end of the telescopic component 1. To prevent the inner end tip from touching the nasal cavity side wall and damaging the nasal mucosa.

[0044] A nasal hemostasis device, including a plugging component 4, is installed on the upper part of the telescopic component 1 to plug the lower end of the nasal cavity and prevent blood from dripping out.

The inflatable airbag 41 is arranged on the outer side of the upper part of the outer tube 11, and the plugging ring 42 is arranged in the middle of the outer side of the inflatable airbag 41. The inflatable airbag 41 is communicated with the connecting pipe 26 through an air supply pipe, and a second electromagnetic valve is arranged inside the air supply pipe. When nasal bleeding occurs, first insert the inflatable airbag 41 into the edge of the bottom of the nasal cavity, then start the micro air pump 25, open the second electromagnetic valve, and inflate the inflatable airbag 41 through the micro air pump 25 to plug the bottom of the nasal cavity. After plugging, the hemostasis component 2 is used to stop the bleeding at the bleeding site.

[0046] It also includes a fixing component 5, which is installed on the lower part of the telescopic component 1 to fix the overall position of the device. This can prevent the hemostasis component 2 from shifting during hemostasis, damaging the nasal mucosa, or even causing secondary nasal bleeding.

[0047] The fixing component 5 includes a clamping fixing part 51 and an inflatable fixing part 52. Both the clamping fixing component 5 and the inflatable fixing component 5 are installed on the lower part of the telescopic component 1.

Two clamping arms 517 are rotatably connected to the limiting column 516. The two clamping arms 517 are in an X shape, that is, the connection part of the two clamping arms 517 is rotatably connected to the limiting column 516. An electric push rod 518 is installed on the front side surface of the rotating plate 514. The output end of the electric push rod 518 is rotatably connected to two swing rods 519. The swing rods 519 are arranged one on the left and one on the right, and are respectively rotatably connected to the rear parts of the two clamping arms 517. When fixing, only need to adjust the swing arm 513 through the rotating slide rail 511 and the rotating ring 512, and then rotate through the rotating plate 514 to align the two clamping arms 517 with the other non-bleeding nasal cavity side wall or the nasal septum, select to clamp the nasal cavity side wall or the nasal septum, and then the electric push rod 518 retracts, driving the two clamping arms 517 to clamp inward, and finally clamping on the surface of the nasal cavity side wall or the nasal septum. A clamping ball column is provided at the front end of the clamping arm 517, which increases the clamping friction force and at the same time reduces the pain suffered by the patient during clamping.

[0049] A first fixed magnet 53 is installed on one side of the base 13. The first fixed magnet 53 is in contact with the surface of the rotating ring 512. After the clamping is completed, the first fixed magnet 53 is energized to adsorb and fix the rotating ring 512, thereby preventing the clamping arm 517 from shaking and affecting the clamping effect.

A fixing ring 526 is arranged on the outer side of the fixing airbag 525. When fixing, pull the moving ring 522 to adjust the ventilation pipe 524 and the fixing airbag 525 to align with the other non-bleeding nasal cavity of the patient, and then move it so that the fixing airbag 525 is located inside the nasal cavity. Then the micro air pump 25 is started to inflate the fixing airbag 525 to make it expand and fix it inside the nasal cavity. Second fixing magnets 54 are installed on both sides of the moving ring 522, and the inner sides of the second fixing magnets 54 are in contact with the surface of the outer tube 11. After the inflatable fixing is completed, the second fixing magnets 54 are electrified and adsorbed on the surface of the outer tube 11 to limit the moving ring 522 and prevent the inflatable fixing member 52 from shifting after being fixed.

[0051] When the present invention is in use:

[0052] First, the plugging assembly is inserted into the lower part of the bleeding nasal cavity, and then the micro air pump is started and the second solenoid valve is opened. The expansion airbag is inflated through the micro air pump to block the bottom of the nasal cavity.

Then turn the handle to drive the expansion rubber plug and the like to move upward through the inner tube until the blood at the bleeding point is sucked into the collection tube. The blood flows into the collection tube along the collection holes, and the blood triggers the corresponding expansion rubber plug at that place, mechanically locking the bleeding point. The expansion rubber plug expands to compress and stop the bleeding at the bleeding point. The collection holes are directly opposite to the expansion rubber plug to achieve a zero-delay response of "sucking blood and expanding immediately". When the expansion rubber plug expands, due to the volume expansion, the adhesion between the gel bag and the expansion rubber plug will be torn, so that the coagulation gel in the gel bag flows out to the surface of the expansion rubber plug and is then driven by the expansion rubber plug to press on the nasal bleeding area.
