In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0027] EMBODIMENT

[0028] Refer to Figures 1-5For the first embodiment of the utility model, this embodiment provides a disposable medical nasal hair cleaner, can realize not need to wear forehead mirror, can drive blade 104 to rotate only by rotating knob 201 to correct direction, thereby effectively avoid blade 104 reverse and get stuck nasal hair, simultaneously still can replace spare protective cover 102 when protective cover 102 is blocked by intranasal mucosa, rapidly.

[0029] The trimming mechanism 100 includes a fixed sleeve 101, a protective cover 102 arranged outside the fixed sleeve 101, a rotating column 103 arranged inside the protective cover 102, a plurality of blades 104 fixedly connected to the outer surface of the rotating column 103 respectively, and a plurality of communication grooves 105 arranged outside the protective cover 102 and matched with the blades 104.

[0030] It should be noted that the protective cover 102 is used to protect the nasal cavity of medical staff, to avoid direct contact between the blade 104 and the nasal cavity, and the nasal hair can enter the protective cover 102 and contact the blade 104 through the communication groove 105. The rotating blade 104 can trim the nasal hair. The overall nasal hair cleaner is a medical consumable, which has low cost. In order to ensure surgical hygiene, it is discarded in a unified recycling area after one-time use, and is recycled and processed.

[0031] The driving mechanism 200 includes a knob 201 arranged outside the fixed sleeve 101, a driving column 202 fixedly connected to the outer surface of the knob 201, a transmission disc 203 fixedly arranged outside the outer surface of the driving column 202, and a limiting assembly 204 arranged outside the outer surface of the transmission disc 203 and matched with the rotating column 103.

[0032] It should be noted that through the limiting assembly 204, the blade 104 can be rotated only by rotating the knob 201 to the correct direction, so as to effectively avoid the situation that the nasal hair is stuck between the blade 104 and the protective cover 102.

[0033] The quick release mechanism 300 includes a first fixed block 301 fixedly connected to the outer surface of the fixed sleeve 101 on both sides respectively, a hinge block 302 hingedly connected to the outer surface of the first fixed block 301, a positioning strip 303 rotationally connected to the inner surface of the hinge block 302, a second fixed block 304 fixedly connected to the outer surface of the protective cover 102 on both sides and matched with the first fixed block 301, and a positioning block 305 fixedly connected to the outer surface of the second fixed block 304 and matched with the positioning strip 303.

[0034] And a disposable transparent storage box 400 matched with the fixed sleeve 101 and the protective cover 102.

[0035] More should be explained that the disposable transparent storage box 400 is provided with a plurality of standby protective covers 102, through the cooperation between the components in the quick release mechanism 300, the medical staff can quickly replace the standby protective cover 102 when encountering the protective cover 102 being blocked by the nasal mucosa, avoid long interruption, after replacing the protective cover 102, the medical staff can immediately continue to trim the nose hair, without waiting for cleaning or maintenance, so as to improve the trimming efficiency.

[0036] Specifically, the plurality of blades 104 are distributed in a circumferential array on the outer surface of the rotating column 103, and the plurality of communication grooves 105 all penetrate to the inner side of the protective cover 102.

[0037] Further, the limiting assembly 204 includes a mounting groove 204a opened on the outer surface of the transmission disc 203, a rotating column 204b fixedly installed on the inner wall of the mounting groove 204a, and a pawl 204c hingedly connected to the outer surface of the rotating column 204b.

[0038] Preferably, the limiting assembly 204 further includes a ratchet wheel 204d engaged with the outer surface of the pawl 204c, and a connecting column 204e fixedly connected to the outer end surface of the ratchet wheel 204d and cooperating with the rotating column 103.

[0039] It should be noted that the limiting assembly 204 further includes a spring 204f fixedly installed on the inner surface of the transmission disc 203, and a limiting groove 204g opened on the outer surface of the pawl 204c and cooperating with the spring 204f.

[0040] It should be explained that rotating the knob 201 can drive the transmission disc 203 to rotate synchronously, when rotating the knob 201 in the correct direction, the ratchet wheel 204d, the connecting column 204e, the rotating column 103 and the blade 104 can be driven to rotate synchronously through the cooperation of the transmission disc 203, the rotating column 204b and the pawl 204c, when rotating the knob 201 in the wrong direction, the ratchet wheel 204d will be pressed by the pawl 204c, and then reset through the reaction of the spring 204f.

[0041] Further, the outer surface of the ratchet wheel 204d is rotatably connected to the inner wall of the fixed sleeve 101, and the outer surface of the connecting column 204e is rotatably connected to the inner wall of the fixed sleeve 101.

[0042] Specifically, the outer end surface of the ratchet wheel 204d is fixedly connected to the outer end surface of the rotating column 103, and the other end of the spring 204f is fixedly connected to the inner wall of the limiting groove 204g.

[0043] In use, the handheld fixing sleeve 101 puts the protective cover 102 into the nasal cavity, and rotating the knob 201 drives the transmission disc 203 to rotate synchronously, when rotating the knob 201 in the correct direction, the ratchet wheel 204d, the connecting column 204e, the rotating column 103 and the blade 104 can be driven to rotate synchronously through the cooperation of the transmission disc 203, the rotating column 204b and the pawl 204c, when rotating the knob 201 in the wrong direction, the ratchet wheel 204d will be pressed by the pawl 204c, and then reset through the reaction of the elastic sheet 204f, so that the blade 104 cannot be rotated, so as to realize the effect that only rotating the knob 201 in the correct direction can drive the blade 104 to rotate.

[0044] When the protective cover 102 is blocked by the nasal mucosa, rotating the hinged block 302 drives the positioning strip 303 to move to a position away from the inner wall of the positioning block 305, thereby releasing the limiting of the protective cover 102, after replacing the new protective cover 102, moving the positioning strip 303 to the position in contact with the inner wall of the positioning block 305, and reversely rotating the hinged block 302, the hinged block 302 drives the positioning strip 303 to tightly fit with the inner wall of the positioning block 305, so as to realize the effect that when the protective cover 102 is blocked by the nasal mucosa, the standby protective cover 102 can be quickly replaced, avoiding long-term interruption of use.

[0045] In summary, through the limiting assembly 204, the effect that only rotating the knob 201 in the correct direction can drive the blade 104 to rotate can be realized, so as to effectively avoid the situation that the nasal hair is stuck between the blade 104 and the protective cover 102; through the cooperation between the components in the quick release mechanism 300, the medical staff can quickly replace the standby protective cover 102 when the protective cover 102 is blocked by the nasal mucosa, avoiding long-term interruption of use, after replacing the protective cover 102, the medical staff can immediately continue to trim the nasal hair, without waiting for cleaning or maintenance, so as to improve the trimming efficiency.
