Problems solved by technology

However, the traditional extrusion method cannot squeeze from the surroundings of the acne to the middle at the same time. When squeezing from the left and right directions, part of the dirt is squeezed to the upper and lower positions, and when squeezing from the up and down directions, some of the dirt is squeezed to the left and right positions, resulting in There are dead angles in extrusion, the dirt is not discharged completely, and it is easy to leave marks on the skin surface

Embodiment 1

[0024] see Figure 1~3 , a semi-automatic acne needle, comprising a needle 1, a sleeve 2, a first piston 3, a shrinking mouth 4 and an elastic sleeve 5, the first piston 3 is arranged in the sleeve 2, and the lower end of the first piston 3 Connect the needle 1, the shrink mouth 4 includes several elastic support pieces 6 and elastic rings 7, the elastic support pieces 6 are evenly distributed on the lower end of the sleeve 2, and the elastic support pieces 6 are fixed on the elastic ring 7 at the lower end , the elastic ring 7 is connected to the casing 2 through the elastic sleeve 5, the elastic supporting sheet 6 is provided with a through hole 8, and the casing 2 is provided with a slide rail 9 and a slider 10, and the slider 10 slides along the slide rail 9, one end of the pull rope 11 is fixed on the slide block 10, and the other end is also fixed on the slide block 10 after passing around the through hole 8, and the pull rope 11 is fixed on the slide block 10 in the thr...

Embodiment 2

[0032] see Figure 4The difference between this embodiment and Embodiment 1 is that the elastic ring 7 includes a bellows 14 and an elastic ferrule 13, the bellows 14 are connected end to end to form a ring structure, and the bellows 14 is arranged on the elastic Inside the ferrule 13, the bellows 14 is connected to the syringe 16 through a pipe 15, and the space between the bellows 14 and the elastic collar 13 is filled with liquid. When there is a lot of liquid filled in the bellows 14, the length of the bellows 14 is elongated, and the end of the bellows 14 is connected, so that the diameter of the circle surrounded by the bellows 14 becomes larger. Similarly, when the liquid filled in the bellows 14 When it is smaller, the diameter of the circle formed by the bellows 14 becomes smaller. The bellows 14 is connected to the injection tube 16 through the pipeline 15, and the liquid is injected into the bellows 14 through the injection tube 16 to adjust the length of the bello...

Embodiment 3

[0034] see Figure 5 The difference between this embodiment and Embodiment 2 is that the lower end of the casing 2 is provided with a conical bucket 22, the upper end of the conical bucket 22 has a large opening, and the lower opening is small, and the upper opening of the conical bucket 22 is fixed. On the sleeve 2 , the opening at the lower end is aligned with the middle position of the elastic ring 7 . When the first piston 3 moves upward to generate negative pressure, the elastic sleeve 5 deforms inwardly, and the elastic sleeve 5 contacts the conical bucket 22 after deformation, and the conical mouth is used to support the elastic sleeve 5 to avoid excessive deformation of the elastic sleeve 5 The lower end of 2 is blocked.

[0035] Specifically, the syringe 16 includes a syringe 24 and a second piston 23, the second piston 23 slides in the syringe 24, the second piston 23 is provided with a piston rod 27, and the slider 10 It is connected with the piston rod 27 through...

Abstract

The invention discloses a semi-automatic acne needle, which comprises a needle, a sleeve, a first piston, a retracting mouth and an elastic sleeve, the first piston is arranged in the sleeve, and the lower end of the first piston is connected to the needle, so The shrink nozzle includes several elastic supporting pieces and elastic rings, the elastic supporting pieces are evenly distributed on the lower end of the sleeve, the elastic ring is fixed at the lower end of the elastic supporting piece, and the elastic ring is connected to the sleeve through the elastic sleeve tube, the elastic support piece is provided with a through hole, the sleeve is provided with a slide rail and a slider, the slider slides along the slide rail, one end of the pull rope is fixed on the slide block, and the other end goes around The through hole is also fixed on the slider, and the pulling rope is covered with a wire tube at the position from the through hole to the slide rail, and a spring is provided in the sleeve tube to push the first piston away from the contraction nozzle. . The present invention is to provide a semi-automatic acne needle, which can simultaneously squeeze acne from all sides, and the extrusion is clean and thorough, and scars are not easy to be left.

Description

technical field [0001] The invention relates to the technical field of acne needles, in particular to a semi-automatic acne needle. Background technique [0002] Acne is a chronic inflammatory skin disease of the pilosebaceous unit. It mainly occurs in adolescents and has a great psychological and social impact on adolescents, but it can often be relieved or cured naturally after puberty. The clinical manifestations are characterized by pleomorphic skin lesions such as acne, papules, pustules, and nodules that are prone to occur on the face. The acne needle has a needle, which is used to pierce the acne epidermis and squeeze out the dirt inside. However, the traditional extrusion method cannot squeeze from the surroundings of the acne to the middle at the same time. When squeezing from the left and right directions, part of the dirt is squeezed to the upper and lower positions, and when squeezing from the up and down directions, some of the dirt is squeezed to the left and ...
