Technical Field

[0001] The invention relates to the field of red blood streak removal equipment, and in particular to a red blood streak removal device. Background Art

[0002] Red blood streaks are mainly caused by the thinness of the facial stratum corneum, which makes it easier for the capillaries to contact and sense changes in the external environment, thus causing the capillaries to expand. Red blood streaks will form deposited spots, which are difficult to cure. Not only does it affect the beauty of the appearance, it will also cause psychological shadows and bring great inconvenience to normal life.

[0003] At present, the methods for removing red blood streaks are mainly divided into three types: living cell therapy, physical therapy, and chemotherapy. For physical therapy, specific wavelengths can be used to irradiate the skin, and the red blood streaks absorb the specific wavelengths, thereby achieving the removal effect, such as laser irradiation. However, the above removal methods have the following problems in actual application: First, laser irradiation is explosive, which causes great damage to the epidermis and subcutaneous tissue, and is easy to leave pigmentation; second, laser removal of red blood streaks is not accurate.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1-6As shown, a red blood streak removal device comprises a removal pen 1, wherein a needle 2 is provided at the bottom of the removal pen 1, and the needle 2 can quickly carbonize the red blood streak epidermal cells on the face after being heated; in this embodiment, the removal pen 1 is made of brass, and the needle 2 is made of tungsten, manganese and silver in a ratio of 1:8:15, wherein tungsten is also called titanium alloy, which can increase the hardness of the needle 2, improve wear resistance, toughness and heat resistance, manganese can improve the antioxidant property of the needle 2, and silver can make the needle 2 have anti-inflammatory and bactericidal effects, which can effectively improve the recovery speed and effect after the red blood streak treatment; specifically, the user heats the needle 2 to a certain temperature, and then contacts the needle tip of the needle 2 with the red blood streak position on the face. At this temperature, the epidermis of the red blood streak can be quickly carbonized. Since the needle tip of the needle 2 is thinner and the contact area is smaller, the lesion position can be carbonized more accurately, the contact with the normal skin tissue of the face is reduced, the treatment area is reduced to a large extent, and the skin damage is reduced. Since the carbonization area is small, the recovery speed is fast and the recovery effect is good.

[0028] When treating facial red blood streaks, the needle 2 may scald the patient or the operator due to negligence or misoperation of the user. In order to avoid the above situation and improve the safety factor of the removal pen 1, a protective jacket 3 is provided on the outside of the removal pen 1. The removal pen 1 is fixedly installed in the protective jacket 3 by a fixing component, and a length adjustment mechanism is provided on the protective jacket 3 for adjusting the length of the needle 2 extending out of the protective jacket 3.

[0029] Specifically, the length adjustment mechanism includes a mounting box 4 with an arched cross section arranged in the middle of the protective jacket 3, a section of arc-shaped strip holes 5 are arranged on the side wall of the mounting box 4, and a vertical first strip hole 6 is arranged on the wall surface of the protective jacket 3 located inside the mounting box 4;

[0030] A rotating shaft 7 is provided inside the installation box 4, a first connecting rod 8 is connected to one side of the middle of the rotating shaft 7, and one end of the first connecting rod 8 away from the rotating shaft 7 passes through the arc-shaped strip hole 5 and is connected to a paddle 9;

[0031] A second connecting rod 10 is connected to the other side of the middle of the rotating shaft 7, and the angle between the second connecting rod 10 and the first connecting rod 8 is an obtuse angle. The end of the second connecting rod 10 away from the rotating shaft 7 extends into the interior of the protective jacket 3 through the first hole 6, and a vertical third connecting rod 11 is hinged at its end. The bottom end of the third connecting rod 11 is connected with a needle tip protection sleeve 12 with an inverted trapezoidal cross section. A circle of first ridges 13 is provided on the top of the outer wall of the needle tip protection sleeve 12, and a circle of second ridges 14 is provided on the bottom of the inner wall of the protective jacket 3, and the first ridges 13 are against the upper surface of the second ridges 14;

[0032] The first torsion springs 15 are sleeved on the rotating shafts 7 on both sides of the first connecting rod 8. The needle tip protection cover 12 and the protective cover 3 are both made of heat-insulating materials to protect the heated needle 2.

[0033] Operating principle: Figure 6 As shown, the removal pen 1 is installed in the protective jacket 3. When the protective jacket 3 is held by the hand, the thumb of the operator is located near the paddle 9. The thumb is used to press the paddle 9 downward, that is, the paddle 9 causes the rotating shaft 7 to rotate counterclockwise, and at the same time drives the second connecting rod 10 to rotate counterclockwise. During the rotation of the second connecting rod 10, the third connecting rod 11 is lifted upward, that is, the needle tip protective sleeve 12 moves upward. Therefore, the needle tip 2 is exposed from the needle tip protective sleeve 12. After being exposed for a period of time, the lesion site can be treated. During the treatment process, the thumb needs to be pressed downward. The finger keeps pressing the paddle 9; when negligence or misoperation causes the entire device to fall off the operator's hand, at this time, under the action of the first torsion spring 15, the rotating shaft 7 is reset and rotated clockwise, that is, the needle tip protection sleeve 12 drops to the bottom position. At this time, the needle 2 is completely located in the needle tip protection sleeve 12, and the protective coat 3 and the needle tip protection sleeve 12 are both made of insulating material, which can prevent the heat on the needle 2 from being transferred to the protective coat 3 and the needle tip protection sleeve 12 to a certain extent, can effectively prevent burns, and improve the safety factor of the device during use.

[0034] Furthermore, when falling off, if the lower part of the removal pen 1 first contacts the patient or the operator, since the needle tip protection sleeve 12 is in a state where it can move freely up and down, that is, when an upward thrust is applied to the needle tip protection sleeve 12, the needle tip protection sleeve 12 will move upward, and at this time, a part of the needle 2 will be exposed outside the needle tip protection sleeve 12, so burns will also occur. In order to avoid the above situation, it is necessary to lock it after resetting. Then, a groove 16 is provided on the side of the paddle 9 close to the installation box 4, and the first connecting rod 8 is hinged in the groove 16 through a hinge shaft, and a second torsion spring 17 is provided on the hinge shaft. The outer walls of the installation box 4 on both sides of the arc-shaped strip hole 5 are provided with thorns 18 , and a pawl 19 corresponding to the thorn 18 is provided on the side wall of the paddle 9, and the pawl 19 is clamped in the thorn 18. After resetting, under the action of the second torsion spring 17, the pawl 19 will be clamped in the thorn 18, so that the length adjustment mechanism can be locked. At this time, when an upward thrust is applied to the needle tip protection sleeve 12, the needle tip protection sleeve 12 will not move upward, further improving the safety factor of the device; when the paddle 9 is pushed downward, due to the setting of the second torsion spring 17, a certain amplitude of relative rotation can be generated between the paddle 9 and the first connecting rod 8. At this time, the pawl 19 leaves the thorn 18, realizing unlocking, and completing the adjustment of the length of the needle 2 exposed outside the needle tip protection sleeve 12.

[0035] Furthermore, in order to facilitate the movement of the paddle 9 and avoid slipping, the upper surface of the paddle 9 is a downwardly concave arc surface, and a rubber sleeve can also be provided on the surface.

[0036] Furthermore, in order to prevent the needle tip protection sleeve 12 from tilting and getting stuck during the upward or downward movement, a vertical guide rod 20 is provided on the upper surface of the needle tip protection sleeve 12 and on the side opposite to the third connecting rod 11, and a guide block 21 is provided above the guide rod 20. The guide rod 20 is inserted into the guide block 21, and the guide block 21 is fixed on the inner wall of the protective sleeve 3.

[0037] In order to facilitate the removal pen 1 to be installed in the protective cover 3, as shown in FIG. Figure 4 As shown, the fixing assembly includes a limiting ring 22 fixedly arranged on the inner wall of the protective jacket 3 and located above the length adjustment mechanism, and a second hole 23 on the side wall of the protective jacket 3 above the limiting ring 22. A fixing sleeve 24 is provided inside the protective jacket 3 above the limiting ring 22. The fixing sleeve 24 is sleeved on the outer side of the removal pen 1 and forms a sliding fit with the removal pen 1.
