Description

Technical Field

[0001] This invention belongs to the field of medical technology, specifically relating to containers for surgical instruments, and more particularly to a device for holding cosmetic needles and its method of use. Background Technology

[0002] The cosmetic needle is first placed in a protective sleeve, which is then covered with a cap to form a cosmetic needle assembly. The cosmetic needle assembly is then housed in a receiving device. However, in related technologies, the size of the receiving area used to house the receiving device is fixed, and the size of the receiving area is the same as that of the cosmetic needle assembly, making it difficult to place the cosmetic needle in the receiving device, or the size is larger than the cosmetic needle assembly, causing the cosmetic needle assembly to fall out and be damaged.

[0003] Therefore, to address the technical problem that the size of the receiving device is larger than that of the cosmetic needle component, making the cosmetic needle component easy to fall out and be damaged after placement, or that the size is the same as that of the cosmetic needle component, making it difficult to place the cosmetic needle component, a cosmetic needle receiving device and its usage method need to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0005] This disclosure provides at least one embodiment of a cosmetic needle receiving device and its method of use.

[0006] In a first aspect, embodiments of this disclosure provide a cosmetic needle receiving device, comprising:

[0007] A sleeve, wherein a plurality of receiving mechanisms are equidistantly arranged on one side along the length direction, and the receiving mechanisms are adapted to accommodate a cosmetic needle assembly;

[0008] The receiving mechanism includes: a flexible strip;

[0009] The flexible strip is connected to the sleeve, and the length direction of the flexible strip is parallel to the width direction of the sleeve;

[0010] Both sides of the flexible strip are connected to rigid strips, and the length direction of the rigid strips is parallel to the width direction of the sleeve.

[0011] The flexible strip and the rigid strip are both arc-shaped on the side away from the sleeve to form a receiving area for accommodating the cosmetic needle assembly;

[0012] When the sleeve is unrolled, the receiving area is elliptical. When the sleeve is rolled into a tube, the receiving area is approximately circular. The receiving area gradually shrinks from an elliptical shape to a circular shape, and the arc length of the circular arc is greater than the arc length of the semicircle, so as to clamp the beauty needle assembly.

[0013] In one alternative implementation, the rigid strips of two adjacent receiving mechanisms are in contact;

[0014] The areas on the sleeve corresponding to the flexible and rigid strips are made of rigid material, while the areas between the rigid material areas corresponding to two adjacent receiving mechanisms on the sleeve are made of flexible material.

[0015] In one optional embodiment, a supporting mechanism is provided at one end of the receiving mechanism;

[0016] The supporting mechanism includes: a supporting block;

[0017] When the sleeve is wound into a cylindrical shape, one end of the receiving area is tapered, and the diameter is longer closer to the end of the receiving area;

[0018] The top surface of the support block has a recess to accommodate the end of the beauty needle assembly;

[0019] When the sleeve is wound into a cylindrical shape, the conical portion of the receiving area contacts and pushes the support block outward.

[0020] In one alternative embodiment, the inner wall of the recess is provided with a spiral groove;

[0021] An arc-shaped strip is provided within the receiving area, and the arc-shaped strip is connected to the connecting rod;

[0022] The connecting rod is provided with a protrusion, which is located inside the spiral groove;

[0023] When the support block moves outward, the protrusion engages with the spiral groove to cause the arc strip to rotate.

[0024] In one optional embodiment, a sponge layer is provided on the arc-shaped strip, and the sponge layer passes through the arc-shaped strip and contacts the inner wall of the receiving area;

[0025] The sponge layer absorbs iodine tincture;

[0026] When the sleeve is rolled into a cylindrical shape, the inner wall of the receiving area is squeezed to apply iodine solution to the gaps of the cosmetic needle components.

[0027] In one alternative embodiment, the sleeve is provided with a spring plunger corresponding to the support block;

[0028] The spring plunger is connected to the bottom surface of the support block via a connecting strip.

[0029] In one optional embodiment, the sleeve is provided with a hook and loop fastener on the side without the receiving mechanism, and the hook and loop fastener fastener is located near one end face of the sleeve in the length direction.

[0030] The other end face of the sleeve along its length is provided with a hook and loop fastener, which extends out of the sleeve.

[0031] When the sleeve is rolled into a tube, the hook and loop sides of the hook and loop fasteners adhere to each other to keep the sleeve in a tube shape.

[0032] Secondly, this disclosure also provides a method of using the above-described cosmetic needle receiving device, comprising:

[0033] When the sleeve is unrolled, the receiving area is elliptical. The beauty needle component is placed into the receiving area, and then the sleeve is rolled into a tube, and the receiving area is approximately circular. The receiving area gradually shrinks from an elliptical shape to a circular shape, and the arc length of the circular arc is greater than the semicircular arc length, so as to clamp the beauty needle component.

[0034] In one alternative implementation, when the sleeve is rolled into a cylindrical shape, the inner wall of the receiving area is squeezed to apply iodine solution inside the sponge to the gaps of the cosmetic needle assembly.

[0035] In one alternative implementation, as the sheath unfolds from the tube, the spring plunger resets, causing the support block to move inward, so that the end of the cosmetic needle assembly protrudes from the sheath.

[0036] The beneficial effects of this invention are as follows: This cosmetic needle receiving device includes: a sheath, on one side of which are equidistantly arranged a plurality of receiving mechanisms, the receiving mechanisms being adapted to receive cosmetic needle components; the receiving mechanism includes: a flexible strip; the flexible strip is connected to the sheath, the length direction of the flexible strip being parallel to the width direction of the sheath; both sides of the flexible strip are connected to rigid strips, the length direction of the rigid strips being parallel to the width direction of the sheath; the sides of the flexible strip and the rigid strip away from the sheath are both arc-shaped to form a receiving area for receiving cosmetic needle components; when the sheath is unfolded, the receiving area is elliptical, and when the sheath is rolled into a cylinder, the receiving area is approximately circular, the receiving area gradually shrinks from an elliptical arc to a circular arc, and the arc length of the circular arc is greater than the semicircular arc length, so as to clamp the cosmetic needle components, thereby realizing that when the sheath is unfolded, it is convenient to place the cosmetic needle components in the receiving area, and when the sheath is rolled into a cylinder, it can clamp the cosmetic needle components to prevent them from falling out.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0054] The cosmetic needle is first placed in a protective sleeve, which is then covered with a cap to form a cosmetic needle assembly. The cosmetic needle assembly is then housed in a receiving device. However, in related technologies, the size of the receiving area used to house the receiving device is fixed, and the size of the receiving area is the same as that of the cosmetic needle assembly. This makes it difficult to place the cosmetic needle in the receiving device, or the size is too large for the cosmetic needle assembly, causing the cosmetic needle assembly to fall out and be damaged.

[0055] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0056] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0057] like Figure 1 and Figure 2As shown, at least one disclosed embodiment provides a cosmetic needle receiving device, including: a sheath 1, on one side of which a plurality of receiving mechanisms 2 are equidistantly arranged along the length direction, the receiving mechanisms 2 being adapted to receive cosmetic needle components; the receiving mechanism 2 includes: a flexible strip 21; the flexible strip 21 is connected to the sheath 1, the length direction of the flexible strip 21 being parallel to the width direction of the sheath 1; both side walls of the flexible strip 21 are connected to rigid strips 22, the length direction of the rigid strips 22 being parallel to the width direction of the sheath 1; the flexible strip 21 and the rigid strips 22 are connected to rigid strips 22; the flexible strip 21 and the rigid strips 22 are connected to rigid strips 22. The side of strip 22 away from the sleeve 1 is all arc-shaped to form a receiving area 23 for accommodating the beauty needle assembly. When the sleeve 1 is unfolded, the receiving area 23 is elliptical arc-shaped. When the sleeve 1 is rolled into a cylindrical shape, the receiving area 23 is approximately circular arc-shaped. The receiving area 23 gradually shrinks from an elliptical arc shape to a circular arc shape, and the arc length of the circular arc is greater than the arc length of the semicircle, so as to clamp the beauty needle assembly. This makes it easy to place the beauty needle assembly in the receiving area 23 when the sleeve 1 is unfolded, and can clamp the beauty needle assembly to prevent the beauty needle assembly from falling out when the sleeve 1 is rolled into a cylindrical shape.

[0058] like Figure 1 and Figure 2 As shown, in one optional embodiment, the rigid strips 22 of two adjacent receiving mechanisms 2 are in contact; the area on the sleeve 1 corresponding to the flexible strip 21 and the rigid strip 22 is made of rigid material, and the area between the rigid material areas of two adjacent receiving mechanisms 2 on the sleeve 1 is made of flexible material.

[0059] In this embodiment, the area on the sleeve 1 corresponding to the flexible strip 21 and the rigid strip 22 can be a rigid area 12, and the area between adjacent rigid areas 12 is a flexible area 13.

[0060] In this embodiment, as the unfolded sleeve 1 is rolled into a cylindrical shape, the adjacent rigid strips 22 come into contact and squeeze each other, causing the originally elliptical receiving area 23 to gradually shrink into an approximately circular arc shape, thus holding the beauty needle assembly placed in the receiving area 23 tightly.

[0061] like Figure 7 As shown, in this embodiment, when the receiving area 23 is elliptical, the beauty needle assembly can be easily placed into the receiving area 23. That is, at this time, the width of the opening on the side wall of the receiving area 23 is greater than the diameter of the beauty needle assembly, which facilitates the placement of the beauty needle assembly into the receiving area 23. When the receiving area 23 is circular, it can ensure the clamping of the beauty needle assembly and prevent the beauty needle assembly from falling out.

[0062] In this embodiment, the arc length of the perfect circle is greater than the arc length of the semicircle, which can better clamp the beauty needle assembly. That is, when the sleeve 1 is rolled into a cylindrical shape, the arc length of the semicircle corresponding to the complete circle of the receiving area 23 is less than the arc length of the perfect circle at this time.

[0063] like Figure 3 and Figure 5 As shown, in one optional embodiment, a supporting mechanism 3 is provided at one end of the receiving mechanism 2; the supporting mechanism 3 includes: a supporting block 31: when the sleeve 1 is rolled into a cylindrical shape, one end of the receiving area 23 is tapered, and the diameter is longer closer to the end of the receiving area 23; a recess 32 is provided on the top surface of the supporting block 31 to receive the end of the beauty needle assembly; when the sleeve 1 is rolled into a cylindrical shape, the tapered part of the receiving area 23 contacts and pushes the supporting block 31 outward.

[0064] In this embodiment, when the sleeve 1 is unfolded, the support block 31 is in the initial position and is located in the conical part of the receiving area 23. At this time, the beauty needle assembly can be placed in the receiving area 23. One end of the beauty needle assembly is located in the recess 32, and the other end protrudes from the sleeve 1. The gap of the beauty needle assembly is already at the sponge layer 37.

[0065] like Figure 8 As shown, in this embodiment, after the beauty needle assembly is placed, the sleeve 1 can be rolled up into a cylindrical shape. At this time, the conical part of the receiving area 23 will push the support block 31 outward, that is, the length of the support block 31 extending out of the sleeve 1 increases. When the support block 31 moves outward, the arc strip 34 rotates, so that the iodine on the sponge layer 37 can be completely applied to the gaps of the beauty needle assembly for disinfection. After the sleeve 1 is rolled up, the part of the beauty needle assembly protruding from the sleeve 1 can be manually pressed into the sleeve 1 to avoid damage to the protruding part of the beauty needle assembly. Since the support block 31 extends outward from the sleeve 1, the originally protruding end of the beauty needle can be pressed completely into the sleeve 1 by manual or other means.

[0066] like Figure 3 and Figure 4 As shown, in one optional embodiment, the inner wall of the recess 32 is provided with a spiral groove 33; an arc-shaped strip 34 is provided in the receiving area 23, and the arc-shaped strip 34 is connected to the connecting rod 35; a protrusion 36 is provided on the connecting rod 35, and the protrusion 36 is located in the spiral groove 33; when the supporting block 31 moves outward, the protrusion 36 cooperates with the spiral groove 33 to make the arc-shaped strip 34 rotate.

[0067] In this embodiment, when the support block 31 finishes moving outward, the arc strip 34 rotates through the entire gap.

[0068] In this embodiment, the arc-shaped strip 34 is flexible.

[0069] like Figure 3 and Figure 4As shown, in one optional embodiment, a sponge layer 37 is provided on the arc-shaped strip 34, and the sponge layer 37 passes through the arc-shaped strip 34 and contacts the inner wall of the receiving area 23; the sponge layer 37 absorbs iodine; when the sleeve 1 is rolled into a cylindrical shape, the inner wall of the receiving area 23 squeezes the sponge so that the iodine in the sponge is applied to the gaps of the beauty needle assembly.

[0070] like Figure 6 As shown, in one optional embodiment, the sleeve 1 is provided with a spring plunger 38 corresponding to the support block 31; the spring plunger 38 is connected to the bottom surface of the support block 31 through a connecting strip 39.

[0071] In this embodiment, when the support block 31 is pushed outward, the spring plunger 38 is stretched accordingly to drive the support block 31 to reset when the sleeve 1 is unfolded.

[0072] In this embodiment, when the sleeve 1 is rolled into a cylindrical shape, the receiving area 23 clamps the beauty needle assembly. At this time, the beauty needle assembly can be manually pressed to retract into the sleeve 1, and the force provided by the spring plunger 38 cannot drive the support block 31 to reset.

[0073] In this embodiment, when the sleeve 1 unfolds from the cylindrical shape, the receiving area 23 unfolds from the circular arc shape back to the elliptical arc shape. At this time, the spring plunger 38 can reset and drive the support block 31 to reset, so that one end of the beauty needle assembly protrudes from the sleeve 1, making it easier to take out the beauty needle assembly from the receiving area 23.

[0074] like Figure 1 As shown, in one optional embodiment, the sleeve 1 is provided with a hook and loop fastener on the side without the receiving mechanism 2, and the hook and loop fastener is located near one end face of the sleeve 1 in the length direction; the other end face of the sleeve 1 in the length direction is provided with a hook and loop fastener hook face 11, and the hook and loop fastener hook face 11 extends out of the sleeve 1; when the sleeve 1 is rolled up into a cylindrical shape, the hook and loop fastener fastener and the hook and loop fastener hook face 11 are attached to each other so that the sleeve 1 maintains a cylindrical shape.

[0075] At least one other disclosed embodiment also provides a method of using the above-described beauty needle receiving device, comprising: when the sleeve 1 is unfolded, the receiving area 23 is in the shape of an elliptical arc; placing the beauty needle assembly into the receiving area 23; then rolling the sleeve 1 into a cylindrical shape, the receiving area 23 is in the shape of a circular arc; the receiving area 23 gradually shrinks from the elliptical arc shape to a perfect circular arc shape, and the arc length of the perfect circular arc is greater than the arc length of the semicircle, so as to clamp the beauty needle assembly.

[0076] In one alternative embodiment, when the sleeve 1 is rolled into a cylindrical shape, the inner wall of the receiving area 23 is squeezed to apply iodine solution inside the sponge to the gaps of the cosmetic needle assembly.

[0077] In one alternative embodiment, when the sheath 1 unfolds from the cylindrical shape, the spring plunger 38 resets, causing the support block 31 to move inward, so that the end of the cosmetic needle assembly protrudes from the sheath 1.

[0078] In summary, this cosmetic needle receiving device includes: a sheath 1, on one side of which a plurality of receiving mechanisms 2 are equidistantly arranged along the length direction, the receiving mechanisms 2 being adapted to receive cosmetic needle components; each receiving mechanism 2 includes: a flexible strip 21; the flexible strip 21 is connected to the sheath 1, and the length direction of the flexible strip 21 is parallel to the width direction of the sheath 1; both side walls of the flexible strip 21 are connected to rigid strips 22, the length direction of the rigid strips 22 being parallel to the width direction of the sheath 1; the flexible strip 21 and the rigid strips 22 are separated by... One side of the sleeve 1 is curved to form a receiving area 23 for accommodating the beauty needle assembly. When the sleeve 1 is unfolded, the receiving area 23 is elliptical. When the sleeve 1 is rolled into a cylinder, the receiving area 23 is approximately circular. The receiving area 23 gradually shrinks from an elliptical shape to a circular shape, and the arc length of the circular arc is greater than the arc length of the semicircle, so as to clamp the beauty needle assembly. This makes it easy to place the beauty needle assembly in the receiving area 23 when the sleeve 1 is unfolded, and can clamp the beauty needle assembly to prevent it from falling out when the sleeve 1 is rolled into a cylinder.
