Description

Technical Field

[0001] The utility model relates to the technical field of beauty needles, in particular to a beauty needle structure for preventing penetration. Background Art

[0002] To solve problems such as skin pigmentation, dullness, and relaxation, the beauty industry usually uses the method of injecting liquid medicine into the skin for repair. The traditional liquid medicine injection method is to first pierce the skin with an injection needle, and then inject the liquid medicine along the needle with a syringe. This method has at least the following problems.

[0003] Chinese Patent Publication No.: CN219700699U discloses a beauty needle head assembly, including a housing, a syringe barrel, a driving rod, a needle disc, and multiple steel needles evenly distributed at the bottom of the needle disc. By making the steel needles in a sheet shape, the thickness of the steel needles does not exceed 0.10 mm, and the width does not exceed 0.15 mm; a longitudinal liquid guide groove is provided on the inner wall of the syringe barrel, and a notch corresponding to the longitudinal liquid guide groove is provided on the outer wall of the needle disc. When the lower end surface of the housing is pressed tightly against the patient's skin, the liquid medicine in the liquid medicine cavity can flow out along the longitudinal liquid guide groove and the notch into the cavity formed by the inner wall of the housing and the patient's skin, forming a liquid medicine layer floating on the patient's skin. Then, by driving the syringe barrel to move up and down with the driving rod, the steel needles can penetrate through the liquid medicine layer and puncture holes can be made on the patient's skin, so that the liquid medicine in the liquid medicine layer can penetrate into the patient's skin along the puncture holes and be absorbed by it. Since it is passive drug delivery, it will not cause local swelling and has good safety. Moreover, the size of the steel needles is small, the trauma is small, and the pain is weak.

[0004] It can be seen that in the prior art, most of the liquid medicine is injected into patients through blunt needles and sharp needles. However, the existing sharp needles are provided with inclined surfaces for discharging liquid medicine. Therefore, when the sharp needles puncture, they are likely to enter the blood vessels, and then the liquid medicine enters the blood vessels, which has an impact on the patient's body. The tip of the blunt needle does not have a sharp edge, and its puncture process may not be as fast and direct as that of the sharp needle. Therefore, it may bring stronger pain to the patient. Secondly, when injecting liquid medicine into the patient, it is necessary to use the needle to puncture the container filled with liquid medicine. After multiple punctures, it is easy to affect the puncture effect of the needle. Content of the Utility Model

[0005] The purpose of the utility model is to provide a beauty needle structure for preventing penetration, which can avoid the situation that when a sharp needle punctures, it is easy to enter the blood vessels, and then the liquid medicine enters the blood vessels, which has an impact on the patient's body.

[0030] The following will elaborate on some embodiments of the present utility model with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0031] Please refer to Figures 1-8, an embodiment of the present utility model provides an anti-piercing beauty needle structure, which includes a first needle sleeve 2 sleeved on one end of a syringe 1. One end of the first needle sleeve 2 is provided with an inner needle head 8. One end of the inner needle head 8 is a solid conical structure. One end of the inner needle head 8 is a solid sharp needle. Symmetrical first side holes 9 are opened on the side of the inner needle head 8, that is, the head of the blunt needle is moved backward. When the inner needle head 8 punctures, the liquid medicine will not flow out from the original inclined plane of the sharp needle, but flow out from the first side holes 9. The design of the first side holes 9 changes the direction and speed of the drug flow. When the drug flows out from the first side holes 9, its flow direction is perpendicular to the main axis of the injection needle. This flow mode makes the drug easier to form a wide distribution area under the skin or in the tissue, rather than flowing directly towards the blood vessel, reducing the occurrence of the liquid medicine entering the blood vessel.

[0032] And a conical hopper 19 is arranged inside the inner needle head 8. The size of the discharge port of the conical hopper 19 is smaller than that of the feed port. A flow dividing plate 20 is arranged at the bottom end inside the inner needle head 8. When the liquid medicine enters the inner needle head 8, the liquid medicine is gathered through the conical hopper 19, so that all the liquid medicine falls to the upper side of the flow dividing plate 20, and the flow dividing plate 20 is used to divide the liquid medicine to promote the discharge of the liquid medicine.

[0033] Among them, in order to keep the inner needle head 8 sharp when continuously puncturing the rubber stopper of the liquid medicine container, a second needle sleeve 10 is sleeved outside the first needle sleeve 2. An outer needle head 11 is arranged at the lower end of the second needle sleeve 10. The outer needle head 11 is sleeved outside the inner needle head 8. The rubber stopper is punctured by the outer needle head 11, and then the liquid medicine is sucked into the syringe 1. When puncturing the patient, after removing the second needle sleeve 10 and the outer needle head 11, the liquid medicine can be pushed into the inner needle head 8 through the syringe 1.

[0034] Therefore, in order to fix the second needle sleeve 10, symmetrical straight grooves 3 are opened on the outer wall of the first needle sleeve 2, and an annular groove 4 is opened on the upper side of the outer wall of the first needle sleeve 2. The annular groove 4 is connected to the straight groove 3. Symmetrical first sliding blocks 14 are arranged on the inner side of the second needle sleeve 10. The first sliding blocks 14 are slidably connected with the straight grooves 3 and the annular groove 4. When the outer needle head 11 and the second needle sleeve 10 are sleeved outside the inner needle head 8, the first sliding blocks 14 slide through the straight grooves 3 to the communication part of the annular groove 4 and the straight groove 3. At this time, rotate the second needle sleeve 10 to make the first sliding blocks 14 rotate into the annular groove 4. At this time, the second needle sleeve 10 can be fixed outside the first needle sleeve 2.

[0035] Furthermore, a jack 15 is opened on one side of the first sliding block 14, and symmetrical fixing blocks 6 are arranged in the annular groove 4. An inserting block 7 is arranged on one side of the fixing block 6. When the second needle sleeve 10 rotates, the fixing block 6 rotates accordingly, so that the inserting block 7 is inserted and matched with the jack 15, further improving the stability of the second needle sleeve 10.

[0036] Secondly, an extension sleeve 5 is provided on the outer side of the first needle sleeve 2. An installation groove is formed between the extension sleeve 5 and the first needle sleeve 2. The second needle sleeve 10 is located in the installation groove. At the same time, a rotating ring 16 is provided on the outer side of the second needle sleeve 10. Symmetric sliding grooves 13 are formed on the outer wall of the second needle sleeve 10. Symmetric second sliding blocks 18 are provided on the inner side of the rotating ring 16. Since the second sliding blocks 18 are slidably connected to the sliding grooves 13, the rotating ring 16 is restricted by the sliding grooves 13. When the rotating ring 16 is rotated, the rotating ring 16 drives the second needle sleeve 10 to rotate.

[0037] At the same time, a fastening sleeve 17 is provided on the upper side of the rotating ring 16. The fastening sleeve 17 is located outside the extension sleeve 5. Therefore, after the second needle sleeve 10 enters the installation groove, the rotating ring 16 is slid upward so that the fastening sleeve 17 is sleeved on the extension sleeve 5, further improving the stability of the second needle sleeve 10.

[0038] And since a second side hole 12 is formed on the outer side of the outer needle 11, the first side hole 9 and the second side hole 12 are in corresponding positions. And a sealing ring 21 is provided at the bottom of the outer needle 11. The sealing ring 21 is located above the first side hole 9. The space between the outer needle 11 and the inner needle 8 above the first side hole 9 is sealed by the sealing ring 21. When the outer needle 11 aspirates the liquid medicine, the liquid medicine enters the first side hole 9 through the second side hole 12 and then enters the syringe 1.

[0039] In summary, the working principle of a structure of an anti-puncture beauty needle according to an embodiment of the present invention is as follows: After the outer needle 11 punctures the liquid medicine bottle, the syringe 1 is used to aspirate the liquid medicine. Through the sealing of the sealing ring 21, the liquid medicine enters the first side hole 9 from the second side hole 12. When the liquid medicine completely enters the syringe 1, the rotating ring 16 is slid downward so that the fastening sleeve 17 is separated from the extension sleeve 5. At this time, the second needle sleeve 10 is rotated to separate the insertion block 7 from the insertion hole 15. When the first sliding block 14 rotates to the position where the straight groove 3 communicates with the annular groove 4, the second needle sleeve 10 is slid downward, and the second needle sleeve 10 and the outer needle 11 can be removed from the first needle sleeve 2 and the inner needle 8. At this time, the inner needle 8 with a solid tip at the puncture end can be used for puncture.

[0040] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
