Description
Technical Field
[0001] A hydrodermabrasion needle device belongs to the technical field of beauty instruments. Background Art
[0002] The hydrodermabrasion needle is a common beauty instrument. A number of steel needles are led out inside it. When in use, the required beauty liquid medicine (such as hyaluronic acid) is injected into the dermis layer close to the epidermis through the steel needles by a special hydrodermabrasion gun. At present, multi-needle hydrodermabrasion needles are commonly used in the market to replace single-needle hydrodermabrasion needles. The structure of the multi-needle hydrodermabrasion needle includes a housing and a needle column, and the steel needles are led out from the corresponding needle columns. In actual use, since the medicine is injected into the dermis layer, if the depth of the needle piercing into the skin is small, part of the liquid medicine will overflow from the skin during the injection process. And since the steel needles are led out from the needle columns, and the needle columns are generally close to the skin surface to form a relatively sealed state, the liquid medicine overflowing from the skin will enter the inner cavity of the guide sleeve needle column through the gap between the steel needles and the needle columns. Since the price of beauty injections is generally high, during the injection process, once the situation of liquid medicine backflow occurs, it is not easy to be discovered by beauticians, resulting in waste of the liquid medicine and causing certain economic losses to beauticians. Therefore, designing a technical solution to avoid the backflow of the liquid medicine after overflow has become an urgent problem to be solved in this field. Content of the Utility Model

[0015] Figures 1 - 2 This is the best embodiment of the utility model. The following further describes the utility model in conjunction with the attached Figures 1 - 2 drawings.
[0016] As Figures 1 - 2 shown, a hydrodermabrasion needle device (hereinafter referred to as the hydrodermabrasion needle) includes a guide sleeve 10 and a lifting ring 1 clamped at the upper end of the guide sleeve 10. The guide sleeve 10 has a hollow structure, and the lifting ring 1 is rotatably clamped at the upper port of the guide sleeve 10.
[0017] A negative pressure tube 3 is radially arranged at the lower part of the guide sleeve 10, and the inner port of the negative pressure tube 3 penetrates through the guide sleeve 10 and communicates with the negative pressure cavity 15. When necessary, after being connected to the negative pressure tube 3 through an external pipeline and performing a vacuum pumping operation, a negative pressure state is formed in the negative pressure cavity 15 so that the hydrodermabrasion needle can be adsorbed on the skin surface.
[0018] A plurality of needle columns 14 are axially protruded at the lower part of the guide sleeve. The lower port of the needle column 14 is slightly higher than the lower port of the guide sleeve 10, so that the whole needle column 14 is located in the negative pressure cavity 15. The needle columns 14 can be arranged in multiple numbers according to actual needs. In this hydrodermabrasion needle, 9 needle columns 14 are arranged, and a steel needle 9 is respectively led out from each needle column 14.
[0019] A channel seat 2 is led out from the top center of the self-lifting ring 1. The channel seat 2 includes a channel tube and a chassis coaxially arranged at the bottom of the channel tube. An axially penetrating liquid inlet channel 4 is arranged at the axis of the channel seat 2. A threaded seat 5 is prominently arranged at the center of the upper surface of the lifting ring 1. An internal thread is provided on the inner wall of the threaded seat 5. The channel tube of the channel seat 2 penetrates axially along the lifting ring 1. An external thread is provided on the outer wall of the channel tube in the channel seat 2. The external thread on the surface of the channel tube is threadedly connected with the internal thread on the inner wall of the threaded seat 5.
[0020] A clamping platform is prominently arranged in the middle of the inner cavity of the guide sleeve 10. A fixing sleeve 8 is arranged above the clamping platform. The chassis of the channel seat 2 enters the inside of the fixing sleeve 8 from the upper surface of the fixing sleeve 8, and the channel seat 2 is fixedly connected with the fixing sleeve 8. When the lifting ring 1 is rotated, due to the threaded connection relationship between the threaded seat 5 and the channel seat 2, the channel seat 2 and the fixing sleeve 8 rise or fall in the guide sleeve 10.
[0021] A groove is opened upward on the lower surface of the chassis of the channel seat 2. The outer periphery of the lower surface of the chassis of the channel seat 2 is hermetically fixed to the fixing sleeve 8. A liquid inlet cavity 6 is formed at an interval between the groove on the lower surface of the chassis of the channel seat 2 and the upper surface of the fixing sleeve 8. A plurality of needle cavities 7 are axially penetrated on the surface of the fixing sleeve 8. All the needle cavities 7 are located inside the liquid inlet cavity 6. The upper port of the needle cavity 7 is communicated with the liquid inlet cavity 6. A steel needle 9 is respectively arranged in each needle cavity 7.
[0022] In the inner cavity of the guide sleeve 10, a sealing member is further arranged. The sealing member is located between the fixing sleeve 8 and the above-mentioned needle column 14. The sealing member includes a flat sealing disc 11. A plurality of sealing tubes 13 are arranged on the lower surface of the sealing disc 11. A sealing cavity 12 is axially opened in each sealing tube 13. The sealing cavity 12 penetrates through the sealing disc and the corresponding sealing tube 13 up and down. The fixing sleeve 8 is always in interference fit with the sealing disc 11 during the lifting process and is in a sealed state.
[0023] The number and relative arrangement positions of the sealing tubes 13 correspond to the above-mentioned needle columns 14 one by one. The sealing tubes 13 in the sealing member enter the inside of the corresponding needle columns 14 one by one, and the lower end of the sealing tube 13 extends to the bottom of the inner cavity of the needle column 14. A seal is formed between the sealing tube 13 and the needle column 14.
[0024] The number of the sealing tubes 13 also corresponds to the needle cavities 7 arranged in the fixing sleeve 8 one by one. After the steel needle 9 installed in the needle cavity 7 is led out from the bottom of the fixing sleeve 8, it enters the corresponding sealing tube 13 of the sealing member, and after being led out along the sealing cavity 12 from the sealing tube 13, the needle head of the steel needle 9 is led out from the bottom of the needle column 14. During the process of the steel needle 9 penetrating through the sealing cavity 12, it is simultaneously sealed with the inner wall of the sealing tube 13.
[0025] The specific working process and working principle are as follows:
[0026] Before injection, relative rotation occurs between the lifting ring 1 and the guide sleeve 10. Since the channel seat 2 is threadedly connected to the lifting ring 1, when the lifting ring 1 rotates, the channel seat 2 will move up and down within the guide sleeve 10. Since the channel seat 2 is coaxially fixed with the fixed sleeve 8 and a number of steel needles 9 are fixed within the fixed sleeve 8, adjusting the lifting ring 1 realizes the adjustment of the length of the steel needles 9 extending outside the needle column 14.
[0027] During use, after this hydro - needle is attached to the human skin surface, the tips of the steel needles 9 will pierce the human skin surface. The liquid medicine (such as hyaluronic acid) enters through the liquid inlet channel 4, then flows through the liquid inlet channel 4 into the liquid inlet cavity 6, and then enters each needle body cavity 7 on the surface of the fixed sleeve 8 through the liquid inlet cavity 6. Since the upper ends of the steel needles 9 are located at the upper ends of the needle body cavities 7, the liquid medicine will enter the steel needles 9 and flow out from the needles of the steel needles 9 and into the human body.
[0028] When the liquid medicine is injected into the human skin, if the needle length is short, part of the liquid medicine will overflow from the injection holes on the human surface. In this hydro - needle, since it is sealed through the sealing tube 13 within the needle column 14, the liquid medicine overflowing from the human skin will not flow back along the gap between the steel needles 9 and the needle column 14 into the inner cavity of the needle column 14, thus avoiding waste of the liquid medicine.
[0029] The above - mentioned are only the preferred embodiments of the present utility model, and are not limitations to the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
