Description

Technical Field

[0001] This application relates to the field of medical aesthetic marker technology, and more particularly to a sterile multi-segment marker for injectable medical aesthetics.

[0002] This marking pen consists of several pen tips connected sequentially along the tip direction. Each pen tip is independently sealed and has its own refill. For first-time use, simply unseal the packaging to use it as a sterile pen. After use, the segmented pen tip can be used for marking in non-sterile environments, achieving segmented use and separation of purposes. This balances sterility requirements with resource conservation, improving efficiency and safety. Background Technology

[0003] In the field of injectable aesthetic medicine, whether it's Botox (for facial slimming and wrinkle removal) or hyaluronic acid (for filling and shaping), precision is key to success. Doctors need to accurately determine the injection points, layers, and dosage based on facial anatomy, muscle distribution, fat pad location, and individual patient differences. Therefore, pre-operative skin marking is the first and essential step to ensure the precision, safety, and effectiveness of the procedure.

[0004] Before dermatological procedures such as injectable cosmetic procedures, doctors need to make precise lines on the skin using a marker pen. Current technology generally uses ordinary marker pens, which are not sterile, and the pen tip, in particular, can easily become a carrier of bacteria during repeated use. Furthermore, the sterilization process is contradictory: if marking is done before sterilization, the disinfectant may seep into or erase the markings, affecting the precision of the procedure; if sterilization is done before marking, the non-sterile pen will directly contaminate the sterilized area.

[0005] To meet infection control requirements, sterile marking pens have emerged on the market. Through ethylene oxide sterilization and individual packaging, they ensure the initial sterility of the product, solving the problem of inherent bacterial contamination in traditional marking pens. However, because the pen tip comes into contact with patients during use and can easily become a carrier of pathogens, and because each pen is relatively expensive and uses a small amount of ink per marking, it is difficult to completely eliminate the phenomenon of "multiple uses for one pen" in practice. In particular, the frequent cross-use of the same pen among different patients can transform it from a sterile tool into a source of contamination.

[0006] Therefore, the market urgently needs a marker pen solution that can maintain "complete sterility" and "make the most of resources". Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this application is to provide a sterile multi-segment marking pen for injectable cosmetic medicine, which aims to overcome the waste and cross-infection defects caused by the inability of existing marking pens to meet the "sterility requirements" and "multiple patients and multiple points of use", and to provide a multi-segment marking pen that can be exposed segment by segment as needed, is disposable after use, and has both sterility assurance and cost control.

[0008] The technical solution adopted by this application to solve the technical problem is as follows: a sterile multi-segment marking pen for injectable medical aesthetics, comprising: a plurality of pen tips, wherein the plurality of pen tips are connected sequentially along the pen tip direction to form a marking pen; The pen tip includes: a connecting ring; A connecting tube is disposed at one end of the connecting ring in the direction of the pen tip, and the connecting ring is used to sleeve and engage with the adjacent pen tip; The main body is disposed at one end of the connecting cylinder in the direction of the pen tip, and a pen refill is disposed on the main body; A sealing film is connected to the main body and wraps around the pen refill.

[0009] Furthermore, the main body includes a cone, which is coaxially arranged with the connecting cylinder, and its tip is arranged along the pen tip direction; An ink trough is disposed on the surface of the cone opposite to the cone tip and is used to hold ink. A hopper cover, which is disposed on the cone and used to cover the ink trough; The pen refill is positioned along the pen tip direction, with one end penetrating the cone and located within the ink reservoir.

[0010] Furthermore, the pen tip also includes: a pen hole, which is disposed on the cone and communicates with the ink trough, and the pen core is disposed in the pen hole; Several protrusions are respectively disposed on the inner surface of the pen hole and are used to increase the friction between the pen hole and the pen core.

[0011] Furthermore, the pen tip also includes a pen cap, which is used to fit onto the connecting cylinder located at one end in the direction of the pen tip.

[0012] Furthermore, the pen tip also includes an annular blade, which is coaxially disposed inside the pen cap and is used to cut the sealing film.

[0013] Furthermore, the pen tip also includes an extension pen barrel, which is used to engage with the connecting ring at the end opposite to the pen tip direction, and the extension pen barrel is used to extend the length of the marking pen.

[0014] Furthermore, the extended pen barrel has a pen hole: an extension rod, one end of which is engaged with the connecting ring at the end opposite to the pen tip direction; An extension tube, wherein the other end of the extension rod is slidably disposed within the extension tube; A pen clip is slidably disposed on the extension tube along the axial direction of the extension tube and connected to the extension rod, the extension rod being driven by the pen clip to slide within the extension tube.

[0015] Furthermore, each of the pen tips has an axial length of 3 centimeters, and there are five pen tips in total.

[0016] Furthermore, the pen tip also includes: a plurality of magnets, which are respectively disposed on the connecting ring and the connecting cylinder, and adjacent connecting rings and connecting cylinders are detachably connected by the plurality of magnets.

[0017] Compared with the prior art, this utility model forms a marking pen by setting several pen tips, so that a pen has multiple sealed pen refills. In actual use, new pen refills can be exposed as needed, realizing "one pen for multiple uses". Furthermore, since the ink volume of a single pen tip is small, waste can be effectively reduced.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0025] This utility model provides, for example Figures 1 to 3 The sterile multi-segment marking pen shown is designed to address the shortcomings of existing marking pens that cannot be used for multiple purposes, leading to waste.

[0026] This sterile multi-segment marking pen for injectable cosmetic procedures mainly comprises: several pen tips 100, which are connected sequentially along the pen tip direction to form a marking pen. For example... Figures 1 to 3 As shown, the pen tip 100 is oriented downwards along the pen. In actual use, the pen tip is pointed towards the patient for marking. When marking different patients, the pen tip 100 at the tip direction can be removed and discarded, or used in other scenarios where sterility is not required, and then another pen tip 100 can be exposed for use, thereby preventing the pen tip 100 from becoming a source of contamination.

[0027] The pen tip 100 includes a connecting ring 110, a connecting cylinder 120, a body portion 130, and a sealing membrane 140. The connecting cylinder 120, connecting ring 110, and body portion 130 are connected sequentially from top to bottom. The connecting ring 110 can be sleeved on adjacent pen tips 100, and the two are locked together, so that multiple connecting rings 110 can form a pen barrel for medical personnel to hold. The body portion 130 is provided with a pen refill 134, which can be exposed at the bottom of the body portion 130 for use. When the bottom pen refill 134 comes into contact with a patient, it will become contaminated. Therefore, when marking another patient, the bottom pen tip 100 can be separated from the other pen tips 100 and discarded, thereby exposing a new pen refill 134 for use. In addition, the sealing film 140 is connected to the main body 130 and wraps the pen refill 134, thereby sealing and preserving the pen refill 134 and achieving sterile packaging. Therefore, medical staff can first disinfect the patient's skin and then remove the sealing film 140 to expose the pen refill 134 at the bottom for use.

[0028] To meet infection control requirements, sterile marking pens have emerged on the market. Through ethylene oxide sterilization and individual packaging, they ensure the initial sterility of the product, solving the problem of inherent bacterial contamination in traditional marking pens. However, because the pen tip comes into contact with patients during use and can easily become a carrier of pathogens, and because each pen is relatively expensive and uses a small amount of ink per marking, it is difficult to completely eliminate the phenomenon of "multiple uses for one pen" in practice. In particular, the frequent cross-use of the same pen among different patients can transform it from a sterile tool into a source of contamination.

[0029] This invention utilizes multiple pen tips 100 to form a marking pen, allowing a single pen to contain multiple sealed pen refills 134. In practical use, new refills 134 can be exposed as needed, achieving "multi-purpose use of one pen." Multiple pen tips can be used individually, enabling segmented and independent use. After unsealing the packaging, the segmented pen can be used as a sterile pen; after use under sterile conditions, it can be used for marking in non-sterile environments, achieving segmented use, separation of purposes, and improved efficiency. Furthermore, because each pen tip 100 contains a relatively small amount of ink, waste is effectively reduced.

[0030] In some embodiments, such as Figures 2 to 3As shown, the pen tip 100 also includes a cone 131, an ink reservoir 132, a cap 133, and a refill 134. Specifically, the cone 131, ink reservoir 132, cap 133, and refill 134 are all coaxially arranged with the connecting cylinder 120. The tip of the cone 131 points downwards, and one end of the refill 134 is located at the tip of the cone 131 and protrudes downwards for marking and writing. The ink reservoir 132 is disposed on the upper surface of the cone 131 and is used to hold ink. The other end of the refill 134 penetrates the cone 131 and is located within the ink reservoir 132 to draw ink from the ink reservoir 132. The cap 133 covers the ink reservoir 132 and forms a chamber with the ink reservoir 132 to hold ink. In actual production, the pen refill 134 can be fixed to the cone 131, ink can be added to the ink reservoir 132, and finally the reservoir cover 133 can be installed and fixed by heat fusion or glue to prevent ink leakage.

[0031] In some embodiments, such as Figures 2 to 3 As shown, the pen tip 100 also includes a pen hole 135 and several protrusions 136. The pen hole 135 is disposed on and coaxially arranged on the cone 131, and communicates with the ink reservoir 132. The pen refill 134 is disposed inside the pen hole 135. Several protrusions 136 are respectively disposed on the inner surface of the pen hole 135 to increase the friction between the pen hole 135 and the pen refill 134.

[0032] In some embodiments, such as Figures 1 to 3 As shown, the pen tip 100 also includes a pen cap 200. The pen cap 200 is used to fit over the connecting sleeve 120 at the lower end to cover the sealing film 140 and the pen refill 134 at the lower end, so as to prevent the sealing film 140 and the pen refill 134 from being contaminated due to friction damage, which would affect the use.

[0033] In some embodiments, such as Figures 1 to 3 As shown, the pen tip 100 also includes an annular blade 210. The annular blade 210 is coaxially disposed within the pen cap 200 and is used to cut the sealing film 140. Specifically, as... Figures 1 to 3 As shown, the pen cap 200 has openings at both ends. The connecting sleeve 120 at the lower end is disposed in the upper opening of the pen cap 200, and the annular blade 210 is disposed in the lower opening of the pen cap 200. In actual use, the pen cap 200 can be separated from the connecting sleeve 120 at the lower end, and the sealing film 140 can be inserted into the lower opening of the pen cap 200, so that the sealing film 140 contacts the annular blade 210. During this process, the pen tip 100 can be driven to rotate relative to the pen cap 200, so that the annular blade 210 can cut the sealing film 140, exposing the pen refill 134. The annular blade 210 is preferably a serrated blade made of plastic, which is not likely to damage the cone 131, but is sufficient to cut the sealing film 140.

[0034] In some embodiments, such as Figures 1 to 3As shown, the pen tip 100 also includes an extension pen barrel 300. The extension pen barrel 300 is used to engage with the connecting ring 110 at the lower end to extend the length of the marking pen, thereby avoiding the situation where the overall length of the marking pen is too short due to the small number of pen tips 100 in the later stages of use, which would be unfavorable for medical staff to grip and write markings.

[0035] In some embodiments, such as Figures 1 to 3 As shown, the extension pen barrel 300 includes a pen hole 135, an extension rod 310, an extension tube 320, and a pen clip 330. The lower end of the extension rod 310 is engaged with the upper end connecting ring 110. The extension rod 310 is slidably disposed within the extension tube 320. The pen clip 330 passes through the extension tube 320 and is connected to the extension rod 310. When the pen clip 330 is moved, it can cause the extension rod 310 to slide within the extension tube 320, thereby enabling the pen clip 330 to fix the marker pen and control the length of the marker pen.

[0036] In some embodiments, such as Figures 1 to 3 As shown, the pen tip 100 has an axial length of 3 cm, and there are five pen tips 100.

[0037] In some embodiments, the pen tip 100 further includes: a plurality of magnets, which are respectively disposed on the connecting ring 110 and the connecting cylinder 120, and adjacent connecting rings 110 and connecting cylinders 120 are detachably connected by the plurality of magnets.

[0038] In summary, a sterile multi-segment marking pen for injectable cosmetic procedures is provided, comprising several pen tips connected sequentially along the tip direction to form a marking pen. Each pen tip includes a connecting ring, a connecting cylinder, a main body, and a sealing membrane. The connecting cylinder is located at the tip-side end of the connecting ring, and the connecting ring is used to sleeve and engage with adjacent pen tips. The main body is located at the tip-side end of the connecting cylinder, and a pen refill is provided on the main body. The sealing membrane is connected to the main body and encloses the pen refill. This invention, by setting several pen tips to form a marking pen, integrates multiple "sterile short pens" into one pen. In actual use, new pen refills can be exposed as needed. After sterile use, the disassembled pen tips can be used for marking in non-sterile situations. Operators can flexibly replace pen tips according to the usage progress, achieving "one pen for multiple uses," avoiding the waste caused by discarding the entire pen in the past, and improving operational convenience and cost-effectiveness. In addition, the snap / magnetic connection allows for manual assembly and disassembly; the pen cap has a built-in ring blade, and opening the membrane requires no additional tools. The production process only adds buckles and sealing films, without significantly increasing the cost per piece, yet achieves the high-end function of "one-stop saving and one-disposal", making it suitable for large-scale adoption in clinics and institutions.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
