Description

Technical Field

[0001] The present invention relates to the medical field, and in particular to a simulation training tool in the form of a medical simulator, which can be used in the field of cosmetology to gain experience and professional skills in lip surgery intervention. Background Art

[0002] The simulation method is one of the modern technologies for teaching and assessing practical skills, based on the modeling of real, non-computerized situations on real simulators, without harming the patient, allowing for the performance of a variety of practical training skills. For example, an anatomically accurate and highly realistic simulator for practicing congenital cleft lip correction is known (https: / / virtumed.ru / fantomy-simulyatory / hirurgicheskie-fantomy / fantom-zayachej-guby.html

[0003] ). Chinese patent publication number CN210925155U describes a simulator for cleft lip surgery. The simulator "Performing intravenous injection and blood drawing" is well known in veterinary medicine. The simulator is a full-color panel on which four skin areas and subcutaneous layer simulators are mounted. It is intended to practice skills for two types of medical procedures: intravenous injection and blood sampling under different conditions of vascular access. For intravenous injection, modules with different vein depths and modules with different types of veins have been developed: simulated standard access veins, simulated central access veins. Similar two modules are provided for practicing blood drawing skills. The process is controlled by the outflow of a liquid simulating blood in the case of an injection, or by seeing the same liquid simulating blood falling into the syringe during blood collection. The skin simulator material visually and tactilely imitates animal skin (https: / / labstand.ru / catalog / laboratornye-stendy-i-trenazhery-po-veterinarii / trenazher-provedenie-vnutrivennyh-inekczij-i-zabor-krovi).

[0004] One of the earliest simulators used to practice injections into different parts of the body, introducing subcutaneous, intradermal and intramuscular injection techniques, was a special pad. They usually consist of several layers of tissue, simulating the epidermis, dermis, fat and muscle layers.

[0006] Lip aesthetics is a rapidly growing and popular segment of corrective medicine that involves changes in aesthetic and physical features related to increasing proportion, volume, correcting asymmetry, highlighting lip contours, wrinkles around the lips, and generally rejuvenating the area around the mouth. The main method of correction is the injection of corrective volumizing agents (fillers), primarily based on hyaluronic acid, directly into the lips or perioral area.

[0007] There are many injection techniques that can achieve the desired results, however, the frequency of errors in these procedures remains high, which requires the search for new ways to train specialists using interactive and highly realistic simulation devices. However, to date, there has been no simulator that allows the injection of real lips and the simultaneous visualization of the injection results on the simulator's lips. There are only computer phantoms and monolithic fixed lip models made of polymer. Summary of the invention

[0008] The technical problem to be solved by the present invention is to develop a simulation beauty simulator for practicing injection technique skills and the results obtained by lip contouring techniques.

[0009] This problem is solved by the proposed simulator. The cosmetology simulator for practicing lip contouring skills consists of a rigid plastic skeleton with teeth on the inside of the skeleton located in an oral simulation and an elastic aesthetic shell made of a soft elastomer placed on the skeleton. The elastic aesthetic shell includes an upper lip and a lower lip with an opening therebetween. The vertical depression (Philtrum) of the skin between the base of the nasal septum and the upper lip has an inner cavity filled with a polymer composition, the density of which allows the introduction of an additional volume of injectable drugs. Both the upper and lower lips are equipped with upper and lower lip artery simulators in the form of a metal conductor located at a depth of 3-7 mm in the midline of the lips and connected in series with a controller and a piezoelectric radiator mounted on the outside of the skeleton equipped with a power connector.

DETAILED DESCRIPTION

[0016] The simulator skeleton with the necessary cavities is made by polymer casting using a mold or a 3D printer. The skeleton material can be any suitable thermoelastic, such as PVC, polystyrene, silicone or polylactide (PLA), preferably light-colored. The aesthetic upper shell is made by liquid elastomer injection molding, using two compression molds: the mold of the perioral part of the face is filled with a polymer composition with a Shore A00 hardness, and then the molding compression mold is inserted into it. The molding compression mold is made in the form of a model to reproduce the geometry of the aesthetic part of the simulator's face. The color of the aesthetic shell can be different, but usually, a natural color close to the facial area is selected by adding appropriate dyes suitable for the polymer used to the polymer composition. After the compression mold is extracted, the vertical depression of the skin between the base of the nasal septum and the upper lip (Philtrum) and the cavity of the lips are filled with a polymer composition with a Shore A hardness of less than 0 to ensure the necessary shape and density of the lips, thereby allowing the introduction of an additional volume of injectable drugs (fillers) during the contouring process. Next, the arterial simulation is installed in the lip cavity, and the two ends of the metal arterial simulation are extended outside. The lip cavity is sealed. The resulting upper polymer aesthetic shell is placed on the frame.

[0017] The skeleton 1 is equipped with an electronic unit mounted outside the skeleton, namely a microcontroller 5 (e.g. from the company Arduino Nano) and a piezoelectric radiator 6. The two ends of the upper and lower artificial arteries (9, 10) are connected to the microcontroller and the piezoelectric radiator. From the outside, the skeleton can be closed with a cover with a power supply connector.

[0018] The elastic aesthetic shell can be made of a suitable soft elastomer, such as platinum-based silicone (density 1.07 g / cm 3 , Shore hardness A00), such as Silic Pig (shiny tone).

[0019] For fillers of the lip cavities (7, 8) and the vertical depression of the skin between the base of the nasal septum and the upper lip (Philtrum), a two-component mixture of silicones selected experimentally with a Shore hardness A less than 0 can be used, in which the ratio of A to B is equal to 2.5:1, which is actually close to natural lips, allowing the introduction of additional volumes of injectable drugs. For example, in order to obtain such a composition, a two-component mixture of brands such as MOLD, Quatro silico, JYS E100, etc. can be used as the initial mixture of silicone. In order to create realistic lip filler bruises during the simulation, for example, GorkyLiquid Reactive (blood-blood) photopolymer resin can be added to the composition, which does not inhibit the polymerization of silicone fillers. The position of the artery simulator is at a depth of 3-7 mm, corresponding to its anatomical location.

[0020] The simulator trainer of the present application was created to practice the skills of lip contouring by introducing filler directly into the silicone lips and into the vertical depression of the skin (Philtrum) between the base of the nasal septum and the upper lip during the contouring process. This enables the performance of various injection techniques. To use the trainer, first connect it to a power source. When inserting the needle using the chosen injection technique, the doctor should not touch the artery simulator located in the lip (conductor), otherwise interference will be generated in the circuit. The microcontroller analyzes the interference and, if it exceeds the allowed level, sends a signal to the piezoelectric radiator, which produces a harsh sound. The current and voltage are extremely small and cannot be felt by humans.
