Description

Technical Field

[0001] This invention relates to the field of medical aesthetic auxiliary devices, specifically a chin and mandibular injection volume measuring device. Background Technology

[0002] Medical aesthetics is a branch of modern medical technology. It refers to the cosmetic procedures that use drugs, surgery, medical devices, and other medical techniques to repair and reshape a person's appearance and the shape of various parts of the body. It can be used to reshape parts such as the eyelids, nose, cheekbones, lips, and jaw angles to optimize the patient's facial contours.

[0003] When cosmetic procedures reshape the chin and jaw, hyaluronic acid is injected to improve the appearance of the chin. Cosmetic surgeons usually provide a correction plan based on the patient's chin and jaw shape, or refer to pictures (videos) of previous patients' chin and jaw corrections to obtain parameters. However, all of these procedures require manual injection of hyaluronic acid with a syringe, and the amount of hyaluronic acid injected is uncontrollable, which may even lead to cosmetic medical accidents. Therefore, a chin and jaw injection volume measuring device is proposed. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a chin and mandibular injection volume measuring device to solve the problems mentioned above regarding the uncontrollable injection of hyaluronic acid and the inability to monitor and communicate with patients in real time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a chin and mandible injection volume measuring device, comprising a U-frame, the bottom of which is connected to a base plate, and a measuring component for detecting changes in the chin and mandible installed inside the U-frame;

[0006] The measuring assembly includes two sets of arc-shaped arms rotatably mounted on the inner walls of the U-shaped frame. The two sets of arc-shaped arms are in a relatively close inclined position. The end faces of the two sets of arc-shaped arms are connected to a net bag that contacts the chin. The net bag includes multiple sets of unit nets connected in series. A second connecting joint is provided between two adjacent sets of unit nets. Two sets of silicone ropes are threaded through the multiple sets of second connecting joints. The unit nets between the two sets of second connecting joints are sleeved on the outer walls of the two sets of silicone ropes. The ends of the two sets of silicone ropes extend into the arc-shaped arms. The curved outer wall of the arc-shaped arms has a travel groove. The ends of the two sets of silicone ropes are fixed to the inner wall of the travel groove. A reference block that slides inside the travel groove is fixedly sleeved on the outer wall of the silicone rope. The outer wall of the arc-shaped arms has scale lines at the upper and lower edges of the travel groove.

[0007] As a preferred technical solution, the outer wall of the arc-shaped arm is connected to a base shaft extending into the positioning hole, the inner wall of the positioning hole is provided with a positioning hole for the base shaft to rotate, and the outer wall of the base shaft is fitted with a damping sleeve fixed to the inner wall of the positioning hole.

[0008] As a preferred technical solution, a long straight groove is provided at the contact position between the outer wall of the arc-shaped arm and the base shaft, and multiple sets of elastic plates are connected at equal intervals to the upper and lower inner walls of the long straight groove.

[0009] As a preferred technical solution, the two ends of the two sets of silicone ropes are twisted into a braided silicone strip. A positioning block is fixedly sleeved on the outer wall of the braided silicone strip near the intersection of the two sets of silicone ropes. A channel for sliding between the braided silicone strip and the positioning block is opened in the arc-shaped arm.

[0010] As a preferred technical solution, the two ends of the net are provided with a first connecting joint that connects to the end face of the arc-shaped arm, and a notch for the silicone rope to move is provided at the center of the first connecting joint.

[0011] As a preferred technical solution, the bottom of the U-frame is provided with a receiving groove, and the top of the base plate is fixed with a positioning strip that is slidably connected to the receiving groove. Elastic rubber strips are pasted on the front and rear outer walls of the positioning strip, and the inner wall of the receiving groove is provided with a groove corresponding to the position of the elastic rubber strip.

[0012] As a preferred technical solution, a constraint rectangular block is fixed on the end face of the base shaft located in the long straight groove, and a space is reserved between the end face of the elastic sheet and the inner wall of the long straight groove for the constraint rectangular block to pass through.

[0013] As a preferred technical solution, a disinfection frame assembly is installed on the front and rear surfaces of the U-frame and on the top of the base plate. The disinfection frame assembly includes a panel that is slidably disposed on the front and rear surfaces of the U-frame. Each panel has an arc-shaped light strip embedded in the side of the panel closest to the U-frame. Multiple sets of downward-sloping ultraviolet germicidal lamps are installed equidistantly in the arc-shaped light strip.

[0014] As a preferred technical solution, two sets of metal shafts are fixed between the two sets of panels. The two sets of metal shafts are located at the edge of the panels. A long straight groove is provided at the position where the panel contacts the metal shaft. Magnets for attracting the metal shaft are embedded in the upper and lower inner walls of the long straight groove.

[0015] As a preferred technical solution, each panel has a charging port at the corner of its outer wall, and the charging port is electrically connected to the arc-shaped light strip by a wire.

[0016] In summary, the present invention has the following main beneficial effects:

[0017] This invention, through its measuring components, allows for real-time, intuitive monitoring of changes in the chin and mandible during chin and mandible contouring. This facilitates communication with the patient during the procedure, ensuring a shared goal and improving patient satisfaction. Furthermore, the measuring components can be adjusted to fit the dimensions of each patient's chin and mandible, ensuring full contact with the corresponding skin and achieving high-quality chin and mandible contouring.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will now be described.

[0031] A chin and mandibular injection volume measuring device, such as Figures 1 to 7 As shown, it includes a U-frame 100, with a base plate 110 connected to the bottom of the U-frame 100, and a measuring component 200 for detecting changes in the chin and mandible installed inside the U-frame 100;

[0032] The measuring assembly 200 includes two arc-shaped arms 210 rotatably mounted on the inner walls of the U-frame 100. The two sets of arc-shaped arms 210 are in a relatively close, inclined position. The end faces of the two sets of arc-shaped arms 210 are connected to a net bag 220 that contacts the chin. The net bag 220 includes multiple sets of interconnected unit meshes 250. A second connecting joint 260 is provided between adjacent sets of unit meshes 250. Two sets of silicone ropes 270 pass through the multiple sets of second connecting joints 260. The unit meshes 250 between the two sets of second connecting joints 260 are sleeved on the two sets of silicone ropes 270. The outer wall of the silicone rope 270 has a clearance hole 261 at the position where the second connecting joint 260 contacts the silicone rope 270. The ends of the two sets of silicone ropes 270 extend into the arc-shaped arm 210. The curved outer wall of the arc-shaped arm 210 has a travel groove 213. The ends of the two sets of silicone ropes 270 are fixed to the inner wall of the travel groove 213. The outer wall of the silicone rope 270 is fixedly fitted with a reference block 290 that slides inside the travel groove 213. The outer wall of the arc-shaped arm 210 has scale lines 280 at the upper and lower edges of the travel groove 213.

[0033] A long straight groove 211 is provided at the contact position between the outer wall of the arc arm 210 and the base shaft 230. Multiple sets of elastic plates 212 are connected at equal intervals to the upper and lower inner walls of the long straight groove 211.

[0034] A constraint rectangular block 231 is fixed on the end face of the base shaft 230 located in the long straight groove 211, and a space is reserved between the end face of the elastic sheet 212 and the inner wall of the long straight groove 211 for the constraint rectangular block 231 to pass through.

[0035] When measuring a patient's chin and jaw, the device needs to be placed on a table at a height corresponding to the patient's chin and jaw. The patient then moves their head closer to the U-frame 100, with the net 220 fitted over their chin. A syringe can then be used to inject medication (such as hyaluronic acid) through the unit mesh 250. This causes the chin or jaw to deform and expand outwards against the unit mesh 250. Because a first connecting joint 240 is provided between adjacent sets of unit meshes 250, the unit mesh 250 expands outwards against the patient's chin skin. The device monitors changes in the chin and jaw in real time. The silicone cord 270 is stretched due to the expansion of the unit mesh 250, and the twisted silicone strips 272 at both ends are also stretched. This pulls the reference block 290 to move linearly within the travel groove 213. It can be compared with the scale line 280 and the injected amount can be detected in real time (the change in injected volume for each scale movement is 0.05-0.1ml. The specific amount of injection represented by each scale change can be calculated based on professional cosmetic medical data). This facilitates communication with the patient during the procedure, achieves consistent goals, and improves patient satisfaction.

[0036] When the distance between the two sets of arc arms 210 is changed, the two sets of arc arms 210 will move closer to each other and will cause the base shaft 230 to extend out of the positioning hole 120. The base shaft 230 will move in a straight line along the long straight groove 211. At this time, the base shaft 230 will squeeze the elastic sheet 212 to deform, so that the base shaft 230 passes through and enters one side of the adjacent elastic sheet 212, which is used to cooperate with the adjustment of the distance between the two sets of arc arms 210, and can meet the measurement work of different patients.

[0037] Please refer to this carefully. Figure 1 and Figure 2 The outer wall of the arc arm 210 is connected to a base shaft 230 extending into the positioning hole 120. The inner wall of the positioning hole 120 is provided with a positioning hole 120 for the base shaft 230 to rotate. The outer wall of the base shaft 230 is fitted with a damping sleeve 130 fixed to the inner wall of the positioning hole 120.

[0038] The damping sleeve 130 increases the frictional force when the base shaft 230 rotates, thereby ensuring the stability of the measuring component 200 when it is in an inclined state, and making it easier for the patient's chin to contact the net 220 for measurement.

[0039] The base shaft 230, which extends into the positioning hole 120, can be used to move the two sets of arc arms 210 closer together to change the size for different patients' mandibles.

[0040] Please refer to this carefully. Figure 6The two ends of the two sets of silicone ropes 270 are twisted into a braided silicone strip 272. A positioning block 271 is fixedly sleeved on the outer wall of the braided silicone strip 272 near the intersection of the two sets of silicone ropes 270. A channel is opened in the arc-shaped arm 210 for the braided silicone strip 272 and the positioning block 271 to slide.

[0041] The twisted silicone strip 272 increases the toughness of the silicone rope 270, preventing breakage due to frequent stretching. The positioning block 271 serves to restrain the two sets of silicone ropes 270, preventing them from rotating in opposite directions or separating and causing wear, thereby extending their service life.

[0042] Please refer to this carefully. Figure 4 The net bag 220 has a first connecting joint 240 at both ends that connects to the end face of the arc arm 210, and the first connecting joint 240 has a notch in the middle for the silicone rope 270 to move.

[0043] It can accommodate two sets of arc-shaped arms 210 to converge or expand outward, which can meet the chin and jaw size of different people. At the same time, it facilitates the outward expansion of multiple sets of unit meshes 250 to intuitively understand the changes in the skin of the corresponding part of the patient's jaw.

[0044] Please refer to this carefully. Figure 7 The bottom of the U-frame 100 is provided with a receiving groove 140, and the top of the base plate 110 is fixed with a positioning strip 111 that is slidably connected to the receiving groove 140. Elastic rubber strips are attached to the front and rear outer walls of the positioning strip 111, and the inner wall of the receiving groove 140 is provided with a groove corresponding to the position of the elastic rubber strip.

[0045] By using the base plate 110 to increase the contact area between the bottom of the U-frame 100 and the table surface, it can stably bear the weight generated during the measurement of the patient's chin and mandible;

[0046] The base plate 110 is detachable by means of receiving groove 140 and positioning strip 111 for easy storage or transportation, and the elastic rubber strip and groove increase the friction during connection to ensure a firm connection between the base plate 110 and the U frame 100.

[0047] Please refer to this carefully. Figure 2 and Figure 8 A disinfection frame assembly 150 is mounted on the front and rear surfaces of the U-frame 100 and on top of the base plate 110. The disinfection frame assembly 150 includes a panel 151 that is slidably disposed on the front and rear surfaces of the U-frame 100. Each panel 151 has an arc-shaped light strip 153 embedded in the side of the panel 151 near the U-frame 100. Multiple sets of inclined downward ultraviolet germicidal lamps are installed equidistantly in the arc-shaped light strip 153.

[0048] Two sets of metal shafts 152 are fixed between the two sets of panels 151. The two sets of metal shafts 152 are located at the edge of the panel 151. A long straight groove 101 is provided at the contact position between the panel 151 and the metal shaft 152. Magnets 102 for attracting the metal shaft 152 are embedded in the upper and lower inner walls of the long straight groove 101.

[0049] Each panel 151 has a charging port at the corner of its outer wall, and the charging port is electrically connected to the arc-shaped light strip 153 by a wire.

[0050] When the measuring component 200 is not in operation, the hand applies an upward force to the two panels 151, causing them to slide upward in a straight line on the front and rear surfaces of the U-frame 100. At this time, the metal shaft 152 slides upward in the straight groove 101, and the state of the metal shaft 152 being attracted to the lower magnet 102 changes to being attracted to the upper magnet 102, causing the panel 151 to rise and be fixed. At this time, the two panels 152 and the inner wall of the U-frame 100 measuring component 200 are in a semi-enclosed state. The ultraviolet lamp inside the arc-shaped light strip 153 irradiates the net bag 220 with ultraviolet light, which can achieve the purpose of disinfection and sterilization.

[0051] By inserting a Type-C data cable into the charging port on the outer surface of panel 151, the arc-shaped light strip 153 can be driven to perform sterilization, thereby improving the hygiene of the measuring component 200.

[0052] In use, the device is placed on a table at a height corresponding to the patient's chin and jaw. The patient then moves their head closer to the U-frame 100, with the net 220 fitted over their chin. A syringe can then be used to inject medication (such as hyaluronic acid) through the unit mesh 250. This causes the chin or jaw to deform and expand outwards against the unit mesh 250. Because a first connecting joint 240 is provided between adjacent sets of unit meshes 250, the unit mesh 250 expands outwards against the patient's chin skin, allowing for real-time monitoring of changes in the chin and jaw. The silicone rope 270 will... As the unit mesh 250 expands outward and is stretched, the twisted silicone strips 272 at both ends are also stretched, which pulls the reference block 290 to move linearly within the stroke groove 213. This allows for comparison with the scale line 280 and real-time detection of the injected volume (the change in injected volume for each scale step is 0.05-0.1 ml; the specific amount of injection represented by each scale step can be calculated based on professional cosmetic medical data). This facilitates communication with the patient during the procedure, achieving a consistent goal and improving patient satisfaction. Any parts of the device not involved are the same as or can be implemented using existing technologies.
