Description

Technical Field

[0001] This invention belongs to the field of insulin injection, and specifically relates to a sterile insulin injection device for diabetic patients. Background Technology

[0002] Insulin injection is a primary treatment for diabetes. To save costs, many diabetic patients choose to inject insulin at home. However, problems such as unsterilized injection sites, difficulty seeing the injection site due to age, or inaccurate injection even after sterilization can easily lead to infection and abscess formation. Poor blood sugar control in diabetic patients can easily lead to infectious complications, affecting infection control and wound healing. Furthermore, infection and trauma can further aggravate blood sugar imbalances, creating a vicious cycle that increases the difficulty of treatment. This places high demands on self-injecting insulin, especially for older or visually impaired diabetic patients.

[0003] In the prior art, there is a stem cell local injection device for promoting the healing of diabetic ulcers, patent application number: 202310888184.9; application date: 2023.07.19; comprising: a syringe, the syringe including: a cylinder configured to carry stem cells, one end of the cylinder having a needle tube, and a piston connected to the cylinder; a bending assembly, the bending assembly including: an end seat disposed at the same end as the protrusion; at least two movable parts constrained to move in a plane perpendicular to the axis of the cylinder, each movable part including a...

[0004] The device comprises a sliding block movably connected to an end seat, each block having a through-hole for the needle to pass through. The tip of the needle passes through each through-hole sequentially and extends to the outside of the end seat. It includes at least two transmission assemblies, each connected to only one moving part. Each transmission assembly includes a moving part connected to the sliding block and a transmission part on the end seat for moving the moving part. It also includes at least two driving members on the end seat to drive the transmission assemblies. When the needle passes through the through-hole, the driving members drive the transmission part, forcing the moving part to move, causing the sliding block to move in a plane perpendicular to the cylinder axis. This causes the circumference of the needle to simultaneously abut against the inner walls of at least two through-holes, thus bending the needle. This device can insert the needle into the edge of ulcers between the toes caused by diabetes, but it is not suitable for aseptic insulin injection. Summary of the Invention

[0005] The purpose of this invention is to provide a sterile insulin injection device for diabetic patients, which can ensure sterile insulin injection and avoid infection at the injection site due to improper operation.

[0006] The objective of this invention is achieved as follows: A sterile insulin injection device for diabetic patients includes two symmetrically arranged mounting frames. Each mounting frame has a side support on its upper part on one side closest to the other. A central support is positioned between the two side supports. The left and right ends of the central support are connected to the corresponding side supports via height adjustment components. A laterally movable seat is provided on the central support, and an injection positioning mechanism that can swing back and forth is provided on the movable seat. A syringe is mounted on the injection positioning mechanism. Several transverse connecting straps are connected to the outer sides of both mounting frames. The outward-facing end of each connecting strap on the left is fixed to a first fixing part, and the outward-facing end of each connecting strap on the right is fixed to a second fixing part. The first and second fixing parts are respectively provided with a hook and loop fastener front surface and a hook and loop fastener back surface, which are arranged correspondingly to each other.

[0007] When using this invention, first place the syringe into the movable sleeve of the outer sleeve and fix it in place. Then, rotate the outer sleeve to adjust it to the appropriate angle, generally 90 degrees vertical or 45 degrees tilted for injection. Next, place the central support and the two side supports above the injection site. Then, connect and fix the Velcro side and Velcro backing of the fixing part one and fixing part two around the body, such as around the abdomen or thigh. Finally, turn on the control switch, and the red light emitting device shines on the injection site. At the same time, the voice broadcast will announce that the red light irradiated area should be disinfected and that the syringe needle has been replaced. The person opens the disinfection box, takes out a disinfectant cotton ball, and disinfects the injection site irradiated by the red light. If the needle is an old needle, remove the central support and the two side supports and replace it with a new needle. After preparation, rotate the cover to open it and move the limiting pin or limiting bolt outward, so that the movable sleeve drives the syringe to insert the needle into the injection site, pushing the piston rod of the syringe to complete the insulin injection. Compared with the prior art, the beneficial effects of the present invention are as follows: it can select different injection points in different parts of the body, such as the abdomen and thighs, to avoid fat hyperplasia caused by frequent injections in the same area; it can select 90-degree vertical or 45-degree tilted injection according to the patient's weight and needle length. For children, thin people, or when using longer needles, 45-degree tilted injection can reduce the risk of intramuscular injection and has good adaptability; it can ensure sterile insulin injection and avoid infection at the injection site due to improper operation.

[0008] As a further improvement of the present invention, the mounting frame is rectangular, and at least three transverse connecting straps are connected to the outer side of the mounting frame. The connecting straps are elastic. Fixing is achieved by placing the central support and side supports above the injection site, and then connecting and fixing the Velcro front and back surfaces of fixing parts one and two around the body.

[0009] As a further improvement of the present invention, the side bracket is rectangular or trapezoidal, and includes a horizontal section. Support sections are provided on both the left and right sides of the horizontal section. The support sections are vertically or inclined, and mounting sleeves are provided at the lower ends of the support sections. The mounting sleeves of both support sections are fitted onto the inner sides of the corresponding mounting frames. Each side of the mounting frame has a circular cross-section. The trapezoidal side bracket structure is more streamlined, while the rectangular side bracket structure is more stable.

[0010] As a further improvement of the present invention, a vertical fixed panel is provided between the two support sections. The top of the fixed panel is fixed to the horizontal section, and a gap is left between the bottom of the fixed panel and the mounting frame. Two symmetrical positioning plates are vertically arranged on the inner side of the fixed panel. The positioning plates have an L-shaped cross-section and include mutually perpendicular main bodies and limiting parts. A vertically movable lifting seat plate is provided between the main bodies of the two positioning plates. The front and rear sides of the lifting seat plate are respectively abutted against the fixed panel and the limiting parts of the positioning plates. The central support includes two parallel horizontal mounting rods, and the two corresponding mounting rods are arranged between the two lifting seat plates. The height adjustment component includes a mounting plate arranged on the lifting seat plate. The mounting base has an internal mounting groove, inside which a circular movable pressure plate is positioned. A central rod extends outward from the center of the rear side of the movable pressure plate and has a gripping head at its extended end. The front side of the movable pressure plate rests against a lifting seat plate. A compression spring is located between the rear side of the movable pressure plate and the end face of the mounting base, through which the central rod passes. The central rod is movably connected to the mounting base. A pin is vertically positioned at the center of the front side of the movable pressure plate. The lifting seat plate has a through hole for the pin to pass through. A row of equally spaced positioning holes, corresponding to the pin, is provided on the fixed panel. The depth of each positioning hole is less than or equal to the thickness of the fixed panel. The pin passes through the through hole and inserts into the corresponding positioning hole. To adjust the height of the injection positioning mechanism, the movable pressure plate is pulled outward using the gripping head, separating the pin from the positioning hole. The position of the lifting seat plate is then adjusted by moving it up and down. The gripping head is then released to allow the pin to insert into the corresponding positioning hole. The positioning plate is marked with scale lines corresponding to each positioning hole for easy identification and selection. The height adjustment component can also use a clamping bolt that is threadedly connected to the lifting seat plate. The front end of the clamping bolt passes through the lifting seat plate and clamps the fixed panel. An upper limit plate and a lower limit plate are respectively provided between the two positioning plates corresponding to the lifting seat plate, allowing for arbitrary fixing of the lifting seat plate position. Ultimately, the depth of needle insertion into the body is changed by adjusting the distance between the syringe and the injection site.

[0011] As a further improvement of the present invention, the mounting rod has a rectangular cross-section, and the movable seat includes two rectangular mounting blocks corresponding to each other. A through hole is horizontally provided on each mounting block, and two mounting rods pass through the through holes of the two mounting blocks respectively. The through holes of the mounting blocks correspond to the mounting rods. The mounting blocks are movably connected to the corresponding mounting rods. A clamping bolt is provided on the outer side of each of the two mounting blocks, and a fixing block is provided on the outer side of each mounting block. The clamping bolt passes through the fixing block and the mounting block in sequence, clamping the mounting rods. The clamping bolt is threadedly connected to both the fixing block and the mounting block. A symmetrical left side plate and a right side plate are provided between the two mounting blocks, and both the left and right side plates are longitudinally oriented. After loosening the clamping bolt, the position of the mounting block can be adjusted horizontally left and right, and then rotated to clamp the mounting rods with the clamping bolt, thereby achieving horizontal adjustment of the movable seat position and avoiding lipomatosis caused by injecting insulin into the same area.

[0012] As a further improvement of the present invention, the injection positioning mechanism includes an outer sleeve, with side supports on both the left and right sides of the outer sleeve. A transverse rotating shaft is provided on the outer side of the side support. The two rotating shafts pass through the left side plate and the right side plate respectively and are rotatably connected to the left side plate and the right side plate respectively. An adjusting disc is fixed at the extended end of the rotating shaft. A plurality of fixing holes are provided on the outer edge of the end face of the adjusting disc at intervals along the circumference. Locking holes are provided on both the left side plate and the right side plate corresponding to the adjusting disc. Fixing bolts pass vertically through the corresponding fixing holes of the adjusting disc and are threadedly connected to the locking holes. Each fixing hole includes a fixing hole one located on the upper side, with an angle of 90° to the horizontal plane. Fixing holes two, three, four, and five are provided on both the left and right sides of fixing hole one, with angles of 60°, 45°, 30°, and 0° to the horizontal plane, respectively. The fixing holes are spaced circumferentially around the rotation axis. The left and right sides of the plate are marked with a top mark on the upper side of the adjustment disc. The adjustment disc is marked with a corresponding angle for fixing hole one and each of fixing holes two, three, four, and five, to facilitate observation of the adjustment angle of the injection positioning mechanism. After loosening the fixing bolt, rotate the adjustment disc until the corresponding fixing hole is in the position marked with a top mark. Then, pass the fixing bolt through the corresponding fixing hole and connect it to the locking hole to adjust the injection angle position of the syringe on the outer sleeve.

[0013] As a further improvement of the present invention, a central sleeve hole is provided axially inside the outer sleeve. The central sleeve hole includes three sleeve holes: sleeve hole one, sleeve hole two, and sleeve hole three, which are distributed sequentially from top to bottom and are coaxial. The diameters of sleeve hole one and sleeve hole three are both larger than the diameter of sleeve hole two. A movable sleeve that can move up and down is fitted inside sleeve hole two. The syringe is installed inside the movable sleeve. A guide ring is provided on the outer periphery of the movable sleeve. The outer diameter of the guide ring is matched with the inner diameter of sleeve hole one. The guide ring is located inside sleeve hole one. A pressure cap is provided at the upper end of the outer sleeve. The pressure cap is fixed to the upper end face of the outer sleeve by a number of countersunk screws distributed circumferentially. An annular embedding part is coaxially provided at the lower end of the pressure cap and embedded in sleeve hole one. The inlet is located between the movable sleeve and the inner wall of the sleeve hole. A compression spring is provided between the embedded part and the guide ring and sleeved on the outer circumference of the movable sleeve. Two limiting holes with a circumferential interval of 180° are opened radially on the outer sleeve. The two limiting holes are located on the outer circumference of the sleeve hole. A limiting pin that can move radially is provided in the limiting hole or a limiting bolt connected by a thread. The guide ring is located on the upper side of the two limiting pins or limiting bolts. The upper end of the outer sleeve is fixed with an upper end cover by several countersunk screws evenly distributed along the circumference. The upper end cover presses against the pressure cover. The upper end of the movable sleeve passes through the pressure cover in sequence and the upper end cover extends upward. A suction seat is provided inside the sleeve hole. A through hole for the needle of a syringe to pass through is opened in the middle of the suction seat. When installing the syringe, insert the syringe into the movable sleeve and fix the positioning ring to the movable sleeve with the fastening screw. The syringe guide bar is inserted into the guide limiting hole of the outer sleeve. When injection is needed, move the limiting pin or limiting bolt outward, and then the compression spring pushes the syringe downward. At the same time, the suction seat attracts the strong magnet at the lower end of the movable sleeve, so that the syringe needle is inserted into the body part. The guide bar is inserted into the guide limiting hole, and the guide ring moves along the first sleeve hole to guide the movement of the movable sleeve. When the guide bar moves to the lower end of the guide limiting hole and the guide ring moves to the lower end of the first sleeve hole, there is a gap between the suction seat and the strong magnet. When the elasticity of the compression spring is insufficient, the upper end cover and the pressure cover can be removed in sequence, a new compression spring can be replaced, and then the pressure cover and the upper end cover can be reinstalled.

[0014] As a further improvement of the present invention, a stop ring is fixedly provided at the lower end of the sleeve hole one of the outer sleeve. The stop ring is correspondingly provided with the guide ring. The movable sleeve is fitted through the stop ring. A circular lower baffle is provided at the lower end of the movable sleeve. The syringe is axially inserted into the movable sleeve. The lower end of the syringe barrel fits against the lower baffle. A needle hole for the syringe needle to pass through is opened in the middle of the lower baffle. A positioning ring is provided on the outer periphery of the syringe. The positioning ring is fixed to the upper end of the movable sleeve by at least two left and right symmetrical fastening screws. An outer step is provided on the upper end of the syringe barrel. At least two circumferentially distributed guide strips are provided at the lower end of the outer step. The countersunk screws on the pressure cap and the upper end cap are all circumferentially distributed. Four guide strips are evenly distributed, with each guide strip staggered from each countersunk screw. Several guide limiting holes are provided on the outer sleeve corresponding to each guide strip. Each guide strip passes downwards through the upper end cap and the pressure cap, extending into the corresponding guide limiting hole. A ring-shaped strong magnet is provided at the lower end of the lower baffle. Mounting blocks are provided on both sides of the suction seat. Vertical insertion slots are provided on both sides of the sleeve hole three on the outer sleeve, with the length of the insertion slots being less than the length of the sleeve hole three. Two mounting blocks are respectively located at the upper ends of the two insertion slots and are fixed to the outer sleeve by fasteners. The suction seat is circular and is a strong magnet. The suction seat attracts the strong magnet on the lower side of the lower baffle. The suction seat and the strong magnet are positive and negative poles of each other. When the guide ring moves to contact the stop ring, the moving sleeve descends to its position, and the syringe needle passes through the suction seat and inserts into the body.

[0015] As a further improvement of the present invention, the lower outer periphery of the outer sleeve is provided with an installation step, and a circular cover is provided corresponding to the sleeve hole three of the outer sleeve. The left and right sides of the cover are respectively provided with connecting block one and connecting block two. Connecting block one is rotatably connected to the left side of the installation step through a rotating shaft. The lower right end of the installation step is provided with a limiting protrusion. The cover is provided with a limiting groove corresponding to the limiting protrusion. The limiting protrusion is inserted into the limiting groove. The lower center of the cover is provided with a red light emitting device. The red light emitting device integrates a voice broadcaster. The red light emitted by the red light emitting device is coaxially arranged with the syringe. The connecting block two of the cover is provided with a control switch for controlling the red light emitting device and the voice broadcaster. The front part of the side bracket is provided with a disinfection box. The disinfection box is provided with an openable lid. Several disinfection cotton balls are placed inside the disinfection box. Before injection, turn on the control switch. The red light emitter will shine on the injection site, and at the same time, the voice broadcast will announce that the red light irradiation site should be disinfected and that the syringe needle has been replaced. Then, disinfect the injection site by taking out the disinfection cotton ball from the disinfection box. Next, turn the cover to open the sleeve hole three of the outer sleeve. Only after disinfection can the limit pin or limit bolt be moved outward to move the syringe downward to insert it into the injection site. Attached Figure Description

Detailed Implementation Example 1

[0035] like Figure 1-17As shown, a sterile insulin injection device for diabetic patients includes two symmetrically arranged mounting frames 1. Side supports 2 are provided on the upper part of the sides of the two mounting frames 1 that are close to each other. A central support 3 is provided between the two side supports 2. The left and right ends of the central support 3 are connected to the corresponding side supports 2 via height adjustment components. A laterally movable seat 4 is provided on the central support 3, and an injection positioning mechanism that can swing back and forth is provided on the movable seat 4. A syringe 5 is installed on the injection positioning mechanism. Several transverse connecting straps 6 are connected to the outer sides of both mounting frames 1. The outward end of each connecting strap 6 on the left is fixed to a fixing part 7, and the outward end of each connecting strap 6 on the right is fixed to a fixing part 8. A hook and loop fastener face 9 and a hook and loop fastener face 10 are respectively provided on the fixing part 7 and the fixing part 8, and the hook and loop fastener face 9 and the hook and loop fastener face 10 are arranged correspondingly to each other. The mounting frame 1 is rectangular, and at least three transverse connecting straps 6 are connected to the outer side of the mounting frame 1. The connecting strap 6 is elastic. By placing the central support 3 and the two side supports 2 above the area to be injected, and then connecting and fixing the Velcro front surface 9 and the Velcro back surface 10 of the fixing part 1 7 and the fixing part 2 8 around the body, the fixation is completed.

[0036] The side bracket 2 is rectangular and includes a horizontal section 2a. Support sections 2b are provided on both the left and right sides of the horizontal section 2a. The support sections 2b are vertically arranged, and mounting sleeves 11 are provided at their lower ends. The mounting sleeves 11 of both support sections 2b are fitted onto the inner sides of the corresponding mounting frames 1. Each side of the mounting frame 1 has a circular cross-section. The rectangular side bracket 2 has a more stable structure. A vertical fixed panel 12 is provided between the two support sections 2b. The top of the fixed panel 12 is fixed to the horizontal section 2a, and a gap is left between the bottom of the fixed panel 12 and the mounting frame 1. Two symmetrical positioning plates 13 are vertically arranged on the inner side of the fixed panel 12. The positioning plates 13 have an L-shaped cross section and include mutually perpendicular main body parts 13a and limiting parts 13b. A vertically movable lifting seat plate 14 is provided between the main body parts 13a of the two positioning plates 13. The front and rear sides of the lifting seat plate 14 are respectively attached to the fixed panel 12 and the limiting parts 13b of the positioning plates 13. The middle bracket 3 includes two parallel horizontal mounting rods 3a, and the two corresponding mounting rods 3a are arranged between the two lifting seat plates 14. The height adjustment component includes a mounting cylinder 15 arranged on the lifting seat plate 14. The mounting cylinder 15 has an opening inside. The mounting slot 15a has a corresponding circular movable pressure plate 16 inside. A central rod 16a is located at the center of the rear side of the movable pressure plate 16. The central rod 16a extends outward from the mounting cylinder 15 and has a gripping head 16b at its extended end. The front side of the movable pressure plate 16 is attached to the lifting seat plate 14. A compression spring 17 is located between the rear side of the movable pressure plate 16 and the end face of the mounting cylinder 15. The central rod 16a passes through the compression spring 17 and is movably connected to the mounting cylinder 15. A pin 18 is vertically located at the center of the front side of the movable pressure plate 16. The lifting seat plate 14 has a through hole that allows the pin 18 to pass through. A row of positioning holes 19 are arranged at equal intervals from top to bottom on the fixed panel 12 corresponding to the pin 18. The depth of the positioning holes 19 is less than or equal to the thickness of the fixed panel 12. The pin 18 passes through the through hole and is inserted into the corresponding positioning hole 19. When the height of the injection positioning mechanism needs to be adjusted, the moving pressure plate 16 is pulled outward by the gripping head 16b, causing the pin 18 to separate from the positioning hole 19. Then, the position of the lifting seat plate 14 is adjusted by moving it up and down, and the gripping head 16b is released to allow it to insert into the corresponding positioning hole 19. The positioning plate 13 is marked with scale lines corresponding to each positioning hole 19, making it easy to identify and select the corresponding positioning hole 19. The height adjustment component can also be a clamping bolt 20 that is threaded to the lifting seat plate 14. The front end of the clamping bolt 20 passes through the lifting seat plate 14 and clamps the fixing panel 12. The two positioning plates 13 are respectively provided with an upper limit plate 12a and a lower limit plate 12b corresponding to the lifting seat plate 14, which can realize arbitrary fixing of the position of the lifting seat plate 14. Finally, the depth of the needle of the syringe 5 inserted into the body is changed by adjusting the distance between the syringe 5 and the injection site.

[0037] The mounting rod 3a has a rectangular cross-section. The movable seat 4 includes two rectangular mounting blocks 401 that are corresponding to each other. A through hole is opened horizontally through the mounting block 401. The two mounting rods 3a are respectively set through the through holes of the two mounting blocks 401. The through holes of the mounting blocks 401 are corresponding to the mounting rods 3a. The mounting blocks 401 are movably connected to the corresponding mounting rods 3a. A clamping bolt 20 is set on the outer side of each of the two mounting blocks 401. A fixing block 21 is set on the outer side of the mounting blocks 401. The clamping bolt 20 passes through the fixing block 21 and the mounting block 401 in sequence and clamps the mounting rods 3a. The clamping bolt 20 is threadedly connected to the fixing block 21 and the mounting block 401. A symmetrical left side plate 402 and a right side plate 403 are set between the two mounting blocks 401. The left side plate 402 and the right side plate 403 are both set longitudinally. After loosening the clamping bolt 20, the position of the mounting block 401 can be adjusted horizontally left and right, and then rotated so that the clamping bolt 20 clamps the mounting rod 3a, thereby adjusting the position of the movable seat 4 horizontally and avoiding the injection of insulin into the same area, which could lead to fat hyperplasia.

[0038] The injection positioning mechanism includes an outer sleeve 22, with side supports 23 on both the left and right sides of the outer sleeve 22. A transverse rotating shaft 24 is provided on the outer side of the side support 23. The two rotating shafts 24 pass through the left side plate 402 and the right side plate 403 respectively and are rotatably connected to the left side plate 402 and the right side plate 403 respectively. An adjusting disc 25 is fixed to the extended end of the rotating shaft 24. Several fixing holes are provided on the outer edge of the end face of the adjusting disc 25 at intervals along the circumference. Locking holes 27 are provided on the left side plate 402 and the right side plate 403 corresponding to the adjusting disc 25. Fixing bolts 28 pass vertically through the corresponding fixing holes of the adjusting disc 25 and are threadedly connected to the locking holes 27. Each fixing hole includes a fixing hole 26a located on the upper side, with an angle of 90° to the horizontal plane. Fixing holes 26b, 26c, 26d, and 26e are provided on both sides of fixing hole 26a. The angles of fixing holes 26b, 26c, 26d, and 26e to the horizontal plane are 60°, 45°, 30°, and 0°, respectively. These fixing holes are spaced circumferentially around the rotation axis 24. Corresponding adjustment holes are also provided on the left side plate 402 and the right side plate 403. The upper side of the adjustment disc 25 is provided with a top mark 26. Each of the fixing holes 26a, 26b, 26c, 26d, and 26e on the adjustment disc 25 is provided with a corresponding angle mark, which makes it easy to observe the adjustment angle of the injection positioning mechanism. After loosening the fixing bolt 28, rotate the adjustment disc 25 until the corresponding fixing hole is in the position of the top mark 26. Then, pass the fixing bolt 28 through the corresponding fixing hole and connect it to the locking hole 27 to adjust the injection angle position of the syringe 5 on the outer sleeve 22.

[0039] The outer sleeve 22 has a central sleeve hole axially formed inside. The central sleeve hole includes three coaxially arranged sleeve holes 22a, 22b, and 22c, arranged sequentially from top to bottom. The diameters of sleeve holes 22a and 22c are larger than the diameter of sleeve hole 22b. A movable sleeve 29 that can move up and down is fitted inside sleeve hole 22b. The syringe 5 is installed inside the movable sleeve 29. A guide ring 29a is provided on the outer periphery of the movable sleeve 29. The outer diameter of the guide ring 29a matches the inner diameter of sleeve hole 22a. The guide ring 29a is located inside sleeve hole 22a. A pressure cap 30 is provided at the upper end of the outer sleeve 22. The pressure cap 30 is fixed to the upper end face of the outer sleeve 22 by several countersunk screws 35 spaced circumferentially. An annular embedding part 30a is coaxially provided at the lower end of the pressure cap 30 and is embedded in sleeve hole 22a. Between the inner walls of the movable sleeve 29 and the first sleeve hole 22a, a compression spring 31 is provided between the embedded part 30a and the guide ring 29a, which is sleeved on the outer periphery of the movable sleeve 29.

The limiting protrusion 42a is inserted into the limiting groove. Inside the slot, a red light emitting device 45 is provided at the lower center of the cover 43. A voice broadcaster 46 is integrated on the red light emitting device 45. The red light emitted by the red light emitting device 45 is coaxially arranged with the syringe 5. A control switch 47 for controlling the red light emitting device 45 and the voice broadcaster 46 is provided on the connecting block 43b of the cover 43. A disinfection box 48 is provided at the front of the side bracket 2. The disinfection box 48 is provided with an openable lid 48a. Several disinfection cotton balls are placed inside the disinfection box 48. Before injection, turn on the control switch 47, and the red light emitting device 45 shines on the injection site. At the same time, the voice broadcaster 46 broadcasts a prompt to disinfect the red light irradiation site and ensure that the needle of the syringe 5 has been replaced. Then, disinfect the injection site by taking out the disinfection cotton ball from the disinfection box 48. Next, turn the cover 43 to open the sleeve hole 22c of the outer sleeve 22. Only after disinfection can the limiting pin 33 or the limiting bolt be moved outward to move the syringe 5 downward to insert it into the injection site by moving the sleeve 29.

[0042] In use, the syringe 5 is first placed into the movable sleeve 29 of the outer sleeve 22 and fixed in place. Then, the outer sleeve is rotated and adjusted to the corresponding angle, generally 90 degrees vertical or 45 degrees tilted for injection. Next, the central support 3 and the two side supports 2 are placed above the area to be injected. Then, the Velcro surfaces 9 and 10 of the fixing parts 1 and 2 are connected and fixed around the body, such as around the abdomen or thighs. Finally, the control switch 47 is turned on, and the red light emitting device 45 shines on the area to be injected. Simultaneously, the voice announcer 46 broadcasts a message requesting disinfection of the red light irradiation area and confirmation that the needle of the syringe 5 has been replaced. Personnel open the disinfection box 48, remove a sterile cotton ball, and disinfect the injection site. If the needle is an old one, the central support 3 and the side supports 2 are removed and replaced with a new needle. Once ready, the cover 43 is rotated open, and the limiting pin 33 or limiting bolt is moved outwards, causing the moving sleeve 29 to drive the syringe 5, inserting the needle into the injection site and pushing the piston rod of the syringe 5 to complete the insulin injection. The advantages of this invention are: it allows for selective injection at different points in different areas such as the abdomen and thighs, avoiding frequent injections to the same area that could lead to fat hyperplasia; it allows for 90-degree vertical or 45-degree tilted injection depending on the patient's body size and needle length; for children, thin individuals, or when using longer needles, a 45-degree tilt reduces the risk of intramuscular injection and provides good adaptability; and it ensures aseptic insulin injection, preventing infection at the injection site due to improper operation. Example 2

[0043] like Figure 18 The difference from Embodiment 1 is that the side support 2 is trapezoidal, and the support section 2b is inclined. The trapezoidal side support 2 has a more streamlined structure.
