Description

Technical Field

[0001] The invention belongs to the field of insulin injection, and particularly relates to a sterile insulin injection device for diabetic patients. Background Art

[0002] One of the main treatments for diabetic patients is insulin injection. In order to save costs, many diabetic patients choose to inject insulin at home. However, due to the unsterilized injection site and the fact that the elderly or those with poor eyesight cannot see the injection site clearly, even if it is disinfected, they cannot accurately inject into the disinfected site, which can easily lead to infection and abscess formation at the injection site. If diabetic patients do not control their blood sugar well, on the one hand, infectious complications are likely to occur, which will affect infection control and wound healing; on the other hand, infection and trauma can further aggravate blood sugar disorders, forming a vicious cycle and increasing the difficulty of treatment. This places high demands on diabetic patients who inject insulin by themselves, especially those who are older or have poor eyesight.

[0003] In the prior art, there is a local stem cell injection device for promoting the healing of diabetic ulcer wounds, and its patent application number is: 202310888184.9; application date: 2023.07.19; comprising: a syringe, the syringe comprising: a barrel configured to carry stem cells, a needle tube is provided at one end of the barrel, and a piston is connected to the barrel; a bending assembly, the bending assembly comprising: an end seat arranged at the same end as the protrusion; at least two moving parts restricted to move in a plane perpendicular to the axis of the barrel, each moving part comprising The end seat is movably connected to the slide seat, each slide seat is constructed with a through hole for the needle tube to pass through, and the tip of the needle tube passes through each through hole in turn and extends to the outside of the end seat; at least two transmission components, each transmission component is connected to only one moving part, each transmission component includes a moving part connected to the slide seat and a transmission part arranged on the end seat for driving the moving part to move; and at least two driving members arranged on the end seat can drive the transmission component to operate; after the needle tube passes through the through hole, the driving member can drive the transmission part to operate, forcing the moving part to move, so that the slide seat moves in a plane perpendicular to the axis of the cylinder, so that the circumference of the needle tube at least simultaneously abuts against the inner walls of the two through holes, thereby bending the needle tube. The device can insert the needle into the edge of the ulcer surface between the toes on both sides caused by diabetes, but it is not suitable for sterile insulin injection for patients. Summary of the invention

[0004] The purpose of the present invention is to provide a sterile insulin injection device for diabetic patients, which can ensure the sterile injection of insulin and avoid infection at the injection site caused by improper operation.

[0005] The object of the present invention is achieved as follows: An insulin aseptic injection device for diabetic patients includes two mounting frames symmetrically arranged left and right. On the upper part of one side of the two mounting frames close to each other, side brackets are provided. A middle bracket is arranged between the two side brackets. The left and right ends of the middle bracket are respectively connected to the corresponding side brackets through a height adjustment assembly. A movable seat that can move horizontally is arranged on the middle bracket. An injection positioning mechanism that can swing back and forth is arranged on the movable seat. A syringe is installed on the injection positioning mechanism. A plurality of horizontal connection belts are connected to the outside of the two mounting frames. The outer ends of the connection belts on the left side are fixed to a first fixing part, and the outer ends of the connection belts on the right side are fixed to a second fixing part. A hook-and-loop fastener surface and a hook-and-loop fastener mother surface are respectively arranged on the first fixing part and the second fixing part, and the hook-and-loop fastener surface and the hook-and-loop fastener mother surface are arranged corresponding to each other.

[0006] When the present invention is used, first place the syringe in the movable sleeve of the outer sleeve and fix it. Then rotate the outer sleeve to adjust it to the corresponding angle. Generally, 90-degree vertical or 45-degree inclined injection is selected. Then place the middle bracket and the two side brackets above the injection site. Then connect and fix the hook-and-loop fastener surface and the hook-and-loop fastener mother surface of the first fixing part and the second fixing part around the body. The abdomen or thigh and other parts can be selected. Finally, turn on the control switch. The red light emitting device shines on the injection site, and at the same time, the voice broadcaster broadcasts a prompt to disinfect the red light irradiated site and ensure that the needle of the syringe has been replaced. The person opens the disinfection box, takes out the disinfection cotton ball, and disinfects the injection site irradiated by the red light. If the needle is an old needle, then remove the middle bracket and the two side brackets and replace them with a new needle. After preparation, turn and open the cover, and move the limit pin or the limit bolt outwards, so that the movable sleeve drives the syringe to insert the needle into the injection site, and push the piston rod of the syringe to complete the injection of insulin. Compared with the prior art, the beneficial effects of the present invention are as follows: It can select and inject different injection points on different parts such as the abdomen and thigh, avoiding fat hyperplasia caused by frequent injection of the same part; it can select 90-degree vertical or 45-degree inclined injection according to the patient's body fat and the length of the needle. When injecting for children, thin people or using a longer needle, injecting at an angle of 45 degrees can reduce the risk of intramuscular injection and has good adaptability; it can ensure aseptic injection of insulin and avoid injection site infection caused by non-standard operation.

[0007] As a further improvement of the present invention, the mounting frame is rectangular, and at least three horizontal connection belts are connected to the outside of the mounting frame. The connection belt has elasticity. By placing the middle bracket and the two side brackets above the injection site, and then connecting and fixing the hook-and-loop fastener surface and the hook-and-loop fastener mother surface of the first fixing part and the second fixing part around the body, the fixing is completed. As a further improvement of the present invention, the side bracket is rectangular or trapezoidal. The side bracket includes a horizontal section, and support sections are provided on both the left and right sides of the horizontal section. The support sections are arranged vertically or obliquely, and mounting sleeves are provided at the lower ends of the support sections. The mounting sleeves of the two support sections are sleeved on the inner side edges of the corresponding mounting frames, and the cross-section of each side edge of the mounting frame is circular. The trapezoidal side bracket structure is more concise, and the rectangular side bracket structure is more stable.

[0008] 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 spacing is left between the bottom of the fixed panel and the mounting frame. Two symmetrically arranged positioning plates are vertically provided on the inner side of the fixed panel. The cross-section of the positioning plate is L-shaped, and the positioning plate includes a main body part and a limiting part that are perpendicular to each other. A lift seat plate that can move up and down is provided between the main body parts of the two positioning plates. The front and rear side surfaces of the lift seat plate are respectively attached to the fixed panel and the limiting part of the positioning plate. The middle bracket includes two horizontally arranged transverse mounting rods, and the two front and rear corresponding mounting rods are arranged between the two lift seat plates; the height adjustment assembly includes a mounting cylinder seat provided on the lift seat plate.

The central rod passes through the compression spring, and the central rod is movably connected to the mounting cylinder seat. A plug is vertically provided at the center of the front side of the moving pressure plate, and a through hole through which the plug can pass is opened on the lift seat plate. A row of positioning holes arranged at equal intervals from top to bottom is opened on the fixed panel corresponding to the plug. The depth of the positioning hole is less than or equal to the thickness of the fixed panel. The plug passes through the through hole and is inserted into the corresponding positioning hole. When it is necessary to adjust the height of the injection positioning mechanism, the moving pressure plate is pulled outwards through the grip head, so that the plug is separated from the positioning hole, and then the position of the lift seat plate is adjusted up and down, and then the grip head is released to insert it into the corresponding positioning hole; scale lines corresponding to each positioning hole are marked on the positioning plate, which is convenient for identifying and selecting the corresponding positioning hole. The height adjustment assembly can also select a pressing bolt that is threadedly connected to the lift seat plate. The front end of the pressing bolt passes through the lift seat plate and presses the fixed panel. Upper limit plates and lower limit plates corresponding to the lift seat plate are respectively provided between the two positioning plates, and the position of the lift seat plate can be fixed arbitrarily. Finally, the depth of the syringe needle inserted into the body is changed by adjusting the distance between the syringe and the injection site. As a further improvement of the present invention, the cross-section of the mounting rod is rectangular. The moving seat includes two rectangular mounting blocks corresponding to each other front and back. A perforation is transversely formed through the mounting block. Two mounting rods are respectively arranged through the perforations of the two mounting blocks. The perforations of the mounting blocks are arranged corresponding to the mounting rods. The mounting blocks are movably connected to the corresponding mounting rods. A pressing bolt is arranged on the outer side of each of the two mounting blocks.

The pressing bolt sequentially passes through the fixing block and the mounting block and presses the mounting rod. The pressing bolt is threadedly connected to both the fixing block and the mounting block. A left side plate and a right side plate which are symmetrical to each other are arranged between the front and rear mounting blocks. Both the left side plate and the right side plate are arranged longitudinally. After loosening the pressing bolt, the position of the mounting block can be adjusted horizontally left and right, and then rotated to make the pressing bolt press the mounting rod, so as to realize the horizontal adjustment of the position of the moving seat, and avoid lipohypertrophy caused by injecting insulin into the same part.

[0009] As a further improvement of the present invention, the injection positioning mechanism includes an outer sleeve. Side supports are arranged on both the left and right sides of the outer sleeve. A transverse rotating shaft is arranged on the outer side of the side support. The two rotating shafts respectively pass through the left side plate and the right side plate and are respectively rotatably connected to the left side plate and the right side plate. An adjusting disc is fixed at the extending end of the rotating shaft. A plurality of fixing holes are formed at the outer edge of the end face of the adjusting disc and are distributed at intervals along the circumferential direction. Locking holes are correspondingly formed on both the left side plate and the right side plate for the adjusting disc. A fixing bolt vertically passes through the corresponding fixing hole of the adjusting disc and is threadedly connected to the locking hole. Each fixing hole includes a fixing hole one located on the upper side. The included angle between the fixing hole one and the horizontal plane is 90°. Fixing holes two, three, four, and five are respectively arranged on both the left and right sides of the fixing hole one. The included angles between the fixing holes two, three, four, and five and the horizontal plane are 60°, 45°, 30°, and 0° respectively. Each fixing hole is arranged at intervals along the circumferential direction around the rotating shaft. Top marks are correspondingly arranged on both the left side plate and the right side plate above the adjusting disc. Angle marks corresponding to the fixing hole one and each of the fixing holes two, three, four, and five are arranged on the adjusting disc, which is convenient for observing the adjustment angle of the injection positioning mechanism. After loosening the fixing bolt, rotate the adjusting disc until the corresponding fixing hole rotates to the position of the top mark, and then connect the fixing bolt through the corresponding fixing hole to the locking hole, so as to adjust the injection angle position of the syringe on the outer sleeve.

[0010] As a further improvement of the present invention, a central sleeve hole is axially formed inside the outer sleeve. The central sleeve hole includes sleeve hole one, sleeve hole two, and sleeve hole three which are sequentially distributed from top to bottom and are coaxial. The diameters of sleeve hole one and sleeve hole three are both larger than that of sleeve hole two. A movable sleeve that can move up and down is arranged in sleeve hole two in a matching manner, and a syringe is installed in the movable sleeve. A guide ring is arranged on the outer periphery of the movable sleeve, and the outer diameter of the guide ring is matched with the inner diameter of sleeve hole one. The guide ring is located in sleeve hole one. A gland is provided at the upper end of the outer sleeve, and the gland is fixed to the upper end face of the outer sleeve by a plurality of countersunk screws spaced circumferentially. A ring-shaped embedding part that is coaxially arranged at the lower end of the gland and is embedded in sleeve hole one is provided. The embedding part is located between the movable sleeve and the inner wall of sleeve hole one. A compression spring sleeved on the outer periphery of the movable sleeve is arranged between the embedding part and the guide ring. Two limiting holes spaced 180° circumferentially are radially formed on the outer sleeve. The two limiting holes are located on the outer periphery of sleeve hole one. A limiting pin that can move radially or a limiting bolt connected by threads is arranged in the limiting holes. The guide ring is located above the two limiting pins or limiting bolts. The upper end of the outer sleeve is fixed with an upper end cover by a plurality of countersunk screws evenly distributed circumferentially. The upper end cover presses the gland. The upper end of the movable sleeve sequentially passes through the gland and the upper end cover and extends upward. An attracting seat is arranged inside sleeve hole three.

Then, the injection site is disinfected by taking out the disinfection cotton balls in the disinfection box 48. Then, the cover 43 is rotated to open the third sleeve hole 22c of the outer sleeve 22. Only after disinfection can the limit pin 33 or the limit bolt be moved outwards to drive the syringe 5 to move downwards through the moving sleeve 29 and pierce into the injection site.

[0037] When the present invention is in use, first place the syringe 5 into the moving sleeve 29 of the outer sleeve 22 and fix it. Then rotate the outer sleeve to adjust it to the corresponding angle. Generally, select 90-degree vertical or 45-degree inclined injection. Next, place the middle bracket 3 and the two side brackets 2 above the injection site. Then connect and fix the hook surface 9 and the loop surface 10 of the fixing part one 7 and the fixing part two 8 around the body. It can be selected to surround parts such as the abdomen or thigh. Finally, 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 irradiated site and ensure that the needle of the syringe 5 has been replaced. The operator opens the disinfection box 48, takes out the disinfection cotton ball, and disinfects the injection site irradiated by the red light. If the needle is an old needle, remove the middle bracket 3 and the two side brackets 2 and replace them with a new needle. After preparation, turn and open the cover 43, and move the limit pin 33 or the limit bolt outwards, so that the moving sleeve 29 drives the syringe 5 to insert the needle into the injection site, and push the piston rod of the syringe 5 to complete the injection of insulin. The advantages of the present invention are as follows: It can select injections at different injection points on different parts such as the abdomen and thigh, avoiding fat hyperplasia caused by frequent injections at the same part; it can select 90-degree vertical or 45-degree inclined injection according to the patient's body fat and the needle length. When injecting children, thin people or using a longer needle, inject at an inclined angle of 45 degrees, which can reduce the risk of intramuscular injection and has good adaptability; it can ensure sterile insulin injection and avoid injection site infection caused by non-standard operation.
