Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable injection positioner. Background Technology

[0002] The endocrine system is a humoral regulatory system composed of endocrine glands and endocrine tissues and cells located in certain organs. Its main function is to release hormones under the control of the nervous system and based on metabolic feedback, regulating vital phenomena such as growth, development, reproduction, metabolism, movement, pathology, and aging, and maintaining the relative stability of the internal environment. Endocrine diseases occur due to pathological changes in endocrine glands and tissues, and many diseases can also affect the structure and function of the endocrine system through metabolic disorders.

[0003] Currently, for endocrinology patients undergoing treatment, the imbalance of various hormones in their bodies due to endocrine system disorders, such as excesses or deficiencies of certain hormones (e.g., in diabetic patients), makes treatment a long and complex process requiring continuous medication injections to restore hormonal balance.

[0004] For diabetic patients, regular insulin injections are necessary. While patients can hold an insulin pen to inject, the process requires coordination of both hands. For example, one hand uses the thumb, index, and middle fingers to lift the skin while the other hand injects the insulin. However, hemiplegic patients cannot perform this operation with one hand. Furthermore, most patients cannot control the pressure applied when injecting into their abdomen with their fingers, leading to skin whitening or pain. This can also cause the subcutaneous muscle and tissue to be pinched together, resulting in insulin mistakenly entering the muscle layer during injection. Consequently, the insulin absorption curve will not match the blood glucose absorption peak, leading to large fluctuations in blood glucose levels. Therefore, we propose an adjustable injection locator. Summary of the Invention

Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please see Figure 1-8 10-13, This invention provides a technical solution:

[0055] Example 1

[0056] An adjustable injection positioner includes a support frame 1, a movable hole at the center of the support frame 1, and a support sleeve 2 slidably connected to the movable hole. The support sleeve 2 is used to support the syringe, and a fixing member 3 is provided at the top of the support sleeve 2 for fixing the syringe.

[0057] The fastener 3 includes two grooves 21 provided on the support sleeve 2, and the two grooves 21 communicate with the through hole inside the support sleeve 2;

[0058] A fixing block 22 is slidably connected inside the groove 21. The fixing block 22 is L-shaped and has a pushing block 23 extending to the top of the support sleeve 2. The syringe has a slot on the outside corresponding to the two fixing blocks 22.

[0059] A buffer spring 24 is fixedly connected between the fixing block 22 and the groove 21.

[0060] The specific connection process between the syringe and the support sleeve 2 is as follows: First, insert one end of the syringe into the support sleeve 2. At this time, the buffer springs 24 in the two grooves 21 are in a compressed state. After placement, rotate the syringe so that its slot is aligned with the position of the two fixing blocks 22, thereby fixing the syringe. When it is necessary to remove the syringe, push the push block 23 to make the fixing block 22 deviate from the slot, so that the syringe can be quickly removed.

[0061] The support frame 1 is provided with a pushing mechanism 8, and the pushing mechanism 8 pushes the support sleeve 2 to quickly insert the syringe needle into the patient's skin. The pushing mechanism 8 includes a connecting seat 81 fixedly installed on one side of the top of the support sleeve 2. A swing rod 82 is rotatably connected to the connecting seat 81. A rotating rod 83 is rotatably connected to the top of the swing rod 82 through a pin. A rotating shaft is fixedly connected to the bottom of the rotating rod 83.

[0062] A fixed frame 84 is fixedly connected to the top of the support frame 1, and a rotating motor 85 is installed on the fixed frame 84. The output end of the rotating motor 85 is fixedly connected to the rotating shaft. Thus, the rotating shaft is driven to rotate by the operation of the rotating motor 85. When the rotating shaft rotates, it drives the rotating rod 83 to rotate synchronously. One end of the rotating rod 83 drives the swing rod 82 to swing to a certain extent through the pin. Since the support sleeve 2 is limited by the moving hole, the support sleeve 2 is further driven to move downward relative to the moving hole synchronously.

[0063] A guide mechanism 4 is provided on the top of the support frame 1 and on the side away from the push mechanism 8. The guide mechanism 4 provides secondary support for the syringe and pushes the syringe start button after the syringe needle is inserted into the patient's skin.

[0064] The guide mechanism 4 includes a handheld frame 41 fixedly mounted on the support frame 1, and a switch is installed on the handheld frame 41. The handheld frame 41 has multiple recessed positions, thereby increasing the friction of the handheld frame 41 and making it easier for the hand to grip the handheld frame 41. An extension shell 42 is fixedly connected to the top of the handheld frame 41. One end of the extension shell 42 is connected to a guide sleeve 43, and the guide sleeve 43 is slidably sleeved on the outside of the syringe.

[0065] The guide sleeve 43 is provided with a detection element 44 for detecting the position of the syringe. The detection element 44 includes a guide ring 441 fixedly installed at the bottom of the guide sleeve 43, and the guide ring 441 is slidably sleeved on the outside of the syringe. A first pressure sensor 442 is installed on the top of the guide ring 441, and a contact ring 443 is provided on the syringe near the control button.

[0066] An actuating element 45 for pushing the syringe control button is provided at the extension shell 42. The actuating element 45 includes a push rod 451 that slides through the extension shell 42 once. One end of the push rod 451 passes through the extension shell 42 and is fixedly connected to a wedge block 452. The button on the top of the syringe is conical.

[0067] The push rod 451 is slidably connected to the extension shell 42. A compression spring 453 is sleeved on the outside of the push rod 451. One end of the compression spring 453 is fixedly connected to the inner wall of the extension shell 42, and the other end of the compression spring 453 is fixedly connected to a positioning block 454. The positioning block 454 is fixedly sleeved on the outside of the push rod 451.

[0068] The positioning block 454 has a positioning hole at the bottom, and the extension shell 42 has a limiting member 46 for limiting the positioning block 454 inside. The limiting member 46 includes an electromagnet 461 fixedly installed inside the extension shell 42, and a plastic spring 462 is installed on the top of the electromagnet 461.

[0069] The top of the plastic spring 462 is fixedly connected to an iron column 463, and the top of the iron column 463 is engaged with the positioning hole. The bottom of the iron column 463 is fixedly connected to a limit block, and the inside of the extension shell 42 is provided with a limit groove for limiting the limit block.

[0070] At the bottom of the support frame 1 and at the bottom of the support sleeve 2, there is a protective component 5 for protecting the needle of the syringe during positioning. The protective component 5 includes two protective shells 51 respectively sleeved on the outside of the syringe needle. In addition, a pressure sensor is set at the bottom of the protective shell 51 so that the protective shell 51 can detect the position of the needle relative to the skin. When the pressure value of the pressure sensor at the bottom of the protective shell 51 increases, the skin is squeezed at the bottom of the protective shell 51, and the first pinch plate 61 and the second pinch plate stop operating. The top of the two protective shells 51 and the side away from each other are respectively fixedly connected to the connecting frame 52.

[0071] One end of the connecting frame 52 is fixedly connected to a connecting block 53. Two side blocks 54 are fixedly connected to the outside of the connecting block 53, and a guide rod 55 slides through the inside of the side block 54. The ends of the two sets of guide frames that are far apart from each other are set in an inclined shape, so that when the connecting block 53 moves along the guide rod 55, the connecting block 53 can move upward relative to the connecting sleeve 57, thereby allowing the protective shell 51 to move laterally relative to the support frame 1 and move upward at the same time, so as to avoid the protective shell 51 from contacting the patient's skin and affecting the injection. The bottom of the support frame 1 is provided with a base plate 56 for supporting the guide rod 55.

[0072] A connecting sleeve 57 is slidably sleeved on the outside of the connecting block 53, and the connecting sleeve 57 is provided with a groove corresponding to the position of the two guide rods 55.

[0073] The support frame 1 has two movable slots at the bottom, and a movable component 58 for moving the connecting sleeve 57 is installed inside the movable slot. The movable component 58 is a mechanism for driving the connecting sleeve 57. In this application, the movable component 58 is preferably a miniature push rod 584. The connecting sleeve 57 moves relative to the movable slot by running the miniature push rod 584.

[0074] A skin pinching mechanism 6 is provided at the bottom of the support frame 1 and outside the support sleeve 2. Before injection, the skin pinching mechanism 6 pinches the patient's skin and subcutaneous tissue to assist the syringe injection. The skin pinching mechanism 6 includes a first skin pinching plate 61 and a second skin pinching plate 62 provided outside the bottom of the syringe needle.

[0075] The first pinching plate 61 is in the shape of an arc-shaped T, and the second pinching plate 62 is in the shape of an arc-shaped U. In this application, the first pinching plate 61 is in the shape of an arc-shaped T, which imitates the human thumb, while the second pinching plate 62 is in the shape of an arc-shaped U, which imitates the shape of the human index and middle fingers. This design avoids pinching the skin with a large area of ​​the plate, which would cause the patient's muscles and subcutaneous tissue to be pinched at the same time. Through the first pinching plate 61 and the second pinching plate 62, and under the action of multiple second pressure sensors 63, the appropriate pinching force is further ensured, avoiding the phenomenon of skin whitening or pain in the patient. At the same time, it ensures precise pinching of the patient's subcutaneous tissue, effectively improving the safety of injection.

[0076] The bottom and inner side of the first skin-pinching plate 61 and the second skin-pinching plate 62 are provided with receiving grooves, and the second pressure sensor 63 is installed inside the receiving groove. The second pressure sensor 63 is provided with a contact pad on the outside and is in the center. The first skin-pinching plate 61 and the second skin-pinching plate 62 are provided with a protective pad, which can play a role in protecting the patient's skin.

[0077] The top of the first pinch plate 61 and the second pinch plate 62 are both fixedly connected to a synchronization plate 64, and both ends of the top of the synchronization plate 64 are fixedly connected to an electric push rod 65.

[0078] Each of the four electric push rods 65 has a synchronizing block 66 fixedly connected to its top. The bottom of the support frame 1 is provided with a connecting groove for limiting the four synchronizing blocks 66. The connecting groove is provided with a driving component 67 for relative movement of the first pinch plate 61 and the second pinch plate 62. The driving component 67 is rotatably connected to a bidirectional threaded screw inside the connecting groove. One end of each of the two bidirectional threaded screws is fixedly connected to a synchronizing gear. A gear chain is connected between the two synchronizing gears. A drive motor for driving one of the bidirectional threaded screws is installed inside the connecting groove. The four synchronizing blocks 66 are threaded onto the outside of the two bidirectional threaded screws. The drive motors further drive the two bidirectional threaded screws to rotate synchronously and provide the four synchronizing blocks 66 with driving forces in opposite directions. This further adjusts the distance between the first pinch plate 61 and the second pinch plate 62.

[0079] The skin-pinching mechanism 6 is provided with a support mechanism 7 on its outer side. The support mechanism 7 is used to support the support frame 1 and assist in the positioning of the syringe. The support mechanism 7 includes two telescopic rods 71 ​​fixedly installed at the bottom of the support frame 1. The telescopic rods 71 ​​are sliding rods and sliding sleeves. At the same time, a telescopic spring is installed inside the sliding sleeve. A pressure sensor can also be provided between the telescopic spring and the sliding sleeve. A buzzer is provided on the support frame 1 to avoid excessive pressure of the suction cup 72 on the human skin. The suction cup 72 is fixedly installed at the bottom of the telescopic rod 71.

[0080] Specific implementation process: When using the syringe, first place the adjusted syringe in the support sleeve 2 and fix the syringe through the support sleeve 2. At the same time, the guide ring 441 and the guide rail sleeve are positioned for secondary positioning. Then, the patient holds the hand holder 41 and places the support holder 1 at the position to be injected, while pressing down with a certain pressure to fix the two suction cups 72 to the patient's skin. Then, by pressing the switch, the first pinch plate 61 and the second pinch plate 62 move towards each other. At the same time, under the action of multiple second pressure sensors 63, when the pressure sensor detects a large pressure value, the corresponding electric push rod 65 is extended and retracted. The first pinch plate 61 and the second pinch plate 62 move towards each other, pinching the patient's skin and subcutaneous tissue.

[0081] Subsequently, the moving part 58 operates, further moving the two protective shells 51 away from each other along the syringe needle. Simultaneously, the two protective shells 51 move upward relative to the support frame 1, at which point the syringe needle is exposed. Then, the rotating motor 85 operates, further moving the support sleeve 2 downward via the rotating rod 83 and the swing rod 82, allowing the syringe needle to be quickly and completely inserted into the patient's subcutaneous tissue. At this point, the position of the syringe contact ring 443 moves to the guide ring 441 and contacts the first pressure sensor 442. Furthermore, the electromagnet 461 is energized, causing the iron rod 463 to disengage from the positioning hole. At this time, the reverse elastic force of the compression spring 453 further causes the push rod 451 to drive the wedge block 452 to move along the inside of the guide sleeve 43. At the same time, the wedge block 452 contacts the conical control button on the top of the syringe and squeezes the control button. At this time, insulin is injected into the subcutaneous tissue at the syringe needle. After 10 seconds, the rotating motor 85 continues to run, thereby quickly pulling out the syringe needle through the support sleeve 2, realizing the effect of injecting hormone into the patient. During this process, the patient only needs to hold the hand holder 41 to maintain relative stability, which can achieve the effect of single-person accurate injection.

[0082] Please see Figure 9 Example 2

[0083] Based on Embodiment 1: The moving part 58 includes a micro motor 581 fixedly installed inside the moving groove. The output end of the micro motor 581 is fixedly connected to a moving lead screw 582, and one end of the moving lead screw 582 is rotatably connected to the moving groove. A moving block 583 is threaded onto the outer side of the moving lead screw 582, and the moving block 583 is slidably connected inside the moving groove. A connecting sleeve 57 is fixedly installed at the bottom of the moving block 583. Furthermore, the micro motor 581 operates, thereby causing the moving lead screw 582 to rotate inside the moving groove. When the moving lead screw 582 rotates, it provides driving force to the moving block 583. Under the limitation of the moving groove, the moving block 583 further drives the connecting sleeve 57 to move.
