Description

Technical Field

[0001] The present invention generally relates to syringes (infusion devices) for injecting drugs into living organisms.

[0002] In particular, the present invention is needed for first aid and emergency intervention for oneself or others; the present invention relates to a magnetic autoinjector for use in situations requiring intradermal, subcutaneous or intramuscular injection into a living body and provides safe and easy use. Background Technology

[0003] Today, syringes are used in situations requiring intradermal, subcutaneous, or intramuscular injection of drugs into a living organism. In its most common form, a syringe includes a tube filled with the drug to be injected, a needle that allows the drug to be transferred to the living organism, and a propellant element that allows the drug to be propelled.

[0004] In the existing technology, syringes with different designs and operating methods have been developed to meet various needs. Autoinjectors are one type of syringe. Autoinjectors are designed to deliver a specific dose of a particular drug. There are two sets of autoinjectors: those with needles and those without. The disadvantage of needle-equipped autoinjectors is that they have a complex operating principle and a standard long syringe, piston rod, and spring. The biggest disadvantage of needleless autoinjectors (jet injectors) is that they require the use of non-disposable special equipment and carry a risk of infection.

[0005] In the prior art, several documents have been found concerning syringes. Document WO2014162439A1 relates to a pistonless infusion syringe, which is easy to carry and designed for simple injection of drug solutions. In this infusion syringe, a push structure for dispensing the drug solution using magnetic force is formed within its body. In this structure, a magnet is placed in a fixed retainer at the rear of the body, and another magnet is placed in an inner retainer that allows drug injection. The magnets are positioned within the fixed and inner retainers with their same magnetic poles facing each other, i.e., they are positioned such that the fixed and inner retainers repel each other. Simultaneously, the inner retainer is locked by a stop outside the body. Released after the stop is moved, the inner retainer moves towards the end of the body due to the mutual push of the magnets, and the drug solution is provided as it exits from the end of the body. In this embodiment, the magnets only provide dispensing of liquid from the infusion syringe, while the user provides the infusion needle to enter the skin. Meanwhile, the syringe needle is located outside the syringe body and is fixed. With this structure, the aforementioned syringe configuration cannot provide quick, easy, and safe usability.

[0006] Document EP3338833B1 relates to an autoinjector. In this document, a spring-loaded actuation mechanism is used to expel liquid drug substances present in the infusion unit. The actuation of this spring mechanism is provided by a mechanical trigger button located outside the syringe. In this embodiment, the piston movement of the syringe and the insertion of the needle into the skin are provided by the spring mechanism. The size of the spring mechanism used affects the size of the syringe body. Furthermore, the needle, exiting the syringe body, remains external. In this state, the aforementioned structure cannot be smaller than a certain size, and leaving the needle outside is disadvantageous from a safety perspective.

[0007] Therefore, improvements to the syringe are needed, requiring a new structure that will eliminate the aforementioned drawbacks and provide a solution for existing systems. Summary of the Invention

[0008] The present invention relates to a magnetic auto-injector that meets the above requirements, eliminates all disadvantages, and provides some additional advantages.

[0009] The main objective of this invention is to ensure that a certain dose of drug is automatically injected into a living body via intradermal, subcutaneous, or intramuscular injection.

[0010] The object of this invention is to ensure the automated execution of the injection process using a structure that eliminates the need for a piston rod and spring mechanism. This invention aims to introduce a shorter and smaller syringe than existing technologies by eliminating the use of a piston rod and spring mechanism.

[0011] To achieve all the above advantages, and as will be understood from the following detailed description, the present invention is a magnetic autoinjector for use in situations requiring intradermal, subcutaneous, or intramuscular injection into a living organism, allowing for the easy and safe injection of a dose of liquid medication into the living organism; therefore, the magnetic autoinjector has a structure comprising the following:

[0012] • The syringe body is in the form of a closed cylinder and has an outlet opening located at the end.

[0013] • A fixed magnet, having an inlet opening thereon and positioned within the syringe body, primarily in the center of the syringe body.

[0014] • A needle magnet having a needle located thereon and positioned in the syringe body between a fixed magnet and an outlet opening, close to the fixed magnet, wherein the same magnetic poles of the needle magnet and the fixed magnet face each other to ensure that the needle magnet and the fixed magnet exert a repulsive force.

[0015] • A piston magnet, positioned within the syringe body on the opposite side of a fixed magnet, wherein the opposite magnetic poles of the piston magnet and the fixed magnet face each other to ensure that the piston magnet and the fixed magnet exert a pulling force on each other, and wherein liquid medication is present between the piston magnet and the fixed magnet.

[0016] • Transfer channel, located inside the stationary magnet and needle magnet, provides a transfer channel for liquid medication entering through the inlet opening to the needle.

[0017] • Locking element that holds the piston magnet and needle magnet in place against pulling and pushing forces when the syringe is not in use.

[0018] The structure and features of the invention, and all its advantages, will be more clearly understood with the aid of the accompanying drawings and the detailed description written with reference to these drawings. For this reason, an evaluation should be made by considering these drawings and the detailed explanation. Attached Figure Description

[0031] In this detailed explanation, the preferred embodiments of the magnetic auto-injector according to the invention are provided only for a better understanding of the subject matter and are not intended to be limiting.

[0032] This invention relates to a magnetic autoinjector for use in situations requiring intradermal, subcutaneous, or intramuscular injection into a living organism, allowing for the easy and safe injection of a specific dose of liquid medication into the living body; the magnetic autoinjector comprises:

[0033] • Syringe body (1), which has a closed cylindrical shape and an outlet opening (9) located at the end,

[0034] • A fixed magnet (3), which has an inlet opening (8) and is fixedly positioned in the syringe body (1), mainly in the middle region of the syringe body (1).

[0035] • Needle magnet (4) having a needle (5) thereon and positioned in the syringe body (1) between the fixed magnet (3) and the outlet opening (9), close to the fixed magnet (3) and wherein the same magnetic poles of the needle magnet and the fixed magnet face each other so that the needle magnet and the fixed magnet can exert a repulsive force.

[0036] • A piston magnet (2) is located inside the syringe body (1) on the other side of a fixed magnet (3), wherein the opposite magnetic poles of the piston magnet and the fixed magnet face each other to provide a pulling force to each other, and wherein there is liquid drug between the piston magnet and the fixed magnet.

[0037] • Transfer channel (6), located inside the stationary magnet (3) and the needle magnet (4), provides for the transfer of liquid medication entering through the inlet opening (8) to the needle (5).

[0038] • Locking element (7) which fixes the piston magnet (2) and needle magnet (4) against pulling and pushing forces when the syringe is not in use.

[0039] exist Figure 1The image shows an overall view of a magnetic injector, the subject of this invention. In its most common form, the magnetic auto-injector includes a syringe body (1), a piston magnet (2), a stationary magnet (3), and a needle magnet (4) connected to a needle (5) positioned within the syringe body (1). The syringe body (1) has a cylindrical structure similar to that of a conventional syringe and includes an outlet opening (9) at its tip allowing the needle (5) to exit. The piston magnet (2), stationary magnet (3), and needle magnet (4) are also positioned within the syringe body (1) according to the form of the syringe body (1). The piston magnet (1) provides actuation of liquid medication within the syringe body (1) and between the piston magnet (2) and the stationary magnet (3). The needle magnet (4) carries the needle (5) and provides movement of the needle (5). The stationary magnet (2) is located in the middle of the syringe body (1) and provides movement of the piston magnet (2) and the needle magnet (4). To achieve this, the opposite magnetic poles of the piston magnet (2) and the fixed magnet (3) face each other, and the same magnetic poles of the needle magnet (4) and the fixed magnet (3) face each other. In this state, the fixed magnet (3) pulls the piston magnet (2) towards itself while pushing the needle magnet (4), causing the needle (5) to emerge from the outlet opening (9). Simultaneously, a transfer channel (6) exists through the fixed magnet (3) and the needle magnet (4) to ensure that the liquid drug between the piston magnet (2) and the fixed magnet (3) is pushed to the needle (5). After the liquid drug is pushed, it enters through the inlet opening (8) on the fixed magnet (3) and reaches the needle (5) via the transfer channel (6). The transfer channel (6) has a flexible and extendable structure to ensure the movement of the needle magnet (4) toward the outlet opening (9).

[0040] The syringe body (1) contains a locking element (7) to ensure that the piston magnet (2) and needle magnet (4) remain fixed when the magnetic auto-injector is not in use. The locking element (7) locks the piston magnet (2) in the pulling direction and the needle magnet (4) in the pushing direction. In this way, it is ensured that liquid medication is not delivered to the needle (5) when the syringe is not in use, and that the needle (5) remains inside the syringe body (1).

[0041] The preferred embodiment of the present invention operates as follows:

[0042] Currently, the piston magnet (2) and needle magnet (4) in the magnetic autoinjector are locked by a locking element (7). Liquid medication exists between the piston magnet (2) and the stationary magnet (3). When it is desired to inject the liquid medication into a living organism, the locking element (7) is first triggered, releasing the piston magnet (2) and needle magnet (4). The released piston magnet (2) is attracted by the stationary magnet (3); the needle magnet (4) is pushed by the stationary magnet (3). During this movement, the liquid medication between the piston magnet (2) and the stationary magnet (3) enters through the inlet opening (8) on the stationary magnet (3) and moves towards the needle (5) via the transfer channel (6). The needle magnet (4) also moves towards the outlet opening (9) through the flexible structure of the transfer channel (6), ensuring that the needle (5) exits from the outlet opening (9) and reaches the living organism. Due to this movement, the piston magnet (2) contacts the fixed magnet (3), and the liquid drug between the piston magnet and the fixed magnet reaches the needle (5) through the transfer channel (6) and is injected into the living body.

[0043] After the injection process, the needle (5) is pressed against a hard surface and the needle magnet (4) is brought to its initial position. To achieve this, the surface of the locking element (7) facing the outlet opening (9) is angled. The needle magnet (4) opens the locking element (7) by pushing against the angled surface of the locking element (7), and locks again when the needle magnet (4) reaches the upper part of the locking element (7). In this way, it is ensured that the needle (5) remains in the syringe body (1) so that the needle will not pierce again.
