DETAILED DESCRIPTION OF THE INVENTION This detailed explanation of the invention is solely for the purpose of providing a better understanding of the subject. and is explained with examples that will not create any limiting effects. 20 The invention relates to vaccination, needling or injection procedures as shown in Figures 1-4. configured for use; at least one injector body (10), injector body (10) At least one injector connection area (11) on the injector body (10) at least one needle (20) in contact with and to secure the needle (20) after use at least one injector assembly containing at least one protective element (21) arranged in such way 25 It is related to (1). The syringe body (10) contains the drug, vaccine or similar fluid substance to be injected. It creates an inner chamber into which the needle can be placed. The syringe body attaches to the needle. The distal end of the eye can be directly connected to the needle (20) or via a needle connector. It is structured in such a way that it can be connected. The injector body (10) is known to be 30 The invention allows syringes to perform both fluid intake and fluid administration functions. This includes modifying the internal working mechanism of the injector body. It is not necessary. The injector connection area (11) is located on the outer surface of the injector body (10). created and the protective element (21) in its position before use temporary 5 It is the area that allows it to be fixed. The injector connection area (11), protective It differs from the area where the element is permanently attached to the injector body and is only temporary protection of the protective element to maintain its pre-use position. It is used in establishing the connection. The injector connection area, injector on the cylindrical outer lateral surface of its body and 10 degrees backwards of the protective element It can be positioned to align with the free end in the rotated state. The needle (20) is attached directly to the distal end of the syringe body (10) or via a needle connection. connects via a segment and penetrates the relevant tissue during the injection process. It is a pointed element. The protective element (21) protects the needle of the injector assembly (1). (20) It protects and does not have a needle or needle hub on it. 15 The length and cross-sectional dimensions of the needle channel (23) and the channel of the retaining claws (231) distribution throughout, to different lengths and diameters within a defined compatibility range. the needles are accepted into the canal and secured by at least one retaining claw. It can be arranged in a way that allows it to be held in place. Thus, the same protective layer The element geometry is compatible with 20 different needle types within the given compatibility range. It can be used. However, for needles or syringes that fall outside the compatibility range: Protective elements of different sizes using the same structural principle It can be created. Protective element (21); at least one protective housing (22), protective housing (22) At least one needle channel (23) created on (22), inside needle channel (23) at least one retaining claw (231) found, at least one 25 associated with each retaining claw (231) formwork opening (232), at least one extended stabilization zone (24), at least one It includes a connecting tongue (25) and at least one temporary fixing zone (26). Protective body, needle channel, retaining lugs, extended stabilization zone, connecting tongue The temporary fixation area is preferably produced in a single mold and as a monolithic unit. Thus, a separate assembly process is required between the sub-regions of the protective element. 30 It is not necessary to carry it out. The protective element (21), the needle (20) or the connection of the needle to the injector body (10) a standalone protective module that does not contain a pin connector 6 It is in the form of a protective element (21), the needle (20) of the injector assembly (1). It does not form a replacement needle unit; it is connected to the injector body (10). This ensures the preservation of the existing needle (20) after use. the protective element is produced separately while being integrated with different needle types It is not needed. 5 Protective element (21), preferably made of polypropylene, which is flexible, moldable and a polymer material that has properties that can withstand sterilization processes It can be manufactured. However, the protective element is suitable for use in medical devices. biocompatible and various thermoplastics that can provide the necessary flexibility and mechanical strength. It can also be produced from materials. The cross-section in different regions of the protective element is 10 Their thicknesses differ depending on the function that the regions in question will perform. It can be defined as follows: Specifically, the part of the connecting tongue that is desired to be flexible should be the protective layer. to be thinner, narrower, or more flexible compared to other parts of the body It can be produced. The protective housing (22) should be removed from the needle (20) before use. a movable main part located and rotated towards the needle after injection It is the body section. The protective body protects at least the pointed tip of the needle and preferably... long enough to accommodate the portion of the needle that extends along the needle shaft The length, width and depth of the protective body (22) are regulated. Needles within the specified compatibility range, at least the pointed ends, and preferably needle 20 It is designed to completely surround their bodies. Protective body (22), size for different needle lengths within the said compatibility range It may have a standard geometry that can be used without modification. Alternatively The dimensions of the protective casing in the designs are different for different needle groups. Adaptable. The protective casing, when returned to the protective position after use, is 25. leaving the needle exposed and making it come into contact with the user or other people in the vicinity It prevents. The needle channel (23) runs along the protective housing (22) and into the needle (20). It creates an internal opening in which the needle can be inserted. The needle channel is the protective barrier for the needle. The element must be able to enter the channel laterally during its rotational movement, at least 30 It is structured with only one side open. The needle channel is U-shaped, C-shaped, an angular, curved, or other cross-section suitable for containing a needle It may have a specific geometry. The open side of the channel, the protective element towards the needle. 7 so that when rotated, it will encounter the path of movement of the needle. It is being redirected. The inner width and depth of the needle channel (23) allow the needle (20) to enter the channel. It will deliver the needle, but in the protective position it will prevent the needle from moving out of the channel. It is determined as follows. The needle channel is located along the longitudinal axis of the protective housing 5 It can extend linearly along its length, as well as adapt to different needle geometries. It may also have a partially inclined or stepped structure in order to provide this. The canal The open portion facing the needle is designed to facilitate the guidance of the needle into the canal. They may include extended entry surfaces or guiding surfaces. The retaining tab (231) extends 10 from the side wall of the needle channel (23) into the inner opening of the channel. It is an extending, sloping, and preferably elastically flexible projection. Gripping nail, needle. (20) as a result of the force applied by the needle when entering the canal, the canal wall It flexes correctly and allows the needle to pass through the nail and advance into the inner part of the canal. It provides this. After the needle passes through the claw, the retaining claw utilizes the elastic properties of the material. thanks to this, it returns to its starting position and the needle remains open in the channel 15 It forms a mechanical barrier that prevents it from escaping. Locking of the protective element in the final protection position by the retaining tabs (231) This is achieved as a result of this one-way interaction with the needle (20). The extended stabilization zone (24) with the injector body (10) or needle It is not mandatory to have an additional locking connection between the connection parts. 20 After the needle passes through the retaining tab and is placed in the needle channel (23), the protective The body (22) is moved in the opposite direction to the needle, from the protective position. It cannot be removed. In a preferred configuration, three needles are placed spaced along the needle channel (23). A retaining claw (231) can be found. However, the number of claws is not limiting and can be one, 25 Two, three, four, or more retaining tabs can be used. The retaining tabs must be the same. It can be located on the side wall, or alternatively, on opposite sides in different configurations. on the walls, alternately on different side walls or in the needle channel They can be arranged so that they extend from the base towards the inner opening. The angle of inclination of the nails, Length, thickness, and tensile strength, along with the force of needle entry into and exit from the canal (30 This can be determined by considering the resistance shown against its removal. Mold opening (232), during the production of the protective element of the relevant retaining tab (231). Protective housing (22) to give passage to the mold core which enables shaping. 8 It is created on it. A separate mold opening for each retaining tab. The mold openings are aligned with the retaining tabs or the relevant mold core. It can be arranged in an adjacent location that will allow access to the nail. This configuration, protective retaining tabs that form an inverted angle or undersection within the needle channel It allows the element to be molded in a monolithic way and the product to be removed from the mold. 5 It provides. The extended stabilization zone (24) connects the protective housing (22) to the injector body. (10) formed in the near part and a wider cross-section than the needle channel (23). It is the area that has. Extended stabilization zone, protective body needle (20) When brought over, the distal part of the syringe body facing the needle should be at least 10 It is arranged to partially surround the area. This region is semi-cylindrical, U-shaped, curved or having another inner surface that conforms to the outer geometry of the injector body it could be. Extended stabilization zone (24), protective housing (22) relative to the needle (20) It helps in alignment and the lateral 15 of the protective housing in the protection position. It restricts its movement. Also, the entry part of the needle channel (23) and the needle are the same by ensuring the needle remains outside the channel, thus meeting in the direction of movement. It reduces the possibility of the extended stabilization zone (24) being open and injector The structure that surrounds only partially the body (10) of the injector of the region in question It does not require a perfect circumferential match with the body. Therefore, the same 20 extended stabilization zone geometry, different diameters within a defined range. It can be used with injector bodies. Extended stabilization zone (24), different Flexible side walls to accommodate different body diameters, stepped interior surfaces. or may include intermittent support surfaces in contact with the body. Compatibility range For injector bodies outside the main body, the dimensions of this section can be changed. This section is 25 It is not necessary for the injector body to be additionally clamped or locked. The connecting tongue (25) is formed as a single unit with the protective element (21) and the protective It is an extension that enables the element to be permanently attached to the injector body (10). The connecting tongue is a protective housing (22) with an end part fixed to the injector body. It includes a flexible section that allows it to rotate. Therefore, the protective 30 The element needs to have a hinge separate from the connecting tongue. It is not audible. The flexible part of the connecting tongue, the protective housing and the injector body. It creates an integrated rotation and bending zone between them. 9 The connecting tongue (25) is the cylindrical outer side of the injector body (10) facing the needle. It is permanently bonded to the surface. The connecting tongue is preferably attached to the injector body. It can be fixed with ultrasonic welding. In alternative structures, the permanent structure in question... Connection methods include thermal welding, laser welding, bonding, mechanical clamping, and tight fitting. 5 using interlocking joints, figural joints or a combination thereof. This can be achieved. The connection method involves rotating the protective element and temporary the separation of the connecting tongue from the injector body during disconnection It must be strong enough to withstand the impact. The protective element (21) is connected to the injector body (10) via the connecting tongue (25) permanent connection, during the manufacture of the injector assembly and preferably by sterilization 10 It is formed before the final packaging processes. The protective element. Due to its connection to the outer surface of the injector body, the injector body's reservoir, Modifications are needed in the piston and fluid delivery systems. It is not heard. Thus, protective measures are applied to the traditional injector production infrastructure. A safety injector 15 is made by adding an assembly step for connecting the element. The device can be obtained. The flexibility of the connecting tongue (25) is relative to the protective element (21) to the injector body (10). It enables rotation. The protective element forms on the flexible part of the connecting tongue. Movement via bending between pre-use position and storage position. This movement is being performed. This movement may preferably include a turn of approximately 180 degrees. 20 However, the angle of rotation of the protective element on the injector body different values ​​depending on placement, injector size and needle length it could be. The temporary fixing area (26) is located away from the connecting tongue (25) of the protective element (21). It is created in the free end section. Protective element usage 25 before being moved away from the needle (20) and onto the body of the syringe (10). When reversed, the temporary fixing area, the injector connection area (11) They are positioned opposite each other: the temporary fixing area and the injector connection area. The temporary connection created between them, the protective element along the injector body It keeps it in a stable position, extending outwards. 30 In this pre-use position, the protective element (21) is used for vaccination, injection or from the needle in such a way as not to prevent the use of the needle (20) during the injection procedure It is kept at a distance. Temporary connection, protective element transport, sterilization, spontaneously during packaging, unpacking and injection processes It is designed to be strong enough to prevent it from moving or swaying. Protective element (21), temporary fixing area in pre-use position (26) sterilized by means of fixing on the injector body (10) and It can be packaged. The syringe body (10), needle (20) and protective element (21) are the same 5 It forms a complete, ready-to-use unit within the packaging. The user needs to separate it. to provide a protective needle unit, to open a second package, or It is necessary to attach a protective piece to the injector before injection. It is not audible. The temporary fixation area (26) is preferably ultrasonicated to the injector connection area (11). It connects via a temporary resource interface created with the resource. (The word...) The subject is a point source, a source with a limited surface area, low an energized source or another source structure with controlled separation resistance This can be implemented as follows. In alternative configurations, temporary connections, thermal sources, Controlled bonding, removable adhesive, friction-on, snap-on, clip-on 15 The connection can be achieved through a formal connection or another detachable mechanical connection. The connection between the temporary fixing area (26) and the injector connection area (11), the pulling or lifting force applied by the user to the protective element (21) As a result, it disconnects from the connection interface. During this disconnection, the protective mechanism... The element, temporary fixation area and injector body do not disintegrate and the protective 20 structural damage that prevents the element from fulfilling its function of protecting the needle It does not occur. In other words, separation occurs in the body of the protective element. No, the source that creates the temporary link, the paste or the formal link It takes place on the interface. The separation resistance of the temporary connection is 25° to the connection tongue (25) to the injector body (10). It is determined that the resistance of the permanent linkage will be lower than the separation resistance. Therefore, when the user applies force to disconnect the temporary connection, it first The temporary connection interface is detached, and the connection tongue is attached to the injector body. remains. The separation resistance of the temporary connection is also present during normal transport. Unintentional separation under sterilization, packaging and handling forces 30 It is selected at a level that will prevent this. During the use of the injector assembly (1), the protective element (21) is first applied to the injector. turned back onto the body (10) and the temporary fixation area (26) 11 It is connected to the injector connection area (11) via this. The needle (20) is exposed in a way that is suitable for performing the injection procedure. and is available for use. After the injection process is complete, the user, Temporary connection by applying tensile or lifting force to the protective element. It separates the interface. 5 The protective element (21) that is released by the separation of the temporary connection, the connection tongue (25) is rotated towards the needle (20) using its flexibility. The protective element extended stabilization zone (24) during turning, protective body (22) It ensures alignment with respect to the distal part of the injector body. Rotation Continuing its movement, the needle is inserted into the canal from the open side of the needle channel (23) 10 It enters and overcomes at least one of the retaining claws (231). After the retaining tab (231) of the needle (20) passes through, the tab opens the channel of the needle. It returns to its position, preventing it from coming back out. Thus, it is protective. The body (22) is held irreversibly on the needle and the pointed end of the needle The needle channel (23) is protected within it. Final protection and locking, 15 This protection is achieved through the mechanical interaction between the retaining claw and the needle. Another part of the element needs to be locked separately to the injector body. It is not audible. Attaching the protective element (21) to the outer surface of the injector body (10). Thanks to the injector body's drug reservoir, piston structure, heat and fluid transfer mechanism 20 The safety feature can be added without modification. The protective element is monolithic. production reduces the number of parts and assembly complexity, while before use The temporary fixation prevents the protective element from interfering with the injection process. The one-way prong structure after use prevents the needle from being exposed again. By preventing accidental needle sticks, it reduces the risk of injury. 25 Protective element (21), a single standard within a defined compatibility range. with geometry, injector bodies of different volumes (10) and different lengths or It can be arranged to be applied to needles with diameters (20). In this configuration The length of the needle channel (23) is the compatibility range of the pointed ends of the needles will surround, the cross-section of the needle channel will accept different needle diameters and channel 30 At least one of the spaced retaining tabs (231) along the length of the needle must be irreversibly removed.
