Product Information

The needle safety feature can also take the form of a hinged cover. The cover can be pushed down with a finger or against a hard surface so only one hand is required. The cover can be incorporated into the syringe, such as: The bevel is the slanted, sharpened edge of the needle tip that facilitates the penetration of the skin, muscle, or blood vessel. It is designed to minimize pain and tissue damage during the injection process. In addition to the geometric interface, the balance of forces between PFS and autoinjector is also critical to device performance (Figure 2). The spring rate and pre-compression must be sufficient to overcome the stopper break-loose force to initiate syringe emptying, exceed the glide force to prevent stalling and achieve the required injection time. At the upper limit, spring load is limited by available space and the maximum impact force to avoid damage to the syringe and avoid material creep in moulded parts. Although long springs with a low spring rate can seem like an ideal solution, with almost constant spring load, equilibrium spring length is limited by the challenge of compressing very long springs as part of an automated assembly process. Prefilled syringes: These syringes come preloaded with medication, ensuring accurate dosing and reducing medication errors.

Dysfunction at the interface between prefilled syringe and autoinjector? With a clear view of the critical inter-dependencies and a well-characterised syringe, it need not come to that. We have a vision of prefilled syringe and autoinjector working together in harmony, and, with good communication within and between partner organisations, we as an industry can make it happen. The needle cap should be removed immediately before use and replaced after the procedure is complete. Syringe and Sharps Disposal Safety Needle placement during manufacture and stoppering during fill and finish are both referenced to the flange, resulting in unpredictable offsets that appear as variability in critical dimensions such as the shoulder to needle-tip distance. Figure 1 shows the critical measurements from the points of view of manufacturing and device functionality.The plunger is pushed or pulled to either draw liquid into the barrel or expel it out through the needle. The seal between the plunger and the barrel is critical for maintaining airtight conditions, ensuring accuracy, and preventing leakage. 4. Thumb Rest In this bespoke service each product enquiry is personally managed from request to delivery and confirming product compatibility. Why Use SpeedSample? The bevel is the slanted, sharpened edge of the needle tip, designed to minimize pain and tissue damage during penetration. The cannula, or shaft, is the hollow, stainless steel tube forming the body of the needle, allowing for the passage of liquid. The orientation of the bevel during an injection can also influence the level of patient discomfort, with the bevel-up approach often resulting in less pain. 10. Needle Cap

Your child’s doctor, pharmacist or nurse will be able to give you more information about your child’s medicine. A clearly defined interface specification can be used to define a matched set of characterisation tests to assess compatibility between autoinjector and PFS. The development of the specification and the associated tests is a crucial learning step that should be integral to the device development process. It further comes into its own when the inevitable question is asked: “Can the device deliver a different PFS?” Whether it is a new drug product, a new syringe, or both, the interface specification provides a clear process and unambiguous answers to critical questions of compatibility.The exact specifications of your requirements are discussed between the SpeedSample team and the experienced sales team Finally, we extend the interface concept beyond purely functional considerations to include organisational challenges – dysfunction at the interfaces within and between organisations involved in selection and development of autoinjectors can mirror challenges within the device. The benefits of getting it right are far-reaching and include rapid and effective evaluation of new PFS-autoinjector pairings, improved device performance and reliability, and accelerated development timelines. Critical dimensions at the geometric interface

Note: A 2-part syringe consists of two components: the barrel and the plunger. A 3-part syringe, on the other hand, comprises three components: the barrel, the plunger, and a separate rubber or elastomeric stopper. Different species of liberty cap spores uk all look unique, and so do their spore prints. Because of this, mycologists like to study the pattern of a print to identify its species. To produce spore syringes or vials for microscopy, they can also be suspended in a solution. Identifying mushrooms with microscopy is simple. It is also a really fun hobby! Psilocybe cubensis – A Sacred Mushroom! The choice of mounting location and geometry defines many aspects of the final assembled device, including critical requirements such as injection depth. The syringe shoulder is created by forming semi-molten glass over a tungsten pin, in a process that inevitably results in a highly variable geometry, although this can be mitigated by post-forming inspection. To make matters worse, although all manufacturers comply with the ISO-specified dimensions, varying processes can still result in different nominal geometries.The part of a syringe that should never be touched is the needle, specifically the needle tip. Touching the needle can compromise its sterility and increase the risk of infection or contamination. The standard force characteristics measured by manufacturers and users of PFSs in characterisation and quality control studies include the break-loose force and glide force at constant velocity. Glide force is generally reported as a mean value at a given velocity, whereas design for a specified injection time must take account of the dynamic force profile of the combined drive system and load. Consider that the spring load is constantly decreasing as the spring expands, while the stopper friction varies with both velocity and lubrication. Siliconisation reduces stopper friction but lubricant mobility during stopper travel can add further variability.(7) Both 2-part and 3-part syringes can be used for various medical applications, but 3-part syringes are generally considered to provide better performance and ease of use due to their design. Final Thoughts

The smallest syringes available are those designed for specialized medical applications, such as insulin or tuberculin syringes. Finally, the hub is the plastic or metal base that connects the needle to the syringe barrel, ensuring a secure and stable connection during injection or withdrawal. What are the Types of Modern Syringes? Standard single-use syringes: These disposable syringes are designed for single use and are available in various sizes, ranging from 1 mL to 60 mL. The prefilled syringe (PFS) have widely published benefits over the traditional syringe and vial (1), leading to an increasing share of the drug delivery market in recent years.(2) The addition of an autoinjector to deliver a PFS can enhance safety and the patient experience(3), opening up new opportunities for home- and self-administration.(4) A critical task when integrating a PFS with an autoinjector is a detailed characterisation of the primary container, matching up measured characteristics of the syringe with their counterparts in the device. A useful framework for this is the concept of an interface specification, with requirements defined in terms of functionality and referenced to both the design input requirements of the device and a specification for the PFS.There are some multi-hinged needle covers available that can facilitate easier one-handed application: The story of in-use syringe breakages may have further twists in store. In the new world of biologics, with higher spring loads required to accommodate increased volumes and viscosities, we as an industry must remain vigilant and ensure the limits to syringe robustness are well understood. Force balance at the interface The needle hub is the plastic or metal base that connects the needle to the syringe barrel. It is designed to securely attach the needle to the syringe and provide a stable, leak-free connection during injection or withdrawal. Syringe disposal is a critical aspect of medical waste management, as it ensures the safety and health of healthcare professionals and the general public. Beyond purely functional considerations, challenges extend to the organisational interface between primary container and medical device teams. Pharmaceutical companies have long had dedicated teams focused on evaluation and selection of primary containers, including syringes, which play critical roles protecting the drug product, maintaining sterility and achieving the required shelf-life. More recently, dedicated medical device teams have appeared, focused on evaluation and selection of devices such as autoinjectors.
