Syringe design concept

This drum will have degrees of rotation which would allow it to mix the insulin before dosing. Consequently, line inspectors randomly check components at fixed time intervals to ensure they meet size, shape, and consistency specifications. American Society of Health-System Pharmacists, They perform inspections of each of these companies to ensure that Syringe design concept are following good manufacturing practices, handling complaints appropriately, and keeping adequate records related to design and production.

If you go to your temporary url http: Visual inspection is the primary test method. Syringe Loading Figure 3: As the lever arm rotates about a fixed axis, Syringe design concept other part of the lever arm swings into place, securing the syringe.

Parallel Orientation with Mixing Oscillation Another possibility is a device that would store two insulin bottles side by side. The product offers ease in handling, with a uniquely easy delivery system. Depending on the design, the needle can also be attached at this time, along with the safety cap.

Companion to Handbook of Injectable Drugs.

The exact design will depend to some extent on how the device will be used. The EasyPoint design places the release button perpendicular to the syringe barrel, so instead of pushing toward the needle tip, your finger pushes toward the syringe barrel, eliminating the forward pushing motion toward the patient.

Concept Classification Tree for Mixing Cloudy Insulin Before injecting long-acting insulin, the insulin in the bottle must be mixed to a uniform consistency.

One such improvement was the incorporation of a glass piston within the cylinder. Undersized Form Similar to the molded form described under Form Fit, a piece of material would be molded or milled such that it loosely conforms to the shape of the syringe.

Self-Closing Latch The syringe would be loaded in a manner similar to that of the clips, however the securing mechanism would be different. As the wheel was driven by a motor, the bottles would spin in place, properly mixing the insulin. Assembly and packaging 4 When all of the component pieces are available, final assembly can occur.

As it moves along the production line, the steel is further formed and rolled into a continuous, hollow wire. Various important developments needed to occur before injections through a hypodermic syringe could be conceived. Best of all, leveraging years of focused research and experience with safety needle products, RTI has achieved significant cost savings through creative design optimization and an integrated highly efficient manufacturing process, all of which means lower cost to the customers.

A New Approach to the Design of Retractable Needle Technology

On platforms that enforce case-sensitivity example and Example are not the same locations. Additionally, they must be sterilizable and nontoxic. Early nineteenth century physicians were not aware that drugs could be introduced into the body through the skin. It is made up of a hollow needle, which is attached to a tube and a plunger.

As the syringe is inserted, the barrel makes contact with a lever arm in the center of the mechanism. The plastic or glass is supplied as granules or powder and is fed into a large hopper.

The Manufacturing Process There are many manufacturers of hypodermic needles, and while each one uses a slightly different process for production, the basic steps remain the same, including needle formation, plastic component molding, piece assembly, packaging, labeling, and shipping.

In this process the plastic is heated, converting it into a liquid. Graduation markings may also be printed on the main tube body at this point in the manufacturing process. Correct placement is ensured by the form of the bottle being molded into the back of the cylinder into which the door is closing.

Some manufacturers make short, wide tubes, and others make long, thin ones. Then to release the pivot, a release button could be pressed which would cause the pivot to return to its normal position, popping the bottle out so it can be removed easily.For the design of the mechanism to hold and secure the syringe during the process of needle insertion and syringe dosing, several concepts were generated.

The following is a presentation of the feasible approaches to securing the syringe. The effect of a new syringe design on the ability of rheumatoid arthritis patients to inject a biological medication. One syringe, referred to as the RAPID 2 syringe (R in Fig. 1), is a standard pre-filled “off-the-shelf” syringe, comprised of a flat thumb pad.

Concept Generation

SKETCH 06 (left): This sketch marked a turning point in the design as it established the syringe's body style. CONCEPT 01 (left): Board detailing attributes of an alternate concept for the syringe.

SIZE & CHARACTERISTICS (right): Board detailing attributes of final concept for the syringe. Only the syringe holder needs support; other pieces printable without support structures.

Design There are many hypodermic syringe designs available. However, all of them have the same general features, including a barrel, plunger, needle, and cap.

The barrel is the part of the hypodermic needle that contains the material that is injected or withdrawn. A .
