（专利）与传统的注射笔相比，氮驱动对药物没有任何化学作用，无污染，无毒性，无副作用，操作简单，可以用于各种制剂的无针无痛注射，尤其是粉针剂和安瓿制剂，一般的注射笔难以胜任。 PenJet is a small, inexpensive, needle-less, disposable jet injector that delivers a single dose of medication. It is powered by self-contained compressed inert gas and is either shipped prefilled with a drug or filled prior to delivering a needle-less injection.
Ease of operation and low cost make PenJets applicable for usages ranging from mass inoculations of entire populations to home delivery of pharmaceuticals by patients or their care-givers. PenJets are available for needle-less subcutaneous, intradermal and some intramuscular injections. Dosage size can be as large as 0.5 ml or as small as 0.1 ml.
PenJet one handed operation feels and functions like an ordinary syringe. Its patented fingersets are ergonomically designed for ideal hand positioning for either assisted or self administration of needle-less injections. To give a needle-less injection, pressure is exerted on the rear of the PenJet, in the precise place the plunger is pushed on an ordinary syringe. Because of these similarities, users intuitively know how to use the PenJet and have complete control over the administration of a needle-less injection.
PenJet Patented Gas Power Supply 微型压缩氮气制动系统
PenJet’s self contained inert gas canisters are powered by nitrogen. Unlike carbon dioxide, nitrogen has a wide functional temperature range and can be kept refrigerated right up to injecting. PenJet uses patented metal gas canisters with an in line valve to eliminate leakage causing underpowered injection commonly associated with plastic gas canisters. PenJets can be stored for long periods of time and, unlike spring powered devices, repeatedly deliver identical injections.
粉针无针无痛注射器 PenJet Lyophilized Delivery Systems
In addition to conventional liquid medications and vaccines, PenJets can store, mix and administer needle-less injections of freeze-dried (lyophilized) drugs. This is particularly relevant to the increasing number of highly potent, biotechnologically derived proteins that require lyophilization to maintain shelf life.
PenJet Filling Systems 药品灌装系统
Filling equipment is provided by PenJet Corporation for small test runs and for full production. Its patented continuous feed, high-speed aseptic PenJet automated filling system is anticipated to debut in 2003. PenJet is a small, inexpensive, needle-less, disposable jet injector that delivers a single dose of medication. It is powered by self-contained compressed inert gas and is either shipped prefilled with a drug or filled prior to delivering a needle-less injection. |
安瓿无针注射装置 PenJet Ampoules
PenJet polycarbonate ampoules are an integral part of the device housing. They are filled in an aseptic environment fully assembled, ready for the inert gas canister which holds the delivery charge. The standard size PenJet ampoule holds 0.5 ml. It is manufactured in gamma-sterilized polycarbonate.
PenJet has patented technology that enables needle-free injections of multi-component drugs. These drugs can include both a pharmaceutical reagent and a diluent, which may be combined immediately prior to injection.
Multi-component drugs are frequently stored in separate vessels because they are not stable for long periods of time after being mixed. This makes it difficult to store them in either conventional, pre-filled syringes or needle-free injectors. PenJet’s patented filling and mixing technology provides a safe and cost-effective solution to this problem, and is applicable to a host of pharmaceutical products.
PenJet enables pharmaceutical manufacturers to package their innovative lyophilized drugs in a needle-free, single use, inexpensive jet injector. it is particularly relevant to the increasing number of highly potent, biotechnologically derived proteins that require lyophilization to maintain their required shelf life.
The patented devices include a variety of shuttle configurations that allow a reagent and a diluent to be contained in separate chambers and mixed immediately prior to injection. To give a needle-free injection with a PenJet once the reagent and diluent are combined, a safety ring that avoids accidental triggering is removed, the nozzle is placed against a suitable injection site, such as the upper arm, thigh or stomach, and the PenJet administers the injection when gently pressed. After use, the PenJet can be safely discarded in any trash receptacle, or recycled into non-medical devices, since it has no needle and has injected all the medication or vaccine it contained.
PenJets are tailored for each specific drug it delivers. Exclusive licenses for particular drugs are available. An exclusive license offers pharmaceutical firms a sustainable competitive advantage in a patented, low cost, needle-less drug delivery system.
In addition to its needle-less disposable jet injectors, Penjet Corporation provides its exclusive, continuous feed, high-speed, aseptic automated filling Systems.
