Abstract
Abstract This invention relates to augmented polymeric hypodermic needles and lancets. A flexible polymeric hypodermic needle or lancet is stiffened and made to more readily pierce the skin by working in conjunction with an augmenting structure. The devices are by their nature safer than present metal hypodermic needles or lancets. "Anti-stick", one-time use, and safety shielded models are demonstrated. Novel manufacturing methods will lead to devices that are less expensive than their metal counterparts. Unlike metal hypodermic devices these can be easily incinerated. This invention makes possible safe, easy to use, low cost, disposable hypodermic devices for injection, blood sampling and testing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
68 words
A hypodermic device for performing a piercing process comprising: a flexible polymeric piercing member and an augmenting means at least partly about said piercing member and includes a resilient foam at least partly about said piercing member and a guard at least partly about said foam wherein said augmenting means provides such stiffness to said piercing member in order for said piercing member to perform the piercing process.
Claim 2
Dependent Claim
68 words
A hypodermic device for performing a piercing process comprising: a flexible polymeric piercing member and an augmenting means at least partly about said piercing member and includes a resilient foam at least partly about said piercing member and a guard at least partly about said foam wherein said augmenting means provides such stiffness to said piercing member in order for said piercing member to perform the piercing process.
Claim 3
Dependent Claim
18 words
The hypodermic device for performing the piercing process of claim 1 wherein said piercing member is a lancet.
Claim 4
Dependent Claim
35 words
The hypodermic device for performing the piercing process of claim 1 wherein said augmenting means further comprises a slidable guard which is at least partly about said foam and in slidable relationship with said member.
Claim 5
Dependent Claim
13 words
The hypodermic device of claim 3 wherein said piercing member is a lancet.
Claim 6
Dependent Claim
92 words
A hypodermic device for performing a piercing process comprising: a flexible polymeric piercing member having a piercing tip and an augmenting means which is at least partly about and is in slidable relationship with said piercing member and includes a resilient foam at least partly about and slidably engaged with said piercing member and a guard at least partly about said foam and in slidable relationship with said piercing member wherein said augmenting means provides such stiffness to said piercing member in order for said piercing member to perform the piercing process.
Claim 7
Dependent Claim
92 words
A hypodermic device for performing a piercing process comprising: a flexible polymeric piercing member having a piercing tip and an augmenting means which is at least partly about and is in slidable relationship with said piercing member and includes a resilient foam at least partly about and slidably engaged with said piercing member and a guard at least partly about said foam and in slidable relationship with said piercing member wherein said augmenting means provides such stiffness to said piercing member in order for said piercing member to perform the piercing process.
Claim 8
Dependent Claim
13 words
The hypodermic device of claim 5 wherein said piercing member is a lancet.
Claim 9
Dependent Claim
72 words
A hypodermic device for performing a piercing process comprising: a flexible polymeric piercing member with a piercing tip; and an augmenting means at least partly about said piercing member and includes a resilient foam at least partly about said piercing member and a guard at least partly about said foam wherein said augmenting means provides such stiffness to said piercing member in order for said piercing member to perform the piercing process.
Claim 10
Dependent Claim
72 words
A hypodermic device for performing a piercing process comprising: a flexible polymeric piercing member with a piercing tip; and an augmenting means at least partly about said piercing member and includes a resilient foam at least partly about said piercing member and a guard at least partly about said foam wherein said augmenting means provides such stiffness to said piercing member in order for said piercing member to perform the piercing process.
Claim 11
Dependent Claim
13 words
The hypodermic device of claim 7 wherein said piercing member is a lancet.
Claim 12
Dependent Claim
17 words
The hypodermic device of claim 7 wherein said guard is in slidable relationship with said piercing member.
Claim 13
Dependent Claim
13 words
The hypodermic device of claim 9 wherein said piercing member is a lancet.
