Abstract
Abstract The device comprises a base plate and a cover plate held in spaced, parallel relation by a pair of spaced, parallel side walls. A rectangular rib, which extends between the sidewalls approximately midway between the base and cover plates, has therein a central, circular opening which registers coaxially with like openings in the base and cover plates. A cocking bar, which is reciprocable between the side walls beneath the rib, has a central opening movable into and out of registry with the opening in the rib. In use, the cocking bar is shifted to offset its opening slightly from the opening in the rib; and a syringe is inserted, needle-down, through the openings in the cover plate, rib and cocking bar, but with the lower end of the syringe barrel or housing seated on a marginal portion of the cocking bar around its now-offset opening. A resilient member is placed over a shoulder on the upper end of the syringe housing, so that when the opening in the base plate is positioned over the spot into which the needle is to be inserted, the operator needs only to shift the cocking bar slightly to register its opening with that in the rib. The lower end of the syringe thus slides off the retaining portion of the cocking bar and is urged suddenly down to project its needle through the opening in the base plate and into the operator's body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
252 words
A device for inserting the needle of a syringe into a body, comprising a first pair of spaced members having therein a pair of registering openings, two additional members mounted adjacent each other in the space between said first pair of members, one of said additional members having therein an opening registering with the pair of openings in said first pair of members, means mounting the other of said additional members for movement selectively between a cocked position in which an opening herein is laterally offset slightly from the opening in said one additional member, and a fired position in which the opening therein registers with the opening in said one additional member, and resilient means mounted on one of said first pair of members and operable, when the other of said additional members is in its cocked position, releasably to support a syringe needledown in the opening in said one of said first pair of members with the lower end of said syringe urged resiliently against a marginal portion of said other additional member adjacent said opening therein, said marginal portion of said other additional member being movable from beneath said lower end of the syringe upon movement of said other additional member to its fired position, whereupon the syringe is urged suddenly downwardly through the now-registering openings in said members to inject the needle on the lower end thereof through the opening in the other of said first pair of members and into any portion of a body registering therewith.
Claim 2
Independent Claim
252 words
A device for inserting the needle of a syringe into a body, comprising a first pair of spaced members having therein a pair of registering openings, two additional members mounted adjacent each other in the space between said first pair of members, one of said additional members having therein an opening registering with the pair of openings in said first pair of members, means mounting the other of said additional members for movement selectively between a cocked position in which an opening herein is laterally offset slightly from the opening in said one additional member, and a fired position in which the opening therein registers with the opening in said one additional member, and resilient means mounted on one of said first pair of members and operable, when the other of said additional members is in its cocked position, releasably to support a syringe needledown in the opening in said one of said first pair of members with the lower end of said syringe urged resiliently against a marginal portion of said other additional member adjacent said opening therein, said marginal portion of said other additional member being movable from beneath said lower end of the syringe upon movement of said other additional member to its fired position, whereupon the syringe is urged suddenly downwardly through the now-registering openings in said members to inject the needle on the lower end thereof through the opening in the other of said first pair of members and into any portion of a body registering therewith.
Claim 3
Dependent Claim
62 words
A device as defined in claim 1, wherein said resilient means comprises a resilient strap secured at opposite ends to said one of said first pair of members adjacent diametrally opposite sides of the opening therein, said strap being insertable intermediate its end over a shoulder on said syringe releasably to support the syringe in its needle-down position in the last-named opening.
Claim 4
Dependent Claim
35 words
A device as defined in claim 2, wherein said strap comprises a rubber band having diametrally opposite sides thereof releasably engaged in notches formed in opposite ends of said one member of said first pair.
Claim 5
Dependent Claim
109 words
A device as defined in claim 1, wherein a shoulder on the syringe is engageable with said one of said first pair of members around marginal portions of its opening, when the other of said additional members is moved to its fired position, thereby to limit the downward movement of the syringe in said openings, and the outside surfaces of said first pair of members are spaced from each other a distance slightly greater than the distance between the shoulder and needle of the syringe so that the needle will project a predetermined distance beyond said other of said first pair of members, when moved to its fired position.
Claim 6
Dependent Claim
64 words
A device as defined in claim 4, including a pair of spaced, parallel sidewalls interposed between said first pair of members to support the latter in spaced relation, said two additional members extending transversely between said side walls, and being spaced from the other of said first pair of members, whereby the lower end of said syringe remains visible when in its fired position.
Claim 7
Independent Claim
236 words
A device for inserting the needle of a syringe into a body, comprising a base having a plane, lower surface disposed to be positioned against the surface of a body into which a syringe needle is to be inserted, and having therein a central opening, means mounted on the upper surface of said base for releasably supporting a syringe in a cocked position on said base, and with the needle thereof disposed in spaced, coaxial relation with said opening, said means including a movable latching member releasably engageable with said syringe adjacent its lower end releasably to prevent movement of the syringe toward said opening and resilient means releasably engageable with said syringe adjacent its upper end resiliently to urge said syringe against said latching member, when the latter is in a first position, and to urge said syringe downwardly to a second position in which the needle thereon projects through said opening and a predetermined distance beyond the lower surface of said base, when said latching member is moved to a second position, said base being made of transparent material, and said means for supporting said syringe further comprising a pair of spaced side members supporting said latching member above said base and forming between said base and said latching member an open space which permits the lower end of said syringe to be viewed when the syringe has been moved to its lowered position.
