Abstract
Abstract A syringe device for use with drawing blood or other fluids directly into a sealed sterile environment for culturing which includes a hollow housing defining the syringe chamber therein, further including a movable piston adapted for longitudinal sliding movement within the syringe chamber such that when the piston is withdrawn a partial vacuum is created within the chamber and blood is drawn therein, further including at least one culture cavity defined in the walls of the housing and opening into the chamber within the housing and being adapted to contain therein particularly chosen culturing media in accordance with the particular tests being conducted, further including a sealing means about the periphery of the movable piston such that after the fluid has been drawn into contact with the culturing cavities the piston may be moved back upwardly to seal the culturing media with respect to the outside environment and with respect to the chamber within the syringe to allow for a sterile culturing of the fluid, further including a hollow nipple means adapted to receive a needle detachably affixed thereto to facilitate drawing of fluids into the chamber of the syringe, also including a capping means which is detachably affixable to the nipple means to selectively seal hermetically the chamber from the external environment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A culturing syringe device for withdrawing the fluid to be cultured directly into a sterile sealed culturing environment comprising: a. a hollow housing defining a syringe chamber therein; b. at least one closed culturing cavity defined in the lateral walls of said housing to be selectively openable into said syringe chamber, each said closed cavity having culturing media therein; c. a movable piston located within the syringe chamber and adapted for longitudinal sliding movement therein, said piston including a head area and a peripheral area, said peripheral area providing a sealing means to selectively seal hermetically said closed culturing cavities from said syringe chamber and from the ambient environment; d. hollow nipple means in one end of said housing providing fluid flow communication between said housing and the external environment; and e. hollow needle means detachably affixed to said nipple means to allow fluid flow communication with the external environment.
Claim 2
Dependent Claim
150 words
A culturing syringe device for withdrawing the fluid to be cultured directly into a sterile sealed culturing environment comprising: a. a hollow housing defining a syringe chamber therein; b. at least one closed culturing cavity defined in the lateral walls of said housing to be selectively openable into said syringe chamber, each said closed cavity having culturing media therein; c. a movable piston located within the syringe chamber and adapted for longitudinal sliding movement therein, said piston including a head area and a peripheral area, said peripheral area providing a sealing means to selectively seal hermetically said closed culturing cavities from said syringe chamber and from the ambient environment; d. hollow nipple means in one end of said housing providing fluid flow communication between said housing and the external environment; and e. hollow needle means detachably affixed to said nipple means to allow fluid flow communication with the external environment.
Claim 3
Dependent Claim
30 words
The device as defined in claim 1 further comprising a capping means being detachably affixable to said nipple means to selectively seal hermetically said chamber from the external ambient environment.
Claim 4
Dependent Claim
26 words
The device as defined in claim 1 further including a mated securing means configured on the exterior of said nipple means and on said needle means.
Claim 5
Dependent Claim
14 words
The device as defined in claim 3 wherein said securing means comprises threaded sections.
Claim 6
Dependent Claim
12 words
The device as defined in claim 1 wherein said housing is tubular.
Claim 7
Dependent Claim
17 words
The device as defined in claim 1 wherein said housing is configured as a hollow cylindrical tube.
Claim 8
Dependent Claim
34 words
The device as defined in claim 1 including means for removing said piston from said chamber to allow direct access to said cavities for cleaning and the like including recharging with fresh culturing media.
Claim 9
Dependent Claim
190 words
A culturing syringe device for withdrawing fluid to be cultured directly into a sterile sealed culturing environment comprising: a. a hollow round tubular housing defining a cylindrical syringe chamber therin; b. at least one closed culturing cavity defined in the lateral walls of said housing to be selectively openable internally into said syringe chamber, each said culturing cavity having culturing media therein; c. a movable cylindrical piston located within said syringe chamber and adapted for longitudinal sliding movement therein, said piston including a head area and a peripheral area, said piston being removable to facilitate access to the interior of said housing, said peripheral area providing a sealing means to selectively seal hermetically said culturing cavities from said syringe chamber and from the ambient external environment; d. hollow nipple means in one end of said housing selectively providing fluid flow communication between said chamber and the external environment; e. hollow needle means adapted to be detachably affixed to said nipple means to allow fluid flow communication with the external environment; and f. capping means detachably affixable to said nipple means to selectively seal hermetically said chamber from the external environment.
