     BACKGROUND OF THE INVENTION 
     Technical Field of the Invention 
     The disclosure generally relates to syringes and a method of using the same, and more specifically to a multi-cycle syringe that will auto-disable. 
     Description of Related Art 
     The World Health Organization estimates, in fact sheet number 234, that twelve billion (12 billion) annual injections occur in developing and transitional nations. Many of these injections occur through the shared use of contaminated needles and syringe assemblies. Bloodborne diseases such as hepatitis B, hepatitis C and HIV/AIDS are transmitted through injections due to unsafe injection practices, such as the use of re-used contaminated needles and syringe assemblies. In many developing and transitional countries, the proportion of the population infected with hepatitis B and hepatitis C exceeds 10 times the prevalence seen in developed countries, and in many of these countries, unsafe injections account for a large proportion of new cases of infection. Thus, the cost of unsafe injection practices in developing countries is high. 
     One previous approach was to use a pre-filled single direction, single use syringe. A problem with this approach was that the syringe must be filled with a specific compound before being given to the medical professional. 
     Another approach was to use a syringe wherein the operator is required to physically break or disable the syringe assembly; however, an operator may not follow through with the disabling task. 
     Another approach was to use a syringe assembly with mechanics to destroy the syringe assembly, such as a stem that pierces a hole in syringe body; however such design may be circumvented as well. 
     Moreover, the above syringes designs limit the number of cycles or strokes of the syringe assembly to one (1) cycle or stroke before disabling and prohibit their use with medicines and vaccines distributed in a dehydrated and/or freeze dried form, whereby such dehydrated and/or freeze dried medicines and vaccines require a multi cycle syringe to load a wetting agent to activate the medicines and vaccines. It is important to note that such dehydrated and/or freeze dried medicines and vaccines are especially utilized in remote and difficult to reach developing and transitional nations due to their extended shelf life. 
     Therefore, it is readily apparent that there is a recognizable unmet need for a multi-cycle auto-disable device that is simple to setup, allows for multi-cycle operation, such as applying a wetting agent to dehydrated and/or freeze dried medications and vaccines, thereafter auto-disable, and provides an economically feasible syringe assembly, especially for developing and transitional nations to promote safe and sterile medical care. 
     SUMMARY 
     Briefly described, in a preferred embodiment, the present apparatus and method overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing a multi-cycle auto-disable device that is simple to setup, allows for multi-cycle operation, such as applying a wetting agent to dehydrated and/or freeze dried medications and vaccines, thereafter auto-disables, and provides an economically feasible syringe assembly, especially for developing and transitional nations to promote safe and sterile medical care. 
     The present apparatus and method includes a multi-cycle auto-disable syringe having a stem, container, and a plunger. The plunger includes at least one passageway or tube with a soluble substance therein that maintains a seal on compounds within the container&#39;s chamber, thus allowing a multi-cycle usage to dispense medication to patients, but further use with other patients is prevented after the soluble substance dissolves; thus, disabling the syringe. 
     According to its major aspects and broadly stated, the present disclosure describes a syringe device, wherein the syringe device has a stem, a plunger, and a container. The plunger has a passageway or tube filled with a soluble substance, and the container has a chamber sealed by the plunger, and the soluble substance prevents fluid and/or air communication between the chamber and the axial chamber. 
     The plunger also has a cover, such as a parabolic cover, and at least one tube positioned therethrough the plunger, the tube allows fluid and/or air communication between the chamber and the axial chambers when the cover is open and prevents fluid and/or air communication between the chamber and the axial chambers when the cover is closed. The plunger may also have a protrusion formed thereon, and the cover is integral to the protrusion and is further secured in a closed position to the perimeter of the plunger by the soluble substance. 
     Moreover, the stem may also have a secondary channel, and the secondary channel provides fluid communication between the chamber-plunger tube and the axial chambers. The plunger may also include a cavity, and the tube has a tube bottom, and the tube bottom is disposed at or near the cavity. 
     Alternatively, the plunger may also have a cover, such as a parabolic cover or other configured cover, and at least one tube positioned therethrough the plunger, the tube allows fluid and/or air communication between the chamber and the axial chambers when the cover is open and prevents fluid and/or air communication between the chamber and the axial chambers when the cover is closed wherein the cover may be form fitted or memory fitted thereto the plunger and the closed cover may require contact with a surface or object to open the cover or change its state and thus, disable the syringe. 
     The cover, such as a parabolic cover, is configured to stay in the open position but is forced into a closed or sealed position and may be held in place by the soluble substance acting as an adhesive. Once the bond of the adhesive has failed, the structure of the parabolic seal forces it to return to its original open position, enabling passageway between the chamber and the axial chambers. 
     Hydraulics/Hydrodynamics 
     The function of the syringe assembly is based on hydraulic and/or hydrodynamic principles based on the seal created between the plunger and body/container. The stem transfers external forces to the plunger. The linear motion of the stem and plunger, as a result of the external force, creates positive and negative hydraulic pressure in the forward cavity defined by the plunger and body/container. A forward motion of the stem and plunger creates a positive pressure in the forward cavity and is the positive pressure that forces the injection material (fluid and/or air) contained in the forward cavity to exit the forward cavity and travel through the small orifice of the needle. Conversely, a rearward motion or retraction of the stem and plunger pulls the plunger backwards creating a negative pressure in the forward cavity and is the negative pressure that pulls the injection material (fluid and/or air) into the forward cavity through the small orifice of the needle to fill the forward cavity. During the linear motion of the stem and plunger assembly the plunger maintains a seal between the plunger and the sidewall of the container/body. This seal is critical to the creation and control of the hydraulic pressure differentials created in the forward cavity to move injection material (fluid and/or air) in and out of the forward cavity. 
     Multi-Cycle Sequence 
     In use, for example, the syringe is injected into a vial holding suspension media. Next, the stem is pushed inward to create positive pressure inside the vial of suspension media, and then the stem is pulled outward to draw the suspension media into the syringe, and the soluble substance begins dissolving. Next, the stem is pushed inward to inject the suspension media into a vial of dried medication or vaccine, and then the stem is pulled outward to draw the medication now in suspension into the syringe. Subsequently, the stem is pushed inward to inject the medication into a patient. Next, the soluble substance dissolves, after which the chamber or forward cavity and the axial chambers are in fluid communication; thus, disabling plunger from creating positive or negative hydraulic pressure in the forward cavity defined by the plunger and body/container. 
     Injection material, such as a fluid, entry into forward cavity defined by the plunger and body/container, more specifically when the injection material comes in contact with the soluble substance; this starts the clock for auto-disable function of the syringe. Once the soluble substance is dissolved the syringe is disabled. The soluble characteristics of the soluble substance, whether adhesive bond, mechanical bond, or mechanical block, determines the rate and/or time of deterioration and failure of the forward cavity seal defined by the plunger and body/container rendering the syringe unusable. The time the syringe is functional and the number of cycles of use the syringe may accomplish is determined by the rate of deterioration. Controlling the deterioration of the soluble substance blocking the secondary passageway that circumvents the seal defined by the plunger and body/container enables a designer to set the time of use or number of cycles of use for the syringe. The disable time is defined as the time required for the soluble substance to dissolve unblocking the secondary passageway that circumvents the seal defined by the plunger and body/container, or the time required to deteriorate soluble substance holding the cover in its closed position. Using soluble substance allows for exposure of the injection material (fluid medium) being dispensed or injected by the syringe to be the controlling agent or event to start the deterioration of the soluble substance. Therefore, by varying the composition of the soluble substance this controls the rate of deterioration and thus the cycle count and usage time of the syringe allowing cycling of the syringe more than one time, such as when using a dried vaccine or material that requires the introduction of a re-hydrating agent. 
     In another embodiment, the syringe has a stem, a plunger, and a container. The stem has a depresser, the plunger has a soluble substance, and the container has a chamber. The soluble substance prevents fluid communication between the chamber and the depresser. The plunger also has a tube and a cavity, and the tube has a tube bottom, the tube bottom being at or near the cavity. The stem also has a secondary channel. The stem also has a base, the base having a base top. The base is preferably located within or near cavity. The base top is disposed proximate the tube bottoms when the stem is being pushed inward. 
     The soluble substance is any substance or compound as known in the art that will dissolve under the circumstances described herein, including, for exemplary purposes and without limitation, a natural or organic based adhesive such as potato starch, a sugar and water mixture, a mechanical binder such as that used to bind aspirin in pill form, or the like. Moreover, the soluble substance may dissolve over a period of time after coming into contact with compound, medication, and its mixture, such as suspension media, and/or wetting agent or medication, such that preferably the substance dissolves within a predetermined time, such as minutes. 
     In an alternate embodiment, the plunger also has a cover, and the tube further has a tube top. The cover is initially secured to the stem by the soluble substance, and the secured cover prevents fluid communication between the tube and the chamber. The stem has an axial chamber and a secondary channel. 
     More specifically, the present disclosure of a preferred embodiment is a syringe, the syringe having a stem and a container. The stem has a plunger, axial supports, axial chambers, secondary channels, a depresser, and a base, the depresser having a depresser diameter, and the base having a base diameter and a base top, and the axial supports having axial chambers. The container has a lip, a chamber, a bottom, a sidewall, a container diameter, and an extruder, the extruder having a channel. The plunger has a plunger diameter, a cover, a bottom interior periphery, a bottom inner diameter, a bottom outer diameter, a bottom exterior periphery, a tube, and a protrusion, the tube having a tube bottom, a tube top, and a soluble substance, and the protrusion has a plunger top and a protrusion diameter, and the cover has a cover periphery. The chamber preferably includes a compound, which includes medication, suspension medication, and dried medication, and may include air before use has been initiated. 
     The plunger is preferably fixedly secured to the base of the stem. The axial chambers are disposed between the axial supports, the axial supports being disposed between the base and the depresser. The extruder extends from the container, and the compound is ejected from the container via the extruder channel, which preferably has a tubular needle attached through which the compound preferably flows into a patient or into a vial. 
     The cover is disposed above and attached to the protrusion, and when the cover is open then the cover does not prevent fluid connectivity between the tubes and the chamber, and the stem is disposed within the plunger. 
     When the cover is closed, it smothers or covers the tubes, therein preventing any fluid and/or air from transiting from the cavity through the tubes. The tubes are may also be filled with the soluble substance. 
     The plunger is disposed upon the stem within the container. The base is disposed within the cavity. When the stem is pushed into the container, the base top of the stem is disposed against the tube bottom of the tubes, thus preferably preventing fluid communication between the cavity and the chamber and enabling positive pressure in the cavity. When the stem is pulled from the container, the base is disposed against the bottom interior periphery enabling fluid communication between the cavity and the chamber and disabling negative pressure in the cavity. 
     In one embodiment, the protrusion on the plunger is substantially flat. The bottom exterior periphery of the plunger extends around the bottom interior periphery, and the bottom inner diameter is the greatest distance between any two points on the bottom interior periphery. The tubes are preferably, although not necessarily, filled with a soluble substance, thereby preventing liquid communication between the chamber and cavity. When the cover is closed, the cover is also preventing liquid communication between the chamber and cavity. 
     In use, the syringe is injected into a vial holding suspension media. Next, the stem is pushed inward to create positive pressure inside the vial of suspension media. Subsequently, the stem is pulled outward creating a negative pressure in the syringe to draw suspension media into the syringe. Concurrently, the soluble substance begins decomposing. The stem is pushed inward creating a positive pressure inside the syringe to inject suspension media in the vial of dried medication. Subsequently, the stem is pulled outward creating a negative pressure in the syringe to draw medication into the syringe. The stem is then pushed inward to create positive pressure inside the syringe to inject medication into the patient. Finally, at some point the substance dissolves, thus the cavity and chamber are in fluid communication preventing hydraulic pressure in the syringe chamber. 
     When the soluble substance at the cover periphery fully dissolves, the cover opens preventing hydraulic pressure in the syringe chamber. This is because the cover is naturally disposed towards the depiction shown when the cover is open, but the soluble substance holds the cover down enabling hydraulic pressure in the syringe chamber. Subsequently, the soluble substance in the tubes dissolves, thus the cavity and chamber are in fluid communication. However, even when the cover and the tubes are open, fluid communication between chamber and cavity may be temporarily interrupted when the stem is moved inward, thus disposing the base top in contact with tube bottom, which temporarily seals the tubes. Thus, allowing for positive pressure in the cavity in the inward direction only and allowing medication resident in the chamber to be discharged from the syringe. 
     Syringe may not include a cover, in which case the soluble substance in the tubes is the only object preventing fluid communication between the cavity and chamber. Alternatively, the syringe may have a cover, and the tubes may not be filled with a soluble substance, in which case the cover is the only object preventing fluid communication between the cavity and chamber. 
     Preferably, the medication is dispensed from the chamber before the chamber and cavity are in fluid communication. However, as long as the chamber and cavity are not in fluid communication, the action of pushing the stem inward will force the plunger top against the tube bottoms, thus temporarily preventing fluid communication while medication is injected into the patient. 
     When the chamber and cavity are in fluid communication, the chamber and axial chambers are also in fluid communication. Accordingly, when the stem is pulled outward, the chamber can be filled from air that was within the axial chambers, thus preventing and/or interfering with compound attempting to be pulled into the chamber via the tubular needle. In this situation, the syringe has been disabled and therefore syringe is incapable of further use, and thus, incapable of assisting the further spread of communicable diseases and viruses, excepting that the syringe can still dispense the compound within it, as described elsewhere. 
     It will be recognized that the axial chambers may be any configuration that allows for fluid communication between secondary channels and atmospheric air that generally surrounds the outside of the syringe, such as, for exemplary purposes only, the atmospheric air disposed near the depresser. Similarly, it will be recognized that secondary channels may be in any configuration that allows for fluid communication between the chamber and axial chambers. Further, it will be recognized that the tubes may be any configuration that allows for fluid communication between the chamber and axial chamber. 
     Accordingly, a feature of the multi-cycle auto-disable device is its ability to allow any type of compound to be dispensed. 
     Another feature of the multi-cycle auto-disable device is its ability to be relatively easy to manufacture and is not cost prohibitive utilizing a high percentage of existing tooling and manufacturing processes. 
     Yet another feature and advantage of the multi-cycle auto-disable device is its ability to be transparent in application to the end user requiring no action other than normal use to be activated. 
     Yet another feature and advantage of the multi-cycle auto-disable device is its ability to not require any action by the user to initiate function. 
     Yet another feature and advantage of the multi-cycle auto-disable device is its ability to not be circumvented by the user. 
     Yet another feature and advantage of the multi-cycle auto-disable device is its ability to not require being pre-filled. 
     Still another feature of the multi-cycle auto-disable device is its ability to be easy to use requiring minimal education and/or training of the user. 
     Yet another feature of the multi-cycle auto-disable device is its ability to continue to be used for one complete multi-cycle use and then auto-disable to prevent further uses. 
     Yet another feature of the multi-cycle auto-disable device is its ability to help prevent the spread of infectious diseases. 
     These and other features of the multi-cycle auto-disable device will become more apparent to one skilled in the art from the prior Summary, and following Brief Description of the Drawings, Detailed Description, and Claims when read in light of the accompanying Detailed Drawings.

     Turning now to  FIG. 5 , pictured therein is an expanded view of plunger  300  disposed upon stem  200  within container  400 , wherein cover  320  is closed. In the exemplary embodiment shown, base  240  is disposed within cavity  380 . When stem  200  is pushed into container  400 , plunger  300  travels in I into container  400  (shown in  FIG. 1 ) enabling compression, discharge of compound C from extruder channel  435  of extruder  430 . Further, on the shown embodiment, plunger diameter  305  is proximately equal to container diameter  450 , thus preventing compound C from exiting chamber except through either extruder channel  435  or tubes  330 . 
     It is contemplated herein that base diameter  245  is preferably less than bottom out diameter  357  (best shown in  FIG. 4A ), thus enabling a passageway therethrough plunger  300  such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400  via tubes  330  and passage way shown by air A. 
     It is contemplated herein an alternate embodiment that when plunger  300  travels in I into container  400  base top  247  of base  240  is disposed against tube bottom  332  of tubes  330 , thus preferably preventing fluid communication between cavity  380  and chamber  460  or disabling a passageway therethrough plunger  300  such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400  via tubes  330  and passage way shown by air A. Such configuration enables a single discharge syringe  100  because of positive pressure being created in chamber  460  by motion inward I of plunger  300 . 
     Turning now to  FIG. 6 , pictured therein is an expanded view of plunger  300  disposed upon stem  200  within container  400 , wherein cover  320  is open. When cover  320  is open, cover  320  no longer smothers or covers tube top  334  of tubes  330 , wherein air A within cavity  380  is fluidly connected to chamber  460 . When stem  200  is pulled from container  400  plunger  300  travels out O of container  400  (shown in  FIG. 1 ) disabling the drawing in or suction of compound C into extruder channel  435  of extruder  430  and/or the disabling of compression, discharge of compound C from extruder channel  435  of extruder  430 . Syringe  100  is disabled because fluid communication between cavity  380  and chamber  460  prevents the creation of negative pressure in chamber  460 . 
     It is contemplated herein that base diameter  245  is preferably less than bottom out diameter  357  (best shown in  FIG. 4A ), thus enabling a passageway therethrough plunger  300  such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400  via tubes  330  and passage way shown by air A. 
     It is contemplated herein that an alternate embodiment plunger  300  may travel out O from container  400  base top  247  of base  240  is removed from tube bottom  332  of tubes  330 , thus preferably enabling fluid communication between cavity  380  and chamber  460  and/or enabling a passageway therethrough plunger  300  such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in FIGS.  1 ) of container  400  via tubes  330  and passage way shown by air A. 
     It is further contemplated herein that if tubes  330  are filled with a substance  335  (shown in  FIG. 8B ) capable of dissolving or timed dissolving when in contact with compound C that once substance  335  has dissolved tubes  330  and passage way shown by air A define a passageway therethrough plunger  300 , such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400  disabling compression, discharge or to draw in, suction of compound C by syringe  100 , when stem  200  and plunger  300  travel out O or in I, respectively, of container  400  (shown in  FIG. 1 ). 
     Turning now to  FIGS. 7A-8B , illustrated therein is an alternate embodiment of plunger  300 , wherein protrusion  340  is substantially flat (best shown in  FIG. 8B ), and wherein cover  320  is closed. Turning more particularly to  FIG. 7A , bottom exterior periphery  360  of plunger  300  extends around bottom interior periphery  350 , wherein bottom inner diameter  355  is the greatest distance between any two points on bottom interior periphery  350 . Tubes  330  are preferably, although not necessarily, filled with substance  335 , thereby preventing liquid communication between chamber  460  and cavity  380 . When cover  320  is closed, cover  320  is also preventing liquid communication between chamber  460  and cavity  380 . 
     It is contemplated herein that when cover  320  is preferably releasably affixed to cover periphery  322  of plunger  300  by substance  335 , is closed, cover  320  smothers or covers tubes  330  blocking passage therethrough tubes  330 , thus enabling compression, discharge or to draw in, suction of compound C by syringe  100 , when stem  200  and plunger  300  travel out O or in I, respectively, of container  400  (shown in  FIG. 1 ). 
     Turning more particularly to  FIG. 8A-8B , tubes  330  preferably configured to define a blocked passageway therethrough plunger  300 , such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400 . It is contemplated herein that cover  320  is preferably releasably affixed to cover periphery  322  of plunger  300  by substance  335  and tubes  330  are preferably filled with substance  335 , thus enabling compression, discharge or to draw in, suction of compound C by syringe  100 , when stem  200  and plunger  300  travel out O or in I, respectively, of container  400  (shown in  FIG. 1 ). 
     Turning now to  FIGS. 9A-9B , illustrated therein is a different embodiment of plunger  300 , wherein protrusion  340  is substantially flat (best shown in  FIG. 9B ), and wherein cover  320  is open. Tubes  330  are preferably, although not necessarily, filled with substance  335 , thereby preventing liquid communication between chamber  460  and cavity  380 . When cover  320  is open, cover  320  is not preventing liquid communication between chamber  460  and cavity  380 . 
     Once substance  335  has dissolved cover  320  is released and returns to open, as shown in  FIGS. 3 and 6 , and once substance  335  has dissolved from tubes  330  to define a passageway therethrough plunger  300 , such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400 , thus disabling compression, discharge or to draw in, suction of compound C by syringe  100 , when stem  200  and plunger  300  travel out O or in I, respectively, of container  400  (shown in  FIG. 1 ). 
     When in use, stem  200  transfers external forces to plunger  300 . The linear motion inward I and outward O of stem  200  and plunger  300 , create positive and negative hydraulic pressure in chamber  460 . Motion inward I of plunger  300  creates a positive pressure in chamber  460 , thus forcing the extrusion of compound C or air A through extruder channel  435 , and subsequently the small orifice of a needle (not shown). Motion outward O of plunger  300  creates a negative pressure in chamber  460 , thus forcing the intake of compound C or air A through extruder channel  435 . During both motion inward I and outward O, plunger periphery  322  maintains a seal with the interior of sidewall  440  of container  400 . This seal allows for the positive and negative pressure to force the ejection or intake of compound C or air A. 
     Turning now to  FIG. 10 , method of using syringe  1000  comprises injecting syringe  100  into a vial holding suspension media SM via step  1010 . Via step  1020 , stem  200  is pushed in or inward I to create positive pressure inside the vial of suspension media SM. Subsequently, via step  1030 , stem  200  is pulled out or outward O, creating negative pressure in chamber  460 , to draw suspension media SM into syringe  100 . Concurrently, substance  335  begins decomposing. Via step  1040 , stem  200  is pushed in or inward I, creating positive pressure in chamber  460 , to inject suspension media SM in the vial of dried medication DM, which may comprise a vaccine. Subsequently, stem  200  is pulled out or outward O, creating negative pressure in chamber  460 , to draw medication M into syringe  100 , via step  1050 . Stem  200  is then pushed in or inward I, creating positive pressure in chamber  460 , to inject medication M into the patient, via step  1060 . Finally, via step  1070 , substance  335  dissolves, thus cavity  380  and chamber  460  become fluidly connected; thus, disabling plunger  300  from creating positive or negative hydraulic pressure in chamber  460  defined by plunger  300  and container  400 . 
     The soluble characteristics of substance  335 , whether adhesive bond, mechanical bond, or mechanical block, define the rate and/or time of deterioration and failure of seal of chamber  460 . The time syringe  100  is functional and the number of cycles syringe  100  may accomplish is determined by the rate of deterioration. Controlling the deterioration time allows the designer and/or manufacturer of syringe  100  to set the time of use or the number of cycles. 
     When substance  335  fully dissolves, via step  1070 , substance  335  at cover periphery  322  releases cover  320 , thus, cover  320  opens (best shown in  FIG. 6 ). Subsequently, substance  335  in tubes  330  dissolves, thus fluidly connecting cavity  380  and chamber  460 . However, even when cover  320  and tubes  330  are open, fluid communication between chamber  460  and cavity  380  may be temporarily interrupted when stem  200  is moved in or inward I, thus disposing base top  247  in contact with tub bottom  332  (best shown in  FIG. 6 ). 
     Moreover, once substance  335  has dissolved cover  320  is released and returns to open, as shown in  FIGS. 3 and 6 , and/or once substance  335  has dissolved from tubes  330  to define a passageway therethrough plunger  300 , such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400 , thus disabling compression, discharge or to draw in, suction of compound C by syringe  100 , when stem  200  and plunger  300  travel out O or in I, respectively, of container  400  (shown in  FIG. 1 ). 
     It will be recognized that in an alternate embodiment, syringe  100  does not comprise cover  320 , in which case substance  335  in tubes  330  is the only object preventing fluid communication between cavity  380  and chamber  460 . 
     Once substance  335  has dissolved from tubes  330  to define a passageway therethrough plunger  300 , such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400 , thus disabling compression, discharge or to draw in, suction of compound C by syringe  100 , when stem  200  and plunger  300  travel out O or in I, respectively, of container  400  (shown in  FIG. 1 ). 
     Alternatively, syringe  100  may comprise cover  320 , but tubes  330  may not comprise substance  335 , in which case cover  320  is the only object constantly preventing fluid communication between cavity  380  and chamber  460 . 
     Once substance  335  has dissolved cover  320  is released and returns to open, as shown in  FIGS. 3 and 6 , tubes  330  define a passageway therethrough plunger  300 , such as between chamber  460  (shown in  FIGS. 1, 3A and 6 ) and axial chamber  220  (shown in  FIG. 1 ) of container  400 , thus disabling compression, discharge or to draw in, suction of compound C by syringe  100 , when stem  200  and plunger  300  travel out O or in I, respectively, of container  400  (shown in  FIG. 1 ). 
     Preferably, medication M is dispensed from chamber  460  before chamber  460  and cavity  380  are fluidly connected. However, in an exemplary embodiment, the action of pushing stem  200  in or inward I will force base top  247  against tube bottoms  332 , thus temporarily preventing fluid communication between chamber  460  and axial chambers  220  while medication M is being injected into the patient. 
     Substance  335  is a compound that will dissolve over a period of time after coming into contact with medication M, suspension media SM, and/or dried medication DM, such that preferably substance  335  dissolves within a predetermined time, such as within several minutes. 
     Turning back to  FIG. 2 , when chamber  460  and cavity  380  are in fluid communication, chamber  460  and axial chambers  220  are also in fluid communication. Accordingly, when stem  200  is pulled out or outward O, chamber  460  can be filled from air A that is within axial chambers  220 , thus preventing and/or interfering with compound C being pulled into chamber  460  via the tubular needle. In this situation, syringe  100  has been disabled and therefore syringe  100  is incapable of further use, and thus, incapable of assisting the further spread of communicable diseases and viruses. 
     It will be recognized that axial chambers  220  may be any configuration that allows for fluid communication between secondary channels  250  and atmospheric air that generally surrounds the outside of syringe  100 , such as, for exemplary purposes only, the atmospheric air disposed near depresser  230 . Similarly, it will be recognized that secondary channels  250  may be in any configuration that allows for fluid communication between chamber  460  and axial chambers  220 . Also similarly, it will be recognized that tubes  330  may be any configuration that allows for fluid communication between chamber  460  and axial chamber  220 .
