Abstract

A revolving multi-cartridge syringe device includes a needle and two or three revolving holders, each for receiving a cartridge containing medical fluid to be injected. The holders can be pre-loaded with the cartridges, with a first cartridge placed in a loaded position ready to dispense. After fluid in the first cartridge is injected into a patient, a second holder and cartridge are revolved into the loaded position, without breakdown of the syringe. The process can be repeated with a third cartridge. The engagement of each cartridge with the needle, retraction from the needle, and rotation of the revolving holder are all implemented by sliding a sliding actuator in either a first direction or a second, opposite, direction, depending on which action is desired. Thus, injection and reloading of the cartridges can be easily actuated by the user through manipulation of a single slidable actuator, without requiring withdrawing the needle from the mouth area to reload.

Claims

1. A syringe device, comprising:

a needle;

two or more holders each configured to receive a cartridge containing medical fluid to be injected;

a body unit coupled to the needle and the two or more holders and configured to receive one of the two or more holders in a loaded position at any one time;

a slidable actuator slidably coupled to the body unit; and

a revolving unit coupled to the body unit and the two or more holders, the revolving unit adapted to revolve the two or more holders one at a time into and out of the loaded position;

wherein the slidable actuator is configured in such a way as to engage the cartridge with the needle to effect fluid communication therebetween when the actuator slides in a first direction to an engagement position, disengage the cartridge from the needle when the actuator slides in a second direction opposite the first direction to a dis-engagement position, and revolve the revolving unit when the actuator slides additionally in the second direction beyond the dis-engagement position to a revolve position.

2. The syringe device of claim 1, wherein the needle is a standard disposable needle secured to and through a hub.

5. The syringe device of claim 1, wherein the revolving unit further comprises a cog having a grooved track in an exterior surface of the cog, the grooved track of the cog engages a pin on the two or more holders to enable the revolving of the two or more holders as the pin travels along the grooved track.

6. The syringe device of claim 5, wherein the grooved track comprises two or more curved peaks positioned at equal intervals around the cog.

7. The syringe device of claim 1, wherein the slidable actuator further comprises an engagement member that engages the cartridge in one of the holders in the loaded position.

8. The syringe device of claim 7, wherein the engagement member is a latching member.

9. The syringe device of claim 7, wherein the engagement member is a pushing member.

10. The syringe device of claim 1, further comprising a finger handle forming a portion of the actuator configured in such a way as to enable engagement of the actuator with a single finger or thumb of a user.

11. The syringe device of claim 10, wherein the finger handle is O-shaped.

3. The syringe device of claim I, wherein the body unit further comprises a guide member coupled to a backing piece for receiving one of the two or more holders in the loaded position.

4. The syringe device of claim 3, wherein a portion of the slidable actuator is situated in the guide member in such a way that the slidable actuator slides in the first direction and second direction relative to the guide member.

12. A syringe device, comprising:

a needle;

three or more holders each configured to receive a cartridge containing medical fluid to be injected;

a body unit coupled to the needle and the three or more holders and configured to receive one of the three or more holders in a loaded position at any one time;

a slidable actuator slidably coupled to the body unit; and

a revolving unit coupled to the body unit and the three or more holders, the revolving unit adapted to revolve the three or more holders one at a time into and out of the loaded position;

wherein the slidable actuator is configured in such a way as to engage the cartridge with the needle to effect fluid communication therebetween when the actuator slides in a first direction to an engagement position, disengage the cartridge from the needle when the actuator slides in a second direction opposite the first direction to a dis-engagement position, and revolve the revolving unit when the actuator slides additionally in the second direction beyond the dis-engagement position to a revolve position.

13. A method of using a syringe device, comprising:

providing two or more cartridges containing medical fluid;

engaging, using a slidable actuator, one of the two or more cartridges in a loaded position with a needle to effect fluid communication between the needle and the cartridge in the loaded position;

injecting, using the slidable actuator, the medical fluid contained in the cartridge in the loaded position, into a targeted tissue location;

disengaging, using the slidable actuator, the cartridge in the loaded position from the needle; and

revolving, using the slidable actuator, a revolving unit to cause the cartridge in the loaded position to be revolved out of the loaded position and to cause another cartridge of the two or more cartridges to be revolved into the loaded position.

14. The method of claim 13, wherein the step of engaging further comprises sliding the slidable actuator in a direction toward the needle.

15. The method of claim 13, wherein the step of disengaging further comprises sliding the slidable actuator in a direction away from the needle to a dis-engagement position.

16. The method of claim 15, wherein revolving further comprises sliding the slidable actuator additionally in the direction away from the needle beyond the dis-engagement position to a revolve position.

17. The method of claim 13, wherein the revolving unit further comprises a cog having a grooved track in an exterior surface of the cog configured in such a way that the grooved track of the cog engages a pin on two or more holders, receiving the two or more cartridges, to cause the revolving of the two or more cartridges as the pin travels along the grooved track.

18. The method of claim 17, wherein the pin reaches a valley in the grooved track causing one of the two or more holders to revolve into the loaded position.
