연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Systems for injecting fluids and/or other materials into a targeted anatomical location, in particular, an intra-articular space, include a handpiece assembly having a proximal end and a distal end, a needle extending from the distal end of the handpiece assembly, a fluid delivery module comprising a cassette and a fluid transfer device. A conduit is generally configured to place the fluid delivery module in fluid communication with the handpiece assembly. Medications, formulations and/or other fluids or materials contained within vials that are secured to the fluid delivery module can be selectively delivered into an anatomy through a needle located at the distal end of the handpiece assembly. In some embodiments, ultrasound or other imaging technologies can be used to locate a joint or other targeted anatomical location.

1. An imaging-guided anesthetic injection system comprising: a fluid delivery module comprising at least one loading area configured to receive a container containing an anesthetic, the at least one loading area being configured to securely receive various sizes and shapes of the container;at least one reservoir located within an interior of the fluid delivery module, wherein the at least one reservoir is configured to be placed in fluid communication with the container when said container is properly secured to the at least one loading area;wherein at least one slidably movable member is configured to be moved within or out of the at least one reservoir to selectively transfer a volume of the anesthetic from or to the at least one reservoir, wherein movement of the at least one slidably movable member relative to the at least one reservoir changes an effective volume of the at least one reservoir;wherein the at least one slidably movable member is configured to be moved using at least one motor;at least one conduit configured to be placed in fluid communication with the at least one reservoir, said at least one fluid conduit comprising a distal end;wherein the distal end of the at least one conduit is configured to removably receive a needle, said needle being configured to be placed within an anatomy of a subject for the subsequent delivery of the anesthetic through the at least one conduit and the needle;at least one controller configured to regulate at least one aspect of the delivery of the anesthetic from the fluid delivery module to a target anatomical location of the subject; anda display configured to provide status information related to the delivery of the anesthetic to the target anatomical location;wherein the system is configured to be placed in data communication with an imaging device to assist in accurately advancing the needle into the anatomy of the subject. 2. The injection system of claim 1, wherein the display is additionally configured to provide at least one real-time image obtained by the imaging device. 3. The injection system of claim 1, wherein the imaging device comprises an ultrasound device. 4. The injection system of claim 1, wherein the at least one controller comprises a foot pedal assembly. 5. The injection system of claim 1, wherein the at least one controller comprises one or more buttons. 6. The injection system of claim 1, wherein the system is configured to aspirate a volume of native bodily fluid from the anatomy of the subject at least partially through the needle. 7. The injection system of claim 6, wherein the system is configured to aspirate a volume of native bodily fluid from the anatomy of the subject by applying a negative pressure to the at least one conduit. 8. The injection system of claim 7, wherein the negative pressure within the at least one conduit is configured to be generated manually by the clinician. 9. The injection system of claim 7, wherein the negative pressure within the at least one conduit is configured to be is generated automatically using the fluid delivery module. 10. The injection system of claim 1, wherein the at least one loading area comprises a first loading area and at least a second loading area, wherein the first loading area is configured to receive the container containing the anesthetic, and wherein the second loading area is configured to receive a second container comprising a second fluid. 11. The injection system of claim 10, wherein the second fluid comprises at least one of an anesthetic and a non-anesthetic. 12. The injection system of claim 1, wherein the system is configured to detect a back-pressure associated with a delivery of the anesthetic through the at least one conduit. 13. The injection system of claim 1, wherein, during delivery of the anesthetic to the at least one conduit, the display is additionally configured to provide data relating to a back-pressure against which the anesthetic is being delivered. 14. The injection system of claim 1, wherein the target anatomical location of the subject is an area proximate a nerve. 15. An imaging-guided anesthetic injection system comprising: a fluid delivery module comprising at least one loading area configured to receive a container comprising an anesthetic, the at least one loading area being configured to securely receive various sizes and shapes of the container;at least one fluid reservoir within an interior of the fluid delivery module, said at least one fluid reservoir comprising at least one plunger, wherein movement of the at least one plunger within or out of the at least one reservoir changes an effective volume of the at least one reservoir;at least one conduit configured to be placed in fluid communication with the at least one fluid reservoir, said at least one conduit comprising a distal end, said distal end configured to receive a needle;wherein the fluid delivery module is configured to selectively transfer at least a portion of the anesthetic from the container through the at least one conduit via the at least one fluid reservoir;wherein the fluid delivery module comprises at least one motor, said at least one motor being configured to selectively move the at least one plunger to facilitate the transfer of the fluid from the container through the at least one conduit and to the needle;at least one controller configured to regulate at least one aspect of the delivery of the anesthetic from the fluid delivery module to a target anatomical location of the subject according to a delivery scheme; anda display configured to provide status information related to the delivery of the anesthetic to the target anatomical location;wherein the system is configured to be placed in data communication with an imaging device to assist in accurately advancing the needle into the anatomy of the subject;wherein the display is additionally configured to provide at least one real-time image of the anatomy of the subject obtained by the imaging device; andwherein the system is configured to detect a back-pressure associated with a delivery of the anesthetic through the at least one fluid conduit. 16. The injection system of claim 15, wherein the needle is secured to a distal end of a handpiece, said at least one conduit being at least partially routed through an interior of said handpiece. 17. The injection system of claim 15, wherein the imaging device comprises an ultrasound device. 18. The injection system of claim 15, wherein the at least one controller comprises a foot pedal assembly. 19. The injection system of claim 15, wherein the system is configured for aspiration of a volume of native bodily fluid from the anatomy of the subject proximally at least partially through the needle. 20. The injection system of claim 15, wherein the display is additionally configured to provide data or information relating to one or more of the following: the back-pressure associated with a delivery of the anesthetic through the at least one fluid conduit, a volume of the anesthetic delivered to the subject and a volume of the anesthetic remaining to be delivered to the subject.
