Abstract

A pressure sleeve assembly and a method of its use in a fluid injection system are disclosed. The pressure sleeve assembly includes a longitudinal base member, an endplate associated with the longitudinal base member, a fixed or freely removable door, a cylinder and a pivotal arm coupling the cylinder to the longitudinal base member. The pressure sleeve assembly includes properties that increase the ease of use and maintenance of the assembly so as to reduce the effort required by the user and increase the biosafety aspect of the assembly. In addition, the pressure sleeve assembly includes properties that reduce the amount of effort required by the physician prior to and during use of the system as well as properties that increase its range of applications.

Claims

1. A device for injecting fluid into a patient comprising:

an injector head;

a syringe sized to be placed into said injector head;

a receptacle area on said injector head sized to receive said syringe;

a cylinder having an opening sized to receive said syringe; and

,

said cylinder being connected to said injector head and being selectively rotatable on said injector head into and out of said receptacle area.

2. A device as set forth in claim 1, further comprising:

a longitudinal base member located at one end of said injector head;

said longitudinal base member containing said receptacle area and said cylinder being attached to said longitudinal base member.

3. A device as set forth in claim 2, further comprising a forward plate mounted on said longitudinal base member at a location forward of said receptacle area.

4. A device as set forth in claim 2, further comprising an attachment plate for connecting said longitudinal base member to said injector head, said attachment plate positioned at a location rearward of said receptacle area.

5. A device as set forth in claim 3, wherein said forward plate includes a slot for receiving a portion of said syringe.

6. A device as set forth in claim 5, wherein said slot receives an exit port of said syringe.

7. A device as set forth in claim 1, wherein said cylinder includes a slot for receiving a portion of said syringe.

8. A device as set forth in claim 7, wherein said slot is sized to receive a fluid inlet stem of said syringe.

9. A device as set forth in claim 3, wherein said forward plate includes a sensor device positioned to sense an operating parameter of said device.

10. A device as set forth in claim 9, wherein said sensor is a pressure sensor.

11. A device for injecting fluid in to a patient comprising:

an injector head;

a syringe sized to be placed into said injector head;

a receptacle area on said injector head sized to receive said syringe; and

a detachable door positioned at one end of said receptacle area.

12. A device as set forth in claim 11, wherein said detachable door includes a slot for receiving a portion of said syringe.

13. A device as set forth in claim 12, wherein said portion of said syringe is an exit port of said syringe.

14. A device as set forth in claim 11, wherein said detachable door includes a sensor for monitoring an operating parameter of said device.

15. A device as set forth in claim 14, wherein said sensor is a pressure sensor.

16. A device as set forth in claim 11, wherein said detachable door includes a grasping surface.

17. A method of injecting fluid into a patient comprising:

providing an injecting device;

providing a syringe for insertion into the syringe;

rotating a pressure sleeve out of a receptacle area of said injecting device;

inserting said syringe into said pressure sleeve assembly;

rotating said pressure sleeve into said receptacle area of said injecting device; and

,

performing a fluid injection into a patient.

18. A method according to claim 17, including filling said syringe with said fluid after rotating said pressure sleeve into said receptacle area.

19. A method according to claim 17, wherein said step of inserting includes placing a portion of said syringe into a slot on said pressure sleeve.

20. A method according to claim 17, wherein a portion of said syringe is rotated into a slot of located near said receptacle area as said pressure sleeve is rotated into said receptacle area.

21. A method according to claim 18, further including sensing an operating parameter of said injecting device.

22. A method according to claim 21, wherein said operating parameter is pressure being exerted by said fluid in said syringe.
