Fracturing conveying ground manifold system

The invention discloses a fracturing conveying ground manifold system. The fracturing conveying ground manifold system comprises a fracturing tree, a high-low pressure manifold device, a high-pressureflange conveying pipeline, a ground fracturing control manifold device, an offset flange mechanism and a corner pipeline, wherein the high-low pressure manifold device is linearly connected with theground fracturing control manifold device through the high-pressure flange conveying pipeline; the ground fracturing control manifold device is connected with the fracturing tree through the offset flange mechanism and the corner pipeline; and the offset flange mechanism and the corner pipeline can realize adjustment of different heights and directions between the ground fracturing control manifold device and the fracturing tree. The fracturing conveying ground manifold system has the advantages that the whole manifold system is large in displacement, simple in structure, simple in layout, fewin pipelines, few in joints, linear in conveying, relatively low in kinetic energy loss and capable of being separated from the ground, effectively prolonging the service life of the manifold, realizing multi-wellhead zipper type operation and improving the operation efficiency of a fracturing well factory.

Catheter assembly and sheath tear assistant tool

InactiveUS20070078438A1Easily inserted intoEasily indwelledMulti-lumen catheterBlood vesselCatheter device
A catheter a part which is inserted into and indwelled in a blood vessel by the Seldinger method and a sheath for covering the catheter are included. The catheter is constituted of a double lumen portion in which a first lumen and a second lumen are integrally formed in parallel with each other, a first branch tube and a second branch tube extended to the one side of the double lumen portion and an extension tube connecting portion provided to the other side of the double lumen portion. The inner cavity of the first branch tube communicates with the first lumen and the inner cavity of the second branch tube communicates with the second lumen. The distal end of the first branch tube is bulged in the vicinity thereof so as to slidably contact with the inside of the distal end of the sheath.

System and method of delivering local anesthesia

A catheter and introducer needle assembly is provided including a catheter adapter at its proximal end. The catheter adapter includes a side port in fluid communication with the catheter. A septum is located in the proximal end of the catheter adapter proximal of the side port. The introducer needle is connected at its proximal end to a needle hub and includes at least one notch formed therein in communication with the introducer needle lumen. The notch is formed in the needle such that blood can flow into the open distal end of the needle, through the lumen in the needle and through the notch into the catheter lumen (specifically, the annular space between the outside of the introducer needle and the inside of the catheter and catheter adapter). Thereafter, the blood can flow through the annular space and then through the side port and extension tube that extends from the catheter adapter. Similarly, liquids delivered to the side port flow to the annular space between the needle and the catheter, through the notch into the lumen within the needle, and out of the tip of the needle. Liquid anesthesia thus can be delivered to the patient's tissue surrounding the needle tip be delivering the liquid through the side port. An electrical connection may be provided to the needle via the needle hub to. carry an electrical charge to the patient's tissue. After withdrawing the needle from the catheter, the catheter remains in place, with the tip of the catheter disposed in the tissue being anesthetized. The clinician may provide additional anesthesia via the catheter through the extension tube set.

Power injection catheters and method of injecting

Power injection catheters for high flow rate delivery of fluids are disclosed. In one embodiment, a catheter may include a body defining one lumen and a plurality of extension tubes each comprising a lumen in fluid communication with the one lumen of the catheter body. Further, an extension tube may be configured for performing power injection and an extension tube may include a proximal valve. In another embodiment, a catheter may comprise a plurality of lumens and extension tubes, each of the extension tubes comprising a lumen in fluid communication with one lumen of the catheter body, respectively. At least one extension tube may be configured for performing power injection and at least one extension tube may include a proximal valve. Such catheters may include a pressure relief mechanism for preventing overpressurizing of the catheter. A method of injecting a fluid into a patient's body is disclosed.
