Embodiment Construction

[0051] As previously mentioned, the reason why the cross-sectional dimension of the echogenic indwelling catheter is equal to or larger than the hollow needle is that the catheter can fill the space created by the needle to avoid backflow and / or leakage of the drug. Therefore, it may not be possible to insert the catheter into the hollow needle.

[0052] It is an object of the present invention to provide an echogenic indwelling catheter which is suitable for adjusting, readjusting and verifying the placement of the echogenic indwelling catheter in a patient. This is not only to improve the success rate of catheter placement in patients, but also to make postoperative pain management more effective.

[0053] In one embodiment of the invention, the drug is an anesthetic or any suitable drug, preferably a local anesthetic. The anesthetic may eg be selected from ropivacaine, bupivacaine, mepivacaine, lidocaine and / or any other local anesthetic.

[0054] In one embodiment of the...

Abstract

The present application relates to an echogenic indwelling catheter, an assembly and a method for medicating a patient with medication such as anaesthetics or other suitable drugs. In one embodiment, the echogenic indwelling catheter comprises a catheter shaft (1) comprising a bore (2), a plurality of radial holes (3) distributed along at least a part of said catheter shaft and configured for delivery of medication, a guidewire (5b) attached to and / or within the bore of the catheter and extending beyond a distal end of the catheter shaft.

Description

technical field [0001] The present invention relates to the administration of fluid medicine, especially analgesic treatment medicine, and more particularly relates to an indwelling catheter for fluid medicine administration. More particularly, the present invention relates to an echogenic indwelling catheter, assembly and method for administering, for example, an anesthetic or other suitable drug to a patient. Background technique [0002] During surgery, it may be desirable to insert a catheter in order to administer medication to a patient. For example, following a surgical procedure, it may be desirable to provide a patient with a continuous and / or intermittent flow of medication through a catheter for a period of time where pain may be present. [0003] A common procedure for administering a drug to a patient is to insert a hollow needle into the patient's body and insert a catheter through the needle. After insertion, the needle is retracted back, leaving the cathete...
