Definitions
- the outer end of the radial protrusion is provided with a button.
- the pressure sensor, the pressure signal measuring circuit, and the display device described in the present invention Both the sound alerting device and the sound alerting device employ well known solutions in the prior art.
- the well-known technical solutions of the pressure sensor, the pressure signal measuring circuit, the display device and the sound prompting device are known to those skilled in the art, and are not described herein again.
- the side wall of the front end of the catheter is provided with a through hole, even if the front port of the catheter is blocked by soft tissue, the infusion of the drug solution can be ensured.
- the X-ray shielded wire inside the catheter helps to observe the position of the catheter under X-ray and to understand the injection.
- the inclined surface of the needle tip is at an angle of 45 degrees to the axial direction of the needle core.
- the circular section is used to facilitate the resistance when the sheath or fascia is broken.
- the needle core is not sharp and is not easy to damage the nerve. Clinical experiments have confirmed that when the anatomical positioning is accurate, the needle insertion method using the present invention is simple and easy to operate, and has less nerve damage. When the nerve is blocked, the resistance of different tissues can be utilized.
- the nerve block indwelling catheter needle of the measuring device comprises a needle core 6, a catheter 1 and a pressure detecting device, wherein the needle core 6 passes through the catheter 1, the front end of the needle core 6 is provided with a needle tip 61, and the needle tip 61 is extended Outside the front end face of the duct 1, at least one through hole 101 is disposed on the side wall of the front end of the duct 1, and a connecting tube 19 is fixedly connected to the tail end of the duct 1, and a peripheral sleeve of the joint of the tail end of the duct 1 and the connecting tube 19 is provided.
- the casing 20 is provided with a signal line connection socket 14, and the signal line 17 is provided with a connection plug 16, and the signal line connection socket 14 is mated with the connection plug 16.
- the circular section is used to facilitate the resistance when the sheath or fascia is broken.
- the needle core 6 is not sharp and is not easy to damage the nerve.
- Clinical experiments have confirmed that when the anatomical positioning is accurate, the needle insertion method using the present invention is simple and easy to operate, and has less nerve damage.
- the resistance changes of different tissues can be used to objectively and clearly indicate the position of the needle, especially when the needle is inserted into the sheath or under the fascia.
- the invention can simplify the operation steps, avoid nerve damage, save the expensive cost of purchasing the B-ultrasound, avoid the discomfort of the muscle twitch caused by the stimulator, and can also be used when the patient is fully sedated or combined with general anesthesia, and has important clinical significance. .
