Description

Novel nerve block needle

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to novel neural needle that blocks.

Background

In the field of disease diagnosis and treatment, the nerve block needle is widely used for treating diseases such as hemiplegia, body sensory disturbance, joint pain and the like, and in addition, when peripheral nerve block anesthesia is carried out, the nerve block needle can also be used for accurately determining the anesthesia position. The blocking needle under the ultrasonic guidance can clearly distinguish the positions of blood vessels, nerves, muscle tissues and puncture needles, directly blocks the nerves under the visual condition, is favorable for observing the peripheral structure of the nerves and dynamically observing the diffusion condition of the anesthetic, improves the accuracy and the success rate of nerve blocking, and reduces the injury of blood vessels and nerves related to operation. However, most of the existing nerve block needles can only be used for single administration and can not be used repeatedly.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel neural needle that blocks keeps somewhere through the bottom setting at the nook closing member, keeps somewhere that the head can disect insertion single joint of dosing, also is connected with the joint of dosing in succession simultaneously, can inject or dose in succession according to actual demand single during the use, and keeps somewhere that the head still is connected with neural stimulator and connects and can carry out neural stimulation, reduces the work load that the doctor carries out the puncture many times, reduces patient's pain, and reduces medical use cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel neural needle that stagnates, includes needle tubing, nook closing member, keeps somewhere head, nook closing member seat, single administration and connects and the joint of dosing in succession, the one end of needle tubing is equipped with the nook closing member and exports, and the other end is connected with keep somewhere the head, the bottom of nook closing member is connected with the nook closing member seat, its top by keep somewhere the head and alternate and go into the needle tubing, the lateral wall that keeps somewhere the head is connected with the joint of dosing in succession, the nook closing member seat is connected with the single is dosed and is connected.

Preferably, the indwelling head is further connected with a neurostimulator connector.

Preferably, the indwelling head comprises a cylindrical section and a conical section which is connected with the front end of the cylindrical section and is used for placing the puncture needle hole to seal the puncture needle hole, a penetrating single injection hole is arranged in the indwelling head, one end of the single injection hole is communicated with the needle tube, and the other end of the single injection hole is communicated with the single administration joint on the needle core seat.

Preferably, the single injection hole is internally provided with an anti-reflux device.

Preferably, a continuous injection hole is arranged in the indwelling head, one end of the continuous injection hole is communicated with the needle tube, and the other end of the continuous injection hole is communicated with the continuous administration joint.

After the technical scheme is adopted, compared with the background art, the utility model, have following advantage:

the utility model relates to a novel neural needle that hinders keeps somewhere through the bottom setting at the nook closing member, keeps somewhere that the head can the disect insertion single joint of dosing, also is connected with the joint of dosing in succession simultaneously, can inject or dose in succession according to actual demand single during the use, and keeps somewhere that the head still is connected with neural stimulator and connects and can carry out neural stimulation, reduces the work load that the doctor carried out the puncture many times, reduces patient's pain, and reduces medical use cost.
