Description

Technical Field

[0001] The utility model belongs to the technical field of anesthesia equipment, and in particular relates to a nerve block anesthesia positioning device. Background Art

[0002] Anesthetics refer to drugs that can cause temporary and reversible loss of sensation and pain in the entire body or a part of the body. According to their range of action, they can be divided into general anesthetics and local anesthetics. Nerve block anesthesia is the injection of local anesthetics near the peripheral nerve trunk, which anesthetizes the area controlled by the nerve by blocking the conduction of nerve impulses.

[0003] Injecting local anesthetics around nerve trunks, plexuses, and ganglia to block impulse conduction and produce anesthesia in the area controlled is called nerve block. Nerve block only needs one injection to obtain a larger anesthesia area. Anesthesia is a variety of methods used during surgery or diagnostic examinations to eliminate pain, ensure patient safety, and create good surgical conditions. It is also used to control pain.

[0004] During anesthesia, the anesthetic solution needs to be injected into different positions and at different angles; however, the existing anesthesia injection devices have specific injection angles and cannot adjust the injection angle according to the needs of the injection, which affects the use during anesthesia.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figures 1 to 5 As shown, the embodiment of the utility model provides a nerve block anesthesia positioning device,

[0024] The utility model comprises a positioning seat 1, on which a rotating cylinder 2 rotatably connected thereto is provided, an angle locking structure 3 for locking is provided between the rotating cylinder 2 and the positioning seat 1, a lifting positioning structure 4 which is slidably matched therewith is provided inside the rotating cylinder 2, an anesthetic needle 5 is provided on the lifting positioning structure 4, and the anesthetic end of the anesthetic needle 5 is located between the lifting positioning structure 4 and the positioning seat 1 during operation.

[0025] When in use, after the anesthetic needle 5 is locked on the lifting and positioning structure 4 in the rotating cylinder 2, the position of the anesthetic needle 5 can be driven to move by the up and down movement of the lifting and positioning structure 4, thereby changing the up and down distance of the anesthetic needle 5 so that the anesthetic needle 5 can be extended downward when in use, and the anesthetic needle 5 can be moved out of the rotating cylinder 2 for anesthetic operation. When not in use, the anesthetic needle 5 can be protected and hygienically protected. The depth of injection of the anesthetic needle 5 into the patient can also be controlled by the downward rotation of the lifting and positioning structure 4 during anesthesia. The rotating cylinder 2 can be rotated at an angle on the positioning seat 1. When rotating, the angle of rotation can be observed and locked by the angle locking structure 3. Anesthetic operation can be performed at a specific position during anesthesia. After the angle is determined, the anesthetic needle 5 can be operated by the lifting and positioning structure 4 to perform anesthesia on the patient.

[0026] Specifically, the angle locking structure 3 includes a locking screw 31, which is horizontally arranged on one end of the rotating cylinder 2.

The lifting rod 43 can ensure the accuracy of the position of the lifting circular plate 41 when it moves up and down. The movement of the lifting circular plate 41 can move the anesthetic needle 5 out of the rotating cylinder 2, move the anesthetic needle 5 to the patient, and perform anesthesia on the patient. When injecting anesthesia, the number of rotations of the rotating knob 47 can also be controlled to accurately control the depth of the anesthetic needle 5 injected into the patient's skin. When not in use, the anesthetic needle 5 can be recovered into the rotating cylinder 2, thereby protecting the anesthetic needle 5 and preventing external pollution from affecting the cleanliness of the anesthetic needle 5.

[0030] Specifically, a mounting cylinder 45 is provided on the lifting circular plate 41, and the mounting cylinder 45 moves up and down in the rotating cylinder 2. A mounting notch is provided at the upper end of the mounting cylinder 45, and a locking screw 46 for locking the anesthetic needle 5 is provided on the mounting notch; the anesthetic needle 5 can be placed in the mounting cylinder 45, and then the anesthetic needle 5 can be locked in the position in the mounting cylinder 45 by rotating the locking screw 46, and it will not change during the anesthetic injection.
