Puncture injection needle tube frame with dismounting, mounting and locking functions for pain department

Abstract

The invention relates to the technical field of medical instruments, in particular to a pain department puncture injection needle tube frame with dismounting, mounting and locking functions. Comprising a disposable needle tube, an injection needle frame and a locking assembly, the disposable needle tube comprises a needle head, a medicine tube, a fixed limiting disc, a rubber piston and a rubber seal, and the injection needle frame comprises a sleeve, a pressing sleeve, a pressing rod and a threaded sleeve connector. The quick release assembly comprises a first limiting gear disc, a first auxiliary separation buckle, a second limiting gear disc and a second auxiliary separation buckle, a first vertical sliding open groove allowing the first auxiliary separation buckle to vertically slide is formed in the threaded sleeve connector, and a third vertical sliding open groove allowing the second auxiliary separation buckle to be connected in a sliding mode is vertically formed in the sleeve. The bottom end of the pressing rod is provided with an abutting pressing base used for abutting against the rubber piston. The needle applying operation comfort is improved, the function of rapidly disassembling the disposable needle tube can be achieved, the working efficiency is improved, and the safety risk is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pain department puncture and injection needle tube rack with disassembly and locking functions. Background technique [0002] The minimally invasive techniques used in the pain department are mainly used in the treatment of intervertebral disc herniation, including collagenase, incision and suction, intervertebral discoscopy (PED), PLDD, ozone, IDET, radio frequency, ion knife, etc. In order for patients and doctors to better cooperate with treatment, it is necessary to anesthetize patients when performing minimally invasive surgery, so that patients can relieve pain and create good operating conditions for doctors. [0003] Usually, anesthesia is administered by using a disposable needle and a needle tube. In the prior art, most of the needles and needle tubes are snap-connected through a slot for quick insertion. However, in this way, the needle is inserted into t...

Problems solved by technology

[0003]Usually anesthesia uses a disposable needle and a needle tube to administer medicine. Insertion, however, the needle in this way is prone to shaking during insertion into the patient's skin, causing air bubbles to enter the interior of the needle through the connection between the needle and the needle, which may have serious consequences, such as Figure 1 and 4, the prior art also includes a disposable needle tube 1 installed on the injection needle holder 2, and the disposable needle tube 1 includes The needle 1a, the medicine tube 1b, the fixed limit disc 1c, the rubber piston 1d and the rubber seal 1e, the fixed limit disc 1c is fixedly installed on the side of the needle 1a close to the medicine tube 1b, and the fixed limit disc 1c is arranged coaxially with the needle 1a , the rubber piston 1d is set on the top of the medicine tube 1b, the rubber seal 1e is set on the bottom of the medicine tube 1b, the injection needle frame 2 includes a sleeve 2a, a pressure sleeve 2b, a pressure rod 2c and a threaded sleeve joint 2d, the sleeve 2a Set vertically, the pressing sleeve 2b is set on the top of the sleeve 2a, the pressing rod 2c is slidably arranged on the pressing sleeve 2b, the threaded sleeve joint 2d is fixedly installed at the bottom of the sleeve 2a, the medicine tube 1b is set in the sleeve 2a, fixed The limit disc 1c is arranged between the threaded sleeve joint 2d and the sleeve 2a, and the locking assembly 3 includes a compacted threaded sleeve 3a installed at the threaded sleeve joint 2d

[0004] Although the above-mentioned needle 1a is also inserted into the drug tube 1b in the way of insertion, but through the cooperation of the limit plate 1c and the compacting threaded sleeve 3a, the needle head has been greatly improved. 1a, and the injection needle holder 2 can be convenient for doctors to apply needles, improve work efficiency and injection accuracy, but the needle 1a of the above-mentioned device is not easy to pull out from the drug tube 1b after the disposable needle tube 1 is used up, and the anesthesiologist is dismantling it. When the needle 1a is connected to the medicine tube 1b, it is necessary to pull out the hand-held needle 1a or pull out the fixed limiter 1c by hand. Inserting the end of the used needle 1a into the hand of the anesthesiologist will cause a great safety hazard
