Description

Technical Field

[0001] The utility model relates to the technical field of intubation puncture needles, in particular to a carotid artery retrograde guided tracheal intubation puncture needle. Background Art

[0002] Establishing an effective airway to ensure airway patency is one of the important duties of anesthesiologists. Tracheal intubation is the most important solution for establishing airway. At present, after the failure of conventional tracheal intubation methods in patients with difficult airway, there is still no method that can achieve a 100% success rate of tracheal intubation. Retrograde tracheal intubation was first used clinically by Butler and Cirillo in 1960. It should become a tracheal intubation method that anesthesiologists are familiar with and master in the treatment of difficult airway and emergency airway. Retrograde intubation generally refers to using a puncture needle to puncture the cricothyroid membrane, and then inserting a guide wire into the respiratory tract through the puncture needle to the head, so that the guide wire passes retrograde through the glottis to the oral cavity or nasopharyngeal cavity, and then pulls them out of the mouth or nostril with fingers or intubation forceps / tweezers. After that, the tracheal tube is put on the outside of the guide wire, and the tracheal tube is inserted into the trachea through the glottis with the guide wire as a guide. The main advantages of retrograde endotracheal intubation are: simple operation, easy to master; the required instruments are common and easy to obtain; safe and effective; short time consumption. Therefore, mastering the retrograde endotracheal intubation technique can be used as an option in emergency situations, especially in primary hospitals with scarce medical resources.

[0003] There is a tracheal puncture needle CN219331831U, which includes a syringe, a piston is slidably connected inside the syringe, one end of the piston is fixedly connected to a piston handle, one end of the syringe is provided with a nipple, one end of the syringe is threadedly connected to an adapter on the side wall of one end of the syringe, the nipple is located in the adapter, the adapter is connected to a cylindrical barrel through a sliding device, a sealing device is provided on the side wall of the cylindrical barrel, one end of the cylindrical barrel is threadedly connected to a needle bolt, one end of the needle bolt is fixedly connected to a needle stem, and one end of the needle stem is provided with a needle tip. The utility model can fix the needle bolt on the syringe by providing an adapter, a sliding device and a sealing device, and the operator does not need to manually fix the needle bolt during operation, which solves the safety hazard of the needle bolt falling off;

[0004] The existing puncture needle needs to be assembled before use, but the puncture needle still needs to be placed in the air for a period of time after assembly, which may cause contamination of the puncture needle. In order to solve the above problem, a carotid artery retrograde guided tracheal intubation puncture needle is proposed. Utility Model Content

The piston is arranged in the syringe, the connecting ring is arranged on the syringe, the needle is arranged in the connecting ring, the protective sleeve is arranged on the connecting ring, the sliding groove is arranged on the protective sleeve, the sliding groove is arranged in the sliding sleeve, the limit baffle is arranged on the sliding sleeve, the placement groove is arranged on the sliding sleeve, the placement groove is arranged in the protective plate, and the tightening bolt is arranged on the protective plate;

[0006] Further, the piston is located inside the syringe, the needle is fixedly connected to the end of the syringe, the connecting ring is fixedly arranged at the end of the syringe, the needle is located inside the connecting ring, and the outer surface of the connecting ring has threads;

[0007] Furthermore, the inner wall of the protective sleeve is threaded, the protective sleeve is connected to the connecting ring through threads, the slide groove is located at the front end of the protective sleeve, the slide groove is an annular groove, a convex ring is provided at the outlet of the slide groove, and a convex ring is provided at the end of the slide sleeve;

[0008] Furthermore, a limit baffle is fixedly arranged at the front end of the sliding sleeve, and there are two limit baffles which are symmetrically arranged on the surface of the sliding sleeve. The placement groove is located at the front end of the sliding sleeve, and the bottom of the protective plate is semicircular. The protective plate is engaged with the placement groove, and the protective plate and the limit baffle are connected by tightening bolts.

[0009] Beneficial effects of the utility model:

[0010] The utility model moves the sliding sleeve along the sliding groove to the inside of the protective sleeve in sequence, the needle is exposed, the syringe is grasped and the piston is used to absorb the medicine, and when the medicine is absorbed, the limit baffle is grasped to pull out the sliding groove, and then the protective plate is inserted into the placement groove and fixed with a tightening bolt. When it is necessary to perform carotid artery retrograde guided tracheal intubation, the protective sleeve is unscrewed from the connecting ring through the thread to perform puncture work, thereby avoiding assembly during use, and at the same time, the protective sleeve and the sliding sleeve are used to wrap the needle to avoid the puncture needle from being contaminated in the air.
