When medical staff administer anesthesia to patients, the medication is usually sprayed into the patient's body through an anesthetic nozzle.

[0003] The nozzles on existing anesthesia spray heads are usually set in a straight line. Since the nozzles cannot rotate, medical staff cannot directly observe the throat when spraying anesthetic on the patient's throat, which causes the anesthetic to be sprayed off-center and reduces the effectiveness of the anesthetic. Therefore, we need to propose an anesthesia spray head assembly. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 -6. This utility model provides a technical solution: an anesthesia nozzle assembly, including a nozzle base 1, a squeeze pump head 2, and a fixing structure 3 for fixing the anesthesia nozzle; the nozzle base 1 is mounted on a liquid storage bottle 4, one end of the nozzle base 1 is provided with a connecting pipe 5, the other end of the nozzle base 1 is rotatably connected to a support pipe 6 via a rotating shaft, the support pipe 6 is connected to a liquid extraction pipe on the nozzle base 1, the end of the support pipe 6 is provided with a spray pipe 7, the outer surface of the spray pipe 7 is provided with a flipping component 8 for adjusting the angle of the spray pipe 7, the surface of the support pipe 6 is provided with a spray nozzle 9, and the spray nozzle 9 is connected to the spray pipe 7 via a flexible hose 10; the connection port of the squeeze pump head 2 is connected to the inner cavity of the connecting pipe 5, and the surface of the squeeze pump head 2 is provided with an adjustment structure 11 for adjusting the squeezing degree; the fixing structure 3 is mounted on the surface of the nozzle base 1, and the support pipe 6 is located in the inner cavity of the fixing structure 3.

[0026] Specifically, during use, the anesthetic is first placed into the storage bottle 4, and the nozzle base 1 is covered. Then, the squeeze pump head 2 is connected to the connecting pipe 5. By adjusting the setting of the adjustment structure 11, the support position of the squeeze pump head 2 trigger can be adjusted. By controlling the squeezing position of the squeeze pump head 2 trigger, the dosage of disinfectant sprayed can be adjusted. Then, the support pipe 6 is rotated, which drives the spray pipe 7 to rotate through the flipping component 8. After adjusting the position of the spray pipe 7, the support pipe 6 is fixed by the fixing structure 3. Then, the spray pipe 7 is flipped according to the position of the throat to adjust the angle of the spray pipe 7. This increases the adjustable range of the anesthetic nozzle, thereby avoiding the anesthetic nozzle from obstructing the vision of medical staff, preventing the anesthetic from being sprayed off-center, improving the anesthetic effect, and providing convenience for medical staff to spray anesthetic.

[0027] Preferred, such as Figure 6 As shown, the fixing structure 3 includes a fixing ring 31, which is fixedly connected to the outer wall of the nozzle base 1. A movable sleeve 32 is fixedly inserted into the top of the fixing ring 31. A movable rod is movably connected to the inner cavity of the movable sleeve 32. A fixing block 33 is fixedly connected to the bottom of the movable rod. A fixing groove 34 is opened on the outer surface of the support tube 6. Several sets of fixing grooves 34 are provided, and the sets of fixing grooves 34 are connected by sliding grooves. The surface of the fixing block 33 is engaged with the inner cavity of the fixing groove 34. Pushing the movable rod downward will cause the fixing block 33 to move and insert it into the inner cavity of the fixing groove 34. After engagement, the support tube 6 is prevented from rotating, and the adjusted position of the support tube 6 is fixed, increasing the stability of the support tube 6 after adjustment.

[0028] Furthermore, the top of the movable rod is rotatably connected to the support plate 12 via a pivot pin. A spring 13 is sleeved on the outer surface of the movable rod. The spring 13 is positioned between the movable sleeve 32 and the fixed block 33. The support rod supports the top of the movable rod, making it convenient for the operator to pull up the movable rod by hand. This allows the fixed block 33 to be quickly moved out of the inner cavity of the fixed groove 34 to release the support tube 6. When fixed, the spring 13 continuously pushes the fixed block 33 to move into the inner cavity of the fixed hole, improving the stability of the fixed block 33 after positioning with the fixed hole.

[0029] In addition, a ball bearing 14 is provided on the lower surface of the fixing block 33. The surface of the ball bearing 14 is slidably connected to the inner cavity of the slide groove. The ball bearing 14 allows the fixing block 33 to slide on the surface of the support tube 6. When the movable rod is released, the spring 13 pushes the fixing block 33 to move the ball bearing 14 into the slide groove. When the fixing block 33 does not enter the inner cavity of the fixing groove 34, it can continue to rotate, so that the ball bearing 14 drives the fixing block 33 to slide into the inner cavity of the fixing groove 34 through the slide groove, thus completing the fixation and providing convenience for the adjustment of the support tube 6.

[0030] Preferred, such as Figure 4 As shown, the flipping assembly 8 includes an adjustment frame 81, which is fixedly connected to the outer surface of the support tube 6. An adjustment groove 82 is provided on the surface of the adjustment frame 81, and an adjustment rod 83 is slidably connected to the inner cavity of the adjustment groove 82. The surface of the adjustment rod 83 is welded and fixed to the outer surface of the spray tube 7. The inner cavity of the adjustment frame 81 is rotatably connected to the outer surface of the spray tube 7 through a damping shaft. With the setting of the damping shaft, when the force exerted by the medical staff on the spray tube 7 is greater than the resistance of the damping shaft, the spray tube 7 can be flipped to adjust the angle of the spray tube 7. Through the cooperation of the adjustment groove 82 and the adjustment rod 83, the spray tube 7 can be assisted to flip in the inner cavity of the adjustment frame 81, thereby improving the stability of the spray tube 7 when flipping.

[0031] Specifically, Figure 5 As shown, the adjustment groove 82 is arc-shaped and there are two sets of adjustment grooves 82. The two sets of adjustment grooves 82 are symmetrically distributed on both sides of the adjustment frame 81. By setting the adjustment groove 82, the adjustable angle of the spray pipe 7 is limited, so as to avoid the hose 10 and the spray pipe 7 from getting tangled due to the excessive adjustment range of the spray pipe 7 angle.

[0032] Furthermore, such as Figure 2As shown, the adjustment structure 11 includes a support frame 111, which is fixedly connected to the handle of the extrusion pump head 2 and located between the handle and the trigger of the extrusion pump head 2. An adjustment hole 112 is formed on the surface of the support frame 111, and a metal pin 113 is slidably inserted into the inner cavity of the adjustment hole 112. An mounting hole 114 is formed on the inner sidewall of the support frame 111, and the surface of the metal pin 113 engages with the inner cavity of the mounting hole 114. Several sets of adjustment holes 112 are provided, and these sets of adjustment holes 112 are evenly distributed on the support frame 111. On surface 11, insert metal pin 113 into adjustment hole 112 and extend it into mounting hole 114. Metal pin 113 extends into the inner cavity of mounting hole 114 and engages with support frame 111 to limit the movement distance of trigger part of squeezing pump head 2. By adjusting the position of metal pin 113 on different adjustment holes 112, the movement distance of trigger part of squeezing pump head 2 is adjusted. By adjusting the degree of pressing of trigger part of squeezing pump head 2, the dosage of anesthetic liquid sprayed from spray tube 7 is controlled.

[0033] Specifically, such as Figure 3 As shown, a magnetic block 15 is provided in the inner cavity of the mounting hole 114. The surface of the magnetic block 15 is magnetically connected to the surface of the metal pin 113. The metal pin 113 is attracted by the magnetic block 15, which improves the stability of the metal pin 113 in the mounting hole 114 and prevents the metal pin 113 from falling out of the inner cavity of the mounting hole 114 when it is fixed.

[0034] In addition, the outer surface of the support frame 111 is provided with a dose line, and the positions of several sets of adjustment holes 112 correspond to the dose line. By setting the dose line, medical staff can quickly find the position of the adjustment hole 112 according to the required dose of anesthetic fluid, so as to facilitate the adjustment of the dose of anesthetic fluid spray.

[0035] Preferably, the reservoir bottle 4 is transparent, and the outer surface of the reservoir bottle 4 is provided with scale lines. Through the reservoir bottle 4 and the scale lines, medical staff can intuitively observe the dosage of the remaining anesthetic fluid in the reservoir bottle 4.

[0036] In practical use: First, add anesthetic solution to the reservoir bottle 4, then cover the anesthesia base and lock it to the reservoir bottle 4. Next, adjust the position of the metal pin 113 on the adjustment hole 112 according to the required dose of anesthetic solution to be sprayed. Insert the metal pin 113 into the inner cavity of the adjustment hole 112 and extend it into the inner cavity of the mounting hole 114 to magnetically connect with the magnetic block 15. Then connect the connection port of the squeeze pump head 2 to the connecting tube 5. Then, the medical staff holds the handle of the squeeze pump head 2 and presses the trigger to make the suction tube of the anesthesia base draw the anesthetic solution into the support tube 6. The support tube 6 is sent into the hose 10 through the spray nozzle 9. The hose 10 sends the anesthetic solution into the inner cavity of the spray tube 7 to achieve the spraying of anesthetic solution.

[0037] When spraying the patient's throat, the support plate 12 can be pulled upwards to move the movable rod upwards. The movable rod pulls the fixing block 33 out of the inner cavity of the fixing groove 34, releasing the support tube 6. Then, rotating the support tube 6 can drive the spray tube 7 to rotate. Adjusting the position of the support tube 6 by releasing the support plate 12 causes the spring 13 to push the fixing block 33 into the inner cavity of the fixing groove 34 to fix the position of the support tube 6. Then, the spray tube 7 can be adjusted to change the angle. This avoids obstructing the medical staff's view when spraying the patient's throat, avoids the anesthesia nozzle obstructing the medical staff's view, and avoids the anesthetic spraying position deviating, thus improving the anesthetic effect and providing convenience for medical staff in the anesthetic spraying work.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
