Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia equipment, and more particularly, to a quantitative spray anesthesia device for laryngeal anesthesia. Background Art

[0002] Sore throat often occurs easily after tracheal intubation under general anesthesia, which is related to multiple factors, especially local dryness caused by intubation movement and fasting. In the past, we used lidocaine gel to coat the tracheal tube cuff to reduce this adverse reaction in patients. In addition, local dryness caused by the inability to fast and drink water early after surgery is also one of the reasons for laryngeal pain, but excessive drinking will also bring adverse reactions such as choking and even aspiration and regurgitation.

[0003] The existing spray anesthesia devices have a single structure and cannot adapt to accurately quantify anesthesia for different patients' anesthesia sites, and the spray is difficult to evenly cover all the sites to be anesthetized. At the same time, the anesthesia operation requires a high level of proficiency from medical staff. It is necessary to avoid the drug from entering the airway by mistake, and the patient also needs to control breathing during spraying, making the anesthesia difficult.

[0004] In view of this, we now propose a quantitative spray anesthesia device for laryngeal anesthesia to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a quantitative spray anesthesia device for laryngeal anesthesia, which has a simple structure and is easy to use, and can accurately and quantitatively perform spray anesthesia on the laryngeal region.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A quantitative spray anesthesia device for laryngeal anesthesia includes an insertion tube and a quantitative mechanism. The insertion tube is provided with a nozzle and two isolation sacs, and the nozzle is arranged between the two isolation sacs. A first filling tube is arranged in the insertion tube and is connected to the isolation sac. The insertion tube is provided with a liquid outlet tube connected to the nozzle.

[0007] Further, in an embodiment of the present invention, the above nozzle includes an atomizing nozzle, and filling plates are arranged on both sides of the atomizing nozzle, and the filling plates are provided with second filling tubes.

[0008] Further, in an embodiment of the present invention, the above nozzle is provided with a groove, the filling plates are arranged in the groove, and the filling plates are arranged in an arc shape bent toward the atomizing nozzle.

[0009] Further, in an embodiment of the present invention, the above insertion tube is arranged in an "L" shape.

[0010] Further, in the embodiment of the present invention, an annular groove is provided on the insertion tube, and the spray head is slidably connected to the annular groove; an annular bevel gear is provided inside the spray head, a control rod is provided inside the insertion tube, threads are provided on the outside of the control rod, and the threads are engaged with the annular bevel gear.

[0011] Further, in the embodiment of the present invention, scale lines are provided on the control rod.

[0012] Further, in the embodiment of the present invention, the metering mechanism includes a metering tube, one end of the metering tube is connected to the liquid outlet tube, and a push rod is provided at the other end; a limit ring is threadedly connected to the outside of the metering tube, a resisting rod is provided on the outside of the push rod, and the resisting rod abuts against the limit ring.

[0013] Further, in the embodiment of the present invention, the diameters of the upper and lower ends of the isolation bladder are larger than the diameter of the middle part thereof.

[0014] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: Most of the existing open tongue retaining devices simply push aside the tongue body, and cannot control the tongue body well, resulting in poor working effects. This application provides a quantitative spray anesthesia device for throat anesthesia, which includes an insertion tube and a metering mechanism. A spray head and two isolation bladders are provided on the insertion tube, and the spray head is arranged between the two isolation bladders; a first filling tube is arranged inside the insertion tube, and the first filling tube is connected to the isolation bladder; the insertion tube is provided with a liquid outlet tube connected to the spray head.

[0015] In the present invention, by providing two isolation bladders on the insertion tube, medical staff can, after sending the spray head on the insertion tube to the designated anesthesia position of the patient, fill the isolation bladders through the first filling tube, so that the two isolation bladders can form a relatively closed space, preventing the sprayed anesthetic from entering the trachea, and can be fully concentrated at the predetermined position, realizing precise spray anesthesia. At the same time, the limit ring threadedly connected to the outside of the metering tube, through the abutting of the resisting rod against the limit ring, enables precise metering for each spray anesthesia.

[0022] Most of the existing tongue-opening devices are simply used to push aside the tongue body, and cannot well control the tongue body, resulting in poor working effects. By providing two isolation bladders 8 on the insertion tube 1, the present invention enables medical staff to fill the isolation bladders 8 through the first filling tube 2 after sending the nozzle 6 on the insertion tube 1 to the specified anesthesia position of the patient, so that the two isolation bladders 8 can form a relatively closed space, avoiding the sprayed anesthetic from entering the trachea and being fully concentrated at the predetermined position, realizing precise spray anesthesia. At the same time, the limit ring 13 threadedly connected to the outside of the metering tube 12 abuts against the limit ring 13 through the contact rod 15, enabling precise metering for each spray anesthesia.

[0023] Furthermore, in the embodiment of the present invention, the nozzle 6 includes an atomizing nozzle 9. Filling plates 10 are arranged on both sides of the atomizing nozzle 9, and a second filling pipe 3 is arranged on the filling plate 10. The arrangement of the filling plates 10 can further limit the spraying direction of the atomizing nozzle 9. It can be understood that the atomizing nozzle 9 can be set with a common structure on the market.

[0024] Furthermore, in the embodiment of the present invention, a groove 11 is arranged on the nozzle 6, the filling plate 10 is arranged in the groove 11, and the filling plate 10 is arranged in an arc shape bent towards the atomizing nozzle 9. The filling plate 10 arranged in the groove 11 is convenient to enter the throat when not filled. Both the filling plate 10 and the isolation bladder 8 can limit the throat to prevent the spray from entering the trachea.

[0025] Furthermore, in the embodiment of the present invention, the insertion tube 1 is arranged in an "L" shape. The insertion tube 1 arranged in an "L" shape can enter the throat well.

[0026] Furthermore, in the embodiment of the present invention, an annular groove is arranged on the insertion tube 1, and the nozzle 6 is slidably connected to the annular groove; an annular bevel gear 7 is arranged inside the nozzle 6, a control rod 5 is arranged inside the insertion tube 1, threads are arranged on the outer side of the control rod 5, and the threads are meshed with the annular bevel gear 7. The cooperation of the threads and the annular bevel gear 7 enables medical staff to control the rotation of the annular bevel gear 7 by pulling the control rod 5, thereby adjusting the direction of the nozzle 6.

[0027] Furthermore, in the embodiment of the present invention, scale lines are arranged on the control rod 5. The scale lines arranged on the control rod 5 are convenient for medical staff to determine the orientation of the atomizing nozzle 9.
