Description

Technical Field

[0001] The utility model relates to the technical field of anesthesia laryngoscopes, in particular to a convenient anesthesia laryngoscope surface anesthesia device. Background Art

[0002] In order to ensure the success rate of tracheal intubation, it is usually necessary to use a laryngoscope to check the patient's throat. Since the tracheal tube passes through the patient's throat, the patient is prone to vomiting due to sensitive stress, which is not conducive to the smooth progress of tracheal intubation. It is often necessary to use a laryngoscope to perform surface anesthesia on the patient's throat.

[0003] Existing laryngoscope surface anesthesia devices usually connect the nebulizer to the external anesthetic bottle, and promote the circulation of anesthetic liquid by pressing. The nebulizer atomizes the anesthetic liquid and sprays it on the patient's throat. However, when the liquid is pressed manually, the spraying of the anesthetic mist is affected by the pressing frequency, which makes the anesthetic spray operation inconsistent and affects the anesthesia efficiency. In addition, when pressing the spray, medical staff need to support the anesthetic bottle, and medical staff also need to support the laryngoscope equipment, which is inconvenient to operate.

[0004] In order to solve the above problems, patent CN202321137504.9 discloses a convenient surface anesthesia device for anesthesia laryngoscope. When the medical staff holds the operating tube to complete the placement of the laryngoscope, they press the push plate with their thumb to drive the push rod and the sealing gasket inside the medicine storage tank to move up and down, thereby performing the medicine pushing operation. After sufficient anesthetic solution is injected into the medicine storage tank, the push rod can be slowly pushed down once to allow the anesthetic solution to continuously and stably enter the nebulizer, thereby performing stable and continuous anesthetic mist spraying.

[0005] The following defects and shortcomings still exist in the implementation process: after the medicine in the medicine storage tank is used up, it needs to be manually injected, which is inconvenient to quickly add medicine at any time, and is not conducive to the continuous progress of the operation. In addition, the way of holding the operating tube by hand can easily cause the operating tube to slip and fall off in the hand, and the holding stability is not high. For this reason, we propose a convenient anesthesia laryngoscope surface anesthesia device. Utility Model Content
