Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a certain field, and specifically is a disposable laryngoscope drug spraying device. Background Art

[0002] In clinical practice, when the laryngoscope and / or the tube touches the throat or tracheal mucosa during endotracheal intubation, it will stimulate the throat and tracheal mucosa; this stimulation increases the activity of the sympathetic-adrenal system and the release of catecholamines in the body, leading to increased blood pressure, increased heart rate or arrhythmia. Usually, the above cardiovascular reactions are transient and short-lived, and will not cause a major impact on patients. However, for the elderly, especially those with hypertension, intracranial hypertension, heart disease, etc., it will have a more serious impact and affect the patient's life safety. Even ordinary patients do not want to have the above discomfort.

[0003] In order to solve the above problems, local lidocaine is often applied to the throat to reduce the cardiovascular stress response caused by endotracheal intubation. Currently, there is no special application device in the clinic, and the operation is usually completed using a 5ml syringe, which usually needs to be modified. In addition, there is a risk of the injection needle falling off or puncturing the patient's oral airway mucosa during the operation.

[0004] Therefore, there is a need for an instrument that can quickly complete local medication in the throat during intubation, specifically a disposable laryngoscope medication spraying instrument. Utility Model Content

[0009] During the operation, after the glottis is exposed, the spray tube is connected to the injection structure with medicine, and the medicine is pushed to the spray tube by controlling the injection structure, and the spray tube completes the application of medicine.

[0010] Furthermore, a spray head with a 360-degree spraying function is provided at the first end of the spray pipe, and this arrangement can realize all-round drug application to the throat. By applying the drug to the throat in the intubation space, effective drug application to the intubation stimulation area can be ensured.

[0011] Furthermore, a spray head is arranged at the first end of the spray pipe, and spray holes are arranged circumferentially along the side wall of the spray head at the first end of the spray head, and the spray holes are arranged spirally along the circumference of the first end of the spray head.

[0012] Alternatively, a spray head is provided at the first end of the spray pipe, a conical head facing inward is provided inside the first end of the spray head to disperse the direction of spraying the medicine, the tail end of the conical head is connected to the end of the first end of the spray head, and an arc-shaped spray port is provided at the periphery of the tail end of the conical head. In this way, 360-degree spraying of the medicine can also be effectively achieved.

[0013] Further, the spray tube only protects the drug application tube, and the first end of the drug application tube is flush with the end of the first end section of the laryngoscope setting tube.

[0014] Alternatively, the spray tube includes an outer soft tube and an inner drug application tube; a spray head is provided at the first end of the inner drug application tube; when the drug spraying is completed, the inner drug application tube is withdrawn, which can effectively avoid the interference and influence of the spray tube on the insertion action.

[0015] Technical Effects

[0016] The spray tube can be effectively installed by installing the spray tube to the extension plate corresponding to the intubation space or the second side wall plate of the laryngoscope installation tube, and the installation of the spray tube will not interfere with the installation of the laryngoscope blade.

[0017] By setting up a double-layer spraying tube, and setting the outer layer as an outer soft tube, it can be ensured that after the medicine is sprayed, the inner layer of the spraying tube is withdrawn, and the soft outer soft tube will not affect or interfere with the intubation action.

[0018] The 360-degree spray head is set up to ensure that the medicine is sprayed evenly on the throat area corresponding to the intubation stimulation area in the intubation space, which can avoid stimulation to the throat caused by subsequent intubation actions. BRIEF DESCRIPTION OF THE DRAWINGS
