Nozzle-type drug administration device applied to airway product

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a nozzle-type drug administration device applied to an airway product. The nozzle-type drug administration devicecomprises an upper cover and a lower cover, the upper cover comprises a spraying upper cover body at the top end and a straight upper cover body arranged at the bottom end; a nozzle hole is formed inthe top end of the spraying upper cover body, and an arc-shaped channel is formed in the spraying upper cover body; drug outlet grooves are formed in the two sides of the arc-shaped channel; the lower cover comprises a straight lower cover body arranged at the bottom end and a bulge arranged on the straight lower cover body; a drug outlet hole is formed in the straight lower cover body; the straight upper cover body is provided with a groove matched with the bulge; a gap is reserved between the groove and the bulge to form a flow guiding groove; and the drug outlet hole, the flow guiding groove, the drug outlet grooves, the arc-shaped channel and the nozzle hole sequentially communicate to form a drug administration channel. The nozzle-type drug administration device is simple in structure and convenient to use, accurate drug administration to the inside of the trachea of a patient during operation and before tube drawing is supported, and the pain of the patient is relieved.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a nozzle type drug delivery device applied to airway products. Background technique [0002] The most common airway products are tracheal intubation; tracheotomy; laryngeal mask; nasopharyngeal tube; bronchial intubation, etc. At present, the establishment of artificial breathing channel through the operation of airway products is the most effective, mature and commonly used technical means in first aid, patient rescue and nursing. However, this type of operation is more irritating to the patient when the catheter is inserted or pulled out, and often causes severe stress reactions in the patient. In clinical practice, local anesthetics are often applied on the surface of the catheter to reduce the stimulation to the patient. However, After the catheter is inserted, the local anesthetic cannot be reapplied, and the effect of the pre-applied local anesthetic will gradual...

Problems solved by technology

However, this type of operation is more irritating to the patient when the catheter is inserted or pulled out, and often causes severe stress reactions in the patient. In clinical practice, local anesthetics are often applied on the surface of the catheter to reduce the stimulation to the patient. However, After the catheter is inserted, local anesthetics cannot be applied again, and the efficacy of the pre-applied local anesthetics will gradually disappear. When the catheter is extubated, the strong stimulation will cause the patient's severe stress response, which will endanger the safety of the patient in severe cases.
