Description

Technical Field

[0001] This invention belongs to the field of medical tool technology, specifically relating to a drug nebulizer for clinical anesthetics. Background Technology

[0002] With the continuous development of medical technology, clinical anesthetic drug delivery methods are also being continuously optimized. Nebulized drug delivery has been gradually applied in the field of anesthesia due to its advantages such as rapid onset of action, controllable dosage, and good patient tolerance. However, existing nebulizers still have problems such as inconvenient operation, poor sealing, excessive drug residue, and easy accidental activation, which affect the safety and effectiveness of anesthetic drug delivery. Summary of the Invention

[0003] In view of the above-mentioned shortcomings in the prior art, the present invention provides a drug nebulization device for clinical anesthesia to solve the problems in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a drug nebulizer for clinical anesthesia, comprising a nebulizer, an integrally formed handle on the outer side of the nebulizer, a spray button and a water pump switch fixedly installed on the upper end face of the handle, an adjustment knob fixedly installed on the outer side of the nebulizer, a drug bottle threadedly connected to the lower end face of the nebulizer, a miniature water pump, a battery and an inclined plate fixedly installed at the bottom of the inner cavity of the drug bottle, and the battery being electrically connected to the miniature water pump, and a charging port for charging being provided on the outer side of the battery; a first through hole matching the diameter of the input end of the miniature water pump is provided at the lower end of the inclined plate, the input end of the miniature water pump is connected to the first through hole through a threaded connector, the output end of the miniature water pump is connected to the inlet end of a water suction pipe, and the output end of the water suction pipe passes through a pre-set second through hole on the inclined plate and is connected to the input end of the nebulizer; an elastic hose is connected to the output end of the nebulizer, and an nebulizing nozzle for administering medication to the patient is connected to the end of the elastic hose.

[0005] Furthermore, the circumferential sidewall of the handle is provided with anti-slip texture.

[0006] Furthermore, the medicine bottle is made of medical transparent plastic, and its outer surface is provided with capacity markings.

[0007] Furthermore, the threaded connection between the sprayer and the medicine bottle is provided with a silicone sealing ring to enhance the sealing performance, and a threaded lock to prevent the connection from loosening.

[0008] Furthermore, the water pump switch is a push-button micro switch, which is triggered only when the pressing force reaches 5N to 8N, to avoid starting by slight touch.

[0009] Furthermore, both ends of the elastic hose are provided with rigid connectors with external threads, and the output ends of the atomizing nozzle and sprayer are provided with internal threads that match the rigid connectors.

[0010] Furthermore, medical silicone sealing rings are respectively embedded inside the first through hole and the second through hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The invention features an ergonomically designed one-piece handle with anti-slip texture that enhances grip stability, facilitating one-handed operation by medical staff. Furthermore, the water pump switch requires a certain amount of pressure to activate, effectively preventing accidental operation. This invention utilizes the suction power of a miniature water pump to efficiently extract medication from the bottom of a medicine bottle. Combined with a slant plate, the medication can be collected at the input end of the miniature water pump, greatly reducing medication residue. Furthermore, by adjusting the knob and the water pump switch, medical personnel can precisely control the start and stop of the miniature water pump and the flow rate, thereby achieving on-demand and precise dosage, greatly improving the safety and reliability of medication administration. The present invention uses a transparent medical plastic bottle with graduations for easy observation of the remaining liquid and for cleaning and replacement. It also uses a medical silicone sealing ring and a threaded locking structure to improve the sealing performance of the device and prevent the liquid from being contaminated and wasted.
