Description
Technical field
This utility model relates to medical instruments field, particularly a kind of hose type per nasal throat tunica mucosa tracheae anesthesia nebulizer.
Background technology
In clinical treatment, when carrying out tracheal intubation operation, bronchoscopy or treating, desirable, safe anesthesia is the guarantee of successful operation.Medical worker makes every effort to seek a kind of simple, reliable topical anesthesia method all the time.Current topical anesthesia method has thyrocricoid puncture method, aerosol rebreathing method, rinsing the mouth method, tracheal strips dripping method etc.Thyrocricoid puncture narcotization is respiratory mucosa topical analgesic effects the best way, but thyrocricoid puncture has wound to operate, and can cause infection, hemorrhage, damage, patient fears pain and is reluctant to accept more.So the anesthesia method usually adopted now is aerosol rebreathing method.
For the patient that the state of an illness is critical, medically sometimes need to carry out the operations such as tracheal intubation, but salvage grave patients all can not tolerate intravenous anesthetic induction usually (because intravenous injection anesthetics can cause hemodynamic unexpected change, such as blood pressure acutely raises/reduces, heart rate accelerates/slows down, even cardiac arrest etc.).In order to alleviate the stimulation of tracheal intubation, local surfaces anesthesia must be carried out to the throat tunica mucosa tracheae of patient, being all adopt anesthesia nebulizer usually, anesthetics being atomized, after patient is sucked, producing anaesthetic effect.
Have also some anesthesia nebulizers in the middle of prior art, but its nozzle bore of anesthesia nebulizer of routine is all the straight tube of hard metal, inflexible, patient's seat can only be used for and the patient of cooperation of dehiscing.And for bed patient, the patient that can not coordinate, unalive patient, they usually lip close to coordinate and dehisce, conventional anesthesia nebulizer cannot go directly pharyngeal.And this nozzle bore is that metal makes, and due to cost reason, cannot realize single use.So it is also a problem that the health of the anesthesia nebulizer of routine uses.
In addition, use conventional anesthesia nebulizer, the amount of anesthetics cannot be determined, if dose is too much, will liquid be produced, bronchus deep can be flowed into when the liquid of throat retention is more, easily cause patient to choke on the contrary to cough, the risk simultaneously also having anesthetics excessive.
Utility model content
The purpose of this utility model is to provide simple, the easy to use health of a kind of structure and can removes the hose type per nasal throat tunica mucosa tracheae anesthesia nebulizer of sputum/saliva.
According to an aspect of the present utility model, the hose type per nasal throat tunica mucosa tracheae that provides anesthesia nebulizer, it comprises syringe, flexible plastic pipe, rubber calm the anger ball, suction pump and atomising head;
Syringe comprises injection tube, push rod and mount pad, and injection tube is provided with scale, and push rod stretches into injection tube inside and seals mutually with the inwall of injection tube from one end of injection tube, mount pad is positioned at the other end of injection tube, and the inwall of mount pad is provided with female thread;
First passage, second channel, third channel and supporting-core is provided with in flexible plastic pipe, one end of first passage is provided with threaded connector, threaded connector is connected with mount pad, the other end of first passage is connected with atomising head, second channel and rubber ball of calming the anger is connected, third channel is connected with suction pump, and supporting-core is the tinsel that can bend, and flexible plastic pipe is provided with fin outside one end of syringe;
Rubber ball of calming the anger is connected with second channel, and rubber calms the anger ball for sending into air draught in second channel;
