Technical Field
The invention relates to a visual laryngoscope for airway surface anesthesia.
Background
The trachea cannula is the basic technology for implementing general anesthesia, freeing respiratory tract and realizing respiratory support. According to the traditional view, the stimulation intensity in the tracheal intubation process is larger than the pain stimulation intensity of skin cut by a scalpel, sympathetic and parasympathetic nerve excitation is caused by tracheal intubation stimulation, severe fluctuation of hemodynamics of a patient is easily caused, and cardiovascular and cerebrovascular bleeding accidents are easily caused. However, after the intubation is finished, the narcotic sedative and analgesic drugs still have continuous action in vivo, so that the blood pressure, the heart rate and the cardiac output are usually reduced obviously after the intubation is finished, the phase becomes the high-incidence period of the cardiovascular and cerebrovascular infarction, and the risk of cardiovascular and cerebrovascular accidents is increased for patients with heart diseases, hypertension, advanced age or circulatory failure.
The trachea cannula technology combining general anesthesia with airway surface anesthesia is a trachea cannula technology which can be carried out by combining a small amount of general anesthesia medicine under sufficient airway surface anesthesia, and has the advantages of small circulation fluctuation in the cannula inserting period, small dosage of the general anesthesia medicine, reduction of side reaction of the medicine and less anesthesia complication. The local anesthetic is sprayed to the oral cavity, glottis, main bronchus and other parts before trachea intubation to perform surface anesthesia, complete inner surface anesthesia of the oropharynx, the larynx and the trachea can inhibit sympathetic nerve reflection during trachea intubation, the local anesthetic is absorbed by the oropharynx respiratory tract and the tracheal mucosa to stabilize nerve cell membranes, inhibit generation and conduction of nerve impulse, effectively reduce generation and transmission of damage stimulation of the trachea intubation, and fundamentally inhibit reaction of sympathetic adrenal medulla. The tracheal intubation stimulation intensity can be greatly reduced, further the severe fluctuation of blood pressure and heart rate in the intubation period is reduced, the dosage of general anesthesia medicines in the anesthesia induction period is reduced, the adverse reaction and complication rate of the medicines are reduced, and the occurrence of cardiovascular and cerebrovascular accidents is reduced (the reference document is Xuru seal, tetracaine endotracheal surface anesthesia and clinical observation for preventing cardiovascular side reactions of the tracheal intubation [ J ] clinical anesthesia journal, 2004(06):369.
The invention relates to a visual laryngoscope for surface anesthesia, which is medical equipment for implementing surface anesthesia of an oral cavity, a glottis, a main bronchus and the like.

From prior art, the equipment and apparatus for laryngeal anesthesia of present need use watering can or spray tube under the laryngoscope is supplementary, carry out the anesthesia of oral cavity and pharyngeal cavity to the waking patient, need both hands operation cooperation in addition also make the operating time extension of surface anesthesia, intensity of labour is big, require high to operator's operation experience, this process is lengthy, painful, and often difficult to carry out sufficient accurate anesthesia to deep structures such as epiglottis, glottis, trachea, often need to unite the effect of trachea cricothyroid membrane puncture anesthesia in order to reach the anesthesia around the glottis. Clinically, a laryngoscope which is convenient to operate, has a definite surface anesthesia effect and good tolerance of a patient and can carry out direct-view lower surface anesthesia on glottis and the following deep tissues is urgently needed.
At present, the visual laryngoscope used in clinic does not have the function of spray surface anesthesia, a clinician needs to use additional spraying equipment such as a spray can, a spray pipe, an injector and the like to match with the laryngoscope to carry out airway surface anesthesia, and needs to operate by two hands, and the spray position is not exact; in addition, the spraying effect, the spraying distance and the droplet size of additional spraying equipment such as a watering can, a spraying pipe, an injector and the like are influenced by the using strength of an operator, the situations of insufficient anesthesia or local anesthetic poisoning caused by excessive anesthesia often occur, and the optimal spraying effect can be mastered only by repeated practice; additional spraying equipment such as a watering can, a spray pipe, an injector and the like are difficult to perform sufficient anesthesia on deep structures such as epiglottis, glottis, trachea and the like due to structural reasons; most of the traditional extra-spray equipment is recycled, and repeated application increases the risk of cross infection of patients. In addition to the equipment problems, the drugs required for topical anesthesia also need to be dispensed separately, wasting valuable treatment time.

Discloses a visual laryngoscope with an anesthesia function, which comprises a handle, a display, a laryngoscope lens and a liquid storage part. The display is arranged at one end of the handle. The laryngoscope piece sets up in the other end of handle, prescribes a limit to the passageway in the laryngoscope piece, and the one end that is close to the handle of laryngoscope piece is equipped with the interface, and the one end of keeping away from the handle of laryngoscope piece is equipped with injection portion, and interface and injection portion communicate with the both ends of passageway respectively.
The visible laryngoscope with the anesthesia function has the functions of both the visible laryngoscope and the laryngeal anesthesia, and can monitor the anesthesia part through the laryngoscope during anesthesia, so that the anesthesia accuracy is improved, and the anesthesia effect is improved; the laryngoscope lens conforms to the anatomical structure of a human body and is suitable for extending into the throat, and the channel for conveying the anesthetic liquid is placed in the laryngoscope lens, so that the laryngoscope lens can easily extend into the throat along with the laryngoscope lens, and the anesthesia process is easy to operate. However, the liquid storage part of the device adopts a syringe for injecting medicine, and the injection of the medicine by using the syringe depends on manual injection, so that the operation is complicated; the spraying effect, the spraying distance and the droplet size are influenced by the use strength of an operator, the spraying effect is unstable, the situations of insufficient anesthesia or local anesthetic poisoning caused by excessive anesthesia often occur, and the optimal spraying effect can be mastered only by repeated practice; the liquid storage part, the interface part and the injection part of the device are connected through the channel, the channel is easy to block after repeated use, liquid medicine is remained in the channel, bacteria are bred in the channel, and the risk of cross infection of patients is increased; the injection part 33 of the device is exposed outside the lens, and sputum, blood and secretion of a patient have the possibility of polluting the injection part in the intubation process; the injection part 33 of the device and the laryngoscope are designed into a whole, so that the device is not easy to replace, the nozzle is easy to block and liquid medicine is easy to remain. Therefore, although the above patent devices have the functions of a visual laryngoscope and laryngeal anesthesia primarily, the device has the defects of complex operation, unstable anesthesia effect, easy blockage of a spraying system, easy pollution, high possibility of cross infection of patients and the like, and is difficult to achieve ideal effect in clinical practice.
Chinese patent documents: CN203389193U, publication date: 2014-01-15, with patent names: a surface anesthesia device special for an anesthetic laryngoscope.
