Description
Technical Field
The utility model relates to a medical apparatus, in particular to an airway mucosa surface anesthesia device capable of passing through a working channel of a fiber bronchoscope, which is used for assisting in airway examination or treatment under a bronchoscope awake state.
Background
The tracheal intubation in a waking state under the assistance of a fiber bronchoscope is an important method for solving the problem of the tracheal intubation of patients with difficult airways and gastric satiety, and the method requires the patients to keep awake and can be matched with doctors to operate. At present, the tracheal intubation is carried out after the surface anesthesia is punctured by atomizing and inhaling the surface anesthesia or the cricoterminous membranous, so that uncomfortable reactions such as choking cough, nausea and vomiting, suffocating breath and the like are frequently caused to patients, and huge pains and psychological fear are brought to the patients, so that the patients are not easy to cooperate, the time is too long, the surface anesthesia dosage is too large, the anesthesia effect is not definite and the like. So that the awake trachea cannula is greatly hindered under the assistance of the fiber bronchoscope, and the treatment time is musied.
The utility model patent with publication number of CN212914109U discloses a disposable shapable airway anesthesia spray tube, which adopts a hose to be sleeved into a shapable metal tube core to try to adapt to the change of an airway during intubation, the front end of the hose is closed, the side wall is provided with an opening, the tube core is pulled out when the tube core drives the hose to be inserted into an airway target point, the hose is left in the trachea, and then anesthetic liquid is injected from the rear end of the hose by an injector to be conveyed to the target point for anesthesia.
In the method, a hose is inserted into an airway, and anesthesia operation cannot be performed when the hose reaches a target point, because the tube core cannot enter without drawing out the gunpowder, the irritation to the airway mucosa is great, and the problems of choking, nausea, vomiting, breath holding and the like of a patient are unavoidable. Secondly, the tube core used in the method is made of materials such as shapable metal wires, one-time bending adaptation cannot be guaranteed for the complicated bending trend of the air passage, and the manual bending shaping method which is repeated for a plurality of times can be effective, so that the repeated air inlet and outlet of the air passage can aggravate the stimulation to a patient and cause the problems of resisting the matching of the patient and the like. Also, this method cannot directly look at the internal condition of the airway, and the intubation and the shaping are only based on the experience of doctors, so that great uncertainty exists. Thus, there is a need for improvements in this approach that incorporate existing fiberoptic bronchoscopy techniques.
Disclosure of Invention
Therefore, the utility model provides the airway mucosa surface anesthesia device capable of passing through the working channel of the fiber bronchoscope, the device does not need tube core shaping and repeated intubation, can directly look at the internal condition of the airway, realizes accurate positioning of an anesthesia area, has definite anesthesia effect and good effect, reduces pain of a patient and improves the coordination degree of the patient with little stimulation, and overcomes the defects in the prior art.
The airway mucosa surface anesthesia device capable of passing through the working channel of the fiber bronchoscope is provided with a needle tube, a hose and a surface anesthesia spray head, and is characterized in that the surface anesthesia spray head is of an elliptic sphere structure, one end of the surface anesthesia spray head is connected with the hose, a spray hole is formed in the elliptic sphere, the other end of the hose is connected with the needle tube so as to convey the gunny liquid to the surface anesthesia spray head for spraying, and the hose is made of polyurethane materials.
The surface hemp spray head and the hose are made of the same material into a whole.
The elliptic sphere of the surface hemp spray head is in a shape of an olive bar, the thickness of the elliptic sphere is less than or equal to 3mm, the long axis of the surface hemp spray head is overlapped with the pipeline center line of a hose, the outer diameter of the hose is less than or equal to 2mm, and the length of the hose is 70-85mm.
The needle tube and the hose can be connected in an interference fit manner or in a pipe joint manner.
The spraying holes of the surface anesthesia spray head are fine holes with the diameter smaller than 0.5mm and are uniformly distributed on the surface of the ellipsoid so as to release the gunpowder in a mist form to the periphery of the airway mucosa.
The utility model is used as follows:
after the fiber bronchoscope is inserted into the airway, one end of the surface anesthesia spray head is inserted into the working channel of the hand-held device to directly reach the front end of the bronchoscope, the surface anesthesia is carried out on the airway mucosa of the target area under the condition of looking at the front end directly on the display screen, the bronchoscope is further inserted when the patient needs to go deep into the airway, at the moment, the patient cannot feel pain under the action of the anesthetic, the patient can gradually push the surface anesthesia gradually, the pain of the whole intubation process is greatly reduced, the stimulation is slight, and various examinations and treatments are carried out by the patient under the condition that the patient is awake. After the operation is completed, the operation is withdrawn outside the body together with the fiberoptic bronchoscope.
The utility model has the characteristics of simple structure and convenient use, and the ellipsoidal surface anesthesia spray head of the hose head is designed with spray pores on the spherical surface, so that the anesthetic liquid can be ensured to be atomized after being sprayed out, and better absorption of the anesthetic is facilitated; simultaneously, the liquid medicine can be sprayed forwards and peripherally at the same time, so that the surface anesthesia liquid medicine is uniformly contacted with the mucous membrane tissues of the area to be anesthetized. Through the working channel of the fiber bronchoscope, the utility model reaches the front section of the bronchoscope, reaches the part to be anesthetized under the guidance of the working channel, can achieve accurate positioning under the direct vision of the lens, and can efficiently spray the anesthetic to the region to be anesthetized. The anesthesia is performed while the lens is advanced, and the difficult problem that the precise surface anesthesia is difficult for the awake tracheal intubation under the assistance of the prior fiber bronchoscope is solved. Meanwhile, the problem of anesthesia of the conventional plastic tube core intubation is avoided.
