Description

Throat anesthesia medicine sprayer for gastroscope

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a throat anesthesia medicine sprayer for gastroscope.

Background

Medical personnel typically require a relatively long gastroscopic lumen from the patient's mouth into the stomach with a diameter of about two centimeters, with minor differences in the size. The epiglottis of the patient's throat is inevitably touched during insertion of the gastroscope lumen, which results in nausea and vomiting. At the moment, medical staff usually deal with the method that a patient drinks a bottle of liquid medicine, the liquid medicine can quickly anaesthetize the epiglottis of the throat within ten minutes after entering the throat, and the feeling of nausea and vomiting can not be excessively generated when a gastroscope enters the throat. But at the same time creates a problem: since the liquid medicine is taken by self, the operation is not normal, most of the anesthetic effect is easy to exist only on the tongue and the head, and the parts mainly generating nausea are still sensitive, so that the discomfort feeling in the examination cannot be relieved. Therefore, a novel throat anesthetic sprayer for gastroscopy is needed.

For example, chinese patent publication No. CN207734457U discloses a throat anesthetic sprayer for gastroscopy, which includes a medicine bottle, an upper cover, a sealing cover, and a medicine spraying nozzle, wherein the upper cover is fixed on the upper end of the sealing cover, the medicine spraying nozzle is fixed with a screw cap with a hollow middle part, a medicine inlet cavity is arranged on the inner side of the upper cover, a pump is fixed on the inner side of the upper cover on the upper end surface of the sealing cover, a lower conduit is fixed on the lower end of the pump, an upper end pipe is fixed on the upper end of the pump, a battery seat is fixed on the outer side of the circumference of the upper cover, a power switch is fixed on the right side of the upper cover, a check valve is fixed on the outer side of the upper cover on the sealing cover, an air inlet seat is further connected on the right side of the medicine inlet cavity, a pressurizing rod capable of sliding left and right is further arranged in the air inlet seat, and medicine spraying ports are further distributed on the outer side of the circumference of the lower end position of the medicine spraying nozzle. The utility model discloses a beneficial effect does: the throat anesthesia medicine sprayer for the gastroscope has fewer parts and accessories, and the whole anesthesia process can be completed only by pressing the power switch and pressing the pressure increasing rod inwards for a while after the medicine liquid is filled; the replacement is convenient, the spray nozzle can be quickly replaced by rotating, and the anesthesia efficiency is improved; meanwhile, the medicine spraying nozzle can enter an epiglottis part on the inner side of a throat, so that the medicine liquid is sprayed along the circumference to completely cover a sensitive part, and the condition that nausea and vomiting are caused when a gastroscope is carried out can be effectively reduced. However, the utility model still has the following technical disadvantages: although the medicine spraying nozzle of the utility model is arranged in a curved shape, a structure close to ninety degrees is formed between the oral cavity and the throat part of a human body; when the medicine spraying nozzle extends into the throat part of a patient, the parts such as the epiglottis of the throat of the patient can still be inevitably touched, and then the medicine spraying nozzle can generate the symptoms of nausea and vomiting due to touching the epiglottis of the throat of the patient when anesthesia is carried out, so that the utility model which is used for avoiding generating the symptoms of nausea and vomiting can cause a great deal of uncomfortable symptoms of the patient by itself. Therefore, improvement is necessary to overcome the disadvantages of the prior art.

To facilitate understanding of the working principle of the present embodiment, the working process of the present embodiment is briefly described as follows: first, an anesthetic is poured into the vial body 203, and the seal cap 202 is screwed onto the vial body 203. When the anesthetic from the medicine bottle body 203 needs to be sprayed to the deep part of the throat cavity of the patient through the nozzle 6, the angle between the adapter assembly 5 and the connecting piece 3 can be adjusted through the rotating handle 10 to adapt to the position of the oral cavity of the patient, particularly the throat. For example, the stem 10 may be adjusted to adjust the angle between the adapter assembly 5 and the connector 3 to ninety degrees. Secondly, the adapter assembly 5 and the nozzle 6 are together extended into the deep throat of the oral cavity of the patient, the liquid outlet hose 1 is pushed to the oral cavity of the patient along the connecting piece 3 by the sleeve 4, so that the nozzle 6 can move forward to the deep position of the oral cavity, throat and cavity of the oral cavity of the patient along the adapter assembly to push the liquid outlet hose to the position where the anesthetic needs to be sprayed. By the configuration mode, the liquid outlet hose 1 which is directly close to ninety degrees is close to the deep part of the throat cavity of the patient to touch the inner wall of the throat cavity of the patient, so that the discomfort reaction of nausea and the like of the patient can be avoided. Then, the power switch 16 is pressed to supply power through the power source 15 and start to extract the liquid medicine in the medicine bottle body 203. When the pump 14 is started, the liquid medicine can be discharged from the upper end pipe directly into the medicine inlet cavity 11. At this time, the liquid medicine cannot be sprayed out of the medicine inlet cavity 11, the pressure rod 19 needs to be drawn out to enable air to enter the medicine inlet cavity 11 along the air inlet seat 18, and then the pressure rod 19 is compressed to increase the pressure in the medicine inlet cavity 11; when the pressure is increased, the liquid medicine is forced to enter the liquid outlet hose 1 and is finally sprayed out through the nozzle 6. For example, the nozzle 6 may be sprayed with an anesthetic to cover the entire epiglottis region to completely paralyze it. During the whole anesthesia process, the medical staff can clearly observe the volume of the liquid medicine in the medicine bottle body 203 through the observation window 20.

It should be noted that the above-mentioned embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure, which are also within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
