Multifunctional mouth gag for gastrointestinal endoscopy under anesthesia state

Technical Field

The utility model relates to the field of intraoperative ventilation auxiliary devices, in particular to a multifunctional mouth gag for gastrointestinal endoscopy under an anesthesia state.

Background

The information disclosed in this background of the utility model is only for enhancement of understanding of the general background of the utility model and is not necessarily to be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

The painless gastrointestinal endoscopy adopts visual gastrointestinal endoscopy to enter the stomach or the intestinal tract, and the gastrointestinal tract mucous membrane change and pathological changes are observed through direct vision, thereby achieving the purpose of auxiliary diagnosis and treatment of gastrointestinal tract diseases. When intravenous anesthesia is used for painless gastrointestinal endoscopy, a patient often has tongue tenesmus, so that hypoxemia is caused, and potential cardiovascular and cerebrovascular accident risks are brought to the patient, especially to the elderly with hypertension, heart disease and diabetes. Therefore, keeping the respiratory tract of a patient subjected to painless gastrointestinal endoscopy constantly is a key factor for preventing and treating the occurrence of hypoxemia during the examination process.

At present, in the painless gastrointestinal endoscopy examination process, in order to prevent glossoptosis and hypoxemia, a mandible lifting method is often adopted to keep the respiratory tract smooth, but the mode not only increases the workload of an anesthesiologist, but also has unsatisfactory respiratory tract opening effect.

The ventilation part is fixedly connected to the right side wall of the cushion part and the ventilation part and the cushion part are on the same plane. The two connecting lugs are respectively connected to the left side wall of the cushion part and the right side wall of the ventilation part, and the binding parts are connected to the two connecting lugs. The rear wall surface of the alveolar pad part is provided with an annular alveolar pad, and a through hole in the annular alveolar pad is communicated with the gastrointestinal endoscope channel.

Furthermore, the outer wall of the alveolar pad is provided with an alveolus.

Further, the alveolus forms an annular alveolus around the outer wall of the alveolar pad, so that the mouth gag can be more stably fixed in the mouth by the matching of the teeth and the alveolus of the patient.

Furthermore, the rear wall surface of the ventilation part is connected with an arc-shaped duct which is bent downwards, the duct is communicated with the oxygen duct channel, and the duct is obliquely arranged against the bite-block part.

Further, the gastrointestinal passageway is sized larger than the oxygen passageway for access by a corresponding instrument.

Furthermore, the cushion part, the ventilation part and the connecting lug are integrally formed.

Further, the material of the cushion portion and the ventilation portion includes hard plastic or the like.

Further, the binding component is two binding belts which are respectively connected in two connecting holes on the connecting lug, and when in use, the whole mouth gag is fixed in the mouth of a patient through the two binding belts.

Furthermore, the two binding bands are connected in an adjustable and detachable mode through magic tapes or buckles.

Furthermore, the binding component is an elastic rope, and two ends of the elastic rope are respectively connected to the two connecting holes on the connecting lugs.

Compared with the prior art, the utility model has the following beneficial effects:

(1) the mouth gag of the utility model can be fixed in the oral cavity of a patient to ensure that the oral cavity keeps a good opening degree in the examination process, and overcomes the problems that the traditional method of lifting the lower jaw to keep the respiratory tract smooth not only increases the workload of an anaesthetist, but also has poor opening effect. Simultaneously, the entering of a gastrointestinal endoscope and an oxygen tube can be realized through the arrangement of the cushion part and the ventilation part, so that the examination is facilitated, meanwhile, the oxygen supply for a patient is facilitated, and the hypoxemia is prevented.

(2) The arc-shaped conduit bent downwards arranged on the multifunctional mouth gag can be used as a channel of an oxygen tube, and can enter the oral cavity of a patient and press the tongue to fix the tongue root in the using process, so that the tongue root can be effectively prevented from falling backwards, and hypoxemia caused by blocking the trachea can be prevented.
