Background technique

General anesthesia without intubation refers to the application of general anesthesia drugs to achieve the effect of sedation and analgesia, while preserving spontaneous breathing and protective reflexes. In clinical anesthesia, operations or operations under general anesthesia without intubation, including gastrointestinal endoscopy, artificial abortion, tumor radiofrequency ablation, non-invasive examinations that do not require patient cooperation (CT, MRI, ophthalmological examinations, etc.), short invasive Examination or operation (hysteroscopy, needle biopsy, etc.) and invasive surgery that requires patient cooperation (chronic pain treatment, etc.).

However, general anesthesia without intubation can cause adverse events such as respiratory depression, so it is necessary to judge whether the patient's breathing is depressed during the operation. The traditional way of judging breathing conditions is to rely on observing lip color, chest rise and oxygen saturation, etc., but in most cases, the changes in lip color and chest rise are not obvious, and the obtained results are inaccurate, and there is a certain lag in oxygen saturation detection sex. Misjudgment and untimely judgment will affect the judgment of the patient's vital signs, and even put the patient's life in danger.

Detailed ways

The structures involved in the present invention or the technical terms used are further described below. These descriptions are only used as examples to illustrate how the method of the present utility model is realized, and cannot constitute any limitation to the present utility model.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described. In the description of the present utility model, it should be understood that the orientations or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left" and "right" are based on the The orientation or positional relationship is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the referred position or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as the scope of the utility model. limit. In addition, the terms "first", "second", etc. are used for descriptive purposes only, and should not be construed as indicating or implying relative importance.

In this utility model, unless otherwise specified and limited, "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integration; It may be a direct connection, or an indirect connection through an intermediary, and may be an internal communication between two elements or an interaction relationship between two elements, unless otherwise clearly defined. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

As shown in Figures 1-4, an end-tidal carbon dioxide monitoring device under non-intubated general anesthesia includes a mouth pad 1 and a gas outflow channel 2. The mouth pad 1 includes a panel 11, a bite cylinder 12, and a tongue depressor 13. The panel 11 It communicates with the bite cylinder 12 to form a through hole 14. The gas outflow channel 2 is arranged along the wall of the through hole and is located at the mouth corner of the hole wall. The front end 21 of the gas outflow channel extends into the oral cavity and is flush with the front end of the bite cylinder 12. End Tidal Capnography 3.

The reason why the gas outflow channel 2 is arranged along the wall of the through hole and at the corner of the mouth is because if the gas outflow channel is placed outside the mouth pad, it will cause discomfort in the patient's mouth and affect the patient's sense of experience. The gas outflow channel 2 is located at the corner of the mouth and does not hinder the insertion of tools such as colonoscopes and gastroscopes. The front end 21 of the gas outflow channel is flush with the front end of the bite cylinder 12, which can prevent the gas outflow channel 2 from going deep into the oral cavity and obstructing tool operation.

As a specific embodiment, the gas outflow channel 2 is a conduit, and the conduit is pasted on the wall of the hole with high-strength, waterproof, non-toxic glue, see FIG. 2 . Alternatively, the gas outflow channel is an air hole, and the air hole and the mouth pad are integrally formed.

As a specific embodiment, when the gas outflow channel 2 is a conduit, the outer diameter is 7-9 mm, preferably 8 mm; the inner diameter is 6-8 mm, preferably 7 mm. When the gas outflow channel 2 is a pore, the inner diameter of the pore is 6-8 mm, preferably 7 mm. The outer diameter of the gas outflow channel 2 should not be too thick, which will affect the operation of the tool in the oral cavity, and should not be too thin, which will affect the monitoring results.

As a specific embodiment, when the gas outflow channel 2 is a conduit, it is made of soft polyvinyl chloride. Soft, non-toxic, prevents stabbing oral skin and mucous membranes, and is harmless to human health.

As a specific implementation, the rear end 22 of the gas outflow channel is provided with an interface 221 , and the interface 221 is connected to the collection catheter 31 of the end-tidal carbon dioxide monitor, and the structure of the interface 221 is adapted to the collection catheter 31 .

End-tidal carbon dioxide can not only monitor the pulmonary ventilation status, but also reflect the circulatory function and pulmonary blood flow, and is one of the sensitive and rapid indicators. The utility model fixes the gas outflow channel on the mouth pad, so that the front end of the gas outflow channel extends into the patient's oral cavity, and the rear end is connected to the collection catheter of the end-tidal carbon dioxide monitor, which can monitor the respiratory wave pattern and respiratory frequency of patients under non-intubated general anesthesia in real time. In order to judge whether the patient's breathing is inhibited, it can also monitor the patient's pulmonary ventilation status, circulatory function, pulmonary blood flow and other conditions. The device obtains data quickly and accurately, thereby providing accurate judgment basis for the operator, and making a judgment quickly.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
