Description

Technical Field

[0001] This utility model relates to an auxiliary device for electronic gastroscopy and colonoscopy. More specifically, this utility model relates to an anesthesia mask for electronic gastroscopy and colonoscopy. Background Technology

[0002] Electronic gastroscopy and colonoscopy, including electronic gastroscopes and electronic colonoscopes, are instruments that penetrate deep into organs such as the esophagus, stomach, and intestines for examination. They are commonly used clinically to diagnose digestive tract diseases. To reduce patient discomfort during the examination, general anesthesia is required. However, under general anesthesia, the depth and frequency of breathing are affected by the anesthetic drugs. Obese patients are more prone to tongue retraction, which can easily lead to respiratory depression or even hypoxia. Currently, most gastroscopy and colonoscopy procedures under general anesthesia monitor this condition by tracking the patient's blood oxygen saturation during the procedure. However, since a drop in blood oxygen saturation usually occurs several minutes after respiratory arrest, it is difficult to detect respiratory abnormalities in time and take appropriate assisted ventilation measures, increasing the risk of hypoxia, which can even be life-threatening for elderly patients or those with multiple comorbidities. An existing patent (CN 215504999U) discloses a novel multifunctional oxygen supply mask with a carbon dioxide monitoring connector to monitor parameters such as the concentration and waveform of the patient's exhaled carbon dioxide. However, the carbon dioxide monitoring connector is located on the outer surface of the mask body, which does not allow for the provision of instrument channels. This makes it impossible to perform gastroscopy and colonoscopy under general anesthesia. Furthermore, clinical findings indicate that the manufacturing process is quite complex, the sampling point for end-tidal carbon dioxide is far from the patient's mouth and nose, and the accuracy of monitoring requires a high degree of mask sealing, which is not conducive to the rapid and timely detection and response to abnormal respiratory conditions in patients. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] Another objective of this invention is to provide an anesthesia mask for electronic gastrointestinal endoscopy, which can monitor end-tidal carbon dioxide in real time during the examination, accurately monitor the patient's respiratory status, detect respiratory depression in general anesthesia patients in real time, and effectively prevent hypoxemia in general anesthesia patients.

[0005] To achieve these objectives and other advantages according to this invention, an anesthesia mask for electronic gastroscopy and colonoscopy is provided, comprising a mask body with an oxygen channel and an instrument channel. The mask body also includes a carbon dioxide monitoring channel, comprising a through-hole in the mask body and a sampling extension tube passing through the through-hole, the sampling extension tube extending along the inner wall of the mask body to near the patient's nose. The oxygen channel is used to connect to an oxygen supply device to provide sufficient oxygen to the patient during the procedure. The instrument channel is, for example, located in the patient's oral cavity area to facilitate the insertion of instruments such as electronic gastroscopes or electronic enteroscopes. The instrument channel may include components such as soft silicone rings to improve patient comfort. This invention positions the end of the sampling extension tube for collecting end-tidal carbon dioxide near the patient's nose, closer to the nostrils, reducing the requirement for mask airtightness, resulting in more precise sampling and more accurate monitoring results. This allows medical personnel to observe the patient's breathing based on the monitoring results and take appropriate response measures in a timely manner, greatly improving medical safety.

[0006] Preferably, the end of the sampling extension tube is provided with at least one sampling tube. The sampling port of the sampling tube is close to the patient's nostrils, which can promptly acquire the patient's exhaled gas and connect to the monitoring instrument for analysis via the sampling extension tube. Of course, multiple sampling ports can also be provided on the sampling extension tube, for example, the sampling extension tube can be arranged around the patient's nostrils on the inner wall of the mask, thereby allowing for the collection of end-tidal carbon dioxide data from multiple points and improving the accuracy of monitoring the patient's respiratory status.

[0007] Preferably, the mask includes, from top to bottom, a nasal side portion, a middle portion, and a mandibular portion; the instrument channel is located in the middle portion; the oxygen channel is located in the mandibular portion; and no opening is provided in the nasal side portion. The middle portion is positioned to face the patient's oral cavity to facilitate the insertion of examination instruments such as electronic gastroscopes or electronic enteroscopes. The oxygen channel is located, for example, in the patient's mandibular portion to facilitate oxygen supply under general anesthesia. The absence of openings in the nasal side portion prevents interference from external gases or leakage of the supplied oxygen, allowing the sampling tube to accurately collect parameters such as carbon dioxide concentration, partial pressure, and waveform at the end of the patient's respiration.

[0008] Preferably, the through-hole is located between the mandibular region and the middle region, and the sampling tube passes through the through-hole and extends along the inner wall of the mask to the nasal side. The through-hole is formed on the mask wall, for example, by removing a portion of the mask, and has no components protruding from the outer surface of the mask, thus not occupying any surgical space and not affecting the surgeon's operation.

[0009] Preferably, the sampling extension tube extends into three sampling tubes at its end. These three sampling tubes are, for example, located near the patient's two nostrils, and multiple sampling ports may be provided on the sampling tubes to increase sampling data and improve the accuracy of monitoring results.

[0010] Preferably, the sampling tube and the sampling extension tube are integrally formed. The sampling tube is formed, for example, by the sampling extension tube extending in three directions. The sampling extension tube is, for example, made of medical-grade non-toxic transparent soft polyvinyl chloride plastic or high-performance polyolefin thermoplastic elastomer material.

[0011] Preferably, the first end of the sampling extension tube is connected to an end-tidal carbon dioxide (PETCO2) monitoring device. PETCO2 monitoring can reflect the patient's spontaneous breathing, including respiratory rate, tidal volume, and respiratory waveform. Therefore, abnormal breathing can be detected promptly during gastroscopy and colonoscopy under general anesthesia, facilitating rapid response measures.

[0012] Preferably, the inner wall of the mask is provided with multiple elastic clips at equal intervals for fixing the sampling extension tube. The elastic clips can detachably fix the sampling extension tube, thereby allowing the sampling position to be adjusted at any time according to the patient's body shape. Alternatively, the sampling extension tube can be fixedly attached to the inner wall of the mask using adhesive.

[0013] Preferably, the instrument channel includes an instrument hole formed in the middle portion and a soft rubber ring fixed in the instrument hole.

[0014] Preferably, an air cushion is provided around the perimeter of the cover. The air cushion is, for example, a transparent inflatable air cushion.

[0015] This invention offers at least the following advantages: The anesthesia mask for electronic gastroscopy and colonoscopy described herein has a simple structure, reasonable design, and is easy and convenient to operate. The through-hole is located in the chin area of ​​the mask, through which the sampling extension tube passes, without interfering with the operator's work. The sampling extension tube bypasses the instrument channel, thus not affecting the operator's field of vision; the position and number of the sampling tubes can also be adjusted at any time, expanding the sampling range and enabling more precise monitoring of the patient's respiratory status; thus ensuring the successful completion of the surgery.

[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0020] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0021] like Figure 1 , Figure 2 As shown, this utility model provides an anesthesia mask for electronic gastroscopy and colonoscopy, including a mask body 100. The mask body 100 has an oxygen channel 200 and an instrument channel 300. The mask body 100 also includes a carbon dioxide monitoring channel 400, which includes a through hole 401 in the mask body 100 and a sampling extension tube 402 passing through the through hole 401. The sampling extension tube 402 extends along the inner wall of the mask body 100 to the vicinity of the patient's nose. The oxygen channel 200 is, for example, a threaded conduit extending from the outer surface of the mask body 100 for connecting to an oxygen supply device. The instrument channel 300 is, for example, a large through hole passing through the middle portion of the mask body 100, for the passage of examination instruments such as electronic gastroscopy and colonoscopy instruments. This invention provides a through-hole 401 between the oxygen channel 200 and the instrument channel 300. An extension tube 402 for collecting end-tidal carbon dioxide from the patient passes through the through-hole 401, bypasses the instrument channel 300, and is then positioned at or near the patient's nostril. This allows for real-time and accurate monitoring of the patient's respiratory status, timely detection of intraoperative abnormalities, and ensures prompt response and treatment.

[0022] In one embodiment, such as Figure 2 As shown, at least one sampling tube 403 is provided at the end of the sampling extension tube 402. There are three sampling tubes 403, which are respectively arranged near the patient's nostrils. By increasing the number of sampling points, the accuracy of end-tidal carbon dioxide monitoring is improved, and the response efficiency is increased.

[0023] In one embodiment, such as Figure 1 and Figure 2As shown, the mask 100 includes, from top to bottom, a nasal side portion 101, a middle portion 102, and a chin portion 103; the instrument channel 300 is disposed in the middle portion 102; the oxygen channel 200 is disposed in the chin portion 103; the nasal side portion 101 has no openings. The mask 100 can be divided into the nasal side portion 101, the middle portion 102, and the chin portion 103 corresponding to the patient's mouth and nose. The chin portion 103 faces the lower edge of the patient's mouth and is used to connect an oxygen supply device to provide timely oxygen for the patient's breathing. The middle portion 102, for example, faces the patient's mouth, facilitating the insertion of examination instruments.

[0024] In one embodiment, such as Figure 1 As shown, the through hole 401 is located between the mandibular portion 103 and the intermediate portion 102. The sampling tube 403 passes through the through hole 401 and extends along the inner wall of the cover 100 to the nasal side portion 101. The nasal side portion 101 does not have any holes; thus, it can be ensured that the sampling tube 403 can collect the patient's end-tidal carbon dioxide status in a timely and accurate manner, ensuring the accuracy of the monitoring results.

[0025] In one embodiment, such as Figure 2 As shown, three sampling tubes 403 extend from the end of the sampling extension tube 402.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, the sampling tube 403 and the sampling extension tube 402 are integrally formed. Both can be made of medical-grade non-toxic transparent soft polyvinyl chloride plastic, reducing processing difficulty and cost.

[0027] In one embodiment, such as Figure 1 and Figure 2 As shown, the sampling extension tube 403 is connected to an end-tidal carbon dioxide (PETCO2) monitoring device (not shown in the figure) at its corresponding end. The device can be a mainstream carbon dioxide monitor, a bypass carbon dioxide monitor, or a comprehensive multi-parameter monitor with an end-tidal carbon dioxide (PETCO2) monitoring module. These devices can acquire the patient's end-tidal carbon dioxide (PetCO2) in a timely manner and monitor the patient's intraoperative respiratory status accurately in real time by displaying parameters such as the waveform and pressure of the end-tidal carbon dioxide.

[0028] In one embodiment, such as Figure 2As shown, multiple elastic clips 404 for fixing the sampling extension tube 402 are evenly spaced on the inner wall of the cover 100. Each elastic clip 404 can be a pair of clips with appropriate elasticity formed on the inner wall of the cover 100; the sampling extension tube 402 can be pressed into the elastic clip 404 by applying a certain external force. Alternatively, the elastic clip 404 can be an adhesive, allowing the sampling extension tube 402 to be detachably attached to the inner wall of the cover 100. The elastic clip 404 facilitates fine-tuning of the position of the sampling tube 403 by medical personnel according to the patient's facial condition and nostril position, thereby improving sampling accuracy. The elastic clip 404 can also be a type of adhesive to fix the sampling extension tube 402 to the inner wall of the cover 100.

[0029] In one embodiment, such as Figure 1 As shown, the instrument channel 300 includes an instrument hole formed in the middle portion and a soft rubber ring 301 fixed inside the instrument hole. The instrument channel 300 may also be provided with a cover 302. The soft rubber ring 301 serves to protect the patient's oral cavity. The cover 302 is used to increase the oxygen supply airtightness and improve oxygen supply to the patient when not performing procedures or in emergencies.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, an air cushion 104 is provided around the periphery of the cover 100. The air cushion 104 is, for example, a transparent, inflatable air cushion used to protect the patient's face.

[0031] In use, medical personnel place the inner wall of the cover 100 over the patient's face, aligning the instrument channel 300 with the patient's mouth; the oxygen channel 200 is positioned at the patient's chin, and the nasal side 101 covers the patient's nasal cavity. Medical personnel adjust the position of the sampling tube 403 through the through-hole 401, positioning it around the patient's nostrils. The end-tidal carbon dioxide (PETCO2) monitoring device can then be turned on or off as needed according to the progress of the surgery.

[0032] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
