Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for colonoscopy, and in particular to an automated airway management device for painless gastrointestinal endoscopy. Background Technology

[0002] An endoscope is a medical instrument used for examination and treatment. It is used to examine lesions of the esophagus, stomach, and duodenum. An endoscopy requires anesthesia and involves inserting a thin, flexible tube into the stomach, allowing doctors to directly observe lesions of the esophagus, stomach, and duodenum.

[0003] In the prior art, a gastrointestinal endoscope with a self-cleaning function, disclosed in patent application CN210990179U, includes a base. A support is fixedly mounted on the top of the base, and a fixing block is fixedly mounted on the support. The fixing block has a fixing hole, and a sliding rod is slidably mounted on the fixing block. One end of the sliding rod extends into the fixing hole and is fixedly mounted with a clamping block. A spring is slidably sleeved on the sliding rod, with one end fixedly connected to the clamping block and the other end fixedly connected to the inner wall of the fixing hole. An annular block is fixedly mounted on the support, and an annular cavity is formed on the annular block. Multiple nozzles are fixedly mounted on the bottom of the annular block, and all nozzles communicate with the annular cavity. After use, it automatically cleans itself, reducing the workload of medical personnel and improving diagnostic and treatment efficiency.

[0004] In the above-mentioned technical solutions, the patient lies flat during gastroscopy and the device is inserted into the stomach through the mouth and esophagus. During this process, the position of the gastroscope needs to be moved and adjusted. During the movement of the gastroscope, secretions from the mouth and esophagus will adhere to the outer wall of the gastroscope tube, which can easily carry the secretions into the airway opening, thus easily causing airway infection. To address this, we propose an automated airway management device for painless gastroscopy and colonoscopy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an automated airway management device for painless gastrointestinal endoscopy, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automated airway management device for painless gastroscopy and colonoscopy, comprising a cannula, wherein a gastroscope slot is provided inside the cannula, a gastroscope insertion end is provided inside the gastroscope slot, an oxygen inlet structure is provided on the outer wall of the cannula, the oxygen inlet structure includes an air outlet provided on the outer wall of the cannula, and an isolation structure is installed on the upper and lower sides of the air outlet on the outer wall of the cannula.

[0007] As a further technical solution of this utility model, an oxygen channel is provided inside the cannula, and the lower end of the oxygen channel is connected to the gas outlet.

[0008] As a further technical solution of this utility model, the upper end of the oxygen channel is connected to a connector, and the outer wall of the connector is provided with an external thread, and the connector is connected to the ventilator through the external thread.

[0009] As a further technical solution of this utility model, the isolation structure includes two rubber rings, both of which are fixedly sleeved on the outer wall of the insertion tube. The two rubber rings are arranged on the upper and lower sides of the air outlet, and the interior of the rubber rings is provided with cavities.

[0010] As a further technical solution of this utility model, the isolation structure also includes an air intake channel disposed inside the insertion tube, and the air intake channel is connected to the cavity through a connecting pipe.

[0011] As a further technical solution of this utility model, the upper end of the air intake channel is connected to an air intake pipe, and a piston is provided inside the air intake pipe.

[0012] As a further technical solution of this utility model, a threaded sleeve is fixedly installed at the end of the air intake pipe, and a threaded rod is connected to the inside of the threaded sleeve. One end of the threaded rod is connected to the piston, and a handle is installed at the other end of the threaded rod.

[0013] This invention provides an automated airway management device for painless gastroscopy and colonoscopy, which has the following advantages compared with the prior art:

[0014] By inserting a tube to separate the endoscope insertion point, direct contact between the endoscope insertion point and the patient's airway opening is avoided during movement. This prevents secretions from being introduced into the airway opening when adjusting the position of the endoscope insertion point, thus improving the safety of equipment use and preventing airway infection in patients.

[0015] By automatically controlling the patient's airway breathing status through a ventilator, the ventilator drives air into the connector and oxygen channel, allowing air to directly enter the patient's airway opening through the oxygen channel's outlet, thereby effectively managing the patient's breathing status.

[0016] When the cavities of the two rubber rings are inflated, the outer walls of the rubber rings adhere to the upper and lower sides of the patient's airway opening. This isolates the secretions in the patient's esophagus and prevents gastric secretions from flowing back into the airway opening during the movement of the endoscope insertion.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This invention provides an automated airway management device for painless gastroscopy and colonoscopy, including a cannula 1, a gastroscope slot 2 inside the cannula 1, a gastroscope insertion end 3 inside the gastroscope slot 2, and an oxygen inlet structure 4 on the outer wall of the cannula 1. The oxygen inlet structure 4 includes an air outlet 41 on the outer wall of the cannula 1, and isolation structures 5 are installed on the upper and lower sides of the air outlet 41 on the outer wall of the cannula 1. In use, the cannula 1 is first inserted into the patient's mouth, with the air outlet 41 located at the patient's airway opening. Then, the gastroscope insertion end 3 is inserted into the patient's esophagus through the gastroscope slot 2 of the cannula 1. This isolates the gastroscope insertion end 3 from the patient's airway opening during movement of the cannula 1, preventing secretions from being introduced into the airway opening when adjusting the position of the gastroscope insertion end 3, thus improving the safety of the device and preventing airway infection in the patient.

[0025] like Figure 2 and Figure 4As shown, in this embodiment, the cannula 1 is provided with an oxygen channel 42. The lower end of the oxygen channel 42 is connected to the air outlet 41, and the upper end of the oxygen channel 42 is connected to a connector 43. The outer wall of the connector 43 is provided with an external thread 44. The connector 43 is connected to the ventilator through the external thread 44. In use, the external thread 44 of the connector 43 is threadedly connected to the ventilator, which facilitates the assembly work of medical staff. In use, the ventilator automatically controls the patient's airway breathing status and uses the ventilator to drive air into the connector 43 and the oxygen channel 42, so that the air enters the patient's airway opening directly through the air outlet 41 of the oxygen channel 42, thereby effectively managing the patient's breathing status.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the isolation structure 5 includes two rubber rings 51, both of which are fixedly fitted onto the outer wall of the insertion tube 1. The two rubber rings 51 are disposed on the upper and lower sides of the air outlet 41. A cavity 52 is provided inside the rubber rings 51. The isolation structure 5 also includes an air inlet channel 54 disposed inside the insertion tube 1. The air inlet channel 54 is connected to the cavity 52 through a connecting pipe 53. An air inlet pipe 55 is connected to the upper end of the air inlet channel 54. A piston 56 is disposed inside the air inlet pipe 55. A threaded sleeve 57 is fixedly installed at the end of the air inlet pipe 55. A threaded rod 58 is threadedly connected inside the threaded sleeve 57. One end of the threaded rod 58 is connected to the piston 56, and a handle 59 is installed at the other end of the threaded rod 58. Two rubber rings 51 are set on the upper and lower sides of the air outlet 41. When the cavity 52 of the two rubber rings 51 is inflated, the outer wall of the rubber rings 51 is attached to the upper and lower sides of the patient's airway opening. This can isolate the secretions in the patient's esophagus and prevent the gastric secretions from flowing back into the airway opening during the detection and movement of the gastroscope insertion end 3. When in use, the handle 59 drives the threaded rod 58 to rotate, which allows the threaded rod 58 to cooperate with the threaded sleeve 57 to extend and retract. Then, the end of the threaded rod 58 drives the piston 56 to move, so that the piston 56 drives the air inside the air inlet pipe 55 to enter the cavity 52 of the rubber ring 51 through the air inlet channel 54 and the connecting pipe 53, thereby driving the rubber ring 51 to inflate.

[0027] The working principle of this utility model is as follows:

[0028] When using the device, first insert the cannula 1 into the patient's mouth, with the air outlet 41 located at the patient's airway opening. Then, insert the end end 3 of the endoscope into the patient's esophagus through the endoscope slot 2 of the cannula 1. This separates the end end 3 of the endoscope from the endoscope by the cannula 1, preventing the end end 3 from directly contacting the patient's airway opening during movement. This also prevents secretions from being introduced into the airway opening when adjusting the position of the end end 3, thus improving the safety of the device and preventing airway infection in the patient.

[0029] When in use, the ventilator automatically controls the patient's breathing status through the airway. The ventilator drives air into the connector 43 and the oxygen channel 42, so that the air enters the patient's airway opening directly through the outlet 41 of the oxygen channel 42, thereby effectively managing the patient's breathing status.

[0030] When the cavities 52 of the two rubber rings 51 are inflated, the outer walls of the rubber rings 51 adhere to the upper and lower sides of the patient's airway opening. This can isolate the secretions in the patient's esophagus and prevent gastric secretions from flowing back into the airway opening during the detection and movement of the endoscope insertion point 3.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
