Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multifunctional endoscopic diagnosis and treatment laryngeal mask. Background Technique

[0002] The laryngeal mask is an effective means for establishing a safe airway during general anesthesia surgery. When performing airway endoscopic diagnosis and treatment on patients, intravenous anesthesia is often required to assist in sedation and analgesia. The laryngeal mask has become the most important airway device except for tracheal catheters and is widely used in airway management of patients during general anesthesia surgery, treatment of emergency airways, and intubation of difficult airways at home and abroad.

[0003] The existing patent document with the publication number CN217526027U provides a through-type laryngeal mask with an auxiliary endoscopic diagnosis and treatment function. The endoscopic channel of this utility model is a through-type channel, which can guide the endoscope into the patient's esophagus. The axis of the through-type channel is a smooth curve, and the smooth curve is located in the longitudinal plane, and the longitudinal plane is parallel to the symmetry plane of the mask body. Compared with the prior art, the through-type laryngeal mask of this utility model can facilitate the insertion of the endoscope into the patient's stomach and avoid the endoscope from being stuck.

[0004] However, when the existing endoscopic diagnosis and treatment laryngeal mask is in use, it is not easy to avoid the situation that gastric juice and secretions generated during endoscopic diagnosis and treatment enter the inside of the ventilation tube. Since a large amount of gastric juice and secretions will be generated during endoscopic diagnosis and treatment, once the liquid enters the inside of the ventilation tube, it is very easy to cause the ventilation tube to be blocked, which directly affects the safety of endoscopic diagnosis and treatment operations. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 - Figure 4 , the present invention provides a technical solution: a multifunctional endoscopic laryngeal mask, including a main body mechanism 1 and a protection mechanism 2. The protection mechanism 2 is located behind the main body mechanism 1. The main body mechanism 1 includes a laryngeal mask body 101 and a first ventilation channel 102. The first ventilation channel 102 is fixedly arranged inside the laryngeal mask body 101.

[0026] The main body mechanism 1 further includes a fixing sleeve 103, a second ventilation channel 104, a protection valve 105 and an elastic rubber strip 106. The fixing sleeve 103 is fixedly installed at the rear end of the laryngeal mask body 101. The second ventilation channel 104 is fixedly arranged at the front end of the fixing sleeve 103. The second ventilation channel 104 is connected to the first ventilation channel 102 in a through manner. The protection valve 105 is movably installed inside the second ventilation channel 104. The elastic rubber strip 106 is fixedly installed inside the second ventilation channel 104. The rear end of the elastic rubber strip 106 is fixedly connected to the protection valve 105. When using the laryngeal mask body 101 for endoscopic diagnosis and treatment operations, medical staff send the laryngeal mask body 101 through the oral cavity to the throat part of the human body, so that the laryngeal mask body 101 contacts the human larynx. During the diagnosis and treatment process, the ventilator transports gas through the trachea 202 to the second ventilation channel 104 and the first ventilation channel 102. During the transportation of the gas, the airflow inside the second ventilation channel 104 squeezes the protection valve 105, causing the elastic rubber strip 106 to be squeezed, thereby driving the protection valve 105 to rotate to a certain extent, enabling the gas to enter the first ventilation channel 102. When there is liquid entering the second ventilation channel 104 through the first ventilation channel 102, the reverse pressure squeezes the protection valve 105. Supported by the elastic rubber strip 106, the protection valve 105 is fully closed to prevent liquid from entering the trachea 202.

[0027] The protection mechanism 2 includes a connecting pipe 201 and a ventilation pipe 202. The connecting pipe 201 is fixedly installed at the rear end of the fixed sleeve 103. The ventilation pipe 202 is fixedly installed at the upper end of the connecting pipe 201. The ventilation pipe 202 is connected to the second ventilation channel 104 in a penetrating manner. The protection mechanism 2 further includes a first endoscope channel 203 and a second endoscope channel 204. The first endoscope channel 203 is fixedly arranged inside the laryngeal mask body 101. The second endoscope channel 204 is fixedly arranged in the middle of the front end of the fixed sleeve 103. The second endoscope channel 204 is connected to the first endoscope channel 203 in a penetrating manner. The protection mechanism 2 further includes a first drainage channel 205 and a second drainage channel 206. The first drainage channel 205 is fixedly arranged at the lower end inside the laryngeal mask body 101. The second drainage channel 206 is fixedly arranged at the front end of the fixed sleeve 103. The second drainage channel 206 is connected to the first drainage channel 205 in a penetrating manner. The protection mechanism 2 further includes a first drainage pipe 207, a protective sleeve 208, and a flow-blocking valve 209. The first drainage pipe 207 is fixedly installed at the lower end of the connecting pipe 201. The first drainage pipe 207 is connected to the second drainage channel 206 in a penetrating manner. The protective sleeve 208 is fixedly installed at the rear end of the first drainage pipe 207. The flow-blocking valve 209 is movably installed inside the protective sleeve 208. The protection mechanism 2 further includes a compression spring 210 and a second drainage pipe 211. The compression spring 210 is fixedly installed inside the protective sleeve 208. The front end of the compression spring 210 is fixedly connected to the flow-blocking valve 209. The second drainage pipe 211 is fixedly installed at the rear end of the protective sleeve 208. Medical staff connect the ventilation pipe 202 to a ventilator, connect the second drainage pipe 211 to a collection device, then insert an endoscope through the connecting pipe 201 into the second endoscope channel 204 inside the fixed sleeve 103, extend it into the first endoscope channel 203 through the second endoscope channel 204, and extend it out from the first endoscope channel 203 for diagnosis and treatment operations. The gastric juice generated during the diagnosis and treatment process enters the second drainage channel 206 through the first drainage channel 205, then enters the protective sleeve 208 through the first drainage pipe 207. The pressure generated during the liquid transportation process squeezes the flow-blocking valve 209, so that the compression spring 210 is compressed, driving the two flow-blocking valves 209 to separate, enabling the liquid to enter the second drainage pipe 211 and be discharged. When the liquid inside the second drainage pipe 211 flows back into the protective sleeve 208, due to the special-shaped setting of the protective sleeve 208, the reverse pressure makes the flow-blocking valve 209 fit tightly with the protective sleeve 208, which can avoid the situation of gastric juice reflux.

[0028] Working principle: When using the laryngeal mask body 101 for endoscopic diagnosis and treatment operations, medical staff send the laryngeal mask body 101 through the oral cavity to the pharyngeal part of the human body, making the laryngeal mask body 101 contact with the human larynx. Then, connect the ventilation tube 202 to the ventilator and connect the second drainage tube 211 to the collection device. Then, insert the endoscope through the connecting tube 201 into the second endoscope channel 204 inside the fixing sleeve 103, extend it into the first endoscope channel 203 through the second endoscope channel 204, and extend out from the first endoscope channel 203 for diagnosis and treatment operations. During the diagnosis and treatment process, the ventilator transports gas through the ventilation tube 202 into the second ventilation channel 104 and the first ventilation channel 102. During the gas transportation process, the airflow inside the second ventilation channel 104 squeezes the protective valve 105, causing the elastic rubber strip 106 to be squeezed, thereby driving the protective valve 105 to rotate to a certain extent, allowing gas to enter the first ventilation channel 102. When liquid enters the second ventilation channel 104 through the first ventilation channel 102, the reverse pressure squeezes the protective valve 105. Supported by the elastic rubber strip 106, the protective valve 105 is fully closed to prevent liquid from entering the ventilation tube 202. The gastric juice generated during the diagnosis and treatment process enters the second drainage channel 206 through the first drainage channel 205, and then enters the protective sleeve 208 through the first drainage tube 207. The pressure generated during the liquid transportation process squeezes the flow-blocking valve 209, causing the compression spring 210 to be compressed, driving the two groups of flow-blocking valves 209 to separate, allowing the liquid to enter the second drainage tube 211 and be discharged. When the liquid inside the second drainage tube 211 flows back into the protective sleeve 208, due to the special-shaped setting of the protective sleeve 208, the reverse pressure causes the flow-blocking valve 209 to fully fit with the protective sleeve 208, which can prevent the occurrence of gastric juice reflux.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present invention shall not depart from the essence and scope of the technical solution of the present invention.
