Description

Technical Field

[0001] The utility model belongs to the field of gastric tube devices, and particularly relates to a gastric tube with an anti - aspiration structure. Background Art

[0002] A gastric tube is a medical device, usually a long and slender flexible tube. The current gastric tubes have some obvious drawbacks. Firstly, due to the lack of an anti - aspiration structure, gastric contents are prone to reflux into the esophagus and respiratory tract, which may cause patients to aspirate and trigger serious complications such as aspiration pneumonia. The main reason for this drawback is that the design of the gastric tube is relatively simple and cannot effectively prevent the backflow of contents when the gastric pressure changes. For this drawback, conventional countermeasures include controlling the infusion speed and volume, and maintaining a proper position for the patient after infusion. However, it is not always possible to accurately control the infusion speed and volume, and sometimes the effect is not good due to individual differences or changes in the patient's condition. Moreover, the method of maintaining the patient's position also has drawbacks because the patient may unconsciously change their position during the treatment process, and maintaining a single position for a long time also has a certain impact on the patient's comfort and recovery. In addition, these methods cannot fundamentally solve the problem of gastric content reflux, and there is still a relatively high risk of aspiration, which requires medical staff to closely observe and care at all times, increasing the difficulty and pressure of medical work. Therefore, a new structure is needed to solve the above - mentioned technical problems. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a gastric tube with an anti - aspiration structure to solve the problems raised in the above background art.

[0004] The utility model is realized through the following technical solutions: A gastric tube with an anti - aspiration structure includes: a face mask and a gastric tube assembly. An oxygen port is opened on the surface of the face mask, and a gastric tube assembly is installed on the surface of the face mask. The gastric tube assembly includes: a gastric tube body, a first trachea, a second trachea, a first airbag, a second airbag, a partition, a silica gel valve, and a pressure sensor. The first airbag and the second airbag are installed on the outer surface of the gastric tube body. The first trachea and the second trachea are symmetrically installed on the outer surface of the gastric tube body. The first trachea is connected to the first airbag, and the second trachea is connected to the second airbag. The interior of the gastric tube body is divided into a main cavity and a secondary cavity by a partition. A silica gel valve is installed in the main cavity, and a pressure sensor is installed in the secondary cavity. An inlet is provided at the upper end of the gastric tube body through the main cavity, and an outlet is provided at the lower end of the gastric tube body through the main cavity.

[0005] As a preferred embodiment, the face mask is mounted on the surface of the user. At the center position of the lower edge of the front side surface of the face mask, a gastric tube body is mounted. One end of the gastric tube body away from the face mask is disposed in the stomach. On the upper side edge of the outer surface of the gastric tube body, a trachea one and a trachea two are symmetrically mounted. The trachea one and the trachea two have the same structure. One ends of the trachea one and the trachea two away from the gastric tube body are connected to a gas supply device.

[0006] As a preferred embodiment, valves are mounted on the outer surfaces of the trachea one and the trachea two. An airbag one is mounted in the middle of the outer surface of the gastric tube body. An airbag two is mounted at the lower end of the outer surface of the gastric tube body. The airbag one and the airbag two have the same structure. When in use, the settings of the airbag one and the airbag two can more effectively block the gap between the esophagus and the gastric tube, greatly reducing the risk of gastric contents refluxing into the esophagus and the respiratory tract.

[0007] As a preferred embodiment, the trachea one and the trachea two are disposed inside the gastric tube body. The material of the gastric tube assembly is medical silica gel. The space of the main cavity inside the gastric tube body is larger than that of the auxiliary cavity. A plurality of silica gel valves are evenly mounted inside the main cavity. The silica gel valves are one-way valves.

[0008] As a preferred embodiment, a pressure sensor is mounted at the outlet of the lower end of the auxiliary cavity. The pressure sensor is connected to a monitoring device through a wire. The airbag two is disposed at the junction of the stomach and the esophagus. When in use, the partition divides the gastric tube body into a main cavity and an auxiliary cavity, so that the infusion channel (main cavity) of the nutrient solution or drug and the pressure monitoring channel (auxiliary cavity) are independent of each other and do not interfere with each other, which can ensure the stability of the infusion process and the accuracy of pressure monitoring.

[0009] As a preferred embodiment, the airbag two is disposed inside the esophagus.

[0010] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By providing a gastric tube assembly, the gastric tube assembly includes: a gastric tube body, a trachea one, a trachea two, an airbag one, an airbag two, a partition, a silica gel valve, and a pressure sensor. An airbag one and an airbag two are mounted on the outer surface of the gastric tube body. A trachea one and a trachea two are symmetrically mounted on the outer surface of the gastric tube body. The trachea one is connected to the airbag one, and the trachea two is connected to the airbag two. When in use, the settings of the airbag one and the airbag two can more effectively block the gap between the esophagus and the gastric tube, greatly reducing the risk of gastric contents refluxing into the esophagus and the respiratory tract.

[0011] By setting a partition plate, a main cavity and a secondary cavity are formed inside the gastric tube body by the partition plate. A silica gel valve is installed inside the main cavity, and a pressure sensor is installed inside the secondary cavity. An inlet is provided at the upper end of the gastric tube body through the main cavity, and an outlet is provided at the lower end of the gastric tube body through the main cavity. When in use, the partition plate divides the gastric tube body into a main cavity and a secondary cavity, so that the infusion channel (main cavity) of nutrient solution or medicine is independent of the pressure monitoring channel (secondary cavity) and does not interfere with each other, which can ensure the stability of the infusion process and the accuracy of pressure monitoring.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1 to 2, the present utility model provides a technical solution: a gastric tube with an anti-aspiration structure, including: a face mask 100 and a gastric tube assembly. An oxygen port 110 is provided on the surface of the face mask 100, and a gastric tube assembly is installed on the surface of the face mask 100. The gastric tube assembly includes: a gastric tube body 200, a trachea one 210, a trachea two, an airbag one 220, an airbag two 230, a partition 270, a silicone valve 251, and a pressure sensor 261. An airbag one 220 and an airbag two 230 are installed on the outer surface of the gastric tube body 200. A trachea one 210 and a trachea two are symmetrically installed on the outer surface of the gastric tube body 200. The trachea one 210 is connected to the airbag one 220, and the trachea two is connected to the airbag two 230. A main cavity 250 and a sub-cavity 260 are formed inside the gastric tube body 200 through the partition 270. A silicone valve 251 is installed inside the main cavity 250, and a pressure sensor 261 is installed inside the sub-cavity 260. An inlet is provided at the upper end of the gastric tube body 200 through the main cavity 250, and an outlet is provided at the lower end of the gastric tube body 200 through the main cavity 250.

[0019] Please refer to Figures 1 to 2 , as the first embodiment of the present utility model: The face mask 100 is installed on the surface of the user. The gastric tube body 200 is installed at the center of the lower edge of the front surface of the face mask 100 (a sealing switch is provided at the connection between the face mask 100 and the front surface of the gastric tube body 200). The end of the gastric tube body 200 away from the face mask 100 is arranged in the stomach. The trachea one 210 and the trachea two are symmetrically installed at the upper edge of the outer surface of the gastric tube body 200. The trachea one 210 and the trachea two have the same structure. The ends of the trachea one 210 and the trachea two away from the gastric tube body 200 are connected to a gas supply device;

[0020] Valves 211 are installed on the outer surfaces of the trachea one 210 and the trachea two. An airbag one 220 is installed in the middle of the outer surface of the gastric tube body 200. An airbag two 230 is installed at the lower end of the outer surface of the gastric tube body 200. The airbag one 220 and the airbag two 230 have the same structure;

[0021] When in use, the user first fixes the mask 100 on the user's face through an additional fixing structure, and then inserts the gastric tube assembly into the esophagus and stomach (the above entire operation needs to be carried out in a sterile environment, and the gastric tube assembly is made of medical materials and needs to be disinfected in advance). When inserting the lower end of the gastric tube body 200 into the stomach, at this time, the second airbag 230 on the outer surface of the lower end of the gastric tube body 200 is also inserted into the stomach through the gastric tube body 200. After the insertion is completed, the user can activate the second trachea to inflate the second airbag 230 through the air supply device. At this time, the user can pull the gastric tube body 200 to make the second airbag 230 clamped at the connection between the stomach and the esophagus (cardia). Then, the first trachea 210 can be activated again to inflate the first airbag 220 through the air supply device, so that the first airbag 220 clamps the esophagus, thereby preventing the user from inhaling the gastric tube assembly. Due to the settings of the first airbag 220 and the second airbag 230, the gap between the esophagus and the gastric tube can be blocked more effectively, greatly reducing the risk of gastric contents refluxing into the esophagus and respiratory tract.

[0022] Please refer to Figures 1 to 2 , as the second embodiment of the present utility model: the first trachea 210 and the second trachea are arranged inside the gastric tube body 200. The material of the gastric tube assembly is medical silica gel. The space of the main cavity 250 inside the gastric tube body 200 is larger than the space of the secondary cavity 260. A plurality of silica gel valves 251 are evenly installed inside the main cavity 250, and the silica gel valves 251 are one-way valves;

[0023] A pressure sensor 261 is installed at the outlet of the lower end of the secondary cavity 260. The pressure sensor 261 is connected to the monitoring device through a wire. The second airbag 230 is arranged at the junction of the stomach and the esophagus.

[0024] The second airbag 230 is arranged inside the esophagus;

[0025] When in use, after the user installs the gastric tube body 200 through the operation steps of the first embodiment, the user can open the sealing switch arranged at the connection between the mask 100 and the front surface of the gastric tube body 200 at this time, and then inject an object into the stomach through the main cavity 250. Since the silica gel valves 251 installed in the main cavity 250 can effectively prevent gastric contents from refluxing into the main cavity 250, this helps to reduce the risk of aspiration and ensure the safety of infusion. Moreover, the partition 270 divides the gastric tube body 200 into the main cavity 250 and the secondary cavity 260, so that the infusion channel (main cavity 250) of the nutrient solution or drug and the pressure monitoring channel (secondary cavity 260) are independent of each other and do not interfere with each other. This can ensure the stability of the infusion process and the accuracy of pressure monitoring. And the pressure sensor 261 in the secondary cavity 260 can sense the pressure change in the stomach in real time, and medical staff can adjust the treatment plan in time according to the pressure data, such as adjusting the infusion speed, taking body position change measures, etc.

[0026] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
