Description

Improvement of nasogastric endoscopic lens structure

The present invention provides an endoscopic lens used in a nasogastric tube, and in particular, an improved structure of a nasogastric endoscopic lens in which a guide is designed in front of the endoscopic lens to effectively prevent fluid from blocking the shooting range of the lens.

According to the so-called nasogastric tube, it is inserted into the stomach through the nasal cavity and pours liquid food into the stomach. It is mainly used for patients who are unable to eat by mouth or who need a large amount of nutritional supplements to provide easy-to-digest and absorb liquid food for patients to obtain. Proper calories and nutrition.

However, during the process of inserting the nasogastric tube into the stomach, it must enter the human body through the nasal cavity, and there are two channels, one is the esophagus and the other is the airway. Therefore, during the insertion process, experience and feel are required for insertion. If the insertion is into the esophagus, it means the position is correct. If the insertion is into the airway, it means the position is wrong and needs to be re-inserted. Such repeated insertion actions are simply called blind insertion. There are several problems with blind insertion. One is that repeated insertion and removal are often The second reason is that the insertion position is wrong, including intubation in the airway or esophagus penetration, causing intubation in the pleural cavity. Therefore, in order to solve the above problems, a lens method has also been developed to identify whether the insertion is incorrect. , such as the Republic of China Certificate No. M637407 "System for assisting placement of nasogastric tube/nasointestinal tube", including a tube and an image capture device. One end of the tube has a bend, and the image capture device is installed on The front end of the bending part; and a display unit, which is connected with the signal of the endoscope device. The display unit is connected with the signal of the endoscope device, and is used to receive and display the image of the internal channels of the human body or the image of the internal organs captured by the endoscope device. The information is sent to the display unit, and the tube can be placed into the target channel according to the image information of the internal channel of the human body or the internal organ image.

However, when the above-mentioned system for assisting the placement of nasogastric tubes/nasointestinal tubes is used, the following problems and deficiencies do exist and need to be improved:

Although the route of the nasogastric tube can be viewed in real time through the image capture device (camera lens) in order to know the current insertion position of the nasogastric tube, the image capture device cannot be used to insert the nasogastric tube before inserting it. Lubricating fluid will be applied to the endoscopic device so that the endoscopic device can travel more smoothly after entering the nasogastric tube. However, during the process of traveling, due to the small space inside the nasogastric tube and the dry wall, the endoscopic device will The endoscope device may still get stuck during insertion, so the endoscope device must be moved back a certain distance before moving forward. However, with this movement, fluid will accumulate in front of the lens, causing the lens shooting range to be blocked by other parts of the lens. Obstructed, it is impossible to see whether the current route of the nasogastric tube is correct.

Therefore, how to solve the above conventional problems and deficiencies is the direction that the inventor of the present invention and related manufacturers engaged in this industry are eager to research and improve.

Therefore, in view of the above shortcomings, the applicant of the present invention collected relevant information, evaluated and considered many parties, and used his many years of experience in this industry to design such an endoscopic lens through continuous trial production and modification. A guide is designed in the front to effectively prevent fluid from blocking the shooting range of the lens. The inventor has patented an improvement in the structure of the nasogastric endoscopic lens.

The main purpose of the present invention is: through the guide member provided on the camera body, the lubricating fluid attached to the shooting range of the camera body can be effectively moved in the opposite direction to the forward direction of the endoscope, so that the images captured by the camera body can be moved The picture is clearer.

The main structure of the present invention that can achieve the above object includes a nasogastric tube. The nasogastric tube has a channel, and both ends of the nasogastric tube have an opening connected to the channel, and an endoscopic tube is passed through the opening. The endoscope enters the channel. It is worth mentioning that one end of the endoscope is provided with a camera component. The camera component includes a camera body, a signal transmission element that is information-connected to the camera body, and A guide member is provided on the camera body and allows the endoscope to move the lubricating fluid in the opposite direction to the forward direction during the advancement process, and the guide member is located in the range captured by the camera body. Therefore, when the nasogastric tube enters the human nasal cavity, the user can record through the camera body to see whether the current route of the nasogastric tube has deviated. When entering the nasogastric tube, lubricating fluid is used to make the endoscope more smoothly when passing through the nasogastric tube. Therefore, when the conventional image capture device travels through the nasogastric tube, it The front lens of the image capture device is a flat lens. The lubricating fluid will accumulate on the front lens of the image capture device, affecting the shooting clarity of the image capture device. It may even be completely blocked and unable to shoot. Therefore, In this case, the lubricating fluid can be taken away in the opposite direction through the guide member, so that it will not accumulate in the area captured by the camera body.

Through the above technology, the existing problem of the system used to assist in the placement of nasogastric tubes/nasointestinal tubes can be solved. Although the path of the nasogastric tube can be viewed in real time through the image capture device (camera) to know the current insertion position of the nasogastric tube, the image capture device will apply a lubricating fluid on the endoscope device before inserting the nasogastric tube, so that the endoscope device can move more smoothly after entering the nasogastric tube, but during the process of moving, the endoscope device will be placed in the nasogastric tube. In the process of inserting the nasogastric tube, the internal space of the nasogastric tube is small and the tube wall is relatively dry. Therefore, the endoscopic device may get stuck during insertion. Therefore, the endoscopic device must be moved back a certain distance before moving forward. However, due to this action, the fluid will accumulate in front of the lens, blocking the lens shooting range, and it is impossible to see whether the current route of the nasogastric tube is correct. This problem is solved, and the practical progress of the invention as mentioned above is achieved.

Therefore, the endoscope 2 must be moved back some distance before moving forward. However, as a result of this movement, fluid will accumulate in front of the camera body 211, making the shooting range of the camera body 211 more likely to be obscured by it (as shown in Figure 4A). However, there is no need to worry. Medical staff can use the endoscope again. 2 is inserted into the port 13 of the nasogastric tube. At this time, the lubricating fluid 3 originally accumulated in the front of the camera body 211 will be accumulated backward around the guide 213 due to the relationship between the guide 213 (the surrounding area is is the non-shooting range of the camera body 211), repeat the above action until the endoscope 2 travels to the appropriate position and stops insertion. Then the nasogastric tube 1 combined with the endoscope 2 can be inserted into the patient's nasal cavity. , during the insertion process, the light-emitting element 214 is turned on and emits light to perform the lighting action, and the captured image is wirelessly transmitted to the external terminal by the signal transmission element 212.
