Description

Technical Field

[0001] The invention relates to the technical field of nasojejunal tubes, in particular to a nasojejunal tube with three cavities and ultrasound imaging. Background Art

[0002] During the three-chamber ultrasound imaging treatment, a corresponding nasojejunal tube needs to be adapted for auxiliary physical therapy, so the quality of the nasojejunal tube determines the overall treatment quality; For example, a three-cavity ultrasonic imaging nasojejunal tube with publication number CN215840533U comprises a catheter body, a gastrointestinal decompression cavity, a jejunal feeding tube cavity and a gastric tube cavity. The bottom of the jejunal feeding tube cavity is connected to the top of the catheter body. The gastrointestinal decompression cavity and the gastric tube cavity are inserted from the top of the catheter body and extend downward. A gastrointestinal decompression cavity opening and a gastric tube cavity opening are provided in the middle of the catheter body. The bottoms of the gastrointestinal decompression cavity and the gastric tube cavity are connected to the gastrointestinal decompression cavity opening and the gastric tube cavity opening by the inner cavity of the catheter body, respectively. A serrated hollow structure is formed between the outer wall of the lower end of the catheter body and the inner cavity, which is conducive to ultrasonic observation of the image of the catheter, and the imaging is more obvious under ultrasound; the CT confirmation of the catheter position is eliminated, the work efficiency of medical staff is improved, and the medical expenses of patients are reduced; the operation is simple, safe and efficient; Another example is a nasojejunal tube with a publication number of CN2540954Y, which includes a silicone tube with a guide wire built in the silicone tube, a closed front end, a steel ball built in the front end of the silicone tube, and a hole opened on the front end wall of the silicone tube. It can reach the jejunum through the patient's nose, esophagus and stomach, and directly deliver ordinary liquid food to the jejunum. Since the cost of ordinary liquid food is much lower than the nutrient solution delivered intravenously, it can greatly reduce the cost of treatment, reduce the economic burden of patients, and reduce many complications caused by long-term total parenteral nutrition. It is particularly suitable for use as a device for delivering ordinary liquid food to patients with severe pancreatitis, gastroparesis, etc. who need to fast; For example, a nasojejunal tube with publication number CN213466067U comprises: a first tube body, wherein the proximal side of the first tube body is provided with an inlet and the distal side is provided with an opening, and the first tube body has a passage passing through the inlet and the opening; and a second tube body, wherein the proximal side of the second tube body is provided with an inlet for introducing or extracting liquid, the second tube body comprises a longitudinally extending main body and a sac portion at the distal side of the main body, the main body and the sac portion are configured to be fixedly sleeved on at least part of the outer circumference of the first tube body, a first chamber is provided in the main body for accommodating the introduced liquid, a second chamber is provided in the sac portion for accommodating the introduced liquid, and the second chamber is in fluid communication with the first chamber, and the sac portion is located proximal to the distal opening of the first tube body; Most of the above-mentioned existing technologies have improved their overall structure, but the existing three-chamber ultrasound-imaging nasojejunal tube cannot stably and adaptively perform positioning processing when it is docked inside the nasal cavity during operation, which causes the position of the tube to be easily affected by movement deviation when the user performs medical operations, thereby causing uncomfortable medical experience to the patient, and thus there are certain limitations in use. Summary of the invention

[0006] Furthermore, an air supply hose passes through the lower end of the built-in docking airbag, and the air supply hose extends along the interior of the preset base, and the end of the air supply hose is connected to the interior of the external docking airbag component. The inner wall of the external docking airbag component is docked with a built-in docking support plate and a magnet component, and the built-in docking support plate and the magnet component are arranged with the same magnetic poles facing each other.

[0007] Furthermore, when the nested docking pieces are under pressure, they drive the docking connectors to form a nested docking structure along the interior of the preset base, and the inwardly moved nested docking pieces simultaneously apply pressure to the contacting built-in docking airbags along the interior of the preset base.

[0008] Furthermore, the built-in docking airbag expands by supplying air through the air supply hose and the interior of the external docking airbag component, and the repulsive force between the built-in docking support sheet and the magnet component with the same magnetic poles inside the external docking airbag component stably supports its formation degree.

[0009] Furthermore, the disposable nasojejunal tube body is nested and docked with the lower end of the preset base through a nested docking piece to form a detachable structure, and reserved through holes are symmetrically opened at the upper end of the disposable nasojejunal tube body.

The replaceable disposable nasojejunal tube body can be quickly replaced or cleaned and disinfected later, avoiding the disadvantages of the traditional integrated structure. When the fluid is supplied inside the preset matrix, the nested docking piece at the inner end will be pressed to drive the docking connector to move along the inside of the preset matrix, and the inwardly moved nested docking piece will synchronously pressurize the contacted built-in docking airbag, and the built-in docking airbag will cooperate with the air supply hose to form air supply expansion work inside the external docking airbag part, and the corresponding position of the patient's nasal cavity can be self-positioned by the deformation-expanded external docking airbag part, so that the patient's nasal cavity can be self-positioned during the work process, and the patient can be quickly taken and placed when the work stops. Furthermore, the repulsive force between the built-in docking support sheet and the magnet part of the external docking airbag part with the same magnetic poles stably supports its formation degree, and stably and adaptively performs the basic position positioning processing of the overall device, avoiding the influence of the movement deviation of the placement position when the user performs medical operations, and bringing better medical experience to the patient; Furthermore, an auxiliary locking structure is provided, and the overall device can adaptively control the installation stability state of the disposable nasojejunal tube body through the auxiliary locking structure.

At this time, the limiting movable part will cooperate with the reserved through hole to form a self-locking nested structure with the upper end of the disposable nasojejunal tube body, that is, the self-locking processing is realized during the operation of the device. When it stops being used, the disposable nasojejunal tube body can be disassembled and replaced by simply unplugging and plugging, thereby improving the practicability of the device.
