Description

Technical Field

[0001] The utility model relates to the technical field of medical nutrition tubes, in particular to a magnetically controlled navigation jejunal nutrition tube. Background Art

[0002] In the treatment of critically ill patients, the use of jejunal feeding tubes is a common clinical medical product, which is mainly used to provide necessary nutritional support for patients who cannot take nutrition orally. The existing feeding tubes usually rely on the experience and skills of medical staff to place the feeding tubes, which can easily lead to inaccurate placement of the feeding tubes; and in the process of medical staff applying external force to insert the feeding tubes, the patient's discomfort is more serious, which is likely to cause other complications; such as the CORTRAK gastrointestinal nutrition navigation tube, the guide wire tip of the nutrition navigation tube is equipped with an electromagnetic transmitter, which can emit safe electromagnetic positioning information, thereby achieving three-dimensional precise positioning; although this design improves the placement accuracy of the nutrition navigation tube, the nutrition navigation tube is still placed by medical staff applying external force when inserted into the patient's body; this method is difficult to operate and the patient feels strong discomfort. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a magnetically controlled navigation jejunal nutrition tube, which solves the problem that the installation method of the prior nutrition tube easily causes strong discomfort to the patient.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A magnetically controlled navigation jejunal nutrition tube comprises a nutrition tube, one end of which is an inlet end for nutrients, and the other end of which is an outlet end for nutrients; a navigation magnetic block is provided at the outlet end, and the navigation magnetic block is connected to the inlet end through a guide wire, and the guide wire is accommodated in the nutrition tube; a navigation magnetic field device drives the nutrition tube to move in the patient's body through the magnetic force between the navigation magnetic block and the nutrition tube.

[0006] In this solution, the navigation magnetic field device can generate a directional magnetic field, which drives the navigation magnetic block to move, thereby driving the feeding tube into the patient's body; when the feeding tube is installed in this way, the feeding tube is actively extended into the patient's body under the driving action of the navigation magnetic block, and there is no need for medical staff to apply external force to passively insert it into the patient's body, which can reduce the patient's discomfort; and, inserting the feeding tube by magnetic drive can also reduce the difficulty of placing the feeding tube.

[0007] Furthermore, the entrance end of the nutrition tube is provided with a nutrient inlet and a magnetic inlet, the inner cavities of the nutrient inlet and the magnetic inlet are connected, and the guide wire is connected to the magnetic inlet; the nutrients are input into the nutrition tube from the nutrient inlet; and the navigation magnet is placed into the nutrition tube from the magnetic inlet.

[0008] In this solution, the nutrient inlet for inputting nutrients and the magnetic block inlet for placing the navigation magnetic block are designed separately; after the nutrition tube is inserted into the patient's body, the input of nutrients and the operation of the navigation magnetic block do not affect each other, which is convenient to use.

[0009] Furthermore, one end of the guide wire close to the magnetic block inlet is connected with a positioning block, a stop platform is provided in the magnetic block inlet, and the positioning block is fixed on the stop platform.

[0010] In this solution, a stopper is designed to fix the positioning block to prevent the navigation magnet and the guide wire from falling into the feeding tube during treatment.

[0011] Furthermore, a rubber ring is arranged inside the nutrient inlet, and the inner ring of the rubber ring is arranged to be inclined toward the direction in which the nutrients enter.

[0012] In this solution, the rubber ring disposed obliquely has a backflow prevention effect, which can prevent the nutrients from flowing back out from the nutrient inlet after being input into the nutrient tube.

[0013] Furthermore, the discharge end of the nutrition tube is designed with a round head with a smooth transition, and a nutrient outlet is provided at the end of the round head design, and the nutrients in the nutrition tube flow into the patient's body from the nutrient outlet.

[0014] In this solution, the round head design of the feeding tube allows for flexible advancement, low resistance, and a high rate of passing through the pylorus, which can minimize frictional damage to the digestive tract during the intubation process.

[0015] Furthermore, the navigation magnetic block has a bullet head structure, the outer diameter of which is larger than the opening diameter of the nutrient outlet; the navigation magnetic block is accommodated inside the nutrient outlet.

[0016] In this solution, the navigation magnet with a bullet-shaped design can autonomously slide to the nutrient outlet position of the nutrition tube and drive the nutrition tube to move when driving the nutrition tube to move, thereby avoiding the navigation magnet driving the nutrition tube to move at other positions of the nutrition tube during movement, thereby causing the nutrition tube to not move according to the designed route.

[0017] Furthermore, an electromagnetic transmitter is provided at the end of the navigation magnetic block, and the electromagnetic transmitter is connected to the navigation magnetic field device.

[0018] In this solution, the electromagnetic transmitter can emit electromagnetic positioning information and send it to the navigation magnetic field device, which can monitor the position of the nutrition tube in real time and achieve precise positioning.

[0019] Furthermore, the nutrient inlet and the magnetic block inlet are both provided with sealing covers.

[0020] The beneficial effects of the utility model are:

[0021] The navigation magnetic field device in the magnetically controlled navigation jejunal nutrition tube provided by the utility model drives the movement of the navigation magnetic block through the magnetic force, and the movement of the navigation magnetic block drives the nutrition tube into the patient's body; compared with the existing installation method in which medical staff apply external force to insert the nutrition tube into the patient's body, the contact pressure between the nutrition tube and the inner wall of the digestive tract can be reduced, thereby reducing the patient's discomfort.
