Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a nasointestinal tube with a bionic structure. Background Art

[0002] Early enteral nutrition intervention is required for critically ill patients, and early enteral nutrition intervention requires artificial placement of a catheter to establish a tube feeding route. When an artificial airway is established for mechanical ventilation in critically ill patients, there is often a high risk of reflux and aspiration. Therefore, in clinical practice, catheters are often placed in the jejunum for such patients to reduce the incidence of feeding-related complications.

[0003] The pork tapeworm head segment is pear-shaped, with four suction cup folds and a protruding apex around the head. There are two circles of small hooks or guide lines on the apex, totaling 28 to 48, arranged radially. The neck is similar to that of the tapeworm, with an annular nodule. The hookworm's cloaca is designed to stretch the intestine due to peristalsis, and the elastic size of the outlet changes, so it is not easy to get blocked. If blockage occurs, the copulation spines are removed to clear the blockage.

[0004] At present, the main problems with nasogastric tubes are that they take a lot of time to enter the intestines, which increases the patient's pain; the intestinal pH value can be used as an important indicator to judge the patient's digestion degree, but there is a lack of portable and simple detection methods; in addition, nasogastric tubes are in the intestines for a long time and are prone to slipping. Summary of the invention

[0005] The present invention solves the problems that the existing nasointestinal tube is difficult to enter the intestine, difficult to fix and has no pH detection function, and provides a nasointestinal tube with a bionic structure.

[0006] The present invention provides a nasointestinal tube with a bionic structure, characterized by comprising:

[0007] A nasointestinal tube, characterized in that it comprises: a joint, a tube body, an outlet, a pull ring portion, a dredging portion, and a gravity detection portion, one end of the tube body is connected to the joint and the pull ring portion, the other end of the tube body is connected to the gravity detection portion, there are two outlets on corresponding sides of the tube body near the gravity detection portion, a dredging portion is provided on the tube body near one of the outlets, and the pull ring portion is connected to the dredging portion.

[0008] Furthermore, the gravity detection part includes a gravity hammer, and a front end surface of the gravity hammer is distributed with short fibrous features, and a free end of the fibrous feature is a hook-shaped structure.

[0009] Furthermore, the pull ring portion includes a pull ring, a reset spring, and a traction filament. The pull ring is connected to the reset spring and the traction filament in sequence, and the traction filament is fixedly connected to the dredging portion.

[0010] Furthermore, the dredging portion has a U-shaped incision feature, and the traction filament is connected to the U-shaped incision feature.

[0011] Furthermore, at least one pH detection sensor is distributed on the gravity hammer.

[0012] A nasointestinal tube with a bionic structure, characterized in that it includes: a tube body, a Luer connector, a pull ring, a reset spring, a traction filament, a U-shaped incision feature, an outlet, a gravity hammer, a fibrous feature, a pH sensor, and a display. The Luer connector is connected to one end of the tube body, and the pull ring, the reset spring, and the traction filament are sequentially installed on the side branch at the same end. The traction filament passes through the inside of the tube body and is connected to the U-shaped incision feature. The U-shaped incision feature is arranged near the outlet, and the outlet is located near the gravity hammer. There is at least one outlet, and the gravity hammer is installed at the other end of the tube body. Short fibrous features are evenly distributed on the outer surface of the gravity hammer, and the free end of the fibrous feature is a hook-shaped structure. There is at least one pH sensor and it is located on the gravity hammer. The display is located at one end of the tube body connected to the Luer connector, and the signal detected by the pH sensor is displayed on the display after processing.

[0013] Working principle: The scheme of the present invention simulates the pork tapeworm to make a bionic design, mainly including a gravity hammer at one end of the tube body to imitate the tapeworm head, on which short fibrous features are arranged and the free end is designed in a hook shape, which can be more easily adsorbed on the small intestinal mucosa. After the nasointestinal tube is installed in place, the fibrous structure opens and adsorbs on the small intestinal mucosa to prevent the nasointestinal tube from shifting. Of course, it can also be maintained in an open state, but it may cause some difficulty for the nasointestinal tube to enter the small intestine. The gravity hammer is designed to better enter the intestine; in addition, the U-shaped incision feature is connected to the traction filament and then to the reset spring and the pull ring. Under normal conditions, the U-shaped incision feature is in a closed state and fits on the closure. When blockage occurs, by pulling the pull ring, the U-shaped cut head feature moves into the tube, and the pull ring is released. Under the action of the reset spring, the U-shaped incision feature is reset. Repeating several times can clear the deposited protein or food, which can extend the service life of the nasointestinal tube, reduce the number of replacements, and reduce the pain and burden of patients.

[0014] The beneficial effects of the present invention are: through bionic design, the nasointestinal tube of the present invention can easily enter the small intestine, and can be fixed to the small intestinal mucosa after reaching the predetermined position. When blockage occurs, it can be unblocked, thereby extending the service life of the nasointestinal tube, reducing the number of replacements, and alleviating the patient's pain and burden. In addition, through the PH detection device, the patient's digestive condition can be judged by the PH value, thereby achieving accurate intestinal nutrition. BRIEF DESCRIPTION OF THE DRAWINGS
