Technical Field

The invention relates to the field of medical instruments, in particular to a nasointestinal tube with a bionic structure.

Background

In critically ill patients, early enteral nutrition intervention is required, which requires manual placement of catheters to establish tube feeding pathways. When a critically ill patient establishes an artificial airway for mechanical ventilation, high reflux and high aspiration risks exist, so that a catheter is usually kept in the jejunum for the critically ill patient clinically so as to reduce the incidence rate of feeding-related complications.

The head section of the pork tapeworm is pear-shaped, 4 sucker folds and 1 protruding top protrusion are arranged beside the periphery of the head, 28-48 small hooks or guide lines are arranged on the top protrusion in a radial mode, and the neck of the head is similar to the tapeworm and is an annular knot; the hookworm cloaca is designed, the intestinal tract wriggling and stretching are realized, the outlet elasticity is changed, the blockage is not easy to occur, and if the blockage occurs, the synechia is extracted to remove the blockage.

At present, the problems of the nose intestine tube mainly include that a great deal of time is consumed for entering the intestine, and the pain of a patient is increased; the pH value of the intestinal tract can be used as an important index for judging the digestion degree of a patient, and a portable and simple detection mode is lacked; in addition, the nasointestinal tube is easy to slip in the intestinal tract for a long time.

Disclosure of Invention

The invention solves the problems that the existing nose intestinal canal is difficult to enter the intestinal tract, is difficult to fix and does not have a PH detection function, and provides the nose intestinal canal with a bionic structure.

The invention provides a nasointestinal tube with a bionic structure, which is characterized by comprising:

a nasointestinal tube, comprising: the device comprises a connector, a pipe body, outlets, a pull ring part, a dredging part and a gravity detection part, wherein one end of the pipe body is connected with the connector and the pull ring part, the other end of the pipe body is connected with the gravity detection part, two outlets are arranged at two corresponding sides of the pipe body close to the gravity detection part, the dredging part is arranged on the pipe body close to one of the outlets, and the pull ring part is connected with the dredging part.

Furthermore, the gravity detection part comprises a gravity hammer, short fibrous features are distributed on the surface of the front end of the gravity hammer, and the free end part of the fibrous features is of a hook-shaped structure.

Furthermore, the pull ring part comprises a pull ring, a return spring and a traction filament, the pull ring is sequentially connected with the return spring and the traction filament, and the traction filament is fixedly connected with the dredging part.

Furthermore, the dredging part is a U-shaped notch feature, and the traction filament is connected with the U-shaped notch feature.

Furthermore, at least one PH detection sensor is distributed on the gravity hammer.

A nasointestinal tube of a biomimetic structure, comprising: the device comprises a pipe body, a Ruhr joint, a pull ring, a return spring, a traction filament, a U-shaped notch feature, an outlet, a gravity hammer, a fibrous feature, a PH sensor and a display, wherein the Ruhr joint is connected with one end of the pipe body, the pull ring, the return spring and the traction filament are sequentially arranged on a side branch at the same end, the traction filament is connected with the U-shaped notch feature through the inside of the pipe body, the U-shaped notch feature is arranged at a position close to the outlet, the outlet is arranged at a position close to the gravity hammer, at least one outlet is arranged, the gravity hammer is arranged at the other end of the pipe body, short fibrous features are uniformly distributed on the outer surface of the gravity hammer, the free end part of the fibrous feature is of a bent hook structure, at least one PH sensor is arranged on the gravity hammer, the display is positioned at one end of the tube body connected with the Ruhr joint, and signals detected by the PH sensor are processed and then displayed on the display.

The action principle is as follows: the scheme of the invention simulates pork tapeworm to carry out bionic design, the gravity hammer at one end of the tube body mainly simulates the head of the tapeworm, short fibrous characteristics are arranged on the gravity hammer, the free end part of the gravity hammer is in a hook-shaped design, the gravity hammer can be more easily adsorbed on a small intestine mucous membrane, a fibrous structure is opened and adsorbed on the small intestine mucous membrane after the nasointestinal tube is installed in place, the nasointestinal tube is prevented from being displaced, the constantly opened state can be maintained, but the difficulty in entering the small intestine from the nasointestinal tube can be possibly caused, and the gravity hammer is designed to better enter the intestinal tract; in addition, U type incision characteristic with pull the filament and link to each other and then with reset spring, the pull ring links to each other, U type incision characteristic is in the closure state under normal condition, the laminating is closing, when taking place to block up, through the pulling pull ring, U type crop characteristic is intraductal to move, loosen the pull ring, under reset spring's effect, U type incision characteristic resets, repeated several can be dredged deposited protein or food, can prolong the live time of nose intestines pipe, reduce the number of times of changing, alleviate patient's misery and burden.

The invention has the beneficial effects that: through the bionic design, the nose intestine tube can easily enter the small intestine, can be fixed with the mucous membrane of the small intestine after reaching a preset position, can be dredged when being blocked, prolongs the service life of the nose intestine tube, reduces the replacement times, and relieves the pain and burden of a patient.
