Gravity-type nasoenteric tube with color-developing function for flushing

technical field

The utility model relates to the technical field of medical instruments, in particular to a gravity-type nasoenteric tube with a color-developing ribbon flushing function.

Background technique

Nutritional support is an important part of the treatment of critically ill patients, and its approach is an important part of nutritional support. Enteral nutrition is recommended as the preferred form of support for critically ill patients. The latest research shows that early routine administration of enteral does not affect the mortality and complications of infection in critically ill patients. During the implementation of enteral nutrition, the choice of feeding tube is also one of the important factors affecting nutrient intake. Feeding tubes can be either nasal or oral gastric tubes and small intestinal tubes. For patients with impaired gastric motility, enteral nutrition with a small bowel feeding tube can reduce the risk factors for aspiration.

Blind insertion of a small bowel tube at the bedside is similar to that of gastric tube insertion. The smooth tip of the small intestinal tube should be inserted into the pharynx from the patient's widest nostril, and then, if the patient can swallow, allow the small intestinal tube to enter the stomach after swallowing. The patient is then turned to the right so that the tip of the catheter can be pushed through the pylorus and into the duodenum by peristalsis of the stomach. Knowing the position of the catheter tip is important when intubating a patient who is unconscious or has an impaired cough reflex. The gas injection method may mislead the operator due to other factors. The easiest way to identify catheter insertion into the gastrointestinal tract is to withdraw the gastrointestinal contents. If the gastrointestinal contents cannot be withdrawn, imaging of the catheter is the most reliable method.

According to the above, the current method for judging whether the nasointestinal tube is in the intestine is to roughly estimate the exposed length, and then irradiate the patient to determine the position. This method cannot immediately determine the position of the catheter, and there are certain problems. In the process of implementing enteral nutrition, in order to prevent tube blockage, the guidelines recommend implementing pulsed irrigation every 4 hours to prevent tube blockage. When the current nasoenteric tube is flushed, the nutrient solution must be disconnected and then connected to the feeding device for flushing. The operation process is cumbersome, and it is easy to contaminate the nutrient solution, which increases the probability of enteral nutrition complications for patients. In view of the above shortcomings, there are It is necessary to design a gravity-type nasoenteric tube with a color-developing function of flushing.

Compared with the prior art, the gravity-type nasointestinal tube with a color-developing belt flushing function can improve the insertion effect of the naso-enteric tube due to the gravity effect of the water bladder when the naso-intestinal tube penetrates into the patient's body, and the medical staff can also connect the naso-enteric tube. The head is connected to the external water injection mechanism, and then the adjustment and control of the water volume inside the water bladder is achieved by suction. At the same time, because the normal pH range of human gastric juice is 0-4, and the normal range of small intestinal juice pH is 6-8, that is, medical staff can pass Pull the syringe, that is, through the action of suction, the liquid in the patient's body flows from the detection tube into the connection cover through the detection hole, that is, it is in contact with the color-developing chip. When the color chip is used, the litmus test paper turns red in the presence of acid (PH<7). If the liquid is small intestinal fluid, the litmus test paper turns blue in the presence of alkali (PH>7). At this time, the above operations are used to facilitate the The medical staff can quickly know the in-depth position of the nasointestinal tube, which effectively avoids the traditional need to use X-rays to determine the position, which brings great inconvenience to the operation. First, through the gravity effect of the water bladder, the insertion effect of the nasoenteric tube can be improved, and the slippage of the nasoenteric tube can be effectively avoided. Secondly, through the cooperation effect of the built-in color measuring mechanism, it can greatly facilitate the medical staff to determine the in-depth position of the nasoenteric tube, effectively It avoids the traditional need to use X-ray films to determine the position, which brings great inconvenience to the operation, expands the convenience of clinical operations, and is conducive to popularization and application. Convenience, the baffle is to seal the water bladder.
