Description

Supplementary needle tube formula liquid diet conversion extension fixture of stomach fistulization pipe

Technical Field

The utility model relates to a stomach fistulization pipe extension fixture, in particular to a needle tube formula liquid diet conversion extension fixture is assisted to stomach fistulization pipe belongs to medical technical field.

Background

The stomach fistulation tube is inserted into the stomach fistulation tube by means of abdominal skin puncture under the guidance of endoscope, and is a special tube feeding nutrition method. The stomach fistulation tube is placed on the premise that patients have oral ingestion disorder, but the gastrointestinal function of the patients is normal, and the patients need long-term tube feeding nutrition support for more than 4 weeks. After the stomach fistulization tube is left, the patient or family members can carry out long-term domestic enteral nutrition through the stomach fistulization tube, and the life quality of the patient is improved. According to different conditions of patients, three modes of domestic enteral nutrition infusion through the gastrostomy tube are selected, including intermittent bolus injection, intermittent drip infusion and continuous infusion. Wherein, for the patients who carry out the gastric feeding and keep somewhere the gastrostomy tube, the patients who can move about or can take care of oneself suggest to use the intermittent bolus injection mode, which is more in line with the human physiology 'dun take' feeding mode, and is convenient for the patients to better return to the society. The gastrostomy tube is about 20cm long outside the abdominal wall. If the gastrostomy tube can be maintained correctly, the gastrostomy tube can be replaced after being used for about 2 to 3 years.

However, it has been found clinically that for patients who administer intermittent bolus injections, the following problems are common to affect gastrostomy tube use:

1. the joint of the large bell mouth of the gastrostomy tube is broken: the nutrition liquid extravasation during the injection of the syringe is caused by the mechanical damage caused by frequently connecting the needle tube syringe for a long time, and the injection is influenced.

2. The joint of the large bell mouth of the gastrostomy tube becomes loose, the joint cover is not tight, and the joint is easy to be taken off: the device is related to the long-term frequent forced connection of a needle tube injector and the enlargement, and is easy to cause the loosening of a cover and the outflow of gastric juice and nutrient solution.

3. Rupture of the gastrostomy tube: there are 2 causes of breakage: firstly, some brands of gastrostomy tubes are provided with a switch clamp, and the mechanical damage to the gastrostomy tube is caused by repeatedly switching the switch clamp, so that the gastrostomy tube is broken. Secondly, the tube of some brands of gastrostomy tubes is not provided with a clamp, and some patients and family members have bad habit of folding the catheter by repeated external force during enteral feeding, and the broken part of the gastrostomy tube is often at the repeated folding part. The habit of folding the catheter by patients and family members is caused by worry that the abdominal pressure of the patients is high or gastric retention causes the nutrient solution and gastric juice in the intestines to flow out through the gastrostomy tube during the operation.

4. The external length of the abdominal wall of the gastrostomy tube is short: is not conducive to self-care patient operation.
