Description

A disposable electronic resetter and method for pediatric intussusception enema

Technical field

The present invention relates to an electronic resetter and a method, in particular to a disposable electronic resetter and method for pediatric intussusception enema.

Background technique

Intussusception refers to intestinal obstruction caused by a certain segment of intestinal tube and its corresponding mesentery being invaginated into the adjacent intestinal lumen. It is the most common complication in infants and young children. The treatment methods of this disease are divided into surgical treatment and non-surgical treatment. And because surgical treatment has many complications, it is often not accepted by the families of children with the disease. On the contrary, non-surgical treatment has always been the first choice for the treatment of intussusception because it does not require surgery, has few complications, and has a high success rate. Among the existing non-surgical methods, hydraulic enema reduction under ultrasound is currently the most widely used. Hydraulic enema reduction under ultrasound is a non-surgical treatment with the help of color ultrasound and electronic resetter. The main process is: using the transanal enema method, applying the developed anal canal with a balloon at the front end, inserting it into the anus about 4cm and injecting 5-10ml of air The air bag is expanded and fixed; after heating the enema solution to 35°C, the enema solution is squeezed through the anal canal into the small intestine of the infant by squeezing the water-filled balloon, and the intussusception is reset through the impact of water pressure; through ultrasound imaging Determine the reduction of intussusception.

The traditional intussusception enema reducer has a purely mechanical structure, as shown in Figure 1, including anal canal 1, pressure relief main pipe 4, enema tube 8, pressure relief pull ring 5 and other components. The rear end of the anal canal 1 is connected to the enema tube 8, and the enema pressure is displayed by the pressure gauge 2. During treatment, the doctor needs to inject physiological saline into the enema tube 8 and the anal canal 1 through the water injection balloon 7 on one side, and constantly observe the water pressure displayed in the pressure gauge 2 on the other side. When the water pressure exceeds the predetermined value, the doctor must immediately pull to release the pressure. The pull ring 5 is used to release the pressure, so that the enema fluid can be discharged through the discharge tube 3; in addition, another doctor is required to observe the reset situation via B-ultrasound. When the B-ultrasound shows that the "concentric circle sign" disappears, water enters the small intestine, and the ileocecal valve moves like crab claws, stop the enema. After extracting the air in the air sac, pull out the anal canal and drain the enema fluid.

It can be seen that the existing technology still has the following problems to be solved:

1) Enema, pressure observation, and pressure relief all require manual operations by doctors. Not only are the operations cumbersome, but they are also prone to confusion. In severe cases, improper operations may even cause medical accidents;

2) Pressurization through water injection has the characteristics of one tight and one loose, which will cause unstable pressure input and can easily cause damage to the intestines of infants and young children.
