As shown in fig. 1, a peristaltic structure for intestinal examination includes: the front bag 1, the middle bag 2, the rear bag 3, the front bag inflation tube 4, the middle bag inflation tube 5 and the rear bag inflation tube 6. The front bag 1, the middle bag 2 and the rear bag 3 are connected in sequence and are not communicated with each other. The front bag inflation tube 4 is used for inflating and deflating the front bag 1, the middle bag inflation tube 5 is used for inflating and deflating the middle bag 2, and the rear bag inflation tube 6 is used for inflating and deflating the rear bag 3. The tail ends of the front bag inflation tube 4, the middle bag inflation tube 5 and the rear bag inflation tube 6 are respectively provided with a connector matched with the inflating device, and the type of the connector can be correspondingly selected according to the type of the inflating device.
The anterior capsule 1 is composed of at least one anterior capsule cavity. Preferably, the anterior capsule 1 is composed of 4-10 anterior capsule cavities, each of which is equal in volume. When the front bag cavity is a plurality of, a plurality of front bag cavities are uniformly distributed around the axial center line of the geometrical shape of the front bag in an annular array manner, and the adjacent front bag cavities are communicated with each other. Referring to fig. 2, fig. 2 illustrates a case where the anterior capsule 1 is composed of six anterior capsule cavities 11. The number of the front air bag inflation tubes 4 is one, and the front air bag inflation tubes are connected with any one front air bag cavity. When the front airbag 1 is fully inflated by the front airbag inflation tube 4, each front airbag cavity is filled with gas because the front airbag cavities are communicated with each other. Compared with the condition of only one cavity, when the front bag 1 is of the multi-cavity structure, stress points which are more uniformly distributed on the intestinal tract are formed, the positioning effect in the intestinal tract after the front bag is inflated is improved, and the comfort level is improved.
The rear bag 3 is composed of at least one rear bag cavity, similar in structure to the front bag 1. Preferably, the posterior capsule 3 consists of 4-10 posterior capsule cavities, each of which is equal in volume. When the back bag cavity is a plurality of, a plurality of back bag cavities are around the axial centerline of the geometry of back bag and are arranged in an annular array, and adjacent back bag cavities are communicated with each other. Like the front bag 1, the rear bag is provided with one inflation tube 6 which is connected with any one of the rear bag cavities. The front bag 1 and the rear bag 2 both have the effect of propping against the intestinal tract when being inflated and positioning the self in the intestinal tract.
The middle bag 2 is composed of at least two middle bag cavities which are not communicated with each other, the number of the middle bag inflation tubes 5 is the same as that of the middle bag cavities, and each middle bag inflation tube is respectively communicated with one middle bag cavity.
In some embodiments, as shown in fig. 3, the middle bladder 2 is composed of two middle bladder cavities 21 and 22 with equal volumes, and the middle bladder cavity 21 and the middle bladder cavity 22 are symmetrically arranged around the axial center line of the geometric shape of the middle bladder.
In some embodiments, as shown in fig. 4, the central bladder 3 is composed of four central bladder cavities 23, 24, 25, 26 of equal volume, arranged evenly in an annular array around the axial centerline of the central bladder geometry.
The front bag 1, the middle bag 2 and the rear bag 3 are made of elastic medical materials, such as medical PE plastics, medical silica gel and medical rubber. Preferably, the front bag inflation tube 4, the middle bag inflation tube 5 and the rear bag inflation tube 6 are integrally bonded to the inner wall of each bag.
Further, the sizes of all parts in the peristalsis structure for intestinal examination can be set in a grading mode according to actual requirements. For example, the peristaltic structure may be sized accordingly for adult or pediatric bowel sizes to accommodate an adult or pediatric bowel examination. In addition, the peristaltic structure for the intestinal examination is not only suitable for the intestinal examination of the human body, but also can be used for the medical intestinal examination of animals such as tigers, elephants and the like.
The peristalsis structure for the intestinal examination of the invention peristaltically advances according to the following steps a to c:
a. the front sac is inflated to prop against the inner wall of the intestinal tract, and then the middle sac and the rear sac are deflated, so that the middle sac and the rear sac contract forwards.
b. The rear sac is inflated to prop against the inner wall of the intestinal tract, the front sac is deflated at the same time, and then the middle sac is inflated, so that the middle sac pushes the front sac to move forwards.
c. And (c) alternately repeating the step a and the step b, so that the peristaltic structure is advanced in a peristaltic manner.
The peristalsis structure for the intestinal examination of the invention turns according to the following steps:
when the peristalsis structure needs to be turned to a certain side, the middle bag cavity close to the side is inflated, and the middle bag cavity far away from the side is pumped. The middle bag 2 shown in fig. 3 is explained in detail by taking as an example a case where it is composed of a right middle bag chamber 21 and a left middle bag chamber 22: when turning to the left, the middle bag cavity 21 close to the right side is inflated, and then the middle bag cavity 22 close to the left side is exhausted, so that the left turning is realized; in the same way, when turning to the right side, the middle bag cavity 22 close to the left side is inflated, and then the middle bag cavity 21 close to the right side is pumped, so that the right turning is realized. The middle bag cavity body composed of four middle bag cavity bodies, namely, the upper middle bag cavity body, the lower middle bag cavity body, the left middle bag cavity body and the right middle bag cavity body, which are shown in the figure 4, can realize turning in all directions more accurately.
The above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any person skilled in the art should be able to substitute or change the technical solution of the present invention and its inventive concept within the technical scope of the present invention.
