Description
Technical Field
The invention relates to the technical field of medical appliance manufacturing, in particular to a capsule type extraction tool for extracting small intestinal juice.
Background
At present, chemical tests on blood and body fluid are numerous, and imaging inspection technology of whole body organs is developed, but no instrument or method for extracting small intestine fluid and carrying out chemical test under physiological state is widely applied to clinic until now, and only a few experimental studies are carried out. Some of the research directions include using a capsule type liquid taking device, which is swallowed by a patient, opening an opening on a shell of the capsule type extractor after the liquid taking device reaches the small intestine to extract the small intestine liquid, and then closing the opening to discharge the liquid taking device through the anus to obtain the small intestine liquid in a physiological state. The capsule type liquid taking device in the experiment generally comprises a capsule-shaped shell, an opening is formed in the shell, a sealing piece used for sealing the opening is arranged in the shell, the sealing piece is connected with a power source through a mechanical transmission device, the mechanical transmission device and the power source are connected with a control system to control opening and closing of the sealing piece and time, the sealing piece, the mechanical transmission device, the power source and the control system are all required to be designed in the shell of a small capsule, and therefore the devices are required to be miniature, the manufacturing cost is quite high, the space for containing small intestinal juice in the shell is quite small, the small intestinal juice extracted at one time cannot meet the requirements of clinical experiments, and the capsule-shaped liquid taking device cannot be applied to clinic.
Disclosure of Invention
The invention aims to provide a capsule small intestinal juice extractor to solve the problems of complex structure, high cost and insufficient liquid extraction amount of the existing small intestinal juice extractor.
In order to solve the problems, the technical scheme of the invention is as follows: the capsule small intestinal juice extractor comprises a capsule-shaped shell, wherein an opening is formed in the shell, a sealing piece used for sealing the opening is arranged in the shell, a layer of enteric film for sealing the opening is arranged outside the opening of the shell, the sealing piece is fixed in the shell through a connecting wire and hard candies at the other end of the connecting wire, and the sealing piece is connected with a pulling sealing piece for sealing the opening rubber band.
In the above technical solution, a more specific solution may be: the sealing pieces are two and arc-shaped, the sealing pieces are respectively arranged on two sides of the opening through the sliding rings on the inner walls of the two ends of the shell, each sealing piece is connected through the respective connecting wire, the two connecting wires are connected through the hard candy in a solidifying manner, and the sealing pieces are connected with the bulges on the two sides of the opening in the shell through the rubber bands.
Further: the casing comprises a cylinder in the middle and spherical plastic sealing covers at two ends of the cylinder, the enteric film is arranged outside the cylinder and connected with the spherical plastic sealing covers, the opening is arranged in the middle of the casing, and the connecting line is supported in the middle of the casing through ribs in the casing.
The enteric film is a coating film which is dissolved only under the small intestinal fluid.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
the capsule small intestinal juice extractor adopts a layer of enteric film arranged outside the opening of the shell to control the extractor to open the opening after the small intestinal juice dissolves the enteric film, the small intestinal juice enters the shell through the opening of the shell, when the small intestinal juice gradually enters the shell, the hard candy fixing the connecting wire is dissolved, so that the fixing function of the connecting wire is invalid, the sealing piece seals the opening of the shell by the tension of the rubber band, the small intestinal juice in the shell is isolated from the outside, and the extractor is discharged from the anus under the promotion of gastrointestinal peristalsis; this capsule intestinal juice extractor simple structure, it is with low costs, the space holding capacity in the casing is relatively big moreover, once can extract sufficient liquid measure and carry out clinical examination, and it is very convenient to use, has broken through the technical bottleneck in this field, probably realizes extracting intestinal juice and carrying out clinical examination under physiological state, opens up new research field for medical science.

FIG. 3 is a cross-sectional view B-B of FIG. 1;
fig. 4 is a cross-sectional view taken along line C-C of fig. 1.
Detailed Description
The embodiments of the invention will be described in further detail with reference to the accompanying drawings:
the capsule small intestinal juice extractor shown in fig. 1 to 4 comprises a capsule-shaped shell, the shell comprises a cylinder 2 in the middle and spherical plastic sealing covers 4 connected with two ends of the cylinder 2 through threads, an opening 2-1 is arranged on the shell, the opening 2-1 is arranged in the middle of the shell, an enteric film 1 for sealing the opening is arranged outside the opening 2-1 of the shell, and the enteric film is a coating film which is dissolved under small intestinal juice. The enteric-coated membrane 1 is arranged on the outer surface of the cylinder 2 and is connected with a spherical plastic sealing cover 4, the shell is provided with sealing pieces 5 at the opening 2-1, two ends of the cylinder 2 of the shell are respectively provided with a sliding ring 10 fixed in the cylinder 2, the sealing pieces 5 are provided with two pieces which are arc-shaped and are respectively arranged at the upper side and the lower side of the opening 2-1 through the sliding rings 10 on the inner walls of the two ends of the shell, so that the sealing pieces 5 at the upper side and the lower side can slide in a gap between the sliding ring 10 and the cylinder 2, one side of the middle part of the sealing piece 5 is fixed in the shell through a connecting wire 9 and a hard candy 3 at the other end of the connecting wire 9, each sealing piece 5 is connected through a respective connecting wire 9, the two connecting wires 9 are solidified and connected through the hard candy 3, the connecting wire 9 is supported on the inner wall of the middle part of the shell through a rib 6 in the shell, the cylinder 2, two ends of the sealing sheet 5 are provided with extending parts 5-1, and the extending parts 5-1 are connected with bulges 8 at two sides of the opening 2-1 in the shell through rubber bands 7.
