Abstract
The utility model relates to a pressure-measuring catheter for digestive systems, which comprises a tube body, a rubber sac fixed at one end of the tube body, a connecting tube connected at the other end and a tube connecting head, wherein at least 6 chambers are arranged in the tube body, the bigger chamber arranged at the center is a pouring chamber, and the small chambers arranged at the periphery are pressure-measuring chambers. One end of the pouring chamber and one end of each pressure-measuring chamber are respectively communicated with the tube connecting head, the other end of the pouring chamber is communicated with a guiding head of the rubber sac, and the other end of each pressure-measuring chamber is communicated with side holes which are arranged on the tube body at the position near the guiding head. The side holes can be positioned on the same radial section of the tube body, and can also be arranged on the tube wall of the catheter in spiral arrangement. The utility model can be used in clinic to realize the operations of the digestive system of pouring, gradient pressure measurement, compliant perception, vector pressure measurement, etc. The diagnoses of dyskinesia of the digestive system and the detection of the power of the muscular movement can be realized, and the catheter has the advantages of simple integral structure, convenient processing and safe and convenient operation. The utility model is particularly suitable for popularization and application in medical clinic.
Description
Technical field
This utility model belongs to the clinical treatment utensil, particularly relates to and is used for perfusion or gaging digestive system pressure catheter in a kind of insertion digestion.
Background technology
It is relevant with digestive system motor disorders and the variation of gut hormone level that a lot of diseases are arranged on the clinical medicine at present, and is used to check that the means of this class disease of diagnosis are limited.The connection of the external porous of application at present pressure-measuring pipe is led measuring cell more and is detected the variation of gastrointestinal pressure.As former Soviet Union's patent " intestinal input probe ", wherein by elastic catheter, near the working area end of pipe hole is arranged, be convenient to nutraceutical entering, the working area end forms an enclosed cavity by horizontal diaphragm, is provided with freely positionable Metal Ball working cell in the chamber, and it is strong that this probe enters small intestinal, stimulate intestinal peristalsis promoting, measure gastrointestinal tract mucosa pressure and change.Its weak point is that pressure tap is limited, the darkest pressure variation that can only measure distal duodenum near small intestinal lumen, and the pressure measurement precision is lower, and conduit puts in place slowly.In the recent period, also there is use to become the perfusion pressure catheter of a branch of multi-cavity structure clinically by some bonding catheters, but because this type of guide-tube structure complexity, difficulty of processing is big and cost is high, and be unfavorable for that clinical expansion uses.
Summary of the invention
This utility model is used for perfusion or gaging digestive system pressure catheter for the technical problem that exists in the solution known technology provides in a kind of insertion digestion.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
The digestive system pressure catheter, the connection tube and the pipe joint composition that comprise a body, be fixed on the capsule of body one end and be connected the other end, it is characterized in that: design has 5 chambeies at least in described body, on tube body wall, be provided with side opening near the capsule position, its layout is: bigger chamber, center is a filling cavity, loculus around it is a pressure measuring cavity, one end of filling cavity and each pressure measuring cavity all is communicated with connection tube and pipe joint, the insertion end of filling cavity is communicated with capsule, and the insertion end far away of each pressure measuring cavity is communicated with the side opening that is arranged on the close capsule position of body.
This utility model can also adopt following technical measures:
9 chambeies also can have been designed in the described body.
Side opening layout on described tube body wall shape is in the shape of a spiral arranged.
But the side opening on the described tube body wall also layout on the same radial section of body.
Advantage and the good effect that the utlity model has are: this utility model is owing to can be designed to multi-cavity with conduit cavity, each chamber size Control is accurate, each chamber position of opening accurately, is not gone here and there the chamber, so the intestinal juice in the time of recording the variation of digestive system pressure changes, the pressure that this multi-cavity catheter can be measured digestive system changes.Can realize multiple operations such as perfusion, gradient pressure measurement, compliance perception and vector pressure measurement clinically to digestive system; Also can realize diagnosing gastrointestinal motility dysfunction and detect muscular movement power.The conduit overall structure is simple, be convenient to processing, and is easy to use and safe and reliable, is particularly conducive to medical clinical application.
