Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to three chamber intestines and stomach negative pressure drainage tubes of STREAMING.
Background
The current gastrointestinal negative pressure drainage tubes have two types: one is a short single-cavity negative pressure drainage tube which can only drain the upper digestive tract; the other is a long single-cavity negative pressure drainage tube, the drainage range can reach the whole gastrointestinal tube including the colon and the rectum, and the drainage is more sufficient. The disadvantages are that: the single-cavity negative pressure drainage needs gastrointestinal retraction, and the drainage effect is not good enough; the gastrointestinal tract is easily damaged if the negative pressure is too large; cannot completely block the downward flow of digestive juice and cannot be used for preventing gastrointestinal anastomotic fistula.
In order to solve the defect of the single-cavity negative pressure drainage tube, a convection type three-cavity negative pressure drainage tube is designed. Because the drainage is convective, the gastrointestinal tract retraction is not needed during drainage, the drainage is sufficient, the intestinal obstruction symptom is rapidly relieved, and the gastrointestinal tract is not easy to be damaged; because the drainage is sufficient, the treatment and the enteral nutrition can be carried out simultaneously, thereby achieving the purpose of quick rehabilitation. The air bag structure can guide the drainage tube to the far end when the air bag structure is inflated, and the drainage tube is inflated to expand after reaching the target intestinal tract, so that digestive juice can be blocked from flowing downwards manually, and the digestive juice is prevented from corroding the fistula or the anastomotic stoma, and the anastomotic fistula is prevented and treated.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a to three chamber intestines and stomach negative pressure drainage tubes of STREAMING, the utility model discloses simple structure, design scientific and reasonable can relieve the intestinal obstruction symptom rapidly to be difficult to harm intestines and stomach, can also effectively break the digestive juice down-stream, avoid the digestive juice to the corruption of fistula or identical mouth, reach the prevention, treat identical fistula.
The technical scheme of the utility model:
the convective three-cavity gastrointestinal negative pressure drainage tube comprises a negative pressure tube, an air inlet tube and an air bag tube which are arranged side by side; the connecting ends of the negative pressure pipe and the air inlet pipe are provided with plugging covers; the negative pressure pipe is integrally communicated with the action end of the air inlet pipe, wherein the air inlet pipe is arranged around the port part of the negative pressure pipe in a surrounding way and is communicated through the side hole; the outer connecting end of the air bag pipe is provided with a one-way elastic valve; the action end of the air bag pipe is connected with an expandable and retractable air bag; the side opening is a plurality of to can let the intake pipe communicate with external and negative pressure pipe.
The utility model discloses a general concept: the negative pressure pipe, the air inlet pipe and the air bag pipe are arranged in parallel, so that the integrated operation in the operation process is facilitated, the problem that a plurality of devices need to be operated by medical staff at the same time is avoided, and the operation process is simple and convenient. The negative pressure pipe is communicated with the air inlet pipe through the side hole at the bottom, circulation is formed in the negative pressure process, the good negative pressure drainage effect can be achieved, the air inlet pipe is used for providing an external air source or flushing liquid, the flowing of air or liquid is maintained, and in the flowing process of the air or liquid, the internal air and digestive juice are brought out. And the integration of gasbag pipe sets up, not only can adjust the operation order and reach fixed effect on the one hand, avoids the operation of putting equipment such as needle tubing repeatedly to corresponding position among the current operation process, has improved the precision and has simplified the operating procedure, has further improved medical effect. The scalable inflation of gasbag passes through the effect of elasticity valve, and is beaten inside back of gasbag with outside small amount gas at the syringe, and the gasbag expands slightly, can guide the drainage tube toward the distal end, further aerifys the inflation after arriving the purpose intestinal, can be with the artificial digestive juice of blocking down flowing, avoids the digestive juice to the corruption of fistula or coincide mouth to prevention, treatment coincide fistula. The elastic valve is a one-way valve, and is visible everywhere in the prior art, and the common plastic duckbill one-way valve, diaphragm type one-way valve and plastic spring one-way valve have, pull out the syringe after, can guarantee that inside gas can not past reveal outward, has guaranteed the required volume of inflation.
Further, the inflatable and telescopic air bag at the action end of the air bag pipe can be replaced by a water bag.
Further, the blocking cover is a detachable closed cover body.
Furthermore, the air inlet pipe can be used for introducing air or liquid for flushing.
The utility model has the advantages that:
1. the negative pressure pipe, the air inlet pipe and the air bag pipe are arranged in parallel, so that the integrated operation in the operation process is facilitated, the problem that a plurality of devices need to be operated by medical staff at the same time is avoided, and the operation process is simple and convenient.
2. The negative pressure tube is communicated with the air inlet tube at the bottom through the side hole, circulation is formed in the negative pressure process, gastrointestinal tract retraction is not needed in drainage, drainage is sufficient, intestinal obstruction symptoms are rapidly relieved, and gastrointestinal tract injury is not easy.
3. The air bag structure can guide the drainage tube to the far end when the air bag structure is inflated, and the drainage tube is inflated to expand after reaching the target intestinal tract, so that digestive juice can be blocked from flowing downwards manually, and the digestive juice is prevented from corroding the fistula or the anastomotic stoma, and the anastomotic fistula is prevented and treated. Because the drainage is sufficient, the treatment and the enteral nutrition can be carried out simultaneously, thereby achieving the purpose of quick rehabilitation.
4. The elastic valve is a one-way valve, and after the injector is pulled out, the internal gas can be ensured not to leak outwards, so that the required volume of expansion is ensured.
5. The utility model has simple structure, scientific and reasonable design, no gastrointestinal retraction is needed during drainage, the drainage is sufficient, the intestinal obstruction symptom is rapidly relieved, and the gastrointestinal tract is not easy to be damaged; the air bag structure can artificially block digestive juice from flowing downwards, and prevents the digestive juice from corroding the fistula or the anastomotic stoma, thereby preventing and treating anastomotic fistula. Because the drainage is sufficient, the treatment and the enteral nutrition can be carried out simultaneously, thereby achieving the purpose of quick rehabilitation.
