Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a gastroenteroscope anti-reflux three-way valve structure.
[ background of the invention ]
The current gastrointestinal endoscope biopsy port valve widely applied to clinic is a single inner cavity, and can not be compatible with accessories (an injection needle, a hemostatic clamp, a snare, a mucosa incision knife, a needle-shaped knife, a guide wire and the like) and water delivery functions at the same time, the accessories or water injection can only be used successively when the gastrointestinal endoscope biopsy port valve is used, but the gastrointestinal cavity is frequently washed repeatedly when the accessories are used clinically, and the single-cavity biopsy valve can not be matched with washing tools and accessories at the same time (the traditional biopsy valve can only be used with the accessories and the washing tools independently, and the accessories and the washing tools are required to be repeatedly disassembled, assembled and replaced and inconvenient at the same time), so that the treatment time is delayed, the inconvenience and the missed treatment time are caused to the clinical work, and the operation time is prolonged.
[ Utility model ] content
The to-be-solved technical problem of the utility model is to provide a gastroenterology anti-reflux three-way valve structure that can improve operation efficiency.
The purpose of the utility model is realized like this:
the utility model provides a gastroenteroscope prevents backflow three-way valve structure, includes the main entrance and locates the supplementary passageway of main entrance lateral part, the both ends of main entrance are equipped with respectively and are used for the gastroenteroscope that is connected with the gastroenteroscope to connect and are used for supplying the annex port that the annex got into, the one end of assisting the passageway with the main entrance is linked together and the other end is equipped with the flushing joint that is used for being linked together with the flushing tool, the main entrance with be equipped with respectively in the supplementary passageway to the check valve of the one-way circulation of direction that the gastroenteroscope connects.
According to the anti-backflow three-way valve structure for the gastrointestinal endoscope, the outer side of the flushing connector is provided with the outer clamping convex block for being connected with the flushing tool.
The anti-backflow three-way valve structure for the gastrointestinal endoscope is characterized in that the gastrointestinal endoscope joint is a wedge-shaped insertion part which is used for being inserted into a pincerlike interface of the gastrointestinal endoscope.
According to the anti-backflow three-way valve structure for the gastrointestinal endoscope, the one-way valve is a duckbill valve check valve.
According to the anti-backflow three-way valve structure for the gastrointestinal endoscope, the main channel and the auxiliary channel are integrally Y-shaped, and the inner diameters of the main channel and the auxiliary channel are 2.8mm-3.0 mm.
Through the utility model discloses can use annex and flushing tool simultaneously to improve the efficiency of operation, avoided the delay of operation opportunity, be equipped with the check valve in main entrance and the auxiliary passage respectively moreover, thereby effectively prevent water liquid refluence and pollute annex and flushing tool, effectively reduced medical cost, avoid cross infection and environmental pollution, ensure medical safety simultaneously.
[ description of the drawings ]
The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention.
[ detailed description ] embodiments
The utility model provides a gastroenteroscope prevents backflow three-way valve structure, include main entrance 1 and the supplementary passageway 2 of locating the 1 lateral part of main entrance, the both ends of main entrance 1 are equipped with respectively and are used for the intestines and stomach scope that is connected with the intestines and stomach scope to connect 11 and be used for supplying the annex port 12 that the annex got into, the one end of supplementary passageway 2 is linked together with main entrance 1 and the other end is equipped with the flushing joint 21 that is used for being linked together with the flushing tool, be equipped with the check valve 3 to the one-way circulation of direction that intestines and stomach scope connects 11 in main entrance 1 and the supplementary passageway 2.
The outside of the flushing nipple 21 is provided with a snap-in projection 4 for connection with a flushing tool.
The gastroscope adapter 11 is a wedge-shaped insertion portion for insertion into the forceps-shaped interface of the gastroscope.
In order to effectively prevent water liquid from flowing back, the check valve 3 adopts a duckbill check valve.
The main channel 1 and the auxiliary channel 2 are of Y-shaped structures integrally, and the inner diameters of the main channel 1 and the auxiliary channel 2 are 2.8mm-3.0 mm.
The utility model discloses during the use, in the forcipated interface with gastrointestinal scope joint 11 disect insertion gastrointestinal scope, with the washing connector 21 through joint lug 4 with wash tools (the wash tools can be syringe or transfusion system) corresponding interface joint be connected, with corresponding annex (according to actual operation needs, the annex can be for syringe needle, hemostatic clamp, snare, mucosa incision sword, needle-like sword, seal wire etc.) through annex port 12 and main channel 1 and business turn over gastrointestinal scope in order to carry out corresponding gastrointestinal operation. When carrying out normal operation, the annex gets into the intestines and stomach mirror through main entrance 1 and arrives patient internal in order to accomplish corresponding stomach and intestine operation, when needs wash the gastrointestinal cavity when going on, direct will wash the interior washing water of instrument through supplementary passageway 2 inject into can, need not to carry out the dismouting change to annex and washing instrument repeatedly, it is very convenient.
