Abstract
The utility model relates to a multipurpose gastrointestinal conformal tunnel, and solves the problems that the existing nutrient canal can not bear the gastrointestinal peristalsis force after being inserted into the gastrointestinal tract. An expandable film channel is connected onto a catheter, and the end part of the film channel towards the inserting end of the catheter and the catheter are fixed; at least one outlet is formed in the end part of the film channel, and an inlet end of the film channel and the catheter are fixed through an inlet dilator; the inlet dilator is an inflated elastic body or a memory alloy body, clings to the catheter wall when the inlet dilator is in a retraction state, and dilates the film channel after the inlet dilator dilates. After the film channel is inserted into the gastrointestinal tract along with the catheter, the inlet of the film channel is dilated by the inlet dilator, and the inlet dilator is fixed in an appropriate position, so that food chewed in an oral cavity can enter from the inlet, and then is discharged from the film channel, and the food can be conveyed to an appropriate position by reasonably determining the position of the outlet of the film channel, and thus the chewing physiological function can be realized while the nutrients are supplemented.
Description
Technical field
This utility model relates to medical instruments field, the conformal tunnel of especially a kind of multipurpose gastrointestinal.
Background technology
The injected gastrointestinal nutritive canal of existing domestic and international production and sales, drainage tube, delivery tube, compression hemostasis tube are of a great variety, Various Functions.Although various pipelines have himself characteristic advantage and the scope of application, also there are some common weak points.Various outer diameter tube mostly are 5-7mm, and internal diameter just rarely has and exceedes 5mm, can only splash into special expensive clear rare stream juice nutritional solution as enteral nutrition pipeline, and plugging easily occurs.
Although some nutritive canal has other functions, such as oxygen therapy pipeline can be housed simultaneously, or aspirate in addition the drainage of digestive tract internal hemorrhage, hydrops, pneumatosis, but there will be the phenomenon of plugging, and commercially available various nutritive canals are all merely supplied with patient's nutrition and do not have to consider how to discharge the demand of taking in unnecessary food to patient.
Even for nutritive canal has increased several functions, but used various pipe all lacks the effect of replying and bring into play human body alimentary canal self function.Can not per os diet as patient, just can not bring into play the physiological function of chewing, cause a negative effect that phase Digestion weakens.
Nutritive canal can not be agreed gastrointestinal peristalsis power after inserting in gastrointestinal cavity, has the drawback of abandoning gastrointestinal part physiological function.
Summary of the invention
The purpose of this utility model is to provide the conformal tunnel of a kind of multipurpose gastrointestinal, on conduit with expansion type thin film passage, after cavum nasopharyngeum inserts, thin film passage can be expanded and can adapt to gastrointestinal tract shape and size, thereby can bring into play the physiological function of chewing, food is input to correct position through chewing by the esophagus thin film passage of flowing through.
This utility model has solved existing nutritive canal and has been inserted into after gastrointestinal tract, can not agree the defect of gastrointestinal peristalsis power, provides a kind of multipurpose gastrointestinal conformal tunnel, and the thin film passage in tunnel is expanded and the gastrointestinal wall of fitting, and can pass on gastrointestinal peristalsis.
This utility model solves the technical scheme that its technical problem adopts: the conformal tunnel of a kind of multipurpose gastrointestinal, comprise the conduit that plays the hollow of guiding while inserting in gastrointestinal tract, on conduit, be connected with distensible thin film passage, thin film passage fixes towards end and the conduit of conduit insertion end, and offer at least one outlet in this end, thin film passage fixes by entrance dilator and conduit towards the end of tail end of conduit, and this end forms thin film feeder connection; Entrance dilator is Inflatable elastic body or memorial alloy body, and entrance dilator is close to catheter wall when contraction-like, and entrance dilator expansion rear distraction thin film passage also forms entrance.Conduit plays guiding function in tunnel inserts gastrointestinal tract time, supravasal thin film passage is brought in gastrointestinal tract simultaneously simultaneously, also just solve thin film passage softness and how to be inserted into the technical barrier in gastrointestinal tract, after thin film passage inserts in gastrointestinal tract, under the effect of entrance dilator, the entrance of thin film passage is strutted, as long as entrance dilator is fixed to suitable position, the food that chew in oral cavity just can enter from entrance, discharge from the outlet of thin film passage again, the position of rationally determining thin film channel outlet just can be transported to food suitable position, in supplementing the nutrients, can also bring into play the physiological function of chewing, thin film Passage Thin Walled, soft, after the expansion of entrance dilator, form a passage, this passage gastrointestinal wall of can fitting, thereby succession gastrointestinal peristalsis, especially the position that this thin film passage capable of being covers wound or should not contact with food, thereby play the effect of protection, entrance dilator is adjacent to conduit outer wall before not expanding, the resistance while reducing conduit insertion, entrance dilator is Inflatable elastic body, expands by inflating, and for memorial alloy body, expands by variations in temperature, while not having food to pass through, thin film passage withers flat, food by time, food can strut thin film passage and form the food passage of flowing through, the outlet of thin film passage can be overall diameter open architecture, appoints the full shaping of chyme, can also strut by the dilator of increasing export if necessary the outlet of thin film passage.
As preferably, the port of export of thin film passage is connected with export expansion device, and export expansion device is Inflatable elastic body or memorial alloy body, and export expansion device is close to catheter wall when contraction-like, and export expansion device expansion rear distraction thin film passage forms outlet.With the export expansion device of thin film passage, convenient size of establishing thin film channel outlet.
