Abstract
The utility model relates to a backflow prevention type esophagus supporting tube for medical use. The existing esophagus supporting tube is a straight barrel-shaped hollow tube and is easy to slide in an esophagus. Besides, the existing esophagus supporting tube can not prevent gastric fluid from flowing backwards. The utility model is composed of a tube body (1), a funnel-shaped outlet (4) and a funnel-shaped inlet (7). A spring (2) is buried in the wall of a tube body. The complication caused by the backflow of the gastric fluid can be effectively prevented because a backflow devices (3) and (6) are additionally arranged. The utility model is particularly suitable for the support of a cardia point. The external wall of the funnel-shaped outlet (4) is provided with an annular convex part which can prevent the supporting tube from sliding in the esophagus. The utility model provides a safe backflow prevention type esophagus supporting tube for patients who can not eat because of the stenosis of the esophagus or the stenosis of the cardia, even the obstruction, etc.
Description
This utility model relates to a kind of therapeutic medical esophagus stay pipe, is specially adapted to the counnter attack streaming esophagus stay pipe of using when esophagus or preventricular stenosis patient expand esophagus.
Esophagus that a variety of causes causes or preventricular stenosis even block, patient can not take food and cause suffering, threat to life.Must be for keeping patient to take food water inlet with esophagectasia, clinically now adopt the method for putting the esophagus stay pipe to alleviate to block.The esophagus stay pipe that has now adopted clinically is a straight-cylindrical hollow tube chamber, easily slides such stay pipe in esophagus, do not prevent the device of liquid reverse flow, often lead to complications, as reflux esophagitis, aspiration pneumonitis etc., the more inapplicable cardia place nearer apart from stomach supports.
The purpose of this utility model provides a kind of, can stop gastric liquid reverse flow effectively, also can be seated in the cardia place, and the counnter attack streaming esophagus stay pipe that is difficult for sliding in esophagus.
For achieving the above object, the scheme that this utility model adopts is: in supporting tube wall, the circular hollow esophagus is embedded with the stainless steel silk spiral spring frame, and with the support force of increase tube chamber, thus the body of formation stay pipe.The outlet of falred entrance and infundibulate is set respectively at the body two ends, this falred entrance and body driving fit are sticking, osculum is opened in tube cavity, this infundibulate outlet is arranged on the body other end, big mouthful bonding with the body driving fit, the osculum opening part of its described falred entrance and infundibulate outlet is an antireflux device, it be by one can folding thin film realize that the opposite direction that stops gastric juice flows, and with body driving fit abutting edge one annular protrusion is arranged for big mouthful in the infundibulate outlet, support body in intraesophageal slip to prevent esophagus.
The advantage of counnter attack streaming esophagus stay pipe of the present utility model is: [1] is owing to taked the antireflux device can stop gastric liquid reverse flow effectively, prevent the generation of concurrent reflux esophagitis and aspiration pneumonitis, so also can be seated in the cardia place nearer safely apart from stomach.[2] because the outer wall of this esophagus stay pipe has an annular protrusion, can prevent that stay pipe from sliding in esophagus.
Below in conjunction with accompanying drawing this utility model embodiment is described in further detail.
Fig. 1 is a counnter attack streaming esophagus stay pipe structural representation of the present utility model.
This utility model counnter attack streaming esophagus stay pipe is made up of body " 1 ", falred entrance " 7 ", infundibulate outlet " 4 " as shown in Figure 1, rustless steel spiral spring frame " 2 " is arranged to increase the support force of tube wall in the tube body wall, guarantee that tube chamber is unobstructed indeformable, the suitable clinical patient of the length of body and thickness needs and decides.End at body is provided with a falred entrance, and is bonding with the body driving fit, and its osculum is opened in the tube chamber.Osculum opening part bonding can folding thin film " 3 ", its size is identical with osculum.At the other end of body one infundibulate outlet " 4 " is set, big mouthful bonding with the body driving fit, at the abutting edge outer wall one annular protrusion " 5 " arranged, and can increase the resistance with esophageal wall, prevents to slide in esophagus.Osculum opening part bonding " 1 " can folding thin film " 6 ", size is identical with osculum.This counnter attack streaming stay pipe places human body esophagus place, just with narrow esophagectasis.When patient took food liquid, liquid entered from falred entrance " 7 ", this moment the osculum opening part the antireflux device---thin film " 3 " is washed open by liquid, make liquid pass through body smoothly; In like manner, when it entered infundibulate outlet " 4 ", the antireflux device of its osculum opening part---thin film " 6 " was washed open by liquid, and liquid enters gastric.Otherwise, during gastric liquid reverse flow, the thin film of osculum opening part is rushed at opening part, has blocked opening, liquid can't pass through, thereby prevented the liquid reverse flow effectively, cardia is very near apart from stomach, is again the esophageal stricture place, can prevent effectively during physiological status that gastric juice is counter flows, when carcinoma of gastric cardia causes esophageal stricture, use clinical existing esophagus stay pipe to expand,, make existing esophagus stay pipe can not be used for cardia owing to there is not antireflux device gastric liquid easily to cause anti-stream.And counnter attack streaming esophagus stay pipe of the present utility model, can prevent effectively that gastric juice is counter flows, thereby being used for the cardia esophagus, to support expansion be safe and reliable.
Claims (4)
1, a kind of medical counnter attack streaming esophagus stay pipe, it comprises body, it is characterized in that the body two ends also are provided with the outlet of falred entrance and infundibulate respectively, and this falred entrance and body driving fit are bonding, and osculum is opened on tube cavity; This infundibulate outlet is arranged on the body other end, and big mouthful bonding with the body driving fit; Body is a circular hollow tube, is embedded with the stainless steel silk spiral spring frame in this tube wall.
2, counnter attack streaming esophagus stay pipe according to claim 1 is characterized in that the infundibulate outlet has an annular protrusion with body driving fit abutting edge outer wall for big mouthful.
