Abstract
The utility model discloses a modified three-channel double-balloon catheter for a gastric balloon, and relates to medical instruments. The modified three-channel double-balloon catheter comprises a three-channel catheter (1), a gastric balloon (2) and an esophageal balloon (3). The gastric balloon (2) and the esophageal balloon (3) are fixed at one end of the three-channel catheter (1) which comprises a stomach catheter lumen channel (11), a gastric balloon lumen channel (12) and an esophageal balloon lumen channel (13). The gastric balloon lumen channel (12) is communicated with the gastric balloon (2), while the esophageal balloon lumen channel (13) is communicated with the esophageal balloon (3). The gastric balloon (2) is heart-shaped when being inflated. By the arrangement, the gastric balloon is heart-shaped after being inflated, so that a superior border (sunken part of the heart-shaped gastric balloon) of the gastric balloon is matched with a vault-shaped curvature of fundus of a stomach so as to achieve the action of pressing varicose veins of the fundus of the stomach.
Description
Technical field
This utility model relates to medical apparatus and instruments, more particularly, relates to Sengstaken-Blakemore tube.
Background technology
Sengstaken-Blakemore tube is mainly used in the hemorrhage hemostasis by compression of breaking of cirso-at the bottom of the esophagus and stomach.Sengstaken-Blakemore tube comprises three lumens, gastric qi capsule and esophageal balloon, and gastric qi capsule and esophageal balloon are attached to an end of three lumens, and three lumens are made of the tract of a stomach catheter, the tract of gastric qi ductus bursae and the tract of esophageal balloon catheter.Insert Sengstaken-Blakemore tube by per nasal, respectively at the inflation of gastric qi capsule, tractive, esophageal inflatable balloon, to reach hemostasis by compression to cirso-at the bottom of the esophagus and stomach.
Be spindle after the existing gastric pouch inflation, can not be close to the curvature of fornix type at the bottom of the stomach, can not reach effect, and the eccentric state of part gastric pouch, air bag are big inadequately cirso-hemostasis by compression at the bottom of the stomach, be not enough to fully oppress varicose blood vessel at the bottom of the stomach, can not play evenly the fully effect of compressing.And in the clinical slotting Sengstaken-Blakemore tube process, because of two air bags have obvious resistance by nasal cavity, clinical in when inserting Sengstaken-Blakemore tube easily by difficulty or give a discount, cause and insert failure even increase the weight of hemorrhage.
Summary of the invention
The purpose of this utility model is to provide a kind of gastric qi capsule modified form Sengstaken-Blakemore tube of being close to fornix type at the bottom of the stomach.
This utility model is that the technical scheme that is adopted that achieves the above object is: a kind of gastric qi capsule modified form Sengstaken-Blakemore tube, comprise three lumens, gastric qi capsule and esophageal balloon, gastric qi capsule and esophageal balloon are fixed on an end of three lumens, three lumens comprise a stomach catheter tract, gastric qi ductus bursae tract and esophageal balloon catheter tract, the gastric qi ductus bursae communicates with the gastric qi capsule, and esophageal balloon catheter communicates with esophageal balloon; The gastric qi capsule is heart-shaped at inflated condition.
Preferably, the front end of described three lumens is provided with the opening that communicates with the stomach catheter tract.
Be heart-shaped after the gastric qi capsule of the present utility model inflation, gastric qi capsule upper limb (heart-shaped recess) coincide with fornix sample curvature at the bottom of the stomach, to reach the effect of cirso-at the bottom of the compressing stomach; With the hardness that increases Sengstaken-Blakemore tube and press close to pharyngeal rear wall, be beneficial to the insertion of Sengstaken-Blakemore tube by built-in seal wire.
Description of drawings
Fig. 1 is the sketch map of this utility model preferred embodiment;
Fig. 2 is the gastric qi capsule generalized section of this utility model preferred embodiment;
Fig. 3 is three lumen generalized sections of this utility model preferred embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, a kind of gastric qi capsule modified form Sengstaken-Blakemore tube, comprise three lumens 1, gastric qi capsule 2 and esophageal balloon 3, gastric qi capsule 2 and esophageal balloon 3 are fixed on an end of three lumens 1, three lumens 1 comprise a stomach catheter tract 11, gastric qi ductus bursae tract 12 and esophageal balloon catheter tract 13, gastric qi ductus bursae 12 communicates with gastric qi capsule 2, and esophageal balloon catheter 13 communicates with esophageal balloon 3; Gastric qi capsule 2 is heart-shaped at inflated condition.Be heart-shaped after 2 inflations of gastric qi capsule, gastric qi capsule 2 upper limbs (heart-shaped recess) coincide with fornix sample curvature at the bottom of the stomach, reach the effect to cirso-hemostasis by compression at the bottom of the stomach.
The wall thickness of described gastric qi capsule 2 begins to the end progressive additive away from esophageal balloon from an end of contiguous esophageal balloon.The gradual change of gastric qi capsule 2 wall thickness more easily forms heart-shaped when making 2 inflations of gastric qi capsule.
The capacity of described gastric qi capsule 2 is 400ml.Increase the air bag capacity to 400ml, to reach the effect of cirso-at the bottom of the compressing stomach.
As shown in Figure 1, the front end of described three lumens 1 is provided with the opening 14 that communicates with the stomach catheter tract.The Sengstaken-Blakemore tube front end has the opening that communicates with the stomach tube chamber, and the seal wire that is suitable for needing to carry out the exchange of Sengstaken-Blakemore tube seal wire in clinical is inserted.With the hardness that increases Sengstaken-Blakemore tube and press close to pharyngeal rear wall, be beneficial to the insertion of Sengstaken-Blakemore tube by built-in seal wire.Also can adopt another way, as shown in Figure 3, be provided with seal wire 15 along its length in described three lumens, 1 tube wall; With the hardness that increases Sengstaken-Blakemore tube and press close to pharyngeal rear wall.
As shown in Figure 3, described three lumens 1 are pipe, comprise tract and two tracts that the cross section is a quadrant that a cross section is a semicircle, and gastric qi ductus bursae and esophageal balloon catheter are respectively the quadrant tract, and stomach catheter is the semicircle tract.Stomach catheter mainly plays the usefulness of liquid in the discharging stomach, so caliber is wanted greatly.Gastric qi ductus bursae and esophageal balloon catheter mainly are that caliber can be littler to the usefulness of gastric qi capsule and esophageal inflatable balloon venting, and also have that the effect caliber of air pressure is little can not to be stopped up yet.
Above content be in conjunction with concrete better embodiment to further describing that this utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.Scope of the present utility model is represented by claims, and the whole alternate embodiment that fall into these claim implications should be included in this utility model.
