A sheathed endoscope, includes: an endoscope and a disposable component. The disposable compartment protects the inner and outer surfaces of the endoscope. The disposable compartment includes: a cap of endoscope tip in the distal end of endoscope, a disposable tube for biopsy forceps, and an outside sheath capsule for endoscope shaft. The tip cap connects the sheath capsule and the disposable tube for biopsy forceps. There are multiple windows set on the lateral side of endoscope tip, wherein pills containing transparent fluid are placed somewhere in between of the tip cap and the distal end of endoscope. The pills will be crushed by co-fraction of the tip cap and the distal end of endoscope, to release the transparent fluid to fill in the space formed between the tip cap and the distal end of the endoscope. This disposable sheath compartment in the invention will cover all surfaces of the endoscope with disposable material, preventing contaminations on endoscope during endoscopy, meanwhile there is anti-glaring design, to prevent producing of glaring in the space formed between the tip cap and the distal end of endoscope.

The invention discloses a rhodiola rosea compound composition for treating peptic ulcer. The rhodiola rosea compound composition is a preparation prepared from the following active pharmaceutical ingredients in parts by weight: 4.2-7.2 parts of rhodiola rosea, 14-26 parts of poria cocos, 10.5-19.5 parts of dandelion, 10.5-19.5 parts of capillary artemisia, 10.5-19.5 parts of white atractylodes rhizome, 7-13 parts of pogostemon cablin, 7-13 parts of raw malt, and 3.5-6.5 parts of fructus amomi rotundus. The compound composition disclosed by the invention is exact in compatibility of medicines, quite less in medical ingredients, not only capable of ensuring medicine efficacy and reducing side effects, but also capable of effectively treating gastric ulcer, duodenal ulcer, and erosive gastritis, and provides a new administration choice for the clinical treatment of the peptic ulcer.

The invention relates to the field of medical equipment and application thereof, and provides a duodenum internal covering film. The duodenum internal covering film is made of biocompatible biodegradable or non-biodegradable material or / and hydrophobic material and is mainly composed of an elastic ampullar portion and a tubular portion. The ampullar portion comprises a biocompatible bionic micro array adhesion piece which can achieve strong adhesion in the force application direction, does not stab intestine tissues and is capable of achieving detachment and recovery easily. The adhesion piece is good in stability, strong in adaptability to material and shapes, good in self-cleaning performance, free of damage and pollution to the intestine tissues, and capable of achieving repeated adhesion and detachment and supporting other components mutually in functions. When intestinal tract contents move, the internal covering film can not be detached due to the fact that subvertical pulling force does not exist. When the duodenum bulb is expanded and inflated, the internal covering film can not be detached due to the fact that the internal covering film does not have opposite and subvertical pulling force, and in the process of recovery, the internal covering film can be detached and recovered easily through force applied in a subvertical mode. The duodenum internal covering film can be manufactured into the medical equipment which does not damage the intestine tissues and can prevent and cure fat and diabetes.

The invention discloses a pharmaceutical preparation used for treating erosive reflux oesophagitis, a gastroesophageal reflux disease, maintaining a long-term therapy to prevent the recurrence of oesophagitis for a cured patient, controlling the symptoms of gastroesophageal reflux diseases, eradicating helicobacter pylori jointly medicated with an appropriate antimicrobial therapy, healing duodenal ulcer related to helicobacter pylori infections and preventing the recurrence of peptic ulcer related to helicobacter pylori, and particularly relates to a prepared sustained-release oral formulation adopting esomeprazole magnesium as the ingredient. The pharmaceutical preparation aims to supplement the deficiency of the prior art and provide a sustained-release esomeprazole magnesium dropping pill. The sustained-release esomeprazole magnesium dropping pill overcomes the defects in the prior art effectively, guarantees no occurrence of an obvious quality change for the drug during the effective storage period and has the advantages of controllable release time, full release and high bioavailability simultaneously.

The invention provides an internal tectorial membrane for duodenum, and relates to a built-in degradable medical instrument in a digestive tract. The internal tectorial membrane can be made of biocompatible materials by electrospinning. The internal tectorial membrane is placed in the duodenum of a patient, not only can stop food from contacting with the intestinal mucosae of the patient during dissection, but also avoids affecting functions of cells of the intestinal mucosae physiologically, can be obtained by hybrid electrospinning or / and multi-layered electrospinning or / and core-shell electrospinning or / and dry-method electrospinning, and can be manufactured into a medical instrument which can reduce injury, prevent dropping, avoid being removed and restrain bounce and can be used for treating diabetes mellitus and adiposis.

The invention relates to a transpyloric device for accepting chyme from the stomach and conducting said chyme on in a bypass-like manner through a patient's duodenum; said device is held in place by balloon segments which sit on a preferably radially collapsible and self-erecting transpyloric conducting element; the filling level of the balloon segments, and thus the axial sealing force acting primarily on the shoulder surfaces of the pylorus or the surrounding area thereof, can be adjusted by the user, and the force applied to the stomach and duodenum structures adjoining the pylorus is reduced to a level that is permanently bearable for the organs even when the filling pressure of the segments rolling against each other is elevated. The invention also relates to an applicator for putting a bypass device of said type in place in the region of the transition from the stomach to the duodenum.

An endoscopically-deployable tissue-manipulation device including an elongate, generally tubular outer body having a proximal portion and a distal end portion that may be configured as sufficiently flexible to traverse the working channel of a flexible endoscope (e.g., side-viewing duodenoscope). The outer body may include an outer body lumen extending longitudinally between the proximal and distal portions. An anchoring structure of the device will include an elongate inner body that may extend through the outer body lumen and be configured to include a first linkage member attached to the inner body, a second linkage member that is pivotably attached to the first linkage member and to the outer body.

The invention discloses a gastric fluid director and a support thereof. The support is a reticulated tube formed by weaving woven wires, and comprises an upper support section and a lower support section, wherein the outer diameter of the upper support section is larger than that of the lower support section. The support can provide good support force and is fixed at the duodenum. The support has good compliance and fatigue resistance, has certain support force and certain flexibility, and can be stably fixed at the duodenum for a long time; the support can move along with the movement of the duodenum, but does not damage the wall of the duodenum. Furthermore, the support can be connected with a duodenal membrane tube so as to be used for treating metabolic diseases such as diabetes mellitus and obesity. The support is good in applicability, convenient in manufacturing technology, low in cost and rapid in production speed, and is used for the digestive tract; the support also can be connected with an implanted catheter.
