Experimental device for automatic simulation of gastrointestinal continuous digestion and application method

PendingCN110231437AStable pHReal-time monitoring of particle size changesMaterial analysisPylorusPh regulation
The invention provides a device capable of realizing automatic simulation of gastrointestinal continuous digestion and an application method of the device. The device comprises a stomach reactor, a stirrer, a constant-temperature water circulation system, a gastrointestinal fluid conveying system, a gastric emptying control device, an automatic pH titration device, a small intestine reactor and asample receiving device. According to the application method, to-be-digested food is conveyed into a stomach digester, stomach digestive fluid is input at a constant speed, the stirrer simulates stomach peristalsis, a micropore glass plate at the bottom of the stomach reactor simulates a pylorus to realize stomach "sieving emptying", the to-be-digested food is conveyed into a pH regulation chamberfor automatic pH regulation, small intestine digestion is simulated in the small intestine reactor provided with an internally-arranged latex sleeve, and the pressure-changing water circulation system is adopted to realize regular vibration of the latex sleeve so as to simulate the stomach peristalsis. Through the device and the application method, the whole reaction process can be continuous andautomatic under the situation that parameters are set; and moreover, the device is simple in structure, free of a complicated control system and easy to assemble and can be used to realize a digestion simulation experiment in a scientific research experiment.

Inflatable visual stomach tube traction device

The invention discloses an inflatable visual stomach tube traction device, and belongs to the field of medical instruments. Generally, for a non-surgical patient, bare-handed application of the gastrointestinal tube can only reach the stomach, the gastrointestinal tube is difficult to enter the small intestine through pylorus, and the gastrointestinal tube easily gets stuck when touching the bottom gastric varus area. The inflatable visual stomach tube traction device is characterized in that an air bag strap (3) is sleeved outside a combined guide air bag (2), the combined guide air bag (2) is fixedly connected with a sealing plug (4), the other end of the sealing plug (4) is sleeved with a sleeve (5), and the outer wall of the sleeve (5) is sleeved with a stomach tube (6); an endoscope (1) sequentially penetrates through the stomach tube (6), the sleeve (5), the sealing plug (4) and the combined guide air bag (2), and a camera is installed at the front end of the endoscope (1); and agroup of inflating pipes (7) are uniformly arranged at the periphery of the endoscope (1). The stomach tube traction device can bend and rotate, the degree of freedom is more flexible, and bending, twisting, rotating and other operations can be achieved through the control quantity of gas in different channels.

Traditional Chinese medicine used for treating gastrosis and preparation method thereof

The invention provides a traditional Chinese medicine used for treating gastrosis and a preparation method thereof. The traditional Chinese medicine comprises, by weight, 1 part of gizzard lining and 0.2 part of aloe powder. The preparation method includes the following steps: (1) removing impurities of the gizzard lining, soaking with water for 24-36 hours, taking the gizzard lining and cleaning, (2) drying the cleaned gizzard lining, frying slowly until the gizzard lining is plump, taking the gizzard lining out, adding the aloe powder rapidly, evenly mixing, sealing and storing for 24-48 hours, and smashing to obtain the traditional Chinese medicine used for treating the gastrosis. By means of the gizzard lining soaked with the aloe, the traditional Chinese medicine used for treating the gastrosis has large astringent and healing effects on stomach inflammation and ulcer cambiums. Besides, odor of the gizzard lining is removed, so special effects such as inflammation prevention, sterilization and stomach fortifying are enhanced. The medicine further has a function of inhibiting helicobacter pylori, and therefore treatment effects are remarkable. The traditional Chinese medicine is remarkable in treatment effect, safe, and efficient. Cure efficiency is 96.4%.
