Abstract
A cardia anti-tearing pressure reducing device relates to the technical field of medical instruments, and comprises a receiving pipe and a pressure reducing pipe; the pressure reducing pipe is a straight pipe which is communicated up and down, the inner diameter of the accommodating pipe is larger than the outer diameter of the pressure reducing pipe, so that the pressure reducing pipe can be accommodated in a pipe cavity of the accommodating pipe, a first taper pipe is fixed at the upper end of the pressure reducing pipe, and a second taper pipe is fixed at the lower end of the pressure reducing pipe; first taper pipe, second taper pipe link up from top to bottom and have elastic soft taper pipe, the upper end mouth of pipe of the narrow end mouth of pipe and the decompression pipe of first taper pipe butt joint, the lower extreme mouth of pipe of the narrow end mouth of pipe and the decompression pipe of second taper pipe butt joint to first taper pipe, second taper pipe can both radially contract the back and take in the lumen of holding the pipe. The device provided by the utility model is used in cooperation with an esophageal endoscope.
Description
Technical Field
The utility model relates to a medical appliance technology, in particular to a cardia anti-tearing pressure reducing device technology.
Background
During the esophageal endoscopic treatment, the esophagus of a patient needs to be frequently inflated during the operation due to the requirement of clear exposure of the operation field, which easily causes the patient to have bleeding due to tearing of cardia and gastric mucosa caused by excessive gas in the stomach.
In order to avoid the above risks, in the esophagoscopy, the gastroscope is inserted into the stomach at intervals to suck the gas, and then the gastroscope is moved back to the operation site (esophagus), and the operation is repeated many times, which brings great inconvenience to the operation and interferes with the operation.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a cardia anti-tear pressure relief device that can alleviate stomach pressure in the esophagus scope art, make things convenient for doctor's operation is provided.
In order to solve the technical problem, the utility model provides a cardia anti-tear pressure reducing device, its characterized in that: comprises a storage tube and a decompression tube;
the pressure reducing pipe is a straight pipe which is communicated up and down, the inner diameter of the accommodating pipe is larger than the outer diameter of the pressure reducing pipe, so that the pressure reducing pipe can be accommodated in a pipe cavity of the accommodating pipe, a first taper pipe is fixed at the upper end of the pressure reducing pipe, and a second taper pipe is fixed at the lower end of the pressure reducing pipe;
first taper pipe, second taper pipe link up from top to bottom and have elastic soft taper pipe, the upper end mouth of pipe of the narrow end mouth of pipe and the decompression pipe of first taper pipe butt joint, the lower extreme mouth of pipe of the narrow end mouth of pipe and the decompression pipe of second taper pipe butt joint to first taper pipe, second taper pipe can both radially contract the back and take in the lumen of holding the pipe.
Further, the inner diameter of the first taper pipe butt pipe orifice is smaller than that of the second taper pipe butt pipe orifice.
Furthermore, a plurality of elastic wires are fixed on the pipe wall of the second taper pipe, and the elastic wires are uniformly distributed along the circumferential direction of the second taper pipe.
The utility model provides a cardia anti-tear pressure relief device can stretch into the second taper pipe in the stomach through the pincers way of gastroscope, and the bellmouth that the second taper pipe is expanded is convenient for gas in the stomach to discharge fast, and negative pressure aspirator can be connected to external first taper pipe, improves gaseous exhaust velocity in the stomach, can play the decompression effect to the disease stomach, avoids the excessive expansion of cardia mucosa and tears the hemorrhage that leads to, makes things convenient for doctor's operation.
Drawings
Fig. 1 is a schematic structural diagram of a cardia anti-tear pressure relief device according to an embodiment of the present invention.
Detailed Description
The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.
As shown in fig. 1, the embodiment of the present invention provides a cardia anti-tear pressure reducing device, which is characterized in that: comprises a storage tube 1 and a decompression tube 2;
the containing pipe 1 and the pressure reducing pipe 2 are straight pipes which are communicated up and down, and the inner diameter of the containing pipe 1 is larger than the outer diameter of the pressure reducing pipe 2, so that the pressure reducing pipe 2 can contain a pipe cavity of the containing pipe 1, a first taper pipe 3 is fixed at the upper end of the pressure reducing pipe, and a second taper pipe 4 is fixed at the lower end of the pressure reducing pipe;
The embodiment of the utility model provides an it decompresses to gas in the stomach to be arranged in the esophagus scope art, its using-way as follows:
the first taper pipe and the second taper pipe are firstly extruded to be contracted radially, then the first taper pipe and the second taper pipe are taken in the pipe cavity of the containing pipe together with the decompression pipe, then the containing pipe is inserted from the forceps channel of the gastroscope, the end where the second taper pipe is arranged extends into the stomach of the patient, the end where the first taper pipe is arranged outside the patient body, then the first taper pipe is propped by the push rod, the containing pipe is withdrawn from the forceps channel of the gastroscope, after the containing pipe is withdrawn, the first taper pipe and the second taper pipe can return to the taper state under the action of elastic force, gas in the stomach can rapidly enter the decompression pipe through the flared opening with the expanded second taper pipe, and then the gas is discharged outside the body through the decompression pipe, the decompression function can be realized on the stomach of the patient, the bleeding caused by excessive expansion and tearing of the cardia mucosa can be avoided, the first taper pipe outside the stomach can be connected with the negative pressure aspirator, the discharge speed of the gas in the stomach can, and the upper part is thin and the lower part is thick, and the endoscope can be directly pulled out of the body through a gastroscope clamping passage after use.
Claims (3)
