1. the device comprises a catheter, 2, a filtrate cavity, 3, a pressing convex membrane, 4, an anti-backflow cavity, 5, a guide wire, 6, a guide wire port, 7, a guide wire port cover, 8, a liquid inlet cavity, 9, a diaphragm type check valve, 10, an anti-backflow device, 11, a catheter input port, 12 and a catheter tail end port.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
In this embodiment, as shown in fig. 1, the utility model provides a medical gastric tube, a catheter body 1, an anti-reflux cavity 4, a pressing convex membrane 3 and an anti-reflux device 10, wherein one end of the catheter body 1 is provided with a catheter input port 11, the other end of the catheter body 1 is provided with a catheter end port 12, the anti-reflux cavity 4 is arranged in the catheter body 1, and the pressing convex membrane 3 is arranged on the surface of the catheter body 1 and at a position corresponding to the anti-reflux cavity 4; the backflow prevention device 10 is communicated and installed on the catheter body 1 between the backflow prevention cavity 4 and the catheter input port 11.
The utility model discloses a prevent backflow chamber 4 with between the pipe input port 11 install in the pipe body 1 and prevent backflow device 10, can effectually avoid the infusion time air to get into filtrate chamber 8, if there is the gastric juice backward flow to get into filtrate chamber 8 simultaneously to it is more convenient when nursing the patient to make medical personnel, prevents the emergence of unnecessary medical risk.
In this embodiment specifically, prevent that backflow chamber 4 includes feed liquor chamber 2, filtrate chamber 8 and diaphragm type check valve 9, prevent that the inside setting in backflow chamber 4 is the inclined plane diaphragm type check valve 9, diaphragm type check valve 9 will prevent that backflow chamber 4 separates into filtrate chamber 8 with feed liquor chamber 2.
In this embodiment, as shown in fig. 2, a guide wire port 6 is disposed on the catheter body 1 between the anti-backflow cavity 4 and the catheter distal port 12, a distance between the guide wire port 6 and the catheter distal port 12 ranges from 60cm to 65cm, and a guide wire 5 is placed into the catheter body 1 from the guide wire port 6. When preparing to install medical stomach tube, take off the guide wire flap 7 that has on the guide wire mouth 6, will the one end of seal wire 5 is followed guide wire mouth 6 penetrates in the pipe body 1 and extend and be close to pipe end port 12, because guide wire 5 adopts hardness to compare in the pipe medical aluminum alloy that is harder slightly and make, when medical personnel inserted patient's esophagus with the stomach tube, because the stomach tube generally is polyurethane or silica gel material and makes, often the stomach tube is for taking place the condition of folding or bending in the esophagus, and be not convenient for medical personnel to operate, and can be under the prerequisite that reduces because the negative impact that the mistake brought for patient through guide wire 5 for medical personnel can put into patient's digestive system better with the guide of stomach tube through the guide wire. The end of the guide wire 5 close to the catheter end port 12 is in a hook shape or a vortex shape, and the catheter end port 12 is in an arc shape, so that secondary damage to the digestive system of a patient is prevented.
The anti-backflow cavity 4 is added on the catheter body 1, the diaphragm type check valve 9 in the anti-backflow cavity 4 can press the pressing convex membrane on the upper part of the anti-backflow cavity 4 to enable gastric juice to reenter the digestive system of a patient when the gastric juice flows back into the filtrate cavity 8, the anti-backflow cavity is separated into the filtrate cavity 8 and the liquid cavity 2 by the diaphragm type check valve, the diaphragm type check valve 9 can enable no matter whether gas medium or liquid medium flows towards one direction but can not flow backwards, when a medical worker presses the pressing convex membrane 3, the liquid cavity is compressed and deformed, air enters the filtrate cavity 8 from the liquid cavity 2 to enable the gastric juice to flow towards the stomach, the liquid cavity recovers the original shape after the pressing convex membrane is loosened, the backflow gastric juice can be returned into the digestive system by repeatedly pressing the pressing convex membrane, and unnecessary medical accidents are avoided,
the above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
