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.
Examples
Referring to fig. 1, the gastric tube of the present invention capable of being accurately positioned includes: the stomach tube comprises a stomach tube body 100, wherein the front end of the stomach tube body 100 is provided with a balloon 140, the inner side wall of the stomach tube body 100 is provided with an inflation conduit 141, and the inflation conduit 141 is communicated with the balloon 140. The balloon 140 is provided on the gastric tube body 100, so that the gastric tube can be positioned and fixed, and the gastric tube can be prevented from falling off. The balloon 140 can be inflated through the inflation catheter 141 so as to be expanded, thereby realizing the positioning and fixing of the gastric tube body 100 and further preventing the falling-off of the gastric tube body 100. In an embodiment, the distance L between the balloon 140 and the top surface of the insertion end of the gastric tube body 100 is 10-15 cm. In this way, since the stomach tube body 100 is inserted by about 50cm, the balloon 140 is also inserted into the stomach, and after the balloon 140 is inflated, the stomach tube body 100 can be prevented from being pulled out due to the obstruction of the cardia. The outer wall of the gastric tube body 100 is provided with graduation marks (not shown in the figure). The position of stomach tube implantation can be generally calculated through the scale marks, and whether the stomach tube is inserted into the stomach or not is preliminarily predicted and judged.
The guide wire 110 is threaded in the cavity of the gastric tube body 100, and the guide wire 110 is a traditional aluminum rod and plays a role in supporting and shaping. The guide wire 110 extends to the front opening of the stomach tube body 100 along the length direction of the stomach tube body 100;
the hollow cavity of the guide wire 110 is provided with a capillary 120 along the extending direction, the inner cavity of the capillary 120 is provided with a test wire 130 twisted by pH test paper, in this embodiment, the diameter of the test wire 130 is 0.5-2 mm. A foam water absorption ball 121 is arranged at the opening of the capillary pipette 120 close to the guide wire 110, and the foam water absorption ball 121 is connected and contacted with the test wire 130. In this embodiment, the non-toxic and safe foam absorbent ball 121 is used to impregnate the gastric acid, and then the gastric acid is transferred to the test line 130 in the capillary pipette 120, so that the test line 130 is prevented from directly contacting the gastric acid, and the test line 130 is ensured not to have bad influence on the body in the detection process.
The end of the capillary pipette 120 far away from the foam water absorption ball 121 is 1-2cm longer than the end of the guide wire 110 far away from the foam water absorption ball 121, and the length of the capillary pipette 120 is consistent with that of the test wire 130. By the arrangement, whether accurate positioning is achieved can be determined by judging whether the test wire 130 in the capillary pipette 120 changes color or not under the condition that the guide wire 110 is not pulled out, and the positioning is simpler and quicker. And the length of the guide wire 110 is greater than that of the gastric tube body 100, so that the guide wire 110 can be pulled out at the later stage. The buffer sponge layer 150 is filled between the capillary pipette 120 and the guide wire 110, and the buffer effect of the buffer sponge before the capillary pipette 120 and the guide wire 110 is increased, so that the damage to the capillary pipette 120 in the inner cavity when the guide wire 110 is bent is avoided, and the detection result of the test wire 130 is not influenced.
The working principle of the utility model is as the process
The test line 130 twisted by the pH test paper can accurately reflect the pH value of the gastric juice, the pH value of the gastric juice is between 0.9 and 1.5, the gastric juice is strongly acidic, and the color detected by the test line 130 is orange; the acid-base strength of the esophagus is more than 5, the esophagus is weakly acidic, and the color detected by the corresponding test line 130 is light yellow; the gas line has a small amount of lubricating fluid, which is generally neutral and green in color corresponding to the color detected by test line 130. After the tube is placed from the nasal feeding, if correctly placed in the stomach, the color of the test wire 130 in the capillary pipette 120 is observed to change to orange without pulling out the withdrawal guidewire 110; and green if mistakenly entered into the trachea. The process can enable the nursing staff to objectively and accurately judge the accuracy of stomach tube placement. After the test line 130 is judged to be orange, the gastric tube placement is accurately positioned, and then the guide wire 110 and the capillary suction tube 120 are pulled out together.
When the stomach tube body 100 is used, the stomach tube body 100 is placed in the stomach of a patient, the gastric juice is acidic, the positioning is accurate after the test line 130 is detected to be orange, and the guide wire 110 is drawn out, so that the problem that when a nursing staff inserts the stomach tube into the stomach of the patient, the nursing staff needs to judge whether the position of the stomach tube is correct through a complex method, the workload of medical staff is increased to a certain extent, and the first-aid time is delayed is solved.
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.
