[0002] Patients with Alzheimer's disease, dysphagia, coma due to craniocerebral injury, or esophageal tumor compression that prevents them from eating or drinking can have necessary water and food delivered through a gastric tube. Gastric tubes are generally made of silicone and should be replaced once a month to avoid long-term use that may cause gastric tube blockage and bacterial growth. The common method of gastric tube insertion is to insert the tube directly through the nostril about 55 cm, through the pharynx, through the esophagus to the gastric cardia, and then into the patient's stomach.

[0003] However, when replacing a gastric tube in the prior art, the old gastric tube needs to be removed first and then a new one is inserted. The removal and insertion process causes great stimulation to the patient, making the reinsertion process very difficult. Medical staff need to manually control and guide the gastric tube gradually through the esophagus to the stomach, which is very inconvenient. To this end, we provide a bedside X-ray guidance device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a bedside radiation-specific guidance device. Through the setting of the guidance component, the problem of the prior art that the gastric tube has no guidance function when it is replaced, which causes great irritation to the patient, and the gastric tube is easily mistakenly inserted into the trachea when it is pulled out and reset is solved.

Specific embodiment three

[0032] See also Figure 1-4Based on specific embodiments one and two, the length of the guide wire 4 is twice the length of the gastric tube 1, the guide wire 4 is hollow, a second sealing plug 10 is provided inside the air inlet tube 6, the guide wire 4 is made of polyurethane, and the bottom of the second sealing plug 10 is fixedly connected to a fixing belt, and the top of the fixing belt is fixedly connected to the second sealing plug 10.

[0033] Specifically, the scale 7 on the surface of the guide wire 4 can facilitate medical staff to measure the specific insertion length of the gastric tube 1. The length of the guide wire 4 is twice the length of the gastric tube 1, which can facilitate guiding the old gastric tube 1 when the old gastric tube 1 is pulled out. The guide wire 4 is made of polyurethane. The guide wire 4 made of polyurethane has good flexibility and high strength. The second sealing plug 10 is made of rubber and can seal the air inlet pipe 6.

[0034] The working principle of the present invention is as follows: when the old gastric tube 1 remains in the patient's body, the patient's gastric fluid is extracted through the old gastric tube 1 connected to the external needle, the pH value is detected, and it is confirmed that the old gastric tube 1 is in the patient's stomach, and then the guide wire 4 is inserted into the original gastric tube 1, and then the old gastric tube 1 is completely pulled out of the patient's body along the guide wire 4, and the old gastric tube 1 is separated from the guide wire 4, and then the new gastric tube 1 is inserted into the patient's body along the guide wire 4. Figure 4 As shown, the air inlet tube 6 is connected to the external syringe, and gas is injected into the guide wire 4 through the syringe to inflate the air bag 5, thereby blocking the insertion of the new gastric tube 1. The insertion length of the new gastric tube 1 is made the same as that of the old gastric tube 1, ensuring accurate insertion into the patient's stomach.

[0035] After the insertion is completed, the balloon 5 is deflated, and the guide wire 4 is pulled out of the gastric tube 1. Then, the new gastric tube 1 is connected to the external needle again to extract the patient's gastric juice, detect the pH value, and confirm that the new gastric tube 1 is in the patient's stomach.
