Please refer to Fig. 1, Fig. 2 and Fig. 3, an inflatable visual gastric tube inserter, comprising a gastric tube 1, a gastric tube sleeve 3 is sleeved at the position of the mouth of the right end of the gastric tube 1, and the gastric tube The middle part of the left side of the tube sleeve 3 is fixedly connected with a gastric tube plug 31, and the mouth of the right end of the gastric tube 1 is movably connected with an insertion tube 4, and a through hole 41 is opened at the central position on the right side of the front view of the inserted tube 4, The through hole 41 extends to the position of the visual probe 43, and the other end of the guide wire 42 is fixedly connected to the body of the visual probe 43 after passing through the through hole 41. A guide wire 42 runs through the through hole 41. A visual window 5 is fixedly connected to one end, a handle 51 is fixedly connected to the middle part of the right side of the visual window 5, and a visual probe 43 is fixedly connected to the left end of the insertion tube 4. The visual probe 43, the guide wire 42 and the visual window 5 are all optional. Reusable consumables, the design can better enable medical staff to observe the process of placement, and at the same time achieve the effect of reuse and save resources.

Please refer to FIG. 2 and FIG. 3 , an inflatable sleeve 2 is sleeved on the outer surface of the insertion tube 4, the inflatable sleeve 2 is in a sealed state, and the left end of the inflatable sleeve 2 extends to a position close to the visible probe 43, The left end of the inflatable sleeve 2 is annularly sleeved with a snap ring 22, the left end opening of the gastric tube 1 is an arc-shaped opening, and the specific performance is that the left side is narrower and the right side is the same as the diameter of the gastric tube 1, and the snap ring 22 is. A glue-packed ring body, the snap ring 22 closely fits with the inner wall of the gastric tube 1, the diameter of the snap ring 22 is larger than the opening at the left end of the gastric tube 1, and this design can ensure that the snap ring 22 is better in the The inner wall of the stomach tube 1 slides without protruding from the left end of the stomach tube 1, the left side of the right end of the inflatable sleeve 2 is provided with a perforation, and the inflatable tube 21 is penetrated and fixedly connected in the perforation. The connection position is coated with a layer of medical adhesive, which can ensure the sealing of the connection position.

Please refer to FIGS. 1 , 2 and 3 , the volume of the visible probe 43 is smaller than the volume of the snap ring 22 , and the diameter of the visible probe 43 is smaller than the diameter of the opening at the left end of the gastric tube 1 . This design can ensure that the Depending on the probe 43 will not protrude from the left end of the gastric tube 1, the inflatable sleeve 2 is a transparent sleeve-shaped body, and the inflatable tube 21 and the insertion tube 4 are both small transparent silicone hoses, and this design can be better. It is convenient for medical staff to observe.

Working principle: When the patient needs to insert the gastric tube, the medical staff first inserts the lubricated gastric tube 1 into the patient's throat through one nostril, and then inserts the insertion tube 4 into the gastric tube through the gastric tube sleeve 3. In the tube body of 1, since the outer surface of the tube of the insertion tube 4 is sleeved with the inflatable sleeve 2, the inflatable sleeve 2 also enters the tube body of the gastric tube 1 with the insertion tube 4, and then the switch of the inflatable tube 21 is turned on, so that The inflatable tube 21 evenly inflates the inflatable sleeve 2. After the inflatable tube 21 is closely attached to the inner wall of the gastric tube 1, the medical staff then pinches the visual window 5 with the right hand, and holds the gastric tube 1 with the left hand. By observing the images brought by the visual window 5 and the visual probe 43, the personnel can make relevant adjustments to the gastric tube 1 so that the gastric tube 1 can smoothly enter the esophagus entrance and be inserted slowly. The inflatable tube 21 can be deflated, so that the gas in the inflatable sleeve 2 is discharged through the inflatable tube 21, and then slowly withdrawn from the insertion tube 4. After the insertion tube 4 is withdrawn, the gastric tube 1 is continued to be inserted into the patient's stomach. .

To sum up, the inflatable visual gastric tube implanter passes through the inflatable sleeve 2, the inflatable tube 21, the snap ring 22, the insertion tube 4, the through hole 41, the guide wire 42, the visual probe 43 and the visual window The design of 5 effectively realizes that when the device is used on a patient, an accurate judgment can be made on the implantation situation. At the same time, the medical staff can effectively avoid contact with the patient during implantation by observing the visual window 5. The mucous membrane of the throat is in contact, thereby reducing the pain of the patient. At the same time, the patient can also reduce his own fear and resistance to the gastric tube 1 by observing the visual window 5. The requirements for understanding and cooperating strength are reduced, and the gastric tube 1 can be reused after being sterilized, thereby avoiding the waste of equipment.
