[0054] Application scenario of an exemplary embodiment:

[0055] like Figures 1 to 10 As shown, for example, when used on Monday, the leakage seat 3 is first connected to the support seat 4, and the identification area 55 marked with "Monday" on the support seat 4 is leaked out by rotation, and then the connected leakage seat 3 and the support seat 4 are placed on the bedside table on the side of the bedside. The support seat 4 increases the friction between it and the bedside table through the anti-slip pad 72, which can prevent the nasogastric needle tube placement device from shaking or shifting. After that, the support sleeve 1 is placed on the leakage seat 3, and the support sleeve 1 and the leakage seat 3 are detachably connected by magnetic connection. Then a new syringe is inserted into the accommodating chamber 11 of the support sleeve 1, and the limiting wing on the syringe body is located at the top of the support sleeve 1, and finally the dust cover 2 is set at the top of the support sleeve 1, the piston handle of the syringe is located in the accommodating groove 21, and the limiting wing on the syringe body is located in the accommodating sub-groove 22. The dust cover 2 and the support sleeve 1 are detachably connected by magnetic connection.

[0056] When replacing a new syringe on Tuesday, the dust cover 2 is removed, the used syringe is taken out, and a new syringe is inserted into the accommodating cavity 11, and the dust cover 2 is placed on the top of the supporting sleeve 1. After that, the supporting seat 4 is rotated, and the marking area 55 marked with "Tuesday" is leaked out. The leakage seat 3 and the supporting seat 4 are connected magnetically, so that the supporting seat 4 can be accurately positioned after the rotation of the supporting seat 4.

[0057] When the nasogastric needle tube placement device needs to be cleaned and disinfected, it is only necessary to separate the dust cover 2, the support sleeve 1, and the connected leakage seat 3 from the support seat 4 for cleaning and disinfection. At the same time, there is no need to separate the leakage seat 3 from the support seat 4. It is only necessary to clean and disinfect the liquid accumulation cavity 31 of the leakage seat 3. Taking the disinfection operation as an example, the disinfectant disinfects the liquid accumulation cavity 31, and the disinfectant flows into the gap 54 between the support seat 4 and the leakage seat 3 through the leakage hole 32, and then flows out from the gap 54.
