Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nuclear magnetic tube cleaning device. Background Art

[0002] NMR tubes are essential tools for measuring NMR spectra in the laboratory. NMR spectra are affected by various factors, among which NMR tubes are one of the influencing factors. Incomplete cleaning of NMR tubes, improper cleaning methods, or cracks or damage to the NMR tubes will affect the experimental results. The length of the NMR tube is about 16cm, the inner diameter is about 5mm, and the tube wall is very thin. Compared with ordinary test tubes, NMR tubes are difficult to clean and are very easy to break during cleaning and use.

[0003] The traditional cleaning methods for NMR tubes are manual cleaning or ultrasonic cleaning. Manual cleaning, that is, directly inserting a cotton swab with cleaning fluid into the NMR tube for cleaning or using the "shaking method" for cleaning, has the advantage of relatively clean cleaning, but it takes a long time and it is very easy to scratch the NMR tube during the cleaning process. When the ultrasonic cleaning device is used to clean the NMR tube, its advantage is fast cleaning speed, but the cleaning quality is poor, and ultrasonic cleaning is very likely to cause the NMR tube to break or crack.

[0004] In addition to the above traditional cleaning methods, there are also NMR tube cleaners currently on the market. NMR tube cleaners can save a lot of time, but they can only clean 5 NMR tubes at the same time and are expensive. Utility Model Content

[0008] A connector, to which a plurality of liquid dispensing tubes are connected, the liquid dispensing tubes penetrate the support plate and communicate with the bottom end of the water outlet bracket;

[0009] A first infusion tube, one end of which is connected to one end of the second infusion tube and then connected to the connector; wherein the other end of the first infusion tube is inserted into the first washing bottle, and the other end of the second infusion tube is inserted into the second washing bottle;

[0010] A waste liquid barrel, in which a waste liquid pipe is inserted, and the waste liquid pipe is connected to the waste liquid outlet;
