AI Technical Summary
In the prior art, when loading a nuclear magnet, the sample is prone to spill out due to the small inner diameter of the tube, and the large liquid viscosity leads to sample residue. It needs to be repeatedly oscillated to flow into the bottom, affecting the shim speed, and may generate bubbles, affecting the experimental results. At the same time, the existing gun head cannot reach the bottom of the nuclear magnet, making sampling and storage difficult.
A gun tip device for nuclear magnets is designed, including a gun tip and a hose that is fixedly connected to each other. The hose can be inserted directly to the bottom of the nuclear magnet to achieve sample loading or sampling from the bottom. The hose and the gun tip are removably connected to each other and can be bent freely, and the gun tip is in a conical shape.
Through the setting of the hose, the problem of liquid wall hanging and bubbles is solved, the sample loading process is simplified, the sample accuracy and experimental reliability are improved, and the sample sampling and storage are facilitated.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a gun head device for a nuclear magnetic resonance tube. Background Art
[0002] The NMR tube is a long and thin tube with a length of about 16cm and an inner diameter of only 5mm, which requires great precision when adding samples. At present, researchers use a pipette equipped with a universal gun tip to add the liquid to be tested to the top of the NMR tube, so that the liquid flows down the wall of the NMR tube. However, because the inner diameter of the NMR tube is too narrow, the sample can easily spill out when adding the sample. In addition, because the liquid to be tested has a certain viscosity, the sample liquid often remains on the inner wall of the NMR tube. At this time, it is necessary to repeatedly swing the arm and shake it after adding the sample to make it flow to the bottom. This method is not only cumbersome and time-consuming, but also very easy to cause inaccurate sample volume, which will affect the uniform field speed of the NMR to a certain extent. At the same time, this method is also prone to causing bubbles in the sample in the NMR tube, which in turn affects the experimental results.
[0003] In addition, since some NMR test samples need to be retained after the test is completed, and the existing gun tips cannot reach the bottom of the NMR tube, it is difficult to obtain and preserve the samples. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a gun tip device for a nuclear magnetic tube, aiming to overcome the technical problems encountered in the background technology.
[0005] To achieve the above technical objectives, the utility model provides a gun tip device for a nuclear magnetic tube, comprising a gun tip and a hose fixedly connected to each other, wherein the hose can be directly inserted into the bottom of the nuclear magnetic tube to enable the gun tip device to add or take samples from the bottom of the nuclear magnetic tube.
[0006] The utility model is further configured as follows: the hose and the gun head are integrally formed.
[0007] The utility model is further configured as follows: the hose is detachably fixedly connected to the gun head via a connector.
[0008] The utility model is further configured that: the hose can be bent freely.
[0009] The utility model is further configured as follows: the gun head is configured in a conical structure.
[0010] In summary, compared with the prior art, the utility model provides a gun head device for a nuclear magnetic tube. Through the setting of a hose, the defects of the sample adding method in the prior art, such as liquid sticking to the wall and easy generation of bubbles, are overcome. At the same time, it is also convenient to take out the sample in the nuclear magnetic tube after the test, thereby improving the reliability and practicality of the technology.
