SPECIFIC EMBODIMENTS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative pulls are within the scope of protection of the utility model.

[0031] Embodiment 1: This embodiment Figures 1 - 3 As shown, in order to solve the problem that the sampler is prone to over-sampling or under-sampling, the positioning process of the proton pump inhibitor quantitative sampler is disclosed, and the effect of the sampler avoiding sampling deviation is achieved. The specific contents are as follows:

[0032] An instrument body 1 and a sealing plate 2 fixedly mounted on the upper end of the instrument body 1;

[0033] A fixed cylinder 3 is fixedly installed inside the sealing plate 2, and the internal thread of the fixed cylinder 3 is connected to the limiting cylinder 4, and a rotating rod 5 is fixedly installed at an equal angle on the outer side of the upper end of the limiting cylinder 4, a driving rod 6 is slidably installed inside the limiting cylinder 4, and a sealing rubber block 7 is sleeved on the outer side of the lower end of the driving rod 6, and the sealing rubber block 7 is slidably connected to the inner surface of the instrument body 1.

[0034] When using the proton pump inhibitor quantitative sampler, first place the sampler at the position where it needs to work. After placing the sampler at the required position, the sampler can sample the proton pump inhibitor. Before sampling, the limiting cylinder 4 needs to be adjusted to the required position according to the scale line on the outside of the instrument body 1. In this process, the limiting cylinder 4 needs to be driven by the rotating rod 5 to rotate. During the rotation of the limiting cylinder 4, it will move up and down inside the fixed cylinder 3, thereby changing the position of the limiting cylinder 4. The instrument body 1 is made of transparent material, and the position of the limiting cylinder 4 can be intuitively observed. During the movement of the limiting cylinder 4, the driving rod 6 will drive the sealing block 7 to move, so that the sealing block 7 moves up and down with the limiting cylinder 4. After that, the sealing block 7 can be moved to the initial position. At this time, the driving rod 6 can be pulled to drive the sealing block 7 for sampling. After the sealing block 7 contacts the limiting cylinder 4, the driving rod 6 can be stopped. At this time, the proton pump inhibitor inside the sampler can be the required dose, thereby effectively improving the accuracy of the use of the sampler.

[0035] Embodiment 2: This embodiment is as follows Figure 1 and Figure 6 As shown, in order to solve the problem that bubbles are generated inside the sampler when it is quickly extracted and affect the sampling effect, the working process of the control structure of the proton pump inhibitor quantitative sampler is disclosed, and the sampling result of the sampler is highly accurate. The specific contents are as follows:

[0036] Inside the main body 1 of the instrument, a control structure is provided, and the control structure realizes the accuracy of sampling of the main body 1 of the instrument through the principle of pressure.

[0037] Inside the control structure, an exhaust hole 8 and a ventilation hole 9 are provided. The exhaust hole 8 and the ventilation hole 9 are opened at equal angles inside the sealing plate 2, and both the exhaust hole 8 and the ventilation hole 9 are provided with four groups, and the radius dimension of the ventilation hole 9 is larger than the radius dimension of the exhaust hole 8.

[0038] Inside the control structure, a mounting member 10 and a sliding rod 11 are provided. The mounting member 10 is fixedly installed on the inner surface of the main body 1 of the instrument, and the sliding rod 11 is slidably installed inside the mounting member 10. A support spring 12 is sleeved on the outer side of the sliding rod 11, and a sealing member 13 is fixedly installed at the upper end of the sliding rod 11.

[0039] A sealing ring 14 is sleeved on the outer side of the sealing member 13, and the sealing member 13 is in an isosceles trapezoid structure when viewed from the front, and the sealing member 13 and the ventilation hole 9 form a sealing structure through the sealing ring 14.

[0040] After the position adjustment of the limit cylinder 4 is completed, the sealing rubber block 7 needs to be adjusted to the initial position, and then the sealing rubber block 7 is pulled by the driving rod 6 to complete the sampling of the proton pump inhibitor. During the process of adjusting the sealing rubber block 7 to the initial position, the control rod 15 needs to be pushed to move inside the driving rod 6. During the movement of the control rod 15, the two sets of sliding members 17 will be driven to move closer to each other through the two sets of connecting ropes 19. During the process of the sliding members 17 moving closer to each other, the clamping block 20 will be separated from the clamping groove 21, and the connecting spring 16 will be compressed by the control rod 15 and contract. After the clamping block 20 is separated from the clamping groove 21, the driving rod 6 can be pushed to move and drive the sealing rubber block 7 to move to the initial position. Then, when extracting the proton pump inhibitor, the control rod 15 also needs to be pressed. After the clamping block 20 is separated from the clamping groove 21, the sampling work can be carried out. After the sampling is completed, the control rod 15 is released, and the two magnetic plates 18 will repel each other and push the clamping block 20 to be engaged with the clamping groove 21 again, and the connecting spring 16 will expand and push the control rod 15 to move to the initial position, thus preventing the proton pump inhibitor inside the sampling instrument from overflowing due to accidental touch after sampling, effectively ensuring the stability of the use of the sampling instrument.

[0041] Example 3: As shown in this example Figures 1 - 5 In order to solve the problem that air bubbles will appear during the sampling process of the sampling instrument, the sampling process of the proton pump inhibitor quantitative sampling instrument is disclosed, realizing the effect of avoiding air bubbles inside the sampling instrument. The specific content is as follows:

[0042] The inside of the driving rod 6 is provided with a limiting structure, and the limiting structure can achieve the effect of stable use of the driving rod 6 through the engagement principle;

[0043] The inside of the limiting structure is provided with a connecting spring 16 and a sliding member 17. The connecting spring 16 is fixedly installed at one end of the control rod 15 close to the sealing rubber block 7. The sliding member 17 is slidably installed inside the driving rod 6, and a magnetic plate 18 is fixedly installed at one end of the sliding member 17 close to the control rod 15;

[0044] A connecting rope 19 is fixedly installed at one end of the sliding member 17 close to the control rod 15, and two groups of the connecting rope 19, the sliding member 17 and the magnetic plate 18 are symmetrically arranged about the vertical central axis of the control rod 15;

[0045] A clamping block 20 is fixedly installed at one end of the sliding member 17 away from the magnetic plate 18. Card slots 21 are equidistantly formed on the inner surface of the limiting cylinder 4, and the clamping block 20 is located inside the card slots 21.

[0046] When using this proton pump inhibitor quantitative sampler, the lower end of the instrument main body 1 can be placed inside the proton pump inhibitor, and then the driving rod 6 can be pulled to drive the sealing rubber block 7 to move upward. During this process, the gas between the sealing rubber block 7 and the sealing plate 2 will slowly discharge through the exhaust hole 8, so that the movement of the sealing rubber block 7 is slow, avoiding bubbles caused by the rapid movement of the sealing rubber block 7 and affecting the sampling accuracy. During the discharging process of the sampler, the driving rod 6 can be pushed to drive the sealing rubber block 7 to move rapidly. At this time, the pressure between the sealing plate 2 and the sealing rubber block 7 will be less than the external air pressure, and the sealing member 13 will separate from the ventilation hole 9, and the external air will enter between the sealing plate 2 and the sealing rubber block 7 through the ventilation hole 9. During the movement of the sealing member 13, the connecting spring 16 will be squeezed and the connecting spring 16 will contract, so as to facilitate the rapid discharge of the proton pump inhibitor inside the sampler, effectively ensuring the accuracy and convenience of the use of the sampler and increasing the overall practicability.
