[0020] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples.
[0021] As shown in Figures 1-4 A liquid medicine sampling device, comprising a round rod 1, a spandex rope 10 is fixedly connected to the lower end of the round rod 1, a floating ball 7 is fixedly connected to the upper side of the spandex rope 10, and three sampling mechanisms are installed on the outer side of the spandex rope 10.
[0022] In use, the user will put the round rod 1 into the inside of the liquid medicine tank, at this time the floating ball 7 will float on the surface of the liquid medicine by its own characteristic that the density is less than the density of the liquid medicine, it mainly has two effects, one is to make the spandex rope 10 in a straight state through the buoyancy, to ensure that the sampling mechanism on the spandex rope 10 can be distributed in the liquid medicine according to the predetermined position;
[0023] The second is that it can float up and down with the fluctuation of the liquid level of the liquid medicine, to ensure that the sampling mechanism is always in the appropriate sampling position and is not affected by the change of the liquid level;
[0024] At this time, the three sampling mechanisms located at the upper, middle and lower of the liquid medicine will be at different height positions of the liquid medicine, so that the different depth layers of the liquid medicine can be sampled to obtain more comprehensive information of the liquid medicine sample, avoiding the deviation that may be caused by taking a single depth sample;
[0025] One, the upper surface layer of the liquid medicine may be in contact with air, and is easy to be affected by oxidation, volatilization and other factors, its composition and properties may be different from other layers; two, the middle layer is usually considered as the main part of the liquid medicine, its composition and properties are relatively stable and uniform, and can represent the main characteristics of the liquid medicine; three, the lower layer is mainly used for detecting whether there are impurities such as precipitate and crystal in the lower layer of the liquid medicine, and their content and properties. Through the sampling analysis of the lower layer of the liquid medicine, the stability of the liquid medicine can be understood, whether there are problems such as degradation and precipitation of drug components can be judged, and the quality change of the liquid medicine in the long-term storage process can be evaluated.
[0026] As shown in Figure 1 , the sampling mechanism includes a sampling bin 8 installed outside the spandex rope 10, the sampling bin 8 is a hollow structure, a circular hole is formed on one side of the sampling bin 8, and an electric one-way valve 9 is fixedly connected in the circular hole. In use, when the device reaches the predetermined sampling depth, the electric one-way valve 9 is opened, the liquid medicine flows into the sampling bin 8 through the electric one-way valve 9, and for different layers of the sampling mechanism, the liquid medicine at the corresponding depth is collected at this time. When the sampling is completed, the electric one-way valve 9 is closed, which can prevent the liquid medicine in the sampling bin 8 from flowing back to the liquid medicine tank, to ensure that the sampled liquid sample is completely saved in the sampling bin 8, so as to be taken out for subsequent detection and analysis.
[0027] As shown in Figure 1 , Figure 2 , Figure 3 , three spring buckles 11 are installed on the spandex rope 10, one end of the spring buckle 11 is fixedly connected with one end of the sampling bin 8. In use, the spring buckle 11 adjusts the distance between the sampling bins 8, according to different liquid characteristics, tank shapes or sampling requirements, the position of the spring buckle 11 on the spandex rope 10 can be moved to change the distance between the sampling bins 8, so as to better adapt to the actual situation and obtain more representative liquid samples.
[0028] As shown in Figure 1 ,Figure 4 As shown in the figure, the circular rod 1 is provided with a sliding groove 3, and the connecting plate 4 is slidably connected in the sliding groove 3. The end of the connecting plate 4 away from the sliding groove 3 is fixedly connected with one side of the floating ball 7. When in use, the connecting mode of the connecting plate 4 and the sliding groove 3 can limit the swing range of the floating ball 7 and the sampling mechanism, so that the device can maintain a relatively stable posture in the liquid medicine. Meanwhile, when the liquid medicine flows or the device is disturbed by external force, the floating ball 7 and the sampling mechanism will not shake or rotate at will, but will maintain a relatively fixed position and direction under the constraint of the sliding groove 3 and the connecting plate 4, which is beneficial to improve the accuracy and reliability of sampling.
[0029] As shown in the figure, Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting plate 4 is fixedly connected with the bracket 5 on the outer side, the bracket 5 is provided with a threaded hole, and the threaded hole is threadedly connected with the screw 6. One end of the screw 6 abuts against the end face of the circular rod 1. When in use, after being adjusted to the appropriate depth, the screw 6 is tightened, the end of the screw 6 abuts against the end face of the circular rod 1, and the screw 6 tightly fixes the bracket 5 and the connecting plate 4 on the circular rod 1, so that the connecting plate 4 cannot slide in the sliding groove 3 any more, and the position of the floating ball 7 and the sampling mechanism is fixed, thereby ensuring that the device can maintain at the set depth during sampling, and accurately sampling the liquid medicine at the corresponding depth.
[0030] As shown in the figure, Figure 1 , Figure 4 The circular rod 1 is sleeved with the anti-skid sleeve 12 on the outer side. The anti-skid sleeve 12 is made of rubber. When in use, when the user holds the anti-skid sleeve 12, the rubber surface of the anti-skid sleeve 12 generates friction with the skin or gloves of the hands, reduces the relative sliding between the hands and the anti-skid sleeve 12, and increases the stability of the user in holding the circular rod 1.
[0031] As shown in the figure, Figure 1 , Figure 4 The circular rod 1 is fixedly connected with the cross rectangular block 2 at the lower end. When in use, when the device is placed in the liquid medicine tank, the cross rectangular block 2 can be in contact with the bottom of the medicine tank, and additional supporting force is provided, so that the device is more stable in the liquid medicine tank and is not easy to incline or shake, the stability of the device is increased, and the accuracy of sampling is prevented from being affected by the shaking of the device.
[0032] The working principle of the device is as follows: when in use, the user places the circular rod 1 into the liquid medicine tank. At this time, the floating ball 7 floats on the surface of the liquid medicine by virtue of the characteristic that the density of the floating ball 7 is less than the density of the liquid medicine. The floating ball 7 mainly has two effects: one is that the spandex rope 10 is in a straightened state through the buoyancy, so that the sampling mechanism on the spandex rope 10 can be distributed in the liquid medicine according to the predetermined position;
[0033] Second, it can float up and down with the fluctuation of the liquid level, ensure that the sampling mechanism is always in the appropriate sampling position, not affected by the liquid level change;
[0034] At that time, the three sampling machines at the upper, middle and lower of the liquid will be at different height positions of the liquid, so that the different depth layers of the liquid can be sampled to obtain more comprehensive liquid sample information, and avoid the deviation caused by only taking a single depth sample.
[0035] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application are implemented according to the conventional means in the art, unless otherwise specified and limited.
