Description

Technical Field

[0001] This utility model relates to an equal-volume sampling device for medical testing, specifically belonging to the field of medical equipment technology. Background Technology

[0002] Sampling is used to check whether the quality of the sample meets the requirements. Ordinary sampling devices usually consist of a glass pipette and a liquid-absorbing air bag.

[0003] Publication number "CN214200805U" discloses a medical testing equal-volume sampling device, comprising a cylinder, a positioning ring fixedly connected to the inner wall of the cylinder, a fixing ring fixedly connected to the top surface of the cylinder, a large sealing plug slidably connected to the inner wall of the cylinder, a round rod fixedly connected to the upper surface of the large sealing plug, and a disc fixedly connected to the top end of the round rod. This medical testing equal-volume sampling device, by setting up a cylinder, positioning ring, fixing ring, large sealing plug, round rod, and disc, allows sampling through the cylinder. The inclusion of a small sealing plug, connecting rod, control disc, and locking groove facilitates micro-sampling inside the round rod, simplifying subsequent use.

[0004] However, the above technical solution can only perform micro-sampling of one type of sample. If the samples need to be mixed for testing, it is not conducive to improving the efficiency of the device. Moreover, when only one sample is taken, the amount of sample can only be observed by eye. Prolonged observation will cause eye fatigue and put a burden on medical staff. Utility Model Content

[0005] The purpose of this invention is to provide an equal-volume sampling device for medical testing, which improves the efficiency of sample collection and eliminates the need for constant monitoring of sample quantity, thereby reducing the burden on medical staff.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: the new model includes a device shell and a base plate, and also includes a sampling tube, an adjustment component and a component component;

[0007] A base plate is fixedly installed on the bottom surface of the device housing. A drive motor is fixedly installed on the top surface of the base plate by bolts. The drive motor is located between the device housing and the base plate. The output shaft of the drive motor is inserted into the device housing. An adjustment component and a component component are provided inside the device housing. The component component is connected to the output shaft of the drive motor. The adjustment component is located above the component component. A sampling tube is fixedly installed inside the side wall of the device housing.

[0008] Furthermore, the component component can be rotated by the drive motor, which makes the use of the component component more stable. By adjusting the component component and cooperating with it, the same amount of sample can be discharged.

[0009] The adjustment assembly includes a threaded rod, a limiting rod, a slider, a telescopic air rod, and a pressing block; the threaded rod is inserted into the outer shell of the device from the outside to the inside, one end of the threaded rod is inserted into a slot opened in the inner side wall of the device shell, the outer side of the threaded rod is connected to the slider, the inner side of the slider is installed with a limiting rod, the limiting rod is fixedly installed in the inner side wall of the device shell, the front side wall of the slider is fixedly installed with a telescopic air rod, and the output shaft end of the telescopic air rod is fixedly connected to a pressing block;

[0010] Furthermore, the threaded connection between the threaded rod and the slider allows the threaded rod to move the slider horizontally. The limiting rod makes the movement of the slider more stable, preventing the slider from rotating with the threaded rod. The telescopic air rod can move the pressing block vertically, which is beneficial for the subsequent sampling operation of the sample.

[0011] The component assembly includes a component platform, a stirring rod, a slide rod, and a spring; the stirring rod is fixedly installed on the outside of the output shaft of the drive motor, and the component platform is fixedly connected to the end of the output shaft of the drive motor. Two sets of component slots with different capacities are symmetrically opened on the inside of the component platform. A slide rod is installed in the component slot. A spring is installed between the two ends of the slide rod and the component platform. The inner diameter of the component slot is the same as the diameter of the pressing block.

[0012] Furthermore, the drive motor can drive the stirring rod to stir the sample, thereby enabling the device to perform mixed sample testing. Mixed testing can improve the efficiency of the device, reduce costs, save resources, enhance detection capabilities, and reduce the burden on individuals. The sample is divided into portions by two sets of fractionation tanks with different capacities, which facilitates subsequent equal-volume sampling operations. The spring's reset action allows the slide bar to be operated repeatedly.

[0013] A sampling tube is fixedly installed on the side wall of the device casing. The sampling tube is set for the corresponding component platform and is set in an inverted "F" shape.

[0014] Furthermore, the same amount of sample can be taken using a sampling tube.

[0015] A drainage pump is fixedly installed on one side of the device casing. One end of the drainage pump is connected to a connecting hose, and the other end of the connecting hose is connected to an output pipe. The output pipe is fixedly installed inside the device casing, and five sets of spray heads are fixedly connected at equal intervals on one side of the output pipe.

[0016] Furthermore, a drainage pump allows the sample to flow through five sets of spray heads into the fractionation tank of the fractionation platform, thereby enabling the fractionation platform to perform equal-volume fractionation operations.

[0017] A feed funnel is fixedly connected to the front side wall of the device housing, and an observation window is provided on the front side wall of the device housing.

[0018] Furthermore, the sample can be placed into the feed funnel.

[0019] The beneficial effects of this utility model are:

[0020] 1. The structure of the component platform rotating inside the device housing and having a component groove allows the sample to be divided into equal parts by the component platform, which facilitates repeated testing of the device. The structure of the threaded rod and the slider being threaded together allows the threaded rod to drive the telescopic air rod and the pressing block to move through the slider. The cooperation between the pressing block and the component groove allows the sample to be taken out in equal amounts, which improves the ease of use of the device.

[0021] 2. The structure of the stirring rod and the drain pump enables the device to perform mixed testing of samples. This allows for the simultaneous processing of multiple samples, significantly shortening the overall testing time and improving testing efficiency. The drive motor rotates the stirring rod, further enhancing the mixed testing effect. The drain pump allows the samples to flow through five sets of spray heads into the fractionation tank of the fractionation platform, enabling equal fractionation operations.

[0028] The following will be combined with the appendix Figure 1-5 The technical solutions in the embodiments are described clearly and completely.

[0029] Specific implementation method one: as follows Figure 1-3As shown, the device consists of a housing 1, a base plate 2, two sampling tubes 13, and a feed funnel 18. The base plate 2 is the supporting structure of the entire device. A drive motor 3 is fixedly installed between the housing 1 and the base plate 2 by bolts. The output shaft of the drive motor 3 is inserted into the housing 1 from the outside to the inside. At this time, the output shaft of the drive motor 3 is fixedly connected to the component platform 4. The drive motor 3 can drive the component platform 4 to rotate inside the housing 1, which facilitates the subsequent equal-quantity operation of the component platform 4 on the sample. The sample can be put into the feed funnel 18, which is fixedly connected to the front side wall of the housing 1. Multiple samples can be put into the device at the same time, and the sample can be mixed for testing. Mixed testing can significantly shorten the time of the entire detection process, thereby improving the detection efficiency. Since a stirring rod 5 is fixedly installed on the outside of the output shaft of the drive motor 3, the mixed test sample can be stirred by the stirring rod 5, thereby improving the effect of sample mixed testing.

[0030] A drain pump 14 is fixedly installed on one side of the device housing 1. One end of the drain pump 14 is connected to a connecting hose 15, and the other end of the connecting hose 15 is connected to an output pipe 16. The output pipe 16 is fixedly installed inside the device housing 1. Five sets of spray heads 17 are fixedly connected at equal intervals on one side of the output pipe 16. The drain pump 14, through the connecting hose 15 and the output pipe 16, will drive the sample to flow into the five sets of spray heads 17. Since the five sets of spray heads 17 are located above the fractionation platform 4, and the fractionation platform 4 can be driven by the drive motor 3 to rotate, the sample will be divided into equal amounts in two sets of fractionation slots of different capacities symmetrically opened inside the fractionation platform 4, so as to facilitate the subsequent equal sampling operation of the sample.

[0031] Specific implementation method two: such as Figure 4-5As shown, a threaded rod 6 is inserted into the outer casing 1 from the outside in. One end of the threaded rod 6 is inserted into a slot opened in the inner side wall of the outer casing 1. A slider 8 is threadedly connected to the outer side of the threaded rod 6, and a limit rod 7 is installed on the inner side of the slider 8. When the threaded rod 6 is rotated, the threaded connection between the threaded rod 6 and the slider 8 will cause the slider 8 to move horizontally. The limit rod 7 makes the movement of the slider 8 more stable and prevents the slider 8 from rotating synchronously with the rotation of the threaded rod 6. A telescopic air rod 9 is fixedly installed on the front side wall of the slider 8. A pressing block 10 is fixedly connected to the output shaft end of the telescopic air rod 9. A slide rod 11 is provided in the component groove of the component platform 4. Springs 12 are provided between the two ends of the slide rod 11 and the component platform 4. Therefore, when the slider 8 moves to the left side of the threaded groove on the threaded rod 6, the telescopic air rod 9 can drive the pressing block 10 to press a set of sliding rods 11. At this time, one end of the sliding rod 11 will be separated from the bottom surface of the fractionation platform 4. The sample that has been fractionated will enter the sampling tube 13 fixedly installed on the side wall of the device housing 1. The sample can be sampled through the sampling tube 13. Since the fractionation grooves of the fractionation platform 4 are symmetrically arranged, the sample can be sampled again in equal quantities after the fractionation platform 4 rotates half a revolution, thereby improving the convenience of the device. When the slider 8 moves to the right side of the threaded groove on the threaded rod 6, the telescopic air rod 9 can drive the pressing block 10 to press another set of sliding rods 11, so that the device can perform sample sampling operations of different quantities, thereby reducing the burden on medical staff.
