[0006] Preferably, the lower outer walls of the instrument main case and the working case are kept flush, the upper front corners of the instrument main case and the working case are both curved, and the detachable maintenance panel is fixedly connected to the instrument main case by a plurality of embedded buckles.

After the box door A and the box door B are closed, the front outer wall is flush with the front outer wall of the working chassis.

[0008] Preferably, the instrument main case and working case are fixedly connected to the bottom placement foot cups by screws, and the multiple placement foot cups can be individually adjusted to five centimeters in height, and anti-slip pads are provided on the lower end outer walls of the multiple placement foot cups.

[0012] Preferably, the steps of the method of use are as follows:

[0013] Step 1: First, the full-spectrum flow cytometer needs to be moved to the location where it needs to be used. Then, the multiple foot cups at the bottom of the instrument main case and the working case need to be used to place the full-spectrum flow cytometer on the ground or table. Then, the height of the multiple foot cups can be adjusted according to the use requirements. By changing the height of the foot cups, the use height of the entire full-spectrum flow cytometer can be changed, so that the full-spectrum flow cytometer can be used at the optimal height.

[0014] Step 2: Then it is necessary to connect the power supply to the instrument main case and the working case of the full-spectrum flow cytometer, and at the same time, it is necessary to connect the full-spectrum flow cytometer to the external control terminal through multiple external connectors on the instrument main case, so that the full-spectrum flow cytometer can transmit the detection structure to the terminal in real time, and then the box door A and the box door B can be opened, and the sample to be tested can be placed inside the working case, and then the box door A and the box door B can be closed again, and then the full-spectrum flow cytometer can be started normally;

[0015] Step 3: The cells to be tested, stained with a specific fluorescent dye, are placed in a sample tube. Under the pressure of gas, the cells enter a flow chamber filled with sheath fluid. Under the constraint of the sheath fluid, the cells are arranged in a single file and ejected from the nozzle of the flow chamber to form a cell column. The scattered light signal and fluorescence signal are excited by the laser. The signals are collected by respective laser detectors, amplified by photomultiplier tubes (PMTs), converted into electrical signals, and analyzed by a computer system.

[0016] Compared with the prior art, the present invention provides a full-spectrum flow cytometer and a method of using the same, which have the following beneficial effects:

[0017] 1. The present invention adds a novel small distance adjustment device to the bottom of the full-spectrum flow cytometer. When not in use, the novel small distance adjustment device can be adjusted to a storage state through the adjustment mechanism, which will not affect the normal placement and use of the entire full-spectrum flow cytometer through multiple placement foot cups. When the use position of the full-spectrum flow cytometer needs to be fine-tuned, the small distance adjustment device can be adjusted to a displacement function state through two adjustment mechanisms. In this way, the full-spectrum flow cytometer can be displaced and adjusted on a desktop or the ground through the displacement function of the small distance adjustment device. Especially when the full-spectrum flow cytometer is placed for the first time, the placement position of the full-spectrum flow cytometer can be adjusted by the small distance adjustment device so that it can be used in the optimal placement state, thereby greatly increasing the practicality and flexibility of use of the full-spectrum flow cytometer, avoiding the situation where the instrument is easily damaged by simply carrying it manually when adjusting the placement angle of the full-spectrum flow cytometer, and thus avoiding unnecessary economic losses.

[0018] 2. When the small distance adjustment device of the present invention is in the storage state, the upper outer wall of the support plate is in contact with the bottom outer wall of the instrument main case and the working case of the full-spectrum flow cytometer, and the lower outer wall of the support plate is not in contact with the placement ground or desktop, thereby ensuring that the full-spectrum flow cytometer can be placed and used normally through multiple placement foot cups. When it is necessary to adjust the displacement of the placed full-spectrum flow cytometer, the displacement function of the small distance adjustment device is needed to assist the full-spectrum flow cytometer in displacement adjustment. During the specific operation, first, you need to grab the operating head at the upper end of the support screw A and turn it clockwise. When the support screw A is turned clockwise, it will slowly descend through the threaded pushing action of the internal threaded adjustment cylinder, so that the support screw will synchronously drive the right end of the support plate to move downward when it descends, until the bottom of the right end of the support plate is in contact with the ground or table. Then, the support screw B is driven to rotate through the operating head in the same way, and when the support screw B descends, it will push the left end of the support plate to move downward until the bottom of the left end of the support plate is also in contact with the ground or table. Because there are multiple ball bearing holes with downward openings inside the support plate, and displacement balls are penetrated downward inside the multiple ball bearing holes, when the support plate is adjusted to the left When the bottoms of both right ends are in contact with the ground or desktop, multiple displacement balls passing through the ball bearing holes are in contact with the ground or desktop, and multiple displacement balls will replace the foot cups to place the full-spectrum flow cytometer. Therefore, the full-spectrum flow cytometer can be directly pushed by the rolling action of the displacement balls. In this way, the placed full-spectrum flow cytometer can be adjusted to a small distance, so that the full-spectrum flow cytometer can be adjusted to the optimal position and angle for use. After adjustment, the support screws A and B need to be rotated counterclockwise to move the support plate upward, which will make the multiple placements The foot cup plays a placement role again to place the full-spectrum flow cytometer. During the above adjustment process, the shaft connecting seat not only connects the support screw A and the angle deflection connector and the support screw B and the angle deflection connector, but also allows the support screw A and the support screw B to rotate independently, which will not cause the support plate to rotate. The two angle deflection connectors, while playing a connecting role, can ensure that the left and right ends of the support plate can rotate downward independently when the support screw A and the support screw B move downward, which will not hinder the adjustment operation of the support plate, thereby increasing the flexibility of use of the small-distance adjustment device.

[0028] Example 2

[0029] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4The present invention provides a technical solution: a full-spectrum flow cytometer and a method for using the same. The small-distance adjustment device 9 includes an operating head 12, a support screw A13, a displacement ball 14, a ball hole 15, a support plate 16, an angle deflection connector 17, a rotating shaft connection seat 18, an internal thread adjustment cylinder 19 and a support screw B20. The support plate 16 is laterally arranged on the outside of the lower outer wall of the instrument main case 1 and the working case 5. The length of the support plate 16 is greater than the sum of the lengths of the instrument main case 1 and the working case 5. After the upper outer wall of the support plate 16 is attached to the lower outer wall of the instrument main case 1 and the working case 5, the lower outer wall of the support plate 16 does not contact the ground or the desktop. Angle deflection connectors 17 are provided on the upper outer walls on both sides of the support plate 16. The upper ends of the two angle deflection connectors 17 are each provided with a rotating shaft connection seat 18, and an internal thread adjustment cylinder 19 is vertically provided on the outer wall of the instrument main case 1 near the lower left end and on the outer wall of the working case 5 near the lower right end. The two internal thread adjustment cylinders 19 are respectively penetrated by a support screw A13 and a support screw B20 vertically. The support screw A13 and the support screw B20 are respectively located on the outside of the outer wall of the left end of the instrument main case 1 and the outside of the outer wall of the right end of the working case 5. The lower ends of the support screw A13 and the support screw B20 are respectively fixedly connected to the two rotating shaft connection seats 18, and the upper ends of the support screw A13 and the support screw B20 are both provided with an operating head 12. The length and diameter of the support screw A13 and the support screw B20 are equal. The threads on the outer wall of the support screw B20 are meshed with the threads on the inner wall of the internal thread adjustment cylinder 19. The cross-sectional shape of the operating head 12 is a regular hexagon. The interior of the support plate 16 is equidistantly provided with a plurality of ball holes 15 with downward openings. The interiors of the plurality of ball holes 15 are penetrated downward by displacement balls 14. The ball holes 15 are three-quarter volume spherical holes. A quarter of the lower end of the displacement ball 14 penetrates the lower end opening of the ball hole 15. The lower ends of the plurality of displacement balls 14 are kept on the same horizontal plane. When operating the small distance adjustment device 9, you first need to grab the operating head 12 at the upper end of the support screw A13 and turn it clockwise. When the support screw A13 rotates clockwise, it will slowly descend through the thread pushing action of the internal thread adjustment cylinder 19. This In this way, when the support screw rod descends, the right end of the support plate 16 will be synchronously driven to move downward until the bottom of the right end of the support plate 16 is in contact with the ground or table. Then, in the same way, the support screw rod B20 is driven to rotate by the operating head 12. When the support screw rod B20 descends, it will push the left end of the support plate 16 to move downward until the bottom of the left end of the support plate 16 is also in contact with the ground or table. Because the support plate 16 has a plurality of ball holes 15 opening downward, and the plurality of ball holes 15 have displacement balls 14 passing through them downward, when the left and right bottom ends of the support plate 16 are in contact with the ground or table after adjustment, the plurality of displacement balls 14 passing through the ball holes 15 are all in contact with the ground or table.The multiple displacement balls 14 replace the foot cups 4 to place the full-spectrum flow cytometer. Therefore, the full-spectrum flow cytometer can be directly pushed by the rolling action of the displacement balls 14. In this way, the placement position of the full-spectrum flow cytometer can be adjusted by a small distance, so that the full-spectrum flow cytometer can be adjusted to the optimal position and angle for use.

[0030] The working principle and use process of the present invention: After the present invention is installed, when using the full-spectrum flow cytometer, first, the full-spectrum flow cytometer needs to be moved to the position where it needs to be used, and then the multiple placement feet 4 at the bottom of the instrument main case 1 and the working case 5 need to be placed on the ground or table where the full-spectrum flow cytometer needs to be used, and then the use height of the multiple placement feet 4 can be adjusted according to the use requirements. By changing the height of the placement feet 4, the use height of the entire full-spectrum flow cytometer can be changed, so that the full-spectrum flow cytometer can be used at the optimal height, and then the instrument main case 1 and the working case 5 of the full-spectrum flow cytometer need to be powered on, and at the same time, the full-spectrum flow cytometer needs to be placed on the ground or table through the multiple external connectors 2 on the instrument main case 1. The cytometer is connected to the external control terminal so that the full-spectrum flow cytometer can transmit the detection structure to the terminal in real time. Then the box door A6 and the box door B7 can be opened, and the sample to be tested is placed inside the working chassis 5. Then the box door A6 and the box door B7 are closed again, and then the full-spectrum flow cytometer can be started normally. During the detection, the cells to be tested after being stained with specific fluorescent dyes are placed in the sample tube. The cells enter the flow chamber filled with sheath fluid under the pressure of the gas. Under the constraint of the sheath fluid, the cells are arranged in a single row and ejected from the nozzle of the flow chamber to form a cell column. The scattered light signal and the fluorescence signal are excited by the laser, and the signals are collected by their respective laser detectors. The signals are then amplified by the photomultiplier tube (PMT), converted into electrical signals, and analyzed by the computer system.

Under the constraint of the sheath fluid, the cells are arranged in a single row and ejected from the nozzle of the flow chamber to form a cell column. The scattered light signal and the fluorescence signal are excited by the laser, and the signals are collected by their respective laser detectors. The signals are then amplified by a photomultiplier tube (PMT), converted into electrical signals, and analyzed by a computer system.
