Description

Technical Field

[0001] The present invention relates to the technical field of urine analysis, and in particular to a urine analysis system with double liquid paths. Background Art

[0002] Urine is analyzed through visual inspection, physics, chemistry, microscope and instruments to achieve the purpose of preventing, diagnosing, observing therapeutic effects and judging the prognosis of urinary, circulatory, liver, gallbladder and endocrine diseases. When a urine analyzer is used for urine analysis, the urine sample is generally dripped onto a test paper, and the test paper is sent into the machine for analysis to achieve the purpose of urine analysis. In the prior art, after sampling and dripping, the general sampling equipment needs to be cleaned, disinfected and other steps before sampling and dripping of another sample can be carried out, which affects the efficiency of urine analysis.

[0003] The Chinese patent with announcement number CN102305870B discloses a dual-channel liquid circuit system of a urine sediment analyzer, which is composed of a sampling needle, a liquid guide tube, a connecting tube, three three-way solenoid valves, channel A, channel B, three liquid pumps and a flow pool, wherein the sampling needle is connected to a three-way solenoid valve through a liquid guide tube and then separated into two sampling channels, namely channel A and channel B, channel A and channel B are merged by another three-way solenoid valve and connected to the liquid pump through the liquid guide tube, channel A is composed of a connecting tube, two three-way solenoid valves, and a liquid storage tube, wherein the two three-way solenoid valves are connected in series and the two three-way solenoid valves are connected by a liquid storage tube, channel B is composed of a connecting tube, two three-way solenoid valves, and a liquid storage tube, wherein the two three-way solenoid valves are connected in series and the two three-way solenoid valves are connected by a liquid storage tube.

[0004] In this technical solution, more liquid pumps are used to achieve sample absorption, sample addition, cleaning liquid delivery and other tasks, which will lead to more cleaning dead corners inside the system. After working for a long time, it is inevitable that cleaning is not in place, resulting in sample contamination. In addition, during the cleaning process, the dual channel only uses flushing as a cleaning method, resulting in a low cleaning effect. The dual channel is mostly for improving work efficiency. Therefore, this technical solution cannot effectively improve the efficiency of urine analysis during actual use. Summary of the invention

[0079] Partition 901, partition 901 is fixed on the inner wall of buffer tube 401, multiple connecting tubes 902 are arranged through the top of partition 901, and each connecting tube 902 is arranged obliquely, and the distance between the top end of connecting tube 902 and the inner wall of buffer tube 401 is greater than the distance between the bottom end of connecting tube 902 and the inner wall of buffer tube 401;

[0080] A cleaning component is disposed at the bottom of the connecting plate 302 and is used for cleaning the surface of the sampling needle 412 .

[0081] The tank body 402 is divided into three spaces by two pistons 409, two of which are used to store saline and alcohol, and the other space is used to transport gas, so that the following effects can be achieved:

[0082] After the first solenoid valve 404 corresponding to the first tube 405 is turned on and the switches of the other first solenoid valves 404 are turned off, as the regulating component works, the physiological saline between the two pistons 409 can enter the buffer tube 401 through the first hose 411, the first tube 405, the first solenoid valve 404 corresponding to the first tube 405 and the four-way tube 403, so as to achieve the physiological saline flushing of the buffer tube 401 and the sampling needle 412. Similarly, when the first solenoid valve 404 corresponding to the third tube 407 is turned on and the other first solenoid valves 404 are turned off, the alcohol in the space enclosed by the tank 402 and the piston 409 below enters the buffer tube 401 and the sampling needle 412 to achieve the disinfection work.

[0084] Further, the cleaning component includes:

[0085] A fixing plate 802, the fixing plate 802 is fixed to the bottom of the connecting plate 302;

[0086] Two electric push rods 803, the two electric push rods 803 are fixed on two side walls of the fixing plate 802;

[0087] Two transmission plates 804 are respectively fixed to the telescopic ends of the two electric push rods 803. Cover bodies 801 are fixed on the two transmission plates 804.

[0088] Furthermore, a waste water tank 701 is provided on the top of the base 1 , and the waste water tank 701 is connected to two third hoses 702 .

[0089] During the process of physiological saline or alcohol being discharged through the sampling needle 412, the inner wall of the sampling needle 412 is also cleaned. When the physiological saline or alcohol is discharged from the sampling needle 412 outlet, it passes through the enclosures of the two cover bodies 801, so that the physiological saline or alcohol flows along the outer surface of the sampling needle 412, and finally enters the waste water tank 701 through the third hose 702 to collect waste water. In this process, the outer surface of the sampling needle 412 is cleaned.

[0090] Further, the storage component includes:

[0092] Two one-way valves 503, which are respectively disposed through the bottom of the side walls of the first storage tank 501 and the second storage tank 502;

[0094] Under the action of the spring 410, the two pistons 409 can be reset. During the reset process of the two pistons 409, different liquids in the two first storage tanks 501 enter different spaces in the tank body 402 through the second hose 504, the one-way valve 503, and the second storage tank 502, ready for next use.

[0097] The operation of the electric heating wire increases the temperature of the gas entering the buffer tube 401 and the sampling needle 412 , thereby facilitating the drying process of the buffer tube 401 and the sampling needle 412 .

[0098] Furthermore, the supply agencies include:

[0099] Two electric slides 201, the two electric slides 201 are fixed on both sides of the top of the base 1, and cylinders 202 are fixed on the moving ends of the two electric slides 201;

[0101] The test paper 204 is fixed to the telescopic end of another cylinder 202, and the test paper 204 is used to fix the test paper.

[0102] Further, the adjustment component includes:

[0103] Two three-way pipes 602, two ports of the two three-way pipes 602 are fixed with second solenoid valves 603, the two three-way pipes 602 are symmetrically arranged, the two second solenoid valves 603 on each three-way pipe 602 are respectively connected to the two tank bodies 402, and the second solenoid valves 603 are located above the two pistons 409;

[0104] Two installation boxes 601 are respectively fixed on the two side walls of the connecting plate 302. A high-pressure air pump and a vacuum pump are respectively arranged in the two installation boxes 601. The output port of the high-pressure air pump is connected to one of the three-way pipes 602, and the input port of the vacuum pump is connected to the other three-way pipe 602.

[0105] When the high-pressure air pump is working, the two second solenoid valves 603 on the three-way pipe 602 can output gas through the corresponding three-way pipe 602. The two second solenoid valves 603 on the cover three-way pipe 602 can be controlled to increase the air pressure above the tank body 402. Similarly, the air pressure above the tank body 402 can be reduced by controlling the vacuum pump and the corresponding three-way pipe 602 and the second solenoid valve 603.

[0106] The specific working method is: when in use, first place the test tube containing the urine sample on the test tube rack 203, place the test paper for detection on the test paper board 204, then control the operation of the electric slide 201 to move the urine sample on the test tube rack 203 and the test paper on the test paper board 204 to the bottom of the two sampling needles 412 in sequence, and then the cylinder 202 is operated to make the test tube or the test paper close to the two sampling needles 412, so that the sampling or analysis preparation work can be achieved through the two sampling mechanisms;

[0107] The working principle of the sampling mechanism during the sampling process is as follows:

[0108] Under the action of the cylinder 202, the urine sample test tube rises so that the sampling needle 412 enters the test tube. Before that, it is necessary to turn on the switches of the two electric push rods 803 to separate the two cover bodies 801 so that the sampling needle 412 can smoothly enter the test tube. Then, the switch of the vacuum pump and the switch of the second solenoid valve 603 on the tank body 402 corresponding to the vacuum pump can be turned on. At this time, when the vacuum pump is working, the space above the two pistons 409 in the tank body 402 is in a negative pressure state through the corresponding three-way pipe 602 and the second solenoid valve 603. At this time, due to the action of the two springs 410, the degree of rising of the piston 409 is limited. Then the second tube body 402 is turned on. 06, and keep the other first solenoid valves 404 in a closed state, so that the gas in the buffer tube 401 can enter the tank body 402 through the four-way tube 403, the second tube body 406, and the corresponding first solenoid valve 404, that is, the air pressure in the buffer tube 401 is reduced, so that the sampling needle 412 can absorb the urine sample in the test tube, and the larger volume of the buffer tube 401 is used as a buffer to completely prevent urine from entering the tank body 402, and then the three first solenoid valves 404 are all in a closed state, and then under the action of the external air pressure, the urine sample can be temporarily stored in the sampling needle 412 and the buffer tube 401;

[0109] The motor 303 is switched on, and when the motor 303 is working, the connecting plate 302 is driven to rotate, so that the urine sample can move to the top of the test paper 204 along with the sampling needle 412, and the switch of the cylinder 202 connected to the test paper 204 is switched on, so that the test paper is close to the bottom of the sampling needle 412. At this time, the second solenoid valve 603 corresponding to the vacuum pump can be closed, that is, the corresponding three-way pipe 602 and the second solenoid valve 603 are used to disconnect the buffer tube 401 from the vacuum pump. On the contrary, the high-pressure air pump is switched on. The second solenoid valve 603 is connected, and the switch of the high-pressure air pump is turned on. When the high-pressure air pump is working, the air pressure in the upper part of the tank body 402 is increased through the corresponding three-way pipe 602 and the second solenoid valve 603, and then the gas above the tank body 402 re-enters the buffer tube 401 through the second tube body 406 and the corresponding first solenoid valve 404, so that the urine in the buffer tube 401 and the sampling needle 412 is output and dripped onto the test paper. Finally, the test paper is optically analyzed by the urine analyzer to obtain an analysis report;

[0110] When the sampling mechanism completes sampling and dripping, another sampling mechanism has moved to the top of the test tube rack 203 and completed the sampling work;

[0111] During the rotation of the gantry 301, the sampling mechanism that has just completed sampling starts to rotate in the opposite direction, that is, the sampling mechanism is reset. During the reset process, the two cover bodies 801 are firstly brought close to each other by the electric push rod 803 and the transmission plate 804, and the sealing between the two cover bodies 801 is achieved by the sealing gasket, and then the gas is continuously injected into the tank body 402. At this time, the first solenoid valve 404 corresponding to the first tube body 405 is closed, and the solenoid valve corresponding to the first tube body 405 is turned on. At this time, the piston 409 at the top moves downward under the action of the air pressure, and because the first solenoid valve 404 on the third tube body 407 is also in a closed state, and the liquid cannot be further compressed, the piston 409 at the bottom remains fixed, thereby achieving the physiological saline between the two pistons 409 entering the four-way pipe 403 through the first hose 411, the first tube body 405, and the second tube body 406 corresponding to the first tube body 405, and then entering the buffer tube 401;

[0112] When the first solenoid valve 404 corresponding to the first tube 405 is closed and the first solenoid valve 404 corresponding to the third tube 407 is switched on, the liquid between the two pistons 409 cannot be discharged, so the two pistons 409 are synchronously lowered, and the alcohol in the space below the lowest piston 409 in the tank 402 enters the buffer tube 401 through the third tube 407, the first solenoid valve 404 corresponding to the third tube 407 and the cross-tube 403;

[0113] When the physiological saline or alcohol enters the buffer tube 401, it will be blocked by the partition 901 and then discharged through the inclined connecting tube 902. Due to the setting of the connecting tube 902, the physiological saline or alcohol can flow along the inner wall of the buffer tube 401, ensuring the cleaning effect of the inner wall of the buffer tube 401;

[0114] During the process of the physiological saline or alcohol being discharged through the sampling needle 412, the inner wall of the sampling needle 412 is also cleaned. When the physiological saline or alcohol is discharged from the sampling needle 412 outlet, it passes through the enclosures of the two cover bodies 801, so that the physiological saline or alcohol flows along the outer surface of the sampling needle 412, and finally enters the waste water tank 701 through the third hose 702, so that the waste water is collected. In this process, the outer surface of the sampling needle 412 is cleaned;

[0115] Subsequently, the switch of the first solenoid valve 404 corresponding to the second tube body 406 is directly turned on, and the switch of the heating wire is turned on, and the gas is heated by the heating wire, so that the high-temperature gas passes through the second tube body 406, the first solenoid valve 404 corresponding to the second tube body 406, and the four-way pipe 403 and enters the buffer tube 401. During the high-temperature gas flowing into the buffer tube 401, the sampling needle 412, and the gap between the sampling needle 412 and the cover body 801, the excess moisture is blown away, and at the same time, the volatilization of alcohol and the evaporation of moisture are accelerated by the high-temperature gas, thereby achieving the cleaning of the inside and outside of the sampling needle 412 and the cleaning of the inside of the buffer tube 401, ensuring the efficient and rapid sampling work;

[0116] After cleaning, the sampling mechanism is reset to perform the next sampling operation, and the two pistons 409 are reset under the action of the spring 410. During the reset of the two pistons 409, different liquids in the two first storage tanks 501 enter different spaces in the tank body 402 through the second hose 504, the one-way valve 503, and the second storage tank 502, and are ready for the next use.

[0117] During the process of cleaning the buffer tube 401 and the sampling needle 412, the connecting plate 302 is in a rotating state, so that the other sampling mechanism completes sampling and moves toward the test paper, so as to realize alternating sampling and cleaning of the dual liquid paths, thereby achieving efficient analysis of urine.

[0118] It is worth noting that the motor 303 in the present invention is a forward and reverse motor, and the motor 303 rotates one hundred and eighty degrees each time. In addition, each electrical component in the present invention can be controlled by an automated circuit to ensure the accuracy of the control of the electrical components. The automation involved in the present invention is relatively simple, and the automated circuit is relatively mature, and it is not the main innovation of the present invention, so it will not be repeated.
