Detailed Description
The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
A first embodiment of the reagent evaporation preventing apparatus of the present invention is shown in fig. 1 to 3, and the reagent evaporation preventing apparatus includes a support 10, a guide rail 20, a sealing cover 30, and a reagent table 40; the bracket 10 is arranged along the orientation extension of the top surface of the guide rail 20; the sealing cover 30 is movably installed on the bracket 10, the sealing cover 30 is opposite to and separated from the top surface of the guide rail 20, and the sealing cover 30 is used for moving toward and away from the top surface of the guide rail 20; the reagent table 40 is mounted on the top surface of the guide rail 20, and the movement path of the reagent table 40 passes through the sealing cover 30 opposite to the guide rail 20.
When the reagent is used, the reagent is placed in the test tube 50 for use, so that after the reagent is used, the test tube 50 with the reagent can be placed on the reagent table 40 for installation and fixation, for example, a circular jack can be arranged on the reagent table 40, and the test tube 50 can be directly inserted into the circular jack for fixation; then, the reagent table 40 is controlled to move on the guide rail 20 until the reagent table 40 moves to the lower part of the sealing cover 30, and at this time, the sealing cover 30 can be controlled to move downwards until the sealing cover 30 stably presses the opening of the test tube 50, thereby reliably preventing the reagent from evaporating.
Regarding the guide rail 20, it is intended to define the moving path of the reagent table 40 to ensure that the reagent table 40 can move to be opposite to the sealing cover 30, so the guide rail 20 does not define the moving path of the reagent table 40 only, and may be a meandering path, a linear path, or a combination thereof; however, in order to reduce the complexity of the movement control of the reagent table 40, the structure shown in fig. 1 and 2 may be adopted, in which the guide rail 20 is provided as a straight rail, the movement path of the reagent table 40 is a straight line, and the sealing cover 30 is provided at the position corresponding to the end point of the movement path of the reagent table 40.
With reference to the directions shown in fig. 1 and 2, in this case, the guide structure of the guide rail 20 is disposed on the top surface of the guide rail 20, the reagent table 40 is mounted on the top surface of the guide rail 20 and is installed in cooperation with the guide structure of the guide rail 20, so that the reagent table 40 moves left and right on the guide rail 20, the leftmost side of the movement path of the reagent table 40 is the starting point of the movement path of the reagent table 40, and the rightmost side of the movement path of the reagent table 40 is the end point of the movement path of the reagent table 40, so that when the reagent table 40 reaches the end point of the movement path, the sealing cover 30 can be disposed opposite to the reagent table 40, thereby sealing and covering the reagent.
It should be noted that the reagent table 40 may be moved by manual driving or by motor driving, and particularly in the case of the electric control method, if the moving path of the reagent table 40 is too complicated, the structural complexity of the reagent evaporation preventing device is greatly increased, and the reagent evaporation preventing device is likely to malfunction, so that the moving path of the reagent table 40 is limited to a straight line, and thus the occurrence of this phenomenon can be reliably avoided.
Regarding the bracket 10, the function is to realize the installation and fixation of the sealing cover 30, and on the basis of ensuring the mutual separation of the sealing cover 30 and the guide rail 20, the up-and-down movement of the sealing cover 30 is also required to be realized; there are various ways to move the sealing cover 30 up and down, and a preferred embodiment is as shown in fig. 1 and fig. 2, one end of the bracket 10 away from the top surface of the guide rail 20 is provided with a supporting plate 11, the supporting plate 11 is arranged opposite to the top surface of the guide rail 20, the supporting plate 11 is provided with a through hole (not shown), a guide shaft 60 is installed in the through hole, and the guide shaft 60 is used for moving towards and away from the top surface of the guide rail 20; the sealing cover 30 is disposed between the supporting plate 11 and the top surface of the guide rail 20, and the sealing cover 30 is connected to the guide shaft 60.
Referring to the directions shown in fig. 1 and 2, one end of the bracket 10 may be fixedly connected to the guide rail 20, the other end of the bracket 10 may be provided with a supporting plate 11, and the supporting plate 11 is disposed above the top surface of the guide rail 20, so that the sealing cover 30 moves downward due to gravity when the sealing cover 30 is not subjected to an external force; when the reagent table 40 transports the test tube 50 to the lower part of the sealing cover 30, the sealing cover 30 can be controlled to move upwards, and then the sealing cover 30 can naturally stabilize the opening of the test tube 50 due to gravity, so that the purpose of preventing the reagent from evaporating is achieved.
In order to further optimize the automation of the reagent evaporation preventing apparatus, the sealing cover 30 may be provided with a transition surface 31 as shown in fig. 1 and 2, one side of the transition surface 31 is connected to a surface of the sealing cover 30 facing the starting point of the reagent table 40 moving path, the other side of the transition surface 31 is connected to a surface of the sealing cover 30 facing the top surface of the guide rail 20, and the distance between the transition surface 31 and the top surface of the guide rail 20 is gradually reduced in the direction from the starting point of the reagent table 40 moving path to the ending point of the reagent table 40 moving path.
Therefore, in the process that the reagent table 40 drives the test tube 50 to move towards the sealing cover 30, the opening of the test tube 50 can abut against the transition surface 31, along with the continuous movement of the reagent table 40, the test tube 50 can push the sealing cover 30 to move upwards, and after the reagent table 40 stops moving, the sealing cover 30 can automatically stabilize the opening of the test tube 50 due to gravity.
The transition surface 31 may be a flat inclined surface or an arc transition surface, and both can realize the linkage between the test tube 50 and the sealing cover 30.
Regarding the guide shaft 60, the function of the guide shaft 60 is to move the sealing cover 30 up and down, and a preferred structure of the guide shaft 60 can be as shown in fig. 1 to 3, that is, the guide shaft 60 includes a head portion 61 and a shaft body 62, the diameter of the head portion 61 is larger than that of the through hole, one end of the shaft body 62 is connected to the head portion 61, and the other end of the shaft body 62 passes through the through hole to be connected to the sealing cover 30.
Therefore, when the sealing cover 30 moves down naturally due to gravity, the head 61 will abut against the upper surface of the supporting plate 11 to prevent the sealing cover 30 from falling completely; in order to enhance the sealing performance of the sealing cover 30, a spring or a tension spring may be sleeved on the shaft body 62.
For example, when the shaft 62 is sleeved with a spring, the spring is arranged between the lower surface of the supporting plate 11 and the upper surface of the sealing cover 30, so that when the sealing cover 30 is pressed towards the opening of the test tube 50, the spring can also push the sealing cover 30 towards the opening of the test tube 50 to enhance the pressure of the sealing cover 30 on the opening of the test tube 50.
Similarly, when the shaft 62 is sleeved with a tension spring, the tension spring will be disposed between the lower surface of the head 61 and the upper surface of the supporting plate 11, so when the sealing cover 30 presses against the opening of the test tube 50, the tension spring will pull the sealing cover 30 to move downward, i.e. the pressure of the sealing cover 30 against the opening of the test tube 50 is enhanced.
In addition, the sealing cover 30 can be a silica gel cover, and after the sealing cover 30 is made of elastic materials such as silica gel, the sealing performance between the sealing cover 30 and the opening of the test tube 50 can be further enhanced.
Further, in order to define the moving path of the reagent table 40, the structure shown in fig. 1 and 2 may be adopted, that is, the rack 10 is further provided with a blocking plate 12, the blocking plate 12 is provided on the side of the sealing cover 30 away from the starting point of the moving path of the reagent table 40, and the blocking plate 12 is used for blocking the movement of the reagent table 40 loaded with the reagent.
With reference to the directions shown in fig. 1 and 2, the upper side of the baffle 12 can be fixedly connected to the right side of the supporting plate 11, so that the baffle 12 is connected to the supporting plate 11 in an L-shaped configuration, and therefore, when the manual control reagent table 40 continues to drive the test tube 50 to move right, the test tube 50 abuts against the left side surface of the baffle 12, thereby limiting the excessive movement of the reagent table 40.
If the reagent table 40 is controlled to move electrically, a corresponding pressure sensor may be disposed on the reagent table 40, and when the test tube 50 abuts against the baffle 12, the pressure sensor may be triggered by the blocking of the reagent table 40, and then the reagent table 40 may be stopped from moving continuously by a corresponding control circuit.
Of course, the baffle 12 does not have to be connected and fixed with the supporting plate 11, and the baffle 12 can be separated from the supporting plate 11, so that it is only necessary to ensure that the baffle 12 extends and is arranged below the supporting plate 11, and the test tube 50 can be blocked.
The second embodiment of the reagent evaporation preventing apparatus of the present invention is shown in fig. 4, which is substantially the same as the first embodiment except that a lifting mechanism 70 is provided on the support 10, the sealing cover 30 is connected to the lifting mechanism 70, and the lifting mechanism 70 is used to control the sealing cover 30 to move toward and away from the guide rail 20.
That is, the up-and-down movement of the sealing cap 30 is achieved not by gravity but by the direct driving of the elevating mechanism 70, which is advantageous in that the moving distance of the sealing cap 30 can be directly controlled to ensure that the sealing cap 30 can apply sufficient pressure to the opening of the test tube 50, thereby resulting in better sealing performance.
In order to optimize the automatic control of the lifting mechanism 70, as shown in fig. 4, the reagent evaporation preventing apparatus may further include an infrared sensor 80, the infrared sensor 80 is disposed on a surface of the support 10 facing the guide rail 20, the infrared sensor 80 is disposed between the sealing cover 30 and a top surface of the guide rail 20, the infrared sensor 80 is configured to detect whether the reagent table 40 filled with the reagent reaches an end of a movement path, and when the reagent table 40 reaches the end of the movement path, the lifting mechanism 70 is configured to control the sealing cover 30 to move toward the reagent table 40.
With reference to the direction shown in fig. 4, the sensing area of the infrared sensor 80 can be set to face the direction perpendicular to the moving path of the reagent table 40, so when the reagent table 40 drives the test tube 50 to move below the sealing cover 30, the test tube 50 will block the infrared sensor 80, thereby indicating that the reagent table 40 has reached the end point of the moving path, and the lifting mechanism 70 can control the sealing cover 30 to move downwards, so as to stabilize the opening of the test tube 50.
The utility model also discloses a detection device, which comprises a detection mechanism and the reagent evaporation-proof device, wherein the moving path of the reagent table 40 passes through the detection mechanism; therefore, after the reagent is applied to the testing device, the reagent table 40 can directly transport the test tube 50 to the sealing cover 30 for sealing, thereby providing great convenience for the preservation of the reagent.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
