[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0027] The present embodiment discloses an automatic revolving door for medical sample detection equipment and the medical sample detection equipment including the automatic revolving door, wherein the medical sample detection equipment may be, but is not limited to, a fluorescent immunoassay analyzer, an enzyme-labeled analyzer, a biochemical analyzer, a chemiluminescence analyzer or a PCR instrument.
[0028] like Figures 1 to 4 As shown, the automatic rotating door of the medical sample detection device includes a door assembly, a driving device 1, a first sensor 21, a second sensor 22, a third sensor 23 and a controller. The medical sample detection device includes a box body, and a detection cavity 3 is formed inside the box body.
[0029] The driving device 1 is used to drive the door assembly to rotate to realize the opening and closing of the door assembly, so that the door assembly can open or cover the opening end 31 of the detection chamber 3, creating a good detection environment for the medical sample detection equipment. When there is no detection task or the detection task is being performed, the door assembly covers the opening end 31 of the detection chamber 3 to prevent foreign matter from entering the detection chamber 3 and ensure the cleanliness of the detection chamber 3; when the reagent card 4 to be detected needs to be inserted into the specified position in the detection chamber 3, the door assembly opens the opening end 31 of the detection chamber 3 to ensure the smooth execution of the card insertion action.
[0030] The first sensor 21 is used to confirm whether there is an object approaching the door assembly. The first sensor 21 is set on the outside of the door assembly. In this embodiment, the "object" mainly refers to "the user holding the test reagent card 4"; and the judgment standard of "approaching" is not limited, depending on the specific setting position of the first sensor 21. If the first sensor 21 can sense it, it is determined that a user is holding a card approaching the door assembly. If there is no detection task being performed in the detection chamber 3 at this time, the door assembly opens for the user to insert the test reagent card 4 into the detection chamber 3. After the first sensor 21 confirms that there is an object approaching the door assembly, if no object is sensed, it is determined that the user has completed the card insertion and the user's hand has left the inside of the detection chamber 3 and the surrounding area.
[0031] In order to prevent the door assembly from being opened by mistake due to the user approaching by mistake or other foreign objects approaching by mistake, a second sensor 22 is provided to confirm whether an object has entered the detection cavity 3. The second sensor 22 is provided on the inner side of the door assembly, and only when the second sensor 22 senses that the user has inserted the reagent card 4 to be detected into the detection cavity 3 can it be confirmed that the user is really going to use the medical sample detection device to perform the detection task.
[0032] A third sensor 23 is provided in the detection chamber 3 to sense whether the reagent card 4 to be detected is inserted into place. The specific location of the third sensor 23 is not limited. Preferably, the third sensor 23 is provided at the bottom end of the card slot. When the reagent card 4 to be detected is completely inserted into the card slot, the bottom edge of the reagent card 4 to be detected abuts against the bottom end of the card slot, and the third sensor 23 can confirm that the card has been inserted into place.
[0033] The controller (not shown) is respectively connected to the driving device 1, the first sensor 21, the second sensor 22 and the third sensor 23. The controller controls the driving device 1 to open or close the door assembly according to the signal of the first sensor 21, thereby achieving smooth opening and closing of the door assembly.
[0034] The automatic revolving door of the medical sample testing equipment uses a sensor to determine whether the door assembly needs to be opened or closed. The driving device 1 is used to drive the door assembly to rotate to achieve the opening and closing of the door assembly. The overall structure is simple and reasonable, the space occupancy is small, the failure rate is low, the manufacturing cost and the use cost are very low, and it is suitable for various medical sample testing equipment.
[0035] The specific structure of the door assembly is not limited, as long as it can open or cover the open end 31 of the detection cavity 3. Preferably, the door assembly includes a door body 51 and a rotating connection block 52 that form an integral structure, the rotating connection block 52 is fixedly connected to the driving device 1 and can rotate under the drive of the driving device 1, and the rotating connection block 52 is configured to drive the door body 51 to open or close when rotating.
[0036] Of course, it is also feasible to directly fix the sheet-like door body 51 to the driving device 1, but in this case, the output shaft of the driving device 1 is required to extend a long distance, and the stability of the door body 51 is poor when rotating. The use of the rotating connection block 52 can solve this problem well. The rotating connection block 52 can be inserted into a device such as a bearing, and can support the rotating connection block 52 without affecting the rotation of the rotating connection block 52 around the axis, thereby preventing the rotating connection block 52 from moving in the radial direction.
[0037] The specific shape of the door body 51 is not limited, as long as it can completely cover the open end 31 of the detection cavity 3. Preferably, the door body 51 is rectangular, and the rotating connection block 52 is connected to a corner of the door body 51. When the rotating connection block 52 drives the door body 51 to rotate under the drive of the driving device 1, the door body 51 can open the open end 31 of the detection cavity 3 to the greatest extent at the smallest possible rotation angle, avoiding the edge of the door body 51 from hindering the user from inserting the card, and the energy consumption of the driving device 1 is lower.
[0038] On the basis of the above structure, the automatic revolving door of the medical sample testing equipment further includes a bracket 6. The bracket 6 is fixed to the inner side of the box of the medical sample testing equipment, and the driving device 1 is arranged on the bracket 6, so as to ensure that the driving device 1 is always in a stable state, thereby ensuring that the door body 51 can maintain a stable spatial posture whether it is rotating or stationary, and avoiding the obstruction of card insertion due to the shaking of the door body 51.
[0039] On the basis of the above structure, the automatic rotating door of the medical sample detection equipment further includes a rotation zero position optical coupler 71 and a rotation zero position optical coupler baffle 72. The rotation zero position optical coupler baffle 72 is in a sheet shape, and the rotation zero position optical coupler 71 is in a U shape. When the sheet-shaped rotation zero position optical coupler baffle 72 is inserted into the opening of the U-shaped rotation zero position optical coupler 71, the signal of the rotation zero position optical coupler 71 will change, thereby judging that the door body 51 is in the maximum opening position.
[0040] The rotational zero position optical coupling baffle 72 is preferably installed on the rotating connection block 52. When the rotating connection block 52 rotates under the drive of the driving device 1, the rotational zero position optical coupling baffle 72 can rotate synchronously with the rotating connection block 52. The rotational zero position optical coupling 71 is set on the bracket 6 and is always in a stationary state. The specific setting position of the rotational zero position optical coupling baffle 72 on the rotating connection block 52 is determined by calculation to ensure that the rotational zero position optical coupling baffle 72 is inserted into the rotational zero position optical coupling 71 when the door body 51 is at the maximum open position. The controller is connected to the rotational zero position optical coupling 71. When the signal of the rotational zero position optical coupling 71 changes, the controller turns off the driving device 1, and the door body 51 stops rotating, so as to avoid excessive rotation of the door body 51 causing interference between the door body 51 and other structures, and can reduce the energy consumption of the driving device 1.
[0041] The specific structure of the driving device 1 is not limited, as long as it can drive the door body 51 to rotate. Preferably, the driving device 1 is a motor, and the rotating connection block 52 of the door assembly is fixedly connected to the output shaft of the motor. When the output shaft rotates around its own axis, it can drive the rotating connection block 52 to rotate synchronously. When the rotating connection block 52 rotates, it can drive the door body 51 to swing around the connection part, so as to realize the opening and closing of the door body 51.
[0042] The specific structures of the three groups of sensors are not limited, as long as they can realize their respective functions. Preferably, the first sensor 21 and / or the second sensor 22 are opposing optical couplers, and each group of opposing optical couplers includes a signal transmitting end and a signal receiving end. When an object is blocked between the signal transmitting end and the signal receiving end, the signal cannot be received normally, thereby determining that an object is close to the door assembly and an object has entered the detection cavity 3. Opposing optical couplers have rich product types, mature production processes, and low product costs, thereby ensuring that the automatic revolving door of the medical sample detection equipment is low in cost and easy to design and process.
[0043] The third sensor 23 is preferably a reflective optical coupler. The signal transmitting end of the reflective optical coupler is the signal receiving end. When the reagent card 4 to be detected is not completely inserted into the card slot, the signal emitted by the signal transmitting end travels until it hits the top surface of the detection cavity 3 and returns to the signal receiving end. The travel is long, and the time interval between the signal emission and reception is long; when the reagent card 4 to be detected is completely inserted into the card slot, the signal emitted by the signal transmitting end hits the reagent card 4 to be detected and then returns to the signal receiving end. The travel is short, and the time interval between the signal emission and reception is short. The third sensor 23 can confirm whether the reagent card 4 to be detected is in place based on the time difference.
[0044] When using, Figure 3 As shown, when the user holds the reagent card 4 to be detected and is close enough to the door body 51, the first sensor 21 is blocked, the door body 51 and the rotating connecting block 52 rotate under the drive of the driving device 1, and the open end 31 of the detection chamber 3 is opened; the user sends the reagent card 4 to be detected into the card slot of the detection chamber 3, the second sensor 22 is blocked, and the controller determines that the reagent card 4 to be detected is inserted; the user continues to push the reagent card 4 to be detected inward along the card slot until the bottom edge of the reagent card 4 to be detected abuts against the bottom end of the card slot, the third sensor 23 is blocked, and the controller determines that the reagent card 4 to be detected is in place; the user releases the reagent card 4 to be detected and exits the detection chamber 3, as shown in FIG. Figure 4 As shown, the second sensor 22 and the first sensor 21 successively resume the unblocked state, the controller determines that the card insertion is completed, the driving device 1 drives the door body 51 and the rotating connecting block 52 to rotate, the door body 51 blocks the opening end 31 of the detection cavity 3, and enters the test process.
