Description

Sample analysis and detection unit

Technical Field

The invention relates to the technical field of in-vitro diagnosis, in particular to a sample analysis and detection unit.

Background

Blood count is one of the most common blood test items in the medical field, and since cells (e.g., white blood cells, red blood cells, platelets, etc.) circulating in the blood stream of a human body can provide an overview of the overall health of a patient, a medical professional can determine certain disease states based on the increase or decrease of certain types of cells in the blood stream. Initially, the number of blood cells used by the medical professional was manual: blood smears (also known as blood films or peripheral blood smears) made from patient blood samples are observed under a microscope, and as technology advances, this is now commonly done by means of a hemocytometer (also known as a blood cell analyzer).

Inside the hemocytometer, the test tube is driven by the test tube seat to reciprocate between the sample placing position and the sample absorbing position, the test tube seat loads the test tube at the sample placing position, after loading is completed, the test tube seat can move to the sample absorbing position with the test tube, and the follow-up operations of puncturing, sample absorbing, analyzing, cleaning and the like are performed in a preset process until a final test result is output.

The existing hemocytometer generally has a conventional tube sample injection mode and a preferential tube sample placement mode.

Under conventional test tube sampling mode, test tube holder can be in inhale a kind position, put the sample position and reciprocate, after sampling device moves the test tube to put the sample position, grabbing device descends and snatchs the test tube, then grabbing device carries the test tube upwards to the position of test tube holder top, and the test tube holder outwards moves to put the sample position again, and grabbing device descends in order to place the test tube in the test tube holder, finally, is transported the test tube to inhaling a kind position by test tube holder displacement, carries out the operation of inhaling a kind. In this mode of the priority tube placement mode, the tube holder, starting from the sample suction position, no longer remains in the sample placement position, but moves to the priority tube placement position, where the operator manually loads the tube.

The structure has two functions of conventional test tube sample injection and preferential treatment test tube sample injection, however, because the sample injection and detection processes of the conventional test tube and the preferential treatment test tube all need to occupy the test tube seat, in the sample injection or detection process of the conventional test tube, if the preferential treatment test tube needs to be loaded, the test tube seat cannot be popped up before the detection is completed because the test tube seat is loaded with the conventional test tube, the test tube seat cannot be moved in the sampling process, and the like, an operator can only hold the preferential treatment test tube beside the instrument to wait for the detection process of the previous test tube to finish, and can place the preferential treatment test tube in the test tube seat, so that a large amount of waiting time of the operator is consumed, and the preferential treatment test tube is placed in a short time, so that the risk of contact infection is increased.

Compared with the mode that the test tube seat 7 actively moves between the sample placing position and the sample sucking position 101 in the prior art, in the scheme, the grabbing component 601 actively moves, the test tube seat 7 is kept motionless, the problem that the test tube seat 7 is easy to interfere with other components or pipelines in the moving process in the prior art is solved, and the fault rate is reduced. In addition, the test tube grabbing device 6 is further provided with a swing mixing assembly, the test tube grabbing device 6 shakes after taking out the conventional test tube 201 from the first test tube grabbing position 102, samples in the conventional test tube 201 are mixed evenly, and then the conventional test tube 201 is placed in the test tube seat 7 of the sample sucking position 101.

It will be appreciated that the conventional test tube 201 or the priority test tube 202 may be placed at the first test tube gripping position 102 or the second test tube gripping position 103 by manual operation, for example, for the occasional priority test tube 202, only one second test tube gripping position 103 may be reserved in the sample analyzer, and meanwhile, a moving mechanism is not required to be separately provided, so that an operator may also directly and manually place the priority test tube 202 at the second test tube gripping position 103, and further perform subsequent operations by the test tube gripping device 6.

In this embodiment, the conventional test tube 201 or the preferential treatment test tube 202 is moved by the first test tube moving device 4 and the second test tube moving device 5, respectively, and the first test tube moving device 4 and the second test tube moving device 5 mainly function to transfer the test tube to the gripping position, and then the test tube gripping device 6 places the test tube to the sample sucking position 101 for sample sucking operation. Specifically, the first tube moving device 4 is capable of transporting the normal tube 201 to the first tube gripping position 102, and the second tube moving device 5 is capable of transporting the priority tube 202 to the second tube gripping position 103, and then, the subsequent operation is performed by the tube gripping device 6.

The conventional test tube 201 in this embodiment is moved by the sample introduction device 9, specifically, the sample introduction device 9 includes a first storage portion 901 and a second storage portion 902, the first storage portion 901 is used for storing the conventional test tube 201 loaded with a sample to be tested, the second storage portion 902 is used for storing the conventional test tube 201 after the test is completed, the sample introduction device 9 generally includes a conveying device for conveying the conventional test tube 201 from the first storage portion 901 to the second storage portion 902, in this embodiment, the conveying device includes a conveyor belt, the conventional test tube 201 is firstly loaded on a test tube rack, and then is conveyed by the conveyor belt from the first storage portion 901 to the second storage portion 902 together with the test tube rack, in this embodiment, the first test tube moving device 4 for conveying the conventional test tube 201 to the first test tube grabbing position 102 is disposed on the sample introduction device 9, specifically, the first test tube moving device 4 conveys the conventional test tube 201 between the first storage portion 901 and the second storage portion 902, namely: the conveyor belt that carries the conventional test tube 201 between the first storage portion 901 and the second storage portion 902 serves as the first test tube moving device 4 that conveys the conventional test tube 201 to the first test tube gripping position 102, and the first test tube gripping position 102 is provided on the conveying path of the first test tube moving device 4, so that the beneficial effect of the structure is that: firstly, the conventional test tube 201 is placed through the sample injection device 9 with a lower height position, and then the test tube grabbing device 6 is lifted to the test tube seat 7 positioned on the upper layer, so that the device has the advantages of low height of placing the conventional test tube 201 on a sample loading machine, easiness in placing the conventional test tube 201 by an operator, convenience in operation, small occupied table-board space of a two-layer structure of the whole analyzer and the like.

During actual use, operators find that, in addition to the conventional test tubes 201 which are automatically queued for testing in sequence, in operation, priority test tubes 202 which require priority handling are often encountered. The conventional test tube 201 and the priority test tube 202 are generally not significantly different from each other in terms of structure, namely: both the conventional tube 201 and the priority tube 202 may be referred to as tubes, the main differences being that: the priority handling tube 202 needs to be subjected to priority handling by the queue, so that the detection waiting time of the priority handling tube 202 is relatively short, while the detection waiting time of the conventional tube 201 is relatively long because the conventional tube 201 is sequentially checked in line, and it is difficult to process the priority handling tube 202 in time if the conventional structure is adopted.

To this end, in order to meet the priority handling requirement, the sample analysis and detection unit of the present embodiment is provided with a second test tube moving device 5, the second test tube moving device 5 is mainly used for transferring the priority handling test tube 202, which includes a priority test tube accommodating unit for accommodating the priority handling test tube 202, and an actuating mechanism is also provided in the second test tube moving device 5, by which the priority test tube accommodating unit is reciprocated between a second test tube gripping position 103 and a sample sucking position 101, in the present embodiment, the second test tube moving device 5 is provided on the sample feeding device 9, and the track of the linear motion of the gripping member 601 is driven by the lateral displacement mechanism of the test tube gripping device 6 to be respectively stereo-intersected with the first test tube gripping position 102 and the second test tube gripping position 103, that is: from the top view, the gripping part 601 is linearly reciprocated in the front and back directions, the first test tube gripping position 102 and the second test tube gripping position 103 are both located on the moving track of the gripping part 601 in the front and back directions, so that the gripping part 601 only needs to move along the same linear direction to cover the first test tube gripping position 102, the second test tube gripping position 103 and the sample suction position 101, the structure and the control of the gripping device are facilitated to be simplified, and compared with the structure and the control of arranging the second test tube moving device 5 in the inner space of an instrument above the sample injection device 9, the upper machine position of the test tube 202 is lower, the test tube is easier to place by operators, and the effects of convenience in operation, small occupied space and the like are achieved. In addition, the front side of the sample analysis and detection unit of this embodiment is further provided with a front cover, and the first test tube grabbing position 102 and/or the second test tube grabbing position 103 are/is located on the inner side of the front cover.

By adopting such a mode, because the test tube grabbing device 6 capable of translating is adopted in the scheme, compared with the mode that the conventional test tube 201, the priority treatment test tube 202 and the test tube seat 7 in the prior art are respectively provided with a single translation mechanism, the scheme realizes the motion through the test tube grabbing device 6, has a more simplified structure, is beneficial to structural layout in such a mode, and particularly, the moving mechanism of the test tube grabbing device 6 can be arranged at the top of the analyzer to avoid occupying valuable space in the analyzer.

Compared with the structure that the conventional test tube 201 and the priority test tube 202 share the same test tube moving device in the traditional scheme, the sample analysis and detection unit provided by the invention has the advantages that by adding the second test tube moving device 5 which can work independently, when the priority test tube 202 needs to be placed, the second test tube moving device 5 can move out and receive the test tube at any time, and the conventional test tube 201 does not need to wait for detection to finish until the accommodating unit of the first test tube moving device 4 is free, so that the waiting time of operators is greatly shortened, the time of exposing the priority test tube 202 to the air is shortened, the risk of contacting with external infection is reduced, and in addition, the insertion of the priority test tube 202 is not influenced by detection in operation, thereby being beneficial to adding the priority test tube 202 at any time.

The suction component 3 in this embodiment can be moved to the sample sucking position 101 as required, and at the same time, this suction component 3 can be moved to the side of the sample sucking position 101 as required to wait so as to avoid interference, so that it is beneficial to avoiding other components, and avoiding interference and other situations in the process of placing the test tube into the test tube seat 7.

When the rotating device 1001 can drive the conventional test tube 201 or the preferential treatment test tube 202 to rotate at the side of the conventional test tube 201 or the preferential treatment test tube 202 at the sample sucking position 101, the rotating device 1001 is movably arranged, when the conventional test tube 201 or the preferential treatment test tube 202 needs to be rotated, the rotating device 1001 is moved to the sample sucking position 101, so that the rotating device 1001 is connected with the conventional test tube 201 or the preferential treatment test tube 202 at the sample sucking position 101, and the rotating device 1001 is started to rotate the conventional test tube 201 or the preferential treatment test tube 202; after the rotation is completed, the rotation device 1001 is reset.

In order to reduce the height, it is preferable that the above-mentioned rotating means 1001 is capable of driving the conventional cuvette 201 or the priority cuvette 202 to rotate at the side of the conventional cuvette 201 or the priority cuvette 202 of the sample-sucking position 101. In this case, the rotating device 1001 includes: a driving part 1002 for contacting the conventional test tube 201 or the priority test tube 202, and a rotation driving part 1003 for driving the driving part 1002 to rotate the conventional test tube 201 or the priority test tube 202. It will be appreciated that the rotation driving part 1003 drives the rotation driving part 1002 to rotate.

The rotating device 1001 uses the friction force between the driving component 1002 and the conventional test tube 201 or the priority test tube 202 to drive the conventional test tube 201 or the priority test tube 202 to rotate, so that fewer components are required and the structure is simpler.

When the conventional test tube 201 or the priority test tube 202 rotates under the action of the friction force, the conventional test tube 201 or the priority test tube 202 is relatively easy to shift, and in order to avoid shifting the conventional test tube 201 or the priority test tube 202, the rotating device 1001 further includes: an auxiliary member 1004, disposed opposite the driving member 1002, for limiting the conventional test tube 201 or preferentially treating the test tube 202.

The driving part 1002 and the auxiliary part 1004 are disposed opposite to each other, that is, the driving part 1002 and the auxiliary part 1004 are respectively disposed at two sides of the axis of the conventional test tube 201 or the priority test tube 202, so that the stress balance of the conventional test tube 201 or the priority test tube 202 is ensured, and the stability of the conventional test tube 201 or the priority test tube 202 during rotation is improved.

Since the auxiliary member 1004 serves to limit the conventional test tube 201 or the priority test tube 202, the above-mentioned auxiliary member 1004 also serves to contact the conventional test tube 201 or the priority test tube 202. When the driving part 1002 rotates, the auxiliary part 1004 may or may not rotate.

For the height relative position relationship between the driving component 1002 and the auxiliary component 1004, the design may be performed according to practical needs, for example, the bottom end of the driving component 1002 is flush with the bottom end of the auxiliary component 1004, or the top end of the driving component 1002 is flush with the top end of the auxiliary component 10047, or the bottom end of the auxiliary component 1004 is higher than the bottom end of the driving component 1002, the top end of the auxiliary component 1004 is lower than the top end of the driving component 1002, or the bottom end of the driving component 1002 is higher than the bottom end of the auxiliary component 1004, and the top end of the driving component 1002 is lower than the top end of the auxiliary component 1004.

The driving member 1002 and the auxiliary member 1004 may be plate-shaped, wheel-shaped or block-shaped. Preferably, the driving part 1002 is a driving wheel, and the auxiliary part 1004 is an auxiliary wheel. In this way, the conventional test tube 201 or the priority test tube 202 is driven to rotate in a rolling manner, so that the rotation resistance is reduced, and the energy loss is reduced; by means of rolling, the influence on the firmness of information code adhesion is reduced, and particularly, the situation that the information code on a conventional test tube 201 or a priority processing test tube 202 is not firm in adhesion or is provided with a flanging is effectively improved, so that the rotating effect is effectively improved, and the reliability is improved.

In order to improve the rotation effect, the diameter of the driving wheel is larger than that of the auxiliary wheel, and the number of the driving wheels is smaller than that of the auxiliary wheels. Specifically, the number of driving wheels is one, and the number of auxiliary wheels is two; or the number of driving wheels is two, and the number of auxiliary wheels is more than three, which is not limited in this embodiment.

When the number of the driving wheels is one and the number of the auxiliary wheels is two, the two auxiliary wheels are symmetrically arranged about the axis of the driving wheels, so that the stress balance of the conventional test tube 201 or the priority treatment test tube 202 is effectively improved.

The driving part 1002 is used for contacting with the conventional test tube 201 or the priority test tube 202, and the friction force between the driving part 1002 and the conventional test tube 201 or the priority test tube 202 drives the conventional test tube 201 or the priority test tube 202 to rotate. In order to increase the friction force between the driving part 1002 and the conventional test tube 201 or the priority test tube 202, a rubber ring is arranged outside the driving part 1002, and the driving part 10029 is used for contacting with the conventional test tube 201 or the priority test tube 202 through the rubber ring.

In addition, when the rubber ring is damaged, only the rubber ring is replaced, the driving component 1002 does not need to be replaced, and the maintenance cost is reduced.

When the tube gripping device 1101 grips the conventional tube 201 and the priority handling tube 202, the conventional tube 201 and the priority handling tube 202 can be rotated about their axes, and when the gripping structure grips the conventional tube 201 and the priority handling tube 202, the rotation of the conventional tube 201 and the priority handling tube 202 can be achieved by the driving of the rotation driving part 1003.

The limiting plate 1201 is used to release the restriction of the conventional test tube 201 and the priority test tube 202 when the limiting plate 1201 moves to the preset position, which indicates that the conventional test tube 201 and the priority test tube 202 can be separated from the test tube holder 7 at this time, and the conventional test tube 201 and the priority test tube 202 on the test tube holder 7 can be grasped by the grasping module and released to the test tube holder 7 when the limiting plate 1201 moves to the preset position.

When the test tube gripping device 6 is required to grip the conventional test tube 201 and the priority test tube 202 on the test tube holder 7 or release the conventional test tube 201 and the priority test tube 202 from the test tube holder 7, the limiting plate 1201 is moved to the preset position so that the limiting plate 1201 releases the limitation on the conventional test tube 201 and the priority test tube 202, thereby avoiding the limiting plate 1201 interfering with the gripping and release of the conventional test tube 201 and the priority test tube 202 by the gripping module, and ensuring that the gripping module can grip and release the conventional test tube 201 and the priority test tube 202.
