Description

Test tube classification method

Technical Field

The invention relates to a test tube classification method, in particular to a test tube classification method for inspection.

Background

Test tubes are used as vessels for testing and are used in hospital laboratories. At present, the general procedure for blood sample detection is: (1) medical staff collects blood samples by using different test tubes according to different test items; (2) sticking a bar code on the corresponding test tube, wherein the bar code comprises patient information, acquisition date, inspection items and the like; (3) the blood sample test tubes collected on the same day or a certain period are intensively sent to a clinical laboratory, manual classification is carried out by personnel in the clinical laboratory, and detection of corresponding items is carried out after the classification of the test tubes is finished. At present, test tubes used in clinical laboratories mainly have two specifications, the length of the test tube of one specification is 10CM, the length of the test tube of the other specification is 7CM, and the diameters of the test tubes of the two specifications are the same. Each test tube of a certain length is distinguished according to the color of different test tube caps, for example: the long yellow indicates biochemical and immunological items; the evergreen indicates blood ammonia and blood disease typing; the long red represents biochemical and immunological items; long purple indicates blood type; short black indicates blood sedimentation; short blue indicates blood coagulation; shortness of purple indicates blood convention, etc. Wherein, long yellow represents the test tube with specification of 10CM and yellow cap, short blue represents the test tube with specification of 7CM and blue cap, and so on. Because the test tubes are different in length and color and represent different inspection items, the test tubes with different lengths and colors are not accurately classified by related equipment in the inspection process at present, and only manual classification is required, so that the classification efficiency is low. In addition, when a medical worker collects a blood sample, it is required to ensure that a test item on a bar code corresponds to a designated test tube, for example, a patient performs blood type item detection, the bar code can indicate that the test item is blood type, the collected blood sample is normally placed in a long purple test tube, and due to negligence of the medical worker, the collected blood sample is placed in a short blue test tube, so that in a clinical laboratory, the test tube is manually classified into a blood coagulation test item, the test item does not correspond to the test item marked on the bar code, and finally, the test result is not the test result expected by a doctor. At present, the test tube classification is only carried out manually, the error information cannot be corrected, and finally, the result error is caused.

Detailed Description

The invention is described in further detail below with reference to the following figures and detailed description:

example 1

As shown in fig. 1, an embodiment of the present invention relates to a test tube sorting apparatus, which includes the following components:

As shown in fig. 2, the drop hopper 1 is located above the rear side of the first test tube transport mechanism 2. The blanking hopper 1 is used as an inlet of the test tube sorting device, and batch test tubes (corresponding to a plurality of inspection items) obtained by collection can be intensively put into the blanking hopper 1.

The first test tube conveying mechanism 2 functions to convey the test tubes onto the first sorting mechanism 3.

The first test tube conveying mechanism in this embodiment is preferably a belt conveying mechanism, and the structure thereof is shown in fig. 2 and 3. The first test tube conveying mechanism 2 includes a first conveying belt 10, a first pulley 11, and a first belt side shutter 12.

A plurality of first test tube partitions, for example, first test tube partitions 13, are provided on the surface of the first conveyor belt 10.

The first test tube partitions 13 are arranged perpendicular to the conveying surface (i.e., the surface of the first conveyor belt 10) at regular intervals. The laying direction of the first test tube partition plate 13 is perpendicular to the test tube conveying direction of the first test tube conveying mechanism.

The test tube conveying direction of the first test tube conveying mechanism is defined as the front-rear direction, and the arrangement direction of the first test tube partition plates 13 is the left-right direction. The first test tube divider 13 serves to space apart the test tubes on the surface of the first conveyor belt 10.

It is required that only one test tube can be placed between two adjacent first test tube partition plates 13, and for this reason, the distance between two first test tube partition plates 13 needs to be designed to be larger than 1 time of the diameter size of the test tube and smaller than 1.2 times of the diameter of the test tube.

The height of first test tube baffle 13 as long as guarantee can with the test tube interception between arbitrary two first test tube baffle 13 can.

The first belt pulley 11 has two parts, one is a driving wheel and is provided with a first driving motor 14, the other is a driven wheel, the first driving motor 14 is connected with an upper computer (not shown) through a cable, and the upper computer controls the action of the first driving motor 14.

A first conveyor belt 10 is disposed around and between two first pulleys 11.

The first belt-side plate fences 12 are two in number and are located on opposite sides of the first conveyor belt, e.g., left and right in fig. 3.

The width of the first conveyor belt 10 is only slightly larger than the length of the first test tube 15, and may be, for example, 10.5-11.5 cm. Wherein the first test tube 15 is a test tube with a length of 10cm, and the second test tube 16 is a test tube with a length of 7 cm.

Above design can guarantee that each test tube is put neatly when getting into first sorting mechanism 3, does benefit to follow-up letter sorting. As can be seen from FIG. 3, the test tubes are placed in the left-right direction, and some of the test tube caps are close to the left and some are close to the right.

When the test tube passes through, no matter the head of test tube is towards left or right, can both guarantee that one of them colour discernment sensor 34 can gather the colour of test tube cap, then from the position that corresponds sort out this test tube can.

Taking one of the test tube sorting units 27 as an example:

if the test tube sorting unit 27 needs to sort the test tubes with blue caps, the two color recognition sensors 34 in the test tube sorting unit 27 respectively collect the colors of the passing test tubes, and then upload the collected results.

The upper computer judges that the color is not the color which needs to be sorted by the current test tube sorting unit 27, and then the upper computer does not process the color, and the test tubes are continuously conveyed forwards on the second sorting conveying belt 28.

When a test tube of the blue cap is picked up by the test tube sorting unit 27, it is sorted out from the second sorting conveyor belt 28.

Since the present embodiment employs two color recognition sensors, when the color recognition sensor 34 located at the left recognizes the blue cap, it indicates that the head of the test tube is facing left, and conversely, indicates that the head of the test tube is facing right.

By designing the two color recognition sensors 34, the placement direction of the test tubes on the second sorting conveyor belt 28 can be determined, and the placement direction of the test tubes can be unified for the next step.

The arrangement directions of the first push rod mechanism and the first test tube temporary storage rack are the same as those of the color sensor (the first push rod mechanism and the first test tube temporary storage rack are arranged in the left-right direction). Wherein the first pusher mechanism and the first temporary test tube storage rack 35 are located at a set of opposite notches 33.

The first pusher mechanism is configured to push the test tubes on the second sorting conveyor belt 28 onto the first test tube buffer rack 35. The process is started after the color recognition of the test tube is completed.

The piston rod of the first driving cylinder 36 is connected to the push rod 37, and the cylinder body of the first driving cylinder 36 is fixed. The first drive cylinder 36 is an electromagnetically controlled cylinder.

The first driving cylinder 36 is connected to an upper computer through a wire, and the operation of the first driving cylinder 36 is controlled by the upper computer.

Push rod 37 and first test tube frame 35 of keeping in are located the left and right sides of second sorting conveyer belt 28 respectively, and push rod 37 aims at first test tube frame 35 of keeping in, conveniently with the test tube propelling movement to first test tube frame 35 of keeping in.

Through designing a plurality of test tube letter sorting units 27, be convenient for carry out accurate classification with the test tube of a plurality of different colours (test tube cap) of same length, the test tube after the classification is from corresponding breach letter sorting respectively and transfer to first test tube and keep in on the frame 35.

First test tube is kept in frame 35 and is a flat board, sets up baffle a, b, c of take the altitude at the border of the three side of this flat board simultaneously, prevents that the test tube from keeping in frame 35 landing from first test tube, as shown in fig. 6.

The height of the baffle plates a, b and c is designed so as not to influence the falling of the test tube when the first test tube temporary storage rack 35 rotates.

When the test tube reaches the first test tube temporary storage rack 35, the placing direction of the test tube is determined, or the head (test tube cap) of the test tube faces to the left or the head of the test tube faces to the right, and then the head directions of the test tubes need to be unified.

The purpose of unifying the placing direction of the test tubes is to conveniently identify the test tubes in the code scanning identification process by a scanner.

A test tube direction adjustment mechanism 38 is installed at each first test tube temporary storage rack 35. The test tube direction adjusting mechanism 38 is used to adjust the placement direction of test tubes of which the length and color are classified.

When the adjusted test tube reaches the second test tube conveying mechanism, the direction of the test tube faces towards the left side or towards the right side (which is preset).

As shown in fig. 7, the test tube direction adjustment mechanism 38 includes a first test tube temporary storage rack inclination adjustment mechanism 39 and two test tube falling paths, such as a falling path 40a and a falling path 41 b.

When a test tube is positioned on the test tube rotary drive mechanism, the barcode scanner 51 is aligned with the barcode area of the test tube.

The barcode scanner 51 in this embodiment is a bar scanner for identifying information in a barcode on the outer sidewall of the test tube.

The effect of the test tube rotation driving mechanism is that when the test tube is transferred between the first rubber roller 53 and the second rubber roller 54, the first rubber roller 53 rotates to drive the test tube to rotate.

During rotation, the bar code on the outside wall of the test tube is recognized by the bar code reader 51.

Two rollers are the aim at increase frictional force that rubber materials made more than the design, guarantee the rotatory effect of test tube, and limit baffle 55 then guarantees that the test tube is in between first rubber roller 53 and the second rubber roller 54.

Example 2

As shown in fig. 12, embodiment 2 of the present invention describes a test tube sorting method, which is based on the test tube sorting apparatus in embodiment 1, and by which accurate sorting of test tubes can be automatically realized and checking of test items can be simultaneously realized.

The test tube classification method in embodiment 2 of the present invention has the following general working process:

the batch of test tubes are firstly conveyed to a first sorting mechanism 3 by a blanking hopper 1 through a first test tube conveying mechanism 2, and the test tubes are sorted according to the lengths of the test tubes; the test tubes then enter the second sorting mechanism 4, where they are sorted according to the colour of the test tube caps.

The above steps complete the classification of test tube length and color.

The test tubes after being classified need to enter the test tube direction adjusting mechanism 5 for direction adjustment.

The test tube after the direction adjustment is sent to a scanning, identifying and sorting mechanism 7 through a second test tube conveying mechanism 6, and the checking of the test items corresponding to the test tube and the test items marked on the bar codes is completed;

if the proofreading is successful, the test tubes are sent to the test tube temporary storage box 8, and if the proofreading is failed, the test tubes are sent to the test tube rejecting box 9.

More specifically, the procedure of the tube sorting method in this embodiment is as follows, as shown in fig. 12.

S1, firstly, a batch of test tubes collected every day or in a certain time period are collectively placed into a blanking hopper 1.

The test tube dropped from the outlet of the drop hopper 1 is dropped on the first test tube conveying mechanism 2. Driven by the first driving motor 14, the test tubes are conveyed along the first conveying belt 10 from back to front and are conveyed onto the first sorting mechanism 3.

S2, the first sorting mechanism 3 sorts the test tubes according to the lengths of the test tubes, and the specific process is as follows:

the test tubes are sequentially conveyed along the first sorting conveyor belt 19 from back to front, the first test tube 15 does not fall down during the conveyance, and the second test tube 16 falls down to the top of the inclined surface 25 of the rail from the test tube falling area 24 and falls down from the top.

By this, the preliminary classification of the test tubes is done according to the length of the test tubes.

S3, the first test tube 15 and the second test tube 16 respectively enter a second sorting mechanism 4, and the test tubes are further sorted according to colors. The second sorting mechanism 4 sorts the test tubes as follows:

the first test tube 15 and the second test tube 16 are sequentially conveyed from back to front along the corresponding second sorting conveyor belt 28, and each test tube sorting unit 27 sorts only one test tube of a corresponding color during the test tube conveying process.

The specific process of tube sorting is as follows:

the two color recognition sensors 34 in each test tube sorting unit 27 simultaneously recognize the color of the test tube caps of the passing test tubes, and only one color recognition sensor collects the color of the test tube caps.

The color identification sensor I which acquires the color uploads an acquisition result to the upper computer; the test tube of this colour is judged to the host computer whether needs the test tube of letter sorting for current test tube letter sorting unit:

if the test tube is placed in the test tube placing direction, the test tube sorting unit 27 sorts the test tubes out, and the upper computer records the position of the color recognition sensor I, which can be used as a basis for determining the placing direction of the test tubes later.

If not, the test tubes continue to be conveyed on the second sorting conveyor belt 28 in sequence from back to front and are identified by the next test tube sorting unit 27, and the above sorting process is repeated until they are sorted out by the respective test tube sorting unit 27.

Wherein, the concrete process that test tube sorting unit 27 sorts the test tube is:

after confirming that the test tube of a certain colour is the test tube that the present test tube sorting unit needs to sort, send the instruction by the host computer, first push rod mechanism with this test tube from second letter sorting conveyer belt 28 go up the propelling movement to first test tube on the frame 35 of keeping in.

By this, the classification of the test tubes is further completed according to the color of the test tubes.

S4, the host computer judges the orientation of putting of test tube on the first test tube temporary storage rack 35 according to the colour recognition sensor I's of record position, confirms simultaneously whether the orientation of putting of this test tube needs the adjustment:

if the direction adjustment is needed, the first test tube temporary storage rack 35 is inclined towards the test tube falling channel of the internal shift lever, i.e. the test tube falling channel 40b, the test tube completes the reverse adjustment in the falling process, and the adjustment angle is 180 degrees.

If the direction adjustment is not necessary, the first test tube temporary storage rack 35 is inclined toward the test tube falling path in which the stopper is not provided, that is, the test tube falling path 40a, and the test tube is directly dropped in the test tube falling path 40 a.

S5. the test tubes falling from the test

tube falling path

40a or 40b are all dropped on the second test tube conveying mechanism 6. Under the drive of the second drive motor 49, the test tube is conveyed along the second conveying belt 46 from back to front to the scanning recognition sorting mechanism 7.

The checking of the inspection items is completed in the scanning, identifying and sorting mechanism 7, and the specific process is as follows:

under test tube rotary drive mechanism's effect, the test tube can be at vertical face internal rotation, and rotatory in-process, bar code district that sign indicating number ware 51 aimed at the test tube sweeps the sign indicating number, then will sweep the sign indicating number result and upload the host computer.

Under the control of the upper computer, the second push rod mechanism pushes the test tube to the second test tube temporary storage rack 52.

After receiving the uploaded bar code information, the upper computer can proofread the inspection item information contained in the bar code and the inspection item corresponding to the current test tube to obtain two results of proof reading success or proof reading failure.

If the proofreading is successful, the second test tube temporary storage rack 52 inclines towards the test tube temporary storage box 8 under the control of the upper computer, and the test tube falls into the test tube temporary storage box; if the proofreading fails, the second test tube is kept in the frame and is rejected the case slope to the test tube, and the test tube falls into the test tube and rejects case 9.

The invention can effectively avoid the error of the inspection result caused by the fact that the inspection item information contained in the bar code does not correspond to the inspection item corresponding to the test tube, and when the condition occurs, the inspection personnel can feed back the information to the front-end acquisition personnel in time.

The invention realizes the accurate classification of the test tubes and has high automation degree. The invention also realizes the automatic proofreading of the test items corresponding to the test tubes and the test items contained in the bar codes, is convenient to find in time and avoids the error of the test result.

It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
