Description

Leucorrhea sample pretreatment device based on test tube with specific structure

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a leucorrhea specimen pretreatment device based on a test tube with a specific structure.

Background

At present, the pretreatment form of the leucorrhea specimen is generally divided into two types, one is a manual form, and the other is an automatic form. The manual form is that the manual work is put the cotton swab sample to the soft test tube of PP, and the manual work is injected into the diluent, and the hand is held between the fingers the cotton swab and is carried out the sample elution mixing, then will dilute the dissolved liquid sample and pour into the short test tube that the machine can handle in, place and send a kind position at the instrument, remove to detect the position and carry out the sample processing. The automatic mode is to add a pretreatment structure, realize the automation of sample dilute, shake even, then break the cotton swab, abandon the cotton swab pole, keep the cotton swab head in the sample liquid, send to the testing position and carry out the sampling processing.

The problems existing in the existing artificial form are as follows: firstly, the sample solution is easy to cause cross infection due to manual contact. Secondly, the kneading process is performed by hands, the manual experience and occupation operation of workers are all relied on, and the situation of incomplete mixing is easy to occur due to the emotion of the workers and other reasons in the mixing process. Thirdly, in case of liquid transfer, the liquid may be poured out during the pouring process, which results in contamination of the working site.

The problems of the existing automatic form are as follows: most of the existing devices in the market adopt cotton swab sampling devices with the same opening, and the device needs to be punctured or opened when diluent is added; the cotton swab is stirred and then the sample is sucked, and the sample is automatically opened once, so that the pretreatment equipment needs a complex cover opening mechanism, the cost is increased, and the reliability of the instrument is reduced.

Detailed Description

The technical scheme of the invention is further explained by combining the drawings and the embodiment as follows:

referring to fig. 1 to 5, the present invention provides a leucorrhea specimen pretreatment apparatus based on a test tube with a specific structure, comprising: a cuvette 1, said cuvette 1 comprising: test tube lid 11, test tube body 12 and cotton swab 13, test tube lid 11 is connected the top of the test tube 12 body, cotton swab 13 runs through test tube lid 11 and stretch into in the test tube body 12, test tube lid 11 has set gradually cotton swab stirring mouth 111 and rifle head sample connection 112 from a left side right side, be provided with direction interior limit 113 between cotton swab stirring mouth 111 and the rifle head sample connection 112, cotton swab stirring mouth 111 is kept away from the one end of rifle head sample connection 112 is provided with spacing limit 114, test tube body 12 has set gradually cotton swab mixing cavity 123, sample liquid through cavity 121 and sample liquid sample cavity 122 from a left side right side, cotton swab mixing cavity 123, sample liquid through cavity 121 and sample liquid sample cavity 122 communicate each other. The limiting edge 114 is clamped with the flange of the test tube rack 4, so that the situation that the test tube cover 11 is taken out of the test tube rack to cause uncontrollable position when the sliding block moves upwards is prevented.

As a preferred embodiment, the upper end of the cotton swab stirring port 111 is a straight small opening, the lower end of the cotton swab stirring port is a tapered opening, and the lance tip sampling port 112 is located at a lower position on the side of the cotton swab stirring port 111. The distance from the sampling port 112 of the gun head to the bottom surface of the test tube 1 is short, so that the time required for the up-and-down movement of the device during sampling can be reduced.

In a preferred embodiment, the lower extent of the guiding inner edge 113 extends beyond the bottom end of the cuvette lid 11. The inner guide edge 113 is used for limiting the downward movement direction of the gun head and improving the stability of the gun head in the downward movement sampling process.

As a preferred embodiment, still include preceding processing mechanism, preceding processing mechanism includes the workstation, be provided with sample presentation equipment 3 on the workstation, be provided with test-tube rack 4 on the sample presentation equipment 3, test tube 1 is arranged in the test-tube rack 4, the top of workstation is provided with sampling arm 2. The sampling arm 2 comprises: the automatic feeding device comprises a frame, the top of frame is provided with lead screw motor 23, the output end threaded connection of lead screw motor 23 has the slider, fixedly connected with rotating electrical machines 22 on the slider, rotating electrical machines 22's output fixedly connected with mixing rotating head 21, still be provided with dilution needle 24 on the slider. The inner wall of the rack is also provided with a guide rail, and the guide rail is in sliding fit with the sliding block. The middle part of workstation is identification position, identification position is provided with sensor 31 and bar code scanner 32, sensor 31 is used for detecting whether there is test tube 1 to pass through, bar code scanner 32 is used for reading the bar code numerical value on the test tube 1.

The working principle of the invention is as follows:

through the propelling movement of sample conveying equipment 3, make test tube 1 move to the discernment station along with test-tube rack 4, sensor 31 judges whether to have test tube 1 on the station after through optical detection. When the test tube 1 is determined, the sampling arm 2 starts to move to the upper part of the test tube 1 for the next operation.

The screw motor 23 starts to drive the slider to move downwards, and the cotton swab rod with the set length is broken in the cotton swab stirring port 111 of the test tube 1 due to the fact that the blending rotating head 21 faces the cotton swab stirring port 111 of the test tube 1. When the blending rotating head 21 is opposite to the cotton swab head, a dilution needle 24 is obliquely arranged on the sliding block, the dilution needle 24 is right opposite to the sampling port 112 of the gun head of the test tube 1 at the moment, the upper end of the dilution needle 24 is connected with a peristaltic pump through a pipe, and the other end of the peristaltic pump is connected with a dilution liquid bottle. And the mixing rotating head 21 hole has screens mechanism and prevents the rotation bottom surface, and the hole and the cotton swab stick pole of this moment mixing rotating head 21 are connected, then start rotating electrical machines 22, and cotton swab 13 then can follow the quick rotation of mixing rotating head 21.

The cotton head of cotton swab 13 lower part is rotatory in being taken the diluent, and the diluent of test tube 1 bottom then can be stirred in the fast revolution of cotton swab 13, and test tube 1 bottom is divided into two chambeies, and the shape is peculiar, so the diluent that cotton swab 13 stirred can not do circular motion, at this moment will lead to the interior liquid turbulence of test tube 1 to incessantly wash the surface of cotton swab 13. Simultaneously cotton swab 13 is rotatory, incessantly with the contact of dilution liquid, and the sample drops from cotton swab 13 among the contact process to in the dilution of mixing in test tube 1, form and detect required appearance liquid.

After the set time of the blending, the screw motor 23 of the sampling arm 2 drives the slider to move upwards, and the swab 13 is separated from the blending rotating head 21. And (5) uniformly mixing.
