Description
Technical field
The present invention relates to a kind of specimen cup, and in particular to the specimen cup that a kind of cellanalyzer uses.
Background technology
The size of leucocyte can be classified according to its volume size within the specific limits in normal human blood, at present
Three classification blood cell analyzers (also referred to as " electrical impedance method " or " Kurt method ") carry out blood count using " orifice method "
And stereometry, its Cleaning Principle are that haemocyte will produce resistance variations when passing through aperture, realize hemocytometer accordingly
Several automations.
The critical piece of three classification blood cell analyzers is aperture plate, also referred to as sensor (Transducer).Aperture
Plate is inserted into the cell suspension of isotonic electrolyte solution dilution, and dilution is filled with the inside of aperture plate, and has an interior electrode, outside
There is an external electrode side.The conduction property of cell is lower than isotonic dilution, after electrode switches on power, positioned at aperture both sides
Electrode between produce stable electric current, dilution is flowed by aperture.The conductibility of cell is less than dilution, when cell pass through it is small
Kong Shi, resistance increase, causes voltage change in moment and a pulse signal occurs, be referred to as passing through arteries and veins in aperture induction zone
Punching.Voltage change caused by cell volume is bigger is bigger, caused higher by pulse amplitude.When electric current I and impedance Z are stable
, cell volume can be determined by the measurement to impulse magnitude, distinguish different types of cell, the number of recording impulse
The result of cell count can be obtained.
The sample cup structure that existing three classification cellanalyzer uses is as shown in figure 1, including two chambers of cup and rear chamber
Body, cup electrode and rear chamber electrode being respectively arranged with cup and rear chamber, the cup is connected with rear chamber by counting hole, after
A liquid outlet and an inlet are provided with room housing.As shown in Figure 1, the rear chamber of existing specimen cup is a cavity, is adopted
It is the liquid stream cleaning way of one-in-and-one-out.The applicant in experiments it is found that, the specimen cup of existing structure exist it is following not
Foot：
(1) because rear chamber is single cavity geometry, when (including particle (i.e. cell) and liquid) passes through counting hole in sample
When, the easily change in rear chamber resistance between electrode before and after bore region turbulization and then influence is counted, cause count results not
Accurately.
(2) there is corner in rear chamber, be not easy to clean up in the short time, it is possible to subsequent counter can be had an impact.
The content of the invention
The technical problem to be solved in the present invention is to provide the specimen cup that a kind of cellanalyzer uses, the specimen cup passes through
Dividing plate is set in rear chamber and structure of two liquid outlets simultaneously with soft pipe connection is set, effectively controls turbulent flow to close in rear chamber
The influence of resistance variations between counting hole area electrodes, improve and count accuracy rate.
The specimen cup that cellanalyzer of the present invention uses, including two cavitys of cup and rear chamber, in cup and
Cup electrode and rear chamber electrode are respectively arranged with rear chamber, the cup is connected with rear chamber by counting hole, wherein：
The rear chamber is formed after being connected by the rear chamber protecgulum with the first cavity with the rear chamber bonnet with the second cavity,
Dividing plate is provided between rear chamber protecgulum and rear chamber bonnet, there is the passage passed through for liquid, the mouth of the feeder connection on the dividing plate
Footpath is less than the bore of its outlet, and the center line of the passage overlaps with the center line of counting hole；
The first inlet and the first liquid outlet are respectively arranged with rear chamber protecgulum, is covered after rear chamber and is provided with second and enters
Liquid mouth and the second liquid outlet, the first described inlet and the second inlet are connected by flexible pipe and the road for the equipment for providing negative pressure
Logical, described the first liquid outlet and the second liquid outlet passes through flexible pipe and the pipeline connection for providing cleaning fluid.
The present invention is divided into two cavitys connected by passage, when logical negative pressure counts, turbulent flow by setting dividing plate, by rear chamber
The change of rear chamber first half (i.e. rear chamber is close to counting bore region) resistance between electrode can not be influenceed at once because of spacers block；Separately
On the one hand, two liquid outlets are set, and with flexible pipe by the path connected of they and the equipment for providing negative pressure, so as to manufacture liquid stream
Time difference, control when once counting completion, sample (including cell and liquid) is just back to rear chamber first half；Two means
The influence for achieving effective control turbulent flow to resistance variations close counting hole area electrodes in rear chamber is combined, improves and counts accurately
Rate.
In above-mentioned technical proposal, the passage on the dividing plate is preferably the loudspeaker gradually increased in porch to exit bore
Shape, it so can effectively prevent the first half (i.e. rear chamber close to count bore region) in rear chamber by the cell of counting hole
Diffusion.
In above-mentioned technical proposal, the profile of dividing plate can be arranged as required to, and such as can be square or other irregular shapes
Shape, but preferably by baffle design into the horn shape gradually increased from porch to exit external diameter, so can be further
Reduce the corner for being not easy to be flushed in rear chamber so that it can clean cleaner within the relatively short time in cleaning, so as to
Instrument can be shortened and count the cycle, improve detection efficiency.
In above-mentioned technical proposal, the first inlet and the first liquid outlet are preferably respectively arranged at opposed on rear chamber protecgulum
Position, and the second inlet and the second liquid outlet cover opposed position after being then preferably respectively arranged at rear chamber, so may be used
To be more beneficial for cleaning rear chamber.
Equally consider from the corner that is not easy to be flushed to is reduced in rear chamber, rear chamber electrode is preferably arranged at rear chamber protecgulum
On the inwall of upper first cavity, and it will be covered after rear chamber between the bottom surface of the second cavity and its side using cambered surface connection or inclined-plane
Connection.Each face of the first cavity is formed on the rear chamber protecgulum in connection it is also preferred that being connected using cambered surface connection or inclined-plane.
In above-mentioned technical proposal, the rear chamber protecgulum and rear chamber bonnet are usually to be detachably connected, usually using screw
Realize the connection of rear chamber protecgulum, dividing plate and rear chamber bonnet three.
Compared with prior art, the method have the characteristics that：
1st, by setting dividing plate, by rear chamber be divided into two by passage connect cavitys, when logical negative pressure counts, turbulent flow because every
Plate stops and can not influence the change of rear chamber first half (i.e. rear chamber is close to counting bore region) resistance between electrode at once；The opposing party
Face, sets two liquid outlets, and with flexible pipe by the path connected of they and the equipment for providing negative pressure, so as to manufacture the time of liquid stream
Difference, control when once counting completion, sample (including cell and liquid) is just back to rear chamber first half；Two means are mutually tied
The influence for achieving effective control turbulent flow to resistance variations close counting hole area electrodes in rear chamber is closed, improves and counts accuracy rate.
2nd, using the rinse mode to go with each other all the time, effectively cleaning performance of the lifting to rear chamber.
