Background technology

[02] tumor screening system of the present invention use automatic unit with cell from contain separate with the bottle of the solution of mixing with cells and with cell harvesting on microslide, and of the present inventionly be used for receiving flask that liquid based cytology detects and be used for storing simultaneously the solution that contains cell and solution is poured out tumor screening system.

[03] specifically, being used for receiving flask that liquid based cytology detects is used to collect cervical cell and the cell collected is mixed with the solution that is used to detect cell.

[04] is used for that cell is stored in the receiving flask that solution and pair cell detect and is called the solution bottle hereinafter.

[05] Figure 17 is the synoptic diagram of traditional solution bottle of local specification and traditional tumor screening system.As shown in figure 17, traditional solution bottle 70 contains the cell of collection, and uses closed with covers.Traditional solution bottle 70 by the user hand or use other devices to shake so that cell mixes with solution in the solution bottle 70.Solution bottle 70 only is used for storage solutions.Therefore, traditional tumor screening system comprises the independent container 80 that is used to receive solution.That is to say that traditional tumor screening system also needs container 80 except needs solution bottle 70.

[06] because the container 80 of traditional tumour screening system has the upper end face of opening, so the solution in the container 80 can ingress of air.Columniform main body 83 supports the filtrator 86 that collection membrane 87 is installed, and by shift-in and the piston 90 that shifts out main body 83 solution is drawn onto traditional tumor screening system from container 80.Main body 83 and container 80 are by being threaded.

[07] is used for being independent of traditional tumor screening system and installing with being bonded at solution bottle that cell on the brush is distributed to solution.Under the condition that by the agitation of solutions bottle cell fully is distributed in the solution, the solution in the solution bottle is poured in the container, the suction means draw solution that contacts with the lower surface of filtrator will adhere on the microslide by the cell that filtrator leaches then.

[08] with container and body portion from so that collection membrane is shifted near microslide, the mixed solution that remaines in the container is poured out because of gravity, thereby can not be repeated to use.

[09] and, be that hand by the user is carried out because cell is transferred to microslide from the solution bottle, so transitional cell need consume the long time.And, pollutant or impurity may be transferred on the microslide from user's hand, thereby reduced the correctness that cytology detects.

[10] after solution being poured in the container and drawing the solution of the requirement in the container by suction means, all the other solution in the container are exposed in the air.Therefore, when reusing all the other solution, can't guarantee the correctness that detects.

[11] with the lower part of filtrator and container from the time, all the other solution in the container are poured out and contaminated system, thereby cause hygienic issues.

[12] brush that is used for the liquid based cytology detection of cervical carcinoma of the present invention helps the uterus collecting cell from the women.

[13] most of women's disease and women's reproductive organs (for example, uterus) is relevant.

[14] wherein a kind of modal female diseases is a cervical carcinoma, and this is a kind of tumour.Cervical carcinoma is a kind of well-known relatively pathogenetic tumour that has, and produces by Human infectious warts virus (HPV), and wherein, Human infectious warts virus (HPV) is a kind of venereal disease.In the sexual intercourse process, when women's epithelial cell was subjected to the infection of HPV, DNA, the breeding of the DNA permeation cell of HPV nuclear also produced epithelial cancer.

[15] proposed the various methods whether cell is subjected to the HPV infection that are used to detect, learned the diagnosis smear method comprising cervical cell.Recently, use polymerase chain reaction (PCR) method to detect cell and whether be subjected to the HPV infection.PCR method is sensitive, the most correct screening method that is used for the early diagnosis of cervical carcinoma.

[16], need the cell of cell, the especially woman cervix uteri in collection women uterus in order to use PCR method.Proposed to have being used for of different shape from the brush of women uterus collecting cell.

[17] the early stage publication application of Korean Utility Model 1999-1000001 number (calling " list of references 1 " in the following text) discloses " being used to diagnose the cell harvesting structure of cervix diseases ".List of references 1 discloses " being used to collect the brush of cervical cell ", is inserted in women's the vagina and collects cervical cell.

[18] disclosed in the list of references 1 " being used to diagnose the cell harvesting structure of cervix diseases " comprise the adventitia collector unit and the inner membrance collector unit of separation, it is connected with the both sides of handle, thereby causes from the inconvenience of Cervical adventitia and inner membrance separate collection cell.

[19] and, the early stage publication application of Korea S 2004-82781 number (calling " list of references 2 " in the following text) discloses " being used to collect the device of cervical cell ".Disclosed in the list of references 2 " being used to collect the device of cervical cell " comprises main gatherer, auxiliary holding tank of being made by silicon and the joint with adjustable-length.

[20] advantage of disclosed in the list of references 2 " being used to collect the device of cervical cell " is, the length of device is adjustable, but its shortcoming is that cell harvesting only relies on the collection brush for preparing in first collector unit, thereby can not guarantee cell harvesting efficient.And, second collector unit extends from first collector unit along the direction vertical with the longitudinal direction of first collector unit, and can stimulate the inwall of woman vagina in the time of will " being used to collect the device of cervical cell " and inserting women's vagina, thereby cause patient's pain or damage vaginal walls.

[21] in order to use PCR method, generally the cell of collecting is stored in the container that cell fixation solution is housed.In list of references 1 and 2 disclosed construction and devices, because the hand by operating personnel or use other instruments (for example, anchor clamps) that collector unit is directly separated with brush, so collector unit may be subjected to foreign substance pollution.This can hinder correctly diagnoses the cell of collecting.

[22] assisted solution that is used for cytodiagnosis of the present invention comprises buffering agent, the cell of store collected under its condition in the cell that will collect remains on appointment pH scope; Alcohol, it is used to suppress the protein denaturation of cell, to keep the pathologic structure of cell; Drying retarder, it is used to prevent that the cell that stores from becoming dry between follow-up cell pathology detection period; And antiseptic, it is used to prevent that the cell that stores from rotting.

[23] assisted solution that is used for cytodiagnosis refers to be used to preserve the solution of the cell of collecting from human body, detects with the liquid based cytology of carrying out cell, thereby carries out the cell pathology diagnosis.Liquid based cytology detects and to be used to detect gynaecology's sample, for example cervical cell, and non-gynaecology sample, and for example saliva, body fluid and urine, and carry out the fine needle aspiration biopsy.In liquid based cytology detects, whether there is cancer cell in the cell of collecting by the cell inspection of using microscopic examination to collect.

[24] Figure 23 is the synoptic diagram of explanation conventional cell diagnosis.With reference to Figure 23, Pap smear has been used in traditional cytodiagnosis, wherein, cell is applied on the microslide, detects then.When being applied in cell on the microslide, the cell on the microslide is dry easily, and can not remove viscosity solution and red blood cell from cell, thereby causes the difficulty of reading diagnostic result.And, owing to only will use 10% of cell that brush collects from women's cervix to be applied on the microslide, and the cell of all the other collections is thrown away, therefore possibly can't be with to diagnosis and the cell of wanting of overstating is applied on the microslide.Therefore, traditional cytodiagnosis has low reliability.

[25] in order to address the above problem, developed the liquid based cytology detection now, wherein, the cell of collecting is kept in the assisted solution, to carry out the cell pathology diagnosis of cell.In liquid based cytology detects, use the brush collecting cell, and it is stored in the assisted solution, and in case of necessity, judge by detecting whether the cell that is stored in the assisted solution is unusual.Figure 24 is the view that is used for the correctness of more traditional cytodiagnosis and liquid based cytology detection.With reference to Figure 24, according to traditional cytodiagnosis, cell sample also anisotropically is distributed on the microslide, thereby diagnostic result changes according to examined sample portion.On the other hand, detect according to liquid based cytology, the sample cell is distributed on the microslide equably, thereby has improved diagnostic accuracy.

[26] detect in order to carry out above liquid based cytology, need be used to preserve the solution of the cell of collecting.Traditionally, liquid based cytology detects needs 95% ethanol.95% ethanol can't be preserved cell (cell can be preserved nearly 1 week) for a long time, and can't remove red blood cell from cell, thereby needs independent process that red blood cell is removed from cell.And the nuclear that is stored in the cell in 95% ethanol can be out of shape, thereby can't extract DNA from cell.And 95% ethanol has high alcohol content, and inflammable, thereby can cause the danger of fire.

[27] in order to address the above problem, United States Patent (USP) the 5th, 256 discloses a kind of cell No. 571 to preserve solution, and it comprises soluble alcohol, anti-caking agent and buffering agent.Preserve in the solution at cell, alcohol is to be selected from a kind of in the group that is made up of ethanol, isopropyl alcohol and methyl alcohol, anti-caking agent is to be selected from a kind of in the group that is made up of ethylenediamine tetraacetic acid and salt thereof, and buffering agent is to be selected from a kind of in the group that is made up of ethylenediamine tetraacetic acid, edetate, citric acid and citrate.But, account for 45-55 part by weight owing to be used for fixing the alcohol amount of cell, preferably account for 50 parts by weight, so the 5th, 256, No. 571 disclosed cells preservation solution of United States Patent (USP) remain inflammable.Moreover cell is preserved solution and is had low red blood cell clearance, cell can only be preserved the relatively short time (about 3 months), thereby make from cell extraction DNA very difficult.

[141] process of using solution bottle of the present invention cell to be mixed and by tumor screening system of the present invention cell transferred to from the solution bottle microslide with solution hereinafter will be described.

[142] at first, carry out the parts of collecting cell and put into the step that the solution bottle mixes with solution with the cell that will collect.

[143] user is separated with shell 1 by the nethike embrane installation unit 30 that will be connected with lid 40 with hand rotation nethike embrane installation unit 30, and will be used for soaking the solution injection shell 1 of cell.Then, user's parts of collecting cell puts into shell 1, and nethike embrane installation unit 30 is connected to shell 1.[144] second, solution bottle with parts of collecting cell and the cell that will collect are transferred to microslide from the solution bottle step carry out to be installed.

[145] open the receiving unit 105 that mixed solution forms unit 100, and will have that the solution bottle of the parts of collecting cell is installed in the receiving unit 105.More particularly, the bottom of shell 1 is connected to the projection that is formed at the swivel plate in the receiving unit 105, and the receiving unit 105 that will have a solution bottle pushes and stirs in the chamber 102.Use control module to make swivel plate rotation preset time with predetermined speed.During rotation solution bottle, the stirring projection 5 of the agitation part 4 of shell 1 and the impeller 24 of piston 20 stir solution in the solution bottle, and mix with the isolation of components of cell and collecting cell and with solution in the solution bottle.

[146] be reduced under the condition of distance of appointment by pushing lowest block 115 with solution bottle operating unit 110, (cell and solution are in wherein mixing mutually fully) is inserted in the space between two-

stage piece

112 and 113 with the solution bottle, and when the power of pushing lowest block 115 is eliminated, restoring force by spring promotes lowest block 115, and under the condition that the nethike embrane installation unit 30 of solution bottle is blocked by the cavity of lowest block 115, lowest block 115 upwards pushes away the solution bottle, thereby the solution bottle is fixed on the solution bottle operating unit 110.When the pneumatic cylinder 132 of operated piston operating unit 130 when reducing cylinder rod 134 under these conditions, the branch offset hitch 135 that is formed at cylinder rod part 27 lower ends is snapped into the through hole of the bar portion 27 of piston 20.Therefore, the piston 20 of solution bottle under the condition that the solution bottle is fixed in solution bottle operating unit 110 and the connection between the piston operation unit 130 have been finished.

[147] then, the filtrator 50 that skids off from the filtrator loader of the clamp of filter operation unit 150 and it is transferred to the position above the suction unit 170 and stops.

[148] then, when the movable part 142 of the unit 140 of uncapping moved forward, lid spinner 145 was positioned at below the lid 40 of solution bottle.Then, the pneumatic cylinder 120 of working solution bottle operating unit 110 during with reduction movable block 118, makes overall fixed reduce in the two-stage piece 112 and 113 of movable block 118, and the solution bottle is also reduced.Here, the projection 146 of lid spinner 145 is inserted in the connector patchhole 42 of lid 40 of solution bottle, and when controlling motor with swivelling cover spinner 145, being threaded between relief cap 40 and the nethike embrane installation unit 30, so that lid 40 is separated with nethike embrane installation unit 30, and operation pneumatic cylinder 120, to promote the movable block 118 of solution bottle operating unit 110, the distance that promotes is corresponding to the height of lid 40, thereby makes the lid 40 can smooth opening.When opening of combined cover 40 and together the pneumatic cylinder 132 of operated piston operating unit 130 is when promoting cylinder rod 134, the piston 20 that lifting links to each other with the end of cylinder rod 134, with the internal pressure of the shell 1 that reduces the solution bottle, thereby prevent that solution from pouring out from the solution bottle.The movable part 142 (top placement separate lid 40) of unit 140 of uncapping moves backward.

[149] under the condition of the lid 40 of opening the solution bottle during pneumatic cylinder 120 of working solution bottle operating unit 110, reduce movable block 118, and the joint flange on the upper surface of filtrator 50 54 is connected to the outer wall 34 of nethike embrane installation unit 30 and the space between the inner connecting wall 35 by interference engagement, the pneumatic cylinder of operating suction unit 170 simultaneously is connected to the cylindrical connection groove 58 that the lower surface of filtrator 50 forms by interference engagement with the interference engagement part 174 on the upper surface of filtrator coupling part 172 when promoting the movable block of suction unit 170.Therefore, under sealing state, solution bottle, filtrator 50 and suction unit 170 are coupled together.Because filtrator 50 by the fixture support of filter operation unit 150, therefore is connected to filtrator 50 with solution bottle and suction unit 170 simultaneously.

[150] then, when operation is with absorption instrument that filtrator coupling part 172 links to each other under the condition of solution-drain hole 187 sealings that the solution receiving tube support 185 that passes suction unit 170 forms, pressure in pressure in the filtrator coupling part 172 and the solution receiving tube 182 can reduce, and collection membrane 51 filtrations of filtrator 50 are drawn and passed through to mixed solution by nethike embrane 32 simultaneously.The flow of solution that does not have cell is to solution receiving tube 182.Draw the mixed solution amount that the instrument adjustment is drawn from the solution bottle by control.During from solution bottle discharging solution, the pneumatic cylinder 132 of inoperation piston operation unit 130, and piston 20 freely descends.

[151] then, when the pneumatic cylinder 120 of working solution bottle operating unit 110 with the pneumatic cylinder 132 that promotes movable block 118 and operated piston operating unit 130 when promoting the piston 20 of solution bottle, the solution bottle is positioned on the filtrator 50, and the pressure in the shell 1 can not reduce, thereby prevents that the mixed solution in the solution bottle from pouring out downwards.

[152] hereinafter, the unit 140 of uncapping moves forward under the condition that promotes the solution bottle once more, and the execution process opposite with the process of uncap 40, thereby with lid 40 lock solution bottles.

[153] when the pneumatic cylinder 132 of operated piston operating unit 130 cylinder rod 134 is risen to away from the time with the solution bottle of lid 40 sealings, the piston 20 that lifting is blocked by the end of cylinder rod 134, and the connection groove 29 of the bar portion 27 of piston 20 is snapped into the fixed projection 10 in the guiding slit 8 of shell 1.Since under the state of snap-in, the top of the contact portion 22 contact shells 1 of piston 20, and when therefore promoting cylinder rod 134 continuously, the end of cylinder rod 134 separates slidably with the bar portion 27 of piston 20.Owing to pull out piston 20 from solution bottle, so the inside of shell 1 becomes vacuum state with lid 40 sealings.

[154] then, push downwards under the condition of lowest block 115 of solution bottle operating unit 110, the solution bottle is taken out from solution bottle operating unit 110.

[155] then, when under solution bottle and condition that filtrator 50 separates, operating the absorption instrument of suction unit 170 extraly, the bottom that solution on the collection membrane 51 of filtrator 50 is drawn to system will be remained in.

[156] then, the pneumatic cylinder 165 that operation is connected with movable part 161, with the microslide operating unit 160 on the moving filter device 50, and the pneumatic cylinder that is connected with microslide mounting portion 167 of operation, so that microslide mounting portion 167 is reduced to filtrator 50, thereby make the collection membrane 51 of the contacted filter 50 of microslide.When flatly moving described movable part 161 under the condition of the contacted filter 50 of microslide, microslide repeatedly contacts collection membrane 51.

[157] microslide receives cells from the collection membrane 51 of filtrator 50, and transfer to alcohol receiving element 200 above.Then, during with rotating part 163 rotation an angle of 90 degrees, linear guide groove is vertically holded up, and microslide separates with guide groove and falls into alcohol receiving element 200.

[158] microslide that will be immersed in the alcohol takes out from alcohol receiving element 200, and is used to detect the cell on it.

[159] detect after, can reuse and be in the solution bottle that stores under the condition of vacuum state in the inside of shell 1.In this case, piston connects the snap-in between releasing unit 210 release plunger 20 and the shell 1.More particularly, insert operation pneumatic cylinder 216 under the condition in the space between first plane 9 with fixed projection 10 in guiding slit 8 of solution bottles at the solution bottle with the denation 212 that piston is connected releasing unit 210 in a certain position, and when pushing the solution bottle downwards, by the space between denation 212 expansions first plane 9, thereby the snap-in between release plunger 20 and the shell 1, and make piston 20 can be reduced to the solution bottle in the corresponding position of surplus solution amount.That is to say that piston 20 turns back to the state that moves freely with respect to the solution bottle.

[160] solution bottle of the present invention not only holds cell sample with acting on, cell is mixed and store the container of mixed solution with solution, and directly is installed on tumor screening system and discharges solution downwards.

[161] and, because solution bottle of the present invention has the stirring unit, therefore when rotation solution bottle, the solution in the stirring solution bottle.By with the predetermined stirring time of solution bottle rotation, realized the even mixing of cell and solution.

Therefore [162] because piston 20 moves, discharge solution under the condition of the solution of solution bottle of the present invention in the solution bottle and extraneous air isolation, thereby, extraneous air can be fed to the inside of solution bottle.Therefore, rest solution can not go bad because of air in the solution bottle, and can use afterwards.

[163] when opening the lid 40 of solution bottle, piston 20 is risen to low height, so that reduce the pressure in the shell 1, and the solution of shell 1 can not poured out by nethike embrane 32 because of the absorption effect of pressure differential generation.Thereby, can farthest reduce the loss of solution, and prevent the contaminated aqueous solution that filtrator 50 is toppled over.

[164] because solution bottle of the present invention is preserved the solution that mixes under the condition of the bar portion 27 of piston 20 and the upper end snap-in in the guiding slit 8 of shell 1, so with the inner pumping of solution bottle, thereby prevent solution corruption in the solution bottle.

When [165] solution bottle of the present invention being inserted mixed solution form unit 100, rotation solution bottle is so that stirring projection by the solution bottle and impeller and cell is mixed equably with solution.

During [166] from solution that solution bottle discharging mixes, piston 20 freely reduces, thereby can discharge the solution of mixing from the solution bottle of sealing state.

[167] because the lid with the lock solution bottle is opened in the unit of uncapping, therefore shortened the processing time.

[168] owing to be formed at solution directional nozzle in the filtrator coupling part and be positioned at and draw below the hole, so, can prevent from that solution from flowing to draw the hole although because of the pressure in the solution bottle reduces in the solution inspiration solution bottle.

[169], can prevent that therefore microslide from being made dirty by user's hand because the microslide that the user does not participate in using the microslide operating unit that cell is transferred to microslide and will be had a cell from the collection membrane of filtrator is put into the process of alcohol.

[170] because piston connects the snap-in of releasing unit release plunger and solution bottle, therefore can reuse the solution bottle apace.

[171] tumor screening system of the present invention is reused the remaining mixed solution in the solution bottle, and does not use new solution bottle, thereby reduces the refuse amount that produces.

[172] because all operations state of tumor screening system of the present invention all is shown on the LCD panel, therefore can control tumor screening system easily.

[173] though the present invention discloses preferred embodiment for illustrative purposes, it will be understood by those skilled in the art that under the situation that does not break away from the disclosed the scope and spirit of the present invention of appended claims, can carry out various modifications, replenish and substitute.
