Detailed description of the invention
As shown in figures 1 to 6, specimen needle cleaning device described in the utility model, comprise the cylindrical cleaning post 1 that resin material is made and the resin end cap 6 be threaded connection in cleaning post 1 bottom, axially extending bore is offered at end cap 6 center, and the first draining connector 7 that this through hole and silicon rubber are made is flexibly connected by screw thread.Cleaning post 1 inside offers five chambers vertically, is respectively: the first cleaning chambers 2, two lays respectively at the first spill cavity 3 of the first cleaning chambers 2 both sides, the second cleaning chambers 4 being positioned at cleaning post 1 center and the second spill cavity 5(of being positioned at the second cleaning chambers 4 side is specifically shown in Fig. 2).The setting of above-mentioned form, on the basis making full use of cylindrical cleaning post 1 space, can increase the volume of each spill cavity as wide as possible, ensure that specimen needle can obtain abundant cleaning, not produce and spatter liquid, and discharge opeing is unobstructed.Except the second cleaning chambers 4, all the other cavitys all extend to cleaning post 1 lower surface from cleaning post 1 upper surface always, and the small gap arranged between cleaning post 1 lower surface and end cap 6 upper surface, form the runner between above-mentioned cavity and the first draining connector 7, the liquid in its cavity discharges cleaning post 1 by the first draining connector 7.In order to prevent the generation of the phenomenon of leakage, sealing ring 13 can be set between cleaning post 1 and end cap 6.Cleaning post sidewall is threaded connection the first fluid injection joint 8, second fluid injection joint 9 and the second draining connector 10 that silicon rubber is made, wherein, be connected with the first cleaning chambers 2, second cleaning chambers 4 top respectively by cleaning post 1 internal pipeline with the first fluid injection joint 8, second fluid injection joint 9; In specimen needle cleaning process, outer wall occurs hanging liquid phenomenon, and the second draining connector 10 is connected (specifically seeing Fig. 3-6) with the second cleaning chambers 4 bottom by cleaning post 1 internal pipeline, arranges drain line separately.The the second fluid injection joint 9 be connected with the second cleaning chambers 4 is two, is separately positioned on cleaning post 1 both sides, (specifically seeing Fig. 2) arranged in parallel.Cleaning fluid can be made to rush at specimen needle in the shape of a spiral, ensure that specimen needle outer wall circumference obtains fully cleaning.The first overflow launder 11 of tilting respectively to two the first spill cavities 3 along described first cleaning chambers 2 sidewall and the second overflow launder 12 from the second cleaning chambers 4 to the second spill cavity 5 that tilt along is respectively arranged with in the upper surface of cleaning post 1.
During use, first specimen needle is placed in the first cleaning chambers 2, constantly in cavity, alkali lye is injected from the first fluid injection joint 8, specimen needle is drawn alkali lye and is carried out inner wall washing, when alkali lye fills the first cleaning chambers 2, can be entered in the first spill cavity 3 by superposed first overflow launder 11, and constantly discharge cleaning post 1 by the first draining connector 7 bottom end cap 6.When specimen needle carries out alkali cleaning, adopting this alkali lye constantly to inject and continuous mode of discharging from the first spill cavity 3 from the first fluid injection joint 8, is clean specimen needle inwall to ensure sufficient fresh alkali lye.After carrying out alkali cleaning to specimen needle inwall, stop alkali lye injecting, and by the first draining connector 7, alkali lye remaining in first cleaning chambers 2 and the first spill cavity 3 is discharged.By external manipulation mechanism, specimen needle is entered in the second cleaning chambers 4 from the first cleaning chambers 2, then constantly in cavity, purified water is injected by the second fluid injection joint 9, specimen needle outer wall is cleaned, when purified water fills the second cleaning chambers 4, the purified water of carrying impurity can be entered in the second spill cavity 5 by superposed second overflow launder 12, and constantly discharges cleaning post 1 by the first draining connector 7 bottom end cap 6.In specimen needle cleaning process, outer wall occurs hanging liquid phenomenon, and the liquid bottom the second cleaning chambers 4 also can be discharged separately by the exterior line be connected on cleaning post 1 sidewall second draining connector 10.After having washed, stop the injection of purified water, and liquid remaining in the second cleaning chambers 4 and the second spill cavity 5 is discharged.By above alkali cleaning and water-washing process, complete the cleaning operation to specimen needle.
Alkali cleaning chamber of the present utility model and washing chamber are provided separately, and can clean respectively, improve cleaning performance to specimen needle inner and outer wall.In addition, two alkali cleaning spill cavities are set, increase overflow area, to solve when carrying out noting alkali lye to specimen needle inner chamber in the past easily bang splash cleaning chambers edge and spatter the phenomenon of liquid.Enough large alkali lye spill cavity and purified water spill cavity, be connected with the through hole of lower end cap, can ensure that discharge opeing is unobstructed, greatly alleviate the generation of spattering liquid, ensure that the cleaning performance of specimen needle simultaneously.Each fluid injection joint and draining connector all adopt dismountable thread connecting mode, make replacing convenient, improve the utilization rate of product.
