Due on the adsorption head, can be adsorbed by the adsorption head and from puerpera take out sample tissue liquid.
For example, for the ease of the sample tissue liquid is delivered to observation and sensing chamber, the sample tissue liquid can be sealed
Loaded in Reagent Tube, gynemetrics's clinic fetus-voice meter further includes conveying mechanism 40, and the conveying mechanism is adjacent to the shell
Setting, the conveying mechanism include that lateral transfer guide rail 41, longitudinally fed guide rail 42 and push component, the lateral transfer are led
Multiple conveying through slots 411 are opened up on rail, the multiple conveying through slot is arranged in parallel, the longitudinally fed guide rail and the cross
It is vertically arranged to conveying, multiple output through slots 421, the multiple output through slot phase is offered on the longitudinally fed guide rail
It is mutually arranged in parallel, the multiple output through slot is connected to the multiple conveying through slot respectively, and the push component includes first group
Moving part 412 and the second shifting part 422, first shifting part are installed on the side of the lateral transfer guide rail and for stirring institute
The Reagent Tube in multiple conveying through slots is stated, second shifting part is installed on the side of the longitudinally fed guide rail, for stirring
Reagent Tube in the output through slot.It may be implemented by the lateral transfer guide rail being arranged with the longitudinally fed guide rail described
The conveying of the zigzag path of Reagent Tube.
For example, for the ease of the connection of the lateral transfer guide rail and the longitudinally fed guide rail, the lateral transfer is led
The end of rail is formed with the first inclination section 415, and the end of the longitudinally fed guide rail is formed with the second inclination section 425, institute
The first inclination section is stated to be bonded to each other and abut with the second inclination section so that the multiple transfer passage respectively with institute
State multiple output channel vertical connections.For example, the side of stirring for stirring direction Yu second shifting part of first shifting part
To vertical.Due to the presence of the first inclination section, the different setting of length of the multiple conveying through slot.In order to disposably will
Multiple Reagent Tubes push to the end of corresponding conveying through slot, and first shifting part includes pusher cylinder 4121 and poke rod
4122, the pusher cylinder is set to the side of the lateral transfer guide rail, and the poke rod is connected in the pusher cylinder,
The poke rod includes matrix part and elastic bending part, and described matrix portion is fixed in the pusher cylinder, the elasticity bending
Portion is rotatably connected in described matrix portion, and is extended along the direction of the vertical conveying through slot, when the conveying of wherein end
When Reagent Tube in through slot is moved to end, the elastic bending part stress and opposite described matrix portion bending, and then push phase
Adjacent Reagent Tube continuously moves to corresponding end.When all Reagent Tubes are moved to the end of corresponding conveying through slot,
The pusher cylinder drives the poke rod return, and second poke rod drives the multiple Reagent Tube along the multiple output
Through slot is mobile.
And in order to shield and sustain the multiple Reagent Tube, the end of second shifting part is formed with bending and shields and sustain side, described

Property layer, the flexible layer is used to buffer collision of the side wall in the magnetic hole to Reagent Tube.For example, the magnetic guiding loop is resistance
Ring is convexly equipped on the magnetic conductance magnet ring and connects electric ring, described to connect electric ring and be embedded in the flexible layer, when the sampling part presses on
It is described to connect electric ring set on the magnetic guiding loop to connect electric ring and the magnetic guiding loop described in realization when on the multiple Reagent Tube
Electrical communication, is provided with packaging power in the sampling part, the packaging power and it is described connect electric ring and be electrically connected, by described
The electric connection of electric ring Yu the magnetic guiding loop is connect, the magnetic guiding loop can be made to generate heat, promotes the periphery fever of the soft lid of encapsulation
Soften, become sticky.For example, being provided with pressing piece in the magnetic hole, the pressing piece is telescopically arranged in the magnetic hole,
The end of the pressing piece is provided with by pressure ring.When the sampling part moves up and is detached from the kit, the pressing piece
The pressing ring is driven to push down on the sampling part abjection magnetic hole, it is described to press on the soft lid of encapsulation by pressure ring
On periphery, and then while releasing the Reagent Tube, the periphery that the soft lid of encapsulation is squeezed by pressure ring can be also utilized
Deformation, the peripheral edge thickness of the soft lid of the encapsulation is thicker at this time and has generated heat, has become sticky, and enables and encapsulates soft lid and more seal securely
The top edge of the Reagent Tube is filled, sealing performance is improved.When the Reagent Tube deviate from the magnetic hole after, it is described connect electric ring with
The magnetic guiding loop disconnects, and then realizes power down function.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Only several embodiments of the present invention are expressed for embodiment described above, and the description thereof is more specific and detailed, but
It cannot be construed as a limitation to the scope of the present invention.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to of the invention
Protection scope.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
