Detailed description of the invention
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment one:
As depicted in figs. 1 and 2, embodiments provide a kind of automatic absorbing type for biological tissue's detection and assist vessel, the second vessel body 20 comprising the first vessel body 10, removably connect with described first vessel body 10, wherein said second vessel body 20 is divided into negative pressure chamber 21 and control room 22 by seal gasket 24 and piston block 22, and the upper wall of described negative pressure chamber 21 is connected with piston block 22 by Return spring 211; Described piston block 23 1 surface is pasted with described seal gasket 24 and is fixedly connected with, and its another surface is fixed with metal derby 25; Described control room 22 is provided with the electromagnetic traction control device 26 with described metal derby 25 magnetic absorption.
In the specific embodiment of the invention, described first vessel body 10 is threaded with described second vessel body 20.In order to ensure that confined space forms negative pressure, between described first vessel body 10 and described second vessel body 20, be provided with sealing ring 13.Wherein said metal derby 25 is made primarily of metallicl magnetic material or ferrite, and described metal derby 25 is the iron block be made by ferrite in embodiments of the present invention.
In addition, in order to avoid cross-infection, the first vessel body described in the embodiment of the present invention is disposable replaceable medical vessels.And the specification of the first vessel body 10 is chosen according to biological tissue's size, the number that the specification of wherein said first vessel body 10 is provided with negative pressure hole 131 according to loading base plate 13 divides, and such as the specification of described first vessel body 10 is 1 × 1,1 × 2,1 × 3,1 × 4 ... 1 × n.
The bottom 11 of described first vessel body 10 is provided with negative pressure hole 111, and establishes spaced elastic film 12 below being positioned at bottom described first vessel body 11.In embodiments of the present invention, described negative pressure hole 111 is provided with five, and to be distributed in bottom described first vessel body 11, biological tissue larger acquired by being mainly convenient to.
Described electromagnetic traction control device 26 comprises iron core 261, conductive winding 262, power switch 263, adjustable potentiometer 264 and power supply 265 around described iron core 261, wherein said conductive winding 262 one end is connected with the electrode tip of adjustable potentiometer 264 with described power supply 265 by power switch 263, and its other end is connected with another electrode tip of described power supply 265.When power switch 263 closes, the internal control circuit conducting of described electromagnetic traction control device 26 also produces magnetic field, make to produce magnetic field force between iron core and metal derby, thus make iron core and metal derby mutually draw generation pulling force, and drive piston block to move downward to make negative pressure chamber to form negative pressure, allow being covered in the biological tissue on negative pressure hole and being adsorbed under the effect of negative pressure.If when user needs increase or reduce absorption affinity, can change electric current by adjustable potentiometer 264, thus change magnetic field adjusts adsorption strength.
In order to make to avoid in measuring process Return spring 211 to pull back excessive and negative effect that is that cause, the sidewall bilateral symmetry of described second vessel body 20 is provided with limited block 212 in embodiments of the present invention, and described limited block 212 is positioned at the top of described piston block 22.
As shown in Figure 3, when power switch 263 closes, electric current is by conductive winding 262, iron core 261 is made to produce magnetic force, cause iron block 25 under magnetic-adsorption effect, drive piston block 23 to move downward, make negative pressure chamber 21 produce negative pressure and elastic film 12 to lower recess (as shown in front in Fig. 3), finally allow biological tissue be adsorbed on the negative pressure hole 111 of bottom the first vessel body 11.In addition, user can change the electric current in conductive winding 262 in real time by adjustment adjustable potentiometer 264, thus the magnetic force realizing iron core 261 generation can vary in size, and also reaches the flexible modulation to biological tissue's absorption affinity.Such as: the fixing absorption affinity needed for fritter biological tissue is little, the first vessel body of the few specification of negative pressure hole number can be selected; Fixing absorption affinity needed for bulk biological tissue is large, can select the first vessel body of the few specification of negative pressure hole number.
Embodiment two:
As shown in Fig. 2,3 and 4, another embodiment of the present invention embodiments provides a kind of automatic absorbing type for biological tissue's detection and assists vessel, be that described negative pressure hole 111 is provided with three with above-described embodiment one main distinction, other structures are identical with above-described embodiment one, do not repeat them here.In the present embodiment, except may be used for comparatively except mcroorganism tissue (such as above-described embodiment one) also can be used for comparatively atom tissue.
In addition, the size of sometimes biological tissue's acquisition is smaller, and at this moment negative pressure hole 111 of the present invention can also choose the first vessel body being distributed as a negative pressure hole, can also select the negative pressure hole of which kind of size according to the size of biological tissue.Therefore, negative pressure hole 111 shape on described first vessel body 10, size and number all can not wait, again because described first vessel body 10 can be disposable interchangeable, so described negative pressure hole 111 can be provided with one, more than two or two, and to be distributed in bottom described first vessel body on 11, mainly decide according to biological tissue's size to be detected.
Foregoing is only preferred embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
