Embodiment
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
As shown in Figure 1, embodiments provide a kind of manual absorption type for biological tissue's detection and assist vessel, the second vessel body 20 comprise the first vessel body 10, removably connecting with described first vessel body 10 and the vacuum cavitations bar 30 being installed on described second vessel body 20, described first vessel body 10 comprises elastic film 12 and the loading base plate 13 parallel with described elastic film 12, the vessel body wall of described elastic film 12, loading base plate 13 and the first vessel body 10 forms an adsorption chamber, and wherein said loading base plate 13 is provided with negative pressure hole 131.In the present embodiment, described first vessel body 10 is threaded with described second vessel body 20, and is provided with packing washer 14 between the two, to ensure the sealing that both connect.
Owing to there is cross-infection between different biological tissue, so described first vessel body 10 is specially disposable interchangeable medical vessels in embodiments of the present invention, the specification of the first vessel body 10 can be chosen according to biological tissue's size; Stop biological tissue and related liquid to enter in the second vessel body by elastic film 12 simultaneously.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.
Wherein, described vacuum cavitations bar 30 comprises coupling shaft 31, the piston slider 32 be connected with described coupling shaft 31, the seal gasket 33 being closely set in described piston slider 32 1 end face, coupling shaft limited block 34, frustum ball-and-socket 35, volute spring 36 and cam handle 37; Described second vessel body 20 is separated into negative pressure chamber 21 and pulpit 22 by described piston slider 32 and described seal gasket 33 jointly; Described volute spring 36 and frustum ball-and-socket 35 are sheathed on described coupling shaft 31 successively, and the large end face of wherein said volute spring 36 is relative with the large end face of described frustum ball-and-socket 35; Described coupling shaft 31 one end is connected with the internal thread frustum platform 38 being built in described piston slider 32, and its other end is connected with described cam handle 37 axle.
In addition, in order to prevent coupling shaft 31 from coming off from internal thread frustum 38, the part coupling shaft 31 being positioned at described pulpit 22 is in the present embodiment provided with coupling shaft limited block 34.Because internal thread frustum 38 is fixed on piston slider 32, when be rotatably connected axle 31 time, piston slider 32 can be drawn; But in screwing operations, piston slider 32 and seal gasket 33 move right (taking Fig. 1 as reference map), thus increase absorption affinity, now there is not the risk that comes off in coupling shaft 31.When cam handle 37 drives coupling shaft 31 to anticlockwise (releasing orientation reduces negative pressure pressure), coupling shaft 31 may come off because rotating from internal thread frustum 38, and now limited block 34 plays and avoids the risk that comes off.
In order to ensure the first vessel body and the second vessel body detachable, in the present embodiment, the side external surface of described first vessel body 10 is provided with the first threaded portion 11, the top of the negative pressure chamber 21 of described second vessel body 20 is provided with an opening, and described opening inwall is provided with the second threaded portion 211 be meshed with described first screw thread 11.In addition, as shown in Figure 2, described negative pressure hole 131 be provided with multiple and be close to described loading base plate 13 center distribution so that firmly biological tissue specimens can be adsorbed.
Described negative pressure chamber 21 inwall of the second vessel body 20 and the sidewall of described seal gasket 33 are respectively equipped with the spring anchor block 23 be oppositely arranged each other, and are provided with the retracing spring 24 for resetting piston slide block 32 between described spring anchor block 23.The distance of the wide distance core wheel of the wheel limit due to cam handle 37 not etc., when cam handle 37 locks tension state, does not make piston slider 32 guide fast under the traction of retracing spring 24 and is returned to normal condition.
As shown in Figure 4, when moving cam handle 37 and that is to say that the sidewall of pulpit 22 and cam handle 37 are in plumbness (being considered as negative pressure adjustment state), frustum ball-and-socket 35 unclamps volute spring 36, coupling shaft 31 is driven to rotate by rotating cam handle 37, form the traction of coupling shaft 31 pairs of pistons 32, thus control the vacuum magnitude of negative pressure chamber.
As shown in Figure 5, after adjustment, when compressing cam handle 37 namely the sidewall of pulpit 22 and cam handle 37 be in parastate (being considered as locking state), now cam handle 37 is locked, negative pressure chamber 21 forms constant negative pressure region, traction elastic film 12 is bent downwardly, and the negative pressure hole 131 be distributed on loading base plate 13 firmly adsorbs biological tissue specimens.
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.
