Specific embodiment
As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.
As shown in Figure 1, the embodiment of the invention provides a kind of manual absorption types for biological tissue's detection to assist vessel,
Including the first vessel body 10, the second vessel body 20 being detachably connected with first vessel body 10 and it is installed on second device
The vacuum cavitations bar 30 of ware body 20, first vessel body 10 include elastic film 12 and the load parallel with the elastic film 12
The vessel body wall of object bottom plate 13, the elastic film 12, loading bottom plate 13 and the first vessel body 10 forms an adsorption chamber, wherein
The loading bottom plate 13 is equipped with negative pressure hole 131.In the present embodiment, first vessel body 10 and 20 spiral shell of the second vessel body
Line connection, and it is equipped with seal washer 14 between the two, to guarantee the leakproofness of the two connection.
Since there are cross-infections between different biological tissues, so first vessel body 10 in embodiments of the present invention
Specially disposable interchangeable medical vessels, can choose the specification of the first vessel body 10 according to biological tissue's size；Together
When prevent biological tissue and related liquid from entering in the second vessel body by elastic film 12.Wherein first vessel body 10
Specification is divided according to the number that loading bottom plate 13 is equipped with negative pressure hole 131, for example, the specification of first vessel body 10 be 1 × 1,
1×2、1×3、1×4……1×n。
Wherein, the vacuum cavitations bar 30 include connecting shaft 31, with the connecting shaft 31 connect piston slider 32, be close to
It is set to seal gasket 33, connecting shaft limited block 34, frustum ball-and-socket 35,36 and of volute spring of 32 1 end face of piston slider
Cam handle 37；Second vessel body 20 is separated into negative pressure chamber 21 jointly by the piston slider 32 and the seal gasket 33
With control room 22；Described 31 one end of connecting shaft is connect with the internal screw thread frustum 38 for being built in the piston slider 32, the other end
With 37 axis connection of cam handle；The volute spring 36 and frustum ball-and-socket 35 are successively sheathed in the connecting shaft 31,
Described in volute spring 36 large end face it is opposite with the large end face of the frustum ball-and-socket 35, the volute spring 36, frustum ball-and-socket
35 and cam handle 37 be respectively positioned on that control room 22 is outer and frustum ball-and-socket 35 is between volute spring 36 and cam handle 37.
In addition, connecting shaft 31 is popped up from control room 22 in order to prevent, it is located in the control room 22 in the present embodiment
Part connecting shaft 31 is equipped with connecting shaft limited block 34.Since internal screw thread frustum 38 is fixed on piston slider 32, when rotation connects
When axis 31, piston slider 32 can be drawn；But in screwing operations, piston slider 32 and seal gasket 33 are moved right (with Fig. 1
On the basis of scheme), to increase adsorption capacity, there is no pop-up risks for connecting shaft 31 at this time.When cam handle 37 drives connecting shaft 31
When rotating to the left (releasing orientation reduces negative pressure pressure), connecting shaft 31 may fall off from internal screw thread frustum 38 because rotating out of,
Limited block 34 plays the risk for avoiding popping up from control room 22 at this time.
In order to guarantee that the first vessel body and the second vessel body are detachable, in the present embodiment, first vessel body 10
Side external surface is provided with the first threaded portion 11, and the top of the negative pressure chamber 21 of second vessel body 20 is equipped with an opening, described
Opening inner wall is equipped with the second threaded portion 211 being meshed with first screw thread 11.In addition, as shown in Fig. 2, the negative pressure hole
131 are equipped with multiple and punish cloth close to the center of the loading bottom plate 13, in order to can firmly adsorb biological tissue specimens.
21 inner wall of negative pressure chamber of second vessel body 20 and the side wall of the seal gasket 33 are respectively equipped with opposite each other
The spring anchor block 23 of setting, and the return spring for resetting piston sliding block 32 is installed between the spring anchor block 23
24.Since distance of the wheel side exterior feature apart from core wheel of cam handle 37 differs, when cam handle 37 is in releasing orientation, piston is sliding
Quickly guidance is returned to normal condition to block 32 under the traction of return spring 24.
As shown in figure 4, that is to say that the side wall of control room 22 and cam handle 37 are in vertical configuration when moving cam handle 37
(it is considered as negative pressure adjustment state) when state, frustum ball-and-socket 35 unclamps volute spring 36, can drive and connect by rotation cam handle 37
Axis 31 rotates, and traction of the connecting shaft 31 to piston 32 is formed, to control the vacuum magnitude of negative pressure chamber.
As shown in figure 5, after adjusting, the namely side wall of control room 22 of pressing cam handle 37 and cam handle 37
(it is considered as locking state) when in parastate, cam handle 37 is locked at this time, and negative pressure chamber 21 forms constant negative pressure region, leads
Draw elastic film 12 to be bent downwardly, the negative pressure hole 131 being distributed on loading bottom plate 13 firmly adsorbs biological tissue specimens.
Above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
