Detailed description of the invention
Below with reference to drawings and the specific embodiments describe in detail the technical solution of the utility model so as clearer, understand invention essence of the present utility model intuitively.
Fig. 1 is the overall structure schematic diagram of the structure improved vacuum extractor of this utility model; Fig. 2 is the overall structure schematic diagram of the sacculus of imbibition described in Fig. 1;
Described in composition graphs 1 and Fig. 2;
The structure improved vacuum extractor of one provided by the utility model, is mainly used in the absorption places such as the wound of patient being carried out to remained blood.
Specifically, this utility model comprises pipette 10 and imbibition sacculus 20, the end of described pipette 10 is connected with the liquid feeding end of described imbibition sacculus 20, and the end of described pipette 10 is provided with a non-return valve 30, improvement of the present utility model is: also comprise a flash vessel 40 stored in order to the liquid drawn described imbibition sacculus 20, described imbibition sacculus 20 also comprises a liquid outlet, the liquid feeding end of described flash vessel 40 is connected by the liquid outlet of a drainage tube 50 with described imbibition sacculus 20, and the liquid outlet of described imbibition sacculus 20 be provided with one can the control valve 60 of folding.
Based on described above, be understandable that, operational approach of the present utility model is:
When drawing the liquid of region of interest of patient, closing described control valve 60, by extruding described imbibition sacculus 20, discharging its inner air, by suction function, the liquid of the region of interest of patient can be drawn to described imbibition sacculus 20 by described pipette 10.
When needing to shift the liquid drawn, directly open described control valve 60, because the imbibition end of described pipette 10 communicates with air, by the effect of atm difference inside and outside described imbibition sacculus 20, the liquid in described imbibition sacculus 20 very naturally can be made to be drained to described flash vessel 40 by described drainage tube 50 automatically and to be stored.
When the transfer of relevant body fluid is complete, then close described control valve 60, the absorption of the liquid of next round can be carried out, so move in circles, operating process can be made uninterrupted, avoid extruding trouble and negative effect that described imbibition sacculus 20 brings.
So, because of the structure improved vacuum extractor of one provided by the utility model, because being provided with the flash vessel 40 be connected with described imbibition sacculus 20, on the one hand, after filling the liquid of absorption in described imbibition sacculus 20, relevant imbibition sacculus 20 need not be dismantled filled liquid is outwelled or shifted, but directly open described control valve 60, directly the liquid filled in described imbibition sacculus 20 is drained to described flash vessel 40 by the vacuum force of air to store, in the process of drain, also relevant imbibition sacculus 20 need not be extruded, make easy to use, time saving and energy saving, and make when the region of interest imbitition to patient, continuous operation can be accomplished.
On the other hand, because relevant imbibition sacculus 20 need not be dismantled, also relevant imbibition sacculus 20 need not be extruded, what make to avoid the antibacterial in air etc. to pass through relevant imbibition sacculus 20 because of extruding is drawn in relevant imbibition sacculus 20, cause the pollution of relevant imbibition sacculus 20 itself, and then cause and infect with reporting to the leadship after accomplishing a task of patient and infect with reporting to the leadship after accomplishing a task of nurse, thus, this utility model is practical, and result of use is good.
Further, in the specific implementation, also comprise one and press from both sides in order to the Non-follow control of pipette described in Non-follow control 10 opened/closed, described Non-follow control sandwiched is placed in outside described pipette 10 this utility model.
So, when not using, tightening described Non-follow control folder 70, described pipette 10 can be closed.
Further, in this utility model embodiment, the capacity of described flash vessel 40 is greater than the capacity of described imbibition sacculus 20.
And in a preferred embodiment, the capacity of described flash vessel 40 is more than the twice of the capacity of described imbibition sacculus 20.
And, in this utility model embodiment, the liquid feeding end of described flash vessel 40 is connected with described drainage tube 50 is detachable, the liquid feeding end of described imbibition sacculus 20 is connected with the end of described pipette 10 is detachable, and the liquid feeding end of described imbibition sacculus 20 is provided with one in order to connect the suction nozzle 201 of described pipette 10, the cross section of described suction nozzle 201 is trapezoidal.
So, because described pipette 10, imbibition sacculus 20, drainage tube 50 and flash vessel 40 are detachable respectively, make to be convenient to cleanse and disinfect etc., and because of the cross section of described suction nozzle 201 be trapezoidal, described imbibition sacculus 20 can be matched with the pipette 10 of different-diameter assemble, make this utility model practical.
Further, it should be noted that, in the present embodiment, described in described imbibition sacculus 20, the capacity of imbibition sacculus 20 can adopt 50ml specification, 100ml specification and 200ml specification etc., and certainly, it also can be other capacity specifications.
You need to add is that, for making described pipette 10 better with the connectivity of described imbibition sacculus 20, the mode that described pipette 10 can adopt screw thread to spin is connected with described suction nozzle, so, namely make connection reliability good, good stability, good leak tightness, further, in this utility model embodiment, described pipette 10 and drainage tube 50 are respectively hose materials, described imbibition sacculus 20 is elastic silica gel material, other embodiments etc., at this, do not illustrate one by one.
In sum, the structure improved vacuum extractor of one provided by the utility model, be provided with the flash vessel 40 be connected with described imbibition sacculus 20, on the one hand, after filling the liquid of absorption in described imbibition sacculus 20, relevant imbibition sacculus 20 need not be dismantled filled liquid is outwelled or shifted, but directly open described control valve 60, directly the liquid filled in described imbibition sacculus 20 is drained to described flash vessel 40 by the vacuum force of air to store, in the process of drain, also relevant imbibition sacculus 20 need not be extruded, make easy to use, time saving and energy saving, and make when the region of interest imbitition to patient, continuous operation can be accomplished.
On the other hand, because relevant imbibition sacculus 20 need not be dismantled, also relevant imbibition sacculus 20 need not be extruded, what make to avoid the antibacterial in air etc. to pass through relevant imbibition sacculus 20 because of extruding is drawn in relevant imbibition sacculus 20, cause the pollution of relevant imbibition sacculus 20 itself, and then cause and infect with reporting to the leadship after accomplishing a task of patient and infect with reporting to the leadship after accomplishing a task of nurse, thus, this utility model is practical, and result of use is good.
Accordingly, this utility model is applicable to the absorption skin wound place of patient being carried out to remained blood or congestion, or the sputum of patient is drawn, certainly, it is also applicable to the absorption of other related liquid, and, this utility model, in the improvement of structure and in the improvement of technology, does not all need to increase too many cost, makes this utility model must have good market popularization value, this utility model can very welcome, can effectively be popularized.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize this utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
