Abstract
The utility model discloses a kind of medical negative pressure drainage devices, including feed bin and piston, piston slides fixation in feed bin, the inner wall sealing of the periphery wall and feed bin of piston is slidably matched, feed bin is divided into two closed cavitys by piston, check valve is offered on piston, is provided with inlet and liquid outlet on feed bin.The utility model is by being divided into two cavitys for feed bin in piston, when pushing piston drain, the liquid of inlet is also inhaled into feed bin therewith, during may be implemented piston return by the check valve on piston again, liquid circulates in two cavitys, after the completion of piston return, piston drain is pushed again, completes a whole set of process.The utility model structure is simple, and drain and feed liquor can carry out simultaneously, save the amount of labour of half compared with prior art, improve work efficiency.
Description
Technical field
The utility model relates to medical nursing instrument fields, and in particular to a kind of medical negative pressure drainage device.
Background technique
In medical nursing, depression drainage device is generally used for drawing patient body fluid or inputs medical fluid, liquid food etc. for patient.
Existing negative pressure drainage device, generally comprises inlet, liquid outlet and cavity, and inlet and liquid outlet are provided with list
It to valve, now draws liquid into cavity, is discharged from cavity using liquid outlet, feed liquor and out liquid cannot carry out simultaneously, only
Drain and feed liquor movement can be discontinuously executed, efficiency is lower.
Utility model content
The utility model aim be to provide for it is a kind of can feed liquor and drain simultaneously negative pressure drainage device.
To achieve the goals above, the utility model use following technical scheme, a kind of medical negative pressure drainage device, including
Feed bin and piston, piston slide fixation in feed bin, and the inner wall sealing of the periphery wall and feed bin of piston is slidably matched, and piston will expect
Storehouse is divided into two closed cavitys, and the check valve of two cavitys of connection is offered on piston, be provided on feed bin inlet and
Liquid outlet, inlet and liquid outlet are respectively connected to two cavitys, and restricted liquid, which is arranged, in inlet can only flow into feed bin
Check valve, restricted liquid, which is arranged, in liquid outlet can only flow out the check valve of feed bin, and check valve on piston control liquid can only be from
Inlet flows to liquid outlet.
Further, liquid outlet is communicated with picking-up container by drain pipe.
Further, piston rigid connection is extended outside discharging bin by piston rod, piston rod, the joining place of piston rod and feed bin
It is slidably matched using sealing.
Further, the free end of piston rod is provided with the handle for facilitating holding to have an effect.
Further, feed bin is into hollow column, and inlet and liquid outlet are separately positioned on the both ends of feed bin.
The utility model is by being divided into two cavitys for feed bin in piston, when pushing piston drain, the liquid of inlet
Body is also inhaled into feed bin therewith, then during piston return may be implemented by the check valve on piston, liquid is in two chambers
It circulates in vivo, after the completion of piston return, pushes piston drain again, complete a whole set of process.The utility model structure is simple, and
Drain and feed liquor can carry out simultaneously, save the amount of labour of half compared with prior art, improve work efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The technical solution of the utility model is further elaborated below with reference to specific embodiment.
A kind of embodiment of medical negative pressure drainage device as shown in Figure 1, including feed bin 1 and piston 2, piston 2 it is outer
The inner wall sealing of peripheral wall and feed bin 1 is slidably matched, and the rigid connection of piston 2 is extended outside discharging bin 1 by piston rod 6, piston rod 6, living
Stopper rod 6 and the joining place of feed bin 1 are slidably matched using sealing；Feed bin 1 is divided into two closed cavitys by piston 2, on piston 2
The check valve 5 of two cavitys of connection is offered, inlet 4 and liquid outlet 3 are provided on feed bin 1, inlet 4 and liquid outlet 3 are each
From two cavitys are respectively communicated with, restricted liquid, which is arranged, in inlet 4 can only flow into the check valve of feed bin, and liquid outlet 3 is arranged limited
Liquid processed can only flow out the check valve of feed bin, and the check valve 5 on piston 2, which controls liquid, to flow to liquid outlet from inlet.
The body fluid of patient splashes in order to prevent, and then spreads the disease, and liquid outlet 3 is communicated with picking-up container 8 by drain pipe.
In order to facilitate holding and having an effect, the free end of piston rod 6 is provided with handle 7.
Feed bin 1 is into hollow column, and inlet 4 and liquid outlet 3 are separately positioned on the both ends of feed bin 1, past in piston 2
During multiple movement, inlet 4 and liquid outlet will not go here and there storehouse.
The principle of the present embodiment is as follows, and for piston 2 during force feed to the left, the cavity on right side is in negative pressure, liquid from
Inlet 4 enters；Left side cavity is in high pressure, and the intracorporal liquid of left side cavity is discharged into picking-up container 8 by liquid outlet 3；Piston 2 from
During left-to-right return, check valve 5 is opened, and the intracorporal liquid of right-side cavity flows into left side cavity body, inlet 4 during this
It is flowed with the equal no liquid of liquid outlet 3, piston 2, which moves to the rightmost side, can then start next round force feed.
Unmentioned technology is the prior art in the utility model.
The utility model embodiment is the preferred embodiment of technical solutions of the utility model, but is not to the utility model
Embodiment further limits, it is any deterioration or equivalents should belong to the protection scope of the utility model claims with
It is interior.
