Abstract
The utility model discloses a kind of depression drainage devices of integrated form, belong to technical field of medical equipment, including telescopic shell, spring, damper, the telescopic shell bottom is equipped with fixed plate, top is equipped with unidirectional gas valve；It is equipped with liquid trap inside the telescopic shell, the inner space connection of opening with telescopic shell is equipped at the top of the liquid trap, conduit fixing port is additionally provided at the top of the liquid trap, conduit is connected on conduit fixing port, the conduit is stretched out from fixed plate；The both ends of the spring and damper are connect with telescopic shell top, fixed plate respectively, and the damper is nonlinear displacement associated damper.The utility model realizes that the negative pressure in entire telescopic shell is constant using spring and damper, with simple, the at low cost advantage of structure.
Description
Technical field
The utility model relates to technical field of medical equipment, in particular to a kind of depression drainage device of integrated form.
Background technique
In the course of disease treatment, negative pressure drainage is generally required.Presently, there are the problem of: 1, negative pressure is non-constant, needs to protect
Reason personnel's timing goes to squeeze drainage device generation negative pressure, had not only increased nursing staff's workload but also constant negative pressure continuous drainage is not achieved
Purpose；2, flow diverter metering inaccuracy, for part drainage-fluid less than 100ml, nursing staff just uses syringe to release again
Measurement, not only the risk of nosocomial infection occurred for waste of manpower but also increase.The utility model solve negative pressure it is constant, accurate measurement two
Problem.
Utility model content
The purpose of this utility model is to provide a kind of depression drainage devices of integrated form, are realized using spring and damper whole
Negative pressure in a telescopic shell is constant.
To realize the utility model aim, the technical solution of use are as follows: a kind of depression drainage device of integrated form, feature exist
In, including telescopic shell, spring, damper, the telescopic shell bottom is equipped with fixed plate, top is equipped with unidirectional gas valve；
It is equipped with liquid trap inside the telescopic shell, the inner space connection of opening with telescopic shell, institute are equipped at the top of the liquid trap
It states and is additionally provided with conduit fixing port at the top of liquid trap, conduit is connected on conduit fixing port, the conduit is stretched out from fixed plate；Institute
The both ends for stating spring and damper are connect with telescopic shell top, fixed plate respectively, and the damper is that nonlinear displacement is related
Damper.
Further, the liquid trap divides inner cavity and exocoel, the top of the inner cavity and exocoel connection, on inner cavity and exocoel
It is equipped with scale.
Further, the liquid trap bottom is fixed on the connecting plate that one piece is detachably connected with fixed plate, connecting plate
Sealing is formed between fixed plate.
The utility model has the beneficial effects that constant negative pressure is formed inside telescopic shell using spring and damper,
By catheter drainage, be stored in internal liquid trap, liquid trap can by being taken out in the fixed plate of bottom, be convenient for changing or
Person's sampling.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the depression drainage device of integrated form；
Fig. 2 is the sectional structure chart of the depression drainage device of integrated form.
Specific embodiment
The utility model is further described in detail below through specific implementation examples and in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 shows the depression drainage device of integrated form provided by the utility model, including telescopic shell 2, spring 6,
Damper 5,2 bottom of telescopic shell is equipped with fixed plate 3, top is equipped with unidirectional gas valve 4；Liquid collecting is equipped with inside telescopic shell 2
Device 7 is equipped with the inner space connection of opening 8 with telescopic shell 2 at the top of liquid trap 7, is additionally provided with conduit at the top of liquid trap 7 and fixes
Mouthful, it is connected with conduit 1 on conduit fixing port, conduit 1 is stretched out from fixed plate 3；The both ends of spring 6 and damper 5 respectively with stretch
2 top of contracting shell, fixed plate 3 connect, and damper 5 is nonlinear displacement associated damper.
Further, liquid trap 7 divides inner cavity 11 and exocoel 12, and the top of inner cavity 11 and exocoel 12 are interior by 9 connection of aperture
Scale is equipped on chamber 11 and exocoel 12.
Further, 7 bottom of liquid trap is fixed on one piece of connecting plate being detachably connected with fixed plate 10, connecting plate 10
Sealing is formed between fixed plate 3.
In the process of work, we place flow diverter on the table, and conduit is stretched to the portion that sufferer needs to drain
Position manually compresses at the top of telescopic shell, and internal gas is discharged by the unidirectional gas valve 4 at top, after release, in spring 6
Restoring force under the action of, keep telescopic shell 2 in there are a negative pressure, play the role of drainage；Damper 5 is one non-thread
The displacement associated damper of property, different according to the difference of stroke because the elastic force of spring is non-constant, damper is properly balanced
This variation, so that the negative pressure in telescopic shell generally remains constant；Liquid enters the inner cavity 11 of liquid trap 7 by conduit 1, when
It after inner cavity 11 has been expired, is overflowed automatically by aperture 9, reaches exocoel.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, there can be various modifications and variations in the spirit and principles of the utility model, these are equivalent
Variation or replacement etc., are included in the protection scope of the present invention.
