Abstract
A negative pressure flow draining device that prevents reverse attraction relates to the art of medical devices. The utility model is structurally characterized in that a floater cup (1) is sleeved at the lower end of the short attraction tube of a flow draining bottle, and is fixed firmly with the short attraction tube. The axes of the floater cup and the short attraction tube are in superposition. The floater cup (1) is internally provided with a floater (4) on the top of which a pipe closer (3) is provided. The floater (4) and the pipe closer (3) can move along the axes in the floater cup (1). The wall of the floater cup (1) is also arranged with a placket (2) for the flowing of liquid. The utility model has the advantages of simple structure, low cost, strong practicability and so on.
Description
Technical field
This utility model belongs to the medical appliance field, specifically a kind of negative pressure drainage anti-suck device.
Background technology
Need constantly to remove hematocele, the hydrops of operating field in the operation process,, be convenient to operation safety and carry out smoothly to keep the clear of operating field.Traditional negative pressure drainage device lacks the anti-suck function, what of drainage flow the nurse must constantly observe, increase workload, the patient can not feel at ease to perform the operation, and drainage bottle is changed untimely, drain liquid easily is inhaled into the central suction pipeline to be caused polluting, and then causes the central suction pipeline obstruction for a long time, influences the vacuum suction effect.
Summary of the invention
In order to overcome the deficiency of conventional art, this practicality provides a kind of anti-suck negative pressure drainage device, utilizes the sink-float restriction of float negative pressure is gravitational to open and close, and reaches the practical requirement of anti-suck.
This utility model solves technical scheme that its technical problem adopts: a kind of anti-suck negative pressure drainage device, be provided with drainage bottle, two suction pipes that are equipped with on its seal cover that one is long and the other is short, it is characterized in that being enclosed within the lower end of short suction pipe with float cup (1), and with this suction pipe fix tightly, make the two dead in line, float (4) is housed in the float cup (1), pipe plug (3) is equipped with in the top of float (4), float (4) and pipe plug (3) can be along axial-movements in float cup (1), and also being provided with on the wall of float cup (1) can mobile for liquid opening (2).
This utility model is simple in structure, and is practical, and cost is low, helps improving nursing quality, alleviates medical personnel's work load.
Description of drawings
Below in conjunction with accompanying drawing, this utility model is described in detail by embodiment.
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Shown in Figure 1, be the drainage bottle that generally adopts at present, two suction pipes that are equipped with on its seal cover that one is long and the other is short, select a rubber closure that matches with float cup (1) bore, heart perforate therein, make diameter and short suction pipe external diameter tight fit, rubber closure is enclosed within on the float cup (1), and the rubber closure tapping is enclosed within on the short suction pipe, fixation, the axis of cup is overlapped with this tubular axis line, float (4) is housed in the float cup (1), pipe plug (3) is equipped with in the top of float (4), float (4) and pipe plug (3) can be along axial-movements in float cup (1), and also being provided with on the wall of float cup (1) can mobile for liquid opening (2).
The suction pipe that will be with float cup (1) during use connects central suction, another suction pipe is connected on the operating-table, open the vacuum suction switch, regulate pressure and can use, the interior gas of drainage bottle this moment is sucked away by the opening on float cup (1) wall and forms negative pressure, attract the hematocele hydrops, the interior liquid level of drainage bottle is raise gradually, and float (4) raises with the rising of liquid level, when liquid level is elevated to desired location, float (4) drives pipe plug (3) mouth of pipe is blocked, and prevents suck-back.
Claims (1)
- A kind of anti-suck negative pressure drainage device, be provided with drainage bottle, two suction pipes that are equipped with on its seal cover that one is long and the other is short, it is characterized in that being enclosed within the lower end of short suction pipe, and, make the two dead in line with this suction pipe fix tightly with float cup (1), float (4) is housed in the float cup (1), pipe plug (3) is equipped with in the top of float (4), and float (4) and pipe plug (3) can be along axial-movements in float cup (1), and also being provided with on the wall of float cup (1) can mobile for liquid opening (2).
