Abstract

The utility model discloses a medical vacuum extractor, which comprises an elastic vacuum ball. The elastic vacuum ball is used for both storing liquid and generating vacuum and is provided with a drainage tube and a liquid outlet, the drainage tube is provided with a one-way valve, the liquid outlet is provided with a block head, the vacuum ball is also provided with an exhaust tube, and the exhaust tube is also provided with a one-way valve. Compared with the vacuum ball with the identical size in the prior art, the elastic vacuum ball can achieve higher vacuum and drainage amount during extrusion each time. Moreover, the vacuum ball can be used more safely and conveniently, and the surface of the vacuum ball is provided with volume scales for marking, thereby facilitating the measurement.

Description

A kind of medical negative pressure suction device

Technical field

This utility model relates to a kind of medical negative pressure suction device, is used for external negative pressure drainage, belongs to the armarium technical field.

Background technology

Drain is medically very common processing means, and the used drainage device of drain also has different structures.But in any case, existing drainage device comprises the container (bag or bottle) of depositing liquid without exception, is connected to drainage tube and leakage fluid dram on the container respectively, and drainage tube is provided with check valve.For liquid is drawn automatically, often need in container, produce negative pressure, and the generation of negative pressure is normally realized by negative pressure ball (rubber sacculus) or electronic facility generation negative pressure.Through constantly improving, prior art has had the structure that container and negative pressure ball are united two into one to occur.

Traditional on-electric elastic ball cryptomere drainage device must be opened the plug on the leakage fluid dram earlier before use, and gas is discharged from leakage fluid dram earlier when extruding sacculus or spheroid.Because of the retraction force generation negative pressure of spheroid, ambient atmos enters in the spheroid naturally.But the approach that gas enters spheroid both can enter from drainage tube, also can enter from leakage fluid dram, thereby can reduce the negative pressure effect, also had influence on drainage flow and speed.

The utility model content

At the prior art above shortcomings, the negative pressure that the purpose of this utility model produces when providing a kind of drain is bigger, it is safer to use and medical negative pressure suction device easily.

The technical solution of the utility model is achieved in that a kind of medical negative pressure suction device, and comprising has held concurrently deposits liquid and the elasticity negative pressure ball that produces negative pressure, and negative pressure ball is provided with drainage tube and leakage fluid dram, and drainage tube is provided with check valve, and leakage fluid dram is provided with plug.On negative pressure ball, also be provided with exhaustor simultaneously, also be provided with check valve on the exhaustor.

Further, there is the containing mark sign on the negative pressure ball surface, is convenient to metering.

Compared to existing technology, the utlity model has following advantage:

1. the drainage tube end connects check valve, and when the extruding negative pressure ball, gas can not enter drainage tube, thereby safer.

2. leakage fluid dram is blocked with plug, when extruding during negative pressure ball, gas can only be discharged from exhaustor, because exhaustor is provided with check valve apparatus, so gas can only discharge to the external world in spheroid, and the gas in the external world can not enter spheroid from exhaustor.

3. after being extruded because of negative pressure ball, the retraction force that spheroid self has, thus in spheroid, produce negative pressure.When the intravital air pressure of ball was lower than the external world, extraneous liquid just can only enter spheroid from drainage tube.

4. there is the containing mark sign on the negative pressure ball surface, is convenient to metering.

Therefore, onesize negative pressure ball, this utility model negative pressure ball push the negative pressure and the drainage flow of generation at every turn, and be more much bigger than existing negative pressure spheroid, and use more convenient.

Description of drawings

Fig. 1-this utility model structural representation.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, from the figure as can be seen, this utility model medical negative pressure suction device, comprising has held concurrently deposits liquid and produces the elasticity negative pressure ball 1 of negative pressure, negative pressure ball 1 is provided with drainage tube 2 and leakage fluid dram 3, drainage tube 2 is provided with check valve 4, leakage fluid dram 3 is provided with plug 5.On negative pressure ball 1, also be provided with exhaustor 6 simultaneously, also be provided with check valve 4 on the exhaustor 6.

For the ease of metering, this utility model is provided with containing mark 7 on the negative pressure ball surface.

During use, earlier leakage fluid dram 3 usefulness plugs 5 are blocked, pushed negative pressure ball 1 again, because exhaustor 6 is provided with check valve 4, so gas can only be discharged from exhaustor 6, and the gas in the external world can not enter spheroid from exhaustor, so aerofluxus is more thorough, and the negative pressure that obtains is bigger.Loose one's grip then, because the retraction force that spheroid self has, thereby in spheroid, producing negative pressure, intravital liquid just enters spheroid by drainage tube.
