Abstract
The utility model discloses a negative-pressure drainage device, which consists of a negative-pressure suction tube, a drainage tube, a rubber bottle stopper, a drainage bottle and a spherical float, wherein the rubber bottle stopper is arranged on the drainage bottle; one end of the negative-pressure suction tube and one end of the drainage tube penetrate through the rubber bottle stopper, and are led into the drainage bottle; a tapered opening is formed in the tail end of the negative-pressure suction tube; the spherical float is arranged in the drainage bottle; the diameter of the spherical float is equal to the maximum diameter of the tapered opening in the tail end of the negative-pressure suction tube. According to the negative-pressure drainage device, the spherical float enters the tapered opening in the tail end of the negative-pressure suction tube to stop negative-pressure suction under the action of liquid buoyancy and negative-pressure suction force when the liquid level of drainage liquid reaches the height of the negative-pressure suction tube in a negative-pressure suction process, so that the loss of negative-pressure suction meter can be effectively prevented, and the medical cost can be lowered; in addition, the negative-pressure drainage device is easy to operate and low in cost, and has practical value.
Description
Technical field
This utility model relates to field of medical article technology, is a kind of negative pressure drainage device concretely.
Background technology
Vacuum suction drainage bottle is a kind of conventional medical apparatus and instruments, is a kind of device secretions in body, drainage-fluid being excreted by negative pressure.The vacuum suction drainage bottle of prior art is to be taken over and directly connected patient and drainage bottle by drain, therefore, in the time that drainage-fluid liquid reaches negative-pressure suction pipe, there will be drainage-fluid to arrive negative pressure drainage table along negative pressure, lose drainage, loss that simultaneously can build-up of pressure table.
Summary of the invention
In sum, the purpose of this utility model is to provide a kind of negative pressure drainage device.
The purpose of this utility model realizes by following technology:
A kind of negative pressure drainage device, is made up of negative-pressure suction pipe, drainage tube, rubber bottle cover, drainage bottle and spherical float, and drainage bottle is provided with rubber bottle cover; Introduce in drainage bottle through rubber bottle cover one end of negative-pressure suction pipe and drainage tube; Negative-pressure suction pipe end is tapered opening.
In above-mentioned drainage bottle, be provided with 1 spherical float.
The diameter of above-mentioned spherical float equates with the tapered opening maximum gauge of negative-pressure suction pipe end.
1, this utility model is in vacuum suction process, in the time that the liquid level of drainage-fluid arrives the height of negative-pressure suction pipe, spherical float enters the tapered opening of negative-pressure suction pipe end under the effect of liquid surface-floated and negative pressure suction force, and vacuum suction stops, and prevents that drainage-fluid from rising to vacuum table with negative pressure.
2, this utility model is in vacuum suction process, in the time that spherical float stops up the tapered opening of negative-pressure suction pipe end, and replaceable drainage bottle, and spherical float is inserted in drainage bottle again, restart work.
3, this utility model is simple to operate, cost is low, with practical value.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
As shown in Figure 1, a kind of negative pressure drainage device, is made up of negative-pressure suction pipe 1, drainage tube 2, rubber bottle cover 3, drainage bottle 5 and spherical float 6, and drainage bottle 5 is provided with rubber bottle cover 3; One end of negative-pressure suction pipe 1 and drainage tube 2 is placed in drainage bottle 5 through rubber bottle cover 3; Negative-pressure suction pipe 1 end is tapered opening 4.
In drainage bottle 4, be provided with 1 spherical float 6.
The diameter of spherical float 6 equates with tapered opening 4 maximum gauges of negative-pressure suction pipe 1 end.
Embodiment
In vacuum suction process, negative-pressure suction pipe 1 is connected with vacuum table, drainage tube 2 is connected with the body fluid connecting device of needs of patients drain, negative-pressure suction pipe 1 and drainage tube 2 are extended to drainage bottle 4 by rubber bottle cover 3 simultaneously, interior placement one spherical float 6 of drainage bottle 4, regulate pressure setting, start working, in the time that the liquid level of drainage-fluid arrives the height of negative-pressure suction pipe, spherical float enters the tapered opening of negative-pressure suction pipe end under the effect of liquid surface-floated and negative pressure suction force, and vacuum suction stops, and prevents that drainage-fluid from rising to vacuum table with negative pressure; Now closing presure, replaceable drainage bottle, and spherical float is inserted in drainage bottle again, restart work.
