CN2870848Y - Automatic safe negative-pressure suction bottle - Google Patents

Abstract

The utility model relates to an automatic safe negative-pressure suction bottle, belonging to the art of medical apparatus. The bottle consists of a bottle cap, a negative pressure tube, an induced tube and a float switch. The negative pressure tube and the induced tube are sealed and fixed on the bottle cap. The float switch is arranged on the negative pressure tube and can slide along the tube. The float switch is consisting of an opened cylinder cavity and a closed hemispherical cavity. The bottle would be full of negative pressure when the negative pressure is attracted by the tube. The induced tube would attract the liquid to the bottle from the sufferer. When the liquid surface touches the float switch, the float switch and the cylinder switch would slide up driven by the liquid. The conic rubber plug would fill into the down port of the negative pressure tube. The rubber plug would completely close the negative pressure tube under flotage and negative pressure. The negative pressure inside the tube would disappear and the induced tube would stop functioning. New attracting bottle would be replaced. The utility model has a plurality of advantages such as: reasonable designing, stable function, easy for use and sanitary.

Description

A kind of automatic safe vacuum suction bottle

Technical field

This utility model relates to a kind of automatic safe vacuum suction bottle, belongs to technical field of medical instruments.

Background technology

In hospital clinical operation, often use the vacuum suction bottle, common vacuum suction bottle in use after liquid often occurring and being filled, enters the situation in the negative pressure pipe, causes the negative pressure pipe contaminated, and the cleaning sterilization is wasted time and energy.

Summary of the invention

This utility model is at the deficiencies in the prior art, and the automatic safe vacuum suction bottle of negative pressure is provided after providing a kind of reasonable in design, easy to operate, liquid level to raise automatically.

The purpose of this utility model is achieved through the following technical solutions: a kind of automatic safe vacuum suction bottle, form by bottle cap, negative pressure pipe, drainage tube and buoyancy aid switch, the equal sealing and fixing of negative pressure pipe and drainage tube is on bottle cap, and the buoyancy aid switch is sleeved on the negative pressure pipe, and can slide on pipe.

Described buoyancy aid switch is made up of open cavity of garden cylindricality and hemispherical closed cavity, the garden, top of garden cylindricality cavity has a hole that is slidingly matched with the negative pressure pipe in the heart, the negative pressure pipe penetrates wherein, have several suction holes on the sidewall of garden cylindricality cavity, a taper rubber stopper is fixed at its heart place, garden, bottom surface, and its underpart is connected with the hemispherical hollow float.

When this utility model uses, air-breathing along with the negative pressure pipe, be negative pressure state in the suction bottle, drainage tube is attracted to liquid the suction bottle on one's body from the patient, when liquid level rises to the buoyancy aid position of the switch, ball float and garden cylindricality switch upwards slide, the taper rubber stopper is slowly filled in negative pressure pipe end opening, under the combined effect of buoyancy and negative pressure, the rubber stopper complete closed negative pressure pipe, negative pressure disappears in the suction bottle, and drainage tube quits work.Advantages such as that this structure has is reasonable in design, reliable, convenient health.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Wherein: 1, bottle cap, 2, the negative pressure pipe, 3, drainage tube, 4, the buoyancy aid switch, 5, rubber stopper, 6, suction hole.

The specific embodiment

Embodiment: structure as shown in drawings.Form by bottle cap 1, negative pressure pipe 2, drainage tube 3, buoyancy aid switch 4, rubber stopper 5, suction hole 6.Wherein, all sealing and fixing is on bottle cap 1 for negative pressure pipe 2 and drainage tube 3, and buoyancy aid switch 4 is sleeved on the negative pressure pipe 2, and can slide on pipe.Buoyancy aid switch 4 is made up of the open cavity and the hemispherical closed cavity of a garden cylindricality, the garden, top of garden cylindricality cavity has a hole that is slidingly matched with the negative pressure pipe in the heart, negative pressure pipe 2 penetrates wherein, and be provided with positioning boss endways, make the buoyancy aid switch hang down the state retaining under gravity at the positioning boss place, can not landing.Have several suction holes 6 on the sidewall of garden cylindricality cavity, a taper rubber stopper 5 is fixed at its heart place, garden, bottom surface, and its underpart is connected with the hemispherical hollow float.During use, air-breathing along with the negative pressure pipe is negative pressure state in the suction bottle, drainage tube is attracted to liquid the bottle on one's body from the patient, when liquid level rises to the buoyancy aid switch, liquid buoyancy promotes ball float and garden cylindricality switch upwards slides, and the taper rubber stopper is slowly filled in negative pressure pipe end opening, under the combined effect of buoyancy and negative pressure, the rubber stopper complete closed negative pressure pipe, negative pressure disappears in the suction bottle, and drainage tube quits work, the suction bottle that is more renewed by medical personnel.

Claims (2)

1, a kind of automatic safe vacuum suction bottle is characterized in that, is made up of bottle cap, negative pressure pipe, drainage tube and buoyancy aid switch, and the equal sealing and fixing of negative pressure pipe and drainage tube is on bottle cap, and the buoyancy aid switch is sleeved on the negative pressure pipe, and can slide on pipe.

2, a kind of automatic safe vacuum suction bottle according to claim 1, it is characterized in that, described buoyancy aid switch is made up of the open cavity and the hemispherical closed cavity of garden cylindricality, the garden, top of garden cylindricality cavity has a hole that is slidingly matched with the negative pressure pipe in the heart, the negative pressure pipe penetrates wherein, have several passages on the sidewall of garden cylindricality cavity, a taper rubber stopper is fixed at its heart place, garden, bottom surface, and its underpart is connected with the hemispherical hollow float.
