Patent Application
20110198353
The present invention relates to a waste liquid guide device with a quickly replaceable inner bag, in that a pressure release valve is installed to a bottle body. Air can enter into a vacuum between an inner bag and the bottle body so that the inner bag is compressed, then the inner bag and a cover release from the bottle body quickly for taking out the inner bag.
Referring to
However, the prior art has the following disadvantages. When it is desired to update the inner bag, the negative pressure device must close and open the pressure release valve. After the pressure descends, the inner bag is taken out. The process is tedious.
The object of the present invention is to provides a waste liquid guide device with a quickly replaceable inner bag, comprising: a bottle body having an inner bag; a cover installed with a waster liquid guide tube, two vacuum suction holes, a tube head, a handle, an annular groove, a check valve, a unidirectional valve; the inner bag is coupled to the annular groove; wherein the unidirectional valve is connected to the two vacuum suction holes; the check valve is communicated to the waste liquid guide hole; the tube head is communicated to the two vacuum suction holes; the inner bag is connected to the cover and is engaged to the annular groove; and a pressure release valve installed to the bottle body. Thus a waste liquid guide device with a quickly replaceable inner bag is formed. The inner bag can be replaced quickly without stopping other instrument.
In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With reference to
A bottle body 29 has an inner bag 28.
A cover 20 is installed with a waster liquid guide tube 21, two vacuum suction holes 22, a tube head 23, a handle 24, an annular groove 25, a check valve 26, a unidirectional valve 27. The inner bag is coupled to the annular groove 25.
A bottom of the bottle body 29 has a pressure release valve 30 which is formed by a nut 301, a washer 302, an outer thread 303, an elastic element 304 and a pressing portion 305. The pressure release valve 30 installed at a bottom of the bottle body 29. The pressure release valve 30 is screwed to the bottle body 29 by the nut 301 and the outer thread 303. The washer 302 serves to isolate air. The elastic element 304 is installed between the pressing portion 305 and the bottle body 29. A part of the elastic element 304 is in tense state so that the washer 302 serves to seal the gap between the bottle body 29 and the pressure release valve 30. In use, a negative pressure is built in the vacuum suction holes 22 so as to such the air in the inner bag 28 and the bottle body 29 so that air pressure in the inner bag 28 and the bottle body 29 is smaller than atmosphere pressure. Then the undesired liquid at a hurt area of a patient can be guided to the waster liquid guide hole 21 to the inner bag 28. When the inner bag 28 is filled with the waste liquid. The pressure release valve 30 is pressed and then air enters into the bottle body 29. The inner bag 28 is compressed by air so that the inner bag 28 and the cover 20 are released from the bottle body 29. Therefore, it can be taken out quickly. Thereby, a waste liquid guide device with a quickly replaceable inner bag is formed.

Advantages of the present invention are that:
1. When updating the inner bag, the pressure release valve is pressed and a guide tube of a negative pressure device is pulled out for updating the inner bag.
2. During the process of updating, the pressure release valve is pressed for updating the inner bag. The process is quick and the conveniently.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
