Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a medical waste liquid filtering device.
Background
In a hospital, waste liquid such as sputum, effluent blood, urine and the like which are spitted by a patient are uniformly contained in a plastic barrel, a waste liquid inlet and a waste liquid outlet are formed in the plastic barrel, and the waste liquid needs to be treated after the waste liquid in the plastic barrel is fully collected; when in treatment, a liquid discharge pipe is connected to a waste liquid discharge port on the plastic barrel, a filter device is arranged on the liquid discharge pipe, and the filter device is communicated with a suction apparatus (used for sucking and removing bleeding, exudates, purulent liquid and the like in the operation); then the suction apparatus is started to generate suction force, and waste liquid in the plastic barrel is sucked into the liquid discharge pipe, passes through the filtering device and enters the suction apparatus.
The filter equipment who uses now mainly includes the cylinder bucket, and the top intercommunication of cylinder bucket has the fluid-discharge tube, and the bottom intercommunication of cylinder bucket has the feed liquor pipe, is equipped with the cassette in the cylinder bucket, is equipped with a plurality of filtration through-holes on the cassette, the lateral wall of cassette and the inner wall laminating of cylinder bucket and the inner wall fixed connection of cylinder bucket. When such a filtering apparatus is used for treating waste liquid, there is a problem that: because contain material such as blood in the waste liquid, the in-process that blood held can form blood stain, blood stain will block up the filtration through-hole on the cassette when passing through the cassette, filtration rate will become slow when will leading to handling waste liquid like this, and still need change the cassette after blockking up, and adopt fixed connection's mode, it is just very inconvenient to change the cassette, and the cassette that can not timely observation is blockked up, just so can not carry out timely change to the cassette, and then the timeliness that leads to waste liquid processing work can not be the handle accuse.
Disclosure of Invention
The invention aims to provide a medical waste liquid filtering device to solve the problem that a filter disc cannot be timely found to be blocked when waste liquid is filtered in the prior art.
In order to solve the technical problems, the invention provides the following technical scheme: a medical waste liquid filtering device comprises a transparent rectangular filtering box, wherein a box cover is arranged on the filtering box, the bottom of the filtering box is connected with a liquid inlet pipe, the box cover is connected with a liquid discharge pipe, a first bump is arranged on one side wall of the filtering box, a first limiting groove is formed in the first bump and communicated with the filtering box, a first elastic piece is arranged in the first limiting groove, a second bump is arranged on the other side wall of the filtering box, a second limiting groove is formed in the second bump and communicated with the filtering box, and a second elastic piece is arranged in the second limiting groove; the first elastic piece and the second elastic piece are both connected with abutting blocks, a filter disc is arranged in the filter box, a plurality of through holes are formed in the filter disc, elastic bulges are arranged on the side wall of the filter disc, and the elastic bulges are in contact with the inner wall of the filter box and are in sliding connection with the inner wall of the filter box; the side walls of the two abutting blocks are provided with clamping grooves matched with the protrusions, and the filter sheet is located between the two abutting blocks when the first elastic piece and the second elastic piece are in a compressed state.
The working principle of the invention is as follows:
when the medical waste liquid filtering device is used, firstly, a liquid inlet pipe at the bottom of a filtering box is communicated with a plastic barrel for containing waste liquid, a liquid discharge pipe on a box cover at the top of the filtering box is communicated with an aspirator, then the aspirator is started, because a first elastic piece and a second elastic piece are in a compressed state, a filtering sheet in the filtering box is positioned between two abutting blocks, an elastic bulge is arranged on the side wall of the filtering sheet, clamping grooves matched with the bulges are formed in the two abutting blocks, the filtering sheet is abutted by the two abutting blocks when positioned between the two abutting blocks, then the waste liquid enters the filtering box through the liquid inlet pipe and finally enters the aspirator through the liquid discharge pipe after passing through the filtering sheet, and blood stains in the waste liquid can be blocked by the filtering sheet; when the through holes on the filter disc are smooth, the aspirator sucks air and waste liquid in the space above the filter disc when working, so that the air pressure above the filter disc is lower than that below the filter disc, at the moment, the waste liquid below the filter disc can quickly enter the upper part through the through holes on the filter disc for replenishment, so that the adsorption force required to be born by the filter disc is reduced, the filter disc is prevented from being sucked away along with the waste liquid, when filtering for a long time, the through holes on the filter disc can be blocked by impurities such as blood stains, when the aspirator continues to suck, because the through holes on the filter disc are blocked by most or all of the through holes, a large amount of waste liquid below the filter disc cannot enter the upper part of the filter disc for replenishment, so that the adsorption force generated when the aspirator works, most or all of the waste liquid needs to be born by the filter disc for a long time, and the filter disc can be sucked out from the space, and the first elastic piece in the first limiting groove and the second elastic piece in the second limiting groove can simultaneously pop the abutting block out to form a partition plate for separating the filter box, so that the waste liquid is prevented from being sucked away by the suction apparatus without being filtered.
The invention has the beneficial effects that:
when adopting the scheme to filter waste liquid, in the long-time filtering process, when through-hole blocking on the filter disc is gone up to impurity such as blood stain in the waste liquid, the waste liquid of filter disc below is difficult to be supplemented with a large amount of tops that enter into the filter disc this moment, and then make the adsorption affinity that the aspirator during operation produced, most or whole need the filter disc to bear for a long time, again because be equipped with elastic arch on the lateral wall of filter disc, two are supported and all be equipped with the draw-in groove that matches with the arch on the piece, will make elastic arch take place deformation in the draw-in groove like this, and then the filter disc will follow two and support and pop out between the piece, and the rose box is transparent again, consequently, just can be timely observe that the filter disc is blockked up, just so can be timely change of carrying out the filter disc, and the processing work of waste liquid also can be better hold ageing.
The optimization of the basic technical scheme is as follows:
further, the protrusion is an arc protrusion. The bulge is an arc bulge, so that the filter plate can be conveniently popped up when the filter plate is blocked, and the blockage of the filter plate can be known as soon as possible.
Furthermore, the filter box is sleeved with a transparent cylindrical sleeve. This facilitates protection of the filter box and the sleeve is transparent and does not affect the monitoring within the filter box.
Further, the first elastic piece and the second elastic piece are both springs. The spring is simple in structure, convenient to produce and process and capable of greatly saving production cost.
Further, the case lid can be dismantled with the rose box and be connected. It is more convenient when needing to change the filter plate.
Further, the case lid and rose box threaded connection. The threaded connection mode has a simple structure and is convenient to produce and process.
