Description

Can dismantle solid-liquid separation collection device

Technical Field

The utility model relates to a solid-liquid separation equipment especially relates to a can dismantle solid-liquid separation collection device.

Background

With the development of medical technology, surgery has become the most common treatment in medicine today. In surgical operation, the focus tissue is inevitably cut and cleaned, and the cut focus tissue is called pathological tissue specimen, which is an important basis for determining pathological diagnosis and plays an important role in determining medical diagnosis, so that the method has great significance for reasonably collecting and storing the pathological tissue specimen. For some surgical operations, medical staff need to continuously wash a wound cavity of a patient and collect the washing liquid during the operation of the patient, and simultaneously separate a pathological tissue specimen or wash and remove stones. In the prior art, the collection of the body cavity flushing fluid in the operation process is mainly completed by matching a doctor on an operating table with a circulating nurse under the operating table, and the flushing fluid in the cavity of the patient is sucked by using a negative pressure suction tube. The above process requires a good cooperation tacit between medical care, otherwise, the problems that the washing liquid cannot be received, splashed and polluted due to improper operation may occur, the pathological diagnosis is affected, and the like, the whole washing liquid collecting process is not only labor-consuming, but also incomplete separation of the samples in the washing liquid may occur, so that the subsequent operation is affected.

Therefore, in order to overcome the above problems, there is a patent application "a negative pressure suction filtration and collection device (CN 210750456U)" comprising a drainage bucket and a detachable solid-liquid separation device; the drainage barrel comprises a drainage barrel shell and a negative pressure cover which are connected in a sealing way, the upper end surface of the negative pressure cover is respectively provided with a negative pressure pipe interface and a solid-liquid separation device mounting port, and the lower end surface of the negative pressure cover is connected with a bag body in a sealing way; the detachable solid-liquid separation device comprises a detachable solid-liquid separation pipe and an end cover, the detachable solid-liquid separation pipe consists of two solid-liquid separation pipe sub-pipes, the upper end of the detachable solid-liquid separation pipe is clamped with the end cover, and the end cover is arranged on a mounting port of the solid-liquid separation device and is in sealing connection with the mounting port of the solid-liquid separation device; the upper end surface of the end cover is provided with a solid-liquid separation tube suction tube communicated with the detachable solid-liquid separation tube.

However, the structure is complex, the separated liquid is sucked out by negative pressure from the upper part, and as a result, a part of flushing liquid is often left in the bottle body, and the solid-liquid separation cannot be completely realized. And the solid-liquid separation pipe is required to be rigid, so that the volume of tissues and the like which can be separated is limited, and the solid-liquid separation pipe is cleaned and disinfected subsequently, so that the whole process is complicated, and the workload of medical personnel is increased.

Disclosure of Invention

The utility model provides a detachable solid-liquid separation device which has simple structure, can directly sample after the operation is finished, has large volume of stored separated contents, and omits complicated operations such as filtration, precipitation, collection and the like; the technical problems of complex structure, complex operation process and limited storage volume of the solid-liquid separation device in the prior art are solved.

The above technical problem of the present invention is solved by the following technical solutions: the utility model provides a can dismantle solid-liquid separation collection device, includes the bottle, is equipped with the bottle lid in the top of bottle, is equipped with the import pipe in the top of bottle lid, is equipped with the flush fluid outlet pipe in the below of bottle, is equipped with flexible filter screen in the bottle and collects the bag, the import pipe extend to in the bottle, take the filter screen to collect the bag and fix in importing the pipe. The collecting device is generally matched with medical instruments such as a sheath, a planer, a negative pressure vacuum pump and the like. In the operation process, collection device is under the effect of negative pressure, and in calculus, the human tissue that the patient internal was smashed entered into collection device along with the flush fluid, the filtration of bag is collected to the filter screen, and the flush fluid is along with the export suction, and calculus and human tissue are retained in the filter screen and are collected the bag. Calculus and/or tissue in the filter screen collecting bag, under the effect of negative pressure, the flush fluid has been taken out from, has saved loaded down with trivial details operations such as filtration, sediment, collection, only needs to unscrew the bottle lid, cuts open the filter screen collecting bag and can take a sample the chemical examination. The utility model discloses a collection device changes the below of placing the bottle in with the flush fluid export, under the dual function of gravity and negative pressure appeal, the flush fluid can be taken out completely from, just so can not leave partly flush fluid in the bottom of the bottle, accomplishes complete solid-liquid separation. And adopt flexible filter screen to collect the bag, can furthest's filtration calculus or organize the thing, can carry out volume change according to the object in the filter screen, let fixed collection space utilization reach the biggest. The entire collection device may be a single use medical device.

Preferably, the inner wall of the bottle body is provided with a spacing strip. Collect the bag at the filter screen and collect the in-process, calculus, tissue collect the bag along with the flush fluid entering filter screen, if let the filter screen collect the bag and hug closely with the bottle inner wall, then can make solid-liquid separation slow. If let the filter screen collect the bag and block up bottom flush fluid export, then will make the operation difficult to go on, consequently prevent stifled parting strip and can effectively separate the clearance between filter screen and the bottle inner wall, guarantee the solid-liquid separation effect.

Preferably, the bottle cap is detachably connected with the bottle body, and a sealing ring is arranged between the bottle cap and the bottle body. The filter screen collecting bag in the bottle body is convenient to take out, and the filter screen collecting bag can be cut off for sampling and assay. The sealing ring can be ensured to be sealed, so that the solid-liquid separation can be rapidly realized under the action of negative pressure suction.

Preferably, a baffle is fixed on the inlet pipe, and the filter screen collecting bag is fixed on the wall of the inlet pipe above the baffle. The baffle can prop up the filter screen upper end, lets in solid matter etc. enter into the filter screen collection bag easily, and it is fixed also to make things convenient for the filter screen collection bag moreover.

Preferably, the outlet pipe is connected with a negative pressure suction structure through a hose. The negative pressure pumping structure comprises a liquid collecting tank, a liquid inlet and a negative pressure port are arranged above the liquid collecting tank, the liquid inlet is connected with an outlet pipe through a pipeline, and the negative pressure port is connected to a vacuum pump through a pipeline. Liquid is retained in the liquid collecting tank, and the negative pressure port is vacuumized to complete solid-liquid separation.

Preferably, the outer wall of the bottle body is provided with an integrally formed hook. The collecting device is conveniently hung on the trolley, and the operation is convenient.

Therefore, the rigid electronic endoscope of the present invention has the following advantages: the structure is simple, the solid-liquid separation effect is good, no accumulated liquid is left below the bottle body, and the flexible filter screen collecting bag can ensure the maximum bottle body utilization rate; after the bottle body is separated from the bottle cap, the filter screen collecting bag is directly cut open to complete sampling and testing, the steps are few, and the operation is simple.
