the bone marrow collecting and filtering device comprises a filter and a filter screen, wherein the filter comprises a filter cylinder, a filter cone cylinder and a filter pipe which are sequentially arranged from top to bottom; the filter screen is movably inserted into the bottom of the filter cartridge, and a handle is arranged on the filter screen.

Preferably, the drainage device comprises a drainage cylinder and a drainage hose, the drainage cylinder comprises a connecting cylinder, a connecting cone cylinder and a connecting pipe which are sequentially arranged from bottom to bottom, an internal thread is arranged on the connecting cylinder, the internal thread is matched with an external thread on the filter pipe, and the connecting cylinder is arranged on the filter pipe through a thread; the drainage hose is respectively connected with the connecting pipe and the infusion bag.

Wherein, the connecting pipe is provided with an inclined opening.

Compared with the prior art the utility model discloses following beneficial effect has:

the bone marrow collecting and filtering device provided by the utility model filters collected bone marrow, removes thrombus, fat and the like, is not easy to block pipelines, is convenient to use and reduces the waste of bone marrow; the bone marrow filter can be directly connected with an infusion bag, and the filtered bone marrow is directly injected into the infusion bag, so that the flow is reduced, the bone marrow extraction efficiency is improved, and the operation time is shortened.

Drawings

FIG. 1 is a schematic view of a bone marrow collecting and filtering device;

fig. 2 is a schematic structural view of the filter screen.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Example one

As shown in fig. 1 and 2, a bone marrow collecting and filtering device comprises a filter 1 and a filter screen 2 which are both made of stainless steel, wherein the filter 1 comprises a filter cartridge 11, a filter cone 12 and a filter pipe 13, the filter cartridge 11, the filter cone 12 and the filter pipe 13 are sequentially arranged from top to bottom, the diameters of the filter cartridge 11, the filter cone 12 and the filter pipe 13 are sequentially reduced, the filter screen 2 is movably inserted at the bottom of the filter cartridge 11, and a handle 3 is arranged on the filter screen 2; wherein cartridge filter 11 is used for depositing the marrow, and the marrow enters into conical filtration awl section of thick bamboo 12 after passing through filter screen 2 filters, then flows out through filter tube 13, and filtration awl section of thick bamboo 12 can realize the reducing, makes things convenient for filter screen 2's fixed simultaneously. The filtering tube 13 is used to connect with a container, collect filtered bone marrow, and inject the filtered bone marrow into an infusion bag.

The filter screen 2 can adopt the existing stainless steel filter screen 2, and can also adopt a mesh plate made of a stainless steel plate. The handle 3 is convenient for dismounting the filter screen 2.

Stainless steel is adopted, so that the cleaning and the high-temperature disinfection are convenient; the filter 1 can also be made of plastic, and the filter 1 made of plastic can be used only once.

More bone marrow can be deposited in the filter cartridge 11, and the filter screen 2 filters out thrombus, fat and other larger particles in the bone marrow, so that the pipeline is prevented from being blocked, the waste of the bone marrow is reduced, the extraction speed of the bone marrow is increased, and the operation time is shortened.

When the bone marrow filter is used, the bone marrow extracted from the syringe is injected into the filter cylinder 11, and the filter screen 2 filters the bone marrow. When more thrombus and fat appear on the filter screen 2, the filter screen 2 can be taken out through the handle 3, and the filter screen 2 is prevented from being blocked after the thrombus and the fat are removed.

Example two

On the basis of above-mentioned embodiment one, as shown in fig. 1, still include drainage device, drainage device includes drainage tube 4 and drainage hose 5, and drainage device detachable installs on filter 1, makes things convenient for the dismouting, is convenient for wash and high temperature disinfection, and drainage device is direct to pour into the infusion bag with the marrow after filtering into, need not to shift the infusion bag with the marrow through the cylinder once more in, has improved efficiency, has reduced the flow. Specifically, the drainage cylinder 4 comprises a connecting cylinder 41, a connecting cone cylinder 42 and a connecting pipe 43, the connecting cylinder 41, the connecting cone cylinder 42 and the connecting pipe 43 are sequentially arranged from top to bottom in length, and the diameters of the connecting cylinder 41, the connecting cone cylinder 42 and the connecting pipe 43 are sequentially reduced, wherein an internal thread is arranged on the connecting cylinder 41 and matched with an external thread on the filter pipe 13, and the connecting cylinder 41 is installed on the filter pipe 13 through a thread; the connecting cone cylinder 42 is conical, so that reducing is realized. The connecting pipe 43 is provided with an inclined opening 44, the inclined opening 44 is convenient for being arranged in the drainage hose 5, and meanwhile, the excellent flow guiding effect can be carried out, so that the bone marrow is prevented from being gathered on the outlet of the connecting pipe 43. The drainage hose 5 is connected with the infusion bag, and the filtered bone marrow is directly injected into the infusion bag, so that the efficiency is improved, and the operation time is shortened.
