Description
Technical field
The utility model belongs to medical instruments field, particularly relates to a kind of Semiautomatic device for collecting marrow.
Background technology
Existing device for collecting marrow is for the sampling observation to stem cell or myeloid tissue mostly, usually by sleeve pipe needle stand, puncture needle, nook closing member and syringe composition, the general step of this type of harvester is used to be first inserted by nook closing member in sleeve pipe marrow puncture needle, make nook closing member most advanced and sophisticated concordant with bone marrow aspiration syringe needle, after puncture needle puts in place, extract nook closing member again, change the extraction that syringe carries out stem cell, this kind of device is generally used for the extraction to a small amount of stem cell, when a large amount of bone marrow extraction stem cell, efficiency is very low, inapplicable, and, in the marrow gathered containing a large amount of by fat drop, hematopoiesis island cell mass, the marrow small particle of macrophage and fibrocyte composition, if do not filtered, easily the complication such as embolism are caused after in direct input patient body, existing device for collecting marrow does not possess filtering function, must filter separately.
Utility model content
The purpose of this utility model is to provide a kind of Semiautomatic device for collecting marrow, be intended to solve existing device for collecting marrow a large amount of gather marrow time inefficiency, do not possess filtering function.
The utility model is achieved in that a kind of Semiautomatic device for collecting marrow comprises nook closing member, negative pressure pump, collection tube, filter, blood taking bag, control panel; Described nook closing member is connected with negative pressure pump, and negative pressure pump is connected with collection tube by flexible pipe, and collection tube is connected with filter by flexible pipe, and filter is connected with blood taking bag by flexible pipe.
Further, described collection tube is made up of the first collection tube and second collection tube two parts, and be provided with check valve between the first collection tube and the second collection tube, the first collection tube is communicated with negative pressure pump, second collection tube is connected with filter, and the second collection tube is also provided with and pushes away handle.
Further, described control panel is provided with action button for setting suction strength and negative pressure time and for the display screen of marrow weight showing acquisition time and collect.
Further, described filter is Cylindrical filter device, and the bottom of filter is provided with a flow-guiding mouth and a leakage fluid dram, and flow-guiding mouth is connected by flexible pipe with blood taking bag.
Further, described filter inside is provided with at least two screen packs from top to bottom, and the mesh of screen pack reduces from top to bottom successively.
effect gathers
Semiautomatic device for collecting marrow of the present utility model gathers marrow by negative pressure, overcome existing harvester ineffective problem when a large amount of collection marrow, decrease wound when gathering marrow, patient caused, have filtration concurrently, avoid outside contamination.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Semiautomatic device for collecting marrow that the utility model embodiment provides;
In figure: 1, nook closing member; 2, negative pressure pump; 3, collection tube; 4, filter; 5, blood taking bag; 6, control panel; 7, handle is pushed away.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 shows the structure of Semiautomatic device for collecting marrow of the present utility model, as shown in the figure, the utility model is achieved in that a kind of Semiautomatic device for collecting marrow comprises nook closing member 1, negative pressure pump 2, collection tube 3, filter 4, blood taking bag 5, control panel 6; Described nook closing member 1 is connected with negative pressure pump 2, and negative pressure pump 2 is connected with collection tube 3 by flexible pipe, and collection tube 3 is connected with filter 4 by flexible pipe, and filter 4 is connected with blood taking bag 5 by flexible pipe.
Further, described collection tube 3 is made up of the first collection tube and second collection tube two parts, and be provided with check valve between the first collection tube and the second collection tube, the first collection tube is communicated with negative pressure pump, second collection tube is connected with filter, and the second collection tube is also provided with and pushes away handle 7.
Further, described control panel 6 is provided with action button for setting suction strength and negative pressure time and for the display screen of marrow weight showing acquisition time and collect.
Further, described filter 4 is Cylindrical filter device, and the bottom of filter 4 is provided with a flow-guiding mouth and a leakage fluid dram, and flow-guiding mouth is connected by flexible pipe with blood taking bag 5.
Further, described filter 4 inside is provided with at least two screen packs from top to bottom, and the mesh of screen pack reduces from top to bottom successively.
Control panel 6 sets negative pressure pressure and negative pressure time, carry out bone marrow aspiration, start negative pressure pump 2, the marrow of absorption enters the second collection tube, after setting-up time has arrived through the first collection tube, promotion pushes away handle 7, closed check valve between first collection tube and the second collection tube, marrow enters filter 4 through the second collection tube, and the marrow after filtration enters blood taking bag through flow-guiding mouth, clean to injecting normal saline in filter by syringe, the liquid of cleaning is discharged through leakage fluid dram.
Semiautomatic device for collecting marrow of the present utility model gathers marrow by negative pressure, overcome existing harvester ineffective problem when a large amount of collection marrow, decrease wound when gathering marrow, patient caused, have filtration concurrently, avoid outside contamination.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that performing creative labour can make still within protection domain of the present utility model.
