Description
Technical field
This utility model relates to a kind of blood internal medicine bone marrow draw-out device, belongs to blood internal medicine medical apparatus technical field.
Background technology
At present, in blood internal medicine, while checking for patient, except needs extract blood testing, also often need to chemically examine for patient's bone marrow extraction liquid.Bone marrow extraction liquid, often first will burrow with puncture needle, and then, the suction pipe absorption bone marrow fluid that puts in, this work completes in two steps, easily causes twice misery of patient.And because general puncture needle is with sensation operation, repeatable poor, cannot carry out quantitatively.Simultaneously suction pipe is drawn bone marrow fluid, also just qualitative, cannot carry out quantitatively, this just caused may analyze inaccurate, and cannot standardization, poor repeatability, has caused some deviations to analysis.If in the process extracting at bone marrow fluid, adopt some reasonable modes, be conducive to carry out bone marrow fluid sampling for patient, also convenient inspection.
Utility model content
The purpose of this utility model is to overcome the defect of above-mentioned technology, provide a kind of can be for patient's bone marrow extraction liquid once, after burrowing, puncture needle utilize the suction pipe being arranged on wherein to draw bone marrow fluid simultaneously, and carry out quantitatively for punching and absorption, so that repetitive operation better checks for patient.
To achieve these goals, the technical solution of the utility model is as follows.A blood internal medicine bone marrow draw-out device, comprises hydraulic cavities, liquid storage cylinder, suction pipe, storage box and puncture needle, wherein, is provided with hydraulic piston in hydraulic cavities, is provided with push rod in hydraulic piston; Hydraulic cavities bottom is provided with liquid storage cylinder, between hydraulic cavities and liquid storage cylinder, is provided with dividing plate; Liquid storage cylinder bottom is provided with puncture needle, is provided with suction pipe in puncture needle; On storage box, being provided with connection tube is connected with bottom, liquid storage cylinder side.
Further, push rod top is through hydraulic cavities arranged outside jug, and push rod bottom is provided with suction piston.
Further, top, hydraulic cavities side is connected with liquid line, the external liquid of liquid line, and be provided with switch, can move downward to promoting for liquid hydraulic piston in hydraulic cavities.
Further, on suction pipe, be provided with suction pipe scale, be conducive to observe the liquid scale of sucking-off; Suction pipe bottom is circular configuration, is convenient to imbitition in human body; Suction pipe bottom is also provided with sipper pore, is convenient to draw bone marrow fluid from multiple directions in human body.
Further, on puncture needle, be provided with puncture needle scale, be convenient to observe the degree of depth that puncture needle enters human body; Puncture needle bottom is provided with and horizontal plane inclined-plane in angle of 45 degrees, is convenient to penetrate into inside of human body.
The beneficial effect of this utility model is: this utility model, by suction pipe is set in puncture needle, can complete the operation that burrows and draw bone marrow fluid once, has reduced patient's misery, and has saved the working time, has improved efficiency.On puncture needle and suction pipe, be labeled with scale, be convenient to repetitive operation, be also convenient to quantitative analysis, in suction pipe bottom, be provided with pore simultaneously, be convenient to draw bone marrow fluid from all directions, be convenient to the accuracy of analyzing simultaneously., be also provided with storage box and preserve for bone marrow fluid, to reduce as far as possible pollution, strengthen verity and the reliability of testing data.

The specific embodiment
Below in conjunction with accompanying drawing, further set forth the specific embodiment of this utility model.
Blood internal medicine bone marrow draw-out device, comprises hydraulic cavities 1, liquid storage cylinder 4, suction pipe 5, storage box 8 and puncture needle 10 as shown in Figure 1, wherein, is provided with hydraulic piston 15 in hydraulic cavities 1, is provided with push rod 14 in hydraulic piston 15; Hydraulic cavities 1 bottom is liquid storage cylinder 4, between hydraulic cavities 1 and liquid storage cylinder 4, is provided with dividing plate 13; Liquid storage cylinder 4 bottoms are provided with puncture needle 10, are provided with suction pipe 5 in puncture needle 10; On storage box 8, being provided with connection tube 7 is connected with liquid storage cylinder 4 bottoms, side.
Wherein, push rod 14 tops are through hydraulic cavities 1 arranged outside jug 2, and push rod 14 bottoms are provided with suction piston 12.Hydraulic cavities 1 top, side is connected with liquid line 3, the external liquid of liquid line 3, and be provided with switch, can move downward to promoting for liquid hydraulic piston 15 in hydraulic cavities 1.On suction pipe 5, be provided with suction pipe scale 6, be conducive to observe the liquid scale of sucking-off; Suction pipe 5 bottoms are circular configuration, are convenient to imbitition in human body; Suction pipe 5 bottoms are also provided with sipper pore 11, are convenient to draw bone marrow fluid from multiple directions in human body.On puncture needle 10, be provided with puncture needle scale 9, be convenient to observe the degree of depth that puncture needle 10 enters human body; Puncture needle 10 bottoms are provided with and horizontal plane inclined-plane in angle of 45 degrees, are convenient to penetrate into inside of human body.
