Abstract
The invention discloses a blood bacterium collecting device. The blood bacterium collecting device is characterized by comprising a blood flowing-in tube, a blood flowing-out tube, a first cavity, a first power wheel, a second cavity, a second power wheel and a bacterium collector. The blood flowing-in tube, the first cavity and the blood flowing-out tube are sequentially communicated, and the first power wheel and the second cavity are formed in the two sides of the first cavity respectively. The first cavity and the second cavity are isolated through an isolating diaphragm. A through hole is formed in the isolating diaphragm, and the diameter of the through hole is 1.0 micron-1.7 microns. One end of the second cavity is connected with an extending cavity connected to the blood flowing-out tube, the bacterium collector is arranged on the extending cavity, the pore diameter of an outlet of the bacterium collector is 0.10 micro-0.32 micro, and the second power wheel is arranged on one side of the extending cavity, and needle heads are installed at the inlet end of the blood flowing-in tube and the outlet end of the blood flowing-out tube. The structure is simple, the manufacturing cost is low, the using cost of a patient is reduced, the blood can flow back to the human body, and the blood loss is reduced.
Description
Technical field
The present invention relates to a kind of medical apparatus, particularly a kind of blood antibacterial gathering-device.
Background technology
Existing clinical treatment field, patient to suspecting that antibacterial infects, often will repeatedly cultivate in order to increase positive rate, conventionally need to gather 2-3 cover hemoculture (blood sampling volume is conventionally more than 60ml), this is a heavy body burden for anemia patient or child.Therefore how rationally and the hemoculture expense eighteenth of the twenty is expensive, this has also brought very large economic pressures to patient,, the antibacterial in enrichment patient blood is current this area institute problem demanding prompt solution economically.
Summary of the invention
The object of the invention is to overcome blood antibacterial in prior art and collect that the blood loss existing is large, the problem of both expensive, and provide a kind of reasonable in design, the blood antibacterial gathering-device that blood loss is few, cost of use is low.
The present invention addresses the above problem adopted technical scheme:
A kind of blood antibacterial gathering-device, it is characterized in that: comprise blood flow inlet pipe, blood effuser, the first cavity, the first power wheel, the second cavity, the second power wheel, antibacterial catcher, wherein, blood flow inlet pipe, the first cavity, blood effuser is communicated with successively, the first power wheel and the second cavity are separately positioned on the both sides of the first cavity, between the first cavity and the second cavity, by isolating membrane, separate, on isolating membrane, offer the through hole that diameter is 1.0-1.7 μ m, one end of the second cavity is connected with one section of extension cavity that is connected to blood effuser, extend cavity and be provided with antibacterial catcher, antibacterial catcher outlet aperture is 0.10-0.32 μ m, the second power wheel is arranged on and extends cavity one side, the port of export of the entrance point of blood flow inlet pipe and blood effuser is all provided with syringe needle.The first power wheel and the second power wheel can adopt eccentric or on wheel week, projection be set.
As preferably, described in extend cavity and comprise junctional membrane, the two ends of junctional membrane connect respectively the outer wall of the second cavity and the outer wall of blood flow inlet pipe, wherein junctional membrane laminating is fixed on the outer wall of blood flow inlet pipe, antibacterial catcher is fixed on junctional membrane.
As preferably, on described isolating membrane, offer the through hole that diameter is 1.5 μ m, antibacterial catcher outlet aperture is for being 0.22 μ m.
The present invention compared with prior art, has the following advantages and effect: simple in structure, low cost of manufacture, reduced patient's cost of use, and blood can be back to human body, has reduced the loss of blood.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
Referring to Fig. 1, the present embodiment blood antibacterial gathering-device, comprise blood flow inlet pipe 1, blood effuser 2, the first cavity 3, the first power wheel 4, the second cavity 5, the second power wheel 6, antibacterial catcher 7, wherein, blood flow inlet pipe 1, the first cavity 3, blood effuser 2 is communicated with successively, the first power wheel 4 and the second cavity 5 are separately positioned on the both sides of the first cavity 3, between the first cavity 3 and the second cavity 5, by isolating membrane 8, separate, on isolating membrane 8, offer the through hole that diameter is 1.5 μ m, one end of the second cavity 5 is connected with one section of extension cavity 9 that is connected to blood effuser 2, extend cavity and be provided with antibacterial catcher 7, antibacterial catcher 7 outlet apertures are 0.22 μ m, the second power wheel 6 is arranged on and extends cavity 9 one sides, the port of export of the entrance point of blood flow inlet pipe 1 and blood effuser 2 is all provided with syringe needle 10.Extend cavity 9 and comprise junctional membrane 91, the two ends of junctional membrane 91 connect respectively the outer wall of the second cavity 5 and the outer wall of blood flow inlet pipe 2, and wherein junctional membrane 91 laminatings are fixed on the outer wall of blood flow inlet pipe 2, and antibacterial catcher 7 is fixed on junctional membrane 91.
The use procedure of the present embodiment is as follows:
Syringe needle 10 on blood flow inlet pipe 1 inserts human vein blood vessel, syringe needle 10 on blood effuser 2 turns back to human vein blood vessel, under the first power wheel 4 effects, blood enters the first cavity 3 along blood flow inlet pipe 1, in the first power wheel 4 rotation processes, the first power wheel 4 applies the pressure to the first cavity 3, thereby make the blood in the first cavity 3 produce outside pressure to isolating membrane 10, the composition that in blood, diameter is less than 1.5 μ m (is mainly antibacterial, blood plasma) can enter the second cavity 5, the interior liquid of the second cavity 5 enters and extends cavity 9, the material that wherein diameter is less than 0.22 μ m enters blood effuser 2 (being mainly plasma fraction) by the outlet of antibacterial catcher 7, wherein diameter is that composition (being mainly antibacterial) between 0.22 μ m-1.5 μ m has been enriched in antibacterial catcher 7, take out antibacterial catcher 7, can the subsequent operation such as cultivate to the antibacterial of enrichment.
Above content described in this description is only made for the present invention illustrating.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of description of the present invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
