Description
Technical field
The present invention relates to a kind of medical apparatus, particularly a kind of blood antibacterial collection device.
Background technology
Existing clinical treatment field, to the patient suspecting that antibacterial infects, often repeatedly to cultivate, generally to increase positive rate
Needing to gather 2-3 set hemoculture (blood sampling volume is generally at more than 60ml), this is for Anemic patients or child, is one
Heavy body burden.And the hemoculture expense eighteenth of the twenty is expensive, this also brings the biggest economic pressures to patient, the most how to close
Antibacterial in reason, economically enrichment patient blood is current this area institute problem demanding prompt solution.
Summary of the invention
The blood loss existed is big, the problem of both expensive to it is an object of the invention to overcome blood antibacterial in prior art to collect,
And a kind of reasonable in design is provided, the blood antibacterial collection device that blood loss is few, cost of use is low.
The present invention solves the problems referred to above and be the technical scheme is that
A kind of blood antibacterial collection device, it is characterised in that: include blood flow to pipe, blood effuser, the first cavity, the
One power wheel, the second cavity, the second power wheel, antibacterial catcher, wherein, blood flows to pipe, the first cavity, blood stream
Going out pipe to be sequentially communicated, the first power wheel and the second cavity are separately positioned on the both sides of the first cavity, the first cavity and the second cavity
Between separated by isolating membrane, isolating membrane offers the through hole of a diameter of 1.0-1.7 μm, one end of the second cavity connects to be had
One section of extending cavity being connected to blood effuser, extending cavity is provided with antibacterial catcher, and antibacterial catcher outlet aperture is
0.10-0.32 μm, the second power wheel is arranged on and prolongs extending cavity side, and blood flows to entrance point and the blood effuser of pipe
The port of export be mounted on syringe needle.First power wheel and the second power wheel can use eccentric or arrange projection on wheel week.
As preferably, described in prolong extending cavity and include junctional membrane, the two ends of junctional membrane connect respectively the second cavity outer wall and
Blood flows to the outer wall of pipe, and wherein junctional membrane laminating is fixed on blood and flows on the outer wall of pipe, and antibacterial catcher is fixed on connection
On film.
As preferably, described isolating membrane offering the through hole of a diameter of 1.5 μm, antibacterial catcher outlet aperture is for for 0.22
μm。
The present invention compared with prior art, has the following advantages and effect: simple in construction, low cost of manufacture, decreases patient
Cost of use, blood can be back to human body, decreases the loss of blood.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following example are to the present invention
Explain and the invention is not limited in following example.
See Fig. 1, the present embodiment blood antibacterial collection device, flow to pipe 1, blood effuser the 2, first cavity including blood
3, first power wheel the 4, second cavity the 5, second power wheel 6, antibacterial catcher 7, wherein, blood flows to pipe 1, first
Cavity 3, blood effuser 2 are sequentially communicated, and the first power wheel 4 and the second cavity 5 are separately positioned on the both sides of the first cavity 3,
Separated by isolating membrane 8 between first cavity 3 and the second cavity 5, isolating membrane 8 offer the through hole of a diameter of 1.5 μm,
One end of second cavity 5 connects one section of extending cavity being connected to blood effuser 29, and extending cavity is provided with antibacterial and collects
Device 7, antibacterial catcher 7 outlet aperture is 0.22 μm, and the second power wheel 6 is arranged on and prolongs extending cavity 9 side, blood stream
The entrance point of inlet pipe 1 and the port of export of blood effuser 2 are mounted on syringe needle 10.Prolong extending cavity 9 and include junctional membrane 91,
The two ends of junctional membrane 91 connect the outer wall of the second cavity 5 respectively and blood flows to the outer wall of pipe 2, and wherein junctional membrane 91 pastes
Conjunction is fixed on blood and flows on the outer wall of pipe 2, and antibacterial catcher 7 is fixed on junctional membrane 91.
The use process of the present embodiment is as follows:
Blood flows to the syringe needle 10 on pipe 1 and inserts human vein blood vessel, and it is quiet that the syringe needle 10 on blood effuser 2 turns back to human body
Arteries and veins blood vessel, under the first power wheel 4 effect, blood flows to pipe 1 along blood and enters the first cavity 3, the first power wheel 4 turns
During Dong, the first power wheel 4 applies the pressure to the first cavity 3, so that the blood in the first cavity 3 is to isolation
Film 10 produces outside pressure, and in blood, diameter can enter second less than the composition (predominantly antibacterial, blood plasma) of 1.5 μm
Cavity 5, in the second cavity 5, liquid enters extending cavity 9, and wherein diameter passes through antibacterial catcher less than the material of 0.22 μm
The outlet of 7 enters blood effuser 2 (predominantly plasma fraction), and the composition between the most a diameter of 0.22 μm-1.5 μm is (main
Antibacterial to be) it is enriched in antibacterial catcher 7, take out antibacterial catcher 7, after the antibacterial of enrichment can being carried out cultivation etc.
Continuous operation.
Above content described in this specification is only illustration made for the present invention.The technical field of the invention
Technical staff described specific embodiment can be made various amendment or supplement or use similar mode to substitute,
Without departing from the content of description of the invention or surmount scope defined in the claims, all should belong to the present invention's
Protection domain.
