Abstract
The utility model relates to an anaerobic sample tube for investigation, which is composed of a plug 1, a sample tube 2, a piston 3 with a piston hole 4, a draw rod 6, etc. The sample tube 2 is filled with carbon dioxide gas to be suitable for anaerobe to survive, and the accuracy of the anaerobic culture test can be enhanced.
Description
The utility model belongs to the medical test articles for use, a kind of anaerobism censorship specimen tube.
Do not have anaerobism censorship specimen tube now clinically, generally all use common sterile tube.Its major defect is: 1, censorship at once behind doctor's collect specimen.2, in the sample censorship process, most of anaerobion death.3, a large amount of aerobic bacterias growth earlier in double dish runs out of oxygen and has also consumed nutriment dead the time and changed the pH value of nutrient culture media, is unfavorable for the anaerobion growth.
In order to overcome above-mentioned defective, the purpose of this utility model is that design is a kind of in the censorship process, can make the anaerobion survival for a long time and make the anaerobism censorship specimen tube of aerobic bacteria death.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
The plug 1 of described anaerobism censorship specimen tube covers on specimen tube 2.The bottom center of specimen tube 2 has a hole, and sealing ring 7 is installed on the hole.One minimum piston hole 4 is arranged on the piston 3.After piston 3 passed through heat pressure adhesive with pull bar 6, piston 3 upper surfaces were concave surface, make the tangible material in the sample precipitable in this.The other end of pull bar 6 passes sealing ring 7, is passed by the test tube bottom outlet, is connected with bull drilling and backward pulls 8 by screw thread, and carry out hot pressing to rubber seal ring 7 this moment again, makes it be sealingly fastened in the bottom centre of specimen tube 2.Cutting apart the space of specimen tube 2 by piston 3, is Specimen Room 9 on it, and it is CO down
2Gas compartment.
Owing to adopt as above technical scheme, the utlity model has following superiority:
Anaerobism censorship specimen tube is widely used in various solid, liquid body samples such as urine, excrement, puncture fluid, drainage liquid, slough, phlegm, can keep the anaerobion survival for a long time and make aerobic bacteria death, and can prevent the outside contamination sample, thereby improve the accuracy rate of anaerobic bacteria culture.
Below in conjunction with the description of drawings specific embodiment:
Fig. 1: anaerobism censorship specimen tube one-piece construction synoptic diagram.
As shown in FIG.: the 1-plug; The 2-specimen tube; The 3-piston; The 4-piston hole; 5-CO
2Gas compartment; The 6-pull bar; The 7-sealing ring; The 8-bull drilling and backward pulls; The 9-Specimen Room.
As Fig. 1: plug 1, piston 3 and sealing ring 7 are cast by rubber.Specimen tube 2, pull bar 6, bull drilling and backward pulls 8 are transparent plastic foundry goods.Earlier sealing ring 7 is installed in the hole of specimen tube 2 bottoms.Piston 3 with after pull bar 6 heat pressure adhesives are connected, with the other end of pull bar 6 by the bottoms that pass specimen tube 2 in the specimen tube 2 by sealing ring 7, by the upper connecting rod handle 8 that is threaded, then sealing ring 7 outsides are carried out hot pressing again, make it be sealingly fastened in the bottom centre of specimen tube 2.To combinations thereof part and plug 1 sterilization that carries out disinfection, and in aseptic CO
2In the environment,, discharge gas in the specimen tube 2, suck CO by spurring piston 3 back and forth
2Gas covers plug 1 again, and makes piston 3 rise to the test tube top position, is partitioned into Specimen Room 9 and CO
25 two spaces of gas compartment.
During use, open plug 1, rapidly sample is placed Specimen Room 9, build plug 1.Pulling down piston 3 again inspected by ready samples to 2 ends of specimen tube.Piston 3 can be pulled to pipe when being designated as liquid and needing when centrifugal at the end, outside specimen tube 2, cut off again the 6 neat ends of pull bar centrifugal.
Claims (2)
1, a kind of anaerobism censorship specimen tube is characterized in that: described anaerobism censorship specimen tube is divided into the Specimen Room 9 on top and the CO of bottom by piston 3 with specimen tube 2
2Gas compartment 5.A minimum piston hole 4 is arranged on the piston 3.Piston 3 is with after pull bar 6 heat pressure adhesives are connected, and the upper surface of piston 3 is a downward concave surface.
2, anaerobism is inspected specimen tube by ready samples according to claim 1, it is characterized in that: there is a hole in the bottom centre of described anaerobism censorship specimen tube, rubber seal ring 7 is housed on the hole, after pull bar 6 has been installed in the sealing ring 7, in the outside sealing ring 7 is carried out hot pressing, make it be sealingly fastened in the bottom centre of specimen tube 2.Pull bar 6 links to each other with bull drilling and backward pulls 8 by screw thread.
