Description
Technical field
The utility model relates to one and gathers and pretreated device biological specimen, specifically a kind of biological specimen collection and pretreatment unit.
Background technology
In hospital clinical and medical research test, often need the ight soil to patient, urine, sputum, swab equal samples to gather and carry out necessary pre-treatment (as the increasing bacterium of the digestion of sputum sample, fecal sample, the homogenizing of swab sample).Contriver was in a kind of biological specimen collection pipe being exclusively used in automation bacteria separation and Culture of application in 2008.This patent is having played certain effect for when the collection of sample and separation and Culture, and Biosafety risk when it has evaded sampling, being again a vitals of separation and Culture device simultaneously, serving crucial effect for completing automatization separation and Culture smoothly.But this design also exists again larger drawback.First, stir sputum sample with little magnetic patch, inadequate owing to stirring dynamics, Blending Efficiency of Blending is not good, and part sputum sample is stirred not open; It two easily produces aerosol when being and stirring sputum sample, and due to the original design safeguard procedures not having to respond, operator are easy to the pollution being subject to sample, constitute a serious threat to the healthy of operator.In order to solve the problem, contriver designs the art of this patent, thoroughly to complete the digestive process to sputum sample, and has evaded the problem of the Aerosol Pollution in sputum digestive process.
Utility model content
Technical problem to be solved in the utility model is the defect existed for existing biological specimen collection pipe, a kind of novel biological specimen collection and pretreatment unit are provided, can use with automation bacteria separation and Culture matched with devices, thus complete the automatization separation and Culture of biological specimen.
The technical solution of the utility model is achieved in that it comprises collection tube (1), collection tube (1) is provided with pipe lid (2), groove (12) is provided with in the middle of pipe lid (2), it is characterized in that: collection tube (1) bottom is connected with sample retaining devices (3), top, pipe lid (2) bottom is provided with cover plate (11) and adsorption layer (5), and adsorption layer (5) is for filtering the aerosol stirring sample and produce.Cover plate (11) has ventilating pit (10), pipe lid (2) central authorities are provided with hollow form push rod (4), push rod hollow design, to be convenient to from upper end filling reagent to body; Hollow form push rod (4) is from top to bottom through the bottom of cover plate (11), adsorption layer (5) and pipe lid groove (12), and be connected in pipe lid bottom groove (12) and stretch in the body of collection tube (1), hollow form push rod (4) surrounding going deep into body portion is provided with stirring piece (6), along with the rotation of push rod, stirring piece is for stirring sample; Collection tube (1) and pipe lid (2) seal, sample retaining devices (3) is provided with collection tube room (7) and sample pool (8), the bottom of collection tube room (7) is provided with ailhead shape prominence (9), and collection tube room (7) and sample pool (8) pass through channel connection.Described adsorption layer (5) is sponge block or other filtering material.Described collection tube and sample retaining devices assist to use.Sample retaining devices is made up of collection tube holding chamber and sample pool two portions.The bottom of collection tube holding chamber is provided with ailhead shape prominence, and holding chamber and sample pool are interconnected by passage.After collection tube puts into collection tube holding chamber, first drive push rod to rotate by external force, sample is stirred, after stirring completes, design external force is exerted pressure to collection tube top, and ailhead shape prominence punctures bottom collection tube, liquid sample is flowed out, enters sample pool by passage.And then completed streak inoculation and the separation and Culture process of sample from culture apparatus by automatic partition.
The utility model has following characteristics:
1) biological specimen can directly collect in corresponding collection tube, and safe transport is to Microbiological Lab.Operator, without the need to opening sample collection pipe, can digest sample without the need to contacting sample, increase the pre-treatment such as bacterium, reduce the infected danger of operator.
2) by the upper end of hollow push rod filling enrichment liquid, Digestive system or transmit matrix etc., safety and facilitating.
3) for respiratory tract sample, there will be aerosol digesting it, in whipping process, the sponge block of Guan Gai general headquarters design can be avoided polluting operator.
4) pre-treatment complete after sample enter sample pool by unique mode, middle without the need to any sample branching program, whole process is smooth and fast.
5) saved numerous and diverse manual program, made separation and Culture more at random, more fast and conveniently.

Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises collection tube (1), collection tube (1) is provided with pipe lid (2), groove (12) is provided with in the middle of pipe lid (2), collection tube (1) bottom is connected with sample retaining devices (3), top, pipe lid (2) bottom is provided with cover plate (11) and adsorption layer (5), and adsorption layer (5) is for filtering the aerosol stirring sample and produce.As shown in Figure 3, cover plate (11) has ventilating pit (10), pipe lid (2) central authorities are provided with hollow form push rod (4), push rod hollow design, to be convenient to from upper end filling reagent to body; Hollow form push rod (4) is from top to bottom through the bottom of cover plate (11), adsorption layer (5) and pipe lid groove (12), and be connected in pipe lid bottom groove (12) and stretch in the body of collection tube (1), push rod can be separated with pipe lid by this linking under external force, removes pipe lid to the sealing of body.Hollow form push rod (4) surrounding going deep into body portion is provided with stirring piece (6), and push rod 4 can depart from pipe lid and rotates under external force drives, when it rotates with stirring piece 6 by sample stirring and evenly mixing.Described adsorption layer (5) is sponge block.Collection tube (1) and pipe lid (2) seal, sample retaining devices (3) is provided with collection tube room (7) and sample pool (8), the bottom of collection tube room (7) is provided with ailhead shape prominence (9), and collection tube room (7) and sample pool (8) pass through channel connection.Described collection tube and sample retaining devices assist to use.Sample retaining devices is made up of collection tube holding chamber and sample pool two portions.The bottom of collection tube holding chamber is provided with ailhead shape prominence, and holding chamber and sample pool are interconnected by passage.After collection tube puts into collection tube holding chamber, first drive push rod to rotate by external force, sample is stirred, after stirring completes, design external force is exerted pressure to collection tube top, and ailhead shape prominence punctures bottom collection tube, liquid sample is flowed out, enters sample pool by passage.And then completed streak inoculation and the separation and Culture process of sample from culture apparatus by automatic partition.
