Description
Technical field
The present invention relates to armarium, especially laboratory and Hospital Pathological Department analysis center gathers the harvester of the liquid such as urine, is specially a kind of disposable airtight body fluid indwelling device.
Background technology
Urinalysis result provides information for judging the disease of interior internal organs pipe in advance and for judging current health status of testee etc..So each hospital and test center all carry out urine test as the personnel to substantial amounts of new patient, checked UP routinely, inpatient and other person of needs.
Generally, quizzee need to go one dixie cup of use in toilet to collect its urine sample, dixie cup is put on a shelf specified of laboratory the most again or urine is being poured in the test tube specified.Urine sample is after laboratory or other place have been collected, and urine sample is sent in another laboratory carry out urinalysis.
The analysis method of traditional A urine sample collection device has many defects.As some testee is difficult to be discharged in urine cup urine, he (she) often can be in one's hands for urine or clothes, and this acquisition mode has the defect in terms of health.Further, since easily overturn dixie cup and during dixie cup is delivered to appointed place when soaking reagent paper, urine is easy to spill from dixie cup, and testee needs to be very careful when processing urine sample.
Under many circumstances, substantial amounts of urine sample need to be tested complete in one day, and when the wide-mouth dixie cup that these are put one by one account for sizable place to such an extent as to needs the biggest one piece of area to deposit them until chemically examining.And when room is tested in they feeding rooms, it is possible to cause scattering and disappearing of urine sample in dixie cup because accidentally dropping or tilt.The environment so this situation not only can have been made dirty, and some urine samples may be caused not use in chemical examination again.The urine sample that additionally a lot of testees collect is much more a lot of than being actually needed, therefore when the urine sample of a large amount of tested persons puts together, they give out a pungent smell, and big havoc and reduce doctor, nurse and other make the work efficiency of personnel of urine analysis.
And the structure of prior art is complicated, gathers liquid the longest, adopt liquid complex steps, and still have urine to spill phenomenon leakage.Such as Chinese Patent No. 201120203292.0, employ urine cup, switch base, test tube, 4 parts compositions of connecting tube;During gathering liquid, need 6 steps: assembling, for the first time rotating switch seat make urine cup obstructed with test tube, then gathering urine, again rotating switch seat makes urine flow into test tube, urine enters after test tube 4 rotating switch seat closed test tube again, separating urine cup, wherein 3 operations of rotating switch are sufficiently complex;Adopting liquid time cumulation with 50 person-times to average note, it is 31s that No. 201120203292.0 patent gathers the urine time, and has and dissipate leakage.
Therefore, how by urine sample rapid and convenient and the safety of collection without putting into the container specified with spattering leakage, and design simple in construction, processing is simple, and operation is few, it is simple to the product of operation, becomes the technical problem that industry is urgently to be resolved hurrily.
Summary of the invention
One of goal of the invention of the present invention is, disclose a kind of by urine sample rapid and convenient and safety without injecting the test tube specified with spattering leakage, test tube outer wall is difficult to touch urine and is difficult to by urine pollution, during perfusion urine, drain urine that is smooth and easy and that be poured in test tube is difficult to outflow when outwelling unnecessary urine, design simple in construction, easy making process, easy to operate health, avoid cross-contamination, meet the disposable airtight body fluid indwelling device of Laboratory biosafety requirement.

The present invention has a following major advantage:
1、
The body fluid indwelling device of the present invention has can be by urine sample rapid and convenient and safety without injecting the test tube specified with spattering leakage, test tube outer wall is difficult to touch urine in the process, it is difficult to by urine pollution, outflow all it is difficult to when tilting liquid-discharging means of bottle and outwelling unnecessary urine and after separating liquid-discharging means of bottle irrigating the urine that is smooth and easy and that be poured in test tube of drain during urine, design simple in construction, easy making process, easy to operate health, avoid cross-contamination, meet the disposable airtight body fluid indwelling device of Laboratory biosafety requirement.
2、
Test tube assembly in the present invention, the upper surface of the described movable part of test tube plug is arranged over having guide effect when detection device (such as strip etc.) is inserted by axial depression, the end alignment depression of detection device, without the through hole being directed on test tube plug, only need to be achieved that and insert easily by user.
3、
The depression of the test tube plug in the present invention reduces resistance when detection device inserts so that detection device is easier to insert from test tube plug.
4、
Owing to there being movable part upper surface to enclose the depression of formation, when detection device takes out from the through hole of test tube plug, it is difficult to the taking out of outside test tube assembly of liquid in test tube;When depression is enclosed when being formed by medial wall and the movable part upper surface of the body first of passage, owing to passage has certain height, can more effectively avoid detecting liquid that device takes out of in test tube when taking out from the through hole of test tube plug to outside test tube assembly, thus reduce pollution.
5、
After being inoculated with liquid in test tube, when tilting test tube, the movable part of liquid extruding test tube plug, the depression of test tube plug can stop movable part to deform effectively, thus realizes the closure to liquid.
6、
The present invention is in application process, test tube assembly and liquid-discharging means of bottle coordinate fixing for a long time, just liquid-discharging means of bottle is removed after test tube irrigates liquid, the test tube plug of prior art is difficult to recover owing to being chronically at deformation state, and the circular arc that the test tube plug of the present invention produces owing to being provided with depression and easily recovery structure can make the movable part of test tube plug recover in time, thus realize the closure to liquid.
7、
When the bottom of liquid-discharging means of bottle coordinates with test tube plug, the projection on test tube plug and the fit depressions on liquid-discharging means of bottle bottom, there is preferable sealing effectiveness;On the other hand, liquid-discharging means of bottle and when coordinating of test tube plug, in the groove of the bottom that the projection on test tube plug is arranged in liquid-discharging means of bottle, can have and play the effect that cooperation carries out positioning, it is possible to increase the firmness coordinated.
8、
Depression due to test tube plug so that the lateral wall of liquid-discharging means of bottle bottom can coordinate with test tube plug passage medial wall to fix and coordinate the most easily stablizes difficult drop-off.
