The second tube connector is used for connecting two adjacent sample storage units, and can be according to the need of Samples detectionWant, select the amount of imbitition sample, in the time that required liquid sample amount is less, the second tube connector can be insertedLower position in sample storage unit; Certainly, the 3rd tube connector is also similarly can adjust it at specimen bottleIn position; The number of the number of the second tube connector and sample storage unit can be adjusted as requiredWhole;
Shape, the big or small phase of the second projection, the 3rd convex shape, size and the interior latch of lockhole of specimen bottle capAdaptive, projection has formed check configuration with the latch in lockhole, has ensured the fastness, the sealing that connectProperty, prevent the outflow of specimen fluids.
Liquid sample collector of the present invention, is particularly useful for many bottles of samples of disposable collection and does not need one bottleOne bottle of collection, significantly improves collecting efficiency and accuracy, prevents the sample contamination that multi collect brings.
As preferred technical scheme: described the first connecting portion is frustum. The first connecting portion of frustum,Can guarantee that the first tube connector is combined more closely with hard attractor or piercing needle, prevent from coming off.
As preferred technical scheme: described the second connecting portion is frustum. The second connecting portion of frustum,Can guarantee that the 3rd tube connector is combined more closely with negative pressure suction device, prevent from coming off.
As preferred technical scheme: be provided with scale on described body. Can handled easily personnel accurately slapHold the amount of gathered liquid sample.
As preferred technical scheme: described lockable mechanism is clip. Employing clip structure is simple, cost is lowHonest and clean and easy operating.
As preferred technical scheme: be also provided with the second bottle cap for airtight described specimen bottle. Second bottleLid, for complete lid, does not arrange lockhole, completes, linkage unit is all moved for liquid sample collectionAfter removing, sealing specimen bottle, then send clinical laboratory's inspection, thereby can further prevent that liquid sample from polluting.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: liquid of the present inventionSample body collector, can be so that gather multitube (bottle) sample simultaneously, simplified existing operating procedure,Shorten the operating time, reduce and pollute simultaneously, effectively prevent that medical personnel from infecting.
