The content of the invention
Based on above mentioned problem, the utility model purpose is to provide one kind without manually carry test tube, and transporting velocity is fast, knot
The simple test tube conveying device of structure.
For problem above, there is provided following technical scheme：A kind of test tube conveying device, including both ends are to logical delivery pipe
Body, outer wall of the delivery pipe body wherein one end close to its end are provided with the negative pressure connector being connected with air extractor, institute
Negative pressure connector is stated to communicate with delivery pipe body inner chamber；The end face that the delivery pipe body is provided with negative pressure connector one end is provided with and can turned over
The sealing opened is turned on to renovate；The delivery pipe body internal diameter is more than test tube diameter 1mm to 2mm.
In said structure, by setting negative pressure connector on the outer wall of delivery pipe body one end, using air extractor to negative pressure
Connector is evacuated, and one end end face that negative pressure connector is provided with due to delivery pipe body is renovated provided with sealing, therefore can cause gas
Stream enters delivery pipe body from delivery pipe body relative to one end of negative pressure connector, therefore test tube is filled in into delivery pipe body at blood drawing
When, test tube can follow the side movement that air-flow is renovated towards sealing, and open sealing using self inertia top and renovate, and from delivery pipe body
Inside drop out, delivery pipe body internal diameter has big difference with test tube diameter, transfer efficiency can be caused to be deteriorated, and can not form good suction
Power, such as diameter difference is too small between the two, can increase the transporting resistance of test tube or even clamping stagnation occurs.
The utility model is further arranged to, and the pin joint renovated that seals is located on the outer wall of delivery pipe body, described
It is parallel with the phase tangent line of delivery pipe body outer cylindrical wall to seal the upset axis renovated.
The utility model is further arranged to, and be provided with the pin joint that the sealing is renovated makes to beat for controlling sealing to renovate
Open the torsion spring that its rear reset covers delivery pipe body end face.
In said structure, torsion spring can ensure that test tube top opens to automatically control sealing after sealing is renovated and renovate and cover back delivery pipe again
Body end portion, one end that delivery pipe body is renovated relative to sealing is set to re-form suction force.
The utility model is further arranged to, and flow control valve is provided with the negative pressure connector.
In said structure, flow control valve is used for the suction flow for controlling air extractor, so as to control the mobile speed of test tube
Degree.
The beneficial effects of the utility model：Test tube to be transported by negative-pressure ward, travelling speed is fast, simple in construction,
The connecting at blood drawing and between chemical examination is improved, reduces the working strength of employee, improves operating efficiency.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
With reference to figure 1 and Fig. 2, a kind of test tube conveying device as shown in Figures 1 and 2, including both ends are to logical delivery pipe body
10, the delivery pipe body 10 wherein outer wall of the one end close to its end is provided with and air extractor（Not shown in figure）Connected
Negative pressure connector 11, the negative pressure connector 11 communicate with the inner chamber of delivery pipe body 10；The delivery pipe body 10 connects provided with negative pressure
The end face of 11 one end of mouth is provided with the turnable sealing opened and renovates 12；The internal diameter of delivery pipe body 10 is more than test tube a diameters 1mm
To 2mm.
In said structure, by setting negative pressure connector 11 on one end outer wall of delivery pipe body 10, air extractor pair is utilized
Negative pressure connector 11 is evacuated, and one end end face that negative pressure connector 11 is provided with due to delivery pipe body 10 renovates 12 provided with sealing,
Therefore air-flow can be caused to enter delivery pipe body 10 relative to one end of negative pressure connector 11 from delivery pipe body 10, therefore at blood drawing
When test tube a is filled in into delivery pipe body 10, test tube a can follow air-flow to renovate 12 side movement towards sealing, and utilize self inertia
Top opens sealing and renovates 12, and is dropped out out of delivery pipe body 10, and the internal diameter of delivery pipe body 10 has big difference with test tube a diameters, can cause
Transfer efficiency is deteriorated, and can not form good suction force, and such as diameter difference is too small between the two, can increase test tube a conveying resistance
