Detailed Description
Two embodiments of the present invention are described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to fig. 3, it is a schematic view of a blood collection tube according to a first embodiment of the present invention. The blood collection tube comprises a storage tube 10, a blocking cap 20 arranged on the storage tube 10, and a rubber plug 30 arranged in the blocking cap 20. It is contemplated that there are other devices for labeling blood collection tubes, such as automatic labeling devices, which are well known to those skilled in the art and will not be described in detail herein.
The storage tube 10 is closed at one end and has an opening at the other end. The opening is provided with a step 11 and comprises a first diameter cylinder 111 and a second diameter cylinder 112. The first diameter cylinder 111 has an inner diameter larger than that of the second diameter cylinder 112 to form the step 11. The operation of the stepped portion 11 will be described in detail below with reference to the plugging cap 20.
One end of the plugging cap 20 abuts against the step part 11. The blocking cap 20 is provided with a ring of protrusions 22 at an outer side of an end far away from the storage tube 10, the diameter of the protrusions 22 is smaller than the outer diameter of the first diameter cylinder 111, and the lower surface of the protrusions 22 is far away from the upper surface of the first diameter cylinder 111. The inner and outer diameters of the plugging cap 20 are equal to the inner diameters of the second diameter cylinder 112 and the first diameter cylinder 111, respectively, so that the plugging cap 20 can be plugged more tightly when inserted into the first diameter cylinder 111. Stifled cap 20 can be made by plastics to there are different colour varieties, thereby can distinguish according to the difference of colour more aspect the different effects of heparin tube, and then take required heparin tube when needs convenient and fast more. The top of the plugging cap 20 is provided with a through hole 21. The through hole 21 may be circular, and the diameter of the through hole 21 is smaller than the inner diameter of the first diameter cylinder 111.
The plug 30 can be made of rubber, so that the blood collection tube can be sealed well. The outer diameter of the rubber plug 30 is equal to the inner diameter of the plugging cap 20, so that the rubber plug 30 is not loosened when being inserted into the plugging cap 20. And the length of the rubber plug 30 is greater than that of the blocking cap 20, so that a long portion of the rubber plug 30 is inserted into the second diameter cylinder 112 after the blocking cap 20 is inserted. The plug 30 is in interference fit with the second diameter cylinder 112, so that the storage tube 10, the blanking cap 20 and the plug 30 are firmly fixed together. The rubber plug 30 is provided with a cross-shaped cut 31, and the cross-shaped cut 31 penetrates through the rubber plug 30. The cutting direction of the cross cut 31 coincides with the axial direction of the through hole 21. The upper surface and the lower surface of the rubber plug 30 are respectively provided with a groove 32, and the diameter of the opening of the groove 32 is equal to that of the through hole 21. Thus, when taking out the liquid from the blood collection tube, the needle can pass through the through hole 21 and then be inserted into the cross-shaped notch 31 to suck the blood, so that the plug 30 is too thick or too hard to be inserted into the blood collection tube, and the plug cap 20 and the plug 30 do not need to be pulled out, therefore, the plug cap 20 and the plug 30 are not inserted into the storage tube 10, and the subsequent use of the blood collection tube is not influenced.
Compared with the prior art, the utility model provides a blood sampling tube includes a storage tube 10, and a setting is in the stifled cap 20 of storage tube 10, and a setting is in plug 30 in the stifled cap 20. The storage tube 10 has an opening at one end thereof, the opening is provided with a step 11 and includes a first diameter cylinder 111 and a second diameter cylinder 112, and the first diameter cylinder 111 has an inner diameter larger than that of the second diameter cylinder 112 to form the step 11. The blocking cap 20 is provided with a ring of protrusions 22 at an outer side of an end far away from the storage tube 10, the diameter of the protrusions 22 is smaller than the outer diameter of the first diameter cylinder 111, and the lower surface of the protrusions 22 is far away from the upper surface of the first diameter cylinder 111. Because partly of stifled cap 20 and plug 30 all immerses in the storage tube 10 the inside, when labelling, automatic labelling device's only can directly press from both sides tight storage tube 10, and can not contact stifled cap 20, consequently when labelling stifled cap 20 just can not drop and cause the unable bad consequence of posting of label, also consequently can not cause the inefficacy of this blood sampling pipe simultaneously the needle can directly insert from cross incision 31 and draw blood, need not to extract stifled cap 20 with plug 30, also can pinch bulge 22 with stifled cap 20 with plug 30 extracts storage tube 10, consequently stifled cap 20 and plug 30 insert and establish the subsequent use of this blood sampling pipe also can not influenced in the storage tube 10 the inside.
Fig. 4 is a schematic sectional view of a blood collection tube according to a second embodiment of the present invention. The blood collection tube comprises a storage tube 40, a blocking cap 50 arranged on the storage tube 40, and a rubber plug 60 arranged in the blocking cap 50. The only difference between the second embodiment and the first embodiment is the capacity of the storage tube 40. The storage tube 40 includes a step portion 41 provided at an opening end, a storage portion 42 connected to the step portion 41, and a clamping portion 43 covering an outer side of the storage portion 42. The step portion 41 is the same as the step portion 11 of the first embodiment, and is not described in detail here. The reservoir 42 is used for storing blood, and the present embodiment differs from the first embodiment only in that the volume is smaller than that of the first embodiment to accommodate different needs. It is contemplated that the capacity of the reservoir 42 may be designed as desired, i.e., different capacities of the reservoir 42 may be designed as desired for different applications. The capacity of the storage portion 42 in this embodiment is one third of the capacity of the storage tube 10 in the first embodiment.
The overall length of the clamping portion 43 is the same as the axial length of the storage tube 10 of the first embodiment, so that clamping of the automatic labeling device is facilitated without replacing the automatic labeling device due to the reduction of the storage portion 42, and thus not only cost reduction but also efficiency improvement can be achieved.
In this embodiment, the plugging cap 50 and the rubber plug 60 are respectively the same as the plugging cap 20 and the rubber plug 30 in the first embodiment, and detailed description thereof is omitted.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
