Detailed Description

The invention will be further explained with reference to the following figures and examples:

example 1, as shown in fig. 1-3, the utility model comprises an outer test tube 1, a connecting cap 6 disposed on the upper end of the outer test tube 1, a jack 9 disposed on the center of the top surface of the connecting cap 6, threads disposed on the inner surface of the side wall of the connecting cap 6 and the outer surface of the side wall of the upper end of the outer test tube 1, an inner test tube 5 passing through the lower portion of the jack 9 and having a conical shape, an extension portion 4 disposed horizontally and outwardly of the opening of the inner test tube 5, the outer diameter of the extension portion 4 being larger than the radial dimension of the jack 9 and smaller than the radial dimension of the connecting cap 6, a fixing cap 7 disposed above the connecting cap 6, the connecting cap 6 being larger than the fixing cap 7 in height, the top surface of the fixing cap 7 being a puncture pad 8, the puncture pad 8 being made of rubber or silica gel, an annular supporting plate 2 disposed below the puncture pad 8, the supporting plate 2 and the axis of the connecting cap 6, the outer surface of the side wall of the connecting cap 6 and the inner surface of the side wall of the fixing cover 7 are both provided with threads, the connecting cap 6 is in threaded connection with the fixing cover 7, and the lower surface of the bearing plate 2 is provided with a sealing gasket.

In this embodiment, in consideration of the necessity of using the inner tube 5 (small tube), the inner tube 5 (small tube) is placed inside the outer tube 1 (large tube), and then a label marked with detailed information of the patient is pasted on the tube body of the outer tube 1, the upper end of the inner tube 5 is lapped on the upper surface of the connection cap 6, and no matter what size of the inner tube 5 is replaced, it is ensured that the extension portion 4 at the upper end of the inner tube 5 intersects with the connection cap 6 in the horizontal direction.

The utility model discloses there are two kinds of application methods:

1. after the test tube 5 in blood sample gathered, the anticoagulant ethylene diamine tetraacetic acid dipotassium is equipped with in advance to interior test tube 5 bottom, prevent that blood sample from solidifying, pass interior test tube 5 and connect the jack 9 of cap 6 and make the 4 overlap joints of extension in the upper surface of connecting cap 6, then cover fixed lid 7, fixed lid 7 with connect cap 6 threaded connection, make extension 4 suppression fix between the two above-mentioned, the sealed pad of 2 lower surfaces of bearing board is arranged in the blood in sealed test tube 5, insert interior test tube 5 again in outer test tube 1, will connect cap 6 and outer test tube 1 threaded connection, the probe of detecting instrument inserts from the position of the puncture pad 8 of fixed lid 7 at last and detects.

2. To connect 6 threaded connection of cap on outer test tube 1, after interior test tube 5 was gathered to blood sample, with interior test tube 5 pass the jack 9 of connecting cap 6, then cover fixed lid 7, fixed lid 7 with connect 6 threaded connection of cap, the probe of last detecting instrument inserts from the position of the puncture pad 8 of fixed lid 7 and detects.

There are also two methods of removing the inner tube 5 for the above two methods, the connecting cap 6 is rotated when the inner tube 5 needs to be removed in a sealed state; the fixing cap 7 is rotated when the inner test tube 5 is not removed in a sealed state. The height of the connecting cap 6 is larger than that of the fixed cover 7, so that the connecting cap 6 can be directly controlled conveniently.

Embodiment 2, the utility model discloses an outer test tube 1, set up the connecting cap 6 in the upper end of outer test tube 1, set up jack 9 in the top surface center of connecting cap 6, set up recess 3 in the upper surface of the top surface of connecting cap 6, recess 3 and connecting cap 6 axis collineation, jack 9 is located the bottom surface of recess 3, set up the screw thread in the internal surface of the lateral wall of connecting cap 6 and the surface of the lateral wall of outer test tube 1 upper end, connecting cap 6 and outer test tube 1 threaded connection, still include the lower part that passes jack 9 is conical inner test tube 5, the opening level of inner test tube 5 is equipped with extension 4 outwards, the height of recess 3 is the same with the thickness of extension 4, the width of recess 3 is the same with the width of extension 4, the external diameter of extension 4 is greater than the radial dimension of jack 9 and is less than the radial dimension of connecting cap 6, set up fixed lid 7 above connecting cap 6, connect cap 6 highly be greater than fixed lid 7, the top surface of fixed lid 7 is puncture pad 8, puncture pad 8 is rubber or silica gel material, sets up annular bearing board 2 in puncture pad 8's below, and bearing board 2 all sets up the screw thread with the internal surface of connecting cap 6 lateral wall, at the surface of connecting cap 6 lateral wall and the internal surface of fixed lid 7 lateral wall, connects cap 6 and 7 threaded connection of fixed lid, sets up sealed the pad at the lower surface of bearing board 2.

In this embodiment, in order to guarantee probe male accuracy, it is inaccurate to avoid interior test tube 5 to place the position, consequently, recess 3 has been seted up at the upper surface of connecting cap 6 in this embodiment, extension 4 just can be placed in recess 3, recess 3's height is the same with extension 4 thickness promptly, can not influence the suppression of the extension 4 of fixed lid 7 to interior test tube 5 like this, and recess 3's width is the same with extension 4's width, to the interior test tube 5 of unidimensional, can set up extension 4 unified to the size with recess 3 matched with.
