Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

as shown in figures 1 to 5, the test cup for the thromboelastogram test comprises a cup body 1 and a swing rod 2, wherein the swing rod 2 is of a V-shaped structure formed by a stress rod 22 and a test rod 21, the test rod 21 extends into the cup body 1, the stress rod 22 is positioned outside the cup body 1, the cup body 1 is provided with a supporting structure, an inner groove 23 in the top end of the swing rod V-shaped structure is connected with the supporting structure of the cup body 1 through line contact, and the swing rod 2 can swing relative to the cup body 1.

The test rod 21 is positioned in the cup body 1 and is immersed in a blood sample, the stress rod 22 is positioned outside the cup body 1, and during detection, a detection unit component of the detection instrument is connected with the stress rod 22 to drive the swing rod 2 to swing, and the viscosity and the elastic change of the blood sample are obtained by detecting the moment change generated when the swing rod 2 acts. The connection structure of the inner groove 23 at the top end of the V-shaped structure of the swing rod and the cup body 1 has a very small contact area, so that the swing rod can swing approximately without resistance, the influence of interference resistance is avoided when the viscosity and the elasticity of a blood sample are tested, and more accurate data can be obtained.

Preferably, the top end of the supporting structure of the cup body 1 is acute-angled, the inner groove 23 at the top end of the swing rod V-shaped structure is a square groove, and the top end of the supporting structure of the cup body abuts against one corner of the inner groove 23 at the top end of the swing rod V-shaped structure, as shown in fig. 2 and 3.

Preferably, the front wall 11 of the cup body 1 is provided with a multi-stage inclined surface which is close to the rear wall 12 of the cup body 1, and the supporting structure of the cup body 1 is arranged on the first-stage inclined surface 111 of the front wall of the cup body, as shown in fig. 3. The front cup wall 11 is a multi-stage slope structure, which not only can make the stress rod 22 in a natural vertical downward state at the initial position, but also can narrow the inner cavity at the bottom of the cup body 1, so that the blood sample is more concentrated.

Preferably, the cup walls 13 on the two sides of the cup body 1 are vertically arranged in parallel or are arranged to be narrowed from top to bottom, the rear cup wall 12 of the cup body 1 is arranged to be inclined towards the front cup wall 11, as shown in fig. 3 and 4, the structure can narrow the inner cavity at the bottom of the cup body 1, and blood samples are concentrated.

Preferably, the bottom of the test rod 21 is an L-shaped test head 211, and the test head 211 is completely immersed in the blood sample during use, as shown in fig. 2 and 3. The detection principle of the test cup is that the change of the blood viscosity is analyzed by detecting the resistance moment received by the swing rod 2 in the swing process, blood flows along the wall of the swing rod 2 contacted with the blood, the viscosity is different, and the flowing speed is also different, so that in order to ensure that the blood bears the same fluid resistance in each swing, the test head 211 is made into an L shape, and the fluid can be instantly prevented from flowing along the wall of the swing rod 1.

Preferably, the width of the test head 211 should be as much as possible smaller than the inner cavity of the cup body 1 on the premise of ensuring a sufficient stressed area, so as to ensure that the sample flows smoothly when the swing rod 2 swings, as shown in fig. 4. Because the fluid is an incompressible object, when the swing rod 2 swings, the liquid in the swinging forward direction flows to the rear of the L-shaped test head 211, and the swing rod 2 detects the viscosity change of the liquid, so that in order to avoid the influence of the gravity of the liquid, the liquid flows smoothly, the liquid level is prevented from being increased, and a sufficiently large gap must be ensured between the swing rod 2 and the cup body 1.

Preferably, the lower portion of the force-bearing rod 22 is provided with a transverse square bar 221, and the two side walls 13 of the cup body 1 are narrowed upwards above the square bar 221, so that the two ends of the square bar 211 extend to positions beyond the inner side surfaces of the two side walls 13 of the cup body 1, as shown in fig. 1 and 5. The extension length of the square bar 211 can prevent the swing rod 2 from falling when the cup body 1 is placed at will, and meanwhile, the square bar 221 is convenient for the detection unit assembly of the detection instrument to grab the swing rod 2.

Preferably, the cup body 1 and the swing rod 2 are both formed by injection molding of plastic materials.

In actual detection, in order to improve detection efficiency, often a plurality of test cups ally oneself with the cup and use, the utility model provides a test cup can realize ally oneself with the cup form equally, as shown in fig. 6, utilizes a plurality of test cups to connect the shaping along cup side direction, constitutes to ally oneself with the cup and uses. When the cup body 1 is formed by injection molding, the cup connecting structure is very easy to realize, and only a plastic material with certain thickness needs to be added between the side cup walls of two adjacent test cups.

It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form, and any simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
