As a preferable mode of the present invention, when the test paper cassette is inserted into the insertion slot, the tip end of the blood glucose test paper is positioned in the working channel 2.
In the specific implementation process, taking the middle finger as an example, when a user collects a blood sample, the user inserts the prepared blood glucose test paper into the test paper slot, inserts the test paper box into the insertion slot, and further inserts the middle finger into the bent channel, at this time, the upper knuckle of the middle finger extends into the oblique channel 4, the middle knuckle is in the parallel channel 3, and the middle knuckle in the parallel channel 3 is fixed by the fixing ring 5, so that blood collection can be started.
The user presses the tail end of the pressing shaft with a thumb to arrange the pressing sheet, and for the pressing shaft, the base shaft 13 is the rear section part of the pressing shaft, the outer wrapping shaft 14 is the middle section part of the pressing shaft, and the fixed shaft 15 is the front section part of the pressing shaft, so that the pressing sheet is equivalently arranged at the bottom end of the base shaft 13, and the base shaft 13 drives the outer wrapping shaft 14 and the fixed shaft 15 to move towards the inside of the working channel 2. In the initial state, spring 8 is under normal condition, not influenced by external force, and when the user extruded the pressing piece, base plate 6 was impeld inwards, and under base plate 6 and first limiting plate 7's effect, spring 8 contracts to obtain certain elastic potential energy, have the trend of restoreing.
Because the outer ring of the outer wrapping shaft 14 is set to be in a gear shape, the upper end and the lower end of each gear tooth of the outer wrapping shaft 14 are set to be inclined planes, the directions of the inclined planes at the upper end and the lower end of the gear tooth of the outer wrapping shaft 14 are opposite to the rotating direction of the outer wrapping shaft 14, the first opening 10 and the second opening 12 are set to be in the gear shape, the upper end of the gear tooth of the first opening 10 is provided with an inclined plane, the lower end of the gear tooth of the second opening 12 is provided with an inclined plane, the direction of the inclined plane at the upper end of the gear tooth of the first opening 10 is consistent with the rotating direction of the outer wrapping shaft 14, the inclined plane at the lower end of the gear tooth of the second opening 12 is consistent with the rotating direction of the outer wrapping shaft 14, in the rising process of the outer wrapping shaft 14, the outer wrapping shaft 14 is separated from the gear-shaped first opening 10, the inclined plane at the upper end of the gear tooth of the outer wrapping shaft 14 can contact with the inclined plane at the lower end of the gear tooth of the second opening 12, so as to generate a shifting force, so that the rotator 17 arranged in the outer wrapping shaft 14 continues to rotate, thereby driving the outer wrapping shaft 14 to drive the fixed shaft 15 to rotate. Furthermore, when the user receives force, the spring 8 is restored under the action of elastic potential energy, so that the base shaft 13 is driven to move towards the outer side of the working channel 2, the base shaft 13 drives the outer wrapping shaft 14 to move towards the outer side, the outer wrapping shaft 14 drives the fixed shaft 15 to move towards the outer side, the outer wrapping shaft 14 is separated from the second opening 12 in the moving process, so that the inclined surface of the lower end of the gear tooth of the outer wrapping shaft 14 is contacted with the inclined surface of the upper end of the gear tooth of the first opening 10, a deviation force is generated, and the rotator 17 arranged in the outer wrapping shaft 14 is forced to rotate when the outer wrapping shaft 14 continues to move downwards, so that the outer wrapping shaft 14 is driven to rotate, and the outer wrapping shaft 14 drives the fixed shaft 15 to rotate; repeated movement for many times, so that the outer wrapping shaft 14 can rotate for 360 degrees; the needle 9 is arranged at the bisector of any radius on the upper end surface of the fixed shaft 15, so that the needle 9 is driven to rotate around the center of the fixed shaft 15 during the rotation of the fixed shaft 15.
It should be mentioned that the overall length of the outer covering shaft 14 is smaller than the distance between the first limiting plate 7 and the second limiting plate 11, and because the outer covering shaft 14 is not limited by the first limiting plate 7 and the second limiting plate 11 with the staggered teeth, in the initial state, the outer covering shaft 14 is located in the first opening 10 and does not contact the second opening 12; the inclined surfaces are in contact in such a way that the resolved force components are all in the clockwise or counterclockwise direction, so that the outer bag shaft 14 rotates in the same direction of rotation regardless of the upward or downward movement.
After the needle prick procedure, the user may direct a force so that the upper knuckle squeezes the channel bottom of the diagonal channel 4, thereby squeezing out blood. Because the channel wall of the oblique channel 4 is a frosted surface, when a user extends a finger into the oblique channel 4, a certain friction force can be increased through the frosted surface, so that the skin of the user is tightened, and the needle stick is convenient.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
