accompanying the left movement of the piston plate I13 in fig. 4, when the piston plate I passes through the piston cylinder I7, due to the arrangement of the arc-shaped expansion part on the piston cylinder I7, one side, close to the arc-shaped expansion part on the piston cylinder I7, of the piston plate I13 is difficult to contact with the inner wall and further contact with blood, in the continuous left movement process, one side, adhered with the blood, of the piston plate I13 is made to contact with the opposite side, provided with the test paper belt 11 and the piston plate I13, so that the residual blood on the piston plate I13 is adsorbed, and in particular, a groove can be arranged on the side, on the piston plate I13, of the piston plate I13 for storing more blood.
The slide bar 18 is indirectly limited and supported through the first support plate 5 and the second support plate 6; the blood is extracted and the blood sugar content is measured by the matching use of a piston cylinder I7, a piston cylinder II 8, a bracket 9, a discharging roller 10, a test paper tape 11, a piston rod I12, a piston plate I13, a connecting rod I14, a connecting rod II 15 and a glucometer probe 16; referring to fig. 5, when the first connecting rod 14 is pressed down by the pressing arm 201 in the vertical direction, the second connecting rod 15 is rotated and matched to move the glucometer probe 16 toward the test strip 11, when the glucometer probe 16 touches the test strip 11 after blood absorption, the current blood sugar content of the user can be measured, and the two limiting blocks 161 can limit the motion track of the glucometer probe 16, so that the glucometer probe 16 can only move horizontally and stably.
The rotating disc 17 synchronously rotates along with the rotation of the first shaft 4, in fig. 6, the bottom of the slide block 22 close to the left side is in sliding connection with the inner wall of the spiral groove 21, and the slide block 22 drives the rotating arm 20, the slide bar 18, the triangular block 23, the n-shaped frame 24, the lifting rod 25, the connecting block 26, the first pressure spring 27 and the like to integrally move leftwards under the guidance of the track of the rotating spiral groove 21; once the sliding block 22 contacts with the lifting auxiliary groove 211, the sliding block 22 is lifted up under the influence of the lifting auxiliary groove 211, so that the rotating arm 20 integrally rotates clockwise in the movable through groove 19, the triangular block 23 on the rotating arm 20 rotates clockwise with the step, and the triangular block 23, in the rotating process, can shift the locking block 28, the connecting block 26 and the lifting rod 25 to move upwards after overcoming the elastic force of the first compression spring 27; the other side of the rotated triangular block 23 is contacted with the bottom of the locking block 28 and is acted by the elastic force of the first compression spring 27, so that the angle of the rotated triangular block 23 and the rotating arm 20 is kept unchanged;
when the rotating arm 20 rotates, the slider 22 on the right side contacts the inner wall of the spiral groove 21 and the movable through groove 19 moves to the right integrally under the guidance of the track on the spiral groove 21.
In conclusion, the slide bar 18 can move left and right stably along with the continuous rotation of the first shaft 4 and the rotary table 17;
refer to fig. 6 and 4.
The first piston rod 12 can only perform limited sliding in the second piston cylinder 8, the motion track of the first piston rod 12 is limited, and the slide bar 18 fixedly connected with the first piston rod 12 is synchronously limited in motion track and can only perform limited sliding left and right.
The clockwise rotation of the rotating arm 20 causes the pressing arm 201 thereon to slap the top of the first connecting rod 14, so that the blood glucose meter probe 16 can make contact with the test strip 11 after adsorbing blood.
Refer to fig. 6 and 7.
The shaft pair 30, the one-way bearing 31, the transmission gear 32, the recovery roller 33 and the like are supported through the first support plate 5.
When the slide bar 18 moves left and right, the second shaft 30 is engaged with the one-way bearing 31 to wind the test strip 11 in one direction, so that the test strip 11 after blood absorption can be wound and stored after being measured. In practice, an ultraviolet lamp may be provided in the housing 2, and the used strip 11 may be sterilized by the lamp.
Refer to fig. 8.
By establishing connection between the piston cylinder three 35 in the liquid supply device and the liquid outlet of the insulin pump body 1, insulin supplied by the insulin pump body 1 is temporarily stored in the space on the left side of the piston cylinder three 35, when the piston plate two 37 in fig. 8 moves to the right along with the piston rod two 34, the pressure in the space M in the piston cylinder three 35 is reduced, the insulin stored in the space on the left side of the piston cylinder three 35 enters the space M through the one-way valve one 38, and when the piston rod two 34 carries the piston plate two 37 to move to the left, the insulin in the space M is in a high-pressure environment, the part of insulin enters the leather tube two 36 through the one-way valve two 39, the insulin is finally transmitted into the piston cylinder one 7 through the one leather tube two 36, the blood remaining in the piston cylinder one 7 is washed, and the part of mixed liquid is transferred to the patient through the leather tube one 3 along with the right movement of the piston plate one 13 in fig. 4. In the actual use process, in order to compensate the condition that the volume of insulin is low each time, physiological saline can be supplemented additionally to ensure that enough liquid can be transferred out to flush residual blood by each movement of the piston plate I13 or the piston plate II 37.
Through the cooperation use between the above-mentioned structure, solved in the in-service use, because traditional portable automatic insulin injection device who has the function of survey blood sugar has the operation complicacy in the use, and is difficult to carry out the problem surveyed to the blood sugar fast, gives the problem of using inconvenience.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
