Diabetics and pre-diabetic patients need to regularly monitor blood glucose changes so as to control life, exercise and eating laws and reasonable medication; the glucometer is widely applied to the crowds needing to detect the blood sugar in hospitals, families and the like due to the small size, portability and accurate measurement. At present, the existing blood sugar monitoring devices adopt a blood sampling type that blood is taken from the tip of a human body for detection, and three parts of a blood sugar monitor, a blood sugar test paper and a blood sampling needle are needed.

The existing blood sugar test paper is a consumable matched with a blood sugar monitor, biological enzyme is coated on the blood sugar test paper, the existing blood sugar test paper can detect the existence amount of certain glucose in peripheral blood through reaction with the glucose in the blood, and the whole body of the blood sugar test paper is in a sheet shape; the blood taking needle is in a prick shape and is used for puncturing the skin.

Wherein, the theory of operation of current common blood glucose monitor is: glucose in blood reacts with glucose oxidase and potassium ferricyanide fixed on the surface of the test strip to generate gluconic acid and potassium ferrocyanide. The blood glucose meter applies a constant working voltage to the test strip to oxidize potassium ferrocyanide into potassium ferricyanide and generate an oxidation current, the oxidation current is in direct proportion to the concentration of glucose, and the blood glucose meter records the oxidation current and converts the oxidation current into the concentration of the glucose.

When blood sugar needs to be monitored, blood sugar test paper needs to be taken out from the test paper box, an electrode part of the blood sugar test paper, which is electrically connected with a main machine of the blood sugar monitor, is inserted into a socket on the blood sugar monitor and is in contact with an electrode of the main machine to transmit an electric signal, a blood taking needle is taken out to puncture the skin to drip blood to a blood sugar test area, and the blood sugar meter is processed by a processor in the main machine to display the converted glucose concentration on a display screen.

Example 2

In the embodiment, the improvement is made on the basis of the above embodiment, in order to ensure that the lancet can be self-destructed and ensure safety after the lancet is pressed, as shown in fig. 1, a pressing mechanism 4 is connected to the tail end of the lancet 2 in the embodiment, and the pressing mechanism 4 is located in the cavity of the blood glucose test paper 1; the contact pressure mechanism includes a fixed plug 41 and a stopper 42, wherein:

at least two stoppers 42 are arranged on the inner wall of the blood glucose test paper 1, the fixing plug 41 is fixed at the tail part of the blood taking needle 2, a bulge part 411 which is matched with the stoppers 42 is arranged on the outer wall of the fixing plug 41 so as to fix the blood taking needle at the position where the needle tip protrudes out of the front end of the blood glucose test paper, and when a user touches the blood taking needle to take blood, the fixing plug 41 can be separated from the clamping of the stoppers 42 to carry the blood taking needle 2 into the cavity of the blood glucose test paper 1;

the front end of the blood sugar test paper 1 is covered with a cover body 5 for sealing the blood taking needle 2.

Specifically, referring to fig. 1, the fixing plug 41 is preferably cylindrical, the protruding portion 411 provided on the outer wall is an arc-shaped portion, the blood collection needle 2 is mainly fixed by the slight interference fit of the fixing plug 41 and the stopper 42 on the inner wall of the blood glucose test strip, and the reaction portion is not fixed with the blood collection needle.

Specifically, the stopper 4 is provided with a groove 421 matched with the shape of the protrusion 411, at least two grooves 421 form a clamping space for clamping the fixing plug 41, and one end of the groove 421 away from the blood taking needle is formed with a step 422 abutted against the protrusion 411, so that the fixing plug 41 is fixed in the clamping space when the blood is not taken; when pressing the blood sampling, the user presses the front end of blood taking needle and gives blood taking needle a pressure, and this pressure can make fixed stopper 41 break away from the centre gripping of dog 42 and extrude the step 422 of both sides, gets into in the cavity of blood glucose test paper, and blood taking needle 2 can carry blood to be infected with and carry out the collection of blood in reaction portion 11 simultaneously, prevents that blood from dripping unable and reaction portion 11 contact. Due to the limiting action of the step 422 on the stopper 42, the fixing plug 41 cannot enter between the stoppers again, in other words, the blood collection needle 2 cannot protrude out of the front end of the blood glucose test strip 1 again. The self-destruction structure can ensure that the blood glucose test paper is abandoned after being used once, and ensure the safety of a user.

In addition to the fact that the blood contaminated on the blood collection needle can contact the reaction part 11, in order to further facilitate the reaction detection of the reaction part 11 contacting the blood, it is preferable that the reaction part at least has an absorption channel made of a siphon hydrophilic membrane (OSLO hydrophilic membrane) which is not limited in specific position on the reaction part, but the absorption channel should at least connect an end part (the end part is an end far away from the touch and press mechanism) of the reaction part 11 and the conductive part 13, and when the blood is discharged by pressing the blood collection needle with a finger, the siphon hydrophilic membrane on the reaction part can easily absorb the blood to ensure the reaction of the blood with the corresponding biological enzyme on the reaction part. The siphon hydrophilic film is made of the existing material, is a high-permeability PET (polyethylene terephthalate) polyester film treated by adopting a special super-hydrophilic technology, has a super-hydrophilic surface, and can quickly and continuously diffuse biological body fluid (such as blood). The structure of which is not described in detail herein.

Example 3

In the present embodiment, a modification is made on the basis of the above-mentioned embodiments, in order to push out the blood glucose test strip 1 under the action of the clamping mechanism for use by pressing the button 32, as an alternative embodiment, see fig. 3-6, fig. 4 is a partial enlarged schematic view at a in fig. 3, fig. 5 is a structural schematic view of closing the clamping flap, and fig. 6 is a structural schematic view of opening the clamping flap.

The above-mentioned fixture of this embodiment includes: the upper end face of the abutting part 33 is matched and abutted with the key 32, and a cavity allowing the blood glucose test paper 1 to pass through is formed in the abutting part 33;

a clamping cylinder 34 arranged at the lower part of the abutting part 33, wherein at least two clamping flaps 341 are arranged at the end part of the clamping cylinder 34 far away from the abutting part 33, the blood glucose test strip 1 can descend into a clamping space formed by the clamping flaps 341, and the clamping space is communicated with the cavity in the abutting part 33;

a limiting cap 36, which is sleeved on the periphery of the lower part of the clamping cylinder 34; when the button 32 is pressed, the abutting portion 33 drives the holding cylinder 34 to descend and extend out of the lower end of the limiting cap 36, and the holding flap 341 opens to release the blood glucose test strip 1.

Specifically, as shown in fig. 3, the accommodating cavity 31 and the sidewall of the holding mechanism are provided with a through hole (not shown) for the second electrode 37 to extend into, and the second electrode 37 of the monitoring host 3 can extend into the holding mechanism to contact with the first electrode 12 of the blood glucose test strip 1.

When the blood glucose test strip 1 is placed in the housing chamber 31 from the upper end of the housing chamber 31, the blood glucose test strip 1 falls down by gravity and falls into the holding space in the holding flap 341 through the cavity in the abutting portion 33. Similarly, a plurality of blood glucose test strips 1 can be arranged end to end in the accommodating cavity 31.

In order to push the holding cylinder 34 downward by pressing the button 32, as an alternative embodiment, as shown in fig. 3 and 4, the button 32 is horizontally disposed, and accordingly, an opening for installing the button 32 is provided on the housing of the monitoring main body 3. The lower portion of the key 32 is provided with a first inclined surface 321, the upper portion of the abutting portion 33 is provided with a second inclined surface 331 for abutting against the first inclined surface 321, and when the key 32 is pressed, the second inclined surface 331 moves downward relative to the first inclined surface 321 under the pushing of the key 32 to lower the position of the abutting portion 33.

The key 32 is used for cooperating with the abutting portion 33 to push the clamping cylinder 34 to move downwards, and simultaneously, the blood glucose test strip 1 located between the clamping flaps 341 is lowered to a position where the front end thereof extends out of the accommodating cavity 31, so as to facilitate blood sampling monitoring. It should be understood that the first electrode 12 of the blood glucose test strip 1 has a width such that when the front end of the blood glucose test strip 1 extends slightly beyond the front end of the receiving cavity 31, the first electrode 12 contacts the second electrode 37 extending into the clamping mechanism.

When the blood glucose test strip 1 extends out of the front end of the accommodating cavity 31 and the first electrode 12 is contacted with the second electrode 37 to transmit an electrochemical signal, the button 32 can be released. In order to enable the abutting portion 33 to return to its original position after the key 32 is released, as an alternative embodiment, referring to fig. 3 and 4, the abutting portion 33 is detachably connected to the limiting cap 36, and an elastic portion 35 is disposed between the abutting portion 33 and the limiting cap, and the elastic portion 35 is used for returning the abutting portion 33 and the clamping cylinder 34 when the key 32 is released.

The elastic portion 35 may be a compression spring, and the elastic force of the compression spring after deformation provides the abutting portion 33 with a return pushing force.

As an alternative embodiment, referring to fig. 4, in this embodiment, one end of the limiting cap 36 away from the abutting portion 33 is provided with a brim 361, one end of the elastic portion 35 abuts on the brim 361, and when the key 32 is pressed down, the brim 361 can abut on the bump 312 on the inner wall of the accommodating cavity 31 to prevent the limiting cap 36 and the elastic portion 35 from coming off. The diameter of the visor 361 is greater than the diameter of the cap body of the limit cap 36.

The shape of the limiting cap 36 is matched with the shape of the two clamping flaps 341, and the peripheral diameter of the limiting cap also tends to increase from one end to the other end.

The limiting cap 36 is used to fix the two ends of the elastic portion 35 together with the abutting portion 33, and to prevent the elastic portion from falling off by abutting the brim 361 against the protrusion 312 on the inner wall of the accommodating cavity 31.

In order to prevent the abutment 33 from descending too much and even falling out of the accommodating cavity 31 when the key 32 is pressed, as an alternative embodiment, referring to fig. 4, the abutment 33 is provided with a limit step 332, the inner wall of the accommodating cavity 31 is provided with a boss 311 for abutting against the limit step 332, and when the key 32 is pressed, the lower edge of the limit step 332 can abut against the upper edge of the boss 311 to limit the position of the abutment 33.

By the engagement of the stopper step 332 with the boss 311 in the housing chamber 31, the contact portion 33 and the grip cylinder 34 can be prevented from being lowered too much, and the contact portion 33 and the grip cylinder 34 can be prevented from being separated from the housing chamber 31.

The blood glucose monitoring integrated device integrates the monitoring host machine 3, the blood glucose test paper 1 and the blood taking needle 2, the accommodating cavity 31 in the monitoring host machine 3 can store the blood glucose test paper 1, and the blood glucose test paper 1 in the accommodating cavity 31 can be released through the matching of the key 32 and the clamping mechanism; when the blood glucose test paper 1 protrudes out of the accommodating cavity 31, the cover body 5 can be taken down, the front end of the blood taking needle 2 is pressed, the pressing device is pressed, the fixing plug 41 is separated from the clamping of the stop block 42 and carries the blood taking needle 2 to fall into the cavity of the blood glucose test paper 1, and meanwhile, the blood taking needle 2 carries blood to be infected to the reaction part 11 to collect blood information; after the blood glucose test paper 1 at the lowest part is used, the key 32 can be pressed down and completely taken out for discarding, so that cross contamination is prevented, and meanwhile, the adjacent blood glucose test paper 1 at the upper part in the accommodating cavity 31 falls into the clamping mechanism for standby.
