Background

In recent years, the incidence of diabetes has been on the rise. The diabetic patients and pre-diabetic patients need to regularly monitor the blood sugar changes so as to control the life, exercise, diet and reasonable medication; blood glucose meters are widely used in hospitals, families and the like for people who need to detect blood glucose because of their small size and portability and accurate measurement. At present, the existing blood glucose monitoring devices all adopt blood sampling type for taking blood from the human body terminal to detect, and the existing blood glucose monitoring devices need three components of a blood glucose monitor, blood glucose test paper and a blood taking needle.

The existing blood glucose test paper is matched with a blood glucose monitor, biological enzymes are coated on the blood glucose test paper, and certain consumable materials for detecting the existence of glucose in peripheral blood can be reacted with glucose in blood, so that the whole blood glucose test paper is in a flake shape; the blood taking needle is cone-shaped 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 immobilized on the surface of the test strip to produce gluconic acid and potassium ferrocyanide. The glucometer applies a constant working voltage to the test strip to oxidize potassium ferrocyanide into potassium ferricyanide to generate oxidation current, the oxidation current is proportional to the glucose concentration, the glucometer records the oxidation current and converts the glucose concentration.

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 used for being electrically connected with a host computer of the blood sugar monitor, is inserted into a socket on the blood sugar monitor and is contacted with an electrode of the host computer to transmit an electric signal, a blood taking needle is taken out to puncture the skin to drop blood into a blood sugar test paper test area, and the blood sugar monitor is processed by a processor in the host computer and then displays the converted glucose concentration on a display screen.

The blood glucose test strip 1 is a hollow columnar body, and the reaction part 11 is provided on the inner wall of the blood glucose test strip 1, wherein the lancet 2 is cone-shaped and is used for puncturing the skin (usually finger skin). The blood lancet 2 is disposed in the blood glucose test paper 1 and located at an end far from the first electrode 12, thereby preventing contamination.

As an alternative embodiment, referring to fig. 3, the diameter of the housing chamber 31 is used to house a single blood glucose test strip 1 such that a plurality of blood glucose test strips 1 are arranged in the housing chamber 31 end to end, and an end of the blood glucose test strip 1 remote from the lancet 2 is provided with an isolation layer 14 (as shown in fig. 1 and 2) for closing the end of the blood glucose test strip 1.

The diameter of the receiving chamber 31 may be slightly larger than the diameter of the blood glucose test strips 1, but should be smaller than the diameters of the two blood glucose test strips 1. The isolation layer 14 may be an isolation film with an isolation effect and capable of preventing pollution, and may be a plastic film, an aluminum film, or the like, and is not limited in material, but should be capable of isolating blood glucose test strips 1 arranged end to end, and sealing the end of the blood glucose test strip, so as to prevent the lowest blood glucose test strip 1 from causing cross contamination of the rest of the blood glucose test strips 1 in the accommodating cavity 31 during monitoring.

Specifically, the above-mentioned separator may be adhered to the end face of the blood glucose test paper 1.

Preferably, the length of the accommodating chamber 31 is equal to or slightly greater than the length of 4 or 5 blood glucose strips 1.

Example 2

In order to facilitate self-destruction of the blood taking needle and ensure safety after the blood taking of the touch blood taking needle is completed, as shown in fig. 1, the tail end of the blood taking needle 2 in the embodiment is connected with a touch mechanism 4, and the touch mechanism 4 is positioned in a cavity of the blood glucose test paper 1; the pressing 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, a fixing plug 41 is fixed on the tail part of the blood taking needle 2, a protruding part 411 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 of the tip protruding 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 a cavity of the blood glucose test paper 1;

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

Specifically, referring to fig. 1, the fixing plug 41 is preferably cylindrical, the protruding portion 411 disposed on the outer wall thereof is an arc portion, and the fixing of the lancet 2 is mainly performed by micro-interference fit between the fixing plug 41 and the stopper 42 on the inner wall of the blood glucose test strip, wherein the reaction portion does not fix the lancet.

Specifically, the stopper 4 is provided with grooves 421 matching the shape of the protruding portions 411, at least two grooves 421 form a clamping space for clamping the fixing plug 41, one end of the groove 421 away from the blood taking needle is formed with a step 422 abutting against the protruding portions 411, and the fixing plug 41 is fixed in the clamping space when no blood is taken; when the blood collection is touched and pressed, a user presses the front end of the blood collection needle to give the blood collection needle a pressure, the pressure can enable the fixing plug 41 to be separated from the clamping of the stop block 42 and press the steps 422 on two sides, the blood collection needle enters the cavity of the blood glucose test paper, and meanwhile the blood collection needle 2 can carry blood to be stained on the reaction part 11 for blood collection, and blood dripping is prevented from being unable to contact with the reaction part 11. Due to the limit of the step 422 on the stopper 42, the fixing plug 41 cannot be re-inserted between the stoppers, in other words, the lancet 2 cannot be re-protruded from the front end of the blood glucose test strip 1. The self-destruction structure can ensure that the blood glucose test paper is abandoned after being used once, and ensure the safety of users.

In addition to the blood stained on the lancet being able to contact the reaction part 11, in order to further facilitate the reaction detection by the reaction part 11 contacting the blood, it is preferable that the reaction part has at least an absorption channel made of a siphon hydrophilic film (OSLO hydrophilic film), the specific position of which on the reaction part is not limited, but the absorption channel should connect at least the end of the reaction part 11 (the end being the end far from the contact mechanism) and the conductive part 13, and when the lancet is pressed by a finger to bleed, the siphon hydrophilic film on the reaction part is easy to absorb the blood to ensure the reaction of the blood with the corresponding bio-enzyme on the reaction part. The siphon hydrophilic film is a high-permeability PET (polyethylene terephthalate) polyester film treated by a special super-hydrophilic technology, has a super-hydrophilic surface, and can enable biological fluid (such as blood) to diffuse rapidly and continuously. The structure thereof will not be described in detail herein.

The cover body 5 is buckled at the front end of the blood glucose test paper 1 to seal the blood taking needle 2, so that accidental injury is prevented when the blood taking needle is not used, and the cover body is opened to expose the blood taking needle when the blood taking needle is ready to start working.

In this embodiment, when the lancet 2 and the fixing plug 41 are separated from the holding of the stopper 42, the lancet 2 enters the cavity of the blood glucose test paper 1, the front end of the lancet 2 no longer extends out of the end of the blood glucose test paper 1, and the lancet 2 and the fixing plug 41 will not be separated due to the sealing of the other end of the blood glucose test paper 1.

Example 3

This embodiment is an improvement on the above embodiment, and in order to push out the blood glucose test paper 1 under the action of the clamping mechanism by pressing the key 32, as an alternative embodiment, see fig. 3-6, fig. 4 is a schematic enlarged view of part of the portion a in fig. 3, fig. 5 is a schematic view of the structure of the clamping flap being closed, and fig. 6 is a schematic view of the structure of the clamping flap being opened.

The clamping mechanism of the embodiment comprises: an abutting portion 33, the upper end surface of which is adapted to be abutted against the key 32, the abutting portion 33 having a cavity formed therein for allowing the blood glucose test paper 1 to pass therethrough;

a holding cylinder 34 provided at the lower part of the abutting part 33, wherein at least two holding flaps 341 are provided at the end part of the holding cylinder 34 away from the abutting part 33, and the blood glucose test paper 1 can be lowered into a holding space formed by the holding flaps 341, and the holding space is communicated with a cavity in the abutting part 33;

a limit cap 36 sleeved on the lower periphery of the clamping cylinder 34; when the key 32 is pressed, the abutting portion 33 drives the clamping cylinder 34 to descend and extend out of the lower end of the limit cap 36, and the clamping valve 341 opens to release the blood glucose test paper 1.

Specifically, referring to fig. 3, the side wall of the accommodating cavity 31 and the clamping mechanism is provided with a through hole (not shown) into which the second electrode 37 extends, and the second electrode 37 of the monitoring host 3 can extend into the clamping mechanism to contact with the first electrode 12 of the blood glucose test paper 1.

When the blood glucose test strip 1 is placed in the accommodation chamber 31 from the upper end of the accommodation chamber 31, the blood glucose test strip 1 falls down due to gravity and falls into the clamping space in the clamping flap 341 through the chamber in the abutment 33. Similarly, a plurality of blood glucose test strips 1 may be sequentially arranged in the housing chamber 31 end to end.

In order to push the holding cylinder 34 downward by pressing the key 32, as an alternative embodiment, as shown in fig. 3 and 4, the key 32 is horizontally disposed, and correspondingly, an opening for mounting the key 32 is provided in the housing of the monitoring host 3. The lower part of the key 32 is provided with a first inclined surface 321, and the upper part of the abutting part 33 is provided with a second inclined surface 331 for abutting against the first inclined surface 321, and when the key 32 is pressed down, the second inclined surface 331 moves down compared with the first inclined surface 321 under the pushing of the key 32 so as to lower the position of the abutting part 33.

The key 32 cooperates with the abutting portion 33 to push the clamping cylinder 34 downward, and simultaneously, the blood glucose test paper 1 located between the clamping flaps 341 is lowered to a position where the front end of the blood glucose test paper extends out of the accommodating cavity 31, so that blood sampling monitoring is facilitated. It will be appreciated that the first electrode 12 of the blood glucose test strip 1 has a range of widths such that when the front end of the blood glucose test strip 1 extends slightly beyond the front end of the receiving chamber 31, the first electrode 12 is in contact with the second electrode 37 which extends into the clamping mechanism.

In order that the clamping flap 341 can release the blood glucose test paper 1 when the clamping cylinder 34 is lowered, as an alternative embodiment, as shown in fig. 3 to 6, a gap exists between the two clamping flaps 341, and the peripheral diameter formed by the two clamping flaps 341 tends to increase from one end near the abutment 33 to the other end.

Preferably, the clamping flap 341 may be made of plastic, and the like, and can be received or opened by the limiting action of the limiting cap 36. Specifically, referring to fig. 4, 5 and 6, when the limiting cap 36 is pushed down to be clamped to the lower part of the clamping petals 341, the two clamping petals 341 are limited by the limiting cap 36, and the clamping space of the clamping petals can just clamp the blood glucose test paper 1 to prevent the blood glucose test paper from falling out of the accommodating cavity 31, as shown in fig. 5; when the key 32 is pressed, the abutting portion 33 pushes the holding cylinder 34 to descend, the two holding flaps 341 move downward to be separated from the holding of the limit cap 36 and open, as shown in fig. 6, the range of the holding space is increased, and the blood glucose test paper 1 can be released and extended out of the accommodating chamber 31.

The key 32 is released when the blood glucose test strip 1 extends out of the front end of the housing chamber 31 and the first electrode 12 is in contact with the second electrode 37 for transmitting an electrochemical signal. In order to enable the abutment 33 to return after the key 32 is released, as an alternative embodiment, as shown in fig. 3 and 4, the abutment 33 is detachably connected to the limit cap 36, and an elastic portion 35 is disposed between the abutment 33 and the limit cap, and the elastic portion 35 is used for returning the abutment 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 after the compression spring is deformed may provide a restoring thrust to the abutting portion 33.

As an alternative embodiment, referring to fig. 4, a cap peak 361 is disposed at an end of the limiting cap 36 away from the abutting portion 33, an end of the elastic portion 35 abuts against the cap peak 361, and when the key 32 is pressed, the cap peak 361 can abut against the protrusion 312 on the inner wall of the accommodating cavity 31 to prevent the limiting cap 36 and the elastic portion 35 from being separated. The diameter of the cap bill 361 is larger than the diameter of the cap body of the limit cap 36.

The shape of the limiting cap 36 is adapted to 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 engaged with the abutting portion 33 to fix both ends of the elastic portion 35, and is abutted against the protrusion 312 on the inner wall of the accommodating chamber 31 through the cap peak 361 to prevent the elastic portion from being separated.

In order to prevent the contact portion 33 from being lowered too much or even falling out of the accommodating chamber 31 when the key 32 is pressed, as an alternative embodiment, as shown in fig. 4, a limiting step 332 is provided on the contact portion 33, a boss 311 for abutting against the limiting step 332 is provided on the inner wall of the accommodating chamber 31, and when the key 32 is pressed, the lower edge of the limiting step 332 can abut against the upper edge of the boss 311 to limit the position of the contact portion 33.

By the engagement of the above-described stopper step 332 and the boss 311 in the accommodating chamber 31, the contact portion 33 and the clamp cylinder 34 can be prevented from being excessively lowered, and the contact portion 33 and the clamp cylinder 34 can be prevented from being separated from the accommodating chamber 31.

According to the integrated blood glucose monitoring device, the monitoring host 3, the blood glucose test paper 1 and the blood taking needle 2 are integrated, the accommodating cavity 31 in the monitoring host 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 cooperation 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 removed, the front end of the blood taking needle 2 is pressed, the touch device is stressed, the fixing plug 41 is separated from the clamping of the stop block 42, so that the blood taking needle 2 falls into the cavity of the blood glucose test paper 1, and meanwhile, the blood taking needle 2 is stained with blood to the reaction part 11 to collect blood information; after the lowest blood glucose test paper 1 is used, the key 32 can be pressed to be completely taken out and discarded, so that cross contamination is prevented, and meanwhile, the adjacent upper blood glucose test paper 1 in the accommodating cavity 31 falls into the clamping mechanism for standby.

The particular features, structures, or characteristics may be combined in any suitable manner in any one or more embodiments or examples in this specification.
