Description

Combined blood glucose meter

The present invention relates to a blood glucose meter, in particular to a composite blood glucose meter.

Diabetic patients need to measure their blood sugar levels regularly. When measuring blood sugar, they usually press a one-press blood collection needle first, and use the needle tip that protrudes when pressed to pierce the human skin to obtain a drop of blood, and then place the blood drop on another independent test paper; then, the test paper is sent to a blood glucose meter for measurement to read the blood sugar value.

For health and safety reasons, disposable blood collection needles with a pressing structure are usually used to avoid the reuse of the needle tip of the blood collection needle. In addition, each test strip can only be used once. Therefore, patients need to prepare a large number of disposable blood collection needles and test strips separately, which is relatively unenvironmental and needs further improvement.

Therefore, the object of the present invention is to provide a composite blood glucose meter that can at least overcome the shortcomings of the prior art.

Therefore, the composite blood glucose meter of the present invention is suitable for measuring the blood glucose value of a drop of blood, and comprises a blood glucose meter unit and a test strip unit.

The blood glucose meter unit includes a housing extending forward and backward along a length direction, a mobile seat assembly movably disposed on the housing along the length direction and having a receiving slot, a host movably disposed in the receiving slot of the mobile seat assembly along the length direction, and an elastic pressing assembly connected to the rear side of the mobile seat assembly. The housing is formed with an insertion hole penetrating the front side, and the elastic pressing assembly has an elastic restoring force moving away from the insertion hole.

The test strip unit includes a needle-containing test strip. The needle-containing test strip has a test strip body and a blood collection needle connected to the test strip body. The needle-containing test strip is suitable for passing through the insertion hole and being inserted into the host, so that the host can measure the blood sugar value of the blood drop on the needle-containing test strip.

The utility of the present invention is that: by utilizing the design of the needle-containing test strip and the blood glucose meter unit, the needle-containing test strip can utilize the elastic pressure group of the blood glucose meter unit to pierce the skin and collect blood, and the needle-containing test strip can integrate the blood collection needle and test paper of the current technology. Thus, the present invention does not need to prepare the pressure-type blood collection needle and test paper separately, but only needs to prepare the integrated needle-containing test strip, and the elastic pressure group can be reused, which is very environmentally friendly and innovative.

1 and 3 , an embodiment of the composite blood glucose meter of the present invention is suitable for measuring the blood glucose value of a drop of blood. The composite blood glucose meter comprises a blood glucose meter unit 1 and a test strip unit 2 .

1, 2 and 4, the blood glucose meter unit 1 includes a housing 11 extending forward and backward along a length direction L, a mobile seat assembly 12 movably disposed in the housing 11 along the length direction L, a host 13 disposed in the housing 11 and capable of being driven by the mobile seat assembly 12 to move forward and backward, an elastic pressure assembly 14 connected to the rear side of the mobile seat assembly 12, and a display screen 15.

The housing 11 includes an outer shell 111 that is generally rectangular and extends forward and backward along the longitudinal direction L, and a fixed wall 112 fixedly arranged on the outer shell 111. The outer shell 111 defines a containing space 113, a plug hole 114 that passes through the front side, a pressing hole 115 that passes through the rear side, and a hole wall surface 116 that defines an elongated hole 117 that passes through the top side. The plug hole 114 is a rectangular extending left and right, and its height H gradually decreases from front to back. The hole wall surface 116 has a first face 118 and a second face 119 that are spaced from each other forward and backward in the longitudinal direction L; the elongated hole 117 extends forward and backward in the longitudinal direction L. The insertion hole 114, the pressing hole 115, and the elongated hole 117 are connected to the accommodating space 113. The fixed wall portion 112 is located in the accommodating space 113, behind the elongated hole 117 and the insertion hole 114, and in front of the pressing hole 115, and is formed with a through hole 110 that penetrates from front to back.

The mobile seat assembly 12 has a bottom wall 121, and a first side wall 122, a second side wall 123, and a third side wall 124 extending upward from the bottom wall 121 and arranged in a front-to-back manner in the longitudinal direction L. The bottom wall 121, the first side wall 122, and the second side wall 123 together define a receiving groove 125. The first side wall 122 is formed with a through hole 126 that is transversely long and passes through from front to back, and the position of the through hole 126 corresponds to the insertion hole 114. In the projection from top to bottom, the long hole 117 on the top side of the housing 11 is located between the first side wall 122 and the second side wall 123.

The host 13 is used to measure the blood sugar level of a drop of blood and generate a measurement signal with the blood sugar level. The host 13 can move along the length direction L and has a body 131 that can be movably placed in the container 125, and a control part 132 that extends upward from the top of the body 131 and extends through the long hole 117. When the control part 132 is controlled to move along the length direction L in the long hole 117, the host 13 as a whole can move forward and backward in the length direction L relative to the moving seat.

Referring to FIG. 4, FIG. 5, and FIG. 7, the host 13 can move between a first position (as shown in FIG. 4), a second position (as shown in FIG. 5), and a third position (as shown in FIG. 7) relative to the mobile seat assembly 12. In the first position, the control portion 132 abuts against the first face portion 118, and the body portion 131 abuts against the first side wall 122, so that the test piece body 221 protrudes out of the housing 11. In the second position, the body portion 131 abuts against the second side wall 123, and the control portion 132 abuts against the second face portion 119. In the third position, the control portion 132 is located between the first face portion 118 and the second face portion 119, and the body portion 131 is located between the first side wall 122 and the second side wall 123 at a distance.

Referring to Fig. 1, Fig. 2, and Fig. 4, the elastic pressing assembly 14 has a rod 141 extending forward and backward and fixedly connected to the third side wall 124 by a bolt 91, a pressing portion 142 connected to the rod 141 and provided for pressing, and an elastic member 143 set on the rod 141. The rod 141 is movably inserted through the through hole 110 of the fixed wall 112. The pressing portion 142 is integrally connected to an end of the rod 141 opposite to the third side wall 124, and is located in the pressing hole 115 of the housing 11 and exposed from the housing 11. The elastic member 143 is a spring and elastically presses between the fixed wall portion 112 and the pressing portion 142. Thus, the elastic pressing assembly 14 is linked to the moving seat assembly 12 and has an elastic restoring force to move away from the insertion hole 114.

5 and 6 , the elastic pressing assembly 14 is subjected to elastic force and can be switched between a non-pressing state (as shown in FIG. 5 ) and a pressing state (as shown in FIG. 6 ) relative to the housing 11 .

When the elastic pressing assembly 14 is in the non-pressing state, the first side wall 122 is spaced apart from the outer shell 111 in the length direction L.

When the elastic pressing assembly 14 is in the pressing state, the elastic pressing assembly 14 is subjected to a forward force and moves forward relative to the housing 11 , and drives the first side wall 122 of the moving base assembly 12 to press against the outer housing 111 .

When the elastic pressing assembly 14 is switched from the pressing state to the non-pressing state, the rod portion 141 is subjected to the elastic force and moves backward relative to the housing 11, driving the moving seat assembly 12 to move backward and return to its original position.

The display screen 15 is disposed on the top side of the housing 11 and is signal-connected to the host 13. The display screen 15 can display the blood sugar value when receiving the measurement signal.

2 to 4 , the test strip unit 2 is disposable and includes a transparent and elongated test strip box 21 , and a needle-containing test strip 22 and an alcohol cotton swab 23 removably accommodated in the test strip box 21 .

The test strip box 21 has a main box portion 211, a first removal portion 212 that is tearably connected to the rear side of the main box portion 211, and a second removal portion 213 that is tearably connected to the front side of the main box portion 211. The main box portion 211 and the first removal portion 212 together define a first space 214 for accommodating the needle-containing test strip 22. The main box portion 211 and the second removal portion 213 together define a second space 215 that is spaced from the first space 214 and for accommodating the alcohol cotton swab 23.

The manufacturing of the test strip box 21 mainly includes placing a sub-box 202 located at the front side and with an opening facing forward in a box body 201; and then using a tear line (dotted line) tool to form a first tear line 203 that can distinguish the main box part 211 from the first removal part 212, and a second tear line 204 that can distinguish the main box part 211 from the second removal part 213. By using the arrangement of the sub-box 202, the second space 215 and the first space 214 are separated from each other in front and back.

The needle-containing test strip 22 has a flat test strip body 221 located at the front and extending forward and backward, a blood collection needle 222 located at the rear and provided for blood collection, and an embedding strip 223 directly connected between the test strip body 221 and the blood collection needle 222, so that the blood collection needle 222 is connected to the test strip body 221.

The longitudinal section of the embedding strip 223 is roughly triangular in shape, and the thickness T of the longitudinal section gradually increases from the test strip body 221 toward the blood collection needle 222. The test strip body 221 is formed with a third tear line 224, so that the embedding strip 223 can be detachably connected to the test strip body 221.

3 and 4 , when in use, first, a user (not shown) moves the control unit 132 to abut against the first surface 118 , so that the host 13 is located at the first position.

In addition, the first removal portion 212 is torn off along the first tear line 203, and the needle-containing test strip 22 is taken out from the test strip box 21; then, the test strip body 221 of the needle-containing test strip 22 passes through the insertion hole 114 of the housing 11 and the through hole 126 of the mobile base assembly 12, and is inserted into the host 13 located at the first position.

Referring to FIG. 5 , the user (not shown) moves the control unit 132 to abut against the second surface 119, so that the host 13 is located at the second position, and the first side wall 122 of the mobile base assembly 12 is spaced apart and located behind the housing 11. At this time, the rear half of the embedding strip 223 is embedded in the through hole 126, and the front half is located in the insertion hole 114; and the elastic pressing assembly 14 is in the non-pressing state, so that the blood collection needle 222 is retracted and does not protrude from the housing 111.

3 , at this time, the second removal portion 213 can be torn off along the second tear line 204, and the alcohol cotton 23 can be taken out from the test strip box 21. The alcohol cotton 23 is used to disinfect a finger of a test subject (not shown, and the test subject and the user can be the same person).

Referring to FIG. 5 and FIG. 6 , the blood glucose meter unit 1 is then gently placed against a sterilized finger, with the blood collection needle 222 facing the finger, and the pressing portion 142 is pressed to switch the elastic pressing assembly 14 from the non-pressing state to the pressing state. In the pressing state, the rod 141 of the elastic pressing assembly 14 pushes the moving seat assembly 12 forward to abut against the housing 11. Since the host 13 is maintained at the second position abutting against the second side wall 123, it is driven forward by the moving seat assembly 12, and the blood collection needle 222 of the needle-containing test strip 22 embedded in the perforation 126 protrudes out of the housing 111, piercing the finger skin to drip blood.

Referring to FIG. 4 , finally, the finger is moved away from the blood glucose meter unit 1, and the pressing portion 142 is no longer pressed, and the host 13 is moved to the first position, and the needle-containing test strip 22 located on the host 13 is pushed forward, so that the embedding strip 223 is pushed away from the perforation 126, and the test strip body 221 is exposed from the housing 11, and blood on the skin is dripped onto the test strip body 221; the host 13 analyzes the blood glucose level and generates a measurement signal; the measurement signal is transmitted to the display screen 15 to display the blood glucose level, and the blood glucose test is completed.

Referring to FIG. 3 and FIG. 7 , it should be noted that the user can also use the control unit 132 to move the host 13 to the third position opposite to a score line 16 (as shown in FIG. 1 ) on the housing 11. In the third position, the embedding strip 223 moves away from the through hole 126 and protrudes out of the housing 11. At this time, the embedding strip 223 is torn or broken apart along the third tear line 224, so that the embedding strip 223 is separated from the test strip body 221 inserted in the host 13 and discarded. In this way, the used blood collection needle 222 can be prevented from stabbing other people and preventing the occurrence of diseases transmitted through the bloodstream.

After completing the blood sugar measurement, the control unit 132 can be used to move the host 13 to the first position, so that the used test strip body 221 can be taken out and discarded.

In summary, since the blood collection needle 222 and the test strip body 221 are connected together by the embedding strip 223, and the embedding strip 223 can be embedded in the perforation 126 when the host 13 is in the second position, the needle-containing test strip 22 can pierce the skin and collect blood by the elastic pressure group 14 of the blood glucose meter unit 1. In this way, the present invention does not need to prepare a pressure-type blood collection needle and a test strip separately, but only needs to prepare the integrated needle-containing test strip 22, and the elastic pressure group 14 provided in the blood glucose meter unit 1 can be repeatedly used, which is very simple and environmentally friendly, so the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
