[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] like Figure 1-Figure 3 As shown, a connection mechanism 1 provided in an embodiment of the present invention is provided on a transmitter, and the connection mechanism 1 includes:

[0033] A first connecting portion 11 is connected to the transmitter and has a disc-shaped structure;

[0034] The second connecting part 12 is configured as a cylindrical structure, and the blood glucose detector 2 is installed on the outer bottom surface of the second connecting part 12; the cross-section of the first connecting part 11 is adapted to the cross-section of the inner space of the cylinder of the second connecting part 12, and a first protrusion 121 is provided on the inner wall of the cylinder of the second connecting part 12, and a notch 111 is provided on the edge of the first connecting part 11 to match the first protrusion 121; by aligning the first protrusion 121 with the notch 111, the first connecting part 11 can be embedded in the cylinder of the second connecting part 12 or the first connecting part 11 can be taken out from the cylinder of the second connecting part 12, and after the first connecting part 11 is embedded in the cylinder of the second connecting part 12, the two can rotate relative to each other.

[0035] In this embodiment, a first connecting rod and a first connecting hole are provided on the first connecting part 11, and a second connecting hole and a second connecting rod are correspondingly provided on the pullback mechanism 5 of the launcher. The first connecting rod is connected to the second connecting hole, and the second connecting rod is connected to the first connecting hole, so that the first connecting part 11 can be connected to the launcher; when in use, the user aligns the notch 111 with the first protrusion 121 and then pushes the first connecting part 11 into the cylinder of the second connecting part 12. When the first connecting part 11 reaches the inner bottom surface of the second connecting part 12, the user rotates the second connecting part 12 relative to the first connecting part 11, so that the notch 111 and the first protrusion 121 are staggered, thereby making the first protrusion 1 21 forms a limit on the first connecting part 11; after use, the user rotates the second connecting part 12 to realign the notch 111 with the first protrusion 121, releases the limit on the first connecting part 11, and then pulls back the second connecting part 12 to separate the first connecting part 11 and the second connecting part 12; in the present application, after the user aligns the first protrusion 121 with the notch 111, the second connecting part 12 equipped with the blood glucose detector 2 can be merged / separated with the first connecting part 11, and when merging, the second connecting part 12 can be rotated so that the two rotate relative to each other to make the second connecting part 12 firmly connected to the first connecting part 11. The operation is simple and quick, and can significantly improve the installation efficiency of the blood glucose detector 2.

[0036] As a preferred embodiment, the first connecting portion 11 is disc-shaped, the second connecting portion 12 is cylindrical, and the diameter of the first connecting portion 11 does not exceed the diameter of the cross section of the space inside the second connecting portion 12 .

[0037] The first protrusion 121 is arranged flush with the upper edge of the cylindrical wall of the second connecting part 12, and the distance between the surface of the first protrusion 121 facing the inner bottom surface of the second connecting part 12 and the inner bottom surface is just greater than the thickness of the first connecting part 11, so that when the first protrusion 121 forms a limit on the first connecting part 11, the first connecting part 11 will not shake in the second connecting part 12.

[0038] In this embodiment, the cross-section of the first connecting part 11 and the cross-section of the space inside the cylinder of the second connecting part 12 are both circular, so that the first connecting part 11 can rotate relative to the second connecting part 12, and the sizes of the two are just adapted, so that when the first connecting part 11 is embedded in the second connecting part 12, no relative movement will occur in the radial direction. In addition, since the first protrusion 121 limits the radial position of the first connecting part 11, the first connecting part 11 cannot move relative to the radial direction after being installed in place, so that the first connecting part 11 and the second connecting part 12 can be firmly connected.

[0039] like Figures 1-4As shown, as a preferred embodiment, a first through hole 112 is provided on the first connecting part 11, and a second through hole 122 is provided on the second connecting part 12 corresponding to the first through hole 112; when the first connecting part 11 and the second connecting part 12 are connected in place, the first through hole 112 is aligned with the second through hole 122, and the trigger rod of the transmitter's retraction mechanism 5 passes through the first through hole 112 and the second through hole 122 and extends through the connecting mechanism 1 to a position in the same plane as the blood glucose detector 2. When the blood glucose detector 2 on the connecting mechanism 1 is attached to the human skin, the trigger rod is triggered by force at the same time, so that the retraction mechanism 5 drives the connecting mechanism 1 to pull back, so that the connecting mechanism 1 is separated from the blood glucose detector 2.

[0040] A second protrusion 113 is provided on the first connecting portion 11 for limiting the range of relative rotation of the second connecting portion 12 and the first connecting portion 11. When the second connecting portion 12 is subjected to force and rotates relative to the first connecting portion 11 until the first protrusion 121 contacts the second protrusion 113, the first through hole 112 and the second through hole 122 are opposite to each other.

[0041] In this embodiment, the second protrusion 113 is arranged so that the first connecting part 11 and the second connecting part 12 can only rotate relative to each other at a certain angle. At this time, the first connecting part 11 and the second connecting part 12 are firmly connected, and the first through hole 122 is just aligned with the second through hole 122; the coordinated arrangement of the first through hole 112 and the second through hole 122 realizes the stable connection of the connecting machine without hindering the operation of the trigger rod in the pullback mechanism 5, that is, it ensures the pullback effect of the transmitter on the connecting mechanism 1 after completing the launch of the blood glucose detector 2, so as to realize the recycling of the connecting mechanism 1.

[0042] like Figure 5 As shown, as a preferred embodiment, a buckle 123 is provided at the bottom of the second connecting part 12, and the buckle 123 first cooperates with the slot on the blood glucose detector 2, and the blood glucose detector 2 is connected to the second connecting part 12 by snapping the buckle 123 into the slot.

[0043] In this embodiment, a card slot that cooperates with the buckle 123 is provided on the blood glucose detector 2. During installation, the user can directly insert the buckle 123 into the card slot, so that the blood glucose detector 2 is connected to the bottom of the second connecting part 12.

[0044] like Figure 6-Figure 7 As shown, the embodiment of the present invention further provides a transmitter, the transmitter comprising:

[0045] The launch tube 3 is a cylindrical structure with one end open;

[0046] The launching mechanism 4 is provided on the launching tube 3 and is used for launching the blood glucose detector 2;

[0047] The pulling back mechanism 5 is arranged in the reflecting tube and connected to the transmitting mechanism 4. The connecting mechanism 1 is connected to the pulling back mechanism 5. The blood glucose detector 2 is connected to the connecting mechanism 1. After the blood glucose detector 2 is ejected into place, the pulling back mechanism 5 pulls back the connecting mechanism 1 to separate the connecting mechanism 1 from the blood glucose detector 2.

[0048] In this embodiment, a through hole is provided on the launching tube 3, so that the launching mechanism 4 arranged outside the launching tube 3 is connected to the retraction mechanism 5 arranged inside the launching tube 3; after the user installs the blood glucose detector 2 on the connecting mechanism 1, the connecting mechanism 1 and the retraction mechanism 5 are connected into place, and then the launching mechanism 4 is started when in use, so that the retraction mechanism 5 and the connecting mechanism 1 are ejected together. During the ejection process, the retraction mechanism 5 is always connected to the launching tube 3, and after the blood glucose detector 2 is ejected into place, the retraction mechanism 5 pulls back the connecting mechanism 1 to separate the connecting mechanism 1 from the blood glucose detector 2; in this application, the installation operation of the connecting mechanism 1 is simple and quick, and the blood glucose detector 2 can be quickly installed on the launcher to improve the installation and detection efficiency.

[0049] like Figure 6-Figure 7 As shown, the embodiment of the present invention further provides a blood glucose detection device, the device comprising:

[0050] transmitter;

[0051] The connecting mechanism 1 connected to the transmitter;

[0052] The blood glucose detector 2 is connected to the second connecting portion 12 of the connecting mechanism 1 .

[0053] In the present application, by setting the detachable first connecting part 11 and the second connecting part 12 of the connecting mechanism 1, the user can merge / separate the second connecting part 12 equipped with the blood glucose detector 2 with the first connecting part 11 after aligning the first protrusion 121 with the notch 111, and rotate the second connecting part 12 when merging so that the two rotate relative to each other, so that the second connecting part 12 can be firmly connected to the first connecting part 11. The operation is simple and quick, and can significantly improve the installation efficiency of the blood glucose detector 2.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
