Detailed implementation mode

[0056] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be 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 utility model and are not used to limit the present utility model.

[0057] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0058] As Figure 1 shown, a transmitter provided by an embodiment of the present utility model includes:

[0059] A launching tube 1, the launching tube 1 is a tubular structure with one end open;

[0060] A launching mechanism, the launching mechanism is arranged in the launching tube 1 and is used for ejecting the blood glucose detector 5; the launching mechanism includes a power member, an ejection part 2 and a triggering assembly, the power member is used to provide power for the launching of the launching mechanism, the ejection part 2 is in transmission connection with the power member, and the triggering assembly is arranged outside the launching tube 1 and is used for starting the ejection action;

[0061] A pulling-back mechanism 3, the pulling-back mechanism 3 is arranged on the ejection part 2 and is used for pulling back the mounting plate 4 after the blood glucose detector 5 is ejected in place, so that the mounting plate 4 is separated from the blood glucose detector 5, so as to facilitate the installation of another blood glucose detector 5;

[0062] The mounting plate 4, the mounting plate 4 is connected with the pulling-back mechanism 3, and a mounting position for mounting the blood glucose detector 5 is arranged on the mounting plate 4, and the mounting position faces the open end of the launching tube 1.

[0063] In this embodiment, after the user presses the trigger assembly, the power component generates power, which then pushes the ejection part 2, causing the ejection part 2 to eject, and then driving the mounting plate 4 and the blood glucose detector 5 mounted on the mounting plate 4 to move, so that the blood glucose detector 5 adheres to the human skin. Subsequently, the pulling mechanism 3 connected between the mounting plate 4 and the ejection part 2 applies a pulling force to the mounting plate 4, separating the mounting plate 4 from the blood glucose detector 5; in this application, after the blood glucose detector 5 is ejected in place, the transmitter can pull back the mounting plate 4 on which the blood glucose detector 5 is mounted to install other blood glucose detectors 5, that is, the recycling of the mounting plate 4 can be realized, reducing waste.

[0064] As Figures 1 - 3 shown, as a preferred embodiment, the power component is the first spring 26. One end of the first spring 26 abuts against the inner bottom surface of the launch tube 1, and the other end abuts against the ejection part 2.

[0065] The ejection part 2 is a cylindrical structure with an opening facing the inner bottom surface of the launch tube 1. The ejection part 2 is provided with an inner tube wall 22 and an outer tube wall 21. The first spring 26 extends into the groove formed by the inner tube wall 22 and the outer tube wall 21 and abuts against the bottom surface of the ejection part 2.

[0066] A sliding groove 23 and a limiting groove 24 are formed on the outer tube wall 21. A slide rail 11 matching the sliding groove 23 and a first limiting part 12 in interference fit with the limiting groove 24 are provided on the inner wall of the launch tube 1; by fitting the sliding groove 23 and the slide rail 11, the ejection part 2 can slide in the launch tube 1. When the ejection part 2 slides to the inner bottom surface of the launch tube 1, the limiting groove 24 is fitted with the first limiting part 12.

[0067] In this embodiment, when the user does not act on the trigger assembly, the first spring 26 is in a compressed state, accumulating elastic force. After acting on the trigger assembly, the elastic force of the first spring 26 is released, thereby forming a driving force on the ejection part 2; the first spring 26 extends into the groove formed by the inner tube wall 22 and the outer tube wall 21, which can limit the first spring 26 to maintain the relative position between the first spring 26 and the ejection part 2, so that the direction of the thrust received by the ejection part 2 remains in the preset direction; in addition, the movement direction of the ejection part 2 is restricted by the arrangement of the sliding groove 23 and the slide rail 11, further ensuring that the ejection part 2 can move in the preset direction after being stressed; in addition, the limiting groove 24 and the first limiting part 12 are in interference fit. When the two are fitted, the limiting groove 24 can form a clamping force on the first limiting part 12, thereby forming a certain degree of fixing effect on the ejection part 2.

[0068] As Figure 4 shown, as a preferred embodiment, the ejection part 2 is a cylindrical structure with an opening facing the inner bottom surface of the launch tube 1. The pulling mechanism 3 includes:

[0072] The second limiting part 33 is arranged on the bottom surface of the injection part 2, and a first protrusion is provided at the top end of the second limiting part 33, and the first protrusion abuts against the top end of the column head 321 to limit the movement of the column head 321;

[0073] The third limiting part 34, the base plate 31 is provided with a first through hole, the bottom surface of the injection part 2 is provided with a second through hole, the third limiting part 34 passes through the first through hole and the second through hole and enters the injection part 2, and a second protrusion is provided at the top end of the third limiting part 34, and the second protrusion abuts against the top end of the second limiting part 33 to limit the movement of the second limiting part 33; after the injection part 2 is launched, the blood glucose detector 5 is fixed on the human skin, and the third limiting part 34 is subjected to an impact force and thus slides in the first through hole and the second through hole, so that the third limiting part 34 is displaced from the second limiting part 33, and the top end of the second limiting part 33 is displaced after losing the abutment of the third limiting part 34, so that the column head 321 and the central column 32 move in the direction opposite to the injection direction under the action of the second spring, driving the base plate 31 and the mounting plate 4 to retract, so that the mounting plate 4 is separated from the blood glucose detector 5.

[0076] In this embodiment, through the arrangement of the third limiting part 34 that can slide in the first through hole and the second through hole, when the blood glucose detector 5 is attached to the human skin, an impact force that generates a reaction force on the third limiting part 34 is achieved, triggering the retraction mechanism 3 to retract the mounting plate 4, that is, it can ensure that after the blood glucose detector 5 has been installed, the mounting plate 4 is recycled, avoiding the influence on the installation of the blood glucose detector 5 caused by recycling the mounting plate 4; furthermore, through the arrangement of the guiding column 35, the moving direction of the base plate 31 is restricted, realizing the control of the retraction direction.

[0077] Such as Figures 5 - 7As shown, as a preferred embodiment, a groove is provided on the bottom surface of the base plate 31, and the shape of the mounting plate 4 matches the groove; a plurality of groups of combined groove bodies are provided on the side walls of the groove, each group of combined groove bodies includes a first groove body 311 and a second groove body 312 with different extension directions, and the first groove body 311 is connected to the corresponding second groove body 312; the side walls of the mounting plate 4 are provided with extension portions 42 whose number is the same as the number of combined groove bodies; during installation, each extension portion 42 on the mounting plate 4 is aligned with a first groove body 311 of a combined groove body, and the mounting plate 4 is moved along the extension direction of the first groove body 311, and when each extension portion 42 enters the corresponding second groove body 312, the mounting plate 4 is rotated so that the groove body wall of the second groove body 312 forms a limit on the extension portion 42, thereby fixing the mounting plate 4 on the bottom of the base plate 31.

[0078] The mounting plate 4 is provided with an arc groove 43 penetrating the mounting plate 4 , so that after the mounting plate 4 is mounted on the bottom of the base plate 31 , the third limiting portion 34 can extend through the arc groove 43 to below the mounting plate 4 .

[0079] In this embodiment, the number of groups of combined slot bodies can be 3 groups or other numbers; the first slot body 311 extends axially along the base plate 31, and the second slot body 312 extends along the central axis direction surrounding the base plate 31, and the extension direction of the first slot body 311 is perpendicular to that of the second slot body 312; through the design of the combined slot body and the extension portion 42, it is convenient for the user to firmly install the mounting plate 4 on the base plate 31, and it is also convenient to remove it, and due to the matching design of the groove and the mounting plate 4, the mounting plate 4 is embedded with the base plate 31 after being installed in the groove to form a whole, thereby improving the integrity of the two connecting parts; in addition, the third limiting portion 34 can extend to below the mounting plate 4 through the arc groove 43, which can ensure that it can retract when subjected to external impact to trigger the pullback mechanism 3.

[0080] like Figures 8 - 9 As shown, as a preferred embodiment, the ejection portion 2 includes a buckle 25, and the bottom surface of the launch tube 1 is provided with a buckle hole 13 that matches the buckle 25;

[0081] The trigger assembly includes a button 6 and a button 6 limiting assembly; a resistance portion 68 is provided on the button 6, and the button 6 is arranged on the outer bottom surface of the launching tube 1 so that the resistance portion 68 is positioned toward the clamping hole 13; when the ejecting part 2 slides to the inner bottom surface of the launching tube 1, the buckle 25 is clamped in the clamping hole 13 to fix the position of the ejecting part 2, and after pressure is applied to the button 6, the resistance portion 68 extends into the clamping hole 13, releasing the clamping connection between the buckle 25 and the clamping hole 13, so that the ejecting part 2 loses its fixing force and is pushed by the power part.

[0082] A fifth through hole 14 is provided on the bottom surface of the launch tube 1, and a third protrusion 61 is provided on the button 6;

[0083] The button 6 limiting assembly includes:

[0084] A transmission bar 62 is arranged on the outer bottom surface of the launch tube 1. A handle 621 is arranged at one end of the transmission bar 62. When an external force acts on the handle 621, the transmission bar 62 slides on the outer bottom surface of the launch tube 1.

[0085] A fourth limiting portion 63 is provided on the outer bottom surface of the launch tube 1 and is used to limit the transmission bar 62 to prevent the transmission bar 62 from being separated from the outer bottom surface of the launch tube 1;

[0086] The moving bar 64 is arranged on the outer bottom surface of the launch tube 1, one end of the moving bar 64 abuts against the other end of the transmission bar 62, and a fourth protrusion 641 is arranged on the moving bar 64, and the fourth protrusion 641 abuts against the third protrusion 61 to achieve the limit of the button 6; when the transmission bar 62 is moved by force, the moving bar 64 moves accordingly, and the fourth protrusion 641 is staggered with the third protrusion 61, thereby releasing the limit of the button 6;

[0087] A fifth limiting portion 65 is provided on the outer bottom surface of the launch tube 1 and is used to limit the moving bar 64 to prevent the moving bar 64 from being separated from the outer bottom surface of the launch tube 1;

When the moving bar 64 is moved by the transmission bar 62, the third spring 67 is compressed. When the force applied to the transmission bar 62 is removed, the force of the third spring 67 resets the moving bar 64, thereby re-limiting the button 6.

[0090] In the present embodiment, by the matching arrangement of the buckle 25 and the clamping hole 13, the ejection part 2 is firmly fixed to the inner bottom of the sending tube when the firing is not triggered; by the arrangement of the button 6 limiting assembly, when the user presses the button 6 to trigger the firing, the user needs to first release the limit of the button 6 by the button 6 limiting assembly, thereby avoiding the firing of the wrong firing caused by the user's mistaken touch; when the user acts on the handle 621, the transmission bar 62 slides on the outer bottom surface of the launching tube 1, and the moving bar 64 moves accordingly, and the fourth protrusion 641 is staggered with the third protrusion 61, thereby releasing the limit on the button 6, and the user presses the button 6 again, so that the contact part 68 extends into the clamping hole 13, and the clamping connection between the buckle 25 and the clamping hole 13 is released, so that the ejection part 2 loses the fixing force and is pushed by the power member; after the firing is completed, the action force of the third spring 67 resets the moving bar 64, and then limits the button 6 again, thereby avoiding the user's negligence and forgetting to limit the button 6 again.

[0098] In the present embodiment, since the detection head 51 of the blood glucose detector 5 is a soft head, it is difficult for it to pierce the human skin to detect the blood glucose of the human body. In the present embodiment, the detection head 51 is embedded in the slotted needle 41 (the detection head 51 is bent along the extension direction of the slotted needle 41 and then placed in the slot body of the slotted needle 41), so that the rigid slotted needle 41 pierces the human skin instead, thereby achieving the effect of sending the detection head 51 into the human skin, and the slotted needle 41 can be recovered together with the recovery of the installation disk 4, without the need for additional operations, and is highly convenient.

[0099] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
