Description

Technical Field

[0001] The utility model relates to the technical field of dynamic blood glucose meters, in particular to a dynamic blood glucose meter syringe assembly. Background Art

[0002] A continuous blood glucose meter (CGM) is a medical device that monitors blood sugar levels over extended periods of time. The device's principle is to insert the probe of the CGM module subcutaneously into the subject's skin, where it chemically reacts with glucose in the interstitial fluid beneath the skin, generating an electronic signal. The monitoring system's recorder receives this electrical signal from the probe at regular intervals, obtaining a monitoring value. These multiple values are then averaged and converted into a stored blood sugar value. This device offers the advantage of generating a continuous, all-day blood sugar record, providing warnings and alerts for high or low blood sugar levels, and allowing for continuous use over multiple days without affecting exercise, bathing, or other activities.

[0003] In the existing technology, a needle assist device and a dynamic blood glucose monitoring component are generally directly assembled for use, and the hard needle is directly set on the needle assist device. After the dynamic blood glucose monitoring component is installed on the tester's skin, the hard needle is located in the tester's skin. The hard needle needs to be picked up with the needle assist device to complete the action of pulling out the tester's body. Increasing the time the hard needle penetrates the tester's skin will bring more discomfort and pain. At the same time, the dynamic blood glucose meter is generally purchased and used by the tester himself, and he does not have the operating experience of medical staff. There is a risk of operational errors in the process of pulling out the hard needle, and even infection may occur. Therefore, there is an urgent need for a component that can realize the recovery of the hard needle to be integrated into the dynamic blood glucose meter. Utility Model Content

[0004] In order to overcome at least one of the defects described in the above-mentioned prior art, the present invention provides a dynamic blood glucose meter syringe assembly, which can solve the problem that the hard needle in the dynamic blood glucose meter needs to be picked up with the needle aid to be pulled out from the tester's skin, and there is a lack of a component that can cooperate with the needle aid to realize automatic recovery of the hard needle.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A continuous blood glucose meter syringe assembly, comprising:

[0007] A syringe, wherein an assembly cavity is provided in the syringe, a spring is provided on the side wall of the assembly cavity, and the spring can be bent into the assembly cavity by an external force of the assembly cavity, and a first limiter is provided in the assembly cavity;

[0008] a hard needle mounting member, the hard needle mounting member being slidably disposed in the assembly cavity and provided with a second limiting member;

[0009] A hard needle, wherein the hard needle is fixedly connected to the hard needle mounting member;

[0010] a hard needle recovery spring, the hard needle recovery spring being disposed in the assembly cavity, with one end of the hard needle recovery spring abutting against the first limiting member and the other end abutting against the second limiting member;

[0011] Among them, when the hard needle recovery spring is in a compressed and stored state, the spring sheet is bent toward the assembly cavity by the external force and abuts against the hard needle mounting part; when the hard needle recovery spring is in a released and reset state, the spring sheet is reset, and the abutment state with the hard needle mounting part is disengaged, and the hard needle recovery spring is reset.

[0012] By adopting the above scheme, the hard needle is fixedly connected to the hard needle mounting part, and a hard needle recovery spring is provided between the second limit part of the hard needle mounting part and the first limit part of the syringe. Before the hard needle is fired, the hard needle recovery spring is compressed, and the second limit part limits the hard needle recovery spring so that the hard needle recovery spring is in a compressed state. An external force is applied to the shrapnel through the needle assisting device to cause the shrapnel to elastically deform into the assembly cavity, and the hard needle mounting part that limits the hard needle recovery spring is limited. After the hard needle is fired, the needle assisting device releases the force on the shrapnel, and the shrapnel returns to its original state. The hard needle mounting part that limits the rebound of the hard needle recovery spring rebounds under the action of the hard needle recovery spring, driving the hard needle to move in a direction away from the tester's skin, thereby completing the automatic recovery of the hard needle. That is, by setting the syringe, hard needle mounting part and hard needle recovery spring of the dynamic blood glucose meter syringe assembly, the hard needle is automatically recovered, which greatly reduces the time the hard needle stays in the tester's skin, and solves the problems such as increased discomfort and pain of the tester caused by the increased time the hard needle stays in the skin, and reduces the possibility of operational errors caused by the removal of the hard needle, and even infection problems caused by the tester.

[0013] Furthermore, a first clamping piece is provided at one end of the syringe away from the hard needle launching direction for assembling the syringe.

[0014] By adopting the above solution, the first clamping member facilitates the installation of the syringe on the needle assisting device.

[0015] Furthermore, one end of the hard needle mounting member facing the hard needle launching direction is connected to a second clamping member, and the hard needle mounting member and the second clamping member are detachably connected.

[0016] By adopting the above scheme, the second clamping part can be clamped with the hard needle mounting part, so that the hard needle recovery spring always remains in a compressed state before use. After the dynamic blood glucose meter syringe assembly and the needle assist device are installed in place, the needle assist device compresses the spring piece. After the spring piece limits the hard needle mounting part, the second clamping part is removed, so that the hard needle recovery spring is in a state where the spring piece is reset and the hard needle recovery spring rebounds, which is convenient for the tester to use.

[0017] Furthermore, the second clamping part is a needle cover, the hard needle mounting part is provided with a first clamping structure, the needle cover is provided with a second clamping structure detachably connected to the first clamping structure, the first clamping structure and the second clamping structure are detachably connected, and the needle cover closes the hard needle extending out of the syringe.

[0018] By adopting the above solution, the needle shield is provided with a second clamping structure to facilitate the detachable connection to the first clamping structure of the hard needle mounting component, and the needle shield can seal the hard needle exposed outside the syringe to prevent the hard needle from being contaminated before injection.

[0019] Furthermore, the hard needle mounting component includes a needle seat and a needle clamp, the needle seat and the needle clamp are snap-connected, the hard needle is fixedly connected to the needle seat, and the second limiting component is provided on the needle clamp.

[0020] By adopting the above solution, the hard needle mounting part is composed of a needle seat and a needle clamp that are connected by a clip, which facilitates the design and production of the hard needle mounting part.

[0021] Furthermore, the end of the syringe located in the direction of emission of the hard needle is equipped with the dynamic blood glucose monitoring component, and the hard needle is arranged to pass through the dynamic blood glucose monitoring component.

[0022] Furthermore, the dynamic blood glucose monitoring component is provided with a fixed bracket facing away from the emission direction of the hard needle.

[0023] By adopting the above solution, the fixing bracket facilitates the assembly of the dynamic blood glucose meter syringe assembly and the needle assisting device.

[0024] Furthermore, one end of the hard needle mounting component facing the hard needle launching direction is connected to a second clamping component, and the fixing bracket is fixedly connected to the second clamping component.

[0025] By adopting the above solution, it is convenient for the tester to remove the connection restriction of the second clamping part on the hard needle mounting part when removing the fixing bracket.

[0026] Furthermore, the dynamic blood glucose monitoring component is provided with an adhesive layer, and the adhesive layer is laminated with an adhesive layer protective film.

[0027] By adopting the above solution, the adhesive layer facilitates the attachment of the dynamic blood glucose detection component to the tester's skin, and the adhesive layer protective film can prevent the adhesive layer from being contaminated before use, thereby ensuring the hygiene and stickiness of the adhesive layer.

[0028] Furthermore, the fixing bracket is connected to the adhesive layer protective film.

[0029] By adopting the above solution, it is convenient to remove the adhesive layer protective film at the same time when removing the fixed bracket, thereby reducing the operating steps of the tester.

[0030] In summary, the present invention provides a dynamic blood glucose meter syringe assembly with the following technical effects:

[0031] The hard needle is fixedly connected to the hard needle mounting part, and a hard needle recovery spring is provided between the second limit part of the hard needle mounting part and the first limit part of the syringe. Before the hard needle is fired, the hard needle recovery spring is compressed, and the second limit part limits the hard needle recovery spring so that the hard needle recovery spring is in a compressed state. An external force is applied to the shrapnel through the needle assist device to cause the shrapnel to elastically deform into the assembly cavity, thereby limiting the hard needle mounting part that limits the hard needle recovery spring. After the hard needle is fired, the needle assist device releases the force on the shrapnel, and the shrapnel returns to its original state. The hard needle mounting part that limits the rebound of the hard needle recovery spring rebounds under the action of the hard needle recovery spring, driving the hard needle to move in a direction away from the tester's skin, thereby completing the automatic recovery of the hard needle. That is, by setting the syringe, hard needle mounting part and hard needle recovery spring of the dynamic blood glucose meter syringe assembly, the hard needle is automatically recovered, which greatly reduces the time the hard needle stays in the tester's skin, and solves the problems such as increased discomfort and pain of the tester caused by the increased time the hard needle stays in the skin, and reduces the possibility of operational errors caused by the removal of the hard needle, and even infection problems caused by the tester.

DETAILED DESCRIPTION

[0042] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained with reference to specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0044] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0046] See Figure 1-Figure 3As shown, the utility model discloses a dynamic blood glucose meter syringe 1 assembly, including a syringe 1, a hard needle mounting part 2, a hard needle 3, and a hard needle recovery spring 4. An assembly chamber 11 is provided in the syringe 1, and a side wall of the assembly chamber 11 is provided with a spring piece 12. The spring piece 12 can be bent toward the assembly chamber 11 by the external force of the assembly chamber 11. A first limit piece 13 is provided in the assembly chamber 11, and the hard needle mounting part 2 is slidably arranged in the assembly chamber 11. The hard needle mounting part 2 is provided with a second limit piece 221. The hard needle 3 is fixedly connected to the hard needle mounting part 2. The hard needle recovery spring 4 is provided in the assembly chamber 11, and one end of the hard needle recovery spring 4 is against the first limit piece 13, and the other end is against the second limit piece 221. Among them, when the hard needle recovery spring 4 is in a compressed and stored state, the spring piece 12 is bent toward the assembly cavity 11 by the external force and abuts against the hard needle mounting part 2; when the hard needle recovery spring 4 is in a released and reset state, the spring piece 12 resets, disengages from the abutment state with the hard needle mounting part 2, and the hard needle recovery spring 4 resets.

[0047] Specifically, an assembly cavity 11 is provided in the syringe 1, and a spring piece 12 is provided on the side wall of the assembly cavity 11. The spring piece 12 can be affected by external components, especially when combined with the needle assisting device 9, and is elastically deformed into the assembly cavity 11 by the action of the needle assisting device 9. In this embodiment, the spring piece 12 is provided for the syringe 1 to set the assembly cavity 11 by digging a U-shaped through hole in the cylinder wall, and the remaining part integrated with the syringe 1 constitutes the spring piece 12. The spring piece 12 is provided in this way of digging a U-shaped through hole, which facilitates the assembly of the dynamic blood glucose meter syringe 1 assembly. On the basis of this structure, the outer surface of the spring piece 12 can be provided on the first protruding structure 121 as needed. When the spring piece 12 is provided with the first protruding structure 121, the needle assisting device 9 can more easily compress the spring piece 12 into the assembly cavity 11 at a larger angle, thereby facilitating the design of the needle assisting device 9. Correspondingly, a second protruding structure 122 can be optionally provided on the end of the inner surface of the spring piece 12 facing the hard needle mounting part 2. The second protruding structure 122 can provide sufficient force to limit the upward movement of the hard needle mounting part 2 when the spring piece 12 is bent at a small angle into the assembly cavity 11, thereby ensuring the stability of the spring piece 12 in limiting the position of the hard needle mounting part 2. It should be noted that the second protruding structure 122 extends into the assembly cavity 11 to a limited extent and will not affect the sliding of the hard needle mounting part 2 in the assembly cavity 11. In addition, in order to ensure that the force limiting the hard needle mounting part 2 is uniform, a plurality of spring pieces 12 can be arranged at equal intervals on the wall of the syringe 1 to balance the force of the contact between the hard needle mounting part 2 and the spring piece 12. A first limiting member 13 is provided in the assembly cavity 11 to resist the hard needle recovery spring 4. In this embodiment, the first limiting member 13 is integrally formed with the syringe 1. The needle mount 2 slides within the assembly cavity 11, and optimally, the first stopper 13 prevents the needle mount 2 from sliding out. The needle mount 2 is equipped with a second stopper 221. One end of the needle recovery spring 4 abuts against the first stopper 13, while the other end abuts against the second stopper 221. This allows the needle recovery spring 4 to be controlled by adjusting the relative position of the first stopper 13 and the second stopper 221. The needle 3 is fixedly mounted on the needle mount 2, ensuring that it moves with the movement of the needle mount 2.

[0048] The working principle of the above structure is:

[0049] Before the needle 3 is fired, the needle recovery spring 4 is compressed, and the second stopper 221 limits the needle recovery spring 4, placing it in a compressed state. The needle assist device 9 then applies an external force to the spring 12, causing it to elastically deform into the assembly cavity 11, thereby limiting the position of the needle mounting member 2 that was restraining the needle recovery spring 4. After the needle 3 is fired, the needle assist device 9 releases the force on the spring 12, causing it to return to its original state. The needle mounting member 2, which had been restraining the needle recovery spring 4 from rebounding, then rebounds under the force of the spring 4, driving the needle 3 away from the test subject's skin, thereby completing the automatic retraction of the needle 3. In other words, the automatic retraction of the needle 3 is achieved through the coordination of the syringe 1, the needle mounting member 2, and the needle recovery spring 4 in the continuous blood glucose meter syringe 1 assembly.

[0050] It should be noted that, for ease of understanding, the above description of the operating principle uses the needle-assist device 9 to illustrate the use of the continuous blood glucose meter syringe 1 assembly. During use, the tester can also use their hands to apply pressure to the spring 12, causing it to elastically deform into the assembly cavity 11, thereby limiting the position of the rigid needle mounting member 2. After the injection is completed, the hard needle 3 can still be automatically retracted by releasing the spring 12 with their fingers. Therefore, the effect of the needle-assist device 9 on the spring 12 is not a necessary technical feature.

[0051] See Figure 1-Figure 3 As shown, in some embodiments, a first clamping member 8 is provided at one end of the syringe 1 away from the firing direction of the hard needle 3 for assembling the syringe 1 .

[0052] Specifically, the first clamping member 8 can be a common clamping structure such as a groove or a protrusion. By providing a clamping structure that cooperates with the first clamping member 8 on the needle assisting device 9, the syringe 1 can be prevented from falling out after being assembled on the needle assisting device 9.

[0053] See Figure 1-Figure 4 As shown, in some embodiments, in order to reduce the number of operating steps during use by the tester, a second clamping member is connected to the end of the hard needle mounting member 2 facing the direction of firing of the hard needle 3. The hard needle mounting member 2 and the second clamping member are detachably connected. A specific usage scenario is that when the continuous blood glucose meter syringe 1 assembly leaves the factory, the hard needle mounting member 2 is slid in the direction of firing of the hard needle 3, so that the first limiting member 13 and the second limiting member 221 compress the hard needle recovery spring 4. The second clamping member clamps and fixes the hard needle mounting member 2 after the compression of the hard needle recovery spring 4, so that the hard needle recovery spring 4 remains in a compressed state before the detachable connection between the second clamping member and the hard needle mounting member 2 is released. In subsequent use, after the continuous blood glucose meter syringe 1 assembly and the needle assisting device 9 are installed in place, the needle assisting device 9 compresses the spring 12. After the spring 12 has limited the position of the hard needle mounting member 2, the second clamping member is removed, so that the hard needle recovery spring 4 is in a state where the spring 12 resets and the hard needle recovery spring 4 rebounds, making it easier for the tester to use.

[0054] See Figure 1-Figure 4 As shown, in this embodiment, in order to prevent the hard needle 3 from being contaminated before use, the second clamping member is a needle cover 5. The hard needle mounting member 2 is provided with a first clamping structure 211. The needle cover 5 is provided with a second clamping structure 51 detachably connected to the first clamping structure 211. The first clamping structure 211 and the second clamping structure 51 are detachably connected. The needle cover 5 seals the hard needle 3 extending out of the syringe 1. The needle cover 5 can seal the hard needle 3 exposed outside the syringe 1 to prevent the hard needle 3 from being contaminated before injection. The first clamping structure 211 and the second clamping structure 51 can be a threaded matching structure, a block and slot matching structure, etc. In this embodiment, the first clamping structure 211 and the second clamping structure 51 adopt a threaded matching structure to facilitate the removal of the needle cover 5.

[0055] See Figure 1-Figure 3 As shown, in this embodiment, in order to facilitate production and reduce production costs, the hard needle mounting part 2 includes a needle seat 21 and a needle clamp 22, the needle seat 21 and the needle clamp 22 are snap-connected, the hard needle 3 is fixedly connected to the needle seat 21, and the second limiting part 221 is provided on the needle clamp 22. The hard needle mounting part 2 is composed of the needle seat 21 and the needle clamp 22 being snap-connected, which facilitates the design and production of the hard needle mounting part 2.

[0056] See Figure 1-Figure 4 As shown, in some embodiments, in order to prevent the tester's operating steps from being further reduced, the dynamic blood glucose monitoring component 6 is arranged at the end of the syringe 1 facing the emission direction of the hard needle 3, and the dynamic blood glucose monitoring component 6 is shipped as a part of the dynamic blood glucose meter syringe 1 component to facilitate the tester's operation. Specifically, the end of the syringe 1 located in the emission direction of the hard needle 3 is equipped with a dynamic blood glucose monitoring component 6, and the hard needle 3 is arranged through the dynamic blood glucose monitoring component 6. Among them, the dynamic blood glucose monitoring component 6 has a soft needle 61. When the dynamic blood glucose monitoring component 6 is assembled, it is necessary to ensure that the hard needle 3 can drive the soft needle 61 to be injected into the body of the tester.

[0057] See Figure 4-Figure 5 As shown, in some embodiments, since part of the hard needle 3 is located outside the syringe 1, the force storage of the needle assisting device 9 often requires a pushing / pulling action to complete the force storage of the spring. In order to facilitate the force storage of the needle assisting device 9 after the dynamic blood glucose meter syringe 1 assembly is assembled, it will not be interfered with by the hard needle 3 during the pushing / pulling process. The dynamic blood glucose monitoring component 6 is provided with a fixed bracket 7 facing the emission direction away from the hard needle 3. Through the above structure, during use after the dynamic blood glucose meter syringe 1 assembly and the needle assisting device 9 are assembled, it will not be interfered with by the hard needle 3 outside the syringe 1, which is convenient for the tester to operate and use. When in use, the fixed bracket 7 can be removed from the dynamic blood glucose monitoring component 6.

[0058] See Figure 1-Figure 5As shown, in some embodiments, based on a structure in which the end of the rigid needle mounting member 2 facing the direction of ejection of the rigid needle 3 is detachably connected to the second clamping member, the fixed bracket 7 is fixedly connected to the second clamping member. During injection, when the fixed bracket 7 is removed, the second clamping member's connection restriction to the rigid needle mounting member 2 is also removed, reducing the number of steps required by the tester. Furthermore, the second clamping member and the solid bracket can be integrally molded.

[0059] See Figure 4-Figure 5 As shown, in some embodiments, to facilitate the stable adhesion of the dynamic blood glucose monitoring component 6 to the test subject's skin, the dynamic blood glucose monitoring component 6 is provided with an adhesive layer, and an adhesive layer protective film 62 is provided on the adhesive layer. The adhesive layer facilitates the adhesion of the dynamic blood glucose monitoring component to the test subject's skin. The adhesive layer protective film 62 can prevent contamination of the adhesive layer before use, ensuring the hygiene and adhesion of the adhesive layer. The adhesive layer protective film 62 can be made of a material that does not adhere to the adhesive layer, such as release paper.

[0060] See Figure 4-Figure 5 As shown, the fixing bracket 7 is further connected to the adhesive layer protective film 62. Specifically, the fixing bracket 7 and the adhesive layer protective film 62 can be connected by bonding or by inserting an anchoring structure such as a screw through the adhesive layer protective film 62 to complete the connection between the fixing bracket 7 and the adhesive layer protective film 62. In this embodiment, the adhesive layer protective film 62 integrally extends from a connecting ear 621, which is sleeved on the fixing bracket 7. When the fixing bracket 7 is removed, the adhesive layer protective film 62 is peeled off from the adhesive layer by the action of the connecting ear 621, thereby facilitating the removal of the adhesive layer protective film 62 at the same time as the fixing bracket 7, reducing the number of steps required by the tester.

[0061] The following will use a needle assist device 9 used in this embodiment to illustrate the working principle of the present utility model:

[0062] Ready to launch: See Figure 6 and Figure 7 As shown, the dynamic blood glucose meter syringe 1 assembly is assembled in the needle assisting device 9, and a sliding pressing part 91 is provided in the needle assisting device 9. The sliding pressing part 91 is slidably arranged in the needle assisting device 9. In the ready-to-fire state, the sliding pressing part 91 is in the position of the pressing shrapnel 12, and the pressing shrapnel 12 bends into the assembly cavity 11 to limit the displacement of the needle clamp 22. The needle clamp 22 is clamped and connected to the needle seat 21. The needle seat 21 is against the hard needle recovery spring 4 in the compressed state to limit the rebound of the hard needle recovery spring 4, release the detachable connection between the needle cover 5 and the needle seat 21, and remove the fixed bracket 7. Since the adhesive layer protective film 62 and the needle cover 5 are both connected to the fixed bracket 7, the adhesive layer protective film 62 and the needle cover 5 are removed at the same time during the process of removing the fixed bracket 7, completing the preparation for the ready-to-fire state.

[0063] Launch status: See Figure 8 As shown, the needle-assisting device 9 injects the hard needle 3 and the continuous blood glucose monitoring component 6 into the skin of the test subject, and the sliding pressing member 91 moves in a direction away from the direction of the hard needle 3. Figure 9 As shown, the sliding pressing member 91 releases the pressing on the spring 12, and the spring 12 returns to its original state. The needle seat 21 is acted upon by the hard needle recovery spring 4 to drive the needle clamp 22 and the hard needle 3 installed on the needle clamp 22 to move together in a direction away from the launching direction of the hard needle 3, thereby completing the automatic recovery of the hard needle 3.

[0064] Remove the dynamic blood glucose meter syringe 1 assembly still in the needle assisting device 9: release the connection between the first clamping part 8 and the needle assisting device 9, and the syringe 1 will drive the hard needle recovery spring 4, needle clamp 22, needle seat 21 and hard needle 3 to disengage from the needle assisting device 9, thereby facilitating the subsequent reuse of the needle assisting device 9.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
