[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0044] It should be noted that all directional indications, such as up, down, left, right, front, back, etc., in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0045] It should also be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or can have a middle element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or can be indirectly connected to the other element through a middle element.

[0046] In addition, the descriptions involving "first", "second", etc. in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0047] In order to ensure the safety of use of part of medical devices, it is required to be used once to avoid repeated use to cause infection to the user and harm the health of the user. For example, a diabetic patient can detect whether the glucose level of the diabetic patient is within a safe range through an analyte sensor, and the analyte sensor can detect the glucose level in the blood continuously by extending a stylus thereof into subcutaneous tissue, in order to avoid repeated contact with blood to cause cross infection, and the analyte sensor is generally used once. In order to reduce the cost of such a disposable medical device, the disposable medical device is generally connected to a power supply during production and is always powered on. When the battery of such a disposable medical device is installed, the positive and negative poles of the battery need to be welded and fixed to a circuit board, for example, by welding the positive and negative poles of a button battery to the circuit board, which causes the circuit board to be connected to the power supply before the product is completely assembled. Therefore, the disposable medical device starts to run with power on before the assembly is completed, which causes a certain power loss of the disposable medical device. It should be noted that such a disposable product is often produced in batches, that is, after the battery is welded in batches, subsequent product assembly steps are performed, which undoubtedly further increases the power loss. In addition, welding the positive and negative poles of the battery can also cause loss of the battery itself. Therefore, the existing battery connection method reduces the shelf time of the product, and the battery welding process also has a certain yield loss.

[0048] Therefore, the embodiments of the present application provide a disposable medical device and a battery connection method thereof, which can effectively prolong the shelf time of the product after the assembly of the disposable medical device is completed, and the medical device is simple to assemble, can avoid operation errors of workers, and does not need to be fixed by welding or the like. Button battery, which can avoid the yield loss of button battery welding.

[0049] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0050] As Figure 1 and Figure 2As shown, the disposable medical device provided by the embodiment of the present application comprises a first shell 10, a second shell 20, a circuit assembly 30, a spring sheet 40 and a button cell 50.

[0051] The second shell 20 is connected with the first shell 10. The circuit assembly 30 is arranged in the first shell 10, and the circuit assembly 30 is provided with a connecting sheet 32 and an electrical connecting piece 33. The spring sheet 40 is arranged in the second shell 20. The button cell 50 is provided with a plurality of electrode parts, the button cell 50 is clamped in the spring sheet 40, and at least one electrode part of the plurality of electrode parts is electrically connected with the spring sheet. When the second shell 20 is connected with the first shell 10, at least one electrode part of the plurality of electrode parts is electrically connected with the connecting sheet, and the spring sheet 40 is electrically connected with the electrical connecting piece 33.

[0052] It should be understood that the spring sheet 40, the connecting sheet 32 and the electrical connecting piece 33 of the present application all have a material capable of conducting electricity, so as to enable the circuit assembly 30 to be powered after the button cell 50 is electrically connected.

[0053] It should be understood that one of the first shell 10 and the second shell 20 can be a base, and the other can be a cover, that is, the circuit assembly 30 of the present application can be arranged on the base first, and the button cell 50 and the spring sheet 40 can be arranged on the cover first, and the cover is arranged on the base to complete the assembly of the disposable medical device; or the circuit assembly 30 can be arranged on the cover first, and the button cell 50 and the spring sheet 40 can be arranged on the base first, and the cover is arranged on the base to complete the assembly of the disposable medical device. Exemplarily, the first shell 10 is the base, and the second shell 20 is the cover.

[0054] It should be understood that at least two electrode parts of the button cell 50 have different polarities, and the plurality of electrode parts are separated by an insulating material. For example, the plurality of electrode parts comprise a first electrode part 51 and a second electrode part 52, one of the first electrode part 51 and the second electrode part 52 is a positive electrode, and the other is a negative electrode. Exemplarily, the first electrode part 51 is a negative electrode, and the second electrode part 52 is a positive electrode.

[0055] It should be understood that the assembly of the first shell 10 and the second shell 20 is the last step of the product assembly line, that is, after the assembly of the first shell 10 and the second shell 20 is completed, the disposable medical device is equivalent to being completed, and can be sold. In the actual production assembly line, the first shell 10 provided with the circuit assembly 30 and the second shell 20 provided with the button cell 50 and the spring sheet 40 are often assembled in batches at first, at this time, the circuit assembly 30 is still in a non-powered state and will not cause power loss, until the first shell 10 and the second shell 20 are assembled, the circuit assembly 30 is powered, and the production of the disposable medical device is completed.

[0056] It's important to understand that because this disposable medical device is a single-use product, there's no need for additional switching or detachable mechanisms. This reduces the cost of the device and facilitates mass production. Therefore, it needs to be powered on during assembly for convenient use.

[0057] In this embodiment of the disposable medical device, during assembly, the button battery 50 can be first installed inside the spring contact 40 to fix it to the second housing 20. Then, when the second housing 20 and the first housing 10 are connected, the button battery 50 and the connecting piece 32 can be electrically connected, and the spring contact 40 and the electrical connector 33 can be electrically connected, thus enabling the button battery 50 to power the circuit assembly 30. Therefore, this disposable medical device can be assembled in the final step of production assembly, and the internal electrical components can be powered at the same time as the assembly is completed. Compared to powering the electrical components before assembly is completed, the disposable medical device of this application can reduce power consumption during assembly, and can effectively extend the shelf life of the product after assembly. Furthermore, the medical device is easy to assemble, can avoid operator errors, and does not require welding or other methods to fix the button battery 50, thus avoiding yield loss due to button battery welding.

[0058] like Figure 1 , Figure 3 as well as Figure 4 As shown in this embodiment, the connecting piece 32 is provided with a first spring piece 321 extending away from the first housing 10. The first spring piece 321 abuts against the button battery 50 and is electrically connected to at least one of the plurality of electrode portions, for example, it is electrically connected to the second electrode portion 52. When the button battery 50 abuts against the first spring piece 321, the first spring piece 321 will press down toward the first housing 10 and undergo elastic deformation. At this time, the first spring piece 321 can abut against the electrode portion of the button battery 50 more tightly, ensuring better electrical contact and ensuring the normal use of the disposable medical device after assembly.

[0059] For example, the connecting piece 32 has a connecting hole, one end of the first spring piece 321 is fixed to the side of the connecting hole, and the other end is a free end, extending in a direction away from the first housing 10, so that when the button battery 50 presses against the other end of the first spring piece 321, the first spring piece 321 can be pressed down and elastically deformed. In the specific manufacturing process, a U-shaped notch can be cut on the connecting piece 32, and the part surrounded by the U-shaped notch can be bent to one side to form the first spring piece 321. In this way, welding is not required, and the structure of the first spring piece 321 is firm and reliable.

[0060] Exemplarily, the free end of the first elastic sheet 321 has a contact portion 322 which is bent and extends towards the direction parallel to the contact surface of the button cell 50. Thus, when the first elastic sheet 321 contacts the button cell 50, it is actually the contact portion 322 that contacts the button cell 50. Due to the above arrangement, the preferable contact area between the contact portion 322 and the button cell 50 can be ensured, and when the electrode portion of the button cell 50 is electrically connected with the first elastic sheet 321, the effective and reliable electrical connection between the button cell 50 and the first elastic sheet 321 can be ensured.

[0061] As shown in Figure 1 , Figure 3 and Figure 4 , in the embodiment of the present application, the circuit assembly 30 comprises a circuit board 31, the circuit board 31 is provided with a relief gap 31a, the connecting sheet 32 is arranged at the relief gap 31a, and the button cell 50 is at least partially accommodated in the relief gap 31a. It should be noted that if the circuit board 31, the connecting sheet 32 and the button cell 50 are arranged in a longitudinal stack, the thickness of the disposable medical device will be greatly increased, which is not conducive to the use of the disposable medical device. By arranging the connecting sheet 32 at the relief gap 31a, the transverse space of the disposable medical device can be fully utilized, the additional longitudinal space occupied by the connecting sheet 32 can be avoided, the thickness of the disposable medical device can be reduced, and the whole machine can be thinned. Moreover, after assembly, the button cell 50 can also be accommodated in the relief gap 31a, and the whole machine can be further thinned.

[0062] Exemplarily, the surface of the connecting sheet 32 towards the first shell 10 is flush with the surface of the circuit board 31 towards the first shell 10. Thus, when the circuit assembly 30 is installed in the first shell 10, the bottom surface of the circuit assembly 30 can be ensured to be flush as a whole, so as to be stably installed on the first shell 10, and no additional longitudinal space is needed. It should be noted that the thickness of the circuit board 31 itself is thicker than the thickness of the connecting sheet 32. Therefore, after the connecting sheet 32 is arranged on the bottom side of the circuit board 31, there is still a part between the connecting sheet 32 and the relief gap 31a which can accommodate the button cell 50, so as to reduce the thickness of the whole machine.

[0063] Exemplarily, the relief gap 31a is a circular relief gap. In this way, the button cell 50 can be adapted and arranged in the relief gap 31a, and the circuit board 31 can be ensured to be as large as possible to ensure the realization of the corresponding functions. In addition, the connecting sheet 32 is a circular connecting sheet. Thus, when the electrode portion of the button cell 50 is electrically connected with the connecting sheet 32, the contact area between the two can be ensured to be sufficient, so as to ensure the stable electrical connection between the button cell 50 and the connecting sheet 32.

[0064] As shown in Figure 3As shown, in the embodiment of the present application, the circuit board 31 and the connecting piece 32 and the electrical connecting piece 33 are electrically connected, so that after the elastic piece 40 and the electrical connecting piece 33 are electrically connected, the loop generated by the button cell 50 passes through the circuit board 31, so as to supply power to the circuit assembly 30.

[0065] As shown, the circuit board 31 is provided with a plurality of conductive pieces 311, and the circumferential side of the avoiding gap 31a is provided with a plurality of fixing gaps, the plurality of conductive pieces 311 and the plurality of fixing gaps correspond to each other, the conductive piece 311 is bent downward to extend into the corresponding fixing gap, and then bent and extends towards the connecting piece 32 and is connected, so as to realize the electrical connection between the circuit board 31 and the connecting piece 32. It can be understood that the plurality of conductive pieces 311 can be lapped at the corresponding fixing gap, so as to ensure the stable arrangement of the connecting piece 32. In the present application, the plurality of conductive pieces 311 and the connecting piece 32 are integrally formed, so that the connecting piece 32 can be stably arranged on the circuit board 31 through the plurality of conductive pieces 311. For example, the conductive piece 311 is provided with two, and the fixing gap is also provided with two, and the two conductive pieces 311 extend to the two fixing gaps respectively.

[0066] In addition, the electrical connecting piece 33 is directly arranged on the circuit board 31, so that when the elastic piece 40 and the electrical connecting piece 33 are in contact, the electrical connection between the two can be realized, the structure is simple and the connection is stable. As shown, the electrical connecting piece 33 is an electrical contact.

[0067] As shown in Figure 2 , Figure 4 and Figure 5 , in the embodiment of the present application, the elastic piece 40 is provided with an elastic gap 40a, and the elastic piece 40 is provided with a pressing piece 41 which is bent inwardly towards the elastic piece 40 on both sides of the elastic gap 40a, and the button cell 50 is arranged in the elastic piece 40, and the pressing pieces 41 on both sides abut against the circumferential side of the button cell 50. In this way, when the button cell 50 is installed in the elastic piece 40, the elastic piece 40 can abut against one side of the button cell 50 through the pressing piece 41, and press the button cell 50 inwardly towards the elastic piece 40, so as to clamp the button cell 50, so as to avoid the button cell 50 from falling off, so that after the first shell 10 and the second shell 20 are connected, the assembly of the disposable medical instrument can be completed. It can be understood that the elastic piece 40 is a semi-open ring structure, and when it is made, a sheet structure can be bent to form the elastic piece 40, and the two ends of the sheet structure can be bent inwardly to form the pressing piece 41, which is simple and convenient to manufacture. Of course, in other embodiments, the elastic piece 40 can also be a closed ring structure, and the button cell 50 is fixed by interference fit with the elastic piece 40.

[0068] As shown in Figure 2 , Figure 4 and Figure 5As shown, in the embodiment of the present application, the plurality of guiding portions 42 are arranged on the side of the elastic sheet 40 away from the first shell 10 and extend outward in the direction away from the first shell 10. When the button cell 50 is installed in the elastic sheet 40, the button cell 50 can be placed on the elastic sheet 40 and pressed into the elastic sheet 40. The button cell 50 is guided by the plurality of guiding portions 42 and placed in the elastic sheet 40. In this way, the installation is simplified and the installation efficiency is improved.

[0069] As shown, the guiding portions 42 are also arranged on the pressing sheet 41. When the button cell 50 is placed on the elastic sheet 40 and pressed into the elastic sheet 40, the button cell 50 abuts against the guiding portions 42 on the pressing sheet 41. The pressing sheet 41 is opened under the pressing of the button cell 50 until the button cell 50 is placed in the elastic sheet 40. At this time, the pressing sheet 41 also abuts against the side of the button cell 50. Therefore, when the button cell 50 is installed in the elastic sheet 40, the button cell 50 only needs to be pressed into the elastic sheet 40, and the pressing sheet 41 does not need to be moved. The installation is simple and convenient.

[0070] As shown in Figure 2 , Figure 4 and Figure 5 , in the embodiment of the present application, the inner periphery of the elastic sheet 40 is provided with a connecting protrusion 43, and the connecting protrusion 43 abuts against the side of the button cell 50. The button cell 50 can be clamped in the elastic sheet 40 by the connecting protrusion 43.

[0071] As shown in Figure 2 , Figure 4 and Figure 5 , in the embodiment of the present application, the side of the button cell 50 is provided with an electrode portion, for example, a first electrode portion 51. When the connecting protrusion 43 abuts against the side of the button cell 50, the connecting protrusion 43 can be electrically connected with the electrode portion on the side of the button cell 50. In this embodiment, the electrode portion on the side of the button cell 50 is electrically connected with the elastic sheet 40, and the button cell 50 does not need to be electrically connected with the bottom of the second shell 20. Therefore, the conductive structure does not need to be further arranged between the bottom of the button cell 50 and the second shell 20. In this way, the whole machine of the disposable medical instrument can be further thinned, which is beneficial to the use of the disposable medical instrument. Of course, in other embodiments, the electrode portion can be arranged on the side of the button cell 50 facing the second shell 20, and the elastic sheet 40 is provided with an electrode connecting portion located on the bottom of the elastic sheet 40 facing the second shell 20. When the button cell 50 is installed in the elastic sheet 40, the electrode portion of the button cell 50 can be in contact with and electrically connected with the electrode connecting portion. For example, the electrode connecting portion can also be arranged on the elastic sheet to ensure stable electrical connection.

[0072] Exemplarily, the inner periphery of the elastic sheet 40 is provided with a plurality of connecting protrusions 43, which abut against the periphery of the button cell 50 and are electrically connected with the electrode part. Through the plurality of connecting protrusions 43, on the one hand, the button cell 50 can be stably clamped in the elastic sheet 40, and on the other hand, the stable electrical connection between the elastic sheet 40 and the button cell 50 can be ensured.

[0073] Exemplarily, the connecting protrusions 43 are located on the opposite side of the elastic notch 40a. In this way, under the abutting of the pressing sheet 41, the stable contact between the button cell 50 and the connecting protrusions 43 can be further ensured. For example, three connecting protrusions 43 are provided, one of which is directly opposite the elastic notch 40a, and the other two are located on the two sides, respectively.

[0074] As shown in Figure 2 , Figure 4 and Figure 5 , in the embodiment of the present application, the connecting protrusions 43 are connected with the periphery of the button cell 50. For example, the periphery of the button cell 50 can be provided with a notch to connect with the connecting protrusions 43. In this way, when the button cell 50 is installed, the installation direction of the button cell 50 can be ensured, so that the button cell 50 can only be installed in the correct direction, for example, the second electrode part 52 of the button cell 50 is arranged in the direction away from the second shell 20, so that when the first shell 10 and the second shell 20 are assembled and connected subsequently, the correct electrical connection can be ensured. Therefore, the structure arranged in this way can make the installation simpler, ensure that the button cell 50 can only be installed in the correct direction, and avoid the operation errors of the operators. At the same time, it can also ensure that the button cell 50 can be stably installed in the elastic sheet 40.

[0075] As shown in Figure 1 , 2 and Figure 4 , in the embodiment of the present application, the elastic sheet 40 is provided with a second elastic sheet 45 extending away from the second shell 20, which abuts against the electrical connecting piece 33. When the second shell 20 and the first shell 10 are connected, the second elastic sheet 45 will abut against the electrical connecting piece 33 and elastically deform under the abutting pressure, at this time, the second elastic sheet 45 can abut more closely against the electrical connecting piece 33, to ensure better electrical contact, so as to ensure the normal use of the disposable medical device after the assembly is completed.

[0076] Exemplarily, one end of the second elastic sheet 45 is connected to the side of the elastic sheet 40 facing the second shell 20 and is arranged in an S-shaped extending manner away from the second shell 20, and the other end of the second elastic sheet 45 is a free end. When the other end of the second elastic sheet 45 abuts against the electrical connecting piece 33, the S-shaped second elastic sheet 45 will be compressed to elastically deform, so as to ensure the abutting force of the other end of the second elastic sheet 45 against the electrical connecting piece 33, to ensure the stable electrical connection between the two.

[0077] Exemplarily, the free end of the second elastic sheet 45 also extends arcuately towards the second shell 20, so that the part where the second elastic sheet 45 and the electrical connecting member 33 contact is arcuate, to avoid damage to the second elastic sheet 45 and the electrical connecting member 33 when they are pressed against each other, and to ensure good electrical contact.
