[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0045] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.

[0046] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] In order to ensure the safety of use, some medical devices need to be used once to avoid repeated use causing infection to users and endangering their health. For example, diabetic patients can use analyte sensors to detect whether their glucose levels are within the safe range. The analyte sensors can extend their probes into the subcutaneous tissue to continuously detect the glucose level in the blood. In order to avoid cross infection caused by repeated contact with blood, they are generally used once. In order to reduce the cost of such disposable medical devices, disposable medical devices are generally connected to the power supply during production and will always remain powered on. When installing batteries in such disposable medical devices, the positive and negative electrodes of the batteries need to be welded and fixed to the circuit board first. For example, by welding the positive and negative electrodes of the button battery to the circuit board, the circuit board is powered on before the product is assembled. Therefore, before the assembly is completed, the disposable medical device starts to be powered on, resulting in a certain amount of power loss in the disposable medical device. It should be noted that such disposable products are often mass-produced during production, that is, after the batteries are welded in batches, the subsequent steps of product assembly will be carried out, which undoubtedly further increases the power loss. Moreover, the battery itself may be damaged when welding the positive and negative electrodes of the battery. Therefore, the existing battery connection method reduces the shelf life of the product, and there is also a certain yield loss in the battery welding process.

[0048] To this end, the embodiment of the present application provides a disposable medical device and a battery connection method thereof. After the disposable medical device is assembled, the shelf life of the product can be effectively extended. In addition, the medical device is easy to assemble, which can avoid operating errors by operators. There is no need to fix the button battery by welding or the like, which can avoid the loss of yield of button battery welding.

[0049] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] like Figure 1 and Figure 2As shown, a disposable medical device provided in an embodiment of the present application includes a first shell 10 , a second shell 20 , a circuit assembly 30 , a spring 40 and a button battery 50 .

[0051] The second housing 20 is connected to the first housing 10. The circuit assembly 30 is disposed on the first housing 10, and the circuit assembly 30 is provided with a connecting piece 32 and an electrical connector 33. The spring 40 is disposed on the second housing 20. The button battery 50 is provided with a plurality of electrode parts, and the button battery 50 is clamped in the spring 40, and at least one of the plurality of electrode parts is electrically connected to the spring. When the second housing 20 is connected to the first housing 10, at least one of the plurality of electrode parts is electrically connected to the connecting piece, and the spring 40 is electrically connected to the electrical connector 33.

[0052] It should be noted that the spring 40 , the connecting piece 32 and the electrical connector 33 of the present application are all made of conductive materials so that the circuit assembly 30 can be powered after the button battery 50 is electrically connected thereto.

[0053] It should be noted that one of the first shell 10 and the second shell 20 can be a base, and the other can be an upper cover, that is, the circuit assembly 30 of the present application can be first set on the base, the button battery 50 and the spring 40 can be first set on the upper cover, and then set on the base through the upper cover to complete the assembly of the disposable medical device; or, the circuit assembly 30 can also be first set on the upper cover, the button battery 50 and the spring 40 can also be first set on the base, and then set on the base through the upper cover to complete the assembly of the disposable medical device. Exemplarily, the first shell 10 is the base, and the second shell 20 is the upper cover.

[0054] It should be noted that at least two of the multiple electrode portions of the button battery 50 have different polarities, and the multiple electrode portions are separated by insulating materials. For example, the multiple electrode portions include a first electrode portion 51 and a second electrode portion 52, one of the first electrode portion 51 and the second electrode portion 52 is a positive electrode, and the other is a negative electrode. Exemplarily, the first electrode portion 51 is a negative electrode, and the second electrode portion 52 is a positive electrode.

[0055] It should be noted 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 first shell 10 and the second shell 20 are connected and assembled, the disposable medical device is equivalent to being completed and can be put on the market for sale. In the actual production assembly line, the first shell 10 with the circuit assembly 30 installed and the second shell 20 with the button battery 50 and the spring 40 installed are often assembled in batches. At this time, the circuit assembly 30 is still not powered on and will not cause power loss. After the first shell 10 and the second shell 20 are assembled, the circuit assembly 30 is powered on, and the production of the disposable medical device is completed.

[0056] It should be noted that since the disposable medical device is a disposable product, there is no need to set other switch structures, detachable structures, etc. In this way, the cost of the disposable medical device can be reduced and mass production can be facilitated. It is also for this reason that it is necessary to complete the power supply during assembly to facilitate subsequent use.

[0057] The disposable medical device of the embodiment of the present application, when assembled, can first install the button battery 50 in the spring 40 to fix it on the second shell 20, and then, when the second shell 20 and the first shell 10 are connected, the electrical connection between the button battery 50 and the connecting piece 32, and the electrical connection between the spring 40 and the electrical connector 33 can be realized, so that the button battery 50 can energize the circuit assembly 30. Therefore, the disposable medical device can complete the assembly of the disposable medical device in the last step of production assembly, and energize the internal electrical components at the same time as the assembly is completed. Compared with energizing the electrical components before the assembly is completed, the disposable medical device of the present application can reduce power loss during assembly, and after the assembly is completed, it can effectively extend the shelf life of the product, and the medical device is simple to assemble, which can avoid operator errors, and there is no need to fix the button battery 50 by welding or other methods, which can avoid the yield loss of the button battery 50 welding.

[0058] like Figure 1 , Figure 3 as well as Figure 4 As shown, in the embodiment of the present application, the connecting piece 32 is provided with a first elastic piece 321 extending away from the first shell 10, the first elastic piece 321 abuts against the button battery 50, and is electrically connected to at least one electrode portion of the plurality of electrode portions, for example, is electrically connected to the second electrode portion 52. When the button battery 50 abuts against the first elastic piece 321, the first elastic piece 321 is pressed downward toward the first shell 10 and undergoes elastic deformation, at which time, the first elastic piece 321 can abut against the electrode portion of the button battery 50 more closely, ensuring better electrical contact, so as to ensure the normal use of the disposable medical device after assembly.

[0059] Exemplarily, the connecting piece 32 has a connecting hole, one end of the first elastic piece 321 is fixedly connected to the side of the connecting hole, and the other end is a free end and extends in a direction away from the first shell 10, so that when the button battery 50 presses against the other end of the first elastic piece 321, the first elastic piece 321 can be pressed down and elastically deformed. In the specific production process, a U-shaped notch can be cut on the connecting piece 32, and the part surrounded by the U-shaped notch is bent toward one side to form the first elastic piece 321, so that welding is not required, and the structure of the first elastic piece 321 is firm and reliable.

[0060] Exemplarily, the free end of the first spring piece 321 has a supporting portion 322 that is bent and extended in a direction parallel to the contact surface of the button battery 50. In this way, when the first spring piece 321 contacts the button battery 50, it is actually the supporting portion 322 that contacts the button battery 50. Due to the above-mentioned arrangement, a better contact area between the supporting portion 322 and the button battery 50 can be ensured, and when electrically connected to the electrode portion of the button battery 50, an effective and reliable electrical connection between the two can be ensured.

[0061] like Figure 1 , Figure 3 as well as Figure 4 As shown, in the embodiment of the present application, the circuit assembly 30 includes a circuit board 31, the circuit board is provided with an avoidance gap 31a, the connecting piece 32 is provided in the avoidance gap 31a, and the button battery 50 is at least partially accommodated in the avoidance gap 31a. It should be noted that if the circuit board 31, the connecting piece 32 and the button battery 50 are arranged in a longitudinally stacked manner, it will obviously greatly increase the thickness of the disposable medical device, which is not conducive to the use of the disposable medical device. Providing the connecting piece 32 in the avoidance gap 31a can make full use of the lateral space of the disposable medical device, avoid the connecting piece 32 from occupying additional longitudinal space, so as to reduce the thickness of the disposable medical device and thin the entire device. Moreover, in the disposable medical device after assembly, the button battery 50 can also be accommodated in the avoidance gap 31a, which can further thin the entire device.

[0062] Exemplarily, the surface of the connecting piece 32 facing the first shell 10 is flush with the surface of the circuit board 31 facing the first shell 10. In this way, when the circuit assembly 30 is installed on the first shell 10, it can be ensured that the bottom surface of the circuit assembly 30 is flush as a whole, so that it can be stably installed on the first shell 10, and there is no need to occupy additional longitudinal space. It should be noted that the thickness of the circuit board 31 itself is thicker than that of the connecting piece 32. Therefore, after the connecting piece 32 is placed on the bottom side of the circuit board 31, there is still a part between the connecting piece 32 and the avoidance gap 31a that can accommodate the button battery 50, so as to reduce the thickness of the whole machine.

[0063] Exemplarily, the avoidance notch 31a is a circular avoidance notch. In this way, the button battery 50 can be adapted and placed in the avoidance notch 31a, and the circuit board 31 can be as large as possible to ensure the realization of the corresponding function. In addition, the connecting piece 32 is a circular connecting piece, so that when the electrode portion of the button battery 50 and the connecting piece 32 are electrically connected, it can be ensured that the two have sufficient contact area, so as to ensure a stable electrical connection between the button battery 50 and the connecting piece 32.

[0064] like Figure 3As shown, in the embodiment of the present application, the circuit board 31, the connecting piece 32 and the electrical connector 33 are electrically connected, so that after the spring 40 and the electrical connector 33 are electrically connected, the button battery 50 generates a loop passing through the circuit board 31 to supply power to the circuit assembly 30.

[0065] Exemplarily, a plurality of conductive sheets 311 are provided on the circuit board 31, and a plurality of fixed notches are provided on the peripheral side of the avoidance notch 31a. The plurality of conductive sheets 311 correspond to the plurality of fixed notches one by one. The conductive sheets 311 are bent downward to extend into the corresponding fixed notches, and then bent and extended toward the connecting sheet 32 ​​and connected, thereby realizing the electrical connection between the circuit board 31 and the connecting sheet 32. It can be understood that the plurality of conductive sheets 311 can be overlapped at the corresponding fixed notches, so that the stable setting of the connecting sheet 32 ​​can be ensured. In the present application, the plurality of conductive sheets 311 and the connecting sheet 32 ​​are integrally formed, so that the connecting sheet 32 ​​can be stably mounted on the circuit board 31 through the plurality of conductive sheets 311. For example, two conductive sheets 311 are provided, and two fixed notches are also provided, and the two conductive sheets 311 extend to the two fixed notches respectively.

[0066] In addition, the electrical connector 33 is directly disposed on the circuit board 31, so that when the spring 40 and the electrical connector 33 are in contact, the electrical connection between the two can be achieved, and the structure is simple and the connection is stable.

[0067] like Figure 2 , Figure 4 as well as Figure 5 As shown, in the embodiment of the present application, the spring sheet 40 is provided with an elastic notch 40a, and the spring sheet 40 is provided with compression pieces 41 bent toward the inside of the spring sheet 40 on both sides of the elastic notch 40a, and the button battery 50 is placed in the spring sheet 40, and the compression pieces 41 on both sides are pressed against the peripheral side of the button battery 50. In this way, when the button battery 50 is installed in the spring sheet 40, the spring sheet 40 can press against one side of the button battery 50 through the compression piece 41, and press the button battery 50 toward the spring sheet 40 to clamp the button battery 50 to prevent the button battery 50 from falling off. In this way, it is convenient to complete the assembly of the disposable medical device after the subsequent connection of the first shell 10 and the second shell 20. It can be understood that the spring sheet 40 is a semi-open annular structure. During the manufacturing process, the sheet structure can be bent to form the spring sheet 40, and the two ends of the sheet structure can be bent inward to form the compression pieces 41. The structure is simple and easy to manufacture. Of course, in other embodiments, the spring sheet 40 may also be a closed annular structure, and the button battery 50 is fixed by interference fitting the spring sheet 40 and the button battery 50 .

[0068] like Figure 2 , Figure 4 as well as Figure 5As shown, in the embodiment of the present application, a plurality of guide portions 42 extending outwardly in a direction away from the first housing 10 are provided on the side of the spring sheet 40 facing away from the first housing 10. When installing the button battery 50 in the spring sheet 40, the button battery 50 can be placed on the spring sheet 40 and pressed toward the inside of the spring sheet 40. The button battery 50 will be placed in the spring sheet 40 under the guidance of the plurality of guide portions 42. In this way, the installation is simplified and the installation efficiency is improved.

[0069] Exemplarily, the pressing sheet 41 is also provided with a guide portion 42, so that when the button battery 50 is placed on the spring sheet 40 and pressed toward the spring sheet 40, the button battery 50 will abut against the guide portion 42 on the pressing sheet 41, and under the pressure, the pressing sheet 41 will be stretched open until the button battery 50 is placed in the spring sheet 40, and the pressing sheet 41 will also abut against the surrounding side of the button battery 50. Therefore, when installing the button battery 50 in the spring sheet 40, it is only necessary to press the button battery 50 into the spring sheet 40 without moving the pressing sheet 41, and the installation is simple and convenient.

[0070] like Figure 2 , Figure 4 as well as Figure 5 As shown, in the embodiment of the present application, a connecting protrusion 43 is provided on the inner periphery of the spring sheet 40, and the connecting protrusion 43 abuts against the peripheral side of the button battery 50. The button battery 50 can be clamped in the spring sheet 40 through the connecting protrusion 43.

[0071] like Figure 2 , Figure 4 as well as Figure 5 As shown, in the embodiment of the present application, the peripheral side of the button battery 50 is provided with an electrode portion, for example, a first electrode portion 51 is provided, and when the connecting protrusion 43 is against the peripheral side of the button battery 50, the connecting protrusion 43 can be electrically connected to the electrode portion on the peripheral side of the button battery 50. In this embodiment, the electrode portion on the peripheral side of the button battery 50 and the spring 50 are electrically connected, and there is no need to make an electrical connection at the bottom of the button battery 50 toward the second shell 20, so there is no need to further set a conductive structure between the bottom of the button battery 50 and the second shell 20, so that the entire disposable medical device can be further thinned, which is beneficial to the use of the disposable medical device. Of course, in other embodiments, an electrode portion may be provided on the side of the button battery 50 facing the second shell 20, and the spring 40 may be provided with an electrode connecting portion, which is located at the bottom of the spring 40 facing the second shell 20. When the button battery 50 is installed in the spring 40, the electrode portion of the button battery 50 may contact and be electrically connected to the electrode connecting portion. For example, a spring may also be provided at the electrode connecting portion to ensure a stable electrical connection.

[0072] For example, the inner circumference of the spring 40 is provided with a plurality of connection protrusions 43, which are pressed against the circumference of the button battery 50 and are electrically connected to the electrode portion. The plurality of connection protrusions 43 can ensure that the button battery 50 is stably clamped in the spring 40 on the one hand, and can also ensure a stable electrical connection between the spring 40 and the button battery 50 on the other hand.

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

[0074] like Figure 2 , Figure 4 as well as Figure 5 As shown, in the embodiment of the present application, the connecting protrusion 43 and the peripheral side of the button battery 50 are connected in a cooperative manner. For example, a recess may be provided on the peripheral side of the button battery 50 to cooperate with the connecting protrusion 43. In this way, when installing the button battery 50, the installation orientation of the button battery 50 can be ensured, so that the button battery 50 can only be installed in the forward direction. For example, the second electrode portion 52 of the button battery 50 is arranged in a direction away from the second shell 20, so that when the first shell 10 and the second shell 20 are subsequently assembled and connected, the correct electrical connection can be ensured. Therefore, the structure arranged in this way can make the installation simpler, ensure that the button battery 50 can only be installed in the forward direction, and avoid operating errors by the operator. At the same time, it can also ensure that the button battery 50 can be stably installed in the shrapnel 40.

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

[0076] Exemplarily, one end of the second spring piece 45 is connected to the side of the spring piece 40 facing the second shell 20, and is extended in an S shape in the direction away from the second shell 20. The other end of the second spring piece 45 is a free end. When the other end of the second spring piece 45 abuts against the electrical connector 33, the S-shaped second spring piece 45 is compressed to undergo elastic deformation, thereby ensuring the abutting force of the other end of the second spring piece 45 on the electrical connector 33 to ensure a stable electrical connection between the two.

[0077] Exemplarily, the free end of the second spring piece 45 also extends in an arc shape toward the second shell 20, so that the contact portion of the second spring piece 45 and the electrical connector 33 is arc-shaped, to avoid damage to the second spring piece 45 and the electrical connector 33 when they are in contact, thereby ensuring good electrical contact.

[0078] like Figure 2 , Figure 5 as well as Figure 6 As shown, in the embodiment of the present application, the second housing 20 is provided with a clamping portion 21, and a plurality of clamping grooves 21a are provided on the inner side of the clamping portion 21, and a plurality of clamping hooks 44 are provided on the peripheral side of the spring sheet 40. The spring sheet 40 is placed in the clamping portion 21, and the plurality of clamping hooks 44 are clamped in the plurality of clamping grooves 21a. In this way, the spring sheet 40 can be firmly clamped in the clamping portion 21 by the plurality of clamping hooks 44, so as to ensure that the spring sheet 40 and the button battery 50 can be firmly installed on the second housing 20, so as to facilitate the subsequent assembly of the disposable medical device after the second housing 20 and the first housing 10 are connected.

[0079] In the embodiment of the present application, the hook 44 is an elastic hook 44, and the hook 44 is extended outward in a direction away from the second housing 20.

Under continuous pressing, the hook 44 will deform inward until the spring sheet 40 is installed, and the hook 44 returns and is placed in the slot 21a. The hook 44 thus provided can facilitate the installation of the spring sheet 40 on the one hand, and on the other hand, after the hook 44 is placed in the slot 21a, it is not easy to deform and detach, so that the spring sheet 40 can be firmly installed on the second housing 20. In the specific production process, a U-shaped notch can be cut on the spring sheet 40, and the part surrounded by the U-shaped notch can be bent toward one side to form the hook 44. In this way, welding is not required, and the installation of the spring sheet 40 is firm and reliable.

[0080] Exemplarily, the clamping portion 21 is an annular clamping portion, and the spring 40 is adapted to fit in the clamping portion 21 to ensure the stable installation of the spring 40. In addition, the clamping portion 21 is provided with openings at the elastic notch 40a of the spring 40 and the compression pieces 41 on both sides, so that the compression pieces 41 can compress the button battery 50 by deformation.

[0081] Exemplarily, the locking portion 21 is provided with a notch to allow the second elastic piece 45 to extend from the locking portion 21 , thereby facilitating the connection between the second elastic piece 45 and the electrical connector 33 .

[0082] In the embodiment of the present application, the spring 40 is a structure formed in one piece with a conductive material. On the one hand, it can ensure its structural strength, and on the other hand, it can also ensure stable electrical connection. Exemplarily, the spring 40 is a copper spring.

[0085] like Figures 6 to 8 As shown, in this embodiment, a step groove 10b is provided on the peripheral side of the first mounting groove 10a, and the second shell 20 is provided with a step protrusion 22. When the second shell 20 is connected to the first shell 10, the step protrusion 22 is embedded in the step groove 10b to achieve a stable connection and installation of the second shell 20 and the first shell 10.

[0086] like Figure 1 , Figure 2 as well as Figure 8 As shown, in an embodiment of the present application, the disposable medical device includes a biological analyte sensor. The biological analyte sensor can be used to detect the analyte level in an organism, and then to evaluate its health. For example, the biological analyte sensor is a glucose sensor, which can be used to detect the glucose level in the human body to monitor the health of the human body in real time.

[0087] In some embodiments, the circuit assembly 30 further includes an analyte sensor component 34, which includes a tail portion and a marking portion. The tail portion extends through the through hole of the first housing 10 to be used as a subcutaneous tissue of a human body or other organisms to measure the level of the analyte, and the marking portion is connected to the circuit board 31 through a plurality of electrical contacts. In this embodiment, the analyte sensor component 34 and the button battery 50 are arranged in parallel along the lateral direction, so that the longitudinal space can be avoided to reduce the thickness of the whole machine. After the circuit board 31 is powered on by the button battery 50, the analyte sensor component 34 can be powered so that the corresponding analysis and measurement can be performed when the biological analyte sensor is used.

[0088] In some embodiments, the circuit assembly 30 further includes a communication component disposed on the circuit board 31, so as to transmit the measured information to other devices, for example, to a mobile phone so as to intuitively know the level of the analyte. Exemplarily, the communication component includes a Bluetooth module.
