Description

Medical device active components and medical devices Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical device movable component and a medical device. Background Art

[0002] Chinese patent application number CN204233135U discloses a portable continuous blood glucose meter, as shown in Figure 1. The device comprises a main unit and a probe assembly. The main unit includes a housing M11 with a probe mounting position M12. The probe mounting position M12 may be formed by a piston sleeve extending through the main unit housing M11, with metal contacts M13 located on either side of the inner wall of the piston sleeve. Accordingly, the probe assembly may include a piston housing M21 that mates with the piston sleeve.

[0003] The above-mentioned existing portable continuous blood glucose meter, whose housing M11 and piston housing M21 constitute a support member for carrying the probe assembly, utilizes the matching relationship between the piston sleeve of the housing M11 and the piston housing M21 to drive the electrode needle of the probe assembly to move in a direction perpendicular to the skin surface. Specifically, the electrode needle is fixedly mounted on the piston housing M21. When the piston housing M21 slides along the piston sleeve of the housing M11, it will drive the electrode needle to slide along the piston sleeve until the electrode needle extends out of the piston sleeve and is vertically inserted into the skin to a set depth. When the electrode needle is not extended, the piston sleeve and the piston housing M21 need to partially overlap to ensure that the two can form the required guiding matching relationship in the initial state. At the same time, the piston sleeve also needs to reserve the length space required for the extension stroke of the electrode needle. As a result, the thickness of this support member and the blood glucose meter is relatively thick (usually about 11 mm), that is, the size of the support member and the blood glucose meter in the direction perpendicular to the skin is large and the weight is also heavy. As a result, when the user uses the blood glucose meter and the support member, it is easy to scratch against clothing, etc., resulting in a significant foreign body sensation and a poor user experience. In addition, this method of extending the electrode needle based on the sliding of the piston housing M21 in the piston sleeve is also prone to jamming.

[0004] Therefore, it is necessary to develop a movable part and a monitoring device with a thinner thickness. Summary of the Invention

[0005] The object of the present invention is to provide a medical device movable component and a medical device with a smaller thickness.

[0006] In the first aspect, the present invention provides a movable component of a medical device, including a support member body, the support member body including a first support member, a second support member, a first connecting component and a second connecting component, the first side of the first support member is movably connected to the second support member through the first connecting component, the second side of the first support member is movably connected to the second support member through the second connecting component, the first connecting component can guide the first support member to move relative to the second support member along a first plane, the second connecting component can guide the first support member to move relative to the second support member along a second plane, the first plane intersects with the second plane and forms an intersection line, and the intersection line is perpendicular to the mounting surface.

[0007] The beneficial effects of the medical device movable component of the present invention are as follows: the medical device movable component is based on the first side of the first support being movably connected to the second support through the first connecting component, and the second side of the first support being movably connected to the second support through the second connecting component. The first connecting component can guide the first support to move relative to the second support along the first plane, and the second connecting component can guide the first support to move relative to the second support along the second plane. The first plane and the second plane intersect to form an intersection line, and the intersection line is perpendicular to the mounting surface, so that the first support can only move relative to the second support along the intersection line perpendicular to the mounting surface, that is, the surface where the first and second support members are located can only move along the direction of the intersection line under the action of force; in this way, the needle device, etc. can be installed on the first support member. When in use, the second support member is fixed on the human skin, and the surface of the human skin is the mounting surface. Pressing any point of the first support member will cause the first support member to move simultaneously The needle device moves together toward the human skin, and the first support member and the needle device can only move in a direction perpendicular to the skin surface, thereby ensuring that the needle of the needle device can be vertically inserted into the skin to complete corresponding testing or injection needs; and this structural design realizes the movable connection between the first support member and the second support member based on the first connecting component and the second connecting component, and guides the first support member to move only in a direction perpendicular to the mounting surface relative to the second support member based on the first connecting component and the second connecting component. Compared with the prior art that uses the sliding contact between the piston and the piston sleeve to guide the corresponding components to move in a direction perpendicular to the skin, the overall thickness of the medical device movable component and the medical device with the medical device movable component can be thinner and the overall weight is lighter, avoiding easy scratches with worn clothes during use, reducing the user's foreign body sensation, and improving the user experience. At the same time, this structural design is simpler and has lower cost.

[0008] Preferably, the first connecting assembly includes a first connecting plate and a second connecting plate, one end of the first connecting plate being connected to a side edge of the first support member, the other end of the first connecting plate being connected to one end of the second connecting plate, and the other end of the second connecting plate being connected to the second support member. Angle A between the first and second connecting plates is variable, as is angle B between the first connecting plate and the first support member, and angle C between the second connecting plate and the second support member. This connection structure, based on the variable angle feature, ensures that the first support member can smoothly move in a set direction relative to the second support member while achieving the corresponding position limiting function for the first support member.

[0009] Preferably, the first connecting assembly further comprises a first connecting portion, a middle connecting portion, and a second connecting portion, wherein the first connecting plate is connected to the first support member via the first connecting portion, the first connecting plate is connected to the second connecting plate via the middle connecting portion, and the second connecting plate is connected to the second support member via the second connecting portion, and the first connecting portion, the middle connecting portion, and the second connecting portion are all capable of bending. Due to the first connecting portion, the middle connecting portion, and the second connecting portion being capable of bending, the angle A between the first connecting plate and the second connecting plate, the angle B between the first connecting plate and the first support member, and the angle C between the second connecting plate and the second support member can be varied.

[0010] Preferably, the first connecting plate, first support member, second connecting plate, second support member, first connecting portion, middle connecting portion, and second connecting portion are made of plastic, rubber, paper, metal, or a composite material, and the thickness and / or strength of the first connecting portion, middle connecting portion, and second connecting portion are less than the thickness and / or strength of the first connecting plate, first support member, second connecting plate, and second support member. This material design allows the first connecting plate, second connecting plate, first support member, and second support member to maintain a predetermined shape, while the first connecting portion, middle connecting portion, and second connecting portion can have the desired bending deformation capability.

[0011] Preferably, the structure of the second connecting component is the same as that of the first connecting component.

[0012] Preferably, the first connecting portion is a solid line structure, a dotted line structure, or a dotted structure; the middle connecting portion is a solid line structure, a dotted line structure, or a dotted structure; the second connecting portion is a solid line structure, a dotted line structure, or a dotted structure.

[0013] Preferably, the first connecting plate is hinged to the first support member via a pin, the first connecting plate is hinged to the second connecting plate via a pin, and the second connecting plate is hinged to the second support member via a pin. This structural design allows for variable angles A between the first and second connecting plates, B between the first connecting plate and the first support member, and C between the second connecting plate and the second support member; thereby enabling the first support member to move relative to the second support member while simultaneously restricting movement of the first support member relative to the second support member in a set direction.

[0014] Preferably, the first support member, the second support member, the first connecting assembly, and the second connecting assembly are integrally formed. This structural design allows the support member body to be quickly manufactured without requiring any assembly steps, which not only saves assembly steps and reduces costs, but most importantly, avoids assembly errors caused by the assembly process and improves the overall machining accuracy of the support member.

[0015] Preferably, a transition piece is provided at the gap between the first connecting assembly and the second connecting assembly.

[0016] Preferably, the third side of the first support member is movably connected to the second support member via a third connecting assembly, and the fourth side of the first support member is movably connected to the second support member via a fourth connecting assembly. The first side and the second side of the first support member are adjacent to each other; the first side and the third side of the first support member are positioned correspondingly, and the second side and the fourth side of the first support member are positioned correspondingly. The third connecting assembly has the same structure as the first connecting assembly, and the fourth connecting assembly has the same structure as the second connecting assembly. This design allows the first support member to be subjected to more balanced forces, ensuring greater stability when the first support member moves relative to the second support member. At the same time, it can achieve more effective positioning of the first support member, ensuring that the first support member can accurately move in a set direction relative to the second support member.

[0017] Preferably, the second support member is a frame-like structure, with the first and second sides of the first support member both located at the outer edge of the first support member; the first side of the first support member is movably connected to the first inner side of the second support member via a first connecting assembly, and the second side of the first support member is movably connected to the second inner side of the second support member via a second connecting assembly. This design can further simplify the overall structure of the support member and reduce the overall weight of the support member.

[0018] Preferably, the first support member can be suspended in a first position and a second position relative to the second support member, respectively, and the first position and the second position are spaced apart along the direction of movement of the first support member relative to the second support member. In this way, in the initial state, the first support member is suspended in the first position; during the process of pressing the first support member, the first support member moves relative to the second support member. When the first support member moves to the second position and the pressure on the first support member stops, the first support member will be suspended in the second position. At this time, the first support member is suspended in the second position, preventing the first support member from moving freely relative to the second support member in the absence of external force.

[0019] In a second aspect, the present invention provides a medical device, comprising a needle device having a needle, and further comprising a movable assembly of the medical device, wherein the needle device is mounted on a first support member.

[0020] The beneficial effects of the medical device of the present invention are as follows: based on the design of the active components of the medical device, the overall thickness of the medical device can be made thinner and the overall weight is also lighter, which avoids easy scratching with the worn clothes during use, reduces the user's foreign body sensation, and improves the user experience. At the same time, the overall structure of this medical device is simpler and the cost is lower.

[0021] Preferably, the needle is a detection needle or an injection needle.

[0022] Preferably, the needle device is detachably connected to the first support member. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0039] Example 1

[0040] As shown in Figure 2, this embodiment provides a medical device movable component, including a support body 1, the support body 1 includes a first support member 11, a second support member 12, a first connecting component 13 and a second connecting component 14, the first side of the first support member 11 is movably connected to the second support member 12 through the first connecting component 13, and the second side of the first support member 11 is movably connected to the second support member 12 through the second connecting component 14, the first connecting component 13 can guide the first support member 11 to move relative to the second support member 12 along the first plane, and the second connecting component 14 can guide the first support member 11 to move relative to the second support member 12 along the second plane, the first plane intersects with the second plane and forms an intersection line, which is perpendicular to the installation surface, that is, the surface where the first and second support members are located, and under the action of force, can only move along the direction of the intersection line.

[0041] As shown in Figures 2 and 4, the movable assembly of the medical device is based on the first side of the first support member 11 being movably connected to the second support member 12 through the first connecting assembly 13, and the second side of the first support member 11 being movably connected to the second support member 12 through the second connecting assembly 14. The first connecting assembly 13 can guide the first support member 11 to move relative to the second support member 12 along the first plane, and the second connecting assembly 14 can guide the first support member 11 to move relative to the second support member 12 along the second plane, and the first plane intersects with the second plane and forms an intersection line, which is perpendicular to the mounting surface, so that the first support member 11 can only move relative to the second support member 12 along a straight line perpendicular to the mounting surface; in this way, the needle device 2 and the like can be installed on the first support member 11, and when in use, the second support member 12 is fixed to the human body. On the human skin, the surface of the human skin is the installation surface. Pressing any point on the first support member 11 will cause the first support member 11 to move toward the human skin together with the needle device 2, and the first support member 11 and the needle device 2 can only move in a direction perpendicular to the skin surface, thereby ensuring that the needle 21 of the needle device 2 can be vertically inserted into the skin to complete corresponding testing or injection needs; and this structural design does not require the first support member 11 and the second support member 12 to have a sliding contact part in a direction perpendicular to the skin, so that the overall thickness of the medical device movable component and the device with the medical device movable component can be thinner and lighter, avoiding easy scratches with worn clothes during use, reducing the user's foreign body sensation, and improving user experience. At the same time, this structural design is simpler and less costly.

[0042] Meanwhile, as shown in Figures 4 and 7, this embodiment provides a medical device comprising a needle device 2 and a movable assembly of the medical device, wherein the needle device 2 is mounted on a first support member 11. Based on the design of the movable assembly of the medical device, the overall thickness of the medical device can be made thinner and the overall weight is also lighter, thereby preventing easy scratching with clothing during use, reducing the user's foreign body sensation, and improving the user experience. At the same time, the overall structure of the medical device is simpler and the cost is lower.

[0043] Specifically, in this embodiment, the first plane and the second plane may intersect perpendicularly; or they may not intersect perpendicularly, as long as the intersection line is perpendicular to the installation surface.

[0044] Specifically, as shown in Figures 4 and 5, the first connecting assembly 13 in this embodiment includes a first connecting plate 131 and a second connecting plate 132. One end of the first connecting plate 131 is connected to the side of the first support member 11, the other end of the first connecting plate 131 is connected to one end of the second connecting plate 132, and the other end of the second connecting plate 132 is connected to the second support member 12. The angle A between the first connecting plate 131 and the second connecting plate 132 is variable, the angle B between the first connecting plate 131 and the first support member 11 is variable, and the angle C between the second connecting plate 132 and the second support member 12 is variable. This connection structure, based on the above-mentioned feature of variable angles, ensures that the first support member 11 can move smoothly in a set direction relative to the second support member 12 while achieving the corresponding position limiting function of the first support member 11. More specifically, in this embodiment, the first connecting component 13 also includes a first connecting portion 133, a middle connecting portion 134, and a second connecting portion 135. The lower end of the first connecting plate 131 is connected to the lower end of the first support member 11 through the first connecting portion 133, the upper end of the first connecting plate 131 is connected to the upper end of the second connecting plate 132 through the middle connecting portion 134, and the lower end of the second connecting plate 132 is connected to the second support member 12 through the second connecting portion 135. The first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 can all produce bending deformation. In this way, because the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 can all bend and deform, the angle A between the first connecting plate 131 and the second connecting plate 132 can be changed, the angle B between the first connecting plate 131 and the first support member 11 can be changed, and the angle C between the second connecting plate 132 and the second support member 12 can be changed, while also meeting the requirement for limiting the first support member 11. In other embodiments, the first connecting assembly 13 may further include a third connecting plate and a fourth connecting plate, that is, the first connecting assembly 13 may further include more than two connecting plates.

[0045] In this embodiment, the first connecting plate 131, the first support member 11, the second connecting plate 132, the second support member 12, the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 are made of plastic. The thicknesses of the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 are smaller than the thicknesses of the first connecting plate 131, the first support member 11, the second connecting plate 132, and the second support member 12. That is, the thicknesses of the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 are all smaller than the thickness of the first connecting plate 131, smaller than the thickness of the first support member 11, smaller than the thickness of the second connecting plate 132, and smaller than the thickness of the second support member 12. This material design allows the first connecting plate 131, the second connecting plate 132, the first support member 11, and the second support member 12 to maintain a predetermined shape, while also enabling the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 to have the desired bending deformation capability. In other embodiments, the first connecting plate 131, the first support member 11, the second connecting plate 132, the second support member 12, the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 are made of paper, rubber, metal, or a composite material. The composite material can be a combination of two or more of plastic, paper, rubber, and metal. In another embodiment, the strength of the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135 is less than the strength of the first connecting plate 131, the first support member 11, the second connecting plate 132, and the second support member 12. In another embodiment, the strength of the first connection portion 133, the middle connection portion 134 and the second connection portion 135 is less than the strength of the first connection plate 131, the first support member 11, the second connection plate 132 and the second support member 12, and the thickness of the first connection portion 133, the middle connection portion 134 and the second connection portion 135 is less than the thickness of the first connection plate 131, the first support member 11, the second connection plate 132 and the second support member 12.

[0046] The structure of the second connecting assembly 14 in this embodiment is identical to that of the first connecting assembly 13. Furthermore, the support body 1 in this embodiment is obtained through an integrated injection molding process. Thus, the obtained support body 1 is an integrated structure, i.e., the first support member 11, the second support member 12, the first connecting assembly 13, and the second connecting assembly 14 in this embodiment are an integrated structure. This reduces the number of parts, and thus allows the support body 1 to be quickly manufactured without the need for an assembly process. This not only saves assembly steps and reduces costs, but most importantly, it avoids assembly errors caused by the assembly process, improves the overall machining accuracy of the active component of the medical device, and thereby improves the monitoring accuracy of the monitoring system including the active component of the medical device. In other embodiments, the support body 1 can also be obtained by combining a hard material with a soft material. For example, a hard plate-like material can be made into the first connecting plate 131, the first support member 11, the second connecting plate 132, and the second support member 12, and a soft material (such as a film) can be pressed, glued, or riveted to the first connecting plate 131, the first support member 11, the second connecting plate 132, and the second support member 12 to form the support body 1. In this case, the soft material constitutes the first connecting portion 133, the middle connecting portion 134, and the second connecting portion 135. In this way, the support body 1 is subjected to very little frictional resistance during use, making operation more convenient.

[0047] In this embodiment, the first connection portion 133 can be a solid line structure, a dotted line structure, or a dotted structure; the middle connection portion 134 can be a solid line structure, a dotted line structure, or a dotted structure; and the second connection portion 135 can be a solid line structure, a dotted line structure, or a dotted structure. This design, while ensuring that the three connection portions have the required connection capacity, can effectively reduce the resistance that needs to be overcome when the three connection portions bend, thereby improving the flexibility of the first support member 11 relative to the second support member 12. The first connection portion 133, the second connection portion 135, or the middle connection portion 134 can be a single-point structure or a multi-point structure. The dotted line structure or the dotted connection can serve as a bridge, facilitating removal after installation and reducing the volume and weight after installation. In some embodiments, the first connection portion 133, the second connection portion 135, and the middle connection portion 134 are two-point structures, with the two connection points distributed at both ends of the straight line segment.

[0048] As shown in Figure 2, in this embodiment, the third side of the first support member 11 is movably connected to the second support member 12 via the third connecting assembly 15, and the fourth side of the first support member 11 is movably connected to the second support member 12 via the fourth connecting assembly 16. The first side and the second side of the first support member 11 are adjacent to each other; the first side and the third side of the first support member 11 are in corresponding positions, and the second side and the fourth side of the first support member 11 are in corresponding positions. The third connecting assembly 15 has the same structure as the first connecting assembly 13, and the fourth connecting assembly 16 has the same structure as the second connecting assembly 14. This design makes the force on the first support member 11 more balanced, ensuring that the first support member 11 is more stable when moving relative to the second support member 12. At the same time, it can achieve more effective positioning of the first support member 11, ensuring that the first support member 11 can accurately move in the set direction relative to the second support member 12.

[0049] More specifically, as shown in Figures 2 and 3, in this embodiment, the second support member 12 has a rectangular frame structure. The first side of the first support member 11 is movably connected to the first inner side of the second support member 12 via a first connecting assembly 13. The second side of the first support member 11 is movably connected to the second inner side of the second support member 12 via a second connecting assembly 14. The third side of the first support member 11 is movably connected to the third inner side of the second support member 12 via a third connecting assembly 15. The fourth side of the first support member 11 is movably connected to the fourth inner side of the second support member 12 via a fourth connecting assembly 16. The first, second, third, and fourth sides of the first support member 11 are all located at the outer edge of the first support member 11. This design can further simplify the overall structure of the support member and reduce the overall weight of the support member. In this embodiment, the first support member 11 is located in the hollow space of the frame of the second support member 12. The first support member 11 can reciprocate in the Z direction relative to the second support member 12. Double-sided tape is provided on the bottom surface of the second support member 12, and during use, the second support member 12 is fixed to the skin with the double-sided tape. In other embodiments, the second support member 12 has an arc-shaped structure. This embodiment is illustratively described using a rectangular structure. In other embodiments, the first support member 11 and the second support member 12 can also have a pentagonal, hexagonal, or multi-sided shape.

[0050] The movable component of the medical device in this embodiment can be a consumable. The movable component of the medical device in this embodiment has a simple structure and is relatively thin after the needle device 2 is installed, with a thickness of 3mm-6mm, which not only reduces the weight of the device but also reduces the cost of the device. At the same time, the thin thickness after installation is not easy to scratch clothing, thereby making the monitoring results more accurate. Compared with the piston-sleeve structure, the movable component of the medical device in this embodiment has almost no friction resistance during use and will not get stuck. In addition, the movable component of the medical device in this embodiment is manufactured in an integrated manner, which can not only improve the manufacturing effect, but also, the integrated structure does not require assembly, which can save assembly steps and avoid errors in the assembly process.

[0051] In this embodiment, the movable component of the medical device can serve as a probe component bracket or a bottom support bracket. When in use, the second support member 12 can be fixed to the skin around the target position of the human body by double-sided tape. The movable component of the medical device can be understood as a part of the overall medical device. The movable component of the medical device can be detachably connected to the needle device 2, or non-detachably connected, that is, the first support member 11 is detachably connected to the needle device 2, or non-detachably connected; when the movable component of the medical device is detachably connected to the needle device 2, after the needle device 2 is installed on the human skin using the movable component of the medical device and the needle 21 of the needle device 2 is vertically inserted into the skin, the movable component of the medical device can be removed, and only the needle device 2 remains on the skin. At this time, the movable component of the medical device is equivalent to an auxiliary device. When the medical device in this embodiment is in use, its second support member 12 can be fixed to the skin by double-sided tape. Pressing the first support member 11 will drive the needle device 2 to move perpendicular to the skin, and the needle 21 will vertically penetrate the skin to achieve the corresponding function. In this embodiment, the needle 21 may be a detection needle. Thus, when the needle 21 penetrates the skin, it can perform a corresponding detection function. In this case, the medical device is a monitoring device. In other embodiments, the needle 21 may be an injection needle. Thus, when the needle 21 penetrates the skin, it can inject a corresponding drug into the human body.

[0052] In this embodiment, the first connecting component 13 and the second connecting component 14 can be understood as a biaxial hinge. In this embodiment, the "hinge" structure can be realized by a single piece, such as by utilizing the flexibility and toughness of polymer materials. Specifically, in this embodiment, the first connecting component 13, the second connecting component 14 and the entire support body 1 can be made of polypropylene, polyethylene, polytetrafluoroethylene, or other plastic rubber materials. Due to the limitation of the first connecting component 13 and the second connecting component 14, the first support member 11 can only move up and down in the Z direction, and the first support member 11 will not move in the horizontal direction, that is, after the second support member 12 is fixed to the skin, the first support member 11 can only move vertically up and down relative to the skin. The movable component of the medical device set in this embodiment has a simple structure and a thin thickness, which not only reduces the weight of the device, but also reduces the cost of the device. At the same time, the thin thickness can reduce the brittleness of the device, making the device less susceptible to impact and vibration, thereby making the monitoring results more accurate.

[0053] Specifically, as shown in Figure 8, in this embodiment, the first connecting component 13 can be understood as a first hinge comprising line segments A1B1C1, A2B2C2, and A3B3C3; the second connecting component 14 can be understood as a second hinge comprising line segments D1E1F1, D2E2F2, and D3E3F3. The first hinge can guide the first support member 11 to move relative to the second support member 12 along a vertical plane S1, while the second hinge can guide the first support member 11 to move relative to the second support member 12 along a vertical plane S2. The vertical planes S1 and S2 intersect at line IJ. Vertical plane S1 is the first plane, vertical plane S2 is the second plane, and line IJ is the intersection line. Line IJ is perpendicular to the mounting surface. A perpendicular plane A1C1H is made through line segment A1C1 to intersect line IJ, and a perpendicular plane D1F1G is made through line segment D1F1 to intersect line IJ. In this embodiment, perpendicular plane A1C1H is parallel to or coincides with perpendicular plane D1F1G, and perpendicular plane S1 is not coincident with perpendicular plane S2.

[0054] As shown in Figures 4 and 7, in this embodiment, the first support member 11 is provided with a plurality of mounting slots 111. The bottom wall of the first support member 11 is provided with mounting holes. The electronic assembly 3 of the needle device 2 can be mounted in the mounting slots 111 of the first support member 11, and the needle 21 of the needle device 2 is inserted into the mounting holes. The electronic assembly 3 includes a battery 31, a battery cover 32, and a signal transmitter assembly 33. The battery 31 can be a standard part. The battery cover 32 can be manufactured by injection molding. The signal transmitter assembly 33 includes a housing and a PCB board. The housing is obtained by injection molding, and the housing and PCB board are then assembled to form the signal transmitter assembly 33. Furthermore, in this embodiment, the needle device 2 also includes a spring 22 electrically connected to the needle 21.

[0055] In this embodiment, the first support member 11 can hover at a first position and a second position relative to the second support member 12, respectively. The first position and the second position are spaced apart along the direction of movement of the first support member 11 relative to the second support member 12. In this way, in the initial state, in the absence of external force, the first support member 11 hovers at the first position, at which point the first support member 11 is located above the second support member 12. During the process of pressing the first support member 11 downward, the first support member 11 moves downward relative to the second support member 12. When the first support member 11 moves to the set position and the pressing of the first support member 11 stops, the first support member 11 will hover at the second position. At this point, the first support member 11 hovers at the current position, preventing the first support member 11 from moving freely relative to the second support member 12 in the absence of external force. In this embodiment, the first position and the second position are spaced apart along a straight line perpendicular to the plane where the first straight line and the second straight line are located. Specifically, the first position and the second position are spaced apart along the vertical direction.

[0056] In this embodiment, the structural design of the first connecting component 13 is reasonable, and it can lock the position of the first support member 11. Specifically, the first connecting component 13 can make the first support member 11 hover in the first position and the second position, and the first position and the second position are distributed along the upper and lower intervals, the first position is located above the skin, and the second position is close to the skin or in conflict with the skin; because the device can control the first support member 11 to hover in the first position and the second position, the device can be controlled more conveniently. In one embodiment, the method of achieving the first support member 11 hovering in the first position and the second position includes: setting the straight line segment of the connection part originally connected between the first support member 11 and the second support member 12 to a structure including a curved line segment and a broken line segment.

[0057] In this embodiment, the angle A between the first connecting plate 131 and the second connecting plate 132 is between 0 degrees and 180 degrees. This configuration allows the first connecting plate 131 and the second connecting plate 132 to deflect relative to each other. The angle B between the first connecting plate 131 and the first support member 11 is an obtuse angle, and the angle C between the second connecting plate 132 and the second support member 12 is an obtuse angle. The setting of the obtuse angle ensures that the first support member 11 can move up and down relative to the second support member 12 without being stuck, and at the same time, the first support member 11 can hover at the first support member 12 in the initial state. Position, the first position is located on the upper side of the second support member 12. During the process of pressing the first support member 11 to move downward relative to the second support member 12, when the first support member 11 moves to the set position, the pressing stops and the first support member 11 will hover at the second position. In addition, when the first support member 11 hovers at the first position or the second position, based on the setting of the obtuse angle, the first connecting plate 131 can support the first support member 11 when it is deflected to the maximum angle, that is, it can enable the first support member 11 to hover at the first position or the second position. In this embodiment, the first position and the second position are equivalent to two steady-state points. In other embodiments, the above-mentioned angles A, B, and C are between -180 degrees and +180 degrees.

[0058] In this embodiment, adjacent first and second connecting assemblies 13, 14 form an angle a, with the angle a ranging from 0 to 180°. In actual use, waterproofing is a consideration. To this end, as shown in Figures 2 and 6, a transition piece 4 is provided between adjacent first and second connecting assemblies 13, 14, or between two adjacent first connecting assemblies 13, or between two adjacent second connecting assemblies 14. The transition piece 4 is used to block the gap between adjacent first and second connecting assemblies 13, 14, or between two adjacent first connecting assemblies 13, or between two adjacent second connecting assemblies 14, thereby providing waterproofing and dustproofing. In other embodiments, the transition piece 4 may not be provided.

[0059] In another embodiment, the transition piece 4 has the same structure as the first connecting component 13 and the second connecting component 14. In this embodiment, the structure of the transition piece 4 can not only play a role in waterproofing and dustproofing, but also provide a reset force for the reset process, so that the first support member 11 is always between the first position and the second position. Specifically, in the middle of the first position and the second position, the first support member 11 is deformed by force when moving to the first position or the second position. Therefore, after losing the pressing force or the pulling force, the transition piece 4 will be reset to its original position, so that the first support member 11 is always in the middle of the first position or the second position. This can avoid the increase in the gap between the adjacent first connecting components 13 and the second connecting components 14, or the two adjacent first connecting components 13, or the two adjacent second connecting components 14 due to deformation, thereby achieving a better waterproof effect. In other embodiments, the transition piece 4 is a waterproof cloth.

[0060] Example 2

[0061] As shown in Figures 9 to 15, this embodiment provides a medical device, comprising a needle device 2 and a medical device movable assembly, wherein the needle device 2 is mounted on a first support member 11. The main difference between the medical device movable assembly in this embodiment and that in the first embodiment is that the opening of the mounting slot 111 provided on the first support member 11 in this embodiment is aligned with the direction in which the needle 21 of the needle device 2 extends. Specifically, the opening of the mounting slot 111 and the direction in which the needle 21 extends are both downwardly facing. The needle device 2 is mounted in the mounting slot 111 with the opening facing downwardly, and the needle device 2 is detachably connected to the mounting slot 111. During use, similarly, the second support member 12 can be placed against the skin, and pressing any point on the first support member 11 will drive the needle device 2 to move in a direction perpendicular to the skin, causing the needle 21 to vertically penetrate the skin. This facilitates the upward removal of the medical device movable assembly from the needle device 2, leaving the needle device 2 on the skin. This medical device, based on the design of the medical device movable component, not only enables the needle 21 of the needle device 2 to move in a direction perpendicular to the skin, but also has a thinner overall thickness, lighter weight, and is more convenient to use.

[0062] In other embodiments, the movable component of the medical device can also be assembled with other components to form a corresponding medical device to meet corresponding usage requirements.

That is, this embodiment adopts a hinged structure to replace the design of the connecting portion of embodiment 1. This design in this embodiment also realizes the function of changing the angle A between the first connecting plate 131 and the second connecting plate 132, changing the angle B between the first connecting plate 131 and the first support member 11, and changing the angle C between the second connecting plate 132 and the second support member 12; it enables the first support member 11 to move relative to the second support member 12, and at the same time, it can guide the first support member 11 to move relative to the second support member 12 along a set direction.
