Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a transmitter module, a human body index monitoring device and a use method thereof. Background Art

[0002] For diseases that require long-term monitoring of specific body indicators, such as diabetes, a device that can continuously monitor human body indicators is needed to help patients complete data collection and analysis in real time. Currently, this type of device has a complex structure and is not easy to use. Summary of the invention

[0003] Human index detection equipment generally consists of four parts: sensor: used to be implanted in the human body, by converting chemical reactions into electrical signals; signal transmitter: used to transmit the electronic signals collected by the sensor to the device (such as a mobile phone) through radio signals; sensor guide needle: the sensor (which may be soft) is placed in the needle (such as a hard metal needle), the needle and the sensor are inserted into the human body, and then the needle is pulled out (needle return), and the sensor will remain in the human body; sealing component: because the sensor and needle need to be inserted into the human body, it is necessary to ensure that these two components are kept sterilized before insertion to avoid infection, and the plastic needle handle of the needle is passed through the hole in the middle of the transmitter, and then screwed together with the sealing sleeve on the other side.

[0004] In some cases, the sealing structure of the sensor and the needle requires the plastic handle of the needle to pass through the lower cover of the transmitter and expose enough length for the sleeve to engage. Therefore, when the user uses it, after removing the sleeve and before injecting the needle into the human body, it is necessary to step back once to retract the plastic handle exposed from the bottom cover of the transmitter to avoid hitting the human body and hindering the transmitter from sticking to the human body surface. Therefore, the movement of the needle-assisting module is complicated. Among them, the needle-assisting module refers to a component used to inject the needle and sensor of the transmitter module along the injection direction, so that the needle carrying the sensor is injected into the human body, and the needle can be retracted to pull the needle out of the human body.

DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 creative work are within the scope of protection of the present invention.

[0057] The human index monitoring device provided in the embodiment of the present application may specifically be a blood glucose meter, which is used to help diabetic patients monitor changes in blood glucose levels over a long period of time. However, it is not limited to a blood glucose meter, and may also be a device for collecting and analyzing other specific body indicators.

[0058] In order to have an overall understanding of the human body index monitoring, the human body index monitoring device provided in the embodiment of the present application is briefly introduced below.

[0059] Figure 1 The overall structure diagram of the human body index monitoring device provided in the embodiment of the present application is shown in FIG. Figure 1 The human index monitoring device provided in the embodiment of the present application includes a transmitter module 100 and a needle assisting device module 200, wherein the needle assisting device module 200 may include a main body a and a bottom shell b, the transmitter module 100 may be installed inside the bottom side of the main body a, and the bottom shell b may be fixed to the bottom side of the main body a to physically protect the transmitter module 100. The main body a of the needle assisting device module 200 is mainly used to inject the needle 150 (for example, a hard metal needle) and the sensor 130 of the transmitter module 100 along the injection direction P1, inject the needle 150 carrying the sensor 130 into the human body M1, and perform a needle return operation on the needle 150 along the needle return direction P2, pull the needle out of the human body M1, and leave the sensor in the human body M1. Afterwards, the transmitter may be connected to the sensor signal, and the signal collected by the sensor may be transmitted to an additional device such as a mobile phone through the transmitter in a wireless communication manner, wherein the needle return direction P2 is opposite to the injection direction P1. After the sensor is left in the human body M1, it may be connected to the transmitter by signal, but it may also be directly connected to an additional device such as a mobile phone. This optional feature can be applied to the embodiments of the entire invention and specification.

[0060] The structure of the main body a is described below using its assembly process:

[0061] Figure 2 express Figure 1 The exploded view of subject a in the figure. Figure 3a express Figure 2 A schematic diagram of the structure of the middle main support 205, the first elastic reset member 206 and the basic support member 207 after assembly, Figure 3b express Figure 3a A schematic diagram of the structure of the middle main support 205; Figure 2 , Figure 3a and Figure 3b The base support member 207 may include a main sleeve with an opening facing the injection needle direction P1, and the main sleeve may include a coaxial inner cylinder 2071 and an outer cylinder 2072, and the bottom of the inner cylinder 2071 may have a certain depression relative to the bottom of the outer cylinder 2072 along the injection needle direction P1.

[0062] The main bracket 205 may include a base 2051 and a first locking member 2055 and a second locking member 2052 connected to the base 2051, wherein the first locking member 2055 and the second locking member 2052 may have various forms, for example, the first locking member 2055 may be a first buckle (the figure mark also uses 2055), and the second locking member 2052 may be a second buckle (the figure mark also uses 2052).

[0063] The first elastic return member 206 can specifically be a coil spring and may be sleeved between the inner cylinder 2071 and the outer cylinder 2072. The recessed portion of the bottom of the inner cylinder 2071 and the cylinder wall of the outer cylinder 2072 may form a limit for the corresponding end of the first elastic return member 206, and the other end of the first elastic return member 206 may abut against the base 2051.

[0064] Along the injection direction P1, the main support 205 may have an initial position, an unlocking position and an injection position. The bottom of the main sleeve (specifically, the bottom of the inner sleeve 2071) may be provided with a clamping hole K corresponding to the second clamping buckle 2052, and the second clamping buckle 2052 may be clamped in the above-mentioned clamping hole K to compress the first elastic reset member 206. At this time, the first elastic reset member 206 may store elastic potential energy, and the main support 205 is in the initial position. The first elastic reset member 206 may be used to provide the above-mentioned main support 205 with a first elastic reset force to return from the initial position to the injection position along the injection direction P1. The first elastic reset force keeps the main support 205 from the initial position to the injection position. In addition, the first elastic reset member 206 uses a spiral spring to provide uniform elastic support for the main support 205 and the main sleeve at various positions in the circumferential direction. However, it should be understood that the first elastic reset member 206 is not limited to the coil spring, as long as it can provide the first elastic reset force for the main support 205 to return from the initial position to the injection position.

[0065] Specifically, the second buckle 2052 has an inclined guide surface S2 and a horizontal clamping surface S1 which are relatively arranged along the needle injection direction P1, and the horizontal clamping surface S1 may be clamped to the bottom of the inner cylinder 2071. However, the second locking member 2052 is not limited to the form of the second buckle 2052, as long as the second locking member 2052 is locked with the basic support member 207 when the main bracket 205 is located at the initial position, and the locking form can be other various forms.

[0066] The base 2051 may have a needle handle through hole T1 (refer to Figure 3b ), the needle handle through hole T1 is for the needle handle 151 of the needle 150 to pass through. Specifically, the base 2051 can be in a circular ring, a triangle or other shapes, and the middle hole serves as the needle handle through hole T1.

[0067] There can be multiple second buckles 2052, and multiple second buckles 2052 are arranged around the needle handle through hole T1, so that multiple second buckles 2052 can be used to more stably lock the main bracket 205 and the basic support member 207 in the circumferential direction. There can also be multiple clamping holes K, which are arranged in a one-to-one correspondence with the multiple second buckles 2052 in position, and each second buckle 2052 is clamped in a corresponding clamping hole K.

[0068] Figure 4 Indicated in Figure 3a The schematic diagram of the structure after the needle support 204 and the second elastic reset member 203 are installed in the structure shown in FIG. Figure 4 The needle holder 204 may include an inner tube wall 2041 and an outer tube wall 2042. The top of the inner tube wall 2041 and the top of the outer tube wall 2042 may be connected together, the bottom of the inner tube wall 2041 and the bottom of the outer tube wall 2042 may form an opening, and the bottom of the inner tube wall 2041 may form a hook 2043 for clamping the needle handle 151 of the needle 150.

[0069] exist Figure 4 In the embodiment, the needle support 204 is located in the needle handle through hole T1, the main support 205 may be located in the initial position, the first buckle 2055 may be located in the main sleeve, specifically, in the inner cylinder 2071 of the main sleeve, the first buckle 2055 is engaged with the needle support 204, and the needle support 204 is limited in the needle return direction P2 to prevent the needle support 204 from moving along the needle return direction P2, thereby achieving the locking of the first buckle 2055 and the needle support 204. In addition, the first buckle 2055 may be sandwiched between the needle support 204 and the basic support member 207, and the first buckle 2055 is limited by the basic support member 207 and the needle support 204 to prevent it from being separated from the needle support 204, thereby unlocking the needle support 204. The first locking member 2055 is not limited to the form of the first buckle 2055 , as long as when the main support 205 is located at the initial position, the first locking member clip 2055 is disposed between the needle support 204 and the base support 207 , and is locked with the needle support 204 .

[0070] Specifically, continue to refer to Figure 4 The first buckle 2055 may have an inclined blocking surface S4, and the edge of one end of the needle support 204 in the needle return direction P2 may be formed with an inclined chamfered surface S5. When the main support 205 is located at the initial position, the inclined blocking surface S4 of the first buckle 2055 abuts against the inclined chamfered surface S5.

[0071] Once the first buckle 2055 is unlocked, the needle holder 204 may move toward the needle return station under the action of the second elastic reset member 203, and use the inclined chamfered surface S5 to push the inclined blocking surface S4 along the needle return direction P2. Due to the guiding effect of the inclined blocking surface S4 and the inclined chamfered surface S5, the needle holder 204 may use the inclined chamfered surface S5 to push the first buckle 2055 laterally, thereby releasing the first buckle 2055 from limiting the needle holder 204 in the needle return direction P2.

[0072] When the base 2051 has the needle handle through hole T1, the number of the first buckles 2055 may be multiple, and the multiple first buckles 2055 may be evenly spaced and distributed around the needle handle through hole T1 to achieve uniform and stable limiting of the needle support 204 in the circumferential direction.

[0073] When there are multiple first buckles 2055 and multiple second buckles 2052, the numbers of the two can be the same, for example, 3. Multiple first buckles 2055 and multiple second buckles 2052 may be arranged alternately in sequence so that the first buckles 2055 and the second buckles 2052 can be distributed more evenly.

[0074] Along the needle return direction P2, the needle support 204 may have an original position and a needle return position relative to the main support 205. The base 2051 may be provided with a transmitter support 202 in the needle injection direction P1, and the transmitter support 202 and the base 2051 may be connected (such as by a buckle). The second elastic reset member 203 may be a coil spring, one end of which may abut against the angle formed by the top of the inner tube wall 2041 and the top of the outer tube wall 2042, and the other end of which may abut against the transmitter bracket 202. The transmitter bracket 202 is used to compress the second elastic reset member 203. At this time, the needle bracket 204 may be in the original position relative to the main bracket 205. The second elastic reset member 203 may store elastic potential energy, providing the needle bracket 204 with a second elastic reset force to return from the original position to the needle return position along the needle injection direction P1. The second elastic reset force keeps the needle bracket 204 from returning to the needle return position from the original position. In addition, the second elastic reset member 203 adopts a coil spring to provide uniform elastic support for the needle bracket 204 and the transmitter bracket 202 at various positions in the circumferential direction. However, it should be understood that the second elastic reset member 203 is not limited to a coil spring, as long as it can provide the needle bracket 204 with a second elastic reset force to return from the original position to the needle return position.

[0075] The basic support member 207 may have an escape groove U, which may be formed on the inner wall of the main sleeve, specifically, the inner wall of the inner cylinder 2071. However, depending on the form of the basic support member 207, the escape groove U may also be located at other positions of the basic support member 207. When the main support 205 is located at the unlocking position, at least a portion of the first locking member 2055 may be located in the escape groove U, and at this time, the first locking member 2055 releases the lock on the needle support 204.

[0076] Figure 5 Indicated in Figure 4 The schematic diagram of the structure after the first sub-housing 2081, the second sub-housing 2082 and the decorative ring 201 are added to the structure shown in FIG. Figure 5 The first sub-housing 2081 and the second sub-housing 2082 may be assembled on both sides of the base support 207 in a snap-fitting manner and may be fixed to the base support 207. The decorative ring 201 may be snap-fitted to the bottom sides of the first sub-housing 2081 and the second sub-housing 2082. The first sub-housing 2081, the second sub-housing 2082 and the decorative ring 201 serve as an appearance decoration.

[0077] Figure 6 Indicated in Figure 5 The schematic diagram of the structure after adding the injection needle switch 210 and the third elastic reset member 209 to the structure shown in the figure, the needle assisting device module can also include the injection needle switch 210, and the injection needle switch 210 can specifically include a button slidably connected to the basic support member 207 along the injection needle direction P1, and the button may be located in the needle return direction P2 of the basic support member 207, and specifically can be installed in the slide groove formed by the inner cylinder 2071 of the basic support member 207 being recessed relative to the outer cylinder 2072 along the injection needle direction P1, and a third elastic reset member 209 may be provided between the button and the bottom of the slide groove, and the third elastic reset member 209 may be a coil spring, and the button abuts against the inclined guide surface S2 (reference Figure 3a ), and when the button is pressed, the button may move along the injection needle direction P1, and the button applies a thrust to the inclined guide surface S2 along the injection needle direction P1, and while pushing the inclined guide surface S2 toward the injection needle direction P1, the second buckle 2052 may be moved in the horizontal direction, so that the second buckle 2052 is disengaged from the clamping hole K, and the second buckle 2052 is unlocked from the base support member 207. However, it should be understood that the injection needle switch 210 is not limited to the form of the above-mentioned button, and may also be in the form of a rotary knob, as long as the injection needle switch 210 can unlock the second locking member after the injection needle switch 210 is operated.

[0078] Figure 7 express Figure 6 Schematic diagram of the external structure of the structure shown. Figure 6 and Figure 7An anti-accidental-touch handle 2101 is fixedly connected to the injection needle switch 210, and the anti-accidental-touch handle 2101 can be broken off from the injection needle switch 210. Before the anti-accidental-touch handle 2101 is broken off, the anti-accidental-touch handle 2101 may be stuck on the first sub-shell 2081 and the second sub-shell 2082 along the injection needle direction P1 to prevent the button from being pressed due to accidental touch.

[0079] Back to Figure 4 The main bracket 205 may also include a third buckle 2053 connected to the base 2051. When the basic support member 207 may include a main sleeve with an opening facing the injection needle direction P1, the inner wall of the main sleeve may have a slot V, which may be specifically located in the side wall of the inner cylinder 2071. The slot V may be a groove or a through groove that passes through the side wall of the inner cylinder 2071. When the main bracket 205 is located at the injection needle station, the locking positioning surface S3 below the third buckle 2053 may be engaged with the slot V to prevent the main bracket 205 from continuing to slide along the injection needle direction P1 and detaching from the basic support member 207.

[0080] exist Figure 4 In the embodiment, each third buckle 2053 and a corresponding second buckle 2052 may be an integrated structure, and the two may face in opposite directions, thereby saving space on the base 2051. However, it should be understood that the third buckle 2053 and the second buckle 2052 may also be independent split structures, as long as they can respectively realize their respective functions.

[0081] The transmitter module 100 is introduced below with reference to the accompanying drawings.

[0082] Figure 8 express Figure 1 A schematic diagram of the structure of the transmitter bottom shell 121 and the sleeve 110 of the transmitter module 100 after assembly, Fig. 9 express Figure 8 The structure shown is a schematic diagram of the structure after the sensor 130, the sealing bracket 140 and the needle 150 are assembled. Fig.10a express Fig. 9 The corresponding assembly drawing, combined with Figure 8 , Fig. 9 and Fig.10aThe transmitter module 100 may include a transmitter bottom shell 121 and a sleeve 110. The transmitter bottom shell 121 may have an avoidance through hole W, and the sleeve 110 may be sealed and connected to the outer surface S6 of the transmitter bottom shell 121. The entire edge of one end of the sleeve 110 facing the outer surface S6 may have no gap with the outer surface S6, and the corresponding end of the sleeve 110 surrounds the avoidance through hole W. There are many ways to seal the outer surface S6 of the sleeve 110 and the transmitter bottom shell 121. For example, the end of the sleeve 110 facing the transmitter bottom shell 121 may have an annular connection portion 111 and an annular support table 113. The annular connection portion 111 and the transmitter bottom shell 121 may be fixedly connected. The annular connection portion 111 mainly plays a fixed connection role. When the needle 150 needs to be used for needle injection, it is only necessary to unscrew the sleeve 110. A first sealing rubber ring 112 may be provided between the annular support table 113 and the transmitter bottom shell 121. The first sealing rubber ring 112 may be squeezed by the annular support table 113 and the transmitter bottom shell 121 in the axial direction P of the sleeve 110, thereby achieving sealing between the annular support table 113 and the transmitter bottom shell 121. Among them, the annular support table 113 can be located at the periphery of the annular connection portion 111, and the first sealing rubber ring 112 is used to simultaneously protect the connection between the annular connection portion 111 and the transmitter bottom shell 121. There are many ways to fix the annular connection part 111 and the transmitter bottom shell 121. While ensuring the fixed connection, the firmness of the connection between the annular connection part 111 and the transmitter bottom shell 121 should not be too strong, so that the sleeve 110 can be manually unscrewed when the needle 150 is used for the injection operation. For example, the annular connection part 111 and the transmitter bottom shell 121 are fixed by ultrasonic welding or glue. The annular connection part 111 and the transmitter bottom shell 121 can both be made of plastic materials, such as PC (Polycarbonate) and ABS (Acrylonitrile Butadiene Styrene plastic). The two may be ultrasonically welded, and the welding quality is stable. Compared with the form of snap connection, there is no need for a complex snap-on structure between the sleeve and the bottom shell, and the space requirement is reduced. However, the method of fixing the annular connection part 111 and the transmitter bottom shell 121 does not exclude the form of snap connection.

[0083] The needle 150 may include a needle body 152 and a needle handle 151 connected to one end of the needle body 152. The needle handle 151 may also be made of plastic materials such as PC and ABS. The needle 150 passes through the avoidance through hole W, and the end away from the needle handle 151 is located in the sleeve 110. The sensor 130 may be inserted in the needle body 152. The needle body 152 may specifically be made of metal and have sufficient hardness. The corresponding end of the needle body 152 can be buried in the needle handle 151. The needle body 152 passes through the avoidance through hole W, and the end away from the needle handle 151 can be located in the sleeve 110. The sensor 130 may be inserted into the needle body 152. For example, the needle body 152 has a notch extending along its length, and a portion of the sensor 130 enters the needle body 152 through the notch. When the needle 150 is injected, the harder needle body 152 plays a guiding role, helping the softer sensor 130 to enter the human body M1. When the needle 150 is retracted, the needle body 152 is pulled out of the human body M1, and the sensor 130 slides out of the needle body 152 through the notch of the needle body 152 and remains in the human body M1.

[0084] Among them, the needle handle 151 may be located on the side of the transmitter bottom shell 121 away from the sleeve 110, and may be sealed and connected to the transmitter bottom shell 121 to block the above-mentioned avoidance hole W, and cooperate with the transmitter bottom shell 121 and the sleeve 110 to form an enclosed space to provide an enclosed sterile space for the needle body 152 and the sensor 130.

[0085] The needle body 152 can be released from the avoidance through hole W, so that the avoidance through hole W limits the needle body 152 throughout the injection and needle return process, especially when returning the needle, which can prevent the needle body 152 from shaking and deflecting and causing bleeding for the user.

[0086] There may be various forms of sealing connection between the needle handle 151 and the transmitter bottom shell 121, as long as the above-mentioned closed sterile space can be formed.

[0087] For example, the transmitter module 100 may also include a sealing bracket 140 located between the transmitter bottom shell 121 and the needle handle 151. The sealing bracket 140 may also be made of plastic materials such as PC and ABS. The sealing bracket 140 may include an annular support plate 142 and an annular protrusion 141 connected to the side surface of the annular support plate 142. The transmitter bottom shell 121 may have an annular groove F surrounding the avoidance through hole W. The annular protrusion 141 is located in the annular groove F, and the annular groove F may be filled with sealant 144. The sealant 144 can be first applied to the annular groove F, and then the annular protrusion 141 is placed in the annular groove F. The sealant 144 is filled between the bottom of the annular protrusion 141 and the bottom surface of the annular groove F, thereby forming a seal between the sealing bracket 140 and the transmitter bottom shell 121. The annular support plate 142 may overlap the transmitter bottom shell 121 to provide stable support for the sealing bracket 140. The sealing bracket 140 may further include an annular enclosure 143 coaxial with the annular protrusion 141 . The annular enclosure 143 is located on a side of the annular support plate 142 away from the annular protrusion 141 and is used to position the needle handle 151 .

[0088] Specifically, the transmitter bottom shell 121 may have an annular boss 1211 surrounding the avoidance through hole W, an annular groove F is provided on the annular boss 1211, and the annular support plate 142 may overlap the annular boss 1211. The sensor 130 may include a vertical portion 131 and a horizontal portion 132 connected to one end of the vertical portion 131, the vertical portion 131 is located in the needle body 152, and is used to collect corresponding indicators in the human body M1, and the horizontal portion 132 may be located on the side of the transmitter bottom shell 121 away from the outer surface S6, and may be fixed to the transmitter bottom shell 121, such as by snapping.

[0089] For example, the needle handle 151 has a step surface R, and a second sealing rubber ring 153 may be provided between the step surface R and the annular boss 1211. The second sealing rubber ring 153 is pressed onto the annular boss 1211 by the step surface R to achieve sealing between the needle handle 151 and the annular boss 1211. In addition, the step surface R and the second sealing rubber ring 153 may have two contact surfaces, which increases the contact area and improves the sealing effect.

[0090] refer to Fig.10b , Fig.10c and Fig.10d The annular boss 1211 may be provided with a first slit G1, and the annular protrusion 141 may be provided with a second slit G2 corresponding to the first slit G1. The horizontal portion 132 penetrates the first slit G1 and the second slit G2, so that the horizontal portion 132 can be used to lead out the signal collected by the vertical portion 131. The first slit G1 and the second slit G2 may also be filled with the above-mentioned sealant 144 to maintain the sealing of the above-mentioned enclosed space and provide good sterile conditions for the needle body 152 and the sensor 130.

[0091] Fig.11 Express Fig.10a Schematic diagram of the structure shown in Figure 1 for irradiation sterilization, see Fig.11 The transmitter bottom shell 121, the needle handle 151, the sealing bracket 140 and the sleeve 110 can all be made of transparent materials, such as transparent plastic, so as to facilitate irradiation sterilization, and sterilize the enclosed space where the needle body 152 and the sensor 130 are located to form a sterile environment.

[0092] As described above, since the needle handle 151 does not need to pass through the transmitter bottom shell 121 to connect with the sleeve 110 to form a seal, the extra redundant needle return action is avoided, and after the injection is completed, only one needle return is required.

[0093] Fig.12 Indicated in Fig.11 The exploded view of the structure shown in FIG. 1 after the transmitter top shell 122 and the circuit board 123 are added to the structure shown in FIG. Fig.13 express Fig.12 The exploded diagram of the assembly structure shown in the exploded diagram is combined with the exploded diagram of the assembly structure with the release paper and the adhesive. Fig.12 and Fig.13 , the transmitter top shell 122 may be located on the side of the transmitter bottom shell 121 away from the sleeve 110, and enclose a storage space with the transmitter bottom shell 121. The storage space may also be provided with a circuit board 123 and a connector 125. The sensor 130 may be connected to the circuit board 123 through the connector 125 to transmit the signal collected by the sensor 130 to the circuit board 123, and after being processed by the relevant components on the circuit board 123, it is sent to a visual device such as a mobile phone in a wireless form. The circuit board 123 is provided with a battery 124, and the battery 124 is used to power the sensor 130. In order to increase the usable area of ​​the circuit board 123, the circuit board 123 may include a first plate portion 1231 and a second plate portion 1232. One end of the first plate portion 1231 and one end of the second plate portion 1232 may be bent and connected through a connecting portion 1233. The flexible circuit board can be cut into the above shape, and the first plate portion 1231 and the second plate portion 1232 can be bent to be arranged relative to each other. The first plate portion 1231 and the second plate portion 1232 may both be provided with a hollow structure for the needle handle 151 to pass through.

[0094] The first plate portion 1231 may be located between the second plate portion 1232 and the transmitter top shell 122 to be arranged close to the transmitter top shell 122. One end of the first plate portion 1231 away from the connecting portion 1233 abuts against the surface of the annular support plate 142 facing the transmitter bottom shell 121, and the annular support plate 142 is used to limit the first plate portion 1231.

[0095] Fig.14 express Fig.13 For the corresponding assembly drawing, refer to Fig.13 and Fig.14 , the transmitter bottom shell 121, the transmitter top shell 122 and the part therebetween may form a transmitter N, the outer surface S6 of the transmitter bottom shell 121 may be provided with an adhesive 161, and the surface of the adhesive 161 may be provided with a release paper 162. When the needle body 152 of the needle 150 is injected into the human body M1, the transmitter bottom shell 121 may be attached to the skin surface of the human body M1 through the adhesive 161, and the transmitter bottom shell 121 may be attached to the skin surface through the adhesive 161 to send the signal collected by the sensor 130 in a wireless form.
