Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a radial artery puncture device. Background Technology

[0002] In clinical practice, radial artery puncture is a routine procedure used by healthcare professionals when arterial blood needs to be collected for blood gas analysis, certain interventional treatments, or continuous arterial blood pressure monitoring. When performing radial artery puncture, an assistant is needed to stabilize the patient's wrist, and the artery's location cannot be accurately pinpointed, especially in patients with thin or weak arteries, where control is often unstable, and the cannula frequently fails to penetrate the artery when the skin is punctured. Therefore, healthcare professionals often need to use a radial artery puncture guidance device in conjunction with a patient hand stabilization device to perform radial artery puncture.

[0003] However, in related technologies, the radial artery puncture guiding device and the patient's hand fixation device are usually two separate devices. Operating these two devices separately increases the steps and difficulty for medical staff, potentially delaying treatment in emergencies. Furthermore, the separate devices cannot provide sufficient stability when fixing the patient's hand and guiding the puncture. Especially for uncooperative patients or when the patient's limbs tremble due to pain during the puncture, the separate components cannot effectively restrict hand movement, leading to puncture failure or complications.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] like Figure 1 and Figure 5As shown, this application provides a radial artery puncture device, which includes: a fixation component 100 and a puncture guide component 200; the fixation component 100 is used to fix the patient's hand; the puncture guide component 200 includes: a first balloon 210 and a puncture guide mechanism 220; the first balloon 210 is used to fix the patient's hand in conjunction with the fixation component 100 after inflation; the puncture guide mechanism 220 includes: a fixation part 221, a rotating part 222 and a puncture part 223; the fixation part 221 is connected to the first balloon 210, the rotating part 222 is rotatably connected to the fixation part 221 along a first direction (X) away from the first balloon 210, and the puncture part 223 is slidably connected to the rotating part 222, and the puncture part 223 is used to place a puncture needle.

[0028] Specifically, the puncture guide component 200 is disposed on the side of the fixation component 100 along the first direction (X), so that the first airbag 210, after inflation, can cooperate with the fixation component 100 to fix the patient's hand. The puncture guide mechanism 220 includes a fixation component 221, a rotating component 222, and a puncture component 223. The fixation component 221 is connected to the first airbag 210. In some embodiments, the fixation component 221 and the first airbag 210 are fixedly bonded by an adhesive material. This application does not limit the fixation method.

[0029] A rotating component 222 is disposed on the side of the fixed component 221 away from the first airbag 210 in the first direction (X), and the rotating component 222 is rotatably connected to the fixed component 221. In some embodiments, the fixed component 221 includes two second support members 2212 respectively disposed on opposite sides of the fixed component 221 along a third direction (Z). The second support members 2212 extend along the first direction (X), and a rotating shaft extending along the third direction (Z) and rotatably connected to the two second support members 2212 is disposed between the two second support members 2212 disposed opposite to each other in the third direction (Z). The rotating shaft passes through the rotating component 222 and is fixedly connected to the rotating component 222, so that the rotating component 222 can rotate along the rotating shaft under the support of the two second support members 2212. In some other embodiments, the fixing member 221 includes two second support members 2212 respectively disposed on both sides of the fixing member 221 along a third direction (Z), the second support members 2212 extending along a first direction (X), and the two second support members 2212 respectively rotatably connected to the rotating part so that the rotating part can rotate along the two support members.

[0030] The puncture component 223 is used to place the puncture needle. The puncture component 223 is slidably connected to the rotating component 222 on the side away from the first airbag 210 along the first direction (X). The projection of the sliding direction of the puncture component 223 reciprocates along the second direction (Y). In some embodiments, the puncture component 223 is a cylinder. A slider is provided on the side of the cylinder near the rotating component 222 along the first direction (X). A slide rail that cooperates with the slider is provided on the side of the rotating component 222 near the cylinder along the first direction (X). The slide rail is provided along the second direction (Y), and the puncture component 223 can slide along the slide rail.

[0031] When using the radial artery puncture device, place the patient's hand appropriately between the first balloon 210 and the fixation component 100. Inflate the first balloon 210 to cooperate with the fixation component 100, achieving stable fixation of the patient's hand through synergy, thereby reducing hand movement during the puncture process. Since the puncture guide component 200 is fixedly connected to the first balloon 210, place the puncture needle in the puncture component 223. Rotate the rotating component 222 to adjust the puncture needle to the appropriate puncture angle according to the specific location and direction of the radial artery. Finally, slide the puncture component 223 to ensure a stable puncture process, thereby accurately completing the radial artery puncture operation.

[0032] Understandably, the radial artery puncture device includes a fixation component 100 and a puncture guiding component 200. The fixation component 100 is responsible for fixing the patient's hand, and the puncture guiding component 200 includes a first balloon 210 and a puncture guiding mechanism 220. After inflation, the first balloon 210 can cooperate with the fixation component 100 to fix the patient's hand. The puncture guiding mechanism 220 consists of a fixation part 221, a rotating part 222, and a puncture part 223. The fixation part 221 is connected to the first balloon 210, the rotating part 222 is rotatably connected to the fixation part 221 along a first direction (X) away from the first balloon 210, and the puncture part 223 is slidably connected to the rotating part 222 and is used to place the puncture needle. By integrating the puncture guide component 200 onto the fixation component 100, medical personnel can simultaneously use the fixation component 100 to immobilize the patient's hand and operate the puncture guide component 200 for puncture. This reduces the number of steps required by medical personnel, simplifies the procedure, saves time in emergencies, and facilitates rapid patient treatment. Simultaneously, the first airbag 210, after inflation, works in conjunction with the fixation component 100 to immobilize the patient's hand. Compared to using the fixation device alone, the synergistic effect of the two provides a stronger immobilization effect, significantly enhancing the stability of the patient's hand fixation, effectively restricting hand movement, thereby ensuring a smooth puncture, reducing the risk of puncture failure, and minimizing the occurrence of complications.

[0033] Optional, such as Figure 1 and Figure 4As shown, the first airbag 210 includes a support plate 211 and an airbag bag 212; the support plate 211 and the airbag bag 212 are connected along the first direction (X) to the side near the fixing member 221; the support plate 211 includes a first groove 2111; the fixing member 221 includes a protrusion 2211 that mates with the first groove 2111, and the protrusion 2211 is connected to the first groove 2111.

[0034] Specifically, the first airbag 210 includes a support plate 211 and an inflatable airbag bag 212. The support plate 211 is disposed on the side of the airbag bag 212 along the first direction (X) near the fixing member 221. The support plate 211 and the airbag bag 212 can be bonded and fixed with an adhesive substance; this application embodiment does not limit the specific connection method. The material of the support plate 211 can be rigid plastic or rigid metal; this application embodiment does not limit the specific material.

[0035] The support plate 211 is provided with a first groove 2111 on the side away from the airbag 212 along the first direction (X). The first groove 2111 can be provided along the second direction (Y) or the third direction (Z). This application embodiment does not limit it.

[0036] The fixing component 221 includes a protrusion 2211 that engages with the first groove 2111. The protrusion 2211 can be accommodated in the first groove 2111 and engage with the first groove 2111 so that the fixing component 221 can be securely fixed on the support plate 211.

[0037] Understandably, by connecting the support plate 211 and the airbag 212 in a specific direction, the support plate 211 can provide a rigid support base for the airbag 212, ensuring stable pressure on the patient's hand after inflation. At the same time, the groove of the support plate 211 and the protrusion 2211 of the fixing component 221 can be connected to achieve a stable assembly of the puncture component 223 and the first airbag 210. This not only ensures the positional accuracy of the puncture component 223 during the fixation process, but also facilitates disassembly and adjustment. The inflation force of the airbag 212 and the rigid support of the support plate 211 form a synergistic fixation effect, effectively improving the reliability of the patient's hand fixation and the stability of the puncture guidance. Especially when facing different hand shapes or needing to adjust the puncture angle, the structure can be flexibly positioned, reducing the operational difficulty for medical staff and improving puncture efficiency and accuracy.

[0038] Optional, such as Figure 4 As shown, the amount of expansion and contraction of the airbag 212 along the first direction (X) increases along the second direction (Y); the fixing component 100 is disposed on the side of the airbag 212 with a smaller amount of expansion and contraction along the second direction (Y).

[0039] Specifically, the balloon 212 extends along the second direction (Y) from the side closer to the fixation component 100 to the side farther from the fixation component 100, while its extension along the first direction (X) increases. During use, the balloon 212 is inflated, extending along the first direction (X). The patient's palm is inserted from the side of the balloon 212 with the smaller extension in the first direction (X) (closer to the wrist). After inflation, the pressure exerted by the balloon 212 on the side of the patient's palm closer to the fingertips (the end with the larger extension) is greater than the pressure exerted on the side closer to the wrist (the end with the smaller extension), causing the patient's wrist to naturally bulge along the first direction (X), forming a stable puncture support surface, facilitating precise positioning and puncture operation by medical personnel.

[0040] In some embodiments, the airbag 212 includes a miniature air pump, and the airbag 212 is provided with an inflation port connected to the miniature air pump for inflating the airbag 212. The miniature air pump can be a manually controlled inflation pump or an electrically controlled inflation pump; this embodiment does not limit its use. Medical personnel can control the degree of inflation of the airbag 212 by controlling the miniature air pump according to specific needs. It is understood that the airbag 212 exhibits a characteristic of gradually increasing expansion and contraction along the second direction (Y) and the fixing component 100 is located on the side with smaller expansion and contraction. This design allows the airbag 212 to provide differentiated support and fixation for the patient's hand after inflation. The area closer to the fixation component 100 (with less expansion and contraction) provides stable basic support, ensuring the wrist position is fixed; while the area farther from the fixation component 100 (with greater expansion and contraction) extends more significantly after inflation, applying more pronounced downward pressure to the palm and fingers, thereby causing the wrist to naturally bulge and actively exposing the radial artery puncture area. The combination of these two elements not only adjusts hand posture through the elastic deformation of the balloon but also works in conjunction with the fixation component 100 to restrict hand movement, reducing limb tremors caused by tension or pain, providing a stable and clear field of vision and positioning benchmark for the puncture procedure, effectively improving puncture efficiency and reducing operational difficulty.

[0041] Simultaneously, the balloon 212 expands gradually along the second direction (Y) from the side closer to the fixation component 100 to the side farther from the fixation component 100, while its expansion along the first direction (X) gradually increases, forming a gradient deformation characteristic with a small expansion amplitude at the proximal end (fixation component side) and a large expansion amplitude at the distal end. This change provides a larger angle adjustment space for the rotating component 221 in the puncture guidance mechanism 220. Based on the three-dimensional structure after the wrist bulge, the rotating component 221 can adjust the insertion angle of the puncture needle within a wider range, which can adapt to the individual anatomical differences of the radial artery in different patients and meet the clinical needs for diverse puncture techniques such as oblique and straight punctures. Compared with the traditional planar fixation method, the gradient expansion balloon 212 significantly enhances the adaptability of the device to complex puncture scenarios by actively shaping the anatomical shape of the wrist, reducing the problem of repeated punctures caused by angle limitations, and improving operational flexibility and success rate.

[0042] Optional, such as Figure 1 and Figure 2 As shown, the rotating component 222 has a second groove 2221 along the second direction (Y); the second groove 2221 has elongated first through holes 2222 on the side walls on both sides of the third direction (Z); the first through holes 2222 are symmetrically arranged along the bottom wall of the second groove 2221 on the central axis of the third direction (Z), and the first through holes 2222 are slidably connected to the piercing component 223.

[0043] Specifically, the rotating component 222 has a second groove 2221 along the second direction (Y). This second groove 2221 is used to accommodate the piercing component 223. The shape of the second groove 2221 matches the shape of the rotating component 222. The specific shape of the second groove 2221 is not limited in this embodiment. The second groove 2221 has elongated first through holes 2222 on its sidewalls along the third direction (Z). The two first through holes 2222 are symmetrically arranged along the bottom wall of the second groove 2221 on the central axis of the third direction (Z). The extending direction of the first through holes 2222 is parallel to the extending direction of the second groove 2221. The piercing component 223 includes a connecting portion that mates with the first through hole 2222. This connecting portion passes through the first through hole 2222 and is slidably connected to the first through hole 2222. Understandably, in some embodiments, the first through hole 2222 may also be configured as a groove that does not penetrate the rotating component 222, and the piercing component 223 includes a protrusion that mates with the groove, the protrusion being accommodated in the groove and slidably connected to the groove.

[0044] Understandably, the second groove 2221 and the elongated first through holes 2222 on both sides of the rotating component 222 provide a sliding guide structure for the puncture component 223. The symmetrical through hole design along the central axis ensures the balance and stability of the puncture component 223 during sliding. The puncture component 223 can be flexibly adjusted in the second direction (Y) along the through hole to adapt to the individual differences in the radial artery position of different patients, so that the placement angle and depth of the puncture needle can be accurately aligned with the target puncture point. The guiding effect of the elongated through hole can limit the deviation of the puncture component 223. Combined with the support structure of the groove, it effectively reduces the positional deviation caused by hand tremors or operating force during puncture, providing a stable guide path for the puncture needle, thereby improving the accuracy and success rate of puncture operation and reducing the risk of patient discomfort and tissue damage caused by repeated adjustments.

[0045] Optional, such as Figure 3 As shown, the puncture component 223 includes a first pressure plate 2231 and a second pressure plate 2232; the first pressure plate 2231 and the second pressure plate 2232 are rotatably connected at one end along the second direction (Y), and the rotatably connected end of the first pressure plate 2231 and the second pressure plate 2232 is away from the end of the airbag 212 with a smaller amount of extension and retraction in the second direction (Y); a fourth groove 2233 is provided at the end of the first pressure plate 2231 and / or the second pressure plate 2232 away from the end of the first pressure plate 2231 and the second pressure plate 2232 connected in the second direction (Y), and the fourth groove 2233 is used to place the puncture needle.

[0046] Specifically, the puncture component 223 includes a first pressure plate 2231 and a second pressure plate 2232. The first pressure plate 2231 and the second pressure plate 2232 can be cuboid structures or two semi-cylindrical structures that can cooperate with each other. This application embodiment does not limit their specific shapes. The ends of the first pressure plate 2231 and the second pressure plate 2232 away from the first airbag 210 with a smaller amount of extension are rotatably connected. The first pressure plate 2231 and the second pressure plate 2232 can be rotatably pressed together to fix the puncture needle. The rotatable connection of the first pressure plate 2231 and the second pressure plate 2232 can be connected by a hinge or a pin, etc. This application embodiment does not limit them. A fourth groove 2233 is provided at the end of the first pressure plate 2231 and / or the second pressure plate 2232 away from the connection between the first pressure plate 2231 and the second pressure plate 2232, and the puncture needle is placed in the fourth groove 2233.

[0047] In use, place the puncture needle in the fourth groove 2233, and rotate the second pressure plate 2232 to press the first pressure plate 2231 and the second pressure plate 2232 together to fix the puncture needle.

[0048] Understandably, the puncture component 223 employs a structural design where the first pressure plate 2231 and the second pressure plate 2232 are rotatably connected, allowing for flexible opening and closing. This facilitates quick and convenient placement of the puncture needle into the fourth groove 2233 by medical personnel. Simultaneously, the fourth groove 2233 formed by the first pressure plate 2231 and / or the second pressure plate 2232 provides a stable clamping effect on the puncture needle, limiting its displacement and movement before puncture and ensuring precise alignment of the puncture needle with the target position. Furthermore, this structural design is adaptable to puncture needles of different sizes. By adjusting the opening degree of the pressure plates and the position of the grooves, the device's adaptability to various puncture scenarios is enhanced, improving the success rate and safety of puncture operations.

[0049] Optional, such as Figure 3 As shown, the first pressure plate 2231 includes at least two first connectors 22311 arranged opposite each other along a third direction (Z). The first connectors 22311 are arranged opposite to the first through hole 2222 and are slidably connected to the elongated first through hole 2222.

[0050] Specifically, the puncture component 223 is provided with at least two first connectors 22311 along the third direction (Z). The first connectors 22311 are disposed opposite to the first through hole 2222 so that they can be inserted into the first through hole 2222 to slide the puncture component 223 and the rotating component 222. The first connector 22311 can be a rectangular block, a cylindrical pin, etc. extending along the third direction (Z), as long as it can be inserted into the rotating component 222 and slide connected with the rotating component 222. The specific shape is not limited in this embodiment. In some embodiments, there are two first connectors 22311, which are disposed opposite to each other along the third direction (Z) and inserted into the first through hole 2222 to achieve a sliding connection between the puncture component 223 and the rotating component 222. In some other embodiments, there are four first connectors 22311, wherein two first connectors 22311 are respectively provided on the two side walls of the first pressure plate 2231 along the second direction (Y), and the connectors on the two side walls are arranged opposite each other along the third direction (Z). All four first connectors 22311 are inserted into the first through hole 2222 to make the connection between the piercing component 223 and the rotating component 222 more stable.

[0051] Understandably, the first pressure plate 2231, through at least two first connectors 22311 arranged opposite each other along the third direction (Z) and slidingly engaging with the elongated first through hole 2222, provides a stable and precise guiding structure for the puncture component 223. The design of multiple connectors distributes the force during the puncture process, effectively avoiding deviation or wobbling caused by single-point force, ensuring the puncture needle slides smoothly along the preset path. The engagement of the elongated through hole with the connectors restricts the degree of freedom of the first pressure plate 2231 in the second direction (Y), allowing it to slide only in the direction required for puncture, reducing positional deviations caused by misoperation or external interference. Simultaneously, this structure allows medical personnel to flexibly adjust the position of the puncture component 223 according to the actual position of the patient's radial artery, improving the adaptability and accuracy of the puncture operation, reducing the risk of puncture failure, and providing reliable assurance for efficient and safe radial artery puncture.

[0052] Optional, such as Figure 1 As shown, the fixing assembly 100 further includes: a first fixing component 110, a second fixing component 120, and a third fixing component 130; the first fixing component 110 is connected to the second fixing component 120 at one end along the second direction (Y) near the first airbag 210, and the second fixing component 120 is rotatably connected to the third fixing component 130 at one end along the second direction (Y) away from the first fixing component 110; the first airbag 210 is connected to the second fixing component 120; the third fixing component 130 is rotatable along the end where the second fixing component 120 and the third fixing component 130 are connected.

[0053] Specifically, the fixing assembly 100 further includes a first fixing component 110, a second fixing component 120, and a third fixing component 130. The first fixing component 110 extends along a second direction (Y), and its end along the second direction (Y) near the first airbag 210 is connected to the second fixing component 120. The second fixing component 120 also extends along the second direction (Y), and its end along the second direction (Y) away from the first fixing component 110 is connected to the third fixing component 130, i.e., along the second direction (Y), the second fixing component 120 is located between the first fixing component 110 and the third fixing component 130. The second fixing component 120 is connected to the side of the first airbag 210 near the side with the smaller expansion and contraction of the airbag pouch 212. The third fixing component 130 is rotatable along the end where the second fixing component 120 and the third fixing component 130 are connected. The third fixing component 130 and the second fixing component 120 can be connected by a hinge or a pin; this embodiment does not limit the manner of their rotatable connection.

[0054] In use, the patient's arm is fixed to the first fixation component 110, the patient's wrist is fixed to the second fixation component 120, and the patient's palm is fixed to the third fixation component 130. Rotating the third fixation component 130 presses the patient's palm downwards along a third direction (Z), causing the wrist, which is fixed to the second fixation component 120, to bulge, thereby fully exposing the radial artery. This provides medical personnel with a clear puncture field and a stable puncture angle, facilitating a smooth puncture procedure.

[0055] In some embodiments, the first fixing member 110, the second fixing member 120, and the third fixing member 130 are each provided with at least one tightening strap 400 on their sides along the second direction (Y). The tightening strap 400 can be Velcro, elastic band, etc., and this application embodiment does not limit its application. The patient's forearm, wrist, and palm can be fixed to the first fixing member 110, the second fixing member 120, and the third fixing member 130 respectively by the tightening strap 400. Specifically, the patient can insert their palm between the third fixing member 130 and the first airbag 210, and the tightening strap 400 on the third fixing member 130 can fix the patient's palm between the first airbag 210 and the third fixing member 130 by the first airbag 210. In other embodiments, the tightening strap 400 on the third fixing member 130 can be elastic Velcro, allowing the patient's palm to move slightly and preventing stiffness during the procedure. The binding strap 400 on the second fixation component 120 can be a high-strength fiber Velcro to securely bind the patient's wrist to the second fixation component 120, preventing wrist movement from affecting the puncture.

[0056] Understandably, the fixation component 100 achieves segmented and precise fixation of the arm, wrist, and palm through the hierarchical connection of the first, second, and third fixation components. The connection between the first fixation component 110 and the second fixation component 120 provides stable basic support for the arm and wrist, while the rotational connection between the second fixation component 120 and the third fixation component 130, combined with the rotational function of the third fixation component 130, allows for active adjustment of the wrist posture by pressing down on the palm, causing it to naturally bulge and effectively exposing the radial artery puncture area. This combined structure not only improves the stability and flexibility of fixation but also reduces the difficulty of puncture operations for medical personnel, minimizes time losses caused by repeated adjustments, and provides a reliable guarantee for efficient and safe radial artery puncture.

[0057] Optional, such as Figure 1 As shown, the first fixation component 110 includes a first fixation member 111, a first support member 112, and a second connector 113; one end of the second connector 113 is connected to the first fixation member 111, and the other end is connected to the second fixation component 120; the first support member 112 is disposed on the first fixation member 111 and is on the same side as the first airbag 210 along the third direction (Z), and the first support member 112 is used to place the patient's forearm.

[0058] Specifically, the first fixing component 110 includes a first fixing member 111, a first supporting member 112, and a second connecting member 113. The first fixing member 111 can be a rigid plastic plate or a steel plate, and this embodiment does not limit its use. The first fixing member 111 is used to fix the first supporting member 112 and provide effective support force for the first supporting member 112. The first fixing member 111 can be connected to the first supporting member 112 by bolts or adhesive materials, and this embodiment does not limit its use.

[0059] The first support member 112 is disposed on the same side as the first fixation member 111 along the first direction (X) and the first airbag 210, and the first support member 112 is used to support the patient's arm. In some embodiments, the first support member 112 may be an arc-shaped plate that bends along the first direction (X) from the side closer to the first fixation member 111 to the side away from the first fixation member 111, and the patient's forearm is placed in the recess of the arc-shaped plate to better fix the patient's arm. The first support member 112 may be made of rigid plastic or steel plate, and the embodiments of this application do not limit it. It is understood that the first support member 112 may also be covered with soft materials such as sponge or fabric to make the patient more comfortable.

[0060] The second connector 113 is connected at one end along the second direction (Y) to the first fixing member 111, and at the other end to the second fixing member 120, so that the first fixing member 110 and the second fixing member 120 are stably connected. In some embodiments, the second connector 113 may be provided with at least one slide rail along the second direction (Y), and the second fixing member 120 is provided with a slider that cooperates with the slide rail, so that the second fixing member 120 slides along the slide rail to adjust the distance between the first fixing member 110 and the second fixing member 120 to adapt to the forearm length of different patients.

[0061] Understandably, the first fixation component 110 employs a combination design of a first fixator 111, a first support 112, and a second connector 113, providing a stable and comfortable support and fixation solution for the patient's forearm. The second connector 113 ensures a reliable connection between the first fixation component 110 and the second fixation component 120, guaranteeing the structural continuity and stability of the entire fixation assembly 100. Simultaneously, this structure effectively limits forearm movement, and in conjunction with the first airbag 210 and other fixation components 221, forms a multi-layered, stable support for the hand from the arm to the wrist and palm, providing a stable foundation for radial artery puncture, reducing puncture deviation caused by patient limb movement, and improving the success rate and safety of the puncture procedure.

[0062] Optional, such as Figure 1As shown, the second fixing component 120 includes a second fixing member 112 and a second airbag 122; the second fixing member 112 is connected to the second connecting member 113, the second airbag 122 is disposed on the second fixing member 112 and is on the same side as the first supporting member 112; the second airbag 122 is connected to the first airbag 210; the second airbag 122 is used to place the patient's wrist.

[0063] Specifically, the second fixing component 120 includes a second fixing member 112 and a second airbag 122. One end of the second fixing member 112, located away from the third fixing component 130 along the second direction (Y), is connected to the second connecting member 113. The second fixing member 112 can be a rigid plastic plate or a steel plate; this embodiment does not limit its application. The second fixing member 112 is used to fix the second airbag 122 and provide effective support for the second airbag 122. The second fixing member 112 can be connected to the second airbag 122 through an adhesive substance or the like; this embodiment does not limit its application.

[0064] The second airbag 122 is disposed on the same side of the second fixing member 112 along the first direction (X) and the first support member 112, and the second airbag 122 is used to support the patient's wrist. In some embodiments, the second airbag 122 can be a saddle-shaped airbag, the curved surface of which is disposed away from the second fixing member 112 along the first direction (X), and the saddle-shaped curved surface extends along the second direction (Y) so that the patient's wrist can be placed in the curved recess of the saddle-shaped airbag. After the second airbag 122 is inflated, it expands along the first direction (X) away from the second fixing member 112 to elevate the patient's wrist along the first direction (X). The second airbag 122 is connected to the first airbag 210. In some embodiments, the second airbag 122 and the first airbag 210 are connected through an air tube. The second airbag 122 also includes a miniature air pump, which can inflate the first airbag 210 and the second airbag 122 simultaneously during inflation. In other embodiments, the second airbag 122 and the first airbag 210 are each equipped with a miniature air pump. Medical personnel can control the inflation volume of the first airbag 210 and the second airbag 122 respectively according to specific needs. The first airbag 210 is connected to the second airbag 122 only through a connecting tube. The miniature air pump can be a manually controlled inflation pump or an electrically controlled inflation pump, and the embodiments of this application do not limit it.

[0065] Understandably, the second fixation component 120, through the combined design of the second fixation member 112 and the second airbag 122, provides a flexible yet stable fixation method for the patient's wrist. The second fixation member 112 is connected to the first fixation component 110 via the second connector 113, ensuring the overall structural strength and stability of the fixation assembly 100. The second airbag 122, positioned on the second fixation member 112 and on the same side as the first support member 112, can precisely conform to the contour of the patient's wrist. The uniform pressure generated after inflation can both tightly fix the wrist, preventing displacement during puncture, and avoid the discomfort caused by rigid fixation, thus improving patient cooperation. Simultaneously, the second airbag 122 is connected to the first airbag 210, achieving coordinated pressure control between the two. While fixing the patient's hand, the fixation force can be flexibly adjusted according to actual needs, further enhancing the stability of the fixation effect. Furthermore, this design can effectively distribute the pressure on the hand during puncture, reducing the patient's wrist pressure and fatigue, providing a stable and comfortable operating environment for radial artery puncture, thereby improving the success rate and safety of the puncture operation.

[0066] Optional, such as Figure 1 As shown, the second fixing component 120 includes at least two binding straps 300, which are arranged opposite each other in a third direction (Z); the binding straps 300 include at least one hemostatic part, which corresponds to the location of the radial artery puncture point of the patient and is used to place the hemostatic device.

[0067] Specifically, the second fixing component 120 has at least one tightening strap 300 on each side along the second direction (Y), and the two tightening straps on the sides are arranged opposite each other along the third direction (Z), allowing the user to fix the patient's wrist and the second fixing component 120. The tightening strap 300 can be Velcro or elastic band, and this embodiment does not limit it. The tightening strap 300 also includes at least one hemostatic part, which is opposite to the radial artery puncture point of the patient. A hemostatic item such as a cotton ball can be placed on the hemostatic part. After the patient completes the radial artery puncture, a hemostatic item can be placed on the hemostatic part, and the tightening strap 300 can be wrapped around the patient's wrist so that the hemostatic part fits against the patient's puncture wound. The tightening strap 300 is then tightened, applying pressure to the patient's wound, thereby achieving effective hemostasis of the patient's wound.

[0068] In some embodiments, a timing alarm device is also provided at the second airbag 122. After medical staff complete the radial artery puncture and use a bandage to wrap around the patient's wrist to precisely apply pressure to the wound for hemostasis, the countdown timer of the timing alarm device can be set according to clinical needs. After the device is activated, the remaining time is displayed in real time in digital form. When the timer ends, a reminder signal will be issued through a dual-mode sound and light. For example, a buzzer alarm will be sounded accompanied by flashing lights to promptly inform medical staff that the pressure hemostasis process has been completed. At this time, the puncture device can be safely removed, avoiding insufficient or excessive hemostasis time due to human error in timing, and effectively improving the standardization and safety of postoperative care.

[0069] Understandably, the second fixation component 120, by setting at least two tightening straps 300 positioned opposite each other along a third direction (Z), can form a circumferential fixation around the patient's wrist from both sides. Compared to unilateral fixation, this effectively disperses pressure, avoids localized pressure discomfort, and provides a more stable restraint effect, preventing wrist displacement or movement during puncture. The hemostatic portion on the tightening strap 300 precisely corresponds to the patient's radial artery puncture point, allowing medical staff to directly place cotton balls or other hemostatic devices on the hemostatic portion after puncture without additional position adjustments or manual pressure. Simply tightening the tightening strap 300 quickly applies pressure to the wound to achieve hemostasis. This integrated design combines fixation and hemostasis functions, simplifying the procedure, saving time, and reducing the risk of bleeding due to delayed hemostasis or positional errors, thus improving the convenience and safety of post-radial artery puncture care.

[0070] In some embodiments, a high-precision pressure sensor is integrated on the surface of the second airbag 122 and / or the first airbag 210, and this sensor is electrically connected to the airbag pump. During puncture and fixation, the pressure sensor continuously collects real-time pressure data of the contact area between the airbag and the patient's wrist and / or palm, and transmits the information synchronously to the air pump control system. Once pressure fluctuations caused by the patient's limb micro-movements, muscle contractions, etc., are detected, the air pump will automatically adjust the inflation volume according to a preset pressure threshold: quickly replenishing air when the pressure is insufficient, and precisely deflating air when the pressure is too high, maintaining stable fixation of the airbag to the patient's hand through a dynamic pressure compensation mechanism. Compared with traditional airbag devices, this intelligent feedback system can effectively counteract the influence of the patient's unconscious limb movements, ensure the stability of the puncture point position, and significantly reduce the risk of puncture failure due to fixation failure.

[0071] In some embodiments, the radial artery puncture device has a standardized universal interface at its rear end. This interface adopts a modular plug-and-play design, supporting plug-and-play functionality. After the patient completes the puncture and initial hemostasis, medical staff can quickly connect the blood oxygen monitoring module to the device through the standardized interface according to clinical needs. The blood oxygen monitoring module collects data such as blood oxygen saturation and blood perfusion index at the puncture site in real time and displays the information synchronously on the device's integrated display screen. Medical staff can intuitively observe the patient's postoperative recovery status and promptly detect abnormalities such as local ischemia caused by improper hemostasis. The device is also compatible with the connection of an automatic compression robot. When the blood oxygen monitoring module detects abnormalities such as poor hemostasis or bleeding at the puncture site, the system will automatically trigger the connected automatic compression robot. The robot receives control commands through the standardized interface and adjusts the compression force and position according to a preset program to provide precise and continuous pressure hemostasis at the puncture site, eliminating the need for frequent manual intervention by medical staff. For example, in nighttime nursing scenarios, the system can achieve 24 / 7 automated monitoring and treatment, effectively reducing the workload of medical staff while improving the timeliness and safety of postoperative care.
