Description

Technical Field

[0001] This invention relates to the field of arterial blood collection technology, and in particular to an intelligent sensing arterial blood collection auxiliary device. Background Technology

[0002] Current clinical arterial blood sampling (such as radial artery sampling) still relies on traditional manual operation methods, which have several technical drawbacks. First, arterial positioning is highly dependent on the "feel" and visual judgment of medical staff, which is highly subjective. For thinner blood vessels, deeper locations (such as the radial artery), or obese, edematous, or weakly pulsating patients (such as elderly patients or patients in shock), positioning errors are prone to occur, leading to repeated punctures. This not only increases patient pain but also easily causes complications such as vascular damage, local hematoma, and pseudoaneurysm. For patients with poor coagulation function such as liver disease or those undergoing chemotherapy, the risk of bleeding is significantly increased.

[0003] Secondly, the operation process is cumbersome and inefficient: after positioning, the puncture point needs to be manually marked, and then disinfected separately with an iodine bottle. The steps are scattered, and each blood collection takes a long time, which is not suitable for "time-sensitive" scenarios such as emergency rooms and ICUs. Moreover, manually applying iodine can easily lead to dosage loss - too much dosage can easily contaminate clothing, while too little will not disinfect thoroughly and may pose a risk of infection. Summary of the Invention

[0004] Given the problems of existing technologies, such as arterial positioning relying on touch and vision which is prone to deviation leading to repeated punctures, cumbersome operation procedures (requiring manual marking and disinfection), and difficulty in controlling the dosage of iodine, an intelligent sensing arterial blood collection auxiliary device is proposed.

[0005] Its purpose is to: replace subjective judgment with data-driven positioning, improve the accuracy of positioning for special populations, and reduce repeated punctures and pain; integrate functions to achieve automatic disinfection and simplify the process to adapt to emergency departments; use flexible volume control of sealed bottles to prevent waste and ensure disinfection effect; and ultimately lower the threshold for medical staff and improve the accuracy, safety and efficiency of blood collection.

[0006] The technical solution of the present invention is an intelligent sensing arterial blood collection auxiliary device, including a test pad, a plurality of sensing modules arranged in a linear array within the test pad, and an iodine-labeling module disposed within the sensing modules; The sensing module includes a mounting hole opened in the test pad and a pressure sensor disposed in the mounting hole; The iodine marking module includes an unfolding component disposed on one side of the mounting hole, an iodine bottle disposed within the unfolding component, the iodine bottle being made of soft plastic material, and two liquid dispensing components symmetrically disposed within the unfolding component. The unfolding assembly includes a folding groove on the side wall of the mounting hole, two folding plates symmetrically arranged in the folding groove via a rotating rod, a torsion spring between the rotating rod and the test pad, an unfolding plate between the two folding plates, a compression plate at the bottom of the unfolding plate, a mounting groove in the middle of the unfolding plate matching the shape of an iodine bottle, and a marking hole on the compression plate that is connected to the bottom of the mounting groove. The dispensing component is used to squeeze the iodine bottle to mark the flow of iodine solution, facilitating subsequent direct puncture and blood draw.

[0007] Furthermore, one side of the iodine bottle does not protrude from the side of the unfolding plate.

[0008] Furthermore, positioning components are provided on both sides of the unfolding plate. The positioning components include rotating grooves respectively opened on the top two sides of the unfolding plate, a fixed rod set in the rotating groove and fixedly connected to the folding plate, a torsion spring II set in the fixed rod and the rotating groove, a rotating groove opened on the outside of the rotating groove, a stop block set in the rotating groove, and a stop block set on the side of the fixed rod near the folding plate. The stop block rotates in the rotating groove.

[0009] Furthermore, the liquid dispensing assembly includes a groove on one side of the fixed rod, an extrusion member disposed inside the unfolding plate, the extrusion member consisting of three round rods and a connecting plate, one of the round rods being located in the middle of the connecting plate, the other two round rods being symmetrically distributed at both ends of one side of the connecting plate, extrusion grooves on both sides of the mounting groove, a crossbar disposed in the extrusion groove, a liquid dispensing plate disposed on the crossbar, a torsion spring disposed between the liquid dispensing plate and the crossbar, pressure plates symmetrically disposed on both sides of the liquid dispensing plate, the tops of the two pressure plates respectively abutting against the round rods at the bottom of the extrusion member, and a reset assembly disposed on the top of the extrusion member.

[0010] Furthermore, the dispensing plate is in an arc shape that tilts towards the iodine bottle, and the two pressure plates are in an arc shape that is opposite to the tilting direction of the dispensing plate.

[0011] Furthermore, the reset assembly includes a reset plate disposed on the top round rod of the extruder, and a reset spring disposed at the bottom of the reset plate. The reset spring is sleeved on the top round rod of the extruder, and the bottom of the reset spring abuts against a round groove opened inside the unfolding plate.

[0012] Furthermore, when the torsion springs inside the folding plate and the unfolding plate are in their initial state, the two folding plates and the unfolding plate unfold naturally. At this time, the abutment block is below the stop block, and there is still room for rotation between the abutment block and the stop block.

[0013] Furthermore, when the two folding plates and the unfolding plate are naturally unfolded, the extrusion plate maintains a tilt angle of 5-10 degrees with the horizontal plane.

[0014] Furthermore, the pressure sensor has an indicator light on its top, and its top two sides are inclined and have strip-shaped grooves respectively. The bottom two sides of the pressure sensor have connecting blocks respectively, and two positioning grooves are opened on both sides of the mounting hole. The connecting blocks slide in the positioning grooves, and the bottom of the pressure sensor is pressed and adhered to the skin.

[0015] Furthermore, the test pad is in an arc shape that conforms to the skin, and its material is soft.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By relying on linear array pressure sensors and intelligent analyzers, arterial data positioning is achieved, replacing the subjective judgment of traditional touch and vision. This reduces repeated punctures for patients with thin blood vessels, deep locations (such as the radial artery), and edema, and reduces complications such as vascular injury and pseudoaneurysm. It can also reduce the risk of bleeding for liver disease patients with poor coagulation and chemotherapy patients, and significantly improve the positioning accuracy for people with weak pulsation and obesity.

[0017] 2. Deeply integrates positioning, marking, and disinfection functions. The unfolding components automatically unfold to form a triangular support by means of a torsion spring, eliminating the need for manual assembly. This achieves an integrated operation of automatic disinfection and marking upon sensor retrieval, shortening the time required for a single blood collection. The process can be completed with one hand, making it suitable for efficient scenarios such as emergency rooms and ICUs where rapid blood collection is required. It is especially convenient for stabilizing pediatric patients and agitated patients.

[0018] 3. The sealed iodine bottle and the torsion spring three-elastic compression structure allow for precise dosage control, avoiding dosage loss due to manual application (preventing waste and incomplete disinfection). The torsion spring three can also adapt to bottle shrinkage to reduce residual liquid. The soft arc-shaped test pad adapts to different hand shapes, simplifying operation and reducing the learning cost for medical staff. New employees can get started quickly, balancing blood collection safety and iodine utilization. Attached Figure Description

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figures 1-10This is the first embodiment of the present invention, which provides an intelligent sensing arterial blood collection auxiliary device, including a test pad 1, a plurality of sensing modules arranged in a linear array within the test pad 1, and an iodine marking module disposed within the sensing modules; the sensing modules include mounting holes 11 opened in the test pad 1, and pressure sensors 12 disposed within the mounting holes 11; the pressure sensors 12 are 29mm×29mm×31mm in size, approximately the size of a soybean, a power supply component installed inside one end of the test pad 1, the power supply component including a power supply and internal power connection wires and other electronic components, and an intelligent analyzer installed inside the other end of the test pad 1, the power supply component being used to provide power to all pressure sensors 12 and the intelligent analyzer. During blood collection, all pressure sensors 12 send pressure data to the intelligent analyzer. After intelligent analysis, the intelligent analyzer sends an indicator light to the pressure sensor 12 with the strongest pressure data. At this time, the pressure sensor 12 with the strongest pressure lights up. Then, the medical staff uses a clamp to remove the pressure sensor 12 at this point. During the removal process, the iodine marking module automatically marks the puncture point with iodine. After marking, the pressure sensor 12 is put back in, and the test pad 1 is removed. At this time, the medical staff directly punctures and draws blood from the marked point. The iodine marking module includes an unfolding component 2 disposed on one side of the mounting hole 11, an iodine bottle placed inside the unfolding component 2 (the iodine bottle is made of soft plastic and is relatively small in size), and two dispensing components 4 symmetrically disposed within the unfolding component 2. The unfolding component 2 includes a folding groove 21 formed on the side wall of the mounting hole 11, two folding plates 22 symmetrically disposed within the folding groove 21 via a rotating rod, a torsion spring abutting between the rotating rod and the test pad 1, an unfolding plate 23 rotatably connected between the two folding plates 22, a squeezing plate 24 fixedly connected to the bottom of the unfolding plate 23, a mounting groove 25 in the middle of the unfolding plate 23 matching the shape of the iodine bottle, and a marking hole 26 on the squeezing plate 24 that communicates with the bottom of the mounting groove 25. The dispensing components 4 are used to squeeze the iodine bottle to mark the flow of iodine solution, facilitating subsequent direct puncture and blood collection.

[0023] Specifically, during testing, the entire device is moved to the blood collection position on the hand. Several sensing modules arrayed within the test pad 1 detect and identify the point of maximum pressure. At this time, the indicator light 6 of the pressure sensor 12 at the point of maximum pressure illuminates. The blood collection personnel remove the illuminated pressure sensor 12 using a clamp. The two folding plates 22 and the unfolding plate 23 automatically unfold under the reset action of the torsion spring, making the folding plates 22 and the unfolding plate 23 triangular, so that the squeezing plate 24 is parallel to the skin surface. The iodine bottle is confined within the mounting groove 25. When the unfolding plate 23 unfolds, it triggers the internal liquid dispensing component 4, causing the liquid dispensing components 4 on both sides to squeeze the soft material sidewall of the iodine bottle, thereby causing the iodine solution to flow out from the dispensing port and drip onto the puncture point surface through the marking hole 26. It should be noted that when the unfolding plate 23 unfolds naturally, the marking hole 26 moves to the position consistent with the detection point of the pressure sensor 12, ensuring that the iodine solution drips onto the detection point, that is, ensuring that the puncture point is also the detection point.

[0024] The device uses several sensing modules arranged in a linear array to cover a blood collection area of ​​2-3 cm (such as the commonly used blood collection segment of the radial artery). The pressure sensor 12 in each module synchronously captures the pressure signal of the arterial pulsation on the skin surface and transmits it to the intelligent control analyzer set inside the test pad 1. The analyzer compares and selects the point with the greatest pressure, that is, the point with the strongest arterial pulsation, so that the indicator light 6 of the pressure sensor 12 at the point with the strongest pressure lights up. This upgrades the positioning from relying on touch to data-driven positioning, improving the positioning accuracy for people with weak pulsation. The unfolding component 2 is designed with "folding groove 21, torsion spring and rotating rod". Blood collection personnel only need to take out the lit pressure sensor 12, and the two folding plates 22 will automatically unfold under the reset action of the torsion spring to form a triangular support structure. There is no need to manually pry open or assemble the positioning components. The operation can be completed with one hand, which is especially suitable for "time-sensitive" scenarios such as emergency rooms and ICUs, shortening the preparation time for a single positioning. Pressure data is collected in real time by a linear array of pressure sensors 12. The intelligent analyzer selects the point of strongest pressure (i.e., the artery location) and illuminates it to indicate the location. This avoids the subjective errors of traditional blood sampling, which relies on the "feel" and "visual" judgment of medical staff. It is especially suitable for patients with thinner blood vessels, deeper locations (such as the radial artery), or obese or edematous patients. It improves the accuracy of puncture positioning to the level of objective data-driven analysis, reducing repeated punctures due to inaccurate positioning. Precise positioning directly reduces the number of "trial punctures" and avoids complications such as vascular damage, local hematoma, and pseudoaneurysm caused by repeated punctures during arterial blood sampling. It can significantly reduce the risk of bleeding, especially for patients with poor coagulation function (such as patients with liver disease or undergoing chemotherapy).

[0025] Reference Figures 5-8 One side of the iodine bottle does not protrude from the side of the unfolding plate 23.

[0026] Specifically, this allows the pressure sensor 12 to smoothly press the inclined surface of the unfolding plate 23 when inserted, thereby enabling the unfolding plate 23 and the folding plate 22 to be folded and stored.

[0027] Example 2, refer to Figure 8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: positioning components 3 are also provided on both sides of the unfolding plate 23. The positioning components 3 include rotating grooves 31 respectively opened on the top two sides of the unfolding plate 23, a fixed rod 32 rotatably connected in the rotating groove 31, the fixed rod 32 being fixedly connected to the folding plate 22, a torsion spring 2 being abutted against the fixed rod 32 and the rotating groove 31, a rotating groove 33 opened on the outside of the rotating groove 31, a stop block 34 fixedly connected in the rotating groove 33, and a stop block 35 fixedly connected to the side of the fixed rod 32 near the folding plate 22, the stop block 35 rotating in the rotating groove 33.

[0028] Specifically, when the unfolding plate 23 rotates, the fixing rod 32 drives the abutment block 35 to rotate in the rotating groove 33. The torque of the first torsion spring is greater than that of the second torsion spring. When it unfolds naturally, the folding plate 22 continues to squeeze the unfolding plate 23, causing the unfolding plate 23 to push the squeezing plate 24 to move against the skin. Finally, the squeezing plate 24 is in contact with the skin surface, so that the marking hole 26 can be aligned with the detection point of the pressure sensor 12, and thus the iodine solution can be directly and accurately dripped into the puncture point.

[0029] Example 3, referring to Figures 9-10 This is the third embodiment of the present invention, which differs from the first embodiment in that: the liquid dispensing assembly 4 includes a groove 41 formed on one side of the fixed rod 32, an extrusion member 42 slidably connected inside the unfolding plate 23, the extrusion member 42 being composed of three round rods and a connecting plate, one of the round rods being located in the middle of the connecting plate, and the other two round rods being symmetrically distributed at both ends of one side of the connecting plate, extrusion grooves 44 formed on both sides of the mounting groove 25, a crossbar 45 fixedly connected in the extrusion grooves 44, a liquid dispensing plate 46 rotatably connected to the crossbar 45, a torsion spring 3 abutting between the liquid dispensing plate 46 and the crossbar 45, pressure plates 47 symmetrically fixedly connected on both sides of the liquid dispensing plate 46, the tops of the two pressure plates 47 abutting against the round rods at the bottom of the extrusion member 42 respectively, and a reset assembly 5 disposed on the top of the extrusion member 42.

[0030] Specifically, during the unfolding process of the unfolding plate 23 and the folding plate 22, the fixing rod 32 at the folding plate 22 rotates relative to each other in the rotating groove 31. Under the squeezing force of the reset component 5, one side of the squeezing member 42 automatically slides into the groove 41 from the periphery of the fixing rod 32. That is, the squeezing member 42 moves towards the folding plate 22 in the unfolding plate 23, so that the bottom of the squeezing plate 24 is released from the squeezing of the pressure plate 47. Under the torsion force of the torsion spring, the pressure plate 47 and the liquid outlet plate 46 squeeze one side of the liquid outlet plate 46 against both sides of the iodine bottle, thereby realizing the outflow of iodine from the iodine bottle. When the iodine bottle is inverted, since its interior is sealed, under the action of atmospheric pressure, the iodine liquid inside will not flow out actively without being squeezed. After the iodine solution flows out of the mark, the pressure sensor 12 is put back in, causing the unfolding plate 23 and the folding plate 22 to fold again. At this time, the fixing rod 32 rotates, squeezing the top of the squeezing member 42, causing the squeezing member 42 to compress the reset assembly 5. The two round rods at the bottom of the squeezing member 42 squeeze the pressure plate 47. The pressure plate 47 rotates, causing the liquid outlet plate 46 to rotate into the squeezing groove 44, detaching from the squeezing of the iodine bottle. As the amount of medicine in the iodine bottle decreases, the bottle body (soft plastic material) will shrink due to the reduced pressure. Traditional fixed-space squeezing structures are prone to problems such as "insufficient squeezing force in the later stage and inability to squeeze out residual liquid". However, the elastic characteristics of the torsion spring 3 can adjust the squeezing amplitude of the liquid outlet plate 46 in real time. When the bottle body is full, the slight deformation of the torsion spring 3 can provide sufficient pressure. When the bottle body shrinks, the torsion spring 3 pushes the liquid outlet plate 46 closer to the bottle body through greater deformation, always maintaining effective squeezing force, significantly improving the utilization rate of medicine and reducing the frequency of frequent replacement of iodine bottles.

[0031] Reference Figures 9-10 The dispensing plate 46 is in an arc shape that tilts towards the iodine bottle, and the two pressure plates 47 are in an arc shape that is opposite to the tilting direction of the dispensing plate 46.

[0032] Specifically, the arc-shaped design of the dispensing plate 46 facilitates the dispensing of liquid by squeezing, and the arc-shaped design of the pressure plate 47 facilitates the dispensing plate 46 to reverse and retract when squeezed. When there is very little liquid in the iodine bottle, that is, when the rotation angle of the dispensing plate 46 is large, the round rod at the bottom of the squeezing member 42 can still squeeze the pressure plate 47, thereby causing the dispensing plate 46 to reverse and retract.

[0033] Reference Figures 9-10 The reset assembly 5 includes a reset plate 51 fixedly connected to the top round rod of the extruder 42, and a reset spring 52 abutting against the bottom of the reset plate 51. The reset spring 52 is sleeved on the top round rod of the extruder 42, and the bottom of the reset spring 52 abuts against the round groove opened inside the unfolding plate 23.

[0034] Specifically, when the unfolding plate 23 is in the folded state, the squeezing member 42 is squeezed by the periphery of the fixing rod 32, and the return spring 52 is compressed by the return plate 51, so that the bottom of the squeezing member 42 squeezes the pressure plate 47, preventing the iodine bottle from being squeezed out of the liquid, causing the iodine solution to flow out, resulting in pollution and waste.

[0035] Reference Figure 8 When the torsion springs in the folding plate 22 and the unfolding plate 23 are in their initial state, the two folding plates 22 and the unfolding plate 23 unfold naturally. At this time, the abutment block 35 is below the stop block 34, and there is still room for rotation between the abutment block 35 and the stop block 34.

[0036] Specifically, this design allows the folding plate 22 to continuously squeeze and rotate the unfolding plate 23 under the force of the torsion spring when the folding plate 22 and the unfolding plate 23 are naturally unfolded. This allows the unfolding plate 23 to drive the squeezing plate 24 to fit against the skin surface and to align the marking hole 26 with the detection point, thereby making the detection point correspond to the puncture point and improving the accuracy of puncture.

[0037] Reference Figure 8 When the two folding plates 22 and the unfolding plate 23 are naturally unfolded, the pressing plate 24 maintains an inclination angle of 5-10 degrees with the horizontal plane.

[0038] Specifically, as described above, this facilitates the compression plate 24 to eventually adhere to the skin surface under the combined rotation and movement, and also facilitates the expansion plate 23 to be compressed and contracted.

[0039] Reference Figures 1-4 The pressure sensor 12 has an indicator light 6 installed on its top. The top two sides are inclined and have strip grooves 41 respectively. The bottom two sides of the pressure sensor 12 are fixedly connected to the connecting blocks 7 respectively. The mounting hole 11 has two positioning grooves 8 respectively. The connecting blocks 7 are slidably connected in the positioning grooves 8. The connecting blocks 7 are made of conductive metal. The groove wall of the positioning groove 8 is provided with a metal connecting piece for conducting electricity with the connecting blocks 7. The bottom of the pressure sensor 12 is pressed and adhered to the skin.

[0040] Specifically, indicator light 6 is used to indicate the point where the pulse pressure detected by medical staff is the maximum, so that the pressure sensor 12 can be taken out by clamping the strip grooves 41 on both sides with the clamp. The installation and removal are done in the same way. The design of connecting block 7 and positioning groove 8 not only facilitates the installation of pressure sensor 12, but also allows the pressure sensor 12 to be powered through the contact between connecting block 7 and positioning groove 8, so that pressure sensor 12 can sense pulse pressure.

[0041] Reference Figures 1-3 The test pad 1 is in the shape of an arc that conforms to the skin, which helps to improve the detection accuracy of the pressure sensor 12. Its material is soft.

[0042] Specifically, when the pressure sensor 12 is placed back in, the bottom edge of the pressure sensor 12 will press against the edges of the unfolding plate 23 and the pressing plate 24, thereby causing the unfolding plate 23 and the folding plate 22 to fold and be stored in the folding groove 21, completing the storage. One side of the folding groove 21 is inclined, and the unfolding component 2 can be completely stored in it. The rest of the structure is the same as the structure of the embodiment.

[0043] Based on embodiments 1-3, the working principle of this invention is as follows: The device is based on a soft arc-shaped test pad 1, and incorporates a linear array sensing module, a power supply component, and an intelligent analyzer, working in conjunction with an iodine marking module. During blood collection, the test pad 1 is first placed against the area of ​​the hand to be circulated. The power supply component powers the pressure sensor 12 and the analyzer. The sensor synchronously collects arterial pulsation pressure data and transmits it to the analyzer. The analyzer selects the point of strongest pressure (the point of strongest arterial pulsation), triggering the corresponding indicator light 6 on the top of the sensor to illuminate. Medical personnel use the strip grooves 41 on both sides of the sensor to clamp out the illuminated sensor. The folding plate 22 and the unfolding plate 23 automatically unfold into a triangular shape under the action of the torsion spring 1. Due to the greater torque of the torsion spring 1, the positioning component 3 pushes the unfolding plate 23, causing the squeezing plate 24 to adhere to the skin, so that the marking hole 26 is accurately aligned with the pressure detection point. At the same time, the fixing rod 32 rotates, allowing the squeezing component 42 to slide into its groove 41, detaching from the pressure plate 47. The torsion spring 3 drives the arc-shaped liquid outlet plate 46 to squeeze and seal the iodine bottle, and the iodine is dripped into the puncture point through the marking hole 26. After marking, the pressure sensor 12 is returned to its original position. The bottom of the sensor is then pressed to reposition the unfolded plate 23 and folded plate 22. The fixing rod 32 presses against the extrusion component 42, compressing the reset assembly 5. The bottom round rod of the extrusion component 42 pushes the reverse arc-shaped pressure plate 47, causing the liquid outlet plate 46 to retract and stop the liquid flow. Finally, the test pad 1 is removed, and medical staff directly puncture the marked point. The entire process achieves "data-driven positioning - automatic marking - precise reset." The pressure sensor 12 connecting block 7 and positioning groove 8 also provide electrical power and easy disassembly, improving detection accuracy and operational efficiency.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
