Technical Field

[0001] The invention relates to the technical field of carotid pulse measurement, in particular to an automatic carotid artery stenosis measurement device which is convenient for adjusting the inner diameter. Background Art

[0002] Medical science has long sought to accurately measure the physiological parameters of living objects. One particularly important area is the non-invasive continuous measurement of blood pressure or other hemodynamic parameters. The carotid artery is an artery present in the neck of vertebrates, located on both sides of the trachea in the neck. It is a shallow artery on the body surface and its pulsation can be felt by hand. The pulsation of the carotid artery in normal people is not easy to see at rest. During strenuous activities, the heart output increases and a weak pulsation of the carotid artery can be seen. The carotid artery pulsation test is an auxiliary examination method used to check whether the carotid artery is normal. The periodic fluctuation of the wall of the carotid artery in each cardiac cycle. In the resting state, the carotid artery has obvious pulsation, which is seen in patients with aortic valve insufficiency, hypertension, hyperthyroidism and severe anemia. Weakened or absent carotid artery pulsation may be caused by polyarteritis.

[0003] Chinese patent CN219480082U discloses an automatic measurement device for carotid artery stenosis, including a neck strap, two blood flow sensors arranged on the neck strap, two acoustic sensors arranged on the neck strap, and a processor; the neck strap is used to be put on the neck of a human body; the two blood flow sensors are used to collect blood flow velocity data of the carotid arteries on both sides of the human neck; the two acoustic sensors are used to collect sound data of the carotid arteries on both sides of the human neck; the processor is used to receive the blood flow velocity data collected by the two blood flow sensors and the sound data collected by the two acoustic sensors, and judge whether there is carotid artery stenosis according to the blood flow velocity data and the sound data. The utility model can automatically perform carotid artery stenosis inspection, the inspection is convenient, fast, economical and affordable, and can be used for screening of carotid artery stenosis in large-scale populations in the community.

[0004] When the automatic carotid stenosis measuring device is used to check the carotid pulse, the neck strap needs to be worn on the patient's neck, and the detection area on the neck strap needs to be aligned with the carotid artery on the affected side. Different patients have different body shapes and different neck circumferences. Due to the different neck circumferences of the patients, when adjusting the inner diameter of the neck strap, the detection area cannot be aligned with the patient's carotid artery, resulting in poor and inaccurate detection and measurement results. In addition, since the carotid arteries are located on both sides of the trachea in the human neck, tightening the neck strap when wearing the detection device will cause the patient to have difficulty breathing and feel uncomfortable. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides an automatic measuring device for carotid stenosis that is easy to adjust the inner diameter. The device is provided with a tensioning adjustment part to adjust the front neck strap in front of the patient's neck, so that the middle part of the front neck strap is closer to the patient's neck, thereby enabling the detection component to be closely attached to the patient's carotid vein. The front neck strap will not be bound by the patient's trachea, resulting in the tightening of the front neck strap causing the patient to have difficulty breathing, feel uncomfortable, and other problems. The device solves the problem that due to the different neck circumferences of patients, when adjusting the inner diameter of the neck strap, the detection area cannot be aligned with the patient's carotid artery, thus causing poor and inaccurate detection and measurement effects. Moreover, since the carotid arteries are located on both sides of the trachea in the human neck, when wearing the detection device, the tightening of the neck strap will cause the patient to have difficulty breathing, feel uncomfortable, and other problems. Moreover, if the bilateral carotid arteries are compressed at the same time, the patient will feel uncomfortable, especially for patients with severe stenosis of the blood vessels. If they are compressed at the same time, there is a risk of inducing cerebral ischemia.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides an automatic measuring device for carotid artery stenosis that is convenient for adjusting the inner diameter, and has the following beneficial effects:

[0019] 1. The automatic measuring device for carotid stenosis, which is easy to adjust the inner diameter, is placed behind the patient's carotid artery through the support suction cup in the carotid artery detection component, and cooperates with the inflated support airbag to make the detection component inside the support airbag face and close to the carotid artery; the back adjustment mechanism is used to further stabilize the front neck strap, and after the tension adjustment part completes the tension adjustment of the front neck strap, the adjustment component is used to drive the pull rope, and then tighten the two ends of the front neck strap, so that the measuring device can be more stable, and it can prevent the support suction cup from losing suction due to the actions of the patient and the doctor during the measurement process, resulting in poor and inaccurate measurement results of the measuring device.

[0020] 2. The automatic measuring device for carotid stenosis, which is easy to adjust the inner diameter, installs the tensioning adjustment member by installing the fixed installation plate arranged on the outer side of the installation guide plate, twists the adjusting knob, and the adjusting knob drives the adjusting bolt to rotate, and the adjusting bolt drives the U-shaped moving member threadedly connected thereto, so that the U-shaped moving member moves toward the patient's neck, and then the U-shaped moving member pushes the front neck strap when moving. Since the middle part of the front neck strap bypasses the positioning rod, the front neck strap will be pushed to the middle part under the push of the U-shaped moving member. After the detection component on the front neck strap is aligned with the patient's neck pulse and fixed, the front neck strap in front of the patient's neck is adjusted by the tensioning adjustment member, so that the middle part of the front neck strap is closer to the patient's neck part, and then the detection component can be close to the patient's neck pulse; the front neck strap will not be bound at the patient's trachea, resulting in the front neck strap being tightened, causing the patient to have difficulty breathing, physical discomfort and other problems.

[0021] 3. The automatic measuring device for carotid artery stenosis with easy adjustment of inner diameter squeezes the wetting agent toward the inner side of the supporting suction cup through the wetting agent outlet hole provided at the root of the supporting suction cup when the detection component is fixed, so that the supporting suction cup can be better adsorbed on the patient's skin, wherein the air pressure regulating block inside the regulating pipe first moves toward one end of the regulating pipe to discharge the air inside the regulating pipe into the wetting agent outlet hole, and then squeezes the wetting agent inside the wetting agent outlet hole onto the inner side of the supporting suction cup, and at the same time, the other side of the regulating pipe is subjected to negative pressure to extract the air in the supporting airbag, at which time the supporting airbag becomes deflated, and then after the detection component is aligned with the carotid artery, the air pressure regulating block moves toward one end of the regulating pipe to discharge the air inside the regulating pipe into the wetting agent outlet hole, and then squeezes the wetting agent inside the wetting agent outlet hole onto the inner side of the supporting suction cup, and at the same time, the other side of the regulating pipe is subjected to negative pressure to extract the air in the supporting airbag, and at this time, the supporting airbag becomes deflated, and then after the detection component is aligned with the carotid artery, the air pressure regulating block moves toward one end of the regulating pipe to discharge the air inside the regulating pipe into the wetting agent outlet hole, and then squeezes the wetting agent inside the wetting agent outlet hole onto the inner side of the supporting suction cup, and at the same time, the air pressure regulating block moves toward the inner side of the supporting suction cup to discharge the air inside the supporting airbag, and then ... The node moves to the other end of the adjusting pipe, and injects the air at that end of the adjusting pipe into the supporting airbag, so that the deflated supporting airbag swells. At the same time, the other end of the adjusting pipe is subjected to negative pressure, and air is sucked through the wetting agent outlet, so that negative pressure is formed on the inner side of the supporting suction cup, which is adsorbed on the patient's skin to position and preliminarily fix the detection component; so that the detection component can be accurately placed on the patient's carotid artery to avoid the problem that different patients have different body shapes and different neck circumferences. Due to the different neck circumferences of patients, when adjusting the inner diameter of the neck strap, the detection area cannot be aligned with the patient's carotid artery, resulting in poor and inaccurate detection and measurement effects.

[0022] 3. The automatic measuring device for carotid artery stenosis, which is easy to adjust the inner diameter, can operate the support airbags on both sides of the front neck strap independently (the carotid pulse detection component on one side can also be used to detect the patient alone), so as to avoid the situation where there is severe stenosis of the blood vessels on one side of the patient or the width of the blood vessels on both sides is different, and the discomfort to the patient is caused by compressing both carotid arteries at the same time.

[0033] See also Figure 1-Figure 8, an automatic measuring device for carotid stenosis that is convenient for adjusting the inner diameter, comprising a front neckband 1 and a rear fixing frame 2, wherein both sides of the front neckband 1 are connected to the rear fixing frame 2; a throat protection component 3 is arranged on one side of the front neckband 1, and the throat protection component 3 comprises a chin support frame 31 and a positioning rod 32, wherein the chin support frame 31 is arranged on one side of the front neckband 1, and the positioning rod 32 is located in the middle of the chin support frame 31, and one side of the front neckband 1 bypasses the positioning rod 32, and a tensioning adjusting member 33 is arranged on the outer side of the positioning rod 32, and the tensioning adjusting member 33 is used to adjust the tension of the front neckband 1 located on the back of the positioning rod 32; a neck pulse detection component 4 is arranged on the side of the front neckband 1, and the neck pulse detection component 4 is used to fix the neck pulse at the neck The front neck strap 1, the carotid pulse detection component 4 includes a supporting suction cup 41 and a detection component 42, the supporting suction cup 41 is embedded in the front neck strap 1, the supporting suction cup 41 is located on both sides of the detection component 42, a supporting airbag 43 is arranged between the detection component 42 and the front neck strap 1, and an adjustment pipe 44 is arranged at the tail of the supporting airbag 43, and the adjustment pipe 44 is connected with the supporting suction cup 41 and the supporting airbag 43 respectively; a back adjustment mechanism 5 is arranged on the outer side of the middle part of the rear fixing frame 2, the back adjustment mechanism 5 includes an adjustment component 51 and a pull rope 52, one end of the pull rope 52 is connected to the adjustment component 51, and the other end of the pull rope 52 is connected to the front neck strap 1, and the adjustment component 51 is used to adjust the length of the pull rope 52.

[0034] When in use, first pass the patient's head through the measuring device, and put the device on the patient's neck, align it with the patient's throat through the throat protection component 3, and place the chin support frame 31 on the patient's chin, and then place the supporting suction cup 41 in the carotid artery detection component 4 behind the patient's carotid artery; at this time, first, use the adjustment pipe 44 to extract the air in the supporting airbag 43, and align the deflated supporting airbag 43 with the carotid artery. In this process, the adjustment pipe 44 injects air in the direction of the supporting suction cup 41; then use the adjustment pipe 44 again to inflate the supporting airbag 43, and make the supporting airbag 43 bulge, and at the same time, the air at the supporting suction cup 41 is absorbed into the adjusting pipe 44, so that the supporting suction cup 41 close to the patient's neck forms a In a negative pressure state, it can be adsorbed on the patient's neck; further, through the tensioning adjustment member 33, the front neck strap 1 bypassing the positioning rod 32 is tightened inwardly, and in conjunction with the bulging support airbag 43, the detection component 42 on the inner side of the support airbag 43 is directly opposite to and close to the cervical vein; then the front neck strap 1 is further stabilized by the back adjustment mechanism 5. After the tensioning adjustment member 33 completes the tensioning adjustment of the front neck strap 1, the adjustment component 51 is used to drive the pull rope 52, and then tighten the two ends of the front neck strap 1, so that the measuring device can be more stable, and can prevent the support suction cup 41 from losing suction due to the actions of the patient and the doctor during the measurement process, resulting in poor and inaccurate measurement results of the measuring device.

[0035] Specifically, in actual use, the support airbags 43 on both sides of the front neckband 1 can operate independently to avoid the patient's discomfort caused by severe stenosis of one side of the patient's blood vessels or different widths of the blood vessels on both sides, which compresses both carotid arteries at the same time;

[0036] Furthermore, the throat protection component 3 also includes an installation guide plate 34, the installation guide plate 34 is located at both ends of the mandibular support frame 31, and both ends of the positioning rod 32 are respectively installed on the installation guide plate 34, the installation guide plate 34 is slidably connected with the positioning rod 32, and a locking button 35 is provided between the installation guide plate 34 and the positioning rod 32; by setting the installation guide plate 34, the positioning rod 32 is installed between the installation guide plates 34, and when encountering a thin patient, the positioning rod 32 is moved outward from the installation guide plate 34 (to keep the positioning rod 32 away from the patient), and then the locking button 35 is used to fix the positioning rod 32.

[0037] Furthermore, the locking button 35 is slidably arranged at both ends of the positioning rod 32. When the locking button 35 is embedded in the mounting guide plate 34, the locking button 35 and the mounting guide plate 34 are relatively fixed, and support springs 36 are respectively arranged on the opposite sides of the two locking buttons 35, and the support springs 36 are in a compressed and force-accumulated state; the locking button 35 is unlocked by the support springs 36 on the sides of the locking button 35. First, when it is necessary to move the positioning rod 32, the locking button 35 is moved out of the mounting guide plate 34. At this time, the locking button 35 compresses the support spring 36, and then the positioning rod 32 can move between the mounting guide plates 34 to adjust the position of the front neckband 1; when it is necessary to fix the positioning rod 32, the locking button 35 is released, and under the action of the support spring 36, the locking button 35 and the mounting guide plate 34 are squeezed, so that the positioning rod 32 is relatively fixed between the mounting guide plates 34.

[0038] Furthermore, a fixed mounting plate 37 is provided on the outer side of the mounting guide plate 34, and the tension adjusting member 33 is installed on the fixed mounting plate 37. The tension adjusting member 33 includes an adjusting button 331, and an adjusting bolt 332 is provided at one end of the adjusting button 331. The adjusting bolt 332 is rotatably connected to the fixed mounting plate 37. A U-shaped moving member 333 is provided in the middle of the adjusting bolt 332, and the middle of the U-shaped moving member 333 is threadedly connected to the adjusting bolt 332. The tension adjusting member 33 is installed by installing the fixed mounting plate 37 provided on the outer side of the mounting guide plate 34, and the adjusting button 331 is twisted. The movable adjusting bolt 332 rotates, and the adjusting bolt 332 drives the U-shaped moving part 333 threadedly connected thereto, so that the U-shaped moving part 333 moves toward the patient's neck, and then the U-shaped moving part 333 pushes the front neck strap 1 when moving. Since the middle part of the front neck strap 1 bypasses the positioning rod 32, the front neck strap 1 will be close to the middle part under the push of the U-shaped moving part 333. After the detection component 42 on the front neck strap 1 is aligned with the patient's neck pulse and fixed, the front neck strap 1 in front of the patient's neck is adjusted by the tensioning adjusting part 33, so that the middle part of the front neck strap 1 is closer to the patient's neck part, so that the detection component 42 can be close to the patient's neck pulse.

[0039] Furthermore, the two sides of the U-shaped movable member 333 are located on both sides of the fixed mounting plate 37 and extend to the back of the fixed mounting plate 37. The other end of the two sides of the U-shaped movable member 333 is provided with a rolling push rod 334, and the rolling push rod 334 is rotatably connected to the U-shaped movable member 333; by limiting the two sides of the U-shaped movable member 333 under the restriction of the fixed mounting plate 37, the U-shaped movable member 333 can be restricted when moving, and then cooperate with the adjusting bolt 332 to achieve movement. When the U-shaped movable member 333 moves, the rolling push rod 334 at its front end pushes the front neckband 1 to the middle, and when the U-shaped movable member 333 pushes the front neckband 1, the front neckband 1 is damaged.

[0040] Furthermore, a wetting agent outlet hole 45 is provided at the root of the support suction cup 41, one end of the wetting agent outlet hole 45 is located on the inner side of the support suction cup 41, and the other end of the wetting agent outlet hole 45 extends into the regulating pipe 44, and an air pressure regulating block 46 is provided inside the regulating pipe 44; when the air pressure regulating block 46 moves in the regulating pipe 44 toward the tail end of the regulating pipe 44, the support airbag 43 is deflated, and the wetting agent outlet hole 45 is exhausted; when the air pressure regulating block 46 moves in the regulating pipe 44 toward the front end of the regulating pipe 44, the support airbag 43 is inflated, and the wetting agent outlet hole 45 is inhaled; through the wetting agent outlet hole 45 provided at the root of the support suction cup 41, when the detection component 42 is fixed, the wetting agent is squeezed toward the inner side of the support suction cup 41, so that the support suction cup 41 can be better Adsorbed on the patient's skin, wherein the air pressure regulating block 46 inside the regulating pipe 44 first moves to one end of the regulating pipe 44 to discharge the air inside the regulating pipe 44 into the wetting agent outlet 45, and then squeezes the wetting agent inside the wetting agent outlet 45 onto the inner side of the supporting suction cup 41, and at the same time, the other side of the regulating pipe 44 is subjected to negative pressure to extract the air in the supporting airbag 43, at which time the supporting airbag 43 becomes deflated, and then after the detection component 42 is aligned with the carotid pulse, the air pressure regulating block 46 moves to the other end of the regulating pipe 44 to inject the air at this end of the regulating pipe 44 into the supporting airbag 43, so that the deflated supporting airbag 43 swells, and at the same time, the other end of the regulating pipe 44 is subjected to negative pressure, and air is sucked by the wetting agent outlet 45, so that negative pressure is formed on the inner side of the supporting suction cup 41, adsorbed on the patient's skin, and the detection component 42 is positioned and preliminarily fixed;

[0041] The detection component 42 is composed of an existing cervical vein detection chip and the like.

[0042] Furthermore, a linkage block 47 is provided at the tail of the air pressure regulating block 46, and a linkage rod 48 is provided between the linkage block 47 and the air pressure regulating block 46. The linkage block 47 is slidably connected to one end of the linkage rod 48, and the other end of the linkage rod 48 is connected to a driving rod 49, and the driving rod 49 pushes the linkage rod 48 to move; through the linkage block 47 at the tail of the air pressure regulating block 46, when the air pressure regulating block 46 moves, the linkage block 47 is driven to move through the linkage rod 48. Since the linkage block 47 is slidably connected to one end of the linkage rod 48, in the initial stage of the movement of the air pressure regulating block 46, the linkage block 47 will not be in contact with the air pressure regulating block 46. The node block 46 moves together, so that when the support airbag 43 is inflated, the air pressure regulating block 46 moves toward one end of the regulating pipe 44, while the linkage block 47 is stationary at this time, and the air pressure regulating block 46 moves away from the linkage block 47, so that negative pressure is formed between the air pressure regulating block 46 and the linkage block 47. After the air pressure regulating block 46 moves a certain distance, the linkage block 47 is driven to move by the linkage rod 48. At this time, the air pressure regulating block 46 and the linkage block 47 move synchronously, and the distance between the two remains unchanged, that is, the pressure remains unchanged, so that when the air pressure regulating block 46 continues to move, the negative pressure on the inside of the support suction cup 41 will not increase, causing discomfort to the patient.

[0043] Specifically, in actual use, the support airbags 43 on both sides of the front neck strap 1 can be operated independently (the neck pulse detection component 4 on one side can also be used to detect the patient independently), so as to avoid the patient's discomfort caused by the severe stenosis of the blood vessels on one side or the different widths of the blood vessels on both sides, and the compression of the bilateral carotid arteries; the operation can be manually driven by pushing the driving rod 49 to drive the linkage rod 48 to move, thereby realizing the inflation of the support airbag 43, or can be driven by electricity, etc.

[0044] Furthermore, an adjustment mounting frame 21 is provided on the back of the rear fixing frame 2, and an adjustment component 51 is installed on the adjustment mounting frame 21. Stabilizing rods 22 are provided on both sides of the rear fixing frame 2, and the pull rope 52 passes through the stabilizing rod 22; the adjustment component 51 is installed through the adjustment mounting frame 21, and after the support suction cup 41 cooperates with the tensioning adjustment member 33 to fix the detection component 42, the pull rope 52 is driven by the adjustment component 51 to tighten the two sides of the front neckband 1, and at the same time, the pull rope 52 passes through the stabilizing rod 22, so that the pull rope 52 will not fall off the rear fixing frame 2 during use.

[0045] Furthermore, the adjustment assembly 51 includes an adjustment knob 53, a rotating rod 54 is provided on one side of the adjustment knob 53, the pull rope 52 is wound around the rotating rod 54, a check ratchet group 55 is provided between the adjustment knob 53 and the adjustment mounting frame 21, the check ratchet group 55 is coaxially fixed with the adjustment knob 53, after the adjustment knob 53 tightens the pull rope 52, the check ratchet group 55 fixes the adjustment knob 53; by adjusting the adjustment knob 53 in the adjustment assembly 51 3, rotating the adjusting knob 53, driving the rotating rod 54 to rotate, the rotating rod 54 drives the drawstring 52, so that the drawstring 52 is rolled up on the rotating rod 54, and then the connection part between the other end of the drawstring 52 and the front neck strap 1 begins to be tightened, when the adjusting knob 53 is rotated, under the action of the non-return ratchet group 55, the adjusting knob 53 will not rotate in the reverse direction after stopping the rotation; wherein the non-return ratchet group 55 is composed of an existing ratchet and a pawl, and the connection part between the drawstring 52 and the rotating rod 54 is located inside the adjusting mounting frame 21, which is not shown in the figure, such as Figure 7 shown.

[0046] Working principle: When in use, firstly, the patient's head is passed through the measuring device, and the device is put on the patient's neck, the throat protection component 3 is aligned with the patient's throat, and the lower jaw support frame 31 is placed on the patient's lower jaw, and then the support suction cup 41 in the carotid pulse detection component 4 is placed behind the patient's carotid pulse; by setting the installation guide plate 34, the positioning rod 32 is installed between the installation guide plates 34, and before the measuring device is put on the patient's neck, the positioning rod 32 is first moved outward from the installation guide plate 34 (to make the positioning rod 32 away from the patient), and then the locking button 35 is used to fix the positioning rod 32 to facilitate the wearing of the measuring device; wherein the locking button 35 is unlocked by the support spring 36 on the side of the locking button 35, and first when the positioning rod 32 needs to be moved, the locking button 35 is moved out of the installation guide plate 34, at which time the locking button 35 compresses the support spring 36, and then the positioning rod 32 can move between the installation guide plates 34 to adjust the position of the front neckband 1;

[0047] After the measuring device is worn on the patient, the air in the supporting airbag 43 is extracted by the regulating pipe 44, and the deflated supporting airbag 43 is aligned with the neck vein. In this process, the regulating pipe 44 injects air in the direction of the supporting suction cup 41; then the regulating pipe 44 is used to inflate the supporting airbag 43 again, and the supporting airbag 43 is inflated, and at the same time, the air at the supporting suction cup 41 is absorbed into the regulating pipe 44, so that the supporting suction cup 41 closely attached to the patient's neck forms a negative pressure state, and can be adsorbed on the patient's neck;

[0048] In the above process, the wetting agent outlet 45 provided at the root of the supporting suction cup 41 is used to squeeze the wetting agent into the inner side of the supporting suction cup 41 when the detection component 42 is fixed, so that the supporting suction cup 41 can be better adsorbed on the patient's skin, wherein the air pressure regulating block 46 inside the regulating pipe 44 first moves toward one end of the regulating pipe 44, discharges the air inside the regulating pipe 44 into the wetting agent outlet 45, and then squeezes the wetting agent inside the wetting agent outlet 45 into the inner side of the supporting suction cup 41, and at the same time, the air pressure regulating block 46 inside the regulating pipe 44 moves toward one end of the regulating pipe 44, discharges the air inside the regulating pipe 44 into the wetting agent outlet 45, and then squeezes the wetting agent inside the wetting agent outlet 45 onto the inner side of the supporting suction cup 41, and at the same time, the air pressure regulating block 46 inside the regulating pipe 44 moves toward one end of the regulating pipe 44, and ... at the same time, the air pressure regulating block 46 inside the regulating pipe 44 moves toward one end of the regulating pipe 44, and at the same time, the air pressure regulating block 46 inside the regulating pipe 44 moves toward one end of the regulating pipe 44, and at the same time, the air pressure regulating block 46 inside the regulating pipe 44 moves toward one end of the regulating pipe 44, and at the same time, the air pressure regulating block 46 inside the regulating pipe 44 moves toward one end of the regulating pipe 44, and at the same time, the air pressure regulating block 46 inside the regulating pipe 4 Under negative pressure, the air in the supporting airbag 43 is extracted, and the supporting airbag 43 becomes deflated. Then, after the detection component 42 is aligned with the carotid artery, the air pressure regulating block 46 moves to the other end of the regulating pipe 44, and injects the air at this end of the regulating pipe 44 into the supporting airbag 43, so that the deflated supporting airbag 43 swells. At the same time, the other end of the regulating pipe 44 is subjected to negative pressure, and air is sucked through the wetting agent outlet 45, so that negative pressure is formed inside the supporting suction cup 41, which is adsorbed on the patient's skin, so as to position and preliminarily fix the detection component 42.

[0049] The linkage block 47 at the tail of the air pressure regulating block 46 drives the linkage block 47 to move through the linkage rod 48 when the air pressure regulating block 46 moves. Since the linkage block 47 is slidably connected to one end of the linkage rod 48, in the initial stage of the movement of the air pressure regulating block 46, the linkage block 47 will not move with the air pressure regulating block 46, so that when the support airbag 43 is inflated, the air pressure regulating block 46 moves toward one end of the regulating pipe 44, while the linkage block 47 is stationary at this time, and the air pressure regulating block 46 is away from the linkage block 47, so that negative pressure is formed between the air pressure regulating block 46 and the linkage block 47. After the air pressure regulating block 46 moves a certain distance, the linkage block 47 is driven to move by the linkage rod 48. At this time, the air pressure regulating block 46 and the linkage block 47 move synchronously, and the distance between them remains unchanged, that is, the pressure remains unchanged, so that when the air pressure regulating block 46 continues to move, the negative pressure inside the support suction cup 41 will not increase, causing discomfort to the patient;

[0050] The front neck strap 1 bypassing the positioning rod 32 is then tightened inwardly through the tensioning adjusting member 33, and the bulging supporting airbag 43 is cooperated to make the detecting component 42 inside the supporting airbag 43 face and be close to the carotid artery; when it is necessary to fix the positioning rod 32, the locking button 35 is released, and under the action of the supporting spring 36, the locking button 35 and the mounting guide plate 34 are squeezed together, so that the positioning rod 32 is relatively fixed between the mounting guide plates 34; the fixing mounting plate 37 arranged on the outer side of the mounting guide plate 34 is used to install the tensioning adjusting member 33, and the adjusting button 331 is twisted, and the adjusting button 331 drives the adjusting bolt 332 to rotate, and the adjusting bolt 332 drives the U-shaped moving member 333 threadedly connected thereto, so that the U-shaped moving member 333 moves toward the patient's neck, and then the U-shaped moving member 333 pushes the front neck strap 1 to rotate. Belt 1, since the middle part of the front neck strap 1 bypasses the positioning rod 32, the front neck strap 1 will be close to the middle part under the push of the U-shaped moving part 333. After the detection component 42 on the front neck strap 1 is aligned with the patient's neck pulse and fixed, the front neck strap 1 in front of the patient's neck is adjusted by the tensioning adjustment part 33, so that the middle part of the front neck strap 1 is closer to the patient's neck part, so that the detection component 42 can be close to the patient's neck pulse; the two sides of the U-shaped moving part 333 are restricted by the fixed mounting plate 37, so that the U-shaped moving part 333 can be restricted when moving, and then cooperate with the adjusting bolt 332 to achieve movement. When the U-shaped moving part 333 moves, the rolling push rod 334 at its front end pushes the front neck strap 1 to get close to the middle part, and when the U-shaped moving part 333 pushes the front neck strap 1, the front neck strap 1 is damaged;

[0051] Then, the front neckband 1 is further stabilized by the back adjustment mechanism 5. First, the adjustment assembly 51 is installed by using the adjustment mounting frame 21. After the support suction cup 41 cooperates with the tension adjustment member 33 to fix the detection component 42, the adjustment assembly 51 drives the pull rope 52 to tighten the two sides of the front neckband 1. At the same time, the pull rope 52 passes through the stabilizing rod 22 so that the pull rope 52 will not fall off the rear fixing frame 2 during use. The adjustment knob 53 in the adjustment assembly 51 is rotated to drive the rotating rod 54 to rotate, and the rotating rod 54 drives the pull rope 52 so that the pull rope 52 is rolled up. The rotating rod 54 is rotated, and then the other end of the pull rope 52 and the connection part of the front neck strap 1 begin to be tightened. When the adjusting knob 53 is rotated, under the action of the check ratchet group 55, the adjusting knob 53 will not rotate reversely after stopping the rotation; after the tensioning adjusting member 33 completes the tensioning adjustment of the front neck strap 1, the adjusting component 51 is used to drive the pull rope 52, and then tighten the two ends of the front neck strap 1, so that the measuring device can be more stable, and can prevent the supporting suction cup 41 from losing suction due to the actions of the patient and the doctor during the measurement process, resulting in poor and inaccurate measurement effect of the measuring device.
