Description

Technical Field

[0001] This invention relates to the field of vital sign monitoring technology, and in particular to a vital sign monitoring device for use in anesthesiology departments. Background Technology

[0002] Vital signs include four monitoring items: body temperature, pulse, respiration, and blood pressure. Therefore, vital sign monitoring equipment includes thermometers and blood pressure monitors. Sometimes, when patients need to undergo surgery, in order to reduce the patient's pain, medical staff usually anesthetize the patient. After anesthesia and during surgery, it is still necessary to use appropriate equipment to monitor the patient's vital signs in real time.

[0003] When using existing technology to monitor a patient's blood pressure, first place the patient's arm on the bed with the palm facing up, then turn on the blood pressure monitor, wrap the cuff around the middle of the patient's upper arm, place the stethoscope on the patient's brachial artery pulse, slowly inflate the cuff, and slowly deflate it after the pulse disappears. The patient's blood pressure is then monitored by checking the blood pressure monitor to see if it is normal.

[0004] When a patient is awake, their arm muscles may be tense. However, when surgery is required, anesthesia is administered, causing the patient to fall asleep. The anesthesia also relaxes the muscles to some extent, making the patient's arm slightly thinner than when awake. This can cause the cuff wrapped around the patient's arm to become less snug. Furthermore, during surgery, the patient's arm may be moved slightly, and the cuff may slip off due to its looser fit. This instability can affect subsequent blood pressure monitoring. Therefore, we are developing a vital signs monitoring device for anesthesiology departments that can more stably fix the cuff. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies where patient muscle contraction during anesthesia may cause insufficient cuff stability, the technical problem to be solved is to provide a vital signs monitoring device for anesthesiology departments that can more stably fix the cuff.

[0006] The technical solution of the present invention is as follows: a vital signs monitoring device for anesthesiology departments, comprising a blood pressure monitor, a trachea, a hollow ring, a first fixing frame, a first cuff, a second cuff and a first spring, and further comprising a sliding ring and a second spring. The first fixing frame is slidably connected to symmetrically arranged sliding rings, the sliding rings are in contact with the first cuff, the sliding rings are in contact with the second cuff, and at least two second springs are connected between the sliding rings and the first fixing frame.

[0007] In one embodiment, the device further includes a fitting assembly for conforming to and wrapping the patient's arm. The fitting assembly is disposed on the hollow ring and the first cuff. The fitting assembly includes a connecting frame, a fixing ring, an air bladder tube, and an elastic sleeve. The connecting frame is connected to the side of the hollow ring near the first cuff, and the fixing ring is fixed to the side of the first cuff away from the hollow ring. At least two air bladder tubes are connected to the connecting frame. The air bladder tubes are fixed to the fixing ring, and an elastic sleeve is fixed between the connecting frame and the fixing ring. The elastic sleeve is in compression fit with the air bladder tube.

[0008] In one embodiment, an adjustment component for adjusting the extrusion force is further included. The adjustment component is disposed on a first fixed frame and includes a sliding tube, a moving ring, a third spring, an extrusion rod, a fourth spring, an extrusion frame, and a fifth spring. The first fixed frame is slidably connected to symmetrically arranged sliding tubes, which are fixedly connected to adjacent sliding rings. The sliding tubes have at least two slots. A moving ring is fixedly connected to the sliding tube. A third spring connects the moving ring to an adjacent sliding ring. An extrusion rod is slidably connected to the moving ring. The extrusion rod engages with a slot on an adjacent sliding tube and is extruded into the first fixed frame. A fourth spring connects the extrusion rod to an adjacent moving ring. The first fixed frame is slidably connected to symmetrically arranged extrusion frames, which are extruded into the adjacent extrusion rod. A fifth spring connects the first fixed frame to the extrusion frames.

[0009] In one embodiment, a deflation assembly for reducing pressure on the patient's arm is also included. The deflation assembly is disposed on the sliding tube and includes a stop and a sixth spring. The stop is slidably connected to the side of the sliding tube near the adjacent movable ring. The stop engages with the adjacent slot, and the sixth spring connects the stop and the adjacent sliding tube.

[0010] In one embodiment, a wrapping assembly for wrapping a second cuff is also included. The wrapping assembly is disposed on the second cuff and includes a fixing sleeve, a fixing block, and a fixing rod. The fixing sleeve is fitted onto the second cuff, and symmetrically arranged fixing blocks are fixedly connected to the fixing sleeve. At least two fixing rods are fixedly connected at equal intervals to the fixing block on the side closer to the blood pressure monitor, and the fixing rods engage with the fixing block on the side farther from the blood pressure monitor.

[0011] In one embodiment, a locking assembly for locking the fixing sleeve is also included. The locking assembly is disposed on the fixing block and includes a limiting member and a seventh spring. The limiting member is fixedly connected to the fixing rod. The limiting member is in a pressing fit with the adjacent fixing block. At least two seventh springs are connected at equal intervals between the side of the limiting member near the fixing rod and the adjacent fixing rod.

[0012] In one embodiment, a clamping assembly for clamping the patient's arm is also included. The clamping assembly is located on the side of the first fixation frame away from the trachea. The clamping assembly includes a second fixation frame, a screw, an arc-shaped block, and guide rods. The second fixation frame is fixedly connected to the side of the first fixation frame away from the trachea. The second fixation frame is threadedly connected to symmetrically arranged screws. The screws are rotatably connected to the arc-shaped blocks. At least two guide rods are fixedly connected at equal intervals on the side of the arc-shaped blocks near the second fixation frame. The guide rods are slidably connected to the second fixation frame.

[0013] In one embodiment, a support assembly for supporting the fixed sleeve is also included. The support assembly is disposed on the fixed sleeve and includes a third fixed frame, a connecting rod, a support frame, and an eighth spring. At least two third fixed frames are fixedly connected at equal intervals on the side of the fixed sleeve away from the fixed block. A connecting rod is fixedly connected to the side of the third fixed frame close to the second fixed frame. The connecting rod is fixedly connected to the second fixed frame. The support frame is slidably connected to the side of the third fixed frame away from the fixed sleeve. At least two eighth springs are connected at equal intervals between the support frame and the adjacent third fixed frames.

[0014] In one embodiment, a throttle is also included, which is fixedly attached to the screw.

[0015] In one embodiment, an anti-slip pad is also included, with the anti-slip pad fixed to the side of the support frame away from the third fixing frame.

[0016] The beneficial effects of the present invention are as follows: 1. The present invention moves the sliding ring to both sides and squeezes the air between the ring and the first fixing frame, so that the air squeezes the first cuff and the second cuff, thereby allowing the two sides of the first cuff to fit more closely and stably on the patient's arm.

[0017] 2. The present invention expands by inflating the air tube and compressing the elastic sleeve, so that the elastic sleeve can fit and wrap around the patient's arm, thereby indirectly making the first cuff more stably fixed on the patient's arm.

[0018] 3. The present invention adjusts the position of the sliding tube by pressing the inclined surface on the extrusion rod with the extrusion frame, thereby adjusting the air extrusion force on the first cuff, so that the first cuff can better fit and wrap around the patient's arm, and thus the first cuff can be more stably fixed on the patient's arm.

[0019] 4. The present invention indirectly compresses the first cuff by wrapping and squeezing the second cuff with a fixing sleeve, so that the first cuff can fit the patient's arm more closely and thus be more stably fixed on the patient's arm.

[0020] 5. By rotating the screw, the arc-shaped blocks move closer together and clamp the patient's arm, which also helps to make the first cuff more stably fixed on the patient's arm.

[0021] 6. This invention uses a support frame to support the device on the hospital bed or operating table, thereby making the vital signs monitoring equipment used in the anesthesiology department more stable. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Example 1

[0041] A vital signs monitoring device for use in anesthesiology departments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a blood pressure monitor 1, an endotracheal tube 11, a hollow ring 12, a first fixing frame 13, a first cuff 14, a second cuff 15, a first spring 16, a sliding ring 17, and a second spring 18. The endotracheal tube 11 is connected to the lower rear side of the blood pressure monitor 1. The hollow ring 12 is connected to the right side of the endotracheal tube 11. The first cuff 14 is connected to the right side of the hollow ring 12. An air outlet 141 is opened on the lower side of the first cuff 14. The first fixing frame 13 is fixedly connected to the hollow ring 12. The first fixing frame 13 and the first cuff 15 are connected to the first cuff 16. The first fixed frame 13 is fixedly connected to the second cuff 15, and the inner side of the second cuff 15 is connected to the first cuff 14 by a plurality of first springs 16. The inner side of the first fixed frame 13 is slidably connected to two sliding rings 17. The inner side of the sliding rings 17 is in contact with the first cuff 14, and the outer side of the sliding rings 17 is in contact with the second cuff 15. The sides of the sliding rings 17 that are far apart from each other are each wound with a plurality of second springs 18 between them and the first fixed frame 13. The second springs 18 are all wound around the first fixed frame 13.

[0042] When using existing barometers for real-time patient monitoring, if the patient's muscles contract to some extent after anesthesia, the cuff edge in the barometer may no longer fit snugly around the patient's arm, resulting in instability of the cuff and affecting the monitoring of vital signs. Therefore, the anesthesiology department's vital sign monitoring equipment can be used. By using the sliding ring 17 to compress the air between the first cuff 14 and the second cuff 15, the first cuff 14 can fit more snugly around the patient's arm. The specific process is as follows: Medical staff can bring the anesthesiology department's vital sign monitoring equipment to the patient's side, and then pass the patient's arm through the hollow ring 12 and the first cuff 14 in sequence, so that... The first cuff 14 can wrap around the upper middle part of the patient's arm. Medical staff can then activate the blood pressure monitor 1, which delivers air through the trachea 11 to the hollow ring 12, and then through the hollow ring 12 to the first cuff 14. When the air entering the first cuff 14 reaches the air outlet 141, it is expelled through the outlet 141, allowing air to flow between the two sliding rings 17. As more and more air accumulates between the two sliding rings 17, the air compresses them, causing the sliding rings 17 to move away from each other. Correspondingly, the second spring 18 is compressed, and the sliding rings 17 then compress the air between themselves and the first fixing frame 13. Thus, the sliding rings 17 and the first fixing frame 1... 3. The air between the left and right sides will compress the left and right sides of the first cuff 14 and the second cuff 15, causing the first cuff 14 and the second cuff 15 to deform slightly. The first spring 16 will be slightly stretched. In this way, even if the patient's arm muscles contract, the air can compress the first cuff 14, allowing the left and right sides of the first cuff 14 to fit more closely to the patient's arm. This makes the first cuff 14 more stably fixed on the patient's arm and facilitates better real-time monitoring of the patient's blood pressure. When the patient's blood pressure no longer needs to be monitored, medical staff can use the blood pressure monitor 1 and the trachea 11 to evacuate the air from the hollow ring 12 and the first cuff 14. The air between the two sliding rings 17 will... As the pressure gradually decreases, the sliding ring 17 will move and reset to the side closer to each other under the action of the corresponding second spring 18, so that the air no longer compresses the first cuff 14 and the second cuff 15. The first cuff 14 and the second cuff 15 will move and reset appropriately in the opposite direction under the action of the first spring 16. Then, the medical staff can remove the patient's arm. In summary, the air between the sliding ring 17 and the first fixing frame 13 can be compressed to both sides by the sliding ring 17, so that the air between the sliding ring 17 and the first fixing frame 13 gathers to the left and right sides, thereby compressing the first cuff 14 and the second cuff 15, so that the first cuff 14 fits the patient's arm more closely, and thus the first cuff 14 can be more stably fixed on the patient's arm.

[0043] Example 2

[0044] Based on Example 1, such as Figure 5 and Figure 6 As shown, it also includes a fitting component for fitting and wrapping the patient's arm. The fitting component is set on the hollow ring 12 and the first cuff 14. The fitting component includes a connecting frame 2, a fixing ring 21, an airbag tube 22 and an elastic sleeve 23. The connecting frame 2 is connected to the right side of the hollow ring 12. The fixing ring 21 is fixed to the inner right side of the first cuff 14. Multiple airbag tubes 22 are evenly connected to the right side of the connecting frame 2 along the circumferential direction. The right side of each airbag tube 22 is fixed to the fixing ring 21. An elastic sleeve 23 is fixed between the connecting frame 2 and the fixing ring 21. The elastic sleeve 23 and the airbag tube 22 are both squeezed together.

[0045] When monitoring a patient's blood pressure, the patient's arm needs to be passed through the elastic sleeve 23, which wraps around the patient's arm. When air is supplied into the hollow ring 12, it also enters the connecting frame 2, and then the air in the connecting frame 2 flows into the balloon tube 22, causing the balloon tube 22 to gradually inflate and expand. The balloon tube 22 then gradually squeezes the elastic sleeve 23, causing the elastic sleeve 23 to be squeezed closer to the arm, thus making the elastic sleeve 23 fit the patient's arm more closely. This indirectly allows the first cuff 14 to be more stably fixed on the patient's arm, enabling the anesthesiology department to more stably monitor the patient's blood pressure using vital sign monitoring equipment. After the monitoring is completed, the medical staff will withdraw the air through the blood pressure monitor 1, that is, the air in the balloon tube 22 will gradually decrease, and the balloon tube 22 will gradually contract and return to its original position. In this way, the balloon tube 22 will no longer squeeze the elastic sleeve 23, and the elastic sleeve 23 will appropriately contract and return to its original position under its own elasticity.

[0046] like Figure 7 , Figure 8 and Figure 9As shown, it also includes an adjustment assembly for adjusting the extrusion force. The adjustment assembly is mounted on the first fixed frame 13 and includes a sliding tube 3, a moving ring 31, a third spring 32, an extrusion rod 33, a fourth spring 34, an extrusion frame 35, and a fifth spring 36. Multiple sliding tubes 3 are evenly and slidably connected to the left and right sides inside the first fixed frame 13. Each sliding tube 3 is fixedly connected to a nearby sliding ring 17. Each sliding tube 3 has three slots 301. A moving ring 31 is fixedly connected to each sliding tube 3. A third spring 32 is wound between each moving ring 31 and a nearby sliding ring 17. The third spring 32 is wound around the corresponding sliding tube 3. The moving ring 31 has a sliding... A pressing rod 33 is movably connected to the first fixed frame 13. Each pressing rod 33 engages with a slot 301 on a nearby sliding tube 3. Each pressing rod 33 engages with a first fixed frame 13. The front side of each pressing rod 33 is beveled. A fourth spring 34 is wound between each pressing rod 33 and a nearby moving ring 31. Each fourth spring 34 is wound around the corresponding pressing rod 33. Each pressing frame 35 is slidably connected to the left and right sides of the first fixed frame 13. Each pressing frame 35 engages with a beveled surface on a nearby pressing rod 33. Each fifth spring 36 is wound between the left and right sides of the upper part of the first fixed frame 13 and the nearby pressing frame 35. Each fifth spring 36 is wound around the first fixed frame 13.

[0047] like Figure 7 , Figure 8 and Figure 10 As shown, it also includes a deflation assembly for reducing the pressure on the patient's arm. The deflation assembly is set on the sliding tube 3. The deflation assembly includes a stop block 37 and a sixth spring 38. Each of the sliding tubes 3 is slidably connected to a stop block 37. Each stop block 37 is engaged with a corresponding slot 301 of the adjacent sliding tube 3. Each stop block 37 is connected to a sixth spring 38 between it and the adjacent sliding tube 3.

[0048] Initially, the pressing frames 35 are inserted into the first fixed frame 13 on the side closest to each other. When the sliding ring 17 moves to the side furthest from each other, it will drive the corresponding sliding tube 3 to move accordingly. The sliding tube 3 will then drive the corresponding moving ring 31, pressing rod 33, and stop block 37 to move accordingly. The stop block 37 will gradually move out of the first fixed frame 13. When the inclined surface on the pressing rod 33 moves to contact the corresponding pressing frame 35, under the pressure of the pressing frame 35, the pressing rod 33 will move towards the adjacent sliding tube 3, and the fourth spring 34 will be compressed. In this way, the pressing rod 33 will be inserted into the middle slot 301 in the sliding tube 3. At this time, the sliding ring 17 will still move a little to the side furthest from each other, that is, the pressing rod 33 will also move accordingly. When the compression rod 33 can no longer move due to the obstruction of the first fixed frame 13, it is locked into the corresponding slot 301 of the sliding tube 3. Therefore, the sliding tube 3 can no longer move, and the sliding ring 17 can no longer move either. This allows the sliding ring 17 to move a certain distance, increasing the space between the sliding ring 17 and the first fixed frame 13. This reduces the air pressure exerted on the first cuff 14 and the second cuff 15. When the first cuff 14 becomes looser between the medical staff and the patient's arm, requiring increased air pressure between the sliding ring 17 and the first fixed frame 13, the medical staff can move the compression frame 35 to the side furthest from each other. The compression frame 35 moves out slightly, the fifth spring 36 is compressed, and then the medical staff can continue to deliver gas between the two sliding rings 17, causing the sliding rings 17 to continue moving away from each other. When the moving ring 31 and the compression rod 33 move to contact the first fixed frame 13, the moving ring 31 and the compression rod 33 will move towards the adjacent sliding ring 17 under the compression of the first fixed frame 13. The third spring 32 is gradually compressed, and at this time the medical staff can release the compression frame 35. The compression frame 35 will then move back to its original position on the side that is close to each other under the action of the corresponding fifth spring 36. The compression frame 35 will then contact and compress the adjacent compression rod 33. Since the compression rod 33 is no longer aligned with the middle slot 301 on the adjacent sliding tube 3 at this time... Therefore, the compression rod 33 will be compressed and continue to move closer to the adjacent sliding ring 17. The third spring 32 will continue to be compressed. When the compression rod 33 aligns with the innermost slot 301 on the adjacent sliding tube 3, the above steps will be repeated. That is, the compression rod 33 will be inserted into the innermost slot 301 of the adjacent sliding tube 3. At this time, the sliding ring 17 is closer to the left and right sides of the first fixing frame 13, that is, the space between the sliding ring 17 and the first fixing frame 13 is smaller. This allows the air to compress the first cuff 14 and the second cuff 15 with greater force, so that the first cuff 14 is more securely fixed to the patient's arm. Medical staff can also move the stop block 37 closer to the adjacent sliding tube 3.This causes the stop block 37 to be pressed into the adjacent sliding tube 3, compressing the corresponding sixth spring 38. This allows air to flow between the sliding ring 17 and the left and right sides of the first fixing frame 13 into the sliding tube 3 and then out through the corresponding slot 301. This also allows for appropriate adjustment of the compression force on the first cuff 14, ensuring a more snug fit on the patient's arm. After the air is released, the medical staff can release the stop block 37, which will then move back to its original position under the action of the sixth spring 38. The stop block 37 will then block the corresponding slot 301. As the sliding ring 17 moves back to its original position, it will cause the corresponding moving ring 31 and the compression rod 33 to move accordingly. The moving ring 31 will move back to its original position under the action of the third spring 32. As the compression rod 33 gradually moves away from the adjacent compression frame 35, it will move back to its original position away from the adjacent sliding tube 3 under the action of the fourth spring 34.

[0049] like Figure 11 and Figure 12 As shown, it also includes a wrapping assembly for wrapping the second sleeve 15. The wrapping assembly is disposed on the second sleeve 15. The wrapping assembly includes a fixing sleeve 4, a fixing block 41 and a fixing rod 42. The outer ring of the second sleeve 15 is fitted with the fixing sleeve 4. The ends of the fixing sleeve 4 are all fixedly connected to the fixing block 41. Three fixing rods 42 are evenly fixedly connected to the front fixing block 41. The fixing rods 42 are all engaged with the rear fixing block 41.

[0050] like Figure 13 As shown, it also includes a locking assembly for locking the fixing sleeve 4. The locking assembly is set on the fixing block 41. The locking assembly includes a limiting member 43 and a seventh spring 44. The limiting member 43 is fixedly connected to the rear side of the fixing rod 42. The front and rear sides of the limiting member 43 are both inclined. The inclined surfaces on the limiting member 43 are pressed and engaged with the fixing block 41 on the rear side. Multiple seventh springs 44 are evenly wound around the inner side of the limiting member 43 along the circumferential direction and between it and the adjacent fixing rod 42. The seventh springs 44 are all wound around the corresponding limiting member 43.

[0051] After the first cuff 14 and the second cuff 15 are fixed on the patient's arm, the medical staff can also surround the outer ring of the second cuff 15 with the fixing sleeve 4, so that the two fixing blocks 41 are close to each other and the fixing rod 42 can be inserted into the rear fixing block 41. When the inclined surface of the rear side of the limiting member 43 contacts the rear fixing block 41, the medical staff can press the rear fixing block 41 with a little force. The limiting member 43 will contract under the compression of the rear fixing block 41, so that the limiting member 43 can be inserted into the rear fixing block 41. The corresponding seventh spring 44 is compressed until the limiting member 43 and the fixing rod 42 can be inserted out of the rear fixing block 41. The limiting member 43 will extend and return to its original position under the action of the corresponding seventh spring 44. In this way, the two fixing blocks 41 can be locked by the limiting member 43, thereby allowing the fixing sleeve to be secured. 4. Wrap and squeeze the second cuff 15, thereby squeezing the air between the second cuff 15 and the first cuff 14, causing the air to compress the first cuff 14, thus making the first cuff 14 fit the patient's arm more closely, and thus making the first cuff 14 more stably fixed on the patient's arm. When blood pressure monitoring is no longer required, the rear compression fixing block 41 can be moved backward with a little force. The rear fixing block 41 will then squeeze the front of the limiting member 43, and the above steps will be repeated, that is, the limiting member 43 will be squeezed and contracted, and the corresponding seventh spring 44 will be compressed, until the two fixing blocks 41 separate, that is, the fixing rod 42 and the limiting member 43 move out of the rear fixing block 41. The limiting member 43 will then extend and return to its original position under the action of the corresponding seventh spring 44. At this time, the medical staff can remove the fixing sleeve 4.

[0052] like Figure 14 As shown, it also includes a clamping assembly for clamping onto the patient's arm. The clamping assembly is located on the right side of the first fixing frame 13. The clamping assembly includes a second fixing frame 5, a screw 51, an arc block 52, and guide rods 53. The second fixing frame 5 is fixedly connected to the right side of the first fixing frame 13. The screw 51 is threadedly connected to both the front and rear sides of the second fixing frame 5. The arc block 52 is rotatably connected to the side of the screw 51 that is close to each other. Four guide rods 53 are evenly fixed to the outer side of the arc block 52. The guide rods 53 are all slidably connected to the second fixing frame 5.

[0053] like Figure 14 As shown, it also includes a throttle 511, and the throttle 511 is fixed to the side of the screws 51 that are far apart from each other.

[0054] When the patient's arm passes through the first cuff 14, it also passes between the two arc-shaped blocks 52. Then, medical staff can rotate the screw 51 appropriately through the handle 511, causing the screw 51 to move towards the side closer to each other, which in turn moves the corresponding arc-shaped blocks 52 and guide rods 53 until the arc-shaped blocks 52 can fit and clamp the patient's arm. This further ensures that the vital signs monitoring equipment used in this anesthesia department is more stably fixed on the patient's arm, which also helps to make the first cuff 14 more stably fixed on the patient's arm. After the monitoring is completed, medical staff can rotate the screw 51 in the opposite direction through the handle 511, causing the screw 51 to move and reset towards the side further away from each other, which in turn moves and resets the corresponding arc-shaped blocks 52 and guide rods 53.

[0055] like Figure 15 and Figure 16 As shown, it also includes a support assembly for supporting the fixed sleeve 4. The support assembly is disposed on the fixed sleeve 4 and includes a third fixed frame 6, a connecting rod 61, a support frame 62 and an eighth spring 63. Three third fixed frames 6 are evenly fixed to the lower side of the fixed sleeve 4. A connecting rod 61 is fixed to each of the third fixed frames 6. The right side of each connecting rod 61 is fixed to a second fixed frame 5. The support frame 62 is slidably connected to the lower side of each third fixed frame 6. Multiple eighth springs 63 are evenly connected between the inner upper side of the support frame 62 and the adjacent third fixed frame 6.

[0056] like Figure 15 and Figure 16 As shown, it also includes an anti-slip pad 631, and the lower side of the support frame 62 is fixed with an anti-slip pad 631.

[0057] When the vital signs monitoring device is fixed to the patient's arm, it can be supported on the bed and operating table by the support frame 62 and the anti-slip pad 631. The patient's arm will press down on the third fixation frame 6, causing the eighth spring 63 to contract. In this way, the patient's arm can be placed more stably by the third fixation frame 6 and the support frame 62, which helps to prevent the vital signs monitoring device from shaking due to large rotation of the patient's arm. The anti-slip pad 631 can also increase the friction between the support frame 62 and the bed and operating table, which helps to make the vital signs monitoring device more stable. When the patient's arm is removed, that is, when the patient's arm no longer presses down on the third fixation frame 6, the third fixation frame 6 will move upward and reset under the action of the eighth spring 63.
