Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a medical baby stroller with a joint folding and locking structure. Background Technology

[0002] A baby stroller is a "vehicle" designed specifically for babies, and it requires someone to push or pull it to move.

[0003] In the present technology, the rear of the stroller is generally designed to be height-adjustable to accommodate people of different heights. To facilitate user adjustment, the adjustment device is usually designed on the handle at the rear of the stroller. On the other hand, to facilitate the storage of the stroller, existing strollers are also designed to be foldable, and the switch for starting the folding is usually also located on the handle at the rear of the stroller. Therefore, when the user adjusts the height of the rear of the stroller, it is easy to accidentally touch the folding switch, which may cause the infant inside the stroller to be pinched and injured. Summary of the Invention

[0004] The purpose of this application is to provide a medical baby stroller with a joint folding and locking structure, which can minimize the possibility of users accidentally activating the folding switch when adjusting the height of the stroller's rear, thereby reducing the risk of injury to infants and young children.

[0005] The medical baby stroller with a joint folding and locking structure provided in this application adopts the following technical solution: a stroller body, the rear of which is connected to a stroller handle;

[0006] The connecting assembly includes a snap ring, a first snap sleeve, and a second snap sleeve. The first snap sleeve is connected to the vehicle body, and the second snap sleeve is connected to the trolley handle. The first and second snap sleeves are rotatably connected. Each of the opposite end faces of the first and second snap sleeves has a snap groove. The snap ring is coaxially located in the snap grooves on both the first and second snap sleeves, and both the first and second snap sleeves are slidably snapped into the snap ring.

[0007] An adjusting member is installed on the trolley handle. The adjusting member is used to drive the snap ring to move in a direction away from the second snap sleeve. The snap ring is also provided with a limiting member. The limiting member is used to divide the adjustment range of the adjusting member into a first position and a second position. When the limiting member is activated, the limiting member can keep the adjusting member in the first position.

[0008] The linkage mechanism is provided in the vehicle body, which includes a first frame, a second frame, and a third frame. Each of the second frame, the third frame, and the first frame is provided with a connecting component and an adjusting component. When the limiting component is closed, the adjusting component on the trolley handle can reach the second position, thereby activating the adjusting component between the second frame, the third frame, and the first frame through the linkage mechanism, thus facilitating the rotation and folding of the second frame, the third frame, and the first frame.

[0009] Optionally, the adjusting component includes a fixed base, a slider, a traction rope, a compression ring, and a guide block. The fixed base is mounted on the trolley handle and has a groove for the slider to slide into. The compression ring is located inside the second snap-fit ​​sleeve. One end of the compression ring abuts against the wall of the snap-fit ​​groove on the second snap-fit ​​sleeve, and the other end of the compression ring abuts against the snap-fit ​​ring. A guide block is provided in the wall of the snap-fit ​​groove on the second snap-fit ​​sleeve. The compression ring has a guide groove for the compression block to be inserted into. The compression ring is connected to the traction rope on its ring wall, and the other end of the traction rope is connected to the fixed base. When the slider slides in the direction close to the fixed base, it will drive the traction rope to move in the direction away from the compression ring. The traction rope is an elastic rope.

[0010] Optionally, the limiting component includes a limiting seat, a limiting top, a limiting post, and a reset block. The limiting seat is mounted on the second snap-fit ​​sleeve, and the limiting top is slidably mounted on the limiting seat. The second snap-fit ​​sleeve has a first sliding groove for the limiting top to be inserted into. The end of the limiting top near the first sliding groove is set as an inclined side, and the inclined side of the limiting top slides against the groove wall of the first sliding groove.

[0011] The second snap-fit ​​sleeve is also provided with a second sliding groove for the limiting post to slide into. The second sliding groove is arc-shaped. The end of the limiting post away from the limiting seat is connected to a first spring. The end of the first spring away from the limiting post is connected to the first snap-fit ​​sleeve. The second snap-fit ​​sleeve is also provided with a top cover that slides on it. The top cover abuts against the end of the limiting post away from the first spring, and the top cover can be inserted into the second sliding groove. The limiting seat is provided with a reset groove for the reset block to slide into. A second spring is provided between the reset block and the groove wall of the reset groove. The reset block slides against the top cover and the limiting top member simultaneously. When the top cover moves in the direction closer to the limiting post, the limiting post is pushed towards the first snap-fit ​​sleeve.

[0012] Optionally, the linkage includes a winding reel, a first sliding member, and a second sliding member. The winding reel is connected to the second snap-fit ​​sleeve. The first sliding member is slidably mounted on the second frame, and the second sliding member is slidably mounted on the third frame. The winding reel and the first sliding member are connected by a traction rope. A connecting rod is provided between the first sliding member and the second sliding member. The second sliding member is connected to the compression block in the adjusting member inside the first frame.

[0013] Optionally, the vehicle body is equipped with an IV stand, which has a holder for placing medicine bottles. The lower end of the medicine bottle is connected to an IV tube, and the IV tube has a buffer chamber. The IV stand is equipped with an adjustment component for adjusting the height of the IV stand. A detection component for detecting the human heart rate is also used in conjunction with the IV stand. The IV stand has a control center, and the adjustment component and the detection component are electrically connected to the control center. The height of the control center is the same as the height of the buffer chamber on the IV tube. The IV stand is also equipped with a monitoring component that can monitor whether there is still medicine in the medicine bottle.

[0014] Optionally, the adjustment component includes a pressure sensor, the output of which is coated with adhesive for mounting at the location of the human heart. The pressure sensor converts pressure signals into electrical signals and transmits them to the control center via sound waves.

[0015] Optionally, the adjustment assembly includes an electrically telescopic rod mounted on the vehicle body, and the IV stand is mounted on the output end of the electrically telescopic rod.

[0016] Optionally, the electric telescopic rod is equipped with a storage device for storing excess infusion tubing.

[0017] Optionally, the storage component includes a placement container, in which a limiting post is coaxially disposed. A gap is left between the outer peripheral wall of the limiting post and the inner peripheral wall of the placement container. The width of the gap is the same as the diameter of the infusion tube. The infusion tube is located in the gap and is spirally wound around the outer peripheral wall of the limiting post.

[0018] Optionally, a heating element is provided inside the limiting post.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The limiting component in this application can limit the adjustment range of the adjusting component on the stroller handle to the first position. Therefore, no matter how the adjusting component on the stroller handle is adjusted, it can only adjust the height of the stroller handle. When the stroller needs to be folded, the limiting component only needs to be closed, and the adjustment range of the adjusting component on the stroller handle can reach the second position. When the adjustment range of the adjusting component on the stroller handle reaches the second position, the adjusting component installed on the stroller handle can activate the adjusting component between the second frame, the third frame and the first frame through the linkage component, thereby realizing the folding of the stroller body. This structure mainly prevents the adjusting component between the second frame, the third frame and the first frame from being easily activated through the setting of the limiting component. Therefore, when the limiting component is always in the activated state, the stroller body cannot be folded, thereby minimizing the possibility of the folding switch on the stroller body being accidentally touched, which could lead to the infant being pinched and injured inside the stroller, thus improving the protection effect for the infant.

[0021] 2. Since the infusion rate is related to the height between the buffer chamber and the human heart, the infusion rate can be adjusted by adjusting the height of the buffer chamber on the infusion stand and tubing. When the buffer chamber on the infusion tubing is level with the height of the human heart, the infusion rate is the lowest. As the position of the buffer chamber on the infusion stand and tubing rises, the infusion rate gradually increases. However, the infusion rate cannot be too fast, otherwise the human body cannot withstand it. Therefore, the pressure sensor detects the frequency of the human heartbeat to display the load on the human heart. The gradual rise of the infusion stand indicates that the infusion rate is faster, the load on the human heart is greater, and the heartbeat frequency is also faster. Therefore, the height of the buffer chamber on the infusion stand and tubing can be controlled at a specified height by using the value of the pressure sensor to ensure that the infusion rate is most suitable for the human body.

[0022] 3. The pressure sensor transmits signals to the control center in the form of sound waves. Since the height of the control center is the same as the height of the buffer chamber, based on the principle of the shortest diameter distance, when the pressure sensor at the heart can transmit the signal to the control center in the shortest time, it indicates that the heart and the buffer chamber of the infusion tube are at the same height, meaning the infusion rate is at its slowest. This method allows for the rapid determination of the initial position of the infusion stand and the buffer chamber on the infusion tube, enabling the infusion rate to gradually increase at the slowest speed. This allows the body to slowly adapt to the infusion process, reducing discomfort. Furthermore, when the monitoring component detects that the medication has drained, the adjustment component immediately adjusts the buffer chamber on the infusion tube to be level with the heart. Since there is no new medication in the buffer chamber, according to the principle of communicating vessels, the medication in the buffer chamber will not enter the bloodstream through the infusion tube. This minimizes the risk of air entering the bloodstream or blood backflow due to staff error such as failure to remove the needle in time, thus significantly improving the safety of the equipment and reducing the likelihood of medical accidents.

[0023] 4. The placement tank and limiting post design allow excess length of the infusion tubing to be stored, thus minimizing the risk of the tubing being pulled by external forces. Furthermore, since the distance between the inner wall of the placement tank and the outer wall of the limiting post is equal to the diameter of the infusion tubing, the tubing will not become tangled or knotted when it is being wound and stored, further reducing the probability of medical accidents.

Detailed Implementation

[0044] The following combination Figure 1-19 This application will be described in further detail below.

[0045] A medical baby stroller with a joint folding and locking structure, as shown in the reference. Figures 1-9 It includes the vehicle body 1, connecting components 2, adjusting components 3, and linkage components 5.

[0046] The rear of the vehicle body 1 is connected to a trolley handle 11, which is rotatably connected to the vehicle body 1 via a connecting assembly 2.

[0047] In this embodiment, the connecting component 2 is provided in two sets. The trolley handle 11 and the trolley body 1 have two connection points. The two sets of connecting components 2 correspond one-to-one with the two connection points. The connecting component 2 includes a snap ring 23, a first snap sleeve 21 and a second snap sleeve 22.

[0048] The first snap-fit ​​sleeve 21 is fixedly connected to the vehicle body 1, and the second snap-fit ​​sleeve 22 is fixedly connected to the trolley handle 11. The first snap-fit ​​sleeve 21 and the second snap-fit ​​sleeve 22 are coaxially arranged and rotatably connected. The opposite end faces of the first snap-fit ​​sleeve 21 and the second snap-fit ​​sleeve 22 are coaxially provided with snap-fit ​​grooves 211. The groove walls of the snap-fit ​​grooves 211 on the first snap-fit ​​sleeve 21 and the second snap-fit ​​sleeve 22 are provided with internal teeth. Multiple internal teeth are evenly spaced around the axis of the first snap-fit ​​sleeve 21 and the second snap-fit ​​sleeve 22. The snap-fit ​​ring 23 is coaxially located in the snap-fit ​​grooves 211 of the first snap-fit ​​sleeve 21 and the second snap-fit ​​sleeve 22. Multiple external teeth are evenly spaced on the outer peripheral wall of the snap-fit ​​ring 23. The internal teeth on the groove walls of the snap-fit ​​grooves 211 in the first snap-fit ​​sleeve 21 and the second snap-fit ​​sleeve 22 mesh with the external teeth on the snap-fit ​​ring 23. The first snap-fit ​​sleeve 21 and the second snap-fit ​​sleeve 22 can slide relative to the snap-fit ​​ring 23 in the coaxial direction.

[0049] The adjusting component 3 includes a fixed base 31, a slider 32, a traction rope 33, a compression ring 34, and a guide block 35.

[0050] The fixing seat 31 is fixedly installed on the trolley handle 11. The fixing seat 31 has a sliding groove 311 for the slider 32 to slide into. The fixing seat 31 has two limiting grooves 312, which correspond one-to-one with the two connecting components 2. The entire interior of the vehicle body 1 and the trolley handle 11 is hollow. In this embodiment, the traction rope 33 is located inside the trolley handle 11. Similarly, in this embodiment, there are two traction ropes 33, which correspond one-to-one with the two limiting grooves 312. In this embodiment, one end of the traction rope 33 is set as... The T-shaped end of the traction rope 33 is engaged in the limiting groove 312 of the fixed base 31. The groove wall of the limiting groove 312 is also provided with a through hole 313 for the traction rope 33 to pass through. The T-shaped end of the traction rope 33 can slide in the limiting groove 312. The other end of the traction rope 33 passes through the through hole 313 and is fixedly connected to the peripheral wall of the compression ring 34. The compression ring 34 is coaxially located in the second snap-fit ​​sleeve 22. One end of the compression ring 34 abuts against the groove wall of the snap-fit ​​groove 211 on the second snap-fit ​​sleeve 22. It should be noted that the traction rope 33 in this embodiment is set as an elastic rope.

[0051] The slider 32 is also provided with a through groove 321 for the T-shaped end of the traction rope 33 to pass through. The opening direction of the through hole 313 on the fixed base 31 is perpendicular to the opening direction of the through groove 321 on the slider 32. The groove wall of the through groove 321 on the slider 32 is set as a relatively inclined surface, and the groove wall slides against the T-shaped end of the traction rope 33.

[0052] The other end of the compression ring 34 abuts against the snap ring 23. Multiple guide blocks 35 are fixedly installed in the groove wall of the snap groove 211 on the second snap sleeve 22. In this embodiment, three guide blocks 35 are provided, evenly spaced around the axis of the second snap sleeve 22. Each of the three guide blocks 35 in this embodiment has a frustum shape, and one side of each guide block 35 has a bevel. The compression ring 34 has three guide grooves 341 that match the shape of the guide blocks 35. Each guide groove 341 corresponds to one guide block 35, and the guide blocks 35 slide into the guide grooves 341 (in conjunction with...). Figure 10 and Figure 11 ).

[0053] Reference Figure 5 , Figure 6 and Figure 8 In this embodiment, the limiting component 4 includes a limiting seat 41, a limiting top component 42, a limiting post 43, and a reset block 44.

[0054] The limiting seat 41 is fixedly installed on the second retaining sleeve 22, and the limiting top member 42 is slidably installed on the limiting seat 41. The first retaining sleeve 21 has a first sliding groove 221 for the limiting top member 42 to be inserted. The end of the limiting top member 42 away from the limiting seat 41 is pointed, and the bevel of the tip of the limiting top member 42 slides against the groove wall of the first sliding groove 221. The second retaining sleeve 22 is also provided with a second sliding groove 222 for the limiting post 43 to be slidably inserted. The second sliding groove 222 is arc-shaped. The end of the limiting post 43 away from the limiting seat 41 is fixedly connected to a first spring 45. The end of the first spring 45 away from the limiting post 43 is connected to the first retaining sleeve 22. 1. Fixed connection, the second snap sleeve 22 is also slidably provided with a top cover 212, the top cover 212 abuts against the end of the limiting post 43 away from the first spring 45, and the top cover 212 can push the limiting post 43 out of the second sliding groove 222. The limiting seat 41 is provided with a reset groove 411 for the reset block 44 to slide into. The reset block 44 and the groove wall of the reset groove 411 are provided with a second spring 46. The reset block 44 slides against the top cover 212 and the limiting member 4 at the same time. The top cover 212 is also provided with a groove 2121. When the top cover 212 moves in the direction close to the limiting post 43, the limiting post 43 is pushed in the direction close to the first snap sleeve 21.

[0055] Reference Figure 1 The vehicle body 1 includes a first frame 12, a second frame 13 and a third frame 14.

[0056] The second frame 13, the third frame 14 and the first frame 12 are each provided with a connecting component 2 and an adjusting component 3. When the limiting component 4 is closed, the adjusting component 3 on the trolley handle 11 can reach the second position, thereby activating the adjusting component 3 between the second frame 13, the third frame 14 and the first frame 12 through the linkage component 5, so as to facilitate the rotation and folding of the second frame 13, the third frame 14 and the first frame 12.

[0057] Reference Figure 1 , Figure 13 , Figure 14 and Figure 15 The linkage 5 includes a winding disc 51, a first sliding member 52, and a second sliding member 53.

[0058] The winding reel 51 is connected to the second snap-fit ​​sleeve 22. The first sliding member 52 is slidably mounted on the second frame 13, and the second sliding member 53 is slidably mounted on the third frame 14. The winding reel 51 and the first sliding member 52 are connected by a traction rope 33. A connecting rod 54 is provided between the first sliding member 52 and the second sliding member 53. The second sliding member 53 is connected to the pressing block in the adjusting member 3 inside the first frame 12. The first sliding member 52 includes a housing 521 and a first sliding block 522. The second sliding member 53 includes a housing 521 and a second sliding block 531. The housing 521 of the first sliding member 52 is slidably sleeved on the second frame 13. The first sliding block 522 is located inside the second frame 13. The outer shell 521 of the second sliding member 53 is slidably sleeved on the third frame 14. The second sliding block 531 is located inside the third frame 14. The opposite end faces of the second frame 13 and the third frame 14 are provided with linkage grooves 131 for the connecting rod 54 to pass through and slide. The outer shell 521 and the first sliding block 522 of the first sliding member 52 are provided with first connecting grooves 5221 for one end of the connecting rod 54 to be inserted. The outer shell 521 and the second sliding block 531 of the second sliding member 53 are provided with second connecting grooves 5311 for the other end of the connecting rod 54 to be inserted.

[0059] When the stroller is in its normal state, the top cover 212 and the reset block 44 are always in contact. Therefore, the top cover 212 always applies pressure to the reset block 44 in the direction close to the reset groove 411. The reset block 44 will slide in the direction close to the inside of the reset groove 411. The reset block 44 located in the reset groove 411 will always be under pressure. At this time, the reset block 44 will not squeeze the limiting top member 42. In addition, the limiting post 92 is always in the second slide groove 222. Since the limiting post 92 is fixedly connected to the first locking sleeve 21 by the first spring 45, the first locking sleeve 21 and the second locking sleeve 22 can only slide a distance of the length of the second slide groove 222 due to the restriction of the limiting post 43.

[0060] As can be seen from the above, when the height of the handlebar needs to be increased, simply lift the handlebar 11, and the handlebar 11 will cause the second locking sleeve 22 and the first locking sleeve 21 to rotate coaxially relative to each other. When the height of the handlebar needs to be decreased, simply press down the handlebar 11. At the same time, due to the effect of the limiting post 43, the relative rotation displacement of the first locking sleeve 21 and the second locking sleeve 22 is the length of the arc of the second slide groove 222. Therefore, no matter how the handlebar 11 is lifted or pressed down, it will not be able to completely fit against the vehicle body 1, that is, the vehicle body 1 cannot be folded. This minimizes the risk of the folding switch on the vehicle body 1 being accidentally activated, which could lead to the infant being pinched inside the vehicle.

[0061] When the vehicle body 1 needs to be folded, simply press the top cover 212 towards the direction of the limiting post 43. The top cover 212 will then push the limiting post 43 towards the direction of the first snap-fit ​​sleeve 21 until the limiting post 43 is pushed out of the first slide groove 221. At this time, the top cover 212 will no longer press the reset block 44, and the reset spring will begin to reset and extend, thereby driving the reset block 44 to move away from the reset spring until one end of the reset block 44 is inserted into the groove 2121 on the top cover 212. At the same time, the reset block 44... The positioning block 44 also presses against the limiting top member 42, thereby causing the limiting top member 42 to slide into the second slide groove 222 until the beveled edge of the limiting top member tip abuts against the gear on the locking ring 23. At the same time, one end of the reset block 44 abuts against the groove wall of the groove 2121. Therefore, the reset block 44 prevents the top cover 212 from moving back, so that the top cover 212 is always in the state of pressing against the limiting post 43, thereby keeping the first spring 45 in a compressed state. That is, the limiting post 43 is always outside the first slide groove 221. Then, by pressing... The slider 32 on the trolley handle 11 slides into the groove 311. During its movement, the groove wall 321 on the slider 32 presses against the T-shaped end of the traction rope 33, causing the traction rope 33 to move away from the winding reel 51. This, in turn, causes the winding reel 51 to rotate on its own axis. Since the winding reel 51 is coaxially and fixedly connected to the compression ring 34, the compression ring 34 rotates. Due to the guide block 35, the compression ring 34 rotates while the compression ring 34 is being compressed. Ring 34 also moves in the direction close to the snap ring 23 until the squeezing ring 34 pushes the snap ring 23 to separate from the second snap sleeve 22, that is, the gear on the snap ring 23 separates from the tooth groove on the second snap sleeve 22. Therefore, when the trolley handle 11 is pressed down, since there is no restriction of the limiting post 43, the second snap sleeve 22 on the trolley handle 11 and the first snap sleeve 21 on the trolley body 1 can rotate without restriction until the trolley handle 11 and the trolley body 1 are in contact, thus realizing the folding of the trolley handle 11 and the trolley body 1.

[0062] Additionally, a traction rope 33 is also provided on the compression ring 34, which is coaxially fixedly connected to the winding reel 51. The other end of the traction rope 33 on the compression ring 34 is connected to the first sliding member 52. When the compression ring 34 rotates, the traction rope 33 on the compression ring 34 drives the first sliding member 52 to move upward. Then, the first sliding member 52 drives the second sliding block 32 to move upward through the connecting rod 54. The first sliding member 52 is connected to the compression ring 34 in the adjusting member 3 on the second frame 13 through the traction rope 33. Connected to the compression ring 34 in the adjustment on the third frame 14, the traction rope 33 will drive the compression ring 34 in the adjustment member 3 on the second frame 13 and the third frame 14 to rotate during the upward movement of the first sliding member 52 and the second sliding member 53. Then, following the principle of the above process, the first frame 12 can rotate with the second frame 13 and the third frame 14, which means that the second frame 13, the third frame 14 and the first frame 12 can be folded, thus completing the folding function of the whole vehicle.

[0063] It should be noted that in the limiting member 4 between the trolley handle 11 and the trolley body 1, when the first locking sleeve 21 and the second locking sleeve 22 rotate relative to each other, the second locking sleeve 22 will drive the limiting top member 42 to rotate. At this time, the toothed groove on the locking ring 23 will press the inclined side of the limiting top member 42, thereby driving the limiting top member 42 to move in the direction close to the reset groove 411, that is, the retraction of the limiting top member 42. During the retraction of the limiting top member 42, the limiting top member 42 will press the reset block 44, so that the reset block 44 is reset. The position block 44 moves upward, the reset spring is compressed again, and the reset block 44 will slide out from the groove 2121 on the top cover 212. That is, the reset block 44 will not restrict the top cover 212. Therefore, the top cover 212 will also move back under the reset of the first spring 45 and the limiting post 43, thereby re-pressing the reset block 44. That is, the reset block 44, the reset spring, the limiting top member 42, the limiting post 43, the first spring 45 and the top cover 212 are all restored to their initial state for the next use.

[0064] Reference Figure 16 , Figure 17 and Figure 18 In this embodiment, the vehicle body 1 is also equipped with an infusion stand 6. The top of the infusion stand 6 is fixedly equipped with a holder 61 for placing medicine bottles 7. The lower end of the medicine bottles 7 is connected to an infusion tube 8. The infusion tube 8 is equipped with a buffer chamber 81. The infusion stand 6 is equipped with an adjustment component 63 for adjusting the height of the infusion stand 6. In this embodiment, the adjustment component 63 is set as an electric telescopic rod. The electric telescopic rod is fixedly installed on the vehicle body 1, and the infusion stand 6 is fixedly installed on the output end of the electric telescopic rod.

[0065] In this embodiment, a detection component 64 for detecting the heart rate is used in conjunction with the infusion stand 6. In this embodiment, the detection component 64 is a pressure sensor. The output end of the pressure sensor is coated with glue so that the pressure sensor can be installed at the location of the human heart. The pressure sensor can convert the pressure signal into an electrical signal and transmit it to the control center 651 through sound waves. The height of the control center 651 is the same as the height of the buffer cavity 81 on the infusion tube 8. The pressure sensor and the electric telescopic rod are electrically connected to the control center 651. The infusion stand 6 is also equipped with a monitoring component 66 that can monitor whether there is still medicine in the medicine bottle 7. In this embodiment, the monitoring component 66 includes a laser emitter 661 and a laser receiver 662. A bracket 65 is fixedly connected to the infusion stand 6. The bracket 65 has a relief groove 652 for placing the buffer cavity 81. The laser emitter 661 and the laser receiver 662 are both mounted on the bracket 65 and are arranged opposite each other on both sides of the upper part of the buffer cavity 81.

[0066] When intravenous infusion is required, the pressure sensor is first attached to the patient's heart. Then, the height of the buffer chamber 81 on the infusion stand 6 is adjusted to match the height of the patient's heart. Since the pressure sensor transmits signals to the control center 651 in the form of sound waves, and since the height of the control center 651 is the same as the height of the buffer chamber 81, based on the principle of the shortest diameter distance, it can be known that when the pressure sensor at the patient's heart can transmit signals to the control center 651 in the shortest time, it indicates that the patient's heart and the buffer chamber 81 of the infusion tube 8 are at the same height, which is the slowest infusion rate. In this way, the initial positions of the infusion stand 6 and the buffer chamber 81 on the infusion tube 8 can be quickly determined, so that the infusion rate can gradually increase at the slowest speed, allowing the patient to slowly adapt to the infusion process and reducing the discomfort caused by the infusion.

[0067] It should be noted that during intravenous infusion, the heart, blood vessels, infusion tube 8, and buffer chamber 81 form a communicating vessel. Therefore, when the height of buffer chamber 81 is the same as that of the heart, the medication in infusion tube 8 and the blood in the blood vessels are in a relatively balanced state. Since the medication in the medicine bottle 7 continuously enters the buffer chamber 81, the medication in the buffer chamber 81 will continuously enter the blood vessels through the infusion tube 8. Therefore, according to the principle of communicating vessels, the higher the height of buffer chamber 81, the faster the medication in infusion tube 8 flows into the blood vessels, that is, the faster the infusion rate.

[0068] In addition, in this embodiment, the laser emitter 661 passes through the buffer chamber 81, and medication is continuously dripped into the buffer chamber 81. Therefore, the laser emitted by the laser emitter 661 is blocked by the droplets in the buffer chamber 81, meaning that the received signal of the laser receiver 662 will regularly increase and decrease. Therefore, when the signal received by the laser receiver 662 is consistently at a high peak, it indicates that no more medication is entering the buffer chamber 81, meaning that the medication in the medicine bottle 7 has been drained. At this time, the control center 651 will immediately control the electric telescopic rod to adjust the buffer chamber 81 on the infusion tube 8 to be level with the human heart. Since there is no new medication in the buffer chamber 81, according to the principle of communicating vessels, the medication in the buffer chamber 81 will no longer enter the human blood vessels through the infusion tube 8. This minimizes the possibility of air flowing into the human blood vessels or blood backflow due to staff error in not removing the needle in time, thus minimizing the occurrence of medical accidents and greatly improving the safety of this device.

[0069] Finally, refer to Figure 17 and Figure 19 In this embodiment, a storage component 9 for storing excess infusion tubes 8 is provided on the side wall of the electric telescopic rod. The storage component 9 in this embodiment includes a placement tank 91.

[0070] A limiting post 92 is coaxially installed inside the placement tank 91. A through hole 313 for the infusion tube 8 to pass through is opened on the peripheral wall of the placement tank 91. A gap is left between the outer peripheral wall of the limiting post 92 and the inner peripheral wall of the placement tank 91. The width of this gap is the same as the diameter of the infusion tube 8. The infusion tube 8 is located in this gap and is spirally wound around the outer peripheral wall of the limiting post 92. Therefore, when the electric telescopic rod extends, the infusion tube 8 inside the placement tank 91 will be spirally pulled out. Since part of the infusion tube 8 is already spirally wound inside the placement tank 91, when the electric telescopic rod retracts... The excess infusion tube 8 will also spiral into the gap between the outer peripheral wall of the limiting post 92 and the inner peripheral wall of the placement tank 91 due to inertia, thereby minimizing the possibility of the infusion tube 8 becoming tangled or knotted when it is being stored, thus further reducing the probability of medical accidents. In addition, in this embodiment, a heating element 93 is also provided inside the limiting post 92. The heating element 93 in this embodiment is provided with a heating wire, which can heat the medicine in the infusion tube 8 to reduce the irritation of the medicine to the human body and improve the patient's comfort during infusion.
