Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and relates to a monitor, in particular to an anesthesia depth monitor. Background Art

[0002] Since the 1950s, with the in-depth research of anesthesiology and the continuous supplement of theoretical knowledge, the anesthesia operation technology has been continuously improved and perfected. A large number of professionals engaged in the anesthesia specialty have emerged, and the scope of anesthesia work has been extended to clinical anesthesiology, intensive care medicine, first aid and resuscitation medicine, pain diagnosis and treatment, etc. During the anesthesia process, the anesthesia depth and sedation level directly affect the patient's perception of pain and the treatment effect during the subsequent surgery. If the anesthesia depth is too shallow, it is easy to cause adverse reactions such as blood flow, intraoperative awareness, and body movement, interfering with the surgical process. However, too deep anesthesia severely inhibits the functions of various vital organs including the respiratory and circulatory systems, resulting in ischemia, hypoxia, and even brain function damage to the patient, endangering life. Therefore, it is very necessary to monitor the anesthesia depth index during the operation, which is more beneficial to controlling and achieving the best effect with the least amount of anesthetic, and shortening the postoperative recovery time.

[0003] After retrieval, a Chinese patent document discloses an anesthesia depth monitor [Application No.: 202320839903.3; Publication No.: CN 219645699 U]. This anesthesia depth monitor includes an anesthesia depth monitor body. A display panel is arranged on the front of the anesthesia depth monitor body, a wire is arranged on the right side of the anesthesia depth monitor body, and a storage component is arranged on the right side of the anesthesia depth monitor body. The storage component includes a shell fixedly connected to the right side of the anesthesia depth monitor body. For this anesthesia depth monitor, the wire on the right side of the anesthesia depth monitor body is sorted out, and then the wire is placed inside the shell through a through hole. Turning the knob drives the threaded rod to rotate, the rotation of the threaded rod drives the threaded block to move leftward, the leftward movement of the threaded block drives the second clamping plate to move leftward, and the movement of the second clamping plate can cooperate with the first clamping plate to clamp and fix the sorted wire, so as to prevent the messy wire from affecting the patient's comfort as much as possible. Long-term compression can cause pressure injuries, and excessive pulling or dropping on the ground and being stepped on can cause damage, increasing costs.

[0004] Although the wire sorting mechanism disclosed in this patent can clamp and fix the sorted wire in cooperation with the first clamping plate by moving the second clamping plate to prevent the messy wire from affecting the patient's comfort as much as possible, however, this device requires manual sorting of the wire first, the operation is relatively cumbersome, and after the wire sorting and clamping are completed, it may also be scattered due to unexpected situations, the sorting effect is poor, and the monitoring piece cannot be disinfected when not in use, affecting the next use. Summary of the Invention

[0005] The object of the present invention is to address the above problems existing in the prior art and propose an anesthesia depth monitor. The technical problem to be solved by this invention is: how to improve the convenience of signal line arrangement, facilitate disinfection and cleaning, and enhance the practicality of the device.

[0006] The object of the present invention can be achieved by the following technical solutions: An anesthesia depth monitor, comprising a moving base. A support seat is fixedly connected to the upper side of the moving base through a pillar. A monitor body is arranged on the support seat. A winding box is fixed on the support seat. A liquid storage cavity, a winding cavity and a waste liquid cavity are formed in the winding box. A winding drum is arranged in the winding cavity. Rotating shafts are fixed at the front and rear ends of the winding drum. One of the rotating shafts is rotatably connected to the winding cavity, and the other rotating shaft is connected to a conductive component. The conductive component is communicatively connected to the monitor body through a first signal line. A second signal line is connected to the conductive component. The second signal line passes through the winding drum and is connected to a monitoring piece. A torsion spring is fixed between the winding drum and the winding cavity. A partition is fixed in the winding cavity. The second signal line passes through the partition. An annular spray seat is fixed at a position on the right side of the partition in the winding cavity. A plurality of spray heads are fixed on the annular spray seat. A water pump is fixed in the liquid storage cavity. The water pump is communicated with the annular spray seat. A drain port is formed between the waste liquid cavity and the winding cavity. A switch door is hinged to the right side of the winding cavity. An extrusion component and a speed reduction component are arranged in the winding cavity. A transmission component is arranged between the extrusion component and the speed reduction component.

[0007] The working principle of the present invention is as follows: During operation, first, the water pump and the spray seat are used to disinfect and clean the monitoring piece. The generated waste liquid flows into the waste liquid cavity through the drain port. Then, the switch door is opened, and the detection piece is pulled out. Initially, the extrusion component presses the second signal line on the winding drum, and at the same time, the speed reduction component clamps the second signal line. During the pulling process of the second signal line, the speed reduction component releases the second signal line to prevent the second signal line from being difficult to extract, and the extrusion component always maintains the extrusion state of the second signal line to prevent the second signal line from becoming loose. After pulling out to the required length, the second signal line is fixed with tape, and then the monitoring piece is attached to the patient to perform monitoring. After the monitoring is completed, the monitoring piece is removed and the tape is removed. Under the action of the torsion spring, the winding drum automatically winds up. During the winding process, the extrusion component retracts under the action of the second signal line, so that the speed reduction component moves through the transmission component, gradually increasing the clamping force of the speed reduction component on the second signal line. When the monitoring piece enters the winding cavity and is located on the right side of the partition, the clamping force reaches the maximum, preventing the second signal line from moving. The setting of this structure can prevent the winding speed from being too fast and damaging the second signal line, and at the same time can prevent the monitoring piece from hitting the partition to protect the monitoring piece. After the winding is completed, the switch door is closed, and the monitoring piece is cleaned and disinfected by the spray head for convenient use in the next round.

[0008] The extrusion assembly includes a first support cylinder. The upper end of the first support cylinder is fixedly connected to the upper end of the winding cavity. A push rod is slidably connected inside the first support cylinder. A push plate is fixed to the lower end of the push rod. A first slide plate slidably connected to the first support cylinder is fixed to the upper end of the push rod. A first tension spring is fixed between the lower side of the first slide plate and the support cylinder. The speed reduction assembly includes a support rod and a second support cylinder. The support rod is fixedly connected to the lower end of the winding cavity. A lower clamping plate is fixed to the upper end of the support rod. The second support cylinder is fixedly connected to the upper end of the winding cavity. A lifting rod is slidably connected inside the second support cylinder. A second slide plate slidably connected to the second support cylinder is fixed to the upper end of the lifting rod. A first spring is fixed between the lower side of the second slide plate and the second support cylinder. A speed reduction rod is slidably connected inside the lifting rod. An upper clamping plate is fixed to the lower end of the speed reduction rod. A second spring is fixed between the speed reduction rod and the lifting rod. A transmission assembly is arranged between the first slide plate and the second slide plate.

[0009] With the above structure, when winding the second signal wire, the push plate is always pressed tightly above the second signal wire, so that the second signal wire can be prevented from loosening during the winding process. At the same time, the second signal wire pushes the push plate to rise, so that the first slide plate rises. The first slide plate makes the second slide plate descend through the transmission assembly, so that the lifting rod drives the upper clamping plate to descend. Initially, under the action of the second spring, the upper clamping plate will contact the second signal wire, so as to clamp the second signal wire between the upper clamping plate and the lower clamping plate. During the descent of the second slide plate, the second spring is compressed, so that the clamping force of the upper clamping plate gradually increases, thereby reducing the winding speed of the second signal wire. When the monitoring piece enters the winding cavity and is located on the right side of the partition plate, the clamping force reaches the maximum, so that the second signal wire cannot move. The whole process is automated, without the need for additional drive sources and electrical components, with low failure rate and reduced equipment costs.

[0010] The transmission assembly includes a first liquid storage bladder and a second liquid storage bladder. The first liquid storage bladder is arranged inside the first support cylinder and above the first slide plate. The second liquid storage bladder is arranged inside the second support cylinder and above the second slide plate. A communication pipe is fixed between the first liquid storage bladder and the second liquid storage bladder.

[0011] With the above structure, through the mutual extrusion of the first slide plate and the second slide plate on the first liquid storage bladder and the second liquid storage bladder, the coordinated movement between the push plate and the upper clamping plate is realized. Moreover, the transmission structure is simple, which can ensure the compactness of the device, and the transmission resistance is small, ensuring the stability of the device operation.

[0012] The conductive component includes a conductive column and a connecting seat. The connecting seat is fixedly connected to the winding cavity. The conductive column is fixedly connected to the end of one of the rotating shafts. The conductive column extends into the connecting seat and is rotatably connected to the connecting seat. A plurality of annular grooves are formed on the outer periphery of the conductive column. A conductive ring is fixedly arranged inside the connecting seat. The conductive ring is connected to the first signal line. A plurality of conductive parts are arranged on the inner periphery of the conductive ring. The conductive parts extend into the annular grooves.

[0013] With the above structure, during operation, it can not only ensure the winding of the second signal line by the winding drum, but also prevent the first signal line from being wound, so that the transmission of the signal will not be affected by the rotation of the winding drum, improving the practicability of the device.

[0014] The conductive part includes a third support cylinder. The third support cylinder is fixedly connected to the conductive ring. A third spring is fixedly arranged inside the third support cylinder. The other end of the third spring is fixedly connected to a third sliding plate. A telescopic column is fixedly arranged on the lower side of the third sliding plate. The other end of the telescopic column is fixedly connected to a conductive head. A third signal line is fixedly arranged on the inner periphery of the conductive ring. The other end of the third signal line sequentially passes through the third support cylinder and the telescopic column and is connected to the conductive head. The conductive head is located in the annular groove of the conductive column.

[0015] With the above structure, the conductive head is always in contact with the conductive head under the action of the third spring, preventing the occurrence of poor contact after long-term friction between the conductive column and the conduction head due to the rotation of the conductive column, ensuring the stable operation of the device.

[0016] A trash can is arranged on the moving base. A water drainage plate is fixedly arranged inside the trash can. A plurality of water drainage holes are formed on the water drainage plate. A plug is inserted into the water drainage holes. An avoidance groove is formed on the lower side of the water drainage plate. A second tension spring is fixedly arranged in the avoidance groove. The lower end of the second tension spring is fixedly connected to the plug. A drain pipe is fixedly arranged at the lower end of the trash can.

[0017] With the above structure, the medical waste generated during the operation can be placed in the trash can. And when the liquid in the trash can reaches a certain level, under the pressure of the liquid, the plug can be pushed open, so that part of the liquid falls below the water drainage plate, so that there will not be too much liquid in the upper part of the trash can, and at the same time, a part of the liquid will be retained above the trash can. On the one hand, it can prevent too much liquid in the upper part of the trash can from spilling due to factors such as collision and shaking during the movement. On the other hand, when dumping the garbage, the part of the liquid retained in the trash can can make the garbage easier to pour out, reducing the cleaning difficulty.

[0018] A liquid pump and an annular liquid delivery seat are fixed at the lower end of the support seat, one end of the liquid pump is connected to the waste liquid chamber, and the other end of the liquid pump is connected to the annular liquid delivery seat, the lower side of the annular liquid delivery seat is rotatably connected to an annular liquid outlet seat, the lower side of the annular liquid outlet seat is fixed with a first liquid delivery pipe, a second liquid delivery pipe is fixed on the trash can, the first liquid delivery pipe and the second liquid delivery pipe are connected by a quick connection mechanism, and a plurality of spray heads are distributed in an annular manner inside the trash can, and the spray heads are connected to the second liquid delivery pipe through pipelines.

[0019] By adopting the above structure, the waste liquid in the waste liquid chamber can be delivered to the annular liquid delivery seat by using a liquid pump, and then the liquid is delivered to the second liquid delivery pipe through the annular liquid outlet seat and the first liquid delivery pipe, and finally sprayed out through the spray head to perform preliminary disinfection on the inside of the trash can. The setting of this structure can improve the utilization rate of resources, and at the same time can reduce the growth of bacteria inside the trash can to ensure environmental safety.

[0020] The quick-connect mechanism includes a quick-connect seat, a quick-connect cavity is provided in the quick-connect seat, the first liquid delivery tube is connected to the quick-connect cavity, an insertion port and an inclined surface are provided at one end of the quick-connect cavity away from the first liquid delivery tube, a positioning cylinder is fixed inside the quick-connect cavity, a fourth spring located outside the positioning cylinder is fixed inside the quick-connect cavity, a plurality of positioning rings are provided between the other end of the fourth spring and the inclined surface, the second liquid delivery tube is inserted into the positioning cylinder after passing through the insertion port and the positioning ring in sequence, an unlocking port is provided on the quick-connect seat near the inclined surface, and an unlocking component is provided on the unlocking port.

[0021] With the above structure, when working, the second liquid delivery tube can be inserted into the positioning cylinder after passing through the plug interface and the positioning ring in sequence. During the insertion process, the positioning ring can be aligned so that the second liquid delivery tube can be inserted. After the insertion is completed, the positioning ring is tilted under the action of the fourth spring, thereby locking the second liquid delivery tube to ensure the stability of the connection. When the trash can needs to be disassembled, the unlocking assembly is inserted into the quick-connect cavity through the unlocking port, and the positioning ring is aligned, and the second liquid delivery tube can be pulled out. It is simple and convenient. The setting of this structure can realize the rapid installation and disassembly of the trash can, which is convenient for the later replacement of garbage in the trash can.

[0022] The unlocking assembly includes a first elastic assembly, which is fixed on the quick-connect seat, a pressing plate is fixed on the other end of the first elastic assembly, an unlocking rod is slidably connected to the pressing plate, and a fifth spring is fixed between the unlocking rod and the pressing plate.

[0023] With the above structure, initially, the unlocking rod is located in the unlocking port and contacts the right side of the unlocking port. When unlocking, the pressing plate is pushed to cause the pressing plate to descend, driving the unlocking rod to descend. While the unlocking rod descends, it moves to the left under the action of the inclined surface, thereby straightening the positioning ring and realizing the unlocking operation.

[0024] A plurality of cavities are formed in the outer periphery of the annular liquid outlet seat. A plurality of second elastic components are fixed inside the cavities. The other end of the second elastic component is fixed with an arc-shaped block. A plurality of arc-shaped grooves are formed in the inner periphery of the annular liquid supply seat, and the arc-shaped blocks are matched with the arc-shaped grooves.

[0025] With the above structure, while ensuring stable infusion, the trash can can move in a circular motion on the moving base to meet different usage requirements. After moving, the arc-shaped blocks and the arc-shaped grooves can be used to position the trash can to prevent it from shaking easily during use and improve the comfort of use.

[0026] Compared with the prior art, the present anesthetic depth monitor has the following advantages: 1. During operation, first, the monitoring piece is disinfected and cleaned by using a water pump and a spraying seat. The generated waste liquid flows into the waste liquid cavity through the liquid discharge port. Then, the switch door is opened and the detection piece is pulled out. Initially, the pressing component presses the second signal line on the winding reel tightly, and at the same time, the speed reduction component clamps the second signal line. During the pulling process of the second signal line, the speed reduction component loosens the second signal line to prevent the second signal line from being difficult to extract, and the pressing component always maintains the pressing state on the second signal line to prevent the second signal line from becoming loose. After pulling out to the required length, the second signal line is fixed with tape. Then, the monitoring piece is attached to the patient's body to start monitoring. After the monitoring is completed, the monitoring piece is removed and the tape is removed. Under the action of the torsion spring, the winding reel automatically winds up. During the winding process, the pressing component retracts under the action of the second signal line, so that the speed reduction component moves through the transmission component, and gradually increases the clamping force of the speed reduction component on the second signal line. When the monitoring piece enters the winding cavity and is located on the right side of the partition plate, the clamping force reaches the maximum, so that the second signal line cannot move. The setting of this structure can prevent the winding speed from being too fast and damaging the second signal line, and at the same time can prevent the monitoring piece from hitting the partition plate to protect the monitoring piece. After the winding is completed, the switch door is closed, and the monitoring piece is cleaned and disinfected by using the spray head for convenient use in the next round.

[0027] 2. When the second signal wire is being wound up, the pressing plate is always tightly pressed above the second signal wire, so that the second signal wire will not become loose during the winding process. At the same time, the second signal wire pushes the pressing plate upward, causing the first sliding plate to rise. The first sliding plate drives the second sliding plate to descend through the transmission component, and the lifting rod drives the upper clamping plate to descend. Initially, under the action of the second spring, the upper clamping plate will come into contact with the second signal wire, thereby clamping the second signal wire between the upper clamping plate and the lower clamping plate. During the descent of the second sliding plate, the second spring is compressed, increasing the clamping force of the upper clamping plate gradually, thus reducing the winding speed of the second signal wire. When the monitoring piece enters the winding cavity and is located on the right side of the partition plate, the clamping force reaches the maximum, making the second signal wire unable to move. The whole process is automated, without the need for additional drive sources and electrical components, with a low failure rate and reduced equipment costs.

[0028] 3. During operation, it can not only ensure the winding of the second signal wire by the winding drum, but also prevent the first signal wire from being entangled, so that the signal transmission will not be affected by the rotation of the winding drum, improving the practicality of the device.

[0029] 4. The medical waste generated during the operation can be placed in the trash can. And when the liquid in the trash can reaches a certain level, under the pressure of the liquid, the sealing plug can be pushed open, allowing some liquid to fall below the draining plate. As a result, there will not be too much liquid in the upper part of the trash can, while a part of the liquid will be retained above the trash can. On the one hand, it can prevent too much liquid in the upper part of the trash can from spilling due to factors such as collision and shaking during movement. On the other hand, when dumping the garbage, the part of the liquid retained in the trash can can make it easier to pour out the garbage, reducing the cleaning difficulty.

[0030] 5. The waste liquid in the waste liquid cavity can be sent into the annular liquid supply seat by using a liquid pumping pump, and then through the annular liquid outlet seat and the first liquid supply pipe, the liquid is sent into the second liquid supply pipe, and finally sprayed out through the spray head to conduct a preliminary disinfection of the inside of the trash can. The setting of this structure can improve the utilization rate of resources, and at the same time can reduce the growth of bacteria inside the trash can, ensuring environmental safety.

Detailed implementation manners

[0044] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0045] As Figures 1 - 12As shown in the figure, this anesthesia depth monitor includes a mobile base 1. A support base 3 is fixedly connected to the upper side of the mobile base 1 through a support column 2. A monitor body 4 is arranged on the support base 3. A winding box 7 is fixed on the support base 3. A liquid storage cavity 15, a winding cavity 16 and a waste liquid cavity 17 are formed in the winding box 7. A winding drum 19 is arranged in the winding cavity 16. Rotating shafts are fixed at the front and rear ends of the winding drum 19. One of the rotating shafts is rotatably connected to the winding cavity 16, and the other rotating shaft is connected to a conductive component. The conductive component is communicatively connected to the monitor body 4 through a first signal line 27. A second signal line 6 is connected to the conductive component. The second signal line 6 passes through the winding drum 19 and is connected to a monitoring piece 5. A torsion spring 29 is fixed between the winding drum 19 and the winding cavity 16. A partition 21 is fixed in the winding cavity 16. The second signal line 6 passes through the partition 21. An annular spray seat 23 is fixed at a position on the right side of the partition 21 in the winding cavity 16. A plurality of spray heads 24 are fixed on the annular spray seat 23. A water pump 22 is fixed in the liquid storage cavity 15. The water pump 22 is communicated with the annular spray seat 23. A drain port 18 is formed between the waste liquid cavity 17 and the winding cavity 16. A switch door 25 is hinged on the right side of the winding cavity 16. An extrusion component and a speed reduction component are arranged in the winding cavity 16. A transmission component is arranged between the extrusion component and the speed reduction component.

[0046] During operation, first, the water pump 22 and the spray seat are used to disinfect and clean the monitoring piece 5. The generated waste liquid flows into the waste liquid cavity 17 through the drain port 18. Then, the switch door 25 is opened and the detection piece is pulled out. Initially, the extrusion component presses the second signal line 6 on the winding drum 19, and at the same time, the speed reduction component clamps the second signal line 6. During the pulling process of the second signal line 6, the speed reduction component loosens the second signal line 6 to prevent the second signal line 6 from being difficult to pull out, and the extrusion component always maintains the extrusion state of the second signal line 6 to prevent the second signal line 6 from becoming loose. After pulling out to the required length, the second signal line 6 is fixed with tape. Then, the monitoring piece 5 is attached to the patient's body to start monitoring. After the monitoring is completed, the monitoring piece 5 is removed and the tape is removed. Under the action of the torsion spring 29, the winding drum 19 automatically winds up. During the winding process, the extrusion component retracts under the action of the second signal line 6, so that the speed reduction component moves through the transmission component, gradually increasing the clamping force of the speed reduction component on the second signal line 6. When the monitoring piece 5 enters the winding cavity 16 and is on the right side of the partition 21, the clamping force reaches the maximum, making the second signal line 6 unable to move. The setting of this structure can prevent the winding speed from being too fast and damaging the second signal line 6, and at the same time can prevent the monitoring piece 5 from hitting the partition 21 to protect the monitoring piece 5. After the winding is completed, the switch door 25 is closed, and the spray heads 24 are used to clean and disinfect the monitoring piece 5 for the next use.

[0047] The extrusion assembly includes a first support cylinder 36. The upper end of the first support cylinder 36 is fixedly connected to the upper end of the winding cavity 16. A push rod 37 is slidably connected inside the first support cylinder 36. A push plate 38 is fixed to the lower end of the push rod 37. A first sliding plate 39 slidably connected to the first support cylinder 36 is fixed to the upper end of the push rod 37. A first tension spring 40 is fixed between the lower side of the first sliding plate 39 and the support cylinder. The speed reduction assembly includes a support rod and a second support cylinder 43. The support rod is fixedly connected to the lower end of the winding cavity 16. A lower clamping plate 20 is fixed to the upper end of the support rod. The second support cylinder 43 is fixedly connected to the upper end of the winding cavity 16. A lifting rod 46 is slidably connected inside the second support cylinder 43. A second sliding plate 45 slidably connected to the second support cylinder 43 is fixed to the upper end of the lifting rod 46. A first spring 47 is fixed between the lower side of the second sliding plate 45 and the second support cylinder 43. A speed reduction rod 49 is slidably connected inside the lifting rod 46. An upper clamping plate 50 is fixed to the lower end of the speed reduction rod 49. A second spring 48 is fixed between the speed reduction rod 49 and the lifting rod 46. A transmission assembly is provided between the first sliding plate 39 and the second sliding plate 45.

[0048] With the above structure, when the second signal line 6 is wound, the push plate 38 is always pressed tightly above the second signal line 6, so that the second signal line 6 can be prevented from loosening during the winding process. At the same time, the second signal line 6 pushes the push plate 38 to rise, so that the first sliding plate 39 rises. The first sliding plate 39 makes the second sliding plate 45 descend through the transmission assembly, so that the lifting rod 46 drives the upper clamping plate 50 to descend. Initially, under the action of the second spring 48, the upper clamping plate 50 will contact the second signal line 6, so as to clamp the second signal line 6 between the upper clamping plate 50 and the lower clamping plate 20. During the descent of the second sliding plate 45, the second spring 48 is compressed, so that the clamping force of the upper clamping plate 50 gradually increases, thereby reducing the winding speed of the second signal line 6. When the monitoring piece 5 enters the winding cavity 16 and is located on the right side of the partition plate 21, the clamping force reaches the maximum, so that the second signal line 6 cannot move. The whole process is automated, without the need for additional drive sources and electrical components, with low failure rate and reduced equipment costs.

[0049] The transmission assembly includes a first liquid storage bladder 41 and a second liquid storage bladder 44. The first liquid storage bladder 41 is arranged inside the first support cylinder 36 and above the first sliding plate 39. The second liquid storage bladder 44 is arranged inside the second support cylinder 43 and above the second sliding plate 45. A communication pipe 42 is fixed between the first liquid storage bladder 41 and the second liquid storage bladder 44.

[0050] With the above structure, through the mutual extrusion of the first sliding plate 39 and the second sliding plate 45 on the first liquid storage bag 41 and the second liquid storage bag 44, the cooperative movement between the pressing plate 38 and the upper clamping plate 50 is realized. Moreover, the transmission structure is simple, which can ensure the compactness of the device, and the transmission resistance is small, ensuring the stability of the device operation.

After moving, the trash can 14 can be positioned by utilizing the cooperation of the arc block 68 and the arc groove 69 to prevent the trash can 14 from shaking easily during use, thereby improving the comfort of use.

[0065] Working principle of the present invention: During operation, first, the water pump 22 and the spray seat are used to disinfect and clean the monitoring piece 5. The generated waste liquid flows into the waste liquid cavity 17 through the drain port 18. Then, the switch door 25 is opened, and the test piece is pulled out. Initially, the pressing component presses the second signal line 6 on the winding drum 19 tightly, and at the same time, the speed reduction component clamps the second signal line 6. During the pulling process of the second signal line 6, the speed reduction component releases the second signal line 6 to prevent the second signal line 6 from being difficult to extract, and the pressing component always maintains the pressing state on the second signal line 6 to prevent the second signal line 6 from becoming loose. After pulling out to the required length, the second signal line 6 is fixed with tape. Then, the monitoring piece 5 is attached to the patient's body to start monitoring. After the monitoring is completed, the monitoring piece 5 is removed and the tape is removed. Under the action of the torsion spring 29, the winding drum 19 automatically winds up. During the winding process, the pressing plate 38 always presses tightly above the second signal line 6, so that the second signal line 6 can be prevented from becoming loose during the winding process. At the same time, the second signal line 6 pushes the pressing plate 38 to rise, so that the first sliding plate 39 rises. The first sliding plate 39 drives the second sliding plate 45 to descend through the transmission component, so that the lifting rod 46 drives the upper clamping plate 50 to descend. Initially, under the action of the second spring 48, the upper clamping plate 50 will contact the second signal line 6, and thus the second signal line 6 is clamped between the upper clamping plate 50 and the lower clamping plate 20. During the descent of the second sliding plate 45, the second spring 48 is compressed, so that the clamping force of the upper clamping plate 50 gradually increases, thereby reducing the winding speed of the second signal line 6. When the monitoring piece 5 enters the winding cavity 16 and is located on the right side of the partition plate 21, the clamping force reaches the maximum, so that the second signal line 6 cannot move. The setting of this structure can prevent the winding speed from being too fast and damaging the second signal line 6, and at the same time can prevent the monitoring piece 5 from hitting the partition plate 21 to protect the monitoring piece 5. After the winding is completed, the switch door 25 is closed, and the monitoring piece 5 is cleaned and disinfected by the spray head 24 for convenient use in the next step; When installing the trash can 14, the second liquid delivery pipe 13 can be inserted into the positioning cylinder 60 after passing through the insertion interface and the positioning ring 58 in sequence. During the insertion process, the positioning ring 58 can be aligned so that the second liquid delivery pipe 13 can be inserted. After the insertion is completed, under the action of the fourth spring 59, the positioning ring 58 is tilted, thereby locking the second liquid delivery pipe 13 to ensure the stability of the connection. The medical waste generated during the operation can be placed in the trash can 14. And when the liquid in the trash can 14 reaches a certain level, under the pressure of the liquid, the sealing plug 55 can be pushed open, so that part of the liquid falls below the water drainage plate 51. Thus, while there will not be too much liquid in the upper part of the trash can 14, a part of the liquid will also be retained above the trash can 14. On the one hand, it can prevent too much liquid in the upper part of the trash can 14 from spilling due to factors such as collision and shaking during the movement. On the other hand, when dumping the garbage, the part of the liquid retained in the trash can 14 can make the garbage easier to pour out, reducing the cleaning difficulty. And after placing the garbage, the liquid waste in the liquid waste chamber 17 can be sent into the annular liquid delivery seat 9 by using the liquid extraction pump 8, and then through the annular liquid outlet seat 10 and the first liquid delivery pipe 11, the liquid is sent into the second liquid delivery pipe 13, and finally sprayed out through the spray head 52 to conduct a preliminary disinfection of the inside of the trash can 14. And the trash can 14 can move in a circular motion on the moving base 1 to meet different usage requirements. And after moving, the cooperation of the arc-shaped block 68 and the arc-shaped groove 69 can be used to position the trash can 14 to prevent it from shaking easily during the use of the trash can 14.

[0066] In summary, through the settings of structures such as the winding drum 19, the clamping assembly, and the speed reduction assembly, the function of improving the convenience of signal line arrangement, facilitating disinfection and cleaning, and enhancing the practicality of the device is realized.
