Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a monitoring device for an arterial compressor of a critically ill patient. Background Art

[0002] When measuring the central venous pressure of critically ill patients, first place a tube in the jugular vein, connect the infusion pump filled with normal saline to the internal tube, fix it at the fourth rib of the mid-axillary line, and keep the infusion tube perpendicular to the body surface. Use a ruler to measure the distance between the liquid level in the infusion pump and the mid-axillary line to obtain the central venous pressure. After the test is completed, the tube needs to be removed, and finally a compressor is used to press.

[0003] However, the traditional compressor has the following disadvantages during use:

[0004] Prolonged pressing causes the tissue around the pressing area to harden, and the compressor cannot provide relief during the pressing process. At the same time, the skin around the pressing area cannot be cleaned, making bacterial infection more likely to occur. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the existing technology that long-term pressing causes hardening of the tissue around the pressing part, and the compressor cannot relieve the pressure during the pressing process. At the same time, the skin around the pressing part cannot be cleaned, which is prone to bacterial infection. A monitoring device for arterial compressors for critically ill patients is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A monitoring device for an arterial compressor of a critically ill patient, comprising:

[0008] A connecting belt with a rectangular hole on its top and guide rails on both sides. Two sliding blocks are slidably sleeved on the guide rails, and a connecting frame is fixedly connected between the two sliding blocks.

[0009] A support rod passes through the cover plate rotatably arranged on the connection frame, and a first pressing block for pressing the lower end of the artery is fixed at the bottom end of the support rod;

[0010] An electric push rod is fixedly mounted on one side of the support rod, and its output end is connected to a second pressure block for pressing the upper end of the artery. A pressure sensor is provided at the bottom of the second pressure block. The pressure sensor and the electric push rod are electrically connected to an external controller.

[0011] A massage assembly comprising a massage ball and a cleaning roller arranged around the first pressing block and the second pressing block, wherein a replaceable wet wipe is wound around the outer wall of the cleaning roller;

[0012] A driving assembly is provided on one side of the support rod, driving the massage balls and the cleaning roller to rotate around the pressing block;

[0013] The two ends of the connecting belt are respectively provided with a first Velcro and a second Velcro that cooperate with each other. The pressure sensor monitors the pressing force in real time and adjusts the extension and retraction of the electric push rod through the controller. The cleaning roller wipes the skin with wet wipes when rotating to prevent infection.

[0014] As a further improvement of the above technical solution:

[0015] One end of the cover is hinged to one of the sliding blocks through a rotating seat, and the other end is clamped to the other sliding block through a limiting block. The limiting block is provided with a limiting structure that cooperates with the arc-shaped opening at the end of the cover.

[0016] The drive assembly includes:

[0017] A gear disc rotatably sleeved on the outer wall of the electric push rod;

[0018] a gear meshing with the toothed disc and driven by a motor;

[0019] The sleeve rod is fixed to the bottom of the toothed disc and connected to the sliding rod. The sliding rod drives the massage ball and the cleaning roller on one side to move through the sliding frame in the sliding groove.

[0020] The drive assembly further includes:

[0021] A driving disc, rotatably sleeved on the outer wall of the support rod and linked to the gear disc through a clamping column;

[0022] The fixed rod is fixed to the bottom of the driving disk and drives the massage balls and the cleaning roller on the other side to rotate.

[0023] The bottoms of the sliding rod and the fixed rod are respectively connected to the cleaning roller via a rotating column, and the cleaning roller forms a rotatable structure with the rotating column via a connecting plate.

[0024] A rectangular opening is provided on the outer wall of the cleaning roller, and a pressure strip fixed by a clamping strip is provided in the rectangular opening. The two ends of the wet wipes are pressed into the rectangular opening by the pressure strip to achieve quick replacement. Disposable rubber sleeves are provided on the bottom of the first pressing block and the second pressing block. The rubber sleeves are made of medical silicone. A protective cover is provided on the outside of the gear disk and the drive disk. The protective cover is fixed to the outer wall of the connecting frame. A turntable is fixed on the top of the support rod. Rotating the turntable can make the electric push rod deviate from the connecting frame to open the cover. The controller integrates a blood oxygen monitoring module. When the pressure sensor detects that the pressing force exceeds the threshold or the blood oxygen value is abnormal, an alarm is triggered.

[0025] Beneficial effects: In the present invention, the monitoring device for an arterial compressor for critically ill patients can be conveniently fixed to the patient through the first and second Velcro strips on the connecting belt, thereby achieving precise positioning and pressing of the artery. During use, the design of the connecting frame and the sliding block enables the device to adapt to the body shapes and puncture sites of different patients, thereby improving the applicability and stability of the device. At the same time, the first pressing block under the support rod and the second pressing block driven by the electric push rod can achieve simultaneous pressing of the upper and lower ends of the artery, ensuring the pressing effect. The provision of the rubber sleeve increases the comfort and sealing of the pressing, thereby avoiding damage to the skin during the pressing process.

[0026] In the present invention, the monitoring device for an arterial compression device for critically ill patients can monitor the compression force in real time through a pressure sensor provided at the bottom of the second compression block, and transmit the data to an external controller. The controller can automatically adjust the extension length of the electric push rod based on the monitored data, thereby achieving precise control of the compression force, which not only improves the accuracy and stability of the compression but also reduces the workload of medical staff.

[0027] In the present invention, the monitoring device for an arterial compressor for critically ill patients can massage and clean the surrounding skin during the pressing process through the setting of a massage ball and a cleaning roller. The massage ball can move on the skin through the drive assembly, which promotes blood circulation and relieves muscle tension. The cleaning roller can wipe the skin with a wet wipe during the movement, which can remove dirt and sweat on the skin and keep the skin clean and dry. This not only improves the patient's comfort, but also helps prevent complications such as skin infections and pressure sores. By pressing the pressure strip outward, the card strip can be disengaged from the card slot, making it easy to replace the wet wipes. After the replacement is completed, the card strip can be used to fix it and it can continue to be used. This simplifies the replacement process of the wet wipes and improves the ease of use and practicality of the device.

[0028] In the present invention, the monitoring device for an arterial compressor for critically ill patients facilitates medical personnel to observe the compression situation through a reversible cover. When observation is required, the limit block and the turntable can be rotated to flip the cover upward and move it outside the connection frame, thereby exposing the compression site. After the observation is completed, the cover is closed and the turntable is rotated to move the electric push rod to the compression site to continue compression. This not only facilitates the operation of medical personnel, but also improves the flexibility and practicality of the device.

[0029] In the present invention, an electric push rod is used in conjunction with a pressure sensor to automatically adjust the pressing force according to actual needs, which not only avoids damage caused by excessive pressing but also ensures sufficient pressing effect. At the same time, the device also integrates a massage ball and a cleaning roller, which can massage and clean the surrounding skin during the pressing process, effectively promoting blood circulation and reducing the occurrence of skin complications.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Example 1

[0040] Reference Figure 1-Figure 7 , a monitoring device, comprising: a connecting belt 1, a rectangular hole 2 is provided on the top of the connecting belt 1 for easy observation and operation, and guide rails are formed on both sides thereof for sliding of the sliding block 5. Two sliding blocks 5 located on the guide rails are slidably sleeved on the connecting belt 1, and a same connecting frame 6 is fixed between the two sliding blocks 5, and the connecting frame 6 is used to fix and support the subsequent pressing and monitoring structure. A cover plate 7 is provided on the connecting frame 6, and a support rod 9 is provided through and rotated on the top of the cover plate 7, and a first pressing block 12 for pressing the lower end of the artery is fixed at the bottom end of the support rod 9. This design allows the first pressing block 12 to perform preliminary pressing on the lower end of the artery when the connecting belt 1 is tied.

[0041] A first Velcro 3 is provided on the outside of one end of the connecting belt 1, and a second Velcro 4 used in conjunction with the first Velcro 3 is provided on the inside of the other end. Through the adhesion of the Velcro, the connecting belt 1 can be conveniently tied to the patient.

[0042] An electric push rod 11 is provided on one side of the support rod 9, and a second pressure block 14 for pressing the upper end of the artery is fixedly provided at the output end of the electric push rod 11. A pressure sensor 33 for monitoring the pressure intensity is provided at the bottom of the second pressure block 14. This design can monitor the pressure intensity in real time to ensure the accuracy and safety of the pressure. The pressure sensor 33 and the electric push rod 11 are both connected to an external controller via wires. The controller can adjust the extension or retraction of the electric push rod 11 according to the feedback from the pressure sensor 33 to maintain an appropriate pressure intensity. Its monitoring principle is the same as that used in patent document CN118285934A, and also includes a main control module, a data conversion unit, a judgment control unit, and an early warning module. The pressure sensor in contact with the puncture point automatically detects the pressure at the contact point and, through a converter, converts the pressure value into a specific numerical value, which is then displayed on the screen. When the device is turned on, a timer also starts to record the compression time. The pressure value and compression time will then appear on the screen. This monitoring device quantifies the pressure into a specific numerical value. Through an information transmission system, individualized patient information can be transmitted to the screen, displaying each patient's real-time pressure and compression time, whether after treatment or after an examination. By limiting the pressure intensity and compression time, a real-time alarm can be generated, alerting medical staff to provide timely intervention. Also included is a blood oxygen monitoring device, connected to the main control module, for monitoring arterial oxygen levels during compression of the puncture point, where arterial oxygen levels include at least oxygen saturation. The blood oxygen monitor is also attached to the pressure sensor, but it is independent of the baroreceptor and exists to monitor arterial oxygen levels to prevent vascular occlusion. When the alarm value is reached, an alarm sounds, allowing the patient to call medical staff for appropriate intervention.

[0043] In order to improve the comfort of the patient, the bottom ends of the first pressing block 12 and the second pressing block 14 are both covered with a rubber sleeve 13. The rubber sleeve 13 is soft and has a certain elasticity, which can reduce the pressure on the patient's skin. At the same time, the rubber sleeve 13 is a disposable product to ensure that there will be no cross-infection of viruses during use by each patient.

[0044] In addition, massage balls 28 and cleaning rollers 27 are provided on the outside of the first pressing block 12 and the second pressing block 14 for massaging the surrounding skin. A wet wipe 41 for skin cleaning is fixedly wrapped around the outer wall of the cleaning roller 27. This design allows for simultaneous massage and cleaning of the skin, helping to promote blood circulation and keep the skin clean, while effectively preventing hardening of the skin tissue around the pressing area.

[0045] To achieve the rotation of massage balls 28 and cleaning rollers 27, a drive assembly is installed on one side of support rod 9. A connecting frame 19 is fixed between support rod 9 and electric push rod 11. The drive assembly specifically includes a geared disc 20 that rotatably fits around the outer wall of electric push rod 11. A motor 22 is fixed to the top of connecting frame 19. The output end of motor 22 extends to the bottom of connecting frame 19 and is fixedly mounted with a gear 21 that meshes with geared disc 20. When motor 22 is activated, it drives gear 21 to rotate, thereby driving geared disc 20.

[0046] A sleeve rod 24 is fixedly provided at the bottom of the toothed disc 20, and a sliding rod 26 is slidably provided at the bottom end of the sleeve rod 24. A sliding groove 32 is formed at the top of the second pressing block 14, and a sliding frame 34 is slidably provided in the sliding groove 32. One end of the sliding frame 34 is fixedly connected to the sliding rod 26. In this way, when the electric push rod 11 is extended, it can drive the massage balls 28 and cleaning rollers 27 on one side to contact the surrounding skin. When the toothed disc 20 rotates, the sliding frame 34 can drive the sliding rod 26 to slide up and down within the sleeve rod 24, thereby driving the massage balls 28 and cleaning rollers 27 below the sliding rod 26 to contact and massage and clean the surrounding skin.

[0047] Meanwhile, a drive disc 23 is rotatably mounted on the outer wall of the support rod 9. The outer wall of the drive disc 23 is formed with multiple grooves 30. The bottom of the toothed disc 20 is fixed with multiple latches 31 that cooperate with the grooves 30. When the toothed disc 20 rotates, the latches 31 and the grooves 30 drive the drive disc 23 to rotate. A fixed rod 25 is fixed to the bottom of the drive disc 23. Another massage ball 28 is fixed to the bottom of the fixed rod 25, and another cleaning roller 27 is connected to the fixed rod 25. This design allows the two massage balls 28 and two cleaning rollers 27 to rotate simultaneously, providing a comprehensive massage and cleansing effect on the surrounding skin.

[0048] The outer walls of the bottom ends of the fixed rod 25 and the sliding rod 26 are both rotatably provided with a rotating column 35, and the outer wall fixed sleeve of the rotating column 35 is provided with a connecting plate 36, and the cleaning roller 27 is rotatably provided at the other end of the connecting plate 36. This design allows the cleaning roller 27 to rotate stably and roll on the skin, and the wet wipes 41 can clean it during the rolling process without manual cleaning.

[0049] This application can be used in the field of medical auxiliary equipment, and can also be used in other fields applicable to this application.

[0050] Example 2

[0051] refer to Figure 1-Figure 7Improved on the basis of Example 1: A monitoring device for an arterial compressor in a critically ill patient, applied to the field of medical assistive devices. To facilitate the replacement of wet wipes 41, a rectangular opening 37 is defined on the outer wall of the cleaning roller 27. Slots 38 are defined on both sides of the inner wall of the rectangular opening 37. A pressure strip 39 is disposed within the rectangular opening 37. Two clips 40 are fixedly mounted at the bottom of the pressure strip 39, engaging with the slots 38. Both ends of the wet wipe 41 are located between the pressure strip 39 and the rectangular opening 37. When the wet wipe 41 needs to be replaced, the pressure strip 39 is simply pressed outward to disengage the clips 40 from the slots 38, allowing the wet wipe 41 to be conveniently replaced. After replacement, the clips 40 are then secured.

[0052] A rotating seat 8 is fixedly provided on the top of one of the sliding blocks 5, and the cover plate 7 is rotatably arranged in the rotating seat 8. The other end of the cover plate 7 is engaged with the sliding block 5 to realize the flipping function of the cover plate 7. A rotating rod 15 is rotatably provided on the top of the other sliding block 5, and a limit block 16 is fixedly provided on the top of the rotating rod 15. The outer wall of the limit block 16 is provided with a first arc-shaped opening 17 adapted to the cover plate 7, and the top of the cover plate 7 is provided with a second arc-shaped opening 18 adapted to the limit block 16. By rotating the limit block 16, the first arc-shaped opening 17 and the second arc-shaped opening 18 can be made to correspond to each other, and the cover plate 7 can be flipped upward. In this way, after pressing, the cover plate 7 can be opened to observe the pressing situation. When the pressing effect is not good, the cover plate 7 can be closed again and the pressing can be continued, so that a second pressing can be performed accurately. In addition, a turntable 10 is fixed to the top of the support rod 9, which can drive the support rod 9 to rotate, and can drive the electric push rod 11 to move to the outside of the connecting frame 6, so as to avoid the electric push rod 11 from colliding with the inner wall of the connecting frame 6 during the opening of the cover 7.

[0053] In order to protect the gear disc 20 and the driving disc 23 , a protective cover 29 for protecting the gear disc 20 and the driving disc 23 is fixedly provided on the outer wall of the connecting frame 19 .

[0054] When in use, the connecting frame 6 is placed on the puncture site so that the two rubber sleeves 13 are located on the same artery and the puncture needle is located between the two rubber sleeves 13, and the connecting belt 1 is tied to the patient using the first Velcro 3 and the second Velcro 4 at both ends of the connecting belt 1. During the tying process, the rubber sleeve 13 under the support rod 9 is used to press the lower end of the artery, and then the electric push rod 11 is started to extend. The extension of the electric push rod 11 can drive the second pressure block 14 to move downward, and the downward movement of the second pressure block 14 can press the upper end of the artery. At the same time, the blood oxygen monitor is worn on the finger and cooperated with the pressure sensor 33 to monitor the pressing force. When the pressing force is small, the controller controls the electric push rod 11 to continue to extend, otherwise the electric push rod 11 is controlled to retract. At the same time, the electric push rod 11 drives the second pressure block 14 to move downward. In the process, the sliding frame 34 in the slide groove 32 can also drive the sliding rod 26 to move downward in the sleeve rod 24, driving the massage ball 28 and the cleaning roller 27 under the sliding rod 26 to contact the surrounding skin;

[0055] During the pressing process, the motor 22 is started, and the motor 22 can drive the gear 21 to rotate. The rotation of the gear 21 can drive the gear plate 20 to rotate. The rotation of the gear plate 20 can drive the sleeve rod 24 to rotate around the electric push rod 11. At the same time, during the rotation of the gear plate 20, the driving disc 23 can be driven to rotate through the clamping column 31 and the groove 30. The rotation of the driving disc 23 can drive the fixed rod 25 to rotate. The rotation of the sleeve rod 24 can drive the sliding rod 26 to rotate. During the rotation of the sliding rod 26 and the fixed rod 25, the massage ball 28 can be driven to move. During the movement of the massage ball 28, the massage ball 28 massages the surrounding skin. At the same time, it can drive the cleaning roller 27 to move, so that the cleaning roller 27 rolls on the surrounding skin to clean the skin.

[0056] When the wet wipes 41 need to be replaced, the pressure strip 39 is pressed outward to disengage the clamping strip 40 from the clamping slot 38, and then the wet wipes 41 are replaced. After the replacement is completed, the clamping strip 40 is used to fix it.

[0057] When the pressing time is up, the limit block 16 can be rotated to make the first arc-shaped opening 17 correspond to the second arc-shaped opening 18. At this time, the cover 7 can be flipped upward, and the turntable 10 can be rotated at the same time. The rotation of the turntable 10 can drive the support rod 9 to rotate. During the rotation of the support rod 9, the electric push rod 11 can be driven to move through the connecting frame 19, so that the electric push rod 11 moves outside the connecting frame 6, so that the electric push rod 11 will not conflict with the connecting frame 6 during the flipping process of the cover 7. After opening, the pressing situation can be observed. If the situation is not good, the cover 7 can be closed again, and the turntable 10 can be rotated to drive the electric push rod 11 to move to the pressing position and continue pressing.

[0058] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric push rod 11, motor 22 and pressure sensor 33 are commonplace, and are conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0059] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
