AI Technical Summary
Existing renal biopsy compression hemostasis structures cannot regulate the patient's breathing patency, resulting in significant fluctuations at the abdominal puncture site, which can easily cause secondary damage to the puncture site. Furthermore, they cannot cope with the sudden bloating of the abdomen when the patient sneezes or coughs, leading to unsuitable adjustments in the compression force.
A renal puncture compression hemostasis structure was designed, including a compression table, fixing bolts, compression mechanism, ventilation mechanism, amplitude measuring mechanism, and pressure control mechanism. The amplitude measuring mechanism detects the rise and fall of the patient's abdomen and dynamically adjusts the ventilation pressure and compression force. The positive pressure component and the ring column air bag provide flexible support to ensure airway patency and adaptive adjustment of compression force.
It achieves the goal of keeping the airway open during the patient's breathing process, reducing the fluctuation of the abdominal puncture site, reducing the risk of secondary bleeding, and improving the safety and efficiency of compression hemostasis, especially effectively adjusting the pressure when the patient sneezes or coughs.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of pressure hemostasis technology, specifically referring to a renal puncture pressure hemostasis structure. Background Technology
[0002] Kidney biopsy, medically termed renal biopsy, is used when a patient presents with nephrotic syndrome. The pathological types can include minimal change disease, mild change disease, mild mesangial proliferative nephropathy, membranous nephropathy, membranoproliferative glomerulonephritis, and focal segmental sclerosis, among others. These different pathological types have significantly different treatment plans and prognoses. After the kidney biopsy, pressure is applied to the puncture site to stop bleeding, typically requiring continuous pressure for 6 to 8 hours to achieve hemostasis.
[0003] The existing renal biopsy compression hemostasis structures have the following problems:
[0004] Existing renal puncture compression hemostasis structures do not have the function of regulating the patient's breathing patency. Patients breathe unevenly during sleep, causing large fluctuations in the abdominal puncture site, which in turn causes pressure fluctuations in the kidney and surrounding tissues, easily causing secondary damage to the puncture site. Furthermore, traditional structures cannot adaptively adjust the compression force when the patient suddenly sneezes or coughs, causing the abdomen to suddenly bulge. Therefore, they cannot meet the current needs for renal puncture compression hemostasis structures. Summary of the Invention
[0005] In order to overcome the shortcomings of the prior art, the present invention provides a renal puncture compression hemostasis structure that can adjust the patient's breathing patency and can adapt to the sudden abdominal distension caused by a sudden sneeze or cough, and can adaptively adjust the pressure force.
[0006] The technical solution adopted in this plan is as follows: This plan proposes a renal puncture compression hemostasis structure, including a compression table, fixing bolts, a compression mechanism, a ventilation mechanism, an amplitude measuring mechanism, a pressure control mechanism, and a controller. The fixing bolts pass through both ends of the compression table and are threadedly connected to it, used to fix the compression table to the medical bed. The compression mechanism includes a lowering component on the upper wall of the compression table and an abdominal fitting component at the bottom of the lowering component. The abdominal fitting component is used to fit the patient's abdominal puncture site and apply pressure. The ventilation mechanism includes a positive pressure component on the upper wall of the compression table on both sides of the lowering component, a pushing component inside the positive pressure component, and a delivery component on the side wall of the positive pressure component. The positive pressure component generates positive pressure air, the pushing component pushes the positive pressure air, and the delivery component... The delivery component delivers positive pressure air to the patient's airway to maintain unobstructed breathing. The amplitude measuring mechanism is located on the side wall of the compression table and is used to detect the rise and fall of the patient's abdomen in real time. The pressure control mechanism is located on the side wall of the positive pressure component and is used to adaptively adjust the pressure of the abdominal patch component. The controller is located on the side wall of the positive pressure cylinder of the positive pressure component and is electrically connected to the ventilation mechanism, the amplitude measuring mechanism, and the pressure control mechanism. The detection signal from the amplitude measuring mechanism is transmitted to the controller, which dynamically adjusts the positive pressure of the ventilation mechanism based on the detection signal. When the patient's abdomen suddenly swells, causing the amplitude measuring mechanism to reach a preset detection distance, the controller triggers the pressure control mechanism to reduce the pressure. The positive pressure component simultaneously provides positive pressure air to the ventilation mechanism and provides an air source for the pressure regulation of the pressure control mechanism.
[0007] As a further preferred embodiment of the present invention, the pressing assembly includes a pressing column that penetrates the upper wall of the pressing platform and a guide plate that is disposed on the upper wall of the pressing column; the lining assembly includes an arc-shaped pressure plate disposed on the bottom wall of the pressing column and a lining spring sleeved on the outside of the pressing column, wherein the two ends of the lining spring are respectively connected to the guide plate and the upper wall of the pressing platform, and the initial state is a compressed state.
[0008] In use, the compression table is fixed on the medical bed in the patient's abdominal area, with the abdominal spring in a compressed state. Medical staff pull the lower compression column through the guide plate, and the lower compression column slides along the compression table, causing the arc-shaped compression plate to rise. The patient lies flat on the medical bed, with the arc-shaped compression plate above the patient's puncture site. The medical staff releases the guide plate, and the abdominal spring elastically returns to its original position, causing the lower compression column to slide along the compression table. The lower compression column causes the arc-shaped compression plate to descend and fit against the patient's abdominal puncture site, applying pressure to stop bleeding.
[0009] Preferably, the positive pressure assembly includes positive pressure cylinders symmetrically arranged on the upper walls at both ends of the pressure table, a booster pump arranged on the side wall of the positive pressure cylinder with its boosting end extending through into the inside of the positive pressure cylinder, and a pressure sensor arranged on the upper wall of the positive pressure cylinder with its pressure measuring end extending through into the inside of the positive pressure cylinder.
[0010] The controller is electrically connected to the booster pump and the pressure sensor respectively. The pressure sensor is used to monitor the internal pressure of the positive pressure cylinder in real time and feed it back to the controller.
[0011] Specifically, the pushing component includes an electric push rod disposed on the inner wall of the positive pressure cylinder near the booster pump, a push plate slidably disposed on the inner wall of the positive pressure cylinder away from the booster pump, and a one-way air intake valve penetrating the side wall of the push plate.
[0012] The controller is electrically connected to the electric actuator, which drives the air pusher plate to slide along the inner wall of the positive pressure cylinder, thereby realizing the unidirectional push of positive pressure air.
[0013] During use, to prevent soft tissue collapse of the upper respiratory tract (back of the throat) and resulting in significant fluctuations at the abdominal puncture site while the patient is asleep, a booster pump delivers pressurized air into the positive pressure cylinder. A pressure sensor monitors the internal pressure of the positive pressure cylinder in real time. Initially, the electric actuator is extended, and the pusher plate is located on the inner wall of the positive pressure cylinder at the end furthest from the booster pump. The one-way inlet valve is in contact with the inner wall of the positive pressure cylinder and is closed. The electric actuator shortens, pulling the pusher plate, which slides along the positive pressure cylinder towards the booster pump. The positive pressure air on the side of the pusher plate closest to the booster pump enters the other side of the positive pressure cylinder through the one-way inlet valve. The positive pressure air entering the positive pressure cylinder at the end furthest from the booster pump flows into the telescopic tube through the one-way delivery valve. The electric actuator extends, causing the pusher plate to slide towards the side closest to the one-way delivery valve. The pusher plate causes the one-way inlet valve to contact the inner wall of the positive pressure cylinder, stopping the delivery of positive pressure air into the telescopic tube. The positive pressure ventilation mask is then placed in the sleep position. In the patient's face under these conditions, positive pressure air from inside the telescopic tube flows into the positive pressure ventilation mask. The time for the electric actuator to shorten and extend to deliver positive pressure air is preset. After the electric actuator extends to deliver positive pressure air, the one-way exhaust valve opens, allowing the air exhaled by the sleeping patient to be discharged through the one-way exhaust valve. Simultaneously, the electric actuator shortens, causing the pusher plate to slide along the inner wall of the positive pressure cylinder away from the one-way air supply valve. Positive pressure air passes through the one-way air intake valve and enters the other side of the positive pressure cylinder. After the electric actuator shortens to the set position, the one-way exhaust valve closes, and the electric actuator extends, pushing positive pressure air through the pusher plate into the telescopic tube and the positive pressure ventilation mask. The continuously delivered positive pressure air supports the relaxed tongue base, soft palate, pharyngeal wall, and other soft tissues from inside the respiratory tract, preventing them from collapsing inward and closing, ensuring smooth and stable breathing, reducing or avoiding violent abdominal fluctuations, and providing a relatively calm recovery environment for the healing of the puncture site.
[0014] The delivery assembly includes a one-way air supply valve connected to the side of the positive pressure cylinder away from the booster pump, a telescopic pipe connected to the end of the one-way air supply valve away from the positive pressure cylinder, a positive pressure ventilation mask connected to the side of the telescopic pipe away from the one-way air supply valve, and a one-way exhaust solenoid valve connected to the side wall of the positive pressure ventilation mask; the one-way exhaust solenoid valve is electrically connected to the controller and is used to control the timing of exhaust from the positive pressure ventilation mask.
[0015] Preferably, the amplitude measuring mechanism includes distance measuring sensors symmetrically arranged on both sides of the compression table and a distance measuring block arranged on the upper wall of the arc-shaped pressure plate and located below the distance measuring sensors; the controller is electrically connected to the distance measuring sensors, the distance measuring block moves synchronously with the rise and fall of the patient's abdomen, and the distance measuring sensor detects the distance between itself and the distance measuring block and transmits it to the controller.
[0016] During use, the distance sensor is fixed to the side wall of the compression table and is in a static state. The distance measuring block moves synchronously with the rise and fall of the patient's abdomen, and the distance between the distance measuring block and the distance measuring sensor changes accordingly. The distance measuring sensor detects the distance between itself and the distance measuring block through the distance measuring end, and monitors the rise and fall of the patient's abdomen in real time in order to adjust the air pressure of positive pressure ventilation, thereby better opening the patient's airway and ensuring unobstructed breathing during the patient's sleep.
[0017] Furthermore, the pressure control mechanism includes a control valve connected to the side wall of the positive pressure cylinder, an annular airbag located between the guide plate and the upper wall of the pressure platform and sleeved on the outside of the lower pressure column, a control hose penetrating the guide plate and connecting the annular airbag and the control valve, and a shrink valve penetrating the guide plate and connecting the upper wall of the annular airbag; the controller is electrically connected to the control valve, and the positive pressure air in the positive pressure cylinder inflates the annular airbag through the control hose. After the annular airbag expands, it supports the guide plate to reduce the pressure intensity of the abdominal spring.
[0018] Furthermore, the one-way air intake valve opens when the air pusher plate slides toward the booster pump side, and closes when the air pusher plate slides toward the one-way air delivery valve side and is in contact with the inner wall of the positive pressure cylinder.
[0019] Furthermore, the one-way exhaust valve opens after the electric actuator completes the positive pressure air push and closes before the electric actuator starts the next push.
[0020] When in use, the patient's abdomen will suddenly swell when the patient sneezes or coughs. To avoid excessive pressure on the puncture site by the curved pressure plate, the sudden swelling of the patient's abdomen will cause the measuring block to move. When the distance between the measuring block and the measuring sensor reaches the preset value, the control valve opens, and the positive pressure air near the booster pump of the positive pressure cylinder flows into the annular airbag through the control hose. After the annular airbag is inflated, it generates a supporting force. The annular airbag is supported between the guide plate and the compression table, reducing the pressure intensity of the abdominal spring on the puncture site and ensuring the safety of the puncture site compression operation.
[0021] The beneficial effects achieved by this solution using the above structure are as follows:
[0022] Compared with existing technologies, this solution combines a compression mechanism, a ventilation mechanism, an amplitude measuring mechanism, and a pressure control mechanism. Through the setting of a downward compression component, an abdominal application component, a positive pressure component, a pushing component, and a delivery component, the air pressure of positive pressure ventilation can be dynamically adjusted in real time based on the abdominal fluctuation status detected by the amplitude measuring mechanism. This ensures that the patient's airway is opened and that breathing is unobstructed, thereby reducing the fluctuation amplitude of the abdominal puncture site and allowing the puncture site to heal in a relatively stable environment. This reduces the risk of secondary bleeding at the puncture site and improves the efficiency of the compression structure. At the same time, the annular balloon inflated with high-pressure gas provided by the positive pressure component can form a flexible support for the guide plate, reducing the rebound force caused by the long stretch of the abdominal application spring. This prevents the abdomen from over-inflating when the patient sneezes or coughs, thus avoiding excessive compression of the puncture site and improving the safety of compression of the puncture site.

The fixing bolts 2 are threaded through both ends of the compression platform 1 and are connected to the compression platform 1. The compression mechanism 3 includes a downward pressing component 4 and an abdominal fitting component 7. The downward pressing component 4 is located on the upper wall of the compression platform 1, and the abdominal fitting component 7 is located at the bottom of the downward pressing component 4. The ventilation mechanism 10 includes a positive pressure component 11, a pushing component 15, and a conveying component 19.

The pushing component 15 is located inside the positive pressure component 11. The conveying component 19 is located on the side wall of the positive pressure component 11. The amplitude measuring mechanism 24 is located on the side wall of the compression platform 1, and the pressure control mechanism 27 is located on the side wall of the positive pressure component 11.
[0041] The pressing assembly 4 includes a pressing column 5 and a guide plate 6. The pressing column 5 is disposed through the upper wall of the pressing platform 1, and the guide plate 6 is disposed on the upper wall of the pressing column 5. The abdominal fitting assembly 7 includes an arc-shaped pressing plate 8 and an abdominal fitting spring 9. The arc-shaped pressing plate 8 is disposed on the bottom wall of the pressing column 5, and the abdominal fitting spring 9 is disposed between the guide plate 6 on the outside of the pressing column 5 and the upper wall of the pressing platform 1.
[0042] The positive pressure assembly 11 includes a positive pressure cylinder 12, a booster pump 13, and a pressure sensor 14. The positive pressure cylinder 12 is symmetrically arranged on the upper walls of both ends of the pressure table 1. The booster pump 13 is located on the side wall of the positive pressure cylinder 12, with its boosting end penetrating inside the positive pressure cylinder 12. The pressure sensor 14 is located on the upper wall of the positive pressure cylinder 12, with its pressure measuring end penetrating inside the positive pressure cylinder 12. The pushing assembly 15 includes an electric push rod 16, a push plate 17, and a one-way air intake valve 18. The electric push rod 16 is located on the inner wall of the positive pressure cylinder 12 near the booster pump 13. The push plate 17 is slidably disposed on the positive pressure cylinder 12 away from the booster pump. The inner wall of one end of 13 has an electric actuator 16 connected to the push plate 17 at its power end. The one-way air intake valve 18 is installed through the side wall of the push plate 17. The conveying assembly 19 includes a one-way air supply valve 20, a telescopic pipe 21, a positive pressure ventilation mask 22, and a one-way exhaust valve 23. The one-way air supply valve 20 is connected to the side of the positive pressure cylinder 12 away from the booster pump 13. The telescopic pipe 21 is connected to the end of the one-way air supply valve 20 away from the positive pressure cylinder 12. The positive pressure ventilation mask 22 is connected to the side of the telescopic pipe 21 away from the one-way air supply valve 20. The one-way exhaust valve 23 is connected to the side wall of the positive pressure ventilation mask 22.
[0043] The amplitude measuring mechanism 24 includes a distance measuring sensor 25 and a distance measuring block 26. The distance measuring sensor 25 is symmetrically arranged on both sides of the pressure table 1, and the distance measuring block 26 is arranged on the upper wall of the arc-shaped pressure plate 8 below the distance measuring sensor 25.
[0044] The pressure control mechanism 27 includes a pressure control solenoid valve 28, a ring-shaped air bladder 29, a pressure control hose 30, and a compression valve 31. The pressure control solenoid valve 28 is connected to the side wall of the positive pressure cylinder 12. The ring-shaped air bladder 29 is located between the guide plate 6 on the outside of the lower pressure column 5 and the upper wall of the pressure table 1. The pressure control hose 30 passes through the guide plate 6 and is connected between the ring-shaped air bladder 29 and the pressure control solenoid valve 28. The compression valve 31 passes through the guide plate 6 and is connected to the upper wall of the ring-shaped air bladder 29.
[0045] The positive pressure cylinder 12 is equipped with a controller 32 on its side wall.
[0046] The controller 32 is electrically connected to the booster pump 13, pressure sensor 14, electric actuator 16, one-way exhaust valve 23, distance sensor 25 and control valve 28 respectively.
[0047] In practical use, the fixing bolt 2 is unscrewed out of the compression table 1, the openings on both sides of the compression table 1 are opened and clamped on the guardrail of the medical bed, and the fixing bolt 2 is screwed into the compression table 1 to close its opening, so that the compression table 1 is fixed on the medical bed in the patient's abdominal area.
[0048] In the initial state, the electric actuator 16 is in the extended state, the air pusher 17 is located on the inner wall of the positive pressure cylinder 12 away from the booster pump 13, the one-way air inlet valve 18 is in contact with the inner wall of the positive pressure cylinder 12 and is in a blocked state, and the abdominal spring 9 is in a compressed state. The medical staff pulls the lower pressure column 5 through the guide plate 6. The lower pressure column 5 slides along the compression table 1 and drives the arc-shaped pressure plate 8 to rise. The patient lies flat on the medical bed, and the arc-shaped pressure plate 8 is located above the patient's puncture site. The medical staff releases the guide plate 6, and the abdominal spring 9 elastically resets and drives the lower pressure column 5 to slide along the compression table 1. The lower pressure column 5 drives the arc-shaped pressure plate 8 to descend and contact the patient's abdominal puncture site to compress and stop bleeding.
[0049] To prevent the soft tissue of the upper respiratory tract (back of the throat) from collapsing and causing large fluctuations at the abdominal puncture site while the patient is sleeping, a positive pressure ventilation mask 22 is placed on the patient's face. The controller 32 controls the start of the booster pump 13, which delivers pressurized air into the positive pressure cylinder 12. The pressure sensor 14 monitors the pressure inside the positive pressure cylinder 12 through a detection probe.
[0050] During positive pressure ventilation, the controller 32 controls the reciprocating motion of the power end of the electric actuator 16. The power end of the electric actuator 16 shortens, pulling the air pusher plate 17. The air pusher plate 17 slides along the positive pressure cylinder 12 towards one end of the booster pump 13. The positive pressure air on the side of the air pusher plate 17 closest to the booster pump 13 enters the other side of the positive pressure cylinder 12 through the one-way air inlet valve 18. The power end of the electric actuator 16 extends, causing the air pusher plate 17 to slide towards the side closest to the one-way air delivery valve 20, entering the positive pressure cylinder 12 away from the booster pump 13. The positive pressure air, squeezed by the push plate 17, flows into the telescopic tube 21 through the one-way air supply valve 20. The push plate 17 drives the one-way air intake valve 18 to fit against the inner wall of the positive pressure cylinder 12, stopping the push of positive pressure air into the telescopic tube 21. The positive pressure air inside the telescopic tube 21 flows into the positive pressure ventilation mask 22, pushing the positive pressure air inside the positive pressure ventilation mask 22 into the patient's airway, opening up the upper airway that is prone to collapse during the patient's sleep, thereby ensuring smooth and stable breathing.
[0051] The time for the electric push rod 16 to shorten and extend is preset. After the electric push rod 16 extends and pushes positive pressure air, the controller 32 controls the one-way exhaust valve 23 to open. The air exhaled by the sleeping patient is discharged through the one-way exhaust valve 23. At the same time, the electric push rod 16 shortens and drives the push plate 17 to slide away from the one-way air supply valve 20 along the inner wall of the positive pressure cylinder 12. The positive pressure air passes through the one-way air intake valve 18 and enters the other side of the positive pressure cylinder 12. After the electric push rod 16 shortens to the set position, the one-way exhaust valve 23 closes. The electric push rod 16 extends and pushes the positive pressure air into the telescopic tube 21 and the positive pressure ventilation mask 22 through the push plate 17. The continuously delivered positive pressure air supports the relaxed tongue base, soft palate, pharyngeal wall and other soft tissues from inside the respiratory tract, preventing them from collapsing and closing inward, ensuring smooth and stable breathing, reducing or avoiding violent abdominal fluctuations caused by this, and providing a relatively calm rehabilitation environment for the healing of the puncture site.
[0052] The distance sensor 25 is fixed to the side wall of the compression table 1 in a static state. The distance measuring block 26 changes the distance between itself and the distance sensor 25 as the patient's abdomen rises and falls. The distance sensor 25 detects the distance between itself and the distance measuring block 26 through the measuring end, and monitors the rise and fall of the patient's abdomen in real time. When the amplitude of the rise and fall of the patient's abdomen increases, the air pressure delivered to the positive pressure cylinder 12 by the booster pump 13 is increased, thereby better opening the patient's airway and ensuring that the patient's breathing is unobstructed during sleep.
[0053] When the patient sneezes or coughs, their abdomen suddenly swells. To avoid excessive pressure on the puncture site by the arc-shaped pressure plate 8, the control valve 28 opens when the distance between the measuring block 26 and the measuring sensor 25 reaches a preset distance through the arc-shaped pressure plate 8. Positive pressure air from the positive pressure cylinder 12 near the booster pump 13 flows into the annular bladder 29 through the control hose 30. After the annular bladder 29 inflates, it generates support force. The annular bladder 29 is supported between the guide plate 6 and the compression table 1, reducing the pressure of the abdominal spring 9 on the puncture site and ensuring the safety of the puncture site compression operation. When the patient exhales, the abdominal spring 9 returns to its original position and squeezes the annular bladder 29. The gas inside the annular bladder 29 is discharged through the compression valve 31, and the distance between the measuring block 26 and the measuring sensor 25 enters the preset range. The control valve 28 then closes. The above operation can be repeated for the next use.
