Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and particularly relates to a constant-pressure controllable enema reduction package for infantile intussusception and an enema reduction method. Background Art

[0002] Intussusception is a common acute abdomen in pediatric surgery. The current treatment options include surgical treatment and non-surgical treatment. Among them, non-surgical treatment is further divided into two methods: air enema reduction and liquid enema reduction. Their principles are similar, that is, air or liquid is injected into the intestine, and the pressure generated by the air or liquid is used to gradually withdraw the intussuscepted intestine, restore the normal structure and patency of the intestine, so as to achieve the purpose of treating intussusception. At present, the success rate of liquid enema reduction is relatively high, and the operation is relatively simple with less trauma. In actual use, traditional enema devices rely on manual injection of liquid (such as a syringe). The operation method has a strong technical dependence. The judgment of the enema liquid pressure highly depends on the doctor's experience. Novice operation is likely to lead to reduction failure or complications. Excessive pressure may cause intestinal perforation, and insufficient pressure cannot effectively reduce. Most medical staff need to judge whether the pressure is too high according to the patient's reaction and imaging performance. Once the pressure is too high, the pressure needs to be manually released. During the process of manually releasing the pressure, the operation process is unstable and the pressure relief rate is not easy to control.

[0003] Especially for infants and young children with weak intestinal walls, too fast pressure relief may cause the intussuscepted intestine to lose support instantly, and the already partially reduced intestinal segment may retract again due to the sudden drop in pressure, requiring repeated operations or even turning to surgical treatment. Summary of the Invention

[0004] The purpose of the present invention is to provide a constant-pressure controllable enema reduction package for infantile intussusception and an enema reduction method, so as to solve the technical problem that in the prior art, judging whether the pressure is too high according to the patient's reaction and imaging performance results in instability in the operation process and difficulty in controlling the pressure relief rate.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solutions: A constant-pressure controllable enema reduction package for infantile intussusception includes: A housing, and a three-way pipe arranged inside the housing. The three-way pipe is respectively connected with a liquid inlet pipe, a pressure relief pipe and a liquid outlet conduit. The liquid inlet pipe and the liquid outlet conduit pass through the housing, and the pressure relief pipe is inside the housing; A pressure sensor is installed inside the liquid outlet conduit near the tee, and the pressure sensor is used to monitor the enema pressure inside the liquid outlet conduit. The pressure sensor is connected to a controller. The pressure relief pipeline is connected to a pressure control pipeline, and a pressure regulator connected to the controller is installed inside the pressure control pipeline. The controller regulates the pressure regulator based on the monitoring result of the pressure sensor to keep the enema pressure inside the liquid outlet conduit stable; The controller is used to regulate the pressure regulator to move along the pressure control pipeline to adjust the accommodation volume of the pressure control pipeline and the enema pressure of the liquid outlet conduit.

[0006] As a preferred solution of the present invention, a spherical cavity is provided at the intersection of the pipe orifices of the tee. Three through holes are respectively arranged on the side curved surface of the spherical cavity in the same horizontal plane, and the three through holes are respectively connected to a liquid inlet pipeline, a pressure relief pipeline and a liquid outlet conduit; The pressure control pipeline is vertically connected to the pressure relief pipeline, and the pressure relief pipeline is used to relatively increase or decrease the total accommodation volume of the pressure control pipeline.

[0007] As a preferred solution of the present invention, the pressure regulator includes an annular panel, and a double-headed valve stem movably installed at the center position of the annular panel. A return spring is provided between the valve heads at both ends of the double-headed valve stem and the annular panel, and electromagnetic components are provided at both ends of the double-headed valve stem in the pressure control pipeline; After the electromagnetic component far from the pressure control pipeline is energized, a force is generated between the double-headed valve stem far from the pressure control pipeline to regulate the double-headed valve stem to move away from the pressure control pipeline to increase the surrounding volume of the tee and reduce the hydraulic pressure inside the tee to keep the enema reset pressure stable; After the electromagnetic component close to the pressure control pipeline is energized, a force is generated between the double-headed valve stem close to the pressure control pipeline to regulate the double-headed valve stem to move close to the pressure control pipeline to reduce the surrounding volume of the tee and increase the hydraulic pressure inside the tee to keep the enema reset pressure stable.

[0008] As a preferred solution of the present invention, an emergency brake valve is installed inside the spherical cavity of the tee. The emergency brake valve includes a hollow ball arranged on the inner wall of the spherical cavity and capable of rotating along the inner wall of the spherical cavity; First openings corresponding to the three through holes of the tee one by one are provided on the spherical side curved surface of the hollow ball, and the first openings are on the same horizontal plane. A second opening is provided directly above the plane where the first openings are located on the hollow ball.

[0009] As a preferred embodiment of the present invention, the included angle between the second opening and the first opening is 90°. After the hollow ball rotates counterclockwise by 90°, the spherical wall of the hollow ball blocks the through hole connecting the three-way pipe and the liquid outlet conduit. After the hollow ball rotates clockwise by 90° again, the first opening of the hollow ball corresponds to the three through holes of the three-way pipe one by one.

[0010] As a preferred embodiment of the present invention, a connecting rod is fixedly installed at a position of the hollow ball away from the pressure relief pipe and relative to the pressure relief pipe. The connecting rod passes through the outer shell, and a knob is installed at the outer end of the connecting rod.

[0011] As a preferred embodiment of the present invention, a balloon is provided on the liquid inlet pipe, and the flow rate of the enema fluid is controlled by squeezing the balloon.

[0012] In addition, the present invention also provides an enema reduction method for a pressure-stabilizing and controllable pediatric intussusception enema reduction kit, including the following steps: Rotate the emergency brake valve to the open state, and input enema liquid into the three-way pipe through the liquid inlet pipe; Monitor the hydraulic pressure in the three-way pipe in real time, and when the hydraulic pressure exceeds the set threshold, automatically adjust the pipe volume of the pressure control pipe connected to the three-way pipe until the hydraulic pressure in the three-way pipe reaches the set threshold; After adjusting the pipe volume of the pressure control pipe connected to the three-way pipe, when the hydraulic pressure in the three-way pipe still cannot drop to the set threshold, rotate the emergency brake valve to the closed state to block the liquid outlet conduit of the three-way pipe.

[0013] As a preferred embodiment of the present invention, when the hydraulic pressure is greater than the set threshold, adjust the pipe volume of the pressure control pipe connected to the three-way pipe to increase, so that the overall volume surrounded by the three-way pipe becomes larger, and the enema liquid in the three-way pipe is transferred to the pressure control pipe to reduce the hydraulic pressure in the three-way pipe and make the hydraulic pressure in the three-way pipe reach the set threshold; When the hydraulic pressure is less than the set threshold, adjust the pipe volume of the pressure control pipe connected to the three-way pipe to decrease, so that the overall volume surrounded by the three-way pipe becomes smaller, and the enema liquid in the pressure control pipe is transferred into the three-way pipe to increase the hydraulic pressure in the three-way pipe and make the hydraulic pressure in the three-way pipe reach the set threshold.

[0014] As a preferred embodiment of the present invention, after the emergency brake valve rotates counterclockwise by 90°, the spherical wall of the emergency brake valve blocks the through hole connecting the three-way pipe and the liquid outlet conduit. After the emergency brake valve is rotated clockwise by 90° and reset, the three first openings of the emergency brake valve respectively correspond to the three through holes of the three-way pipe, so that the enema liquid in the three-way pipe can be transferred to the liquid outlet conduit again.

[0015] The present invention has the following beneficial effects compared with the prior art: The present invention uses a pressure sensor to monitor the enema pressure in real time and feeds it back to the pressure regulator in time through a controller, realizing full-automatic and precise regulation of the enema pressure, greatly reducing the risk of intestinal injury caused by excessive pressure, significantly improving the treatment safety. In terms of pressure regulation, under the transmission of the electrical signal of the controller, the pressure regulator moves stably back and forth along the pressure relief pipeline, and the pressure attenuation and increase processes are smoother, reducing the irritation to the intestine, reducing the risk, maintaining a constant-pressure enema reduction operation, and an emergency brake valve is added, which can urgently close the liquid outlet conduit when the pressure regulator fails to achieve the pressure relief function, reducing the liquid pressure in the liquid outlet conduit.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1 and Figure 2 shown, the present invention provides a voltage-stabilized and controllable enema reduction package for pediatric intussusception, which includes a housing 1 and a three-way pipe 2 arranged inside the housing 1. The three-way pipe 2 is respectively connected with a liquid inlet pipe 3, a pressure relief pipe 4 and a liquid outlet catheter 5. The liquid inlet pipe 3 and the liquid outlet catheter 5 pass through the housing 1, and the pressure relief pipe 4 is inside the housing 1. Among them, a balloon 12 is provided on the liquid inlet pipe 3, and the flow rate of the enema fluid is controlled by squeezing the balloon 12.

[0020] A pressure sensor 6 is installed inside the liquid outlet catheter 5 near the three-way pipe 2. The pressure sensor 6 is used to monitor the enema pressure in the liquid outlet catheter 5, and the pressure sensor 6 is connected with a controller 7. The pressure relief pipe 4 is connected with a pressure control pipe 8, and a pressure regulator 9 connected with the controller 7 is installed in the pressure control pipe 8. The controller 7 regulates the pressure regulator 9 based on the monitoring result of the pressure sensor 6 so that the enema pressure in the liquid outlet catheter 5 remains stable.

[0021] The controller 7 is used to regulate the pressure regulator 9 to move along the pressure control pipe 8 to adjust the accommodation volume of the pressure control pipe 8 and the enema pressure of the liquid outlet catheter 5.

[0022] Place one end of the liquid inlet pipe 3 in the enema liquid, press the balloon 12 to inject the liquid to make the balloon 12 full, and then regularly press the balloon 12 once to slowly inject the liquid in the balloon 12 into the three-way pipe 2. By controlling the pressure of pressing the balloon 12 once, the stable control of the enema process is realized, and the liquid pressure in the three-way pipe 2 and the liquid outlet catheter 5 is prevented from fluctuating too much and accidentally touching the pressure sensor 6.

[0023] When actually using the enema reduction package provided by this embodiment, the enema fluid is transported to the three-way pipe 2 through the liquid inlet pipe 3, and is split by the three-way pipe 2 and flows to the pressure relief pipe 4, the liquid outlet catheter 5 and the pressure relief pipe 4 respectively. The pressure sensor 6 real-time monitors the liquid pressure level in the liquid outlet catheter 5. The data collected by the pressure sensor 6 is converted into an electrical signal and transmitted to the controller 7. The controller 7 and the pressure regulator 9 are electrically connected, and the controller 7 regulates the position of the pressure regulator 9 based on the monitoring result of the pressure sensor 6.

[0024] For some doctors with insufficient experience, they are not proficient in using the balloon 12 and lack experience, which is very likely to cause the pressure in the liquid outlet conduit 5 to be too high or too low. Among them, when the pressure in the liquid outlet conduit 5 is too high, the controller 7 of this embodiment will drive the pressure regulator 9 to slide outward along the pressure control pipeline 8. At this time, the cavity in the pressure control pipeline 8 forms a negative pressure, so as to slowly suck part of the liquid in the three-way pipe 1 into the pressure control pipeline 8. The liquid volume in the three-way pipe 1 and the liquid outlet conduit 5 decreases, so as to achieve pressure relief. Maintaining stable pressure helps to avoid excessive intestinal dilation and reduce the stimulation of intestinal wall nerves and muscles.

[0025] When the pressure in the liquid outlet conduit 5 is too low, in order to accelerate the enema reduction speed in this embodiment, the controller 7 will drive the pressure regulator 9 to slide along the pressure control pipeline 8 towards the pressure relief pipeline 4. At this time, the volume of the cavity in the pressure control pipeline 8 decreases, so as to slowly squeeze the liquid in the pressure control pipeline 8, the pressure relief pipeline 4 and the three-way pipe 1 to move to the liquid outlet conduit 5. The liquid volume in the liquid outlet conduit 5 increases, so as to achieve pressure increase. Maintaining stable pressure helps to avoid too long enema reduction time.

[0026] Therefore, this embodiment realizes the pressure relief and pressure increase regulation of the liquid outlet conduit 5 by regulating the cavity volume of the pressure control pipeline 8, ensures that the liquid pressure in the liquid outlet conduit 5 is always maintained within a stable range, avoids excessive intestinal dilation, reduces the stimulation of intestinal wall nerves and muscles, and improves the operation efficiency at the same time.

[0027] Furthermore, during the pressure relief process, the controller 7 further controls the moving speed of the pressure regulator 9. The controller 7 sets threshold nodes. When the pressure exceeds the first node, the moving speed of the pressure regulator 9 is controlled to be slow, and at this time the pressure relief rate is slow. When the pressure exceeds the second node, the moving speed of the pressure regulator 9 is controlled to be fast, and at this time the pressure relief rate is fast. Among them, the pressure value of the first node is less than the pressure value of the second node.

[0028] It should be noted that the movement of the pressure regulator 9 is a uniform movement in any state, ensuring that the liquid in the liquid outlet conduit 5 decays uniformly and the pressure drops stably, avoiding intestinal damage caused by sudden pressure drop during enema.

[0029] As Figure 3 shown, a spherical cavity is provided at the intersection position of the pipe orifices of the three-way pipe 2. Three through holes 13 are respectively arranged on the side curved surface of the spherical cavity in the same horizontal plane. The three through holes 13 are respectively connected with a liquid inlet pipeline 3, a pressure relief pipeline 4 and a liquid outlet conduit 5.

[0030] The pressure control pipeline 8 is vertically connected to the pressure relief pipeline 4, and the pressure relief pipeline 4 is used to relatively increase or decrease the total accommodation volume of the pressure control pipeline 8.

[0031] The spherical cavity of the three-way pipe 2 can be used as a container for temporarily storing enema liquid. The enema liquid introduced into the three-way pipe 2 from the liquid inlet pipe 3 enters the spherical cavity, the pressure relief pipe 4, and the liquid outlet conduit 5 respectively. Among them, the cavity volumes in the spherical cavity, the pressure relief pipe 4, and the pressure control pipe 8 are used as the overall cavity volume of the three-way pipe 2.

[0032] When adjusting the pressure regulator 9 to increase the cavity volume in the pressure control pipe 8 to increase the overall cavity volume of the three-way pipe 2, the liquid pressure in the liquid outlet conduit 5 decreases. When adjusting the pressure regulator 9 to decrease the cavity volume in the pressure control pipe 8 to decrease the overall cavity volume of the three-way pipe 2, the liquid pressure in the liquid outlet conduit 5 increases.

[0033] It should be particularly noted that the advantage of this embodiment compared with directly installing a solenoid valve on the liquid outlet conduit 5 is that: if a solenoid valve is installed on the liquid outlet conduit 5, there are only two situations of opening or closing the solenoid valve, and the flow aperture of the liquid outlet conduit 5 cannot be adjusted. And even if the flow aperture of the liquid outlet conduit 5 can be adjusted, especially when reducing the flow aperture, the liquid outlet speed of the corresponding liquid outlet conduit 5 increases, which will stimulate the intestinal wall nerves and muscles of the patient. Especially for patients with relatively thin intestinal walls, it is very easy to cause the problem of intestinal perforation due to the liquid impact pressure.

[0034] In this embodiment, the pressure control pipe 8 is connected to the side of the pressure relief pipe 4. By increasing or decreasing the cavity volume in the pressure control pipe 8, the overall cavity volume of the three-way pipe 2 is increased and the overall cavity volume of the three-way pipe 2 is decreased. At this time, the influence on the flow rate of the enema liquid in the liquid outlet conduit 5 is small, and the flow aperture of the liquid outlet conduit 5 remains unchanged all the time. Therefore, the stimulation to the intestinal wall nerves and muscles is reduced.

[0035] Furthermore, in order to realize the pressurization and pressure relief of the liquid outlet conduit 5, as Figure 4 shown, the pressure regulator 9 includes an annular panel 91 and a double-headed valve stem 92 movably installed at the central position of the annular panel 91. A return spring 93 is provided between the two end valve heads of the double-headed valve stem 92 and the annular panel 91, and electromagnetic components 94 are provided at both ends of the double-headed valve stem 92 for the pressure control pipe 8.

[0036] After the electromagnetic component 94 away from the pressure control pipe 8 is energized, a force is generated between the double-headed valve stem 92 and the electromagnetic component 94 away from the pressure control pipe 8 to adjust the double-headed valve stem 92 away from the pressure control pipe 8, so as to increase the surrounding volume of the three-way pipe 2 and reduce the hydraulic pressure in the three-way pipe 2, so as to make the enema reset pressure stable.

[0037] After the electromagnetic component 94 near the pressure control pipe 8 is powered on, a force is generated between it and the double-headed valve stem 92 near the pressure control pipe 8 to regulate the double-headed valve stem 92 to approach the pressure control pipe 8, so as to reduce the enclosed volume of the three-way pipe 2 and increase the hydraulic pressure in the three-way pipe 2, so as to stabilize the enema reset pressure.

[0038] Suppose the double-headed valve stem 92 far from the pressure control pipe 8 is the first valve head, and the double-headed valve stem 92 near the pressure control pipe 8 is the second valve head. When the electromagnetic component 94 far from the pressure control pipe 8 is correspondingly connected, the electromagnetic component 94 generates a force on the first valve head to drive the first valve head and the second valve head away from the pressure control pipe 8, so as to increase the cavity volume of the pressure control pipe 8 and further increase the enclosed volume of the entire three-way pipe 2.

[0039] When the electromagnetic component 94 far from the pressure control pipe 8 is powered off, the electromagnetic component 94 no longer generates a force on the first valve head, and the first valve head and the second valve head automatically reset under the driving action of the return spring 93.

[0040] When the electromagnetic component 94 near the pressure control pipe 8 is correspondingly connected, the electromagnetic component 94 generates a force on the second valve head to drive the first valve head and the second valve head close to the pressure control pipe 8, so as to reduce the cavity volume of the pressure control pipe 8 and further reduce the enclosed volume of the entire three-way pipe 2.

[0041] When the electromagnetic component 94 near the pressure control pipe 8 is powered off, the electromagnetic component 94 no longer generates a force on the second valve head, and the first valve head and the second valve head automatically reset under the driving action of the return spring 93.

[0042] An independent battery can be installed inside the controller 7. The controller 7 inputs power and signals to the pressure regulator 9 through a data cable. By adjusting the power-on situation of the electromagnetic component 94, the position of the double-headed valve stem 92 can be dynamically controlled. Among them, a magnetic block is installed on the double-headed valve stem 92. When the conductive current of the electromagnetic component 94 is relatively large, the magnetic force generated by the electromagnetic component 94 is stronger, and the moving amplitude of the double-headed valve stem 92 is faster, and the pressure relief rate is faster. Otherwise, the pressure relief rate decreases.

[0043] It should be noted that for infants and young children with a small age, the threshold value of the controller 7 is lowered. By reducing the trigger threshold, the system responds earlier to small pressure deviations. The pressure regulator 9 starts when it touches a smaller pressure fluctuation, and at the same time reduces the current intensity, slows down the moving amplitude of the valve stem, avoids too fast pressure changes in the liquid outlet conduit 5, adjusts the pressure parameters, and ensures operation safety.

[0044] As Figure 3 shown, an emergency brake valve is installed in the spherical cavity of the three-way pipe 2. The emergency brake valve includes a hollow ball 11 arranged on the inner wall of the spherical cavity and capable of rotating along the inner wall of the spherical cavity.

[0045] The hollow ball 11 has a first opening 14 on its spherical side surface, which corresponds to the three through holes 13 of the tee pipe 2 one by one. The first openings 14 are on the same horizontal plane, and the hollow ball 11 has a second opening 15 just above the plane where the first openings 14 are located.

[0046] The angle between the second opening 15 and the first opening 14 is 90°. After the hollow ball 11 rotates 90° counterclockwise, the ball wall of the hollow ball 11 blocks the through hole 13 connecting the three-way pipe 2 and the liquid outlet conduit 5 .

[0047] After the hollow ball 11 is rotated 90° clockwise again, the first openings 14 of the hollow ball 11 correspond to the three through holes 13 of the three-way pipe 2 one by one.

[0048] The hollow ball 11 is away from the pressure relief pipe 4 and a connecting rod is fixedly installed at a relative position to the pressure relief pipe 4. The connecting rod passes through the housing 1, and a knob 10 is installed at the outer end of the connecting rod.

[0049] During the injection process of the balloon 12, the additional emergency brake valve can further correct the amount of liquid injected into the liquid inlet catheter 5. Since the pressure regulator 9 has a limited range for increasing the cavity volume of the pressure control pipeline 8, when the pressure regulator 9 is continued to be used to increase the cavity volume of the pressure control pipeline 8 to the maximum and the problem of excessive pressure still occurs, it means that the enema liquid injection speed of the current balloon 12 is too fast. The emergency brake valve is used for emergency stopping of the liquid inlet catheter 5. By rotating the knob 10 counterclockwise, the opening originally aligned with the liquid outlet catheter 5 is rotated to the top. At this time, the inlet of the liquid outlet catheter 5 is immediately closed, and the input of the enema liquid is forced to stop.

[0050] After the enema liquid in the liquid outlet conduit 5 flows naturally into the intestine, the knob 10 is rotated clockwise again to reset the original opening of the liquid outlet conduit 5. At this time, the inlet of the liquid outlet conduit 5 is opened, and the next step of enema liquid input can be carried out.

[0051] like Figure 5 As shown, the enema resetting method of the above-mentioned voltage-controlled enema resetting bag for pediatric intussusception comprises the following steps: Turn the emergency brake valve to the open state, and input the enema liquid into the three-way pipe through the liquid inlet pipe; Monitor the hydraulic pressure in the tee pipe in real time, and when the hydraulic pressure exceeds the set threshold, automatically adjust the pipe volume of the pressure control pipe connected to the tee pipe until the hydraulic pressure in the tee pipe reaches the set threshold; When the hydraulic pressure is greater than the set threshold, the volume of the pressure-controlling pipeline connected to the tee is increased, so that the volume surrounded by the tee as a whole becomes larger, and the enema liquid in the tee is transferred to the pressure-controlling pipeline to reduce the hydraulic pressure in the tee, so that the hydraulic pressure in the tee reaches the set threshold; When the hydraulic pressure is less than the set threshold value, the pipe volume of the pressure control pipe connected to the three-way pipe is adjusted to decrease, so that the volume surrounded by the overall three-way pipe becomes smaller, and the enema liquid in the pressure control pipe is transferred into the three-way pipe to increase the hydraulic pressure in the three-way pipe, so that the hydraulic pressure in the three-way pipe reaches the set threshold value.

[0052] When the hydraulic pressure in the three-way pipe still cannot drop to the set threshold value after adjusting the pipe volume of the pressure control pipe connected to the three-way pipe, the emergency brake valve is rotated to the closed state to block the liquid outlet conduit of the three-way pipe.

[0053] After the emergency brake valve rotates counterclockwise by 90°, the spherical wall of the emergency brake valve blocks the through hole connecting the three-way pipe and the liquid outlet conduit; After the emergency brake valve rotates clockwise by 90° to reset, the three first openings of the emergency brake valve respectively correspond to the three through holes of the three-way pipe, so that the enema liquid in the three-way pipe can be transferred to the liquid outlet conduit again.

[0054] In this embodiment, a pressure sensor is used to monitor the enema pressure in real time and is timely fed back to the pressure regulator through the controller, so as to realize the full-automatic and precise regulation of the enema pressure, greatly reduce the risk of intestinal injury caused by excessive pressure, and significantly improve the treatment safety. In terms of pressure regulation, under the transmission of the electrical signal of the controller, the pressure regulator moves reciprocally stably along the pressure relief pipe, and the pressure attenuation process is smoother, reducing the irritation to the intestine and lowering the risk. In addition, an emergency brake valve is added, which can emergently close the liquid outlet conduit when the pressure regulator fails to achieve the pressure relief function, reducing the liquid pressure in the liquid outlet conduit.

The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
