Description

Technical Field

[0001] The utility model relates to the field of medical technology, and particularly to a reduction system for intussusception of children by enema. Background Art

[0002] Enema technology injects liquid or gas into the intestine, and uses the pressure to reduce the intussuscepted intestinal segment. This method has lower trauma and faster recovery time compared with surgical operation, so it has been gradually widely used in the treatment of intussusception of children. The early enema reduction system may be relatively simple, only including an enema tube and an injection device, and the operation process mainly depends on the doctor's experience and feeling. However, the reduction effect of this method may not be stable enough and there is a certain degree of operation difficulty. With the progress of medical imaging technology, imaging technologies such as X-ray and ultrasound have been gradually introduced into the enema reduction system. These imaging technologies can help doctors more accurately observe the situation of intussusception and the reduction process, so as to improve the success rate and safety of reduction. In recent years, with the continuous innovation of medical equipment and the development of intelligent technology, the enema reduction system for intussusception of children has been further upgraded. Modern enema reduction systems may combine functions such as intelligent pressure control, automatic liquid injection, navigation and positioning, making the operation more convenient, accurate and safe.

[0003] In an intussusception reduction device and its use method with the patent number CN201510226496.9, when using this intussusception reduction device for enema, some normal saline overflows from the anus of the child. These overflow liquids are collected in an overflow liquid collector and then the weight of the overflowed liquid is obtained by weighing. Then, the same weight of liquid is re-injected into the patient's intestine to maintain the pressure inside the intestine. First of all, this kind of overflow will cause the pressure inside the intestine to decrease, making it difficult to form stable pressure control. By enhancing the pressure through subsequent supplementation, the response speed is slow and the pressure is unstable. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a reduction system for intussusception of children by enema, which has the advantages of preventing the input liquid from overflowing and ensuring the stability of the internal pressure, and solves the problems that some normal saline overflows from the anus of the child, and this kind of overflow will cause the pressure inside the intestine to decrease, making it difficult to form stable pressure control.

[0006] (II) Technical Solutions

[0007] To achieve the above object of preventing the input liquid from flowing out and ensuring the stability of the internal pressure, the present utility model provides the following technical solutions: A pediatric intussusception enema reduction system includes an ultrasonic device, an operation table, and a colon air injector. The ultrasonic device and the colon air injector are respectively arranged on two side edges of the operation table. The colon air injector is respectively provided with a water injection hose and an air injection hose. The end of the water injection hose is provided with an anal tube, and an airbag is arranged in the middle of the anal tube. An intestinal pressure sensor is arranged at one end of the anal tube extending into the intestine. The other end of the air injection hose is communicated with the airbag. An external pressure sensor is arranged at the near-airbag end of the hose, and a valve is arranged at the far-airbag end of the hose. A control center is arranged on the colon air injector.

[0008] Preferably, the intestinal pressure sensor and the external pressure sensor are connected to the control center for data communication.

[0009] Preferably, an internal spring is arranged inside the airbag, and the installation direction of the internal spring is the same as the direction of the anal tube.

[0010] Preferably, the elastic force of the internal spring is greater than the expansion force generated when the airbag expands.

[0011] Preferably, the valve is a manual valve.

[0012] Preferably, the valve is an electronic valve, and the valve is connected to the control center for data communication.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides a pediatric intussusception enema reduction system, which has the following beneficial effects:

[0015] This pediatric intussusception enema reduction system is used by the coordinated operation of a control center, a colon air injector, and an airbag. When in use, the patient lies on their side or flat on the operating table. The ultrasonic device is used to detect the intussusception situation in the patient's intestine. After the examination, the data is collected by the control center. At this time, the anal tube is inserted 10 cm - 20 cm into the patient's anus. The colon air injector is started to inflate the airbag first, causing the airbag to bulge and block the intestine to prevent liquid overflow during subsequent liquid injection. Since there is an internal spring in the airbag that is in the opposite direction to the anal tube, when inflating the airbag, without the tension of the internal spring on the airbag, the airbag will expand in all directions. At this time, the pressure at the contact area between the airbag and the intestinal wall is not concentrated enough, and the pressure formed inside the airbag is also not concentrated enough, easily causing liquid overflow. After having the tension of the internal spring, it will limit the deformation state of the airbag, so that it does not expand in the left and right directions during expansion, but expands in the up and down directions. At this time, the airbag will be expanded into a disc shape, and the side of the disc-shaped airbag will tightly press against the inner wall of the intestine. The pressure generated inside the airbag will also be concentrated and applied to the contact area with the intestinal wall, thus preventing liquid overflow. When the airbag is inflated to a certain extent, the valve is closed, and the pressure inside the airbag is recorded by the external pressure sensor and transmitted to the control center, and the pressure of the airbag on the intestinal wall is calculated. Then, liquid is injected into the patient's body through the colon air injector and the water injection hose. After injecting for a certain period of time, a certain pressure will be generated in the patient's intestine. The value of this pressure is recorded by the intestinal pressure sensor and transmitted to the control center. When the pressure inside the intestine continues to increase and the pressure inside the intestine is about to be greater than the pressure generated by the airbag on the intestinal wall, it indicates that if liquid is injected at this time, liquid overflow may occur. At this time, the valve is opened, and the control center controls the colon air injector to inflate the airbag again, increasing the pressure of the airbag on the intestinal wall and always making it greater than the pressure inside the intestine, so that the liquid cannot overflow, ensuring that the pressure inside the intestine is stably and continuously increased until the intussusception is reduced. Thus, it achieves the effect of preventing the input liquid from flowing out and ensuring the stability of the internal pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , a pediatric intussusception enema reduction system, including an ultrasonic device 1, an operation console 2 and a colon insufflator 3. The ultrasonic device 1 and the colon insufflator 3 are respectively arranged on two side edges of the operation console 2. The ultrasonic device 1 is used to detect the intussusception condition of the intestine in the patient's body. Through ultrasonic imaging, doctors can clearly observe the internal condition of the intestine, providing accurate positioning and guidance for enema reduction. The operation console 2 serves as the operation platform for the entire enema reduction process, used to place and fix devices such as the ultrasonic device 1 and the colon insufflator 3. Ensure that the enema reduction process can proceed stably and orderly, and at the same time provide a comfortable position for the patient. The colon insufflator 3 is used to inject liquid or gas into the intestine to assist in intussusception reduction. By controlling the injection volume and speed of the liquid, as well as the inflation volume and pressure of the gas, ensure the safety and effectiveness of the enema reduction process.

[0023] The colon insufflator 3 is respectively provided with a water injection hose 6 and an air injection hose 8. The water injection hose 6 and the air injection hose 8 are respectively used to transport enema fluid and gas into the interior of the intestine and the interior of the airbag 5. The water injection hose 6 accurately delivers the enema fluid to the intestine to assist in the reduction of intussusception; the air injection hose 8 is responsible for inflating the airbag 5 so that the airbag 5 blocks the intestine to prevent the enema fluid from overflowing. The end of the water injection hose 6 is provided with an anal tube 11. The anal tube 11 serves as the inlet for the enema fluid and gas and is inserted into the patient's anus. Ensure that the enema fluid can directly reach the interior of the intestine for intussusception reduction and fix the airbag 5. An airbag 5 is provided in the middle of the anal tube 11. The airbag 5 prevents the enema fluid from overflowing from the intestine during the enema process. When the airbag 5 is inflated, it will closely adhere to the inner wall of the intestine to form an effective seal to prevent the enema fluid from overflowing. An intestinal pressure sensor 7 is provided at one end of the anal tube 11 extending into the intestine. The other end of the air injection hose 8 is communicated with the airbag 5. An external pressure sensor 10 is provided at the end of the hose near the airbag 5. The intestinal pressure sensor 7 and the external pressure sensor 10 respectively monitor the pressure inside the intestine and the pressure inside the airbag 5. By providing real-time feedback of the pressure data, the doctor can accurately control the injection speed and amount of the enema fluid, as well as the inflation amount of the airbag 5, to ensure the safety and effectiveness of the enema reduction process. A valve 9 is provided at the end of the hose far from the airbag 5, and a control center 4 is provided on the colon insufflator 3. The intestinal pressure sensor 7 and the external pressure sensor 10 are data-connected to the control center 4. The control center 4, as the core of the entire system, is responsible for collecting and processing sensor data and controlling the operation of the colon insufflator 3. Through the control center 4, the doctor can understand the pressure changes inside the intestine in real time, accurately control the injection of the enema fluid and the inflation process of the airbag 5, and ensure the safety and effectiveness of the enema reduction.

[0024] An internal spring 51 is provided inside the airbag 5. The installation direction of the internal spring 51 is the same as the direction of the anal tube 11. The internal spring 51 restricts the deformation state of the airbag 5 when it is inflated, causing it to expand mainly in the up and down directions. Ensure that the airbag 5 can tightly press against the inner wall of the intestine to form an effective seal to prevent the enema fluid from overflowing. The elastic force of the internal spring 51 is greater than the expansion force generated when the airbag 5 expands. Such a design can ensure that the shape of the airbag 5 can be restricted by the internal spring 51 during the expansion process, and it will not tend to be spherical due to excessive pressure inside the airbag 5, thereby reducing the sealing effect of the airbag 5 on the intestine.

[0025] The valve 9 is a manual valve or an electronic valve, and the valve 9 is data-connected to the control center 4. The valve 9 controls the opening and closing of the gas injection hose 8, thereby controlling the inflation process of the airbag 5. The manual valve needs to be manually operated to be opened and closed, while the electronic valve can be remotely controlled through the control center 4 to achieve more accurate pressure control. When the pressure inside the intestine continues to increase and the pressure inside the intestine is about to be greater than the pressure generated by the airbag 5 on the inner wall of the intestine, the control center 4 will open the electronic valve, and then the colon injector 3 will inflate the airbag 5, so that the pressure generated by the airbag 5 on the inner wall of the intestine is always greater than the pressure inside the intestine, thereby achieving a faster and more accurate change in the pressure inside the airbag 5.

[0026] Working principle: When in use, the patient lies on the operating table 2 on the side or flat. The ultrasonic device 1 is used to detect the intestinal intussusception in the patient's body, and the data is collected by the control center 4 after the examination. At this time, the anal tube 11 is inserted 10 cm - 20 cm into the patient's anus. The colon injector 3 is started to first inflate the airbag 5, so that the airbag 5 bulges to block the intestine and prevent liquid from overflowing during subsequent liquid injection. Since there is an internal spring 51 in the airbag 5 that is opposite to the anal tube 11, when the airbag 5 is inflated, if there is no tension force of the internal spring 51 on the airbag 5, the airbag 5 will expand in all directions. At this time, the pressure at the contact area between the airbag 5 and the inner wall of the intestine is not concentrated enough, and the pressure formed inside the airbag 5 is not concentrated enough, which is likely to cause liquid overflow; when there is the tension force of the internal spring 51, the deformation state of the airbag 5 will be restricted, so that it does not expand in the left and right directions during expansion, but expands in the up and down directions. At this time, the airbag 5 will be expanded into a disc shape, and the side of the disc-shaped airbag 5 will tightly press against the inner wall of the intestine, and the pressure generated inside the airbag 5 will also be concentrated on the contact area with the inner wall of the intestine, thereby preventing liquid overflow. When the airbag 5 is inflated to a certain extent, the valve 9 is closed, and the pressure inside the airbag 5 is recorded by the external pressure sensor 10 and transmitted to the control center 4, and the pressure of the airbag 5 on the inner wall of the intestine is calculated. Then, liquid is injected into the patient's body through the colon injector 3 and the water injection hose. After injecting for a certain period of time, a certain pressure will be generated in the patient's intestine, and the value of this pressure is recorded by the intestinal pressure sensor 7 and transmitted to the control center 4. When the pressure inside the intestine continues to increase and the pressure inside the intestine is about to be greater than the pressure generated by the airbag 5 on the inner wall of the intestine, it indicates that if liquid is injected at this time, liquid overflow may occur. At this time, the valve 9 is opened, and the control center 4 controls the colon injector 3 to inflate the airbag 5 again, so that the pressure of the airbag 5 on the inner wall of the intestine increases and is always greater than the pressure inside the intestine, so that the liquid cannot overflow, ensuring that the pressure inside the intestine is stably and continuously increased until the intussusception is reduced. After reduction, the valve 9 is opened to deflate the airbag 5, and then the anal tube 11 is gently removed.
