Description

Technical Field

[0001] The present invention relates to the field of gastric lavage machines, in particular to a gastric lavage machine for gastroenterology. Background Art

[0002] A gastroenterology gastric lavage machine is a vital device used in gastroenterology treatments, primarily for removing toxic substances, drug residues, and food debris from the patient's stomach. Hospitals at all levels often use gastric lavage to remove harmful substances from the stomach during the treatment of oral poisoning. The gastroenterology gastric lavage machine primarily relies on an electromagnetic pump as its power source. Controlled by an automatic circuit, the solenoid valve automatically switches its operation, flushing the medication into the stomach and aspirating the stomach contents. This process automatically, rapidly, and thoroughly removes toxins from the stomach, reducing their absorption into the body and allowing time for further treatment.

[0003] When using a gastric lavage machine to clean the patient's stomach, there is also the situation of increased gastric resistance. Increased gastric resistance means that the gastric lavage fluid is difficult to enter and flow out of the gastric cavity smoothly, resulting in insufficient mixing of the gastric lavage fluid and gastric contents, thereby reducing the gastric lavage effect and failing to effectively remove toxic substances, drug residues or food residues in the stomach. This may delay the treatment of the disease and even cause the disease to worsen. In addition, when the gastric resistance increases, if the pressure or flow of the gastric lavage machine is forcibly increased, the stomach wall may be subjected to excessive pressure, leading to gastric perforation.

[0004] At present, most cases of increased internal resistance in the stomach are mainly due to the high pressure caused by excessive food in the stomach and the increased internal resistance of the stomach caused by gastric wall spasm. In order to quickly and promptly determine the cause of the increased internal resistance when the internal resistance of the stomach increases, it is impossible to adjust the pressure and flow of the gastric lavage machine in time. For this purpose, a gastroenterology gastric lavage machine is proposed. Summary of the Invention

The expansion and contraction components cooperate with the adjustment components to achieve expansion and contraction movement inside the extraction tube, so as to more accurately sense the situation inside the stomach.

[0035] See also Figure 1 - Figure 12A gastroenterology gastric lavage machine includes a gastric lavage body 1, which has an injection tube 101 and an extraction tube 2; a detection probe 3, which is arranged inside the injection tube 101 and supported by a supporting plate 11, and a telescopic component 5 and an adjustment component 6 are provided in the extraction tube 2, and the telescopic component 5 and the adjustment component 6 cooperate with each other and control the telescopic movement of the detection probe 3 for detection. A matching extrusion structure and a reset structure are provided between the supporting plate 11 and the telescopic component 5 for adjusting the detection probe 3.

[0036] In a specific embodiment, the gastric lavage machine for gastroenterology is mainly composed of three core components: a gastric lavage body 1, an injection tube 101 and an extraction tube 2. During operation, first, by connecting the extraction tube 2 and the injection tube 101, a channel for injecting gastric lavage fluid and extracting gastric contents is constructed, and the start and setting are as follows: open the control unit of the gastric lavage body 1, adjust the temperature and flow parameters of the gastric lavage fluid according to clinical needs, and inject the set gastric lavage fluid into the patient's stomach through the injection tube 101. At the same time, the extraction tube 2 is responsible for extracting the contents of the stomach. At this time, a detection element detection probe 3 that can be monitored in real time is provided inside the extraction tube 2. When needed, the element can be extended to the end of the extraction tube 2 to directly contact the stomach wall or gastric contents. The detection probe 3 is supported by the support plate 11 and remains stable in the extraction tube 2. The telescopic component 5 and the adjustment component 6 cooperate with each other to achieve telescopic movement inside the extraction tube 2. This design allows the detection probe 3 to be extended when needed to more accurately sense the situation in the stomach. When encountering When the intragastric resistance increases due to gastric wall spasm, the contracting stomach will squeeze the detection probe 3, thereby triggering the control unit gastric lavage body 1 to reduce the pressure and flow of the gastric lavage fluid to avoid further damage to the patient's stomach. If the intragastric resistance increases but the detection probe 3 is not subjected to obvious pressure, it is judged that the resistance is caused by food in the stomach. At this time, the gastric lavage body 1 will automatically increase the pressure and flow to ensure that the gastric lavage fluid can be effectively injected and the gastric contents can be extracted. In order to prevent misjudgment, a matching squeezing structure and a reset structure are also provided between the detection probe 3 and the extraction tube 2. These structures allow the position of the detection probe 3 to be adjusted in all directions to more accurately judge whether there is a real problem of increased resistance in the stomach, thereby improving the accuracy of the detection process. The structural design of the entire gastric lavage machine is compact, and all moving parts are cleverly hidden inside the extraction tube 2. This design is not only convenient for rapid deployment for detection after insertion into the patient's body, but also can be quickly retracted after the detection is completed to save space, improve the convenience of operation and the comfort of the patient.

[0037] Among them, the detection probe 3 is a detection component that needs to use a soft, corrosion-resistant and biocompatible material, such as medical-grade silicone or polyurethane, to ensure that it will not cause damage to the stomach wall when inserted into the stomach, and can work stably in the stomach environment. At the same time, the detection probe 3 set can adapt to the morphological changes of the stomach and ensure that the sensor can stick to the stomach wall for accurate measurement; the structural design of the detection probe 3 is integrated with a pressure sensor, and a high-sensitivity pressure sensor is embedded in an appropriate position inside the detection probe 3 for real-time detection of the squeezing force from the stomach wall. During application, the sensor should have good sealing and stability to accurately capture the tiny pressure changes during stomach wall spasms.

[0038] Furthermore, the main structure telescopic assembly 5 is composed of four main components: an outer tube 501, a first telescopic cylinder 502, a second telescopic cylinder 503, and a third telescopic cylinder 504. These components are connected to each other in a nested manner, wherein the first telescopic cylinder 502 is sleeved on the outside of the second telescopic cylinder 503, and the second telescopic cylinder 503 is sleeved on the outside of the third telescopic cylinder 504, and all these components can be retracted into the outer tube 501 to enhance stability during the activity.

[0039] Adjustment component 6: responsible for controlling the telescopic movement between the first telescopic cylinder 502, the second telescopic cylinder 503, and the third telescopic cylinder 504. It consists of three parts: a main threaded rotating rod 601, a first threaded sleeve 602, and a second threaded sleeve 603. It also adopts a nested design, in which the first threaded sleeve 602 is sleeved outside the main threaded rotating rod 601, and the second threaded sleeve 603 is sleeved outside the first threaded sleeve 602.

[0040] Limiting structure 9: ensures the orderly relative telescopic movement between the telescopic component 5 and the adjustment component 6, and consists of a first nut sleeve 901, a second nut sleeve 902, a first limiting structure 903, and a second limiting structure 904, wherein the first nut sleeve 901 and the second threaded sleeve 603, the second nut sleeve 902 and the first threaded sleeve 602 respectively form two nut drivers, and the threaded connection between the third telescopic cylinder 504 and the second threaded sleeve 603 constitutes a third nut driver.

[0041] Working principle: Rotation and extension: By rotating the adjustment component 6 and utilizing the principle of the nut driver, the first telescopic cylinder 502, the second telescopic cylinder 503, and the third telescopic cylinder 504 are driven to move axially. The lengths of the first, second, and third lead wires of each driver are L1, L2, and L3 MM respectively. Therefore, when the adjustment component 6 rotates N circles, the specific components on the second telescopic cylinder 503, such as the limiting protrusion 505, will perform a displacement of N / (L1+L2+L3) MM; the front-end detection probe 3 of the device is set on the cylinder of the third telescopic cylinder 504 through the support of the gastric lavage body 1. The opening is used to detect the situation inside the patient's stomach. When abnormal conditions such as gastric wall spasm are detected, which leads to increased resistance, the built-in sensor of the detection probe 3 will feed back the information to the gastric lavage body 1 so as to adjust the pressure and flow in time to ensure safe and effective operation. The above makes the overall structure compact, and all moving parts are located inside the extraction tube 2, which is convenient for rapid deployment for detection after insertion into the patient's body, and quickly retracted after the detection is completed to save space. It can also accurately control the extension and retraction of the detection component, and at the same time feedback the detection results in real time to adjust the operating parameters to ensure the safety and efficiency of the medical process.

[0042] It should also be noted that the limiting protrusion 505 is respectively installed between the first telescopic cylinder 502, the second telescopic cylinder 503 and the third telescopic cylinder 504. After the first telescopic cylinder 502, the second telescopic cylinder 503 and the third telescopic cylinder 504 are nested, the first telescopic cylinder 502, the second telescopic cylinder 503 and the third telescopic cylinder 504 are each provided with a groove that can cooperate with the limiting protrusion 505 to limit movement and improve stability during the telescopic process.

[0043] Furthermore, the bottom of the telescopic component 5 is connected to the barrel bottom plate 7, the extraction tube 2 and the injection tube 101 are connected by a pipe joint 4, and the adjustment component 6 realizes the telescopic function through a set of precise control components. The core components of this control component include a first rotating rod 8, a first bevel gear 801, a second rotating rod 802, a second bevel gear 803 and a drive component 804. First, the first rotating rod 8 is fixedly mounted on the main threaded rotating rod 601 inside the adjustment component 6, and passes through the barrel bottom plate 7, so that the first bevel gear 801 can be connected to the corresponding position of the barrel bottom plate 7. This design ensures a stable connection between the control component and the main structure. The second bevel gear 803 is installed at the output end of the second rotating rod 802, and the other end of the second rotating rod 802 extends out of the connection part of the extraction tube 2, and the drive component 804 is installed here. Component 804 serves as a power source, which is connected to the second rotating rod 802 and installed on the pipe joint 4, and can drive the second rotating rod 802 to rotate. Since the second rotating rod 802 is directly connected to the second bevel gear 803, when the second rotating rod 802 rotates, it will also drive the second bevel gear 803 to rotate synchronously. It is specially designed that the second bevel gear 803 and the first bevel gear 801 are in a state of mutual meshing. This meshing mechanism ensures that when the driving component 804 drives the second rotating rod 802 to rotate, the rotational force can be transmitted to the first bevel gear 801 through the second bevel gear 803, thereby driving the first rotating rod 8 to rotate. Since the first rotating rod 8 is fixed on the main threaded rotating rod 601 of the adjusting component 6, the rotation drive of the main threaded rotating rod 601 is finally realized, providing the necessary power for the extension and retraction of the adjusting component 6.

[0044] It should also be noted that the entire structure adopts a high-precision connection method to ensure close fit and stable operation between the components. At the same time, the design also fully considers the sealing requirements to prevent liquid or gas leakage that may occur during operation.

[0045] Furthermore, a set of matching extrusion structures and reset structures are designed between the detection probe 3 and the extraction tube 2 to ensure precise control and stability of the detection probe 3 during the extension and retraction process. The extrusion structure consists of an internal ring 10, a first movable groove 1001, a first reset spring 1002 and a second reset spring 1103, wherein the internal ring 10 is installed at the inner tube mouth of the extraction tube 2. As the main bearing component of the extrusion action, the first movable groove 1001 is opened inside the internal ring 10, and the first reset spring 1002 is arranged in the first movable groove 1001. When the supporting plate 11 is set at the end of the third telescopic cylinder 504 and carries the detection probe 3, when the third telescopic cylinder 504 is extended to the front end, the detection probe 3 is driven to extend, which will squeeze the first reset spring 1002 inside the first movable groove 1001. After squeezing, due to the rotational force of the first reset spring 1002, it interacts with the spiral groove designed on the inner movable cylinder 1101, limiting and driving the supporting plate 11 to rotate one circle relative to the internal ring 10 and then move downward.

[0046] The reset structure consists of an inner movable cylinder 1101, a second movable groove 1102 and a second reset spring 1103. The inner movable cylinder 1101 and the supporting plate 11 adopt an integrated structural design to enhance the integrity and stability of the structure. The second movable groove 1102 is opened at the inner cylinder mouth of the third telescopic cylinder 504, providing guidance and support for the downward movement of the supporting plate 11. In the process of the supporting plate 11 moving downward, it drives the inner movable cylinder 1101 to move inside the second movable groove 1102, and at the same time squeezes the second reset spring 1103 set in the second movable groove 1102. When the second reset spring 1103 is subjected to the extrusion force, it will restore the inner movable cylinder 11 through the restoring force. 01 After rotating one circle relative to each other inside the second movable groove 1102, the slider 1004 on the supporting plate 11 is driven to reset. This reset process ensures that the detection probe 3 can accurately return to the initial position and prepare for the next operation. Through the coordinated action of the extrusion structure and the reset structure, the position of the detection probe 3 can be adjusted in all directions. This not only improves the accuracy of judging whether there is a real problem of increased resistance in the stomach during the detection process, but also ensures that after confirming the increase in resistance, the telescopic component 5 and the adjustment component 6 can be quickly and accurately controlled to retract the detection probe 3 into the extraction tube 2. This design not only improves the overall performance of the equipment, but also enhances its practicality and reliability in the field of medical testing.

[0047] It should also be noted that the first return spring 1002 uses its rotational force to produce an effective interaction with the carefully designed spiral groove on the inner movable cylinder 1101 assembly. This design not only realizes the transmission of rotational force, but also may guide a certain specific mechanical motion path. In addition, the upper part of the inner wall of 1103 is equipped with an axis rod, which is closely linked to the movement of the inner movable cylinder 1101 and the second movable groove 1102. When the inner movable cylinder 1101 moves along the internal space of the second movable groove 1102, the axis rod will synchronously move along the preset spiral groove on the inner movable cylinder 1101. This movement not only realizes the precise control of the movement of the inner movable cylinder 1101, but also achieves the purpose of limiting, thereby ensuring the stability and reliability of the entire mechanical structure.

[0048] Furthermore, an additional component outer movable cylinder 12 is installed on the supporting plate 11. The outer movable cylinder 12 is designed to fit tightly on the outer cylinder wall of the third telescopic cylinder 504 and move therewith. Since there is a specific movable interval between the supporting plate 11 and the cylinder mouth of the third telescopic cylinder 504, when the supporting plate 11 moves, whether it is extended or retracted, the outer movable cylinder 12 can relatively maintain a fit state with the outer cylinder wall of the third telescopic cylinder 504. This fit not only ensures the stability of the structure, but also through the close contact between the outer movable cylinder 12 and the outer cylinder wall of the third telescopic cylinder 504, the outer movable cylinder 12 and the sealing ring 1201 arranged inside the outer movable cylinder 12 work together, and utilize the fit movement with the outer cylinder wall of the third telescopic cylinder 504 to ensure the sealing performance of the movable interval between the supporting plate 11 and the cylinder mouth of the third telescopic cylinder 504, effectively blocking the potential leakage path outside the movable interval, thereby ensuring the sealing of the interval.
