[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0024] Example:

[0025] Please refer to Figure 1-3 The present embodiment provides an intelligent gastrointestinal decompression device based on dynamic regulation of negative pressure, which includes a pressure regulating chamber, which is connected to a pressure chamber via a connecting pipe, and a pressure tube is connected to the pressure chamber; a marking droplet is provided in the pressure tube; a first pressure plate and a second pressure plate are provided in the pressure regulating chamber, and a return spring is provided between the first pressure plate and the second pressure plate; a telescopic rod is provided on the outer side of the second pressure plate, and a first valve and a second valve are provided on the connecting pipe and the pressure regulating chamber respectively; a controller is provided on the pressure regulating chamber, and the controller is electrically connected to the first valve, the second valve and the telescopic rod.

[0026] The existing gastrointestinal decompression device has a complex structure, is not convenient for frequent liquid extraction operations, and has high treatment costs, which greatly increases the economic burden on patients and the workload of medical staff. The present invention sets a pressure tube and observes the position of the marked droplets. When the suction mechanism performs negative pressure suction, the gastrointestinal pressure can be well monitored. When the patient's gastrointestinal pressure is sufficient, the drainage can be completed without installing a connecting power mechanism, which greatly increases the adaptability of the device and reduces the cost of using the device, making it disposable and clean and convenient. A reset spring is set between the first pressure plate and the second pressure plate, so that when the telescopic rod controls the movement of the second pressure plate to adjust the negative pressure, the reset spring acts on the first pressure plate, making the pressure adjustment and negative pressure process smoother and avoiding a sudden increase in pressure in a short time.

[0027] In some embodiments of the present invention, the pressure tube is wound around the outside of the pressure chamber, and its inner diameter is smaller than that of the connecting tube. The smaller inner diameter of the pressure tube allows the expansion and contraction of the air within it to cause a greater displacement of the marker droplet when pressure changes, resulting in more accurate pressure measurements.

[0028] In some embodiments of the present invention, the pressure tube is made of a transparent material, and scale lines are provided on the outside of the pressure tube; the marker droplet has a color. The scale lines facilitate observation of the displacement of the marker droplet.

[0029] In some embodiments of the present invention, a pressure-reducing head is provided at the inner end of the connecting tube. The pressure-reducing head comprises an inner head and an outer head. The outer head is disposed on the outer side of the inner head. The inner head is provided with multiple openings that communicate with the pressure-reducing tube, and the outer head is provided with multiple vertical through-holes that communicate with the openings. By providing the pressure-reducing head, when negative pressure is applied to the gastrointestinal tract through the openings, the outer head, supported by the inner head, effectively separates the gastrointestinal tissue, preventing direct contact with the openings and blockage, and also preventing damage to the patient's tissues.

[0030] In some embodiments of the present invention, the outer sleeve is made of a rubber material and has a thickness of 1-2 cm. This 1-2 cm thickness of the outer sleeve 2 does not hinder insertion. The outer sleeve 2 made of rubber effectively prevents damage to the patient during suction and insertion of the decompression tube 4. The interior of the outer sleeve 2 is hollow. This hollow interior provides a certain degree of elasticity, allowing for a certain degree of deformation and providing strong adaptability.

[0031] In some embodiments of the present invention, the second valve is detachably connected to a collection tube, the end of which is provided with a threaded cap that is threadedly connected to the outer side of the second valve; the collection tube is connected to a collection bottle. The detachable connection between the collection tube and the collection bottle facilitates the collection of body fluids extracted by negative pressure aspiration.

[0032] In summary, the embodiment of the present invention is an intelligent gastrointestinal decompression device based on negative pressure dynamic regulation, which includes a pressure regulating chamber, the pressure regulating chamber is connected to a pressure chamber via a connecting pipe, and a pressure tube is connected to the pressure chamber; a marking droplet is provided in the pressure tube; a first pressure plate and a second pressure plate are provided in the pressure regulating chamber, and a reset spring is provided between the first pressure plate and the second pressure plate; a telescopic rod is provided on the outside of the second pressure plate, a first valve and a second valve are provided on the connecting pipe and the pressure regulating chamber respectively, and a controller is provided on the pressure regulating chamber, and the controller is electrically connected to the first valve, the second valve and the telescopic rod. The present invention can monitor the gastrointestinal pressure well when the suction mechanism performs negative pressure suction by setting a pressure tube and observing the position of the marking droplet. When the patient's gastrointestinal pressure is sufficient, the drainage can be completed without installing a connecting power mechanism, which greatly increases the adaptability of the device and reduces the cost of using the device, making it disposable, clean and convenient. A return spring is installed between the first and second pressure plates. When the telescopic rod controls the movement of the second pressure plate to adjust the negative pressure, the return spring acts on the first pressure plate, making the pressure adjustment and negative pressure process more gradual and avoiding sudden pressure increases. At the same time, by providing a pressure reducing head, when negative pressure is reduced in the gastrointestinal tract through the opening, the outer sleeve supported by the inner head can effectively isolate the gastrointestinal tissue, avoiding direct contact with the opening and blockage, and also preventing damage to the patient's tissues.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
