Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular is a gastrointestinal decompression device with an anti-blocking function. Background Art

[0002] Gastrointestinal decompression involves inserting a gastric tube through the mouth or nose, connected to a disposable gastrointestinal decompression device, and drawing gastric contents out of the patient's body through the negative pressure and siphon principle. This method can draw out gas or fluid from the gastrointestinal tract, reducing pressure within the tract, reducing gastrointestinal distension, improving blood circulation in the gastrointestinal wall, and promoting wound healing and functional recovery. This can relieve or alleviate symptoms caused by intestinal obstruction; it can also be used for preoperative preparation for gastrointestinal surgery to reduce gastrointestinal flatulence; and it can be used to draw out gas and gastric contents postoperatively, reducing abdominal distension, reducing pain at suture wounds, promoting wound healing, improving blood circulation in the gastrointestinal wall, and promoting recovery of digestive function.

[0003] Traditional gastrointestinal decompression devices usually consist of a single-channel gastric tube, a negative pressure source (such as an aspirator) and connecting pipes. They discharge gastrointestinal contents through negative pressure suction, but there is a risk of single-channel blockage. High-viscosity gastric juice or food residues can easily accumulate in the single channel, leading to complete blockage of the tube lumen. Frequent disassembly and flushing are required, increasing the operational burden on medical staff. Negative pressure control is insufficient. Existing devices mostly rely on external negative pressure regulation equipment and lack an integrated precise pressure regulation mechanism. Excessive negative pressure may damage the mucosa, while too low negative pressure will reduce drainage efficiency. The fixation method is single. Gastric tubes are mostly fixed with tape, which is easy to fall off and difficult to adapt to different patient sizes (such as obese or thin patients).

[0004] Therefore, a gastrointestinal decompression device with an anti-blocking function is proposed to solve the problems raised in the background art. Summary of the Invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a gastrointestinal decompression device with an anti-blocking function.

[0008] an anti-blocking mechanism, located between the catheter and the container, and used to prevent the catheter from being easily blocked when extracting gastric mucus;

[0009] Wherein, the anti-blocking mechanism includes a U-shaped tube, a support block located at the bottom of the U-shaped tube, a fixing frame fixedly arranged at the bottom of the support block and fixedly connected to the side wall of the container, and a pressing assembly arranged on the fixing frame.

[0010] Preferably, one side of the curved surface of the U-shaped tube is fixedly connected to the end of the catheter away from the fixed mask, the U-shaped tube is used to realize the diversion of the catheter, the side of the U-shaped tube away from the catheter is connected to the container, and a pressure sensor is fixedly provided on the inner wall of the end of the catheter close to the U-shaped tube.

[0011] Preferably, the support block is annular and made of rubber material, and is clamped on one end of the catheter close to the U-shaped tube. The support block is used to support the support block and the catheter.

[0012] Preferably, the pressing assembly includes pressing blocks symmetrically arranged on both sides of the catheter close to one end of the U-shaped tube, a connecting frame fixedly installed on the top of the fixing frame, two connecting plates fixedly arranged on the top of the pressing blocks on both sides, two fixed blocks fixedly arranged on the side of the two connecting plates away from the connecting frame, pulleys fixedly arranged on the two fixed blocks, and a driving block located at the top position of the center of the two pulleys.

[0013] Preferably, a rubber pad is fixedly provided on the side where the two pressing blocks are close to each other, and the two rubber pads abut against the catheter. The pressing blocks and the rubber pads are angled on the side close to the catheter, which can initially limit the catheter.

[0014] Preferably, the two connecting plates are inclined plates and are cross-arranged, with a hinged state at the center and a hinged central axis fixedly connected to the connecting frame.

[0015] Preferably, an electric push rod is fixedly provided on the top of the driving block, and the top of the electric push rod is fixedly linked to a connecting frame. The cross section of the connecting frame is L-shaped, and protruding plates are fixedly provided on both symmetrical sides of the connecting frame.

[0016] Preferably, the driving block is composed of a cylinder and a cone and gradually shrinks from top to bottom, and the outer wall of the driving block abuts against the side of the two pulleys that are close to each other.

[0017] Preferably, the two fixing blocks are provided with a reset assembly for driving the bottom pressing block to approach the catheter and squeeze it.

[0018] Preferably, the reset assembly includes a slide rod slidingly passing through the two fixed blocks and two springs sleeved on both sides of the slide rod;

[0019] One end of the two springs that is close to each other is fixedly connected to one side of the two fixed blocks that is away from each other, and the other end is fixedly connected to the protruding plate. The driving block can drive the fixed blocks on both sides to move toward each other.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention facilitates the diversion and anti-blocking of the catheter by arranging the U-shaped tube, the support block and the pressing assembly and other structures. The catheter is inserted into the patient's mouth and nose, and is secured to the face by fixing the mask and the Velcro. The pressure reducer is pressed to generate negative pressure, and the gas and liquid in the gastrointestinal tract are adsorbed and discharged into the container to achieve gastrointestinal treatment. To prevent the catheter from being blocked, the anti-blocking mechanism uses a U-shaped tube for diversion, so that mucus is discharged through a dual channel, reducing the risk of blockage. If the diversion point may still be blocked due to pressure accumulation, the pressing assembly will squeeze the connection between the catheter and the U-shaped tube, and use the hose characteristics of the catheter to deform it, thereby changing the flow state and direction of the internal fluid, effectively reducing the possibility of blockage, and solving the problem that the existing device uses a single catheter for adsorption, has a high risk of blockage, and high-viscosity gastric juice or food residues are easily accumulated in a single channel, resulting in complete blockage of the lumen.

[0022] The present invention facilitates further anti-blocking by arranging the cooperation of structures such as a pressing block, a pressure sensor and a reset assembly. The anti-blocking function is achieved by the pressing assembly. When the connection between the catheter and the U-shaped tube is blocked, the pressure sensor detects abnormal pressure and triggers the electric push rod, driving the conical drive block to move upward, so that the pulleys on both sides lose the extrusion force. The spring of the reset assembly pushes the connecting plate inward to drive the pressing block to squeeze the catheter, changing the direction of the fluid to clear the blockage; if the pressure is normal, the electric push rod moves the drive block downward, the extrusion pulley causes the connecting plate to expand outward, the spring is compressed, and the pressing block moves away from the catheter to restore the initial state.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the present invention provides a gastrointestinal decompression device with an anti-blocking function, comprising a catheter 1, a container 2 being provided at one end of the catheter 1, a pressure reducer 3 being fixedly mounted on one side of the container 2, a connecting pipe 31 being fixedly provided on one side of the pressure reducer 3, the connecting pipe 31 being connected to the container 2, and the pressure reducer 3 being able to achieve a decompression effect by being pressed;

[0034] A fixed mask 4 is located at the end of the catheter 1 away from the container 2. Velcro 41 is fixedly installed on both symmetrical sides of the fixed mask 4. The end of the catheter 1 close to the fixed mask 4 is used to be inserted into the patient's mouth and nose;

[0035] an anti-blocking mechanism 5, which is located between the catheter 1 and the container 2 and is used to prevent the catheter 1 from being easily blocked when extracting gastric mucus;

[0036] Among them, the anti-blocking mechanism 5 includes a U-shaped tube 51, a support block 52 located at the bottom of the U-shaped tube 51, a fixing frame 53 fixedly arranged at the bottom of the support block 52 and fixedly connected to the side wall of the container 2, and a pressing assembly 54 arranged on the fixing frame 53.

[0037] The above scheme is adopted: by inserting the end of the catheter 1 close to the fixed mask 4 into the patient's mouth and nose, and by using the cooperation between the fixed mask 4 and the Velcro 41, the Velcro 41 is adhered to the patient's face to achieve the fixation of the fixed mask 4. At this time, the pressure reducer 3 can be pressed, and the connecting tube 31 can be used to remove the gas inside the patient's gastrointestinal tract according to the principle of negative pressure adsorption to adsorb and discharge the liquid into the container 2 for collection, thereby achieving reasonable treatment of the patient's gastrointestinal tract. In order to avoid the single catheter 1 from being easily blocked during adsorption during the treatment process, In order to solve the phenomenon, the anti-blocking mechanism 5 can be used to reasonably prevent the catheter 1 from being blocked. Specifically, the U-shaped tube 51 is used to divert the catheter 1, thereby reducing the blockage inside the catheter 1 and allowing the mucus to be discharged from two channels. However, since the diversion point between the catheter 1 and the U-shaped tube 51 may be blocked due to the convergence of internal pressure, the pressing component 54 can be used to press the connection between the catheter 1 and the U-shaped tube 51, thereby causing the catheter 1 to deform. The catheter 1 is a hose, thereby realizing the state and flow direction of the fluid inside the catheter 1 and reducing the possibility of blockage.

[0038] like Figures 2 to 6 As shown, one side of the curved surface of the U-shaped tube 51 is fixedly connected to the end of the catheter 1 away from the fixed mask 4. The U-shaped tube 51 is used to realize the diversion of the catheter 1. The side of the U-shaped tube 51 away from the catheter 1 is connected to the container 2. A pressure sensor 511 is fixedly provided on the inner wall of the end of the catheter 1 close to the U-shaped tube 51. The support block 52 is annular and made of rubber. The support block 52 is clamped on the end of the catheter 1 close to the U-shaped tube 51. The support block 52 is used to support the support block 52 and the catheter 1;

[0039] The pressing assembly 54 includes pressing blocks 541 symmetrically arranged on both sides of the end of the catheter 1 close to the U-shaped tube 51, a connecting frame 542 fixedly installed on the top of the fixing frame 53, two connecting plates 543 fixedly installed on the top of the pressing blocks 541 on both sides, two fixing blocks 544 fixedly installed on the side of the two connecting plates 543 away from the connecting frame 542, pulleys 545 fixedly installed on the two fixing blocks 544, and a driving block 546 located at the top position of the center of the two pulleys 545.

[0040] The two pressing blocks 541 are fixedly provided with rubber pads 5411 on the sides close to each other, and the two rubber pads 5411 abut against the catheter 1. The pressing blocks 541 and the rubber pads 5411 are both angled on the sides close to the catheter 1, which can preliminarily limit the catheter 1. The two connecting plates 543 are both inclined plates and are cross-arranged. They are hinged at the center and the central axis of the hinge is fixedly connected to the connecting frame 542. An electric push rod 547 is fixedly provided on the top of the driving block 546. The top of the electric push rod 547 is fixedly linked to the connecting frame 542. The cross-section of the connecting frame 542 is L-shaped, and protruding plates are fixedly provided on the symmetrical sides of the connecting frame 542. The driving block 546 is composed of a cylinder and a cone and gradually shrinks from top to bottom. The outer wall of the driving block 546 abuts against the side of the two pulleys 545 close to each other;

[0041] The two fixing blocks 544 are provided with a reset assembly 548 for driving the bottom pressing block 541 to approach the catheter 1 and squeeze it;

[0042] The reset assembly 548 includes a sliding rod 5481 that slides through the two fixed blocks 544 and two springs 5482 that are symmetrically mounted on both sides of the sliding rod 5481. The ends of the two springs 5482 that are close to each other are fixedly connected to the sides of the two fixed blocks 544 that are away from each other, and the other ends are fixedly connected to the protruding plate. The driving block 546 can drive the fixed blocks 544 on both sides to move toward each other.

[0043] The above solution is adopted: the connection between the U-shaped tube 51 and the catheter 1 is pressed and deformed by the pressing component 54, thereby avoiding blockage of the connection. Specifically, the reset component 548, the driving block 546 and the pressure sensor 511 cooperate to drive the fixed blocks 544 on both sides to move in opposite directions, thereby driving the hinged connecting plate 543 and the two pressing blocks 541 at the bottom to move closer to or away from the connection between the catheter 1 and the U-shaped tube 51, thereby pressing the catheter 1.

[0044] The pressure sensor 511 and the electric push rod 547 are both electrically connected to the external control center. When a blockage occurs inside the catheter 1, the pressure sensor 511 senses that the internal pressure exceeds the preset range and transmits the result to the electric push rod 547. The electric push rod 547 drives the driving block 546 to move upward. Since the bottom of the driving block 546 is conical, when it moves upward, the two pulleys 545 lose the squeezing force. At this time, the springs 5482 on both sides drive the connecting plate 543 to return to the center, and then drive the pressing block 541 on the other side to move closer to each other, so that the rubber pad 5411 contacts and squeezes the catheter 1, changing the direction of the internal fluid.

[0045] When the pressure at the connection between the catheter 1 and the U-shaped tube 51 is within the normal prefabricated range, the driving block 546 moves downward to squeeze the pulleys 545 on both sides, driving the two connecting plates 543 away from each other. At this time, the spring 5482 is in a compressed state, and the two pressing blocks 541 at the bottom move away and lose the squeezing force on the catheter 1. This state is the initial state.

[0046] The working principle and usage process of the present invention are as follows: When using this medical device, the operator first gently inserts the soft catheter 1 into the patient's mouth and nose and securely secures it with a high-fitting Velcro 41 to ensure patient comfort during treatment. After securing, the medical staff activates the high-efficiency pressure reducer 3 to generate a stable negative pressure adsorption force. During this process, the mucus accumulated in the patient's gastrointestinal tract is safely aspirated. This mucus first enters the carefully designed U-shaped tube 51 through the catheter 1. The U-shaped tube adopts a unique dual-channel structure design, which can evenly divert the mucus into two independent channels, and finally into the large-capacity container 2 for centralized collection. This innovative diversion mechanism effectively prevents pipeline blockage. It is particularly worth mentioning that the device is equipped with an intelligent anti-blocking adjustment mechanism at the key part of the shunt system: the precise electric push rod 547 drives the drive block 546 to perform precise up and down reciprocating motion, and at the same time cooperates with the highly sensitive reset component 548 to coordinate the operation, so that the connecting plate 543 can intelligently adjust the spacing, thereby driving the two ergonomically designed pressing blocks 541 at the bottom to accurately squeeze or relax the joint between the catheter 1 and the U-shaped tube 51. This dynamically adjustable pipeline control method can not only change the shape of the pipeline connection in real time, but also intelligently adjust the flow state and direction of the internal fluid. When the pipeline is detected to be blocked, the system can automatically perform dynamic adjustments, significantly improving the pipeline patency, thereby achieving a scientific and intelligent anti-blocking effect, greatly improving the safety and reliability of clinical use.
