Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a high-efficiency gastric lavage device for patients with acute poisoning. Background Technology

[0002] Acute poisoning refers to the ingestion of an excessive amount of a toxic substance within a short period, resulting in severe discomfort or organ damage. Poisoning can be caused by a variety of factors, including accidental ingestion of poisonous plants, overdose of medications, and exposure to industrial chemicals. The symptoms and severity of acute poisoning depend on the type and dosage of the toxin ingested, as well as the individual's health condition. Mild poisoning may only manifest as nausea, vomiting, headache, or diarrhea, while severe poisoning can lead to loss of consciousness, respiratory distress, and even death. Common poisoning substances include carbon monoxide, heavy metals, pesticides, and certain medications. Less common poisonings may involve specific industrial chemicals or rare natural toxins.

[0003] Despite continuous advancements in gastric lavage technology, existing patented solutions still have several significant drawbacks, primarily in terms of operational efficiency, patient safety and comfort, and system integration. Many traditional or existing gastric lavage devices lack effective patient fixation and automatic position adjustment systems. Gastric lavage requires patients to maintain a specific left lateral decubitus position. For patients who are unconscious, agitated, or vomiting, at least one medical staff member is required to maintain the position and fix the head. This not only consumes valuable human resources but also makes manual fixation laborious and unstable, easily leading to increased risks of patient slippage, gastric tube dislodgement, or aspiration. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a high-efficiency gastric lavage device for patients with acute poisoning.

A first knob is fixedly connected to one end of the double-threaded screw.

[0010] As a preferred embodiment of the present invention, the gastric lavage mechanism includes a water tank fixedly connected to the surface of the base plate. A partition plate is embedded on the surface of the water tank, and the water tank is partitioned to separate its internal space through the partition plate.

[0015] Compared with the prior art, the advantages of this invention are: (1) This invention integrates the electric adjustable bed, back support mechanism, face limiting mechanism, leg limiting mechanism and electric adjustable bed into one unit, so that medical staff do not have to struggle with uncooperative patients. It can stabilize the patient in the standard left lateral decubitus position in a short time and fix the head firmly in the best intubation position. It frees at least one medical staff from the heavy physical fixation work, so that they can focus on intubation, equipment operation and condition observation. It truly reflects the speed requirement of the rescue of acute poisoning. In terms of safety, the multi-mechanism coordinated fixation ensures that the core position will not shift during the whole gastric lavage process, regardless of whether the patient struggles unconsciously. It greatly reduces the risk of gastric tube entering the trachea, gastric tube dislodgement and aspiration pneumonia caused by gastric contents. At the same time, it avoids fatigue and negligence of manual maintenance.

[0016] (2) This invention divides the interior of the water tank into clean water and wastewater chambers and fixes them to the main body of the gastric lavage machine to form an independent liquid circulation module. This changes the messy mode that requires temporary connection of multiple external tubing in the traditional way, making the operating environment clean and reducing the risk of pipeline connection errors and cross-contamination. It meets the requirements of hospital infection control. The water level observation tube makes the balance of inflow and outflow liquid volume a direct comparison of liquid levels. Nurses can clearly judge whether there is gastric fluid accumulation or excessive suction during operation, so as to intervene in time and effectively prevent serious complications such as gastric dilatation or mucosal damage caused by improper fluid management.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example: Please see Figure 1-8 A high-efficiency gastric lavage device for acute poisoning patients includes: a base plate 1, an electrically adjustable bed 2 fixedly connected to the surface of the base plate 1, a back support mechanism 3 fixedly connected to the surface of the electrically adjustable bed 2, a face limiting mechanism 4 fixedly connected to the surface of the back support mechanism 3, a headrest 5 adapted to the face limiting mechanism 4 fixedly connected to the surface of the back support mechanism 3, a gastric lavage mechanism 6 fixedly connected to one side of the base plate 1, a blocking mechanism 7 fixedly connected to the other side of the electrically adjustable bed 2, and a leg limiting mechanism 8 provided on the upper surface of the electrically adjustable bed 2.

[0021] In a specific embodiment of the present invention, the base plate 1 serves as a stable base, on which the electrically adjustable bed 2 is fixed for carrying and raising / lowering the patient as a whole. The back support mechanism 3 and the face limiting mechanism 4 work together to ensure that the patient's head and upper body are in a stable position that meets medical requirements during the gastric lavage process. The headrest 5 provides comfortable support. The gastric lavage mechanism 6 is independently set on one side and is responsible for performing the core flushing and suction functions. The blocking mechanism 7 is located on the other side to prevent the patient from falling when unconscious or struggling. The leg limiting mechanism 8 is used to fix the patient's lower limbs to prevent them from moving around and interfering with the operation or causing self-harm. The entire system is integrated through the electrically adjustable bed 2 to realize an integrated process from patient transfer and positioning to gastric lavage.

[0022] Specifically, the back support mechanism 3 includes a support base 301 fixedly connected to the surface of the electric adjustable bed 2. A rotating plate 302 is rotatably connected to the surface of the support base 301. Two first sliding seats 303 are horizontally slidably connected inside the support base 301. A transmission rod 304 is rotatably connected to the top of the first sliding seat 303, and the tops of the two transmission rods 304 are rotatably connected to the rotating plate 302. Two first threaded rods 305 are rotatably connected inside the rotating plate 302, and the two first sliding seats 303 are respectively threaded to the surfaces of the two first threaded rods 305. Synchronous pulleys 306 are fixedly connected to the surfaces of the two first threaded rods 305, and the two synchronous pulleys 306 are connected by a synchronous chain 307. A first servo motor 308 is fixedly connected to the surface of the support base 301, and the output shaft of the first servo motor 308 is fixedly connected to one of the first threaded rods 305.

[0023] In a specific embodiment of the present invention, the support base 301 is fixed to the bed, the rotating plate 302 serves as the patient's backrest, and the first servo motor 308 drives one first threaded rod 305 to rotate, which in turn drives another first threaded rod 305 to rotate synchronously via the synchronous wheel 306 and the synchronous chain 307. The rotation of the two first threaded rods 305 drives two first sliding seats 303, which are respectively threaded to them, to slide horizontally in opposite directions within the support base 301. The movement of the first sliding seats 303 is converted into a change in the tilt angle of the rotating plate 302 through the transmission rod 304 hinged at the top, thereby realizing... The continuously variable electric adjustment of the back support angle is faster and less strenuous than manual adjustment, which is crucial in time-sensitive emergency situations. Secondly, the mechanical transmission via the first threaded rod 305 and the transmission rod 304 smoothly lifts the patient's back to the required specific angle and maintains absolute stability, preventing aspiration or operational difficulties caused by slippage during gastric lavage. The synchronous design of the dual first threaded rods 305 ensures consistent lifting and lowering on both sides of the rotating plate 302, resulting in even force distribution and avoiding patient distortion or discomfort that may occur with unilateral support, thus improving patient comfort and safety. This design makes it possible to quickly and accurately achieve the optimal position required for gastric lavage.

[0024] Specifically, the face limiting mechanism 4 includes a mounting bracket 401 fixedly connected to the surface of the rotating plate 302. A second sliding seat 402 is horizontally slidably connected to the surface of the mounting bracket 401. An electric push rod 403 for longitudinal adjustment is fixedly connected to the surface of the second sliding seat 402. A connecting seat 404 is fixedly connected to the surface of the piston rod of the electric push rod 403. A limiting mask 406 is fixedly connected to the bottom of the connecting seat 404. A guide rod 405 is fixedly connected to the surface of the connecting seat 404, and the guide rod 405 is slidably connected to the surface of the electric push rod 403. A second threaded rod 407 is rotatably connected to the surface of the mounting bracket 401, and the second sliding seat 402 is threadedly connected to the second threaded rod 407. A second servo motor 408 for driving the second threaded rod 407 is fixedly connected to the surface of the mounting bracket 401. A limit plate 411 is fixedly connected to the surface of the limiting mask 406. Through holes 412 are opened on the surfaces of the limiting mask 406 and the limiting plate 411. Two clamping plates 413 are slidably connected to the surface of the limiting plate 411. A buffer pad 414 is opened on the inner side of the clamping plate 413. A double threaded rod 409 is rotatably connected to the back of the limiting plate 411. The two clamping plates 413 are respectively threaded to the surfaces of the two threads of the double threaded rod 409. A first knob 410 is fixedly connected to one end of the double threaded rod 409.

[0025] In a specific embodiment of the present invention, the mounting bracket 401 is fixed on the rotating plate 302. The second servo motor 408 drives the second threaded rod 407 to rotate, causing the threaded second sliding seat 402 to move horizontally along the mounting bracket 401, thereby driving the entire limiting assembly to adjust laterally. The electric push rod 403 is responsible for performing longitudinal lifting and lowering. Its piston rod extends or retracts, causing the connecting seat 404 and the limiting mask 406 to move closer to or away from the patient's face. The guide rod 405 ensures smooth movement. The limiting mask 406 drives the double threaded screw 409 by rotating the first knob 410, causing the two clamping plates 413 with buffer pads 414 to move towards each other, thereby gently and firmly clamping the gastric tube. The through-hole 412 on the mask and limiting plate 411 provides a dedicated channel for gastric tube insertion. The through-hole 412 guides the gastric tube path, reducing the risk of compression and damage to the tissues around the mouth and nose. Through horizontal and vertical adjustment, the gastric tube inlet can be accurately aligned with the patient's mouth. There is no need for another nurse to laboriously maintain the patient's head position during intubation. The clamping plate 413 effectively restricts the patient's head from swinging left and right and backward, providing the nurse with a clear and undisturbed operating field of vision and channel, significantly reducing the difficulty of intubation. Especially when the patient's jaw is clenched or there is slight struggle, the mechanism can adapt to patients with different head shapes and face shapes, achieving personalized fixation.

[0026] Specifically, the gastric lavage mechanism 6 includes a water tank 601 fixedly connected to the surface of the base plate 1. A partition plate 602 is embedded on the surface of the water tank 601, which divides its internal space. The gastric lavage machine body 603 is fixedly connected above the water tank 601. A booster pump 604 is fixedly connected to the surface of the gastric lavage machine body 603. A first connecting pipe 605 is fixedly connected to the surface of the gastric lavage machine body 603. A connector 606 is fixedly connected to the surface of one end of the first connecting pipe 605. Two water level observation pipes 607 are fixedly connected to the surface of the water tank 601. Two drain valves 608 are fixedly connected to the surface of the water tank 601. The gastric lavage machine body 603 and the booster pump 604 are respectively connected to the water tank 601 through a second connecting pipe 609 and located on both sides of the partition plate 602.

[0027] In a specific embodiment of the present invention, the water tank 601 is divided into a clear water chamber and a wastewater chamber by a partition plate 602. The gastric lavage machine body 603 generates power based on positive and negative pressure pumps to control the circulation and flushing of the gastric lavage fluid. During operation, a booster pump 604 may be used to ensure stable flow. The gastric lavage machine body 603 draws gastric lavage fluid from the clear water chamber through a second connecting pipe 609. After being pressurized by the gastric lavage machine body 603, it is injected into the patient's gastric tube through a first connecting pipe 605 and a connector 606. Subsequently, the gastric lavage machine body 603 switches to negative pressure mode, drawing back the gastric mixture through the same pipeline, and then draining it into the wastewater chamber through another second connecting pipe 609. The observation tube 607 is used to visually monitor the consumption of clean water and the amount of wastewater, while the drain valve 608 is used for final drainage. Clean water and wastewater circulate within the device, avoiding the chaos and ground pollution caused by the need to prepare multiple buckets and frequently change connecting pipes in traditional operations. This maintains a clean rescue environment. The integrated design reduces preparation steps, allowing medical personnel to quickly begin gastric lavage after connecting the tubing, which aligns with the principle that every second counts in the rescue of acute poisoning. The water level observation tube 607 makes fluid balance management intuitive, which is a key safety measure to prevent fluid accumulation in the stomach or excessive suction. The partition design also avoids accidental mixing of clean water and wastewater.

[0028] Specifically, the blocking mechanism 7 includes a blocking frame 701 fixedly connected to the other side surface of the electric adjusting bed 2. An adjusting baffle 702 is slidably connected to the surface of the blocking frame 701 longitudinally. Two hinge rods 703 are slidably connected inside the blocking frame 701, and the top of the hinge rods 703 is fixedly connected to the adjusting baffle 702. Two guide plates 704 for guiding the hinge rods 703 are fixedly connected to the surface of the blocking frame 701. Two half-tooth discs 705 are rotatably connected inside the blocking frame 701, and the two half-tooth discs 705 are rotatably connected to the two hinge rods 703 respectively. A rotating shaft 706 is rotatably connected to the surface of the blocking frame 701. A transmission worm gear 707 meshing with the rotating shaft 706 is fixedly connected to the surface of the rotating shaft 706. A second knob 708 is fixedly connected to one end of the rotating shaft 706.

[0029] In a specific embodiment of the present invention, the blocking frame 701 is fixed to the edge of the bed. Rotating the second knob 708 drives the rotating shaft 706 to rotate, and the transmission worm gear 707 on it drives the half-tooth disk 705 meshing with it to rotate. The rotational motion of the half-tooth disk 705 is converted into a vertical linear motion through the hinge rod 703 that is hinged to it. The two hinge rods 703 rise and fall synchronously under the constraint of the guide plate 704, thereby driving the adjusting baffle 702 fixed on their top to rise or fall. The worm gear mechanism has a self-locking characteristic. Once the adjustment is in place, the baffle position is locked. This mechanism provides adjustable, reliable and space-saving safety protection. The adjusting baffle 702 can be adjusted in height according to the patient's body size and position. It can be raised during gastric lavage to effectively prevent unconscious or convulsing patients from rolling off the side of the bed. It can be lowered after the operation to facilitate patient transfer and access for medical staff.

[0030] Specifically, the leg limiting mechanism 8 includes a tray 801 disposed on the upper surface of the electric adjustable bed 2. The surface of the tray 801 is provided with two limiting elastic bands 802. A waterproof band 803 is fixedly connected to the surface of the limiting elastic bands 802. An insert block 804 is fixedly connected to one end of the inner side of the limiting elastic bands 802. A locking block 805 adapted to the insert block 804 is fixedly connected to the surface of the tray 801. A plurality of limiting holes 806 are opened on the surface of the tray 801. A locking block 807 adapted to the limiting holes 806 is fixedly connected to the surface of the limiting elastic bands 802.

[0031] In a specific embodiment of the present invention, the support plate 801 is placed under the patient's leg. The limiting elastic band 802 has a waterproof band 803, and the insertion block 804 at one end can be inserted into the locking block 805 to fix the first end. Then, according to the thickness of the patient's leg, the elastic band is wrapped around the leg, and the locking block 807 on its surface is inserted into the appropriate limiting hole 806 on the support plate 801 to complete the fixation. By selecting different limiting holes 806, the tightness of the fixation can be adjusted. This design achieves fast and humane lower limb fixation. The fixation using the insertion block 804, locking block 805, limiting hole 806 and locking block 807 is faster and more secure than traditional binding strap knots or Velcro, making it suitable for emergency scenarios. The materials of the limiting elastic band 802 and the waterproof band 803 provide moderate restraint, which can prevent the patient from bending their knees and struggling or kicking, without causing blood circulation obstruction or skin injury, reflecting humanistic care.

[0032] A method for using a high-efficiency gastric lavage device for patients with acute poisoning includes the following steps: Medical staff moved the poisoned patient onto the electrically adjustable bed 2, activated the back support mechanism 3, and the first servo motor 308 worked. By adjusting the rotating plate 302 to a suitable tilt angle, the patient's body was placed in a stable left lateral decubitus position, which could delay the entry of gastric contents into the duodenum and reduce the risk of aspiration. At the same time, the face limiting mechanism 4 was operated. The limiting mask 406 was moved to the front of the patient's face through the second servo motor 408 and the electric push rod 403, with the through hole 412 aligned with the mouth. The head pillow 5 provided neck support. Then, the limiting elastic band 802 of the leg limiting mechanism 8 was used to fix the patient's two lower limbs to the support plate 801. According to the patient's condition, the height of the baffle of the blocking mechanism 7 was adjusted, and the bed side protection was raised. Thus, the patient was safely, comfortably and accurately fixed in the optimal gastric lavage position within a few minutes, laying a solid foundation for subsequent operations. The gastric lavage procedure then begins. The nurse inserts the lavage tube through the through-hole 412 of the facial restraint mechanism 4, and rotates the first knob 410 to gently and firmly secure the lavage tube with the clamping plate 413. Since the head is completely secured, the insertion process is smoother. The lavage tube is then connected to the gastric tube connection port of the lavage machine body 603 in the lavage mechanism 6 via the connector 606. The lavage machine body 603 serves as the core; after startup, the machine first suctions out some of the high-concentration toxins from the stomach, then the machine automatically cycles, the positive pressure pump starts, and the water tank 601... The appropriate lavage fluid, heated to 35-37℃ in a water bath, is injected into the stomach at a controllable pressure and set volume in the clear water chamber. After the injection stops, the negative pressure pump is switched on to aspirate the mixed fluid in the stomach into the waste water chamber. This flushing and aspiration cycle is repeated. The nurse closely monitors the balance of inflow and outflow through the water level observation tube 607, which is the key to preventing acute gastric dilatation or gastric fluid accumulation. The sensors and control system on the gastric lavage machine body 603 monitor the pressure in real time to ensure safety. Throughout the gastric lavage process, the patient's stable position avoids displacement or aspiration of the gastric tube due to agitation. When the lavage fluid is clear and odorless, it indicates that the gastric lavage is basically complete. At this time, an antidote or laxative can be injected through the gastric tube. After completion, fold the end of the gastric tube back, instruct the patient to take a deep breath and pull it out quickly. Finally, lower the baffle of the blocking mechanism 7, loosen the leg limiting mechanism 8 and the face limiting mechanism 4, and restore the back support mechanism 3 to the horizontal position. The patient can then be moved away and sent to the ward for observation.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
