Description

Technical Field

[0001] The invention belongs to the technical field of gastric lavage auxiliary equipment, in particular to an emergency gastric lavage nursing auxiliary equipment. Background Art

[0002] Gastric lavage is one of the common and important first aid measures in emergency medicine, mainly used to rescue patients who have orally ingested various toxic substances (such as drugs, poisons, excessive alcohol, etc.). Gastric lavage can quickly remove the unabsorbed poisons in the stomach, reduce the absorption of poisons, and reduce the damage of poisons to important organs of the human body, creating favorable conditions for the patient's subsequent treatment and rehabilitation.

[0003] When performing gastric lavage, you need to first understand the patient's poisoning condition, including the name of the poison, dosage, and time of poisoning, and assess the patient's vital signs, such as blood pressure, heart rate, and respiration. If the patient is in shock, you may need to correct the shock before gastric lavage, and check the patient's oral and nasal mucosa to ensure there is no damage or inflammation, so as to choose the appropriate route for gastric tube insertion;

[0004] When performing gastric lavage, the patient needs to be assisted to take a suitable position, generally lying on the left side, with the head of the unconscious patient tilted to one side to prevent aspiration. Then lubricate the front end of the gastric tube and insert the gastric tube according to the correct operation method. During the insertion process, pay attention to observe the patient's reaction and make adjustments in time; when the gastric tube is successfully inserted, properly fix the gastric tube to prevent it from falling out.

[0005] During the intubation process or gastric lavage, if the gastric tube is pulled by external force, the part of the gastric tube that is not fully inserted will be pulled out of the esophagus, which will not only make the patient uncomfortable, but also require re-insertion of the tube, and prolong the emergency time of gastric lavage, thereby increasing the risk. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art and solve the above technical problems, the present invention proposes an emergency gastric lavage nursing auxiliary device, which can stop the gastric tube by setting a limit component, thereby increasing the difficulty of pulling out the gastric tube and reducing the risk of pulling out the gastric tube. The specific structure is as follows;

[0007] An emergency gastric lavage nursing auxiliary device comprises a gastric tube fixer; the gastric tube fixer comprises an elliptical tube and a circular ring;

[0008] The oval tube is fixedly connected to the circular ring, and the oval tube is used to be placed in the patient's mouth, and the gastric tube passes through the circular ring and the oval tube; a bandage is fixedly connected to the circular ring, and the bandage is used to be tied to the patient's head;

[0015] When inserting the gastric tube, the gastric tube is inserted from the side of the cylinder away from the locking ring, and then the gastric tube passes through multiple arc-shaped spring sheets and rubber layers in sequence. At the same time, the gastric tube squeezes the rubber layer and the arc-shaped spring sheets to bend to opposite sides, and the arc-shaped spring sheets push the rubber layer against the surface of the gastric tube under the action of their own elastic force;

[0016] The outer ring surface of the cylinder is provided with a reinforcement component, and the reinforcement component is used to improve the fixation degree of the gastric tube.

[0017] Preferably, the reinforcement assembly comprises an annular bin;

[0018] The outer ring surface of the cylinder is fixedly connected with an annular bin; a partition is fixedly connected inside the annular bin, and the partition divides the annular bin into two chambers;

[0019] The two chambers are both slidably connected with piston rings; the piston ring close to the locking ring is fixedly connected with push rods arranged evenly, and the push rods all pass through the partition plate and the other piston ring and extend out of the annular chamber;

[0020] The push rod is slidably connected to the partition; the push rod is also fixedly connected to the piston ring on the other side; one side of the plurality of push rods extending out of the annular bin is fixedly connected to a push ring;

[0021] Each of the rubber layers is provided with an air tube; each of the rubber layers is provided with a semicircular groove at the bottom, and the semicircular groove is connected to the air tube;

[0022] An air passage is provided in the cylinder on one side of each air pipe facing the piston ring, and the air passage is communicated with the space on the right side of the piston ring.

[0023] Preferably, the end surface of one side of the annular bin close to the push ring is rotatably connected to a limit plate via a rotating shaft. When the push ring is pushed to fit with the annular bin, the limit plate is rotated to fit with the push ring to limit the push ring.

[0024] Preferably, a slide groove is provided on the inner wall of the cylinder on the left side of each of the air passages, and the slide groove is connected to the space on the left side of the piston ring;

[0025] A push rod is slidably connected in each of the slide grooves, and in an initial state, the push rod extends into the cylinder and fits with the arc-shaped spring sheet.

[0026] Preferably, the four rubber layers on the two limit assemblies are fixedly connected with an annular sleeve on one side facing the locking ring;

[0027] The opening diameter of the annular sleeve on the side close to the rubber layer is larger than the opening diameter of the side away from the rubber layer.

[0028] Preferably, a curved plate is fixedly connected to one side of each of the push rods close to the curved spring piece; and the curved plate is in contact with the surface of the opposite curved spring piece.

[0029] Preferably, a plurality of the arc-shaped plates are close to each other and fit together to form a circular plate, so that the gastric tube can be limited by pushing the arc-shaped spring sheet and the rubber layer, and the gastric tube can be prevented from being flattened.

[0030] Preferably, two extrusion plates are provided on the right side of the push ring on the cylinder; the extrusion plate located below is fixedly connected in the cylinder through a fixing rod;

[0031] A threaded rod is rotatably connected to the extrusion plate located above, and the threaded rod passes through the cylinder and extends to the top of the cylinder; the threaded rod passes through one side of the cylinder and meshes with the cylinder thread.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. The emergency gastric lavage nursing auxiliary equipment described in the present invention is provided with a limit assembly. The arc-shaped spring piece and the rubber layer on the limit assembly can be against the gastric tube. If the gastric tube is pulled by external force, the rubber layers close to each other can hold the gastric tube, thereby limiting the gastric tube from continuing to move in the opposite direction, thereby increasing the force required to pull out the gastric tube, thereby increasing the difficulty of pulling out the gastric tube, thereby avoiding the need to reinsert the gastric tube after it is pulled out, and prolonging the emergency time of gastric lavage, thereby increasing the risk. If the gastric tube is subjected to too much external force, the limit assembly can reduce the length of the gastric tube being pulled out.

[0034] 2. The emergency gastric lavage nursing auxiliary equipment described in the present invention can adsorb the rubber layer on the gastric tube by extracting the gas in the trachea and the airway, thereby further improving the fixation of the gastric tube and further increasing the force required to pull out the gastric tube, thereby increasing the difficulty of pulling out the gastric tube, thereby preventing the gastric tube from being pulled out during the gastric lavage process, making it impossible to aspirate gastric fluid, and posing a safety hazard to the patient.

[0035] 3. The emergency gastric lavage nursing auxiliary equipment described in the present invention, when the piston ring moves to the left, the gas on the left side of the piston ring will be squeezed, the squeezed gas will enter the slide groove, and push the support rod to move to the side of the arc-shaped spring sheet, and squeeze the arc-shaped spring sheet. When the arc-shaped spring sheet is squeezed, it will push the rubber layer to fully fit the surface of the gastric tube. When the rubber layer and the gastric tube are fully fitted, the semicircular groove under the rubber layer can be better adsorbed on the gastric tube, thereby avoiding air leakage between the rubber layer and the gastric tube.

DETAILED DESCRIPTION

[0046] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0047] Embodiment 1: Figures 1 to 8 As shown, the emergency gastric lavage nursing auxiliary equipment of the present invention includes a gastric tube fixer; the gastric tube fixer includes an elliptical tube 1 and a circular ring 11;

[0048] The oval tube 1 is fixedly connected to the circular ring 11, and the oval tube 1 is used to be placed in the patient's mouth, and the gastric tube passes through the circular ring 11 and the oval tube 1; a bandage 12 is fixedly connected to the circular ring 11, and the bandage 12 is used to be tied to the patient's head;

[0049] The end surface of the circular ring 11 away from the elliptical tube 1 is fixedly connected to an annular plate 13, and the outer surface of the annular plate 13 is provided with threads;

[0050] A cylinder 2 is provided on the right side of the annular plate 13; a retaining ring 21 is fixedly connected to the outer surface of the cylinder 2 on the side of the cylinder 2 facing the annular plate 13;

[0051] A locking ring 22 is rotatably connected to the outer circumference of the cylinder 2, and the cross section of the locking ring 22 is L-shaped; a thread is provided on the inner circumference of the locking ring 22;

[0052] The blocking ring 21 is located inside the locking ring 22 and is used to block the locking ring 22; the locking ring 22 can be engaged on the annular plate 13 through threads;

[0053] The inner surface of the cylinder 2 is provided with two sets of limit assemblies; each set of the limit assemblies includes four arc-shaped spring pieces 23, and the arc-shaped spring pieces 23 are evenly arranged on the inner surface of the cylinder 2;

[0054] The two adjacent arc-shaped spring pieces 23 are spaced 90 degrees apart; each arc-shaped spring piece 23 is bent toward one side of the locking ring 22; and a rubber layer 24 is fixedly connected to the opposite end surface of each arc-shaped spring piece 23;

[0055] When inserting a stomach tube, the stomach tube is inserted from the side of the cylinder 2 away from the locking ring 22, and then the stomach tube passes through a plurality of arc-shaped spring sheets 23 and the rubber layer 24 in sequence. At the same time, the stomach tube squeezes the rubber layer 24 and the arc-shaped spring sheets 23 to bend to opposite sides, and the arc-shaped spring sheets 23, under the action of their own elastic force, push the rubber layer 24 against the surface of the stomach tube;

[0056] The outer surface of the cylinder 2 is provided with a reinforcement component, and the reinforcement component is used to improve the fixation degree of the gastric tube;

[0057] Specifically, when intubation is performed, the oval tube 1 is first placed in the patient's mouth, and then the bandage 12 is tied to the patient's head, and then the locking ring 22 is aligned with the annular plate 13, and the locking ring 22 is gradually rotated to gradually engage with the annular plate 13. When the locking ring 22 is fully engaged with the annular plate 13, the cylinder 2 is fitted with the ring 11, and then intubation can be performed;

[0058] More specifically, when intubation is performed, the gastric tube is inserted from the side of the cylinder 2 away from the oval tube 1, and the inserted gastric tube passes through the plurality of arc-shaped spring pieces 23 and the rubber layer 24 in sequence. When the gastric tube passes through the rubber layer 24, the gastric tube squeezes the rubber layer 24 and the arc-shaped spring pieces 23 to bend to the opposite side. At the same time, the arc-shaped spring pieces 23 push the rubber layer 24 against the surface of the gastric tube under the elastic force of themselves. During the process of the gastric tube being gradually extended, the gastric tube enters the oval tube 1, and then enters the patient's mouth, esophagus and stomach, and then the patient can be gastrically lavaged;

[0059] Furthermore, during the gradual intubation process, the arc-shaped spring piece 23 pushes the rubber layer 24 against the gastric tube under its own elastic force, and there is a certain friction between the rubber layer 24 and the gastric tube. If the gastric tube is pulled by an external force, the gastric tube itself has a tendency to move in the opposite direction. When the gastric tube moves in the opposite direction, under the action of the friction between the rubber layer 24 and the gastric tube, and the action of the arc-shaped spring piece 23 wanting to restore the initial state, the gastric tube will pull the rubber layer 24 and the arc-shaped spring piece 23 closer to each other. The rubber layers 24 approaching each other can resist the gastric tube, thereby limiting the continued movement of the gastric tube in the opposite direction, thereby increasing the force required to pull out the gastric tube, thereby increasing the difficulty of pulling out the gastric tube, and preventing the gastric tube from being easily pulled out. At the same time, when the patient is undergoing gastric lavage, the arc-shaped spring piece 23 and the rubber layer 24 can still resist and limit the gastric tube, thereby preventing the patient from being pulled out by external force during gastric lavage.

[0060] Furthermore, when gastric lavage is completed, the locking ring 22 is rotated in the opposite direction and gradually separated from the annular plate 13. When the locking ring 22 is completely separated from the annular plate 13, the locking ring 22 is held and the gastric tube is slowly pulled out of the patient's stomach. When the gastric tube is taken out of the mouth, the bandage 12 is loosened and the oval tube 1 is taken out of the patient's mouth.

[0061] By setting a limit assembly, the arc-shaped spring piece 23 and the rubber layer 24 on the limit assembly can be against the gastric tube. If the gastric tube is pulled by external force, the rubber layers 24 close to each other can hold the gastric tube, thereby limiting the gastric tube from continuing to move in the opposite direction, thereby increasing the force required to pull out the gastric tube, thereby increasing the difficulty of pulling out the gastric tube, thereby avoiding the need to reinsert the gastric tube after it is pulled out, and prolonging the emergency time of gastric lavage, thereby increasing the risk. If the gastric tube is subjected to too much external force, the limit assembly can reduce the length of the gastric tube being pulled out.

[0062] Embodiment 2: The reinforcement assembly includes an annular bin 3;

[0063] The outer ring surface of the cylinder 2 is fixedly connected with an annular chamber 3; a partition 31 is fixedly connected inside the annular chamber 3, and the partition 31 divides the annular chamber 3 into two chambers;

[0064] The two chambers are both slidably connected with piston rings 32; the piston ring 32 close to the locking ring 22 is fixedly connected with push rods 33 arranged evenly, and the push rods 33 pass through the partition plate 31 and the other piston ring 32 and extend out of the annular chamber 3;

[0065] The push rod 33 is slidably connected to the partition plate 31; the push rod 33 is also fixedly connected to the piston ring 32 on the other side; one side of the plurality of push rods 33 extending out of the annular chamber 3 is fixedly connected with a push ring 34;

[0066] Each rubber layer 24 is provided with an air tube 25; a semicircular groove 26 is provided at the bottom of each rubber layer 24, and the semicircular groove 26 is connected to the air tube 25;

[0067] Each of the air pipes 25 is provided with an air passage 27 on one side of the cylinder 2 facing the piston ring 32, and the air passage 27 is communicated with the space on the right side of the piston ring 32;

[0068] In this embodiment, the end surface of the annular bin 3 close to the push ring 34 is rotatably connected to the limit plate 35 via a rotating shaft. When the push ring 34 is pushed to fit with the annular bin 3, the limit plate 35 is rotated to fit with the push ring 34 to limit the push ring 34.

[0069] Specifically, when the intubation is completed, the push ring 34 is manually pushed to move toward one side of the annular chamber 3, and the push ring 34 pushes the piston ring 32 to move to the left through the push rod 33. During the movement of the piston ring 32 to the left, the gas in the airway 27 and the trachea 25 is sucked. Since the rubber layer 24 fits the gastric tube, when the gas in the trachea 25 is sucked out, the semicircular groove 26 opened on the rubber layer 24 is adsorbed on the gastric tube, thereby improving the fixation of the gastric tube.

[0070] More specifically, when the push ring 34 is fitted with the annular chamber 3, the limit plate 35 is rotated, and the rotating limit plate 35 limits the push ring 34 between the limit plate 35 and the annular chamber 3, so that the push ring 34 can be fixed to prevent the piston ring 32 from returning to its original state under the action of air pressure;

[0071] By extracting the gas in the trachea 25 and the airway 27, the rubber layer 24 can be adsorbed on the gastric tube, thereby further improving the fixation of the gastric tube and further increasing the force required to pull out the gastric tube, thereby increasing the difficulty of pulling out the gastric tube, thereby preventing the gastric tube from being pulled out during gastric lavage, making it impossible to aspirate gastric fluid, and posing a safety hazard to the patient.

[0072] Embodiment 3: A slide groove 4 is provided on the inner wall of the cylinder 2 on the left side of each of the air passages 27, and the slide groove 4 is connected to the space on the left side of the piston ring 32;

[0073] Each of the slide grooves 4 is slidably connected with a push rod 41, and the push rod 41 initially extends into the cylinder 2 and fits with the arc-shaped spring sheet 23;

[0074] In this embodiment, the four rubber layers 24 on the two limit assemblies are fixedly connected with an annular sleeve 43 on one side facing the locking ring 22;

[0075] The opening diameter of the annular sleeve 43 on the side close to the rubber layer 24 is larger than the opening diameter on the side away from the rubber layer 24;

[0076] In this embodiment, a curved plate 42 is fixedly connected to one side of each of the push rods 41 close to the curved spring piece 23; the curved plate 42 is in contact with the surface of the corresponding curved spring piece 23;

[0077] In this embodiment, a plurality of the arc-shaped plates 42 are close to each other and fit together to form a circular plate, so that the gastric tube can be limited by pushing the arc-shaped spring sheet 23 and the rubber layer 24, and the gastric tube can be prevented from being flattened;

[0078] Specifically, when the piston ring 32 moves to the left, the gas on the left side of the piston ring 32 will be squeezed, and the squeezed gas will enter the slide groove 4, and push the push rod 41 to move to the side of the arc-shaped spring sheet 23, and squeeze the arc-shaped spring sheet 23. When the arc-shaped spring sheet 23 is squeezed, it will push the rubber layer 24 to fully fit the surface of the gastric tube. When the rubber layer 24 is fully fitted with the gastric tube, the semicircular groove 26 under the rubber layer 24 can be better adsorbed on the gastric tube, thereby avoiding leakage between the rubber layer 24 and the gastric tube;

[0079] More specifically, since the supporting rods 41 are all fixedly connected with the arc-shaped plates 42, when the supporting rods 41 move toward the arc-shaped spring sheet 23, the arc-shaped plates 42 can be fully pressed against the arc-shaped spring sheet 23, so that the rubber layer 24 can be more fully in contact with the gastric tube. At the same time, since adjacent arc-shaped plates 42 are attached to form a circular plate, when adjacent arc-shaped plates 42 are attached to each other, the gastric tube can be limited in the multiple rubber layers 24. Moreover, due to the mutual obstruction between the multiple arc-shaped plates 42, the arc-shaped plates 42 can be prevented from continuing to push the arc-shaped spring sheet 23 to squeeze the gastric tube, thereby flattening the gastric tube.

[0080] Furthermore, since the opening diameter of the annular sleeve 43 close to the rubber layer 24 is larger than the opening diameter of the side away from the rubber layer 24, when the gastric tube is inserted, the annular sleeve 43 can guide the gastric tube, thereby preventing the gastric tube from extending downward in the cylinder 2 and thus being unable to pass through the multiple arc-shaped spring pieces 23.

[0081] Embodiment 4: Two extrusion plates 5 are provided on the right side of the push ring 34 on the cylinder 2; the extrusion plate 5 located at the bottom is fixedly connected to the cylinder 2 through a fixing rod;

[0082] A threaded rod 51 is rotatably connected to the extrusion plate 5 located above, and the threaded rod 51 passes through the cylinder 2 and extends to the top of the cylinder 2; the threaded rod 51 passes through one side of the cylinder 2 and is threadedly engaged with the cylinder 2;

[0083] Specifically, when it is necessary to control the on and off of the gastric tube, the threaded rod 51 is rotated, and the rotating threaded rod 51 will gradually extend into the cylinder 2 and gradually squeeze the upper squeezing plate 5, so that the upper squeezing plate 5 gradually squeezes the gastric tube and gradually approaches the lower squeezing plate 5. When the gastric tube is flattened, the liquid in the gastric tube no longer flows. When the gastric tube needs to be restored, the threaded rod 51 is rotated in the opposite direction, which will drive the upper squeezing plate 5 to move upward and gradually away from the lower squeezing plate 5, so that the gastric tube can be restored.
