Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a gastric lavage device for preventing accidental aspiration of acutely poisoned patients. Background Art

[0002] Gastric lavage is a medical procedure involving the insertion of a tube into the stomach, followed by the injection of fluids and suction to remove toxic substances or residual material from the stomach. When treating patients with acute poisoning, gastric lavage is used to remove toxic substances or residual material from the stomach, thereby reducing the spread of toxins.

[0003] Currently, when performing gastric lavage on a patient, when injecting liquid into the stomach, the injected liquid will be sucked out because it will be above the stomach. Moreover, when the speed of liquid injected into the stomach is greater than the speed of liquid sucked out of the stomach, it is easy to cause the pressure in the stomach to increase, so that the liquid, toxic substances and retained materials in the stomach can flow back from the gastric tube into the trachea, causing aspiration, and finally causing aspiration pneumonia and severe pneumonia, which aggravates the patient's condition. Summary of the Invention

[0004] The purpose of the present invention is to provide a gastric lavage device for preventing aspiration of patients with acute poisoning, so as to solve the problem raised in the above-mentioned background technology that when performing gastric lavage on a patient, when the speed of liquid injected into the stomach is greater than the speed of liquid sucked out of the stomach, it is easy to cause the pressure in the stomach to increase, thereby causing the liquid, toxic substances and retained materials in the stomach to flow back from the gastric tube into the trachea, causing aspiration, and finally causing aspiration pneumonia and severe pneumonia, which aggravates the patient's condition.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a gastric lavage device for preventing accidental aspiration of patients with acute poisoning, comprising:

[0007] A gastric tube assembly, comprising a catheter, a liquid inlet tube, a liquid outlet tube, and a partition, wherein the liquid inlet tube is connected to one side of the upper end of the catheter, the liquid outlet tube is connected to the other side of the upper end of the catheter, and the partition is fixedly connected to the central position inside the catheter;

[0008] A movable component, the movable component includes a liquid inlet, a liquid outlet, a first baffle ring, a second baffle ring, a cavity, a movable plate, a support plate, a first sealing block and a second sealing block. The liquid inlet is opened at one side of the lower end of the catheter, and the liquid outlet is opened at the other side of the lower end of the catheter. The first baffle ring is fixedly connected to the side of the lower end of the catheter close to the liquid inlet, and the second baffle ring is fixedly connected to the side of the lower end of the catheter close to the liquid outlet. The cavity is opened inside the lower end of the partition, the movable plate is slidably connected to the inside of the cavity, and the support plate is fixedly connected to both sides of the center of the movable plate. The first sealing block is fixedly connected to the upper end of one side of the support plate, and the second sealing block is fixedly connected to the lower end of one side of the support plate.

[0009] Furthermore, the liquid inlet is located above the liquid outlet, the first baffle ring is located at the lower end of the liquid inlet, and the second baffle ring is located at the upper end of the liquid outlet.

[0010] Furthermore, the first sealing block is located below the first retaining ring, and the second sealing block is located above the second retaining ring.

[0011] Furthermore, both ends of the movable plate are located inside the cavity, and the first sealing block and the second sealing block are used to seal the inside of the first retaining ring and the second retaining ring respectively.

[0012] Furthermore, it also includes a blocking component, which includes a sink, a first through hole, a support tube, a second through hole, an airbag, a hollow groove, an air inlet pipe and an air outlet pipe. The sink is opened on the outer surface of the upper end of the catheter, the first through hole is opened on one side of the sink, the support tube is fixedly connected to the outer surface of the sink, the second through hole is opened on one side of the support tube, the airbag is fixedly connected to the outer surface of the support tube, the hollow groove is opened on both sides of the inside of the partition, the air inlet pipe is fixedly connected to one side of the top end of the catheter, and the air outlet pipe is fixedly connected to the other side of the top end of the catheter.

[0013] Furthermore, the support tube is a rigid structure, and when the airbag is not filled with gas, the outer side surface is flush with the outer side surface of the catheter.

[0014] Furthermore, the first through hole and the second through hole are connected, and the hollow groove is respectively connected to the first through hole, the air inlet pipe and the air outlet pipe.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. The present invention provides a movable component. When the catheter is inserted into the stomach, if there is less liquid in the stomach, the liquid will not push the first sealing block to rise. The first sealing block moves downward under the impact of the liquid and drives the support plate and the movable plate to move downward, so that the second sealing block blocks the lower part of the liquid outlet, so that the liquid in the stomach cannot be discharged from the liquid outlet, and the liquid entering the stomach can be prevented from being directly sucked out. At the same time, when liquid is injected into the stomach, in order to avoid excessive injection and backflow of liquid in the stomach, the large amount of liquid in the stomach will push the support plate to move upward, and the support plate drives the first sealing block to move upward, so that the first sealing block blocks the upper end of the liquid inlet, so that the liquid cannot be injected into the stomach from the liquid inlet, and aspiration caused by excessive injection of liquid can be effectively prevented.

[0017] 2. Based on beneficial effect 1, by setting up a blocking component, by injecting gas from the air inlet pipe and closing the air outlet pipe, the gas is injected into the airbag from the inside of the hollow groove through the first through hole and the second through hole, causing the airbag to expand. The expansion of the airbag seals the inside of the gastric tube, so that when the stomach cramps, the liquid in the stomach will not be blocked by the airbag and will not flow from the gastric tube into the trachea, further avoiding aspiration.

[0028] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] See also Figure 1-3 As shown, this embodiment is a gastric lavage device for preventing accidental aspiration of patients with acute poisoning, comprising:

[0031] A gastric tube assembly, comprising a catheter 11, a liquid inlet tube 12, a liquid outlet tube 13, and a partition 14. The liquid inlet tube 12 is connected to one side of the upper end of the catheter 11, the liquid outlet tube 13 is connected to the other side of the upper end of the catheter 11, and the partition 14 is fixedly connected to the central position inside the catheter 11;

[0032] The movable assembly includes a liquid inlet 21, a liquid outlet 22, a first baffle ring 23, a second baffle ring 24, a cavity 25, a movable plate 26, a support plate 27, a first sealing block 28 and a second sealing block 29. The liquid inlet 21 is opened at one side of the lower end of the conduit 11, and the liquid outlet 22 is opened at the other side of the lower end of the conduit 11. The first baffle ring 23 is fixedly connected to the side of the lower end of the conduit 11 near the liquid inlet 21, and the second baffle ring 24 is fixedly connected to the side of the lower end of the conduit 11 near the liquid outlet 22. The cavity 25 is opened inside the lower end of the partition 14, the movable plate 26 is slidably connected to the inside of the cavity 25, the support plate 27 is fixedly connected to both sides of the center of the movable plate 26, the first sealing block 28 is fixedly connected to the upper end of one side of the support plate 27, and the second sealing block 29 is fixedly connected to the lower end of one side of the support plate 27;

[0033] The liquid inlet 21 is used to inject the liquid in the catheter 11 into the stomach, the liquid outlet 22 is used to suck the liquid in the stomach outward, the first baffle ring 23 is used to limit the first sealing block 28, the second baffle ring 24 is used to limit the second sealing block 29, the cavity 25 is used to place the movable plate 26, the movable plate 26 is used to support the support plate 27, and the support plate 27 is used to support the first sealing block 28 and the second sealing block 29 respectively. The liquid inlet pipe 12 is used to input the gastric lavage liquid into the inside of the catheter 11, and the liquid outlet pipe 13 is used to discharge the liquid in the catheter 11 outward.

[0034] The liquid inlet 21 is located above the liquid outlet 22, and the first baffle ring 23 is located at the lower end of the liquid inlet 21, and the second baffle ring 24 is located at the upper end of the liquid outlet 22;

[0035] The liquid inlet 21 and the liquid outlet 22 are respectively located at both ends of the stomach so that the injected liquid will not be directly sucked out.

[0036] The first sealing block 28 is located below the first retaining ring 23 , and the second sealing block 29 is located above the second retaining ring 24 ;

[0037] When the first sealing block 28 seals the first baffle ring 23 , liquid will not enter the stomach from the liquid inlet 21 . When the second sealing block 29 seals the second baffle ring 24 , liquid will not enter the inside of the catheter 11 from the liquid outlet 22 .

[0038] Both ends of the movable plate 26 are located inside the cavity 25, and the first sealing block 28 and the second sealing block 29 are used to seal the inside of the first retaining ring 23 and the second retaining ring 24 respectively;

[0039] The movable plate 26 can slide inside the cavity 25 .

[0040] Working principle: When the catheter 11 is inserted into the stomach, when there is less liquid in the stomach, the liquid will not contact the first sealing block 28 and thus cannot drive the first sealing block 28 to move upward. At this time, when liquid is injected into the stomach, the liquid flows downward from the inside of the catheter 11 and impacts the first sealing block 28, causing the first sealing block 28 to move downward along the inside of the catheter 11 and drive the support plate 27 and the movable plate 26 to move downward. The downward movement of the movable plate 26 drives the second sealing block 29 to move downward. The second sealing block 29 moves downward to the position of the second baffle ring 24 and is located above the liquid outlet 22, blocking the bottom of the liquid outlet 22, so that the liquid in the stomach cannot be discharged from the liquid outlet 22, which can prevent the liquid for gastric lavage just injected into the stomach from being directly sucked out, thereby failing to achieve the purpose of gastric lavage. When injecting liquid, in order to avoid excessive injection and resulting backflow of liquid in the stomach, when there is more liquid in the stomach, the support plate 27 will be pushed to move upward, and the support plate 27 will drive the first sealing block 28 and the movable plate 26 to move upward. At this time, when the first sealing block 28 moves to the position of the first baffle ring 23, the first sealing block 28 blocks the upper end of the liquid inlet 21, so that the liquid cannot continue to be injected into the stomach from the liquid inlet 21. At the same time, the movable plate 26 moves upward to cause the support plate 27 to drive the second sealing block 29 to move upward, so that the second sealing block 29 moves upward from the upper end of the second baffle ring 24, without blocking the position of the liquid outlet 22, so that the liquid in the stomach can enter the inside of the catheter 11 from the liquid outlet 22 and be discharged outward, which can effectively prevent aspiration caused by excessive backflow of liquid into the trachea due to the injection of too much liquid into the stomach.

[0041] Example 2

[0042] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0043] The blocking assembly includes a sink 31, a first through hole 32, a support tube 33, a second through hole 34, an airbag 35, a hollow groove 36, an air inlet pipe 37 and an air outlet pipe 38. The sink 31 is provided on the outer surface of the upper end of the conduit 11, the first through hole 32 is provided on one side of the sink 31, the support tube 33 is fixedly connected to the outer surface of the sink 31, the second through hole 34 is provided on one side of the support tube 33, the airbag 35 is fixedly connected to the outer surface of the support tube 33, the hollow groove 36 is provided on both sides of the interior of the partition 14, the air inlet pipe 37 is fixedly connected to one side of the top end of the conduit 11, and the air outlet pipe 38 is fixedly connected to the other side of the top end of the conduit 11;

[0044] The sink 31 is used to place the support tube 33, and the support tube 33 is used to support and block the air bag 35, and the air bag 35 is used to expand to block the gastric tube.

[0045] The support tube 33 is a rigid structure, and when the air bag 35 is not filled with gas, the outer surface thereof is flush with the outer surface of the catheter 11;

[0046] When the airbag 35 is inflated, the support tube 33 is a rigid structure, so that the airbag 35 will not cause the support tube 33 to deform. At the same time, the rigid structure of the support tube 33 will not affect the insertion of the catheter 11 into the stomach.

[0047] The first through hole 32 is connected to the second through hole 34, and the hollow groove 36 is connected to the first through hole 32, the air inlet pipe 37 and the air outlet pipe 38 respectively;

[0048] Gas can enter the hollow groove 36 from the air inlet pipe 37 and be discharged into the airbag 35 through the first through hole 32 and the second through hole 34 .

[0049] Working principle: When the catheter 11 is inserted into the stomach, gas is injected from the air inlet tube 37 and the air outlet tube 38 is closed, so that the gas is injected from the inside of the hollow groove 36 through the first through hole 32 and the second through hole 34 into the air bag 35, causing the air bag 35 to expand. The expansion of the air bag 35 seals the inside of the gastric tube, so that when the stomach spasms, the liquid in the stomach will be blocked by the air bag 35 and will not flow from the gastric tube into the trachea, further avoiding aspiration.
