Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a gastric lavage device for acute poisoning patients. Background Art

[0002] Gastric lavage involves repeatedly injecting a specific liquid into the stomach, mixing it with the contents, and then withdrawing it. This procedure is intended to remove unabsorbed toxins from the stomach or to cleanse the stomach cavity. It is clinically used in preparation for gastric surgery and examinations. Gastric lavage is an important first-aid measure for acute poisoning, such as ingestion of organophosphorus, inorganic phosphate, alkaloids, or barbiturates within a short period of time.

[0003] When using gastric tube lavage clinically to perform gastric lavage on patients with acute poisoning, it is necessary to first insert the gastric tube into the stomach of the acute poisoning patient, use a syringe to draw out normal saline, then connect the nipple of the syringe to the inlet end of the gastric tube, push the syringe to inject normal saline into the stomach of the acute poisoning patient to lavage his stomach, and then use a syringe to extract the waste liquid in the stomach of the poisoned patient after the lavage is completed. However, in one lavage, a sufficient amount of normal saline needs to be injected into the stomach of the acute poisoning patient, generally 300-500ml, but the syringe commonly used in clinical practice is 50ml or 100ml. In the process of injecting normal saline into the stomach of the acute poisoning patient, it is necessary to use the syringe to aspirate the normal saline multiple times and connect and disassemble the nipple of the syringe to the inlet end of the gastric tube multiple times before a sufficient amount of normal saline can be injected into the stomach of the acute poisoning patient. During this process, the nipple of the syringe is easily contaminated, which can easily cause the normal saline injected into the stomach of the poisoning patient to be contaminated. In the process of extracting waste liquid from the stomach of the poisoning patient, it is necessary to connect and disassemble the nipple of the syringe to the inlet end of the gastric tube multiple times and use the syringe to aspirate the waste liquid multiple times before the waste liquid in the stomach of the poisoning patient can be sucked out clean. In this process, the nipple of the syringe will be contaminated by the waste liquid. After the nipple of the syringe is removed from the gastric tube, the nipple of the syringe is easily contaminated by the hands of medical staff. Utility Model Content

[0025] See also Figure 1-Figure 3 The utility model provides a technical solution: a gastric lavage device for patients with acute poisoning, comprising a container 1, a first connecting tube 2, a gastric tube 3, an air inlet 4 and an air extraction part 5, the container 1 is in a sealed state, one end of the first connecting tube 2 is connected to one end of the container 1, and the other end is connected to the inlet end of the gastric tube 3, the container 1 is used to hold physiological saline, the air inlet 4 is connected to the container 1, the air inlet 4 is used to supply air into the container 1 when the physiological saline in the container 1 is discharged, and the air extraction part 5 is connected to the one end of the container 1 and is used to suck out the air in the container 1.

[0026] The initial state of the gastric lavage device for acute poisoning patients of the present invention is that the container 1 is filled with physiological saline.

[0027] See also Figure 2When using the gastric lavage device for acute poisoning patients described in the present invention to inject normal saline into the stomach of the poisoned patient, the insertion end of the gastric tube 3 is first inserted into the stomach of the poisoned patient. The first connecting tube 2 is then connected to the one end of the container 1 so that the inner cavity of the first connecting tube 2 is connected to the container 1. The container 1 containing the normal saline is then lifted and raised above the inlet end of the gastric tube 3. The container 1 is then inverted so that the end of the container 1 connected to the air inlet 4 faces upward. The air inlet 4 is then opened to allow air to enter the container 1. When air enters the container 1, the normal saline in the container 1 flows downward under the action of gravity and is injected into the stomach of the poisoned patient through the first connecting tube 2 and the gastric tube 3. The container 1 used in this embodiment can hold more than 500 ml of normal saline, which is sufficient to meet the amount of normal saline required to be injected into the stomach of a poisoned patient using the gastric tube 3 gastric lavage method in clinical practice. After injecting the required amount of normal saline into the stomach of the poisoned patient, the air inlet 4 can be closed to prevent air from entering the container 1 through the air inlet 4. The remaining normal saline in the container 1 will not continue to flow into the stomach of the poisoned patient. At this time, the container 1 can be put down. With this structure, the gastric lavage device for acute poisoning patients described in the utility model can inject the required amount of normal saline into the stomach of the poisoned patient at one time. In addition, during the process of injecting normal saline into the stomach of the poisoned patient, the first connecting tube 2 does not need to be connected to and removed from the inlet end of the gastric tube 3 multiple times. During the process of injecting normal saline into the stomach of the poisoned patient using the gastric lavage device for acute poisoning patients described in the utility model, the possibility of contamination of the injected normal saline can be reduced.

[0028] See also Figure 3 When using the gastric lavage device for acute poisoning patients described in the present invention to extract waste liquid from the stomach of the poisoned patient, the air inlet portion 4 is closed, the end of the container 1 connected to the first connecting tube 2 is facing upward, and the container 1 is fixed on a work surface. The air extraction portion 5 is connected to the one end of the container 1, the air extraction portion 5 is connected to the container 1, and then the air in the container 1 is sucked out by the air extraction portion 5. After the air in the container 1 is sucked out by the air extraction portion 5, a negative pressure is formed in the container 1, so that the waste liquid in the stomach of the poisoned patient can be sucked out through the first connecting tube 2 and the gastric tube 3. The sucked waste liquid is collected in the container 1 through the gastric tube 3 and the first connecting tube 2. The capacity of the container 1 is sufficient to collect all the waste liquid in the stomach of the poisoned patient. With this structure, in the process of extracting waste liquid from the stomach of a poisoned patient, all the waste liquid is collected in the container 1, and the exhaust part 5 does not come into contact with the waste liquid. In the process of using the gastric lavage device for acute poisoning patients described in the utility model to extract waste liquid from the stomach of a poisoned patient, the possibility of medical staff's hands being contaminated by the waste liquid can be reduced.

[0029] In this embodiment, the air extraction part 5 includes a second connecting tube 501, a three-way tube 502, a third connecting tube 503, a second valve 504, a one-way valve 505 and a syringe 506. One end of the second connecting tube 501 is connected to the container 1, and the other end is connected to the first pipe mouth of the three-way tube 502. The inner cavity of the second connecting tube 501 is connected to the inner cavity of the container 1 and the inner cavity of the three-way tube 502. The second valve 504 is provided on the second connecting tube 501, one end of the third connecting tube 503 is connected to the second pipe mouth of the three-way tube 502, the one-way valve 505 is provided on the third pipe mouth of the three-way tube 502, the nipple of the syringe 506 is connected to the other end of the third connecting tube 503, and the inner cavity of the third connecting tube 503 is connected to the inner cavity of the three-way tube 502 and the inner cavity of the syringe 506.

[0030] See also Figure 3 In the process of using the gastric lavage device for acute poisoning patients of the present invention to extract the waste liquid in the stomach of the poisoned patient, the second valve 504 is opened, and then the piston handle of the syringe 506 is pulled. The one-way valve 505 provided on the third pipe opening of the three-way pipe 502 can only allow the air in the three-way pipe 502 to flow out to the outside, and the external air cannot pass through the one-way valve 505 to enter the three-way pipe 502. Therefore, when the piston handle of the syringe 506 is pulled, the syringe 506 can pump the container 1 The air in the container 1 is sucked out and flows into the syringe 506. When the syringe 506 sucks out the air in the container 1, a negative pressure is formed in the container 1, thereby extracting the waste liquid in the stomach of the poisoned patient through the first connecting tube 2 and the gastric tube 3 and collecting it in the container 1. After the piston handle of the syringe 506 is pulled to the farthest end, the second valve 504 is closed and the piston handle is pushed, so that the air in the syringe 506 can be discharged through the third connecting tube 503, the three-way tube 502 and the one-way valve 505. The above steps are repeated until all the waste liquid in the stomach of the poisoned patient is extracted and collected in the container 1. With this structure, the suction part 5 can suck out the air in the container 1, and then extract the waste liquid in the stomach of the poisoned patient and collect it in the container. During the process of extracting waste liquid from the stomach of a poisoned patient, all the waste liquid is collected in the container 1, the vacuum part 5 does not contact the waste liquid, and the syringe 506 does not need to be disassembled or connected multiple times, which can improve the efficiency of extracting waste liquid from the stomach of a poisoned patient.

[0031] In this embodiment, the container 1 includes a bottle body 101 and a stopper 102. The bottle body 101 has an opening at one end, and the stopper 102 is inserted and fixed in the opening of the bottle body 101. The one end of the first connecting tube 2 and the one end of the second connecting tube 501 are both connected to the stopper 102. With this structure, the stopper 102 can be removed from the bottle body 101, thereby opening the bottle mouth of the bottle body 101, making it convenient to inject a desired amount of physiological saline into the container 1.

[0032] In this embodiment, the bottle stopper 102 is made of rubber material, and the first connecting tube 2 is connected to the first puncture tube 6. One end of the first puncture tube 6 is fixedly connected to the first connecting tube 2, and the other end of the first puncture tube 6 passes through the bottle stopper 102 and is located within the bottle body 101. With this structure, the bottle stopper 102 made of rubber material is easy to puncture. The first puncture tube 6 punctures the bottle stopper 102 made of rubber material, thereby fixing the first connecting tube 2 to the bottle stopper 102, making it more convenient to connect the first connecting tube 2 to the container 1.

[0033] In this embodiment, the bottle stopper 102 is made of rubber material, and the air extraction unit 5 further includes a second puncture tube 7. One end of the second puncture tube 7 is fixedly connected to the second connecting tube 501, and the other end of the second puncture tube 7 passes through the bottle stopper 102 and is located within the bottle body 101. With this structure, the rubber bottle stopper 102 is easily punctured. Once the second puncture tube 7 punctures the rubber bottle stopper 102, the second connecting tube 501 can be connected to the bottle stopper 102, making it more convenient to connect the air extraction unit 5 to the container 1.

[0034] In this embodiment, the ends of the first puncture tube 6 and the second puncture tube 7 for connecting to the bottle stopper 102 are both sharp triangular prisms, making it easier to puncture the bottle stopper 102 with the first puncture tube 6 and the second puncture tube 7.

[0035] In this embodiment, the bottle body 101 is provided with scale lines 8. With this structure, when injecting saline into the stomach of a poisoned patient, the scale lines 8 can clearly indicate the amount of saline injected into the stomach of the poisoned patient.

[0036] In this embodiment, the air intake portion 4 includes an air intake pipe 401 and a first valve 402 . The air intake pipe 401 is connected to the bottle body 101 and communicates with the inner cavity of the bottle body 101 . The first valve 402 is provided on the air intake pipe 401 .

[0037] When using the gastric lavage device for acute poisoning patients of the present invention to inject physiological saline into the stomach of the poisoned patient, the first valve 402 is opened, and outside air can enter the container 1 through the air inlet pipe 401. The physiological saline in the container 1 can then flow downward under the action of gravity and be injected into the stomach of the poisoned patient through the first connecting tube 2 and the stomach tube 3. With this structure, the air inlet portion 4 can allow air to enter the container 1, so that the physiological saline in the container 1 can flow downward and be injected into the stomach of the poisoned patient through the first connecting tube 2 and the stomach tube 3.

[0038] When using the gastric lavage device for acute poisoning patients described in the present invention to extract waste liquid from the stomach of the poisoned patient, the first valve 402 is closed. When the suction unit 5 sucks out the air in the container 1, the outside air will not enter the container 1 through the air inlet pipe 401, so that the suction unit 5 can extract the air in the container 1 and form a negative pressure in the container 1, thereby achieving the purpose of extracting waste liquid from the stomach of the poisoned patient.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
