Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a gastric lavage device for clinical use in emergency departments. Background Art

[0002] Gastric lavage is a crucial emergency procedure in clinical emergency care, often used to remove toxic substances, drug overdoses, or foreign objects from the stomach. Currently, the most widely used gastric lavage technique primarily involves periodic injection and withdrawal of fluids through a single gastric tube. While this technique achieves the purpose of gastric lavage to a certain extent, it has significant limitations and shortcomings.

[0003] First, the use of a single gastric tube for periodic injection and withdrawal inevitably increases the risk of gastric lavage fluid reflux during the procedure. When the withdrawal pump is activated, if the intragastric pressure or pump suction is not properly controlled, the injected gastric lavage fluid may flow back into the esophagus or mouth, not only affecting the gastric lavage effect but also causing additional pain and the risk of complications for the patient.

[0004] Secondly, the cyclical nature of gastric lavage reduces its overall efficiency. Each transition between injection and extraction requires a certain amount of time to ensure the lavage fluid is fully mixed with or diluted by the gastric contents. This inadvertently prolongs gastric lavage time, increasing the patient's treatment cycle and the consumption of medical resources.

[0005] How to invent a gastric lavage device for clinical use in the emergency department to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In order to make up for the above shortcomings, the utility model provides a gastric lavage device for clinical use in the emergency department, which aims to improve the problem of relatively low gastric lavage efficiency and increased reflux caused by periodic injection and extraction of liquid through a single gastric tube connected to a gastric lavage machine.

[0007] The utility model is implemented as follows: a gastric lavage device for clinical use in an emergency department comprises a gastric lavage machine body and a gastric tube, the gastric tube comprises a liquid discharge hose and a liquid extraction hose, one end of the liquid discharge hose is closed, one end of the liquid extraction hose is located inside the liquid discharge hose and is connected to the closed end of the liquid discharge hose, an opening is provided on the surface of the closed end of the liquid discharge hose that is connected to one end of the liquid extraction hose, a cavity for liquid discharge is formed between the inner wall of the liquid discharge hose and the outer wall of the liquid extraction hose, the other end of the liquid extraction hose passes through the liquid discharge hose at the inner wall extension of one side of the liquid discharge hose, the other ends of the liquid discharge hose and the liquid extraction hose are both connected and provided with a threaded connection sleeve, and a plurality of groups of liquid discharge holes are provided on the outer wall of the pipe section of the liquid discharge hose near its closed end and are evenly distributed in an annular shape along its extending direction.

[0008] In a preferred technical solution of the present invention, the inner wall of each threaded connection sleeve is provided with a thread for connecting the liquid outlet pump and the liquid suction pump port of the gastric lavage machine body, and the outer wall of each threaded connection sleeve is provided with a label of different color.

[0009] In a preferred technical solution of the present invention, a plurality of groups of support columns are arranged in the liquid outlet cavity near the closed end of the liquid outlet hose, which are evenly distributed in a circular shape along the extension direction of the liquid outlet hose and the liquid extraction hose. The two ends of each of the support columns are respectively fixedly connected to the inner wall of the liquid outlet hose and the outer wall of the liquid extraction hose.

[0010] In a preferred technical solution of the present invention, the liquid outlet hose and the liquid extraction hose are integrally formed.

[0011] In a preferred technical solution of the present invention, the liquid outlet hose and the liquid extraction hose are both made of transparent materials.

[0012] In a preferred technical solution of the present invention, the edge of the closed end of the liquid outlet hose is rounded.

[0013] In a preferred technical solution of the present invention, each of the liquid outlet holes has an elliptical structure.

[0014] The beneficial effect of the present invention is that the gastric lavage device for clinical use in the emergency department obtained by the present invention through the above design, when in use, the split-design liquid outlet hose and liquid extraction hose, combined with the evenly distributed liquid outlet holes, can more effectively spray the gastric lavage fluid and extract the gastric contents at the same time, thereby improving the gastric lavage efficiency and avoiding the reflux of the gastric lavage fluid.

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a gastric lavage device for clinical use in an emergency department, comprising a gastric lavage machine body and a gastric tube, the gastric tube comprising a liquid discharge hose 1 and a liquid extraction hose 2, one end of the liquid discharge hose 1 being closed, one end of the liquid extraction hose 2 being located inside the liquid discharge hose 1 and connected to the closed end of the liquid discharge hose 1, a surface of the closed end of the liquid discharge hose 1 being provided with an opening communicated with one end of the liquid extraction hose 2, a cavity for liquid discharge being formed between the inner wall of the liquid discharge hose 1 and the outer wall of the liquid extraction hose 2, the other end of the liquid extraction hose 2 passing through the liquid discharge hose 1 at the inner wall extension of the other end of the liquid discharge hose 1, the other ends of the liquid discharge hose 1 and the liquid extraction hose 2 are both communicated with a threaded connection sleeve 3, and a plurality of groups of liquid discharge holes 101 uniformly distributed in an annular manner along the extension direction thereof are opened on the outer wall of the pipe section of the liquid discharge hose 1 near its closed end.

[0023] See also Figures 2 to 4 The inner wall of each threaded connection sleeve 3 is provided with a thread for connecting the liquid outlet pump and the liquid suction pump port of the gastric lavage machine body, and the outer wall of each threaded connection sleeve 3 is provided with a label 301 of different color.

[0024] The other ends of both the outlet hose 1 and the suction hose 2 are equipped with threaded connectors 3, whose inner walls are threaded to match the ports of the gastric lavage machine's outlet and suction pumps, ensuring a secure connection. Each threaded connector 3 is fitted with a color-coded label 301 on its outer wall, making it easy for medical staff to quickly distinguish between the inlet and outlet lines and reduce misuse.

[0025] Furthermore, a plurality of groups of support columns 201 are arranged in the liquid outlet cavity near the closed end of the liquid outlet hose 1, which are evenly distributed in a circular shape along the extension direction of the liquid outlet hose 1 and the liquid extraction hose 2. The two ends of each support column 201 are respectively fixedly connected to the inner wall of the liquid outlet hose 1 and the outer wall of the liquid extraction hose 2.

[0026] Several groups of support columns 201 are provided in the cavity between the liquid outlet hose 1 and the liquid extraction hose 2 to enhance the structural stability and prevent the hoses from being deformed.

[0027] Furthermore, the liquid outlet hose 1 and the liquid extraction hose 2 are integrally formed.

[0028] The integral molding of the liquid outlet hose 1 and the liquid extraction hose 2 can improve the sealing of the overall structure, avoid leakage at the joint between the liquid extraction hose 2 and the liquid outlet hose 1, and also make it easier to insert the entire device into the patient's stomach.

[0029] Furthermore, the liquid outlet hose 1 and the liquid extraction hose 2 are both made of transparent materials.

[0030] The liquid outlet hose 1 and the liquid extraction hose 2 are both made of transparent material, which is convenient for medical staff to visually observe the flow of gastric lavage fluid and adjust the operation in time.

[0031] Furthermore, the edge of one closed end of the liquid outlet hose 1 is rounded.

[0032] The edge of the closed end of the liquid discharge hose 1 adopts a rounded corner design to reduce irritation to the patient's esophagus and stomach and reduce the patient's discomfort.

[0033] Furthermore, each liquid outlet 101 has an elliptical structure.

[0034] The liquid outlet 101 is designed as an elliptical structure to better meet the spraying requirements of the gastric lavage liquid and improve the cleaning effect.

[0035] Working Principle: During the gastric lavage process, medical staff first securely connect the gastric lavage machine's outlet pump port and suction pump port to the outlet hose 1 and suction hose 2 via threaded connectors 3. Because each connector 3 is fitted with a colored label 301 on its outer wall, medical staff can quickly and accurately identify the outlet hoses, thus avoiding connection errors. The gastric lavage machine then activates the outlet pump, injecting gastric lavage fluid into the patient's stomach through the outlet hose 1. The evenly distributed outlet holes 101 on the outer wall of the tube section near the closed end of the outlet hose 1 allow the gastric lavage fluid to be sprayed evenly and finely into every corner of the stomach, enhancing the cleaning effect. Furthermore, the elliptical design of the outlet holes 101 further adapts to the spraying requirements of the gastric lavage fluid, ensuring sufficient coverage and penetration of the gastric lavage fluid. The gastric lavage machine then simultaneously activates the suction pump. The suction hose 2 begins operation, effectively extracting the stomach contents and the mixed gastric lavage fluid. Due to the design of the liquid discharge cavity formed between the liquid extraction hose 2 and the liquid discharge hose 1 and the support column 201 in the cavity, not only the stability of the structure is enhanced and the deformation or twisting of the hose during the extraction process is prevented, but also the smooth progress of the extraction process is ensured. During the entire gastric lavage process, the simultaneous injection and extraction of liquid greatly improves the efficiency of gastric lavage and reduces the patient's discomfort. At the same time, medical staff can visually observe the flow of gastric lavage fluid and the extraction status of gastric contents through the transparent liquid discharge hose 1 and liquid extraction hose 2. The design of this transparent material greatly improves the convenience and accuracy of monitoring, allowing medical staff to adjust the parameters or operating techniques of the gastric lavage machine in time according to actual conditions to ensure the smooth progress of the gastric lavage process. In addition, the rounded corner design of the closed edge of the liquid discharge hose 1 also reduces the irritation and discomfort to the patient's stomach, improving the patient's tolerance and comfort.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
