DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0023] Embodiment:

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 , an improved simple gastric lavage device, including a liquid injection container 1, a switch I 9 is installed on the outer wall of the gastric tube 5; a negative pressure absorption mechanism 10 is provided on the outer wall of the gastric tube 5, and the negative pressure absorption mechanism 10 includes a liquid suction pipe 101, a gastric juice collection box 102, two top pipes 103 and a negative pressure pipe 104; a switch II 11 is installed on the liquid suction pipe 101.

[0025] Among them, the liquid injection container 1 is made of transparent, high-temperature resistant, non-toxic medical-grade plastic material, which is convenient for observing the volume and color change of the gastric lavage fluid. According to the gastric lavage requirements of adults and children, liquid injection containers with different capacities are designed. For example, 5000 ml for adults and 2000 ml for children, to ensure that the gastric lavage task can be completed in one operation. And the liquid injection container 1 is a prior art, so it will not be described in detail here.

[0026] Among them, the gastric tube 5 is selected to be made of flexible tube material. This design fully takes into account the comfort of the patient and the operation convenience of the device. The flexible tube not only has good flexibility and bendability, can easily adapt to the complex path from the patient's oral cavity to the stomach, reduce the resistance and discomfort during intubation, but also ensures that the gastric lavage fluid can smoothly and accurately enter the patient's stomach, so as to achieve an effective gastric lavage effect.

[0027] Among them, the switch Ⅰ 9 is made of medical-grade plastic or silica gel material, ensuring non-toxic, non-irritating, and having good wear resistance and durability. The switch Ⅰ 9 serves as an additional safety locking mechanism. In case of emergency or when it is necessary to pause the gastric lavage, medical staff can quickly close the switch Ⅰ 9 to prevent the further inflow of the gastric lavage fluid, thus ensuring the safety of the patient. The existence of the switch Ⅰ 9 also plays a role in preventing misoperation. During the gastric lavage process, if medical staff need to leave temporarily or perform other operations, they can ensure the safety state of the gastric lavage device by closing the switch Ⅰ 9, avoiding the accidental injection of the gastric lavage fluid caused by accidental touch or other factors.

[0028] Among them, the negative pressure absorption mechanism 10 is used to extract the liquid in the patient's stomach under the action of negative pressure. One end of the liquid suction tube 101 is directly integrally connected to the outer wall of the gastric tube 5 to ensure that the liquid extracted from the patient's stomach can smoothly enter the negative pressure absorption system. The liquid suction tube 101 is made of soft and durable medical-grade material to adapt to the installation of the switch Ⅱ 11. The gastric juice collection box 102 serves as a container for storing the extracted gastric juice and gastric lavage waste liquid. Its surface is designed with two top tube 103 interfaces for connecting the liquid suction tube 101 and the negative pressure tube 104. The gastric juice collection box 102 is made of transparent material, which is convenient for medical staff to observe the volume and color change of the waste liquid. The top tube 103 serves as a connecting component. The two top tubes 103 are respectively flexibly inserted into the other end of the liquid suction tube 101 and the bottom end of the negative pressure tube 104 to ensure the sealing performance and connection stability between each component. The negative pressure tube 104 is connected to an external negative pressure source such as a negative pressure aspirator, and drives the liquid in the stomach to flow into the gastric juice collection box 102 through the liquid suction tube 101 by generating negative pressure. The design of the negative pressure tube 104 takes into account the requirements of easy connection and disassembly for cleaning and disinfection when needed.

[0029] Among them, the switch II 11 is also made of medical-grade plastic or silicone material to ensure that it is non-toxic, non-irritating, and has good abrasion resistance and durability. The installation of the switch II 11 provides another independent control point for the gastric lavage device. Medical staff can directly control the on-off state of the liquid suction tube 101 by operating the switch II 11, so as to achieve precise control of the gastric juice recovery process. This design enables medical staff to adjust the speed and amount of gastric juice recovery at any time according to the specific conditions of the patient and the effect of gastric lavage during the gastric lavage process. Similar to the switch I 9, the switch II 11 also plays a role in safety locking. In case of an emergency or when it is necessary to pause the gastric lavage, medical staff can quickly turn off the switch II 11 to prevent further recovery of gastric juice, thus ensuring the safety of the patient.

[0030] Please refer to Figure 1 、 Figure 2 、 Figure 3 , an improved simple gastric lavage device. The liquid outlet end of the liquid injection container 1 is integrally connected with a liquid inlet bladder 2. The side wall of the liquid inlet bladder 2 is provided with a branch pipe 3 by itself, and the bottom end is provided with a plugging head 4 by itself. The outer wall of the plugging head 4 is provided with a raised ring and is pluggingly connected with the inner top end of the gastric tube 5. The outer end of the branch pipe 3 is provided with a locking connection mechanism 6. A pressure pipe 7 is integrally installed on the locking connection mechanism 6. The inner top end of the pressure pipe 7 is threadedly connected with a pressure gauge 8; the locking connection mechanism 6 includes a female locking buckle 61 and a male locking buckle 62.

[0031] Among them, the liquid inlet bladder 2 is designed to be directly integrally connected to the liquid outlet end of the liquid injection container 1. This innovative measure significantly reduces the number of intermediate connection components, thus effectively reducing the leakage risk caused by numerous interfaces. At the same time, the liquid inlet bladder 2 also undertakes the important function of storing gastric lavage fluid midway, ensuring that the gastric lavage fluid maintains a stable pressure and flow rate before being delivered to the patient's stomach, further improving the reliability and safety of the gastric lavage operation.

[0032] Among them, the branch pipe 3 is led out from the side wall of the liquid inlet bladder 2 and is connected to the pressure display system through the locking connection mechanism 6.

[0033] Among them, the insertion fixing head 4 is designed to be directly integrally connected to the bottom end of the liquid inlet bladder 2. A groove ring matching the outer wall convex ring of the insertion fixing head 4 is designed at the inner top of the gastric tube 5. This design not only enhances the connection stability between the gastric tube 5 and the insertion fixing head 4, but also ensures the connection tightness and smoothness. The mutual flexible clamping mechanism between the groove ring and the convex ring enables the convex ring to smoothly slide into the groove ring when the insertion fixing head 4 is inserted into the gastric tube 5, and achieve a tight clamping when reaching the predetermined position. This clamping method not only avoids the possible loosening or falling off problems in the traditional connection method, but also reduces the leakage risk caused by loose connection. In addition, the flexible clamping design also takes into account the anatomical differences of the stomachs of different patients and the dynamic changes during the gastric lavage process. Even under the influence of physiological activities such as the patient's breathing and heartbeat, the connection between the gastric tube 5 and the insertion fixing head 4 can maintain sufficient stability and tightness, ensuring the smooth progress of the gastric lavage operation; making the disassembly of the gastric tube 5 more convenient.

[0034] Among them, the buckle connection mechanism 6 is made of medical-grade stainless steel material, which is strong and durable. The quick connection and disconnection of the branch pipe 3 and the pressure pipe 7 can be realized by rotating the buckle, and the operation is simple. One end of the female buckle 61 is integrally connected to the outer end of the branch pipe 3, and this design ensures the strength and tightness of the connection part, avoiding the leakage problem caused by loose connection. The other end of the female buckle 61 is designed with a locking structure matching the male buckle 62 to tightly connect the two together. One end of the male buckle 62 matches the locking structure of the female buckle 61, and a stable connection with the female buckle 61 is achieved through a specific locking mechanism. At the same time, the other end of the male buckle 62 is integrally connected to the bottom end of the pressure pipe 7, ensuring the stability and reliability of the pressure pipe 7 in the connection mechanism. When disassembly is required, only the locking structure needs to be gently unlocked. This design not only improves work efficiency, but also reduces the operation difficulty and error rate.

[0035] Among them, the integration of the pressure pipe 7 and the pressure gauge 8 is used to display the pressure value of the gastric lavage fluid entering the stomach in real time, ensuring the safety and controllability of the gastric lavage process. The pressure pipe 7, as a medium for transmitting pressure, accurately conducts the pressure generated by the pressure source to the pressure gauge 8, directly affecting the speed and force of the gastric lavage fluid entering the stomach. The closely integrated pressure gauge 8 can display the pressure value in this process in real time and accurately, providing an intuitive and reliable monitoring means for medical staff. By observing the reading of the pressure gauge 8 in real time, medical staff can quickly master the pressure state of the gastric lavage fluid in the patient's stomach, and thus make precise pressure adjustment according to the specific situation of the patient and the gastric lavage requirements. This instant feedback mechanism ensures the smooth progress of the gastric lavage process and effectively avoids complications or adverse reactions that may be caused by too high or too low pressure.

[0036] Working principle of the improved simple gastric lavage device: During gastric lavage, medical staff can flexibly use switch Ⅰ9 according to the specific conditions and gastric lavage requirements of the patient. Before the start of gastric lavage, medical staff can ensure that switch Ⅰ9 is in the open state and then confirm that switch Ⅱ11 is in the closed state; so that the gastric lavage solution can smoothly flow into the patient's stomach through the liquid injection bladder 2 and the gastric tube 5 under the action of the liquid injection container 1. During this process, medical staff can, through the pressure gauge 8, real-time observe the pressure state of the patient's stomach, effectively avoiding complications or adverse reactions that may be caused by too high or too low pressure. When extracting the patient's gastric juice, medical staff first ensure that switch Ⅰ9 is in the closed state and then confirm that switch Ⅱ11 is in the open state; then, turn on an external negative pressure source such as a negative pressure aspirator to generate negative pressure through the negative pressure tube 104. Under the action of the negative pressure, the liquid in the patient's stomach, including gastric juice and gastric lavage waste liquid, is sucked into the liquid suction tube 101 and flows through the gastric juice collection box 102 for storage.
