[0003] In the actual gastric lavage operation, the gastric lavage tube and the gastric lavage bucket work together. First, the nurse or doctor will select a suitable gastric lavage tube according to the clinical situation and insert it into the patient's stomach according to the sterile operating procedures. Then, gastric lavage fluid is infused into the stomach through the gastric lavage tube. After the gastric fluid is mixed with the gastric contents in the stomach, it is sucked back into the gastric lavage bucket through the side holes on the gastric lavage tube or the suction channel of the double-lumen gastric lavage tube. This process may be repeated many times until the discharged fluid becomes clear, indicating that the gastric contents have been effectively removed.

[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] The embodiment of the present application provides a novel gastric lavage tube and gastric lavage bucket device, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0041] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] Example 1

[0043] See also Figure 1-7In the embodiment, a novel gastric lavage tube and gastric lavage bucket device is provided, comprising: a gastric lavage bucket body 1, a fixing plate 101 is installed inside the gastric lavage bucket body 1, a water pump 2 and a negative pressure pump 201 are installed on the top of the fixing plate 101, a gastric lavage tube 202 is connected to the top of the water pump 2, a fixing block 5 with an annular structure is provided on the top of the gastric lavage bucket body 1, a fixing frame 4 with an annular shape is provided on the top of the fixing block 5, and the gastric lavage tube 202 passes through the fixing block 5 and the fixing frame 4; an extrusion component arranged inside the fixing block 5, used for extruding the gastric lavage tube 202; a clamping component arranged on the fixing frame 4, used for clamping and fixing the gastric lavage tube 202; and an adjustment component arranged between the gastric lavage bucket body 1 and the fixing frame 4, used for adjusting the height of the fixing frame 4.

[0044] Among them, through the setting of the temperature sensor 103 and the display screen 104, the temperature of the gastric lavage solution can be known in real time, so that medical personnel can use gastric lavage solution with appropriate temperature for gastric lavage operation and minimize the stimulation to the gastric mucosa; secondly, through the coordinated setting of the fixing component and the adjusting component, the gastric lavage tube 202 can be fixed at different heights to ensure that the position of the gastric lavage tube 202 is fixed, and pulling the gastric lavage tube 202 to cause the gastric lavage tube 202 to shift, slip or cause discomfort to the patient, thereby improving the applicability of the device; then, through the setting of the squeezing component, the perfusion flow of the gastric lavage solution inside the gastric lavage tube 202 can be changed to ensure that the perfusion speed is appropriate, and to avoid too fast perfusion, which may cause the gastric lavage solution to fail to fully contact the stomach wall and stomach contents, reduce the cleaning effect, and may also rapidly increase the intragastric pressure, induce or aggravate serious complications such as gastric dilatation, gastric torsion, and gastric perforation.

[0045] Among them, a partition 102 is connected to the bottom of the fixed plate 101, and the interior of the gastric lavage barrel body 1 is divided into a water storage chamber and a waste liquid chamber by the partition 102. The water storage chamber is loaded with gastric lavage fluid, which can be physiological saline, activated carbon suspension, alkaline solution (such as sodium bicarbonate solution) or acidic solution (such as citrate solution). A temperature sensor 103 is installed on one side of the partition 102, and a display screen 104 is installed on the surface of the gastric lavage barrel body 1. A water pump 2 is connected to the bottom of the water pump 2, and the water pump is extended to the bottom of the water storage chamber. A drain pipe is connected to the bottom of the negative pressure pump 201, and the drain pipe is connected to the waste liquid chamber. A negative pressure pipe 203 is connected to the top of the negative pressure pump 201, and one end of the negative pressure pipe 203 extends to the inside of the gastric lavage tube 202.

[0046] When performing gastric lavage on a patient, the temperature of the gastric lavage fluid in the water storage chamber is sensed by the temperature sensor 103, and the temperature data is transmitted to the display screen 104. The temperature of the gastric lavage fluid is displayed in real time on the display screen 104, so that medical personnel can use gastric lavage fluid with a suitable temperature for gastric lavage. It is usually recommended to use 37-40°C, which is close to human body temperature and can minimize the stimulation to the gastric mucosa. Too cold or too hot gastric lavage fluid may cause stomach discomfort, cramps or inflammatory reactions.

[0047] When performing gastric lavage, the gastric lavage liquid in the water storage chamber is pumped into the gastric lavage tube 202 through the water pump 2, and the gastric lavage liquid is perfused into the stomach through the gastric lavage tube 202. After the gastric lavage liquid is mixed with the gastric contents in the stomach, the negative pressure generated by the negative pressure pump 201 allows the mixture to be drawn back through the negative pressure tube 203 in the gastric lavage tube 202, and discharged into the waste liquid chamber through the drain pipe for temporary collection and storage;

[0048] The model of the temperature sensor 103 is a miniature PT100 temperature sensor P0.215.2L0500. This temperature sensor 103 has an ultra-small size and is easy to install. It can be used in an environment where a small gap requires precise installation. The temperature sensor 103 can be purchased directly from the market. The temperature sensor 103 is a mature conventional technology in this technical field, and this solution does not improve the circuit or program of the temperature sensor 103. The circuit connection method between the temperature sensor 201 and the display screen 104 also belongs to the public conventional technology, so the circuit and signal connection relationship will not be repeated.

[0049] Example 2

[0050] On the basis of Example 1, the adjustment component includes: an adjustment slot 3 opened inside the gastric lavage barrel body 1; an adjustment block 301 with an L-shaped structure arranged on the top of the gastric lavage barrel body 1, one end of the adjustment block 301 is connected to the fixing frame 4, and one end of the adjustment block 301 extends into the adjustment slot 3; a plurality of adjustment holes 302 opened on the adjustment block 301, and the plurality of adjustment holes 302 are evenly arranged in the vertical direction; a fixing hole 303 opened on one side of the gastric lavage barrel body 1, a fixing rod 304 matching with the fixing hole 303 is passed through the fixing hole 303, and one end of the fixing rod 304 passes through the adjustment hole 302.

[0051] During the gastric lavage process, the position of the gastric lavage tube 202 needs to be fixed to ensure that it maintains the correct position during the gastric lavage operation to prevent displacement, slippage or discomfort to the patient. Since the patient has different postures during the gastric lavage process, the middle of the gastric lavage tube 202 is prone to bend downward and fall between the patient and the gastric lavage barrel body 1, thereby pulling the gastric lavage tube 202. At this time, the position of the fixing frame 4 can be changed to adjust the height of the fixing frame 4 supporting the gastric lavage tube 202 to prevent the gastric lavage tube 202 from contacting the ground;

[0052] When adjusting the height of the fixing frame 4, the fixing rod 304 can be taken out from the fixing hole 303 to release the locking and fixing of the adjusting block 301, and then the adjusting block 301 can be pulled to move according to the required height to change the height of the fixing frame 4. After the adjustment is completed, the position of the fixing hole 303 corresponds to the position of the adjusting hole 302. At this time, the fixing rod 304 is re-through the fixing hole 303 and inserted into the adjusting hole 302 to complete the locking and fixing of the adjusting block 301, and the adjusting block 301 and the fixing frame 4 are fixed at the current position.

[0053] Example 3

[0054] On the basis of Example 1 and Example 2, the clamping assembly includes: a clamping groove 401 opened inside the fixing frame 4, a clamping block 403 with an arc-shaped structure is provided inside the clamping groove 401, and the clamping block 403 is made of rubber material; an opening 402 opened on one side of the fixing frame 4 and communicating with the clamping groove 401, and a clamping rod 404 is passed through the opening 402, one end of the clamping rod 404 extends to the inside of the clamping groove 401 and is connected to the clamping block 403; a pull plate 405 connected to one end of the clamping rod 404, a clamping spring 406 is connected to one side of the pull plate 405, the clamping spring 406 is connected to the outer side of the fixing frame 4, and the clamping spring 406 is sleeved on the outer side of the clamping rod 404.

[0055] After the position adjustment of the fixing frame 4 is completed, the pull plate 405 can be pulled so that the pull plate 405 can receive the clamping block 403 into the clamping groove 401 through the clamping rod 404, so that the gastric lavage tube 202 can pass through the middle of the fixing frame 4. After the gastric lavage tube 202 passes through the fixing frame 4 for a distance, the pull plate 405 is released. At this time, the pull plate 405 drives the clamping rod 404 and the clamping block 403 to rebound under the action of the elastic force of the clamping spring 406, so that the clamping block 403 clamps and fixes the gastric lavage tube 202, freeing the medical staff. The clamping block 403 is made of rubber material, so that there is a very high friction coefficient between the clamping block 403 and the gastric lavage tube 202, which ensures the fixing effect of the clamping block 403 and the gastric lavage tube 202. The clamping block 403 has an arc-shaped structure, so that the clamping block 403 can completely cling to the outside of the gastric lavage tube 202, increase the clamping area of ​​the gastric lavage tube 202, improve the fixing effect, and reduce the influence of the clamping force on the extrusion deformation of the gastric lavage tube 202.

[0056] Example 4

[0057] On the basis of Example 1, the extrusion assembly includes: a thread groove 501 in an annular structure opened on the upper surface of the fixed block 5, a rotating plate 503 is provided on the top of the fixed block 5; a thread block 502 connected to the bottom of the rotating plate 503; a plurality of extrusion grooves 504 opened inside the fixed block 5 and communicating with the thread groove 501, an extrusion block 505 is passed through the extrusion groove 504, one end of the extrusion block 505 is connected to the extrusion plate, and the other end of the extrusion block 505 extends into the thread groove 501 and is provided with an inclined surface.

[0058] Among them, the outer side of the threaded block 502 is provided with a thread that matches the threaded groove 501, the inner side of the bottom end of the threaded block 502 is provided with an inclined surface, the inside of the fixed block 5 is provided with a limiting groove 506 that communicates with the extrusion groove 504, and the bottom of the extrusion block 505 is connected to a limiting plate 507 that matches the limiting groove 506, and a limiting spring is provided between the limiting plate 507 and the limiting groove 506.

[0059] During the gastric lavage process, an appropriate gastric lavage fluid infusion speed can ensure that the gastric lavage fluid is fully mixed with the gastric substances and improve the removal efficiency of poisons or drugs. Too slow may lead to incomplete removal, while too fast may prevent the gastric lavage fluid from fully contacting the gastric wall and gastric contents, reducing the removal effect. It may also rapidly increase the intragastric pressure and induce or aggravate serious complications such as gastric dilatation, gastric torsion, and gastric perforation.

[0060] Therefore, during the operation, the squeezing block 505 can be used to squeeze the gastric lavage tube 202, thereby changing the cross-sectional shape of the lumen inside the gastric lavage tube 202, so that the gastric lavage solution is obstructed when passing through, the flow rate is reduced, and the perfusion flow rate of the gastric lavage solution is slowed down;

[0061] When the position of the extrusion block 505 is changed, the rotating plate 503 can be rotated to make the rotating plate 503 drive the threaded block 502 to rotate in the thread groove 501, so that the threaded block 502 moves downward under the action of the thread of the thread groove 501. At this time, the inclined surface on the inner side of the bottom end of the threaded block 502 contacts the inclined surface at the end of the extrusion block 505, and as the threaded block 502 gradually moves downward, the extrusion block 505 is squeezed into the extrusion groove 504, so that the other end of the extrusion block 505 drives the extrusion plate to squeeze the gastric lavage tube 202. During the movement of the extrusion block 505, the movement direction and distance of the extrusion block 505 can be limited by the setting of the limiting plate 507 and the limiting groove 506. Then, when it is necessary to release the extrusion of the gastric lavage tube 202, the rotating plate 503 can be rotated in the opposite direction to make the threaded block 502 move upward in the thread groove 501. At this time, the extrusion block 505 rebounds under the action of the elastic force of the limiting spring 508, thereby driving the extrusion plate away from the gastric lavage tube 202.
