Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a gastric lavage device for gastroenterology. Background Technology

[0002] Gastroenterology is a tertiary clinical discipline that primarily studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. Gastroenterology involves a wide variety of diseases, a broad range of medical knowledge, and complex and delicate procedures. Gastric lavage is often used for patients with acute food poisoning or accidental ingestion of poisons. The general principle of gastric lavage is to perform it as early as possible; every second counts. The longer the delay, the more poison will be absorbed through the gastrointestinal tract, potentially endangering the patient's life. Therefore, we should perform gastric lavage on patients with food poisoning as soon as possible.

[0003] Based on the above findings of the inventors, the existing gastric lavage equipment has the following main shortcomings. For example, after the gastric lavage is completed, the filter bottle needs to be manually cleaned by medical staff to remove the mucus and dirt adhering to it, and the filter bottle needs to be disinfected before it can be used again. In addition, the gastric lavage equipment does not have extra filter screens in reserve. When multiple patients need to undergo gastric lavage, it is necessary to wait for the filter screens to be cleaned and disinfected before they can be used, which delays the treatment of the patients. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that after gastric lavage is performed on a patient, the filter bottle needs to be manually cleaned by medical staff to remove the mucus and dirt adhering to it, and the filter bottle needs to be disinfected before it can be reused. In addition, the gastric lavage equipment does not have a spare filter screen. When multiple patients need gastric lavage, they have to wait for the filter screen to be cleaned and disinfected before it can be used, which delays the treatment of patients. Therefore, this invention proposes a gastric lavage device for gastroenterology.

[0005] To address the above problems, the present invention provides a gastric lavage device for gastroenterology.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1: Please refer to Figures 1-11 The specific embodiments of the present invention are as follows: Its structure includes a main shell 1, with two filter bottles 2 at the front end of the main shell 1. The filter bottles 2 are connected to a compressor pump 11 via conduits 3, and the compressor pump 11 is connected to a liquid guide connector 4. A control panel 5 is located on the top outer side of the main shell 1. A cooling fan 12, aligned with the compressor pump 11, is installed at the rear end of the main shell 1. A control module 13 is also located at the rear end of the main shell 1. A cleaning integrated device 14 is installed at the bottom inner end of the main shell 1. The cleaning integrated device 14 includes a cleaning chamber 141, the front end of which is closed by a door 142. The bottom of the cleaning chamber 141 is equipped with a water basin 143, and a cleaning device 144 is located in the middle of the cleaning chamber 141. The bottom of the cleaning device 144 is connected to a high-pressure water pump 146 via a water pipe 1444, and the high-pressure water pump 146 is connected to a water tank 145. In use, the device is connected to a gastric tube and a catheter for aspirating gastric lavage fluid via a liquid guide connector 4. The gastric lavage fluid is poured into the patient's stomach for cleaning with the help of a compressor pump 11, and the cleaned gastric fluid is drawn out and filtered through a filter bottle 2. When the gastric lavage procedure is completed, the gastric fluid in the filter bottle 2 can be discharged and then cleaned again through the cleaning device 144.

[0033] The cleaning device 144 includes a support base 1441, which is rotatably mounted in a support frame 1442. The bottom front end of the support base 1441 is movably engaged with a limiting buckle 1443. The bottom of the support base 1441 is also connected to a water pipe 1444. Two cleaning structures 1445 are also clamped and installed at the upper end of the support base 1441. The rear end of the support base 1441 is provided with a fixing structure 1446 that is aligned with the cleaning structures 1445. In use, the limiting buckle 1443 is swung outward, allowing the support base 1441 to swing forward at the end of the support frame 1442. This facilitates the insertion of the filter bottle 2 upside down into the cleaning structure 1445. Then, the fixing structure 1446 clamps and supports the bottom of the filter bottle 2, allowing the cleaning structure 1445 to clean the mucus and dirt inside the filter bottle 2.

[0034] The support base 1441 has filter tanks a1 on both sides, and a support mesh layer a3 is installed inside the filter tanks a1. A transmission device a5 and a high-pressure nozzle a4 are installed in the support mesh layer a3. The high-pressure nozzle a4 is connected to a water pipe 1444. A drying device a2 is installed in the middle of the support base 1441. In use, water in the water tank 145 can be drawn by the high-pressure water pump 146 and sprayed out through the water pipe 1444 to the high-pressure nozzle a4. The high-pressure water flow, in conjunction with the cleaning structure 1445, cleans the inside of the filter bottle 2.

[0035] The transmission device a5 includes a bearing seat a51, which is fixedly installed in the middle of the support mesh layer a3. The bearing seat a51 is engaged with the rotating shaft a52, and the top of the rotating shaft a52 is provided with a locking block a53, which is engaged with the locking groove b3 in the locking block b2 at the bottom of the cleaning structure 1445. The bottom of the rotating shaft a52 is provided with a gear groove a54, which is connected to the servo motor a57 through a transmission gear a55. The servo motor a57 is fixedly installed on the inner side of the waterproof frame a56. In use, the locking groove b3 in the locking block b2 at the bottom of the cleaning structure 1445 is inserted into the locking groove b3 in the bearing seat a51 for installation. Then, the servo motor a57 drives the rotating shaft a52 to rotate through the transmission gear a55, thereby driving the cleaning structure 1445 to rotate and brush the inside of the filter bottle 2.

[0036] The cleaning structure 1445 includes a support rod b1, with a crossbar b4 on the end face of the support rod b1. There are eight crossbars b4, arranged in groups of four at the upper and lower ends of the support rod b1. A stainless steel support strip b5 is fixedly connected to the end face of the crossbar b4. A sponge strip b6 is provided on the end face of the support strip b5, and the support strip b5 is in a cross shape. In use, when the filter bottle 2 is inserted upside down into the cleaning structure 1445, the inside of the filter bottle 2 will compress the support strip b5 and deform it, allowing the end face of the sponge strip b6 to fit tightly against the inside of the filter bottle 2. This increases the friction between the sponge strip b6 and the inside of the filter bottle 2, effectively cleaning the dirt inside the filter bottle 2.

[0037] The fixing structure 1446 includes a vertical rod c1 and a fixing cover c2. The vertical rod c1 is rotatably connected to the fixing cover c2 via a rotating rod c3. A return spring c4 is installed on the end face of the rotating rod c3, which can drive the fixing cover c2 to flip downwards. The downward flipping of the fixing cover c2 can be limited by the vertical rod c1. At the same time, when the vertical rod c1 limits the fixing cover c2, the fixing cover c2 and the support base 1441 are parallel to each other. The fixing cover c2 is movably engaged with the adjusting structure c5. Four... The clamping strip c6 is made of rubber, and the end face of the clamping strip c6 is provided with a protrusion c7. The adjusting structure c5 is movably engaged with the clamping strip c6. In use, the fixing cover c2 is flipped down and inserted into the bottom outside of the filter bottle 2. Then, by rotating the adjusting structure c5, the end face of the clamping strip c6 is pressed against the outside of the filter bottle 2 to clamp it. The protrusion c7 on the outside of the clamping strip c6 can increase the friction between the clamping strip c6 and the filter bottle 2, stably clamping the end face of the filter bottle 2 and assisting the filter bottle 2 in cleaning.

[0038] The adjustment structure c5 includes a turntable c51 that is snapped into the inside of the fixed cover c2, and four top blocks c52 are equidistantly arranged on the side end of the turntable c51. The top blocks c52 are movably engaged with the clamping strip c6, and the width of the top blocks c52 gradually narrows from the near end to the far end. In use, rotating the turntable c51 drives the top blocks c52 to press against the clamping strip c6 to clamp and fix the filter bottle 2.

[0039] Based on the above embodiments, the specific working principle is as follows: When gastric lavage equipment is used to perform gastric lavage on a patient, the fluid inlet connector 4 can be connected to the gastric tube and the catheter for aspirating gastric lavage fluid respectively. With the help of the compressor pump 11, the gastric lavage fluid is poured into the patient's stomach for cleaning, and the cleaned gastric fluid is drawn out and filtered through the filter bottle 2. When the gastric lavage is completed, the gastric fluid in the filter bottle 2 can be exported and then cleaned through the cleaning device 144. When multiple patients need to undergo gastric lavage, the two filter bottles 2 that have been cleaned in the cleaning device 144 can be removed for use, and the two filter bottles 2 that need to be cleaned can be placed in the cleaning device 144 for cleaning, so that they can be used next time. When cleaning the filter bottle 2, the limiting buckle 1443 is swung outward, allowing the support base 1441 to swing forward at the end of the support frame 1442, so that the filter bottle 2 is inserted upside down into the cleaning structure 1445. The support base 1441 is then reset and fixed by the limiting buckle 1443. Then, the fixing cover c2 is flipped down and inserted into the bottom outside of the filter bottle 2. The adjusting structure c5 is rotated to press against the end of the clamping bar c6 to clamp the outside of the filter bottle 2. The protrusion c7 on the outside of the clamping bar c6 increases the friction between the clamping bar c6 and the filter bottle 2, thus stably clamping the end face of the filter bottle 2. The slot b3 in the bottom locking block b2 of the cleaning structure 1445 is inserted into the slot b3 in the bearing seat a51 for installation. Then, the servo motor a57 drives the rotating shaft a52 to rotate through the transmission gear a55, thereby driving the cleaning structure 1445 to rotate and clean the mucus and dirt inside the filter bottle 2. When the filter bottle 2 is inserted upside down into the cleaning structure 1445, the inside of the filter bottle 2 will compress the support strip b5 and deform it, so that the end face of the sponge strip b6 can fit tightly against the inside of the filter bottle 2, which can increase the friction between the sponge strip b6 and the inside of the filter bottle 2, and thoroughly clean the dirt inside the filter bottle 2.

[0040] Example 2: Please refer to Figures 12-13 The specific embodiments of the present invention are as follows: The drying device a2 includes an air outlet structure a22 and an air outlet hood a23. The air outlet structure a22 is installed at the bottom of the support base 1441 via a support frame a21, and the air outlet structure a22 is connected to the interior of the air outlet hood a23 via an air guide pipe a24. Nine air outlet holes a25 are equally spaced on both sides of the air outlet hood a23, and the air outlet holes a25 are inclined to the side at a 45-degree angle. In use, the hot air generated by the operation of the air outlet structure a22 is transmitted to the air outlet hood a23 through the air guide pipe a24. The hot air is concentrated in the air outlet hood a23 and blown into the interior of the filter bottle 2 at an inclined angle through the air outlet holes a25 to dry the cleaned filter bottle 2.

[0041] The air outlet structure a22 includes a fan housing a221. The bottom of the housing a221 is provided with a fan a222, and the top of the inside of the fan housing a221 is provided with a heating wire a223. In use, the airflow generated by the operation of the fan a222 flows through the end face of the heating wire a223 to form hot air.

[0042] Based on the above embodiments, the specific working principle is as follows: When the cleaning of the filter bottle 2 is completed, the hot air generated by the air outlet structure a22 is transmitted to the air outlet hood a23 through the air guide pipe a24. The hot air is concentrated in the air outlet hood a23 and blown into the interior of the filter bottle 2 at an inclined angle through the air outlet hole a25 to dry the cleaned filter bottle 2. The cleaned and dried filter bottle 2 is stored in the cleaning chamber 141 and can be used as a spare filter bottle 2. It can be used for multiple patients who need gastric lavage surgery at the same time.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
