Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a pressure-adjustable gastric lavage device. Background Technology

[0002] Gastric lavage involves injecting lavage fluid into the patient's stomach, mixing it with the contents of the stomach, and then withdrawing it to reduce the presence of toxins in the stomach. Existing gastric lavage devices mainly use automatic gastric lavage machines to perform the lavage. Automatic gastric lavage machines use an air pump to generate gas, providing positive and negative pressure to complete the process of injecting and aspirating water into the stomach. Pressure sensors monitor pressure changes in real time, and the pressure value on the control panel is used to adjust the injection and aspiration pressure of the automatic gastric lavage machine.

[0003] When performing gastric lavage on patients, existing automatic gastric lavage machines use an oral gag to open the patient's mouth and keep it open. The gastric lavage tube is then inserted into the patient's stomach through the mouth. Medical tape is used to fix the gastric lavage tube to the oral gag. The gastric lavage tube is then connected to the inlet of the automatic gastric lavage machine. After adjusting the water pressure through the control panel, the automatic gastric lavage operation begins.

[0004] After the gastric lavage tube is inserted into the patient's stomach, it is secured to the mouth opening device with tape. However, during the gastric lavage process, the patient's stomach will move, and the patient will unconsciously swallow due to the influence of the gastric lavage tube in the mouth, causing the gastric lavage tube to move. Staff need to adjust the position of the gastric lavage tube, but repeated operation can easily cause the tape to loosen, affecting the effect of gastric lavage.

[0005] Therefore, the present invention provides a pressure-adjustable gastric lavage device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: An adjustable pressure gastric lavage device of this invention includes a fixed base, a hanging plate, a housing, a cover plate, and a pressure plate. Hanging plates are fixedly connected to both sides of the vertical plate of the fixed base. The housing is installed on the inner top surface of the fixed base. Grooves are opened on both sides of the housing. A cover plate is fastened to the top surface of the housing. Pressure plates are fixedly connected to both sides of the bottom surface of the cover plate. The side wall of the pressure plate slides against the inner wall of the groove. A gastric lavage tube slides through the grooves on both sides. During operation, when the automatic gastric lavage machine performs gastric lavage on a patient, an opening device is used to open the patient's mouth and keep it open. The hanging plate is hung on the opening device, so that the fixed base is fixedly connected to the opening device. The housing is installed on the fixed base. The gastric lavage tube is placed inside the groove and then... The tube is inserted into the patient's stomach through the mouth. The cover plate is installed on the top of the casing, allowing the pressure plate to slide into the groove and clamp the tube in place. The tube is then connected to the inlet of the automatic gastric lavage machine. After adjusting the water pressure via the control panel, the automatic gastric lavage begins. When the patient's stomach moves due to peristalsis and the tube in the mouth causes involuntary swallowing, the cover plate is loosened again to loosen the clamping of the tube. Medical staff then adjust the position of the tube before fixing the cover plate back in place to lock the tube in place. This reduces the probability of the tube shifting due to reduced adhesion from repeated use of medical tape, improving the stability of the gastric lavage and reducing the need for tube repositioning.

[0008] Preferably, the inner bottom surface of the fixed base is provided with a sliding groove, and the bottom surface of the housing is fixedly connected to a slider. The outer wall of the slider slides in cooperation with the inner wall of the sliding groove. The cross-section of the sliding groove is convex. The slider matches the sliding groove. The end of the slider near the inside of the sliding groove and the inner wall of the sliding groove are both embedded with magnets. The magnets on both sides attract each other. During operation, after the fixed base is installed on the opening device, the slider at the bottom of the housing is slid into the inside of the sliding groove. The housing is fixed on the fixed base by the magnets on both sides. The housing is installed into the fixed base along the axial direction of the groove opening. This facilitates installation by medical personnel and also makes it easy for medical personnel to remove the housing before removing the gastric lavage tube, reducing the probability of gastric fluid contamination inside the housing when removing the gastric lavage tube.

[0009] Preferably, an oiling cavity is formed inside the side of the housing away from the fixed base. A square seat is installed inside the oiling cavity, and an installation hole is provided in the center of the square seat. A silicone ring seat is slidably installed inside the installation hole. Medical gauze is placed on the inner ring of the silicone ring seat. The medical gauze is soaked in medical paraffin oil. The axis of the installation hole is the same as the axis of the groove. When medical personnel insert the gastric lavage tube into the patient's stomach, in order to reduce damage to the patient's oral cavity, trachea, and gastric tube, medical personnel will apply medical paraffin oil to the outer wall of the gastric lavage tube. Existing application methods require medical personnel to use medical... Apply medical paraffin oil to gauze while inserting the tube. During the procedure, attach the gauze soaked in medical paraffin oil to the inner wall of the silicone ring seat, then install the silicone ring seat into the mounting hole of the square seat, and finally install the square seat into the oiling cavity. When inserting the tube, the medical staff passes the gastric lavage tube through the silicone ring seat, allowing the outer wall of the gastric lavage tube to slide against the medical gauze, thus applying the medical paraffin oil from the gauze to the outer wall of the gastric lavage tube. This allows the medical staff to focus solely on inserting the gastric lavage tube without needing to apply the medical paraffin oil, reducing the probability of operational errors.

[0010] Preferably, a fixing sleeve is fixedly connected to both sides of the bottom surface of the oiling cavity, and a fixing groove is formed on both sides of the inner wall of the fixing sleeve. A fixing post is fixedly connected to both sides of the bottom surface of the square base. The outer wall of the fixing post slides into the inner wall of the fixing sleeve. Multiple rubber protrusions are fixedly connected to the outer wall of the fixing post, and the rubber protrusions slide into the fixing grooves. During operation, when the square base is installed into the oiling cavity, the fixing post is inserted into the fixing sleeve, so that the rubber protrusions slide into the fixing grooves, fixing the fixing post inside the fixing sleeve. Since the rubber protrusions are elastic, it is easy for medical personnel to install and remove the fixing sleeve, and at the same time, the stability of the fixing sleeve is improved.

[0011] Preferably, the outer circumference of the silicone ring seat away from the fixed base is fixedly connected to multiple No. 1 guide strips, and the outer circumference of the mounting hole away from the fixed base is provided with multiple No. 1 guide grooves. The outer wall of the No. 1 guide strips slides in engagement with the inner wall of the No. 1 guide grooves. The outer circumference of the silicone ring seat near the fixed base is provided with multiple No. 2 guide grooves, and the outer circumference of the mounting hole near the fixed base is fixedly connected to multiple No. 2 guide strips. The outer wall of the No. 2 guide strips slides in engagement with the inner wall of the No. 2 guide grooves. During operation, when the silicone ring seat is installed into the mounting hole, the No. 1 guide strips slide into the No. 1 guide grooves, and the No. 2 guide strips slide into the No. 2 guide grooves. The sliding installation of the silicone ring seat facilitates disassembly, cleaning, and disinfection by medical personnel. At the same time, it controls the depth of the silicone ring seat installed into the mounting hole, reducing the probability of the silicone ring seat sliding out of the mounting hole when the gastric lavage tube is moved.

[0012] Preferably, the inner ring of the silicone ring seat has a groove in the middle, and a Velcro fastener is fixed inside the groove. The Velcro fastener is bonded to the medical gauze. By using the Velcro fastener fixed inside the groove, the medical gauze is firmly bonded to the Velcro, thus installing the medical gauze inside the groove. This reduces the probability of the medical gauze being pulled away from the inner ring of the silicone ring seat by the gastric lavage tube. At the same time, the Velcro fastener makes it easier for medical staff to change the medical gauze, improving the convenience of their work.

[0013] Preferably, the inner ring of the silicone ring seat is a tapered hole, and the inner ring diameter on the side of the silicone ring seat closer to the fixed base is smaller than the inner ring diameter on the side of the silicone ring seat farther from the fixed base. By setting the inner ring of the silicone ring seat to be tapered, not only can the silicone ring seat be adapted to different sizes of gastric lavage tubes, but the inner ring of the silicone ring seat will also exert a certain amount of pressure on the outer wall of the gastric lavage tube, scraping off excess medical paraffin oil from the outer wall of the gastric lavage tube.

[0014] Preferably, the housing has an adjustment cavity on the side near the fixed base, and through slots on both sides of the adjustment cavity. A guide rail is fixed to the bottom surface of the adjustment cavity, and a slide block is slidably installed on the outer side of the guide rail. Arc-shaped clamping arms are hinged to the top of the slide block on both sides. A torsion spring is provided on the outer ring of the rotating shaft of the arc-shaped clamping arm. A push rod is hinged to the side of the arc-shaped clamping arm near the through slot. The push rod passes through the through slot, and the outer wall of the push rod slides in cooperation with the inner wall of the through slot. During operation, when the position of the gastric lavage tube needs to be adjusted, the medical staff pushes the push rods on both sides into the adjustment cavity, so that the arc-shaped clamping arms clamp the gastric lavage tube. Pushing the push rods on both sides along the through slot causes the arc-shaped clamping arms to move, so that the slide block slides along the guide rail. The arc-shaped clamping arms clamp the gastric lavage tube and move, thereby adjusting the position of the gastric lavage tube without removing the gastric lavage tube from the housing, further improving the convenience of operation for medical staff.

[0015] Preferably, an elastic cloth is fixedly connected between the bottoms of the two arc-shaped clamping arms, and springs are fixedly connected between the two sides of the slide and the side of the adjustment cavity near the fixed base. During operation, when the arc-shaped clamping arms hold the gastric lavage tube, the elastic cloth wraps around the gastric lavage tube, reducing the probability of slippage due to the medical paraffin oil on the surface of the gastric lavage tube and improving the accuracy of moving the gastric lavage tube. At the same time, the springs allow the slide to be pushed back to its original position after the position of the gastric lavage tube is adjusted, which in turn drives the arc-shaped clamping arms and the push rod to their original positions, thus facilitating secondary operations by medical personnel.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The present invention discloses a pressure-adjustable gastric lavage device comprising a fixed base, a hanging plate, a housing, a cover plate, and a pressure plate. The hanging plate is hung on the mouth opener, the housing is installed on the fixed base, the gastric lavage tube is placed inside the slot, and then inserted into the patient's stomach through the mouth. The cover plate is installed on the top of the housing, allowing the pressure plate to slide into the slot and clamp the gastric lavage tube in conjunction with the bottom of the slot. When the patient's stomach peristalsis occurs, the patient may involuntarily swallow due to the influence of the gastric lavage tube in the mouth, causing the gastric lavage tube to move. In this case, the cover plate is loosened again, causing the pressure plate to loosen its clamping of the gastric lavage tube. Medical personnel can then adjust the position of the gastric lavage tube. Afterward, the cover plate is fixed again to lock the clamping of the gastric lavage tube. This reduces the probability of the gastric lavage tube moving due to the reduced adhesion caused by repeated use of medical tape, improves the stability of gastric lavage, and reduces the probability of needing to adjust the position of the gastric lavage tube.

[0018] 2. The pressure-adjustable gastric lavage device of the present invention comprises a square base, a silicone ring base, and medical gauze. Medical gauze soaked in medical paraffin oil is installed on the inner wall of the silicone ring base, which is then installed into the mounting hole of the square base. The square base is then installed into the oiling cavity. When medical personnel insert the tube, the gastric lavage tube passes through the silicone ring base, allowing the outer wall of the gastric lavage tube to slide against the medical gauze. This allows the medical paraffin oil on the gauze to be applied to the outer wall of the gastric lavage tube, enabling medical personnel to focus solely on inserting the tube without needing to apply the paraffin oil, thus reducing the probability of operational errors.

Detailed Implementation

[0029] 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.

[0030] Example 1

[0031] like Figure 1 As shown in the embodiment of the present invention, a pressure-adjustable gastric lavage device includes a fixed base 1, a hanging plate 2, a housing 3, a cover plate 4, and a pressure plate 5. The fixed base 1 has hanging plates 2 fixedly connected to both sides of its vertical plate. The housing 3 is installed on the inner top surface of the fixed base 1. The housing 3 has slots 6 on both sides. The cover plate 4 is fastened to the top surface of the housing 3. The pressure plate 5 is fixedly connected to both sides of the bottom surface of the cover plate 4. The side wall of the pressure plate 5 slides against the inner wall of the slot 6. A gastric lavage tube slides through the slots 6 on both sides. During operation, when the automatic gastric lavage machine performs gastric lavage on a patient, an opening device is used to open the patient's mouth and keep it open. The hanging plate 2 is hung on the opening device, so that the fixed base 1 is fixedly connected to the opening device. The housing 3 is installed on the fixed base 1. The gastric lavage tube is placed inside the slot 6. The tube is inserted into the patient's stomach through the mouth. The cover plate 4 is installed on the top of the housing 3, allowing the pressure plate 5 to slide into the groove 6. The bottom of the groove 6 clamps and fixes the gastric lavage tube. The gastric lavage tube is then connected to the inlet of the automatic gastric lavage machine. After adjusting the water pressure via the control panel, the automatic gastric lavage begins. When the patient's stomach moves, the patient may involuntarily swallow due to the influence of the gastric lavage tube in the mouth, causing the tube to move. In this case, the cover plate 4 is loosened again, causing the pressure plate 5 to loosen its clamping of the gastric lavage tube. Medical staff adjust the position of the gastric lavage tube, and then the cover plate 4 is fixed back in place to lock the clamping of the gastric lavage tube. This reduces the probability of the gastric lavage tube moving due to the reduced adhesion caused by repeated use of medical tape, improves the stability of the gastric lavage, and reduces the probability of needing to adjust the position of the gastric lavage tube.

[0032] like Figure 6As shown, the bottom surface of the fixed base 1 is provided with a sliding groove 7, and the bottom surface of the housing 3 is fixed with a slider 8. The outer wall of the slider 8 slides in cooperation with the inner wall of the sliding groove 7. The cross-section of the sliding groove 7 is convex. The slider 8 matches the sliding groove 7. The end of the slider 8 near the inside of the sliding groove 7 and the inner wall of the sliding groove 7 are both embedded with magnets 9. The magnets 9 on both sides attract each other. During operation, after the fixed base 1 is installed on the opening device, the slider 8 at the bottom of the housing 3 is slid into the inside of the sliding groove 7. The housing 3 is fixed on the fixed base 1 by the magnets 9 on both sides. The housing 3 is installed in the fixed base 1 along the axial direction of the groove 6. This makes it convenient for medical personnel to install and remove the housing 3 before removing the gastric lavage tube, reducing the probability of gastric fluid contamination inside the housing 3 when removing the gastric lavage tube.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, an oiling cavity 10 is provided inside the side of the housing 3 away from the fixed base 1. A square seat 11 is installed inside the oiling cavity 10. An installation hole 12 is provided in the middle of the square seat 11. A silicone ring seat 13 is slidably installed inside the installation hole 12. A medical gauze 14 is provided on the inner ring of the silicone ring seat 13. The medical gauze 14 is soaked in medical paraffin oil. The axis of the installation hole 12 is the same as the axis of the groove 6. When medical personnel insert the gastric lavage tube into the patient's stomach, in order to reduce the damage of the gastric lavage tube to the patient's oral cavity, trachea and gastric tube, they will apply medical paraffin oil to the outer wall of the gastric lavage tube. The existing application method requires medical personnel to... Apply medical paraffin oil to medical gauze while inserting the tube. During the procedure, install the medical gauze 14 soaked in medical paraffin oil onto the inner wall of the silicone ring seat 13, then install the silicone ring seat 13 into the mounting hole 12 of the square seat 11, and finally install the square seat 11 into the oiling cavity 10. When inserting the tube, the medical staff passes the gastric lavage tube through the silicone ring seat 13, allowing the outer wall of the gastric lavage tube to slide against the medical gauze 14, thus applying the medical paraffin oil from the medical gauze 14 to the outer wall of the gastric lavage tube. This allows the medical staff to focus solely on inserting the gastric lavage tube without needing to apply the medical paraffin oil, reducing the probability of operational errors.

[0034] like Figure 3 and Figure 4As shown, a fixing sleeve 15 is fixedly connected to both sides of the bottom surface of the oiling cavity 10. A fixing groove is formed on both sides of the inner wall of the fixing sleeve 15. A fixing post 16 is fixedly connected to both sides of the bottom surface of the square base 11. The outer wall of the fixing post 16 slides in conjunction with the inner wall of the fixing sleeve 15. Multiple rubber protrusions are fixedly connected to the outer wall of the fixing post 16, and these rubber protrusions slide in conjunction with the fixing grooves. During operation, when the square base 11 is installed inside the oiling cavity 10, the fixing post 16 is inserted into the fixing sleeve 15, causing the rubber protrusions to slide into the fixing grooves, thus fixing the fixing post 16 inside the fixing sleeve 15. Because the rubber protrusions are elastic, this facilitates installation and removal by medical personnel, and also improves the stability of the fixing sleeve 15.

[0035] like Figure 4 and Figure 7 As shown, the silicone ring seat 13 has multiple first guide strips 17 fixedly connected to its outer circumference on the side away from the fixed base 1. The mounting hole 12 has multiple first guide grooves 18 formed around its outer circumference on the side away from the fixed base 1. The outer wall of each first guide strip 17 slides against the inner wall of the first guide groove 18. The silicone ring seat 13 has multiple second guide grooves 19 formed around its outer circumference on the side near the fixed base 1. The mounting hole 12 has multiple second guide strips 20 fixedly connected to its outer circumference on the side near the fixed base 1. The outer wall of the second guide strip 20 slides into the inner wall of the second guide groove 19. During operation, when the silicone ring seat 13 is installed into the installation hole 12, the first guide strip 17 slides into the first guide groove 18, and the second guide strip 20 slides into the second guide groove 19. The slidingly installed silicone ring seat 13 is convenient for medical personnel to disassemble, clean, and disinfect. At the same time, it controls the depth of the silicone ring seat 13 installed into the installation hole 12, reducing the probability that the silicone ring seat 13 will slide out of the installation hole 12 when the gastric lavage tube is moved.

[0036] like Figure 6 and Figure 7 As shown, the inner ring of the silicone ring seat 13 has a groove 21 in the middle. A Velcro 22 is fixed inside the groove 21 and is bonded to the medical gauze 14. By fixing the Velcro 22 inside the groove 21, the medical gauze 14 is firmly bonded to the Velcro 22, thus installing the medical gauze 14 inside the groove 21. This reduces the probability that the medical gauze 14 will be pulled away from the inner ring of the silicone ring seat 13 by the gastric lavage tube. At the same time, the Velcro 22 makes it easier for medical staff to replace the medical gauze 14, improving the convenience of their work.

[0037] like Figure 6As shown, the inner ring of the silicone ring seat 13 is a conical hole. The inner ring diameter of the silicone ring seat 13 on the side closer to the fixed base 1 is smaller than the inner ring diameter on the side farther from the fixed base 1. By setting the inner ring of the silicone ring seat 13 to be conical, not only can the silicone ring seat 13 be adapted to different specifications of gastric lavage tubes, but the inner ring of the silicone ring seat 13 will also exert a certain amount of pressure on the outer wall of the gastric lavage tube, scraping off excess medical paraffin oil from the outer wall of the gastric lavage tube.

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, an adjustment cavity 23 is provided inside the housing 3 near the fixed base 1. Through slots 24 are provided on both sides of the adjustment cavity 23. A guide rail 25 is fixedly connected to the bottom surface of the adjustment cavity 23. A slide block 26 is slidably mounted on the outer side of the guide rail 25. Arc-shaped clamping arms 27 are hinged to both sides of the top of the slide block 26. A torsion spring is provided on the outer ring of the rotating shaft of the arc-shaped clamping arm 27. A push rod 28 is hinged to the side of the arc-shaped clamping arm 27 near the through slot 24. The push rod 28 passes through the through slot 24, and the outer wall of the push rod 28 is flush with the through slot 24. The inner wall of the groove 24 slides together. During operation, when the position of the gastric lavage tube needs to be adjusted, the medical staff pushes the push rods 28 on both sides into the adjustment cavity 23, so that the arc-shaped clamping arm 27 clamps the gastric lavage tube. Pushing the push rods 28 on both sides along the through groove 24 causes the arc-shaped clamping arm 27 to move, so that the slide 26 slides along the guide rail 25. The arc-shaped clamping arm 27 clamps the gastric lavage tube and moves it, thereby adjusting the position of the gastric lavage tube. It can be adjusted without removing the gastric lavage tube from the housing 3, which further improves the convenience of operation for medical staff.

[0039] like Figure 2 , Figure 3 and Figure 5 As shown, an elastic cloth 29 is fixedly connected between the bottoms of the two arc-shaped clamping arms 27, and springs 30 are fixedly connected between the two sides of the slide 26 and the side of the adjustment cavity 23 near the fixed base 1. During operation, when the arc-shaped clamping arms 27 clamp the gastric lavage tube, the elastic cloth 29 wraps the gastric lavage tube, reducing the probability of slippage due to the medical paraffin oil on the surface of the gastric lavage tube and improving the accuracy of moving the gastric lavage tube. At the same time, the springs 30 are provided so that after the position of the gastric lavage tube is adjusted, the slide 26 is pushed to reset, which drives the arc-shaped clamping arms 27 and the push rod 28 to reset, thus facilitating secondary operations by medical personnel.

[0040] Example 2

[0041] like Figure 8As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a threaded hole is provided in the middle of the pressure plate 5 on both sides, and a locking bolt 31 is installed in the internal thread of the threaded hole. The locking bolt 31 passes through the pressure plate 5. In operation, after the gastric lavage tube is inserted, the cover plate 4 is fixed to the housing 3, and the locking bolt 31 is rotated so that the locking bolt 31 moves to the bottom of the slot 6, squeezing the outer wall of the gastric lavage tube. This not only further fixes and locks the gastric lavage tube, but also makes it easier to fix gastric lavage tubes of different diameters, thus improving the applicability of the gastric lavage device.

[0042] During operation: medical gauze 14 soaked in medical paraffin oil is installed on the inner wall of silicone ring seat 13, and then silicone ring seat 13 is installed into the mounting hole 12 of square seat 11, so that guide strip 17 slides into guide groove 18 and guide strip 20 slides into guide groove 29. Fixing post 16 is inserted into fixing sleeve 15, so that rubber protrusion slides into fixing groove. Fixing post 16 is fixed inside fixing sleeve 15. Square seat 11 is installed into oiling cavity 10.

[0043] Use the mouth opener to open the patient's mouth and keep it open. Hang the hanging plate 2 on the mouth opener so that the fixed base 1 is fixed to the mouth opener. Slide the slider 8 at the bottom of the housing 3 into the inside of the groove 7. Use the magnets 9 on both sides to fix the housing 3 to the fixed base 1.

[0044] The gastric lavage tube is passed through the silicone ring seat 13 and placed inside the slot 6. It is then inserted into the patient's stomach through the mouth. The outer wall of the gastric lavage tube slides against the medical gauze 14, allowing the medical paraffin oil on the gauze 14 to be applied to the outer wall of the gastric lavage tube. This allows medical staff to focus on inserting the gastric lavage tube without having to apply the medical paraffin oil, reducing the probability of operational errors. The cover plate 4 is installed on the top of the housing 3, allowing the pressure plate 5 to slide into the slot 6. The gastric lavage tube is clamped and fixed in place by the bottom of the slot 6. The gastric lavage tube is then connected to the inlet of the automatic gastric lavage machine. After adjusting the water pressure through the control panel, the automatic gastric lavage operation begins.

[0045] When the patient's stomach moves due to peristalsis, the patient may unconsciously swallow due to the influence of the gastric lavage tube in the mouth, causing the gastric lavage tube to move. The cover plate 4 is then loosened again, and the medical staff pushes the push rods 28 on both sides into the adjustment cavity 23, so that the arc-shaped clamping arm 27 clamps the gastric lavage tube. The push rods 28 on both sides slide along the through groove 24, which drives the arc-shaped clamping arm 27 to move, so that the slide 26 slides along the guide rail 25. The arc-shaped clamping arm 27 clamps the gastric lavage tube and moves it, thereby adjusting the position of the gastric lavage tube.
