Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a vomiting prevention and anti-reverse taste device for hepatobiliary and pancreatic surgery. Background Technology

[0002] In the clinical diagnosis and treatment of hepatobiliary and pancreatic diseases, vomiting is a common symptom due to the characteristics of the disease itself, surgical trauma, anesthetic reaction and postoperative complications. Vomitus often contains corrosive components such as bile and pancreatic juice, with a stronger odor and a higher risk of bacterial growth. In current clinical practice in hepatobiliary and pancreatic surgery, open containers are often used to collect patients' vomit. Because these containers lack anti-odor structures, they cannot prevent the odor from spreading into the surrounding environment. This causes patients to inhale the odor again, leading to secondary irritation, which in turn worsens vomiting symptoms, increases the risk of respiratory infections, and negatively impacts patient recovery.

[0003] Therefore, a vomiting prevention and anti-backflow device for hepatobiliary and pancreatic surgery is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a vomiting prevention and anti-backflow device for hepatobiliary and pancreatic surgery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vomiting prevention and anti-reverse odor device for hepatobiliary and pancreatic surgery, comprising a vomit bucket, An anti-backflow unit is placed inside the vomit container and extends to the outside of the vomit container. The anti-backflow unit includes a barrier component and a filter component. The barrier component is used to prevent backflow of vomit from the external environment. The filter component is used to filter vomit gas by negative suction and reduce odor. A cleaning unit is placed above the anti-odor unit and is used to rinse and clean the vomit adhering to the anti-odor unit. The collection unit is detachably located at the bottom of the vomit container and is used to collect vomit that falls from the anti-backflow unit. Under the restriction of the anti-backflow unit, the vomit inside the vomit container can be protected from backflow to prevent the odor from escaping and causing the patient to inhale the odor again and cause secondary irritation. Under the restriction of the cleaning unit, the barrier components can be rinsed and cleaned. Under the restriction of the collection unit, vomit can be collected, and the full collection box can be quickly replaced with the vomit container.

[0006] Preferably, the barrier component includes a fixing frame connected to the inner wall of the vomit container, and a closing plate is hinged to the bottom of the fixing frame; A suction tube runs through the inside of the vomit bucket and extends to the outside of the vomit bucket. A U-shaped rod is slidably installed inside the suction tube. A first magnetic ring is connected to the inner wall of the suction tube. A second magnetic ring is connected to one end of the U-shaped rod inside the suction tube. A sealing ring is connected to the side of the second magnetic ring away from the U-shaped rod. The second magnetic ring and the first magnetic ring are magnetically repelled.

[0007] Preferably, the suction filter assembly includes a fixing ring connected to the inner wall of the straw, and a baffle is hinged to the fixing ring on the side near the first magnetic ring; The outer wall of the straw is connected to a drain pipe, and a filter plate is inserted into the end of the drain pipe; The inner wall of the pipe is connected to a platform sleeve, and a frustum is fitted inside the platform sleeve. A sliding rod is connected to the bottom of the frustum, and a spring is fitted on the outer wall of the sliding rod. A fixing plate is provided at the end of the spring away from the frustum.

[0008] Preferably, the outer wall of the second magnetic ring slides in a sealed manner with the inside of the straw, and the outer wall of the U-shaped rod slides in a sealed manner with the inside of the straw. Under the restriction of the sealed sliding, the U-shaped rod moving to the outside of the straw can draw the odor inside the vomit bucket into the straw through the straw.

[0009] Preferably, the cross-section of the platform sleeve is triangular, and the outer wall of the truncated cone is sealed to the inside of the platform sleeve. Under the converging and restraining effect inside the platform sleeve, the gas entering the drain pipe can be concentrated and pushed to push the truncated cone, causing the truncated cone to no longer be fitted with the platform sleeve, so that the drain pipe and the suction pipe are connected.

[0010] Preferably, the ends of the springs are connected to the bottom of the frustum and the top surface of the fixed plate, respectively. When the pipe no longer receives air, the frustum is not pushed by the gas. Under the elastic action of the spring, the frustum can be pushed back into the sleeve to form a sealed state.

[0011] Preferably, the cleaning unit includes a sleeve block connected to the inner wall of the vomit bucket, a sleeve rod slidably disposed inside the sleeve block, and a scraper ring connected to the end of the sleeve rod; The outer wall of the vomit bucket is connected to a liquid storage tank, the outer wall of the liquid storage tank is connected to a delivery pump, the end of the delivery pump away from the liquid storage tank is connected to a delivery ring, and the inner wall of the delivery ring is connected to a nozzle.

[0012] Preferably, the outer wall of the nozzle penetrates through the vomit container and extends into the interior of the vomit container, and the delivery ring is fitted around the outside of the vomit container. Under the constraint of the delivery ring, the delivery pump can deliver cleaning fluid to each nozzle through the delivery ring.

[0013] Preferably, the collection unit includes a collection box, which is connected to a vomit bucket via a connecting component; The connecting assembly includes a frame connected to the outer wall of the bottom of the vomit container. A hook is hinged to the inner side of the frame, and a positioning post is provided at the end of the hook. A retaining ring is fitted on the outer wall of the collection box, and a positioning groove is provided at the bottom of the retaining ring.

[0014] Preferably, the inner wall of the collection box is sloped, and the outer wall of the collection box is fitted inside the bottom of the vomit bucket. Under the constraint of the collection box, vomit can be collected in a concentrated manner.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention is applicable to clinical diagnosis and treatment in hepatobiliary and pancreatic surgery, and can solve the problems of patient vomit collection and odor diffusion. The vomit container is equipped with a movable base for easy and flexible use by patients; In the anti-odor unit, the first and second magnetic rings repel each other, driving the second magnetic ring to move the sealing ring and U-shaped rod towards the fixed ring, squeezing multiple closing plates to close them, thus isolating the inside of the vomit container. When vomit falls into the closing plate, its gravity compresses the closing plate to rotate around the hinge of the fixed frame, pushing the U-shaped rod and the second magnetic ring towards the first magnetic ring. The closing plate opens and guides the vomit into the container. After the vomit has slid out, the magnetic repulsion drives the U-shaped rod to reset, squeezing the closing plate to close again, isolating the odor inside the container and preventing the patient from inhaling the odor, which could cause secondary vomiting, worsen symptoms, or increase the risk of respiratory infection. When the cleaning unit is working, pressing the sleeve rod causes the scraper ring to slide and scrape along the outer wall of the closing plate, simultaneously triggering the closing plate to open. This pushes the U-shaped rod to slide outwards towards the suction tube. The sealing ring and the inner wall of the suction tube are sealed together, drawing in gas from the bucket during the sliding motion. The gas enters the suction tube through the fixing ring, pushing the baffle to rotate around the hinge, thus drawing in gas from the bucket. During this process, the discharge tube remains sealed due to the tight fit between the frustum and the sleeve. After the scraper ring stops pressing, the magnetic repulsion drives the U-shaped rod to reset, the closing plate closes, the suction tube stops drawing in air, and the baffle returns to its original position by gravity, sealing the fixing ring. The sealing ring pushes the gas in the suction tube into the discharge tube, and the gas pushes up the frustum to compress the spring. Odorous gas is filtered through the suction filter plate and then discharged. This reciprocating operation reduces odors in the bucket and prevents odors from reaching the patient. During cleaning, the delivery pump is activated to deliver the cleaning solution containing bactericidal and deodorizing ingredients from the storage tank to the delivery ring, which is then sprayed onto the surface of the closing plate through the nozzle. The sliding scraper ring, combined with the liquid rinsing, cleans the closing plate and the inner wall of the vomit container. The vomit container is made of smooth stainless steel, which makes it difficult for dirt to adhere, greatly improving the convenience and thoroughness of cleaning. The bottom of the vomit container is equipped with a disposable collection box with a sloping inner wall design, which can efficiently guide and collect vomit and avoid cross-infection. Push the collection box upward to disengage the retaining ring positioning groove from the positioning post of the hook, and rotate the hook to remove the collection box. When replacing the collection box, the sloping surface of the retaining ring squeezes the hook to rotate around the hinge of the connecting frame. After the positioning post is aligned with the positioning groove, pull down the collection box to complete the snap-fit ​​fixation. Attached Figure Description

[0027] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings. Example 1

[0028] Reference Figure 1 and Figure 2This is the first embodiment of the present invention, which provides a vomiting prevention and anti-backflow device for hepatobiliary and pancreatic surgery, including a vomiting bucket 1. The anti-odor unit 3 is placed inside the vomit container 1 and extends to the outside of the vomit container 1. The anti-odor unit 3 includes a barrier component and a filter component. The barrier component is used to block the vomit from the external environment and prevent odor from backflow. The filter component is used to filter the vomit gas by negative suction and reduce the odor. Cleaning unit 4 is placed above anti-odor unit 3 and is used to rinse and clean the vomit adhering to anti-odor unit 3. Collection unit 5 is detachably located at the bottom of vomit container 1 and is used to collect vomit that falls from anti-odor unit 3.

[0029] Under the restriction of the anti-odor unit 3, the vomit inside the vomit bucket 1 can be treated to prevent the odor from escaping and causing the patient to inhale the odor again, which would cause secondary irritation. Under the restriction of the cleaning unit 4, the barrier components can be rinsed and cleaned. Under the restriction of the collection unit 5, the vomit can be collected, and the full collection box 54 can be quickly replaced with the vomit bucket 1. Example 2

[0030] Reference Figures 3-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The barrier assembly includes a fixed frame 31, which is connected to the inner wall of the vomit container 1, and a closing plate 32 is hinged to the bottom of the fixed frame 31. A straw 33 runs through the inside of the vomit container 1 and extends to the outside of the vomit container 1. A U-shaped rod 35 is slidably arranged inside the straw 33. A first magnetic ring 34 is connected to the inner wall of the straw 33. A second magnetic ring 37 is connected to one end of the U-shaped rod 35 inside the straw 33. A sealing ring 36 is connected to the side of the second magnetic ring 37 away from the U-shaped rod 35. The second magnetic ring 37 and the first magnetic ring 34 are magnetically repelled. The suction filter assembly includes a fixing ring 38 connected to the inner wall of the straw 33, and a baffle 39 is hinged to the side of the fixing ring 38 near the first magnetic ring 34; The outer wall of the straw 33 is connected to the drain pipe 310, and the end of the drain pipe 310 is inserted into the filter plate 316. The inner wall of the pipe 310 is connected to a platform sleeve 311, and a frustum 312 is fitted inside the platform sleeve 311. A sliding rod 313 is connected to the bottom of the frustum 312, and a spring 314 is fitted on the outer wall of the sliding rod 313. A fixing plate 315 is provided at the end of the spring 314 away from the frustum 312.

[0031] The outer wall of the second magnetic ring 37 is sealed and slides inside the straw 33, and the outer wall of the U-shaped rod 35 is sealed and slides inside the straw 33. Under the restriction of the sealed sliding, the U-shaped rod 35 moving to the outside of the straw 33 can draw the odor inside the vomit bucket 1 into the straw 33 through the straw 33.

[0032] The platform sleeve 311 has a triangular cross-section, and the outer wall of the truncated cone 312 is sealed to the inside of the platform sleeve 311. Under the converging and restricting effect inside the platform sleeve 311, the gas entering the drain pipe 310 can be concentrated and pushed to the truncated cone 312, causing the truncated cone 312 to no longer be fitted with the platform sleeve 311, so that the drain pipe 310 and the suction pipe 33 are connected.

[0033] The ends of the spring 314 are connected to the bottom of the frustum 312 and the top surface of the fixed plate 315 respectively. When the pipe 310 no longer receives air, the frustum 312 is not pushed by the gas. Under the elastic action of the spring 314, the frustum 312 can be pushed back into the sleeve tube 311 to form a sealed state.

[0034] In the clinical diagnosis and treatment of hepatobiliary and pancreatic diseases, patients often experience vomiting, requiring the collection and treatment of vomit. A vomit bucket 1 is pulled to collect the vomit, and the movable seat 2 located below the vomit bucket 1 allows for easy access by the patient. Due to the magnetic repulsion between the second magnetic ring 37 and the first magnetic ring 34, the second magnetic ring 37 can drive the sealing ring 36 and the U-shaped rod 35 towards the fixed ring 38. The end of the U-shaped rod 35 away from the second magnetic ring 37 presses against the outer wall of the closing plate 32, causing the multiple closing plates 32 to be in a closed initial state inside the vomit bucket 1. When vomit falls onto the closing plate 32, its weight compresses the plate, causing it to rotate around its hinge point with the bottom of the fixed frame 31. This causes the outer wall of the closing plate 32 to press against the U-shaped rod 35, which in turn moves the second magnetic ring 37 and the sealing ring 36 towards the first magnetic ring 34. The rotating and opening closing plate 32 then conveys the vomit into the vomit container 1, completing the vomit collection process. After the vomit has slid off the closing plate 32, the magnetic repulsion between the second magnetic ring 37 and the first magnetic ring 34 pushes the U-shaped rod 35 back to its original position, causing it to press against the closing plate 32. This closes the multiple closing plates 32, isolating the vomit container 1 and preventing backflow of odors. This operation isolates the vomit from the patient's vomiting environment, preventing the patient from inhaling odors that could trigger secondary vomiting, worsen vomiting symptoms, and increase the risk of respiratory infection.

[0035] When cleaning the vomit residue on the closing plate 32, cleaning can be performed using the cleaning unit 4. The scraper ring 43 in the cleaning unit 4 can scrape and clean the closing plate 32. At the same time, the closing plate 32 is squeezed and opened. At this time, the U-shaped rod 35 is squeezed and slides outward from the straw 33. Due to the sealing of the outer wall of the sealing ring 36 and the inside of the straw 33, the odor inside the vomit container 1 can be sucked into the straw 33 under its restriction. Since the gas enters the straw 33 from the direction of the fixing ring 38, the baffle 39 is pushed by the gas and rotates around the hinge point with the fixing ring 38 as the rotation center, sucking the gas into the straw 33. When the sealing ring 36 draws air from the suction tube 33, the exhaust pipe 310 is restricted by the air drawing, which draws the frustum 312 inside the platform sleeve 311 toward the platform sleeve 311. Since the frustum 312 and the platform sleeve 311 are sealed together, the sealing ring 36 can only draw gas from the inside of the vomit bucket 1 through the suction tube 33, and the exhaust pipe 310 is in a closed state. When the scraper ring 43 stops pressing on the closing plate 32, the U-shaped rod 35 is pushed back to its original position by the magnetic repulsion between the second magnetic ring 37 and the first magnetic ring 34, causing the U-shaped rod 35 to press and close the closing plate 32. At this time, the straw 33 stops sucking air, and the baffle 39 returns to its original position under the action of gravity and closes the fixing ring 38. The sealing ring 36 pushes the gas inside the straw 33 into the drain pipe 310 connected to the outer wall of the straw 33. When the truncated cone 312 is pushed by the gas, it drives the slide rod 313 to slide inside the fixing plate 315 and compresses the spring 314 sleeved on the outer wall of the slide rod 313. At this time, the truncated cone 312 is no longer sealed with the sleeve tube 311, and the odor gas inside the straw 33 can be transported into the drain pipe 310, filtered and adsorbed by the suction plate 316, and then discharged to the outside through the drain pipe 310. The reciprocating operation can reduce the odor inside the vomit bucket 1 and reduce the unpleasant smell. This operation can filter and reduce odors inside the vomit container 1, improve the air quality around the patient, and negatively absorb the backflow gas generated when the closing plate 32 is opened, preventing odors inside the vomit container 1 from hitting the patient. Example 3

[0036] Reference Figure 7 and Figure 8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as follows: The cleaning unit 4 includes a sleeve block 41 connected to the inner wall of the vomit bucket 1, a sleeve rod 42 slidably disposed inside the sleeve block 41, and a scraper ring 43 connected to the end of the sleeve rod 42; The outer wall of the vomit bucket 1 is connected to a liquid storage tank 44, the outer wall of the liquid storage tank 44 is connected to a delivery pump 45, the end of the delivery pump 45 away from the liquid storage tank 44 is connected to a delivery ring 46, and the inner wall of the delivery ring 46 is connected to a nozzle 47.

[0037] The outer wall of the nozzle 47 penetrates the vomit container 1 and extends into the interior of the vomit container 1. The delivery ring 46 is fitted around the outside of the vomit container 1. Under the restriction of the delivery ring 46, the delivery pump 45 can deliver cleaning fluid to each nozzle 47 through the delivery ring 46.

[0038] After the anti-odor unit 3 collects the patient's vomit, vomit mucus easily adheres to the closing plate 32, requiring cleaning to avoid odor irritating the patient. At this time, the delivery pump 45 is activated, which delivers the cleaning solution inside the storage tank 44 into the delivery ring 46, and sprays it out through the nozzle 47. The nozzle 47 rinses the closing plate 32. At this time, the sleeve rod 42 is pressed, causing it to slide inside the sleeve block 41. The sleeve rod 42 drives the scraper ring 43 fixedly installed at its end to slide against the outer wall of the closing plate 32, scraping and cleaning the closing plate 32. At the same time, it works in conjunction with the rinsing of the cleaning solution sprayed by the nozzle 47. The storage tank 44 contains bactericidal and deodorizing substances, which can assist in cleaning the closing plate 32 and the inner wall of the vomit bucket 1. Since the main body of the vomit bucket 1 is made of stainless steel, its surface has smooth characteristics, which can effectively reduce the probability of dirt adhesion, making it easy to clean quickly and achieve a clean state. This structure can scrape and clean the closing plate 32 and rinse it, and the cleaning unit 4 can rinse from top to bottom of the vomit bucket 1 so that the vomit bucket 1 is clean when it is used again. Example 4

[0039] Reference Figure 9 and Figure 10 This is the fourth embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as follows: Collection unit 5 includes collection box 54, which is connected to vomit container 1 via a connecting component; The connecting assembly includes a frame 51 connected to the outer wall of the bottom end of the vomit container 1. A hook 52 is hinged to the inner side of the frame 51. A positioning post 53 is provided at the end of the hook 52. A retaining ring 55 is sleeved on the outer wall of the collection box 54. A positioning groove 56 is provided at the bottom of the retaining ring 55.

[0040] The inner wall of the collection box 54 is sloped, and the outer wall of the collection box 54 is fitted inside the bottom of the vomit bucket 1. Under the restriction of the collection box 54, vomit can be collected in a concentrated manner.

[0041] When a patient vomits into the vomit container 1, the vomit is collected in the collection box 54. Since the collection box 54 is a disposable product, it avoids cross-infection to other patients caused by the use of the vomit container by patients with infectious diseases. When the collection box 54 has collected a large amount of vomit, push the collection box 54 upwards to cause the positioning groove 56 at the bottom of the retaining ring 55 to no longer engage with the positioning post 53 connected to the hook 52. Rotate the hook 52 so that it is no longer engaged with the outer wall of the retaining ring 55, and the collection box 54 can be quickly removed from the bottom of the vomit container 1. Insert the new collection box 54 into the bottom of the vomit container 1. The retaining ring 55 slides and presses against the inclined surface of the hook 52, causing the hook 52 to rotate around the hinge point with the connecting frame 51 as the center of rotation. When the retaining ring 55 no longer presses against the hook 52, the hook 52 returns to its original position under the action of gravity, causing the positioning post 53 to align with the positioning groove 56. Pull the collection box 54 down to make the positioning groove 56 engage with the positioning post 53, thus completing the quick installation of the collection box 54 and the vomit container 1. Because the inner wall of the collection box 54 is inclined, it can better guide and collect vomit into the collection box 54. This structure can collect vomit through the collection box 54, and the collection box 54 and the vomit container 1 can be quickly disassembled and assembled for quick replacement of the full collection box 54.

[0042] It is worth noting that the delivery pump 45 is controlled by a controller. Since the controller is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0043] The above are merely illustrative embodiments of the present invention and are not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention. Furthermore, it should be noted that the components of the present invention are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, the present invention naturally covers other combinations and specific applications related to the inventive points of this case.
