Description

Technical Field

[0001] This invention relates to the field of saliva treatment technology, and more specifically, to a saliva treatment device and method for tuberculosis wards. Background Technology

[0002] Tuberculosis wards are isolation and treatment areas specifically used to treat tuberculosis patients. As a respiratory infectious disease, tuberculosis can cause patients to expel droplets containing Mycobacterium tuberculosis into the air through coughing, sputum production, and sneezing. If the saliva droplets expelled by patients are not properly collected and disinfected, cross-infection can easily occur in the ward, threatening the health of medical staff and other caregivers. Currently, most tuberculosis wards are only equipped with ordinary trash cans or open containers to collect patients' saliva secretions. These containers lack effective sealing and anti-spreading structures as well as corresponding disinfection and sterilization functions. Saliva containing pathogens is prone to leakage and evaporation, increasing the risk of pathogen transmission. Therefore, it is necessary to propose a safer and more standardized saliva treatment device and method for tuberculosis wards to address the shortcomings of existing technologies.

[0003] According to patent document CN113842327A, a saliva processing device for tuberculosis wards is disclosed, belonging to the field of medical equipment technology. This device includes a shell, a sealing cap, and a foot pedal. A saliva dish is provided on the upper surface of the shell, and a ring-shaped disinfectant pipe is fixedly installed on the upper surface of the saliva dish. A disinfectant nozzle is fixedly installed on the inner side of the ring-shaped disinfectant pipe. A support plate is fixedly installed inside the shell, and a saliva processing box is fixedly installed on the upper surface of the support plate. A first connecting pipe is fixedly installed at the bottom of the saliva dish, and the bottom of the first connecting pipe is fixedly connected to the upper surface of the saliva processing box. A first disinfection lamp is fixedly installed on the top wall inside the saliva processing box. A saliva collection box is placed inside the saliva processing box. The sealing cap effectively prevents saliva droplets from flying into the air, the foot pedal prevents direct contact with saliva, and the combination of a handle and wheels facilitates movement. Triple disinfection improves disinfection efficiency and quality.

[0004] In tuberculosis wards, trash cans are typically used to store saliva-containing contaminants generated by patients. These collection methods mostly lack enclosed protective structures, and when patients spit or discard contaminants, it is easy to cause the spread of germ-laden droplets, increasing the risk of cross-infection in the ward. At the same time, during the daily cleaning and removal of collected materials, medical staff also need to directly contact the trash cans, posing a high risk of occupational exposure. Existing covered collection devices mostly lack targeted disinfection procedures, which may result in the inability to promptly inactivate the collected saliva and the bacteria it carries. After use, manual opening and cleaning are also required, making the process cumbersome and lacking in protection, which is difficult to meet the epidemic prevention needs of tuberculosis wards. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a saliva treatment device and method for tuberculosis wards. The technical problem this invention aims to solve is that using trash cans to store saliva-containing contaminants generated by patients often lacks a closed protective structure. When patients spit or discard contaminants, it can easily cause the spread of germ-laden droplets, increasing the risk of cross-infection in the ward. At the same time, during the daily cleaning and collection process, medical staff also need to directly contact the trash cans, posing a high risk of occupational exposure. Existing covered collection devices mostly lack targeted disinfection procedures, which may result in the inability to promptly inactivate the collected saliva and the bacteria it carries. After use, manual opening and cleaning are also required, making the process cumbersome and lacking in protection, which is difficult to meet the epidemic prevention needs of tuberculosis wards.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A saliva processing device for a tuberculosis ward includes a storage box, a saliva delivery mechanism fixedly connected to the top of the inner wall of the storage box, U-shaped guide rods fixedly connected to the four sides of the top of the inner wall of the storage box, and a closed opening provided at the top of the saliva delivery mechanism.

[0013] As a further aspect of the present invention: the funnel component includes a funnel, with C-shaped connecting side plates fixedly connected to the left and right sides of the top of the funnel, and columnar rods fixedly connected to the inner walls of the two C-shaped connecting side plates. Vertical pipes are fixedly connected to the four sides of the bottom of the funnel, and liquid inlet heads are fixedly connected to the bottom of the two sets of vertical pipes. The bottom ends of the two sets of liquid inlet heads are fixedly connected to the top of the two sets of vertical pipes. Gas pipes are fixedly connected to the outer walls of the two sets of liquid inlet heads, and the ends of the two sets of gas pipes away from the liquid inlet heads are fixedly connected to the outside of the two sets of suction cylinders.

[0014] As a further embodiment of the present invention: an inverted L-shaped connecting rod is fixedly connected to the outer side of each of the two sets of liquid inlet heads, a middle block is fixedly connected to the inner side of each of the two sets of liquid inlet heads, and the bottom of each of the two sets of inverted L-shaped connecting rods is fixedly connected to the four sides of the inner wall of the storage tank on the outer side of each of the two sets.

[0015] As a further embodiment of the present invention: the closure includes two rotating side plates, and plastic cloth is fixedly connected to the front and rear sides of the inner sides of the two rotating side plates. The bottom inner walls of the two rotating side plates are rotatably connected to the outer walls of the two columnar rods, and an inverted L-shaped rotating plate is fixedly connected to the bottom of the outer sides of the two rotating side plates.

[0016] As a further embodiment of the present invention: rotating short rods are rotatably connected to the front and rear sides of the inner bottom of the two inverted L-shaped rotating plates, and bottom lifting plates are rotatably connected to the bottom of the outer sides of the two sets of rotating short rods. Push-pull rods are fixedly connected to the front and rear sides of the bottom of the two bottom lifting plates, and horizontal L-shaped push-pull rods are fixedly connected to the bottom of the two sets of push-pull rods.

[0017] As a further embodiment of the present invention: a columnar short block is fixedly connected to the inner side of the bottom of the left and right sets of horizontal L-shaped push-pull rods, and the bottom of the columnar short blocks of the left and right sets is fixedly connected to the top of the two sets of lifting blocks.

[0018] In addition, the present invention also relates to a saliva treatment device and method for a tuberculosis ward, comprising the following steps:

[0019] Step 1: Fix the saliva processing device in the designated area of ​​the tuberculosis ward. The storage box is pre-filled with disinfectant. Adjust the funnel to a height that is convenient for patients to spit out their saliva.

[0020] Step 2: The patient spits saliva toward the funnel, and leaves the device area after completing the procedure;

[0021] Step 3: The electric push rod is activated to push the lifting base plate downward. The lifting base plate drives the push and pull uprights on all four sides to move downward simultaneously, thereby pulling the two sets of lifting blocks to slide downward along the inner wall of the side guide block.

[0022] Step 4: During the downward movement of the lifting block, the V-shaped rotating block rotates along the V-shaped rotating block support. The bottom end of the V-shaped rotating block pulls the piston down along the inner wall of the suction cylinder, creating a negative pressure inside the suction cylinder and drawing air from the inside of the liquid inlet through the gas pipe.

[0023] Step 5: The short column at the top of the lifting block moves the horizontal L-shaped push-pull rod down synchronously with the push-pull rod. The push-pull rod pulls the bottom lifting plate down, and then the short rod is rotated to pull the inverted L-shaped rotating plate to rotate, causing the two rotating side plates to rotate in opposite directions along the column rod. Finally, the top opening of the funnel is completely sealed by the plastic sheet.

[0024] Step Six: The saliva collected by the funnel flows through the funnel into the vertical tube under negative pressure, and then enters the bottom tube through the inlet head and the vertical tube, and is finally transported to the storage tank. After entering the storage tank, the saliva is mixed with the preset disinfectant inside, and after disinfection, it is stored in a centralized manner.

[0025] Step 7: Keep the funnel closed to prevent residual tuberculosis bacteria from spreading into the ward environment through the air. The negative pressure accelerates saliva delivery while reducing saliva residue adhering to the inner wall of the funnel, further reducing the risk of bacterial spread.

[0026] Step 8: When the amount of saliva waste liquid inside the storage box reaches the removal threshold, medical staff, after taking protective measures, open the pre-set drain valve of the storage box to discharge the disinfected waste liquid and complete the removal operation.

[0027] Step 9: After cleaning, close the drain valve, replenish the storage tank with disinfectant, start the electric push rod in reverse to reset all components, open the funnel opening with the plastic sheet, and wait for the next patient to use it.

[0028] The beneficial effects of this invention are as follows:

[0029] This invention, by incorporating a storage box, a saliva delivery mechanism, and a sealing opening, achieves the technical effects of automatically sealing the operating opening after spitting out saliva, accelerating saliva delivery, and preventing residue. It effectively solves the problem of traditional trash cans lacking sealing protection, leading to the spread of bacteria-laden droplets and increased risk of cross-infection when discarding pollutants. Through automatic sealing combined with negative pressure delivery, the airborne transmission path of tuberculosis bacteria is cut off from the pollutant generation stage, significantly reducing the possibility of cross-infection in wards.

[0030] This device eliminates the need for medical staff to manually operate it for cleaning and disposal. Simply opening the pre-set drain valve allows for the unified discharge of disinfectant waste, preventing medical staff from directly contacting contaminants during the disposal process and significantly reducing their occupational exposure risk.

[0031] Meanwhile, this device can centrally disinfect and store collected saliva contaminants, and can inactivate tuberculosis bacteria carried in saliva immediately after collection. This makes up for the shortcomings of existing covered storage devices that lack targeted disinfection and cannot inactivate bacteria in time. The entire collection, sealing, transportation and disinfection process does not require manual opening of the lid. The process is simple and highly protective, and can fully meet the epidemic prevention needs of tuberculosis wards. Attached Figure Description

The bottoms of both sets of columnar short blocks 328 are fixedly connected to the tops of the two sets of lifting blocks 210.

[0046] When saliva needs to be processed, the patient spits saliva toward the funnel 311. After the patient leaves after completing the spitting operation, the electric push rod 215 is activated to push the lifting base plate 216 downward. The lifting base plate 216 drives the four push-pull uprights 217 to move downward simultaneously, thereby pulling the two sets of lifting blocks 210 to slide downward along the inner wall of the side guide block 27. During the downward movement of the lifting blocks 210, the V-shaped rotating block 29 is driven to rotate along the V-shaped rotating block support block 28. The bottom end of the V-shaped rotating block 29 pulls the piston 212 to move downward along the inner wall of the air extraction cylinder 211, so that a negative pressure is formed inside the air extraction cylinder 211, and the air inside the liquid inlet head 315 is extracted through the gas pipe 316.

[0047] At the same time, the columnar short block 328 at the top of the lifting block 210 drives the horizontal L-shaped push-pull rod 327 and the push-pull rod 326 to move down synchronously. The push-pull rod 326 pulls the bottom lifting plate 325 down, and then pulls the inverted L-shaped rotating plate 323 to rotate by rotating the short rod 324, which drives the two rotating side plates 321 to rotate in opposite directions along the columnar rod 313. Finally, the top opening of the funnel 311 is completely sealed by the plastic sheet 322 to prevent tuberculosis bacteria from spreading into the ward environment through the air.

[0048] Saliva flows through funnel 311 into vertical pipe 314, and finally through inlet head 315 and vertical pipe 23 into bottom pipe 214, and is transported to storage tank 1 for centralized disinfection and storage. The negative pressure formed by suction can also accelerate the saliva transport process, avoid saliva residue sticking to the inner wall of the funnel, and further reduce the risk of bacterial spread. When it is necessary to centrally clean and dispose of the saliva waste liquid inside storage tank 1, simply open the preset drain valve of storage tank 1 to discharge the disinfected waste liquid in a unified manner and complete the cleaning operation.

[0049] In addition, the present invention also relates to a saliva treatment device and method for a tuberculosis ward, comprising the following steps:

[0050] Step 1: Fix the saliva processing device in the designated area of ​​the tuberculosis ward. Pre-fill the storage box 1 with disinfectant. Adjust the funnel 311 to a height that is convenient for the patient to spit out saliva.

[0051] Step 2: The patient spits saliva toward funnel 311, and leaves the device area after completing the operation;

[0052] Step 3: The electric push rod 215 is activated to push the lifting base plate 216 downward. The lifting base plate 216 drives the push-pull uprights 217 on all four sides to move downward simultaneously, thereby pulling the two sets of lifting blocks 210 to slide downward along the inner wall of the side guide block 27.

[0053] Step 4: During the downward movement of the lifting block 210, the V-shaped rotating block 29 is driven to rotate along the V-shaped rotating block support block 28. The bottom end of the V-shaped rotating block 29 pulls the piston 212 downward along the inner wall of the suction cylinder 211, so that a negative pressure is formed inside the suction cylinder 211, and the air inside the liquid inlet head 315 is extracted through the gas pipe 316.

[0054] Step 5: The columnar short block 328 at the top of the lifting block 210 drives the horizontal L-shaped push-pull rod 327 and push-pull rod 326 to move down synchronously. The push-pull rod 326 pulls the bottom lifting plate 325 down, and then pulls the inverted L-shaped rotating plate 323 to rotate by rotating the short rod 324, which drives the two rotating side plates 321 to rotate in opposite directions along the columnar rod 313. Finally, the top opening of the funnel 311 is completely sealed by the plastic sheet 322.

[0055] Step 6: The saliva collected by the funnel 311 flows into the vertical tube 314 under negative pressure, and then enters the bottom tube 214 through the inlet head 315 and the vertical tube 23, and is finally transported to the storage box 1. After entering the storage box 1, the saliva is mixed with the preset disinfectant inside, and after disinfection, it is stored in a centralized manner.

[0056] Step 7: Keep the funnel 311 closed to prevent residual tuberculosis bacteria from spreading into the ward environment through the air. The negative pressure accelerates saliva delivery while reducing saliva residue adhering to the inner wall of the funnel, further reducing the risk of bacterial spread.

[0057] Step 8: When the amount of saliva waste liquid inside storage box 1 reaches the removal threshold, medical staff, after taking protective measures, open the pre-set drain valve of storage box 1 to discharge the disinfected waste liquid and complete the removal operation.

[0058] Step 9: After cleaning, close the drain valve, replenish the disinfectant to storage tank 1, start the electric push rod 215 in reverse to reset all components, and open the funnel 311 with plastic sheet 322, ready for the next patient to use.

[0059] Working principle of the invention: When saliva needs to be processed, the patient spits saliva towards the funnel 311. After the patient leaves, the electric push rod 215 is activated to push the lifting base plate 216 downward. The lifting base plate 216 drives the four push-pull uprights 217 to move downward simultaneously, thereby pulling the two sets of lifting blocks 210 to slide downward along the inner wall of the side guide block 27. During the downward movement of the lifting blocks 210, the V-shaped rotating block 29 is driven to rotate along the V-shaped rotating block support block 28. The bottom end of the V-shaped rotating block 29 pulls the piston 212 downward along the inner wall of the suction cylinder 211, creating a negative pressure inside the suction cylinder 211. The liquid is then drawn from the inside of the inlet head 315 through the gas pipe 316. Meanwhile, the columnar short block 328 at the top of the lifting block 210 drives the horizontal L-shaped push-pull rod 327 and push-pull rod 326 to move down synchronously. The push-pull rod 326 pulls the bottom lifting plate 325 down, and then pulls the inverted L-shaped rotating plate 323 to rotate by rotating the short rod 324, which drives the two rotating side plates 321 to rotate in opposite directions along the columnar rod 313. Finally, the top opening of the funnel 311 is completely sealed by the plastic sheet 322 to prevent tuberculosis bacteria from spreading into the ward environment through the air. Saliva flows through the funnel 311 into the vertical pipe 314, and finally enters the bottom pipe 214 through the liquid inlet head 315 and the vertical pipe 23, and is transported to the storage box 1 for centralized disinfection and storage.

10. A saliva processing device for a tuberculosis ward, as described in any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Fix the saliva processing device in the designated area of ​​the tuberculosis ward, pre-fill the storage box (1) with disinfectant, and adjust the funnel (311) to a height that is convenient for the patient to spit out saliva; Step 2: The patient spits out saliva toward the funnel (311), and leaves the device area after completing the operation; Step 3: The electric push rod (215) is activated to push the lifting base plate (216) downward. The lifting base plate (216) drives the push-pull uprights (217) on all four sides to move downward in sync, thereby pulling the two sets of lifting blocks (210) to slide downward along the inner wall of the side guide block (27). Step 4: During the downward movement of the lifting block (210), the V-shaped rotating block (29) is driven to rotate along the V-shaped rotating block support block (28). The bottom end of the V-shaped rotating block (29) pulls the piston (212) downward along the inner wall of the suction cylinder (211), so that a negative pressure is formed inside the suction cylinder (211), and the air inside the liquid inlet head (315) is drawn out through the gas pipe (316). Step 5: The columnar short block (328) at the top of the lifting block (210) drives the horizontal L-shaped push-pull rod (327) and the push-pull rod (326) to move down synchronously. The push-pull rod (326) pulls the bottom lifting plate (325) down, and then pulls the inverted L-shaped rotating plate (323) to rotate by rotating the short rod (324), which drives the two rotating side plates (321) to rotate in opposite directions along the columnar rod (313). Finally, the top opening of the funnel (311) is completely sealed by the plastic sheet (322). Step 6: The saliva collected by the funnel (311) flows into the vertical tube (314) under negative pressure, and then enters the bottom tube (214) through the inlet head (315) and the vertical tube (23), and is finally transported to the storage box (1). After entering the storage box (1), the saliva is mixed with the preset disinfectant inside, and after disinfection, it is stored in a centralized manner. Step 7: Keep the funnel (311) closed to prevent residual tuberculosis bacteria from spreading into the ward environment through the air. The negative pressure accelerates saliva delivery while reducing saliva residue adhering to the inner wall of the funnel, further reducing the risk of bacterial spread. Step 8: When the amount of saliva waste liquid inside the storage box (1) reaches the removal threshold, the medical staff will open the pre-set drain valve of the storage box (1) after taking protective measures, and discharge the disinfected waste liquid in a unified manner to complete the removal operation. Step 9: After cleaning, close the drain valve, add disinfectant to the storage box (1), start the electric push rod (215) in reverse to reset all parts, and open the funnel (311) with the plastic sheet (322) to wait for the next patient to use.
