Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and in particular to a multifunctional sputum suction device. Background Art

[0002] In the early days of medicine, a variety of primitive methods were tried to address the problem of blocked airway secretions. Before the 19th century, doctors primarily used physical methods such as back tapping and postural drainage to help patients expel sputum. However, these methods had limited effectiveness for patients with deep airway obstruction or those unable to cough up sputum. It wasn't until the mid-19th century, with the development of anesthesiology and surgery, that doctors began to realize the importance of airway patency to surgical safety. Initial attempts at manual suctioning with metal catheters began. By the 21st century, suctioning had become a fundamental procedure in departments like critical care and respiratory medicine, and the devices were becoming increasingly intelligent and multifunctional.

[0003] In current clinical applications, the ultraviolet disinfection components of most suction devices are fixedly installed, resulting in poor disinfection effects in the remote corners and areas where bacteria are prone to accumulate inside the equipment. In addition, some sputum processing boxes directly discharge the sputum after using the diluent to dilute the sputum. Because the residual liquid stains and sputum deposits at the bottom of the box are difficult to completely remove, it is easy to form a disinfection blind spot, posing an infection risk to medical staff. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art and to propose a multifunctional sputum suction device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A multifunctional sputum suction device comprises a sputum suction processing box, the side of the sputum suction processing box is fixedly connected to a negative pressure pump body, the negative pressure pump body passes through the sputum suction processing box and is connected to the negative pressure connecting block pipe, the interior of the sputum suction processing box is fixedly connected to a connecting frame, the inner wall of the connecting frame is fixedly connected to an inner rack of the frame, the inner rack of the frame is meshed with an inner gear of the frame, one end of the inner gear of the frame away from the connecting frame is fixedly connected to a threaded rod, the threaded rod is threadedly connected to an ultraviolet disinfection lamp cover plate, one end of the threaded rod away from the inner gear of the frame is fixedly connected to a first bevel gear, the first bevel gear is meshed with a second bevel gear, the second bevel gear is transmission-connected with a through rod, the through rod passes through the support frame and is fixedly connected to a half-side gear, the bottom of the support frame is fixedly connected to a sliding groove plate, the sliding groove plate is slidably connected to an elliptical ring, the inside of the elliptical ring is fixedly connected to the first inner wall rack, the inside of the elliptical ring is fixedly connected to the second inner wall rack, the side of the elliptical ring is fixedly connected to the second disinfection strip, and the side of the elliptical ring away from the second disinfection strip is fixedly connected to the first cleaning strip.

[0007] The above technical solution further includes:

[0008] The connecting frame is slidably connected to the cross support frame, and an auxiliary block for supporting the rotation of the first bevel gear is provided inside the cross support frame. The second bevel gear is connected to a belt, and the end of the belt away from the second bevel gear is connected to a through rod. The supporting frame is fixed below the cross support frame.

[0009] A handle is provided on the top of the sputum suction processing box, and an opening for inserting a sputum suction tube is opened on the top of the sputum suction processing box.

[0010] A diluent box for conveying dilution liquid into the interior is provided on the side of the sputum suction processing box. A control panel is provided on the side of the sputum suction processing box. Buttons are also provided on the surface of the control panel.

[0011] A liquid outlet valve for discharging the diluent is provided on one side of the sputum suction treatment box.

[0012] A dryer for drying the interior of the sputum suction processing box is hung inside the box.

[0013] The ultraviolet disinfection lamp cover is slidably connected to the cross support frame. The sliding connection design enables the ultraviolet disinfection lamp cover to perform linear reciprocating motion along the track of the cross support frame, and cooperates with the transmission structure of the gear and threaded rod inside the frame to form a three-dimensional disinfection path. When the gear inside the frame rotates, the threaded rod drives the cross support frame to slide on the side of the connecting frame, and simultaneously drives the ultraviolet disinfection lamp cover to move up and down the inner wall of the sputum suction treatment box, which can cover dead corners such as the top corners and bottom edges of the box that traditional fixed ultraviolet lamps cannot reach.

[0014] The bottom of the sputum suction treatment box is provided with bottom legs for support. The setting of the bottom support legs allows the sputum suction treatment box to form an overhead space with the placement plane. On the one hand, it is convenient for ventilation and heat dissipation at the bottom of the equipment, avoiding the heat accumulation generated by the long-term operation of the negative pressure pump body affecting the life of the equipment. On the other hand, it provides an operating space for cleaning and maintenance of the bottom of the box. Medical staff can easily wipe and disinfect the gap between the bottom legs and the bottom of the box to prevent sputum residue or dust accumulation from forming sanitary dead corners.

[0015] One end of the diluent box is provided with a pipe for passing through the sputum suction treatment box to transport the diluent therein. The pipe-through design realizes the automatic delivery of the diluent. When the sputum suction is completed, the liquid in the diluent box can be directly injected into the bottom of the sputum suction treatment box through the pipe, without the need for manual pouring or additional connection of a catheter, thereby reducing the frequency of contact between medical staff and contaminated areas.

[0016] A circular hole for inputting diluent is provided on the top of the diluent tank. The circular hole design provides a convenient filling channel for the diluent tank. The diameter of the circular hole usually matches the mouth of a standard medical syringe or a diluent container. Medical staff can directly add chlorine-containing disinfectant, saline solution and other diluents into the tank through the circular hole without disassembling the tank structure, thereby simplifying the operation process.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, the linkage design of the gears inside the frame and the threaded rods allows the ultraviolet disinfection lamp cover to move along the inner wall of the sputum suction treatment box to form a dynamic disinfection path. When the sputum suction is completed, the gears inside the frame rotate to drive the threaded rods to rotate, driving the ultraviolet disinfection lamp cover to perform a spiral lifting motion on the side of the box, thereby realizing three-dimensional irradiation of areas that are difficult to cover with traditional fixed light sources such as remote corners and corner seams, effectively solving the problem of blind spots in disinfection of fixed ultraviolet disinfection components, ensuring that the bacterial gas overflowing from the sputum is fully inactivated during the rising process, and reducing the risk of contact infection for medical staff.

[0019] 2. In the present invention, the meshing transmission of the half gear and the inner wall rack drives the elliptical ring to slide back and forth along the sliding groove plate, so that the first cleaning strip and the second disinfection strip scrape the residual sputum at the bottom of the box in a Z-shaped trajectory. At the same time, when the gear inside the frame rotates, the bevel gear set and the belt transmission are used to synchronously drive the ultraviolet disinfection lamp cover to move, forming a collaborative cleaning mode of mechanical scraping and ultraviolet disinfection. This design can thoroughly remove the liquid stains and sputum deposits remaining at the bottom of the box after dilution, avoid the disinfection blind spot caused by direct discharge, and the residual bacteria at the bottom of the box after cleaning are significantly reduced, effectively ensuring the safety of the internal environment of the equipment and reducing the risk of infection during operation by medical staff.

[0036] In one embodiment, for the above-mentioned sputum suction treatment box 1, the bottom of the sputum suction treatment box 1 is provided with bottom legs for support.

[0037] In this embodiment, the setting of the bottom support legs allows the sputum suction treatment box 1 to form an overhead space with the placement plane. On the one hand, it facilitates ventilation and heat dissipation at the bottom of the equipment, avoiding the accumulation of heat generated by the long-term operation of the negative pressure pump body 7 affecting the life of the equipment. On the other hand, it provides an operating space for cleaning and maintenance of the bottom of the box.

[0038] In one embodiment, for the diluent tank 6 , one end of the diluent tank 6 is provided with a pipeline for penetrating the sputum suction treatment tank 1 and delivering the diluent thereto.

[0039] In this embodiment, the pipe penetration design realizes the automatic delivery of the diluent. When the suction is completed, the liquid in the diluent tank 6 can be directly injected into the bottom of the suction treatment box 1 through the pipe, without manual pouring or additional connection of the catheter, reducing the frequency of contact between medical staff and contaminated areas.

[0040] In one embodiment, for the diluent tank 6 , a circular hole for inputting the diluent is opened on the top of the diluent tank 6 .

[0041] In this embodiment, the circular hole design provides a convenient filling channel for the diluent box 6. The diameter of the circular hole usually matches the mouth of a standard medical syringe or a diluent container. Medical staff can directly add chlorine-containing disinfectant, saline solution and other diluents into the box through the circular hole without disassembling the box structure, thereby simplifying the operation process.

[0042] The working principle of a multifunctional sputum suction device in the present invention is to insert the sputum suction tube 9 into the interior of the sputum suction treatment box 1 along the connecting block 4, and then start the negative pressure pump body 7 to generate a negative pressure environment inside the sputum suction treatment box 1, and then control the gear 12 in the frame to rotate. During the rotation of the gear 12 in the frame and the rotation of the threaded rod 15, its cross support frame 14 is moved to one end of the sputum suction treatment box 1. When the cross support frame 14 is close to the side of the sputum suction tube 9, the ultraviolet disinfection lamp cover 13 is also near the sputum suction tube 9. When the sputum suction tube 9 is used to suction the patient, the sputum is transported to the bottom of the sputum suction treatment box 1 through the sputum suction tube 9. Since the bottom of the sputum suction tube 9 extends to a position close to the bottom surface of the interior of the sputum suction treatment box 1, the sputum can be reduced from splashing at this time, and the gas with bacteria overflowing in the sputum is irradiated by the ultraviolet disinfection lamp cover 13 when it moves upward inside the sputum suction treatment box 1, thereby killing the gas with bacteria, thereby preventing subsequent residual pathogens from infecting staff, etc.

[0043] After the sputum suction is completed, the negative pressure pump body 7 is closed, and the diluent stored in the diluent tank 6 is used to dilute the sputum inside the sputum suction treatment box 1. Then, when the diluent is transported to the bottom of the sputum suction treatment box 1 by the catheter, the gear 12 in the frame is started to rotate. When the gear 12 in the frame is meshed with the surface of the rack 11 in the frame, the cross support frame 14 slides on the side of the connecting frame 10. During the sliding process of the cross support frame 14, the rotation of the gear 12 in the frame will drive the threaded rod 15 to rotate, and the rotation of the threaded rod 15 will cause the ultraviolet disinfection lamp cover plate 13 to move. When the gear 12 in the frame moves a short distance, the threaded rod 15 rotates to make the ultraviolet disinfection lamp cover 13 move along its surface on the side of the sputum suction treatment box 1, thereby reducing the residual bacteria in the dead corner of the sputum suction treatment box 1. Then, when the threaded rod 15 rotates, it will mesh with the second bevel gear 17 through the first bevel gear 16, so as to use the belt 18 to drive the through rod 20 to rotate. The rotation of the through rod 20 will drive the half gear 27 to rotate. The rotation of the half gear 27 will first mesh with the first inner wall rack 25 to Figure 6 For example, when the half gear 27 is engaged with the first inner wall rack 25, the elliptical ring 24 slides to the right along the bottom of the sliding groove plate 21. When the half gear 27 continues to rotate, the half gear 27 is disengaged from the first inner wall rack 25 and forms a meshing relationship with the second inner wall rack 26. The half gear 27 is engaged with the second inner wall rack 26, thereby driving the elliptical ring 24 to slide to the left. In this way, as the gear 12 inside the frame continues to move, the first cleaning strip 22 and the second disinfection strip 23 on the side of the elliptical ring 24 are just The bottom of the sputum suction treatment box 1 can be completely cleaned to prevent the presence of sputum residue, and during the cleaning process, the ultraviolet disinfection lamp cover 13 moves above the cross support 14, so that the ultraviolet disinfection lamp cover 13 can sterilize the bacteria remaining in the gas inside the sputum suction treatment box 1 as much as possible to avoid bacterial residue. After the cleaning is completed, the diluted sputum is released to the collection point through the liquid outlet valve 3, and then the inside of the sputum suction treatment box 1 is dried by the dryer on the top of the sputum suction treatment box 1 for the next use.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
