Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and more specifically, it relates to a waste collection and treatment device for an operating room. Background Art

[0002] In a modern medical environment, the treatment of medical waste generated in an operating room is an extremely important and complex link. A large amount of medical waste is generated during the operation, including surgical instruments, disposable medical supplies, surgical consumables, etc. These wastes may carry harmful substances such as viruses and bacteria and have a high risk of infection. Therefore, these medical wastes cannot be simply crushed and collected during the treatment process, but need to be harmlessly treated with a professional disinfection liquid to ensure the safety and hygiene of the medical environment.

[0003] However, the currently commonly used method of spraying disinfection liquid on the surface in medical waste treatment has obvious defects. This simple surface spraying not only fails to ensure sufficient contact between the liquid and the waste, resulting in an unsatisfactory disinfection effect and reducing the use efficiency of the liquid, but also the excessively sprayed liquid is prone to splashing and leakage, causing secondary pollution. This not only increases the risk of environmental pollution, but also may pose a potential threat to the health of medical staff. At the same time, it also causes waste of the disinfection liquid and increases the operating costs of medical institutions. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] In view of the problems existing in the prior art, the present invention provides a waste collection and treatment device for an operating room to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: A waste collection and treatment device for an operating room, including a driving shaft and a driven shaft, and a plurality of crushing pieces are alternately installed on the driving shaft and the driven shaft;

[0008] The spraying mechanism includes a plurality of outwardly expanding grooves formed in the driving shaft and the driven shaft. Each of the outwardly expanding grooves is fixedly installed with a spraying pipe, and the plurality of spraying pipes are arranged staggered along the plurality of crushing pieces. A storage sleeve is coaxially and slidably installed in each spraying pipe. A storage groove is formed in the storage sleeve, and an internal spring is installed in the storage groove. The other end of the internal spring is connected to a sealing plug, and the sealing plug is slidably connected in the storage groove. A stop ring is coaxially installed on the outer wall of the storage sleeve. When the stop ring fits in the spraying pipe, the sealing plug fits on the side of the storage groove close to the stop ring. A plurality of side grooves are equidistantly formed on the inner wall of the spraying pipe, and the storage sleeve is slidably connected to the plurality of side grooves; and

[0009] The feeding mechanism includes a medicine adding box. Two inner embedding rings are installed on one side of the medicine adding box close to the driving shaft and the driven shaft. Embedding grooves are respectively formed on the driving shaft and the driven shaft, and the two inner embedding rings are respectively rotatably connected in the embedding grooves.

[0010] Preferably, the driving shaft and the driven shaft are respectively rotatably installed on the housing, and a driving wheel and a driven wheel are respectively fixedly connected to the driving shaft and the driven shaft. The diameter of the driving wheel is larger than that of the driven wheel, and the driving wheel meshes with the driven wheel. A speed reducer is fixedly installed on the housing, the driving shaft is connected to the speed reducer, and the speed reducer is installed with a motor. This design ensures the stability of the crushing process and the torque output through the meshing transmission of the driving wheel and the driven wheel.

[0011] Preferably, the feeding mechanism further includes an inflow groove formed in the driving shaft and the driven shaft. One end of the inflow groove communicates with the plurality of outwardly expanding grooves and the spraying pipes, and the other end of the inflow groove communicates with the medicine adding box. This design effectively connects the medicine adding box with the spraying system through the inflow groove, ensuring the continuity and stability of the liquid medicine supply, and at the same time avoiding the leakage of the liquid medicine during the transmission process.

[0012] Preferably, an intermediate plate is slidably installed in the medicine adding box. Two fixing rods are installed on one side of the medicine adding box close to the housing, and the two fixing rods penetrate through the medicine adding box. The intermediate plate is slidably connected to the fixing rods. A medicine adding pipe is communicated and installed on the upper end surface of the medicine adding box. This design realizes the convenient discharge of the liquid medicine storage capacity through the sliding structure of the intermediate plate and the guiding action of the fixing rods, and at the same time the setting of the medicine adding pipe facilitates the replenishment of the liquid medicine.

[0013] Preferably, a pull rod is slidably connected to one side of the medicine adding box away from the inner embedding ring. The pull rod passes through the medicine adding box and is connected to the intermediate plate. A spring is installed on the medicine adding box, and the spring is connected to the pull rod. This design, through the cooperation of the pull rod and the spring, the setting of the spring provides the necessary return force to ensure the reliable operation of the system.

[0014] Preferably, the spraying mechanism further includes a contact head installed on the side of the energy storage sleeve away from the stop ring. A plurality of edge grooves are equidistantly formed on the side wall of the spraying pipe. When the energy storage sleeve slides backward and the contact head moves to the position of the side groove, the side groove communicates with the outside of the spraying pipe. This design realizes the precise control of the spraying timing through the cooperation of the contact head and the edge grooves, ensuring that the liquid medicine is sprayed at the optimal position.

[0015] Preferably, a plurality of inclined spray holes are axially penetrated through the contact head. When the side groove communicates with the outside, the liquid medicine will be sprayed through the inclined spray holes. This design realizes the multi-angle spraying of the liquid medicine through the special arrangement of the inclined spray holes, improving the contact area between the liquid medicine and the waste and the treatment effect.

[0016] Preferably, a telescopic sleeve is coaxially installed on the energy storage sleeve. A plurality of vertical grooves are equidistantly formed on the inner wall of the spraying pipe, and the spraying pipe is slidably connected in the plurality of vertical grooves. The spaces at the upper and lower ends of the connection position between the telescopic sleeve and the energy storage sleeve are in a communicating state. This design ensures the stable operation and precise control of the spraying system through the cooperation of the telescopic sleeve and the vertical grooves.

[0017] Preferably, a limiting disk is coaxially installed in the spraying pipe. A guiding rod is installed on the limiting disk, and a one-way block is slidably installed on the guiding rod. A one-way groove is formed on the spraying pipe. A return spring is installed on the limiting disk, and the other end of the return spring is connected to the one-way block, and the return spring is sleeved on the guiding rod. This design realizes the one-way control of the liquid medicine flow through the cooperation of the limiting disk, the guiding rod and the one-way block.

[0018] Preferably, a plurality of compression springs are installed on the side of the telescopic sleeve close to the limiting disk, and the plurality of compression springs respectively abut against the limiting disk. This design provides the necessary return force for the system through the elastic action of the compression springs, ensuring the smooth operation of the spraying system.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a waste collection and treatment device for an operating room, having the following beneficial effects:

[0021] First, in terms of the waste crushing system, the design of staggered cooperation between the driving shaft and the driven shaft is adopted, and combined with the arrangement of the crushing pieces, an efficient waste crushing function is realized. Through the meshing transmission of the driving wheel and the driven wheel, the stability and continuity of the crushing process are ensured. This design not only improves the crushing efficiency but also ensures that the waste is evenly processed, avoiding large block residues.

[0022] Secondly, in terms of the spraying system, an innovative energy storage spraying mechanism is designed. Through the ingenious coordination of the spraying pipe, energy storage sleeve and sealing plug, precise spraying control is achieved. When the waste comes into contact with the equipment, the spraying mechanism can be automatically triggered to ensure that the liquid medicine is sprayed at the best time and position. This design not only improves the utilization efficiency of the liquid medicine, but also avoids the waste of the liquid medicine and environmental pollution.

[0023] Finally, in terms of the feeding system, automatic replenishment of the medicine liquid is achieved through the coordinated work of the medicine adding box, the embedded ring and the intermediate disk. This design not only ensures the continuity of the medicine liquid supply, but also makes it convenient for operators to replenish and replace the medicine liquid. At the same time, the excellent sealing performance avoids the leakage of the medicine liquid and improves the safety and reliability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Please refer to Figures 1 to 7A waste collection and treatment device for an operating room includes a driving shaft 11 and a driven shaft 12, a plurality of crushing pieces 13 are staggeredly installed on the driving shaft 11 and the driven shaft 12, the driving shaft 11 and the driven shaft 12 are rotatably installed on a housing 41, and a driving wheel 42 and a driven wheel 43 are fixedly connected to the driving shaft 11 and the driven shaft 12, respectively, the diameter of the driving wheel 42 is larger than the diameter of the driven wheel 43, the driving wheel 42 is meshed with the driven wheel 43, a reducer 44 is fixedly installed on the housing 41, the driving shaft 11 is connected to the reducer 44, and the reducer 44 is installed with a motor 45, and a spraying mechanism includes a plurality of outer expansion grooves 2 opened in the driving shaft 11 and the driven shaft 12 1. A medicine spraying pipe 22 is fixedly installed in each outer expansion groove 21, and multiple medicine spraying pipes 22 are staggered along multiple crushing pieces 13. An energy storage sleeve 23 is coaxially slidably installed in each medicine spraying pipe 22. An energy storage groove 24 is provided in the energy storage sleeve 23. An internal spring 25 is installed in the energy storage groove 24. The other end of the internal spring 25 is connected to a sealing plug 26. The sealing plug 26 is slidably connected in the energy storage groove 24. A stop ring 27 is coaxially installed on the outer wall of the energy storage sleeve 23. When the stop ring 27 is attached to the medicine spraying pipe 22, the sealing plug 26 is attached to the side of the energy storage groove 24 close to the stop ring 27. A plurality of side grooves 27 are equidistantly provided on the inner wall of the medicine spraying pipe 22. 8, and the energy storage sleeve 23 is slidably connected to the multiple side grooves 28, the spraying mechanism also includes a contact head 29 installed on the side of the energy storage sleeve 23 away from the stop circle 27, and a plurality of edge grooves 210 are evenly spaced on the side wall of the spraying pipe 22. When the energy storage sleeve 23 slides backward and the contact head 29 moves to the position of the side groove 28, the side groove 28 and the spraying pipe 22 are connected to the outside, and a plurality of inclined spray holes 211 are opened along the axis of the contact head 29. When the side groove 28 is connected to the outside, the liquid medicine will be sprayed out through the inclined spray holes 211. A telescopic sleeve 212 is coaxially installed on the energy storage sleeve 23, and a plurality of vertical grooves 213 are evenly spaced on the inner wall of the spraying pipe 22. It is slidably connected in multiple vertical grooves 213, and the spaces at the upper and lower ends of the connection positions of the telescopic sleeve 212 and the energy storage sleeve 23 are in a connected state. A limit disk 214 is coaxially installed in the spray pipe 22, and a guide rod 215 is installed on the limit disk 214. A one-way block 216 is slidably installed on the guide rod 215. A one-way groove 217 is opened on the spray pipe 22, and a return spring 218 is installed on the limit disk 214. The other end of the return spring 218 is connected to the one-way block 216, and the return spring 218 is sleeved on the guide rod 215. A plurality of compression springs 219 are installed on the side of the telescopic sleeve 212 close to the limit disk 214, and the plurality of compression springs 219 respectively abut against the limit disk 214.

[0036] When the waste in the operating room is crushed, the corresponding waste is first placed in the housing 41, and the motor 45 is started at the same time. The meshing between the driving wheel 42 and the driven wheel 43 drives the multiple crushing pieces 13 on the driving shaft 11 and the driven shaft 12 to rotate synchronously. Since the multiple crushing pieces 13 fit each other, the waste stuck between the multiple crushing pieces 13 will be crushed. When the two fitted crushing pieces 13 cut on the waste, the crushing piece 13 on one side will squeeze the corresponding waste onto the shaft at the other end. Here, squeezing onto the driving shaft 11 is used as an example. When the waste is squeezed onto the driving shaft 11, it will hit the abutment head 29. As the driving shaft 11 and the driven shaft 12 continue to rotate, The waste will continue to be pressed on the contact head 29, causing the contact head 29 to continue to contract. As the contact head 29 is compressed, the energy storage sleeve 23 will slide along the medicine spraying pipe 22. Since the telescopic sleeve 212 is connected to the energy storage sleeve 23, it will move backward synchronously, and the connection position of the two is in a connected state. At this time, the medicine spraying pipe 22 is full of liquid medicine. As the compression spring 219 moves backward, the space in the medicine spraying pipe 22 is reduced. Since the liquid medicine cannot be compressed, the liquid medicine will exert pressure on the sealing plug 26, causing the sealing plug 26 to slide in the opposite direction along the energy storage slot 24, and the internal spring 25 is in a continuously compressed state. When the energy storage sleeve 23 moves to the contact head 29 close to the energy storage slot 24, the sealing plug 26 will slide in the opposite direction along the energy storage slot 24. When the spray tube 22 is close to the position of multiple side grooves 28, the side grooves 28 will connect the inside and outside of the spray tube 22. At this time, the internal spring 25 has stored the compressed energy, and then the internal spring 25 will push the sealing plug 26 to slide along the energy storage groove 24, so that the liquid in the spray tube 22 is sprayed out along the side grooves 28, and is guided to different angles through the edge grooves 210 and the inclined spray holes 211, and then the spraying process is completed. Because the spray tube 22 and the waste are in the closest contact when the contact head 29 is compressed, the sprayed liquid will be effectively mixed with the waste and will not be wasted, thereby improving the utilization rate. After the contact is completed, the contact head 29 returns under the action of the compression spring 219, and this At this time, the sealing plug 26 also abuts against the uppermost end of the energy storage tank 24 and is in a limited state. When the abutting head 29 passes over the side groove 28, the inner and outer sides of the side groove 28 are in a sealed state. At this time, as the compression spring 219 continues to rebound, the interior of the spray pipe 22 will be in a negative pressure state. Since the sealing plug 26 is pressed on the energy storage tank 24, it cannot slide upward. At this time, under the action of the negative pressure, the one-way block 216 releases the seal between it and the one-way groove 217, and the one-way block 216 is pressed on the limiting plate 214 to connect the inflow groove 34 and the spray pipe 22. Under the action of the negative pressure generated by the compression spring 219, the liquid medicine is sucked into the inflow groove 34, so it can be reset, thereby carrying out the next spraying process.

[0037] See also Figure 1 and Figure 7, The feeding mechanism includes a medicine adding tank 31. On one side of the medicine adding tank 31 close to the driving shaft 11 and the driven shaft 12, two embedded rings 32 are installed. Embedded grooves 33 are respectively formed on the driving shaft 11 and the driven shaft 12. The two embedded rings 32 are respectively rotatably connected in the embedded grooves 33. The feeding mechanism further includes an inflow groove 34 formed in the driving shaft 11 and the driven shaft 12. One end of the inflow groove 34 communicates with a plurality of outward expansion grooves 21 and the medicine spraying pipe 22. The other end of the inflow groove 34 communicates with the medicine adding tank 31. A middle disk 35 is slidably installed in the medicine adding tank 31. On one side of the medicine adding tank 31 close to the outer shell 41, two fixing rods 36 are installed, and the two fixing rods 36 penetrate through the medicine adding tank 31. The middle disk 35 is slidably connected to the fixing rods 36. The upper end surface of the medicine adding tank 31 is communicatively installed with a medicine adding pipe 37. On one side of the medicine adding tank 31 away from the embedded ring 32, a pull rod 38 is slidably connected. The pull rod 38 passes through the medicine adding tank 31 and is connected to the middle disk 35. A spring 39 is installed on the medicine adding tank 31. The spring 39 is connected to the pull rod 38.

[0038] Since the embedded ring 32 is rotatably connected in the embedded groove 33, the rotation of the driving shaft 11 and the driven shaft 12 will not affect the seal between the inflow groove 34 and the medicine adding tank 31. As the negative pressure in the medicine spraying pipe 22 sucks the liquid medicine from the medicine adding tank 31, as the liquid medicine flows out, the middle disk 35 slides towards the direction of the embedded ring 32, and the spring 39 also provides a pulling force on the pull rod 38, so that the middle disk 35 has a force moving towards the embedded ring 32, thus meeting the suction requirement. When it is necessary to supplement the liquid medicine, pull the pull rod 38 backward to make the middle disk 35 fit against the rear end and move it away from the medicine adding pipe 37, and then pass the liquid medicine through the medicine adding pipe 37 to supplement the medicine adding tank 31, thus completing the process of supplementing the medicine.
