Description

Technical Field

[0001] This invention relates to the field of protective isolation devices, specifically a protective isolation device for a medical device sterilization supply room. Background Technology

[0002] Medical devices used in various hospital departments are typically collected and cleaned by the central supply department. During the collection process, protective isolation devices are usually installed to seal and store used medical devices to prevent the spread of infectious viruses such as tuberculosis into the air, which could pose a safety hazard. These devices also reduce the sensory discomfort caused to personnel by devices with blood or tissue adhering to them. The central supply department requires a certain amount of time to collect medical devices. Prolonged storage during this process can cause adhering bodily fluids and tissues to coagulate, increasing the difficulty of cleaning. After collection, the medical devices need pre-treatment before being disinfected by sterilization equipment. However, common protective isolation devices are not suitable for pre-cleaning the medical devices, making the cleaning and disinfection process in the central supply department quite challenging.

[0013] As a preferred embodiment of the present invention, the adsorption box has an installation groove on its side, and an air pump is installed in the installation groove. The air pump's suction end is connected to the inner cavity of the adsorption box. A filter box is provided at the air pump's outlet end, and an air outlet is provided on the side of the filter box. A protective net is installed in the air outlet. The drive assembly includes a servo motor installed on the side of the isolation box, and the output shaft of the servo motor is connected and fixed to the middle of one of the positioning wheels.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The protective isolation device for the medical device sterilization supply room of the present invention includes a conveying component for transporting medical devices placed in an isolation box. During the transport process, the spraying component performs simple cleaning on the medical devices. Afterward, the devices are transported by the conveying component to the cleaning component for immersion and disinfection, thereby achieving pretreatment of the devices and facilitating the cleaning and disinfection of the devices by the supply room personnel.

[0015] 2. The protective isolation device for the medical device sterilization supply room of the present invention uses an air pump to reduce the air pressure inside the adsorption box. The adsorption holes on the side of the adsorption box draw air from the outside. When a medical device is placed in the placement box, the adsorption holes on the side of the adsorption box draw air to adsorb the medical device outside the positioning net, so that the device moves with the positioning net, which facilitates the transportation and transfer of the device.

[0016] 3. The protective isolation device for the medical device sterilization supply room of the present invention pressurizes the upper part of the inner cavity of the liquid storage tank through the set pressurization component, so that the squeezing plate in the liquid storage tank moves down under the action of air pressure. The squeezing plate squeezes the cleaning liquid in the liquid storage tank into the spray tank through the liquid inlet pipe. The cleaning liquid in the spray tank is sprayed out through the atomizing nozzle to perform simple cleaning on the side of the delivery component, avoiding the solidification of foreign matter such as body fluids and tissues on the outside of the instruments and reducing the difficulty of cleaning the instruments.

[0017] 4. In the protective isolation device of the medical device sterilization supply room of the present invention, when the conveying component transports the instrument to the position of the cleaning box, the adsorption force of the adsorption box disappears and the instrument falls into the cleaning box. The cleaning solution in the cleaning box cleans and soaks the instrument, which facilitates the pretreatment of the instrument and makes it convenient for personnel to clean and disinfect the instrument in the future.

[0018] 5. The protective isolation device for the medical device sterilization supply room of the present invention uses a rotating component to drive the positioning shaft to rotate, which in turn stirs the cleaning liquid in the cleaning tank, so that the cleaning liquid can clean the instruments. A buoyancy plate is rotatably installed at the top of the moving rod, which provides buoyancy to the stirring blade, so that the stirring blade is always close to the surface of the cleaning liquid, which facilitates the stirring blade to stir the cleaning liquid.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-11 This invention provides a technical solution: a protective isolation device for a medical device sterilization supply room, comprising an isolation box 1 and several wheels 2 rotatably mounted on the bottom of the isolation box 1. The wheels 2 are preferably omnidirectional wheels, and brake pedals are provided on the sides of the wheels 2. The wheels 2 facilitate the movement of the isolation box 1, making it convenient for personnel to use the protective isolation device. The isolation box 1 is provided with a conveying component, a spraying component, and a cleaning component. The conveying component is located between the spraying component and the cleaning component. The conveying component is used for transporting medical devices placed in the isolation box 1. During the transport process, the spraying component performs simple cleaning on the medical devices. Afterward, the devices are transported by the conveying component to the cleaning component for immersion and sterilization, realizing the pretreatment of the devices and facilitating the cleaning and sterilization of the devices by the supply room personnel.

[0023] The bottom of the inner cavity of the isolation box is equipped with a placement component, which includes a placement box 4 with an open upper side. The placement box 4 is used to store and collect medical devices collected by medical personnel. Then, the placement box 4 is placed in the isolation box 1, and the isolation box 1 isolates and protects the devices in the placement box 4 to prevent infectious materials in the devices from infecting personnel. At the same time, it reduces the sensory discomfort caused to personnel by medical devices with blood or tissue adhering to them. Preferably, the placement box 4 is equipped with an inclined plate, which makes it easy for the devices placed in the placement box 4 to slide to the middle of the placement box 4 by the inclined surface, and then be transferred by the transfer component.

[0024] The isolation box 1 has a retrieval port on its side corresponding to the placement box 4. Medical personnel can slide the placement box 4 through the retrieval port to move it inside the isolation box 1, making it easy to place the collected medical devices inside the placement box 4. A baffle 41 is rotatably installed on the side of the isolation box 1 to block and seal the retrieval port. The baffle 41 improves the sealing effect of this isolation device during use. Preferably, one end of the baffle 41 is rotatably installed inside the retrieval port via a rotating shaft. A support plate 42 is provided inside the isolation box 1 near the retrieval port. Several elastic elements 43 are provided between the support plate 42 and the isolation box 1. The elastic elements 43 are preferably springs. When placing the placement box 4, pressing the support plate 42 compresses the elastic elements 43 to lower the height of the support plate 42, making it easier to place the placement box 4 above the support plate 42. As the devices in the placement box 4 are gradually transferred away by the conveying component, the weight of the placement box 4 gradually decreases. The elastic elements 43 push the placement box 4 upward through their own elastic support capacity, making it easier for the medical devices placed in the placement box 4 to approach the conveying component, thereby facilitating the conveying component to transfer and transport the devices in the placement box 4.

[0025] The conveying assembly includes an adsorption box 3, and several adsorption holes are provided on the bottom side, the side of the adsorption box 3 facing the spraying assembly, and the top side of the adsorption box 3. Positioning wheels 31 are rotatably installed on the bottom and top of both sides of the adsorption box 3, and an annular belt 32 is sleeved between two positioning wheels 31 on the same side of the adsorption box 3. A positioning net 33 is provided between the two annular belts 32. A driving assembly for driving one of the positioning wheels 31 to rotate is provided on the side of the isolation box 1. Preferably, the driving assembly includes a servo motor 6 installed on the side of the isolation box 1. The output shaft of the servo motor 6 is connected and fixed to the middle of one of the positioning wheels 31. By controlling the operation of the servo motor 6, one of the positioning wheels 31 is driven to rotate, and the positioning wheel 31 drives the annular belt 32 to rotate, so that the positioning net 33 has the conveying capacity.

[0026] An air extraction assembly is provided on the side of the adsorption box 3. An installation groove is opened on the side of the adsorption box 3, and an air extraction pump 34 is installed in the installation groove. The air extraction end of the air extraction pump 34 is connected to the inner cavity of the adsorption box 3. A filter box 35 is provided at the air outlet end of the air extraction pump 34, and an air outlet is provided on the side of the filter box 35. A protective net is installed in the air outlet. The air extraction pump 34 is controlled to reduce the air pressure inside the adsorption box 3. The adsorption holes on the side of the adsorption box 3 extract air from the outside. When a medical device is placed in the placement box 4, the air extraction from the adsorption holes on the side of the adsorption box 3 adsorbs the medical device to the outside of the positioning net 33, so that the device moves with the positioning net 33, which facilitates the transportation and transfer of the device.

[0027] The spraying assembly includes a storage tank 5 installed inside the isolation box 1. The storage tank 5 stores cleaning fluid, which includes, but is not limited to, clean water or disinfectant. A squeezing plate 51 is slidably installed inside the storage tank 5. A guide rod 52 is fixed inside the storage tank 5 and is slidably connected to the squeezing plate 51. When the squeezing plate 51 moves inside the storage tank 5, the guide rod 52 plays a positioning and guiding role to ensure the stability of the squeezing plate 51 during movement. Several spraying boxes 53 are installed on the side of the storage tank 5. Several atomizing nozzles 54 communicating with the inner cavity of the spraying boxes 53 are installed on the side of the spraying boxes 53. The spraying boxes 53 are connected to the inner cavity of the storage tank 5 through a liquid inlet pipe 55. A pressurizing assembly communicating with the top of the inner cavity of the storage tank 5 is installed on the side of the isolation box 1.

[0028] The pressurization component pressurizes the upper part of the inner cavity of the liquid storage tank 5, causing the squeezing plate 51 inside the liquid storage tank 5 to move downward under the action of air pressure. The squeezing plate 51 squeezes the cleaning fluid in the liquid storage tank 5 into the spray tank 53 through the liquid inlet pipe 55. The cleaning fluid in the spray tank 53 is sprayed out through the atomizing nozzle 54 to perform simple cleaning of the instruments on the side of the delivery component, avoiding the solidification of foreign matter such as body fluids and tissues on the outside of the instruments and reducing the difficulty of cleaning the instruments. When the adsorption box 3 is evacuated, the water mist sprayed by the atomizing nozzle 54 is adsorbed by the adsorption box 3 and moves towards the instruments outside the adsorption box 3, which facilitates simple cleaning of foreign matter on the outside of the instruments through water mist. The water mist after cleaning is adsorbed by the adsorption box 3. After the water mist accumulates in the adsorption box 3, it drips into the placement box 4 through the adsorption hole at the bottom of the adsorption box 3, where the placement box 4 collects the dripping water droplets.

[0029] A liquid filling pipe communicating with its inner cavity is provided on the lower side of the liquid storage tank 5. The liquid filling pipe passes through and extends to the outside of the isolation box 1, and a sealing cap is installed at the end of the liquid filling pipe. After removing the sealing cap, cleaning fluid can be added to the liquid storage tank 5 through the liquid filling pipe. A vent pipe 56 communicating with its inner cavity is installed on the top of the liquid storage tank 5. A vent valve 57 is installed on the vent pipe 56. During the process of adding cleaning fluid, the squeezing plate 51 moves upward under the thrust of the cleaning fluid. After opening the vent valve 57, the pressure can be released through the vent pipe 56, which facilitates the upward movement of the squeezing plate 51 and makes it convenient to add cleaning fluid to the liquid storage tank 5.

[0030] The pressurization assembly includes a pressurization cylinder 7 fixed to the outside of the isolation box 1. A compression piston 71 is slidably disposed inside the pressurization cylinder 7. A pushing assembly for driving the compression piston 71 to slide is disposed on the side of the isolation box 1. An air inlet pipe 72 communicating with its inner cavity is installed on the side of the pressurization cylinder 7. The end of the air inlet pipe 72 away from the pressurization cylinder 7 is fixed to the upper part of the side of the liquid storage tank 5 and communicates with the inner cavity of the liquid storage tank 5. When the pushing assembly pushes the compression piston 71 to move inside the pressurization cylinder 7, the compression piston 71 compresses the air in the pressurization cylinder 7 into the air inlet pipe 72. Under the guidance of the air inlet pipe 72, the gas enters the upper part of the inner cavity of the liquid storage tank 5, which facilitates the compression plate 51 to squeeze the cleaning liquid out. An air extraction pipe 74 communicating with its inner cavity is installed on the side of the air inlet pipe 72, and an air extraction valve 75 is installed on the air extraction pipe 74. An air inlet valve 73 is installed on the air inlet pipe 72, and the air inlet valve 73 is located between the air extraction pipe 74 and the liquid storage tank 5.

[0031] It should be noted that both the suction valve 75 and the intake valve 73 are one-way valves. The intake valve 73 is a one-way intake valve, which allows air to enter the liquid storage tank 5 through the intake pipe 72, while the gas in the liquid storage tank 5 cannot be discharged through the intake pipe 72. This prevents the gas delivered to the liquid storage tank 5 from flowing out again when the pushing component drives the squeezing piston 71 to move outward in the pressure cylinder 7. The suction valve 75 is a one-way suction valve. When the pushing component drives the squeezing piston 71 to move outward in the pressure cylinder 7, the pressure cylinder 7 draws air from the outside through the suction pipe 74, ensuring the effective movement of the squeezing piston 71. The suction valve 75 prevents the gas in the pressure cylinder 7 from being discharged through the suction pipe 74 when the pushing component drives the squeezing piston 71 to slide inward in the pressure cylinder 7, ensuring the effective use of the intake pipe 72.

[0032] The driving component includes a crankshaft 61, one end of which is fixedly connected to one of the positioning wheels 31. A connecting rod 62 is rotatably mounted on the other end of the crankshaft 61. The end of the connecting rod 62 away from the crankshaft 61 is hinged to the extrusion piston 71. When the servo motor 6 drives one of the positioning wheels 31 to rotate, the other positioning wheel 31 drives the crankshaft 61 to rotate under the rotation of the annular belt 32. The crankshaft 61 drives the connecting rod 62 to swing, causing the extrusion piston 71 to reciprocate within the pressure cylinder 7, which facilitates the use of the pressure component. In this scheme, the conveying component and the spraying component work synchronously to prevent the cleaning fluid from being wasted. Furthermore, the use of the same driving component reduces its manufacturing cost.

[0033] The cleaning assembly includes a cleaning tank 8 fixed inside an isolation box 1. The top of the cleaning tank 8 is open, and the cleaning tank 8 is filled with cleaning fluid, which includes, but is not limited to, water or disinfectant. One side of the cleaning tank 8 is in contact with the side of the adsorption box 3 that does not have an adsorption port. When the conveying assembly transports the instrument to the position of the cleaning tank 8, the adsorption force of the adsorption box 3 disappears, and the instrument falls into the cleaning tank 8. The cleaning fluid in the cleaning tank 8 cleans and soaks the instrument, which facilitates the pretreatment of the instrument and makes it convenient for personnel to clean and disinfect the instrument later. The top of the isolation box 1 has an operating port, and the side of the isolation box 1 is equipped with a sealing plate 92 that covers and seals the operating port. By moving the sealing plate 92, the operating port can be opened, allowing medical staff to take the instrument out of the cleaning tank 8 through the operating port. A drain pipe connected to the inner cavity of the cleaning tank 8 is installed on the side of the isolation box 1, and a plug is installed in the drain pipe to seal it. After opening the plug, the cleaning fluid in the cleaning tank 8 can be discharged through the drain pipe, which facilitates the replacement of the cleaning fluid in the cleaning tank 8.

[0034] Several positioning shafts 81 are installed on the side of the cleaning tank 8. Positioning ports are opened on the upper part of the side of each positioning shaft 81. A moving rod 83 is slidably installed within the positioning port. Several stirring blades 84 are fixed to the top of the moving rod 83. A rotating assembly is installed inside the isolation tank 1 to drive the positioning shafts 81 to rotate. When the positioning shafts 81 are driven to rotate by the rotating assembly, the stirring blades 84 stir the cleaning fluid in the cleaning tank 8, facilitating the cleaning of the instruments. A buoyancy plate 85 is rotatably installed at the top of the moving rod 83. The buoyancy plate 85 includes, but is not limited to, foam board or plastic board, and provides buoyancy to the stirring blades 84. The stirring blade 84 is always positioned close to the surface of the cleaning fluid, facilitating its agitation. The moving rod 83 is slidably mounted inside the positioning shaft 81, allowing the position of the stirring blade 84 to be adjusted in real time according to the liquid level, thus facilitating the use of the cleaning assembly. In addition, the buoyancy plate 85 also protects the stirring blade 84, preventing the instruments from colliding with it when falling from the conveying assembly and causing deformation or damage. The upper side of the buoyancy plate 85 is provided with a conical part 86, which facilitates the sliding of instruments off the buoyancy plate 85, preventing instruments from falling onto the buoyancy plate 85 and failing to be effectively soaked and cleaned by the cleaning fluid.

[0035] A first helical gear 82 is mounted at the bottom of the positioning shaft 81. The rotating assembly includes a connecting shaft 87. A second helical gear 88 that meshes with the first helical gear 82 is mounted on the side of the connecting shaft 87. A driven wheel 89 is mounted at the end of the connecting shaft 87. A driving wheel 63 is mounted on the side of one of the positioning wheels 31. A transmission belt 64 is sleeved between the driving wheel 63 and the driven wheel 89. When the servo motor 6 drives one of the positioning wheels 31 to rotate, the other positioning wheel 31 drives the driving wheel 63 to rotate under the rotation of the annular belt 32. The driving wheel 63 then drives the driven wheel 89 to rotate through the transmission belt 64, so that the second helical gear 88 on the side of the connecting shaft 87 drives the first helical gear 82 that meshes with it to rotate, which facilitates the positioning shaft 81 to drive the stirring blade 84 to rotate and stir the cleaning liquid through the moving rod 83.

[0036] The cleaning tank 8 is equipped with a collection frame 9. The top of the collection frame 9 is open, and a positioning hole is opened on the side of the collection frame 9 corresponding to the position of the positioning shaft 81. A handle 91 is installed on the upper side of the collection frame 9. After the instrument is detached from the conveying assembly, it is collected by the collection frame 9. Removing the collection frame 9 makes it easy to put and take out the instrument in the cleaning tank 8 and to remove the instrument from the device. When removing the collection frame 9, the moving rod 83 is removed from the positioning shaft 81 to prevent the stirring blade 84 at the end of the moving rod 83 from affecting the removal of the collection frame 9. The positioning hole makes it easy to place the collection frame 9 in the cleaning tank 8 for use. At the same time, the positioning hole makes it easy for the cleaning liquid to flow out or into the collection frame 9.

[0037] The servo motor 6 used in this invention is a commonly used electronic component in the prior art. Its working method and circuit structure are well-known technologies. The servo motor 6 is controlled by setting a switch or a PLC controller. This method is a common technical means used by technicians and will not be described in detail here.
