Description

Technical Field

[0001] The present invention relates to the technical field of isolation and monitoring cabins, and particularly to an isolation and monitoring cabin for critically ill patients. Background Art

[0002] An isolation and monitoring cabin for critically ill patients generally refers to a monitoring space with isolation function provided for critically ill patients in a medical environment. This space has strict requirements in terms of design and function to ensure the life safety and treatment effect of patients. Due to their serious conditions, critically ill patients have very high requirements for the air environment and need to strictly control personnel flow to reduce the risk of cross-infection. The isolation and monitoring cabin provides a relatively sterile treatment environment for patients by taking strict disinfection and isolation measures.

[0003] After retrieval, a Chinese patent with the publication number CN111956827A discloses a medical isolation cabin, which includes an isolation cabin main body, a first exhaust fan, a second exhaust fan and an exhaust gas disinfection device. The bottom of the isolation cabin main body is provided with moving casters. The isolation cabin main body is divided into a buffer area and a negative pressure area by an isolation door arranged inside. An access door is provided on one side of the buffer area away from the negative pressure area. The first exhaust fan is connected to the exhaust gas disinfection device and the buffer area respectively through pipelines. The second exhaust fan is connected to the exhaust gas disinfection device and the negative pressure area respectively through pipelines. The pressure in the negative pressure area is less than the pressure in the buffer area. Ultraviolet lamps and atomizing nozzles are provided inside both the buffer area and the negative pressure area. A first fresh air supply device is provided at the top of the buffer area, and a second fresh air supply device is provided at the top of the negative pressure area. It can solve the problems that the existing isolation cabin has a fixed position, is inconvenient to use, and is prone to cross-infection. However, when this solution is actually used, there are still the following deficiencies:

[0004] When people enter this special medical space with extremely high requirements for a sterile environment, namely the isolation cabin, if only relying on the atomizing nozzles on the upper part for disinfection treatment, this method has significant limitations. Due to the limited spraying range and angle of the atomizing nozzles, it may not be able to comprehensively and evenly cover all parts of the body of the entering personnel, especially areas such as the sides, back and lower limbs of the body. This means that although through the so-called "disinfection" process, there may still be bacteria or other microorganisms that have not been killed remaining on the personnel. Once these potential pollution sources enter the isolation cabin with the personnel, they will pose a serious threat to the originally highly sterile treatment environment.

[0005] Therefore, the present application provides an isolation and monitoring cabin for critically ill patients. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to propose an isolation and monitoring cabin for critically ill patients to solve the problem of incomplete disinfection when people enter.

[0009] Preferably, a guide rail is fixedly installed on the entrance side of the disinfection chamber body, and a sliding door is arranged on the bottom surface of the guide rail.

[0010] Preferably, the disinfection component further includes a push rod penetrating through the side of the pump cylinder, a connecting frame fixedly installed at one end of the push rod located outside the pump cylinder, and a guide groove formed on the inner wall of the pump cylinder. One end of the connecting frame away from the push rod is fixedly connected to the side surface of the sliding door. A piston plate is slidably installed on the inner wall of the pump cylinder. The piston plate is slidably connected to the guide groove through a guide block. A first spring is fixedly installed between the piston plate and the inner wall of the pump cylinder.

[0011] Preferably, one-way valves with opposite flow directions are installed on the inner walls of the liquid supply pipe and the liquid extraction pipe, and a filling pipe is arranged on the top surface of the liquid storage tank.

[0012] Preferably, a fixed shell corresponding to the piston plate is fixedly installed on the outer wall of the pump cylinder, and a limiting structure is arranged inside the fixed shell.

[0013] Preferably, the limiting structure includes a sliding plate slidably installed on the inner wall of the fixed shell, a second spring fixedly installed between the top surface of the sliding plate and the inner top surface of the fixed shell, and a pin rod fixedly installed on the bottom surface of the sliding plate. The pin rod penetrates through the outer wall of the pump cylinder. A pin slot adapted to the pin rod is formed on the outer wall of the piston plate. A foot-operated airbag seat is fixedly installed on the inner bottom surface of the disinfection chamber body, and the foot-operated airbag seat is communicated with the fixed shell through a conduit.

[0014] Preferably, the communication part of the conduit and the fixed shell is arranged at the bottom of the fixed shell, and an inclined surface corresponding to the piston plate is arranged at the bottom end of the pin rod.

[0015] Preferably, the stepping disinfection assembly includes a disinfection box disposed on the inner bottom surface of the slot, a square-shaped groove opened on the inner bottom surface of the disinfection chamber at a position on the side of the slot, and an extraction frame disposed inside the square-shaped groove. The inner wall of the extraction frame is provided with a disinfection plate, and the bottom surface of the disinfection plate is fixedly installed with a plurality of evenly distributed sponge cores.

[0018] Advantages of the present invention:

[0019] 1. For this kind of isolation and monitoring chamber for critically ill patients, by setting the disinfection chamber and the disinfection assembly, and designing the arched branch pipe and the atomizing nozzle, it can ensure that the disinfectant fully covers the body range of medical staff, thereby achieving comprehensive body disinfection. Under the action of one-way valves with opposite flow directions in the liquid extraction pipe and the liquid supply pipe, the opening and closing process of the sliding door can trigger the operation of the liquid pumping cylinder, pumping out the disinfectant in the liquid storage tank and atomizing and spraying it, simplifying the operation process and improving the disinfection efficiency. This comprehensive disinfection method helps to reduce the risk of cross-infection and ensure the safety of medical staff and patients.

[0020] 2. For this kind of isolation and monitoring chamber for critically ill patients, by setting the sliding door and the limiting structure, and designing components such as the piston plate, the push rod, the pin rod and the spring, precise limiting of the piston plate is achieved. When the sliding door is opened, the push rod pushes the piston plate to slide and stretches the spring. At the same time, the pin rod enters the pin slot of the piston plate under the action of the second spring to achieve positioning of the piston plate. Then, the limit can be released by stepping on the foot pedal airbag seat, improving the stability and reliability of the device.

[0021] 3. For this kind of isolation and monitoring chamber for critically ill patients, by setting the slot and the stepping disinfection assembly, the disinfectant stored in the disinfection box wets the disinfection plate under the action of the sponge core, and the soles of the feet of medical staff can be disinfected when stepping on it. In addition, the disinfection plate is connected to the device main body through the extraction frame, which is convenient for replacement and cleaning, ensuring the durability and reliability of the disinfection effect. This sole disinfection method not only improves the hygiene level of medical staff, but also helps to reduce the spread of germs and ensure the safety of patients. Description of the Drawings

[0033] As Figures 1 to 6 shown, an isolation and monitoring chamber for critically ill patients includes a monitoring chamber body 1 and a disinfection chamber body 2. The disinfection chamber body 2 is arranged at the entrance end of the monitoring chamber body 1. A ventilation device 3 is arranged on the side of the monitoring chamber body 1. A guide rail 4 is fixedly installed on the entrance side of the disinfection chamber body 2. A sliding door 5 is arranged on the bottom surface of the guide rail 4. A disinfection component is arranged inside the disinfection chamber body 2. A slot 10 is opened on the inner bottom surface of the disinfection chamber body 2, and a stepped disinfection component is arranged inside the slot 10;

[0034] The disinfection component includes a branch pipe 61 fixedly installed on the inner bottom surface of the disinfection chamber body 2, a plurality of atomizing nozzles 62 arranged at equal intervals on the outer wall of the branch pipe 61, and a liquid pumping cylinder 63 fixedly installed on the inner wall of the disinfection chamber body 2. A liquid storage tank 64 is fixedly installed on the inner wall of the disinfection chamber body 2. A filling pipe 7 is arranged on the top surface of the liquid storage tank 64. A liquid supply pipe 65 is arranged between the outer wall of the liquid pumping cylinder 63 and the end of the branch pipe 61. A liquid suction pipe 66 is arranged between the liquid storage tank 64 and the outer wall of the liquid pumping cylinder 63. One-way valves with opposite flow directions are installed on the inner walls of the liquid supply pipe 65 and the liquid suction pipe 66;

[0035] The disinfection component further includes a push rod 67 penetrating through the side of the liquid pumping cylinder 63, a connecting frame 68 fixedly installed at one end of the push rod 67 located outside the liquid pumping cylinder 63, and a guide groove 69 opened on the inner wall of the liquid pumping cylinder 63. One end of the connecting frame 68 away from the push rod 67 is fixedly connected to the side of the sliding door 5. A piston plate 610 is slidably installed on the inner wall of the liquid pumping cylinder 63. The piston plate 610 is slidably connected to the guide groove 69 through a guide block. A first spring 611 is fixedly installed between the piston plate 610 and the inner wall of the liquid pumping cylinder 63;

[0036] In use, medical staff can first open the sliding door 5. The sliding plate can slide along the guide rail 4 to expose the door opening on the side of the disinfection chamber body 2. At this time, medical staff can enter the disinfection chamber body 2, and then close the sliding plate door 91. Subsequently, medical staff can stand at the position of the slot 10 and below the branch pipe 61. The branch pipe 61 is designed in an arch shape, so the atomizing nozzles 62 on it can cover the body range of medical staff. Under the action of one-way valves with opposite flow directions in the liquid suction pipe 66 and the liquid supply pipe 65, during the opening and closing process of the sliding door 5, the disinfectant in the liquid storage tank 64 can be pumped into the liquid pumping cylinder 63 through the liquid suction pipe 66 by the liquid pumping cylinder 63, and the disinfectant in the liquid pumping cylinder 63 can be pushed into the branch pipe 61 through the liquid supply pipe 65 and sprayed out along the atomizing nozzles 62, so that the bodies of medical staff can be comprehensively disinfected. And under the action of the stepping disinfection component, the soles of the feet of medical staff can also be disinfected, realizing the comprehensive disinfection of the personnel entering the monitoring chamber body 1. The internal temperature of the monitoring chamber body 1 can reach a constant temperature under the action of the ventilation device 3, ensuring that patients are more comfortable inside. The working principles and connection methods of the sliding door 5 and the ventilation device 3 are existing mature technologies and will not be elaborated here too much.

[0037] As Figure 2 , Figure 3 , Figure 4 shown, a fixed shell 8 corresponding to the piston plate 610 is fixedly installed on the outer wall of the liquid pumping cylinder 63, and a limiting structure is arranged inside the fixed shell 8;

[0038] The limiting structure includes a sliding plate 91 slidably installed on the inner wall of the fixed shell 8, a second spring 92 fixedly installed between the top surface of the sliding plate 91 and the inner top surface of the fixed shell 8, and a pin rod 93 fixedly installed on the bottom surface of the sliding plate 91. The pin rod 93 penetrates through the outer wall of the liquid pumping cylinder 63. A pin slot 94 adapted to the pin rod 93 is formed on the outer wall of the piston plate 610. An inclined surface corresponding to the piston plate 610 is arranged at the bottom end of the pin rod 93. A foot pedal airbag seat 95 is fixedly installed on the inner bottom surface of the disinfection chamber body 2. The foot pedal airbag seat 95 is located at the side position of the slot 10. The foot pedal airbag seat 95 is communicated with the fixed shell 8 through a conduit 96. The connection part of the conduit 96 and the fixed shell 8 is arranged at the bottom of the fixed shell 8;

[0039] When the sliding door 5 is opened, the push rod 67 can be driven to slide through the connecting frame 68. During the sliding process of the push rod 67, the piston plate 610 is pushed, so that the piston plate 610 slides along the guide groove 69 and stretches the first spring 611. During the sliding process of the piston plate 610, the pump cylinder 63 is in a negative pressure state. Therefore, the disinfectant liquid in the liquid storage tank 64 can be pumped into the pump cylinder 63 through the liquid suction pipe 66. At the same time, when the piston plate 610 is pushed to a certain position, under the action of the inclined surface at the bottom end of the pin rod 93, the pin rod 93 can enter the pin groove 94 on the outer wall of the piston plate 610 to realize the positioning of the piston plate 610. And under the action of the second spring 92, the slide plate 91 and the pin rod 93 can be pressed tightly to ensure that the position of the piston plate 610 is fixed. As the sliding door 5 closes, the push rod 67 can be reset. After the medical staff stands below the branch pipe 61, the foot-operated airbag seat 95 can be stepped on to be pressed. At this time, the gas in the foot-operated airbag seat 95 can enter the fixed housing 8 through the conduit 96 and push up the slide plate 91, so that the pin rod 93 moves out of the pin groove 94. At this time, under the action of the first spring 611, the piston plate 610 can slide in the reverse direction, and the disinfectant liquid in the pump cylinder 63 can be pushed into the branch pipe 61 through the liquid supply pipe 65. When the medical staff releases the foot after stepping on it, under the action of the second spring 92, the slide plate 91 can slide downward to reset and push the gas in the fixed housing 8 back into the foot-operated airbag seat 95 for reuse.

[0040] As Figure 5 , Figure 6 shown, the stepping disinfection assembly includes a disinfection box 111 arranged on the inner bottom surface of the slot 10, a square-shaped groove 112 opened on the inner bottom surface of the disinfection chamber body 2 at a position on the side of the slot 10, and an extraction frame 113 arranged inside the square-shaped groove 112. The inner wall of the extraction frame 113 is provided with a disinfection plate 114. The disinfection plate 114 is made of a textile material. The top surface of the disinfection plate 114 is provided with a number of convex bumps. The bottom surface of the disinfection plate 114 is fixedly installed with a number of uniformly distributed sponge cores 115. The bottom ends of the sponge cores 115 pass through the top surface of the disinfection box 111 and are located inside the disinfection box 111;

[0041] During the disinfection process, the soles of the medical staff need to step on the disinfection plate 114. The disinfection box 111 stores disinfectant liquid. Under the action of the sponge cores 115, the disinfectant liquid can wet the disinfection plate 114. Therefore, the soles of the medical staff stepping on it can be disinfected. When the disinfection plate 114 needs to be replaced, the extraction frame 113 can be directly lifted to take out the disinfection plate 114 for replacement. After replacement, it can be reset to continue using.

[0042] When the technical solution provided by the present invention is in use, medical staff can first open the sliding door 5. The sliding plate can slide along the guide rail 4 to expose the door opening on the side of the disinfection chamber body 2. At this time, medical staff can enter the disinfection chamber body 2 and then close the sliding plate 91 door. Subsequently, medical staff can stand at the position of the slot 10 and below the branch pipe 61. The branch pipe 61 is designed in an arch shape, so the atomizing nozzles 62 on it can cover the body range of medical staff. Under the action of one-way valves with opposite flow directions in the liquid suction pipe 66 and the liquid supply pipe 65, during the opening and closing process of the sliding door 5, the disinfectant in the liquid storage tank 64 can be pumped into the pump cylinder 63 through the liquid suction pipe 66 by the pump cylinder 63, and the disinfectant in the pump cylinder 63 can be pushed into the branch pipe 61 through the liquid supply pipe 65 and sprayed out along the atomizing nozzles 62, so that the bodies of medical staff can be comprehensively disinfected. And under the action of the stepping disinfection component, the soles of medical staff can also be disinfected, realizing the comprehensive disinfection of the personnel entering the monitoring chamber body 1. The internal temperature of the monitoring chamber body 1 can reach a constant temperature under the action of the ventilation device 3, ensuring that patients are more comfortable inside. The working principles and connection methods of the sliding door 5 and the ventilation device 3 are existing mature technologies and will not be elaborated here;

[0043] When the sliding door 5 is opened, the push rod 67 can be driven to slide through the connecting frame 68. During the sliding process of the push rod 67, the piston plate 610 is pushed, so that the piston plate 610 slides along the guide groove 69 and stretches the first spring 611. During the sliding process of the piston plate 610, the pump cylinder 63 is in a negative pressure state. Therefore, the disinfectant in the liquid storage tank 64 can be pumped into the pump cylinder 63 through the liquid suction pipe 66. At the same time, when the piston plate 610 is pushed to a certain position, under the action of the inclined surface at the bottom end of the pin rod 93, the pin rod 93 can enter the pin groove 94 on the outer wall of the piston plate 610 to position the piston plate 610, and under the action of the second spring 92, the sliding plate 91 and the pin rod 93 can be pressed tightly, ensuring that the position of the piston plate 610 is fixed. As the sliding door 5 closes, the push rod 67 can be reset. After the medical staff stands below the branch pipe 61, the foot pedal airbag seat 95 can be stepped on to be pressed. At this time, the gas in the foot pedal airbag seat 95 can enter the fixed shell 8 through the conduit 96 and lift the sliding plate 91, so that the pin rod 93 moves out of the pin groove 94. At this time, under the action of the first spring 611, the piston plate 610 can slide in the reverse direction and push the disinfectant in the pump cylinder 63 into the branch pipe 61 through the liquid supply pipe 65. When the medical staff releases their feet after stepping on it, under the action of the second spring 92, the sliding plate 91 can slide downward to reset and push the gas in the fixed shell 8 back into the foot pedal airbag seat 95 for reuse;

[0044] During the disinfection process, the soles of the medical staff need to step on the disinfection plate 114. The disinfection box 111 stores disinfectant solution, and under the action of the sponge core 115, the disinfectant solution can wet the disinfection plate 114. Therefore, when the medical staff step on it, the soles of their feet can be disinfected. When the disinfection plate 114 needs to be replaced, the extraction frame 113 can be directly lifted to take out the disinfection plate 114 for replacement. After the replacement is completed, it can be reset to continue using.
