Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an anti-infection isolation device. Background Art

[0002] The prevention and control of infectious diseases is crucial for safeguarding patient safety and public health. This is especially true in critical care medicine, where patients are at significantly increased risk of infection due to their compromised immune systems and the frequent invasive procedures they undergo. Therefore, infection-preventing isolation devices are essential to prevent the spread of pathogens and reduce the risk of cross-infection.

[0003] At present, isolation cabins are mostly used to physically isolate patients, using sealed cabins to prevent the leakage of contaminated air or cross-infection. In addition, ultraviolet disinfection lamps and chemical spray disinfection are widely used in isolation devices for sterilization and disinfection inside the cabin. However, existing devices still have shortcomings. The main problems are: the contradiction between disinfection efficiency and operational continuity, ultraviolet disinfection requires the cabin to be closed, and the spray disinfectant may leave irritants, both of which affect the continuous treatment of critically ill patients; mobile transportation is inconvenient. For patients who need to be transported or have difficulty in moving, frequent transportation in and out of the isolation cabin is very inconvenient and is more likely to cause secondary injuries. Summary of the Invention

[0004] To address some of the aforementioned issues, the present invention proposes an infection-prevention isolation device. This device utilizes a liftable, adjustable support plate in conjunction with a sealed cabin, facilitating the transport or transfer of patients while isolating them from infection, thereby improving transport efficiency. A circulating air duct within the sealed cabin, combined with a plasma generator, provides contactless disinfection, minimizing impact on patients. Furthermore, an automatically controlled oxygen supply module maintains sufficient oxygen within the sealed cabin, providing an infection-prevention isolation environment for critically ill patients.

[0005] In order to achieve the above-mentioned object, the present invention is realized through the following technical solutions: an infection prevention isolation device, comprising a sealed cabin, the sealed cabin being a rectangular parallelepiped with upper and lower openings, a top cover hingedly connected to the upper right side of the sealed cabin by a hinge rod, the top cover can be flipped and adapted to the upper opening of the sealed cabin by means of the hinge rod, a supporting plate adapted to the bottom opening is correspondingly provided at the bottom of the sealed cabin, the supporting plate can seal the bottom of the sealed cabin, a circulating air duct is installed inside the sealed cabin, a centrifugal fan is installed at the lower side of the circulating air duct, the centrifugal fan cooperates with the circulating air duct to circulate air in the sealed cabin, a through hole is opened on the inner wall of the front end of the sealed cabin and an air outlet pipe is installed, and a filter pipe is connected to the front end of the air outlet pipe;

[0006] Four supporting legs are vertically installed at the four corners of the sealed cabin body, and universal wheels are installed at the bottom of the supporting legs. A base plate is installed on the lower side of the supporting legs to connect the supporting legs. An electric lifting mechanism is installed on the base plate, and a supporting plate is installed on the top of the electric lifting mechanism and the supporting plate is connected to the support plate. The support plate can drive the support plate to rise and fall in the vertical direction through the drive of the electric lifting mechanism: when the support plate rises to the closed position, the sealed cabin body forms an enclosed space; when the support plate drops to the low position, the bottom opening of the sealed cabin body is completely open, forming a barrier-free transfer channel, which is convenient for critically ill patients to be smoothly moved out of the cabin.

[0007] Furthermore, the electric lifting mechanism includes a fixed frame on the base plate and a support plate connected to the support plate, and a scissor-type lifting mechanism composed of a first scissor arm and a second scissor arm hingedly connected to the two, the rear ends of the first scissor arm and the second scissor arm are hinged to the fixed frame and the support plate respectively, and the front end is equipped with a sliding wheel, and the corresponding support plate and the fixed frame are provided with a slide rail groove, and the sliding wheel is constrained by the groove body to prevent dislocation, and the sliding wheel ends on both sides of the second scissor arm are connected by a connecting rod, and a threaded hole is provided in the middle of the connecting rod to fit a screw rod, the front end of the screw rod is fixed to the fixed frame through a bearing, and the rear end of the screw rod is connected to a stepper motor fixed to the fixed frame. When the motor drives the screw rod to rotate, the connecting rod drives the second scissor arms on both sides to slide synchronously along the slide rail groove to realize the lifting and lowering of the entire mechanism;

[0008] An inner ring sealing strip is installed on the side wall of the sealed cabin body that contacts the top cover. The inner ring sealing strip is made of an annular silicone strip structure. A top sealing strip of the same shape and material is installed on the inner surface of the top cover. When the top cover is closed, the two sealing strips further seal the interior of the sealed cabin body.

[0009] The inner surface of the support plate is provided with a bottom sealing strip identical to the top sealing strip. When the support plate and the bottom of the sealed cabin are closed, the bottom sealing strip is attached to the bottom edge of the sealed cabin to improve the sealing performance.

[0010] The circulating air duct is an annular channel with a hollow interior, and side holes are opened on the inner side wall and the lower side wall. A centrifugal fan is installed at the lower right front side of the circulating air duct. The air outlet of the centrifugal fan is connected to the interior of the circulating air duct. The centrifugal fan and the circulating air duct cooperate with the side holes to circulate the air inside the sealed cabin.

[0011] Several plasma generators are installed at equal intervals on the inner wall of the circulating air duct. The plasma generators cooperate with the circulating air duct to sterilize and disinfect the air in the sealed cabin, realizing contactless disinfection.

[0012] A one-way airflow valve is built into the connection between the filter tube and the air outlet pipe to prevent external air from entering. A HEPA high-efficiency air filter layer and an activated carbon layer are set in the filter tube to filter the air discharged from the sealed cabin to prevent pollution to the external environment and avoid cross infection.

[0013] A side bracket is installed on the rear side of the sealed cabin, and an oxygen cylinder is installed on the side bracket. A through hole is opened on the rear side wall of the sealed cabin and is connected to an oxygen supply pipe. The rear end of the oxygen supply pipe is connected to a regulating valve through a connecting pipe. The air inlet of the regulating valve is connected to the air outlet of the oxygen cylinder, and the oxygen in the oxygen cylinder is controlled to flow into the sealed cabin through the regulating valve.

[0014] Furthermore, a control unit is installed on the side bracket, and the control unit can control the opening and closing of the regulating valve. The control unit has a built-in oxygen concentration sensor, and the sensing end of the oxygen concentration sensor is installed on the inner side wall of the sealed cabin. By setting the oxygen concentration threshold received by the control unit, the oxygen concentration sensor detects that when the concentration in the sealed cabin reaches below a certain threshold, the regulating valve is opened to allow oxygen to pass through, and when it reaches above the certain threshold, the regulating valve is closed, thereby realizing automatic regulation of oxygen supply;

[0015] The left and right side walls of the sealed cabin are provided with medical interfaces, which are sealed and isolated by rubber plugs. The medical interfaces include square slots and circular threaded holes, which can be adapted to the interfaces of different medical devices to achieve isolated treatment;

[0016] The upper surface of the sealed cabin body is symmetrically provided with a number of vertical bearing seat holes on both sides and movable keys are installed correspondingly through the bearings. The upper end of the movable key is bent into an L shape. The top cover can be further fixed by rotating and adjusting the position of the upper end of the movable key.

[0017] Beneficial effects of the present invention:

[0018] 1. Compared with the prior art, the present invention cooperates with the sealed cabin body and the electric lifting mechanism, and an electric lifting system consisting of a scissor-type lifting mechanism, a screw and a stepping motor is arranged on the base plate. The screw is driven to rotate to drive the connecting rod to pull the sliding wheel of the second scissor arm to slide synchronously along the slide rail groove, thereby linking the support plate to drive the vertical lifting of the support plate: when the support plate is raised to the closed position, the bottom of the sealed cabin body is completely closed to form an enclosed space; when the support plate is lowered to the low position, the opening at the bottom of the cabin body is completely open to form a barrier-free passage. Combined with the universal wheels at the bottom of the supporting legs, the overall movement of the device and the smooth transfer of patients are realized, which solves the problem of secondary injuries caused by the inconvenience of transportation in the existing isolation cabin.

[0019] 2. Through the synergistic effect of the circulating air duct and the plasma generator, the centrifugal fan drives the air in the cabin to enter from the side holes of the annular circulating air duct and form a circulation. At the same time, the plasma generators equidistantly distributed on the inner wall of the air duct continuously sterilize and disinfect the flowing air without contact. The filter tube connected to the front air outlet pipe has a built-in HEPA high-efficiency filter and an activated carbon layer for double filtration. The one-way airflow valve prevents the backflow of external contaminated air. This ensures that the disinfection process does not require interruption of treatment and there is no chemical residue, ensuring the continuity of treatment for critically ill patients.

[0020] 3. When the top cover is closed, the top sealing strip fits tightly against the inner ring sealing strip of the cabin, and when the support plate is closed, the bottom sealing strip is completely pressed against the edge of the cabin. Combined with the rubber plug of the side wall medical interface, it is sealed and isolated. The oxygen concentration sensor in the rear oxygen supply module monitors the oxygen concentration in the cabin in real time and automatically controls the opening and closing of the regulating valve. Oxygen is replenished into the cabin through the oxygen supply pipe, ensuring a stable oxygen supply in the cabin while maintaining high sealing, providing critically ill patients with a protective environment compatible with safe isolation and continuous treatment.

DETAILED DESCRIPTION

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0031] Example 1

[0032] See Figures 1 to 6 As shown, and based on the contents of this specification, an infection prevention isolation device is proposed, comprising a sealed cabin 1. The sealed cabin 1 is a rectangular parallelepiped structure with upper and lower openings. Made of high-strength transparent polycarbonate, it balances sealing and visibility. A top cover 2 is hingedly connected to the upper right side of the sealed cabin 1 via a hinge rod 201. The top cover 2 can be flipped around the hinge rod 201 to fit the upper opening of the sealed cabin 1, enabling quick opening and closing. A corresponding support plate 3 is provided at the bottom of the sealed cabin 1. The support plate 3 is made of a lightweight aluminum alloy and coated with an antimicrobial coating. It can be vertically raised and lowered by an electric lifting mechanism 6 to close or open the bottom opening of the sealed cabin 1. An annular circulation duct 11 is installed within the sealed cabin 1. Side holes 1101 are evenly distributed along the inner and lower sidewalls of the circulation duct 11. A centrifugal fan 12 is installed at the lower right front side. The outlet of the centrifugal fan 12 is connected to the circulation duct 11, driving the cabin air through the side holes 1101 to form a circulating airflow. Several plasma generators 14 are evenly spaced along the inner wall of the circulation duct 11, using high-frequency discharge technology to generate plasma for contactless sterilization of the flowing air. A through hole is opened on the inner wall of the front end of the sealed cabin 1 and connected to an air outlet pipe 102. The front end of the air outlet pipe 102 is connected to a filter tube 16, which contains a HEPA high-efficiency air filter layer and an activated carbon layer. A one-way airflow valve is built into the connection to prevent backflow of external air, ensuring the cleanliness of the discharged air.

[0033] Four supporting legs 4 are vertically installed at the four corners of the sealed cabin 1. Universal wheels 15 are installed at the bottom of the supporting legs 4 to facilitate the overall movement of the device. The lower side of the supporting legs 4 is connected and fixed through a horizontal base plate 5. An electric lifting mechanism 6 is installed on the base plate 5. The electric lifting mechanism 6 includes a fixing frame 601, a support plate 604 and a scissor-type lifting structure. The scissor-type lifting mechanism is composed of a first scissor arm 602 and a second scissor arm 603 that are hinged. The rear end of the first scissor arm 602 is hinged to the fixed frame 601, and the rear end of the second scissor arm 603 is hinged to the support plate 604. The front ends are both equipped with sliding wheels 608. The corresponding support plates 604 and fixed frames 601 are provided with slide rail grooves 605. The sliding wheels 608 are constrained by the grooves to prevent dislocation. The sliding wheel 608 ends on both sides of the second scissor arm 603 are connected by a connecting rod 609. A threaded hole is provided in the middle of the connecting rod 609 to accommodate a screw rod 606. The front end of the screw rod 606 is fixed to the fixed frame 601 through a bearing, and the rear end is connected to a stepping motor 607. When the stepping motor 607 drives the screw rod 606 to rotate, the connecting rod 609 drives the sliding wheel 608 to slide synchronously along the slide rail groove 605, thereby realizing the extension and retraction of the scissor-type lifting mechanism, thereby linking the support plate 604 to drive the support plate 3 to rise and fall vertically. When the support plate 3 is raised to the closed position, the bottom of the sealed cabin 1 is completely sealed to form a closed space; when the support plate 3 is lowered to the low position, the bottom opening is opened to facilitate the patient to be moved out smoothly.

[0034] The side wall of the inner side of the sealed cabin body 1 in contact with the top cover 2 is installed with an inner ring sealing strip 103 made of an annular silicone material. The inner surface of the top cover 2 is correspondingly provided with a top sealing strip 202 of the same material. When the top cover 2 is closed, the two sealing strips fit tightly together to enhance the sealing performance. The inner surface of the support plate 3 is installed with a bottom sealing strip 301, whose material is consistent with the top sealing strip 202. When the support plate 3 is closed, the bottom sealing strip 301 presses the bottom edge of the sealed cabin body 1 to form a multiple sealing barrier. The rear side of the sealed cabin body 1 is installed with a side bracket 7. The side bracket An oxygen cylinder 8 is fixed on the bracket 7 and connected to the through hole on the rear side wall of the sealed cabin 1 through an oxygen supply pipe 101. The rear end of the oxygen supply pipe 101 is connected to the regulating valve 801 through a connecting pipe 802. The air inlet of the regulating valve 801 is connected to the air outlet of the oxygen cylinder 8. A control unit 9 is also installed on the side bracket 7. The control unit 9 has a built-in oxygen concentration sensor. The sensor sensing end is located on the inner side wall of the sealed cabin 1. It monitors the oxygen concentration in the cabin in real time and automatically controls the opening and closing of the regulating valve 801 according to a preset threshold value to ensure a stable oxygen supply.

[0035] Medical interfaces 10 are provided on the left and right side walls of the sealed cabin 1, including square slots and circular threaded holes, which are suitable for connecting different medical devices. The interfaces are sealed and isolated by rubber plugs.

[0036] The upper surface of the sealed cabin body 1 has bearing seat holes 104 symmetrically opened on both sides. The movable card key 13 is installed through the bearing. The upper end of the movable card key 13 is bent into an L shape. Rotating the movable card key 13 can clamp the edge of the top cover 2 to further fix the position of the top cover 2.

[0037] When using this device, start the stepper motor 607 to drive the screw 606 to rotate, and the pallet 3 is lowered to a low position through the scissor-type lifting mechanism, opening the bottom of the sealed cabin 1, and the patient is smoothly transferred to the pallet 3. Then the stepper motor 607 is reversed, and the pallet 3 is raised to the closed position. The bottom sealing strip 301 presses against the edge of the sealed cabin 1, the top cover 2 is closed and locked by the movable latch 13, and the top sealing strip 202 fits tightly with the inner ring sealing strip 103, forming a completely sealed environment. After starting the centrifugal fan 12, the air in the cabin is driven into the circulating air duct 11. The plasma generator 14 continuously disinfects the air flow in the cabin. The oxygen concentration sensor monitors the oxygen concentration in the cabin in real time. When the concentration is lower than the threshold, the control unit 9 opens the regulating valve 801, and the oxygen in the oxygen cylinder 8 is replenished into the cabin through the oxygen supply pipe 101; when the concentration reaches the standard, the regulating valve 801 is closed. When the patient needs to be transferred, the pallet 3 is lowered to achieve safe patient transfer.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. For those skilled in the art, various modifications and variations can be made to the above embodiments without departing from the principles of the present invention, and these modifications and variations should all fall within the scope of protection of the present invention.
