Description

Technical Field

[0001] The present invention relates to the technical field of infection control, and particularly to an isolation protection device for hospital infection control. Background Art

[0002] The isolation protection device for hospital infection control is a device specifically designed for the hospital environment, aiming to effectively control nosocomial infections. Especially for patients carrying infectious diseases, the isolation mechanism is the core part of the device, usually made of transparent or semi-transparent materials to ensure the isolation of patients from the outside world, while allowing medical staff to observe the patient's condition. There is a sealing structure inside the isolation mechanism to prevent the spread of pathogens through the air, including an air intake mechanism and a sterilization exhaust mechanism. The air intake mechanism is responsible for introducing fresh outside air for the patient to breathe, and the sterilization exhaust mechanism sterilizes the gas exhaled by the patient to prevent the spread of pathogens to the outside world through the air.

[0003] After retrieval, the Chinese patent with the publication number CN114681238A discloses an isolation protection device for hospital infection control, including an isolation chamber body. A plurality of support frames are fixedly connected to the isolation chamber body. Two first connecting plates are fixedly connected to all the support frames located in the middle of the isolation chamber body. Reinforcement structures are provided on the two support frames located at both ends of the isolation chamber body and all the first connecting plates. A second connecting plate is provided on the reinforcement structure, and a fixing structure for fixing the reinforcement structure is provided on the second connecting plate; by setting the support frames, the support frames can support the isolation chamber body. By setting the first connecting plates, it is convenient to install part of the reinforcement structures. By setting the second connecting plate, the fixing structure and the adjusting structure, it is convenient to connect and fix the reinforcement structures, or to release the connection and fixing state of the reinforcement structures, facilitating the disassembly and assembly of the isolation chamber body.

[0004] However, when using the above isolation device, medical staff need to personally assist the patient to enter the isolation chamber and operate outside to ensure the complete closure of the isolation chamber. During this process, medical staff will inevitably come into contact with infectious pathogens, thus increasing the risk of their isolation gowns being contaminated. Once the isolation gown is contaminated, medical staff must perform strict disinfection and sterilization before leaving the isolation environment, or change into a brand-new isolation gown before transferring the patient. This not only may lead to an expansion of the transmission range of pathogens and an increased risk of the leakage of infectious bacteria, but also the entire treatment process is cumbersome and complex, greatly increasing the operation difficulty and time cost. At the same time, the frequent replacement of isolation gowns also causes a great waste of protective materials, posing an additional pressure on the management and allocation of hospital resources.

[0005] Therefore, the present application provides an isolation protection device for hospital infection control to meet the need of reducing the operation of medical staff when using the isolation protection device. Summary of the invention

[0062] Advantages of the present invention:

[0063] 1. For this isolation and protection device for hospital infection control, by setting the slide rail, servo motor and lead screw, patients can independently control the expansion and retraction of the isolation cover through the control device without relying on medical staff, greatly improving the convenience of use. The whole process does not require manual pushing or pulling or manual adjustment, reducing the operation complexity, enabling patients to easily complete the isolation operation. The patients' independent operation of the isolation device reduces direct contact with medical staff, thus reducing the risk of cross-infection. The automated operation also reduces the number of germs that medical staff may carry due to frequent contact with patients, further protecting the safety of medical staff and saving medical resources.

[0064] 2. For this isolation and protection device for hospital infection control, by setting the flexible sealing cover and driving gear, through the meshing of the driving gear and the internal gear ring, it realizes the rotation of the driving sleeve driving the internal gear ring and the fixed disk to rotate, and then through the transmission mechanism, the flexible sealing cover is closely attached to the side wall of the isolation cover, achieving automatic sealing. This process does not require manual operation by medical staff, significantly improving the isolation efficiency. The close attachment of the flexible sealing cover to the side wall of the isolation cover, as well as the adaptive clamping of the sealing strip to the edge of the open end of the isolation cover, jointly ensure the overall sealing of the system, effectively preventing the spread of germs through gaps, providing a safer and more reliable isolation environment for patients. When storing the isolation cover, through the limiting effect of the limiting strip on the movable plate and the design of the torsion spring driving the flexible sealing cover to reset, the automatic restoration of the isolation device is realized.

[0065] 3. For this isolation and protection device for hospital infection control, by setting the rotating shaft, inner cylinder and outer cylinder, it realizes the automatic winding and tensioning of the safety belt, thus realizing the automatic fixation of patients without manual operation by medical staff, significantly improving the fixation efficiency and reducing problems such as unstable fixation caused by improper operation. During the tightening process of the safety belt, it can be adaptively adjusted according to the different tightness required at different body positions under the action of the pawl, avoiding problems such as discomfort caused by being too tight or loss of protection effect caused by being too loose. This design improves the adaptability and comfort of the protection component, enabling patients to maintain a more comfortable state during transportation.

[0066] 4. This isolation protection device for hospital infection control is provided with a traction rope and a guide frame, so that when the safety belt is tightened, the traction rope is loosened and stretched and drives the guide frame to move downward, so that the safety belt can fit more closely to the patient's body; when the safety belt is loosened, the traction rope is tightened and drives the guide frame to move upward, thereby pulling up the safety belt and making it smoothly separate from the patient's body, ensuring that the safety belt can maintain the correct position and state during the tightening and loosening process, and can adapt to the use of patients of different body sizes.

[0082] like Figures 1 to 10As shown, the isolation protection device for hospital infection control includes a bottom plate 1; two slide rails symmetrically fixedly mounted on the top surface of the bottom plate 1 at both ends in the width direction; two side plates 2 fixedly mounted on the two ends of the side wall of the bottom plate 1 along the length direction; a filter 3 arranged on one side plate 2; a negative pressure machine 4 arranged on the other side plate 2; an isolation cover 5 slidably mounted on the slide rails and arranged in a semicircular tube shape with one end closed; ten operating areas 51 evenly arranged on the isolation cover 5; five reinforcement strips 52 evenly fixedly mounted on the isolation cover 5 and penetrating the isolation cover 5; a servo motor 53 fixedly mounted on a side plate 2 near the closed end of the isolation cover 5; a screw rod 54 rotatably mounted between the two side plates 2, and one end passes through the side plate 2 and the servo motor 53 The output end is fixedly connected; a push-pull assembly is arranged on the screw rod 54; a sealing assembly is arranged on the side plate 2; a protection assembly is arranged in the isolation cover 5; a control device is arranged on the bottom plate 1 at a position inside the isolation cover 5; the push-pull assembly includes: a driving sleeve 6, which is sleeved on the screw rod 54 and screwed with the screw rod 54; a sliding sleeve 61, which is slidably sleeved on the driving sleeve 6, and the length is less than the length of the driving sleeve 6; a connecting plate 62, which is fixedly mounted on the sliding sleeve 61, and the other end is fixedly connected to the end of the isolation cover 5 away from the closed end; a limit plate 63, which is fixedly mounted between the two side plates 2 and arranged parallel to the screw rod 54; a guide plate 64, which is fixedly mounted on the driving sleeve 6 at a position extending out of the sliding sleeve 61, and is adapted to the limit plate 63;

[0083] Before use, the push-pull assembly and the isolation cover 5 are both stored in the closed end of the isolation cover 5. The patient can lie on the bottom plate 1 by himself and start the servo motor 53 through the control device. The servo motor 53 rotates and drives the screw rod 54 to rotate. The driving sleeve 6 slides forward along the screw rod 54 under the action of the guide plate 64 and the limit plate 63, and drives the isolation cover 5 to move forward along the slide rail to the other side plate 2 through the sliding sleeve 61 and the connecting plate 62. Under the action of the sealing assembly, the system is sealed as a whole to isolate the patient. When the transfer or isolation is completed, the servo motor 53 is reversed to make the driving sleeve 6 rotate one circle and then move in the opposite direction under the action of the limit plate 63, so that the isolation cover 5 is automatically stored. The whole process does not require the assistance of medical staff. The patient can easily achieve isolation operation by himself, reducing the risk of medical staff carrying germs and causing spread and infection.

[0084] like Figures 2 to 6 as well as Figure 10As shown, the sealing assembly includes: two rotating frames symmetrically and rotatably installed at positions corresponding to the slide rails between the two side plates 2; two flexible sealing covers 7 respectively fixedly installed on the two rotating frames, and one end thereof is fixedly connected to the slide rail; a driving assembly arranged on the driving sleeve 6; a reversing assembly arranged between the two rotating frames; a first sealing strip 78 fixedly installed on the side plate 2 away from the servo motor 53; a second sealing strip 79 fixedly installed on the side plate 2 away from the servo motor 53 and concentrically arranged with the first sealing strip 78; wherein, the first sealing strip 78 and the second sealing strip 79 are adapted to the open end of the isolation cover 5; the driving assembly includes: a driving gear 71 fixedly installed at one end of the driving sleeve 6 away from the servo motor 53; an internal gear ring 72 rotatably installed on the side plate 2 away from the servo motor 53 and adapted to the driving gear 71; a fixed disk 73 fixedly installed at one end of the internal gear ring 72 passing through the side plate 2; a transmission wheel 74 fixedly installed at one end of the rotating frame passing through the side plate 2; a transmission belt 75 sleeved on the fixed disk 73 and the transmission wheel 74; a torsion spring 11 fixedly installed between the internal gear ring 72 and the side plate 2; a relief groove adapted to the guide plate 64 is formed at one end of the limit plate 63 away from the servo motor 53, a movable plate 76 is rotatably installed in the relief groove, and a limit strip 77 is fixedly installed at the bottom of the relief groove;

[0085] When the driving sleeve 6 moves to the other end, it is limited by the side plate 2. At this time, the driving sleeve 6 has a tendency to rotate driven by the lead screw 54. The guide plate 64 can push the movable plate 76 to rotate and make way through the relief groove. The guide plate 64 can realize the rotation of the driving sleeve 6 through the limit plate 63. When the driving sleeve 6 rotates, it slides relative to the sliding sleeve 61, so as to ensure that the isolation cover 5 is always in the closed position. When the driving sleeve 6 moves to the side plate 2, the driving gear 71 can be engaged with the internal gear ring 72. When the driving sleeve 6 rotates, it will drive the internal gear ring 72 and the fixed disk 73 to rotate. The fixed disk 73 drives the transmission wheel 74 to rotate through the transmission belt 75, and then drives the rotating frame to rotate around the axis, so that the flexible sealing cover 7 can be closely attached to the side wall of the isolation cover 5 to achieve the sealing effect. At the same time, the two flexible sealing covers 7 are synchronously sealed through the reversing assembly. At the same time, the first sealing strip 78 and the second sealing strip 79 can be adapted to the edge of the open end of the isolation cover 5, and clamp the isolation cover 5 when moving to the position of the side plate 2 to achieve sealing. It can automatically seal the isolation device after closing the isolation cover 5, without the medical staff closing the zipper or pasting the sealing strip from the outside, simplifying the use operation of the isolation device, making it more simple and convenient to use, and at the same time reducing the contact between the patient and the outside before complete isolation, which can better control the spread of germs. When storing the isolation cover 5, the limit strip 77 makes the movable plate 76 limit the guide plate 64. After the driving gear 71 is separated from the internal gear ring 72, the internal gear ring 72 can drive the flexible sealing cover 7 to reset and automatically restore the isolation device, so that the patient can conveniently leave the isolation cover 5.

[0086] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the protection assembly includes: a rotating shaft 8, which is rotatably mounted between the two side plates 2 and located in the isolation cover 5; a guide bar 81, which is fixedly mounted on the rotating shaft 8; a transmission gear 82, which is fixedly mounted on the transmission wheel 74; a driven gear 83, which is fixedly mounted on one end of the rotating shaft 8 passing through the side plate 2 and meshing with the transmission gear 82; a safety belt 84, one end of which is fixedly mounted on the reinforcement bar 52; a winding assembly, which is arranged on the rotating shaft 8; the winding assembly includes: an inner cylinder 85, which is slidably mounted on the rotating shaft 8; an outer cylinder 86, which is slidably mounted on the inner cylinder 8 5; a mounting groove 87 is provided in the outer cylinder 86; a ratchet 88 is fixedly mounted on the inner cylinder 85 at a position corresponding to the mounting groove 87; a pawl 89 is arranged in the mounting groove 87 and meshes with the ratchet 88; the pawl 89 is radially slidably connected with the mounting groove 87, and an elastic sheet 810 is fixedly mounted between the pawl 89 and the inner side wall of the outer cylinder 86; the reversing assembly includes: a driven wheel 10, fixedly mounted on one end of another rotating frame passing through the side plate 2; a synchronous belt 101, sleeved on one end of the rotating shaft 8 passing through the side plate 2 and the driven wheel 10;

[0087] When the driving sleeve 6 drives the inner gear ring 72 to rotate, the transmission gear 82 can be driven to rotate through the transmission wheel 74, and then the driven gear 83 and the rotating shaft 8 can be driven to rotate. When the rotating shaft 8 rotates, the inner cylinder 85 is driven to rotate, and the ratchet 88 and the ratchet pawl 89 and the outer cylinder 86 are driven to rotate, and then the safety belt 84 is driven to reel up through the outer cylinder 86, so as to tighten the safety belt 84, realize automatic fixation of the patient, and prevent the patient from slipping off the bottom plate 1 during transportation. The automatically tightened safety belt 84 can simplify the operation process of the device and reduce the chance of spreading germs; when tightening the safety belt 84, when the safety belt 84 has been in contact with the body, the resistance generated causes the ratchet 88 to squeeze the ratchet pawl 89 along the The radially sliding compression elastic sheet 810 causes the outer tube 86 and the inner tube 85 to slide relative to each other, thereby achieving different tightness required for different positions of the body, improving the adaptability of the protection component, and avoiding automatic tightening of the safety belt 84, which may cause discomfort to the patient due to excessive tightening, or loss of protection due to excessive loosening. Under the action of the transmission gear 82 and the driven gear 83, the rotating shaft 8 and the rotating frame on one side rotate in opposite directions, and the driven wheel 10 is driven by the synchronous belt 101 to tighten the rotating frame on the other side inward at the same time. When the isolation cover 5 is retracted, the rotating shaft 8 is reversed and reset under the action of the torsion spring 11, and the outer tube 86 automatically loosens the safety belt 84, which can automatically realize and release the protection of the patient.

[0088] like Figures 7 to 9As shown, the length of the outer cylinder 86 is smaller than that of the inner cylinder 85, and one end of the inner cylinder 85 extending out of the outer cylinder 86 is fixedly installed with a limit plate 9, and one end of the reinforcing strip 52 close to the limit plate 9 is fixedly installed with a connecting pipe 91, and one end of the connecting pipe 91 away from the reinforcing strip 52 is slidably installed between the limit plate 9 and the outer cylinder 86, and a guide groove matching the connecting pipe 91 is provided on the reinforcing strip 52, and a traction rope 92 is wound around the inner cylinder 85, and the other end of the traction rope 92 passes through the guide groove and passes through the middle of the reinforcing strip 52, and one end of the traction rope 92 is fixedly installed with a guide frame 93, and the safety belt 84 passes through the guide frame 93 and is fixedly connected to the outer wall of the outer cylinder 86;

[0089] When the isolation cover 5 is folded up, the reinforcing strip 52 drives the connecting tube 91 and drives the inner tube 85 and the isolation cover 5 to slide synchronously along the rotating shaft 8 through the limit plate 9 and the outer tube 86, so that the protection component and the isolation cover 5 can be folded up synchronously. In addition, when the safety belt 84 is tightened, the traction rope 92 wound around the inner tube 85 is loosened and stretched, driving the guide frame 93 to move downward, so that the safety belt 84 can be tightened on the patient's body. When the rotating shaft 8 is reversed to relax the safety belt 84, the inner tube 85 drives the traction rope 92 to tighten, drives the guide frame 93 to move upward, pulls up the safety belt 84, and allows the isolation cover 5 to smoothly leave the patient's body when it is recovered along the slide rail.
