Description

Technical Field

[0001] The invention relates to the technical field of medical nursing equipment, in particular to a medical intensive care nursing disinfection device. Background Art

[0002] In modern intensive care, the treatment and care of critically ill patients rely on a variety of advanced medical technologies and equipment. In this process, the medical devices used by patients are easily contaminated due to contact with body fluids, blood and other secretions. If these devices are not disinfected in a timely and effective manner, the risk of cross infection will increase significantly, affecting their reuse. Therefore, ensuring the disinfection of devices has become a key link that cannot be ignored in intensive care.

[0003] The existing patent (Announcement No. CN201810446267.1) is a medical intensive care nursing disinfection device. This patent uses high-temperature heating in an electric water heater and high-temperature spray disinfection. After high-temperature disinfection, the equipment has residual high temperature that is difficult to touch. In addition, the equipment is fixed during the disinfection process, resulting in some difficult-to-reach parts that cannot be thoroughly disinfected, forming a problem of disinfection dead corners. Summary of the invention

[0004] The present application provides a medical intensive care nursing disinfection device, which is used to solve the problem of using high-temperature spray disinfection, resulting in disinfection dead corners and high-temperature residues on equipment after disinfection that are difficult to touch.

[0005] To achieve the above objectives, the present application discloses the following technical solutions:

[0006] A medical intensive care nursing disinfection device comprises a box, a disinfectant liquid containing box, a movable tray and a translation mechanism, wherein the disinfectant liquid containing box is arranged inside the box; the movable tray is used to contain instruments to be disinfected; the movable tray and the disinfectant liquid containing box are arranged opposite to each other in a first direction, and the first direction is perpendicular to the bottom surface of the box; a plurality of ventilation holes are arranged on the movable tray, and the translation mechanism is used to drive the movable tray to translate in the first direction, so that the movable tray moves into or out of the disinfectant liquid containing box.

[0007] In the embodiment of the present application, the mobile tray can be driven by the translation mechanism to move in the first direction perpendicular to the bottom surface of the box, so that the mobile tray can be moved into the disinfectant container and completely immersed in the disinfectant, ensuring that all surfaces of the medical device to be disinfected are covered by the disinfectant, effectively solving the problem of disinfection dead angles caused by the limitation of the fixed position of the device in the traditional disinfection equipment. In addition, by using disinfectant instead of high-temperature disinfection, the device also avoids the problem of high-temperature residue that may occur in high-temperature disinfection. When the disinfection is completed, the mobile tray can be driven by the translation mechanism to rise and move out of the disinfectant container, and the vent hole can be used for draining.

[0008] In addition, through the automated control of the translation mechanism, the mobile tray can be quickly and smoothly moved to the disinfectant container for disinfection, or moved out of the disinfection area for draining. Such automated operation reduces manual intervention, not only improving work efficiency, but also reducing the risk of errors and incomplete disinfection caused by manual operation.

[0009] In some possible embodiments, the box body includes a shell and a box door, the box door includes a first wall plate, a second wall plate and a third wall plate, the first wall plate and the third wall plate are arranged opposite to each other in a first direction, the third wall plate is connected between the first wall plate and the second wall plate, and the second wall plate is used to open and close the opening of the shell; a handle is arranged on the outer wall surface of the second wall plate, the extension direction of the first wall plate is the same as the extension direction of the bottom plate of the shell, the first wall plate is slidably arranged on the inner wall surface of the bottom plate of the shell in the second direction, and the second direction is perpendicular to the first direction; the disinfectant liquid containing box is fixedly arranged on the first wall plate;

[0010] The translation mechanism includes a driving mechanism, a first lead screw, a first sliding nut and a connecting plate. The driving mechanism is used to drive the first lead screw to rotate around the central axis of the first lead screw. One end of the first lead screw is rotatably mounted on the first wall plate, and the other end of the first lead screw is rotatably mounted on the second wall plate. The first sliding nut is mounted on the first lead screw and moves in the first direction with the rotation of the first lead screw; wherein the lead angle of the first lead screw is smaller than the friction angle of the first lead screw, the connecting plate is fixedly mounted on the first sliding nut, and the movable pallet includes a first connecting portion, and the first connecting portion is fixedly connected to the connecting plate.

[0011] In this way, the mobile tray, the disinfectant box and the box door are linked. When the user pulls or pushes the box door, the mobile tray and the disinfectant box will move out or into the shell synchronously. The user no longer needs to perform complicated multi-step operations. The user can complete the placement or removal of the equipment and disinfection preparation work by simply opening and closing the box door, which improves the user experience.

[0012] In addition, the first lead screw can be driven to rotate by the driving mechanism, driving the first sliding nut to move in the first direction, thereby driving the connecting plate and the movable tray to move in the first direction, so that the movable tray can move into or out of the disinfectant containing box.

[0013] In some possible implementations, the driving mechanism includes a first bevel gear, a second bevel gear, a mounting plate, a rotating shaft, a connecting assembly, and a driving device, wherein the first bevel gear is fixedly sleeved on the first lead screw, the mounting plate is fixedly connected to the second wall plate, the rotating shaft is rotatably mounted on the mounting plate, the central axis of the rotating shaft is parallel to the second direction, and the second bevel gear is fixedly sleeved on the rotating shaft.

[0014] The connecting assembly includes a first connecting disk, a second connecting disk, and a connecting shaft. The first connecting disk is fixedly connected to one end of the rotating shaft away from the second bevel gear. A plurality of limiting rods are arranged on a surface of the first connecting disk away from the connecting shaft. The central axis of the limiting rod is parallel to the central axis of the rotating shaft. The central axis of the first connecting disk, the central axis of the second connecting disk, and the central axis of the connecting shaft all coincide with the central axis of the rotating shaft. A plurality of limiting holes are arranged on the second connecting disk. The plurality of limiting holes and the plurality of limiting rods are arranged in one-to-one correspondence. One end of the connecting shaft is fixedly connected to the surface of the second connecting disk away from the first connecting disk.

[0015] The other end of the connecting shaft is fixedly connected to the output shaft of the driving device; the driving device is fixedly mounted on the inner surface of the shell; when the box door is closed, at least a part of the limiting rod is inserted into the limiting hole.

[0016] In this way, when the user pulls the door, the limit rod gradually disengages from the limit hole. As the limit rod disengages, the connection between the first lead screw and the output shaft of the driving device gradually loosens and is finally completely disconnected. During this process, the lead screw automatically disengages from the driving device, and the user can complete this process without performing additional operations. When the user pushes the door to close, the limit rod gradually enters the limit hole. When the door is completely closed, the limit rod is completely inserted into the limit hole, ensuring that the first lead screw is aligned with the output shaft of the driving device, and the driving device can drive the first lead screw to rotate normally. In this process, the user still does not need to perform additional operations to complete this process.

[0017] In some possible implementations, a rounded corner or a chamfer is provided on one end of each limiting rod away from the first connecting plate, so that the limiting rod can be inserted into the limiting hole more smoothly, thereby improving the convenience of operation.

[0018] In some possible embodiments, the translation mechanism also includes a second lead screw, a second sliding nut, a first synchronous wheel, a second synchronous wheel and a synchronous belt, one end of the second lead screw is rotatably mounted on the first wall panel, the other end of the second lead screw is rotatably mounted on the second wall panel, the second sliding nut is mounted on the second lead screw and moves in the first direction with the rotation of the second lead screw; the first synchronous wheel is fixedly mounted on the first lead screw, the second synchronous wheel is fixedly mounted on the second lead screw, the first synchronous wheel is transmission-connected to the second synchronous wheel via a synchronous belt, the connecting plate is also fixedly connected to the second sliding nut, and the movable pallet also includes a second connecting portion, and the second connecting portion is fixedly connected to the connecting plate.

[0019] In this way, the loads applied by the mobile tray and the instruments to be sterilized can be evenly distributed on the two lead screws. In this way, on the one hand, the stress and wear risk of a single lead screw can be reduced, the deformation of the lead screw due to excessive load can be prevented, and the service life of the equipment can be extended; on the other hand, the carrying capacity of the device can be enhanced, so that it can handle heavier medical instruments; on the other hand, the stability of the mobile tray during the entire translation process can also be improved.

[0020] In some possible embodiments, the medical intensive care nursing and disinfection device also includes a limit assembly, which includes a first abutment plate, a second abutment plate, a first pressure sensor, a second pressure sensor and a controller; the first abutment plate and the second abutment plate are arranged on the inner wall surface of the second wall plate, the first abutment plate and the second abutment plate are arranged opposite to each other in the first direction, the second abutment plate is located on the side of the first abutment plate facing the bottom plate of the shell, the first abutment plate is provided with a first pressure sensor on the surface facing the second abutment plate, and the second pressure sensor is provided on the surface of the second abutment plate facing the first abutment plate; at least a portion of the connecting plate is arranged opposite to the first pressure sensor and the second pressure sensor in the first direction; the controller is electrically connected to the first pressure sensor, the second pressure sensor and the driving device.

[0021] In this way, the specific position of the mobile tray can be monitored and controlled in real time by setting the first pressure sensor and the second pressure sensor. When the mobile tray reaches the predetermined position, the pressure sensor detects the corresponding pressure change and transmits the signal to the controller. When the controller analyzes that the pressure reaches the preset value, it controls the drive device to stop, ensuring that each disinfection process can be carried out at the correct position, avoiding the problem of incomplete disinfection caused by inaccurate tray position due to human operation errors, and effectively avoiding excessive resetting of the connecting plate.

[0022] In some possible implementations, the first wall plate is slidably disposed on the inner wall surface of the bottom plate of the housing in the second direction through the cooperation of the slide rail and the slide block. In this way, the sliding is more labor-saving and stable.

[0023] In some possible implementations, the medical intensive care disinfection device further includes a hair dryer, the box door further includes a fourth wall plate, the fourth wall plate is connected between the first wall plate and the third wall plate, and is disposed adjacent to the second wall plate, the hair dryer is disposed on the fourth wall plate, and is located above the disinfectant container, and the fourth wall plate is slidably connected to the inner wall surface of the housing through the cooperation of the slide rail and the slider. In this way, the sterilized equipment can be quickly dried after the sterilization is completed, thereby improving the efficiency of the sterilization process.

[0024] In some possible implementations, an ultraviolet disinfection lamp is provided on the surface of the connection plate facing the disinfectant containing box. In this way, multiple disinfection guarantees can be provided, and the disinfection capability of the medical intensive care disinfection device can be enhanced.

[0025] In some possible implementations, the medical intensive care nursing and disinfection device further includes a door lock structure, which includes a first locking member and a second locking member, wherein the first locking member is disposed on the box door, and the second locking member is disposed on the housing, and the first locking member and the second locking member cooperate to lock the box door to the housing. In this way, the movement of the box door can be effectively prevented, thereby improving the stability of the connection between the rotating shaft and the output shaft of the driving device, and further improving the reliability of the medical intensive care nursing and disinfection device.

The disinfectant container box 2 is fixedly arranged on the first wall panel 121. Exemplarily, the disinfectant container box 2 and the first wall panel 121 can be fixedly connected by screw connection, clamping, welding, etc.

[0049] The translation mechanism 4 includes a driving mechanism 41, a first lead screw 42, a first sliding nut 43 and a connecting plate 44. The driving mechanism 41 is used to drive the first lead screw 42 to rotate around the central axis of the first lead screw 42. One end of the first lead screw 42 is rotatably mounted on the first wall plate 121, and the other end of the first lead screw 42 is rotatably mounted on the second wall plate 122.

When the user pulls or pushes the box door 12, the mobile tray 3 and the disinfectant box 2 will move out of or into the shell 11 synchronously. The user no longer needs to perform complicated multi-step operations, and can complete the placement or removal of equipment and disinfection preparation work by simply opening and closing the box door 12, thereby improving the user experience.

[0051] In addition, the driving mechanism 41 can also drive the first lead screw 42 to rotate, drive the first sliding nut 43 to move in the first direction, and then drive the connecting plate 44 and the movable tray 3 to move in the first direction, so that the movable tray 3 can move into or out of the disinfectant container 2.

[0054] In this way, the loads applied by the mobile tray 3 and the instruments to be sterilized can be evenly distributed on the two lead screws. In this way, on the one hand, the stress and wear risk of a single lead screw can be reduced, the deformation of the lead screw due to excessive load can be prevented, and the service life of the equipment can be extended; on the other hand, the carrying capacity of the device can be enhanced so that it can handle heavier medical instruments; on the other hand, the stability of the mobile tray 3 during the entire translation process can also be improved.

[0055] See also Figure 4 In some embodiments, the medical intensive care disinfection device further includes a blower 6, and the box door 12 further includes a fourth wall plate 124, which is connected between the first wall plate 121 and the third wall plate 123 and is disposed adjacent to the second wall plate 122.

[0056] See also Figure 4In some embodiments, an ultraviolet disinfection lamp 7 is disposed on the surface of the connection plate 44 facing the disinfectant containing box 2. In this way, multiple disinfection guarantees can be provided to enhance the disinfection capability of the medical intensive care disinfection device.

[0057] See also Figure 5 Combined with Figure 6 and Figure 7 In some embodiments, the driving mechanism 41 includes a first bevel gear 411, a second bevel gear 412, a mounting plate 413, a rotating shaft 414, a connecting assembly 415 and a driving device 416. The first bevel gear 411 is fixedly sleeved on the first lead screw 42, the mounting plate 413 is fixedly connected to the second wall plate 122, the rotating shaft 414 is rotatably mounted on the mounting plate 413, the central axis of the rotating shaft 414 is parallel to the second direction, and the second bevel gear 412 is fixedly sleeved on the rotating shaft 414.

[0058] The connecting assembly 415 includes a first connecting disk 4151, a second connecting disk 4152, and a connecting shaft 4153. The first connecting disk 4151 is fixedly connected to one end of the rotating shaft 414 away from the second bevel gear 412. A plurality of limiting rods 4151a are provided on the surface of the first connecting disk 4151 away from the connecting shaft 4153. The central axis of the limiting rod 4151a is parallel to the central axis of the rotating shaft 414. The central axes of the first connecting disk 4151, the second connecting disk 4152, and the connecting shaft 4153 all coincide with the central axis of the rotating shaft 414. A plurality of limiting holes 4152a are provided on the second connecting disk 4152. The plurality of limiting holes 4152a are arranged in a one-to-one correspondence with the plurality of limiting rods 4151a. One end of the connecting shaft 4153 is fixedly connected to the surface of the second connecting disk 4152 away from the first connecting disk 4151.

[0059] The other end of the connecting shaft 4153 is fixedly connected to the output shaft of the driving device 416; the driving device 416 is fixedly mounted on the inner surface of the housing 11; illustratively, the driving device 416 can be a servo motor, of course, the present application is not limited thereto. In other embodiments, the driving device 416 can also be a pneumatic motor or a hydraulic motor. When the door 12 is closed, at least a portion of the limiting rod 4151a is inserted into the limiting hole 4152a.

[0060] In this way, when the user pulls the door 12, the limit rod 4151a gradually disengages from the limit hole 4152a. As the limit rod 4151a disengages, the connection between the first lead screw 42 and the output shaft of the driving device 416 is gradually loosened and finally completely disconnected. In this process, the lead screw automatically disengages from the driving device 416, and the user can complete this process without performing additional operations. When the user pushes the door 12 to close, the limit rod 4151a gradually enters the limit hole 4152a. When the door 12 is completely closed, the limit rod 4151a is completely inserted into the limit hole 4152a, ensuring that the first lead screw 42 is aligned with the output shaft of the driving device 416, and the driving device 416 can normally drive the first lead screw 42 to rotate; in this process, the user still does not need to perform additional operations to complete this process.

[0061] It is understandable that the cooperation between the rotating shaft 414 and the through hole on the mounting plate 413 for mounting the rotating shaft 414 is provided with a certain damping force, so that the rotating shaft 414 is stationary without the action of an external driving force. Exemplarily, damping is achieved by increasing friction between the rotating shaft 414 and the through hole. For example, friction material, such as rubber or other high friction coefficient materials, can be added to the contact surface.

[0062] In some embodiments, a rounded corner or a chamfer is provided on one end of each limiting rod 4151a away from the first connecting plate 4151. In this way, the limiting rod 4151a can be inserted into the limiting hole 4152a more smoothly, thereby improving the convenience of operation.

[0063] See also Figure 8 Combined with Fig. 9 and Fig.10 In some embodiments, the medical intensive care nursing disinfection device further includes a limit assembly 5, which includes a first abutment plate 51, a second abutment plate 52, a first pressure sensor 53, a second pressure sensor 54 and a controller 55; the first abutment plate 51 and the second abutment plate 52 are arranged on the inner wall surface of the second wall plate 122, the first abutment plate 51 and the second abutment plate 52 are arranged opposite to each other in the first direction, the second abutment plate 52 is located on the side of the first abutment plate 51 facing the bottom plate of the shell 11, the first abutment plate 51 is provided with a first pressure sensor 53 on the surface facing the second abutment plate 52, and the second abutment plate 52 is provided with a second pressure sensor 54 on the surface facing the first abutment plate 51; at least a portion of the connecting plate 44 is arranged opposite to the first pressure sensor 53 and the second pressure sensor 54 in the first direction; the controller 55 is electrically connected to the first pressure sensor 53, the second pressure sensor 54 and the driving device 416.

[0064] In this way, the specific position of the movable tray 3 can be monitored and controlled in real time by the first pressure sensor 53 and the second pressure sensor 54. When the movable tray 3 reaches the predetermined position, the pressure sensor detects the corresponding pressure change and transmits the signal to the controller 55. When the controller 55 analyzes that the pressure reaches the preset value, it controls the driving device 416 to stop, ensuring that each disinfection process can be carried out at the correct position, avoiding the problem of incomplete disinfection caused by inaccurate tray position due to human operation errors, and effectively avoiding excessive resetting of the connecting plate 44.
