Description

Technical Field

[0001] The present invention relates to the technical field of medical device disinfection, and particularly to an ultraviolet medical device disinfection cabinet for medical laboratories. Background Art

[0002] In the daily operation of medical laboratories, the disinfection of medical devices occupies a crucial position. Its disinfection effect is not only directly related to the accuracy of test results but also closely linked to the health and safety of patients. Currently, as a commonly used device for disinfection and sterilization of medical devices, the working principle of an ultraviolet disinfection cabinet is mainly to utilize the ultraviolet rays emitted by ultraviolet lamps. Ultraviolet rays can damage the DNA or RNA structure of microorganisms (such as bacteria, viruses, fungi, etc.), interfering with their physiological processes such as replication and transcription, thereby achieving the purpose of disinfection and sterilization.

[0003] A medical disinfection and protection cabinet disclosed in the existing publication number CN115501356A includes a disinfection cabinet body for disinfecting medical surgical instruments. Inside the disinfection cabinet body, there are ultraviolet disinfection lamps for disinfecting medical surgical instruments. A partition is provided inside the disinfection cabinet body, and multiple ultraviolet disinfection lamps are respectively located at the top inside the disinfection cabinet body and the bottom of the partition. A storage rack for placing medical surgical instruments is provided on the partition, and a support and protection mechanism is provided on the storage rack for protecting it. Although the above technical solution can play an auxiliary support role when disinfecting surgical instruments with a relatively long overall length, and at the same time, when supporting, multiple support members can also alternately support surgical instruments such as intervertebral foraminoscopes.

[0004] However, in the prior art, most traditional ultraviolet disinfection cabinets use ultraviolet lamps in fixed positions for disinfection operations. Since the irradiation range of ultraviolet lamps is relatively fixed, when medical devices are directly placed in the disinfection cabinet, due to the different shapes of the devices themselves and the different placement methods, shadow areas will inevitably be generated, making it difficult for the fixed ultraviolet lamps to irradiate medical devices comprehensively from multiple angles, resulting in disinfection dead spots. In addition, for medical devices with a large volume or special structures, it is difficult for some areas to receive direct ultraviolet irradiation, and the microorganisms hidden in these areas cannot be completely killed, increasing the risk of infection during subsequent use. Moreover, traditional ultraviolet disinfection cabinets have deficiencies in the uniformity of ultraviolet distribution and cannot ensure that ultraviolet rays evenly cover the entire storage space, resulting in uneven quality of disinfected medical devices and significant differences in disinfection effects in different parts, further exacerbating the risk of cross-infection. Therefore, a new type of ultraviolet medical device disinfection cabinet for medical laboratories is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an ultraviolet medical device disinfection cabinet for use in medical laboratories to solve the problem that the irradiation range of the ultraviolet lamp proposed in the above background technology is relatively fixed, making it difficult to fully irradiate the medical devices from multiple angles, resulting in disinfection blind spots.

[0009] Furthermore, an L-shaped support plate is fixed on the support frame, and the input shaft and the transmission shaft are both rotatably connected to the L-shaped support plate and penetrate the L-shaped support plate.

[0010] Furthermore, a rear cover is provided at the rear of the cabinet, and the driving shaft, the second gear, the third gear, the driving shaft and the variable speed motor are all placed in the rear cover.

[0011] Furthermore, the tray is hollowed out and suspended at the center of the front inner ring and the rear inner ring, and the width of the tray is smaller than the inner diameter of the opening.

[0012] Furthermore, a U-shaped frame is fixed inside the front inner ring, protrusions are fixed on both sides of the inner wall of the U-shaped frame, and grooves that match the protrusions are formed on both sides of the tray.

The power unit drives the rear inner ring to rotate, so that the multiple groups of disinfection units distributed in the rear inner ring make circular motions accordingly. The ultraviolet lamps in the disinfection units rotate in a circle with the rear inner ring on the basis of swinging, so that ultraviolet rays can irradiate the medical devices from different angles and directions. Compared with the uneven distribution of ultraviolet rays in traditional disinfection cabinets, this design can ensure that the entire tray area can receive relatively uniform ultraviolet irradiation, avoiding the problem of uneven quality of medical devices after disinfection due to differences in ultraviolet doses.

[0017] 2. By setting up a transmission unit, the transmission unit cooperates with the power unit to realize the compound movement of the disinfection unit. During the whole disinfection process, the ultraviolet lamp follows the circular motion of the rear inner ring while being able to swing along the front and back directions of the tray. This effectively increases the coverage range and angle of ultraviolet rays, and can disinfect medical devices from multiple angles, solving the problem that ultraviolet lamps in traditional ultraviolet disinfection cabinets cannot fully disinfect, and effectively improving the disinfection effect.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] Reference Figures 1 - 3 A UV medical device disinfection cabinet for medical laboratory use includes a cabinet 1, an opening 2 opened at the front end of the cabinet 1, and a sealing door 3 rotatably arranged at the front end of the cabinet 1, the sealing door 3 is used to seal and close the opening 2, and also includes a front inner ring 4 fixed in the cabinet 1, a tray 5 slidably arranged in the front inner ring 4, a rear inner ring 6 rotatably arranged in the cabinet 1, and a plurality of disinfection units 7 arranged in the rear inner ring 6.

[0022] Reference Figures 3 - 6, multiple groups of disinfection units 7 are distributed at the same arc length intervals along the inner edge of the rear inner ring 6, each group of disinfection units 7 includes a support frame 71 fixed to the inner edge of the rear inner ring 6, an output shaft 72 is rotatably provided on the support frame 71, both ends of the output shaft 72 are rotatably connected to the support frame 71 through bearings, a U-shaped frame 73 is fixed on the output shaft 72, a lamp holder 74 is provided on the U-shaped frame 73, and an ultraviolet lamp 75 is installed on the lamp holder 74. It should be noted that the ultraviolet lamp 75 adopts a wireless power supply method, and the wireless power supply is based on the principle of electromagnetic induction. A transmitting coil is installed in the cabinet 1, and the transmitting coil is connected to an external power supply. When the power is turned on, the current passing through the transmitting coil will generate an alternating magnetic field around it, and a receiving coil is correspondingly installed on the ultraviolet lamp 75, and the receiving coil is connected to the circuit system of the ultraviolet lamp 75. The receiving coil on the ultraviolet lamp 75 is located in the cabinet 1 where the transmitting coil is located. The generated alternating magnetic field provides the ultraviolet lamp 75 with the electrical energy required for its operation. The center of the output shaft 72 is rotatably connected to a U-shaped connecting rod 77 via a first rotating shaft 76. The other end of the U-shaped connecting rod 77 is rotatably connected to a connecting arm 79 via a second rotating shaft 78. A transmission unit 8 is provided at the other end of the connecting arm 79. The transmission unit 8 is used to control the rotation of the connecting arm 79, the U-shaped connecting rod 77 and the output shaft 72, so that the ultraviolet lamp 75 swings along the front and rear direction of the tray 5. Since the connecting arm 79 is connected to the U-shaped connecting rod 77 via the second rotating shaft 78, and the U-shaped connecting rod 77 is connected to the output shaft 72 via the first rotating shaft 76, the movement of the connecting arm 79 can be transmitted to the U-shaped connecting rod 77 and the output shaft 72 in turn. The rotation of the output shaft 72 drives the U-shaped frame 73, the lamp holder 74 and the ultraviolet lamp 75 fixed thereon to rotate together, thereby realizing the swing of the ultraviolet lamp 75 along the front and rear direction of the tray 5.

[0023] In traditional disinfection cabinets, since the position of ultraviolet disinfection lamps is fixed, medical devices are prone to shadow areas, resulting in disinfection dead corners. In the present invention, multiple groups of disinfection units 7 are distributed at equal arc length intervals along the inner edge of the rear inner ring 6, and the ultraviolet lamp 75 of each disinfection unit 7 can swing, so that the ultraviolet rays are more evenly distributed in the space where the entire tray 5 is located. In addition, the ultraviolet lamp 75 can swing along the front and rear directions of the tray 5, and can irradiate the medical devices from different angles, effectively reducing the shadow areas caused by the shape and placement of the devices, and greatly reducing the probability of disinfection dead corners. The ultraviolet lamp 75 changes the irradiation direction of the ultraviolet rays by swinging, so that all parts of the medical device have the opportunity to fully receive ultraviolet irradiation, thereby improving the comprehensiveness of disinfection.

[0024] Reference Figures 10 - 11The side where the rear inner ring 6 contacts the front inner ring 4 is rotatably connected through a bearing, and the rear side of the rear inner ring 6 is rotatably connected in the cabinet 1. A power unit 9 is arranged at the rear side of the rear inner ring 6. Specifically, the power unit 9 includes a driving shaft 91 fixed at the rear center of the rear side of the rear inner ring 6. The driving shaft 91 is rotatably connected to the cabinet 1 through a bearing and penetrates to the rear of the cabinet 1. A second gear 92 is fixed on the driving shaft 91. A third gear 93 is meshed with one side of the second gear 92. The third gear 93 is rotatably connected to the rear end face of the cabinet 1 through a driving shaft 94. One end of the driving shaft 94 is rotatably connected to the cabinet 1 through a bearing. A variable speed motor 95 is installed on the rear end face of the cabinet 1 through a bracket. The output end of the variable speed motor 95 is fixedly connected to the other end of the driving shaft 94. A controller 10 is provided on the cabinet 1. The variable speed motor 95 is electrically connected to the controller 10. After the variable speed motor 95 is started, the output end of the variable speed motor 95 drives the driving shaft 94 to rotate. The rotation of the driving shaft 94 causes the third gear 93 connected thereto to start rotating. Since the third gear 93 and the second gear 92 are meshed with each other, the rotation of the third gear 93 will drive the second gear 92 to rotate. The second gear 92 is fixed on the driving shaft 91, thereby driving the driving shaft 91 to rotate. The driving shaft 91 is fixed to the rear inner ring 6, thereby driving the rear inner ring 6 to rotate around the tray 5 with the driving shaft 91 as the center.

[0025] Among them, a rear cover 111 is set at the rear of the cabinet 1, and the driving shaft 91, the second gear 92, the third gear 93, the driving shaft 94 and the variable speed motor 95 are all placed in the rear cover 111. The rear cover 111 is also provided with a transverse ventilation groove for heat dissipation of the variable speed motor 95.

[0026] The power unit 9 drives the rear inner ring 6 to rotate, so that the multiple groups of disinfection units 7 distributed in the rear inner ring 6 make circular motion accordingly. The ultraviolet lamp 75 in the disinfection unit 7 rotates in a circle with the rear inner ring 6 on the basis of swinging, so that the ultraviolet light can be irradiated to the medical device from different angles and directions. For example, for medical devices with irregular shapes, the rotation of the rear inner ring 6 can make the ultraviolet lamp 75 irradiate the device in all directions, effectively eliminating the disinfection dead corners caused by the shape and placement of the device. For larger medical devices, the rotation speed of the rear inner ring 6 can be appropriately reduced to allow the ultraviolet lamp 75 to stay in key positions for a longer time to ensure sufficient ultraviolet radiation dose. Compared with the uneven distribution of ultraviolet rays in traditional disinfection cabinets, this design can ensure that the entire tray 5 area can receive relatively uniform ultraviolet radiation, avoiding the problem of uneven quality of medical devices after disinfection due to differences in ultraviolet radiation doses.

[0027] Specifically, refer to Figures 4 - 6 as well as Figure 9The transmission unit 8 includes an input shaft 81 fixedly connected to the other end of the connecting arm 79, one end of the input shaft 81 is rotatably connected to the support frame 71 through a bearing, a first bevel gear 82 is fixed on the input shaft 81, a second bevel gear 83 is meshed on one side of the first bevel gear 82, a transmission shaft 84 is fixed at the center of the second bevel gear 83, a first gear 85 is fixed on the transmission shaft 84, a gear ring 86 is fixed on the inner edge of the rear side of the front inner ring 4, the gear ring 86 is meshed with the first gear 85, when the rear inner ring 6 is driven by the power unit 9 to sterilize When unit 7 makes a circular motion, due to the rotation of the rear inner ring 6 and the meshing between the gear ring 86 and the first gear 85, the transmission shaft 84 can rotate, and the rotation of the transmission shaft 84 will drive the second bevel gear 83 to rotate synchronously, and the first bevel gear 82 will mesh with the second bevel gear 83, thereby controlling the rotation of the input shaft 81 and transmitting it to the connecting arm 79. Through the connection relationship between the connecting arm 79, the U-shaped connecting rod 77 and the output shaft 72, the output shaft 72 is driven to rotate, so that the ultraviolet lamp 75 swings along the front and rear direction of the tray 5.

[0028] Reference Figure 7 An L-shaped support plate 711 is fixed on the support frame 71. The input shaft 81 and the transmission shaft 84 are rotatably connected to the L-shaped support plate 711 through bearings and penetrate the L-shaped support plate 711. The L-shaped support plate 711 supports the input shaft 81 and the transmission shaft 84, thereby improving the stability of the input shaft 81 and the transmission shaft 84 during rotation.

[0029] The transmission unit 8 cooperates with the power unit 9 to realize the compound movement of the disinfection unit 7. During the entire disinfection process, the ultraviolet lamp 75 can not only follow the rear inner ring 6 to perform circular motion, but also swing along the front and rear directions of the tray 5 at the same time, which effectively increases the coverage range and angle of ultraviolet rays, and can disinfect medical devices from multiple angles, solving the problem that the ultraviolet disinfection lamp in the traditional ultraviolet disinfection cabinet cannot fully disinfect, and effectively improving the disinfection effect.

[0030] Further, see Figures 7 - 8 An electric push rod 731 is installed on the U-shaped frame 73. The output end of the electric push rod 731 is fixedly connected to the lamp holder 74. The electric push rod 731 is electrically connected to the controller 10. When the electric push rod 731 receives the control signal of the controller 10 and starts working, the electric push rod 731 performs telescopic movement. Since the output end of the electric push rod 731 is connected to the lamp holder 74, the lamp holder 74 will be driven to perform linear movement along the telescopic direction of the electric push rod 731, and the ultraviolet lamp 75 will be driven to move accordingly, so as to adjust the distance between the ultraviolet lamp 75 and the medical device to be sterilized, thereby changing the intensity and coverage of the ultraviolet irradiation.

[0031] Furthermore, a spline rod 732 is slidably passed through the U-shaped frame 73, one end of the spline rod 732 is fixedly connected to the lamp holder 74, and an extrusion block 733 is fixed to the other end of the spline rod 732. A spring 734 is provided on the spline rod 732, and both ends of the spring 734 are respectively fixed to the U-shaped frame 73 and the extrusion block 733. Under normal circumstances, the spring 734 is in a certain natural state. When the electric push rod 731 controls the movement of the lamp holder 74, the lamp holder 74 will be subjected to external force. Since the spline rod 732 can slide on the U-shaped frame 73, the lamp holder 74 will be displaced along the axial direction of the spline rod 732, compressing or stretching the spring 734. At the same time, the spline structure on the spline rod 732 can limit the rotation of the lamp holder 74 while ensuring the linear motion of the lamp holder 74, thereby ensuring that the lamp holder 74 and the ultraviolet lamp 75 will not rotate accidentally in the horizontal direction, thereby ensuring the stability of the ultraviolet irradiation direction.

[0032] Reference Figures 12 - 13 The tray 5 is hollowed out and suspended at the center of the front inner ring 4 and the rear inner ring 6. The hollowed-out setting can greatly reduce the shielding of the tray 5 against ultraviolet rays, ensuring that the ultraviolet rays can penetrate to the greatest extent and evenly irradiate the medical devices placed on the tray 5, so that they are within the effective irradiation range of multiple groups of disinfection units 7. The tray 5 is suspended at the center of the front inner ring 4 and the rear inner ring 6, so that it is within the effective irradiation range of multiple groups of disinfection units 7, further improving the comprehensiveness and uniformity of disinfection. The width of the tray 5 is smaller than the inner diameter of the opening 2, which is convenient for the staff to put the medical devices into the tray 5 from the opening 2 or take them out of the tray 5.

[0033] Specifically, a U-shaped frame 411 is fixed in the front inner ring 4, and protrusions 412 are fixed on both sides of the inner wall of the U-shaped frame 411, and grooves 413 that match the protrusions 412 are opened on both sides of the tray 5. When the tray 5 needs to be installed in the front inner ring 4, the staff only needs to align the grooves 413 on both sides of the tray 5 with the protrusions 412 on both sides of the inner wall of the U-shaped frame 411, and then gently push the tray 5, and the protrusions 412 will slide along the grooves 413 until the tray 5 reaches the predetermined position. Due to the close fit between the protrusions 412 and the grooves 413, the tray 5 will not deviate or shake during the sliding process.

[0034] The working principle of an ultraviolet disinfection cabinet for medical instruments used in medical laboratories is as follows: first, the staff opens the sealed door 3 and places the medical instruments on the tray 5 through the opening 2. The tray 5 cooperates with the protrusions 412 on both sides of the inner wall of the U-shaped frame 411 in the front inner ring 4 through the groove 413, and slides in the front inner ring 4. The tray 5 is hollowed out and suspended at the center of the front inner ring 4 and the rear inner ring 6.

[0035] Secondly, the controller 10 on the cabinet 1 sends a signal to start the variable speed motor 95, and the output end of the variable speed motor 95 drives the drive shaft 94 to rotate. The third gear 93 connected to the drive shaft 94 rotates, and through the engagement with the second gear 92, the driving shaft 91 is driven to rotate, so that the rear inner ring 6 rotates around the tray 5. The rear inner ring 6 is rotatably connected to the front inner ring 4 through the bearing to ensure smooth rotation. Then, the rotation of the rear inner ring 6 drives multiple groups of disinfection units 7 to make circular motions. In each group of disinfection units 7, the transmission unit 8 starts to work, and the rear inner ring 6 rotates to make the gear ring 86 mesh with the first gear 85, driving the transmission shaft 84 to rotate, and through the engagement of the second bevel gear 83 with the first bevel gear 82, the input shaft 81 is rotated, and the output shaft 72 is driven to rotate through the connecting arm 79 and the U-shaped connecting rod 77, so that the ultraviolet lamp 75 swings along the front and rear directions of the tray 5. At the same time, the L-shaped support plate 711 on the support frame 71 supports the input shaft 81 and the transmission shaft 84 to ensure stable rotation.

[0036] Finally, during the swinging and circular motion of the ultraviolet lamp 75, the electric push rod 731 on the U-shaped frame 73 can be extended and retracted according to the signal of the controller 10, driving the lamp holder 74 and the ultraviolet lamp 75 to move. While the lamp holder 74 and the ultraviolet lamp 75 move, the spline rod 732 slides on the U-shaped frame 73 and compresses the spring 734 through the squeezing block 733 to adjust the distance between the ultraviolet lamp 75 and the medical device, thereby changing the intensity and range of ultraviolet irradiation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
