Description

Technical Field

[0001] The present invention relates to the field of disinfection devices, and in particular to a disinfection device for CBCT equipment and a control method thereof. Background Art

[0002] CBCT is the abbreviation of Cone beam CT, which is a cone beam CT imaging device.

[0003] When using the CBCT device, the patient is required to bite the bite bar on the CBCT device. On the one hand, it can assist in positioning and alignment, and on the other hand, it can also reduce the patient's swallowing and talking movements, thereby reducing image artifacts caused by slight head movements. During the examination, the bite bar of the CBCT device will be in direct contact with the patient's mouth, so there is a risk of cross infection. Therefore, each patient must be disinfected after use. Since a CBCT device may receive multiple patients a day, the bite bar must be disassembled and disinfected after each use, or put into a disposable isolation bag for use. Replacing the isolation bag is rather troublesome. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a disinfection device for CBCT equipment and a control method thereof.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a disinfection device for CBCT equipment, comprising a head support table, and further comprising: A connecting rod, the bottom of which is fixedly connected with a rotating plate, the rotating plate is rotatably connected to the mounting hole at the top of the head support platform, and a rotating switching mechanism for driving the rotating plate to rotate is provided at the bottom of the rotating plate, and auxiliary units are symmetrically provided on both sides of the connecting rod; The auxiliary unit comprises: A bite rod, one end of which is connected to the protruding portion of the connecting rod via a rotating assembly; A flip assembly, the flip assembly is used to drive the bite rod to flip and tilt upward; A disinfection sleeve, wherein the disinfection sleeve is sleeved on the surface of the bite rod, and a plurality of disinfection nozzles are arranged inside the disinfection sleeve; A pushing member, the pushing member is used to push the disinfection sleeve to move to a disinfection position; The pushing member may be an electric push rod, which is fixed on the surface of the disinfection sleeve. When in use, the electric push rod is started, and the movable end of the electric push rod extends out and contacts the connecting rod, thereby pushing the disinfection sleeve to move. A water tank is arranged inside the disinfection sleeve, the water tank is connected to the infusion tube through a pipeline, and the disinfection nozzle is connected to the water tank through a pipeline, wherein the infusion tube transports the cleaning liquid into the water tank, and the water tank is connected to a plurality of disinfection nozzles, so that when the cleaning liquid is transported, the disinfection nozzle can spray the cleaning liquid synchronously; Furthermore, the disinfection nozzle can be set to be flip-adjustable, so as to facilitate multi-angle flushing and disinfection; Specifically, when using the CBCT device, the patient is required to bite the bite bar on the CBCT device to reduce the patient's swallowing and talking movements, thereby reducing image artifacts caused by slight head movements; since the CBCT device will be in direct contact with the patient's mouth during the examination, there is a risk of cross infection; The present invention sleeves a disinfection sleeve on the outside of the bite rod. After the detection is completed, the pusher is started to push the disinfection sleeve to the bite position of the bite rod, and the disinfectant is flushed to the bite position through the disinfection nozzle to clean and disinfect. Furthermore, the flip assembly can be started in advance to drive the bite rod to flip so that the bite position of the bite rod is tilted upward. On the one hand, it is helpful to prevent the disinfectant from flowing out during the flushing process. On the other hand, it is also helpful to make the disinfectant droplets on the bite rod fall freely, reducing the water droplets remaining on the bite rod. When the disinfection is completed, the flip assembly can be started to drive the bite rod to reset and restore the bite rod to a horizontal state, thereby ensuring that the bite rod can assist in positioning the patient's head.

[0006] Preferably, the surface of the disinfection sleeve is fixedly connected to a drain pipe, and an electromagnetic valve is fixedly provided at the end of the drain pipe; Among them, by setting up a solenoid valve, when immersion treatment is required, the solenoid valve is closed, and disinfectant is sprayed into the inside of the disinfection sleeve through the disinfection nozzle to immerse and disinfect the bite rod, thereby facilitating disinfection under conditions of a high degree of contamination.

[0007] Preferably, a vibration motor is provided on the surface of the bite rod, and the rotating assembly comprises: Two connecting blocks, the two connecting blocks are fixed at the ends of the bite rod, a gap is arranged between the two connecting blocks, and the protrusion of the connecting rod is arranged in the gap; A rotating shaft, which is a hollow structure, is fixed on two connecting blocks, and is rotatably connected to a connecting rod; Two springs, both of which are sleeved on the surface of the rotating shaft, and the two springs are respectively arranged on both sides of the protruding portion of the connecting rod; Specifically, by setting a vibration motor, the bite rod is driven to vibrate during the immersion and disinfection process of the bite rod, which is beneficial to improve the disinfection effect and also beneficial to remove dirt in irregular positions or gaps on the surface of the bite rod; The use of an ordinary rotating connection structure may affect the vibration effect of the bite rod. Therefore, the present invention provides space for the vibration of the bite rod by setting a gap between the connecting block and the connecting rod. It should be noted that by setting two springs at the hinge position of the bite rod, the bite rod can vibrate in the left and right directions when vibrating.

[0008] In a second aspect, the present invention provides a control method for a disinfection device for CBCT equipment, the control method comprising the following steps: S1. Obtain patient examination time parameters; S2. Compare the patient examination time parameter with the preset time parameter. When the patient examination time parameter is greater than or equal to the preset time, select the immersion disinfection mode. When the patient examination time parameter is less than the preset time, select the flushing disinfection mode. S3. Run the disinfection device according to the disinfection mode; Among them, under normal circumstances, when the patient is examined, the time from the initial alignment and positioning to the later CT examination will be less than the preset time parameter. At this time, the contamination degree of the bite rod is low, and the purpose of disinfection can be achieved by flushing and disinfection. At the same time, it can also reduce the disinfection time and ensure the efficiency of the examination; However, for some elderly people, children or patients with poor control of the head balance bar, it may take a lot of time to position the head before doing CT, which increases the contact time with the bite bar and causes more contamination to the bite bar. At this time, the inspection time will be greater than or equal to the preset time parameter, and the immersion disinfection mode will be selected.

[0009] Normally, the time from the beginning to the end of the patient's bite is the total examination time; However, some patients may accumulate saliva in the oral cavity due to a long positioning time, and need to spit it out during the positioning process, or have symptoms such as retching when biting, which may cause the mouth to separate from the bite bar. Therefore, step S1 includes: Obtaining bite start information detected by the detector; Run the timer to measure time according to the bite information; Obtaining bite stop information detected by the detector; Acquiring examination information of the patient, wherein the examination information at least includes examination completion information and examination in progress information; Pause the timer based on the check in progress message and the bite stopped message; Read the inspection time parameter on the timer according to the bite stop information and the inspection end information; Among them, when the above-mentioned emergency occurs, in order to avoid errors in determining the examination time, the patient's examination information can be retrieved when the patient is out of the bite bar. When the examination information is the examination end information, it means that the patient's examination is over. At this time, the timing can be stopped and the examination time can be read; When the detection information is that the examination is in progress, it means that the patient has encountered the above-mentioned emergency during the occlusion or CT process. At this time, the timing needs to be paused. When the patient has dealt with the emergency, the timing will be started again and the cumulative timing will be performed to avoid the patient's unexpected situation, which will cause the timer to restart and reduce the examination time.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention arranges a disinfection sleeve on the outside of the bite rod, and after the detection is completed, the bite position is cleaned and disinfected by the disinfection sleeve; further, the bite rod can be driven to flip in advance so that the bite position of the bite rod is tilted upward, which is beneficial to avoid the outflow of disinfectant during the flushing process on the one hand, and is also beneficial to allow the disinfectant droplets on the bite rod to fall freely, reducing the residual water droplets on the bite rod; when the disinfection is completed, the bite rod can be driven to reset by starting the flip assembly, so that the bite rod can return to a horizontal state, thereby ensuring that the bite rod can assist in positioning the patient's head.

[0011] 2. Normally, when a patient is examined, the time from the initial alignment and positioning to the later CT examination is short. At this time, the contamination degree of the bite rod is low, and the purpose of disinfection can be achieved by flushing and disinfection. At the same time, it can also reduce the disinfection time and ensure the efficiency of the examination. However, for some elderly people, children or some patients with poor control of the head balance bar, it may take more time to position the head before CT, which increases the contact time with the bite rod and causes more contamination to the bite rod. At this time, the examination time is longer, and the device can automatically select the immersion disinfection mode.

[0012] 3. Some patients may have saliva accumulation in the mouth due to a long positioning time. During the positioning process, they need to spit out saliva, or have symptoms such as dry heaving when biting, which may cause the mouth to separate from the bite bar. The device can automatically identify the above situation, accumulate the inspection time, and avoid incomplete disinfection.

[0013] 4. A bite rod is set up for the patient to bite and assist in positioning the patient's head. After the test is completed, the two auxiliary unit positions are switched by starting the rotary switching mechanism, so that the used bite rod is switched to the disinfection station for disinfection, and the clean bite rod is switched to the auxiliary positioning station for the next patient to be tested. Setting up two bite rods for alternating use is beneficial to shorten the time spent on disinfection and sterilization. The automatic switching is simple to operate, thereby reducing the waiting time for patients. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] like Figures 1 to 8 A disinfection device for CBCT equipment shown includes a head support table 1, and also includes: A connecting rod 3, a rotating plate 25 is fixedly connected to the bottom of the connecting rod 3, the rotating plate 25 is rotatably connected to the mounting hole at the top of the head support platform 1, and a rotating switching mechanism for driving the rotating plate 25 to rotate is provided at the bottom of the rotating plate 25, and auxiliary units are symmetrically provided on both sides of the connecting rod 3; Auxiliary units include: A bite rod 2, one end of which is connected to a protruding portion of a connecting rod 3 via a rotating assembly; A flip assembly, which is used to drive the bite rod 2 to flip and tilt upwards; A disinfection sleeve 4, which is sleeved on the surface of the bite rod 2, and a plurality of disinfection nozzles 5 are arranged inside the disinfection sleeve 4; A push member 6, which is used to push the disinfection sleeve 4 to move to a disinfection position; The push member 6 may be an electric push rod, which is fixed on the surface of the disinfection sleeve 4. When in use, by starting the electric push rod, the movable end of the electric push rod extends and contacts the connecting rod 3, thereby pushing the disinfection sleeve 4 to move. A water tank 23 is provided inside the disinfection sleeve 4, and the water tank 23 is connected to the infusion tube 24 through a pipeline. The infusion tube 24 is a flexible tube, and the length thereof satisfies the movement of the disinfection sleeve 4 and the 180-degree rotation of the connecting rod 3. The disinfection nozzle 5 is connected to the water tank 23 through a pipeline, wherein the infusion tube 24 transports the cleaning liquid in the external liquid supply device into the water tank 23. The water tank 23 is connected to a plurality of disinfection nozzles 5, so that when the cleaning liquid is transported, the disinfection nozzle 5 can spray out the cleaning liquid synchronously; Furthermore, the disinfection nozzle 5 can be set to be flip-adjustable, so as to facilitate multi-angle flushing and disinfection; Specifically, when using the CBCT device, the patient is required to bite the bite bar on the CBCT device to reduce the patient's swallowing and talking movements, thereby reducing image artifacts caused by slight head movements; since the CBCT device will be in direct contact with the patient's mouth during the examination, there is a risk of cross infection; The present invention provides a bite rod 2 for the patient to bite and assist the patient's head in positioning. After the detection is completed, the positions of the two auxiliary units are switched by starting the rotary switching mechanism, so that the used bite rod 2 is switched to the disinfection station for disinfection, and the clean bite rod 2 is switched to the auxiliary positioning station for the next patient to be detected. The two bite rods 2 are set to be switched and used in turn, which is conducive to shortening the time spent on disinfection and sterilization. The automatic switching is adopted, and the operation is simple, thereby reducing the waiting time of the patient. A disinfection sleeve 4 is sleeved on the outer side of the bite rod 2. When the used bite rod 2 is switched to the disinfection station, the pusher 6 is started to push the disinfection sleeve 4 to the bite position of the bite rod 2, and the disinfectant is flushed to the bite position through the disinfection nozzle 5 to clean and disinfect it. Furthermore, before disinfection, the flip assembly can be started in advance to drive the bite rod 2 to flip so that the bite position of the bite rod 2 is tilted upward. On the one hand, it is helpful to prevent the disinfectant from flowing out during the flushing process. On the other hand, it is also helpful to make the disinfectant droplets on the bite rod 2 fall freely, reducing the water droplets remaining on the bite rod 2. When the disinfection is completed, the flip assembly can be started to drive the bite rod 2 to reset and restore the bite rod 2 to a horizontal state, thereby ensuring that the bite rod 2 can assist in positioning the patient's head.

[0026] As an optional embodiment of the present invention, the rotation switching mechanism includes an outer gear ring 26 and a mounting frame, the outer gear ring 26 is fixedly connected to the bottom of the rotating plate 25, the mounting frame is fixedly connected to the inner wall of the head support platform 1, and a driving motor 27 is fixedly installed on the mounting frame. The output shaft end of the driving motor 27 is fixedly connected to a gear 28, and the gear 28 is meshed with the outer gear ring 26; when working, by starting the driving motor 27, the driving motor 27 is a stepping motor that can rotate in the opposite direction, and the output shaft of the driving motor 27 will drive the gear 28 to rotate, and the rotating gear 28 drives the outer gear ring 26 connected to the bottom of the rotating plate 25 to rotate, thereby driving the connecting rod 3 to rotate 180 degrees, and the auxiliary units on both sides of the connecting rod 3 are switched, and the auxiliary units after disinfection are switched to the auxiliary positioning station for the patient to bite, and the auxiliary units after use are switched to the disinfection station for disinfection and sterilization. When the driving motor 27 rotates in the opposite direction, the rotating plate 25 connected to the connecting rod 3 is driven to rotate 180 degrees in the opposite direction to reset with the help of the outer gear ring 26, and the switching of the two auxiliary units is realized again.

[0027] Normally, the patient's test time is short, and the test can be completed in about three minutes, which causes less contamination to the bite bar 2, and can be directly disinfected by flushing; However, for some elderly people, children or patients with poor head balance control ability, it may take a long time to position the head before doing CT, which increases the contact time with the bite rod 2, resulting in more contamination of the bite rod 2. At this time, the bite may need to be immersed and disinfected. Therefore, the present invention proposes a further embodiment, the surface of the disinfection sleeve 4 is fixedly connected with a drain pipe 7, and the end of the drain pipe 7 is fixedly provided with a solenoid valve 8. The drain pipe 7 is a flexible pipe, and the length meets the movement of the disinfection sleeve 4 and the 180-degree rotation of the connecting rod 3; Among them, by setting the solenoid valve 8, when immersion treatment is required, the solenoid valve 8 is closed, and disinfectant is sprayed into the inside of the disinfection sleeve 4 through the disinfection nozzle 5 to immerse and disinfect the bite rod 2, thereby facilitating disinfection under conditions of high contamination levels.

[0028] In order to further ensure the disinfection effect during the soaking treatment, the present invention proposes a further embodiment, in which a vibration motor 9 is provided on the surface of the bite rod 2, and the rotating assembly includes: Two connecting blocks 10, the two connecting blocks 10 are fixed to the ends of the bite rod 2, a gap is provided between the two connecting blocks 10, and the protrusion of the connecting rod 3 is provided in the gap; A rotating shaft 11, which is a hollow structure and is fixed on two connecting blocks 10. The rotating shaft 11 is rotatably connected to the connecting rod 3; Two springs 12, both springs 12 are sleeved on the surface of the rotating shaft 11, and the two springs 12 are respectively arranged on both sides of the protruding portion of the connecting rod 3; Specifically, by providing a vibration motor 9, the bite rod 2 is driven to vibrate during the process of immersion and disinfection of the bite rod 2. Under the action of vibration, the disinfection effect is improved, and the dirt in the irregular position or gap on the surface of the bite rod 2 is also removed. The use of an ordinary rotating connection structure may affect the vibration effect of the bite rod 2. Therefore, the present invention provides a gap between the connecting block 10 and the connecting rod 3 to provide a space for the bite rod 2 to vibrate. It should be noted that by arranging two springs 12 at the hinge position of the bite rod 2, the bite rod 2 can vibrate in the left and right directions when vibrating, thereby facilitating the discharge of the disinfectant. Furthermore, an electric heating wire can be arranged inside the disinfection sleeve 4 on the CBCT device to heat the inside of the disinfection space so that the residual disinfectant is heated to generate steam. On the one hand, the high-temperature steam is used to further achieve high-temperature sterilization and disinfection on the surface of the bite rod 2, and on the other hand, the bite rod 2 is dried, further accelerating the drying speed.

[0029] As a further embodiment of the present invention, the flip assembly includes: A stepper motor 13, the stepper motor 13 is fixed on the connecting rod 3; A driving shaft 14, the driving shaft 14 is fixed to the output shaft of the stepping motor 13, the driving shaft 14 is inserted into the end of the rotating shaft 11, and a slot 15 is opened on the surface of the driving shaft 14; The card strip 16 is fixed on the inner wall of the rotating shaft 11, and the slot 15 is adapted to the card strip 16. When the disinfection sleeve 4 vibrates left and right, the card strip 16 slides in the slot 15; Specifically, before disinfection, the stepper motor 13 is started first, and the stepper motor 13 drives the driving shaft 14 to rotate. Under the connection between the slot 15 and the clamping strip 16, the driving shaft 14 can drive the rotating shaft 11, the connecting block 10, and the bite rod 2 to move as a whole; Since the driving shaft 14 is inserted into the rotating shaft 11 , the rotating shaft 11 can slide outside the driving shaft 14 during the vibration of the bite rod 2 , thereby facilitating the stepping motor 13 from being squeezed and damaged.

[0030] Since the bite bar 2 has the function of assisting the patient's head positioning and alignment, when the patient bites the bite bar 2, if the position is limited only by the spring 12, the position of the bite bar 2 may be offset, affecting the quality of the CT film. Therefore, as a further embodiment of the present invention, a positioning component is further provided at the end of the bite bar 2. The positioning component is used to position the bite bar 2 in the left and right directions when the bite bar 2 returns to a horizontal state. The positioning component includes: A thread groove 17, wherein the thread groove 17 is provided on the surface of the driving shaft 14; A push rod 18, the push rod 18 is threadedly connected to the thread groove 17, and an end of the push rod 18 is slidably connected to the connecting rod 3; A blocking pin 19, which is disposed between one of the connecting blocks 10 and a protruding portion of the connecting rod 3; A blocking plate 20, which is disposed at the bottom of the bite rod 2 and is fixed to the connecting rod 3; Specifically, the present invention positions the bite rod 2 in a horizontal state by arranging the push rod 18 and the blocking pin 19 to ensure the stability of the bite rod 2 in a horizontal state; After the vibration is completed, during the process of flipping and resetting the bite rod 2, the drive shaft 14 will rotate. Since one end of the push rod 18 is slidably connected to the connecting rod 3, one end of the push rod 18 can be limited. When the drive shaft 14 rotates, under the action of the threaded connection between the push rod 18 and the drive shaft 14, the drive shaft 14 can drive the push rod 18 to move away from the connecting block 10, canceling the squeezing positioning of the connecting block 10, thereby providing sufficient vibration space for the connecting block 10 and the bite rod 2 after flipping to the upward state; After the vibration is completed, during the resetting process of the bite rod 2, the push rod 18 is gradually reset to reposition the connecting block 10, thereby ensuring the stable state of the bite rod 2; Furthermore, by providing the blocking plate 20 , the bottom of the bite rod 2 can be supported. When the patient bites the bite rod 2 , the bottom of the bite rod 2 is supported, which is helpful to reduce the limiting pressure of the stepper motor 13 .

[0031] Normally, when a patient is examined, the time from the initial alignment and positioning to the later CT examination is less than the preset time parameter. At this time, the contamination degree of the bite bar 2 is low, and the purpose of disinfection can be achieved by flushing and disinfection. At the same time, the disinfection time can be reduced to ensure the inspection efficiency. However, for some elderly people, children or patients with poor head balance control ability, it may take a long time to position the head before doing CT, thereby increasing the contact time with the bite rod 2, resulting in more contamination of the bite rod 2. At this time, the inspection time will be greater than or equal to the preset time parameter, and then the immersion disinfection mode is selected. Therefore, as a further embodiment of the present invention, a detector 21 is installed on the bite rod 2, and the detector 21 is used to identify whether the patient bites the bite rod 2. A timer is also provided on the head support platform 1, and the timer is used to time the patient's bite time; Specifically, the detector 21 may be a pressure sensor, which is set at the biting position of the bite bar 2. When the patient bites the bite bar 2, the pressure sensor will be squeezed, thereby confirming the start time of the patient's test. At this time, the timer can be used to count. When the patient does not bite, it means that the test is over, so that the patient's test time can be calculated; The timer may use a timing module inside a computer terminal, or a physical timing device may be installed on the head support platform 1 .

[0032] like Fig. 9 A control method for a disinfection device for a CBCT device is shown, and the control method comprises the following steps: S1. Obtain patient examination time parameters; S2. Compare the patient examination time parameter with the preset time parameter. When the patient examination time parameter is greater than or equal to the preset time, select the immersion disinfection mode. When the patient examination time parameter is less than the preset time, select the flushing disinfection mode. S3. Run the disinfection device according to the disinfection mode; In general, when a patient is examined, the time from the initial alignment and positioning to the later CT examination is less than the preset time parameter. At this time, the contamination degree of the bite rod 2 is low, and the purpose of disinfection can be achieved by flushing and disinfection. At the same time, the disinfection time can be reduced to ensure the inspection efficiency. However, for some elderly people, children or patients with poor head balance control ability, it may take a lot of time to position the head before doing CT, which increases the contact time with the bite rod 2 and causes more contamination to the bite rod 2. At this time, the inspection time will be greater than or equal to the preset time parameter, and the immersion disinfection mode will be selected.

[0033] Normally, the time from the beginning to the end of the patient's bite is the total examination time; However, some patients may accumulate saliva in the oral cavity due to a long positioning time, and need to spit it out during the positioning process, or have symptoms such as retching when biting, which may cause the mouth to separate from the bite bar 2. Therefore, step S1 includes: Acquiring bite start information detected by the detector 21; Run the timer to measure time according to the bite information; Acquiring the bite stop information detected by the detector 21; Obtaining the patient's examination information, which at least includes examination completion information and examination in progress information; Pause the timer based on the check in progress message and the bite stopped message; Read the inspection time parameter on the timer according to the bite stop information and the inspection end information; Among them, when the above-mentioned emergency occurs, in order to avoid errors in determining the examination time, the patient's examination information can be retrieved when the patient is separated from the bite bar 2. When the examination information is the examination end information, it means that the patient's examination is over. At this time, the timing can be stopped and the examination time can be read; When the detection information is that the examination is in progress, it means that the patient has encountered the above-mentioned emergency during the occlusion or CT process. At this time, the timing needs to be paused. When the patient has dealt with the emergency, the timing will be started again and the cumulative timing will be performed to avoid the patient's unexpected situation, which will cause the timer to restart and reduce the examination time.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
