That is, this medical equipment can disinfect to the scanning chamber through the sterilizer of installation on the scanning intracavity inner wall, and when the scanning bed was located the scanning intracavity, the sterilizer can also disinfect to the scanning bed. Therefore, the sterilizer arranged on the inner wall of the scanning cavity can realize self-disinfection of the medical equipment without accessing other disinfection equipment.

Based on the above embodiments, the structure and arrangement of the sterilizer in the present application will be explained with reference to fig. 3 to 5.

In one embodiment, as shown in fig. 3, the sterilizer 130 includes an atomizer 131, a porous structure 132, and an air duct 133. Wherein, the atomizer 131 is used for atomizing the liquid disinfectant to generate aerosol; the porous structure 132 is used as an output port of the aerosol and is arranged in the inner wall of the scanning cavity; a vent conduit 133 connects the nebulizer and porous structure to transport the aerosol formed by the nebulization from the nebulizer to the porous structure.

In one possible implementation mode, the vent pipe is made of a flexible and extensible material and can be extended according to actual requirements; alternatively, the vent tube may be extended by means of a connecting hose to connect the atomiser with the porous structure.

As an example, referring to fig. 4 (a), the atomizer 131 may be disposed at one end of the scanning chamber 110 (fig. 4 (a) exemplifies an end close to an initial placement position of the scanning bed), the porous structure 132 may be disposed at a middle position of a top portion of an inner wall of the scanning chamber 110, and an aerosol generated by atomizing the liquid disinfectant by the atomizer 131 is delivered to the porous structure 132 through the ventilation duct 133, so that the aerosol can enter the scanning chamber 110 through the porous structure 132 to sterilize the scanning chamber 110.

So, aerosol after the atomizing can be through setting up the porous structure at scanning intracavity wall top intermediate position, and the rapid diffusion is to whole scanning chamber to carry out abundant disinfection to the scanning chamber.

As another example, referring to (b) in fig. 4, the atomizer 131 and the porous structure 132 are disposed at the same end of the scanning chamber (fig. 4 (b) exemplifies an end close to the initial placement position of the scanning bed), and the atomizer 131 atomizes the liquid sterilizing fluid to generate aerosol. A vent conduit 133 (not shown in fig. 4 (b)) connected to the nebulizer 131 and the porous structure 132 delivers the aerosol to the porous structure 132 so that the aerosol can enter the scanning chamber 110 through the porous structure 132, disinfecting the scanning chamber 110.

So, the aerosol after the atomizing can be through setting up the porous structure in scanning intracavity wall one end, spreads to whole scanning chamber to disinfect to the scanning chamber.

Optionally, a vortex fan is arranged in the ventilation pipeline; the vortex fan is used for changing the circulation state of the aerosol in the ventilation pipeline.

Specifically, the aerosol is pushed toward the porous structure by the wind pressure generated by the vortex fan to accelerate the flow rate of the aerosol in the ventilation duct.

The number of the vortex fans arranged in the ventilation pipeline can be one or more, and the embodiment does not limit the number.

Optionally, sterilizer 130 may further include a tank for storing a liquid sterilizing fluid. Specifically, the atomizer can set up the liquid outlet at the liquid reserve tank to carry out atomization process to the liquid antiseptic solution that flows out.

Further, if the liquid reserve tank sets up in different positions with the atomizer, also can be connected liquid reserve tank and liquid outlet and atomizer through the pipe to carry the liquid antiseptic solution in with the liquid reserve tank to atomizer department through the pipe.

In this embodiment, the atomizer in the sterilizer may atomize the liquid sterilizing fluid to generate an aerosol, which flows through the vent conduit to the porous structure. Further, the aerosol diffuses through the porous structure into the scanning chamber to disinfect the scanning chamber.

In another embodiment, the sterilizer 130 provided herein may be embodied as an ultraviolet lamp, and at least one end of the ultraviolet lamp is fixedly connected to the inner wall of the scanning chamber.

Referring to fig. 5 (a), when the length of the uv lamp tube is less than the preset length threshold, a plurality of uv lamps may be provided, and one end of each uv lamp is fixedly installed on the top of the inner wall of the scanning chamber, so as to sterilize the scanning chamber 110 by the uv rays emitted from the uv lamps.

In the present application, the number of the ultraviolet lamps is not limited, and fig. 5 (a) is only an example in which four ultraviolet lamps are vertically installed.

The length threshold may be set according to size information of the scanning cavity and scanning requirements of the medical apparatus, for example, 10cm, 20cm, and the like.

Referring to fig. 5 (b), when the length of the ultraviolet lamp tube is greater than the preset length threshold, both ends of the ultraviolet lamp tube may be fixedly installed on the top of the inner wall of the scanning chamber to sterilize the scanning chamber 110 by the ultraviolet rays emitted from the ultraviolet lamp tube.

The number of the ultraviolet lamps installed along the central axis direction of the top of the scanning chamber may be one or more, and fig. 5 (b) is only one example.

As an example, the fixed end of the ultraviolet lamp tube and the inner wall of the scanning chamber can be fixed by a nut to ensure the stability of the ultraviolet lamp tube after being fixed.

In addition, the ultraviolet lamp tube can be arranged at other positions of the inner wall of the scanning cavity, the ultraviolet rays emitted by the ultraviolet lamp tube only need to be guaranteed to effectively disinfect the scanning cavity, and no disinfection blind area exists.

In this embodiment, the ultraviolet lamp tube disposed on the inner wall of the scanning chamber can effectively sterilize the inside of the scanning chamber, and the sterilization is low in cost and easy to implement.

Based on above-mentioned embodiment, the sterilizer not only can be at scanning intracavity wall fixed mounting, also can install in a flexible way to make the sterilizer can be at scanning intracavity reciprocating motion, fully disinfect the scanning chamber, reduce the disinfection blind area.

Based on this concept, in one embodiment, as shown in FIG. 6, a second slide rail 150 is disposed on an inner wall of the scanning chamber 110 of the medical apparatus 100. The sterilizer 130 is disposed on the second slide rail 150 and is moved relative to the scan chamber by the second slide rail 150.

Wherein, the second slide rail can set up the optional position at scanning intracavity wall, as long as guarantee that the sterilizer on the second slide rail can disinfect to whole scanning intracavity portion.

In a possible implementation manner, the second slide rail is arranged on a central axis of the top of the inner wall of the scanning cavity.

In another possible implementation manner, the second slide rail may also be disposed in the inner wall of the scanning chamber at a predetermined distance from the central axis of the top portion. For example, as shown in fig. 6, the second slide rail is disposed at a position a or B of the inner wall of the scanning chamber parallel to the scanning bed.

In addition, the number of the disinfectors can be one or more, and the embodiment does not limit the number.

As an example, when the number of the sterilizers is plural and the second slide rail is one, the plural sterilizers may be collectively installed at the same end of the second slide rail, and the plural sterilizers move along the second slide rail to sterilize the inside of the scanning chamber.

As another example, when the number of the sterilizers is plural and the number of the second slide rails is plural, at least one sterilizer is disposed on each of the second slide rails, and the plural sterilizers move along the corresponding second slide rails to sterilize the inside of the scanning chamber. Compared with a second slide rail, the second slide rail is adopted to simultaneously drive a plurality of disinfectors to disinfect the scanning cavity, so that the disinfection efficiency can be improved.

In this embodiment, adopt second slide rail installation sterilizer to drive the sterilizer through the second slide rail and remove, disinfect the scanning intracavity portion comprehensively, can reduce the disinfection blind area.

In one embodiment, in the medical apparatus, the number of the sterilizers is multiple, and the multiple sterilizers are arranged on the inner wall of the scanning chamber according to a preset arrangement rule.

The preset arrangement rule can be a linear arrangement or a curve arrangement, and in the preset arrangement rule, the disinfectors can be installed at equal intervals or at any intervals, and the embodiment does not limit the installation.

In one possible implementation, a plurality of sterilizers are installed on a central axis at the top of the inner wall of the scanning chamber; and/or a plurality of sterilizers are installed at symmetrical positions (such as a position A and a position B in FIG. 6) of the inner walls of the left and right sides of the scanning chamber.

In this embodiment, a plurality of sterilizers are installed on the inner wall of the scanning chamber, and compared with a mode of installing one sterilizer by using a second slide rail, the capital cost for installing the second slide rail is saved. Moreover, the disinfectors can comprehensively disinfect the inside of the scanning cavity, so that the disinfection efficiency is improved.

In one embodiment, as shown in fig. 7, the medical apparatus 100 further comprises a carrier detection device 160; a carrier detection device 160 is provided in the scanning bed 120 for detecting the presence of a carrier on the scanning bed 120.

The carrier can be a human body or other organisms, and in practical application, the carrier needs to lie on a scanning bed so as to convey the carrier into a scanning cavity through the scanning bed for scanning and imaging.

In one possible implementation, the carrier detection device 160 includes at least one of a visual sensor, a pressure sensor, and a laser sensor.

Further, in order to ensure the carrier detection accuracy, when the carrier detection device is arranged, it is required to ensure that the range of the carrier detection device capable of sensing the scanning bed is as large as possible.

(1) If the carrier detection device is a vision sensor and/or a laser sensor, the vision sensor and the laser sensor are arranged at different ends or the same end of the scanning bed.

If the carrier detection means comprises a visual sensor, the visual sensor may be arranged at either end of the scanning bed to determine whether a carrier is present in the scanning bed by acquiring a visual identification.

As one example, the visual sensor may be an RGB camera, an RGBD camera, a binocular camera, or the like.

If the carrier detection means comprises a laser sensor, the laser sensor may be arranged at either end of the scanning bed to detect the presence of a carrier in the scanning bed by emitting a laser signal.

As one example, the laser sensor may be a laser radar, a millimeter wave radar, or the like.

Because the vision sensor and the laser sensor both have own perception ranges, the carriers outside the perception ranges can not be effectively detected. Based on this, the carrier detection device can include vision sensor and laser sensor simultaneously to compensate the limitation of single sensor, thus whether exist the carrier in the scanning bed and carry out effective detection.

If the carrier detection device comprises a vision sensor and a laser sensor, the vision sensor and the laser sensor can be arranged at the same end of the scanning bed, or at different ends of the scanning bed.

(2) If the carrier detection device is a pressure sensor, the pressure sensor is arranged at a preset position in the scanning bed.

The preset position can be any region on the scanning bed. For example, as shown in fig. 7, the preset position may be a central position of the scanning bed.

That is, the pressure sensor is disposed at the center of the scanning bed, and the pressure change of the scanning bed is detected to indirectly determine whether the carrier exists in the scanning bed.

It should be noted that the pressure sensor may be disposed in the bed body of the scanning bed, or may be disposed at the bottom of the scanning bed like the first slide rail, which is not limited in this embodiment.

It should be understood that when the interior of the scanning chamber and the scanning bed are disinfected by the disinfector, no other organisms should exist in the placing space of the medical equipment, so that the disinfection process is prevented from causing harm to other organisms or not completely disinfecting. Based on this, can detect whether to have the carrier in the scanning bed through carrier detection device, if exist then stop the disinfection, if do not exist then disinfect scanning intracavity portion and scanning bed according to the disinfection order of predetermineeing.

In the embodiment, the carrier detection device is added in the scanning bed of the medical equipment, so that whether a carrier exists on the scanning bed can be effectively detected, and the disinfection operation is interrupted in time.

In summary of the above embodiments, the working principle of the medical apparatus is as follows: judging whether the medical equipment meets a preset disinfection condition or not; under the condition that the medical equipment meets the disinfection condition, the disinfector disinfects the inside of the scanning cavity and the scanning bed moved to the inside of the scanning cavity in sequence.

Wherein the sterilization conditions include: the scanning bed is in an initial placement position outside the scanning chamber, no carrier is present on the scanning bed, and the medical device has not been scanned in sequence after a previous bed sterilization.

The process of judging whether the medical equipment meets the disinfection condition is as follows: firstly, judging whether the scanning bed is located at an initial placement position outside the scanning cavity, and if the scanning bed is located at the initial placement position outside the scanning cavity, detecting whether a carrier exists on the scanning bed through a carrier detection device; if the scanning bed does not have a carrier, judging whether the medical equipment after the last scanning bed disinfection scans the sequence or not, if so, determining that the medical equipment meets the preset disinfection condition, and starting a disinfection flow so as to disinfect the scanning cavity and the scanning bed in sequence through a disinfector arranged on the inner wall of the scanning cavity.

Further, when disinfecting medical equipment, the disinfector arranged on the inner wall of the scanning cavity is opened to disinfect the inside of the scanning cavity, and in the disinfection process of the scanning cavity, whether a disinfection interruption event exists or not is detected. If the disinfection interruption event exists, stopping the disinfection process, and finishing the disinfection; and if the disinfection interruption event does not exist, waiting for the disinfection of the scanning cavity to be finished. And after the scanning chamber is disinfected, the scanning bed is moved to the inside of the scanning chamber so as to disinfect the scanning bed.

Similarly, when the scanning bed in the scanning cavity is disinfected by the disinfector arranged on the inner wall of the scanning cavity, whether a disinfection interruption event exists is detected. If the disinfection interruption event exists, stopping the disinfection process, and finishing the disinfection; and if the disinfection interruption event does not exist, waiting for the end of the disinfection of the scanning bed. After the scanning bed is disinfected, the disinfector is closed, the scanning bed is moved to a preset initial placing position outside the scanning cavity, and the disinfection operation is finished.

In a possible implementation manner, the disinfection time of the scanning cavity and the scanning bed can be preset, after the disinfector is started, the disinfection time is calculated, and if no disinfection interruption event exists in the disinfection process, the disinfection of the scanning cavity/the scanning bed is considered to be finished after the preset disinfection time is reached.

As one example, the above-described sterilization interrupt events include, but are not limited to, the following:

(1) Non-sterile procedure triggered movement of the scanning bed.

Specifically, if the carrier detection device detects that the carrier exists on the scanning bed, the non-disinfection process is considered to cause the movement of the patient bed.

As an example, if the carrier detection device is a pressure sensor, when the bed pressure value of the scanning bed detected by the pressure sensor is greater than a preset threshold, the carrier is considered to be present on the scanning bed. And in the case of a carrier on the scanning bed, the scanning bed cannot be sterilized. Therefore, in the disinfection process, if the scanning bed moves towards the inside of the scanning cavity along the first slide rail due to the fact that the carrier exists on the scanning bed, the scanning bed triggered by the non-disinfection process is determined to move.

(2) The scanning room in which the medical equipment is located is not in a closed state.

In a possible implementation manner, whether the scanning room is in a closed state or not can be determined by acquiring video images through monitoring equipment in the scanning room and judging whether a door of the scanning room is opened or not in the disinfection process.

Wherein, when the scanning room is not in the confined state, probably the staff gets into the scanning room, then stops disinfecting medical equipment, avoids gaseous other organisms in to the scanning room of disinfecting to cause the injury.

(3) Whether the scanned object information registration exists in the scanning imaging system is detected.

If the medical equipment is available, the characteristic may be that a doctor needs to use the medical equipment to scan the scanned object, fills in relevant information of the scanned object, and sets scanning parameters, in this case, the disinfection of the medical equipment is stopped, so as to ensure that the doctor can preferentially use the medical equipment to examine the scanned object, and then the disinfection is performed after the scanning is finished.

(4) It is detected whether a positioning laser light in the medical device is turned on.

If the laser positioning lamp is turned on, the characterization may be that a doctor needs to scan the scanning object, in which case the disinfection of the medical equipment is stopped, and the disinfection is performed after the scanning is finished.

It will be appreciated that during the sterilization process, when any sterilization interruption event is detected, it is necessary to immediately stop sterilization, waiting until it is again determined that the medical device meets the preset sterilization conditions.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
