Description

Technical Field

[0001] The present application relates to the technical field of automated molecular diagnostic instruments, and more specifically, to a waste treatment system applied to an automated molecular diagnostic instrument. Background Art

[0002] During the use of an automated molecular diagnostic instrument, the used cartridge needs to be treated as medical waste. Currently, the cartridge is generally arranged in a channel, and a waste chute is arranged below one end of the channel. When the cartridge needs to be discarded, a cartridge pusher is used to push the cartridge forward along the channel until the cartridge breaks away from the support of the channel. After the cartridge breaks away from the channel, it slides down the waste chute into the waste recycling bin below.

[0003] Adopting this solution, the size of the entire channel is relatively large, resulting in a relatively large design size of the instrument. At the same time, when the cartridge slides down, it needs to pass through the waste chute, and the cartridge is very likely to get stuck at this place and cannot fall normally, causing the cartridge to be blocked here and unable to enter the recycling bin, increasing the risk of system failure.

[0004] In summary, how to reduce the size of the instrument and at the same time reduce the risk of failure is an urgent problem to be solved by those skilled in the art at present. Summary of the Invention

[0005] In view of this, the purpose of the present application is to provide a waste treatment system applied to an automated molecular diagnostic instrument, which controls the dropping of the discarded cartridge through two openable and closable support arms. At the same time, after the cartridge drops, it does not need to slide along the waste chute, but directly drops downward into the recycling bin, reducing the size of the channel and avoiding the cartridge blocking the waste chute.

[0006] In order to achieve the above purpose, the present application provides the following technical solutions:

[0007] A waste treatment system applied to an automated molecular diagnostic instrument includes an opening and closing control mechanism and two support arms; there is a channel for accommodating the cartridge between the two support arms; the opening and closing control mechanism is connected to the support arms and controls the opening and closing of the two support arms to adjust the distance between the two support arms.

[0008] Optionally, the opening and closing control mechanism includes a separating device and an elastic reset device. The separating device is connected to the support arms and controls the two support arms to open, and the elastic reset device is simultaneously connected to the two support arms and controls the two support arms to close.

[0009] Optionally, the separating device includes a connecting frame, a separating motor and a cam. A connecting frame is fixed to the top of each support arm. The driving shaft of the separating motor is connected to the cam, and the contour of the cam fits with the connecting frame.

[0010] Optionally, it further includes a fault prompt device and a fault sensor for detecting whether the cartridge has fallen off the support arm. When the two support arms are opened and the fault sensor detects that the cartridge has not fallen, the fault prompt device gives a fault prompt.

[0011] Optionally, it further includes a recycling bin for collecting the cartridge that has fallen between the two support arms, and the recycling bin is arranged below the two support arms.

[0012] Optionally, it further includes a liquid suction needle assembly and a liquid suction driving part. The liquid suction needle assembly includes a fixing part, a liquid suction needle, a sleeve and an elastic part. The fixing part is provided with a sliding hole; the sleeve is sleeved and fixed on the outer periphery of the liquid suction needle, the sleeve is arranged in the sliding hole, the sleeve is provided with a sleeve step surface, and the elastic part is connected to the sleeve and controls the sleeve step surface to be close to the upper surface of the fixing part; the liquid suction driving part is connected to the fixing part and controls the lifting of the fixing part.

[0013] Optionally, the liquid suction needle assembly further includes a compression spring screw, the elastic part is a spring, the spring is sleeved on the outer periphery of the compression spring screw, and the upper end and the lower end of the spring are respectively in contact with the head of the compression spring screw and the upper surface of the fixing part.

[0014] Optionally, it further includes an anti-collision sensor arranged on the fixing part. When the liquid suction needle is lifted relative to the fixing part to a preset height, the liquid suction driving part controls the fixing part to stop descending.

[0015] Optionally, the side wall of the support arm facing the channel is provided with a support surface for supporting the cartridge.

[0016] Optionally, it further includes a conveying device for pushing the cartridge to move in the channel. The conveying device includes a conveying driving part, a front push rod for fitting the front end face of the cartridge, and a rear push rod for fitting the rear end face of the cartridge. The front push rod and the rear push rod are both fixedly connected to a push rod bracket, and the conveying driving part is connected to the push rod bracket and drives the push rod bracket to move; when the conveying driving part receives a reset instruction, the conveying driving part controls the push rod bracket to move forward to a preset initial position.

[0017] Through the above solution, the beneficial effects of the waste treatment system applied to the automated molecular diagnostic instrument provided by this application are as follows:

[0018] The waste treatment system provided by this application includes an opening and closing control mechanism and two support arms; there is a channel between the two support arms. During use, the two support arms are controlled by the opening and closing control mechanism to close, and the cartridge is placed in the channel and fixed by the side walls of the channel. When it is necessary to process the waste cartridge, the two support arms are controlled by the opening and closing control mechanism to open, so that the cartridge disengages from the support arms and directly drops downward for collection.

[0019] Since the cartridge does not need to be entirely pushed out of the channel before collection, but the two support arms can be directly opened to make the cartridge drop, the overall size of the channel is shortened, making the structure of the waste treatment system simpler and more compact; at the same time, with the direct dropping method, the cartridge does not need to pass through the waste chute in the prior art, and it can also avoid being stuck when sliding down the waste chute, reducing the risk of blockage.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] Please refer to Figure 1 and Figure 2 , the waste treatment system applied to an automated molecular diagnostic instrument provided by the present application includes: a waste device 1, a fault sensor 2, a recycling bin 3, a pumping mechanism 4, and a conveying device 5.

[0031] Please refer to Figure 3 , the waste device 1 includes a support arm 12 and an opening and closing control mechanism 11.

[0032] There are two support arms 12, which are distributed oppositely, and there is a channel 121 for accommodating the cartridge 6 between them. The two support arms 12 cooperate to fix the cartridge 6. There are various ways to fix the cartridge 6 by the support arms 12.

[0033] For example, in one embodiment, the support arm 12 is provided with a support surface 122 on the side wall facing the channel 121. Specifically, the top of the cartridge 6 generally has a downward plane. Place the top of the cartridge 6 in the channel 121 so that the support surface 122 fits the plane of the cartridge 6, and the cartridge 6 can be supported and fixed.

[0034] For another example, in another embodiment, according to the specifications of the cartridge 6, the distance and clamping force between the two support arms 12 can be designed. When the cartridge 6 is in the channel 121, the cartridge 6 is clamped and fixed by the two support arms 12. At this time, the support surface 122 can be cancelled.

[0035] The opening and closing control mechanism 11 is connected to the support arms 12 and controls the opening and closing of the two support arms 12 to adjust the distance between the two support arms 12. During actual control, it can be to control the two support arms 12 to move simultaneously, making them approach or move away from each other to adjust the distance between the two support arms 12. It can also be that one support arm 12 remains stationary, and the opening and closing control mechanism 11 only controls the movement of the other support arm 12 to achieve the adjustment of the distance between the two support arms 12. There are various options for the opening and closing control mechanism 11 to control the movement of the support arms 12.

[0036] For example, in one embodiment, the opening and closing control mechanism 11 controls the two support arms 12 to open in a telescopic manner. The opening and closing control mechanism 11 can specifically be a telescopic element such as a cylinder, a hydraulic cylinder, a lead screw, etc., with its two ends respectively connected to the two support arms 12.

[0037] For another example, in another embodiment, the opening and closing control mechanism 11 uses the same motor to drive two racks to move in opposite directions, and the two racks are respectively fixedly connected to the two support arms 12. Or a rack is arranged on one support arm 12, and the motor controls the linear movement of the rack.

[0038] For yet another example, in another embodiment, the opening and closing control mechanism 11 includes a separating device 111 and an elastic reset device 112. Among them, the separating device 111 is connected to the support arms 12 and controls the two support arms 12 to open. The elastic reset device 112 is simultaneously connected to the two support arms 12. Specifically, during actual arrangement, the separating device 111 and the elastic reset device 112 can be distributed at both ends of the support arms 12. The separating device 111 pushes the two support arms 12 to open, and after the separating device 111 retracts, the elastic reset device 112 automatically drives the two support arms 12 to approach each other through the elastic restoring force.

[0039] Optionally, in one embodiment, the separating device 111 includes a connecting frame 1111, a separating motor 1112, and a cam 1113. A connecting frame 1111 is fixed to the top of each support arm 12. The drive shaft of the separating motor 1112 is connected to the cam 1113, and the contour of the cam 1113 fits with the connecting frame 1111. During the working process, the separating motor 1112 rotates to drive the cam 1113 to rotate, and the eccentric contour of the cam 1113 pushes the connecting frame 1111 to move linearly, thereby controlling the movement of the support arm 12. During actual arrangement, the connecting frame 1111, the separating motor 1112, and the separating cam 1113 can all be arranged on the top of the support arm 12. The waste disposal device 1 adopting the cam 1113, the separating device 111, and the elastic reset device 112 can reduce the overall size of the channel 121 and make the structure of the waste disposal system more compact.

[0040] The failure sensor 2 works in cooperation with the failure prompt device. The failure sensor 2 is used to detect whether the cartridge 6 has fallen off the support arm 12. The failure sensor 2 is arranged at the bottom of the support arm 12 and is opposite to the cartridge 6. According to whether the failure sensor 2 is blocked by the cartridge 6, it can be determined whether the cartridge 6 has fallen off the support arm 12. If the support arm 12 has been opened in place and the failure sensor 2 still detects the cartridge 6, through logical control, the failure prompt device reports a failure to prompt the user to perform corresponding maintenance and reduce the risk of the system.

[0041] The recycling bin 3 is used to collect the cartridges 6 that fall from the support arm. The recycling bin 3 is arranged directly below the two support arms 12. The cartridges 6 that fall from the channel 121 can directly fall into the interior of the recycling bin 3, avoiding blocking the waste chute. In practical applications, the recycling bin 3 can be disposable, or an ultraviolet light source can be added to the recycling bin 3 for disinfection, or a disposable liner can be set in the recycling bin 3 to achieve the reuse of the recycling bin 3.

[0042] Optionally, in one embodiment, a detection sensor can be arranged in the recycling bin 3 to detect the height of the cartridges 6 stacked in the recycling bin 3, or to detect the total weight of the recycling bin 3 and the waste cartridges 6 inside. When the recycling bin 3 is full and needs to be emptied, the user is notified through the prompt device to empty the recycling bin 3.

[0043] Please refer to Figure 6 , the pumping mechanism 4 includes a liquid suction needle assembly 41, a liquid suction driving part 42, and an anti-collision sensor 43.

[0044] The liquid suction driving part 42 is connected to the liquid suction needle assembly 41 and controls the liquid suction needle assembly 41 to move. The liquid suction driving part 42 can control the vertical movement of the liquid suction needle assembly 41. If necessary, it can also control the horizontal movement of the liquid suction needle assembly 41, and it is only necessary to control the liquid suction needle assembly 41 to move in place according to the preset path.

[0045] Optionally, in one embodiment, the liquid suction driving part 42 includes a lifting motor 421, a synchronous pulley, a synchronous belt 422, a slide rail 423, and a synchronous belt tensioning mechanism. The lifting motor 421 can be a stepper motor. During operation, the lifting motor 421 rotates, and drives the liquid suction needle assembly 41 to move up and down along the provided slide rail 423 through the synchronous belt 422. It can cooperate with the conveying device 5 to move the cartridge 6 in the channel 121. When the reagent hole of the cartridge 6 containing waste liquid is directly below the liquid suction needle 412, the lifting motor 421 controls the liquid suction needle assembly 41 to move downward to the bottom of the reagent hole of the cartridge 6 for liquid pumping. When the waste liquid in the reagent hole of the cartridge 6 is completely pumped out by the liquid suction needle 412, the lifting motor 421 rotates in reverse, and drives the liquid suction needle 412 to lift through the transmission of the synchronous belt 422. Then, the conveying device 5 pushes the cartridge 6 forward to align the liquid suction needle 412 with the next reagent hole on the cartridge 6. The limit positions of the lifting of the liquid suction needle assembly 41 can be controlled by the origin sensor and the limit device.

[0046] The liquid suction needle assembly 41 is used to pump out the waste liquid in the cartridge 6 after the sample processing is completed, separate the liquid waste from the solid waste, and realize the separate disposal of solid and liquid wastes.

[0047] Optionally, in one embodiment, please refer to Figure 7 , the liquid suction needle assembly 41 includes a fixing member 411, a liquid suction needle 412, a sleeve 413, and an elastic member 414. The fixing member 411 is provided with a sliding hole; the sleeve 413 is sleeved and fixed on the outer periphery of the liquid suction needle 412. The sleeve 413 is arranged in the sliding hole and can move up and down along the sliding hole. The sleeve 413 is provided with a sleeve step surface. The elastic member 414 is connected to the sleeve 413 and controls the sleeve step surface to move downward close to the upper surface of the fixing member 411; the liquid suction driving part 42 is connected to the fixing member 411 and controls the lifting of the fixing member 411.

[0048] Specifically, the liquid suction needle 412 is used to complete the pumping of the waste liquid in the hole of the cartridge 6. The liquid suction needle 412 needs to be connected to the waste liquid pumping pump through a hose. The waste liquid pumping pump is connected to the waste liquid bucket through a hose. When the liquid suction needle 412 moves to the bottom of the corresponding hole of the cartridge 6, the waste liquid pumping pump operates to pump the waste liquid in the hole of the cartridge 6 into the waste liquid bucket.

[0049] Optionally, the waste liquid bucket can be provided with a liquid level sensor for detecting the liquid level in the waste liquid bucket. When the waste liquid bucket is full, it can prompt the customer or the system to actively discharge the waste liquid in the waste liquid bucket to the outside.

[0050] The elastic member 414 applies a downward force to the sleeve 413 by virtue of its own elasticity, causing the sleeve 413 to abut against the upper surface of the fixing member 411. There are various arrangement forms for the elastic member 414. For example, the elastic member 414 can be a spring. Correspondingly, the liquid suction needle assembly 41 further includes a compression spring screw 415. The elastic member 414 is sleeved on the outer periphery of the compression spring screw 415, and the upper end and the lower end of the elastic member 414 are respectively in contact with the head of the compression spring screw 415 and the upper surface of the fixing member 411. For another example, the upper end and the lower end of the elastic member 414 are respectively connected to the lower surface of the sleeve 413 and the upper surface of the fixing member 411. When the sleeve 413 moves upward relative to the fixing member 411, the elastic member 414 directly pulls the sleeve 413 downward.

[0051] During the working process, the liquid suction needle assembly 41 descends integrally under the drive of the liquid suction drive part 42, and the liquid suction needle 412 enters the reagent hole of the cartridge 6. The elastic member 414 provides a margin of movement for the liquid suction needle 412, enabling the liquid suction needle 412 to move up and down relative to the fixing member 411, so that the bottom of the liquid suction needle 412 is in full contact with the bottom of the reagent hole of the cartridge 6, ensuring that the waste liquid in the cartridge 6 can be pumped out completely.

[0052] The anti-collision sensor 43 is arranged on the fixing member 411. Both the anti-collision sensor 43 and the liquid suction drive part 42 are electrically connected to the electric control system. When the liquid suction needle 412 is lifted relative to the fixing member 411 to a preset height, the anti-collision sensor 43 sends a in-place command to the electric control system, and the electric control system controls the operation of the liquid suction drive part 42 according to the in-place command to stop the fixing member 411 from descending. Specifically, when the liquid suction needle 412 collides excessively with the bottom of the reagent hole of the cartridge 6, the lifting height of the liquid suction needle 412 relative to the fixing member 411 exceeds the limit value. At this time, the liquid suction needle 412 can trigger the anti-collision sensor 43, and the system stops running to prevent the liquid suction needle 412 from being damaged.

[0053] It can be understood that an encoder can also be provided on the lifting motor 421 of the liquid suction drive part 42 to control the moving stroke of the liquid suction needle assembly 41 in combination with the encoder. At this time, the anti-collision sensor 43 can be cancelled.

[0054] Please refer to Figure 4 and Figure 5 , the conveying device 5 is used to push the cartridge 6 to move in the channel 121, so that the cartridge 6 moves to different operating stations. There are various choices for the structure of the conveying device 5.

[0055] Optionally, in one embodiment, the conveying device 5 includes a conveying drive part 51, a front push rod 52, a rear push rod 53 and a push rod bracket 54. The conveying drive part 51 is connected to the push rod bracket 54 and drives the push rod bracket 54 to move back and forth.

[0056] Specifically, the transfer driving unit 51 may specifically include a stepper motor, a synchronous pulley, a synchronous belt, a slide rail, and a synchronous belt tensioning device. The limit positions of the movement of the push rod bracket 54 can be controlled by an origin sensor and a limit device. During operation, the stepper motor rotates, drives the push rod bracket 54 to move through the synchronous belt, and the push rod bracket 54 pushes the cartridge 6 to move in the channel 121 so that each reagent hole of the cartridge 6 can be moved to a position below the liquid suction needle 412.

[0057] Both the front push rod 52 and the rear push rod 53 are fixedly connected to the push rod bracket 54. The front push rod 52 is used to fit the front end face of the cartridge 6, and the rear push rod 53 is used to fit the rear end face of the cartridge 6. In the prior art, during the process of separating liquid waste from the cartridge 6, if an abnormal shutdown occurs, after restarting, since the electronic control system cannot recognize the correct position of the current cartridge 6, it is impossible to control the cartridge 6 to continue operating. In the solution of this embodiment, after an abnormal shutdown, the electronic control system can automatically generate an error signal and then send a reset instruction to the transfer driving unit 51. When the transfer driving unit 51 receives the reset instruction from the electronic control system, the transfer driving unit 51 controls the push rod bracket 54 to move forward to a preset initial position, and the rear push rod 53 pushes the cartridge 6 out of the channel 121, and then the operation of separating liquid waste from the cartridge 6 is carried out again, ensuring that the cartridge 6 that is not discarded and not subjected to solid-liquid separation in the channel 121 can be subjected to solid-liquid separation again after the equipment has an abnormal shutdown, reducing secondary pollution.

[0058] It should be noted that in practical applications, it is preferable to arrange the transfer device 5 of the above structure in cooperation with the support surface 122. At this time, the two support arms 12 remain in their original positions without opening, and the transfer device 5 can also push the cartridge 6 to move in the channel 121, which is more convenient to operate. Of course, for the solution of clamping and fixing the cartridge 6 by the two support arms 12, a transfer device 5 can also be arranged. Correspondingly, at this time, the structure of the push rod bracket 54 can be designed so that the push rod bracket 54 can support the cartridge 6. If an abnormal shutdown occurs, the two support arms 12 need to be opened a certain distance first, and then the transfer device 5 is used to push the cartridge 6 out of the channel 121.

[0059] It should be noted that the pumping mechanism 4 is used to separate the waste liquid from the cartridge 6, collect the liquid waste and solid waste separately, and achieve solid-liquid separation; if solid-liquid separation is not required, the pumping mechanism 4 can be omitted. The fault sensor 2 is used to improve the safety of the system, and the fault sensor 2 and the fault prompt device can be omitted. The transfer device 5 is used to control the movement of the cartridge 6 along the channel 121, and the cartridge 6 can also reach each operation station by other means.

[0060] In practical applications, it is preferred that the waste treatment system is provided with a waste disposal device 1, a recycling bin 3, a conveying device 5, and a pumping mechanism 4 at the same time. Its working process is as follows: After the pumping mechanism 4 pumps out the waste liquid in each reagent hole of the cartridge 6, the conveying device 5 will push the cartridge 6 to continue moving in the channel 121 until the cartridge 6 moves to the waste position. Then, the opening and closing control mechanism 11 in the waste disposal device 1 acts to control the two support arms 12 to open, so that the cartridge 6 drops downward into the recycling bin 3; when the cartridge 6 drops, the opening and closing control mechanism 11 acts to control the support arms 12 to reset.

[0061] The waste treatment system cooperates with the conveying device 5, the pumping mechanism 4, the waste disposal device 1, the recycling bin 3, etc. After sample processing, it can safely and effectively process the used cartridge 6 and the waste liquid in the cartridge 6. The waste treatment system drives the cartridge 6 to move through the conveying device 5, cooperates with the pumping mechanism 4 to separate the liquid waste from the solid waste, and then puts the cartridge 6 into the recycling bin 3 through the waste disposal mechanism, realizing the function of discarding the used cartridge 6 and the waste liquid in the cartridge 6 after sample processing. The system is safe and reliable, has a small risk of system pollution, and at the same time has a simple structure and is easy to maintain.

[0062] As can be seen from the above embodiments, the beneficial effects of the waste treatment system provided by the present application are as follows:

[0063] When applying the waste treatment system provided by the present application, the two support arms 12 can be directly opened to make the cartridge 6 drop. The cartridge 6 does not need to be integrally pushed out of the channel 121 and then recycled. Therefore, the overall size of the channel 121 is shortened, and the structure of the waste treatment system is more simple and compact. At the same time, by adopting the direct dropping method, the cartridge 6 does not need to pass through the waste chute in the prior art, and it can also avoid being stuck when the cartridge 6 slides down along the waste chute, reducing the risk of blockage.

[0064] In this specification, each embodiment is described in a progressive manner. The key points of each embodiment are the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other.

[0065] The above has introduced in detail the waste treatment system applied to an automated molecular diagnostic instrument provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
