Description

Technical Field

[0001] The present invention relates to a waste collection device for collecting and processing waste materials generated during medical procedures. Background Art

[0002] During the implementation of specific surgical procedures, wastes of various types such as liquids, semi-solids, and solids will inevitably be generated, specifically including body fluids such as blood, and perfusion solutions introduced into the surgical site during the surgical procedure. In addition, solid and semi-solid wastes generated during the surgical procedure include tissue fragments and small pieces of surgical materials that may remain in the body part. Ideally, once the waste is generated, it will be collected so that it neither soils nor contaminates the surgical site, nor becomes a biological hazard in the operating room or other locations where the surgical procedure is performed.

[0003] In the prior art, there are various waste collection and processing systems available for medical staff to collect the waste generated during the surgical procedure during or after the surgery. Its principle is mainly to generate a suction force through a vacuum source to suck the waste generated at the surgical site into a specific collection container. That is, after the system is started, the suction force generated by the vacuum source reaches the surgical site, and thus the waste is sucked and flows into a specific collection container through the pipeline in contact with the surgical site. In the medical waste collection and processing system, the waste materials are collected in a waste collection container connected to the vacuum source. One solution in the prior art is to use a large-capacity waste collection container to suck and store the waste. The larger the capacity of the container, the lower the accuracy of its scale, which is not conducive to accurately calculating the volume of the waste. At the same time, usually during the medical procedure, medical staff need to glance at the waste collection container to estimate the amount of waste to be extracted subsequently, so as to control the surgery. However, for a container with a large capacity, the intuitiveness of the volume is worse, which is not conducive to estimation. But when directly using a container with a small volume, although it is easy to intuitively estimate, the container will be filled up more quickly, which will cause the interruption of the surgical procedure to empty the waste collection container, and the interruption of the surgical procedure will bring a lot of inconvenience and risks to the treatment. At the same time, whether it is a large container or a small container, there is another disadvantage that it is impossible to select different volumes according to the type of surgery to perform.

[0004] To solve this technical problem, a waste collection container with two chambers of different volumes is proposed. The intuitive estimation and accurate measurement are achieved through the chamber with a small volume, and the storage of a large amount of waste is achieved through the chamber with a large volume. However, in this technical solution, since both chambers are connected to the same negative pressure source, during the operation of transferring the waste in the small chamber to the large chamber, due to the same pressure in both chambers, the transfer speed is slow through the self-flow transfer method. However, since many surgeries cannot be delayed, this technical solution will have a very adverse impact when performing certain surgeries; for other surgeries, the progress and smoothness of the surgery will also be greatly affected due to the slow transfer speed, bringing many inconveniences to patients and medical staff.

[0005] Precisely because the speed of transferring waste from the small chamber to the large chamber is slow and the transfer is not thorough, in the prior art, the liquid levels of the waste in the two chambers of the waste collection container can only be measured separately by two different liquid level measuring instruments. Firstly, the high-precision liquid level measuring instrument is expensive. Secondly, additional openings need to be made in the waste collection container, increasing the process cost and also affecting the structure of the waste collection container due to the relatively large volume of the liquid level measuring instrument. Summary of the Invention

The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0053] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] As Figures 1 - 4 shown, Figure 1 and Figure 2 show a waste collection and treatment system 10, which includes a waste collection device 100 and a docking device 200. Figure 1 Fig. shows the waste collection and treatment system 10 when the waste collection device 100 and the docking device 200 are not docked. Figure 2 Fig. shows the waste collection and treatment system 10 when the waste collection device 100 and the docking device 200 are docked. The waste collection device 100 can be connected to an external suction pipeline (not shown in the figure) through a consumable cartridge 300, and the external suction pipeline can be connected to a suction joint (not shown in the figure). The suction joint can be a separate joint or attached to a surgical device. The suction force at the suction joint transports the waste through the external suction pipeline into the waste collection device 100 for storage. After the docking device 200 is docked with the waste collection device 100, it can empty the waste in the waste collection device 100 through the docking device 200, and at the same time, a cleaning passage for cleaning the waste collection container 109 of the waste collection device 100 can be formed. The discharge circuit control and flushing circuit control of the waste collection and treatment system 10 are known to those skilled in the art and will not be elaborated here.

[0055] The waste collection device 100 is used in the waste collection and treatment system 10 to collect the waste generated during the medical process and to dock with the docking device 200 to discharge the waste. Refer to Figure 1 and Figure 2The waste collection device 100 includes: a portable trolley 108, at least one waste collection container 109 installed on the portable trolley, a mating bracket 110, two collection end connectors 112, 114, and two floating sleeves 111, 113.

[0056] The portable trolley 108 is moved by four first rollers 105 installed thereon. Specifically, the portable trolley 108 further includes a collection end housing 101. A push handle 102 is provided in the middle part of the housing 101, and a collection end display screen 103 is provided on the top of the collection end housing 101. Preferably, the collection end display screen 103 is foldably arranged on the collection end housing 101. The portable trolley 108 is also provided with a support hanging rod 104.

[0057] See Figure 3 , Figure 3 is a schematic diagram of the front internal structure of the waste collection device of the present invention. The waste collection container 109 is installed on the portable trolley 108 and is used to store the waste generated during the medical process. In this embodiment, one waste collection container 109 is provided. The waste collection container 109 has a first cavity 116 and a second cavity 117, where the volume of the first cavity 116 is smaller than the volume of the second cavity 117. The number of waste collection containers can also be two, that is, it is equivalent to separating the first cavity 117 and the second cavity 117 to form two independent waste collection containers. The waste collection container 109 is installed inside the collection end housing 101. Preferably, corresponding observation windows are provided on the collection end housing 101 to observe the waste in the waste collection container 109, such as the liquid level or color. In this embodiment, a first observation window 106 and a second observation window 107 are correspondingly provided to observe the first cavity 116 and the second cavity 117 respectively.

[0058] The mating bracket 110 is installed on the chassis 118 of the portable trolley 108 and is used to mate with the docking device 200. The mating bracket 110 forms a mating space 1100 for accommodating the mating head of the docking device 200.

[0059] Two collection end connectors 112, 114 are attached to the mating bracket 110 and are respectively connected to at least one waste collection container 109. One of the collection end connectors 112 is used to discharge the waste in the waste collection container 109, and the other collection end connector 114 is used to introduce the cleaning liquid for cleaning at least one waste collection container 109. In this embodiment, for the convenience of distinction, the collection end connector 112 for discharging the waste in the waste collection container 109 is called the first collection end connector 112, and the collection end connector 114 for introducing the cleaning liquid for cleaning the waste collection container 109 is called the second collection end connector 114. See Figure 4 ,Figure 4 This is a schematic diagram of the internal structure of the side of the waste collection device of the present invention. As Figure 4 shown, the first collection end joint 112 is connected to the waste collection container 109 through the discharge pipe 122. Specifically, the first collection end joint 112 is connected to the first cavity 116 of the waste collection container 109 through the discharge pipe 122, that is, one end of the discharge pipe 122 is connected to the first collection end joint 112, and the other end is connected to the bottom of the first cavity 116; the second collection end joint 114 is connected to the second cavity 117 of the waste collection container 109 through the cleaning pipe 124, that is, one end of the cleaning pipe 124 is connected to the second collection end joint 114, and the other end is connected to the top of the second cavity 117.

[0060] Two floating sleeves 111, 113 are installed on the mating bracket 110 and sleeved on the two collection end joints 112, 114 correspondingly, for guiding the two docking end joints of the docking device 200 to be correspondingly connected to the two collection end joints 112, 114; the two floating sleeves 111, 113 can move suspended relative to the mating bracket 110 and guide the two docking end joints to engage with the two collection end joints 112, 114. When the docking end joints of the docking device 200 are not connected, the corresponding floating sleeves 111, 113 are in the initial position; during the process of connecting the docking end joints, the floating sleeves 111, 113 can move suspended relative to the mating bracket 110 and guide the two docking end joints to engage with the two collection end joints 112, 114.

[0061] See Figures 1 - 7 In this embodiment, the waste collection device 100 includes:

[0062] A portable trolley 108; a mating bracket 110, the mating bracket 110 is installed on the portable trolley 108 and is used for mating with the docking device 200;

[0063] A waste collection container 109, the waste collection container 109 is installed on the portable trolley 108 and is used for storing the waste generated during the medical process; a first collection end joint 112 and a second collection end joint 114, attached to the mating bracket 110 and connected to the waste collection container 109, for discharging the waste in the waste collection container 109; the second collection end joint 114, attached to the mating bracket 110 and connected to the waste collection container 109, for introducing the cleaning liquid for cleaning the waste collection container 109.

[0064] Among them, the waste collection container 109 includes a first cavity 116 and a second cavity 117; a partition wall 902 is provided between the first cavity 116 and the second cavity 117; the partition wall 902 is further provided with a movable valve 908 that can connect or close the first cavity 116 and the second cavity 117; the first cavity 116 is provided with a fluid delivery hole 912 for conveying waste, a suction hole 911 for pneumatic connection with a vacuum source 150, and a cleaning access hole 913, and the second cavity 117 is provided with a liquid discharge hole 916;

[0065] Among them, the movable valve 908 is arranged in the waste collection container 109 for connecting or isolating the first cavity 116 and the second cavity 117;

[0066] See Figure 12 , the valve controller 801 is connected to the movable valve 908. When it is necessary to transfer the waste in the first cavity 116 to the second cavity 117, the valve controller 801 controls the movable valve 908 to connect the first cavity 116 and the second cavity 117, and in the state where the first cavity 116 and the second cavity 117 are connected, the valve controller 801 controls the movable valve 908 to perform an evacuation action. When the transfer of the waste in the first cavity 116 is completed, the valve controller 801 controls the movable valve 908 to isolate the first cavity 116 and the second cavity 117;

[0067] A liquid level measuring instrument 923 is arranged in the first cavity 116 for measuring the liquid level of the waste in the first cavity 116; a liquid level processing module 802 is used for, after the movable valve 908 is opened, calculating the liquid level of the waste discharged into the second cavity 117 according to the liquid level of the waste in the first cavity 116 obtained by the liquid level measuring instrument 923. In this embodiment, the valve controller 801 and the liquid level processing module 802 can be integrated under the collection end display 103.

[0068] See Figure 13, the liquid level processing module 802 specifically includes: a first recording unit 803, a second recording unit 804, and an arithmetic unit 805, where the arithmetic unit 805 is respectively connected to the first recording unit 803 and the second recording unit 804. Among them, the first recording unit 803 is used to record the number of times the active valve 908 is opened, and the liquid level value of the waste in the first cavity 116 before each opening of the active valve 908; the second recording unit 804 is used to record the number of times the active valve 908 is opened, and the liquid level value of the waste in the first cavity 116 after the active valve 908 is closed again after each opening; the arithmetic unit 805 is used to calculate the liquid level value of the waste transferred into the second cavity 117 according to the values recorded by the first recording unit 803 and the second recording unit 804. The first recording unit 803 and the second recording unit 804 can be a unified component or device physically. The principle is that the first cavity 116 serves as a buffer storage container. Due to its small volume, it can provide more accurate negative pressure and a more intuitive visual effect, and at the same time can provide more accurate measurement scales. When the volume of the waste in the first cavity 116 as the buffer storage container reaches the preset volume, the valve controller 801 controls the active valve 908 to connect the first cavity 116 and the second cavity 117, and in the state where the first cavity 116 and the second cavity 117 are connected, the valve controller 801 controls the active valve 908 to perform an evacuation action. When the waste in the first cavity 116 is completely transferred, the valve controller 801 controls the active valve 908 to isolate the first cavity 116 and the second cavity 117. In order to ensure that the waste can be completely transferred, the time of the evacuation action can be set to avoid leaving waste in the first cavity 116. Or as Figure 13 shown, after the valve controller 801 controls the active valve 908 to isolate the first cavity 116 and the second cavity 117, the liquid level value in the first cavity 116 is obtained again, that is, the difference between the liquid level value of the first cavity 116 before the active valve 908 connects the first cavity 116 and the second cavity 117 and the liquid level value of the first cavity 116 after the active valve 908 isolates the first cavity 116 and the second cavity 117 is the volume of the waste discharged into the second cavity 117.

[0069] After all the waste in the first cavity 116 is discharged into the second cavity 117

[0070] Specifically, refer to Figure 14 the above-mentioned liquid level measurement method for waste, including:

[0071] Step S110, obtaining the liquid level value of the waste in the first cavity 116 of the waste collection container 109;

[0072] Step S120, after opening the active valve 908 of the first cavity 116 and the second cavity 117 of the waste collection container 109, obtain the liquid level of the waste discharged into the second cavity 117 according to the liquid level value of the waste in the first cavity 116.

[0073] See Figure 15 As shown, further, step S120 specifically includes:

[0074] Step S121, record the number of times the active valve 908 is opened and the liquid level value of the waste in the first cavity 116 before each opening of the active valve 908;

[0075] Step S122, the active valve 908 performs an evacuation action;

[0076] Step S123, record the number of times the active valve 908 is opened and the liquid level value of the waste in the first cavity 116 after the active valve 908 is closed again after each opening;

[0077] Step S124, calculate the liquid level value of the waste transferred into the second cavity 117.

[0078] The principle of the above method is as described above and will not be elaborated here.

[0079] In this embodiment, the vacuum source 150 is arranged inside the waste collection device 100. In other embodiments, the vacuum source 150 can be an external device. See Figure 8 , through the fluid transmission pipeline 942 connected to the fluid delivery hole 912, transport the waste sucked by the suction pipeline and passing through the consumable cartridge 300 into the first cavity 116 of the waste collection container 109. The suction hole 911 is connected to the vacuum source 150 through the vacuum short pipe 941, the consumable cartridge 300, and the vacuum connection pipe 125 in an air path. The cleaning access hole 913 is connected to the cleaning pipeline 124 through the end inlet 904 of the cleaning two-way joint 939.

[0080] See Figure 3 , the first cavity 116 is provided with a first cover 920, and the fluid delivery hole 912, the suction hole 911, and the cleaning access hole 913 are arranged on the first cover 920. In other embodiments, the fluid delivery hole 912 and the suction hole 911 can be the same hole to multiplex the functions of fluid delivery and suction gas.

[0081] See Figure 6 and Figure 10 , the first cavity 116 is provided with a first air path through hole 914, and the second cavity is provided with a second air path through hole 924. See Figure 5, a gas connection pipe 923 is provided between the first gas passage through-hole 914 and the second gas passage through-hole 924. After connecting the first gas passage through-hole 914 and the second gas passage through-hole 924 through the gas connection pipe 923, the vacuum source 150 can simultaneously provide suction force for both the first cavity 116 and the second cavity 117, so that even when the movable valve 908 closes and disconnects the first cavity 116 and the second cavity 117, a negative pressure state can be formed in the second cavity 117, avoiding the positive pressure in the first cavity 117 impacting the negative pressure in the first cavity 116 due to the failure to aspirate the second cavity 117 when the first cavity 116 and the second cavity 117 are first connected. This may not only cause the waste in the first cavity 116 to vibrate and not flow into the second cavity 117 immediately, but also result in unstable negative pressure during the suction process, requiring the air in the waste collection container 109 to be aspirated again to form a stable negative pressure. Therefore, by providing the first gas passage through-hole 914 and the second gas passage through-hole 924 and connecting their gas paths through a gas connection pipe 923, the suction process can be made smoother. The first cavity 116 is located above the second cavity 117. Therefore, when the first cavity 116 and the second cavity 117 are closed, since a negative pressure has been formed in the second cavity 117, when the movable valve 908 is opened, the waste in the first cavity 116 can be discharged into the second cavity 117 more smoothly and quickly under its own weight and the negative pressure in the second cavity 117.

[0082] Meanwhile, the volume of the first cavity 116 is smaller than that of the second cavity 117. Preferably, the volume of the first cavity 116 is 5 - 10 liters, and the volume of the second cavity 117 is 10 - 30 liters. In this embodiment, both the first cavity 116 and the second cavity 117 are cylindrical, and the diameter of the first cavity 116 is smaller than that of the second cavity 117. The first cavity 116 and the second cavity 117 may have a common central axis, as Figures 2 - 9 shown; the first cavity 116 and the second cavity 117 may also have a non-common central axis structure as shown in Figure 9 and Figure 10 .

[0083] See Figure 7 、 Figure 9 and Figure 11As shown in the figure, the movable valve 908 includes an actuating component 930 disposed at the top of the first cavity 116, a movable rod 931 with one end connected to the actuating component 930, and a movable valve leaf 932 disposed at the other end of the movable rod 931; the movable valve leaf 932 can move between a first position and a second position under the drive of the actuating component 930 by the movable rod 931; when the movable valve leaf 932 is in the first position, the first cavity 116 and the second cavity 117 are in a closed state; when the movable valve leaf 932 is in the second position, the first cavity 116 and the second cavity 117 are in a communicating state. The second position of the movable valve leaf 932 is preferably within the second cavity 117, see Figure 7 , specifically, the actuating component 930 pushes the movable rod 931 downward. In other embodiments, the actuating component 930 can pull the movable rod 931 upward to make the movable valve leaf 932 enter the first cavity 116 to achieve the communication between the first cavity 116 and the second cavity 117. Preferably, the actuating component 930 is a stepper motor, or other push-pull devices and mechanisms. Wherein the second position is within the first cavity 116, that is, when it is necessary to communicate the first cavity 116 and the second cavity 117, the movable valve leaf 932 moves upward from the first position isolating the first cavity 116 and the second cavity 117 into the first cavity 116 to communicate the first cavity 116 and the second cavity 117.

[0084] In this embodiment, the movable valve leaf 932 can reciprocate between a third position and a fourth position under the drive of the actuating component 930 by the movable rod 931 to form a discharging action. That is, when it is necessary to transfer the waste in the first cavity 116 to the second cavity 117, the valve controller 801 controls the movable valve 908 to communicate the first cavity 116 and the second cavity 117, and in the state where the first cavity 116 and the second cavity 117 are communicated, the valve controller 801 controls the movable valve 908 to perform a discharging action. Specifically, the movable valve leaf 932 reciprocates up and down within the first cavity 116, the fourth position is above the third position, the third position is above the first position, the distance between the fourth position value and the third position can be adjusted as needed, and the distance between the fourth position value and the third position can be set according to requirements. During this process, when the movable valve leaf 932 moves from the fourth position to the third position, a driving force is formed, and this driving force can accelerate the transfer of the waste in the first cavity 116 to the second cavity 117.

[0085] In this embodiment, the trigger for the transfer of the waste in the first cavity 116 to the second cavity 117 can be a manual operation, such as clicking the corresponding operation instruction on the collection end display screen 103 or a separately provided mechanical button, or it can be automatically triggered when the waste in the first cavity 116 reaches a certain liquid level.

[0086] The dividing partition wall 902 serves as the bottom of the first cavity 116 and also as the top of the second cavity 117. In this embodiment, since the diameter of the first cavity 116 is smaller than that of the second cavity 117, only a part of the dividing partition wall 902 serves as the bottom of the first cavity 116, and the second gas path through hole 924 can be arranged in the part of the dividing partition wall 902 that does not serve as the bottom of the first cavity 116. At the same time, the dividing partition wall 902 is provided with a fluid communication hole 905, and the fluid communication hole 905 cooperates with the movable valve leaf 932 to connect or close the first cavity 116 and the second cavity 117. In order to increase the flow rate, the aperture of the fluid communication hole 905 can be increased, and at the same time, the area of the movable valve leaf 932 can be increased to form a greater driving force.

[0087] See Figure 11 , the movable valve 908 further includes a sealing rubber ring 936, and the sealing rubber ring 936 is arranged on the movable valve leaf 932. Specifically, a groove is formed on the movable valve leaf 932, and the sealing rubber ring 936 is embedded in the groove. In other embodiments, the sealing rubber ring 936 can also be embedded in the fluid communication hole 905 in the same manner. At the same time, a plurality of support and guide pieces 937 that can be clamped into the fluid communication hole 905 are arranged on the movable valve leaf 932. The support and guide pieces 937 can guide the movable valve leaf 932 into the fluid communication hole 905, and the waste fluid can flow out between the support and guide pieces 937.

[0088] See Figures 6 - 11 , a second cover body 920 for passing through the movable rod 931 is installed on the first cover body 901. The second cover body 920 is a detachable structure, which is convenient for the installation, disassembly and maintenance of the movable valve 908. A liquid level measuring instrument 921 is also arranged in the first cavity 116. Specifically, the liquid level measuring instrument 921 is inserted through the first measuring hole 915 on the first cover body 901.

[0089] See Figure 9 , the movable rod 931 includes a cleaning inner cavity 935, and the cleaning inner cavity 935 is connected to the second collection end joint through a cleaning pipeline 124. Specifically, the cleaning pipeline 124 is connected through the end inlet 904 of the cleaning two-way joint 939, and the cleaning liquid can enter the cleaning inner cavity 935 through the above pipeline.

[0090] The movable rod 931 passes through the cleaning access hole 913, see Figure 11, the movable rod 931 further includes: at least one first cleaning nozzle 933 for cleaning the first cavity 116, the first cleaning nozzle 933 communicating with the cleaning inner cavity 935; at least one second cleaning nozzle 934 for cleaning the second cavity 117, the second cleaning nozzle 934 communicating with the cleaning inner cavity 935. The first cleaning nozzle 933 and the second cleaning nozzle 934 are rotatable nozzles, and a plurality of nozzles are provided on the rotatable nozzle, and spray holes in different directions are provided on each nozzle, so as to realize the cleaning of different angles and positions of the first cavity 116 and the second cavity 117.

[0091] Implementing the embodiments of the present invention has the following beneficial effects:

[0092] First of all, in the waste collection device in the embodiments of the present invention, by dividing the waste collection container into two cavities that can communicate and be separated, it is possible to use containers with different volumes for different treatment plans to suck and store waste. Moreover, it is considered that the remaining capacity can be more intuitively estimated during observation to ensure the manual control of the operation, and the total storage volume of the waste collection container can be ensured through the two cavities, thereby avoiding the interruption of the operation caused by emptying the waste collection container during the operation.

[0093] Secondly, the waste collection container in this embodiment is installed and used as a whole, without the need to use too many devices to realize the series connection of multiple waste collection containers, and it is also more convenient to install, clean and maintain;

[0094] Furthermore, by recording the liquid level in the first cavity and the number of times the movable valve is opened, the liquid level of the waste discharged into the second cavity can be accurately calculated without separately setting a liquid level measuring device in the second cavity, reducing the material cost and process cost of the waste collection device.

[0095] The above-disclosed is only a preferred embodiment of the present invention, and of course it cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
