Abstract
Description
Technical Field
[0001] The invention relates to a waste collection device and a waste collection and treatment system, which are used for collecting and treating waste materials generated in a medical process. Background Art
[0002] During certain surgical procedures, liquid, semi-solid and solid wastes are inevitably generated, including body fluids such as blood and perfusion solutions introduced into the surgical site during surgery. Solid and semi-solid wastes generated during surgery include tissue fragments and small pieces of surgical materials that may remain in the body. Ideally, wastes should be collected as soon as they are generated so that they do not contaminate the surgical site or become biohazards in the operating room or other places where the surgical procedure is performed.
[0003] In the prior art, there are a variety of waste collection and treatment systems for medical staff to collect waste generated during surgery during or after surgery. The principle is mainly to generate 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, thereby sucking the waste into a specific collection container through the pipeline contacted by the surgical site. In the medical waste collection and treatment system, the waste material is 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 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 waste; at the same time, usually during the medical process, medical staff need to scan the waste collection container to estimate the amount of waste to be extracted later, so as to control the operation, but the larger the capacity of the container, the worse the intuitiveness of the volume, which is not conducive to estimation. However, when using a small container, although it is easy to predict intuitively, the container will be filled up faster, which will cause the operation process to be interrupted to empty the waste collection container. The middle of the operation process 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 operation.
[0004] In order to solve this technical problem, it is proposed to use a waste collection container with two chambers of different volumes, using the small-volume chamber to achieve intuitive estimation and accurate measurement, and using the large-volume chamber to achieve storage of large amounts of waste. However, in this technical solution, since both chambers are connected to the same negative pressure source, in the operation of transferring the waste from the small chamber to the large chamber, the pressure of the two is the same, and the transfer method through gravity is slow. However, since many surgeries cannot be delayed, this technical solution will have a very adverse effect when performing certain surgeries; for other surgeries, the slow transfer speed will also greatly affect the progress and fluency of the surgery, causing many inconveniences to patients and medical staff. Summary of the invention
[0005] The technical problem to be solved by the embodiments of the present invention is to provide a device that can accurately estimate and calculate the volume of waste, and can select different storage volumes for execution according to different treatment plans, and the speed of waste transfer between containers of different storage volumes will not affect the progress of the operation.

[0013] Furthermore, the movable valve leaf can reciprocate between the third position and the fourth position driven by the actuating component according to the movable rod to form an emptying action.
[0014] Furthermore, the partition wall is provided with a fluid communication hole, and the fluid communication hole cooperates with the movable valve leaf to connect or close the first cavity and the second cavity.
[0015] Furthermore, the movable valve also includes a sealing rubber ring, which is arranged on the movable valve leaf or in the fluid communication hole.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0039] like Figure 1-Figure 4 As shown, Figure 1 and Figure 2 A waste collection and treatment system 10 is shown, the system comprising a waste collection device 100 and a docking device 200, Figure 1 The waste collection and treatment system 10 is in a state where the waste collection device 100 and the docking device 200 are not docked. Figure 2 The waste collection and treatment system 10 is a waste collection device 100 and a docking device 200 in a docking state. The waste collection device 100 can be connected to an external suction pipeline (not shown in the figure) through a consumable box 300, and the external suction pipeline can be connected to a suction joint (not shown in the figure), which can be a separate joint or attached to a surgical device. The suction force at the suction joint transports the waste to the waste collection device 100 through the external suction pipeline for storage. After the docking device 200 is docked with the waste collection device 100, the waste in the waste collection device 100 can be emptied through the docking device 200, and 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 repeated here.
[0040] The waste collection device 100 is used in the waste collection and treatment system 10 to collect waste generated during medical treatment and is used to dock with the docking device 200 to discharge the waste.

[0042] See also Figure 3 , Figure 3 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 waste generated by the medical process. In this embodiment, a waste collection container 109 is provided, and the waste collection container 109 has a first cavity 116 and a second cavity 117, wherein 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, which 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 shell 101. Preferably, a corresponding observation window is provided on the collection end shell 101 for observing the waste in the waste collection container 109, such as liquid level or color. In this example, the first observation window 106 and the second observation window 107 are correspondingly provided, which are used to observe the first cavity 116 and the second cavity 117, respectively.
[0043] The mating bracket 110 is mounted on the bottom frame 118 of the portable dolly 108 for mating with the docking device 200. The mating bracket 110 forms a mating space 1100 for accommodating the mating head of the docking device 200.
[0044] Two collecting end connectors 112 and 114 are attached to the matching bracket 110 and are respectively connected to at least one waste collection container 109, wherein one collecting end connector 112 is used to discharge waste in the waste collection container 109, and the other collecting end connector 114 is used to introduce cleaning liquid for cleaning at least one waste collection container 109. In this embodiment, for the sake of distinction, the collecting end connector 112 used for discharging waste in the waste collection container 109 is referred to as the first collecting end connector 112, and the collecting end connector 114 used for introducing cleaning liquid for cleaning the waste collection container 109 is referred to as the second collecting end connector 114. Figure 4 , Figure 4 FIG. 1 is a schematic diagram of the internal structure of the waste collection device of the present invention. Figure 4As shown, the first collecting end joint 112 is connected to the waste collection container 109 through the discharge pipe 122. Specifically, the first collecting 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 collecting end joint 112, and the other end is connected to the bottom of the first cavity 116; the second collecting 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 collecting end joint 114, and the other end is connected to the top of the second cavity 117.
[0045] Two floating sleeves 111, 113 are installed on the matching bracket 110, and are correspondingly sleeved on the two collecting end connectors 112, 114, and are used to guide the two butt-end connectors of the docking device 200 to be correspondingly connected with the two collecting end connectors 112, 114; the two floating sleeves 111, 113 can be suspended and moved relative to the matching bracket 110 and guide the two butt-end connectors to be engaged with the two collecting end connectors 112, 114. When the butt-end connector of the docking device 200 is not connected, the corresponding floating sleeves 111, 113 are in the initial position; in the process of connecting the butt-end connector, the floating sleeves 111, 113 can be suspended and moved relative to the matching bracket 110 and guide the two butt-end connectors to be engaged with the two collecting end connectors 112, 114.
[0046] See also Figure 1-7 In this embodiment, the waste collection device 100 includes:
[0047] A portable trolley 108; a matching bracket 110, the matching bracket 110 is installed on the portable trolley 108, and is used to match with the docking device 200;
[0048] A waste collection container 109, which is mounted on the portable trolley 108 and is used to store waste generated during medical procedures; a first collection end connector 112 and a second collection end connector 114, which are attached to the matching bracket 110 and connected to the waste collection container 109, and are used to discharge waste from the waste collection container 109; and a second collection end connector 114, which is attached to the matching bracket 110 and connected to the waste collection container 109, and is used to introduce a cleaning liquid for cleaning the waste collection container 109;
[0049] 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 also 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 connecting with the vacuum source 150 gas path, and a cleaning access hole 913, and the second cavity 117 is provided with a liquid discharge hole 916;
[0050] The movable valve 908 is disposed on the waste collection container 109 and is used to connect or isolate the first cavity 116 and the second cavity 117;
[0051] See also Fig.12 The valve controller 801 is connected to the movable valve 908. When the waste in the first cavity 116 needs to be transferred 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. When the first cavity 116 and the second cavity 117 are connected, the valve controller 801 controls the movable valve 908 to perform an emptying action. When the waste in the first cavity 116 is transferred, the valve controller 801 controls the movable valve 908 to isolate the first cavity 116 and the second cavity 117. In this embodiment, the valve controller 801 can be integrated under the display 103 at the collection end.
[0052] In this embodiment, the vacuum source 150 is disposed in the waste collection device 100. In other embodiments, the vacuum source 150 may be an external device. Figure 8 , the waste sucked by the suction pipeline and passing through the consumable box 300 is transported to the first cavity 116 of the waste collection container 109 through the fluid transmission pipeline 942 connected to the fluid delivery hole 912. The suction air hole 911 is connected to the vacuum source 150 through the vacuum short tube 941, the consumable box 300, and the vacuum connecting pipe 125. The cleaning access hole 913 is connected to the cleaning pipeline 124 through the end inlet 904 of the cleaning two-way joint 939.
[0053] See also 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 provided on the first cover 920. In other embodiments, the fluid delivery hole 912 and the suction hole 911 can be the same hole to reuse the functions of fluid delivery and gas suction.
[0054] See also Figure 6 and Fig.10 The first cavity 116 is provided with a first gas path through hole 914, and the second cavity is provided with a second gas path through hole 924, see Figure 5, the first gas path through hole 914 and the second gas path through hole 924 are connected by a gas connection pipe 923. After the first gas path through hole 914 and the second gas path through hole 924 are connected by the gas connection pipe 923, the vacuum source 150 can provide suction force for the first cavity 116 and the second cavity 117 at the same time, so that even if the movable valve 908 closes the first cavity 116 and the second cavity 117 and does not connect, a negative pressure state can be formed in the second cavity 117, so as to avoid the positive pressure in the first cavity 117 impacting the negative pressure in the first cavity 116 due to the failure to suction the second cavity 117 when the first cavity 116 and the second cavity 117 are connected for the first time, which may not only cause the waste in the first cavity 116 to vibrate and fail to flow into the second cavity 117 immediately, but also cause the negative pressure in the suction process to be unstable, and the air in the waste collection container 109 needs to be sucked again to form a stable negative pressure. Therefore, by providing the first gas path through hole 914 and the second gas path through hole 924, and providing a gas connecting pipe 923 between the two to make the gas path connected, 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 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 the self-weight and the negative pressure in the second cavity 117.
[0055] 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, the first cavity 116 and the second cavity 117 are both 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, such as Figure 2-Figure 9 As shown; the first cavity 116 and the second cavity 117 can also be as Fig. 9 and Fig.10 Structures with no common central axis are shown.
[0056] See also Figure 7 , Fig. 9 as well as Fig.11As shown, the movable valve 908 includes an actuating component 930 disposed at the top of the first cavity 116, a movable rod 931 connected to the actuating component 930 at one end, 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 driven by the actuating component 930 according to 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 connected state. The second position of the movable valve leaf 932 is preferably in 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 allow the movable valve leaf 932 to enter the first cavity 116 to achieve the connection between the first cavity 116 and the second cavity 117. Preferably, the actuating component 930 is a stepping motor, or other push-pull devices and mechanisms. The second position is in the first cavity 116, that is, when the first cavity 116 and the second cavity 117 need to be connected, 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 connect the first cavity 116 and the second cavity 117.
[0057] In this embodiment, the movable valve leaf 932 can reciprocate between the third position and the fourth position driven by the actuating member 930 according to the movable rod 931 to form an emptying 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 connect the first cavity 116 and the second cavity 117, and the valve controller 801 controls the movable valve 908 to perform an emptying action when the first cavity 116 and the second cavity 117 are connected. Specifically, the movable valve leaf 932 reciprocates up and down in the first cavity 116, the fourth position is above the third position, and 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 as needed. In this process, the movable valve leaf 932 forms a driving force when it moves from the fourth position to the third position, and the driving force can accelerate the transfer of waste in the first cavity 116 to the second cavity 117.
[0058] In this embodiment, the transfer of the waste in the first cavity 116 to the second cavity 117 can be triggered manually, such as clicking a corresponding operation instruction on the collection end display screen 103 or a separately set mechanical button, or it can be automatically triggered when the waste in the first cavity 116 reaches a certain liquid level.
[0059] The 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 the diameter of the second cavity 117, only a portion of the partition wall 902 serves as the bottom of the first cavity 116, and the second gas path through hole 924 can be provided at the portion of the partition wall 902 that does not serve as the bottom of the first cavity 116. At the same time, the partition wall 902 is provided with a fluid communication hole 905, which 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.
[0060] See also Fig.11 The movable valve 908 further includes a sealing rubber ring 936, which is disposed 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, the movable valve leaf 932 is provided with a plurality of support guide pieces 937 that can be inserted into the fluid communication hole 905. The support guide pieces 937 can guide the movable valve leaf 932 to enter the fluid communication hole 905, and waste can flow out between the support guide pieces 937.
[0061] See also Figure 6-Figure 11 The first cover 901 is provided with a second cover 920 for inserting the movable rod 931. The second cover 920 is a detachable structure, which is convenient for the installation, removal and maintenance of the movable valve 908. The first cavity 116 is also provided with a first liquid level measuring instrument 921, and the second cavity 117 is also provided with a second liquid level measuring instrument 922. Specifically, the first liquid level measuring instrument 921 is inserted through the first measuring hole 915 on the first cover 901, and the second liquid level measuring instrument 922 is inserted through the second measuring hole 917 on the partition wall 902.
[0062] See also Fig. 9 The movable rod 931 includes a cleaning inner cavity 935, which is connected to the second collecting 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.
[0063] The movable rod 931 passes through the cleaning access hole 913, see Fig.11The movable rod 931 further includes: at least one first cleaning nozzle 933 for cleaning the first cavity 116, the first cleaning nozzle 933 is connected to the cleaning inner cavity 935; at least one second cleaning nozzle 934 for cleaning the second cavity 117, the second cleaning nozzle 934 is connected to 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 arranged on the rotating nozzles, and each nozzle is provided with spray holes in different directions, so as to realize the cleaning of the first cavity 116 and the second cavity 117 at different angles and positions.
[0064] First, in the waste collection device in the embodiment of the present invention, by dividing the waste collection container into two cavities that can be connected and separated, it is possible to use containers of different volumes to suck and store waste for different treatment plans. In addition, it is believed that the remaining capacity can be more intuitively estimated during observation to ensure human control of the operation, and the total storage volume of the waste collection container can be ensured by the two cavities, thereby avoiding the interruption of the operation caused by the need to empty the waste collection container during the operation.
[0065] Secondly, the waste collection container in this embodiment is installed and used as a whole, and there is no need to use too many devices to achieve the series connection of multiple waste collection containers, which is more convenient to install, clean and maintain;
[0066] Furthermore, the first cavity and the second cavity can realize negative pressure suction of the two cavities through a vacuum source, so that the first cavity discharges waste into the second cavity more smoothly and does not cause pressure fluctuations in the first cavity;
[0067] At the same time, by setting a cleaning inner cavity on the movable rod, the first cavity and the second cavity can be cleaned at the same time of closing and connecting the first cavity and the second cavity, and the structure of the movable valve can be reused to achieve cleaning, thereby saving a special cleaning structure, saving costs and streamlining equipment. At the same time, the push and pull of the movable rod can achieve cleaning at different positions;
[0068] Furthermore, the emptying action of the piston valve makes it possible to transfer waste between the two connected and separated cavities more quickly, thereby not delaying the progress and time of the operation and making the surgical treatment smoother and more successful.
[0069] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
