Description

Waste collecting device

Technical Field

The utility model relates to a waste collecting device, which is used for collecting and treating waste materials generated in the medical process.

Background

In the implementation of a particular surgical procedure, liquid, semi-solid and solid waste of the type that inevitably includes body fluids, such as blood, and perfusion solutions introduced to the surgical site during the procedure, and solid and semi-solid waste generated during the procedure includes tissue fragments and small pieces of surgical material that may remain in the body site. Ideally, the waste material, once generated, is collected so that it does not contaminate the surgical site or become a biohazard to the operating room or other site where the surgical procedure is performed.

In the prior art, there are a variety of waste collection and disposal systems available for medical personnel to collect waste generated during a procedure after the procedure has been performed or after the procedure has been performed. The principle is mainly that the waste generated at the operation site is sucked into a specific collection container by the suction force generated by a vacuum source. That is, after the system is activated, the suction force generated by the vacuum source reaches the surgical site, thereby drawing waste through the tubing that the surgical site contacts into a specific collection container. In a medical waste collection and processing system, waste material is collected in a waste collection container connected to a 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 precision of the scale, which is not favorable for accurately calculating the volume of the waste; meanwhile, in the medical process, medical staff need to scan the waste collection container to estimate the amount of the subsequently extracted waste, so as to control the operation, but the larger the volume of the container, the worse the volume intuitiveness is, and the estimation is not facilitated. However, when a container with a small volume is directly used, although it is easy to visually predict, the container will fill up more quickly, which may lead to interruption of the surgical procedure to empty the waste collection container, and the middle of the surgical procedure may cause inconvenience and risk to the treatment. While both large and small containers have the disadvantage of not being able to select different volumes to perform depending on the type of procedure.

In order to solve the technical problem, the waste collection container which adopts two chambers with different volumes is provided, the intuitive estimation and accurate measurement are realized through the chamber with small volume, and the storage of a large amount of waste is realized through the chamber with large volume. However, in the technical scheme, because the two chambers are both communicated with the same negative pressure source, in the operation of transferring the waste in the small chamber to the large chamber, because the pressure of the two chambers is the same, the speed is slower through a self-flowing transfer method, but because many operations cannot be delayed, the technical scheme can bring very adverse effects when some operations are performed; for other operations, the transfer speed is slow, so that the progress and smoothness of the operation are greatly influenced, and inconvenience is brought to patients and medical staff.

Just because the speed of transferring the waste from the small chamber to the large chamber is slow and the waste is not transferred thoroughly, the liquid level measurement of the waste in the two chambers of the waste collection container in the prior art can only adopt two different liquid level measuring instruments to respectively measure the two chambers. Firstly, the high-precision liquid level measuring instrument is expensive in cost, secondly, the waste collection container needs to be additionally perforated, the process cost is increased, and simultaneously, the structure of the waste collection container is influenced by the larger size of the liquid level measuring instrument.

wherein the waste collection container 109 comprises a first cavity 116 and a second cavity 117; a partition wall 902 is arranged between the first cavity 116 and the second cavity 117; the partition wall 902 is further provided with a movable valve 908 for communicating or closing the first chamber 116 and the second chamber 117; the first chamber 116 is provided with a fluid delivery hole 912 for transferring waste, a suction air hole 911 for air-connecting with the vacuum source 150, and a cleaning access hole 913, and the second chamber 117 is provided with a liquid discharge hole 916;

wherein, the movable valve 908 is disposed in the waste collection container 109 for communicating or isolating the first cavity 116 and the second cavity 117;

referring to fig. 12, the valve controller 801 is connected to the movable valve 908, when the waste in the first chamber 116 needs to be transferred to the second chamber 117, the valve controller 801 controls the movable valve 908 to communicate with the first chamber 116 and the second chamber 117, and the valve controller 801 controls the movable valve 908 to perform an evacuation operation in a state where the first chamber 116 is communicated with the second chamber 117, and after the waste in the first chamber 116 is transferred, the valve controller 801 controls the movable valve 908 to isolate the first chamber 116 from the second chamber 117;

a liquid level measuring instrument 923 disposed in the first chamber 116 for measuring a liquid level of the waste in the first chamber 116; the liquid level processing module 802 is configured to calculate a liquid level of the waste discharged into the second chamber 117 according to the liquid level of the waste in the first chamber 116 obtained by the liquid level measuring instrument 923 after the movable valve 908 is opened. In this embodiment, the valve controller 801 and the fluid level processing module 802 may be integrated under the collection-side display 103.

Referring to fig. 13, the liquid level processing module 802 specifically includes: a first recording unit 803, a second recording unit 804 and an arithmetic unit 805, wherein the arithmetic unit 805 is connected to the first recording unit 803 and the second recording unit 804, respectively.

The first recording unit 803 and the second recording unit 804 may be physically unified elements or devices. The principle is that the first cavity 116 acts as a buffer storage container, which can provide more accurate negative pressure and visual effect due to its small size, and can provide more accurate measurement scale. When the volume of the waste in the first chamber 116 as a buffer storage container reaches a predetermined volume, the valve controller 801 controls the movable valve 908 to communicate with the first chamber 116 and the second chamber 117, and the valve controller 801 controls the movable valve 908 to perform an evacuation operation in a state where the first chamber 116 and the second chamber 117 are communicated, and when the waste in the first chamber 116 is completely transferred, the valve controller 801 controls the movable valve 908 to isolate the first chamber 116 from the second chamber 117. To ensure that the waste is completely transferred, the evacuation action may be timed to avoid the presence of waste in the first chamber 116. Or as shown in fig. 13, after the valve controller 801 controls the movable valve 908 to isolate the first chamber 116 from the second chamber 117, the liquid level value in the first chamber 116 is obtained again, that is, the difference between the liquid level value of the first chamber 116 before the movable valve 908 communicates with the first chamber 116 and the second chamber 117 and the liquid level value of the first chamber 116 after the movable valve 908 isolates the first chamber 116 from the second chamber 117 is the volume of the waste discharged into the second chamber 117.

After all the waste in the first chamber 116 is discharged into the second chamber 117

Specifically, the method for measuring the liquid level of the waste described with reference to fig. 14 includes:

step S110, obtaining a level value of the waste in the first cavity 116 of the waste collection container 109;

in step S120, after the movable valves 908 of the first chamber 116 and the second chamber 117 of the waste collection container 109 are opened, the liquid level of the waste discharged from the second chamber 117 is obtained according to the liquid level value of the waste in the first chamber 116.

As shown in fig. 15, further, step S120 specifically includes:

step S121, recording the number of times the movable valve 908 is opened and the level value of the waste in the first cavity 116 before the movable valve 908 is opened each time;

in step S122, the movable valve 908 performs an evacuation operation;

step S123, recording the opening times of the movable valve 908 and the level value of the waste in the first cavity 116 after the movable valve 908 is closed again after being opened each time;

step S124, calculating a level value of the waste transferred into the second cavity 117.

The principle of the method is as described above and is not described in detail.

In this embodiment, the vacuum source 150 is disposed within the waste collection device 100, and in other embodiments, the vacuum source 150 may be an external device. Referring to fig. 8, waste drawn through the consumable cartridge 300 by the suction line is transported into the first cavity 116 of the waste collection container 109 by a fluid transfer line 942 that is accessed through the fluid transfer aperture 912. The suction hole 911 is connected to the vacuum source 150 via a short vacuum pipe 941, the consumable cartridge 300, and the vacuum connection pipe 125. The purge access hole 913 is connected to the purge line 124 through the end inlet 904 of the purge two-way connector 939.

Referring to fig. 3, the first chamber 116 is provided with a first cover 920, and the fluid transfer hole 912, the suction air hole 911, and the cleaning access hole 913 are provided on the first cover 920. In other embodiments, the fluid delivery port 912 and the suction port 911 may multiplex the functions of fluid delivery and suction for the same port.

Referring to fig. 6 and 10, the first cavity 116 has a first air passage hole 914, and the second cavity has a second air passage hole 924, and referring to fig. 5, the first air passage hole 914 and the second air passage hole 924 are connected by a gas connecting tube 923. After the first air passage hole 914 and the second air passage hole 924 are connected through the air connection pipe 923, the vacuum source 150 can simultaneously provide suction force for the first cavity 116 and the second cavity 117, so that even if the movable valve 908 seals and does not connect the first cavity 116 and the second cavity 117, a negative pressure body can be formed in the second cavity 117, and therefore, when the first cavity 116 and the second cavity 117 are connected for the first time, negative pressure in the first cavity 116 is prevented from being impacted by positive pressure in the first cavity 117 due to non-suction of the second cavity 117, and not only waste in the first cavity 116 may oscillate and cannot flow into the second cavity 117, but also air in the waste collection container 109 needs to be re-sucked to form stable negative pressure due to unstable suction process. Therefore, by providing the first air passage through hole 914 and the second air passage through hole 924 and providing the gas connecting pipe 923 therebetween to communicate the air passages thereof, the pumping process can be smoother. The first chamber 116 is located above the second chamber 117, so when the first chamber 116 and the second chamber 117 are closed, since negative pressure is already formed in the second chamber 117, when the movable valve 908 is opened, the waste in the first chamber 116 can be more smoothly and rapidly discharged into the second chamber 117 under the self-weight and the negative pressure in the second chamber 117.

Meanwhile, the volume of the first cavity 116 is smaller than that of the second cavity 117, and preferably, the volume of the first cavity 116 is 5 to 10 liters, and the volume of the second cavity 117 is 10 to 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 the diameter of the second cavity 117. The first cavity 116 and the second cavity 117 may have a common central axis, as shown in fig. 2-9; the first cavity 116 and the second cavity 117 may also be configured as shown in fig. 9 and 10 in a non-common axis configuration.

Referring to fig. 7, 9 and 11, the movable valve 908 includes an actuating member 930 disposed at the top of the first chamber 116, a movable rod 931 having one end connected to the actuating member 930, and a movable vane 932 disposed at the other end of the movable rod 931; the movable valve vane 932 can move between a first position and a second position under the driving of the actuating component 930 according to the movable rod 931; when the movable valve vane 932 is at the first position, the first cavity 116 and the second cavity 117 are closed; when the movable vane 932 is in the second position, the first cavity 116 is in communication with the second cavity 117. The second position of the movable vane 932 is preferably within the second cavity 117, see fig. 7, with the particular actuating member 930 pushing the movable stem 931 downward. In other embodiments, the actuating member 930 may pull the movable rod 931 upward to allow the movable vane 932 to enter the first cavity 116 to communicate with the first cavity 116 and the second cavity 117. Preferably, the actuation member 930 is a stepper motor, or other push-pull device and mechanism. Wherein the second position is within the first chamber 116, i.e., when communication with the first chamber 116 and the second chamber 117 is desired, the movable flap 932 moves upward into the first chamber 116 from the first position isolating the first chamber 116 and the second chamber 117 to communicate with the first chamber 116 and the second chamber 117.

In this embodiment, the movable vane 932 can reciprocate between the third position and the fourth position to perform an emptying action according to the movable rod 931 driven by the actuating component 930. That is, when it is necessary to transfer the waste in the first chamber 116 to the second chamber 117, the valve controller 801 controls the movable valve 908 to communicate with the first chamber 116 and the second chamber 117, and the valve controller 801 controls the movable valve 908 to perform an evacuation operation in a state where the first chamber 116 and the second chamber 117 communicate with each other. Specifically, the movable valve 932 reciprocates up and down in the first cavity 116, the fourth position is located above the third position, the third position is above the first position, the distance between the fourth position and the third position can be adjusted as required, and the distance between the fourth position and the third position can be set as required. During this process, the movable vane 932 moves from the fourth position to the third position to provide an urging force that accelerates the transfer of waste from the first chamber 116 to the second chamber 117.

In this embodiment, the triggering of the waste in the first cavity 116 to transfer to the second cavity 117 may be manual operation, for example, clicking a corresponding operation instruction on the display screen 103 of the collecting end or a mechanical button separately set up, or may be automatic triggering when the waste in the first cavity 116 reaches a certain liquid level.

The partition 902 acts 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 portion of the partition wall 902 is used as the bottom of the first cavity 116, and the second air passage hole 924 can be disposed on the portion of the partition wall 902 that is not used as the bottom of the first cavity 116. While the partition wall 902 is provided with a fluid communication hole 905, the fluid communication hole 905 cooperates with the movable valve vane 932 to communicate or close the first chamber 116 and the second chamber 117. To increase the flow rate, the hole diameter of the fluid communication hole 905 may be increased while increasing the area of the movable valve vane 932 to create a greater urging force.

Referring to fig. 11, the movable valve 908 further includes a sealing rubber ring 936, and the sealing rubber ring 936 is disposed on the movable valve vane 932, specifically, a groove is formed on the movable valve vane 932, and the sealing rubber ring 936 is embedded in the groove. In other embodiments, the sealing rubber ring 936 can be embedded in the fluid communication hole 905 in the same manner.
