Butt joint equipment and waste liquid collecting and treating system

Technical Field

The utility model relates to a docking facility and waste liquid collection processing system that is used for with the butt joint of the waste liquid collecting device of collecting and handling the waste liquid material that produces among the medical process.

Background

During the performance of a particular surgical procedure, liquid, semi-solid and solid waste fluids, including in particular body fluids, such as blood, and perfusion solutions introduced into the surgical site during the procedure, are inevitably produced, and in addition, solid and semi-solid waste fluids produced during the procedure include tissue fragments and small pieces of surgical material that may remain in the body site. Ideally, the waste fluid is collected once it is produced 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 fluid collection and treatment systems available for medical personnel to collect waste fluids generated during a procedure after or after the procedure has been performed. The principle is mainly that waste liquid generated at the operation site is sucked into a specific collection container by the suction force generated by a vacuum source. That is, upon system activation, the suction force generated by the vacuum source reaches the surgical site, drawing waste fluid through the tubing that the surgical site contacts into a specific collection container.

In the prior art, in medical waste collection and treatment systems, waste materials are collected in a waste collection container connected to a vacuum source, and the waste collection container is generally mounted on a portable trolley with wheels for easy transportation. Generally, during pumping, when the storage volume of the waste collection container reaches a predetermined volume, it is necessary to empty the waste collection container, and earlier prior art has been to push the waste collection device to a docking station and empty and clean it. The waste collection unit begins emptying after docking to the docking station and once emptied, the waste collection container is cleaned by the cleaning system by disinfection and washing. In a series of medical procedures, each procedure requires emptying, and the frequent operation of pushing the waste fluid collection device to the docking station each time causes inconvenience to the user and affects the medical schedule. Therefore, in response to this technical drawback, a transfer device dedicated to transporting waste liquid of a waste liquid collecting device to a docking station has been developed, i.e. a docking device dedicated to transporting waste liquid in a waste liquid collecting device, which device usually comprises two connectors for docking with two connectors of the waste liquid collecting device to form a liquid path communication, one liquid path for transferring waste liquid of the waste liquid collecting device to the docking device, and the other liquid path for cleaning a waste liquid collecting container of the waste liquid collecting device. Before the docking device flushes the waste liquid collecting device, it is necessary to confirm that the waste liquid in the waste liquid collecting device is emptied, and in the prior art, whether the docking device empties the waste liquid in the waste liquid collecting device is confirmed by placing a ball float valve in the waste liquid collecting container of the waste liquid collecting device or installing a detection sensor in the waste liquid collecting container, see US200501887529a1 and US 7879228. I.e. either the float valve or the level sensor, needs to transmit data to the docking device via the electronics in the waste collection device to initiate flushing of the waste collection device by the docking device.

The prior art detection sensor has the following disadvantages: float valve or other prior art's level sensor all need put into or install in waste liquid collection container, and need contact with the waste liquid, and need the trompil during this structural installation, it is very inconvenient to the installation of integrated into one piece's waste liquid collection container, simultaneously if put into waste liquid collection container then can influence container intensity and sealed effect, and the installation is complicated and installation cost is high, and float valve among the prior art and other contact level sensor receive the waste liquid easily, the corruption of washing liquid and antiseptic solution, and receive the influence of incrustation scale easily, short-lived and unable change and maintenance, these all can cause the use cost of equipment to increase by a wide margin. Simultaneously, because this detection sensor is direct to be connected with the waste liquid collection container, consequently when waste liquid collection equipment and butt joint equipment dock, waste liquid collection equipment must circular telegram just can be with the data transmission to the butt joint equipment of detection sensor, and this operation can cause the sky of waste liquid collection equipment to open, causes the influence to the electrical part, needs operate the waste liquid sensor simultaneously, brings inconvenience for the user. In addition, in the case of a waste liquid collecting device having a plurality of waste liquid collecting containers, it is necessary to detect whether the liquid in each waste liquid collecting container is emptied, and in the prior art, a detection sensor is installed for each waste liquid collecting container, see the patent of US7879228, and for the device having a plurality of waste liquid collecting containers, the prior art solution increases the amount of sensors used, which leads to an increase in manufacturing cost.

The negative pressure port 1092 of the waste liquid collecting container 109 is connected to a negative pressure source 461 through a negative pressure air passage 460, and the negative pressure source 461 may be disposed in the waste liquid collecting apparatus 100 or may be an external negative pressure source.

As shown in fig. 5, the docking device 200 is used in the waste fluid collecting and treating system 10 to discharge waste fluid generated in the medical procedure of the waste fluid collecting device 100 in the waste fluid collecting and treating system 10, and the docking device 200 comprises: suction connection 212, liquid feed connection 214, liquid discharge pump 421, detection device 430, and control unit 500. The suction fitting 212 interfaces with the drain fitting 112 of the waste collection device 100 to form a drain line 420 that drains liquid within the waste collection container 109 of the waste collection device 100; the liquid feeding joint 214 is butted with a liquid inlet joint 114 of the waste liquid collecting device 100 to form a cleaning pipeline 440 for injecting liquid into the waste liquid collecting device 100 to clean the waste liquid collecting container 109; a drain pump 421 disposed in the drain line 420 for draining the liquid in the waste liquid collecting container 109 through the drain line 420 after the drain process is started; the detection device 430 is used for detecting whether liquid passes through a part of the discharge pipeline 420 in the docking apparatus 200, and the detection device 430 is not in direct contact with the waste liquid collection container 109; when the detection device 430 detects no liquid, the control unit 500 controls the filling of liquid into the cleaning line 440 to perform a cleaning operation on the waste liquid collection container 109. In this embodiment, the drainage program is a drainage logic executable by the apparatus, and may be automatically triggered or manually triggered, where the automatic triggering may be automatically started after the waste liquid collecting apparatus 100 and the docking apparatus 200 are docked, or manually started through a touch screen or an operation key. The liquid drainage process is mainly to drain the liquid in the waste liquid collection container 109 through the drain line 420 by the liquid drainage pump 421, and after the liquid drainage process is started, the cleaning line is in a closed state. The drain line 420 terminates in a drain port 421, wherein a drain control valve 422 is also provided between the drain pump 421 and the drain port 423 for closing or opening the drain port 423. The discharge port 423 may be a hose connector directly connected to the drain passage, or a connector to which a hose can be connected, such as the discharge connector 208 shown in fig. 4, and may be discharged through the discharge port 423 connected to an additional sewage drain. In this embodiment, the waste liquid collecting container 109 may have a single-chamber structure as shown in fig. 5, a multi-chamber structure including a first inner chamber 116 and a second inner chamber 117 that can be communicated and isolated from each other as shown in fig. 3 and fig. 5-8, or may include a plurality of collecting containers 109.

In this embodiment, the detection device 430 is located at a portion of the discharge line 420 between the suction connector 212 and the drain pump 421, which portion is close to the suction connector 212. That is, after the waste liquid collecting apparatus 100 and the docking apparatus 200 are docked, the detection device 430 is disposed at a position close to the liquid discharge port 1093 of the waste liquid collecting apparatus 100, so that whether liquid passes through the discharge pipe 420 can be detected at the first time, and the idle time of the liquid discharge pump 421 can be minimized. The detecting device 430 may be a non-contact water sensing sensor, and the detecting device 430 in this embodiment is a non-contact water sensing sensor (liquid level sensing switch), and the working principle of the sensor is as follows: the liquid level sensor is characterized in that the sensing capacitor of water is used for detecting whether liquid exists or not, when no liquid is close to the sensor, a certain static capacitor exists on the sensor due to the existence of distributed capacitors, when the liquid level slowly rises to be close to the sensor, the parasitic capacitor of the liquid is coupled to the static capacitor, the final capacitance value of the sensor is increased, the changed capacitance signal is input to a control chip for signal conversion, the changed capacitance is converted into the variation of a certain electric signal, the degree of the variation is detected and judged by a preset algorithm, and when the variation exceeds a certain threshold value, the liquid level is considered to reach a sensing point. The non-contact water induction sensor breaks through the influence of the wall thickness of the container, and realizes non-contact detection of the height of the liquid level in the closed container. Referring to fig. 9, the detection device 430 is disposed outside the discharge pipe 420, preferably, is closely attached to the outer wall of the discharge pipe 420, and may be adhered, welded or bound to the outer wall of the discharge pipe 420. The non-metal container does not need to be perforated, is easy to install and does not influence production. The liquid level detection device can detect various toxic substances, strong acid, strong base and various liquids in the high-pressure closed container. In other embodiments, the detection device 430 may be a non-contact water-sensing sensor, and besides, the detection device 430 may also be other types of sensors that are not in contact with the liquid, such as a correlation type photoelectric sensor.

Specifically, referring to fig. 6, fig. 6 is a schematic liquid drainage diagram of the docking apparatus 200 and the waste liquid collecting apparatus 100, after the liquid drainage procedure is started, the liquid drainage pump 421 operates to suck the liquid in the waste liquid collecting container 109 and discharge the liquid through the discharge pipe 420 in the direction of the arrow shown in fig. 6, at this time, the liquid passes through the discharge pipe 420, and the detection device 430 feeds back a signal indicating that the liquid passes through the sensing point. When the liquid in the waste liquid collecting container 109 is emptied, and no liquid passes through the discharge line 420, the detecting device 430 cannot detect the liquid, and a signal indicating that no liquid passes through the sensing point is fed back. At this time, the control unit 500 determines that the liquid in the waste liquid collecting container 109 is empty according to the signal that no liquid passes through the sensing point, controls to turn off the liquid discharge pump 421 and to close the liquid discharge path 420, and controls to fill the liquid into the cleaning pipe 440 to perform the cleaning operation on the waste liquid collecting container 109. Referring to fig. 5 and 8, fig. 8 is a flushing schematic diagram of the docking apparatus 200 and the waste liquid collecting apparatus 100, when the water control valve 447 is controlled to open, and a liquid for cleaning is introduced, the liquid is from a tap water pipeline, and is specifically connected with tap water through a water inlet 448 (the water inlet 448 may be the interface 207 shown in fig. 4), and the flushing head 1095 is driven by the pressure of the tap water according to the arrow direction shown in fig. 8 to flush the inner wall of the waste liquid collecting container 109 through the flushing pipeline 440. The water inlet 448 can also be connected directly to the washing pump to generate the flushing pressure. Further, referring to fig. 5 and 8, the docking apparatus 100 further includes a priming pump 443, the priming pump 443 is connected to the cleaning pipeline 440, and is used for injecting a cleaning liquid 445 into the waste liquid collecting container 109 in the direction of the arrow shown in fig. 8 to clean the waste liquid collecting container 109 after the control unit 500 controls the cleaning operation, wherein the cleaning liquid 445 is stored in the liquid container 441, and the cleaning liquid 445 may be a cleaning agent or a mixed liquid of the cleaning agent and the disinfectant.

Since the liquid is not immediately filled in the discharge pipe 420 when the liquid discharge pump 421 is just started, if the detection device 430 is sensitive, a signal indicating that no liquid passes through the sensing point is fed back, and the control unit 500 controls to stop the liquid discharge pump 421, and the liquid discharge process is stopped when the liquid in the waste liquid collection container 109 is not discharged. In order to solve the problem that the detection device 430 is too sensitive to cause the drain pump to be turned off before draining, the detection device 430 may be turned on after a first preset time elapses after the draining process is started, that is: the first preset time detection device 430 does not operate after the drain pump 421 is activated, the detection device 430 is turned on after the liquid flows through the drain pipe 420 after the first preset time, at this time, the liquid flows through the drain pipe 420, the detection device 430 feeds back a signal indicating that the liquid flows through the sensing point, and the drain pump 421 continues to perform the drain process until the liquid in the waste liquid collection container 109 is drained. Alternatively, after the detection device 430 feeds back to the control unit 500 after starting the liquid discharge procedure, the control unit 500 ignores the feedback of the detection device 430 within the first preset time, which can also solve the problem that the liquid discharge pump is shut down before liquid discharge due to the fact that the detection device 430 is too sensitive. The first preset time may be calculated or estimated according to the distance from the detection device 430 to the liquid outlet 1093 of the waste liquid collection container 109, the pipe diameter of the discharge pipe 420, and parameters of the liquid discharge pump 421.

In this embodiment, after the washing operation of the waste liquid collecting container 109 is completed, the liquid generated by the washing is stored in the waste liquid collecting device 109, and the liquid generated by the washing needs to be drained. At this time, the drainage procedure can be automatically restarted to drain the liquid generated by the flushing in the waste liquid collecting device 109, and the process is as described above and will not be described again.

In addition, in this embodiment, the waste liquid collection container 109 may be washed for multiple times to meet the requirement of cleanliness, and the number of times of washing may be set according to the amount of waste liquid, or may be built in the program. When the washing operation is carried out for a plurality of times, the liquid drainage program is automatically started after the washing operation is finished every time. In this process, the control unit 500 is also configured to count the number of times the waste liquid collection container 109 is flushed, and stop the waste liquid treatment when a preset number of flushes is reached and the liquid in the final waste liquid collection container 109 is discharged.

first, the detection device in this embodiment is mounted to the docking device without being directly mounted to the waste liquid collection device and without being physically connected to the waste liquid collection container, so that it is not necessary to additionally open a hole or add an additional accessory to the waste liquid collection container, which can greatly reduce the difficulty of installation, maintenance and replacement and reduce the costs of installation, maintenance and replacement;

thirdly, as the detection device is only installed in the re-docking equipment, in most cases, when the waste liquid in the waste liquid collection equipment is discharged, the waste liquid collection equipment is not required to provide data of the liquid amount in the waste liquid collection container, and the waste liquid collection equipment and the docking equipment are not required to be electrically connected or signal transmission, so that the waste liquid collection equipment is not required to be electrified, the waste liquid collection equipment is not required to be operated, and only the waste liquid collection equipment and the docking equipment are required to be docked, so that the operation of a user is facilitated;

fourthly, since the detection device is arranged outside the waste liquid collection container, the waste liquid collection device can be manufactured by integral forming, and the sealing performance and the strength are enhanced;

fifthly, for the waste liquid collecting device with a plurality of waste liquid collecting containers or a multi-cavity waste liquid collecting container, the detection of the liquid in the plurality of waste liquid collecting containers or the multi-cavity waste liquid collecting container can be completed only by installing one detection device on the butt joint device, the number of accessories is reduced, the equipment cost is reduced, internal wiring is reduced, and the installation process is simplified.
