Description

Technical Field

[0001] This invention relates to the field of medical technology, and more particularly to a CRRT waste liquid treatment system. Background Technology

[0002] Continuous renal replacement therapy (CRRT) is defined as a blood purification treatment technique that continuously and slowly removes water and solutes through extracorporeal blood circulation to replace kidney function. Compared to conventional hemodialysis, CRRT prolongs the blood purification treatment time and reduces the treatment efficiency per unit time, minimizing the impact of changes in solute concentration and volume in the blood on the body. It also utilizes highly permeable and biocompatible filters, providing crucial homeostasis for the treatment of critically ill patients.

[0003] In recent years, continuous renal replacement therapy (CRRT) has developed rapidly, from treating patients with single acute renal failure (ARF) to providing combined treatment for patients with various organ failures, ARDS, and sepsis. The indications for CRRT are becoming increasingly broad, leading to a continuous increase in the amount of replacement fluid required and consequently, a corresponding increase in waste fluid production. Currently, hospitals typically collect the waste fluid generated during CRRT treatment using waste bags and then dispose of it in a dedicated wastewater tank. Furthermore, CRRT treatment is generally performed at the bedside, and the wastewater tank is usually some distance away. Nursing staff have to carry the waste bags to the wastewater tank by hand or move them to a treatment cart and then push the cart to the wastewater tank for disposal. This process not only increases the workload of nursing staff but also increases the risk of contaminating the ward. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a CRRT waste liquid treatment system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention designs a CRRT waste liquid treatment system. The user inserts a waste liquid pipe into a compatible adapter, which begins collecting the waste liquid. A suction pump then draws the waste liquid from the adapter through a conduit from a lower position to a higher position, entering the first outlet pipe. The waste liquid then flows into a storage chamber. A second sensor detects the height of the waste liquid in the storage chamber; when a certain height is reached, the second sensor sends a signal, automatically closing the valve and allowing the waste liquid to flow to the next storage chamber. When all storage chambers have reached a set height, a waste liquid collection robot proceeds to the waste liquid treatment base station to empty the waste liquid and recharges. Waste liquid flows from the double-door storage chamber into the outlet chamber. The waste liquid in the outlet chamber flows out of the main body through a second outlet pipe and into the waste liquid treatment base station. The robot can move using omnidirectional wheels. When the robot stops working and the system is shut down, the user uses brake pads to secure the robot and prevent it from moving unnecessarily. Attached Figure Description

[0039] Reference Figures 1 to 3A CRRT waste liquid treatment system includes a waste liquid collection robot 1 for collecting waste liquid from locations where it is required; and a waste liquid treatment base station 2, into which the waste liquid collected by the waste liquid robot 1 is poured. The waste liquid collection robot 1 includes a main body 3, a top cover 4, a collection device 5, a disinfection device 6, and a control board 7. The top cover 4 is fitted onto the main body 3, with one end of the top cover 4 hinged to the main body 3. The main body 3 has several liquid storage chambers 31, which are separated by partitions 32. One end of the collection device 5 is placed on top of the liquid storage chambers 31, and the other end of the collection device 5 passes through the main body 3 and is placed outside the main body 3. The disinfection device 6 and the control board 7 are both placed inside the top cover 4. The disinfection device 6 and the collection device 5 are electrically connected to the control board 7. The disinfection device 6 is used to disinfect the waste liquid inside the main body 3.

[0040] The collection device 5 includes an adapter 51, a suction pump 52, several first outlet pipes 53, and several conduits 54. The suction pump 52 is connected to the conduits 54 at both ends. One end of the adapter 51 is connected to the conduit 54, and the adapter 51 is located outside the main body 3. Several first outlet pipes 53 are connected to the conduits 54, and one first outlet pipe 53 is located above a storage chamber 31. Each first outlet pipe 53 is equipped with an automatic valve 531, and each first outlet pipe 53 has a second sensor 532 on its exterior. The waste liquid collection robot 1 moves to the waste liquid collection site, where the user collects the waste liquid. The liquid pipe is inserted into the adapter 51, and the adapter 51 begins to collect waste liquid. The suction pump 52 starts working and sucks the waste liquid in the adapter 51 from a low position to a high position through the conduit 54, and enters the first outlet pipe 53. From the first outlet pipe 53, it enters the storage chamber 31. The second sensor 532 senses the height of the waste liquid in the storage chamber 31. When a certain height is reached, the second sensor 532 sends a signal, the automatic valve 531 closes, and the waste liquid flows to the next storage chamber 31. When the waste liquid in all storage chambers 31 reaches the set height, the waste liquid collection robot 1 goes to the waste liquid treatment base station 2 to dump the waste liquid.

[0041] Each liquid storage chamber 31 is equipped with a double door 33 at its bottom, and the double door 33 is connected to a motor; the motor is electrically connected to the control board 7; when the waste liquid in the liquid storage chamber 31 reaches a certain amount, the waste liquid in the liquid storage chamber 31 flows into the liquid outlet chamber 34 by opening the double door 33; a liquid outlet chamber 34 is provided at the bottom of the main body 3, and the liquid outlet chamber 34 is located at the bottom of several liquid storage chambers 31; a second liquid outlet pipe 35 is provided at the bottom of the liquid outlet chamber 34, one end of the second liquid outlet pipe 35 passes through the main body 3 and is located outside the main body 3; the waste liquid in the liquid outlet chamber 34 flows out of the main body 3 through the second liquid outlet pipe 35 and flows into the waste liquid treatment base station 2.

[0042] The waste liquid treatment base station 2 is equipped with a groove 21 and a baffle 22, with the baffle 22 placed on one side of the groove 21. The bottom of the groove 21 is provided with a liquid inlet. When the waste liquid collection robot 1 moves to the waste liquid treatment base station 2, the probe 36 detects the distance to the baffle 22. When the set distance is reached, the waste liquid collection robot 1 stops moving, and the waste liquid in the waste liquid collection robot 1 enters the waste liquid treatment base station 2 through the liquid inlet. The waste liquid collection robot 1 is also charged. This saves working time and reduces pollution.

[0043] The disinfection device 6 includes several disinfection chambers 61, each corresponding to a liquid storage chamber 31. Each disinfection chamber 61 is placed on top of each liquid storage chamber 31. Several disinfection tablets are placed inside each disinfection chamber 61, and a first sensor 62 is provided at the bottom of each disinfection chamber 61. When the first sensor 62 at the bottom of the disinfection chamber 61 at the top of the liquid storage chamber 31 detects that there is no waste liquid in the liquid storage chamber 31, a set number of disinfection tablets are inserted into the liquid storage chamber 31. When waste liquid enters the liquid storage chamber 31, the disinfection tablets disinfect the waste liquid.
