Description

Technical Field

[0001] This utility model relates to the field of nursing technology, specifically to a nursing drainage device. Background Technology

[0002] The existing device connects one end of the drainage tube to the human body. Fluid produced in the body flows into the reservoir in the drainage bottle. Before use, a minimum and maximum monitoring value must be set for the water level sensor. When the water level sensor detects that the drainage fluid in the reservoir has reached the set minimum value, the control module activates a buzzer to alert the patient that the reservoir is about to fill. If the nursing staff fails to process the drainage fluid in the reservoir in time for various reasons, when the drainage fluid in the reservoir reaches the set maximum value, the control module opens the solenoid valve, and the drainage fluid in the reservoir flows into a backup reservoir through the guide tube. At this time, a certain amount of drainage fluid can accumulate in the backup reservoir, waiting for the nursing staff to process it. The backup reservoir can prevent the drainage fluid from overflowing and causing backflow, thus preventing infection in the patient.

[0003] In the aforementioned device, the drainage catheter guides the fluid produced in the body to an external container through gravity flow. However, if the fluid concentration is too high during the drainage process, the flow rate will slow down. These highly concentrated fluids will stay in the catheter for too long, causing deposits or clots to accumulate and eventually block the drainage catheter. Therefore, a nursing drainage device is needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a nursing drainage device that solves the technical problem mentioned in the background art: when the liquid concentration is too high and the flow rate slows down, it can lead to the accumulation of sediment or clumps in the pipe, thereby causing pipe blockage.

Each of the two suction tubes is provided with a flow-promoting component. The flow-promoting component includes several spacer rings arranged horizontally at equal intervals inside the suction tubes. A flow-controlling ring is fixed to the outer wall of each of the several spacer rings. A connecting ring is fixed between the several spacer rings. Several grooves are circumferentially and equidistantly formed on the outer wall of the connecting ring. A flow-promoting element is fixed inside each of the several grooves. An air supply component is provided inside the suction bag to drive the flow-promoting element to switch between convex and flat positions.

[0006] Preferably, the air supply assembly includes an air storage cavity formed on the inner wall of the suction bladder, a conduction cavity connected to the inside of the air storage cavity is formed on the inner wall of the suction and discharge tube, and a plurality of flow guide holes penetrating its left and right sides are formed circumferentially on the inner wall of the flow control ring, a plurality of flow storage cavities are formed between the plurality of spacer rings, and the plurality of flow storage cavities are connected to each other through the plurality of flow guide holes.

[0007] Preferably, the gas storage chamber and the conduction chamber are internally connected and filled with expanding gas, and the expanding gas is connected to the storage chamber through a guide hole.

[0008] Preferably, the outer wall of the flow-promoting element is coated with a smooth layer, and the smooth layer is formed by at least one multiple coating.

[0009] Preferably, the material of the flow-promoting element includes, but is not limited to, rubber, and the material of the smoothing layer includes, but is not limited to, polyethylene.

[0010] Preferably, the two suction and discharge tubes are provided with two check valves inside, and the two check valves are arranged in opposite directions with respect to the suction bladder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model can achieve passive suction and discharge of liquid, thereby effectively performing care and drainage, and can effectively prevent liquid backflow and blockage of suction and discharge tubes, especially when handling high-concentration liquids, ensuring normal operation of the device and avoiding blockage problems.

[0013] 2. The suction and discharge tube of this utility model, in conjunction with the repeated action of the flow-promoting element's continuous convex arc shape change during the liquid suction and discharge process, can greatly reduce the adhesion of high-concentration liquids, making the liquid flow more smoothly in the suction and discharge tube, especially the fluidity of high-concentration liquids, reducing adhesion.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] In existing devices, the drainage catheter guides fluid generated within the body to an external container via gravity flow. However, if the fluid concentration becomes too high during drainage, the flow rate slows down. This high-concentration fluid remains in the catheter for an extended period, leading to the accumulation of deposits or clots, ultimately causing blockage. Please refer to [link to relevant documentation]. Figures 1-4 To reduce pipe blockage caused by excessively high fluid concentration, ensure smooth drainage, and aid patient recovery, this embodiment provides a nursing drainage device. It includes two suction tubes 11 fixedly connected to the outside of a suction bag 1. Each suction tube 11 contains two check valves 3, oriented opposite to each other with respect to the suction bag 1. One end of one suction tube 11 is connected to the patient, and the other end is connected to a collection bottle. During operation, medical personnel first manually squeeze the suction bag 1 to expel the gas, causing the check valve 3 in the suction tube 11 connected to the collection bottle to open. At this time, the gas in the suction tube 11 connected to the collection bottle is expelled, while the check valve 3 in the suction tube 11 connected to the patient closes. As the medical personnel release the suction bag 1, a negative pressure is created inside, drawing fluid from the patient into the suction bag 1. At this point, the check valve 3 in the suction tube 11 connected to the collection bottle is closed, while the check valve 3 in the suction tube 11 connected to the patient is open, ensuring that the liquid only flows into the aspiration bag 1 and preventing backflow. When the medical staff squeezes the aspiration bag 1 again, the liquid inside the aspiration bag 1 is expelled from the body through the suction tube 11 connected to the collection bottle. The entire process is repeated continuously to achieve the suction and expulsion of the liquid, thereby effectively providing care and draining fluid.

[0023] Example 2

[0024] Based on Example 1, squeezing and releasing the suction bag 1 can improve the efficiency of liquid suction and discharge. However, high-concentration liquids usually have high viscosity and poor flowability. This makes it easy for the liquid to rub against the inner wall of the suction and discharge tube 11 when flowing through it, causing the liquid to adhere to the tube wall. To further reduce this adhesion and improve the flowability of high-concentration liquids, refer to... Figures 3-4 By setting a flow-promoting component 2 inside the two suction pipes 11, the flow-promoting component 2 includes several spacer rings 21 arranged laterally at equal intervals inside the suction pipes 11. The outer walls of the spacer rings 21 are all fixed with flow control rings 22, and the spacer rings 21 are all fixed with connecting rings 23. The outer walls of the connecting rings 23 are circumferentially and equidistantly provided with several grooves. The interiors of the grooves are all fixed with flow-promoting elements 24. The material of the flow-promoting elements 24 includes, but is not limited to, rubber material. The outer walls of the flow-promoting elements 24 are coated with a smooth layer 241, and the smooth layer 241 is formed by at least 1-3 multiple coatings. This means that the thickness and uniformity of the coating will be better, which helps to enhance the smoothness of the surface. The multiple coating process can ensure that the smooth layer 241 has a more durable effect and can provide a more uniform coating coverage. The smooth layer 241 is made of, but is not limited to, polyethylene, which reduces the adhesion of liquid to the surface of the flow promoter 24, thereby improving the fluidity of the liquid and making it easier for the liquid to flow on the smooth surface, avoiding liquid stagnation or poor flow caused by the roughness or strong adhesion of the surface of the flow promoter 24. The suction bag 1 is internally provided with an air supply assembly 25 for driving the flow promoter 24 to switch between convex and flat states. The air supply assembly 25 includes an air storage chamber 251 formed in the inner wall of the suction bag 1, a conduction chamber 252 connected to the interior of the air storage chamber 251 on the inner wall of the suction / exhaust tube 11, and a plurality of flow guide holes 253 equidistantly formed on the inner wall of the flow control ring 22, penetrating its left and right sides. A plurality of flow storage chambers 254 are formed between the plurality of spacer rings 21, and the plurality of flow storage chambers 254 are connected to each other through the plurality of flow guide holes 253. The interior of the air storage chamber 251 and the conduction chamber 252 is filled with expanding gas, which is connected to the flow storage chamber 254 through the flow guide holes 253. When medical staff manually squeeze the aspiration bag 1, the expanding gas in the gas storage chamber 251 is forced out, enters the conduction chamber 252, and pushes the expanding gas in the guide hole 253 to be simultaneously transferred to the storage chamber 254. After the gas in the storage chamber 254 is filled, it is transferred to the next storage chamber 254 in sequence through several guide holes 253. The sufficient gas in each storage chamber 254 will push the flow-promoting element 24, causing the flow-promoting element 24 to bulge into a convex arc shape, which helps to improve the fluidity of the liquid, especially the fluidity of high-concentration liquids, and reduce adhesion. When the medical staff releases the aspiration bag 1, the gas in the gas storage chamber 251 is recovered, and the flow-promoting element 24 returns to its original state, forming a repeatable cycle. Through the repeated action of the continuous convex arc shape change, the adhesion of high-concentration liquids can be greatly reduced, making the flow of liquid in the suction tube 11 smoother.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
