Description

Technical Field

[0001] The invention relates to the field of abdominal drainage tubes, and in particular to an abdominal drainage tube device. Background Art

[0002] Drainage of abdominal and pleural effusion is a common treatment method in clinical practice, which is used to relieve the pressure of abdominal or pleural effusion caused by various reasons and improve the patient's symptoms. In this process, the correct placement and stable fixation of the drainage tube are crucial. However, there are some problems with traditional drainage tubes in practical applications, mainly reflected in: the drainage position at the head of the drainage tube cannot be accurately located, and improper drainage position may lead to poor drainage, which in turn affects the treatment effect.

[0003] In order to overcome the above problems, some innovative solutions have emerged in recent years. Chinese patent CN105641759 B proposes a magnetic abdominal drainage tube device, which is characterized in that a magnetic inner core is arranged in the drainage tube and a magnetic controller is connected to the outside. The position of the magnetic inner core in the body can be remotely adjusted by the magnetic controller, thereby changing the position of the head end of the drainage tube to achieve precise drainage. In addition, the head end of the magnetic inner core is also equipped with an air bag, which can be inflated and deflated by an external vacuum device to meet different drainage needs.

[0004] Although this magnetic abdominal drainage tube device provides a flexible method for adjusting the position of the drainage tube in theory, in practical applications, the interaction between the magnetic controller outside the body and the magnetic core inside the body has certain limitations. Specifically:

[0005] The attraction of the magnetic controller outside the body to the magnetic inner core causes the tip of the inner core to move only in the direction of the controller, and cannot be controlled in the opposite direction, which limits the flexibility of adjusting the position of the drainage tube tip. For example, when the drainage tube tip needs to be adjusted to a position away from the magnetic controller, due to the attraction, the magnetic inner core tip is difficult to move in the desired direction, affecting the drainage effect and the accuracy of the operation.

[0006] The internal structure of the human body is complex, and the magnetic core may be hindered by surrounding tissues when moving in the body, affecting its ability to accurately reach the target location. Summary of the invention

[0007] The main purpose of the present invention is to provide an abdominal drainage tube device to solve the problem that the drainage position of the drainage tube head end cannot be accurately positioned, and improper drainage position may lead to poor drainage, thereby affecting the treatment effect.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: an abdominal drainage tube device, an adjusting hose is sleeved inside the drainage tube, an airbag is provided at the opening position of one end of the adjusting hose, the airbag is connected to the inflation valve at the end of the adjusting hose through the inflation tube inside the adjusting hose, a closed fixed disk is provided at the other end of the adjusting hose, at least four inner tubes are provided on the inner wall of the adjusting hose, adjustment wires are provided inside the four inner tubes, a ball head rod is provided at the end of the fixing disk, an adjustment handle is connected to the end of the ball head rod, one end of the adjusting wire is fixedly connected to the end of the adjusting hose, and the other end passes through the fixing disk and is connected to the adjustment handle.

[0009] In a preferred embodiment, the airbag is arranged at the end of the regulating hose and the airbag partly extends out of the end of the drainage tube.

[0010] In the preferred embodiment, a concave annular groove is provided in the middle of the airbag, and a limiting shrink ring with a shrinking structure is provided at the end of the drainage tube. After the airbag is inflated, the annular groove is stuck on the limiting shrink ring.

[0011] In a preferred embodiment, the adjustment handle is a cross structure, and the plates extending from the adjustment handle are respectively connected to the adjustment wires.

[0012] In a preferred embodiment, a ball head seat is provided on the adjustment handle, and the end of the ball head rod is connected to the ball head seat.

[0013] In the preferred embodiment, a spring is sleeved on the ball head rod, and two ends of the spring abut between the fixed plate and the adjusting handle.

[0014] In a preferred embodiment, a limit head is provided at the end of the adjustment line, and the limit head abuts against the countersunk hole at the end of the inner tube to limit the position.

[0015] In the preferred embodiment, a valve core is provided inside the inflation valve, and the airbag can be inflated and deflated by pressing the valve core.

[0016] The present invention provides an abdominal drainage tube device, which enables doctors to more effectively control the position of the drainage tube by introducing an adjustable hose system, thereby ensuring that the fluid is drained from the correct position, avoiding the occurrence of secondary surgery due to poor drainage, alleviating the pain of patients, and improving the recovery effect. Through the built-in adjustment hose and airbag system, doctors can adjust the position of the drainage tube as needed to achieve the best drainage effect. The design of the airbag helps to keep the drainage tube in the proper position to prevent displacement. The easy-to-operate handle and adjustment line are designed, so that doctors can easily adjust the direction and angle of the drainage tube manually without relying on other external devices.

DETAILED DESCRIPTION

[0025] Example 1

[0026] like Figures 1 to 6 As shown, an abdominal drainage tube device is provided, wherein an adjusting hose 3 is sleeved inside the drainage tube 1, an air bag 2 is provided at an opening position at one end of the adjusting hose 3, the air bag 2 is connected with an inflation valve 7 at the end of the adjusting hose 3 through an inflation tube 6 inside the adjusting hose 3, a closed fixing disk 4 is provided at the other end of the adjusting hose 3, at least four inner tubes 301 are provided on the inner wall of the adjusting hose 3, adjusting wires 5 are provided inside the four inner tubes 301, a ball head rod 10 is provided at the end of the fixing disk 4, an adjusting handle 8 is connected to the end of the ball head rod 10, one end of the adjusting wire 5 is fixedly connected to the end of the adjusting hose 3, and the other end passes through the fixing disk 4 and is connected to the adjusting handle 8.

[0027] The airbag 2 is first in a deflated state, at which time its volume is small, making it easy to insert into the end of the drainage tube 1 .

[0028] The regulating hose 3 with the airbag 2 is inserted into the end of the drainage tube 1, and connected to the inflation valve 7 through the inflation device to inflate the airbag 2. As the airbag expands, its annular groove 201 is stuck on the limiting shrink ring 101 at the end of the drainage tube 1 to form a stable fixed point.

[0029] Under B-ultrasound monitoring, the doctor can observe the position of the end of the drainage tube 1 in real time to ensure that it moves along the predetermined path.

[0030] By manually operating the adjustment handle 8, the bending degree and direction of the adjustment hose 3 can be precisely controlled. When the thumb presses one end of the adjustment handle 8, the adjustment line 5 at that end is loosened, while the adjustment line at the other end begins to tighten, driving the end of the adjustment hose 3 to bend, thereby guiding the drainage tube 1 to move forward and turn until the ideal drainage position is reached.

[0031] When the drainage tube 1 reaches the predetermined position, the inflation valve 7 is used to deflate the air again, so that the airbag 2 shrinks and releases the fixed relationship between the airbag 2 and the limiting shrink ring 101.

[0032] At this point, the entire adjustment hose 3 can be safely withdrawn, leaving the accurately positioned drainage tube 1 in the body to continue to perform its function.

[0033] By adjusting the handle 8 and the adjustment wire 5 , the doctor can accurately control the advancing direction and bending angle of the drainage tube 1 to ensure that it reaches the target area accurately.

[0034] The design of the device takes into account the doctor's operational convenience. The complex positioning process can be completed through simple manual operation, reducing the operation time and difficulty.

[0035] Adjust the appropriate hardness of hose 3:

[0036] Provide sufficient support force: The drainage tube 1 is softer than the adjustment hose 3, and the adjustment hose 3 needs to have a certain rigidity so that it can transmit force during external manual operation to achieve precise control of the position of the drainage tube 1. This includes adjusting the bending shape of the adjustment hose 3 through the adjustment handle 8, thereby changing the direction of the drainage tube.

[0037] Enhanced operating feel: Appropriate hardness can also provide doctors with better tactile feedback during operation, making it easier to sense the specific position and state of the adjustment hose 3 in the body, thereby improving the accuracy and efficiency of the operation.

[0038] The softness of the drainage tube 1 is lower than that of the adjustment hose 3, which not only ensures the safety and comfort of the drainage tube in the body, but also ensures the stability and controllability of the adjustment hose during operation. This differentiated softness and hardness design reflects the dual consideration of patient safety and surgical effect.

[0039] In a preferred embodiment, the airbag 2 is disposed at the end of the regulating hose 3 and the airbag 2 partially extends out of the end of the drainage tube 1. Figure 1-2 As shown, the use of the airbag 2 not only helps to fix the position of the drainage tube 1, but also reduces the damage to the surrounding tissue when the adjustment hose 3 is removed.

[0040] In the preferred embodiment, a concave annular groove 201 is provided in the middle of the airbag 2, and a limiting shrink ring 101 with a shrinking structure is provided at the end of the drainage tube 1. After the airbag 2 is inflated, the annular groove 201 is stuck on the limiting shrink ring 101.

[0041] When the airbag 2 is not inflated, its volume is small and can easily pass through the port of the drainage tube 1. Once the airbag begins to inflate, it will gradually expand. The annular groove 201 in the middle of the airbag 2 is designed so that as the volume of the airbag 2 increases, the annular groove 201 will also expand accordingly until it is finally stuck on the limiting shrink ring 101 at the end of the drainage tube. The limiting shrink ring 101 is a special shrinking structure, and its diameter is slightly smaller than the diameter of the drainage tube body, forming a "step". This step just matches the annular groove 201 after the airbag 2 is inflated, thereby forming a mechanical lock to prevent the airbag 2 from separating from the drainage tube 1 when moving in the body.

[0042] In the preferred embodiment, the adjustment handle 8 is a cross structure, and the plates extending from the adjustment handle 8 are respectively connected to the adjustment wires 5. The cross structure handle design allows the user to apply force from four different directions, and the plates in each direction are respectively connected to the adjustment wires 5. This means that the doctor can independently control the bending degree of the adjustment hose 3 in different directions by simply pressing or pulling different parts of the handle, thereby accurately adjusting the direction of the drainage tube 1.

[0043] The cross-structured handle provides clear operation instructions, and each plate corresponds to a specific adjustment line 5. In this way, the doctor can adjust the slight position change of the drainage tube 1 by directly pressing or releasing a specific plate according to the B-ultrasound image feedback, and the operation process is more intuitive and controllable.

[0044] Through the multi-directional control of the cross-structure adjustment handle 8, the doctor can adjust the position of the drainage tube 1 more carefully to ensure that it reaches the predetermined drainage position accurately and reduce the risk of complications caused by position deviation.

[0045] In the preferred embodiment, a ball head seat 801 is provided on the adjustment handle 8, and the end of the ball head rod 10 is connected to the ball head seat 801. A spring 9 is sleeved on the ball head rod 10, and the two ends of the spring 9 abut between the fixed plate 4 and the adjustment handle 8. The combination of the ball head seat 801 and the ball head rod 10 is similar to the structure of a joint, allowing the adjustment handle 8 to rotate freely in multiple directions.

[0046] When the adjusting handle 8 is pushed to a certain angle, when the handle is released, the elastic force of the spring 9 will cause the adjusting handle 8 to automatically return to the initial position. This feature is particularly important for surgical operations that require frequent adjustment of the handle angle, and it simplifies the operating steps.

[0047] The connection design between the ball head seat 801 and the ball head rod 10, with the assistance of the spring 9, allows the doctor to adjust the handle angle without restriction when operating the adjustment handle 8, meeting the needs of different surgical postures and increasing the freedom and comfort of operation.

[0048] In the preferred embodiment, a limit head 501 is provided at the end of the adjusting wire 5, and the limit head 501 is limited by abutting against the countersunk hole at the end of the inner tube 301. This facilitates the installation of the adjusting wire 5 and also limits the position of the end of the adjusting wire 5.

[0049] In the preferred embodiment, a valve core is provided inside the inflation valve 7, and pressing the valve core can inflate and deflate the airbag 2. When the doctor needs to inflate the airbag 2, the pressure applied by the inflation device can open the valve core to allow gas to flow into the airbag; and when deflation is required, pressing the valve core can also overcome the resistance of the spring to release the gas inside the airbag.

[0050] When no inflation or deflation operation is performed, the valve core automatically closes due to the elastic force of the internal spring to prevent gas leakage and ensure the stability and safety of the airbag during use.

[0051] Similar to inflating a tire, medical personnel can intuitively understand and operate the valve core in the inflation valve without the need for special training, which reduces the difficulty of operation and improves surgical efficiency.

[0052] Example 2

[0053] Further illustrate with reference to Example 1, Figure 1-6 The structure shown in the figure is used as follows: the airbag 2 is in a deflated state, the regulating hose 3 with the airbag 2 is inserted into the end of the drainage tube 1, and the inflation device is used to connect the inflation valve 7, and the airbag 2 is inflated so that the annular groove 201 of the airbag 2 is stuck in the limiting shrink ring 101 at the end of the drainage tube 1;

[0054] The drainage tube 1 is implanted in the body, and the position of the end of the drainage tube 1 is monitored by B-ultrasound. The thumbs of both hands are pressed on the position of the adjustment handle 8, and the index and middle fingers of both hands are pressed on the inner side of the fixing plate 4;

[0055] When the thumbs of both hands press one end of the cross plate of the adjustment handle 8, the adjustment line at the pressing position is relaxed, and the plate at the other end begins to pull the corresponding adjustment line inside the adjustment hose 3. The adjustment line at the pulling position pulls the end of the adjustment hose 3 to start bending, and the drainage tube 1 is adjusted to bend and change its position, and the airbag 2 turns to guide the drainage tube 1 forward;

[0056] According to B-ultrasound monitoring, the position of the drainage tube 1 is adjusted by repeatedly controlling the adjustment handle 8, so that the tip of the drainage tube 1 reaches the drainage position;

[0057] After reaching the drainage position, the valve core inside the inflation valve 7 is pressed, the airbag 2 discharges gas and shrinks, the annular groove 201 of the airbag 2 is disconnected from the limiting shrink ring 101 at the end of the drainage tube 1, the entire adjustment hose 3 is pulled out, and the implantation of the drainage tube 1 is completed.

[0058] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
