Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a positioner for clinical intrarenal peritoneal dialysis. Background Art

[0002] Intrarenal peritoneal dialysis (PD) is a renal replacement therapy that uses the body's own peritoneum as a dialysis membrane. By infusing dialysate into the abdominal cavity, solute exchange between blood and dialysate is achieved to remove metabolic waste and excess fluid from the blood.

[0003] Peritoneal dialysis catheter drift refers to the situation where the peritoneal dialysis catheter is displaced in the abdominal cavity, resulting in poor drainage of the dialysis fluid. Peritoneal dialysis catheter drift can cause many inconveniences to patients, such as the inability of the dialysis fluid to flow smoothly into or out of the abdominal cavity, affecting the effect of dialysis and reducing the ability to remove waste and excess water from the body. Patients may feel abdominal discomfort or pain due to poor drainage of the dialysis fluid.

[0004] Peritoneal dialysis catheter blockage refers to the phenomenon that the inflow or outflow of dialysate is blocked due to various reasons during peritoneal dialysis. This situation may be caused by a variety of factors, including non-mechanical factors (such as blood clots, fibrin blockage) and mechanical factors (such as omentum, mesenteric wrapping, abdominal adhesions, catheter twisting, organ compression, etc.).

[0005] When the above problems occur, if conservative treatment is ineffective, surgical treatment may be required, otherwise it is difficult to intervene. In severe cases, laparoscopy-assisted adjustment or re-catheterization is required. In some cases, if the catheter blockage cannot be resolved, the patient may need to switch to hemodialysis or other renal replacement therapies.

[0006] There are some new intrarenal peritoneal dialysis positioners that hope to solve this problem. Patent publication number CN111658866B discloses a positioner for peritoneal dialysis catheterization in the nephrology department. The invention uses the cooperation between the positioning curved column and the extension frame. The fixed extension frame can ensure the reliability and stability of the column movement of the positioning curved column. Under the action of the driving gear and the driving gear ring, the positioning curved column can reliably cause the end face of the dialysis tube to produce a reliable angle deflection at the required position, so as to facilitate the reliable positioning of the dialysis tube to the position of the Douglas nest.

[0007] However, the device has certain limitations when used. On the one hand, the device can only control the bending direction of the dialysis tube in vitro, so it cannot accurately adjust the position of the tube opening of the dialysis tube; secondly, the device can only be used for auxiliary positioning during surgery, and if the patient has a drifting tube in daily life, it is not convenient to adjust and reset it. In addition, the device cannot solve the problem of tube blockage.

[0008] Therefore, there is a need for a positioner for intrarenal peritoneal dialysis that can assist in adjusting the position of the dialysis tube during surgery. When the dialysis tube drifts or deviates, the position of the head of the dialysis tube can be adjusted without the need for reoperation. In addition, the device can assist in clearing foreign matter from the tube opening when the dialysis tube opening is blocked. Summary of the invention

[0009] In order to solve the above technical problems, the present invention designs a positioner for clinical intrarenal peritoneal dialysis, wherein the device is provided by fixing an adjusting head at the front end of a conventional dialysis tube, and connecting the adjusting head and the control component through an adjusting trachea; when the dialysis tube drifts or shifts, the control component can be used to blow air into the adjusting trachea, and the control component can be set according to the direction in which the dialysis tube needs to move to change the direction of the gas outlet, and the reverse thrust of the gas can be used to enable the dialysis tube to move in the patient's body. In addition, if the tube is blocked, due to the structural design of the adjusting head, the foreign matter blocking the tube mouth can be blown away by blowing. In addition, in order to reduce the impact on the patient's daily life, the control component of the device can be removed when the dialysis tube does not need to be processed.

[0010] In order to achieve the above technical effects, the present invention discloses a positioner for clinical intrarenal peritoneal dialysis, comprising: an adjusting head, an adjusting air tube, and a control component; the adjusting head is fixedly installed at the dialysis tube orifice; the adjusting air tube is fixedly connected to the top of the adjusting head; the control component is detachably connected to the adjusting air tube;

[0011] The regulating head comprises: an air blowing pipe, a curved pipe, a one-way valve, a connecting rod, and an air distribution pipe;

[0012] The bottom of the insufflation tube is open, and four groups of circular holes in a circumferential array are arranged on the side of the insufflation tube, wherein each group of circular holes is divided into an air inlet and an air outlet, and the air inlet and the air outlet are coaxially aligned; the air outlet is also the liquid inlet of the dialysis tube;

[0013] The top of the gas distribution pipe is provided with four pipe holes, and the inside of the gas distribution pipe is respectively provided with gas distribution channels; the gas distribution channels penetrate to the bottom of the gas distribution pipe;

[0014] The one-way valve comprises a valve body, a ball, and a baffle. The inlet end of the valve body has a small diameter and the outlet end has a large diameter. The baffle is fixedly installed at the outlet end of the one-way valve. The ball is movably installed inside the valve body and the baffle.

[0015] The air inlet end of the one-way valve is fixedly connected to the bottom of the air distribution pipe, the air outlet end of the one-way valve is fixedly connected to one end of the bent pipe, and the other end of the bent pipe is fixedly connected to the air inlet hole of the blowing pipe;

[0016] Four independent inner pipes are arranged in the regulating air pipe, one end of the regulating air pipe is fixedly connected to the top of the air distribution pipe, and the four inner pipes of the regulating air pipe are respectively installed to align with the pipe holes of the air distribution pipe;

[0017] Furthermore, one end of the connecting rod is fixedly connected to the top of the air blowing pipe, and the other end of the connecting rod is fixedly connected to the bottom of the air distribution pipe;

[0018] Further, the control assembly includes: a connector, an adjustment disk, and an air blowing bag; an adjustment pipe is arranged inside the adjustment disk, and the adjustment disk is rotatably installed inside the connector; four connecting pipes corresponding to the adjustment endotracheal pipe are arranged inside the connector; the air blowing bag is fixedly connected to the adjustment disk;

[0019] Furthermore, the outside of the adjustment disk is provided with a positioning strip corresponding to the internal adjustment pipe; the outside of the connector is provided with four marking strips corresponding to the internal connection pipes;

[0020] Furthermore, the outside of the adjustment disk is provided with anti-slip stripes;

This avoids the complex and invasive operations that may be required by traditional solutions, reducing patient discomfort and treatment costs.

[0026] In addition, the control component of the positioner is designed to be detachable so that it can be removed when the dialysis tube does not need to be adjusted, reducing interference with the patient's daily life and improving the patient's quality of life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Example 1

[0040] The present invention discloses a positioner for clinical intrarenal peritoneal dialysis, referring to Figures 1 to 8 , including: an adjusting head 1, an adjusting air tube 2, and a control component 3; the adjusting head 1 is fixedly installed at the tube opening of the dialysis tube 5; the adjusting air tube 2 is fixedly connected to the top of the adjusting head 1; the control component 3 is detachably connected to the adjusting air tube 2;

[0041] The regulating head 1 includes an air blowing tube 101, an elbow 102, a one-way valve 103, a connecting rod 104 and an air distribution tube 105. The bottom of the air blowing tube 101 is designed with an opening, and the side is provided with four groups of circular holes in a circumferential array, each group of holes includes an air inlet 1011 and an air outlet 1012, and the axes of these two holes are aligned. In this way, when the gas flows inside the air blowing tube 101, it can flow from the air inlet 1011 to the air outlet 1012. The air outlet 1012 is also the liquid inlet of the dialysis tube 5, which means that if there is a foreign object blocking the liquid inlet, the regulating tube can also blow away the foreign object outside the liquid inlet.

[0042] There are four pipeline holes at the top of the gas distribution pipe 105, and the inside is respectively provided with gas distribution channels 1051, which penetrate to the bottom of the gas distribution pipe 105 to ensure that the gas can be evenly distributed to each pipeline hole, so as to achieve movement in four directions. The one-way valve 103 includes a valve body 1031, a ball 1032 and a baffle 1033, wherein the inlet end 1034 of the valve body 1031 has a smaller diameter, while the outlet end 1035 has a larger diameter, the baffle 1033 is fixedly installed at the outlet end 1035 of the one-way valve 103, and the ball 1032 is movably installed inside the valve body 1031 and the baffle 1033, such a structure can ensure that the gas can only flow in one direction, and ensure that the patient's body liquid will not flow out through the trachea.

[0043] The inlet end 1034 of the one-way valve 103 is fixedly connected to the bottom of the gas distribution pipe 105, while the outlet end 1035 is fixedly connected to one end of the elbow 102, and the other end of the elbow 102 is fixedly connected to the inlet hole 1011 of the air blowing pipe 101. This connection method ensures that the gas can pass from the control component 3 through the regulating air pipe 2, the gas distribution pipe 105, and the one-way valve 103, and finally reach the air blowing pipe 101, thereby realizing accurate control of the position of the dialysis tube 5.

[0044] Four independent inner pipes are arranged inside the regulating air pipe 2 , and these inner pipes enable the gas to be accurately guided to the various pipe holes of the gas distribution pipe 105 when flowing inside the regulating air pipe 2 .

[0045] Example 2

[0046] In this embodiment, the control assembly 3 is composed of three main parts: a connector 301, an adjustment disk 302, and an air blowing bag 303. The adjustment disk 302 is located inside the connector 301, and an adjustment pipe 3021 is arranged inside the adjustment disk 302, which allows the adjustment disk 302 to rotate freely inside the connector 301, thereby achieving precise control of the gas flow direction. This rotating installation design allows the adjustment disk 302 to adjust its position as needed to control the gas flow to adjust a specific pipe in the air pipe 2.

[0047] The connector 301 is internally designed with four connecting pipes 3011, which correspond one to one with the four independent internal pipes in the regulating air tube 2. This design ensures that the gas blown in from the control component 3 can be accurately guided to the specified part of the regulating air tube 2, thereby achieving accurate adjustment of the position of the dialysis tube 5, so that the operator can easily control the gas flow direction to control the dialysis tube 5 to move in different directions. The blowing bag 303 is fixedly connected to the regulating disk 302, and the operator blows gas into the regulating air tube 2 by squeezing the blowing bag 303. The operator can control the amount and speed of the blown gas.

[0048] In addition, the design of the control component 3 also takes into account the patient's comfort and treatment experience. By accurately controlling the position of the dialysis tube 5, the discomfort that may occur during the dialysis process can be reduced, and the patient's treatment satisfaction can be improved. At the same time, the detachable design of the control component 3 also makes it easy to remove the control component 3 when the dialysis tube 5 does not need to be adjusted, reducing interference with the patient's daily life.

[0049] Example 3

[0050] In this embodiment, a positioning strip 3022 is provided on the outside of the regulating disk 302, and the positioning strip 3022 precisely corresponds to the regulating pipe 3021 inside the regulating disk 302. Such a design allows the operator to intuitively understand the state and position of the internal regulating pipe 3021 by observing the external positioning strip 3022, thereby realizing precise control of the gas flow direction.

[0051] Four marking strips 3012 are arranged on the outside of the connector 301, and each marking strip 3012 corresponds to a connecting pipe 3011 inside the connector 301. These marking strips 3012 not only provide visual instructions, but also help the operator to identify and distinguish the function and flow direction of each connecting pipe 3011. This design enables the operator to quickly find the correct connecting pipe 3011 when adjusting the position of the dialysis tube 5, thereby improving the efficiency and accuracy of the operation. The provision of the marking strips 3012 also helps to reduce errors in operation and improve the safety of dialysis treatment.

[0052] In addition, anti-skid stripes are specially added to the outside of the adjustment disk 302. This detail design greatly improves the stability and safety of the operation. The anti-skid stripes are set to ensure that the medical staff can firmly hold the adjustment disk 302 and make precise adjustments during the operation even when the hands are sweaty or wet.

[0053] Example 4

[0054] In this embodiment, the connection between the regulating trachea 2 and the dialysis tube 5 is fixed by a bandage 4, which is a simple and effective fixing method. It can be adjusted according to the diameter of the dialysis tube 5 and the specific conditions of the patient's body to ensure that the position of the dialysis tube 5 in the patient's body is stable and prevent the dialysis tube 5 and the regulating trachea 2 from being entangled in the patient's body. In addition, the use of the bandage 4 also reduces the invasiveness to the patient's body. Compared with the traditional rigid connection method, the bandage 4 is fixed more gently, reducing the pressure on the patient's skin and tissue, thereby improving the patient's comfort.

[0055] Example 5

[0056] In this embodiment, during the dialysis treatment, any non-sterile gas entering the patient's abdominal cavity may cause microbial contamination and thus cause complications such as peritonitis. Therefore, ensuring the sterility of the gas is a key measure to prevent infection. In the field of medical devices, there are a variety of existing sterilization technologies that can ensure the sterility of the gas, such as supercritical carbon dioxide sterilization, nitrogen dioxide sterilization, accelerator-based radiation sterilization, vaporized hydrogen peroxide sterilization, etc. The gas needs to be sterilized before it can be used as the gas source supply of this device.

[0057] In addition, in actual use, when sterile gas is difficult to obtain or the sterility of the gas cannot be guaranteed, more easily available sterile liquids such as physiological saline can be used instead of the gas required by the device. The device uses the reaction force of the liquid flow as the power source for movement, and can still ensure a good effect of moving the pipeline and clearing foreign objects from the pipe mouth.

[0058] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only the specific implementation methods described.
