Description

Technical Field

[0001] The present invention relates to the technical field of drainage equipment, and in particular to a cardiology nursing effusion drainage and extraction device. Background Art

[0002] Drainage and extraction of effusions (such as pericardial effusion and pleural effusion) in cardiology nursing is an important clinical procedure aimed at relieving symptoms, clarifying the diagnosis or treating the disease.

[0003] During the drainage of the effusion, the doctor will penetrate the tissue through the puncture needle to reach the lesion. At this time, the built-in drainage tube will be passed through the puncture needle to reach the lesion, and then the other end of the built-in drainage tube will be connected to a drainage pump or a suction tube to extract the effusion. During the drainage of the effusion, multiple long-term drainages are often required, and the built-in drainage tube needs to be in the body for a long time. At this time, the built-in drainage tube needs to be limited to ensure that the built-in drainage tube does not move in the body, and the wound needs to be disinfected regularly during daily maintenance to avoid infection. Furthermore, during drainage, in order to ensure that the effusion can be fully discharged, the built-in drainage tube needs to be moved at the lesion. When the built-in drainage tube applies too much pressure, it is very easy to cause damage to the tissue at the lesion, and heavy bleeding is prone to occur at the location where there are blood vessels. Therefore, the doctor needs to be very careful when finding the position, which makes the operation inconvenient. Based on this, a cardiology nursing effusion drainage and extraction device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the existing drainage, in order to ensure that the accumulated fluid can be fully discharged, the built-in drainage tube needs to be moved at the lesion site. When the built-in drainage tube is under too much pressure, it is very easy to cause damage to the tissue at the lesion site, and heavy bleeding is also prone to occur at the location where there are blood vessels. Therefore, the doctor needs to be very careful when finding the position, which makes the operation inconvenient. A cardiology nursing fluid drainage and extraction device is proposed. By clamping the split tube and the fastening pressure ring, the metal puncture tube is dynamically fixed by spring pressure to ensure the stable position of the internal and external drainage tubes, avoid the displacement or falling off of the tubes due to patient activities or external force, and organize the redundant tubes outside the body through the cooperation of the connector and the socket, reduce the risk of misoperation caused by the clutter of the tubes, and reduce the maintenance difficulty of nursing staff.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cardiology nursing effusion drainage and extraction device comprises a built-in drainage tube body connected to an extraction and drainage bag, wherein one end of the built-in drainage tube body is provided with a pipeline connector connected to the pipeline of the extraction and drainage bag;

[0007] The built-in drainage tube body is composed of a metal puncture tube and a protective puncture head arranged at one end of the metal puncture tube. A limiter is provided on the outside of the metal puncture tube to limit the movement of the metal puncture tube. A puncture port sealing cover is provided at the bottom of the limiter. An assembly seat for fixing the pipeline docking device is provided at one end of the puncture port sealing cover.

[0008] The protective thorn head includes a flow control end tube connected to the metal puncture pipe, the bottom of the flow control end tube is connected to a protective ring through a plurality of elastic docking pieces, and a protective ball end is movably arranged in the protective ring.

[0009] As a preferred solution, a plug-in connector is provided at the bottom of the pipeline docking device, and a socket adapted to the plug-in connector is provided on the assembly base, and the plug-in connector and the socket can be assembled and installed.

[0010] As a preferred embodiment, the limiter includes a connecting sleeve arranged on the puncture port sealing cover, a clamping splitting tube is arranged on the top of the connecting sleeve, a fastening pressure ring is slidingly arranged on the outer side wall of the connecting sleeve, and the fastening pressure ring is connected to the puncture port sealing cover through a resisting pressure spring arranged on the outer side wall of the connecting sleeve.

[0011] As a preferred solution, a funnel flow groove is provided at the bottom of the flow control end tube. When the elastic docking piece is in a folded state, the protective ball end is in the funnel flow groove, which can control the flow rate of the accumulated liquid.

[0012] As a preferred solution, the elastic butt joint piece is composed of hard thick metal at both ends and folded thin metal connecting the hard thick metal, and the two ends of the hard thick metal are respectively connected to the protective ring and the flow control end tube through the connecting thin metal.

[0013] As a preferred solution, the protective ball end is movably arranged in the protective ring and can achieve free rolling.

[0014] As a preferred solution, medical-grade skin patches are provided around the puncture port sealing cover.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention adjusts the folding state of the elastic docking piece by applying pressure, controls the degree of blockage of the funnel flow slot by the protective ball end, and realizes dynamic adjustment of the drainage speed (such as slow drainage to prevent re-expansion pulmonary edema), avoiding blood vessel rupture or damage to the lesion tissue due to excessive suction pressure. The protective ball end adopts a spherical design to reduce the risk of scratching the lesion tissue when the drainage tube moves. The elastic docking piece automatically folds and cushions when improper pressure is applied, avoiding tissue or blood vessel damage caused by excessive compression.

[0017] 2. The present invention dynamically fixes the metal puncture tube by clamping the split tube and the fastening pressure ring, using spring pressure to ensure the stable position of the internal and external drainage tubes, avoiding the displacement or falling off of the tubes due to patient activities or external force. By cooperating with the connector and the socket, the redundant tubes outside the body are sorted out, reducing the risk of misoperation caused by the clutter of the tubes, and reducing the maintenance difficulty for nursing staff.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0028] Example, see Figures 1 to 6 A device for draining and extracting effusion in cardiology nursing, comprising a built-in drainage tube body connected to an extraction and drainage bag assembly, a pipeline connector 1 connected to a pipeline of the extraction and drainage bag is provided at one end of the built-in drainage tube body, the pipeline connector 1 is a prior art, which can realize the effective connection between the built-in drainage tube body and the extraction and drainage tube with different diameters, which will not be described in detail here, a puncture port sealing cover 5 is provided at the bottom of the limiter 4, and a medical-grade skin patch 9 is provided around the puncture port sealing cover 5, which can avoid the wound from being exposed and causing infection by adhering to the skin of the wound with the medical-grade skin patch 9.

[0029] One end of the puncture port sealing cover 5 is provided with an assembly seat 6 for fixing the pipeline dock 1; a connector 7 is provided at the bottom of the pipeline dock 1, and a socket 8 adapted to the connector 7 is provided on the assembly seat 6, and the connector 7 and the socket 8 can be assembled and installed.

[0030] By using the cooperation between the connector 7 and the socket 8, the redundant metal puncture tube 2 outside the body can be sorted out, so that the metal puncture tube 2 can be sorted and fixed in position after the length of the metal puncture tube 2 inside the body is sufficient for drainage.

[0031] The built-in drainage tube body consists of a metal puncture tube 2 and a protective puncture head 3 arranged at one end of the metal puncture tube 2. A limiter 4 is provided on the outside of the metal puncture tube 2 to limit the movement of the metal puncture tube 2. Furthermore, the limiter 4 includes a connecting sleeve 41 arranged on the puncture port sealing cover 5, and a clamping splitting tube 42 is provided on the top of the connecting sleeve 41. A fastening pressure ring 43 is slidingly provided on the outer side wall of the connecting sleeve 41. The fastening pressure ring 43 is connected to the puncture port sealing cover 5 through a resisting pressure spring sleeved on the outer side wall of the connecting sleeve 41.

[0032] A further advantage of adopting the above method is that when the metal puncture tube 2 needs to be adjusted, it is only necessary to apply downward pressure to the fastening pressure ring 43 to move it downward, thereby disengaging the clamping split tube 42. At this time, the clamping split tube 42 will release the clamping force on the metal puncture tube 2. When the metal puncture tube 2 needs to be clamped, it is only necessary to release the pressure on the fastening pressure ring 43. Under the action of the resisting pressure spring, the fastening pressure ring 43 will squeeze the clamping split tube 42 to effectively clamp the metal puncture tube 2, thereby ensuring that the metal puncture tube 2 in the body will not move, and also avoiding the situation where the drainage tube outside the body falls off from the body due to pulling.

[0033] The protective thorn head 3 includes a flow control end tube 31 connected to the metal puncture pipe 2. The bottom of the flow control end tube 31 is connected to a protective ring 33 through multiple elastic docking pieces 32. The elastic docking piece 32 is composed of hard thick metal at both ends and folded thin metal connecting the hard thick metal. The two ends of the hard thick metal are respectively connected to the protective ring 33 and the flow control end tube 31 through connecting thin metal, which can enable the elastic docking piece 32 to achieve a folding effect. Its memory metal material can automatically reset after the pressure disappears.

[0034] A protective ball end 34 is movably provided in the protective ring 33. The protective ball end 34 is movably provided in the protective ring 33 and can roll freely. Such a structural design can ensure that when the built-in drainage tube body moves in the diseased tissue in the body, the spherical setting of its end can avoid damage to the tissue, and the spherical setting of the protective ball end 34 can also ensure that the tissue will not be scratched during the movement.

[0035] When the doctor applies improper pressure, the pressure will cause the elastic docking piece 32 to fold. When the folding occurs, the elastic release can be achieved, which can avoid damage to the diseased tissue. While protecting the patient, it is also more convenient for the doctor to operate.

[0036] Furthermore, a funnel flow groove 35 is provided at the bottom of the flow control end tube 31. When the elastic docking piece 32 is in the folded state, the protective ball end 34 is in the funnel flow groove 35, which can control the flow rate of the accumulated fluid.

[0037] During the drainage process, when slow drainage is required to protect the lesion, pressure can be applied to the built-in drainage tube body to fold the elastic docking piece 32. At this time, the protective ball end 34 will be close to the flow control end tube 31 and block the funnel flow slot 35. The greater the pressure, the more obvious the blocking effect on the funnel flow slot 35, so it can meet the effect of controlling the drainage flow.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
