Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an adsorption component for preventing liquid seepage around a drainage tube and a drainage tube. Background Art

[0002] Clinically, the exudate around the drainage tube will contaminate and corrode the skin, causing discomfort to the patient and contaminating clothing and bedding. When there is a lot of exudate, it is necessary to constantly change the dressing, bedding and clothing, which increases the workload of medical staff. Some people have studied the use of ostomy bags to collect exudate, but after testing, it was found that the anti-leakage ointment located in the low-hanging parts of the body is easy to soak, which will cause leakage.

[0003] In order to effectively collect the exudate around the drainage tube, reduce or avoid leakage, improve the comfort of patients, and reduce the workload of medical staff, it is necessary to design an adsorption component for the exudate around the drainage tube that can prevent leakage and has good air permeability. In particular, how to optimize the collection of exudate in the low-hanging parts to ensure that there is no extravasation is the key issue to be solved. Summary of the invention

[0004] In view of the problems and shortcomings in the prior art, the present invention provides an adsorption component for preventing liquid seepage around a drainage tube and a drainage tube.

[0005] The technical solution of the present invention is as follows:

[0006] The utility model relates to an adsorption component for preventing liquid seepage around a drainage tube, comprising a bottom layer anti-seepage component and an upper layer anti-seepage component.

[0007] The bottom anti-seepage member comprises a first anti-seepage material and a connecting sleeve passing through the center of the first anti-seepage material and connected thereto, an opening is arranged on the tube wall of the connecting sleeve, the opening penetrates the connecting sleeve axially, a mounting opening is arranged on the first anti-seepage material portion on one side corresponding to the opening and penetrates the first anti-seepage material in the radial direction of the connecting sleeve, the mounting opening is aligned with the opening, and is used to sleeve the connecting sleeve onto the drainage tube from the side of the drainage tube. A first adhesive layer is arranged on the bottom surface of the first anti-seepage material.

[0008] The connecting sleeve is preferably made of a flexible elastic material, such as silicone or polyurethane, and the opening can expand under the action of an external force.

[0009] The upper layer of the anti-seepage member is arranged on the top surface of the bottom layer of the anti-seepage member, and one end is connected to the central part of the bottom layer of the anti-seepage member, and the connection method is arranged to enable the upper layer of the anti-seepage member to be transferred to any angle along the circumference of the connecting sleeve. The upper layer of the anti-seepage member has a second anti-seepage material, and the overlapping area of ​​the second anti-seepage material and the first anti-seepage material is less than half of the area of ​​the first anti-seepage material. When in use, the outer edge of the second anti-seepage material can extend to the outside of the first anti-seepage material to contact the human body, and a second adhesive layer is provided on the side in contact with the human body.

[0010] Preferably, the first adhesive layer and the second adhesive layer are provided with plastic protective paper outside. When in use, after tearing off the outer plastic protective paper, the bottom layer anti-seepage member and the upper layer anti-seepage member can be pasted on the operator's body.

[0011] The first barrier material and the second barrier material are at least partially a multi-layer absorbent material including a surface layer and an absorbent layer.

[0012] Further preferably, the first anti-seepage material and the second anti-seepage material include a surface layer, a guide layer, an absorption layer and an anti-leakage layer which are arranged in sequence from bottom to top.

[0013] More specifically, the surface layer is made of non-woven fabric, the guide layer is made of high-loft non-woven fabric and composite fiber, the absorption layer is made of wood pulp fiber and high-molecular water-absorbent resin, and the leak-proof layer is made of polyethylene film and breathable film.

[0014] In order to prevent the body fluids seeping out of the incision of the drainage tube from overflowing from the installation opening of the first impermeable material, sealing members can be provided on both sides of the installation opening. The sealing members can be Velcro, including a hook surface and a fleece surface fixedly connected to both sides of the installation opening, one side of which can be folded upward to open, or folded and covered on the other side to close the installation opening.

[0015] A rope fixing part can be provided on the wall of the connecting sleeve, and one end of the upper layer impermeable member is connected to the rope fixing part through an elastic rope, so as to prevent the upper layer impermeable member from being separated from the bottom layer impermeable member and being lost. A rope threading hole for connecting the elastic rope can be provided on the second impermeable material near one end of the connecting sleeve.

[0016] Preferably, the second impermeable material is connected to the top surface of the first impermeable material through Velcro. Specifically, the second impermeable material is detachably connected to the first connection part on the top surface of the first impermeable material through the third connection part at the bottom, the first connection part and the third connection part are respectively the hook side or the fleece side of the Velcro, the first connection part is arranged at a position close to the edge of the first impermeable material, and the position of the third connection part corresponds to the position of the first connection part.

[0017] The second anti-seepage material of the present invention is folded upward at least once and connected by docking buckles on the docking surfaces after folding. In the folded state, the outer edge of the second anti-seepage material no longer exceeds the outer edge of the first anti-seepage material or a part of the size can still extend to the outside of the first anti-seepage material.

[0018] Preferably, a guide rope groove is provided on the outer wall of the connecting sleeve, and the elastic rope can be wound more than half a circle in the guide rope groove. The upper layer anti-seepage member can also be connected to the bottom layer anti-seepage member by tying the elastic rope in the guide rope groove.

[0019] In order to prevent the central part of the first impermeable material from actively absorbing the body fluid of the surgical patient at the drainage port, the first impermeable material is designed to include a central part and a main body located outside the central part, wherein the adsorption capacity of the central part to the exudate is different from that of the main body. Preferably, the adsorption capacity of the central part to the exudate is weaker than that of the main body, so that the first impermeable material mainly absorbs the exudate overflowed around the drainage tube, and does not produce obvious active adsorption of the body fluid of the surgical patient.

[0020] The present invention also provides a drainage tube equipped with the above-mentioned adsorption component, which can be inserted into the connecting sleeve of the adsorption component, and has a plurality of drainage holes on the end and / or the side wall of the end extending into the body.

[0021] The beneficial effects of the present invention are:

[0022] The present invention absorbs the exudate around the drainage tube through the bottom layer impermeable member of the multi-layer absorbent material, thereby reducing the discomfort caused to the patient and the contamination of clothing and bedding. In addition, the upper layer impermeable member is connected to the top surface of the top layer impermeable member, and the connection method is set to enable the upper layer impermeable member to be transferred to any angle along the circumference of the connecting sleeve, so as to absorb the local exudate at the edge of the bottom layer impermeable member, effectively collect the exudate around the drainage tube, reduce or avoid leakage, and further improve the patient's comfort, especially for the collection of exudate in the low-hanging parts, which plays an important role in ensuring no extravasation.

[0023] The bottom layer impermeable member of the present invention is installed from the side of the drainage tube through the installation opening of the first impermeable material and the opening of the connecting sleeve, which facilitates the installation, fixing and replacement of the bottom layer impermeable member on the drainage tube.

DETAILED DESCRIPTION

[0037] The technical means adopted to achieve the predetermined inventive objectives of the present invention will be further described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] Example 1

[0039] See also Figure 1 , an adsorption component for preventing liquid seepage around a drainage tube 3, comprising a bottom layer anti-seepage component 1 and an upper layer anti-seepage component 2.

[0040] See also Figure 1-Figure 5 The bottom anti-seepage member 1 comprises a first anti-seepage material 11 and a connecting sleeve 12 passing through the center of the first anti-seepage material 11 and connected thereto. An opening 121 is provided on the wall of the connecting sleeve 12. The opening 121 penetrates the connecting sleeve 12 axially. A mounting opening 111 is provided on the first anti-seepage material 11 corresponding to the opening 121 and penetrates the first anti-seepage material 11 along the radial direction of the connecting sleeve 12. The mounting opening 111 is aligned with the opening 121 and is used to sleeve the connecting sleeve 12 onto the drainage tube 3 from the side thereof. A first adhesive layer 16 is provided on the bottom surface of the first anti-seepage material 11.

[0041] The connecting sleeve 12 is made of a flexible elastic material, such as silicone or polyurethane, and the opening 121 can expand under the action of an external force.

[0042] See also Figure 1 , Figure 2 , Figure 6 and Figure 7The upper layer impermeable member 2 is arranged on the top surface of the bottom layer impermeable member 1, and one end is connected to the central part of the bottom layer impermeable member 1. The connection method is set to enable the upper layer impermeable member 2 to be transferred to any angle along the circumference of the connecting sleeve 12. The upper layer impermeable member 2 has a second impermeable material 21, and the overlapping area of ​​the second impermeable material 21 and the first impermeable material 11 is less than half of the area of ​​the first impermeable material 11. Preferably, the overlapping area of ​​the second impermeable material 21 and the first impermeable material 11 is less than one-third of the area of ​​the first impermeable material 11. More preferably, the overlapping area of ​​the second impermeable material 21 and the first impermeable material 11 is one-quarter to one-sixth of the area of ​​the first impermeable material 11. When in use, the outer edge of the second impermeable material 21 can extend to the outside of the first impermeable material 11 to contact the human body, and a second adhesive layer 25 is provided on the side in contact with the human body.

[0043] The first adhesive layer 16 and the second adhesive layer 25 are provided with plastic protective paper outside. When in use, the outer plastic protective paper is torn off, and the bottom impermeable member 1 and the upper impermeable member 2 can be pasted on the body of the operator. The adhesive layer of the first impermeable material 11 and the second impermeable material 21 is arranged at a position near the outer edge of the bottom surface.

[0044] The first impermeable material 11 and the second impermeable material 21 are at least partially made of a multi-layer adsorbent material including a surface layer a and an absorbent layer c. Specifically, the first impermeable material 11 is made of a multi-layer adsorbent material as a whole, and the second impermeable material 21 can be made of a multi-layer adsorbent material as a whole or partially. For example, the part of the second impermeable material 21 that overlaps with the first impermeable material 11 in the unfolded state can be made of no adsorbent material or a simpler adsorbent material (such as a single-layer adsorbent material or a thinner adsorbent material) can be used.

[0045] See also Figure 1 and Fig.10 The shape of the first anti-seepage material 11 can be rectangular, circular or other clinically suitable shapes.

[0046] See also Figure 1 and Figure 8After the drainage tube 3 is inserted into the surgical patient, it can be fixed by special-shaped 3M glue first, and then the adsorption component of the present invention is taken, and the installation port 111 of the first waterproof material 11 is first separated by hand and passed through the drainage tube 3 from the side to reach the connecting sleeve 12, and then the opening 121 of the connecting sleeve 12 is separated outwardly so that the connecting sleeve 12 can be sleeved on the drainage tube 3, and finally the plastic protective paper at the bottom of the first waterproof material 11 is uncovered, so that the first waterproof material 11 is pasted on the upper body of the surgical patient. The first waterproof material 11 absorbs body fluids such as blood or tissue fluid overflowing from the incision of the drainage tube 3. In the initial state, the second waterproof material 21 can be connected to the top surface of the first waterproof material 11 by Velcro, and the connection position avoids the installation port 111 and the opening 121, so the second waterproof material 21 does not affect the installation of the bottom waterproof component 1. After fixing the first barrier material 11, the second barrier material 21 may not be unfolded first, and when body fluids overflow from the periphery of the first barrier material 11, the second barrier material 21 may be unfolded and transferred to the periphery of the first barrier material 11 where exudate overflows, and the portion thereof extending from the first barrier material 11 (the portion folded in the initial state) is covered on the periphery of the first barrier material 11 to absorb the exudate flowing out from the local edge of the first barrier material 11, thereby playing a role in supplementing and absorbing the exudate, especially collecting the exudate from the drooping parts, which plays an important role in ensuring that there is no extravasation. Of course, after fixing the first barrier material 11, the second barrier material 21 may be directly unfolded and the extended portion may be transferred to the periphery of the first barrier material 11 where exudate is prone to occur, such as the drooping parts, and the specific operation method is flexible and can be selected as needed.

[0047] See also Fig.11 In order to improve the absorption capacity, the first anti-seepage material 11 and the second anti-seepage material 21 preferably include a surface layer a, a guide layer b, an absorption layer c and a leakproof layer d arranged in order from bottom to top. More preferably, the surface layer a is made of non-woven fabric, the guide layer b is made of high-loft non-woven fabric and composite fiber, the absorption layer c is made of wood pulp fiber and high molecular water-absorbing resin, and the leakproof layer d is made of polyethylene film and breathable film.

[0048] See also Figure 3 In order to prevent the body fluids seeping out of the incision of the drainage tube 3 from overflowing from the installation opening 111 of the first impermeable material 11, sealing members 13 are provided on both sides of the installation opening 111. The sealing member 13 can be a Velcro, including a hook surface and a fleece surface fixedly connected to both sides of the installation opening 111, one side of which can be folded upward to open, or folded and covered on the other side, so that the installation opening 111 is closed.

[0049] See also Figure 5In this embodiment, a rope fixing portion 122 is provided on the wall of the connecting sleeve 12, and one end of the upper layer impermeable member 2 is connected to the rope fixing portion 122 through an elastic rope, so that the upper layer impermeable member 2 can be flexibly placed and fixed around the bottom layer impermeable member 1. A rope threading hole 23 for connecting the elastic rope is provided near one end of the connecting sleeve 12 on the second impermeable material 21, and the other end of the elastic rope is connected to the second impermeable member through the rope threading hole 23. Removable connecting buckles can be provided at both ends of the specific elastic rope for easy disassembly.

[0050] See also Figure 1 , Figure 6 and Figure 7 , the second anti-seepage material 21 is connected to the top surface of the first anti-seepage material 11 through Velcro. Specifically, the second anti-seepage material 21 is detachably connected to the first connection part on the top surface of the first anti-seepage material 11 through the third connection part at the bottom, the first connection part and the third connection part are respectively the hook surface or the fleece surface of the Velcro, the first connection part is arranged at a position close to the edge of the first anti-seepage material 11, and the position of the third connection part corresponds to the position of the first connection part.

[0051] See also Figure 7 In order to strengthen the fixation, a second connection part can be further provided near the center of the top surface of the first impermeable material 11, and a fourth connection part connected thereto can be provided at a corresponding position of the second impermeable material 21, and the two are also the hook surface or the fleece surface of the Velcro. In a specific embodiment, the second connection part is a surface of an annular Velcro, and the fourth connection part is a curved Velcro fleece surface corresponding to the second connection part.

[0052] The second barrier material 21 is folded upward at least once, and after being folded, it is connected by the docking buckle 24 located on the docking surface. In the folded state, the outer edge of the second barrier material 21 no longer exceeds the outer edge of the first barrier material 11, or a portion of the size can still extend to the outside of the first barrier material 11. The docking interface can use a detachable connector such as Velcro or a hidden buckle. The second barrier material 21 is folded upward at least once. For example, if the second barrier material 21 is folded once, Figure 7 and Figure 8 As shown, the second anti-seepage material 21 can be folded upward once in the middle, and a folding line or folding groove 22 for folding can be further provided in the middle of the second anti-seepage material 21.

[0053] See also Figure 5 A rope guide groove 123 may be further provided on the outer wall of the connecting sleeve 12, and the elastic rope may be wound more than half a circle in the rope guide groove 123. The upper layer impermeable member 2 may also be connected to the bottom layer impermeable member 1 by tying the elastic rope in the rope guide groove 123.

[0054] Example 2

[0055] See also Fig. 9In order to prevent the center of the first impermeable material 11 from producing an active adsorption effect on the body fluid of the surgical patient at the drainage port, the first impermeable material 11 is designed to include a center and a main body located outside the center, wherein the adsorption capacity of the center for exudate is different from that of the main body. Preferably, the adsorption capacity of the center for exudate is weaker than that of the main body, which can be achieved in the following ways: making the thickness of the adsorption material of the center smaller than that of the adsorption material of the main body, or making one or several layers of the material of the center different from that of the main body, or adding a layer of material with barrier properties to exudate on the side of the center in contact with the human body. In this way, the first impermeable material 11 mainly adsorbs the exudate overflowing around the drainage tube, and will not produce a significant active adsorption effect on the body fluid of the surgical patient.

[0056] The other features of this embodiment are the same as those of Embodiment 1 and will not be described in detail.
