Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a suction cup type negative pressure drainage tube fixing and shaping device. Background Art

[0002] Negative pressure wound therapy, a novel approach that has emerged in the past decade to accelerate wound healing, has been widely used to treat a range of difficult-to-treat wounds, including acute, chronic, and infected wounds, accelerating the closure of infected cavities and the healing of infected wound surfaces. Histological examinations have confirmed that wounds treated with negative pressure sealing and drainage experience a rapid decline in lymphocyte infiltration, early onset of collagen synthesis during the proliferative phase, and enhanced contractile fiber synthesis during the repair phase. This therapy significantly increases wound blood flow, promotes the removal of necrotic tissue and bacteria, accelerates the growth of granulation tissue and the proliferation of repair cells, and promotes capillary angiogenesis.

[0003] However, when the existing drainage tube is actually used, the plastic joint of the drainage tube and the joint of the negative pressure device may be loosely connected due to human dragging, causing the joint of the drainage tube to fall off from the negative pressure drainage device and form a detached tube, which will cause the drainage fluid to flow out and the tube to be temporarily connected to the outside world, causing the possibility of infection. In addition, during the movement of the drainage tube, one end of the drainage tube located at the negative pressure drainage device may be bent, causing the drainage tube to be blocked. Utility Model Content

[0004] The problem to be solved by the present invention is to overcome the problem in the above-mentioned prior art that the drainage tube may be dragged by humans, and the plastic joint of the drainage tube may be loosely connected to the joint of the negative pressure device, thereby causing the joint of the drainage tube to fall off from the negative pressure drainage device and form a detached tube, which may cause the drainage fluid to flow out and the pipeline to be temporarily connected to the outside world, causing the possibility of infection. In addition, during the movement of the drainage tube, one end of the drainage tube located at the negative pressure drainage device may be bent, thereby causing the drainage tube to be blocked.

[0005] A suction cup type negative pressure drainage tube fixing and shaping device is proposed, comprising a drainage tube for drainage, a supporting spiral protective sleeve for supporting the drainage tube, a fixed shell for connecting the supporting spiral protective sleeve, and a suction cup for adsorbing the negative pressure drainer. The drainage tube is connected to the center position of the fixed shell, multiple groups of supporting spiral protective sleeves are vertically connected to the fixed shell, and the supporting spiral protective sleeves are arranged around the drainage tube with the midpoint of the drainage tube as the center of the circle and are all connected to the drainage tube. There are multiple groups of suction cups and they are all connected to the bottom of the fixed shell.

[0006] In the technical solution of the present invention, the drainage tube is supported by a supporting spiral protective sleeve with plastic properties, so the drainage tube at the fixed shell will not bend, thereby avoiding blockage of the drainage tube, and the first spiral protective sleeve and the second spiral protective sleeve are fixedly connected to the drainage tube through bonding points, and the first spiral protective sleeve and the second spiral protective sleeve are bonded to the fixed shell, so the drainage tube will not fall out from the inside of the fixed shell, and the fixed shell is adsorbed on the negative pressure drainage device through a suction cup, so the drainage tube can be prevented from falling off from the negative pressure drainage device, thereby avoiding tube detachment, which is used to solve the problem mentioned in the technical background that the drainage tube will be dragged by humans, and the plastic joint of the drainage tube and the joint of the negative pressure device are not firmly connected, thereby causing the joint of the drainage tube to fall off from the negative pressure drainage device and form a tube detachment, which will cause the drainage fluid to flow out and the pipeline to be temporarily connected to the outside world, causing the possibility of infection, and during the movement of the drainage tube, the end of the drainage tube located at the negative pressure drainage device will be bent, thereby causing blockage of the drainage tube.

[0007] According to the preferred technical solution of the present invention, the supporting spiral protective sleeve is made of plastic with plasticity. The plastic with plasticity has a certain hardness. Therefore, after the supporting spiral protective sleeve is wrapped around the drainage tube, the supporting spiral protective sleeve will only support the drainage tube to prevent it from bending.

[0008] In the preferred technical solution of the present invention, the supporting protective sleeve includes a first spiral protective sleeve and a second spiral protective sleeve, the second spiral protective sleeve is threadedly connected to the first spiral protective sleeve, and the bonding point is connected to the second spiral protective sleeve, so when the bonding point needs to be replaced, the second spiral protective sleeve can be directly replaced.

[0009] In a preferred embodiment of the technical solution of the present invention, the top end of the second spiral protective sleeve is connected with an adhesive point. After the adhesive point is adsorbed on the drainage tube, the drainage tube and the fixed shell can be connected together by using the supporting spiral protective sleeve.

[0010] In a preferred embodiment of the technical solution of the present invention, the bonding points are convex points and traceless glue, and the traceless glue is bonded to the convex points. The traceless glue can be used repeatedly without leaving any marks.

[0011] The preferred technical solution of the utility model is that a notch is opened on the fixed shell, and the drainage tube can directly enter the interior of the fixed shell through the notch, avoiding the previous plug-in connection method, thereby avoiding contamination of the drainage tube joint.

[0012] Preferably, the fixing shell is made of a transparent material, and the fixing shell is made of transparent plastic, so the doctor does not need to remove the fixing shell when necessary, and can directly observe the connection between the drainage tube and the negative pressure drainer through the fixing shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model can, after the drainage tube is placed inside the fixed shell, wrap the supporting spiral protective sleeve around and adsorb it on the drainage tube. The supporting spiral protective sleeve with plastic properties can support the drainage tube, thereby preventing the drainage tube from bending at one end of the negative pressure drain device, causing clogging of the drainage tube. Moreover, after the fixed shell is adsorbed on the negative pressure drain device through the suction cup and the supporting spiral protective sleeve is wrapped around and adsorbed on the drainage tube, the position of the drainage tube between the top end of the fixed shell and the negative pressure drain device cannot be displaced. Therefore, when the drainage tube is moved, the connector of the drainage tube will not fall off the negative pressure drain device, thereby avoiding the drainage tube from being over-hosted.

[0020] The following is a combination of the appended examples of the present invention Figure 1-4 , the technical solutions in the embodiments of the present utility model are described in detail.

[0021] like Figure 1-4 As shown, a suction cup type negative pressure drainage tube fixing and shaping device includes a drainage tube 1 for drainage, a supporting spiral protective sleeve 2 for supporting the drainage tube 1, a fixed shell 3 for connecting the supporting spiral protective sleeve 2 and a suction cup 4 for adsorbing the negative pressure drainer, the fixed shell 3 is an inwardly concave fixed shell 3, and the fixed shell 3 is made of a transparent material (such as plastic).

[0022] like Figure 1-4As shown, when necessary, the doctor does not need to remove the fixed shell 3 from the negative pressure drain device, and can directly observe the connection between the drainage tube 1 inside the fixed shell 3 and the negative pressure drain device through the fixed shell 3. The fixed shell 3 is an inwardly concave fixed shell 3, so its surface is three-dimensional, which makes it easier for the doctor to directly remove the fixed shell 3 from the negative pressure drain device when needed. The drainage tube 1 is set at the center position of the fixed shell 3.

[0023] like Figure 1-4 As shown, the axis of the drainage tube 1 is perpendicular to the top surface of the fixed shell 3, a through hole is provided at the center of the fixed shell 3, and a slot is provided on one side of the fixed shell 3, so that the drainage tube 1 can be directly placed into the interior of the central through hole of the fixed shell 3 through the slot, and there are multiple groups of supporting spiral protective sleeves 2, which are all vertically connected to the top of the fixed shell 3, and the supporting spiral protective sleeves 2 are arranged around the drainage tube 1 with the midpoint of the drainage tube 1 as the center of the circle.

[0024] like Figure 1-4 As shown, the supporting spiral protective sleeve 2 is made of plastic with plastic properties, and the bottom end of the supporting spiral protective sleeve 2 is bonded to the top of the fixed shell 3. Therefore, after the drainage tube 1 is placed into the fixed shell 3, the supporting spiral protective sleeve 2 can be rotated with the midpoint of the drainage tube 1 as the center of the circle and close to the outer wall of the drainage tube 1, and it is ensured that each group of supporting spiral protective sleeves 2 is in contact with the drainage tube 1, and the supporting spiral protective sleeve 2 itself has plasticity.

[0025] like Figure 1-4 As shown, after the supporting spiral protective sleeve 2 is wrapped around the outer wall of the supporting spiral protective sleeve 2, the supporting spiral protective sleeve 2 will support the drainage tube 1 and shape the drainage tube 1 to prevent the drainage tube 1 from bending at the position of the fixed shell 3 and causing blockage of the drainage tube 1. The supporting spiral protective sleeve 2 includes a first spiral protective sleeve 21 and a second spiral protective sleeve 22. One end of the first spiral protective sleeve 21 is bonded to the fixed shell 3, and the other end of the first spiral protective sleeve 21 is threaded.

[0026] like Figure 1-4 As shown, the second spiral protective sleeve 22 is connected to the first spiral protective sleeve 21 through the thread at the top of the first spiral protective sleeve 21. Therefore, when the spiral protective sleeve 2 is rotated and supported, it is only necessary to rotate the second spiral protective sleeve 22, and the first spiral protective sleeve 21 will rotate along with the second spiral protective sleeve 22. One end of the second spiral protective sleeve 22 is connected to the top of the first spiral protective sleeve 21, and the other end of the second spiral protective sleeve 22 is connected to the bonding point 5.

[0027] like Figure 1-4As shown, the bonding point 5 used includes a protrusion 51 and a traceless glue 52. The protrusion 51 is melt-bonded to the top of the second spiral protective sleeve 22, and the traceless glue 52 is bonded to the protrusion 51. Therefore, after the supporting spiral protective sleeve 2 is rotated and wrapped around the outer wall of the drainage tube 1, the traceless glue 52 on the protrusion 51 can be bonded to the outer wall of the drainage tube 1. After the drainage tube 1 is bonded with the traceless glue 52, the drainage tube 1 and the fixed shell 3 can be connected together through the traceless glue 52 and the supporting spiral protective sleeve 2.

[0028] like Figure 1-4 As shown, the drainage tube 1 can be prevented from falling off from the inside of the fixed shell 3. After the supporting spiral protective sleeve 2 is rotated and wrapped around the drainage tube 1, the distance between the protrusion 51 at the top of the supporting spiral protective sleeve 2 and the top of the fixed shell 3 is about 5 cm. The label that meets the management requirements of the drainage tube 1 is fixed at a standard of 5 cm at the outlet of the drainage tube 1.

[0029] like Figure 1-4 As shown, each set of first spiral protective sleeves 21 and second spiral protective sleeves 22 are bonded with friction strips on the surface in contact with the drainage tube 1. Therefore, after the first spiral protective sleeves 21 and the second spiral protective sleeves 22 are wrapped around the drainage tube 1, the friction strips will directly contact the outer wall of the drainage tube 1 to increase the friction between the drainage tube 1 and the first spiral protective sleeves 21 and the second spiral protective sleeves 22.

[0030] like Figure 1-4 As shown, the friction strip will help the traceless glue 52 to absorb the drainage tube 1 to prevent the drainage tube 1 from falling off the fixed shell 3. There are multiple groups of suction cups 4 and they are all arranged under the fixed shell 3. The suction cups 4 are evenly rotated and arranged at the bottom end of the fixed shell 3 with the center of the drainage tube 1 as the center of the circle. Each group of suction cups 4 is connected to the fixed shell 3 by screws.

[0031] like Figure 1-4 As shown, the fixed shell 3 can be fixed on the negative pressure drain device by suction through the suction cup 4, so after the drainage tube 1 is plugged into the negative pressure drain device, and the supporting spiral protective sleeve 2 is wrapped around the drainage tube 1, and the fixed shell 3 is adsorbed on the negative pressure drain device by the suction cup 4, the relative position of the drainage tube 1 between the top end of the fixed shell 3 and the negative pressure drain device will not be displaced, so no matter how the drainage tube 1 outside the supporting spiral protective sleeve 2 moves, the drainage tube 1 will not fall off from the negative pressure drain device to form a detached tube.

[0032] The movement process of this embodiment: after the drainage tube 1 is placed into the center position of the fixed shell through the notch of the fixed shell 3, the drainage tube 1 can be inserted into the negative pressure drainer, and then the suction cup 4 at the lower end of the fixed shell 3 is adsorbed on the outer wall of the negative pressure drainer, and then the spiral protective sleeve 2 is rotated forward until the first spiral protective sleeve 21 and the second spiral protective sleeve 22 are tightly attached to the outer wall of the drainage tube 1, the protrusion 51 can be pressed and the traceless glue 52 can be adhered to the outer wall of the drainage tube 1, so that the negative pressure drainer, the fixed shell 3 and the drainage tube 1 are fixedly connected together.

[0033] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
