Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically a medical drainage kit. Background Technology

[0002] Drainage is a surgical treatment method that includes external drainage and internal drainage. External drainage involves using drainage tubes to transfer pus, blood, and other fluids accumulated between body tissues, outside body cavities, and inside internal organs to the outside of the body. Examples of external drainage include thoracic drainage, abdominal drainage, biliary drainage, nephrostomy, cystostomy, and urine drainage.

[0003] During drainage, a surgical incision or puncture site needs to be created in the skin to allow the drainage tube to be inserted. However, due to factors such as the body's immune response and tissue fluid, exudate may occur at the surgical incision site. If the exudate remains at the surgical incision site for a long time, it can easily cause excessive moisture at the surgical incision site, leading to redness, swelling, pain, and other infection symptoms. At the same time, long-term local placement of the tube can easily form sinus tracts, making the tube prone to loosening and increasing the possibility of local tube dislodgement or displacement. Utility Model Content

[0004] To reduce humidity at the surgical incision site and prevent redness, swelling, pain, or even infection, while also reducing the possibility of tube dislodgement or displacement, this application provides a medical drainage kit.

[0005] A medical drainage kit includes: a drainage tube; a fixation member having an adhesive surface and a fixing hole for the drainage tube to pass through the fixation member, and a working cavity arranged around the axis of the fixing hole, the fixing hole including a first segment communicating with the adhesive surface, the inner diameter of the first segment being larger than the outer diameter of the drainage tube, a first partition being provided between the fixing hole and the working cavity, the first partition being arranged around the axis of the fixing hole and having multiple communicating holes communicating with the first segment and the working cavity, the fixation member also having a first channel for the working cavity to communicate with the outside; and a drainage strip disposed in the working cavity and detachably connected to the working cavity, the drainage strip being able to enter the outside through the first channel.

[0006] In one embodiment of this application, a plurality of connecting holes are arranged in an axis array around a fixed hole.

[0007] In one embodiment of this application, the fastener includes an upper housing and a lower housing with an adhesive surface. The upper housing and the lower housing are detachably connected, and the working cavity can be opened when the upper housing and the lower housing are separated.

[0008] In one embodiment of this application, the fastener is provided with an outwardly extending connecting portion, and the connecting portion is provided with a first channel; both the upper housing and the lower housing are provided with outwardly extending sub-connecting portions, and when the upper housing and the lower housing are connected, the two sub-connecting portions form a connecting portion and form the first channel.

[0009] In one embodiment of this application, the medical drainage kit further includes a reservoir bag, which has an inlet. The inner diameter of the inlet is not less than the outer diameter of the connector. The connector can be inserted into the inlet and is detachably connected to the inlet.

[0010] In one embodiment of this application, the side wall of the drainage tube is provided with a first snap-fit ​​structure, and the inner wall of the fixing hole is provided with a second snap-fit ​​structure, and the first snap-fit ​​structure and the second snap-fit ​​structure are snapped together.

[0011] In one embodiment of this application, the first snap-fit ​​structure is a snap-fit ​​groove, and the second snap-fit ​​structure is a snap-fit ​​protrusion; the fixing hole also includes a second hole segment, and the first hole segment and the second hole segment are arranged sequentially along the axis of the fixing hole and away from the application surface; the second hole segment is provided with a snap-fit ​​protrusion, which is located on the inner wall of the second hole segment around the axis of the fixing hole; the outer wall of the drainage tube is provided with a snap-fit ​​groove around its axis, and when the drainage tube passes through the fixing hole, the snap-fit ​​protrusion and the snap-fit ​​groove can snap together.

[0012] In one embodiment of this application, the first snap-fit ​​structure is a snap-fit ​​sleeve, the outer wall of which is provided with a snap-fit ​​portion that can snap-fit ​​with the second snap-fit ​​structure; the inner wall of the snap-fit ​​sleeve is provided with an elastic collar, and the snap-fit ​​sleeve can be fitted onto the drainage tube through the elastic collar.

[0013] In one embodiment of this application, the fastener includes an adhesive portion having an adhesive surface, the adhesive portion being flexible and bendable; the adhesive surface having an adhesive layer, and when the adhesive portion is in its natural state, the adhesive layer forming an adhesive plane, and the axis of the fastening hole being perpendicular to the adhesive plane.

[0014] In one embodiment of this application, the medical drainage kit further includes a reservoir bag, the inlet of which is connected to the first channel, and the drainage strip in the working chamber extends to the bottom of the reservoir bag through the first channel and the inlet.

[0015] The beneficial effects of this application are at least as follows:

[0016] 1. The fixation element in this application is fixed to the skin surface. When the fixation hole is fitted onto the drainage tube, due to the gap between the fixation hole and the drainage tube, the exudate from the surgical incision can enter the first hole segment and enter the working chamber through the connecting hole, where it is absorbed by the drainage strip. The fixation element isolates the drainage strip from the surgical incision, preventing the drainage strip that has absorbed the exudate from directly contacting the surgical incision, thereby reducing the humidity at the surgical incision and maintaining the cleanliness of the surgical incision.

[0017] 2. The working chamber can be opened by using a fastener to connect the detachable upper and lower shells, allowing for the replacement of the drainage strip and maintaining the cleanliness of the surgical incision. Attached Figure Description

[0032] Please see Figures 1 to 6 Learn more about this application.

[0033] See Figure 1 A medical drainage kit, comprising a drainage tube, a fixation element, and a drainage strip.

[0034] The fixation member 201 is provided with an application surface 202 and a fixing hole 203 through which the drainage tube 101 passes, and a working cavity 207 arranged around the axis of the fixing hole 203. In one embodiment of this application, the fixation member 201 includes an adhesion part with an application surface 202. The application surface 202 is provided with an adhesive layer. When the adhesion part is in its natural state, the adhesive layer forms an adhesive plane. The axis of the fixing hole 203 is perpendicular to the adhesive plane. Furthermore, the adhesion part is flexible and can be bent. The adhesion part can bend to a certain extent to conform to the physiological curve of the patient's abdomen or chest cavity, so that the application surface 202 can be firmly adhered to the patient's skin surface.

[0035] See Figures 1 to 3 The working chamber 207 is equipped with a drainage strip 402. The fixing hole 203 includes a first hole segment 204 communicating with the dressing surface 202. The inner diameter of the first hole segment 204 is larger than the outer diameter of the drainage tube 101. There is a gap between the first hole segment 204 and the drainage tube 101. When the dressing surface 202 is applied near the surgical incision, the surgical incision is within the coverage area of ​​the fixing hole 203. A first partition 208 is provided between the fixing hole 203 and the working chamber 207. The first partition 208 is arranged around the axis of the fixing hole 203 and has multiple connecting holes 206 connecting the first hole segment 204 and the working chamber 207. Exudate from the surgical incision can enter the gap between the first hole segment 204 and the drainage tube 101, and then enter the working chamber 207 through the connecting holes 206. Thus, the exudate is absorbed by the drainage strip 402 in the working chamber 207. See [reference needed]. Figure 3 The fixing member 201 is also provided with a first channel 209 for the working chamber 207 to communicate with the outside. The drainage strip 402 can enter the outside through the first channel 209 and extend out of the first channel 209. See Figure 2Ultimately, the exudate can enter the outside through the first channel 209, thereby reducing the exudate at the surgical incision and ensuring that the humidity at the surgical incision is within a suitable range. The drainage strip 402 is detachably connected to the working chamber 207, so that when the humidity of the drainage strip 402 is too high, a dry drainage strip 402 can be used to replace the wet drainage strip 402 in time. The first partition 208 can also isolate the wet drainage strip 402 from the skin, ensuring that the humidity at the surgical incision is within a suitable range and avoiding symptoms such as redness and swelling at the surgical incision.

[0036] See Figure 1 , Figure 3 In one embodiment of this application, a plurality of connecting holes 206 are arranged in an array around the axis of the fixing hole 203, so that exudate appearing at different locations can enter the working chamber 207 through different connecting holes 206, thereby ensuring that the humidity at the surgical incision is within a suitable range.

[0037] For easy replacement of the drainage strip 402 inside the working chamber 207, see [link / reference]. Figure 1 , Figure 4 In one embodiment of this application, the fixing member 201 includes an upper housing 301 and a lower housing 302 with an application surface 202. The upper housing 301 and the lower housing 302 are detachably connected. The upper housing 301 and the lower housing 302 can be connected by snap-fit, overlap, stud fixation or other means, so that the upper housing 301 and the lower housing 302 can be separated from each other, realizing the detachable connection between the upper housing 301 and the lower housing 302. When the upper housing 301 and the lower housing 302 are separated, the working chamber 207 can be opened, so that the drainage strip 402 can be replaced in time, ensuring that the humidity at the surgical incision is within a suitable range.

[0038] See Figure 1 , Figure 2 , Figure 5 , Figure 6 Furthermore, in one embodiment of this application, the fixing member 201 is provided with an outwardly extending connecting portion, and the connecting portion is provided with a first channel 209; both the upper housing 301 and the lower housing 302 are provided with outwardly extending sub-connecting portions 303. When the upper housing 301 and the lower housing 302 are connected, the two sub-connecting portions 303 form a connecting portion, and the two sub-connecting portions 303 form the channel wall of the first channel 209, thus forming the first channel 209. When the upper housing 301 and the lower housing 302 are separated, the first channel 209 can be fully opened, making it convenient to remove the drainage strip 402 that has entered the first channel 209, thus avoiding the situation where the fixing member 201 jams the drainage strip 402.

[0039] In one embodiment of this application, the medical drainage kit further includes a reservoir bag 401. The reservoir bag 401 has a liquid inlet, the inner diameter of which is not less than the outer diameter of the connecting part. The connecting part can be inserted into the liquid inlet and is detachably connected to the liquid inlet. The liquid inlet can restrict the separation of the two sub-connecting parts 303 and restrict the separation of the upper housing 301 and the lower housing 302, preventing the upper housing 301 and the lower housing 302 from separating due to patient movement, collisions, or other issues. Preferably, the inner diameter of the liquid inlet is equal to the outer diameter of the connecting part, thereby ensuring that the liquid inlet restricts the upper housing 301 and the lower housing 302 from separating radially along the first channel 209. Furthermore, the liquid inlet is threadedly connected to the connecting part, realizing a detachable connection between the liquid inlet and the connecting part. At the same time, the liquid inlet restricts the axial movement of the upper housing 301 and the lower housing 302 along the first channel 209 through the thread. Of course, there are other ways to achieve a detachable connection between the liquid inlet and the connecting part, such as having a flexible liquid inlet that can be bound to the groove of the connecting part by components such as cable ties, which will not be elaborated here.

[0040] In one embodiment of this application, the medical drainage kit further includes a reservoir bag 401. The inlet of the reservoir bag 401 is connected to the first channel 209. The drainage strip 402 in the working chamber 207 extends to the bottom of the reservoir bag 401 through the first channel 209 and the inlet. The position of the reservoir bag 401 can be lower than the position of the surgical incision. Under the action of gravity, the exudate flows into the reservoir bag 401. The extension of the drainage strip 402 to the bottom of the reservoir bag 401 increases the extension distance of the drainage strip 402 in the depth direction of the reservoir bag 401 and the coverage area of ​​the drainage strip 402 in the reservoir bag 401, thereby accelerating the entry of exudate into the reservoir bag 401.

[0041] See Figure 5 In one embodiment of this application, the medical drainage kit further includes a reservoir bag 401. The inlet of the reservoir bag 401 is connected to the first channel 209. The wall of the reservoir bag 401 is transparent and has a capacity scale, which makes it convenient for medical staff to understand the amount of seepage at the surgical incision and adjust the treatment plan in a timely manner.

[0042] See Figure 3 In one embodiment of this application, the side wall of the drainage tube 101 is provided with a first snap-fit ​​structure 102, and the inner wall of the fixing hole 203 is provided with a second snap-fit ​​structure 210. The first snap-fit ​​structure 102 and the second snap-fit ​​structure 210 are snapped together, so that the fixing member 201 can fix the drainage tube 101 and prevent the drainage tube 101 from falling out. At the same time, it reduces the friction of the drainage tube 101 on the surgical incision and reduces the possibility of the surgical incision being damaged by the drainage tube 101.

[0043] See Figure 3In one embodiment of this application, the first snap-fit ​​structure 102 is a snap-fit ​​groove, and the second snap-fit ​​structure 210 is a snap-fit ​​protrusion; the fixing hole 203 includes a first hole segment 204 and a second hole segment 205, arranged sequentially along the axis of the fixing hole 203 and away from the application surface 202; the second hole segment 205 is provided with a snap-fit ​​protrusion, which is located on the inner wall of the second hole segment 205 around the axis of the fixing hole 203; the outer wall of the drainage tube 101 is provided with a snap-fit ​​groove around its axis, and when the drainage tube 101 passes through the fixing hole 203, the snap-fit ​​protrusion and the snap-fit ​​groove can snap together, the fixing member 201 fixes the drainage tube 101, and the snap-fit ​​protrusion and the snap-fit ​​groove are tightly snapped together to prevent seepage from entering the outside through the first hole segment 204 and the second hole segment 205.

[0044] Those skilled in the art to which this application pertains will understand that the first snap-fit ​​structure 102 may also be a snap-fit ​​protrusion, and the second snap-fit ​​structure 210 may be a snap-fit ​​groove. The first snap-fit ​​structure 102 may snap-fit ​​with the second snap-fit ​​structure 210, which will not be described in detail here.

[0045] The first snap-fit ​​structure 102 and the second snap-fit ​​structure 210 can also be implemented in other ways. In one embodiment of this application, the first snap-fit ​​structure 102 is a snap-fit ​​sleeve, and the outer wall of the snap-fit ​​sleeve is provided with a snap-fit ​​part that can snap with the second snap-fit ​​structure, such as a snap-fit ​​part being a slot, and the second snap-fit ​​structure 210 being a snap-fit ​​strip that can snap with the slot; or, the snap-fit ​​part is a snap-fit ​​strip, and the second snap-fit ​​structure 210 is a slot that can snap with the snap-fit ​​strip; the inner wall of the snap-fit ​​sleeve is provided with an elastic collar, and the snap-fit ​​sleeve can be fitted onto the drainage tube 101 through the elastic collar. The elastic ring can be made of materials such as rubber or silicone, and it can be stretched and contracted. Thus, the elastic ring can be fitted onto drainage tubes 101 of different diameters, and the elastic ring can move along the drainage tube 101. After reaching the designated position, the elastic ring is located in a fixed position on the drainage tube 101 due to friction. The snap-fit ​​sleeve is connected to the fixing member 201 by snap-fit, thereby fixing the drainage tube 101. By changing the position of the elastic ring on the drainage tube 101, the length of the drainage tube 101 that can be inserted into the patient's body can be changed to meet different usage needs.

[0046] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
