Description

Technical Field

[0001] The present application relates to the technical field of anorectal care equipment, and more specifically, to an internally supported anti-dislocation anal canal drainage device. Background Art

[0002] An anal drainage tube is a slightly thicker tube inserted into the anus and connected to the outside world for clinical drainage. It is primarily used to drain stool from the intestines or relieve pressure. This is particularly important after colorectal surgery, where a rectal drainage tube is needed to drain loose stools and prevent and reduce serious complications.

[0003] After the existing anal drainage tube is inserted into the patient's anus, it is fixed by using an inflatable balloon to expand inside the anus. However, the inflatable balloon of the anal drainage tube is easily deformed due to squeezing and easily slips out of the anal canal. It often needs to be repeatedly placed, which increases the workload of medical staff or patients' families and makes it inconvenient to use.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0005] The purpose of the present application is to provide an internally supported anti-slip anal canal drainage device, which solves the problem in the prior art that the inflatable air bag is easily deformed by squeezing and easily slips out of the anal canal, requiring repeated placement and causing inconvenience in use.

[0006] To achieve the above objectives, the technical solution adopted in this application is:

[0007] The present application provides an internally supported anti-dislocation anal canal drainage device, comprising:

[0008] a drainage tube having a distal end inserted into the anus and a proximal end located outside the patient's body;

[0009] An air bag is arranged at the distal end of the drainage main tube;

[0010] A plurality of support members surround the drainage main pipe, and one end of each support member is movably connected to the drainage main pipe, and the other end forms a support foot;

[0011] The support member is connected to the air bag, and the expansion of the air bag causes the support legs to be away from the drainage main pipe and to open, so as to squeeze the inner wall of the anus and limit the drainage main pipe.

[0012] Optionally, an inflation channel is provided in the drainage main pipe, the inflation channel is connected to the airbag, and an inflation connector is provided at the proximal end of the drainage main pipe, the inflation connector is connected to the inflation channel;

[0013] The airbag is inflated through the inflation channel to form an expanded state. In the expanded state, the airbag includes: an expansion support portion connected to the bottom of the support member;

[0014] The expansion filling portion is filled between adjacent support members.

[0015] Optionally, a hinged seat is provided on the outer wall of the drainage main pipe;

[0016] The support member comprises a support bar, one end of the support bar is hinged on the hinge seat, and the end of the support bar away from the hinge seat forms a support foot.

[0017] Optionally, the supporting foot includes an outer protrusion, which is located on a side of the supporting bar away from the drainage main pipe and is arranged obliquely to the extension direction of the supporting bar.

[0018] Optionally, a flexible adhesive layer is provided on the supporting foot.

[0019] Optionally, an inner groove is provided on the outer wall of the drainage main pipe, and when the airbag is in a contracted state, the support member is accommodated in the inner groove.

[0020] Optionally, the bottom of the inner groove is connected to the outer wall of the airbag via a first adhesive layer;

[0026] The beneficial effect of the internal support anti-slip anal drainage device provided by the present application is at least that: after the distal end of the drainage main pipe is inserted into the anus, the airbag is inflated and gradually expands. During the expansion process, not only does the airbag itself expand and contact the inside of the anus, but the expansion of the airbag causes the supporting feet to move away from the drainage main pipe and open, thereby squeezing the inner wall of the anus to limit the drainage main pipe, so that multiple support members are stretched around the drainage main pipe, so that the drainage main pipe can be stuck in the anus, thereby avoiding the problem of the distal end of the drainage main pipe being squeezed and easily slipping out of the anus.

[0039] like Figure 1 、 Figure 2 、 Figure 6As shown, this embodiment proposes an internal support anti-dislocation anal canal drainage device, which mainly includes: a drainage main pipe 100, an airbag 200 and a plurality of support members 300. The drainage main pipe 100 has a distal end inserted into the anus 10 and a proximal end located outside the patient's body. In the specific structure, the wall thickness of the distal end of the drainage main pipe 100 is relatively large, so it is not easy to deform under pressure at the distal end, so that it can withstand the squeezing of the muscles at the anus 10 without being easily deformed and sealed, thereby smoothly realizing the drainage function inside the anus 10. The airbag 200 is arranged at the distal end of the drainage main pipe 100. The airbag 200 can be inflated and expanded from the outside of the drainage main pipe 100. The inflated airbag 200 is located inside the anus 10 to stretch the inner wall of the anus 10, playing a certain limiting and fixing role. Multiple support members 300 surround the drainage main tube 100, with one end of each support member 300 movably connected to the drainage main tube 100 and the other end forming a support leg 320. Specifically, the support members 300 are in a contracted state when the airbag 200 is not inflated. In this contracted state, the support members 300 extend approximately along the axial direction of the drainage main tube 100 by a predetermined length. In this contracted state, the support members 300 adhere to the drainage main tube 100, facilitating insertion of the drainage main tube 100 into the anus 10. The support members 300 are also connected to the airbag 200. Once inside the anus 10, the inflated airbag 200 causes the support legs 320 to expand away from the drainage main tube 100, squeezing the inner wall of the anus 10 and retaining the drainage main tube 100 in place. This not only provides support through the inflated airbag 200 abutting against the inner wall of the anus 10, but also the expanded support members 300 position the airbag 200 and abut against the inner wall of the anus 10, providing support. In this way, the drainage main pipe 100 is stably stuck in the anus 10 by the combined action of the airbag 200 and the support member 300. During use, the internal support anti-dropout anal drainage device can be stuck on the inner wall of the anus 10 and fixed in place by squeezing the muscles of the anus 10. When the device contracts, it can be removed from the anus 10 by simply deflation. Figure 1 、 Figure 7 As shown, it can also be stuck at the junction of the anus 10 and the rectum 20. Then, when the support member 300 contracts, negative pressure needs to be provided, which can also solve the technical problem.

[0040] The present embodiment is an internally supported anti-dislocation anal drainage device. After the distal end of the drainage main pipe 100 is inserted into the anus 10, the airbag 200 is inflated to expand and gradually grow larger. During the expansion process, not only does the airbag 200 itself expand and come into contact with the inside of the anus 10, but the expansion of the airbag 200 also causes the supporting legs 320 to open away from the drainage main pipe 100, thereby squeezing the inner wall of the anus 10 and limiting the drainage main pipe 100, so that the multiple support members 300 are stretched around the drainage main pipe 100, thereby the drainage main pipe 100 can be stuck in the anus 10. During use of this solution, the drainage main pipe 100 is stably stuck in the anus 10 through the combined action of the airbag 200 and the surrounding support member 300. While the inflated airbag 200 expands in the anus 10, the support member 300 opens to shape the position of the airbag 200. When squeezed by the muscles in the anus 10, the support member 300 does not deform in the radial direction, so that the airbag 200 is not easily compressed in the radial direction, thus avoiding the problem of the distal end of the drainage main pipe 100 being squeezed and easily slipping out of the anus 10.

[0041] like Figure 1 、 Figure 5 As shown, further, in this embodiment, an inflation channel 110 is provided in the drainage main pipe 100, and the inflation channel 110 is connected to the airbag 200. An inflation connector 111 is provided at the proximal end of the drainage main pipe 100, and the inflation connector 111 is connected to the inflation channel 110. In the specific structure, during the molding process, a hole is opened on the wall of the drainage main pipe 100 in the direction from the distal end to the proximal end, and an orifice is formed on the distal outer wall of the drainage main pipe 100. During the process of bonding and fixing the airbag 200 to the outer wall of the drainage main pipe 100, the inlet of the airbag 200 is connected to the orifice of the inflation channel 110. The inflation connector is provided at the proximal end of the drainage main pipe 100 and protrudes from the outer wall. The inflation connector can be connected to an external inflation device, which can be a syringe (for injecting air). Therefore, air can be directly pushed into the inflation channel 110 through the syringe, and the airbag 200 is inflated through the inflation channel 110 to form an expanded state. The inflated airbag 200 can drive the support member 300 to open and be embedded in the anus 10 as a whole.

[0042] like Figure 3 、 Figure 4 、 Figure 5As shown, in the expanded state, the airbag 200 may include: an expansion support portion 210 and an expansion filling portion 220. The expansion support portion 210 is connected to the bottom of the support member 300, and the expansion filling portion 220 is filled between adjacent support members 300. In the specific structure, the airbag 200 has different expansion areas during the inflation process, and these expansion areas may not expand. For example, the thickness of the non-expanding area between the expansion areas is greater than the thickness of the expansion areas, or the space in the expansion area of the airbag 200 is relatively large. In this way, each expansion area expands after the entire airbag 200 is inflated, thereby forming the expansion support portion 210 and the expansion filling portion 220. After expansion, the expansion support portion 210 pushes up the support member so that the support member 300 opens. After expansion, the expansion filling portion 220 fills between each support member 300, thereby sealing the space formed after the support member 300 opens. In addition, the expanded expansion filling portion 220 also squeezes the inner wall of the anus 10 during the squeezing process, thereby preventing excrement from leaking out of the anus 10.

[0043] like Figure 2 、 Figure 3 、 Figure 4 As shown, further, a hinged seat 130 is provided on the outer wall of the drainage main pipe 100 in this embodiment. The hinged seat 130 is used to connect the support member 300, so that the support member 300 can be opened away from the central axis of the drainage main pipe 100. The support member 300 includes a support bar 310, one end of which is hinged to the hinged seat 130, and the end of the support bar 310 away from the hinged seat 130 forms a support foot 320. In the specific structure, the distal end of the support bar 310 can be rotatably connected to the hinged seat 130 via a hinge rod, and the proximal end of the support bar 310 forms a support foot 320. Therefore, when the support bar 310 is supported by the expansion support portion 210, the support foot 320 gradually opens away from the drainage main pipe 100. When the support bar 310 is opened, it can form a certain acute angle with the drainage main pipe 100, or directly form a right angle. By supporting the support legs 320 against the inner wall of the anus 10 and the expansion filling portion 220 also resting against the inside of the anus 10 after expansion, the position of the airbag 200 is shaped by the expanded support member 300, thereby achieving a more stable fixation of the drainage main pipe 100 in the anus 10.

[0044] It is easy to imagine that the support member 300 can also be fixedly connected to the outer wall of the drainage main pipe 100 via a flexible bending strip. The flexible bending strip can also deform during the process of the support bar 310 being supported by the expansion support part 210, causing the support legs 320 to gradually open away from each other, solving the technical problem of the present application.

[0045] like Figure 3 、 Figure 4As shown, the support foot 320 in this embodiment specifically includes an external protrusion located on the side of the support bar 310 facing away from the drainage main pipe 100 and arranged obliquely with respect to the extension direction of the support bar 310. The external protrusion protrudes from the surface of the support bar 310 and can be arranged obliquely with respect to the extension direction of the support bar 310, or even perpendicularly. This increases the contact area between the support bar 310 and the anus 10, thereby improving support stability.

[0046] Furthermore, a flexible adhesive layer is provided on the support leg 320 in this embodiment. The flexible adhesive layer reduces the squeezing strength of the support leg 320 on the inner wall of the anus 10, alleviates the stimulation reaction of the patient when using the drainage device, avoids the pain during use, and improves the user experience.

[0047] like Figure 2 、 Figure 3 、 Figure 4 As shown, further, in this embodiment, an inner groove 140 is defined on the outer wall of the drainage main tube 100. When the airbag 200 is in the deflated state, the support member 300 is accommodated in the inner groove 140. The connection point between the support member 300 and the drainage main tube 100 (e.g., the hinge seat 130 or the flexible bending strip) is also disposed within the inner groove 140 and does not protrude from the outer wall surface of the drainage main tube 100. The inner groove 140 serves as a receiving slot to accommodate the support member 300, preventing the support member 300 from protruding from the outer wall surface of the drainage main tube 100. This facilitates insertion of the drainage main tube 100 into the patient's anus 10 and improves ease of use.

[0048] like Figure 4 、 Figure 5 As shown, further, in this embodiment, the bottom of the inner groove 140 is connected to the outer wall of the airbag 200 via a first adhesive layer 211, and the surface of the support strip 310 facing the drainage main pipe 100 is also bonded and fixed to the airbag 200. The outer wall of the drainage main pipe 100 located between adjacent inner grooves 140 is connected to the outer wall of the airbag 200 via a second adhesive layer 221. As a result, the expansion support portion 210 is primarily located within the inner groove 140, and the expansion filling portion 220 is located between adjacent inner grooves 140. The airbag 200 wall corresponding to the first adhesive layer 211, the second adhesive layer 221, and other adhesive areas is relatively thick. This allows the expansion support portion 210 and the expansion filling portion 220 to be formed after expansion, thereby maintaining a stable connection between the airbag 200 and the support member 300, allowing the support member 300 to provide stable support for the inflated airbag 200.

[0049] like Figure 1 、 Figure 3As shown, further, in this embodiment, the drainage main pipe 100 is provided with an injection channel 120, which runs through the distal end of the drainage main pipe 100. The proximal end of the drainage main pipe 100 is provided with an injection connector 121, which is connected to the injection channel 120. In the specific structure, during the molding process, another hole is opened on the wall of the drainage main pipe 100 in a direction from the distal end toward the proximal end, forming an orifice on the distal end face of the drainage main pipe 100. When the drainage main pipe 100 is inserted into the anus 10, the hole on the end face of the drainage main pipe 100 is exposed inside the anus 10. The injection connector is provided at the proximal end of the drainage main pipe 100 and protrudes from the outer wall. The injection connector can be connected to an external injection device, which can be a syringe (for injecting liquid medicine). Therefore, liquid medicine can be directly pushed into the injection channel 120 via the syringe. It should also be noted that the injection channel 120 can be switched on and off by a valve to realize the function of a one-way channel, so that excrement can only be discharged through the drainage main pipe 100 but cannot be discharged from the injection channel 120 .

[0050] Furthermore, the outer wall of the drainage main tube 100 in this embodiment is provided with a scale marking portion, which is used to indicate the insertion depth of the drainage main tube 100 into the anus 10. The scale marking portion is a depth line, and during the insertion process into the anus 10, the medical staff can visually see the insertion depth of the drainage main tube 100 through the scale marking portion, which is convenient for use.

[0051] like Figure 1 As shown, in this embodiment, the proximal end of the drainage main pipe 100 is detachably connected to a drainage bag 150. A tube sealing clamp 160 is connected to the drainage main pipe 100. The tube sealing clamp 160 is used to close the proximal end of the drainage main pipe 100 to replace the drainage bag 150. The tube sealing clamp 160 allows the drainage bag 150 to be replaced during the tube sealing process, facilitating use.

[0052] In summary, the present application provides an internally supported anti-slip anal canal drainage device. During use, the drainage main pipe 100 is stably stuck in the anus 10 through the joint action of the airbag 200 and the surrounding support member 300. While the inflated airbag 200 expands in the anus 10, the support member 300 opens to shape the position of the airbag 200. When squeezed by the muscles in the anus 10, the support member 300 does not deform in the radial direction, so that the airbag 200 is not easily compressed in the radial direction, thereby avoiding the problem of the distal end of the drainage main pipe 100 being squeezed and easily slipping out of the anus 10.

[0053] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
