Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an anal tube for post-operative hemostasis, drainage and exhaust in anorectal surgery. Background Art

[0002] After anorectal surgery, there is often a risk of bleeding at the surgical site. Traditional gauze compression hemostasis methods may not be effective enough and are inconvenient to operate. At the same time, after surgery, fluid or exudate may accumulate at the surgical site. If these effusions or exudates are not discharged in time, they may cause infection or affect wound healing; after anorectal surgery, patients may experience intestinal flatulence. Intestinal flatulence not only increases the patient's discomfort, but may also affect the recovery of intestinal function. Therefore, nurses generally use an anal tube to help patients stop bleeding, drain and exhaust.

[0003] Usually when the nurse takes the anal canal out of the patient's body, since there is liquid in the hemostasis and drainage process, some liquid (blood or fluid, etc.) will inevitably adhere to its surface when the anal canal is taken out. If the nurse is not careful, these liquids may fall off the surface of the anal canal and adhere to the patient's body or the equipment on the bed (sheets or quilts), increasing the difficulty of cleaning.

[0004] Therefore, the present invention proposes an anal tube for postoperative hemostasis, drainage and exhaust in anorectal surgery. When the anal tube is taken out from the patient's body, the liquid on its surface is quickly collected to reduce the possibility of adhesion to the patient's skin or bed equipment, which increases the difficulty of cleaning. Summary of the invention

[0005] To solve the above problems, the present invention provides an anal tube for postoperative hemostasis, drainage and exhaust in anorectal surgery. When the anal tube is taken out of the patient's body, the liquid on its surface is quickly collected to reduce the possibility of adhesion to the patient's skin or bed equipment, which increases the difficulty of cleaning.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an anal tube for post-operative hemostasis, drainage and exhaust in the anorectal department, comprising an anal tube, with an exhaust port and an air inlet at both ends respectively, a fixed component for stabilizing the anal tube in the patient's body is arranged on the surface of one end of the anal tube close to the air inlet, a sliding sleeve is ringed on the anal tube and the anal tube and the sliding sleeve are slidably matched, an annular collecting groove is opened at one end of the sliding sleeve close to the air inlet, a plurality of suction chambers are connected below the collecting groove, pistons are slidably matched in the suction chambers, and pull rods are fixedly connected to the bottoms of the pistons; an annular moving groove is opened inside the sliding sleeve, a moving ring is arranged in the moving groove and is ringed on the surface of the anal tube; the pull rods extend through the suction chamber to the moving groove at one end away from the piston and are fixedly connected to the top of the moving ring; the connecting rods are slidably matched with the sliding sleeve.

[0007] Principle of the basic solution: When the anal canal is taken out, the sliding shell is made to slide along the anal canal, so that the surface of the anal canal is quickly scraped into the collection groove inside the sliding shell. At the same time, when the sliding shell slides, the friction force is used to drive the moving ring that fits it, and then the moving ring pulls the connecting rod and the piston to quickly suck the liquid in the collection groove into the suction cavity, reducing the possibility of the surface liquid of the anal canal splashing onto the patient's skin surface or bed equipment when the anal canal is taken out.

[0008] The above scheme has the following beneficial effects:

[0009] Compared with the prior art, this solution utilizes the design of a sliding sleeve and a collection tank to quickly collect the liquid on the surface of the anal canal when it is removed into the collection tank, and generates negative pressure in the suction chamber by the movement of the piston to suck the liquid in the collection tank into it. Thus, by designing structures such as the sliding sleeve and the collection tank, this device can effectively reduce the residual and splashing of the surface liquid when it is removed, thereby avoiding the irritation and contamination of the patient's skin by the liquid, improving the patient's postoperative comfort, and at the same time enabling medical staff to more conveniently and quickly handle the residual liquid on the surface when removing the anal canal, reducing the operation steps and time, improving work efficiency, and at the same time reducing the risk of liquid splashing due to improper operation.

[0010] Furthermore, the fixing component includes a fixing air bag arranged on the surface of the anal canal, and the fixing air bag is connected to an air pump.

[0011] Beneficial effect: The fixed airbag is inflated by an air pump, thereby stabilizing the anal canal entering the patient's body in the patient's body, reducing the risk of the anal canal falling out of the patient's body when the patient moves.

[0012] Furthermore, a limit buckle is provided on the surface of the sliding sleeve, and the limit buckle is located within the movement track of the moving groove.

[0013] Beneficial effect: The sliding of the movable ring is limited by the limit buckle, thereby preventing the movement of the movable ring during the early stage of placement in the anal canal from affecting the effect of the liquid treatment on its surface when the anal canal is removed.

[0014] Furthermore, an anti-skid layer is provided on the surface of the sliding sleeve.

[0015] Beneficial effects: The design of the anti-slip layer increases the friction between the medical staff's hands and the sliding sleeve, making it possible to more stably control the movement trajectory and speed of the sliding sleeve when pushing or rotating it, avoiding operational errors and patient discomfort caused by slippage or loss of control, and further improving the efficiency of handling residual liquid on the surface of the anal canal.

[0016] Furthermore, the top width of the collecting tank is greater than the bottom width.

[0017] Beneficial effect: The design that the top width of the collecting groove is larger than the bottom width can facilitate some residual liquid with a large volume on the surface of the anal canal to enter the collecting groove and be collected, thereby further improving the efficiency of liquid treatment on the surface of the anal canal.

[0018] Furthermore, the bottom of the collecting tank is an arc-shaped structure.

[0019] Beneficial effect: The arc-shaped structure at the bottom of the collection tank can guide the liquid to flow more smoothly to the suction chamber. Compared with the linear or flat bottom structure, the arc-shaped structure can reduce the resistance and turbulence of the liquid during the flow process, making the liquid more evenly distributed at the entrance of the suction chamber, thereby improving the suction efficiency.

[0020] Furthermore, the cross section of the collecting tank is V-shaped.

[0021] Beneficial effects: The V-shaped cross-section of the collection groove has natural guidance and can more effectively guide the liquid to flow along the bottom of the collection groove. As the two side walls of the V-shaped groove gradually shrink inward, the water droplets will be subject to a gradually increasing restraining force during the flow, making it easier to be guided to the center of the groove bottom and then collected, significantly improving the liquid collection efficiency and reducing the liquid residue and splashing outside the groove. At the same time, with the arc structure at the bottom, the liquid's own tension is used to stabilize it in the collection groove, thereby reducing the possibility of liquid flowing out of the collection groove and further ensuring the stability of subsequent absorption.

[0022] Furthermore, the connection point between the collecting groove and the suction chamber is defined as a suction channel, and the diameter of the suction channel at one end close to the suction chamber is larger than that at the other end.

[0023] Beneficial effects: The diameter of the suction channel near the suction chamber is larger, which can reduce the resistance of the liquid during the flow process. At the same time, as the diameter of the pipe gradually decreases, the speed of the fluid will gradually increase, which helps to form a certain negative pressure in the suction channel, thereby more effectively sucking the liquid from the collection tank into the suction chamber, and at the same time preventing the liquid sucked into the suction chamber from flowing from the suction chamber into the collection tank.

[0024] Furthermore, the diameter of the air inlet is larger than the diameter of the middle part of the anal canal.

[0025] Beneficial effect: The design of the air inlet diameter being larger than the middle diameter of the anal canal can further increase the friction between the air inlet and the moving ring when the air inlet moves to the moving ring, thereby ensuring that the moving ring can stably move to the maximum distance to fully collect the liquid in the collection tank.

[0026] Furthermore, there is an interference fit between the anal canal and the movable ring.

[0027] Beneficial effect: The friction between the moving ring and the anal canal is further increased, thereby ensuring that when the sliding sleeve slides along the anal canal, sufficient power can be provided for the moving ring to move, so as to pull the piston and generate sufficient negative pressure in the suction chamber, thereby collecting the liquid in the collection tank.

[0028] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following is further described in detail through specific implementation methods:

[0037] Embodiment 1:

[0038] As attached Figure 1 , Figure 2 and Figure 3 As shown: an anal tube for postoperative hemostasis, drainage and exhaust in anorectal surgery, comprising an anal tube 1, with exhaust ports 102 and air inlets 101 at the two ends thereof respectively. Medical staff can deliver the anal tube 1 into the patient's body so that the liquid or gas therein flows to the exhaust port 102 through the air inlet 101 of the anal tube 1, and is collected outside the patient's body for subsequent centralized treatment; a fixing component for stabilizing the anal tube 1 in the patient's body is arranged on the surface of one end of the anal tube 1 close to the air inlet 101, a sliding sleeve 5 is sleeved on the anal tube 1, and the anal tube 1 and the sliding sleeve 5 are in sliding cooperation, and an annular collecting groove 4 is opened at one end of the sliding sleeve 5 close to the air inlet 101. When the medical staff takes out the anal tube 1 from the patient's body after the exhaust and drainage (the sliding sleeve 5 is always outside the patient's body), they hold the anal tube 1 and the sliding sleeve 5 respectively, so that the two slide relative to each other, thereby using the edge of the collecting groove 4 on the sliding sleeve 5 to scrape the liquid remaining on the surface of the anal tube 1 into the collecting groove 4, and at the same time, in order to further improve the efficiency of scraping and collecting. The top width of the collecting groove 4 is greater than the bottom width, and the bottom of the collecting groove 4 is an arc-shaped structure and the cross-section of the collecting groove 4 is V-shaped, so that the collected liquid can move quickly to the bottom of the collecting groove 4. At the same time, due to the inertia of the sliding shell 5 when moving, the liquid will also quickly converge to the bottom of the collecting groove 4 and stably adhere to the bottom of the collecting groove 4. The arc-shaped structure at the bottom of the collecting groove 4 is used to adjust the shape of the liquid convergence, so that the tension of the liquid formed by its convergence can further enhance the adhesion of the liquid itself to the collecting groove 4, improve the stability during collection, and reduce the possibility of it detaching from the collecting groove 4.

[0039] There are several suction chambers 7 connected below the collecting tank 4. Pistons 13 are slidably fitted in the suction chambers 7. Pull rods are fixedly connected to the bottom of the pistons 13. The connecting rods 12 are slidably fitted with the sliding housing 5. An annular moving groove 10 is opened inside the sliding housing 5. A moving ring 11 is arranged in the moving groove 10 and is sleeved on the surface of the anal canal 1. The ends of the pull rods away from the pistons 13 pass through the suction chamber 7 and extend into the moving groove 10 and are fixedly connected to the top of the moving ring 11. The anal canal 1 and the moving ring 11 are interference fit. At the same time, a limiting buckle 8 is arranged on the surface of the sliding housing 5. The limiting buckle 8 is located in the motion trajectory of the moving groove 10. The sliding of the moving ring 11 is limited by the limiting buckle 8, so as to avoid the movement of the moving ring 11 during the early placement of the anal canal 1 affecting the effect of the surface liquid treatment when the anal canal 1 is removed. When the anal canal 1 is removed, the limiting buckle 8 only needs to be removed to release the restriction on the moving ring 11, so that it can move along the moving groove 10.

[0040] When the anal canal 1 and the sliding sleeve 5 slide relative to each other, due to the interference fit between the anal canal 1 and the moving ring 11, the friction between the anal canal 1 and the moving ring 11 can pull the moving ring 11 to move in the moving groove 10, thereby synchronously pulling the connecting rod 12 and the piston 13 to generate negative pressure in the suction chamber 7. The connection between the collecting groove 4 and the suction chamber 7 is set as a suction channel 6. The diameter of the suction channel 6 close to the suction chamber 7 is larger than the other end, so that the liquid collected in the collecting groove 4 is quickly sucked into the suction chamber 7. At the same time, by utilizing the structural characteristics of the suction channel 6 (the diameter of the suction channel 6 close to the suction chamber 7 is larger than the other end) and the liquid tension, it is difficult for the liquid entering the suction chamber 7 to enter the collecting groove 4 from the suction chamber 7 through the suction channel 6, thereby improving the stability of cleaning. At the same time, the diameter of the air inlet 101 is larger than the middle diameter of the anal canal 1, so as to ensure that when the air inlet 101 moves to the moving ring 11, the friction between the air inlet 101 and the moving ring 11 can be further increased, thereby ensuring that the moving ring 11 can stably move to the maximum distance to fully collect the liquid in the collection tank 4.

[0041] Embodiment 2:

[0042] The difference from the above embodiment is that, Figure 1 As shown, the fixing assembly includes a fixing airbag 2 arranged on the surface of the anal canal 1, and the fixing airbag 2 is connected to an inflation pump 3. After the medical staff places the anal canal 1 in the patient's body, it is generally necessary to take it out after a period of time (i.e., after waiting for the exhaust and drainage to be completed). During the period of time when the anal canal 1 is placed in the patient's body, it may deviate from the original position or even fall off due to the movement of the patient's body. The fixing airbag 2 is inflated by the inflation pump 3 to gradually expand, and stably support the patient's body, thereby improving the efficiency of hemostasis, drainage and exhaust.

[0043] Embodiment 3:

[0044] The difference from the above embodiment is that, Figure 1 As shown, an anti-skid layer 9 is bonded to the surface of the sliding shell 5. The anti-skid layer 9 can be made of fine rubber particles or silicone materials, which are soft and have good friction. When the medical staff holds the sliding shell 5, the anti-skid layer 9 increases the friction between the medical staff and the sliding shell 5, thereby reducing operational errors and unnecessary repeated actions.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
