Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drainage and hemostasis device for the anus after operation. Background Art

[0002] Anus surgery refers to a surgical operation for treating anorectal diseases. Anus surgery generally causes an open wound. Due to the particularity of the surgical position, a drainage device needs to be set at the wound to discharge waste liquid, tissues and waste gas, so as to ensure the cleanliness of the wound. At present, the drainage devices on the market generally consist of a drainage tube and a hemostatic sponge. A through hole is dug in the hemostatic sponge, the drainage tube is inserted into the through hole, and then the hemostatic sponge and the drainage tube are placed at the anus. The hemostatic sponge plays a role in compressing and stopping bleeding at the anus wound, and the drainage tube can drain and discharge the waste liquid, tissues and waste gas generated at the wound. However, this traditional drainage device has the following defects: the hemostatic sponge is generally cylindrical in shape. When the hemostatic sponge is placed at the anus for compressing and stopping bleeding, the hemostatic sponge will cause an outward extrusion at the anus, which will not only cause serious discomfort to the patient, but also easily tear the wound at the anus, affecting wound healing; the matching tightness between the drainage tube and the hemostatic sponge is not easy to control. If the matching between the drainage tube and the hemostatic sponge is too loose, the drainage tube is likely to fall off. If the matching between the drainage tube and the hemostatic sponge is too tight, it will not only squeeze the drainage tube and cause deformation, affecting the drainage effect, but also easily cause the drainage tube to be blocked. After the drainage tube is blocked, since the matching between the drainage tube and the hemostatic sponge is too tight, the drainage tube cannot be replaced alone, and only the hemostatic sponge and the drainage tube can be replaced together. Moreover, when the amount of waste liquid is large, the hemostatic sponge will absorb a large amount of waste liquid, and at this time, the hemostatic sponge and the drainage tube need to be replaced frequently; and when the discharge amount of waste liquid, tissues and waste gas is large, it is generally within 24-48 hours after the operation. At this time, if the hemostatic sponge is replaced frequently, it is not conducive to wound healing. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a drainage and hemostasis device for the anus after operation, which does not need to frequently replace the conical sponge column and is convenient for separately replacing the drainage tube.

[0004] To achieve the above purpose, the technical scheme adopted by the utility model is: a drainage and hemostasis device for the anus after operation, comprising: a conical sponge column, an outer catheter and a drainage tube. The small-diameter end of the conical sponge column is set in a plum blossom shape. A reverse conical hole is arranged in the conical sponge column. The outer catheter is movably inserted into the reverse conical hole. The outer catheter is in interference fit with the lower half section of the reverse conical hole. A flared tray is arranged at the top of the outer catheter. A plurality of partition ribs are circumferentially and evenly arranged on the inner wall of the outer catheter. The drainage tube is movably inserted into the outer catheter and abuts against the partition ribs. A gap is left between the drainage tube and the outer catheter. A plurality of flow-aiding holes are arranged on the upper side wall of the drainage tube.

[0005] Further, for the aforementioned anal postoperative drainage and hemostasis device, a number of annular grooves are provided at intervals on the outer side wall of the conical sponge column.

[0006] Further, for the aforementioned anal postoperative drainage and hemostasis device, the aperture diameter of the large-diameter end of the inverted conical hole is 1 to 1.5 mm larger than the outer diameter of the outer catheter, and the aperture diameter of the small-diameter end of the inverted conical hole is 0.5 to 1 mm smaller than the outer diameter of the outer catheter.

[0007] Further, for the aforementioned anal postoperative drainage and hemostasis device, a medical breathable adhesive tape is pasted on the bottom wall of the conical sponge column. A through hole aligned with the inverted conical hole is provided on the medical breathable adhesive tape. A number of adhesive tapes extend outward on the medical breathable adhesive tape, and a release film is provided on the adhesive surface of the adhesive tape.

[0008] Further, for the aforementioned anal postoperative drainage and hemostasis device, a tray groove capable of accommodating the flared tray is provided on the top wall of the conical sponge column, and the tray groove communicates with the inverted conical hole.

[0009] Further, for the aforementioned anal postoperative drainage and hemostasis device, a rounded corner is provided on the top end wall of the drainage tube, a rounded corner is provided on the flared tray, and a rounded corner is provided on the flow-aid hole.

[0010] Further, for the aforementioned anal postoperative drainage and hemostasis device, a guiding inclined surface is provided between the partition rib and the inner wall of the outer catheter.

[0011] Further, for the aforementioned anal postoperative drainage and hemostasis device, both the outer catheter and the drainage tube are made of transparent soft silicone material. The outer catheter is longer than the conical sponge column, and the drainage tube is longer than the outer catheter.

[0012] The advantages of the present utility model are as follows: The conical sponge column can be conveniently placed at the anus. The small-diameter end of the conical sponge column is arranged in a plum blossom shape, which can better adapt to the curve and shape inside the anus, thereby increasing the contact area between the conical sponge column and the anal wall, and improving the hemostasis effect; when the conical sponge column is squeezed for compressive hemostasis, the annular grooves on the conical sponge column are deformed under pressure, reducing the deformation amount of the small-diameter end in contact with the anus from expanding outwards, so that the small-diameter end will not cause a large extrusion to the anus, reducing the discomfort of the patient, and will not cause tearing of the wound surface at the anus; an inverted conical hole is provided in the conical sponge column, and the outer catheter is movably inserted into the inverted conical hole. The outer catheter has an interference fit with the lower half of the inverted conical hole, which is convenient for installing the outer catheter and can ensure the assembly strength between the outer catheter and the conical sponge column. A flared tray is provided on the outer catheter to collect waste liquid, waste gas and tissues, preventing the conical sponge column from absorbing too much waste liquid and tissues and causing infection to the periphery of the wound surface, and also reducing the replacement frequency of the conical sponge column, which is beneficial to the healing of the wound surface; the drainage tube is movably arranged in the outer catheter and has a gap with the outer catheter under the action of the partition ribs. On the one hand, it can play a role in drainage. On the other hand, when the drainage tube is blocked, the drainage tube can be replaced separately. When replacing the drainage tube, it will neither affect the drainage and discharge of waste liquid, tissues and waste gas, nor affect the compressive hemostasis effect of the conical sponge column.

[0019] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] AsFigures 1 to 6 As shown in the figure, the anal postoperative drainage and hemostasis device of the present utility model includes: a conical sponge column 1, an outer catheter 2 and a drainage tube 3. The conical sponge column 1 is made of medical sponge material, and both the outer catheter 2 and the drainage tube 3 are made of transparent soft silicone material. The small-diameter end of the conical sponge column 1 is set in a plum blossom shape. A number of annular grooves 11 are arranged at intervals on the outer side wall of the conical sponge column 1. An inverted conical hole 12 is arranged in the conical sponge column 1. The aperture of the large-diameter end of the inverted conical hole 12 is 1 mm to 1.5 mm larger than the outer diameter of the outer catheter 2, and the aperture of the small-diameter end of the inverted conical hole 12 is 0.5 mm to 1 mm smaller than the outer diameter of the outer catheter 2. A tray groove 13 communicating with the inverted conical hole 12 is arranged on the top wall of the conical sponge column 1. A medical breathable adhesive tape 4 is pasted on the bottom wall of the conical sponge column 1. A through hole 41 aligned with the inverted conical hole 12 is arranged on the medical breathable adhesive tape 4. A number of adhesive tapes 42 extend outward on the medical breathable adhesive tape 4. A release film 43 is arranged on the adhesive surface of the adhesive tape 42.

[0021] A flared tray 21 that can be inserted into the tray groove 13 is arranged at the top of the outer catheter 2. Fillets are arranged on the flared tray 21. A number of partition ribs 22 are evenly distributed in a circumferential direction on the inner wall of the outer catheter 2. A guiding inclined surface 221 is arranged between the partition rib 22 and the inner wall of the outer catheter 2. The outer catheter 2 is movably inserted into the inverted conical hole 12, and the lower half of the outer catheter 2 is in interference fit with the inverted conical hole 12. During the insertion process, the outer catheter 2 is inserted into the inverted conical hole 12 from top to bottom. The bottom of the outer catheter 2 first extends downward into the large-diameter end of the inverted conical hole 12. Since the large-diameter end of the inverted conical hole 12 is larger than the outer catheter 2, the outer catheter 2 can smoothly extend into the inverted conical hole 12. Then, the outer catheter 2 is pushed downward with force. Since the outer catheter 2 is longer than the conical sponge column 1, the bottom of the outer catheter 2 and the flared tray 21 both extend out of the conical sponge column 1. Since the lower diameter end of the inverted conical hole 12 is 0.5 mm to 1 mm smaller than the outer catheter 2, the conical sponge column 1 will be tightly attached to the outer catheter 2 under the action of elastic force, which can play a good fixing role without causing extrusion deformation to the outer catheter 2.

[0022] Fillets are arranged on the top end wall of the drainage tube 3. A number of flow-aiding holes 31 are arranged on the upper side wall of the drainage tube 3. Fillets are arranged on the flow-aiding holes 31. The drainage tube 3 is movably inserted into the outer catheter 2 and abuts against the partition rib 22. During the insertion process, the drainage tube 3 is inserted into the outer catheter 2 from bottom to top. Since there is a guiding inclined surface 221 in the outer catheter 2, the drainage tube 3 can be smoothly inserted into the outer catheter 2 and contact the partition rib 22 under the action of the guiding inclined surface 221, so that a gap is left between the drainage tube 3 and the outer catheter 2. Under the action of the elastic force of the conical sponge column 1, the partition rib 22 of the outer catheter 2 can play a high clamping role on the drainage tube 3. The drainage tube 3 is longer than the outer catheter 2, so that both the top and bottom of the drainage tube 3 can extend out of the outer catheter 2.

[0023] When in use, first pull down the outer catheter 2 to immerse the flared tray 21 on the outer catheter 2 into the tray groove 13 of the conical sponge column 1. Then pull down the drainage tube 3 to immerse the top of the drainage tube 3 into the outer catheter 2. Then place the conical sponge column 1 at the anus, and the top of the conical sponge column 1 contacts the anus. Since the diameter of the top of the conical sponge column 1 is smaller and the top of the conical sponge column 1 is in a plum blossom shape, the conical sponge column 1 can more conveniently extend into the anus, and the plum blossom-shaped top can better adapt to the curve and shape inside the anus, thereby increasing the contact area between the conical sponge column 1 and the anal wall, and thus improving the hemostasis effect. To further improve the compression hemostasis effect of the conical sponge column 1, the conical sponge column 1 will be subjected to a certain amount of extrusion. After being extruded, the conical sponge column 1 will cause the annular groove 11 to be compressed and deformed, reducing the amount of deformation of the conical sponge column 1 expanding outwards. And because the small-diameter end of the top of the conical sponge column 1 contacts the anus, the expansion of the small-diameter end will not cause a large extrusion to the anus, reducing the discomfort of the patient, and will not cause tearing to the wound surface at the anus. Then tear off the release film 43 on the four adhesive tapes 42 of the medical breathable adhesive tape 4, and stick the adhesive tape 42 on the patient's buttocks to play a fixing role. Then push the outer catheter 2, so that the flared tray 21 on the outer catheter 2 abuts against the periphery of the surgical wound. Since there are rounded corners on the flared tray 21, the flared tray 21 can reduce the discomfort of the patient when contacting the patient's skin. Finally, push the drainage tube 3 so that the drainage tube 3 contacts the wound surface. There are rounded corners on the top end wall and the flow-assisting holes 31 of the drainage tube 3, which can reduce the discomfort when contacting the wound surface. The waste liquid, tissue and waste gas flowing out of the wound surface will be drained outwards from the drainage tube 3. When the waste liquid is excessive, the flared tray 21 can gather most of the waste liquid to reduce the amount of waste liquid flowing onto the conical sponge column 1, preventing the conical sponge column 1 from absorbing too much waste liquid and causing infection to the periphery of the wound surface. The waste liquid gathered in the flared tray 21 can flow into the drainage tube 3 through the flow-assisting holes 31 of the drainage tube 3 to accelerate the outflow of the waste liquid, and will also flow out from the gap between the drainage tube 3 and the outer catheter 2. The bottom of the outer catheter 2 can be connected to a drainage bag through a common rubber tube. When the drainage tube 3 is blocked by blood clots or tissue, the waste liquid and waste gas can be discharged outwards from the gap between the drainage tube 3 and the outer catheter 2, preventing the situation that the waste liquid and waste gas accumulate in the wound surface due to untimely disposal, resulting in wound surface infection. When the drainage tube 3 is blocked, only need to pull out the drainage tube 3 and insert a new drainage tube 3. When inserting and pulling out the drainage tube 3, it will not affect the discharge of the waste liquid and waste gas. And due to the guiding effect of the partition rib 22 in the outer catheter 2, the drainage tube 3 can very smoothly extend to the wound surface.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit it. Although the present utility model has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications or equivalent substitutions can still be made to the specific implementation manners of the present utility model, and any modification or equivalent substitution that does not depart from the spirit and scope of the present utility model shall be covered by the protection scope of the claims of the present utility model.
