Description

Technical Field

[0001] This utility model relates to the technical field of the A61M1 / 00 medical drainage system, specifically a drainage tube leakage suction mechanism and an abdominal drainage tube anti-leakage drainage device. Background Technology

[0002] Drainage tubes are used to drain fluid from the body. The most common type of drainage tube in clinical practice is the abdominal drainage tube, which is used to drain fluid from the abdominal cavity after abdominal surgery. When using a drainage tube, there is often leakage of bodily fluid at the contact point between the outer wall of the drainage tube and the skin, resulting in a poor experience for the patient and requiring constant cleaning by medical staff.

[0003] To address the aforementioned technical problems, Chinese patent document CN221431680U proposes an anti-leakage drainage bag for abdominal drainage tubes. This bag utilizes the structure of existing ostomy bags, using an adhesive base to surround the stoma of the abdominal drainage tube, allowing exudate from the outer wall of the tube to enter the bag for collection. The tube is then inserted into the bag to drain tissue fluid from within. The drawback of this solution is that the complete wrapping of the skin incision keeps the incision surface constantly moist, making it prone to bacterial growth and hindering wound health and recovery.

[0004] Chinese patent document CN213554160U discloses a drainage tube reinforcement fixation dressing. This dressing includes a dressing body for fixing the drainage tube to the patient's skin. The dressing body includes a visible area, a dressing area, an adhesive area, and a reinforcement fixation area. The visible area is located above the drainage tube puncture point. The dressing area surrounds the visible area and absorbs blood and exudate around the puncture point. The adhesive area surrounds the dressing area, and its lower surface is adhered to the patient's skin. A reinforcement fixation area is located at the edge of the adhesive area, perpendicular to the drainage tube. Four vertical adhesive strips are provided on the reinforcement fixation area. The two middle adhesive strips are wrapped around and fixed to the drainage tube, while the two outer adhesive strips are adhered to the patient's skin. This design improves the stability of the connection between the drainage tube and the patient, but it also suffers from the drawbacks of the previous patent document because it cannot effectively drain blood and exudate.

[0005] To promptly remove exudate, Chinese patent document CN212214268U discloses a portable exudate suction device, which includes a negative pressure suction device and a storage bottle connected to the negative pressure suction device via a negative pressure pipe. An exudate diversion tube is also connected to the storage bottle, and the end of the exudate diversion tube away from the storage bottle is connected to a suction tube for suctioning the exudate. The sidewall of the suction tube has a suction layer that penetrates the sidewall of the suction tube. This solution can promptly remove exudate through negative pressure suction, which is beneficial for wound drying and healing. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drainage tube leakage absorption mechanism that can promptly drain the tissue fluid seeping along the drainage tube, keeping the skin incision in a relatively ventilated and dry environment, while also improving the stability of the connection between the drainage tube and the patient's body.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] The drainage tube leakage suction mechanism includes

[0009] A sheath is used to surround the outer wall of the drainage tube. The side wall has a longitudinal inlet for locking onto the drainage tube, and the lower part has a receiving cavity and an absorption hole for draining tissue fluid.

[0010] An absorbent pad, at least one in number, has an annular cross-section and is provided with a locking slit for fitting it onto the drainage tube to absorb tissue fluid seeping from the surface of the drainage tube; the absorbent pad blocks the absorbent holes of the sheath when placed in the receiving cavity;

[0011] The permeate suction tube has one end fixed to the outside of the sheath and connected to the absorption hole, and the other end connected to a permeate storage bag that can be connected to a negative pressure connection. The permeate storage bag has a permeate negative pressure tube.

[0012] The adhesive part is fixed to the bottom periphery of the sheath and is used to fix the sheath above the skin incision; the adhesive part is provided with a transverse inlet for the drainage tube to pass through.

[0013] The inventive concept is as follows: A replaceable absorbent pad is added to the connection between the drainage tube and the skin incision. When tissue fluid leaks out, it is first absorbed by the absorbent pad and then drawn into the permeate reservoir by the negative pressure of the permeate suction tube. When the amount of tissue fluid leaking out is large, some of the tissue fluid may dry and clump inside the absorbent pad, affecting its ability to continue absorbing tissue fluid; in this case, the pad can be replaced. Furthermore, because the skin incision covered by the absorbent pad is always connected to the outside air, the skin incision remains dry, which is beneficial for recovery. Thirdly, the connection between the drainage tube and the skin incision is also wrapped by a sheath and absorbent pad. When the drainage tube is accidentally pulled by external force, the sheath acts as a buffer, which helps improve the stability of the connection between the drainage tube and the patient's body. Fourthly, the longitudinal inlet of the sheath and the transverse inlet of the adhesive part facilitate its use with the drainage tube. A mechanism for absorbing leakage from the drainage tube can be added to the traditional drainage tube usage, allowing for on-demand use.

[0014] As an improvement, the sheath has a convex cross-section, and the absorbent pad is cylindrical and located at the lower part of the convex shape. The upper part of the convex shape surrounds the drainage tube and makes surface contact with the drainage tube, thus providing better resistance to external force when the drainage tube is accidentally pulled.

[0015] As an improvement, the sheath has a frustum-shaped axial section, and the absorbent pad is cylindrical and located at the lower part of the frustum, so that the lateral pressure on the upper part of the absorbent pad is greater than the lateral pressure on the lower part. This design makes it difficult for tissue fluid to move towards the upper part of the absorbent pad, which is beneficial for the exudate to be drawn out of the absorbent pad by the permeation fluid suction tube.

[0016] As a further improvement, the absorbent hole is located at the bottom of the absorbent pad, which can promptly absorb tissue fluid seeping from the skin incision.

[0017] As an improvement, the absorbent pad is made of gelatin sponge.

[0018] This application also provides another type of drainage tube leakage suction mechanism, including

[0019] The sheath is used to surround the outer wall of the drainage tube. The lower part forms a receiving cavity. The receiving cavity has a replacement channel for inserting the absorbent pad. The sheath has an absorbent hole for draining tissue fluid at the position of the receiving cavity.

[0020] An absorbent pad, at least one in number, has an annular cross-section and is provided with a locking slit for fitting it onto the drainage tube to absorb tissue fluid seeping from the surface of the drainage tube; the absorbent pad blocks the absorbent holes of the sheath when placed in the receiving cavity;

[0021] The permeate suction tube has one end fixed to the outside of the sheath and connected to the absorption hole, and the other end connected to a permeate storage bag that can be connected to a negative pressure connection. The permeate storage bag has a permeate negative pressure tube.

[0022] The adhesive part is fixed to the bottom periphery of the sheath and is used to secure the sheath above the skin incision.

[0023] The sheath shown in this scheme needs to be pre-installed on the drainage tube. Its advantage is that the drainage tube will not separate from the sheath and can resist external forces from all directions.

[0024] This application also provides an abdominal drainage tube anti-leakage device, including a drainage tube, one end of which is connected to a drainage bag, and a drainage fluid negative pressure tube is connected to the drainage bag; it also includes a drainage tube leakage suction mechanism as described above; the leakage fluid suction mechanism of the drainage tube leakage suction mechanism is connected to the drainage fluid negative pressure tube through a T-connector.

[0025] As an improvement, the permeate negative pressure pipe and the drainage negative pressure pipe are equipped with flow regulating valves.

[0026] In summary, this utility model has the advantages of simple structure and convenient use. The combination of the sheath and the absorbent pad helps to improve the stability of the connection between the drainage tube and the patient's body. The exudate is first absorbed by the absorbent pad and then suctioned away by the permeation fluid suction tube, which can effectively prevent the overflow of exudate. The replaceable absorbent pad helps to ensure its patency and keeps the skin incision in a relatively ventilated and dry environment, which is conducive to the recovery of the condition.

[0034] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0035] Example 1

[0036] like Figure 1 , Figure 2As shown, the main body of the drainage tube leakage absorption mechanism described in this application consists of a sheath 11 and an absorbent pad 12 used in conjunction with it. The sheath 11 is made of medical-grade silicone and can be used for a long time. The absorbent pad 12 is made of gelatin sponge and is used to absorb tissue fluid seeping from the surface of the drainage tube 10. Several pads are provided, and they can be replaced as needed. The absorbent pad 12 can also be made of other absorbent materials. A ring of adhesive portion 14 is provided around the bottom periphery of the sheath 11, which is used to fix the sheath 11 above the skin incision. The adhesive portion 14 has a transverse inlet 141 for the drainage tube 10 to pass through. The side wall of the sheath 11 has a longitudinal inlet 111 for engaging with the drainage tube 10. The sheath 11 and the adhesive portion 14 can be integrally formed. When the drainage tube 10 is in working condition, the sheath 11 can be assembled to the connection between the drainage tube 10 and the skin incision through the longitudinal inlet 111 and the transverse inlet 141, and surround the outer wall of the drainage tube 10.

[0037] like Figure 2 , Figure 3 As shown, the sheath 11 has a frustum-shaped cross-section, and the lower part of the sheath 11 forms a receiving cavity 112 and an absorption hole 113 for draining tissue fluid. The absorbent pad 12 is cylindrical with an annular cross-section, and one side has an insertion slot 121 for fitting it onto the drainage tube 10. Medical personnel can use tweezers to insert it into the receiving cavity 112 through the longitudinal inlet 111 of the sheath 11. After insertion, the absorbent pad 12 is located at the lower part of the frustum-shaped sheath 11 and can block the absorption hole 113 of the sheath 11, which is located at the lower part of the absorbent pad 12. After the absorbent pad 12 is fixed in the receiving cavity 112, the lateral pressure on its upper part is greater than the lateral pressure on its lower part. When it is necessary to replace the absorbent pad 12, medical personnel can use tweezers to grasp it and pull it outward to remove the absorbent pad 12 from the receiving cavity 112.

[0038] The outer wall of the sheath 11 is also provided with a permeate suction tube 13. One end of the permeate suction tube 13 is fixed to the outside of the sheath 11 and communicates with the absorption hole 113. The other end is connected to a permeate storage bag 131 that can be connected to a negative pressure connection. The permeate storage bag 131 has a permeate negative pressure tube 132, which is used to connect to an external negative pressure.

[0039] Example 2

[0040] This embodiment describes an abdominal drainage tube with a leakage suction mechanism, such as... Figure 4 As shown, it also includes a drainage tube 10, a drainage bag 21, and a drainage fluid negative pressure tube 22. One end of the drainage tube 10 is connected to the drainage bag 21, and the drainage bag 21 is also connected to the drainage fluid negative pressure tube 22. The permeate negative pressure tube 132 of the drainage tube leakage suction mechanism is connected to the drainage fluid negative pressure tube 22 via a T-joint 23. Both the permeate negative pressure tube 132 and the drainage fluid negative pressure tube 22 are equipped with flow regulating valves 24.

[0041] As an obvious variation, the permeate negative pressure tube 132 of the drainage tube permeate absorption mechanism can also be connected separately to a manual negative pressure ball. When the permeate volume is small, intermittent manual negative pressure suction can be applied to the absorption hole 113.

[0042] Example 3

[0043] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the axial section of the sheath 11 is convex, the lower part of the convex shape is the receiving cavity 112, and the absorbent pad 12 is cylindrical and located inside the receiving cavity 112. The inner diameter of the upper part of the convex shape can be slightly larger than the outer diameter of the drainage tube 10, so that the upper part of the convex shape can make surface contact with the drainage tube 10, and the effect of resisting external force traction is better when the drainage tube 10 is accidentally pulled by external force.

[0044] Example 4

[0045] like Figure 6 As shown, the difference between this embodiment and embodiment 3 is that the sheath 11 does not have a longitudinal inlet 111, and the adhesive part 14 does not have a transverse inlet 141. Therefore, the drainage tube 10 needs to be covered with the sheath 11 first, and then connected to other components. To facilitate the replacement of the absorbent pad 12, a replacement channel 114 is provided on the sheath 11, which is located at the lower part of the sheath 11. Because this solution eliminates the longitudinal inlet 111 and the transverse inlet 141, the drainage tube 10 will not separate from the sheath 11 when subjected to external forces in all directions. In addition, the convex upper part of the sheath makes surface contact with the drainage tube 10, which can greatly improve the connection stability between the drainage tube 10 and the patient's body.
