Description

Technical Field

[0001] The utility model relates to a medical appliance, in particular to an ostomy bag accessory for drainage of effusion. Background Art

[0002] In modern medical clinical diagnosis and treatment, the excess fluid such as blood, pus and body fluid in the patient's body is drained out through a fistula tube and collected in a drainage bag, thereby effectively preventing infection. However, the liquid easily seeps out along the side of the fistula tube, and medical staff usually use a stoma bag to collect the exudate, thereby preventing the exudate from contaminating and corroding the patient's skin over a large area, causing dermatitis, wound infection and other complications. For reference, the fistula tube leakage collection device disclosed in the existing CN208741245U can be used.

[0003] Traditional ostomy bags can only collect ostomy exudate, and cannot collect the drainage fluid in the ostomy tube and the ostomy exudate in the ostomy bag into the same drainage bag. Medical staff need to check the amount of ostomy exudate reserves and discharge it in time, which increases their workload.

[0004] Therefore, how to design an ostomy bag accessory that can gather drainage fluid and stoma exudate and collect them into a drainage bag has become an urgent problem to be solved in the field of medical devices. Utility Model Content

[0005] The utility model aims to provide an ostomy bag accessory for drainage of effusion, which can gather ostomy exudate in the ostomy bag cavity and drainage fluid in the ostomy tube, and collect them into the drainage bag cavity. Medical staff do not need to actively discharge ostomy exudate in the ostomy bag cavity, thereby reducing the workload of medical staff.

[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0007] An ostomy bag accessory for drainage of effusion comprises an inner cover and an outer cover. The inner groove surface of the inner cover is provided with a drainage hole and a tube socket, and the ostomy exudate in the ostomy bag cavity flows into the drainage hole. The ostomy tube extending from the patient's body is placed in the ostomy bag cavity and connected to the tube socket, and the drainage fluid in the ostomy tube flows into the tube socket. The inner circumference of the outer cover is threadedly connected with the outer circumference of the inner cover, and the ostomy bag mouth can be sealed and clamped between the outer cover and the inner cover, so that the inner cover seals the ostomy bag cavity. The outer end surface of the inner cover is connected to a confluence piece, and a main joint is provided outside the confluence piece. The drainage hole and the tube socket are respectively connected to the main joint, and the ostomy exudate in the drainage hole and the drainage fluid in the tube socket converge in the main joint.

[0008] Compared with the prior art, the ostomy bag accessory for drainage of effusion using the above technical solution has the following beneficial effects:

[0009] 1. With the ostomy bag accessory for drainage of effusion of the utility model, medical staff put the ostomy tube through the opening of the ostomy bag bottom plate into the ostomy bag cavity, and then connect the ostomy tube head to the tube socket. When the effusion is drained, the ostomy exudate in the ostomy bag cavity and the drainage fluid in the ostomy tube are gathered in the main joint, and are collected into the drainage bag cavity through the drainage bag catheter. Medical staff do not need to actively discharge the ostomy exudate in the ostomy bag cavity, which reduces the workload of medical staff.

[0010] Second, the outer cover and the inner cover are connected by threads and clamped on the bag opening of the ostomy bag, which has better firmness and airtightness, making it difficult for stoma exudate to leak from the bag opening of the ostomy bag, and the assembly is simple.

[0011] Preferably, the tube socket is provided with an internal thread, so that the tube socket can be threadedly connected to the fistula tube head with an external thread. The tube socket and the fistula tube are threadedly connected, which has better firmness and airtightness, and prevents the fistula tube from being accidentally disconnected, resulting in a large amount of fluid in the ostomy bag cavity.

[0012] Preferably, the tube socket adopts a standard Luer connector, which can clamp the wall of the fistula tube to improve firmness and airtightness.

[0013] Preferably, the inner cover is detachably connected to the confluence piece. A bag joint and a tube joint are provided on the outer end surface of the inner cover, the bag joint is connected to the drainage hole, and the tube joint is connected to the tube socket. The confluence piece is provided with a bag interface and a tube interface on the surface connecting with the inner cover, the bag joint is clamped in the bag interface, and the tube joint is clamped in the tube interface. After the confluence piece is removed, the bag joint and the tube joint are exposed, and medical staff can connect two different drainage bag catheters to the bag joint and the tube joint respectively, so that the stoma exudate and the drainage fluid can be collected separately.

[0014] Preferably, the outer circumference of the bag joint and the outer circumference of the tube joint are both provided with a limiter, and the outer diameter of the limiter is larger than the inner diameter of the bag interface and the inner diameter of the tube interface. When the confluence piece is inserted until it touches the limiter, a gap is left in the confluence piece at the end of the bag joint and the end of the tube joint. Stoma exudate in the bag joint and drainage fluid in the tube joint can flow into the main joint through the gap. The limiter has a limiting effect on the bag joint and the tube joint, respectively, so that a sufficiently large gap is left in the confluence piece for the stoma exudate and drainage fluid to converge, and ensure that they flow into the main joint.

[0015] Preferably, the front and back of the confluence piece are both flat, and the two sides of the confluence piece are both arc surfaces, and the drainage hole and the pipe socket are respectively arranged at the center of the arcs on both sides. The flat surface is to make it easier for medical staff to grasp and facilitate the docking of the confluence piece with the inner cover. The arc surface is to reduce the volume of the confluence piece and has a better touch feel.

[0016] Preferably, the front and back sides of the confluence piece are both provided with anti-skid pieces, and the anti-skid pieces are made of elastic rubber material. The anti-skid pieces can increase friction, making it easier for medical staff to hold the confluence piece firmly.

[0017] Preferably, a gasket is provided on the inner groove surface of the outer cover, the gasket is made of elastic silicone material, and the gasket is tightly fitted with the outer end surface of the inner cover. The gasket improves the sealing between the outer cover and the inner cover to prevent stoma exudate from leaking from the stoma bag opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] Example 1

[0031] like Figures 1 to 7 The stoma bag accessory for drainage of effusion shown includes an inner cover 1 and an outer cover 3. The inner groove surface of the inner cover 1 is provided with a drainage hole 13 and a tube socket 14. Stoma exudate in the stoma bag cavity flows into the drainage hole 13. The stoma tube 41 extending from the patient's body is placed in the stoma bag cavity and connected to the tube socket 14. The drainage fluid in the stoma tube 41 flows into the tube socket 14. The inner circumference of the outer cover 3 is threadedly connected to the outer circumference of the inner cover 1. The stoma bag mouth 4 can be sealed and clamped between the outer cover 3 and the inner cover 1, so that the inner cover 1 seals the stoma bag cavity. The outer end surface of the inner cover 1 is connected to a confluence piece 2. The confluence piece 2 is provided with a main joint 23. The drainage hole 13 and the tube socket 14 are respectively connected to the main joint 23. Stoma exudate in the drainage hole 13 and drainage fluid in the tube socket 14 converge in the main joint 23. The medical staff puts the fistula tube 41 through the opening of the bottom plate of the stoma bag into the stoma bag cavity, and then connects the tube head of the fistula tube 41 to the tube plug 14. When the accumulated fluid is drained, the stoma exudate in the stoma bag cavity and the drainage fluid in the fistula tube 41 are gathered in the main joint 23, and are collected into the drainage bag cavity through the drainage bag catheter 42. The medical staff does not need to actively discharge the stoma exudate in the stoma bag cavity, which reduces the workload of the medical staff.

[0032] The outer cover 3 and the inner cover 1 are connected by threads and clamp the ostomy bag opening 4, which has good firmness and airtightness, making it difficult for ostomy exudate to leak from the ostomy bag opening 4, and is easy to assemble.

[0033] Among them, the outer end face of the outer cover 3 is provided with a through opening 30, the inner diameter of the through opening 30 is larger than the outer diameter of the confluence piece 2, so that the confluence piece 2 is arranged in the through opening 30, the inner diameter of the through opening 30 is smaller than the outer diameter of the inner cover 1, and the outer wall of the through opening 30 limits the outer cover 3 to the outer end face of the inner cover 1.

[0034] refer to Figure 2 and Figure 3 The tube socket 14 is provided with an internal thread, so that the tube socket 14 can be threadedly connected with the tube head of the fistula tube 41 with an external thread, and the tube socket 14 adopts a standard Luer connector. The standard Luer connector can clamp the tube wall of the fistula tube 41, and the firmness and airtightness between the tube socket 14 and the tube head of the fistula tube 41 are better, preventing the fistula tube 41 from being accidentally disconnected, resulting in a large amount of fluid in the ostomy bag cavity.

[0035] refer to Figures 1 to 3 The inner cover 1 is detachably connected to the confluence piece 2. The outer end surface of the inner cover 1 is provided with a bag joint 11 and a tube joint 12. The bag joint 11 is connected to the drainage hole 13, and the tube joint 12 is connected to the tube socket 14. The confluence piece 2 is provided with a bag interface 21 and a tube interface 22 on the surface connecting with the inner cover 1. The bag joint 11 is clamped in the bag interface 21, and the tube joint 12 is clamped in the tube interface 22. After the confluence piece 2 is removed, the bag joint 11 and the tube joint 12 are exposed, and medical staff can connect two different drainage bag catheters 42 to the bag joint 11 and the tube joint 12 respectively, so that the stoma exudate and the drainage fluid can be collected separately.

[0036] refer to Figure 3 and Figure 5 The outer circumference of the bag joint 11 and the outer circumference of the tube joint 12 are both provided with a limiter 16, and the outer diameter of the limiter 16 is larger than the inner diameter of the bag interface 21 and the inner diameter of the tube interface 22. When the confluence piece 2 is inserted until it touches the limiter 16, a gap is left in the confluence piece 2 at the end of the bag joint 11 and the end of the tube joint 12. The stoma exudate in the bag joint 11 and the drainage fluid in the tube joint 12 can flow into the main joint 23 through the gap. The limiter 16 limits the bag joint 11 and the tube joint 12 respectively, so that a large enough gap is left in the confluence piece 2 for the stoma exudate and the drainage fluid to converge, and ensure that they flow into the main joint 23.

[0037] refer to Figure 7 The front and back of the confluence piece 2 are both flat, and the two sides of the confluence piece 2 are both arc surfaces. The drainage hole 13 and the tube socket 14 are respectively arranged at the center of the arcs on both sides. The flat surface is for the medical staff to easily grasp and facilitate the docking of the confluence piece 2 and the inner cover 1. The arc surface is for reducing the volume of the confluence piece 2 and providing a better touch feel.
