Description

Technical Field

[0001] This utility model relates to medical devices, specifically to a drainage device used after surgical procedures. Background Technology

[0002] Drainage devices are used in postoperative care to drain blood and fluid from the wound after surgery, helping to reduce the risk of infection, promote healing, and prevent infection and complications caused by fluid accumulation.

[0003] Changes in the color of surgical drainage can reflect the healing progress of the surgical site and potential complications. If the drainage is clear or light yellow, it is normal, indicating that the surgical site is draining waste normally during the healing process. If the drainage is pink or light red, this may be normal in the early postoperative period due to minor bleeding from the surgical site. If the drainage remains red for an extended period, prompt medical evaluation is necessary. If there are significant changes in the color or nature of the drainage, it is recommended to consult a doctor for further evaluation and treatment.

[0004] Existing drainage devices use catheters to drain fluid into a transparent bag, allowing doctors to observe the color of wound exudate as displayed on the bag. The drawback is that they cannot compare changes in drainage fluid at different postoperative time points, thus failing to provide doctors with accurate information on postoperative exudate changes and hindering their ability to prescribe medication based on the patient's condition.

[0005] In view of the above, this utility model is hereby applied for. Utility Model Content

[0006] This invention provides a novel surgical drainage device that solves the problem that existing drainage devices cannot compare and observe changes in drainage fluid at different postoperative time periods.

[0007] To solve the above problems, the present invention adopts the following technical solution: a novel surgical drainage device, including a drainage tube 2, a reservoir bag 3, and an infusion controller 4; the drainage tube 2 is connected to the reservoir bag 3; it also includes observation bags 31, which are equally spaced on the side of the reservoir bag 3, and the observation bags 31 and the reservoir bag 3 are formed by heat pressing two transparent plastic films into an integral structure; each observation bag 31 has an insertion hole 311 that communicates with the outside, and the drainage tube 2 is also connected to the insertion hole 311 on the observation bag through a needle.

[0008] Furthermore, the novel surgical drainage device of this utility model also has the following features: the insertion hole 311 contains a sealing body formed by a sealing flap 312, the sealing body is formed by radial slits 313 to form the sealing flap 312 structure, and the edge of the sealing flap 312 is connected to the bag body of the observation bag 31 to form an integral whole.

[0009] Furthermore, the novel surgical drainage device of this utility model also has the following features: the lower end of the drainage tube 2 is connected to the inlet 32 ​​on the reservoir bag 3; the middle section of the drainage tube 2 is connected to a branch tube 21, and an infusion controller 4 for opening or blocking the liquid in the branch tube 21 is installed on the branch tube 21; the end of the branch tube 21 is connected to a needle 5, and the needle 5 is inserted into the middle of the sealing valve 312 through the insertion hole 311.

[0010] Furthermore, the novel surgical drainage device of this utility model also has the following features: the drainage tube 2 is not directly connected to the reservoir bag 3, the end of the drainage tube 2 is connected to the needle 5, the needle 5 is inserted into the insertion hole 311 of a certain observation bag 31, and each observation bag 31 and the reservoir bag 3 are provided with a check valve 6 that allows liquid to flow into the reservoir bag 3 in one direction.

[0011] Furthermore, the novel surgical drainage device of this utility model also has the following features: a sealing head 314 is provided on the plastic strip connected to the side of the insertion hole 311, and the sealing head 314 cooperates with the insertion hole 311.

[0012] Advantages of this utility model: 1. Several transparent observation bags are set on the side of the drainage bag. Postoperative exudate is introduced into the observation bags at regular intervals to compare the color and blood content of the postoperative exudate.

[0013] 2. It allows doctors to accurately observe changes in drainage fluid and assess wound healing progress.

[0014] 3. Easy to operate; patients or caregivers can operate independently to direct wound exudate into the observation bag.

[0015] 4. Patients or caregivers should closely observe the color of the drainage fluid. If any abnormal changes are found in the drainage fluid (such as bloody or intestinal fluid), the doctor should be informed in a timely manner so that the doctor can handle the situation promptly and avoid delaying the condition.

[0016] 5. After the observation bag is full, the liquid will automatically flow into the storage bag, preventing the bag from overflowing or leaking.

[0017] 6. The storage bag and observation bag are made by heat pressing as one piece, which reduces costs. Attached Figure Description

[0020] The present invention will now be described in detail using the preferred embodiments. Example 1

[0021] like Figure 1-3 As shown, a novel surgical drainage device includes a drainage tube 2, a reservoir bag 3, and an infusion controller 4; it also includes observation bags 31, which are evenly spaced along the side of the reservoir bag 3. The observation bags 31 and the reservoir bag 3 are integrally formed by heat-pressing two transparent plastic films; each observation bag 31 has an insertion hole 311 communicating with the outside, and a sealing body formed by sealing flaps 312 is located inside the insertion hole 311. The sealing body is formed by radial slits 313 to create the sealing flap 312 structure, and the edge of the sealing flap 312 is integrally connected to the bag body of the observation bag 31. The sealing flap 312 structure facilitates the insertion of a needle 5 to infuse postoperative wound exudate into the observation bag 31. The upper end of the drainage tube 2 is connected to a drainage head 1, which is used to introduce postoperative wound exudate. The lower end of the drainage tube 2 is connected to an inlet 32 ​​on a storage bag 3. A branch tube 21 is connected to the middle section of the drainage tube 2. An infusion controller 4 for opening or closing the fluid in the branch tube 21 is installed on the branch tube 21. A needle 5 is connected to the end of the branch tube 21. The needle 5 is inserted into the middle of the sealing valve 312 through the insertion hole 311, so that the postoperative exudate can be collected into the observation bag. The needle 5 is made of steel or hard plastic for easy insertion. A sealing head 314 is attached to the plastic strip connected to the side of the insertion hole 311. The sealing head 314 cooperates with the insertion hole 311. After the observation bag 31 is filled with exudate, the needle 5 is pulled out and the sealing head 314 is used to seal it. Example 2

[0022] As shown in Figure 4, the difference between this embodiment and the first embodiment is that: no branch tube 21 is provided, the end of the drainage tube 2 is connected to the needle 5, the needle 5 is inserted into the insertion hole 311 of a certain observation bag 31, and a check valve 6 is provided between each observation bag 31 and the liquid storage bag 3 to allow the liquid to flow into the liquid storage bag 3 in one direction.

[0023] Postoperative exudate is drained through drainage tube 2. The needle 5 on drainage tube 2 is inserted into the first observation bag 31, which retains the exudate. Excess fluid is stored in the reservoir bag 3 through the inlet 32 ​​(Example 1) or the check valve 6 (Example 2). The patient or caregiver periodically changes the needle 5 to the adjacent observation bag 31. During the change, the infusion controller is turned off, and the side of the insertion hole is pressed with one hand while the insertion hole is sealed with the sealing head with the other hand. This allows the observation bag 31 to store wound exudate from different time periods. The doctor can judge the condition of the wound after surgery based on the color and blood content of the exudate. At the same time, it is convenient for the patient or caregiver to observe the color change of the drainage fluid at any time after surgery. If any abnormality is found, the doctor should be notified in time.
