Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a drainage device capable of collecting postoperative exudate. Background Art

[0002] After abdominal surgery, a drainage tube is usually placed in the patient's body. Its main function is to drain fluid and other substances in the abdominal cavity to the outside of the body. By observing these drainage fluids, doctors can determine whether the patient has postoperative intracavitary bleeding or fluid accumulation, thereby monitoring the condition, measuring the amount, preventing postoperative infection, and promoting wound healing. However, during the actual drainage process, some patients' body fluids do not flow out completely through the lumen of the drainage tube, but may seep out along the gap between the drainage tube and the surface incision and flow to the skin surface. This situation is particularly obvious when a large amount of drainage fluid seeps out. It will not only contaminate wound dressings and clothing, but also interfere with the accurate measurement of drainage volume, increase the discomfort of patients with frequent dressing changes, and increase the workload of medical staff. Utility Model Content

[0003] In order to solve all or part of the problems of the above-mentioned prior art, the utility model provides a drainage device that can collect postoperative exudate. Through the hollow liquid collection chamber formed between the collecting part and the bag body, and the limiting component in the pipe socket, it ensures that the postoperative exudate can be collected quickly and effectively, reducing the risk of postoperative infection.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A drainage device capable of collecting postoperative exudate comprises a drainage line and a collection assembly, wherein the collection assembly is mounted on the drainage line, the collection assembly comprises a bag body and a collection portion, the collection portion comprises a connecting seat connected to the bag body, a hollow liquid collection chamber is formed inside the connecting seat, and the liquid collection chamber is communicated with the interior of the bag body; one side of the connecting seat is provided with an opening that fits tightly with the patient's incision, and the other side is provided with a pipe jack, a limiting component is provided in the pipe jack, the drainage line is introduced from the incision, passes through the liquid collection chamber, and is led out at the limiting component of the pipe jack. The utility model ensures that postoperative exudate can be collected quickly and effectively through the design of the collection portion, reducing the risk of postoperative infection; the limiting component provided in the pipe jack effectively fixes the drainage line, prevents the drainage line from falling off or shifting due to patient activity or other external forces, and ensures the continuity and safety of drainage.

[0006] The limiting component is an elastic sealing sleeve embedded in the pipe jack and securely connected to the drainage tubing. This provides a better seal, ensuring the closed and sterile environment of the fluid collection chamber. The elastic sealing sleeve also absorbs and cushions movement of the drainage tubing caused by patient movement or other external forces, reducing the risk of accidental dislodgment of the drainage tubing.

[0007] The retaining member comprises two stretchable members integral with the connector. These members are positioned within the pipe jack and connected to each other via an elastic connector, contracting toward the center of the jack. A sealing ring is positioned between the two members, tightly fitting the outer wall of the drainage tubing. This design accommodates drainage tubing of varying diameters. The synergistic effect of the stretchable members and the elastic connector provides a more secure fixation for the drainage tubing. Furthermore, the tight fit of the sealing ring enhances leak-proofing and ensures the closed and sterile state of the drainage system.

[0008] The collection unit also includes a mounting assembly, located on the side of the connector that contacts the patient's incision. The mounting assembly comprises a seal and an adhesive member positioned around the seal. The seal is designed to adhere tightly to the patient's skin, ensuring a tight seal between the collection unit and the patient's body, effectively preventing leakage of exudate and reducing the risk of infection. The adhesive member ensures that the collection unit is securely attached to the patient, maintaining stability even during movement, minimizing discomfort or reduced collection efficiency due to displacement.

[0009] The bag interior includes a connected collection area and retention area. The collection portion is located in the collection area, with a backflow prevention structure located between the two areas. The retention area is also marked with scale lines. The backflow prevention structure effectively prevents exudate from flowing back from the retention area into the collection area or into the patient's body, reducing the risk of infection and patient discomfort. This allows medical staff to intuitively monitor the amount of collected exudate, which is crucial for patient treatment records and follow-up care.

[0010] The anti-backflow structure is a long strip extending to either side of the bag. The strips are bonded together using heat pressing, leaving a liquid seepage channel in the middle of the bag. This ensures that the liquid flows in a single direction, reducing the possibility of backflow. The liquid seepage channel allows for more precise control of the liquid's flow, ensuring smooth flow into the collection area.

[0011] A plurality of hot-pressing point structures for preventing the backflow of the seepage liquid are arranged above the seepage channel. These structures effectively physically prevent the backflow of the seepage liquid, thereby enhancing the anti-backflow effect.

[0012] The liquid collection chamber is provided with a plurality of through-holes around its periphery, communicating with the bag body through the through-holes. An annular adsorbent is also provided within the liquid collection chamber, the inner ring of which is sleeved around the periphery of the drainage pipeline, and the outer ring of which is connected to the four edges of the liquid collection chamber. The through-hole design allows for rapid introduction of exudate from the incision and uniform dispersion into the liquid collection chamber, thus avoiding excessive localized accumulation of fluid. The annular adsorbent provides a larger contact area, enhancing adsorption, helping to more effectively guide and collect exudate, and improving collection efficiency.

[0013] The bottom of the bag body is also connected to a drainage pipe, which is provided with a drainage valve. Medical staff can open or close the drainage valve at any time as needed to control the discharge of exudate.

[0014] The device further comprises a drainage bag, wherein one end of the drainage pipe is connected to the source of the disease in the human body, and the other end passes through the fluid collection chamber and the pipe insertion hole and is connected to the drainage bag, thereby forming an unobstructed drainage path so that the accumulated fluid in the body can flow smoothly from the source of the disease to the drainage bag.

[0015] The utility model has at least the following beneficial effects:

[0016] 1) Through the carefully designed collection part and bag structure, the drainage device can quickly and effectively collect postoperative exudate, reducing the risk of postoperative infection. The limiting components set in the pipe socket, such as the combination of an elastic sealing sleeve or a stretching member and a sealing ring, provide a stable fixation method to prevent the drainage line from falling off or shifting due to patient movement or other external forces, thereby ensuring the continuity and safety of the drainage process. The hollow liquid collection chamber and the annular adsorption member can quickly and effectively collect postoperative exudate, improving the collection efficiency. The installation component of the collection part fits tightly against the patient's skin, ensuring the seal between the collection part and the patient's body.

[0017] 2) The design of the anti-backflow structure and exudate channel ensures that the exudate flows in a single direction, effectively preventing the exudate from flowing back from the retention area to the collection area or the patient's body. At the same time, the hot pressure point structure design effectively blocks the backflow of exudate, enhancing the anti-backflow effect. The scale line design on the retention area allows medical staff to intuitively monitor the amount of collected exudate, which is helpful for patient treatment records and follow-up care. The design of the drain pipe and drain valve at the bottom of the bag allows medical staff to easily control the discharge of exudate, simplifying the operation process and improving the convenience of use.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] In the present utility model embodiment, combined with reference Figure 1 、 2 As shown, a drainage device for collecting postoperative exudate is provided, aiming to provide a device with a simple structure, easy operation and the ability to effectively collect exudate. The device mainly consists of a drainage pipeline 1 and a collecting assembly 2, wherein the collecting assembly 2 is fixedly mounted on the drainage pipeline 1. The collecting assembly 2 includes a bag body and a collecting portion 3 connected to the interior of the bag body. The collecting portion 3 further includes a connecting seat 301, which is specially designed with two sides. One side is provided with an opening, which is intended to fit tightly with the patient's surgical incision to ensure the smooth collection of exudate. A pipe socket 302 is provided on the other side, and a limiting component is installed in the socket to fix the drainage pipeline 1 and prevent it from accidentally falling off or shifting. A hollow liquid collection chamber is formed inside the connecting seat 301, which is connected to the interior of the bag body to ensure that postoperative exudate can be smoothly introduced into the bag body from the incision.

[0025] The periphery of the liquid collection chamber is designed with a plurality of through holes, which ensure the connectivity between the liquid collection chamber and the bag body. In order to further improve the collection efficiency, the liquid collection chamber can also be equipped with an annular adsorption member, the inner ring of the adsorption member surrounds and is sleeved on the periphery of the drainage pipeline 1, and the outer ring is tightly connected to the edge of the liquid collection chamber, forming a stable support structure, which effectively guides the exudate to flow smoothly into the bag body. In addition, the collecting part 3 also includes a mounting component, which is located on the side of the connecting seat 301 that contacts the patient's incision. The mounting component is composed of a sealing member 303 and an adhesive member 304 on its periphery. Such a structural design not only ensures the sealing between the drainage device and the patient's incision, but also enhances the overall stability. Through these carefully designed components, the present device can efficiently collect and transmit postoperative exudate, which helps to improve the quality and convenience of postoperative care.

[0026] In this embodiment, the limiting component is designed as an elastic sealing sleeve embedded in the pipe socket 302, and the sealing sleeve is firmly connected to the drainage pipe 1 by plugging. Such a design not only ensures the stability of the drainage pipe 1, but also provides a simple and quick installation method. In addition, in order to adapt to different clinical application scenarios, the limiting component can also adopt a variety of fixing methods. For example, the limiting component can also be designed as two stretching parts integrally formed with the connecting seat 301. These two stretching parts are located at the pipe socket 302 and are connected to each other by elastic connectors, and can shrink toward the center of the pipe socket 302. A sealing ring is specially provided between the two stretching parts. The sealing ring can fit tightly with the outer peripheral wall of the drainage pipe 1, thereby ensuring the sealing of the liquid during the transfer process. Such a design not only enhances the fixity and sealing of the device, but also provides a flexible installation method that can adapt to drainage pipes 1 of different diameters.

[0027] The interior of the bag is divided into two interconnected areas: a collection area 4 and a retention area 5. The collection part 3 is arranged in the collection area 4, and the retention area 5 is provided with scale lines so that medical staff can intuitively monitor the amount of exudate collected. In order to ensure that the exudate can flow in one direction and prevent backflow, an anti-backflow structure 6 is provided between the collection area 4 and the retention area 5. In this embodiment, this structure is designed in the shape of an elongated strip, with its two ends extending to the two side edges of the bag body, and the elongated parts are bonded together through a hot pressing process, and an exudate channel is deliberately left in the middle of the bag body. In other embodiments, the anti-backflow structure 6 can be designed and adjusted differently as needed. In order to further prevent the backflow of exudate, multiple hot pressing point structures 7 are arranged above the exudate channel. These structures effectively physically block the backflow of exudate. In addition, in order to facilitate the drainage operation, a drainage pipe is provided at the bottom of the bag body, and the pipe is equipped with a drainage valve 8, so that medical staff can easily control the discharge of exudate.

[0028] The device also includes a drainage bag connected to one end of drainage tubing 1. Its primary function is to collect fluid from a source of disease. The other end of drainage tubing 1 is directly connected to the source of disease. Fluid is directed through the patient's surgical incision, flows through the fluid collection chamber, and finally, is guided into the drainage bag by a stopper within tubing jack 302.

[0029] The postoperative exudate collection and drainage device provided by the present invention significantly improves the quality and convenience of postoperative care with its simple structure, easy operation, and efficient exudate collection. Through its carefully designed multiple components, the device achieves orderly collection and transmission of exudate while ensuring safety and reliability. The tight integration of the drainage line 1 and the collection assembly 2, as well as the innovative design of the connector 301, not only ensures a tight seal with the patient's surgical incision, but also enhances the stability of the device. The through-holes and adsorbents in the collection chamber further improve the collection efficiency, ensuring that exudate can flow smoothly into the bag. The ingenious design of the anti-backflow structure 6 effectively prevents the backflow of exudate, ensuring unidirectional flow. The configuration of the drain pipe and drain valve 8 provides medical staff with a convenient drainage operation method. In addition, the diverse design of the limit components enables the device to adapt to drainage lines 1 of different diameters, increasing the flexibility of clinical application. Overall, the design of this device fully considers the needs of postoperative patients and the convenience of operation of medical staff, and is a beneficial innovation in the field of postoperative care.

[0030] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
