Technical Field

[0001] This utility model relates to the field of drainage fluid collection technology, specifically an integrated small-capacity wound drainage fluid collection bag. Background Technology

[0002] Wound drainage fluid collection bags, often simply referred to as drainage bags, are an important medical device. Drainage bags typically consist of a protective cap, drainage tube, thin film bag body, check valve, drain valve, hook or sling, etc. These parts work together to ensure that the drainage fluid can be collected smoothly and safely.

[0003] In clinical practice, patients with drainage tubes placed during surgery often experience increased wound infection risk and increased frequency of dressing changes and medicated dressing replacements after the tubes are removed. Furthermore, the wet gauze cannot accurately measure the exudate. Therefore, in order to reduce the risk of infection, ensure accurate measurement, and reduce the workload of clinical nurses and doctors, there is a need for an integrated small-capacity wound drainage collection bag that can solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated small-capacity wound drainage fluid collection bag, which has the advantages of being an integrated drainage fluid collection bag and easy to carry, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: an integrated small-capacity wound drainage fluid collection bag, including a modified ostomy bag. The inner wall of the modified ostomy bag is connected to a transparent isolation bag. The outer wall of the transparent isolation bag has an adhesive bottom bag. The outer wall of the transparent isolation bag is connected to a medical tubing. The inner wall of the medical tubing is connected to an elastic spring. The outer wall of the elastic spring is connected to a valve head. The inner wall of the medical tubing has a through hole. The outer wall of the modified ostomy bag is connected to a connector. The inner wall of the connector is fitted with a one-way anti-backflow valve. The outer wall of the connector is connected to a drainage tube. The bottom of the drainage tube is connected to a small-capacity collection bag. The outer wall of the small-capacity collection bag is connected to a hanging ear. The inner wall of the small-capacity collection bag is fitted with a second one-way anti-backflow valve. The bottom of the small-capacity collection bag is connected to a collection bag valve.

[0006] As a preferred embodiment of this utility model, the transparent isolation bag is disposed at the center of the modified ostomy bag, and the inner cavity of the transparent isolation bag is hollow.

[0007] As a preferred embodiment of this utility model, the inner cavity of the through hole is connected to the inner cavity of the transparent isolation bag, and the opening of the through hole faces the connector.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This integrated small-capacity wound drainage fluid collection bag is designed to collect small-capacity wound drainage fluid. In clinical practice, patients often have drainage tubes placed during surgery. After the drainage tubes are removed, the wound exudate continuously soaks the dressing, which not only increases the risk of wound infection but also increases the frequency of dressing and dressing changes for clinicians. Furthermore, the soaked gauze cannot accurately measure the exudate. Therefore, in order to reduce the probability of infection and ensure accurate measurement, thereby reducing the workload of clinical nurses and doctors, this integrated small-capacity wound drainage fluid collection bag is designed based on the Miles postoperative ostomy bag and Comvit anti-retrograde drainage.

[0013] 2. This integrated small-capacity wound drainage fluid collection bag, through the design of an improved ostomy bag, transparent isolation bag, drainage tube, and small-capacity collection bag, reduces bacterial contamination caused by changing drainage bags. The small capacity of 100-300mL is more portable than traditional drainage bags with a capacity of 1500mL or more, and the loop can be hung on the button of the patient's gown or put into a pocket due to its small capacity.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 An integrated small-capacity wound drainage fluid collection bag includes a modified ostomy bag 1, with a transparent isolation bag 2 connected to the inner wall of the modified ostomy bag 1. The outer wall of the transparent isolation bag 2 has an adhesive bottom bag 3. A medical tubing 4 is connected to the outer wall of the transparent isolation bag 2. An elastic spring 5 is connected to the inner wall of the medical tubing 4. A valve head 6 is connected to the outer wall of the elastic spring 5. A through hole 7 is opened in the inner wall of the medical tubing 4. A connector 8 is connected to the outer wall of the modified ostomy bag 1. A one-way anti-backflow valve 9 is fitted onto the inner wall of the connector 8. A drainage tube 10 is connected to the outer wall of the connector 8. A small-capacity collection bag 11 is connected to the bottom of the drainage tube 10. The outer wall of the device is connected to a hanging ear 12. The inner wall of the small-capacity collection bag 11 is fitted with a one-way anti-backflow valve 2 13. The bottom of the small-capacity collection bag 11 is connected to a collection bag valve 14. Through the cooperation of the one-way anti-backflow valve 1 9, the one-way anti-backflow valve 2 13 and the elastic spring 5 and valve head 6 on the device, the one-way anti-backflow valve 1 9 and the one-way anti-backflow valve 2 13 on the device have the same structure as the elastic spring 5 and valve head 6, the difference being that they are different in size. They are all one-way valves that can prevent the drainage fluid from flowing back. The elastic spring 5 and valve head 6 are made of silicone tubing, so that the valve can be prevented from being blocked by hand.

[0022] In a preferred embodiment, a transparent isolation bag 2 is disposed at the center of the modified ostomy bag 1, and the inner cavity of the transparent isolation bag 2 is hollow. By disposing the transparent isolation bag 2 at the center of the modified ostomy bag 1, the modified ostomy bag 1 covers the human skin. The transparent isolation bag 2 is aligned with the wound, and the transparent isolation bag 2 and the modified ostomy bag 1 are connected at the adhesive bottom bag 3, so that the transparent isolation bag 2 adheres to the skin, thereby collecting the fluid flowing out of the wound in the inner cavity of the transparent isolation bag 2.

[0023] In a preferred embodiment, the inner cavity of the through hole 7 is connected to the inner cavity of the transparent isolation bag 2, and the opening of the through hole 7 faces the connector 8. By connecting the inner cavity of the through hole 7 on the device to the inner cavity of the transparent isolation bag 2, the through hole 7 on the device is located on the outer wall of the transparent isolation bag 2. The liquid in the inner cavity of the transparent isolation bag 2 is guided into the inner cavity of the modified ostomy bag 1 through the through hole 7, so that the transparent isolation bag 2 on the device introduces the liquid into the inner cavity of the modified ostomy bag 1, and then the modified ostomy bag 1 is used to temporarily store the liquid.

[0024] In a preferred embodiment, the outer wall of the valve head 6 is adapted to the inner wall of the medical hose 4, and the valve head 6 is disposed in the inner cavity of the medical hose 4. By adapting the outer wall of the valve head 6 to the inner wall of the medical hose 4, the elastic spring 5 on the device is connected to the outer wall of the medical hose 4 and the outer wall of the valve head 6. The elastic spring 5 pushes the valve head 6 to press against the inner wall of the other side of the medical hose 4, thereby blocking the valve head 6 in the inner cavity of the medical hose 4.

[0025] In a preferred embodiment, the drainage tube 10 is connected to the inner cavity of the small-capacity collection bag 11, and a one-way anti-backflow valve 13 is provided at the connection point between the drainage tube 10 and the small-capacity collection bag 11. By connecting the drainage tube 10 and the inner cavity of the small-capacity collection bag 11, when the modified ostomy bag 1 on the device outputs liquid to the drainage tube 10 through the connector 8, the liquid flows through the inner cavity of the drainage tube 10 and converges into the inner cavity of the small-capacity collection bag 11, thereby allowing the liquid to finally enter the inner cavity of the small-capacity collection bag 11.

[0026] In a preferred embodiment, the collection bag valve 14 is located on the other side of the hanging ear 12, and the inner cavity of the collection bag valve 14 is connected to the inner cavity of the small-capacity collection bag 11. By having the collection bag valve 14 located on the other side of the hanging ear 12, the small-capacity collection bag 11 can be hung on the button of the patient's gown using the hanging ear 12, or it can be put into a pocket due to its small capacity. The collection bag valve 14 is used to open and close the small-capacity collection bag 11 at the bottom, so that the small-capacity collection bag 11 can be hung and the flow can be released. The collection bag 11 is provided with a scale, and the unit of the scale is ml.

[0027] In a preferred embodiment, the inner cavity of the small-capacity collection bag 11 on the device is 100ml-300ml.

[0028] The working principle involves collecting small-capacity wound drainage fluid through an integrated device. In clinical practice, patients often have drainage tubes placed during surgery. After the drainage tubes are removed, the wound exudate continuously soaks the dressing, which not only increases the risk of wound infection but also increases the frequency of dressing and dressing changes for clinicians. Furthermore, the soaked gauze cannot accurately measure the exudate. Therefore, to reduce the probability of infection and ensure accurate measurement, thereby reducing the workload of clinical nurses and doctors, the design of the Miles postoperative ostomy bag and Comvit anti-retrograde drainage bag is integrated into an integrated small-capacity wound drainage fluid collection bag. The improved design of the integrated ostomy bag 1, transparent isolation bag 2, drainage tube 10, and small-capacity collection bag 11 reduces bacterial contamination caused by changing drainage bags. The small capacity of 100-300mL is more portable than the traditional drainage bags with a capacity of 1500mL or more, and the loop 12 can be hung on the button of the patient's gown or put into a pocket due to its small capacity.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
