Description

Technical Field

[0001] This utility model relates to the field of drainage bag technology, and in particular to a three-dimensional drainage bag. Background Technology

[0002] A drainage bag is a transparent or semi-transparent plastic bag that is connected to the patient's body through a drainage tube. It is used to collect and drain fluids, such as wound exudate, effusion, blood, and urine, to prevent them from accumulating in the body. By observing the color, amount, and characteristics of the drainage fluid, medical staff can promptly assess changes in the patient's condition. Draining effusion can keep the wound dry, reduce the risk of infection, accelerate healing, and promptly remove abnormal fluid, reducing pressure on surrounding tissues and minimizing complications.

[0003] In current technology, the production of drainage bags requires the fabrication of a membrane, followed by high-frequency bag making of the PVC membrane, and finally ink printing to form text and scales. This process generates a large amount of scrap waste that needs to be recycled and processed, while also presenting ink pollution problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a three-dimensional drainage bag.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A three-dimensional drainage bag, comprising a drainage bag, characterized in that: the drainage bag comprises:

[0007] Bag body;

[0008] Two pipe interfaces are respectively located at the top and bottom of the bag body;

[0009] The two aforementioned pipe interfaces are integrally formed with the bag body using a blow molding process;

[0010] The surface of the bag is decorated with embossed text.

[0011] Preferably, both of the pipe interfaces include a short pipe and an installation port. The two short pipes are respectively located at the top and bottom of the bag body, and the installation port is located on one side of the short pipe and communicates with the inner cavity of the bag body.

[0012] Preferably, both the bag body and the short tube are integrally molded from PVC material.

[0013] Preferably, the bag body is formed by blow molding and has a three-dimensional cavity.

[0014] Preferably, the engraved text on the surface of the bag is a liquid level scale.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a blow molding process to integrally mold the bag structure, avoiding the leakage risks that may result from splicing multiple parts. This improves the sealing and reliability of the drainage bag. Simultaneously, the integral molding process simplifies the production process and reduces production costs. Two pipe interfaces are located at the top and bottom of the bag and are molded synchronously with the bag body, facilitating connection to the drainage pipes. Embossed text structures are pre-set on the inner wall of the blow molding mold cavity, allowing corresponding text markings to be directly formed on the bag surface during the blow molding process, eliminating the need for additional printing steps. This avoids generating a large amount of waste material, saving printing costs, and preventing ink contamination problems that may occur during printing. Furthermore, the embossed text is more durable than printed text, less prone to blurring or disappearing due to friction or cleaning, ensuring clear readability of the text markings throughout the entire lifespan of the drainage bag, facilitating accurate reading of relevant information by medical personnel.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 and Figure 2 A three-dimensional drainage bag includes a drainage bag 1, wherein the drainage bag 1 comprises:

[0022] The bag body 2 is manufactured using a blow molding process to achieve an integral, one-piece structure.

[0023] Two pipe interfaces 3 are respectively located at the top and bottom of the bag body 2. The pipe interfaces 3 have a flat design on both sides and are formed synchronously with the bag body 2.

[0024] The surface of the bag body 2 is provided with recessed text 4. By pre-setting the raised text structure on the inner wall of the blow molding mold cavity, the corresponding text mark is directly formed on the surface of the bag body 2 during the blow molding process, without the need for additional printing process.

[0025] When in use, this device employs a blow molding process to integrally form the bag body 2, avoiding the leakage risks that may result from splicing multiple parts. This improves the sealing and reliability of the drainage bag 1. Simultaneously, the integral molding process simplifies the production process and reduces production costs. Two pipe interfaces 3 are respectively located at the top and bottom of the bag body 2 and are formed synchronously with the bag body 2, facilitating connection to the drainage pipes. Embossed text structures are pre-set on the inner wall of the blow molding mold cavity, allowing corresponding text markings to be directly formed on the surface of the bag body 2 during the blow molding process, eliminating the need for additional printing steps. This avoids generating a large amount of waste material, saving printing costs, and also avoids ink contamination problems that may occur during printing. Furthermore, the embossed text 4 is more durable than printed text, less prone to blurring or disappearing due to friction or cleaning, ensuring clear readability of the text markings throughout the entire service life of the drainage bag 1, facilitating accurate reading of relevant information by medical personnel.

[0026] Furthermore, both of the aforementioned pipe interfaces 3 include a short pipe 5 and an installation port 6. The two short pipes 5 are respectively located at the top and bottom of the bag body 2. The installation port 6 is located on one side of the short pipe 5 and communicates with the inner cavity of the bag body 2. The design of both pipe interfaces 3 including a short pipe 5 and an installation port 6 provides a stable structure for connection with the bag body 2, while the installation port 6 facilitates quick insertion and removal of external drainage pipes, enabling more convenient pipe replacement and connection operations and improving work efficiency.

[0027] Furthermore, both the bag body 2 and the short tube 5 are integrally molded from PVC. PVC material has good flexibility, corrosion resistance, and transparency. The flexibility allows the drainage bag 1 to adapt to different usage scenarios and fit different parts of the body. The corrosion resistance ensures that the drainage bag 1 will not be corroded or damaged when in contact with various drainage fluids, thus extending the service life of the drainage bag 1. The transparency allows medical staff to directly observe the color, properties, and amount of drainage fluid inside the bag, which helps to detect changes in the patient's condition in a timely manner.

[0028] Furthermore, the bag body 2 is formed into a single three-dimensional cavity in one step during blow molding. This three-dimensional cavity has a compact structure, which can be adapted to fit with the leg support device and can also be assembled with the shoulder strap device. The compact structure of the bag body 2, formed into a single three-dimensional cavity in one step during blow molding, allows it to fit with the leg support device, making it convenient for patients to fix the drainage bag 1 to their legs while moving, without affecting their normal activities. At the same time, it can also be assembled with the shoulder strap device to meet different usage needs of patients. For example, patients can carry the drainage bag 1 with the shoulder strap device when sitting or standing, which improves the flexibility and convenience of using the drainage bag 1 and improves the patient's medical experience.

[0029] Furthermore, the engraved text 4 on the surface of the bag 2 is a liquid level scale. The engraved liquid level scale is more accurate and durable than the printed or pasted liquid level scale. Medical staff can accurately read the liquid level scale to understand the amount of drainage fluid discharged in a timely manner. Moreover, the engraved scale is not easily affected by external factors. Even if the drainage bag 1 has been used and cleaned many times, the scale is still clearly identifiable, ensuring the accuracy and reliability of the measurement.

[0030] Furthermore, the blow-molded bag 2 adopts a three-dimensional structural design, which gives the bag 2 a certain rigidity. The bag 2 can effectively resist deformation and avoid excessive shape changes, thereby ensuring the accuracy of the measurement results corresponding to the scale set on the bag 2. The blow-molded bag 2 adopts a three-dimensional structural design, which gives the bag 2 a certain rigidity, enabling it to effectively resist deformation and avoid excessive shape changes. In actual use, whether subjected to external pressure or due to the gravity of the internal drainage fluid, the bag 2 can maintain a relatively stable shape, thereby ensuring the accuracy of the measurement results corresponding to the scale set on the bag 2.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
