Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a visual three-way protector. Background Technology

[0002] With the rapid development of critical care medicine, central venous catheters (CVCs) are increasingly widely used in clinical practice, especially in intensive care units (ICUs), where patients often require multiple three-way valve assemblies and catheter accesses to meet complex treatment needs. However, the problem of CVC-related bloodstream infections has also become prominent. These infections not only increase patient mortality but also pose a serious threat to medical safety. In actual use, contaminants such as oral secretions and feces can easily penetrate the dressing at the puncture site, significantly increasing the risk of microorganisms entering the catheter lumen through the catheter connector, leading to bacterial proliferation and infection within the catheter lumen. To reduce the risk of contamination, sterile drapes are now commonly used in clinical practice to wrap the catheter connector to prevent contamination by metabolic waste such as urine, feces, and blood.

[0003] However, the use of sterile treatment drapes has many limitations. First, the process of wrapping sterile treatment drapes is cumbersome, requiring additional time and effort from medical staff. Second, the effectiveness of sterile treatment drapes is only a few hours; once contaminated with metabolic waste or blood, they must be replaced immediately, further increasing the burden on nursing staff. Furthermore, each time medication is administered, medical staff must untie the tape wrapped around the sterile treatment drape, complete the procedure, and then re-tie it. This process is not only inefficient but may also lead to catheter loosening or other unexpected situations. More importantly, the opaque nature of sterile treatment drapes prevents medical staff from directly observing the condition of catheter connections, making it difficult to detect problems such as catheter loosening, leakage, or ruptured stopcocks in a timely manner, thus delaying the treatment of potential risks. Therefore, existing technologies have significant shortcomings in terms of protective effectiveness, ease of operation, and real-time monitoring capabilities.

[0004] In view of this, the applicant hereby submits this application after studying the existing technology. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Depend on Figures 1 to 4 As shown, this embodiment of the invention provides a visualized three-way valve protector, whose main structure includes a bottom cover 2, an upper cover 3, and a receiving cavity 4 formed by the two. The receiving cavity 4 is used to fix the three-way valve assembly and limit its various ends to ensure the stability and safety of the three-way valve assembly during medical operations.

[0026] The bottom cover 2 and the top cover 3 are hinged together by a bendable portion 5 to form a complete protector body 1. The bendable portion 5 is located on one side of the protector, and its thickness is uniform and less than that of the bottom cover 2 and the top cover 3, allowing the top cover 3 to be bent relative to the bottom cover 2 along the hinge axis. When the top cover 3 and the bottom cover 2 are closed, the bendable portion 5 can also seal one side of the hinge end, thereby enhancing the overall sealing performance of the protector.

[0027] Preferably, the bottom cover 2 and the top cover 3 are quickly connected by a snap-fit ​​mechanism. The snap-fit ​​includes a protrusion 6 on the inner side of the bottom cover 2 and a groove 7 on the inner side of the top cover 3. The contact surfaces of the protrusion 6 and the groove 7 are designed as arc-shaped transition surfaces, forming a smooth fit when they engage, ensuring a firm and reliable snap-fit ​​connection. After snapping, a gap remains between the end of the protrusion 6 and the bottom of the groove 7, ensuring that the top cover 3 and the bottom cover 2 fit together tightly. In particular, the snap-fit ​​and the second receiving groove 9 are arranged alternately and are located on the side away from the hinge end, avoiding any impact on the three-way valve assembly from the snap-fit ​​position, and also ensuring a better fit between the top cover 3 and the bottom cover 2 after snapping.

[0028] Preferably, the design of the receiving cavity 4 fully considers the structural characteristics of the three-way valve assembly and is divided into multiple functional areas. The first receiving groove 8 is adapted to the tube body of the first input end 15 of the three-way valve assembly. The inner wall of the first receiving groove 8 is annular and has protrusions to limit the tube body of the first input end 15 in the circumferential direction. The second receiving groove 9 is adapted to the tube body of the second input end 16 of the three-way valve assembly. Its inner wall is also annular and has protrusions to limit the tube body of the second input end 16 in the circumferential direction. The third receiving groove 10 is provided corresponding to the output end 17, similarly limiting the circumferential direction of the output tube body of the three-way valve assembly. The bottom groove 11 is provided on the bottom cover 2 and can limit the valve body 14 of the three-way valve assembly in the radial direction. Considering all the limiting aspects and the T-shaped structure of the three-way valve itself, the combined protector body 1 can limit the three-way valve from all sides, ensuring that it is stably fixed inside the protector after installation. It should be noted that the circular groove 12 is located on the lower surface of the upper cover 3, and its diameter is slightly larger than the maximum outer diameter of the valve handle 19 of the three-way valve assembly. Furthermore, after the protectors are combined, due to the limiting effect on the various pipes of the three-way valve, a gap is left between the bottom of the circular groove 12 and the top of the valve handle 19, allowing the valve handle 19 to move freely within the circular groove 12 without obstruction or contact, thus avoiding any impact on flow rate and valve opening and closing. This design not only achieves omnidirectional limiting of each part of the three-way valve assembly but also ensures the stability of the valve handle 19.

[0029] Furthermore, in a preferred embodiment, the first receiving groove 8, the second receiving groove 9, and the third receiving groove 10 are connected to the end side of the protector for connecting a flexible hose. The opening of each receiving groove extends onto the flexible hose to improve the overall protection coverage of the three-way valve and to a certain extent reduce the risk of the hose port loosening or breaking due to swinging. A sealing ring can also be provided at the groove opening to enhance the sealing effect, which will not be elaborated upon here.

[0030] Preferably, the protector body 1 has gripping handles 20 on both sides, which extend outward and are integrally formed with the protector body 1. The outer surface of the gripping handles 20 may have anti-slip texture to increase the friction when gripping with fingers and improve the ease of opening and closing. In actual use, medical staff can easily open or close the protector using the gripping handles 20 without the need for other tools.

[0031] The protector body 1 is made of polycarbonate material, which has a light transmittance of no less than 85% in the visible light band, meeting the transparency requirements of medical environments. Simultaneously, the polycarbonate material undergoes modification treatment to maintain shape stability under 121°C high-temperature steam sterilization and possesses long-term resistance to contaminants such as blood, urine, and feces. The transparent design allows medical personnel to directly observe the status of the three-way valve assembly, promptly detecting problems such as loosening, leakage, or rupture, thereby reducing the risk of catheter-related bloodstream infections.

[0032] The three-way valve group can be composed of one or more three-way valves. In this embodiment, the three-way valve group is composed of multiple three-way valves connected together. The first input end 15 of the first three-way valve is connected to the infusion tube, the second input ends 16 of the multiple three-way valves are connected to the syringe, adjacent three-way valves are connected by a connecting pipe 18, the connecting pipe 18 is housed in the connecting groove 13, and the output end 17 of the last three-way valve is used to connect to the patient's intravenous access.

[0033] During use, medical staff can observe the status of the three-way valve assembly at any time through the transparent protective body 1. For example, if leakage or loosening occurs in the three-way valve assembly, medical staff can directly observe the abnormality through the protective body 1 and take immediate action. Furthermore, because the protective body 1 is made of high-performance materials, it can withstand various disinfection methods, extending its service life. When replacement or maintenance of the three-way valve assembly is required, medical staff can quickly complete the operation by simply opening the protective body using the handle 20.

[0034] This application achieves the following effects through the above technical solution: First, the transparent design allows medical staff to directly observe the status of the three-way valve assembly, promptly detecting problems such as loosening, leakage, or rupture, thereby reducing the risk of catheter-related bloodstream infections. Second, the multi-directional limiting structure ensures the stability of the three-way valve assembly within the protector, preventing displacement or leakage due to external impacts and avoiding accidental activation of the valve handle 19. Third, the combination of the bendable part 5 and the snap-fit ​​structure simplifies the opening and closing operation of the protector, improving work efficiency. Finally, the use of high-performance materials not only enhances the durability of the protector but also enables it to adapt to various disinfection methods, ensuring safety and sterility.

[0035] In summary, this application provides a three-way protector with visualization function, convenient operation and excellent protective performance, which solves the defects of traditional sterile treatment towel wrapping method, such as cumbersome operation, easy contamination and inconvenience of observation, and is suitable for the protection needs of three-way valve groups in intensive care environment.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
