[0032] In addition, the term "plurality" shall mean two or more.
[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0034] The utility model provides a waste liquid bag for CRRT equipment, such as Figure 1 As shown, it includes a waste liquid bag body 1 and a liquid receiving pipe 2. The waste liquid bag body 1 is provided with a liquid outlet 11, and the liquid outlet 11 is provided with a cover body 12 detachably connected thereto. The cover body 12 is provided with a through hole, and the discharge pipe of the CRRT equipment can be connected to the interior of the waste liquid bag body 1 through the through hole.
[0035] When the waste liquid bag is used in conjunction with a CRRT device, the waste liquid in the CRRT device enters the waste liquid belt body through the drain pipe for collection. After use, the medical staff can separate the cover body 12 from the liquid outlet 11, lift the waste liquid bag body 1, and quickly discharge the waste liquid in it through the liquid outlet 11, thereby reducing waiting time and effectively improving the work efficiency of the medical staff. Due to the detachable connection between the cover body 12 and the liquid outlet 11, it can be ensured that the waste liquid bag remains in a closed state during use, thereby reducing the risk of contamination. This design has a simple structure, low material cost, and is easy to manufacture, thereby reducing the overall cost of the waste liquid bag.
[0036] In some embodiments, the CRRT device used by the waste liquid bag is specifically a Fresenius brand CRRT device. In actual applications, it is found that the drainage pipe of the brand CRRT device is too short to be inserted into the improved waste liquid bag. In order to overcome this problem, a liquid receiving pipe 2 is further provided for the waste liquid bag. Figure 1 As shown, one end of the liquid receiving tube 2 extends into the waste liquid bag body 1 through the through hole on the cover body 12 to communicate with the interior thereof, and the other end is connected to the liquid receiving tube 2 and the discharge pipe of the CRRT device through the Luer connector 22. By adding the liquid receiving tube 2, the insufficient length of the discharge pipe can be compensated to ensure that the waste liquid can smoothly enter the waste liquid bag body 1. Using the Luer connector 22 as the connection method between the liquid receiving tube 2 and the discharge pipe of the CRRT device can provide a stable and reliable connection, ensure that there is no leakage during the transmission of the waste liquid, thereby improving the safety of the medical process. Through the liquid receiving tube 2 and the Luer connector 22, this waste liquid bag can be compatible with CRRT devices of different brands and models, improving its applicability in different medical environments.
[0037] Furthermore, a limiting ring 21 is provided at the end of the liquid receiving tube 2 extending into the waste liquid bag body 1, and the outer diameter of the limiting ring 21 is larger than the inner diameter of the through hole, and smaller than the inner diameter of the liquid outlet 11. The design of the limiting ring 21 can prevent the liquid receiving tube 2 from slipping during use. In some embodiments, the limiting ring 21 is made of rubber. Since the outer diameter of the limiting ring 21 is larger than the inner diameter of the through hole, it can fit tightly on the edge of the through hole, thereby forming a reliable seal to prevent waste liquid from leaking through the through hole. By increasing the stability and reliability of the connection, the design of the limiting ring 21 helps to improve the safety of the medical process and reduce the risk of accidents caused by loose connections.
[0038] In the prior art, due to the small design of the drainage port at the bottom of the waste liquid bag, the drainage speed is slow, and medical staff need to wait for 3-5 minutes to empty the waste liquid in the bag. In order to overcome this defect, further, such as Figure 1As shown, the liquid outlet 11 of the waste liquid bag is arranged at the upper left or upper right part of the waste liquid bag body 1, and a mounting hole 13 for mounting a handle ring 14 is arranged at the middle position of the upper part of the waste liquid bag. The handle ring 14 is fixedly mounted in the mounting hole 13, and the handle ring 14 has a wave edge structure to prevent hand strangulation. The liquid outlet 11 is arranged at the upper left or upper right part of the waste liquid bag body 1. This design enables medical staff to hold and control the waste liquid bag more conveniently when pouring waste liquid, reducing the difficulty and fatigue of operation; a mounting hole 13 is arranged at the middle position of the upper part of the waste liquid bag for mounting the handle ring 14. The handle ring 14 is fixedly mounted in the mounting hole 13, providing a stable gripping point, which is convenient for medical staff to lift and move the waste liquid bag; the handle ring 14 has a wave edge structure to prevent hand strangulation, which can reduce the pressure and discomfort on the hand when lifting and gripping, and improve the comfort of use. In general, such improvements help to reduce the workload of medical staff and improve work efficiency and safety.
[0039] Furthermore, the capacity of the waste liquid bag body 1 is 10L, and this capacity design can meet the needs of most medical applications and ensure sufficient waste liquid storage space; Figure 1 As shown, the waste liquid bag body 1 is provided with a scale line 15 for measuring the volume of the liquid in the bag, so that medical staff can easily monitor the accumulation of waste liquid and judge whether the waste liquid bag needs to be replaced or emptied; the waste liquid bag body 1 is specifically made of translucent plastic material, which allows medical staff to clearly see the waste liquid in the bag, which is convenient for monitoring and management. More preferably, a transparent material can be used to help observe the color, texture and other characteristics of the waste liquid.
[0040] In some embodiments, the cover 12 is threadedly connected to the liquid outlet 11. Through the threaded connection, the cover 12 can be quickly and conveniently connected to or removed from the liquid outlet 11. When operating, medical staff only need to rotate the cover 12 to tightly close or open the liquid outlet 11, which simplifies the operation process. Compared with other connection methods, the threaded connection has lower cost and higher reliability. This helps to reduce the overall cost of the waste liquid bag and improve its economy.
[0041] In the prior art, the CRRT device of the Fresenius brand has four hooks 4 arranged at intervals, and four hanging holes are arranged at intervals on the upper part of the waste liquid bag. The waste liquid bag can be hung stably through the one-to-one matching of the hanging holes and the hooks 4, so that the CRRT device can weigh the weight of the waste liquid in the waste liquid bag. The waste liquid bag provided by the utility model can also be stably hung on the hook 4 of the CRRT device in a similar manner, so that another connection method is also provided: such as Figure 2As shown, the waste liquid bag also includes a hanger 3, which can be stably hung on four hooks 4 of the CRRT device, and the hanger 3 is fixed to the handle ring 14 of the waste liquid bag body 1 by binding. In this way, the waste liquid bag can be more stably connected to the CRRT device, improving the stability and safety of the operation.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
