Abstract
Description
Technical Field
[0001] The utility model relates to the field of disposable medical supplies, in particular to a drainage bag. Background Art
[0002] The drainage bag currently used in clinical practice cannot be used to collect drainage fluid at the lower end of the drainage bag. When collecting drainage fluid for culture, doctors need to puncture the drainage bag or drainage tube with a syringe before collecting the drainage fluid.
[0003] The main defects of the existing operation method are: the punctured drainage bag needs to be replaced, which increases the workload of nurses and the cost of patients; after the drainage tube or drainage bag is punctured by the syringe, drainage fluid will leak out, which is easy to be contaminated and increases the chance of infection. Utility Model Content
[0004] The utility model aims at the above-mentioned problems, overcomes at least one disadvantage and provides a drainage bag.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A drainage bag, comprising:
[0007] Bag body;
[0008] A drainage tube, one end of which is connected to the upper end of the bag body;
[0009] The Y-shaped liquid discharge tube has three interfaces, namely, a first interface, a second interface and a third interface. The first interface is connected to the lower end of the bag body, the second interface is a waste discharge port, and the third interface is a spiral BD interface, and the third interface is used to connect a syringe;
[0010] A first cover cap, screwed onto the second interface;
[0011] The second cover cap is screwed on the third interface.
[0012] The drainage tube of the drainage bag of the present application is a Y-shaped drainage tube, and the second interface is the drainage port of a traditional drainage bag. By setting an additional third interface, it can be connected to a syringe, and drainage fluid can be extracted through the third interface. Compared with existing drainage bags, it can reduce the workload of medical staff, reduce the occurrence of infection, avoid frequent replacement of drainage bags, and reduce patient costs.
[0013] In one embodiment of the present invention, a sampling inner tube is further included, one end of the sampling inner tube extends into the bag body, and the other end extends into the Y-shaped drainage tube and is connected to the third interface.
[0014] The best area for sampling is the middle area. When the third interface extracts the drainage fluid, the drainage fluid in the bag can be directly extracted through the sampling inner tube. Compared with extracting the drainage fluid at the bottom, the sampling sample is better.
[0015] In one embodiment of the present invention, a convex portion is provided on the outer side wall of one end of the sampling inner tube extending into the bag body.
[0016] The convex portion is provided to facilitate adjustment of the position of the sampling inner tube in the bag body.
[0017] In one embodiment of the present invention, the protrusion is a buoyancy protrusion.
[0018] When there is a large amount of drainage fluid in the bag, the buoyancy convex portion can make the sampling inner tube have a larger buoyancy, so as to facilitate and better adjust the position of the sampling inner tube in the bag.
[0019] In one embodiment of the present invention, when the sampling inner tube is straightened, the end of the sampling inner tube extending into the bag body is located in the middle of the bag body or in an upper position of the middle.
[0020] In one embodiment of the utility model, a seal is installed on the end face of one end of the sampling inner tube extending into the bag body, and the seal has a sealing gap. When the air pressure inside the sampling inner tube becomes smaller, the liquid in the bag body can enter the sampling inner tube through the sealing gap.
[0021] In one embodiment of the present invention, the upper end of the bag body has a hanging belt.
[0022] In one embodiment of the present invention, a flow limiting clamp is disposed on the drainage tube.
[0023] In one embodiment of the present invention, the third interface is a separation membrane needle-free closed infusion connector.
[0024] The beneficial effects of the utility model are as follows: the drainage tube of the drainage bag of the present application is a Y-shaped drainage tube, the second interface is the drainage port of a traditional drainage bag, and by providing an additional third interface, it can be connected to a syringe, and drainage fluid can be extracted through the third interface. Compared with existing drainage bags, it can reduce the workload of medical staff, reduce the occurrence of infection, avoid frequent replacement of drainage bags, and reduce patient costs.

[0033] The utility model is described in detail below in conjunction with the accompanying drawings.
[0034] Example 1
[0035] like Figure 1 As shown, a drainage bag comprises:
[0036] Bag body 1;
[0037] A drainage tube 2, one end of which is connected to the upper end of the bag body 1;
[0038] The Y-shaped liquid discharge tube 3 has three interfaces, namely, a first interface 31, a second interface 32 and a third interface 33. The first interface 31 is connected to the lower end of the bag body 1, the second interface 32 is a waste discharge port, and the third interface 33 is a spiral BD interface, and the third interface 33 is used to connect a syringe;
[0039] A first cover cap 4 is screwed onto the second interface 32;
[0040] The second cover cap 5 is screwed onto the third interface 33 .
[0041] The drainage tube of the drainage bag of the present application is a Y-shaped drainage tube 3, and the second interface 32 is the drainage port of a traditional drainage bag. By setting an additional third interface 33 (the third interface 33 of this embodiment is a separation membrane needle-free closed infusion connector), it can be connected to a syringe, and drainage fluid can be extracted through the third interface 33. Compared with existing drainage bags, it can reduce the workload of medical staff, reduce the occurrence of infection, avoid frequent replacement of drainage bags, and reduce patient costs.
[0042] like Figure 1 As shown, in this embodiment, the upper end of the bag body 1 has a hanging belt 11. In actual use, a flow limiting clamp is provided on the drainage tube 2.
[0043] Example 2
[0044] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the drainage bag of this embodiment further includes a sampling inner tube 6, one end of the sampling inner tube 6 extends into the bag body 1, and the other end extends into the Y-shaped drainage tube 3 and is connected to the third interface 33.
[0045] The best sampling area is the middle area. When the third interface 33 extracts drainage fluid, the drainage fluid in the bag body 1 can be directly extracted through the sampling inner tube 6. Compared with extracting drainage fluid at the bottom, the sampling sample is better.
[0046] like Figure 2 As shown, in this embodiment, the outer wall of the end of the sampling inner tube 6 extending into the bag body 1 has a convex portion 61. The convex portion 61 is provided to facilitate adjustment of the position of the sampling inner tube 6 in the bag body 1.
[0047] Preferably, the convex portion 61 is a buoyancy convex portion 61. When there is more drainage fluid in the bag body 1, the buoyancy convex portion 61 can make the sampling inner tube 6 have greater buoyancy, so as to facilitate better adjustment of the position of the sampling inner tube 6 in the bag body 1.
[0048] like Figure 2 As shown, in this embodiment, when the sampling inner tube 6 is straightened, the end of the sampling inner tube 6 extending into the bag body 1 is located in the middle of the bag body 1 or in the upper middle position.
[0049] like Figure 3 As shown, in this embodiment, a sealing member 7 is installed on the end face of one end of the sampling inner tube 6 extending into the bag body 1. The sealing member 7 has a sealing gap 71. When the internal air pressure of the sampling inner tube 6 becomes smaller, the liquid in the bag body 1 can enter the sampling inner tube 6 through the sealing gap 71.
[0050] The above description is only a preferred embodiment of the present invention, and does not limit the patent protection scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the present invention.
