Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a drainage bag. Background Art

[0002] Negative pressure drainage is widely used to drain residual and exudate fluids in wounds of postoperative patients, which can promote tissue repair.

[0003] Currently available methods mainly include drainage through hard containers, which are inconvenient to drain, have high manufacturing costs, and high post-use processing costs. Summary of the invention

[0004] The utility model aims to provide a drainage bag which has a simple and reasonable structure and can use the soft drainage bag as a negative pressure drainage bag and can overcome the defects of the prior art.

[0005] In order to solve these problems in the prior art, the technical solution provided by the utility model is: a drainage bag, including a bag body and a liquid inlet tube, which can be placed in a hard negative pressure bottle, and the bag body liquid inlet tube is sleeved with a negative pressure bottle cap; a sealing gasket is placed above the bag body below the negative pressure bottle cap, and the axis of the liquid inlet tube passes through the center of the sealing gasket.

[0006] In a preferred implementation state, the liquid inlet pipe passes through the center of the sealing gasket without any gap.

[0007] In a preferred implementation state, the sealing gasket has pipe joints connected to the liquid inlet pipe at the top and bottom.

[0008] In a preferred implementation state, the negative pressure bottle cap can be screwed and sealed on a threaded opening on the negative pressure bottle.

[0009] All the above spatial orientations are described based on the product being in a normal upright state.

[0010] Compared with the solutions in the prior art, the advantages of the utility model are:

[0011] First, the structure is simple;

[0012] Second, the soft drainage bag can be used as a negative pressure drainage bag;

[0013] Thirdly, the hard negative pressure bottle that can be placed in the soft bag body can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The structures, proportions, sizes, etc. illustrated in this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by persons familiar with the technology. They are not used to limit the conditions under which the present invention can be implemented, and therefore have no substantial technical significance. Any structural modification, change in proportion or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical contents disclosed by the present invention.

[0015] Figure 1 It is a structural schematic diagram of an embodiment of the utility model;

[0016] The numbers in the figure indicate:

[0017] 1. Negative pressure bottle cap; 2. Sealing gasket; 3. Bag body. Implementation

[0018] The above scheme is further described below in conjunction with specific embodiments. It should be understood that these embodiments are used to illustrate the present invention and are not used to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional production. Example

[0019] like Figure 1 As shown, the utility model provides a drainage bag, including a bag body 3 and a liquid inlet tube. The soft bag body 3 can be placed in a hard negative pressure bottle, and the bag body 3 is sleeved with a negative pressure bottle cap 1; a sealing gasket 2 is arranged around the liquid inlet tube above the bag body 3 below the negative pressure bottle cap 1, and the liquid inlet tube passes through the center of the sealing gasket 2 and is bonded with glue without a gap.

[0020] When in actual use, the soft bag body 3 is folded and placed in a matching hard negative pressure bottle, the sealing gasket 2 is attached to the mouth of the hard negative pressure bottle, and the negative pressure bottle cap 1 that can rotate freely relative to the liquid inlet pipe is screwed and sealed with the mouth of the negative pressure bottle. The negative pressure bottle is evacuated using a negative pressure source, and the bag body 3 is in negative pressure before use. Example

[0021] like Figure 1 As shown, the utility model provides a drainage bag, including a bag body 3 and a liquid inlet tube. The soft drainage bag body 3 can be placed in a hard negative pressure bottle, and a negative pressure bottle cap 1 is sleeved on the liquid inlet tube of the bag body 3; a sealing gasket 2 is arranged above the bag body 3 below the negative pressure bottle cap 1, and the sealing gasket has pipe joints connected to the liquid inlet tube above and below.

[0022] When in actual use, the soft bag body 3 is folded into the matching hard negative pressure bottle, the sealing gasket 2 is attached to the mouth of the hard negative pressure bottle, the negative pressure bottle cap 1 that can rotate freely relative to the liquid inlet pipe is screwed and sealed with the mouth of the negative pressure bottle, and the negative pressure bottle is evacuated by a negative pressure source, and the bag body 3 is used when negative pressure is present. After the drainage is completed, the drainage cap at the bottom of the negative pressure bottle can be unscrewed, the drainage pipeline can be pulled out to drain the liquid, and then the bag body can be taken out and continued to be used or replaced with a new bag body for continued use.

[0023] The above is a detailed introduction to a drainage bag provided by the utility model. The principle and implementation method of the utility model are explained in this article. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. At the same time, for general technicians in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
