Description

Technical Field

[0001] The invention relates to the technical field of drainage bags, in particular to an exhaustable anti-reflux drainage bag. Background Art

[0002] The one-way valve used in the current clinical anti-reflux drainage bag has a narrow drainage outlet and is only suitable for the drainage of gas and liquid, but cannot drain residual tissue fragments. If residual tissue flows out, it will block the valve. The current clinical drainage bag does not have the function of automatic exhaust and is not suitable for patients who need to drain gas. The closed chest drainage bottle used in the clinic can drain gas, but it is large and heavy and easy to fall to the ground and spill. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an exhaust-resistant reflux drainage bag, which solves the problems that the drainage outlet is narrow, is only suitable for the drainage of gas and liquid, cannot drain residual tissue fragments, and the drainage bag has no automatic exhaust function.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an exhaustable anti-reflux drainage bag, comprising a liquid collecting bag, a main drainage tube is installed on the upper surface of the liquid collecting bag, a drain valve is installed on the lower surface of the liquid collecting bag, a flushing and injection tube is installed on the inner side of the interface of the main drainage tube, a transparent soft film is installed inside the inlet of the liquid collecting bag, and an exhaust hole is installed on one side of the outer wall of the liquid collecting bag.

[0005] As a preferred technical solution of the present invention, a first protective grid is installed on the outer side of the exhaust hole, a breathable film is installed on the inner wall of the exhaust hole, and a second protective grid is installed on the inner side of the exhaust hole.

[0006] As a preferred technical solution of the present invention, the pipe opening of the flushing and injection pipe is threadedly connected with a nut.

[0007] As a preferred technical solution of the present invention, a buckle is installed on the outer wall of the main drainage tube.

[0008] As a preferred technical solution of the present invention, the breathable film is made of breathable and waterproof material.

[0009] As a preferred technical solution of the present invention, the transparent soft film consists of two sheets, a front sheet and a back sheet.

[0010] As a preferred technical solution of the present invention, a drainage bag pulling rope is installed on the upper surface of the liquid collection bag.

[0011] Compared with the prior art, the present invention provides an exhaustable anti-reflux drainage bag having the following features:

[0012] Beneficial effects:

[0013] 1. This exhaustable anti-reflux drainage bag has a transparent soft film installed at the outlet of the main drainage tube inside the liquid collection bag. Compared with the ordinary one-way valve located in the tube cavity, the transparent soft film will not cause the effective drainage tube diameter to become smaller, and has a wider range of applications. It can not only perform gas-liquid drainage, but also is suitable for the drainage of residual tissue fragments, and there will be no situation where the valve is blocked by tissue fragments.

[0014] 2. This is an exhaust-proof anti-reflux drainage bag. The exhaust hole adopts a breathable film made of breathable and water-impermeable material and two inner and outer protective nets, which ensures that the drainage fluid will not flow out while the air can be exhausted. The protective net can prevent the breathable membrane from being damaged by external collision and the exhaust hole from being blocked by the tissue drained from the inside.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1

[0020] See also Figure 1-2 In this embodiment: an exhaustable anti-reflux drainage bag comprises a liquid collecting bag 3, a main drainage tube 1 is installed on the upper surface of the liquid collecting bag 3, a drain valve 4 is installed on the lower surface of the liquid collecting bag 3, a flushing and injection tube 5 is installed on the inner side of the interface of the main drainage tube 1, a transparent soft film 7 is installed inside the inlet of the liquid collecting bag 3, and an exhaust hole 8 is installed on one side of the outer wall of the liquid collecting bag 3;

[0021] In this embodiment, the main drainage tube 1 is used to drain the accumulated gas and fluid, and the accumulated fluid is drained into the fluid collecting bag 3, and the setting of the discharge valve 4 can release the liquid in the fluid collecting bag 3, by installing a transparent soft film 7 at the internal entrance of the fluid collecting bag 3. The film consists of two front and back pieces, the left and right sides are connected and closed, the upper end is connected to the outlet of the main drainage tube 1, and the lower end is open, so as to facilitate the outflow of wound accumulated fluid and residual tissue. After the accumulated fluid flows out through the transparent soft film 7, the film will be affected by the viscosity of the liquid to close the lower end opening, forming a one-way anti-backflow valve, and the liquid in the bag cannot flow back upward. The setting of the exhaust hole 8 ensures that the air can be exhausted without the drainage fluid flowing out.
