Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a urinary tract ostomy bag that is easy to install a drainage tube and also has anti-reflux properties. Background Technology

[0002] Urostomy treats various urinary tract diseases by altering the urination pathway. After surgery, a drainage tube is used to guide urine directly from the kidney to the bladder and then to the ostomy bag. Therefore, retrograde flow of excrement can lead to infection. Traditional ostomy bags are prone to reflux due to changes in body position, blockage, or pressure, which can cause infection or skin damage.

[0003] Drainage tubes play a crucial role in maintaining urinary tract patency, reducing anastomotic pressure, and promoting healing after surgery. While existing anti-reflux ostomy bags can prevent fluid backflow and facilitate measurement, the ease of installation of drainage tubes has not been given sufficient attention.

[0004] This solution proposes a novel urinary tract bag design that integrates a channel for easy installation of drainage tubes while optimizing the anti-reflux structure (to prevent retrograde infection). The aim is to simultaneously address the issues of postoperative drainage safety and the convenience of drainage tube placement, thereby reducing the risk of complications and improving nursing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a urinary tract bag that is easy to install drainage tubes and also has anti-reflux properties, in order to solve the problems of postoperative drainage safety and drainage tube placement convenience, thereby reducing the risk of complications and improving nursing efficiency.

[0006] To address the aforementioned problems, this utility model provides a urostomy bag that facilitates the installation of drainage tubes and also prevents reflux. It includes a first bag membrane, a second bag membrane, an anti-reflux membrane, and an anti-reflux assembly. The first bag membrane has an external through-hole. The anti-reflux membrane is located between the first and second bag membranes, forming an upper chamber with the first bag membrane, and a lower chamber between the first and second bag membranes. The anti-reflux membrane has an internal through-hole communicating with the upper chamber. The anti-reflux assembly includes a main channel and a secondary channel disposed between the second bag membrane and the anti-reflux membrane. The main channel and secondary channel have different widths and are funnel-shaped. The main channel and secondary channel connect the upper and lower chambers, serving to install and place drainage tubes and guide excrement.

[0007] The first layer of the bag film is the body-side bag film, and the second layer of the bag film is the non-body-side bag film. The first layer of the bag film and the second layer of the bag film are preferably connected by welding.

[0008] The funnel-shaped channels of different widths can be adapted to various sizes and models of drainage tubes, and facilitate the installation, placement and insertion of drainage tubes.

[0009] The funnel-shaped channel separates the upper and lower chambers into two relatively independent chambers, which helps to prevent backflow.

[0010] According to one embodiment of the present invention, the anti-backflow component includes a set of large arched structures and two sets of small arched structures disposed between the anti-backflow membrane and the second layer of bag membrane. The opening direction of the arched structures is facing the lower chamber. The small arched structures are disposed on both sides of the large arched structures. The small arched structures and the large arched structures form a main channel and a secondary channel with different widths.

[0011] According to one embodiment of the present invention, the large arch structure and the two sets of small arch structures are located in the upper middle part of the second layer of the bag membrane to ensure the usable volume of the lower chamber.

[0012] According to one embodiment of the present invention, the urostomy bag, which facilitates the installation of drainage tubes and also prevents reflux, further includes a discharge valve, which is connected to the lower chamber and used to discharge excrement.

[0013] According to one embodiment of the present invention, the width of the main channel is 25±3mm.

[0014] According to one embodiment of the present invention, the width of the secondary channel is 15±3mm.

[0015] According to one embodiment of the present invention, a body-side nonwoven fabric is provided on the outer side of the first layer of bag film.

[0016] According to one embodiment of the present invention, a base plate connector is connected to the outer side of the first layer of bag film, which is generally a ring-shaped plastic part used to fix it to the base plate.

[0017] The beneficial effects of this utility model are that, by setting up an anti-backflow membrane and an anti-backflow component, after the excrement enters the upper chamber, it is quickly drained into the lower chamber through the funnel-shaped channel in the anti-backflow component. Since the upper chamber and the lower chamber are relatively independent, the purpose of preventing the backflow of excrement is achieved, thereby reducing the risk of retrograde infection. In addition, this solution is provided with funnel-shaped dual channels of different widths, which can be adapted to various specifications and models of drainage tube diameters, and facilitates the installation and placement of drainage tubes.

[0022] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0023]

Example 1

[0024] A urinary tract stoma bag that is easy to install drainage tubes and also prevents reflux, such as Figure 1 It includes a first layer bag film 3, a second layer bag film 6, an anti-backflow membrane 5, an exhaust valve 4, and an anti-backflow assembly 11.

[0025] The first layer of bag film 3 is the body-side bag film, and the second layer of bag film 6 is the non-body-side bag film. The first layer of bag film 3 and the second layer of bag film 6 are preferably connected by welding.

[0026] The outer side of the first layer of bag film 3 is provided with body-side non-woven fabric 2 and chassis connector 1. The chassis connector 1 is generally a ring-shaped plastic part used to fix it to the chassis.

[0027] The first layer of the bag membrane 3 has an external through-hole 8. An anti-backflow membrane 5 is located between the first layer of the bag membrane 3 and the second layer of the bag membrane 6. The anti-backflow membrane 5 is welded to the first layer of the bag membrane 3, forming an upper chamber. Figure 3 The upper chamber is located at point A in the figure. The lower chamber is formed between the first layer of bag membrane 3 and the second layer of bag membrane 6. The upper chamber is located at point B in the figure. The channel connecting the upper and lower chambers is located between the anti-backflow membrane 5 and the second layer of bag membrane 6.

[0028] The discharge valve 4 is installed between the first layer bag membrane 3 and the second layer bag membrane 6, and is connected to the lower chamber for discharging excrement.

[0029] The anti-backflow membrane 5 is provided with an internal through hole 7 that communicates with the upper chamber.

[0030] The anti-backflow assembly 11 includes a set of large arched structures 111 and two sets of small arched structures 112 disposed between the second layer bag membrane 6 and the anti-backflow membrane 5. The arched structures are connected to the anti-backflow membrane 5 and the second layer bag membrane 6. In this embodiment, the small arched structures 112 are semi-arched. The openings of the arched structures all face the lower chamber. The small arched structures 112 are disposed on both sides of the large arched structures 111. The small arched structures 112 and the large arched structures 111 form a main channel 113 and a secondary channel 114 with different widths.

[0031] The streamlined design of the arched structure effectively reduces the resistance when excrement passes through, improving drainage efficiency.

[0032] Preferably, the large arched structure 111 and the two sets of small arched structures 112 are located in the upper middle part of the second layer of bag membrane 6 to ensure the usable volume of the lower chamber.

[0033] The main channel 113 and the secondary channel 114 have different widths and are funnel-shaped. The curved surface design of the funnel shape allows excrement to pass through better, and the vertical design reduces the risk of excrement flowing backward. The main channel 113 and the secondary channel 114 connect the upper chamber and the lower chamber, and serve to install and place drainage tubes and guide the flow of excrement.

[0034] The main channel 113 and the secondary channel 114 form a dual-channel drainage structure. Considering the patient's postoperative positional changes, one channel is used for installing and placing the drainage tube, while the other channel is used for drainage of excrement. The two channels are relatively independent. The structural design conforms to ergonomics, maintaining stable drainage even when the patient is bedridden or active, reducing the risk of postoperative complications.

[0035] In this embodiment, the width of the main channel 113 is 25±3mm, and the width of the secondary channel 114 is 15±3mm.

[0036] The funnel-shaped channels of different widths can be adapted to various sizes and models of drainage tubes, and facilitate the installation, placement and insertion of drainage tubes.

[0037] The funnel-shaped channel separates the upper and lower chambers into two relatively independent chambers, and the arched structure, together with the funnel-shaped channel, plays a role in preventing backflow.

[0038] This solution employs a three-layer membrane integrated and segmented welding process. The innovation of this structure lies in the internal through-holes on the middle anti-backflow membrane, which connect to the external through-holes of the first bag membrane. It is also fixedly connected to the second bag membrane through a set of large arches and two sets of small arches. An asymmetrical drainage channel structure is formed between adjacent welding areas. One channel is used to install and place the drainage tube, and the other channel is used for excrement diversion. For example, the main channel 113 is used to install and place the drainage tube, and the secondary channel 114 is used for excrement diversion. The arched structure forms an anti-backflow barrier between the second bag membrane and the anti-backflow membrane, allowing the excrement to first flow through the upper chamber between the first bag membrane and the anti-backflow membrane, and then enter the lower chamber through the funnel-shaped channel. The excrement flows smoothly out of the lower chamber through the discharge valve. The upper and lower chambers are relatively independent to prevent excrement backflow and reduce the risk of retrograde infection.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
