Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular, relates to an intestinal fistula plug. BACKGROUND

[0002] Intestinal fistula is an abnormal channel between the intestinal tract and the skin, and its incidence after gastrointestinal surgery is between 0.8% and 2%, and the mortality rate is between 5% and 20%. The main causes of death are infection and malnutrition (1). Very few intestinal fistulas can heal on their own, and most of them need to be repaired by surgery again. However, considering the problems of intestinal adhesion, wound infection, malnutrition and other problems caused by the first surgery, the second surgery can only be performed on average 111 days after the first surgery (range 30-380 days) (2, 3).

[0003] Before the second surgery repair, wound and infection control is very important. Currently, there are some simple techniques and ostomy care equipment for wound control. Such as wound care cream and negative pressure suction device. Wound care cream is suitable for mild infection such as redness and exudation around the stoma (3, 4); negative pressure suction device is suitable for non-stoma wounds with less exudation (1). For wound infection caused by intestinal fistula, there is currently no effective treatment device and measure. Because the intestinal fistula exudes more (300-1500ml), it is easy to contaminate and corrode the wound. There are residues in the intestinal fluid, which are easy to block the suction tube, causing difficulty in negative pressure suction. If the wound exudes more or the suction tube is blocked, it will cause poor airtightness, etc., increasing the replacement frequency. And the traditional negative pressure suction device directly sucks the wound with a sponge, and the wound granulation tissue is corroded by the intestinal fluid, so the patient suffers a lot when replacing. SUMMARY

[0004] In order to solve the problems of the prior art, the present application provides an intestinal fistula plug. The technical solution is as follows:

[0005] On the one hand, an intestinal fistula plug is provided, comprising: a sponge plug and a suction tube; the suction tube is connected with a negative pressure suction device; the suction tube comprises a first suction tube and a second suction tube; the diameter of the first suction tube is greater than that of the second suction tube; the first suction tube passes through the sponge plug, the end of the first suction tube is a spherical structure, and the spherical structure is provided with a side hole; the second suction tube spirals in the sponge plug, and the second suction tube is provided with a side hole; the surface of the sponge plug is provided with a plastic film.

[0006] Further, the sponge plug is a circular truncated cone, the top diameter is 5-8cm, the bottom diameter is 2-3cm, and the height is 5-8cm.

[0007] The first suction tube is placed in the middle of the sponge plug, and the second suction tube is placed at the radius midpoint.

BRIEF DESCRIPTION OF DRAWINGS

[0014] In order to more clearly illustrate the technical scheme in the embodiments of the present application, the drawings needed in the embodiment description will be briefly introduced.

[0016] Figure 2 is a schematic diagram of an intestinal fistula plug according to an embodiment of the present application. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0018] The present application provides an intestinal fistula plug, as shown in Figure 1, comprising: a sponge plug 3 and suction tubes; the suction tubes are connected with negative pressure suction device; the suction tubes include a first suction tube 1 and a second suction tube 2; the diameter of the first suction tube 1 is larger than that of the second suction tube 2; the first suction tube 1 passes through the sponge plug 3, the end of the first suction tube 1 is a spherical structure 5, the spherical structure is provided with a side hole; the second suction tube is coiled in the sponge plug, and the second suction tube is provided with a side hole 4; the surface of the sponge plug 3 is provided with a plastic film.

[0019] Further, the sponge plug is a circular truncated cone, and specific sizes can be selected according to the size of the intestinal fistula in clinic, and the most optimal shape is that the top diameter is 6 cm, the bottom diameter is 3 cm, and the height is 5 cm.

[0020] The sponge plug is placed in the first suction tube, and the second suction tube is placed at the radius midpoint.

[0021] Further, the sponge plug is fixed in the fistula by the plastic film.

[0022] Further, the inner diameter of the first suction tube is 5 mm; the diameter of the spherical structure is 1 cm, and the diameter of the upper side hole of the spherical structure is 3 mm.

[0023] Further, the diameter of the second suction tube is 2 mm; the number of the upper side holes of the second suction tube is 3, and the diameter of the side hole is 2 mm.

[0024] Further, the second suction tube is coiled one circle in the sponge plug.

[0025] Specifically, the sponge plug is a circular truncated cone, and the outer cross-sectional area is larger than the inner cross-sectional area, which can effectively block the intestinal fistula and reduce the corrosion of the intestinal fluid from the periphery. Two suction tubes with different thicknesses are arranged in the sponge plug. The first suction tube 1 passes through the sponge plug, and the enlarged end with a side hole spherical structure 5 can drain the intestinal cavity contents and is not easy to block and adhere to the intestinal wall; the second suction tube 2 is coiled in the sponge plug 3, and the side hole can drain the intestinal fluid remaining in the intestinal tube and leaking into the sponge plug.

[0026] The intestinal fistula plug provided by the embodiment has the following advantages compared with the traditional negative pressure suction device: 1. Reducing the pain of the patient. The traditional negative pressure suction device sponge directly contacts the wound around the intestinal fistula, and each time the device sponge is replaced, the wound is stimulated, causing severe pain. In addition, the intestinal fluid remaining in the sponge also stimulates the granulation tissue of the wound, causing discomfort such as burning and pain. 2. The traditional negative pressure device cannot avoid the contamination of the intestinal fluid of the wound. The intestinal fluid of the digestive tract has a certain corrosion to the wound, which not only causes pain, but also delays the healing of the wound. Although the traditional negative pressure device has an suction tube embedded in the sponge, it still cannot completely suction the intestinal fluid in the sponge, which causes contamination of the wound. The new intestinal fistula plug sponge has no direct contact with the wound, so the opportunity of wound contamination is reduced. 3. The new intestinal fistula plug has good sealing effect and reduces the replacement frequency. The traditional negative pressure suction device covers the plastic film on the exudation wound. Because of the exudation of the wound, the device is easy to leak. In addition, the suction tube is thin and has no special structure at the end, which is easy to block or adhere to the intestinal wall, causing poor drainage effect of the wound or intestinal fistula fluid, and needs to be replaced at irregular times. The new intestinal fistula plug leaves the wound around the intestinal fistula, has better airtightness, and reduces the replacement frequency. In this way, the pain of the patient is reduced, and the economic burden of the patient is also reduced.

[0027] The specific operation process of the present application is as follows:

[0028] When the operator uses the device, first, the spherical structure of the first suction tube of the device is placed into the proximal jejunum of the intestinal fistula, and then the sponge plug is inserted into the intestinal fistula tube, and the plastic film is fixed at the stoma, which also plays a sealing role. If the stoma exudes more, the intestinal fistula plug can be fixed at the stoma with adhesive tape. Two suction tubes are connected to the negative pressure suction, and details are shown in Figure 2 :

[0029] a. The intestinal fluid in the stoma intestinal cavity is mainly suctioned by the thick suction tube;

[0030] b. The intestinal fluid not suctioned by the thick suction tube can be suctioned by the thin suction tube in the sponge plug;

[0031] c. The timely drainage of the intestinal fluid can keep the wound around the intestinal fistula clean;

[0032] d. The spherical suction tube end can keep the suction tube port from sticking to the wall or being blocked.

[0033] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
