Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a spherical adsorption structure and its esophageal fistula device. Background Technology

[0002] Currently, in patients with esophageal fistulas, after external medication, the fistula gradually shrinks during treatment, and fluid (such as pus, exudate, and necrotic secretions) accumulates within it, requiring aspiration. Operators typically create a disposable suction head using materials such as medical gauze. This head is connected to a drainage tube, and an esophagoscope is used to insert the self-made suction head into the fistula opening within the esophagus. The suction head is then used to absorb the exudate from the fistula, keeping it dry. However, the self-made suction head (i.e., placing it directly into the fistula) is inefficient and has poor suction effect. Therefore, how to overcome the problems of low efficiency and poor suction effect in esophageal fistula fluid aspiration is crucial.

[0003] In addition, when the fistula is small in the later stages of treatment, how to improve the coverage of the suction head on the fistula and ensure that the fluid inside the esophageal fistula does not overflow becomes a technical problem that needs to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a spherical adsorption structure and its esophageal fistula device, mainly to solve the following problems in the prior art: 1. How to overcome the low efficiency and poor adsorption effect of esophageal fistula liquid adsorption operation; 2. How to improve the coverage effect of the adsorption head on the fistula opening and ensure that the liquid inside the esophageal fistula does not overflow when the fistula opening is small in the later stage of treatment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a spherical adsorption structure, characterized in that: the adsorption structure includes a drainage tube and a sponge adsorption head, the sponge adsorption head is in the shape of a hollow sphere, one end of the drainage tube is provided with several air windows, the hollow part of the sponge adsorption head wraps around the drainage tube, and the sponge adsorption head covers the air windows.

[0006] Furthermore, several air vents are evenly distributed on the drainage tube.

[0007] Furthermore, the drainage tube is provided with a marking section for displaying the length, and the marking section is arranged from one end of the drainage tube to the other end.

[0008] Furthermore, the drainage tube includes a first tube body and a second tube body. The hollow part of the sponge adsorption head is wrapped around the first end of the first tube body. The fourth end of the second tube body is connected to a negative pressure device. A snap-fit ​​structure for quick installation is provided between the second end of the first tube body and the third end of the second tube body.

[0009] Furthermore, the outer side of the second end of the first tube is provided with several locking teeth, and the inner side wall of the third end of the second tube is provided with several locking grooves, the locking teeth and locking grooves forming a snap-fit ​​structure;

[0010] The outer side of the second end of the first tube is provided with a sealing ring for forming a sealing structure with the inner wall of the third end of the second tube or with the opening of the third end of the second tube. The sealing ring is located below the retaining teeth.

[0011] An esophageal fistula device is characterized in that: the esophageal fistula device includes a negative pressure bottle and the above-mentioned spherical adsorption structure, the air inlet of the negative pressure bottle is connected to the other end of the drainage tube, the air outlet of the negative pressure bottle is connected to a suction airbag for extracting gas from the negative pressure bottle to form a negative pressure, and the suction airbag is provided with a one-way valve.

[0012] An esophageal fistula device, characterized in that: the esophageal fistula device includes a negative pressure bottle and a spherical adsorption structure, the air inlet of the negative pressure bottle is connected to the fourth end of the second tube, the air outlet of the negative pressure bottle is connected to a suction bag for extracting gas from the negative pressure bottle to form a negative pressure, and the suction bag is provided with a one-way valve.

[0013] Furthermore, the outer side of the negative pressure bottle has two symmetrical concave arc surfaces.

[0014] Furthermore, the outer side of the negative pressure bottle has a recessed area for accommodating the suction airbag.

[0015] In view of the above technical features, the present invention has the following beneficial effects:

[0016] 1. This utility model provides a spherical adsorption structure with a sponge adsorption head on the drainage tube. The operator does not need to make their own adsorption head and can use it directly (i.e., place the sponge adsorption head at the fistula opening of the esophageal fistula), which improves the efficiency of the whole process. The sponge material of the sponge adsorption head enhances the adsorption effect and absorbs more liquid faster.

[0017] 2. This utility model features a spherical adsorption structure, particularly useful in the later stages of treatment when the fistula is small. The spherical sponge adsorption head, placed inside the esophagus, not only completely covers the fistula but also, due to its spherical design, allows part of the spherical surface of the adsorption head to embed within the fistula, achieving a better and tighter coverage. This ensures that fluid within the esophageal fistula does not leak out and is completely absorbed by the adsorption head, which draws out pus and other fluids, keeping the wound dry. The spherical shape also increases the degree of compression of the sponge body from all angles, making it suitable for patients with narrow esophagi. The spherical shape also facilitates easy entry and exit from the esophagus, reducing patient discomfort. Compared to cylindrical adsorption structures, in the later stages of treatment when the fistula is small, the spherical sponge adsorption head satisfies the need to absorb pus and other fluids from the fistula while being smaller and more economical in terms of material.

[0018] 3. The present invention provides an esophageal fistula device, which is connected to a negative pressure bottle and a suction bag for drawing out the gas in the negative pressure bottle to form a negative pressure. It is applicable in various scenarios, and is simple to operate and convenient to use. Attached Figure Description

[0037] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0038] See Figures 1 to 4In specific embodiment 1, a spherical adsorption structure is provided, including a drainage tube 2 and a sponge adsorption head 1. The sponge adsorption head 1 is a hollow sphere that can cover the fistula opening 9-1 of the esophageal fistula 9 (i.e., the passage opening where the esophageal fistula 9 connects to the esophagus 8). Especially in the later stages of treatment when the fistula opening 9-1 is small, the spherical sponge adsorption head 1 placed inside the esophagus 8 can not only completely cover the fistula opening 9-1, but also, due to its spherical design, a portion of the spherical surface of the sponge adsorption head 1 can be embedded inside the fistula opening 9-1, achieving a better and tighter coverage effect of the sponge adsorption head 1 on the fistula opening 9-1. This ensures that the fluid inside the esophageal fistula 9 does not overflow and can be completely absorbed by the sponge adsorption head 1. The sponge adsorption head 1 absorbs the pus and other fluids overflowing from the fistula opening 9-1, keeping the wound dry. The spherical shape of the sponge adsorption head 1 can also increase the degree of compression of the sponge body from all angles, making it suitable for patients with a narrow esophagus 8. The spherical sponge suction head 1 is also easy to enter and exit the esophagus 8, reducing patient discomfort. Compared to the cylindrical suction structure, when the fistula 9-1 is smaller in the later stages of treatment, the use of the spherical sponge suction head 1 can meet the need to absorb the pus and other fluids overflowing from the fistula 9-1, while also being smaller in size and saving on the material of the sponge suction head 1.

[0039] One end 2-1 of the drainage tube is provided with several air windows 2-3. The hollow part 1-1 of the sponge suction head 1 wraps around the drainage tube 2, and the sponge suction head 1 covers the air windows 2-3. Under the action of the negative pressure device, the drainage tube 2 is drawn out through the air windows 2-3. The liquid adsorbed in the sponge suction head 1 (such as pus, exudate and necrotic secretions) will slowly gather in the hollow part 1-1 and enter the drainage tube 2 through the air windows 2-3, and be drawn into the negative pressure device by the drainage tube 2.

[0040] Preferably, a number of air windows 2-3 are evenly distributed on the drainage tube 2. The air windows 2-3 can be arranged in multiple rows horizontally and vertically, or they can be distributed in a staggered manner. All of these are to absorb the liquid stored in the sponge adsorption head 1 more evenly from all directions and improve the suction efficiency.

[0041] Preferably, the drainage tube 2 is provided with a marking part 2-4 for displaying the length, such as raised or recessed numerical marks, or printed numerical marks. The marking part 2-4 is arranged from one end 2-1 of the drainage tube to the other end 2-2 of the drainage tube, so that the operator can intuitively see the length of the drainage tube 2-1 that extends into the patient's esophagus 8, and grasp the depth or position of the sponge suction head 1 in the esophagus 8, thereby improving the efficiency of the use of the sponge suction head 1.

[0042] In this embodiment 1, the specific usage of the adsorption structure for an esophageal fistula device is as follows: The operator, using an esophagoscope, places the sponge adsorption head 1 inside the esophagus 8, corresponding to the fistula opening 9-1 of the esophageal fistula 9. The sponge adsorption head 1 can then seal the fistula opening 9-1, immediately absorbing the liquid produced by the esophageal fistula 9. Utilizing the tiny pores and channels inside the sponge, the liquid produced by the esophageal fistula 9 rises or flows in these pores (i.e., the capillary action of the sponge), realizing the function of the sponge adsorption head 1 in adsorbing the liquid. Then, a negative pressure device connected to the other end of the drainage tube 2 generates negative pressure, and the liquid adsorbed by the sponge adsorption head 1 enters the drainage tube 2 through the air window 2-3. The drainage tube 2 then leads the liquid into the negative pressure device, completing the operation of aspirating the liquid from the fistula opening 9-1 of the esophageal fistula 9.

[0043] In this embodiment 1, the sponge suction head 1 is a disposable item. It needs to be replaced with a new sponge suction head 1 every 4-5 days in order to continuously absorb the liquid produced by the esophageal fistula 9 and keep the fistula 9-1 dry.

[0044] See Figures 5 to 6 In specific embodiment 2, an adsorption structure for an esophageal fistula device is provided. The difference between embodiment 2 and embodiment 1 is that the drainage tube 2 includes a first tube body 3 and a second tube body 4. The hollow portion 1-1 of the sponge adsorption head 1 wraps around the first end 3-1 of the first tube body. The fourth end 4-2 of the second tube body is connected to a negative pressure device. A snap-fit ​​structure 5 for quick installation is provided between the second end 3-2 of the first tube body and the third end 4-1 of the second tube body. The split-type drainage tube 2 design, combined with the sponge adsorption head 1, makes the entire adsorption structure more convenient and comfortable to use. The procedure can be simplified into three steps: First, leave the fourth end 4-2 of the second tube outside the body for later connection to the negative pressure device. Insert the third end 4-1 of the second tube into the patient's nasal cavity, then through the patient's throat and mouth, and remove the third end 4-1. Second, leave the second end 3-2 of the first tube outside the body for later connection to the third end 4-1. Insert the first end 3-1 of the first tube, along with the sponge suction head 1, into the esophagus 8 through the patient's mouth and throat until the sponge suction head 1 seals the fistula opening 9-1 of the esophageal fistula 9. Third, insert the first... The second end 3-2 of the tube body is connected to the third end 4-1 of the second tube body, for example, the two are snapped together to form a whole. Finally, the fourth end 4-2 of the second tube body is pulled, so that the connection between the second end 3-2 of the first tube body and the third end 4-1 of the second tube body (for example, the snap-fit ​​structure 5) is retracted into the oral cavity and into the esophagus 8. At this time, one end of the drainage tube 2 is located in the esophagus 8, and the other end of the drainage tube 2 is located outside the nasal cavity and connected to the negative pressure device. During this process, the sponge suction head 1 enters the esophagus 8 through the mouth and throat, without passing through the nasal cavity, so there will be no problem that the sponge suction head 1 cannot be inserted into the nasal cavity, thus improving the patient's comfort.

[0045] Preferably, the outer side of the second end of the first tube 3 is provided with a plurality of locking teeth 5-1, and the inner side wall of the first end of the second tube 4 is provided with a plurality of locking grooves 5-2. The locking teeth 5-1 and the locking grooves 5-2 form a snap-fit ​​structure 5. By simply inserting the second end 3-2 of the first tube into the third end 4-1 of the second tube, the locking teeth 5-1 can be quickly engaged with the locking grooves 5-25-2, thereby realizing the function of quick connection between the first tube 3 and the second tube 4. The structure is simple and the operation is convenient.

[0046] The outer surface of the second end 3-2 of the first tube is provided with a sealing ring 3-3 for forming a sealing structure with the inner wall of the third end 4-1 of the second tube. The sealing ring 3-3 is located below the retaining teeth 5-1. When the first tube 3 and the second tube 4 are quickly connected, the sealing ring 3-3 precisely seals the opening of the third end 4-1 of the second tube, or the sealing ring 3-3 can also fit against the inner wall of the third end 4-1 of the second tube to form a sealing structure. No air leakage will occur at the connection between the first tube 3 and the second tube 4, avoiding affecting the negative pressure environment inside the drainage tube 2 and avoiding affecting the adsorption effect of the adsorption structure.

[0047] See Figures 7 to 9 In specific embodiment 3, this embodiment 3 provides an esophageal fistula device, which includes an adsorption structure used in the esophageal fistula device of the aforementioned embodiment. The air inlet 6-3 of the negative pressure bottle is connected to the other end 2-2 of the drainage tube (for example, the air inlet 6-3 of the negative pressure bottle is connected to the fourth end 4-2 of the second tube). The air outlet 6-4 of the negative pressure bottle is connected to a suction bag 7 for drawing out the gas in the negative pressure bottle 6 to form a negative pressure (for example, the air outlet 6-4 of the negative pressure bottle and the suction bag 7 are connected by a trachea 7-1). The suction bag 7 ensures that the negative pressure bottle 6 can maintain a negative pressure environment, so that the use of the esophageal fistula device is not limited by the site or conditions (for example, no power is required, just manually press the suction bag 7). The suction bag 7 is equipped with a one-way valve (not shown in the attached figure). The one-way valve can only release air and cannot allow air to enter.

[0048] The negative pressure bottle 6 has two symmetrical concave arc surfaces 6-1 on its outer side, which makes it easy for the operator to hold the negative pressure bottle 6 with one hand.

[0049] The outer side of the negative pressure bottle 6 has a recessed area 6-2 for storing the suction bag 7. The suction bag 7 can be stored in the recessed area 6-2 at any time, making the operation simple and convenient.
