Description

Technical Field

[0001] This utility model relates to a pressure roller transmission mechanism, and in particular to a disposable intestinal dilation balloon catheter, belonging to the field of medical device technology. Background Technology

[0002] A disposable intestinal dilation balloon catheter is a medical device specifically designed for intestinal examinations or treatments. It mainly consists of a balloon, a catheter, and a connecting part. The balloon is the core component, typically made of a material with good elasticity and biocompatibility (such as latex or silicone), capable of inflating under pressure. The catheter is generally made of medical-grade plastic (such as PVC or polyurethane) and is used to deliver gas or liquid to inflate the balloon, while ensuring the balloon's connection to the external inflation or liquid filling device during operation. The connecting part ensures a tight connection with the inflation device during operation to prevent gas or liquid leakage. Its main function is to inflate the balloon by injecting an appropriate amount of gas (such as air) or liquid (such as saline). In intestinal examinations, such as colonoscopy, when there are narrow areas or many folds in the intestine that obstruct the field of vision, the balloon catheter can be inserted into the intestine to inflate the balloon at a suitable location, opening up the intestine and creating a better viewing space for the examination instrument (such as a colonoscope). This helps doctors to more clearly observe the mucosal condition inside the intestine and detect lesions such as polyps, inflammation, and tumors. In intestinal surgery, it can be used to expand the intestine, providing sufficient operating space for surgical procedures (such as intestinal anastomosis), allowing the surgery to proceed more smoothly.

[0003] In the prior art, such as the utility model with application number 202222884327.2, a double-lumen catheter for intestinal dilation is disclosed. The double-lumen catheter is provided with a guide balloon and a dilation balloon. The small-capacity guide balloon is located at the front end of the double-lumen catheter and is used to indicate the position of the double-lumen catheter in the intestine. The large-capacity dilation balloon is longer and is used to dilate narrow intestines to facilitate the operator's treatment of patients with intestinal stenosis.

[0004] The above-mentioned applications still have shortcomings:

[0005] The dilation balloon of this double-lumen catheter used for intestinal dilation has no internal limiting component, and the dilation balloon is prone to uneven force. Therefore, when injecting air or liquid into the dilation balloon, if the air inlet position is singular or the elasticity of the balloon is inconsistent, it will lead to excessive or insufficient dilation in a local area, resulting in unstable and reasonable dilation, which is not conducive to the doctor's examination and treatment work.

[0006] To address these issues, a disposable intestinal dilation balloon catheter was designed. Utility Model Content

[0007] The main purpose of this invention is to provide a disposable intestinal dilation balloon catheter to solve the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A disposable intestinal dilation balloon catheter includes a catheter body with a lubrication assembly. The catheter body is wrapped with a balloon layer, and baffles are evenly and annularly distributed inside the balloon layer. One end of each baffle is fixedly connected to the outside of the catheter body. A through hole is opened in the middle of the catheter body, and air holes are evenly distributed on the inner wall of the through hole. The through hole is connected to the balloon layer through the air holes. An injection tube is installed at the top of one end of the catheter body and is connected to the end of the through hole. A one-way valve is provided at the top of the injection tube, and an expulsion assembly is provided on one side of the injection tube.

[0010] Preferably, the lubrication assembly includes a feed pipe, an injection hole, a fixing port, and a cavity guide. The feed pipe is located at the bottom of the conduit body near the injection pipe. The injection hole is located inside the conduit body and below the through hole, and the end of the injection hole is connected to the feed pipe. The fixing port is located at the end of the conduit body away from the conduit body and is connected to the injection hole. A one-way valve is provided inside the fixing port. The cavity guide is located at the end of the conduit body away from the injection pipe, and micropores are uniformly opened on the outer side of the cavity guide.

[0011] Preferably, the discharge assembly includes a discharge pipe and a flow regulating cap. The discharge pipe is installed on one side of the injection pipe, and a one-way valve is provided at the top of the discharge pipe. A flow regulating cap is provided at one end of the one-way valve.

[0012] Preferably, the end of the cavity guide is set as an arc surface, and all micro-holes are set with conical holes.

[0013] Preferably, a protective layer is provided on the outer side of the catheter body near the injection tube, and the protective layer is provided with anti-slip texture.

[0014] Preferably, all baffles are fan-shaped, and the baffles and air holes are evenly spaced on the outside of the duct body.

[0015] Preferably, the outside of the injection tube is provided with an anti-slip layer, and the outside of the anti-slip layer is provided with an organosilicon quaternary ammonium salt antibacterial coating.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] I. This utility model, through the coordinated use of the catheter body, balloon layer, baffles, through-hole, air hole, injection tube, and one-way valve, enables the baffles to be evenly distributed inside the balloon layer. This not only helps to evenly pull the balloon layer and promote its expansion, but also applies a certain resistance to the initially introduced fluid, preventing excessive fluid entry and resulting in more uniform fluid filling. This not only improves patient comfort during the dilation process but also enhances operational safety, thereby improving the practicality of this disposable intestinal dilation balloon catheter.

[0018] II. This utility model utilizes the combined use of an inlet tube, injection hole, fixing port, one-way valve, hollow guide head, and micropores. Lubricating fluid is injected through the inlet tube and discharged from the micropores to cover the intestinal wall, achieving a pre-lubricating effect. This facilitates the smooth advancement of the balloon layer into the intestinal tract, making the balloon layer easier to insert. Furthermore, it allows for easy replenishment of lubricating fluid during the process, thereby facilitating the examination and treatment of multiple parts of the intestine and improving the ease of use of this disposable intestinal dilation balloon catheter.

[0019] Third, this utility model uses the discharge pipe, flow regulating cover and one-way valve in combination. The suction component is connected to the flow regulating cover. The flow rate of the flow regulating cover is adjusted to extract the fluid in the balloon layer and adjust the expansion degree of the balloon layer. The fluid flows in one direction, which prevents cross-contamination of the fluid and makes it convenient for medical staff to use. Attached Figure Description

[0032] Example 1

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment proposes a disposable intestinal dilation balloon catheter, including a catheter body 1, a lubrication assembly 2 on the catheter body 1, a balloon layer 3 wrapped around the outside of the catheter body 1, baffles 4 evenly and annularly distributed inside the balloon layer 3, and one end of each baffle 4 being fixedly connected to the outside of the catheter body 1, a through hole 5 in the middle of the catheter body 1, air holes 6 evenly distributed on the inner sidewall of the through hole 5, and the through hole 5 communicating with the balloon layer 3 through the air holes 6, an injection tube 7 installed at the top of one end of the catheter body 1, and the injection tube 7 communicating with the end of the through hole 5, a one-way valve 8 at the top of the injection tube 7, and an expulsion assembly 9 on one side of the injection tube 7.

[0034] After the catheter body 1 and balloon layer 3 are inserted into the intestine, they are connected to the one-way valve 8 via an inflator or liquid inflation device. Gas or liquid, such as saline, is injected into the infusion tube 7, and then enters the through hole 5 through the infusion tube 7. The gas is then evenly introduced into the space between the balloon layer 3 and the catheter body 1 through the air hole 6, so that the space between the balloon layer 3 and the catheter body 1 is filled and the balloon layer 3 expands. At the same time, the baffle 4 has a pulling effect on the inside of the expanded balloon layer 3, preventing the balloon layer 3 from being overfilled in some areas, so that the filling fluid is more evenly distributed. At the same time, the baffle 4 has a certain barrier effect on the fluid, which resists the fluid that first enters the balloon layer 3 from the direction of the infusion tube 7, and causes the fluid to be diverted to the leftmost side, so as to promote the even delivery of fluid.

[0035] Example 2

[0036] The solution in Example 1 will be further described below with reference to its specific working method.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the lubrication assembly 2 further includes a feed pipe 201, an injection hole 202, a fixing port 203, and a cavity guide head 205. The feed pipe 201 is located at the bottom of the conduit body 1 near the injection pipe 7. The injection hole 202 is opened inside the conduit body 1 and is located below the through hole 5. The end of the injection hole 202 is connected to the feed pipe 201. The fixing port 203 is opened at the end of the conduit body 1 away from the conduit body 1 and is connected to the injection hole 202. A one-way valve 204 is provided inside the fixing port 203. The cavity guide head 205 is located at the end of the conduit body 1 away from the injection pipe 7. Micropores 206 are uniformly opened on the outer side of the cavity guide head 205.

[0038] The lubrication component 2 is first placed into the intestine, and then sterile lubricating fluid is injected into the injection hole 202 through the feed tube 201. The fluid enters the cavity guide head 205 through the fixing port 203 and the one-way valve 204 in sequence, until the lubricating fluid is discharged into the intestinal wall from the micropore 206. The lubrication component 2 then extends forward. Under the lubrication of the lubricating fluid, it is conducive to the advancement of the balloon layer 3 into the intestine, making it easier for the balloon layer 3 to be placed into the intestine.

[0039] like Figure 1 As shown, in a preferred embodiment, based on the above method, the discharge assembly 9 further includes a discharge pipe 901 and a flow regulating cover 902. The discharge pipe 901 is installed on one side of the injection pipe 7. A one-way valve 903 is provided at the top of the discharge pipe 901, and a flow regulating cover 902 is provided at one end of the one-way valve 903.

[0040] The suction component is connected to the flow regulating cover 902. The flow rate of the flow regulating cover 902 is adjusted to extract the fluid in the balloon layer 3, adjust the expansion degree of the balloon layer 3, and completely extract the fluid to facilitate the removal of the entire catheter body 1 from the intestine. The one-way valve 903 is set to make the fluid flow in one direction to prevent cross-contamination of the fluid.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, the end of the cavity guide 205 is further provided as an arc surface, and the micro-holes 206 are all provided with conical holes.

[0042] The curved surface of the hollow guide 205 reduces damage to the intestines, while the conical micropores 206 prevent the backflow of mucus and other fluids from the intestines into the hollow guide 205.

[0043] like Figure 1 As shown, in a preferred embodiment, based on the above method, a protective layer is further provided on the outer side of the catheter body 1 near the injection tube 7, and the protective layer is provided with anti-slip texture.

[0044] The protective layer and anti-slip texture make it easier for staff to support the catheter body 1, making operation more convenient.

[0045] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the baffles 4 are all configured as fan-shaped pieces, and the baffles 4 and the air holes 6 are evenly spaced on the outside of the guide tube 1.

[0046] The fan-shaped baffles 4 better fit and connect with the balloon layer 3 and the catheter body 1 simultaneously. The baffles 4 and the vents 6 are spaced apart, which facilitates the injection of filling fluid from the vents 6 into the space between the baffles 4.

[0047] like Figure 1 As shown, in a preferred embodiment, based on the above method, an anti-slip layer is further provided on the outside of the injection tube 7, and an organosilicon quaternary ammonium salt antibacterial coating is provided on the outside of the anti-slip layer.

[0048] The anti-slip layer facilitates operation and use by medical staff, while the organosilicon quaternary ammonium salt antibacterial coating enhances antibacterial properties and prevents contamination at the connection between the injection tube 7 and the air or liquid filling components.

[0049] Example 3

[0050] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0051] The lubrication component 2 is first inserted into the intestine. Then, sterile lubricating fluid is injected into the injection port 202 through the inlet tube 201. The fluid sequentially passes through the fixing port 203 and the one-way valve 204 into the hollow guide head 205. The lubricating fluid is then discharged into the intestinal wall through the micropores 206. The lubrication component 2 then extends forward. Lubricated by the lubricating fluid, the catheter body 1 and balloon layer 3 advance into the intestine to the desired expansion position. A gas or liquid injection device is connected to the one-way valve 8, injecting gas or liquid, such as physiological saline, into the injection tube 7. The gas or liquid then enters the through-hole 5 through the injection tube 7 and is then evenly introduced between the balloon layer 3 and the catheter body 1 through the air vents 6, filling the space between them and causing the balloon layer 3 to expand and bulge. The baffle 4 acts as a pull on the inside of the expanded balloon layer 3, preventing excessive local filling of the balloon layer 3 and making the filling fluid distribution more uniform. At the same time, the baffle 4 has a certain blocking effect on the fluid, providing some resistance to the fluid that first enters the balloon layer 3 from the direction of the injection tube 7, causing the fluid to be diverted to the far left, promoting uniform fluid input. The suction component is connected to the flow regulating cover 902. Adjusting the flow rate of the flow regulating cover 902 allows the fluid in the balloon layer 3 to be extracted, adjusting the degree of expansion of the balloon layer 3. After the operation is completed, the fluid is completely extracted by the suction component, and the balloon layer 3 returns to its original shape, facilitating the removal of the entire catheter 1 from the intestine. The one-way valve 903 ensures unidirectional fluid flow, preventing cross-contamination of the fluid.

[0052] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
