Description

Technical Field

[0001] This utility model relates to an ointment infusion device for the treatment of enteritis, belonging to the technical field of drug infusion devices. Background Technology

[0002] Enteritis is a common digestive system disease with various treatment methods, among which medicated infusion is a common therapy. Medicated infusion typically involves directly injecting a drug solution into the intestines, utilizing the local action of the drug to reduce inflammation and improve symptoms. This method is generally suitable for some patients with moderate to severe enteritis, especially when oral medications are ineffective. The advantage of medicated infusion is that it can quickly deliver the drug to the affected area, enhancing the local efficacy. However, although medicated infusion can relieve symptoms to some extent, its effect is often limited. Many patients report that while medicated infusion can relieve some symptoms in the short term, the effect is not lasting, and sometimes discomfort occurs, such as abdominal bloating or discomfort during the infusion process.

[0003] Compared to intravenous infusions, ointments demonstrate a more lasting and effective treatment for enteritis. Ointments typically contain anti-inflammatory, analgesic, and intestinal mucosal repairing ingredients, acting directly on the intestinal surface to relieve inflammation and promote mucosal repair. The advantage of these ointments lies in their topical nature, avoiding the discomfort associated with infusions and providing continuous local protection, reducing side effects on other parts of the gastrointestinal tract. Ointments are also more stable and effective than liquid medications, making them suitable for long-term use. Furthermore, ointments reduce drug volatility, improving therapeutic efficacy and aiding in better intestinal absorption, thus achieving better therapeutic results.

[0004] Currently, liquid medicine infusion devices cannot be used for ointment infusion, and existing ointment infusion devices lack pre-infusion intestinal cleansing. Intestinal cleansing is typically required before ointment infusion to remove waste, residues, and potential pathogens, thus creating a better environment for drug absorption and efficacy. Furthermore, existing ointment infusion devices use a syringe to infuse ointment externally; if the connecting tube is too long, ointment may remain inside the tube, resulting in significant waste.

[0005] Therefore, an ointment infusion device for treating enteritis was designed. It can not only cleanse the intestines with medicine, but also infuse ointment into the lesion site after cleansing, ensuring that the medicine can directly act on the affected area, avoiding obstruction by impurities and enhancing the efficacy of the medicine. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide an ointment infusion device for the treatment of enteritis, which solves the problems of single function and large amount of ointment used by current ointment infusion devices.

[0007] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0008] An ointment infusion device for treating enteritis includes a reservoir bag, an infusion tubing, an infusion tubing, a cleaning tubing, an inflation tubing, an inflation device, and an inflatable balloon.

[0009] The two ends of the infusion tube are smooth rounded. The inside of the infusion tube is sealed and divided into a proximal ointment storage chamber and a distal cleaning chamber by a partition. The ointment storage chamber is filled with ointment for treating enteritis. An infusion hole is opened at the proximal end of the ointment storage chamber and a cleaning hole is opened at the distal end of the cleaning chamber.

[0010] The distal end of the cleaning tube is sealed, the proximal end of the cleaning tube is connected to the distal cleaning chamber of the infusion tube, and the storage bag is connected to one side of the distal end of the cleaning tube through the infusion tube.

[0011] The inflation tube is coaxially inserted into the cleaning tube. The proximal end of the inflation tube is sealed through the partition and connected to the proximal end of the infusion tube. The distal end of the inflation tube is sealed through the distal end of the cleaning tube and connected to the inflation device. The section of the inflation tube located in the ointment storage cavity is a balloon section. An inflatable balloon is wrapped around the outside of the balloon section. The ointment drug surrounds the uninflated inflatable balloon. An inflation hole for inflating the inflatable balloon is opened on the balloon section.

[0012] Preferably, an infusion valve is installed on the infusion tube.

[0013] Preferably, the cleaning tube is marked with graduation lines.

[0014] Preferably, the inflation device is a syringe or an inflatable balloon.

[0015] Preferably, the inflatable balloon is composed of a rubber balloon, a first one-way valve, and a second one-way valve. The first one-way valve is installed at the distal end of the rubber balloon and only allows external air to enter the rubber balloon. The second one-way valve is installed at the proximal end of the rubber balloon and only allows air to exit from the rubber balloon. The inflatable balloon is sealed to the inflation tube through the second one-way valve.

[0016] Preferably, the inflation port is located at the distal end of the balloon segment.

[0017] Preferably, the inner wall of the ointment storage cavity is provided with a strip-shaped groove connecting the proximal and distal ends.

[0018] The beneficial effects of this utility model are:

[0019] (1) An infusion tube with an ointment storage chamber and a cleaning chamber is used to clean the intestinal lesion site first, and then the ointment drug is squeezed out from the ointment storage chamber through the expansion balloon and infused into the intestinal lesion site, ensuring that the drug can directly act on the lesion site, avoiding obstruction by impurities, and enhancing the efficacy of the drug.

[0020] (2) By storing the medicine in the infusion tube and inflating the expansion bladder with an external inflation device, the ointment can be squeezed out of the infusion tube, avoiding the ointment from staying in the long connecting tube and thus causing ointment waste, and saving the amount of ointment used.

[0028] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0029] In this article, "proximal" refers to the region of the intestine near the stomach or the beginning of the intestine; "distal" refers to the end of the intestine, the part near the anus, and also the end closest to the operator.

[0030] like Figures 1-5As shown, in one embodiment, the ointment infusion device for treating enteritis includes a reservoir bag 1 and an infusion tube 2. The reservoir bag 1 can contain plain saline solution, or a medication for treating enteritis can be added to the saline solution.

[0031] It also includes an infusion tube 3, a cleaning tube 4, an inflation tube 5, an inflation device 6, and an inflatable balloon 7.

[0032] The two ends of the infusion tube 3 are smooth rounded. The inside of the infusion tube 3 is sealed and divided into a proximal ointment storage chamber 302 and a distal cleaning chamber 303 by a partition 301. The ointment storage chamber 302 is filled with an ointment for treating enteritis. An infusion hole 304 is provided at the proximal end of the ointment storage chamber 302, and a cleaning hole 305 is provided at the distal end of the cleaning chamber 303.

[0033] The capacity of the ointment storage chamber 302 (the volume available for ointment infusion after removing the air tube 5 and the uninflated balloon 7) can be in various sizes such as 1 ml, 3 ml, and 5 ml as needed.

[0034] The distal end of the cleaning tube 4 is sealed, and the proximal end of the cleaning tube 4 is connected to the distal cleaning chamber 303 of the infusion tube 3. The storage bag 1 is connected to the distal side of the cleaning tube 4 through the infusion tube 2.

[0035] The inflation tube 5 is coaxially inserted into the cleaning tube 4. The proximal end of the inflation tube 5 is sealed through the partition 301 and connected to the proximal end of the infusion tube 3. The distal end of the inflation tube 5 is sealed through the distal end of the cleaning tube 4 and connected to the inflation device 6. The section of the inflation tube 5 located in the ointment storage cavity 302 is the balloon section 501. The balloon section 501 is covered with an inflatable balloon 7. The ointment drug surrounds the uninflated inflatable balloon 7. An inflation hole 502 for inflating the inflatable balloon 7 is provided on the balloon section 501.

[0036] The infusion tube 3, cleaning tube 4, and inflation tube 5 are made of one-piece plastic structure, and the expansion balloon 7 is made of elastic balloon. They are all packaged in disposable aseptic packaging at the time of shipment.

[0037] How to use:

[0038] (1) When using, open the disposable packaging bag, take out the integrated infusion tube 3, cleaning tube 4 and air infusion tube 5, and inject the ointment for treating enteritis into the ointment storage cavity 302 through the infusion hole 304.

[0039] (2) Based on the distance from the lesion site of enteritis to the anus, make two marks on the cleaning tube 4 (adhesive tape can be used for marking; when the first mark is at the anus, the cleaning hole 305 corresponds to the lesion site; when the second mark is at the anus, the irrigation hole 304 corresponds to the lesion site). Insert the irrigation tube 3 and the cleaning tube 4 into the rectum. When the tube reaches the proximal end of the lesion site along the intestine, the first mark will just reach the anus. At this time, extend it inward by 5-10 mm.

[0040] (3) Connect the port on the far side of the cleaning tube 4 to the infusion tube 2 of the storage bag 1, and rinse the enteritis lesion site through the height pressure difference between the suspended storage bag 1 and the cleaning hole 305.

[0041] (4) After rinsing, connect the distal end of the inflation tube 5 to the syringe 601 or the balloon 9, and then pull the cleaning tube 4 outward. When the second mark is in the anus, extend it inward by 5-10 mm and start inflating the balloon 7 through the inflation device 6. The balloon will squeeze the ointment out of the irrigation hole 304. While squeezing out, slowly pull the cleaning tube 4 outward so that the ointment is applied from the proximal end to the distal end of the lesion site, covering the lesion site as much as possible. After the ointment is released, completely remove the irrigation tube 3 from the intestine.

[0042] Since the inflation device 6 does not participate in the internal connection of the human intestine, it can be reused after thorough disinfection, while other structures are treated as disposable medical waste.

[0043] In the above scheme, the cleaning chamber 303 outputs cleaning fluid to the lesion site, which can clean the intestinal lesion site. Then, the inflatable bladder squeezes the ointment out of the ointment storage chamber 302 and infuses it into the lesion site of the intestine, ensuring that the drug can act directly on the lesion site, avoiding obstruction by impurities, and enhancing the efficacy of the drug.

[0044] In the above scheme, the medicine is stored in the ointment storage cavity 302 of the infusion tube 3, and then the expansion bladder is inflated to squeeze the ointment out of the infusion tube 3. This avoids the ointment waste problem caused by the ointment staying in the long connecting tube when using the existing infusion device, and saves the amount of ointment used.

[0045] In some embodiments, an infusion valve 8 is installed on the infusion tubing 2. In some cases, such as when the position of the infusion tubing 3 needs to be readjusted, the infusion valve 8 can be used to temporarily stop or start the flushing process as needed.

[0046] In some embodiments, the cleaning tube 4 is marked with graduation lines 401. The graduation lines 401 enable better positioning of the first and second marks.

[0047] In some embodiments, the inflation device 6 is a syringe 601 or an inflatable balloon 9.

[0048] Inflate the balloon with syringe 601, requiring the operator to apply continuous pressure. The ointment is gradually squeezed out through the transmission of the balloon 7.

[0049] like Figures 1-6 As shown, an inflatable balloon 9 is used, which consists of a rubber balloon 901, a first one-way valve 902, and a second one-way valve 903. The first one-way valve 902 is installed at the distal end of the rubber balloon 901 and allows only external air to enter the rubber balloon 901. The second one-way valve 903 is installed at the proximal end of the rubber balloon 901 and allows only air to exit the rubber balloon 901. The inflatable balloon 9 is sealed to the inflation tube 5 through the second one-way valve 903. Air can be continuously inflated into the inflation balloon 7 through the first one-way valve 902 and the second one-way valve 903 without continuous pressure, making inflation and ointment extrusion easier.

[0050] In some embodiments, the inflation port 502 is located at the distal end of the balloon segment 501. When the inflation port 502 begins to inflate, the distal balloon 7 of the balloon segment 501 is first subjected to gas pressure and inflates, which facilitates the sequential extrusion of the ointment from the distal end to the proximal end.

[0051] like Figure 3 , Figure 5 As shown, in some embodiments, a strip-shaped groove 306 connecting the proximal and distal ends is provided on the inner wall of the ointment storage cavity 302. When the inflatable balloon 7 does not inflate gradually from the distal end to the proximal end, the ointment at the distal end can return to the infusion hole 304 at the proximal end through the reserved strip-shaped groove 306, making the ointment extrusion more thorough.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
