Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an intestinal medication delivery device. Background Technology

[0002] In the clinical treatment of gastroenterology, intestinal diseases are quite common, such as ulcerative colitis and Crohn's disease. For these diseases, local drug delivery is an important treatment method, which allows the drug to act directly on the lesion site and improve the efficacy of the drug. However, traditional intestinal drug delivery devices have many drawbacks, as follows:

[0003] Traditional intestinal medication devices lack a structure for precise drug delivery. On the one hand, the distribution of medication holes is unreasonable, making it difficult to ensure that the medication evenly covers the intestinal mucosa. This results in some lesion sites not being able to fully contact the medication, greatly reducing the therapeutic effect.

[0004] In current intestinal medication administration procedures, medical staff often cannot directly observe the condition inside the intestines, which makes the medication administration operation somewhat blind. Blind operation may also cause unnecessary damage to the intestines, increasing the patient's pain and treatment risks.

[0005] During enemas and medication administration, the liquid is prone to leakage, which can not only soil the patient's clothes and bed, but also potentially cause infection.

[0006] Existing lubrication methods often require medical staff to prepare additional lubricant before the procedure, which is cumbersome and makes it difficult to achieve precise lubrication. Utility Model Content

[0007] This utility model discloses an intestinal medication applicator. Medical staff hold the control panel of the stabilizing plate and slowly insert the medication applicator head into the patient's anus. At this time, the absorbent cotton is in flexible contact with the edge of the anus under the support of the spring. The lubricant inside the storage bag is squeezed and breaks through the sealing membrane, and the lubricant flows to the anus for quantitative lubrication. The rounded corner design of the medication applicator head can reduce discomfort during insertion. With the help of the spiral bending tube on one side of the expansion tube body, the movement direction of the medication applicator head in the intestine can be flexibly changed, so that the medication applicator head accurately reaches the designated position.

[0008] In a first aspect, this disclosure provides an intestinal medication applicator, specifically comprising: an expanding tube body, wherein one side of the expanding tube body has two vertically distributed connecting bends, the two connecting bends being respectively connected to the interior of the expanding tube body, and a one-way valve being installed on the inner side of each connecting bend; one side of the expanding tube body has a bent tube, the bent tube having a spiral structure, one side of the bent tube having a connecting ring, and a medication applicator head being installed on the outer side of the connecting ring; a set of observation structures being installed on the inner side of the expanding tube body and the medication applicator head; one side of the medication applicator head having a rounded corner; and a stabilizing plate being installed on the outer side of the expanding tube body and the medication applicator head, and a set of vertically distributed absorbent cotton being installed on the outer side of the stabilizing plate.

[0009] Furthermore, a protective sleeve is provided at the middle position on the inner side of the expansion tube and the drug delivery head, and the observation structure is installed inside the protective sleeve. The observation structure consists of a camera and a conductive rod.

[0010] Furthermore, a mounting hole communicating with the protective sleeve is opened in the middle of the expansion tube body, and two positioning grooves are opened on the inner side of the mounting hole. The conductive rod of the observation structure also has two positioning grooves on its outer side, and two rubber rings are installed on the inner side of the positioning grooves.

[0011] Furthermore, a set of drug-feeding holes are respectively opened on the basis of the expansion tube and the drug-feeding head, and the drug-feeding holes are distributed in a ring array.

[0012] Furthermore, a sliding hole is formed in the middle of the stabilizing plate. The sliding hole has a cylindrical structure and its diameter is larger than that of the expansion tube and the drug delivery head.

[0013] Furthermore, a stepped groove is opened on the outer side of one side of the expansion tube, and a positioning ring is provided in the middle of one side of the stabilizing plate. A support spring is installed between the positioning ring and the stepped groove.

[0014] Furthermore, a stabilizing sleeve is provided on one side of the absorbent cotton at the upper position, and the stabilizing sleeve is installed on the outer side of the stabilizing plate.

[0015] Furthermore, two vertically distributed control panels are provided on one side of the stabilizing plate.

[0016] Furthermore, a storage bag is installed between the stabilizing plate and the absorbent cotton. An oval hole is opened at the bottom of the storage bag. The oval hole has a stepped structure, and a sealing film is installed at the stepped position of the oval hole. The absorbent cotton, the storage bag, and the sealing film work together to form a storage structure.

[0017] This invention provides an intestinal medication applicator, which has the following beneficial effects:

[0018] The annular array of drug delivery holes in the expander tube and the drug delivery head, along with the connecting bend and the injector, ensures that the medication is applied precisely and evenly to the intestinal mucosa, avoiding incomplete treatment due to uneven drug distribution.

[0019] The observation structure is built into a protective sleeve, and together with the transparent medication tip and medical display, it enables visualization of the inside of the intestine. Medical staff can observe the intestinal condition and medication process in real time, and adjust the medication position and dosage in a timely manner, thereby improving the accuracy and safety of treatment.

[0020] The spiral bend and rounded tip make it easy to change the direction of the medication tip in the intestine and insert it into the anus, reducing patient discomfort; the combination of the support spring and absorbent cotton can prevent liquid leakage and keep the area around the anus clean, improving the patient experience.

[0021] The design of the storage bag and sealing film enables convenient storage and quantitative use of the lubricant, providing automatic lubrication during medication application. This effectively reduces friction on the anus and intestines when the applicator is removed, alleviating patient pain and making the entire treatment process smoother, thus improving patient acceptance and cooperation.

[0044] In this embodiment of the disclosure, reference is made to Figures 1 to 9 As shown, an observation structure 4 is installed on the inner side of the expansion tube 1 and the drug-feeding head 3. A protective sleeve is provided in the middle of the inner side of the expansion tube 1 and the drug-feeding head 3. The observation structure 4 is installed inside the protective sleeve. The observation structure 4 consists of a camera and a conductive rod. The camera is a miniature camera from the prior art. The conductive rod and the electrical connection structure of the camera also adopt the prior art. The protective sleeve achieves the effect of hiding and protecting the observation structure 4, preventing the drug from seeping into the interior of the observation structure 4 and ensuring the stability of the observation structure 4 during use. An installation hole communicating with the protective sleeve is opened in the middle of the expansion tube 1. The installation hole facilitates the installation and removal of the observation structure 4. Two positioning grooves are opened on the inner side of the installation hole. Two positioning grooves are also opened on the outer side of the conductive rod of the observation structure 4. Two rubber rings are installed on the inner side of the positioning grooves. The rubber rings will rub and position the installed observation structure 4.

[0045] In this embodiment of the disclosure, reference is made to Figures 1 to 9 As shown, a rounded corner is provided on one side of the medication head 3. The rounded corner facilitates the insertion of the medication head 3 into the anus. A stabilizing plate 5 is installed on the outer side of the dilator tube 1 and the medication head 3. A sliding hole is opened in the middle of the stabilizing plate 5. The sliding hole is a cylindrical structure and its diameter is larger than the diameter of the dilator tube 1 and the medication head 3. The stabilizing plate 5 can move flexibly on the outer side of the dilator tube 1 and the medication head 3 in conjunction with the sliding hole.

[0046] In this embodiment of the disclosure, reference is made to Figures 1 to 9 As shown, a set of absorbent cotton 601, distributed vertically, is installed on the outer side of the stabilizing plate 5. The operator, referring to existing technology, selects a soft, absorbent, and sterilizing material for the absorbent cotton 601. A stepped groove is opened on one side of the expanding tube 1 on its outer surface. A positioning ring is located in the middle of one side of the stabilizing plate 5. A support spring is installed between the positioning ring and the stepped groove. The support spring provides elastic support to the stabilizing plate 5 and the absorbent cotton 601, ensuring that the absorbent cotton 601 remains in flexible contact with the edge of the anus during medication application. In conclusion, the elastic support ensures the fit between the absorbent cotton 601 and the anal edge, effectively preventing the outflow of enema fluid and medication, and maintaining the patient's comfort. For body cleaning, a stabilizing sleeve is provided on the upper side of the absorbent cotton 601. The stabilizing sleeve is installed on the outer side of the stabilizing plate 5. The material of the stabilizing sleeve is non-woven fabric, which is a common material in the prior art. The material of the stabilizing sleeve can also be plastic or rubber. Non-woven fabric is soft and skin-friendly, while plastic and rubber are more stable. The absorbent cotton 601 and the stabilizing sleeve can be firmly installed on the outer side of the stabilizing plate 5. There are two vertically distributed control panels on one side of the stabilizing plate 5. Medical staff can adjust the position of the stabilizing plate 5 by hand. It can be concluded that the design of the control panels greatly improves the convenience of operation for medical staff, making the operation of adjusting the position of the stabilizing plate 5 simpler and faster, and saving operation time.

[0047] In this embodiment of the disclosure, reference is made to Figures 1 to 9 As shown, a storage bag 602 is installed between the stabilizing plate 5 and the absorbent cotton 601. The storage bag 602 is used to store lubricant. An oval hole with a stepped structure is opened at the bottom of the storage bag 602.

The absorbent cotton 601, the storage bag 602, and the sealing membrane 603 work together to form the storage structure 6. The sealing membrane 603 is a thin film structure that can be used in the present invention. When the medical staff applies pressure to the stabilizing plate 5 and the absorbent cotton 601 at the same time, the lubricant inside the storage bag 602 is squeezed and breaks through the sealing membrane 603. At this time, the lubricant inside the storage bag 602 can flow to the anus for quantitative lubrication. It can be concluded that the design of the storage bag 602 realizes the convenient storage and quantitative use of lubricant, avoids the trouble of preparing additional lubricant, improves the efficiency of operation, and the quantitative lubrication can effectively reduce the friction on the anus and intestines during the medication application process, reduce the patient's pain, and make the medication application process smoother.

[0048] Example 2, based on Example 1, with reference to Figures 1 to 9 As shown, you will need a USB signal cable and a monitor with a miniature camera. Select a monitor model commonly used in the medical field.

[0049] Example 3, based on Example 1, with reference to Figures 1 to 9 As shown, sealant can be further filled between the absorbent cotton 601 and the storage bag 602 to ensure stable assembly of the absorbent cotton 601 and the storage bag 602.

[0050] The working principle of this embodiment:

[0051] Medical staff prepare a USB signal cable and a miniature camera monitor commonly used in the medical field. Connect one end of the USB signal cable to the miniature camera in observation structure 4 and the other end to the monitor. Prepare the corresponding drugs and enema fluid according to the actual treatment needs and put them into the appropriate injection device.

[0052] Medical staff securely assemble the expansion tube 1 and the drug delivery head 3 using a friction locking structure, and then put the stabilizing plate 5 on the outside of the expansion tube 1 and the drug delivery head 3 so that it can move flexibly through the sliding hole. Adjust the position of the stabilizing plate 5, align the positioning ring with the stepped groove on the expansion tube 1, and install the support spring so that the stabilizing plate 5 and the absorbent cotton 601 are elastically supported.

[0053] Medical staff connect the injection devices containing medication and enema fluid to two connecting bends 101 via tubing. Holding the control panel of the stabilizing plate 5, the medical staff slowly inserts the medication head 3 into the patient's anus. At this time, the absorbent cotton 601 flexibly contacts the edge of the anus under the support of the spring. The lubricant inside the storage bag 602 is squeezed and breaks through the sealing membrane 603, and the lubricant flows to the anus for quantitative lubrication. The rounded corner design of the medication head 3 can reduce discomfort during insertion. During the insertion process, the condition inside the intestine can be observed through the monitor. Based on the image fed back by the miniature camera, the spiral bend tube on one side of the expanding tube 1 is used to flexibly change the direction of movement of the medication head 3 in the intestine, so that the medication head 3 accurately reaches the designated position.

[0054] In the enema injection procedure, medical staff push the injection device to inject the enema solution into the intestine through the connecting bend 101 and the expanding tube 1. At this time, the one-way valve 2 ensures that the enema solution flows in one direction.

[0055] During the intestinal medication administration procedure, medical staff push the injection device containing the medication, allowing the medication to be evenly applied to the intestinal mucosa through the medication port of the expansion tube 1 and the medication head 3. The monitor is continuously observed during the medication administration process to ensure that the medication is evenly distributed. After the intestinal medication administration is completed, the expansion tube 1 and the medication head 3 are removed.
