Description

Technical Field

[0001] This invention relates to the field of esophageal medication technology, specifically to an esophageal medication administration device for gastroenterology. Background Technology

[0002] In the clinical diagnosis and treatment of gastroenterology, local drug therapy for esophageal lesions (such as esophagitis, esophageal ulcers, esophageal tumors, and postoperative wounds) is one of the important treatment methods. Traditional drug delivery methods mostly rely on oral administration or spraying through the endoscope tube. However, oral medications are easily affected by esophageal peristalsis and secretions, making it difficult to maintain an effective concentration at the lesion site. While endoscopic spraying can achieve direct drug delivery, existing spray tubes are mostly single-hole or annular multi-hole structures at the front end. After the drug is sprayed, it is in the form of a mist or line. On the one hand, it is easy to drift away with the patient's swallowing or breathing, and be accidentally aspirated into the airway or quickly slide into the stomach. The actual amount of drug adhering to the inner wall of the esophagus is limited. On the other hand, for non-directly visualized areas such as the posterior wall and lateral wall of the esophagus, the uniformity and controllability of the spray coverage are very poor.

[0003] After the medication reaches the esophagus, even application to the lesion surface on the esophageal wall is crucial for determining the therapeutic effect. However, the currently commonly used clinical method of medication administration is still mainly based on "spraying and relying on the esophagus's own peristalsis to spread". This passive diffusion method is very likely to cause uneven distribution of the medication in the longitudinal direction of the esophagus, forming a "drug flow" phenomenon - that is, the medication flows down rapidly along the lowest point of the esophagus, while the upper or lateral walls of the lesion area are often not adequately covered. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an esophageal medication delivery device for gastroenterology, which has the advantages of automatically delivering medication to the esophagus and evenly coating the esophageal wall, thus solving the problems of inconvenient direct application of medication to the patient's affected area and short duration of medication stay at the affected area.

A drug-applying component is fixedly connected between two adjacent positioning arc plates. A sealing circular plate is detachably connected to the bottom of the inner side of the T-tube. A pushing circular plate is slidably connected to the inner side of the T-tube. Positioning grooves are provided on both sides of the positioning arc plate. A limit ring is fixedly connected to the bottom of the inner side of the T-tube. The T-tube and the drug-applying component are detachably connected. When connected, the internal seal can be ensured. When cleaning is required, the limit ring can be released and the T-tube can be pulled out to clean the T-tube, the drug-applying component, and the positioning arc plate.

[0006] Preferably, the positioning housing assembly includes a housing body, a servo motor is fixedly connected to the top of the housing body, and a first gear is fixedly connected to the output shaft of the servo motor.

[0007] Preferably, the gas injection assembly includes a buffer ring, with a gas injection hose fixedly connected to the top of the buffer ring and a gas injection port fixedly connected to the bottom of the buffer ring.

[0008] Preferably, the drug application assembly includes a sealing arc plate, a U-shaped positioning plate fixedly connected to the outer side of the sealing arc plate, a drug injection tube fixedly connected to the outer side of the sealing arc plate, a limit ring fixedly connected to the outer side of the drug injection tube, a telescopic positioning plate slidably connected to the inner side of the U-shaped positioning plate, a pushing cone fixedly connected to the outer side of the telescopic positioning plate, a drug application circular plate fixedly connected to the outer side of the pushing cone, and a spring fixedly connected between the U-shaped positioning plate and the telescopic positioning plate.

[0009] Preferably, the telescopic positioning plate and the pushing cone have circular positioning holes on their sides. The diameter of the inside of the circular positioning hole of the pushing cone and the telescopic positioning plate is the same as the diameter of the outside of the limiting ring. The diameter of the outside of the injection tube is the same as the opening diameter of the positioning hole on the inside of the telescopic positioning plate.

[0010] Preferably, the U-shaped positioning plate and the telescopic positioning plate are fitted with a clearance, the medicine-feeding circular plate seals the positioning hole of the pushing cone, and the medicine-feeding circular plate has a medicine-feeding hole on its outer side.

[0011] Preferably, the width of the positioning groove is the same as the width of the U-shaped positioning plate, and the inner side of the sealing arc plate has an arc, the diameter of the inner arc of the sealing arc plate is the same as the inner diameter of the positioning arc plate.

[0012] Preferably, the included angle between two adjacent first injection tubes is 45 degrees, the included angle between two adjacent second injection tubes is 45 degrees, the included angle between two adjacent first injection tubes and second injection tubes is 22.5 degrees, and the included angle between two adjacent injection ports is 45 degrees.

[0013] Preferably, the gap between the bottom of the T-tube and the bottom of the inner side of the outer casing is the same as the gap between the T-tube and the positioning groove, and the second gear meshes with the first gear.

[0014] Preferably, the positioning housing assembly is connected to a robotic arm, which is a device for delivering the equipment to the esophageal patient. The robotic arm positions the positioning housing assembly and the air injection assembly, connecting the positioning housing assembly and the air injection assembly. When the medication application assembly rotates, the angle between the positioning housing assembly and the air injection assembly will not change. The robotic arm is equipped with a drive device to drive the entire equipment to rotate.

[0015] Compared with the prior art, the present invention provides an esophageal medication administration device for gastroenterology, which has the following beneficial effects: 1. This esophageal medication delivery device for gastroenterology injects gas into the buffer ring through an injection hose, and then injects it into the top of the push plate through the injection port and the first injection tube. As the air pressure at the top of the push plate increases, the push plate moves to the bottom, squeezing the medication inside the device. This allows the medication to enter the inner side of the telescopic positioning plate and the push cone through the injection tube, and then be squeezed out through the medication hole of the delivery plate, thus expelling the medication into the patient's esophagus and facilitating its delivery.

[0016] 2. This type of esophageal medication delivery device for gastroenterology uses an inflatable bladder to adhere to the inner wall of the patient's esophagus. Then, the device is rotated by the drive of a robotic arm, and the medication is evenly applied to the inner wall of the esophagus through the inflatable bladder. This facilitates the even application of medication to the patient's affected area. Depending on the actual needs, the device can be sprayed with gas through the first inflatable tube or an additional application step can be added.

[0017] 3. This type of esophageal medication delivery device for gastroenterology scrapes the medication from the side wall of the arc-shaped groove of the main body of the casing during rotation, leaving the medication temporarily in the arc-shaped groove. When the air bladder overlaps with the arc-shaped groove and expands, it pushes the medication against the inner wall of the esophagus. Then, the device is rotated by a robotic arm, which can evenly apply the medication to the affected area on the inner wall of the esophagus. This allows the medication to be applied directly and evenly to the inner wall of the esophagus, and it can adapt to esophagi of different body shapes and diameters, making the device more widely applicable.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an esophageal medication administration device for gastroenterology.

[0022] Please see Figures 1-7An esophageal medication delivery device for gastroenterology includes a positioning housing assembly 1. A medication application assembly 2 is rotatably connected to the inner side of the positioning housing assembly 1. An air injection assembly 3 is rotatably connected to the top of the medication application assembly 2. The medication application assembly 2 includes a T-shaped tube 201. A second gear 202 is fixedly connected to the top of the outer side of the T-shaped tube 201. An air injection positioning ring 203 is fixedly connected to the top of the T-shaped tube 201. A first air injection tube 204 is fixedly connected to the bottom of the inner side of the air injection positioning ring 203. A second air injection tube 205 is fixedly connected to the bottom of the inner side of the air injection positioning ring 203. An air bladder 206 is fixedly connected to the end of the second air injection tube 205 away from the air injection positioning ring 203. A positioning arc plate 2010 is detachably installed at the bottom of the T-shaped tube 201. A medication delivery assembly 207 is fixedly connected between two adjacent positioning arc plates 2010. The bottom of the inner side of the T-shaped tube 201 is detachably installed. The T-tube 201 is detachably connected to a sealing circular plate 208, and a pushing circular plate 209 is slidably connected to the inner side of the T-tube 201. Positioning grooves 2011 are provided on both sides of the positioning arc plate 2010. A limiting ring is fixedly connected to the bottom of the inner side of the T-tube 201. The T-tube 201 and the drug application component 207 are detachably connected, ensuring internal sealing during connection. When cleaning is required, the T-tube 201 is detached from the drug application component 207 and the positioning arc plate 2010 to release the limiting, and the T-tube 201 is pulled out, allowing for cleaning of the T-tube, drug application component 207, and positioning arc plate 2010. It should be further noted that the detachable connection method between the drug application component 207, the positioning arc plate 2010, and the T-tube can be any connection method such as threaded connection or limiting snap-fit, as long as it meets the functions described above. This invention does not limit the specific connection method. The medication is scraped off by the arc-shaped groove sidewall of the outer shell 101 during rotation, and is temporarily retained in the arc-shaped groove. When the air bladder 206 overlaps with the arc-shaped groove and expands, it pushes the medication towards the inner wall of the esophagus. Then, the device is rotated by the robotic arm, and the medication can be evenly applied to the affected area on the inner wall of the esophagus. This allows the medication to be applied directly and evenly to the inner wall of the esophagus, and it can adapt to different body shapes and esophagus diameters, making the device more widely applicable. The air bladder 206 is equipped with a pressure detection device to monitor the internal air pressure in real time, preventing the air bladder 206 from over-expanding and damaging the esophagus.

[0023] Furthermore, the positioning housing assembly 1 includes a housing body 101, a servo motor 102 is fixedly connected to the top of the housing body 101, and a first gear 103 is fixedly connected to the output shaft of the servo motor 102.

[0024] Furthermore, the air injection assembly 3 includes a buffer ring 301, with an air injection hose 302 fixedly connected to the top of the buffer ring 301 and an air injection port 303 fixedly connected to the bottom of the buffer ring 301.

[0025] Furthermore, the drug application assembly 207 includes a sealing arc plate 2071, a U-shaped positioning plate 2072 fixedly connected to the outer side of the sealing arc plate 2071, a drug injection tube 2073 fixedly connected to the outer side of the sealing arc plate 2071, a limit ring 2074 fixedly connected to the outer side of the drug injection tube 2073, a telescopic positioning plate 2076 slidably connected to the inner side of the U-shaped positioning plate 2072, a pushing cone 2077 fixedly connected to the outer side of the telescopic positioning plate 2076, a drug application circular plate 2075 fixedly connected to the outer side of the pushing cone 2077, and a spring 2078 fixedly connected between the U-shaped positioning plate 2072 and the telescopic positioning plate 2076. The robotic arm delivers the device to the area inside the patient's esophagus where medication needs to be applied. Then, the servo motor 102 drives the first gear 103 to rotate. The meshing of the first gear 103 and the second gear 202 then rotates the entire medication application assembly 2, aligning the air inlet 303 with the first air injection tube 204. Gas is then injected into the buffer ring 301 through the air injection hose 302 and into the top of the push plate 209 through the air inlet 303 and the first air injection tube 204. As the air pressure at the top of the push plate 209 increases, it moves downwards, compressing the medication inside the device and allowing it to pass through. The injection tube 2073 enters the inner side of the telescopic positioning plate 2076 and the pushing cone 2077, and then is squeezed out through the drug feeding hole of the drug feeding plate 2075, thus squeezing the drug into the patient's esophagus. This facilitates the delivery of the drug into the patient's esophagus. The servo motor 102 drives the first gear 103 to rotate, and then the meshing of the first gear 103 and the second gear 202 drives the entire drug application assembly 2 to rotate 22.5 degrees, so that the air injection port 303 and the second air injection tube 205 are aligned. During the rotation, the edge of the arc-shaped groove on the outer side of the outer shell 101 pushes the inclined surfaces on both sides of the pushing cone 2077, thus aligning the telescopic positioning plate 2076 and the pushing cone 2077. Plate 2076 and pushing cone 2077 retract towards the inside of U-shaped positioning plate 2072 until the outer side of pushing cone 2077 fits against the inner side of outer shell body 101, causing airbag 206 to overlap with the arc-shaped groove of outer shell body 101. Then, with continuous gas injection from the air injection component 3, airbag 206 inflates until it fits against the inner wall of the patient's esophagus. The device is rotated by a robotic arm, and the medication is evenly applied to the inner wall of the esophagus through airbag 206, facilitating even application of the medication to the lesion. The top of pushing disc 209 has a sealed medication port. After removing the sealed disc 208, medication can be added through the medication port. A battery module is also included to power servo motor 102 and to recharge it after use.

[0026] Furthermore, the telescopic positioning plate 2076 and the pushing cone 2077 have circular positioning holes on their sides. The diameter of the inside of the circular positioning hole of the pushing cone 2077 and the telescopic positioning plate 2076 is the same as the diameter of the outside of the limiting ring 2074. The diameter of the outside of the injection tube 2073 is the same as the opening diameter of the positioning hole on the inside of the telescopic positioning plate 2076.

[0027] Furthermore, the U-shaped positioning plate 2072 and the telescopic positioning plate 2076 are fitted with a clearance, the medicine loading plate 2075 seals the positioning hole of the pushing cone 2077, and the medicine loading plate 2075 has a medicine loading hole on its outer side.

[0028] Furthermore, the width of the positioning groove 2011 is the same as the width of the U-shaped positioning plate 2072, and the inner side of the sealing arc plate 2071 is provided with an arc, the diameter of the inner arc of the sealing arc plate 2071 is the same as the inner diameter of the positioning arc plate 2010.

[0029] Furthermore, the included angle between two adjacent first gas injection tubes 204 is 45 degrees, the included angle between two adjacent second gas injection tubes 205 is 45 degrees, the included angle between two adjacent first gas injection tubes 204 and second gas injection tubes 205 is 22.5 degrees, and the included angle between two adjacent gas injection ports 303 is 45 degrees.

[0030] Furthermore, the gap between the bottom of the T-shaped tube 201 and the bottom of the inner side of the outer shell body 101 is the same as the gap between the T-shaped tube 201 and the positioning groove 2011, and the second gear 202 meshes with the first gear 103.

[0031] Furthermore, the positioning housing assembly 1 is connected to the robotic arm, which is a device that delivers the equipment to the esophageal patient. The robotic arm positions the positioning housing assembly 1 and the air injection assembly 3, connecting the positioning housing assembly 1 and the air injection assembly 3. When the medication application assembly 2 rotates, the angle between the positioning housing assembly 1 and the air injection assembly 3 will not change. The robotic arm is equipped with a drive device to drive the entire equipment to rotate.

[0032] Working principle: During use, the robotic arm delivers the device to the area inside the patient's esophagus where medication needs to be applied. Then, the servo motor 102 drives the first gear 103 to rotate. Subsequently, the meshing of the first gear 103 and the second gear 202 drives the entire medication application assembly 2 to rotate, aligning the air injection port 303 with the first air injection tube 204. Gas is then injected into the buffer ring 301 through the air injection hose 302, and then injected into the top of the push plate 209 through the air injection port 303 and the first air injection tube 204. As the air pressure at the top of the push plate 209 increases, the push plate 209 moves to the bottom, squeezing the medication inside the device. The medication enters the telescopic positioning plate 2076 and the push cone 2077 through the medication injection tube 2073, and is then squeezed out through the medication application hole of the medication application plate 2075, facilitating the delivery of the medication into the patient's esophagus. After the medication is delivered into the esophagus, the servo motor 102 drives the first gear 103 to rotate. The meshing of the first gear 103 and the second gear 202 causes the entire medication application assembly 2 to rotate 22.5 degrees, aligning the air inlet 303 and the second air inlet tube 205. During the rotation, the edge of the arc-shaped groove on the outer side of the outer shell 101 pushes the inclined surfaces on both sides of the push cone 2077, causing the telescopic positioning plate 2076 and the push cone 2077 to retract towards the inside of the U-shaped positioning plate 2072 until the outer side of the push cone 2077 fits against the inner side of the outer shell 101, so that the airbag 206 overlaps with the arc-shaped groove of the outer shell 101. Then, with the continuous injection of gas by the air inlet assembly 3, the airbag 206 expands until it fits against the inner wall of the patient's esophagus. The device is rotated by the mechanical arm, and the medication is evenly applied to the inner wall of the esophagus through the airbag 206, making it easier to apply the medication evenly to the patient's affected area. When the telescopic positioning plate 2076 and the pushing cone 2077 move into the U-shaped positioning plate 2072 through the side wall of the arc-shaped groove of the outer shell 101, the medicine located inside the telescopic positioning plate 2076 and the pushing cone 2077 will be squeezed out. The side wall of the arc-shaped groove of the outer shell 101 scrapes the medicine when rotating, so that the medicine is temporarily retained in the arc-shaped groove. When the air bladder 206 overlaps with the arc-shaped groove and expands, the medicine will be adsorbed on the outside of the air bladder 206. The medicine acts as a lubricant between the air bladder 206 and the esophagus, preventing damage to the esophagus during the rotation of the equipment. By rotating the equipment through the robotic arm, the medicine can be evenly applied to the diseased area on the inner wall of the esophagus, so that the medicine can be evenly applied to the inner wall of the esophagus and can adapt to different body shapes and esophagus diameters, making the equipment more widely applicable.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
