Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an interventional puncture and drainage device. Background Technology

[0002] In the medical field, interventional puncture and drainage is a common and important treatment method, widely used in the treatment of diseases such as fluid aspiration and abscess drainage. By puncturing, the fluid in the body is drained out, which plays a key role in the diagnosis and treatment of patients. In interventional puncture and drainage procedures, the collection of drainage fluid is an indispensable part.

[0003] Referring to the patent document: Patent Publication No. CN117982209A, Patent Publication Date 2024-05-07, specifically, it is an interventional puncture and drainage device; it includes a puncture needle and a wearable component. The wearable component includes an operation board with an opening and two sets of straps, each with a corresponding male and female Velcro fastener. In use, the operator secures the straps to the patient using the male and female Velcro fasteners, firmly attaching the operation board to the patient. The angle of the positioning sleeve is adjusted using an angle adjustment component, and then the medical staff performs the puncture procedure by passing the puncture needle through the positioning sleeve. This eliminates the need for the operator to hold the puncture needle throughout the procedure, reducing hand fatigue and preventing needle dislodgement due to patient movement. By activating a negative pressure pump, the air pressure inside the drainage box is reduced, enabling drainage through the puncture needle.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: Currently, existing interventional puncture drainage devices, when collecting fluids, mostly use relatively simple tubing connections during the fluid diversion and collection process, making it difficult to achieve precise diversion control. This requires medical staff to frequently change the drainage bags. For example, when facing the need for fluid collection and sampling at multiple times, medical staff need to frequently and manually change the drainage bags. The operation process is not only time-consuming and labor-intensive, but also requires removing the drainage bag from the drainage tube each time it is changed, which increases the risk of infection or sample contamination due to the frequent need to change the drainage bags.

[0005] Therefore, this utility model provides an interventional puncture and drainage device. Utility Model Content

[0006] To address the problems of existing drainage systems being simple, lacking diversion control, resulting in frequent bag changes that are labor-intensive and prone to infection and contamination, the purpose of this invention is to provide an interventional puncture drainage device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an interventional puncture and drainage device, comprising a cylindrical body, wherein a collection mechanism is provided in the middle of the cylindrical body for collecting the fluid drained through puncture, the collection mechanism comprising: The conveying assembly includes several fixed plates located in the middle of the cylinder. A bidirectional cylinder is fixedly installed in the middle of each fixed plate. A clamping plate is fixedly installed at the drive end of each bidirectional cylinder. A collection cylinder is clamped in the middle of each clamping plate. A branch pipe is slidably clamped in the upper part of the cylinder. The branch pipe has several pipes distributed in a branching manner. A valve body is provided in the middle of each pipe. The lower part of each pipe is in sealed contact with the input end of the collection cylinder. An electric push rod is fixedly installed in the middle of the top of the cylinder. The drive end of the electric push rod is fixedly installed in the middle of the bottom end of the branch pipe. The telescopic component is located in the middle of the cylinder to facilitate workers in taking the collection cylinder.

[0008] Preferably, the telescopic assembly includes a double-ended screw rotatably mounted in the middle of the cylinder, with movable blocks threadedly mounted on both sides of the double-ended screw, and several connecting rods rotatably mounted on the outer sides of the two movable blocks. The other ends of the multiple connecting rods are movably mounted in the middle of one side of the fixed plate, and a drive assembly is provided at the lower part of the cylinder.

[0009] Preferably, an upper cover is fixedly installed at the top of the cylinder, the upper part of the bifurcated tube slides through the middle of the upper cover, and several windows corresponding to the collection cylinder are opened on one side of the cylinder.

[0010] Preferably, a groove is provided in the middle of one side of each of the fixing plates, and one side of each of the clamping plates is slidably engaged in the middle of the groove.

[0011] Preferably, a number of support rods are fixedly installed in the middle of the cylinder, and the two sides of a number of fixing plates are slidably locked onto the outer surface of the support rods.

[0012] Preferably, the drive assembly is fixedly installed on the lower cover at the bottom of the cylinder, a servo motor is fixedly installed in the middle of the lower cover, and the bottom end of the double-headed screw is fixedly installed on the drive end of the servo motor. Beneficial effects

[0013] This invention provides an interventional puncture and drainage device. Compared with the prior art, it has the following advantages: 1. This application uses a bidirectional cylinder to drive the clamping plate to move, firmly clamping the collection cylinder. Simultaneously, driven by an electric actuator, the branch pipe can move up and down. Combined with the intelligent control of the valve body on the branch pipe body by the control system, it can achieve precise diversion and collection of liquid. During operation, the electric actuator drives the branch pipe to move upward and separate, facilitating the loading of the collection cylinder. After loading, the electric actuator retracts to seal the branch pipe and the collection cylinder. Medical staff can accurately introduce the liquid into the corresponding collection cylinder by controlling the opening and closing of the valve body, meeting the needs of rapid and time-segmented sampling, effectively improving the efficiency and accuracy of liquid collection, and enabling medical staff to obtain multiple bottles of sample liquid at one time.

[0014] 2. This application uses a servo motor to drive a double-headed screw to rotate, causing two moving blocks to move synchronously relative to each other or in opposite directions. Then, the extension and retraction of the fixed plate is achieved through linkage transmission. When it is necessary to load or unload the collection cylinder, the servo motor drives the double-headed screw to rotate, causing the fixed plate to carry the collection cylinder out of the cylinder body through the window. Medical staff can operate directly from the outside of the cylinder body without having to go into the cylinder. This allows medical staff to quickly remove and replace the collection cylinder, greatly improving the convenience and safety of medical staff operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: an interventional puncture and drainage device, including a cylinder 1, with a collection mechanism 2 in the middle of the cylinder 1 for collecting the fluid drained by puncture. The collection mechanism 2 includes: The conveying assembly 21 includes several fixed plates 214 disposed in the middle of the cylinder 1. A bidirectional cylinder 215 is fixedly installed in the middle of each fixed plate 214. The bidirectional cylinder 215 is an Airtac SUJ12-25 miniature bidirectional cylinder. The cylinder body is made of lightweight aluminum alloy, and both ends of the cylinder are equipped with buffer devices to effectively reduce the impact force when the clamping plate 216 moves, ensuring stable clamping of the collection cylinder 218. The drive ends of the bidirectional cylinders 215 are fixedly installed... There is a clamping plate 216, and the inner side of the clamping plate 216 is provided with an anti-slip rubber pad. The surface of the rubber pad is designed with a wavy texture to increase the friction between it and the collection cylinder 218, ensuring a firm clamping. A collection cylinder 218 is clamped in the middle of each set of clamping plates 216. The collection cylinder 218 is made of transparent medical-grade plastic material, and the cylinder body is marked with clear scale lines with a scale accuracy of 1ml, which makes it easy for medical staff to accurately read the liquid volume. A branch tube 211 is slidably clamped on the upper part of the cylinder body 1. The branch tube 211... 11 has several branched pipes, each with a valve body 212 located in the middle. Each valve body 212 includes a valve body, a valve core, and a control element. The valve core is movably disposed within the valve body to control the opening and closing of the corresponding branch pipe or to regulate the flow rate. The control element drives the valve core to move, thereby changing the fluid flow state of the branch pipe. The opening and closing of the valve body 212 is intelligently controlled by a control system. The lower parts of each branch pipe 211 are connected to a collection... The input end of the cylinder 218 is sealed, and the sealing point uses a medical-grade sealing ring with good elasticity and sealing performance. An electric actuator 213 is fixedly installed at the middle of the top of the cylinder 1. The driving end of the electric actuator 213 is fixedly installed at the middle of the bottom end of the branch pipe 211. The electric actuator 213 is a miniature linear electric actuator, model NKLA76, used to drive the branch pipe 211 to move up and down, so as to realize the docking and separation of the branch pipe body of the branch pipe 211 with the input end of the collection cylinder 218. The telescopic component 22 is located in the middle of the cylinder 1 to facilitate the staff to take the collection cylinder 218.

[0024] The telescopic assembly 22 includes a double-headed screw 221 rotatably installed in the middle of the cylinder 1. Moving blocks 223 are threadedly installed on both sides of the double-headed screw 221. Several connecting rods 222 are rotatably installed on the outer side of the two moving blocks 223. The other end of the multiple connecting rods 222 is movably installed in the middle of one side of the fixed plate 214. A drive assembly is provided at the lower part of the cylinder 1.

[0025] A top cover 2111 is fixedly installed at the top of the cylinder 1. The upper part of the bifurcated pipe 211 slides through the middle of the top cover 2111. Several windows 2112 corresponding to the collection cylinder 218 are opened on one side of the cylinder 1. The position of the windows 2112 corresponds to the position and number of the collection cylinder 218. Soft protective strips are provided on the edges of the windows 2112 to prevent the collection cylinder 218 from being scratched when it enters or exits.

[0026] A groove 217 is provided in the middle of one side of several fixing plates 214, and one side of several clamping plates 216 is slidably locked in the middle of the groove 217. The groove 217 is used to limit and guide the clamping plates 216, so as to ensure that the clamping plates 216 can stably limit and fix the collecting cylinder 218.

[0027] Several sets of support rods 219 are fixedly installed in the middle of the cylinder 1. Both sides of several fixing plates 214 are slidably locked onto the outer surface of the support rods 219. The support rods 219 are used to support and guide the fixing plates 214 so that they can slide back and forth stably inside the cylinder 1.

[0028] The drive assembly is fixedly installed on the lower cover 225 at the bottom of the cylinder 1. A servo motor 224 is fixedly installed in the middle of the lower cover 225. The bottom end of the double-headed screw 221 is fixedly installed on the drive end of the servo motor 224. The servo motor 224 can be the M542-H micro servo motor from Leadshine Intelligent, with a size of 40mm×40mm×48mm. Driven by the servo motor 224, the double-headed screw 221 can be rotated, so that the two moving blocks 223 can move synchronously relative to each other or in opposite directions. Through the transmission of the connecting rod 222, the fixed plate 214 can be moved telescopically.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, when the electric actuator 213 is in the extended state, it drives the branch pipe 211 to move up to the initial position on the upper part of the cylinder 1. The lower part of the branch pipe 211 separates from the input end of the collection cylinder 218 to prepare for loading the collection cylinder 218. The cylinder servo motor 224 starts and drives the double-headed screw 221 to rotate. Because the threads on both sides of the double-headed screw 221 are reversed, the two moving blocks 223 move in opposite directions, driving the connecting rod 222 to unfold and push the fixing plate 214 to slide along the support rod 219, so that the collection cylinder 218 extends out of the outside of the cylinder 1 through the window 2112. At this time, the empty collection cylinder 218 is placed on one side of the fixing plate 214. Under the contraction of the bidirectional cylinder 215, the two clamping plates 216 move relative to each other to clamp and fix the two ends of the collection cylinder 218. After several collection cylinders 218 are installed on one side of the fixed plate 214, the double-headed screw 221 is driven to rotate in the opposite direction by the reverse drive of the servo motor 224. That is, under the transmission of the connecting rod 222, the fixed plates 214 move synchronously towards the middle of the cylinder 1, thereby bringing the collection cylinders 218 into the cylinder 1. The input end of the collection cylinder 218 is located directly below the branch pipe of the bifurcation pipe 211. By the retraction of the electric actuator 213, the bifurcation pipe 211... The branch tube 1 is sealed to the input end of the collection tube 218 to complete the operation. The main tube end of the branch tube 211 is connected to the patient's puncture drainage tube. When the medical staff presses the button, the valve 212 on the branch tube of the branch tube 211 is opened, allowing the liquid to flow into the collection tube 218. Each valve 212 can be driven independently, allowing the opening and closing of each valve 212 to be controlled independently, which can facilitate the rapid collection and sampling needs of medical staff. During retrieval, the bifurcation tube 211 is first moved away from the collection tube 218 by the electric push rod 213 through a reverse operation. Then, the collection tube 218 is extended from the window 2112 by the servo motor 224. After the medical staff holds the collection tube 218, the two clamping plates 216 move in opposite directions under the drive of the bidirectional cylinder 215, thereby releasing the clamping limit on the collection tube 218, so that the collection tube 218 can be removed and a new collection tube 218 can be installed simultaneously.
