Description

Technical Field

[0001] The present invention relates to the technical field of contrast agent manufacturing, and particularly relates to a gastrointestinal ultrasound contrast agent manufacturing device and a usage method thereof. Background Art

[0002] In modern life, due to reasons such as irregular diet of people, the incidence of gastrointestinal diseases has been increasing year by year. In the medical field, gastrointestinal ultrasound examination, as a non-invasive and convenient diagnostic method, has received increasing attention. Gastrointestinal ultrasound examination often requires patients to take contrast agents to cooperate with ultrasound examination equipment to form clear images of the gastrointestinal tract, so as to facilitate doctors to diagnose gastrointestinal diseases in a timely manner. However, in the preparation of gastrointestinal ultrasound contrast agents, there are many problems with some existing gastrointestinal ultrasound contrast agent manufacturing devices, which are difficult to meet the needs of clinical accurate diagnosis. On the one hand, some existing contrast agent manufacturing equipment and its processes are relatively rough, often resulting in problems such as insufficient grinding of contrast agent raw materials and uneven mixing with solvents, which easily affect the quality of ultrasound imaging, and thus affect doctors' observation of the internal structure of the gastrointestinal tract, and are prone to misdiagnosis or missed diagnosis. On the other hand, due to poor temperature control of the prepared contrast agent, after patients take too cold or too hot contrast agents, it may cause discomfort to the gastrointestinal tract and even interfere with the examination results.

[0003] In addition, for existing gastrointestinal ultrasound contrast agent preparation devices, such as a gastrointestinal ultrasound contrast agent preparation device and a contrast agent preparation method provided in the publication number CN115121161A, including a main body, a stirring component and a vibrating component, a feed pipe is fixedly connected and communicated at the top of the main body, a discharge pipe is fixedly connected and communicated at the side wall of the main body, a baffle is fixedly connected to the inner wall of the main body, a stirring rod and an auxiliary frame are arranged in the main body, the stirring component is arranged on the baffle, and the application makes the stirring rod reciprocate in a spiral trajectory vertically through the stirring component, so as to improve the mixing quality. The vibrating component is arranged on the stirring component and is driven by the movement of the stirring component, so that the stirring rod vibrates when moving to the upper part to avoid the adhesion of raw materials during the mixing process. However, since this application only considers the problem of sufficient stirring during the preparation of contrast agents, the obtained contrast agent after preparation cannot be directly used for gastrointestinal ultrasound examination because of its high temperature, that is, it can only be used for the prefabrication of contrast agents and cannot adapt to the scenario where contrast agents need to be used in a timely manner, resulting in a narrow scope of application and low imaging examination efficiency. Summary of the Invention

[0004] In view of the above problems, the present invention aims to provide a gastrointestinal ultrasound contrast agent manufacturing device.

The stirring rod in the mixing cup is driven by the linkage mechanism to stir the mixing cup, so that the contrast agent is fully dissolved, thereby improving the stirring effect of the contrast agent and further improving the preparation efficiency.

[0019] 2. By designing the temperature control component, a multi-turn cooling pipe that can be wound around the outside of the mixing cup is set, and the cold water in the cooling pipe is driven to flow by the peristaltic pump.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0024] The inventor's research found that there are many problems with existing gastrointestinal ultrasound contrast agent manufacturing devices, which are difficult to meet the needs of clinical precise diagnosis. On the one hand, the existing contrast agent manufacturing equipment and processes are relatively rough, often resulting in problems such as insufficient grinding of contrast agent raw materials and uneven mixing with solvents, which can easily affect the quality of ultrasound imaging, and thus affect doctors' observation of the internal structure of the gastrointestinal tract, prone to misdiagnosis or missed diagnosis. On the other hand, due to poor temperature control of the prepared contrast agent, after patients take the too cold or too hot contrast agent, it may cause discomfort to the gastrointestinal tract and even interfere with the examination results. In addition, when some existing preparation devices crush the contrast agent raw materials, they do not consider the situation that the raw materials may adhere to the crushing cavity, resulting in waste of raw materials.

[0025] Based on the above findings, this application proposes a gastrointestinal ultrasound contrast agent manufacturing device, designing a crushing component. By setting crushing blades in the crushing cavity, the input contrast agent raw materials are crushed, and the raw materials are sieved through the sieve holes on the bottom plate of the crushing cavity. At the same time, the brush is driven by the linkage mechanism on the outside to brush off the raw materials attached to the inner wall of the crushing cavity. Design a temperature control component. By winding multiple cooling pipes around the outside of the mixing cup and combining with a peristaltic pump to drive the cold water in the cooling pipes to flow, the hot water inside the mixing cup is cooled to a temperature that can be taken directly, so as to improve the examination efficiency. Combine the linkage mechanism to synchronously drive the crushing component and the temperature control component to start, and automatically send the prepared contrast agent out of the housing for the patient to use, with the advantages of high preparation efficiency, strong immediacy, convenient use and simple structure.

[0026] Refer to Figures 1 - 2 , this application discloses a gastrointestinal ultrasound contrast agent manufacturing device, including a housing 1. The housing 1 is an overall hollow cuboid structure, and its material can be selected as a high-strength plastic with a certain transparency. In some embodiments, a feed inlet 101 for adding contrast agent raw materials is provided at the top of the housing 1, and a plurality of water injection ports 102 are respectively provided on the other side of the top. In addition, a circular through hole for facilitating the passage of the mixing cup 2 is provided at the bottom of the housing 1.

[0027] Refer to Figures 3 - 5 , a crushing component 3 for crushing the contrast agent raw materials is provided inside the housing 1. The crushing component 3 includes a crushing cavity 301. The crushing cavity 301 is an overall hollow cylindrical cavity structure, and its material can be selected as a metal or plastic material with a relatively high strength. In some embodiments, the top of the crushing cavity 301 is fixed to the lower part of the top of the housing 1 by means of bolt connection or the like, and the top of the crushing cavity 301 is directly opposite to the feed inlet 101. Then, when in use, the contrast agent raw materials to be crushed can be added into the crushing cavity 301 by opening the feed inlet 101. A bottom plate 302 matching the inner cavity thereof is fixedly arranged at the bottom of the crushing cavity 301. A plurality of filtering holes 303 are evenly arranged on the bottom plate 302. A crushing blade 304 capable of being driven by a first motor 305 is arranged on the bottom plate 302. A feeding channel 306 communicating with the mixing cup 2 is arranged below the bottom plate 302. Then, by starting the first motor 305, the crushing blade 304 can be driven to crush the contrast agent raw material, and the raw material with a smaller particle size can fall into the feeding channel 306 through the filtering holes 303, and then be conveyed to the mixing cup 2 to be mixed with hot water, so as to prepare the contrast agent for gastrointestinal ultrasound examination. It should be noted that the size of the crushing blade 304 should be maintained at a length relatively close to the crushing cavity 301. In the drawings of the present application, the length of the crushing blade 304 is drawn shorter for the convenience of observing the internal structure of the crushing cavity 301. In some embodiments, a cleaning mechanism 307 capable of being driven by a linkage mechanism 5 to clean the inner wall of the crushing cavity 301 is further arranged in the crushing cavity 301. Refer to Figure 6 , the cleaning mechanism 307 includes a slip ring gear 3071. An annular chute structure is arranged at the edge of the bottom plate 302 close to the edge. A slip ring gear 3071 is rotatably arranged in the chute structure. The slip ring gear 3071 includes an annular main body closely matching the chute structure. A gear ring is fixedly arranged below the annular main body. At the same time, a through groove enabling the gear ring on the slip ring gear 3071 to contact the outside is arranged at the edge of the bottom plate 302. A slip ring gear driving gear 5021 meshing with the slip ring gear 3071 is arranged at the through groove. Then, in an embodiment of the present invention, the linkage mechanism 5 can drive the driving gear 5021 to rotate, and then drive the slip ring gear 3071 to rotate relative to the bottom plate 302 and the crushing cavity 301. Two vertical brushes 3072 are fixedly arranged above the slip ring gear 3071 by means of threaded connection or the like. The bristles on the brushes 3072 can just fit the inner wall of the crushing cavity 301. Then, when the slip ring gear 3071 rotates, the two brushes 3072 can be driven to brush off the contrast agent raw material attached to the inner wall of the crushing cavity 301, so that the crushing blade 304 can completely crush the input raw material, and further prevent waste of raw materials.

[0028] Refer to Figure 9 and Figure 10, inside the outer shell 1, there is also a temperature control component 4 for controlling the temperature of the contrast agent inside the mixing cup 2. The temperature control component 4 first includes a hot water tank 401 fixed to the inner top of the outer shell 1. On one side of the hot water tank 401, there is also a first cold water tank 402 and a second cold water tank 403, which are also fixed to the inner top of the outer shell 1 and are interconnected. The tops of the hot water tank 401, the first cold water tank 402, and the second cold water tank 403 are respectively connected to the water injection ports 102 opened on the outer shell 1 to facilitate the addition of hot water or cold water; The bottom of the hot water tank 401 is connected to the mixing cup 2 through a hot water pipe 4011. In some embodiments, the hot water pipe 4011 is made of a metal material with high strength and strong corrosion resistance. Its bottom is fixed with a cup cover 7 that can exactly cover the mixing cup 2. The cup cover 7 is also provided with a plurality of heat dissipation holes 701 for heat dissipation. On the other side of the cup cover 7, it is also fixedly connected to the feeding channel 306 in the crushing component 3. At the same time, a valve can be optionally provided at the connection between the hot water pipe 4011 and the hot water tank 401, and the hot water in the hot water tank 401 can be manually controlled to be injected into the mixing cup 2 to soak the contrast agent raw materials after crushing treatment. In addition, a scale groove 4012 is provided on one side of the hot water tank 401 to facilitate the operator to observe and control the amount of hot water added to the mixing cup 2. At the same time, in some embodiments, a scale table 201 can also be optionally opened on the side surface of the mixing cup 2 to mark the amount of contrast agent placed in the mixing cup 2, facilitating the operator to observe the content of the contrast agent in the cup or determine the amount of contrast agent required for gastrointestinal ultrasound examination; At the bottom of the first cold water tank 402 and the second cold water tank 403, there is a cooling mechanism 404 for cooling the inside of the mixing cup 2. In some embodiments, the cooling mechanism 404 includes a first cold water pipe 4041 connected to the first cold water tank 402. The first cold water pipe 4041 is bent around the peristaltic pump 4044, and its end is vertically downward and is connected to the top of the cooling pipe 4042 wound around the outside of the mixing cup 2. The bottom of the cooling pipe 4042 is connected to the bottom of the second cold water pipe 4043. The second cold water pipe 4043 is vertically arranged, and its top is connected to the bottom of the second cold water tank 403. That is, the cold water stored in the first cold water tank 402 and the second cold water tank 403 can flow through the first cold water pipe 4041, the cooling pipe 4042, and the second cold water pipe 4043 to cool the contrast agent with a higher temperature in the mixing cup 2 so that the patient undergoing gastrointestinal ultrasound examination can take it immediately; In an embodiment of the present invention, at the first cold water pipe 4041, a peristaltic pump 4044 fixed above the cup lid 7 is provided. The peristaltic pump 4044 includes a peristaltic pump main shaft 4045. At one end of the peristaltic pump main shaft 4045, two peristaltic pump rollers 4046 are fixed. When the peristaltic pump main shaft 4045 drives the peristaltic pump rollers 4046 to rotate, the upper and lower sides of the bent section of the first cold water pipe 4041 can be repeatedly squeezed, thereby driving the cold water in the cooling mechanism 404 to flow. And at one end of the peristaltic pump main shaft 4045 away from the two peristaltic pump rollers 4046, a peristaltic pump drive gear 5022 is fixed. Then the peristaltic pump 4044 can be started by the linkage mechanism 5 through the peristaltic pump drive gear 5022; Refer to Figure 7 And Figure 8 , the linkage mechanism 5 includes a second motor 501. In an embodiment of the present invention, a horizontally arranged fixed plate is fixed on one side of the hot water tank 401. The second motor 501 is fixed below the fixed plate by means of bolt connection or the like. The motor shaft of the second motor 501 is vertically downward, and two drive gears 502 are fixed on the motor shaft, including a slip ring gear drive gear 5021 meshing with the slip ring gear transmission wheel 3073 and a peristaltic pump drive gear 5022 meshing with the peristaltic pump transmission gear 4047. Then when the second motor 501 is started, the cleaning mechanism 307 and the cooling mechanism 404 can be driven through the two drive gears 502; In some embodiments, the motor shaft of the second motor 501 is vertically downward and penetrates through the cup lid 7 and then extends into the mixing cup 2. At the bottom of the motor shaft, multiple stirring rods 504 capable of stirring the contrast agent in the mixing cup 2 are fixed. That is, when the second motor 501 is started, the inside of the mixing cup 2 can be stirred; In some embodiments, a fan blade 503 with a threaded outer edge is provided between the stirring rod 504 on the motor shaft and the drive gear 502. At the same time, a thread matching the fan blade 503 is provided on the inner wall of the top of the mixing cup 2, and the overall height of the thread in the mixing cup 2 should be slightly higher than the overall height of the thread of the fan blade 503. Then when the second motor 501 is started, the fan blade 503 can be driven to rotate synchronously; In addition, a base 6 is provided below the outer shell 1. A plurality of electric push rods 603 fixed to the bottom of the outer shell 1 are provided at the four corners of the base 6. A spring cup mat 601 is fixed at the center of the base 6. The spring cup mat 601 includes a circular support plate with an area slightly larger than the bottom of the mixing cup 2. Four springs are fixed between the bottom of the circular support plate and the base 6. A guiding slide rod 602 is also provided in the middle of the four springs. A clamping block 605 is provided at the center of the top of the circular support plate. A rectangular clamping groove matching the clamping block 605 is formed at the center of the bottom of the mixing cup 2. When the mixing cup 2 is placed on the spring cup mat 601, it can be regarded as the bottom of the mixing cup 2 being clamped and fixed by the spring cup mat 601. When the second motor 501 drives the fan blade 503 to rotate, the mixing cup 2 can be gradually slid downward through the screw action. The elastic force of the spring in the spring cup mat 601 can just lift the empty mixing cup 2. When the mixing cup 2 filled with the contrast agent gradually slides downward, it will also compress the spring cup mat 601 and the guiding slide rod 602 downward; A plurality of gravity sensors 604 are evenly arranged around the clamping block 605 on the spring cup mat 601. In some embodiments, a controller is further included. The gravity sensors 604 are electrically connected to the controller. The gravity sensors 604 can transmit the collected data to the controller. The controller compares the collected data with a set threshold. When the collected data ≥ the set threshold, an operation instruction is issued to control the electric push rods 603 to start working. In practical applications, the threshold for the controller to control the electric push rods 603 to work can be set as the weight after a certain amount of contrast agent is filled in the mixing cup 2. When the mixing cup 2 slides downward and presses the spring cup mat 601, the four electric push rods 603 can be started to slowly push the whole outer shell 1 upward. When the top of the mixing cup 2 is completely separated from the fan blade 503, the electric push rods 603 can lift the outer shell 1 to a height where the bottom is higher than the top of the mixing cup 2, so that the patient can take the contrast agent in the mixing cup 2.

[0029] In some embodiments, an electromagnet or other structure capable of adsorbing the spring coaster 601 may be selectively provided at the center of the base 6, so that after the patient removes the mixing cup 2, the spring coaster 601 will not reset under the elastic force of the spring, so as to place a new mixing cup 2 above the spring coaster 601 for preparing a new contrast agent. When the mixing cup 2 is placed on the spring coaster 601, the electromagnet is turned off to make the spring coaster 601 reset upward. The gravity sensor 604 is only used to trigger the elongation of the electric push rod 603, and then the electric push rod 603 can be manually controlled to shorten, so that the mixing cup 2 gradually extends into the housing 1. When the top of the mixing cup 2 contacts the fan blade 503, the second motor 501 can be controlled to drive the fan blade 503 to rotate in the reverse direction, so as to drive the mixing cup 2 and the spring coaster 601 to move upward synchronously again through the thread action until the mixing cup 2 fits with the cup cover 7, thus completing the preparation work for the next contrast agent preparation.

[0030] A method for using a gastrointestinal ultrasound contrast agent manufacturing device includes the following steps: S1. Add the contrast agent raw materials into the crushing chamber 301, crush the contrast agent raw materials through the crushing blade 304, and then send them into the mixing cup 2 through the feeding channel 306; S2. Add hot water into the mixing cup 2 through the hot water tank 401, and start the linkage mechanism 5 to drive the stirring rod 504 to stir the contrast agent raw materials and hot water in the mixing cup 2, so that the prepared contrast agent is evenly mixed to ensure the imaging effect of gastrointestinal ultrasound detection; S3. The linkage mechanism 5 synchronously starts the cleaning mechanism 307 to brush down the contrast agent raw materials adhering to the inner wall of the crushing chamber 301, send them into the mixing cup 2 again after crushing treatment, and at the same time start the peristaltic pump 4044 in the cooling mechanism 404 to drive the cold water to flow, so as to cool the mixing cup 2. At the same time, the fan blade 503 rotates to further cool the mixing cup 2, and the mixing cup 2 gradually slides downward through the thread action; S4. The mixing cup 2 slides downward and presses down the spring coaster 601. When the gravity value received by the gravity sensor 604 on the spring coaster 601 exceeds the preset value, the electric push rod 603 can be controlled to extend and lift the housing 1 upward, so that the mixing cup 2 is completely separated from the housing 1 for the patient to take. Actual application cases

[0031] Before a patient undergoes a gastrointestinal ultrasound examination, a quantitative amount of contrast agent raw materials is weighed and added into the crushing chamber 301 through the feeding port 101, and sufficient hot water and cold water are added into the hot water tank 401 and the two cold water tanks through the water injection port 102 to complete the preparation work; Start the first motor 305 to make the crushing blade 304 crush the contrast agent raw material and send it into the mixing cup 2. Add the hot water in the hot water tank 401 into the mixing cup 2. When adding hot water, the amount of hot water added can be controlled by observing the scale groove 4012, so that the content ratio of the contrast agent raw material to the hot water meets the preparation standard of general contrast agents, and preliminary dissolution and mixing are carried out in the mixing cup 2; Start the second motor 501 of the linkage mechanism 5 to drive the stirring rod 504 to stir in the mixing cup 2, and at the same time drive the cleaning mechanism 307 and the cooling mechanism 404 to brush down the remaining raw materials in the crushing cavity 301 for further crushing treatment, and at the same time cool the contrast agent; The second motor 501 synchronously drives the fan blade 503 to rotate. While further cooling the inside of the mixing cup 2, the mixing cup 2 gradually slides downward and squeezes the spring cup pad 601 to move downward. The gravity sensor 604 on the spring cup pad 601 synchronously starts the electric push rod 603 to slowly push the outer shell 1 upward, and finally the mixing cup 2 is separated from the bottom of the outer shell 1. The patient can remove the mixing cup 2 and take the prepared contrast agent for gastrointestinal ultrasound examination.
