Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a multi-cavity fecal sampling device. Background Technology
[0002] Fecal collection equipment is a specialized tool used to collect and preserve fecal samples. It is mainly used for medical testing, scientific research and health monitoring. By detecting pathogens (such as bacteria and parasites), occult blood or abnormal cells in feces, it can help diagnose intestinal diseases. At the same time, epidemiological studies require a large number of standardized samples to analyze the patterns of disease transmission. Therefore, fecal collection is very important in many aspects.
[0003] The aforementioned fecal sampling equipment still has some problems in use. Traditional fecal sampling equipment is divided into solid fecal sampling equipment and liquid fecal sampling equipment. As the name suggests, different sampling equipment can only collect the corresponding type of feces. For example, solid fecal sampling equipment collects solid feces through a sampling spoon or sampling rod, while liquid fecal sampling equipment absorbs liquid feces through an air bag and a suction tube. However, in actual operation, it is impossible to determine whether the excreted feces are solid or liquid. If the sampling equipment is not compatible, it will affect the sampling work. The fecal sampling equipment has poor applicability. Therefore, a multi-chamber fecal sampling equipment is proposed to address the above problems. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, traditional fecal sampling equipment is divided into solid fecal sampling equipment and liquid fecal sampling equipment. As the names suggest, different sampling equipment can only collect the corresponding type of feces. For example, solid fecal sampling equipment collects solid feces using a sampling spoon or sampling rod, while liquid fecal sampling equipment absorbs liquid feces using an air bag and a suction tube. However, in actual operation, it is impossible to determine whether the excreted feces are solid or liquid. If the sampling equipment is not compatible, it will affect the sampling work. Fecal sampling equipment has the problem of poor applicability. This utility model proposes a multi-cavity fecal sampling device.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The multi-cavity fecal sampling device of this utility model includes a sampling cylinder, a guide rod is provided through the top of the sampling cylinder, and a suction head is fixedly connected to the bottom surface of the sampling cylinder. Several grooves are provided on the outer side of the bottom of the sampling cylinder. An air bladder is fixedly connected to the top of the guide rod, and a threaded disc is fixedly connected to the middle of the guide rod. An air pressure groove is opened inside the guide rod and communicates with the air bladder.
[0006] Preferably, the sampling tube has a threaded groove on the upper part of its interior, a threaded disc is located inside the threaded groove, and the threaded disc is threadedly connected to the threaded groove.
[0007] Preferably, the threaded disc has an L-shaped first air guide cavity inside, the horizontal position of the first air guide cavity is connected to the air pressure groove, and the vertical position of the first air guide cavity penetrates the top surface of the threaded disc.
[0008] Preferably, a set of second air guide chambers is provided on the side of the sampling cylinder, the bottom end of the second air guide chamber is connected to the groove, and the top end of the second air guide chamber is connected to the threaded groove.
[0009] Preferably, the bottom of the sampling tube has an L-shaped third air guide cavity on the inner side. The horizontal position of the third air guide cavity is connected to the interior of the sampling tube, and the vertical position of the third air guide cavity is connected to the suction head.
[0010] The advantages of this utility model are: 1. This utility model involves rotating a guide rod and a threaded disc. Since the threaded disc is threadedly connected to the threaded groove, the guide rod moves. When the guide rod moves downwards, the top surface of the threaded disc separates from the top surface of the threaded groove, opening the second air chamber and closing the third air chamber. Pressing the airbag causes the gas inside to escape from the groove. Then, the bottom of the sampling tube is inserted into the solid feces and rotated, allowing the solid feces to enter the groove. Releasing the airbag creates negative pressure inside the second air chamber, adsorbing the solid feces. The sampling tube is then removed and placed into a sealed bag, completing the solid feces sampling. Conversely, when the guide rod moves upwards, the top surface of the threaded disc separates from the top surface of the threaded groove. When the surfaces are in contact, the first and second air guide chambers are closed, while the third air guide chamber is open. Pressing the airbag causes the gas inside to be expelled from the suction head. Then, the bottom of the sampling tube is inserted into the solid feces. Releasing the airbag creates negative pressure inside the third air guide chamber, causing the liquid feces to be drawn in from the suction head and enter the sampling tube through the third air guide chamber. Afterward, the sampling tube is removed and placed inside a sealed bag, completing the sampling of the liquid feces. This application features an adjustable multi-chamber structure, which allows for adjustment of the sampling state of the sampling device, thereby enabling targeted collection of both solid and liquid feces, ensuring compatibility between the sampling device and the feces, and improving the applicability of the sampling device.

[0014] 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.
[0015] Please see Figure 1 one Figure 6 As shown, a multi-cavity fecal sampling device includes a sampling cylinder 1, a guide rod 2 is provided through the top of the sampling cylinder 1, and a suction head 3 is fixedly connected to the bottom surface of the sampling cylinder 1. Several grooves 4 are provided on the outer side of the bottom of the sampling cylinder 1. An air bladder 5 is fixedly connected to the top of the guide rod 2, and a threaded disc 6 is fixedly connected to the middle of the guide rod 2. An air pressure groove 8 is provided inside the guide rod 2 and is connected to the air bladder 5. During operation, traditional fecal sampling equipment is divided into solid fecal sampling equipment and liquid fecal sampling equipment. As the name suggests, different sampling equipment can only collect the corresponding type of feces. For example, solid fecal sampling equipment collects solid feces through a sampling spoon or sampling rod, while liquid fecal sampling equipment absorbs liquid feces through an air bag 5 and a suction tube. However, in actual operation, it is impossible to determine whether the excreted feces are solid or liquid. If the sampling equipment carried is not compatible, it will affect the sampling work. By moving the position of the guide rod 2, the sampling channel inside the sampling tube 1 is adjusted to form a solid-liquid dual chamber, thereby realizing the collection of dry and wet feces.
[0016] Furthermore, a threaded groove 7 is provided on the upper part of the interior of the sampling cylinder 1, and a threaded disc 6 is located inside the threaded groove 7, and the threaded disc 6 is threadedly connected to the threaded groove 7. When collecting solid feces during operation, the guide rod 2 and the threaded disc 6 are rotated counterclockwise. Since the threaded disc 6 is threadedly connected to the threaded groove 7, the guide rod 2 moves downward under the action of the threaded disc 6. The top surface of the threaded disc 6 separates from the top surface of the threaded groove 7, the second air guide chamber 10 is in the open state, and the third air guide chamber 11 is in the closed state.
[0017] Furthermore, the inside of the threaded disc 6 is provided with a set of L-shaped first air guide chambers 9. The horizontal position of the first air guide chambers 9 is connected to the air pressure groove 8, and the vertical position of the first air guide chambers 9 penetrates the top surface of the threaded disc 6. During operation, press the airbag 5. The gas inside the airbag 5 passes through the air pressure groove 8 and the first air guide chamber 9 and is discharged from the second air guide chamber 10. Then, insert the bottom of the sampling tube 1 into the solid feces and rotate it so that the solid feces enter the groove 4.
[0018] Furthermore, a set of second air guide chambers 10 are provided on the side of the sampling cylinder 1. The bottom end of the second air guide chamber 10 is connected through the groove 4, and the top end of the second air guide chamber 10 is connected through the threaded groove 7. During operation, the airbag 5 is released, creating negative pressure inside the second air chamber 10 to adsorb solid feces. Then, the sampling tube 1 is pulled out and placed inside the sealed bag to complete the sampling of solid feces.
[0019] Furthermore, a set of L-shaped third air guide chambers 11 are provided on the inner side of the bottom of the sampling tube 1. The horizontal position of the third air guide chamber 11 is connected to the interior of the sampling tube 1, and the vertical position of the third air guide chamber 11 is connected to the suction head 3. When collecting liquid feces during operation, rotate the guide rod 2 and the threaded disc 6 clockwise. At this time, the guide rod 2 moves upward under the action of the threaded disc 6, and the top surface of the threaded disc 6 fits against the top surface of the threaded groove 7. The first air guide chamber 9 and the second air guide chamber 10 are in a closed state, and the third air guide chamber 11 is in an open state. Press the air bag 5, and the gas inside the air bag 5 passes through the air pressure groove 8 and the third air guide chamber 11 and is discharged from the suction head 3. Then, insert the bottom of the sampling tube 1 into the solid feces, and then release the air bag 5. A negative pressure is generated inside the third air guide chamber 11, which causes the liquid feces to be sucked in from the suction head 3 and enter the sampling tube 1 through the third air guide chamber 11. After that, pull out the sampling tube 1 and put it into the sealed bag to complete the sampling of liquid feces.
[0020] Working principle: When solid feces need to be collected, rotate the guide rod 2 and the threaded disc 6 counterclockwise. Since the threaded disc 6 is threadedly connected to the threaded groove 7, the guide rod 2 moves downward under the action of the threaded disc 6. The top surface of the threaded disc 6 separates from the top surface of the threaded groove 7, the second air chamber 10 is in the open state, and the third air chamber 11 is in the closed state. Press the air bag 5, and the gas inside the air bag 5 passes through the air pressure groove 8 and the first air chamber 9 and is discharged from the second air chamber 10. Then, insert the bottom of the sampling tube 1 into the solid feces and rotate it. The solid feces enter the groove 4. Release the air bag 5, and a negative pressure is generated inside the second air chamber 10 to adsorb the solid feces. Then, pull out the sampling tube 1 and put it into the sealed bag to complete the solid feces sampling.
[0021] When liquid feces need to be collected, rotate the guide rod 2 and the threaded disc 6 clockwise. At this time, the guide rod 2 moves upward under the action of the threaded disc 6, and the top surface of the threaded disc 6 fits with the top surface of the threaded groove 7. The first air guide chamber 9 and the second air guide chamber 10 are in a closed state, and the third air guide chamber 11 is in an open state. Press the air bag 5, and the gas inside the air bag 5 passes through the air pressure groove 8 and the third air guide chamber 11 and is discharged from the suction head 3. Then, insert the bottom of the sampling tube 1 into the solid feces, and then release the air bag 5. A negative pressure is generated inside the third air guide chamber 11, which causes the liquid feces to be sucked in from the suction head 3 and enter the sampling tube 1 through the third air guide chamber 11. Then, pull out the sampling tube 1 and put it into the sealed bag to complete the sampling of liquid feces.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
