Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a wireless collector which can be used for collecting the contents of the entire digestive tract. Background Art

[0002] Microorganisms exist in all aspects of the earth, and their relationship with the human body is inseparable. The human body's flora is widely distributed in the oral cavity, respiratory tract, intestines, skin and other tissues and organs, and participates in a variety of physiological metabolism and disease processes. Among the bacteria in the human body, the intestinal flora is the largest known micro-ecosystem in the human body, and plays an important role in human growth and development, endocrine, immune regulation, metabolism and other aspects. At the same time, studies have shown that the human intestinal flora is closely related to cardiovascular and cerebrovascular systems, respiratory systems, gastrointestinal systems, emotional diseases and many other diseases. At present, the research on intestinal flora is mainly based on the collection of fecal samples and the genetic sequencing of fecal samples. However, feces are excreted after food is digested by the gastrointestinal tract, and cannot fully reflect the flora of different segments of the digestive tract.

[0003] At present, relevant studies have been conducted to scientifically study and explore the above technical difficulties. One of the studies (PMID: 37165188) designed a capsule sampling device, which is composed of a hollow low-elasticity collection bag covered by a one-way valve. The bag is wrapped in a dissolvable capsule, and the surface of the capsule is coated with an enteric coating. The enteric coating will dissolve under certain pH conditions. When the capsule enters the intestine and reaches the target pH environment, the capsule will dissolve and the collection bag will unfold. Due to the effect of vacuum, the intestinal contents will be sucked into the bag along the one-way valve and discharged from the body with feces; another study (PMID: 35498852) designed a battery-free sampling capsule, which is composed of a 3D-printed acrylic shell, a hydrogel that quickly absorbs intestinal contents, and a flexible PDMS membrane. The capsule is coated with an enteric coating. When it reaches the intestine with the target pH value, the coating will dissolve, and the hydrogel in the capsule will swell and absorb the intestinal contents, and finally be discharged from the body with feces. Although the above studies collected intestinal contents through different methods, there are still some technical problems. First, both devices collect intestinal contents after the capsule is dissolved based on the intestinal pH value, so the intestinal location of the capsule cannot be determined; second, the collection process of both devices is passive collection, and the amount of contents collected by the capsule during the collection process cannot be ensured.

[0004] Capsule endoscopy, also known as capsule endoscope, is a capsule-shaped endoscope used to examine the human digestive tract. It is a medical device with the characteristics of non-invasive, continuous, visual, and no risk of cross infection. It can be swallowed with water and does not require anesthesia. Therefore, the patient compliance is high and it is suitable for a wide range of people. More importantly, the capsule endoscope can use the peristalsis of the human gastrointestinal tract to run along the stomach, duodenum, jejunum, ileum, colon, and rectum. At the same time, it can take pictures of the digestive tract it passes through, and transmit the images in real time with digital signals to the image recorder carried outside the patient for storage and recording, so as to observe the entire digestive tract of the human body. The whole process will last about 8 hours on average. At present, the clinical capsule endoscope is mainly based on observation, and it is impossible to perform endoscopic surgery or take biopsies of lesions like traditional endoscopes. At the same time, the current capsule endoscope can only take pictures at a fixed frame rate, and cannot continuously record, and can only store the images in the recorder carried outside the patient's body. Doctors cannot observe the patient's digestive tract in real time. Utility Model Content

[0034] Reference Figure 1-Figure 4As a specific embodiment of the utility model, the transparent optical end cover 8 is made of a polymer material that is conducive to the penetration of light from the micro camera 14 and cannot be decomposed by intestinal fluid; the transparent optical window cover is covered on the outer surface of the liquid storage groove of the shell 3, and is made of a polymer material that is conducive to the penetration of light and cannot be decomposed by intestinal fluid; the end cover 1, the shell 3, the camera base 7 and the rotating wheel shaft 6 are all made of a polymer material that cannot be decomposed by intestinal fluid through 3D printing; the first one-way valve 17 and the second one-way valve 5 are both made of natural rubber; the liquid storage groove and the shell 3 are made of the same material by 3D printing and are integrally formed, and are sterilized; the rotating wheel 5 is made of a polymer material that cannot be decomposed by intestinal fluid.

[0035] Reference Figure 4 As a specific embodiment of the utility model, the remote control switch 21 is used to start and stop the micro motor 20 according to the instruction of the computer; the power group 19 is used to provide the required power source for the wireless collector, which at least includes a power supply unit; the signal receiving and processing device 22 is used for the micro camera 14 to control the reception, processing and sending of signals; the micro camera 14 is used for the wireless collector to collect images of the inside of the intestine, and send the collected images to the signal receiving and processing device 22; the signal receiving and processing device 22 includes a signal wireless transmitter, a signal wireless receiver, an image sensor and an image processor.

[0036] Reference Figure 1 As a specific embodiment of the utility model, the total length of the wireless collector is smaller than the diameter of the intestine, and the outer diameter of the wireless collector is smaller than the diameter of the intestine.

[0037] Reference Figure 1-Figure 4 The workflow of the wireless collector for collecting the contents of the entire digestive tract inside the human intestine is as follows:

[0038] After the patient has completed the intestinal preparation, he orally takes the wireless collector under the guidance of the doctor. The wireless collector enters the intestine along the digestive tract and continues to move forward with the peristalsis of the intestine itself. During the moving process, the wireless collector uses a micro camera 14 (model: AV7.0; diameter 7.0mm) to continuously collect intestinal characteristic images and send the image signal to the signal receiving and processing device 22. The signal receiving and processing device 22 sends the processed signal to an external signal receiving box with wifi function, and the signal receiving box transmits the collected image to the computer.

[0039] When the wireless collector moves to the intestinal segment where the intestinal contents need to be collected, the doctor analyzes the collected lesion image and determines that there is a sufficient amount of intestinal contents near the wireless collector. Then, the doctor promptly sends an excitation signal to the remote control switch 21 through the microprocessor on the computer. When the remote control switch 21 receives the excitation signal, it controls the micro motor 20 (model: GB06-136-MD16001-1-M; diameter: 6.0mm; speed: 240 rpm) to move and work. The micro motor 20 drives the wheel 11 in the wheel cavity 23 to rotate through the wheel shaft 16. Figure 5 As shown, the principle of the flexible impeller pump is used, the runner 11 is made of flexible rubber, and the micro motor 20 drives the runner 11 to rotate eccentrically in the runner cavity 23 through the runner shaft 16. After the runner 11 rotates past the eccentric cam, the local space of the runner 11 is compressed and the volume is reduced. When the fluid passes through the runner cavity 23 and enters the inlet 24, the local volume of the runner 11 increases, forming a local vacuum, and the atmosphere presses the fluid into the cavity. When the cavity passes through the outlet tube, the volume of the cavity decreases, the fluid is squeezed out of the cavity and enters the outlet tube, and then enters the liquid inlet passage 9 through the outlet 25 on the wheel chamber 23, and flows to the liquid storage chamber 4 through the first one-way valve 17 connected to the liquid inlet passage 9, and the gas in the liquid storage chamber 4 is discharged from the gas outlet 6 through the second one-way valve 5, so that the intestinal contents are stored in the liquid storage chamber 4. When the liquid storage chamber 4 is full of intestinal contents, the doctor sends a stop signal to the remote control switch 21 through the microprocessor on the computer. After receiving the stop signal, the remote control switch 21 controls the micromotor 20 to stop working; at the same time, under the closing action of the first one-way valve 17 and the second one-way valve 5, the outflow of the intestinal contents in the liquid storage chamber 4 is blocked, thereby completing the collection of the contents of the target intestinal segment.

[0040] It can be seen from the above technical solutions that a wireless collector for collecting the contents of the entire digestive tract of the utility model can realize real-time viewing of the position of the wireless collector in the intestine and observation of the digestive tract conditions near the collector on the computer side through a micro camera 14 and a signal receiving and processing device 22, and complete the active collection and storage process of the intestinal contents using the liquid storage cavity 4 according to the digestive tract conditions.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
