Abstract
Description
Technical Field
[0001] The present invention mainly relates to the field of medical devices, and in particular to an ostomy bag and a capacity detection system thereof. Background Art
[0002] An ostomy bag is a medical device used to connect to the stoma on the abdominal wall to store the patient's excretions, such as urine and feces.
[0003] When using an ostomy bag, patients should constantly monitor the total volume of fecal material in the bag to prevent a "bag burst," as the abdominal wall, intestinal cavity, and urinary tract are less sensitive to pressure. A "bag burst" occurs when the bag is overfilled, causing it to break and leak. Enterostomy fluid does not drain into the bag at a steady rate; its rate of discharge varies widely. To prevent a "bag burst," patients should constantly monitor the total volume of their bag and, if it is high, preemptively dispose of it.
[0004] Once the bag explodes, the excrement stains clothing, causing the patient to feel extremely uncomfortable. When the patient is resting at home, they can always put aside their clothes and check the total amount of the ostomy bag contents. However, when the patient is out and about, it is extremely inconvenient to check the total amount of the contents for privacy reasons. At the same time, if the patient is focused on doing something, they often forget to check the ostomy bag.
[0005] In order to facilitate the observation of the total amount of contents in the ostomy bag, reduce the patient's observation pressure, and avoid the bag from exploding, there is an urgent need in the clinic for a product that can transmit the total amount of contents in the ostomy bag to the patient at any time for easy observation; and alarm before the "bag explodes", so that the patient has enough time to deal with it.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention and to make the above-mentioned features, purposes and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with examples. The examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0036] like Figure 1-3 As shown, the present invention includes: an ostomy bag and a capacity detection system thereof.
[0037] The pocket includes a collection bag for collecting stoma excreta and a signal display 1 for displaying the capacity status of the collection bag; the collection bag includes an inner wall adjacent to the skin and a corresponding outer wall; the side wall of the collection bag is provided with an information collector for sensing changes in the collection bag capacity and an information transmitter for transmitting information from the information collector;
[0038] The information collector includes a magnetic field information collector or a bending sensor arranged on the outer side wall of the collection bag;
[0039] The signal display 1 transmits information with the information transmitter via wireless signals and displays capacity information.
[0040] The use of ostomy bags is similar to that of conventional ostomy bags, so I will not go into details here.
[0041] In the early stages of ostomy bag use, the front and back walls are very close to each other. However, as the amount of waste inside gradually increases, the front and back walls gradually move away from each other.
[0042] During this process, the inner wall adjacent to the skin and the corresponding outer wall will gradually move away from each other, and synchronously, the outer wall will gradually bend and expand outward.
[0043] Based on the above changes, the capacity change of the collection bag can be indirectly measured by the information collector, and finally the information is transmitted to the signal display 1 for display by the information transmitter.
[0044] Example 1: In the above, the information collector adopts a magnetic field information collector, which includes a magnetic field generator 2 and a magnetic field detector 3; the magnetic field generator 2 is arranged on one side wall of the collection bag, and the magnetic field detector 3 is arranged on the corresponding area of the other side wall of the collection bag; the magnetic field detector 3 includes a magnetic field intensity sensor
[0045] As the inner and outer walls gradually move away from each other, magnetic field generator 2 and magnetic field detector 3 also gradually move away. During this process, the magnetic field intensity detected by magnetic field detector 3 gradually decreases. When it reaches a certain critical value, magnetic field detector 3 sends a message to signal display 1, which issues a warning.
[0046] In actual use, the critical distance between the magnetic field generator 2 and the magnetic field detector 3 is generally 10 cm, and the warning distance is 5 cm. To ensure the accuracy of the detection, the magnetic field strength of the magnetic field generator 2 must ensure that the magnetic field strength at a distance of 20 mm from the magnet surface is greater than 100 Gs.
[0047] The signal display 1 includes a signal receiver, a signal processor, a display screen, and an alarm. The signal receiver receives a signal from an information transmitter, which is converted by the signal processor into bag capacity information, which is then displayed on the display screen. If the signal collected by the signal receiver is less than a set threshold, the alarm is triggered. The signal collected by the signal receiver is converted into actual data and compared with the set threshold. If the data is less than the set threshold, the alarm is triggered.
[0048] refer to Figure 4 , the capacity detection system corresponding to the above-mentioned ostomy bag structure is as follows:
[0049] It includes an information generating system and an information receiving and processing system. The information receiving and processing system receives information from the information generating system and displays and warns. The terminal of the information generating system is a magnetic field information collector, and the terminal of the information receiving and processing system is a signal display 1.
[0050] The information generation system includes a magnetic field generating unit, a magnetic field intensity detection unit, an analog-to-digital conversion control unit, and an information transmission unit, corresponding to the magnet, magnetic field intensity sensor, information converter, and wireless signal transmitter, respectively. Specifically, the magnetic field generating unit terminates at a magnetic field generator 2, which utilizes a magnet and is fixed to the solid sidewall of the collection bag. The magnetic field intensity detection unit terminates at a magnetic field intensity sensor. The magnetic field intensity sensor can be a linear Hall effect sensor or a magnetoresistive sensor. In this embodiment, a linear Hall effect sensor is used due to its low cost.
[0051] The magnetic field strength detection unit detects the magnetic field strength of the magnetic field generating unit and converts it into an electrical signal and transmits it to the analog-to-digital conversion control unit; the analog-to-digital conversion control unit converts the electrical signal of the magnetic field strength detection unit and transmits it to the information sending unit; the information sending unit receives the electrical signal from the analog-to-digital conversion control unit and converts it into a wireless signal; the magnetic field strength received by the magnetic field strength detection unit will gradually decrease as it moves away from the magnetic field generating unit.
[0052] The information receiving and processing system includes a wireless signal receiving unit, a central control unit, and a prompting unit. The wireless signal receiving unit receives wireless signals from the information sending unit and converts them into electrical signals for transmission to the central control unit. The central control unit receives electrical signals from the wireless signal receiving unit and controls the prompting unit via these signals. When the wireless signal receiving unit receives information from the information sending unit, the central control unit converts it into relevant capacity data and displays it on a display. If the data falls below a set threshold, the central control unit activates an alarm and displays relevant information on the display.
[0053] In order to ensure the function of the power supply, the information generating system is provided with a built-in power supply, which supplies power to the magnetic field strength detection unit, the analog-to-digital conversion control unit and the information sending unit. The built-in power supply uses a replaceable battery.
[0054] The information receiving and processing system is provided with a second power supply, which supplies power to the wireless signal receiving unit, the central control unit and the prompting unit. The second power supply is a rechargeable power supply.
[0055] Embodiment 2: Different from embodiment 1, the information collector uses a bending sensor disposed on the outer wall of the collection bag. The bending detection unit includes a flexible resistive bending sensor.
[0056] The principle is that as the amount of waste in the bag increases, the outer wall gradually bends and expands outwards. The bending detection unit will gradually bend accordingly, and through the change in its own resistance, it indirectly measures the internal capacity.
[0057] In actual use, the critical distance between the inner wall and the outer wall is generally 10 cm, and the warning distance is 5 cm. The corresponding curvature of the two ends of the bending detection unit is greater than 0.8.
[0058] refer to Figure 5 , the capacity detection system corresponding to the above-mentioned ostomy bag structure is as follows:
[0059] It includes an information generation system and an information receiving and processing system. The information receiving and processing system receives information from the information generation system and displays and issues warnings.
[0060] The information generating system includes a bending detection unit, an analog-to-digital conversion control unit, and an information sending unit.
[0061] The bending detection unit detects the change of its own curvature through the change of resistance, and converts it into an electrical signal and transmits it to the analog-to-digital conversion control unit; the analog-to-digital conversion control unit converts the electrical signal of the bending detection unit and transmits it to the information sending unit; the information sending unit receives the electrical signal from the analog-to-digital conversion control unit and converts it into a wireless signal; the difference from the above embodiment is that the capacity information is not collected through the change of magnetic field, but is measured by the change of curvature of the surface of the collection bag itself after the capacity changes.
[0062] The information receiving and processing system includes a wireless signal receiving unit, a central control unit, and a prompt unit. The wireless signal receiving unit receives wireless signals from the information sending unit and converts them into electrical signals for transmission to the central control unit. The central control unit receives electrical signals from the wireless signal receiving unit and controls the prompt unit via the electrical signals. The relevant structures and functions are the same as those in the first embodiment above and are not further described here.
[0063] In the two aforementioned embodiments, the signal display 1 is a reminder bracelet with a built-in information receiver, alarm, display, and signal processor. The signal processor, a single-chip microcomputer, receives and converts information from the information receiver and transmits it to the display. The signal processor controls the activation and deactivation of the alarm. Upon receiving information from the wireless signal transmitter in the magnetic field detector 3, the alarm in the reminder bracelet sounds an alarm and generates a certain vibration reminder through sound waves.
[0064] The above embodiments are merely illustrative of the principles and effects of this patent application and are not intended to limit this patent application. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this patent application. Therefore, all equivalent modifications or alterations made by persons of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this patent application shall be covered by the claims of this patent application.
