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 excrement, such as urine and feces.

[0003] When using an ostomy bag, the abdominal wall, intestinal cavity or urinary tract are less sensitive to pressure, so the patient needs to frequently observe the total volume of excrement in the ostomy bag to avoid "bag explosion". The so-called "bag explosion" means that the ostomy bag is too full, causing the ostomy bag to break and excrement to leak. The excrement from the intestinal fistula is not excreted into the ostomy bag at a steady rate, and the excretion rate varies greatly. To avoid "bag explosion", the patient needs to observe the total amount of the ostomy bag contents at any time, and deal with it in advance if the total amount is large.

[0004] Once the bag explodes, the excrement will stain the clothes, and the patient will feel very bad. When the patient is resting at home, he can put aside the clothes at any time to observe the total amount of the ostomy bag contents; when the patient is out, it is very inconvenient to observe the total amount of the contents for privacy protection; at the same time, if the patient is concentrating on doing things, he often ignores observing the ostomy bag.

[0005] In order to facilitate the observation of the total amount of contents in the ostomy bag, reduce the observation pressure on patients, and avoid bag explosion, there is an urgent need 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 make the technical solution of the present invention better understood by the technical personnel in the field, 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 the embodiments. The embodiments are only used to illustrate the present invention and are not used 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 excrement 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 the change of 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 the ostomy bag is similar to that of a conventional ostomy bag, so I will not go into details here.

[0041] In the early stage of use, the front and back walls of the ostomy bag are very close to each other. However, as the waste inside gradually increases, the front and back walls of the bag 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] Embodiment 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 wall and the outer wall gradually move away from each other, the magnetic field generator 2 and the magnetic field detector 3 also gradually move away from each other. During this process, the magnetic field intensity that can be detected by the magnetic field detector 3 also gradually decreases. When a certain critical value is reached, the magnetic field detector 3 sends information to the signal display 1, and the signal display 1 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. In order to ensure the accuracy of the detection, during the detection, the magnetic field strength of the magnetic field generator 2 must ensure that the magnetic field strength 20 mm away 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 the signal from the information transmitter, which is converted into the collection bag capacity information by the signal processor and displayed on the display screen. When the signal collected by the signal receiver is less than the set threshold, the alarm is triggered. The signal collected by the signal receiver is converted into substantial data, which is compared with the data of the set threshold. Once it 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 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 warns. The terminal of the information generation 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 generating system includes a magnetic field generating unit, a magnetic field strength detecting unit, an analog-to-digital conversion control unit, and an information sending unit, which correspond to a magnet, a magnetic field strength sensor, an information converter, and a wireless signal transmitter, respectively. That is, the terminal of the magnetic field generating unit is a magnetic field generator 2, which is a magnet or a magnet and is fixed to the solid side wall of the collection bag. The terminal of the magnetic field strength detecting unit is a magnetic field strength sensor. The magnetic field strength sensor can be a linear Hall sensor or a magnetoresistive sensor. In this embodiment, a linear Hall sensor is used, which is low in 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 the magnetic field generating unit moves away.

[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 the wireless signal from the information sending unit and converts it into an electrical signal and transmits it to the central control unit; the central control unit receives the electrical signal from the wireless signal receiving unit and controls the prompting unit through the electrical signal. When the wireless signal receiving unit receives the information from the information sending unit, the central control unit converts it into relevant capacity data and displays it on the display. Once it is less than the set threshold, the central control unit activates the alarm and the display screen also displays relevant information.

[0053] In order to ensure the function of the power supply, the information generation 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, and the second power supply 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 arranged on the outer side 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 will gradually bend and expand outward. The bending detection unit will gradually bend accordingly, and through the change in its own resistance, the internal capacity is indirectly measured.

[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 curvatures at both ends of the bending detection unit are 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 warns;

[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 for transmission 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 the curvature change of the surface of the collection bag itself is measured after the capacity changes.

[0062] 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 the wireless signal of the information sending unit, and converts it into an electrical signal and transmits it to the central control unit; the central control unit receives the electrical signal of the wireless signal receiving unit, and controls the prompting unit through the electrical signal. The relevant structural functions are the same as those in the above-mentioned embodiment 1, and are not described in detail here.

[0063] In the above two embodiments, the signal display 1 adopts a reminder bracelet, which is equipped with an information receiver, an alarm, a display screen and a signal processor. The signal processor adopts a single-chip microcomputer, which receives and converts the information of the information receiver and transmits it to the display screen. The signal processor controls the opening and closing of the alarm. After receiving the information of the wireless signal transmitter in the magnetic field detector 3, the alarm in the reminder bracelet emits an alarm sound and generates a certain vibration reminder by 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 familiar with the technology may modify or change the above embodiments without violating the spirit and scope of this patent application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in this patent application should still be covered by the claims of this patent application.
