Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a gastric tube anti-slip-off alarm device. Background Art

[0002] For some patients with severe illnesses, digestive tract dysfunction, and inability to eat through the mouth, clinical diet nursing measures will be taken according to the patient's condition to help the patient intake water and food. Among them, the common one is nasal feeding. Nasal feeding means that the gastric tube is first inserted into the esophagus through the nasal cavity, then the food is broken, and the food and water are transported into the patient's stomach through the gastric tube to maintain the body's functions. The commonly used gastric tube is prone to slipping off and causing discomfort to the patient. Reinserting the tube will increase the pain of the patient. At the same time, medical staff also have to constantly pay attention to whether the gastric tube has slipped off, which increases the work intensity of medical staff and reduces the work efficiency of medical personnel.

[0003] The specification of the Chinese invention patent application with the application publication number CN115737445A discloses an alarm system for preventing gastric tube from falling off. This alarm system for preventing gastric tube from falling off automatically alarms for the situation of gastric tube slipping off, reduces the labor intensity, and also uses the photoelectric principle to give a prompt for the risk of pipeline slipping off in time, and uses the upper clip assembly and the lower clip assembly to assist in fixing the gastric tube to prevent the pipeline from falling off. However, this alarm system for preventing gastric tube from falling off still has some disadvantages. For example: (1) The installation process is relatively complex, and it is inconvenient to operate by adjusting multiple components; (2) It is not easy to control the fixing force of the upper clip assembly and the lower clip assembly on the gastric tube. Being too tight or too loose may damage the gastric tube or the skin. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a gastric tube anti-slip-off alarm device, which can effectively solve the problem of gastric tube slipping off that may occur during the treatment of gastric tubes, real-time monitor the position of the gastric tube and give an alarm prompt, improve the safety and effect of gastric tube treatment, reduce the pain and risk of patients, and is convenient to use. The adopted technical scheme is as follows:

[0005] A gastric tube anti-slip-off alarm device, which is characterized by comprising a housing, a magnetic block, a detection and prompt device, and a magnetic sticker that can be attached to the outer wall of the gastric tube; a gastric tube passage for the gastric tube to pass through is provided on the housing; both the magnetic block and the detection and prompt device are arranged in the cavity of the housing; the detection and prompt device includes a Hall sensor, a control circuit, and an alarm prompt signal output device. The Hall sensor is electrically connected to the corresponding input end of the control circuit, and the alarm prompt signal output device is electrically connected to the corresponding output end of the control circuit.

[0006] In the above gastric tube anti-slip alarm device, the magnetic sticker is attached to the outer wall of the gastric tube, and its position on the gastric tube remains stable; the housing, the magnetic block and the detection and prompt device inside it are independent of the gastric tube as a whole and are fixed at a suitable position on the patient's body or the hospital bed. The gastric tube with the magnetic sticker passes through the gastric tube channel. The magnetic sticker can move together with the gastric tube. When the gastric tube moves, a magnetic field that moves together with the gastric tube is formed. When the gastric tube slips, the magnetic sticker moves accordingly, triggering the Hall sensor to generate a signal, which is conducted to the control circuit. The control circuit sends a control signal to the alarm prompt signal output device; at the same time, the magnetic sticker is adsorbed by the magnetic block, which can prevent the gastric tube from slipping further.

[0007] In the above detection and prompt device: The Hall sensor can sense the change of the magnetic field. When the gastric tube slips, the magnetic sticker moves with the gastric tube. The Hall sensor senses the change of the magnetic field intensity (usually when the magnetic sticker approaches the Hall sensor, the Hall sensor senses an increase in the magnetic field intensity), and sends a signal to the control circuit; the control circuit sends a control signal to the alarm prompt signal output device, so that the alarm prompt signal output device emits a prompt signal (such as a sound prompt signal, a light prompt signal), attracting the attention of the patient, medical staff or accompanying personnel, and prompting the patient, medical staff or accompanying personnel to handle the slipping problem.

[0008] Usually, after passing the gastric tube through the gastric tube channel, the magnetic sticker is attached to the outer wall of the gastric tube. The magnetic sticker is outside the gastric tube channel, and there is a certain distance between the magnetic sticker and the first end of the gastric tube channel. When the gastric tube slips, the distance between the magnetic sticker and the first end of the gastric tube channel decreases (the part of the gastric tube with the magnetic sticker can enter the gastric tube channel from the first end of the gastric tube channel), the distance between the magnetic sticker and the magnetic block decreases, and the distance between the magnetic sticker and the Hall sensor also decreases, so as to realize the magnetic adsorption between the magnetic sticker and the magnetic block, and trigger the Hall sensor. The first end of the gastric tube channel refers to the end of the gastric tube channel close to the patient's stomach along the extension direction of the gastric tube during use.

[0009] Usually, the positions of the magnetic block and the Hall sensor correspond to the gastric tube channel. In a preferred solution, both the magnetic block and the Hall sensor are arranged at positions close to the first end of the gastric tube channel.

[0010] Usually, the cross-section of the gastric tube channel is circular, and its inner diameter is slightly larger than the outer diameter of the gastric tube.

[0011] In a preferred solution, the above magnetic sticker includes a rubber magnet sheet, and an adhesive layer is provided on one side of the rubber magnet sheet. The rubber magnet sheet is soft and bendable, and is bonded to the outer wall of the gastric tube through the adhesive layer, so that the magnetic sticker is attached to the outer wall of the gastric tube.

[0012] Generally, the above magnetic blocks adopt strong magnets, such as neodymium iron boron magnets, so that small magnetic blocks have a large enough magnetic attraction force. When the gastric tube moves in the gastric tube channel, the magnetic sticker moves with the gastric tube; when the magnetic sticker approaches the magnetic block, the magnetic block adsorbs the magnetic sticker, which can prevent the gastric tube from slipping further.

[0013] The above alarm prompt signal output device can adopt a buzzer or a light emitting diode, or a combination of a buzzer and a light emitting diode. When the detection prompt device senses that the gastric tube has slipped, the buzzer can sound an alarm prompt, and the light emitting diode can emit light for alarm prompt. An out-sound hole can be provided at the position on the above shell corresponding to the buzzer.

[0014] The above detection prompt device also includes a battery for supplying power to the Hall sensor, the control circuit and the alarm prompt signal output device. The battery is installed in the cavity of the shell. The battery can adopt a lithium battery (such as a 3.7V lithium battery) or a dry battery.

[0015] The material of the above shell is determined by considering multiple factors such as strength, density, and hardness. Preferably, the material of the above shell is polyethylene plastic, which has the characteristics of low cost and stable structure in frequent sterilization cycles, and at the same time reduces the pressure feeling of the device on the patient.

[0016] The utility model can monitor the position of the gastric tube in real time and give an alarm prompt. When the gastric tube slips during the gastric tube treatment process, a prompt signal can be issued, and the gastric tube can be prevented from slipping further, improving the safety and effect of the gastric tube treatment, reducing the pain and risk of the patient, and thus effectively solving the problem of gastric tube slippage that may occur during the gastric tube treatment process; moreover, the structure of the utility model is relatively simple and easy to use.

[0021] Such as Figures 1 to 3As shown, this anti-displacement alarm device for gastric tubes includes a housing 1, a magnetic block 2, a detection and prompting device, and a magnetic sticker 4 that can be attached to the outer wall of the gastric tube 3; a gastric tube passage 5 for the gastric tube 3 to pass through is provided on the housing 1; both the magnetic block 2 and the detection and prompting device are arranged in the cavity of the housing 1; the detection and prompting device includes a Hall sensor 6, a control circuit 7, and an alarm prompt signal output device 8. The Hall sensor 6 is electrically connected to the corresponding input end of the control circuit 7, and the alarm prompt signal output device 8 is electrically connected to the corresponding output end of the control circuit 7. The positions of the magnetic block 2 and the Hall sensor 6 correspond to the gastric tube passage 5. In this embodiment, both the magnetic block 2 and the Hall sensor 6 are arranged at positions close to the first end 51 of the gastric tube passage.

[0022] In this embodiment, the cross-section of the gastric tube passage 5 is circular, and its inner diameter is slightly larger than the outer diameter of the gastric tube 3.

[0023] The magnetic sticker 4 includes a rubber magnet sheet, and an adhesive layer is provided on one side of the rubber magnet sheet. The rubber magnet sheet is bonded to the outer wall of the gastric tube 3 through the adhesive layer, so that the magnetic sticker is attached to the outer wall of the gastric tube.

[0024] The magnetic block 2 uses a strong magnet, such as a neodymium iron boron magnet.

[0025] In this embodiment, the alarm prompt signal output device 8 uses a buzzer. When the detection and prompting device senses the situation of the gastric tube slipping off, the buzzer can sound for alarm prompting. An sound outlet hole 10 can be provided at the position corresponding to the buzzer on the housing 1.

[0026] The detection and prompting device further includes a battery 9 for supplying power to the Hall sensor 6, the control circuit 7, and the alarm prompt signal output device 8. The battery 9 is installed in the cavity of the housing 1. In this embodiment, the battery 9 uses a lithium battery (such as a 3.7V lithium battery). Refer to Figure 4 , the control circuit 7 uses an ESP32-C3 Wi-Fi module; the 3.7v battery is connected to the 21st pin of the ESP32-C3 Wi-Fi module for power supply, and the ESP32-C3 Wi-Fi module supplies power to the Hall sensor 6 (U1CC6207MST) and the buzzer BUZZER1.

[0027] In this embodiment, the material of the housing 1 is polyethylene plastic. The housing 1 includes a housing main body 11 and a cover plate 12. An opening 13 is provided on the housing main body 11, and the cover plate 12 covers the opening 13.

[0028] The following briefly describes the usage method and working principle of the anti-displacement alarm device for gastric tubes in this embodiment:

[0029] During use, insert a gastric tube (while inserting the tube, the position of the gastric tube can be detected by using M-mode B-ultrasound) into the patient's body. After inserting the gastric tube, the part of the gastric tube outside the patient's body passes through the gastric tube channel 5, attach the magnetic sticker 4 to the outer wall of the gastric tube 3 outside the patient's body, and there is a certain distance between the magnetic sticker 4 and the first end 51 of the gastric tube channel; then place the housing 1 under the patient's mandible and fix its position.

[0030] When the gastric tube slips ( Figure 1 the arrow in

[0031] represents the moving direction of the gastric tube when it slips), the magnetic sticker 4 moves together with the gastric tube 3, and the distance between the magnetic sticker 4 and the first end 51 of the gastric tube channel decreases (the part of the gastric tube 3 with the magnetic sticker 4 can enter the gastric tube channel 5 from the first end 51 of the gastric tube channel), the distance between the magnetic sticker 4 and the magnetic block 2 decreases, and the distance between the magnetic sticker 4 and the Hall sensor 6 also decreases. When the magnetic sticker 4 moves with the gastric tube 3, a magnetic field that moves together with the gastric tube 3 is formed.

[0032] In the detection and prompting device, the Hall sensor 6 can sense the change of the magnetic field. When the magnetic sticker 4 moves with the gastric tube to a position close to the Hall sensor 6, the Hall sensor 6 senses the change of the magnetic field intensity and sends a signal to the control circuit 7; the control circuit 7 sends a control signal to the alarm prompting signal output device 8, so that the alarm prompting signal output device 8 issues a prompting signal to attract the attention of the patient, medical staff or accompanying personnel, and prompts the patient, medical staff or accompanying personnel to handle the problem of the gastric tube slipping. In this embodiment, the Hall sensor 6 senses a certain amount of magnetic field change, outputs a pulse signal to the ESP-32 WiFi module, changes the pin level connected to the buzzer, and triggers the buzzer to sound, prompting the patient, medical staff or accompanying personnel to handle the problem of the gastric tube slipping. At the same time, the magnetic sticker 4 approaches the magnetic block 2 and is adsorbed by the magnetic block 2, which can prevent the gastric tube 3 from slipping further, thereby avoiding the slippage of the gastric tube 3.

[0033] In other embodiments, the alarm prompting signal output device can also adopt a light-emitting diode, or a combination of a buzzer and a light-emitting diode.

[0034] In other embodiments, the battery can also adopt a dry battery.
