Description

Technical Field

[0001] This utility model relates to the field of medical nebulization device technology, and in particular to an automatic nebulization stop device. Background Technology

[0002] Nebulization therapy mainly refers to aerosol inhalation therapy. Aerosols are tiny solid or liquid particles suspended in the air. Therefore, nebulization therapy uses a nebulizer to disperse medication into tiny droplets or particles, suspending them in a gas and allowing them to enter the respiratory tract and lungs, thereby humidifying the airways and treating respiratory inflammation.

[0003] During nebulizer therapy, medication is pressurized using a pressurizing device, causing it to pass through a nebulizer head and atomize into particles, which are then absorbed through the patient's breathing. However, when using a nebulizer, medical staff need to constantly monitor the dosage and promptly shut down the device after medication administration. This increases the workload and stress on medical staff.

[0004] Therefore, this application proposes an automatic shut-off device for nebulizing, which automatically shuts down the nebulizer after the nebulized medication is used up. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automatic nebulizer stop device to solve the problem mentioned in the prior art that the nebulized medicine cannot be automatically stopped after use.

[0006] To achieve the above and other related objectives, this utility model provides an automatic atomization stop device, including a covering device and an atomization detection device, wherein the atomization detection device is installed at the drug input end of the covering device;

[0007] The covering device includes a face mask, which is provided with a medicine nozzle and a ventilation hole, and both sides of the face mask are provided with fixing straps and connecting ears.

[0008] The atomization detection device includes a relay tube, an input connection tube at the bottom of the relay tube, an output connection tube on the side of the relay tube, the output connection tube is connected to the face mask, and the medicine nozzle is connected to the output connection tube.

[0009] A signal relay device is provided at the top of the relay tube, and a particle catcher is provided at the bottom of the signal relay device, with the particle catcher extending into the interior of the relay tube.

[0010] The particle trap is connected to a signal relay device, which can send commands outwards.

[0011] Preferably, the face mask is provided with a threaded connector, the medicine dispensing nozzle is located in the middle of the threaded connector, and the threaded connector is threadedly connected to the output connecting pipe.

[0012] Preferably, the signal relay device has an infrared sensor on the side facing the face mask, the infrared sensor is connected to the signal relay device, and the installation height of the infrared sensor is higher than the height of the face mask.

[0013] Preferably, the infrared sensor is one or a combination of a distance sensing device and a temperature sensing device.

[0014] Preferably, when the infrared sensor is a distance sensing device, the measurement distance is ±3cm from the infrared sensor to the front of the face mask.

[0015] Preferably, a power switch is provided on the top of the signal relay device, which can simultaneously control the particle trap and the infrared sensor.

[0016] Preferably, the outer surface of the signal relay device is provided with wiring ports and indicator lights.

[0017] Preferably, the relay tube is further provided with a one-way sealing ball and a sealing spring inside. The one-way sealing ball is located inside the relay tube near one end of the input connection tube, and the sealing spring is located between the particle catcher and the one-way sealing ball to apply pressure to the one-way sealing ball to seal the input connection tube.

[0018] Preferably, both the one-way sealing ball and the sealing spring are made of stainless steel, and the interior of the one-way sealing ball is hollow.

[0019] Preferably, the nozzle of the dispensing head faces the side inside the face mask.

[0020] As described above, the automatic atomization stop device of this utility model has the following beneficial effects:

[0021] 1. This utility model involves setting a relay tube on the back of the patch mask and connecting it to the drug delivery nozzle. At the same time, the relay tube is connected to the drug supply device through an input connecting pipe. During nebulization therapy, the drug will first pass through the inside of the relay tube and then enter the patch mask. At this time, the particle trap will detect the airflow. When no particles are detected in the gas, the particle trap will control the drug supply device to stop working through a wired or wireless control via a signal relay device, thereby achieving the effect of automatically stopping nebulization.

[0022] 2. This utility model installs an infrared sensor on a signal relay device to detect the patient and determine whether the patient is wearing a patch. When the patient cannot be detected, the infrared sensor transmits a stop command to the drug supply device through the signal relay device to avoid drug waste.

[0023] 3. This utility model improves hygiene and reduces equipment operating costs by setting a threaded connector on the face mask and connecting it to the output pipe. After use, the face mask can be removed and replaced as a disposable item.

[0024] 4. By placing the nozzle of the medicine dispensing head on the side, the atomized gas is sprayed out from the side to fill the interior of the mask, which can avoid the atomized gas being sprayed directly at the patient and improve the patient's comfort.

[0025] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0035] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0036] like Figures 1-3 As shown, this utility model provides an automatic nebulizer stop device, including a mask device 1 and a nebulization detection device 2. The mask device 1 is worn on the patient's face or airway opening. The nebulization detection device 2 is installed at the drug inlet of the mask device 1 and is also connected to an external drug delivery device. The drug delivery device pressurizes and nebulizes the drug, and transfers the nebulized drug to the nebulization detection device 2. The drug is then transferred back to the mask device 1 via the nebulization detection device 2. During the drug transfer process, the nebulization detection device 2 detects the gas to determine whether it contains the drug, and controls the operation of the drug delivery device based on the drug concentration.

[0037] Specifically, the mask device 1 includes a face mask 101, which is equipped with a drug dispensing nozzle 102 and a ventilation port 103. The drug dispensing nozzle 102 atomizes large drug particles into a fine mist under pressure, facilitating absorption by the patient. During breathing, the patient exchanges air with the outside environment through the ventilation port 103. Both sides of the face mask 101 have securing straps 104. Straps can be attached to the securing straps 104 to fix the face mask 101 to the patient's face or airway opening, improving ease of use.

[0038] The nebulization detection device 2 includes a relay tube 201. An input connection tube 202 is located at the bottom of the relay tube 201, connecting to a drug delivery device so that the nebulized medication can enter the interior of the face mask 101. An output connection tube 203 is located on the side of the relay tube 201, connecting to the face mask 101, and the drug delivery nozzle 102 is connected to the output connection tube 203. After entering the relay tube 201, the medication is further aspirated through the output connection tube 203 before entering the face mask 101 for absorption by the patient.

[0039] A signal relay device 204 is installed at the top of the relay tube 201. The signal relay device 204 contains a lithium battery and a signal transmission device, such as a Bluetooth device or a wireless signal transmitter, which connects to the drug supply device via signal matching. It can be powered and transmit signals via an external power supply or an external signal line. The specific power supply and signal transmission methods can be adjusted according to needs and manufacturing costs. A particle trap 205 is installed at the bottom of the signal relay device 204, extending into the interior of the relay tube 201. When the drug enters the relay tube 201, the particle trap 205 detects particles in the air. When the drug supply device is well-stocked, the air contains a large number of particles. Once the drug supply device is low on medication, the particle trap 205 cannot detect particles. The particle trap 205 is signal-connected to the signal relay device 204. When the particle trap 205 cannot detect drug particles, the signal relay device 204 sends a command to stop the drug supply device from operating. When the signal relay device 204 issues a shutdown command, it can send a notification to the server via the APP for medical staff to check.

[0040] like Figure 3 and Figure 4 As shown, in some embodiments, the patch mask 101 of this invention is provided with a threaded connector 105. The dispensing nozzle 102 is located in the middle of the threaded connector 105, and the threaded connector 105 is threadedly connected to the output connecting pipe 203. Through the threaded connection between the threaded connector 105 and the output connecting pipe 203, the patch mask 101 can be easily disassembled. After the patch mask 101 is used, the low-value patch mask 101 can be discarded, while the relatively high-value atomization detection device 2 can be reused repeatedly, reducing usage costs while maintaining hygiene.

[0041] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, an infrared sensor 206 is provided on the side of the signal relay device 204 facing the face mask 101. The infrared sensor 206 is used to detect the patient. The infrared sensor 206 is connected to the signal relay device 204, and its installation height is higher than that of the face mask 101. After the patient wears the face mask 101, the infrared sensor 206 senses the patient by distance or temperature. Once the patient removes the face mask 101, the infrared sensor 206 can detect this in time and transmit a signal to the signal relay device 204, causing the signal relay device 204 to issue a control command to the drug dispensing device to stop the machine, thus avoiding drug waste.

[0042] It is important to note that the infrared sensor 206 can be a distance sensor, a temperature sensor, or a combination thereof. When the infrared sensor 206 is used as a distance sensor, the distance between the infrared sensor 206 and the patient can be measured to determine whether the face mask 101 has been removed from the patient. When the infrared sensor 206 is used as a temperature sensor, the patient's body temperature can be measured to determine whether the face mask 101 has been removed from the patient. The accuracy is highest when both are used in combination. This avoids misjudging a patient wearing the face mask 101 when it is attached to an object. When the infrared sensor 206 is used as a distance sensor, the measurement distance is ±3cm from the front of the face mask 101 to the infrared sensor 206. The set positive and negative error distances are used to avoid misjudgments due to differences in the contours of the patient's face. This slightly reduces detection accuracy while improving the ease of use of the device.

[0043] like Figure 4 and Figure 5 As shown, in some embodiments, a power switch 207 is provided on the top of the signal relay device 204 of this utility model. The power switch 207 can simultaneously control the particle trap 205 and the infrared sensor 206. Before use, the particle trap 205 and the infrared sensor 206 are turned off by the power switch 207 to avoid misjudgment before the drug supply device has started supplying the drug, which would cause the drug supply device to malfunction. After the drug supply device supplies and atomizes the drug, the particle trap 205 and the infrared sensor 206 are turned on by the power switch 207 for detection.

[0044] like Figure 3 As shown, in some embodiments, the outer surface of the signal relay device 204 of this utility model is respectively provided with a wiring port 208 and an indicator light 209. The wiring port 208 is one of a power interface, a charging interface, or a data interface, depending on the power supply and signal transmission method. The indicator light 209 is used to indicate the working status of the signal relay device 204 and the lithium battery level. The indicator light 209 is a red-green dual-color LED, indicating different device states depending on the red and green display.

[0045] like Figure 3 As shown, in some embodiments, the relay tube 201 of this invention is further provided with a one-way sealing ball 210 and a sealing spring 211 inside. The one-way sealing ball 210 is located inside the relay tube 201 near the input connection tube 202, and the sealing spring 211 is located between the particle trap 205 and the one-way sealing ball 210, applying pressure to seal the input connection tube 202. When the drug supply device supplies drug to the relay tube 201, the relay tube 201 will compress the sealing spring 211 under pressure, thereby allowing the nebulized drug to enter the interior of the relay tube 201 through the input connection tube 202. When the drug supply device stops working, the pressure compressing the sealing spring 211 disappears, and the sealing spring 211 drives the one-way sealing ball 210 to seal the opening of the input connection tube 202 to prevent the patient's breathing gas from flowing back into the drug supply device.

[0046] It should be noted that both the one-way sealing ball 210 and the sealing spring 211 are made of stainless steel to prevent them from rusting due to corrosion from the drug. The interior of the one-way sealing ball 210 is hollow to reduce its weight, allowing the drug to compress the sealing spring 211 with only a small amount of pressure.

[0047] like Figure 5 As shown, in some embodiments, the nozzle of the drug dispensing head 102 of this invention faces the side inside the mask 101. The atomized drug diffuses through the nozzle 102 to all four sides inside the mask 101, avoiding direct impact of the drug on the patient's skin or airway opening, thus improving patient comfort. This is especially important after a patient's airway is accessed via a stoma, where direct airflow can cause significant discomfort.

[0048] The specific usage process of this utility model is as follows:

[0049] The relay tube 201 is connected to the dressing mask 101 by the output connecting tube 203 and the threaded connector 105. The dressing mask 101 is then worn on the patient's face or tracheostomy site. The relay tube 201 is connected to the drug delivery device by the input connecting tube 202 and the tubing. The signal is matched with the drug delivery device by the signal relay device 204.

[0050] Turn off the particle trap 205 and infrared sensor 206 by turning off the power switch 207, and then start the drug supply device to atomize and deliver the drug. After a short while, turn on the particle trap 205 and infrared sensor 206 by turning on the power switch 207 to detect the patient and the drug.

[0051] When the particle catcher 205 fails to detect drug particles, it will send a shutdown command to the drug supply device through the signal relay device 204. When the infrared sensor 206 loses the patient target, it will send a shutdown command to the drug supply device through the signal relay device 204.

[0052] In summary, the automatic nebulization stop device of this utility model, by setting a relay tube 201 on the back of the application mask 101 and connecting it to the drug dispensing nozzle 102, and simultaneously connecting the relay tube 201 to the drug supply device through the input connecting pipe 202, when performing nebulization therapy, the drug will first pass through the inside of the relay tube 201 and then enter the application mask 101. At this time, the particle trap 205 will detect the airflow. When no particles are detected in the gas, the particle trap 205 controls the drug supply device to stop working through the signal relay device 204 in a wired or wireless manner, thereby achieving the effect of automatically stopping nebulization.

[0053] This invention installs an infrared sensor 206 on a signal relay device 204 and uses the infrared sensor 206 to detect the patient to determine whether the patient is wearing the patch mask 101. When the patient cannot be detected, the infrared sensor 206 transmits a stop command to the drug supply device through the signal relay device 204 to avoid drug waste.

[0054] This invention improves hygiene and reduces equipment operating costs by providing a threaded connector 105 on the face mask 101 and connecting it to the output connecting pipe 203 via the threaded connector 105. After use, the face mask 101 can be disassembled and replaced as a disposable item.

[0055] This invention, by placing the nozzle of the dispensing head 102 on the side, allows the atomized gas to be sprayed out from the side and fill the interior of the mask 101, thus avoiding the atomized gas being sprayed directly onto the patient and improving the patient's comfort.

[0056] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0057] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
