Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an ear, nose and throat medication device. Background Art

[0002] In the treatment of ENT diseases, drug administration is one of the important treatment methods. Traditional ENT drug delivery devices mostly use simple drip or syringe push methods. However, traditional ENT drug delivery devices have many shortcomings:

[0003] First, most devices use fixed-specification probes that cannot adapt to the individual differences in the physiological structure of the nasal cavity and ear canal of different patients. For example, the width of the nasal cavity of a child is only 2-4mm, while that of an adult can reach 5-8mm. When using a probe of the same specification, it will not only cause pain to the patient, but also easily lead to leakage of the drug solution, affecting the treatment effect. Patients of different age groups and physical conditions have significant differences in the size and shape of their ear, nose and throat cavities. Fixed-specification probes are difficult to meet diverse clinical needs.

[0004] Secondly, with common nasal drop bottles, medical staff or patients must manually control the bottle's tilt angle and drip rate, making it difficult to precisely control the dosage. In practice, this can easily lead to excessive dripping, resulting in wasted liquid and discomfort in the throat, or insufficient dripping, resulting in ineffective treatment. Furthermore, manual control of drip rate and dosage is significantly affected by human factors, and variability between operators can lead to varying drug delivery outcomes.

[0005] When using a syringe to push the drug, not only is the operation more cumbersome, it requires medical staff to have certain operating skills and experience. In addition, due to the fixed structure of the syringe, it is difficult to adapt to the shape and size differences of the ear, nose and throat cavities of different patients when inserted into the patient's cavity, which may cause damage to the patient's cavity. At the same time, during the drug administration process, medical staff cannot accurately observe the internal conditions of the cavity, which can easily lead to inaccurate drug administration positions and affect the treatment effect. For example, when administering drugs to the nasal cavity, if the drug administration position is not accurate, the drug solution may not reach the lesion site, and thus cannot play its due therapeutic role.

[0006] Therefore, in order to solve the above problems, the present invention provides an ear, nose and throat medication device. Summary of the Invention

[0007] To solve the above problems, the present invention provides an ENT drug delivery device for accurately, safely and efficiently delivering liquid medicine to the lesion site of the patient's ENT, nose and throat, overcoming the many defects of traditional drug delivery devices, improving the treatment effect and reducing the patient's discomfort.

[0015] Furthermore, a medicine liquid temperature regulating component is installed on the outside of the medicine storage cavity, and the medicine liquid temperature regulating component includes a semiconductor refrigeration plate, a heating wire and a temperature sensor; the temperature sensor is used to monitor the temperature of the medicine liquid in the medicine storage cavity in real time; when the medicine liquid temperature monitored in real time by the temperature sensor exceeds or is lower than the temperature threshold preset in the controller, the controller controls the semiconductor refrigeration plate or the heating wire to work.

The pressure sensor, image sensor and infrared sensor are all installed at the front end of the probe, and the pressure sensor, image sensor and infrared sensor are all connected to the controller signal.

[0017] Furthermore, it also includes an early warning component, which includes a buzzer and an indicator light, both of which are connected to the controller signal; when the pressure monitored by the pressure sensor exceeds the safety pressure threshold preset in the controller, the controller controls the buzzer to emit an alarm sound, and the indicator light flashes at the same time to remind medical staff; when the image sensor detects an abnormal lesion area inside the patient's ear, nose and throat cavity, the controller controls the indicator light to flash at a specific frequency to remind medical staff; when the temperature detected by the infrared sensor exceeds or is lower than the normal body temperature range, the controller controls the buzzer to emit alarm sounds of different frequencies, and the indicator light displays different colors to remind medical staff and patients.

[0018] Furthermore, a hardness adjustment component is provided on the drug delivery hose, which includes several air bags and an air pump distributed along the length of the drug delivery hose.

[0020] The above scheme has the following beneficial effects:

[0021] 1. This solution uses a connector consisting of an inner ball cage, an outer ball cage, and a transmission steel ball. Compared with traditional fixed-angle probes, this solution can achieve flexible adjustment at multiple angles. It can accurately adapt to the complex ear, nose, and throat cavity structures of different patients, effectively avoiding drug delivery blind spots or mucosal damage caused by improper probe angles, and greatly improving the applicability and ease of operation of the device.

[0022] 2. This solution adopts a linkage adjustment component consisting of a rotary adjustment part, a first transmission unit and a second transmission unit. Compared with the traditional method of independently adjusting the drug delivery volume and the probe angle, the coordinated control of the drug delivery volume and the probe angle can be achieved through a single knob handle combined with a switching lever, which simplifies the operation process, significantly reduces the operation difficulty and time cost of medical staff, and improves drug delivery efficiency.

[0023] 3. In this solution, the piston and the screw form a ball screw structure, which is combined with a guide assembly. Compared with the traditional ordinary screw transmission method, it has higher transmission accuracy and smaller friction resistance, and can achieve precise control of the amount of drug liquid pushed, avoiding dosage errors caused by uneven manual injection force. It is especially suitable for children and special patient groups who have high requirements for drug delivery accuracy, ensuring the treatment effect.

[0024] 4. This solution sets a retractable support arm and an elastic reset part in the probe, and links it with the second transmission unit. Compared with the traditional single-specification probe, it can adapt to the cavity size of different patients while adjusting the probe angle, so that the probe fits tightly with the inner wall of the cavity, effectively preventing the side leakage of the drug solution, and at the same time reducing the patient's discomfort caused by the inappropriate probe size.

[0025] 5. This solution uses a liquid medicine temperature regulating component to monitor and adjust the liquid medicine temperature in real time. Compared with traditional drug delivery devices that do not consider the liquid medicine temperature, this solution can accurately control the liquid medicine temperature within the suitable range for the human body, avoiding irritation to the patient's cavity mucosa due to overcooling or overheating of the liquid medicine, thereby improving the patient's treatment comfort and safety.

[0026] 6. This solution integrates monitoring components such as pressure sensors, image sensors and infrared sensors, and cooperates with early warning components. Compared with traditional drug delivery devices that lack real-time monitoring, it can obtain all-round real-time information such as pressure, image and temperature in the patient's cavity, and issue alarms in time to indicate abnormal conditions, so that medical staff can adjust operation strategies in time, reduce medical risks, and improve the accuracy and safety of diagnosis and treatment.

[0027] 7. This solution sets a hardness adjustment component on the drug delivery hose. Compared with the traditional drug delivery hose with fixed hardness, the hardness of the hose can be dynamically adjusted according to the patient's cavity information. In complex cavities, it can not only ensure the flexibility of the hose for smooth penetration, but also provide sufficient support when needed to avoid excessive bending of the hose affecting drug delivery, while reducing the risk of damage to the inner wall of the cavity, thereby improving the safety and effectiveness of drug delivery.

[0039] The following is further described in detail through specific implementation methods:

[0040] Example 1:

[0041] As attached Figures 1 to 5 The figure shows an ENT medication delivery device, comprising a housing 1, within which is disposed a medicine storage chamber 2 for storing liquid medicine. A handle 101 is provided at the bottom of the housing 1. The top of the medicine storage chamber 2 is provided with a liquid injection port and a cover for sealing the injection port. A transparent observation window is provided next to the injection port for viewing the remaining liquid medicine. The observation window is provided with graduated lines, allowing medical personnel to intuitively understand the remaining liquid medicine in the medicine storage chamber 2. The medicine storage chamber 2 is connected to a medicine delivery hose 3 for delivering the medicine to the lesion site. A medicine delivery control component for controlling the amount of medicine delivered is installed in the medicine storage chamber 2. A probe 4 for contacting the patient's ENT cavity and guiding the medicine is installed at one end of the medicine delivery hose 3 away from the medicine storage chamber 2. A connector for adjusting the angle of the probe 4 is installed between the probe 4 and the medicine delivery hose 3. The connector includes an inner ball cage 5 and an outer ball cage 6. The outer ball cage 6 is fixedly connected to the probe 4. The end of the medicine delivery hose 3 away from the medicine storage chamber 2 passes through the inner ball cage 5 and is connected to the probe 4. A plurality of slide grooves 7 are respectively provided on the inner ball cage 5 and the outer ball cage 6. A transmission steel ball 8 is rollingly fitted in the slide groove 7. The transmission steel ball 8 is outer-mounted with a retaining frame 9. The retaining frame 9 is used to keep the transmission steel ball 8 at the intersection of the slide grooves 7 of the inner ball cage 5 and the outer ball cage 6 (such as Figure 4 and Figure 5 shown).

[0042] A linkage adjustment assembly is mounted outside the medicine storage chamber 2. The assembly comprises a rotary adjustment member, a first transmission unit, and a second transmission unit. The rotary adjustment member is connected to the medication delivery control assembly via the first transmission unit for adjusting the volume of medication delivered. The rotary adjustment member is connected to the inner cage 5 via the second transmission unit for adjusting the angle of the probe 4. The rotary adjustment member comprises a knob handle 10, rotatably mounted outside the medicine storage chamber 2. A switching lever 11 is located within the knob handle 10, which switches the operating states of the first and second transmission units. An angle scale ring and a dosage scale ring are located on the top wall of the medicine storage chamber 2, located outside the knob handle 10.

[0043] The first transmission unit includes a driving gear 12 and a driven gear 13. The driving gear 12 is fixedly mounted on the rotating shaft of the rotating handle. The driven gear 13 is coaxially fixedly connected to a screw 14. A limiting ring 19 is provided on the end of the screw 14 away from the driven gear 13. The limiting ring 19 is fixedly connected to the inner wall of the medicine storage chamber 2. The screw 14 is threadedly fitted with a piston 15 for pushing the liquid medicine. The piston 15 and the screw 14 form a ball screw structure. The drug administration control assembly includes a guide assembly, which includes a guide groove 16. A guide block 17 is slidably fitted on the guide groove 16. The guide block 17 is fixedly connected to the outer wall of the piston 15 (such as Figure 3 shown).

[0044] The second transmission unit includes a power element. In this embodiment, the power element is a micro-electric cylinder mounted on the inner wall of the outer cage 6. The output shaft of the power element is coaxially fixedly connected to a rack, which meshes with a gear ring. The gear ring is fixedly connected to the bottom of the inner cage 5. The power element is connected to the controller for signal transmission, and the controller is connected to the proximity switch 18, which is mounted on the outside of the switching lever 11 and the drug storage chamber 2. A power module is also included to supply power to the power element (not shown).

[0045] The probe 4 includes a flexible silicone sleeve and an elastic support frame, which is provided with a number of retractable support arms distributed along the circumferential direction; an elastic reset member (not shown in the figure) is connected between the retractable support arm and the inner wall of the probe 4; the second transmission unit is also connected to the retractable support arm through a rack, and while adjusting the angle of the probe 4, the retractable support arm is synchronously driven to retract, so that the probe 4 can adapt to the cavity size of different patients.

[0046] The specific implementation process is as follows: before using the ear-nose-throat administration device, the medical staff first checks the transparent observation window and scale line at the top of the medicine storage cavity 2 to confirm the remaining amount of liquid medicine in the medicine storage cavity 2. If the liquid medicine is insufficient, the liquid medicine preparation work needs to be carried out: first, use medical alcohol to disinfect the liquid injection port and its surrounding area, open the cover of the liquid injection port, and inject the appropriate amount of liquid medicine meeting the treatment requirements into the medicine storage cavity 2 through the liquid injection port. After the injection is completed, the cover is tightly screwed on the liquid injection port to ensure the sealing of the medicine storage cavity 2. When injecting the liquid medicine, the medical staff should strictly follow the aseptic operation specification to prevent the liquid medicine from being contaminated.

[0047] When the patient needs to be administered, the medical staff holds the administration device and slowly inserts the probe 4 into the ear-nose-throat cavity of the patient. Due to the differences in the size and shape of the ear-nose-throat cavities of different patients, the knob handle 10 is rotated at this time, the switching lever 11 inside the knob handle 10 moves, the proximity switch 18 is triggered, the proximity switch 18 transmits a signal to the controller, and the controller starts the micro-cylinder of the second transmission unit. The output shaft of the micro-cylinder drives the rack to move linearly, the rack is engaged with the gear ring, thereby driving the inner ball cage 5 to rotate relative to the outer ball cage 6, and the angle of the probe 4 is adjusted; at the same time, the rack drives the telescopic support arm to extend and retract through the transmission connecting rod, and the elastic return member assists the extension and retraction of the support arm, so that the probe 4 can adapt to the cavity size of different patients, ensure that the probe 4 is tightly fitted with the inner wall of the cavity, and reduce the possibility of side leakage of the liquid medicine. In this process, the medical staff can accurately control the deflection angle of the probe 4 by observing the angle scale ring on the surface of the knob handle 10.

[0048] When the probe 4 is adjusted to the appropriate angle and position, the medical staff operates the knob handle 10 again, and the switching lever 11 switches the transmission path to the first transmission unit. Continue to rotate the knob handle 10, the rotating shaft of the knob handle 10 drives the driving gear 12 to rotate, the driving gear 12 is engaged with the driven gear 13, and the driven gear 13 coaxially fixedly connected with the screw rod 14 rotates. Since the screw rod 14 and the piston 15 form a ball screw structure, the rotation of the screw rod 14 is converted into the linear motion of the piston 15 along the axial direction, and under the limitation of the guide groove 16 and the guide block 17 of the guide assembly, the piston 15 can only move smoothly along the axial direction of the screw rod 14, thereby accurately controlling the pushing amount of the liquid medicine. The medical staff can accurately read the pushing amount of the liquid medicine through the dose scale ring on the surface of the knob handle 10 to ensure the accuracy of the administration operation.

[0049] After adjusting the delivery volume, the drug delivery device is activated. Driven by piston 15, the drug in reservoir 2 is delivered to probe 4 via drug delivery hose 3. Probe 4 then directs the drug to the affected area, completing the drug delivery process. During the drug delivery process, medical staff should closely monitor the changes in the remaining drug volume in the transparent observation window, the patient's response, and the value on the dose scale. They should flexibly adjust the delivery volume based on the treatment progress and the patient's actual needs. If the patient experiences any discomfort, drug delivery should be stopped immediately and appropriate treatment measures should be taken.

[0050] After the drug administration operation is completed, remove the probe 4 from the patient's cavity and strictly clean and disinfect the probe 4, drug administration hose 3, and other components that come into contact with the drug solution or the patient's cavity. Use a dedicated medical detergent for cleaning. Disinfection can be done by high-temperature sterilization, chemical disinfection, or other methods that meet medical standards. After processing, store the device properly for future use. Turn off the drug administration device, reset the knob handle 10, and disconnect the power module to ensure that the device is in a safe state. At the same time, perform an appearance inspection and functional test on the entire device. If any abnormality is found, repair or replace the component in a timely manner.

[0051] Example 2:

[0052] As attached Figure 6 As shown, the difference from Example 1 is that a medicine liquid temperature regulating component is installed on the outside of the medicine storage cavity 2, and the medicine liquid temperature regulating component includes a semiconductor refrigeration plate, a heating wire and a temperature sensor; the temperature sensor is used to monitor the temperature of the medicine liquid in the medicine storage cavity 2 in real time; when the medicine liquid temperature monitored in real time by the temperature sensor exceeds or is lower than the temperature threshold preset in the controller, the controller controls the semiconductor refrigeration plate or the heating wire to work.

[0053] The specific implementation process is as follows: Medical staff need to pre-set the appropriate temperature threshold of the liquid medicine in the controller (generally 36℃-37℃). When injecting the liquid medicine, medical staff should strictly follow the aseptic operation specifications to prevent the liquid medicine from being contaminated. At the same time, medical staff need to pre-set the appropriate temperature threshold of the liquid medicine in the controller. Generally, the temperature of the liquid medicine for ENT administration is kept at 36℃-37℃, which is close to human body temperature. This temperature range can not only prevent patients from feeling uncomfortable due to overcooling or overheating of the liquid medicine, but also help the liquid medicine to better exert its therapeutic effect.

[0054] After the liquid medicine is added, the temperature sensor begins to monitor the liquid medicine temperature in the liquid medicine storage chamber 2 in real time and transmits the monitoring data to the controller in real time. If the liquid medicine temperature detected by the temperature sensor exceeds or falls below the preset temperature threshold, the controller automatically responds based on the temperature deviation: when the liquid medicine temperature is higher than the preset upper limit, the controller activates the semiconductor cooling plate, which absorbs heat from the liquid medicine storage chamber 2 through the Peltier effect and cools the liquid medicine; when the liquid medicine temperature is lower than the preset lower limit, the controller activates the heating wire, which generates heat through the current and heats the liquid medicine. During the temperature adjustment process, the temperature sensor continuously monitors the temperature changes of the liquid medicine and feeds the data back to the controller. The controller dynamically adjusts the operating power of the semiconductor cooling plate or heating wire based on the feedback information until the liquid medicine temperature reaches the preset temperature threshold range.

[0055] Example 3:

[0056] As attached Figure 6 As shown, the difference from Example 2 is that it also includes a monitoring component, which includes a pressure sensor, an image sensor and an infrared sensor. The pressure sensor is used to monitor the pressure when the probe 4 contacts the patient's ENT cavity in real time, the image sensor is used to obtain image information inside the patient's ENT cavity, and the infrared sensor is used to detect the temperature information inside the patient's ENT cavity. The pressure sensor, image sensor and infrared sensor are all installed at the front end of the probe 4, and the pressure sensor, image sensor and infrared sensor are all connected to the controller signal.

[0057] It also includes an early warning component, which includes a buzzer and an indicator light, both of which are connected to the controller signal; when the pressure monitored by the pressure sensor exceeds the safety pressure threshold preset in the controller, the controller controls the buzzer to sound an alarm, and the indicator light flashes at the same time to alert medical staff; when the image sensor detects an abnormal lesion area inside the patient's ear, nose and throat cavity, the controller controls the indicator light to flash at a specific frequency to alert medical staff; when the temperature detected by the infrared sensor exceeds or is lower than the normal body temperature range, the controller controls the buzzer to emit alarm sounds of different frequencies, and the indicator light displays different colors to alert medical staff and patients.

[0058] The specific implementation process is as follows: medical staff need to pre-set the safety pressure threshold (set according to the tolerance of the human body cavity) and the normal body temperature range reference value (such as 36℃-37.2℃) in the controller.

[0059] When medication is needed, the medical professional holds the medication delivery device and slowly inserts the probe 4 into the patient's ENT cavity. The pressure sensor, image sensor, and infrared sensor simultaneously begin operating. The pressure sensor monitors the pressure of the probe 4 in contact with the patient's cavity in real time and transmits this data to the controller. The image sensor continuously captures images of the interior of the patient's cavity, using an image recognition algorithm to initially analyze whether there are any abnormal lesions. The infrared sensor detects the temperature inside the cavity and feeds this data back to the controller.

[0060] If, during the insertion of the probe 4, the pressure detected by the pressure sensor exceeds the safety pressure threshold preset in the controller, the controller immediately controls the buzzer to emit a sharp alarm sound, and the indicator light flashes rapidly, reminding the medical staff to stop the insertion action to avoid damage to the patient's cavity, and appropriately adjust the angle and insertion force of the probe 4; if the image sensor detects a suspected abnormal lesion area inside the patient's ear, nose and throat cavity, the controller controls the indicator light to flash slowly at a specific frequency, prompting the medical staff to focus on the area, and suspend the operation if necessary for further inspection and confirmation; when the temperature detected by the infrared sensor exceeds or is lower than the normal body temperature range, the controller controls the buzzer to emit alarm sounds of different frequencies according to the degree of temperature deviation, and the indicator light displays different colors (such as red for too high temperature and blue for too low temperature), reminding the medical staff that the patient's cavity may have fever, inflammation or other abnormal conditions.

[0061] Example 4:

[0062] The difference from Example 3 is that a hardness adjustment component (not shown in the figure) is provided on the drug delivery hose 3, and the hardness adjustment component includes several air bags and an air pump distributed along the length direction of the drug delivery hose 3. The air pump is installed on the outside of the drug storage cavity 2, and the output end of the air pump is connected to the air bag. The end of the air bag away from the air pump is connected to the air bag, and the controller is connected to the air pump signal. The controller controls the air pump to inflate or deflate the air bag according to the patient's ear, nose and throat cavity information obtained by the monitoring component, thereby adjusting the hardness of the drug delivery hose 3.

[0063] The specific implementation process is as follows: When administering medication to a patient, the medical staff holds the medication delivery device and slowly inserts the probe 4 into the patient's ENT cavity. The pressure sensor, image sensor, and infrared sensor simultaneously begin operating. The pressure sensor monitors the pressure of the probe 4 in real time when it contacts the patient's cavity and transmits the data to the controller. The image sensor continuously acquires images of the patient's cavity and uses an image recognition algorithm to preliminarily analyze whether there are abnormal lesions. The infrared sensor detects the temperature inside the cavity and feeds the data back to the controller. Simultaneously, the controller controls the hardness adjustment component based on the cavity information acquired by the monitoring component. If the image sensor indicates that the cavity is narrow or curved, the controller controls the air pump to slightly deflate the airbag, reducing the hardness of the medication hose 3 and making it more flexible, allowing for smoother insertion and minimizing damage to the cavity wall. If the pressure sensor indicates a low pressure and the cavity is relatively spacious, the controller controls the air pump to inflate the airbag, increasing the hardness of the medication hose 3 and ensuring stable drug delivery during medication.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
