Description

Technical Field

[0001] This invention relates to the field of medical and nursing technology, specifically to a device for suppressing sneezing after pituitary tumor surgery. Background Technology

[0002] Pituitary tumors are a group of tumors originating from the anterior or posterior pituitary lobes or residual epithelial cells of the craniopharynx. Most are benign (less than 1% are malignant), but because the pituitary gland is an important "endocrine center" in the human body, tumors may cause endocrine disorders and neurological dysfunction by compressing surrounding tissues or abnormally secreting hormones.

[0003] The choice of surgical site for pituitary tumors is primarily based on the anatomical location of the pituitary gland (located in the sella turcica at the base of the brain, adjacent to the nasal cavity and sphenoid sinus below, and close to the optic nerve and hypothalamus above). The principle is "minimally invasive and precise tumor resection." Surgical approaches are mainly divided into two categories: the transsphenoidal approach (minimally invasive surgery, accounting for over 90%) and the craniotomy approach (traditional surgery, used only for complex cases). The mainstream surgical approach is the transsphenoidal approach, which is currently the preferred method for pituitary tumor surgery (especially suitable for microadenomas, macroadenomas, and even some giant adenomas that do not invade important blood vessels). Its core logic is to "utilize the natural anatomical passages of the nasal cavity, sphenoid sinus, and pituitary gland". It does not require craniotomy, is less invasive, and has a faster recovery. The surgical site and path are entirely inside the nasal cavity and skull base, with no external incisions.

[0004] After pituitary tumor surgery, if a patient sneezes due to external stimuli, the body experiences a brief surge in thoracic and abdominal pressure. This pressure is transmitted to the intracranial cavity via blood vessels and cerebrospinal fluid, causing a transient increase in intracranial pressure. Simultaneously, the head muscles contract violently, potentially pulling on tissues at the surgical site, such as the repaired sella turcica floor, dura mater, and nasal mucosa. This increased intracranial pressure and tissue traction can negatively impact postoperative recovery, especially in the early postoperative period (usually within 1-2 weeks after surgery, when the surgical site has not yet fully healed). Therefore, suppressing sneezing after pituitary tumor surgery is crucial. To address these issues, a device for suppressing sneezing after pituitary tumor surgery is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a device for suppressing sneezing after pituitary tumor surgery, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery according to the present invention, the device includes a face mask, a nasal wing compression module, and an external air treatment module. The mask is worn on the patient's head by a strap. The sides of the mask are equipped with detachable nasal compression modules for pressing the patient's nasal wings. The front of the mask is equipped with an external air processing module for processing the outside air. The sides of the external air processing module are equipped with second one-way valves for exhalation that are fixedly connected to the mask. A control module is also installed on the outside of the mask. The nose wing compression module includes a mounting frame that is spirally connected to the mask. A sealing cover is installed on the other side of the mounting frame. A reciprocating pushing mechanism is also installed inside the mounting frame. A rotating column is rotatably connected to the reciprocating end of the reciprocating pushing mechanism. An inclined rod is fixedly connected to the outside of the rotating column. An extrusion plate is fixedly connected to the other side of the inclined rod. The external air handling module includes an air intake hood that is spirally connected to the face mask. Symmetrically arranged blocking blocks are installed inside the air intake hood. A filter mechanism, air handling components, and airflow detection mechanism are also installed inside the air intake hood. An air retention mechanism is installed at the bottom of the air intake hood. The air handling unit includes a second support ring, and an air heating mechanism for heating the air and a humidification mechanism for humidifying the air are installed inside the second support ring. The airflow detection mechanism includes a third support ring. Inside the third support ring is a reducer for airflow. Outside the reducer is a pressure sensor for monitoring the gas pressure inside the third support ring. Inside the reducer is a first one-way valve. On the other side of the third support ring are symmetrically arranged mounting plates that extend into the air handling unit. The bottom mounting plate is spirally connected to an air retention mechanism.

[0007] As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery as described in this invention, the filtering mechanism includes a first support ring, a filter screen is installed inside the first support ring, and a filter cloth is detachably installed on the side of the filter screen facing the air intake hood.

[0008] After pituitary tumor surgery, if a patient sneezes due to external stimuli, the body experiences a brief surge in thoracic and abdominal pressure. This pressure is transmitted to the intracranial cavity via blood vessels and cerebrospinal fluid, causing a transient increase in intracranial pressure. Simultaneously, the head muscles may contract violently, potentially pulling on tissues at the surgical site, such as the repaired sella turcica floor, dura mater, and nasal mucosa. This increased intracranial pressure and tissue traction can negatively impact postoperative recovery, especially in the early postoperative period. Therefore, suppressing sneezing after pituitary tumor surgery is crucial. Yes, by having the patient wear a mask, if the patient's nasal cavity is stimulated, the patient will not sneeze immediately. Instead, the patient will experience sneezing precursors. The process involves stimulation perception, information processing, coordinated muscle contraction, and airflow ejection. The airflow detection mechanism of the external air handling module monitors whether sneezing precursors are present. Once sneezing precursors are detected, the control module activates the nasal wing compression module. The nasal wing compression module presses on both sides of the nasal wings, which can relieve the sensitivity of the nasal mucosa and thus suppress the urge to sneeze, playing a positive role in the patient's postoperative recovery.

[0009] As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery as described in this invention, the air heating mechanism includes a heating plate fixedly connected to the inner side of the second support ring, a uniformly distributed heating pipe fixedly connected to one side of the heating plate, an air inlet pipe connected to one side of each heating pipe, an exhaust pipe connected to the other side of the heating pipe, and the exhaust pipe passes through both ends of the heating plate. The heating element has mounting slots on both the top and bottom sides, and mounting plates are installed in the mounting slots.

[0010] As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery as described in this invention, the heating pipe is curved and the cross-section of the heating pipe is semi-circular.

[0011] As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery as described in this invention, the humidification mechanism includes a support plate fixedly connected to a second support ring, a water storage tray fixedly connected to the center of the support plate, a water injection plug installed in the center of the water storage tray, and evenly distributed guide tubes connected to the outside of the water storage tray. Each guide tube is equipped with an absorbent rope, one end of which extends into the water storage tray, and the other end of which is connected to a humidifying and breathable fabric sheet. The outer side of the humidifying and breathable fabric sheet is fixedly connected to the support plate.

[0012] An external air processing module is installed on the front of the mask to process outside air. Inside the external air processing module is a filter mechanism that filters the air entering the mask, reducing the stimulation of the sensitive nerve endings in the nasal cavity by the external environment. At the same time, the air heating and humidification mechanisms can humidify and heat the air to ensure a comfortable environment and reduce the chance of the patient sneezing.

[0013] As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery as described in this invention, the air retention mechanism includes a threaded cylinder that is spirally connected to the mounting plate. The threaded cylinder passes through the bottom of the air inlet hood, and an axe-shaped air storage bladder is fixedly connected to the bottom of the threaded cylinder. A deformation strip for supporting the air storage bladder is installed inside the air storage bladder.

[0014] When a patient inhales heavily, a large amount of air needs to pass through the filtration mechanism and air handling unit in a short period of time. At this time, air intake may be obstructed. The air reserve mechanism is designed to compensate for the air intake in time and avoid air intake obstruction. To ensure stable and accurate monitoring of short-term internal airflow, a variable-diameter tube is installed to reduce the diameter of the airflow channel, artificially creating airflow velocity and thus increasing air pressure. In the event of a short-term large intake of air, the air pressure sensor can stably monitor and determine whether a sneezing state has occurred. This plays a positive role in subsequent dust suppression and sneezing, avoiding surgical-related complications caused by the impact of a sneeze.

[0015] As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery as described in this invention, the first one-way valve includes a first mounting plate fixedly connected to a reducing tube. One side of the first mounting plate is recessed, and the interior of the first mounting plate has uniformly distributed first vent holes. A first rubber disk in the shape of an umbrella is fixedly connected to the center of the first mounting plate, and one side of the first rubber disk is attached to the inner side of the first mounting plate.

[0016] As an alternative embodiment of the device for suppressing sneezing after pituitary tumor surgery as described in this invention, the second one-way valve includes a second mounting plate fixedly connected to the mask. One side of the second mounting plate is recessed, and the interior of the second mounting plate has evenly distributed second ventilation holes. A second rubber soft disk arranged in an umbrella shape is fixedly connected to the center of the second mounting plate, and the second rubber soft disk is located on the outside of the mask.

[0017] The simultaneous installation of the first and second one-way valves ensures unidirectional airflow inside the mask, preventing stuffiness and ensuring smooth air circulation.

[0018] Compared with the prior art, the beneficial effects of the present invention are: By having the patient wear a mask, if the patient's nasal cavity is stimulated, the patient will not sneeze immediately. Instead, the patient will have a sneezing precursor. The process involves stimulation perception, information processing, coordinated muscle contraction, and airflow ejection. The airflow detection mechanism of the external air handling module monitors whether there is a sneezing precursor. Once a sneezing precursor is detected, the control module activates the nasal wing compression module. The nasal wing compression module presses on both sides of the nasal wings, which can relieve the sensitivity of the nasal mucosa and thus suppress the urge to sneeze, playing a positive role in the patient's postoperative recovery. Furthermore, during heavy intake, a large amount of air is required to pass through the filtration mechanism and the air handling unit. At this time, air intake may be obstructed. The air reserve mechanism is designed to compensate for the intake volume in time and avoid air intake obstruction. To ensure stable and accurate monitoring of short-term internal airflow, a variable-diameter tube is installed to reduce the diameter of the airflow channel, artificially creating airflow velocity and thus increasing air pressure. In the event of a short-term large intake of air, the air pressure sensor can stably monitor and determine whether a sneezing state has occurred. This plays a positive role in subsequent dust suppression and sneezing, and avoids surgical complications caused by the impact of a sneeze. An external air processing module is installed on the front of the mask to process the outside air. Inside the external air processing module is a filter mechanism that can filter the air entering the mask and reduce the stimulation of the sensitive nerve endings in the nasal cavity by the external environment. At the same time, the air heating and humidification mechanisms can humidify and heat the air to ensure a comfortable environment and reduce the chance of the patient sneezing. The simultaneous installation of the first and second one-way valves ensures unidirectional airflow inside the mask, preventing stuffiness and ensuring smooth air circulation.

[0021] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The present invention provides a technical solution: A device for suppressing sneezing after pituitary tumor surgery includes a face mask 1, a nasal wing compression module 2, and an external air handling module 3; The mask 1 is worn on the patient's head by a strap. The sides of the mask 1 are equipped with detachable nasal compression modules 2 for pressing the patient's nasal wings. The front of the mask 1 is equipped with an external air processing module 3 for processing external air. The sides of the external air processing module 3 are provided with second one-way valves 7 that are fixedly connected to the mask 1 for exhalation. The outside of the mask 1 is also equipped with a control module 8. The nose wing compression module 2 includes a mounting frame 201 that is spirally connected to the mask 1. A sealing cover 202 is installed on the other side of the mounting frame 201. A reciprocating pushing mechanism 203 is also installed inside the mounting frame 201. A rotating column 204 is rotatably connected to the reciprocating end of the reciprocating pushing mechanism 203. An inclined rod 205 is fixedly connected to the outside of the rotating column 204. An extrusion plate 206 is fixedly connected to the other side of the inclined rod 205. The external air handling module 3 includes an air intake hood 301 that is spirally connected to the mask 1. The air intake hood 301 has symmetrically arranged blocking blocks 302 installed inside. The air intake hood 301 also has a filter mechanism, an air handling component 306 and an airflow detection mechanism installed inside. An air retention mechanism is installed at the bottom of the air intake hood 301. The air handling unit 306 includes a second support ring 4, and an air heating mechanism 5 for heating the air and a humidification mechanism 6 for humidifying the air are installed inside the second support ring 4. The airflow detection mechanism includes a third support ring 307. A reducer 308 for airflow is installed inside the third support ring 307. A pressure sensor 314 for monitoring the gas pressure inside the third support ring 307 is installed outside the reducer 308. A first one-way valve 309 is also installed inside the reducer 308. A mounting plate 310 arranged symmetrically is installed on the other side of the third support ring 307. The mounting plate 310 extends into the air handling unit 306, and an air retention mechanism is spirally connected inside the bottom mounting plate 310.

[0022] The filtration mechanism includes a first support ring 304, a filter screen 305 is installed inside the first support ring 304, and a filter cloth 303 is detachably installed on the side of the filter screen 305 facing the air intake shroud 301.

[0023] After pituitary tumor surgery, if a patient sneezes due to external stimuli, a temporary increase in thoracic and abdominal pressure occurs. This pressure is transmitted to the intracranial cavity via blood vessels and cerebrospinal fluid, causing a transient increase in intracranial pressure. Simultaneously, the head muscles may contract violently, potentially pulling on tissues at the surgical site, such as the repaired sella turcica floor, dura mater, and nasal mucosa. This increased intracranial pressure and tissue traction can negatively impact postoperative recovery, especially in the early postoperative period (usually 1-2 weeks) when the surgical site has not fully healed. Therefore, during pituitary tumor surgery... Post-sneez suppression is crucial. By having the patient wear a mask 1, if the patient's nasal cavity is stimulated, the patient will not sneeze immediately. Instead, the patient will experience sneezing precursors. The process involves stimulation perception, information processing, coordinated muscle contraction, and airflow ejection. The airflow detection mechanism of the external air processing module 3 monitors whether there are sneezing precursors. Once sneezing precursors are detected, the control module 8 activates the nasal wing compression module 2. The nasal wing compression module 2 presses on both sides of the nasal wings, which can relieve the sensitivity of the nasal mucosa and thus suppress the urge to sneeze. This has a positive effect on the patient's postoperative recovery. Also includes the following: The process of sneezing can be broken down into the following four steps: Stimulus perception: The nasal mucosa is covered with a large number of sensitive nerve endings (such as the trigeminal nerve). When these endings come into contact with foreign objects or stimuli, they will immediately send signals to the brain's "reflex center" (medulla oblongata). Signal processing: After receiving an "abnormal signal," the brain quickly integrates the information and determines that a "cleanup process" needs to be initiated. Muscle coordination: The brain sends instructions to related muscles throughout the body. First, the muscles of the nasal cavity and throat contract (closing the airway momentarily), followed by strong contraction of the core muscles such as the chest cavity, abdomen, and diaphragm, which rapidly compress the air in the lungs. Airflow eruption: Finally, the muscles in the throat suddenly relax, and compressed air is expelled from the nasal cavity and mouth at a speed of 150-200 km / h, while carrying out irritants in the nasal cavity, thus completing a sneeze; This device blocks the process of muscle synergistic contraction. The air pressure sensor 314 set on the outside of the airflow detection mechanism detects that the air flow exceeds the set threshold in a short time. At this time, it is determined that a sneeze is about to occur and sends a signal to the control module 8. The control module 8 controls the reciprocating push mechanism 203 to drive the rotating column 204 to move back and forth. The rotating column 204 drives the tilting rod 205 and the squeezing plate 206 to move back and forth. The squeezing plates 206 on both sides squeeze the patient's nasal wings back and forth to relieve the sensitivity of the nasal mucosa and thus suppress the urge to sneeze. A blocking block 302 is set inside the air intake hood 301 to ensure the installation position of the filter mechanism and serve as a positioning purpose. An air handling unit 306 is also installed on one side of the filter mechanism. Meanwhile, the top of the air pre-reservation mechanism is installed between the air heating mechanism 5 and the humidification mechanism 6 of the air handling unit 306. When sneezing and taking a large amount of air, the air pre-reservation mechanism performs air compensation, which can reduce the resistance of external air entering and ensure smooth air flow. At the same time, the air inside the air pre-reservation mechanism can be treated by the air heating mechanism 5 to a certain extent to ensure the air temperature and humidity and create a comfortable environment. To ensure the accurate monitoring of the air pressure sensor 314 and thus determine whether a sneeze has occurred, the variable diameter tube 308 is designed to artificially create an air pressure difference, which facilitates monitoring by the air pressure sensor 314. The mounting plate 310 at the bottom has threaded holes inside, which facilitates connection with the air pre-reservation mechanism. External air enters the air intake hood 301 and passes through the filter cloth 303 and the filter screen 305 to achieve the purpose of filtering external air.

[0024] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 5 and Figure 6 Specifically, the air heating mechanism 5 includes a heating element 501 fixedly connected to the inner side of the second support ring 4. A uniformly distributed heating pipe 502 is fixedly connected to one side of the heating element 501. An air inlet pipe 503 is connected to one side of each heating pipe 502. An exhaust pipe 504 is connected to the other side of the heating pipe 502, and the exhaust pipe 504 passes through both ends of the heating element 501. The heating element 501 has mounting slots on its upper and lower sides, and mounting plates 310 are installed in the mounting slots.

[0025] The heating pipe 502 is curved and has a semi-circular cross-section.

[0026] The humidification mechanism 6 includes a support plate 601 fixedly connected to the second support ring 4. A water storage plate 605 for storing water is fixedly connected to the center of the support plate 601. A water injection plug 606 is installed in the center of the water storage plate 605. The outer side of the water storage plate 605 is connected to a uniformly distributed guide tube 604. A water-absorbing rope 603 is installed inside each of the guide tubes 604. One end of the water-absorbing rope 603 extends into the water storage plate 605, and the other end of the water-absorbing rope 603 is connected to a humidifying and breathable cloth sheet 602. The outer side of the humidifying and breathable cloth sheet 602 is fixedly connected to the support plate 601.

[0027] An external air processing module 3 for processing external air is installed on the front side of the mask 1. A filter mechanism is set inside the external air processing module 3 to filter the air entering the mask 1, reducing the stimulation of the sensitive nerve endings in the nasal cavity by the external environment. At the same time, the air heating mechanism 5 and the humidification mechanism 6 can humidify and heat the air to ensure a comfortable environment and reduce the chance of the patient sneezing. Also includes the following: When the air is dry, it is filtered by the filtration mechanism and then humidified by the humidifying breathable cloth 602 of the humidifying mechanism 6. Water is placed inside the water storage tray 605. The water inside the water storage tray 605 can slowly wet the humidifying breathable cloth 602 through the water absorption rope 603 to ensure continuous humidification of the air. The guide tube 604 can prevent water from seeping outward through the water absorption rope 603, which would not only waste water but also result in poor air humidification. The water filling plug 606 makes it easy to add water. When the air is humid, the humidifying mechanism 6 can be removed or water can be left out of the water storage tray 605 to avoid excessive humidity. The humidified air can enter the heating pipe 502 through the air inlet pipe 503. The heating pipe 502 has a semi-circular cross-section, which facilitates direct contact between the air and the heating element 501, thereby achieving the purpose of heating the air. The heated air can be discharged through the exhaust pipe 504 to ensure the air temperature and avoid the stimulation of the patient's nasal cavity by excessively cold air. The mounting slots on the upper and lower sides of the heating element 501 can facilitate the insertion of the mounting plate 310, which facilitates the installation of the air pre-reservation mechanism.

[0028] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 8 Specifically, the air retention mechanism includes a threaded cylinder 313 that is spirally connected to the mounting plate 310. The threaded cylinder 313 passes through the bottom of the air intake hood 301. An air storage bladder 311 with an axe-shaped arrangement is fixedly connected to the bottom of the threaded cylinder 313. A deformation strip 312 for supporting the air storage bladder 311 is installed inside the air storage bladder 311.

[0029] When a patient inhales a large amount of air, a large amount of air needs to pass through the filtration mechanism and the air handling unit 306 in a short period of time. At this time, air intake may be obstructed. The air reserve mechanism is set up to compensate for the air intake in time and avoid air intake obstruction. To ensure stable and accurate monitoring of the internal airflow over short periods, the variable diameter tube 308 is designed to reduce the diameter of the airflow channel, artificially creating airflow velocity and thus increasing air pressure. In the event of a short period of heavy inhalation, the air pressure sensor 314 can stably monitor and determine whether a sneezing state has occurred. This plays a positive role in subsequent dust suppression and sneezing, and avoids surgical complications caused by the impact of a sneeze. Also includes the following: During the process of taking a large amount of air, i.e., the "power-gathering" process of sneezing, the gas inside the air reservoir 311 can be extracted, and the air reservoir 311 deflates to compensate for the external air. After the air compensation process is completed, the air reservoir 311 can be restored by the action of the deformation strip 312 and the air reservoir 311 itself. The air reservoir 311 is made of rubber and has a certain recovery function. The deformation strip 312 is also made of rubber, which helps the air reservoir 311 to return to its original shape and facilitates the next cycle of use.

[0030] Example 4: This example is an improvement on Example 3. Please refer to [link / reference]. Figure 7 and Figure 9 Specifically, the first one-way valve 309 includes a first mounting plate 3091 fixedly connected to the reducing pipe 308. One side of the first mounting plate 3091 is recessed, and the interior of the first mounting plate 3091 is provided with uniformly distributed first vent holes 3092. A first rubber disk 3093 in the shape of an umbrella is fixedly connected to the center of the first mounting plate 3091, and one side of the first rubber disk 3093 is attached to the inner side of the first mounting plate 3091.

[0031] The second one-way valve 7 includes a second mounting plate 701 fixedly connected to the face mask 1. One side of the second mounting plate 701 is recessed. The interior of the second mounting plate 701 has evenly distributed second vent holes 702. A second rubber soft disk 703 arranged in an umbrella shape is fixedly connected to the center of the second mounting plate 701, and the second rubber soft disk 703 is located on the outside of the face mask 1.

[0032] The first one-way valve 309 and the second one-way valve 7 are set at the same time to ensure that the gas inside the mask 1 flows in one direction, avoids stuffiness inside the mask 1, and ensures smooth air circulation. Also includes the following: Both the first mounting plate 3091 and the second mounting plate 701 have evenly distributed first vent holes 3092 and second vent holes 702 inside. During inhalation, the first rubber disk 3093 moves from the outer periphery towards the inner side of the mask 1 to facilitate air entry. During exhalation, the second rubber disk 703 moves outward to facilitate air expulsion, thereby achieving unidirectional airflow. Both the first rubber disk 3093 and the second rubber disk 703 are made of rubber, which allows for easy deformation and movement of the disk periphery, thus aiding in air expulsion.
