Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical equipment, and particularly relates to a smelling device for epilepsy treatment, in particular to a medicament smelling device capable of realizing synchronous oxygen supply in combination with a nasal oxygen tube. BACKGROUND

[0002] Epilepsy is a nervous system disease caused by abnormal discharge of neurons in the brain. Patients often lose consciousness and have limb convulsions during seizures. Currently, drug inhalation is often used in clinical practice to intervene in acute seizures, and the drug is quickly absorbed through the nasal mucosa to achieve the effect of sedation and antispasticity. There are various smelling treatment devices in the prior art, and the typical structure includes a medicament storage cavity, a gas suction unit and an atomizing nozzle. When in use, the device is inserted into the patient's nasal cavity, and the airflow is formed by suctioning external air to push the liquid or atomized medicament to the deep part of the nasal cavity.

[0003] However, the existing smelling device has significant defects in clinical application: because the device continuously sucks external air during operation, the original oxygen supply in the patient's nasal cavity is partially blocked by the medicament airflow. The respiratory system of the patient is often unstable during a seizure, and at this time, the nasal passage is occupied by the smelling device, the oxygen intake efficiency is reduced, and hypoxia is easy to occur, which may increase the risk of brain damage. In addition, some devices use a closed design to improve the efficiency of medicament delivery, but they completely block the exchange of nasal cavity and external gas, further exacerbating the problem of insufficient oxygen supply.

[0004] The present application provides a smelling device for epilepsy treatment, which can realize synchronous oxygen supply in combination with a nasal oxygen tube.

[0005] It is specifically emphasized that the methods described in this section are not necessarily methods that have been previously conceived or used.

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Reference Figures 1-4 As shown, a sniffing device for treating epilepsy in this embodiment includes a drug sniffing mechanism and an air source docking mechanism.

[0032] The medicine inhalation mechanism is not shown in the prior art improved device, which contains a medicine storage cavity, an atomization unit and a negative pressure generator inside. The negative pressure generator sucks the medicine out of the storage cavity and atomizes it through the suction airflow, and finally sprays it into the patient's nasal cavity through the nozzle. The difference between the medicine inhalation mechanism and the prior art is that the air inlet end of the medicine inhalation mechanism is in communication with the air source docking mechanism.

[0033] In this embodiment, the air source docking mechanism can be connected with the nasal oxygen tube, and after connection, the nasal cannula 322 of the oxygen supply nasal plug of the nasal oxygen tube is covered to form a closed air path. When the medicine inhalation mechanism sucks air, the oxygen discharged from the nasal cannula 322 will be sucked into the medicine inhalation mechanism to participate in the driving of the medicine.

[0034] In use, the air source docking mechanism is connected with the nasal oxygen tube, and then the medicine inhalation mechanism is started. The internal negative pressure of the medicine inhalation mechanism sucks the gas in the air source docking mechanism, that is, the oxygen discharged from the nasal cannula 322 is sucked, so that the oxygen can replace the external air as the power source. This design ensures that the patient's nasal cavity always obtains oxygen supply during treatment, avoiding the risk of hypoxia caused by traditional inhalation devices.

[0035] In this embodiment, the air source docking mechanism includes an upper shell 21, a sliding connecting piece 22, a lower shell 23 and a first elastic piece 24. The upper end of the upper shell 21 is in communication with the air inlet end of the medicine inhalation mechanism, and in this embodiment, it is communicated through a hose. The lower end of the upper shell 21 is an open split end, the sliding connecting piece 22 is fixed to the upper shell 21 and is in longitudinal sliding connection with the lower shell 23, so that the upper shell 21 and the lower shell 23 can be relatively opened and closed. The upper end of the lower shell 23 is an open split end matched with the upper shell 21, and when the upper shell 21 and the lower shell 23 are relatively slid and closed, they can be split to form a containing space for containing the oxygen supply nasal plug. The first elastic piece 24 is arranged between the lower shell 23 and the sliding connecting piece 22, for pushing the lower shell 23 to move to one side of the upper shell 21, so that the upper shell 21 and the lower shell 23 can maintain an elastic closing tendency in a natural state.

[0036] When the nasal oxygen tube needs to be connected, the operator pulls down the lower shell 23 to overcome the elastic force of the first elastic piece 24 to separate the upper and lower shells. The oxygen supply nasal plug of the nasal oxygen tube is placed between the upper and lower shells, and after releasing the pulling piece 25, the first elastic piece 24 pushes the lower shell 23 to move upward, so that the nasal cannula 322 is completely wrapped in the containing space.

[0037] In the embodiment, the upper shell 21 is provided with receiving grooves on the left and right sides of the lower end for accommodating the horizontal pipe 321 of the oxygen supply nasal plug, and the four receiving grooves are aligned to form a receiving ring groove when the upper shell 21 and the lower shell 23 are combined with each other, so as to accommodate the left and right ends of the horizontal pipe 321. After the air source docking mechanism is connected to the nasal oxygen tube, the left and right ends of the horizontal pipe 321 are embedded in the corresponding receiving ring grooves, so that the air-tight connection can be ensured.

[0038] In the embodiment, the air source docking mechanism further comprises a pulling member 25 connected to the lower shell 23, which facilitates the user to apply force to the lower shell 23 to open the upper and lower shells.

[0039] In the embodiment, the pulling member 25 is longitudinally sealed through the lower shell 23, and the pulling member 25 is a hollow structure with an open upper end. The lower part of the pulling member 25 is in communication with the external atmosphere through a gas filter 251, and external air can enter the pulling member 25 through the gas filter 251. The gas filter 251 can be a medical-grade hydrophobic filter film, which can effectively block dust and microorganisms when air is inhaled.

[0040] In the embodiment, the air source docking mechanism further comprises a second elastic member 26 arranged between the lower shell 23 and the pulling member 25 to push the pulling member 25 to move to one side of the upper shell 21.

[0041] The inner side of the upper shell 21 has an upper part for sealingly docking with the upper end of the pulling member 25, and the upper shell 21 is in communication with the air inlet end of the medicament inhalation mechanism through the docking cylinder 211.

[0042] In the natural state, the second elastic member 26 can keep the pulling member 25 and the docking cylinder 211 in an elastic closing tendency. When the operator pulls down the pulling member 25, the pulling member 25 will move downward relative to the lower shell 23 by overcoming the elastic force of the second elastic member 26, and in addition, the second elastic member 26 will drive the lower shell 23 to overcome the elastic force of the first elastic member 24 to separate the upper and lower shells.

[0043] When the medicament inhalation mechanism is not connected to the nasal oxygen tube, the upper end of the pulling member 25 will abut against the lower end of the docking cylinder 211 under the action of the elastic force of the second elastic member 26. In this state, the gas sucked by the medicament inhalation mechanism is the gas filtered by the gas filter 251 in the external atmosphere and then entering the pulling member 25, so that clean air can be used as the medicament driving gas source.

[0044] When the medicament inhalation mechanism is connected with the nasal oxygen tube, the upper shell 21 and the lower shell 23 will be mutually butted under the elastic force of the first elastic member 24 to cover the nasal cannula 322 of the oxygen supply nasal plug, and the upper end of the pulling member 25 will be in sealing abutment with the side of the oxygen supply nasal plug under the elastic force of the second elastic member 26, so as to close the upper end of the pulling member 25. In this state, the gas sucked by the medicament inhalation mechanism is the oxygen discharged from the nasal cannula 322, so that the oxygen can be used as the propellant gas source of the medicament.

[0045] The external air driving mode is suitable for scenarios where the patient does not need auxiliary oxygen supply, such as mild onset, normal spontaneous breathing, or initial stage of first aid. In this mode, the device drives the medicament by filtering external air, and the operation can be started directly. It has the advantages of fast response and easy access to gas source, and is especially suitable for outpatient, home or temporary scenarios where oxygen supply equipment is missing.

[0046] The oxygen driving mode is designed for patients with severe symptoms who need to inhale oxygen simultaneously. When the device is connected to the nasal oxygen tube, it automatically switches to sucking medical oxygen to drive the medicament. This mode maintains continuous oxygen delivery through a closed air path, and is suitable for high-risk situations such as status epilepticus, respiratory depression, or low blood oxygen. It can achieve seamless cooperation between treatment and oxygen therapy in scenarios such as ICU and ambulance, avoiding the risk of hypoxia caused by blocking the nasal cavity with traditional devices.

[0047] The two modes are automatically switched by mechanical linkage: when the nasal oxygen tube is not connected, the elastic sealing structure preferentially guides the filtered air; when the nasal oxygen tube is connected, the device triggers the air path switching using oxygen pressure, ensuring that the treatment process does not need to be interrupted. This design not only retains the flexibility of independent use, but also meets the rigid demand for simultaneous oxygen supply for critical patients, significantly improving treatment safety and scenario adaptability through intelligent gas source adaptation.

[0048] In this embodiment, the upper end of the pulling member 25 has a sealing ring 252 around its periphery, which plays a key role in achieving bidirectional dynamic sealing.

[0049] When the device is connected to the nasal oxygen tube, the sealing ring 252 tightly fits the outer wall of the transverse tube 321 of the oxygen supply nasal plug, forming a seal to prevent oxygen from leaking between the pulling member 25 and the transverse tube 321. This seal ensures that the oxygen is completely directed to the medicament inhalation mechanism.

[0050] When the nasal oxygen tube is not connected, the sealing ring 252 abuts against the lower end of the docking barrel 211, forming a seal to prevent unfiltered external air from directly entering the medicament inhalation mechanism. At this time, only the air purified by the gas filter 251 is allowed to pass, avoiding the entry of pollutants into the patient's respiratory tract without passing through the filtering link.

[0051] The sealing ring 252 can be made of medical silicone or fluororubber, which has elastic properties to buffer the mechanical impact when the pulling member 25 contacts with the horizontal tube 321 / the docking cylinder 211, reducing the wear of the components.

[0052] The lower end of the pulling member 25 is provided with a lower pull ring 253, and the upper end of the upper shell 21 is provided with upper pull rings 212 on the left and right sides. Medical staff can insert their thumbs into the lower pull ring 253, and their index fingers and middle fingers into the two upper pull rings 212, and then simultaneously force to the opposite sides. In this way, the nasal oxygen tube can be connected and separated by one hand through the cooperation of the lower pull ring 253 and the upper pull ring 212, so as to quickly operate and save first aid time (such as quickly completing oxygen supply and drug administration within the golden 5 minutes of a seizure).

[0053] The upper end of the pulling member 25 is provided with first abutting portions 254 extending horizontally on the left and right sides, and the second elastic members 26 are two, which are distributed on the left and right sides of the pulling member 25. The upper end of the second elastic member 26 abuts against the corresponding first abutting portion 254, and the lower end abuts against the inner bottom of the lower shell 23. This technical solution realizes precise force control through the symmetrical distribution of the elastic support structure. The first abutting portions 254 on the left and right sides of the pulling member 25 serve as the force application fulcrum of the second elastic members 26, and the symmetrical layout of the two second elastic members 26 can balance the transmission of elastic force, ensuring that the pulling member 25 remains vertically stable during up and down movement, and avoiding sealing failure or component jam caused by unilateral deviation.

[0054] The upper end of the pulling member 25 is shaped as a concave circular arc matching the horizontal tube 321 of the oxygen nasal plug, and the lower end of the docking cylinder 211 is shaped as a convex circular arc matching the shape of the upper end of the pulling member 25. This technical solution realizes sealing optimization through curved surface matching design. The concave circular arc at the upper end of the pulling member 25 precisely fits the outer contour of the horizontal tube 321 of the oxygen nasal plug, forming a stable contact seal when connecting the nasal oxygen tube. The convex circular arc at the lower end of the docking cylinder 211 forms a double-curved surface sealing pair with the concave surface of the pulling member 25, which tightly fits in the air driving mode to prevent unfiltered air from seeping in.

[0055] The second abutting portions 231 are horizontally arranged inside the lower shell 23, the sliding connecting piece 22 has two third abutting portions 221 at the lower end, which are arranged in the lower shell 23 and correspond to the two second abutting portions 231, and the first elastic members 24 are arranged at the upper end of the second abutting portions 231 and the lower end of the third abutting portions 221. The technical scheme realizes stable closure and accurate reset of the shell through the symmetrical elastic guiding structure. The second abutting portions 231 inside the lower shell 23 and the third abutting portions 221 of the sliding connecting piece 22 form a sliding guide rail, and the two first elastic members 24 are arranged on the left and right sides, the upper end of the first elastic member 24 abuts against the second abutting portion, and the lower end of the first elastic member 24 abuts against the third abutting portion, thereby forming a bidirectional elastic support system. The design makes the lower shell 23 always move along a fixed track during the up-down sliding process, avoids misalignment or air tightness failure caused by deflection, the symmetrical elastic members balance the closing pressure, ensures that the clamping force of the upper and lower shells 21 / 23 on the nasal oxygen tube is uniform when the upper and lower shells 21 / 23 are combined, and prevents deformation of the tube or oxygen leakage caused by unilateral overload.

[0056] In summary, the application realizes safe cooperation of sniffing therapy and oxygen therapy through innovative gas path integration design without changing the existing nasal oxygen tube structure. Compared with the traditional device, the blood oxygen concentration can be effectively improved under the same amount of medicament, and the application is especially suitable for patients with status epilepticus accompanied by respiratory depression.

[0057] The above examples only exemplarily illustrate the principles and effects of the application, and are not used to limit the application. Any person skilled in the art can modify or change the above examples without departing from the spirit and scope of the application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical thought of the application should be covered by the claims of the application.
