Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and specifically relates to a sniffing device for treating epilepsy, and more particularly to a medicine sniffing device that can be combined with a nasal oxygen tube to achieve synchronous oxygen supply. Background Art

[0002] Epilepsy is a neurological disease caused by abnormal discharges of brain neurons. Patients often experience symptoms such as loss of consciousness and limb convulsions during an epilepsy. Currently, drug inhalation is often used in clinical practice to intervene in acute episodes, and the drug is quickly absorbed through the nasal mucosa to achieve a sedative and antispasmodic effect. There are many inhalation and olfactory therapy devices in the prior art, and their typical structures include a drug storage chamber, a gas suction unit, and an atomizing nozzle. When in use, the device is inserted into the patient's nasal cavity, and an airflow is formed by sucking external air to push the liquid or atomized drug deep into the nasal cavity.

[0003] However, existing sniffing devices have been found to have significant defects in clinical applications: since the device continuously draws in external air during operation, the original oxygen supply in the patient's nasal cavity is partially blocked by the airflow of the medicine. During an epileptic seizure, the patient's respiratory system is often in an unstable state. At this time, the nasal passage is occupied by the sniffing device, which reduces the efficiency of oxygen intake and easily leads to a decrease in blood oxygen saturation. Especially in long-term treatment or critically ill patients, hypoxia may increase the risk of brain damage. In addition, some devices use a closed design to improve the efficiency of drug delivery, but it will completely block the exchange of gases between the nasal cavity and the outside world, further exacerbating the problem of insufficient oxygen supply.

[0004] The inventor of this case considered opening vents on the side wall of the olfactory suction device to maintain oxygen supply. However, this type of design has two problems: on the one hand, it is difficult to coordinate the flow of the vents and the drug channel, and the oxygen supplement is insufficient; on the other hand, impurities in the outside air may enter the patient's respiratory tract through the vents. The inventor also considered integrating an independent oxygen supply line into the olfactory suction device, but this will significantly increase the size of the device, affect the comfort of nasal insertion, and there is a risk of cross-contamination of the line. Therefore, how to achieve coordinated control of drug delivery and oxygen supply without increasing the complexity of the device has become a technical problem that needs to be solved urgently in this field.

[0005] It is particularly emphasized that the methods described in this section are not necessarily methods that have been previously conceived or adopted. Unless otherwise specified, it should not be assumed that any method described in this section is considered to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to have been recognized in any prior art. Summary of the invention

[0006] Aiming at the problem that the existing epilepsy sniffer device causes insufficient oxygen supply to patients during treatment, the present invention provides a sniffer device that can be connected to a nasal oxygen tube to achieve synchronous delivery of oxygen and medicine.

[0007] To achieve the above object, a technical solution adopted by the present invention is:

[0008] A sniffing device for treating epilepsy includes a medicine sniffing mechanism for sucking gas to push medicine to actively spray into the patient's nasal cavity, and also includes an air source docking mechanism connected to the air inlet end of the medicine sniffing mechanism. The air source docking mechanism can be connected to a nasal oxygen tube. After connection, the nasal cannula of the oxygen supply nasal plug of the nasal oxygen tube will be covered. When the medicine sniffing mechanism sucks gas, the oxygen discharged by the oxygen supply nasal plug will be sucked into the medicine sniffing mechanism to participate in pushing the medicine.

[0009] Furthermore, the air source docking mechanism includes an upper shell, a sliding connection, a lower shell and a first elastic member. The upper end of the upper shell is connected to the air inlet end of the medicine suction mechanism, and the lower end of the upper shell is an open splicing end. The sliding connection is fixed to the upper shell and longitudinally slidably connected to the lower shell. The upper end of the lower shell is an open splicing end that matches the upper shell. The first elastic member is arranged between the lower shell and the sliding connection to push the lower shell to move toward one side of the upper shell.

[0010] Furthermore, the left and right sides of the lower end of the upper shell and the left and right sides of the upper end of the lower shell are provided with receiving grooves for accommodating the horizontal tube of the oxygen supply nasal plug. When the upper shell and the lower shell are assembled with each other, the four receiving grooves are aligned in pairs to form receiving ring grooves for accommodating the left and right ends of the horizontal tube.

[0011] Furthermore, the air source docking mechanism also includes a pulling member connected to the lower shell.

[0012] Furthermore, the pull member is longitudinally sealed and penetrates the lower shell, the pull member is a hollow structure with an upper end opening, and the lower part of the pull member is connected to the external atmosphere through a gas filter;

[0013] The air source docking mechanism further includes a second elastic member, which is disposed between the lower shell and the pulling member to push the pulling member to move toward one side of the upper shell;

[0014] The upper inner portion of the upper shell has a docking sleeve for sealingly docking with the upper end of the pulling member, and the upper shell is connected to the air inlet end of the medicine suction mechanism through the docking sleeve;

[0015] When the medicine sniffing mechanism is not connected to the nasal oxygen tube, the upper end of the pulling member will abut against the lower end of the docking tube under the elastic force of the second elastic member. In this state, the gas sucked by the medicine sniffing mechanism is the gas in the external atmosphere that enters the pulling member after being filtered by the gas filter.

[0016] When the medicine sniffing mechanism is connected to the nasal oxygen tube, the upper shell and the lower shell will be butted against each other under the elastic force of the first elastic member to cover the oxygen supply nasal plug of the nasal oxygen tube, and the upper end of the pulling member will be sealed and abutted against the side of the oxygen supply nasal plug under the elastic force of the second elastic member, thereby closing the upper end of the pulling member. In this state, the gas sucked by the medicine sniffing mechanism is the oxygen discharged by the oxygen supply nasal plug.

[0017] Furthermore, a sealing ring is provided on the outer periphery of the upper end of the pulling member.

[0018] Furthermore, a lower pull ring is provided at the lower end of the pulling member, and upper pull rings are provided on both left and right sides of the upper end of the upper shell.

[0019] Furthermore, the left and right sides of the upper end of the pulling member are provided with a first abutment portion extending laterally, and the second elastic member has two, and the two second elastic members are distributed on the left and right sides of the pulling member, the upper end of the second elastic member abuts against the corresponding first abutment portion, and the lower end abuts against the inner bottom of the lower shell body.

[0020] Furthermore, the upper end of the pulling member is in a concave arc shape that matches the horizontal tube of the oxygen supply nasal plug, and the lower end of the docking tube is in a convex arc shape that matches the upper end of the pulling member.

[0021] Furthermore, the lower shell body has left and right sides internally provided with transversely extending second abutting portions, the lower end of the sliding connection member extends into the lower shell body and has two third abutting portions slidably assembled in the lower shell body, the positions of the two third abutting portions respectively correspond to the positions of the two second abutting portions, the first elastic member has two, the upper end of the first elastic member abuts against the corresponding second abutting portion, and the lower end of the first elastic member abuts against the corresponding third abutting portion.

[0022] The beneficial effects of the present invention are concentrated in the coordinated improvement of treatment safety and operational efficiency: through the intelligent switching of oxygen and air dual-drive modes, the patient's nasal oxygen supply is maintained synchronously during the inhalation and sniffing drug administration process, completely solving the risk of hypoxia caused by blocking the airway of traditional devices; the mechanical linkage design realizes adaptive switching of the gas source to ensure rapid response and uninterrupted treatment in emergency scenarios; the one-handed operation logic and symmetrical elastic structure of the upper and lower pull rings greatly simplify the nasal oxygen tube docking process, while the curved surface sealing and filtering system ensure the cleanliness of the airway to avoid cross contamination; the structural design compatible with existing nasal oxygen tubes does not require the modification of oxygen supply equipment, lowering the threshold for clinical use, and the uniform clamping force and guide limit system improve the reliability of the device in long-term use. While ensuring the efficient delivery of drugs, the overall solution provides a safe and convenient means of respiratory support and treatment coordination for critical cases such as status epilepticus.

DETAILED DESCRIPTION

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

[0031] Reference Figure 1-Figure 4As shown, a suction and sniffing device for treating epilepsy in this embodiment includes a drug suction and sniffing mechanism and an air source docking mechanism 2.

[0032] The medicine sniffing mechanism is not shown in the figure, which is an improved device in the prior art, and contains a medicine storage chamber, an atomization unit and a negative pressure generator. The negative pressure generator sucks the medicine out of the storage chamber and atomizes it through the suction airflow, and finally sprays it into the patient's nasal cavity through the nozzle. The medicine sniffing mechanism is different from the prior art in that the air inlet end of the medicine sniffing mechanism is connected to the air source docking mechanism 2.

[0033] In this embodiment, the gas source docking mechanism 2 can be connected to the nasal oxygen tube 3, and after the connection, the nasal cannula 322 of the oxygen supply nasal plug 32 of the nasal oxygen tube 3 will be covered to form a closed air path. When the medicine sniffing mechanism sucks gas, the oxygen discharged by the nasal cannula 322 will be sucked into the medicine sniffing mechanism to participate in the pushing of the medicine.

[0034] When in use, the gas source docking mechanism 2 is connected to the nasal oxygen tube 3, and then the drug suction mechanism is started, and the internal negative pressure sucks the gas in the gas source docking mechanism 2, that is, the oxygen discharged from the nasal cannula 322 is sucked, so that the oxygen can replace the external air as the power gas source. This design ensures that the patient's nasal cavity is always supplied with oxygen during the treatment process, avoiding the risk of hypoxia caused by traditional suction devices.

[0035] In this embodiment, the air source docking mechanism 2 includes an upper shell 21, a sliding connector 22, a lower shell 23 and a first elastic member 24. The upper end of the upper shell 21 is connected to the air inlet end of the medicine sniffing mechanism, and in this embodiment, it is specifically connected through a hose. The lower end of the upper shell 21 is an open splicing end, and the sliding connector 22 is fixed to the upper shell 21 and longitudinally slidably connected to the lower shell 23, so that the upper shell 21 and the lower shell 23 can slide relative to each other. The upper end of the lower shell 23 is an open splicing end that matches the upper shell 21. When the upper shell 21 and the lower shell 23 slide relative to each other and close, they can be spliced ​​to form a storage space for accommodating the oxygen supply nasal plug 32. The first elastic member 24 is arranged between the lower shell 23 and the sliding connector 22 to push the lower shell 23 to move toward the side of the upper shell 21, so that the upper shell 21 and the lower shell 23 can maintain an elastic closing trend in a natural state.

[0036] When the nasal oxygen tube 3 needs to be connected, the operator pulls down the lower shell 23 to overcome the elastic force of the first elastic member 24 to separate the upper and lower shells. The oxygen supply nasal plug 32 of the nasal oxygen tube 3 is placed between the upper and lower shells, and after releasing the pulling member 25, the first elastic member 24 pushes the lower shell 23 upward, so that the nasal cannula 322 is completely wrapped in the accommodating space.

[0037] In this embodiment, both the left and right sides of the lower end of the upper shell 21 and the left and right sides of the upper end of the lower shell 23 are provided with receiving grooves for receiving the transverse tube 321 of the oxygen supply nasal plug 32. When the upper shell 21 and the lower shell 23 are assembled with each other, the four receiving grooves are aligned in pairs to form receiving ring grooves for receiving the left and right ends of the transverse tube 321. After the air source docking mechanism 2 is connected to the nasal oxygen tube 3, the left and right ends of the transverse tube 321 will be embedded in the corresponding receiving ring grooves, so as to ensure an airtight connection.

[0038] In this embodiment, the gas source docking mechanism 2 further includes a pulling member 25 connected to the lower shell 23. The setting of the pulling member 25 facilitates the user to apply force to the lower shell 23 so as to open the upper and lower shells.

[0039] In this embodiment, the pull member 25 is longitudinally sealed and penetrates the lower housing 23. The pull member 25 is a hollow structure with an upper end opening. The lower part of the pull member 25 is connected to the external atmosphere through the gas filter 251, and the external air can enter the pull member 25 through the gas filter 251. The gas filter 251 can specifically adopt a medical-grade hydrophobic filter membrane to effectively block dust and microorganisms when air is inhaled.

[0040] In this embodiment, the air source docking mechanism 2 further includes a second elastic member 26 , which is disposed between the lower shell 23 and the pulling member 25 to push the pulling member 25 to move toward the upper shell 21 .

[0041] The upper inner portion of the upper shell 21 has a docking tube 211 for sealingly docking with the upper end of the pulling member 25 , and the upper shell 21 is connected to the air inlet end of the medicine aspiration mechanism through the docking tube 211 .

[0042] In a natural state, the second elastic member 26 can keep the pulling member 25 and the docking tube 211 in an elastic closing tendency. When the operator pulls down the pulling member 25, the pulling member 25 will overcome the elastic force of the second elastic member 26 and move downward relative to the lower shell 23. In addition, the second elastic member 26 will also 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 medicine suction mechanism is not connected to the nasal oxygen tube 3, the upper end of the pulling member 25 will abut against the lower end of the docking tube 211 under the elastic force of the second elastic member 26. In this state, the gas sucked by the medicine suction mechanism is the gas in the external atmosphere that enters the pulling member 25 after being filtered by the gas filter 251, so that clean air can be used as the gas source for pushing the medicine.

[0044] When the medicine sniffing mechanism is connected to the nasal oxygen tube 3, the upper shell 21 and the lower shell 23 will be butted against each other under the elastic force of the first elastic member 24 to cover the nasal cannula 322 of the oxygen supply nasal plug 32, and the upper end of the pulling member 25 will be sealed and abutted against the side of the oxygen supply nasal plug 32 under the elastic force of the second elastic member 26, thereby closing the upper end of the pulling member 25. In this state, the gas sucked by the medicine sniffing mechanism is the oxygen discharged from the nasal cannula 322, so that oxygen can be used as the gas source for pushing the medicine.

[0045] The external air drive mode is suitable for scenarios where the patient does not need supplemental oxygen, such as mild attacks, normal spontaneous breathing, or the initial stage of emergency treatment. In this mode, the device pushes the medicine by filtering external air, and can be directly started when operated. It has the advantages of rapid response and easy access to air sources, and is especially suitable for outpatient clinics, homes, or temporary scenarios where oxygen supply equipment is missing.

[0046] The oxygen-driven mode is designed for critically ill patients who need simultaneous oxygen inhalation. When the device is connected to a nasal oxygen cannula, it automatically switches to pumping medical oxygen-driven agents. This mode maintains continuous oxygen delivery through a closed airway and is suitable for high-risk situations such as status epilepticus, respiratory depression, or hypoxia. It can achieve seamless coordination of treatment and oxygen therapy in scenarios such as ICUs and ambulances, avoiding the risk of hypoxia caused by traditional devices blocking nasal ventilation.

[0047] The two modes are automatically switched through mechanical linkage: when the nasal oxygen cannula is not connected, the elastic sealing structure gives priority to guiding the filtered air; after the nasal oxygen cannula is connected, the device uses oxygen pressure to trigger the gas circuit switching to ensure 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 of critically ill patients for synchronous oxygen supply, and significantly improves the safety of treatment and adaptability to scenarios through intelligent adaptation of the gas source.

[0048] In this embodiment, a sealing ring 252 is provided on the outer periphery of the upper end of the pulling member 25 , and its core function is to achieve bidirectional dynamic sealing.

[0049] When the device is connected to the nasal oxygen tube 3, the sealing ring 252 fits tightly against the outer wall of the transverse tube 321 of the oxygen supply nasal plug 32 to form a seal, preventing oxygen from leaking from the gap between the puller 25 and the transverse tube 321. This seal ensures that oxygen is completely guided to the medicine inhalation mechanism.

[0050] When the nasal oxygen tube 3 is not connected, the sealing ring 252 abuts against the lower end of the docking tube 211 to form a seal to prevent unfiltered air from entering the medicine sniffing mechanism directly. At this time, only air purified by the gas filter 251 is allowed to pass through to prevent pollutants from bypassing the filtering link and entering the patient's respiratory tract.

[0051] The sealing ring 252 can be made of medical silicone or fluororubber, and its elastic properties can buffer the mechanical impact when the pulling member 25 contacts the cross tube 321 / the docking tube 211, thereby reducing the wear of the components.

[0052] A lower pull ring 253 is provided at the lower end of the pull member 25, and upper pull rings 212 are provided on both sides of the upper end of the upper shell 21. Medical staff can insert their thumb into the lower pull ring 253, and their index and middle fingers into the two upper pull rings 212, and then apply force to the opposite sides at the same time, so that the nasal oxygen tube can be docked and separated with one hand through the cooperation of the lower pull ring 253 and the upper pull ring 212, so as to quickly operate and save emergency time (such as quickly completing oxygen supply and drug administration within the golden 5 minutes of epileptic seizure). The symmetrical design of the upper and lower pull rings forms an intuitive operation logic and reduces the risk of misoperation.

[0053] The left and right sides of the upper end of the pulling member 25 are both provided with a first abutment portion 254 extending laterally. There are two second elastic members 26, 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 abutment portion 254, and the lower end abuts against the inner bottom of the lower shell 23. This technical solution achieves precise force control through a symmetrically distributed elastic support structure. The first abutment portions 254 on the left and right sides of the pulling member 25 serve as the force fulcrum of the second elastic member 26. The symmetrical layout of the two second elastic members 26 can evenly transmit elastic force, ensuring that the pulling member 25 maintains vertical stability when moving up and down, and avoiding sealing failure or component jamming caused by unilateral deflection.

[0054] The upper end of the pulling member 25 is in a concave arc shape that matches the transverse tube 321 of the oxygen supply nasal plug 32, and the lower end of the docking tube 211 is in a convex arc shape that matches the upper end of the pulling member 25. This technical solution achieves sealing optimization through curved surface matching design. The concave arc at the upper end of the pulling member 25 precisely matches the outer contour of the transverse tube 321 of the oxygen supply nasal plug 32, forming a stable contact seal when the nasal oxygen tube is connected. The convex arc at the lower end of the docking tube 211 forms a hyperbolic sealing pair with the concave surface of the pulling member 25, which fits tightly in the air drive mode to prevent the infiltration of unfiltered air.

[0055] The lower shell 23 is provided with a second abutting portion 231 extending laterally on both the left and right sides inside. The lower end of the sliding connector 22 extends into the lower shell 23 and is provided with two third abutting portions 221 slidably assembled in the lower shell 23. The positions of the two third abutting portions 221 correspond to the positions of the two second abutting portions 231 respectively. The first elastic member 24 has two. The upper end of the first elastic member 24 abuts against the corresponding second abutting portion 231, and the lower end of the first elastic member 24 abuts against the corresponding third abutting portion 221. This technical solution achieves stable closure and precise resetting of the shell through a symmetrical elastic guide structure. The second abutting portion 231 inside the lower shell 23 and the third abutting portion 221 of the sliding connector 22 form a sliding guide rail. The two first elastic members 24 are arranged on the left and right sides, with the upper end pushing the second abutting portion and the lower end supporting the third abutting portion, forming a bidirectional elastic support system. This design ensures that the lower shell 23 always moves along a fixed trajectory during the up and down sliding process, avoiding shell misalignment or airtight failure caused by deflection; the symmetrically distributed elastic parts evenly distribute the closing pressure, ensuring that the clamping force on the nasal oxygen tube 3 is uniform when the upper and lower shells 21 / 23 are assembled, preventing tube deformation or oxygen leakage caused by unilateral overload.

[0056] In summary, the present invention achieves safe coordination between olfactory therapy and oxygen therapy through innovative gas path integration design without changing the existing nasal oxygen tube structure. Compared with traditional devices, it can effectively increase blood oxygen concentration at the same dosage, and is particularly suitable for patients with status epilepticus accompanied by respiratory depression.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
