Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a laryngeal mask for bronchoscopic diagnosis and treatment. Background Art

[0002] When rescuing patients with cardiac and respiratory arrest or cardiopulmonary resuscitation, it is necessary to establish an effective artificial airway to rescue the patient as soon as possible. When performing surgery on anesthetized patients, in order to maintain the patient's breathing and ventilation, a laryngeal mask is needed to establish an artificial airway to ensure the patient's breathing. The laryngeal mask has been widely used in surgical anesthesia and rescue of critically ill patients.

[0003] Patients sometimes need to insert a bronchoscope for related examinations. During the use of the existing single-airway laryngeal mask, the airway of the laryngeal mask is connected to the ventilator, and the bronchoscope cannot be inserted into the laryngeal mask for use, which affects the first aid and treatment of the patient. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a laryngeal mask for bronchoscopic diagnosis and treatment. The bronchoscope is passed through the mask body, and medical staff examines the patient through the bronchoscope. The laryngeal mask can be used to provide oxygen to the patient and the bronchoscope can be used to examine the patient, thereby facilitating first aid and treatment of the patient.

[0005] The utility model provides a laryngeal mask for bronchoscopic diagnosis and treatment, comprising a mask body, wherein the mask body is integrally formed with a ventilation tube connected to the mask body, one end of the ventilation tube away from the mask body is connected with a connector with a three-way arrangement, a side of the connector close to the ventilation tube is integrally formed with a first connecting tube plugged with the ventilation tube, and a second connecting tube connected to a ventilator is integrally formed in the middle of the connector.

[0006] By adopting the above technical solution, the mask body is placed at the patient's throat, the second connecting tube is connected to the ventilator, the oxygen generated by the ventilator passes through the connecting head and the ventilation tube to provide oxygen supply to the patient, the bronchoscope is inserted into the ventilation tube from the side of the connecting head away from the ventilation tube, the bronchoscope is passed out from the mask body, and the medical staff examines the patient through the bronchoscope, which has the effect of not only using the laryngeal mask to provide oxygen to the patient but also using the bronchoscope to examine the patient, thereby facilitating first aid and treatment of the patient.

[0007] Furthermore, a sealing ring that is in close contact with the bronchoscope is fixedly connected to a side of the connector away from the ventilation tube, and the sealing ring is provided with a through hole for the bronchoscope to pass through.

[0008] By adopting the above technical solution, the bronchoscope is tightly plugged into the through hole, and the sealing ring seals the connector, thereby reducing the possibility of air leakage in the connector and ensuring the oxygen supply effect for the patient.

[0009] Furthermore, a sealing pad tightly plugged with the bronchoscope is fixedly connected to the inner wall of the connector near the sealing ring, and the sealing pad is provided with a connecting hole for the bronchoscope to pass through.

[0010] By adopting the above technical solution, the sealing gasket is placed between the second connecting tube and the sealing ring, the bronchoscope is tightly plugged into the connecting hole, oxygen enters the connecting head, the sealing gasket and the bronchoscope are always in contact with each other, thereby further increasing the sealing performance and reducing the possibility of leakage of gas inside the connecting head from the side of the connecting head away from the ventilation tube, thereby ensuring oxygen supply to the patient.

[0011] Furthermore, the sealing pad is gradually closed along the direction of insertion of the bronchoscope.

[0012] By adopting the above technical solution, when the bronchoscope passes through the connecting hole, the sealing gasket can guide the bronchoscope so that the bronchoscope passes through the connecting hole more smoothly, and the sealing gasket is gradually closed toward the middle position along the insertion direction of the bronchoscope, which can further increase the sealing performance when the sealing gasket and the bronchoscope are in contact, and further reduce the possibility of gas leakage from the connection between the bronchoscope and the sealing gasket.

[0013] Furthermore, a protective gasket is fixedly connected to the outer wall of the ventilation pipe.

[0014] By adopting the above technical solution, the protective gasket is placed at the position of the patient's teeth. The protective gasket can support the ventilation tube, reduce the possibility of the ventilation tube being folded due to the patient biting the ventilation tube, and ensure that oxygen can pass through the ventilation tube smoothly to provide oxygen supply to the patient.

[0015] Furthermore, the protective gasket is a protective gasket whose hardness gradually decreases from the inside to the outside.

[0016] By adopting the above technical solution, the inner part of the protective gasket is harder and can support the ventilation tube, reducing the possibility of the ventilation tube being folded due to the patient biting the ventilation tube. The outer part of the protective gasket is softer, which is beneficial for protecting the patient's teeth when the patient bites the ventilation tube.

[0017] Furthermore, the first connecting pipe is tightly plugged into the inner wall of the ventilation pipe.

[0018] By adopting the above technical solution, the first connecting pipe is tightly plugged into the inner wall of the ventilation pipe. Compared with the ventilation pipe being tightly plugged into the inner wall of the ventilation pipe, the possibility of the ventilation pipe end being compressed and causing a decrease in oxygen flow is reduced, thereby ensuring the amount of oxygen entering the ventilation pipe.

[0019] Furthermore, a sealing ring arranged around the first connecting pipe is fixedly connected to the outer wall of the first connecting pipe, and the sealing ring is tightly plugged into the inner wall of the ventilation pipe.

[0020] By adopting the above technical solution, the sealing ring increases the sealing performance when the first connecting pipe and the ventilation pipe are plugged in.

[0021] Furthermore, a sealing groove for inserting a sealing ring is provided on the inner wall of the ventilation pipe.

[0022] By adopting the above technical solution, the sealing ring is plugged into the sealing groove, which increases the sealing performance when the first connecting pipe and the ventilation pipe are plugged in, and can also increase the stability of the plugging of the first connecting pipe and the ventilation pipe, reducing the possibility of separation of the ventilation pipe and the first connecting pipe.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] (1) The mask body is placed at the throat of the patient, and the second connecting tube is connected to the ventilator. The oxygen generated by the ventilator passes through the connector and the ventilation tube to provide oxygen supply to the patient. The bronchoscope is inserted into the ventilation tube from the side of the connector away from the ventilation tube. The bronchoscope is passed out of the mask body, and the medical staff examines the patient through the bronchoscope. The laryngeal mask can be used to provide oxygen to the patient and the bronchoscope can be used to examine the patient, which is convenient for first aid and treatment of the patient.

[0025] (2) The bronchoscope is tightly plugged into the through hole, and the sealing ring seals the connector to reduce the possibility of air leakage in the connector and ensure the oxygen supply effect for the patient.

[0026] (3) The inner part of the protective gasket is relatively hard, which can support the ventilation tube and reduce the possibility of the ventilation tube being folded due to the patient biting the ventilation tube. The outer part of the protective gasket is relatively soft, which is beneficial for protecting the patient's teeth when the patient bites the ventilation tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0034] The following is combined with Figure 1 To Attachment Figure 4 And specific embodiments describe the present invention in detail.

[0035] like Figures 1 to 3 As shown, the utility model provides a laryngeal mask for bronchoscopic diagnosis and treatment, comprising a mask body 1, the mask body 1 is integrally formed with a ventilation tube 2, and the ventilation tube 2 is connected to the mask body 1. A three-way connector 3 is connected to one end of the ventilation tube 2 away from the mask body 1, and a first connecting tube 31 is integrally formed on the side of the connector 3 close to the ventilation tube 2. The first connecting tube 31 is inserted into the end of the ventilation tube 2 away from the mask body 1, and the first connecting tube 31 is tightly plugged with the ventilation tube 2.

[0036] The side surfaces of the connector 3 close to the ventilation pipe 2 and away from the ventilation pipe 2 are both opened, and the middle side wall of the connector 3 is also opened.

[0037] A second connecting pipe 32 is integrally formed at the middle opening of the connector 3, and the second connecting pipe 32 is connected to the air outlet of the ventilator (not shown in the figure), and the air outlet of the ventilator is inserted into the second connecting pipe 32, and the air outlet of the ventilator is tightly plugged into the second connecting pipe 32. The oxygen generated by the ventilator passes through the second connecting pipe 32, the connector 3, the first connecting pipe 31 and the ventilation tube 2 in sequence to provide oxygen supply to the patient.

[0038] The bronchoscope 4 is inserted from the side of the connector 3 away from the ventilation tube 2. The end of the bronchoscope 4 passes through the connector 3 and the ventilation tube 2 and then comes out of the cover body 1. The inner diameter of the ventilation tube 2 is larger than the outer diameter of the bronchoscope 4. Medical staff perform relevant examinations on the patient through the bronchoscope 4.

[0039] The ventilator is connected to the second connecting tube 32, and the bronchoscope 4 is placed inside the ventilation tube 2. Oxygen is provided to the patient after passing through the ventilation tube 2. Medical staff examine the patient through the bronchoscope 4. It has the effect of not only using the laryngeal mask to provide oxygen to the patient but also using the bronchoscope 4 to examine the patient, which is convenient for first aid and treatment of the patient.

[0040] like Figures 1 to 3 As shown, a sealing ring 5 is fixedly connected to the side of the connector 3 away from the ventilation tube 2, and a through hole 51 is provided in the middle of the sealing ring 5, and the through hole 51 runs through the sealing ring 5. The bronchoscope 4 passes through the through hole 51 and is tightly plugged into the through hole 51. The sealing ring 5 seals the side of the connector 3 away from the ventilation tube 2, reducing the possibility of air leakage of the connector 3 and ensuring the oxygen supply effect to the patient.

[0041] The inner wall of the connector 3 is fixedly connected with a sealing gasket 6, which is arranged around the inner wall of the connector 3 and is formed into a truncated cone shape. The sealing gasket 6 is gradually closed toward the middle position along the insertion direction of the bronchoscope 4. A connecting hole 61 is arranged in the middle of the sealing gasket 6. The bronchoscope 4 is inserted into the ventilation tube 2 after passing through the connecting hole 61, and the bronchoscope 4 is tightly plugged into the connecting hole 61. The sealing gasket 6 is placed between the middle opening of the connector 3 and the sealing ring 5. Oxygen enters the connector 3, and the sealing gasket 6 is always in contact with the bronchoscope 4, which further increases the sealing performance and reduces the possibility of leakage of the internal gas of the connector 3 from the side of the connector 3 away from the ventilation tube 2, thereby ensuring the oxygen supply to the patient.

[0042] The sealing gasket 6 is gradually closed toward the middle position along the insertion direction of the bronchoscope 4. When the bronchoscope 4 passes through the connecting hole 61, the truncated cone-shaped sealing gasket 6 can guide the bronchoscope 4, so that the bronchoscope 4 can pass through the connecting hole 61 more smoothly. At the same time, the sealing gasket 6 is gradually closed toward the middle position along the insertion direction of the bronchoscope 4, which can further increase the sealing performance when the sealing gasket 6 and the bronchoscope 4 are in contact, and further reduce the possibility of gas leakage from the connection between the bronchoscope 4 and the sealing gasket 6.

[0043] A protective gasket 7 is fixedly sleeved on the outer wall of the ventilation tube 2. The hardness of the protective gasket 7 gradually decreases from the inside to the outside in the radial direction. The protective gasket 7 is placed at the position of the patient's teeth. The inside of the protective gasket 7 is harder and can support the ventilation tube 2, reducing the possibility of the ventilation tube 2 being folded due to the patient biting the ventilation tube 2. The outside of the protective gasket 7 is softer, which is beneficial to protecting the patient's teeth when the patient bites the ventilation tube 2.

[0044] like Figure 2 and Figure 4 As shown, a sealing ring 311 is fixedly connected to the outside of the first connecting pipe 31, and the sealing ring 311 is arranged around the outer wall of the second connecting pipe 32. A sealing groove 21 is arranged around the inner wall of the vent pipe 2 at the connecting end of the vent pipe 2 and the first connecting pipe 31.

[0045] When the first connecting tube 31 is plugged into the ventilation tube 2, the sealing ring 311 is tightly plugged into the sealing groove 21, which increases the sealing performance when the first connecting tube 31 and the ventilation tube 2 are plugged in. At the same time, the plugging of the sealing ring 311 and the sealing groove 21 can also increase the stability of the plugging of the first connecting tube 31 and the ventilation tube 2, and reduce the possibility of separation of the ventilation tube 2 and the first connecting tube 31.

[0046] The implementation principle of the laryngeal mask for bronchoscopic diagnosis and treatment provided by the utility model is: the mask body 1 is placed on the patient's throat, the second connecting tube 32 is connected to the ventilator, and the bronchoscope 4 is passed through the through hole 51, the connecting hole 61 and the ventilation tube 2 in sequence and then passes through the mask body 1. The laryngeal mask can ensure oxygen supply to the patient while the medical staff can also perform relevant examinations on the patient through the bronchoscope 4.

[0047] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
