Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a tracheal intubation device with a structure for preventing droplet pollution. Background Art

[0002] Tracheal intubation is mainly used to assist patients in breathing, relieve airway obstruction, and absorb airway secretions. When patients need to undergo general anesthesia surgery, or suddenly stop breathing and cannot breathe independently, or their airways are compressed, or there are too many airway secretions that cannot be cleared by themselves, resulting in airway obstruction, they will experience symptoms such as difficulty breathing, shortness of breath, cyanosis of the lips, headache and fatigue. In this case, tracheal intubation is needed in a timely manner to assist breathing and improve hypoxia.

[0003] For example, the Chinese patent "CN115300740B Universal Tracheal Cannula" includes a cannula assembly and an inflation monitoring assembly; the cannula assembly includes a cannula body, a first air bag arranged at the insertion end of the cannula body, a first air inlet pipe connected to the first air bag, a second air bag arranged on at least part of the outer periphery of the cannula body, and a second air inlet pipe connected to the second air bag; the inflation monitoring assembly is connected to the first air inlet pipe and the second air inlet pipe, and is used to collect the first air pressure of the first air bag when inflating the first air bag, and when the first air pressure reaches the set condition, set the pressure lower than the first air pressure to inflate the second air bag; the inner diameter of the cannula can be adjusted according to demand to improve the versatility and fixation efficiency of the tracheal cannula.

[0004] The endotracheal tubes currently used in existing medical institutions lack effective protection in actual applications and generally only have the effect of assisting patients' breathing. During the intubation operation, the endotracheal tube will constantly stimulate the throat wall and glottis. Some patients may cough, causing the droplets produced by the cough to contaminate the air guide connector. Some of the virus droplets carried by the droplets float into the air, causing air pollution. Summary of the invention

[0005] The present disclosure relates to an endotracheal intubation device with a structure to prevent droplet pollution, which solves the problem that the endotracheal intubation used in existing medical treatment lacks effective protection in actual application and generally only has the effect of assisting patients' breathing. During the intubation operation, the endotracheal intubation will continuously stimulate the throat wall and glottis, and some patients may cough, causing the droplets generated by the cough to contaminate the position of the air guide connection head, and some droplets carrying viruses float into the air, causing air pollution.

[0006] In the first aspect of the present disclosure, a tracheal intubation device with a structure for preventing droplet contamination is provided, specifically including: a gas conduction intubation tube, a gas conduction connector, a protective plug, a movable limiting sleeve, and a protective movable sleeve; the end of the gas conduction intubation tube is connected to the gas conduction connector, and the gas conduction connector is connected to a ventilator; a protective plug is connected inside the gas conduction connector, the inside of the protective plug is in a communicating state, the outside of the protective plug is sleeved with a movable limiting sleeve, and the movable limiting sleeve is in contact with the gas conduction connector; the outside of the movable limiting sleeve is connected to a protective movable sleeve, and the protective movable sleeve is in contact with the gas conduction connector.

[0007] Further, the protective plug is inserted into the gas conduction connector. A clamping groove is provided inside the gas conduction connector, and the clamping groove is L-shaped. A clamping block is provided outside the protective plug, and the clamping block is connected to the clamping groove provided in the gas conduction connector. When the protective plug is inserted into the inside of the gas conduction connector, the clamping block is connected to the clamping groove, and the protective plug is connected to the inside of the gas conduction connector by a clamping method, achieving a protective effect on the inside of the gas conduction connector.

[0008] Further, the movable limiting sleeve is slidably connected to the protective plug. A guiding block is provided outside the protective plug, and a movable hole is provided inside the movable limiting sleeve. The guiding block is slidably connected to the movable hole provided in the movable limiting sleeve. Through the sliding fit between the guiding block and the movable hole, a guiding effect on the movement of the movable limiting sleeve outside the protective plug is achieved.

[0009] Further, a positioning plug is provided outside the movable limiting sleeve, and the positioning plug and the clamping block are in different phases. The positioning plug is inserted into the clamping groove provided in the gas conduction connector.

[0010] Further, a return spring is sleeved outside the protective plug. One end of the return spring is in contact with the protective plug, and the other end of the return spring is in contact with the movable limiting sleeve. Through the action of the return spring, elastic reset of the movable limiting sleeve can be realized. When the clamping block moves to the innermost end of the clamping groove, the notch of the clamping groove corresponds to the position of the positioning plug. Under the thrust of the return spring, the movable limiting sleeve will reset, causing the positioning plug to be inserted into the clamping groove, and using the movable limiting sleeve to fix the protective plug, effectively preventing the reverse rotation of the protective plug.

[0011] Further, the inner side of the protective movable sleeve is in contact with the outer side of the gas conduction connector. A linkage convex block is provided outside the movable limiting sleeve, and a connecting hole is provided inside the protective movable sleeve. The linkage convex block is connected to the connecting hole provided in the protective movable sleeve. When the movable limiting sleeve moves and resets under the thrust of the return spring, the movable limiting sleeve will drive the protective movable sleeve to move synchronously, enabling the protective movable sleeve to be tightly sleeved outside the gas conduction connector, thereby providing an effective external protection effect, preventing droplet contamination of the outside of the gas conduction connector, and ensuring the cleanliness of the gas conduction connector.

[0012] Furthermore, a foam-blocking membrane is arranged in a surrounding shape on the outside of the airway cannula, and the foam-blocking membrane is elliptical.

[0013] Furthermore, an inflatable ring is arranged around the foam-barrier membrane, and an air valve is connected to the outside of the inflatable ring through a hose. When in the storage state, the inflatable ring is in an uninflated state, and the foam-barrier membrane is in a folded state, thereby reducing the occupied space and facilitating storage. When the airway tube is inserted into the patient's respiratory tract, air is inflated into the inflatable ring through the air valve, and the inflatable ring expands. The inflatable ring stretches the foam-barrier membrane, and the foam-barrier membrane blocks the droplets generated by the patient's cough, thereby preventing the viruses carried in the droplets from drifting into the air.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the present invention is in use, when the protective plug is inserted into the interior of the gas guide connector, the clamping block is connected to the clamping groove, and the protective plug is connected to the interior of the gas guide connector by clamping, thereby playing a protective effect on the interior of the gas guide connector and preventing droplets from contaminating the interior of the gas guide connector; the guide block and the movable hole slide together, thereby playing a guiding effect on the movement of the movable limit sleeve outside the protective plug and preventing the movable limit sleeve from twisting.

[0016] In addition, the movable limit sleeve can be elastically reset through the action of the reset spring. When the clamping block moves to the innermost end of the clamping groove, the notch of the clamping groove corresponds to the position of the positioning block. Under the thrust of the reset spring, the movable limit sleeve will reset, so that the positioning block is inserted into the clamping groove. The movable limit sleeve is used to fix the protective plug, which effectively prevents the protective plug from rotating in the opposite direction, thereby ensuring that the connection between the protective plug and the gas guide connector is more stable and reliable; when the movable limit sleeve is moved and reset by the thrust of the reset spring, the movable limit sleeve will drive the protective looper to move synchronously, so that the protective looper can be tightly fitted on the outside of the gas guide connector, thereby providing effective The external protection effect can prevent droplets from contaminating the outside of the gas connector and ensure the cleanliness of the gas connector; when the gas connector needs to be connected to the ventilator, the protective loop is moved in the opposite direction, and the protective loop drives the movable limit sleeve to move in the opposite direction synchronously, the reset spring is forced to shrink, and the positioning block is separated from the card slot, and then the protective loop is rotated, and the protective loop drives the movable limit sleeve to rotate synchronously, and the movable limit sleeve drives the protective plug to rotate synchronously, so that the positioning block moves to the notch of the card slot, and the protective plug can be separated from the inside of the gas connector, so that the gas connector can be connected to the ventilator. All steps are designed to be simple and intuitive, ensuring that medical staff can complete the operation quickly and accurately, and the operation is easy.

[0017] In addition, when stored, the inflatable ring is in an uninflated state and the foam barrier membrane is in a folded state, which reduces the space occupied and facilitates storage. When the airway tube is inserted into the patient's respiratory tract, air is inflated into the inflatable ring through the air valve, the inflatable ring expands, and the inflatable ring stretches the foam barrier membrane. The foam barrier membrane blocks the droplets generated by the patient's cough, preventing the viruses carried in the droplets from drifting into the air and polluting the air.

[0045] By adopting the above technical solution, when in storage, the inflatable ring 102 is in an uninflated state and the foam-blocking membrane 101 is in a folded state, which reduces the occupied space and facilitates storage. When the airway tube 1 is inserted into the patient's respiratory tract, air is inflated into the inflatable ring 102 through the air valve 103, the inflatable ring 102 expands, and the inflatable ring 102 opens the foam-blocking membrane 101. The foam-blocking membrane 101 blocks the droplets generated by the patient's cough, preventing the viruses carried in the droplets from drifting into the air and polluting the air.

[0046] Working principle of this embodiment: First, when the protective plug 3 is inserted into the air guide connector 2, the clamping block 301 is connected to the clamping groove 201. The protective plug 3 is connected to the inside of the air guide connector 2 by clamping, providing protection for the inside of the air guide connector 2 and preventing droplet contamination of the inside of the air guide connector 2. The sliding fit between the guiding block 302 and the movable hole 401 guides the movement of the outer movable limit sleeve 4 of the protective plug 3, avoiding the occurrence of torsion of the movable limit sleeve 4. Through the action of the return spring 5, elastic reset of the movable limit sleeve 4 can be achieved. When the clamping block 301 moves to the innermost end of the clamping groove 201, the notch of the clamping groove 201 corresponds to the position of the positioning plug 402. Under the thrust of the return spring 5, the movable limit sleeve 4 will reset, causing the positioning plug 402 to insert into the clamping groove 201, using the movable limit sleeve 4 to fix the protective plug 3, effectively preventing the protective plug 3 from rotating in the reverse direction, thus ensuring a more stable and reliable connection between the protective plug 3 and the air guide connector 2. When it is necessary to connect the air guide connector 2 to the ventilator, move the protective sleeve 6 in the reverse direction. The protective sleeve 6 drives the movable limit sleeve 4 to move synchronously in the reverse direction. The return spring 5 is compressed. The positioning plug 402 separates from the clamping groove 201. Then rotate the protective sleeve 6. The protective sleeve 6 drives the movable limit sleeve 4 to rotate synchronously. The movable limit sleeve 4 drives the protective plug 3 to rotate synchronously, moving the positioning plug 402 to the notch of the clamping groove 201, and the protective plug 3 can be separated from the inside of the air guide connector 2, enabling the air guide connector 2 to be connected to the ventilator. All steps are designed to be simple and intuitive, ensuring that medical staff can complete the operation quickly and accurately. In the storage state, the inflatable ring 102 is in an uninflated state and the droplet-blocking film 101 is in a folded state, reducing the occupied space and facilitating storage. When the air guide tube 1 is inserted into the patient's respiratory tract, the inflatable ring 102 is inflated through the air valve 103. The inflatable ring 102 expands, pushing the droplet-blocking film 101 open. The droplet-blocking film 101 blocks the droplets generated by the patient's coughing at the mouth, preventing the virus carried in the droplets from spreading into the air and contaminating the air.
