Embodiment

[0059] see figure 1 As shown, it is a guide core type anti-tongue fall-back hypoxic catheter provided in this embodiment.

[0060] The anti-tongue fall hypoxic catheter 10 includes a catheter unit 100 , a joint unit 200 and a supporting guide core 300 .

[0061] The catheter unit 100 comprises a hollow hose 110 which can be used for nasopharyngeal ventilation. The hollow hose 100 is a flexible hollow tube, which can be made of flexible materials, such as flexible plastic, rubber, silica gel, resin, etc., preferably a medical PVC tube.

[0062] In this embodiment, the hollow hose 110 has a certain degree of flexibility so that the hollow hose can be bent according to the bending shape of the support guide core 300, and can form a curvature matching the passage of the nasopharyngeal cavity after being inserted into the nasopharyngeal cavity. The bending performance of the hollow hose is related to the flexibility of the hose. When the material of the hose is selected, the flex...

Abstract

The invention discloses a guide core type tongue posterior falling prevention low-oxygen catheter and application, and relates to the technical field of medical instruments. The catheter comprises a catheter unit, a connector unit and a supporting guide core. The catheter unit comprises a hollow hose capable of being used for nasopharynx ventilation; the connector unit comprises a connector head end and a connector tail end, the connector head end is detachably connected with the first connector, and the connector tail end is used for being connected with external equipment; the supporting guide core comprises a second connector and a flexible guide core with flexibility, and the flexible guide core comprises a plurality of movable joint modules which are sequentially connected end to end; during intubation, the soft guide core forms a bent shape matched with the nasopharyngeal cavity by adjusting the connecting angle between the movable joint modules. Steering adjustment is carried out through the soft guide core to guide the catheter to form a matched shape, the nasal mucosa damage and bleeding occurrence rate and the implantation success rate are remarkably reduced, operation is convenient, and external equipment can be conveniently connected.

Description

technical field [0001] The invention relates to the technical field of medical instruments. Background technique [0002] Retro-tongue refers to the symptom that the patient's tongue falls down and blocks the airway when the patient is lying on his back. Among them, in clinical anesthesia, tongue drop is the most common cause of upper airway obstruction. As an example, for example, patients need to be anesthetized during painless gastroenteroscopy, and a certain proportion of patients after anesthesia will experience the symptom of falling tongue; another example, patients are more likely to experience the symptom of falling tongue after general anesthesia; and For example, the topical anesthesia of the oronasal cavity before surgery may also cause symptoms of tongue drop. The symptom of falling back of the tongue is likely to cause the risk of hypoxia because it will block the patient's airway. [0003] In the prior art, the nasopharyngeal airway is usually used to solve...
