Description

Splash-proof tracheal tube

technical field

The utility model relates to a structure of a medical device, in particular to a spray-proof trachea catheter.

Background technique

Endotracheal tube (or "tracheal intubation") is an instrument used to effectively ensure the smooth airway of patients during diagnosis and treatment. It is widely used in patients who are in a coma or anesthesia, or in rescue. Endotracheal catheterization can quickly establish an artificial airway and ensure oxygen supply and carbon dioxide discharge. It is an indispensable basic technology in modern anesthesiology and modern emergency medicine, and plays a key role in the rescue and treatment of critically ill patients and cardiopulmonary resuscitation. The opening of the existing tracheal tube is open upwards, such as the structure of "tracheal intubation" shown in Chinese patent CN201520991208.4, although it can ensure that the patient's breathing is smooth, it is easy to release secretions such as sputum when exhausting or coughing. Splashing out will cause medical environment pollution or cross-infection, and greatly increase the occupational exposure of medical staff; the structure of the "Multifunctional Double-bag Endotracheal Tube" shown in Chinese patent CN201510403923.6 increases the side channel for sucking sputum, However, the opening of the catheter is still at an upward angle, and the patient is still prone to sputum ejection when coughing.

Contents of the invention

The utility model aims at proposing a structure of an anti-splash trachea catheter, which can better reduce the pollution of the medical environment caused by the splash.

The splash-proof tracheal catheter includes a catheter body, an inclined tube mouth, an air bag, a catheter connector, a catheter side connector and a connector cover. The inclined nozzle is located at the lower end of the catheter body, the air bag is located at the lower part of the catheter body, the catheter connector is connected to the upper end of the catheter body, the upper end of the catheter connector is the positive opening of the catheter connector, the catheter side connector is located on the side wall of the catheter connector, and the catheter side connector is inclined Stretching downwards, the outer diameter of the main opening of the conduit joint is the same as that of the conduit side joint; the joint cover is connected with the outer pipe wall of the conduit joint through a joint cover connecting rope.

The joint cover of the anti-splash trachea conduit can be covered on the positive opening of the conduit joint or on the outlet of the conduit side joint, all of which can keep sealing. After the splash-proof tracheal tube is correctly inserted into the patient's respiratory tract, when the tracheal tube is not connected to the ventilator, cover the front of the tube connector with a connector cover to keep it sealed, the outlet of the connector on the catheter side is unblocked, and the outlet of the connector on the catheter side is open. The direction is obliquely downward, which greatly reduces the possibility of sputum splashing to medical staff. When the catheter connector is connected to the ventilator, the outlet of the catheter side connector is covered with a connector cover to keep it sealed.

detailed description

As shown in FIG. 1 , this splash-proof tracheal catheter includes a catheter body 13 , an inclined nozzle 11 , an air bag 12 , a catheter connector 1 , a catheter side connector 2 and a connector cover 4 . The inclined nozzle 11 is located at the lower end of the catheter body 13, the balloon 12 is located at the lower part of the catheter body, the catheter joint 12 is connected to the upper end of the catheter body, the upper end of the catheter joint 1 is the front mouth 3 of the catheter joint, and the catheter side joint 2 is located at the bottom of the catheter joint 1. On the side wall, the conduit-side connector 2 extends obliquely downward, that is, the inclination angle a is an obtuse angle. The outer diameter of the conduit joint positive opening 3 is the same as that of the conduit side joint 2; the joint cover 4 is connected to the outer pipe wall of the conduit joint 1 by a joint cover connecting rope 8. Because the outer diameter of conduit joint positive opening 3 is identical with the external diameter of conduit side joint 2, joint cover 4 both can cover on conduit joint positive opening 3, also can cover on the outlet of conduit side joint 2, all can keep sealing. 9 is an inflatable tube among Fig. 1, and 10 is a Murphy hole.

As shown in Figure 2, the center of the bottom surface of the joint cover 4 in this splash-proof tracheal conduit can have a cover mouth 14, and the diameter of this cover mouth is greater than the outer diameter of the sputum suction pipe, as shown in Figure 1, the joint cover There is a cover plug connecting rope 7 on the outer wall of 4, and the end of cover plug connecting rope 7 is connected with a cover plug 6. When using the joint cover 4 to seal the outlet of the conduit joint positive opening 3 or the conduit side joint 2, the cover plug 6 is inserted into the cover opening 14 on the bottom surface of the joint cover 4 to keep it sealed. When more sputum occurs in the catheter body, the cover plug 6 can be opened, and the sputum suction tube can be inserted for sputum suction.

As shown in Fig. 2 and Fig. 3, the inboard of the cover opening 14 of the joint cover 4 in this anti-splash tracheal catheter can also have a one-way valve 5, and the number of petals of the one-way valve is more than three, as shown in Fig. There are four petals in the middle, and the maximum opening diameter of the one-way valve is greater than the outer diameter of the sputum suction tube. The one-way valve opens into the catheter and closes when outward force is applied. With this structure, when inserting the sputum suction tube for sputum suction treatment, the sputum suction tube needs to be pushed open and then inserted into the catheter. The one-way valve can ensure that medical staff can avoid being splashed by sputum during the sputum suction operation. The anti-splash effect is even better.

The material of all parts in the anti-splash tracheal catheter can be medical rubber or polyethylene plastic, and the inclination angle a can be 110°-140°.
