Description

A Subglottic Suction and Irrigation Endotracheal Tube Device

technical field

The utility model belongs to the field of medical auxiliary devices, in particular to a subglottic suction and flushing trachea catheter device.

Background technique

In the rescue and treatment of critically ill patients, tracheotomy and tracheotomy are often required. Above the air bag of the tracheotomy tube, saliva and reflux and aspiration often accumulate. These retained fluids often become a new source of infection or these liquids flow into the lungs along the gap between the air bag and the tracheal wall, resulting in Lung infection worsens. There are many types of existing tracheotomy tubes. Among them, the subglottic suction tracheotomy tube can absorb the secretions above the air bag. The principle is to place a suction tube on the outer wall of the tracheotomy tube, and draw The secretion is sucked out, but there are still the following disadvantages. The suction tube usually has only one opening. When the secretion is thick, or when there is sputum scab, the suction tube is easy to be blocked, and the suction cannot be continued. Thereby damaging the tracheal mucosa and increasing the patient's discomfort.

In order to solve the above problems, the Chinese Patent Publication No. CN215135297U discloses a sustainable subglottic irrigation and suction gas cutting sleeve, which includes a gas cutting sleeve body and a continuous subglottic irrigation and suction device. The front end is covered with an air bag, and the subglottic continuous irrigation and suction device includes an outer sleeve, an inner core tube and an irrigation tube, and the irrigation tube is close to the outer sleeve, and both are located on the outer wall of the tracheotomy sleeve body. One end of the flushing pipe is provided with a cover, the cover is provided with a joint, and the air bag is provided with an inflatable component for inflating the air bag. The utility model has a simple structure, and by designing the outer casing, the inner core pipe and the flushing pipe, it can Continuous subglottic flushing and suction ensures adequate drainage of subglottic secretions and reflux, while avoiding damage to the tracheal mucosa due to excessive negative pressure, and is easy to use.

However, after rinsing the tracheal wall, deflate the balloon and then take out the device, flushing liquid or secretions may remain on the tracheal wall, and the device is not convenient for collecting the residual flushing liquid or secretions. Flushing fluid or secretions may flow down the tracheal wall, causing downstream infection of the flushing fluid or secretions, and the device is not convenient for collecting the suctioned flushing fluid or secretions, so it is necessary to set up a subglottic suction and irrigation tracheal tube device.

Utility model content

In order to solve the above problems, the utility model proposes a subglottic suction and flushing endotracheal catheter device to facilitate the collection of flushing fluid or secretions, and to avoid downward infection of flushing fluid or secretions.

In order to achieve the above object, the technical scheme of the utility model is as follows: a subglottic suction and flushing endotracheal catheter device, including a catheter, an infusion tube and a gas delivery tube are bonded inside the catheter, a balloon is placed over the catheter, and the bottom of the balloon is bonded to the outside of the catheter On the wall, there is a gap between the upper part of the airbag and the catheter, one end of the air delivery tube runs through the catheter and communicates with the air bag, and the other end of the air delivery tube is connected with an air delivery component; one end of the infusion tube runs through the catheter, and the other end of the infusion tube is connected with a collection component; Including the collection bottle, the thread on the mouth of the collection bottle is matched with a bottle cap, the infusion tube runs through the bottle cap, the bottle cap is connected with a negative pressure suction tube, and the negative pressure suction tube is connected with a negative pressure pump; the infusion tube is also connected with an infusion component, and the infusion The assembly includes a branch pipe, a valve is arranged near the branch pipe of the infusion pipe, a syringe is connected to the end of the branch pipe far away from the infusion pipe, a three-way valve is connected to the straight pipe, and a suction pipe is connected to the three-way valve.

After the device is completely taken out of the patient's body, the Flush fluid or secretions and pour them out. Thus, it is convenient to collect the flushing liquid or secretion remaining on the inner wall of the trachea, and the problem of descending infection of the flushing liquid or secretion is avoided.

Further, the infusion tube and the branch tube are integrally formed.

Beneficial effect: the integral molding has good sealing performance, and the occurrence of leakage is avoided.

Further, a sealing ring is glued inside the bottle cap.

Beneficial effect: the sealing ring enhances the airtightness between the bottle cap and the collection bottle, and prevents the collection bottle from leaking.

Further, a rubber head is fixedly connected to one end of the catheter, and a round port is provided on the rubber head.

Beneficial effect: the rubber head can prevent the catheter from scratching the inner wall of the trachea when it enters the trachea.

Further, a first scale mark is engraved on the outer wall of the catheter. There is a second graduation mark on the collection bottle.

Beneficial effects: the first scale line can facilitate observation of the length of the catheter entering the trachea; the second scale line can facilitate observation of the amount of flushing liquid or secretion collected.

Further, the air delivery component is an air pump, and the air pump is connected with the air delivery pipe.

Beneficial effect: the air pump can conveniently inflate and deflate the air bag.

Further, the end of the conduit away from the rubber head is connected with a joint.

Beneficial effect: the joint can be conveniently connected with other equipment.

Further, the syringe includes a cylinder, which communicates with the branch pipe, and a piston is slidably fitted in the cylinder, and a connecting rod is fixedly connected to the side of the piston away from the branch pipe, and a handle is fixedly connected to the connecting rod.

Beneficial effect: when using the syringe, the handle can be held, pulled or pushed the connecting rod, so that the piston slides in the cylinder, and the cleaning fluid can be sucked or squeezed.
