Description

Saliva drainage device for trachea cannula

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a saliva drainage device for a trachea cannula.

Background

The trachea cannula is a technology for placing a special airway into a trachea, the technology can provide optimal conditions for airway smoothness, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like, the trachea cannula is usually used in an oral trachea cannula mode, a patient can secrete a large amount of oral water in the oral cavity when the cannula is inserted from the mouth, and because the patient cannot swallow or spit out by himself, secretion is retained in the oral cavity, the cleanness and the sanitation of the oral cavity of the patient are affected, oral infection is easily caused, and basic diseases are aggravated; or the saliva overflows from the mouth of the patient and flows to the neck, clothes, a pillow of a sickbed and the like of the patient, so that the patient is unsanitary, discomfort is caused to the patient, even secondary infection is caused to the patient, and the nursing work intensity of medical staff is increased; at present, the saliva is led out clinically by adopting a mode of enabling a patient to hold a hose, but the drainage effect of the mode on the saliva is poor, the hose is easy to fall off, the pollution or infection of a larger area can be caused, and the use effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a saliva drainage device for trachea cannula to solve the problem that prior art is poor to the drainage effect of patient's oral cavity saliva after trachea cannula operation.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a basic technical scheme is: the utility model provides a saliva drainage device for trachea cannula, includes stock solution bag, drainage hose and miniature liquid pump, the downside of stock solution bag is connected with the fluid-discharge tube, the fluid-discharge tube is connected with the flowing back valve, the drainage hose with the inlet pipe connector of stock solution bag, the drainage hose still with miniature liquid pump is connected, miniature liquid pump is for charging portable suction pump, miniature liquid pump is equipped with control switch, drainage hose fixedly connected with fixed band.

The principle of the basic technical scheme is as follows: the fixed band is fixed whole device, and drainage hose places in patient's oral cavity, starts the saliva of miniature liquid pump with patient's oral cavity in drainage hose drainage to the stock solution bag, and the break-make of flowing back valve control fluid-discharge tube is in order to control the outflow of stock solution bag internal pocket water.

The beneficial effects of the basic technical scheme are as follows: utilize miniature liquid pump to attract the saliva of patient's oral cavity, the effectual of drainage still utilizes the fixed band to bind whole device fixed simultaneously, avoids the unexpected slippage of device, has improved the reliability that the device used.

Preferably, the miniature liquid pump is wrapped with a soft mounting shell outside, and the fixed band is an elastic telescopic band.

Through the setting, the outside cladding of miniature liquid pump has soft installation shell, avoids the accident to collide with miniature liquid pump or the patient in order to bring the unnecessary damage, and the fixed band is elastic expansion band, and it is good to bind fixed effectual, and application scope is wide.

Preferably, the drainage hose with the stock solution bag is for dismantling the connection, the drainage hose cup joints the governing valve.

Through the setting, the regulating valve is used for regulating the speed of the drainage port water, and can also be used for blocking the drainage of the whole device to the port water, so that the liquid storage bag can be conveniently replaced in the drainage process.

Preferably, the drainage hose is sleeved with a drainage tube in a sliding manner, the drainage tube is conical, the liquid inlet end of the drainage tube is larger than the sliding end, and the drainage tube is connected with the drainage hose in an interference fit manner.

Through the arrangement, the conical liquid guide pipe is in sliding interference fit with the drainage hose, the liquid guide pipe slides to the end face of the drainage hose and is placed in the oral cavity of a patient, the liquid inlet end of the liquid guide pipe is larger, and the liquid inlet of the drainage hose is effectively prevented from slipping out of the oral cavity under the action of teeth of the patient; the catheter slides to the outside of the oral cavity of the patient, so that the mouth angle of the patient can be effectively lifted upwards, the possibility of overflow of the saliva from the mouth angle is reduced, and the drainage effect of the whole device on the saliva is further improved.

Preferably, the drainage hose is further fixedly connected with release adhesive paper.

Through the setting, open the rational paper of pasting, bond it in patient's face, further guarantee that the drainage hose can not the slippage and go out patient's oral cavity.
