Description

Drainage cup used after off-line of mechanical ventilation patient

Technical Field

The utility model relates to a machinery field of ventilating, more specifically say, relate to a mechanical ventilation patient off-line back uses drainage cup.

Background

In order to rescue the life of a patient, keep the airway unobstructed and establish a mechanical ventilation channel, an artificial airway (trachea cannula and tracheotomy) is usually required to be established, a respirator is used for tracheotomy to treat respiratory failure caused by various reasons, the method is a common method for rescuing critical patients in recent years, particularly an ICU (intensive care unit), the patient using the respirator for a long time is treated, and tracheotomy not only ensures that the patient uses the respirator, but also has the double functions of sucking phlegm, keeping the respiratory tract unobstructed and controlling respiratory tract infection.

Referring to fig. 7, after the tracheotomy patient is separated from the ventilator, the upper respiratory tract completely loses the heating, humidifying and filtering functions of the gas, and the defense function is weakened, so that the nursing staff is required to humidify the artificial airway of the patient, and the general method comprises the following steps: 1. a Venturi mask is sleeved at the tracheostomy opening (20) of the tracheostomy cannula (10) of the patient for oxygen inhalation; 2. an artificial nose is sleeved on the air incision (20) of the patient for oxygen inhalation; 3. the humidification is continuously pumped into the tracheostoma (20) of the patient by a micro pump; 4, an oxygen source is connected with a threaded pipe (50) of a common respirator of the ICU, enters from an oxygen inlet (60) and is heated by a humidifying bottle (40) to heat and humidify the artificial airway of the patient, and condensed water in the pipeline is contained and connected by a water receiving cup (30) in the period.

When the last method is adopted, cough and sputum of a tracheotomy patient need to be drained from the sputum of the patient at the air outlet (a) of the patient, and in the prior work, the sterile and atmosphere-communicated transparent plastic bag (80) is wrapped at the air outlet (a) of the patient generally, and the sputum is clamped by the clamp (70) for drainage, however, the sputum is wrapped by the transparent plastic bag (80), and after the hot gas is exhaled, the accumulated water is easy to deform, the air outlet (a) of the patient is blocked, when the sputum of the patient is coughed out, the sputum is easy to silt, therefore, nurses need to observe frequently and change in time, the workload is increased, and the production of waste plastic bags is increased.
