Description

a sputum suction device

technical field

The utility model relates to the field of medical equipment, in particular to a sputum suction device.

Background technique

Sputum suction is a common nursing practice that removes secretions from a patient's airway to keep their airway open. Sputum culture refers to sucking out the patient's deep sputum and putting it into a sterile sealed bottle. According to the needs of the disease, aerobic bacteria culture, anaerobic bacteria culture, Mycobacterium tuberculosis culture or fungal culture are carried out. It is often used for the etiological diagnosis of respiratory tract infections. In clinical practice, an electric sputum suction device is often used to connect the sputum suction tube/sputum culture tube to suck out the deep sputum of the patient in the form of negative pressure. However, there are many problems in clinical bedside suctioning:

Negative pressure adjustment problem: The commonly used clinical negative pressure suction device requires nurses to adjust the suction negative pressure by themselves. However, manual adjustment often leads to too large or too small suction negative pressure. If the negative pressure is too small, the sputum specimen collection fails.

When sputum blocks the suction tube, due to the continuous operation of the negative pressure machine, if the sputum suddenly stops blocking, the suction negative pressure will suddenly increase, which will lead to injury to patients, especially infants and young children with weak tissue structure.

Since the suction tube and the negative pressure machine are in a communication structure, the sputum may be sucked into the negative pressure machine, which affects the operation of the negative pressure machine and is not easy to clean.

The same sputum suction device can only be connected to one type of sputum suction tube. For premature infants with small nasal cavity, it is often impossible to insert it. However, clinical nurses use oral suction instead, which often results in more saliva mixed in specimen collection. Ordinary sputum culture tubes have no scale, and the depth of insertion is difficult to control, which often leads to excessive mucosal damage or gag reflex in children. Partial colonization of bacteria cannot reflect the actual flora of children with pulmonary infection.

The patent with publication number CN215690318U discloses a sputum suction device that can adjust negative pressure, but it does not solve the problem that when sputum blocks the sputum suction tube, due to the continuous operation of the negative pressure machine, if the sputum suddenly stops blocking, it will cause sputum suction. The problem of sudden increase in negative pressure.

Therefore, a first power supply module and a first switch control module are provided. When the pressure sensor 5 detects that the negative pressure exceeds the threshold, the first switch control module controls the first power supply module. The power outage causes the negative pressure machine to suspend work. The above threshold can be set according to the usage. For example, when used by premature infants, the threshold is set to 85mmHg; when used by full-term infants, the threshold is set to 105mmHg. The above thresholds are only the preferred solutions of this application and do not limit the size or range of the thresholds. .

In the specific implementation process, both the power line interface and the USB interface can be connected to the battery. Since there may be a power outage in real life, a battery with a power storage function is provided, and the charging interface can be the USB interface 7. When the power is out and the battery is dead, an external charging device can be used to charge the sputum suction device.

In this embodiment, the first interface includes an interface a and an interface b; the first interface is arranged on the side of the liquid collection bottle 2 .

In the specific implementation process, the first interface can be set as a combination of multiple interfaces, and can be connected to various types of sputum suction tubes, such as a pediatric sputum suction device.
