Description

A manual suction device for oral secretions

technical field

The utility model relates to a simple suction device, in particular to a manual suction device for oral secretions.

Background technique

At present, in the intensive care unit, when patients undergo mechanical ventilation through orotracheal intubation, oral secretions often increase. If the patient’s oral secretions are not cleaned up in time, they may overflow from the mouth, resulting in saliva-related dermatitis and contamination of the internal jugular vein catheter. And the contamination of bed sheets, which may lead to ventilator-associated pneumonia in severe cases. For critically ill patients, related infections will not only increase medical expenses, increase the burden on patients, but also increase the mortality rate. In order to solve the above problems, the prior art uses a disposable sputum suction tube to extend into the patient's mouth, and directly contacts with the oral skin to absorb the patient's oral secretions. However, frequent use of the sputum suction tube to attract oral secretions will increase the impact on the patient's mouth The stimulation of the mouth produces more oral secretions, and the direct contact of the suction tube with the oral mucosa will also cause damage to the oral mucosa. Patients tend to be agitated and uncooperative during sputum suction nursing, which has an indirect negative impact on the condition. For medical staff, the operation procedure of sputum suction is cumbersome, and frequent sputum suction is time-consuming and labor-intensive. Therefore, the industry urgently needs to design a manual suction device for oral secretions, which can conveniently attract the secretions in the patient's oral cavity, and will not stimulate the oral cavity during the suction process.

In the aforementioned manual suction device for oral secretions, the tank body is made of transparent material.

Compared with the prior art, the utility model has the following beneficial effects:

1. The utility model includes a sealed collection tank, the connection port A of the sealed collection tank is connected with a suction tube, and the suction tube extends into the patient's oral cavity, aiming at the secretions of the patient's oral cavity, and the connection port B of the sealed collection tank is connected with a device There is a negative pressure tube, and the other end of the negative pressure tube is connected to a negative pressure suction device. Through the suction of the negative pressure suction device, the utility model can effectively suck the secretions in the patient's cavity. In addition, the utility model has a simple structure , easy to carry and easy to use.

2. The side of the tank cover of the utility model is provided with stripes, which is beneficial for the medical staff to unscrew the tank cover and facilitate cleaning of the secretions in the tank.

3. The length of the suction tube of the present invention is 16-20cm, and the length of the suction tube that can be put into the patient's oral cavity is 15cm. This length is the length from the incisors to the throat, which can ensure that the suction tube does not enter the patient's airway.

4. The end of the suction tube of the present utility model is covered with an arc-shaped body, which avoids direct contact between the end of the suction tube and the oral mucosa to cause irritation, and does not damage the oral mucosa when sucking oral secretions.

Detailed ways

A manual suction device for oral secretions, the composition is shown in Figure 1-3, it includes a sealed collection tank 1, the sealed collection tank 1 includes a tank cover 2 and a tank body 3 connected by threads, as shown in Figure 2, the Said tank cover 2 is provided with connection port A4 and connection port B5, connection port A4 is connected with a suction tube 6, the suction tube 6 can use a sputum suction tube, and the suction tube 6 stretches into the sealed collection tank 1, and is connected with the tank body 3 The bottom of the tank is in contact with the bottom of the tank; the connection port B5 is connected with a negative pressure tube 7, and the other end of the negative pressure tube 7 is connected with a negative pressure suction device 8. For easy portability, the negative pressure suction device 8 usually uses a syringe; as shown in Figure 3 , a three-way valve 9 is connected in series in the middle of the negative pressure pipe 7, and a ventilation tube 12 is connected to the three-way valve 9, and the switch on the three-way valve is adjusted. When the syringe is connected with the ventilation tube 12, the syringe is released When the syringe is in communication with the sealed collection tank 1, the syringe sucks air, and the air in the sealed collection tank 1 is absorbed to generate negative pressure, thereby attracting the secretions in the patient's oral cavity into the sealed collection tank 1, through the three-way valve Cooperating with the syringe, it can achieve multiple consecutive suctions of the patient's secretions. The side of the tank cover 2 is provided with stripes 10, which is beneficial for the medical personnel to unscrew the tank cover 2 and clean the secretions in the tank body 3 conveniently. The end of the suction tube 6 is sleeved with an arc-shaped body 11 .
