Description

A closed sputum suction device

technical field

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

Background technique

The closed sputum suction tube is a new type of sputum suction device. Compared with the traditional open sputum suction tube, it can reduce the fear of patients while ensuring effective ventilation, avoid pollution and cross infection, and reduce the workload of medical staff. Workload and occupational exposure. Therefore, it has been widely used clinically.

Wherein, in the use of the closed sputum suction tube, after the sputum suction is completed, the sputum suction tube must be flushed to ensure the cleaning of the sputum suction tube. For this flushing operation, the requirements are very strict, especially the sequence of the steps. The standard flushing method is as follows:

(1) Keep the negative pressure connector connected to the negative pressure connector, first press the negative pressure control valve to provide negative pressure, and then put in the flushing fluid for flushing;

(2) After flushing, stop putting in the flushing liquid first, and then relax the negative pressure control valve to close the negative pressure after the flushing liquid in the sputum suction tube is fully sucked.

For the above flushing methods, medical personnel need to carry out special learning and training, especially to master the sequence of turning off the negative pressure on the switch and putting in the flushing fluid. The patient's airway, causing serious consequences.

Although the vast majority of medical staff have undergone professional training, it is difficult to ensure that operational errors will never occur in the highly stressful and busy clinical work. Therefore, it is necessary to further improve the safety of the closed sputum suction tube in use.

Utility model content

In order to solve the safety problem of the above-mentioned closed sputum suction tube during flushing, the utility model provides a closed sputum suction device that can manually control the switch of the flushing fluid and is safer in use.

The utility model provides a closed sputum suction device, which comprises a sputum suction tube, a breathing joint and a negative pressure joint respectively connected to both ends of the sputum suction tube; the negative pressure joint is composed of a connecting pipe and a negative pressure control valve. Composition; the breathing joint is composed of a three-way pipe and a joint; the three-way pipe is composed of a main pipe and a branch pipe, one end of the main pipe is connected with the sputum suction pipe, the other end is an empty end, and one end of the branch pipe is provided There are joints; on the side wall of the main pipe, there is a humidification port connected with the dosing component and a flushing port connected with the flushing component; the flushing component includes a flushing liquid container, a flushing liquid conduit and a flushing liquid Manual squeeze switch on catheter.

Further preferably, the manual squeeze switch is a squeeze valve.

Further preferably, the tee is a T-shaped tee.

Further preferably, both the humidification port and the flushing port are located on opposite sides of the branch pipe.

Further preferably, it also includes a protective film covering the sputum suction tube. Compared with the existing closed sputum suction tube, the sputum suction device of the present utility model has the following significant advantages:

(1) You only need to keep pressing the negative pressure control valve to maintain negative pressure, and control the opening and closing of the flushing liquid by manually squeezing the switch. It is not easy to reverse the operation steps, and you will not forget to turn off the flushing liquid, which improves the safety of the sputum suction device. Effectively prevent the occurrence of medical accidents;

(2) When putting in or stopping the flushing liquid, it is not necessary to connect the flushing liquid conduit to the flushing port repeatedly, thereby reducing the possibility of contamination of the sputum suction device and reducing the workload;

(3) The operation method is simpler and easier for medical staff and even non-medical staff to master.

The utility model is described in further detail below through the specific embodiment, but not limitation of the utility model, according to the above-mentioned contents of the utility model, according to common technical knowledge and conventional means in this field, without departing from the above-mentioned basic technology of the utility model Under the premise of thinking, other various forms of modification, replacement or change can also be made.

Detailed ways

Example 1

The closed sputum suction device shown in Fig. 1 includes a sputum suction tube 1, and a breathing joint and a negative pressure joint respectively connected to both ends of the sputum suction tube 1. Wherein, the negative pressure joint is composed of a connecting pipe 31 and a negative pressure control valve 32 ; the breathing joint is composed of a three-way pipe 21 and a joint 22 .

The three-way pipe 21 is T-shaped and consists of a main pipe and a branch pipe. One end of the main pipe is connected with the sputum suction pipe 1 , and the other end is an empty end 23 . One end of the branch pipe is provided with a joint 22; on the side wall of the main pipe, a humidification port connected to the dosing assembly 4 and a flushing port connected to the flushing assembly are provided, and the humidification port and the flushing port are located on the opposite side of the branch pipe. side, the functions do not interfere with each other.

The flushing assembly includes a flushing liquid container 51, a flushing liquid conduit 52 and a manual squeeze switch 53 for controlling the flushing switch.

When using the closed sputum suction device of the present utility model, the empty end 23 of the supervisor is connected to the patient's artificial airway respectively, the joint 22 is connected to the ventilator or the artificial nose, the connecting pipe 31 is connected to the negative pressure suction device, and Sterile physiological saline is prepared in the rinse solution container 51 .

When cleaning the sputum suction device, you only need to keep pressing the negative pressure control valve 32 to maintain the negative pressure, and you can control the opening and closing of the flushing liquid at any time by manually squeezing the switch 53 to clean the device, which can effectively avoid misoperation by medical staff and negligence, improve the safety of the product.

As a preference of the present utility model, the device preferably squeezes the valve as the manual squeeze switch 53, which is convenient to use; it also includes a film protective cover 6 wrapping the sputum suction tube 1, which can prolong the service life of the sputum suction device.
