Description

Closed suction device

Technical Field

The utility model belongs to the technical field of sputum suction devices, and in particular relates to a closed sputum suction device.

Background technique

Closed suction does not require disconnecting or stopping mechanical ventilation. The suction tube is covered with a transparent film. The entire suction process is completed in a closed environment. The operator does not need to wear sterile gloves to complete the operation. When the patient is seriously ill and unable to cough up sputum, sputum blockage in the trachea can easily pose a life-threatening danger, so a closed suction device is needed.

The existing closed suction device can only suck out the secretions in the airway, and the secretions in the mouth still need to be sucked out using an open suction tube. There are still certain limitations, which not only increases the operation time and cost, but also may increase the risk of cross infection.

Utility Model Content

The purpose of the utility model is to provide a closed sputum suction device, which can suck secretions in the oral cavity, avoid the use of an open sputum suction tube, reduce operation time and cost, reduce the risk of cross infection, and improve the use effect of the equipment.

The technical solutions adopted in this utility are as follows:

A closed sputum suction device comprises a transparent tee, an airway interface is arranged at the top of the transparent tee, an airway cannula is arranged above the airway interface, a first connector which is sealed and screwed with the airway interface is fixed through the bottom end of the airway cannula, an adjustment ring is sleeved on the outer wall of the airway cannula, a plurality of rubber sliding rings which slide damped with the airway cannula are arranged on the inner wall of the adjustment ring, an annular groove is provided inside the adjustment ring, a plurality of suction holes which are connected with the annular groove are provided on the outer wall of the adjustment ring, a telescopic tube which is connected with the annular groove is provided on one side of the bottom end of the adjustment ring, and the other end of the telescopic tube is connected with the first connector.

Furthermore, the outer walls of the airway cannula and the telescopic tube are both provided with a first valve.

Furthermore, a mouth mask is provided at the bottom of the adjustment ring, and straps are provided on both sides of the mouth mask.

Furthermore, a suction interface is provided at the bottom end of the transparent tee, a suction tube is screwed inside the suction interface, a duckbill valve is provided at the other end of the suction tube, and a negative pressure device interface is provided on the other side of the duckbill valve.

Furthermore, a ventilator connection port is provided at the side end of the transparent tee.

The technical effects achieved by this utility model are:

The practical closed sputum suction device is provided with an adjustment ring which, together with a rubber sliding ring, can be fixed at any position on the airway tube, thereby improving the flexibility of the device. An external negative pressure suction device is used to generate negative pressure in the annular groove, which is convenient for sucking secretions in the oral cavity and avoids the use of an open sputum suction tube, thereby reducing operation time and cost, reducing the risk of cross infection, and improving the use effect of the device.

As shown in Figures 1-3, the closed sputum suction device includes a transparent tee 1, an airway interface 2 is arranged on the top of the transparent tee 1, an airway cannula 4 is arranged above the airway interface 2, a first connector 3 which is sealed and screwed with the airway interface 2 is fixed on the bottom end of the airway cannula 4, an adjusting ring 5 is sleeved on the outer wall of the airway cannula 4, and a plurality of rubber sliding rings 8 which slide with the airway cannula 4 for damping, the adjusting ring 5 can be fixed at any position of the airway cannula 4 according to needs, which is more practical, an annular groove 6 is provided inside the adjusting ring 5, and a plurality of suction holes 7 which are connected with the annular groove 6 are provided on the outer wall of the adjusting ring 5, which is convenient for sucking oral secretions, a telescopic tube 9 which is connected with the annular groove 6 is provided on one side of the bottom end of the adjusting ring 5, and the other end of the telescopic tube 9 is connected with the first connector 3, which has a simple structure and is easy to operate, and can be conveniently adjusted. The suction of oral secretions of patients avoids the trouble of suction with an open suction tube. When in use, the adjusting ring 5 can be inserted into the oral cavity of the patient. When the external negative pressure suction device is started, the secretions in the oral cavity are sucked into the annular groove 6 through the suction hole 7, and then enter the telescopic tube 9 from the annular groove 6, and then enter the suction tube 14 connected to the transparent three-way 1. It is more complete and practical; the outer walls of the airway cannula 4 and the telescopic tube 9 are both provided with a first valve 10, which is convenient for independent control of the airway cannula 4 and the telescopic tube 9, and is convenient for suction of tracheal or oral secretions according to the needs of the patient, which is more complete; the bottom of the adjusting ring 5 is provided with a mouth mask 11, and both sides of the mouth mask 11 are provided with straps, which are convenient for further fixing the airway cannula 4, making the use of the equipment more stable, and can also prevent the overflow of secretions in the patient's mouth, which is more practical.

As shown in Figure 1-2, the bottom end of the transparent tee 1 is provided with a sputum suction interface 13, the interior of the sputum suction interface 13 is screwed with a sputum suction tube 14, the outer wall of the sputum suction tube 14 is provided with a protective film, the outer wall of the sputum suction tube 14 is provided with a protective film, the protective film can play a sealing role to prevent the sputum suction tube 14 from splashing sputum during sputum suction, can reduce the possibility of medical staff contacting with patient body fluids, and reduce cross infection, the other end of the sputum suction tube 14 is provided with a duckbill valve 15, the other side of the duckbill valve 15 is provided with a negative pressure device interface 16, the negative pressure device interface 16 is convenient for connection with an external negative pressure suction device, and is convenient for normal use of the equipment; the side end of the transparent tee 1 is provided with a ventilator connection port 12, which is convenient for connection with an external ventilator. When suctioning sputum, the ventilator can be disconnected uninterruptedly, and hypoxia of the patient is avoided when suctioning sputum; an airway humidification joint is provided through one side of the transparent tee 1, which is convenient for injecting humidifying liquid through the airway humidification joint to avoid the viscosity of sputum and enable the equipment to be used normally.
