Description
Technical Field
The application relates to the technical field of medical instruments, in particular to a tracheal cap for preventing splashing of a tracheal cannula.
Background
Tracheotomy is a common surgical operation, can quickly relieve respiratory tract obstruction, is convenient for timely cleaning respiratory tract secretion, increases effective ventilation, improves the success rate of rescue, and is widely used in clinic.
However, in tracheotomized patients, the incision is exposed and the cannula opening is unobstructed, which is a condition in which sputum spray often occurs when the patient coughs vigorously. The spittle which is splashed not only pollutes sick beds, walls and adjacent patients, but also often pollutes medical care personnel at night when performing treatment and nursing, thus bringing inconvenience to the treatment and nursing work and being easy to cause cross infection.
In the related technology, a hose with one closed end and an open end with an elastic function at the other end is used as a sleeve for preventing splashing, the hose structure enables the sleeve to have elasticity and can be extended when a tube core is pulled out, the open end needs to be larger than the maximum diameter of the tube core when being loosened to the maximum size, and the open end can be tightly sleeved on a tube opening of a medical tracheal cannula after being locked. It can separate the sputum and blood splashed from the medical tracheal cannula, and avoid the pollution to the medical staff.
However, since the sleeve is closed after being sleeved on the tracheal tube and cannot stretch out after being pulled out along with the tube core, if the patient coughs again, the pressure in the tracheal tube increases, the sleeve is separated from the tracheal tube under the impact of air pressure, and the sputum is splashed again.
Disclosure of Invention
The embodiment of the application provides a tracheal cap for tracheal cannula prevents splash to because the sleeve pipe box is sealed after on tracheal cannula in solving the correlation technique, and the sleeve pipe can't extend again after extracting along with the tube core, coughs once more if the patient, and the intraductal pressure of tracheal cannula can increase, can lead to the sleeve pipe to break away from tracheal cannula under the impact of atmospheric pressure, leads to the problem of sputum splash once more.
In a first aspect, there is provided a tracheal cap for tracheal cannula splash prevention comprising:
one end of the elastic opening is sleeved on the sleeve opening of the tracheal sleeve;

Preferably, the inner wall of the guide pipe 4 is trumpet-shaped, and the diameter of the guide pipe 4 is gradually reduced from one end close to the telescopic pipe 2 to one end far away from the telescopic pipe 2.
When the patient coughs acutely, the sputum splashes from the large-diameter end to the small-diameter end of the drainage tube 4 along with the inner wall of the drainage tube 4 and cannot flow back to the large-diameter end from the small-diameter end.
Furthermore, the tracheal cap also comprises a reversing tube 5, one end of the reversing tube 5 is connected with one end of the draft tube 4 far away from the telescopic tube 2, and the axis of the reversing tube 5 is not in the same straight line with the axis of the draft tube 4.
The reversing tube 5 is bent to guide the sputum sprayed from the flow guiding tube 4 to a designated position, so as to prevent the sputum from being directly sprayed to the body of medical staff and the bed sheet and quilt cover.
Furthermore, an included angle between the axis of the reversing pipe 5 and the axis of the draft tube 4 is an obtuse angle.
When using the trachea cap, honeycomb duct 4 is in vertical state basically, and switching-over pipe 5 is crooked upwards, changes the splash direction of sputum to play certain resistance to the sputum, reduce the splash power of sputum.
Furthermore, the angle between the axis of the reversing tube 5 and the axis of the flow guide tube 4 is 105 °.
When the contained angle between the axis of switching-over pipe 5 and the axis of honeycomb duct 4 was 105, can play the biggest effect that falls and hinder, most sputum can accumulate in switching-over pipe 5, can not flow backwards to honeycomb duct 4 in, and the state that the less part sputum can be with little drippage is similar drips to the assigned position, prevents to pollute the sick bed.
