Sputum collecting device

Abstract

The invention relates to the technical field of medical instruments, in particular to a sputum collection device which comprises a case, a negative pressure air suction mechanism is arranged in the case and communicated with a liquid storage bottle, the liquid storage bottle is communicated with one end of a transition pipe, the other end of the transition pipe is communicated with a sputum suction pipe, and a diaphragm cover is arranged on the sputum suction pipe; a self-heating module is arranged on the pipe wall of the sputum suction pipe, and a scratching head capable of expanding and shrinking is arranged at the head end of the sputum suction pipe; the tube wall of the sputum suction tube is further provided with a hollow air channel, and the front end of the sputum suction tube is communicated with a curettage head. The transition tube is communicated with the sputum suction tube through a middle rotating head; the instant suction force is large, the sputum suction tube can be at the temperature making the respiratory tract of the human body comfortable, the discomfort of a patient is relieved, and the situation that internal matter flows unsmoothly due to the fact that the tube is too cold is also prevented; the head end of the pipeline generates stimulation to promote the patient to perform effective cough action and stir away sputum; the diaphragm cover can prevent sputum or other foreign matters in the body of the patient from splashing out, so that the health of an operator of the device is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a sputum collection device. Background technique

[0002] The respiratory tract is the passage through which the air flows when the lungs breathe. It supports the normal physiological metabolism of the human being. In medicine, the nose, pharynx and larynx are collectively referred to as the upper respiratory tract. , pus, etc. can block the airway, causing the patient to experience dangerous symptoms such as difficulty breathing.

[0003] As an important nursing equipment, the sputum suction device is suitable for patients who have difficulty in spontaneously expelling sputum due to illness, coma, surgery, etc. It can effectively clean the respiratory tract. If there is too much sputum, it can be used to help improve. If some vomit is accidentally entered, it can also be sucked out by the negative pressure of the sputum suction device, which can avoid the obstruction of...
