Description
Technical field
The disclosure belongs to technical field of medical equipment, and in particular to a kind of self set-up type intelligence expectoration auxiliary device and side
Method.
Background technique
Sputum is mainly as secreted by the body of gland and goblet cell of trachea-bronchial epithelial cell.When acute inflammation occurs for respiratory tract
When disease, serous gland secretion increases, and forms more and dilute sputums.When inflammation later period or chronic inflammation, goblet cell muccus gland
Secretion increase, sputum then becomes sticky, in respiratory tract formed product phlegm.Existing expectoration auxiliary product has following several:
One, expectorant, expectorant mainly pass through dilution sputum or liquefaction mucus, make it easy to expectoration, commonly use eliminating the phlegm
Medicine can be divided into mucolytic class and irritation eliminating the phlegm class.Mucolytic class expectorant is dropped by adhesive component in destruction sputum
The viscosity of low sputum, sticky sputum can be dissolved as the sputum of flowing by he, to be easy to expectoration.Stimulant expectorant is
By stimulation bronchial mucosa or gastric mucosa, reflexive promotion bronchial secretion, to achieve the effect that dilute sputum.It uses
Drug eliminating the phlegm will affect the normal function of other organs such as stomach, cause the adverse reactions such as the allergy of user, to health
Bring hidden danger.Such drug negative interaction is obvious, and the discomfort used largely influences the quality of life of patient.
Two, hand-held knocking rock sputum ejection machine, patient takes prostrate, lies on one's side or seat when treatment, can effectively clear breathing
Road secretion reduces lung's moist rales, improves patient's arterial oxygen saturation, promotes inflammatory resolution, prevents the hair of pulmonary infection
Its is given birth to and controls further to develop.Its working strength is lower than artificial clap significantly and carries on the back expectoration.But equipment volume is big, main screw lift weight,
Cannot achieve portable, and buying expenses are high, also have higher requirements to operator, and every time can only one position of knocking, cannot
Simultaneously to full thorax knocking.Whole operation process needs patient body position to cooperate, and presently mainly uses in related department of hospital, one
As need according to patient profiles by health care professional's periodic operation, promoting in the home for the aged and family has larger difficulty, and portion
Divide patient that can not adapt to this impression of knocking, it is not easy-tolerated.
Three, sputum aspirator mainly attracts the main components such as component, reservoir to form, work by controller, pump, shell, inner cavity
Make principle are as follows: pump is controlled by controller and generates vacuum suction source, trouble is connected to by breathing pipeline and corresponding ancillary equipment
The throat of person is intracavitary, and the intracavitary phlegm of patient, fester etc. are sucked out and are collected into the reservoir of equipment formulation, to keep respiratory tract
It is unobstructed, prevent aspiration pneumonia, atelectasis, a kind of method of the complication such as asphyxia.Indication is especially more in coma patient, sputum
There is possible situation of suffocating, need intrarterial, inject contrast agent or dilutes the patient of sputum.When operation medical staff need by
A piece sputum aspirator tube is inserted into neural throat, is turned on the switch, and sputum is drawn.It will lead to the adverse reactions such as patient's retch when suction sputum, if
Improper use will lead to patients with respiratory tract damage, and by hardship, the discomfort just because of product causes to suffer from security risk
The influence that the body and psychology of person is subjected to, greatly affects the quality of life of patient.
By assisting product analysis discovery to existing expectoration in the market, there are still the followings for product on the market at present
Defect:
One, there are security risks, while assisting expectoration, injury of the patient by different degrees of body and mind；
Two, comfort and convenience are poor, assist the process efficiency of expectoration low, and body-sensing is poor when patient uses；
Three, it needs medical staff to assist, can not promote the use of in the family, relevance factor is low.
