Description

The gas formula expectoration instrument that shakes

Technical field

The invention belongs to technical field of medical instruments, be specifically related to a kind of gas formula expectoration instrument that shakes, be applicable to the clinical or home care of medical institutions, help patient's expectoration

Background technology

Along with industrial expansion causes the aggravation of environmental pollution and the quickening of aged tendency of population process, the pulmonary disease patient is ascendant trend year by year, the since two thousand one global patient who dies from chronic obstructive pulmonary disease every year reaches more than 3,000,000, becomes the global the third-largest cause of the death.In the ill process of chronic obstructive pulmonary disease, the patient shows as cough, expectoration, breathe hard and/or pant and increase the weight of, amount of expectoration increases, and be purulence or glutinous purulence, even follow inflammation such as heating, many often unable expectorations of the particularly old and weak patient of patient, sputum to be difficult for discharging and cause other complication, if untimely effective disposal then can lead to grave consequences.

As the industry's knowledge of the reason, it is the extremely important measure of treatment chronic obstructive pulmonary disease that the control breathing road infects, and effectively expectoration is the key of control infection.At present, mainly contain following three kinds in the clinical disposal options of medical treatment to expectoration difficulty patient: the one, employing has easypro (expansion) and opens medicine of bronchus effect such as the medicine of gentamycin and dexamethasone and so on; The 2nd, adopt the negative-pressure type sputum aspirator; The 3rd, patient's chest and back is kowtowed the physiotherapy of bat.

Can only implement down in medical institutions such as hospital and the leading of medical personnel for preceding two kinds in above-mentioned three kinds of disposal options, and and be not suitable for family, though the third disposal options can be helped to implement by patient's entourage such as family members, but, nursing intensity as treatment personnel's family members and/or medical personnel is big, kowtow and clap the position and be difficult to hold and kowtow face be restricted, and kowtow bat dynamics and skill be difficult to medical meaning on the expectoration effect adapt.

Be no lack of the technical scheme that is seen in sputum elimination machine in disclosed Chinese patent literature, publication number CN1330915A has recommended a kind of sputum evacuator for respiratory function recovery, utilizes negative pressure mode to inhale expectorant; The recovery apparatus for vibration evacuation of sputum that CN1330961A provides acts on same CN1330915A; A kind of air blowing sputum ejector that utility model Granted publication CN2629683Y discloses is with the mode of vibration help patient expectoration of vibrating ball; The effect and the CN2629683Y of the portable vibrations sputum ejector of free position that CN201168307Y discloses are similar; The public all sputum ejectors of CN201329062Y utilize gas to make the vibrating ball vibration, help patient's expectoration, or the like.

Though the disclosed technical scheme of above-mentioned patent documentation has the terse strong point that is suitable for family's use of structure, exists and uses trouble, to patient's shortcomings such as thoracic dorsal application point position limitation.

The controlled vibrated sputum elimination device in a kind of intelligent full thoracic cavity of typical expectoration device such as Granted publication CN201727690U instruction, this scheme is essentially a kind of expectoration vest, 42 vibration units are set on this expectoration vest, after the patient puts on this expectoration vest, can alleviate entourage's the intensity of accompanying and attending to, because need not artificially to kowtow bat to the patient by the entourage, but there are shortcoming in complex structure and ruggedness, safety.The domestic sputum ejector that CN2502691Y releases utilizes the vibration principle of speaker to help patient's expectoration.And the intelligent full thoracic cavity higher-order of oscillation sputum elimination machine of CN201356827Y proposition, Instructions Page 3 the 21st with this patent walks to 5 technique effects that page 4 the 2nd row is concluded, yet the concrete structure of the unexposed air vibrating machine of this patent, and the air vibrating machine is the agent structure of higher-order of oscillation sputum elimination machine.Sputum elimination machine should have an air chamber, and the air that is incorporated in the air chamber by the external world vibrates in air chamber, makes the expectoration vest or the vibration of expectoration pectoral girdle that are connected with air chamber by pipeline (breather), expectoration difficulty person is played kowtow the bat massage effect, helps expectoration.

Yet, the whether reasonable of air chamber structure all can produce certain influence to the power configuration of air inducing mechanism and the action effect of tympanum dish, because gas chamber volume is excessive, easily cause air inducing mechanism power to increase and waste energy, and gas chamber volume is too small, then can produce the tympanum dish actuating mechanism that drives the action of tympanum dish and interfere.Therefore, how find between tympanum dish actuating mechanism interfered rational equilibrium point to become industry to pay close attention to and the technical problem of expectation solution with avoiding causing because of the cavity volume of air chamber is too small at the power consumption of saving air inducing mechanism, to this, the applicant has carried out positive exploration, find a way to resolve the problem, technical scheme described below produces under this background
