Technical Field
The invention belongs to the technical field of medical instruments, and relates to a medicine sprayer for a department of respiration
Background
Respiratory medicine is a department in modern western medicine. Common conditions are pneumococcal pneumonia, acute lung abscess, pneumococcal pneumonia, asthma, staphylococcus aureus pneumonia, pulmonary aspergillosis, pulmonary candidiasis, pulmonary alveolar proteinosis, herpangina, viral pneumonia, silicosis, pulmonary actinomycosis, simple pulmonary eosinophil infiltration, asthmatic pulmonary eosinophil infiltration, obstructive emphysema, bronchiectasis, desquamation interstitial pneumonia, immunodeficiency pneumonia, idiopathic obstructive bronchiolitis complicated with pneumonia, and respiratory bronchiole related interstitial lung disease.
The sore throat or the tonsil inflammation is a common disease in respiratory tract internal medicine, when medical staff treat patients with upper respiratory tract infection, the treatment efficiency is low by adopting treatment methods such as intravenous injection or medicine taking, and the better treatment method is to directly spray medicine on the diseased part. The method generally adopted at present is to spray medicine on the affected part after sucking the medicine liquid by a syringe without a needle head, when the treatment method is used, although the treatment method is very simple, the medicine liquid sprayed by the syringe is in a bundle of water column pattern and can not be uniformly distributed on the affected part, and medical staff can hardly control the medicine spraying amount and waste a part of the medicine liquid; moreover, because the oral cavity space of a human body is small, the administration position is not easy to find, if the liquid medicine is carelessly sprayed into the respiratory tract and the digestive tract, the respiratory tract spasm can be caused, and even the life safety of a patient is endangered in serious cases; in addition, because the oral cavity and the nasal cavity are connected with the respiratory tract inlet and the digestive tract inlet, the traditional operation method is very easy to cause respiratory tract spasm when liquid medicine enters the respiratory tract and the digestive tract, even endangers the life safety of patients in serious cases, and brings great working difficulty to medical staff.
Therefore, the utility model with application number 201521004070.0 discloses a medicine sprayer for respiratory medicine, which comprises a spray head, a medicine conveying pipe, a medicine storage box and a pressure bag which are connected in sequence, wherein the spray head is of a T-shaped structure and comprises a vertical pipe and a horizontal pipe, a pipe body of the horizontal pipe is communicated with the upper end of the vertical pipe, nozzles are respectively arranged at two ends of the horizontal pipe, a lighting lamp is arranged at the top of the horizontal pipe, and the lower end of the vertical pipe is communicated with the upper end of the medicine conveying pipe through a corrugated pipe; two arc expansion plates are oppositely arranged on two sides of the medicine conveying pipe, and a push-pull ring is movably sleeved on the pipe body of the medicine conveying pipe; a one-way valve is arranged in the medicine storage box, a first connecting pipe and a second connecting pipe are arranged on a pipe body of the medicine storage box, the first connecting pipe and the second connecting pipe are both positioned above the one-way valve, and the pipe diameter of the first connecting pipe is larger than that of the second connecting pipe; a finger board is arranged at the joint of the air pressure bag and the medicine storage box. The utility model discloses can avoid directly blowing into the respiratory track that the respiratory track caused amazing, the phenomenon of spasm has reduced medical staff's the work degree of difficulty.
In the medicine sprayer, the whole spray head is in a T-shaped structure, and the spray head is easy to damage the oral cavity in the oral cavity after being arranged in the T-shaped structure because the space of the oral cavity of a human body is narrow; in addition, because this nozzle setting is in the left and right sides of T type structure, therefore when using, this nozzle can' T directly spray liquid medicine to the assigned position to cause the medicine spraying effect of medicine spraying device relatively poor. In addition, when spraying medicine, the liquid medicine that the nozzle spun is usually by the mixed of multiple medicament, usually through the medicament transport realize mixing in the pipeline among the prior art, but the efficiency of mixing like this is lower, can't realize the intensive mixing of medicament, finally causes the effect of medicine spraying device not obvious enough.
