Abstract
The utility model provides a one-off respiratory tract surface anesthetic injection spray pipe, which belongs to the field of medical treatment technologyand comprises an outside spray pipe, an inside spray pipe, a piston, a medicine injecting opening and a spray head. Four centimeters of the front end of the outside spray pipe is soft and bent into an arc about 120 DEG, and the top part of the outside spray pipe is provided with the spray head on which spray holes is arranged. The piston is arranged in front of the outside spray pipe, and the rear end is provided with the medicine injecting opening. The inside spray pipe is positioned in the outside spray pipe, the length of the injection spray pipe can be changed through the slide of the piston in the outside spray pipe, and a resistance force existing between the piston and the outside spray pipe can ensure that the spray pipe does not slide back by self in the process of medicine injection. When the injection spray pipe is used, the length of the injection spray pipe is adjusted first, then a medical syringe is connected to the medicine injecting opening, the liquid medicine is sprayed from the spray holes in mist shape by pushing the syringe, and the medicine is sprayed to different positions of the respiratory tract. The injection spray pipe has simple structure, the length of the injection spray pipe can be adjusted, the front end is soft and has little injure to the respiratory tract, the one-off use can avoid cross-infection, the fabrication cost is low, the use is easy, and the popularization is convenient.
Description
One, technical field
This utility model is applicable to that medical Clinical Anaesthesiology tracheal intubation forward direction respiratory tract spraying medicine carries out topical anesthesia.Relate to technical field of medical instruments.
Two, background technology
The respiratory tract topical anesthesia is important techniques operation in the clinical anesthesia before the tracheal intubation, the main at present kettle formula aerosol apparatus that uses can only carry out topical anesthesia to oropharynx and glottis zone, can not go deep into spraying in the trachea medicine by glottis, its complex structure, heaviness, operation inconvenience are difficult for disinfecting.
Three, summary of the invention
For overcoming the deficiency of above-mentioned prior art, this utility model provides a kind of disposable respiratory tract topical anesthesia injection spray pipe, this injection spray pipe can not only boil on the nape opposite the mouth, nose, pharynx, cavum laryngis carry out topical anesthesia, and can go deep into that spraying medicine carries out topical anesthesia in the trachea by glottis, can change the length of injection spray pipe easily by the slip of inner nozzle in outer nozzle.
The technical solution of the utility model is:
Disposable respiratory tract topical anesthesia injection spray pipe is made up of outer nozzle, inner nozzle, piston, medicine-pouring port, fog-spray nozzle.The soft crooked circular arc into about 120 degree of 4 centimetres of matter of outer nozzle front end, the top has on fog-spray nozzle, the fog-spray nozzle and has spray holes.The inner nozzle front end has piston, and the rear end is a medicine-pouring port.Inner nozzle is positioned at outer nozzle, can change the length of injection spray pipe by the slip of piston in outer nozzle, and inner nozzle does not slide backward voluntarily when having certain resistance to guarantee injection between piston and outer nozzle.Regulate the length of injection spray pipe during use earlier according to the needs of different patient's different parts, again medical notes are thanked to device and connect medicine-pouring port, directly the pushing syringe medicinal liquid nebulizes from the spray holes ejection, to respiratory tract different parts spraying medicine, carries out the respiratory tract topical anesthesia as required.
The disposable respiratory tract topical anesthesia injection spray pipe of making according to technique scheme, simple in structure, be convenient to manufacture, front end is soft little to respiratory tract injury, can satisfy the needs of different patients, different parts by the length that changes injection spray pipe, cross infection is avoided in disposable use, and is cheap, easy to use, be convenient to promote.
