Description
[technical field]
This utility model relates to a kind of sputum aspirator, and specifically this utility model relates to a kind of respiratory tract foreign body suction device.
[background technology]
At present, when hospital implements to perform the operation to patient, need to implement as required all anesthesia or part anesthesia, usually to go general anesthesia when wherein carrying out major surgery, for sufferer spontaneous respiration is stopped, the doctor can insert endotracheal tube in the patient oral cavity, also insert the respiratory tract negative pressure catheter simultaneously and be used for attracting and getting rid of saliva and the expectorant that the patient's mouth endocrine goes out; Wherein the liquid that oozes out of the disease sites of sufferer also uses the respiratory tract negative pressure catheter to remove; But in the above-mentioned operation process, existing respiratory tract negative pressure catheter usually operation is comparatively loaded down with trivial details, is not easy to nurse's operation.
[summary of the invention]
In order to overcome the deficiency in the background technology, the utility model discloses a kind of respiratory tract foreign body suction device, the suction tube that this utility model utilizes cylindrical shell, depression bar and spring to form makes and inserts saliva and the expectorant that the intraoral suction pipe of patient attracts and eliminating patient's mouth endocrine goes out, and operates comparatively easy.
The realization the technical solution of the utility model is as follows:
A kind of respiratory tract foreign body suction device, comprise cylindrical shell, depression bar, spring, base plate and suction pipe, inwall is provided with internal ring in the upper end of cylindrical shell, the external screw thread of base plate outer edge surface is connected with the female thread that cylindrical shell lower end inwall arranges, wherein the outer edge surface of base plate upper end is provided with rubber ring, one end of suction pipe is fixed on the middle part of base plate, the top outer edge surface of depression bar is arranged in the internal ring of cylindrical shell and matched in clearance, the rubber ring of depression bar lower end piston outer edge surface setting and the inwall of cylindrical shell are slidingly matched, be provided with the through hole of perforation by upper surface to the bottom surfaces of piston of depression bar, the two ends of spring withstand on respectively on piston and the base plate.
Described respiratory tract foreign body suction device, the other end of suction pipe is arranged with at least two holes near the tube wall pressed on ring of end.
Described by above-mentioned disclosure, the beneficial effects of the utility model are:
Respiratory tract foreign body suction device described in the utility model, the suction tube that this utility model utilizes cylindrical shell, depression bar and spring to form, during use suction pipe is inserted in the patient oral cavity, utilize the thumb shutoff to press down the through hole of rear depression bar, then utilize the effect of spring that depression bar is risen, at this moment the negative pressure that forms in the cylindrical shell makes inserts saliva and the expectorant that the intraoral suction pipe of patient attracts and eliminating patient's mouth endocrine goes out, and then takes out suction pipe and by moulded rod, makes saliva and expectorant in the suction pipe flow into spittoon; This utility model operation is comparatively easy, and sufferer is used comparatively comfortable.
