Description
Technical Field
The utility model belongs to the technical field of medical animal experiments, and particularly relates to an improved gun type manual negative pressure suction device for animal experiments.
Background
The medical profession can involve experimental animal operations in many courses in the study stage of the family, such as functional laboratory experiments, physiological experiments, pharmacological experiments and the like, and can also involve experimental animal operations in many times in the scientific research experiments in the study stage. In the processes of surgery, intubation and the like, particularly under the condition that the method of the undergraduate manipulation is not skillful, the experimental animals can bleed too much, and the wound surface cannot be seen clearly, so that the surgery is affected. In addition, the experimental animal needs general anesthesia before operation, mainly intravenous injection anesthesia, and tracheal intubation after anesthesia, so as to ensure the smoothness of the respiratory tract of the experimental animal in the operation process. Before the trachea cannula is performed, students often cause intratracheal hemorrhage or external blood inflow into blood vessels and the like due to improper operations such as anesthesia, trachea peeling and the like, so that the performance of the trachea cannula is affected, and even the respiratory tract blockage of experimental animals can be caused to cause choking death.
The negative pressure suction device in the prior art is common in clinical surgery, wound surface cleaning and nursing, mainly uses electric operation, and has lower use frequency in experimental animal operation, especially in the stage of teaching experiment of the family. If bleeding is more in the experimental process, usually the hemostatic forceps are used for clamping and then the gauze is used for wiping, and if the blood or secretion in the trachea is more before the trachea cannula, usually the gauze and the cotton swab are used for wiping, and the larger blood clot is clamped out by the ophthalmic forceps, a manual gun type sputum aspirator is usually used in home care, the price is low, the application is convenient, and the principle is that the lower than normal pressure gas pressure state is generated in the device by manually pulling the pull rod, so that sputum and other liquids are sucked out of a body cavity.
The electric negative pressure aspirator is high in power, labor-saving in electric driving, high in price, large in size and heavy, accessories are not matched with experimental animals, later use is required to be maintained, the electric negative pressure aspirator is common in clinical work, the popularization rate of laboratories (especially the teaching laboratory for the family) for performing experimental animal operations is low, and tools such as gauze, cotton balls, tweezers and the like which are commonly used in the experimental animal operation process are low in efficiency, the experimental process is influenced, the experimental animals are dead even, and the waste of consumables is high.
During the operation of experimental animals, fine operations, such as intubation operation of various pipelines, are sometimes required, and the requirement of light source irradiation is met. The laboratory shadowless lamp for experimental animal surgery has lower popularization rate, mainly comprises a lamp standing on a table top or the ground, and a plurality of people often wind around the experiment table when students do experiments, and the lamp often shields the sight of partial classmates and also affects the operation of the classmates due to larger volume. In addition, part of the illuminating lamps still adopt incandescent bulbs, a large amount of heat is generated in the illuminating process, so students in the experimental classroom often abandon the illuminating lamps and select to illuminate with the illumination function of the mobile phone, and if the mobile phone is not completely cleaned and disinfected at the end of the course, the hidden danger of sanitation and safety is left.
