Description

Universal negative pressure purulence sucking device

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of universal negative pressure purulence sucking device.

Background technology

In hospital clinical, it is common occurrence that inflammation is suppurated, and the suppuration position can find expression in each position of body surface, and the suppuration area is also had nothing in common with each other, as hemorrhoid, skin ulcer class, the suppuration area is generally bigger, and the acne class shows generally that on the face otitis media is then fallen ill in ear, so, when inhaling pus, what have needs heavy caliber suction nozzle, the small-bore suction nozzle of the needs that have.Pus is messy, smelly, and normally crowded with hands, cotton balls is wiped, and this seems very unhygienic, also causes easily and infects and diffusion.The negative pressure purulence sucking device that adopts is used the round mouth suction nozzle mostly at present, external syringe pump, or the suction of external attraction ball, and the deficiency of its existence: the one, owing to the suction nozzle bore is fixed, so can not be suitable for the attraction of multiple pus face; The 2nd, suction force can not be controlled voluntarily, is difficult for regulating; The 3rd, not flexible of suction nozzle with battery unit can not reducing, has limited range of application.

Summary of the invention

But the purpose of this utility model is to provide a kind of suction nozzle reducing, collapsible, suction force can be controlled voluntarily, range of application is wider universal negative pressure purulence sucking device.

For reaching above purpose, the technical scheme that this utility model adopted is: this universal negative pressure purulence sucking device, by cylindrical shell, suction tube, negative suction system constitutes, the rear port of cylindrical shell is connected with negative suction system is vertical, it is characterized in that in cylindrical shell, establishing suction tube along central axis, the mouth of suction tube along on to the mouth of cylindrical shell along on bonding fixing on elastica, establish two verge rings in the front portion of suction tube, the inwall of two verge rings and cylindrical shell is fixed, the mouth of pipe of suction tube is a circular port, body is a rectangular tube, on a side of body, establish horizontal groove, between intravital two verge rings of tube, establish transmitting gear, horizontal groove engagement on transmitting gear and the suction tube, the handler of transmitting gear stretches out outside the wall of cylindrical shell, and seal by sealing ring, when rotating transmitting gear, the promotion suction tube is flexible, when the bigger skin ulcer face of suction pus area, suction tube is contracted in cylindrical shell, be buckled in directly with the prosopyle of cylindrical shell that suction gets final product on the skin ulcer face, if the pus area that extracts is less, or during than the position, deep, suction tube is stretched out, make elastica be the vertebral body shape, be buckled in the prosopyle of suction tube that suction gets final product on the skin ulcer face.This utility model is also implemented by following measure: described negative suction system comprises piston/cylinder, piston, piston rod, press handle, spring constitutes, piston, piston rod is installed in the piston/cylinder, spring housing is contained in the outer end of piston rod, front end at piston/cylinder is established passage, upper side sets out the gas check valve in the rear end of piston/cylinder, downside is established breather check valve, when pressing press handle, piston moves to left, and the breather check valve on the right of piston is opened, and outgassing nonreturn valve is closed, thereby in the intravital gas suction of tube piston/cylinder, form negative pressure in the cylindrical shell, suction tube begins to take out pus, when unclamping press handle, breather check valve is closed, outgassing nonreturn valve is opened, and under the effect of spring, piston moves to right; The size of its suction force is because of adopting hand, so can regulate voluntarily; Establish pus in the bottom side, rear end of cylindrical shell and spill mouth, pus spills mouth and connects storage pus bottle by sebific duct; Described cylindrical shell, suction tube and aspirator are all used plastic production.

The beneficial effects of the utility model are: compare with the purulence sucking device tool of present use, and highly versatile, applicable multiple pus skin ulcer face and multiple suppuration position, and suction force can control voluntarily, and easy to use.
