Description

The sputum collecting tube of lung cancer check usefulness

The utility model belongs to the medical inspection utensil, relates in particular to a kind of sputum collecting tube of lung cancer check usefulness.

The pipe shaft of the sputum collecting tube of the lung cancer check usefulness that present hospital generally uses is all cylindrical, its pipe end, be turbination, this obconic structure helps the deposition of cell, also just because the turbination of bottom makes it can't erect placement separately, must be during placement by means of base, promptly on end be inserted in the jack on the base, very inconvenient during use.In addition, the pipe of this kind sputum collecting tube lid adopts rigid plastic to manufacture, and between the mouth of pipe by threaded engagement, the He Guangai that uncaps get swivelling pipe and covers, and is cumbersome, and sealing effectiveness is relatively poor.

It is a kind of simple in structure that the purpose of this utility model is to provide, and can erect the sputum collecting tube of the lung cancer check usefulness of placement separately.

Another purpose of the utility model provides a kind of pipe lid and cooperates closely with the mouth of pipe, and it is comparatively convenient that open and close are covered, lung cancer check the sputum collecting tube of usefulness.

The sputum collecting tube of the utility model lung cancer check usefulness is achieved in that at the bottom of this sputum collecting tube is by cylindrical pipe shaft and turbination pipe to be formed, and is stamped the pipe lid on the mouth of pipe, extends one section its height in the bottom of pipe shaft greater than the cylindrical base at the bottom of the turbination pipe.

The utility model sputum collecting tube has a circle bead on the outer of the described mouth of pipe, soft plastic pipe covers and has two circles and cover the edge, withholds on the mouth of pipe, and its inner cap is along matching with the inwall of the mouth of pipe, matches with bead on the mouth of pipe in the enclosing cover edge.

The utility model is simple in structure, reasonable in design, and is under the situation that does not change inner structure, by reach the purpose that independent setting is placed from the extended base in the bottom of pipe shaft, extremely easy to use.The pipe of the utility model sputum collecting tube lid cooperates closely with pipe shaft, good sealing effect, and it is also very convenient to uncap, close lid.

With reference to the accompanying drawings the utility model sputum collecting tube is further described.

Accompanying drawing is the decomposition cross-sectional schematic of the utility model sputum collecting tube.

From accompanying drawing, can see, the sputum collecting tube of the utility model lung cancer check usefulness is mainly by 6 forming at the bottom of cylindrical pipe shaft 5 and the turbination pipe, extend one section columniform extension in the bottom of pipe shaft 5, it also is base 7, the height of base 7 should be greater than 6 height at the bottom of the turbination pipe, base 7 can directly contact with table top when placing to guarantee to erect, and relies on base 7 that sputum collecting tube steadily is erected on the table top.The body of the utility model sputum collecting tube (comprising pipe shaft 5, the pipe end 6 and base 7) adopts plastics to manufacture, but one-shot forming.The pipe lid 1 of the utility model sputum collecting tube adopts the nonrigid plastic one-shot forming to make, pipe cover and has two on 1 and enclose and to cover the edge, be inner cap along 2 and enclosing cover along 3, close when cover and to cover 1 and withhold on the mouth of pipe and get final product managing, at this moment, inner cap matches with the inwall of the mouth of pipe along 2, and enclosing cover matches with bead 4 on the mouth of pipe outer along 3, sealing effectiveness is fine, and it is also very convenient to uncap.
