Abstract
The utility model discloses a phlegm device is inhaled to ladder tube -shape, including cylinder, piston, piston rod, hook plate, expanding spring, handle and storage sputum flask, the cylinder be the step barrel, the front end is a major progress section of thick bamboo, the rear end is a little step section of thick bamboo, the piston install in a major progress section of thick bamboo, piston rod one end is installed on the piston, and the other end stretches into in the little step section of thick bamboo. The utility model discloses a structure of echelonment is set to the cylinder, and a major progress section of thick bamboo is set to the front end, and the piston setting is in a major progress section of thick bamboo, and consequently the pulling back can produce the suction that more has more than the cylindric phlegm device of inhaling under the condition of the same stroke, and the width through a major progress section of thick bamboo reduces the length of whole device moreover, and the volume is corresponding reducing also, uses and carry all convenience very.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of ladder tubular sputum aspirator.
Background technology
Usual sputum aspirator in the form of piston is all arranged to cylindrical shape, produce suction by pulling piston to be sucked in storage sputum bottle by expectorant, but this traditional sputum aspirator needs two hand operateds, a hands is pinned cylinder one and is only pulled dynamic piston, can not one-handed performance, use inconvenience; And this sputum aspirator majority is designed to straight-tube shape, when produce abundant suction, what just need cylindrical design is longer, so virtually increases the volume of sputum aspirator, uses and carries all inconvenient.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, provides a kind of ladder tubular sputum aspirator.
The purpose of this utility model is the deficiency existed for prior art, provides a kind of ladder tubular sputum aspirator, comprises cylinder, piston, piston rod, hook plate, coil tension spring, handle and storage sputum bottle; Described cylinder is step cylindrical shell, and front end is large step cylinder, and rear end is small stair cylinder, described piston is arranged in large step cylinder, described piston rod one end is arranged on piston, and the other end extend in small stair cylinder, and is connected by the sidewall of coil tension spring with small stair cylinder; Described hook plate is vertically installed on the piston rod, and the lower end sidewall of small stair cylinder is provided with chute, and it is outside that the lower end of described hook plate reaches small stair cylinder by chute, described handle be arranged on the right-hand member of small stair cylinder and hook plate with the use of; The left end of described large step cylinder is also provided with suction nozzle, and this suction nozzle is connected in storage sputum bottle, and described storage sputum bottle also stretches out a sputum aspirator tube.
As preferably, the external diameter of described large step cylinder is the twice of small stair cylinder external diameter.
The width of large step cylinder is comparatively large, therefore also can produce larger suction when short stroke, therefore less than the sputum aspirator volume of cylindrical shape.
As preferably, the right-hand member of described piston rod is also provided with limited block, and described limited block connects coil tension spring.
As preferably, in described suction nozzle, be also provided with filter cotton.
Beneficial effect: this utility model exists following advantage compared with existing technical scheme:
(1) this utility model is sputum aspirator in the form of piston, when using, palm when held handle, pull after finger hooks hook plate, so just drive piston to produce suction, structure simply can realize one-handed performance, then can by piston revert original position by the effect of coil tension spring, realize one-handed performance, very easy to use;
(2) cylinder of the present utility model is arranged to stair-stepping structure, large step cylinder is arranged in front end, piston is arranged in large step cylinder, therefore after pulling when identical stroke, more suction can be produced than the sputum aspirator of cylindrical shape, and the length of whole device is reduced by the width of large step cylinder, volume also reduces accordingly, uses and carries all very convenient.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate this utility model further, the present embodiment is implemented under premised on technical solutions of the utility model, should understand these embodiments and only be not used in restriction scope of the present utility model for illustration of this utility model.
As shown in Figure 1, a kind of ladder tubular sputum aspirator, comprises cylinder 1, piston 2, piston rod 3, hook plate 4, coil tension spring 5, handle 6 and storage sputum bottle 7; Described cylinder 1 is step cylindrical shell, front end is large step cylinder 101, rear end is small stair cylinder 102, described piston 2 is arranged in large step cylinder 101, described piston rod 3 one end is installed on the piston 2, the other end extend in small stair cylinder 102, and is connected with the sidewall of small stair cylinder 102 by coil tension spring 5; Described hook plate 4 is vertically arranged on piston rod 3, and the lower end sidewall of small stair cylinder 102 is provided with chute 8, it is outside that the lower end of described hook plate 4 reaches small stair cylinder 102 by chute 8, described handle 6 be arranged on the right-hand member of small stair cylinder 102 and hook plate 4 with the use of; The left end of described large step cylinder 102 is also provided with suction nozzle 9, and this suction nozzle 9 is connected in storage sputum bottle 7, and described storage sputum bottle 7 also stretches out a sputum aspirator tube 10.
Wherein, the external diameter of large step cylinder 101 is twices of small stair cylinder 102 external diameter; The width of large step cylinder 101 is comparatively large, therefore also can produce larger suction when short stroke, therefore less than the sputum aspirator volume of cylindrical shape.
Wherein, the right-hand member of piston rod 3 is also provided with limited block 11, and described limited block 11 connects coil tension spring 5.
Wherein, filter cotton 12 is also provided with in suction nozzle 9.
This utility model is sputum aspirator in the form of piston, when using, palm when held handle, pull after finger hooks hook plate, so just drive piston to produce suction, structure simply can realize one-handed performance, then can by piston revert original position by the effect of coil tension spring, realize one-handed performance, very easy to use.
Cylinder of the present utility model is arranged to stair-stepping structure, large step cylinder is arranged in front end, piston is arranged in large step cylinder, therefore after pulling when identical stroke, more suction can be produced than the sputum aspirator of cylindrical shape, and the length of whole device is reduced by the width of large step cylinder, volume also reduces accordingly, uses and carries all very convenient.
