Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of sputum aspirator.
Background technology
Need timely for the sputum in respiratory tract sucking-off in treatment clinical course, unobstructed with Hold up voltage road, ensure gas exchange, prevention and therapy pulmonary infection.Current various big hospital or clinic use closed aspirator to siphon away sputum, and its structure setting method is as follows: be provided with tee T, communicating pipe, sputum aspirator tube, negative pressure control valve, for connecting the pipe joint of sputum recycling bin; Thin film protective jacket is provided with outside sputum aspirator tube; The main tube part of tee T was connected with communicating pipe and both junctions are provided with the air flue switching control pilot that can control both connected states, and a tube portion for tee T is communicated with adapter, and adapter connects respirator loop extension tube; The lower end of communicating pipe is provided with sealing cap, communicating pipe bypass have the syringe pipe that can pass into normal saline; Sputum aspirator tube is movably through the movable span of sealing cap.
During use, open air flue switching control pilot, the main tube part of tee T was communicated with communicating pipe, sputum aspirator tube enters in the respiratory tract of human body through the main tube part of tee T, and operation negative pressure control valve causes negative pressure in sputum aspirator tube, is siphoned away by sputum.After completing suction sputum operation, regain sputum aspirator tube, close air flue switching control pilot, the main tube part of tee T and communicating pipe is made to be in obstructed state, then in syringe pipe, normal saline is passed into, operation negative pressure control valve, to causing negative pressure to suck normal saline in sputum aspirator tube, makes the sputum in sputum aspirator tube be cleaned.
But in actual use, sputum aspirator tube is easy to the effect of tension power and departs from sealing cap, and cause the trouble of operation, careless slightly, the liquid in sputum aspirator tube can flow in thin film protective jacket, pollutes; The head of sputum aspirator tube is through-hole structure, and suction sputum effect is not ideal enough, if sputum is more, sputum is easy to the head blocking sputum aspirator tube.
Utility model content
The purpose of this utility model is to provide a kind of closed sputum aspirator, can be easy to operate, and can siphon away sputum very swimmingly.
The purpose of this utility model is achieved in that a kind of closed sputum aspirator, is provided with tee T, communicating pipe, sputum aspirator tube, negative pressure control valve, pipe joint successively; The thin film protective jacket of protection sputum aspirator tube is provided with outside described sputum aspirator tube; The main tube part of described tee T was connected with communicating pipe and both junctions are provided with the air flue switching control pilot that can control both connected states, a tube portion for described tee T is communicated with rotatable adapter, and described adapter connects respirator loop extension tube; The lower end of described communicating pipe is provided with sealing cap, described communicating pipe bypass have the syringe pipe that can pass into normal saline; Described sputum aspirator tube is movably through the movable span of sealing cap, and the head of described sputum aspirator tube is provided with suction sputum portion, and the external diameter in described suction sputum portion is greater than the diameter of movable span, and the top in described suction sputum portion is provided with sputum suction hole, and the side in suction sputum portion is provided with one or two sputum suction hole.
Operation principle of the present utility model is as follows: sputum suction hole is located at side, the top in suction sputum portion, can cause negative pressure rapidly, can suck sputum rapidly in suction sputum portion; After completing suction sputum operation, retract sputum aspirator tube, the external diameter due to suction sputum portion is greater than the diameter of movable span, and the downside in suction sputum portion can be made to be stuck in movable span place, stops the effect of sputum aspirator tube tension power to depart from sealing cap.
Compared with prior art, the beneficial effects of the utility model are: during use, suction sputum portion is stuck in movable span place, can prevent the effect of sputum aspirator tube tension power from departing from sealing cap; Side, the top in suction sputum portion are equipped with sputum suction hole, can strengthen vacuum effect in sputum aspirator tube further, can siphon away sputum better, can not produce the phenomenon of sputum blocking.
As preferred version of the present utility model, the downside in described suction sputum portion is provided with the location tube coupling that upper end is large, lower end is little.When the downside in suction sputum portion is stuck in movable span place, positioning pipe festival-gathering compresses movable span, strengthens sealing effectiveness further, can not produce leakage phenomenon when saline injection, further define the position in suction sputum portion, make operator can feel resistance stopping drag.
As further preferred version of the present utility model, the main tube part of described tee T goes back bypass the air flue humidification pipe having concurrently and drip medicine function.Play moistening air flue, eliminate the effect of the antibacterial produced in suction sputum process.
Accompanying drawing explanation
Fig. 1 is general assembly drawing of the present utility model.
Fig. 2 is the A portion enlarged drawing in Fig. 1.
Wherein, 1 tee T, 2 air flue humidification pipes, 3 communicating pipes, 4 suction sputum portions, 5 sputum suction holes, 6 sputum aspirator tubes, 7 adapteres, 8 respirator loop extension tubes, 9 air flue switching control pilots, 10 syringe pipes, 11 thin film protective jackets, 12 negative pressure control valves, 13 pipe joints, 14 sealing caps, 15 movable spans, 16 location tube couplings.
Detailed description of the invention
As shown in Figure 1-2, a kind of closed sputum aspirator, is provided with tee T 1, communicating pipe 3, sputum aspirator tube 6, negative pressure control valve 12, pipe joint 13 successively; The thin film protective jacket 11 of protection sputum aspirator tube 6 is provided with outside sputum aspirator tube 6; The main tube part of tee T 1 was connected with communicating pipe 3 and both junctions are provided with the air flue switching control pilot 9 that can control both connected states, and a tube portion for tee T 1 is communicated with rotatable adapter 7, and adapter 7 connects respirator loop extension tube 8; The lower end of communicating pipe 3 is provided with sealing cap 3a, communicating pipe 3 bypass have the syringe pipe 10 that can pass into normal saline; Sputum aspirator tube 6 is movably through the movable span 15 of sealing cap 3a, the head of sputum aspirator tube 6 is provided with suction sputum portion 4, the external diameter in suction sputum portion 4 is greater than the diameter of movable span 15, the top in suction sputum portion 4 is provided with sputum suction hole 5, the side in suction sputum portion 4 is provided with one or two sputum suction hole 5, can ensure that there are enough structural strengths in suction sputum portion 4.
